                             ANNOUNCES THE SALE OF
                              CANADIAN SUBSIDIARY

Bartonville, TX  October 12, 1999 - The UniMark Group, Inc. (NASDAQ NMS symbol:
"UNMG"), producer and marketer of Sunfresh(R) brand citrus and tropical fruit
products, announced today that it has sold its Canadian subsidiary, Les
Produits Deli-Bon Inc. in a transaction valued at approximately $1.4 million.
Deli-Bon, a fruit processing company located in Quebec City, primarily sells
fruit salads to the foodservice industry and warehouse clubs in the Province of
Quebec. For the year ended December 31, 1998, Deli-Bon had net sales of US
$4.2 million. In connection with the transaction, UniMark entered into a
supply and distribution agreement that will allow for the continued supply of
existing UniMark products in Canada.

Also, UniMark announced that it is discontinuing its Fruit Jelite product
line, which was being produced at Deli-Bon. The discontinuation of this
product line is expected to result in a one-time charge of approximately
$400,000.

"The Deli-Bon divestiture represents a significant step in furthering the
strategic objective for our packaged food segment, which is to leverage our
Sunfresh(R) brand to build a leading branded packaged food company with
production based in Mexico.  We believe that the supply and distribution
agreements will allow for continued production in our Mexican facilities for
export to Canada. Since our Sunfresh(R) product lines have historically
performed well, we believe that by consolidating our operations in Mexico and
increasing sales and marketing efforts for Sunfresh(R) products, we are
strategically positioning our company for future growth and profitability," said
Soren Bjorn, President and CEO.

$400,000 (U.S.)                   Dallas, Texas                October 11, 1999


         FOR VALUE RECEIVED, the undersigned, Francois Gravil - Guy Picard, in
trust for the company to be owned and operated by Francois Gravil and Guy Picard
("Maker"), promises to pay to the order of The UniMark Group, Inc., a Texas
corporation ("Payee"), whose principal office is located at 124 McMakin Road,
Bartonville, Texas 76226, the principal sum of Four Hundred Thousand Dollars
($400,000), payable as provided herein, without interest.

         The principal shall be due and payable by the Maker to the Payee on
November 10, 1999 (30 days from October 11, 1999).

         Principal under this Note, or any portion thereof, may be prepaid
without penalty.

         This Note is issued and delivered under and in subject to the terms and
provisions of that certain Stock Purchase Agreement (the "Stock Purchase
Agreement") dated of even date herewith, by and among Payee and Maker. This Note
is secured by a Short-term Pledge Agreement and a Long-term Pledge Agreement
(collectively, the "Pledge Agreements"), each dated October 11, 1999, executed
by the undersigned in favor of the holder hereto, covering all of the issued and
outstanding shares of capital stock of Les Produits Deli-Bon, Inc., a Quebec
corporation ("Deli-Bon") more fully described in Exhibit A hereto attached
hereto (the "Deli-Bon Shares"). Reference is made to the Pledge Agreements for a
statement of the rights and obligations of the Payee, a description of the
nature and extent of the security and the rights of the parties in respect to
such security.

         Maker, and any endorser or guarantors of this Note and all other
persons who may become liable for all or any part of the obligations represented
by this Note, severally waive presentment for payment, protest, notice of
protest and of nonpayment, notice of intention to accelerate, and notice of
acceleration.

          The following shall constitute Events of Default ("Event(s) of
Default"):

                  (a) default in the due and punctual payment of the principal
         of the Note when and as such payment shall become due and payable,
         whether at maturity or by acceleration or otherwise if such payment is
         not made within ten (10) days of written notice mailed by Payee to
         Maker; or

                  (b) default in the performance or observance of any covenant
         or agreement of Maker in this Note or the Pledge Agreements other than
         as described in paragraph (a) above and the continuance of such default
         for a period of seven (7) days after the Payee has sent Maker written
         notice specifying such default and requiring that it be remedied,
         provided that no such default shall be deemed to occur if such default
         may not be cured within seven (7) days, if within said period the Maker
         has commenced and thereafter



<PAGE>   10


         diligently and continuously pursues to cure such default, and the
         default is cured, in any event, within fourteen (14) days; or

                  (c) the filing by the Maker of a petition instituting any
         state or federal insolvency, bankruptcy, reorganization, arrangement,
         composition, or other debtor relief proceeding; the petition of or
         application to any tribunal for a receiver or trustee for itself or for
         any substantial part of any of its property; or

                  (d) the sale or transfer of all or substantially all of the
         assets of Deli-Bon or Maker.

         If an Event of Default occurs, then and in any such case Payee may
declare the outstanding principal amount of the Note to be due and payable
immediately, upon written notice to the Maker, and, upon any such declaration,
the outstanding principal amount of the Note, together with all costs of
collection, including reasonable attorneys' fees if collected by law or through
an attorney at law, shall immediately become due and payable.

         Not withstanding anything to the contrary contained herein, no
provisions of this Note shall require the payment or permit the collection of
interest in excess of the maximum rate permitted by applicable law. If any
interest in excess of such maximum rate is herein provided for, or shall be
adjudicated to be so provided, in this Note or otherwise in connection with this
transaction giving rise to the execution hereof, the provisions of this
paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of the Maker shall be obligated to pay the
excess amount of such interest or any other excess sum paid for the use,
forbearance or detention of sums loaned pursuant hereto. If for any reason
interest in excess of the maximum rate of interest permitted by applicable law
shall be deemed, charged, required or permitted by a court of competent
jurisdiction, any such excess shall be applied as a payment and reduction of the
principal of indebtedness evidenced by this Note; and, if the principal amount
hereof has been paid in full, any remaining excess shall forthwith be paid to
Maker.

         This note is made and is performable in Bartonville, Denton County,
Texas, and Maker waives the right to be sued hereon elsewhere. This Note shall
be governed by and construed in accordance with the laws of the State of Texas
and the applicable laws of the United States of America.

         SECTION 3.1 Warranties, etc. Pledgor represents and warrants unto the

         (a) Pledgor has all requisite power and authority, and has taken all
         necessary corporate action, to execute and deliver and perform its
         obligations under this Pledge Agreement and to pledge the Collateral
         hereunder.

         (b) The execution, delivery and performance of this Agreement by
         Pledgor, and the pledge of the Collateral hereunder do not and will not
         conflict with, result in any violation of, or constitute any default
         under, any provision of any contractual obligation of Pledgor or any
         law or government regulation or court decree or order and will not
         result in or require the creation or imposition of any lien on any of
         Pledgor's properties pursuant to the provisions of any contractual
         obligation. This Agreement is the legal, valid and binding obligation
         of Pledgor enforceable in accordance with its terms subject to the
         effect of

                           (i) any applicable bankruptcy, insolvency or similar
                  laws affecting creditors' rights generally; and



<PAGE>   18



                           (ii) general principles of equity (regardless of
                  whether considered in a proceeding in equity or at law).

         (c) Except as disclosed in the Purchase Agreement, there is no pending
         or, to the knowledge of Pledgor, threatened litigation, arbitration or
         governmental investigation, proceeding or inquiry against Pledgor, or
         to which any of its properties, assets or revenues is subject.

         (d) Pledgor will be the legal and beneficial owner of, and will have
         good and marketable title to (and will have full right and authority to
         pledge and assign) all Collateral, free and clear of all liens or other
         charges or encumbrances, except any lien or security interest granted
         pursuant hereto in favor of the Secured Party.

         (e) The delivery of the Collateral (including the delivery of the
         Initial Pledged Shares) to the Secured Party will be effective to
         create a valid, perfected, first priority security interest in such
         Collateral and all proceeds thereof, securing the Secured Obligations,
         and no filing or other action will be necessary to perfect or protect
         such security interest.

         (f) In the case of any Pledged Shares constituting Collateral, all of
         such Pledged Shares will be duly authorized and validly issued, fully
         paid, and non-assessable.

         (g) No authorization, approval, or other action by, and no notice to or
         filing with, any governmental authority will be required either

                           (i) for the pledge by Pledgor of any Collateral
                  pursuant to this Agreement or for the execution, delivery, or
                  performance of this Agreement by Pledgor, or

                           (ii) for the exercise by the Secured Party of the
                  voting or other rights provided for in this Agreement, or
                  (except, with respect to any Pledged Shares, as may be
                  required in connection with a disposition of such Pledged
                  Shares by laws affecting the offering and sale of securities
                  generally) the remedies in respect of the Collateral pursuant
                  to this Agreement.

                                    COVENANTS

         SECTION 4.1 Protect Collateral; Further Assurances. etc. Pledgor will
not sell, assign, transfer, pledge or encumber in any other manner the
Collateral (except in favor of the Secured Party hereunder). Pledgor will
warrant and will use its best efforts to defend the right and title herein
granted unto the Secured Party in and to the Collateral (and all right, title
and interest represented by the Collateral) against the claims and demands of
all Persons whomsoever. Pledgor agrees that at any time, and from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments, and take all further action, that may be necessary or desirable, or
that the Secured Party may reasonably request, in order to perfect and protect
any security interest granted or purported to be granted hereby or to enable the
Secured Party to exercise and enforce its rights and remedies hereunder with
respect to any Collateral.


<PAGE>   19



         SECTION 4.2 Stock Powers, etc. Pledgor agrees that all Pledged Shares
(and all other shares of capital stock constituting Collateral) delivered by
Pledgor pursuant to this Agreement will be accompanied by duly executed undated
blank stock powers, or other equivalent instruments of transfer acceptable to
the Secured Party. Pledgor will, from time to time upon the request of the
Secured Party, promptly deliver to the Secured Party such stock powers,
instruments and similar documents, satisfactory in form and substance to the
Secured Party, with respect to the Collateral as the Secured Party may
reasonably request and will, from time to time upon the request of the Secured
Party after the occurrence of any default, promptly transfer any Pledged Shares
or other shares of stock constituting Collateral into the name of the Secured
Party or any nominee designated by the Secured Party.

         SECTION 4.3 Continuous Pledge. Pledgor will, at all times, keep pledged
to the Secured Party pursuant hereto all Pledged Shares and all other shares of
stock constituting Collateral, all Dividends and Distributions with respect
thereto, and all other Collateral and other securities, instruments, proceeds
and rights from time to time received by or distributable to Pledgor in respect
of any Collateral.

         SECTION 4.4 Voting Rights; Dividends, etc. Pledgor agrees to deliver
all Distributions at any time received by it to the Secured Party to be held as
Collateral hereunder and, in addition, to deliver (properly endorsed where
required hereby or requested by the Secured Party) to the Secured Party:

         (a) after any Default shall have occurred and be continuing or if any
         Default shall occur as a result thereof, promptly upon receipt thereof
         by Pledgor and without any request therefor by the Secured Party, all
         Dividends, all other cash payments and all proceeds of the Collateral,
         all of which shall be held by the Secured Party as additional
         collateral for use in accordance with Section 5.4; and

         (b) after any Default shall have occurred and be continuing, promptly
         upon request of the Secured Party, such proxies and other documents as
         may be necessary to allow the Secured Party to exercise the voting
         power with respect to any share of capital stock constituting
         Collateral;

provided, however, that unless a default shall have occurred and be continuing
or result therefrom, Pledgor shall be entitled to exercise, in its reasonable
judgment, but in a manner not inconsistent with the terms of the Purchase
Agreement or any other Loan Document (including this Agreement), the voting
power and all other incidental rights of ownership with respect to any Pledged
Shares or other shares of capital stock constituting Collateral (subject to
Pledgor's obligation to deliver to the Secured Party such Pledged Shares and
other shares in pledge hereunder).

All Dividends, Distributions, cash payments and proceeds which may at any time
and from time to time be held by Pledgor but which Pledgor is then obligated to
deliver to the Secured Party, shall, until delivery to the Secured Party, be
held by Pledgor separate and apart from its other property in trust for the
Secured Party. The Secured Party agrees that unless a Default shall have
occurred and be continuing, the Secured Party shall, upon the written request of
Pledgor, promptly deliver such proxies and other documents, if any, as shall be
reasonably requested by Pledgor which are necessary to allow Pledgor to exercise
voting power with respect to any share of capital stock (including Pledged
Shares) constituting Collateral; provided, however that no vote shall be cast,
or consent,


<PAGE>   20



waiver or ratification given, or action taken by Pledgor that would impair any
Collateral or be inconsistent with or violate any provision of the Purchase
Agreement or any other Loan Document (including this Agreement).

         SECTION 4.5 Sale of Assets. Pledgor will not sell, assign, transfer,
pledge or encumber all or substantially all of the assets that are necessary for
the operations of Deli-Bon as presently conducted.

         SECTION 4.6 Payment of the Obligations. The Pledgor will pay each part
of the 30 Day Note and the 60 Day Note and obligations under the Purchase

punctually perform and observe all agreements, covenants, and obligations
contained in the Loan Documents and any other agreement between it and the
Secured Party.

         SECTION 4.8 Books and Records; Inspection. Pledgor will maintain in a
secure place on the Pledgor's premises, complete proper and accurate books,
records, ledgers, correspondence, and other papers relating to Deli-Bon's
business and affairs. The Secured Party will at all reasonable times have the
right to examine, inspect, audit, verify, and copy such items, and to remove
copies thereof and to discuss any of same with appropriate officers,
accountants, and auditors of Pledgor.

         SECTION 4.9 Notice of Default. Within twenty-four (24) hours of the
discovery by Pledgor of the occurrence of a Default or Event of Default
hereunder or under any of the other Transaction Documents or an event which
could reasonably be expected to result in a Default or Event of Default
hereunder or under any other Loan Document, the Pledgor will notify the Secured
Party and will deliver a certificate signed by the president, chief executive
officer or the chief financial officer of the Pledgor concerning the nature and
period of existence thereof and the steps, if any, being taken to cure such
Default or Event of Default.

         SECTION 4.10 Maintenance of Existence, Approvals, and Licenses. Pledgor
will preserve and maintain Deli-Bon's existence, rights, privileges, operations
and franchises in its jurisdiction of creation, qualify and remain qualified in
each jurisdiction in which, under then applicable law, the nature of its
business or the ownership of its properties requires such qualification and
obtain and maintain in full force all approvals, licenses (governmental and
private) permits, and authorizations necessary to conduct its business and
comply with its obligations under the Loan Documents. Pledgor will continue to
operate Deli-Bon in a prudent and businesslike manner.

         SECTION 4.11 Compliance with Laws, Material Agreements, and Licenses.
Pledgor will comply with all foreign and domestic laws, rules, regulations,
ordinances, orders, judgments, and decrees applicable to it or any of its
property, a breach of which (when considered alone or when aggregated with the
effect of other breaches) could have a material adverse effect, will comply in
all respects with all material agreements, indentures, mortgages, leases, and
other documents to which it is a party or by which it or any of its property is
bound and will keep in full force and effect all material licenses, permits, and
franchises necessary or useful for the conduct of its business.

         SECTION 4.12 Maintenance of Assets and Insurance. Pledgor will keep all
assets which are useful and necessary in the business in good working order and
condition, make all necessary replacements and maintain, or cause to be
maintained, such insurance as is customarily maintained


<PAGE>   21



by other businesses of comparable type and size with such financially sound and
reputable insurers, in such amounts and covering such risks as shall be
satisfactory and acceptable to the Secured Party.

         SECTION 4.13 Financial Information. Pledgor will furnish to the Secured
Party with seven (7) days (a) such financial information and information
regarding Payee and Deli-Bon as the Secured Party may from time to time
reasonably request and (b) written notice of the occurrence of any event which
would make any representation contained in Article III untrue at such time.


                                    ARTICLE 5

                                    REMEDIES

         SECTION 5.1 Actions upon Event of Default. In addition to its rights
and remedies provided hereunder, whenever an Event of Default shall have
occurred and be continuing, the Secured Party shall have all rights and remedies
of a secured party upon default under the U.C.C. or other applicable law. Any
notification required by law of any intended disposition by the Secured Party of
any of the Collateral shall be deemed reasonably and properly given if given at
least 15 days before such disposition. Without limitation of the above, the
secured Party may, whenever an Event of Default shall have occurred and be
continuing, without prior notice to Pledgor, take all or any of the following
actions:

         (a) transfer all or any part of the Collateral into the name of the
         Secured Party or its nominee, with or without disclosing that such
         Collateral is subject to the lien and security interest hereunder;

         (b) notify the parties obligated on any of the Collateral to make
         payment to the Secured Party of any amount due or to become due
         thereunder;

         (c) enforce collection of any of the Collateral by suit or otherwise,
         and surrender, release or exchange all or any part thereof, or
         compromise or extend or renew for any period (whether or not longer
         than the original period) any obligations of any nature of any party
         with respect thereto;

         (d) endorse any checks, drafts, or other writings in Pledgor's name to
         allow collection of the Collateral;

         (e) take control of any proceeds of the Collateral; and

         (f) execute (in the name, place and stead of Pledgor) endorsements,
         assignments, stock powers and other instruments of conveyance or
         transfer with respect to all or any of the Collateral.

         SECTION 5.2 Attorney-in-Fact. Pledgor hereby irrevocably appoints the
Secured Party its attorney-in-fact, with full authority in the place and stead
of Pledgor and in the name of Pledgor, the Secured Party, or otherwise, from
time to time in the Secured Party's discretion, to take any action and to
execute any instrument which the Secured Party may deem necessary or advisable
to


<PAGE>   22



accomplish the purposes of this Agreement, including, upon the occurrence and
continuance of an Event of Default, all actions described in Section 5.1.

         SECTION 5.3 Private Sales.

         (a) Pledgor recognizes that the Secured Party may be unable to effect a
         public sale of any or all the Pledged Shares by reason of certain
         prohibitions contained in the Securities Act of 1933, as amended (the
         "Securities Act") and applicable state securities laws or otherwise,
         and may be compelled to resort to one or more private sales thereof to
         a restricted group of purchasers that will be obliged to agree, among
         other things, to acquire such securities for their own account for
         investment and not with a view to the distribution or resale thereof.
         Pledgor acknowledges and agrees that any such private sale may result
         in prices and other terms less favorable than if such sale were a
         public sale and, notwithstanding such circumstances, agrees that any
         such private sale shall be deemed to have been made in a commercially
         reasonable manner. The Secured Party shall be under no obligation to
         delay sale of any of the Pledged Shares for the period of time
         necessary to permit the Pledgor to register such securities for public
         sale under the Securities Act, or under applicable state securities
         laws, even if Deli-Bon would agree to do so.

         (b) Pledgor further agrees to use its best efforts to do or cause to be
         done all such acts as may be necessary to make such sale or sales of
         all or any portion of the Pledged Shares pursuant to this Section 5.3
         valid and binding and in compliance with any and all other applicable
         requirements of law.

         SECTION 5.4 Application of Proceeds. All cash proceeds received by the
Secured Party in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral may, in the discretion of the Secured
Party, be held by the Secured Party as additional collateral security for, or
then or at any time thereafter be applied in whole or in part by the Secured
Party against, all or any part of the Secured Obligations in the following
order:

         (a) first, Ratably, to the principal then due on the 30 Day Note;

         (b) second, Ratably, to the principal then due on the 60 Day Note;

         (c) third, to any other Secured Obligations then due or owing.

Any surplus of such cash or cash proceeds held by the Secured Party and
remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.

         SECTION 5.5 Indemnity and Expenses. Pledgor hereby indemnifies and
holds harmless the Secured Party from and against any and all claims, losses,
and liabilities growing out of or resulting from this Agreement (including
enforcement of this Agreement), except claims, losses, or liabilities resulting
from the Secured Party's gross negligence or wilful misconduct. Upon demand,
Pledgor will pay, or cause to be paid, to the Secured Party the amount of any
and all reasonable expenses, including the reasonable fees and disbursements of
its counsel and of any experts and agents, which the Secured Party may incur in
connection with:



<PAGE>   23



         (a) the administration of this Agreement;

         (b) the custody, preservation, use, or operation of, or the sale of,
         collection from, or other realization upon, any of the Collateral;

         (c) the exercise or enforcement of any of the rights of the Secured
         Party hereunder and any action taken by the Secured Party under Section
         6.5; or

         (d) the failure by Pledgor to perform or observe any of the provisions
         hereof.

                                    ARTICLE 6

                                  MISCELLANEOUS

         SECTION 6.1 Amendments, etc. No amendment or waiver of any provision of
this Agreement nor consent to any departure by Pledgor herefrom shall in any
event be effective unless the same shall be in writing, signed by the Secured
Party and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it is given.

         SECTION 6.2 Obligations Not Affected. The obligations of Pledgor under
this Agreement shall remain in full force and effect without regard to, and
shall not be impaired or affected by:

         (a) any amendment or modification or addition or supplement to the
         Purchase Agreement, any other Loan Document, any instrument delivered
         in connection therewith or any assignment or transfer thereof;

         (b) any exercise, non-exercise or waiver by the Secured Party of any
         right, remedy, power or privilege under or in respect of, or any
         release of any guaranty or collateral provided pursuant to this
         Agreement, the Purchase Agreement or any Loan Document;

         (c) any waiver, consent, extension, indulgence or other action or
         inaction in respect of this Agreement, the Purchase Agreement or any
         Loan Document or any assignment or transfer of any thereof; or

         (d) any bankruptcy, insolvency, reorganization, arrangement,
         readjustment, composition, liquidation or the like, death or
         incompetency of the Pledgor or any other Person, whether or not Pledgor
         shall have notice or knowledge of any of the foregoing.

         SECTION 6.3 Protection of Collateral. The Secured Party may from time
to time, at its option, perform any act which Pledgor agrees hereunder to
perform and which Pledgor shall fail to perform after being requested in writing
to so perform (it being understood that no such request need be given after the
occurrence and during the continuance of an Event of Default) and the Secured
Party may from time to time take any other action which the Secured Party
reasonably deems necessary for the maintenance, preservation or protection of
any of the Collateral or of its security interest therein.

         SECTION 6.4 Addresses for Notices. All notices and other communications
provided for hereunder to any party hereto under this Agreement shall be in
writing or by facsimile and addressed


<PAGE>   24



or delivered to it at the address set forth below its signature hereto, or as to
any party at such other address as shall be designated by such party in a
written notice to each other party complying as to delivery with the terms of
this Section. Any such notice, if mailed and properly addressed with postage
prepaid, shall be deemed given seven (7) calendar days after mailing; any
notice, if transmitted by facsimile shall be deemed given when transmitted on a
business day (with evidence of transmission confirmation).

         SECTION 6.5 Governing Law; Jurisdiction.

         (a) THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

         (b) EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY SUBMITS TO THE
JURISDICTION OF ANY TEXAS STATE OR FEDERAL COURT SITTING IN DALLAS, TEXAS IN ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR RELATED DOCUMENT (AND PLEDGOR AGREES THAT SUCH JURISDICTION
WILL BE EXCLUSIVE WITH RESPECT TO CLAIMS BROUGHT BY PLEDGOR AGAINST THE SECURED
PARTY), AND EACH HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH TEXAS STATE OR FEDERAL
COURT. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT IT MAY EFFECTIVELY DO SO, THE DEFENSE OF ANY INCONVENIENT FORUM TO THE
MAINTENANCE OF SUCH ACTION OR PROCEEDING.

         (c) Pledgor hereby irrevocably designates, appoints and empowers C.T.
Corporation System, 350 N. St. Paul Street, Suite 2900, Dallas, Texas 75201, as
its authorized agent to receive, for and on its behalf and on behalf of its
property, service of process in the State of Texas when and as such legal
actions or proceedings may be brought in the courts of the State of Texas or of
the United States of America sitting in Texas, and such service of process shall
be deemed complete upon the date of delivery thereof to such agent whether or
not such agent gives notice thereof to Pledgor, or upon the earliest of any
other date permitted by applicable law. It is understood that a copy of said
process served on such agent will as soon as practicable be forwarded to
Pledgor, at its address set forth below, but Pledgor's failure to receive such
copy shall not affect in any way the service of said process on said agent as
the agent of Pledgor. Pledgor irrevocably consents to the service of process out
of any of the aforementioned courts in any such action or proceeding by the
mailing of the copies thereof by certified mail, return receipt requested,
postage prepaid, to Pledgor at its address set forth below, such service to
become effective upon the earlier of (i) the date 10 calendar days after such
mailing or (ii) any earlier date permitted by applicable law. Pledgor agrees
that it will at all times continuously maintain an agent to receive service of
process in the State of Texas and in the event that, for any reason, the agent
named above or its successor shall no longer serve as its agent to receive
service of process in the State of Texas on its behalf, it shall promptly
appoint a successor so to serve and shall advise the Secured Party. Nothing in
this Section 6.5 shall affect the right of the Secured Party to bring
proceedings against Pledgor in the courts of any other jurisdiction or to serve
process in any other manner permitted by applicable law.

         SECTION 6.6 Waiver of Jury Trial. Etc. THE SECURED PARTY, AND PLEDGOR
HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS


<PAGE>   25



THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT OR RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE SECURED PARTY OR
PLEDGOR. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE SECURED PARTY'S
ENTERING INTO THE PURCHASE AGREEMENT.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first above written.

         or agreement of Maker in this Note or the Pledge Agreements other than
         as described in paragraph (a) above and the continuance of such default
         for a period of seven (7) days after the Payee has sent Maker written
         notice specifying such default and requiring that it be remedied,
         provided that no such default shall be deemed to occur if such default
         may not be cured within seven (7) days, if within said period the Maker
         has commenced and thereafter



<PAGE>   30



         diligently and continuously pursues to cure such default, and the
         default is cured, in any event, within fourteen (14) days; or

         state or federal insolvency, bankruptcy, reorganization, arrangement,

paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of the Maker shall be obligated to pay the

forbearance or detention of sums loaned pursuant hereto. If for any reason
interest in excess of the maximum rate of interest permitted by applicable law

jurisdiction, any such excess shall be applied as a payment and reduction of the
principal of indebtedness evidenced by this Note; and, if the principal amount
hereof has been paid in full, any remaining excess shall forthwith be paid to
Maker.

         necessary corporate action, to execute and deliver and perform its
         obligations under this Pledge Agreement and to pledge the Collateral
         hereunder.

         (b) The execution, delivery and performance of this Agreement by
         Pledgor, and the pledge of the Collateral hereunder do not and will not
         conflict with, result in any violation of, or constitute any default
         under, any provision of any contractual obligation of Pledgor or any
         law or government regulation or court decree or order and will not
         result in or require the creation or imposition of any lien on any of
         Pledgor's properties pursuant to the provisions of any contractual
         obligation. This Agreement is the legal, valid and binding obligation
         of Pledgor enforceable in accordance with its terms subject to the
         effect of

         (c) Except as disclosed in the Purchase Agreement, there is no pending
         or, to the knowledge of Pledgor, threatened litigation, arbitration or
         governmental investigation,



<PAGE>   43



         proceeding or inquiry against Pledgor, or to which any of its
         properties, assets or revenues is subject.

         (d) Pledgor will be the legal and beneficial owner of, and will have
         good and marketable title to (and will have full right and authority to
         pledge and assign) all Collateral, free and clear of all liens or other
         charges or encumbrances, except any lien or security interest granted
         pursuant hereto in favor of the Secured Party.

         (e) The delivery of the Collateral (including the delivery of the
         Initial Pledged Shares) to the Secured Party will be effective to
         create a valid, perfected, first priority security interest in such
         Collateral and all proceeds thereof, securing the Secured Obligations,
         and no filing or other action will be necessary to perfect or protect
         such security interest.

         (f) In the case of any Pledged Shares constituting Collateral, all of
         such Pledged Shares will be duly authorized and validly issued, fully
         paid, and non-assessable.

         (g) No authorization, approval, or other action by, and no notice to or
         filing with, any governmental authority will be required either

                           (i) for the pledge by Pledgor of any Collateral
                  pursuant to this Agreement or for the execution, delivery, or
                  performance of this Agreement by Pledgor, or

                           (ii) for the exercise by the Secured Party of the
                  voting or other rights provided for in this Agreement, or
                  (except, with respect to any Pledged Shares, as may be
                  required in connection with a disposition of such Pledged
                  Shares by laws affecting the offering and sale of securities
                  generally) the remedies in respect of the Collateral pursuant
                  to this Agreement.


                                   ARTICLE 10

                                    COVENANTS

         SECTION 10.1 Protect Collateral; Further Assurances. etc. Pledgor will
not sell, assign, transfer, pledge or encumber in any other manner the
Collateral (except in favor of the Secured Party hereunder). Pledgor will
warrant and will use its best efforts to defend the right and title herein
granted unto the Secured Party in and to the Collateral (and all right, title
and interest represented by the Collateral) against the claims and demands of
all Persons whomsoever. Pledgor agrees that at any time, and from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments, and take all further action, that may be necessary or desirable, or
that the Secured Party may reasonably request, in order to perfect and protect
any security interest granted or purported to be granted hereby or to enable the
Secured Party to exercise and enforce its rights and remedies hereunder with
respect to any Collateral.

         SECTION 10.2 Stock Powers, etc. Pledgor agrees that all Pledged Shares
(and all other shares of capital stock constituting Collateral) delivered by
Pledgor pursuant to this Agreement



<PAGE>   44



will be accompanied by duly executed undated blank stock powers, or other
equivalent instruments of transfer acceptable to the Secured Party. Pledgor
will, from time to time upon the request of the Secured Party, promptly deliver
to the Secured Party such stock powers, instruments and similar documents,
satisfactory in form and substance to the Secured Party, with respect to the
Collateral as the Secured Party may reasonably request and will, from time to
time upon the request of the Secured Party after the occurrence of any default,
promptly transfer any Pledged Shares or other shares of stock constituting
Collateral into the name of the Secured Party or any nominee designated by the
Secured Party.

         SECTION 10.3 Continuous Pledge. Pledgor will, at all times, keep
pledged to the Secured Party pursuant hereto all Pledged Shares and all other
shares of stock constituting Collateral, all Dividends and Distributions with
respect thereto, and all other Collateral and other securities, instruments,
proceeds and rights from time to time received by or distributable to Pledgor in
respect of any Collateral.

         SECTION 10.4 Voting Rights; Dividends, etc. Pledgor agrees to deliver
all Distributions at any time received by it to the Secured Party to be held as
Collateral hereunder and, in addition, to deliver (properly endorsed where
required hereby or requested by the Secured Party) to the Secured Party:

         (a) after any Default shall have occurred and be continuing or if any
         Default shall occur as a result thereof, promptly upon receipt thereof
         by Pledgor and without any request therefor by the Secured Party, all
         Dividends, all other cash payments and all proceeds of the Collateral,
         all of which shall be held by the Secured Party as additional
         collateral for use in accordance with Section 5.4; and

         (b) after any Default shall have occurred and be continuing, promptly
         upon request of the Secured Party, such proxies and other documents as
         may be necessary to allow the Secured Party to exercise the voting
         power with respect to any share of capital stock constituting
         Collateral;

provided, however, that unless a default shall have occurred and be continuing
or result therefrom, Pledgor shall be entitled to exercise, in its reasonable
judgment, but in a manner not inconsistent with the terms of the Purchase
Agreement or any other Loan Document (including this Agreement), the voting
power and all other incidental rights of ownership with respect to any Pledged
Shares or other shares of capital stock constituting Collateral (subject to
Pledgor's obligation to deliver to the Secured Party such Pledged Shares and
other shares in pledge hereunder).

All Dividends, Distributions, cash payments and proceeds which may at any time
and from time to time be held by Pledgor but which Pledgor is then obligated to
deliver to the Secured Party, shall, until delivery to the Secured Party, be
held by Pledgor separate and apart from its other property in trust for the
Secured Party. The Secured Party agrees that unless a Default shall have
occurred and be continuing, the Secured Party shall, upon the written request of
Pledgor, promptly deliver such proxies and other documents, if any, as shall be
reasonably requested by Pledgor which are necessary to allow Pledgor to exercise
voting power with respect to any share of capital stock (including Pledged
Shares) constituting Collateral; provided, however that no vote shall be cast,
or consent,



<PAGE>   45



waiver or ratification given, or action taken by Pledgor that would impair any
Collateral or be inconsistent with or violate any provision of the Purchase
Agreement or any other Loan Document (including this Agreement).

         SECTION 10.5 Sale of Assets. Pledgor will not sell, assign, transfer,
pledge or encumber all or substantially all of the assets that are necessary for
the operations of Deli-Bon as presently conducted.

         SECTION 10.6 Payment of the Obligations. The Pledgor will pay each part
of the 30 Day Note, 60 Day Note, 5 Year Note and obligations under the Purchase
Agreement when due.

         SECTION 10.7 Agreements. Pledgor will comply with and duly and
punctually perform and observe all agreements, covenants, and obligations
contained in the Loan Documents and any other agreement between it and the
Secured Party.

         SECTION 10.8 Books and Records; Inspection. Pledgor will maintain in a
secure place on the Pledgor's premises, complete proper and accurate books,
records, ledgers, correspondence, and other papers relating to Deli-Bon's
business and affairs. The Secured Party will at all reasonable times have the
right to examine, inspect, audit, verify, and copy such items, and to remove
copies thereof and to discuss any of same with appropriate officers,
accountants, and auditors of Pledgor.

         SECTION 10.9 Notice of Default. Within twenty-four (24) hours of the
discovery by Pledgor of the occurrence of a Default or Event of Default
hereunder or under any of the other Transaction Documents or an event which
could reasonably be expected to result in a Default or Event of Default
hereunder or under any other Loan Document, the Pledgor will notify the Secured
Party and will deliver a certificate signed by the president, chief executive
officer or the chief financial officer of the Pledgor concerning the nature and
period of existence thereof and the steps, if any, being taken to cure such
Default or Event of Default.

         SECTION 10.10 Maintenance of Existence, Approvals, and Licenses.
Pledgor will preserve and maintain Deli-Bon's existence, rights, privileges,
operations and franchises in its jurisdiction of creation, qualify and remain
qualified in each jurisdiction in which, under then applicable law, the nature
of its business or the ownership of its properties requires such qualification
and obtain and maintain in full force all approvals, licenses (governmental and
private) permits, and authorizations necessary to conduct its business and
comply with its obligations under the Loan Documents. Pledgor will continue to
operate Deli-Bon in a prudent and businesslike manner.

         SECTION 10.11 Compliance with Laws, Material Agreements, and Licenses.
Pledgor will comply with all foreign and domestic laws, rules, regulations,
ordinances, orders, judgments, and decrees applicable to it or any of its
property, a breach of which (when considered alone or when aggregated with the
effect of other breaches) could have a material adverse effect, will comply in
all respects with all material agreements, indentures, mortgages, leases, and
other documents to which it is a party or by which it or any of its property is
bound and will keep in full force and effect all material licenses, permits, and
franchises necessary or useful for the conduct of its business.




<PAGE>   46


         SECTION 10.12 Maintenance of Assets and Insurance. Pledgor will keep
all assets which are useful and necessary in the business in good working order
and condition, make all necessary replacements and maintain, or cause to be
maintained, such insurance as is customarily maintained by other businesses of
comparable type and size with such financially sound and reputable insurers, in
such amounts and covering such risks as shall be satisfactory and acceptable to
the Secured Party.

         SECTION 10.13 Financial Information. Pledgor will furnish to the
Secured Party within seven (7) days (a) such financial information and
information regarding Payee and Deli-Bon as the Secured Party may from time to
time reasonably request and (b) written notice of the occurrence of any event
which would make any representation contained in Article III untrue at such
time.


                                   ARTICLE 11

                                    REMEDIES

         SECTION 11.1 Actions upon Event of Default. In addition to its rights
and remedies provided hereunder, whenever an Event of Default shall have
occurred and be continuing, the Secured Party shall have all rights and remedies
of a secured party upon default under the U.C.C. or other applicable law. Any
notification required by law of any intended disposition by the Secured Party of
any of the Collateral shall be deemed reasonably and properly given if given at
least 15 days before such disposition. Without limitation of the above, the
secured Party may, whenever an Event of Default shall have occurred and be
continuing, without prior notice to Pledgor, take all or any of the following
actions:

         (a) transfer all or any part of the Collateral into the name of the
         Secured Party or its nominee, with or without disclosing that such
         Collateral is subject to the lien and security interest hereunder;

         (b) notify the parties obligated on any of the Collateral to make
         payment to the Secured Party of any amount due or to become due
         thereunder;

         (c) enforce collection of any of the Collateral by suit or otherwise,
         and surrender, release or exchange all or any part thereof, or
         compromise or extend or renew for any period (whether or not longer
         than the original period) any obligations of any nature of any party
         with respect thereto;

         (d) endorse any checks, drafts, or other writings in Pledgor's name to
         allow collection of the Collateral;

         (e) take control of any proceeds of the Collateral; and

         (f) execute (in the name, place and stead of Pledgor) endorsements,
         assignments, stock powers and other instruments of conveyance or
         transfer with respect to all or any of the Collateral.




<PAGE>   47


         SECTION 11.2 Attorney-in-Fact. Pledgor hereby irrevocably appoints the
Secured Party its attorney-in-fact, with full authority in the place and stead
of Pledgor and in the name of Pledgor, the Secured Party, or otherwise, from
time to time in the Secured Party's discretion, to take any action and to
execute any instrument which the Secured Party may deem necessary or advisable
to accomplish the purposes of this Agreement, including, upon the occurrence and
continuance of an Event of Default, all actions described in Section 5.1.

         SECTION 11.3 Private Sales.

         (a) Pledgor recognizes that the Secured Party may be unable to effect a
         public sale of any or all the Pledged Shares by reason of certain
         prohibitions contained in the Securities Act of 1933, as amended (the
         "Securities Act") and applicable state securities laws or otherwise,
         and may be compelled to resort to one or more private sales thereof to
         a restricted group of purchasers that will be obliged to agree, among
         other things, to acquire such securities for their own account for
         investment and not with a view to the distribution or resale thereof.
         Pledgor acknowledges and agrees that any such private sale may result
         in prices and other terms less favorable than if such sale were a
         public sale and, notwithstanding such circumstances, agrees that any
         such private sale shall be deemed to have been made in a commercially
         reasonable manner. The Secured Party shall be under no obligation to
         delay sale of any of the Pledged Shares for the period of time
         necessary to permit the Pledgor to register such securities for public
         sale under the Securities Act, or under applicable state securities
         laws, even if Deli-Bon would agree to do so.

         (b) Pledgor further agrees to use its best efforts to do or cause to be
         done all such acts as may be necessary to make such sale or sales of
         all or any portion of the Pledged Shares pursuant to this Section 5.3
         valid and binding and in compliance with any and all other applicable
         requirements of law.

         SECTION 11.4 Application of Proceeds. All cash proceeds received by the
Secured Party in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral may, in the discretion of the Secured
Party, be held by the Secured Party as additional collateral security for, or
then or at any time thereafter be applied in whole or in part by the Secured
Party against, all or any part of the Secured Obligations in the following
order:

         (a) first, Ratably, to the principal then due on the 30 Day Note;

         (b) second, Ratably, to the principal then due on the 60 Day Note;

         (c) third, Ratably, to the unpaid interest accrued and then due on the
         5 Year Note (including any premium thereon); and

         (d) fourth, to any other Secured Obligations then due or owing.

Any surplus of such cash or cash proceeds held by the Secured Party and
remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.



<PAGE>   48



         SECTION 11.5 Indemnity and Expenses. Pledgor hereby indemnifies and
holds harmless the Secured Party from and against any and all claims, losses,
and liabilities growing out of or resulting from this Agreement (including
enforcement of this Agreement), except claims, losses, or liabilities resulting
from the Secured Party's gross negligence or wilful misconduct. Upon demand,
Pledgor will pay, or cause to be paid, to the Secured Party the amount of any
and all reasonable expenses, including the reasonable fees and disbursements of
its counsel and of any experts and agents, which the Secured Party may incur in
connection with:

         (a) the administration of this Agreement;

         (b) the custody, preservation, use, or operation of, or the sale of,
         collection from, or other realization upon, any of the Collateral;

         (c) the exercise or enforcement of any of the rights of the Secured
         Party hereunder and any action taken by the Secured Party under Section
         6.5; or

         (d) the failure by Pledgor to perform or observe any of the provisions
         hereof.

                                   ARTICLE 12

                                  MISCELLANEOUS

         SECTION 12.1 Amendments, etc. No amendment or waiver of any provision
of this Agreement nor consent to any departure by Pledgor herefrom shall in any
event be effective unless the same shall be in writing, signed by the Secured
Party and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it is given.

         SECTION 12.2 Obligations Not Affected. The obligations of Pledgor under
this Agreement shall remain in full force and effect without regard to, and
shall not be impaired or affected by:

         (a) any amendment or modification or addition or supplement to the
         Purchase Agreement, any other Loan Document, any instrument delivered
         in connection therewith or any assignment or transfer thereof;

         (b) any exercise, non-exercise or waiver by the Secured Party of any
         right, remedy, power or privilege under or in respect of, or any
         release of any guaranty or collateral provided pursuant to this
         Agreement, the Purchase Agreement or any Loan Document;

         (c) any waiver, consent, extension, indulgence or other action or
         inaction in respect of this Agreement, the Purchase Agreement or any
         Loan Document or any assignment or transfer of any thereof; or

         (d) any bankruptcy, insolvency, reorganization, arrangement,
         readjustment, composition, liquidation or the like, death or
         incompetency of the Pledgor or any other Person, whether or not Pledgor
         shall have notice or knowledge of any of the foregoing.



<PAGE>   49



         SECTION 12.3 Protection of Collateral. The Secured Party may from time
to time, at its option, perform any act which Pledgor agrees hereunder to
perform and which Pledgor shall fail to perform after being requested in writing
to so perform (it being understood that no such request need be given after the
occurrence and during the continuance of an Event of Default) and the Secured
Party may from time to time take any other action which the Secured Party
reasonably deems necessary for the maintenance, preservation or protection of
any of the Collateral or of its security interest therein.

         SECTION 12.4 Addresses for Notices. All notices and other
communications provided for hereunder to any party hereto under this Agreement
shall be in writing or by facsimile and addressed or delivered to it at the
address set forth below its signature hereto, or as to any party at such other
address as shall be designated by such party in a written notice to each other
party complying as to delivery with the terms of this Section. Any such notice,
if mailed and properly addressed with postage prepaid, shall be deemed given
seven (7) calendar days after mailing; any notice, if transmitted by facsimile
shall be deemed given when transmitted on a business day (with evidence of
transmission confirmation).

         SECTION 12.5 Governing Law; Jurisdiction.

         (a) THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

         (b) EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY SUBMITS TO THE
JURISDICTION OF ANY TEXAS STATE OR FEDERAL COURT SITTING IN DALLAS, TEXAS IN ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR RELATED DOCUMENT (AND PLEDGOR AGREES THAT SUCH JURISDICTION
WILL BE EXCLUSIVE WITH RESPECT TO CLAIMS BROUGHT BY PLEDGOR AGAINST THE SECURED
PARTY), AND EACH HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH TEXAS STATE OR FEDERAL
COURT. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT IT MAY EFFECTIVELY DO SO, THE DEFENSE OF ANY INCONVENIENT FORUM TO THE
MAINTENANCE OF SUCH ACTION OR PROCEEDING.

         (c) Pledgor hereby irrevocably designates, appoints and empowers C.T.
Corporation System, 350 N. St. Paul Street, Suite 2900, Dallas, Texas 75201, as
its authorized agent to receive, for and on its behalf and on behalf of its
property, service of process in the State of Texas when and as such legal
actions or proceedings may be brought in the courts of the State of Texas or of
the United States of America sitting in Texas, and such service of process shall
be deemed complete upon the date of delivery thereof to such agent whether or
not such agent gives notice thereof to Pledgor, or upon the earliest of any
other date permitted by applicable law. It is understood that a copy of said
process served on such agent will as soon as practicable be forwarded to
Pledgor, at its address set forth below, but Pledgor's failure to receive such
copy shall not affect in any way the service of said process on said agent as
the agent of Pledgor. Pledgor irrevocably consents to the service of process out
of any of the aforementioned courts in any such action or proceeding by the



<PAGE>   50



mailing of the copies thereof by certified mail, return receipt requested,
postage prepaid, to Pledgor at its address set forth below, such service to
become effective upon the earlier of (i) the date 10 calendar days after such
mailing or (ii) any earlier date permitted by applicable law. Pledgor agrees
that it will at all times continuously maintain an agent to receive service of
process in the State of Texas and in the event that, for any reason, the agent
named above or its successor shall no longer serve as its agent to receive
service of process in the State of Texas on its behalf, it shall promptly
appoint a successor so to serve and shall advise the Secured Party. Nothing in
this Section 6.5 shall affect the right of the Secured Party to bring
proceedings against Pledgor in the courts of any other jurisdiction or to serve
process in any other manner permitted by applicable law.

         SECTION 12.6 Waiver of Jury Trial. Etc. THE SECURED PARTY, AND PLEDGOR
HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE SECURED PARTY OR PLEDGOR. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE SECURED PARTY'S ENTERING INTO THE
PURCHASE AGREEMENT.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first above written.

                               30 DAY SECURED NOTE

$400,000 (U.S.)                    Dallas, Texas                October 11, 1999


         FOR VALUE RECEIVED, the undersigned, Francois Gravil - Guy Picard, in
trust for the company to be owned and operated by Francois Gravil and Guy Picard
("Maker"), promises to pay to the order of The UniMark Group, Inc., a Texas
corporation ("Payee"), whose principal office is located at 124 McMakin Road,
Bartonville, Texas 76226, the principal sum of Four Hundred Thousand Dollars
($400,000), payable as provided herein, without interest.

         The principal shall be due and payable by the Maker to the Payee on
November 10, 1999 (30 days from October 11, 1999).

         Principal under this Note, or any portion thereof, may be prepaid
without penalty.

         This Note is issued and delivered under and in subject to the terms and
provisions of that certain Stock Purchase Agreement (the "Stock Purchase
Agreement") dated of even date herewith, by and among Payee and Maker. This Note
is secured by a Short-term Pledge Agreement and a Long-term Pledge Agreement
(collectively, the "Pledge Agreements"), each dated October 11, 1999, executed
by the undersigned in favor of the holder hereto, covering all of the issued and
outstanding shares of capital stock of Les Produits Deli-Bon, Inc., a Quebec
corporation ("Deli-Bon") more fully described in Exhibit A hereto attached
hereto (the "Deli-Bon Shares"). Reference is made to the Pledge Agreements for a
statement of the rights and obligations of the Payee, a description of the
nature and extent of the security and the rights of the parties in respect to
such security.

         Maker, and any endorser or guarantors of this Note and all other
persons who may become liable for all or any part of the obligations represented
by this Note, severally waive presentment for payment, protest, notice of
protest and of nonpayment, notice of intention to accelerate, and notice of
acceleration.

          The following shall constitute Events of Default ("Event(s) of
Default"):

                  (a) default in the due and punctual payment of the principal
         of the Note when and as such payment shall become due and payable,
         whether at maturity or by acceleration or otherwise if such payment is
         not made within ten (10) days of written notice mailed by Payee to
         Maker; or

                  (b) default in the performance or observance of any covenant
         or agreement of Maker in this Note or the Pledge Agreements other than
         as described in paragraph (a) above and the continuance of such default
         for a period of seven (7) days after the Payee has sent Maker written
         notice specifying such default and requiring that it be remedied,
         provided that no such default shall be deemed to occur if such default
         may not be cured within seven (7) days, if within said period the Maker
         has commenced and thereafter diligently and


<PAGE>   2



         continuously pursues to cure such default, and the default is cured, in
         any event, within fourteen (14) days; or

                  (c) the filing by the Maker of a petition instituting any
         state or federal insolvency, bankruptcy, reorganization, arrangement,
         composition, or other debtor relief proceeding; the petition of or
         application to any tribunal for a receiver or trustee for itself or for
         any substantial part of any of its property; or

                  (d) the sale or transfer of all or substantially all of the
         assets of Deli-Bon or Maker.

         If an Event of Default occurs, then and in any such case Payee may
declare the outstanding principal amount of the Note to be due and payable
immediately, upon written notice to the Maker, and, upon any such declaration,
the outstanding principal amount of the Note, together with all costs of
collection, including reasonable attorneys' fees if collected by law or through
an attorney at law, shall immediately become due and payable.

         Not withstanding anything to the contrary contained herein, no
provisions of this Note shall require the payment or permit the collection of
interest in excess of the maximum rate permitted by applicable law. If any
interest in excess of such maximum rate is herein provided for, or shall be
adjudicated to be so provided, in this Note or otherwise in connection with this
transaction giving rise to the execution hereof, the provisions of this
paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of the Maker shall be obligated to pay the
excess amount of such interest or any other excess sum paid for the use,
forbearance or detention of sums loaned pursuant hereto. If for any reason
interest in excess of the maximum rate of interest permitted by applicable law
shall be deemed, charged, required or permitted by a court of competent
jurisdiction, any such excess shall be applied as a payment and reduction of the
principal of indebtedness evidenced by this Note; and, if the principal amount
hereof has been paid in full, any remaining excess shall forthwith be paid to
Maker.

         This note is made and is performable in Bartonville, Denton County,
Texas, and Maker waives the right to be sued hereon elsewhere. This Note shall

         FOR VALUE RECEIVED, the undersigned, Francois Gravil - Guy Picard, in
trust for the company to be owned and operated by Francois Gravil and Guy
Picard ("Maker"), promises to pay to the order of The UniMark Group, Inc., a
Texas corporation ("Payee"), whose principal office is located at 124 McMakin
Road, Bartonville, Texas 76226, the principal sum of Four Hundred Thousand
Dollars ($400,000), payable as provided herein, without interest.

         The principal shall be due and payable by the Maker to the Payee on
December 10, 1999 (60 days from October 11, 1999).

         Principal under this Note, or any portion thereof, may be prepaid
without penalty.

         This Note is issued and delivered under and in subject to the terms
and provisions of that certain Stock Purchase Agreement (the "Stock Purchase
Agreement") dated of even date herewith, by and among Payee and Maker. This
Note is secured by a Short-term Pledge Agreement and a Long-term Pledge
Agreement (collectively, the "Pledge Agreements"), each dated October 11, 1999,
executed by the undersigned in favor of the holder hereto, covering all of the
issued and outstanding shares of capital stock of Les Produits Deli-Bon, Inc.,
a Quebec corporation ("Deli-Bon") more fully described in Exhibit A hereto
attached hereto (the "Deli-Bon Shares"). Reference is made to the Pledge
Agreements for a statement of the rights and obligations of the Payee, a
description of the nature and extent of the security and the rights of the
parties in respect to such security.

         Maker, and any endorser or guarantors of this Note and all other
persons who may become liable for all or any part of the obligations
represented by this Note, severally waive presentment for payment, protest,
notice of protest and of nonpayment, notice of intention to accelerate, and
notice of acceleration.

          The following shall constitute Events of Default ("Event(s) of
Default"):

                  (a) default in the due and punctual payment of the principal
         of the Note, when and as such payment shall become due and payable,
         whether at maturity or by acceleration or otherwise if such payment is
         not made within ten (10) days of written notice mailed by Payee to
         Maker; or

                  (b) default in the performance or observance of any covenant
         or agreement of Maker in this Note or the Pledge Agreements other than
         as described in paragraph (a) above and the continuance of such
         default for a period of seven (7) days after the Payee has sent Maker
         written notice specifying such default and requiring that it be
         remedied, provided that no such default shall be deemed to occur if
         such default may not be cured within seven (7) days, if within said
         period the Maker has commenced and thereafter diligently and



<PAGE>   2

         continuously pursues to cure such default, and the default is cured,
         in any event, within fourteen (14) days; or

                  (c) the filing by the Maker of a petition instituting any
         state or federal insolvency, bankruptcy, reorganization, arrangement,
         composition, or other debtor relief proceeding; the petition of or
         application to any tribunal for a receiver or trustee for itself or
         for any substantial part of any of its property; or

                  (d) the sale or transfer of all or substantially all of the
         assets of Deli-Bon or Maker.

         If an Event of Default occurs, then and in any such case Payee may
declare the outstanding principal amount of the Note to be due and payable
immediately, upon written notice to the Maker, and, upon any such declaration,
the outstanding principal amount of the Note, together with all costs of
collection, including reasonable attorneys' fees if collected by law or through
an attorney at law, shall immediately become due and payable.

         Not withstanding anything to the contrary contained herein, no
provisions of this Note shall require the payment or permit the collection of
interest in excess of the maximum rate permitted by applicable law. If any
interest in excess of such maximum rate is herein provided for, or shall be
adjudicated to be so provided, in this Note or otherwise in connection with
this transaction giving rise to the execution hereof, the provisions of this
paragraph shall govern and prevail, and neither Maker nor the sureties,
guarantors, successors or assigns of the Maker shall be obligated to pay the
excess amount of such interest or any other excess sum paid for the use,
forbearance or detention of sums loaned pursuant hereto. If for any reason
interest in excess of the maximum rate of interest permitted by applicable law
shall be deemed, charged, required or permitted by a court of competent
jurisdiction, any such excess shall be applied as a payment and reduction of
the principal of indebtedness evidenced by this Note; and, if the principal
amount hereof has been paid in full, any remaining excess shall forthwith be
paid to Maker.

         This note is made and is performable in Bartonville, Denton County,
Texas, and Maker waives the right to be sued hereon elsewhere. This Note shall
be governed by and construed in accordance with the laws of the State of Texas
and the applicable laws of the United States of America.

assigns, charges, mortgages, delivers and transfers to the Secured Party, and
hereby grants to the Secured Party, a continuing security interest in, all of
the following property (the "Collateral"):

         (a)      the Initial Pledged Shares;

         (b)      all Pledged Shares issued from time to time;

         (c)      all other Pledged Property, whether now or hereafter delivered
                  to the Secured Party in connection with this Agreement;

         (d)      all Dividends, Distributions, interest and other payments and
                  rights with respect to any Pledged Property; and

         (e)      all proceeds of any of the foregoing.

         SECTION 2.2 Security for Secured Obligations. This Agreement secures
the payment in full of all obligations of the Pledgor now or hereafter existing

Pledged Shares. In addition, the Secured Party shall have the right at any time
to exchange certificates or instruments representing or evidencing any Pledged

         SECTION 2.4 Continuing Security Interest; Transfer of Note. This
Agreement shall

         (a)      create a continuing security interest in the Collateral;

         (b)      remain in full force and effect until payment in full of all
                  Secured Obligations;

         (c)      be binding upon Pledgor, its successors and assigns; provided
                  that Pledgor may not assign any of its rights or obligations
                  hereunder without the prior written consent of the Secured
                  Party; and

         (d)      inure to the benefit of the Secured Party and their respective
                  successors, transferees and assigns.

Without limiting the foregoing, any holder may assign or otherwise transfer any
other obligation, held by it to any other person, in accordance with the terms
of the Purchase Agreement, and such other person shall thereupon become vested
with all the benefits in respect thereof granted herein, in the other Loan
Documents or otherwise. Upon the payment in full of the Secured Obligations, the
security interest granted herein shall terminate and all rights to the
Collateral shall revert to Pledgor. Upon any such termination, the Secured Party
will, at Pledgor's expense, deliver all certificates and instruments
representing or evidencing all Pledged Shares, together with all other
Collateral held by the Secured Party hereunder, and execute and deliver to
Pledgor (without recourse or representation whatsoever), at Pledgor's expense,
such documents as Pledgor shall reasonably request to evidence such termination.


                                    ARTICLE 3

                         REPRESENTATIONS AND WARRANTIES

         SECTION 3.1 Warranties, etc. Pledgor represents and warrants unto the
Secured Party that as at the date of each pledge hereunder (including each
pledge of Pledged Shares) by Pledgor to the Secured Party of any Collateral,

         (a) Pledgor has all requisite power and authority, and has taken all
         necessary corporate action, to execute and deliver and perform its
         obligations under this Pledge Agreement and to pledge the Collateral
         hereunder.

         (b) The execution, delivery and performance of this Agreement by
         Pledgor, and the pledge of the Collateral hereunder do not and will not
         conflict with, result in any violation of, or constitute any default
         under, any provision of any contractual obligation of Pledgor or any
         law or government regulation or court decree or order and will not
         result in or require the creation or imposition of any lien on any of
         Pledgor's properties pursuant to the provisions of any contractual
         obligation. This Agreement is the legal, valid and binding obligation
         of Pledgor enforceable in accordance with its terms subject to the
         effect of

                           (i) any applicable bankruptcy, insolvency or similar
                  laws affecting creditors' rights generally; and

                                       -4-

<PAGE>   5



                           (ii) general principles of equity (regardless of
                  whether considered in a proceeding in equity or at law).

         (c) Except as disclosed in the Purchase Agreement, there is no pending
         or, to the knowledge of Pledgor, threatened litigation, arbitration or
         governmental investigation, proceeding or inquiry against Pledgor, or
         to which any of its properties, assets or revenues is subject.

         (d) Pledgor will be the legal and beneficial owner of, and will have
         good and marketable title to (and will have full right and authority to
         pledge and assign) all Collateral, free and clear of all liens or other
         charges or encumbrances, except any lien or security interest granted
         pursuant hereto in favor of the Secured Party.

         (e) The delivery of the Collateral (including the delivery of the
         Initial Pledged Shares) to the Secured Party will be effective to
         create a valid, perfected, first priority security interest in such
         Collateral and all proceeds thereof, securing the Secured Obligations,
         and no filing or other action will be necessary to perfect or protect
         such security interest.

         (f) In the case of any Pledged Shares constituting Collateral, all of
         such Pledged Shares will be duly authorized and validly issued, fully
         paid, and non-assessable.

         (g) No authorization, approval, or other action by, and no notice to or
         filing with, any governmental authority will be required either

                           (i) for the pledge by Pledgor of any Collateral
                  pursuant to this Agreement or for the execution, delivery, or
                  performance of this Agreement by Pledgor, or

                           (ii) for the exercise by the Secured Party of the
                  voting or other rights provided for in this Agreement, or
                  (except, with respect to any Pledged Shares, as may be
                  required in connection with a disposition of such Pledged
                  Shares by laws affecting the offering and sale of securities
                  generally) the remedies in respect of the Collateral pursuant
                  to this Agreement.

         SECTION 4.1 Protect Collateral; Further Assurances, etc. Pledgor will
not sell, assign, transfer, pledge or encumber in any other manner the
Collateral (except in favor of the Secured Party hereunder). Pledgor will
warrant and will use its best efforts to defend the right and title herein
granted unto the Secured Party in and to the Collateral (and all right, title
and interest represented by the Collateral) against the claims and demands of
all Persons whomsoever. Pledgor agrees that at any time, and from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments, and take all further action, that may be necessary or desirable, or
that the Secured Party may reasonably request, in order to perfect and protect
any security interest granted

                                       -5-

or purported to be granted hereby or to enable the Secured Party to exercise and
enforce its rights and remedies hereunder with respect to any Collateral.

         SECTION 4.2 Stock Powers, etc. Pledgor agrees that all Pledged Shares
(and all other shares of capital stock constituting Collateral) delivered by
Pledgor pursuant to this Agreement will be accompanied by duly executed undated
blank stock powers, or other equivalent instruments of transfer acceptable to
the Secured Party. Pledgor will, from time to time upon the request of the
Secured Party, promptly deliver to the Secured Party such stock powers,
instruments and similar documents, satisfactory in form and substance to the
Secured Party, with respect to the Collateral as the Secured Party may
reasonably request and will, from time to time upon the request of the Secured
Party after the occurrence of any default, promptly transfer any Pledged Shares
or other shares of stock constituting Collateral into the name of the Secured
Party or any nominee designated by the Secured Party.

         SECTION 4.3 Continuous Pledge. Pledgor will, at all times, keep pledged
to the Secured Party pursuant hereto all Pledged Shares and all other shares of
stock constituting Collateral, all Dividends and Distributions with respect
thereto, and all other Collateral and other securities, instruments, proceeds
and rights from time to time received by or distributable to Pledgor in respect
of any Collateral.

         SECTION 4.4 Voting Rights; Dividends, etc. Pledgor agrees to deliver
all Distributions at any time received by it to the Secured Party to be held as
Collateral hereunder and, in addition, to deliver (properly endorsed where
required hereby or requested by the Secured Party) to the Secured Party:

         (a) after any Default shall have occurred and be continuing or if any
         Default shall occur as a result thereof, promptly upon receipt thereof
         by Pledgor and without any request therefor by the Secured Party, all
         Dividends, all other cash payments and all proceeds of the Collateral,
         all of which shall be held by the Secured Party as additional
         collateral for use in accordance with Section 5.4; and

         (b) after any Default shall have occurred and be continuing, promptly
         upon request of the Secured Party, such proxies and other documents as
         may be necessary to allow the Secured Party to exercise the voting
         power with respect to any share of capital stock constituting
         Collateral;

provided, however, that unless a default shall have occurred and be continuing
or result therefrom, Pledgor shall be entitled to exercise, in its reasonable
judgment, but in a manner not inconsistent with the terms of the Purchase
Agreement or any other Loan Document (including this Agreement), the voting
power and all other incidental rights of ownership with respect to any Pledged
Shares or other shares of capital stock constituting Collateral (subject to
Pledgor's obligation to deliver to the Secured Party such Pledged Shares and
other shares in pledge hereunder).

All Dividends, Distributions, cash payments and proceeds which may at any time
and from time to time be held by Pledgor but which Pledgor is then obligated to
deliver to the Secured Party, shall, until delivery to the Secured Party, be
held by Pledgor separate and apart from its other property in

                                       -6-

trust for the Secured Party. The Secured Party agrees that unless a Default
shall have occurred and be continuing, the Secured Party shall, upon the written
request of Pledgor, promptly deliver such proxies and other documents, if any,
as shall be reasonably requested by Pledgor which are necessary to allow Pledgor
to exercise voting power with respect to any share of capital stock (including
Pledged Shares) constituting Collateral; provided, however that no vote shall be
cast, or consent, waiver or ratification given, or action taken by Pledgor that
would impair any Collateral or be inconsistent with or violate any provision of
the Purchase Agreement or any other Loan Document (including this Agreement).

         SECTION 4.5 Sale of Assets. Pledgor will not sell, assign, transfer,
pledge or encumber all or substantially all of the assets that are necessary for
the operations of Deli-Bon as presently conducted.

         SECTION 4.6 Payment of the Obligations. The Pledgor will pay each part

         SECTION 4.7 Agreements. Pledgor will comply with and duly and
punctually perform and observe all agreements, covenants, and obligations
contained in the Loan Documents and any other agreement between it and the
Secured Party.

         SECTION 4.8 Books and Records; Inspection. Pledgor will maintain in a
secure place on the Pledgor's premises, complete proper and accurate books,
records, ledgers, correspondence, and other papers relating to Deli-Bon's
business and affairs. The Secured Party will at all reasonable times have the
right to examine, inspect, audit, verify, and copy such items, and to remove
copies thereof and to discuss any of same with appropriate officers,
accountants, and auditors of Pledgor.

         SECTION 4.9 Notice of Default. Within twenty-four (24) hours of the
discovery by Pledgor of the occurrence of a Default or Event of Default
hereunder or under any of the other Transaction Documents or an event which
could reasonably be expected to result in a Default or Event of Default
hereunder or under any other Loan Document, the Pledgor will notify the Secured
Party and will deliver a certificate signed by the president, chief executive
officer or the chief financial officer of the Pledgor concerning the nature and
period of existence thereof and the steps, if any, being taken to cure such
Default or Event of Default.

         SECTION 4.10 Maintenance of Existence, Approvals, and Licenses. Pledgor
will preserve and maintain Deli-Bon's existence, rights, privileges, operations
and franchises in its jurisdiction of creation, qualify and remain qualified in
each jurisdiction in which, under then applicable law, the nature of its
business or the ownership of its properties requires such qualification and
obtain and maintain in full force all approvals, licenses (governmental and
private) permits, and authorizations necessary to conduct its business and
comply with its obligations under the Loan Documents. Pledgor will continue to
operate Deli-Bon in a prudent and businesslike manner.

         SECTION 4.11 Compliance with Laws, Material Agreements, and Licenses.
Pledgor will comply with all foreign and domestic laws, rules, regulations,
ordinances, orders, judgments, and decrees applicable to it or any of its
property, a breach of which (when considered alone or when aggregated with the
effect of other breaches) could have a material adverse effect, will comply in
all

                                       -7-

respects with all material agreements, indentures, mortgages, leases, and other
documents to which it is a party or by which it or any of its property is bound
and will keep in full force and effect all material licenses, permits, and
franchises necessary or useful for the conduct of its business.

         SECTION 4.12 Maintenance of Assets and Insurance. Pledgor will keep all
assets which are useful and necessary in the business in good working order and
condition, make all necessary replacements and maintain, or cause to be
maintained, such insurance as is customarily maintained by other businesses of
comparable type and size with such financially sound and reputable insurers, in
such amounts and covering such risks as shall be satisfactory and acceptable to
the Secured Party.

         SECTION 4.13 Financial Information. Pledgor will furnish to the Secured
Party with seven (7) days (a) such financial information and information
regarding Payee and Deli-Bon as the Secured Party may from time to time
reasonably request and (b) written notice of the occurrence of any event which
would make any representation contained in Article III untrue at such time.


                                    ARTICLE 5

                                    REMEDIES

         SECTION 5.1 Actions upon Event of Default. In addition to its rights
and remedies provided hereunder, whenever an Event of Default shall have
occurred and be continuing, the Secured Party shall have all rights and remedies
of a secured party upon default under the U.C.C. or other applicable law. Any
notification required by law of any intended disposition by the Secured Party of
any of the Collateral shall be deemed reasonably and properly given if given at
least 15 days before such disposition. Without limitation of the above, the
secured Party may, whenever an Event of Default shall have occurred and be
continuing, without prior notice to Pledgor, take all or any of the following
actions:

         (a) transfer all or any part of the Collateral into the name of the
         Secured Party or its nominee, with or without disclosing that such
         Collateral is subject to the lien and security interest hereunder;

         (b) notify the parties obligated on any of the Collateral to make
         payment to the Secured Party of any amount due or to become due
         thereunder;

         (c) enforce collection of any of the Collateral by suit or otherwise,
         and surrender, release or exchange all or any part thereof, or
         compromise or extend or renew for any period (whether or not longer
         than the original period) any obligations of any nature of any party
         with respect thereto;

         (d) endorse any checks, drafts, or other writings in Pledgor's name to
         allow collection of the Collateral;

         (e) take control of any proceeds of the Collateral; and


                                       -8-

<PAGE>   9



         (f) execute (in the name, place and stead of Pledgor) endorsements,
         assignments, stock powers and other instruments of conveyance or
         transfer with respect to all or any of the Collateral.

         SECTION 5.2 Attorney-in-Fact. Pledgor hereby irrevocably appoints the
Secured Party its attorney-in-fact, with full authority in the place and stead
of Pledgor and in the name of Pledgor, the Secured Party, or otherwise, from
time to time in the Secured Party's discretion, to take any action and to
execute any instrument which the Secured Party may deem necessary or advisable
to accomplish the purposes of this Agreement, including, upon the occurrence and
continuance of an Event of Default, all actions described in Section 5.1.

         SECTION 5.3                Private Sales.

         (a) Pledgor recognizes that the Secured Party may be unable to effect a
         public sale of any or all the Pledged Shares by reason of certain
         prohibitions contained in the Securities Act of 1933, as amended (the
         "Securities Act") and applicable state securities laws or otherwise,
         and may be compelled to resort to one or more private sales thereof to
         a restricted group of purchasers that will be obliged to agree, among
         other things, to acquire such securities for their own account for
         investment and not with a view to the distribution or resale thereof.
         Pledgor acknowledges and agrees that any such private sale may result
         in prices and other terms less favorable than if such sale were a
         public sale and, notwithstanding such circumstances, agrees that any
         such private sale shall be deemed to have been made in a commercially
         reasonable manner. The Secured Party shall be under no obligation to
         delay sale of any of the Pledged Shares for the period of time
         necessary to permit the Pledgor to register such securities for public
         sale under the Securities Act, or under applicable state securities
         laws, even if Deli-Bon would agree to do so.

         (b) Pledgor further agrees to use its best efforts to do or cause to be
         done all such acts as may be necessary to make such sale or sales of
         all or any portion of the Pledged Shares pursuant to this Section 5.3
         valid and binding and in compliance with any and all other applicable
         requirements of law.

         SECTION 5.4 Application of Proceeds. All cash proceeds received by the
Secured Party in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral may, in the discretion of the Secured
Party, be held by the Secured Party as additional collateral security for, or
then or at any time thereafter be applied in whole or in part by the Secured
Party against, all or any part of the Secured Obligations in the following
order:

         (a)     first, Ratably, to the principal then due on the 30 Day Note;

         (b)     second, Ratably, to the  principal then due on the 60 Day Note;

         (c)     third, to any other Secured Obligations then due or owing.


                                       -9-

<PAGE>   10



Any surplus of such cash or cash proceeds held by the Secured Party and
remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.

         SECTION 5.5 Indemnity and Expenses. Pledgor hereby indemnifies and
holds harmless the Secured Party from and against any and all claims, losses,
and liabilities growing out of or resulting from this Agreement (including
enforcement of this Agreement), except claims, losses, or liabilities resulting
from the Secured Party's gross negligence or wilful misconduct. Upon demand,
Pledgor will pay, or cause to be paid, to the Secured Party the amount of any
and all reasonable expenses, including the reasonable fees and disbursements of
its counsel and of any experts and agents, which the Secured Party may incur in
connection with:

         (a) the administration of this Agreement;

         (b) the custody, preservation, use, or operation of, or the sale of,
         collection from, or other realization upon, any of the Collateral;

         (c) the exercise or enforcement of any of the rights of the Secured
         Party hereunder and any action taken by the Secured Party under Section
         6.5; or

         (d) the failure by Pledgor to perform or observe any of the provisions
         hereof.


                                    ARTICLE 6

                                  MISCELLANEOUS

         SECTION 6.1 Amendments, etc. No amendment or waiver of any provision of
this Agreement nor consent to any departure by Pledgor herefrom shall in any
event be effective unless the same shall be in writing, signed by the Secured
Party and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it is given.

         SECTION 6.2 Obligations Not Affected. The obligations of Pledgor under
this Agreement shall remain in full force and effect without regard to, and
shall not be impaired or affected by:

         (a) any amendment or modification or addition or supplement to the
         Purchase Agreement, any other Loan Document, any instrument delivered
         in connection therewith or any assignment or transfer thereof;

         (b) any exercise, non-exercise or waiver by the Secured Party of any
         right, remedy, power or privilege under or in respect of, or any
         release of any guaranty or collateral provided pursuant to this
         Agreement, the Purchase Agreement or any Loan Document;

         (c) any waiver, consent, extension, indulgence or other action or
         inaction in respect of this Agreement, the Purchase Agreement or any
         Loan Document or any assignment or transfer of any thereof; or


                                      -10-

<PAGE>   11



         (d) any bankruptcy, insolvency, reorganization, arrangement,
         readjustment, composition, liquidation or the like, death or
         incompetency of the Pledgor or any other Person, whether or not Pledgor
         shall have notice or knowledge of any of the foregoing.

         SECTION 6.3 Protection of Collateral. The Secured Party may from time
to time, at its option, perform any act which Pledgor agrees hereunder to
perform and which Pledgor shall fail to perform after being requested in writing
to so perform (it being understood that no such request need be given after the
occurrence and during the continuance of an Event of Default) and the Secured
Party may from time to time take any other action which the Secured Party
reasonably deems necessary for the maintenance, preservation or protection of
any of the Collateral or of its security interest therein.

         SECTION 6.4 Addresses for Notices. All notices and other communications
provided for hereunder to any party hereto under this Agreement shall be in
writing or by facsimile and addressed or delivered to it at the address set
forth below its signature hereto, or as to any party at such other address as
shall be designated by such party in a written notice to each other party
complying as to delivery with the terms of this Section. Any such notice, if
mailed and properly addressed with postage prepaid, shall be deemed given seven
(7) calendar days after mailing; any notice, if transmitted by facsimile shall

         (b)      The execution, delivery and performance of this Agreement by
         Pledgor, and the pledge of the Collateral hereunder do not and will not
         conflict with, result in any violation of, or constitute any default
         under, any provision of any contractual obligation of Pledgor or any

         good and marketable title to (and will have full right and authority to
         pledge and assign) all Collateral, free and clear of all liens or other
         charges or encumbrances, except any lien or security interest granted

         and no filing or other action will be necessary to perfect or protect
         such security interest.

                  pursuant to this Agreement or for the execution, delivery, or
                  performance of this Agreement by Pledgor, or

                           (ii) for the exercise by the Secured Party of the
                  voting or other rights provided for in this Agreement, or
                  (except, with respect to any Pledged Shares, as may be
                  required in connection with a disposition of such Pledged
                  Shares by laws affecting the offering and sale of securities
                  generally) the remedies in respect of the Collateral pursuant

         SECTION 4.1 Protect Collateral; Further Assurances. etc. Pledgor will
not sell, assign, transfer, pledge or encumber in any other manner the
Collateral (except in favor of the Secured Party hereunder). Pledgor will
warrant and will use its best efforts to defend the right and title herein
granted unto the Secured Party in and to the Collateral (and all right, title
and interest represented by the Collateral) against the claims and demands of
all Persons whomsoever. Pledgor agrees that at any time, and from time to time,
at the expense of Pledgor, Pledgor will promptly execute and deliver all further
instruments, and take all further action, that may be necessary or desirable, or
that the Secured Party may reasonably request, in order to perfect and protect
any security interest granted or purported to be granted hereby or to enable the
Secured Party to exercise and enforce its rights and remedies hereunder with
respect to any Collateral.

         SECTION 4.2 Stock Powers, etc. Pledgor agrees that all Pledged Shares
(and all other shares of capital stock constituting Collateral) delivered by
Pledgor pursuant to this Agreement will be


                                       -5-

accompanied by duly executed undated blank stock powers, or other equivalent
instruments of transfer acceptable to the Secured Party. Pledgor will, from time
to time upon the request of the Secured Party, promptly deliver to the Secured
Party such stock powers, instruments and similar documents, satisfactory in form
and substance to the Secured Party, with respect to the Collateral as the
Secured Party may reasonably request and will, from time to time upon the
request of the Secured Party after the occurrence of any default, promptly
transfer any Pledged Shares or other shares of stock constituting Collateral
into the name of the Secured Party or any nominee designated by the Secured
Party.

         SECTION 4.3 Continuous Pledge. Pledgor will, at all times, keep pledged
to the Secured Party pursuant hereto all Pledged Shares and all other shares of
stock constituting Collateral, all Dividends and Distributions with respect
thereto, and all other Collateral and other securities, instruments, proceeds
and rights from time to time received by or distributable to Pledgor in respect
of any Collateral.

         SECTION 4.4 Voting Rights; Dividends, etc. Pledgor agrees to deliver
all Distributions at any time received by it to the Secured Party to be held as
Collateral hereunder and, in addition, to deliver (properly endorsed where
required hereby or requested by the Secured Party) to the Secured Party:

         (a) after any Default shall have occurred and be continuing or if any
         Default shall occur as a result thereof, promptly upon receipt thereof
         by Pledgor and without any request therefor by the Secured Party, all
         Dividends, all other cash payments and all proceeds of the Collateral,
         all of which shall be held by the Secured Party as additional
         collateral for use in accordance with Section 5.4; and

         (b) after any Default shall have occurred and be continuing, promptly
         upon request of the Secured Party, such proxies and other documents as
         may be necessary to allow the Secured Party to exercise the voting
         power with respect to any share of capital stock constituting
         Collateral;

provided, however, that unless a default shall have occurred and be continuing
or result therefrom, Pledgor shall be entitled to exercise, in its reasonable
judgment, but in a manner not inconsistent with the terms of the Purchase
Agreement or any other Loan Document (including this Agreement), the voting
power and all other incidental rights of ownership with respect to any Pledged
Shares or other shares of capital stock constituting Collateral (subject to
Pledgor's obligation to deliver to the Secured Party such Pledged Shares and
other shares in pledge hereunder).

All Dividends, Distributions, cash payments and proceeds which may at any time
and from time to time be held by Pledgor but which Pledgor is then obligated to
deliver to the Secured Party, shall, until delivery to the Secured Party, be
held by Pledgor separate and apart from its other property in trust for the
Secured Party. The Secured Party agrees that unless a Default shall have
occurred and be continuing, the Secured Party shall, upon the written request of
Pledgor, promptly deliver such proxies and other documents, if any, as shall be
reasonably requested by Pledgor which are necessary to allow Pledgor to exercise
voting power with respect to any share of capital stock (including Pledged
Shares) constituting Collateral; provided, however that no vote shall be cast,
or consent,

Agreement or any other Loan Document (including this Agreement).

punctually perform and observe all agreements, covenants, and obligations

Secured Party.

         SECTION 4.8 Books and Records; Inspection. Pledgor will maintain in a
secure place on the Pledgor's premises, complete proper and accurate books,
records, ledgers, correspondence, and other papers relating to Deli-Bon's
business and affairs. The Secured Party will at all reasonable times have the
right to examine, inspect, audit, verify, and copy such items, and to remove
copies thereof and to discuss any of same with appropriate officers,
accountants, and auditors of Pledgor.

         SECTION 4.9 Notice of Default. Within twenty-four (24) hours of the
discovery by Pledgor of the occurrence of a Default or Event of Default
hereunder or under any of the other Transaction Documents or an event which

operate Deli-Bon in a prudent and businesslike manner.

         SECTION 4.11 Compliance with Laws, Material Agreements, and Licenses.
Pledgor will comply with all foreign and domestic laws, rules, regulations,
ordinances, orders, judgments, and decrees applicable to it or any of its
property, a breach of which (when considered alone or when aggregated with the

all respects with all material agreements, indentures, mortgages, leases, and
other documents to which it is a party or by which it or any of its property is
bound and will keep in full force and effect all material licenses, permits, and

         SECTION 4.12 Maintenance of Assets and Insurance. Pledgor will keep all
assets which are useful and necessary in the business in good working order and
condition, make all necessary replacements and maintain, or cause to be

comparable type and size with such financially sound and reputable insurers, in
such amounts and covering such risks as shall be satisfactory and acceptable to

         SECTION 4.13 Financial Information. Pledgor will furnish to the Secured
Party within seven (7) days (a) such financial information and information
regarding Payee and Deli-Bon as the Secured Party may from time to time

would make any representation contained in Article III untrue at such time.


                                    ARTICLE 5

                                    REMEDIES

         SECTION 5.1 Actions upon Event of Default. In addition to its rights
and remedies provided hereunder, whenever an Event of Default shall have
occurred and be continuing, the Secured Party shall have all rights and remedies
of a secured party upon default under the U.C.C. or other applicable law. Any
notification required by law of any intended disposition by the Secured Party of
any of the Collateral shall be deemed reasonably and properly given if given at
least 15 days before such disposition. Without limitation of the above, the
secured Party may, whenever an Event of Default shall have occurred and be
continuing, without prior notice to Pledgor, take all or any of the following
actions:

         (a) transfer all or any part of the Collateral into the name of the
         Secured Party or its nominee, with or without disclosing that such
         Collateral is subject to the lien and security interest hereunder;

         (b) notify the parties obligated on any of the Collateral to make
         payment to the Secured Party of any amount due or to become due
         thereunder;

         (c) enforce collection of any of the Collateral by suit or otherwise,
         and surrender, release or exchange all or any part thereof, or
         compromise or extend or renew for any period (whether or not longer
         than the original period) any obligations of any nature of any party
         with respect thereto;

         (d) endorse any checks, drafts, or other writings in Pledgor's name to
         allow collection of the Collateral;

         (e) take control of any proceeds of the Collateral; and

         (f) execute (in the name, place and stead of Pledgor) endorsements,
         assignments, stock powers and other instruments of conveyance or
         transfer with respect to all or any of the Collateral.

<PAGE>   9



         SECTION 5.2 Attorney-in-Fact. Pledgor hereby irrevocably appoints the
Secured Party its attorney-in-fact, with full authority in the place and stead
of Pledgor and in the name of Pledgor, the Secured Party, or otherwise, from
time to time in the Secured Party's discretion, to take any action and to
execute any instrument which the Secured Party may deem necessary or advisable
to accomplish the purposes of this Agreement, including, upon the occurrence and
continuance of an Event of Default, all actions described in Section 5.1.

         SECTION 5.3 Private Sales.

         (a) Pledgor recognizes that the Secured Party may be unable to effect a
         public sale of any or all the Pledged Shares by reason of certain
         prohibitions contained in the Securities Act of 1933, as amended (the
         "Securities Act") and applicable state securities laws or otherwise,
         and may be compelled to resort to one or more private sales thereof to
         a restricted group of purchasers that will be obliged to agree, among
         other things, to acquire such securities for their own account for
         investment and not with a view to the distribution or resale thereof.
         Pledgor acknowledges and agrees that any such private sale may result
         in prices and other terms less favorable than if such sale were a
         public sale and, notwithstanding such circumstances, agrees that any
         such private sale shall be deemed to have been made in a commercially
         reasonable manner. The Secured Party shall be under no obligation to
         delay sale of any of the Pledged Shares for the period of time
         necessary to permit the Pledgor to register such securities for public
         sale under the Securities Act, or under applicable state securities
         laws, even if Deli-Bon would agree to do so.

         (b) Pledgor further agrees to use its best efforts to do or cause to be
         done all such acts as may be necessary to make such sale or sales of
         all or any portion of the Pledged Shares pursuant to this Section 5.3
         valid and binding and in compliance with any and all other applicable
         requirements of law.

         SECTION 5.4 Application of Proceeds. All cash proceeds received by the
Secured Party in respect of any sale of, collection from, or other realization
upon, all or any part of the Collateral may, in the discretion of the Secured
Party, be held by the Secured Party as additional collateral security for, or
then or at any time thereafter be applied in whole or in part by the Secured
Party against, all or any part of the Secured Obligations in the following
order:

         (a) first, Ratably, to the principal then due on the 30 Day Note;

         (b) second, Ratably, to the principal then due on the 60 Day Note;

         (c) third, Ratably, to the unpaid interest accrued and then due on the
         5 Year Note (including any premium thereon); and

         (d) fourth, to any other Secured Obligations then due or owing.

Any surplus of such cash or cash proceeds held by the Secured Party and
remaining after payment in full of all the Secured Obligations shall be paid
over to Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.

         SECTION 5.5 Indemnity and Expenses. Pledgor hereby indemnifies and
holds harmless the Secured Party from and against any and all claims, losses,
and liabilities growing out of or resulting from this Agreement (including
enforcement of this Agreement), except claims, losses, or liabilities resulting
from the Secured Party's gross negligence or wilful misconduct. Upon demand,
Pledgor will pay, or cause to be paid, to the Secured Party the amount of any
and all reasonable expenses, including the reasonable fees and disbursements of
its counsel and of any experts and agents, which the Secured Party may incur in
connection with:

         (a) the administration of this Agreement;

         (b) the custody, preservation, use, or operation of, or the sale of,
         collection from, or other realization upon, any of the Collateral;

         (c) the exercise or enforcement of any of the rights of the Secured
         Party hereunder and any action taken by the Secured Party under Section
         6.5; or

         (d) the failure by Pledgor to perform or observe any of the provisions
         hereof.


                                    ARTICLE 6

                                  MISCELLANEOUS

         SECTION 6.1 Amendments, etc. No amendment or waiver of any provision of
this Agreement nor consent to any departure by Pledgor herefrom shall in any
event be effective unless the same shall be in writing, signed by the Secured
Party and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it is given.

         SECTION 6.2 Obligations Not Affected. The obligations of Pledgor under
this Agreement shall remain in full force and effect without regard to, and
shall not be impaired or affected by:

         (a) any amendment or modification or addition or supplement to the
         Purchase Agreement, any other Loan Document, any instrument delivered
         in connection therewith or any assignment or transfer thereof;

         (b) any exercise, non-exercise or waiver by the Secured Party of any
         right, remedy, power or privilege under or in respect of, or any
         release of any guaranty or collateral provided pursuant to this
         Agreement, the Purchase Agreement or any Loan Document;

         (c) any waiver, consent, extension, indulgence or other action or
         inaction in respect of this Agreement, the Purchase Agreement or any
         Loan Document or any assignment or transfer of any thereof; or

         (d) any bankruptcy, insolvency, reorganization, arrangement,
         readjustment, composition, liquidation or the like, death or
         incompetency of the Pledgor or any other Person, whether or not Pledgor
         shall have notice or knowledge of any of the foregoing.


                                      -10-

<PAGE>   11



         SECTION 6.3 Protection of Collateral. The Secured Party may from time
to time, at its option, perform any act which Pledgor agrees hereunder to
perform and which Pledgor shall fail to perform after being requested in writing
to so perform (it being understood that no such request need be given after the
occurrence and during the continuance of an Event of Default) and the Secured
Party may from time to time take any other action which the Secured Party
reasonably deems necessary for the maintenance, preservation or protection of
any of the Collateral or of its security interest therein.

         SECTION 6.4 Addresses for Notices. All notices and other communications
provided for hereunder to any party hereto under this Agreement shall be in
writing or by facsimile and addressed or delivered to it at the address set
forth below its signature hereto, or as to any party at such other address as
shall be designated by such party in a written notice to each other party
complying as to delivery with the terms of this Section. Any such notice, if
mailed and properly addressed with postage prepaid, shall be deemed given seven
(7) calendar days after mailing; any notice, if transmitted by facsimile shall
be deemed given when transmitted on a business day (with evidence of

         SECTION 6.5 Governing Law; Jurisdiction.

         (a) THIS AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

         (b) EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY SUBMITS TO THE
JURISDICTION OF ANY TEXAS STATE OR FEDERAL COURT SITTING IN DALLAS, TEXAS IN ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT OR RELATED DOCUMENT (AND PLEDGOR AGREES THAT SUCH JURISDICTION
WILL BE EXCLUSIVE WITH RESPECT TO CLAIMS BROUGHT BY PLEDGOR AGAINST THE SECURED
PARTY), AND EACH HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH TEXAS STATE OR FEDERAL
COURT. EACH PARTY TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT IT MAY EFFECTIVELY DO SO, THE DEFENSE OF ANY INCONVENIENT FORUM TO THE
MAINTENANCE OF SUCH ACTION OR PROCEEDING.

         (c) Pledgor hereby irrevocably designates, appoints and empowers C.T.
Corporation System, 350 N. St. Paul Street, Suite 2900, Dallas, Texas 75201, as
its authorized agent to receive, for and on its behalf and on behalf of its
property, service of process in the State of Texas when and as such legal
actions or proceedings may be brought in the courts of the State of Texas or of
the United States of America sitting in Texas, and such service of process shall
be deemed complete upon the date of delivery thereof to such agent whether or
not such agent gives notice thereof to Pledgor, or upon the earliest of any
other date permitted by applicable law. It is understood that a copy of said
process served on such agent will as soon as practicable be forwarded to
Pledgor, at its address set forth below, but Pledgor's failure to receive such
copy shall not affect in any way the service of said process on said agent as
the agent of Pledgor. Pledgor irrevocably consents to the service of process out
of any of the aforementioned courts in any such action or proceeding by the


                                      -11-

mailing of the copies thereof by certified mail, return receipt requested,
postage prepaid, to Pledgor at its address set forth below, such service to
become effective upon the earlier of (i) the date 10 calendar days after such
mailing or (ii) any earlier date permitted by applicable law. Pledgor agrees
that it will at all times continuously maintain an agent to receive service of
process in the State of Texas and in the event that, for any reason, the agent
named above or its successor shall no longer serve as its agent to receive
service of process in the State of Texas on its behalf, it shall promptly
appoint a successor so to serve and shall advise the Secured Party. Nothing in
this Section 6.5 shall affect the right of the Secured Party to bring
proceedings against Pledgor in the courts of any other jurisdiction or to serve
process in any other manner permitted by applicable law.

         SECTION 6.6 Waiver of Jury Trial. Etc. THE SECURED PARTY, AND PLEDGOR
HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR
RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE SECURED PARTY OR PLEDGOR. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE SECURED PARTY'S ENTERING INTO THE
PURCHASE AGREEMENT.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first above written.
