provided that neither Party may invoke the use of the Auditor to determine the
final Adjustments or Prorations earlier than ninety (90) days after the Closing
Date. In the event that either Party invokes the use of the Auditor, there shall

Auditor. The Auditor shall be required to render a decision within fifteen (15)

conveyances of any kind that may be reasonably necessary or advisable to carry
out any of the provisions hereof, including without limitation, putting
Purchaser in possession and operating control of the Assets and the Systems.

12.     INDEMNIFICATION

        12.1 Survival. The representations, warranties, covenants and agreements
of the Parties contained in this Agreement (or in any document delivered in
connection herewith) shall be deemed to have been made on the date of this
Agreement and on the Closing Date, shall be deemed to be material and to have
been relied upon by the Parties notwithstanding any investigation made by the
Parties, shall survive the Closing Date and shall remain operative and in full
force and effect for a period of six (6) months following the Closing Date,
except for representations and warranties set forth in Sections 6.2, 6.11, 6.13
and 7.2 which shall survive until the applicable statute of limitations (the
applicable period of such survival being the "Indemnification Period").

        12.2 Sellers' and Centennial's Indemnity. During the Indemnification
Period (or thereafter, solely with respect to any claim for indemnification for
which Notice has been given prior to the expiration of the Indemnification
Period), Sellers and Centennial shall indemnify and hold harmless Purchaser, its
Affiliates and its representatives from and against any and all demands, losses,
Liabilities, Actions or causes of action, assessments, actual damages (but
excluding incidental or consequential damages), fines, Taxes, penalties,
reasonable costs and expenses (including, without limitation, interest,
reasonable expenses of investigation, reasonable fees and disbursements of
counsel, accountants and other experts) (collectively "Losses")

                                       20
<PAGE>   21

incurred or suffered by Purchaser, its Affiliates or its representatives,
arising out of, resulting from or relating to:

                      (a) Any breach of any of the representations or warranties
        made by Sellers in this Agreement;

                      (b) Any failure by Sellers to perform any of its covenants
        or agreements contained in this Agreement; or

                      (c) the Non-Assumed Liabilities;

provided, however, that no such indemnity shall be available to Purchaser for
Losses that relate to any circumstance, act or omission constituting a breach of
any representation or warranty by Sellers or failure of Sellers to comply with
any of their covenants or agreements hereunder if Purchaser had knowledge of
such circumstance, act, omission or failure at Closing, in which event Sellers
have no obligation with respect thereto.

        12.3 Purchaser's Indemnity. During the Indemnification Period (or
thereafter solely with respect to any claim for which indemnification has been
made prior to expiration of the Indemnification Period), Purchaser shall
indemnify and hold harmless Sellers, its Affiliates and its representatives from
and against any and all Losses incurred or suffered by Sellers, its Affiliates
or its representatives, arising out of, resulting from or relating to:

                      (a) Any breach of any of the representations or warranties
        made by Purchaser in this Agreement;

                      (b) Any failure by Purchaser to perform any of its
        covenants or agreements contained in this Agreement; or

                      (c) The Assumed Liabilities and any Liabilities arising
        from Purchaser's ownership and control of the Assets, the Business and
        the Systems after the Closing Date;

provided, however that no such indemnity shall be available to Sellers for
Losses that relate to any circumstance, act or omission constituting a breach of
any representation or warranty by Purchaser or failure of Purchaser to comply
with any of their covenants or agreements hereunder if Sellers had knowledge of
such circumstance, act, omission or failure at Closing, in which event Purchaser
have no obligation with respect thereto.

        Notwithstanding any provision contained in this Agreement to the
contrary, Sellers, Centennial or Purchaser shall not be liable under Section
12.2 or 12.3, respectively, until, and thereafter only to the extent, the
aggregate amount of its respective indemnification obligations pursuant to this
Section 12 exceeds on an aggregate basis $750,000, and then in such case Sellers
and Purchaser, as the case may be, will be liable only for the excess over
$750,000 up to the amount stated in the next succeeding sentence.
Notwithstanding anything contained in this


                                       21
<PAGE>   22

Agreement to the contrary, the maximum aggregate liability of Sellers under
Section 12.2 shall be $12,500,000 and the maximum aggregate liability of
Purchaser under Section 12.3 shall be $12,500,000.

        12.4 Procedure. In the event that any Party hereto shall sustain or
incur any Losses in respect of which indemnification may be sought by such party
pursuant to this Article 12, the party seeking such indemnification (the
"Indemnitee") shall assert a claim for indemnification by giving prompt written
notice thereof (the "Notice") which shall describe in reasonable detail the
facts and circumstances upon which the asserted claim for indemnification is
based, along with a copy of the claim or complaint, to the Party providing
indemnification (the "Indemnitor"). For purposes of this paragraph, any Notice
that is sent within fifteen (15) days of the date upon which the Indemnitee
actually learned of such Loss shall be deemed to have been "prompt notice;"
provided that failure of the Indemnitee to give the Indemnitor prompt notice as
provided herein shall not relieve the Indemnitor of any of its obligations
hereunder, except to the extent that the Indemnitor is materially prejudiced by
such failure.

               12.4.1 Upon the receipt of such Notice, the Indemnitor shall have
        the right to undertake (at its own expense), by counsel or
        representatives of its own choosing, the good faith defense, compromise
        or settlement to be undertaken on behalf of the Indemnitee and shall
        keep the Indemnitee reasonably informed with respect thereto, provided
        that the Indemnitor unconditionally agrees in writing to assume, as
        against the Indemnitee, all Losses relating to the Notice. Assumption of
        such Losses shall not be deemed an admission of liability on the part of
        the Indemnitor as against any such third party. If the Indemnitor elects
        to undertake such defense by its own counsel or representatives, the
        Indemnitor shall give notice to the Indemnitee within thirty (30) days
        of its receipt of the Notice. Notwithstanding the foregoing, the
        Indemnitor may not assume or control the defense if the named parties to
        the action giving rise to the Notice (including any impleaded parties)
        include both the Indemnitor and the Indemnitee and representation of
        both parties by the same counsel would be inappropriate (based on a
        written opinion of outside counsel) due to actual or potential differing
        interests between them, in which case the Indemnitee shall have the
        right to defend the action and to employ counsel reasonably approved by
        the Indemnitor, and, to the extent the matter is determined to be
        subject to indemnification hereunder, the Indemnitor shall reimburse the
        Indemnitee for all reasonable costs associated with such defense.

               12.4.2 The Indemnitee shall cooperate with the Indemnitor in such
        defense and provide the Indemnitor with all information and assistance
        reasonably necessary to permit the Indemnitor to settle and/or defend
        any such claim. Except as otherwise provided in the last sentence of
        Section 12.4.1, the Indemnitee may retain counsel (at the Indemnitee's
        expense) to monitor or participate in the defense of such claim, but the
        Indemnitor shall be entitled to control the defense, unless the
        Indemnitee unconditionally agrees in writing to relieve the Indemnitor
        from liability with respect to the particular matter. The Indemnitor
        shall have the right in good faith to settle or compromise any such
        claim, provided that at least ten (10) days prior notice of such
        settlement or compromise


                                       22
<PAGE>   23

        is given to the Indemnified Party. Notwithstanding the foregoing, in
        connection with any such settlement or compromise negotiated by the
        Indemnitor, no Indemnitee shall be required by an Indemnitor to (i)
        enter into any settlement that does not include as an unconditional term
        thereof the delivery by the claimant or plaintiff to the Indemnitee of a
        release from all liability in respect of such claim or litigation, or
        (ii) enter into any settlement that attributes by its terms any
        non-indemnified liability to the Indemnitee.

               12.4.3 If an Indemnitor fails, within thirty (30) days after the
        date of the Notice to give notice to the Indemnitee of said Indemnitor's
        election to assume the defense thereof, the Indemnitor shall be bound by
        any determination made in such action or any compromise or settlement
        thereof effected by the Indemnitee and shall reimburse the Indemnitee
        for all Losses (including reasonable attorney's fees) incurred by the
        Indemnitee; provided, however, that the Indemnitee shall keep the
        Indemnitor advised on a timely basis of significant developments with
        respect to such defense and permit the Indemnitor to participate, at its
        own election and expense, at any time, in the defense thereof.

        12.5 Indemnification Payments in Cash; Escrow Amount. All payments in
respect of any indemnification obligation shall be made in cash by wire transfer
of immediately available funds. The Escrow Amount shall be used to satisfy the
indemnification obligations, if any, of Sellers prior to any other funds being
required of Sellers to satisfy their indemnification obligations pursuant to
this Section 12.

        12.6 Investigations; Waivers. The survival periods and rights to
indemnification provided for in this Article 12 shall remain in effect
notwithstanding any investigation at any time by or on behalf of any Party or
any waiver by any Party of any condition to such Party's obligations to
consummate the transactions contemplated hereby.

13.     DEFAULT AND REMEDIES; RISK OF LOSS

        13.1 Opportunity to Cure. If any Party believes another to be in default
hereunder, such Party shall provide the other with prompt written notice
specifying in reasonable detail the nature of such default in which case such
party shall have 30 days to cure such default.

        13.2 Remedies. The Parties hereto shall have the right to pursue any
remedy that each may have at law or in equity. Without limiting the foregoing,
the Parties agree that irreparable damage would occur in the event that any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
Parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement and to enforce specifically the terms and provisions hereof in
any court of the United States or any State having jurisdiction, this being in
addition to any other remedy to which they are entitled at law or in equity.
Each Party agrees that it will not assert, as a defense against a claim for
specific performance, that the Party seeking specific performance has an
adequate remedy at law.


                                       23
<PAGE>   24

        13.3 Risk of Loss. The risk of any loss or damage to the Assets
resulting from fire, theft or any other casualty (except reasonable wear and
tear) shall be borne by Sellers at all times prior to the Closing. In the event
that any such loss or damage shall be sufficiently substantial so as to cause
any representation or warranty of Sellers not to be true and correct in all
material respects at the Closing Date, Sellers shall immediately notify
Purchaser in writing of the circumstances, and Purchaser, at any time within ten
days after receipt of such notice, may elect by written notice to Sellers either
to (a) waive such defect and proceed toward consummation of the transactions
contemplated by this Agreement in accordance with the terms hereof or (b)
terminate this Agreement. If Purchaser elects to so terminate this Agreement,
Purchaser and Sellers shall stand fully released and discharged of any and all
obligations hereunder.

14.     TERMINATION

        This Agreement may be terminated and the transactions contemplated
hereby abandoned at any time prior to the Closing Date, by written notice
promptly given to the other party hereto:

               (i)    by mutual consent of Sellers and Purchaser;

               (ii)   by Purchaser pursuant to Section 13.3; and

               (iii)  by Sellers if, at any time on or after the date 30 days
        after the satisfaction of all conditions to Closing set forth in Section
        9 (other than the conditions to be satisfied by deliveries to be made
        pursuant to Section 10.1), the Purchaser shall be unable or unwilling to
        consummate the Closing.

Neither Party may terminate this Agreement pursuant to this Section if such
Party is in material default hereunder. Nothing contained in this Section 14
shall relieve any Party hereto from liability for breach of this Agreement prior
to termination.

In the event this Agreement is terminated in accordance with the terms of
clauses (i) or (ii) of this Section 14, then the Parties shall promptly send a
notice to the Escrow Agent instructing the Escrow Agent to transfer the Escrow
Deposit, together with all interest accrued thereon, to Purchaser in accordance
with such notice. In the event this Agreement is terminated in accordance with
the terms of clause (iii) of this Section 14, then the Parties shall promptly
send a notice to the Escrow Agent instructing the Escrow Agent to transfer the
Escrow Deposit, together with all interest accrued thereon, to Sellers in
accordance with the terms of such notice. The disbursement of the Escrow Deposit
to any Party shall not preclude such Party from exercising any other rights or
remedies provided for in this Agreement or at law or equity in the event of a
breach by the other Party of its obligations to complete the Closing under this
Agreement.
