                          EXECUTIVE EMPLOYMENT CONTRACT

     THIS AGREEMENT made as of July 1, 2000 by and between PMC Capital, Inc., a
Florida Corporation with its principal places of business in Dallas, Collin
County, Texas, hereinafter referred to as the "CORPORATION", and Mary J.
Brownmiller; hereinafter referred to as "EXECUTIVE".

                                WITNESSETH THAT:

     In consideration of the promises herein contained, the parties hereto
mutually agree as follows:

     1. Employment: The Corporation hereby employs the Executive as its Senior
Vice President with such powers and duties as may be specified by the Board of
Directors. The Executive hereby accepts employment upon the terms and conditions
as hereinafter set forth.

     2. Term: Subject to the provisions for termination as hereinafter provided,
the term of this Agreement shall begin immediately and shall terminate on (i)
the Executive's seventieth birthday (70th) or (ii) July 31, 2003 or such later
date as determined by the Board of Directors(the "Term"). The Term of this
Executive Employment Contract may be extended annually by the Board of
Directors.

     3. Compensation: For all services rendered by the Executive under this
contract, the Executive shall be paid at a minimum the annual rate effective as
of July 1, 1998 (the "Minimum Rate"). The Minimum Rate may be increased by the
Board at their discretion. The preceding is payable pursuant to the normal
payroll practices of the Corporation.

     The Board of Directors may consider bonus compensation for the Executive if
the performance of PMC Capital, Inc. and the Executive justifies such bonus
compensation.

     4. Authorized Expenses: The Executive is authorized to incur reasonable
expenses for the promotion of the business of the Corporation. The Corporation
will reimburse the Executive for all such reasonable expenses upon the
presentation by the Executive, from time to time, of an itemized account of such
expenditures.

<PAGE>   2

     The Executive shall be entitled to such additional and other fringe
benefits as the Board of Directors shall from time to time authorize.

     5. Extent of Services: The Executive shall devote a substantial portion of
business time, attention and energies to the business of the Corporation, and
shall not, during the term of this Agreement engage in any other business
activities, whether or not such activities are pursued for gain, profit or other
pecuniary advantage. This provision is not meant to prevent her from A) devoting
reasonable time to civic or philanthropic activities or B) investing her assets
in such form or manner providing that it does not require any substantial
services on the part of the Executive that will interfere with the Executive's
employment pursuant to this Agreement. Executive's employment is considered as
full-time.

     6. Working Facilities: The Executive shall be furnished with such
facilities and services suitable to her position and adequate for the
performance of her duties.

     7. Duties: The Executive is employed in an executive and supervisory
capacity and shall perform such duties consistent herewith as the Board of
Directors of the Corporation shall from time to time specify. Subject to the
provisions of Section 17 hereof the precise services of the Executive may be
extended or curtailed, from time to time, at the discretion of the Board of
Directors of the Corporation.

     8. Confidential and Proprietary Information. The Corporation is engaged in
the business of providing commercial loans, including but not limited to, U.S.
Small Business Administration 7(a) and SBIC loans, to qualified borrowers (the
"Corporate Business").

         (a) Executive acknowledges that in order to conduct the Corporate
Business, the Corporation owns and uses certain written and unwritten
confidential and proprietary information, materials, data and know-how about the
Corporate Business that is not generally known in the Corporation's industry and
which may not rise to the level of a trade secret under applicable law. All of
this information has value to and provides competitive advantages to the
Corporation and is owned

<PAGE>   3

by the Corporation and/or is used in the operation of the Corporate Business.
This information includes, but is not limited to customer relationships,
customer lists and prospective customer lists; information provided to the
Corporation by its customers or clients; marketing plans and strategies; methods
of operations and cost data; internal policies and procedures; contracts;
personnel information; and financial information (including fee and pricing
structures, assets, status of client accounts or credit). The preceding
information and any other information which may be designated as confidential by
the Corporation is collectively, referred to as the "Confidential Information".
Executive further acknowledges that during the course of her employment, and as
a result of her employment, she has or will become privy to the Confidential
Information of the Corporation.

         (b) Executive agrees that both during and after termination of her
employment with the Corporation for any reason, Executive will hold all
Confidential Information in trust and confidence for the Corporation's benefit
and will not use or disclose any Confidential Information that Executive
acquires or obtains during the time Executive works as an Executive for the
Corporation, except as specifically authorized by the President of the
Corporation, in writing. This limitation applies whether the Confidential
Information was developed by Executive or whether or not Executive has been
authorized to have access to the Confidential Information. Executive further
agrees to comply with all of the Corporation's requirements, policies and
procedures for protecting Confidential Information and further agrees to comply
with the Corporation's policies concerning confidentiality obligations the
Corporation has agreed to undertake as a result of agreements with its
customers, clients, or others.

         (c) The foregoing prescriptions against use, disclosure and copying do
not apply to information or data which: (i) was known by Executive and reduced
to writing prior to the date the Executive began work with the Corporation; (ii)
is available in published print or otherwise known to the public, unless
published or made known as a result of some act or omission on the Executive's
part; or (iii) is lawfully obtained by Executive in writing from a third party
who did not acquire such

<PAGE>   4

information or data directly or indirectly from Executive, the Corporation or
other party prohibited from transmitting the information to Executive.

     9. Non-Solicitation: Customers and Clients. In recognition of the close
personal contact Executive has or will have with the Corporation's Confidential
Information, records and business relationships, and the position of trust in
which the Corporation holds Executive, Executive agrees as follows: while
Executive is employed with the Corporation, and for a period of three (3) years
following the date on which Executive employment with the Corporation is
terminated for any reason, Executive shall not, either on his behalf or as an
officer, director, executive, agent, representative, independent contractor or
in any relationship to any person, partnership, corporation or other entity,
solicit or accept directly or by assisting others, business from any of the
Corporation's existing customers and clients with whom Executive has had
material contact (as hereinafter defined) during the Executive's employment, for
the purpose of providing goods or services to said customers which are directly
competitive with goods or services then being provided by the Corporation to
said customers. For the purposes of this Agreement, "material contact" exists
between Executive and each of the Corporation's existing customers: (i) with
whom Executive actually dealt with; or (ii) whose dealings with the Corporation
were handled, coordinated or supervised by Executive; or (iii) about whom
Executive obtained Confidential Information in the ordinary course of business
through Executive's association with the Corporation. Executive acknowledges
that this provision is intended to protect the Corporate Business and the
Corporation's customer contacts, not to prevent Executive from pursuing a
livelihood in the general area of his previous training, and it should be
interpreted accordingly.

     10. Non-Solicitation: Employees, Consultants and Independent Contractors.
In recognition of the close personal contact Executive has or will have with the
Corporation's, Confidential Information, records and business relationships, and
the position of trust in which the Corporation holds Executive, Executive agrees
as follows: while Executive is employed with the Corporation, and

<PAGE>   5

for a period of three (3) years following the date on which Executive's
employment with the Corporation is terminated for any reason, Executive shall
not recruit, induce or influence or seek to recruit or employ directly or by
assisting others, any person who is employed by the Corporation or who is
associated with the Corporation as a consultant or independent contractor at the
time of the termination of the Executive's employment and with whom Executive
had material contract (as hereinafter defined) during Executive's employment
with the Corporation, to leave or terminate his or her employment or
relationship with the Corporation. For the purposes of this Agreement, "material
contact" exists between Executive and other employees, consultants and/or
independent contractors of the Corporation: (i) with whom Executive actually
dealt; or (ii) whose employment or dealings with the Corporation or services for
the Corporation were handled, coordinated or supervised by the Executive. This
section is intended to protect the Corporate Business and its significant
investment in the training, development and loyalty of its employees,
consultants and independent contractors, not to prevent Executive from pursuing
a livelihood in the general area of his previous training, and it should be
interpreted accordingly.

     11. Non-Compete. As part of the essence of the consideration hereof, during
Executive's employment hereunder for a period three (3) years from and after the
termination of her employment under this Agreement or any renewal term hereof
(the "Termination"), whether such termination is voluntary or involuntary,
Executive agrees and covenants that she will not collectively or individually
engage in or become affiliated with, directly or indirectly, either for herself
or as a member of a joint venture, partnership or corporation, or as a major
stockholder, consultant, officer or director in a corporation, or as an
Executive or agent on behalf of any person, firm, joint venture, partnership or
corporation, any business which offers or performs commercial lending or loan
brokerage services or related services which are the same or substantially
similar to the Corporate Business or other services offered by the Corporation
at any time during the three (3) years immediately prior to such termination,
within any of the metropolitan areas in which Executive has worked in any
capacity on behalf of the

<PAGE>   6

Corporation at any time during the three (3) years immediately preceding the
termination.

     12. Vacations: The Executive shall be entitled each year to a vacation in
accordance with the vacation policy of the Corporation.

     13. Disability: If the Executive is unable to perform his services by
reason of illness or total incapacity, based on standards similar to those
utilized by the U.S. Social Security Administration he shall receive his full
salary for one (1) year of said total incapacity through coordination of
benefits with any existing disability insurance program provided by the
Corporation (a reduction in salary by that amount paid by any company provided
insurance). Should said Executive be totally incapacitated beyond a one-year
period, so that he is not able to devote full time to his employment with said
Corporation, then this Agreement shall terminate.

     14. Death During Employment: If the Executive dies during the term of
employment and has not attained the age of seventy years old, the Corporation
and/or any third party insurance provided by the Corporation, through a
coordination of benefits, shall pay the estate of the Executive a death benefit
equal to two times the Executive's annual salary. In the event the Executive
receives death benefits payable under any group life insurance policy issued to
the Corporation, the Corporation's liability under this clause will be reduced
by the amount of the death benefit paid under such policy. The Corporation shall
pay any remaining death benefits to the estate of the Executive over the course
of twelve (12) months in the same manner and under the same terms as the
Executive would have been paid if the had still been working for the
Corporation. No later than one (1) month from the date of death, the estate of
the Executive will also be paid any accumulated vacation pay. Such payments
pursuant to this paragraph shall constitute the full compensation of said
Executive and he and his estate shall have no further claim for compensation by
reason of his employment by the Corporation.

<PAGE>   7

     15. Assignment: The acts and obligations of the Corporation under this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Corporation.

     16. Invalidity: If any paragraph or part of this Agreement is invalid, it
shall not affect the remainder of this Agreement but the remainder shall be
binding and effective against all parties.

     17. Additional Compensation: If during the Term, this Agreement is
terminated by the Corporation (other than pursuant to the provisions of Section
18 hereof) or by the Executive due to "Constructive Discharge" then the
Executive shall receive termination pay in an amount equal to 2.99 times the
Minimum Rate. For purposes of this Agreement, "Constructive Discharge" shall
mean:

          o Any reduction in salary below the Minimum Rate;

          o A material change diminishing the Executive's job function,
            authority, duties or responsibilities, or a similar change
            deteriorating Executive's working conditions that would not be in
            accordance with the spirit of this Agreement;

          o A required relocation of Executive of more than 35 miles from
            Executive's current job location; or requires Executive to travel
            away from Executive's office in the course of discharging
            Executive's responsibilities in excess of that typically required of
            executives in similar positions.

          o Any breach of any of the terms of this Agreement by the Corporation
            which is not cured within 14 days following written notice thereof
            by Executive to the Corporation.

The amount payable by the Corporation pursuant to this Section 17 shall be made
in one lump sum cash payment payable to the Executive no later than 30 days
following termination of this Agreement.

     18. Termination: The Corporation cannot terminate this agreement except
for: 1) the intentional, unapproved misuse of corporate funds, 2a) professional
incompetence (i.e. the

<PAGE>   8

intentional refusal to perform or the inability to perform the duties associated
with Executive's position with the Corporation in a competent manner, which is
not cured within 15 days following written notice to Executive) or 2b) willful
neglect of duties or responsibilities in either case not otherwise related to or
triggered by the occurrence of any event or events described in or prescribed by
Section 17 hereof.

     19. Remedies for Breach by Executive. The Corporation provides the
livelihood and financial stability for a number of employees and investors that
will continue after the hiring and employment of Executive. Both parties agree
that compliance with the covenants and provisions contained herein are necessary
to protect the business and goodwill of the Corporation and that a breach will
result in irreparable and continuing damage to the Corporation. Both parties
agree that it is impossible to measure or compensate in money alone the damages
that would accrue in the event of Executive's failure to perform his obligations
hereunder. Therefore, if Executive breaches any covenant or provision hereof,
the Corporation shall have, at its option (without limiting any other right or
remedy which may be available either simultaneously or alternatively): (i) the
right and remedy to have such provisions enforced by specific enforcement,
injunctive relief or other equitable remedy by any court of competent
jurisdiction, and (ii) the right and remedy to require Executive to account for
and pay over to the Corporation all compensation, profits, monies, accruals,
increments or other benefits (collectively the "benefits"), derived or received
by Executive ( or her successors and assigns) as a result of any transactions
constituting a breach of any of the provisions hereof, and (iii) any other
remedy provided by law.

     20. Indemnification: The Corporation hereby agrees to indemnify and hold
the Executive harmless from any loss for any corporate undertaking, as
contemplated in Paragraph 7 herein, whereby a claim, allegation or cause of
action shall be made against the Executive in the performance of her contractual
duties except for willful illegal misconduct. Said indemnification shall include
but not be limited to reasonable cost incurred in defending the Executive in her
faithful performance of contractual duties.

     21. Entire Agreement: This contract may not be changed except in writing
and embodies the whole Agreement between the parties hereto and there are no
inducements, promises, terms, conditions or obligations made or entered into by
the Corporation or the Executive other than contained herein. This Executive
Employment Contract supercedes and replaces that certain Executive Employment
Contract dated July 1, 1999 between the Corporation and the Executive.

IN WITNESS WHEREOF, the parties here hereunto signed and sealed this Agreement
the date first above written.

severally and not jointly agrees to lend to Borrower such Lender's Commitment
Percentage of one or more Borrowings under the Revolving Facility not to exceed
such Lender's Committed Sum, which, subject to the Credit Documents, Borrower
may borrow, repay and reborrow under this agreement, provided that (a) each such
Borrowing must occur on a Business Day and no later than the Business Day
immediately preceding the Termination Date, (b) each such Borrowing shall be in
an amount not less than $500,000 or a greater integral multiple of $100,000, and
(c) on any date of determination, the Commitment Usage shall never exceed the
Commitment.

         2.2 Borrowing Procedure. The following procedures apply to all
Borrowings:

                  (a) Borrowing Request. Borrower may request a Borrowing only
         by making or delivering a Borrowing Request to Administrative Agent,
         which is irrevocable and binding on Borrower, stating the Type, amount
         and, if applicable, Interest Period for each Borrowing and which must
         be received by Administrative Agent no later than (i) 10:00 a.m. on the
         second Business Day before the date on which funds are requested (the
         "Borrowing Date") for any LIBOR Rate Borrowing or (ii) 10:00 a.m. on
         the Borrowing Date for any Base Rate Borrowing. Administrative Agent
         shall promptly notify each Lender of any Borrowing Request.

                                       14
<PAGE>   21

                  (b) Funding. Each Lender shall remit its Commitment Percentage
         of each requested Borrowing to Administrative Agent's principal office
         in Dallas, Texas, in funds that are available for immediate use by
         Administrative Agent by 2:00 p.m. on the applicable Borrowing Date.
         Subject to receipt of those funds, Administrative Agent shall (unless
         to its actual knowledge any of the applicable conditions precedent have
         not been satisfied by Borrower or waived by the requisite Lenders under
         Section 14.10) make those funds available to Borrower by (at Borrower's
         option) (i) wiring the funds to or for the account of Borrower at the
         direction of Borrower or (ii) depositing the funds in Borrower's
         account with Administrative Agent.

                  (c) Funding Assumed. Absent contrary written notice from a
         Lender, Administrative Agent may assume that each Lender has made its
         Commitment Percentage of the requested Borrowing available to
         Administrative Agent on the applicable Borrowing Date, and
         Administrative Agent may, in reliance upon such assumption (but shall
         not be required to), make available to Borrower a corresponding amount.
         If a Lender fails to make its Commitment Percentage of any requested
         Borrowing available to Administrative Agent on the applicable Borrowing
         Date, Administrative Agent may recover the applicable amount on demand,
         (i) from that Lender together with interest, commencing on the
         Borrowing Date and ending on (but excluding) the date Administrative
         Agent recovers the amount from that Lender, at an annual interest rate
         equal to the Federal Funds Rate, or (ii) if that Lender fails to pay
         its amount upon demand, then from Borrower. No Lender is responsible
         for the failure of any other Lender to make its Commitment Percentage
         of any Borrowing; however, failure of any Lender to make its Commitment
         Percentage of any Borrowing does not excuse any other Lender from
         making its Commitment Percentage of any Borrowing.

         2.3 Borrowing Requests. Each Borrowing Request constitutes a
representation and warranty by Borrower that as of the Borrowing Date, all of
the conditions precedent for that Borrowing in Section 5 have been satisfied.

         2.4 Reduction or Termination of Commitment by Borrower. Without premium
or penalty, and upon giving not less than three Business Days prior written and
irrevocable notice to Administrative Agent, Borrower may terminate in whole or
in part the unused portion of the Commitment; provided that: (a) each partial
termination shall be in an amount of not less than $5,000,000 or a greater
integral multiple of $2,500,000; (b) the amount of the Commitment may not be
reduced below the Commitment Usage at such time; and (c) each reduction shall be
allocated among the Lenders in accordance with their respective Commitment
Percentages. Promptly after receipt of such notice of termination or reduction,
Administrative Agent shall notify each Lender of the proposed cancellation or
reduction. Such termination or partial reduction of the Commitment shall be
effective on the Business Day specified in Borrower's notice (which date must be
at least three Business Days after Borrower's delivery of such notice). In the
event that the Commitment is reduced to zero at a time when there is no
outstanding Principal Debt, this agreement shall be terminated (except for any
indemnification or expense reimbursement provisions in this Agreement which
survive the termination of this Agreement) and all commitment fees and other
fees then earned and unpaid hereunder and all other amounts constituting part of
the Obligation then due and owing shall be immediately due and payable, without
notice or demand by Administrative Agent or any Lender.

         2.5 Extensions of the Stated Termination Date. On or before November 15
th of each calendar year which occurs prior to the Stated Termination Date (as
the same may have been extended hereunder) but not sooner than 30 days preceding
such date, Borrower may submit a request to Administrative Agent and Lenders to
extend the Stated Termination Date for an additional year by delivering to
Administrative Agent

                                       15
<PAGE>   22

a written request to extend the Stated Termination Date. Any Lender may decline
to grant such extension for any reason in their sole and absolute discretion. If
the Lenders decline to extend the Stated Termination Date, Borrower shall be
required to fully repay all of the Obligation on the Stated Termination Date
then in effect. Neither Administrative Agent nor any Lender is under any
obligation to extend or refinance all or any portion of the Obligation at any
time. If the Lenders agree to extend the Stated Termination Date, Administrative
Agent and Lenders may, in their sole and absolute discretion, specify the
conditions applicable to such extension, which may include, without limitation,
the delivery to Administrative Agent and Lenders of such documents, instruments
and assurances as Administrative Agent and Lenders deem necessary or appropriate
to evidence such extension.

SECTION 3. TERMS OF PAYMENT.

         3.1 Notes and Payments.

                  (a) Notes. The Principal Debt shall be evidenced by the Notes,
         one payable to each Lender in the maximum stated principal amount of

                  (b) Payment. Borrower must make each payment and prepayment on
         the Obligation to Administrative Agent's principal office in Dallas,
         Texas in immediately available funds by 1:00 p.m. on the day due;
         otherwise, but subject to Section 3.8, those funds continue to accrue
         interest as if they were received on the next Business Day.
         Administrative Agent shall promptly pay to each Lender the part of any
         payment or prepayment to which that Lender is entitled under this
         agreement on the same day Administrative Agent is deemed to receive the
         funds from Borrower.

                  (c) Payment Assumed. Unless Administrative Agent has received
         notice from Borrower prior to the date on which any payment is due
         under this agreement, that Borrower will not make that payment in full,
         Administrative Agent may assume that Borrower has made the full payment
         due and Administrative Agent may, in reliance upon that assumption,
         cause to be distributed to each Lender on that date the amount then due
         to each Lender. If and to the extent Borrower does not make the full
         payment due to Administrative Agent, each Lender shall repay
         Administrative Agent on demand the amount distributed to that Lender by
         Administrative Agent, together with interest for each day from the date
         that Lender received payment from Administrative Agent until the date
         that Lender repays Administrative Agent (unless such repayment is made
         on the same day as such distribution), at an interest rate equal to the
         Federal Funds Rate.

         3.2 Interest and Principal Payments.

                  (a) Interest. Interest on each LIBOR Rate Borrowing shall be
         due and payable as it accrues on the last day of its respective
         Interest Period and on the Termination Date; provided that if any
         Interest Period is a period greater than three months, then accrued
         interest shall also be due and payable on the date three months after
         the commencement of such Interest Period. Interest on each Base Rate
         Borrowing shall be due and payable as it accrues on the last day of
         each month (commencing on the first of those dates that follows the
         Closing Date), and on the Termination Date.

                  (b) Principal. The Principal Debt under the Revolving Facility
         is due and payable on the Termination Date. After giving Administrative
         Agent advance written notice of the intent to prepay, Borrower may
         voluntarily prepay all or any part of the Principal Debt from time to
         time and at any time, in whole or in part, without premium or penalty;
         provided that: (i) such notice must be received by Administrative Agent
         by 10:00 a.m. on (A) the third Business Day preceding the date of

                                       16
<PAGE>   23

         prepayment of a LIBOR Rate Borrowing, and (B) one Business Day
         preceding the date of prepayment of a Base Rate Borrowing; (ii) each
         such partial prepayment must be in a minimum amount of at least
         $500,000 or a greater integral multiple of $100,000 thereof (if a LIBOR
         Rate Borrowing or a Base Rate Borrowing); (iii) all accrued interest on
         the Obligation must also be paid in full, to the date of such
         prepayment; and (iv) Borrower shall pay any related Consequential Loss
         within ten (10) days after demand therefor. Each notice of prepayment
         shall specify the prepayment date, the facility or the subfacility
         hereunder being prepaid, the Type of Borrowing(s) and amount(s) of such
         Borrowing(s) to be prepaid and shall constitute a binding obligation of
         Borrower to make a prepayment on the date stated therein.

                  (c) Mandatory Prepayments. Borrower shall make mandatory
         prepayments on the Obligation to Administrative Agent in the following
         amounts (without duplication):

                           (i) On any date of determination, if the Commitment
                  Usage exceeds the Commitment then in effect, then Borrower
                  shall make a mandatory prepayment of the Principal Debt under
                  the Revolving Facility in at least the amount of any such
                  excess, together with (A) all accrued and unpaid interest on
                  the principal amount so prepaid and (B) any Consequential Loss
                  arising as a result thereof;

                           (ii) 100% of the Net Proceeds from any sale (subject
                  in all respects to Section 8.10) of assets by Borrower or any
                  other Company, other than any sale of assets which are
                  obsolete or are no longer in use and which are not significant
                  to the continuation of Borrower's or such Company's business;

                           (iii) 100% of the Net Proceeds received by the
                  Companies in connection with any Structured Financing or Asset
                  Securitization; and

                           (iv) 100% of the Net Proceeds received by the
                  Companies in connection with any Equity Issuance.

         Mandatory prepayments made pursuant to clauses (ii) - (iv) above
         (together with any related Consequential Loss) are payable on the same
         Business Day on which the proceeds of such sale, securitization or
         issuance are received by the applicable Company, and must be made
         together with (A) all accrued and unpaid interest on the principal
         amount so prepaid and (B) any Consequential Loss arising as a result
         thereof. If the amount of any mandatory prepayment required hereunder
         is greater than the then-outstanding Obligation, any such excess may be
         retained by Borrower. In addition, notwithstanding the foregoing, the
         requirement that a Company make prepayments in accordance with clauses
         (ii) - (iv) above shall not apply to the extent that any such
         prepayment would violate any rules or regulations of the Small Business
         Administration applicable to such Company (provided that prepayments
         shall be made up to the maximum amount permitted to be paid under those
         rules and regulations).

                  (d) Mandatory Annual "Clean-up" Period. Borrower shall repay
         the entire outstanding principal balance of the Revolving Facility,
         together with all accrued but unpaid interest thereon, for a period of
         at least 30 consecutive days during each calendar year.

         3.3 Interest Options. Except that the LIBOR Rate may not be selected
when an Event of Default or Potential Default exists, and except as otherwise
provided in this agreement, Borrowings bear interest at an annual rate equal to
the lesser of (a) the Base Rate plus the Applicable Margin or the LIBOR Rate
plus the

                                       17
<PAGE>   24

Applicable Margin (in each case as designated or deemed designated by Borrower),
as the case may be and (b) the Maximum Rate. Each change in the Base Rate, LIBOR
Rate or Maximum Rate is effective, without notice to Borrower or any other
Person, upon the effective date of change. If Borrower does not designate the
Type for a requested Borrowing, then the requested Borrowing shall be deemed to
be a LIBOR Rate Borrowing with an Interest Period of one month (unless the LIBOR
Rate is unavailable because of the conditions described in Sections 3.15 or
3.17, in which case the requested Borrowing will be deemed a Base Rate
Borrowing).

         3.4 Quotation of Rates. Borrower may call Administrative Agent before
delivering a Borrowing Request to receive an indication of the interest rates
then in effect, but the indicated rates do not bind Administrative Agent or
Lenders or affect the interest rate that is actually in effect when Borrower
makes a Borrowing Request or on the Borrowing Date.

         3.5 Default Rate. All past-due Principal Debt and, unless prohibited by
applicable Government Requirements, past-due interest accruing on the Principal
Debt shall, at Administrative Agent's option, bear interest on the amount
thereof from time to time outstanding from the date due (stated or by
acceleration) at the Default Rate until paid, regardless of whether payment is
made before or after entry of a judgment.

         3.6 Interest Recapture. If the designated interest rate applicable to
any Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent reductions in the designated
rate shall not reduce the interest rate thereon below the Maximum Rate until the
total amount of accrued interest equals the amount of interest that would have
accrued if that designated rate had always been in effect. If at maturity
(stated or by acceleration), or at final payment of the Notes, the total
interest paid or accrued is less than the interest that would have accrued if
the designated rates had always been in effect, then, at that time and to the
extent not prohibited by applicable Governmental Requirements, Borrower shall
pay an amount equal to the difference between (a) the lesser of the amount of
interest that would have accrued if the designated rates had always been in
effect and the amount of interest that would have accrued if the Maximum Rate
had always been in effect, and (b) the amount of interest actually paid or
accrued on the Notes.

         3.7 Interest Calculations. Interest on all Borrowings will be
calculated on the basis of actual number of days (including the first day but
excluding the last day) elapsed but computed as if each calendar year consisted
of 365 or 366 days, as the case may be. All interest rate determinations and
calculations by Administrative Agent are conclusive and binding absent manifest
error.

         3.8 Maximum Rate. It is the intent of Administrative Agent, Lenders and
Borrower in the execution and performance of the Credit Documents to remain in
strict compliance with applicable Governmental Requirements from time to time in
effect, including applicable laws limiting the amount or rate of interest.
Administrative Agent, Lenders and Borrower stipulate and agree that none of the
terms and provisions contained in the Credit Documents shall ever be construed
to create a contract to pay for the use, forbearance or detention of money with
interest at a rate or in an amount in excess of the Maximum Rate or Maximum
Amount. For purposes of the Credit Documents, "interest" shall include the
aggregate of all charges which constitute interest under applicable Governmental
Requirements that are contracted for, charged, reserved, received or paid under
the Credit Documents. Borrower shall never be required to pay unearned interest
and shall never be required to pay interest at a rate or in an amount in excess
of the Maximum Rate or Maximum Amount, and the provisions of this section shall
control over all other provisions of the Credit Documents, and of any other
instrument pertaining to or securing the Obligation, which may be in actual or
apparent conflict herewith. If the Obligation is prepaid, or if the maturity of
the Obligation is

                                       18
<PAGE>   25

accelerated for any reason, or if under any contingency the effective rate or
amount of interest which would otherwise be payable under the Credit Documents
would exceed the Maximum Rate or Maximum Amount, or in the event any Lender or
any holder of the Notes shall charge, contract for, take, reserve or receive
monies that are deemed to constitute interest which would, in the absence of
this provision, increase the effective rate or amount of interest payable under
the Credit Documents to a rate or amount in excess of that permitted to be
charged, contracted for, taken, reserved or received under applicable
Governmental Requirements then in effect, then the principal amount of the
Obligation or the amount of interest which would otherwise be payable under the
Notes or both shall be reduced to the amount allowed under applicable
Governmental Requirements as now or hereinafter construed by the courts having
jurisdiction, and all such moneys so charged, contracted for, taken, reserved or
received that are deemed to constitute interest in excess of the Maximum Rate
shall immediately be returned to or credited to the account of Borrower upon
such determination. Administrative Agent, Lenders and Borrower further stipulate
and agree that, without limitation of the foregoing, all calculations of the
rate or amount of interest contracted for, charged, taken, reserved or received
under the Credit Documents which are made for the purpose of determining whether
such rate or amount exceeds the Maximum Rate or Maximum Amount, shall be made to
the extent not prohibited by applicable Governmental Requirements, by
amortizing, prorating, allocating and spreading during the period of the full
stated term of the Notes, all interest at any time contracted for, charged,
taken, reserved or received from Borrower or otherwise by Lenders or any other
holder of the Notes. If the Governmental Requirements of the State of Texas are
applicable for purposes of determining the "Maximum Rate," such term shall mean
"the "weekly rate ceiling" from time to time in effect under Chapter 1D.,
Subtitle 1, Title 79, Revised Civil Statutes of Texas (Article 5069-1D.001 et
seq.), as amended, or, if permitted by applicable Governmental Requirements and
effective upon the giving of the notices required by such applicable
Governmental Requirements (or effective upon any other date otherwise specified
by applicable Governmental Requirements), the "monthly ceiling," the "quarterly
ceiling," or "annualized ceiling" from time to time in effect under such
applicable Governmental Requirements, whichever that the Lenders shall elect to
substitute for the "weekly rate ceiling."

         3.9 Interest Periods. When Borrower requests any LIBOR Rate Borrowing,
Borrower may elect the applicable interest period (each an "Interest Period"),
which may be, at Borrower's option, one, three or six months, subject to the
following conditions: (a) the initial Interest Period for a LIBOR Rate Borrowing
commences on the applicable Borrowing Date or conversion date, and each
subsequent Interest Period applicable to any Borrowing commences on the day when
the next preceding applicable Interest Period expires; (b) if any Interest
Period for a LIBOR Rate Borrowing begins on a day for which no numerically
corresponding Business Day in the calendar month at the end of the Interest
Period exists, then the Interest Period ends on the last Business Day of that
calendar month; (c) if Borrower is required to pay any portion of a LIBOR Rate
Borrowing before the end of its Interest Period in order to comply with the
payment provisions of the Credit Documents, Borrower shall also pay any related
Consequential Loss; (d) no Interest Period for any portion of Principal Debt may
extend beyond the scheduled repayment date for that portion of Principal Debt;
and (e) no more than four Interest Periods may be in effect at one time.

         3.10 Conversions. Subject to the dollar limits of Section 2.1 and
provided that Borrower may not convert to or select a new Interest Period for a
LIBOR Rate Borrowing at any time when an Event of Default exists, Borrower may
(a) convert a LIBOR Rate Borrowing on the last day of the applicable Interest
Period to a Base Rate Borrowing, (b) convert a Base Rate Borrowing at any time
to a LIBOR Rate Borrowing and (c) elect a new Interest Period for a LIBOR Rate
Borrowing. That election may be made by telephonic request to Administrative
Agent no later than 10:00 a.m. on the second Business Day before the conversion
date or the last day of the Interest Period, as the case may be (for conversion
to a LIBOR Rate Borrowing or election of a new Interest Period), and no later
than 10:00 a.m. on the last day of the Interest Period (for

                                       19
<PAGE>   26

conversion to a Base Rate Borrowing). Borrower shall provide a Conversion Notice
to Administrative Agent no later than two days after the date of the conversion
or election. Absent Borrower's telephonic request for conversion or election of
a new Interest Period or if an Event of Default exists, then, a LIBOR Rate
Borrowing shall be deemed converted to a Base Rate Borrowing effective when the
applicable Interest Period expires.

         3.11 Order of Application.

                  (a) No Event of Default. Payments and prepayments of the
         Obligation shall be applied in the order and manner specified in this
         agreement; provided, however, if no order is otherwise specified in
         this agreement and no Event of Default or Potential Default has
         occurred and is continuing, payments and prepayments of the Obligation
         shall be applied first to fees, second to accrued interest then due and
         payable on the Principal Debt, and then to the remaining Obligation in
         the order and manner as Borrower may direct.

                  (b) Event of Default or No Direction. If an Event of Default
         or Potential Default has occurred and is continuing (or if Borrower
         fails to give direction as permitted under Section 3.11(a)), any
         payment or prepayment (including proceeds from the exercise of any
         Rights) shall be applied in the following order: (i) to all fees and
         expenses for which Administrative Agent or Lenders have not been paid
         or reimbursed in accordance with the Credit Documents (and if such
         payment or prepayment is less than all unpaid or unreimbursed fees and
         expenses, then the payment or prepayment shall be paid against unpaid
         and unreimbursed fees and expenses in the order of incurrence or due
         date); (ii) to accrued interest on the Principal Debt; (iii) to the
         remaining Principal Debt in such order as Required Lenders may elect
         (provided that Required Lenders will apply such proceeds in an order
         that will minimize any Consequential Loss); and (iv) to the remaining
         Obligation in the order and manner Required Lenders deem appropriate.

                  (c) Pro Rata. Each payment or prepayment shall be distributed
         to each Lender in accordance with its Pro Rata Part of that payment or
         prepayment.

         3.12 Sharing of Payments, Etc. If any Lender obtains any payment or
prepayment with respect to the Obligation (whether voluntary, involuntary, or
otherwise, including, without limitation, as a result of exercising its Rights
under Section 3.13) that exceeds the part of that payment or prepayment that it
is then entitled to receive under the Credit Documents, then that Lender shall
purchase from the other Lenders participations that will cause the purchasing
Lender to share the excess payment or prepayment ratably with each other Lender.
If all or any portion of any excess payment or prepayment is subsequently
recovered from the purchasing Lender, then the purchase shall be rescinded and
the purchase price restored to the extent of the recovery. Borrower agrees that
any Lender purchasing a participation from another Lender under this section
may, to the fullest extent permitted by applicable Governmental Requirements,
exercise all of its Rights of payment (including the Right of offset) with
respect to that participation as fully as if that Lender were the direct
creditor of Borrower in the amount of that participation.

         3.13 Offset. If an Event of Default exists, to the extent not
prohibited by applicable Governmental Requirements, each Lender may exercise
(for the benefit of all Lenders in accordance with Section 3.12) the Rights of
offset and banker's lien against each and every account and other property, or
any interest therein, that any Company may now or hereafter have with, or which
is now or hereafter in the possession of, that Lender to the extent of the full
amount of the Obligation owed (directly or participated) to it, provided,

                                       20
<PAGE>   27

however, no such right of offset or banker's lien may be exercised against any
account of any Special Purpose Entity.

         3.14 Booking Borrowings. To the extent permitted by applicable
Governmental Requirements, any Lender may make, carry, or transfer its
Borrowings at, to, or for the account of any of its branch offices or the office
or branch of any of its Affiliates. However, no Affiliate or branch is entitled
to receive any greater payment under Section 3.16 than the transferor Lender
would have been entitled to receive with respect to those Borrowings, and a
transfer may not be made if, as a direct result of it, Section 3.15 or 3.17
would apply to any of the Obligation. If any of the conditions of Sections 3.16
or 3.17 ever apply to a Lender, that Lender shall, to the extent possible, carry
or transfer its Borrowings at, to, or for the account of any of its branch
offices or the office or branch of any of its Affiliates so long as the transfer
is consistent with the other provisions of this section, does not create any
burden or adverse circumstance for that Lender that would not otherwise exist,
and eliminates or ameliorates the conditions of Sections 3.16 or 3.17, as
applicable.

         3.15 Basis Unavailable or Inadequate for LIBOR Rate. If on or before
any date when a LIBOR Rate is to be determined for a Borrowing, Administrative
Agent or any Lender determines (and Required Lenders agree with that
determination) that the basis for determining the applicable rate is not
available or that the resulting rate does not accurately reflect the cost to
Lenders of making or converting Borrowings at that rate for the applicable
Interest Period, then Administrative Agent shall promptly notify Borrower and
Lenders of that determination (which is conclusive and binding on Borrower
absent manifest error), and the applicable Borrowing shall bear interest at the
sum of the Base Rate plus the Applicable Margin. Until Administrative Agent
notifies Borrower that those circumstances giving rise to such notice no longer
exist, Lenders' commitments under this agreement to make, or to convert to,
LIBOR Rate Borrowings, as the case may be, shall be suspended.

         3.16 Additional Costs. Each Lender severally and not jointly agrees to
notify Administrative Agent, the other Lenders, and Borrower within 180 days
after it has actual knowledge that any circumstances exist that would give rise
to any payment obligation by Borrower under clauses (a) through (c) below.
Although no Lender shall have any liability to Administrative Agent, any other
Lender, or any Company for its failure to give that notice, Borrower is not
obligated to pay any amounts under those clauses that arise, accrue or are
imposed more than 180 days before that notice to the extent that notice is
applicable to those amounts. To demand payment under this section, any such
Lender must generally be making similar demand for similar additional costs
under credit agreements to which it is party that contain similar provisions to
this section.

                  (a) Reserves. With respect to any LIBOR Rate Borrowing (i) if
         any change in any present Governmental Requirement, any change in the
         interpretation or application of any present Governmental Requirement,
         or any future Governmental Requirement imposes, modifies or deems
         applicable (or if compliance by any Lender with any requirement of any
         Governmental Authority results in) any requirement that any reserves
         (including, without limitation, any marginal, emergency, supplemental,
         or special reserves) be maintained (other than any reserve included in
         the Reserve Requirement) and if (ii) those reserves reduce any sums
         receivable by that Lender under this agreement or increase the costs
         incurred by Lender in advancing or maintaining any portion of any LIBOR
         Rate Borrowing, then (iii) that Lender (through Administrative Agent)
         shall deliver to Borrower a certificate setting forth in reasonable
         detail the calculation of the amount necessary to compensate it for its
         reduction or increase (which certificate is conclusive and binding
         absent manifest error), and (iv) Borrower shall pay that amount to that
         Lender within five Business Days after demand. The provisions of and
         undertakings and indemnifications in this clause (a) survive the
         satisfaction and payment of the Obligation and termination of this
         agreement.

                                       21
<PAGE>   28

                  (b) Capital Adequacy. With respect to any Borrowing, if any
         change in any present Governmental Requirement, any change in the
         interpretation or application of any present Governmental Requirement,
         or any future Governmental Requirement regarding capital adequacy, or
         if compliance by Administrative Agent or any Lender with any request,
         directive or requirement imposed in the future by any Governmental
         Authority regarding capital adequacy, or if any change in its written
         policies or in the risk category of this transaction, in any of the
         foregoing events or circumstances, reduces the rate of return on its
         capital as a consequence of its obligations under this agreement to a
         level below that which it otherwise could have achieved (taking into
         consideration its policies with respect to capital adequacy) by an
         amount deemed by it to be material (and it may, in determining the
         amount, utilize reasonable assumptions and allocations of costs and
         expenses and use any reasonable averaging or attribution method), then
         (unless the effect is already reflected in the rate of interest then
         applicable under this agreement) Administrative Agent or that Lender
         (through Administrative Agent) shall notify Borrower and deliver to
         Borrower a certificate setting forth in reasonable detail the
         calculation of the amount necessary to compensate it (which certificate
         is conclusive and binding absent manifest error), and Borrower shall
         pay that amount to Administrative Agent or that Lender within five
         Business Days after demand. The provisions of and undertakings and
         indemnification in this clause (b) shall survive the satisfaction and
         payment of the Obligation and termination of this agreement.

                  (c) Taxes. Any Taxes payable by Administrative Agent or any
         Lender or ruled by a Governmental Authority to be payable by
         Administrative Agent or any Lender in respect of this agreement or any
         other Credit Document shall, if permitted by applicable Governmental
         Requirements, be paid by Borrower, together with interest and
         penalties, if any, except for Taxes payable on or measured by the
         overall net income of Administrative Agent or that Lender (or any other
         Person with whom Administrative Agent or that Lender files a
         consolidated, combined, unitary, or similar Tax return) and except for
         interest and penalties incurred as a result of the gross negligence or
         willful misconduct of Administrative Agent or that Lender.
         Administrative Agent or that Lender (through Administrative Agent)
         shall notify Borrower and deliver to Borrower a certificate setting
         forth in reasonable detail the calculation of the amount of Taxes
         payable, which certificate is conclusive and binding (absent manifest
         error), and Borrower shall pay that amount to Administrative Agent for
         its account or the account of that Lender, as the case may be, within
         ten Business Days after demand. If Administrative Agent or that Lender
         subsequently receives a refund of the Taxes paid to it by Borrower,
         then the recipient shall promptly pay the refund to Borrower.

         3.17 Change in Governmental Requirements. If any Governmental
Requirement makes it unlawful for any Lender to make or maintain LIBOR Rate
Borrowings, then that Lender shall promptly notify Borrower and Administrative
Agent, and (a) as to undisbursed funds, that requested Borrowing shall be made
as a Base Rate Borrowing and (b) as to any outstanding Borrowing (i) if
maintaining the Borrowing until the last day of the applicable Interest Period
is unlawful, the Borrowing shall be converted to a Base Rate Borrowing as of the
date of notice, in which event Borrower will be required to pay any related
Consequential Loss or (ii) if not prohibited by applicable Governmental
Requirements, the Borrowing shall be converted to a Base Rate Borrowing as of
the last day of the applicable Interest Period or (iii) if any conversion will

                  (b) The proceeds of the Revolving Facility will be used by

         reducing or retiring any indebtedness which was originally incurred to
         purchase or carry a margin stock or for any other purpose which might
         constitute this transaction a "purpose credit" within the meaning of
         such Regulation U. No Company is engaged in the business of extending
         credit for the purpose of purchasing or carrying margin stocks. No
         Company, nor any Person acting on behalf of any Company, has taken or
         will take any action that might cause the Notes or any of the other

         Regulation U or any other regulations of the Board of Governors of the
         Federal Reserve System or to violate Section 7 of the Securities
         Exchange Act of 1934, as amended, or any rule or regulation thereunder,

         effect.

                  (c) No portion of any advance or loan made hereunder shall be
         used directly or indirectly to purchase ineligible securities, as
         defined by applicable regulations of the Federal Reserve Board,

of its obligations under those Credit Documents (i) are within its corporate
power, (ii) have been duly authorized by all necessary corporate action, (iii)

         Officer of Borrower setting forth details as to that Reportable Event

         notice of that Reportable Event which may be required to be filed with
         the PBGC, or any notice delivered by the PBGC evidencing its intent to
         institute those proceedings or any notice to the PBGC that the Employee
         Plan is to be terminated, as the case may be. For all purposes of this
         section, Borrower is deemed to have all knowledge of all facts
         attributable to the plan administrator under ERISA.

                  (h) Other Notices. Promptly after Borrower knows or receives
         any notification thereof (whichever shall first occur), notice of (a)
         the existence and status of any Litigation or Environmental Liability
         that if determined adversely to any Company, could reasonably be
         expected to result in a Material Adverse Event, (b) change in any fact
         or circumstance (other than of an inconsequential nature) represented
         or warranted by any Company in any Credit Document, (c) an Event of
         Default, Potential Default or Material Adverse Event, specifying the
         nature thereof and what action the Companies have taken, are taking and

         or "potential default" from any other creditor of the Companies, with a
         copy thereof immediately delivered to Administrative Agent, together
         with an explanation from Borrower, in detail satisfactory to
         Administrative Agent, regarding the notice and effect of such notice.

                  (i) Other Information. Promptly when reasonably requested by
         Administrative Agent or any Lender, such additional information (not
         otherwise required to be furnished under this agreement) regarding any
         Company's business affairs, assets, liabilities, results of operation
         and financial condition as Administrative Agent or any Lender may

for the purposes represented in this agreement.

         7.3 Books and Records. Each Company shall maintain books, records and

                                       31
<PAGE>   38

         7.4 Inspections. Upon reasonable request and advance notice (but during
the pendency of an Event of Default, no advance notice is required), each
Company shall allow Administrative Agent or any Lender (or their respective
Representatives) to inspect any of that Company's properties, to review reports,
files and other records and to make and take away copies, to conduct tests or
investigations and to discuss any of its affairs, conditions and finances with
its other creditors, directors, officers, employees, outside accountants or
representatives from time to time, during reasonable business hours (but during
the pendency of an Event of Default, at any time). Without limiting the
foregoing, the Companies shall allow Administrative Agent to perform field
examinations to test such systems and controls of the Companies as it deems
appropriate. If such inspections or field examinations are performed when no
Event of Default or Potential Default exists, the Administrative Agent and
Lenders will bear the cost of such field examinations. If such field
examinations are performed when an Event of Default or Potential Default exists,
Borrower shall promptly reimburse Administrative Agent and Lenders for the
reasonable expenses of such inspections and field examinations.

         7.5 Taxes. Each Company shall promptly pay when due any and all Taxes,
except Taxes that are being contested in good faith by lawful proceedings
diligently conducted, against which reserve or other provision required by GAAP
has been made and in respect of which levy and execution of any Lien sufficient
to be enforced has been and continues to be stayed.

         7.6 Payment of Obligation. Each Company shall promptly pay (or renew

Administrative Agent incident to any Credit Document (including, without
limitation, the reasonable fees and expenses of Administrative Agent's counsel
in connection with the negotiation, preparation, delivery and execution of the
Credit Documents and any related amendment, waiver or consent) and (b) all
reasonable costs and expenses incurred by Administrative Agent in connection
with the enforcement of the obligations of any Company under the Credit
Documents or the exercise of any Rights under the Credit Documents (including,
without limitation, reasonable allocated costs of in-house counsel, other
reasonable attorneys' fees and court costs), all of which are part of the
Obligation, bearing interest (if not paid within ten Business Days after demand
accompanied by an invoice describing the costs, fees and expenses in reasonable
detail) on the portion thereof from time to time unpaid at the Default Rate
until paid.

         7.8 Maintenance of Existence, Assets and Business. Each Company shall
(a) maintain its trust, corporate or partnership (as applicable) existence and
good standing in its state of incorporation or formation (as applicable) and (b)
except where the failure to perform any of the following could not reasonably be
expected to result in a Material Adverse Event (i) maintain its authority to
transact business and good standing in all other states, (ii) maintain all
licenses, permits and franchises necessary or desirable for its business and
(iii) keep all of its assets that are useful in and necessary to its business in
good working order and condition (ordinary wear and tear excepted) and make all

with financially sound, responsible and reputable insurance companies or
associations, or as to workers' compensation or similar insurance, with an
insurance fund or by self-insurance authorized by the jurisdictions in which it

                                       32
<PAGE>   39

addition, Borrower shall and shall cause each other Company to, (a) name
Administrative Agent as additional insured on all general and comprehensive
liability insurance, (b) deliver copies of the policies and endorsements for the
insurance required by this Section 7.9 to Administrative Agent promptly after
issuance and renewal of each and (c) cause each policy of insurance to provide
that it will not be cancelled or modified (as to term, coverage, scope, property
or risks covered, change or addition of loss payee or additional insured or
otherwise) without 30 days prior written notice to Administrative Agent.

         7.10 Compliance with Governmental Requirements. Each Company shall (a)
operate and manage its businesses and otherwise conduct its affairs in
compliance with all Governmental Requirements (including without limitation, all
Environmental Laws and Environmental Permits) except to the extent noncompliance
reasonably could be expected not to constitute a Material Adverse Event, (b)
promptly deliver to Administrative Agent a copy of any notice received from any
Governmental Authority alleging that any Company is not in compliance with any
Governmental Requirements (including any Environmental Laws or Environmental
Permits) if the allegation reasonably could constitute a Material Adverse Event
and (c) promptly deliver to Administrative Agent a copy of any notice received
from any Governmental Authority alleging that any Company has any potential
Environmental Liability if the allegation reasonably could constitute a Material
Adverse Event.

         7.11 Indemnification.

         ADMINISTRATIVE AGENT, ARRANGER AND EACH LENDER OR ANY OF THOSE
         AFFILIATES OR REPRESENTATIVES; AND (iii) "INDEMNIFIED LIABILITIES"
         MEANS ALL PRESENT AND FUTURE, KNOWN AND UNKNOWN, FIXED AND CONTINGENT,
         ADMINISTRATIVE, INVESTIGATIVE, JUDICIAL AND OTHER CLAIMS, DEMANDS,
         ACTIONS, CAUSES OF ACTION, INVESTIGATIONS, SUITS, PROCEEDINGS, AMOUNTS

         AND DISBURSEMENTS (INCLUDING ALL REASONABLE ATTORNEYS' FEES AND
         EXPENSES WHETHER OR NOT SUIT OR OTHER PROCEEDING EXISTS OR ANY
         INDEMNITEE IS PARTY TO ANY SUIT OR OTHER PROCEEDING) IN ANY WAY RELATED
         TO ANY OF THE FOREGOING, THAT MAY AT ANY TIME BE IMPOSED ON, INCURRED
         BY, OR ASSERTED AGAINST, ANY INDEMNITEE AND IN ANY WAY RELATING TO OR
         ARISING OUT OF ANY (1) CREDIT DOCUMENT OR TRANSACTION CONTEMPLATED BY
         ANY CREDIT DOCUMENT, (2) ENVIRONMENTAL LIABILITY IN ANY WAY RELATED TO
         ANY COMPANY, OR ACT, OMISSION, STATUS, OWNERSHIP, OR OTHER
         RELATIONSHIP, CONDITION, OR CIRCUMSTANCE CONTEMPLATED BY, CREATED
         UNDER, OR ARISING PURSUANT TO OR IN CONNECTION WITH ANY CREDIT
         DOCUMENT, OR (3) INDEMNITEE'S SOLE OR CONCURRENT ORDINARY NEGLIGENCE.

                  (b) EACH INDEMNITOR AGREES, JOINTLY AND SEVERALLY, TO
         INDEMNIFY PROTECT AND DEFEND EACH INDEMNITEE FROM AND AGAINST, HOLD
         EACH INDEMNITEE HARMLESS FROM AND AGAINST, AND ON DEMAND PAY OR

                                       33
<PAGE>   40

                  (c) THE FOREGOING PROVISIONS (i) ARE NOT LIMITED IN AMOUNT
         EVEN IF THAT AMOUNT EXCEEDS THE OBLIGATION, (ii) INCLUDE, WITHOUT
         LIMITATION, REASONABLE FEES AND EXPENSES OF ATTORNEYS AND OTHER COSTS
         AND EXPENSES OF LITIGATION OR PREPARING FOR LITIGATION AND DAMAGES OR
         INJURY TO PERSONS, PROPERTY, OR NATURAL RESOURCES ARISING UNDER ANY
         STATUTORY OR COMMON LAW GOVERNMENTAL REQUIREMENT, PUNITIVE DAMAGES,
         FINES, AND OTHER PENALTIES, AND (iii) ARE NOT AFFECTED BY THE SOURCE OR
         ORIGIN OF ANY HAZARDOUS SUBSTANCE, AND (iv) ARE NOT AFFECTED BY ANY
         INDEMNITEE'S INVESTIGATION, ACTUAL OR CONSTRUCTIVE KNOWLEDGE, COURSE OF
         DEALING, OR WAIVER.

                  (d) However, no Indemnitee is entitled to be indemnified under
         the Credit Documents for its own fraud, gross negligence, or wilful
         misconduct.

                  (e) Although failure to do so does not reduce or impair any
         Indemnitor's obligations under this section, each Indemnitee shall
         promptly notify Borrower of any event about which the Indemnitee has
         received written notice and that is reasonably likely to result in any
         Indemnified Liability. Each Indemnitor may, at its own cost and
         expense, participate in the defense in any proceeding involving any
         Indemnified Liability. If no Event of Default or Potential Default
         exists, Indemnitors may assume the defense in that proceeding on behalf
         of the applicable Indemnitees, including the employment of counsel if
         first approved (which approval may not be unreasonably withheld) by the
         applicable Indemnitees. If Indemnitors assume any defense, they shall
         keep the applicable Indemnitees fully advised of the status of, and
         shall consult with, and receive the concurrence of, those Indemnitees
         before taking any material position in respect of, that proceeding. If
         Indemnitors consent, if an Event of Default, Potential Default or
         Material Adverse Event exists or if any Indemnitee reasonably
         determines that an actual conflict of interests exists between
         Indemnitors and that Indemnitee with respect to the subject matter of
         the proceeding or that Indemnitors are not diligently pursuing the
         defense, then (i) that Indemnitee may, at Indemnitors' joint and
         several expense, employ counsel to represent that Indemnitee that is
         separate from counsel for Indemnitors or any other Person in that
         proceeding and (ii) Indemnitors are no longer entitled to assume the
         defense on behalf of that Indemnitee. No Indemnitor may agree to the
         settlement of any Indemnified Liability, or any matters or issues
         material to or necessary for the resolution of any such liability,
         without the prior written consent of the applicable Indemnitees unless,
         as agreed to in writing by an Indemnitee, that settlement fully
         relieves those Indemnitees of any liability whatsoever for that
         Indemnified Liability. If an Indemnitee agrees to the settlement of any
         Indemnified Liability without the prior written consent of Indemnitors
         (which consent may not be unreasonably withheld), then Indemnitors are
         no longer obligated for that Indemnified Liability in respect of that
         Indemnitee.

         7.12 Negative Pledge. Borrower hereby covenants and agrees (and agrees
to cause each other Company) not to directly or indirectly create, incur, grant,
suffer, or permit to be created or incurred any Lien on any of the respective
assets of such Companies, other than Permitted Liens. Furthermore, in the event
that, notwithstanding the foregoing, any such Liens (other than Permitted Liens)
are granted, incurred, or created, then, in addition to the other Rights granted
to Administrative Agent and Lenders hereunder or under applicable Governmental
Requirements, (a) the Companies hereby grant to Administrative Agent and Lenders
an equal and ratable Lien in and to the property so encumbered, (b) any Person
receiving the benefit of any such additional Liens shall be deemed to receive
any such grant or conveyance of Liens for the ratable and pari passu benefit of
Lenders and Administrative Agent and shall be deemed the bailee and agent for
such Lenders for the sole purpose of holding any such collateral and Liens and
perfecting Liens in favor of Administrative Agent and Lenders with respect
thereto, and (c) upon the request of Administrative Agent, each Company shall
execute, and shall request the other Person to execute, all such documents and
take all

                                       34

actions requested by Required Lenders to more fully evidence and create such
ratable, pari passu Liens in favor of Lenders and Administrative Agent.

         7.13 Subsidiary Guaranties. It is expressly understood by the parties
to this agreement that, as of the Closing Date, certain provisions in the loan
documentation evidencing the Existing Debt prohibit the Subsidiaries from
guaranteeing the Obligation. If at any time after the Closing Date such Existing
Debt is repaid and not simultaneously reborrowed or such prohibitions are
otherwise eliminated, Borrower shall cause each of its Subsidiaries to promptly
execute unlimited guaranties of the Obligation in form reasonably satisfactory
to Administrative Agent and Lenders.

SECTION 8. NEGATIVE COVENANTS. For so long as any Lender is committed to lend
under this agreement and until the Obligation has been fully paid and performed,

proceeds of any Borrowing (a) for any purpose other than as represented in this

                           (ii) Debt existing on the Closing Date, as more

                  is unsecured, (B) such Debt is non-recourse to the other
                  Companies, (C) at the time such Debt is incurred, no Event of
                  Default, Potential Default or Material Adverse Event then

                  the Companies are in good standing with the SBA and are in
                  material compliance with all SBA rules and requirements
                  pertaining to the issuance of such Debt, and (E) the loan
                  documentation in effect with respect to such Debt provides for
                  interest-only payments for at least the five year period
                  following the Closing Date;

                           (iv) Debt arising under or in connection with any
                  Structured Financing that is entered into as a result of an
                  Asset Securitization; and

                           (v) indebtedness and other obligations arising under
                  Rate Management Transactions contemplated by this agreement.

         Section 8.2(a)(ii) above in connection with the sale of

         Purpose Entity incurred in connection with an Asset Securitization, so

         transferred to Borrower.

         8.3 Liens. No Company may (a) create, incur or suffer or permit to be
created or incurred or to exist any Lien upon any of its properties except a
Permitted Lien or (b) enter into or permit to exist any arrangement or agreement
that directly or indirectly prohibits any Company from creating or incurring any
Lien on any of its assets or properties except (i) the Credit Documents, (ii)

         8.4 Employee Plans. No Company may permit any of the events or
circumstances described in Section 6.11 to exist or occur except where the
failure to perform the foregoing could not reasonably be expected to result in a
Material Adverse Event.

         8.5 Transactions with Affiliates. No Company may enter into any
transaction with any of its Affiliates except (a) Asset Securitizations, but
only so long as (i) no Event of Default or Potential Default has occurred and is
continuing at the time of such Asset Securitization, and (ii) all mandatory
prepayments on the Obligation required by Section 3.2(c) are made in connection
therewith, and (b) transactions (other than Investments) in the ordinary course
of business and upon fair and reasonable terms not materially less favorable
than it could obtain or could become entitled to in an arm's-length transaction
with a Person that was not its Affiliate. For the avoidance of doubt, if the
other conditions stated therein are satisfied, clause (a) above permits Borrower
to enter into joint Asset Securitizations with its Affiliate, PMC Commercial
Trust, whereby both Borrower and PMC Commercial Trust contribute assets to a
Special Purpose Entity owned jointly by Borrower and PMC Commercial Trust.

         8.6 Compliance with Governmental Requirements and Documents. No Company
shall (a) violate the provisions of any Governmental Requirements (including,
without limitation, OSHA and Environmental Laws) applicable to it or of any
material agreement to which it is a party or by which any of its property is
subject or bound if that violation alone, or when aggregated with all other
violations, reasonably could be expected to result in a Material Adverse Event,
(b) violate any provision of its Organizational Documents or (c) repeal, replace
or amend any provision of its Organizational Documents if that action reasonably
could be expected to result in a Material Adverse Event.

following (the "Permitted Investments"):

                  (a) (i) Readily marketable, direct, full faith and credit
         obligations of the United States of America or obligations guaranteed
         by the full faith and credit of the United States of America and (ii)
         readily marketable obligations of an agency or instrumentality of, or
         corporation owned, controlled or sponsored by, the United States of
         America that are generally considered in the securities industry to be

         United States of America given on the date of such investment a credit

         the making of the investment;

                  (d) Certificates of deposit issued by, bank deposits in,
         eurodollar deposits through, bankers' acceptances of, and repurchase
         agreements covering Government Securities executed by, any branch or
         office located in the United States of America of a bank incorporated
         under the

                                       37

         investment;

         involving a Special Purpose Entity; and

                  (h) Customary capital contributions or similar investments
         relating to the formation of any Subsidiary of that Company.

         8.8 Distributions; Other Payments. No Company shall enter into or
permit to exist any arrangement or agreement which directly or indirectly
prohibits any such Company from declaring, making or paying, directly or
indirectly, any Distribution to Borrower, except for the requirements imposed by
the Small Business Administration that the Companies maintain minimum levels of
capital. No Company shall, directly or indirectly, declare, make or pay any
Distributions except for:

interests in any other Company) other than pursuant to a Permitted Asset Sale.

         8.10 Mergers, Consolidations and Dissolutions. No Company may merge or
consolidate with any other Person, or acquire, in one or a series of related
transactions, all or substantially all of the equity or assets of any Person. In
addition, no Company may dissolve or convert to any other form of entity.

<PAGE>   46

Company fails or refuses to punctually and properly perform, observe and comply
with any covenant or agreement in any Credit Document (other than covenants to
pay the Obligation and covenants set forth in Sections 8 and 9) applicable to
it, and that failure or refusal continues for 15 days after that Company has, or
with the exercise of reasonable diligence should have had, notice of that
failure or refusal; provided, however, that with respect to the failure or
refusal to perform any such covenant or agreement, Borrower shall not be
entitled to an opportunity to cure any such failure or refusal if such failure

currency or currencies, or any warrant of attachment, sequestration, or similar

required to be prepaid by any Company before its stated maturity.

void, or the validity or enforceability of any Credit Document or any Lender
Lien is contested by any Company or any other Person, or any Company or any
other Person asserts the absence of, or denies that it has, any liability or

accordance with that document's express provisions, or any Lender Lien shall

breach or cancellation of, any agreement or other contractual arrangement to

perform any of its payment or other material obligations under any Credit
Document or (ii) the ability of Administrative Agent or Lenders to enforce any

any of Borrower's Commercial Loans; or (vii) any governmental action shall have

SECTION 11. RIGHTS AND REMEDIES.

         11.1 Remedies Upon Event of Default.

                  (a) Debtor Relief. If an Event of Default exists under Section
         10.3, the commitment to extend credit under this agreement
         automatically terminates and the entire unpaid principal balance of the
         Obligation, together with all interest accrued thereon, and all other
         amounts then accrued and unpaid, automatically become and shall be due
         and payable without any action of any kind whatsoever.

                  (b) Other Events of Default. If any Event of Default exists,
         Administrative Agent may (with the consent of, and must, upon the
         request of Required Lenders), do any one or more of the following: (i)
         If the maturity of the Obligation has not already been accelerated
         under Section 11.1(a), declare the entire unpaid principal balance of
         all or any part of the Obligation, together with all interest accrued
         thereon, and all other amounts then accrued and unpaid, immediately due
         and

                                       42
<PAGE>   49

         payable, whereupon it is due and payable; (ii) terminate the
         commitments of Lenders to extend credit under this agreement; (iii)
         reduce any claim to judgment; (iv) require the Companies to open and
         maintain a secured lockbox account for the receipt of the Companies'
         accounts receivables; notes receivable and other receivables; and (v)
         exercise any and all other legal or equitable Rights afforded by the
         Credit Documents, by applicable Governmental Requirements or otherwise
         at law or in equity.

                  (c) Offset. If an Event of Default exists, to the extent not
         prohibited by applicable Governmental Requirements, each Lender may
         exercise the Rights of offset and banker's lien against each and every
         account and other property, or any interest therein, which any Company
         may now or hereafter have with, or which is now or hereafter in the
         possession of, that Lender to the extent of the full amount of the
         Obligation owed to that Lender, provided, however, no such right of
         offset or banker's lien may be exercised against any account of a
         Special Purpose Entity.

         11.2 Company Waivers. To the extent not prohibited by applicable
Governmental Requirements, Borrower and each other Company waives, in respect to
any action taken by Administrative Agent or Lenders at any time and from time to
time pursuant to Section 11.1, presentment, demand for payment, protest,
acceleration, notice of protest and nonpayment, notice of intention to
accelerate, notice of acceleration, and all other notices and acts, and agrees
that its liability with respect to all or any part of the Obligation is not
affected by any renewal or extension in the time of payment of all or any part
of the Obligation, by any indulgence, increase or other modification to, or by
any release or change in any security for the payment of, all or any part of the
Obligation.

         11.3 Performance by Administrative Agent. If any Company's covenant,
duty or agreement is not performed in accordance with the terms of the Credit
Documents, Administrative Agent may at its option (but subject to the approval
of Required Lenders), perform or attempt to perform that covenant, duty or
agreement on behalf of that Company, and any amount expended by or on behalf of
Administrative Agent in its performance or attempted performance is payable by
the Companies, jointly and severally, to Administrative Agent on demand, becomes
part of the Obligation, and bears interest on the portion thereof from time to
time unpaid at the Default Rate from the date of Administrative Agent's
expenditure until paid. However, Administrative Agent does not assume and shall
never have, except by its express written consent, any liability or
responsibility for the performance of any Company's covenants, duties or
agreements. Notwithstanding the forgoing, unless an Event of Default then
exists, Administrative Agent shall not take any such action without requesting
that Borrower take such action on its own behalf.

         11.4 Not in Control. Nothing in any Credit Document gives or may be
deemed to give to Administrative Agent or any Lender the Right to exercise
control over any Company's Real Property, other assets, affairs or management or
to preclude or interfere with any Company's compliance with any Governmental
Requirement or require any act or omission by any Company that may be harmful to
Persons or property. Any "Material Adverse Event" or other materiality or
substantiality qualifier of any representation, warranty, covenant, agreement or
other provision of any Credit Document is included for credit documentation
purposes only and does not imply and should not be deemed to mean that
Administrative Agent or any Lender acquiesces in any non-compliance by any
Company with any applicable Governmental Requirement, document, or otherwise or
does not expect the Companies to promptly, diligently and continuously carry out
all appropriate removal, remediation, compliance, closure or other activities
required or appropriate in accordance with all Environmental Laws.
Administrative Agent's and Lenders' power is limited to the Rights provided in,
or referred to by, the Credit Documents. All of those Rights exist solely to
preserve and protect the collateral and to assure payment and performance of the
Obligation in

                                       43
<PAGE>   50

accordance with the terms of the Credit Documents, and may be exercised in a
manner determined to be appropriate by Administrative Agent or Lenders in their
sole business judgment.

         11.5 Course of Dealing. The acceptance by Administrative Agent or
Lenders of any partial payment on the Obligation is not a waiver of any Event of
Default then existing. No waiver by Administrative Agent, Required Lenders or
Lenders of any Event of Default is a waiver of any other then-existing or
subsequent Event of Default. No delay or omission by Administrative Agent,
Required Lenders or Lenders in exercising any Right under the Credit Documents
impairs that Right or is a waiver thereof or any acquiescence therein, nor will
any single or partial exercise of any Right preclude other or further exercise
thereof or the exercise of any other Right under the Credit Documents or
otherwise.

         11.6 Cumulative Rights. All Rights available to Administrative Agent,
Required Lenders and Lenders under the Credit Documents are cumulative of and in
addition to all other Rights granted to Administrative Agent, Required Lenders
and Lenders at law or in equity, whether or not the Obligation is due and
payable and whether or not Administrative Agent, Required Lenders or Lenders
have instituted any suit for collection, foreclosure, or other action in
connection with the Credit Documents.

         11.7 Application of Proceeds. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation according to Section 3.

         11.8 Certain Proceedings. Borrower shall promptly execute and deliver,
or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or Required Lenders reasonably request in connection with
the obtaining of any consent, approval, registration (other than securities law
registrations), qualification, permit, license or authorization of any
Governmental Authority or other Person necessary or appropriate for the
effective exercise of any Rights under the Credit Documents. Because Borrower
agrees that Administrative Agent's and Required Lenders' remedies under
applicable Governmental Requirements for failure of Borrower to comply with the
provisions of this section would be inadequate and that failure would not be
adequately compensable in damages, Borrower agrees that the covenants of this
section may be specifically enforced.

         11.9 Expenditures by Administrative Agent or Lenders. Any sums spent by
Administrative Agent or any Lender in the exercise of any Right under any Credit
Document is payable by the Companies to Administrative Agent within 10 days of
written demand, becomes part of the Obligation, and bears interest on the
portion thereof from time to time unpaid at the Default Rate from the date spent
until the date repaid.

SECTION 12. ADMINISTRATIVE AGENT AND LENDERS.

         12.1 Administrative Agent.

                  (a) Appointment. Each Lender appoints Administrative Agent
         (including, without limitation, each successor Administrative Agent in
         accordance with this Section 12) as its nominee and agent to act in its
         name and on its behalf (and Administrative Agent and each such
         successor accepts that appointment): (i) To act as its nominee and on
         its behalf in and under all Credit Documents; (ii) to arrange the means
         whereby its funds are to be made available to Borrower under the Credit
         Documents; (iii) to take any action that it properly requests under the
         Credit Documents (subject to the concurrence of other Lenders as may be
         required under the Credit Documents); (iv) to receive all documents and
         items to be furnished to it under the Credit Documents; (v) to promptly
         distribute to it all material information, requests, documents, and
         items received from Borrower under

                                       44
<PAGE>   51

         the Credit Documents; (vi) to promptly distribute to it its ratable
         part of each payment or prepayment (whether voluntary, as proceeds of
         collateral upon or after foreclosure, as proceeds of insurance thereon,
         or otherwise) in accordance with the terms of the Credit Documents; and
         (vii) to deliver to the appropriate Persons requests, demands,
         approvals, and consents received from it. However, Administrative Agent
         may not be required to take any action that exposes it to personal
         liability or that is contrary to any Credit Document or applicable
         Governmental Requirements.

                  (b) Successor. Administrative Agent may assign all of its
         Rights and obligations as Administrative Agent under the Credit
         Documents to any of its Affiliates, which Affiliate shall then be the
         successor Administrative Agent under the Credit Documents.
         Administrative Agent may also voluntarily resign and shall resign upon
         the request of Required Lenders for cause (i.e., Administrative Agent
         is continuing to fail to perform its responsibilities as Administrative
         Agent under the Credit Documents). If the initial or any successor
         Administrative Agent ever ceases to be a party to this agreement or if
         the initial or any successor Administrative Agent ever resigns (whether
         voluntarily or at the request of Required Lenders), then Required
         Lenders shall (which, if no Event of Default or Potential Default
         exists, is subject to Borrower's approval that may not be unreasonably
         withheld) appoint the successor Administrative Agent from among Lenders
         (other than the resigning Administrative Agent). If Required Lenders
         fail to appoint a successor Administrative Agent within 30 days after
         the resigning Administrative Agent has given notice of resignation or
         Required Lenders have removed the resigning Administrative Agent, then
         the resigning Administrative Agent may, on behalf of Lenders, appoint a
         successor Administrative Agent, which must be a commercial bank having
         a combined capital and surplus of at least $1,000,000,000 (as shown on
         its most recently published statement of condition). Upon its
         acceptance of appointment as successor Administrative Agent, the
         successor Administrative Agent succeeds to and becomes vested with all
         of the Rights of the prior Administrative Agent, and the prior
         Administrative Agent is discharged from its duties and obligations of
         Administrative Agent under the Credit Documents, and each Lender shall
         execute the documents that any Lender, the resigning or removed
         Administrative Agent, or the successor Administrative Agent reasonably
         request to reflect the change. After any Administrative Agent's
         resignation or removal as Administrative Agent under the Credit
         Documents, the provisions of this section inure to its benefit as to
         any actions taken or not taken by it while it was Administrative Agent
         under the Credit Documents.

                  (c) Rights as Lender. Administrative Agent, in its capacity as
         a Lender, has the same Rights under the Credit Documents as any other
         Lender and may exercise those Rights as if it were not acting as
         Administrative Agent. The term "Lender", unless the context otherwise
         indicates, includes Administrative Agent. Administrative Agent's
         resignation or removal does not impair or otherwise affect any Rights
         that it has or may have in its capacity as an individual Lender. Each
         Lender and Borrower agree that Administrative Agent is not a fiduciary
         for Lenders or for Borrower but is simply acting in the capacity
         described in this agreement to alleviate administrative burdens for
         Borrower and Lenders, that Administrative Agent has no duties or
         responsibilities to Lenders or Borrower except those expressly set
         forth in the Credit Documents, and that Administrative Agent in its
         capacity as a Lender has the same Rights as any other Lender.

                  (d) Other Activities. Administrative Agent or any Lender may
         now or in the future be engaged in one or more loan, letter of credit,
         leasing, or other financing transactions with Borrower, act as trustee
         or depositary for Borrower, or otherwise be engaged in other
         transactions with Borrower (collectively, the "other activities") not
         the subject of the Credit Documents. Without limiting the Rights of
         Lenders specifically set forth in the Credit Documents, neither
         Administrative Agent nor

                                       45
<PAGE>   52

         any Lender is responsible to account to the other Lenders for those
         other activities, and no Lender shall have any interest in any other
         Lender's activities, any present or future guaranties by or for the
         account of Borrower that are not contemplated by or included in the
         Credit Documents, any present or future offset exercised by
         Administrative Agent or any Lender in respect of those other
         activities, any present or future property taken as security for any of
         those other activities, or any property now or hereafter in
         Administrative Agent's or any other Lender's possession or control that
         may be or become security for the obligations of Borrower arising under
         the Credit Documents by reason of the general description of
         indebtedness secured or of property contained in any other agreements,
         documents, or instruments related to any of those other activities
         (but, if any payments in respect of those guaranties or that property
         or the proceeds thereof is applied by Administrative Agent or any
         Lender to reduce the Obligation, then each Lender is entitled to share
         ratably in the application as provided in the Credit Documents).

         12.2 Expenses. Each Lender shall pay its Pro Rata Part of any
reasonable expenses (including, without limitation, court costs, reasonable
attorneys' fees and other costs of collection) incurred by Administrative Agent
(while acting in such capacity) in connection with any of the Credit Documents
if Administrative Agent is not reimbursed from other sources within 30 days
after incurrence. Each Lender is entitled to receive its Pro Rata Part of any
reimbursement that it makes to Administrative Agent if Administrative Agent is
subsequently reimbursed from other sources.

         12.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Credit Documents, nothing in the Credit Documents gives any Lender any
advantage over any other Lender insofar as the Obligation is concerned or
relieves any Lender from ratably absorbing any losses sustained with respect to
the Obligation (except to the extent unilateral actions or inactions by any
Lender result in Borrower or any other obliger on the Obligation having any
credit, allowance, setoff, defense, or counterclaim solely with respect to all
or any part of that Lender's Pro Rata Part of the Obligation).

         12.4 Delegation of Duties; Reliance. Lenders may perform any of their
duties or exercise any of their Rights under the Credit Documents by or through
Administrative Agent, and Lenders and Administrative Agent may perform any of
their duties or exercise any of their Rights under the Credit Documents by or
through their respective Representatives. Administrative Agent, Lenders, and
their respective Representatives (a) are entitled to rely upon (and shall be
protected in relying upon) any written or oral statement believed by it or them
to be genuine and correct and to have been signed or made by the proper Person
and, with respect to legal matters, upon opinion of counsel selected by
Administrative Agent or that Lender (but nothing in this clause (a) permits
Administrative Agent to rely on (i) oral statements if a writing is required by
this agreement or (ii) any other writing if a specific writing is required by
this agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the Obligation for all purposes until, written notice
of the assignment or transfer is given to and received by Administrative Agent
(and any request, authorization, consent, or approval of any Lender is
conclusive and binding on each subsequent holder, assignee, or transferee of or
Participant in that Lender's portion of the Obligation until that notice is
given and received), (c) are not deemed to have notice of the occurrence of an
Event of Default unless a responsible officer of Administrative Agent, who
handles matters associated with the Credit Documents and transactions
thereunder, has actual knowledge or Administrative Agent has been notified by a
Lender or Borrower, and (d) are entitled to consult with legal counsel
(including counsel for Borrower), independent accountants, and other experts
selected by Administrative Agent and are not liable for any action taken or not
taken in good faith by it in accordance with the advice of counsel, accountants,
or experts.

                                       46
<PAGE>   53

         12.5 Limitation of Administrative Agent's Liability.

                  (a) Exculpation. Neither Administrative Agent nor any of its
         Affiliates or Representatives will be liable for any action taken or
         omitted to be taken by it or them under the Credit Documents in good
         faith and believed by it or them to be within the discretion or power
         conferred upon it or them by the Credit Documents or be responsible for
         the consequences of any error of judgment (except for fraud, gross
         negligence, or willful misconduct), and neither Administrative Agent
         nor any of its Affiliates or Representatives has a fiduciary
         relationship with any Lender by virtue of the Credit Documents (but
         nothing in this agreement negates the obligation of Administrative
         Agent to account for funds received by it for the account of any
         Lender).

                  (b) Indemnity. Unless indemnified to its satisfaction against
         loss, cost, liability, and expense, Administrative Agent may not be
         compelled to do any act under the Credit Documents or to take any
         action toward the execution or enforcement of the powers thereby
         created or to prosecute or defend any suit in respect of the Credit
         Documents. If Administrative Agent requests instructions from Lenders,
         or Required Lenders, as the case may be, with respect to any act or
         action in connection with any Credit Document, Administrative Agent is
         entitled to refrain (without incurring any liability to any Person by
         so refraining) from that act or action unless and until it has received
         instructions. In no event, however, may Administrative Agent or any of
         its Representatives be required to take any action that it or they
         determine could incur for it or them criminal or onerous civil
         liability. Without limiting the generality of the foregoing, no Lender
         has any right of action against Administrative Agent as a result of
         Administrative Agent's acting or refraining from acting under this
         agreement in accordance with instructions of Required Lenders.

                  (c) Reliance. Administrative Agent is not responsible to any
         Lender or any Participant for, and each Lender represents and warrants
         that it has not relied upon Administrative Agent in respect of, (i) the
         creditworthiness of any Company and the risks involved to that Lender,
         (ii) the effectiveness, enforceability, genuineness, validity, or the
         due execution of any Credit Document (except by Administrative Agent),
         (iii) any representation, warranty, document, certificate, report, or
         statement made therein (except by Administrative Agent) or furnished
         thereunder or in connection therewith, (iv) the adequacy of any
         collateral now or hereafter securing the Obligation or the existence,
         priority, or perfection of any Lien now or hereafter granted or
         purported to be granted on the collateral under any Credit Document, or
         (v) observation of or compliance with any of the terms, covenants, or
         conditions of any Credit Document on the part of any Company. EACH
         LENDER AGREES TO INDEMNIFY ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES
         AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S
         COMMITMENT PERCENTAGE OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
         DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE
         EXPENSES, AND REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER
         THAT MAY BE IMPOSED ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY
         WAY RELATING TO OR ARISING OUT OF THE CREDIT DOCUMENTS OR ANY ACTION
         TAKEN OR OMITTED BY THEM UNDER THE CREDIT DOCUMENTS IF ADMINISTRATIVE
         AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY
         ANY COMPANY. ALTHOUGH ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES HAVE
         THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN
         ORDINARY NEGLIGENCE, ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES DO
         NOT HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR
         THEIR OWN FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

                                       47
<PAGE>   54

         12.6 Event of Default. While an Event of Default exists, Lenders agree
to promptly confer in order that Required Lenders or Lenders, as the case may
be, may agree upon a course of action for the enforcement of the Rights of
Lenders. Administrative Agent is entitled to act or refrain from taking any
action (without incurring any liability to any Person for so acting or
refraining) unless and until it has received instructions from Required Lenders.
In actions with respect to any Company's property, Administrative Agent is
acting for the ratable benefit of each Lender.

         12.7 Limitation of Liability. No Lender or any Participant will incur
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither Administrative Agent nor any Lender or Participant will
incur any liability to any other Person for any act or omission of any other
Lender or any Participant.

         12.8 Relationship of Lenders. The Credit Documents do not create a
partnership or joint venture among Administrative Agent and Lenders or among
Lenders.

         12.9 Benefits of Agreement. None of the provisions of this section
inure to the benefit of any Company or any other Person except Administrative
Agent and Lenders. Therefore, no Company or any other Person is entitled to rely
upon, or entitled to raise as a defense, in any manner whatsoever, the failure
of Administrative Agent or any Lender to comply with these provisions.

SECTION 13. BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS.

         13.1 Successors and Assigns. The terms and provisions of the Credit
Documents shall be binding upon and inure to the benefit of Borrower and the
Lenders and their respective successors and assigns, except that (i) Borrower
shall not have the right to assign its rights or obligations under the Credit
Documents and (ii) any assignment by any Lender must be made in compliance with
Section 13.3. The parties to this agreement acknowledge that clause (ii) of this
Section 13.1 relates only to absolute assignments and does not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by any Lender of all or any portion of its rights under
this agreement and any Note to a Federal Reserve Bank; provided, however, that
no such pledge or assignment creating a security interest shall release the
transferor Lender from its obligations hereunder unless and until the parties
thereto have complied with the provisions of Section 13.3. The Administrative
Agent may treat the Person which made any loan or which holds any Note as the
owner thereof for all purposes hereof unless and until such Person complies with
Section 13.3; provided, however, that the Administrative Agent may in its
discretion (but shall not be required to) follow instructions from the Person
which made any loan or which holds any Note to direct payments relating to such
loan or Note to another Person. Any assignee of the rights to any loan or any
Note agrees by acceptance of such assignment to be bound by all the terms and
provisions of the Credit Documents. Any request, authority or consent of any
Person, who at the time of making such request or giving such authority or
consent is the owner of the rights to any loan (whether or not a Note has been
issued in evidence thereof), shall be conclusive and binding on any subsequent
holder or assignee of the rights to such loan.

         13.2 Participations.

                  (a) Permitted Participants; Effect. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time sell to one or more banks or other entities
         ("Participants") participating interests in any loan owing to such
         Lender, any Note held by such Lender, any Commitment of such Lender or
         any other interest of such Lender under the Credit Documents. In the
         event of any such sale by a Lender of participating interests to a
         Participant, such Lender's obligations under the Credit Documents shall
         remain unchanged, such Lender shall remain

                                       48
<PAGE>   55

         solely responsible to the other parties hereto for the performance of
         such obligations, such Lender shall remain the owner of its loans and
         the holder of any Note issued to it in evidence thereof for all
         purposes under the Credit Documents, all amounts payable by Borrower
         under this agreement shall be determined as if such Lender had not sold
         such participating interests, and Borrower and Administrative Agent
         shall continue to deal solely and directly with such Lender in
         connection with such Lender's rights and obligations under the Credit
         Documents.

                  (b) Voting Rights. Each Lender shall retain the sole right to
         approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Credit Documents other
         than any amendment, modification or waiver with respect to any loan or
         Commitment in which such Participant has an interest which forgives
         principal, interest or fees or reduces the interest rate or fees
         payable with respect to any such loan or Commitment, extends the Stated
         Termination Date, postpones any date fixed for any regularly-scheduled
         payment of principal of, or interest or fees on, any such loan or
         Commitment, releases any guarantor of any such loan or releases all or
         substantially all of the collateral, if any, securing any such loan.

                  (c) Benefit of Setoff. Borrower agrees that each Participant
         shall be deemed to have the right of setoff provided in Section 11.1 in
         respect of its participating interest in amounts owing under the Credit
         Documents to the same extent as if the amount of its participating
         interest were owing directly to it as a Lender under the Credit
         Documents, provided that each Lender shall retain the right of setoff
         provided in Section 11.1 with respect to the amount of participating
         interests sold to each Participant. The Lenders agree to share with
         each Participant, and each Participant, by exercising the right of
         setoff provided in Section 11.1, agrees to share with each Lender, any
         amount received pursuant to the exercise of its right of setoff, such
         amounts to be shared in accordance with Section 11.1 as if each
         Participant were a Lender.

         13.3 Assignments.

                  (a) Permitted Assignments. Any Lender may, in the ordinary
         course of its business and in accordance with applicable law, at any
         time assign to one or more banks or other entities ("Purchasers") all
         or any part of its rights and obligations under the Credit Documents.
         Such assignment shall be substantially in the form of Exhibit F or in
         such other form as may be agreed to by the parties thereto. The consent
         of Borrower and Administrative Agent shall be required prior to an
         assignment becoming effective with respect to a Purchaser which is not
         a Lender or an Affiliate thereof; provided, however, that if an Event
         of Default has occurred and is continuing, the consent of Borrower
         shall not be required. Such consent shall not be unreasonably withheld
         or delayed. Each such assignment with respect to a Purchaser which is
         not a Lender or an Affiliate thereof shall (unless each of Borrower and
         Administrative Agent otherwise consents) be in an amount not less than
         the lesser of (i) $5,000,000 or (ii) the remaining amount of the
         assigning Lender's Commitment (calculated as at the date of such
         assignment) or outstanding loans (if the applicable Commitment has been
         terminated).

                  (b) Effect; Effective Date. Upon (i) delivery to
         Administrative Agent of an assignment, together with any consents
         required by Section 13.3(a), and (ii) payment of a $4,000 fee from the
         Purchaser or the assigning Lender to Administrative Agent for
         processing such assignment (unless such fee is waived by Administrative
         Agent), such assignment shall become effective on the effective date
         specified in such assignment. The assignment shall contain a
         representation by the Purchaser to the effect that none of the
         consideration used to make the purchase of the Commitment and loans
         under the applicable assignment agreement constitutes "plan assets" as
         defined under ERISA and that

                                       49
<PAGE>   56

         the rights and interests of the Purchaser in and under the Credit
         Documents will not be "plan assets" under ERISA. On and after the
         effective date of such assignment, such Purchaser shall for all
         purposes be a Lender party to this agreement and any other Credit
         Document executed by or on behalf of the Lenders and shall have all the
         rights and obligations of a Lender under the Credit Documents, to the
         same extent as if it were an original party hereto, and no further
         consent or action by Borrower, the Lenders or Administrative Agent
         shall be required to release the transferor Lender with respect to the
         percentage of the Commitment and loans assigned to such Purchaser. Upon
         the consummation of any assignment to a Purchaser pursuant to this
         Section 13.3(b), the transferor Lender, Administrative Agent and
         Borrower shall, if the transferor Lender or the Purchaser desires that
         its loans be evidenced by Notes, make appropriate arrangements so that
         new Notes or, as appropriate, replacement Notes are issued to such
         transferor Lender and new Notes or, as appropriate, replacement Notes,
         are issued to such Purchaser, in each case in principal amounts
         reflecting their respective Commitments, as adjusted pursuant to such
         assignment.

         13.4 Dissemination of Information. Borrower authorizes each Lender to
disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Credit Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of Borrower and its Subsidiaries, so long as
such Transferee or prospective Transferee agrees in writing to keep such
information confidential.

         13.5 Tax Treatment. If any interest in any Credit Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.19.

SECTION 14. MISCELLANEOUS.

         14.1 Nonbusiness Days. Any payment or action that is due under any
Credit Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a LIBOR Rate
Borrowing, in which case if the next-succeeding Business Day is in the next
calendar month, then such payment shall be made on the next-preceding Business
Day.

                                       50
<PAGE>   57

         14.2 Communications. Unless otherwise specifically provided, whenever
any Credit Document requires or permits any consent, approval, notice, request
or demand from one party to another, com munication must be in writing (which
may be by telex or fax) to be effective and shall be deemed to have been given
(i) if by telex, when transmitted to the appropriate telex number and the
appropriate answer back is received, (ii) if by fax, when transmitted to the
appropriate fax number and machine confirmation of receipt is received (and all
communications sent by fax must be confirmed promptly thereafter by telephone;
but any requirement in this parenthetical shall not affect the date when the fax
shall be deemed to have been delivered), (iii) if by mail, on the third Business
Day after it is enclosed in an envelope and properly addressed, stamped, sealed
and deposited in the appropriate official postal service, (iv) if by e-mail,
when transmitted to the appropriate e-mail address of the receiving party ( and
all communications sent by e-mail must be followed by a facsimile of that e-mail
sent to the receiving party), or (v) if by any other means, when actually
delivered. Until changed by notice pursuant to this agreement, the addresses
(and fax numbers) for Borrower, and Administrative Agent are stated beside their
respective signatures to this agreement. The address (and fax number) for each
Lender who becomes party to this agreement shall be stated beside its name on
the then most recently amended Schedule 2.

         14.3 Form and Number of Documents. The form, substance and number of
counterparts of each writing to be furnished under this agreement must be
satisfactory to Administrative Agent and its counsel.

         14.4 Exceptions to Covenants. No Company may take or fail to take any
action that is permitted as an exception to any of the covenants contained in
any Credit Document if that action or omission would result in the breach of any
other covenant contained in any Credit Document.

         14.5 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Credit Documents survive all
closings under the Credit Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

         14.6 Governing Governmental Requirements. Unless otherwise stated in
any Credit Document, the Governmental Requirements of the State of Texas and of
the United States of America govern the Rights and duties of the parties to the
Credit Documents and the validity, construction, enforcement, and interpretation
of the Credit Documents.

         14.7 Invalid Provisions. Any provision in any Credit Document held to
be illegal, invalid or unenforceable is fully severable; the appropriate Credit
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. Administrative Agent, Lenders
and each Company party to the affected Credit Document agree to negotiate, in
good faith, the terms of a replacement provision as similar to the severed
provision as may be possible and be legal, valid and enforceable.

         14.8 Conflicts Between Credit Documents. The provisions of this
agreement control if in conflict (i.e., the provisions contradict each other as
opposed to a Credit Document containing additional provisions not in conflict)
with the provisions of any other Credit Document.

         14.9 Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances. Each Company's obligations under the Credit Documents shall
remain in full force and effect until termination of the Commitment and payment
in full of the Principal Debt and of all interest, fees, and other amounts of
the Obligation then due and owing, except that Sections 3.16, 3.18, Section 11,
and Section 13, and any other provisions under the Credit Documents expressly
intended to survive by the terms hereof or by the terms of the applicable Credit
Documents, shall survive such termination. If at any time any payment of the
principal

                                       51
<PAGE>   58

of or interest on any Note or any other amount payable by Borrower under any
Credit Document is rescinded or must be otherwise restored or returned upon the
insolvency, bankruptcy, or reorganization of Borrower or otherwise, the
obligations of each Company under the Credit Documents with respect to such
payment shall be reinstated as though such payment had been due but not made at
such time.

         14.10 Amendments, Consents, Conflicts, and Waivers.

                  (a) Required Lenders. Unless otherwise specifically provided
         (i) the provisions of this agreement may be amended, modified, or
         waived, only by an instrument in writing executed by Borrower,
         Administrative Agent, and Required Lenders and supplemented only by
         documents delivered or to be delivered in accordance with the express
         terms of this agreement, and (ii) the other Credit Documents may only
         be the subject of an amendment, modification, or waiver that has been
         approved by Required Lenders and Borrower.

                  (b) All Lenders. Any amendment to or consent or waiver under
         this agreement or any Credit Document that purports to accomplish any
         of the following must be by an instrument in writing executed by
         Borrower and Administrative Agent and executed (or approved, as the
         case may be) by each Lender: (i) Extends the due date or decreases the
         amount of any scheduled payment or amortization of the Obligation
         beyond the date specified in the Credit Documents; (ii) decreases any
         rate or amount of interest, fees, or other sums payable to
         Administrative Agent or Lenders under this agreement (except such
         reductions as are contemplated by this agreement); (iii) changes the
         definition of "Commitment," "Commitment Percentage," "Required
         Lenders," or "Pro Rata Part;" (iv) increases any one or more Lenders'
         Commitment; or (v) changes this clause (b) or any other matter
         specifically requiring the consent of all Lenders under this agreement.

                  (c) Conflicts. Any conflict or ambiguity between the terms and
         provisions of this agreement and terms and provisions in any other
         Credit Document is controlled by the terms and provisions of this
         agreement.

                  (d) Waivers. No course of dealing or any failure or delay by
         Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of Administrative
         Agent or any Lender under this agreement operates as a waiver thereof.
         A waiver must be in writing and signed by Administrative Agent and
         Lenders (or Required Lenders, if permitted under this agreement) to be
         effective, and a waiver will be effective only in the specific instance
         and for the specific purpose for which it is given.

         14.11 Multiple Counterparts. Any Credit Document may be executed in a
number of identical counterparts, and by each party thereto on separate
counterparts (including, at Administrative Agent's discretion, counterparts or
signature pages executed and transmitted by fax) with the same effect as if all
signatories had signed the same document. All counterparts must be construed
together to constitute one and the same instrument.

         14.12 VENUE, SERVICE OF PROCESS, AND JURY TRIAL.

                  (A) VENUE AND SERVICE OF PROCESS. BORROWER, FOR ITSELF AND ITS
         SUCCESSORS AND ASSIGNS, IRREVOCABLY (i) SUBMITS TO THE NONEXCLUSIVE
         JURISDICTION OF THE STATE AND FEDERAL COURTS IN TEXAS, (ii) WAIVES, TO
         THE FULLEST EXTENT PERMITTED BY APPLICABLE GOVERNMENTAL REQUIREMENTS,
         ANY OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE TO THE LAYING OF
         VENUE OF ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH ANY CREDIT

                                       52
<PAGE>   59

         DOCUMENT AND THE OBLIGATION BROUGHT IN THE DISTRICT COURTS OF DALLAS
         COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
         DISTRICT OF TEXAS, DALLAS DIVISION, (iii) WAIVES ANY CLAIMS THAT ANY
         LITIGATION BROUGHT IN ANY OF THE FOREGOING COURTS HAS BEEN BROUGHT IN
         AN INCONVENIENT FORUM, (iv) CONSENTS TO THE SERVICE OF
         PROCESS OF ANY OF THOSE COURTS IN ANY LITIGATION BY THE MAILING OF
         COPIES OF THAT PROCESS BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED,
         POSTAGE PREPAID, BY HAND DELIVERY, OR BY DELIVERY BY A NATIONALLY
         RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE DEEMED COMPLETE UPON
         DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS FOR PURPOSES OF THIS
         AGREEMENT, AND (v) AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY
         TO ANY CREDIT DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE CREDIT
         DOCUMENTS OR THE OBLIGATION MAY BE BROUGHT IN ONE OF THE FOREGOING
         COURTS.

                  (b) JURY WAIVER. EACH OF BORROWER, ADMINISTRATIVE AGENT,
         ARRANGER AND EACH LENDER HEREBY VOLUNTARILY, KNOWINGLY, IRREVOCABLY AND
         UNCONDITIONALLY WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN
         RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE)
         BETWEEN OR AMONG SUCH PARTIES ARISING OUT OF OR IN ANY WAY RELATED TO
         THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT. THIS PROVISION IS A
         MATERIAL INDUCEMENT TO LENDERS TO PROVIDE THE FINANCING DESCRIBED
         HEREIN OR IN THE OTHER CREDIT DOCUMENTS.

                  (c) General. The scope of each of the foregoing waivers is
         intended to be all encompassing of any and all disputes that may be
         filed in any court and that relate to the subject matter of this
         transaction, including, without limitation, contract claims, tort
         claims, breach of duty claims, and all other common law and statutory
         claims. BORROWER ACKNOWLEDGES THAT THESE WAIVERS ARE A MATERIAL
         INDUCEMENT TO ADMINISTRATIVE AGENT'S, ARRANGER'S AND EACH LENDER'S
         AGREEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH OF
         ADMINISTRATIVE AGENT, ARRANGER AND EACH LENDER HAVE ALREADY RELIED ON
         THESE WAIVERS IN ENTERING INTO THIS AGREEMENT, AND THAT ADMINISTRATIVE
         AGENT, ARRANGER AND EACH LENDER WILL CONTINUE TO RELY ON EACH OF THESE
         WAIVERS IN RELATED FUTURE DEALINGS. BORROWER FURTHER WARRANTS AND
         REPRESENTS THAT IT HAS REVIEWED THESE WAIVERS WITH ITS LEGAL COUNSEL,
         AND THAT IT KNOWINGLY AND VOLUNTARILY AGREES TO EACH WAIVER FOLLOWING
         CONSULTATION WITH LEGAL COUNSEL. The waivers in this section are
         irrevocable, meaning that they may not be modified either orally or in
         writing, and these waivers apply to any future renewals, extensions,
         amendments, modifications, or replacements in respect of the applicable
         Credit Document. In connection with any Litigation, this agreement may
         be filed as a written consent to a trial by the court.

         14.13 Arbitration. Borrower, Administrative Agent, Arranger and each
Lender agree that upon the written demand of any such party, whether made before
or after the institution of any legal proceedings, but prior to the rendering of
any judgment in that proceeding, all disputes, claims and controversies between
them, whether individual, joint, or class in nature, arising from this
agreement, any other Credit Document, or otherwise, including without limitation
contract disputes and tort claims, shall be resolved by binding arbitration
pursuant to the Commercial Rules of the American Arbitration Association
("AAA"). Any arbitration proceeding held pursuant to this arbitration provision
shall be conducted in the city nearest the Borrower's address having an AAA
regional office, or at any other place selected by mutual agreement of the
parties. No act to take or dispose of any collateral shall constitute a waiver
of this arbitration agreement or be prohibited by this arbitration agreement.
This arbitration provision shall not limit the right of any party during any
dispute, claim or controversy to seek, use, and employ ancillary, or preliminary
rights and/or remedies, judicial or otherwise, for the purposes of realizing
upon, preserving, protecting, foreclosing upon

                                       53
<PAGE>   60

or proceeding under forcible entry and detainer for possession of, any real or
personal property, and any such action shall not be deemed an election of
remedies. Such remedies include, without limitation, obtaining injunctive relief
or a temporary restraining order, invoking a power of sale under any deed of
trust or mortgage, obtaining a writ of attachment or imposition of a
receivership, or exercising any rights relating to personal property, including
exercising the right of set-off, or taking or disposing of such property with or
without judicial process pursuant to the Uniform Commercial Code. Any disputes,
claims or controversies concerning the lawfulness or reasonableness of an act,
or exercise of any right or remedy concerning any collateral, including any
claim to rescind, reform or otherwise modify any agreement relating to the
collateral, shall also be arbitrated; provided, however, that no arbitrator
shall have the right or the power to enjoin or restrain any act of any party.
Judgment upon any award rendered by any arbitrator may be entered in any court
having jurisdiction. The statute of limitations, estoppel, waiver, laches and
similar doctrines which would otherwise be applicable in an action brought by a
party shall be applicable in any arbitration proceeding, and the commencement of
an arbitration proceeding shall be deemed the commencement of any action for
these purposes. The Federal Arbitration Act (Title 9 of the United States Code)
shall apply to the construction, interpretation, and enforcement of this
arbitration provision.

         14.14 Entirety. THE CREDIT DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN BORROWER, THE OTHER COMPANIES, LENDERS, AND ADMINISTRATIVE AGENT AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

         14.15 Restatement of Existing Agreement. The parties hereto agree that,
on the Closing Date, after all conditions precedent set forth in Section 5.1
have been satisfied or waived: (a) the Obligation (as defined herein)
represents, among other things, the amendment, extension, consolidation, and
modification of the obligations and liabilities of Borrower under or in respect
of the Existing Agreement; (b) this agreement is intended to, and does hereby,
restate, consolidate, renew, extend, amend, modify, supersede, and replace the
Existing Agreement in its entirety; (c) the Notes, if any, executed pursuant to
this agreement amend, renew, extend, modify, replace, substitute for, and
supersede in their entirety (but do not extinguish), the Debt arising under the
promissory notes to the Existing Agreement, if any, which existing promissory
notes shall be returned to Borrower promptly after the Closing Date, marked
"cancelled and replaced"; and (d) the entering into and performance of their
respective obligations under this agreement and the transactions evidenced
hereby do not constitute a novation.
