as applicable, which equitable relief shall be granted without bond or proof of
damages, and the receiving Party shall not plead in defense that there would be
an adequate remedy at law.

under Section 7.1.(b) has occurred, the breaching Party shall nonetheless comply
with this Section 7.2 pending the resolution of the dispute. If it is determined
that no breach or Event of Default under Section 7.1(b) existed, the Party
alleging the default shall pay and reimburse the other Party for all reasonable
costs and expenses incurred by it to cure the alleged default.

             7.2.2 Upon the occurrence of an Event of Default, the
non-defaulting Party may (i) exercise all such rights and remedies as may be
available to it at law or equity including seeking to recover damages caused by

Interconnection Facilities or the Transmission System.

             7.2.3 Notwithstanding the foregoing, upon the occurrence of any

and conditions hereof.

material adverse impact on Pepco or the Transmission System, Pepco shall have
the right to take immediately reasonable steps and/or to exercise immediately
all remedies available under this Agreement, or at law or equity, including the
right, after providing as much notice as is practicable under the circumstances
and complying with the applicable FERC notice requirements regarding termination
of service, to disconnect the Station from the Transmission System.

final and binding on the Parties. Judgment on the award may be entered upon it
in any court having jurisdiction.

              -----------------------
or be construed to preclude, any Party from filing a petition or complaint with
FERC with respect to any arbitrable claim over which FERC has jurisdiction. In
such case, the other Party may request FERC to reject or to waive jurisdiction.
If FERC rejects or waives jurisdiction with respect to all or a portion of the
claim, the portion of the claim not so accepted by FERC shall be resolved
through arbitration, as provided in this Agreement. To the extent that FERC
asserts or accepts jurisdiction over the claim, the decision, finding of fact or
order of FERC shall be final and binding, subject to judicial review under the
Federal Power Act, and any arbitration proceedings that may have commenced with
respect to the claim prior to the assertion or acceptance of jurisdiction by
FERC shall be terminated.

         14.1  Assignment.
               ----------

              (a) Except as set forth in this Article 14, neither this Agreement
nor any of the rights, interests, or obligations hereunder shall be assigned by
either Party hereto, without the prior written consent of the other Party, which
consent shall not be unreasonably withheld or delayed.

                                       31

              (b) Subject to Section 14.2, upon ten (10) days prior written
notice to Generator, Pepco may assign this Agreement, and Pepco's rights,
interests and obligations hereunder, to (i) an Affiliate of Pepco that owns all
or part of Pepco's Transmission System or (ii) an independent system operator or
independent transmission company whose control over all or part of Pepco's
Transmission System has been approved by the FERC.

              (c) Subject to Section 14.2, Generator may (a) assign any of its
rights and obligations hereunder to an Affiliate to the extent necessary for the
Generator to qualify as an exempt wholesale generator under Section 32 of the
Public Utility Holding Company Act of 1935, as amended, and (b) assign,
transfer, pledge or otherwise dispose of its rights and interests hereunder to a
trustee, lending institution, or other Person for the purposes of financing or
refinancing the Station, including upon or pursuant to the exercise of remedies
under such financing or refinancing, or by way of assignments, transfers,
conveyances of dispositions in lieu thereof; provided, however, that no such
assignment shall relieve or in any way discharge Generator from the performance
of its duties and obligations under this Agreement. Pepco agrees to execute and
deliver, at Generator's expense, such documents as may be reasonably necessary
to accomplish any such assignment, transfer, conveyance, pledge or disposition
of rights hereunder for purposes of the financing or refinancing of the
Facility, so long as Pepco's rights under this Agreement are not thereby
altered, amended, diminished or otherwise impaired.

              (d) Subject to Section 14.2, either Party may assign this
Agreement to a successor to all or substantially all of the assets of such Party
by way of merger, consolidation, sale or otherwise, provided such successor
assumes in writing and becomes liable for all of such Party's duties and
obligations hereunder.

         14.2 Release of Rights and Obligations. No assignment, transfer,
              ---------------------------------
conveyance, pledge or disposition of rights, interests, duties or obligations
under this Agreement by a Party shall relieve that Party from liability and
financial responsibility for the performance thereof after any such transfer,
assignment, conveyance, pledge or disposition unless and until (i) the
transferee or assignee shall agree in writing to assume the obligations and
duties of that Party under this Agreement and to impose such obligations on
subsequent permitted transferees and assignees and (ii) the non-assigning Party
has consented in writing to such assumption and to a release of the assigning
Party from such liability, such consent not to be unreasonably withheld or
delayed.

         14.3 Change in Corporate Identity. If Generator terminates its
              ----------------------------
existence as a limited liability company entity by merger, acquisition, sale,
consolidation or otherwise, or if all or substantially all of Generator's assets
are transferred to another

                                       32
<PAGE>

person or business entity without complying with this Article 14, Pepco shall
have the right, enforceable in a court of competent jurisdiction, to enjoin
Generator's successor from using the Station in any manner that does not comply
with the requirements of this Agreement or that impedes Pepco's ability to carry
on its ongoing business operations.

         14.4 Successors and Assigns. This Agreement and all of the provisions
              ----------------------
hereof are binding upon, and inure to the benefit of, the Parties and their

                                 --------------

         Nothing in this Agreement shall prevent the Parties from utilizing the
services of subcontractors as they deem appropriate, provided, however, the
Parties agree that, where applicable, all said subcontractors shall comply with
the terms and conditions of this Agreement. The creation of any subcontract
relationship shall not relieve the hiring Party of any of its obligations under
this Agreement. Each Party shall be fully responsible to the other Party for the
acts and/or omission of any subcontractor it hires as if no subcontract had been
made. Any obligation imposed by this Agreement upon the Parties, where
applicable, shall be equally binding upon and shall be construed as having
application to any subcontractor. The Parties shall each be liable for,
indemnify, and hold harmless the other Party, their Affiliates and their
officers, directors, employees, agents, servants, and assigns from and against
any and all claims, demands, or actions, from the other Party's subcontractors;
and shall pay all costs, expenses and legal fees associated therewith and all
judgments, decrees and awards rendered therein. No subcontractor is intended to
be or shall be deemed a third-party beneficiary of this Agreement.

                            MISCELLANEOUS PROVISIONS
                            ------------------------

         18.1 Waiver. Except as otherwise provided in this Agreement, any
              ------
failure of a Party to comply with any obligation, covenant, agreement, or
condition herein may be waived by the Party entitled to the benefits thereof
only by a written instrument signed by the Party granting such waiver, but such
waiver or failure to insist upon strict compliance with such obligation,
covenant, agreement, or condition shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure.

         18.2 Labor Relations. The Parties agree to immediately notify the other
              ---------------
Party, verbally and then in writing, of any labor dispute or anticipated labor
dispute which may reasonably be expected to affect the operations of the other

         18.3 No Third Party Beneficiaries. Nothing in this Agreement is
              ----------------------------
intended to confer upon any other person except the Parties any rights or

persons in respect of any benefits that may be provided, directly or indirectly,
under any employee benefit plan or arrangement except as expressly provided for
thereunder.

         18.4 Governing Law. This Agreement shall be governed by and construed

         18.5 Counterparts. This Agreement may be executed in two or more
              ------------

         18.6 Interpretation. When a reference is made in this Agreement to an
              --------------
Article, Section, Schedule or exhibit, such reference shall be to an Article or
Section of, or Schedule or exhibit to, this Agreement unless otherwise
indicated. The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Whenever the words "include", "includes" or
"including" are used in this Agreement, they shall be deemed to be followed by
the words "without limitation" or equivalent words. The words "hereof", "herein"
and "hereunder" and words of similar import when used in this Agreement shall
refer to this Agreement as a whole and not to any particular provision of this
Agreement. The definitions contained in this Agreement are applicable to the
singular as well as the plural forms of such terms and to the masculine as well
as to the feminine and neuter genders of such term. Unless otherwise expressly
stated otherwise herein, the word "day" shall mean any calendar day including
weekends and holidays. Any agreement, instrument, statute, regulation, rule or
order defined or referred to herein or in any agreement or instrument that is
referred to herein means such agreement, instrument, statute, regulation, rule
or order as from time to time amended, modified or supplemented, including (in
the case of agreements or instruments) by waiver or consent and (in the case of
statutes, regulations, rules or orders) by succession of comparable successor
statutes, regulations, rules or orders and references to all attachments thereto
and instruments incorporated therein. References to a person are also to its
permitted successors and assigns. Each Party acknowledges that it has been
represented by counsel in connection with the review and execution of this
Agreement, and, accordingly, there shall be no presumption that this Agreement
or any provision hereof be construed against the Party that drafted this
Agreement.

         18.7 Jurisdiction and Enforcement. Each of the Parties irrevocably
              ----------------------------
submits to the exclusive jurisdiction of the federal and state courts of the
State of Maryland for the purposes of any suit, action or other proceeding
arising out of this Agreement or any transaction contemplated hereby. Each of
the Parties agrees to commence any action, suit or proceeding relating hereto
either in the federal courts of the State of Maryland or, if such suit, action
or proceeding may not be brought in such court for jurisdictional reasons, in
the state courts of the State of Maryland. Each of the Parties further agrees
that service of process, summons, notice or document by hand delivery or U.S.
registered mail at the address specified for such Party in Section 16.2 (or such
other address specified by such Party from time to time pursuant to Section
16.2) shall be effective service of process for any action,

                                       36
<PAGE>

suit or proceeding brought against such Party in any such court. Each of the
Parties irrevocably and unconditionally waives any objection to the laying of
venue of any action, suit or proceeding arising out of this Agreement or the
transactions contemplated hereby in the federal and state courts of the State of
Maryland and hereby further irrevocably and unconditionally waives and agrees
not to plead or claim in any such court that any such action, suit or proceeding
brought in any such court has been brought in an inconvenient forum.

         18.8 Entire Agreement. This Agreement, Asset Sale Agreement, the
              ----------------
Confidentiality Agreement and the Ancillary Agreements including the Exhibits,
Schedules, documents, certificates and instruments referred to herein or therein
and other contracts, agreements and instruments contemplated hereby or thereby,
embody the entire agreement and understanding of the Parties in respect of the
transactions contemplated by this Agreement. There are no restrictions,
promises, representations, warranties, covenants or undertakings other than
those expressly set forth or referred to herein or therein. This Agreement, the
Asset Sale Agreement and the Ancillary Agreements supersede all prior agreements
and understandings between the Parties with respect to the transactions
contemplated by this Agreement other than the Confidentiality Agreement.

         18.9 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. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the Parties shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the Parties as closely as possible to the fullest extent permitted by
applicable law in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible.

         18.10 Independent Contractor Status. Nothing in this Agreement shall be
               -----------------------------
construed as creating any relationship between Pepco and Generator other than
that of independent contractors.

         18.11 Conflicts. Except with respect to the amendments,
               ---------
indemnification, liability, default and remedies provisions contained herein or
as otherwise expressly provided herein, in the event of any conflict or
inconsistency between the terms of this Agreement and the terms of the Asset
Sale Agreement, the terms of the Asset Sale Agreement shall prevail.
