Holly Energy Partners, L.P.

Holly Energy Partners, L.P. is a Delaware limited partnership engaged principally in the business of operating a system of refined product and crude oil pipelines, storage tanks, distribution terminals and loading rack assets in west Texas, New Mexico, Utah, Oklahoma, Arizona, Idaho, and Washington. We generate revenues by charging tariffs for transporting refined product and crude oil through our pipelines and by charging fees for terminalling refined products and other hydrocarbons, and storing and providing other services at our terminals. We do not take ownership of products that we transport or terminal, and therefore, we are not directly exposed to changes in commodity prices. We serve refineries of Holly Corporation in New Mexico and Utah under four long-term pipeline, throughput, tankage and/or terminal agreements with Holly Corporation. The first of these agreements relates to the pipelines and terminals contributed to us by Holly Corporation at the time of our initial public offering and expires in 2019. The second of these agreements relates to the intermediate pipelines acquired from Holly Corporation in July 2005 that serve Holly Corporation’s Lovington and Artesia, New Mexico refinery facilities and, as amended, expires in 2024. The third agreement relates to the crude pipelines and tankage assets acquired from Holly Corporation in February 2008 and expires in 2023. The fourth agreement relates to the truck and rail loading/unloading facilities located at Holly Corporation’s Tulsa, Oklahoma refinery and expires in 2024. Holly Corporation controls our general partner and owns a 41% interest in us (before we issue the common units offered hereby or the common units to be issued to Sinclair Tulsa Refining Company — See “Recent Developments” below), including the 2% general partner interest. We also serve Alon USA, Inc.’s, or Alon’s, Big Spring Refinery in Texas under a pipelines and terminals agreement expiring 2020. Our assets currently include:


	•	Pipelines:


	•	approximately 820 miles of refined product pipelines, including 340 miles of leased pipelines, that transport gasoline, diesel and jet fuel principally from Holly Corporation’s Navajo Refinery in New Mexico to its customers in the metropolitan and rural areas of Texas, New Mexico, Arizona, Colorado, Utah and northern Mexico;

	•	approximately 510 miles of refined product pipelines that transport refined products from Alon’s Big Spring Refinery in Texas to its customers in Texas and Oklahoma;

	•	three 65-mile pipelines that transport intermediate feedstocks and crude oil from Holly Corporation’s Lovington, New Mexico refinery facilities to Holly Corporation’s Artesia, New Mexico refinery facilities;

	•	approximately 860 miles of crude oil trunk, gathering and lease connection pipelines which service Holly Corporation’s Lovington and Artesia refining facilities;

S-1


	•	approximately 10 miles of crude oil and refined product pipelines that support Holly Corporation’s Woods Cross Refinery near Salt Lake City, Utah;

	•	a 70% interest in Rio Grande Pipeline Company (“Rio Grande”), a joint venture that owns a 249-mile refined product pipeline that transports liquid petroleum gases, or LPGs, from west Texas to the Texas/Mexico border near El Paso for further transport into northern Mexico (see “Recent Developments” regarding the sale of our 70% interest in Rio Grande, which is expected to close in December 2009); and

	•	a 25% interest in the joint venture that owns and operates the Salt Lake City Pipeline, a new 95 mile intrastate crude oil pipeline system which transports crude oil into the Salt Lake City, Utah area from the Utah terminus of the Frontier Pipeline as well as crude oil flowing from Wyoming and Utah via Plains All American Pipeline, L.P.’s Rocky Mountain Pipeline.


	•	Refined Product Terminals and Refinery Tankage:


	•	four refined product terminals, located in El Paso, Texas; Moriarty and Bloomfield, New Mexico; and Tucson, Arizona, with an aggregate capacity of approximately 1.0 million barrels, that are integrated with our refined product pipeline system that serves Holly Corporation’s Navajo Refinery;

	•	three refined product terminals (two of which are 50% owned), located in Burley and Boise, Idaho and Spokane, Washington, with an aggregate capacity of approximately 500,000 barrels, that serve third-party common carrier pipelines;

	•	one refined product terminal near Mountain Home, Idaho with a capacity of 120,000 barrels, that serves a nearby United States Air Force Base;

	•	two refined product terminals, located in Wichita Falls and Abilene, Texas, and one tank farm in Orla, Texas with aggregate capacity of 480,000 barrels, that are integrated with our refined product pipelines that serve Alon’s Big Spring Refinery;

	•	two refined product truck loading racks, one located within Holly Corporation’s Navajo Refinery that is permitted to load over 40,000 barrels per day (“bpd”) of light refined products, and one located within Holly Corporation’s Woods Cross Refinery, that is permitted to load over 25,000 bpd of light refined products;

	•	a Roswell, New Mexico jet fuel terminal leased through September 2011;

	•	on-site crude oil tankage at Holly Corporation’s Navajo and Woods Cross Refineries having an aggregate storage capacity of approximately 600,000 barrels; and

	•	truck and rail loading/unloading facilities located at Holly Corporation’s Tulsa, Oklahoma refinery.

Recent Developments

On October 19, 2009, our wholly-owned subsidiary, HEP Tulsa LLC, entered into an asset sale and purchase agreement with Sinclair Tulsa Refining Company, or Sinclair, pursuant to which HEP Tulsa LLC will purchase tankage, loading racks and pipeline assets at Sinclair’s refining facility in Tulsa, Oklahoma for a total purchase price of $75 million, consisting of 1,373,609 of our common units to be issued by us to Sinclair (which under the asset sale and purchase agreement are valued at $53.5 million based on the average price of common units during the 20 trading day period prior to the date of the asset sale and purchase agreement) and $21.5 million in cash from HEP Tulsa LLC. We intend to use a portion of the net proceeds of this offering to fund HEP Tulsa LLC’s payment of the $21.5 million cash portion of the total purchase price. For more detailed information regarding the use of proceeds from this offering, see “Use of Proceeds”.

S-2

We refer to the acquisition by HEP Tulsa LLC of tankage, loading racks and pipeline assets from Sinclair as the acquisition of the Sinclair logistics assets.

Simultaneously with the acquisition of the Sinclair logistics assets and under the same asset sale and purchase agreement, Holly Refining & Marketing-Tulsa LLC, an affiliate of our general partner, will purchase Sinclair’s refining facility in Tulsa, Oklahoma for an aggregate consideration of $128.5 million, consisting of $74 million of Holly Corporation common stock to be issued by Holly Corporation to Sinclair and $54.5 million in cash from Holly Corporation. In addition, Holly Refining & Marketing-Tulsa LLC will purchase the inventory at the site.

In connection with the closing of the acquisition of the Sinclair logistics assets, we anticipate that Holly Refining & Marketing-Tulsa LLC will enter into a 15 year pipelines, tankage and loading rack throughput agreement with HEP Tulsa LLC, to pay us, subject to various adjustments:


	•	a pipeline tariff of $.10 for each barrel of refined products moved on the pipelines acquired in connection with the Sinclair logistics assets with a guaranteed minimum throughput of 60,000 bpd of crude oil or refined products moved;

	•	a tankage base tariff of $.30 for each barrel of refined products stored using tankage acquired in connection with the Sinclair logistics assets with a guaranteed minimum throughput of 80,000 bpd of refined products, $.10 per barrel for volumes in excess of 80,000 bpd to 120,000 bpd, and $.22 per barrel for volumes in excess of 120,000 bpd; and

	•	a loading racks tariff of $.30 for each barrel of refined products, LPG, and heavy products loaded over the loading racks acquired in connection with the Sinclair logistics assets with a guaranteed minimum throughput of 26,000 bpd.

The assets acquired from Sinclair include tanks with a combined capacity of 1,362,500 bbls of refined products, a light products truck loading rack, a propane truck loading rack, and an asphalt truck loading rack, as well as refined products delivery pipelines which are connected to common carrier pipelines serving the Sinclair Tulsa refinery.

On October 19, 2009, BP Plc, our Rio Grande joint venture partner, consented to an agreement between us, HEP Navajo Southern, L.P. (one of our wholly-owned subsidiaries) and Enterprise Products Operating LLC (“Enterprise”) under which we have agreed to sell HEP Navajo Southern, L.P.’s 70% ownership interest in Rio Grande to Enterprise for $35.0 million. We expect the closing of this transaction to occur in December 2009.

On August 18, 2009, 7,000,000 of our subordinated units held by a subsidiary of Holly Corporation converted into an equal number of our common units. Holly Corporation has the right to cause us to register for resale under the Securities Act of 1933 those common units held by Holly Corporation.

On August 1, 2009, we acquired from Holly Refining & Marketing-Tulsa LLC, for a purchase price of $17.5 million, certain truck and rail loading/unloading facilities located at Holly Corporation’s Tulsa, Oklahoma refinery.

Competitive Strengths

We believe our business possesses the following competitive strengths:

We operate a substantial part of our business under long-term contracts, which provides significant stability to our future cash flows. We conduct a significant portion of our operations pursuant to long-term contracts, which we believe will enhance the stability and predictability of our revenues and cash flows. Revenues from contracts extending beyond one year constituted approximately 88% of our revenues for the fiscal year ended December 31, 2008. We have entered into four long-term contracts with Holly Corporation expiring in 2019, 2023, and two expiring in 2024, not including the contract with Holly Corporation relating to the Sinclair logistics assets. We also have

S-3

long-term contracts with Alon. The long-term contracts representing a majority of our revenue stream from Alon expire between 2018 and 2020. In addition, where we operate under contracts with terms of less than one year, we believe our long-standing customer relationships will lead to ongoing business and the renewal of such short-term contracts.

Our assets are efficient and well maintained. We continually invest in the maintenance and integrity of our assets, including state-of-the-art internal mechanical integrity inspection and repair programs to comply with federal regulations. Since 1998, we have inspected and, to the extent required, repaired 100% of the total miles of the pipelines that we owned upon our initial public offering in 2004, 100% of the intermediate pipelines acquired from Holly Corporation in 2005 and 100% of the pipelines acquired from Alon in 2005 using internal inspection devices known as “smart pigs”, which have instruments capable of detecting cracks, line erosion and other structural deficiencies. The operating pressures of these lines have been hydrotested as required by the Department of Transportation. All of our existing pipeline and terminal assets are operated via satellite communications systems from our control center in Artesia, New Mexico. The control center operates with state-of-the-art computer systems designed to continuously monitor real time operational data, including product quantities, flow rates and pressures.

We have a strategic relationship with Holly Corporation, which provides us with access to stable volumes, growth opportunities and management expertise. A substantial majority of our existing petroleum pipelines are directly linked to Holly Corporation’s refineries and provide Holly Corporation with the safest and most cost-effective means to transport and distribute petroleum products to its major markets. Following our acquisition from Holly Corporation of certain pipeline and tankage assets effective March 1, 2008, Holly Corporation now transports through our petroleum pipelines or loading racks 100% of the refined products from its Navajo Refinery and its Woods Cross Refinery, 100% and 15% of the crude oil coming into its Navajo Refinery and Woods Cross Refinery, respectively, and 100% of the intermediate products between Navajo Refinery’s Artesia and Lovington facilities. Holly Corporation has agreed to continue using our assets to transport, terminal and store petroleum products pursuant to three separate pipelines and terminals agreements expiring in 2019, 2023 and 2024. In addition, in connection with our acquisition from Holly Corporation of certain truck and rail loading/unloading facilities located at Holly Corporation’s existing Tulsa, Oklahoma refinery, Holly Corporation has agreed to use these facilities with a minimum guaranteed throughput of 12,500 bpd for 15 years. Furthermore, Holly Corporation has a significant economic interest to see that our pipeline and terminal assets are managed in the best interests of unitholders because it and its affiliates own the 2% general partner interest and a 39% limited partner interest in us (before we issue the common units offered hereby and the issuance of common units to Sinclair in connection with the acquisition of the Sinclair logistics assets) and certain incentive distribution rights. Our recent investment in the Salt Lake City Pipeline, and our investment in the previously announced UNEV Pipeline (which will run from Salt Lake City, Utah to Las Vegas, Nevada), assuming in the case of the UNEV Pipeline that such pipeline is completed and we exercise our option to purchase Holly Corporation’s 75% interest in such pipeline, along with our proposed purchase of the Sinclair logistics assets, will serve to further strengthen our relationship with Holly Corporation.

We are contractually and strategically positioned to benefit from growth initiatives by Holly Corporation. In the past four years, we benefited from Holly Corporation’s expansions of its Navajo and Woods Cross Refineries as well as Holly Corporation’s purchase of Sunoco Inc.’s Tulsa refinery. In the event that Holly Corporation further expands its Navajo or Woods Cross Refineries, we believe that the additional production may also be transported, stored and distributed through our existing pipelines and terminals. We recently benefited from two such projects. On July 22, 2008, Holly Corporation announced an agreement by one of its subsidiaries to transport crude oil on Centurion Pipeline L.P.’s pipeline from Cushing, Oklahoma to Centurion’s Slaughter station in west Texas. In connection with such agreement, Holly Corporation approved capital expenditures of up to $90.0 million to build the necessary infrastructure, including a 70-mile pipeline from Centurion’s Slaughter station in west Texas to Lovington, New Mexico that was recently completed and is

S-4

expected to be fully operational in November 2009, a recently completed 37-mile pipeline project that connects our Artesia crude gathering system to Holly Corporation’s Lovington facility, and a 65-mile pipeline from Lovington to Artesia, New Mexico which has been completed and was recently acquired by us. Under provisions of our omnibus agreement with Holly Corporation we will have an option to purchase Holly Corporation’s investment in these additional transportation assets at a purchase price to be negotiated with Holly Corporation. On August 1, 2009, after Holly Corporation’s purchase of Sunoco Inc.’s Tulsa refinery, we purchased certain truck and rail loading/unloading facilities located at that refinery for a purchase price of $17.5 million. Holly Refining & Marketing-Tulsa LLC entered into a 15-year equipment and throughput agreement with us to pay us a per barrel fee for each barrel loaded or unloaded at the truck and rail loading facilities.

Substantially all of our assets serve markets with above average population growth. Our pipelines and terminals serve our customers’ marketing operations in the Southwest and Rocky Mountain regions of the United States as well as northern Mexico and the Mid-Continent region. In many of our customers’ core markets, demand for petroleum products exceeds local production, due in part to population growth rates that are higher than the national average. We expect that the population growth in the states of Texas, New Mexico, Colorado, Utah, Washington, Nevada, Arizona, Idaho, and the Mid-Continent region will result in increased demand for petroleum products shipped on our pipelines and through our terminals.

We have an experienced management team. We benefit from the experience and long-standing industry relationships of our senior management team. Our senior management has an average of over 25 years of experience in the energy industry.

Partnership Structure and Management

As is common with publicly traded limited partnerships and in order to maximize operational flexibility, we conduct our operations through subsidiaries. We have three direct subsidiaries: Holly Energy Finance Corp., Holly Energy Partners — Operating, L.P., a limited partnership that conducts all of our operations through itself and its subsidiaries, and HEP Logistics GP, L.L.C., its general partner. Holly Energy Partners — Operating, L.P. owns directly or indirectly 100% of the membership or partnership interests in its subsidiaries, other than Rio Grande Pipeline Company, in which it indirectly owns a 70% interest, and SLC Pipeline LLC in which it indirectly owns a 25% interest.

Holly Logistic Services, L.L.C., as the general partner of HEP Logistics Holdings, L.P., our general partner, manages our operations and activities. Neither our general partner nor the board of directors of Holly Logistic Services, L.L.C. are elected by our unitholders. Unlike shareholders in a publicly traded corporation, our unitholders are not entitled to elect the directors of Holly Logistic Services, L.L.C.

The chart on page S-6 depicts the current structure and ownership of Holly Energy Partners, L.P., our operating partnership and its subsidiaries prior to this offering of common units and the issuance of common units to Sinclair in connection with the acquisition of the Sinclair logistics assets.

The Offering

The summary below describes the principal terms of the common units offered hereby. Certain of the terms and conditions described below are subject to important limitations and exceptions. You should read the full text and more specific details contained elsewhere in this prospectus supplement and in the base prospectus under the heading “Description of Our Common Units And Preferred Units”.


Common units offered		1,900,000 common units (or 2,185,000 common units if the underwriters’ over-allotment option is exercised in full).

Units outstanding before this offering		17,582,400 common units and 937,500 Class B subordinated units.

Units outstanding after this offering		19,482,400 common units, or 19,767,400 common units if the underwriters’ over-allotment option is exercised in full, and 937,500 Class B subordinated units. We will issue an additional 1,373,609 common units to Sinclair as a portion of the aggregate consideration for the acquisition of the Sinclair logistics assets.

Use of proceeds		We will receive net proceeds of approximately $ million from the sale of the 1,900,000 common units we are offering after deducting underwriting discounts but before paying offering expenses, or approximately $ million if the underwriters’ over-allotment option is exercised in full. We intend to use a portion of the net proceeds of this offering, including any exercise of the underwriters’ over-allotment option, to fund HEP Tulsa LLC’s payment of the $21.5 million cash portion of the $75.0 million total purchase price for the pending acquisition of the Sinclair logistics assets and to pay costs related to that acquisition. We intend to use the remaining net proceeds either to pay a portion of the purchase price for our potential acquisition from Holly Corporation of its investments in two pipeline projects pursuant to our option to purchase those investments at prices to be negotiated with Holly Corporation or, instead, to repay bank debt incurred under our credit agreement, for other potential future acquisitions or for general partnership purposes. If the acquisition of the Sinclair logistics assets does not close, we intend to use the net proceeds of this offering for one or more of the following: to pay for all or substantially all of the purchase price and related costs for the potential acquisitions from Holly Corporation described above, to repay bank debt incurred under our credit agreement, for other potential future acquisitions or for general partnership purposes. For more detailed information regarding the use of proceeds from this offering, see “Use of Proceeds”.

Cash distributions		Under our partnership agreement, we must distribute all of our cash on hand within 45 days after the end of each quarter, after payment of fees and expenses and the establishment of cash reserves by our general partner in its discretion. We refer to this cash as “available cash” and we define this term in our partnership agreement.

		If cash distributions per common unit exceed $0.50 in any quarter, our general partner will receive, in addition to amounts associated with its 2% general partner interest, increasing percentages, up to 50%, of the cash we distribute

S-7


		in excess of that amount. We refer to the general partner’s right to receive such distributions as “incentive distribution rights”. The most recent cash distribution declared of $0.795 per common unit will provide unitholders and our general partner each with 50% of the marginal percentage interest in distributions. For a description of our cash distribution policy and the incentive distribution rights, please read “Cash Distribution Policy” in the accompanying base prospectus.

Subordination period		In addition to our common units, we previously issued two separate classes of subordinated units representing limited partnership interests, and the rights of the holders of each class of subordinated units to participate in distributions are subordinated to the rights of the holders of the common units. When the subordination period for any class of subordinated units ends, all remaining subordinated units of such class will convert into common units on a one-for-one basis and will thereafter participate pro rata with the other common units in distributions of available cash. For more information regarding the effects of the end of the subordination period applicable to each class of subordinated units, see the discussion under “Cash Distribution Policy — Subordination Periods — Effect of Expiration of the Subordination Period” in the base prospectus accompanying this prospectus supplement.

		In August 2009, all of the conditions necessary to end the subordination period for the 7,000,000 subordinated units owned by our general partner were met and the units were converted into our common units on a one-for-one basis. In addition, under our partnership agreement, because the subordination period for this class of subordinated units has expired, we may issue an unlimited number of limited partner interests of any type without the approval of our unitholders.

		With respect to the 937,500 subordinated units held by Alon USA (all of which are designated as our Class B subordinated units), the subordination period will end on the last day of any quarter ending on or after March 31, 2010 if Alon USA has not defaulted on its minimum volume commitment payment obligations under our pipelines and terminals agreement with Alon USA for certain prior periods, subject to certain grace periods. In addition, the subordination period for units held by Alon USA will terminate if our general partner is removed without cause.

Estimated ratio of taxable income to distributions		We estimate that if you own the common units you purchase in this offering through the record date for distributions with respect to the quarter ending December 31, 2011, you will be allocated, on a cumulative basis, an amount of federal taxable income for the taxable years 2009 through 2011 that will be 25% or less of the cash distributed with respect to such common units for that period. Please read “Certain United States Federal Income Tax Considerations” in this prospectus supplement for the basis of this estimate.

Non-GAAP Financial Measures

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is calculated as net income attributable to Holly Energy Partners, L.P. plus (i) interest expense net of interest income, (ii) state income tax and (iii) depreciation and amortization. EBITDA is not a calculation based upon U.S. GAAP. EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors and commercial banks, to assess:


	•	the financial performance of our assets without regard to financing methods, capital structure or historical cost basis;

	•	the ability of our assets to generate cash sufficient to pay interest on our indebtedness and to make distributions to our partners;

	•	our operating performance and return on invested capital as compared to those of other companies in the pipelines and terminals business, without regard to financing methods, capital structure or historical cost basis; and

	•	our compliance with certain financial covenants included in our debt agreements.

EBITDA should not be considered an alternative to net income, operating income, cash flow from operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. GAAP. EBITDA excludes some, but not all, items that affect net income and operating income, and these measures may vary among other companies. Therefore, EBITDA as presented below may not be comparable to similarly titled measures of other companies.

The following table presents a reconciliation of EBITDA to the most directly comparable GAAP financial measure for each of the periods indicated.

Distributable cash flow is used as a supplemental financial measure by our management and is presented here because it is a widely accepted financial indicator used by investors to compare

S-12

partnership performance. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating.

Distributable cash flow is not a calculation based upon U.S. GAAP. However, the amounts included in the calculation are derived from amounts separately presented in our consolidated financial statements, with the exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or as an alternative to net income or operating income, as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies.

The following table presents a reconciliation of distributable cash flow to the most directly comparable GAAP financial measure for each of the periods indicated.

(1)		Under provisions of accounting standards codification (“ASC”) topic “Business Combinations” (previously statement of financial accounting standards (“SFAS”) No. 141(R)), effective January 1, 2009, we were required to expense rather than capitalize acquisition costs of $2.5 million paid to Holly Corporation associated with our joint venture agreement with Plains All American Pipeline, L.P. that closed in March 2009. As these costs directly related to our interest in the new joint venture pipeline and are similar to expansion capital expenditures, we have added back those costs to arrive at distributable cash flow.

(2)		Maintenance capital expenditures represent capital expenditures made to replace partially or fully depreciated assets in order to maintain the existing operating capacity of our assets and to extend their useful lives. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, and safety and to comply with environmental regulations.

RISK FACTORS

This offering involves a high degree of risk, including the risks described below and other risks described in our Annual Report on Form 10-K for the year ended December 31, 2008, our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2009, June 30, 2009, and September 30, 2009, and the risks described in any other documents incorporated by reference into this prospectus. You should carefully consider all of these risks together with all of the other information included in this prospectus and the documents incorporated by reference herein before deciding to invest in the common units offered hereby. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business operations. If any of the following risks actually occurs, our business, financial condition or results of operations could be materially and adversely affected. In that case, our ability to pay distributions on our common units may be reduced, the trading price of our securities could decline, and you could lose all or part of your investment.

We depend on Holly Corporation and particularly its Navajo Refinery for a majority of our revenues; if those revenues were significantly reduced or if Holly Corporation’s financial condition materially deteriorated, there would be a material adverse effect on our results of operations.

For the year ended December 31, 2008, Holly Corporation accounted for 72% of the revenues of our petroleum product and crude pipelines and 70% of the revenues of our terminals and truck loading racks. We expect to continue to derive a majority of our revenues from Holly Corporation for the foreseeable future, and the percentage of revenues from Holly Corporation are expected to increase following the acquisition of the Sinclair logistics assets and the disposition of our interest in the Rio Grande pipeline. If Holly Corporation satisfies only its minimum obligations under the four pipeline, throughput, tankage and/or terminal agreements we entered into with Holly Corporation or is unable to meet its minimum annual payment commitment for any reason, including due to prolonged downtime or a shutdown at the Navajo Refinery, the Woods Cross Refinery or the Tulsa refinery, our revenues and cash flow would decline.

Any significant curtailing of production at the Navajo Refinery could, by reducing throughput in our pipelines and terminals, result in our realizing materially lower levels of revenues and cash flow for the duration of the shutdown. For the year ended December 31, 2008, production from the Navajo Refinery accounted for 67% of the throughput volumes transported by our refined product and crude pipelines. The Navajo Refinery also received 100% of the petroleum products shipped on our intermediate pipelines. Operations at the Navajo Refinery could be partially or completely shut down, temporarily or permanently, as the result of:


	•	competition from other refineries and pipelines that may be able to supply the refinery’s end-user markets on a more cost-effective basis;

	•	operational problems such as catastrophic events at the refinery, labor difficulties or environmental proceedings or other litigation that compel the cessation of all or a portion of the operations at the refinery;

	•	planned maintenance or capital projects;

	•	increasingly stringent environmental laws and regulations, such as the U.S. Environmental Protection Agency’s gasoline and diesel sulfur control requirements that limit the concentration of sulfur in motor gasoline and diesel fuel for both on-road and non-road usage as well as various state and federal emission requirements that may affect the refinery itself and potential future climate change regulations;

	•	an inability to obtain crude oil for the refinery at competitive prices; or

S-14


	•	a general reduction in demand for refined products in the area due to:


	•	a local or national recession or other adverse economic condition that results in lower spending by businesses and consumers on gasoline and diesel fuel;

	•	higher gasoline prices due to higher crude oil prices, higher taxes or stricter environmental laws or regulations; or

	•	a shift by consumers to more fuel-efficient or alternative fuel vehicles or an increase in fuel economy, whether as a result of technological advances by manufacturers, legislation either mandating or encouraging higher fuel economy or the use of alternative fuel or otherwise.

The magnitude of the effect on us of any shutdown would depend on the length of the shutdown and the extent of the refinery operations affected by the shutdown. We have no control over the factors that may lead to a shutdown or the measures Holly Corporation may take in response to a shutdown. Holly Corporation makes all decisions at the Navajo Refinery concerning levels of production, regulatory compliance, refinery turnarounds (planned shutdowns of individual process units within a refinery to perform major maintenance activities), labor relations, environmental remediation, emission control, and capital expenditures; is responsible for all related costs; and is under no contractual obligation to us to maintain operations at the Navajo Refinery.

Furthermore, Holly Corporation’s obligations under our three pipeline, tankage and/or terminal agreements with Holly Corporation, would be temporarily suspended during the occurrence of a force majeure that renders performance impossible with respect to an asset for at least 30 days. If such an event were to continue for a year, we or Holly Corporation could terminate the agreements. The occurrence of any of these events could reduce our revenues and cash flows.

We depend on Alon and particularly its Big Spring Refinery for a substantial portion of our revenues; if those revenues were significantly reduced, there would be a material adverse effect on our results of operations.

For the year ended December 31, 2008, Alon accounted for 16% of the combined revenues of our petroleum product and crude pipelines and of our terminals and truck loading racks, including revenues we received from Alon under a capacity lease agreement.

On February 18, 2008, Alon experienced an explosion and fire at its Big Spring Refinery that resulted in the shutdown of production. In early April 2008, Alon reopened its Big Spring Refinery and resumed production at one-half of refinery capacity until late September when production was restored to full capacity. Lost production and reduced operations attributable to this incident resulted in a significant decrease in third party shipments and related revenues on our refined product pipelines during the first nine months of 2008. As a result of related contractual minimum commitments and resulting shortfall billings, the incidents did not materially affect our distributable cash flow.

Another decline in production at Alon’s Big Spring Refinery would materially reduce the volume of refined products we transport and terminal for Alon. As a result, our revenues would be materially adversely affected. The Big Spring Refinery could partially or completely shut down its operations, temporarily or permanently, due to factors affecting its ability to produce refined products or for planned maintenance or capital projects. Such factors would include the factors discussed above under the discussion of risk factors for the Navajo Refinery.

The magnitude of the effect on us of any shutdown depends on the length of the shutdown and the extent of the refinery operations affected. We have no control over the factors that may lead to a shutdown or the measures Alon may take in response to a shutdown. Alon makes all decisions and is responsible for all costs at the Big Spring Refinery concerning levels of production, regulatory compliance, refinery turnarounds, labor relations, environmental remediation, emission control, and capital expenditures.

S-15

In addition, under the Alon pipelines and terminals agreement, if we are unable to transport or terminal refined products that Alon is prepared to ship, then Alon has the right to reduce its minimum volume commitment to us during the period of interruption. If a force majeure event occurs beyond the control of either of us, we or Alon could terminate the Alon pipelines and terminals agreement after the expiration of certain time periods. The occurrence of any of these events could reduce our revenues and cash flows.

Our leverage may limit our ability to borrow additional funds, comply with the terms of our indebtedness or capitalize on business opportunities.

As of September 30, 2009, the principal amount of our total outstanding debt was $430.0 million. See “Capitalization’ for additional information. Our results of operations, cash flows and financial position could be adversely affected by significant increases in interest rates above current levels. Various limitations in our Credit Agreement and the indentures for our outstanding 61/4% senior notes due 2015 may reduce our ability to incur additional debt, to engage in some transactions and to capitalize on business opportunities. Any subsequent refinancing of our current indebtedness or any new indebtedness could have similar or greater restrictions.

Our leverage could have important consequences. We will require substantial cash flow to meet our payment obligations with respect to our indebtedness. Our ability to make scheduled payments, to refinance our obligations with respect to our indebtedness or our ability to obtain additional financing in the future will depend on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and other factors. We believe that we will have sufficient cash flow from operations and available borrowings under our Credit Agreement to service our indebtedness. However, a significant downturn in our business or other development adversely affecting our cash flow could materially impair our ability to service our indebtedness. If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to refinance all or a portion of our debt or sell assets. We cannot assure you that we would be able to refinance our existing indebtedness at maturity or otherwise or sell assets on terms that are commercially reasonable.

The instruments governing our debt contain restrictive covenants that may prevent us from engaging in certain beneficial transactions. The agreements governing our debt generally require us to comply with various affirmative and negative covenants including the maintenance of certain financial ratios and restrictions on incurring additional debt, entering into mergers, consolidations and sales of assets, making investments and granting liens. Additionally, our contribution agreements with Alon, and our purchase and contribution agreements with Holly Corporation with respect to the intermediate pipelines and the crude pipelines and tankage assets, restrict us from selling the pipelines and terminals acquired from Alon or Holly Corporation, as applicable, and from prepaying more than $30.0 million of our outstanding 61/4% senior notes due 2015 until 2015 and any of the $171.0 million borrowed under the Credit Agreement for the purchase of the crude pipelines and tankage assets until 2018, subject to certain limited exceptions. Our leverage may adversely affect our ability to fund future working capital, capital expenditures and other general partnership requirements, future acquisitions, construction or development activities, or to otherwise fully realize the value of our assets and opportunities because of the need to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness or to comply with any restrictive terms of our indebtedness. Our leverage may also make our results of operations more susceptible to adverse economic and industry conditions by limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate and may place us at a competitive disadvantage as compared to our competitors that have less debt.

S-16

We may not be able to obtain funding on acceptable terms or at all because of volatility and uncertainty in the credit and capital markets. This may hinder or prevent us from meeting our future capital needs.

While the domestic capital markets have shown signs of improvement in 2009, global financial markets and economic conditions have been, and continue to be, disrupted and volatile due to a variety of factors, including significant write-offs in the financial services sector, declining consumer confidence, increased unemployment, geopolitical issues, and the current weak economic conditions. In addition, the fixed-income markets have experienced periods of extreme volatility which negatively impacted market liquidity conditions. As a result, the cost of raising money in the debt and equity capital markets has increased volatility, while the availability of funds from those markets has diminished significantly at times. In particular, as a result of concerns about the stability of financial markets generally and the solvency of lending counterparties specifically, the cost of obtaining money from the credit markets generally may increase as many lenders and institutional investors increase interest rates, enact tighter lending standards, refuse to refinance existing debt on similar terms or at all and reduce, or in some cases cease, to provide funding to borrowers. In addition, lending counterparties under existing revolving credit facilities and other debt instruments may be unwilling or unable to meet their funding obligations. Due to these factors, we cannot be certain that new debt or equity financing will be available on acceptable terms. If funding is not available when needed, or is available only on unfavorable terms, we may be unable to meet our obligations as they come due. Moreover, without adequate funding, we may be unable to execute our growth strategy, complete future acquisitions or announced and future pipeline construction projects, take advantage of other business opportunities or respond to competitive pressures, any of which could have a material adverse effect on our revenues and results of operations.

We may not be able to fully execute our growth strategy if we encounter illiquid capital markets or increased competition for investment opportunities.

Our strategy contemplates growth through the development and acquisition of crude, intermediate and refined products transportation and storage assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses to enhance our ability to compete effectively and diversifying our asset portfolio, thereby providing more stable cash flow. We regularly consider and enter into discussions regarding, and are currently contemplating and/or pursuing, potential joint ventures, stand alone projects or other transactions that we believe will present opportunities to realize synergies, expand our role in our chosen businesses and increase our market position.

We will require substantial new capital to finance the future development and acquisition of assets and businesses. Any limitations on our access to capital will impair our ability to execute this strategy. If the cost of such capital becomes too expensive, our ability to develop or acquire accretive assets will be limited. We may not be able to raise the necessary funds on satisfactory terms, if at all. The primary factors that influence our cost of equity include market conditions, fees we pay to underwriters and other offering costs, which include amounts we pay for legal and accounting services. The primary factors influencing our cost of borrowing include interest rates, credit spreads, covenants, underwriting or loan origination fees and similar charges we pay to lenders.

In addition, we are experiencing increased competition for the types of assets and businesses we have historically purchased or acquired. Increased competition for a limited pool of assets could result in our losing to other bidders more often or acquiring assets at less attractive prices. Either occurrence would limit our ability to fully execute our growth strategy. Our inability to execute our growth strategy may materially adversely affect our ability to maintain or pay higher distributions in the future.

S-17

USE OF PROCEEDS

We will receive net proceeds of approximately $ million from the sale of the 1,900,000 common units we are offering after deducting underwriting discounts but before paying offering expenses, or approximately $ million if the underwriters’ over-allotment option is exercised in full.

We intend to use a portion of the net proceeds of this offering, including any exercise of the underwriters’ over-allotment option, to fund HEP Tulsa LLC’s payment of the $21.5 million cash portion of the $75.0 million total purchase price for the pending acquisition of the Sinclair logistics assets and to pay costs related to that acquisition. We intend to use the remaining net proceeds either to pay a portion of the purchase price for our potential acquisition from Holly Corporation of its investments in two pipeline projects (a 70-mile pipeline from Centurion Pipeline L.P.’s Slaughter station in west Texas to Lovington, New Mexico and a 37-mile pipeline that connects our Artesia crude gathering system to Holly Corporation’s Lovington facility) pursuant to our option to purchase those investments at prices to be negotiated with Holly Corporation or, instead, to repay bank debt incurred under our credit agreement, for other potential future acquisitions or for general partnership purposes.

The pending acquisition of the Sinclair logistics assets is subject to customary closing conditions, including regulatory approval. If that acquisition does not close, we intend to use the net proceeds of this offering for one or more of the following: to pay for all or substantially all of the purchase price and related costs for our potential acquisitions from Holly Corporation of its investments in the two pipeline projects described above, to repay bank debt incurred under our credit agreement, for other potential future acquisitions or for general partnership purposes. For more information regarding the acquisition of the Sinclair logistics assets, see “Recent Developments”.

The bank debt that may be repaid with the net proceeds of this offering was incurred primarily to fund capital expenditures, including the acquisition from Holly Corporation of a newly constructed intermediate pipeline from their Lovington facility to their Artesia, New Mexico facility in June 2009 for $34.2 million and the truck and rail loading/unloading facilities at Holly Corporation’s Tulsa refinery in August 2009 for $17.5 million. Indebtedness under the Credit Agreement bears interest, at our option, at either (a) the reference rate as announced by the administrative agent plus an applicable margin (ranging from 0.25% to 1.50%) or (b) at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus an applicable margin (ranging from 1.00% to 2.50%). In each case, the applicable margin is based upon the ratio of our funded debt (as defined in the Credit Agreement) to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the Credit Agreement). The Credit Agreement matures on August 27, 2011. At September 30, 2009, we had $245 million of borrowings outstanding under our credit agreement.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The tax consequences to you of an investment in our common units will depend in part on your own tax circumstances. For a discussion of the principal federal income tax considerations associated with our operations and the purchase, ownership and disposition of our common units, please read “Material Tax Consequences” beginning on page 38 in the accompanying base prospectus, as updated and supplemented by the paragraphs included herein. You are urged to consult with your own tax advisor about the federal, state, local and foreign tax consequences particular to your circumstances.

Tax Opinion of Fulbright & Jaworski L.L.P.

Subject to the representations, assumptions, qualifications and limitations stated in the accompanying prospectus and as modified and supplemented by this prospectus supplement, Fulbright & Jaworski L.L.P. concurs with the statements contained in the section captioned “Material Tax Consequences” beginning on page 38 of the accompanying base prospectus, to the extent that such statements constitute matters of law and legal conclusions. In rendering its opinion that we will be classified as a partnership and our operating partnership will be disregarded as an entity separate from us for federal income tax purposes, Fulbright & Jaworski L.L.P. (1) has assumed the accuracy of the opinion of Vinson & Elkins L.L.P. to the effect that we were classified as a partnership and our operating partnership was disregarded as an entity separate from us for each taxable year ending prior to January 1, 2009, as stated in the accompanying base prospectus and (2) has relied on factual representations made by us and our general partner including that (a) neither we, the general partner of the operating partnership nor the operating partnership has elected or will elect to be classified as an association taxable as a corporation for federal income tax purposes, and (b) for each taxable year ending after January 1, 2009, at least 90% of our gross income has been and will be income from activities that Fulbright & Jaworski L.L.P. has opined or will opine is “qualifying income” within the meaning of Section 7704(d) of the Internal Revenue Code, as amended (the “Internal Revenue Code”).

Partnership Status

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income tax purposes. We have not requested, and do not plan to request, a ruling from the IRS on this or any other tax matter affecting us. Instead, we will rely on the opinion of Fulbright & Jaworski, L.L.P. that we will be classified as a partnership for federal income tax purposes.

Current law may change so as to cause us to be treated as a corporation for federal income tax purposes or otherwise subject us to entity-level taxation. At the federal level, legislation has been proposed that would eliminate partnership tax treatment for certain publicly traded partnerships. Although such legislation would not apply to us as currently proposed, it could be amended prior to enactment in a manner that does apply to us. We are unable to predict whether any of these changes, or other proposals will ultimately be enacted. Any such changes could negatively impact the value of an investment in our common units. Moreover, any such changes may or may not be applied retroactively. At the state level, because of widespread state budget deficits and other reasons, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. For example, we are required to pay Texas franchise tax at a maximum effective rate of 0.7% of our gross income apportioned to Texas in the prior year. Imposition of such a tax on us by Texas and, if applicable, by any other state will reduce the cash available for distribution to you.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which is currently a maximum of 35%, and would likely pay state income tax at varying rates. Distributions to you would generally be taxed

S-21

again as corporate distributions, and no income, gains, losses or deductions would flow through to you. Because a tax would be imposed upon us as a corporation, our cash available for distribution to you would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to the unitholders, likely causing a substantial reduction in the value of our common units. Please read “Material Tax Consequences — Partnership Status” in the accompanying base prospectus for additional information regarding our partnership status.

Tax Consequences of Unit Ownership

Tax Rates. In general, the highest marginal federal income tax rate applicable to ordinary income of individuals is currently 35%, and the highest marginal federal income tax rate applicable to long-term capital gains (generally, capital gains on certain assets held for more than 12 months) of individuals is 15%. However, absent new legislation extending the current rates, beginning January 1, 2011, the highest marginal federal income tax rate applicable to ordinary income and long-term capital gains of individuals will increase to 39.6% and 20%, respectively.

Allocation of Income, Gain, Loss and Deduction. In general, if we have a net profit, our items of income, gain, loss and deduction will be allocated among our general partner and the unitholders in accordance with their percentage interests in us. At any time that distributions are made to the common units in excess of distributions to the subordinated units, or incentive distributions are made to our general partner, gross income will be allocated to the recipients to the extent of these distributions. If we have a net loss, that loss will be allocated first to our general partner and the unitholders in accordance with their percentage interests in us to the extent of their positive capital accounts and, second, to our general partner.

Specified items of our income, gain, loss and deduction will be allocated to account for (i) any difference between the tax basis and fair market value of our assets that exists at the time of an offering and (ii) any difference between the tax basis and fair market value of any property contributed to us by our general partner and its affiliates that exists at the time of contribution, referred to in this discussion as the “Adjusted Property”. The effect of these allocations, referred to as “Section 704(c) Allocations”, to a unitholder purchasing common units from us in an offering will be essentially the same as if the tax bases of our assets were equal to their fair market value at the time of such offering. In the event we issue additional common units or engage in certain other transactions in the future, “reverse Section 704(c) Allocations”, similar to the Section 704(c) Allocations described above, will be made to our general partner and persons that hold our units immediately prior to such issuance or other transactions to account for the difference between the “book” basis for purposes of maintaining capital accounts and the fair market value of all property held by us at the time of such future issuance or other transaction. In addition, items of recapture income will be allocated to the extent possible to the unitholder who was allocated the deduction giving rise to the treatment of that gain as recapture income in order to minimize the recognition of ordinary income by some unitholders. Finally, although we do not expect that our operations will result in the creation of negative capital accounts, if negative capital accounts nevertheless result, items of our income and gain will be allocated in an amount and manner sufficient to eliminate the negative balance as quickly as possible.

An allocation of items of our income, gain, loss or deduction, other than an allocation required by the Internal Revenue Code to eliminate the difference between a partner’s “book” capital account, credited with the fair market value of Adjusted Property, and “tax” capital account, credited with the tax basis of Adjusted Property, referred to in this discussion as the “Book-Tax Disparity”, will generally be given effect for federal income tax purposes in determining a partner’s share of an item of income, gain, loss or deduction only if the allocation has substantial economic effect. In any other case, a

S-22

partner’s share of an item will be determined on the basis of his interest in us, which will be determined by taking into account all the facts and circumstances, including:


	•	his relative contributions to us;

	•	the interests of all the partners in profits and losses;

	•	the interest of all the partners in cash flow; and

	•	the rights of all the partners to distributions of capital upon liquidation.

Ratio of Taxable Income to Distributions. We estimate that if you purchase common units in this offering and hold those common units through the record date for distributions with respect to the quarter ending December 31, 2011, you will be allocated, on a cumulative basis, an amount of federal taxable income for the taxable years 2009 through 2011, that will be 25% or less of the cash distributed to you with respect to such common units. This estimate is based upon many assumptions regarding our business and operations, including assumptions with respect to capital expenditures, cash flows, net working capital and anticipated cash distributions. These estimates and assumptions are subject to, among other things, numerous business, economic, regulatory, competitive and political uncertainties beyond our control. Further, the estimates are based on current tax law and tax reporting positions that we will adopt and with which the IRS could disagree. Accordingly, we cannot assure you that these estimates will prove to be correct. The actual percentage of distributions that will constitute taxable income could be higher or lower than expected, and any differences could be material and could materially affect the value of the common units. For example, the ratio of allocable taxable income to cash distributions to a purchaser of common units in this offering will be greater, and perhaps substantially greater, than our estimate with respect to the period described above if:


	•	gross income from operations exceeds the amount required to make the current level of quarterly distributions on all units, yet we only distribute the current level of quarterly distributions on all units; or

	•	we make a future offering of common units and use the proceeds of the offering in a manner that does not produce substantial additional deductions during the period described above, such as to repay indebtedness outstanding at the time of this offering or to acquire property that is not eligible for depreciation or amortization for federal income tax purposes or that is depreciable or amortizable at a rate significantly slower than the rate applicable to our assets at the time of this offering.

Tax-Exempt Organizations and Other Investors.

Ownership of common units by tax-exempt entities and non-U.S. persons raises issues unique to such persons. Such tax exempt entities or non-U.S. persons should consult an independent tax advisor before investing in our common units. Please read “Material Tax Consequences — Tax-Exempt Organizations and Other Investors” in the accompanying base prospectus.

S-23

UNDERWRITING

We and the underwriters named below have entered into an underwriting agreement with respect to the common units being offered. Subject to certain conditions, each underwriter has severally agreed to purchase the number of common units indicated in the following table. Goldman, Sachs & Co. and UBS Securities LLC are acting as the representatives of the underwriters.


	Number of
Underwriters	Common Units

Goldman, Sachs & Co.
UBS Securities LLC
SMH Capital Inc.

Total		1,900,000

The underwriters are committed to take and pay for all of the common units being offered, if any are taken, other than the common units covered by the option described below unless and until this option is exercised.

If the underwriters sell more common units than the total number set forth in the table above, the underwriters have an option to buy up to an additional 285,000 common units from us. They may exercise that option for 30 days. If any common units are purchased pursuant to this option, the underwriters will severally purchase common units in approximately the same proportion as set forth in the table above.

The following table shows the per common unit and total underwriting discounts and commissions to be paid to the underwriters by us. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase an additional 285,000 common units.


	No Exercise	Full Exercise

Per Common Unit	$	$
Total	$	$

Common units sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. Any common units sold by the underwriters to securities dealers may be sold at a discount of up to $ per common unit from the initial public offering price. If all the common units are not sold at the initial public offering price, the representatives may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

We, certain of our affiliates (including our general partner and Holly Logistic Services, L.L.C., which is the general partner of our general partner) and the officers and directors of Holly Logistic Services, L.L.C. have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any common units or securities convertible into or exchangeable for common units during the period from the date of this prospectus supplement continuing through the date 90 days after the date of this prospectus supplement, except with the prior written consent of Goldman, Sachs & Co. and UBS Securities LLC. This agreement does not apply to any existing employee benefit plans and will permit the issuance of our common units by us to Sinclair in connection with the acquisition of the Sinclair logistics assets.

In connection with the offering, the underwriters may purchase and sell common units in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of common units than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional common units from us in the offering. The underwriters may close out any covered short position by either

S-24

exercising their option to purchase additional common units or purchasing common units in the open market. In determining the source of common units to close out the covered short position, the underwriters will consider, among other things, the price of common units available for purchase in the open market as compared to the price at which they may purchase additional common units pursuant to the option granted to it. “Naked” short sales are any sales in excess of such option. The underwriters must close out any naked short position by purchasing common units in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common units in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the common units while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased common units sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts may have the effect of preventing or retarding a decline in the market price of the common units, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common units. As a result, the price of the common units may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

We estimate that our total expenses for the offering, excluding underwriting discounts and commissions, will be approximately $250,000.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the issuer, for which they received or will receive customary fees and expenses.

Because the Financial Industry Regulatory Authority (“FINRA”) views the common units offered hereby as interests in a direct participation program, the offering is being made in compliance with FINRA Rule 2310.

LEGAL MATTERS

The validity of the common units is being passed upon for us by Fulbright & Jaworski L.L.P., as our counsel. Certain legal matters are being passed upon for the underwriters by Latham & Watkins LLP.

RISK FACTORS

An investment in our securities involves risks. Before you invest in our securities you should carefully consider those risk factors included in our most recent Annual Report on Form 10-K, as supplemented by our Quarterly Reports on Form 10-Q, each of which is incorporated herein by reference, and those risk factors that may be included in the applicable prospectus supplement together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference in evaluating an investment in our securities. This prospectus also contains forward-looking statements that involve risks and uncertainties. Please read “Forward-Looking Statements.” Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risks described in the foregoing documents and the other information included in, or incorporated by reference into, this prospectus. If any of these risks occur, our business, financial condition or results of operations could be adversely affected. In that case, we may be unable to pay distributions to our untiholders, or to pay interest on, or the principal of, any debt securities. In that event, the trading price of our securities could decline and you could lose all or part of your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

FORWARD-LOOKING STATEMENTS

This prospectus and some of the documents we incorporate by reference contain various forward-looking statements and information that are based on our beliefs and those of our general partner, as well as assumptions made by and information currently available to us. These forward-looking statements are identified as any statement that does not relate strictly to historical or current facts. When used in this prospectus or the documents we have incorporated herein or therein by reference, words such as “anticipate,” “project,” “expect,” “plan,” “goal,” “forecast,” “intend,” “could,” “believe,” “may,” and similar expressions and statements regarding our plans and objectives for future operations, are intended to identify forward-looking statements. Although we and our general partner believe that such expectations reflected in such forward-looking statements are reasonable, neither we nor our general partner can give assurances that such expectations will prove to be correct. Such statements are subject to a variety of risks, uncertainties and assumptions. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those anticipated, estimated, projected or expected. Among the key risk factors that may have a direct bearing on our results of operations and financial condition are:


	•	Risks and uncertainties with respect to the actual quantities of petroleum products and crude oil shipped on our pipelines and/or terminalled in our terminals;

	•	The economic viability of those Holly Corporation subsidiaries we contract with as well as Alon USA, Inc. and our other customers;

	•	The demand for refined petroleum products in markets we serve;

	•	Our ability to successfully purchase and integrate additional operations in the future;

	•	Our ability to complete previously announced pending or contemplated acquisitions;

	•	The availability and cost of additional debt and equity financing;

	•	The possibility of reductions in production or shutdowns at refineries utilizing our pipeline and terminal facilities;

	•	The effects of current and future government regulations and policies;

	•	Our operational efficiency in carrying out routine operations and capital construction projects;

	•	The possibility of terrorist attacks and the consequences of any such attacks;

	•	General economic conditions; and

	•	Other financial, operations and legal risks and uncertainties detailed from time to time in our Securities and Exchange Commission filings.

Other factors described herein, or factors that are unknown or unpredictable, could also have a material adverse effect on future results. You should not put undue reliance on any forward-looking statements. Please review the risk factors described under “Risk Factors” in this prospectus and any prospectus supplement and in the “Risk Factors” section of our most recent Annual Report on Form 10-K and, to the extent applicable, our Quarterly Reports on Form 10-Q. Except as required by securities laws, we do not intend to update these forward-looking statements and information.

USE OF PROCEEDS

Except as otherwise provided in the applicable prospectus supplement, we will use the net proceeds from any sale of securities described in this prospectus for general partnership purposes, which may include, among other things, funding acquisitions of assets or businesses, working capital, capital expenditures, investments in subsidiaries, the retirement of existing debt and/or the repurchase of common units or other securities. The prospectus supplement for any particular offering of securities using this prospectus will disclose the actual use of the net proceeds from the sale of such securities. The exact amounts to be used and when the net proceeds will be applied to partnership purposes will depend on a number of factors, including our funding requirements and the availability of alternative funding sources.

RATIO OF EARNINGS TO FIXED CHARGES

For purposes of calculating the ratio of earnings to fixed charges, earnings represent income before income tax expense before deducting fixed charges. Fixed charges include interest and 30% of the total operating lease rental expense, which is the portion deemed to be interest. Our ratio of earnings to fixed charges for each of the periods indicated is as follows:

DESCRIPTION OF DEBT SECURITIES

Holly Energy Partners may issue debt securities in one or more series and Holly Energy Finance may be a co-issuer of one or more series of such debt securities. When used in this section, references to “we,” “us” and “our” refer to Holly Energy Partners and, if Holly Energy Finance co-issues any debt securities, Holly Energy Finance. References to an “Indenture” refer to the particular Indenture under which we issue a series of debt securities.

The following description sets forth the general terms and provisions that will apply to any of our debt securities. Each prospectus supplement will state the particular terms that will apply to any debt securities included in the supplement.

General

The Indentures

We will issue our debt securities under either a Senior Indenture or a Subordinated Indenture, among us, a trustee that we will name in the related prospectus supplement and, as applicable, any Subsidiary Guarantors. The term “Trustee” as used in this prospectus shall refer to the trustee under any Indenture. Any debt securities will be governed by the applicable provisions of the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939. We, the Trustee and, as applicable, the Subsidiary Guarantors, may enter into supplements to the applicable Indenture from time to time. The debt securities will be either senior debt securities or subordinated debt securities.

Neither Indenture contains provisions that would afford holders of debt securities protection in the event of a sudden and significant decline in our credit quality or a takeover, recapitalization or highly leveraged or

similar transaction. Accordingly, we could in the future enter into transactions that could increase the amount of indebtedness outstanding at that time or otherwise adversely affect our capital structure or credit rating.

This description is a summary of the material provisions of the debt securities and the Indentures. We urge you to read the forms of Senior Indenture and Subordinated Indenture filed as exhibits to the registration statement of which this prospectus is a part because those Indentures, and not this description, govern your rights as a holder of our debt securities.

The Debt Securities

Any series of debt securities that we issue:


	•	will be the general obligations of Holly Energy Partners and Holly Energy Finance, if Holly Energy Finance co-issues such debt securities;

	•	will be general obligations of the Subsidiary Guarantors, if guaranteed by them; and

	•	may be subordinated to our Senior Indebtedness and that of any Subsidiary Guarantors.

The Indenture does not limit the total amount of debt securities that we may issue. We may issue debt securities under the Indenture from time to time in separate series, up to the aggregate amount authorized for each such series.

Specific Terms of Each Series of Debt Securities to be Described in the Prospectus Supplement

We will prepare a prospectus supplement and either a supplemental indenture, or authorizing resolutions of the board of directors of our general partner’s general partner, accompanied by the officers’ certificate, relating to any series of debt securities that we offer, which will include specific terms relating to some or all of the following:


	•	the form and title of the debt securities;

	•	the total principal amount of the debt securities;

	•	the date or dates on which the debt securities may be issued;

	•	whether the debt securities are senior or subordinated debt securities;

	•	the currency or currencies in which principal and interest will be paid, if not in U.S. dollars;

	•	the portion of the principal amount which will be payable if the maturity of the debt securities is accelerated;

	•	any right we may have to defer payments of interest by extending the dates payments are due and whether interest on those deferred amounts will be payable;

	•	the dates on which the principal and premium, if any, of the debt securities will be payable;

	•	the interest rate or rates which the debt securities will bear, or by which the debt securities will accrete in value, and the interest payment dates for the debt securities;

	•	any conversion or exchange provisions;

	•	any optional redemption provisions;

	•	any sinking fund or other provisions that would obligate us to repurchase or otherwise redeem the debt securities;

	•	whether the debt securities are (i) to be co-issued by Holly Energy Finance and (ii) entitled to the benefits of any guarantees by the Subsidiary Guarantors;

	•	whether the debt securities may be issued in amounts other than $1,000 each or multiples thereof;

	•	any changes to or additional events of default or covenants;


	•	any changes to the defeasance or discharge provisions of the Indenture;

	•	the subordination, if any, of the debt securities and any changes to the subordination provisions of the Subordinated Indenture; and

	•	any other terms of the debt securities.

This description of debt securities will be deemed modified, amended or supplemented by any description of any series of debt securities set forth in a prospectus supplement related to that series.

The prospectus supplement also will describe any material United States federal income tax consequences or other special considerations regarding the applicable series of debt securities, including, without limitation, those relating to:


	•	debt securities with respect to which payments of principal, premium or interest are determined with reference to an index or formula, including changes in prices of particular securities, currencies or commodities;

	•	debt securities with respect to which payments of interest may be made in kind in lieu of, or in addition to, cash;

	•	debt securities with respect to which principal, premium or interest is payable in a foreign or composite currency;

	•	debt securities that are issued at a discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates; and

	•	variable rate debt securities that are exchangeable for fixed rate debt securities.

At our option, we may make cash interest payments by check mailed to the registered holders of debt securities or, if so stated in the applicable prospectus supplement, at the option of a holder by wire transfer to an account designated by the holder.

Unless otherwise provided in the applicable prospectus supplement, fully registered securities may be transferred or exchanged at the office of the Trustee at which its corporate trust business is principally administered in the United States, subject to the limitations provided in the Indenture, without the payment of any service charge, other than any applicable tax or governmental charge.

Any funds we pay to a paying agent for the payment of amounts due on any debt securities that remain unclaimed for two years will be returned to us, and the holders of the debt securities must look only to us for payment after that time.

The Subsidiary Guarantees

Our payment obligations under any series of debt securities may be jointly and severally, fully and unconditionally guaranteed by any of the Subsidiary Guarantors. If a series of debt securities is so guaranteed, the Subsidiary Guarantors will execute a notation of guarantee as further evidence of their guarantee. The applicable prospectus supplement will describe the terms of any guarantee by the Subsidiary Guarantors.

The obligations of each Subsidiary Guarantor under its guarantee of the debt securities will be limited to the maximum amount that will not result in the obligations of the Subsidiary Guarantor under the guarantee constituting a fraudulent conveyance or fraudulent transfer under federal or state law, after giving effect to:


	•	all other contingent and fixed liabilities of the Subsidiary Guarantor; and

	•	any collections from or payments made by or on behalf of any other Subsidiary Guarantors in respect of the obligations of the Subsidiary Guarantor under its guarantee.

The guarantee of any Subsidiary Guarantor may be released under certain circumstances. If we exercise our legal or covenant defeasance option with respect to debt securities of a particular series, or satisfy and discharge the Indenture with respect to that series, as described below under “Defeasance and Discharge,” then

any Subsidiary Guarantor will be released with respect to that series. Further, if no default has occurred and is continuing under the Indenture, and to the extent not otherwise prohibited by the Indenture, a Subsidiary Guarantor will be unconditionally released and discharged from its guarantee:


	•	automatically upon any sale, exchange or transfer, whether by way of merger or otherwise, to any person that is not our affiliate, of all of our direct or indirect limited partnership or other equity interests in the Subsidiary Guarantor;

	•	automatically upon the merger of the Subsidiary Guarantor into us or any other Subsidiary Guarantor or the liquidation and dissolution of the Subsidiary Guarantor; or

	•	following delivery of a written notice by us to the Trustee, upon the discharge or release of all guarantees by the Subsidiary Guarantor of any debt of ours under any credit facility, except a discharge or release by or as a result of payment under such guarantee.

If a series of debt securities is guaranteed by the Subsidiary Guarantors and is designated as subordinate to our Senior Indebtedness, then the guarantees by the Subsidiary Guarantors will be subordinated to the Senior Indebtedness of the Subsidiary Guarantors to substantially the same extent as the series is subordinated to our Senior Indebtedness. See “— Subordination.”

Specific Covenants

The prospectus supplement applicable to any particular series of debt securities will contain a description of the important financial and other covenants that apply to us and our subsidiaries that are added to the Indenture specifically for the benefit of holders of a particular series.

The Indenture will contain the following covenants for the benefit of the holders of all series of debt securities:

Reports

So long as any debt securities are outstanding, we will:


	•	for as long as we are required to file information with the Commission pursuant to the Securities and Exchange Act of 1934 (the “Exchange Act”), file with the Trustee, within 15 days after we file the same with the Commission, copies of the annual reports and of the information, documents and other reports which we are required to file with the Commission pursuant to the Exchange Act;

	•	if we are not required to file information with the Commission pursuant to the Exchange Act, file with the Trustee, within 15 days after we would have been required to file the same with the Commission, financial statements and a Management’s Discussion and Analysis of Financial Condition and Results of Operations, both comparable to what we would have been required to file with the Commission had we been subject to the reporting requirements of the Exchange Act; and

	•	if we are required to furnish annual or quarterly reports to our unitholders pursuant to the Exchange Act, file with the Trustee and mail to the holders any annual report or other reports sent to unitholders generally.

The availability to the public of the foregoing materials on the Commission’s website or on our website shall be deemed to satisfy the foregoing delivery obligations.

Merger, Consolidation or Sale of Assets

We may, without the consent of the holders of any of the debt securities, consolidate with or sell, lease, convey or otherwise dispose of all or substantially all of our assets to, or merge with or into, any partnership, limited liability company or corporation if:


	•	the entity surviving any such consolidation or merger or to which such assets shall have been transferred (the “successor”) is us or the successor is a domestic partnership, limited liability company


		or corporation and expressly assumes all of our obligations and liabilities under the Indenture and the debt securities; provided that Holly Energy Finance may not consolidate with or merge into any entity other than a domestic corporation so long as we are not a corporation;


	•	immediately after giving effect to the transaction, no default or Event of Default (as defined below) has occurred and is continuing;

	•	if we are not the continuing entity, then any Subsidiary Guarantor has confirmed that its guarantee will continue to apply to the debt securities; and

	•	we have delivered to the Trustee an officers’ certificate and an opinion of counsel, each stating that such consolidation, merger or disposition complies with the Indenture.

The successor will be substituted for us in the Indenture with the same effect as if it had been an original party to the Indenture. Thereafter, the successor may exercise the rights and powers of us under the Indenture, in our name or in its own name. If we dispose of all or substantially all of our assets, we will be released from all liabilities and obligations under the Indenture and under the debt securities except that no such release will occur in the case of a lease of all or substantially all of our assets.

Events of Default, Remedies and Default

Events of Default

Each of the following events will be an “Event of Default” under the Indenture with respect to a series of debt securities, except as set forth in any prospectus supplement:


	•	default in any payment of interest on any debt securities of that series when due that continues for 30 days;

	•	default in the payment of principal of or premium, if any, on any debt securities of that series when due at its stated maturity, upon redemption, upon required repurchase or otherwise;

	•	default in the payment of any sinking fund payment on any debt securities of that series when due;

	•	failure by us or, if the series of debt securities is guaranteed by any Subsidiary Guarantor, by such Subsidiary Guarantor, for 60 days (or 180 days in the case of a failure to deliver to the Trustee the reports described under “— Reports” above) after written notice to comply with any of the other agreements contained in the Indenture, any supplement to the Indenture or any board resolution authorizing the issuance of that series;

	•	certain events of bankruptcy, insolvency or reorganization of us or, if the series of debt securities is guaranteed by any Subsidiary Guarantor, of any such Subsidiary Guarantor that is a Significant Subsidiary Guarantor (as defined below) or any group of Subsidiary Guarantors that, taken together, would constitute a Significant Subsidiary Guarantor; or

	•	if the series of debt securities is guaranteed by any Subsidiary Guarantor:


	•	any of the guarantees ceases to be in full force and effect, except as otherwise provided in the Indenture;

	•	any of the guarantees is declared null and void in a judicial proceeding; or

	•	any Subsidiary Guarantor denies or disaffirms its obligations under the Indenture or its guarantee.

A “Significant Subsidiary Guarantor” means any Subsidiary Guarantor that would be a “significant subsidiary” as defined in Article 1, Rule 1-02 of Regulation S-X, promulgated pursuant to the Securities Act of 1933 (the “Securities Act”), as such Regulation is in effect on the date of the Indenture.

Exercise of Remedies

If an Event of Default, other than an Event of Default described in the fifth bullet point above, occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the entire principal of, premium, if any, and accrued and unpaid interest, if any, on all the debt securities of that series to be due and payable immediately.

A default under the fourth bullet point above will not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding debt securities of that series notify us and, if the series of debt securities is guaranteed by any Subsidiary Guarantor, any such Subsidiary Guarantor, of the default and such default is not cured within 60 days (or 180 days in the case of a failure to deliver to the Trustee the reports described under “— Reports” above) after receipt of notice.

If an Event of Default described in the fifth bullet point above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all outstanding debt securities of all series will become immediately due and payable without any declaration of acceleration or other act on the part of the Trustee or any holders.

The holders of a majority in principal amount of the outstanding debt securities of a series may rescind any declaration of acceleration by the Trustee or the holders with respect to the debt securities of that series but only if:


	•	rescinding the declaration of acceleration would not conflict with any judgment or decree of a court of competent jurisdiction; and

	•	all existing Events of Default have been cured or waived, other than the nonpayment of principal, premium or interest on the debt securities of that series that has become due solely by the declaration of acceleration.

If an Event of Default occurs and is continuing, the Trustee will be under no obligation, except as otherwise provided in the Indenture, to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee reasonable indemnity or security against any costs, liability or expense. No holder may pursue any remedy with respect to the Indenture or the debt securities of any series, except to enforce the right to receive payment of principal, premium, if any, or interest when due, unless:


	•	such holder has previously given the Trustee notice that an Event of Default with respect to that series is continuing;

	•	holders of at least 25% in principal amount of the outstanding debt securities of that series have requested that the Trustee pursue the remedy;

	•	such holders have offered the Trustee reasonable indemnity or security against any cost, liability or expense;

	•	the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of indemnity or security; and

	•	the holders of a majority in principal amount of the outstanding debt securities of that series have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

The holders of a majority in principal amount of the outstanding debt securities of a series have the right, subject to certain restrictions, to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any right or power conferred on the Trustee with respect to that series of debt securities. The Trustee, however, may refuse to follow any direction that:


	•	conflicts with law;

	•	is inconsistent with any provision of the Indenture;


	•	the Trustee determines is unduly prejudicial to the rights of any other holder;

	•	would involve the Trustee in personal liability.

Notice of an Event of Default

Within 30 days after the occurrence of any default (meaning an event that is, or after the notice or passage of time would be, an Event of Default) or Event of Default, we are required to give written notice to the Trustee and indicate the status of the default or Event of Default and what action we are taking or propose to take to cure it. In addition, we are required to deliver to the Trustee, within 120 days after the end of each fiscal year, a compliance certificate indicating that we have complied with all covenants contained in the Indenture or whether any default or Event of Default has occurred during the previous year.

If a default occurs and is continuing, the Trustee must mail to each holder a notice of the default by the later of 90 days after the default occurs or 30 days after the Trustee knows of the default. Except in the case of a default in the payment of principal, premium, if any, or interest with respect to any debt securities, the Trustee may withhold such notice, but only if and so long as the board of directors, the executive committee or a committee of directors or responsible officers of the Trustee in good faith determines that withholding such notice is in the interests of the holders.

Amendments and Waivers

Without the consent of any holder of debt securities affected, we, the Trustee and any Subsidiary Guarantors, as applicable, may amend or supplement the Indenture to:


	•	cure any ambiguity, omission, defect or inconsistency;

	•	convey, transfer, assign, mortgage or pledge any property to or with the Trustee;

	•	provide for the assumption by a successor of our obligations under the Indenture;

	•	add any Subsidiary Guarantor with respect to the debt securities;

	•	release Holly Energy Finance as an issuer under the Indenture under certain circumstances;

	•	change or eliminate any restriction on the payment of principal of, or premium, if any, on, any debt securities;

	•	add covenants for the benefit of the holders or surrender any right or power conferred upon us or any Subsidiary Guarantor;

	•	make any change that does not adversely affect the interests of any holder;

	•	add or appoint a successor or separate Trustee;

	•	comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act of 1939;

	•	conform the text of the Indenture or any guarantee to any provision of the Description of Debt Securities in this prospectus or any prospectus supplement, to the extent that such provision was intended to be a verbatim recitation of a provision of the Indenture or the guarantee;

	•	provide for the issuance of additional debt securities in accordance with the limitations set forth in the Indenture as of the date of the Indenture; or

	•	establish the form or terms of debt securities of any series to be issued under the Indenture.

In addition, we, the Trustee and any Subsidiary Guarantors, may amend the Indenture if the holders of a majority in principal amount of all debt securities of each series that would be affected then outstanding under such Indenture consent to it. We, the Trustee and any Subsidiary Guarantors, as applicable, may not, however,

without the consent of each holder of outstanding debt securities of each series that would be affected, amend the Indenture to:


	•	reduce the percentage in principal amount of debt securities of any series whose holders must consent to an amendment;

	•	reduce the rate of or extend the time for payment of interest on any debt securities;

	•	reduce the principal of or extend the stated maturity of any debt securities;

	•	reduce the premium payable upon the redemption of any debt securities or change the time at which any debt securities may or shall be redeemed;

	•	make any debt securities payable in other than U.S. dollars;

	•	impair the right of any holder to receive payment of premium, principal or interest with respect to such holder’s debt securities on or after the applicable due date;

	•	impair the right of any holder to institute suit for the enforcement of any payment with respect to such holder’s debt securities;

	•	in the case of any subordinated debt securities, make any changes to the subordination provisions that adversely affects any holder of such securities;

	•	release any security that has been granted in respect of the debt securities, other than in accordance with the Indenture;

	•	make any change in the amendment provisions which require each holder’s consent;

	•	make any change in the waiver provisions; or

	•	except as provided in the Indenture, release any Subsidiary Guarantor or modify the guarantee of any Subsidiary Guarantor in any manner adverse to the holders.

The consent of the holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under the Indenture requiring the consent of any holders becomes effective, we are required to mail to all holders a notice briefly describing the amendment. The failure to give, or any defect in, such notice, however, will not impair or affect the validity of the amendment.

The holders of a majority in principal amount of the outstanding debt securities of each affected series, on behalf of all such holders, and subject to certain rights of the Trustee, may waive:


	•	compliance by us or a Subsidiary Guarantor with certain restrictive provisions of the Indenture; and

	•	any past default or Event of Default under the Indenture;

	•	except that such majority of holders may not waive a default:


	•	in the payment of principal, premium or interest; or

	•	in respect of a provision that under the Indenture cannot be amended without the consent of all holders of the series of debt securities that is affected.

Defeasance and Discharge

At any time, we may terminate, with respect to debt securities of a particular series, all our obligations under such series of debt securities and the Indenture, which we call a “legal defeasance.” If we decide to make a legal defeasance, however, we may not terminate our obligations:


	•	relating to the defeasance trust;

	•	to register the transfer or exchange of the debt securities;


	•	to replace mutilated, destroyed, lost or stolen debt securities; or

	•	to maintain a registrar and paying agent in respect of the debt securities.

At any time we may also effect a “covenant defeasance,” which means we have elected to terminate our obligations under:


	•	covenants applicable to a series of debt securities, including any covenant that is added specifically for such series and is described in a prospectus supplement;

	•	the bankruptcy provisions with respect to any Significant Subsidiary Guarantor or group of Subsidiary Guarantors that, taken together, constitute a Significant Subsidiary Guarantor; and

	•	the guarantee provision described under “— Events of Default, Remedies and Notices — Events of Default” above with respect to a series of debt securities, if applicable, and any Events of Default that is added specifically for such series and described in a prospectus supplement.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, payment of the affected series of debt securities may not be accelerated because of an Event of Default with respect to that series. If we exercise our covenant defeasance option, payment of the defeased series of debt securities may not be accelerated because of an Event of Default with respect to that series specified in the fourth, fifth (with respect only to a Subsidiary Guarantor (if any)) or sixth bullet points under ‘‘— Events of Default” above or an Event of Default that is added specifically for such series and described in a prospectus supplement.

In order to exercise either defeasance option, we must:


	•	irrevocably deposit in trust with the Trustee money or certain U.S. government obligations for the payment of principal, premium, if any, and interest on the series of debt securities to redemption or stated maturity, as the case may be;

	•	comply with certain other conditions, including that no default has occurred and is continuing after the deposit in trust; and

	•	deliver to the Trustee of an opinion of counsel to the effect that holders of the series of debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, such opinion of counsel must be based on a ruling of the Internal Revenue Service or other change in applicable federal income tax law.

If we exercise either our legal defeasance option or our covenant defeasance option, any guarantee by a Subsidiary Guarantor will terminate with respect to the defeased series of debt securities.

In addition, we may satisfy and discharge all our obligations under the Indenture with respect to debt securities of a particular series, other than our obligation to register the transfer of and exchange such debt securities, provided that we either:


	•	deliver all outstanding debt securities of such series to the Trustee for cancellation; or

	•	all such debt securities not so delivered for cancellation have either become due and payable or will become due and payable at their stated maturity within one year or are called for redemption within one year, and in the case of this bullet point, we have deposited with the Trustee in trust an amount of cash sufficient to pay the entire indebtedness of such debt securities, including interest to the stated maturity or applicable redemption date.

No Personal Liability of Directors, Officers, Employees and Unitholders

No past, present or future director, officer, partner, member, employee, incorporator, manager or unitholder or other owner of any equity interest in us, our general partner or any Subsidiary Guarantors, as

applicable, will have any liability for any obligations of us or any Subsidiary Guarantors under any debt securities, any Indenture, any guarantee of any debt securities or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of any debt security accepting such debt security waives and releases all such liability. The waiver and release are part of the consideration for issuance of any debt securities and any guarantee. The waiver may not be effective to waive liabilities under the federal securities laws.

Debt securities of a series may be subordinated to our “Senior Indebtedness,” which we define generally to include any obligation created or assumed by us (or, if the series is guaranteed, any Subsidiary Guarantors) for the repayment of borrowed money and any guarantee thereof, whether outstanding or hereafter issued, unless, by the terms of the instrument creating or evidencing such obligation, it is provided that such obligation is subordinate or not superior in right of payment to the subordinated debt securities (or, if the series is guaranteed, the guarantee of any Subsidiary Guarantor), or to other obligations which are pari passu with or subordinated to the subordinated debt securities (or, if the series is guaranteed, the guarantee of any Subsidiary Guarantor). Subordinated debt securities will be subordinate in right of payment, to the extent and in the manner set forth in the Indenture and the prospectus supplement relating to such series, to the prior payment of all of our indebtedness and that of any Subsidiary Guarantor that is designated as “Senior Indebtedness” with respect to the series.

The holders of Senior Indebtedness of ours or, if applicable, any Subsidiary Guarantor, will receive payment in full of the Senior Indebtedness before holders of any subordinated debt securities will receive any payment of principal, premium or interest with respect to the subordinated debt securities upon any payment or distribution of our assets or, if applicable to any series of outstanding debt securities, the Subsidiary Guarantors’ assets, to creditors:


	•	upon a liquidation or dissolution of us or, if applicable to any series of outstanding debt securities, the Subsidiary Guarantors; or

	•	in a bankruptcy, receivership or similar proceeding relating to us or, if applicable to any series of outstanding debt securities, to the Subsidiary Guarantors.

Until the Senior Indebtedness is paid in full, any distribution to which holders of subordinated debt securities would otherwise be entitled will be made to the holders of Senior Indebtedness, except that the holders of subordinated debt securities may receive units representing limited partner interests and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the subordinated debt securities.

If we do not pay any principal, premium or interest with respect to Senior Indebtedness within any applicable grace period (including at maturity), or any other default on Senior Indebtedness occurs and the maturity of the Senior Indebtedness is accelerated in accordance with its terms, we may not:


	•	make any payments of principal, premium, if any, or interest with respect to subordinated debt securities;

	•	make any deposit for the purpose of defeasance or discharge of the subordinated debt securities; or

	•	repurchase, redeem or otherwise retire any subordinated debt securities, except that in the case of subordinated debt securities that provide for a mandatory sinking fund, we may deliver subordinated debt securities to the Trustee in satisfaction of our sinking fund obligation, unless, in any case,


	•	the default has been cured or waived and any declaration of acceleration has been rescinded;

	•	the Senior Indebtedness has been paid in full in cash; or

	•	we and the Trustee receive written notice approving the payment from the representative of each issue of “Designated Senior Indebtedness.”

During the continuance of any default, other than a default described in the immediately preceding paragraph, that may cause the maturity of any Designated Senior Indebtedness to be accelerated immediately without further notice, other than any notice required to effect such acceleration, or the expiration of any applicable grace periods, we may not pay the subordinated debt securities for a period called the “Payment Blockage Period.” Generally, “Designated Senior Indebtedness” will include:


	•	any specified issue of Senior Indebtedness of at least $100 million; and

	•	any other Senior Indebtedness that we may designate in respect of any series of subordinated debt securities.

A Payment Blockage Period will commence on the receipt by us and the Trustee of written notice of the default, called a “Blockage Notice,” from the representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and will end 179 days thereafter.

The Payment Blockage Period may be terminated before its expiration:


	•	by written notice from the person or persons who gave the Blockage Notice;

	•	by repayment in full in cash of the Designated Senior Indebtedness with respect to which the Blockage Notice was given; or

	•	if the default giving rise to the Payment Blockage Period is no longer continuing.

Unless the holders of the Designated Senior Indebtedness have accelerated the maturity of the Designated Senior Indebtedness, we may resume payments on the subordinated debt securities after the expiration of the Payment Blockage Period.

Generally, not more than one Blockage Notice may be given in any period of 360 consecutive days. The total number of days during which any one or more Payment Blockage Periods are in effect, however, may not exceed an aggregate of 179 days during any period of 360 consecutive days.

After all Senior Indebtedness is paid in full and until the subordinated debt securities are paid in full, holders of the subordinated debt securities shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness.

As a result of the subordination provisions described above, in the event of insolvency, the holders of Senior Indebtedness, as well as certain of our general creditors, may recover more, ratably, than the holders of the subordinated debt securities.

Book-Entry System

We may issue debt securities of a series in the form of one or more global certificates, each of which we refer to as a global security, registered in the name of a depositary or a nominee of a depositary. We expect that The Depository Trust Company, New York, New York, or DTC, will act as depositary. If we issue debt securities of a series in book-entry form, we will issue one or more global certificates that will be deposited with or on behalf of DTC and will not issue physical certificates to each holder. A global security may not be transferred unless it is exchanged in whole or in part for a certificated security, except that DTC, its nominees and their successors may transfer a global security as a whole to one another.

Beneficial interests in global debt securities will be shown on, and transfers of global debt securities will be made only through, records maintained by DTC and its participants.

DTC has advised us as follows:


	•	DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.


	•	DTC holds and provides asset servicing for securities that its participants (known as direct participants) deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

	•	Direct participants in DTC include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

	•	Access to the DTC system is also available to others, known as indirect participants, such as U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

	•	The rules applicable to DTC participants are on file with the Commission.

Any purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of debt securities is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners of the debt securities will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through which the beneficial owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

Because DTC can only act on behalf of direct participants, who in turn act on behalf of indirect DTC participants and certain banks, the ability of a person having a beneficial interest in a security held in DTC to transfer or pledge that interest to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of that interest, may be affected by the lack of a physical certificate of that interest. The laws of some states of the United States require that certain persons take physical delivery of securities in definitive form in order to transfer or perfect a security interest in those securities. Consequently, the ability to transfer beneficial interests in a security held in DTC to those persons may be limited.

DTC has advised us that it will take any action permitted to be taken by a holder of debt securities (including, without limitation, the presentation of debt securities for exchange) only at the direction of one or more of the participants to whose accounts with DTC interests in the relevant debt securities are credited, and only in respect of the portion of the aggregate principal amount of the debt securities as to which that participant or those participants has or have given the direction. However, in certain circumstances, DTC will exchange the global securities held by it for certificated debt securities, which it will distribute to its participants.

To facilitate subsequent transfers of ownership interests in the debt securities, all debt securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by, direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the global securities. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date (identified in the listing attached to the omnibus proxy).

All payments on the global securities will be made to Cede & Co., as holder of record, or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the Trustee on payment dates in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, us, the Trustee or any Subsidiary Guarantor, as applicable, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) shall be the responsibility of us or the Trustee. Disbursement of such payments to direct participants shall be the responsibility of DTC, and disbursement of such payments to the beneficial owners shall be the responsibility of direct and indirect participants.

Neither we, the Trustee nor any Subsidiary Guarantor, as applicable, will have any responsibility or obligation to direct or indirect participants, or the persons for whom they act as nominees, with respect to the accuracy of the records of DTC, its nominee, any other depositary or its nominee, or any participant with respect to any ownership interest in any debt securities, or payments to, or the providing of notice to participants or beneficial owners.

The Trustee

We may appoint a separate trustee for any series of debt securities. We may maintain banking and other commercial relationships with the Trustee and its affiliates in the ordinary course of business, and the Trustee may own debt securities.

Governing Law

The Indenture and any series of debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF OUR COMMON UNITS AND PREFERRED UNITS

Common Units

Our common units represent limited partner interests that entitle the holders to participate in our cash distributions and to exercise the rights and privileges available to limited partners under our partnership agreement. For a description of the relative rights and preferences of holders of common units and our general partner in and to cash distributions, please carefully review this section and the section “Cash Distribution Policy” in this prospectus.

Our outstanding common units are listed on the New York Stock Exchange, or NYSE, under the symbol “HEP.” Any additional common units we issue will also be listed on the NYSE.

The transfer agent and registrar for our common units is American Stock Transfer & Trust Company.

Number of Units

We currently have outstanding 8,390,000 common units, 7,000,000 subordinated units and 937,500 Class B subordinated units which were issued to Alon in connection with the acquisition of certain pipelines,

terminals and related assets. See “— Subordinated Units.” There is currently no established public trading market for our subordinated units or Class B subordinated units.

Status as Limited Partner or Assignee

Except as described below under “— Limited Liability,” the common units will be fully paid, and unitholders will not be required to make additional capital contributions to us.

Limited Liability

Assuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”) and that he otherwise acts in conformity with the provisions of our partnership agreement, his liability under the Delaware Act will be limited, subject to some possible exceptions, generally to the amount of capital he is obligated to contribute to us in respect of his units plus his share of any undistributed profits and assets. If it were determined, however, that the right of, or exercise of the right by, the limited partners as a group:


	•	to remove or replace our general partner;

	•	to approve some amendments to our partnership agreement; or

	•	to take other action under our partnership agreement;

constituted “participation in the control” of our business for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware to the same extent as our general partner. This liability would additionally extend to persons who transact business with us who reasonably believe that the limited partner is a general partner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. While this does not mean that a limited partner could not seek legal recourse, we know of no precedent for such a claim in Delaware case law.

Under the Delaware Act, a limited partnership may not make a distribution to a partner to the extent that at the time of the distribution, after giving effect to the distribution, all liabilities of the partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the partnership, exceed the fair value of the assets of the limited partnership.

For the purposes of determining the fair value of the assets of a limited partnership, the Delaware Act provides that the fair value of the property subject to liability of which recourse of creditors is limited shall be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act is liable to the limited partnership for the amount of the distribution for three years from the date of the distribution. Under the Delaware Act, an assignee who becomes a substituted limited partner of a limited partnership is liable for the obligations of his assignor to make contributions to the partnership, except the assignee is not obligated for liabilities unknown to him at the time he became a limited partner and that could not be ascertained from our partnership agreement.

We conduct business in seven states. We may conduct business in other states in the future. Maintenance of our limited liability as a limited partner of our operating partnership may require compliance with legal requirements in the jurisdictions in which our operating partnership conducts business, including qualifying our subsidiaries to do business there.

Limitations on the liability of limited partners for the obligations of a limited partnership have not been clearly established in many jurisdictions. If, by virtue of our limited partner interest in our operating partnership or otherwise, it were determined that we were conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right of, or exercise of the right by, the limited partners as a group, to remove or replace our general partner, to approve some amendments to our partnership agreement, or to take other action under our partnership agreement constituted

“participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then the limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

Voting Rights

Unless otherwise noted or the context otherwise requires, references in this section “— Voting Rights” to “subordinated units” include both our subordinated units and our Class B subordinated units.

Our general partner manages and operates us. Unlike the holders of common stock in a corporation, the holders of our units have only limited voting rights on matters affecting our business. They have no right to elect our general partner, or the directors of our general partner, on an annual or other continuing basis. On those matters that are submitted to a vote of unitholders, each record holder of a unit has a vote according to his percentage interest in us, although additional limited partner interests having special voting rights could be issued. However, if at any time any person or group, other than the general partner and its affiliates, or a direct or subsequently approved transferee of the general partner or its affiliates, acquires, in the aggregate, beneficial ownership of 20% or more of any class of units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes, determining the presence of a quorum, or for other similar purposes.

Unitholders will not have voting rights except with respect to the following matters which require the unitholder vote specified below. Matters requiring the approval of a “unit majority” require:


	•	during the subordination period for the subordinated units, (i) the approval of a majority of the common units, excluding those common units held by our general partner and its affiliates, and (ii) the approval of a majority of the subordinated units and Class B subordinated units voting as a single class;

	•	after the end of the subordination period for the subordinated units but prior to the end of the subordination period for the Class B subordinated units, the approval of a majority of the outstanding units; and

	•	after the end of the subordination periods for both our subordinated units and our Class B subordinated units, the approval of a majority of the outstanding units.

In voting their common and subordinated units, the general partner and its affiliates will have no fiduciary duly or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us and the limited partners.


Issuance of additional common units or units of equal rank with the common units during the subordination period		Unit majority, with certain exceptions.

Issuance of units senior to the common units during the subordination period		Unit majority.

Issuance of units junior to the common units during the subordination period		No approval rights.

Issuance of additional units after the subordination period		No approval rights.

Amendment of the partnership agreement		Certain amendments may be made by the general partner without the approval of the unitholders. Other amendments generally require the approval of a unit majority.


Merger of our partnership or the sale of all or substantially all of our assets		Unit majority.

Amendment of the partnership agreement of our operating partnership and other action taken by us as a limited partner of the operating partnership		Unit majority if such amendment or other action would adversely affect our limited partners (or any particular class of limited partners) in any material respect.

Dissolution of our partnership		Unit majority.

Reconstitution of our partnership upon dissolution		Unit majority.

Withdrawal of the general partner		Under most circumstances, the approval of a majority of the common units, excluding common units held by the general partner and its affiliates, is required for the withdrawal of the general partner prior to June 30, 2014 in a manner which would cause a dissolution of our partnership.

Removal of the general partner		Not less than 662/3% of the outstanding units, voting as a single class, including units held by our general partner and its affiliates.

Transfer of the general partner interest		Our general partner may transfer all, but not less than all, of its general partner interest in us without a vote of our unitholders to an affiliate or another person in connection with its merger or consolidation with or into, or sale of all or substantially all of its assets to such person. The approval of a majority of the common units, excluding common units held by the general partner and its affiliates, is required in other circumstances for a transfer of the general partner interest to a third party prior to June 30, 2014.

Transfer of incentive distribution rights		Except for transfers to an affiliate or another person as part of the general partner’s merger or consolidation with or into, or sale of all or substantially all of its assets to such person, the approval of a majority of the common units, excluding common units held by our general partner and its affiliates, voting separately as a class, is required in most circumstances for a transfer of the incentive distribution rights to a third party prior to June 30, 2014.

Transfer of ownership interests in the general partner		No approval required at any time.

Transfer of Common Units

The purchase of any common units offered by this prospectus and any prospectus supplement is accomplished through the completion, execution and delivery of a transfer application. Additionally, any later transfers of common units will not be recorded by the transfer agent or recognized by us unless the transferee executes and delivers a transfer application. By executing and delivering a transfer application, a purchaser or transferee of common units:


	•	becomes the record holder of the common units and is an assignee until admitted into our partnership as a substituted limited partner;

	•	automatically requests admission as a substituted limited partner in our partnership;

	•	agrees to be bound by the terms and conditions of, and executes, our partnership agreement;


	•	represents that such transferee has the capacity, power and authority to enter into the partnership agreement;

	•	grants powers of attorney to officers of our general partner and any liquidator of us as specified in the partnership agreement; and

	•	gives the consents and approvals contained in our partnership agreement.

An assignee will become a substituted limited partner of our partnership for the transferred common units upon admission by our general partner and the recording of the name of the assignee on our books and records. Our general partner intends to admit assignees as substituted limited partners on a quarterly basis.

A transferee’s broker, agent or nominee may complete, execute and deliver a transfer application. We are entitled to treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

Common units are securities and are transferable according to the laws governing transfer of securities. In addition to other rights acquired upon transfer, the transferor gives the transferee the right to request admission as a substituted limited partner in our partnership for the transferred common units. A purchaser or transferee of common units who does not execute and deliver a transfer application obtains only:


	•	the right to assign the common unit to a purchaser or other transferee; and

	•	the right to transfer the right to seek admission as a substituted limited partner in our partnership for the transferred common units.

Thus, a purchaser or transferee of common units who does not execute and deliver a transfer application:


	•	will not receive cash distributions or federal income tax allocations, unless the common units are held in a nominee or “street name” account and the nominee or broker has executed and delivered a transfer application; and may not receive some federal income tax information or reports furnished to record holders of common units.

The transferor of common units has a duty to provide the transferee with all information that may be necessary to transfer the common units. The transferor does not have a duty to insure the execution of the transfer application by the transferee and has no liability or responsibility if the transferee neglects or chooses not to execute and forward the transfer application to the transfer agent. Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

Reports and Records

As soon as practicable, but in no event later than 120 days after the close of each fiscal year, our general partner will furnish or make available to each unitholder of record (as of a record date selected by our general partner) an annual report containing our audited financial statements and a report on those financial statements by our independent public accountants. These financial statements will be prepared in accordance with generally accepted accounting principles. Except for our fourth quarter, we will also furnish or make available summary financial information within 90 days after the close of each quarter.

We will also furnish each unitholder of record with information reasonably required for tax reporting purposes within 90 days after the close of each calendar year. This information is expected to be furnished in summary form so that some complex calculations normally required of partners can be avoided. Our ability to furnish this summary information to unitholders will depend on the cooperation of unitholders in supplying us with specific information. Every unitholder will receive information to assist him in determining his federal and state tax liability and filing his federal and state income tax returns, regardless of whether he supplies us with information.

A limited partner can, for a purpose reasonably related to the limited partner’s interest as a limited partner, upon reasonable demand and at his own expense, have furnished to him:


	•	a current list of the name and last known address of each partner;

	•	a copy of our tax returns;

	•	information as to the amount of cash and a description and statement of the agreed value of any other property or services, contributed or to be contributed by each partner and the date on which each became a partner;

	•	copies of our partnership agreement, our certificate of limited partnership, amendments to either of them and powers of attorney which have been executed under our partnership agreement;

	•	information regarding the status of our business and financial condition; and

	•	any other information regarding our affairs as is just and reasonable.

Our general partner may, and intends to, keep confidential from the limited partners trade secrets and other information the disclosure of which our general partner believes in good faith is not in our best interest or which we are required by law or by agreements with third parties to keep confidential.

Subordinated Units

Our subordinated units are a separate class of limited partner interests in our partnership, and the rights of holders of subordinated units to participate in distributions to partners differ from, and are subordinated to, the rights of the holders of our common units. Our Class B subordinated units are a separate series of subordinated units and generally rank equally with our other subordinated units and are entitled to the same cash distributions and to exercise the same rights and privileges available to holders of our subordinated units, except under certain circumstances described below. During the subordination period, our subordinated units and our Class B subordinated units will not be entitled to receive any distributions until our common units have received the minimum quarterly distribution plus any arrearages from prior quarters.

The subordination period for our subordinated units will end once we meet the financial tests in the partnership agreement and as further described in the section “Cash Distribution Policy — Subordination Periods — Definition of Subordination Period,” but generally cannot end before June 30, 2009.

Our Class B subordinated units were created by Amendment No. 1 to our partnership agreement and issued to Alon USA, Inc. on February 28, 2005 as partial consideration for certain pipelines, terminals and related assets acquired by us from Alon. The Class B subordinated units rank equally with our previously existing subordinated units and receive the same cash distributions, rights and privileges as such subordinated units, except (i) the subordination period with respect to the Class B subordinated units will terminate on the first day of any quarter ending on or after March 31, 2010 if Alon has not defaulted on its minimum volume commitment payment obligations under the pipelines and terminals agreement it entered into with us, subject to certain conditions, and (ii) distributions to Alon with respect to the Class B subordinated units will be suspended if Alon defaults on its payments due us pursuant to its minimum volume commitment under the Alon pipelines and terminals agreement.

When the applicable subordination period ends, all related subordinated units will convert into common units on a one-for-one basis, and the common units will no longer be entitled to arrearages once all subordination periods have ended.

Preferred Units

Except as set forth below, our partnership agreement authorizes us to issue an unlimited number of additional limited partner interests and other equity securities for the consideration and with the rights, preferences and privileges established by our general partner in its sole discretion without the approval of any of our limited partners. In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership interests that, in the sole discretion of our general partner, have special

voting rights to which our common units are not entitled. As of the date of this prospectus, we have no preferred units outstanding.

Should we offer preferred units under this prospectus, a prospectus supplement relating to the particular series of preferred units offered will include the specific terms of those preferred units, including the following:


	•	the designation, stated value and liquidation preference of the preferred units and the number of preferred units offered;

	•	the initial public offering price at which the preferred units will be issued;

	•	the conversion or exchange provisions of the preferred units;

	•	any redemption or sinking fund provisions of the preferred units;

	•	the distribution rights of the preferred units, if any;

	•	a discussion of material federal income tax considerations, if any, regarding the preferred units; and

	•	any additional rights, preferences, privileges, limitations and restrictions of the preferred units.

As described in “Description of our Partnership Agreement — Issuance of Additional Securities”, until the expiration of the subordination period (see “Cash Distribution Policy — Subordination Period — Definition of Subordination Period”), our ability to issue preferred units is limited and requires the consent of (i) at least a majority of our outstanding common units (excluding common units held by our general partner and its affiliates) and (ii) at least a majority of our outstanding subordinated units and Class B subordinated units voting as a single class. (See also the discussion under “— Common Units — Voting Rights.”)

CASH DISTRIBUTION POLICY

Unless otherwise noted or the context otherwise requires, references in this section to “subordinated units” includes both subordinated units and Class B subordinated units of Holly Energy Partners. We have not issued any preferred units and the discussion below assumes that no preferred units are outstanding. A description of the material terms of our cash distribution policy as it applies to any preferred units will be set forth in the prospectus supplement relating to the offering of such preferred units.

Distributions of Available Cash

General. Our partnership agreement provides that we will distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter.

Definition of Available Cash. Available cash generally means, for each fiscal quarter, all cash on hand at the end of the quarter:


	•	less the amount of cash reserves established by our general partner to:


	•	provide for the proper conduct of our business;

	•	comply with applicable law, any of our debt instruments, or other agreements; or

	•	provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters;

plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under our credit facility and in all cases are used solely for working capital purposes or to pay distributions to partners.

Operating Surplus and Capital Surplus

General. All cash distributed to unitholders will be characterized as either “operating surplus” or “capital surplus.” We distribute available cash from operating surplus differently than available cash from capital surplus.

Definition of Operating Surplus. Operating surplus for any period generally means:


	•	our cash balance on the closing date of our initial public offering; plus

	•	$10.0 million (as described below); plus

	•	all of our cash receipts after the closing of our initial public offering, excluding cash from borrowings that are not working capital borrowings, sales of equity and debt securities and sales or other dispositions of assets outside the ordinary course of business; plus

	•	working capital borrowings made after the end of a quarter but before the date of determination of operating surplus for the quarter; less

	•	all of our operating expenditures after the closing of our initial public offering, including the repayment of working capital borrowings, but not the repayment of other borrowings, and including maintenance capital expenditures; less

	•	the amount of cash reserves established by our general partner to provide funds for future operating expenditures.

Definition of Capital Surplus. Generally, capital surplus will be generated only by:


	•	borrowings other than working capital borrowings;

	•	sales of debt and equity securities; and

	•	sales or other disposition of assets for cash, other than inventory, accounts receivable and other current assets sold in the ordinary course of business or as part of normal retirements or replacements of assets.

Characterization of Cash Distributions. We will treat all available cash distributed as coming from operating surplus until the sum of all available cash distributed since we began operations equals the operating surplus as of the most recent date of determination of available cash. We will treat any amount distributed in excess of operating surplus, regardless of its source, as capital surplus. As reflected above, operating surplus includes $10.0 million in addition to our cash balance on July 13, 2004, the closing date of our initial public offering, cash receipts from our operations and cash from working capital borrowings. This amount does not reflect actual cash on hand at closing that is available for distribution to our unitholders. Rather, it is a provision that will enable us, if we choose, to distribute as operating surplus up to $10.0 million of cash we receive in the future from non-operating sources, such as asset sales, issuances of securities, and long-term borrowings, that would otherwise be distributed as capital surplus.

Subordination Periods

General. During the subordination periods, the common units will have the right to receive distributions of available cash from operating surplus in an amount equal to the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. As described in the section “Description of Our Common Units — Subordinated Units,” our Class B subordinated units are subject to additional possible restrictions on cash distributions. The purpose of the subordinated units is to increase the likelihood that during the subordination period there is available cash to be distributed on the common units.

Definition of Subordination Period. The subordination period for the subordinated units commenced upon the closing of our initial public offering and generally extends until the first day of any quarter beginning after June 30, 2009, that each of the following tests are met:


	•	distributions of available cash from operating surplus on each of the outstanding common units and subordinated units equaled or exceeded the minimum quarterly distribution for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date;

	•	the adjusted operating surplus generated during each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of the minimum quarterly distributions on all of the outstanding common units and subordinated units during those periods on a fully diluted basis and the related distribution on the 2% general partner interest during those periods; and

	•	there are no arrearages in payment of the minimum quarterly distribution on the common units.

Definition of Class B Subordination Period. The subordination period for the Class B subordinated units commenced upon the issuance of the Class B subordinated units and generally extends until the first day of any quarter beginning after March 31, 2010 provided that no Alon event of default in respect of payments due under Alon’s pipelines and terminals agreement existed with respect to each of the three consecutive, non-overlapping four-quarter periods immediately preceding such date.

Definition of Adjusted Operating Surplus. Adjusted operating surplus for any period generally means:


	•	operating surplus generated with respect to that period; less

	•	any net increase in working capital borrowings with respect to that period; less

	•	any net reduction in cash reserves for operating expenditures with respect to that period not relating to an operating expenditure made with respect to that period; plus

	•	any net decrease in working capital borrowings with respect to that period; plus

	•	any net increase in cash reserves for operating expenditures with respect to that period required by any debt instrument for the repayment of principal, interest or premium.

Adjusted operating surplus is intended to reflect the cash generated from operations during a particular period and therefore excludes net increases in working capital borrowings and net drawdowns of reserves of cash generated in prior periods.

Effect of Expiration of the Subordination Period. Upon expiration of the applicable subordination period, each outstanding subordinated unit or Class B subordinated unit, as the case may be, will convert into one common unit and will then participate pro rata with the other common units in distributions of available cash. In addition, if the unitholders remove our general partner other than for cause and units held by the general partner and its affiliates are not voted in favor of such removal:


	•	the subordination period for our subordinated units and our Class B subordinated units will end and each subordinated unit and Class B subordinated unit will immediately convert into one common unit;

	•	any existing arrearages in payment of the minimum quarterly distribution on the common units will be extinguished; and

	•	the general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests.

Distributions of Available Cash from Operating Surplus during the Subordination Periods

We make distributions of available cash from operating surplus for any quarter during the subordination periods in the following manner:


	•	First, 98% to the common unitholders, pro rata, and 2% to the general partner, until we distribute for each outstanding common unit an amount equal to the minimum quarterly distribution for that quarter;

	•	Second, 98% to the common unitholders, pro rata, and 2% to the general partner, until we distribute for each outstanding common unit an amount equal to any arrearages in payment of the minimum quarterly distribution on the common units for any prior quarters during the subordination period;

	•	Third, 98% to the subordinated unitholders and the Class B subordinated unitholders, pro rata, and 2% to the general partner, until we distribute for each subordinated unit and Class B subordinated unit an amount equal to the minimum quarterly distribution for that quarter; and

	•	Thereafter, in the manner described in “— Incentive Distribution Rights” below;

provided, however, that distributions on the Class B subordinated units may be suspended or reduced if Alon defaults on its payments due us pursuant to its minimum volume commitment under the Alon pipelines and terminals agreement.

Distributions of Available Cash from Operating Surplus after the Subordination Period

We make distributions of available cash from operating surplus for any quarter after the subordination period in the following manner:


	•	First, 98% to all unitholders, pro rata, and 2% to the general partner, until we distribute for each outstanding unit an amount equal to the minimum quarterly distribution for that quarter; and

	•	Thereafter, in the manner described in “— Incentive Distribution Rights” below.

Incentive Distribution Rights

Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Our general partner currently holds the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in the partnership agreement.

If for any quarter:


	•	we have distributed available cash from operating surplus to the common and subordinated unitholders in an amount equal to the minimum quarterly distribution; and

	•	we have distributed available cash from operating surplus on outstanding common units in an amount necessary to eliminate any cumulative arrearages in payment of the minimum quarterly distribution;

then, we will distribute any additional available cash from operating surplus for that quarter among the unitholders and the general partner in the following manner:


	•	First, 98% to all unitholders, pro rata, and 2% to the general partner, until each unitholder receives a total of $0.55 per unit for that quarter (the “first target distribution”);

	•	Second, 85% to all unitholders, pro rata, and 15% to the general partner, until each unitholder receives a total of $0.625 per unit for that quarter (the “second target distribution”);

	•	Third, 75% to all unitholders, pro rata, and 25% to the general partner, until each unitholder receives a total of $0.75 per unit for that quarter (the “third target distribution”); and

	•	Thereafter, 50% to all unitholders, pro rata, and 50% to the general partner.

In each case, the amount of the target distribution set forth above is exclusive of any distributions to common unitholders to eliminate any cumulative arrearages in payment of the minimum quarterly distribution. The percentage interests set forth above for our general partner include its 2% general partner interest and assume the general partner has not transferred its incentive distribution rights.

Percentage Allocations of Available Cash from Operating Surplus

The following table illustrates the percentage allocations of the additional available cash from operating surplus between the unitholders and our general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution,” until available cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for the unitholders and the general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner include its 2% general partner interest and assume the general partner has not transferred its incentive distribution rights.


	Total Quarterly	Marginal Percentage Interest
	Distribution	in Distributions
	Target Amount	Unitholders			General Partner

Minimum Quarterly Distribution	$0.50		98	%		2	%
First Target Distribution	up to $0.55		98	%		2	%
Second Target Distribution	above $0.55 up to $0.625		85	%		15	%
Third Target Distribution	above $0.625 up to $0.75		75	%		25	%
Thereafter	above $0.75		50	%		50	%

Distributions from Capital Surplus

How Distributions from Capital Surplus Are Made. We will make distributions of available cash from capital surplus, if any, in the following manner:


	•	First, 98% to all unitholders, pro rata, and 2% to the general partner, until we distribute for each common unit, an amount of available cash from capital surplus equal to the initial public offering price;

	•	Second, 98% to the common unitholders, pro rata, and 2% to the general partner, until we distribute for each common unit, an amount of available cash from capital surplus equal to any unpaid arrearages in payment of the minimum quarterly distribution on the common units; and

	•	Thereafter, we will make all distributions of available cash from capital surplus as if they were from operating surplus.

Effect of a Distribution from Capital Surplus. The partnership agreement treats a distribution of capital surplus as the repayment of the initial unit price from our initial public offering, which is a return of capital. The initial public offering price less any distributions of capital surplus per unit is referred to as the “unrecovered initial unit price.” Each time a distribution of capital surplus is made, the minimum quarterly distribution and the target distribution levels are reduced in the same proportion as the corresponding reduction in the unrecovered initial unit price. Because distributions of capital surplus will reduce the minimum quarterly distribution, after any of these distributions are made, it may be easier for the general partner to receive incentive distributions and for the subordinated units to convert into common units. However, any distribution of capital surplus before the unrecovered initial unit price is reduced to zero cannot be applied to the payment of the minimum quarterly distribution or any arrearages.

Once we distribute capital surplus on a unit equal to the initial unit price, we will reduce the minimum quarterly distribution and the target distribution levels to zero. We will then make all future distributions from operating surplus, with 50% being paid to the holders of units and 50% to the general partner. The percentage

interests shown for our general partner include its 2% general partner interest and assume the general partner has not transferred the incentive distribution rights.

Adjustment to the Minimum Quarterly Distribution and Target Distribution Levels

In addition to adjusting the minimum quarterly distribution and target distribution levels to reflect a distribution of capital surplus, if we combine our units into fewer units or subdivide our units into a greater number of units, we will proportionately adjust:


	•	the minimum quarterly distribution;

	•	target distribution levels;

	•	the unrecovered initial unit price;

	•	the number of common units issuable during the subordination period without a unitholder vote; and

	•	the number of common units into which a subordinated unit is convertible.

For example, if a two-for-one split of the common units should occur, the minimum quarterly distribution, the target distribution levels and the unrecovered initial unit price would each be reduced to 50% of its initial level, the number of common units issuable during the subordination period without unitholder vote would double and each subordinated unit would be convertible into two common units. We will not make any adjustment by reason of the issuance of additional units for cash or property.

In addition, if legislation is enacted or if existing law is modified or interpreted by a governmental taxing authority, so that we become taxable as a corporation or otherwise subject to taxation as an entity for federal, state or local income tax purposes, we will reduce the minimum quarterly distribution and the target distribution levels for each quarter by multiplying each distribution level by a fraction, the numerator of which is available cash for that quarter and the denominator of which is the sum of available cash for that quarter plus the general partner’s estimate of our aggregate liability for the quarter for such income taxes payable by reason of such legislation or interpretation. To the extent that the actual tax liability differs from the estimated tax liability for any quarter, the difference will be accounted for in subsequent quarters.

Distributions of Cash Upon Liquidation

General. If we dissolve in accordance with the partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders and the general partner, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

The allocations of gain and loss upon liquidation are intended, to the extent possible, to entitle the holders of outstanding common units to a preference over the holders of outstanding subordinated units upon our liquidation, to the extent required to permit common unitholders to receive their unrecovered initial unit price plus the minimum quarterly distribution for the quarter during which liquidation occurs plus any unpaid arrearages in payment of the minimum quarterly distribution on the common units. However, there may not be sufficient gain upon our liquidation to enable the holders of common units to fully recover all of these amounts, even though there may be cash available for distribution to the holders of subordinated units. Any further net gain recognized upon liquidation will be allocated in a manner that takes into account the incentive distribution rights of the general partner.

Manner of Adjustments for Gain. The manner of the adjustment for gain is set forth in the partnership agreement. If our liquidation occurs before the end of the subordination period, we will allocate any gain to the partners in the following manner:


	•	First, to the general partner and the holders of units who have negative balances in their capital accounts to the extent of and in proportion to those negative balances;


	•	Second, 98% to the common unitholders, pro rata, and 2% to the general partner, until the capital account for each common unit is equal to the sum of: (1) the unrecovered initial unit price; (2) the amount of the minimum quarterly distribution for the quarter during which our liquidation occurs; and (3) any unpaid arrearages in payment of the minimum quarterly distribution;

	•	Third, 98% to the subordinated unitholders, pro rata, and 2% to the general partner until the capital account for each subordinated unit is equal to the sum of: (1) the unrecovered initial unit price; and (2) the amount of the minimum quarterly distribution for the quarter during which our liquidation occurs;

	•	Fourth, 98% to all unitholders, pro rata, and 2% to the general partner, until we allocate under this paragraph an amount per unit equal to: (1) the sum of the excess of the first target distribution per unit over the minimum quarterly distribution per unit for each quarter of our existence; less (2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the minimum quarterly distribution per unit that we distributed 98% to the unitholders, pro rata, and 2% to the general partner, for each quarter of our existence;

	•	Fifth, 85% to all unitholders, pro rata, and 15% to the general partner, until we allocate under this paragraph an amount per unit equal to: (1) the sum of the excess of the second target distribution per unit over the first target distribution per unit for each quarter of our existence; less (2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the first target distribution per unit that we distributed 85% to the unitholders, pro rata, and 15% to the general partner for each quarter of our existence;

	•	Sixth, 75% to all unitholders, pro rata, and 25% to the general partner, until we allocate under this paragraph an amount per unit equal to: (1) the sum of the excess of the third target distribution per unit over the second target distribution per unit for each quarter of our existence; less (2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the second target distribution per unit that we distributed 75% to the unitholders, pro rata, and 25% to the general partner for each quarter of our existence; and

	•	Thereafter, 50% to all unitholders, pro rata, and 50% to the general partner.

The percentage interests set forth above for our general partner include its 2% general partner interest and assume the general partner has not transferred the incentive distribution rights.

If the liquidation occurs after the end of the subordination period, the distinction between common units and subordinated units will disappear, so that clause (3) of the second bullet point above and all of the third bullet point above will no longer be applicable.

Manner of Adjustments for Losses. If our liquidation occurs before the end of the subordination period, we will generally allocate any loss to the general partner and the unitholders in the following manner:


	•	First, 98% to holders of subordinated units in proportion to the positive balances in their capital accounts and 2% to the general partner, until the capital accounts of the subordinated unitholders have been reduced to zero;

	•	Second, 98% to the holders of common units in proportion to the positive balances in their capital accounts and 2% to the general partner, until the capital accounts of the common unitholders have been reduced to zero; and

	•	Thereafter, 100% to the general partner.

If the liquidation occurs after the end of the subordination period, the distinction between common units and subordinated units will disappear, so that all of the first bullet point above will no longer be applicable.

Adjustments to Capital Accounts. We will make adjustments to capital accounts upon the issuance of additional units. In doing so, we will allocate any unrealized and, for tax purposes, unrecognized gain or loss resulting from the adjustments to the unitholders and the general partner in the same manner as we allocate

gain or loss upon liquidation. In the event that we make positive adjustments to the capital accounts upon the issuance of additional units, we will allocate any later negative adjustments to the capital accounts resulting from the issuance of additional units or upon our liquidation in a manner which results, to the extent possible, in the general partner’s capital account balances equaling the amount which they would have been if no earlier positive adjustments to the capital accounts had been made.

DESCRIPTION OF OUR PARTNERSHIP AGREEMENT

The following is a summary of the material provisions of our partnership agreement. Our amended and restated partnership agreement, as amended, has been filed with the Commission. The following provisions of our partnership agreement are summarized elsewhere in this prospectus:


	•	distributions of our available cash are described under “Cash Distribution Policy”;

	•	allocations of taxable income and other matters are described under “Material Tax Consequences”;

	•	rights of holders of common units are described under “Description of Our Common Units”; and

	•	fiduciary duties of our general partner are described under “Conflicts of Interest and Fiduciary Duties.”

Unless otherwise noted, references in this “Description of Our Partnership Agreement” to “subordinated units” include both of Holly Energy Partners’ subordinated units and Class B subordinated units.

Purpose

Our purpose under our partnership agreement is to serve as the limited partner of our operating partnership and to engage in any business activities that may be engaged in by our operating partnership or that are approved by our general partner. The partnership agreement of our operating partnership provides that the operating partnership may, directly or indirectly, engage in (i) its operations as conducted immediately before our initial public offering, (ii) any other activity approved by the general partner but only to the extent that the general partner determines that, as of the date of the acquisition or commencement of the activity, the activity generates “qualifying income” as this term is defined in Section 7704 of the Internal Revenue Code, or (iii) any activity that enhances the operations of an activity that is described in clause (i) or (ii).

Power of Attorney

Each limited partner, and each person who acquires a unit from a unitholder and executes and delivers a transfer application, grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution. The power of attorney also grants the authority for the amendment of, and to make consents and waivers under, our partnership agreement.

Reimbursements of Our General Partner

Our general partner does not receive any compensation for its services as our general partner. It is, however, entitled to be reimbursed for all of its costs incurred in managing and operating our business. Our partnership agreement provides that our general partner will determine the expenses that are allocable to us in any reasonable manner determined by our general partner in its sole discretion.

Issuance of Additional Securities

Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and rights to buy partnership securities for the consideration and on the terms and conditions determined by our general partner in its sole discretion without the approval of the unitholders. During the subordination periods, however, except as we discuss in the following paragraph, we may not issue equity securities ranking senior to the common units or an aggregate of more than 3,500,000 additional common units or units on a parity with the common units, in each case, without the approval of the holders of a unit majority.

During or after the subordination period, we may issue an unlimited number of common units as follows:


	•	upon conversion of the subordinated units;

	•	under employee benefit plans;

	•	upon conversion of the general partner interest and incentive distribution rights as a result of a withdrawal or removal of the general partner;

	•	in connection with the conversion of units of equal rank with the common units into common units under certain circumstances;

	•	in the event of a combination or subdivision of common units;

	•	in connection with an acquisition or a capital improvement that increases cash flow from operations per unit on an estimated pro forma basis;

	•	if the proceeds of the issuance are used to repay indebtedness the cost of which to service is greater than the distribution obligations associated with the units issued in connection with the debt’s retirement; or

	•	in connection with the redemption of common units if the net proceeds from the issuance of the new common units are used to redeem an equal number of common units outstanding at the time of such issuance, at a price per unit equal to the net proceeds per newly issued common unit, before expenses.

It is possible that we will fund acquisitions through the issuance of additional common units, subordinated units, Class B subordinated units or other equity securities. Holders of any additional common units, subordinated units, Class B subordinated units or other equity securities we issue may be entitled to share equally with the then-existing holders of such common units, subordinated units, Class B subordinated units or other equity securities in our cash distributions. In addition, the issuance of additional partnership interests may dilute the value of the interests of the then-existing holders of common units in our net assets.

In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership interests that, in the sole discretion of our general partner, may have special voting rights to which common units are not entitled.

Upon issuance of additional partnership securities, the general partner will be required to make additional capital contributions to the extent necessary to maintain its 2% general partner interest in us. Moreover, the general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase common units, subordinated units or other equity securities whenever, and on the same terms that, we issue those securities to persons other than the general partner and its affiliates, to the extent necessary to maintain its and its affiliates percentage interest, including its interest represented by common units and subordinated units, that existed immediately prior to each issuance. The holders of common units do not have preemptive rights to acquire additional common units or other partnership securities.

Amendments to Our Partnership Agreement

Amendments to our partnership agreement may be proposed only by, or with the consent of, our general partner, which consent may be given or withheld at its option, except as set forth in our partnership agreement. Any amendment that materially and adversely affects the rights or preferences of any type or class of limited partner interests in relation to other types or classes of limited partner interests or our general partner interest will require the approval of at least a majority of the type or class of limited partner interests or general partner interests so affected. However, in some circumstances, more particularly described in our partnership agreement, our general partner may make amendments to our partnership agreement without the approval of our limited partners or assignees.

Withdrawal or Removal of Our General Partner

Except as described below, our general partner has agreed not to withdraw voluntarily as our general partner prior to June 30, 2014 without obtaining the approval of the holders of at least a majority of the outstanding common units, excluding common units held by the general partner and its affiliates, and furnishing an opinion of counsel regarding limited liability and tax matters. On or after June 30, 2014, our general partner may withdraw as general partner without first obtaining approval of any unitholder by giving 90 days’ written notice, and that withdrawal will not constitute a violation of the partnership agreement. Notwithstanding the information above, our general partner may withdraw without unitholder approval upon 90 days’ notice to the limited partners if at least 50% of the outstanding common units are held or controlled by one person and its affiliates other than the general partner and its affiliates. In addition, the partnership agreement permits our general partner in some instances to sell or otherwise transfer all of its general partner interest in us without the approval of the unitholders.

Upon withdrawal of our general partner under any circumstances, other than as a result of a transfer by the general partner of all or a part of its general partner interest in us, the holders of a majority of the outstanding common units and subordinated units, voting as separate classes, may select a successor to that withdrawing general partner. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability and tax matters cannot be obtained, we will be dissolved, wound up, and liquidated, unless within a specified period of time after that withdrawal, the holders of a unit majority agree in writing to continue our business and to appoint a successor general partner.

Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 662/3% of our outstanding units, voting together as a single class, including units held by the general partner and its affiliates, and we receive an opinion of counsel regarding limited liability and tax matters. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding common units and subordinated units, voting as separate classes.

Our partnership agreement also provides that if our general partner is removed as our general partner under circumstances where cause does not exist and units held by the general partner and its affiliates are not voted in favor of that removal:


	•	the subordination period will end and all outstanding subordinated units will immediately convert into common units on a one-for-one basis;

	•	any existing arrearages in payment of the minimum quarterly distribution on the common units will be extinguished; and

	•	the general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests based on the fair market value of the interests at the time.

In the event of removal of our general partner under circumstances where cause exists or withdrawal of the general partner where that withdrawal violates the partnership agreement, a successor general partner will have the option to purchase the general partner interest and incentive distribution rights of the departing general partner for a cash payment equal to the fair market value of those interests. Under all other circumstances where the general partner withdraws or is removed by the limited partners, the departing general partner will have the option to require the successor general partner to purchase the general partner interest of the departing general partner and its incentive distribution rights for their fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner’s general partner interest and its incentive distribution rights will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, all employee-related liabilities, including severance liabilities, incurred for the termination of any employees employed by the departing general partner or its affiliates for our benefit.

Liquidation and Distribution of Proceeds

Upon our dissolution, unless we are reconstituted and continued as a new limited partnership, the person authorized to wind up our affairs (the liquidator) will, acting with all the powers of our general partner that the liquidator deems necessary or desirable in its good faith judgment, liquidate our assets and apply the proceeds of the liquidation as provided in “Cash Distribution Policy — Distributions of Cash Upon Liquidation.” The liquidator may defer liquidation or distribution of our assets for a reasonable period or distribute assets to partners in kind if it determines that a sale would be impractical or would cause undue loss to the partners.

Transfer of General Partner Interests

Except for transfer by our general partner of all, but not less than all, of its general partner interest in us to:


	•	an affiliate of the general partner (other than an individual), or

	•	another entity as part of the merger or consolidation of the general partner with or into another entity or the transfer by the general partner of all or substantially all of its assets to another entity,

our general partner may not transfer all or any part of its general partner interest in us to another person prior to June 30, 2014 without the approval of the holders of at least a majority of the outstanding common units, excluding common units held by the general partner and its affiliates. As a condition of this transfer, the transferee must, among other things, assume the rights and duties of the general partner, agree to be bound by the provisions of the partnership agreement, and furnish an opinion of counsel regarding limited liability and tax matters.

Our general partner and its affiliates may at any time transfer units to one or more persons, without unitholder approval, except that they may not transfer subordinated units to us.

Transfer of Ownership Interests in Our General Partner and in Holly Logistic Services, L.L.C.

At any time, the partners of our general partner and the members of Holly Logistic Services, L.L.C. may sell or transfer all or part of their respective partnership or membership interests in our general partner or Holly Logistic Services, L.L.C. to an affiliate or a third party without the approval of our unitholders.

Transfer of Incentive Distribution Rights

Our general partner or its affiliates or a subsequent holder may transfer its incentive distribution rights to an affiliate of the holder (other than an individual) or another entity as part of the merger or consolidation of such holder with or into another entity, or sale of all or substantially all of its assets to, that entity without the prior approval of the unitholders. Prior to June 30, 2014, other transfers of the incentive distribution rights will require the affirmative vote of holders of a majority of the outstanding common units excluding common units held by the general partner and its affiliates. On or after June 30, 2014, the incentive distribution rights will be freely transferable.

Change of Management Provisions

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove HEP Logistics Holdings, L.P. as our general partner or otherwise change management. If any person or group other than the general partner and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from our general partner or its affiliates and any transferees of that person or group approved by our general partner or to any person or group who acquires the units with the prior approval of the board of directors.

The partnership agreement also provides that if the general partner is removed under circumstances where cause does not exist and units held by the general partner and its affiliates are not voted in favor of that removal:


	•	the subordination period will end and all outstanding subordinated units will immediately convert into common units on a one-for-one basis;

	•	any existing arrearages in payment of the minimum quarterly distribution on the common units will be extinguished; and

	•	the general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests.

Limited Call Right

If at any time the general partner and its affiliates hold more than 80% of the then-issued and outstanding partnership securities of any class, the general partner will have the right, which it may assign in whole or in part to any of its affiliates or to us, to acquire all, but not less than all, of the remaining partnership securities of the class held by unaffiliated persons as of a record date to be selected by the general partner, on at least ten but not more than 60 days notice. The purchase price in the event of this purchase is the greater of: (1) the highest cash price paid by either of the general partner or any of its affiliates for any partnership securities of the class purchased within the 90 days preceding the date on which the general partner first mails notice of its election to purchase those partnership securities; and (2) the current market price as of the date three days before the date the notice is mailed.

As a result of the general partner’s right to purchase outstanding partnership securities, a holder of partnership securities may have his partnership securities purchased at an undesirable time or price. The tax consequences to a unitholder of the exercise of this call right are the same as a sale by that unitholder of his common units in the market. Please read “Material Tax Consequences — Disposition of Common Units.”

Indemnification

Under our partnership agreement, in most circumstances, we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages, or similar events:


	•	our general partner;

	•	the general partner of our general partner;

	•	any departing general partner;

	•	any person who is or was an affiliate of our general partner or the general partner of our general partner or any departing general partner;

	•	any person who is or was a member, partner, officer, director, fiduciary or trustee of any entity described above;


	•	any person who is or was serving as a director, officer, member, partner, fiduciary or trustee of another person at the request of our general partner, the general partner of our general partner or any departing general partner; or

	•	any person designated by our general partner.

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, the general partner will not be personally liable for, or have any obligation to contribute or loan funds or assets to us to enable us to effectuate, indemnification. We may purchase insurance against liabilities asserted against and expenses incurred by persons for our activities, regardless of whether we would have the power to indemnify the person against liabilities under the partnership agreement.

Registration Rights

Under our partnership agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any common units, subordinated units or other partnership securities proposed to be sold by our general partner or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available. These registration rights continue for two years following any withdrawal or removal of HEP Logistics Holdings, L.P. as our general partner. We are obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

CONFLICTS OF INTEREST AND FIDUCIARY DUTIES

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its affiliates, including Holly Corporation, on the one hand, and us and our limited partners, on the other hand. The directors and officers of the general partner of our general partner, Holly Logistic Services, L.L.C., have fiduciary duties to manage the general partner in a manner beneficial to its owners. At the same time, our general partner has a fiduciary duty to manage us in a manner beneficial to us and our unitholders.

Whenever a conflict arises between our general partner or its affiliates, on the one hand, and us or any other partner, on the other, our general partner will resolve that conflict. Our partnership agreement contains provisions that modify and limit our general partner’s fiduciary duties to the unitholders. Our partnership agreement also restricts the remedies available to unitholders for actions taken that, without those limitations, might constitute breaches of fiduciary duty.

Our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or our unitholders if the resolution of the conflict is:


	•	approved by the conflicts committee, although our general partner is not obligated to seek such approval;

	•	approved by the vote of a majority of the outstanding common units, excluding any common units owned by our general partner or any of its affiliates;

	•	on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or

	•	fair and reasonable to us, taking into account the totality of the relationships between the parties involved, including other transactions that may be particularly favorable or advantageous to us.

Our general partner may, but is not required to, seek the approval of such resolution from the conflicts committee of the board of directors of Holly Logistic Services, L.L.C. If our general partner does not seek approval from the conflicts committee and the board of directors of Holly Logistic Services, L.L.C. determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the third and fourth bullet points above, then the resolution or course of action taken by the general partner will be permitted and deemed approved by the unitholders and will not constitute a breach

of its obligations under the partnership agreement or its duties to us or the unitholders. Unless the resolution of a conflict is specifically provided for in our partnership agreement, our general partner or the conflicts committee may consider any factors it determines in good faith to consider when resolving a conflict. When our partnership agreement requires someone to act in good faith, it requires that person to reasonably believe that he is acting in the best interests of the partnership, unless the context otherwise requires.

Conflicts of interest could arise in the situations described below, among others.

Actions taken by our general partner may affect the amount of cash available for distribution to unitholders or accelerate the right to convert subordinated units.

The amount of cash that is available for distribution to unitholders is affected by decisions of our general partner regarding such matters as:


	•	amount and timing of asset purchases and sales;

	•	cash expenditures;

	•	borrowings;

	•	issuance of additional units; and

	•	the creation, reduction, or increase of reserves in any quarter.

In addition, borrowings by us and our affiliates do not constitute a breach of any duty owed by the general partner to our unitholders, including borrowings that have the purpose or effect of:


	•	enabling our general partner or its affiliates to receive distributions on any subordinated units held by them or the incentive distribution rights; or

	•	hastening the expiration of the subordination period.

For example, in the event we have not generated sufficient cash from our operations to pay the minimum quarterly distribution on our common units and our subordinated units, our partnership agreement permits us to borrow funds, which would enable us to make this distribution on all outstanding units.

Our partnership agreement provides that we and our subsidiaries may borrow funds from our general partner and its affiliates. Our general partner and its affiliates may not borrow funds from us, our operating partnership, or its operating subsidiaries, other than in connection with Holly Corporation’s centralized cash management program.

We do not have any officers or employees and rely solely on officers and employees of Holly Logistic Services, L.L.C. and its affiliates.

Affiliates of Holly Logistic Services, L.L.C. conduct businesses and activities of their own in which we have no economic interest. If these separate activities are significantly greater than our activities, there could be material competition for the time and effort of the officers and employees who provide services to Holly Logistic Services, L.L.C. Most of the officers of Holly Logistic Services, L.L.C. are not required to work full time on our affairs. These officers are required to devote time to the affairs of Holly Corporation or its affiliates and are compensated by them for the services rendered to them.

We will reimburse the general partner and its affiliates for expenses.

We will reimburse the general partner and its affiliates for costs incurred in managing and operating us, including costs incurred in rendering corporate staff and support services to us. Our partnership agreement provides that the general partner will determine the expenses that are allocable to us in good faith.

Our general partner intends to limit its liability regarding our obligations.

Our general partner intends to limit its liability under contractual arrangements so that the other party has recourse only to our assets and not against the general partner or its assets or any affiliate of the general partner or its assets. Our partnership agreement provides that any action taken by our general partner to limit its or our liability is not a breach of the general partner’s fiduciary duties, even if we could have obtained terms that are more favorable without the limitation on liability.

Unitholders will have no right to enforce obligations of our general partner and its affiliates under agreements with us.

Any agreements between us, on the one hand, and our general partner and its affiliates, on the other, will not grant to the unitholders, separate and apart from us, the right to enforce the obligations of our general partner and its affiliates in our favor.

Contracts between us, on the one hand, and our general partner and its affiliates, on the other, will not be the result of arm’s-length negotiations.

Our partnership agreement allows our general partner to determine, in good faith, any amounts to pay itself or its affiliates for any services rendered to us. Our general partner may also enter into additional contractual arrangements with any of its affiliates on our behalf. Neither our partnership agreement nor any of the other agreements, contracts, and arrangements between us and the general partner and its affiliates are or will be the result of arm’s-length negotiations. However, any of these transactions are to be on terms that are fair and reasonable to us.

Our general partner and its affiliates will have no obligation to permit us to use any facilities or assets of the general partner and its affiliates, except as may be provided in contracts entered into specifically dealing with that use. There is no obligation of our general partner and its affiliates to enter into any contracts of this kind.

Our units are subject to our general partner’s limited call right.

Our general partner may exercise its right to call and purchase our units as provided in the partnership agreement or assign this right to one of its affiliates or to us. Our general partner may use its own discretion, free of fiduciary duty restrictions, in determining whether to exercise this right. As a result, a common unitholder may have his common units purchased from him at an undesirable time or price.

We may not choose to retain separate counsel for ourselves or for unitholders.

The attorneys, independent accountants, and others who perform services for us have been retained by our general partner. Attorneys, independent accountants, and others who perform services for us are selected by our general partner or the conflicts committee and may perform services for our general partner and its affiliates. We may retain separate counsel for ourselves or the unitholders in the event of a conflict of interest between our general partner and its affiliates, on the one hand, and us or the unitholders, on the other, depending on the nature of the conflict. We do not intend to do so in most cases.

Our general partner’s affiliates may compete with us.

Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other than those incidental to its ownership of interests in us and certain services the employees of our general partner are currently providing to Holly Corporation and its affiliates. Except as provided in our partnership agreement and the omnibus agreement among us, Holly Corporation and our general partner, affiliates of our general partner are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us.

Fiduciary Duties

Our general partner is accountable to us and our unitholders as a fiduciary. Fiduciary duties owed to unitholders by our general partner are prescribed by law and the partnership agreement. The Delaware Revised Uniform Limited Partnership Act, which we refer to in this prospectus as the Delaware Act, provides that Delaware limited partnerships may, in their partnership agreements, restrict or expand the fiduciary duties owed by a general partner to limited partners and the partnership.

Our partnership agreement contains various provisions restricting the fiduciary duties that might otherwise be owed by our general partner. These modifications are detrimental to the unitholders because they restrict the remedies available to unitholders for actions that, without those limitations, might constitute breaches of fiduciary duty, as described below. The following is a summary of the material restrictions of the fiduciary duties owed by our general partner to the limited partners:


State law fiduciary duty standards		Fiduciary duties are generally considered to include an obligation to act in good faith and with due care and loyalty. The duty of care, in the absence of a provision in a partnership agreement providing otherwise, would generally require a general partner to act for the partnership in the same manner as a prudent person would act on his own behalf. The duty of loyalty, in the absence of a provision in a partnership agreement providing otherwise, would generally prohibit a general partner of a Delaware limited partnership from taking any action or engaging in any transaction where a conflict of interest is present.

		The Delaware Act generally provides that a limited partner may institute legal action on behalf of the partnership to recover damages from a third party where a general partner has refused to institute the action or where an effort to cause a general partner to do so is not likely to succeed. In addition, the statutory or case law of some jurisdictions may permit a limited partner to institute legal action on behalf of himself and all other similarly situated limited partners to recover damages from a general partner for violations of its fiduciary duties to the limited partners.

Partnership agreement modified standards		Our partnership agreement contains provisions that waive or consent to conduct by our general partner and its affiliates that might otherwise raise issues as to compliance with fiduciary duties or applicable law. For example, our partnership agreement provides that when our general partner is acting in its capacity as our general partner, as opposed to in its individual capacity, it must act in “good faith” and will not be subject to any other standard under applicable law. In addition, when our general partner is acting in its individual capacity, as opposed to in its capacity as our general partner, it may act without any fiduciary obligation to us or the unitholders whatsoever. These standards reduce the obligations to which the general partner would otherwise be held.

		Our partnership agreement generally provides that affiliated transactions and resolutions of conflicts of interest not involving a vote of unitholders and that are not approved by the conflicts committee of the board of directors of our general partner’s general partner must be:

		• on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or


		• “fair and reasonable” to us, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to us).

		If our general partner does not seek approval from the conflicts committee and the board of directors of our general partner’s general partner determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the bullet points above, then the resolution or course of action taken by the general partner will be permitted and deemed approved by the unitholders and will not constitute a breach of its obligations under the partnership agreement or its duties to us or the unitholders. These standards reduce the obligations to which our general partner would otherwise be held.

		In addition to the other more specific provisions limiting the obligations of our general partner, our partnership agreement further provides that our general partner, its general partner and its officers and directors will not be liable for monetary damages to us, our limited partners, or assignees for errors of judgment or for any acts or omissions unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that the general partner or its officers and directors acted in bad faith or engaged in fraud, willful misconduct or gross negligence.

In order to become one of our limited partners, a common unitholder is required to agree to be bound by the provisions in the partnership agreement, including the provisions discussed above. This is in accordance with the policy of the Delaware Act favoring the principle of freedom of contract and the enforceability of partnership agreements. The failure of a limited partner or assignee to sign a partnership agreement does not render the partnership agreement unenforceable against that person.

We must indemnify our general partner and Holly Logistic Services, L.L.C. and their officers, directors, and managers, to the fullest extent permitted by law, against liabilities, costs and expenses incurred by the general partner, Holly Logistic Services, L.L.C. or these other persons. We must provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud, willful misconduct or gross negligence. We also must provide this indemnification for criminal proceedings unless our general partner, Holly Logistic Services, L.L.C. or these other persons acted with knowledge that their conduct was unlawful. Thus, our general partner and Holly Logistic Services, L.L.C. could be indemnified for their negligent acts if they met requirements set forth above. To the extent that these provisions purport to include indemnification for liabilities arising under the Securities Act, in the opinion of the Securities and Exchange Commission, such indemnification is contrary to public policy and therefore unenforceable.

MATERIAL TAX CONSEQUENCES

This section is a summary of the material tax considerations that may be relevant to prospective unitholders who are individual citizens or residents of the United States and, unless otherwise noted in the following discussion, is the opinion of Vinson & Elkins L.L.P., counsel to our general partner and us, insofar as it relates to legal conclusions with respect to matters of U.S. federal income tax law. This section is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), existing and proposed Treasury regulations promulgated under the Internal Revenue Code (the “Treasury Regulations”) and current administrative rulings and court decisions, all of which are subject to change. Later changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “us” or “we” are references to Holly Energy Partners.

The following discussion does not comment on all federal income tax matters affecting us or our unitholders. Moreover, the discussion focuses on unitholders who are individual citizens or residents of the United States and has only limited application to corporations, estates, trusts, nonresident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, foreign persons, individual retirement accounts (IRAs), real estate investment trusts (REITs) or mutual funds. Accordingly, we encourage each prospective unitholder to consult, and depend on, his own tax advisor in analyzing the federal, state, local and foreign tax consequences particular to him of the ownership or disposition of common units.

No ruling has been or will be requested from the IRS regarding any matter affecting us or prospective unitholders. Instead, we will rely on opinions of Vinson & Elkins L.L.P. Unlike a ruling, an opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS. Any contest of this sort with the IRS may materially and adversely impact the market for the common units and the prices at which common units trade. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in cash available for distribution to our unitholders and our general partner and thus will be borne indirectly by our unitholders and our general partner. Furthermore, the tax treatment of us, or of an investment in us, may be significantly modified by future legislative or administrative changes or court decisions. Any modifications may or may not be retroactively applied.

All statements as to matters of law and legal conclusions, but not as to factual matters, contained in this section, unless otherwise noted, are the opinion of Vinson & Elkins L.L.P. and are based on the accuracy of the representations made by us.

For the reasons described below, Vinson & Elkins L.L.P. has not rendered an opinion with respect to the following specific federal income tax issues:

(1) the treatment of a unitholder whose common units are loaned to a short seller to cover a short sale of common units (please read “— Tax Consequences of Unit Ownership — Treatment of Short Sales”);

(2) whether our monthly convention for allocating taxable income and losses is permitted by existing Treasury Regulations (please read “— Disposition of Common Units — Allocations Between Transferors and Transferees”); and

(3) whether our method for depreciating Section 743 adjustments is sustainable in certain cases (please read “— Tax Consequences of Unit Ownership — Section 754 Election”).

Partnership Status

A partnership is not a taxable entity and incurs no federal income tax liability. Instead, each partner of a partnership is required to take into account his share of items of income, gain, loss and deduction of the partnership in computing his federal income tax liability, regardless of whether cash distributions are made to him by the partnership. Distributions by a partnership to a partner are generally not taxable to the partnership or the partner unless the amount of cash distributed to him is in excess of the partner’s adjusted basis in his partnership interest.

Section 7704 of the Internal Revenue Code provides that publicly traded partnerships will, as a general rule, be taxed as corporations. However, an exception, referred to as the “Qualifying Income Exception,” exists with respect to publicly traded partnerships of which 90% or more of the gross income for every taxable year consists of “qualifying income.” Qualifying income includes income and gains derived from the transportation, storage and processing of crude oil, natural gas and products thereof. Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of income that otherwise constitutes qualifying income. We estimate that less than 6% of our current gross income is not qualifying income; however, this estimate could change from time to time. Based upon and subject to this estimate, the factual representations made by us and our general partner and a review of the applicable legal authorities, Vinson &

Elkins L.L.P. is of the opinion that at least 90% of our current gross income constitutes qualifying income. The portion of our income that is qualifying income may change from time to time.

No ruling has been or will be sought from the IRS and the IRS has made no determination as to our status as a partnership for federal income tax purposes or whether our operations generate “qualifying income” under Section 7704 of the Internal Revenue Code. Instead, we will rely on the opinion of Vinson & Elkins L.L.P. on such matters. It is the opinion of Vinson & Elkins L.L.P. that, based upon the Internal Revenue Code, the Treasury Regulations, published revenue rulings and court decisions and the representations described below, we will be classified as a partnership and our operating partnership will be disregarded as an entity separate from us for federal income tax purposes.

In rendering its opinion, Vinson & Elkins L.L.P. has relied on factual representations made by us and our general partner. The representations made by us and our general partner upon which Vinson & Elkins L.L.P. has relied are:

(a) Neither we, the general partner of the operating partnership nor the operating partnership has elected or will elect to be treated as a corporation for federal income tax purposes; and

(b) For each taxable year, more than 90% of our gross income has been and will be income that Vinson & Elkins L.L.P. has opined or will opine is “qualifying income” within the meaning of Section 7704(d) of the Internal Revenue Code.

If we fail to meet the Qualifying Income Exception, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery (in which case the IRS may also require us to make adjustments with respect to our unitholders or pay other amounts), we will be treated as if we had transferred all of our assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which we fail to meet the Qualifying Income Exception, in return for stock in that corporation, and then distributed that stock to the unitholders in liquidation of their interests in us. This deemed contribution and liquidation should be tax-free to unitholders and us so long as we, at that time, do not have liabilities in excess of the tax basis of our assets. Thereafter, we would be treated as a corporation for federal income tax purposes.

If we were treated as an association taxable as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, our items of income, gain, loss and deduction would be reflected only on our tax return rather than being passed through to our unitholders, and our net income would be taxed to us at corporate rates. In addition, any distribution made to a unitholder would be treated as either taxable dividend income, to the extent of our current or accumulated earnings and profits, or, in the absence of earnings and profits, a nontaxable return of capital, to the extent of the unitholder’s tax basis in his common units, or taxable capital gain, after the unitholder’s tax basis in his common units is reduced to zero. Accordingly, taxation as a corporation would result in a material reduction in a unitholder’s cash flow and after-tax return and thus would likely result in a substantial reduction of the value of the units.

The discussion below is based on Vinson & Elkins L.L.P.’s opinion that we will be classified as a partnership for federal income tax purposes.

Limited Partner Status

Unitholders who have become limited partners of Holly Energy Partners will be treated as partners of Holly Energy Partners for federal income tax purposes. Also:

(a) assignees who have executed and delivered transfer applications, and are awaiting admission as limited partners, and

(b) unitholders whose common units are held in street name or by a nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of their common units,

will be treated as partners of Holly Energy Partners for federal income tax purposes. As there is no direct authority addressing assignees of common units who are entitled to execute and deliver transfer applications and thereby become entitled to direct the exercise of attendant rights, but who fail to execute and deliver transfer applications, Vinson & Elkins L.L.P.’s opinion does not extend to these persons. Furthermore, a purchaser or other transferee of common units who does not execute and deliver a transfer application may not receive some federal income tax information or reports furnished to record holders of common units unless the common units are held in a nominee or street name account and the nominee or broker has executed and delivered a transfer application for those common units.

A beneficial owner of common units whose units have been transferred to a short seller to complete a short sale would appear to lose his status as a partner with respect to those units for federal income tax purposes. Please read “— Tax Consequences of Unit Ownership — Treatment of Short Sales.”

Income, gains, deductions or losses would not appear to be reportable by a unitholder who is not a partner for federal income tax purposes, and any cash distributions received by a unitholder who is not a partner for federal income tax purposes would therefore appear to be fully taxable as ordinary income. These holders are urged to consult their own tax advisors with respect to their tax consequences of holding common units in Holly Energy Partners.

Tax Consequences of Unit Ownership

Flow-through of Taxable Income. We will not pay any federal income tax. Instead, each unitholder will be required to report on his income tax return his share of our income, gains, losses and deductions without regard to whether we make cash distributions to him. Consequently, we may allocate income to a unitholder even if he has not received a cash distribution. Each unitholder will be required to include in income his allocable share of our income, gains, losses and deductions for our taxable year ending with or within his taxable year.

Treatment of Distributions. Distributions by us to a unitholder generally will not be taxable to the unitholder for federal income tax purposes, except to the extent the amount of any such cash distribution exceeds his tax basis in his common units immediately before the distribution. Our cash distributions in excess of a unitholder’s tax basis generally will be considered to be gain from the sale or exchange of the common units, taxable in accordance with the rules described under “— Disposition of Common Units” below. Any reduction in a unitholder’s share of our liabilities for which no partner, including the general partner, bears the economic risk of loss, known as “nonrecourse liabilities,” will be treated as a distribution by us of cash to that unitholder. To the extent our distributions cause a unitholder’s “at-risk” amount to be less than zero at the end of any taxable year, he must recapture any losses deducted in previous years. Please read “— Limitations on Deductibility of Losses.”

A decrease in a unitholder’s percentage interest in us because of our issuance of additional common units will decrease his share of our nonrecourse liabilities, and thus will result in a corresponding deemed distribution of cash. This deemed distribution may constitute a non-pro rata distribution. A non-pro rata distribution of money or property may result in ordinary income to a unitholder, regardless of his tax basis in his common units, if the distribution reduces the unitholder’s share of our “unrealized receivables,” including depreciation recapture, and/or substantially appreciated “inventory items,” both as defined in the Internal Revenue Code, and collectively, “Section 751 Assets.” To that extent, he will be treated as having been distributed his proportionate share of the Section 751 Assets and then having exchanged those assets with us in return for the non-pro rata portion of the actual distribution made to him. This latter deemed exchange will generally result in the unitholder’s realization of ordinary income, which will equal the excess of (1) the non-pro rata portion of that distribution over (2) the unitholder’s tax basis (generally zero) for the share of Section 751 Assets deemed relinquished in the exchange.

Basis of Common Units. A unitholder’s initial tax basis for his common units will be the amount he paid for the common units plus his share of our nonrecourse liabilities. That basis will be increased by his share of our income and by any increases in his share of our nonrecourse liabilities. That basis will be decreased, but not below zero, by distributions from us, by the unitholder’s share of our losses, by any

decreases in his share of our nonrecourse liabilities and by his share of our expenditures that are not deductible in computing taxable income and are not required to be capitalized. A unitholder will have no share of our debt that is recourse to our general partner, but will have a share, generally based on his share of profits, of our nonrecourse liabilities. Please read “— Disposition of Common Units — Recognition of Gain or Loss.”

Limitations on Deductibility of Losses. The deduction by a unitholder of his share of our losses will be limited to the tax basis in his units and, in the case of an individual unitholder, estate, trust, or corporate unitholder (if more than 50% of the value of the corporate unitholder’s stock is owned directly or indirectly by or for five or fewer individuals or some tax-exempt organizations) to the amount for which the unitholder is considered to be “at risk” with respect to our activities, if that is less than his tax basis. A common unitholder subject to these limitations must recapture losses deducted in previous years to the extent that distributions cause his at-risk amount to be less than zero at the end of any taxable year. Losses disallowed to a unitholder or recaptured as a result of these limitations will carry forward and will be allowable as a deduction to the extent that his at-risk amount is subsequently increased, provided such losses do not exceed such common unitholder’s tax basis in his common units. Upon the taxable disposition of a unit, any gain recognized by a unitholder can be offset by losses that were previously suspended by the at-risk limitation but may not be offset by losses suspended by the basis limitation. Any loss previously suspended by the at-risk limitation in excess of that gain would no longer be utilizable.

In general, a unitholder will be at risk to the extent of the tax basis of his units, excluding any portion of that basis attributable to his share of our nonrecourse liabilities, reduced by (i) any portion of that basis representing amounts otherwise protected against loss because of a guarantee, stop loss agreement or other similar arrangement and (ii) any amount of money he borrows to acquire or hold his units, if the lender of those borrowed funds owns an interest in us, is related to the unitholder or can look only to the units for repayment. A unitholder’s at-risk amount will increase or decrease as the tax basis of the unitholder’s units increases or decreases, other than tax basis increases or decreases attributable to increases or decreases in his share of our nonrecourse liabilities.

In addition to the basis and at-risk limitations on the deductibility of losses, the passive loss limitations generally provide that individuals, estates, trusts and some closely-held corporations and personal service corporations can deduct losses from passive activities, which are generally trade or business activities in which the taxpayer does not materially participate, only to the extent of the taxpayer’s income from those passive activities. The passive loss limitations are applied separately with respect to each publicly traded partnership. Consequently, any passive losses we generate will only be available to offset our passive income generated in the future and will not be available to offset income from other passive activities or investments, including our investments or investments in other publicly traded partnerships, or salary or active business income. Passive losses that are not deductible because they exceed a unitholder’s share of income we generate may be deducted in full when he disposes of his entire investment in us in a fully taxable transaction with an unrelated party. The passive loss limitations are applied after other applicable limitations on deductions, including the at-risk rules and the basis limitation.

A unitholder’s share of our net income may be offset by any of our suspended passive losses, but it may not be offset by any other current or carryover losses from other passive activities, including those attributable to other publicly traded partnerships.

Limitations on Interest Deductions. The deductibility of a non-corporate taxpayer’s “investment interest expense” is generally limited to the amount of that taxpayer’s “net investment income.” Investment interest expense includes:


	•	interest on indebtedness properly allocable to property held for investment;

	•	our interest expense attributed to portfolio income; and

	•	the portion of interest expense incurred to purchase or carry an interest in a passive activity to the extent attributable to portfolio income.

The computation of a unitholder’s investment interest expense will take into account interest on any margin account borrowing or other loan incurred to purchase or carry a unit. Net investment income includes gross income from property held for investment and amounts treated as portfolio income under the passive loss rules, less deductible expenses, other than interest, directly connected with the production of investment income, but generally does not include gains attributable to the disposition of property held for investment or qualified dividend income. The IRS has indicated that the net passive income earned by a publicly traded partnership will be treated as investment income to its unitholders. In addition, the unitholder’s share of our portfolio income will be treated as investment income.

Entity-Level Collections. If we are required or elect under applicable law to pay any federal, state, local or foreign income tax on behalf of any unitholder or our general partner or any former unitholder, we are authorized to pay those taxes from our funds. That payment, if made, will be treated as a distribution of cash to the unitholder on whose behalf the payment was made. If the payment is made on behalf of a person whose identity cannot be determined, we are authorized to treat the payment as a distribution to all current unitholders. We are authorized to amend our partnership agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of units and to adjust later distributions, so that after giving effect to these distributions, the priority and characterization of distributions otherwise applicable under our partnership agreement is maintained as nearly as is practicable. Payments by us as described above could give rise to an overpayment of tax on behalf of an individual unitholder in which event the unitholder would be required to file a claim in order to obtain a credit or refund.

Allocation of Income, Gain, Loss and Deduction. In general, if we have a net profit, our items of income, gain, loss and deduction will be allocated among our general partner and the unitholders in accordance with their percentage interests in us. At any time that distributions are made to the common units in excess of distributions to the subordinated units, or incentive distributions are made to our general partner, gross income will be allocated to the recipients to the extent of these distributions. If we have a net loss, that loss will be allocated first to our general partner and the unitholders in accordance with their percentage interests in us to the extent of their positive capital accounts and, second, to our general partner.

Specified items of our income, gain, loss and deduction will be allocated to account for (i) any difference between the tax basis and fair market value of our assets that exists at the time of an offering and (ii) any difference between the tax basis and fair market value of any property contributed to us by our general partner and its affiliates that exists at the time of contribution, referred to in this discussion as the “Adjusted Property.” The effect of these allocations, referred to as Section 704(c) Allocations, to a unitholder purchasing common units from us in an offering will be essentially the same as if the tax bases of our assets were equal to their fair market value at the time of such offering. In the event we issue additional common units or engage in certain other transactions in the future, “reverse Section 704(c) Allocations,” similar to the Section 704(c) Allocations described above, will be made to our general partner and persons that hold our units immediately prior to such issuance or other transactions to account for the difference between the “book” basis for purposes of maintaining capital accounts and the fair market value of all property held by us at the time of such future issuance or other transaction. In addition, items of recapture income will be allocated to the extent possible to the unitholder who was allocated the deduction giving rise to the treatment of that gain as recapture income in order to minimize the recognition of ordinary income by some unitholders. Finally, although we do not expect that our operations will result in the creation of negative capital accounts, if negative capital accounts nevertheless result, items of our income and gain will be allocated in an amount and manner sufficient to eliminate the negative balance as quickly as possible.

An allocation of items of our income, gain, loss or deduction, other than an allocation required by the Internal Revenue Code to eliminate the difference between a partner’s “book” capital account, credited with the fair market value of Adjusted Property, and “tax” capital account, credited with the tax basis of Adjusted Property, referred to in this discussion as the “Book-Tax Disparity,” will generally be given effect for federal income tax purposes in determining a partner’s share of an item of income, gain, loss or deduction only if the allocation has substantial economic effect. In any other case, a partner’s share of an item will be determined

on the basis of his interest in us, which will be determined by taking into account all the facts and circumstances, including:


	•	his relative contributions to us;

	•	the interests of all the partners in profits and losses;

	•	the interest of all the partners in cash flow; and

	•	the rights of all the partners to distributions of capital upon liquidation.

Vinson & Elkins L.L.P. is of the opinion that, with the exception of the issues described in “— Section 754 Election” and “— Disposition of Common Units — Allocations Between Transferors and Transferees,” allocations under our partnership agreement will be given effect for federal income tax purposes in determining a partner’s share of an item of income, gain, loss or deduction.

Treatment of Short Sales. A unitholder whose units are loaned to a “short seller” to cover a short sale of units may be considered as having disposed of those units. If so, he would no longer be a partner for those units during the period of the loan and may recognize gain or loss from the disposition. As a result, during this period:


	•	any of our income, gain, loss or deduction with respect to those units would not be reportable by the unitholder;

	•	any cash distributions received by the unitholder as to those units would be fully taxable; and

	•	all of these distributions would appear to be ordinary income.

Vinson & Elkins L.L.P. has not rendered an opinion regarding the tax treatment of a unitholder whose common units are loaned to a short seller to cover a short sale of common units; therefore, unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing and loaning their units. The IRS has announced that it is actively studying issues relating to the tax treatment of short sales of partnership interests. Please also read “— Disposition of Common Units — Recognition of Gain or Loss.”

Alternative Minimum Tax. Each unitholder will be required to take into account his distributive share of any items of our income, gain, loss or deduction for purposes of the alternative minimum tax. The current minimum tax rate for noncorporate taxpayers is 26% on the first $175,000 of alternative minimum taxable income in excess of the exemption amount and 28% on any additional alternative minimum taxable income. Prospective unitholders are urged to consult with their tax advisors as to the impact of an investment in units on their liability for the alternative minimum tax.

Tax Rates. Under current law, the highest marginal U.S. federal income tax rate applicable to ordinary income of individuals is 35% and the highest marginal U.S. federal income tax rate applicable to long-term capital gains (generally, capital gains on certain assets held for more than 12 months) of individuals is 15%. However, absent new legislation extending the current rates, beginning January 1, 2011, the highest marginal U.S. federal income tax rate applicable to ordinary income and long-term capital gains of individuals will increase to 39.6% and 20%, respectively.

Section 754 Election. We have made the election permitted by Section 754 of the Internal Revenue Code. That election is irrevocable without the consent of the IRS. The election will generally permit us to adjust a common unit purchaser’s tax basis in our assets (“inside basis”) under Section 743(b) of the Internal Revenue Code to reflect his purchase price. This election does not apply to a person who purchases common units directly from us. The Section 743(b) adjustment belongs to the purchaser and not to other unitholders. For purposes of this discussion, a unitholder’s inside basis in our assets will be considered to have two components: (1) his share of our tax basis in our assets (“common basis”) and (2) his Section 743(b) adjustment to that basis.

Where the remedial allocation method is adopted (which we have adopted as to our properties), the Treasury Regulations under Section 743 of the Internal Revenue Code require a portion of the Section 743(b) adjustment that is attributable to recovery property subject to depreciation under Section 168 of the Internal Revenue Code whose book basis is in excess of its tax basis to be depreciated over the remaining cost recovery period for the property’s unamortized book-tax disparity. Under Treasury Regulation Section 1.167(c)-1(a)(6), a Section 743(b) adjustment attributable to property subject to depreciation under Section 167 of the Internal Revenue Code, rather than cost recovery deductions under Section 168, is generally required to be depreciated using either the straight-line method or the 150% declining balance method. Under our partnership agreement, our general partner is authorized to take a position to preserve the uniformity of units even if that position is not consistent with these and any other Treasury Regulations. Please read “— Uniformity of Units.”

Although Vinson & Elkins L.L.P. is unable to opine as to the validity of this approach because there is no direct or indirect controlling authority on this issue, we intend to depreciate the portion of a Section 743(b) adjustment attributable to unrealized appreciation in the value of Adjusted Property, to the extent of any unamortized Book-Tax Disparity, using a rate of depreciation or amortization derived from the depreciation or amortization method and useful life applied to the property’s unamortized book-tax disparity, or treat that portion as non-amortizable to the extent attributable to property which is not amortizable. This method is consistent with the methods employed by other publicly traded partnerships but is arguably inconsistent with Treasury Regulation Section 1.167(c)-1(a)(6), which is not expected to directly apply to a material portion of our assets, and Treasury Regulation Section 1.197-2(g)(3). To the extent this Section 743(b) adjustment is attributable to appreciation in value in excess of the unamortized Book-Tax Disparity, we will apply the rules described in the Treasury Regulations and legislative history. If we determine that this position cannot reasonably be taken, we may take a depreciation or amortization position under which all purchasers acquiring units in the same month would receive depreciation or amortization, whether attributable to common basis or a Section 743(b) adjustment, based upon the same applicable rate as if they had purchased a direct interest in our assets. This kind of aggregate approach may result in lower annual depreciation or amortization deductions than would otherwise be allowable to some unitholders. Please read “— Uniformity of Units.” A unitholder’s tax basis for his common units is reduced by his share of our deductions (whether or not such deductions were claimed on an individual’s income tax return) so that any position we take that understates deductions will overstate the common unitholder’s basis in his common units, which may cause the unitholder to understate gain or overstate loss on any sale of such units. Please read “— Disposition of Common Units — Recognition of Gain or Loss.” The IRS may challenge our position with respect to depreciating or amortizing the Section 743(b) adjustment we take to preserve the uniformity of the units. If such a challenge were sustained, the gain from the sale of units might be increased without the benefit of additional deductions.

A Section 754 election is advantageous if the transferee’s tax basis in his units is higher than the units’ share of the aggregate tax basis of our assets immediately prior to the transfer. In that case, as a result of the election, the transferee would have, among other items, a greater amount of depreciation deductions and his share of any gain or loss on a sale of our assets would be less. Conversely, a Section 754 election is disadvantageous if the transferee’s tax basis in his units is lower than those units’ share of the aggregate tax basis of our assets immediately prior to the transfer. Thus, the fair market value of the units may be affected either favorably or unfavorably by the election. A basis adjustment is required regardless of whether a Section 754 election is made in the case of a transfer of an interest in us if we have a substantial built — in loss immediately after the transfer, or if we distribute property and have a substantial basis reduction. Generally a built — in loss or a basis reduction is substantial if it exceeds $250,000.

The calculations involved in the Section 754 election are complex and will be made on the basis of assumptions as to the value of our assets and other matters. For example, the allocation of the Section 743(b) adjustment among our assets must be made in accordance with the Internal Revenue Code. The IRS could seek to reallocate some or all of any Section 743(b) adjustment allocated by us to our tangible assets to goodwill instead. Goodwill, as an intangible asset, is generally nonamortizable or amortizable over a longer period of time or under a less accelerated method than our tangible assets. We cannot assure you that the determinations we make will not be successfully challenged by the IRS and that the deductions resulting from

them will not be reduced or disallowed altogether. Should the IRS require a different basis adjustment to be made, and should, in our opinion, the expense of compliance exceed the benefit of the election, we may seek permission from the IRS to revoke our Section 754 election. If permission is granted, a subsequent purchaser of units may be allocated more income than he would have been allocated had the election not been revoked.

Tax Treatment of Operations

Accounting Method and Taxable Year. We use the year ending December 31 as our taxable year and the accrual method of accounting for federal income tax purposes. Each unitholder will be required to include in income his share of our income, gain, loss and deduction for our taxable year ending within or with his taxable year. In addition, a unitholder who has a taxable year ending on a date other than December 31 and who disposes of all of his units following the close of our taxable year but before the close of his taxable year must include his share of our income, gain, loss and deduction in income for his taxable year, with the result that he will be required to include in income for his taxable year his share of more than twelve months of our income, gain, loss and deduction. Please read “— Disposition of Common Units — Allocations Between Transferors and Transferees.”

Tax Basis, Depreciation and Amortization. The tax basis of our assets will be used for purposes of computing depreciation and cost recovery deductions and, ultimately, gain or loss on the disposition of these assets. The federal income tax burden associated with the difference between the fair market value of our assets and their tax basis immediately prior to an offering will be borne by partners holding interests in us immediately prior to that offering. Please read “— Tax Consequences of Unit Ownership — Allocation of Income, Gain, Loss and Deduction.”

To the extent allowable, we may elect to use the depreciation and cost recovery methods that will result in the largest deductions being taken in the early years after assets are placed in service. We are not entitled to any amortization deductions with respect to any goodwill conveyed to us on formation. Property we subsequently acquire or construct may be depreciated using accelerated methods permitted by the Internal Revenue Code.

If we dispose of depreciable property by sale, foreclosure or otherwise, all or a portion of any gain, determined by reference to the amount of depreciation previously deducted and the nature of the property, may be subject to the recapture rules and taxed as ordinary income rather than capital gain. Similarly, a unitholder who has taken cost recovery or depreciation deductions with respect to property we own will likely be required to recapture some or all of those deductions as ordinary income upon a sale of his interest in us. Please read “— Tax Consequences of Unit Ownership — Allocation of Income, Gain, Loss and Deduction” and “— Disposition of Common Units — Recognition of Gain or Loss.”

The costs incurred in selling our units (called “syndication expenses”) must be capitalized and cannot be deducted currently, ratably or upon our termination. There are uncertainties regarding the classification of costs as organization expenses, which may be amortized by us, and as syndication expenses, which may not be amortized by us. The underwriting discounts and commissions we incur will be treated as syndication expenses.

Valuation and Tax Basis of Our Properties. The federal income tax consequences of the ownership and disposition of units will depend in part on our estimates of the relative fair market values, and the initial tax bases, of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we will make many of the relative fair market value estimates ourselves. These estimates and determinations of basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deductions previously reported by unitholders might change, and unitholders might be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

Disposition of Common Units

Recognition of Gain or Loss. Gain or loss will be recognized on a sale of units equal to the difference between the amount realized and the unitholder’s tax basis for the units sold. A unitholder’s amount realized will be measured by the sum of the cash or the fair market value of other property received by him plus his share of our nonrecourse liabilities. Because the amount realized includes a unitholder’s share of our nonrecourse liabilities, the gain recognized on the sale of units could result in a tax liability in excess of any cash received from the sale.

Prior distributions from us in excess of cumulative net taxable income for a common unit that decreased a unitholder’s tax basis in that common unit will, in effect, become taxable income if the common unit is sold at a price greater than the unitholder’s tax basis in that common unit, even if the price received is less than his original cost.

Except as noted below, gain or loss recognized by a unitholder, other than a “dealer” in units, on the sale or exchange of a unit will generally be taxable as capital gain or loss. Capital gain recognized by an individual on the sale of units held for more than 12 months will generally be taxed at a maximum U.S. federal income tax rate of 15% through December 31, 2010 and 20% thereafter (absent new legislation extending the current rate). However, a portion of this gain or loss, which will likely be substantial, will be separately computed and taxed as ordinary income or loss under Section 751 of the Internal Revenue Code to the extent attributable to assets giving rise to depreciation recapture or other “unrealized receivables” or to “inventory items” we own. The term “unrealized receivables” includes potential recapture items, including depreciation recapture. Ordinary income attributable to unrealized receivables, inventory items and depreciation recapture may exceed net taxable gain realized upon the sale of a unit and may be recognized even if there is a net taxable loss realized on the sale of a unit. Thus, a unitholder may recognize both ordinary income and a capital loss upon a sale of units. Net capital losses may offset capital gains and no more than $3,000 of ordinary income, in the case of individuals, and may only be used to offset capital gains in the case of corporations.

The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests sold using an “equitable apportionment” method, which generally means that the tax basis allocated to the interest sold equals an amount that bears the same relation to the partner’s tax basis in his entire interest in the partnership as the value of the interest sold bears to the value of the partner’s entire interest in the partnership. Treasury Regulations under Section 1223 of the Internal Revenue Code allow a selling unitholder who can identify common units transferred with an ascertainable holding period to elect to use the actual holding period of the common units transferred. Thus, according to the ruling described above, a common unitholder will be unable to select high or low basis common units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, he may designate specific common units sold for purposes of determining the holding period of units transferred. A unitholder electing to use the actual holding period of common units transferred must consistently use that identification method for all subsequent sales or exchanges of common units. A unitholder considering the purchase of additional units or a sale of common units purchased in separate transactions is urged to consult his tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

Specific provisions of the Internal Revenue Code affect the taxation of some financial products and securities, including partnership interests, by treating a taxpayer as having sold an “appreciated” partnership interest, one in which gain would be recognized if it were sold, assigned or terminated at its fair market value, if the taxpayer or related persons enter(s) into:


	•	a short sale;

	•	an offsetting notional principal contract; or

	•	a futures or forward contract with respect to the partnership interest or substantially identical property.

Moreover, if a taxpayer has previously entered into a short sale, an offsetting notional principal contract or a futures or forward contract with respect to the partnership interest, the taxpayer will be treated as having sold that position if the taxpayer or a related person then acquires the partnership interest or substantially identical property. The Secretary of the Treasury is also authorized to issue regulations that treat a taxpayer that enters into transactions or positions that have substantially the same effect as the preceding transactions as having constructively sold the financial position.

Allocations Between Transferors and Transferees. In general, our taxable income and losses will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the unitholders in proportion to the number of units owned by each of them as of the opening of the applicable exchange on the first business day of the month, which we refer to in this prospectus as the “Allocation Date.” However, gain or loss realized on a sale or other disposition of our assets other than in the ordinary course of business will be allocated among the unitholders on the Allocation Date in the month in which that gain or loss is recognized. As a result, a unitholder transferring units may be allocated income, gain, loss and deduction realized after the date of transfer.

Although simplifying conventions are contemplated by the Internal Revenue Code and most publicly traded partnerships use similar simplifying conventions, the use of this method may not be permitted under existing Treasury Regulations. Accordingly, Vinson & Elkins L.L.P. is unable to opine on the validity of this method of allocating income and deductions between transferor and transferee unitholders. If this method is not allowed under the Treasury Regulations, or only applies to transfers of less than all of the unitholder’s interest, our taxable income or losses might be reallocated among the unitholders. We are authorized to revise our method of allocation between transferor and transferee unitholders, as well as unitholders whose interests vary during a taxable year, to conform to a method permitted under future Treasury Regulations.

A unitholder who owns units at any time during a quarter and who disposes of them prior to the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deductions attributable to that quarter but will not be entitled to receive that cash distribution.

Notification Requirements. A unitholder who sells any of his units is generally required to notify us in writing of that sale within 30 days after the sale (or, if earlier, January 15 of the year following the sale). A purchaser of units who purchases units from another unitholder is also generally required to notify us in writing of that purchase within 30 days after the purchase. Upon receiving such notifications, we are required to notify the IRS of that transaction and to furnish specified information to the transferor and transferee. Failure to notify us of a purchase may, in some cases, lead to the imposition of penalties. However, these reporting requirements do not apply to a sale by an individual who is a citizen of the United States and who effects the sale or exchange through a broker who will satisfy such requirements.

Constructive Termination. We will be considered to have been terminated for tax purposes if there are sales or exchanges which, in the aggregate, constitute 50% or more of the total interests in our capital and profits within a twelve-month period. For purposes of measuring whether the 50% threshold is reached, multiple sales of the same interest are counted only once. A constructive termination results in the closing of our taxable year for all unitholders. In the case of a unitholder reporting on a taxable year other than a fiscal year ending December 31, the closing of our taxable year may result in more than twelve months of our taxable income or loss being includable in his taxable income for the year of termination. A constructive termination occurring on a date other than December 31 will result in us filing two tax returns (and unitholders receiving two Schedules K-1) for one fiscal year and the cost of the preparation of these returns will be borne by all common unitholders. We would be required to make new tax elections after a termination, including a new election under Section 754 of the Internal Revenue Code, and a termination would result in a deferral of our deductions for depreciation. A termination could also result in penalties if we were unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject us to, any tax legislation enacted before the termination.

Uniformity of Units

Because we cannot match transferors and transferees of units, we must maintain uniformity of the economic and tax characteristics of the units to a purchaser of these units. In the absence of uniformity, we may be unable to completely comply with a number of federal income tax requirements, both statutory and regulatory. A lack of uniformity can result from a literal application of Treasury Regulation Section 1.167(c)-1(a)(6). Any non-uniformity could have a negative impact on the value of the units. Please read “— Tax Consequences of Unit Ownership — Section 754 Election.”

We intend to depreciate the portion of a Section 743(b) adjustment attributable to unrealized appreciation in the value of Adjusted Property, to the extent of any unamortized Book-Tax Disparity, using a rate of depreciation or amortization derived from the depreciation or amortization method and useful life applied to the property’s unamortized book-tax disparity, or treat that portion as nonamortizable, to the extent attributable to property the common basis of which is not amortizable, consistent with the regulations under Section 743 of the Internal Revenue Code, even though that position may be inconsistent with Treasury Regulation Section 1.167(c)-1(a)(6), which is not expected to directly apply to a material portion of our assets, and Treasury Regulation Section 1.197-2(g)(3). Please read “— Tax Consequences of Unit Ownership — Section 754 Election.” To the extent that the Section 743(b) adjustment is attributable to appreciation in value in excess of the unamortized Book-Tax Disparity, we will apply the rules described in the Treasury Regulations and legislative history. If we determine that this position cannot reasonably be taken, we may adopt a depreciation and amortization position under which all purchasers acquiring units in the same month would receive depreciation and amortization deductions, whether attributable to a common basis or Section 743(b) adjustment, based upon the same applicable methods and lives as if they had purchased a direct interest in our property. If this position is adopted, it may result in lower annual depreciation and amortization deductions than would otherwise be allowable to some unitholders and risk the loss of depreciation and amortization deductions not taken in the year that these deductions are otherwise allowable. This position will not be adopted if we determine that the loss of depreciation and amortization deductions will have a material adverse effect on the unitholders. If we choose not to utilize this aggregate method, we may use any other reasonable depreciation and amortization method to preserve the uniformity of the intrinsic tax characteristics of any units that would not have a material adverse effect on the unitholders. The IRS may challenge any method of depreciating the Section 743(b) adjustment described in this paragraph. If this challenge were sustained, the uniformity of units might be affected, and the gain from the sale of units might be increased without the benefit of additional deductions. Please read “— Disposition of Common Units — Recognition of Gain or Loss.”

Tax-Exempt Organizations and Other Investors

Ownership of units by employee benefit plans, other tax-exempt organizations, non-resident aliens, foreign corporations and other foreign persons raises issues unique to those investors and, as described below, may have substantially adverse tax consequences to them. If you are a tax-exempt entity or a non-U.S. person, you should consult you tax advisor before investing in our common units.

Employee benefit plans and most other organizations exempt from federal income tax, including individual retirement accounts and other retirement plans, are subject to federal income tax on unrelated business taxable income. Virtually all of our income allocated to a unitholder that is a tax-exempt organization will be unrelated business taxable income and will be taxable to them.

Non-resident aliens and foreign corporations, trusts or estates that own units will be considered to be engaged in business in the United States because of the ownership of units. As a consequence, they will be required to file federal tax returns to report their share of our income, gain, loss or deduction and pay federal income tax at regular rates on their share of our net income or gain. Moreover, under rules applicable to publicly traded partnerships, we will withhold at the highest applicable effective tax rate from cash distributions made quarterly to foreign unitholders. Each foreign unitholder must obtain a taxpayer identification number from the IRS and submit that number to our transfer agent on a Form W-8BEN or applicable

substitute form in order to obtain credit for these withholding taxes. A change in applicable law may require us to change these procedures.

In addition, because a foreign corporation that owns units will be treated as engaged in a United States trade or business, that corporation may be subject to the United States branch profits tax at a rate of 30%, in addition to regular federal income tax, on its share of our income and gain, as adjusted for changes in the foreign corporation’s “U.S. net equity,” which is effectively connected with the conduct of a United States trade or business. That tax may be reduced or eliminated by an income tax treaty between the United States and the country in which the foreign corporate unitholder is a “qualified resident.” In addition, this type of unitholder is subject to special information reporting requirements under Section 6038C of the Internal Revenue Code.

A foreign unitholder who sells or otherwise disposes of a common unit will be subject to U.S. federal income tax on gain realized from the sale or disposition of that unit to the extent the gain is effectively connected with a U.S. trade or business of the foreign unitholder. Under a ruling published by the IRS, interpreting the scope of “effectively connected income,” a foreign unitholder would be considered to be engaged in a trade or business in the U.S. by virtue of the U.S. activities of the partnership, and part or all of that unitholder’s gain would be effectively connected with that unitholder’s indirect U.S. trade or business. Moreover, under the Foreign Investment in Real Property Tax Act, a foreign common unitholder generally will be subject to U.S. federal income tax upon the sale or disposition of a common unit if (i) he owned (directly or constructively applying certain attribution rules) more than 5% of our common units at any time during the five-year period ending on the date of such disposition and (ii) 50% or more of the fair market value of all of our assets consisted of U.S. real property interests at any time during the shorter of the period during which such unitholder held the common units or the 5-year period ending on the date of disposition. Currently, more than 50% of our assets consist of U.S. real property interests and we do not expect that to change in the foreseeable future. Therefore, foreign unitholders may be subject to federal income tax on gain from the sale or disposition of their units.

Administrative Matters

Information Returns and Audit Procedures. We intend to furnish to each unitholder, within 90 days after the close of each calendar year, specific tax information, including a Schedule K-1, which describes his share of our income, gain, loss and deduction for our preceding taxable year. In preparing this information, which will not be reviewed by counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each unitholder’s share of income, gain, loss and deduction. We cannot assure you that those positions will yield a result that conforms to the requirements of the Internal Revenue Code, Treasury Regulations or administrative interpretations of the IRS. Neither we nor Vinson & Elkins L.L.P. can assure prospective unitholders that the IRS will not successfully contend in court that those positions are impermissible. Any challenge by the IRS could negatively affect the value of the units.

The IRS may audit our federal income tax information returns. Adjustments resulting from an IRS audit may require each unitholder to adjust a prior year’s tax liability, and possibly may result in an audit of his return. Any audit of a unitholder’s return could result in adjustments not related to our returns as well as those related to our returns.

Partnerships generally are treated as separate entities for purposes of federal tax audits, judicial review of administrative adjustments by the IRS and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings with the partners. The Internal Revenue Code requires that one partner be designated as the “Tax Matters Partner” for these purposes. Our partnership agreement names our general partner as our Tax Matters Partner.

The Tax Matters Partner has made and will make some elections on our behalf and on behalf of unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items in our returns. The Tax Matters Partner may bind a unitholder with less than a 1% profits interest in us to a settlement with the IRS unless that unitholder elects, by filing a

statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any unitholder having at least a 1% interest in profits or by any group of unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review will go forward, and each unitholder with an interest in the outcome may participate.

A unitholder must file a statement with the IRS identifying the treatment of any item on his federal income tax return that is not consistent with the treatment of the item on our return. Intentional or negligent disregard of this consistency requirement may subject a unitholder to substantial penalties.

Nominee Reporting. Persons who hold an interest in us as a nominee for another person are required to furnish to us:

(a) the name, address and taxpayer identification number of the beneficial owner and the nominee;

(b) whether the beneficial owner is

(1) a person that is not a United States person,

(2) a foreign government, an international organization or any wholly owned agency or instrumentality of either of the foregoing, or

(3) a tax-exempt entity;

(d) specific information including the dates of acquisitions and transfers, means of acquisitions and transfers, and acquisition cost for purchases, as well as the amount of net proceeds from sales.

Brokers and financial institutions are required to furnish additional information, including whether they are United States persons and specific information on units they acquire, hold or transfer for their own account. A penalty of $50 per failure, up to a maximum of $100,000 per calendar year, is imposed by the Internal Revenue Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the units with the information furnished to us.

Accuracy-related Penalties. An additional tax equal to 20% of the amount of any portion of an underpayment of tax that is attributable to one or more specified causes, including negligence or disregard of rules or regulations, substantial understatements of income tax and substantial valuation misstatements, is imposed by the Internal Revenue Code. No penalty will be imposed, however, for any portion of an underpayment if it is shown that there was a reasonable cause for that portion and that the taxpayer acted in good faith regarding that portion.

For individuals, a substantial understatement of income tax in any taxable year exists if the amount of the understatement exceeds the greater of 10% of the tax required to be shown on the return for the taxable year or $5,000. The amount of any understatement subject to penalty generally is reduced if any portion is attributable to a position adopted on the return:

(1) for which there is, or was, “substantial authority,” or

(2) as to which there is a reasonable basis and the pertinent facts of that position are disclosed on the return.

If any item of income, gain, loss or deduction included in the distributive shares of unitholders might result in that kind of an “understatement” of income for which no “substantial authority” exists, we must disclose the pertinent facts on our return. In addition, we will make a reasonable effort to furnish sufficient information for unitholders to make adequate disclosure on their returns and to take other actions as may be appropriate to permit unitholders to avoid liability for this penalty. More stringent rules apply to “tax shelters,” which we do not believe includes us, or any of our investments, plans or arrangements.

A substantial valuation misstatement exists if the value of any property, or the adjusted basis of any property, claimed on a tax return is 150% or more of the amount determined to be the correct amount of the valuation or adjusted basis. No penalty is imposed unless the portion of the underpayment attributable to a substantial valuation misstatement exceeds $5,000 ($10,000 for most corporations). If the valuation claimed on a return is 200% or more than the correct valuation, the penalty imposed increases to 40%. We do not anticipate making any valuation misstatements.

Reportable Transactions. If we were to engage in a “reportable transaction,” we (and possibly you and others) would be required to make a detailed disclosure of the transaction to the IRS. A transaction may be a reportable transaction based upon any of several factors, including the fact that it is a type of tax avoidance transaction publicly identified by the IRS as a “listed transaction” or that it produces certain kinds of losses for partnerships, individuals, S corporations, and trusts in excess of $2 million in any single year, or $4 million in any combination of 6 successive tax years. Our participation in a reportable transaction could increase the likelihood that our federal income tax information return (and possibly your tax return) would be audited by the IRS. Please read “— Information Returns and Audit Procedures.”

Moreover, if we were to participate in a reportable transaction with a significant purpose to avoid or evade tax, or in any listed transaction, you may be subject to the following provisions of the American Jobs Creation Act of 2004:


	•	accuracy-related penalties with a broader scope, significantly narrower exceptions, and potentially greater amounts than described above at “— Accuracy-related Penalties,”

	•	for those persons otherwise entitled to deduct interest on federal tax deficiencies, nondeductibility of interest on any resulting tax liability, and

	•	in the case of a listed transaction, an extended statute of limitations.

We do not expect to engage in any “reportable transactions.”

State, Local, Foreign and Other Tax Considerations

In addition to federal income taxes, a unitholder will likely be subject to other taxes, including state, local and foreign income taxes, unincorporated business taxes, and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which we do business or own property or in which a unitholder is a resident. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on his investment in us. We currently own property or do business in New Mexico, Arizona, Washington, Texas, Utah and Idaho. We may also own property or do business in other jurisdictions in the future. Although a unitholder may not be required to file a return and pay taxes in some jurisdictions because its income from that jurisdiction falls below the filing and payment requirement, unitholders will be required to file state income tax returns and to pay state income taxes in some or all of the states in which we do business or own property and may be subject to penalties for failure to comply with those requirements. In some states, tax losses may not produce a tax benefit in the year incurred and also may not be available to offset income in subsequent taxable years. Some of the states may require us, or we may elect, to withhold a percentage of income from amounts to be distributed to a unitholder who is not a resident of the state. Withholding, the amount of which may be greater or less than a particular unitholder’s income tax liability to the state, generally does not relieve a nonresident unitholder from the obligation to file an income tax return. Amounts withheld may be treated as if distributed to unitholders for purposes of determining the amounts distributed by us. Please read “— Tax Consequences of Unit Ownership — Entity-Level Collections.” Based on current law and our estimate of our future operations, our general partner anticipates that any amounts required to be withheld will not be material. We may also own property or do business in other states in the future.

It is the responsibility of each unitholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, of his investment in us. Accordingly, each prospective unitholder is urged to consult, and depend upon, his own tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local, and foreign as well as United States federal tax returns,

that may be required of him. Vinson & Elkins L.L.P. has not rendered an opinion on the state, local or foreign tax consequences of an investment in us.

Tax Consequences of Ownership of Preferred Units or Debt Securities

A description of the material federal income tax consequences of the acquisition, ownership and disposition of preferred units or debt securities will be set forth in the prospectus supplement relating to the offering of any preferred units or debt securities, as applicable.

PLAN OF DISTRIBUTION

We may sell the common units, preferred units and debt securities being offered hereby directly, through agents or to or through underwriters or dealers. We may distribute the common units, preferred units or debt securities from time to time in one or more transactions at: a fixed price; market prices prevailing at the time of sale; prices related to prevailing market prices; or negotiated prices.

We, or agents designated by us, may directly solicit, from time to time, offers to purchase the securities. Any such agent may be deemed to be an underwriter as that term is defined in the Securities Act. We will name the agents involved in the offer or sale of the securities and describe any commissions payable by us to these agents in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, these agents will be acting on a best efforts basis for the period of their appointment. The agents may be entitled under agreements which may be entered into with us to indemnification by us against specific civil liabilities, including liabilities under the Securities Act. The agents may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

If we utilize any underwriters in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement with those underwriters at the time of sale to them. We will set forth the names of these underwriters and the terms of the transaction in the prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public. We may indemnify the underwriters under the relevant underwriting agreement against specific liabilities, including liabilities under the Securities Act. The underwriters may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

If we utilize a dealer in the sale of the securities in respect of which this prospectus is delivered, we will sell those securities to the dealer, as principal. The dealer may then resell those securities to the public at varying prices to be determined by the dealer at the time of resale. We may indemnify the dealers against specific liabilities, including liabilities under the Securities Act. The dealers may also be our customers or may engage in transactions with, or perform services for us in the ordinary course of business.

Common units, preferred units and debt securities may also be sold directly by us. In this case, no underwriters or agents would be involved. We may use electronic media, including the Internet, to sell offered securities directly.

Unless otherwise specified in the prospectus supplement, each series of the securities will be a new issue with no established trading market, other than the common units which are currently listed on the New York Stock Exchange. We may elect to list any series of debt securities or preferred units on an exchange, but are not obligated to do so. It is possible that one or more underwriters may make a market in a series of the securities, but underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, we can give no assurance about the liquidity of the trading market for any of the securities.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. The place and time of delivery for the securities in respect of which this prospectus is delivered are set forth in the accompanying prospectus supplement.
