This AGREEMENT AND PLAN OF MERGER, dated as of December 11, 1998
(this "Agreement"), is made and entered into by and among THE NATIONAL GRID
GROUP PLC, a public limited company incorporated under the laws of England
and Wales with registration number 2367004 ("Parent"), IOSTA LLC, a
Massachusetts limited liability company which is directly and indirectly
wholly owned by Parent ("LLC"), and NEW ENGLAND ELECTRIC SYSTEM, a
Massachusetts business trust (the "Company").

WHEREAS, the Board of Directors of Parent and the Company and the
members of LLC have each determined that it is advisable and in the best
interests of their respective shareholders and members to consummate, and
have approved, the business combination transaction provided for herein in
which LLC would merge with and into the Company, with the Company being the
surviving entity (the "Merger"), pursuant to the terms and conditions of
this Agreement, as a result of which Parent will own, directly or
indirectly, all of the issued and outstanding common shares of the Company
(the "Company Shares");

WHEREAS, Parent, LLC and the Company desire to make certain
representations, warranties and agreements in connection with the Merger
and also to prescribe various conditions to the Merger;

NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth in this Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree as follows:

ARTICLE I
THE MERGER

1.01 The Merger. Upon the terms and subject to the conditions of this
Agreement, at the Effective Time (as defined in Section 1.02), LLC shall be
merged with and into the Company in accordance with Section 2 of
Chapter 182 and Section 59 of Chapter 156C of the Massachusetts General
Laws ("MGL"). At the Effective Time, the separate existence of LLC shall
cease and the Company shall continue as the surviving entity in the Merger.
The Company, after the Effective Time, is sometimes referred to herein as
the "Surviving Entity" and the Company and LLC are sometimes referred to
herein as the "Constituent Entities". The effect and consequences of the
Merger shall be as set forth in Article II.

1.02 Effective Time. Subject to the provisions of this Agreement, on
the Closing Date (as defined in Article III), a certificate of merger shall
be executed and filed by the Company and LLC with the Secretary of the
Commonwealth of Massachusetts (the "Massachusetts Secretary"). The Merger
shall become effective at the time of the filing of the certificate of
merger relating to the Merger with the Massachusetts Secretary, or at such
later time as is specified in the certificate of merger (such date and time
being referred to herein as the "Effective Time").

1.03 Effects of the Merger. At the Effective Time, the Agreement and
Declaration of Trust of the Company (the "Trust Agreement") as in effect
immediately prior to the Effective Time shall be the agreement and
declaration of trust of the Surviving Entity, until thereafter amended as
provided by law and such agreement and declaration of trust. Subject to
the foregoing, the additional effects of the Merger shall be as provided in
the applicable provisions of Section 2 of Chapter 182 of the MGL and
Section 62 of the Limited Liability Company Act of Massachusetts.

ARTICLE II
CONVERSION OF SHARES

2.01 Conversion of Capital Stock. At the Effective Time, by virtue of
the Merger and without any action on the part of the holder thereof:

(a) Membership Interests of LLC. Each one percent of the issued
and outstanding membership interests in LLC shall be converted into one
transferable certificate of participation or share of the Surviving Entity.

(b) Conversion of Company Shares.

(i) Cancellation of Treasury Shares and Shares Owned by
Parent and Subsidiaries. All Company Shares that are owned by the Company
as treasury shares (excluding shares held as treasury shares pursuant to
the New England Electric System Companies' Rabbi Trust effective January 1,
1994, amended October 3, 1994 and amended December 2, 1996 (the "Rabbi
Trust Shares")) and any Company Shares owned by Parent, LLC or any other
wholly owned Subsidiary (as defined in Section 10.11) of Parent shall be
canceled and retired and shall cease to exist and no cash or other
consideration shall be delivered in exchange therefor.

(ii) Conversion of Company Shares. Each Company Share
issued and outstanding immediately prior to the Effective Time (other than
shares to be canceled in accordance with Section 2.01(b)(i)) and each Rabbi
Trust Share shall be canceled and converted in accordance with the
provisions of this Section 2.01 into the right to receive cash in the
amount (the "Per Share Amount") of $53.75, as such amount may hereafter be
adjusted in accordance with Section 2.01(c) hereof (the "Merger
Consideration"), payable, without interest, to the holder of such Company
Share, upon surrender, in the manner provided in Section 2.02 hereof, of
the certificate formerly evidencing such share.

(c) Adjustment in Amount of Merger Consideration. In the event
that the Closing Date shall not have occurred on or prior to the date that
is the six (6) month anniversary of the date on which the Company
Shareholders' Approval is obtained (the "Adjustment Date"), the Per Share
Amount shall be increased, for each day after the Adjustment Date up to and
including the day which is one day prior to the Closing Date, by an amount
equal to $0.003288; provided, however that the Per Share Amount shall not
exceed $54.35.

2.02 Surrender of Shares. (a) Deposit with Paying Agent. Prior to
the Effective Time, Parent or LLC shall designate a bank or trust company
reasonably acceptable to the Company to act as agent (the "Paying Agent")
for the benefit of the holders of Company Shares in connection with the
Merger to receive the funds to which holders of Company Shares shall become
entitled pursuant to Section 2.01(b)(ii) (the "Exchange Fund"). From time
to time at, immediately prior to or after the Effective Time, Parent or LLC
shall make or cause to be made available to the Paying Agent immediately
available funds in amounts and at the times necessary for the payment of
the Merger Consideration upon surrender of Certificates (as defined in
Section 2.02(b)) in accordance with Section 2.02(b), it being understood
that any and all interest or other income earned on funds made available to
the Paying Agent pursuant to this Section 2.02(a) shall belong to and shall
be paid (at the time provided for in Section 2.02(e)) as directed by Parent
or LLC. Any such funds deposited with the Paying Agent by Parent shall be
invested by the Paying Agent as directed by Parent or LLC.

(b) Exchange Procedure. As soon as practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates (the "Certificates") which immediately prior to
the Effective Time represented outstanding Company Shares (the "Canceled
Shares") that were canceled and became instead the right to receive the
Merger Consideration pursuant to Section 2.01(b)(ii): (i) a letter of
transmittal in such form as Parent or LLC and the Company may reasonably
agree (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon actual delivery of
the Certificates to the Paying Agent) and (ii) instructions for effecting
the surrender of the Certificates in exchange for the Merger Consideration.
Upon surrender of a Certificate or Certificates to the Paying Agent for
cancellation (or to such other agent or agents as may be appointed by
Parent or LLC and are reasonably acceptable to the Company), together with
a duly executed letter of transmittal and such other documents as the
Paying Agent shall require, the holder of such Certificate shall be
entitled to receive the Merger Consideration in exchange for each Company
Share formerly evidenced by such Certificate which such holder has the
right to receive pursuant to Section 2.01(b)(ii). In the event of a
transfer of ownership of Canceled Shares which is not registered in the
transfer records of the Company, the Merger Consideration in respect of
such Canceled Shares may be given to the transferee thereof if the
Certificate or Certificates representing such Canceled Shares is presented
to the Paying Agent, accompanied by all documents required to evidence and
effect such transfer and by evidence satisfactory to the Paying Agent that
any applicable stock transfer taxes have been paid. At any time after the
Effective Time, each Certificate shall be deemed to represent only the
right to receive the Merger Consideration subject to and upon the surrender
of such Certificate as contemplated by this Section 2.02. No interest
shall be paid or will accrue on the Merger Consideration payable to holders
of Certificates pursuant to Section 2.01(b)(ii).

(c) No Further Ownership Rights in Company Shares. The Merger
Consideration paid upon the surrender of Certificates in accordance with
the terms of Section 2.01(b)(ii) shall be deemed to have been paid at the
Effective Time in full satisfaction of all rights pertaining to the Company
Shares represented thereby. From and after the Effective Time, the share
transfer books of the Company shall be closed and there shall be no further
registration of transfers thereon of the Company Shares which were
outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to Parent for any reason, they
shall be canceled and exchanged as provided in this Section 2.02.

(d) Lost, Stolen or Destroyed Certificates. In the event any
owner of any Certificate shall claim that such Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by
the owner of such Certificate and delivery of that affidavit to the Paying
Agent and, if required by Parent or LLC, the posting by such person of a
bond in customary amount as indemnity against any claim that may be made
against Parent LLC, the Company or the Surviving Entity with respect to
such Certificate, the Paying Agent will issue in exchange for such lost,
stolen or destroyed Certificate the Merger Consideration payable upon due
surrender of, and deliverable pursuant to this Section 2.02 in respect of,
the Company Shares to which such Certificate relates.

(e) Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the shareholders of the Company for one
(1) year after the Effective Time shall be delivered to the Surviving
Entity, upon demand, and any Shareholders of the Company who have not
theretofore complied with this Article II shall thereafter look only to the
Surviving Entity (subject to abandoned property, escheat and other similar
laws) as general creditors for payment of their claim for the Merger
Consideration payable upon due surrender of the Certificates held by them.
None of Parent, LLC or the Surviving Entity shall be liable to any former
holder of Company Shares for the Merger Consideration delivered to a public
official pursuant to any applicable abandoned property, escheat or similar
law.

2.03 Withholding Rights. Each of the Surviving Entity and Parent
shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of Company Shares such
amounts as it is required to deduct and withhold with respect to the making
of such payment under the Internal Revenue Code of 1986, as amended (the
"Code"), or any provision of state, local or foreign tax law, including the
tax laws of the United Kingdom; provided, however, that if such withholding
may be eliminated or reduced through the delivery of any certificate or
other documentation, each of the Surviving Entity and the Parent shall
provide each holder of Company Shares with a reasonable opportunity to
deliver such certificate or other documentation. To the extent that
amounts are so withheld by the Surviving Entity or Parent, as the case may
be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of Company Shares in respect of
which such deduction and withholding was made by the Surviving Entity or
Parent, as the case may be.

ARTICLE IV
REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to Parent and LLC as follows:

4.01 Organization and Qualification. (a) The Company is a voluntary
association duly organized, validly existing and in good standing under the
laws of the Commonwealth of Massachusetts and has full power, authority and
legal right to own its property and assets and to transact the business in
which it is engaged. Each of the Company's Subsidiaries is a corporation
duly organized or incorporated, validly existing and in good standing under
the laws of its jurisdiction of organization or incorporation and has full
corporate power and authority to conduct its business as and to the extent
now conducted and to own, use and lease its assets and properties, except
where failure to be so organized or incorporated, existing and in good
standing or to have such power and authority, individually or in the
aggregate, could not reasonably be expected to have a Company Material
Adverse Effect. As used in this Agreement, the term "Company Material
Adverse Effect" means a material adverse effect on the business, assets,
results of operations, condition (financial or otherwise) or prospects of
the Company and its Subsidiaries taken as a whole. Each of the Company and
its Subsidiaries is duly qualified, licensed or admitted to do business and
is in good standing in each jurisdiction in which the ownership, use or
leasing of its assets and properties, or the conduct or nature of its
business, makes such qualification, licensing or admission necessary,

designation) by the Federal government of the United States, any state in
the United States or any political subdivision thereof, or any foreign

the knowledge of the Company, no Company Nuclear Facility is as of the date

the MGL and the provisions of Article 59A of the Company's Trust Agreement
will not apply to this Agreement, the Merger or other transactions
contemplated hereby or thereby.

same functionality as such software records, stores, processes and presents
such calendar dates falling on or before December 31, 1999 other than such
interruptions in millenium functionality that could not, individually or in
the aggregate, reasonably be expected to result in a Company Material
Adverse Effect. The Company reasonably believes as of the date hereof that
the remaining cost of adaptions referred to in the foregoing sentence will
not exceed the amounts reflected in the Form 10-Q filed by the Company for
the quarter ended September 30, 1998.

Subsidiaries (other than LLC) is a corporation duly incorporated or
organized, validly existing and in good standing (with respect to
jurisdictions which recognize the concept of good standing) under the laws
of its jurisdiction of incorporation or organization and has full corporate
power and authority to conduct its business as and to the extent now
conducted and to own, use and lease its assets and properties, except for
where failure to be so incorporated, existing and in good standing (with

properties, or the conduct or nature of its business, makes such
qualification, licensing, admission or good standing necessary, except
where failure to be so qualified, licensed or admitted, individually or in
the aggregate, could not reasonably be expected to have a Parent Material
Adverse Effect. Parent has previously delivered to the Company correct and
complete copies of the memorandum and articles of association (or other
comparable charter documents) of Parent and NGC, and the Operating
Agreement of LLC (the "LLC Agreement") and has attached to such documents
copies of all resolutions and other documents required to be so attached.

no change in the number of issued Parent Ordinary Shares other than the
issuance of Parent Ordinary Shares pursuant to options or rights
outstanding as of such date to subscribe or purchase Parent Ordinary

validly issued and fully paid, and no Parent Ordinary Share is entitled to
preemptive rights, except as provided in Section 89 of the Companies ▇▇▇
▇▇▇▇, as amended (the "Companies Act"). Except pursuant to this Agreement,
and except as disclosed in Section 5.02 of the Parent Disclosure Letter, on
the date hereof there are no outstanding Options obligating Parent or any
of its Subsidiaries to issue or sell any Parent Ordinary Shares or to
grant, extend or enter into any Option with respect thereto.

respect to the voting of or the right to participate in dividends or other
earnings in respect of any shares of NGC.

(c) Except as disclosed in the Parent Reports filed prior to the
date of this Agreement or Section 5.02 of the Parent Disclosure Letter and
except for the right of the holder of the Special Share to require Parent
to redeem the Special Share pursuant to the Articles of Association of
Parent, there are no outstanding contractual obligations of Parent or any
of its Subsidiaries to repurchase, redeem or otherwise acquire any Parent
Ordinary Shares or any shares of NGC or to provide funds to, or make any
investment (in the form of a loan, capital contribution or otherwise) in,
NGC or any other person.

(d) Except as disclosed in the Parent Disclosure Letter, as
of the date of this Agreement, no bonds, debentures, notes or other

right to vote) (together, "Parent Voting Debt") on any matters on which
Parent Shareholders may vote are issued or are outstanding nor are there
any outstanding Options obligating Parent or any of its Subsidiaries to
issue or sell any Parent Voting Debt or to grant, extend or enter into any

transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Parent and all necessary action on the part

each of Parent and LLC enforceable against each of Parent and LLC in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

5.04 Non-Contravention; Approvals and Consents. (a) The execution and
delivery of this Agreement by each of Parent and LLC do not, and the
performance by each of Parent and LLC of its obligations hereunder and the
consummation of the Merger and other transactions contemplated hereby will
not, conflict with, result in a violation or breach of, constitute (with or
without notice or lapse of time or both) a default under, result in or give
to any person any right of payment or reimbursement, termination,
cancellation, modification or acceleration of, or result in the creation or
imposition of any Lien upon any of the assets or properties of Parent, LLC

authorization, consent or approval of, any Governmental Authority is
necessary for the execution and delivery of this Agreement by Parent or LLC
or the consummation by Parent or LLC of the Merger and other transactions

such Affected Employees and that have not been satisfied as of the Closing
Date under any welfare plan maintained for the Affected Employees
immediately prior to the Closing Date, and (ii) provide each Affected

7.08 No Solicitations. Prior to the Effective Time, the Company
agrees: (a) that neither it nor any of its Subsidiaries shall, and it
shall use its best efforts to cause its Representatives (as defined in
Section 10.11) not to, knowingly initiate, solicit or encourage, directly
or indirectly, any inquiries or any proposal or offer (including, without
limitation, any proposal or offer to its Shareholders) with respect to a
merger, consolidation or other business combination including the Company
or any of its significant Subsidiaries (as defined in Rule 1-02(W) of
Regulation S-X promulgated under the Exchange Act) (a "Company Significant
Subsidiary"), or any acquisition or similar transaction (including, without
limitation, a tender or exchange offer) involving the purchase of (i) all
or any significant portion of the assets of the Company and its
Subsidiaries taken as a whole, (ii) ten percent or more of the outstanding
Company Shares or (iii) 50% or more of the outstanding shares of the
capital stock of any Company Significant Subsidiary (any such proposal or
offer being hereinafter referred to as an "Alternative Proposal"), or
engage in any negotiations concerning, or provide any confidential
information or data to, or have any other discussions with, any person or
group relating to an Alternative Proposal, or otherwise knowingly
facilitate any effort or attempt to make or implement an Alternative
Proposal other than from Parent and its affiliates; (b) that it will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties with respect to any
Alternative Proposal; and (c) that it will notify Parent immediately if any
such inquiries, proposals or offers are received by, any such information
is requested from, or any such negotiations or discussions are sought to be
initiated or continued with, it or any of such persons; provided, however,
that, prior to receipt of the Company Shareholders' Approval, nothing
contained in this Section 7.08 shall prohibit the Board of Directors of the
Company from (i) furnishing information to (but only pursuant to a
confidentiality agreement in customary form and having terms and conditions
no less favorable to the Company than the Confidentiality Agreement (as
defined in Section 7.01)) or entering into discussions or negotiations with
any person or group that makes an unsolicited Alternative Proposal, if, and
only to the extent that, (A) the Board of Directors of the Company, based
upon advice of outside counsel with respect to fiduciary duties, determines
in good faith that such action is necessary for the Board of Directors to
act in a manner consistent with its fiduciary duties to Shareholders under
applicable law, (B) the Board of Directors of the Company has reasonably
concluded in good faith (after consultation with its financial advisors)
that the person or group making such Alternative Proposal will have
adequate sources of financing to consummate such Alternative Proposal and
that such Alternative Proposal is likely to be more favorable to the
Company's shareholders than the Merger, (C) prior to furnishing such
information to, or entering into discussions or negotiations with, such
person or group, the Company provides written notice to Parent to the
effect that it is furnishing information to, or entering into discussions
or negotiations with, such person or group, which notice shall identify
such person or group and the material terms of the Alternative Proposal in
reasonable detail, and (D) the Company keeps Parent promptly informed of
the status and all material information with respect to any such
discussions or negotiations; and (ii) to the extent required, complying
with Rule 14e-2 promulgated under the Exchange Act with regard to an
Alternative Proposal. Nothing in this Section 7.08 shall (x) permit the
Company to terminate this Agreement (except as specifically provided in
Article IX), (y) permit the Company to enter into any agreement with
respect to an Alternative Proposal for so long as this Agreement remains in
effect (it being agreed that for so long as this Agreement remains in
effect, the Company shall not enter into any agreement with any person or
group that provides for, or in any way knowingly facilitates, an
Alternative Proposal (other than a confidentiality agreement under the
circumstances described above)), or (z) affect any other obligation of the
Company under this Agreement.

7.09 Directors' and Officers' Indemnification and Insurance.

(a) Indemnification. To the extent, if any, not provided by an
existing right of indemnification or other agreement or policy, from and
after the Effective Time, Parent shall, or shall cause the Surviving Entity
to, to the fullest extent permitted by applicable law, indemnify, defend
and hold harmless each person who is now, or has been at any time prior to
the date hereof, or who becomes prior to the Effective Time, (x) an officer
or director or (y) an employee covered as of the date hereof (to the extent
of the coverage extended as of the date hereof) of the Company or of any
Company Subsidiary (each an "Indemnified Party," and collectively, the
"Indemnified Parties") against (i) all losses, expenses (including
reasonable attorney's fees and expenses), claims, damages or liabilities
or, subject to the first proviso of the next succeeding sentence, amounts
paid in settlement, arising out of actions or omissions occurring at or
prior to the Effective Time (and whether asserted or claimed prior to, at
or after the Effective Time) that are, in whole or in part, based on or
arising out of the fact that such person is or was a director, officer or
employee of the Company or any Company Subsidiary (the "Indemnified
Liabilities"), and (ii) all Indemnified Liabilities to the extent they are
based on or arise out of or pertain to the transactions contemplated by
this Agreement, in each case, to the extent permitted by the Trust
Agreement or the indemnification agreements set forth in Section 7.09 of
the Company Disclosure Letter. In the event of any such loss, expense,
claim, damage or liability (whether or not arising before the Effective
Time), (i) Parent shall, or shall cause the Surviving Entity to, pay the
reasonable fees and expenses of counsel selected by the Indemnified
Parties, which counsel shall be reasonably satisfactory to Parent or the
Surviving Entity, as appropriate, promptly after statements therefor are
received and otherwise advanced to such Indemnified Party upon request,
reimbursement of documented expenses reasonably incurred, in either case to
the extent not prohibited by the Trust Agreement or the indemnification
agreements set forth in Section 7.09 of the Company Disclosure Letter upon
receipt of an undertaking by or on behalf of such director or officer to
repay such amounts as and to the extent required by the Trust Agreement or
the indemnification agreements set forth in Section 7.09 of the Company
Disclosure Letter, (ii) the Surviving Entity shall cooperate in the defense
of any such matter and (iii) any determination required to be made with
respect to whether an Indemnified Party's conduct complies with the
standards set forth under the Trust Agreement or the indemnification
agreements set forth in Section 7.09 of the Company Disclosure Letter and
the certificate of incorporation or by-laws or similar governing documents
of the Surviving Entity shall be made by independent counsel mutually
acceptable to the Surviving Entity and the Indemnified Party; provided,
however, that the Surviving Entity shall not be liable for any settlement
effected without its written consent (which consent shall not be
unreasonably withheld) and provided further that no indemnification shall
be made if such indemnification is prohibited by the Trust Agreement or the
indemnification agreements set forth in Section 7.09 of the Company
Disclosure Letter.

(b) Insurance. For a period of six years after the Effective
Time, Parent and the Surviving Entity shall at Parent's election, cause to
be maintained in effect an extended reporting period for current policies
of directors' and officers' liability insurance for the benefit of such
persons who are currently covered by such policies of the Company on terms
no less favorable than the terms of such current insurance coverage or
provide tail coverage for such persons which provides such persons with
coverage for a period of six years for acts prior to the Effective Time on
terms no less favorable than the terms of such current insurance coverage.

(c) Successors. In the event the Surviving Entity or any of its
successors or assigns (i) consolidates with or mergers into any other
person or entity and shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (ii) transfers all or
substantially all of its properties and assets to any person or entity,
then and in either such case, proper provisions shall be made so that the
successors and assigns of the Surviving Entity, as applicable, shall assume
the obligations set forth in this Section 7.09.

(d) Survival of Indemnification. To the fullest extent
permitted by law, from and after the Effective Time, all rights to
indemnification as of the date hereof in favor of the employees, agents,
directors and officers of the Company and the Company Subsidiaries with
respect to their activities as such prior to the Effective Time, as
provided in the Trust Agreement or the respective certificates of
incorporation and by-laws or similar governing documents in effect on the
date hereof, or otherwise in effect on the date hereof, shall survive the
Merger and shall continue in full force and effect for a period of not less
than six years from the Effective Time.

(e) Benefit. The provisions of this Section 7.09 are intended
to be for the benefit of, and shall be enforceable by, each Indemnified
Party, his or her heirs and his or her representatives.

(f) Amendment of the Trust Agreement. Parent shall not, and
shall ensure that the Surviving Entity shall not, amend the Trust Agreement
to in any way limit the indemnification provided to the Indemnified Parties
under this Section 7.09.

7.10 Expenses. Except as set forth in Section 9.03, whether or not
the Merger is consummated, all costs and expenses incurred in connection
with the Merger and other transactions contemplated hereby shall be paid by
the party incurring such cost or expense, except that the filing fees in
connection with the filings required under the HSR Act, Exon ▇▇▇▇▇▇ (as
defined in Section 8.01(d) hereof) and the 1935 Act shall be paid by Parent
or LLC.

7.11 Brokers or Finders. The Company represents, as to itself and its
affiliates, that no agent, broker, investment banker, financial advisor or
other firm or person is or will be entitled to any broker's or finder's fee
or any other commission or similar fee in connection with any of the Merger
and other transactions contemplated by this Agreement except ▇▇▇▇▇▇▇ ▇▇▇▇▇,
whose fees and expenses will be paid by the Company in accordance with the
Company's agreement with such firm, and the Company shall indemnify and
hold Parent harmless from and against any and all claims, liabilities or
obligations with respect to any other such fee or commission or expenses
related thereto asserted by any person on the basis of any act or statement
alleged to have been made by the Company or its affiliates.

7.12 Anti-Takeover Statutes. If any "fair price", "moratorium",
"business combination", "control share acquisition" or other form of anti-
takeover statute or regulation shall become applicable to the Merger or
other transactions contemplated hereby, the Company and the members of the
Board of Directors of the Company shall grant such approvals and take such
actions consistent with their fiduciary duties and in accordance with
applicable law as are reasonably necessary so that the Merger and other
transactions contemplated hereby may be consummated as promptly as
practicable on the terms contemplated hereby and otherwise act to eliminate
or minimize the effects of such statute or regulation on the Merger and
other transactions contemplated hereby.

7.13 Public Announcements. Except as otherwise required by law or the
rules of any applicable securities exchange or national market system or
any other Regulatory Authority, so long as this Agreement is in effect,
Parent and the Company will not, and will not permit any of their
respective Subsidiaries or Representatives to, issue or cause the
publication of any press release or make any other public announcement with
respect to the Merger and other transactions contemplated by this Agreement
without the consent of the other party, which consent shall not be
unreasonably withheld. Parent and the Company will cooperate with each
other in the development and distribution of all press releases and other
public announcements with respect to the Merger and other transactions
contemplated hereby, and will furnish the other with drafts of any such
releases and announcements as far in advance as practicable.

7.14 Restructuring of Merger. It may be preferable to effectuate a
business combination between Parent and the Company by means of an
alternative structure to the Merger. Accordingly, if, prior to
satisfaction of the conditions contained in Article VIII hereto, Parent
proposes the adoption of an alternative structure that otherwise
substantially preserves for Parent and the Company the economic benefits of
the Merger and will not materially delay the consummation thereof, then the
parties shall use their respective best efforts to effect a business
combination among themselves by means of a mutually agreed upon structure
other than the Merger that so preserves such benefits; provided that prior
to closing any such restructured transaction, all material third party and
Governmental Authority declarations, filings, registrations, notices,
authorizations, consents or approvals necessary for the effectuation of
such alternative business combination shall have been obtained and all
other conditions to the parties' obligations to consummate the Merger and
other transactions contemplated hereby, as applied to such alternative
business combination, shall have been satisfied or waived.

representations or warranties contained any qualification or limitation as
to "materiality" or "Parent Material Adverse Effect," shall be true and
correct as so made as of the Closing Date, except to the extent expressly
given as of a specified date and except where the failure of such
representations and warranties to be so true and correct as so made does
not have and could not reasonably be expected to have, individually or in

effect on LLC, and Parent and LLC shall each have delivered to the Company

ARTICLE IX
TERMINATION, AMENDMENT AND WAIVER

9.01 Termination. This Agreement may be terminated, and the Merger
and other transactions contemplated hereby may be abandoned, at any time
prior to the Effective Time, whether prior to or after the Company
Shareholders' Approval or the Parent Shareholders' Approval (except as
otherwise provided in Section 9.01(c) below):

(a) By mutual written agreement of the Board of Directors of
Parent and the Company, respectively;

(b) By the Company or Parent, by written notice to the other, if
the Closing Date shall not have occurred on or before the date that is the
nine (9) month anniversary of the date the Company Shareholders' Approval
is obtained (the "Initial Termination Date"); provided, however, that the
right to terminate the Agreement under this Section 9.01(b) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been the cause of, or resulted in, the failure of the
Effective Time to occur on or before such date; and provided, further, that
(i) if on the Initial Termination Date the conditions to the Closing set
forth in Section 8.01(e)(i) shall not have been fulfilled but all other
conditions to the Closing shall be fulfilled or shall be capable of being
fulfilled, then the Initial Termination Date shall be extended for six (6)
months beyond the Initial Termination Date (the "Extended Termination
Date") and (ii) if on the Initial Termination Date or, if the Initial
Termination Date has been extended as provided in the immediately preceding
clause (i), the Extended Termination Date, a Financial Disruption (as
defined in Section 9.03(d)) shall have occurred and be continuing, then the
Company shall have the right, but not the obligation, to postpone the
Closing to a date not later than the date that is the six (6) month
anniversary of the Initial Termination Date or the Extended Termination
Date, as the case may be, provided that no postponement of the Closing made
as permitted by this Section 9.01(b)(ii) shall operate as or be deemed to
be a waiver of any or all of the provisions of Section 8.02;

(c) By the Company or Parent, by written notice to the other, if
(i) the Company Shareholders' Approval shall not have been obtained at a
duly held meeting of such Shareholders, including any adjournments thereof
or (ii) the Parent Shareholders' Approval shall not have been obtained at a
duly held meeting of such shareholders, including any adjournments thereof;

(d) By the Company or Parent, if any applicable state or federal
law or applicable law of a foreign jurisdiction or any order, rule or
regulation is adopted or issued that has the effect, as supported by the
written opinion of outside counsel for such party, of prohibiting the
Merger or other transactions contemplated hereby, or if any court of
competent jurisdiction or any Governmental Authority shall have issued a
nonappealable final order, judgment or ruling or taken any other action
having the effect of permanently restraining, enjoining or otherwise
prohibiting the Merger or other transactions contemplated hereby (provided
that the right to terminate this Agreement under this Section 9.01(d) shall
not be available to any party that has not defended such lawsuit or other
legal proceeding (including seeking to have any stay or temporary
restraining order entered by any court or other Governmental Authority
vacated or reversed)).

(e) By the Company upon ten (10) days' prior notice to Parent if
the Board of Directors of the Company determines in good faith, that
termination of this Agreement is necessary for the Board of Directors of
the Company to act in a manner consistent with its fiduciary duties to
Shareholders under applicable law by reason of an unsolicited Alternative
Proposal meeting the requirements of clauses (A) and (B) of Section 7.07
having been made; provided that

(A) The Board of Directors of the Company shall
determine based on advice of outside counsel with respect to the
Board of Directors' fiduciary duties that notwithstanding a
binding commitment to consummate an agreement of the nature of
this Agreement entered into in the proper exercise of its
applicable fiduciary duties, and notwithstanding all concessions
which may be offered by Parent in negotiation entered into
pursuant to clause (B) below, it is necessary pursuant to such
fiduciary duties that the directors reconsider such commitment as
a result of such Alternative Proposal, and

(B) prior to any such termination, the Company shall,
and shall cause its respective financial and legal advisors to,
negotiate with Parent to make such adjustments in the terms and
conditions of this Agreement as would enable the Company to
proceed with the Merger or other transactions contemplated hereby
on such adjusted terms;

and provided further that the Company's ability to terminate this Agreement
pursuant to this Section 9.01(e) is conditioned upon the concurrent payment
by the Company to Parent of any amounts owed by it pursuant to
Section 9.03(b);

(f) By the Company, by written notice to Parent, if (i) there
shall have been any material breach of any representation or warranty, or
any material breach of any covenant or agreement, of Parent hereunder
(other than a breach described in clause (ii)), and such breach shall not
have been remedied within twenty (20) days after receipt by Parent of
notice in writing from the Company, specifying the nature of such breach
and requesting that it be remedied; (ii) Parent shall fail to deliver or
cause to be delivered the amount of cash to the Paying Agent required
pursuant to Section 2.02(a) at a time when all conditions to Parent's
obligation to close have been satisfied or otherwise waived in writing by
Parent; or (iii) the Board of Directors of Parent shall withdraw or modify,
or resolve to withdraw or modify, in any manner adverse to the Company its
approval of the Merger and other transactions contemplated hereby or its
recommendation to its Shareholders regarding the approval of this
Agreement, the Merger or other transactions contemplated hereby.

(g) By Parent, by written notice to the Company, if (i) there
shall have been any material breach of any representation or warranty, or
any material breach of any covenant or agreement, of the Company hereunder,
and such breach shall not have been remedied within twenty (20) days after
receipt by the Company of notice in writing from Parent, specifying the
nature of such breach and requesting that it be remedied; or (ii) the Board
of Directors of the Company (A) shall withdraw or modify in any manner
adverse to Parent its approval of the Merger and other transactions
contemplated hereby or its recommendation to its shareholders regarding the
approval of this Agreement, the Merger and other transactions contemplated
hereby, (B) shall approve or recommend or take no position with respect to
an Alternative Proposal or (C) shall resolve to take any of the actions
specified in clause (A) or (B).

(h) By Parent, by written notice to the Company on or after the
twelve (12) month anniversary of the date on which the Company
Shareholders' Approval is obtained, if the Order of the SEC approving the
Merger under the 1935 Act (the "1935 Act Order") shall not have been issued
prior to the time such notice is given and Parent reasonably believes that
the 1935 Act Order is not likely to be issued on or prior to the Extended
Termination Date.

9.02 Effect of Termination. If this Agreement is validly terminated
by either the Company or Parent pursuant to Section 9.01, this Agreement
shall forthwith become null and void and there shall be no liability or
obligation on the part of either the Company, Parent or LLC (or any of
their respective Representatives or affiliates), except that the provisions
of this Section 9.02, Sections 7.10, 7.11 and 7.13, Section 9.03 and
Sections 10.09 and 10.10 shall continue to apply following any such
termination.

9.03 Termination Fees. (a) In the event that this Agreement is
terminated (i) by Parent pursuant to Section 9.01(g)(i) or Section 9.01(c)
as a result of the Company Shareholders' Approval not being obtained and at
such time no Alternative Proposal has been made and remains outstanding or
(ii) by the Company pursuant to Section 9.01(f)(i) or Section 9.01(c) as a
result of Parent Shareholders' Approval not being obtained, then in (A) the
event of termination pursuant to Section 9.01(g)(i) or Section 9.01(c) as a
result of the Company Shareholder's Approval not being obtained and at a
time when no Alternative Proposal remains outstanding the Company shall pay
to Parent and (B) in the event of termination pursuant to
Section 9.01(f)(i), or Section 9.01(c) as a result of Parent Shareholders'
Approval not being obtained, Parent shall pay to the Company, promptly (but
no later than five (5) business days after the date of termination of this
Agreement), cash in an amount equal to all documented out-of-pocket
expenses and fees incurred by the party arising out of, or in connection
with or related to, the Merger and other transactions contemplated hereby,
not in excess of $10 million (the "Out-of-Pocket Expenses").

(b) In the event that this Agreement is terminated (i) by the
Company pursuant to Section 9.01(f)(iii) or (ii) by Parent pursuant to
Section 9.01(g)(ii), and, in the case of a termination under clause (A) of
Section 9.01(g)(ii) is as a result of an action by the Board of Directors
of the Company prior to obtaining the Company Shareholders' Approval, then
(A) in the event of termination pursuant to Section 9.01(g)(ii), the
Company shall pay to Parent and (B) in the event of termination pursuant to
Section 9.01(f)(iii) as a result of an action by the Board of Directors of
the Parent prior to obtaining the Parent Shareholders' Approval, Parent
shall pay to the Company, (promptly but in each case no later than five (5)
business days after the date of termination of this Agreement) by wire
transfer of same day funds, a termination fee of $100,000,000, plus, in
each case, the terminating party's Out-of-Pocket Expenses.

(c) In the event that (i) this Agreement is terminated by the
Company pursuant to Section 9.01(e) or (ii) any person or group shall have
made an Alternative Proposal that has not been withdrawn and this Agreement
is terminated by Parent pursuant to Section 9.01(g)(i) or Section 9.01(c)
as a result of the Company Shareholders' Approval not being obtained or by
the Company pursuant to Section 9.01(b) and, in the case of this clause
(ii) only, a definitive agreement with respect to such Alternative Proposal
is executed within two years after such termination, then the Company shall
pay to Parent, by wire transfer of same day funds, either on the date
contemplated in Section 9.01(e) if applicable, or otherwise, within five
(5) business days after such termination, a termination fee of
$100,000,000, plus the Out-of-Pocket Expenses of Parent to the extent not
otherwise payable pursuant to Section 9.03(a) above.

(d) If this Agreement is terminated by the Company, pursuant to
Section 9.01(f)(ii) and the failure by Parent referred to in such Section
is because of the occurrence of any significant disruptions in the
financial or capital markets which make it impracticable for a company
having financial characteristics similar to those of Parent as of the date
of this Agreement to finance a transaction of the size and nature as that
contemplated hereunder on commercially reasonable financing terms that are
available as of the date of such financing (a "Financial Disruption"), then
Parent shall pay to the Company a termination fee of $100,000,000. The
parties hereby acknowledge that a failure by Parent to deliver or cause to
be delivered the appropriate amount of cash as a result of a Financial
Disruption shall not constitute a willful breach of any representation,
warranty, covenant or agreement of Parent hereunder.

(e) In the event this Agreement is terminated by Parent pursuant
to Section 9.01(h), then Parent shall pay the Company, in cash by wire
transfer of same day funds within five (5) business days of such
termination notice, a termination fee of $75,000,000 (the "Regulatory
Termination Fee") plus the Out-of-Pocket Expenses of the Company; provided,
however, that the Regulatory Termination Fee shall not be payable to the
Company if the failure to obtain the 1935 Act Order by the twelve (12)
month anniversary of the date on which the Company Shareholders' Approval
is obtained has been caused by breach of this Agreement by the Company
after the date hereof.

(f) Nature of Fees. The parties agree that the agreements
contained in this Section 9.03 are an integral part of the Merger and the
other transactions contemplated hereby and constitute liquidated damages
and not a penalty. The parties further agree that if any party is or
becomes obligated to pay a termination fee pursuant to Sections 9.03(b)-
(e), the right to receive such termination fee shall be the sole remedy of
the other party with respect to the facts and circumstances giving rise to
such payment obligation. If this Agreement is terminated by a party as a
result of a willful breach of a representation, warranty, covenant or
agreement by the other party, including a termination pursuant to Section
9.01(f)(ii) caused by reasons other than a Financial Disruption, the non-
breaching party may pursue any remedies available to it at law or in equity
and shall be entitled to recover any additional amounts thereunder.
