         As provided in Article 13 of the Merger Agreement, Maker shall have
the right to set-off and apply and reduce against its obligations hereunder
(first against interest and then against principal) any amounts owing by Payee
to Maker as a result of Payee's obligations with regard to Indemnification
Claims under the Merger Agreement.  Maker shall (except to the extent
prohibited by applicable law) give written notice to Payee (at the address set
forth above or at such other address provided to Maker in writing) following
any exercise of such set-off, including the amount owed Maker by Payee under
Article 13 of the Merger Agreement that Maker desires to set-off against
principal or interest owed by Maker hereunder (the "Proposed Set-Off Amount");
provided, however, the failure to give such notice shall in no manner affect
the right of Maker in respect to set-offs and corresponding applications of
funds.  During the period beginning when Maker notifies Payee of a set-off
claim for Indemnification Claims and the date the claim is resolved, interest
shall not accrue on the principal amount of this Note equal to the amount of
the Proposed Set-Off Amount; provided further, however, that if such claim is
ultimately resolved for an amount less than the Proposed Set-Off Amount (the
difference between such amount and the Proposed Set-Off Amount referred to
herein as the "Claim Amount Difference"), Maker shall pay to Payee, at the next
interest payment date, the amount of interest (to the extent not already paid)
not paid on the Claim Amount Difference prior to the ultimate resolution of
such claim.  In the event there be any outstanding Indemnification Claims  by
Maker that has not been resolved as of the Maturity Date of the principal
payment on this Note, Maker shall be entitled to defer payment of such
principal in than the amount that Maker believes Payee will be required to
indemnify Maker.  Any amounts deposited into an escrow account to governed by
the Escrow Agreement shall continue to be subject to Maker's right of set-off
described herein.

         Maker's obligation to pay principal and interest on this Notes
Receivable shall terminate immediately in the event that the Notes Receivable
(as defined in the Merger Agreement) are not repaid in full within five
business days of the date hereof.

         This Note shall be governed by and construed in accordance with the
internal laws of the State of Texas and applicable federal laws of the United
States of America.  This Note has been delivered and accepted and is payable at
Houston, Texas.  Notices to Maker hereunder shall be delivered to the notice
addresses for Maker set forth in the Merger Agreement or such other address
provided by Maker in writing to Payee.  This Note is not assignable by Payee
without the prior written consent of Maker, except that, if Payee is a trust or
estate, Payee may assign its rights hereunder to its beneficiaries provided
that such beneficiaries assume in writing (in a form reasonably satisfactory to
Maker) all of Payee's obligations under the Merger Agreement.

conditions of that certain Agreement and Plan of Merger dated July 31, 1998
(the "Purchase Agreement"), among Buyer, a wholly-owned subsidiary of Buyer,

The parties hereto, intending to be legally bound, hereby agree as follows:

1. ESTABLISHMENT OF ESCROW

(a) Pursuant to the terms of the Notes, Buyer is depositing with Escrow Agent,

investments, the "Escrow Fund"). Escrow Agent acknowledges receipt thereof.

(b) Escrow Agent hereby agrees to act as escrow agent and to hold, safeguard
and disburse the Escrow Fund pursuant to the terms and conditions hereof.

2. INVESTMENT OF FUNDS

The Escrow Fund shall be invested from time to time, to the extent possible, in

it receives joint written instructions of Buyer and Sellers or an order of a
court of competent jurisdiction as contemplated by Section 9;

Release Funds and then to other funds comprising part of the Escrow Fund.

5.DUTIES OF ESCROW AGENT

this Agreement.

(b)Escrow Agent shall not be liable, except for its own gross negligence or
willful misconduct, and, except with respect to claims based upon such gross

all losses, liabilities, claims, actions, damages and expenses, including
reasonable attorneys' fees and disbursements, arising out of and in connection
with this Agreement. Without limiting the

   10
foregoing, Escrow Agent shall in no event be liable in connection with its
investment or reinvestment of any cash held by it hereunder in good faith, in

in the investment or reinvestment of the Escrow Fund, or any loss of interest
incident to any such delays.

(c)Escrow Agent shall be entitled to rely upon any order, judgment,

signature believed by it to be genuine and may assume that the person
purporting to evidence receipt or advice or make any statement or execute any
document in connection with the provisions hereof has been duly authorized to
do so.  Escrow Agent may conclusively presume that the undersigned
representative of any party hereto that is an entity other than a natural
person has full power and authority to instruct Escrow Agent on behalf of that
party unless written notice to the contrary is delivered to Escrow Agent.

(d)Escrow Agent may act pursuant to the advice of counsel with respect to any
matter relating to this Agreement and shall not be liable for any action taken
or omitted by it in good faith in accordance with such advice.

(e)Escrow Agent does not have any interest in the Escrow Fund deposited
hereunder but is serving as escrow holder only and has only possession thereof.
Any payments of income from this Escrow Fund shall be subject to withholding
regulations then in force with respect to United States taxes. The parties
hereto will provide Escrow Agent with appropriate Internal Revenue Service

Agent.

(f)Escrow Agent makes no representation as to the validity, value, genuineness
or the collectability of any security or other document or instrument held by
or delivered to it.

(g)Escrow Agent shall not be called upon to advise any party as to the wisdom
in selling or retaining, or taking or refraining from any action with respect
to, any securities or other property deposited hereunder.

(h)Escrow Agent (and any successor Escrow Agent) may at any time resign as such
by delivering the Escrow Fund to any successor Escrow Agent jointly designated
by the other parties hereto in writing, or to any court of competent
jurisdiction, whereupon Escrow Agent shall be discharged of and from any and
all further obligations arising in connection with this Agreement. The
resignation of Escrow Agent will take effect on the earlier of (i) the
appointment of a successor (including a court of competent jurisdiction) and
(ii) the day that is 30 days after the date of delivery of Escrow Agent's
written notice of resignation to the other parties hereto. If at the end of
such 30-day period Escrow Agent has not received a designation of a successor
Escrow Agent, Escrow Agent's sole responsibility thereafter shall be to retain
and safeguard the Escrow Fund until receipt of a designation of successor

the event that Escrow Agent is in doubt as to what action it should take
hereunder, Escrow Agent shall be entitled to retain the Escrow Fund until
Escrow Agent shall have received (i) a final non-appealable order of a court of
competent jurisdiction directing delivery of the Escrow Fund or (ii) a written
agreement executed by the other parties hereto directing delivery of the Escrow
Fund, in which event Escrow Agent shall disburse the Escrow Fund in accordance

that may be given by a party will be applicable except in the specific instance
for which it is given; and (c) no notice to or demand on one party will be
deemed to be a waiver of any obligation of such party or of the right of the

demand as provided in this Agreement or the documents referred to in this
Agreement.
