Tax Return to be filed in a Subject Jurisdiction covering a Partial Tax Period
by or with respect to Company, Purchaser shall cause such Tax Return to be
prepared and shall cause to be included in such Tax Return all Tax Items
required to be included therein.  Purchaser shall determine (by an interim
closing of the books as of the Closing Date, except for ad valorem Taxes and
franchise Taxes based on capital which shall be prorated on a daily basis) the
portion, if any, of the Tax due by the Company with respect to the period
covered by such Tax Return to be filed in a Subject Jurisdiction which is
attributable to Company with respect to the Partial Tax Period after giving
effect to (i) any credits for the amount of such Tax, if any, paid on or prior
to the Closing Date (ii) any credit for any loss for prior periods and (ii) any

                                  ARTICLE XI.
                                INDEMNIFICATION

Any inaccuracy in any representation or warranty of Seller made in Article III
or in the certificate delivered by such Seller pursuant to Section 2.2(a); or

                          (ii)    Breaches of Covenants.  Any failure by Seller

                 (b)      Indemnification Obligation of Seller and Company.
Each Seller, severally, and, until the Closing, Company shall, joint and
severally, indemnify, defend, and hold Purchaser harmless from any and all
Claims directly or indirectly related or arising with respect to:

                          (i)     Breaches of Representations and Warranties.

                          (ii)    Breaches of Covenants.  Any failure to
perform or observe (A) in the case of any covenant or agreement of Company
which by its terms relates to the time period prior to the Closing, any
covenant or agreement of Company set forth in this


                                      29
<PAGE>   35
Agreement or in any agreement delivered pursuant to this Agreement, (B) any
covenant or agreement of Sellers set forth in this Agreement (other than the
covenant or agreement set forth in Section 6.7) or in any agreement delivered
pursuant to this Agreement.

         Section 11.2     Indemnification of Sellers.  Purchaser shall
indemnify, defend, and hold Sellers and, until the Closing, Company harmless
from any and all Claims directly or indirectly related or arising with respect
to:

                 (a)      Breaches of Representations and Warranties.  Any
inaccuracy in any representation or warranty of Purchaser made in Article V or
in the certificates delivered by Purchaser pursuant to Section 2.4(d) or
Section 9.2; or

                 (b)      Breaches of Covenants.  Any failure to perform or
observe any covenant or agreement of Purchaser set forth in this Agreement or
in any agreement delivered pursuant to this Agreement.

         Section 11.3     Indemnification Procedure.  The indemnification
obligations under this Agreement shall be subject to the following procedures:

                 (a)      Notice.  If a party entitled to be indemnified under
this Article XI (the "Indemnitee") shall incur any Claims or determine that it
is likely to incur any Claims, including without limitation claims by third
parties, and believes that it is entitled to be indemnified against such Claims
by another party hereunder (the "Indemnitor"), such Indemnitee shall deliver to
the Indemnitor a certificate (an "Indemnity Certificate") signed by the
Indemnitee which Indemnity Certificate shall:

                          (i)     state that the Indemnitee has paid or
properly accrued Claims, or anticipates that it will incur liability for Claims
for which such Indemnitee is entitled to indemnification pursuant to this
Agreement; and

                          (ii)    specify in reasonable detail each individual
item of Claims included in the amount so stated, the date such item was paid or
properly accrued, the basis for any anticipated liability, the nature of the
misrepresentation, breach of warranty or breach of covenant to which each such
item is related and the computation of the amount to which such Indemnitee
claims to be entitled.

                 (b)      Objections.  In case the Indemnitor shall object to
the indemnification of an Indemnitee in respect of any Claim or Claims
specified in any Indemnity Certificate, the Indemnitor shall within 15 days
after receipt by the Indemnitor of such Indemnity Certificate deliver to the
Indemnitee a written notice to such effect and the Indemnitor and the
Indemnitee shall, within the 30-day period beginning on the date of receipt by
the Indemnitee of such written objection, attempt in good faith to agree upon
the rights of the respective parties with respect to each of such Claims to
which the Indemnitor shall have so objected.  If the Indemnitee and the
Indemnitor shall succeed in reaching agreement on their respective rights with
respect to any of such Claims, the Indemnitee and the Indemnitor shall promptly
prepare and sign a memorandum setting



                                      30
<PAGE>   36
forth such agreement.  If Indemnitee and the Indemnitor are unable to agree as
to any particular item or items or amount or amounts, then Indemnitee and the
Indemnitor shall arbitrate such dispute pursuant to Article XII hereof.

                 (c)      Agreed Claims.  Claims specified in any Indemnity
Certificate to which an Indemnitor shall not object in writing, Claims covered
by a memorandum of agreement of the nature described in paragraph (b), Claims
the validity and amount of which have been the subject of arbitration as
described in paragraph (b) and Claims the validity and amount of which shall
have been the subject of a final judicial determination are hereinafter
referred to, collectively, as "Agreed Claims".

                 (d)      Defense of Claims.  Promptly after the assertion by
any third party of any Claim against any Indemnitee that, in the judgment of
such Indemnitee, may result in the incurrence by such Indemnitee of Claims for
which such Indemnitee would be entitled to indemnification pursuant to this
Agreement, such Indemnitee shall deliver to the Indemnitor a written notice
describing in reasonable detail such Claim and such Indemnitor may, at its
option, assume the defense of the Indemnitee against such Claim (including the
employment of counsel, who shall be reasonably satisfactory to such Indemnitee,
and the payment of expenses).  If 15 days after delivering notice of a Claim to
the Indemnitor or such shorter period necessary to prevent judgment by default
in favor of the Person asserting the Claim, the Indemnitor has not begun to
defend against such Claim, the Indemnitee shall have the right to defend or
settle such Claim on behalf of the Indemnitor.  Any Indemnitee shall have the
right to employ separate counsel in any such action or claim and to participate
in the defense thereto, but the fees and expenses of such counsel shall not be
at the expense of the Indemnitor unless (i) the Indemnitor shall have failed,
within the time period as provided in the preceding sentence, to assume the
defense of such claim, (ii) the employment of such counsel on behalf of the
Indemnitee has been specifically authorized by the Indemnitor, or (iii) the
named parties to any such action (including any impleaded parties) include both
such Indemnitee and the Indemnitor and such Indemnitee shall have been advised
in writing by its counsel that the Indemnitor possesses an actual or potential
conflict of interest with respect to the Indemnitee.  Under such circumstances,
the Indemnitor shall reimburse the Indemnitee for the Indemnitee's reasonable
attorneys' fees and expenses.  In addition, the Indemnitor shall reimburse the
Indemnitee for the Indemnitee's reasonable attorneys' fees and expenses
incurred during the period when the Indemnitor did not defend against the Claim
and in connection with Claims that Purchaser possesses the right to defend at
the expense of the Indemnitor as hereinabove provided.  Notwithstanding whether
the Claim involves a purported breach of the Indemnitor's representations and
warranties, the Indemnitor's obligation to reimburse such fees and expenses
shall be subject to the Indemnitor's Basket and shall be subject to the Maximum
Liability.  The Indemnitor shall make such reimbursement payments to the
Indemnitee upon the Indemnitee's submission of periodic invoices describing
such fees and expenses in reasonable detail.

                 (e)      Settlement of Claims.  The Indemnitor may settle any
Claim at its own expense, provided that the Indemnitor shall not settle any
Claim or consent to the entry of any judgment without the consent of the
Indemnitee if such settlement or



                                      31
<PAGE>   37
judgment (i)includes any admission of wrongdoing by the Indemnitee or any of
the Indemnitee's Representatives, (ii)includes any consent to any type of
injunctive relief affecting the Indemnitee or any of the Indemnitee's
Representatives, (iii)excludes an unconditional release by the Person asserting
the Claim of the Indemnitee and the Indemnitee's Representatives from all
liability with respect to such Claim, or (iv)requires the Indemnitee or any of
the Indemnitee's Representatives to undertake any obligations or incur any
costs that are not paid in advance by the Indemnitor.

                 (f)      Reimbursement.  If an Indemnitor undertakes the
defense of any Claim or settles any Claim and such Claim was not within the
scope of the Indemnitor's indemnification obligations under this Agreement, the
Indemnitee shall promptly reimburse the Indemnitor for all expenses with
respect to such defense or settlement, including the Indemnitor's reasonable
attorneys' fees and expenses.

                 (g)      Cooperation.  In connection with any indemnity
obligation, the Indemnitee shall cooperate with all reasonable requests of the
Indemnitor.

         Section 11.4     Meritless Third Party Claims.  If a third party makes
a Claim against the Indemnitee that ultimately proves to be meritless, the
Indemnitee may nevertheless require the Indemnitor to defend such Claim and
reimburse the Indemnitee for its reasonable attorneys' fees and expenses in
connection with such Claim as provided in Section 11.3(d), if such Claim was
within the scope of the Indemnitor's indemnification obligations under this
Agreement.

         Section 11.5     Assignment of Claims.  If any amounts for which the
Indemnitor is responsible are recoverable from a third party, including an
insurance carrier, the Indemnitee shall assign any rights that it may have to
recover such amounts to the Indemnitor.

         Section 11.6     Other Indemnitees.  Upon Purchaser's request, Sellers
shall indemnify any of Purchaser's Representatives to the same extent as
Purchaser.  Conversely, upon the request of Sellers' Agent, Purchaser shall
indemnify any of Seller's Representatives to the same extent as such Seller.
No Representative of any Party, however, shall be a third party beneficiary of
the indemnification provisions set forth in this Agreement.  In addition, a
Party may release or waive any Claim to which such Party previously requested
another Party to indemnify such Party's Representatives, and such
Representatives shall have no recourse against the Party releasing or waiving
such Claim.  To the extent that a Party requests another Party to indemnify
such Party's Representatives, such Party shall cause its Representatives to
comply with the indemnification provisions and abide by the indemnification
limitations set forth in this Agreement.

         Section 11.7     Contribution.  If the indemnity obligations provided
for in this Agreement are held unenforceable in whole or in part for any
reason, each Party shall perform such indemnity obligations to the extent
enforceable.  To the extent that such indemnity obligations are unenforceable,
the Party that would have been the Indemnitor


                                      32
<PAGE>   38
with respect to a Claim except for such unenforceability shall contribute to
such Claim in such proportion as appropriate to reflect the relative fault of
such Party as opposed to the relative fault of the Person who would have been
the Indemnitee, as well as any other relevant equitable considerations.

         Section 11.8     Right of Offset.  The Parties agree that the amount
of any Claim for damages or indemnification by Purchaser against Sellers shall
be offset by Purchaser solely against the Escrow Amount in accordance with the
terms of the Escrow Agreement.

         Section 11.9     Damages Without Indemnification.  A Party may assert
a Claim for damages against another Party for a breach of this Agreement even
though the Party seeking such damages has not incurred a liability of a fixed
amount or made a payment to another Person.

         Section 11.10    Basket.  The Parties acknowledge that all the
representations and warranties set forth in this Agreement are without
qualification as to materiality and that the provisions of this Section
regarding the Basket are intended to serve as the exclusive standard of
materiality for purposes of this Agreement.  No Party shall be liable for any
Claim for damages or indemnification with respect to a breach of such Party's
representations and warranties under this Agreement until the aggregate amount
of such Claims for damages and indemnification for which such Party would
otherwise be responsible concerning breaches of its representations and
warranties exceeds $50,000 (as the case may be, the "BASKET"), subject to
Section 11.12.  If the aggregate amount of such Claims for which a Party is
responsible exceeds the Basket, such Party shall then be responsible for all of
such Claims subject only to the Maximum Liability.

         Section 11.11    Maximum Liability.  Purchaser shall not be liable for
any Claim for damages or indemnification with respect to a breach of
Purchaser's representations, warranties or covenants under this Agreement to
the extent that the aggregate amount of such Claims exceeds the Purchase Price.
No Seller shall be liable for any Claim for damages or indemnification with
respect to a breach of representations, warranties or covenants under this
Agreement to the extent that the aggregate amount of such Claims exceeds the
Escrow Amount (such amounts are referred to as such Party's "MAXIMUM
LIABILITY"), subject to Section 11.12.  Any Claims for which a Party is not
held responsible because of the application of such Party's Basket shall not be
counted toward determining such Party's Maximum Liability.

         Section 11.12    Liabilities for Special Indemnities and Breaches of
Covenants.  Sellers Basket and Maximum Liability shall be inapplicable with
respect to any Claim for damages or indemnification concerning Sellers breach
of any representation and warranty set forth in Sections 3.1 or 4.5.  Sellers
Basket and Maximum Liability shall be inapplicable with respect to any Claim
for damages or indemnification concerning Sellers breach of any of its
covenants under Section 6.7 of this Agreement.

         Section 11.13    INTENTIONALLY OMITTED.



                                      33
<PAGE>   39
         Section 11.14    Interest.  A Party shall pay interest computed at the
rate earned on the Escrow Amount on (a) any Claim for damages with respect to
such Party's breach of this Agreement from the date of the breach or if later,
the date of any payment arising from the breach, through the date that the
Party pays such damages, and (b) any Claim for indemnification under this
Agreement for which such Party is the Indemnitor from the date of the
Indemnitee's indemnifiable out-of-pocket expenditure through the date that the
Party pays such Claim.

         Section 11.15    Notice of Breach.  If before the Closing a Party
notifies another Party of its breach of this Agreement, such notification shall
neither prevent such other Party from seeking damages for such breach nor
decrease or mitigate such damages if such other Party still closes the
transactions contemplated by this Agreement.

         Section 11.16    Discovery of Breach.  If before the Closing a Party
discovers that another Party has breached this Agreement, such discovery shall
neither prevent such Party from seeking damages for such breach nor decrease or
mitigate such damages if such Party still closes the transactions contemplated
by this Agreement.

         Section 11.17    Survival of Terms.  The agreements, covenants,
indemnity obligations, representations and warranties, and other terms of this
Agreement, Purchaser's closing certificate, each Seller's closing certificate,
Company's closing certificate and any other documents contemplated under this
Agreement shall survive the Closing and any investigation or notice by any
Party, provided that the representations, warranties and covenants of each
Party under this Agreement shall expire at 5:00 p.m. Fort Worth, Texas time on
the day immediately following the first anniversary of the Closing Date.
Notwithstanding the expiration of each Party's representations, warranties and
covenants described above, the representations, warranties and covenants set
forth in Article III, Section 4.5 (Capitalization) and Section 6.7, shall
survive for the period of the applicable statute of limitations.  A Party shall
not be responsible with respect to any Claim for damages or indemnification
with respect to any inaccuracy in any of such Party's representations or
warranties or breach of such Party's covenants unless such Party receives
notice of the Claim with respect to such inaccuracy or breach before such
representation, warranty or covenant expires.  With respect to any such Claim
received before the expiration of a particular representation, warranty or
covenant, the Party responsible for such representation, warranty or covenant
shall remain responsible for any damage or indemnification amounts claimed
notwithstanding the subsequent expiration of such representation, warranty or
covenant, provided that arbitration proceedings with respect to such Claim are
filed prior to the first anniversary of the last day on which the Indemnitor
must receive such notice, unless the Claim is otherwise resolved prior thereto.

         Section 11.18    Negligence and Strict Liability.  THE PROVISIONS OF
THIS AGREEMENT CONCERNING CLAIMS FOR DAMAGES AND INDEMNIFICATION SHALL APPLY
WHETHER OR NOT THE PARTY OR OTHER PERSON CLAIMING SUCH DAMAGES OR
INDEMNIFICATION WAS NEGLIGENT, GROSSLY NEGLIGENT, OR STRICTLY LIABLE IN
CONNECTION WITH THE EVENTS GIVING RISE TO SUCH CLAIM.



                                      34
<PAGE>   40
         Section 11.19    Sellers Remedies.  Any Claims by Sellers for
indemnification hereunder shall be made solely by the Sellers' Agent on behalf
of Sellers.  The liability of Purchaser for all indemnification claims made in
connection with this Agreement shall be satisfied solely by payment to the
Sellers.  To the extent that all or any portion of the Escrow Amount becomes
payable to the Sellers, such payment shall be made by the Escrow Agent to the
Sellers in accordance with the instructions of the Sellers' Agent.  Purchaser
shall not be responsible in any manner whatsoever for (i) any failure or
inability of the Sellers' Agent or the Escrow Agent to honor any provisions of
this Agreement, the Sellers' Agent Agreement or the Escrow Agreement, (ii) any
instructions given by the Sellers' Agent to the Escrow Agent or failure to give
such instructions by the Sellers' Agent, (iii) the investment of funds held by
the Sellers' Agent or the Escrow Agent or (iv) the amount or timing of the
disbursement of funds by the Sellers' Agent or the Escrow Agent.

                                  ARTICLE XII.
                       ARBITRATION AND EQUITABLE REMEDIES

         Section 12.1     Settlement Meeting.  The Parties shall attempt in
good faith to resolve promptly through negotiations any Claim or dispute under
this Agreement.  If any such Claim or dispute should arise, the Parties shall
meet at least once to attempt to resolve the matter (the "SETTLEMENT MEETING").
Any Party may request the other Parties to attend a Settlement Meeting at a
mutually agreed time and place within ten days after delivery of a notice of a
Claim or dispute.  The occurrence of a Settlement Meeting with respect to a
Claim or dispute shall be a condition precedent to seeking any arbitration or
judicial remedy, provided that if a Party refuses to attend a Settlement
Meeting the other Parties may proceed to seek such remedy.

         Section 12.2     Arbitration Proceedings.  If the Parties have not
resolved a monetary Claim or dispute at the Settlement Meeting any Party may
submit the matter to arbitration.  A panel of three arbitrators shall conduct
the arbitration proceedings in accordance with the Commercial Arbitration Rules
of the American Arbitration Association (the "ARBITRATION RULES").  The
decision of a majority of the panel shall be the decision of the arbitrators.

                 (a)      Arbitration Notice.  To submit a monetary Claim or
dispute to arbitration, a Party shall furnish the other Parties and the
American Arbitration Association with a notice (the "ARBITRATION NOTICE")
containing (i)the name and address of such Party, (ii)the nature of the Claim
or dispute in reasonable detail, (iii)the Party's intent to commence
arbitration proceedings under this Agreement, and (iv)the other information
required under the Federal Arbitration Act and the Arbitration Rules.

                 (b)      Selection of Arbitrators.  Within ten days after

select the third arbitrator from such list.  If the first two arbitrators
cannot select a third arbitrator within such ten day period, the American
Arbitration Association shall select such third arbitrator from the list.  Each
arbitrator shall be an individual not subject to disqualification under Rule
No. 19 of the Arbitration Rules with experience in settling comparable disputes
involving mergers and acquisitions.

                 (c)      Arbitration Final.  The arbitration of the matters in
controversy and the determination of any amount of damages or indemnification
shall be final and binding upon the Parties to the maximum extent permitted by
Law, provided that any Party may seek any equitable remedy available under Law
as provided in this Agreement.  This agreement to arbitrate is irrevocable.

         Section 12.3     Place of Arbitration.  Any arbitration proceedings
shall be conducted in Fort Worth, Texas or Dallas, Texas, or at such other
location as the Parties may agree.  The arbitrators shall hold the arbitration
proceedings within 60 days after the selection of the third arbitrator.

         Section 12.4     Discovery.  During the period beginning with the
selection of the third arbitrator and ending upon the conclusion of the
arbitration proceedings, the arbitrators shall have the authority to permit the
Parties to conduct such discovery as the arbitrators consider appropriate.

         Section 12.5     Equitable Remedies.  Notwithstanding anything else in
this Agreement to the contrary, after the Settlement Meeting a Party shall be
entitled to seek any equitable remedies available under Law, including an
injunction prohibiting a breach of the provisions of Section 6.7 or an Order
requiring a Seller to perform this Agreement.  Any such equitable remedies
shall be in addition to any damages or indemnification rights that such Party
may assert in an arbitration proceeding.

         Section 12.6     Exclusive Jurisdiction.  The Parties agree that any
claim for equitable relief relating to this Agreement shall be instituted in a
federal or state court sitting in Fort Worth, Texas or Dallas, Texas, which
courts and their respective appellate courts shall be the exclusive venue for
any such claim.  Each Party waives any objection that it may have to the laying
of such venue, and irrevocably submits to the jurisdiction of any such court
with respect to any such claim.  Any service of process and other notice in any
such case shall be effective against a Party when transmitted in accordance
with Section 13.9, provided that a Party also may serve process in any manner
permitted by Law.

judgment on such arbitration award upon application of a Party.

receive as part of any award or judgment

<PAGE>   42
reimbursement of such Party's reasonable attorneys' fees and expenses to the
extent that the arbitrators or court considers appropriate.  Notwithstanding
whether the arbitration or court proceedings involved a purported breach of a
Party's representations and warranties, the portion of any award or judgment
reimbursing the prevailing Party's attorneys' fees and expenses shall not be
subject to the other Parties' Basket or Maximum Liability.

         Section 12.9     Cost of the Arbitration.  The arbitrators shall
assess the costs of the arbitration proceedings, including their fees, to the
Parties in such proportions as the arbitrators consider reasonable under the
circumstances.

         Section 12.10    Exclusivity of Remedies.  To the extent permitted by
Law, the arbitration and judicial remedies set forth in this Article shall be
the exclusive remedies available to the Parties with respect to any dispute
under this Agreement or Claim for damages or indemnification under this
Agreement.

                                 ARTICLE XIII.
                                 MISCELLANEOUS

         Section 13.1     Amendment.  No amendment of this Agreement shall be

prior to the Closing) and Sellers' Agent.

         Section 13.2     Counterparts.  This Agreement may be executed in any
number of counterparts, each of which shall be deemed to be an original
agreement, but all of which shall constitute one and the same agreement.  Any
Party may execute and deliver this Agreement by an executed signature page
transmitted by a facsimile machine.  If a Party transmits its signature page by
a facsimile machine, such Party shall promptly thereafter deliver an originally

deliver such an originally executed signature page shall not affect the
validity, legality, or enforceability of this Agreement.

         Section 13.3     Entire Agreement.  This Agreement constitutes the
entire agreement and understanding between the Parties and supersedes all prior
agreements and understandings, both written and oral, with respect to the
subject matter of this Agreement.

         Section 13.4     Expenses.  Each Party shall bear its own expenses
with respect to the negotiation and preparation of this Agreement and the
Closing, including any fees and expenses of its Representatives, provided that
if a Party terminates this Agreement because of another Party's breach of this
Agreement, the non-breaching Party shall be entitled to seek reimbursement of
its expenses as part of its damages with respect to such breach to the extent
permitted by Section 10.2(b).  The amount, if any, by which the aggregate
amount of expenses of whatever kind and nature, including without limitation,
legal fees, accounting fees and any other brokerage or other fees

"SELLER EXPENSES."  Not less than one business day prior to the Closing Date,
the Company shall provide written

<PAGE>   43
notice (the "EXPENSE NOTICE") to Purchaser of the amount of all Transaction

paid, incurred or expected to be incurred by the Company as of the Closing
Date.  The amount of Seller Expenses set forth in the Expense Notice shall be
deducted from the Purchase Price and the Closing Cash Payment as provided in
Sections 1.2 and 1.3 hereof as an offset against Seller Expenses paid or
payable by the Company.  The Purchaser shall be reimbursed from the Escrow
Amount for any additional Seller Expenses not deducted from the Closing Cash
Payment.  All expenses of the Company incurred in connection with the
consummation of this Agreement incurred after the Closing Date and the fees and
expenses of the Sellers' Agent shall be paid by the Sellers.  The fees and
expenses of the Escrow Agent will be paid as set forth in the Escrow Agreement.

         Section 13.5     Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY
THE LAWS OF THE STATE OF TEXAS, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE
GOVERN UNDER THE CONFLICTS OF LAWS PRINCIPLES OF SUCH STATE.

         Section 13.7     No Assignment.  No Party may assign its benefits or
delegate its duties under this Agreement without the prior consent of the other
Parties.  Any attempted assignment or delegation without such prior consent
shall be void.  Notwithstanding this prohibition against assignment and
delegation, Purchaser may assign its rights and delegate its duties under this
Agreement to a wholly-owned subsidiary of Purchaser without Sellers' consent.

all of the assets or equity of Purchaser without Sellers' consent, and any such
purchaser and any subsequent purchasers of all of the assets or equity of
Purchaser may similarly assign such rights.

         Section 13.10    Public Announcements.  The Parties shall agree on the
terms of any press releases or other public announcements related to this
Agreement, and shall consult with each other before issuing any press releases
or other public announcements related to this Agreement; provided, however,
that any Party may make a public disclosure if in the opinion of such party's
counsel it is required by Law or the rules of the Nasdaq National Market to
make such disclosure.  The parties agree, to the extent practicable, to consult
with each other regarding any such public announcement in advance thereof.

         Section 13.11    Representation by Legal Counsel.  Each Party is a
sophisticated Person that was advised by experienced legal counsel and other
advisors in the negotiation and preparation of this Agreement.

         Section 13.12    Schedules.  All references in this Agreement to
schedules shall mean the schedules identified in this Agreement, which are
incorporated into this Agreement and shall be deemed a part of this Agreement
for all purposes.  Each Section of this Agreement that refers to a schedule
shall have a separate schedule.  In addition, any disclosure under a particular
section's schedule shall be made under the heading of any relevant subsection
of such section.  A disclosure of an item in a schedule for a particular
section or under a heading in a schedule corresponding to a particular
subsection shall not be a disclosure under any other section's schedule or any
other subsection, unless so noted specifically on such schedule. Sellers have
delivered to Purchaser a correct and complete copy of each document described
on each schedule to this Agreement and a correct and complete written
description of each unwritten arrangement or other item described on each such
schedule.

         Section 13.13    Severability.  Any provision of this Agreement that
is prohibited or unenforceable in any jurisdiction shall not invalidate the
remaining provisions of this Agreement or affect the validity or enforceability
of such provision in any other jurisdiction.  In addition, any such prohibited
or unenforceable provision shall be given effect to the extent possible in the
jurisdiction where such provision is prohibited or unenforceable.

         Section 13.14    Specific Performance.  Each Seller acknowledges that
the benefits that Purchaser will derive from the transactions contemplated by
this Agreement are unique and irreplaceable.  Accordingly, if such Seller
improperly abandons or terminates this Agreement, Purchaser would not have an
adequate remedy at law.  Purchaser therefore shall be entitled to a court order
requiring such Seller to perform this Agreement.

         Section 13.15    Successors.  This Agreement shall be binding upon and
shall inure to the benefit of each Party and its heirs, legal representatives,
permitted assigns, and successors, provided that this Section shall not permit
the assignment or other transfer of this Agreement, whether by operation of law
or otherwise, if such assignment of other transfer is not otherwise permitted
under this Agreement.

performance of this Agreement and all dates and periods specified in this
Agreement.

         Section 13.17    Waiver.  No provision of this Agreement shall be
considered waived unless such waiver is in writing and signed by the Party that
benefits from the enforcement of such provision.  No waiver of any provision in
this Agreement, however, shall be deemed a waiver of a subsequent breach of
such provision or a waiver of a similar provision.  In addition, a waiver of
any breach or a failure to enforce any term or condition of this Agreement
shall not in any way affect, limit, or waive a Party's rights under this
Agreement at any time to enforce strict compliance thereafter with every term
and condition of this Agreement.
