                           REVOLVING CREDIT AGREEMENT


         THIS REVOLVING CREDIT AGREEMENT is entered into as of February ___,
1997, by and among UNIMARK FOODS, INC., a Texas corporation which is the
Borrower, and THE UNIMARK GROUP, INC., a Texas corporation ("GROUP"), UNIMARK
INTERNATIONAL, INC., a Texas corporation and a wholly-owned subsidiary of
Group, and SIMPLY FRESH FRUIT, INC., a California corporation and a
wholly-owned subsidiary of Borrower (each of which shall be a "GUARANTOR"
hereunder and which collectively shall be "GUARANTORS"); and COOPERATIEVE
CENTRALE RAIFFEISEN-BOERENLEENBANK B.A., "RABOBANK NEDERLAND," NEW YORK BRANCH,
a Federally Licensed Branch of a Netherlands Cooperative Banking Organization
which is the Lender.

                                P R E A M B L E:

         As Group is the parent of and owns 100% of the issued and outstanding
capital stock of UniMark International, Inc. ("INTERNATIONAL"), UniMark Foods,
Inc., which is the Borrower, and Les Produits Deli-Bon, Inc. ("DELI-BON"), a
Canadian corporation, and 99% of the issued and outstanding capital stock of
AgroMark, S.A. de C.V., a Mexican corporation ("AM"), and Industrias Citricolas
de Montemorelos, S.A. de C.V., a Mexican corporation ("ICMOSA"), and Grupo
Industrial Santa Engracia, S.A. de C.V. ("GISE"), a Mexican corporation, and
UniMark Foods, Inc. is the parent and owns 100% of the issued and outstanding
capital stock of Simply Fresh Fruit, Inc. ("SIMPLY FRESH"), with the Group and
said Subsidiaries of Group being referred to collectively herein as "UNIMARK";

         As UniMark is a vertically integrated citrus and tropical fruit,
growing, processing, marketing, and distributing company with operations in
Mexico, the United States, and Canada.  UniMark's business strategy is as is
set forth on page 3 of that Prospectus Summary issued by UniMark and dated June
14, 1996;

         As ICMOSA and GISE, as subsidiaries of Borrower, are currently
indebted to Lender for separate amounts of working capital needed for their
respective operations in Mexico and the separate indebtedness of each company
is secured by respective assets of each;

         As UniMark Foods, Inc. now desires to borrow additional monies from
Lender for the working capital needs of the Borrower and of UniMark
International, Inc. and Simply Fresh Fruit, Inc. each of which is a Subsidiary
of Group located in the USA and Group and such Subsidiaries will benefit
directly or indirectly from such loan;

         As International is solvent but its assets and liabilities are an
immaterial portion of the total assets and liabilities of





REVOLVING CREDIT AGREEMENT, PAGE 1
<PAGE>   7
UniMark taken as a whole and will remain so until such loan to Borrower is paid
in full to Lender;

         As Group on behalf of UniMark taken as a whole enterprise has
requested that Lender make such a loan to the Borrower so that Borrower can
make loans to the other Subsidiaries of Group located in the USA so that Group
and the other Subsidiaries in the USA may utilize the loan proceeds to provide
a market in the USA for the products of the Mexican Subsidiaries of Group and
to distribute the products of the Subsidiaries in the USA and of the Mexican
Subsidiaries in the Canadian market through the Canadian Subsidiary Deli-Bon
(with Borrower, International and Simply Fresh being known herein collectively
as the "USA SUBSIDIARIES"); and

         As to induce Lender to make such loan, UniMark, through the Group and
Borrower, has offered the assets and guaranty of Group and the assets and
guaranties of the USA Subsidiaries as collateral for the loan to Borrower, and
therefore Group will and will cause its other Subsidiaries in the USA to secure
and guarantee the loan to Borrower to obtain the benefit of such loan not only
for UniMark as an enterprise but also for the direct benefit to each of the USA
Subsidiaries;

         Now, therefore, in consideration of the Preamble and the mutual
agreements herein contained, the parties hereto agree as follows:


                                   ARTICLE I

                                   ARTICLE II
                           AMOUNT AND TERMS OF LOANS

         2.1     REVOLVING LOAN.  Subject to the terms and conditions of this
Agreement, the Lender agrees to extend credit to the Borrower on a revolving
basis in Dollars in one or more Advances from time to time during the
Availability Period of the Commitment, provided (i) unless earlier terminated
pursuant to the terms hereof, the Commitment shall terminate on the Expiration
Date; (ii) neither the Commitment nor the Revolving Credit Obligations shall
exceed $8,500,000; (iii) the Revolving Credit Obligations shall not exceed the
lesser of the Borrowing Base or the Commitment; (iv) the Borrower may not
obtain a Cash Advance or cause a Letter of Credit to be issued which exceeds
the Availability at the time in question; (v) the Lender is not obligated to
fund any Advance at any time when any Interest Rate Option exceeds the Legal
Maximum; and (vi) each Cash Advance shall be in an amount of not less than
$100,000 or an integral multiple thereof.  Within the limits of this Section,
during the Availability Period the Borrower may borrow, repay, and reborrow in
accordance with the terms and conditions of this Agreement.

         2.2     REVOLVING NOTE.  The Advances made by the Lender shall be
evidenced by a Revolving Note executed by the Borrower which is dated the date
hereof, is in the amount of the Commitment, is payable to the order of the
Lender at the office of the Lender, and bears interest in accordance with the
terms thereof.  Notwithstanding the principal amount of the Revolving Note as
stated on the face thereof, the amount of principal actually owing on such
Revolving Note at any given time shall be the aggregate of all Advances
theretofore made to or for the benefit of the Borrower less all payments of
principal theretofore actually received hereunder by the Lender.  The Lender is
authorized, but is not required, to endorse on the schedule attached to the
Revolving Note appropriate notations evidencing the date and amount of each
Advance as well as the amount of each payment made by the Borrower thereunder.

         2.3     CASH ADVANCES.  The Borrower may from time to time request a
Cash Advance by delivering to the Lender the Borrower's completed and executed
Notice of Borrowing.  If the Borrower





REVOLVING CREDIT AGREEMENT, PAGE 3
<PAGE>   9
desires a Cash Advance on the Closing Date, the Notice of Borrowing shall be
delivered on the Closing Date.

         If the Borrower desires a Cash Advance be made on any other day, the
Notice of Borrowing shall be delivered as follows:

                 (a)      Except as provided in subsection (i) hereof, the
interest rate or rates applicable to each Tranche representing the Cash Advance
shall be established pursuant to a Notice of Borrowing which shall be delivered
to the Lender not later than 1:00 p.m. (New York City, New York time) on the
date it is required to be delivered and is irrevocable.

                          (i)     If the Interest Rate Option to be applicable
is the Base Rate or the Federal Funds Rate, the Notice of Borrowing shall be
delivered on the Funding Date (in the case of an Advance) or on the date of
renewal or conversion (in the case of a conversion to a Base Rate Tranche or a
Federal Funds Tranche).

                          (ii)    If the Interest Rate Option to be applicable
is the LIBOR Rate, the Notice of Borrowing shall be delivered not less than two
(2) Business Days prior to (A) the proposed Funding Date (in the case of an
Advance) or (B) the date of renewal or conversion (in the case of the renewal
of or conversion to a LIBOR Tranche).

                 (b)      Each Notice of Borrowing shall specify (i) the
Interest Rate Option selected; (ii) the Funding Date of the Advance or the
effective date of the renewal or conversion of the Interest Rate Option
applicable to the Tranche involved, which shall be a Business Day; (iii) the
amount of the Tranche representing such Cash Advance; (iv) the Interest Period
for such Tranche; and (v) the Borrower's disbursement instructions.

                 (c)      Each LIBOR Tranche shall be in a minimum amount of
TWO HUNDRED FIFTY THOUSAND AND 00/100 DOLLARS ($250,000) or in integral
multiples in excess thereof.

                 (d)      The Borrower may not have in effect in the aggregate
at any one time more than six (6) Tranches which may be comprised of any
combination of LIBOR Tranches, Base Rate Tranches and Federal Funds Tranches or
exclusively all of any one kind of Tranche, except that so long as any Default
or Event of Default continues, Borrower may not select the LIBOR Rate to apply
to any Tranche.

                 (e)      No renewal or conversion of a LIBOR Tranche may be
made except on the last day of the Interest Period applicable thereto.

                 (f)      The election of the LIBOR Rate is effective only for
the Interest Period specified; and after the end of such Interest Period,
unless the Borrower has effectively elected a renewal or





REVOLVING CREDIT AGREEMENT, PAGE 4
<PAGE>   10
conversion, the applicable Interest Rate Option shall be the Base Rate until
the Borrower effectively elects a different interest rate.

                 (g)      No election of or renewal of or conversion to a LIBOR
Rate may occur while any Default or Event of Default exists or if such
conversion would occur at a time when the Legal Maximum would be less than the
rate of interest which would be applicable to such LIBOR Tranche.

                 (h)      If the Borrower does not specify in accordance with
the terms hereof or is not entitled to elect the type of rate to apply to an
Advance or any portion of the Loan, as the case may be, the Borrower shall be
deemed to have specified the Base Rate for such Advance or portion of the Loan.

                 (i)      The Borrower shall at all times maintain a sufficient
amount as a Base Rate Tranche to allow the Borrower to make payments of
principal on a LIBOR Tranche or a Federal Funds Tranche which payments are
necessary to avoid paying any LIBOR Tranche prior to the end of its Interest
Period or which are necessary to pay any Federal Funds Tranche.

In lieu of delivering the Notice of Borrowing as described above (other than
any Notice of Borrowing for funding on the Closing Date), the Borrower may give
the Lender irrevocable telephonic notice of a request for a Cash Advance which
is to bear interest at the Federal Funds Rate or Base Rate, by 1:00 p.m. (New
York City, New York time) on the Funding Date or if the Cash Advance is to bear
interest at the LIBOR Rate by 1:00 p.m. (New York City, New York time) two (2)
Business Days prior to the desired Funding Date which telephonic notice shall
be confirmed by delivery of the original, or a telecopy, of a Notice of
Borrowing to the Lender by 1:00 p.m. (New York City, New York time) on the same
date of such telephonic notice in compliance with subparagraph (a) above.

If the conditions precedent set forth in this Agreement are satisfied, the
Lender shall disburse the proceeds of the Cash Advance to the Borrower on such
Funding Date in accordance with the Borrower's disbursement instructions set
forth in the applicable Notice of Borrowing.

         2.4     INTEREST RATE.

                 (a)      The outstanding principal balance of the Loan shall
bear interest from the date funded until paid, except as otherwise provided in
subsections (b) and (c) below, at a rate per annum equal to the lesser of (x)
the Legal Maximum or (y) the rate for each Tranche determined according to the
following:

                          (i)     for the Base Rate Tranche, a fluctuating rate
per annum equal to the sum of the Base Rate plus the appropriate Margin

         no later than the last
         Business Day occurring
         before the Expiration Date.
</TABLE>

                 (b)      If, at any time with respect to a Base Rate Tranche
or during the Interest Periods of a Federal Funds Tranche or a LIBOR Tranche,
the interest rate then in effect with respect to such Tranche or Tranches,
would exceed the Legal Maximum the Lender could charge, then, notwithstanding
the other provisions hereof and the Borrower's election, the interest rate
chargeable with respect to such affected Tranche or Tranches shall immediately
become the Legal Maximum, provided that such affected Tranche or Tranches shall
thereafter accrue interest at the Legal Maximum until such time as the Lender
has received a sum equal to the amount of interest which would have accrued on
such affected Tranche or Tranches had such Tranche or Tranches accrued interest
at the interest rate otherwise applicable thereto.  So long as interest is
calculated pursuant to this provision, the Borrower is not entitled to elect
that any Tranche be issued, renewed or converted to, a LIBOR Tranche, and the
interest rate for a Base Rate Tranche or a Federal Funds Tranche shall not be
reinstated.

                 (c)      After the occurrence of an Event of Default, the Loan
shall bear interest at the Default Rate.

                 (d)      If the total amount of interest paid or accrued,
together with any other fees payable pursuant to this Agreement and the other
Loan Documents which are deemed to be interest under applicable law with
respect to a Lender pursuant to this Agreement and the other Loan Documents, is
less than the total amount of interest which would have been paid or accrued if
the varying rates per annum equal to the interest provided pursuant to Section
2.4(a)(y) had at all times been in effect and all fees provided for





REVOLVING CREDIT AGREEMENT, PAGE 6
<PAGE>   12
in this Agreement and the other Loan Documents had been paid, then the Borrower
agrees to pay to the Lender, upon demand, an amount equal to the excess of (i)
the lesser of (A) the amount of interest and fees which would have accrued if
the Highest Lawful Rate had at all times been in effect, or (B) the amount of
interest and fees which would have accrued if a varying rate per annum equal to
the interest provided pursuant to Section 2.4(a)(y) had at all times been in
effect and all fees provided for in this Agreement and the other Loan Documents
had been paid, over (ii) the amount of interest and fees paid in accordance
with the other provisions of this Agreement and the other Loan Documents.

         2.5     COMPUTATION OF INTEREST.  Interest on all Obligations shall be
computed on the basis of the actual number of days elapsed in the period during
which interest accrues and on the basis of a year of 360 days, unless such
computation would cause the effective interest rate to exceed the Legal
Maximum, in which event such computation shall be on the basis of a year of 365
or 366 days, as the case may be.  In computing interest on any Advance, the
date of the funding of the Advance shall be included, and the date of payment
shall be excluded; provided, however, if an Advance is repaid on the same day
on which it is made, one (1) day's interest shall be paid on such Advance.

         2.6     PAYMENTS.

                 (a)      The outstanding unpaid principal of the Obligations,
including, without limitation, the Loan, shall be paid in full on the
Expiration Date or such earlier date on which the Obligations have been
declared due and payable in accordance with the terms hereof.

                 (b)      Interest is due and payable on each Interest Payment
Date applicable to each Tranche.

                 (c)      Each payment under this Agreement shall be made at
the principal office of the Lender at New York City, New York, in funds
available for immediate use not later than 1:00 p.m. (New York City, New York
time) the day the payment is due, and any payment made after such time shall be
deemed made on the next Business Day.  All payments and all proceeds of
Collateral shall be applied by the Lender to the Obligations in such order as
the Lender may determine.

                 (d)      When any payment to be made by the Borrower hereunder
or under the Note is stated to be due on a day which is not a Business Day, the
payment shall, except as may otherwise be provided herein, instead be due on
the next succeeding Business Day, and any such extension of time shall be
included in the computation of the payment of interest and fees hereunder.

                 (e)       Any prepayment shall be accompanied by the payment
of the interest accrued on the principal amount so prepaid.





REVOLVING CREDIT AGREEMENT, PAGE 7
<PAGE>   13
Prepayments of principal shall be applied first to the Base Rate Tranche and
then to the Federal Funds Tranche and then to the LIBOR Tranches selected by
the Borrower, provided that the Borrower shall select such LIBOR Tranches as
will minimize the Consequential Loss resulting from such payment; provided
further that if a Default exists or if the Borrower fails to select the
Tranches to be prepaid, the Lender may select such Tranches.

                 (f)      All payments (whether of principal, interest, fees,
reimbursements, or otherwise) by the Borrower under this Agreement shall be
made without adjustment, setoff, or counterclaim and shall be made free and
clear of and without deduction for any present or future tax, or any other
charge, if any, of any nature whatsoever now or hereafter imposed by any
Governmental Authority (excluding herefrom with respect to the Lender any such
tax or other charge imposed on or measured by its net income and any capital
and franchise taxes imposed on it by the USA, the Governmental Authorities of
the applicable Lending Office, and the Governmental Authorities in which it is
organized).  If the making of such payment by the Borrower is prohibited by law
unless such a tax, or other charge is deducted or withheld therefrom, the
Borrower shall to the extent permitted by applicable law pay on the date of
each such payment, such additional amounts (without duplication of any amounts
required to be paid pursuant to the provisions hereof regarding capital
adequacy) as may be necessary in order that the net amounts received by such
Person after such deduction or withholding equal the amounts which would have
been received if such deduction or withholding were not required.  The Borrower
shall make the required deduction and shall confirm that all applicable taxes,
if any, imposed on this Agreement or transactions hereunder shall have been
properly and legally paid by it to the appropriate tribunal by sending official
tax receipts or notarized copies of such receipts to the Lender within thirty
(30) days after payment of any applicable tax.

         2.7     LETTER OF CREDIT (STANDBY ONLY) SUBFACILITY.

                 (a)      Subject to the terms and conditions set forth in this
Agreement, the Lender agrees to issue one or more Letters of Credit for the
account of the Borrower.  The Lender has no obligation to issue any Letter of
Credit if any of the following facts or circumstances exist:

                          (i)     the aggregate amount of the Letter of Credit
Obligations, after giving effect to the issuance of the Letter of Credit
requested, would exceed any limit imposed by law or regulation upon the Lender;

                          (ii)    on the date of the proposed issuance of such
Letter of Credit (A) immediately after giving effect to the issuance of such
Letter of Credit, the Revolving Credit Obligations at such time would exceed
the lesser of the Borrowing Base or the Commitment at such time, or (B) one or
more of the conditions





REVOLVING CREDIT AGREEMENT, PAGE 8
<PAGE>   14
precedent contained herein, as applicable, would not on such date be satisfied;

                     (iii)        the requested Letter of Credit would have an
expiration date later than the Business Day immediately preceding the
Expiration Date; provided, however, if, at the request of the Borrower, the
Lender, in its sole discretion, chooses to issue (although not obligated to do
so), a Letter of Credit with an expiration date after such date above, the
Borrower agrees that on the date of issuance, but prior to issuance, it shall
deposit Cash Collateral with the Lender in an amount equal to the face amount
of such Letter of Credit but if such Cash Collateral is not timely delivered to
Lender, Lender shall not issue such Letter of Credit;

                     (iv)   the requested Letter of Credit would be in a
currency other than Dollars;

                      (v)   the Borrower has failed to execute and deliver to
the Lender any requested Letter of Credit Reimbursement Agreement and such other
documents and materials as may be required pursuant to the terms thereof;

                     (vi)   the terms of the proposed Letter of Credit are not
satisfactory to the Lender in its sole discretion; or

                    (vii)   Regardless of Borrower's compliance with each of the
other conditions herein to the issuance of a Letter of Credit, Lender, in its
sole discretion, chooses to not issue any Letter of Credit.

                 (b)      The Borrower shall not request and may not obtain a
Letter of Credit except for use in connection with transactions entered into by
it in the ordinary course of business.

                 (c)      The Borrower shall give the Lender irrevocable
written notice that it desires the Lender to issue a Letter of Credit not later
than 3:00 p.m. (New York City, New York time) two (2) Business Days preceding
the requested date for issuance thereof, or such shorter notice as may be
acceptable to the Lender.  The notice shall specify the stated face amount of
the Letter of Credit requested, the requested date (which shall be a Business
Day) of issuance of such Letter of Credit, the date on which such Letter of
Credit is to expire, the Person for whose benefit such Letter of Credit is to
be issued, the conditions for the beneficiary's making a drawing thereunder,
any other relevant terms of such Letter of Credit, and the amount of the then
outstanding Letter of Credit Obligations, Revolving Credit Obligations and the
amount of the Borrowing Base as reflected in the most recently dated Borrowing
Base Certificate provided to Lender in accordance with the provisions hereof.

                 (d)      (i)     The Lender shall give the Borrower written
notice, or telephonic notice confirmed promptly thereafter in





REVOLVING CREDIT AGREEMENT, PAGE 9
<PAGE>   15
writing, of all drawings under a Letter of Credit and of the anticipated
Reimbursement Date.  The Borrower shall, not later than the anticipated
Reimbursement Date, reimburse the Lender for the amount of such drawing.

                     (ii)         Unless the Borrower has paid the Lender in
immediately available funds by 1:00 p.m.  (New York City, New York time) on the
anticipated Reimbursement Date as specified in the notice given pursuant to
subsection (a) hereof, the Borrower shall be deemed to have requested a Letter
of Credit Advance for such purpose (irrespective of the satisfaction of any
conditions thereto or whether any Default or Event of Default then exists).

                    (iii)         No action taken or omitted in good faith by
the Lender under or in connection with any Letter of Credit shall put the
Lender under any resulting liability to the Borrower.  In determining whether
to pay under any Letter of Credit, the Lender has no obligation other than to
confirm that any documents required to be delivered under a respective Letter
of Credit appear to have been delivered and that each appears on its face to
comply with the requirements of such Letter of Credit.  The obligations of the
Borrower to make payments to the Lender with respect to a Letter of Credit are
irrevocable, are not subject to any qualification or exception whatsoever
except willful misconduct or gross negligence of the Lender, and shall be
honored under all circumstances, including without limitation (A) any lack of
validity or enforceability of this Agreement or any of the other Loan
Documents; (B) the existence of any claim, setoff, defense or other right which
the Borrower may have at any time against a beneficiary of a Letter of Credit
or any transferee of a beneficiary of a Letter of Credit (or any Person for
whom any such transferee may be acting), the Lender, or any other Person,
whether in connection with this Agreement, any Letter of Credit, the
transactions contemplated herein or any unrelated transactions (including any
underlying transactions between the account party and beneficiary named in any
Letter of Credit); (C) the inaccuracy of any statement in or forgery, fraud,
invalidity, or insufficiency in any respect of any draft, certificate, or any
other document presented under the Letter of Credit; or (D) the surrender or
impairment of any security for the performance or observance of any of the
terms of any of the Loan Documents.

                     (iv)         The Borrower agrees to release each
Indemnitee and to defend, indemnify, and save each Indemnitee harmless from and
against any claim, liability, loss, cost, or expense (including reasonable
attorneys' fees but excluding taxes) which the indemnified Person may incur or
be subject to directly or indirectly arising out of or in any manner related to
the issuance of any Letter of Credit, the honoring of or failure to honor any
drawing under any Letter of Credit except only such claims, liabilities,
losses, costs, and expenses of any Indemnitee caused by the gross negligence or
willful misconduct of such Indemnitee.  THE BORROWER INTENDS TO RELEASE AND
INDEMNIFY EACH INDEMNITEE FROM





REVOLVING CREDIT AGREEMENT, PAGE 10
<PAGE>   16
THE CONSEQUENCES OF ITS OWN SOLE, CONCURRENT, OR CONTRIBUTORY NEGLIGENCE,
provided that this subsection shall not require the Borrower to indemnify the
Lender for any damages in addition to the amount of a drawing which are
incurred by the Lender as a result of its failure to honor a drawing strictly
complying with the terms of the Letter of Credit.

                 (v)      The Borrower assumes all risks of the acts and
omissions of, or misuse of Letters of Credit, by the beneficiaries of the
Letters of Credit.  The Lender is not responsible for, nor is the Borrower's
liability with respect thereto subject to reduction by reason of (A) the form,
validity, legality, sufficiency, accuracy, genuineness or legal effect of any
document submitted by any party in connection with the application for and
issuance of the Letters of Credit, even if it is in any respect invalid,
insufficient, inaccurate, fraudulent or forged; (B) the validity, legality or
sufficiency of any instrument transferring or assigning or purporting to
transfer or assign a Letter of Credit or the rights or benefits thereunder or
proceeds thereof, in whole or in part, which is invalid or ineffective for any
reason; (C) the failure of the beneficiary of a Letter of Credit to comply duly
with conditions required in order to draw upon such Letter of Credit; (D)
errors, omissions, interruptions or delays in transmission or delivery of any
messages, by mail, cable, telegraph, telex or otherwise, whether or not they
are in cipher; (E) errors in interpretation of technical terms; (F) any loss or
delay in the transmission or otherwise of any document required in order to
make a drawing under any Letter of Credit or of the proceeds thereof; (G) the
misapplication by the beneficiary of a Letter of Credit of the proceeds of any
drawing under such Letter of Credit; (H) any litigation, proceeding or charges
with respect to such Letter of Credit; (I) the failure of the Lender to give
any notice under this Section; or (J) any consequences arising from causes
beyond the control of the Lender.

         2.8     LETTER OF CREDIT ISSUANCE FEE.

                          (i)     The Borrower shall pay to the Lender a fee
accruing at a per annum rate equal to one and one-half percent (1.5%) per annum
on the undrawn face amount of each outstanding Letter of Credit, payable in
advance on the date such Letter of Credit is issued; provided, however,
effective (i) immediately upon the occurrence of an Event of Default described
in SECTION 8.1(A), or (ii) retroactively to the date of an occurrence of any
other Event of Default described in SECTION 8.1 upon notice from the Lender of
the effectiveness of this Section, and for so long thereafter as such Event of
Default shall be continuing, the rate at which the Letter of Credit Fees shall
accrue and be payable shall be equal to three and one-half percent (3.5%) per
annum;

                          (ii)    Additionally, the Borrower shall pay to the
Lender the standard charges assessed by the Lender in connection with the
issuance, administration, amendment and payment or





REVOLVING CREDIT AGREEMENT, PAGE 11
<PAGE>   17
cancellation of Letters of Credit and such compensation in respect of such
Letters of Credit for the Borrower's account as may be agreed upon by the
Borrower and the Lender from time to time, and further Borrower shall pay any
and all other costs and out-of-pocket expenses incurred by Lender at any time
related to or resulting from Borrower's request to issue a Letter of Credit or
the issuance of such.

         2.9     VOLUNTARY REDUCTION OF COMMITMENT.  The Borrower may from time
to time and subject to any other limitations in this Agreement on at least two
(2) Business Days' prior written irrevocable notice received by the Lender
permanently reduce the aggregate amount of the Commitment hereunder, but only
upon making a payment of the accrued but unpaid amount of the Commitment Fee to
the date of reduction and any other payment required by the terms of this
Agreement.  Any partial reduction will be in an aggregate amount of ONE MILLION
DOLLARS ($1,000,000) or an integral multiple thereof.  The Commitment Fee
provided for herein will not thereafter be due with respect to the amount by
which the Commitment was reduced.  The Borrower may at any time on like notice
terminate the Commitment upon payment in full of the Obligations.

         2.10    AMOUNTS EXCEEDING LIMITS.  If the Revolving Credit Obligations
at any time exceeds the lesser of the Borrowing Base or the Commitment, the
Borrower will within five (5) Business Days of any such determination (a) pay
in cash to the Lender at its office in New York City, New York, the amount of
such excess, such payment first to be applied to Reimbursement Obligations and
next to the Loan, and the balance, if any, to be held by the Lender as Cash
Collateral; or (b) deliver to Lender, at its office in New York City, New York,
additional collateral, which shall be in form and content and value
satisfactory to Lender to equal in aggregate value the amount of such excess,
in Lender's sole discretion; or (c) deliver to Lender, at its office in New
York City, New York, a combination of cash and such additional collateral which
in aggregate value shall equal the amount of such excess, in Lender's sole
opinion.

         2.11    COMMITMENT FEE.  For the period commencing on the Closing Date
and ending on the Expiration Date, the Borrower shall pay to the Lender a fee
accruing at the rate of 0.25% per annum on the average daily amount during each
fiscal quarter by which the Commitment exceeds (i) the Loan, plus (ii) the
aggregate undrawn face amount of all outstanding Letters of Credit.  The
Commitment Fee is payable quarterly, in arrears, commencing on the last day of
the fiscal quarter next succeeding the Closing Date and on the last day of each
fiscal quarter thereafter, and on the Expiration Date.

         2.12    CALCULATION AND PAYMENT OF FEES.  The fees required to be paid
under Section 2.11 shall be calculated on the basis of the actual number of
days elapsed but a 360-day year.  All such fees are payable in addition to, and
not in lieu of, principal, interest, expense reimbursements, indemnification
and other





REVOLVING CREDIT AGREEMENT, PAGE 12
<PAGE>   18
Obligations.  Fees shall be payable in accordance with SECTION 2.6.  All fees
shall be fully earned and non-refundable when paid.  All fees specified or
referred to in this Agreement due to the Lender shall bear interest, if not
paid when due, at the Default Rate, shall constitute Obligations, and shall be
secured by the Collateral.

         2.13    EXPIRATION.  The Commitment shall terminate on the Expiration
Date or such earlier date on which the Commitment is terminated in accordance
with the terms hereof.  However, if prior to December 1, 1997 the Commitment
has not been otherwise terminated, Lender, in its sole discretion, will
consider extending the Expiration Date for a one (1) year period but Lender
does not have any obligation to do such and if Lender has not agreed in writing
to do so under terms and conditions satisfactory to Lender prior to December 1,
1997 and the Commitment has not been otherwise terminated, the Commitment will
terminate on December 1, 1997.

         2.14    PAYMENT OF FUNDING LOSSES.

                 (a)      The Borrower shall indemnify the Lender against any
loss or expense incurred by it as a result of any failure by the Borrower to
fulfill, on or before the date specified for any Advance or renewal or
conversion of the interest rate applicable to any Tranche, the conditions
thereof, including, without limitation, any loss (including loss of anticipated
profits) or expense incurred by reason of the liquidation or re-employment of
deposits or other funds when such Advance or renewal or conversion of the
interest rate applicable to any Tranche is not made on such date as a result of
such failure.  A certificate in reasonable detail as to the amount of any such
loss or expense submitted to the Borrower shall be conclusive as to the amount
thereof except in cases of manifest error.  A copy of any such statement
submitted by the Lender shall be given to the Lender.

                 (b)      If for any reason, including without limitation
because any prepayment is required by reason of a reduction in the Commitment
or because the Revolving Credit Obligations exceed at any time the lesser of
the Borrowing Base or the Commitment, the Lender receives all or part of its
portion of the principal amount of a Tranche prior to the last day of the
Interest Period applicable thereto, the Borrower shall pay the Lender the
amount (if any) of the Consequential Loss occasioned by such payment.  A
certificate of such Lender submitted to the Borrower shall be conclusive absent
manifest error.

         2.15    CAPITAL ADEQUACY AND INCREASED COSTS.

                 (a)      If after the date hereof (i) the adoption or
implementation, change, or phasing in of any law or regulation or in the
interpretation thereof by any domestic or foreign Governmental Authority
charged with the administration thereof or (ii) compliance with any directive,
guideline or request from any





REVOLVING CREDIT AGREEMENT, PAGE 13
<PAGE>   19
central bank or domestic or foreign Governmental Authority (whether or not
having the force of law) promulgated or made after the date hereof affects or
would affect the amount of capital required or expected to be maintained by the
Lender or any corporation directly or indirectly controlling the Lender has or
would have the effect of reducing the rate of return on such capital or the
asset value of any Advance made or Letter of Credit issued hereunder to a level
below that which the Lender or such controlling corporation could have achieved
but for such adoption, implementation, change, phasing in, or compliance (after
taking into account the Lender's or such corporation's policies regarding
capital adequacy) by an amount deemed by the Lender to be material to the
Lender or such corporation, then, within ten (10) days after written demand by
the Lender (accompanied by a statement of the type referred to below, the
Borrower shall pay to the Lender such additional amount or amounts as shall be
sufficient to compensate the Lender or such controlling corporation for any
such reduction.

                 (b)      If any law, regulation, treaty, or directive
hereafter enacted, promulgated, approved, or issued or any change in any
presently existing law, regulation, treaty, or directive therein or in the
interpretation or application thereof by any Governmental Authority charged
with the administration thereof (whether or not having the force of law) or
compliance by the Lender or any corporation directly or indirectly owning or
controlling the Lender (in each case, the "Affected Person") with any request
or directive from any central bank or other Governmental Authority, agency, or
instrumentality

                          (i)     subjects such Affected Person to any tax,
duty, or other charge of any kind whatsoever with respect to its Commitment,
any Advance, or its obligations under this Agreement to make Advances, or issue
Letters of Credit or any amounts payable to it hereunder (and any additional
income or franchise taxes resulting therefrom), or changes the basis of
taxation of payments to such Affected Person of principal, interest, or any
other amount payable hereunder in respect of the Loan or any Letter of Credit
(except for imposition of, or change in the rate of, any tax (A) on the overall
net income of such Affected Person or direct substitute for such tax, or (B)
which would not have been imposed if such Affected Person complied with any
certification, information, documentation or other reporting requirement); or

                     (ii)         imposes, modifies, or makes applicable any
reserve, special deposit, compulsory loan, assessment, increased cost, or
similar requirement against assets held by, or deposits of, or advances or
loans or letters of credit by, or other credit extended by, or any other
acquisition of funds by, any office of such Affected Person in respect of the
Loan or any Letter of Credit which is not otherwise expressly included in the
determination of the applicable rate or rates of interest hereunder,





REVOLVING CREDIT AGREEMENT, PAGE 14
<PAGE>   20
and the result of any of the foregoing is to increase the cost of making,
renewing, or maintaining the Loan or issuing Letters of Credit or the
commitment to make Advances or to reduce any amount receivable by the Lender
hereunder in respect of any of the foregoing then, in any such case, the
Borrower shall promptly pay the Lender upon demand any additional amounts
necessary to compensate the Lender for such additional cost (including any
penalties, interest, and out-of-pocket expenses paid to third parties, but
excluding any late payment penalties which resulted solely from the Lender's
inaction in seeking indemnification hereunder) or reduction in such amount
receivable.

                 (c)      The Lender will, if possible, designate a different
Lending Office if such will avoid the need for, or reduce the amount of, any
compensation hereunder and is not otherwise disadvantageous to the Lender.
This Section shall apply and the Lender is entitled to payment hereunder,
notwithstanding any possible invalidity or inapplicability of any event or
provision which may require payment hereunder.  A statement setting forth the
calculations of any additional amounts payable submitted by the Lender to the
Borrower shall be conclusive absent manifest error.  No delay by the Lender in
demanding the payment of any additional amounts pursuant to this Section shall
constitute a waiver of its right to demand payment of such amounts at any
subsequent time.  In determining the additional amount payable pursuant to this
Section, the Lender shall take into account any transitional adjustment or
phase-in provisions of such reserve requirements which would reduce the reserve
requirement otherwise applicable; provided, however, the Lender, in its sole
discretion, may determine the allocation of reserve requirements.  Each such
determination made by the Lender, and each notification to the Borrower under
this Section, shall be presumptive as to the matters therein set forth in the
absence of manifest error in calculation.  The Lender agrees to provide on
request by the Borrower such certificates as are reasonably required, and take
such other actions as are reasonably necessary to claim such exemptions as the
Lender may be entitled to claim in respect of all or a portion of any sums
which are otherwise required to be paid or deducted or withheld pursuant to
this Section.  This Section shall not be construed, nor shall it operate, to
require the Borrower to pay any sums not permitted or in excess of the limits
imposed by applicable law.

         2.16    CHANGE IN CIRCUMSTANCES.

                 (a)      If with respect to any Federal Funds Tranche the
Lender determines (which determination shall be in good faith and shall be
conclusive and binding upon the Borrower) that no timely quotations of the
applicable rate offered in the interbank federal funds market in New York City,
New York or other sources available to the Lender as contemplated in the
definition of "Federal Funds Rate" herein or the Lender determines (which
determination shall be in good faith and shall be conclusive and binding upon
the Borrower) that by reason of circumstances affecting the market for





REVOLVING CREDIT AGREEMENT, PAGE 15
<PAGE>   21
federal funds, fair and adequate means do not exist for determining the Federal
Funds Rate or the Federal Funds Rate does not adequately reflect the cost of
funds to the Lender, the Lender may give notice thereof to the Borrower, and
such determination shall be conclusive and binding on the Borrower.  After such
notice has been given and until the Lender notifies the Borrower that the
circumstances giving rise to such notice no longer exist, the obligation to
permit a Federal Funds Rate election shall be suspended, and Federal Funds
Tranches shall be converted on the last day of the then-current applicable
Interest Period to a Base Rate Tranche unless the Borrower elects the LIBOR
Rate in accordance with the terms hereof.

                 (b)      If the Lender determines (which determination shall
be made in good faith and shall be conclusive and binding upon the Borrower)
that (i) adequate and reasonable means do not or will not exist for
ascertaining the interest rate applicable to any LIBOR Tranche, (ii) Dollar
deposits in the relevant amounts and for the relevant Interest Period are not
available to the Lender in the LIBOR Market, or (iii) the LIBOR Rate does not
accurately reflect the cost of funds to the Lender, then the Lender shall
forthwith give notice of such determination to the Borrower, whereupon, until
the Lender notifies the Borrower that the circumstances giving rise to such
suspension no longer exist, the obligation of the Lender to permit a LIBOR Rate
election shall be suspended and LIBOR Tranches shall be converted on the last
day of the then current applicable Interest Period to a Base Rate Tranche
unless the Borrower timely notifies the Lender that it desires that the
conversion be to a Federal Funds Tranche subject to the provisions of
subparagraph (a) above.

                 (c)      If after the date of this Agreement the introduction
of or any change in any applicable law, rule or regulation or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof or compliance by the Lender
with any request or directive (whether or not having the force of law) of any
authority makes it unlawful or not reasonably possible for the Lender (or its
Lending Office) to make, maintain or fund LIBOR Tranches, the Lender shall so
notify the Borrower.  Before giving any notice pursuant to this Section, the
Lender shall if possible designate a different Lending Office if such
designation will avoid the need for giving such notice and in the Lender's sole
judgment will not be otherwise disadvantageous to the Lender.  Upon receipt of
such notice, if the Lender has received a request with respect to the affected
type of Interest Rate Option, the Borrower shall be deemed to have designated
the Base Rate without any further notice from the Borrower.  Any Tranche
bearing interest at the affected Interest Rate Option shall immediately become
a Base Rate Tranche.  If circumstances subsequently change so that the Lender
is not further affected, the obligation to permit election of the formerly
affected Interest Rate Option shall be reinstated upon written request of the
Borrower.





REVOLVING CREDIT AGREEMENT, PAGE 16
<PAGE>   22
         2.17    LENDING OFFICE.  The Lender may without notice to or consent
from the Borrower (a) designate its principal office or a foreign branch, a
Subsidiary, or an Affiliate of the Lender as its lending office (and the office
to whose accounts payments are to be credited) for any LIBOR Tranche, (b)
designate its principal office or a domestic branch, a Subsidiary, or an
Affiliate as its lending office (and the office to whose account payments are
to be credited) for any Base Rate Tranche or Federal Funds Tranche, and (c)
change its Lending Offices from time to time by notice to the Borrower.  In
such event, the Lender shall continue to hold the Note evidencing its Advances
for the benefit and account of such foreign branch, subsidiary, or affiliate.
The Lender is entitled to fund all or any portion of the Loan in any manner
which it may determine in its sole discretion, but all calculations and
transactions hereunder shall be conducted as though the Lender has actually
funded each Tranche at its Lending Office regardless of the actual means of
funding.

         2.18    PREPAYMENTS.  The Borrower may from time to time upon two (2)
Business Days' prior written notice to the Lender (which shall specify the
amount of such prepayment and the date thereof, which shall be a Business Day)
and subject to any other limitations in this Agreement prepay the Loan in whole
or in part without penalty or premium except as may be incurred in connection
with payment of a LIBOR Tranche prior to the end of the applicable Interest
Period in accordance with SECTION 2.14 hereof, provided any partial prepayment
shall be not less than a principal amount equal to FIVE HUNDRED THOUSAND
DOLLARS ($500,000) and in integral multiples of $100,000 in excess thereof.


                                  ARTICLE III

discretion:

REVOLVING CREDIT AGREEMENT, PAGE 19
<PAGE>   25
giving effect thereto (a) no Default or Event of Default has occurred and is
continuing; (b) the representations and warranties contained herein are true
and correct in all material respects as of such date, as if then made (except

due and payable; (d) no change in the condition (financial or otherwise),
business, assets, operations, or affairs of Group or Borrower or Simply Fresh

the Letter of Credit, as the case may be, shall not constitute a waiver of the

         3.4     POST CLOSING CONDITION.  Simply Fresh will deliver to Lender

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

         To induce the Lender to enter into this Agreement and to perform its
agreements hereunder, each Obligated Party, jointly and severally, represents
and warrants that each of the following statements is correct:

         4.1     ORGANIZATION AND AUTHORITY.  Each Obligated Party is duly
organized, validly existing, and in good standing under the laws of its state
of creation and is duly qualified to do business and in good standing in every
other state in which, under presently





REVOLVING CREDIT AGREEMENT, PAGE 20
<PAGE>   26
applicable law, the nature of its property or business requires such
qualification and in which the failure to be so qualified would (when
considered alone or when aggregated with the effect of failure to qualify in
all other jurisdictions) have a Material Adverse Effect.  All of the
outstanding capital stock of each Obligated Party is duly authorized, validly
issued, fully paid, and non-assessable.  Each Obligated Party has all requisite
power and authority to conduct its business, to own, lease, operate, or
maintain its properties.  Each Obligated Party has all requisite power and
authority to execute and deliver and perform all of its obligations under the
Loan Documents.

         4.2     VALIDITY, AUTHORIZATION, AND NO CONFLICT.  The execution,
delivery, and performance by each Obligated Party of the Loan Documents to
which it is a party and the consummation of the transactions contemplated in
connection therewith (a) have been duly authorized by such Obligated Party, (b)
do not violate any provision of the Articles of Incorporation or the By-Laws of
such Obligated Party, and (c) are not prohibited by and do not violate nor
constitute a default under any law, or any presently existing requirement or
restriction imposed by any judgment, order, writ, injunction, decree, or award
of any arbitral authority or any Governmental Authority, or any agreement,
instrument, or indenture by which any Obligated Party is bound, or result in
the creation of any Lien upon any of the assets of any Obligated Party, except
for Permitted Liens.  The Loan Documents have been duly executed and delivered
by each Obligated Party thereto, and such Loan Documents are legal, valid, and
binding obligations of such Obligated Party enforceable in accordance with
their respective terms, except as the enforcement thereof may be limited by
applicable bankruptcy or debtor relief laws affecting the rights of creditors
generally and general principles of equity.

         4.3     NO PROCEEDINGS.  (a) All actions, suits, claims, or
proceedings pending or threatened against any Obligated Party or its properties
or assets before any Governmental Authority or private arbitrator are listed on
EXHIBIT 4.3.

         (b)     There are no actions, suits, claims, or proceedings pending or
threatened against any Obligated Party or its properties or assets before any
Governmental Authority, or private arbitrator which has, or if adversely
determined would have, a Material Adverse Effect on any Obligated Party or
which challenge the validity of any of the Loan Documents or any of the
transactions contemplated therein or thereby.

         4.4     NO APPROVALS.  Neither the making, execution, delivery, or
performance of any of the Loan Documents nor the consummation of the
transactions contemplated in connection therewith requires the consent or
approval of any Person or if any such approval is required, such approval has
been obtained.





REVOLVING CREDIT AGREEMENT, PAGE 21
<PAGE>   27
         4.5     NO DEFAULT.  No Default has occurred and is continuing or will
result from the making of any requested Advance or Letter of Credit.  No
Obligated Party is in default under, and no event has occurred which with the
lapse of time or giving of notice, or both, could result in a default under,
any indenture, agreement, lease, or other instrument or in violation of any
statute, regulation, judgment, injunction, decree, determination, or award the
result of which would be a Material Adverse Effect.

         4.6     ADVERSE CIRCUMSTANCES.  Neither the business nor any property
of any Obligated Party is presently affected by any fire, explosion, accident,
strike, lockout, or other dispute, embargo, act of God, act of public enemy, or
similar event or circumstances nor has any other event or circumstance relating
to its business or affairs occurred which has had or may reasonably be expected
to have a Material Adverse Effect.

         4.7     TAX RETURNS AND PAYMENTS.  All foreign, federal, state, and
other tax returns of each Obligated Party required to be filed have been filed,
and all foreign, federal, state, and other taxes, assessments, fees, and other
governmental charges (domestic and foreign) imposed on each Obligated Party
which are due and payable have been paid except for any such tax, assessment,
fee, or charge which is being contested in good faith and for which adequate
reserves satisfactory to the Lender have been established on the books of such
Obligated Party.  There is no material deficiency or assessment which may be
asserted in connection with any of said taxes, assessments, fees, or charges.

         4.8     FINANCIAL STATEMENTS.  The Borrower and Group have delivered
to the Lender its audited consolidated Financial Statements for the fiscal year
ended December 31, 1995, and the unaudited consolidated Financial Statements
for the period from January 1, 1996 through and including September 30, 1996;
such Financial Statements are complete and correct in all material respects
(subject, in the case of interim statements, to changes resulting from audits
and year end adjustments) and fairly present, in accordance  with GAAP, the
consolidated financial condition of the Borrower and its Subsidiaries as of the
dates thereof and for the periods then ended.  The statements of income and
cash flow fairly present the results of the consolidated operations of the
Group and its Subsidiaries for the periods indicated.  Since said dates there
has been no material adverse change in such financial condition, and except as
reflected or referred to in any said Financial Statements, there are no
contingent or disputed liabilities or unrealized or anticipated losses which in
the aggregate are material.

         4.9     PURPOSE.  No Obligated Party is engaged in the business of
extending credit for the purpose of purchasing or carrying "margin stock"
(within the meaning of Regulation G, T, U, or X promulgated by the Board and in
effect from time to time), and the making of the loans and the execution,
delivery, and performance of





REVOLVING CREDIT AGREEMENT, PAGE 22
<PAGE>   28
the Loan Documents, and the use of the proceeds of the Advances will not
violate any of such Regulations.  The proceeds of each Advance will not be used
to acquire any security in any transaction subject to Sections 13 and 14 of the
Securities Act of 1934.

         4.10    ACCURACY OF DISCLOSURES.  All writings prepared by or on
behalf of any Obligated Party or any Subsidiary of an Obligated Party furnished
to the Lender for the benefit of, for the purposes of, or in connection with,
the Loan Documents or any transaction contemplated hereby or thereby, were true
and accurate in all material respects on the date such writings were furnished
and do not contain any untrue statement of any material fact or omit to state a
material fact necessary in order to make the statements contained therein not
misleading, and all other such writings hereafter furnished to the Lender for
the benefit of, by, or on behalf of any Obligated Party or any Subsidiary of an
Obligated Party shall be true and accurate in all material respects on the date
such writings are so furnished.  There is not to the knowledge of any Obligated
Party any fact which materially and adversely affects or in the future may (so
far as any Obligated Party can foresee) materially and adversely affect the
operations, business, assets prospects, or condition of such Obligated Party or
any Subsidiary of an Obligated Party or UniMark taken as a whole which has not
been specified herein or otherwise in writing furnished to the Lender.

         4.11    PROPERTY.  Each Obligated Party has good and marketable  title
to its properties.  The Collateral of the Obligated Parties is free and clear
of all Liens except for Permitted Liens and that lien or security interest
granted by Simply Fresh to Tokai Bank of California and referenced in SECTION
3.4, POST CLOSING CONDITION (the "TOKAI LIEN").  Each Lien securing any part of
the Obligations (whether granted by any Obligated Party or by any other Person)
is first and prior to any other Lien in the Collateral except the P.A.C.A. Lien
as same applies to perishable Collateral and the accounts receivable and other
proceeds arising therefrom and the Tokai Lien.  All property owned by or leased
to any Obligated Party is in adequate operating condition and repair and free
from any known defects which substantially interfere with the use thereof.
Group, Borrower, and Simply Fresh and UniMark taken as a whole has obtained and
maintains in full force and effect all rights, franchises, easements, patents,
licenses, permits, governmental approvals, and consents necessary to the
conduct of its business and affairs except where the failure to do so does not
and is not reasonably expected to have a Material Adverse Effect.

         4.12    CHIEF EXECUTIVE OFFICE.  The Borrower's chief executive office
is located at 124 McMakin Road, City of Bartonville, County of Denton, Texas,
76226 and all its principal books and records and those of each other Obligated
Party are maintained at such address.





REVOLVING CREDIT AGREEMENT, PAGE 23

has not directly or indirectly declared, ordered, paid, or set aside any
property for any Restricted Payment.

         4.14    AFFILIATES.  EXHIBIT 4.14 attached hereto contains a complete
list of the legal name of each Affiliate of each Obligated Party, the nation
and state of such Affiliate's organization, the states in which each of such
Affiliates is qualified to transact business as a foreign corporation, the
authorized, issued, and outstanding equity interests in each such Affiliate and
the relationship to any Obligated Party.

benefits to employees of each Obligated Party.

         4.18    ENVIRONMENTAL, HEALTH AND SAFETY MATTERS.  Except as disclosed
on EXHIBIT 4.18

                 (a)      the operations of each Obligated Party and UniMark

and safety permits, registrations, approvals, licenses, and authorizations

in effect as of the date hereof;

                 (c)      no Obligated Party nor UniMark taken as a whole nor

associated with such property or activity;

                 (e)      no Obligated Party has sent or arranged for the

Comprehensive Environmental Response Compensation Liability Information System
List ("CERCLIS"), or any similar state list; and

                 (f)      no present or past property of any Obligated Party is
listed or proposed for listing on the NPL pursuant to CERCLA or on the CERCLIS
or any similar state list of sites requiring response or remedial action, nor

qualify such property for inclusion on any such list.

for any required amendments for which the "remedial amendment period," as

REVOLVING CREDIT AGREEMENT, PAGE 25
<PAGE>   31
of the IRC, has not yet expired; each Employee Benefit Plan that is intended to
be qualified under Section 401(a) of the IRC has been determined by the IRS to
be so qualified, and each trust related to such plan has been determined to be
exempt under Section 501(a) of the IRC; no material liability has been incurred
by any Obligated Party or any ERISA Affiliate which remains unsatisfied for any
taxes or penalties with respect to any Employee Benefit Plan or any

                 (c)      each Obligated Party and each ERISA Affiliate has
fulfilled its obligations under the minimum funding standards of ERISA and the
IRC with respect to each Employee Benefit Plan and is in compliance in all
material respects with the presently applicable provisions of ERISA and the IRC
and has not incurred any liability to the PBGC or an Employee Benefit Plan
under Title III of ERISA.

         4.20    STATUS UNDER CERTAIN STATUTES OF USA.  No Obligated Party is
subject to regulation under the Public Utility Holding Company Act of 1935, the
Federal Power Act, the Interstate Commerce Act, or the Investment Company Act
of 1940, or any other federal or state statute or regulation which limits its
ability to incur Debt or its ability to consummate the transactions
contemplated by or in connection with the Loan Documents.

         4.21    INSIDER.  The Borrower is not, and no Person having "control"
(as that term is defined in 12 U.S.C.  Section  375b(9)(B) or in regulations
promulgated pursuant thereto) of the Borrower is, an "executive officer,"
"director," or to the knowledge of Borrower, "principal shareholder" (as those
terms are defined in 12 U.S.C. Section
 375b or in regulations promulgated pursuant thereto) of the Lender, of a bank
holding company of which the Lender is a subsidiary, or of any subsidiary of a
bank holding company of which the Lender is a subsidiary, or of any bank at
which the Lender maintains a "correspondent account" (as that term is defined
in such statute or regulations), or of any bank which maintains a correspondent
account with the Lender.

         4.22    SOLVENCY.  After giving effect to the transactions
contemplated in the Loan Documents and the Advances to be made and the Letters
of Credit to be issued on the Closing Date or such other date as Advances or
Letters of Credit requested hereunder are made or issued and the disbursement
of the proceeds of such Advances pursuant to the Borrower's instructions, and
after giving effect to the existing transactions directly between Lender and
ICMOSA and GISE which transactions are separate and apart from the transactions
contemplated in the Loan Documents, and possible future direct indebtedness
between Lender and ICMOSA and GISE, and considering that Group and all of its
Subsidiaries operate as a single consolidated entity and enterprise and as such
have capital sufficient to carry on their businesses and transactions as they
now exist and are planned in the future, each Obligated Party and UniMark taken
as a whole is Solvent.





REVOLVING CREDIT AGREEMENT, PAGE 26
<PAGE>   32
         Further, the Obligated Parties have previously represented to Lender,
and the Obligated Parties do hereby jointly and severally, represent and
warrant to Lender that Group and all of its Subsidiaries operate as a
consolidated enterprise and acknowledge and agree that Lender did rely upon the
consolidated assets of UniMark taken as a whole in determining whether to enter
into this Agreement.

         4.23    FOREIGN ASSET CONTROL REGULATIONS, ETC.  Neither the issue of
the Revolving Note by the Borrower nor the use of the proceeds thereof or of
any Letter of Credit contemplated by this Agreement or the performance of any
Obligation or covenant set forth in a Loan Document will violate the Export
Administration Act, the Foreign Corrupt Practices Act of 1977, the Foreign
Assets Control Regulations, the Transaction Control Regulations, the Cuban
Assets Control Regulations, the Foreign Funds Control Regulations, the
Nicaragua Trade Control Regulations, or the Panamanian Transactions Regulations
of the United States Treasury Department (31 C.F.F., Subtitle B, Chapter V, as
amended).

         4.24    TRADEMARKS, COPYRIGHTS, PATENTS, AND LOGOS.  EXHIBIT 4.24
contains a list of (i) all trademarks, service marks, tradenames, trade dress
and logos used by the Obligated Parties, specifically identifying each
registration, if any, of each trademark, service mark, tradename, trade dress
and logo by registration number and date and the entity issuing the
registration, and which of the Obligated Parties is an owner, licensor,
licensee, sublicensee, assignor, or assignee of the same; (ii) all copyrights,
whether registered or unregistered, owned, licensed, or leased by an Obligated
Party, including, without limitation, any copyrights registered in the United
States Copyright Office, identified by registration number, and all
applications for registration thereof, and which of the Obligated Parties is an
owner, licensor, licensee, sublicensee, assignor, or assignee of the same; and
(iii) all foreign and United States letters patent and applications for letters
patent, identified by patent or application number, owned, licensed to or from,
or otherwise acquired by an Obligated Party, and which of the Obligated Parties
is an owner, licensor, licensee, sublicensee, assignor, or assignee of the
same.

         4.25    EXISTING INDEBTEDNESS.  Except as listed on EXHIBIT 4.25, no
Obligated Party is liable for, owes or is obligated for any indebtedness
(direct, indirect or contingent).

         4.26    REAL ESTATE AND INVENTORY LOCATIONS.  Except as listed on
EXHIBIT 4.26(A), no Obligated Party owns, leases or has any interest in
(directly or indirectly) any real estate or leasehold.

         Except as listed on EXHIBIT 4.26(B), no Obligated Party stores, keeps,
or maintains its Inventory in any location (owned, leased or rented, or
provided gratuitously or as a part of a supply agreement or arrangement).





REVOLVING CREDIT AGREEMENT, PAGE 27
<PAGE>   33
         However, the only Inventory of any Obligated Party that will be
included in the Borrowing Base will be that Inventory stored by an Obligated
Party at those locations listed on EXHIBIT 4.26(C).  If the Borrower or any
other Obligated Party desires to have Inventory included in the Borrowing Base
which is stored at a location other than those listed on EXHIBIT 4.26(C) which
are known herein as the "PRIMARY INVENTORY LOCATIONS"), such Obligated Party
will deliver to Lender (i) a landlord's waiver satisfactory to Lender in form
and content to Lender and executed by said Obligated Party and the landlord or
owner of the location where such Inventory is stored (which location is listed
on EXHIBIT 4.26(B) and any other documents that Lender may reasonably request
to make such location a Primary Inventory Location, including, without
limitation, a UCC-1 Financing Statement to be filed generally at such location.

         4.27    PERISHABLE AGRICULTURAL COMMODITIES ACT.  No Obligated Party
is in violation of the Perishable Agricultural Commodities Act of 1930 (which
is set forth at 7 U.S.C. Section  499A) or any regulation related thereto
issued by the Secretary of Agricultural of the USA or any other Governmental
Authority, in part or in whole.

                                   ARTICLE V
                             AFFIRMATIVE COVENANTS

         So long as any Commitment is outstanding, any part of the Obligations
remains unpaid, or any contingent part of the Obligations continues to exist,
or until the Lender consents to the contrary and the Borrower receives prior
written approval to the contrary from the Lender, each Obligated Party, as
applicable, will comply, or cause compliance, with each of the following
covenants:

         5.1     PAYMENT OF THE OBLIGATIONS.  The Borrower will pay each part

                 (j)      a money judgment in the case of any single judgment
in the amount of $1,000,000 or more or in the case of all such judgments at any
time existing in the aggregate amount of $1,000,000 or more is entered against
any Obligated Party which is not satisfied or enforcement thereof stayed by the
first to occur of the thirtieth (30th) day after the date of the judgment or
the tenth (10th) day before the date on which assets of such Obligated Party
may be lawfully sold to satisfy such judgment;

                 (k)      a default or event of default under any instrument
evidencing Debt (other than the Obligations) of any Obligated Party occurs, the
effect of which is to permit the holder of such instrument to accelerate the
maturity thereof or require the prepayment, purchase, or redemption thereof, or
any Obligated Party fails to pay any Debt when due or the holder accelerates
the maturity of or exercises any right to require purchase or redemption of any
promissory note or other obligation or evidence of such Debt or indebtedness
which respectively such Obligated Party is obligated to pay, or an event of
default occurs under the terms of any one or more of the documents related to
the Permitted Liens or related to any material operating lease;

                 (l)      any Lien not a Permitted Lien under this Agreement
against the Collateral is filed or attaches and is not discharged, or suitable
bond is not made to prevent the enforcement thereof to the Lender's
satisfaction, within ten (10) days of the date any Obligated Party learns of
the existence thereof; and

                 (m)      the occurrence of a default or event of default under
any instrument or document evidencing, securing or guaranteeing a debt owed by
ICMOSA to the Lender.

         8.2     MATURITY OF OBLIGATIONS AND OTHER RIGHTS.

                 (a)      Upon the occurrence of an Event of Default specified
in SECTIONS 8.1(H) OR (I), and without the necessity of any action, notice, or
demand by the Lender, the Commitment shall automatically terminate and the
unpaid principal and accrued interest and fees constituting part of the
Obligations, together with all other outstanding Obligations, shall be
immediately due and payable.  Upon the occurrence of any Event of Default other
than one specified in SECTIONS 8.1(H) OR (I), the Lender by written notice to
the Borrower may do any one or more of the following: (i) terminate all or any
portion of the Commitment, whereupon the Commitment (or the terminated portion
thereof) and obligation of the Lender to make Advances and to issue any Letters
of Credit shall terminate; (ii) declare the unpaid principal and accrued
interest and fees constituting part of the Obligations, together





REVOLVING CREDIT AGREEMENT, PAGE 39
<PAGE>   45
with all other outstanding Obligations, immediately due and payable; (iii)
reduce any claim to judgment; or (iv) enforce any of the rights of the Lender
under any of the Loan Documents or otherwise provided by applicable law or
agreement.

                 (b)      Demand, presentment for payment, protest and notice
of nonpayment, or protest or dishonor, and all demands and notices of any
action taken by the Lender under this Agreement and the other Loan Documents
and notice of intent to accelerate, and notice of acceleration of, the
Obligations and any part thereof are hereby expressly waived.

         8.3     WAIVER OF RIGHTS.

                 (a)      Each Obligated Party waives (i) all benefit that
might accrue to it by virtue of any present or future law exempting the
Collateral from attachment, levy, or sale, or execution or providing for any
appraisement, valuation, stay of execution, exemption from civil process,
redemption, or extension of time for payment; (ii) any right to a marshalling
of assets or a sale in inverse order of alienation, and (iii) any right of
setoff or any claim whatsoever which may now or hereafter exist against the
Lender in its favor.

                 (b)      If any law now in force, of which any Obligated Party
or its successors might take advantage despite the provisions hereof, shall
hereafter be repealed or cease to be in force, such law shall not thereafter be
deemed to constitute any part of the contract herein contained or to preclude
the operation or application of the provisions of this Section.

                 (c)      If any payment (from any source and whether voluntary
or received from enforcement of any rights hereunder or under any other Loan
Document) is set aside, invalidated, or for any reason required to be returned
to the Person paying same, any representative of such Person, or such Person's
estate, or any receiver, custodian, trustee, or liquidator of or for such
Person, the Obligations originally intended to be satisfied shall to the extent
of such required return be reinstated and all Liens and rights and remedies
therefor shall be revived and continued in full force and effect as through
such payment had not been made.

         8.4     CROSS DEFAULT.  The occurrence of an Event of Default
hereunder constitutes a default under all other Loan Documents and other
agreements related hereto or executed in conjunction herewith.

         8.5     ENFORCEMENT OF RIGHTS.  Each Obligated Party agrees it is
commercially reasonable for the Lender to exercise its rights in or with
respect to the Collateral in such manner and in such order as the Lender
determines.  The Lender may, without foreclosing thereon, collect and otherwise
enforce all amounts owing on the Collateral or any proceeds thereof or
otherwise enforce any of the





REVOLVING CREDIT AGREEMENT, PAGE 40
<PAGE>   46
rights of such Obligated Party or the Lender therein or in any of the
Collateral and apply such collections as provided herein or may foreclose on
the Collateral.

         8.6     INJUNCTIVE RELIEF.  Each Obligated Party recognizes that if it
fails to perform, observe, or discharge any of its obligations or liabilities
under this Agreement or any other Loan Document, any remedy of law may prove to
be inadequate.  Accordingly, the Lender shall be entitled to temporary and
permanent injunctive relief in any such case.


                                   ARTICLE IX
                                 MISCELLANEOUS

         9.1     PARTICIPATIONS.  The Lender may enter into one or more
participation agreements with Persons (herein "Participants") whereby the
Lender will sell participations in the Obligations (or any part thereof) to
such Participant or Participants. Except as otherwise expressly provided or
where the context otherwise requires herein, each Participant shall be entitled
to the rights and benefits of the Lender under this Agreement as if it were
specifically named herein, and this Agreement shall be deemed to constitute a
direct obligation of the Borrower to each Participant.  The Lender shall remain
responsible for all duties of "the Lender" hereunder.  The Borrower shall not
have any duty to negotiate or confer with any Participant, and the Borrower
shall be entitled to treat the Lender as the sole owner of the Obligations,
without regard to notice or actual knowledge of any such participation
agreement.  The Borrower acknowledges that, for the convenience of all parties,
this Agreement is being entered into with the Lender only and that the
obligations under this Agreement are undertaken for the benefit of, and as an
inducement to, each of any such Participant as well as the Lender.  The
Borrower hereby grants to each such Participant, for the benefit of such
Participant, the Lender, and all other Participants, the same rights with
respect to property of the Borrower held by each such Participant as are
granted by the Borrower to the Lender in SECTION 9.2 hereof with respect to
property of the Borrower held by the Lender.  Notwithstanding the foregoing, it
is expressly understood that the maximum amount which may be recovered by the
Lender and all Participants is limited to the unpaid amount of the Obligations.
Notwithstanding the sale of any participation, the Lender shall retain the sole
right and responsibility to enforce all rights and remedies hereunder and to
approve any amendment, waiver, or other modification of any term hereof.

         9.2     RIGHTS IN PROPERTY HELD.  As additional security for the
prompt satisfaction of the Obligations and the performance of the duties of
each Obligated Party hereunder, each Obligated Party hereby collaterally
assigns and grants to the Lender a lien on and a security interest in, all
amounts that may be owing from time to time by such Person to any Obligated
Party in any capacity,





REVOLVING CREDIT AGREEMENT, PAGE 41
<PAGE>   47
including, without limitation, any balance or share belonging to any Obligated
Party, of any deposit or other account with such Person, which lien and
security interest is independent of and in addition to (a) any right of set-off
which such Person may have, and (b) the lien and security interest granted in
such property pursuant to any other Loan Document.  In addition to the
foregoing, upon the occurrence of an Event of Default, the Lender is authorized
at any time or from time to time, without notice to any Obligated Party or to
any Subsidiary of an Obligated Party or to any other Person, which notice is
hereby expressly waived, to set off and to appropriate and to apply any and all
deposits (general or special, time or demand, provisional or final, matured, or
unmatured) or any other indebtedness at any time held or owing to or for the
credit or the account of any Obligated Party against and on account of the
Obligations (without reduction by reason of the granting of any participations
in any part thereof), regardless of whether the Lender has made any demand
hereunder and although said Obligations are contingent or unmatured.

         9.3     PERFORMANCE BY THE LENDERS.  If any Obligated Party fails to
perform any covenant, duty, or agreement in accordance with the terms of the
Loan Documents, or other document relating to same, the Lender may (but in no
circumstance is obligated to), at its election but at the Borrower's expense,
perform, or attempt to perform, such covenant, duty, or agreement on behalf of
such Obligated Party in the sole discretion of the Lender.  The Lender or any
of its representatives may, in the name or on behalf of any Obligated Party or
any Subsidiary of an Obligated Party, sign, execute, or endorse the name of
such Obligated Party or Subsidiary upon, and acknowledge, witness, deliver,
file, and record, any notices, assignments, financing statements, claims,
instruments, receipts, checks, drafts, or orders and demand, sue for, collect,
or receive the Collateral or any money or property at any time payable or
receivable on account of or in exchange for, or make any compromise or
settlement deemed desirable with respect to, any of the Collateral.  Each
Obligated Party hereby appoints the Lender and its representatives as
attorney-in-fact for each Obligated Party to do any of the foregoing, and this
power, being coupled with an interest, is irrevocable so long as this Agreement
remains in effect.

         9.4     WAIVERS AND MODIFICATIONS.

                 (a)      From time to time, without notice to or further
consent by any Obligated Party, the performance or observance by any Obligated
Party of any term or provision hereof may be waived or the time of performance
thereof extended.  In addition, any Collateral therefor may be substituted,
exchanged, released, surrendered, waived, subordinated, or otherwise dealt
with, or additional Collateral obtained, all without affecting the liability of
any Obligated Party.





REVOLVING CREDIT AGREEMENT, PAGE 42
<PAGE>   48
                 (b)      No waiver or modification of any provision of this
Agreement, or consent to any departure from or supplement, amendment, or
termination of the terms hereof the other Loan Documents or any other document,
shall be effective unless such is in writing and signed by the Lender which may
be given in its sole discretion, and any such waiver shall be effective only
for the specific purpose and in the specific instance given.  No waiver of any
Event of Default shall be deemed to be a waiver of any other or subsequent
Event of Default, nor shall any waiver be deemed to be a continuing waiver.
The acceptance at any time and from time to time of partial payment of the
Obligations shall not be deemed to be a waiver of any Event of Default then
existing.  No failure, delay, or omission by the Lender in exercising any right
or power hereunder, or under any other document executed by any Obligated Party
or any Subsidiary of an Obligated Party as security for or in conjunction with
the Obligations shall impair any such right or power or be construed as a
waiver thereof or any acquiescence therein.

         9.5     CUMULATIVE RIGHTS.  All rights and remedies available to the
Lender under this Agreement are cumulative of and in addition to all other
rights and remedies available to the Lender at law or in equity, or otherwise,
and may be exercised from time to time, and as often as may be deemed
expedient, whether or not the Obligations are due and payable and whether or
not any suit for collection, foreclosure, or other action in connection with
this Agreement has been instituted, and the exercise of one or more rights or
remedies shall not impair or prejudice the concurrent or subsequent exercise of
other rights or remedies.

         9.6     CONFLICTING PROVISIONS.  The provisions of this Agreement are
in addition to those of any other Loan Document or other evidence of liability
held by the Lender and all documents shall be construed as complementary to
each other and may be enforced in accordance with their respective terms except
as hereafter provided.  Should any provision contained in any other agreement
between the Lender and Obligated Party or any Subsidiary of an Obligated Party
conflict with this Agreement, the provisions contained in this Agreement shall
control.

         9.7     SEVERABILITY.  If any provision of this Agreement or any other
Loan Document is held to be illegal, invalid, or unenforceable, such provision
shall be fully severable; the remaining provisions of this Agreement or such
other Loan Document, as appropriate, shall remain in full force and effect and
shall not be affected by such provision or by its severance.

         9.8     INDEPENDENT COVENANTS.  If any action or failure to act by any
Obligated Party violates any covenant or obligation of any Obligated Party
herein, such violation shall not be excused by the fact that such action or
failure to act would otherwise be permitted by or fall within the limitations
of any covenant (or





REVOLVING CREDIT AGREEMENT, PAGE 43
<PAGE>   49
exception to any covenant) herein contained other than the covenant violated.

         9.9     CONSTRUCTION.  Article and Section captions and the Table of
Contents are for convenience only and shall not affect the construction hereof
nor shall any provision of this Agreement be construed against any Person
solely because that Person or a representative of that Person drafted such
provision.

         9.10    SURVIVAL.  This Agreement shall terminate when (a) the
principal of and interest accrued to such date on the Loans and any outstanding
Reimbursement Obligations; (b) no Letters of Credit remain outstanding; (c) all
fees, expenses, and other amounts then due and payable which constitute
Obligations have been paid in full in cash; and (d) the Commitments have
expired or been terminated.  The termination of this Agreement shall not affect
any rights of or obligations arising prior to the effective date of such
termination nor shall it reduce or otherwise affect any release or indemnity
made herein in favor of any Indemnitee.  Notwithstanding the foregoing, if
payment hereunder must be returned for any reason, this Agreement and the other
Loan Documents shall continue in full force.  The provisions of the foregoing
sentence shall be and remain effective notwithstanding any contrary action
which may have been taken by the Lenders in reliance upon such payment, and any
such contrary action so taken shall be without prejudice to the Lenders' rights
under this Agreement and shall be deemed to have been conditioned upon such
payment having become final and irrevocable.  All covenants, agreements,
undertakings, indemnities, representations, and warranties made herein shall
survive all closings hereunder, the making of each Advance, the repayment of
the Loan, the issuance of Letters of Credit and the termination and discharge
of all other provisions of this Agreement or any of the other Loan Documents
and shall not be affected by any investigation made by any party, and all
indemnifications shall survive the repayment of the Obligations, the
termination of the Commitment, and release and termination of this Agreement.

         9.11    FORM OF DOCUMENTS.  Each agreement, document, instrument, or
other writing to be furnished to the Lender under any provision of this
Agreement must be in form and substance satisfactory to the Lender and its
counsel.

         9.12    RELIANCE ON DOCUMENTS.  Any instrument in writing, telex,
telegram, telecopy, or cable received by the Lender in connection herewith
which purports to be dispatched or signed by or on behalf of any Obligated
Party or any Subsidiary of an Obligated Party shall conclusively be deemed to
have been signed by such Person pursuant to such Person's authority to bind
such Obligated Party or a Subsidiary of an Obligated Party and all other
Persons for all liabilities in connection therewith, and the Lender may rely
thereon and shall have no duty to determine the validity or genuineness thereof
or the authority of the Person or Persons executing or dispatching the same.





REVOLVING CREDIT AGREEMENT, PAGE 44
<PAGE>   50
         9.13    COUNTERPARTS.  To facilitate execution, this Agreement and any
waiver, modification, consent, supplement, amendment, or termination hereunder
may be executed in as many counterparts as may be required.  It is not
necessary that the signature of or on behalf of each party, or that the
signatures of all persons required to bind any party, appear on each
counterpart, but it is sufficient that the signature of or on behalf of each
party, or that the signatures of the persons required to bind any party, appear
on one or more of the counterparts.  All counterparts collectively constitute a
single agreement.  It is not necessary in making proof of this Agreement to
produce or account for more than a number of counterparts containing the
respective signatures of or on behalf of all of the parties hereto.

         9.14    MAXIMUM INTEREST.  All agreements between or among each
Obligated Party and the Lender, whether now existing or hereafter arising, are
hereby limited so that in no event shall the amount paid, agreed to be paid to,
charged or demanded by the Lender for the use, forbearance, or detention of
money or for the payment or performance of any covenant or obligation contained
herein or in any other Loan Documents exceed the Legal Maximum.  If any
circumstance otherwise would cause the amount paid, charged, or demanded to
exceed the Legal Maximum, the amount paid, agreed to be paid to, charged or
demanded shall be reduced to the Legal Maximum, and if the Lender ever receives
an amount which otherwise would exceed the Legal Maximum, such amount which
would be excessive interest shall be applied to the reduction of the principal
of the Obligations and not to the payment of interest, or to the extent such
excessive amount otherwise would exceed the unpaid balance of principal of the
Obligations, such excess shall be refunded to the Borrower.  In determining
whether the interest paid, agreed to be paid, charged, or demanded hereunder
exceeds the Legal Maximum, all sums paid or agreed to be paid to, charged, or
demanded for the use, forbearance, or detention of the indebtedness of the
Borrower shall, to the extent permitted by applicable law, (i) be amortized,
prorated, allocated, and spread throughout the full term of such indebtedness
until payment in full so that the actual rate of interest on account of such
indebtedness is uniform throughout such term; (i) be characterized as a fee,
expense, or other charge other than interest; and (iii) exclude any voluntary
prepayments and the effects thereof.  The terms and provisions of this
paragraph shall control and supersede every other provision of all agreements
and communications between the Borrower or any other Obligated Party and the
Lender in conflict herewith.

         9.15    PARTIES BOUND AND ASSIGNMENT OF THE BORROWER'S INTEREST. This
Agreement shall be binding upon, inure to the benefit of, and be deemed to
include the successors and assigns of the parties hereto; provided, however,
that no Obligated Party may, without the prior written consent of all Lenders,
assign any rights, powers, duties, or obligations hereunder.





REVOLVING CREDIT AGREEMENT, PAGE 45
<PAGE>   51
         9.16    NATURE OF RELATIONSHIP; BENEFITS.  None of the terms of this
Agreement or of any Loan Document shall, or shall be deemed to, give the Lender
the right or power to exercise control over the management, conduct, or
operation of the business or affairs of any Obligated Party or any Subsidiary
of an Obligated Party or UniMark taken as a whole nor any responsibility to any
Obligated Party or any Subsidiary of an Obligated Party or UniMark taken as a
whole or any Person not a party hereto, to review, inspect, or supervise any
Obligated Party or any Subsidiary of an Obligated Party or any of the property,
business, or operations of an Obligated Party or a Subsidiary of an Obligated
Party or UniMark taken as a whole or any Collateral.  The relationship created
by this Agreement is only that of debtor and creditor, and the powers of the
Lender hereunder are limited to the right to receive payment of the Obligations
and to exercise the remedies provided herein, in the other Loan Documents and
in any other document executed in conjunction herewith or related hereto.  Any
term or condition hereof permitting the Lender to disburse funds, or to take or
refrain from taking any action with respect to any Obligated Party or any
Subsidiary of an Obligated Party or any security for the repayment of the
Obligations, may not be relied upon by any Person not a party hereto.  There
are no third party beneficiaries of this Agreement or the other Loan Documents,
and no Person other than the parties to the Loan Documents may rely thereon.

         9.17    GENERAL RELEASE AND INDEMNIFICATION BY THE OBLIGATED PARTIES.

                 (a)      In addition to any other release or indemnity herein
contained, no Indemnitee shall be liable for or with respect to, and the
Obligated Parties hereby jointly and severally indemnify and save and hold each
Indemnitee harmless from, any claim, liability, loss, cost, or expense
("CLAIMS") arising from or brought in connection with or in any manner related
to this Agreement or any of the other Loan Documents, the performance or breach
hereof or the making of any Advance, the issuance of any Letter of Credit or
the use of the proceeds of a drawing thereunder, the maintenance of the Loan,
the consummation of the transactions contemplated herein or in connection
herewith, the use of any of the proceeds of the Loan, any claimed obligation or
responsibility for the management, operation, or conduct of the business or
affairs of any Obligated Party or any Subsidiary of an Obligated Party or
UniMark taken as a whole or the payment of any debts of any Obligated Party or
any Subsidiary of an Obligated Party, or any act or omission by any Obligated
Party or any Subsidiary of an Obligated Party, whether actual or alleged,
including all costs of defense and reasonable attorney's fees.  No Indemnitee
shall be relieved of any liability arising by reason of its or their gross
negligence or willful misconduct.  If any Claims are asserted against any
Indemnitee, the Indemnitee shall endeavor to notify the Borrower of such (but
failure to do so shall not affect the indemnification herein made except to the
extent of the actual harm caused by such failure).  The Indemnitee shall have
the





REVOLVING CREDIT AGREEMENT, PAGE 46
<PAGE>   52
right to employ, at the expense of the Obligated Parties, jointly and
severally, counsel of Indemnitee's choosing and to control the defense of the
Claims.  The Borrower may at its own expense also participate in the defense of
any Claim.  Each Indemnitee may employ separate counsel in connection with a
Claim to the extent such Indemnitee believes it reasonably prudent to protect
such Indemnitee.  The obligations of the Obligated Parties under this Section
shall survive termination of this Agreement.

                 (b)      In addition to the foregoing, the Obligated Parties
shall, jointly and severally, defend, indemnify, and hold harmless each
Indemnitee from any and all liabilities (including strict liability), actions,
demands, penalties, losses, costs, or expenses (including, without limitation,
attorneys' fees and expenses, and investigatory and remedial costs), suits,
costs of any settlement or judgment, and claims of any and every kind
whatsoever which may now or in the future be paid, incurred, or suffered by or
asserted against any Indemnitee by any Person or entity or governmental agency
for, with respect to, or as a direct or indirect result of, Hazardous Materials
Contamination at, on, under, or emanating from the place or places of business
of any Obligated Party or any Subsidiary of an Obligated Party or arise out of
or result from the environmental condition of such location or locations or the
applicability of any governmental requirements relating to Hazardous Materials
(including, without limitation, CERCLA or any federal, state, or local
so-called "Superfund" or "Superlien" law, statute, law, ordinance, code, rule,
regulation, order, or decree), regardless of whether caused by or within the
control of any Obligated Party or any Subsidiary of an Obligated Party or the
Lender.  The Lender may employ separate counsel, and the Obligated Parties,
jointly and severally, shall pay the fees and expenses of such separate
counsel.

                 (c)      THE PARTIES INTEND FOR THE PROVISIONS OF SUBSECTIONS
(A) AND (B) TO APPLY TO AND PROTECT EACH INDEMNITEE FROM THE CONSEQUENCES OF
ITS OWN NEGLIGENCE,  WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING,
OR CONCURRING CAUSE OF ANY CLAIM.

         9.18    EXPENSES.  The Obligated Parties, jointly and severally, agree
to pay all costs and expenses (such expenses to include all investigation,
audit, legal (which shall be reasonable), appraisal, valuation, filing,
printing, insurance, and environmental adviser, accountant, auditor, and other
consultant or adviser expenses and all document duplication, reproduction, and
other out-of-pocket expenses) incurred by the Lender in connection with the
negotiation and preparation of this Agreement, the other Loan Documents, any
documents executed or filed in connection herewith; the creation, perfection,
protection, and insurance of Liens in and the maintenance of the Collateral and
the filing, recording, of any financing statement and all amendments or
modifications thereto and any and all other documents or instruments to be
filed by the terms hereof; the negotiation or preparation of any and all
amendments, modifications, supplements, assignments, consents, waivers, or





REVOLVING CREDIT AGREEMENT, PAGE 47
<PAGE>   53
other documents or instruments related hereto; and the collection of the
Obligations, or enforcement of this Agreement.

         9.19    NOTICES.  Except as otherwise specifically provided herein,
whenever this Agreement requires or permits any consent, approval, notice,
request, or demand from one party to another, the same must be in writing
(including telecopy, telegram, telex, or cable) to be effective and shall be
deemed commercially reasonable and to have been given (a) in the case of notice
from the Lender to any Obligated Party on the earlier of, (i) if mailed, the
third (3rd) Business Day after it is duly deposited in the United States mail
first class postage paid, addressed to the party to be notified or, (ii) in the
case of notice given by any other means than mailing, the Business Day on which
it is received or, (b) in the case of notice from any Obligated Party to the
Lender on the Business Day it is received.  The address of each party hereto is
set forth below each party's name on the signature pages hereof.  Any Person
may change its address of notice by giving notice to all other parties hereto.

         9.20    NON-BUSINESS DAYS.  Except as otherwise specifically provided
herein, if any act hereunder is required to be taken on a day which is not a
Business Day, such act shall be taken on the next succeeding Business Day.

         9.21    GOVERNING LAW.  This Agreement and the other Loan Documents
are performable in New York City, New York and the laws of the State of New
York shall govern the determination of each issue relating to this Agreement,
including validity, construction, enforcement, and interpretation of each
provision of this Agreement, the other Loan Documents, and all other documents
executed in connection herewith, except as to provisions thereof relating to
the rate of interest to be charged to the extent the laws of the State of New
York with respect thereto may be preempted by federal law (or to the extent
federal law otherwise would allow a higher rate of interest than would be
allowed by the laws of the State of New York), in which case such federal law
shall apply.

         9.22    JURISDICTION; VENUE; SERVICE OF PROCESS.  To the extent not
prohibited by law in effect from time to time, the Lender and each Obligated
Party hereby irrevocably submits itself to the jurisdiction of any New York
state court or any United States court located in the State of New York (and
any court having jurisdiction over appeals from any such court) in any
proceeding between or among them arising out of or in any manner related to
this Agreement or any of the other Loan Documents, whether arising in contract,
tort, or otherwise.  Any such suit, action, or proceeding may be brought in the
state or federal courts located in the City of New York, State of New York.
Each Obligated Party agrees that service of all writs, process, and summonses
in any such suit, action, or proceeding may be made on the Borrower ("PROCESS
AGENT").  Each Obligated Party hereby irrevocably appoints Process Agent, as
its true and lawful attorney-in-fact in its name, place,





REVOLVING CREDIT AGREEMENT, PAGE 48
<PAGE>   54
and stead to accept such service of any and all such writs, process, and
summonses, and agrees that the failure of Process Agent to give any notice of
such service of process to it shall not impair or affect the validity of such
service or of any judgment based thereon.  Each Obligated Party also
irrevocably consents to the service of process in any suit, action, or
proceeding in said court by the mailing thereof, by registered or certified
mail, postage prepaid, to Process Agent or to its address for notices set forth
herein.  Service shall be deemed effective five (5) days after such mailing.
Each Obligated Party irrevocably waives any objections which it may now or
hereafter have (including any based on the grounds of forum non conveniens) to
the laying of venue of any suit, action, or proceeding arising out of or
relating to any of the Loan Documents brought in the state or federal courts
located in the City of New York, State of New York.  Nothing herein impairs the
right to bring proceedings in the courts of any other jurisdiction or to effect
service of process in any other permitted manner.

         9.23    WAIVER OF JURY TRIAL.  TO THE MAXIMUM EXTENT PERMITTED BY LAW,
EACH OBLIGATED PARTY HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION
OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT OR UNDER ANY
OTHER LOAN DOCUMENT, WAIVER, MODIFICATION, CONSENT, SUPPLEMENT, AMENDMENT,
INSTRUMENT, DOCUMENT, OR AGREEMENT DELIVERED OR WHICH MAY IN THE FUTURE BE
DELIVERED IN CONNECTION HEREWITH OR ARISING FROM OR RELATING TO THIS AGREEMENT,
THE OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY, AND AGREES

         All Advances and payments made on account of the principal hereof may
be endorsed by the holder hereof on the schedule attached hereto (provided that
any failure of the Lender or such holder to make any such endorsement shall not
affect the obligations of the Borrower hereunder in respect of such Advance.

         The Borrower and each Surety hereby severally (a) waive grace, demand,
presentment for payment, notice of nonpayment, protest, notice of protest,
non-payment or dishonor, notice of intent to accelerate, notice of acceleration
and all other notices (except as explicitly provided in the Agreement), filing
of suit and diligence in collecting this Note or enforcing any other security
with respect to same, (b) agree to any substitution, surrender, subordination,
waiver, modification, change, exchange or release of any security or of the
liability of any parties primarily or secondarily liable hereon, (c) agree that
the Lender is not required first to institute suit or exhaust its remedies
hereon against the Borrower, any Surety or others liable or to become liable
hereon or to enforce its rights against them or any security with respect to
same, and (d) consent to any extension or postponement of time of payment of
this Note and to any other indulgence with respect hereto without notice
thereof to any of them.  No failure or delay on  the part of the Lender in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof.

         If this Note is not paid at maturity, regardless of how such maturity
may be brought about, or is collected or attempted to be collected through the
initiation or prosecution of any suit or through any bankruptcy or other
judicial proceedings, or is placed in the hands of an attorney for collection,
the Borrower shall pay, in addition to all other amounts owing hereunder, all
actual expenses of collection, all court costs and reasonable attorney's fees
incurred by the holder hereof.

         This Note and the rights and obligations of the parties hereunder
shall be governed by the laws of the United States of America and by the laws
of the State of NEW YORK, provided that to the extent the laws of the United
States of America may permit the Lender to contract for, charge, receive, take,
or reserve interest hereon at a higher rate governed by the laws of another
state, the laws of such other state shall with respect to such matters govern.
This Note is performable in NEW YORK CITY, NEW YORK.

         All agreements between the Borrower and the Lender, whether now
existing or hereafter arising, are hereby limited so that in no event shall the
amount paid, or agreed to be paid to or charged or demanded by the Lender for
the use, forbearance, or detention of money or for the payment or performance
of any covenant or obligation contained herein or in any other document
evidencing, securing or pertaining to this Note, exceed the Legal Maximum.  If

any circumstance otherwise would cause the amount paid, charged or demanded to
exceed the Legal Maximum, the amount paid or agreed to be paid to or charged or
demanded by the Lender shall be reduced to the Legal Maximum, and if the Lender
ever receives an amount which otherwise would exceed the Legal Maximum, such
amount which would be excessive interest shall be applied to the reduction of
the principal of this Note and not to the payment of interest, or to the extent
such excessive amount otherwise would exceed the unpaid balance of principal of
this Note such excess shall be applied first to other indebtedness of the
Borrower to the Lender, and the balance, if any, shall be refunded to the
Borrower.  In determining whether the interest paid, agreed to be paid, charged
or demanded hereunder exceeds the Legal Maximum, all sums paid or agreed to be
paid to or charged or demanded by the Lender for the use, forbearance or
detention of the indebtedness of the Borrower to the Lender shall, to the
extent permitted by applicable law, (i) be amortized, prorated, allocated and
spread throughout the full term of such indebtedness until payment in full so
that the actual rate of interest on account of such indebtedness is uniform
throughout such term, (ii) be characterized as a fee, expense or other charge
other than interest, and (iii) exclude any voluntary prepayments and the
effects thereof.  The terms and provisions of this paragraph shall control and
supersede every other provision of all agreements between the Lender and the
Borrower in conflict herewith.
