Selling Security Holder Table
-----------------------------

         The "Selling Security Holder" table contained in the final prospectus
dated December 5, 2005 is updated as follows (1) to correct mistakes made in the
original prospectus as to the number of shares of common stock beneficially
owned and offered for resale by Alex Jachno and Agafia Jachno, on the one hand,
and Alex Jachno and Lisa Jachno, on the other hand, and (2) to reflect a
transfer of warrants to purchase 12,500 shares of common stock of Pacific
Ethanol, Inc. from Laird Q. Cagan to Fairmont Analytics, Inc., which warrants
were initially to be transferred to Fairmont Analytics, Inc. from Cagan-McAfee
Capital Partners, LLC instead of to Laird Q. Cagan, as more particularly
described in footnotes (c), (h) and (l) set forth below. Percentage of
beneficial ownership is based on 28,773,191 shares of common stock outstanding
as of December 23, 2005.

(a)    The shares of common stock and the warrants exchanged by the selling
       security holder in connection with the Share Exchange Transaction for the
       shares of common stock offered hereunder, including shares of common
       stock that underlie warrants, were initially acquired from PEI California
       in a private placement transaction in March 2005 under which PEI
       California raised an aggregate of $21.0 million at $3.00 per share and
       issued 7.0 million shares of common stock and warrants to purchase an
       aggregate of 700,000 and 1.4 million shares of common stock at an
       exercise price of $5.00 and $3.00 per share, respectively. PEI California
       also issued placement agent warrants to acquire up to an aggregate of
       678,000 shares of common stock at an exercise price of $3.00 per share.
       In aggregate, 9,778,000 shares of common stock resulting from this
       private placement transaction are being offered hereunder for resale.
(b)    The shares of common stock and the warrants exchanged by the selling
       security holder in connection with the Share Exchange Transaction for the
       shares of common stock offered hereunder were initially acquired from PEI
       California in a private placement transaction in February 2004 under
       which PEI California raised an aggregate of approximately $1.1 million at
       $1.50 per share and issued 752,201 shares of common stock. PEI California
       also issued placement agent warrants to acquire up to an aggregate of
       43,487 shares of common stock at an exercise price of $1.50 per share. In
       aggregate, 795,688 shares of common stock resulting from this private
       placement transaction are being offered hereunder for resale.
(c)    The shares of common stock and the warrants exchanged by the selling
       security holder in connection with the Share Exchange Transaction for the
       shares of common stock offered hereunder were initially acquired from PEI
       California in a private placement transaction in May 2004 under which PEI
       California raised an aggregate of $1.0 million at $2.00 per share and
       issued 500,000 shares of common stock. PEI California also issued
       placement agent warrants to acquire up to an aggregate of 50,000 shares
       of common stock at an exercise price of $2.00 per share. In aggregate,



       550,000 shares of common stock resulting from this private placement
       transaction are being offered hereunder for resale.
(h)    Of the shares of common stock offered by the selling security holder
       hereunder, 198,740 shares underlie warrants transferred to the holder by
       Chadbourn Securities, Inc. that were initially acquired from PEI
       California in connection with the private placement offering described in
       footnote (a) above, 13,459 shares underlie warrants transferred to the
       holder by Cagan-McAfee Capital Partners, LLC that were initially acquired
       from PEI California in connection with the private placement offering
       described in footnote (b) above and 11,750 shares underlie warrants
       transferred to the holder by Cagan-McAfee Capital Partners, LLC that were
       initially acquired from PEI California in connection with the private
       placement offering described in footnote (c) above. Chadbourn Securities,
       Inc. and Cagan-McAfee Capital Partners, LLC acted as placement agents and
       initially received these warrants as compensation for services performed
       in connection with the private placement offerings described in footnotes
       (a), and (b) and (c), above, respectively. In connection with its March
       2005 offering, PEI California entered into an agreement with Chadbourn
       Securities, Inc. for placement agent services. Under this agreement, PEI
       California agreed to pay to Chadbourn Securities, Inc. 2% of gross
       proceeds plus a 1% non-accountable expense allowance as well as warrants
       exercisable at the offering price in an amount equal to 3% of the
       aggregate number of shares of common stock sold in the private offering.
       Under this agreement, PEI California paid to Chadbourn Securities, Inc.
       approximately $625,000 and issued warrants to Chadbourn Securities, Inc.
       to purchase 212,700 shares of common stock at $3.00 per share. In April
       2004, PEI California entered into an agreement with Cagan-McAfee Capital
       Partners, LLC for advisory services. Under this agreement, PEI California
       agreed to pay to Cagan-McAfee Capital Partners, LLC 3% of any equity
       amount raised through the efforts of Cagan-McAfee Capital Partners, LLC.
       In connection with its March 2005 private placement, PEI California paid
       to Cagan-McAfee Capital Partners, LLC $235,000 and in connection with the
       Share Exchange Transaction, we paid approximately $85,000 to Cagan-McAfee
       Capital Partners, LLC. Differences between us, on the one hand, and
       Cagan-McAfee Capital Partners, LLC and Chadbourn Securities, Inc., on the
       other, arose as to what fees, if any, we would owe to Cagan-McAfee
       Capital Partners, LLC and/or Chadbourn Securities, Inc., under the
       advisory agreement in the event that our sale of Series A Cumulative
       Redeemable Convertible Preferred Stock to Cascade Investment, L.L.C., as
       described elsewhere in this prospectus, is completed. See "Description of
       Capital Stock - Series A Preferred Stock." Under a Settlement Agreement
       and Release with Cagan-McAfee Capital Partners, LLC and Chadbourn
       Securities, Inc. dated November 1, 2005, we terminated the advisory
       agreement with Cagan-McAfee Capital Partners, LLC on November 1, 2005,
       subject to completion of our transaction with Cascade Investment, L.L.C.,
       and made a payment of $150,000 in accelerated monthly consulting fees
       under the advisory agreement. In addition, in connection with the
       termination of the advisory agreement, we agreed that, in the event that
       our transaction with Cascade Investment, L.L.C. is completed, we would
       pay to Cagan-McAfee Capital Partners, LLC $960,000 within five business
       days of the closing. Under the Settlement Agreement and Release, in the
       event that our transaction with Cascade Investment, L.L.C. does not close
       by March 31, 2006, the advisory agreement will be reinstated. Also,
       certain founders of PEI California agreed to sell an aggregate of 500,000
       shares of common stock owned by them to Cagan-McAfee Capital Partners,
       LLC for a purchase price of $0.01 per share for securing financing to
       close the Share Exchange Transaction. Immediately prior to the
       consummation of the Share Exchange Transaction, these founders sold these
       shares to Cagan-McAfee Capital Partners, LLC at the agreed upon price.
       Prior to the aforementioned transactions, PEI California paid fees of
       $100,000 to Cagan-McAfee Capital Partners, LLC in connection with other
       private placement offerings and issued warrants to Cagan-McAfee Capital
       Partners, LLC to purchase 50,000 shares of common stock at $2.00 per
       share.
(l)    The shares of common stock offered by the selling security holder
       hereunder underlie warrants transferred to the holder by Cagan-McAfee
       Capital Partners, LLC that were initially acquired from PEI California in
       connection with the private placement offering described in footnote (c)
       above. Cagan-McAfee Capital Partners, LLC acted as a placement agent and
       initially received these warrants as compensation for services performed
       in connection with the private placement offering described in footnote
       (c) above. See also footnote (h) above.
(82)   Includes 223,949 shares underlying warrants. Also includes 512,500 held
       directly by Laird Q. Cagan. 
(86)   Represents shares underlying warrants. Power to vote or dispose of the
       shares is held by Lara S. Coviello as President of Fairmont Analytics,
       Inc.
