Section 2.4.   Condition on Assignment or Assumption of Contracts and Rights.

         Anything in this Agreement to the contrary notwithstanding, this
Agreement shall not constitute an agreement to assign or assume any Contract or
any claim or right or any benefit arising thereunder or resulting therefrom if
an attempted assignment or assumption thereof, without the Consent of a third
party thereto, would constitute a breach thereof. Any transfer or assignment to
Buyer by Seller of any property or property rights or any Contract which
requires the Consent of any third party shall be made subject to such Consent
being obtained. If such Consent is not obtained, or


                                       11

<PAGE>

if an attempted assignment thereof would be ineffective or would affect the
rights of Seller thereunder so that Buyer would not in fact receive all such
rights, Seller will cooperate with Buyer in any arrangement, including an
operating or other services agreement if reasonably required by Buyer,
reasonably designed to provide for Buyer, at Seller's cost, the benefits under
any such Contract or rights including, without limitation, enforcement for the
benefit of Buyer of any and all rights of Seller against a third party or
Governmental Body thereto arising out of the breach or cancellation by such
third party or Governmental Body or otherwise. To the extent that Buyer does
receive all of the benefits of any such Contract or rights pursuant to the
preceding sentence, such Contract shall be a Contract deemed to have been
assigned or transferred to Buyer pursuant to Section 2.2(b)(i). Seller shall not
be obligated (although Buyer is permitted at its expense) to provide any
arrangement or effect any assignment pursuant to this Section 2.4 which results
in an out-of-pocket cost or expenditure by Seller, or exposure to or
continuation of liability to Seller, resulting from such arrangements and
assignments, that would be reasonably estimated to be in excess of $250,000, in
the aggregate, except as otherwise expressly provided for by this Agreement, and
(ii) where Seller has continuing liability or exposure due to any third party's
failure to release Seller as a result of such third party's unwillingness to
accept Buyer as assignee; provided, however, that if Buyer , at Buyer's option,
indemnifies Seller from such continuing liability or exposure on terms and
conditions reasonably satisfactory to Seller, then Seller shall provide an
arrangement or assignment of the Contract to Buyer.

Section 2.5.   Settlement of Intercompany Accounts.

         At or prior to the Closing, Seller shall cause all intercompany
payables, receivables and loans between Seller's Southern Union Gas Division and
any of the Subsidiaries, on the one hand, and Seller and its Affiliates (other
than the Southern Union Gas Division and any of the Subsidiaries), on the other
hand, to be settled or cancelled.


                                  ARTICLE III.

                                 PURCHASE PRICE

Section 3.1.   Purchase Price.

         Subject to the terms and conditions of this Agreement, the aggregate
purchase price for the Assets owned directly by Seller and for the Stock (the
"Purchase Price") shall be an amount equal to Four Hundred Twenty Million
Dollars ($420,000,000) in cash, as adjusted in accordance with Section 3.2, and
the assumption by Buyer at Closing of the Assumed Liabilities.

Section 3.2.   Adjustment to Purchase Price.

              (a) Schedule 3.2 sets forth the Working Capital of the Business as
                  ------------
of June 30, 2002 (the "Base Statement"). "Working Capital" shall mean Current
Assets less Current Liabilities. "Current Assets" shall mean current assets of
the Business as reflected in the Base Statement as of the relevant date of
determination, but excluding Excluded Assets, intercompany receivables (that is,
receivables of the Business from divisions, subsidiaries or Affiliates of Seller
not a part of the Business) and prepaid insurance. "Current Liabilities" shall
mean the current liabilities of the Business as reflected in the Base Statement
as of the relevant date of determination, but excluding


                                       12

<PAGE>

Retained Liabilities (including liabilities associated with Excluded Assets),
intercompany payables (that is, payables of the Business to divisions,
subsidiaries or Affiliates of Seller not a part of the Business, and accrued
liability for Taxes for which Seller is liable. Within 90 days following the
Closing Date, Seller shall prepare and deliver to Buyer a statement (the
"Closing Statement"), which shall set forth in reasonable detail the amount of
Working Capital of the Business as of the Closing Date prepared on a basis
consistent with the Base Statement, and a calculation of the adjustment to the
Purchase Price that is payable based upon the difference between the Working
Capital in the Base Statement and the Working Capital in the Closing Statement.
Buyer agrees, at no cost to Seller, to give Seller and its authorized
representatives reasonable access to such employees, officers and other
facilities and such books and records of the Buyer and the Subsidiaries as are
reasonably necessary to allow Seller and its authorized representatives to
prepare the Closing Statement. The Base Statement shall be prepared using the
same accounting methods, policies, practices, procedures and adjustments as were
used in the preparation of the Financial Statements. The Closing Statement shall
be prepared using the same accounting methods, policies, practices, procedures
and adjustments as were used in the preparation of the Financial Statements.

              (b) Following its receipt from Seller of the Closing Statement,
Buyer shall have 15 Business Days to review the Closing Statement and to inform
Seller in writing of any disagreement (the "Objection") which it may have with
the Closing Statement, which objection shall specify in reasonable detail
Buyer's disagreement with the Closing Statement. If Seller does not receive the
Objection within such 15-Business Day period, the amount of Working Capital set
forth on the Closing Statement delivered pursuant to Section 3.2(a) shall be
deemed to have been accepted by Buyer and shall become binding upon Buyer. If
Buyer does timely deliver an Objection to Seller, Seller shall then have 15
Business Days from the date of receipt of such Objection (the "Review Period")
to review and respond to the Objection. Buyer and Seller shall attempt in good
faith to resolve any disagreements with respect to the determination of Working
Capital of the Business as of the Closing Date or the amount of the adjustment
to the Purchase Price. If they are unable to resolve all of their disagreements
with respect to the determination of Working Capital of the Business as of the
Closing Date or the amount of the adjustment to the Purchase Price within 15
Business Days following the expiration of Seller's Review Period, they may
refer, at the option of either Buyer or Seller, their differences to Deloitte &
Touche LLP, or if Deloitte & Touche LLP declines to accept such engagement, an
internationally recognized firm of independent public accountants selected
jointly by Buyer and Seller, who shall determine only with respect to the
differences so submitted, whether and to what extent, if any, the amount of
Working Capital of the Business as of the Closing Date set forth in the Closing
Statement requires adjustment. If Buyer and Seller are unable to so select the
independent public accountants within 15 Business Days of Deloitte & Touche LLP
declining to accept such engagement, either Buyer or Seller may thereafter
request that the American Arbitration Association make such selection (as
applicable, Deloitte & Touche LLP, the firm selected by Buyer and Seller or the
firm selected by the American Arbitration Association is referred to as the "CPA
Firm"). Buyer and Seller shall direct the CPA Firm to use its reasonable best
efforts to render its determination within 30 days after the issue is first
submitted to the CPA Firm. The CPA Firm's determination shall be conclusive and
binding upon Buyer and Seller. The fees and disbursements of the CPA Firm shall
be shared equally by Buyer and Seller. Buyer and Seller shall make readily
available to the CPA Firm all relevant books and records relating to the Closing
Statement and all other items reasonably requested by the CPA Firm. The Closing
Statement as


                                       13

<PAGE>

agreed to by Buyer and Seller or as determined by the CPA Firm shall be referred
to as the "Final Closing Statement."

              (c) In the event of a positive difference between Working Capital
on the Final Closing Statement from the Working Capital on the Base Statement,
then Buyer shall pay to Seller in cash the amount of such difference. In the
event of a negative difference between the Working Capital on the Base Statement
from the Working Capital on the Final Closing Statement, then Seller shall pay
to Buyer in cash the amount of such difference. All amounts payable under this
Section 3.2(c) shall be paid within five (5) Business Days of the determination
of the Final Closing Statement by wire transfer of immediately available funds
to a bank account in the United States of America designated in writing by the
recipient not less than one Business Day before such payment.

              (d) The Seller and Buyer hereby agree that, on or before the
Closing Date, all intercompany accounts of the Business due from or to Seller or
any divisions, subsidiaries or Affiliates of Seller not a part of the Business
shall be paid in full or offset, dividended or distributed to the Seller or its
Affiliates, or otherwise cancelled without payment.

         GENERALITY OF THE FOREGOING, BUYER ACKNOWLEDGES AND AGREES THAT, EXCEPT
         AS PROVIDED IN SECTIONS 5.7, 5.11 AND 5.14, THERE ARE NO
         REPRESENTATIONS OR WARRANTIES OF SELLER WITH RESPECT TO THE CONDITION
         OF THE ASSETS, COMPLIANCE WITH ENVIRONMENTAL LAWS AND ENVIRONMENTAL
         PERMITS OR THE PRESENCE OR RELEASES OF HAZARDOUS MATERIAL IN THE
         FIXTURES, SOILS, GROUNDWATER, SURFACE WATER OR AIR ON, UNDER OR ABOUT
         OR EMANATING FROM ANY OF THE PROPERTIES OR ASSETS OF SELLER OR ANY
         SUBSIDIARY.

Section 6.6.   Transition Plan.

         Within fifteen (15) days after the execution date of this Agreement,
Buyer shall deliver to Seller a list of its proposed representatives to a joint
transition team, which shall include individuals with expertise from various
functional specialties associated or involved in providing billing, payroll and
other support services provided to the Business by any automated or manual
process using facilities or employees that are not included among the Assets or
Transferred Employees. Seller will add its representatives, subject to Buyer's
approval, which approval shall not unreasonably be withheld, to such team within
fifteen (15) days after receipt of Buyer's list. Such team will be responsible
for preparing as soon as reasonably practicable after the execution date of this
Agreement, and timely implementing, a transition plan which will identify and
describe substantially all of the various transition activities that the parties
will cause to occur before and after the Closing and any other transfer of
control matters that any party reasonably believes should be addressed in such
transition plan, including the matters set forth on Exhibit 6.6. Buyer and
Seller shall use their commercially reasonable efforts to cause their
Representatives on such transition team to cooperate in good faith and take all
reasonable steps necessary to develop a mutually acceptable transition plan by
no later than sixty (60) days after the date of this Agreement. The terms and
conditions governing such transition activities will be more fully set forth in
a Transition Agreement reasonably satisfactory to the parties, including the
matters set forth on Exhibit 6.6, that will be executed and delivered by the
Buyer and Seller at the Closing.

Section 6.7.   Purchase of Leased Assets.

         Buyer and Seller shall use commercially reasonable efforts to arrange
for Buyer, on the Closing Date, to enter into new lease agreements covering the
motor vehicles and other equipment listed on Schedule 6.7 and leased by the
                                             ------------
lessors to Seller as identified on Schedule 6.7 (the "Leased Assets"), or if
unable to do so, then for Buyer to purchase any Leased Assets directly from any
such Lessor on, or promptly after, the Closing Date upon Buyer's payment
directly to any Lessor of the purchase price for any of the Leased Assets under
the applicable Lease. In either case, Buyer shall be responsible for, and shall
pay any related title transfer, registration, sales tax and similar fees,
including expenses of counsel, if any, associated with any such lease
arrangement or any transfer of title arising therefrom, or in lieu thereof,
including any motor vehicle title transfer and registration issues.

Section 6.8.  Meter Reading.

         On and prior to the Closing Date, Seller shall read the customer meters
in their normal cycle and in due course render the related bills to its
customers served by the Business. Seller shall also read each transportation
customer meter (collectively, "Large Volume Meters") on the day immediately
preceding the Closing Date. Seller shall provide Buyer with the last meter
reading from each of the Large Volume Meters made on the day immediately
preceding the Closing Date as soon as practical after the Closing Date. After
the Closing Date, Buyer shall read the customer meters for their first time, in
the normal cycle, and in due course render bills for service during the period
between the Seller's last reading in the normal cycle and the Buyer's first
reading in the normal cycle to the customers. Buyer shall determine the volume
of gas sold by the Seller prior to the Closing Date through Large Volume Meters
by the Seller's meter readings on the day immediately preceding Closing Date.
Buyer shall determine by allocation the volumes of gas sold by the Seller
through all meters other than Large Volume Meters, prior to the Closing Date,
and the gas sold by the Seller, on and after the Closing Date and prior to its
first meter reading through meters without charts. Such allocation shall be
consistent with the Seller's past practices for unbilled revenues. Once such
determinations have been made by Buyer, the estimated amounts of accounts
receivable and earned but unbilled revenue shall be adjusted based upon such
determinations for purposes of the Working Capital adjustment.

Section 6.9.   Insurance.

         Seller agrees to use commercially reasonable efforts to negotiate with
each of the insurance companies identified on Schedule 5.20 thereon with an
asterisk in order to provide Buyer the benefit of coverage under the Policies
for all "occurrences," as that term is defined by the Policies, arising from the
conduct of the Business on or prior to Closing.

Section 6.10.  Risk of Loss.

         The risk of any loss, damage, impairment, confiscation or condemnation
of any of the Assets from any cause whatsoever shall be borne by Seller at all
times prior to the Closing, and by Buyer at all times thereafter. If any such
loss, damage or impairment, confiscation or condemnation occurs, Seller shall
apply the proceeds of any insurance policy, judgment or award with respect
thereto to impair, replace or restore the Assets as soon as possible to their
prior condition; provided, however, anything contained in this Agreement to the
contrary notwithstanding, Seller shall not be obligated to expend sums in excess
of the proceeds of any insurance policy, judgment or award with respect to any
loss, damage, impairment, confiscation or condemnation of any of the Assets in
order to repair, replace or restore such Assets to their prior condition. The
provisions of this Section 16.10 shall apply in the event ("Casualty Event") of
any damage or destruction to the Assets which would result in the non-occurrence
of a condition precedent to Buyer's obligation to consummate this Agreement. If
a Casualty Event shall occur, Buyer at its option, may proceed to close this
Agreement on the Closing Date, in which event Seller shall pay or assign to
Buyer the proceeds from any insurance policies covering Assets subject to the
Casualty Event to the extent such proceeds are received by or payable to Seller
and have not been used in or committed to the restoration or replacement of
Assets subject to the Casualty Event as of the Closing Date.

Section 9.1.   Termination Rights.

         This Agreement may be terminated in its entirety at any time prior to
the Closing:

              (a) By the mutual written agreement of Seller and Buyer;

              (b) By Buyer, on the one hand, or Seller, on the other hand, in
writing if there shall be in effect a nonappealable Order prohibiting, enjoining
or restricting the transactions contemplated by this Agreement;

              (c) By Buyer, upon the breach in any material respect of any of
the representations and warranties of Seller contained herein or in the failure
by Seller to perform and comply in any material respect with any of the
agreements and obligations required by this Agreement to be performed or
complied with by Seller, provided that all such breaches or failures are
reasonably likely to result in a Material Adverse Effect and are not cured or
otherwise addressed by Seller in a manner reasonably acceptable to Buyer within
fifteen (15) days of Seller's receipt of a written notice from Buyer that such
breaches or failures have occurred (or significant efforts have not been
commenced to cure such misrepresentations or breaches if they are susceptible to
cure but not capable of being cured within such fifteen (15) days);

              (d) By Seller, upon the breach in any material respect of any of
the representations and warranties of Buyer contained herein or the failure by
Buyer to perform and comply in any material respect with any of the agreements
and obligations required by this Agreement to be performed or complied with by
Buyer, provided that such breach or failure is not cured or otherwise addressed
by Buyer in a manner reasonably acceptable to Seller within fifteen (15) days of
Buyer's receipt of a written notice from Seller that such a breach or failure
has occurred (or significant efforts have not been commenced to cure such
misrepresentation or breach if it is susceptible to cure but not capable of
being cured within such fifteen (15) days);

              (e) By either party in writing if the Closing has not occurred
within ninety (90) days after the execution date specified in the first

available to any party that is in material breach of its representations,
warranties, covenants or agreements contained herein; and provided further that
in the event either party's conditions precedent to Closing set forth in Article
VII have not been satisfied prior to the Upset Date but reasonably are capable
of being satisfied thereafter, then either party may request from the other up
to an aggregate of three (3) thirty (30) day extensions of the Upset Date, the
other party's approval of such extension(s) not unreasonably to be withheld (for
the avoidance of doubt, the Upset Date shall not be extended by more than 90
days); or

              (f) By Seller, if at Closing Buyer fails to make the payments
required to be made by Buyer at Closing.

Section 9.2.   Limitation on Right to Terminate: Effect of Termination.

               (a) A party shall not be allowed to exercise any right of
termination pursuant to Section 9.1 if the event giving rise to the termination
right shall be due to the willful failure of such party seeking to terminate
this Agreement to perform or observe in any material respect any of the
covenants or agreements hereof to be performed or observed by such party.

               (b) If this Agreement is terminated as permitted under Section
9.1, such termination shall be without liability of or to any party to this
Agreement, or any shareholder or Representative of such party; provided,
however, that if such termination shall result from the willful failure of any
party to fulfill a condition to the performance of any other party or to perform
a covenant of this Agreement or from a material and willful breach by any party
to this Agreement (it being understood that the failure to cure a breach shall
not, by itself, be a willful breach of this Agreement), then such party shall
(subject to the limitation set forth in Sections 9.2(c) and 9.2(d), and the last
sentence of this Section 9.2(b)) be fully liable for any and all damages
sustained or incurred by the other party. If prior to Closing either party to
this Agreement resorts to legal proceedings to enforce this Agreement, the
prevailing party in such proceedings shall be entitled to recover all costs
incurred by such party including reasonable attorney's fees, in addition to any
other relief to which such party may be entitled; provided, however, and
notwithstanding anything to the contrary in this Agreement, in no event shall
either party be entitled to receive any punitive, exemplary, special, remote,
speculative, indirect or consequential damages (including any damages on account
of lost profits or opportunities).

               (c) If Seller terminates this Agreement pursuant to Section
9.1(d) or Section 9.1(f), then Seller shall be entitled to payment of the Escrow
Amount as liquidated damages free of any claims by Buyer or any other Person
with respect thereto (the parties hereby acknowledging that the extent of
damages to Seller occasioned by such breach or default by Buyer would be
impossible or extremely difficult to ascertain and that the amount of the Escrow
Amount is a fair and reasonable estimate of such damages under the
circumstances). If this Agreement is terminated for any reason other than as set
forth in the preceding sentence, then the Escrow Amount shall be paid to Buyer,
free of any claims by Seller or any other Person with respect thereto.

               (d) If Buyer terminates this Agreement pursuant to Section
9.1(c), then Buyer shall be entitled to recover from Seller $30,000,000 as
liquidated damages (the parties hereby acknowledging that the extent of damages
to Buyer occasioned by such breach or default by Seller would be impossible or
extremely difficult to ascertain and that the amount of such liquidated damages
is a fair and reasonable estimate of such damages under the circumstances).

Section 9.3.   Escrow Amount.

         Concurrently with the execution of this Agreement, Buyer has made a
deposit of $30,000,000 (the "Escrow Amount") with J.P. Morgan Chase National
Bank, New York, NY (the "Escrow Agent"), to be held by the Escrow Agent pursuant
to the terms of an Escrow Agreement, dated as of the date of this Agreement,
among Buyer, Seller and the Escrow Agent as security for the payment of


                                       35

<PAGE>

the liquidated damages due from Buyer to Seller pursuant to Section 9.1(d) or
9.1(f), in which event Seller shall be entitled to give notice to the Escrow
Agent and Buyer, causing the prompt release and payment of the Escrow Amount to
Seller by the Escrow Agent pursuant to the Escrow Agreement.

                                EMPLOYEE MATTERS

Section 10.1.  Employee Agreement.

         The parties have addressed the transfer of employees and employee
benefit matters in a separate agreement, entitled Employee Agreement, the terms
and provisions of which are incorporated into this Agreement as if fully set
forth herein and a copy of which is attached hereto as Exhibit 10.1 (the
                                                       ------------
"Employee Agreement").


                                   ARTICLE XI.

                                   TAX MATTERS

Section 11.1.  Purchase Price Allocation.

         Within 180 days after the Closing Date, Buyer and Seller shall use
their good faith efforts to agree upon the allocation (the "Allocation") of the
Purchase Price, the Assumed Liabilities and other relevant items (including, for
example, adjustments to the Purchase Price) to the individual assets or classes
of assets within the meaning of Section 1060 of the IRC. If Buyer and Seller
agree to such Allocation, Buyer and Seller covenant and agree that (i) the
values assigned to the assets by the parties' mutual agreement shall be
conclusive and final for all purposes, and (ii) neither Buyer nor Seller will
take any position before any Governmental Body or in any Proceeding that is in
any way inconsistent with such Allocation. Notwithstanding the foregoing, if
Buyer and Seller cannot agree to an Allocation, Buyer and Seller covenant and
agree to file, and to cause their respective Affiliates to file, all Tax Returns
and schedules thereto (including, for example, amended returns, claims for
refund, and those returns and forms required under Section 1060 of the IRC and
any Treasury regulations promulgated thereunder) consistent with each of such
party's good faith Allocations, unless otherwise required because of a change in
any Legal Requirement.

Section 11.2.  Cooperation with Respect to Like-Kind Exchange.

         Buyer agrees that Seller may, at Seller's election prior to the Closing
Date, direct that all or a portion of the Purchase Price be delivered to a
"qualified intermediary" (as defined in Treasury Regulation Section 1.1031(k) -
(g)(4)) as to enable Seller's relinquishment of the Assets to qualify as part of
a like-kind exchange of property covered by Section 1031 of the IRC. If Seller
so elects, Buyer shall cooperate with Seller (but without being required to
incur any out-of-pocket costs in the course thereof) in connection with Seller's
efforts to effect such like-kind exchange, which cooperation shall include,
without limitation, taking such actions as Seller requests in order to enable
Seller to qualify such transfer as part of a like-kind exchange of property
covered by Section 1031 of the IRC (including any actions required to facilitate
the use of a "qualified intermediary"), and Buyer agrees that Seller may assign
all or part of its rights and delegate all or part of its obligations under this
Agreement to a person or entity acting as a qualified intermediary to qualify
the transfer of the


                                       36

<PAGE>

Assets as part of a like-kind exchange of property covered by Section 1031 of
the IRC. Buyer and Seller agree in good faith to use reasonable efforts to
coordinate the transactions contemplated by this Agreement with any other
transactions engaged in by either Buyer or Seller; provided that such efforts
are not required to include an unreasonable delay in the consummation of the
transactions contemplated by this Agreement.

Section 11.3.  Transaction Taxes.

         All transfer, documentary, recording, notarial, sales, use,
registration, stamp and other similar taxes, fees and expenses (including, but
not limited to, all applicable stock transfer, real estate transfer or gains
Taxes and including any penalties, interest and additions to such tax)
("Transaction Taxes") incurred in connection with this Agreement and the
transactions contemplated hereby shall be borne by Buyer, to the extent that
Buyer is legally obligated to pay those Transaction Taxes, and shall be borne by
the Seller, to the extent that Seller is legally obligated to pay Transaction
Taxes, regardless of whether the tax authority seeks to collect such Taxes from
Seller or Buyer. Buyer and the Seller shall cooperate in timely making and
filing all Tax Returns as may be required to comply with the provisions of laws
relating to such Transaction Taxes. Seller shall prepare all tax filings related
to any Transaction Taxes. Fifteen (15) days prior to making such filings, Seller
shall provide to Buyer Seller's work papers for Buyer's review and approval. Ten
(10) days prior to the filing date, Buyer shall provide to Seller approval of
such work papers. Buyer shall also be responsible for (i) administering the
payment of such Transaction Taxes, (ii) defending or pursuing any proceedings
related thereto, and (iii) paying any expenses related thereto. Seller shall
give prompt written notice to Buyer of any proposed adjustment or assessment of
any Transaction Taxes with respect to the transaction, or of any examination of
said transaction in a sales, use, transfer or similar tax audit. In any
proceedings, whether formal or informal, Seller shall permit Buyer to
participate and control the defense of such proceeding and shall take all
actions and execute all documents required to allow such participation. Seller
shall not negotiate a settlement or compromise of any Transaction Taxes without
the prior written consent of Buyer, which consent shall not be unreasonably
withheld or delayed.

Section 11.4.  Real and Personal Property Taxes.

         All real and personal property Taxes and assessments arising with
respect to the Assets shall be prorated between Buyer and Seller based on the
relative periods of time the Assets were owned by each respective party or their
respective Affiliates during the fiscal period for which such Taxes are imposed
by the applicable taxing jurisdiction (as such fiscal period is or may be
reflected on the bill rendered by such taxing jurisdiction). Upon receipt by
Buyer of the tax bill, invoice or other statement regarding such real and
personal property Taxes, Buyer shall calculate the pro rata share of such tax
bill, invoice or other statement attributable to Buyer and Seller. Buyer then
shall forward, as soon as practicable, to Seller a copy of such tax bill,
invoice or statement along with the supporting documentation relating to the
calculation of the pro rata share to Seller. Seller then shall forward to Buyer
payment in immediately available funds of its pro rata share of such Taxes as
soon as practicable in advance of the due date of the tax bill, invoice or
statement and in time to avoid the incurrence of penalties or interest. Upon its
receipt of such payment, Buyer will pay the full amount of the tax bill, invoice
or statement to the applicable taxing authority. In the event Seller first


                                       37

<PAGE>

receives a tax bill, invoice or statement relating to the Assets from a taxing
authority, Seller shall immediately forward such tax bill, invoice or statement
to Buyer.

Section 11.5.  Taxes Based on Revenues.

         All sales, franchise, gross receipts and other similar Taxes based upon
revenues of the Business shall be prorated between Buyer and Seller, with Seller
being obligated to reimburse Buyer only for the portion of any such Tax that is
applicable to the cash received by Seller prior to the Closing Date that relates
to the revenues of the Business being taxed. Upon receipt by Buyer of the tax
bill, invoice or other statement regarding such Taxes, Buyer shall calculate the
pro rata share of such tax bill, invoice or other statement attributable to
Buyer and Seller. Buyer then shall forward, as soon as practicable, to Seller a
copy of such tax bill, invoice or statement along with the supporting
documentation relating to the calculation of the pro rata share to Seller.
Seller then shall forward to Buyer payment in immediately available funds of its
pro rata share of such Taxes as soon as practicable in advance of the due date
of the tax bill, invoice or statement and in time to avoid the incurrence of
penalties or interest. Upon its receipt of such payment, Buyer will pay the full
amount of the tax bill, invoice or statement to the applicable taxing authority.
In the event Seller first receives a tax bill, invoice or statement relating to
the revenues of the Business from a taxing authority, Seller shall immediately
forward such tax bill, invoice or statement to Buyer.


                                  ARTICLE XII.

Representatives, Affiliates, successors and permitted assigns (collectively, the
"Buyer Indemnitees") from and against any and all Losses as incurred by a Buyer
Indemnitee, payable quarterly upon proper written request, and directly
resulting from:

               (a) any representations and warranties made by Seller in this
Agreement not being true and correct when made or when required by this
Agreement to be true and correct, or any breach or default by Seller in the
performance of its covenants, agreements, or obligations under this Agreement or
the Employee Agreement required to be performed prior to Closing;

               (b) any breach or default by Seller in the performance of its
covenants, agreements, or obligations under this Agreement or the Employee
Agreement required to be performed after Closing; and

               (c) Seller's failure to perform or satisfy any of the Retained
Liabilities or liabilities associated with the Excluded Assets.

<PAGE>

(collectively, the "Seller Indemnitees") from and against any and all Losses as
incurred by a Seller Indemnitee, payable quarterly upon proper written request,
and directly resulting from:

               (a) any representations and warranties made by Buyer in this
Agreement not being true and correct when made or when required by this
Agreement to be true and correct, or any breach or default by Buyer in the
performance of its covenants, agreements, or obligations under this Agreement or
the Employee Agreement required to be performed prior to Closing;

               (b) any breach or default by Buyer in the performance of its
covenants, agreements, or obligations under this Agreement or the Employee
Agreement required to be performed after Closing; and

               (c) the Assumed Liabilities.

Section 12.3.  Limitations on Seller's Liability.

         Notwithstanding anything to the contrary in this Agreement, the
liability of Seller under this Agreement and any documents delivered in
connection herewith or contemplated hereby shall be limited as follows:

               (a) IN NO EVENT SHALL SELLER BE LIABLE TO THE BUYER INDEMNITEES
FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR
SPECULATIVE DAMAGES; provided, however, that if Buyer is held liable to a third
party for any of such damages and Seller is obligated to indemnify Buyer for the
matter that gave rise to such damages, then Seller shall be liable for, and
obligated to reimburse Buyer for, such damages.

               (b) Except as provided below, the representations and warranties
of Seller set forth in this Agreement shall survive the Closing until June 30,
2003; provided however, that the representations and warranties set forth in
Section 5.2 (Authority Relative to this Agreement and Binding Effect), Section
5.5 (Title to Assets; Encumbrances), and Section 5.18 (Brokers) shall survive
indefinitely; the representations and warranties set forth in Section 5.6
(Financial Statements), Section 5.14 (Environmental Matters), Section 5.15
(Absence of Certain Changes or Events), and Section 5.21 (Absence of Undisclosed
Liabilities) shall survive until March 31, 2004; and the representations and
warranties set forth in Section 5.9 (Taxes) shall survive for a period equal to
the applicable statute of limitations for the taxable year for each Tax. The
other terms of this Agreement and the agreements delivered in connection
herewith shall survive the Closing. All representations and warranties,
covenants and agreements of Seller under this Agreement and the indemnities
granted by Seller in Section 12.1 shall terminate at 5:00 p.m., East Coast time,
on the applicable survival termination date set forth above; provided, however,
that such indemnities shall survive with respect only to any specific matter
that is the subject of a proper Claim Notice delivered in good faith in
compliance with the requirements of this Section 12.3 until the earlier to occur
of (A) the date on which a final nonappealable resolution of the matter
described in such Claim Notice has been reached, including the determination of
all related Losses, if any, regardless of when such Losses are finally
determined or (B) the date on which the matter described in such Claim Notice
has otherwise reached final resolution, including the determination of all
related Losses, if any, regardless of when such Losses are finally determined.
In no event shall any amounts be recovered from Seller under Section 12.1 or


                                       39

<PAGE>

otherwise for any matter for which a Claim Notice is not delivered to Seller
prior to the close of business on the applicable date set forth above.

               (c) Notwithstanding anything to the contrary in this Agreement,
in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable
in any way whatsoever to the Buyer Indemnitees, for any Losses otherwise subject
to indemnification by Seller (determined after giving effect to the other
provisions of this Section 12.3) until the Buyer Indemnitees have incurred
otherwise indemnifiable Losses that in the aggregate exceed $5,000,000 (the
"Deductible"), after which Seller shall then be liable for indemnifiable Losses
incurred by the Buyer Indemnitees in excess of such amount up to the maximum
amount set forth in Section 12.3(d). For the purposes of calculating the
Deductible, none of the dollar limitations or Material Adverse Effect qualifiers
contained in the representations and warranties of Article V shall be included
in calculating Losses that comprise the Deductible.

               (d) Notwithstanding anything to the contrary in this Agreement,
in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable
in any way whatsoever to the Buyer Indemnitees, for any Losses otherwise subject
to indemnification by Seller (determined after giving effect to the other
provisions of this Section 12.3) that in the aggregate exceed $42,000,000.

               (e) No amount shall be recovered from Seller for the breach or
untruth of any of Seller's representations, warranties, covenants or agreements,
or for any other matter, to the extent that Buyer had knowledge of such breach,
untruth or other matter at or prior to the Closing, no shall Buyer be entitled
to rescission with respect to any such matter, unless and except to the extent
that Buyer has satisfied Section 6.2(d).

               (f) Seller shall have no liability for any claim or Loss (A) that
would be covered by insurance maintained by or for the benefit of Buyer or any
Affiliate of Buyer (including any such insurance coverage applicable to the
Business the benefit of which the Buyer will realize, if Buyer were to maintain
insurance coverage as is customary for the industry in which the Business is
conducted consistent with the coverage described in Schedule 5.20) or for which
Buyer otherwise recovers payments in respect of such Loss from any other
source(s) (whether in a lump sum or stream of payments) or (B) that is the type
normally recoverable by the Business through rates and is in fact substantially
recovered by Buyer through rates, provided that Buyer shall have made a good
faith effort to recover any such claim or loss through rates and that such
recovery is not indeterminable due to the terms of any rate settlement agreed to
by Buyer, or is otherwise recovered by Buyer through rates. No cost or expense
relating to any such claim or Loss that is actually recovered based on the
foregoing shall be included in determining the extent of Losses suffered by the
Buyer Indemnitees for purposes of Section 12.3(c) or Section 12.3(d). Buyer
agrees to use its commercially reasonable efforts to give timely and effective
written notice to the appropriate insurance carrier(s) of any occurrence or
circumstances which, in the judgment of Buyer consistent with its customary risk
management practices, appear likely to give rise to a claim against Buyer that
is likely to involve one or more insurance policies of Buyer. Any such notice
shall be given in good faith by Buyer without regard to the possibility of
indemnification payments by Seller under Section 12.1, and shall be processed by
Buyer in good faith and in a manner consistent with its risk management
practices involving claims for which no third party contractual indemnification
is available. Buyer agrees that (i) if it is entitled to receive payment from
Seller for a Loss, and (ii) if


                                       40

<PAGE>

Buyer has obtained insurance which may cover the claim or matter giving rise to
such Loss, then (iii) such insurance shall be primary coverage and Buyer will
make a claim under such insurance (if such claim can be made in good faith)
before enforcing its right to receive payment from Seller. If at any time
subsequent to the receipt by a Buyer Indemnitee of an indemnity payment from
Seller hereunder, such Buyer Indemnitee (or any Affiliate thereof) receives any
recovery, settlement or other similar payment with respect to the Loss for which
it receives such indemnity payment, such Buyer Indemnitee shall promptly pay to
Seller an amount equal to the amount of such recovery, less any expense incurred
by such Buyer Indemnitee (or its Affiliates) in connection with such recovery,
but in no event shall any such payment exceed the amount of such indemnity
payment.

               (g) Notwithstanding any language contained in any Related
Document (including deeds and other conveyance documents relating to the Real
Property), the representations and warranties of Seller set forth in this
Agreement will not be merged into any such Related Document and the
indemnification obligations of Seller, and the limitations on such obligations,
set forth in this Agreement shall control. No provision set forth in any such
Related Document shall be deemed to enlarge, alter or amend the terms or
provisions of this Agreement.

Section 12.4.  Limitation on Buyer's Liability.

         IN NO EVENT SHALL BUYER BE LIABLE TO THE SELLER INDEMNITEES FOR ANY
EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE
DAMAGES; provided, however, that if Seller is held liable to a third party for
any of such damages and Buyer is obligated to indemnify Seller for the matter
that gave rise to such damages, then Buyer shall be liable for, and obligated to
reimburse Seller for, such damages.

Section 12.5.  Claims Procedure.

               (a) All claims for indemnification under Section 12.1 or 12.2, or
any other provision of this Agreement except as otherwise expressly provided in
this Agreement, shall be asserted and resolved pursuant to this Article XII. Any
Person claiming indemnification hereunder is referred to as the "Indemnified
Party" and any Person against whom such claims are asserted hereunder is
hereinafter referred to as the "Indemnifying Party." In the event that any
Losses are asserted against, sought to be collected from or threatened to be
sought from an Indemnified Party, by a third party, including a Governmental
Body, said Indemnified Party shall with reasonable promptness provide to the
Indemnifying Party a Claim Notice. The Indemnifying Party shall not be obligated
to indemnify the Indemnified Party with respect to any such Losses if the
Indemnified Party fails to notify the Indemnifying Party thereof in accordance
with the provisions of this Agreement in reasonably sufficient time so that the
Indemnifying Party's ability to defend against the Losses is not prejudiced. The
Indemnifying Party shall have thirty (30) days from the personal delivery or
receipt of the Claim Notice (the "Notice Period") to notify the Indemnified
Party (i) whether or not it disputes the liability of the Indemnifying Party to
the Indemnified Party hereunder with respect to such Losses and/or (ii) whether
or not it desires, at the sole cost and expense of the Indemnifying Party, to
defend the Indemnified Party against such Losses; provided, however, that any
Indemnified Party is hereby authorized prior to and during the Notice Period to
file any motion, answer or other pleading that it shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party (and of


                                       41

<PAGE>

which it shall have given notice and opportunity to comment to the Indemnifying
Party) and not prejudicial to the Indemnifying Party. In the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against such Losses, the Indemnifying
Party shall have the right to defend all appropriate proceedings, and with
counsel of its own choosing, which proceedings shall be promptly settled or
prosecuted by them to a final conclusion. If the Indemnified Party desires to
participate in, but not control, any such defense or settlement it may do so at
its sole cost and expense. If requested by the Indemnifying Party, the
Indemnified Party agrees to cooperate with the Indemnifying Party and its
counsel in contesting any Losses that the Indemnifying Party elects to contest
or, if appropriate and related to the claim in question, in making any
counterclaim against the Person asserting the third party Losses, or any
cross-complaint against any Person. No claim may be settled or otherwise
compromised without the prior written consent of the Indemnifying Party.

               (b) The Indemnified Party shall provide reasonable assistance to
the Indemnifying Party and provide access to its books, records and personnel as
the Indemnifying Party reasonably requests in connection with the investigation
or defense of the Losses. The Indemnifying Party shall promptly upon receipt of
reasonable supporting documentation reimburse the Indemnified Party for
out-of-pocket costs and expenses incurred by the latter in providing the
requested assistance.

               (c) With regard to third party claims for which Buyer or Seller
is entitled to indemnification under Section 12.1 or 12.2, such indemnification
shall be paid by the Indemnifying Party upon: (i) the entry of an Order against
the Indemnified Party and the expiration of any applicable appeal period; or
(ii) a settlement with the consent of the Indemnifying Party, provided that no
such consent need be obtained if the Indemnifying Party fails to respond to the
Claim Notice as provided in Section 12.4(a). Notwithstanding the foregoing but
subject to Section 12.4(a), and provided that there is no dispute as to the
applicability of indemnification, expenses of counsel to the Indemnified Party
shall be reimbursed on a current basis by the Indemnifying Party as if such
expenses are a liability of the Indemnifying Party.

Section 12.6.  Exclusive Remedy.

         Except as otherwise provided in Sections 3.2(b), 6.4, 9.2, 9.3 or 13.6,
the rights, remedies and obligations of the Buyer Indemnitees and the Seller
Indemnitees set forth in this Article XII will be the exclusive rights, remedies
and obligations of such Persons after the Closing with respect to all
post-Closing claims relating to this Agreement, the events giving rise to this
Agreement and the transactions provided for herein or contemplated hereby or
thereby. No Proceeding for termination or rescission, or claiming repudiation,
of this Agreement may be brought or maintained by either party against the other
following the Closing Date no matter how severe, grave or fundamental any
breach, default or nonperformance may be by one party. Accordingly, the parties
hereby expressly waive and forego any and all rights they may possess to bring
any such Proceeding.

Section 12.7.  Indemnification for Negligence.

         WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE INDEMNIFICATION
OBLIGATIONS SET FORTH IN THIS AGREEMENT, AN INDEMNIFIED PARTY SHALL BE ENTITLED
TO INDEMNIFICATION HEREUNDER IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF
WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE
RESULT OF THE SOLE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY,
VIOLATION OF ANY LAW OR OTHER LEGAL FAULT OF OR BY SUCH INDEMNIFIED PARTY. THE
PARTIES AGREE THAT THIS PARAGRAPH CONSTITUTES A CONSPICUOUS LEGEND.

Section 12.8.  Waiver and Release.

         Buyer, on behalf of itself and each other Buyer Indemnitee, hereby
forever waives, relieves, releases and discharges the Seller Indemnitees and
their successors and assigns from any and all rights, liabilities, Proceedings
(including future Proceedings) and Losses of any Buyer Indemnitee, whether known
or unknown at the Closing Date, which any Buyer Indemnitee has or incurs, or may
in the future have or incur, arising out of or related to any Assumed Liability.

all costs and expenses of its performance of and compliance with this Agreement,

herein, Buyer and Seller will split on a 50/50 basis all filing fees associated

Section 13.3.  Assignment.

         This Agreement may not be assigned, by operation of law or otherwise,
by any party hereto without the prior written consent of the other party hereto,
such consent not to be unreasonably


                                       44

<PAGE>

withheld; provided, however, in the event of any such assignment by a party by
operation of law without the consent of the other party as required above, such
other party may consent to such assignment after it has occurred and, in such
event, this Agreement and all the provisions hereof shall be binding upon the
Person receiving such assignment by operation of law. Notwithstanding the
foregoing, Seller may assign all or part of its rights or delegate all or part
of its duties under this Agreement, without the prior written consent of Buyer,
to a qualified intermediary chosen by Seller to structure all or part of the
transactions contemplated hereby as a like-kind exchange of property covered by
Section 1031 of the IRC.

Section 13.4.  Successor Bound.

         Subject to the provisions of Section 13.3, this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

Section 13.5.  Governing Law.

         The validity, performance, and enforcement of this Agreement and all
Related Documents, unless expressly provided to the contrary, shall be governed
by the laws of the State of Delaware without giving effect to the principles of
conflicts of law of such state.

Section 13.6.  Dispute Resolution.

         Except as otherwise provided in Sections 3.2(b) and 6.4, and this
Section 13.6, any dispute, controversy or claim between the parties relating to,
arising out of or in connection with this Agreement (or any subsequent
agreements or amendments thereto), including as to its existence,
enforceability, validity, interpretation, performance or breach or as to
indemnification or damages, including claims in tort, whether arising before or
after the termination of this Agreement (any such dispute, controversy or claim
being herein referred to as a "Dispute") shall be settled without litigation and
only by use of the following alternative dispute resolution procedure:

               (a) At the written request of a party, each party shall appoint a
knowledgeable, responsible representative to meet and negotiate in good faith to
resolve any Dispute. The discussions shall be left to the discretion of the
representatives. Upon agreement, the representatives may utilize mediation to
assist in the resolution of the Dispute. Discussions and correspondence among
the parties' representatives for purposes of these negotiations and any
mediation shall be treated as confidential information developed for the
purposes of settlement, exempt from discovery and production, and without the
concurrence of both parties shall not be admissible in the arbitration described
below, or in any lawsuit. Documents identified in or provided with such
communications, which are not prepared for purposes of the negotiations, are not
so exempted and may, if otherwise admissible, be admitted in the arbitration.

               (b) If negotiations between the representatives of the parties do
not resolve the Dispute within sixty (60) days of the initial written request,
the Dispute shall be submitted to binding arbitration by a single arbitrator
pursuant to the commercial arbitration rules, as then amended and in effect, of
the American Arbitration Association (the "Rules"). Either party may demand such
arbitration in accordance with the procedures set out in the Rules. The
arbitrator shall be selected by


                                       45

<PAGE>

agreement of the parties within thirty (30) days of the demand for arbitration
and if no such agreement has been reached, then in accordance with the Rules and
shall be reasonably acceptable to both parties. The arbitration hearing shall
take place in Chicago, Illinois. The arbitration proceedings shall be commenced
within one hundred twenty (120) days of a party's demand for arbitration
properly submitted in accordance with the Rules. The arbitrator shall determine
what discovery, if any, shall be appropriate, shall control the scheduling of
the same and rule on all discovery disputes. At the arbitration hearing, each
party may make written and oral presentations to the arbitrator, present
testimony and written evidence and examine witnesses. The arbitrator shall have
authority to award only actual damages and shall not have the authority to award
consequential, punitive or exemplary damages or any other form of relief. The
arbitrator shall rule on the Dispute by issuing a written reasoned opinion
within sixty (60) days after the close of hearings. The arbitrator shall
determine the date on which the hearings are closed. The arbitrator's decision
shall be binding and final. Judgment upon the award rendered by the arbitrator
may be entered in any court having jurisdiction.

               (c) Each party will bear its own costs and expenses in connection
with the arbitration proceedings with respect to any Dispute; provided, however,
that:

                           if the arbitrator  determines that the position taken
in the Dispute by the  nonprevailing  party taken as a whole is unreasonable,
the arbitrator may order the nonprevailing party to bear such fees and expenses,
and reimburse the prevailing party for all or such portion of its reasonable
costs and expenses in connection with the arbitration proceedings with respect
to such Dispute, as the arbitrator shall reasonably determine to be fair under
the circumstances;

                           if any party files a judicial or administrative
action asserting claims properly subject to arbitration as prescribed herein,
and the other party successfully stays such action and/or compels arbitration of
said claims, the party filing said action shall pay the other party's costs and
expenses incurred in seeking such stay and/or compelling arbitration, including
reasonable attorneys' fees; and

                           each party shall pay one-half of the fees and
expenses of the arbitrator and the American Arbitration Association.

               (d) Notwithstanding any other provision of this Agreement, (i)
either party may commence an action to compel compliance with this Section 13.6
and (ii) if any party, as part of a Dispute, seeks injunctive relief or any
other equitable remedy, including specific enforcement, then in either instance
such party shall be permitted to seek such injunctive or equitable relief in the
U.S. District Court of the Northern District of Illinois, before, during or
after the pendency of a mediation or arbitration proceeding under this Section
13.6.

Section 13.7.  Cooperation.

         Each of the parties hereto agrees to use its commercially reasonable
efforts to take or cause to be taken all action, and to do or cause to be done
all things necessary, proper or advisable under applicable laws, regulations or
otherwise, to consummate and to make effective the transactions


                                       46

contemplated by this Agreement, including the timely performance of all actions
and things contemplated by this Agreement to be taken or done by each of the
parties hereto.

Section 13.8.  Construction of Agreement.

         The terms and provisions of this Agreement represent the results of
negotiations between Buyer and Seller, each of which has been represented by
counsel of its own choosing, and neither of which has acted under duress or
compulsion, whether legal, economic or otherwise. Accordingly, the terms and
provisions of this Agreement shall be interpreted and construed in accordance
with their usual and customary meanings, and Buyer and Seller hereby waive the
application in connection with the interpretation and construction of this
Agreement of any rule of law to the effect that ambiguous or conflicting terms
or provisions contained in this Agreement shall be interpreted or construed
against the party whose attorney prepared the executed draft or any earlier
draft of this Agreement. It is understood and agreed that neither the
specification of any dollar amount in the representations and warranties
contained in this Agreement nor the inclusion of any specific item in the
Schedules or Exhibits is intended to imply that such amounts or higher or lower
amounts, or the items so included or other items, are or are not material, and
none of the parties shall use the fact of the setting of such amounts or the
fact of any inclusion of any such item in the Schedules or Exhibits in any
dispute or controversy between the parties as to whether any obligation, item or
matter is or is not material for purposes hereof. The word "including" in this
Agreement shall mean including without limitation. Words in the singular shall
be held to include the plural and vice versa and words of one gender shall be
held to include the other genders as the context requires. The terms "hereof,"
"herein," and "herewith" and words of similar import shall, unless otherwise
stated, be construed to refer to this Agreement as a whole (including all of the
Schedules and Exhibits hereto) and not to any particular provision of this
Agreement, and Article, Section, paragraph, Exhibit and Schedule references are
to the Articles, Sections, paragraphs, Exhibits and Schedules to this Agreement
unless otherwise specified.

Section 13.9.  Publicity.

         No party hereto shall issue, make or cause the publication of any press
release or other announcement with respect to this Agreement or the transactions
contemplated hereby, or otherwise make any disclosures relating thereto, without
the consent of the other party, such consent not to be unreasonably withheld or
delayed; provided, however, that such consent shall not be required where such
release or announcement is required by applicable law or the rules or
regulations of a securities exchange, in which event the party so required to
issue such release or announcement shall endeavor, wherever possible, to furnish
an advance copy of the proposed release to the other party.

Section 13.10. Waiver.

         Except as otherwise expressly provided in this Agreement, neither the
failure nor any delay on the part of any party to exercise any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise or waiver of any such right, power or privilege preclude any
other or further exercise thereof, or the exercise of any other right, power or
privilege available to each party at law or in equity.

Section 13.11. Parties in Interest.

         This Agreement (including the documents and instruments referred to
herein) is not intended to confer upon any Person, other than the parties hereto
and their successors and permitted assigns, any rights or remedies hereunder;
provided, however, that the indemnification provisions in Article XII shall
inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as
provided therein.

Section 13.12. Section and Paragraph Headings.

         The section and paragraph headings in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

Section 13.13. Amendment.

         This Agreement may be amended only by an instrument in writing executed
by the parties hereto.

Section 13.14. Entire Agreement.

         This Agreement, the Exhibits and Schedules hereto and the documents
specifically referred to herein and the Confidentiality Agreement constitute the
entire agreement, understanding, representations and warranties of the parties
hereto, and supersede all prior agreements, both written and oral, between Buyer
and Seller. All Exhibits and Schedules annexed hereto or referred to herein are
hereby incorporated in and made a part of this Agreement as if set forth in full
herein. Disclosure of any fact or item in any Schedule referenced by a
particular paragraph or Section in this Agreement shall, should the existence of
the fact or item or its contents be relevant to any other paragraph or Section,
be deemed to be disclosed with respect to that other paragraph or Section
whether or not any explicit cross-reference appears therein.

Section 13.15. Counterparts.

         This Agreement may be executed in multiple counterparts, each of which
shall be deemed an original, and all of which together shall constitute one and
the same instrument.

Section 13.16. Severability.

         If any term or other provision of this Agreement is invalid, illegal or
incapable of being enforced by any rule of law or public policy, all other
conditions and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the greatest extent possible.
