           (b)    Within one hundred twenty (120) days after the Closing Date,
Sellers shall notify Buyer of the actual amount as recorded on Sellers' books
and records for the Business of any items that were estimated in arriving at the
Estimated Purchase Price, as well as the prorations and adjustments required to
be made under Section 3.3.  Buyer may dispute any amount so determined by
Sellers, by written notice to Sellers within forty-five (45) days after receipt
of Sellers' notice.  If Buyer does not so dispute any item, the party owing the
difference between the Estimated Purchase Price and the Purchase Price shall pay
such difference to the other party within ten (10) days after the expiration of
such forty-five (45) day period, plus interest at 8.25% per annum on such amount
from the Closing Date to (but not including) the date of payment.  If Buyer
disputes the actual amount of any item, the undisputed amount plus interest at
8.25% per annum on such amount from the Closing Date to (but not including) the
date of payment shall be paid promptly by the owing party.  If such dispute
cannot be resolved within sixty (60) days after the giving of Buyer's notice
that there exists a disputed amount, then a nationally recognized independent
accounting firm mutually agreeable to Buyer and Citizens shall, upon written
notice from either Buyer or Citizens, resolve such dispute within sixty (60)
days after receipt of such notice.  The fees and expenses of such independent
accounting firm shall be allocated between Buyer and Sellers so that Sellers'
share of such fees and expenses shall be in the same proportion that the
aggregate amount of such remaining disputed amounts so submitted by Buyer to
such accounting firm that is unsuccessfully disputed by Buyer (as finally
determined by such accounting firm) bears to the total amount of such remaining
disputed amounts so submitted by Buyer to such accounting firm.  Any
determination by such independent accounting firm shall be binding and
conclusive upon the parties without further appeal therefrom.  Within ten (10)
days after the independent accounting firm shall have resolved such dispute, the
party owing the determined amount shall pay such determined amount to the other
party, plus interest at 8.25% per annum on such determined amount from the
Closing Date to (but not including) the date of payment.

     Section 3.3  Prorations and Adjustments as of the Closing Date.

           (a)    Buyer and Sellers agree that the following items relating to
the Assets and the Business shall be adjusted and allocated as of the Closing
Date, with Sellers to be responsible for and to receive the benefit of the same
for the period through and including the Closing Date and Buyer to be

item by item by Sellers and reflected on the certificate and supporting
documentation to be delivered to Buyer pursuant to Section 3.2(a) and finally

reasonable efforts shall include: (i) Buyer's assumption of the Contracts on the
terms set forth in this Agreement; and (ii) an obligation on the part of Buyer
to provide (A) a guaranty, letter of credit, bond or other surety instrument at
Closing in lieu of any surety instrument provided by Citizens to any beneficiary
in connection with the Business or the activities of LGSN or (B) if such
beneficiary refuses to accept such replacement surety instrument from Buyer, a
specific indemnity from Buyer to Citizens in respect of Citizens' surety
instrument.

     Section 6.3   Governmental Filings.

          (a)      HSR Act Filing.  Buyer and Citizens shall comply promptly
                   --------------
with the notice and reporting requirements of the HSR Act. Buyer and Citizens
shall comply substantially with any additional requests for information,
including requests for production of documents and production of witnesses for
interviews or depositions, made by the Antitrust Division of the United States
Department of Justice, the United States Federal Trade Commission or the
antitrust or competition law authorities of any other jurisdiction (the
"Antitrust Authorities"). Buyer and Citizens shall each exercise its
commercially reasonable efforts, and each shall cooperate fully with the other
to prevent the entry in any Proceeding brought by an Antitrust Authority or any
Governmental Body which would prohibit, make unlawful or delay the consummation
of the transactions contemplated by this Agreement.

          (b)      Other Regulatory Filings.  Buyer and Sellers will, as soon as
                   ------------------------
reasonably practicable following the execution of this Agreement, prepare and
file with each Governmental Body requests for such Consents as may be necessary
for the transfer of the Assets in accordance with, or as contemplated by, the
terms of this Agreement (including using commercially reasonable efforts to
prepare and file a joint application, in a mutually acceptable form, with the
LPSC by June 1, 2000).  Buyer and Sellers will use commercially reasonable
efforts to diligently pursue such Consents and will cooperate with each other in
seeking such Consents.  To this end, the parties agree to make available the
personnel and other resources of their respective organizations in order to
accomplish actions reasonably required by them to obtain all such Consents.  A
request in the parties joint application for a rate moratorium or for consent to
amortize Buyer's acquisition premium account shall be deemed not to be
inconsistent with the parties commercially reasonable efforts.

          (c)      Efforts.  Nothing contained in this Section 6.3 shall require
                   -------
Sellers or Buyer to institute or defend any legal or administrative Proceeding,
make any material payment or incur any

                                      30
<PAGE>

economic burden, dispose of any material asset or business or suffer any
material detriment, including any change in the applicable rates or tariffs of
the Business or the imposition of any other materially adverse term or condition
on the Business or the Assets.

     Section 6.4    Citizens Marks.   Buyer acknowledges and agrees that, as
between Buyer and Citizens, Citizens has the absolute and exclusive proprietary
right to all names, marks, trade names, trademarks and corporate symbols and
logos incorporating "Citizens", and "CZN" (collectively,  the "Citizens Marks"),
all rights to which and the goodwill represented thereby and pertaining thereto
are being retained by Citizens.  Within four (4) months after the Closing Date,
Buyer shall cease using any Citizens Mark and shall remove from the Assets any
and all Citizens Marks.  Thereafter, Buyer shall not use, any Citizens Mark in
connection with the sale of any products or services or otherwise in the conduct
of its businesses.  In the event that Buyer breaches this Section 6.4, Citizens
shall be entitled to specific performance of this Section 6.4 and to injunctive
relief against further violations, as well as any other remedies at law or in
equity available to Citizens.

     Section 6.5    Transition Plan.  Within thirty (30) days after the
execution date of this Agreement, Buyer shall deliver to Citizens a list of its
proposed representatives to a joint transition team, which shall include
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.  Citizens will add its
representatives 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 at least sixty (60)
days prior to the Closing Date, 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.  Transition services to be supplied by
Citizens under such transition plan shall be priced in accordance with inter-
company transfer practices consistent with those historically used for the
Business for a reasonable transition period not to exceed 120 days after the
Closing Date.  If requested by any party, the terms and conditions governing
such transition activities will be more fully set forth in a Transition
Agreement reasonably satisfactory to the parties.  Buyer and Citizens 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 120
days after the date of this Agreement.

     Section 6.6    Substitute Agreement. In the event that Sellers, after using
their best commercially reasonable effects, are unable to obtain each of the
Consents identified as items IV.F.1 through IV.F.5 of Schedule 5.3 within 120
days after the date of this Agreement, then promptly upon notice from Sellers to
Buyer, Citizens and Buyer will enter into a substitute agreement relating to the
sale by Citizens of the Division Assets and the capital stock of LGSN
substantially in the form attached as Exhibit 6.6 hereto.

     Section 6.7    Schedule of Easements and Interests.  Within 180 days
following the date of this Agreement (but in no event later than 60 days prior
to the Closing Date), Citizens shall deliver to Buyer a schedule, to be
identified as Schedule 6.7, which sets forth all Easements and ownership
interests in Real Property included in the Assets, together with such title
descriptions, recorded and unrecorded acts, and other information as shall be
customary in the State of Louisiana to identify and

                                      31
<PAGE>

convey such Easements and ownership interests. All material Easements that, as a
condition to their assignment, require Consent from the grantor thereof, shall
be so designated on Schedule 6.7.

     Section 6.8    Rhodes Security.  If at any time Sellers shall have any
financial obligation or liability with respect to the Rhodes Proceedings,
whether due to any Order of the LPSC or an appeal therefrom, that is materially
more than that which is secured by a bond, other surety instrument or other
collateral (including a standby letter of credit) previously provided by
Citizens (or if no such collateral has been previously provided), Citizens shall
promptly deliver to Buyer (or the appropriate Governmental Body, if required) a
bond, other surety instrument or other collateral reasonably acceptable to Buyer
(or, if agreement is not reached as to the form or substance of such bond or
surety instrument, Citizens shall deliver to Buyer a standby letter of credit
from Citibank, N.A., or other financial institution reasonably acceptable to
Buyer) fully securing in all material respects the unsecured amount of such
obligation or liability.  If at any time any bond, other security instrument or
other collateral held by Buyer in respect of the Rhodes Proceedings shall be
materially in excess of the amount of such obligation or liability, Buyer shall
cooperate with Citizens in reducing the amount of such collateral to the extent
of such excess, including the release of a surety instrument previously
delivered to Buyer in exchange for a substitute surety instrument in the amount
of such reduced obligation or liability.

     Section 6.9    Certain Proceedings.  Sellers shall defend the Proceedings
described in items II.2 and II.3 of Schedule 5.16 at their own expense, with
counsel of their own choosing.  Sellers shall promptly and diligently pursue to
a settlement or prosecute to a final conclusion the Proceeding described in item
II.2 of Schedule 5.16.  Prior to Closing, Buyer shall have the right to
intervene, at Buyer's expense, in the Proceedings listed in items II.2 and II.3
of Schedule 5.16 to protect its interests as the prospective buyer of the
Business, including any resolution of such Proceedings that Buyer believes may
adversely affect the Business or the Assets after the Closing.  If either
Proceeding listed in items II.2 and II.3 of Schedule 5.16 continues after the
Closing, Buyer shall take over the prosecution of such Proceeding, provided that
Sellers may continue to participate in such Proceeding, at Sellers' expense, to
protect their interests as the former operators of the Business with the right
to appeal either directly or through Buyer any decision adverse to Sellers.

     Section 6.10   Buyer's Insurance.  Buyer shall deliver at Closing a
schedule that identifies each material casualty and property insurance policy of
Buyer applicable to its business in Louisiana.

                ---------------------------------------------------------------
The LPSC shall have issued an Order approving the transactions contemplated

Business as operated on the date of this Agreement or on the other operations of
Buyer in the State of Louisiana as operated on the date of this Agreement; the
other terms and conditions of such Order shall not be materially adverse to

treatment requested by Buyer in the parties' joint application to the LPSC that

the State of Louisiana or to Buyer.  In addition, Sellers shall have obtained
all other Consents of Governmental Bodies and other Persons which are required

Order does not have to be a Final Order).  If such LPSC Order imposes any
financial obligation or liability (or any administrative obligation or liability
that could reasonably result in a financial obligation or liability) and such
obligation or liability shall not have been discharged or settled in full by
Citizens, then Citizens shall have delivered to Buyer (or to the appropriate
Governmental Body, if required) a bond or other surety instrument or other

promptly as practicable after the Closing such records (including customer and
employee records) necessary to own and operate the Business.

          (i)       No Material Adverse Change. Since the date of execution of
                    --------------------------
this Agreement, no Material Adverse Effect shall have occurred that has
continuing effect as of the Closing Date, it being agreed that no Order
resolving or other development in the Proceedings referenced in item I.5 or I.23

Section 7.2(a) with respect to Sellers' representations and warranties set forth
in Section 5.6(c)(v) or Section 7.2(b) with respect to Sellers' covenants in
Section 6.1(a)(iii) (as such covenant relates to such representations and
warranties) to have a Material Adverse Effect.

                                    CLOSING

     Section 8.1    Closing.  The closing of the purchase and sale of the Assets
(the "Closing") will take place at the offices of Fleischman and Walsh, L.L.P.,
1400 Sixteenth Street, N.W., Suite 600, Washington, D.C. 20036, on the last
calendar day of the month in which the conditions specified in Sections 7.1(d)
and 7.2(d) have been satisfied, unless another time, date and place is agreed to
in writing by the parties.  The date of the Closing is referred to in this
Agreement as the "Closing Date."  The transactions to be consummated on the
Closing Date shall be deemed to have been consummated as of 11:59 p.m. on the
Closing Date.  At the Closing the following events shall occur, each event being
deemed to have occurred simultaneously with the other events.

          (a)       Payment of Purchase Price.  Buyer will pay to Sellers an
                    -------------------------
amount equal to the Estimated Purchase Price by wire transferring such amount,
in lawful money of the United States of America in immediately available funds,
to such account(s) as Sellers shall have designated by notice to Buyer. If the
Closing Date is not a business day on which financial institutions are open and
operating, then on or before the last business day on which financial
institutions are open and operating before the Closing Date, Buyer shall deliver
the Estimated Purchase Price to Buyer's lead bank (the "Escrow Agent") in
immediately available funds in U.S. dollars, and each party shall deliver in
escrow to the other party's designated outside legal counsel the instruments and
other documents to be delivered by such party at the Closing. Upon receipt, the
Escrow Agent shall invest the Estimated Purchase Price in an interest-bearing
account mutually agreed upon by Sellers and Buyer. At Closing, upon
satisfaction of the conditions therefor, (i) Buyer shall sign and deliver to
Sellers a statement which confirms that the Closing has occurred and which
instructs the Escrow Agent to transfer to Sellers the funds representing the
Estimated Purchase Price, plus an amount representing the interest earned after
the Closing Date until the date the funds are transferred, to an account that
Sellers shall designate at least two (2) business days prior to the date the
funds are required to be transferred hereunder and (ii) each party shall sign
and deliver to the other party's designated outside legal counsel a statement
which confirms that Closing has occurred and which

                                      35
<PAGE>

authorizes the release to the other party of the instruments and other documents
previously delivered in escrow to such legal counsel by such party. The Escrow
Agent shall refund the balance to Buyer. If the Closing does not occur on the
appointed Closing Date, the funds shall be returned to Buyer, together with all
interest earned thereon, and all escrowed instruments and documents shall be
returned to the party who delivered them. The fees and expenses of Escrow Agent
shall be paid one-half by Sellers and one-half by Buyer.

          (b)       Other Related Documents. To the extent consistent with the
                    -----------------------
other provisions of this Agreement, Sellers (or the appropriate Affiliate of
Sellers) and Buyer shall execute and deliver acts of sale, conveyances,
certificates of title, bills of sale, assignment and assumption instruments and
other documents reasonably requested by a party that are necessary for the
transfer of the Assets to Buyer, or the assumption of the Assumed Liabilities by
Buyer, or the satisfaction of any applicable Legal Requirements relating
thereto, or which are customarily given in the State of Louisiana to accomplish
transfers of assets of the type involved; provided, however, that nothing in
this clause (b) shall obligate Sellers or any Affiliate of Sellers to execute or
deliver any document that affects, in a manner adverse to Sellers or Sellers'
liability to Buyer, or to Buyer or to Buyer's liability to Sellers, as expressed
herein; and provided also that all acts of sale with respect to parcels of Real
Property owned in fee simple shall be with all legal warranties by, through
and/or under the Seller, but not otherwise, with such warranty warranting title
to the property from the date such Seller acquired title to such property to the
Closing Date, subject to Permitted Encumbrances, and with full substitution and
subrogation in and to all rights and actions of warranty that such Seller has or
may have against all preceding owners and venders.

                                  ARTICLE IX
                                  TERMINATION

     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 Sellers and Buyer;

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

          (c)       By Buyer, upon and during the continuation of a breach in
any material respect of any of the representations and warranties of Sellers
contained herein or in the failure by Sellers 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 Sellers, provided that such breach
or failure is not cured by Sellers in a manner reasonably acceptable to Buyer
within 45 days of Sellers' receipt of a written notice from Buyer that such a
breach or failure has occurred;

          (d)       By Sellers, upon and during the continuation of a 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

                                      36
<PAGE>

is not cured by Buyer in a manner reasonably acceptable to Sellers within 45
days of Buyer's receipt of a written notice from Sellers that such a breach or
failure has occurred;

          (e)       By either party in writing if the Closing has not occurred
within twelve (12) months after the date of this Agreement; provided that if
Closing has not occurred within such period of time because the conditions
precedent to Closing set forth in Sections 7.1(d) and 7.2(d) have not been
fulfilled, then such period of time shall be automatically extended to August 1,
2001; or

          (f)       By Sellers or Buyer, as appropriate, if any Governmental
Body or other Person whose Consent is required to fulfill a condition precedent
to Closing set forth in Section 7.1(d) (with respect to Sellers) or in Section
7.2(d) (with respect to Buyer) has affirmatively indicated that such Consent
will not be given or will contain terms or conditions (or, if such Consent has
been obtained, contains terms or conditions) that, in the reasonable business
judgment of Sellers or Buyer, as appropriate, will result in a condition
precedent to Closing set forth in Section 7.1(d) (with respect to Sellers) or in
Section 7.2(d) (with respect to Buyer) not being satisfied.

     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 material condition to the performance of any other party or
to perform a material 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 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 any 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 such event shall any party be entitled to
receive any consequential, exemplary, punitive, or speculative damages.

<PAGE>

other authorized leave of absence which is scheduled to last not more than
thirty (30) business days after the Closing Date at the same wages or salary as

absence scheduled to last more than thirty (30) days where there is a legal or
contractual right to reinstatement, as of the date, if any, within one (1) year
from the Closing Date, on which such employee returns to active work, in
compliance with Buyer's return to work policies and practices, at the same wages
or salary as were in effect with Citizens immediately prior to the Closing Date.
Any such 070 Active Employee employed by Buyer as provided in this Section
10.1(a) is referred to herein as a "Transferred Employee".

          (b)       Prior to the execution date of this Agreement, Sellers have
delivered to Buyer a list of the persons who would have been Transferred
Employees had the Closing Date occurred on March 31, 2000, showing the following
information for each such person:  (i) the name of each employee; (ii) the name
of his or her current employer; (iii) his or her current base pay; (iv) his or
her hire date, any rehire date (if available) and years of service; (v) his or
her then-current position and job title; (vi) whether such employee is subject
to a collective bargaining agreement or represented by a labor organization and,
if so, the name of the union and local, (vii) whether such employee is on
authorized leave of absence scheduled to last more than thirty (30) days with a
legal or contractual right to reinstatement and the nature of such leave of
absence.  Sellers shall update such list as of the end of each calendar quarter
occurring between the execution date hereof and the Closing Date, in each case
assuming the Closing Date had occurred on such date, and shall deliver such
updated lists to Buyer within ten (10) days after the end of each such calendar
quarter.

     Section 10.2   Intentionally Omitted.

     Section 10.3   Cessation of Participation in Sellers' Plans; Bonuses. From
and after the Closing Date, Transferred Employees shall accrue no additional
benefits under any employee benefit plan, policy, program or arrangement of
Sellers or its Affiliates. Citizens shall on a pro rata basis or as otherwise
determined by Citizens in its sole discretion, pay any bonuses declared by
Sellers after the Closing Date that would have been payable to the Transferred
Employees had the Transferred Employees remained employed by Sellers or its
Affiliates throughout the calendar year in which the Closing Date occurs, in
accordance with the provisions of any policy, plan, practice or arrangement of
Sellers under which such bonus would have been paid.

     Section 10.4   Similarity of Benefit Packages.  As of the Closing Date,
and except as otherwise expressly provided in this Article X, Buyer shall
include each Transferred Employee in a benefit package providing benefits that
are identical to those provided by Buyer to its non-union gas utility employees
(which are deemed by Buyer and Seller to be in the aggregate substantially
similar to those provided by Sellers to such Transferred Employees).  Except as
otherwise expressly provided in this Article X, Buyer shall treat all service
and compensation credited to each such Transferred Employee as if such service
and compensation had been rendered to, and paid by, Buyer for all purposes of
eligibility and vesting of benefits but not for purposes of earning benefits
under Buyer's benefit plans, arrangements, and policies.

     Section 10.5   Defined Benefit Pension Plan.

          (a)       At least fifteen days prior to the Closing Date, Sellers
shall take any and all actions necessary to cease benefit accruals and fully
vest all Transferred Employees in their accrued benefits under the Citizens'

and assets for pension benefits accrued through the Closing Date by Transferred
Employees and retirees of the Business under Citizens' Pension Plan.

          (b)       As of the Closing Date, Buyer shall cause all Transferred
Employees who are otherwise eligible to be included in the Atmos Energy

that all Transferred Employees had under Citizens' Pension Plan for purposes of
such Employees' eligibility to participate, vesting, attainment of retirement
dates, eligibility for early retirement benefits under Buyer's Pension Plan and
entitlement to optional forms of payment.

     Section 10.6   401(k) Plan.

          (a)       Buyer shall take all action necessary to ensure that, as of
the Closing Date, it includes Transferred Employees who are otherwise eligible
in the Atmos Energy Corporation Employee Stock Ownership Plan and Trust (the
"Buyer's 401(k) Plan"). Buyer shall take all actions necessary to cause Buyer's
401(k) Plan to recognize the service that the Transferred Employees had in
Citizens' 401(k) Savings Plan (the "Citizens' 401(k) Plan") for purposes of
determining such Employees' eligibility to participate, vesting, attainment of
retirement dates and, if applicable, contribution levels and eligibility for
optional forms of benefit payments. Buyer shall cause the trustee of Buyer's
401(k) Plan to accept transfers and, to the extent legally permissible, direct
rollovers from Citizens' 401(k) Plan of the vested account balances of
Transferred Employees, including transfers of outstanding loan balances and
related promissory notes, subject to compliance with applicable law.

          (b)       Citizens shall vest Transferred Employees in their account
balances under Citizens' 401(k) Plan as of the Closing Date.

          (c)       Citizens shall direct the trustee of Citizens' 401(k) Plan
to transfer to the trustee of Buyer's 401(k) Plan in a trustee-to-trustee
transfer the account balances of the Transferred Employees under Citizens'
401(k) Plan with such transfer to consist of cash and the shares of Citizens'
stock attributable to the former LGS Savings and Investment Plans credited to
the accounts of each Transferred Employee; except that to the extent that the
account balances consist of outstanding loans, Citizens shall direct the trustee
of Citizens' 401(k) Plan also to transfer to the trustee of Buyer's 401(k) Plan
the promissory notes, payroll deduction authorizations for installment payments
and related documents evidencing such loans.

          (d)       After the transfer of assets and liabilities pursuant to
this Section, Buyer shall assume all liabilities for the benefits payable with
respect to the assets transferred with respect to the Transferred Employees
under Citizens' 401(k) Plan, and Citizens and Citizens' 401(k) Plan shall have
no liability for such benefits.

<PAGE>

          (e)  In connection with the transfer of assets and liabilities under
this Section, Citizens and Buyer shall cooperate in making all appropriate
filings, and providing all applicable notices, required by the IRC or ERISA.
Buyer shall deliver to Citizens a copy of Buyer's 401(k) Plan, and a copy of the
most recent determination letter from the IRS with respect to such Plan.  Buyer
will submit Buyer's 401(k) Plan to the IRS within the current remedial amendment
period for a determination that Buyer's Plan satisfies the requirements of the
Internal Revenue Code of 1986, as amended by the Uniformed Services Employment
and Reemployment Acts of 1999, the Small Business Job Protection Act of 1996,
the Taxpayer Relief Act of 1997 and the Internal Revenue Services Restructuring
and Reform Act of 1998.

     Section 10.7  Welfare Benefits.

          (a)  Buyer shall take all action necessary and appropriate to ensure
that, as of the Closing Date, Buyer includes the Transferred Employees to the
extent they are otherwise eligible in the  employee welfare benefit plans
(including retiree medical benefits) applicable to the other non-union gas
utility employees of Buyer (the "Buyer Welfare Plans").  For purposes of
determining eligibility to participate, and entitlement to benefits, in each
Buyer Welfare Plan, each Transferred Employee shall be credited with service,
determined under the terms of the corresponding welfare plans maintained by
Citizens on the Closing Date (hereinafter referred to collectively as the
"Citizens Welfare Plans").  Any restrictions on coverage for pre-existing
conditions, actively at work requirements, waiting periods, and requirements for
evidence of insurability (with respect to life insurance and long term
disability coverage) under the Buyer Welfare Plans shall be waived in the Buyer
Welfare Plans for Transferred Employees to the extent that such Transferred
Employees are covered by Citizens' Welfare Plans immediately prior to Closing,
and Transferred Employees shall receive credit under the Buyer Welfare Plans for
co-payments, payments under a deductible limit made by them, and for out-of-
pocket maximums applicable to them during the plan year of the Citizens Welfare
Plan in which the Closing Date occurs.  As soon as practicable after the Closing
Date, Citizens shall deliver to Buyer a list of the Transferred Employees who
had credited service under a Citizens Welfare Plan, together with each such
Transferred Employee's service, co-payment, deductible and out-of-pocket payment
amounts under each such plan.

          (b)  Buyer shall provide or cause to be provided retiree medical,
dental and life insurance benefits to each retiree of the Business identified in
Schedule 10.7 as updated as of the Closing Date (the "Retirees"), including
those Retirees who were retirees at the time Seller purchased LGS ("LGS
Retirees"), under the same or better terms and conditions as applied to such
Retirees immediately prior to the Closing Date, and shall provide or cause to be
provided retiree medical benefits to each Transferred Employee under the same
terms and conditions as otherwise applied to non-union gas utility employees
retiring from Buyer at the time such Transferred Employee retires from the
Buyer.  Citizens shall have no obligation or liability, contingent or otherwise,
to provide retiree medical, dental or life insurance benefits to any Retiree or
Transferred Employee on or after the Closing Date.  For purposes of this Section
10.7, a "grandfathered employee" is a Transferred Employee or Retiree who was at
least age 55 with at least 10 years of service as defined in the Citizens'
Pension Plan by December 31, 1997, and who either retired on or after August 1,
1997 and on or prior to December 31, 1997 or was an employee of Citizens on
December 31, 1997 and retires after December 31, 1997.  Schedule 10.7 identifies
each "grandfathered employee."  Buyer agrees that, in the event it ever
terminates or materially adversely modifies, those retiree medical, dental and
life insurance benefits covering LGS Retirees and

                                      40
<PAGE>

Retirees who are "grandfathered employees", their spouses and dependents from
those in effect immediately prior to the Closing Date or in the event it ever
terminates or materially adversely modifies those retiree medical benefits
provided to those Transferred Employees who are "grandfathered employees", their
spouses and dependents from those provided by Buyer to Buyer's non-union gas
utility employees immediately prior to the Closing Date, Buyer will indemnify
and hold harmless Sellers Indemnitees from any and all Loss in connection
therewith. Buyer's obligations under this Section 10.7(b) are subject to and
conditioned upon the truth and accuracy of the representation and warranty
contained in Section 5.13(f), and if such representation and warranty is
determined at any time not to be true and accurate, Buyer shall have no further
obligations under this Section 10.7(b).

     Section 10.8   Flexible Spending Accounts.  As soon as possible following
the Closing Date, Citizens shall transfer to Buyer's flexible benefits plan any
balances standing to the credit of Transferred Employees under Citizens'
flexible benefits plan as of the Closing Date.  Citizens shall provide to Buyer
prior to the Closing Date a list of those Transferred Employees who have
participated in the health or dependent care reimbursement accounts of Citizens,
together with their elections made prior to the Closing Date, with respect to
such account, and balances standing to their credit or debit as of the Closing
Date, and a statement of aggregate expenses reimbursed from the plan for each
Transferred Employee during the plan year.  Buyer agrees to administer such
accounts (consistent with the terms of the flexible benefits plan applicable to
Buyer's employees) such that Transferred Employees will be able to defer
compensation (in accordance with the terms of the applicable Buyer plan) and to
submit claims against such accounts within the time period permitted by
applicable law.

     Section 10.9   Employment Agreements.  Buyer shall assume all obligations
of each employment agreement to which Citizens  or its Affiliates is a party and
which covers any Transferred Employee immediately prior to the Closing Date
other than any such employment agreement that is identified as a Retained
Liability in Part III of Schedule 5.13.

     Section 10.10  Vacation/Time Off.  Citizens shall pay to Transferred
Employees any "banked" vacation credited to them on or prior to the Closing
Date.  On or after the Closing Date, each Transferred Employee shall be eligible
to participate in the Buyer's Time Off Policy.  Buyer shall take all actions
necessary to cause Buyer's Time Off Policy to recognize for all purposes under
said Policy the service, vacation and accrued sick time off that Transferred
Employees had with Citizens.  Citizens shall provide Buyer with a list of all
vacation, service and sick time off taken by each Transferred Employee and the
vacation, service and sick time off entitlement for each Transferred Employee
for the year including the Closing Date.

     Section 10.11  Severance.  In the event that Buyer terminates the
services of any Transferred Employee within twelve (12) months following the
Closing Date without cause, Buyer shall provide to any such Transferred Employee
severance or separation pay benefits in accordance with Schedule 10.11.  Buyer
will reimburse Seller at Closing for one-half of any severance or separation pay
benefits provided by Citizens to any Active Employee in connection with the
termination of such employee with which Buyer concurs at any time from the date
of this Agreement through and including the Closing Date.

                                      41

     Section 10.12  Health Care Continuation Coverage.  Citizens shall be
responsible for compliance with all requirements under Section 4980B of the Code
and Section 601 et seq. of ERISA (collectively "COBRA") with respect to any (a)
Transferred Employee and (b) family member of such Transferred Employee, in each
case who becomes a "qualified beneficiary" within the meaning of Section
4980B(g)(1) of the Code as a result of any "qualifying event" within the meaning
of Section 4980B(f)(3) of the Code which occurs on or prior to the Closing Date.
Citizens also shall remain responsible for compliance with COBRA with respect to
any (c) former employee of the Business or current employee of the Business who
is not a Transferred Employee and (d) family member of such former employee or
current employee, in each case who becomes a qualified beneficiary as a result
of any qualifying event, whether such event occurs on, prior to or after the
Closing Date.  Citizens covenants and agrees that Buyer shall have no liability
or responsibility for any of Citizens' COBRA obligations as described in this
Section 10.12.  Buyer shall be responsible for  compliance with COBRA with
respect to any (a) Transferred Employee and (b) family member of such
Transferred Employee, in each case who becomes a qualified beneficiary as a
result of any qualifying event which occurs after the Closing Date.  In the
event Seller shall fail or refuse to provide COBRA coverage as described in this
Section 10.12 to the Transferred Employees and their family members who become
qualified beneficiaries, Seller shall immediately so notify Buyer of such
failure or refusal and shall provide Buyer a list of (a) each person employed in
the Business within the 36 months immediately preceding the Closing Date and (b)
each such employee and all dependents of such employee, in each case who had
coverage at any time during such period and the dates during which he or she had
coverage during the 36 months immediately preceding the Closing Date.  For each
person who had coverage from any of Seller's group health plans and lost such
coverage at any time during the 36 months immediately preceding the Closing
Date, Seller shall provide to Buyer a copy of the COBRA notice and election
provided to each at the time of his/her qualifying event (as defined in IRC (S)
4980B(f)), copies of procedures used to notify each such qualified beneficiary
of the qualifying event, evidence of any election of COBRA coverage, evidence of
the reason for termination of each such COBRA coverage, evidence of any election
not to take COBRA, and evidence of COBRA premiums paid and any delinquency.  The
foregoing sentence shall apply only if Seller shall fail or refuse to provide
coverage to all Transferred Employees and family members who become qualified
beneficiaries, and shall not apply simply because any one or more individual
Transferred Employees and/or family members who become qualified beneficiaries
may not be provided with the appropriate COBRA coverage.

                                  ARTICLE XI
                                  TAX MATTERS

     Section 11.1   Purchase Price Allocation.  Prior to the Closing Date,
Buyer and Sellers shall use their good faith efforts to agree upon the
allocation (the "Allocation") of the Purchase Price for the Division Assets and
the Purchase Price for the LGSN Assets, the Assumed Liabilities and other
relevant items (including, for example, adjustments to the Purchase Price) to
the individual assets or classes of Citizens or LGSN, respectively, of assets
within the meaning of Section 1060 of the IRC.  If Buyer and Sellers agree to
such Allocation prior to Closing, Buyer and Sellers 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 Sellers 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 Sellers cannot agree to an Allocation, Buyer and Sellers covenant and
agree to file, and to cause their respective Affiliates to file, all Tax Returns
and

                                      42
<PAGE>

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 their respective 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 each Seller may, at its election prior to the Closing Date, direct
that all or a portion of the Purchase Price apportioned to its Assets be
delivered to a "qualified intermediary" (as defined in Treasury Regulation
Section 1.1031(k) - 1(g)(4)) as to enable its relinquishment of its Assets to
qualify as part of a like-kind exchange of property covered by Section 1031 of
the IRC, so long as the portion of the Purchase Price delivered to the qualified
intermediary in exchange for such Assets is consistent with Buyer's Allocation
under Section 11.1 with respect to such Assets. If a Seller so elects, Buyer
shall cooperate with such Seller (at no cost to Buyer) in connection with its
efforts to effect such like-kind exchange, which cooperation shall include
taking such actions as such Seller reasonably requests (but without Buyer being
required to incur any out-of-pocket costs in the course thereof) in order to
enable such 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 such
Seller may assign all or part of its rights and delegate all or part of its
obligations under this Agreement to a Person acting as a qualified intermediary
to qualify the transfer of the Assets as part of a like-kind exchange of
property covered by Section 1031 of the IRC, provided, however, that no such
assignment or delegation shall relieve Sellers of any of their obligations under
this Agreement nor shall legal title to any of the Assets transfer other than
directly from a Seller to Buyer.  Buyer and Sellers 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 Sellers in a manner
consistent with this Section 11.2; 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.  Buyer and Citizens shall each bear and
be responsible for paying one-half of any sales, use, transfer, documentary,
registration (other than any annual registration fees), and other similar
transfer type Taxes (including related penalties, additions to Tax and interest)
imposed by any Governmental Body with respect to the transfer of Assets
(including the Real Property) to Buyer ("Transaction Taxes"), regardless of
whether the ax authority seeks to collect such Taxes from Sellers or Buyer.
Citizens shall prepare all Tax filings related to any Transaction Taxes (other
than with respect to Real Property and motor vehicle title transfer and
registration, which shall be prepared by Buyer). Twenty (20) days prior to
making such filings, the filing party shall provide to the nonfiling party the
filing party's workpapers and proposed Tax Return for the nonfiling party's
review and approval.  The nonfiling party shall provide to the filing party
approval (which approval shall not be unreasonably withheld) or disapproval of
such workpapers and proposed Tax Return within ten (10) days of delivery by the
filing party. If the filing and nonfiling party are unable to agree on the
workpapers and proposed Tax Return, Buyer and Citizens shall engage a nationally
recognized independent accounting firm mutually satisfactory to both to prepare
the workpapers and proposed Tax Return, which preparation shall be binding and
conclusive on the Buyer and Sellers without further appeal therefrom, and which
fees and expenses shall be borne equally by the Buyer and Citizens. The filing
party shall 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, in each case subject to reimbursement

                                      43
<PAGE>

by the nonfiling party for one-half of such payments and expenses. Each party
shall give prompt written notice to the other 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, the filing party shall control
the defense of such Proceedings, but shall permit the nonfiling party to
participate in the defense of such proceeding and shall take all actions and
execute all documents required to allow such participation. Neither party shall
negotiate a settlement or compromise of any Transaction Taxes without the prior
written consent of the other, which consent shall not be unreasonably withheld.

     Section 11.4   Clearance Certificates.  Sellers shall provide Buyer with a
Tax clearance certificate or similar document(s) which may be required by any
state taxing authority in order to relieve Buyer of any obligation to withhold
any portion of the Purchase Price.

                                  ARTICLE XII
                             ENVIRONMENTAL MATTERS

     Section 12.1   Environmental Due Diligence.

          (a)       Right to Conduct Environmental Due Diligence. All
                    --------------------------------------------
environmental due diligence (including employee interviews and sampling of any
media or wastewater) conducted by Buyer shall be conducted in accordance with
this Section 12.1. All activities of Buyer regarding environmental due diligence
shall be conducted to minimize any inconvenience or interruption of the normal
use and enjoyment of the Business and the Assets.

          (b)       Delivery of Environmental Reports.  Buyer shall provide to
                    ---------------------------------
Sellers or to Sellers' counsel, copies of all reports, assessments and other
information composed or compiled by Buyer or Buyer's environmental consultant(s)
promptly following Buyer's receipt thereof. Buyer shall treat all such
information delivered to, or composed or compiled by, Buyer or Buyer's
environmental consultant(s) as Environmental Data in accordance with the
procedures of Section 12.1(c).

          (c)       Confidentiality of Environmental Data.  All audits, reports
                    -------------------------------------
and studies delivered to or prepared by Buyer and any other information
collected and generated as a result of Buyer's environmental due diligence
("Environmental Data") will be subject to the terms and conditions of the
Confidentiality Agreement, except as otherwise expressly provided in this
Section 12.1. Prior to the Closing, neither Buyer nor its environmental
consultant(s) shall disclose or release any Environmental Data without the prior
written consent of Sellers and all such information shall be kept strictly
confidential. Buyer expressly agrees that until the Closing, it will not
distribute the Environmental Data to any third party without Sellers' prior
written consent. After the Closing, Buyer agrees that it will not distribute the
Environmental Data to any third party without Citizens' prior written consent,
except as required by applicable Legal Requirements or by express provisions of
Buyer's corporate compliance program if Sellers are provided written notice at
least ten (10) days prior to such distribution, provided, however, that after
the Closing Date, Buyer may distribute the Environmental Data to any potential
purchaser of any of the Assets but only after first notifying Sellers.

                                      44
<PAGE>

          (d)   Environmental Consultants.  Buyer may retain one or more outside
                -------------------------
environmental consultants to assist in its environmental due diligence
concerning the Assets and shall notify Sellers of the environmental consultant
or consultants Buyer intends to retain.  Thereafter, Sellers shall have five (5)
days after receipt of such notification to notify Buyer in writing of Sellers'
objection (which must be for good cause) and substantiate the basis for that
objection.  If Sellers do not object for good cause and substantiate that
objection within said five (5) day period, Sellers shall be deemed to have
consented to Buyer's selection.

          (e)   Phase I Reviews.  Buyer may conduct, at its sole expense,
                ---------------
Phase I environmental assessment activities with respect to the Assets,
including reviewing existing environmental reports, correspondence, permits and
related materials regarding the Assets and all other Phase I activities as set
forth in the ASTM protocol regarding Phase I assessments. Any permitted Phase I
environmental assessment activities shall not include any sampling or intrusive
testing. All Phase I environmental assessment activities shall be conducted in
accordance with ASTM standards regarding Phase I assessments and shall be
completed within sixty (60) days after the date of execution of this Agreement.
Upon completion of such Phase I assessment activities, Buyer's environmental
consultant shall prepare and deliver to Buyer a written report with respect
thereto. All reports from Buyer's environmental consultants shall be delivered
to Sellers or Sellers' counsel within ninety (90) days after the execution of
this Agreement. Buyer shall notify Sellers in writing within ninety (90) days
after the date of execution of this Agreement if it has concluded, based on its
environmental due diligence, that the condition to Closing set forth in Section
7.2(a) will not be satisfied due to the discovery of such potential material
Environmental Liabilities unless environmental remediation of such potential
liabilities occurs prior to Closing. Buyer's failure to provide such notice by
such date shall preclude Buyer from subsequently declaring that the condition to
Closing set forth in Section 7.2(a) has not been satisfied based on the results
of Buyer's environmental due diligence, but shall not preclude the
indemnification or other rights of Buyer from Sellers in respect of the
Environmental Liabilities discovered by Buyer.

          (f)   Phase II Reviews.  Prior to Closing, Buyer may not conduct any
                ----------------
Phase II environmental assessment activities with respect to the Assets
(including the taking and analysis of soil, surface water and groundwater
samples, testing of buildings, drilling wells, taking soil borings and
excavating) without the prior written consent of Sellers, which consent may be
withheld, conditioned or delayed by Sellers in their sole discretion.

          (g)   Asbestos.  Buyer may conduct, at its sole expense, asbestos
                --------
survey activities with respect to the Assets, including reviewing existing
reports, correspondence and other related documents, inspecting individual sites
and collecting samples of suspected asbestos-containing materials. These
asbestos survey activities shall be completed within sixty (60) days after the
date of execution of this Agreement and shall be conducted in accordance with
the provisions of Section 12.1(e).

          (h)   Additional Due Diligence.  Notwithstanding the foregoing, if
                ------------------------
prior to Closing Citizens or LGSN receives notice of any Proceeding or
Threatened Proceeding arising under Environmental Laws or if Sellers otherwise
acquire Knowledge that is reasonably likely to require a change to Schedule
5.14, Sellers promptly shall notify Buyer of the same and Buyer may request that
Sellers authorize Buyer to conduct specific additional environmental due
diligence measures if and to the extent that such measures are required to
determine the extent of any potential Environmental

                                      45
<PAGE>

Liability relating thereto. Such authorization shall not be unreasonably
withheld, conditioned or delayed by Sellers. Any such additional environmental
due diligence shall be conducted at Buyer's sole expense.

          (i)      Indemnity for Due Diligence Activities.  Buyer hereby agrees
                   --------------------------------------
to indemnify and hold harmless Sellers, Sellers' Affiliates and their respective
officers, directors, employees, agents, successors and assigns from and against
any and all Losses with respect to personal injury or property damage arising
out of or in connection with any site visit by Buyer or its environmental
consultant(s) and resulting from an act or omission of Buyer or its
environmental consultant(s) in the course of its environmental inspections.

severally indemnify and hold harmless Buyer, its Representatives, Affiliates,

          (a)      any representations and warranties made by Sellers in or
pursuant to 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 Sellers in
the performance of their covenants, agreements, or obligations under this
Agreement required to be performed prior to Closing;

          (b)      any breach or default by Sellers in the performance of their
covenants, agreements, or obligations under this Agreement or any Related
Document delivered pursuant hereto required to be performed on or after Closing;

          (c)      any Retained Liabilities; and

          (d)      the Rhodes Proceedings.

     Section 13.2  Indemnification by Buyer.  From and after Closing and
subject to the other provisions of this Article XIII, Buyer shall indemnify and
hold harmless Sellers, their Representatives, Affiliates, successors and
permitted assigns (collectively, the "Sellers Indemnitees") from and against any
and all Losses arising out of or resulting from:

          (a)      any representations and warranties made by Buyer in or
pursuant to 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 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 any Related
Document delivered pursuant hereto required to be performed on or after Closing;
and

                                      46
<PAGE>

          (c)      any Assumed Liabilities and, except as to Retained
Liabilities and except to the extent Buyer is entitled (without regard to the
time or amount limitations provided in this Article XIII) to indemnification
under Section 13.1 with respect thereto, the operation of the Business after the
Closing Date.

     Section 13.3  Limitations on Liability.  Notwithstanding anything to the
contrary in this Agreement, the liability of Sellers and Buyer under this
Agreement and any documents delivered in connection herewith or contemplated
hereby shall be limited as follows:

          (a)      IN NO EVENT SHALL SELLERS BE LIABLE TO THE BUYER INDEMNITEES,
OR BUYER BE LIABLE TO THE SELLERS INDEMNITEES, FOR ANY CONSEQUENTIAL DAMAGES
(OTHER THAN FORESEEABLE DAMAGES INCLUDING FORESEEABLE DIMINUTION IN VALUE AND
FORESEEABLE LOST PROFITS), EXEMPLARY, PUNITIVE, OR SPECULATIVE DAMAGES;
provided, however, that if the Indemnified Party (as such term is hereafter
defined in Section 13.4(a)) is held liable to a third party for any of such
damages and the Indemnifying Party (as such term is hereafter defined in Section
13.4(a)), is obligated to indemnify the Indemnified Party for the matter that
gave rise to such damages, then the Indemnifying Party shall be liable for, and
obligated to reimburse the Indemnified Party for, such damages.

          (b)      Except as provided below, the representations, warranties,
covenants and agreements of Sellers and Buyer set forth in this Agreement shall
survive the Closing, and all representations, warranties, covenants and
agreements of Sellers and Buyer under this Agreement and the indemnities granted
by Sellers in Section 13.1 and by Buyer in Section 13.2 (except those that
survive without time limit) shall terminate at 5:00 p.m., local time in
Stamford, Connecticut, on the appropriate anniversary of the Closing Date or on
the expiration of the applicable statute of limitations (or extensions or
waivers thereof), as the case may be, as set forth below in this Section
13.3(b); provided, however, that, except in the case of indemnities that survive
without time limit, such indemnities shall survive with respect only to the
specific matters that are the subject of a proper Claim Notice delivered in good
faith in compliance with the requirements of this Section 13.3 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 or (B) the date on which the
matter described in such Claim Notice has otherwise reached final resolution,
provided that in each case the Indemnifying Party has fully satisfied any
indemnity obligation arising as a result of such resolution of such matter. In
no event, except in the case of indemnities that survive without time limit,
shall any amounts be recovered from Sellers under Section 13.1 or from Buyer
under Section 13.2, respectively, or otherwise for any matter for which a Claim
Notice is not delivered to Sellers or Buyer, as the case may be, prior to the
close of business on the applicable date set forth below.

                   (1)   All representations and warranties of Sellers and Buyer
contained in or made pursuant to this Agreement, and all covenants, agreements
or obligations of Sellers and Buyer contained in or made pursuant to this
Agreement that are required to be performed prior to Closing, and the related
indemnity obligations of Buyer and Sellers contained in Sections 13.1(a) and
13.2(a), respectively, shall survive Closing until and shall terminate on the
second anniversary of the Closing Date.

                                      47
<PAGE>

               (2)  The indemnity obligations of Sellers contained in Section
13.1(b) and 13.1(c) with respect to (i) Taxes shall survive until the expiration
of the applicable statute of limitations (or extensions or waivers thereof);
(ii) Environmental Liabilities shall survive until the fifth anniversary of the
Closing Date except with respect to Liabilities arising out of or relating to
non-compliance with a permit or authorization requirement of any Environmental
Law, which shall only survive until the second anniversary of the Closing Date;
(iii) the matters described in Sections 2.4(a), (c), (d), (e) (but only with
respect to Proceedings pending or Threatened as of the Closing Date), and (g)
shall survive without limitation as to time; (iv) the other matters described in
Section 13.1(b) shall survive without limitation as to time except for any
covenant as to title herein (the survival of which is addressed exclusively in
clause (vii) of this Section 13.3(b)(2)) and except in the event any specific
post-Closing covenant, agreement or obligation of Sellers under this Agreement
is expressly limited as to time, in which event such covenant, agreement or
obligation shall survive until the expiration of such specified time period; (v)
Retained Liabilities not otherwise addressed in clauses (i), (ii) and (iii) of
this Section 13.3(b)(2)) shall survive until the third anniversary of the
Closing Date; (vi) any warranty of title included in the acts of sale with
respect to parcels of Real Property owned in fee simple delivered pursuant to
Section 8.1(b) shall survive without time limit; and (vii) any covenant in this
Agreement as to title shall only survive until the second anniversary of the
Closing Date.

               (3)  The indemnity obligations of Sellers contained in Section
13.1(d) shall survive for an unlimited period of time. (The indemnity
obligations of Sellers described in this Section 13.3(b)(3) together with the
indemnity obligations of Sellers described in clauses (i), (iii) and (iv) of
Section 13.3(b)(2), and exclusive of the indemnity obligations of Sellers
described in clauses (ii), (v), (vi), and (vii) of Section 13.3(b)(2), are
collectively referred to hereinafter as the "Specified Indemnity Obligations.")

               (4)  The indemnity obligations of Buyer contained in Sections
13.2(b) and (c) shall survive for an unlimited period of time, except in the
event any post-Closing covenant, agreement or obligation of Buyer under this
Agreement is expressly limited as to time, in which event such covenant,
agreement or obligation shall survive until the expiration of such specified
time period.

               (5)  Notwithstanding the foregoing, the parties acknowledge that
Buyer shall be entitled to indemnification by Sellers for Losses incurred by
Buyer in respect of any intentional misrepresentation or omission or fraud by
Sellers without any time limitation (it being understood that the failure to
cure a breach shall not, by itself, be an intentional act or omission)
(hereinafter referred to as "Sellers' Fraud").

          (c)  Notwithstanding anything to the contrary in this Agreement,
Sellers shall not be required to indemnify the Buyer Indemnitees, or be
otherwise liable to the Buyer Indemnitees after the Closing with respect to this
Agreement, the transactions provided for herein or contemplated hereby or
Sellers' ownership or use of the Assets or operation of the Business on or
before the Closing Date for any Losses (other than Losses incurred by the Buyer
Indemnitees in respect of Specified Indemnity Obligations or Sellers' Fraud
(hereinafter referred to as "First-Dollar Losses")) until the Buyer Indemnitees
have suffered Losses (determined after giving effect to the provisions of
Section 13.3(f) and other than First-Dollar Losses) that are in excess of a
deductible in an amount equal to $3,000,000, after which point Sellers will be
obligated only to indemnify the

                                      48
<PAGE>

Buyer Indemnitees from and against further Losses in excess of such deductible.
Buyer shall be entitled to indemnification for all First-Dollar Losses without
regard to the foregoing limitation on Sellers' indemnification liability.

          (d)  Notwithstanding anything to the contrary in this Agreement,
Sellers shall not be required to indemnify the Buyer Indemnitees, or be
otherwise liable to the Buyer Indemnitees, after the Closing with respect to
this Agreement, the transactions provided for herein or contemplated hereby or
Sellers' ownership or use of the Assets or operation of the Business on or
before the Closing Date for any Losses (other than First-Dollar Losses) that are
in excess of an amount equal to $35,000,000.  Buyer shall be entitled to
indemnification for all First-Dollar Losses without regard to the foregoing
limitation on Sellers' indemnification liability.

          (e)  No right to indemnification under this Article XIII shall be
limited by reason of any investigation conducted by any party at any time or by
the decision by a party to complete the Closing.

          (f)  Buyer agrees to use its commercially reasonable efforts to give
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 be covered by 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 Sellers under
Section 13.1, 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.  Sellers agree to use
their commercially reasonable efforts to give written notice to the appropriate
insurance carrier(s) of any occurrences or circumstances which, in the judgment
of Sellers consistent with their customary risk management practices, appear
likely to be covered by one or more insurance policies of Sellers; and Buyer
agrees to cooperate with Sellers in connection with Sellers' investigation,
submission, prosecution, defense and settlement of claims under Sellers'
insurance policies, at Sellers' expense.  Any such notice shall be given in good
faith by Sellers without regard to the possibility of the limitation on
indemnification payments from Sellers under Sections 13(b) or (c), and shall be
processed by Sellers in good faith and in a manner consistent with its risk
management practices involving claims for which no such limitations are
available.  If at any time subsequent to the receipt by a Buyer Indemnitee of an
indemnity payment from a 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 Sellers an amount equal to the amount of
such recovery, less any out-of-pocket costs incurred by such Buyer Indemnitee
(or its Affiliates) in connection with claim preparation, pursuit and
settlement; provided that if such net recovery reduces the amount of Losses
actually incurred by the Buyer Indemnitees to an amount that is then below the
deductible amount set forth in Section 13.3(c), then the amount of such
reduction below such deductible amount shall again be available for Losses in
accordance with Section 13.3(c).

          (g)  Any limitation on indemnification provided in this Section 13.3
that is expressly applicable to any subsection or clause of Section 13.1 or 13.2
shall not be applicable to any indemnification as may be applicable under any
other subsection or clause of Section 13.1 or 13.2 to which such limitation is
not also expressly applicable.

                                      49
<PAGE>

          (h) Notwithstanding any language contained in any Related Document
(including deeds and other conveyance documents relating to the Real Property),
the representations and warranties of Sellers set forth in this Agreement will
not be merged into any such Related Document and the indemnification obligations
of Sellers, 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.

          (i) For the purposes of this Article XIII, once a determination has
been made that a specific breach of a representation, warranty, covenant or
agreement has occurred for purposes of the indemnification obligation hereunder,
the calculation of Losses with respect to such specific breach shall be made
without regard to any limitation or qualification as to materially set forth in
such representation, warranty, covenant or agreement.

          (j) Notwithstanding anything to the contrary in this Agreement,
Sellers shall not be required to indemnify the Buyer Indemnitees or otherwise be
liable to Buyer in respect of the Proceedings described in Section 2.4(e) for
any Losses of any Buyer Indemnitee arising out of or resulting from any
regulatory action affecting the regulatory treatment or requirements of Buyer
with respect to the Business after the Closing Date except to the extent a Buyer
Indemnitee is required by a Governmental Body to refund or otherwise credit
directly to customers revenues collected by Sellers on or prior to the Closing
Date, together with interest or any other amounts identified therewith.

     Section 13.4 Claims Procedure.

          (a) All claims for indemnification under Section 13.1 or 13.2, or any
other provision of this Agreement except as otherwise expressly provided in this
Agreement, shall be asserted and resolved pursuant to this Article XIII. Any
Person claiming indemnification hereunder is referred to as the "Indemnified
Party" and any Person against whom such claims are asserted hereunder is
referred to as the "Indemnifying Party."

          (b) Except in the case of the Rhodes Proceedings, in the event that
any Losses are asserted against or sought to be collected from an Indemnified
Party by a third party, said Indemnified Party shall with reasonable promptness
provide to the Indemnifying Party a Claim Notice. The obligation of the
Indemnifying Party to indemnify the Indemnified Party with respect to any such
Losses shall be reduced to the extent the Indemnifying Party is damaged by the
failure of the Indemnified Party to provide such notice. Any other claim
hereunder shall require the provision of a Claim Notice. The Indemnifying Party
shall have 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 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
defend all appropriate

                                      50
<PAGE>

Proceedings, and with counsel of its own choosing, which Proceedings shall be
promptly settled or prosecuted by it to a final conclusion; provided that no
such Proceeding may be settled without the prior written consent of the
Indemnified Party unless a full release is obtained by the Indemnified Party,
all amounts payable pursuant thereto are paid by the Indemnifying Party and the
settlement does not adversely affect the business or assets of the Indemnified
Party, including the Business or the Assets. 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. In the event that the Indemnifying Party fails to
notify the Indemnified Party within the Notice Period that it will defend
against such Losses, the Indemnified Party shall have the right to defend all
appropriate Proceedings, and with counsel of its own choosing, at the
Indemnifying Party's expense, which Proceedings may be settled (without consent
of the Indemnifying Party) or prosecuted by it to a final conclusion.

          (c) Sellers shall defend the Rhodes Proceedings at their own expense,
with counsel of their own choosing, which Sellers shall promptly and diligently
pursue to a settlement or prosecute to a final conclusion; provided that neither
of the Rhodes Proceedings may be settled without the consent of Buyer unless
reasonably concurrently therewith any financial obligations or liability payable
pursuant thereto are paid by Sellers or provision for payment is made in
accordance with any related Legal Requirements and this Section 13.4(c) or
Sections 6.8 or 7.2(d), as the case may be. If Buyer becomes obligated to pay
any financial compensation to the plaintiffs in the Rhodes Lawsuit, then
Citizens will pay such compensation in accordance with all applicable Legal
Requirements or deliver to Buyer (or to the Judicial District Court, Jefferson
Parish, Louisiana, if appropriate) a bond or other surety instrument reasonably
acceptable to Buyer fully securing payment of such compensation. Notwithstanding
the delivery of surety instruments pursuant hereto, Citizens shall remain liable
for, and shall pay when due, all obligations secured thereby. If Citizens fails
to pay any such obligations when due, and Buyer is required to pay, Buyer shall
be entitled to draw on such surety instruments in accordance with the terms
thereof. Upon satisfaction of all of Citizens' obligations secured by any such
surety instrument, Buyer shall return such surety instrument to Citizens.
Citizens' obligation to indemnify the Buyer Indemnitees in respect of the Rhodes
Proceedings shall be paid without any right of setoff and notwithstanding any
failure of Buyer to perform any of its obligations under the Agreement or any
other agreement as instrument delivered pursuant hereto.

          (d) 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.

          (e) With regard to third party claims for which Buyer is or Sellers
are entitled to indemnification under Section 13.1 or 13.2, but subject to
Section 13.4(c), 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. Notwithstanding the
foregoing but subject to Section 13.4(b) and (c), and provided that there is no
dispute as to the applicability of

                                      51
<PAGE>

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 13.5 Exclusive Remedy. Except as otherwise provided in Article VI,
Article X and this Section 13.5, the rights, remedies and obligations of the
Buyer Indemnitees and the Sellers Indemnitees set forth in this Article XIII
will be the exclusive rights, remedies and obligations of such Persons after the
Closing with respect to this Agreement, the transactions provided for herein or
contemplated hereby or Sellers' ownership of the Assets or operation of the
Business on or before the Closing Date, except for Sellers' Fraud.
Notwithstanding the foregoing, with respect to Environmental Liabilities and
Retained Liabilities referred to in Section 13.3(b)(2)(v), the indemnification
provisions set forth in this Article XIII are not exclusive and shall be in
addition to any other remedies any Buyer Indemnitee may have pursuant to
statutory or common law, but subject to the limitations provided in Section
13.3(a), (c) and (d).

     Section 13.6 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.

                                  ARTICLE XIV
                              GENERAL PROVISIONS

     Section 14.1 Expenses. Except as otherwise specifically provided herein,
each party will pay all costs and expenses of its performance of and compliance
with this Agreement, except (i) Buyer will pay all real estate and motor vehicle
title transfer recording fees, and (ii) all Transaction Taxes relating to the
transfer of real property and motor vehicles will be shared equally between
Buyer, on the one hand, and Sellers, on the other hand.

     Section 14.2 Notices. All notices, requests and other communications
hereunder shall be in writing and shall be deemed to have been given upon
receipt if either (a) personally delivered, (b) sent by prepaid first class
mail, and registered or certified and a return receipt requested (c) sent by
overnight delivery via a nationally recognized carrier or (d) by facsimile with
completed transmission acknowledged:

     Section 14.3 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; 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 in writing 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, (a) Buyer may assign this Agreement (or any right
or obligation hereunder), without the prior written consent of Sellers, to any
direct or indirect wholly-owned subsidiary of Buyer provided such subsidiary
assumes in writing all of the duties and obligations of Buyer (or such
obligation) hereunder (provided that no such assignment by Buyer shall in any
way operate to enlarge, alter or change any obligation due to Sellers or relieve
Buyer of its obligations hereunder if such subsidiary fails to perform such
obligations, with the understanding that Buyer shall be jointly and severally
liable with such subsidiary for any nonperformance of such obligations
hereunder); and (b) Sellers may assign all or part of its rights or delegate all
or part of their duties under this Agreement, without the prior written consent
of Buyer, to a qualified intermediary chosen by Sellers to structure all or part
of the transactions contemplated hereby as a like-kind exchange of property
covered by Section 1031 of the IRC, (provided that no such assignment by Sellers
shall in any way operate to enlarge, alter or change any obligations due to
Buyer or relieve Sellers of their obligations hereunder if such qualified
intermediary fails to perform such obligations, with the understanding that
Sellers shall be jointly and severally liable with such qualified intermediary
for any nonperformance of Sellers' obligations hereunder).

     Section 14.4 Successor Bound. Subject to the provisions of Section 14.3,
this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns.

     Section 14.5 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 THAT WOULD APPLY ANY
OTHER LAW.

     Section 14.6 Dispute Resolution. Except as otherwise provided in Sections
3.3(b), 6.4 and 11.3, and this Section 14.6, 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

                                      54
<PAGE>

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 by the parties, the representatives may utilize
other alternative dispute resolution procedures such as mediation (including
through a mediator upon whom the parties mutually agree or selected or
designated by the Washington, DC office of the American Arbitration Association)
to assist in the negotiations. Buyer, on the one hand, and Sellers, on the other
hand, shall bear one-half of the expenses of any such mediator. Discussions and
correspondence among the parties' representatives for purposes of these
negotiations 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 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 arbitration shall
take place in Washington, D.C. The arbitration hearing shall be commenced within
60 days of such party's demand for arbitration. The arbitrator shall have the
power to and will instruct each party to produce evidence through discovery (i)
that is reasonably requested by the other party to the arbitration in order to
prepare and substantiate its case and (ii) the production of which will not
materially delay the expeditious resolution of the dispute being arbitrated;
each party hereto agrees to be bound by any such discovery order. The arbitrator
shall control the scheduling (so as to process the matter expeditiously) and any
discovery. The parties may submit written briefs. At the arbitration hearing,
each party may make written and oral presentations to the arbitrator, present
testimony and written evidence and examine witnesses. No party shall be eligible
to receive, and the arbitrator shall not have the authority to award, exemplary
or punitive damages. The arbitrator shall rule on the Dispute by issuing a
written opinion within 30 days after the close of hearings. 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 submitting and
presenting its position with respect to any Dispute to the arbitrator; 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 submitting and presenting its position, as the arbitrator shall
reasonably determine to be fair under the circumstances. Each party to the
arbitration 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 14.6 and
(ii) if any party, as part of a Dispute, seeks injunctive relief or any other
equitable remedy, including specific enforcement, then such party shall be
permitted to seek such injunctive or equitable relief in any federal or state
court or competent jurisdiction before, during or after the pendency of a
mediation or arbitration proceed under this Section 14.6. Each of the parties
irrevocably and unconditionally submits, for itself and its property, to the
nonexclusive jurisdiction of the United States District Court for the District
of Delaware and any state court sitting in the State of Delaware, and any
appellate court therefrom, in any action or proceeding permitted by this Section
14.6. Each of the parties hereby irrevocably consents to service of process by
registered or certified mail to the address provided for notices in Section
14.2. Nothing in this Agreement will affect the right of any party to this
Agreement to serve process in any other manner permitted by law.

     Section 14.7 Cooperation. Except as otherwise provided herein, 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 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 14.8 Construction of Agreement. The terms and provisions of this
Agreement represent the results of negotiations between Buyer and Sellers, 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 Sellers 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 14.9  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 14.10 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 14.11 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.

     Section 14.12 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 14.13 Amendment. This Agreement may be amended only by an
instrument in writing executed by duly authorized officers of the parties
hereto.

     Section 14.14 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 Sellers. 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 such fact or item or its contents be expressly or obviously
related 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 14.15 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 14.16 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

                                      57

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.
