            AMENDED AND RESTATED CONTINUING REIMBURSEMENT AGREEMENT

       THIS AMENDED AND RESTATED CONTINUING REIMBURSEMENT AGREEMENT (this
"AGREEMENT"), dated as of November 12, 1996, is by and between F. C. Schaffer &
Associates Inc., a Louisiana corporation (the "CUSTOMER"), and ABN AMRO Bank,
N.V., a Netherlands chartered bank, acting through its Houston Agency (the
"BANK").

                                   WITNESSETH

       A.     The Customer and the Bank have entered into that certain
Continuing Reimbursement Agreement dated as of November 1, 1994 (the "PRIOR
AGREEMENT").

       B.     This Agreement amends, restates and supersedes the Prior
Agreement in its entirety.

       C.     The Bank and Principal Mutual Life Insurance Company, TMG Life
Insurance Company, Berkshire Life Insurance Company and The Security Mutual
Life Insurance Company (collectively, together with any successors or assigns
thereto, the "NOTEHOLDERS"), and Texas Commerce Bank National Association and
Bank One Texas, N.A. (collectively, together with any successors or assigns
thereto, the "BANK GROUP") have entered into an Intercreditor Agreement of even
date herewith (the "INTERCREDITOR AGREEMENT").

       WHEREAS, the Customer and the Bank hereby agree as follows:

       1.     SCOPE OF THIS AGREEMENT.  The Customer has previously requested
that the Bank issue, and the Bank has so issued, four letters of credit for the
Customer's account and for the benefit of The General Manager, Finchaa Sugar
Factory of the Transitional Government of Ethiopia in connection with that
certain Contract No. FP-03 for the Design, Supply, Construction and
Commissioning of Finchaa Sugar Factory and Ethanol Plant (the "CONTRACT") dated
as of October 4, 1994, by and between the Customer and Finchaa Sugar Factory of
the Transitional Government of Ethiopia (now known as the Finchaa Sugar Factory
Project of the Federal Democratic Republic of Ethiopia) (the "FINCHAA SUGAR
FACTORY"), two performance security letters of credit in the original face
amounts of $7,001,681 USD and 7,540,406 Birr (collectively, as heretofore
amended, the "PERFORMANCE SECURITY LETTER OF CREDIT") and two advance payment
letters of credit in the original face amounts of $14,003,364 USD and
15,080,813 Birr (collectively, as heretofore amended, the "ADVANCE PAYMENT
LETTER OF CREDIT").  The Bank has also issued, at the request of the Finchaa
Sugar Factory, a letter of credit for the benefit of the Customer as a method
of disbursement of certain sums due to it from the Finchaa Sugar Factory under
the Contract in connection with Finchaa Sugar Factory and Ethanol Plant (the
"FINCHAA PROJECT"), the draws under which are reimbursed and guaranteed by the
African Development Bank ("ADB") (as heretofore amended, the "REVOLVING LETTER
OF CREDIT") (the Performance Security Letter of Credit, the Advance Payment
Letter of Credit and the Revolving Letter of Credit are sometimes hereinafter
referred to as a "LETTER OF CREDIT" or collectively as the "LETTERS
<PAGE>   2
OF CREDIT").  The issuance of, and the agreement to issue, the Letters of
Credit in response to such requests shall be deemed to incorporate by reference
and to have been made automatically subject to the terms and conditions of this
Agreement.  Each of the terms, conditions, and obligations in the applications
with respect to the Performance Security Letter of Credit and the Advance
Payment Letter of Credit shall be incorporated herein with respect to such
Letter of Credit issued and shall constitute obligations of the Customer
hereunder.  To the extent of any inconsistency between any of such applications
and this Agreement, the terms and provisions of this Agreement shall prevail.
The Customer hereby acknowledges and agrees that the Finchaa Sugar Factory has
requested that the expiry date of the Revolving Letter of Credit be extended to
April 23, 1998, and the Revolving Letter of Credit has been so extended, and it
hereby agrees to such amendment.

       2.     REIMBURSEMENT.  The Customer agrees to reimburse the Bank,
immediately upon written demand, for any payment the Bank makes under the
Performance Security Letter of Credit or the Advance Payment Letter of Credit.
The Customer also agrees to reimburse the Bank, immediately upon written
demand, for any reasonable expense the Bank incurs in connection with making
payment under either such Letter of Credit.  All payment obligations of the
Customer hereunder shall be in United States Dollars, converted, if necessary,
from Birr to United States Dollars on the date of payment of any draw under the
Performance Security Letter of Credit or the Advance Payment Letter of Credit,
as the case may be, at the exchange rate paid by the Bank to purchase the Birr
necessary to cover any such draw.

       3.     ISSUANCE FEES AND RESTRUCTURE FEE.  The Customer agrees to pay to
the Bank with respect to each of the Advance Payment Letter of Credit and the
Performance Security Letter of Credit a nonrefundable fee, quarterly in advance
commencing as of October 1, 1996, and quarterly thereafter, equal to the higher
of 2.0% per annum or the rate per annum for the issuance of letters of credit
provided for in the First Amended and Restated Credit Agreement among Serv-
Tech, Inc. ("SERV-TECH"), the Guarantors named therein, Texas Commerce Bank
National Association ("TCB"), as Agent, and the Bank Group dated as of November
12, 1996 (the "BANK AGREEMENT") of the face amount of each such Letter of
Credit at the beginning of each calendar quarter calculated on the basis of a
365-day year and the actual days in such calendar quarter and based on the
scheduled expiration of such Letter of Credit.  The Customer also agrees to pay
to the Bank with respect to the Revolving Letter of Credit a nonrefundable fee,
quarterly in advance commencing as of October 1, 1996, and quarterly
thereafter, equal to 1/2% per annum of the $12,500,000 face amount thereof or
such reduced face amount thereof pursuant to the terms of the Revolving Letter
of Credit, at the beginning of each calendar quarter calculated on the basis of
a 365-day year and the actual days in such calendar quarter and based on the
scheduled expiration of such Letter of Credit.  The Customer agrees to pay to
the Bank a nonrefundable restructure fee of $113,965.27 as a condition
precedent to the effectiveness of this Agreement.

       4.     POST-ISSUANCE COSTS.  The Customer agrees to pay to the Bank,
immediately upon written demand, any and all reasonable costs arising after
issuance of any Letter of Credit that the Bank may reasonably pay or incur
under or in connection with a Letter of Credit or this





                                      -2-
<PAGE>   3
Agreement, including, without limitation, reasonable legal fees arising from
the enforcement of this Agreement.  If the Bank determines that the effect of
any change from the date hereof in any applicable law, governmental regulation,
guideline or order or in the interpretation thereof by any governmental
authority charged with the administration thereof (including the imposition of
or change in any reserve, capital, special deposit, insurance, or similar
requirement) is to increase the cost of issuing or maintaining any Letter of
Credit, to reduce the Bank's return on its capital as a result of so issuing or
maintaining any Letter of Credit, or to reduce the amount of any payment to be
made to the Bank in respect of any obligation hereunder, then the Customer will
pay to the Bank, on demand, such additional amounts as the Bank may determine
to be required to compensate the Bank on an after-tax basis for such additional
cost or reduction of amounts receivable hereunder.  Any additional payments
under this clause will be computed in accordance with generally accepted
accounting principles ("GAAP") from the effective date at which such additional
costs or reduction in amounts receivable have to be borne by the Bank.

       5.     INTEREST.  (a) The Customer agrees to pay to the Bank, without
demand unless otherwise specified below, interest on all amounts due from it
but unpaid hereunder as set forth below:

              (i)    All amounts drawn under the Revolving Letter of Credit
       from the date of such draw until the date such amount is reimbursed by
       the ADB shall bear interest, payable upon written demand on the last
       business day of each calendar month after any such draw, at a daily
       fluctuating interest rate per annum equal to the higher of (a) the
       fluctuating overnight money market rate of interest announced by the
       Bank from time to time at its Chicago, Illinois office in effect on such
       day, or (b) the sum of (x) the rate per annum (rounded upwards, if
       necessary, to the nearest 1/100th of 1%) equal to the weighted average
       of the rates on overnight Federal funds transactions with members of the
       Federal Reserve System arranged by Federal funds brokers on such day, as
       published by the Federal Reserve Bank of New York on the next business
       day on which the Bank is open, provided, that (A) if such day is not
       such a business day, the rate on such transactions on the immediately
       preceding business day as so published on the next business day shall
       apply, and (B) if no such rate is published on such next business day,
       the rate for such day shall be the average rate quoted to the Bank by
       three (3) members of the Federal Reserve System on such day for such
       transactions as determined by the Bank, plus (y) 0.50% per annum (the
       "FEDERAL FUNDS RATE");

              (ii)   All amounts drawn under the Performance Security Letter of
       Credit from the date of such draw until the date such amount is
       reimbursed by the Customer shall bear interest at a daily fluctuating
       interest rate per annum equal to the higher of the fluctuating
       commercial loan rate of interest announced by the Bank from time to time
       at its Chicago, Illinois office as its base rate for U.S. Dollar loans
       in the United States of America in effect on such day (which rate is not
       necessarily its lowest rate charged by the Bank on loans to any of its
       customers) or the Federal Funds Rate (the "BASE RATE") plus 3% per
       annum; and





                                      -3-
<PAGE>   4
              (iii)  All amounts drawn under the Advance Payment Letter of
       Credit shall bear interest from the date of such draw until the date
       such amount is reimbursed by the Customer at a daily fluctuating
       interest rate per annum equal to the Base Rate plus 3% per annum.

       6.     USURY SAVINGS CLAUSE.  If at any time the interest rate
applicable to any amount outstanding hereunder exceeds the maximum rate or the
amount of interest which the Bank is allowed by law to contract for, charge,
take, reserve or receive (the "HIGHEST LAWFUL RATE"), the rate of interest on
such outstanding amount shall be limited to the Highest Lawful Rate, but any
subsequent reductions in the interest rate shall not reduce the rate of
interest thereon below the Highest Lawful Rate until the total amount of
interest accrued thereon equals the amount of interest which would have accrued
thereon if the interest rate had at all times been in effect.  In the event
that at maturity (stated or by acceleration), or at final payment of all
obligations hereunder, the total amount of interest paid or accrued thereon is
less than the amount of interest which would have accrued thereon if the
interest rate applicable thereto had at all times been in effect, then, at such
time and to the extent permitted by law, the Customer shall pay an amount equal
to the difference between (a) the lesser of the amount of interest which would
have accrued thereon if the interest rate applicable thereto had at all times
been in effect and the amount of interest which would have accrued thereon if
the Highest Lawful Rate had at all times been in effect, and (b) the amount of
interest actually paid or accrued on all obligations hereunder.  To the extent
that Article 5069-1.04 of the Texas Revised Civil Statutes is relevant to the
Bank for the purpose of determining the Highest Lawful Rate, the Bank hereby
elects to determine the applicable rate ceiling under such Article by the
indicated (Weekly) rate ceiling from time to time in effect, subject to its
right subsequently to change such method in accordance with applicable law.  To
the extent the interest received hereunder exceeds the Highest Lawful Rate, the
Bank shall refund to the Customer the amount of the excess or shall credit the
amount of the excess against amounts owing hereunder and the Bank shall not be
subject to any of the penalties provided by law for contracting for, taking,
reserving, charging or receiving interest in excess of the Highest Lawful Rate.

       7.     PAYMENTS.  All payments by the Customer to the Bank hereunder
shall be made in immediately available U.S. Dollars at the Bank's office as set
forth on the signature page hereto or at such other place within the
continental United States of America as the Bank may designate in writing,
without any withholding, deduction, or set off.  The Bank may open and debit
(under written advice to the Customer) a new account in the name of the
Customer to effect such payments in respect of the Customer's obligations
hereunder.

       8.     WAIVER OF EXISTING KNOWN DEFAULTS.  The Customer has disclosed in
writing to the Bank all defaults and Events of Default that may exist under the
Prior Agreement and the Guaranty dated as of November 1, 1994, executed in
connection therewith (the "PRIOR GUARANTY") immediately prior to closing under
this Agreement.  The Bank, in consideration of the agreements of the Customer
hereunder, hereby waives each such default or Event of Default.





                                      -4-
<PAGE>   5
The Bank hereby represents and warrants to the Customer that, as of closing
hereunder, it knows of no other default or Event of Default under the Prior
Agreement or the Prior Guaranty, and no default or Event of Default resulting
from the execution and delivery of this Agreement or any of the other
documentation executed and delivered at closing  or transactions effected.  It
is agreed and understood that such waivers of defaults or Events of Default by
the Bank shall not constitute a waiver of any other default or Event of Default
under the Prior Agreement or the Prior Guaranty or any similar or future
default or Event of Default hereunder or under the Amended and Restated
Guaranty of even date herewith.

       9.     RELEASE AND INDEMNITY.  (a) The Customer for itself and its
directors, officers, employees, shareholders, agents, successors, assigns,
other representatives, affiliates and attorneys do hereby release and forever
discharge the Bank and its directors, officers, employees, shareholders,
agents, successors, assigns, other representatives, affiliates and attorneys
(each a "RELEASED PARTY") from any and all losses, claims, demands, damages,
causes of actions, actions, cross-actions, judgments, liabilities, penalties,
costs and expenses (including attorneys' fees and other legal expenses) of any
kind or nature whatsoever ("CLAIMS"), which any of such persons has owned or
held, or may now or in the future own or hold, whether known or unknown,
contingent or liquidated, for or because of any action, inaction, omission,
statement or publication on or before the date hereof by any Released Party
arising directly or indirectly out of any of the Letters of Credit or the Prior
Agreement, or any other documents or instruments executed in connection
therewith or any other transactions relating directly or indirectly thereto,
including, without limitation, any claims of usury which may or could be
asserted by any such persons.

              (b)    The Customer agrees to indemnify and hold harmless each of
the Released Parties, on demand and to the fullest extent permitted by law,
against all Claims which any of the Released Parties may pay or incur arising
directly or indirectly out of any of the Letters of Credit, the Prior
Agreement, this Agreement, any other documents or instruments executed in
connection therewith or any other transactions relating directly or indirectly
thereto, including, without limitation, actions commenced by Finchaa Sugar
Factory for wrongful dishonor or non-payment and actions commenced by Schaffer
to enjoin honor or payment to attach the proceeds of honor or payment or for
wrongful dishonor or non-payment, regardless of whether any of such Claims are
founded in whole or in part upon the alleged negligence of any of the Released
Parties other than those which arise from the gross negligence or willful
misconduct of the party claiming indemnification.  WITHOUT LIMITING ANY
PROVISION OF THIS AGREEMENT, IT IS EXPRESSLY INTENDED BY THE PARTIES THAT EACH
OF SUCH RELEASED PARTIES TO BE INDEMNIFIED HEREUNDER SHALL BE INDEMNIFIED AND
HELD HARMLESS AGAINST ANY AND ALL CLAIMS ARISING OUT OF OR RESULTING FROM THE
ORDINARY SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH RELEASED PARTY OR IMPOSED UPON
SUCH RELEASED PARTY UNDER ANY THEORY OF STRICT LIABILITY.  The Customer, upon
written demand by the Bank, shall reimburse the Bank for any legal or other
expenses incurred in connection with investigating or defending against any of
the foregoing except if the same is directly due to the gross negligence or
willful misconduct of the Released Party.

       16.    LIMITED LIABILITY.  So long as the Bank has exercised reasonable
care and has acted in good faith, the Bank shall not be responsible to the
Customer for, and the Bank's right to reimbursement, indemnification, and other
payments hereunder shall not be impaired by (i) any act or omission for which
banks are relieved of responsibility under the Uniform Customs and Practice for
Documentary Credits, 1993 revision, ICC Publication No. 500 (1993), (ii) any





                                      -16-

recommendation or failure to recommend the inclusion or exclusion of any
particular term or wording in a Letter of Credit, (iii) honor or dishonor or
refusal of any demand under a Letter of Credit following the Customer's refusal
to confirm that such demand is entitled to be honored or that the Bank is
entitled to be reimbursed, (iv) any lack of validity or enforceability of this
Agreement or document or instrument executed in connection therewith, (v) any
amendment or waiver of or any consent to depart from all or any of the
provisions of this Agreement or any document or instrument executed in
connection therewith; (vi) the existence of any claim, set-off, defense or
other right the Customer may have at any time against a beneficiary of a Letter
of Credit (or any person for whom a beneficiary may be acting), the Bank or any
other person, whether in connection with this Agreement, another document or
instrument executed in connection therewith or any unrelated transaction; (vii)
any statement or any other document presented under a Letter of Credit proving
to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect; (viii) payment by
the Bank under a Letter of Credit against presentation to the Bank of a draft
or certificate that does not comply with the terms of the Letter of Credit,
provided that the Bank's determination that documents presented under the
Letter of Credit comply with the terms thereof did not constitute gross
negligence or willful misconduct of the Bank; or (ix) any other act or omission
to act or delay of any kind by the Bank or any other person or any other event
or circumstance whatsoever that might, but for the provisions of this Section,
constitute a legal or equitable discharge of the Customer's obligations
hereunder.  The Bank shall not be liable for any special, indirect, or
consequential damages unless there is a judicial finding by a court of
competent jurisdiction that such damages resulted solely from the Bank's bad
faith or willful misconduct.

       17.    MISCELLANEOUS.

              (a)    NO WAIVER; AMENDMENT.  No amendment or waiver of any
       provision hereof shall be enforceable against the Bank unless in writing
       and signed by the Bank, and then only in the specific instance and for
       the specific purposes for which given.  Nothing herein shall affect the
       Bank's duties or a beneficiary's rights under a Letter of Credit unless
       such Letter of Credit is so amended.

              (b)    APPLICABLE LAW AND VENUE.  THIS AGREEMENT SHALL BE

       arising out of or relating to this Agreement may be brought in a court
       of competent jurisdiction in the State of Texas or in the Courts of the
       United States of America located in such State, and that any suit,
       action or other legal proceeding arising out of or relating to any
       Letter of Credit issued hereunder may be brought, at the option of the
       Bank, either in such a court or any other appropriate court of competent
       jurisdiction, (ii) consents to the jurisdiction of any such court in any
       such suit, action or proceeding, and (iii) waives any objection or
       immunity which it may have to the laying of

       venue of any suit, action or proceeding in any of such courts and any

       all of which together shall constitute one and the same document.

              (d)    SEVERABILITY.  Any provision of this Agreement which is
       prohibited or unenforceable in any jurisdiction shall, as to such

       unenforceability without invalidating the remaining provisions of this
       Agreement, and any such prohibition or unenforceability in any
       jurisdiction shall not invalidate or render unenforceable such provision
       in any other jurisdiction.

              (e)    SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All
       representations and warranties made in this Agreement or in any
       certificate delivered pursuant hereto shall survive the execution and
       delivery of this Agreement, and no investigation by the Bank shall
       affect the representations and warranties or the right of the Bank to
       rely upon them.

              (f)    HEADINGS.  Section headings used in this Agreement are for

       WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR LEGAL PROCEEDING
