Forward-Looking Statements
This communication contains forward-looking statements within the meaning of the federal securities laws. These forward-looking statements include, but are not
limited to, statements regarding Westlake Chemical Corporation’s (“Westlake”) proposal to acquire Axiall
Corporation (“Axiall”) (including financing of the
proposed transaction and the benefits, results, effects and timing of a transaction), all statements regarding Westlake’s (and Westlake’s and Axiall’s
combined)
expected future financial position, results of operations, cash flows, dividends, financing plans, business strategy, budgets, capital expenditures, competitive
positions, growth opportunities, plans and objectives of management, estimated synergies from the proposed transaction and statements containing the use of
forward-looking words, such as “may,” “will,” “could,” “would,” “should,” “project,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “potential,” “plan,”
“forecast,” “approximate,” “intend,” “upside,” and the like, or the use of future tense. Statements contained herein concerning the business outlook or future
economic performance, anticipated profitability, revenues, expenses, dividends or other financial items, and product or services
line growth of Westlake (and the
combined businesses of Westlake and Axiall), together with other statements that are not historical facts, are forward-looking statements that are estimates
reflecting the best judgment of Westlake based upon currently available information.  Statements concerning current conditions may also be forward-looking if
they imply a continuation of current conditions.
Such forward-looking statements are inherently uncertain, and stockholders and other potential investors must recognize that actual results may differ materially
from Westlake’s expectations as a result of a variety of factors, including, without limitation, those discussed below. Such forward-looking statements are based
upon management’s current expectations and include known and unknown risks, uncertainties and other factors, many of which Westlake is unable to predict or
control, that may cause Westlake’s actual results, performance or plans with respect to Axiall
to differ materially from any future results, performance or plans
expressed or implied by such forward-looking statements. These statements involve risks, uncertainties and other factors discussed below and detailed from time
to time in Westlake’s filings with the Securities and Exchange Commission (the “SEC”).
Risks and uncertainties related to the proposed business combination transaction include, but are not limited to:  (i) the ultimate outcome of any possible
transaction between Westlake and Axiall, including the possibility that Axiall
will not accept a transaction with Westlake, (ii) the ultimate outcome and results of
integrating the operations of Westlake and Axiall
if a transaction is consummated, (iii) the ability to obtain regulatory approvals and meet other closing conditions
to any possible transaction, including any necessary stockholder approvals, (iv) potential adverse reactions or changes to business relationships resulting from
the announcement, pendency or completion of the proposed transaction,  (v) competitive responses to the announcement or completion of the proposed
transaction, costs and difficulties related to the integration of Axiall’s
businesses and operations with Westlake’s businesses and operations, (vi) the inability to
obtain, or delays in obtaining, cost savings and synergies from the proposed transaction, (vii) uncertainties as to whether the completion of the proposed
transaction or any transaction will have the accretive effect on Westlake’s earnings or cash flows that it expects, (viii) unexpected costs, liabilities, charges or
expenses resulting from the proposed transaction, (ix) litigation relating to the proposed transaction, (x) the inability to retain key personnel, and (xi) any changes
in general economic and/or industry-specific conditions.
In addition to the factors set forth above, other factors that may affect Westlake’s plans, results or stock price are set forth
in Westlake’s Annual Report on Form
10-K and in its reports on Forms 10-Q and 8-K.  
Many of these factors are beyond Westlake’s control. Westlake cautions investors that any forward-looking statements made by Westlake are not guarantees of
future performance.  We do not intend, and undertake no obligation, to publish revised forward-looking statements to reflect events or circumstances after the
date of this communication or to reflect the occurrence of unanticipated events.

(a)
for the whole Axiall
group, including Building
Products
Maintain opportunity to capture cycle recovery through a
stronger company with a clear value creation strategy
Bet on volatile commodity prices
Long-term integration strategy captures value

Experienced management with strong track record of
value creation and history
of delivering on commitments
(a)
Revised Proposal of $23.35 per share reflects $14 per share in cash and 0.1967 in Westlake common stock based on the closing price of Westlake stock on April 1, 2016 (the last trading date before Westlake’s
revised proposal was made public).  Implied premium is based off the unaffected closing price of Axiall stock on January 22, 2016 (the last trading date before Westlake’s initial proposal was made)

(a)
Initial Proposal of $20 per share reflects $11 per share in cash and 0.1967 in Westlake common stock based on the closing price of Westlake stock on January 22, 2016.  Implied premium is based off the
unaffected closing price of Axiall stock on January 22, 2016 (the last trading date before Westlake’s initial proposal was made)
(b)
Revised Proposal of $23.35 per share reflects $14 per share in cash and 0.1967 in Westlake common stock based on the closing price of Westlake stock on April 1, 2016 (the last trading date before Westlake’s

destruction
associated

Products
sale


No Alternative Other Than to Go Directly to Shareholders
8
Westlake continues to believe that its proposal is in the best interests of Axiall
shareholders
The Revised Proposal represents significantly greater value and certainty than
Westlake believes can be achieved by Axiall’s
standalone strategy
Cash component provides certainty at a premium to unaffected stock price and stock
component allows for upside value creation in a larger and more diverse company
However, the Axiall
Board refuses to provide feedback or negotiate with Westlake
regarding its Revised Proposal
As a result, Westlake is moving forward with the nomination of nine independent,
experienced and highly-qualified directors
Westlake urges all Axiall
shareholders to elect new directors at Axiall’s
Annual
Meeting by voting for the GOLD card

Westlake's History of Superior Profit Growth Driven by
Efficient Capital Deployment

Westlake has a proven history that maximizes
returns and builds shareholder value
High-return strategy prioritizing brownfield /
de-bottlenecking initiatives
Axiall’s
strategy has been value destructive
Underinvestment in operations has resulted
in outages and earnings underperformance
Past acquisitions have destroyed
shareholder value (2006 Royal Building
Products
(a)

Pursuing current Building Products sale
process while spurning Westlake's superior

Axiall: Failure to Create Shareholder Value


Axiall Management Has Repeatedly
Failed to Deliver on Expectations
20
At various points over last 4 years, Axiall announced
that ECU margins have reached a “trough” or a “floor” level
Jul 19,
2012
(a)`
“… we illustrate the dramatic improvement in mid-cycle and
trough EBITDA
that comes from this combination. We expect
combined mid-cycle EBITDA of over $850 million, including cost
synergies […] Likewise, trough EBITDA for the combined company
will exceed $550 million”
Dec

2013
(b)
2013-2016 Growth 2-3% per year
plus exports will balance market”
May 6,
2014
(c)
“And I would say, at this level, there's a bit of pain to go much lower
than where we were or have been. So, that's another reason for
saying that we expected, as a general comment, that
we were at
the floor of ECUs at this point in time.”
Nov 3,
2015
(d)
“We also want to be respectful of the balance sheet and the right
level of leverage given the trough conditions that we're at right
now.”
Feb 11,
2016
(e)
“Axiall
expects to have significant operating leverage as the chlor-
alkali industry comes out of the trough
“Industry capacity rationalization underway; historically, caustic
prices start to recover within approximately 6-12 months
