leading producer and marketer of low-carbon renewable fuels in the Western United States, in part by expanding production at our
Madera, California facility to its full production capacity,  expanding
our relationships with customers and third-party ethanol producers to market higher volumes of ethanol and by expanding the market
for ethanol by continuing to work with state governments to encourage the adoption of policies and standards that promote ethanol
as a fuel additive and transportation fuel. Further, we may seek to provide management services for other third-party ethanol production
facilities in the Western United States.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">Investing in our common stock involves significant
risks. Before making an investment decision, you should consider carefully the risks, uncertainties and other factors described
in our most recent Annual Report on Form 10-K, as supplemented and updated by subsequent quarterly reports on Form&nbsp; 10-Q and
current reports on Form 8-K that we have filed or will file with the Securities and Exchange Commission and in documents which
are incorporated by reference into this prospectus, as well as the risk factors and other information contained in or incorporated

financial condition or results of operations could be materially harmed. In that case, the trading price of our common stock could

we describe are not the only ones we face. Additional risks not presently known to us, or that we currently deem immaterial, may
also impair our business operations. If any of the outcomes set forth in our risk factors were to occur, our business, financial
condition, or results of operations would likely suffer. In that event, the trading price of our common stock could decline, and
you could lose all or part of your investment.</P>

Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or Exchange Act. Our forward-looking statements
include our current expectations and projections about future results, performance, prospects and opportunities. We have tried
to identify these forward-looking statements by using words like &ldquo;believe,&rdquo; &ldquo;expect,&rdquo; &ldquo;may,&rdquo;
&ldquo;will,&rdquo; &ldquo;could,&rdquo; &ldquo;seek,&rdquo; &ldquo;estimate,&rdquo; &ldquo;continue,&rdquo; &ldquo;anticipate,&rdquo;

their use in the negative. You should not place undue reliance on these forward-looking statements, which speak only as to our
expectations, as of the date of this prospectus. These forward-looking statements are subject to a number of risks, uncertainties
and other factors that could cause our actual results, performance, prospects or opportunities to differ materially from those
expressed in, or implied by, these forward-looking statements.</P>

in or incorporated by reference into this prospectus and any applicable prospectus supplement. Given these risks and uncertainties,
readers are cautioned not to place undue reliance on our forward-looking statements. Projections included in such risk factors
have been prepared based on assumptions, which we believe to be reasonable, but not in accordance with United States generally
accepted accounting principles or any guidelines of the Securities and Exchange Commission. Actual results will vary, perhaps materially,
and we undertake no obligation to update the projections at any future date. You are strongly cautioned not to place undue reliance
on such projections. All subsequent written and oral forward-looking statements attributable to Pacific Ethanol or to persons acting
on our behalf are expressly qualified in their entirety by these cautionary statements. Except as required by federal securities
laws, we do not intend to update or revise any forward-looking statements, whether as a result of new information, future events

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">A number of provisions of Delaware law,
our certificate of incorporation and our bylaws contain provisions that could have the effect of delaying, deferring and discouraging
another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage coercive takeover
practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us
to first negotiate with our Board. We believe that the benefits of increased protection of our potential ability to negotiate with
an unfriendly or unsolicited acquiror outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of
these proposals could result in an improvement of their terms.</P>

success of any attempt to acquire us. These and other provisions may have the effect of deferring hostile takeovers or delaying
changes in control or management of Pacific Ethanol.</P>

a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An interested
stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of
interested stockholder status, did own 15% or more of a corporation&rsquo;s outstanding voting securities. We expect the existence
of its provision to have an anti-takeover effect with respect to transactions our Board does not approve in advance. We also anticipate
that Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock
held by stockholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The provisions of Delaware law, our certificate
of incorporation and our bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence,
they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile
takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these
provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.</P>
