     applicable Texas law shall be made pursuant to the indicated rate ceiling
     as defined in Tex.Rev.Civ.Stat.Ann. art. 5069-1.04, but the Lender reserves
     the right to implement from time to time any other rate ceiling permitted

          (b)  Unless the Lender in its sole discretion elects to apply payments
     differently, each payment shall be first credited to the discharge of

     principal.

          (C)  The principal and interest due hereunder shall be evidenced by
     the Lender's records which, absent manifest error, shall be conclusive
     evidence of the computation of principal and interest balances owed by the
     Maker to the Lender.

     4.   DEFAULT. Failure to pay the principal and interest of this Note as
          -------
they become due, or failure of the undersigned or any other person to perform
(after the expiration of any applicable cure period) any of the terms or
provisions set forth in, or the occurrence of any event of default under the
terms of that certain Pledge Agreement of even date herewith between Maker and
Payee (the "Pledge Agreement"), shall, at the election of the holder hereof,
without notice, demand or presentment, which are hereby waived, mature the
principal of this Note and all interest then accrued, and the same shall at once
become due and payable and subject to those remedies of the holder hereof.

     5.   PREPAYMENT. Maker may at any time prepay in whole or in part the
          ----------
unpaid principal of this Note without premium or penalty, and the interest shall
immediately cease on any amounts so prepaid.

     6.   WAIVER. Each surety, endorser, guarantor and any other party now or
          ------

notice of intent to accelerate, notice of acceleration and all other notices,
filing of suit and diligence in collecting this Note or enforcing any other
security with respect to same, (b) agree to any substitution, surrender,
subordination, waiver, modification, change, exchange or release of any security

exhaust its remedies hereon against the Maker, any Surety or others liable or to
become liable hereon or to enforce its rights against them or any security with
respect to same or to join any of them in any suit against any others of them,
and (d) consent to any extension or postponement of time of payment of this Note
and to any other indulgence with respect hereto without notice thereof to any of
them. No failure or delay on the part of the Lender in exercising any right,
power or privilege hereunder shall operate as a waiver thereof.

     7.   ATTORNEYS' FEES. If this Note is not paid at maturity, regardless of
          ---------------
how such maturity may be brought about, or is collected or attempted to be
collected through the initiation or prosecution of any suit or through any
probate, bankruptcy or any other judicial proceedings, or is placed in the hands
of an attorney for collection, the Maker shall pay, in addition to all other
amounts owing hereunder, all actual

expenses of collection, all court costs and reasonable attorney's fees incurred
by the holder hereof.

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

     9.   GOVERNING LAW AND VENUE. This Note and the rights and obligations of
          -----------------------
the parties hereunder shall be governed by the laws of the United States of
America and by the laws of the State of Texas, and is performable in Dallas
County, Texas.

     10.  BUSINESS DAY. If any action is required or permitted to be taken
          ------------
hereunder on a Sunday, legal holiday or other day on which banking institutions
in the State of Texas are authorized or required to close (a "Non-Business
Day"), such action shall be taken on the next succeeding day which is not a Non-
Business Day, and, to the extent applicable, interest on the unpaid principal
balance shall continue to accrue at the applicable rate.

     11.  SECURITY. This Note is the Note referred to in the Pledge Agreement,
          --------
and is entitled to the benefits thereof and the security as provided for
therein. Reference is made to the Pledge Agreement for a statement of the rights
and obligations of Maker, a description of the nature and extent of the security
and the rights of the parties in respect to such security, and a statement of
the terms and conditions under which the due date of this Note may be

          -----
relating to this Note may be brought in the courts of the State of Texas, County
of Dallas, or in the United States District Court for the Northern District of
Texas, Dallas Division. Maker irrevocably waives any objections which it may now
or hereafter have (including any based on the ground of forum non conveniens) to
                                                        --------------------
the laying of venue of any suit, action, or proceeding arising out of or
relating to this Note brought in the courts located in the State of Texas,
County of Dallas. Nothing herein impairs the right to bring proceedings in the
courts of any other jurisdiction.

Party may, but shall never be obligated to, perform or attempt to perform such
covenant, duty or agreement on behalf of Pledgor, and any amount expended by
Secured Party in such performance or attempted performance shall become part of

request of Secured Party, or unless otherwise agreed, Pledgor agrees to pay such
amount promptly to Secured Party.

     6.   ADJUSTMENTS AND DISTRIBUTIONS CONCERNING COLLATERAL. Should the
          ---------------------------------------------------
Collateral, or any part thereof, ever be converted in any manner by its issuer
into another type of property or any money or other proceeds ever be paid or
delivered to Pledgor as a result of Pledgor's rights in the Collateral, then in
any such event (except as provided in Section 7 hereof), all such property,
                                      ---------
money and other proceeds shall immediately be and become part of the Collateral,
and Pledgor covenants to pay forthwith and deliver all such property, money or
other proceeds so received to Secured Party; and, if Secured Party deems it
necessary and so requests, to endorse properly or assign any and all such other
proceeds to Secured Party and to deliver to Secured Party any and all such other
proceeds which require perfection by possession under the Uniform Commercial
Code of the State of Texas or other appropriate jurisdiction (the "UCC"). With
respect to any of such property of a kind requiring an additional security
agreement, financing statement or other writing to perfect a security interest
therein in favor of Secured Party, Pledgor will forthwith execute and deliver to
Secured Party whatever Secured Party shall deem necessary or proper for such
purpose.

     7.   CASH DIVIDENDS AND VOTING RIGHTS. Unless an Event of Default has
          --------------------------------
occurred and shall not have been waived by Secured Party, Pledgor is entitled
(a) to exercise all voting rights with respect to the Collateral and (b) to
receive for its own use 

PLEDGE AGREEMENT - Page 3
<PAGE>
 
cash dividends on the Collateral. Upon the occurrence of an Event of Default,
Secured Party may require any such cash dividends to be delivered to Secured
Party as additional Collateral hereunder or applied toward the satisfaction of
the Obligations.

     8.   REGISTRATION OF COLLATERAL IN NAME OF SECURED PARTY. Upon the
          ---------------------------------------------------
occurrence of an Event of Default Secured Party, at its option, may have any or
all of the Collateral registered in its name or that of its nominee, and Pledgor
hereby covenants that, upon Secured Party's request, Pledgor will cause the
issuer of the Collateral to effect such registration. Immediately and without
further notice, upon the occurrence of an Event of Default, whether or not the
Collateral shall have been registered in the name of Secured Party or its
nominee, Secured Party or its nominee shall have, with respect to the
Collateral, the right to exercise all voting rights and all other corporate
rights and all conversion, exchange, subscription or other rights, privileges or
options pertaining thereto as if it were the absolute owner thereof, including,
without limitation, the right to exchange any or all of the Collateral upon the
merger, consolidation, reorganization, recapitalization or other readjustment of
the issuer thereof, or upon the exercise by such issuer of any right, privilege,
or option pertaining to any of the Collateral, and, in connection therewith, to
deliver any of the Collateral to any committee, depositary, transfer agent,
registrar or other designated agency upon such terms and conditions as it may
determine, all without liability except to account for property actually
received by it; but Secured Party shall have no duty to exercise any of the
aforesaid rights, privileges or options and shall not be responsible for any
failure to do so, delay in doing so, or depreciation in the value of the
Collateral by reason of doing so.

     9.   EVENTS OF DEFAULT. The occurrence of any one or more of the following
          -----------------
shall constitute an Event of Default:

          (a)  The failure of Pledgor to make timely payment of any portion of
     the principal or interest of the Note or any portion of the Obligations
     when due subject to any applicable cure periods;

          (b)  The failure of Pledgor to perform fully, faithfully and promptly
     any material agreements, covenants and conditions contained in this Pledge
     Agreement;

          (c)  The making of any statement, representation, covenant or warranty
     by Pledgor in this Pledge Agreement or in any certificate, agreement,
     instrument or statement contemplated hereby or made or delivered pursuant
     hereto, or in connection herewith, or in any other written agreement
     between Pledgor and Secured Party which is untrue or misleading in any
     material respect at the time such statement, representation, warranty or
     covenant is made;

          (d)  The levy against the Collateral, or any substantial part thereof,
     or any execution, attachment, sequestration, restraint warrant or other
     like or similar writ or the attachment to the Collateral of any lien other

     any other applicable federal or state bankruptcy, insolvency or other
     similar law, or appointing a receiver, liquidator, assignee, custodian,

     liquidation of the affairs of Pledgor and the continuance of any such
     decree or order unstayed and in effect for a period of thirty (30)

     law, or the consent by Pledgor to the appointment of or taking possession
     by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or
     similar official) of Pledgor for any substantial part of Pledgor's
     property, or the making by Pledgeor of any assignment for the benefit of
     creditors, or the inability of Pledgor generally to pay his debts as such
     debts become due, or the taking of any action by Pledgor in furtherance of
     any of the foregoing.

     10.  REMEDIES. Upon the occurrence of an Event of Default, in addition to
          --------
any and all other rights and remedies which Secured Party may then have
hereunder, under the UCC or otherwise, Secured Party may at its discretion and
without notice to Pledgor do any one or more of the following, without liability
except to account for property actually received by it, and Pledgor agrees that
it is commercially reasonable for Secured Party to do any of the following:
(a) declare the entire unpaid balance of principal of and all accrued interest
on the Obligations immediately due and payable without notice, including without
limitation, notice of acceleration and notice of intent to accelerate, demand,
or presentment, which are hereby waived; (b) transfer to or register in its name
or the name of its nominee (if the same has not already been done) any of the
Collateral with or without indication of the security interest herein created,
and whether or not so transferred or registered, receive the income, dividends
and other distributions thereon and hold them or apply them to the Obligations
in any order of payment; (c) exercise or cause to be exercised all voting powers
with respect to any of the Collateral so registered or transferred, including
all rights to conversion, exchange, subscription or any other rights, privileges
or options pertaining to such Collateral, as if the absolute owner thereof; (d)

Party may determine; (e) in its name or in the name of Pledgor demand, sue for,
collect or receive any money or property at any time payable or receivable on

any of the Collateral or the Obligations; (i) add or release any guarantor,
indorser, surety or other party to any of the Collateral or the Obligations; (j)
reduce its claim to judgment or foreclose or otherwise enforce the Security
Interest, in whole or in part, by any available judicial procedure; (k) without
demand of performance or other demand, advertisement or notice of any kind
(except the notice specified below of time and place of public or private sale)
to or upon Pledgor or any other person (all of which are, to the extent
permitted by law, hereby expressly waived), forthwith realize upon the
Collateral or any part thereof, and may forthwith sell or otherwise dispose of
or deliver the Collateral or any part thereof or interest therein, in one or
more parcels at public or private sale or sales, at any exchange, broker's board
or at Secured Party's office or elsewhere, at such prices and on such terms
(including, but without limitation, a requirement that any purchaser of all or
any part of the Collateral purchase the shares constituting the Collateral for
investment without any intention to make any distribution thereof) as it may
deem best (it being agreed that the sale of any part of the Collateral shall not
exhaust Secured Party's power of sale, but sales may be made from time to time
until all of the Collateral has been sold or until the Obligations have been
paid in full without any intention to make any distribution thereof), for cash
or on credit, or for future delivery without assumption of any credit risk, with
the right of Secured Party or any purchaser to purchase upon any such sale the
whole or any part of the Collateral free from any right or equity of redemption
in Pledgor, which right or equity is hereby expressly waived and released, and
at any such sale it shall not be necessary to exhibit the Collateral; (l) apply
by appropriate judicial proceedings for appointment of a receiver for the
Collateral, or any part thereof, and Pledgor hereby consents to any such
appointment; (m) at its discretion, retain the Collateral in satisfaction of the
Obligations whenever the circumstances are such that Secured Party is entitled
to do so under the UCC or otherwise; (n) exercise any and all other rights it
may have hereunder or under the UCC or otherwise. Pledgor hereby grants to
Secured Party an irrevocable proxy coupled with an interest to exercise as to
such Collateral, upon the occurrence of an Event of Default, all rights, powers
and remedies of an owner and all of the rights, powers and remedies hereinabove
set forth, the proxy herein granted to exist until all of the Obligations have
been paid and performed in full.

     11.  APPLICATION OF PROCEEDS. The proceeds of any disposition of the
          -----------------------
Collateral or other action by Secured Party shall be applied (a) first, to the
cost and expenses incurred in connection therewith or incidental thereto or to
the care or safekeeping of any of the Collateral or in any way relating to the
rights of Secured Party hereunder, including reasonable attorneys' fees and
legal expenses; (b) then, to the satisfaction of the Obligations in such order
as Secured Party may elect; (c) then, to the payment of any other amounts
required by applicable law (including, without limitation, Section 9.504(a)(3)
of the UCC); and (d) then, to Pledgor to the extent of any surplus proceeds.
Secured Party shall be under no duty to exercise or to withhold the exercise of
any of the rights, powers, privileges and options expressly or implicitly
granted to Secured Party in this Pledge Agreement, and shall not be responsible
for any failure to do so or delay in so doing.

     12.  LAWS AND AGREEMENTS. Pledgor agrees that, because of the Securities
          -------------------
Act of 1933, as amended (the "SECURITIES ACT"), to the extent applicable, or any
other laws or regulations, and for other reasons, including in order to obtain
any required approval of the purchase or purchaser by any governmental
regulatory agency or officers, there may be legal and/or practical restrictions
or limitations affecting Secured Party in any attempts to dispose of certain
portions of the Collateral and for enforcement of its rights. For these reasons,
Secured Party is hereby authorized by Pledgor, but not obligated, in the event
of the occurrence of an Event of Default, to sell all or any part of the
Collateral at private sale, subject to investment letter or in any other manner
which will not require the Collateral, or any part thereof, to be registered in
accordance with any laws or regulations, including but not limited to the
Securities Act of 1933, to the extent applicable, or the rules and regulations
promulgated thereunder, or make it necessary to obtain any required approval of
the purchase or the purchaser by any governmental regulatory agency or officer,
at the best price reasonably obtainable by Secured Party at such private sale or
other disposition in the manner mentioned above. Pledgor understands that
Secured Party may in its discretion approach a restricted number of potential
purchasers and that a sale under such circumstances may yield a lower price for
the Collateral, or any part or parts thereof, than would otherwise be obtainable
if same were either offered to a large number of potential purchasers, or
registered and sold in the open market. Pledgor agrees that such private sales
shall be deemed to have been made in a commercially reasonable manner and that
Secured Party has no obligation to delay sale of any Collateral to permit the
issuer thereof to register it for public sale under any applicable federal or
state securities laws, and that Secured Party shall not be liable or accountable
to Pledgor, nor shall the Obligations be subject to any reduction by reason of
the fact that the proceeds of sale subject to any such limitation or restriction
are less than otherwise might have been obtained.

     13.  NOTIFICATION OF SALE. Reasonable notification of the time and place of
          --------------------
any public sale of the Collateral, or reasonable notification of the time after
which any private sale or other intended disposition of the Collateral is to be
made, shall be sent to Pledgor and to any other person entitled under the UCC to
notice; provided that if any of the Collateral threatens to decline speedily in
value or is of the type customarily sold on a recognized market, Secured Party
may sell or otherwise dispose of the Collateral without notification,
advertisement, or other notice of any kind. It is agreed that notice sent or
given not less than five (5) calendar days prior to the taking of the action to
which the notice relates is reasonable notification and notice for the purposes
of this paragraph.

     14.  SATISFACTION OF OBLIGATIONS. Upon the satisfaction in full of all
          ---------------------------
Obligations and the satisfaction of all additional costs and expenses of Secured
Party as provided herein, this Pledge Agreement shall terminate, and Secured
Party shall deliver to Pledgor, at Pledgor's expense, such of the Collateral as
shall not have been sold or otherwise applied pursuant to this Pledge Agreement.

     15.  NOTICES. Any notice required or permitted by this Pledge Agreement
          -------
shall be deemed to have been given or made when deposited in the United States
Mail, postage prepaid, certified mail, return receipt requested, addressed to
the parties at the 

PLEDGE AGREEMENT - Page 7
<PAGE>
 
addresses set forth opposite their respective signatures below, or, if hand
delivered, upon actual receipt.

     16.  DUTIES OF SECURED PARTY. Secured Party's duty with respect to any
          -----------------------
Collateral now or hereafter in the possession of Secured Party is solely to use
reasonable care in the custody and preservation of the Collateral. Secured Party
shall be deemed to have exercised reasonable care in the custody and
preservation in the Collateral if the Collateral is accorded treatment
substantially equal to that which Secured Party accords its own property, it
being understood that Secured Party shall not have any responsibility for
ascertaining or taking action with respect to fixing or preserving rights
against prior parties to the Collateral, calls, conversions, exchanges,
maturities, tenders or other matters relative to any Collateral or for informing
Pledgor of such matters whether or not Secured Party has or is deemed to have
any knowledge of such matters. Secured Party shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties
or to protect, perfect, preserve or maintain any security interest given to
secure the Collateral. Secured Party shall never be liable for its failure to
use due diligence in the collection of the Obligations, or any part thereof, or
for its failure to give notice to Pledgor of default in the payment of the
Obligations, or any part thereof, or in the payment of or upon any security,
whether pledged hereunder or otherwise. Secured Party shall not be liable for a
decline in the market value of the Collateral.

     17.  INDEMNIFICATION. Pledgor hereby agrees to indemnify and to hold
          ---------------
Secured Party harmless from and against any loss, claim, demand or expense
(including attorneys' fees) by reason, or in any manner related to, the
Collateral, including any such claim as may arise by reason of any alleged
breach of warranty concerning the Collateral, by reason of the failure of
Pledgor to comply with any state or federal statute, rule, regulation, order or
decree, or by reason of Secured Party's efforts to enforce payment of the
Obligations, including expenses incurred in satisfying any applicable securities
and banking laws.

     18.  EXPENSES. Pledgor will upon demand pay to Secured Party the amount of
          --------
any and all reasonable expenses, including the reasonable fees and expenses of
its counsel and of any experts and agents, which Secured Party may incur in
connection with the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, the exercise or enforcement of
any of the rights of Secured Party hereunder, or the failure by Pledgor to
perform or observe any of the provisions hereof.

     19.  SECURITY INTEREST ABSOLUTE. All rights of Secured Party and the pledge
          --------------------------
and Security Interest hereunder, and all obligations of Pledgor hereunder, shall
be absolute and unconditional in all respects and shall not be released,
diminished, impaired, or affected for any reason, including without limitation
the occurrence of any one or more of the following events: (a) the taking or
accepting of any other security or assurance for any or all of the Obligations;
(b) any change in the time, manner or place of payment of, or in any other term
of, all or any of the Obligations; (c) any exchange, release, subordination,
surrender, loss or non-perfection of any other collateral at any time existing
in connection with any or all of the Obligations, or any release or amendment or
waiver 


PLEDGE AGREEMENT - Page 8
<PAGE>
 
of or consent to departure from any guaranty, or other security, for all
or any of the Obligations; (d) any neglect, delay, omission, failure, or refusal
of Secured Party to take or prosecute any action in connection with this Pledge
Agreement; (e) the insolvency, bankruptcy, or lack of corporate power of
Pledgor; or (f) any other circumstance which might otherwise constitute a
defense available to a discharge of Pledgor in respect of the Obligations of
Pledgor in respect of this Pledge Agreement.


     20.  WAIVERS. Except as otherwise required by the terms hereof or by
          -------
applicable law, Pledgor hereby waives all notices, including but not limited to
demand, presentment for payment, notice of nonpayment, protest, notice of
protest, notice of intent to accelerate, notice of acceleration and all other
notices, and without further notice hereby consents to any and all renewals,
extensions, amendments, modifications, indulgences, releases, subordinations,
waivers or changes in the terms of any of the Obligations.

     21.  REMEDIES CUMULATIVE. The rights and remedies provided herein are
          -------------------
cumulative and are in addition to and not exclusive of any rights or remedies
provided by law, including, but without limitation, the rights and remedies of a
secured party under the UCC.

     22.  AMENDMENT. This Pledge Agreement may be amended only by written
          ---------
instrument signed by both parties. 

     23.  COURSE OF DEALING. No course of dealing between Pledgor and Secured
          -----------------
Party, nor any failure to exercise, nor any delay in exercising, any right,
power or privilege of, Secured Party hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.  

     24.  INVALIDITY OF ANY PROVISION. The invalidity of any one or more
          ---------------------------
phrases, sentences, clauses, paragraphs or sections hereof shall not affect the
remaining portions of this Pledge Agreement, all of which are being inserted
conditionally on their being held legally valid. In the event that any one or
more of the phrases, sentences, clauses, paragraphs or sections contained herein
should be invalid, or should operate to render this Pledge Agreement invalid,
then this Pledge Agreement shall be construed as if such invalid phrase or
phrases, sentence or sentences, clause or clauses, paragraph or paragraphs, or
section or sections had not been inserted.

          ----------

respective legal representatives, successors and assigns, except that the right
