EXHIBIT 10.52

                    AMENDED AND RESTATED TERM LOAN AGREEMENT
             (LYLES DIVERSIFIED, INC. - PACIFIC ETHANOL MADERA LLC)

                  THIS AMENDED AND RESTATED TERM LOAN AGREEMENT (this
"Agreement") is made effective as of April 13, 2006, by and between LYLES
DIVERSIFIED, INC., a California corporation ("Lender") and PACIFIC ETHANOL
MADERA LLC, a Delaware limited liability company ("Borrower").

                                R E C I T A L S:
                                 - - - - - - - -

                  A. Pacific Ethanol California, Inc., a California corporation
(formerly known as Pacific Ethanol, Inc., "PEI California") and Borrower are,
respectively, direct and indirect wholly-owned subsidiaries of Pacific Ethanol,
Inc., a Delaware corporation ("PEIX").

                  B. PEI California and Lender are parties to the Term Loan
Agreement, dated as of June 16, 2003 (the "Original Agreement"); the Original
Agreement was assigned to PEIX by PEI California pursuant to the Assignment of
Term Loan Agreement and Deed of Trust, dated as of March 23, 2005, by and among
PEIX, PEI California, William L. Jones and Lender.

                  C. PEI California owns certain real property consisting of
approximately 137 acres located in Madera County, California, on Avenue 12 about
four miles east of Highway 99 (the "Real Property"). The Real Property includes
certain improvements and fixtures, including, but not limited to, a grain
storage and processing facility, an office building, and two railroad sidings.
Concurrently with the execution of this Agreement, PEI California will
contribute the Real Property to Borrower pursuant to a grant deed.

                  D. Borrower is developing a denatured ethanol production
facility on the Real Property (the "Madera Facility"). Borrower and its
affiliates intend, at some future date, to construct a second ethanol production
facility in California (the "Second Facility"). Borrower has selected W.M. Lyles
Co. ("Builder") as the general contractor for the Madera Facility and the Second
Facility. Lender is the parent company of Builder. Borrower and Builder are
parties to the Amended and Restated Phase 1 Design-Build Agreement and the Phase
2 Design-Build Agreement, each dated as of November 2, 2005 (collectively, the
"Design-Build Contract"), pursuant to which Builder is providing design-build
services to Borrower for the construction of the Madera Facility. Borrower or
one of its affiliates and Builder intend, at a later date, to enter into a
second design-build contract for the Second Facility.

                  E. Borrower will obtain the financing necessary to complete
the construction of the Madera Facility pursuant to the Construction and Term
Loan Agreement of even date herewith (the "HUD Loan Agreement") by and among
Borrower, the lenders from time to time party thereto and Hudson United Capital,
a Division of TD Banknorth, N.A., a national banking association, as
administrative agent for the lenders (the "Administrative Agent").

                  F In order for Borrower to complete the financing for the
construction of the Madera Facility, Lender has agreed to amend and restate the
Original Agreement to, among other things, (i) transfer the loan from PEIX to
Borrower and (ii) subordinate its rights, remedies and security interest
hereunder and under the Deed of Trust (as defined herein) to the rights,
remedies and security interest of the lenders under the HUD Loan Agreement.

                  NOW THEREFORE, in consideration of the mutual terms and
conditions contained herein, the parties agree as follows:

                                    SECTION 1

                                   FACILITIES

                  1.1 THE TERM LOAN: Lender agrees to make a term loan to
Borrower in the amount of $5,100,000.00. The credit facility described in this
Section shall be referred to below as the "Term Loan". Borrower will pay
interest on all amounts owing under the Term Loan until payment in full of any
principal outstanding thereunder. Lender and Borrower acknowledge and agree
that, as of the date hereof, the outstanding principal amount of the term loan
is $3,600,000.

                  1.2 INITIAL ADVANCE; DEPOSIT: On March 24, 2003 Lender made an
initial advance to Borrower under the Term Loan in the principal amount of
$510,000.00, which PEI California used as a good-faith deposit for the purchase
of the Real Property (the "Deposit"). Interest will accrue from March 24, 2003
on the principal amount of the Deposit, at the rates indicated in Paragraph 1.3
of this Agreement.

                  1.3 REPAYMENT TERMS:

                           (a) INTEREST RATE. Interest under the Term Loan will
         accrue at the following rates:

                                    (1) A rate of five percent (5.00%) per annum
                  through June 19, 2004.

                                    (2) A rate per annum equal to the "Wall
                  Street Journal Prime Rate" (as defined in Section 1.2(b)) plus
                  two percentage points (2.00%) from June 20, 2004 until the
                  Maturity Date (as defined in Section 1.3(d)).

                           (b) DEFINITION OF WALL STREET JOURNAL PRIME RATE. The
         "Wall Street Journal Prime Rate" for any day is a fluctuating rate of
         interest equal to the highest rate published from time to time in the
         "Money Rates" section of The Wall Street Journal as the Prime Rate for
         such day (or, if such source is not available, such alternate source as
         determined by Lender).

                           (c) COMPUTATION AND PAYMENT OF INTEREST. Interest
         shall be based on a 365 day year and compounded monthly. Interest shall
         be paid monthly commencing on June 20, 2004, and continuing on the
         twentieth (20th) day of each month thereafter. If interest is not paid
         as it becomes due, it may be added to, become and be treated as a part
         of the principal, and shall thereafter bear like interest.

                                       2

<PAGE>

                           (d) PRINCIPAL PAYMENTS/MATURITY DATE. One third of
         the principal outstanding on June 20, 2006 shall be paid on that date.
         Half of the principal outstanding on June 20, 2007 shall be paid on
         that date. All remaining outstanding principal, together with any
         accrued interest thereon, shall be due and payable on June 20, 2008,
         (the "Maturity Date").

                           (e) ADDITIONAL PRINCIPAL PAYMENTS. Borrower shall be
         required to prepay the principal owing under the Term Loan in the
         following circumstances:

                                    (i) should the construction cost for the
                  Madera Facility to be constructed on the Real Property be less
                  than $42.6 million then Borrower shall promptly pay lender the
                  difference between the actual construction cost and $42.6
                  million; and

                                    (ii) should Borrower or any of its
                  affiliates obtain construction funding for the Second
                  Facility, Borrower shall promptly pay Lender all principal and
                  accrued interest then outstanding.

                  1.4 PREPAYMENT: Borrower may prepay any amount owing under the
Term Loan, in whole or in part, at any time and without penalty, provided,
however, that any partial prepayment shall first be applied, at Lender's option,
to accrued and unpaid interest and next to the outstanding principal balance.

                  1.5      [INTENTIONALLY OMITTED.]

                  1.6 PAYMENT: If any payment required to be made by Borrower
hereunder becomes due and payable on a day other than a Business Day (as defined
below), the due date thereof shall be extended to the next succeeding Business
Day and interest thereon shall be payable at the then applicable rate during
such extension. Both principal and interest are payable in lawful money of the
United States of America in same day funds at any place that Lender may, from
time to time, in writing designate. "Business Day" shall mean a day, other than
a Saturday or Sunday, on which commercial Lenders are open for business in
California.

                  1.7 DEFAULT RATE: If any amount owing under the Term Loan is
not paid when due, whether at stated maturity, by acceleration, or otherwise,
will bear interest from the date on which that amount is due until the amount is
paid in full, payable on demand, at a rate which is two percent (2.00%) in
excess of the rate or rates then in effect (the "Default Rate").

                  1.8 LATE PAYMENT: In addition to any other rights Lender may
have hereunder, if any payment of principal or interest, or any portion thereof,
under this Agreement is not paid in accordance with the terms herein, a late
payment charge equal to five percent (5%) of such past due payment may be
assessed and shall be immediately payable.

                                    SECTION 2

                     COLLATERAL, SUBORDINATION AND GUARANTY

                  2.1 REAL PROPERTY SECURITY: Borrower agrees to execute and
deliver to Lender a deed of trust dated concurrently with this Agreement (the
"Deed of Trust") granting to Lender a security interest in the Real Property
(the "Collateral"), to secure the payment and performance of the obligations

                                       3

hereunder. Notwithstanding any provision to the contrary herein, Lender
acknowledges and agrees that the lien created by the Deed of Trust is subject
and subordinate to the lien created by that certain Deed of Trust, Assignment of
Lease and Rents and Security Agreement of even date herewith, made by Borrower
to Chicago Title Company, as trustee, for the benefit of the Administrative
Agent, as beneficiary.

                  2.2 SUBORDINATION TO FINANCING: Notwithstanding any provision
to the contrary herein, Lender acknowledges and agrees that all of its rights
and remedies under this Agreement shall be governed by, and subject to, that
certain Intercreditor and Collateral Sharing Agreement of even dated herewith by
and between Lender and the Administrative Agent.

                  2.3 [INTENTIONALLY OMITTED.]

                  2.4 ADDITIONAL CONSIDERATION: As additional consideration,
Borrower agrees it will, or will cause its affiliates to engage Lender at the
appropriate time, on mutually acceptable terms substantially similar to the
Design-Build Contract for the Madera Facility, on a design-build agreement for
the Second Facility irrespective of whether the Term Loan is repaid at the time
Borrower or its affiliates is prepared to contract for the design and
construction of that facility.

         Re:      Madera Project - Amended and Restated Term Loan Agreement
                  ---------------------------------------------------------

Ladies and Gentlemen:

                  Reference is made to (a) that certain Amended and Restated
Term Loan Agreement, dated as of April 13, 2006 (as amended, supplemented,
amended and restated or otherwise modified from time to time, the "LDI LOAN
AGREEMENT"), between Pacific Ethanol Madera LLC, a Delaware limited liability
company ("MADERA"), and Lyles Diversified, Inc., a California corporation
("LENDER") and (b) that certain Intercreditor and Collateral Sharing Agreement,
dated as of April 13, 2006 (the "INTERCREDITOR AGREEMENT"), by and among
Lender and Hudson United Capital, a Division of TD Banknorth, N.A., a national
banking association, as the agent pursuant to the Construction and Term Loan
Agreement, dated as of April 10, 2006 (the "HUC LOAN AGREEMENT"), by and
among Madera, HUC and the lenders from time to time party thereto. Unless
otherwise defined herein, capitalized terms used in this letter agreement have
the meanings provided to such terms in the LDI Loan Agreement.

                  As contemplated by and more particularly provided for in the
Intercreditor Agreement, Lender has agreed to completely subordinate its lien in
the Collateral and its rights under the LDI Loan Agreement to the rights of the
Senior Lenders (as defined in the Intercreditor Agreement) under the HUC Loan
Agreement.

                  In consideration for Lender's subordination of its lien and
the waiver of its rights under the LDI Loan Agreement pursuant to the terms of
the Intercreditor Agreement, the undersigned agrees that, in the event that
Madera is prevented from making any principal payment due to Lender by the
operation of the terms of the Intercreditor Agreement, the undersigned shall
repay to Lender all principal then due under the Term Loan (the "REPAYMENT
OBLIGATION"). In the event the undersigned fails to pay the Repayment Obligation
to Lender within 3 Business Days of the date such Repayment Obligation arises,
then, from and after such date, the outstanding amount of such Repayment
Obligation shall accrue interest at a per annum rate equal to the Default Rate
PLUS 5% per annum until such time as the Repayment Obligation is paid in full.
Lender further acknowledges and agrees that Madera shall not be responsible for
the payment of the Repayment Obligation or any interest thereon.

                  This letter agreement shall be governed by, and shall be
construed and enforced in accordance with, the internal laws of the State of
California, without regard to conflicts of laws principles. Any disputes or
controversies arising under this letter agreement shall be resolved in
accordance with and subject to the dispute resolution provisions set forth in
the LDI Loan Agreement.

                  This letter agreement and any agreement, document or
instrument attached hereto or referred to herein integrate all the terms and
conditions mentioned herein or incidental hereto and supersede all oral
negotiations and prior writings in respect to the subject matter hereof. In case
any one or more of the provisions contained in this letter agreement should be
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby, and the parties hereto shall enter into good faith
negotiations to replace the invalid, illegal or unenforceable provision with a
view to obtaining the same commercial effect as this letter agreement would have
had if such provision had been legal, valid and enforceable. No amendment or
waiver of any provision of this letter agreement shall be effective unless such
amendment or waiver is in writing and signed by each of the parties hereto. This
letter agreement shall be binding upon and shall inure to the benefit of each of
the parties hereto, Madera and their respective successors or assigns.

                  This letter agreement may be executed in counterparts, each of
which shall constitute an original but all of which when taken together shall
constitute one contract. Delivery by facsimile by any of the parties hereto of
an executed counterpart of this letter agreement shall be as effective as an
original executed counterpart hereof.

                            (SIGNATURE PAGE FOLLOWS)
