Net Working Capital (as defined below) of the Company and the Subsidiaries, and
shall have been prepared in accordance with generally accepted accounting
principles, applied consistently with the accounting methods and principles used
to prepare the financial statements of the Company referred to in Section 5.7.
Seller shall have the right to review all of Buyer's work papers and all
relevant records of Buyer and its accountants relating to the Closing Date
Balance Sheet. For purposes of this Agreement, Net Working Capital shall mean
the consolidated current assets of the Company, less its consolidated current
liabilities (other than indebtedness and other obligations which Seller is
obligated by this Agreement to repay on or prior to Closing), in each case as
determined in accordance with generally accepted accounting principles, applied
consistently with the accounting methods and principles used to prepare the
financial statements of the Company referred to in Section 5.7, as modified by
Section 7.1(vi) hereof, and further provided that the reserve for doubtful

                                      -5-
<PAGE>
 
accounts on the Closing Date Balance Sheet shall be established as disclosed in
Section 5.20 of the Disclosure Statement.

            (b) The Closing Date Balance Sheet delivered by Buyer to Seller
shall be deemed to be and shall be final, binding and conclusive on the parties
hereto, unless Seller disputes the Closing Date Balance Sheet in accordance with
this Section 3.3(b). Seller may dispute any amounts reflected on the Closing
Date Balance Sheet (any such disputed amounts, the "Disputed Matters");
provided, however, that Seller shall be entitled to dispute any such matter only
- --------  -------
if (1) Seller shall notify Buyer in writing of each Disputed Matter within
thirty (30) days of Seller's receipt of the Closing Date Balance Sheet and (2)
all such asserted disputes, if resolved in Seller's favor, would result in an
adjustment to the Closing Payment in excess of $50,000 (in which event the full
amount of the adjustment, as finally determined, shall be made as provided
below). Any Disputed Matters shall be subject to good faith negotiations between
the parties for up to fifteen (15) days prior to being referred to the
Independent Accounting Firm (as defined below). Any Disputed Matters not
resolved by such good faith negotiations shall be decided by an independent
accounting firm acceptable to both Seller and Buyer (the "Independent Accounting
Firm"). The costs and expenses of the Independent Accounting Firm shall be
shared equally by Seller and Buyer. The Independent Accounting Firm so chosen
shall consider only the Disputed Matters and Buyer and Seller shall use
reasonable efforts to cause the Independent Accounting Firm to render a final
decision on the Disputed Matters by delivering a written report to Buyer and
Seller no later than thirty (30) days after having received the assignment with
respect thereto. The decision of the Independent Accounting Firm with respect to
all Disputed Matters shall be based solely on whether the Closing Date Balance
Sheet was prepared in accordance with the requirements of this Agreement, shall
be final and binding upon the parties hereto and shall not be subject to
challenge in any court.

         Section 3.4.  Post-Closing Adjustment.
                       -----------------------

            (a) If the Net Working Capital as of the Closing Date as
conclusively determined as provided in Section 3.3 (such conclusive
determination is referred to herein as "Certified Net Working Capital"), is less
than $25,000, then Seller shall pay, or cause to be paid, to Buyer the amount of
such deficiency. If the Certified Net Working Capital is greater than $25,000,
then Buyer shall pay, or cause to be paid, to Seller the amount of such

                                      -6-
<PAGE>
 
excess. Any payment pursuant to this Section 3.4(a) shall be made within five
(5) business days following the conclusive determination of Net Working Capital
(such fifth business day, the "Due Date"). Any payment not made by the Due Date
therefor shall bear interest from the Due Date at the rate of ten percent
(10.0%) per annum.

            (b) Payments made pursuant to this Section 3.4 shall be made by wire
transfer of immediately available funds to an account designated by the party
receiving such payment.

         Section 3.5.  Landfill Gas Utilization Project.
                       --------------------------------

            (a) If, prior to October 31, 1998, Toro Energy, Inc. or any of its
affiliates shall have entered into an agreement satisfactory to Buyer for the
commercial utilization of certain gas generated at the Project (the "Gas
Contract"), then Buyer shall, during the first five years of the operation of
the Project, pay to Seller, in cash no less frequently than quarterly,
twenty-five percent (25.0%) of the Operating Revenue (as defined below) received
by PGL (under the Gas Contract) and DCTC Burney, Inc., (as a distribution on its
member interest in Pine Grove Development LLC ("PGD")) (such payments, the
"Landfill Gas Payments"). For the purposes of this Agreement, "Operating
Revenue" shall mean gross revenues less operating expenses, which shall be
negotiated in good faith by the parties prior to the Closing Date.

            (b) Prior to Closing, Seller shall use reasonable efforts to obtain
the consent of the other member of PGD to the transfer, to Buyer (or Buyer's
designee) of the 49% membership interest therein owned by an affiliate of
Seller, which consent shall also include an estoppel certificate, in form and
substance reasonably satisfactory to Buyer, with respect to the obligations of
PGL under that certain Gas Lease and Easement Agreement, dated December 29,
1995. Such estoppel shall acknowledge PGL's right to terminate such Gas Lease
and Easement Agreement at any time before a Gas Contract which is acceptable to
PGL is entered into. Provided that such consent and estoppel has been obtained,
Seller shall cause such interest to be assigned and transferred to Buyer at
Closing, free and clear of all Encumbrances other than those set forth in the
Membership Agreement of PGD. However, if such consent and estoppel is not so
obtained, Seller shall not be obligated to effect such transfer and Buyer shall
have no obligations pursuant to Section 3.5(a), however, Seller shall then
cause

                                      -7-
<PAGE>
 
DCTC Burney, Inc. to deliver to Buyer at Closing an estoppel certificate to the
same effect as referred to above.

           (a)   The Seller has delivered to Buyer (i) the unaudited
consolidated balance sheet of the Company and the Subsidiaries as at December
31, 1996 (the "Balance Sheet") and the consolidating balance sheets of the

related unaudited statements of income and cash flow for each of the fiscal

the unaudited consolidated balance sheet of the Company and the Subsidiaries as
at September 30, 1997 (the "Interim Balance Sheet"), and the consolidating
balance sheets of the Company and each Subsidiary as of such date, and the
related unaudited statements of income and cash flow for the nine (9) months
then ended (collectively, the "1997 Interim Statements"). Subject to the
disclosures made in Section 5.20 of the Disclosure Statement, the Historic
Financial Statements and the 1997 Interim Statements fairly present, in all
material respects, the consolidated financial condition, cash flow and results
of operations of the Company and the Subsidiaries as of the respective dates
thereof and for the periods therein referred to, all in accordance with United

in the case of the 1997 Interim Statements, Seller's reasonable estimates of
accruals and adjustments applied on a basis consistent with Seller's past
preparation of interim financial statements. The Balance Sheet and the Interim

equal to reasonably anticipated

                                      -13-

reflect all material liabilities of the Company and the Subsidiaries, whether
absolute, accrued or contingent, as of the respective dates thereof of the type
required to be reflected or disclosed in a balance sheet (or the notes thereto)
prepared in accordance with GAAP. Neither the Company nor any Subsidiary has any
material liabilities or obligations of a nature required to be reflected in a
balance sheet prepared in accordance with GAAP that are not reflected on the

GAAP) which have been incurred since the date thereof in the ordinary course of

services rendered in the ordinary course of business and to the knowledge of the
Company are not subject to any known defenses or rights of set-off. The reserve

Premises owned by it, including all real property permitted as a landfill under
the Solid Waste Management Act, under the permits set forth in Section 5.5(b)IA
(1 through 36) of the Disclosure Statement, insurable at regular rates by a
title insurance company authorized to do business in the Commonwealth of
Pennsylvania pursuant to the standard stipulations and conditions of ALTA Policy
of Owner's Title Insurance (10/17/92) (provided that no representation is made

owns all right, title and interest in all leasehold estates and other rights
purported to be granted to it by the leases and other agreements listed in
Section

                                      -14-

5.9 of the Disclosure Statement, in each case free and clear of any Encumbrances
except for (i) liens for current taxes, assessments and governmental charges and
levies which may be paid without penalty, interest or other additional charge,
(ii) such easements and restrictions, if any, as do not materially detract from
the value or marketability of the property subject thereto, (iii) any

Encumbrances which have been disclosed by a title insurance policy identified by
policy number on the Disclosure Statement and (v) Encumbrances on the Tax
Parcels identified in Section VII(A) of Section 5.9 of the Disclosure Statement,
as to which no representation is being made. To the knowledge of Seller, no
building or structure included in the Premises violates any restrictive covenant
or encroaches on any property owned by others. No condemnation proceeding is
pending or, to the knowledge of Seller, threatened, with respect to any of the
Premises. Seller has made available to Buyer true and complete copies of all
deeds and other instruments (as recorded) by which the Company and each
Subsidiary acquired the Premises. To the knowledge of Seller, except as set
forth in the Section 5.9 of the Disclosure Statement or in the leases and
agreements identified therein, there are no lease agreements, purchase
agreements, rights of first refusal, options or other agreements or commitments
in effect conveying to any person or entity any rights with respect to the
Premises.

     Section 5.10.  Personal Property.  The Company and each Subsidiary has
                    -----------------
good and marketable title to all of the personal property reflected on its books
and records as being owned by it, including, except as they have since been
affected by transactions in the ordinary course of business, the personal
property reflected as being owned in the Interim Balance Sheet, free and clear
of any Encumbrances, except such as are reflected in the Interim Balance Sheet

insurance contained in Section 5.13 of the Disclosure Statement identifies: (i)

                                 ARTICLE XIII.

                                   INDEMNITY

          Section 13.1.  Indemnity by Seller.
                         -------------------

          (a)  From and after the Closing, Seller shall indemnify and hold Buyer
harmless from and against any liabilities, obligations, losses, damages, costs,
charges or other expenses of every kind and character, including reasonable
attorneys' fees and litigation expenses (including costs of expert witnesses)
and disbursements (collectively, "Damages") arising after the Closing and
actually suffered by or incurred by Buyer to the extent arising

                                      -37-
<PAGE>
 
out of or as a result of (i) the inaccuracy of any representation or warranty or
the breach, nonfulfillment or nonperformance of any covenant or agreement of
Seller under this Agreement or any other Transaction Document; (ii) any and all
amounts which relate to liability for Taxes of the Company or any Subsidiary for
any period or periods ending on or before the Closing Date, excluding any Taxes
that are accrued and reflected as a liability on the Interim Balance Sheet or
the Closing Balance Sheet or (iii) action by the Pennsylvania Department of
Environmental Protection, Schuylkill County or Pine Grove Township for any
malodor from the Landfill which occurred prior to Closing. Notwithstanding the
foregoing, Seller shall not be required to indemnify or hold harmless Buyer with
respect to any loss incurred by Buyer unless and until the aggregate amount of
all Damages incurred by Buyer in respect of which Seller would be liable to
Buyer under this Section 13.1 exceeds $500,000 (in which case Seller shall be
responsible for all such Damages, subject to the terms of this Agreement), and
notwithstanding anything contained herein to the contrary, the aggregate amount
required to be paid by Seller pursuant to this Section 13.1 shall not exceed
seventy-five percent (75%) of the Closing Payment. Certain representations or
warranties of Seller contained herein are qualified by "materiality" (such as, a
representation that a certain condition or event has occurred or exists "in all
material respects"). For purposes of determining, pursuant to Section 13.1(a),
whether representations and warranties qualified by materiality are accurate or
inaccurate, such representation or warranty will be deemed correct if all
instances or circumstances of noncompliance, in the aggregate, result in Damages
of less than $50,000. For the sake of clarity, this interpretation of the phrase
"in all material respects" and of the word "material" shall not be used to
interpret or modify the parties' obligations under any provision hereof other
than as set forth in Section 13.1(a)(i), including without limitation the
parties' obligations under Sections 9.1 and 10.1 hereof.

          (b)  The indemnification provided for in Section 13.1 shall be limited
to claims asserted and claim notices delivered within eighteen (18) months from
and after the Closing Date; provided, however, that a claim that Seller has
                            --------  -------
breached its representations and warranties made in Sections 5.15 and 5.16
hereof may be made at any time before the expiration of the statute of
limitations that would be applicable to an action brought by the appropriate
taxing authority with respect to the matters forming the basis for such claim.

                                      -38-
<PAGE>
 
          (c)  The remedy provided by this Section 13.1, subject to the
limitations set forth in this Article XIII, shall be Buyer's sole and exclusive
remedy for the recovery of any damages, losses, deficiencies, liabilities, costs
and expenses resulting from, relating to or arising out of any (i)
misrepresentation or breach of warranty made by or on behalf of Seller in this
Agreement or in any certificate delivered by Seller pursuant hereto, (ii)
non-fulfillment of any agreement or covenant on the part of Seller or (iii) any
other aspect of any transaction contemplated by this Agreement.
     
          (d)  Notwithstanding any other provision hereof, Seller shall have no
liability in respect of any claim for indemnification under this Section 13.1:

                 (i)  if and to the extent that provision or reserve for or in
respect of the liability or other matter giving rise to such claim has been made
in the Interim Balance Sheet or the Closing Date Balance Sheet, and such
liability has been taken into account in calculating the Closing Adjustment
pursuant to Section 3.4 hereof;

                (ii)  if and to the extent that such claim arises as a result of
any change in legislation that takes effect retrospectively;

               (iii)  if and to the extent that such claim is caused by or
attributable to any voluntary act, omission, transaction or arrangement of
Buyer, the Company or any Subsidiary from and after the Closing (provided that,
for the sake of clarity, this provision shall not reduce Seller's obligations
pursuant to Section 13.1(a) hereof by reason of any breach of representation or
warranty by Seller); or

                (iv)  to the extent that Buyer, the Company or any Subsidiary is
insured against any loss or damage suffered by it arising out of such breach or
claim under the terms of any insurance policy.

          Section 13.2.  Indemnification by Buyer.  From and after the Closing,
                         ------------------------
Buyer shall indemnify and hold harmless Seller from and against any and all
Damages arising after the Closing and actually suffered or incurred by Seller
arising out of or as a result of (i) the inaccuracy of any representation or

     Section 13.3.  Procedure for Indemnification with Respect to Third Party
                    ---------------------------------------------------------
                    Claims.
                    ------

          (a)  If any third party shall notify a party to this Agreement (the
"Indemnified Party") with respect to any matter (a "Third Party Claim") that may
give rise to a claim for indemnification against the other party to this
Agreement (the "Indemnifying Party") under this Article XIII, then the
Indemnified Party shall promptly notify the Indemnifying Party thereof in
writing; provided, however, that subject to Section 13.1(b), no delay on the
part of the Indemnified Party in notifying the Indemnifying Party shall relieve
the Indemnifying Party from any obligation hereunder unless (and to the extent)
the Indemnifying Party is thereby prejudiced. Such notice shall state the amount
of the claim and the relevant details thereof.

          (b)  The Indemnifying Party will have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice
reasonably satisfactory to the Indemnified Party so long as (i) the Indemnifying
Party notifies the Indemnified Party in writing within ten days after the
Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party pursuant to the
provisions of Article XIII, as applicable, from and against all Damages incurred
by the Indemnified Party resulting from the Third Party Claim, (ii) the
Indemnifying Party provides the Indemnified Party with evidence reasonably
acceptable to the Indemnified Party that the Indemnifying Party has the
financial resources to defend against the Third Party Claim and fulfill its
indemnification obligations hereunder, and (iii) the Third Party Claim involves
only monetary damages and does not seek an injunction or equitable relief.

          (c)  So long as the Indemnifying Party is conducting the defense of
the Third Party Claim in accordance with Section 13.3(b) above, (i) the
Indemnified Party may retain separate co-counsel at its sole cost and expense
and participate

                                      -40-
<PAGE>
 
in (but not control) the defense of the Third Party Claim, (ii) the Indemnified
Party will not consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without the prior written consent of the
Indemnifying Party, and (iii) the Indemnifying Party will not consent to the
entry of any judgment or enter into any settlement with respect to the Third
Party Claim without the prior written consent of the Indemnified Party (which
will not be unreasonably withheld). In the case of (c)(ii) or (c)(iii) above,
any such consent to judgment or settlement shall include, as an unconditional
term thereof, the release of the Indemnifying Party from all liability in
connection therewith.

          (d)  If any condition set forth in Section 13.3(b) above is or becomes
unsatisfied or if the Indemnifying Party does not assume the defense of the
Third Party Claim pursuant to Section 13.3(b), (i) the Indemnified Party may
defend against, and consent to the entry of any judgment or enter into any
settlement with respect to, the Third Party Claim and any matter it may deem
appropriate and the Indemnified Party need not consult with, or obtain any
consent from, any Indemnifying Party in connection therewith, and (ii) the
Indemnifying Party will remain responsible for any Damages suffered by the
Indemnified Party to the extent provided in this Article XIII.

     Section 13.4.  Procedure for Non-Third Party Claims.  If Buyer or Seller
                    ------------------------------------
wishes to make a claim for indemnity under Section 13.1 or Section 13.2, as
applicable, and the claim does not arise out of a third party notification which
makes the provisions of Section 13.3 applicable, the party desiring
indemnification shall deliver to the party from which indemnification is sought
a written demand for indemnification ("Indemnification Demand"). The
Indemnification Demand shall state: (a) the amount of Damages which the
Indemnified Party has incurred or has suffered or is expected to incur or suffer
for which the Indemnified Party is entitled to indemnification pursuant to
Section 13.1 or Section 13.2, as applicable; and (b) the nature of the event or
occurrence which entitles the Indemnified Party to receive payment under Section
13.1 or Section 13.2, as applicable. If the Indemnifying Party wishes to object
to an Indemnification Demand, the Indemnifying Party must send written notice to
the Indemnified Party stating the objections and the grounds for the objections
("Indemnification Objection"). If no Indemnification Objection is sent within
thirty (30) days after the Indemnification Demand is sent, the Indemnifying
Party shall be deemed to have acknowledged

                                      -41-
<PAGE>
 
the correctness of the claim or claims specified in the Indemnification Demand
and shall pay the full amount claimed in the Indemnification Demand within
forty-five (45) days of the day the Indemnification Demand is dated.

     Section 13.5.  Special Tax Provisions.
                    ----------------------

          (a)  Seller shall include Pine Grove, Inc. in its consolidated federal
tax return and in any state or local tax return filed on a consolidated,
combined or unitary basis through the close of business on the Closing Date.

                 (i)   Seller and Buyer shall jointly make a timely election
under Section 338(h)(10) of the Internal Revenue Code of 1986 (and any
corresponding elections under state or local tax law) (collectively, a "Section
338(h)(10) Election") with respect to Company and the Subsidiaries.

                (ii)   Seller and Buyer shall (a) take, and cooperate with each
other to take, all actions necessary and appropriate (including filing such
forms, returns, elections, schedules and other documents as may be required) to
effect and preserve a timely Section 338(h)(10) Election in accordance with
Section 338 of the Code and the applicable regulations and from time to time
thereafter, and (b) Seller and Buyer shall report the sale of the Pine Grove,
Inc. Stock pursuant to this Agreement consistent with the Section 338(h)(10)
Election and shall take no position contrary thereto or inconsistent therewith
in any tax return, any discussion with or proceeding before any taxing
authority, or otherwise.

               (iii)   Allocations.  As soon as practicable after the date
                       -----------
hereof, but in no event later than 90 days prior to the date for filing of the
consolidated Delmarva Power & Light Co. return for 1997 (taking into account any
extensions), Buyer shall prepare for Seller's review a schedule setting forth
(a) the modified aggregate deemed sales price (the "MADSP") at which the Company
is deemed to have sold its assets for tax purposes as a result of the Section
338(h)(10) Election, (b) the adjusted grossed-up basis (the "AGUB") at which the
Company is deemed to have purchased its assets for tax purposes as a result of
such election, and (c) the allocations of MADSP and AGUB among the assets of the
Company (collectively, the "Proposed Initial Allocation"). The Proposed Initial
Allocation shall be determined in accordance with Section 338 of the Code and
the applicable

                                      -42-
<PAGE>
 
regulations thereunder, in a manner consistent with the allocation set forth on
Schedule 13.5 hereto. Unless Seller shall have objected in writing to the
Proposed Initial Allocation within 30 days of the receipt thereof, Seller will
be deemed to have agreed to the Proposed Initial Allocation, which shall become
the Initial Allocation. The Initial Allocation shall be set forth on a statement
(the "Initial Allocation Statement") signed by the president or any vice
president of Buyer and Seller. If any increase or decrease in MADSP and/or AGUB
occurs, the amount of such increase or decrease and the allocation thereof among
the assets of the Company (collectively, the "Adjustment Allocation") shall be
set forth on a statement (the "Adjustment Allocation Statement") prepared by
Buyer and delivered to Seller. The Adjustment Allocation Statement shall be
subject to the consent of Seller. Buyer and Seller will, to the maximum extent
permitted under applicable law, (a) file, or cause to be filed, all Tax Returns
in a manner consistent with the Initial Allocation and any Adjustment
Allocations and (b) not take any action inconsistent therewith.

                (iv)   Dispute Resolution.  Any dispute regarding the Proposed
                       ------------------
Initial Allocation or any Adjustment Allocation shall be submitted for
resolution to independent accountants of nationally recognized standing
reasonably satisfactory to Buyer and Seller (the "Tax Dispute Accountants"). The
decision of the Tax Dispute Accountants shall be final, conclusive and binding
on the parties. The fees and expenses of the Tax Dispute Accountants in
resolving a dispute will be borne equally by Buyer and Seller except that the
Tax Dispute Accountants may, if justice requires, allocate such expenses and
fees in any other manner they may determine between the Buyer, on the one hand,
and Seller, on the other.

          (b)  Buyer shall cause the Company to timely prepare and file any
required Tax Returns of the Company which are due after the Closing Date and
which include any period prior to the Closing Date. At least twenty business
days prior to the filing of the Tax Returns that the Company is required to file
pursuant to this Section 13.5, Buyer shall provide Seller with copies of such
Tax Returns for Seller's approval, which approval shall not be unreasonably
withheld. If Buyer fails to comply with any reasonable request of Seller made in
relation to and before filing of such Tax Return, then Seller shall cease to
have any liability to make any payment in respect of any liability for Taxes
resulting from the failure or refusal of Buyer to comply with such request.

                                      -43-
<PAGE>
 
          (c)  Seller shall be entitled to any credits or refunds of Taxes of
the Company for any period or periods ending on or before the Closing Date,
excluding any amounts reflected in the Closing Balance Sheet and taken into
account in the calculation of the Closing Payment. Any credits or refunds to
which Seller is entitled hereunder but which at any time subsequent to the
Closing Date are received by or credited to the Company, shall be promptly paid
to Seller following receipt of such refund or the utilization by the Company of
such credit.

          (d)  Buyer shall immediately notify Seller in writing upon receipt by
Buyer or the Company of notice of any tax audits, any pending or threatened
assessments with respect to Taxes or any requests by a taxing authority to
extend the applicable statute of limitations relating to periods and Taxes of
the Company for which Seller has any liability under this Agreement. Seller
shall have the right, at its cost, to determine whether to grant or deny any
such extensions, to control the Company's interests in any audit or other
examination by any taxing authority and to contest, resolve and defend against
any assessment for Taxes, notice of deficiency or other adjustment of Taxes of
or relating to the Company for taxable periods of the Company ending on or prior
to the Closing Date and to employ counsel of its choice, at its cost; provided,
                                                                      --------
however, that Buyer has received assurance reasonably acceptable to Buyer that
- -------
Seller will, to the extent required under this Agreement, pay any liability for
indemnification hereunder resulting therefrom.

          (e)  Buyer and Seller shall each provide the other with such
assistance as reasonably may be requested by either of them in connection with
the preparation of any Tax Return, any audit or other examination by any taxing
authority or any judicial or administrative proceedings related to liability for
Taxes (including refunds), and will each provide the other with any records or
information relevant to such return, audit or examination, proceedings or
determination as are in their possession or subject to their control. Such
assistance shall include making employees available on a mutually convenient
basis to provide additional information and explanation of any material provided
hereunder and shall include providing copies of any relevant Tax Returns. Each
party shall retain for a reasonable period of time (but not less than six (6)
years after Closing or until expiration of all applicable statutes of
limitation, whichever is later) and provide the other party with any records or
information or any other assistance (including, without limitation, making
employees

                                      -44-
<PAGE>
 
available to such other party) which may be relevant to such Tax Return, audit,
proceeding or determination. The party requesting assistance hereunder shall
reimburse the other for reasonable expenses incurred in providing such
assistance.

          (f)  Buyer shall, if so requested by Seller, cause the Company to
apply forthwith upon the request being made, at the expense of Seller, for any
available amnesty or other legal provision permitting the Company to close
preceding years for any Tax-related purpose.

     Section 13.6.  Recovery of Costs; Limitation of Damages.  If any dispute
                    ----------------------------------------
resolution, legal or equitable action is brought for the enforcement of this
Agreement, or because of an alleged dispute, breach, default, or
misrepresentation in connection with any of the provisions of this Agreement,
the successful or prevailing party or parties shall be entitled to recover
reasonable attorneys' fees and other costs incurred in that action, in addition
to any other relief to which it or they may be entitled. Under no circumstances
shall either party hereto be liable for any special, consequential, indirect or
punitive damages for any misrepresentation or breach of any provision of, or any
other matter arising pursuant to, this Agreement or any Transaction Document. In
addition, under no circumstances shall Damages include any losses, claims,
liabilities, damages, obligations, costs or expenses to the extent they affect
or relate to any business or operation of Buyer, including, without limitation,
the financial condition, prospects or operations thereof, other than the
business of the Company and each Subsidiary from and after the Closing.
