SECTION 2  COMMITMENT.
- ---------  ---------- 

     2.1  Revolving Facility. Subject to the provisions of this Agreement, each
Lender severally and not jointly agrees to lend to Borrower one or more
Borrowings (except for Competitive Borrowings and Swing Line Loans) hereunder
which Borrower may borrow, repay, and reborrow under this Agreement, subject to
the following conditions:

     (a) each Borrowing requested by Borrower hereunder must occur on a Business
Day and no later than the Business Day immediately preceding the Termination
Date;

     (b) each Borrowing requested by Borrower must be in an amount not less than
$1,000,000 or a greater integral multiple of $100,000 or, if less, the Unused
Commitment less the Principal Debt of any Swing Line Loans;

     (c) the Total Principal Debt may not exceed the Total Commitment; and

     (d) no Lender's Principal Debt (other than the Principal Debt of such
Lender's Competitive Borrowings) may exceed such Lender's Commitment.

                                       18
<PAGE>
 
     2.2 Borrowing Procedure.  The following procedures apply to Borrowings
(other than Competitive Borrowings and Swing Line Loans):

     (a) Borrower may request a Borrowing by submitting to Administrative Agent
a Borrowing Request.  The Borrowing Request must be received by Administrative
Agent no later than 11:00 a.m. on (i) the third (3rd) Business Day preceding the
Borrowing Date for any Eurodollar Borrowing or (ii) the Business Day preceding
the Borrowing Date for any Base Rate Borrowing.  Administrative Agent shall
promptly notify each Lender of its receipt of any Borrowing Request and its
contents.  A Borrowing Request is irrevocable and binding on Borrower.

     (b) By 11:00 a.m. on the applicable Borrowing Date, each Lender shall remit
its Pro Rata Part of each requested Borrowing by wire transfer to Administrative
Agent pursuant to Administrative Agent's wire transfer instructions on Schedule
1 (or as otherwise directed by Administrative Agent) in funds that are available
for immediate use by Administrative Agent.  Subject to receipt of such funds,
Administrative Agent shall make such funds available to Borrower in Dallas,
Texas at 12:00 noon on such Borrowing Date (unless it has actual knowledge that
any applicable condition precedent has not been satisfied by Borrower).

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

     2.3 Termination.  Without premium or penalty, and upon giving at least
three (3) Business Days prior written and irrevocable notice to Administrative
Agent, Borrower may terminate all or part of the unused portion of the Total
Commitment, provided that Borrower may not partially terminate the unused
portion of the Total Commitment such that the Total Commitment is less than
$300,000,000.  Each partial termination must be in an amount of not less than
$1,000,000 or a greater integral multiple of $1,000,000, and shall be Pro Rata
among all Lenders.  Once terminated, the Total Commitment may not be increased
or reinstated.

      2.4 Swing Line Subfacility.

     (a) Subject to the terms and conditions hereof, if necessary to meet
Borrower's funding deadlines, NationsBank agrees to make Swing Line Loans to
Borrower at any time on or prior to the Swing Line Maturity Date, not to exceed
an amount at any one time outstanding equal to the lesser of (i) $75,000,000,
and (ii) the difference between the Total Commitment and the Total Principal
Debt.  Swing Line Loans shall constitute "Borrowings" for all purposes
hereunder, except that Swing Line Loans shall not be considered a utilization of
any Lender's Commitment.  Notwithstanding the foregoing, the Total Principal

                                       19
<PAGE>
 
Debt (including, without limitation, all Swing Line Loans) shall not at any time
exceed the Total Commitment.

     (b) Each request for a Swing Line Loan shall be in an amount equal to
$1,000,000 or a greater integral multiple of $50,000.  Borrower may request a
Swing Line Loan by submitting a Borrowing Request to Administrative Agent and
NationsBank.  Such Borrowing Request must be received by Administrative Agent
and NationsBank no later than 11:00 a.m. on the Borrowing Date for such Swing
Line Loan, provided that Borrower shall have provided telephonic notice to
Administrative Agent and NationsBank no later than 11:00 a.m. on the Borrowing
Date for such Swing Line Loan.  NationsBank shall make such Swing Line Loan
available to Borrower in Dallas, Texas at 1:00 p.m. on such Borrowing Date.

     (c) Upon the occurrence of a Default or in the event that any Swing Line
Loan shall be outstanding for more than five (5) Business Days,  Administrative
Agent shall, on behalf of Borrower (which hereby irrevocably directs and
authorizes Administrative Agent to act on its behalf), request a Base Rate
Borrowing from Lenders (and each Lender shall fund its Pro Rata Part thereof) in
an amount sufficient to repay the Principal Debt outstanding under such Swing
Line Loan; provided that, such Borrowing shall be made notwithstanding
Borrower's noncompliance with Section 5.  The proceeds of such Borrowing shall
be immediately applied to repay such Swing Line Loan.  If, for any reason, a
Borrowing may not be (as determined by Administrative Agent in its sole
discretion), or is not, made pursuant to this Section 2.4(c) to repay any Swing
Line Loan as required hereby, then, effective on the date such Borrowing would
otherwise have been made, each Lender severally, unconditionally, and
irrevocably agrees that it shall be deemed to have purchased an undivided
participating interest in such Swing Line Loan (an "Unrefunded Swing Line
Borrowing") to the extent of such Lender's Pro Rata Part thereof.  Each Lender
shall fund a Borrowing or a participation in the Unrefunded Swing Line
Borrowings no later than the close of business on the date notice of such
funding requirement is given by Administrative Agent if such notice was given
prior to 11:00 a.m. on any Business Day, or if made at any other time, on the
next Business Day following the date of such notice. All such amounts payable by
any Lender under this Section 2.3(c) shall include interest thereon from the
date on which such payment is payable by such Lender to, but not including, the
date such amount is paid by such Lender to Administrative Agent, at the Federal
Funds Rate.  If such Lender does not promptly pay such amount upon
Administrative Agent's demand therefor, and until such time as such Lender makes
the required payment, NationsBank shall be deemed to continue to have
outstanding its ratable portion of the Principal Debt of such Swing Line Loan in
the amount of such unpaid obligation.  Each payment by Borrower of all or any
part of any Swing Line Loan shall be paid to Administrative Agent for the
benefit of NationsBank and those Lenders who hold funded participations in such
Swing Line Loan under this Section 2.4(c); provided that with respect to any
such participation, all interest on the Principal Debt of such Swing Line Loan
to which such participation relates accruing prior to the date of funding such
participation, shall be payable solely to Administrative Agent for the account
of NationsBank (and all Lenders holding funded participations in any Unrefunded
Swing Line Borrowing prior to such date).  Any Lender holding a participation in
any Unrefunded Swing Line Borrowing may exercise any and all Rights of banker's
lien, setoff, or counterclaim with respect to any and all moneys owing by
Borrower to such Lender by reason thereof as fully as if such Lender had
extended such Borrowing directly to Borrower in the amount of such
participation.  Whenever, at any time after NationsBank has received from any
Lender such Lender's participating interest in any Swing Line Loan, NationsBank
receives any payment on account thereof, NationsBank will promptly distribute to
such Lender its participating interest in such amount (appropriately adjusted,
in the case of interest payments, to reflect the period of time during which
such Lender's participating interest was outstanding and funded); provided,
however, that in the event that such payment received by NationsBank is required
to be returned, such Lender will return to NationsBank any portion thereof
previously distributed by NationsBank to it.

                                       20
<PAGE>
 
     (d) Unless Administrative Agent knew when NationsBank funded a Swing Line
Loan that Borrower had not satisfied the conditions in this Agreement to obtain
a Borrowing, each Lender's obligation to purchase an interest in all Swing Line
Loans shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation (i) any set-off, counterclaim,
recoupment, defense, or other right which such Lender or any other Person may
have against NationsBank or any other Person for any reason whatsoever, (ii) the
occurrence or continuance of a Potential Default or Default or the termination
of any Lender's Commitment, (iii) the occurrence of any Material Adverse Event,
(iv) any breach of this Agreement or any other Loan Document by Borrower, any of
its Affiliates, Administrative Agent, or any other Lender, or (v) any other
circumstance, happening, or event whatsoever, whether or not similar to any of
the foregoing. Any portion of a Swing Line Loan not so purchased and converted
may be treated by NationsBank as a Borrowing which was not funded by the non-
purchasing Lenders as contemplated in Section 2.2(c) of this Agreement, and as a
funding by NationsBank under the Total Commitment in excess of NationsBank's
Commitment.  Each Swing Line Loan, once so sold, shall cease to be a Swing Line
Loan for the purposes of this Agreement, but shall be a Borrowing made under the
Total Commitment and each Lender's Commitment.

     2.5 Competitive Bid Subfacility.

     (a) In addition to Borrowings otherwise provided for herein, but subject to
the terms and conditions of the Loan Documents, Borrower may, as set forth in
this Section 2.5, request Lenders to make offers to make Competitive Borrowings
under the Total Commitment.  Lenders may, but shall have no obligation to, make
any such offers, and Borrower may, but shall have no obligation to, accept any
such offers. Any Competitive Borrowings made available to Borrower hereunder
shall be subject, however, to the conditions that on the Borrowing Date
therefor:  (i) the Moody's Rating is Baa3 or better and the S & P Rating is BBB-
or better; (ii) the aggregate principal outstanding under all Competitive
Borrowings made by all Lenders shall not exceed $175,000,000; and (iii) the
Principal Debt of all Borrowings (whether under the Competitive Bid Subfacility,
the Swing Line Subfacility, or otherwise) shall not exceed the Total Commitment.
Each Borrowing under the Competitive Bid Subfacility must occur on a Business
Day and prior to the Business Day immediately preceding the Termination Date.

     (b) In order to request Competitive Bids, Borrower shall deliver a
Competitive Bid Request to Administrative Agent no later than (i) 10:00 a.m.
Dallas, Texas time on the fifth (5th) Business Day preceding the Borrowing Date
for any requested Competitive Borrowing that will be comprised of Eurodollar
Borrowings, or (ii) 9:00 a.m. Dallas, Texas time one (1) Business Day before the
Borrowing Date for any requested Competitive Borrowing that will be comprised of
Fixed Rate Borrowings.  A Competitive Bid Request that does not conform
substantially to the format of Exhibit B-2 may be rejected by Administrative
Agent, and Administrative Agent shall promptly notify Borrower of such
rejection.  Each Competitive Bid Request shall refer to this Agreement and shall
specify (i) whether the Competitive Borrowing then being requested will be
comprised of Eurodollar Borrowings or Fixed Rate Borrowings, (ii) the Borrowing
Date of such Competitive Borrowing (which shall be a Business Day) and the
aggregate principal amount thereof (which shall be $10,000,000 or a greater
integral multiple of $1,000,000), and (iii) the Interest Period with respect
thereto (which may not be more than six (6) months and which may not extend
beyond the Termination Date). Promptly after its receipt of a Competitive Bid
Request that is not rejected as aforesaid, Administrative Agent shall notify
Lenders of the Competitive Bid Request on a form substantially similar to
Exhibit B-2, pursuant to which Lenders are invited to bid, subject to the terms
and conditions of this Agreement, to make Competitive Borrowings pursuant to
such Competitive Bid Request.  Notwithstanding the foregoing, Administrative
Agent shall have no obligation to invite any Lender to make a Competitive

                                       21
<PAGE>
 
Bid pursuant to this Section 2.5 until such Lender has delivered a completed
administrative questionnaire to Administrative Agent.

     (c) Each Lender may make one (1) or more Competitive Bids to Borrower
responsive to each respective Competitive Bid Request.  Each Competitive Bid by
a Lender must be substantially in the form of Exhibit F and must be received by
Administrative Agent (i) no later than 11:00 a.m. Dallas, Texas time on the
fourth (4th) Business Day preceding the Borrowing Date for any requested
Competitive Borrowing that will be comprised of Eurodollar Borrowings, or (ii)
prior to 9:00 a.m. Dallas, Texas time on the Borrowing Date for any requested
Competitive Borrowing that will be comprised of Fixed Rate Borrowings.
Competitive Bids that do not conform substantially to the format of Exhibit F
may be rejected by Administrative Agent after conferring with, and upon the
instruction of, Borrower, and Administrative Agent shall notify the appropriate
Lender of such rejection as soon as practicable.  Each Competitive Bid shall
refer to this Agreement and shall (x) specify the principal amount (which shall
be $5,000,000 or a greater integral multiple of $1,000,000 and which may equal
the entire principal amount of the Competitive Borrowing requested by Borrower
and may exceed such Lender's Commitment, subject to the limitations set forth in
Section 2.5(a)) of the Competitive Borrowing such Lender is willing to make to
Borrower, (y) specify the Competitive Bid Rate at which such Lender is prepared
to make its Competitive Borrowing, and (z) confirm the Interest Period with
respect thereto specified by Borrower in its Competitive Bid Request.  A
Competitive Bid submitted by a Lender pursuant to this Section 2.5(c) shall be
irrevocable.

     (d) Administrative Agent shall promptly notify Borrower of all Competitive
Bids made and the Competitive Bid Rate and the principal amount of each
Competitive Borrowing in respect of which a Competitive Bid was made and the
identity of the Lender that made each bid.

     (e) Borrower may, subject only to the provisions of this Section 2.5(e),
accept or reject any or all of the Competitive Bids referred to in Section
2.5(c); provided, however, that the aggregate amount of the Competitive Bids so
accepted by Borrower may not exceed the principal amount of the Competitive
Borrowing requested by Borrower (subject to the further limitations of Section
2.5(a)).  Borrower shall notify Administrative Agent whether and to what extent
it has decided to accept or reject any or all of the bids referred to in Section
2.5(c) (i) not later than 10:00 a.m. Dallas, Texas time three (3) Business Days
before the Borrowing Date specified for a proposed Competitive Borrowing that is
deemed a Eurodollar Borrowing or (ii) not later than 10:00 a.m., Dallas, Texas
time on the day specified for a proposed Competitive Borrowing that is deemed a
Fixed Rate Borrowing; provided, however, that (A) the failure by Borrower to
give such notice shall be deemed to be a rejection of all the bids referred to
in Section 2.5(c), (B) Borrower shall not accept a bid in the same or lower
principal amount made at a particular Competitive Bid Rate if Borrower has
decided to reject a bid made at a lower Competitive Bid Rate, (C) if Borrower
shall accept bids made at a particular Competitive Bid Rate but shall be
restricted by other conditions hereof from borrowing the principal amount of the
Competitive Borrowing in respect of which bids at such Competitive Bid Rate have
been made, then Borrower shall accept a ratable portion of each bid made at such
Competitive Bid Rate based as nearly as possible on the respective principal
amounts of the Competitive Borrowing for which such bids were made, and (D) no
bid shall be accepted for a Competitive Borrowing unless the aggregate principal
amount to be funded pursuant to all accepted bids hereunder shall be in a
minimum amount of $10,000,000 and the amount to be funded by each Lender whose
bid is accepted is $5,000,000 or a greater integral multiple of $1,000,000.
Notwithstanding the foregoing, if it is necessary for Borrower to accept a
ratable allocation of the bids made in response to a Competitive Bid Request
(whether pursuant to the events specified in clause (C) above or otherwise) and
the available principal amount of the Competitive Borrowing to be allocated
among the Lenders submitting Competitive Bids is not sufficient to enable
Competitive Borrowings to be allocated to each such Lender in a minimum
principal amount of

                                       22
<PAGE>
 
$5,000,000 or a greater integral multiple of $1,000,000, then Borrower shall
select the Lenders to be allocated such Competitive Borrowings and shall round
allocations up or down to the next higher or lower multiple of $500,000 as it
shall deem appropriate. A notice given by Borrower pursuant to this Section
2.5(e) shall be irrevocable.

     (f) Administrative Agent shall promptly notify each bidding Lender whether
or not its Competitive Bid has been accepted (which notice to such Lenders whose
Competitive Bids have been accepted will be given within one (1) hour (except in
the case of Fixed Rate Borrowings, in which case as soon as possible) from the
time such bid was accepted by Borrower and shall further indicate in what amount
and at what Competitive Bid Rate), and each successful bidder will be obligated,
subject to the other applicable conditions hereof, to advance the Competitive
Borrowing in respect of which its bid has been accepted.  After completing the
notifications referred to in the immediately preceding sentence, Administrative
Agent shall notify each bidding Lender of the aggregate principal amount of all
Competitive Bids accepted for and the range of Competitive Bid Rates submitted
in connection with that Competitive Borrowing.

     (g) If Administrative Agent shall at any time elect to submit a Competitive
Bid in its capacity as a Lender, then it shall submit such bid directly to
Borrower one-half hour earlier than the latest time at which the other Lenders
are required to submit their bids to Administrative Agent pursuant to Section
2.5(c).

     (h) The Principal Debt of each Competitive Borrowing and all unpaid
interest thereon shall be due and payable on the last day of the applicable
Interest Period; provided that if Borrower fails to repay any Competitive
Borrowing on such day, then Borrower shall be deemed to have given a Notice of
Borrowing requesting Lenders to make a Borrowing hereunder in the amount of such
Competitive Borrowing, subject to satisfaction of the conditions specified in
Section 5; provided that failure to repay such Competitive Borrowing on the last
day of the applicable Interest Period shall not constitute a failure to satisfy
such conditions.

     2.6 Lenders.

     (a) Initial Lenders.  The Lenders on the Closing Date shall be the Lenders
set forth on Schedule 1 attached hereto on the Closing Date.

     (b) Subsequent Lenders.  After the Closing Date until June 30, 1999,
Administrative Agent may, from time to time, (i) admit additional Lenders
hereunder (each a "Subsequent Lender"), or (ii) at the request of any Lender
increase the Commitment of such Lender (each an "Increasing Lender"), subject to
the following conditions:

          (i)    Each Subsequent Lender is (A) an Eligible Assignee, and (B)
     approved by Borrower, such approval not to be unreasonably withheld;

          (ii)   Borrower executes (A) new Notes payable to the order of a
     Subsequent Lender, or (B) a replacement Note payable to the order of an
     Increasing Lender;

          (iii)  Borrower pays all fees payable pursuant to Section 4 and the
     fee letter(s) described therein;

          (iv)   Each Subsequent Lender executes a signature page to this
     Agreement;

                                       23
<PAGE>
 
          (v)    After giving effect the admission of any Subsequent Lender or
     the increase in the Commitment of any Increasing Lender, the aggregate face
     amount of the Total Commitment does not exceed $550,000,000; and

          (vi)   No admission of any Subsequent Lender shall increase the
     Commitment of any existing Lender.

After the admission of any Subsequent Lender or the increase in the Term Loan of
any Increasing Lender, Administrative Agent shall provide to each Lender a new
Schedule 1 to this Agreement.

SECTION 3   TERMS OF PAYMENT.
- ---------   ---------------- 

     3.1   Notes and Payments.

     (a) The Principal Debt (other than Competitive Borrowings and Swing Line
Loans) shall be evidenced by the Revolving Credit Notes, one payable to each
Lender in the stated principal amount of its Commitment.  The Principal Debt of
all Competitive Borrowings shall be evidenced by the Competitive Bid Notes.  The
Principal Debt of all Swing Line Loans shall be evidenced by the Swing Line
Note.

     (b) Borrower must make each payment and prepayment on the Obligation,
without offset, counterclaim, or deduction, to Administrative Agent's principal
office in Dallas, Texas, in funds that will be available for immediate use by
Administrative Agent by 12:00 noon on the day due.  Payments received after such
time shall be deemed received on the next Business Day.  Administrative Agent
shall pay to each Lender any payment to which such Lender is entitled on the
same day Administrative Agent receives the funds from Borrower if Administrative
Agent receives the payment before 12:00 noon, and otherwise before 12:00 noon on
the following Business Day.  If and to the extent that Administrative Agent does
not make payments to Lenders when due, then unpaid amounts shall accrue interest
at the Federal Funds Rate from the due date until (but not including) the
payment date.

     3.2 Interest and Principal Payments.

     (a) Interest Payments.  Accrued interest on each Borrowing (other than
Competitive Borrowings) is due and payable monthly as it accrues on the first
(1st) day of each month during the term hereof (commencing on May 1, 1999) and
on the Termination Date.  Accrued interest on each Competitive Borrowing is due
and payable on the last day of its respective Interest Period; provided that if
any such Interest Period is a period greater than three (3) months, then accrued
interest on such Competitive Borrowing shall also be due and payable on the date
ending each three (3) month period after the commencement of such Interest
Period.

     (b) Principal Payments.  The Total Principal Debt is due and payable on the
Termination Date.

     (c) Voluntary Prepayment.  Borrower may voluntarily prepay all or any part
of the Total Principal Debt at any time without premium or penalty, subject to
the following conditions:

          (i)    Administrative Agent must receive Borrower's written prepayment
     notice by 11:00 a.m. on the Business Day preceding the date of prepayment,
     which notice shall specify the payment date and the Type and amount of the
     Borrowing(s) to be paid, and which shall constitute an irrevocable and
     binding obligation of Borrower to make a prepayment on the designated date;

                                       24
<PAGE>
 
          (ii)   each partial prepayment must be in the amount of $1,000,000 or
     a greater integral multiple of $100,000, or, if less, the Total Principal
     Debt; and

          (iii)  Borrower shall pay any related Funding Loss upon demand.

Notwithstanding anything contained herein to the contrary, Borrower shall not
voluntarily prepay any Competitive Borrowing prior to the last day of the
Interest Period therefor.

Borrowings (other than Competitive Borrowings and Swing Line Loans) shall bear
interest at an annual rate equal to the lesser of (a) the Base Rate plus the
Applicable Margin, or the Eurodollar Rate plus the Applicable Margin (in each
case as designated or deemed designated by Borrower and, in the case of
Eurodollar Borrowings, for the Interest Period designated by Borrower), and (b)
the Maximum Rate.  Except as specifically otherwise provided, Competitive
Borrowings shall bear interest at an annual rate of interest equal to the lesser

Margin, and (B) the Maximum Rate.  Each change in the Base Rate, Money Market
Rate, or Maximum Rate is effective, without notice to Borrower or any other
Person, upon the effective date of such change.

     3.4 Quotation of Rates.  A Representative of 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 any Credit Party or affect the interest rate that is actually in effect
when Borrower delivers its Borrowing Request or on the Borrowing Date.

     3.5 Default Rate.  If permitted by Law, all past-due Principal Debt and
past-due interest shall bear interest from the date due (stated or by
acceleration) at the Default Rate until paid, regardless 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, then 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 permitted by applicable Law, 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.

     (a) Interest will be calculated on the basis of actual number of days
elapsed (including the first day but excluding the last day) but computed as if
each calendar year consisted of 360 days in the case of all Borrowings (other
than Base Rate Borrowings) (unless the calculation would result in an interest
rate greater than the Maximum Rate, in which event interest will be calculated
on the basis of a year of 365 or 366 days, as the case may be), and 365 or 366
days, as the case may be, in the case of Base Rate Borrowings.

                                       25
<PAGE>
 
All interest rate determinations and calculations by Administrative Agent are
conclusive and binding absent manifest error.

     (b) The provisions of this Agreement relating to calculation of the Base
Rate, the Eurodollar Rate, and the Competitive Bid Rate are included only for
the purpose of determining the rate of interest or other amounts to be paid
under this Agreement that are based upon those rates.  Each Lender may fund and
maintain its funding of all or any part of each Borrowing as it selects.

     3.8 Maximum Rate.  Regardless of any provision contained in any Loan
Document or any document related thereto, it is the intent of the parties to
this Agreement that no Credit Party contract for, charge, take, reserve,
receive, or apply, as interest on all or any part of the Obligation any amount
in excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable Law, and, if Lenders ever do so, then
any excess shall be treated as a partial repayment or prepayment of principal
and any remaining excess shall be refunded to Borrower.  In determining if the
interest paid or payable exceeds the Maximum Rate, Borrower and Lenders shall,
to the maximum extent permitted under applicable Law, (a) treat all Borrowings
as but a single extension of credit (and Lenders and Borrower agree that is the
case and that provision in this Agreement for multiple Borrowings is for
convenience only), (b) characterize any non-principal payment as an expense,
fee, or premium rather than as interest, (c) exclude voluntary repayments or
prepayments and their effects, and (d) amortize, prorate, allocate, and spread
the total amount of interest throughout the entire contemplated term of the
Obligation.  However, if the Obligation is paid in full before the end of its
full contemplated term, and if the interest received for its actual period of
existence exceeds the Maximum Amount, then Lenders shall refund any excess (and
Lenders may not, to the extent permitted by Law, be subject to any penalties
provided by any Laws for contracting for, charging, taking, reserving or
receiving interest in excess of the Maximum Amount).  If the Laws of the State
of Texas are applicable for purposes of determining the "Maximum Rate" or the
"Maximum Amount," then those terms mean the "weekly ceiling" from time to time
in effect under Article 5069-1D.009, Title 79, Revised Civil Statutes of Texas,
as amended.  Borrower agrees that Chapter 346 of the Texas Finance Code, as
amended (which regulates certain revolving credit loan accounts and revolving
tri-party accounts), does not apply to the Obligation.

     3.9 Interest Periods.  When Borrower requests any Eurodollar Borrowing or
a Fixed Rate Borrowing, Borrower may elect the applicable interest period (each
an "Interest Period"), which may be, at Borrower's option, one (1), two (2),
three (3) or six (6) months for Eurodollar Borrowings and any period of up to
six (6) months (for Fixed Rate Borrowings), subject to the following conditions:
(a) the initial Interest Period for a Eurodollar Borrowing commences on the
applicable Borrowing Date or conversion date, and each subsequent Interest
Period applicable to such Borrowing commences on the day when the next preceding
applicable Interest Period expires; (b) if any Interest Period for a Eurodollar
Borrowing begins on a day for which there exists no numerically corresponding
Business Day in the calendar month at the end of the Interest Period ("Ending
Calendar Month"), then the Interest Period ends on the next succeeding Business
Day of the Ending Calendar Month, unless there is no succeeding Business Day in
the Ending Calendar Month in which case the Interest Period ends on the next
preceding Business Day of the Ending Calendar Month; (c) no Interest Period may
extend beyond the Termination Date; and (d) there may not be in effect at any
one time more than twelve (12) Interest Periods (including, without limitation,
Interest Periods for Competitive Borrowings). Notwithstanding the foregoing,
subject to the foregoing conditions and the consent of Administrative Agent
(such consent to be in Administrative Agent's reasonable discretion), Borrower
may, in anticipation of Borrower's prepayment of Borrowings from equity or debt
offerings or financings, elect Interest Periods of seven (7) days, fourteen (14)
days, or twenty-one (21) days.

                                       26
<PAGE>
 
      3.10 Conversions.  Borrower may (a) on the last day of the applicable
Interest Period convert all or part of a Eurodollar Borrowing to a Base Rate
Borrowing, (b) at any time convert all or part of a Base Rate Borrowing to a
Eurodollar Borrowing, and (c) on the last day of an Interest Period, elect a new
Interest Period for a Eurodollar Borrowing; provided that no conversions to or
elections of new Interest Periods for any Eurodollar Borrowings shall be
permitted while a Default exists unless Required Lenders otherwise consent in
writing.  Any such conversion is subject to the dollar limits and denominations
of Section 2.1 and may be accomplished by delivering a Borrowing Request to
Administrative Agent no later than 11:00 a.m. (i) on the third (3rd) Business
Day before (A) the conversion date for conversion to a Eurodollar Borrowing and
(B) the last day of the Interest Period, for the election of a new Interest
Period, and (ii) one (1) Business Day before the last day of the Interest Period
for conversion to a Base Rate Borrowing.  Absent Borrower's notice of conversion
or election of a new Interest Period, a Eurodollar Borrowing shall be converted
to a Base Rate Borrowing when the applicable Interest Period expires.

      3.11 Order of Application.

     (a) If no Default exists, any payment shall be applied to the Obligation in
the order and manner specified by Borrower.

     (b) If a Default exists, any payment (including proceeds from the exercise
of any Rights) shall be applied in the following order:  (i) to all fees and
expenses for which the Credit Parties have not been paid or reimbursed in
accordance with the Loan Documents (and if such payment is less than all unpaid
or unreimbursed fees and expenses, then the payment 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 Principal Debt of any
Swing Line Loans; and (iv) to the remaining Obligation in the order and manner
as Administrative Agent deems appropriate.

All payments to or for the account of Lenders shall be shared by such Lenders on
a Pro Rata basis.

      3.12 Sharing of Payments, Etc.  If any Lender obtains any amount (whether
voluntary, involuntary or otherwise, including as a result of exercising its
Rights under Section 3.13) that exceeds the part of that payment that such
Lender is then entitled to receive under the Loan Documents, then such Lender
shall purchase from the other Lenders participations that will cause the
purchasing Lender to share the excess amount ratably with each other Lender.  If
all or any portion of any excess amount 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 3.12 may, to
the fullest extent permitted by Law, exercise all of its Rights of payment
(including the Right of offset) with respect to that participation as fully as
if such Lender were the direct creditor of Borrower in the amount of that
participation.

      3.13 Offset. If a Default exists, then each Lender is entitled, but is not
obligated, to 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 Borrower 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.

      3.14 Booking Borrowings.  To the extent permitted by Law, any Lender may
make, carry or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office of any of its 

                                       27
<PAGE>
 
Affiliates. However, no Affiliate is entitled to receive any greater payment
under this Agreement than the transferor Lender would have been entitled to
receive with respect to those Borrowings.

      3.15 Basis Unavailable or Inadequate for the Eurodollar Rate.  If prior to
the first (1/st/) day of any Interest Period, (a) Administrative Agent
determines that the basis for determining the applicable rate is not available,
or (b) Lenders holding fifty percent (50%) of the Total Commitment notify
Administrative Agent that such Lenders have determined that the rate determined
by Administrative Agent as the Eurodollar Rate for any Interest Period does not
accurately reflect the cost to such Lenders of making or converting Borrowings
at that rate for such 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 all affected Borrowings shall
bear interest at the sum of the Base Rate plus the Applicable Margin.  Until
Administrative Agent notifies Borrower that such circumstances no longer exist,
Lenders' commitments under this Agreement to make, or to convert to, affected
Borrowings will be suspended.

      3.16 Additional Costs.  With respect to any Law, requirement, request,
directive, or change affecting banking institutions generally:

     (a) Eurocurrency Reserves.  If any Lender shall be required under any
Reserve Requirement (other than a Reserve Requirement in effect on the first
(1/st/) day of the respective Interest Period with respect to any Competitive
Borrowings) to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency Liabilities, then (i) such Lender
(through Administrative Agent) shall, within sixty (60) days after the end of
any Interest Period with respect to any Eurodollar Borrowing during which such
Lender was so required to maintain reserves, deliver to Borrower a certificate
stating (A) that such Lender was required to maintain reserves and as a result
such Lender incurred additional costs in connection with making such Eurodollar
Borrowing and (B) in reasonable detail, such Lender's computations of the amount
of additional interest payable by Borrower, pursuant to the provisions below,
and (ii) Borrower shall, within ten (10) days after receipt of any such
certificate, pay to Administrative Agent, for the account of such Lender,
additional interest on the unpaid principal amount of such Eurodollar Borrowing
of such Lender made to it outstanding during the Interest Period with respect to
which the above-referenced certificate was delivered to Administrative Agent, at
a rate per annum equal to the difference obtained by subtracting (x) the
Eurodollar Rate for such Interest Period from (y) the rate obtained by dividing
such Eurodollar Rate by a percentage equal to 100% minus the Reserve Requirement
of such Lender for such Interest Period.  The amount of interest payable by
Borrower to any Lender as stated in any certificate delivered to Administrative
Agent pursuant to the provisions of this Section 3.16(a) shall be conclusive and
binding for all purposes, absent manifest error. The provisions of this Section
3.16(a) shall survive the termination of this Agreement.

     (b) Reserves.  With respect to any Eurodollar Borrowing or any Fixed Rate
Borrowing, if (i) any change in present Law, any change in the interpretation or
application of any present Law, or any future Law imposes, modifies, or deems
applicable (or if compliance by any Lender with any such requirement of any
Tribunal results in) any requirement that any reserves (including any marginal,
emergency, supplemental or special reserves) be maintained, and (ii) those
reserves reduce any sums receivable by such Lender under this Agreement or
increase the costs incurred by such Lender in advancing or maintaining any
portion of any Eurodollar Borrowing or any Fixed Rate Borrowing, then (unless
the effect is already reflected in the rate of interest then applicable under
this Agreement) such 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 such reduction or increase (which
certificate is conclusive and binding absent manifest error), and Borrower shall
within ten (10) days after receipt of such certificate pay that amount to
Administrative Agent, for the account of such Lender.  Such Lender shall notify
Administrative Agent and 

                                       28
<PAGE>
 
Borrower of any such determination as soon as practicable (but in any event
within 120 days) after such Lender obtains actual knowledge of the event or
condition prompting such Lender to make such determination, and Borrower shall
not be liable for any such amount or amounts that accrue between the date such
notification is required to be given and the date notice was actually given. The
provisions of and undertakings and indemnification set forth in this Section
3.13(b) shall survive the satisfaction and payment of the Obligation and
termination of this Agreement.

     (c) Capital Adequacy.  With respect to any Borrowing, if any change in
present Law or any future Law regarding capital adequacy or compliance by any
Credit Party with any request, directive, or requirement now existing or
hereafter imposed by any Tribunal regarding capital adequacy, or any change in
its written policies or in the risk category of this transaction, 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, use
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) such
Credit Party (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 within ten (10) days after receipt of
such certificate pay that amount to Administrative Agent, for the account of
such Credit Party.  Such Credit Party shall notify Administrative Agent and
Borrower of any such determination as soon as practicable (but in any event
within 120 days) after such Credit Party obtains actual knowledge  of the event
or condition prompting such Lender to make such determination, and Borrower
shall not be liable for any such amount or amounts that accrue between the date
such notification is required to be given and the date notice was actually
given.  The provisions of and undertakings and indemnification set forth in this
Section 3.13(c) shall survive the satisfaction and payment of the Obligation and
termination of this Agreement.

     (d) Taxes.  Any Taxes payable by any Credit Party or ruled (by a Tribunal)
payable by any Credit Party in respect of this Agreement or any other Loan
Document shall, if permitted by Law, be paid by Borrower, together with interest
and penalties, if any (except for (i) (1) Taxes imposed on or measured by the
overall net income of such Credit Party, (2) franchise or similar taxes of such
Credit Party, and (3) amounts requested to be withheld for Taxes pursuant to the
last sentence of Section 3.19, and (ii) such interest and penalties incurred as
a result of the gross negligence or willful misconduct of any Credit Party).
Such Credit Party (through Administrative Agent) shall notify Borrower and
deliver to Borrower a certificate setting forth in reasonable detail the
calculation of the amount of payable Taxes, which certificate is conclusive and
binding (absent manifest error), and Borrower shall within ten (10) days after
receipt of such certificate pay that amount to Administrative Agent for its
account or the account of such Credit Party, as the case may be.  If such Credit
Party 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 Law. If any Law makes it unlawful for any Lender to make or
maintain Eurodollar Borrowings, then such Lender shall promptly notify Borrower
and Administrative Agent, and with respect to such Lender's Borrowings (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,
and Borrower shall pay any related Funding Loss, or (ii) if not prohibited by
Law, the Borrowing shall be converted to a Base Rate Borrowing as of the last
day of the 

                                       29
<PAGE>
 
applicable Interest Period, or (iii) if any conversion will not resolve the
unlawfulness, then Borrower shall promptly prepay the Borrowing, without
penalty, together with any related Funding Loss.

      3.18 Funding Loss.  BORROWER AGREES TO INDEMNIFY EACH LENDER AGAINST, AND
PAY TO EACH LENDER WITHIN TEN (10) DAYS AFTER DEMAND, ANY FUNDING LOSS OF SUCH
LENDER. When any Lender demands that Borrower pay any Funding Loss, such Lender
shall deliver to Borrower and Administrative Agent a certificate setting forth
in reasonable detail the basis for such Funding Loss and the calculation of the
amount, which calculation is conclusive and binding absent manifest error.  The
provisions of and undertakings and indemnification set forth in this Section
3.18 shall survive the satisfaction and payment of the Obligation and
termination of this Agreement.

      3.19 Foreign Lenders.  Each Lender that is organized under the Laws of any
jurisdiction other than the United States of America or any State thereof (a)
represents to Administrative Agent and Borrower that (i) no Taxes are required
to be withheld by Administrative Agent or Borrower with respect to any payments
to be made to it in respect of the Obligation, and (ii) it has furnished to
Administrative Agent and Borrower two duly completed copies of U.S. Internal
Revenue Service Form 4224, Form 1001, Form W-8, or any other tax form acceptable
to Administrative Agent (wherein it claims entitlement to complete exemption
from U.S. federal withholding tax on all interest payments under the Loan
Documents), and (b) covenants to (i) provide Administrative Agent and Borrower a
new tax form upon the expiration or obsolescence of any previously delivered
form according to Law, duly executed and completed by it, and (ii) comply from
time to time with all Laws with regard to the withholding tax exemption.  If any
of the foregoing is not true or the applicable forms are not provided, then
Borrower or Administrative Agent (without duplication) may deduct and withhold
from interest payments under the Loan Documents United States federal income tax
at the full rate applicable under the Code.

      3.20 Extension of Termination Date.  Borrower may request a one-year
extension of the then-existing Termination Date by making such request in
writing (an "Extension Request") to Administrative Agent between sixty (60) and
ninety (90) days prior to March 29, 2001.  The Termination Date shall be
extended to March 29, 2002 only if (a) Borrower pays to Administrative Agent the
extension fee set forth in Section 4.4, and (b) no Default or Potential Default
exists at the time of Borrower's request for such extension.

      3.21 Option to Replace Lenders.  If any Lender shall make demand for
payment or reimbursement pursuant to Section 3.16, or notify Borrower of the
occurrence of the circumstances described in Section 3.17, then, provided that
(a) no Default has occurred and is continuing, and (b) the circumstances
resulting in such demand for payment or reimbursement are not applicable to all
Lenders, Borrower may terminate the Commitment of such Lender, in whole but not
in part, by either (i) (A) giving such Lender and Administrative Agent not less
than five (5) Business Days' written notice thereof, which notice shall be
irrevocable and effective only upon receipt thereof by such Lender and
Administrative Agent and shall specify the date of such termination, and (B)
paying such Lender (and there shall become due and payable) on such date the
outstanding Principal Debt of all Borrowings made by such Lender, all interest
thereon, and any other Obligation owed to such Lender (including under Section
3.18), if any, and/or (ii) pursuant to the provisions of Section 13.11,
proposing the introduction of a replacement Lender reasonably satisfactory to
Administrative Agent, or obtaining the agreement of one or more existing
Lenders, to assume all or a portion of the Commitment of the Lender whose
Commitment is being terminated, on the effective date of such termination.  Upon
the satisfaction of all of the foregoing conditions, such Lender that is being
terminated shall cease to be a "Lender" for purposes of this Agreement, provided
that Borrower shall continue to be 

                                       30
<PAGE>
 
obligated to such Lender under Section 7.12 with respect to Indemnified
Liabilities (as defined in Section 7.12) arising prior to such termination.

SECTION 4 FEES.
- --------- ---- 

      4.1 Treatment of Fees.  The fees described in this Section 4 (a) are not
compensation for the use, detention, or forbearance of money, (b) are in
addition to, and not in lieu of, interest and expenses otherwise described in
this Agreement, (c) are payable in accordance with Section 3.1(b), (d) are non-
refundable, (e) to the fullest extent permitted by Law, bear interest, if not
paid when due, at the Default Rate, and (f) are 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 360 days, unless
computation would result in an interest rate in excess of the Maximum Rate in
which event the computation is made on the basis of a year of 365 or 366 days,
as the case may be.  The fees described in this Section 4 are in all events
subject to the provisions of Section 3.8.

      4.2 Administrative Agent Fees.  Borrower shall pay to Administrative
Agent, solely for its own account, the fees described in the letter agreement
between Borrower and Administrative Agent dated of even date herewith.

      4.3 Commitment Fees.

     (a) Borrower shall pay to Administrative Agent the fees specified in the
Letter Agreement between Administrative Agent and Borrower, which fee shall be
for the account of Administrative Agent and for the account of Lenders as shall
be agreed to between Administrative Agent and each Lender.

     (b) Borrower shall pay to Administrative Agent, for the ratable account of
each Lender, a facility fee equal to the product of (i) the average daily amount
of the Total Commitment (regardless of usage) for the period from and including
the Closing Date up to but excluding the Termination Date, times (ii) a rate per
annum equal to the Applicable Facility Fee Percentage.  Such facility fee shall
be payable quarterly in arrears on the first (1/st/) day of each January, April,
July, and October during the term hereof, commencing on July 1, 1999.

      4.4 Extension Fee.  Upon the extension of the Termination Date, as
provided in Section 3.20, Borrower agrees to pay Administrative Agent, on or
before March 29, 2001, for the ratable account of Lenders, an extension fee
equal to one-quarter of one percent (.25%) of the Commitments of Lenders.

      4.5 Competitive Bid Fee.  Each Competitive Bid Request hereunder submitted
by Borrower to Administrative Agent shall be accompanied by a competitive bid
fee of $2,500 (payable solely to Administrative Agent for its own account) and
shall only request bids for a single Borrowing Date.

 SECTION 5  CONDITIONS PRECEDENT.  Administrative Agent will not be obligated to
- ----------  --------------------                                                
fund the initial Borrowing unless: (a) Administrative Agent has timely received
a Borrowing Request and all of the items described on Schedule 5; and (b) prior
to, or contemporaneously with, such initial Borrowing, all Indebtedness under
the Existing Credit Agreement is paid in full and all commitments thereunder are
terminated.  In addition, Administrative Agent will not be obligated to make any
Borrowing (including any Competitive Borrowing), unless on the applicable
Borrowing Date (and after giving effect to the requested Borrowing): (i)
Administrative Agent shall have timely received a Borrowing Request or
Competitive Bid Request, as the case may be; (ii) Administrative Agent shall
have received any applicable fees; (iii) all of 

                                       31
<PAGE>
 
the representations and warranties of Borrower in the Loan Documents are true
and correct in all material respects (unless they speak to a specific date or
are based on facts which have changed by transactions contemplated or permitted
by this Agreement); (iv) no Default or Potential Default exists; and (v) the
funding of the Borrowing is permitted by Law. Upon Administrative Agent's
request, Borrower shall deliver to Administrative Agent evidence substantiating
any of the matters in the Loan Documents that are necessary to enable Borrower
to qualify for the Borrowing. Each condition precedent in this Agreement
(including those on Schedule 5) is material to the transactions contemplated by
this Agreement, and time is of the essence with respect to each condition
precedent. Lenders may fund any Borrowing without all conditions being
satisfied, but, to the extent permitted by Law, that funding and issuance shall
not be deemed to be a waiver of the requirement that each condition precedent be
satisfied as a prerequisite for any subsequent funding or issuance, unless
Lenders specifically waive each item in writing.

SECTION 6 REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants to
- --------- ------------------------------                                      
the Credit Parties as follows:

      6.1 Purpose of Credit Facility.  Borrower will use proceeds of the
Borrowings hereunder for working capital and general business purposes of the
Companies and their Unconsolidated Affiliates.  Borrower is not engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System,
as amended.  No part of the proceeds of any Borrowing will be used, directly or
indirectly, for a purpose that violates any Law, including the provisions of
Regulation U.

      6.2 Corporate Existence, Good Standing, Authority and Compliance.  Each
Company is duly formed, validly existing, and in good standing under the Laws of
the jurisdiction in which it is incorporated or formed as identified on Schedule
6.2 (as supplemented from time to time).  Each Company (a) is duly qualified to
transact business and is in good standing as a foreign trust, corporation,
partnership, limited liability company, or other entity in each jurisdiction
where the nature and extent of its business and properties require due
qualification and good standing, (b) possesses all requisite authority, permits,
and power to conduct its business as is now being, or is contemplated by this
Agreement to be, conducted, and (c) is in compliance with all applicable Laws,
except in any such case where violation of the foregoing could not reasonably be
expected to result in a Material Adverse Event.

      6.3 Affiliates.  As of the date of this Agreement, Borrower has no
Consolidated Affiliates or Unconsolidated Affiliates except as disclosed on
Schedule 6.2 (as supplemented from time to time to reflect changes as a result
of transactions permitted by this Agreement).

      6.4 Authorization and Contravention.  The execution and delivery by
Borrower of each Loan Document or related document to which it is a party and
the performance by it of its obligations thereunder (a) are within its trust
power, (b) have been duly authorized by all necessary trust action, (c) require
no action by or filing with any Tribunal (other than any action or filing that
has been taken or made on or before the date of this Agreement), (d) do not
violate any provision of its declaration of trust or bylaws, (e) do not violate
any provision of Law or order of any Tribunal applicable to it, (f) do not
violate any material agreements to which it is a party, or (g) do not result in
the creation or imposition of any Lien on any asset of any Company, except in
such case where failure to do so could not reasonably be expected to result in a
Material Adverse Event.

                                       32
<PAGE>
 
      6.5 Binding Effect.  Upon execution and delivery by all parties thereto,
each Loan Document to which it is a party will constitute a legal and binding
obligation of Borrower, enforceable against it in accordance with its terms,
subject to applicable Debtor Relief Laws and general principles of equity.

      6.6 Financial Statements; Fiscal Year.  The Current Financials were
prepared in accordance with GAAP (except that quarterly Financial Statements may
omit footnotes required by GAAP) and present fairly, in all material respects,
the consolidated financial condition, results of operations, and cash flows of
the Companies as of, and for the portion of the fiscal year ending on, the date
or dates thereof (subject only to normal audit adjustments).  All material
liabilities of the Companies as of the date or dates of the Current Financials
are reflected therein or in the notes thereto.  Except for transactions directly
related to, or specifically contemplated by, the Loan Documents or disclosed in
the Current Financials, no subsequent material adverse changes have occurred in
the consolidated financial condition of the Companies from that shown in the
Current Financials, nor has any Company incurred any subsequent material
liability.  The fiscal year of the Companies ends on December 31.

      6.7 Litigation.  Except as disclosed on Schedule 6.7 and as otherwise
disclosed pursuant to Section 7.1(d)(i), no Company is subject to, or aware of
the threat of, any Litigation that is reasonably likely to be determined
adversely to such Company and which, if so adversely determined, is reasonably
likely to result in a Material Adverse Event.  Except as permitted under Section
10.4, no outstanding and unpaid judgments against any Company exist.

      6.8 Taxes.

     (a) All Tax returns of the Companies required to be filed have been filed
(or extensions have been granted) before delinquency, except for returns for
which the failure to file could not reasonably be expected to result in a
Material Adverse Event, and all Taxes imposed upon the Companies that are due
and payable have been paid before delinquency or are being contested in good
faith by appropriate proceedings diligently conducted and for which reserves in
accordance with GAAP or otherwise reasonably acceptable to Administrative Agent
have been provided.

     (b) As of the date hereof, no United States federal income tax returns of
the "affiliated group" (as defined in the Code) of which Borrower is a member
have been examined and closed.  The members of such affiliated group have filed
all United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by or any of them.  The
charges, accruals and reserves on the books of Borrower in respect of taxes or
other governmental charges are, in the opinion of Borrower, adequate.

     (c)  Borrower qualifies as a REIT.

      6.9 Environmental Matters.  Except as disclosed on Schedule 6.9, and
except for any of the following which could not reasonably be expected to result
in a Material Adverse Event, (a) no environmental condition or circumstance
exists that adversely affects any Company's properties or operations, (b) no
Company has received any report of any Company's violation of any Environmental
Law, (c) no Company knows that any Company is under any obligation to remedy any
violation of any Environmental Law, or (d) no facility of any Company is used
for, or to the knowledge of any Company has been used for, storage, treatment,
or disposal of any Hazardous Substance,  except for (i) the storage and use of
cleaning and maintenance materials, used and stored in commercially reasonable
quantities and in compliance with applicable Environmental Laws, and (ii) light
manufacturing and distribution activities of 

                                       33
<PAGE>
 
tenants, in compliance with applicable Environmental Laws, provided that such
tenants are not primarily engaged in the treatment, processing, recycling or
disposal of any Hazardous Substance or in any other activity that would give
rise to the release of any Hazardous Substance on such facility. Each Company
has taken prudent steps to determine that its properties and operations do not
violate any Environmental Law, other than violations that, individually or in
the aggregate, could not reasonably be expected to result in a Material Adverse
Event.

      6.10 Pension Plans.  Except as disclosed on the Financial Statements of
Borrower dated as of December 31, 1998, and except to the extent that any such
termination, liability, penalty, or fine would not (either individually or in
the aggregate) reasonably be expected to have a Material Adverse Event, (a) no
steps have been taken to terminate any Pension Plan, and no contribution failure
has occurred with respect to any Pension Plan sufficient to give rise to a Lien
under any Applicable Pension Laws, (b) no condition exists or event or
transaction has occurred with respect to any Pension Plan which could reasonably
be expected to result in the incurrence by Borrower or any ERISA Affiliate of
any material liability with respect to any contribution thereto, fine, or
penalty, and (c) neither Borrower nor any ERISA Affiliate has any material
contingent liability with respect to any post-retirement benefit under a Pension
Plan.

      6.11 Properties; Liens.  Each Company has good title to all its property
reflected on the Current Financials (except for property that is obsolete or
that has been disposed in the ordinary course of business or, after the date of
this Agreement, as otherwise permitted by Section 8.8 or Section 8.9).  Except
for Permitted Liens and Liens on Properties acquired by a Company, provided that
such Liens are not incurred in contemplation of any Company's acquisition of
such Properties, no Lien exists on any Property of any Company in the Pool, and
the execution, delivery, performance, or observance of the Loan Documents will
not require or result in the creation of any Lien on any of any Company's
Property in the Pool.

      6.12 Locations.  Borrower's chief executive office is located at the
address on Schedule 6.12 (as supplemented from time to time).  Borrower's books
and records are located at its chief executive office.

      6.13 Government Regulations. No Company is subject to regulation under the
Investment Company Act of 1940, as amended, or the Public Utility Holding
Company Act of 1935, as amended.

      6.14 Transactions with Affiliates.  Except as disclosed on Schedule 6.14
(as supplemented from time to time) (if the disclosures are approved by
Administrative Agent) or as permitted by Section 8.4, no Company is a party to a
material transaction with any of its Affiliates, other than transactions 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.

      6.15 Insurance.  Each Company maintains 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 operates) insurance
concerning its properties and businesses against casualties and contingencies
and of types and in amounts (and with co-insurance and deductibles) as is
customary in the case of similar businesses.

      6.16 Labor Matters.  No actual or, to Borrower's knowledge, threatened
strikes, labor disputes, slow downs, walkouts, or other concerted interruptions
of operations by the employees of any Company that could reasonably be expected
to result in a Material Adverse Event exist.  All payments due from each Company
for employee health and welfare insurance have been paid or accrued as a
liability on its books, 

                                       34
<PAGE>
 
other than non-payments that are not, individually or collectively, reasonably
expected to result in a Material Adverse Event.

      6.17 Solvency.  On each Borrowing Date, Borrower is, and after giving
effect to the requested Borrowing will be, Solvent.

      6.18 Full Disclosure.  Each material fact or condition relating to the
financial condition or business of any Company which could reasonably be
expected to result in a Material Adverse Event has been disclosed to
Administrative Agent.  All information previously furnished, furnished on the
date of this Agreement, and furnished in the future, by any Company to
Administrative Agent in connection with the Loan Documents (a) was, is, and will
be, true and accurate in all material respects or based on good faith estimates
on the date the information is stated or certified, and (b) did not, does not,
and will not, fail to state any material fact the omission of which would
otherwise make any such information materially misleading, in each case taken as
a whole.

      6.19 Exemption from ERISA; Plan Assets.  The assets of Borrower are not
"plan assets" as defined in 29 C.F.R. (S) 2510.3-101(a)(1) (or any successor
regulation) of any Pension Plan.

      6.20 Minority Interests.  All Consolidated Affiliates of Borrower having
minority interests are set forth on Schedule 6.20 (as supplemented from time to
time).

      6.21 Year 2000 Compliance.  Borrower has (a) initiated a review and
assessment of all areas within each Company's business and operations (including
those affected by suppliers and vendors) that could be adversely affected by the
"Year 2000 Problem" (that is, the risk that computer applications used by any
Company (or its material suppliers and vendors) may be unable to recognize and
perform properly date-sensitive functions involving certain dates prior to and
any date after December 31, 1999), (b) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, and (c) to date, implemented
that plan in accordance with that timetable.  Borrower reasonably believes that
all computer applications (including those of its material suppliers and
vendors) that are material to each Company's business and operations will on a
timely basis be able to perform properly date-sensitive functions for all dates
before and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
the extent that a failure to do so could not reasonably be expected to result in
a Material Adverse Event.

after the date of determination) outstanding on such date (including Unsecured
Debt of Unconsolidated Affiliates to the extent that the holder of such
Indebtedness has recourse against any Company for the payment of such
Indebtedness, except to the extent of any security therefor or pursuant to any
Customary Recourse Exceptions).

Properties and International Properties owned by Borrower or a Pool Consolidated
Affiliate free and clear of any Liens (except Permitted Liens) (the "Operating
Sub-Pool"): (i) with an Implied Value of at least one hundred fifty percent
(150%) of the Companies' Unsecured Debt (less any unrestricted cash and Cash
Equivalents to the extent that such cash and Cash Equivalents are used to pay
such Unsecured Debt within seven (7) days after the date of determination)
outstanding from time to time (including Unsecured Debt of Unconsolidated

<PAGE>
 
occupancy level is the average of the occupancy level for each of the
immediately preceding three (3) months; and (iii) for which Borrower and its
Pool Consolidated Affiliates must have received from third-party independent
environmental consultants, written assessments for each Property in, or to be
added to, the Operating Sub-Pool that do not disclose any material environmental
conditions or risks related to such Properties. Notwithstanding the foregoing,
the Operating Sub-Pool shall not, as of any date, include Refrigerated Warehouse
Properties and International Properties having an Implied Value exceeding in the
aggregate ten percent (10%) of the Implied Value of all Properties in the
Operating Sub-Pool as of such date.

     (c) For purposes of calculating the Historical Value or the Implied Value,

Consolidated Affiliates to execute a Subsidiary Guaranty, except to the extent
that the execution of a Subsidiary Guaranty would result in material adverse tax
Liabilities to Borrower in the United States.

     (b) Pursuant to the Pledge Agreements, (i) Borrower shall, and shall cause
each of its Consolidated Affiliates to, grant to Administrative Agent, for the
benefit of the Credit Parties, a first-priority Lien in all Indebtedness of each

$5,000,000, including, without limitation, the existing Indebtedness listed on
Schedule 7.16-2, and (ii) Borrower shall grant to Administrative Agent, for the
benefit of the Credit Parties, a first-priority Lien in all Indebtedness of

additional Liens (including any mortgages or deeds of trust) in such Properties
for the benefit of the Credit Parties).

material transaction with any of its Affiliates, other than (a) transactions

material respect when made.

      10.7 Default Under Other Agreements.

     (a) Any Company shall fail to make any payment in respect of any Liability

SECTION 11     RIGHTS AND REMEDIES.
- ----------     ------------------- 

      11.1 Remedies Upon Default.

     (a)   If a Default (i) occurs under Section 10.3(c) or (ii) occurs and is
continuing under Section 10.3(a), (b) or (d), the commitment to extend credit
under this Agreement automatically terminates and the entire unpaid balance of
the Obligation automatically becomes due and payable without any action of any
kind whatsoever.

     (b)   If a Default occurs and is continuing, subject to the terms of
Section 12.3(b) and Section 12.10, Administrative Agent may, and upon the
request of Required Lenders shall, 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 balance of all or any part of the Obligation
immediately due and 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) to the extent permitted by Law, exercise (or request
each Lender to, and each Lender is entitled to, exercise) the Rights of offset
or banker's Lien against the interest of each Company in and to every account
and other property of such Company that are in the possession of any Credit
Party to the extent of the full amount of the Obligation (and to the extent
permitted by Law, each Company is deemed directly obligated to each Credit Party
in the full amount of the Obligation for this purpose); and (v) exercise any and
all other legal or equitable Rights afforded by the Loan Documents, the Laws of
the State of Texas, or any other applicable jurisdiction.

      11.2 Waivers.  To the extent permitted by Law, Borrower waives presentment
and demand for payment, protest, notice of intention to accelerate, notice of
acceleration, and notice of protest and nonpayment, 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, or by any release or change in any security for
the payment of all or any part of the Obligation.

                                       46
<PAGE>
 
      11.3 Performance by Administrative Agent.  If any covenant, duty, or
agreement of any Company is not performed in accordance with the terms of the
Loan Documents, then Administrative Agent may, while a Default exists, at its
option, perform or attempt to perform that covenant, duty or agreement on behalf
of such Company (and any amount expended by Administrative Agent in its
performance or attempted performance is payable by Borrower to Administrative
Agent on demand, becomes part of the Obligation, and bears interest at the
Default Rate from the date of Administrative Agent's expenditure until paid).
However, no Credit Party assumes or shall have, except by its express written
consent, any liability or responsibility for the performance of any covenant,
duty, or agreement of any Company.

      11.4 Not in Control.  None of the covenants or other provisions contained
in any Loan Document shall, or shall be deemed to, give any Credit Party the
Right to exercise control over the assets (including real property), affairs, or
management of any Company; the power of each Credit Party is limited to the
Right to exercise the remedies provided in this Section 11.

      11.5 Course of Dealing.  The acceptance by any Credit Party of any partial
payment on the Obligation shall not be deemed to be a waiver of any Default then
existing.  No waiver by any Credit Party of any Default shall be deemed to be a
waiver of any other then-existing or subsequent Default.  No delay or omission
by any Credit Party in exercising any Right under the Loan Documents will impair
that Right or be construed as 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 Loan Documents or
otherwise.

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

      11.7 Application of Proceeds.  Any and all proceeds ever received by any
Credit Party from the exercise of any Rights pertaining to the Obligation shall
be applied to the Obligation according to Section 3.11.

      11.8 Diminution in Value of Collateral.  No Credit Party has any liability
or responsibility whatsoever for any diminution in or loss of value of any
collateral now or hereafter securing payment or performance of all or any part
of the Obligation (other than diminution in or loss of value caused by its gross
negligence or willful misconduct).

      11.9 Certain Proceedings.  Borrower will promptly execute and deliver, or
cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers any
Credit Party reasonably requests in connection with the obtaining of any
consent, approval, registration, qualification, permit, license, or
authorization of any Tribunal or other Person necessary or appropriate for the
effective exercise of any Rights under the Loan Documents.  Because Borrower
agrees that the Credit Parties' remedies at Law for failure of Borrower to
comply with the provisions of this paragraph would be inadequate and that
failure would not be adequately compensable in damages, Borrower agrees that the
covenants of this Section 11.9 may be specifically enforced.

SECTION 12  AGENTS AND LENDERS.
- ----------  ------------------ 

      12.1 Agents.

     (a) Appointment.  Each Lender appoints Administrative Agent (and
Administrative Agent accepts appointment) as its nominee and agent, in its name
and on its behalf:  (i) to act as its nominee and on its behalf in and under all
Loan Documents; (ii) to arrange the means whereby its funds are to be made
available to Borrower under the Loan Documents; (iii) to take any action that it
properly requests under the Loan Documents (subject to the concurrence of other
Lenders as may be required under the Loan Documents); (iv) to receive all
documents and items to be furnished to it under the Loan Documents; (v) to be
the secured party, mortgagee, beneficiary, recipient, and similar party in
respect of any collateral, if any, for the benefit of Lenders; (vi) to promptly
distribute to it all Financial Statements, notices received hereunder, and other
items specifically required to be delivered to it hereunder and, upon request,
such other material information, requests, documents, and items received from
Borrower under the Loan Documents; (vii) 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 Loan Documents; (viii) to deliver
to the appropriate Persons requests, demands, approvals, and consents received
from it; and (ix) to arrange for inspections pursuant to Section 7.4.  However,
Administrative Agent may not be required to take any action that exposes it to
personal liability or that is contrary to any Loan Document or applicable Law.

     (b) Successor.  Administrative Agent may assign all of its Rights and
obligations as Administrative Agent under the Loan Documents to any of its
Affiliates, which Affiliate shall then be the successor Administrative Agent
under the Loan Documents.  Administrative Agent may also voluntarily resign by
giving thirty (30) days' prior written notice to Borrower and Lenders, and shall
resign upon the request of the Required Lenders for cause (i.e., Administrative
Agent is continuing to fail to perform its responsibilities as Administrative
Agent under the Loan 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 the Required Lenders), then the Required Lenders shall (which, if no
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 the Required
Lenders fail to appoint a successor Administrative Agent within thirty (30) days
after the resigning Administrative Agent has given notice of resignation or the
Required Lenders have removed the resigning Administrative Agent, then the
resigning Administrative Agent may, on behalf of Lenders, appoint a successor
Administrative Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of condition)
and whose debt obligations (or whose parent's debt obligations) are rated not
less than Baa1 by Moody's or BBB+ by S & P.  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
as Administrative Agent under the Loan Documents, and each Lender shall execute
the documents that any Lender, the resigning or removed Administrative Agent, or
the successor Administrative Agent reasonably requests to reflect the change.
After any Administrative Agent's resignation or removal as Administrative Agent
under the Loan 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 Loan Documents.  If Borrower fails to respond to any written request for any
consent required in this 

                                       48
<PAGE>
 
Section 12.1(b) within ten (10) days after the date that Borrower receives such
request, then Borrower shall be deemed to have given its consent to such
request.

     (c) Syndication Agent.   Syndication Agent, in such capacity, shall have no
rights, duties, or obligations hereunder, except as specifically provided in
this Agreement.  Syndication Agent (i) may voluntarily resign by notice to
Administrative Agent, Lenders, and Borrower, and (ii) shall resign upon the
request of the Required Lenders for cause.  Upon the resignation of Syndication
Agent, Administrative Agent may elect to designate a successor Syndication Agent
(which, if no Default or Potential Default exists, is subject to Borrower's
approval that may not be unreasonably withheld), which must be a Lender who is a
commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of condition)
and whose debt obligations (or whose parent's debt obligations) are rated not
less than Baa1 by Moody's or BBB+ by S & P.

     (d) Documentation Agent.   Documentation Agent, in such capacity, shall
have no rights, duties, or obligations hereunder, except as specifically
provided in this Agreement.  Documentation Agent (i) may voluntarily resign by
notice to Administrative Agent, Lenders, and Borrower, and (ii) shall resign
upon the request of the Required Lenders for cause.  Upon the resignation of
Documentation Agent, Administrative Agent may elect to designate a successor
Documentation Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a Lender who is a commercial bank having a combined capital and surplus
of at least $10,000,000,000 (as shown on its most recently published statement
of condition) and whose debt obligations (or whose parent's debt obligations)
are rated not less than Baa1 by Moody's or BBB+ by S & P.

      12.2 Delegation of Duties; Reliance.  Lenders may perform any of their
duties or exercise any of their Rights under the Loan 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 Loan Documents by or
through their respective Representatives.  The Credit Parties 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 any 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 any other Loan Document or (ii) any other writing if a
specific writing is required by this Agreement or any other Loan Document), (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 such Lender's
portion of the Obligation until that notice is given and received), (c) are not
deemed to have notice of the occurrence of a Default unless a responsible
officer of Administrative Agent, who handles matters associated with the Loan
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.

      12.3 Limitation of Administrative Agent's Liability.

     (a)     Exculpation.  Neither Administrative Agent nor any of its
representatives will be liable for any action taken or omitted to be taken by it
or them under the Loan Documents in good faith and believed 

                                       49
<PAGE>
 
by it or them to be within the discretion or power conferred upon it or them by
the Loan 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 Representatives has a fiduciary
relationship with any Lender by virtue of the Loan 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 Loan 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 Loan Documents. If Administrative Agent requests instructions
from Lenders, with respect to any act or action in connection with any Loan
Document, then 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 such Lender, (ii) the effectiveness,
enforceability, genuineness, validity, or due execution of any Loan 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 Loan Document, or (v) observation of or compliance with
any of the terms, covenants, or conditions of any Loan 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 PRO RATA PART 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 LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE LOAN
DOCUMENTS IF ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR
SUCH AMOUNTS BY BORROWER.  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.

      12.4 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.

      12.5 Expenses.  Should Administrative Agent commence any proceeding or in
any way seek to enforce its Rights under the Loan Documents, each Lender, upon
demand therefor from time to time, shall contribute its share (based on its Pro
Rata Part) of the reasonable costs and/or expenses of any such 

                                       50
<PAGE>
 
enforcement, including, but not limited to, fees of receivers or trustees, court
costs, title company charges, filing and recording fees, appraisers' fees and
fees and expenses of attorneys to the extent not otherwise reimbursed by
Borrower. Without limiting the generality of the foregoing, each Lender shall
contribute its share (based on its Pro Rata Part) of all reasonable costs and
expenses incurred by Administrative Agent (including reasonable attorneys' fees
and expenses) if Administrative Agent employs counsel for advice or other
representation (whether or not any suit has been or shall be filed) with respect
to any of the Loan Documents, or to enforce any rights of Administrative Agent
or any of Borrower's or any other Company's obligations under any of the Loan
Documents, but not with respect to any dispute between Administrative Agent and
any other Lender(s). Any loss of principal and interest resulting from any
Default shall be shared by Lenders in accordance with their respective Pro Rata
Parts. It is understood and agreed that if Administrative Agent determines that
it is necessary to engage counsel for Lenders from and after the occurrence of a
Potential Default or Default, then said counsel shall be selected by
Administrative Agent and written notice of the same shall be delivered to
Lenders.

      12.6 Proportionate Absorption of Losses.  Except as otherwise provided in
the Loan Documents, nothing in the Loan 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 obligor on the Obligation having any credit,
allowance, setoff, defense, or counterclaim solely with respect to all or any
part of such Lender's Pro Rata Part of the Obligation).

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

      12.8 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 nor any other Person is responsible or
liable for, entitled to rely upon, or entitled to raise as a defense -- in any
manner whatsoever -- the failure of any Credit Party to comply with these
provisions.

      12.9 Approval of Lenders.

     (a) All communications from Administrative Agent to any Lender requesting
such Lender's determination, consent, approval, or disapproval (i) shall be
given in the form of a written notice to each Lender, (ii) shall be accompanied
by a description of the matter or thing as to which such determination,
approval, consent, or disapproval is requested, or shall advise each Lender
where such matter or thing may be inspected, or shall otherwise describe the
matter or issue to be resolved, (iii) shall include, if reasonably requested by
a Lender and to the extent not previously provided to such Lender, written
materials and a summary of all oral information provided to Administrative Agent
by Borrower in respect of the matter or issue to be resolved, and (iv) shall
include Administrative Agent's recommended course of action or determination in
respect thereof.  Each Lender shall reply promptly, but in any event (x) within
thirty (30) days (or such lesser period as may be required under the Loan
Documents for Administrative Agent to respond) for those matters requiring the
consent by all Lenders, and (y) within fifteen (15) Business Days (or such
lesser period as may be required under the Loan Documents for Administrative
Agent to respond) for those matters requiring the consent by the Required
Lenders, in each instance, after receipt of the request therefor by
Administrative Agent (in either event, the "Lender Reply Period").

     (b) Unless a Lender shall give written notice to Administrative Agent that
it objects to the recommendation or determination of Administrative Agent
(together with a written explanation of the 

                                       51
<PAGE>
 
reasons behind such objection) within the Lender Reply Period, such Lender shall
be deemed to have approved of or consented to such recommendation or
determination.

      12.10 Default; Collateral.  Upon the occurrence and during the continuance
of a Default, the Credit Parties 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 the Credit Parties; and Administrative Agent
shall be entitled to refrain from taking any action (without incurring any
liability to any Person for so refraining) unless and until Administrative Agent
shall have received instructions from Required Lenders or Lenders, as the case
may be.  All rights of action under this Agreement and under the Notes and all
rights to any collateral, if any, hereunder may be enforced by Administrative
Agent and any suit or proceeding instituted by Administrative Agent in
furtherance of such enforcement shall be brought in its respective name as
Administrative Agent without the necessity of joining as plaintiffs or
defendants any other Credit Party, and the recovery of any judgment shall be for
the benefit of the Credit Parties subject to the expenses of Administrative
Agent.  In actions with respect to any property of any Company, Administrative
Agent is acting for the ratable benefit of each Credit Party.

SECTION 13   MISCELLANEOUS.
- -----------  ------------- 

      13.1 Headings. The headings, captions, and arrangements used in any of the
Loan Documents are, unless specified otherwise, for convenience only and shall
not be deemed to limit, amplify, or modify the terms of the Loan Documents, nor
affect the meaning thereof.

      13.2 Nonbusiness Days; Time.  Any payment or action that is due under any
Loan 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 Eurodollar
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.

      13.3 Communications.  Unless otherwise specifically provided, whenever any
Loan Document requires or permits any consent, approval, notice, request,
demand, or other communication from one party to another, communication must be
in writing (which may be by telex or telecopy) to be effective and shall be
deemed to have been given (a) if by telex, when transmitted to the appropriate
telex number and the appropriate answerback is received, (b) if by telecopy,
when transmitted to the appropriate telecopy number (and all communications sent
by telecopy must be confirmed promptly thereafter by telephone; but any
requirement in this parenthetical shall not affect the date when the telecopy
shall be deemed to have been delivered), (c) if by mail, on the fifth (5th)
Business Day after it is enclosed in an envelope and properly addressed,
stamped, sealed, certified mail, return receipt requested, and deposited in the
appropriate official postal service, or (d) if by any other means, when actually
delivered.  Until changed by notice pursuant to this Agreement, the address (and
telecopy number) for each party to this Agreement is set forth on Schedule 1.

      13.4 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.

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

                                       52
<PAGE>
 
      13.6 Governing Law.  EXCEPT AS EXPRESSLY PROVIDED IN A LOAN DOCUMENT, THE
LAWS (OTHER THAN CONFLICT-OF-LAWS PROVISIONS) OF THE STATE OF TEXAS AND OF THE
UNITED STATES OF AMERICA GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN
DOCUMENTS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE
LOAN DOCUMENTS.

      13.7 Invalid Provisions.  Any provision in any Loan Document held to be
illegal, invalid or unenforceable is fully severable; the appropriate Loan
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.  The Credit Parties and Borrower
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.  However, if the provision held to be illegal, invalid or
unenforceable is a material part of this Agreement, such invalid, illegal or
unenforceable provision shall be, to the extent permitted by Law, replaced by a
clause or provision judicially construed and interpreted to be as similar in
substance and content to the original terms of such illegal, invalid or
unenforceable clause or provision as the context thereof would reasonably allow,
so that such clause or provision would thereafter be legal, valid and
enforceable.

      13.8 Venue; Service of Process; Jury Trial.  EACH PARTY TO ANY LOAN
DOCUMENT, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE CASE
OF BORROWER, FOR EACH OF THE OTHER COMPANIES), (a) IRREVOCABLY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS OF THE STATE OF TEXAS,
(b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY LITIGATION
ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE OBLIGATION
BROUGHT IN DISTRICT COURTS OF DALLAS OR HARRIS COUNTY, TEXAS, OR IN THE UNITED
STATES DISTRICT COURT FOR THE NORTHERN OR SOUTHERN DISTRICT OF TEXAS, DALLAS OR
HOUSTON DIVISION, (c) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT
IN ANY OF THE AFOREMENTIONED COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM,
(d) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THOSE COURTS IN
ANY LITIGATION BY THE MAILING OF COPIES THEREOF 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 SET FORTH IN THIS AGREEMENT, (e)
IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY LOAN
DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR THE
OBLIGATION MAY BE BROUGHT IN ONE OF THE AFOREMENTIONED COURTS, AND (f)
IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, ITS RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY
LOAN DOCUMENT.  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 contract claims,
tort claims, breach of duty claims, and all other common law and statutory
claims.  Borrower (for itself and on behalf of each of the other Companies)
acknowledges that these waivers are a material inducement to each Credit Party's
agreement to enter into a business relationship, that each Credit Party has
already relied on these waivers in entering into this Agreement, and that each
Agent and each Lender will continue to rely on each of these waivers in related
future dealings.  Borrower (for itself and on behalf of each other Company)
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 

                                       53
<PAGE>
 
SECTION 13.8 ARE IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN
DOCUMENT. In the event of Litigation, this Agreement may be filed as a written
consent to a trial by the court.

      13.9 Amendments, Consents, Conflicts, and Waivers.

     (a) Required Lenders.  Unless otherwise specifically provided the
provisions of this Agreement may be amended, modified, or waived only by an
instrument in writing executed by Borrower and the Required Lenders and
supplemented only by documents delivered or to be delivered in accordance with
the express terms of this Agreement.

     (b) All Lenders.  Except as specifically otherwise provided in this Section
13.9, any amendment to or consent or waiver under this Agreement or any Loan
Document that purports to accomplish any of the following must be by an
instrument in writing executed by Borrower and executed (or approved, as the
case may be) by Administrative Agent and each Lender (other than any Defaulting
Lender): (i) extends the Termination Date (except as set forth in Section 3.20);
(ii) extends the due date or decreases the amount of any scheduled payment or
amortization of the Obligation beyond the date specified in the Loan Documents;
(iii) decreases any rate or amount of interest, fees, principal, or other sums
payable to any Credit Party under this Agreement (except such reductions as are
contemplated by this Agreement); (iv) changes the definition of "Commitment,"
"Historical Value," "Implied Value," "Pool Consolidated Affiliates,"  "Pro
Rata," "Pro Rata Part," "Required Lenders," or "Total Commitment;" (v) amends or
waives the requirements of Section 7.15; (vi) waives the requirement of,
compliance with, amends, or fully or partially releases any guaranty or any
substantial part of any collateral, if any (except as expressly permitted by the
terms of the Loan Documents); (vii) permits Borrower to assign any of its rights
hereunder; or (viii) changes this clause (b) or any other matter specifically
requiring the consent of all Lenders under this Agreement.

     (c) Administrative Agent.  No amendment, modification, consent or waiver
which modifies the rights, duties, or obligations of any Agent shall be
effective without the consent of such Agent.

     (d) Conflicts.  Any conflict or ambiguity between the terms and provisions
of this Agreement and terms and provisions in any other Loan Document is
controlled by the terms and provisions of this Agreement.

     (e) Course of Dealing.  No course of dealing or any failure or delay by any
Credit Party or any of its respective Representatives with respect to exercising
any Right of such Credit Party under this Agreement operates as a waiver
thereof.  Any waiver will be effective only in the specific instance and for the
specific purpose for which it is given.

      13.10 Multiple Counterparts. Any Loan Document may be executed in a number
of identical counterparts, each of which shall be deemed an original for all
purposes and all of which constitute, collectively, one agreement; but, in
making proof thereof, it shall not be necessary to produce or account for more
than one counterpart. Each Lender need not execute the same counterpart of this
Agreement so long as identical counterparts are executed by Borrower, each
Lender, and each Agent.  This Agreement shall become effective when counterparts
of this Agreement have been executed and delivered to Administrative Agent by
each Lender, each Agent, and Borrower, or, in the case only of the Credit
Parties, when 

                                       54
<PAGE>
 
Administrative Agent has received telecopied, telexed, or other evidence
satisfactory to it that each Credit Party has executed and is delivering to
Administrative Agent a counterpart of this Agreement.

      13.11 Successors and Assigns; Participations.

     (a) Each Loan Document binds and inures to the benefit of the parties
thereto, any intended beneficiary thereof, and each of their respective
successors and permitted assigns.  No Lender may, without the prior written
consent of Administrative Agent and, so long as no Default has occurred and is
continuing, Borrower, transfer, pledge, assign, sell any participation in, or
otherwise encumber its portion of the Obligation, except as specifically
permitted by this Section 13.11.

     (b) Subject to the provisions of this Section 13.11 and in accordance with
applicable Law, any Lender having a Commitment equal to or greater than
$25,000,000, or if the Total Commitments have been terminated, then Notes having
outstanding Principal Debt equal to or greater than $25,000,000, may, in the
ordinary course of its commercial banking business, at any time sell to one or
more Persons (each a "Participant") participating interests in its portion of
the Obligation; provided that (i) each such participation is not less than
$10,000,000, (ii) except in the case of participations of Competitive Borrowings
or to any of such Lender's Affiliates, Administrative Agent and, so long as no
Default has occurred and is continuing, Borrower have consented to such
participation, such consents not to be unreasonably withheld, and (iii) after
giving effect to such participation, the Lender granting such participation
shall retain a Commitment of at least $15,000,000, or if the Total Commitments
have been terminated, then Notes having outstanding Principal Debt of at least
$15,000,000.  The selling Lender shall remain a "Lender" under this Agreement
(and the Participant shall not constitute a "Lender" under this Agreement) and
its obligations under this Agreement shall remain unchanged.  The selling Lender
shall remain solely responsible for the performance of its obligations under the
Loan Documents and shall remain the holder of its share of the Principal Debt
for all purposes under this Agreement.  Borrower and Administrative Agent shall
continue to deal solely and directly with the selling Lender in connection with
such Lender's Rights and obligations under the Loan Documents.  Participants
have no Rights under the Loan Documents, other than certain voting Rights as
provided below.  Subject to the following, each Lender may obtain (on behalf of
its Participants) the benefits of Section 3 with respect to all participations
in its part of the Obligation outstanding from time to time so long as Borrower
is not obligated to pay any amount in excess of the amount that would be due to
such Lender under Section 3 calculated as though no participations have been
made.  No Lender may sell any participating interest under which the Participant
has any Rights to approve any amendment, modification or waiver of any Loan
Document, except to the extent the amendment, modification or waiver extends the
due date for payment of any principal, interest or fees due under the Loan
Documents, reduces the interest rate or the amount of principal or fees
applicable to the Obligation (except reductions contemplated by this Agreement),
or releases any guaranty or any substantial part of the collateral, if any, for
the Obligation.  However, if a Participant is entitled to the benefits of
Section 3 or a Lender grants Rights to its Participants to approve amendments to
or waivers of the Loan Documents respecting the matters described in the
previous sentence, then such Lender must include a voting mechanism in the
relevant participation agreement whereby a majority of its portion of the
Obligation (whether held by it or participated) shall control the vote for all
of such Lender's portion of the Obligation.

     (c) Subject to the provisions of this Section 13.11, any Lender may at any
time, in the ordinary course of its commercial banking business, (i) without the
consent of Borrower or Administrative Agent, assign all or any part of its
Rights and obligations under the Loan Documents to any of its Affiliates so long
as such Affiliate is an Eligible Institution (each a "Purchaser") and (ii) upon
the prior written consent of Administrative Agent, and so long as no Default has
occurred and is continuing, Borrower, such consents 

                                       55
<PAGE>
 
not to be unreasonably withheld, assign to any other Eligible Institution (each
of which is also a "Purchaser") a proportionate part (not less than $10,000,000
and an integral multiple of $1,000,000, or if less, all of the assigning
Lender's Commitment or, if the Total Commitments have been terminated, Principal
Debt) of its Rights and obligations under the Loan Documents; provided that (x)
each such assignment shall exclude Competitive Borrowings, unless the assigning
Lender is selling all of its Rights and obligations under the Loan Documents,
and (y) after giving effect to such assignment, unless the assigning Lender is
assigning all of its Rights and Commitments hereunder, the Lender granting such
assignment shall retain a Commitment of at least $15,000,000, or if the Total
Commitments have been terminated, then Notes having outstanding Principal Debt
of at least $15,000,000. Notwithstanding the foregoing, each Agent shall, at all
times prior to its resignation or replacement as an Agent hereunder, retain a
minimum Commitment of $25,000,000, or if the Total Commitments have been
terminated, then Notes having outstanding Principal Debt of at least
$25,000,000. In each case, the Purchaser shall assume those Rights and
obligations under an assignment agreement substantially in the form of Exhibit
D. Upon (i) delivery of an executed copy of the assignment agreement to Borrower
and Administrative Agent and (ii) payment of a fee of $3,000 from the transferor
to Administrative Agent, from and after the assignment's effective date (which
shall be after the date of delivery), the Purchaser shall for all purposes be a
Lender party to this Agreement and shall have all the Rights and obligations of
a Lender under this Agreement to the same extent as if it were an original party
to this Agreement with commitments as set forth in the assignment agreement, and
the transferor Lender shall be released from its obligations under this
Agreement to a corresponding extent, and, except as provided in the following
sentence, no further consent or action by Borrower, Lenders, or any Agent shall
be required. Upon the consummation of any transfer to a Purchaser under this
clause (c), the then-existing Schedule 1 shall automatically be deemed to
reflect the name, address, and Commitment of such Purchaser, Administrative
Agent shall deliver to Borrower and Lenders an amended Schedule 1 reflecting
those changes, Borrower shall execute and deliver to each of the transferor
Lender and the Purchaser a Revolving Credit Note in the face amount of its
respective Commitment following transfer, and, upon receipt of its new Revolving
Credit Note, the transferor Lender shall return to Borrower the Revolving Credit
Note previously delivered to it under this Agreement. A Purchaser is subject to
all the provisions in this Section as if it were a Lender signatory to this
Agreement as of the date of this Agreement.

     (d) Any Lender may at any time, without the consent of Borrower or
Administrative Agent, assign all or any part of its Rights under the Loan
Documents to a Federal Reserve Bank without releasing the transferor Lender from
its obligations thereunder.

     (e) Notwithstanding any contrary provision in this Agreement, a Lender may
not sell or participate any of its interests for a purchase price that, directly
or indirectly, reflects a discount from face value, without first offering the
sale or participation to the other Lenders on a Pro Rata basis (which must be
accepted or rejected within five (5) Business Days after the offer).

     (f) Borrower is 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 pursuant to this Section 13.11 is received by Borrower.

      13.12 Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances.  Borrower's obligations under the Loan Documents remain in full
force and effect until the Total Commitment is terminated and the Obligation is
paid in full (except for provisions under the Loan Documents which by their
terms expressly survive payment of the Obligation and termination of the Loan
Documents).  If at any time any payment of the principal of or interest on any
Note or any other amount payable by Borrower or any other obligor on the
Obligation under any Loan Document is rescinded or must 

                                       56
<PAGE>
 
be restored or returned upon the insolvency, bankruptcy or reorganization of
Borrower or otherwise, the obligations of Borrower under the Loan Documents with
respect to that payment shall be reinstated as though the payment had been due
but not made at that time.

      13.13 Confidentiality.  Each Lender agrees to hold any confidential
information which (a) it has received prior to the Closing Date from Borrower
which is confidential and is not otherwise publicly available, and (b) it may
receive from Borrower pursuant to this Agreement after the Closing Date which
Borrower has marked "confidential" and is not otherwise publicly available, in
confidence, except (i) to other Lenders, (ii) to legal counsel, accountants, and
other professional advisors to such Lender who agree to be bound by the terms of
this Section, (iii) to regulatory officials, but only to the extent required by
such officials, (iv) upon prior notice to Borrower (which Lenders agree shall be
delivered as promptly as practicable), in connection with or response to
compliance with any Law or at the request of any Tribunal, but only to the
extent required by such Law or Tribunal, (v) upon prior notice to Borrower
(which Lenders agree shall be delivered as promptly as practicable), in
connection with any legal proceedings to which such Lender is a party, but only
to the extent required by such proceedings, and (vi) to prospective Participants
or Purchasers who agree to be bound by the terms of this Section.

      13.14 ARBITRATION.  ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES
HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY RELATED AGREEMENTS OR INSTRUMENTS, INCLUDING ANY CLAIM BASED ON
OR ARISING FROM AN ALLEGED TORT, SHALL BE DETERMINED BY BINDING ARBITRATION IN
ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (OR IF NOT APPLICABLE, THE
APPLICABLE STATE LAW), THE RULES OF PRACTICE AND PROCEDURE FOR THE ARBITRATION

     (b)  Principal Payments.  All unpaid Principal Debt is due and payable on
the Maturity Date.

     (c)  Voluntary Prepayment.  Borrower may voluntarily prepay all or any part
of the Principal Debt at any time without premium or penalty, subject to the
following conditions:

          (i)    Administrative Agent must receive Borrower's written prepayment
     notice by 11:00 a.m. on the Business Day preceding the date of prepayment,
     which shall specify the payment date and the Type and amount of the
     Borrowing(s) to be paid, and which shall constitute an irrevocable and
     binding obligation of Borrower to make a prepayment on the designated date;

          (ii)   each partial prepayment must be in the amount of $1,000,000 or
     a greater integral multiple of $100,000, or, if less, the unpaid Principal
     Debt; and

          (iii)  Borrower shall pay any related Funding Loss upon demand.

     3.3  Interest Options.  Except as specifically otherwise provided,
Borrowings shall bear interest at an annual rate equal to the lesser of (a)
either the Base Rate plus the Applicable Margin, or the Eurodollar Rate plus the
Applicable Margin (in each case as designated or deemed designated by Borrower
and, in the case of Eurodollar Borrowings, for the Interest Period designated by
Borrower), and (b) the Maximum Rate.  Each change in the Base Rate and Maximum
Rate is effective, without notice to Borrower or any other Person, upon the
effective date of such change.

     3.4  Selection of Interest Option.

     (a)  When Borrower requests any Eurodollar Borrowing, Borrower shall elect
the applicable interest period (each an "Interest Period"), which may be, at
Borrower's option, seven (7) days, fourteen (14) days, twenty-one (21) days, one
(1) month, two (2) months, or three (3) months subject to the following
conditions: (i) each Interest Period applicable to any Borrowing commences on
the date of the initial advance of the Term Loan and thereafter the day on or
after the day when the next preceding applicable Interest Period expires; (ii)
if any Interest Period for a Eurodollar Borrowing begins on a day for which
there exists no numerically corresponding Business Day in the calendar month at
the end of the Interest Period ("Ending Calendar Month"), then the Interest
Period ends on the next succeeding Business Day of the Ending Calendar Month,
unless there is no succeeding Business Day in the Ending Calendar Month in which
case the Interest Period ends on the next preceding Business Day of the Ending
Calendar Month; (iii) no Interest Period for any portion of any Term Loan may
extend beyond the scheduled repayment date for that portion of the Term Loans;
(iv) there may not be in effect at any one time more than five (5) Interest
Periods; (v) each Eurodollar Borrowing with respect to the Term Loans shall be
in the amount of $1,000,000 or a greater integral multiple of $100,000; and (vi)
Borrower may not request a Eurodollar Borrowing if the interest rate applicable
thereto under Section 3.3 would exceed the Maximum Rate in effect on the first
(1st) day of the Interest Period applicable to such Borrowing.

                                       18
<PAGE>
 
     (b)  Borrower may (i) on the last day of the applicable Interest Period (or
at any other time, subject to payment of any Funding Loss) convert all or part
of a Eurodollar Borrowing to a Base Rate Borrowing, (ii) at any time convert all
or part of a Base Rate Borrowing to a Eurodollar Borrowing, and (iii) on the
last day of an Interest Period, elect a new Interest Period for a Eurodollar
Borrowing; provided that no conversions to or elections of new Interest Periods
for any Eurodollar Borrowings shall be permitted while a Default exists unless
Required Lenders otherwise consent in writing.  Any such conversion may be
accomplished by delivering a Conversion Request to Administrative Agent no later
than 11:00 a.m. (A) on the third (3rd) Business Day before (x) the conversion
date for conversion to a Eurodollar Borrowing, and (y) the last day of the
Interest Period, for the election of a new Interest Period, and (B) one (1)
Business Day before the last day of the Interest Period for conversion to a Base
Rate Borrowing.  Absent Borrower's notice of conversion or election of a new
Interest Period, a Eurodollar Borrowing shall be converted to a Base Rate
Borrowing when the applicable Interest Period expires.

     3.5  Default Rate.  If permitted by Law, all past-due Principal Debt and
past-due interest shall bear interest from the date due (stated or by
acceleration) at the Default Rate until paid, regardless 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, then 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 permitted by applicable Law, 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.

     (a)  Interest will be calculated on the basis of actual number of days
elapsed (including the first day but excluding the last day) but computed as if
each calendar year consisted of 360 days in the case of all Eurodollar
Borrowings (unless the calculation would result in an interest rate greater than
the Maximum Rate, in which event interest will be calculated on the basis of a
year of 365 or 366 days, as the case may be), and 365 or 366 days, as the case
may be, in the case of Base Rate Borrowings.  All interest rate determinations
and calculations by Administrative Agent are conclusive and binding absent
manifest error.

     (b)  The provisions of this Agreement relating to calculation of the Base
Rate and the Eurodollar Rate are included only for the purpose of determining
the rate of interest or other amounts to be paid under this Agreement that are
based upon those rates.  Each Lender may fund and maintain its funding of all or
any part of each Borrowing as it selects.

     3.8  Maximum Rate.  Regardless of any provision contained in any Loan
Document or any document related thereto, it is the intent of the parties to
this Agreement that no Credit Party contract for, charge, take, reserve,
receive, or apply, as interest on all or any part of the Obligation any amount
in excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable Law, and, if any Credit Party ever does
so, then any excess shall be treated as a partial repayment

                                       19
<PAGE>
 
or prepayment of principal and any remaining excess shall be refunded to
Borrower.  In determining if the interest paid or payable exceeds the Maximum
Rate, Borrower and the Credit Parties shall, to the maximum extent permitted
under applicable Law, (a) treat all Borrowings as but a single extension of
credit (and the Credit Parties and Borrower agree that is the case and that
provision in this Agreement for multiple Borrowings is for convenience only),
(b) characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (c) exclude voluntary repayments or prepayments and their
effects, and (d) amortize, prorate, allocate, and spread the total amount of
interest throughout the entire contemplated term of the Obligation.  However, if
the Obligation is paid in full before the end of its full contemplated term, and
if the interest received for its actual period of existence exceeds the Maximum
Amount, then the Credit Parties shall refund any excess (and the Credit Parties
may not, to the extent permitted by Law, be subject to any penalties provided by
any Laws for contracting for, charging, taking, reserving or receiving interest
in excess of the Maximum Amount).  If the Laws of the State of Texas are
applicable for purposes of determining the "Maximum Rate" or the "Maximum
Amount," then those terms mean the "weekly ceiling" from time to time in effect
under Article 5069-1D.009, Title 79, Revised Civil Statutes of Texas, as
amended.

     3.9  Order of Application.

     (a)  If no Default exists, any payment shall be applied to the Obligation
in the order and manner specified by Borrower.

     (b)  If a Default exists, any payment (including proceeds from the exercise
of any Rights) shall be applied in the following order:  (i) to all fees and
expenses for which the Credit Parties have not been paid or reimbursed in
accordance with the Loan Documents (and if such payment is less than all unpaid
or unreimbursed fees and expenses, then the payment 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; and (iii) to the remaining Obligation
in the order and manner as the Required Lenders deem appropriate.

All payments to or for the account of Lenders shall be shared by such Lenders on
a Pro Rata basis.

     3.10 Offset.  If a Default exists, then each Lender is entitled, but is not
obligated, to exercise (for the benefit of all Lenders in accordance with
Section 3.16) the Rights of offset and banker's Lien against each and every
account and other property, or any interest therein, that Borrower 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.

     3.11 Booking Borrowings.  To the extent permitted by Law, any Lender may
make, carry, or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office of any of its Affiliates.  However, no Affiliate is
entitled to receive any greater payment under this Agreement than the transferor
Lender would have been entitled to receive with respect to those Borrowings.

     3.12 Basis Unavailable or Inadequate for the Eurodollar Rate.  If, prior to
the first (1/st/) day of any Interest Period, (a) Administrative Agent
determines that the basis for determining the applicable rate is not available,
or (b) Lenders holding fifty percent (50%) of the Principal Debt of the Term
Loans notify Administrative Agent that such Lenders have determined that the
rate determined by Administrative Agent as the Eurodollar Rate for any Interest
Period does not accurately reflect the cost to such Lenders of making or
converting Borrowings at that rate for such Interest Period, then Administrative
Agent shall promptly notify Borrower and Lenders of such determination (which is
conclusive and binding on Borrower absent manifest error), and all affected
Borrowings shall bear interest at the sum of the Base Rate plus the

                                       20
<PAGE>
 
Applicable Margin.  Until Administrative Agent notifies Borrower that such
circumstances no longer exist, Lenders' commitments under this Agreement to
make, or to convert to, affected Borrowings will be suspended.

     3.13 Additional Costs.  With respect to any Law, requirement, request,
directive, or change affecting banking institutions generally:

     (a)  Eurocurrency Reserves.  If any Lender shall be required under any
Reserve Requirement to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency Liabilities, then (i) such Lender
(through Administrative Agent) shall, within sixty (60) days after the end of
any Interest Period with respect to any Eurodollar Borrowing during which such
Lender was so required to maintain reserves, deliver to Borrower a certificate
stating (A) that such Lender was required to maintain reserves and as a result
such Lender incurred additional costs in connection with making such Eurodollar
Borrowing and (B) in reasonable detail, such Lender's computations of the amount
of additional interest payable by Borrower, pursuant to the provisions below,
and (ii) Borrower shall, within ten (10) days after receipt of any such
certificate, pay to Administrative Agent, for the account of such Lender,
additional interest on the unpaid principal amount of such Eurodollar Borrowing
of such Lender made to it outstanding during the Interest Period with respect to
which the above-referenced certificate was delivered to Administrative Agent, at
a rate per annum equal to the difference obtained by subtracting (x) the
Eurodollar Rate for such Interest Period from (y) the rate obtained by dividing
such Eurodollar Rate by a percentage equal to 100% minus the Reserve Requirement
of such Lender for such Interest Period.  The amount of interest payable by
Borrower to any Lender as stated in any certificate delivered to Administrative
Agent  pursuant to the provisions of this Section 3.13(a) shall be conclusive
and binding for all purposes, absent manifest error.  The provisions of this
Section 3.13(a) shall survive the termination of this Agreement.

     (b)  Reserves.  With respect to any Eurodollar Borrowing, if (i) any change
in present Law, any change in the interpretation or application of any present
Law, or any future Law imposes, modifies, or deems applicable (or if compliance
by any Lender with any such requirement of any Tribunal results in) any such
requirement that any reserves (including any marginal, emergency, supplemental,
or special reserves) be maintained, and (ii) those reserves reduce any sums
receivable by such Lender under this Agreement or increase the costs incurred by
such Lender in advancing or maintaining any portion of any Eurodollar Borrowing,
then (unless the effect is already reflected in the rate of interest then
applicable under this Agreement) such 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 Borrower shall within ten (10) days after receipt of such certificate pay
that amount to Administrative Agent, for the account of such Lender.  Such
Lender shall notify Administrative Agent and Borrower of any such determination
as soon as practicable (but in any event within 120 days) after such Lender
obtains actual knowledge of the event or condition prompting such Lender to make
such determination, and Borrower shall not be liable for any such amount or
amounts that accrue between the date such notification is required to be given
and the date notice was actually given.  The provisions of and undertakings and
indemnification set forth in this Section 3.13(b) shall survive the satisfaction
and payment of the Obligation and termination of this Agreement.

     (c)  Capital Adequacy.  With respect to any Borrowing, if any change in
present Law or any future Law regarding capital adequacy or compliance by any
Credit Party with any request, directive, or requirement now existing or
hereafter imposed by any Tribunal regarding capital adequacy, or any change in
its written policies or in the risk category of this transaction, 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

                                       21
<PAGE>
 
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, use 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 such Credit Party (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 within ten (10) days after receipt of such certificate pay that
amount to Administrative Agent for the account of such Credit Party.  Such
Credit Party shall notify Administrative Agent and Borrower of any such
determination as soon as practicable (but in any event within 120 days) after
such Lender obtains actual knowledge of the event or condition prompting such
Credit Party to make such determination, and Borrower shall not be liable for
any such amount or amounts that accrue between the date such notification is
required to be given and the date notice was actually given.  The provisions of
and undertakings and indemnification set forth in this Section 3.13(c) shall
survive the satisfaction and payment of the Obligation and termination of this
Agreement.

     (d)  Taxes.  Any Taxes payable by any Credit Party or ruled (by a Tribunal)
payable by any Credit Party in respect of this Agreement or any other Loan
Document shall, if permitted by Law, be paid by Borrower, together with interest
and penalties, if any (except for (i) (1) Taxes imposed on or measured by the
overall net income of such Credit Party, (2) franchise or similar taxes of such
Credit Party, and (3) amounts requested to be withheld for Taxes pursuant to the
last sentence of Section 3.17, and (ii) such interest and penalties incurred as
a result of the gross negligence or willful misconduct of any Credit Party).
Such Credit Party (through Administrative Agent) shall notify Borrower and
deliver to Borrower a certificate setting forth in reasonable detail the
calculation of the amount of payable Taxes, which certificate is conclusive and
binding (absent manifest error), and Borrower shall within ten (10) days after
receipt of such certificate pay that amount to Administrative Agent for its
account or the account of such Credit Party, as the case may be.  If such Credit
Party subsequently receives a refund of the Taxes paid to it by Borrower, then
the recipient shall promptly pay the refund to Borrower.

     3.14 Change in Law.  If any Law makes it unlawful for any Lender to make or
maintain Eurodollar Borrowings, then such Lender shall promptly notify Borrower
and Administrative Agent, and with respect to such Lender's Borrowings (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,
and Borrower shall pay any related Funding Loss, or (ii) if not prohibited by
Law, 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 not
resolve the unlawfulness, then Borrower shall promptly prepay the Borrowing,
without penalty, together with any related Funding Loss.

     3.15 Funding Loss.  Borrower Agrees To Indemnify Each Lender Against, And
Pay To Each Lender Within Ten (10) Days After Demand, Any Funding Loss Of Such
Lender.  When any Lender demands that Borrower pay any Funding Loss, such Lender
shall deliver to Borrower and Administrative Agent a certificate setting forth
in reasonable detail the basis for such Funding Loss and the calculation of the
amount, which calculation is conclusive and binding absent manifest error.  The
provisions of and undertakings and indemnification set forth in this Section
3.15 shall survive the satisfaction and payment of the Obligation and
termination of this Agreement.

     3.16 Sharing of Payments, etc.  If any Lender obtains any amount (whether
voluntary, involuntary, or otherwise, including as a result of exercising its
Rights under Section 3.10) that exceeds the

                                       22
<PAGE>
 
part of that payment that such Lender is entitled to receive under the Loan
Documents, then such Lender shall purchase from the other Lenders participations
that will cause the purchasing Lender to share the excess amount ratably with
each other Lender.  If all or any portion of any excess payment 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
3.16 may, to the fullest extent permitted by Law, exercise all of its Rights of
payment (including the Right of offset) with respect to that participation as
fully as if such Lender were the direct creditor of Borrower in the amount of
that participation.

     3.17 Foreign Lenders.  Each Lender that is organized under the Laws of any
jurisdiction other than the United States of America or any State thereof (a)
represents to Administrative Agent and Borrower that (i) no Taxes are required
to be withheld by Administrative Agent or Borrower with respect to any payments
to be made to it in respect of the Obligation, and (ii) it has furnished to
Administrative Agent and Borrower two (2) duly completed copies of United States
Internal Revenue Service Form 4224, Form 1001, Form W-8, or any other tax form
acceptable to Administrative Agent (wherein it claims entitlement to complete
exemption from United States federal withholding tax on all interest payments
under the Loan Documents), and (b) covenants to (i) provide Administrative Agent
and Borrower a new tax form upon the expiration or obsolescence of any
previously delivered form according to Law, duly executed and completed by it,
and (ii) comply from time to time with all Laws with regard to the withholding
tax exemption.  If any of the foregoing is not true or the applicable forms are
not provided, then Borrower or Administrative Agent (without duplication) may
deduct and withhold from interest payments under the Loan Documents United
States federal income tax at the full rate applicable under the Code.

     3.18 Extension.  Borrower may request that the Initial Maturity Date be
extended to the Extended Maturity Date by making such request in writing (an
"Extension Request") to Administrative Agent on or before August 31, 1999.  The
Initial Maturity Date shall be extended to the Extended Maturity Date only if
(a) Borrower pays to Administrative Agent the extension fee set forth in Section
4.3, and (b) no Default or Potential Default exists at the time of Borrower's
request for such extension.

SECTION 4  FEES.
- ---------  ---- 

     4.1   Treatment of Fees.  The fees described in this Section 4 (a) are not
compensation for the use, detention, or forbearance of money, (b) are in
addition to, and not in lieu of, interest and expenses otherwise described in
this Agreement, (c) are payable in accordance with Section 3.1(b), (d) are non-
refundable, (e) to the fullest extent permitted by Law, bear interest, if not
paid when due, at the Default Rate, and (f) are 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 360 days, unless
computation would result in an interest rate in excess of the Maximum Rate in
which event the computation is made on the basis of a year of 365 or 366 days,
as the case may be.  The fees described in this Section 4 are in all events
subject to the provisions of Section 3.8.

     4.2   Commitment Fees.
 
           (a)    Borrower agrees to pay to Administrative Agent the commitment
     fees set forth in the separate letter agreement dated of even date
     herewith, which fees shall be for the account of Administrative Agent and
     for the account of Lenders as shall be agreed between Administrative Agent
     and the other Lenders.

                                       23
<PAGE>
 
           (b)    Borrower shall pay to Administrative Agent, for the ratable
     account of each Lender,  a facility fee equal to the product of (i) the
     average daily Principal Debt for the period from and including the Closing
     Date up to but excluding the Maturity Date, times (ii) a rate per annum
     equal to the Applicable Facility Fee Percentage.  Such facility fee shall
     be payable quarterly in arrears on  the first (1/st/) day of each January,
     April, July, and October during the term hereof and on the Maturity Date,
     commencing on July 1, 1999.

     4.3   Extension Fee. Upon the extension of the Initial Maturity Date to the
Extended Maturity Date, as provided in Section 3.18, Borrower agrees to pay to
Administrative Agent, for the ratable account of Lenders, an extension fee equal
to one-half of one percent (0.50%) of the unpaid Principal Debt on the Initial
Maturity Date.

SECTION 5  CONDITIONS PRECEDENT.  Lenders will not be obligated to fund the Term
- ---------  --------------------                                                 
Loans unless (a) Administrative Agent has timely received all of the items
described on Schedule 5, (b) all of the representations and warranties of
Borrower in the Loan Documents are true and correct in all material respects,
(c) no Default or Potential Default exists, and (d) the funding of the Term
Loans is permitted by Law.

SECTION 6  REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants to
- ---------  ------------------------------                                      
the Credit Parties as follows:

     6.1   Purpose of Credit Facility.  Borrower will use proceeds of the
Borrowings hereunder to prepay Indebtedness and general trust purposes.
Borrower is not engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying any
"margin stock" within the meaning of Regulation U of the Board of Governors of
the Federal Reserve System, as amended.  No part of the proceeds of any
Borrowing will be used, directly or indirectly, for a purpose that violates any
Law, including the provisions of Regulation U.

     6.2   Corporate Existence, Good Standing, Authority and Compliance.  Each
Company is duly formed, validly existing, and in good standing under the Laws of
the jurisdiction in which it is incorporated or formed as identified on Schedule
6.2 (as supplemented from time to time).  Each Company (a) is duly qualified to
transact business and is in good standing as a foreign trust, corporation,
partnership, limited liability company, or other entity in each jurisdiction
where the nature and extent of its business and properties require due
qualification and good standing, (b) possesses all requisite authority, permits,
and power to conduct its business as is now being, or is contemplated by this
Agreement to be, conducted, and (c) is in compliance with all applicable Laws,
except in any such case where violation of the foregoing could not reasonably be
expected to result in a Material Adverse Event.

     6.3   Affiliates.  As of the date of this Agreement, Borrower has no
Consolidated Affiliates or Unconsolidated Affiliates except as disclosed on
Schedule 6.2 (as supplemented from time to time to reflect changes as a result
of transactions permitted by this Agreement).

     6.4   Authorization and Contravention.  The execution and delivery by
Borrower of each Loan Document or related document to which it is a party and
the performance by it of its obligations thereunder (a) are within its trust
power, (b) have been duly authorized by all necessary trust action, (c) require
no action by or filing with any Tribunal (other than any action or filing that
has been taken or made on or before the date of this Agreement), (d) do not
violate any provision of its declaration of trust or bylaws, (e) do not violate
any provision of Law or order of any Tribunal applicable to it, (f) do not
violate any material

                                       24
<PAGE>
 
agreements to which it is a party, or (g) do not result in the creation or
imposition of any Lien on any asset of any Company, except in such case where
failure to do so could not reasonably be expected to result in a Material
Adverse Event.

     6.5   Binding Effect.  Upon execution and delivery by all parties thereto,
each Loan Document to which it is a party will constitute a legal and binding
obligation of Borrower, enforceable against it in accordance with its terms,
subject to applicable Debtor Relief Laws and general principles of equity.

     6.6   Financial Statements; Fiscal Year.  The Current Financials were
prepared in accordance with GAAP (except that quarterly Financial Statements may
omit footnotes required by GAAP) and present fairly, in all material respects,
the consolidated financial condition, results of operations, and cash flows of
the Companies as of, and for the portion of the fiscal year ending on, the date
or dates thereof (subject only to normal audit adjustments).  All material
liabilities of the Companies as of the date or dates of the Current Financials
are reflected therein or in the notes thereto.  Except for transactions directly
related to, or specifically contemplated by, the Loan Documents or disclosed in
the Current Financials, no subsequent material adverse changes have occurred in
the consolidated financial condition of the Companies from that shown in the
Current Financials, nor has any Company incurred any subsequent material
liability.  The fiscal year of the Companies ends on December 31.

     6.7   Litigation.  Except as disclosed on Schedule 6.7 and as otherwise
disclosed pursuant to Section 7.1(d)(i), no Company is subject to, or aware of
the threat of, any Litigation that is reasonably likely to be determined
adversely to such Company and which, if so adversely determined, is reasonably
likely to result in a Material Adverse Event.  Except as permitted under Section
10.4, no outstanding and unpaid judgments against any Company exist.

     6.8   Taxes.

     (a)   All Tax returns of the Companies required to be filed have been filed
(or extensions have been granted) before delinquency, except for returns for
which the failure to file could not reasonably be expected to result in a
Material Adverse Event, and all Taxes imposed upon the Companies that are due
and payable have been paid before delinquency or are being contested in good
faith by appropriate proceedings diligently conducted and for which reserves in
accordance with GAAP or otherwise reasonably acceptable to Administrative Agent
have been provided.

     (b)   As of the date hereof, no United States federal income tax returns of
the "affiliated group" (as defined in the Code) of which Borrower is a member
have been examined and closed.  The members of such affiliated group have filed
all United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by or any of them.  The
charges, accruals and reserves on the books of Borrower in respect of taxes or
other governmental charges are, in the opinion of Borrower, adequate.

     (c)   Borrower qualifies as a REIT.

     6.9   Environmental Matters.  Except as disclosed on Schedule 6.9, and
except for any of the following which could not reasonably be expected to result

exists that adversely affects any Company's properties or operations, (b) no
Company has received any report of any Company's violation of any Environmental
Law, (c) no Company knows that any Company is under any obligation to remedy any
violation of any

                                       25

Environmental Law, or (d) no facility of any Company is used for, or to the
knowledge of any Company has been used for, storage, treatment, or disposal of
any Hazardous Substance,  except for (i) the storage and use of cleaning and
maintenance materials, used and stored in commercially reasonable quantities and
in compliance with applicable Environmental Laws, and (ii) light manufacturing
and distribution activities of tenants, in compliance with applicable
Environmental Laws, provided that such tenants are not primarily engaged in the
treatment, processing, recycling or disposal of any Hazardous Substance or in
any other activity that would give rise to the release of any Hazardous
Substance on such facility.  Each Company has taken prudent steps to determine
that its properties and operations do not violate any Environmental Law, other
than violations that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Event.

     6.10  Pension Plans.  Except as disclosed on the Financial Statements of
Borrower dated as of December 31, 1998, and except to the extent that any such
termination, liability, penalty, or fine would not (either individually or in
the aggregate) reasonably be expected to have a Material Adverse Event, (a) no
steps have been taken to terminate any Pension Plan, and no contribution failure
has occurred with respect to any Pension Plan sufficient to give rise to a Lien
under any Applicable Pension Laws, (b) no condition exists or event or
transaction has occurred with respect to any Pension Plan which could reasonably
be expected to result in the incurrence by Borrower or any ERISA Affiliate of
any material liability with respect to any contribution thereto, fine, or
penalty, and (c) neither Borrower nor any ERISA Affiliate has any material
contingent liability with respect to any post-retirement benefit under a Pension
Plan.

     6.11   Properties; Liens.  Each Company has good title to all its property
reflected on the Current Financials (except for property that is obsolete or
that has been disposed in the ordinary course of business or, after the date of
this Agreement, as otherwise permitted by Section 8.8 or Section 8.9).  Except
for Permitted Liens and Liens on Properties acquired by a Company, provided that
such Liens are not incurred in contemplation of any Company's acquisition of
such Properties, no Lien exists on any Property of any Company in the Pool, and
the execution, delivery, performance, or observance of the Loan Documents will
not require or result in the creation of any Lien on any of any Company's
Property in the Pool.

     6.12   Locations.  Borrower's chief executive office is located at the
address on Schedule 6.12 (as supplemented from time to time).  Borrower's books
and records are located at its chief executive office.

     6.13   Government Regulations. No Company is subject to regulation under
the Investment Company Act of 1940, as amended, or the Public Utility Holding
Company Act of 1935, as amended.

     6.14   Transactions with Affiliates.  Except as disclosed on Schedule 6.14
(as supplemented from time to time) (if the disclosures are approved by
Administrative Agent) or as permitted by Section 8.4, no Company is a party to a
material transaction with any of its Affiliates, other than transactions 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.

     6.15   Insurance.  Each Company maintains 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 operates) insurance
concerning its properties and businesses against casualties and contingencies
and of types and in amounts (and with co-insurance and deductibles) as is
customary in the case of similar businesses.

                                       26
<PAGE>
 
     6.16   Labor Matters.  No actual or, to Borrower's knowledge, threatened
strikes, labor disputes, slow downs, walkouts, or other concerted interruptions
of operations by the employees of any Company that could reasonably be expected
to result in a Material Adverse Event exist. All payments due from each Company
for employee health and welfare insurance have been paid or accrued as a
liability on its books, other than non-payments that are not, individually or
collectively, reasonably expected to result in a Material Adverse Event.

     6.17   Solvency.  On each Borrowing Date, Borrower is, and after giving
effect to the requested Borrowing will be, Solvent.

     6.18   Full Disclosure.  Each material fact or condition relating to the
financial condition or business of any Company which could reasonably be
expected to result in a Material Adverse Event has been disclosed to
Administrative Agent. All information previously furnished, furnished on the
date of this Agreement, and furnished in the future, by any Company to
Administrative Agent in connection with the Loan Documents (a) was, is, and will
be, true and accurate in all material respects or based on good faith estimates
on the date the information is stated or certified, and (b) did not, does not,
and will not, fail to state any material fact the omission of which would
otherwise make any such information materially misleading, in each case taken as
a whole.

     6.19   Exemption from ERISA; Plan Assets.  The assets of Borrower are not
"plan assets" as defined in 29 C.F.R. (S) 2510.3-101(a)(1) (or any successor
regulation) of any Pension Plan.

     6.20   Minority Interests.  All Consolidated Affiliates of Borrower having
minority interests are set forth on Schedule 6.20 (as supplemented from time to
time).

     6.21   Year 2000 Compliance.  Borrower has (a) initiated a review and
assessment of all areas within each Company's business and operations (including
those affected by suppliers and vendors) that could be adversely affected by the
"Year 2000 Problem" (that is, the risk that computer applications used by any
Company (or its material suppliers and vendors) may be unable to recognize and
perform properly date-sensitive functions involving certain dates prior to and
any date after December 31, 1999), (b) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, and (c) to date, implemented
that plan in accordance with that timetable. Borrower reasonably believes that
all computer applications (including those of its material suppliers and
vendors) that are material to each Company's business and operations will on a
timely basis be able to perform properly date-sensitive functions for all dates
before and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
the extent that a failure to do so could not reasonably be expected to result in
a Material Adverse Event.

SECTION 11   RIGHTS AND REMEDIES.
- ----------   ------------------- 

     11.1   Remedies Upon Default.

     (a)    If a Default (i) occurs under Section 10.3(c) or (ii) occurs and is
continuing under Section 10.3(a), (b) or (d), the entire unpaid balance of the
Obligation automatically becomes due and payable without any action of any kind
whatsoever.

     (b)    If a Default occurs and is continuing, subject to the terms of
Section 12.3(b) and Section 12.10, Administrative Agent may, and upon the
request of Required Lenders shall, 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 balance of all or any part of the Obligation
immediately due and payable, whereupon it is due and payable; (ii) reduce any
claim to judgment; (iii) to the extent permitted by Law, exercise (or request
each Lender to, and each Lender is entitled to, exercise) the Rights of offset
or banker's Lien against the interest of each Company in and to every account
and other property of such Company that are in the possession of any Credit
Party to the extent of the full amount of the Obligation (and to the extent
permitted by Law, each Company is deemed directly obligated to each Credit Party
in the full amount of the Obligation for this purpose); and (iv) exercise any
and all other legal or equitable Rights afforded by the Loan Documents, the Laws
of the State of Texas, or any other applicable jurisdiction.

     11.2   Waivers.  To the extent permitted by Law, Borrower waives
presentment and demand for payment, protest, notice of intention to accelerate,
notice of acceleration, and notice of protest and nonpayment, 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, or by any release or change in any security for
the payment of all or any part of the Obligation.

                                       38
<PAGE>
 
     11.3   Performance by Administrative Agent.  If any covenant, duty, or
agreement of any Company is not performed in accordance with the terms of the
Loan Documents, then Administrative Agent may, while a Default exists, at its
option, perform or attempt to perform that covenant, duty or agreement on behalf
of such Company (and any amount expended by Administrative Agent in its
performance or attempted performance is payable by Borrower to Administrative
Agent on demand, becomes part of the Obligation, and bears interest at the
Default Rate from the date of Administrative Agent's expenditure until paid).
However, no Credit Party assumes or shall have, except by its express written
consent, any liability or responsibility for the performance of any covenant,
duty, or agreement of any Company.

     11.4   Not in Control.  None of the covenants or other provisions contained
in any Loan Document shall, or shall be deemed to, give any Credit Party the
Right to exercise control over the assets (including real property), affairs, or
management of any Company; the power of each Credit Party is limited to the
Right to exercise the remedies provided in this Section 11.

     11.5   Course of Dealing.  The acceptance by any Credit Party of any
partial payment on the Obligation shall not be deemed to be a waiver of any
Default then existing. No waiver by any Credit Party of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default. No delay
or omission by any Credit Party in exercising any Right under the Loan Documents
will impair that Right or be construed as 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 Loan
Documents or otherwise.

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

     11.7   Application of Proceeds.  Any and all proceeds ever received by any
Credit Party from the exercise of any Rights pertaining to the Obligation shall
be applied to the Obligation according to Section 3.11.

     11.8   Diminution in Value of Collateral.  No Credit Party has any
liability or responsibility whatsoever for any diminution in or loss of value of
any collateral now or hereafter securing payment or performance of all or any
part of the Obligation (other than diminution in or loss of value caused by its
gross negligence or willful misconduct).

     11.9   Certain Proceedings.  Borrower will promptly execute and deliver, or
cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers any
Credit Party reasonably requests in connection with the obtaining of any
consent, approval, registration, qualification, permit, license, or
authorization of any Tribunal or other Person necessary or appropriate for the
effective exercise of any Rights under the Loan Documents. Because Borrower
agrees that the Credit Parties' remedies at Law for failure of Borrower to
comply with the provisions of this paragraph would be inadequate and that
failure would not be adequately compensable in damages, Borrower agrees that the
covenants of this Section 11.9 may be specifically enforced.

SECTION 12   AGENTS AND LENDERS.
- ----------   ------------------ 

     12.1   Agents.

     (a)    Appointment.  Each Lender appoints Administrative Agent (and
Administrative Agent accepts appointment) as its nominee and agent, in its name
and on its behalf: (i) to act as its nominee and on its behalf in and under all
Loan Documents; (ii) to arrange the means whereby its funds are to be made
available to Borrower under the Loan Documents; (iii) to take any action that it
properly requests under the Loan Documents (subject to the concurrence of other
Lenders as may be required under the Loan Documents); (iv) to receive all
documents and items to be furnished to it under the Loan Documents; (v) to be
the secured party, mortgagee, beneficiary, recipient, and similar party in
respect of any collateral, if any, for the benefit of Lenders; (vi) to promptly
distribute to it all Financial Statements, notices received hereunder, and other
items specifically required to be delivered to it hereunder and, upon request,
such other material information, requests, documents, and items received from
Borrower under the Loan Documents; (vii) 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 accor dance with the terms of the Loan Documents; (viii) to
deliver to the appropriate Persons requests, demands, approvals, and consents
received from it; and (ix) to arrange for inspections pursuant to Section 7.4.
However, Administrative Agent may not be required to take any action that
exposes it to personal liability or that is contrary to any Loan Document or
applicable Law.

     (b)    Successor.  Administrative Agent may assign all of its Rights and
obligations as Administrative Agent under the Loan Documents to any of its
Affiliates, which Affiliate shall then be the successor Administrative Agent
under the Loan Documents. Administrative Agent may also voluntarily resign by
giving thirty (30) days' prior written notice to Borrower and Lenders, and shall
resign upon the request of the Required Lenders for cause (i.e., Administrative
Agent is continuing to fail to perform its responsibilities as Administrative
Agent under the Loan 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 the Required Lenders), then the Required Lenders shall (which, if no
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 the Required
Lenders fail to appoint a successor Administrative Agent within thirty (30) days
after the resigning Administrative Agent has given notice of resignation or the
Required Lenders have removed the resigning Administrative Agent, then the
resigning Administrative Agent may, on behalf of Lenders, appoint a successor
Administrative Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of condition)
and whose debt obligations (or whose parent's debt obligations) are rated not
less than Baa1 by Moody's or BBB+ by S & P. 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
as Administrative Agent under the Loan Documents, and each Lender shall execute
the documents that any Lender, the resigning or removed Administrative Agent, or
the successor Administrative Agent reasonably requests to reflect the change.
After any Administrative Agent's resignation or removal as Administrative Agent
under the Loan 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 Loan Documents. If Borrower fails to respond to any written request for any
consent required in this

                                       40
<PAGE>
 
Section 12.1(b) within ten (10) days after the date that Borrower receives such
request, then Borrower shall be deemed to have given its consent to such
request.

     (c)    Syndication Agent.  Syndication Agent, in such capacity, shall have
no rights, duties, or obligations hereunder, except as specifically provided in
this Agreement. Syndication Agent (i) may voluntarily resign by notice to
Administrative Agent, Lenders, and Borrower, and (ii) shall resign upon the
request of the Required Lenders for cause. Upon the resignation of Syndication
Agent, Administrative Agent may elect to designate a successor Syndication Agent
(which, if no Default or Potential Default exists, is subject to Borrower's
approval that may not be unreasonably withheld), which must be a Lender who is a
commercial bank having a combined capital and surplus of at least
$10,000,000,000 (as shown on its most recently published statement of condition)
and whose debt obligations (or whose parent's debt obligations) are rated not
less than Baa1 by Moody's or BBB+ by S & P.

     (d)    Documentation Agent.  Documentation Agent, in such capacity, shall
have no rights, duties, or obligations hereunder, except as specifically
provided in this Agreement. Documentation Agent (i) may voluntarily resign by
notice to Administrative Agent, Lenders, and Borrower, and (ii) shall resign
upon the request of the Required Lenders for cause. Upon the resignation of
Documentation Agent, Administrative Agent may elect to designate a successor
Documentation Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a Lender who is a commercial bank having a combined capital and surplus
of at least $10,000,000,000 (as shown on its most recently published statement
of condition) and whose debt obligations (or whose parent's debt obligations)
are rated not less than Baa1 by Moody's or BBB+ by S & P.

     12.2   Delegation of Duties; Reliance.  Lenders may perform any of their
duties or exercise any of their Rights under the Loan 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 Loan Documents by or
through their respective Representatives. The Credit Parties 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 any 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 any other Loan Document or (ii) any other writing if a
specific writing is required by this Agreement or any other Loan Document), (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 such Lender's
portion of the Obligation until that notice is given and received), (c) are not
deemed to have notice of the occurrence of a Default unless a responsible
officer of Administrative Agent, who handles matters associated with the Loan
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.

     12.3   Limitation of Administrative Agent's Liability.

     (a)    Exculpation.  Neither Administrative Agent nor any of its
representatives will be liable for any action taken or omitted to be taken by it
or them under the Loan Documents in good faith and believed

                                       41
<PAGE>
 
by it or them to be within the discretion or power conferred upon it or them by
the Loan 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 Representatives has a fiduciary
relationship with any Lender by virtue of the Loan 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 Loan 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 Loan Documents. If Administrative Agent requests instructions
from Lenders, with respect to any act or action in connection with any Loan
Document, then 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 such Lender, (ii) the effectiveness,
enforceability, genuineness, validity, or due execution of any Loan 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 Loan Document, or (v) observation of or compliance with
any of the terms, covenants, or conditions of any Loan 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 PRO RATA PART 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 LOAN DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE LOAN
DOCUMENTS IF ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR
SUCH AMOUNTS BY BORROWER. 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.

     12.4   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.

     12.5   Expenses.  Should Administrative Agent commence any proceeding or in
any way seek to enforce its Rights under the Loan Documents, each Lender, upon
demand therefor from time to time, shall contribute its share (based on its Pro
Rata Part) of the reasonable costs and/or expenses of any such 

                                       42
<PAGE>
 
enforcement, including, but not limited to, fees of receivers or trustees, court
costs, title company charges, filing and recording fees, appraisers' fees and
fees and expenses of attorneys to the extent not otherwise reimbursed by
Borrower. Without limiting the generality of the foregoing, each Lender shall
contribute its share (based on its Pro Rata Part) of all reasonable costs and
expenses incurred by Administrative Agent (including reasonable attorneys' fees
and expenses) if Administrative Agent employs counsel for advice or other
representation (whether or not any suit has been or shall be filed) with respect
to any of the Loan Documents, or to enforce any rights of Administrative Agent
or any of Borrower's or any other Company's obligations under any of the Loan
Documents, but not with respect to any dispute between Administrative Agent and
any other Lender(s). Any loss of principal and interest resulting from any
Default shall be shared by Lenders in accordance with their respective Pro Rata
Parts. It is understood and agreed that if Administrative Agent determines that
it is necessary to engage counsel for Lenders from and after the occurrence of a
Potential Default or Default, then said counsel shall be selected by
Administrative Agent and written notice of the same shall be delivered to
Lenders.

     12.6   Proportionate Absorption of Losses.  Except as otherwise provided in
the Loan Documents, nothing in the Loan 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 obligor on the Obligation having any credit,
allowance, setoff, defense, or counterclaim solely with respect to all or any
part of such Lender's Pro Rata Part of the Obligation).

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

     12.8   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 nor any other Person is responsible or liable
for, entitled to rely upon, or entitled to raise as a defense -- in any manner
whatsoever -- the failure of any Credit Party to comply with these provisions.

     12.9   Approval of Lenders.

     (a)    All communications from Administrative Agent to any Lender
requesting such Lender's determination, consent, approval, or disapproval (i)
shall be given in the form of a written notice to each Lender, (ii) shall be
accompanied by a description of the matter or thing as to which such
determination, approval, consent, or disapproval is requested, or shall advise
each Lender where such matter or thing may be inspected, or shall otherwise
describe the matter or issue to be resolved, (iii) shall include, if reasonably
requested by a Lender and to the extent not previously provided to such Lender,
written materials and a summary of all oral information provided to
Administrative Agent by Borrower in respect of the matter or issue to be
resolved, and (iv) shall include Administrative Agent's recommended course of
action or determination in respect thereof. Each Lender shall reply promptly,
but in any event (x) within thirty (30) days (or such lesser period as may be
required under the Loan Documents for Administrative Agent to respond) for those
matters requiring the consent by all Lenders, and (y) within fifteen (15)
Business Days (or such lesser period as may be required under the Loan Documents
for Administrative Agent to respond) for those matters requiring the consent by
the Required Lenders, in each instance, after receipt of the request therefor by
Administrative Agent (in either event, the "Lender Reply Period").

     (b)    Unless a Lender shall give written notice to Administrative Agent
that it objects to the recommendation or determination of Administrative Agent
(together with a written explanation of the

                                       43
<PAGE>
 
reasons behind such objection) within the Lender Reply Period, such Lender shall
be deemed to have approved of or consented to such recommendation or
determination.

     12.10  Default; Collateral.  Upon the occurrence and during the continuance
of a Default, the Credit Parties 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 the Credit Parties; and Administrative Agent
shall be entitled to refrain from taking any action (without incurring any
liability to any Person for so refraining) unless and until Administrative Agent
shall have received instructions from Required Lenders or Lenders, as the case
may be. All rights of action under this Agreement and under the Notes and all
rights to any collateral, if any, hereunder may be enforced by Administrative
Agent and any suit or proceeding instituted by Administrative Agent in
furtherance of such enforcement shall be brought in its respective name as
Administrative Agent without the necessity of joining as plaintiffs or
defendants any other Credit Party, and the recovery of any judgment shall be for
the benefit of the Credit Parties subject to the expenses of Administrative
Agent. In actions with respect to any property of any Company, Administrative
Agent is acting for the ratable benefit of each Credit Party.

SECTION 13   MISCELLANEOUS.
- ----------   ------------- 

     13.1   Headings.  The headings, captions, and arrangements used in any of
the Loan Documents are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify, or modify the terms of the Loan
Documents, nor affect the meaning thereof.

     13.2   Nonbusiness Days; Time.  Any payment or action that is due under any
Loan 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 Eurodollar
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.

     13.3   Communications.  Unless otherwise specifically provided, whenever
any Loan Document requires or permits any consent, approval, notice, request,
demand, or other communication from one party to another, communication must be
in writing (which may be by telex or telecopy) to be effective and shall be
deemed to have been given (a) if by telex, when transmitted to the appropriate
telex number and the appropriate answerback is received, (b) if by telecopy,
when transmitted to the appropriate telecopy number (and all communications sent
by telecopy must be confirmed promptly thereafter by telephone; but any
requirement in this parenthetical shall not affect the date when the telecopy
shall be deemed to have been delivered), (c) if by mail, on the fifth (5th)
Business Day after it is enclosed in an envelope and properly addressed,
stamped, sealed, certified mail, return receipt requested, and deposited in the
appropriate official postal service, or (d) if by any other means, when actually
delivered. Until changed by notice pursuant to this Agreement, the address (and
telecopy number) for each party to this Agreement is set forth on Schedule 1.

     13.4   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.

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

                                       44
<PAGE>
 
     13.6   Governing Law.  EXCEPT AS EXPRESSLY PROVIDED IN A LOAN DOCUMENT, THE
LAWS (OTHER THAN CONFLICT-OF-LAWS PROVISIONS) OF THE STATE OF TEXAS AND OF THE
UNITED STATES OF AMERICA GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN
DOCUMENTS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE
LOAN DOCUMENTS.

     13.7   Invalid Provisions.  Any provision in any Loan Document held to be
illegal, invalid or unenforceable is fully severable; the appropriate Loan
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. The Credit Parties and Borrower
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. However, if the provision held to be illegal, invalid or
unenforceable is a material part of this Agreement, such invalid, illegal or
unenforceable provision shall be, to the extent permitted by Law, replaced by a
clause or provision judicially construed and interpreted to be as similar in
substance and content to the original terms of such illegal, invalid or
unenforceable clause or provision as the context thereof would reasonably allow,
so that such clause or provision would thereafter be legal, valid and
enforceable.

     13.8   Venue; Service of Process; Jury Trial.  EACH PARTY TO ANY LOAN
DOCUMENT, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE CASE
OF BORROWER, FOR EACH OF THE OTHER COMPANIES), (a) IRREVOCABLY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS OF THE STATE OF TEXAS,
(b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY LITIGATION
ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE OBLIGATION
BROUGHT IN DISTRICT COURTS OF DALLAS OR HARRIS COUNTY, TEXAS, OR IN THE UNITED
STATES DISTRICT COURT FOR THE NORTHERN OR SOUTHERN DISTRICT OF TEXAS, DALLAS OR
HOUSTON DIVISION, (c) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT
IN ANY OF THE AFOREMENTIONED COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM,
(d) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THOSE COURTS IN
ANY LITIGATION BY THE MAILING OF COPIES THEREOF 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 SET FORTH IN THIS AGREEMENT, (e)
IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY LOAN
DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS OR THE
OBLIGATION MAY BE BROUGHT IN ONE OF THE AFOREMENTIONED COURTS, AND (f)
IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, ITS RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY
LOAN DOCUMENT. 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 contract claims,
tort claims, breach of duty claims, and all other common law and statutory
claims. Borrower (for itself and on behalf of each of the other Companies)
acknowledges that these waivers are a material inducement to each Credit Party's
agreement to enter into a business relationship, that each Credit Party has
already relied on these waivers in entering into this Agreement, and that each
Agent and each Lender will continue to rely on each of these waivers in related
future dealings. Borrower (for itself and on behalf of each other Company)
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

                                       45
<PAGE>
 
SECTION 13.8 ARE IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN
DOCUMENT. In the event of Litigation, this Agreement may be filed as a written
consent to a trial by the court.

     13.9   Amendments, Consents, Conflicts, and Waivers.

     (a)    Required Lenders.  Unless otherwise specifically provided the
provisions of this Agreement may be amended, modified, or waived only by an
instrument in writing executed by Borrower and the Required Lenders and
supplemented only by documents delivered or to be delivered in accordance with
the express terms of this Agreement.

     (b)    All Lenders.  Except as specifically otherwise provided in this
Section 13.9, any amendment to or consent or waiver under this Agreement or any
Loan Document that purports to accomplish any of the following must be by an
instrument in writing executed by Borrower and executed (or approved, as the
case may be) by Administrative Agent and each Lender (other than any Defaulting
Lender): (i) extends the Maturity Date (except as set forth in Section 3.18);
(ii) extends the due date or decreases the amount of any scheduled payment or
amortization of the Obligation beyond the date specified in the Loan Documents;
(iii) decreases any rate or amount of interest, fees, principal, or other sums
payable to any Credit Party under this Agreement (except such reductions as are
contemplated by this Agreement); (iv) changes the definition of "Historical
Value," "Implied Value," "Pool Consolidated Affiliates," "Pro Rata," "Pro Rata
Part," "Required Lenders," "Term Loan," or "Term Loans;" (v) amends or waives
the requirements of Section 7.15; (vi) increases any one or more Lender's Term
Loan; (vii) waives the requirement of, compliance with, amends, or fully or
partially releases any guaranty or any substantial part of any collateral, if
any (except as expressly permitted by the terms of the Loan Documents); (viii)
permits Borrower to assign any of its rights hereunder; or (ix) changes this
clause (b) or any other matter specifically requiring the consent of all Lenders
under this Agreement.

     (c)    Administrative Agent.  No amendment, modification, consent or waiver
which modifies the rights, duties, or obligations of any Agent shall be
effective without the consent of such Agent.

     (d)    Conflicts.  Any conflict or ambiguity between the terms and
provisions of this Agreement and terms and provisions in any other Loan Document
is controlled by the terms and provisions of this Agreement.

     (e)    Course of Dealing.  No course of dealing or any failure or delay by
any Credit Party or any of its respective Representatives with respect to
exercising any Right of such Credit Party under this Agreement operates as a
waiver thereof. Any waiver will be effective only in the specific instance and
for the specific purpose for which it is given.

     13.10  Multiple Counterparts.  Any Loan Document may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one agreement; but, in
making proof thereof, it shall not be necessary to produce or account for more
than one counterpart. Each Lender need not execute the same counterpart of this
Agreement so long as identical counterparts are executed by Borrower, each
Lender, and each Agent. This Agreement shall become effective when counterparts
of this Agreement have been executed and delivered to Administrative Agent by
each Lender, each Agent, and Borrower, or, in the case only of the Credit
Parties, when

                                       46
<PAGE>
 
Administrative Agent has received telecopied, telexed, or other evidence
satisfactory to it that each Credit Party has executed and is delivering to
Administrative Agent a counterpart of this Agreement.

     13.11  Successors and Assigns; Participations.

     (a)    Each Loan Document binds and inures to the benefit of the parties
thereto, any intended beneficiary thereof, and each of their respective
successors and permitted assigns. No Lender may, without the prior written
consent of Administrative Agent and, so long as no Default has occurred and is
continuing, Borrower, transfer, pledge, assign, sell any participation in, or
otherwise encumber its portion of the Obligation, except as specifically
permitted by this Section 13.11.

     (b)    Subject to the provisions of this Section 13.11 and in accordance
with applicable Law, any Lender may, in the ordinary course of its commercial
banking business, at any time sell to one or more Persons (each a "Participant")
participating interests in its portion of the Obligation; provided that each
such participation is not less than $10,000,000. The selling Lender shall remain
a "Lender" under this Agreement (and the Participant shall not constitute a
"Lender" under this Agreement) and its obligations under this Agreement shall
remain unchanged. The selling Lender shall remain solely responsible for the
performance of its obligations under the Loan Documents and shall remain the
holder of its share of the Principal Debt for all purposes under this Agreement.
Borrower and Administrative Agent shall continue to deal solely and directly
with the selling Lender in connection with such Lender's Rights and obligations
under the Loan Documents. Participants have no Rights under the Loan Documents,
other than certain voting Rights as provided below. Subject to the following,
each Lender may obtain (on behalf of its Participants) the benefits of Section 3
with respect to all participations in its part of the Obligation outstanding
from time to time so long as Borrower is not obligated to pay any amount in
excess of the amount that would be due to such Lender under Section 3 calculated
as though no participations have been made. No Lender may sell any participating
interest under which the Participant has any Rights to approve any amendment,
modification or waiver of any Loan Document, except to the extent the amendment,
modification or waiver extends the due date for payment of any principal,
interest or fees due under the Loan Documents, reduces the interest rate or the
amount of principal or fees applicable to the Obligation (except reductions
contemplated by this Agreement), or releases any guaranty or any substantial
part of the collateral, if any, for the Obligation. However, if a Participant is
entitled to the benefits of Section 3 or a Lender grants Rights to its
Participants to approve amendments to or waivers of the Loan Documents
respecting the matters described in the previous sentence, then such Lender must
include a voting mechanism in the relevant participation agreement whereby a
majority of its portion of the Obligation (whether held by it or participated)
shall control the vote for all of such Lender's portion of the Obligation.

     (c)    Subject to the provisions of this Section 13.11, any Lender may at
any time, in the ordinary course of its commercial banking business, (i) without
the consent of Borrower or Administrative Agent, assign all or any part of its
Rights and obligations under the Loan Documents to any of its Affiliates so long
as such Affiliate is an Eligible Institution (each a "Purchaser") and (ii) upon
the prior written consent of Administrative Agent, and so long as no Default has
occurred and is continuing, Borrower, such consents not to be unreasonably
withheld, assign to any other Eligible Institution (each of which is also a
"Purchaser") a proportionate part (not less than $15,000,000 and an integral
multiple of $1,000,000) of its Rights and obligations under the Loan Documents.
Notwithstanding the foregoing, each Agent shall, at all times prior to its
resignation or replacement as an Agent hereunder, retain a minimum Commitment of
$25,000,000, or if the Total Commitments have been terminated, then Notes having
outstanding Principal Debt of at least $25,000,000. In each case, the Purchaser
shall assume those Rights and obligations under an assignment agreement
substantially in the form of Exhibit E. Upon (i) delivery of an executed copy of

                                       47
<PAGE>
 
the assignment agreement to Borrower and Administrative Agent and (ii) payment
of a fee of $3,000 from the transferor to Administrative Agent, from and after
the assignment's effective date (which shall be after the date of delivery), the
Purchaser shall for all purposes be a Lender party to this Agreement and shall
have all the Rights and obligations of a Lender under this Agreement to the same
extent as if it were an original party to this Agreement with commitments as set
forth in the assignment agreement, and the transferor Lender shall be released
from its obligations under this Agreement to a corresponding extent, and, except
as provided in the following sentence, no further consent or action by Borrower,
Lenders, or any Agent shall be required. Upon the consummation of any transfer
to a Purchaser under this clause (c), the then-existing Schedule 1 shall
automatically be deemed to reflect the name, address, and Term Loan of such
Purchaser, Administrative Agent shall deliver to Borrower and Lenders an amended
Schedule 1 reflecting those changes, Borrower shall execute and deliver to each
of the transferor Lender and the Purchaser a Note in the face amount of its
respective Commitment following transfer, and, upon receipt of its new Note, the
transferor Lender shall return to Borrower the Note previously delivered to it
under this Agreement. A Purchaser is subject to all the provisions in this
Section as if it were a Lender signatory to this Agreement as of the date of
this Agreement.

     (d)    Any Lender may at any time, without the consent of Borrower or
Administrative Agent, assign all or any part of its Rights under the Loan
Documents to a Federal Reserve Bank without releasing the transferor Lender from
its obligations thereunder.

     (e)    Notwithstanding any contrary provision in this Agreement, a Lender
may not sell or participate any of its interests for a purchase price that,
directly or indirectly, reflects a discount from face value, without first
offering the sale or participation to the other Lenders on a Pro Rata basis
(which must be accepted or rejected within five (5) Business Days after the
offer).

     (f)    Borrower is 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 pursuant to this Section 13.11 is received by Borrower.

     13.12   Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances.  Borrower's obligations under the Loan Documents remain in full
force and effect until the Obligation is paid in full (except for provisions
under the Loan Documents which by their terms expressly survive payment of the
Obligation and termination of the Loan Documents). If at any time any payment of
the principal of or interest on any Note or any other amount payable by Borrower
or any other obligor on the Obligation under any Loan Document is rescinded or
must be restored or returned upon the insolvency, bankruptcy or reorganization
of Borrower or otherwise, the obligations of Borrower under the Loan Documents
with respect to that payment shall be reinstated as though the payment had been
due but not made at that time.

     13.13  Confidentiality.  Each Lender agrees to hold any confidential
information which (a) it has received prior to the Closing Date from Borrower
which is confidential and is not otherwise publicly available, and (b) it may
receive from Borrower pursuant to this Agreement after the Closing Date which
Borrower has marked "confidential" and is not otherwise publicly available, in
confidence, except (i) to other Lenders, (ii) to legal counsel, accountants, and
other professional advisors to such Lender who agree to be bound by the terms of
this Section, (iii) to regulatory officials, but only to the extent required by
such officials, (iv) upon prior notice to Borrower (which Lenders agree shall be
delivered as promptly as practicable), in connection with or response to
compliance with any Law or at the request of any Tribunal, but only to the
extent required by such Law or Tribunal, (v) upon prior notice to Borrower
(which Lenders agree shall be delivered as promptly as practicable), in
connection with any legal proceedings to which such

                                       48
<PAGE>
 
Lender is a party, but only to the extent required by such proceedings, and (vi)
to prospective Participants or Purchasers who agree to be bound by the terms of
this Section.

     13.14  Arbitration.  ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES
HERETO INCLUDING BUT NOT LIMITED TO THOSE ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY RELATED AGREEMENTS OR INSTRUMENTS, INCLUDING ANY CLAIM BASED ON
OR ARISING FROM AN ALLEGED TORT, SHALL BE DETERMINED BY BINDING ARBITRATION IN
ACCORDANCE WITH THE FEDERAL ARBITRATION ACT (OR IF NOT APPLICABLE, THE
APPLICABLE STATE LAW), THE RULES OF PRACTICE AND PROCEDURE FOR THE ARBITRATION
OF J.A.M.S./ENDISPUTE, INC. OR ANY SUCCESSOR THEREOF ("J.A.M.S."), AND THE
"SPECIAL RULES" SET FORTH BELOW. IN THE EVENT OF ANY INCONSISTENCY, THE SPECIAL
RULES SHALL CONTROL. JUDGMENT UPON ANY ARBITRATION AWARD MAY BE ENTERED IN ANY
COURT HAVING JURISDICTION. ANY PARTY TO THIS AGREEMENT MAY BRING AN ACTION,
INCLUDING A SUMMARY OR EXPEDITED PROCEEDING, TO COMPEL ARBITRATION OF ANY
CONTROVERSY OR CLAIM TO WHICH THIS AGREEMENT APPLIES IN ANY COURT HAVING
JURISDICTION OVER SUCH ACTION.

     (a)    SPECIAL RULES.  THE ARBITRATION SHALL BE CONDUCTED IN DALLAS, TEXAS
AND ADMINISTERED BY J.A.M.S. WHO WILL APPOINT AN ARBITRATOR; IF J.A.M.S. IS
UNABLE OR LEGALLY PRECLUDED FROM ADMINISTERING THE ARBITRATION, THEN THE
AMERICAN ARBITRATION ASSOCIATION WILL SERVE. ALL ARBITRATION HEARINGS WILL BE
COMMENCED WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION; FURTHER, THE ARBITRATOR
SHALL ONLY, UPON A SHOWING OF CAUSE, BE PERMITTED TO EXTEND THE COMMENCEMENT OF
SUCH HEARING FOR UP TO AN ADDITIONAL 60 DAYS.

     (b)    RESERVATION OF RIGHTS.  NOTHING IN THIS AGREEMENT SHALL BE DEEMED TO
(i) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF LIMITATION
OR REPOSE AND ANY WAIVERS CONTAINED IN THIS AGREEMENT; OR (ii) BE A WAIVER BY
LENDERS OF THE PROTECTION AFFORDED TO THEM BY 12 U.S.C. (S) 91 OR ANY
SUBSTANTIALLY EQUIVALENT STATE LAW; OR (iii) LIMIT THE RIGHT OF THE CREDIT
PARTIES (A) TO EXERCISE SELF HELP REMEDIES SUCH AS (BUT NOT LIMITED TO) SET-OFF,
OR (B) TO FORECLOSE AGAINST ANY REAL OR PERSONAL PROPERTY COLLATERAL, OR (C) TO
OBTAIN FROM A COURT PROVISIONAL OR ANCILLARY REMEDIES SUCH AS (BUT NOT LIMITED
TO) INJUNCTIVE RELIEF OR THE APPOINTMENT OF A RECEIVER. THE CREDIT PARTIES MAY
EXERCISE SUCH SELF HELP RIGHTS, FORECLOSE UPON SUCH PROPERTY, OR OBTAIN SUCH
PROVISIONAL OR ANCILLARY REMEDIES BEFORE, DURING OR AFTER THE PENDENCY OF ANY
ARBITRATION PROCEEDING BROUGHT PURSUANT TO THIS AGREEMENT. AT ADMINISTRATIVE
AGENT'S AND LENDERS' OPTION, FORECLOSURE UNDER A DEED OF TRUST OR MORTGAGE MAY
BE ACCOMPLISHED BY ANY OF THE FOLLOWING: THE EXERCISE OF A POWER OF SALE UNDER
THE DEED OF TRUST OR MORTGAGE, OR BY JUDICIAL SALE UNDER THE DEED OF TRUST OR
MORTGAGE, OR BY JUDICIAL FORECLOSURE. NEITHER THIS EXERCISE OF SELF HELP
REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN ACTION FOR FORECLOSURE OR
PROVISIONAL OR ANCILLARY REMEDIES SHALL CONSTITUTE A WAIVER OF THE RIGHT OF ANY
PARTY, INCLUDING THE CLAIMANT IN ANY SUCH ACTION, TO ARBITRATE THE MERITS OF THE
CONTROVERSY OR CLAIM OCCASIONING RESORT TO SUCH REMEDIES.

                                       49
<PAGE>
 
     13.15  Limitation of Liability of Trustees, Shareholders and Officers of
Borrower.  ANY OBLIGATION OR LIABILITY WHATSOEVER OF BORROWER WHICH MAY ARISE AT
ANY TIME UNDER THIS AGREEMENT OR ANY OBLIGATION OR LIABILITY WHICH MAY BE
INCURRED BY BORROWER PURSUANT TO ANY OTHER INSTRUMENT, TRANSACTION, OR
UNDERTAKING CONTEMPLATED HEREBY SHALL BE SATISFIED OUT OF BORROWER'S ASSETS
ONLY. NO SUCH OBLIGATION OR LIABILITY SHALL BE PERSONALLY BINDING UPON, NOR
SHALL RESORT FOR THE ENFORCEMENT THEREOF BE HAD TO, THE PROPERTY OF ANY OF
BORROWER'S TRUSTEES, SHAREHOLDERS, OFFICERS, EMPLOYEES OR AGENTS, REGARDLESS OF
WHETHER SUCH OBLIGATION OR LIABILITY IS IN THE NATURE OF CONTRACT, TORT, OR
OTHERWISE.
