                 10.      Protection of Collateral.  Lender, at its option,

Agreement.

                 11.    Inspection.  Grantor shall at all reasonable times
allow Lender by or through any of its officers, agents, attorneys or
accountants, to examine the Collateral, wherever located, and to examine and
make extracts from Grantor's books and records.

                 12.    Further Assurances.  Grantor shall do, make, procure,
execute and deliver all such additional and further acts, things, deeds,
interests and assurances as Lender may reasonably require from time to time to

at all time with respect to all tangible Collateral insuring against risks of
fire (including so-called extended coverage), theft and other risks as Lender
may reasonably require, containing such terms, in such form and amounts and
written by such companies as may be reasonably satisfactory to Lender, all of
such insurance to contain, if requested by Lender, loss payable clauses in
favor of Lender as its interest may appear.  All policies of insurance shall
provide for fifteen (15) days, written minimum cancellation notice to Lender
and at the request of Lender shall be delivered to and held by it.  Lender is
hereby authorized to act as attorney for Grantor in obtaining, adjusting,
settling and canceling such insurance and endorsing any drafts or instruments.
Lender shall be authorized to apply the proceeds from any insurance to the
Obligations secured hereby whether or not such obligations are then due and
payable.  Grantor specifically authorizes Lender to disclose information from
the policies of insurance to prospective insurers regarding the Collateral.  In
lieu of the foregoing Grantor may self-insure to the extent permitted under
the Loan Documents.

F.               EVENTS OF DEFAULT.  The occurrence or continuance of an "Event
of Default" within the meaning of the Loan Agreement shall constitute an "Event
of Default" under this Agreement.

G.               REMEDIES.  Upon the occurrence of an Event of Default, Lender,
at its option, shall be entitled to exercise any one or more of the following
remedies (all of which are cumulative):

                 1.     Declare Obligations Due.  Lender, at its option, may
declare the obligations or any part thereof immediately due and payable,
without demand, notice of intention to accelerate, notice of acceleration,
notice of nonpayment, presentment, protest, notice of dishonor, or any other
notice whatsoever, all of which are hereby waived by Grantor and any maker,
endorser, guarantor, surety or other party liable in any capacity for any of
the obligations.

                 2.     Remedies.  Lender shall have all of the rights and
remedies provided for in this Agreement and in any other agreements executed by
Grantor, the rights and remedies in


                                       5
<PAGE>   6
the Uniform Commercial Code of Texas, and any and all of the rights and
remedies at law and equity, all of which shall be deemed cumulative.  Without
limiting the foregoing, Grantor agrees that Lender shall have the right to (a)
require Grantor to assemble the Collateral and make it available to Lender at a
place designated by Lender that is reasonably convenient to both parties, which
Grantor agrees to do; (b) take possession of the Collateral, with or without
process of law, and, in this connection, enter any premises where the
Collateral is located to remove same, to render it unusable, or to dispose of
same on such premises; (c) sell, lease or otherwise dispose of the Collateral,
by public or private proceedings, for cash or credit, without assumption of
credit risk; and/or (d) whether before of after default, collect and receipt
for, compound, compromise, and settle, and give releases, discharges and
acquaintances with respect to, any and all amounts owned by any person or
entity with respect to the Collateral.  Unless the Collateral is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market, Lender will send Grantor reasonable notice of the time and
place of any public sale or of the time after which any private sale or other
disposition will be made. Any requirement of reasonable notice to Grantor shall
be met if such notice is mailed, postage prepaid, to Grantor at the address of
Grantor designated at the beginning of this Agreement, at least five (5) days
before the day of any public sale or at least five (5) days before the time
after which any private sale or other disposition will be made.

                 3.       Expenses.  Grantor shall be liable for and agrees to
pay the reasonable expenses incurred by Lender in enforcing its rights and
remedies, in retaking, holding, testing, repairing, improving, selling, leasing
or disposing of the Collateral, or like expenses, including, without
limitation, attorneys' fees and legal expenses incurred by Lender.  These
expenses, together with interest thereon from the date incurred until paid by
Grantor at the maximum contract rate allowed under applicable laws, which
Grantor agrees to pay, shall constitute additional Obligations and shall be
secured by and entitled to the benefits of this Agreement.

                 4.       Proceeds; Surplus; Deficiencies.  Proceeds received
by Lender from disposition of the Collateral shall be applied toward Lender's
expenses and other Obligations in such order or manner as Lender may elect.
Grantor shall be entitled to any surplus if one results after lawful
application of the proceeds.  Grantor shall remain liable for any deficiency.

                 5.       Remedies Cumulative.  The rights and remedies of
Lender are cumulative and the exercise of any one or more of the rights or
remedies shall not be deemed an election of rights or remedies or a waiver of
any other right or remedy.  Lender may remedy any default and may waive any
default without waiving the default remedied or without waiving any other prior
or subsequent default. 

H.               OTHER AGREEMENTS.

                 1.       Savings Clause.  Notwithstanding any provision to the
contrary herein, or in any of the documents evidencing the Obligations or
otherwise relating thereto, no such provision shall require the payment or
permit the collection of interest in excess of the maximum permitted by
applicable usury laws.  If any such excessive interest is so provided for, then
in





                                       6
<PAGE>   7
such event (i) the provisions of this paragraph shall govern and control, (ii)
neither the Grantor nor its successors or assigns or any other party liable for
the payment thereof, shall be obligated to pay the amount of such interest to
the extent that is in excess of the maximum amount permitted by law, (iii) any
such excess interest that may have been collected shall be, at the option of
the holder of the instrument evidencing the Obligations, either applied as a
credit against the then unpaid principal amount thereof or refunded to the
maker thereof, and (iv) the effective rate of interest shall be automatically
reduced to the maximum lawful rate under applicable usury laws as now or
hereafter construed by the courts having jurisdiction.

                 2.       Waivers.  Grantor and any maker, endorser, guarantor,
surety or other party liable in any capacity respecting the Obligations hereby
waive demand, notice of intention to accelerate, notice of acceleration, notice
of nonpayment, presentment, protest, notice of dishonor and any other similar
notice whatsoever, subject to Grantor's rights to notice and cure expressly
provided for in the Loan Agreement.

                 3.       Severability.  Any provision hereof found to be
invalid by courts having jurisdiction shall be invalid only with respect to
such provision (and then only to the extent necessary to avoid such invalidity)
 . The offending provision shall be modified to the maximum extent possible to
confer upon Lender the benefits intended thereby.  Such provision as modified
and the remaining provisions hereof shall be construed and enforced to the same
effect as if such offending provision (or portion thereof) had not been
contained herein, to the maximum extent possible.

                 4.       Use of Copies.  Any carbon, photographic or other
reproduction of any financing statement signed by Grantor is sufficient as a
financing statement for all purposes, including without limitation, filing in
any state as may be permitted by the provisions of the Uniform Commercial Code
of such state.

                 5.       Relationship to Other Agreements.  This Security
Agreement and the security interests (and pledges and assignments as
applicable) herein granted are in addition to (and not in substitution,
notation or discharge of) any and all prior or contemporaneous security
agreements, security interests, pledges, assignments, liens, rights, titles or
other interests in favor of Lender or assigned to Lender by others in
connection with the Obligations.  All rights and remedies of Lender in all such
agreements are cumulative, but in the event of actual conflict in terms and
conditions, the terms and conditions of the latest security-, agreement shall
govern and control.  Grantor acknowledges that it has had full opportunity to
consult with an attorney of its own choice regarding the nature, obligations
and consequences of entering into each of the Loan Documents and that it is not
relying upon counsel for the Lender in this regard.  Grantor and the Lender
have also entered into certain management arrangements under which the Lender
is providing certain management, administrative and accounting services for the
Grantor.  The existence of such management arrangements, including the exercise
by Lender of rights and remedies in that regard, may be deemed to constitute or
give rise to certain conflicts of interest.  Grantor hereby irrevocably,
knowingly and willingly waives all such conflicts.

of the change, amendment, modification waiver or discharge is sought.

pledges and assignments as applicable) hereby granted and all of the terms and
provisions in this Agreement shall be deemed a continuing agreement, until such
time as all Obligations have been paid in full and all commitments of Lender to
make Advances under the Loan Agreement have been terminated, whereupon this
Agreement will terminate.
