            (a)   Letter of Credit Issuer agrees with each Revolver Lender that,

Outstanding Letter of Credit deemed sold to each Revolver Lender pursuant to
Section 2.1(b) of the Revolver Credit Agreement, and concurrently therewith, and

<PAGE>
of the Revolver Credit Agreement, each such Revolver Lender shall be released
and discharged from all obligations to reimburse the Letter of Credit Issuer as
provided in Section 2.1(b) of the Revolver Credit Agreement and in any letter of
credit application.

            (b)   Borrower and each Restricted Subsidiary (as defined in the
Revolver Credit Agreement) for which an Outstanding Letter of Credit has been
issued agree that their reimbursement obligations relative to the Outstanding
Letters of Credit will survive the assignment of the Revolver Credit Agreement
pursuant to this Agreement and will continue in full force and effect and be
governed by the letter of credit applications relating to the Outstanding
Letters of Credit (which letter of credit applications shall remain in effect
notwithstanding any references therein to the Revolver Credit Agreement) until
such reimbursement obligations are paid in full or otherwise discharged.

            (c)   As collateral security for the Letter of Credit Exposure in
connection with the Outstanding Letters of Credit, the Borrower hereby grants to
the Letter of Credit Issuer a continuing security interest in the Cash
Collateral and the Cash Collateral Account to secure any reimbursement
obligation of any one or more of the Borrower, Bluestem and the Quest Pledgors
arising by reason of the honoring by the Letter of Credit Issuer of any drawing
under any of the Outstanding Letters of Credit. The Borrower acknowledges that
the Letter of Credit Issuer has "control" (within the meaning of Section 9-104
of the Uniform Commercial Code in effect in the State of Texas) over the Cash
Collateral Account and agrees that the Letter of Credit Issuer may exercise and
enforce with respect to the Cash Collateral and the Cash Collateral Account, in
addition to all rights and remedies otherwise available to the Letter of Credit
Issuer, all rights and remedies available to a secured party under the Uniform
Commercial Code in effect in the State of Texas. The Borrower agrees that it
will, at any time and from time to time, promptly execute and deliver all
further instruments and documents and take all further action that may be
necessary or that the Letter of Credit Issuer may reasonably request in order
(i) to perfect and protect the security interests in the Cash Collateral and the
Cash Collateral Account created or purported to be created hereby and the first
priority of such security interests; (ii) to enable the Letter of Credit Issuer
to exercise and enforce its rights and remedies hereunder and under the Uniform
Commercial Code in effect in the State of Texas in respect of the Cash
Collateral and the Cash Collateral Account; or (iii) to otherwise effect the
purposes of this Agreement, including authorizing and filing such financing or
continuation statements, or amendments thereto, as may be necessary or that the
Letter of Credit Issuer may reasonably request in order to perfect and preserve
the security interests in the Cash Collateral and the Cash Collateral Account
created or purported to be created hereby.

            (d)   Upon presentation to the Letter of Credit Issuer by any
Beneficiary of a draft for payment under any Outstanding Letter of Credit, the
Letter of Credit Issuer shall, and shall be entitled to, apply, concurrently
with its payment made in honor of such draft, such amount of the Cash
Collateral, up to the full amount thereof, as is necessary to satisfy the
reimbursement obligation arising by reason of its honoring of such draft.

            (e)   The Borrower hereby covenants and agrees that it will obtain
the original Outstanding Letters of Credit from the appropriate beneficiaries,
and will return such Outstanding Letters of Credit to the Letter of Credit
Issuer within 45 days of the Assignment Date.

                                        7

<PAGE>

            (f)   The Letter of Credit Issuer hereby covenants and agrees that,
upon receipt and cancellation of all Outstanding Letters of Credit, it will
promptly return to the Borrower the Cash Collateral (less (i) any Outstanding LC
Fees (defined below) then owed as provided herein, (ii) any portion thereof
applied to satisfy draw requests under Outstanding Letters of Credit as provided
above, and (iii) any fees owing to the Letter of Credit Issuer hereunder) and
release its liens and security interests in the Cash Collateral and the Cash
Collateral Account.

            (g)   The Letter of Credit Issuer shall have no obligation to invest
or pay interest on the Cash Collateral.

            (h)   The Borrower hereby covenants and agrees that if the original
outstanding Letters of Credit are not returned to the Letter of Credit Issuer in
accordance with Section 8(e) it will pay a fee (an "Outstanding LC Fee") in an
amount equal to three-tenths of one percent (.30%) of the stated amounts of the
Outstanding Letters of Credit on each Quarterly Date (as defined in the Revolver
Credit Agreement).

      9.    Preservation of Liens and Security Interests. Except as expressly
set forth in Section 1 above with respect to the Released Collateral, nothing
contained herein shall be deemed to release, modify or impair the liens or
security interests in the Collateral comprising the Assigned Rights in any
respect, all of which shall continue to secure the obligations and indebtedness
under the New Credit Agreement, including, without limitation, the Obligations
(as defined in the New Credit Agreement) and all of which liens and security
interests are hereby ratified and confirmed. The Borrower hereby acknowledges
that the New Credit Agreement represents a renewal, extension, amendment and
modification of the Existing Debt, but does not represent a satisfaction or
novation thereof. Upon receipt of each original Revolver Note from the
applicable Revolver Lender, the New Agent shall mark such Revolver Note
"replaced" and promptly return such Revolver Note to the Borrower.

      10.   Miscellaneous. This Agreement shall be governed by and construed
under the laws of the State of Texas and shall be binding upon and inure to the
benefit of the parties hereto and their successors and assigns. This Agreement
may be executed in any number of counterparts, each of which shall be an
original, but all of which together shall constitute one instrument. Facsimiles
shall be effective as originals.

      11.   JURY WAIVER. THE PARTIES HERETO HEREBY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDINGS ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.
