     Section 2.2    Determination of Adjustment Amount and Preclosing Seller

             2.2.1  At least 12 Business Days prior to the Closing Date, Buyer

closing statement (the "Estimated Closing Statement") that shall set forth the
Sellers' best estimate of the Adjustment Amount (the "Estimated Adjustment
Amount"), if any, including a calculation of such Estimated Adjustment Amount

                                       27
<PAGE>   35
pay the Fixed Purchase Price plus the Estimated Adjustment Amount to Genco at

          2.2.2  At any time from the date on which Buyer shall have delivered
the Preclosing Seller Breach Amount Statement to the Sellers until the 30th day
after the Closing Date, the Sellers may object in writing to the estimated
Preclosing Seller Breach Amount or any other information included in the
Preclosing Seller Breach Amount Statement, which objection should include a
description, in reasonable detail, of the basis for such objection. If Sellers
so object, the parties shall attempt to resolve such dispute by negotiation. If
the parties are unable to resolve such dispute within ten (10) Business Days of
receipt by Buyer of any objection by the Sellers, such dispute shall be
submitted to final and binding arbitration before J*A*M*S/ENDISPUTE, or its
successor, pursuant to the United States Arbitration Act, 9 U.S.C. Sec. 1 et
seq. Any party may commence the arbitration process called for in this
Agreement by filing a written demand for arbitration with J*A*M*S/ENDISPUTE,
with a copy to the other parties. The arbitration will be conducted in
accordance with the provisions of J*A*M*S/ENDISPUTE's Comprehensive Arbitration
Rules and Procedures in effect at the time of filing of the demand for
arbitration. The parties will cooperate with J*A*M*S/ENDISPUTE and with one
another in selecting an arbitrator from J*A*M*S/ENDISPUTE's panel of neutrals,
and in scheduling the arbitration proceedings. The arbitrator shall be
instructed to make a final determination with respect to the submitted dispute
within sixty (60) days of the date of the appointment. The arbitrator shall
consider only the alleged breaches described in the Preclosing Seller Breach
Amount Statement and in any supplement thereto submitted in writing by Buyer to
the Sellers on or prior to the Closing Date (which supplement, if any, shall
contain the same type

                                       28

<PAGE>   36
of information required to be included in the Preclosing Seller Breach Amount
Statement with respect to any  alleged breaches described in such supplement),
which breaches may only be with respect to the matters specified in the
definition of Preclosing Seller Breach Amount set forth in this Agreement. The
Sellers may object to any supplement provided by Buyer in writing prior to the
30th day after the Closing Date, which objection should include a description,
in reasonable detail, of the basis for any such objection. The arbitrator shall
determine the amount of damages, if any, that constitute the Preclosing Seller
Breach Amount in accordance with the definition of Preclosing Seller Breach
Amount set forth in this Agreement. In no event may the amount of the Preclosing
Seller Breach Amount exceed the estimate of the Preclosing Seller Breach Amount
included in the Preclosing Seller Breach Amount Statement and any supplement
thereto submitted by Buyer to the Sellers in accordance with this Section 2.2.2.
The final determination of the Preclosing Seller Breach Amount resulting from
such arbitration shall be final and binding on the parties hereto. The parties
covenant that they will participate in the arbitration in good faith. The
provisions of this Section 2.2.2 may be enforced by any court of competent
jurisdiction.

     2.2.3  In the event that the Preclosing Seller Breach Amount as determined
pursuant to Section 2.2.2 (whether by arbitration or by settlement of the
parties after the Closing), if any, is less than the estimate of the Preclosing
Seller Breach Amount, if any, included in the Preclosing Seller Breach Amount
Statement and any supplement thereto submitted by Buyer to the Sellers in
accordance with Section 2.2.2, then Buyer shall pay to Genco, no later than
five (5) Business Days after such determination pursuant to Section 2.2.2, by
wire transfer of immediately available funds to an account designated by Genco,
the amount

                                       29
<PAGE>   37
of such difference, plus interest on such amount from and including the Closing
Date to the date of payment at an annual rate of 18%. In addition, in the event
that the estimate of the Preclosing Seller Breach Amount, if any, included in
the Preclosing Seller Breach Amount Statement (and any supplement thereto
submitted by Buyer to the Sellers in accordance with Section 2.2.2) is more than
118% of the Preclosing Seller Breach Amount determined pursuant to Section
2.2.2) (whether by arbitration or by settlement of the parties after the
Closing), then Buyer shall also include in such payment to Genco the fees and
expenses (including reasonable legal and accounting fees and expenses) incurred
by the Sellers in connection with the determination of the Preclosing Seller
Breach Amount pursuant to Section 2.2.2 (whether by arbitration or by settlement
of the parties after the Closing).

     2.2.4     Within ninety (90) days following the Closing Date, the Sellers
shall prepare and deliver to Buyer a final closing statement (the "Post-Closing
Statement") that shall set forth the amount of the Adjustment Amount (other than
the Preclosing Seller Breach Amount). The Post-Closing Statement shall include
(i) the Opening Balance Sheet, expanded to include financial statement
footnotes, and (ii) the Closing Balance Sheet. The Sellers shall provide Buyer
and Buyer's independent auditors with copies of, or access to, records and other
information that Buyer may reasonably request with respect to the information
set forth on the Post-Closing Statement (other than the Preclosing Seller Breach
Amount). For purposes of the Post-Closing Statement, the values of fuel
inventories and materials and supplies inventories on the Closing Balance Sheet
will be determined after physical inventory observations, performed in
accordance with normal and customary industry practices, performed on or about
the Closing

                                       30
<PAGE>   38
Date, at Buyer's cost, utilizing inventory valuation methods consistent with
those used on the Opening Balance Sheet.

     2.2.5  Within thirty (30) days following the delivery of the Post-Closing
Statement by the Sellers to Buyer, Buyer may object to the Adjustment Amount
(other than the Preclosing Seller Breach Amount) in writing. If Buyer so objects
to the Adjustment Amount, the parties shall attempt to resolve such dispute by
negotiation. If the parties are unable to resolve such dispute within thirty
(30) days of any objection by Buyer, the parties shall appoint the Independent
Accounting Firm, and shall instruct such firm, at Sithe's and Buyer's joint
expense, to review the calculation of the Adjustment Amount (other than the
Preclosing Seller Breach Amount) and determine the appropriate amount of the
Adjustment Amount (other than the Preclosing Seller Breach Amount), in
accordance with this Agreement, within thirty (30) days of such appointment. The
parties agree to cooperate with the Independent Accounting Firm and provide it
with such information as it reasonably requests to enable it to make such
determination. The finding of such Independent Accounting Firm shall be binding
on the parties hereto.

     2.2.6  Upon final determination of the Adjustment Amount (other than the
Preclosing Seller Breach Amount) pursuant to Section 2.2.5, whether by agreement
of the parties or as otherwise provided above, and regardless of whether the
Preclosing Seller Breach Amount has been finally determined, (a) if the
Adjustment Amount (assuming for this purpose that Preclosing Seller Breach
Amount is zero) is more than the Estimated Adjustment Amount (assuming for this
purpose that Preclosing Seller Breach Amount is zero), Buyer shall pay such
difference to Genco and (b) if the Adjustment Amount (assuming for this purpose
that Preclosing


                                       31
<PAGE>   39
Seller Breach Amount is zero) is less than the Estimated Adjustment Amount
(assuming for this purpose that Preclosing Seller Breach Amount is zero), Genco
shall pay such difference to Buyer, in either case, no later than five (5)
Business Days after such determination, by wire transfer of immediately
available funds to an account designated by the payee.

     2.2.7  Notwithstanding anything else in this Agreement to the contrary, (a)
in no event shall the Closing Balance Sheet or the calculation of Net Working
Capital include any accrual, reserve or liability with respect to any matter
included in the Preclosing Seller Breach Amount in excess of the accrual,
reserve or liability with respect thereto included in the Opening Balance Sheet,
(b) in no event shall any accrual, reserve or liability be included on the
Closing Balance Sheet or in the calculation of Net Working Capital with respect
to any matter disclosed in Section 3.2, 3.3, 3.6, 3.7, 3.8, 3.11, 3.12, 3.13,
3.14, 3.15, 3.17, 3.18, 3.19, 3.20 or 3.21, including any disclosure schedule
relating to any of the foregoing Sections (except (i) to the extent that an
accrual, reserve or liability with respect to such matter was included on the
Opening Balance Sheet, in which case no adjustment shall be made to such
accrual, reserve or liability for purposes of the Closing Balance Sheet and (ii)
for accruals for third party trade payables and accrued expenses incurred in the
ordinary course of business through the Closing Date) and (c) there shall be no
accrual, reserve or liability on the Closing Balance Sheet or in the calculation
of Net Working Capital with respect to any event or matter which gave rise to or
was part of a Material Adverse Effect.

delivery of

<PAGE>   40
substitute letters of credit or other security for each of the Terminated
Obligations in form and substance satisfactory to the beneficiary of each such
Terminated Obligation and use reasonable efforts to deliver to the Sellers
releases with respect to all Terminated Obligations as soon as reasonably
practicable. If Buyer is unable to effect any such substitution on or prior to
the Closing Date, Buyer will also indemnify and hold harmless each Seller from
and against any liabilities, claims, demands, judgments, losses, costs, damages
or expenses from and after the Closing Date that such Seller may sustain,
suffer or incur and that result from or arise out of or relate to that
Terminated Obligation until such time as substitutions of all such Terminated
Obligations are effected and releases thereto have been obtained; provided that
Buyer shall continue to use reasonable efforts to effect such substitution at
all times after the Closing Date with respect to the Terminated Obligations
until such time when the substitution of all Terminated Obligations has been
effected. The Sellers shall cooperate with and use reasonable efforts to assist
Buyer in obtaining any such releases; provided that none of the Companies, any
Subsidiary of any Company, any Seller or any Affiliate of any Seller shall be
obligated to seek any waiver or consent from any issuer of any Terminated
Obligation; and provided further, that the failure of either Seller to perform
its obligations in this Section shall not constitute an event that would, by
itself, give rise to any claim by Buyer or right of Buyer to terminate this
Agreement.

     Section 2.4 Senior Credit Facility and BECO Facility. On or prior to the
Closing Date, the Sellers shall, with respect to each of the Senior Credit
Facility and the BECO Facility, either (i) obtain consent of the lenders under

follow clause (ii), the Sellers and Buyer shall cooperate with one another to
arrange mutually satisfactory arrangements for the payment of the Aggregate
Purchase Price to assure that the outstanding obligations referred to in such
clause (ii) are discharged.

or in the aggregate, would have a Material Adverse Effect, (iv) liabilities or

any Company or Sithe or any Affiliate of Sithe, at law or in equity, or before

Subsidiary of any Company or (b) any Acquired Assets, which (in the case of (a)
or (b) above), if determined adversely to any Company or any Subsidiary of any
Company or Sithe or any Affiliate of Sithe, would reasonably be expected to

of the preceding sentence, no representation is made with respect to (i) any
proceeding before any Governmental Authority initiated by any Company or any
Subsidiary of any Company in which any Company or any such Subsidiary of any
Company is an applicant for any Permit or Environmental Permit, to the extent

intervener, and the subject matter of such intervention is of general
applicability to similarly-situated parties. Neither any Company nor any
Subsidiary of any Company is in default with respect to any order, writ,
injunction or decree known to or served upon such entity of any Governmental
Authority except for defaults which would not have, individually or in the
aggregate, a Material Adverse Effect.

Except as disclosed on Schedule 3.6, neither any Company nor any Subsidiary of
any Company has received any notification that it is in violation of any such
Permits and Environmental Permits except notifications of violations which would
not have, individually or in the aggregate, a Material Adverse Effect. Each

the execution by such Financing Parties and each such representative of a
confidentiality agreement with the Sellers in form and substance consistent with
the Confidentiality Agreement; provided, however, the failure of either Seller
to perform its obligations in this sentence shall not constitute a breach of

inconsistent with, or fail to take any action necessary for, the validity of the

at its own expense all other Tax Returns of the Companies and their
Subsidiaries. If either Buyer, on the one hand, or either Seller, on the other
hand, may be liable for any material portion of the Tax payable in connection
with any Tax Return to be filed by the other, the party responsible under this
Section 6.4.2 for filing such return (the "Preparer") shall prepare and deliver
to the other party (the "Payor") a copy of such return and any schedules, work
papers and other documentation then available that are relevant to the
preparation of the portion of such return for which the Payor is or may be
liable hereunder not later than 30 days before the Due Date (as defined in
Section 6.4.12 of this Agreement). The Preparer shall not file such return until
the earlier of either the receipt of written notice from the Payor indicating
the Payor's consent thereto, or the Due Date. The Payor shall have the option of
providing to the Preparer, at any time at least 15 days prior to the Due Date,
written instructions as to how the Payor wants any, or all, of the items for
which it may be liable reflected on such Tax Return. The Preparer shall, in
preparing such return, cause the items for which the Payor is liable hereunder
to be reflected in accordance with the Payor's instructions (unless, in the
opinion of nationally recognized tax counsel to the Preparer, complying with the
Payor's instructions would likely subject the Preparer to any criminal penalty
or to civil penalties) and, in the absence of having received such instructions,
in accordance with past practice.

     If the Preparer fails to satisfy its obligations pursuant to this Section
6.4.2, the Payor shall have no obligation to indemnify the Preparer for any
Taxes which are reflected on any such Tax


                                       71
<PAGE>   79
Return if and to the extent the Payor was actually prejudiced by such failure,
and shall retain any and all remedies it may otherwise have which arise out of
such failure.

          6.4.3  Transfer Taxes.

               6.4.3.1  Sales and Real Property Taxes. All sales and use and
real property transfer taxes incurred in connection with this Agreement and
the transactions contemplated hereby shall be borne by Buyer, and Buyer at its
own expense shall file, to the extent required by applicable laws and
regulations, all necessary Tax Returns and other documentation with respect to
all such transfer or sales and use taxes, and, if required by applicable law,
Buyer shall cause the Companies and their Subsidiaries to join the execution of
any such Tax Returns or other documentation.

               6.4.3.2  Other Transfer Taxes. All excise, transfer (excluding
real property transfer or gains taxes and excluding sales and use taxes),
stamp, documentary, filing, recordation and other similar taxes (excluding real
property transfer or gains taxes and excluding sales and use taxes), together
with any interest, additions or penalties with respect thereto and any interest
in respect of such additions or penalties, resulting directly from the sale and
transfer by the Sellers to Buyer of the Mid-Atlantic Stock and the LLC
Interests (the "Other Transfer Taxes"), shall be borne by Buyer.
Notwithstanding Section 6.4.2 of this Agreement, which shall not apply to Tax
Returns relating to Transfer Taxes, any Tax Returns that must be filed in
connection with Transfer Taxes shall be prepared and filed when due by Buyer,
and Buyer will use its reasonable efforts to provide such Tax Returns to the
Sellers at least 10 days prior to the Due Date for such Tax Returns.

          6.4.4  Indemnification.

                 6.4.4.1  Sellers' Indemnification of Buyer. The Sellers shall
indemnify Buyer from, against and in respect of any Taxes imposed on any
Company or any Subsidiary of a Company with respect to any taxable period, or
portion thereof, ending on or before the Closing Date; provided, however, that
with respect to Northeast Management, the Sellers shall have no obligation to
indemnify Buyer for taxes with respect to any taxable period or portion thereof
ending on or before November 24, 1999.

                 6.4.4.2  Buyer's Indemnification of the Sellers. The Buyer
shall indemnify the Sellers from, against and in respect of any liability of
the Sellers or their Subsidiaries for (A) any Taxes imposed on any Company or
any Subsidiary of a Company with respect to any taxable period, or portion
thereof, beginning on or after the Closing Date; and (B) any Transfer Taxes for
which Buyer is liable pursuant to Section 6.4.3 hereof.

          6.4.5  Computation of Tax Liabilities.

                 6.4.5.1  Proration of Taxes and Earnings and Profits. To the
extent permitted by law or administrative practice, the taxable years of each
Company and each Subsidiary of each Company shall end on and include the
Closing Date. Whenever it is necessary to determine the liability for Taxes, or
the earnings and profits, of any Company or any Subsidiary of a Company for a
portion of a taxable year or period that begins before and ends after the
Closing Date, the determination of the Taxes or the earnings and profits for
the portion of the year or period ending on, and the portion of the year or
period beginning after, the Closing Date shall be determined by assuming that
the


                                       73
<PAGE>   81
taxable year or period ended on and included the Closing Date, except that
exemptions, allowances or deductions that are calculated on an annual basis and
annual property taxes shall be prorated on the basis of the number of days in
the annual period elapsed through the Closing Date as compared to the number of
days in the annual period elapsing after the Closing Date.

                 6.4.5.2  Standalone Basis. Whenever it is necessary to
determine the liability of any Company or any Subsidiary of a Company for
Taxes, such liability shall be computed as if such Company or such Subsidiary
of a Company was not a member of Sithe's or Genco's consolidated, affiliated,
combined or unitary group for Tax purposes.

          6.4.6  Contest Provisions.

                 6.4.6.1  Notification of Contests. Each of Buyer, on the one
hand, and the Sellers, on the other hand (the "Recipient"), shall notify the
Vice President - Taxes or chief tax officer of the other party in writing
within 45 days of receipt by the Recipient of written notice of any pending or
threatened audits, adjustments or assessments (a "Tax Audit") which are likely
to affect the liability for Taxes of such other party. If the Recipient fails
to give such prompt notice to the other party, it shall not be entitled to
indemnification for any Taxes arising in connection with such Tax Audit if and
to the extent that such other party is actually prejudiced by such failure to
give notice.

                 6.4.6.2  Which Party Controls.

                 6.4.6.2.1  Sellers' Items. If such Tax Audit relates to any
taxable period, or portion thereof, ending on or before the Closing Date or for
any Taxes for


                                       74
<PAGE>   82
which the Sellers are liable in full hereunder, the Sellers shall at their
expense control the defense and settlement of such Tax Audit.

     6.4.6.2.2.  Buyer's Item.  If such Tax Audit relates to any taxable period,
or portion thereof, beginning on or after the Closing Date or for any Taxes for
which Buyer is liable in full hereunder, Buyer shall at its expense control the
defense and settlement of such Tax Audit.

     6.4.6.2.3.  Combined and Mixed Items.  If such Tax Audit relates to Taxes
for which both the Sellers and Buyers are liable hereunder, to the extent
practicable such Tax Items (as defined in Section 6.4.12 of this Agreement) will
be distinguished and each party will control the defense and settlement of those
Taxes for which it is so liable. If such Tax Audit relates to a taxable period,
or portion thereof, beginning before and ending after the Closing Date and any
Tax Item cannot be identified as being a liability of only one party or cannot
be separated from a Tax Item for which the other party is liable, the party
which has greater potential liability for those Tax Items that cannot be so
attributed or separated (or both) shall control the defense of the Tax Audit,
provided that such party defends the items as reported on the relevant Tax
Return and provided further that no such matter shall be settled without the
written consent of both parties, not to be unreasonably withheld.

     6.4.6.2.4.  Participation Rights.  Any party whose liability for Taxes may
be affected by a Tax Audit shall be entitled to participate at its expense in
such defense and to employ counsel of its choice at its expense.

                                       75

     6.4.7  Buyer's Claiming, Receiving or Using of Refunds and Overpayments. If
after the Closing, Buyer, any Company, or any Subsidiary of a Company (A)
receives any refund or (B) utilizes the benefit of any overpayment of Taxes
which, in each case (A) and (B), (x) relates to Taxes paid by the Sellers or any
Company, or any Subsidiary of a Company with respect to a taxable period, or
portion thereof, ending on or before the Closing Date, or (y) is the subject of
indemnification by the Sellers pursuant to this Agreement, Buyer shall promptly
transfer, or cause to be transferred, to the Sellers the entire amount of the
refund or overpayment (including interest) resolved or utilized by Buyer, any
Company, or any Subsidiary of a Company. The Buyer agrees to notify the Sellers
within 15 days following the discovery of a right to claim any such refund or
overpayment and the receipt of any such refund or utilization of any such
overpayment. The Buyer agrees to claim any such refund or to utilize any such
overpayment as soon as possible and to furnish to the Sellers all information,
records and assistance necessary to verify the amount of the refund or
overpayment.

     6.4.8 Resolution of All Tax-Related Disputes. In the event that the Sellers
and Buyer cannot agree on the calculation of any amount relating to Taxes or the
interpretation or application of any provision of this Agreement relating to
Taxes, such dispute shall be resolved by a nationally recognized accounting firm
mutually acceptable to each of the Sellers and Buyer, whose decision shall be
final and binding upon all Persons involved and whose expenses shall be shared
equally by the Sellers, on the one hand, and Buyer on the other hand.

     6.4.9 Termination of Existing Tax Sharing Agreements. Any and all existing
Tax sharing agreements or arrangements, written or unwritten, binding any
Company or any Subsidiary of a Company, shall be terminated as of the Closing.

     6.4.10    Assistance and Cooperation. The parties agree that, after the
Closing Date:

               6.4.10.1  Buyer, on the one hand, and the Sellers, on the other
hand, shall each assist the other (and cause its respective Affiliates to
assist) the other party in preparing any Tax Returns which such other party is
responsible for preparing and filing;

               6.4.10.2  Buyer, on the one hand, and the Sellers, on the other
hand, shall cooperate fully in preparing for any Tax audits, or disputes with
taxing authorities, relating to any Tax Returns or Taxes of any Company or any
Subsidiary of a Company;

               6.4.10.3  Buyer, on the one hand, and the Sellers, on the other
hand, shall make available to each other upon written request and to any
taxing authority as reasonably requested in writing all relevant books and
records relating to Taxes but only to the minimum extent necessary to enable
the other party to prepare Tax Returns or resolve disputes with taxing
authorities relating to Tax Returns or Taxes of a  Company or a Subsidiary of a
Company. Any such information shall be kept strictly confidential;

               6.4.10.4  Buyer, on the one hand, and the Sellers, on the other
hand, shall promptly furnish the other party with copies of all relevant
correspondence received from any taxing authority in connection with any Tax
Audit or information request relating to Taxes for which such other party may
have an indemnification obligation under this Agreement; and

                                       77
<PAGE>   85
               6.4.10.5  Except as otherwise provided herein, the party
requesting assistance or cooperation shall bear the other party's out-of-pocket
expenses in complying with such request to the extent that those expenses are
attributable to fees and other costs of unaffiliated third-party service
providers.

          6.4.11    This Section 6.4 alone shall govern the procedure for all
Tax indemnification claims, notwithstanding any provision of Article 12.

          6.4.12    For purposes of this Agreement, "Due Date" shall mean, with
respect to any Tax Return, the date such return is due to be filed (taking into
account any valid extensions); and "Tax Item" shall mean, with respect to
Taxes, any item of income, gain, deduction, loss or credit or other tax
attribute.

     Section 6.5    Ordinary Course of Business.

execution of this Agreement of which that party obtains knowledge (including,
without limitation, knowledge that if in existence on the date of this

<PAGE>   94
Collective Bargaining Agreements, whether by transfer, lease, assignment,
corporate reorganization or otherwise, Buyer shall require, as an absolute
precondition of such sale, transfer, or conveyance, that the purchaser,
transferee, lessee or assignee of such assets assume the applicable Collective
Bargaining Agreement(s) and agree to be bound by the terms, conditions and
obligations thereof.

     Section 6.8 Pollution Control Bonds.  Notwithstanding any other provision
hereof, Buyer covenants and agrees that, after the Closing Date, Buyer will not
make any modifications to the "Purchased Assets" as defined under the Sithe/GPU
Agreements or take any action which, in and of itself, results in a loss of the
exclusion of interest on the "Pollution Control Revenue Bonds" as defined under
the Sithe/GPU Agreements issued on behalf of Jersey Central Power & Light
Company, Metropolitan Edison Company and Pennsylvania Electric Company (the
"GPU Sellers") in connection with such Purchased Assets from gross income for
federal income tax purposes under Section 103 of the Code. Actions with respect
to Purchased Assets shall not constitute a breach by Buyer of this Section 6.8
in the following circumstances: (i) Buyer ceases to use or decommissions any of
the Purchased Assets or subsequently repowers such Purchased Assets that are no
longer used or decommissioned (but does not hold such Purchased Assets for
sale); (ii) Buyer acts with respect to Purchased Assets in order to comply with
requirements under applicable federal, state or local environmental or other
laws or regulations; or (iii) Buyer acts in a manner the GPU Seller (i.e., a
reasonable private provider of electricity of similar stature as the GPU
Seller) would have acted during the term of the Pollution Control Revenue Bonds
(including, but not limited to, applying new technology). In the event Buyer
acts or anticipates acting in a manner that will cause a loss of the exclusion
of interest on the Pollution

                                       87
<PAGE>   95
Control Revenue Bonds from gross income for federal income tax purposes, Buyer
shall give prompt written notice to such effect. Buyer further covenants and
agrees that, in the event that Buyer transfers any of the "Purchased Assets" (as
described above), Buyer shall obtain from its transferee a covenant and
agreement that is analogous to Buyer's covenant and agreement pursuant to this
Section 6.8, including this sentence. In addition, Buyer shall not, without at
least 60 days' advance written notice to the GPU Seller, take any action which
would result in (x) a change in the use of the assets financed with the
Pollution Revenue Control Bonds from the use in which such assets were
originally intended, or (y) a sale of such assets separate from the generating
assets to which they relate; provided that no notice is required of the events
set forth in clause (i), (ii), or (iii) above. This covenant shall survive the
Closing and shall continue in effect so long as the Pollution Control Revenue
Bonds remain outstanding.

     Section 6.9    Certain Benefits Matters.

          6.9.1  Following the Closing, Buyer agrees to cause each Company and
each Subsidiary of each Company to honor and perform the obligations of such
Company and such Subsidiary under each Benefit Plan in accordance with the terms
of any such Benefit Plan and in accordance with the obligations imposed under
the Sithe/GPU Agreements and the Collective Bargaining Agreements; provided,
however, that Buyer, any Company and any Subsidiary of any Company may make any
lawful changes to any such Benefit Plan, or terminate any Benefit Plan, to the
extent permitted under the terms of such Benefit Plan, the Sithe/GPU Agreements,
the Collective Bargaining Agreements and applicable law. Effective as of the
Closing, Buyer shall assume in place of Sithe all the obligations of Sithe under
the Sithe/GPU Agreements that pertain to the Benefit Plans and shall cause
Sithe to be released from all such obligations. In the event

                                       88
<PAGE>   96
that any employees of a Company or Subsidiary of a Company are covered under a
Benefit Plan sponsored by Sithe that is required to be maintained on behalf of
such employees pursuant to the Sithe/GPU Agreements or a Collective Bargaining
Agreement, Buyer shall, or shall cause the Company or the Subsidiary of any
Company that employs such employees either to assume the sponsorship of such
Benefit Plan, accept a spin-off of the portion of such Benefit Plan covering
such employees, adopt a new Employee Benefit Plan or amend an existing Employee
Benefit Plan to provide the required benefits, as Buyer may determine, provided
that Buyer shall notify Sithe of the manner in which it will meet the obligation
described in this sentence at least thirty (30) days before the Closing and
cause Sithe to be released from its obligations under the Sithe/GPU Agreements
effective upon the Closing. Nothing in this Agreement shall preclude a
subsequent agreement by Buyer to assume the obligation to provide benefits under
any Employee Benefit Plan to any group of employees under one or more of the
Collective Bargaining Agreements with respect to service earned with a Company
or a Subsidiary of any Company for the period commencing November 24, 1999 and
ending on the Closing Date, subject to reimbursement of Buyer by Sithe for the
cost of any such benefits, calculated as Buyer and Sithe may agree, and subject
to the agreement of the Union that represents the affected employees.

     6.9.2     Following the Closing, Buyer shall cause each Company and each
Subsidiary of each Company to (A) waive all pre-existing conditions,
exclusions, and waiting periods with respect to participation and coverage
requirements applicable to the employees of such Company and each such
Subsidiary and their covered dependents under any group health plan, within the
meaning of Section 5000(b)(1) of the Code, in which such employees may be


                                       89
<PAGE>   97
eligible to participate after the Closing Date except to the extent that such
pre-existing conditions, exclusions and waiting periods were in effect in the
Benefit Plans that covered such employees prior to the Closing; (B) provide
each employee of such Company and each such Subsidiary with credit for payments
made by such employee or his covered dependents prior to the Closing Date for
purposes of satisfying any applicable deductible or out-of-pocket requirements
under any such group health plan, and (C) give credit, to employees of such
Company and each such Subsidiary, for purposes of satisfying any eligibility or
vesting requirements of (but not for purposes of benefit accrual under) any
Employee Benefit Plan, or other benefit program or arrangement in which
employees of such Company and each such Subsidiary may be eligible to
participate after the Closing Date, for services rendered by such employees
prior to the Closing Date to such Company and each such Subsidiary or, to the
extent recognized by the Benefit Plans, for services rendered to any other
Person; provided, that the foregoing shall not apply to the extent it would
result in duplication of benefits.

     Section 6.10 WARN Act. Sellers and the Companies will provide Buyer on or
prior to the Closing Date with a written list of all employees of the Companies
or their Subsidiaries whose employment has been terminated and whose work hours
have been reduced within 90 calendar days preceding the Closing Date. Such list
will indicate the employee's site of employment, position or job title, name,
starting and ending dates of employment and date of employment loss,
termination, layoff and, if applicable, the amount of hour reduction. If a
plant closing or a mass layoff occurs or is deemed to occur with respect to any
Company or any Subsidiary of any Company or any of their respective facilities
in connection with the transactions contemplated in this Agreement or at any
time after the Closing, Buyer shall be

                                       90
<PAGE>   98
solely responsible for providing all notices required under the Work Adjustment
and Retraining Notification Act, 29 U.S.C. Section 2109 et seq. or the
regulations promulgated thereunder (the "WARN Act") and for taking all remedial
measures, including, without limitation, the payment of all amounts, penalties,
liabilities, costs and expenses if such notices are not provided.

     Section 6.11 Sithe Release from GPU Liabilities. If requested by Sithe,
Buyer shall use reasonable efforts to cause all third parties to release Sithe
and its Affiliates and their successors and assigns (other than the Companies
and their Subsidiaries) from all GPU Liabilities and to obtain the
acknowledgment or consent of any third party of or to the assumption by Buyer of
the GPU liabilities as provided in Article 12; provided that the failure to
cause such release or obtain such acknowledgment or consent shall not affect
Buyer's obligations under Article 12.

     Section 6.12 Change of Entity Names. Buyer acknowledges and agrees that the
trade name "Sithe" shall not be deemed an Acquired Asset and that the Sellers
shall be permitted (but shall not be required), on or prior to the Closing, to
cause each Company and each Subsidiary of each Company to change its name such
that the name "Sithe" is not used in any such entity's name. Following the
Closing Date, Buyer shall, upon the request of any Seller, cause any Company or
any Subsidiary of any Company the name of which includes the name "Sithe" to
change its name within 90 days of such request to exclude the name "Sithe."

     Section 6.13 Interim Services Agreement. As promptly as practicable but in
any event within 30 days of the date of this Agreement, Buyer and Sithe shall
negotiate in good faith and use reasonable efforts to enter into an Interim
Services Agreement with respect to the services and on the terms and conditions
described in Schedule 1C; provided that the execution and

                                       91
<PAGE>   99
delivery of the Interim Services Agreement shall not be a condition to the
performance by any party of any of such party's obligations under this
Agreement.

     Section 6.14 Environmental Matters/ISRA. Buyer acknowledges that Sithe New
Jersey Holdings, LLC has entered into agreements with the New Jersey Department
of Environmental Protection ("NJDEP") pursuant to the New Jersey Industrial Site
Recovery Act ("ISRA"), N.J.S.A. Sections 13:1K-6 et seq., ("Remediation
Agreements") which obligate Sithe New Jersey Holdings, LLC to conduct a
Remediation of the Glen Gardner, Sayreville, Werner and Gilbert generating
facilities in conformance with applicable State standards. The Sellers shall
cause Sithe New Jersey Holdings, LLC to take such actions as are necessary to
obtain such authorizations as are required to consummate the transactions
contemplated by this Agreement in compliance with ISRA, including the filings of
any General Information Notices and any other required ISRA documents and
applications. Buyer agrees to cooperate with the Sellers and Sithe New Jersey
Holdings, LLC in these efforts, which cooperation shall include, but shall not
be limited to, execution of, or consenting to, ISRA related applications,
submissions or remediation agreements with NJDEP and the establishment of
remediation funding sources satisfactory to NJDEP. Buyer agrees that the Sellers
and their Affiliates shall have no responsibility for compliance with ISRA after
Closing. Pursuant to Section 12.1 of this Agreement, at Closing, Buyer shall
assume all of the Sellers' ISRA obligations and liabilities related to the GPU
Assets and shall indemnify and hold harmless the Sellers, their Affiliates
(other than the Companies and their Subsidiaries) and their shareholders for any
costs or liabilities associated with the remediation of the GPU Assets,
including those obligations and liabilities addressed in the existing
Remediation Agreements between Sithe New Jersey Holdings, LLC and NJDEP and any

                                       92
<PAGE>   100
further ISRA obligations or liabilities arising as a result of this Agreement,
provided, that Buyer's obligation to indemnify and hold harmless the Sellers,
their Affiliates (other than the Companies and their Subsidiaries) and their
shareholders shall not apply to any fines or penalties imposed by NJDEP arising
out of Sellers' decision to close the transactions provided for in this
Agreement without obtaining NJDEP's authorizations pursuant to ISRA.

that in the absence of any such written instructions from Buyer at or prior to

          10.1.3 by Sithe at any time after September 30, 2000 if any of the
conditions provided for in Article 8 of this Agreement shall not have been
satisfied or waived in writing by Sithe in its sole discretion prior to such
date; provided, that if any condition in Article 8 has not been so satisfied or
waived and diligent efforts are being undertaken to satisfy such condition,
including, but not limited to, efforts to cure any breach of any representation
or warranty, then the references to September 30, 2000 in this Section 10.1.3

notice, there has been a violation or breach by any Seller of any agreement,
representation or warranty contained in this Agreement which, individually or
in the aggregate, has or would have a Material Adverse Effect and which is not
susceptible to cure (or if so susceptible is not the subject of diligent
efforts on the part of the breaching party to cure; provided that no such
efforts shall affect the time periods set forth in Section 10.1.2); provided,
that Buyer is not in material violation or breach of its agreements,
representations or warranties contained in this Agreement, or (b) by Sithe
upon not less than 30 days, prior written notice, if there has been a material
violation or breach by Buyer of any agreement, representation or warranty

<PAGE>   111
provided, that the Sellers are not in material violation or breach of their
agreements, representations or warranties contained in this Agreement.

     Section 10.2 Procedure Upon Termination and Consequences. Buyer or Sithe,
as the case may be, may terminate this Agreement when permitted pursuant to
Section 10.1 by delivering written notice of such termination, and such

          10.2.1 Buyer will deliver all documents, work papers and other
materials relating to the transactions contemplated hereby, whether obtained

          10.2.2 no party hereto shall have any liability or further obligation

Agreement, including with respect to information that is subject to the

covenant or agreement.

ARTICLE 12.  ASSUMPTION OF GPU LIABILITIES; INDEMNIFICATION

     Section 12.1  Assumption of GPU Liabilities; Indemnification.  At the
Closing, Buyer shall assume, pursuant to an instrument substantially in the
form attached hereto as Schedule 12.1, all obligations and liabilities of any
kind, whether fixed, contingent, accrued or otherwise, that any Seller or any
Affiliate of any Seller (other than any Company or any Subsidiary of any
Company) or any of their respective successors or assigns may have under, with
respect to or in connection with the GPU Liabilities. Buyer shall indemnify,
defend and hold harmless each Seller, their Affiliates (other than the
Companies and their Subsidiaries) and their respective

                                      105
<PAGE>   113
officers, directors, employees, shareholders, Affiliates and agents (each, an
"Indemnitee") from and against any and all claims, demands, suits, losses,
liabilities, damages, obligations, payments, costs and expenses (including,
without limitation, the costs and expenses of any and all actions, suits,
proceedings, assessments, judgments, settlements and compromises relating
thereto and reasonable attorneys' fees and reasonable disbursements in
connection therewith) (each, an "Indemnifiable Loss"), asserted against or
suffered by any Indemnitee relating to, resulting from or arising out of (i) the
GPU Liabilities or (ii) any Third Party Claims against any Indemnitee arising
out of or in connection with the Acquired Assets, including the acquisition,
ownership or operation thereof.

     Section 12.2  Defense of Claims.

          12.2.1  If any Indemnitee receives notice of the assertion of any
claim or of the commencement of any claims, action, or proceeding made or
brought by any Person (including Guarantor, Buyer, their respective Affiliates,
officers, directors and shareholders, and the successors and assigns of any
such Person) (a "Third Party Claim") with respect to which indemnification is
to be sought from a Person that is required to indemnify such Indemnitee (an
"Indemnifying Party"), the Indemnitee shall give such Indemnifying Party
reasonably prompt written notice thereof but in any event such notice shall not
be given later than ten (10) calendar days after the Indemnitee's receipt of
notice of such Third Party Claim. Such notice shall describe the nature of the
Third Party Claim in reasonable detail and shall indicate the estimated amount,
if practicable, of the Indemnifiable Loss that has been or may be sustained by
the Indemnitee. In addition, the Indemnitee shall transmit to the Indemnifying
Party a copy of all papers served with respect to such claim (if any). The
Indemnitee shall cooperate in good faith

                                      106
<PAGE>   114
in such defense at the Indemnifying Party's expense. If the Indemnifying
Party shall acknowledge in writing to the Indemnitee that the Indemnifying Party
shall be obligated to indemnify the Indemnitee under the terms of its indemnity
hereunder in connection with such Third Party Claim, then the Indemnifying Party
will have the right to participate in or, by giving written notice to the
Indemnitee, to elect to assume the defense of any Third Party Claim at such
Indemnifying Party's expense and by employing such Indemnifying Party's own
counsel; provided that the counsel for the Indemnifying Party who shall conduct
the defense of such Third Party Claim shall be reasonably satisfactory to the
Indemnitee. If an Indemnifying Party elects not to assume the defense of any
Third Party Claim, the Indemnitee may compromise or settle such Third Party
Claim over the objection of the Indemnifying Party, which settlement or
compromise shall conclusively establish the Indemnifying Party's liability
pursuant to this Agreement.

     12.2.2 (i) if, within ten (10) calendar days after an Indemnitee provides
written notice to the Indemnifying Party of any Third Party Claims, the
Indemnitee receives written notice from the Indemnifying Party that such
Indemnifying Party has elected to assume the defense of such Third Party Claim
as provided in Section 12.2.1, the Indemnifying Party will not be liable for any
legal expenses subsequently incurred by the indemnitee in connection with the
defense thereof; provided, however, that if the Indemnifying Party shall fail to
take reasonable steps necessary to defend diligently such Third Party Claim
within twenty (20) calendar days after receiving notice from the Indemnitee, the
Indemnitee may assume its own defense and the Indemnifying Party shall be liable
for all reasonable expenses thereof. (ii) Without the prior written consent of
the Indemnitee, the Indemnifying Party shall not enter into any settlement of

                                      107
<PAGE>   115
any Third Party Claim which would lead to liability or create any financial or
other obligation or restriction on the part of the Indemnitee for which the
Indemnitee is not entitled to indemnification hereunder. If a firm offer is made
to settle a Third Party Claim without leading to liability or the creation of a
financial or other obligation on the part of the Indemnitee for which the
Indemnitee is not entitled to indemnification hereunder the Indemnifying Party
desires to accept and agree to such offer, the Indemnifying Party shall give
written notice to the Indemnitee to that effect. If the Indemnitee fails to
consent to such firm offer within ten (10) calendar days after its receipt of
such notice, the Indemnifying Party shall be relieved of its obligations to
defend such Third Party Claim and the Indemnitee may contest or defend such
Third Party Claim. In such event, the maximum liability of the Indemnifying
Party as to such Third Party Claim will be the amount of such settlement offer
plus reasonable costs and expenses paid or incurred by Indemnitee up to the date
of said notice.

     12.2.3 Any claim by an Indemnitee on account of an Indemnifiable Loss which
does not result from a Third Party Claim (a "Direct Claim") shall be asserted by
giving the Indemnifying Party reasonably prompt written notice thereof, stating
the nature of such claim in reasonable detail and indicating the estimated
amount, if practicable, and the Indemnifying Party shall have a period of thirty
(30) calendar days after the Indemnifying Party's receipt of such notice within
which to respond to such Direct Claim. If the Indemnifying Party does not
respond within such thirty (30) calendar days period, the Indemnifying Party
shall be deemed to have accepted such claim. If the Indemnifying Party rejects
such claim, the Indemnitee will be free to seek enforcement of its rights to
indemnification under this Agreement.

     12.2.4 Notwithstanding anything to the contrary contained herein:


                                      108

<PAGE>   116

               12.2.4.1  Any Indemnitee shall use reasonable efforts to
mitigate all losses, damages and the like relating to a claim under these
indemnification provisions, including availing itself of any defenses,
limitations, rights of contribution, claims against third Persons and other
rights at law or equity. The Indemnitee's reasonable efforts shall include the
reasonable expenditure of money to mitigate or otherwise reduce or eliminate
any loss or expenses for which indemnification would otherwise be due, provided
that the Indemnitee shall only be required to make expenditures if and to the
extent that the Indemnifying Party shall have advanced funds to the Indemnitee
for such expenditures after notice from the Indemnitee to the Indemnifying
Party that such an expenditure would be required.

               12.2.4.2  Any Indemnifiable Loss shall be net of the dollar
amount of any insurance or other proceeds actually received by the Indemnitee
with respect to the Indemnifiable Loss, but shall not take into account any
income tax benefits to the Indemnitee, or any income taxes attributable to the
receipt of any indemnification payments hereunder. Any party seeking indemnity
hereunder shall use reasonable efforts to seek coverage (including both costs
of defense and indemnity) under applicable insurance policies with respect to
any such Indemnifiable Loss; provided, that the failure to seek or obtain such
coverage shall affect such party's rights pursuant to this Article 12, and
provided, further, that no such party seeking indemnification shall be
required to enter into or maintain any insurance policy or incur additional
insurance premiums pursuant to this Section 12.2.4.2.

                                      109
<PAGE>   117
     The expiration or termination of any covenant or agreement shall not affect
the parties' obligations under this Section of the Indemnitee provides the
Indemnifying Party with proper notice of the claim or event for which
indemnification is sought prior to such expiration, termination or
extinguishment.

     Notwithstanding anything to the contrary herein, no party (including an
Indemnitee) shall be entitled to recover from any other party (including an
Indemnifying Party) for any liabilities, damages, obligations, payments,
losses,  costs, or expenses under this Agreement any amount in excess of the
actual compensatory damages, court costs and reasonable attorney's fees and
other advisor fees suffered by such party. Buyer and the Sellers waive any
right to recover punitive, incidental, special, exemplary and consequential
damages arising in connection with or with respect to this Agreement. The
provisions of this last paragraph of Section 12.2.4.2 shall not preclude
recovery of an Indemnifiable Loss by an Indemnitee to the extent such
Indemnifiable Loss is payable to a third party in connection with a Third
Party Claim.

     12.2.5 A failure to give timely notice as provided in this Section 12.2
shall not affect the rights or obligations of any party hereunder expect if,
and only to the extent that, as a result of such failure, the party which was
entitled to receive such notice was actually prejudiced as a result of such
failures.

     12.2.6 If the amount of any Indemnifiable Loss, at any time subsequent to
the making of an indemnity payment in respect thereof, is reduced by recovery,
settlement or otherwise under or pursuant to any insurance coverage, or
pursuant to any claim, recovery, settlement or payment by, from or against any
other entity, the amount of such reduction, less

                                      110
<PAGE>   118
any costs or expenses incurred in connection therewith shall promptly be repaid
by the Indemnitee to the Indemnifying Party.

ARTICLE 13.  OBLIGATIONS OF GUARANTOR

     Section 13.1  Guarantee.  In order to induce the Sellers to enter into
this Agreement and to consummate the transactions contemplated hereby, and for
other good and valuable consideration received, Guarantor irrevocably and
unconditionally guarantees Buyer's obligation to pay promptly when due the
Aggregate Purchase Price in accordance with the terms of this Agreement (the
"Guaranteed Obligations"). No invalidity, irregularity or unenforceability of
all or any part of the Guaranteed Obligations, or of any security therefor,
shall affect, impair or be a defense to the foregoing guarantee nor shall any
other circumstances which may otherwise constitute a defense available to, or
legal or equitable discharge of, Guarantor in respect of the Guaranteed
Obligations, or of any security therefor, or in respect of the foregoing
guarantee affect, impair or be a defense to the foregoing guarantee. The
liability of Guarantor hereunder is absolute, primary and unconditional and
shall not be subject to any offset, defense or counterclaim of Guarantor.
Guarantor also agrees that no Seller need attempt to collect any part of the
Guaranteed Obligations from Guarantor or others, but may require Guarantor to
make immediate payment of the Guaranteed Obligations when due or at any time
thereafter. To the fullest extent permitted by law, Guarantor hereby waives all
defenses, counterclaims and all suretyship defenses.

                                      111
<PAGE>   119
     Section 13.2  Representations and Warranties Regarding Guarantor.
Guarantor represents and warrants to the Sellers that, as of the date hereof
(except where such representation or warranty is expressly made only as of a
specific date) as follows:

          13.2.1  Organization and Corporate Power.  Guarantor is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Texas. Guarantor has full corporate power and authority to execute,
deliver and perform this Agreement.

          13.2.2  Authorization; Validity.  The execution, delivery and
performance by Guarantor of this Agreement have been duly authorized by all
requisite corporate action on the part of Guarantor. This Agreement has been
duly executed and delivered by Guarantor and constitutes the valid and binding
obligation of Guarantor, enforceable against Guarantor in accordance with its
terms, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally, and general equitable principles
(whether considered in a proceeding in equity or at law).

          13.2.3  No Conflict.  The execution, delivery and performance by
Guarantor of this Agreement and the consummation of the transactions
contemplated hereby will not (i) violate the articles of incorporation or
by-laws of Guarantor; (ii) violate any law or regulation applicable to
Guarantor, or any order of any Governmental Authority having jurisdiction over
Guarantor, or (iii) violate or conflict with, or constitute (with due notice or
lapse of time or both) a default under, any Contract by which Guarantor or any
of its assets is bound.

          13.2.4  Consents and Approvals.  No registration or filing with, or
consent or approval of or other action by, any Governmental Authority or any
other Person is or will be

                                      112
<PAGE>   120
necessary for the valid execution, delivery and performance by Guarantor of its
obligations under this Agreement.

     Section 13.3   Covenants Relating to Buyer.

          13.3.1  Guarantor hereby covenants and agrees that, for a period
commencing on the Closing Date and terminating on the second anniversary of the
Closing Date, Guarantor shall cause Buyer at all times to maintain (i) a Net
Worth equal to the greater of (a) $611 million or (b) an amount that is not
significantly less than the Net Worth of Buyer immediately after the Closing,
and (ii) sufficient net assets to discharge and perform its obligations
pursuant to this Agreement. Not later than forty five (45) days after the
Closing Date, Guarantor shall deliver to the Sellers a certificate of the Chief
Financial Officer of Guarantor (or an officer of Guarantor serving in a similar
capacity)(the "Chief Financial Officer of Guarantor") setting forth the Net
Worth of Buyer and its Subsidiaries as of the end of the calendar month
immediately preceding the month in which the Closing occurs, on a pro forma
basis to give effect to the purchase of the Intercompany Notes, the LLC
Interests and the Sithe Mid Atlantic Stock (the "CFO Certificate") and
certifying that the amount set forth in the CFO Certificate has been derived
from a historical balance sheet prepared in accordance with GAAP and that the
adjustments thereto are based upon reasonable assumptions. Not later than (y)
the 45th day after the last day of each of the first, second and third fiscal
quarters of Buyer and (z) the 100th day after the last day of each fiscal year
of Buyer, Guarantor shall provide Sithe with a certificate of the Chief
Financial Officer of Guarantor to the preceding fiscal quarter (or fiscal year,
in the case of any such certificate delivered with respect to a fiscal year-end
balance sheet).

                                      113
<PAGE>   121
          13.3.2  Upon the reasonable request of Sithe in connection with a
possible acquisition, merger, consolidation, financing or other similar
transaction, Buyer shall provide to Sithe, upon not less than 10 Business Days'
prior notice, the most recent year-end audited consolidated balance sheet of
Buyer and its Subsidiaries (and, if such request is made later than the 135th
day following the last day of Buyer's fiscal year, the most recent
unaudited consolidated balance sheet of Buyer and its Subsidiaries) together
with a certificate of the Chief Financial Officer of Buyer that such balance
sheet or balance sheets have been prepared in accordance with GAAP; provided
that in no event shall Buyer be required to deliver the foregoing balance
sheets pursuant to this Section 13.3.2: (a) more frequently than twice in any
365-day period; and (b) unless Buyer and Sithe (and any third party to which
Sithe proposes to provide copies of such balance sheets) shall have executed a
confidentiality agreement reasonably satisfactory to Buyer and Sithe. In
addition, if there is a claim or threatened claim against Sithe or any of its
Affiliates with respect to any matter as to which Buyer is obligated to provide
indemnification pursuant to Article 12 and, based on the advice of Sithe's
independent auditors, in the absence of evidence of Buyers ability to satisfy
such obligation, such claim or threatened claim will be required to be
disclosed, in footnotes or otherwise, in Sithe's consolidated financial
statements, then upon the reasonable request of Sithe, Buyer shall provide to
Sithe, upon not less than 10 Business Days' prior notice, the financial
statements referred to the preceding sentence, but without regard to the number
of other requests that Sithe may have delivered during the preceding 365-day
period.

          13.3.3  Notwithstanding Section 13.3.1, Guarantor may elect, at any
time on or prior to the second anniversary of the Closing Date, to terminate
Section 13.3.1 by delivering to the Sellers a guarantee of all of Buyer's
obligations hereunder in form and substance satisfactory

                                      114
<PAGE>   122
to the Sellers in their sole discretion by either (a) Guarantor or (b) another
Person, provided that such other Person has (i) a Net Worth greater than or
equal to the Net Worth of Guarantor immediately prior to the date of such
assumption and (ii) either (A) securities listed on a national securities
exchange in the United States, Britain, Japan, France, Germany, the Netherlands
or Belgium, (B) an investment grade credit rating for long term unsecured
indebtedness from either Standard and Poors Rating Group, a division of the
McGraw-Hill Industries, Inc., or Moody's Investors Services, Inc. or (C) a
financial condition reasonably acceptable to Sithe, as determined based upon
financial statements that are mutually acceptable to Guarantor and Sithe. Any
such guarantee shall terminate on the second anniversary of the Closing Date.

ARTICLE 14.  MISCELLANEOUS

     Section 14.1 Amendment and Modification. This Agreement may be amended,
modified and supplemented only by written agreement of Buyer and Sithe.

     Section 14.2 Waiver of Compliance. Any failure of Buyer, on the one hand,
or any Seller, on the other hand, to comply with any obligation, covenant,
agreement or condition contained herein may be expressly waived in writing by
Sithe, in the event of any such failure by Buyer, or by Buyer, in the event of
any such failure by any Seller, but such waiver or failure to insist upon strict
compliance shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.

communications required or permitted to be given under this Agreement shall be

     Section 14.4   Binding Nature; Assignment. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective

parties hereto without prior written consent of (i) in the case of an assignment

Buyer; provided, that Buyer may assign and delegate its rights, interests and
obligations hereunder to one or more wholly-owned direct or indirect

<PAGE>   125
Sithe (which shall contain a representation that the assignee is a wholly-owned
Subsidiary of Buyer or Guarantor) at or before the Closing Date, in which event
Buyer shall remain liable for all of its obligations under this Agreement and
such Subsidiary or Subsidiaries shall, together with Buyer, be jointly and
severally liable for such obligations. Nothing contained herein, express or
implied, is intended to confer on any Person other than the parties hereto or
their successors and assigns, any rights, remedies, obligations or liabilities
under or by reason of this Agreement. Notwithstanding the proviso contained in
the immediately preceding sentence, Buyer may not assign its rights, interests
and obligations hereunder if such assignment could reasonably be expected to
result in a delay or impediment to consummating those transactions hereunder

     The references to the following matters are for the information of Buyer.
The inclusion of each such matter does not constitute a representation with
respect to its materiality, is not intended to establish a standard of
materiality or significance and shall not be deemed to have such effect.

     See title exception for condemnation proceeding for the Warren Station on
Schedule 3.14.

     In order to comply with Article 5 of the license for the Piney Project
(FERC No. 309), GPU is currently pursuing two condemnation actions against the
owners of certain lands around the reservoir in order to eliminate certain title
issues. Article 5 requires that the licensee obtain and retain throughout the
term of the license the right to use projects lands in perpetuity. Section 21 of
the Federal Power Act authorizes licensees to bring eminent domain actions to
secure lands necessary for a project.

                          COMPLIANCE WITH LAW; PERMITS


     The references to the following matters are for the information of Buyer.
The inclusion of each such matter does not constitute a representation with
respect to its materiality, is not intended to establish a standard of
materiality or significance and shall not be deemed to have such effect.

          1. See Schedule 3.17 for environmental matters.

          2. In order to comply with Article 5 of the license for the Piney
Project (FERC No. 309), GPU is currently pursuing two condemnation actions
against the owners of certain lands around the reservoir in order to eliminate
certain title issues. Article 5 requires that the licensee obtain and retain
throughout the term of the license the right to use projects lands in
perpetuity. Section 21 of the Federal Power Act authorizes licensees to bring
eminent domain actions to secure lands necessary for a project.

          3. Application for renewal of Anchorage Lease at Sayreville sent to
Sithe New Jersey Holdings LLC directly from New Jersey Tidelands Council.

          4. There are bankruptcy proceedings of Material Recovery Group, to
which Sithe and its affiliates are not parties, relating to the Erie West
Primary Access (see #69 of Schedule 1B).

          5. In connection with its ownership of the GPU Assets and the conduct
of its business as currently conducted, Seller, by or through its subsidiaries,
has applied for or filed for amendments, renewals, or reissuance of certain
Environmental Permits. Applications for such amended, renewed, or reissued
permits or activities initiated by Governmental Authorities that are still
pending before the relevant Governmental Authorities include:

               i.   Reissuance of the Residual Solid Waste Disposal Permits by
                    PADEP for the Keystone, Conemaugh and Shawville stations,
                    which will reflect the change in the name of the permittee
                    from GPU Genco to Northeast Management, as appropriate;

               ii.  Minor modification of the Residual Solid Waste Disposal
                    Permits by PADEP for the Portland and Titus stations, which
                    will reflect the change in the name of the permittee from
                    GPU Genco to Northeast Management;

               iii. Approval of replacement financial security by PADEP as
                    required by the Residual Solid Waste Disposal Regulations
                    for the Conemaugh, Shawville and Seward stations;



                                      S-25


<PAGE>   162
iv.     Renewal of expired wastewater disposal ("NPDES") permits by PADEP for
        the Conemaugh, Seward and Williamsburg stations;

v.      Modification of the NPDES permits by PADEP for Keystone and Conemaugh
        stations to reflect the change in name of the permittee from GPU Genco
        to Northeast Management;

vi.     Modification of the Water Quality Management Permits issued by PADEP
        for the Keystone and Conemaugh stations to reflect the change in name
        of the permittee from GPU Genco to Northeast Management;

vii.    Renewal by NJDEP of the Riparian License for the Sayreville station;

viii.   Modification of the Submerged Lands License issued by the Commonwealth
        of Pennsylvania for the Shawville station to reflect the change in
        ownership from Penelec to Sithe Pennsylvania Holdings LLC. Additional
        Submerged Lands Licenses may need to be obtained from the Commonwealth
        of Pennsylvania in connection with certain Dams and Enroachment Permits
        issued by PADEP to the extent that such Licenses are required by
        Pennsylvania law and have not yet been obtained. Based upon verbal
        communications with PADEP and the Governor's office, Sellers'
        understanding is that, although Submerged Lands Licenses are required
        by State law, such Licenses have not been uniformly required or issued
        and that enforcement of the requirement for a particular license will
        be addressed in the context of applications to PADEP for renewal or
        modification of Dams and Enroachment Permits;

ix.     Renewal of expired air pollution control operating permits or
        certificates for several facilities in both Pennsylvania and New
        Jersey. Both PADEP and NJDEP are not reissuing the expired permits or
        certificates to operate and have authorized continued operation of the
        stations in compliance with the terms and conditions of the expired
        permits or certificates to operate until such time as they take final
        action on the stations' applications for Title V operating permits or
        "synthetic minor" operating permits. Title V operating permit
        applications have been filed and are still pending for the Gilbert,
        Glen Gardner, Sayreville, Warren, Titus, Conemaugh, Seward, Shawville
        and Keystone stations. Synthetic minor operating permit applications
        are still pending for Blossburg, Hamilton, Hunterstown, Mountain,

          32.  Severance and Retention Agreements for Alan Metzler (Tier #3) and

2. Exceptions To Qualification.

     3.12.3  An application has been filed with the Internal Revenue Service for
a determination on the qualification of the Sithe New England Power Services,
Inc. Union Pension Plan, but no letter has yet been issued.

     From the closing date of the transactions contemplated by the Sithe/GPU
Agreements ("GPU Closing") until the payment of wages of employees of the
Companies and their Subsidiaries for the payroll dated February 8, 2000,
certain deductions for contributions to the Sithe Energies Group Retirement
401(k) Plan ("401(k) Plan") were untimely made, and in the case of certain
employee after-tax contributions, were also untimely paid to the trust under the
401(k) Plan. These operational failures, attributable to the changeover of
payroll systems resulting from such transactions, have been corrected. It is
anticipated that Sithe will contribute an amount to the trust under the 401(k)
Plan on behalf of affected participants equal to lost investment earnings for
contributions that were deducted and contributed in a manner that was
inconsistent with the plan's customary timing for other plan participants for
the relevant time period.

     3.12.7  A prohibited transaction occurred as a result of failure to timely
contribute employee after-tax contributions to the trust established under the
401(k) Plan for the period from the GPU Closing through February 8, 2000. As
soon as the excise tax can be calculated, Federal Form 5330 will be prepared
and filed with the Internal Revenue Service and the excise tax will be paid.
See discussion at 3.12.3.

     3.12.8  The Severance and Retention Agreements for Alan Metzler and Robert
Sipes provide for additional benefits as a result of the transactions
contemplated by this Agreement.

     3.12.10.  Contributions of certain employees' after-tax contributions to
the trust established under the 401(k) Plan were untimely made. See discussion
at 3.12.3.

     3.12.12.  The Sithe Pension Plan ("Pension Plan"), a cash balance pension
plan, has been approved by the officers of Sithe effective January 1, 2000 and
has been formally announced to the non-represented employees of Sithe and its
subsidiaries, including the employees of the Companies and their Subsidiaries.
The Pension Plan is in the process of being drafted and has not yet been adopted
by the Board of Directors of Sithe. None of the groups of employees covered
under the Collective Bargaining Agreements are covered under the Pension Plan at
present.

                             ENVIRONMENTAL MATTERS




     The references to the following matters are for the information of Buyer.
The inclusion of each such matter does not constitute a representation with
respect to its materiality, is not intended to establish a standard of
materiality or significance and shall not be deemed to have such effect.

          1.  The Seward Station is subject to a Consent Order and Agreement
that includes the remediation of a coal ash site. Cost estimates for remediation
of the site have ranged from approximately $5 million to $20 million.

          2.  Sithe New Jersey Holdings LLC is responsible for remediation at
several former GPU facilities in New Jersey under ISRA. Sithe New Jersey
Holdings LLC estimates the cost to remediate such sites to be approximately $5
million based on the level of financial security requested by the New Jersey
Department of Environmental Protection.

          3.   The U.S. Environmental Protection Agency ("EPA") recently filed
suits or announced its intention to file suits against a number of coal-fired
power facilities in Midwestern and Eastern States regarding alleged violations
of the prevention of significant deterioration and nonattainment provisions of
the New Source Review ("NSR") requirements under the Clean Air Act. In 1998, EPA
requested information relating to the Conemaugh Station as part of a broader
industry information request that has formed the basis for EPA's NSR actions
against coal-fired power plants.

          4.   Matters reflected in Schedule 3.6.

          6.  Emission Allowances and Emission Reduction Credits

  Attached are the following items:

     A.  Sulfur Dioxide (SO2) allowances currently held in Sellers' or Company
Accounts for the GPU Assets as recorded in EPA's Allowance Tracking System as
of February 9, 2000;

     B.  Nitrogen Oxide (NOx) Allowances currently held in Sellers' or
Company's Accounts for the GPU Assets as recorded in EPA's NOx Allowance
Tracking System as of February 9, 2000. The rights to certain additional
allocations of NOx allowances is governed by the New Jersey NOx Emission
Allowances letter agreement between Sithe New Jersey Holdings LLC and GPU, Inc.
dated November 24, 1999;

     C.  Estimated future allocations of NOx Allowances for the GPU Assets
based upon prior allocations and anticipated regulatory developments;

     D.  Emission Reduction Credits relating to the GPU Assets that have been
approved by each relevant Governmental Authority the rights to which are
presently held by either the Companies or their Subsidiaries, either directly
or through the ERC Administration Letter Agreement between Penelec and Sithe
Pennsylvania Holdings LLC, dated November 24, 1999.

     With regard to the above items:

     The SO2 and NOx allowances identified as being currently held in Sellers'
or Company's accounts do not reflect deductions that will occur in early 2000
for reconciliation with 1999 actual emissions;

     Allowances identified for the Keystone and Conemaugh facilities reflect
the total allowances allocated for those facilities rather than Sellers' or its
subsidiaries' share in or rights to those allowances;

     Future allocations of NOx allowances are subject to pending regulatory and
legal reviews and proceedings and, accordingly, are subject to modification. No
representation or warranty is made with respect to Buyer's actual receipt of
any such future allocation;

     No representation is made with respect to whether any particular Emission
Reduction Credit identified herein will qualify for or be deemed otherwise
sufficient for use by the Buyer (or subsequent owner of the rights thereto) for
compliance with any applicable Environmental Law.

                              CERTAIN GPU MATTERS

     1.   GPU Post Closing Amounts.

     2.   The following agreements have not been executed by all parties
thereto:

     Assignment and Assumption Agreement between the Conemaugh Station Owners
and Sithe Power Marketing, L.P., dated as of November 24, 1999.

     Assignment and Assumption Agreement between the Keystone Station Owners
and Sithe Power Marketing, L.P., dated as of November 24, 1999.

     Energy Services Agreement between the Conemaugh Station Owners and Sithe
Power Marketing, L.P., dated as of November 24, 1999.

     Energy Services Agreement between the Keystone Station Owners and Sithe
Power Marketing, L.P., dated as of November 24, 1999.

     3.   Following Vivendi's September 1999 announcement of its intention to
sell Sithe, the Keystone/Conemaugh Owner's Committee (the "Owners Committee")
decided to hold a vote to decide whether to provide notice of termination of the
operating agreements between Northeast Management and the owners of each of
Keystone and Conemaugh. Pursuant to Section 1.1 of each operating agreement, for
a termination to be effective in January 2002, the owners were required to
provide notice on or prior to December 31, 1999. Some owners suggest voting to
terminate the operating agreements because the buyer of Sithe was unknown and in
any event the actual termination would not be effective until January 2002.
Furthermore, upon learning the identity of the buyer of Sithe, the Owners'
Committee could vote to cancel termination. However, if the Owners' Committee
delayed voting beyond December 31, 1999, the termination would not be effective
until January 2003. Sithe suggested that it would be willing to treat any
termination vote taken before June 30, 2000 to be effective as if it occurred
before December 31, 1999. The Owner's Committee voted not to give notice of
termination of the operating agreements and instead accepted Sithe's proposal.
The details of this matter were reflected in the minutes of the December 1999
meeting of the Owners Committee which have been previously provided to Buyer.

                  GENERAL TRANSFER AND CONVEYANCING INSTRUMENT

               ASSIGNMENT AND TRANSFER AGREEMENT AND BILL OF SALE

     ASSIGNMENT AND TRANSFER AGREEMENT AND BILL OF SALE, dated as of
__________, 2000 (this "Agreement"), by and among [entity or entities
designated by Reliant Energy Power Generation, Inc.] ("Assignee"), Sithe
Energies, Inc., a Delaware corporation ("Sithe"), Sithe Northeast Generating
Company, Inc., a Delaware corporation and an indirect wholly-owned Subsidiary
of Sithe ("Genco"), and Sithe Power Marketing L.P., a Delaware limited
partnership and an indirect wholly-owned Subsidiary of Sithe ("SPMLP" and,
together with Sithe and Genco, the "Sithe Entities") [OTHER SITHE SUBSIDIARIES
HOLDING ACQUIRED ASSETS].

                              W I T N E S S E T H:

     WHEREAS, Sithe, Genco, Reliant Energy, Incorporated and Reliant Energy
Power Generation, Inc. are Parties to that certain Purchase Agreement, dated
of as February 19, 2000 (the "Purchase Agreement");

     WHEREAS, it is the intention of the parties hereto to transfer the
Acquired Assets (as defined in the Purchase Agreement) (other than the Real
Property) by the execution and delivery of this Agreement.

     NOW, THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and intending to be legally bound, the Sithe Entities and
Assignee hereby agree as follows:

     1.   Capitalized terms which are used in this Agreement but are not
defined herein shall have the respective meanings ascribed to such terms in the
Purchase Agreement.

     2.   Subject to paragraphs 4, 5 and 7 below, the Sithe Entities hereby
assign, sell, convey, transfer, deliver, and set over, free and clear of any
material Liens (as the term "material Liens" is used in Section 3.14 of the
Purchase Agreement), other than Permitted Liens, all of the Acquired Assets to
the Assignee.

     3.   The Sithe Entities are not making any representations or warranties
of any nature or kind with respect to the Acquired Assets, except as expressly
set forth in the Purchase Agreement.

     4.   [Notwithstanding anything to the contrary set forth herein, the
agreements listed on Annex A hereto are partially assigned and assumed
hereunder as set forth on such Annex.]

     5.   [Notwithstanding anything to the contrary set forth herein, the
assignments and assumptions described in paragraph 2 hereof shall not include
any rights or obligations arising under the agreements identified on Annex B
hereto.]

     6.   The Sithe Entities hereby agree with Assignee to execute and deliver
to Assignee such further documents and instruments as may be necessary or
reasonably requested by Assignee to confirm and perfect the assignment and
transfer to Assignee of the rights and obligations under the Purchase Agreement
with respect to those certain Acquired Assets identified herein.

     7.   To the extent that any rights of the Sithe Entities with respect to
any of the Acquired Assets may not be assigned without the consent of another
Person, which consent has not been obtained by the Closing Date, this Agreement
shall not constitute an assignment of the same, if an attempted assignment
would constitute a breach thereof or be unlawful. The Sithe Entities and
Assignee agree that if any consent to an assignment of any Contract included in
the Acquired Assets shall not be obtained or if any attempted assignment would
be ineffective or would impair Assignee's rights and obligations under the
Contract in question so that Assignee would not in effect acquire the benefit
of all such rights and obligations, the Sithe Entities, at Assignee's option,
shall either (a) to the maximum extent permitted by law, appoint Assignee to be
the agent of the Sithe Entities with respect to any such Contract or (b) to the
maximum extent permitted by law and such Contract, enter into such reasonable
arrangements with Assignee or take such other actions as are necessary to
provide Assignee with the same or substantially similar rights and obligations
under such Contracts as Assignee may reasonably request.

     8.   Any provision of this Agreement held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining
provisions hereof. The invalidity of a particular provision in a particular
jurisdiction shall not invalidate such provision in any other jurisdiction.

     9.   In the event that any provision of this Agreement is construed to
conflict with a provision of the Purchase Agreement, the provision in the
Purchase Agreement shall be deemed controlling.

     10.  This Agreement shall bind and shall inure to the benefit of the
respective parties and their permitted successors.

     11.  This Agreement shall be construed and enforced in accordance with the
laws of the State of New York without giving effect to the choice of law
principles thereof that would require the application of the laws of a
jurisdiction other than New York.

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