PROXY STATEMENT FOR ANNUAL MEETING OF SHAREHOLDERS
To Be Held On May 15, 2008
 
QUESTIONS AND ANSWERS ABOUT THIS PROXY MATERIAL AND VOTING
 
Why am I receiving these materials?
 
We have sent you this proxy statement and the enclosed proxy card because the Board of Directors of Aradigm Corporation is soliciting your proxy to vote at the 2008 Annual Meeting of Shareholders. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card.
 
We intend to mail this proxy statement and accompanying proxy card on or about April 10, 2008 to all shareholders of record entitled to vote at the annual meeting.
 
Who can vote at the annual meeting?
 
Only shareholders of record at the close of business on March 31, 2008 will be entitled to vote at the annual meeting. On this record date, there were 54,776,455 shares of common stock outstanding and entitled to vote.
 
Shareholder of Record: Shares Registered in Your Name
 
If on March 31, 2008 your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are a shareholder of record. As a shareholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.
 
Beneficial Owner: Shares Registered in the Name of a Broker or Bank
 
If on March 31, 2008 your shares were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the shareholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.
 
What am I voting on?
 
There are five matters scheduled for a vote:
 
  •  Election of five directors;
 
  •  Approval of an amendment to Aradigm’s 2005 Equity Incentive Plan to increase the aggregate number of shares of common stock authorized for issuance under such plan by 2,700,000 shares;
 
  •  Approval of an amendment to Aradigm’s Employee Stock Purchase Plan (the “Purchase Plan”) to increase the aggregate number of shares of common stock authorized for issuance under such plan by 1,000,000 shares.
 
  •  Approval of an amendment to Aradigm’s Amended and Restated Articles of Incorporation to increase the authorized number of shares of common stock from 100,000,000 to 150,000,000; and
 
  •  Ratification of Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2008.


Table of Contents

 
How do I vote?
 
You may either vote “For” all the nominees for director or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:
 
Shareholder of Record: Shares Registered in Your Name
 
If you are a shareholder of record, you may vote in person at the annual meeting or vote by proxy using the enclosed proxy card. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy.
 
  •  To vote in person, come to the annual meeting and we will give you a ballot when you arrive.
 
  •  To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.
 
Beneficial Owner: Shares Registered in the Name of Broker or Bank
 
If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from Aradigm. Simply complete and mail the proxy card to ensure that your vote is counted. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.
 
How many votes do I have?
 
On each matter to be voted upon, you have one vote for each share of common stock you own as of March 31, 2008. However, you may be able to cumulate your votes for Proposal 1, the election of directors, if at least one shareholder gives notice at the meeting, before the voting, that he or she intends to cumulate votes. Under cumulative voting, you have five votes for each share of common stock you own. You may cast all of your votes for one candidate, or you may distribute your votes among different candidates as you choose. However, you may cumulate votes (cast more than one vote per share) for a candidate only if the candidate is nominated before the voting and at least one shareholder gives notice at the meeting, before the voting, that he or she intends to cumulate votes. If you do not specify how to distribute your votes, by giving your proxy you are authorizing the proxyholders (the individuals named on your proxy card) to cumulate votes in their discretion.
 
What if I return a proxy card but do not make specific choices?
 
If you return a signed and dated proxy card without marking any voting selections, your shares will be voted “For” the election of all five nominees for director, “For” the amendment to the 2005 Equity Incentive Plan, “For” the amendment to the Purchase Plan, “For” the amendment to our Amended and Restated Articles of Incorporation and “For” the ratification of Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2008. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.
 
Who is paying for this proxy solicitation?
 
We will pay for the entire cost of soliciting proxies. In addition to these mailed proxy materials, our directors and employees and Georgeson Shareholder Communications, Inc. (“Georgeson”) may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies, but Georgeson, if retained, would be paid its customary fee, estimated to be $8,500 plus out-of-pocket expenses, if it solicits proxies.

What does it mean if I receive more than one proxy card?
 
If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.
 
Can I change my vote after submitting my proxy?
 
Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of the shares, you may revoke your proxy in any one of three ways:
 
  •  You may submit another properly completed proxy card with a later date.
 
  •  You may send a timely written notice that you are revoking your proxy to our Secretary at 3929 Point Eden Way, Hayward, California, 94545.
 
  •  You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.
 
When are shareholder proposals due for next year’s annual meeting?
 
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 22, 2008, to our Secretary at 3929 Point Eden Way, Hayward, California, 94545. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director, you must do so no later than the close of business on March 16, 2009 and no earlier than the close of business on February 15, 2009. You are also advised to review our bylaws, which contain additional requirements about advance notice of shareholder proposals and director nominations. A copy of our bylaws is available via written request to our Secretary at 3929 Point Eden Way, Hayward, California, 94545, or by accessing EDGAR on the SEC’s website at www.sec.gov.
 
How are votes counted?
 
Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and (with respect to proposals other than the election of directors) “Against” votes, abstentions and broker non-votes. Abstentions and broker non-votes will not be counted towards the vote total for any proposal except Proposal 4. For Proposal 4, abstentions and broker non-votes will have the same effect as “Against” votes.
 
If your shares are held by your broker as your nominee (that is, in “street name”), you will need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker to vote your shares. If you do not give instructions to your broker, your broker can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. On non-discretionary items for which you do not give your broker instructions, the shares will be treated as broker non-votes.
 
What are broker non-votes?
 
Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine.” Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the New York Stock Exchange, “non-routine” matters are generally those involving a contest or a matter that may substantially affect the rights or privileges of shareholders, such as mergers or shareholder proposals.
 
How many votes are needed to approve each proposal?
 
  •  For the election of directors, the five nominees receiving the most “For” votes (from the holders of votes of shares present in person or represented by proxy and entitled to vote on the election of directors) will be elected. Broker non-votes will have no effect.

  •  To be approved, Proposal 2 (approval of an amendment to our 2005 Equity Incentive Plan to increase the aggregate number of shares of common stock authorized for issuance under such plan by 2,700,000 shares), must receive “For” votes from the holders of a majority of shares present either in person or by proxy and entitled to vote. Broker non-votes will have no effect.
 
  •  To be approved, Proposal 3 (approval of an amendment to our purchase plan to increase the aggregate number of shares of common stock authorized for issuance under such plan by 1,000,000 shares), must receive “For” votes from the holders of a majority of shares present either in person or by proxy and entitled to vote. Broker non-votes will have no effect.
 
  •  To be approved, Proposal 4 (approval of an amendment to our Amended and Restated Articles of Incorporation to increase the authorized number of shares of common stock from 100,000,000 to 150,000,000 shares) must receive “For” votes from the holders or a majority of the outstanding shares, either in person or by proxy. If you do not vote or you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have the same effect as “Against” votes.
 
  •  To be approved, Proposal 5 (ratifying the selection of Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2008) must receive “For” votes from the holders of a majority of shares present either in person or by proxy and entitled to vote. Abstentions and broker non-votes will have no effect.
 
What is the quorum requirement?
 
A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if shareholders holding a majority of the outstanding shares are present at the meeting in person or represented by proxy. On the record date, there were 54,776,455 shares of common stock outstanding and entitled to vote. Thus, the holders of 27,388,228 shares must be present in person or represented by proxy at the meeting or by proxy to have a quorum.
 
Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or vote at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of the shares present in person or represented by proxy at the meeting may adjourn the meeting to another date.
 
How can I find out the results of the voting at the annual meeting?
 
Preliminary voting results will be announced at the annual meeting. Final voting results will be published in our quarterly report on Form 10-Q for the second quarter of 2008.

PROPOSAL 1
ELECTION OF DIRECTORS
 
Our Board of Directors (the “Board”) currently consists of six directors. There are five nominees for director this year (Mr. Jaeger is not standing for reelection). Each director to be elected will hold office until the next annual meeting and until his successor is elected, or until the director’s death, resignation or removal. Each of the nominees listed below, except for Mr. Lynch, is currently a member of our Board who was previously elected by the shareholders. Mr. Lynch was recommended for election to the Board by our Nominating and Corporate Governance Committee and was appointed to the Board effective January 2, 2008. It is our policy to invite nominees to attend the annual meeting and to encourage attendance at meetings at which substantial shareholder attendance is expected. Four of the nominees for election as a director at the 2007 Annual Meeting of Shareholders attended the 2007 Annual Meeting of Shareholders.
 
The five candidates receiving the highest number of affirmative votes by the holders of shares entitled to be voted will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the five nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

THE BOARD OF DIRECTORS RECOMMENDS
A VOTE IN FAVOR OF EACH NAMED NOMINEE.
 
Independence of the Board of Directors
 
We have chosen to apply the listing standards of the Nasdaq Global Market (“Nasdaq”) in determining the independence of our directors. The Board consults with counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the Nasdaq, as in effect from time to time.
 
Consistent with these considerations, after review of all relevant transactions or relationships between each director and nominee for director, or any of his family members, and us, our senior management and our independent registered public accounting firm, the Board affirmatively has determined that the following four directors and nominees for directors are independent within the meaning of the applicable Nasdaq listing standards: Mr. Barker, Mr. Lynch, Dr. Siebert, and Mr. Thompson. In making this determination, the Board found that none of these directors or nominees for director had a material or disqualifying relationship with the Company. Dr. Gonda, our President and Chief Operating Officer, is not an independent director within the meaning of the applicable Nasdaq standards by virtue of his employment with Aradigm. In addition, each person who served as a director for any portion of 2007 was independent within the meaning of the applicable Nasdaq listing standards, except for Dr. Gonda.

Meetings of the Board of Directors
 
The Board held 12 meetings during the last fiscal year. Each of our current Board members attended 75% or more of the aggregate of the meetings of the Board and of the committees on which he served, held during the period for which he was a director or committee member, respectively.
 
In fiscal 2007 our independent directors met or held telephonic Board meetings 7 times in regularly scheduled executive sessions at which only independent directors were present. These meetings were chaired by Mr. Thompson, the Chairman of the Board. Persons interested in communicating with the independent directors with their concerns or issues may address correspondence to a particular director, or to the independent directors generally, in care of Aradigm at 3929 Point Eden Way, Hayward, California, 94545.
 
Shareholder Communications with the Board of Directors
 
We have implemented a process by which shareholders may communicate with the Board or any of its directors. Shareholders who wish to communicate with the Board may do so by sending written communications addressed to the Secretary of Aradigm at 3929 Point Eden Way, Hayward, California 94545. All communications will be compiled by our Secretary and submitted to the Board or the individual directors on a periodic basis. All communications directed to the Audit Committee in accordance with our whistleblower policy that relate to questionable accounting or auditing matters involving us will be forwarded directly to the Audit Committee.
 
Code of Ethics
 
We have adopted the Aradigm Corporation Code of Business Conduct and Ethics that applies to all of our officers, directors and employees. The Code of Business Conduct and Ethics is available on our website at www.aradigm.com. If we make any substantive amendments to the Code of Business Conduct and Ethics or grant any waiver from a provision of the Code to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website.

processes and audits of our financial statements. For this purpose, the Audit Committee performs several functions. The Audit Committee evaluates the performance of and assesses the qualifications of our independent registered public accounting firm; determines and approves the engagement of our independent registered public accounting firm; determines whether to retain or terminate the existing independent registered public accounting firm or to appoint and engage a new independent registered public accounting firm; reviews and approves the retention of the independent registered public accounting firm to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent registered public accounting firm on our audit engagement team as required by law; confers with management and our independent registered public accounting firm regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; reviews the financial statements to be included in our Annual Report on Form 10-K and our quarterly financial statements on Form 10-Q; and discusses with management and our independent registered public accounting firm the results of the annual audit. Currently, four directors comprise the Audit Committee: Messrs. Barker, Jaeger (chair), Lynch and Thompson. The Audit Committee is governed by a written charter that is available to shareholders on our website at www.aradigm.com.
 
The Board annually reviews the Nasdaq listing standards definition of independence for Audit Committee members and has determined that all members of our Audit Committee are independent (as independence is currently defined in Rule 4350(d)(2)(A)(i) and (ii) of the Nasdaq listing standards). The Board has determined that Messrs. Jaeger and Lynch each qualify as an “audit committee financial expert,” as defined in applicable rules of the Securities and Exchange Commission (the “SEC”). The Board made a qualitative assessment of Messrs. Jaeger and Lynch’s level of knowledge and experience based on a number of factors, including formal education and experience as a Chief Financial Officer for public reporting companies, as well as experience serving as the audit committee chairman for another publicly traded company.
 
Compensation Committee
 
The Compensation Committee of the Board reviews and recommends to the Board the overall compensation strategy and policies for us. The Compensation Committee reviews and recommends to the Board corporate performance goals and objectives relevant to the compensation of our executive officers and other senior management; reviews and recommends to the Board the compensation and other terms of employment of our Chief Executive Officer; reviews and recommends to the Board for approval the compensation and other terms of employment of the other officers; and oversees the administration of our stock option and purchase plans, pension and profit sharing plans, stock bonus plans, deferred compensation plans and other similar programs. Four directors currently comprise the Compensation Committee: Dr. Siebert and Messrs. Jaeger, Lynch and Thompson (chair). All members of our Compensation Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards). The Compensation Committee is governed by a written charter that is available to shareholders on our website at www.aradigm.com.
 
Nominating and Corporate Governance Committee
 
The Nominating and Corporate Governance Committee of the Board is responsible for identifying, reviewing and evaluating candidates to serve as directors (consistent with criteria approved by the Board), recommending to the Board candidates for election and re-election to the Board, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of the Board and its committees and monitoring compliance with the our Code of Business Conduct and Ethics. Currently, the Nominating and Corporate Governance Committee consists of three directors: Dr. Siebert and Messrs. Barker (chair) and Thompson. All current members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards). The Nominating and Corporate Governance Committee is governed by a written charter that is available to shareholders on our website at www.aradigm.com.
 
Any potential candidates for director nominees, including candidates recommended by shareholders, are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of shareholders. In conducting this assessment, the Committee considers such factors as it deems

appropriate given our current needs and those of our Board, to maintain a balance of knowledge, experience and capability. The Nominating and Corporate Governance Committee reviews directors’ overall service during their term, including the number of meetings attended, level of participation and quality of performance. The Committee also determines whether the nominee would be independent, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Committee then compiles a list of potential candidates from suggestions it may receive, but may also engage, if it deems appropriate, a professional search firm to generate additional suggestions. The Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates as it deems appropriate. The Committee meets to discuss and consider such candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote. In 2007 the Nominating and Corporate Governance Committee authorized the payment of a fee to a third party to assist in the process of identifying and evaluating director candidates. While the Committee and the Board have from time to time received and considered suggestions from shareholders for nominations to the Board, the Committee has received no suggestions for which disclosure is required in this proxy statement.
 
The Nominating and Corporate Governance Committee will consider director candidates recommended by shareholders. The Committee will consider candidates recommended by shareholders in the same manner as it considers recommendations from other sources. Shareholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 3929 Point Eden Way, Hayward, California 94545 at least 60 days prior, but no more than 90 days prior, to the anniversary date of the last annual meeting of shareholders. Submissions should include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating shareholder is a beneficial or record owner of our stock.

PROPOSAL 2
APPROVAL OF 2005 EQUITY INCENTIVE PLAN, AS AMENDED
 
In March 2005, the Board adopted, and our shareholders subsequently approved, the Aradigm Corporation 2005 Equity Incentive Plan (the “2005 Plan”), an amended, restated and retitled version of the Aradigm Corporation 1996 Equity Incentive Plan. As of March 31, 2008, a total of 6,518,638 shares of our common stock have been authorized for issuance under the 2005 Plan.
 
As of March 31, 2008, stock awards (net of canceled or expired stock awards) covering an aggregate of 911,592 shares of our common stock had been granted under the 2005 Plan, and 1,661,873 remained available for future grant under the 2005 Plan. During the 2006 fiscal year, under the 2005 Plan, we granted to all current executive officers as a group options to purchase 1,244,000 shares at a exercise prices of $1.29 to $3.77 per share and we granted to Dr. Gonda a stock bonus award pursuant to which he may receive up to 100,000 shares. During the same period we granted to all employees and directors (excluding current executive officers) as a group options to purchase 1,254,000 shares at exercise prices of $1.02 to $3.77 per share and restricted stock bonus awards to receive up to 90,467 shares (net of canceled or expired awards). During the 2007 fiscal year, under the 2005 Plan, we granted to all current executive officers as a group options to purchase 800,000 shares at a exercise prices of $1.37 to $1.60 per share and stock awards pursuant to which our current office as a group may receive up to 450,000 shares. During the same period we granted to all employees and directors (excluding current executive officers) as a group options to purchase 614,750 shares at exercise prices of $1.23 to $1.60 per share and restricted stock bonus awards to receive up to 271,125 shares (net of canceled or expired awards).
 
In March 2008, the Board adopted an amendment to the 2005 Plan, subject to shareholder approval, to increase the number of shares authorized for issuance under the 2005 Plan by 2,700,000 shares to 9,218,638 shares. This amendment is intended to afford us greater flexibility in providing employees with stock incentives and ensures that we can continue to provide such incentives at levels determined appropriate by the Board.
 
The following summary description of the 2005 Plan, as amended, is qualified in its entirety by reference to the full text of the 2005 Plan that is attached as Appendix A to the proxy statement filed via EDGAR with the SEC, including all changes that this proposal would effect if approved by our shareholders at the annual meeting.
 
Shareholders are requested in this Proposal 2 to approve the amendment to the 2005 Plan. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) will be required to approve the amendment to the 2005 Plan. For purposes of this vote, abstentions and broker non-votes will not be counted for any purpose in determining whether this matter has been approved.
 
THE BOARD OF DIRECTORS RECOMMENDS
A VOTE IN FAVOR OF PROPOSAL 2.
 
The essential features of the 2005 Plan are outlined below:
 
General
 
The 2005 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock purchase awards, stock bonus awards, stock unit awards, stock appreciation rights and other forms of equity compensation (collectively, the “stock awards”). Incentive stock options granted under the 2005 Plan are intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, or the “Code.” Nonstatutory stock options granted under the 2005 Plan are not intended to qualify as incentive stock options under the Code. See “Federal Income Tax Information” for a discussion of the tax treatment of stock awards. To date, the Company has granted stock options and stock bonus awards under the 2005 Plan.
 
Purpose
 
We adopted the 2005 Plan to provide a means by which selected officers, directors, employees of and consultants to us and our affiliates could be given an opportunity to acquire an equity interest in Aradigm


10


Table of Contents

Corporation, to assist in retaining the services of employees holding key positions, to secure and retain the services of persons capable of filling such positions and to provide incentives for such persons to exert maximum efforts for our success. As of March 31, 2008, approximately 67 employees, directors and consultants are eligible to participate in the 2005 Plan.
 
Administration
 
The Board administers the 2005 Plan. Subject to the provisions of the 2005 Plan, the Board has the authority to construe and interpret the plan, to determine the persons to whom and the dates on which stock awards will be granted, the type of stock award to grant to such person, the number of shares of common stock to be subject to each stock award, the time or times during the term of each stock award within which all or a portion of the award may be exercised, the exercise, purchase, or strike price of each stock award, the type of consideration permitted to exercise or purchase each stock award, and other terms of the stock awards.
 
The Board is authorized to delegate administration of the 2005 Plan to a committee composed of not fewer than two members of the Board. The Board has delegated administration of the 2005 Plan to the Compensation Committee of the Board. As used herein with respect to the 2005 Plan, the “Board” refers to the Compensation Committee as well as to the Board itself. In the Board’s discretion, directors serving on the Compensation Committee will be “outside directors” within the meaning of Section 162(m) of the Code (“Section 162(m)”). See “Federal Income Tax Information” for a discussion of the application of Section 162(m).
 
The Board may also delegate to one or more of our officers the authority to designate officers and employees to be recipients of stock awards and the terms thereof and/or determine the number of shares of our Common Stock to be subject to the stock awards granted to such officers and employees, so long as the Board resolution delegating such authority specifies the total number of shares of common stock underlying stock awards that the officer may grant, the officer does not grant any stock awards to himself or herself and the Board does not delegate the authority to determine the fair market value on the date of grant of the common stock underlying the stock awards.
 
Eligibility
 
Incentive stock options may be granted under the 2005 Plan only to our employees (including officers) and our affiliates. Employees, non-employee Board members and consultants of us and our affiliates are eligible to receive all other types of stock awards under the 2005 Plan.
 
No incentive stock option may be granted under the 2005 Plan to any person who, at the time of the grant, owns (or is deemed to own) stock possessing more than 10% of our total combined voting power or its affiliates, unless the exercise price of such option is at least 110% of the fair market value of the stock subject to the option on the date of grant and the term of the option does not exceed five years from the date of grant. In addition, the aggregate fair market value, determined on the date of grant, of the shares of common stock with respect to which incentive stock options are exercisable for the first time by a participant during any calendar year (under the 2005 Plan and any of our other plans and those of our affiliates) may not exceed $100,000.
 
No employee may be granted stock awards under the 2005 Plan exercisable for more than 1,500,000 shares of common stock during any calendar year.
 
Stock Subject to the 2005 Plan
 
Subject to this Proposal, an aggregate of 9,218,638 shares of common stock are reserved for issuance under the 2005 Plan. This share reserve consists of the number of shares we estimate will be carried over from the 1996 Plan, including shares subject to outstanding options under such predecessor plan, plus the additional shares that are the subject of Proposal 2. If stock awards granted under the 2005 Plan expire or otherwise terminate without being exercised or if we reacquire shares of common stock pursuant to the terms of unvested stock awards, the shares of common stock not acquired pursuant to such stock awards again become available for issuance under the 2005 Plan (provided, however, that any shares of common stock reacquired pursuant to incentive stock option awards will again become available for reissuance only for awards other than incentive stock options). If any shares of common stock subject to a stock award are not delivered because such shares are withheld for payment of taxes or because

Table of Contents

such shares are tendered as consideration for the exercise price of a stock award, the shares of common stock not delivered pursuant to such stock awards again become available for issuance under the 2005 Plan; provided, however, that any shares of common stock not delivered pursuant to incentive stock option awards will again become available for reissuance only for awards other than incentive stock options.
 
Terms of Options
 
The following is a description of the permissible terms of options under the 2005 Plan. Individual stock option agreements may be more restrictive as to any or all of the permissible terms described below.
 
Exercise Price.  The exercise price of incentive stock options under the 2005 Plan may not be less than the fair market value of our common stock subject to the option on the date of the option grant, and in some cases (see “Eligibility” above), may not be less than 110% of such fair market value. The exercise price of nonstatutory options under the 2005 Plan may not be less than 100% of the fair market value of our common stock subject to the option on the date of the option grant. At March 31, 2008, the closing price of our common stock as quoted on the OTC Bulletin Board, an electronic quotation service for securities traded over-the-counter, was $1.11 per share.
 
Consideration.  The exercise price of options granted under the 2005 Plan must be paid either in cash at the time the option is exercised or, at the discretion of the Board, (i) pursuant to a broker-assisted “same-day sale”, (ii) by delivery of other shares of our common stock, (iii) pursuant to a deferred payment arrangement or (iv) in any other form of legal consideration acceptable to the Board.
 
Restrictions on Repricing.  Under the terms of the 2005 Plan, the Board does not have the authority to reprice any outstanding stock awards under the 2005 Plan or cancel and re-grant any outstanding stock awards under the 2005 Plan, unless our shareholders have approved such an action within 12 months prior to such an event.
 
Vesting.  Options granted under the 2005 Plan may become exercisable in cumulative increments, or “vest,” as determined by the Board. Shares covered by currently outstanding options under the 2005 Plan typically vest at the rate of 25% per year during the optionee’s employment or services as a consultant or director. Shares covered by options granted in the future under the 2005 Plan may be subject to different vesting terms. The Board has the authority to accelerate the time during which an option may vest. In addition, options granted under the 2005 Plan may permit exercise prior to vesting. However, any unvested shares acquired under such an early exercise arrangement may be subject to repurchase by us or to any other restriction the Board determines to be appropriate. To the extent provided by the terms of an option, a participant may satisfy any federal, state or local tax withholding obligation relating to the exercise of such option by a cash payment upon exercise, by authorizing us to withhold a portion of the stock otherwise issuable to the participant or by such other method as the Board determines to include in the stock award agreement.
 
Term.  The Board has the discretion to determine the term of an option. However, the maximum term of an incentive stock option granted under the 2005 Plan is 10 years, except that in certain cases (see “Eligibility” above) the maximum permitted term of such award is five years. Options under the 2005 Plan terminate three months after termination of the participant’s service unless (i) such termination is due to the participant’s permanent and total disability (as defined in the Code), in which case the option may be exercised (to the extent the option was exercisable at the time of the termination of service) at any time within 12 months of such termination, unless the option agreement provides otherwise; (ii) the participant dies before the participant’s service has terminated, or within a certain period after termination of service, in which case the option may be exercised (to the extent the option was exercisable at the time of the participant’s death) within 18 months of the participant’s death by the person or persons to whom the rights to such option pass by will or by the laws of descent and distribution, unless the option agreement provides otherwise; or (iii) the option by its terms specifically provides otherwise. In no event, however, may an option be exercised beyond the expiration of its term.
 
A participant’s option agreement may provide that if the exercise of the option following the termination of the participant’s service would be prohibited because the issuance of stock would violate the registration requirements under the Securities Act, then the option will terminate on the earlier of (i) the expiration of the term of the option or (ii) three months after the termination of the participant’s service during which the exercise of the option would not be in violation of such registration requirements.

Restrictions on Transfer.  Unless specified otherwise by the Board or required by law, a participant in the 2005 Plan may not transfer a stock option other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. During the lifetime of the participant, only the participant may exercise a stock option. A participant may designate a beneficiary who may exercise an option following the participant’s death. Shares subject to repurchase by us pursuant to an early exercise arrangement may be subject to restrictions on transfer that the Board deems appropriate.
 
Terms of Stock Purchase Awards and Stock Bonus Awards
 
Stock purchase awards and stock bonus awards may be granted under the 2005 Plan pursuant to stock purchase award agreements and stock bonus award agreements, respectively.
 
Purchase Price.  The purchase price for stock purchase awards must be at least the par value of our common stock.
 
Consideration.  The purchase price for stock purchase awards may be paid in cash, or, at the discretion of the Board, under a deferred payment or similar arrangement, by past services rendered to us or in any other form of legal consideration acceptable to the Board and permissible under applicable law. The Board may grant stock bonus awards in consideration for past services rendered to us or any other form of legal consideration acceptable to the Board and permissible under applicable law.
 
Vesting.  Shares of stock acquired under a stock purchase may, but need not, be subject to a repurchase right or option in our favor; and shares of stock acquired under a stock bonus award may, but need not, be subject to forfeiture to us in accordance with a vesting schedule as determined by the Board. The Board has the authority to accelerate the vesting of stock acquired pursuant to a stock purchase or stock bonus award.
 
Termination of Service.  Upon termination of a participant’s service, we may repurchase or otherwise reacquire any forfeited shares of stock that have not vested as of such termination under the terms of the applicable stock purchase award or stock bonus award agreement.
 
Restrictions on Transfer.  Rights to acquire shares under a stock purchase or stock bonus award may be transferred only upon such terms and conditions as may be approved by the Board.
 
Terms of Stock Unit Awards
 
Stock unit awards may be granted under the 2005 Plan pursuant to stock unit award agreements.
 
Consideration.  The purchase price for stock unit awards may be paid in any form of legal consideration acceptable to the Board.
 
Settlement of Awards.  A stock unit award may be settled by the delivery of shares of our Common Stock, cash, in any combination of the two or in any other form of consideration, as determined by the Board.
 
Vesting.  At the time of the grant of a stock unit, the Board may impose such restrictions or conditions to the vesting of the stock unit as it, in its sole discretion, deems appropriate. Also, at the time of grant, the Board may impose additional restrictions or conditions that delay the delivery of stock or cash subject to the stock unit award after vesting. The Board has the authority to accelerate the vesting of stock unit awards as it deems appropriate.
 
Dividend Equivalents.  Dividend equivalent rights may be credited with respect to shares covered by a stock unit award, as determined by the Board. We do not anticipate paying cash dividends on our Common Stock for the foreseeable future.
 
Termination of Service.  Except as otherwise provided in the applicable award agreement, stock units that have not vested will be forfeited upon the participant’s termination of service.
 
Terms of Stock Appreciation Rights
 
Stock appreciation rights may be granted under the 2005 Plan pursuant to stock appreciation rights agreements.


13


Table of Contents

Exercise.  Each stock appreciation right is denominated in shares of common stock equivalents. Upon exercise of a stock appreciation right, we will pay the participant an amount equal to the excess of (i) the aggregate fair market value on the date of exercise of a number of common stock equivalents with respect to which the participant is exercising the stock appreciation right over (ii) the strike price on the date of grant, as determined by the Board.
 
Settlement of Awards.  The appreciation distribution upon exercise of a stock appreciation right may be paid in cash, in shares of our common stock, in any combination of the two or in any other form of consideration determined by the Board.
 
Vesting.  The Board may impose such conditions and restrictions as to the vesting of stock appreciation rights as it deems appropriate. The Board has the authority to accelerate the vesting of stock appreciation rights as it deems appropriate.
 
Termination of Service.  Upon termination of a participant’s service, the participant generally may exercise any vested stock appreciation right for three months (or such longer or shorter period specified in the stock appreciation right agreement) after the date such service relationship ends. In no event may a stock appreciation right be exercised beyond the expiration of its term.
 
Terms of Other Equity Awards
 
The Board may grant other equity awards based in whole or in part by reference to the value of our common stock. See the full text of the 2005 Plan, set forth in Appendix A to the Proxy Statement filed via EDGAR with the SEC, for more details. Subject to the provisions of the 2005 Plan, the Board has the authority to determine the persons to whom and the dates on which such other equity awards will be granted, the number of shares of common stock (or cash equivalents) to be subject to each award, and other terms and conditions of such awards.
 
Performance-Based Stock Awards
 
Under the 2005 Plan, a stock award may be granted, vest or be exercised based upon the attainment during a certain period of time of certain performance goals. All employees of and consultants to us and our affiliates and directors are eligible to receive performance-based stock awards under the 2005 Plan. The length of any performance period, the performance goals to be achieved during the performance period, and the measure of whether and to what degree such performance goals have been attained shall be determined by the Board. The maximum benefit to be received by any individual in any calendar year attributable to performance-based stock awards may not exceed the value of 500,000 shares of our common stock.
 
In granting a performance-based stock award, the Board will set a period of time (a “performance period”) over which the attainment of one or more goals (“performance goals”) will be measured for the purpose of determining whether the award recipient has a vested right in or to such award. Within the time period prescribed by Section 162(m) of the Code (typically before the 90th day of a performance period), the Board will establish the performance goals, based upon one or more pre-established criteria (“performance criteria”) enumerated in the 2005 Plan and described below. As soon as administratively practicable following the end of the performance period, the Board will certify (in writing) whether the performance goals have been satisfied.
 
Performance goals under the 2005 Plan shall be determined by the Board, based on one or more of the following performance criteria: (i) earnings per share; (ii) earnings before interest, taxes and depreciation; (iii) earnings before interest, taxes, depreciation and amortization (EBITDA); (iv) net earnings; (v) total shareholder return; (vi) return on equity; (vii) return on assets, investment or capital employed; (viii) operating margin; (ix) gross margin; (x) operating income; (xi) net income (before or after taxes); (xii) net operating income; (xiii) net operating income after tax; (xiv) pre- and after-tax income; (xv) pre-tax profit; (xvi) operating cash flow; (xvii) sales or revenue targets; (xviii) increases in revenue or product revenue; (xix) expenses and cost reduction goals; (xx) improvement in or attainment of expense levels; (xxi) improvement in or attainment of working capital levels; (xxii) economic value added (or an equivalent metric); (xxiii) market share; (xxiv) cash flow; (xxv) cash flow per share; (xxvi) share price performance; (xxvii) debt reduction; (xxviii) implementation or completion of projects or processes; (xxix) customer satisfaction; (xxx) total shareholder return; (xxxi) shareholders’ equity; and (xxxii) to

Table of Contents

the extent that an award is not intended to comply with Section 162(m) of the Code, other measures of performance selected by the Board.
 
The Board is authorized to adjust or modify the calculation of a performance goal for a performance period in order to prevent the dilution or enlargement of the rights of participants, (a) in the event of, or in anticipation of, any unusual or extraordinary corporate item, transaction, event or development; (b) in recognition of, or in anticipation of, any other unusual or nonrecurring events affecting us, or our financial statements, or in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions; or (c) in view of the Board’s assessment of our business strategy, performance of comparable organizations, economic and business conditions, and any other circumstances deemed relevant. Specifically, the Board is authorized to make adjustment in the method of calculating attainment of performance goals and objectives for a performance period as follows: (i) to exclude the dilutive effects of acquisitions or joint ventures; (ii) to assume that any business we divested achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; and (iii) to exclude the effect of any change in the outstanding shares of our common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common shareholders other than regular cash dividends. In addition, the Board is authorized to make adjustment in the method of calculating attainment of performance goals and objectives for a performance period as follows: (i) to exclude restructuring and/or other nonrecurring charges; (ii) to exclude exchange rate effects, as applicable, for non-U.S. dollar denominated net sales and operating earnings; (iii) to exclude the effects of changes to generally accepted accounting standards required by the Financial Accounting Standards Board; (iv) to exclude the effects to any statutory adjustments to corporate tax rates; (v) to exclude the impact of any “extraordinary items” as determined under generally accepted accounting principles; and (vi) to exclude any other unusual, non-recurring gain or loss or other extraordinary item.
 
Changes to Capital Structure
 
In the event any change is made to the outstanding shares of our common stock without our receipt of consideration (whether through a stock split or other specified change in our capital structure), appropriate adjustments will be made to: (i) the maximum number and/or class of securities issuable under the 2005 Plan; (ii) the maximum number and/or class of securities issuable as incentive stock options under the 2005 Plan; (iii) the maximum number and/or class of securities for which any one person may be granted options and/or stock appreciation rights or performance-based awards per calendar year pursuant to the limitation under Section 162(m); and (iv) the number and/or class of securities and the price per share in effect under each outstanding stock award under the 2005 Plan.
 
Effect of Certain Corporate Events
 
In the event of our dissolution or liquidation, any stock award which remains unvested or subject to a right or repurchase shall terminate immediately prior to such liquidation or dissolution and the shares of common stock subject to such repurchase right may be repurchased by us notwithstanding that that the holder of such award is providing service to us. The Board may, in its discretion, cause some or all stock awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture before the liquidation or dissolution is completed, but contingent on its completion.
 
In the event of certain significant corporate transactions, all outstanding stock awards under the 2005 Plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume, continue or substitute such stock awards, then (i) with respect to any such stock awards that are held by individuals then performing services for us or our affiliates, the vesting and exercisability provisions of such stock awards will be accelerated in full and such awards will be terminated if not exercised prior to the effective date of the corporate transaction; and (ii) all other outstanding stock awards will be terminated if not exercised prior to the effective date of the corporate transaction.
 
A significant corporate transaction will be deemed to occur in the event of (i) a sale or all or substantially all of our consolidated assets and those of our subsidiaries, (ii) the sale of at least 90% of our outstanding securities, (iii) a


15

merger or consolidation in which we are not the surviving corporation or (iv) a merger, consolidation or similar transaction in which we are the surviving corporation, but shares of our outstanding common stock are converted into other property by virtue of the transaction.
 
Following certain specified change in control transactions, the vesting and exercisability of specified stock awards will be accelerated only if specifically provided by a participant’s award agreement. The acceleration of a stock award in the event of certain significant corporate transactions or a change in control may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of us.
 
Duration, Termination and Amendment
 
The Board may suspend or terminate the 2005 Plan without shareholder approval or ratification at any time. Unless sooner terminated, the 2005 Plan will terminate on March 20, 2015.
 
The Board may amend the 2005 Plan at any time or from time to time. However, no amendment will be effective unless approved by our shareholders if the amendment would (i) modify the requirements as to eligibility for participation (to the extent such modification requires shareholder approval in order for the 2005 Plan to satisfy Section 422 of the Code, if applicable, or Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)); (ii) increase the number of shares reserved for issuance upon exercise of awards; or (iii) change any other provision of the 2005 Plan in any other way if such modification requires shareholder approval in order to comply with Rule 16b-3 of the Exchange Act or satisfy the requirements of Section 422 of the Code or any securities exchange listing requirements. The Board may submit any other amendment to the 2005 Plan for shareholder approval, including, but not limited to, amendments intended to satisfy the requirements of Section 162(m) regarding the exclusion of performance-based compensation from the limitation on the deductibility of compensation paid to certain employees.
 
Federal Income Tax Information
 
The following is a summary of the principal United States federal income taxation consequences to employees and us with respect to participation in the 2005 Plan. This summary is not intended to be exhaustive, and does not discuss the income tax laws of any city, state or foreign jurisdiction in which a participant may reside.
 
Incentive Stock Options.  Incentive stock options granted under the 2005 Plan are intended to be eligible for the favorable federal income tax treatment accorded “incentive stock options” under the Code. There generally are no federal income tax consequences to the participant or us by reason of the grant or exercise of an incentive stock option. However, the exercise of an incentive stock option may give rise to or increase alternative minimum tax liability for the participant.
 
If a participant holds stock acquired through exercise of an incentive stock option for more than two years from the date on which the option was granted and more than one year after the date the option was exercised for those shares, any gain or loss on a disposition of those shares (a “qualifying disposition”) will be a long-term capital gain or loss. Upon such a qualifying disposition, we will not be entitled to any income tax deduction.
 
Generally, if the participant disposes of the stock before the expiration of either of these holding periods (a “disqualifying disposition”), then at the time of disposition the participant will realize taxable ordinary income equal to the lesser of (i) the excess of the stock’s fair market value on the date of exercise over the exercise price or (ii) the participant’s actual gain, if any, on the purchase and sale. The participant’s additional gain or any loss upon the disqualifying disposition will be a capital gain or loss, which will be long-term or short-term depending on whether the stock was held for more than one year.
 
To the extent the participant recognizes ordinary income by reason of a disqualifying disposition, generally we will be entitled (subject to the requirement of reasonableness, the provisions of Section 162(m), and the satisfaction of a tax reporting obligation) to a corresponding income tax deduction in the tax year in which the disqualifying disposition occurs.


16


Table of Contents

Nonstatutory Stock Options, Restricted Stock Purchase Awards and Stock Bonuses.  There generally are no tax consequences to the participant or us by reason of the grant of these awards. Upon acquisition of the stock under any of these awards, the participant normally will recognize taxable ordinary income equal to the excess, if any, of the stock’s fair market value on the acquisition date over the purchase price. However, to the extent the stock is subject to certain types of vesting restrictions, the taxable event will be delayed until the vesting restrictions lapse unless the participant elects to be taxed on receipt of the stock under Section 83(b) of the Code. With respect to employees, we are generally required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) and the satisfaction of a tax reporting obligation, we will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the participant.
 
Upon disposition of the stock, the participant will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock plus any amount recognized as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss will be long-term or short-term depending on whether the stock was held for more than one year. Slightly different rules may apply to participants who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Exchange Act.
 
Stock Unit Awards.  No taxable income is generally recognized upon receipt of a stock unit award. The participant will recognize ordinary income in the year in which the shares subject to that unit are actually issued to the participant in an amount equal to the fair market value of the shares on the date of issuance. We and the participant will be required to satisfy certain tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant at the time the shares are issued. In general, the deduction will be allowed for the taxable year in which such ordinary income is recognized by the participant. Section 409A of the Code may apply to the grant of a stock unit award if the award permits the participant to defer receipt of the stock after vesting, unless a deferral election and certain other requirements are met.
 
Stock Appreciation Rights.  No taxable income is realized upon the receipt of a stock appreciation right. Upon exercise of the stock appreciation right, the fair market value of the shares (or cash in lieu of shares) received is recognized as ordinary income to the participant in the year of such exercise. Generally, with respect to employees, we are required to withhold from the payment made on exercise of the stock appreciation right or from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, Section 162(m) and the satisfaction of a reporting obligation, we will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant.
 
Potential Limitation on Company Deductions.  Section 162(m) denies a deduction to any publicly held corporation for compensation paid to certain “covered employees” in a taxable year to the extent that compensation to such covered employee exceeds $1 million. It is possible that compensation attributable to awards, when combined with all other types of compensation received by a covered employee from us, may cause this limitation to be exceeded in any particular year.
 
Certain kinds of compensation, including qualified “performance-based compensation,” are disregarded for purposes of the deduction limitation. In accordance with Treasury Regulations issued under Section 162(m), compensation attributable to stock options and stock appreciation rights will qualify as performance-based compensation if the award is granted by a compensation committee comprised solely of “outside directors” and either (i) the plan contains a per-employee limitation on the number of shares for which such awards may be granted during a specified period, the per-employee limitation is approved by the shareholders, and the exercise price of the award is no less than the fair market value of the stock on the date of grant or (ii) the award is granted (or exercisable) only upon the achievement (as certified in writing by the compensation committee) of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain, and the award is approved by shareholders.
 
Stock purchase awards, stock units and stock bonus awards will qualify as performance-based compensation under the Treasury Regulations only if (i) the award is granted by a compensation committee comprised solely of “outside directors,” (ii) the award is granted (or exercisable) only upon the achievement of an objective performance goal established in writing by the compensation committee while the outcome is substantially uncertain, (iii) the

compensation committee certifies in writing prior to the granting (or exercisability) of the award that the performance goal has been satisfied and (iv) prior to the granting (or exercisability) of the award, shareholders have approved the material terms of the award (including the class of employees eligible for such award, the business criteria on which the performance goal is based, and the maximum amount — or formula used to calculate the amount — payable upon attainment of the performance goal). The Company intends to comply with these regulations with respect to performance-based compensation that it may award.
 
New Plan Benefits
 
Since benefits under the 2005 Plan will depend on the individuals selected at the discretion of the Board and/or the Compensation Committee to receive awards, the number of shares to be awarded and the fair market value of our common stock at various future dates, it is not possible at this time to determine the benefits that will be received under the 2005 Plan by all eligible employees, officers, directors or consultants.

PROPOSAL 3
APPROVAL OF EMPLOYEE STOCK PURCHASE PLAN, AS AMENDED
 
In April 1996, the Board of Directors adopted, and the shareholders subsequently approved, the Purchase Plan. A total of 1,050,000 shares of the Company’s Common Stock have previously been authorized for issuance under the Purchase Plan. At March 31, 2008, an aggregate of 809,560 shares had been issued under the Purchase Plan and 240,440 shares remained for the grant of future rights under the Purchase Plan.
 
During the last fiscal year, shares were purchased at prices ranging from $1.02 to $1.04 in the following amounts under the Purchase Plan: all current executive officers as a group (33,318 shares), and all employees (excluding current executive officers) as a group (67,089 shares).
 
In April 2008, the Board of Directors of the Company adopted an amendment to the Purchase Plan, subject to shareholder approval, to increase the number of shares authorized for issuance under the Purchase Plan by 1,000,000 to 2,050,000 shares. This amendment is intended to afford the Company greater flexibility in providing employees with stock incentives and ensures that the Company can continue to provide such incentives at levels determined appropriate by the Board.
 
The following summary description of the Purchase Plan, as amended, is qualified in its entirety by reference to the full text of the Purchase Plan that is attached as Appendix B to the proxy statement filed via EDGAR with the SEC, including all changes that this proposal would effect if approved by our shareholders at the annual meeting.
 
Shareholders are requested in this Proposal 3 to approve the Purchase Plan, as amended. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) will be required to approve the Purchase Plan, as amended. For purposes of this vote abstentions and broker non-votes will not be counted for any purpose in determining whether this matter has been approved.
 
THE BOARD OF DIRECTORS RECOMMENDS
A VOTE IN FAVOR OF PROPOSAL 3.
 
The essential features of the Purchase Plan, as amended, are outlined below:
 
Purpose
 
The purpose of the Purchase Plan is to provide a means by which key employees of the Company (and any parent or subsidiary of the Company designated by the Board of Directors to participate in the Purchase Plan) may be given an opportunity to purchase Common Stock of the Company through payroll deductions, to assist the Company in retaining the services of its employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for the success of the Company. At March 31, 2008, all of the Company’s approximately 51 employees were eligible to participate in the Purchase Plan
 
The rights to purchase Common Stock granted under the Purchase Plan are intended to qualify as options issued under an “employee stock purchase plan” as that term is defined in Section 423(b) of the Code.
 
Administration
 
The Purchase Plan is administered by the Board of Directors, which has the final power to construe and interpret the Purchase Plan and the rights granted under it. The Board has the power, subject to the provisions of the Purchase Plan, to determine when and how rights to purchase Common Stock of the Company will be granted, the provisions of each offering of such rights (which need not be identical), and whether any parent or subsidiary of the Company shall be eligible to participate in such plan. The Board has the power, which it has not exercised, to delegate administration of such plan to a committee of not less than two Board members. The Board may abolish any such committee at any time and revest in itself the administration of the Purchase Plan.

Table of Contents

Offerings
 
The Purchase Plan is implemented by offerings of rights to all eligible employees from time to time by the Board. Generally, each such offering is two years in duration. The Board may set the duration of an offering for a period of time not to exceed 27 months.
 
Eligibility
 
Any person who is customarily employed at least 20 hours per week and five months per calendar year by the Company (or by any parent or subsidiary of the Company designated from time to time by the Board) on the first day of an offering period is eligible to participate in that offering under the Purchase Plan, provided such employee has been in the continuous employ of the Company for at least 10 days preceding the first day of the offering period.
 
Notwithstanding the foregoing, no employee is eligible for the grant of any rights under the Purchase Plan if, immediately after such grant, the employee would own, directly or indirectly, stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any parent or subsidiary of the Company (including any stock which such employee may purchase under all outstanding rights and options), nor will any employee be granted rights that would permit him to buy more than $25,000 worth of stock (determined at the fair market value of the shares at the time such rights are granted) under all employee stock purchase plans of the Company in any calendar year.
 
Participation in the Plan
 
Eligible employees become participants in the Purchase Plan by delivering to the Company, prior to the date selected by the Board as the offering date for the offering, an agreement authorizing payroll deductions of up to 15% of such employees’ total compensation during the purchase period.
 
Purchase Price
 
The purchase price per share at which shares are sold in an offering under the Purchase Plan is the lower of (i) 85% of the fair market value of a share of Common Stock on the date of commencement of the offering, or (ii) 85% of the fair market value of a share of Common Stock on any purchase date.
 
Payment of Purchase Price; Payroll Deductions
 
The purchase price of the shares is accumulated by payroll deductions over the offering period. At any time during the purchase period, a participant may reduce or terminate his or her payroll deductions. A participant may not increase or begin such payroll deductions after the beginning of any purchase period, except, if the Board provides, in the case of an employee who first becomes eligible to participate as of a date specified during the purchase period. All payroll deductions made for a participant are credited to his or her account under the Purchase Plan and deposited with the general funds of the Company. A participant may not make any additional payments into such account.
 
Purchase of Stock
 
By executing an agreement to participate in the Purchase Plan, the employee is entitled to purchase shares under such plan. In connection with offerings made under the Purchase Plan, the Board specifies a maximum number of shares any employee may be granted the right to purchase and the maximum aggregate number of shares which may be purchased pursuant to such offering by all participants. If the aggregate number of shares to be purchased upon exercise of rights granted in the offering would exceed the maximum aggregate number, the Board would make a pro rata allocation of shares available in a uniform and equitable manner. Unless the employee’s participation is discontinued, his right to purchase shares is exercised automatically at the end of the purchase period at the applicable price. See “Withdrawal” below.


20


Table of Contents

Withdrawal
 
While each participant in the Purchase Plan is required to sign an agreement authorizing payroll deductions, the participant may withdraw from a given offering by terminating his or her payroll deductions and by delivering to the Company a notice of withdrawal from the Purchase Plan. Such withdrawal may be elected at any time prior to the end of the applicable offering period.
 
Upon any withdrawal from an offering by the employee, the Company will distribute to the employee his or her accumulated payroll deductions without interest, less any accumulated deductions previously applied to the purchase of stock on the employee’s behalf during such offering, and such employee’s interest in the offering will be automatically terminated. The employee is not entitled to again participate in such offering. An employee’s withdrawal from an offering will not have any effect upon such employee’s eligibility to participate in subsequent offerings under the Purchase Plan.
 
Termination of Employment
 
Rights granted pursuant to any offering under the Purchase Plan terminate immediately upon cessation of an employee’s employment for any reason, and the Company will distribute to such employee all of his or her accumulated payroll deductions, without interest.
 
Restrictions on Transfer
 
Rights granted under the Purchase Plan are not transferable and may be exercised only by the person to whom such rights are granted.
 
Duration, Amendment and Termination
 
The Board may, in its discretion, suspend or terminate the Purchase Plan at any time.
 
The Board may amend the Purchase Plan at any time. Any amendment of the Purchase Plan must be approved by the shareholders within 12 months of its adoption by the Board if the amendment would (i) increase the number of shares of Common Stock reserved for issuance under the Purchase Plan, (ii) modify the requirements relating to eligibility for participation in the Purchase Plan, or (iii) modify any other provision of the Purchase Plan in a manner that would materially increase the benefits accruing to participants under the Purchase Plan, if such approval is required in order to comply with the requirements of Rule 16b-3 under the Exchange Act.
 
Rights granted before amendment or termination of the Purchase Plan will not be altered or impaired by any amendment or termination of such plan without consent of the person to whom such rights were granted.
 
Effect of Certain Corporate Events
 
In the event of a dissolution, liquidation or specified type of merger of the Company, the surviving corporation either will assume the rights under the Purchase Plan or substitute similar rights, or the exercise date of any ongoing offering will be accelerated such that the outstanding rights may be exercised immediately prior to, or concurrent with, any such event.
 
Stock Subject to Purchase Plan
 
If rights granted under the Purchase Plan expire, lapse or otherwise terminate without being exercised, the Common Stock not purchased under such rights again becomes available for issuance under such plan.
 
Federal Income Tax Information
 
Rights granted under the Purchase Plan are intended to qualify for favorable federal income tax treatment associated with rights granted under an employee stock purchase plan which qualifies under provisions of Section 423 of the Code.


21


Table of Contents

A participant will be taxed on amounts withheld for the purchase of shares as if such amounts were actually received. Other than this, no income will be taxable to a participant until disposition of the shares acquired, and the method of taxation will depend upon the holding period of the purchased shares.
 
If the stock is disposed of at least two years after the beginning of the offering period and at least one year after the stock is transferred to the participant, then the lesser of (i) the excess of the fair market value of the stock at the time of such disposition over the purchase price or (ii) the excess of the fair market value of the stock as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period) will be treated as ordinary income. Any further gain or any loss will be taxed as a capital gain or loss. Capital gains currently are generally subject to lower tax rates than ordinary income.
 
If the stock is sold or disposed of before the expiration of either of the holding periods described above, then the excess of the fair market value of the stock on the purchase date over the purchase price will be treated as ordinary income at the time of such disposition, and the Company may, in the future, be required to withhold income taxes relating to such ordinary income from other payments made to the participant. The balance of any gain will be treated as capital gain. Even if the stock is later disposed of for less than its fair market value on the purchase date, the same amount of ordinary income is attributed to the participant, and a capital loss is recognized equal to the difference between the sales price and the fair market value of the stock on such purchase date.
 
There are no federal income tax consequences to the Company by reason of the grant or purchase of rights under the Purchase Plan. The Company is entitled to a deduction to the extent amounts are taxed as ordinary income to a participant (subject to the requirement of reasonableness, the provisions of Section 162(m) and the satisfaction of a tax reporting obligation).

PROPOSAL 4
APPROVAL OF CERTIFICATE OF AMENDMENT TO AMENDED AND RESTATED ARTICLES OF
INCORPORATION TO INCREASE IN NUMBER OF AUTHORIZED SHARES OF COMMON STOCK
 
The Board is requesting shareholder approval of an amendment to our Amended and Restated Articles of Incorporation to increase the authorized number of shares of common stock from 100,000,000 shares to 150,000,000 shares.
 
The additional common stock to be authorized by adoption of the amendment would have rights identical to the currently outstanding common stock of Aradigm. Adoption of the proposed amendment and issuance of the common stock would not affect the rights of the holders of currently outstanding common stock of Aradigm, except for effects incidental to increasing the number of shares of common stock outstanding, such as dilution of the earnings (loss) per share and voting rights of current holders of common stock. If the amendment is adopted, it will become effective upon filing of a Certificate of Amendment of our Amended and Restated Articles of Incorporation with the Secretary of State of the State of California.
 
In addition to the 54,772,705 shares of common stock outstanding on December 31, 2007, the Board has reserved 3,593,154 shares for issuance upon exercise of options and rights granted under our stock option and stock purchase plans, and up to 426,669 shares of common stock which may be issued upon exercise of warrants.
 
Although, at present the Board has no other plans to issue the additional shares of common stock, it desires to have the shares available to provide additional flexibility to use its capital stock for business and financial purposes in the future. The additional shares may be used for various purposes without further shareholder approval. These purposes may include: raising capital, providing equity incentives to employees, officers or directors, establishing strategic relationships with other companies, expanding the company’s business or product lines through the acquisition of other businesses or products, and other purposes.
 
We could also use the additional shares of common stock that would become available for issuance if the proposal were adopted to oppose a hostile takeover attempt or to delay or prevent changes in control or management of Aradigm. For example, without further shareholder approval, the Board could strategically sell shares of common stock in a private transaction to purchasers who would oppose a takeover or favor the current Board. Although this proposal to increase the authorized common stock has been prompted by business and financial considerations and not by the threat of any hostile takeover attempt (nor is the Board currently aware of any such attempts directed at Aradigm), nevertheless, shareholders should be aware that approval of proposal could facilitate future efforts by us to deter or prevent changes in control of Aradigm, including transactions in which Aradigm might otherwise receive a premium for their shares over then current market prices. For more information relating to opposition of a hostile takeover attempt or delay and prevention of changes in control or management, please see the paragraph entitled “We have implemented certain anti-takeover provisions” in the Risk Factors section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2007.
 
The affirmative vote of the holders of a majority of the outstanding shares of common stock will be required to approve this amendment to our Amended and Restated Articles of Incorporation. As a result, abstentions and broker non-votes will have the same effect as negative votes.

PROPOSAL 5
RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING
FIRM
 
The Audit Committee of the Board of Directors has selected Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2008 and has further directed that management submit the selection of an independent registered public accounting firm for ratification by our shareholders at the annual meeting. Prior to the selection of Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm in April 2007, Ernst & Young LLP had audited our financial statements, since 1995. Representatives of Odenberg, Ullakko, Muranishi & Co. LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
 
Neither our bylaws nor other governing documents or law require shareholder ratification of the selection of Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of Odenberg, Ullakko, Muranishi & Co. LLP to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Aradigm and its shareholders.
 
The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the annual meeting (which shares voting affirmatively also constitute a majority of the required quorum) will be required to ratify the selection of Odenberg, Ullakko, Muranishi & Co. LLP. For purposes of this vote, abstentions and broker non-votes will not be counted for any purpose in determining whether this matter has been approved.
 
Principal Accountant Fees and Services
 
The following table represents aggregate fees billed to us for fiscal years ended December 31, 2007, and December 31, 2006, by Odenberg, Ullakko, Muranishi & Co. LLP and Ernst & Young LLP, our independent registered public accounting firm for each of those years, respectively. All services described below were pre-approved by the Audit Committee.

Pre-Approval Policies and Procedures
 
The Audit Committee pre-approves audit services, audit-related services and non-audit services provided by our independent registered public accounting firm, Odenberg, Ullakko, Muranishi & Co. LLP, and will not approve services that the Audit Committee determines are outside the bounds of applicable laws and regulations. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual explicit case-by-case basis before the independent registered public accounting firm is engaged to provide each service. The pre-approval of services may be

delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.
 
The Audit Committee has determined that the rendering of the services, other than audit services, by Odenberg, Ullakko, Muranishi & Co. LLP is compatible with maintaining the principal accountant’s independence.
 
Change in Independent Registered Public Accounting Firm
 
Effective as of April 12, 2007, the Audit Committee dismissed Ernst & Young LLP as our independent registered public accounting firm. On the same date, the Audit Committee engaged Odenberg, Ullakko, Muranishi & Co. LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2007.
 
The audit reports of Ernst & Young LLP on our financial statements for the fiscal years ended December 31, 2005 and 2006 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with Ernst & Young LLP’s audits for the fiscal years ended December 31, 2005 and 2006, and in the subsequent interim period through April 12, 2007, there were no disagreements with Ernst & Young LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Ernst & Young LLP, would have caused Ernst & Young LLP to make reference to the subject matter of such disagreements in connection with its reports. In addition no reportable events, as defined in Item 304(a)(1)(v) of Regulation S-K, occurred during our fiscal years ended December 31, 2005 and 2006, and in the subsequent interim period through April 12, 2007. Ernst & Young LLP’s letter to the Securities and Exchange Commission stating its agreement with the statements in this paragraph is filed as an exhibit to our Current Report on Form 8-K filed with the Securities and Exchange Commission on April 17, 2007.
 
Prior to April 12, 2007, neither we nor anyone on our behalf has consulted with Odenberg, Ullakko, Muranishi & Co. LLP regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements, and neither a written report was provided to us nor oral advice was provided by Odenberg, Ullakko, Muranishi & Co. LLP that was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement, as that term is defined in Item 304 (a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a reportable event, as that term is defined in Item 304 (a)(1)(v) of Regulation S-K.

COMPENSATION
 
The policies of the Compensation Committee, or the Committee, with respect to the compensation of executive officers, including the Chief Executive Officer, or CEO, are designed to provide compensation sufficient to attract, motivate and retain executives of outstanding ability and potential and to establish an appropriate relationship between executive compensation and the creation of shareholder value. To meet these goals, the Committee recommends executive compensation packages to our board of directors that are based on a mix of salary, bonus and equity awards.
 
Overall, the board and the Committee seek to provide total compensation packages that are competitive in terms of total potential value to our executives, and that are tailored to the unique characteristics of our company in order to create an executive compensation program that will adequately reward our executives for their roles in creating value for our shareholders. The board and the Committee intend to provide executive compensation packages that are competitive with other similarly situated companies in our industry. The board and the Committee generally weigh executives’ compensation packages more heavily in favor of equity-based compensation versus salary, as they believe performance and equity-based compensation is important to maintain a strong link between executive incentives and the creation of shareholder value. The board and the Committee believe that performance and equity-based compensation are the most important component of the total executive compensation package for maximizing shareholder value while, at the same time, attracting, motivating and retaining high-quality executives. The board and the Committee have reviewed this Compensation Discussion and Analysis with the company’s management.
 
Benchmarking of Compensation Practices
 
The board and the Committee believe it is important when making compensation-related decisions to be informed as to current practices of similarly situated publicly held companies in the life sciences industry. Beginning in October 2007, the board and the Committee reviewed several publicly available broad-based studies conducted by an outside consulting firm that specializes in executive compensation in the biotechnology industry. One study reviewed the salary and cash bonus compensation practices of up to 575 publicly held companies in the life sciences industry. The companies in this survey were sorted based on similar employee count and on location to obtain more relevant data. The board and the Committee also referenced another study of equity compensation practices in the same survey group. The companies in this second survey were sorted based on similar capitalization to obtain more relevant data. In addition to benchmarking studies, the board and the Committee take into account input from other sources, including input from other independent members of the board of directors and publicly available data relating to the compensation practices and policies of other companies within and outside of our industry. For example, in 2006, the Committee reviewed a special study of the compensation practices of 19 publicly held life sciences companies that were chosen based on business characteristics similar to ours.
 
Benchmarking surveys were used primarily in making compensation decisions for Drs. Igor Gonda, our CEO, and Babatunde Otulana, our Chief Medical Officer. Given the company’s operating performance and continued need for capital, the board and the Committee used these surveys to establish total cash compensation for these two executive officers at a level substantially equivalent to the median cash compensation paid by the companies in the surveys. Consistent with the board’s and the Committee’s greater emphasis on performance and equity-based compensation, they sought to establish performance-based equity compensation for these two executive officers at a level generally greater than the equity-based compensation paid by 75% of the companies in the surveys.
 
While benchmarking may not always be appropriate as a stand-alone tool for setting compensation due to the aspects of our business and objectives that may be unique to us, the board and the Committee generally believe that gathering this information is an important part of their compensation-related decision-making process.

Table of Contents

Given that Mr. Norman Halleen, our Interim Chief Financial Officer, is engaged as a part-time consultant, the Committee did not feel the results from its benchmarking surveys were relevant to a determination of his compensation. The board and the Committee aim to establish Mr. Halleen’s compensation at a level comparable to fees charged by similar service providers.
 
The Committee has in the past retained and may in the future retain the services of third-party executive compensation specialists from time to time, as the Committee sees fit, in connection with the establishment of compensation and related policies.
 
Compensation Components
 
Base Salary.  Generally, the board and the Committee believe that executive base salaries should be set near the median of the range of salaries for executives in similar positions and with similar responsibilities at comparable companies. The board and the Committee believe that maintaining base salary amounts at or near the industry median minimizes competitive disadvantage while conserving the company’s cash resources and avoiding paying amounts in excess of what they believe to be necessary to motivate executives to meet corporate goals. Base salaries are typically reviewed annually. Management presents the Committee with its initial recommendations for executive salary levels and the Committee and board may adjust these base salary recommendations to realign such salaries with median market levels after taking into account individual responsibilities, performance, experience as well as the benchmarking data reviewed by the Committee.
 
For 2007, the board, upon recommendation of the Committee, established base salaries for Drs. Gonda and Otulana of $320,000 and $289,000, respectively. These salaries were unchanged from the executives’ 2006 base salaries. Given the company’s financial position, the board and the Committee did not feel an increase in base salary for 2007 was appropriate.
 
In December 2007, the board, upon recommendation of the Committee, established 2008 base salaries for Drs. Gonda and Otulana of $380,000 and $322,000, respectively, for an average salary increase for both executives of 15% over 2007 salaries. The board’s and the Committee’s primary motivation for raising salaries was establishing salaries near the median of the range of salaries for executives in similar positions and with similar responsibilities at comparable companies. The board and the Committee also recognized that the executives had foregone salary increases in 2007 and the larger than usual salary increase was partly a result of the lack of a salary increase in 2007, as well as being based on the Company’s and the executives individual performance.
 
Mr. Halleen is paid a flat fee of $22,500 per month, which the board and the Committee believe is comparable to fees charged by similar service providers. Mr. Halleen is not entitled to receive a bonus or other performance or equity-based compensation.
 
Annual Executive Bonus Plan.
 
In addition to base salaries, the board and the Committee believe that performance-based cash bonuses play an important role in providing incentives to our executives to achieve defined annual corporate goals. Prior to or near the beginning of each year, the board, upon the recommendation of the Committee, reviews the target bonus amount (defined as a set percentage of base salary) for each executive. The target bonus amount is set at a level that, upon achievement of 100% of the target goals, will result in bonus payments that the board and the Committee believe to be at or near the median level for target bonus amounts for comparable companies included in the benchmark studies and that, upon achievement beyond the target goals, can result in bonuses of up to 150% of the target bonus amount.
 
The Committee also reviews a detailed set of overall corporate performance goals (target goals) prepared by management that are intended to apply to the executives’ bonus awards and, with some distinctions, to the bonus awards for all of our other employees. The Committee then works with management to develop final corporate performance goals that are set at a level the Committee believes management can reasonably achieve over the next year. For each individual corporate goal, the Committee establishes relative weights and then sets target performance for Level 1 satisfaction (50% of target payout for that goal), Level 2 satisfaction (100% of target payout for that goal) and Level 3 satisfaction (150% of target payout for that goal) of the corporate goal, with the attainment of


29


Table of Contents

each specified level of performance tied to a specific percentage payout of the target bonus amount for that goal. The relative weights for each individual corporate goal may be changed by the board during the year as a result of external and internal events and their impact upon the company. For 2007, the board predetermined that failure to meet Level 2 performance for a corporate goal would result in no bonus payout to the executives with respect to that goal.
 
At the end of each year, the board, upon the recommendation of the Committee, determines the level of achievement for each corporate goal, on a goal by goal basis, and awards credit for the achievement of goals as a percentage of the target bonus. Final determinations as to bonus levels are then based on the achievement of these corporate goals, which are the same for all executives, as well as the board’s and the Committee’s assessment as to the overall success of our company and the development of our business.
 
Actual bonuses are targeted to be paid to the executives at the end of each fiscal year and may be above or below target bonus levels, at the discretion of the board. While the board and Committee retain full discretion as to the amount, if any, of bonus compensation paid to executives, the Committee strives to develop corporate goals that are objective and reliably measurable to deemphasize the need for subjective discretion. The board and Committee strive to limit their discretionary authority to unusual circumstances. For example, in 2006, though the executive team had satisfied corporate goals to a level that would have entitled them to a payout of 79% of their target bonus amounts, the Committee only awarded a partial bonus at the end of 2006 and only awarded the remaining portion of the bonus in February 2007 after the successful completion of the company’s follow-on public offering. The board and Committee felt that given the company’s cash position and the overall development of its business in 2006, successful completion of the follow-on public offering was an essential component of the executives’ performance for the year. As a result the remaining portion of the bonus awarded in February 2007 to Messrs. Otulana and Chesterman was $78,000 each and to Dr. Gonda was $50,000.
 
Bonus payments under our annual bonus plan are contingent on continued employment with the company at the end of the year.
 
In February 2007, the board, upon recommendation of the Committee, established 2007 target bonus awards (as a percentage of base salary) of 50% for Dr. Gonda and 40% for Dr. Otulana. In 2007, the Committee determined that half of the executives’ bonus awards would be earned based on the achievement of specified corporate performance goals, including meeting various milestones related to the development of the inhaled liposomal ciprofloxacin program, the number and stage of development of various products in the company’s product pipeline, meeting various milestones related to the development of the nicotine product and the amount of the Company’s cash burn for the 2007 fiscal year. The Committee determined the remaining half of the executives’ bonus awards would be earned based on our common stock achieving specified price targets.
 
Management develops corporate performance goals, which are reviewed by the Committee and recommended to the board for approval. The goals are designed to lead to results that will maximize shareholder value. In particular, at the start of 2007, the board and Committee concluded that the company’s stock price undervalued the company. In response, the Committee developed a corporate goal and appropriately weighted the goal to reward management for a significant increase in the company’s stock price. Similarly, the board and Committee determined that the ARD-3100 program will likely drive the company’s value in 2007 and 2008, and so they have weighted the goal related to development of the ARD-3100 program higher than the other operational performance goals.
 
In January 2008, the board and Committee determined that the above corporate performance goals that were achieved in 2007 merited a bonus award of 107.5% of the target cash bonus award for our executive officers, resulting in a cash bonus award of $172,000 for Dr. Gonda and $124,270 for Dr. Otulana.
 
In December 2007, the board, upon recommendation of the Committee, established 2008 target bonus awards (as a percentage of base salary) of 50% for Dr. Gonda and 40% for Dr. Otulana, which target bonus awards are unchanged from the prior year. 2008 bonus awards will again be capped at 150% of the target award, based on maximum goal achievement. For 2008, the board, upon recommendation of the Committee, determined that the executives’ bonus awards will be earned based on the achievement of specified milestones related to product and product-pipeline development milestones, activities related to contract manufacturers, and on the company’s effective cash management.

Actual bonus awards for 2008 will be determined at the end of the year and may be above or below the target bonus levels, at the discretion of the board and the Committee.
 
Mr. Halleen is not entitled to receive a bonus or other performance or equity-based compensation.
 
Equity Awards.  The board and the Committee believe that providing a significant portion of our executives’ total compensation package in stock options and other performance-based equity awards aligns the incentives of our executives with the interests of our shareholders and with our long-term success. The board and the Committee develop their equity award determinations based on their judgments as to whether the complete compensation packages provided to our executives, including prior equity awards, are sufficient to retain, motivate and adequately award the executives. As discussed above, the primary component of this judgment is based on information provided by benchmarking studies. The board and the Committee seek to establish performance-based equity compensation for these two executive officers at a level generally greater than the equity-based compensation paid by 75% of the companies in the surveys. Initial performance-based equity award grants are proposed to the Committee by management and the board and the Committee then work with management to ensure the award grants are at a level the board and the Committee feel are appropriate.
 
We grant equity awards through our 2005 Equity Incentive Plan, which was adopted by our board and shareholders to permit the grant of stock options, stock appreciation rights, restricted shares, restricted stock units, performance shares and other stock-based awards to our officers, directors, scientific advisory board members, employees and consultants. All of our employees, directors, scientific advisory board members and consultants are eligible to participate in the 2005 Equity Incentive Plan. The material terms of the 2005 Equity Incentive Plan are further described in note 6 to our financial statements included our Annual Report that is enclosed with these proxy materials. All options we grant have an exercise price equal to the fair market of our common stock on the date of grant.
 
In June 2007, the Committee granted Dr. Otulana an option to purchase up to 200,000 shares of our common stock. In December 2007, the Committee granted to Drs. Gonda and Otulana options to purchase up to 500,000 and 100,000 shares of our common stock, respectively. In addition, at the same time, the Committee granted to Drs. Gonda and Otulana performance-based restricted stock unit awards of up to 300,000 and 150,000 shares of our common stock, respectively, to be earned if within the three years following the grant of the award the company hits certain product and product-pipeline development milestones.
 
The Committee felt that the 2007 equity awards were necessary to bring our executives’ equity compensation levels at a level the Committee believes is necessary to retain a talented and capable management team. The restricted stock unit awards vest entirely on performance-based criteria and the Committee believes these grants are consistent with its approach of providing significant equity-based compensation to our executives in order to align our executives’ interests with those of our shareholders. The Committee anticipates making future refresh equity award grants to executives in December of each year, subject to its discretion. The Committee believes this award structure is consistent with our executive compensation policies.
 
Severance Benefits.  The board, upon recommendation of the Committee, previously adopted an Executive Officer Severance Plan, effective October 2005, and approved change of control agreements with each of our executive officers, the terms of which are more fully described below in the section entitled “Potential Payments Upon Termination or Change in Control.” The board and the Committee believe these severance and change in control benefits are an essential element of our executive compensation package and assist us in recruiting and retaining talented individuals. Our business is inherently risky and the board and the Committee believe the severance benefits encourage our executives to take necessary but reasonable business risks to increase shareholder value. The board and the Committee believe the change of control benefits align our executives’ interests more greatly in favor of corporate liquidity events that can be potentially valuable to our shareholders. They have established these severance and change of control benefits at levels that they feel are comparable to benefits offered to executives in similar positions and with similar responsibilities at comparable companies.
 
Other Compensation.  All of our executives are eligible to participate in our employee benefit plans, including medical, dental, life insurance and 401(k) plans. These plans are available to all salaried employees and do not discriminate in favor of executive officers. It is generally our policy to not extend significant perquisites


31


Table of Contents

to our executives that are not available to our employees generally. We have no current plans to make changes to levels of benefits and perquisites provided to executives.
 
The board revised our vacation policy in December 2007 to cap the amount of paid vacation days our executives are eligible to receive at a maximum of 30 days per year. The board also recently reduced the maximum number of paid vacation days that can be accrued at any time to a maximum of 30 days (previously, depending upon how long the executive was with the company, the cap was as high as 60 days). As a result of this change, Dr. Otulana was paid $33,346 to compensate him for the loss of vacation time he had accrued that was in excess of 30 days.

(1) The method of and assumptions used to calculate the value of stock awards and option awards granted to our named executive officers is discussed in Note 1 of the notes to our financial statements included in our Annual Report on Form 10-K.
 
(2) Each executive officer employed at the end of 2007 received a cash bonus for achievement of certain corporate and personal goals pursuant to our 2007 Executive Bonus Plan.
 
(3) Dr. Gonda commenced his employment with us on August 10, 2006. Dr. Gonda’s bonus reflects a $100,000 signing bonus for accepting his offer of employment. In 2006, Dr. Gonda also received a stock bonus award for up to 100,000 shares of our common stock. We valued Dr. Gonda’s stock bonus on a Monte-Carlo simulation due to the path-dependency of the award. We believe that the Monte-Carlo simulation provides a more precise estimate for the grant date fair value of a market-based equity award as the simulation allows for vesting throughout the vesting period. In accordance with Securities and Exchange Commission regulations, the cost reflected in the table above only includes the portion of the award’s value that was amortized for 2006 and 2007. Dr. Gonda’s compensation includes $21,000 in director fees and options expense of $2,485 that were both attributable to his services as a director prior to his appointment as our CEO in August 2006. Dr. Gonda has not received any additional compensation for his services as a director since he was appointed CEO in August 2006.
 
(4) Mr. Halleen was appointed as Interim CFO on July 2, 2007.

In 2008, the Chairman of the Board will receive an annual retainer of $50,000 and all other non-employee directors will receive an annual cash retainer of $30,000. Board members also receive additional annual retainers for serving on board committees. The additional annual retainer for the Chairman of the Audit Committee will be $15,000 and the additional annual retainer for all other members of the Audit Committee will be $5,000. The additional annual retainer for the Chairman of the Compensation Committee and the Chairman of the Nominating and Corporate Governance Committee will be $10,000 and the additional annual retainer for all other members will be $5,000. The board retainer covers six meetings in a year and, if exceeded, the Chairman of the Board will receive $1,500 for each additional meeting and the other board members will receive $1,000 for each additional meeting. If the number of meetings in a year for any given committee exceeds four, the chairman of the committee will receive $1,500 for each additional meeting and the other committee members will receive $1,000 for each additional meeting. Our directors are also entitled to receive reimbursement of reasonable out-of-pocket expenses incurred by them to attend board meetings.
 
In addition to the cash compensation, each non-employee director will be granted an annual stock option award. Each non-employee director will automatically receive an option to purchase up to 30,000 shares of our common stock upon election to the board. The Chairman of the Board will be granted automatically an option to purchase up to 35,000 shares of our common stock upon re-election to the board and the other members of the board will be granted automatically an option to purchase up to 20,000 shares of our common stock upon re-election to the board. Generally, these options vest quarterly in four equal installments in the year following issuance.
 
Limitation of Liability of Officers and Directors and Indemnification
 
Our articles of incorporation and bylaws include provisions to (i) eliminate the personal liability of our directors for monetary damages resulting from breaches of their fiduciary duty, to the extent permitted by California law and (ii) permit us to indemnify our directors and officers, employees and other agents to the fullest extent permitted by the California Corporations Code. Pursuant to Section 317 of the California Corporations Code, a corporation generally has the power to indemnify its present and former directors, officers, employees and agents against any expenses incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of a corporation and, with respect to any criminal action, they had no reasonable cause to believe their conduct was unlawful. We believe that these provisions are necessary to attract and retain qualified persons as directors and officers. These provisions do not eliminate liability for breach of the directors’ duty of loyalty to us or our shareholders, for acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, for any transaction from which the director derived an improper personal benefit or for any willful or negligent payment of any unlawful dividend.
 
We entered into indemnification agreements with certain officers, including each of our named executive officers, and each of our directors that provide, among other things, that we will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements such officer or director may be required to pay in actions or proceedings to which such officer or director is or may be made a party by reason of such officer’s or director’s position as an officer, director or other agent of us, and otherwise to the full extent permitted under California law and our bylaws.

CERTAIN TRANSACTIONS
 
Review, Approval or Ratification of Transactions with Related Persons
 
Our policy is to require that any transaction with a related party required to be reported under applicable SEC rules, other than compensation-related matters and waivers of our code of business conduct and ethics, be reviewed and approved or ratified by a majority of independent, disinterested directors. We have not adopted procedures for review of, or standards for approval of, these transactions, but instead review such transactions on a case by case basis. Our policy is to require that all compensation-related matters be recommended for board approval by the Compensation Committee and that any waiver of our code of business conduct and ethics be reviewed and approved by the Nominating and Corporate Governance Committee and be reported under applicable SEC rules.
 
HOUSEHOLDING OF PROXY MATERIALS
 
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding, “ potentially means extra convenience for shareholders and cost savings for companies.
 
This year, a number of brokers with account holders who are our shareholders will be “householding” our proxy materials. A single proxy statement will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding “ will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, please notify your broker, direct your written request to Aradigm Corporation, Corporate Secretary, 3929 Point Eden Way, Hayward, CA 94545 or contact our Corporate Secretary at (510) 265-9000. Shareholders who currently receive multiple copies of the proxy statement at their address and would like to request “householding “ of their communications should contact their broker.
 
OTHER MATTERS
 
The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

(d) Consultants.  A Consultant shall not be eligible for the grant of a Stock Award if, at the time of grant, a Form S-8 Registration Statement under the Securities Act (“Form S-8”) is not available to register either the offer or the sale of the Company’s securities to such Consultant because of the nature of the services that the Consultant is providing to the Company, because the Consultant is not a natural person, or because of any other rule governing the use of Form S-8.
 
6.   Option Provisions.
 
Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type of Option. The provisions of separate Options need not be identical; provided, however, that each Option Agreement shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:
 
(a) Term.  The Board shall determine the term of an Option; provided, however, that subject to the provisions of Section 5(b) regarding Ten Percent Shareholders, no Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date of grant.
 
(b) Exercise Price of an Incentive Stock Option.  Subject to the provisions of Section 5(b) regarding Ten Percent Shareholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner consistent with the provisions of Section 424(a) of the Code.
 
(c) Exercise Price of a Nonstatutory Stock Option.  The exercise price of each Nonstatutory Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner consistent with the provisions of Section 424(a) of the Code.
 
(d) Consideration.  The purchase price of Common Stock acquired pursuant to the exercise of an Option shall be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The methods of payment permitted by this Section 6(d) are:
 
(i) by cash or check;


A-9


Table of Contents

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds;
 
(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock;
 
(iv) according to a deferred payment or similar arrangement with the Optionholder; provided, however, that interest shall compound at least annually and shall be charged at the minimum rate of interest necessary to avoid (i) the imputation of interest income to the Company and compensation income to the Optionholder under any applicable provisions of the Code and (ii) the treatment of the Option as a variable award for financial accounting purposes; or
 
(v) in any other form of legal consideration that may be acceptable to the Board.
 
(e) Transferability of Options.  The Board may, in its sole discretion, impose such limitations on the transferability of Options as the Board shall determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options shall apply:
 
(i) Restrictions on Transfer.  An Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder.
 
(ii) Domestic Relations Orders. Notwithstanding the foregoing, an Option may be transferred pursuant to a domestic relations order.
 
(iii) Beneficiary Designation. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.
 
(f) Vesting Generally.  The total number of shares of Common Stock subject to an Option may vest and therefore become exercisable in periodic installments that may or may not be equal. The Option may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this Section 6(f) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised.
 
(g) Termination of Continuous Service.  In the event that an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.
 
(h) Extension of Termination Date.  An Optionholder’s Option Agreement may provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability or upon a Change in Control) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such registration requirements or (ii) the expiration of the term of the Option as set forth in the Option Agreement.

(i) Disability of Optionholder.  In the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination of Continuous Service, the Optionholder does not exercise his or her Option within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.
 
(j) Death of Optionholder.  In the event that (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionholder’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of such Option as set forth in the Option Agreement. If, after the Optionholder’s death, the Option is not exercised within the time specified herein or in the Option Agreement (as applicable), the Option shall terminate.
 
(k) Early Exercise.  The Option may include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. The Company shall not be required to exercise its repurchase option until at least six (6) months (or such longer or shorter period of time necessary to avoid a charge to earnings for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option.
 
7.   Provisions of Stock Awards other than Options.
 
(a) Stock Purchase Awards.  Each Stock Purchase Award Agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. At the Board’s election, shares of Common Stock may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Stock Purchase Award lapse or (ii) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Board. The terms and conditions of Stock Purchase Award Agreements may change from time to time, and the terms and conditions of separate Stock Purchase Award Agreements need not be identical, provided, however, that each Stock Purchase Award Agreement shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:
 
(i) Purchase Price.  At the time of the grant of a Stock Purchase Award, the Board will determine the price to be paid by the Participant for each share subject to the Stock Purchase Award.

8.   Covenants of the Company.
 
(a) Availability of Shares.  During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Stock Awards.
 
(b) Securities Law Compliance.  The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained.

(e) Investment Assurances.  The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (ii) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.
 
(f) Withholding Obligations.  To the extent provided by the terms of a Stock Award Agreement, the Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award; or (iii) by such other method as may be set forth in the Stock Award Agreement.

The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained shall be conclusively determined by the Board in its sole discretion. The maximum benefit to be received by any individual in any calendar year attributable to Stock Awards described in this Section 10(h) shall not exceed the value of one hundred thousand (100,000) shares of Common Stock.
 
11.   Adjustments upon Changes in Common Stock; Corporate Transactions.
 
(a) Capitalization Adjustments.  If any change is made in, or other events occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the effective date of the Plan set forth in Section 14 without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company (each a “Capitalization Adjustment”)), the Plan shall be appropriately adjusted in: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Sections 4(a) and 4(b), (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 4(b), (iii) the maximum number of securities that may be awarded to any person pursuant to Sections 5(c) and 10(h) and (iv) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a transaction “without receipt of consideration” by the Company.)
 
(b) Dissolution or Liquidation.  In the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to the Company’s right of repurchase) shall terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase option may be repurchased by


A-15


Table of Contents

the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.
 
(c) Corporate Transaction.  The following provisions shall apply to Stock Awards in the event of a Corporate Transaction unless otherwise provided in a written agreement between the Company or any Affiliate and the holder of the Stock Award:
 
(i) Stock Awards May Be Assumed.  In the event of a Corporate Transaction, any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock awards for Stock Awards outstanding under the Plan (including but not limited to, awards to acquire the same consideration paid to the shareholders of the Company pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or the successor’s parent company, if any), in connection with such Corporate Transaction. A surviving corporation or acquiring corporation may choose to assume or continue only a portion of a Stock Award or substitute a similar stock award for only a portion of a Stock Award. The terms of any assumption, continuation or substitution shall be set by the Board in accordance with the provisions of Section 3.
 
(ii) Stock Awards Held by Current Participants.  In the event of a Corporate Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock Awards, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the Corporate Transaction (referred to as the “Current Participants”), the vesting of such Stock Awards (and, if applicable, the time at which such Stock Awards may be exercised) shall (contingent upon the effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), and such Stock Awards shall terminate if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction, and any reacquisition or repurchase rights held by the Company with respect to such Stock Awards shall lapse (contingent upon the effectiveness of the Corporate Transaction).
 
(iii) Stock Awards Held by Persons other than Current Participants.  In the event of a Corporate Transaction in which the surviving corporation or acquiring corporation (or its parent company) does not assume or continue such outstanding Stock Awards or substitute similar stock awards for such outstanding Stock Awards, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by persons other than Current Participants, the vesting of such Stock Awards (and, if applicable, the time at which such Stock Award may be exercised) shall not be accelerated and such Stock Awards (other than a Stock Award consisting of vested and outstanding shares of Common Stock not subject to the Company’s right of repurchase) shall terminate if not exercised (if applicable) prior to the effective time of the Corporate Transaction; provided, however, that any reacquisition or repurchase rights held by the Company with respect to such Stock Awards shall not terminate and may continue to be exercised notwithstanding the Corporate Transaction.
 
(iv) Payment for Stock Awards in Lieu of Exercise.  Notwithstanding the foregoing, in the event a Stock Award will terminate if not exercised prior to the effective time of a Corporate Transaction, the Board may provide, in its sole discretion, that the holder of such Stock Award may not exercise such Stock Award but will receive a payment, in such form as may be determined by the Board, equal in value to the excess, if any, of (A) the value of the property the holder of the Stock Award would have received upon the exercise of the Stock Award, over (B) any exercise price payable by such holder in connection with such exercise.
 
(d) Change in Control.  A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as may be provided in the Stock Award Agreement for such Stock Award or


A-16


Table of Contents

as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration shall occur.

Amended by the Board of Directors on April 4, 2008
 
1.   Purpose
 
(a) The purpose of the Employee Stock Purchase Plan (the “Plan”) is to provide a means by which employees of Aradigm Corporation, a California corporation (the “Company”), and its Affiliates, as defined in subparagraph 1(b), which are designated as provided in subparagraph 2(b), may be given an opportunity to purchase stock of the Company.
 
(b) The word “Affiliate” as used in the Plan means any parent corporation or subsidiary corporation of the Company, as those terms are defined in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended (the “Code”).
 
(c) The Company, by means of the Plan, seeks to retain the services of its employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for the success of the Company.
 
(d) The Company intends that the rights to purchase stock of the Company granted under the Plan be considered options issued under an “employee stock purchase plan” as that term is defined in Section 423(b) of the Code.
 
2.   Administration
 
(a) The Plan shall be administered by the Board of Directors (the “Board”) of the Company unless and until the Board delegates administration to a Committee, as provided in subparagraph 2(c). Whether or not the Board has delegated administration, the Board shall have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan.
 
(b) The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan:
 
(i) To determine when and how rights to purchase stock of the Company shall be granted and the provisions of each offering of such rights (which need not be identical).


B-1


Table of Contents

(ii) To designate from time to time which Affiliates of the Company shall be eligible to participate in the Plan.
 
(iii) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.
 
(iv) To amend the Plan as provided in paragraph 13.
 
(v) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and its Affiliates and to carry out the intent that the Plan be treated as an “employee stock purchase plan” within the meaning of Section 423 of the Code.
 
(c) The Board may delegate administration of the Plan to a Committee composed of not fewer than two (2) members of the Board (the “Committee”) constituted in accordance with the requirements of Rule 16b-3 under the Exchange Act. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan.
 
3.   Shares Subject to the Plan
 
(a) Subject to the provisions of paragraph 12 relating to adjustments upon changes in stock, the stock that may be sold pursuant to rights granted under the Plan shall not exceed in the aggregate two million fifty thousand (2,050,000) shares of the Company’s common stock (the “Common Stock”). If any right granted under the Plan shall for any reason terminate without having been exercised, the Common Stock not purchased under such right shall again become available for the Plan.
 
(b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise.
 
4.   Grant of Rights; Offering
 
The Board or the Committee may from time to time grant or provide for the grant of rights to purchase Common Stock of the Company under the Plan to eligible employees (an “Offering”) on a date or dates (the “Offering Date(s)”) selected by the Board or the Committee. Each Offering shall be in such form and shall contain such terms and conditions as the Board or the Committee shall deem appropriate, which shall comply with the requirements of Section 423(b)(5) of the Code that all employees granted rights to purchase stock under the Plan shall have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering shall include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering shall be effective, which period shall not exceed twenty-seven (27) months beginning with the Offering Date, and the substance of the provisions contained in paragraphs 5 through 8, inclusive.
 
5.   Eligibility
 
(a) Rights may be granted only to employees of the Company or, as the Board or the Committee may designate as provided in subparagraph 2(b), to employees of any Affiliate of the Company. Except as provided in subparagraph 5(b), an employee of the Company or any Affiliate shall not be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee has been in the employ of the Company or any Affiliate for such continuous period preceding such grant as the Board or the Committee may require, but in no event shall the required period of continuous employment be equal to or greater than two (2) years. In addition, unless otherwise determined by the Board or the Committee and set forth in the terms of the applicable Offering, no employee of the Company or any Affiliate shall be eligible to be granted rights under the Plan, unless, on the Offering Date, such


B-2


Table of Contents

employee’s customary employment with the Company or such Affiliate is for at least twenty (20) hours per week and at least five (5) months per calendar year.
 
(b) The Board or the Committee may provide that, each person who, during the course of an Offering, first becomes an eligible employee of the Company or designated Affiliate will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an eligible employee or occurs thereafter, receive a right under that Offering, which right shall thereafter be deemed to be a part of that Offering. Such right shall have the same characteristics as any rights originally granted under that Offering, as described herein, except that:
 
(i) the date on which such right is granted shall be the “Offering Date” of such right for all purposes, including determination of the exercise price of such right;
 
(ii) the period of the Offering with respect to such right shall begin on its Offering Date and end coincident with the end of such Offering; and
 
(iii) the Board or the Committee may provide that if such person first becomes an eligible employee within a specified period of time before the end of the Offering, he or she will not receive any right under that Offering.
 
(c) No employee shall be eligible for the grant of any rights under the Plan if, immediately after any such rights are granted, such employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any employee, and stock which such employee may purchase under all outstanding rights and options shall be treated as stock owned by such employee.
 
(d) An eligible employee may be granted rights under the Plan only if such rights, together with any other rights granted under “employee stock purchase plans” of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such employee’s rights to purchase stock of the Company or any Affiliate to accrue at a rate which exceeds twenty five thousand dollars ($25,000) of fair market value of such stock (determined at the time such rights are granted) for each calendar year in which such rights are outstanding at any time.
 
(e) Officers of the Company and any designated Affiliate shall be eligible to participate in Offerings under the Plan, provided, however, that the Board may provide in an Offering that certain employees who are highly compensated employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to participate.
 
6.   Rights; Purchase Price
 
(a) On each Offering Date, each eligible employee, pursuant to an Offering made under the Plan, shall be granted the right to purchase up to the number of shares of Common Stock of the Company purchasable with a percentage designated by the Board or the Committee not exceeding fifteen percent (15%) of such employee’s Earnings (as defined by the Board or the Committee in each Offering) during the period which begins on the Offering Date (or such later date as the Board or the Committee determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering. The Board or the Committee shall establish one or more dates during an Offering (the “Purchase Date(s)”) on which rights granted under the Plan shall be exercised and purchases of Common Stock carried out in accordance with such Offering.
 
(b) In connection with each Offering made under the Plan, the Board or the Committee may specify a maximum number of shares that may be purchased by any employee as well as a maximum aggregate number of shares that may be purchased by all eligible employees pursuant to such Offering. In addition, in connection with each Offering that contains more than one Purchase Date, the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given Purchase Date under the Offering. If the aggregate purchase of shares upon exercise of rights granted under the Offering would exceed any such maximum aggregate number, the Board or the Committee shall make a pro rata allocation of the shares available in as nearly a uniform manner as shall be practicable and as it shall deem to be equitable.


B-3


Table of Contents

(c) The purchase price of stock acquired pursuant to rights granted under the Plan shall be not less than the lesser of:
 
(i) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Offering Date; or
 
(ii) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Purchase Date.
 
7.   Participation; Withdrawal; Termination
 
(a) An eligible employee may become a participant in the Plan pursuant to an Offering by delivering a participation agreement to the Company within the time specified in the Offering, in such form as the Company provides. Each such agreement shall authorize payroll deductions of up to the maximum percentage specified by the Board or the Committee of such employee’s Earnings during the Offering (as defined by the Board or Committee in each Offering). The payroll deductions made for each participant shall be credited to an account for such participant under the Plan and shall be deposited with the general funds of the Company. A participant may reduce (including to zero) or increase such payroll deductions, and an eligible employee may begin such payroll deductions, after the beginning of any Offering only as provided for in the Offering. A participant may make additional payments into his or her account only if specifically provided for in the Offering and only if the participant has not had the maximum amount withheld during the Offering.
 
(b) At any time during an Offering, a participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company provides. Such withdrawal may be elected at any time prior to the end of the Offering except as provided by the Board or the Committee in the Offering. Upon such withdrawal from the Offering by a participant, the Company shall distribute to such participant all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the participant) under the Offering, without interest, and such participant’s interest in that Offering shall be automatically terminated. A participant’s withdrawal from an Offering will have no effect upon such participant’s eligibility to participate in any other Offerings under the Plan but such participant will be required to deliver a new participation agreement in order to participate in subsequent Offerings under the Plan.
 
(c) Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of any participating employee’s employment with the Company and any designated Affiliate, for any reason, and the Company shall distribute to such terminated employee all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the terminated employee) under the Offering, without interest.
 
(d) Rights granted under the Plan shall not be transferable by a participant otherwise than by will or the laws of descent and distribution, or by a beneficiary designation as provided in paragraph 14 and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such rights are granted.
 
8.   Exercise
 
(a) On each Purchase Date specified therefor in the relevant Offering, each participant’s accumulated payroll deductions and other additional payments specifically provided for in the Offering (without any increase for interest) will be applied to the purchase of whole shares of stock of the Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares shall be issued upon the exercise of rights granted under the Plan. The amount, if any, of accumulated payroll deductions remaining in each participant’s account after the purchase of shares which is less than the amount required to purchase one share of stock on the final Purchase Date of an Offering shall be held in each such participant’s account for the purchase of shares under the next Offering under the Plan, unless such participant withdraws from such next Offering, as provided in subparagraph 7(b), or is no longer eligible to be granted rights under the Plan, as provided in paragraph 5, in which case such amount shall be distributed to the participant after such final Purchase Date, without interest. The amount, if any, of accumulated payroll deductions


B-4


Table of Contents

remaining in any participant’s account after the purchase of shares which is equal to the amount required to purchase whole shares of stock on the final Purchase Date of an Offering shall be distributed in full to the participant after such Purchase Date, without interest.
 
(b) No rights granted under the Plan may be exercised to any extent unless the shares to be issued upon such exercise under the Plan (including rights granted thereunder) are covered by an effective registration statement pursuant to the Securities Act of 1933, as amended (the “Securities Act”) and the Plan is in material compliance with all applicable state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not so registered or in such compliance, no rights granted under the Plan or any Offering shall be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve (12) months and the Purchase Date shall in no event be more than twenty-seven (27) months from the Offering Date. If on the Purchase Date of any Offering hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, no rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering (reduced to the extent, if any, such deductions have been used to acquire stock) shall be distributed to the participants, without interest.
 
9.   Covenants of the Company
 
(a) During the terms of the rights granted under the Plan, the Company shall keep available at all times the number of shares of stock required to satisfy such rights.
 
(b) The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the rights granted under the Plan. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such rights unless and until such authority is obtained.
 
10.   Use of Proceeds from Stock
 
Proceeds from the sale of stock pursuant to rights granted under the Plan shall constitute general funds of the Company.
 
11.   Rights as a Shareholder
 
A participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to rights granted under the Plan unless and until the participant’s shareholdings acquired upon exercise of rights under the Plan are recorded in the books of the Company.
 
12.   Adjustments upon Changes in Stock
 
(a) If any change is made in the stock subject to the Plan, or subject to any rights granted under the Plan (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan and outstanding rights will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan and the class(es) and number of shares and price per share of stock subject to outstanding rights. Such adjustments shall be made by the Board or the Committee, the determination of which shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a “transaction not involving the receipt of consideration by the Company.”)
 
(b) In the event of: (1) a dissolution or liquidation of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the shares of the Company’s Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) the acquisition by


B-5


Table of Contents

any person, entity or group within the meaning of Section 13(d) or 14(d) of the Exchange Act or any comparable successor provisions (excluding any employee benefit plan, or related trust, sponsored or maintained by the Company or any Affiliate of the Company) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable successor rule) of securities of the Company representing at least fifty percent (50%) of the combined voting power entitled to vote in the election of directors, then, as determined by the Board in its sole discretion (i) any surviving or acquiring corporation may assume outstanding rights or substitute similar rights for those under the Plan, (ii) such rights may continue in full force and effect, or (iii) participants’ accumulated payroll deductions may be used to purchase Common Stock immediately prior to the transaction described above and the participants’ rights under the ongoing Offering terminated.
 
13.   Amendment of the Plan
 
(a) The Board at any time, and from time to time, may amend the Plan. However, except as provided in paragraph 12 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the shareholders of the Company within twelve (12) months before or after the adoption of the amendment, where the amendment will:
 
(i) Increase the number of shares reserved for rights under the Plan;
 
(ii) Modify the provisions as to eligibility for participation in the Plan (to the extent such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3 promulgated under the Exchange Act as amended (“Rule 16b-3”)); or employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3 promulgated under the Exchange Act as amended (“Rule 16b-3”)); or
 
(iii) Modify the Plan in any other way if such modification requires shareholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3.
 
It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to employee stock purchase plans and/or to bring the Plan and/or rights granted under it into compliance therewith.
 
(b) Rights and obligations under any rights granted before amendment of the Plan shall not be impaired by any amendment of the Plan, except with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulations, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code.
 
14.   Designation of Beneficiary
 
(a) A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant’s account under the Plan in the event of such participant’s death subsequent to the end of an Offering but prior to delivery to the participant of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death during an Offering.
 
(b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

15.   Termination or Suspension of the Plan
 
(a) The Board in its discretion, may suspend or terminate the Plan at any time. No rights may be granted under the Plan while the Plan is suspended or after it is terminated.
 
(b) Rights and obligations under any rights granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except as expressly provided in the Plan or with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulation, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code.
