Security Agreement
                        (All Assets)
----------------------- --------------------------------------------------------

As of April 9, 2001, for value received, ZIMMERMAN SIGN COMPANY, a Texas
corporation ("Debtor") pledges, assigns and grants to Comerica Bank-Texas , a
Texas banking association ("Bank"), whose address is P. O. Box 650282, Dallas,
Texas 75265-0282, Attention: Debra Purvin, a continuing security interest and
lien (any pledge, assignment, security interest or other lien arising hereunder
is sometimes referred to herein as a "security interest") in the Collateral (as
defined below) to secure payment when due, whether by stated maturity, demand,
acceleration or otherwise, of all existing and future indebtedness
("Indebtedness") to the Bank of Debtor under the Loan Agreement (as defined
below) and the Loan Documents. Indebtedness includes without limit any and all
obligations or liabilities of the Debtor to the Bank, whether absolute or
contingent, direct or indirect, voluntary or involuntary, liquidated or
unliquidated, joint or several, known or unknown, originally payable to the Bank
or to a third party and subsequently acquired by the Bank including, without
limitation, any late charges, loan fees or charges, and overdraft indebtedness,
any and all obligations or liabilities for which the Borrower and/or Debtor
would otherwise be liable to the Bank were it not for the invalidity or
unenforceability of them by reason of any bankruptcy, insolvency or other law,
or for any other reason; any and all amendments, modifications, renewals and/or
extensions of any of the above; all costs incurred by Bank in establishing,
determining, continuing, or defending the validity or priority of any security
interest, or in pursuing its rights and remedies under this Agreement or any
Loan Document or in connection with any proceeding involving Bank as a result of
any financial accommodation to Debtor under the Loan Agreement (as defined
below) and the Loan Documents; and all other costs of collecting Indebtedness,
including without limit attorneys' fees. Debtor agrees to pay Bank all such
costs incurred by the Bank, immediately upon demand, and until paid all costs
shall bear interest from the date of such demand until paid in full at the
highest per annum rate applicable to any of the Indebtedness, but not in excess
of the maximum rate permitted by law. Any reference in this Agreement to
attorneys' fees shall be deemed a reference to reasonable fees, costs, and
expenses of both in-house and outside counsel and paralegals, whether inside or
outside counsel is used, whether or not a suit or action is instituted, and to
court costs if a suit or action is instituted, and whether attorneys' fees or
court costs are incurred at the trial court level, on appeal, in a bankruptcy,
administrative or probate proceeding or otherwise.

Reference is made to that certain Second Amended and Restated Revolving Credit
and Term Loan Agreement dated as of September 30, 1998 between Debtor and Bank
(as amended from time to time, the "Loan Agreement"). All capitalized terms used
herein and not otherwise defined herein will have the meanings given such terms
in the Loan Agreement.

1. Collateral shall mean all of the property of Debtor described on Exhibit A
attached hereto and incorporated herein for all purposes.

2. Warranties, Covenants and Agreements. Debtor warrants, covenants and agrees
as follows:

2.1           Debtor shall furnish to Bank, in form and at intervals as Bank may
              reasonably request, any information Bank may reasonably request
              and allow Bank to examine, inspect, and copy any of Debtor's books
              and records. Debtor shall, at the reasonable request of Bank, mark
              its records and the Collateral to clearly indicate the security
              interest of Bank under this Agreement.

2.2           At the time any Collateral becomes, or is represented to be,
              subject to a security interest in favor of Bank, Debtor shall be
              deemed to have warranted that (a) Debtor is the lawful owner of
              the Collateral and has the right and authority to subject it to a
              security interest granted to Bank; (b) none of the Collateral is
              subject to any security interest other than that in favor of Bank
              and other Permitted Liens and there are no financing statements on
              file, other than in favor of Bank; and (c) Debtor acquired its
              rights in the Collateral in the ordinary course of its business.

2.3           Debtor will keep the Collateral free at all times from all claims,
              liens, security interests and encumbrances other than those in
              favor of Bank and other Permitted Liens. Debtor will not, without
              the prior written consent of Bank, sell, transfer or lease, or
              permit to be sold, transferred or leased, any or all of the
              Collateral, except for Inventory or equipment in the ordinary
              course of its business and will not return any Inventory to its
              supplier. Bank or its representatives may at all reasonable times
              inspect the Collateral and may enter upon all premises where the
              Collateral is kept or might be located.

2.4           Debtor will do all acts and will execute or cause to be executed
              all writings reasonably requested by Bank to establish, maintain
              and continue a perfected and first security interest of Bank in
              the Collateral. Debtor agrees that Bank has no obligation to
              acquire or perfect any lien on or security interest in any
              asset(s), whether realty or personalty, to secure payment of the
              Indebtedness, and Debtor is not relying upon assets in which the
              Bank may have a lien or security interest for payment of the
              Indebtedness.

2.5           Debtor will pay within the time that they can be paid without
              interest or penalty all taxes, assessments and similar charges
              which at any time are or may become a lien, charge, or encumbrance
              upon any Collateral, except to the extent contested in good faith
              and bonded in a manner satisfactory to Bank. If Debtor fails to
              pay any of these taxes, assessments, or other charges in the time
              provided above, Bank has the option (but not the obligation) to do
              so, and Debtor agrees to repay all amounts so expended by Bank
              immediately upon demand, together with interest at the highest
              lawful default rate which could be charged by Bank on any
              Indebtedness.

2.6           Debtor will keep the Collateral in good condition and will protect
              it from material loss, damage, or deterioration from any cause
              (ordinary wear and tear excepted). Debtor has and will maintain at
              all times an insurance policy as required under the Loan
              Agreement, including without limitation as to the Collateral. If
              Debtor fails to maintain satisfactory insurance, Bank has the
              option (but not the obligation) to do so and Debtor agrees to
              repay all amounts so expended by Bank immediately upon demand,
              together with interest at the highest lawful default rate which
              could be charged by Bank on any Indebtedness.

2.7           Debtor will do all acts and will execute all writings reasonably
              requested by Bank to perform, enforce performance of, and collect
              all Accounts Receivable. Debtor shall neither make nor permit any
              material modification, compromise or substitution for any Account
              Receivable without the prior written consent of Bank. Debtor
              shall, at Bank's reasonable request, arrange for verification of
              Accounts Receivable directly with account debtors or by other
              methods reasonably acceptable to Bank.

2.8           If Bank, acting in its sole discretion, redelivers Collateral to
              Debtor or Debtor's designee for the purpose of (a) the ultimate
              sale or exchange thereof; or (b) presentation, collection,
              renewal, or registration of transfer thereof; or (c) loading,
              unloading, storing, shipping, transshipping, manufacturing,
              processing or otherwise dealing with it preliminary to sale or
              exchange; such redelivery shall be in trust for the benefit of
              Bank and shall not constitute a release of Bank's security
              interest in it or in the proceeds or products of it unless Bank
              specifically so agrees in writing. If Debtor requests any such
              redelivery, Debtor will deliver with such request a duly executed
              financing statement in form and substance satisfactory to Bank.
              Any proceeds of Collateral coming into Debtor's possession as a
              result of any such redelivery shall be held in trust for Bank and
              immediately delivered to Bank for application on the
              Indebtedness. Bank may (in its sole discretion) deliver any or
              all of the Collateral to Debtor, and such delivery by Bank shall
              discharge Bank from all liability or responsibility for such
              Collateral. Bank, at its option, may require delivery of any
              Collateral to Bank at any time with such endorsements or
              assignments of the Collateral as Bank may reasonably request.

2.9           Upon the occurrence of an Event of Default which is not cured
              within the applicable grace or cure period relating thereto under
              the Loan Agreement, Bank may (a) cause any or all of the
              Collateral to be transferred to its name or to the name of its
              nominees; (b) receive or collect by legal proceedings or
              otherwise all dividends, interest, principal payments and other
              sums and all other distributions at any time payable or
              receivable on account of the Collateral, and hold the same as
              Collateral, or apply the same to the Indebtedness, the manner and
              distribution of the application to be in the sole discretion of
              Bank; (c) enter into any extension, subordination,
              reorganization, deposit, merger or consolidation agreement or any
              other agreement relating to or affecting the Collateral, and
              deposit or surrender control of the Collateral, and accept other
              property in exchange for the Collateral and hold or apply the
              property or money so received pursuant to this Agreement.

2.10          Bank may assign and deliver any or all of the  Collatera  only in
              connection with an assignment of the Loans pursuant to the Loan
              Agreement.

2.11          Section 12.13 of the Loan Agreement is incorporated by reference
              herein.

3. Collection of Proceeds.

3.1           Debtor agrees to collect and enforce payment of all Collateral
              until Bank shall direct Debtor to the contrary. Immediately upon
              notice to Debtor by Bank and at all times after that Debtor agrees
              to fully and promptly cooperate and assist Bank in the collection
              and enforcement of all Collateral and to hold in trust for Bank
              all payments received in connection with Collateral and from the
              sale, lease or other disposition of any Collateral, all rights by
              way of suretyship or guaranty and all rights in the nature of a
              lien or security interest which Debtor now or later has regarding
              Collateral. Upon the occurrence and continuance of any Event of
              Default, and immediately upon and after such notice, Debtor agrees
              to (a) endorse to Bank and immediately deliver to Bank all
              payments received on Collateral or from the sale, lease or other
              disposition of any Collateral or arising from any other rights or
              interests of Debtor in the Collateral, in the form received by
              Debtor without commingling with any other funds, and (b)
              immediately deliver to Bank all property in Debtor's possession or
              later coming into Debtor's possession through enforcement of
              Debtor's rights or interests in the Collateral. While such Event
              of Default is continuing, Debtor irrevocably authorizes Bank or
              any Bank employee or agent to endorse the name of Debtor upon any
              checks or other items which are received in payment for any
              Collateral, and to do any and all things necessary in order to
              reduce these items to money. Bank shall have no duty as to the
              collection or protection of Collateral or the proceeds of it, or
              as to the preservation of any related rights, beyond the use of
              reasonable care in the custody and preservation of Collateral in
              the possession of Bank. Debtor agrees to take all steps necessary
              to preserve rights against prior parties with respect to the
              Collateral. Nothing in this Section 3.1 shall be deemed a consent
              by Bank to any sale, lease or other disposition of any Collateral.

4. Defaults, Enforcement and Application of Proceeds.

4.1           Upon the occurrence and continuance of any "Event of Default" (as
              defined in the Loan Agreement), Debtor shall be in default under
              this Agreement. Additionally, the breach of any representation or
              warranty in any material respect herein will constitute and Event
              of Default.

4.2           Upon the occurrence and during the continuance of any Event of
              Default, Bank may at its discretion and without prior notice to
              Debtor declare any or all of the Indebtedness to be immediately
              due and payable, and shall have and may exercise any right or
              remedy available to it under applicable law or in equity
              including, without limitation, any one or more of the following
              rights and remedies, all in accordance with applicable law:

(a)                 Exercise all the rights and remedies upon default, in
                    foreclosure and otherwise, available to secured parties
                    under the provisions of the Uniform Commercial Code and
                    other applicable law;

(b)                 Institute legal proceedings to foreclose upon the lien and
                    security interest granted by this Agreement, to recover
                    judgment for all amounts then due and owing as Indebtedness,
                    and to collect the same out of any Collateral or the
                    proceeds of any sale of it;

(c)                 Institute legal proceedings for the sale, under the judgment
                    or decree of any court of competent jurisdiction, of any or
                    all Collateral; and/or

(d)                 Personally or by agents, attorneys, or appointment of a
                    receiver, enter upon any premises where Collateral may then
                    be located, and take possession of all or any of it and/or
                    render it unusable; and without being responsible for loss
                    or damage to such Collateral, hold, operate, sell, lease, or
                    dispose of all or any Collateral at one or more public or
                    private sales, leasings or other dispositions, at places and
                    times and on terms and conditions as Bank may deem fit,
                    without any previous demand or advertisement, except as
                    required by law; and except as provided in this Agreement,
                    all notice of sale, lease or other disposition, and
                    advertisement, and other notice or demand, any right or
                    equity of redemption, and any obligation of a prospective
                    purchaser or lessee to inquire as to the power and authority
                    of Bank to sell, lease, or otherwise dispose of the
                    Collateral or as to the application by Bank of the proceeds
                    of sale or otherwise, which would otherwise be required by,
                    or available to Debtor under, applicable law are expressly
                    waived by Debtor to the fullest extent permitted.

              At any sale pursuant to this Section 4.2, whether under the power
              of sale, by virtue of judicial proceedings or otherwise, it shall
              not be necessary for Bank or a public officer under order of a
              court to have present physical or constructive possession of
              Collateral to be sold. The recitals contained in any conveyances
              and receipts made and given by Bank or the public officer to any
              purchaser at any sale made pursuant to this Agreement shall, to
              the extent permitted by applicable law, conclusively establish the
              truth and accuracy of the matters stated (including, without
              limit, as to the amounts of the principal of and interest on the
              Indebtedness, the accrual and nonpayment of it and advertisement
              and conduct of the sale); and all prerequisites to the sale shall
              be presumed to have been satisfied and performed. Upon any sale of
              any Collateral, the receipt of the officer making the sale under
              judicial proceedings or of Bank shall be sufficient discharge to
              the purchaser for the purchase money, and the purchaser shall not
              be obligated to see to the application of the money. Any sale of
              any Collateral under this Agreement shall be a perpetual bar
              against Debtor with respect to that Collateral.

4.3           Debtor shall at the request of Bank, notify the account debtors or
              obligors of Bank's security interest in the Collateral and direct
              payment of it to Bank. Bank may, itself, upon the occurrence and
              during the continuance of any Event of Default so notify and
              direct any account debtor or obligor.

4.4           The proceeds of any sale or other disposition of Collateral
              authorized by this Agreement shall be applied by Bank in such
              order as the Bank, in its discretion, deems appropriate
              including, without limitation, the following order: first upon
              all expenses authorized by the Uniform Commercial Code and all
              reasonable attorneys' fees and legal expenses incurred by Bank;
              the balance of the proceeds of the sale or other disposition
              shall be applied in the payment of the Indebtedness, first to
              interest, then to principal, then to remaining Indebtedness and
              the surplus, if any, shall be paid over to Debtor or to such
              other person(s) as may be entitled to it under applicable law.
              Debtor shall remain liable for any deficiency, which it shall pay
              to Bank immediately upon demand.

4.5           Nothing in this Agreement is intended, nor shall it be construed,
              to preclude Bank from pursuing any other remedy provided by law or
              in equity for the collection of the Indebtedness or for the
              recovery of any other sum to which Bank may be entitled for the
              breach of this Agreement by Debtor. Nothing in this Agreement
              shall reduce or release in any way any rights or security
              interests of Bank contained in any existing agreement between
              Borrower, Debtor, or any Guarantor and Bank.

4.6           No waiver of default or consent to any act by Debtor shall be
              effective unless in writing and signed by an authorized officer of
              Bank. No waiver of any default or forbearance on the part of Bank
              in enforcing any of its rights under this Agreement shall operate
              as a waiver of any other default or of the same default on a
              future occasion or of any rights.

4.7           Debtor irrevocably appoints Bank or any agent of Bank (which
              appointment shall only be effective upon the occurrence and during
              the continuance of an Event of Default and is coupled with an
              interest) the true and lawful attorney of Debtor (with full power
              of substitution) in the name, place and stead of, and at the
              expense of, Debtor:

(a)                 to demand, receive, sue for, and give receipts or
                    acquittances for any moneys due or to become due on any
                    Collateral and to endorse any item representing any payment
                    on or proceeds of the Collateral;

(b)                 to execute and file in the name of and on behalf of Debtor
                    all financing statements or other filings deemed necessary
                    or desirable by Bank to evidence, perfect, or continue the
                    security interests granted in this Agreement; and

(c)                 to do and perform any act on behalf of Debtor permitted or
                    required under this Agreement.

4.8           Upon the occurrence and during the continuance of an Event of
              Default, Debtor also agrees, upon request of Bank, to assemble the
              Collateral and make it available to Bank at any place designated
              by Bank which is reasonably convenient to Bank and Debtor.

5.       Miscellaneous.

5.1           Until Bank is advised in writing by Debtor to the contrary, all
              notices, requests and demands required under this Agreement or by
              law shall be given to, or made upon, Debtor at the first address
              indicated in Section 5.15 below.

5.2           Debtor will give Bank not less than 90 days prior written notice
              of all contemplated changes in Debtor's name, chief executive
              office location, principal place of business location, and/or
              location of any Collateral, but the giving of this notice shall
              not cure any Event of Default caused by this change.

5.3            Bank assumes no duty of performance or other responsibility under
               any contracts contained within the Collateral.

5.4            Bank has the right to sell, assign, transfer, negotiate or grant
               participations or any interest in, any or all of the Indebtedness
               and any related obligations, including without limit this
               Agreement, as set forth in the Loan Agreement. In connection with
               the above, but without limiting its ability to make other
               disclosures to the full extent allowable, Bank may disclose all
               documents and information which Bank now or later has relating to
               Debtor, the Indebtedness or this Agreement, however obtained,
               provided that the recipient of such disclosure shall agree to
               keep any confidential information on a confidential basis. Debtor
               further agrees that Bank may provide information relating to this
               Agreement or relating to Debtor or the Indebtedness to the Bank's
               parent, affiliates, subsidiaries, and service providers, provided
               that the recipient of such disclosure shall agree to keep any
               confidential information on a confidential basis.

5.5           In addition to Bank's other rights, any indebtedness owing from
              Bank to Debtor can be set off and applied by Bank on any
              Indebtedness at any time(s) either before or after maturity or
              demand without notice to anyone. Any such action shall not
              constitute acceptance of collateral in discharge of any portion of
              the Indebtedness.

5.6           Debtor waives any right to require the Bank to: (a) proceed
              against any person or property; or (b) pursue any other remedy in
              the Bank's power. Debtor waives notice of acceptance of this
              Agreement and presentment, demand, protest, notice of protest,
              dishonor, notice of dishonor, notice of default, notice of intent
              to accelerate or demand payment or notice of acceleration of any
              Indebtedness, any and all other notices to which the undersigned
              might otherwise be entitled, and diligence in collecting any
              Indebtedness, and agree(s) that the Bank may, once or any number
              of times, modify the terms of any Indebtedness, compromise,
              extend, increase, accelerate, renew or forbear to enforce payment
              of any or all Indebtedness, or permit Borrower to incur additional
              Indebtedness, all without notice to Debtor and without affecting
              in any manner the unconditional obligation of Debtor under this
              Agreement.

5.7           In the event that applicable law shall obligate Bank to give prior
              notice to Debtor of any action to be taken under this Agreement,
              Debtor agrees that a written notice given to Debtor at least five
              days before the date of the act shall be reasonable notice of the
              act and, specifically, reasonable notification of the time and
              place of any public sale or of the time after which any private
              sale, lease, or other disposition is to be made, unless a shorter
              notice period is reasonable under the circumstances. A notice
              shall be deemed to be given under this Agreement when delivered to
              Debtor as set forth in the Loan Agreement.

5.8           Notwithstanding any prior revocation, termination, surrender, or
              discharge of this Agreement in whole or in part, the effectiveness
              of this Agreement shall automatically continue or be reinstated in
              the event that any payment received or credit given by Bank in
              respect of the Indebtedness is returned, disgorged, or rescinded
              under any applicable law, including, without limitation,
              bankruptcy or insolvency laws, in which case this Agreement, shall
              be enforceable against Debtor as if the returned, disgorged, or
              rescinded payment or credit had not been received or given by
              Bank, and whether or not Bank relied upon this payment or credit
              or changed its position as a consequence of it. In the event of
              continuation or reinstatement of this Agreement, Debtor agrees
              upon demand by Bank to execute and deliver to Bank those documents
              which Bank determines are appropriate to further evidence (in the
              public records or otherwise) this continuation or reinstatement,
              although the failure of Debtor to do so shall not affect in any
              way the reinstatement or continuation.

5.9           This Agreement and all the rights and remedies of Bank under this
              Agreement shall inure to the benefit of Bank's successors and
              assigns and to any other holder who derives from Bank title to or
              an interest in the Indebtedness or any portion of it, and shall
              bind Debtor and the heirs, legal representatives, successors, and
              assigns of Debtor. Nothing in this Section 5.10 is deemed a
              consent by Bank to any assignment by Debtor.

5.10          If there is more than one Debtor, all undertakings, warranties and
              covenants made by Debtor and all rights, powers and authorities
              given to or conferred upon Bank are made or given jointly and
              severally.

5.11          Except as otherwise provided in this Agreement, all terms in this
              Agreement have the meanings assigned to them in Article 9 (or,
              absent definition in Article 9, in any other Article) of the
              Uniform Commercial Code. "Uniform Commercial Code" means the Texas
              Business and Commerce Code as amended.

5.12           No single or partial exercise, or delay in the exercise, of any
               right or power under this Agreement, shall preclude other or
               further exercise of the rights and powers under this Agreement.
               The unenforceability of any provision of this Agreement shall not
               affect the enforceability of the remainder of this Agreement.
               This Agreement constitutes the entire agreement of Debtor and
               Bank with respect to the subject matter of this Agreement. No
               amendment or modification of this Agreement shall be effective
               unless the same shall be in writing and signed by Debtor and an
               authorized officer of Bank. THIS AGREEMENT SHALL BE GOVERNED BY
               AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE
               OF TEXAS, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

5.13          To the extent that any of the Indebtedness is payable upon demand,
              nothing contained in this Agreement shall modify the terms and
              conditions of that Indebtedness nor shall anything contained in
              this Agreement prevent Bank from making demand, without notice and
              with or without reason, for immediate payment of any or all of
              that Indebtedness at any time(s), whether or not an Event of
              Default has occurred.

contemplated by that certain Common Stock Purchase Agreement, dated of even date
hereiwth, by and among the Company, CIVC and MIG, substantially in the form
attached hereto as Exhibit A (the "Common Stock Purchase Agreement"), members of
the Company's management will cease to own at least 25% of the outstanding

reported that it failed to maintain its Net Income at or above the required

The Company has reported that it failed to maintain its Cash Flow Leverage Ratio
at or below the required level for the prior Measurement Period ending December
31, 2000. The Events of Default described in the preceding sentences of this
Section 2 are the "Existing Defaults." On the effective date of this Amendment,
the Purchasers hereby waive the Existing Defaults for the event, Measurement
Period or monthly period, as applicable, indicated. This waiver is limited to
the express terms hereof and shall not extend to any other Default, Event of
Default, period or Computation Period. This waiver is not, and shall not be
deemed, a course of performance upon which the Company may rely with respect to
any other Default, Event of Default or request for a waiver and the Company
expressly waives any such claim.

individual related by blood or marriage to any such Person, or any entity in
which any such Person or individual owns a material beneficial interest, except
for transactions upon fair and reasonable terms no less favorable to the Company
or its Subsidiaries than the terms the Company or its Subsidiaries would obtain
in a comparable arm's-length transaction with a Person not an Affiliate and
approved in advance by the board of directors of the Company. By execution of
this Amendment, the Majority Holders consent to the transactions contemplated by
the Common Stock Purchase Agreement.

                  (c) Pursuant to Section 5P of the Purchase Agreement, the
Company agreed that it would not, without the consent of the Majority Holders,

                  (d) The consents given by the Majority Holders pursuant to
Sections 3(a), 3(b) and 3(c) above are limited to the express terms hereof and
shall not extend to any other actions taken by (or omissions of) the Company.
These consents are not, and shall not be deemed, a course of performance upon
which the Company may rely with respect to any other actions to be taken by (or
omissions of) the Company, and the Company expressly waives any such claim.

                  (c) The execution, delivery and performance of this Amendment

of any applicable bankruptcy, insolvency, reorganization, moratorium or similar
laws affecting creditors' rights generally and general principles of equity
(regardless of whether such enforcement is sought in a proceeding in equity or
