Section 4. CASH PROCEEDS OF SECURITY AGREEMENT COLLATERAL.
(a) COLLATERAL ACCOUNT. The Trustee will cause to be
established at The Bank of New York a cash collateral account (the "COLLATERAL
ACCOUNT"), which shall be a "securities account" (as defined in Section 8-501 of
the UCC) in respect of which the Trustee shall be the "entitlement holder" (as
defined in Section 8-102(a)(7) of the UCC), into which there shall be deposited
from time to time the cash Proceeds of any of the Security Agreement Collateral
(including Proceeds of insurance thereon) required to be delivered to the
Trustee pursuant hereto and into which the Company may from time to time deposit
any additional amounts that the Company wishes to pledge to the Secured Party as
additional collateral security hereunder. The balance from time to time in the
Collateral Account shall constitute part of the Security Agreement Collateral
hereunder and shall not constitute payment of the Secured Obligations until
applied as hereinafter provided. Except as expressly provided in the next
sentence, the Trustee shall remit the collected balance standing to the credit
of the Collateral Account to or upon the order of the Company as the Company
shall from time to time instruct in writing. However, at any time following the
occurrence and during the continuance of an Event of Default, the Trustee may
(and, if instructed by the Holders as specified in Section 8.11 of the
Indenture, shall) apply or cause to be applied (subject to collection) the
balance from time to time standing to the credit of the Collateral Account to
the payment of the Secured Obligations then due and payable in the manner
specified in Section 5.09. The balance from time to time in the Collateral
Account shall be subject to withdrawal only as provided herein.
(b) PROCEEDS OF INITIAL SELECT POWER SALES AGREEMENT AND
NORTHEAST UTILITIES GUARANTEE. If so requested by the Trustee at any time after
the acceleration of each Series of Bonds in accordance with the Indenture, the
Company shall instruct in writing all account debtors in respect of the Initial
Select Power Sales Agreement and Northeast Utilities Guarantee

to make all payments in respect thereof either (a) directly to the Trustee or
(b) to one or more other banks in the United States of America under
arrangements, in form and substance satisfactory to the Trustee, pursuant to
which the Company shall have irrevocably instructed such other bank (and such
other bank shall have agreed) to remit all proceeds of such payments directly to
the Trustee for deposit into the Collateral Account. All payments made to the
Trustee, as provided in the preceding sentence, shall be immediately deposited
in the Collateral Account. In addition to the foregoing, the Company agrees
that, at any time after the occurrence and during the continuance of an Event of
Default, if the Proceeds of any Security Agreement Collateral hereunder shall be
received by it, the Company shall as promptly as possible deposit such Proceeds
into the Collateral Account. Until so deposited, all such Proceeds shall be held
in trust by the Company for and as the property of the Trustee and shall not be
commingled with any other funds or property of the Company.
(c) INVESTMENT OF BALANCE IN COLLATERAL ACCOUNT. The cash
balance standing to the credit of the Collateral Account shall be invested from
time to time in such Permitted Investments as the Company shall determine, which
Permitted Investments shall be held in the name and be under the control of the
Trustee (and, if the Collateral Account is a securities account, credited to the
Collateral Account), PROVIDED that at any time after the occurrence and during
the continuance of an Event of Default, the Trustee (if instructed by the
Holders as specified in Section 8.11 of the Indenture) shall at any time and
from time to time liquidate any such Permitted Investments and apply or cause to
be applied the Proceeds thereof to the payment of the Secured Obligations then
due and payable in the manner specified in Section 5.09.
Section 5. FURTHER ASSURANCES; REMEDIES. In furtherance of the
grant of the pledge and security interest pursuant to Section 3, the Company
hereby agrees with the Secured Party as follows:
5.01 DELIVERY AND OTHER PERFECTION. The Company shall:
(a) give, execute, deliver, file, record, authorize or obtain
all such financing statements, notices, instruments, documents,
agreements or consents or other papers as may be necessary to create,
preserve, perfect or validate the security interest granted pursuant
hereto or to enable the Trustee to exercise and enforce its rights
hereunder with respect to such pledge and security interest, PROVIDED
that the Company may at any time have Security Agreement Collateral
with an aggregate market value not exceeding $500,000 or 1% of the
Company's total assets (as shown on the Company's most recent balance
sheet), whichever is greater, as to which the steps necessary to
perfect the security interest granted hereunder have not been
perfected;
(b) following the acceleration of each Series of Bonds then
outstanding, upon request of the Trustee, promptly notify (and the
Company hereby authorizes the Trustee so to notify) each account debtor

Northeast Utilities Guarantee that such Security Agreement Collateral
has been

assigned to the Trustee hereunder, and that any payments due or to
become due in respect thereof are to be made directly to the Trustee;
(c) without limiting the obligations of the Company under
Section 5.04 but subject to the proviso to paragraph (a) above, upon
the acquisition after the date hereof by the Company of any Equipment
covered by a certificate of title or ownership, cause the Trustee to be
listed as the lienholder on such certificate of title and take such
other steps as may be required under the law applicable to perfection
of a security interest in such property to perfect such security
interest, and within 60 days of the acquisition thereof deliver
evidence of the same to the Trustee;
(d) keep full and accurate books and records relating to the
Security Agreement Collateral, and stamp or otherwise mark such books
and records in order to reflect the security interests granted by this
Agreement; and
(e) permit representatives of the Trustee, upon reasonable
notice, at any time during normal business hours to inspect and make
abstracts from its books and records pertaining to the Security
Agreement Collateral, and permit representatives of the Trustee to be
present at the Company's place of business to receive copies of all
communications and remittances relating to the Security Agreement
Collateral, and forward copies of any notices or communications
received by the Company with respect to the Security Agreement
Collateral, all in such manner as the Trustee or its agent may require.
5.02 OTHER FINANCING STATEMENTS AND LIENS. Except as otherwise
permitted under Section 5.9 of the Indenture, the Company shall not file or
suffer to be on file, or authorize or permit to be filed or to be on file, in
any jurisdiction, any financing statement or like instrument with respect to any
of the Security Agreement Collateral in which the Trustee is not named as the
sole secured party.
5.03 PRESERVATION OF RIGHTS. The Secured Party shall not be
required nor have any duty or obligation to take steps necessary to preserve any
rights against prior parties to any of the Security Agreement Collateral.
5.04 SPECIAL PROVISIONS RELATING TO MOTOR VEHICLES. (a)
Subject to Section 5.01(a), the Company shall deliver to the Trustee originals
of the certificates of title or ownership for the Motor Vehicles owned by it
with the Trustee listed as lienholder or take such other action as may be
necessary under applicable law to perfect the security interest created
hereunder in all such Motor Vehicles.
(b) Without limiting the generality of the foregoing but
subject to the proviso to Section 5.01(a), upon the acquisition after the date
hereof by the Company of any Motor Vehicle, the Company shall deliver to the
Trustee originals of the certificates of title or ownership for such Motor
Vehicles, together with the manufacturer's statement of origin with the Trustee

Trustee's lien on such Motor Vehicles under applicable law; PROVIDED, however,
if the Motor Vehicle to be acquired is subject

-----------------------------------------------
<Page>
-7-
to a purchase money security interest, the Trustee shall be listed as a junior
lienholder to the Person holding such purchase money security interest, if so
permitted by such Person.
(c) Without limiting Section 5.10, the Company hereby appoints
the Trustee as its attorney-in-fact, effective the date hereof and terminating
upon the termination of this Agreement, solely for the purpose of (i) executing
on behalf of the Company ownership or title applications as provided to it for
filing with appropriate state agencies to enable Motor Vehicles now owned or
hereafter acquired by the Company to be retitled and the Trustee listed as
lienholder thereon, (ii) filing such applications with such state agencies and
(iii) executing such other documents and instruments on behalf of, and taking
such other action in the name of, the Company as necessary to accomplish the
purposes hereof (including, without limitation, the purpose of creating in favor
of the Trustee a perfected lien on the Motor Vehicles and exercising the rights
and remedies of the Trustee under Section 5.05). This appointment as
attorney-in-fact is irrevocable and coupled with an interest.
5.05 EXERCISE OF RIGHTS, ETC. Following the acceleration of
each Series of Bonds then outstanding:
(a) the Company shall assemble the Security Agreement
Collateral owned by it at such place or places, reasonably convenient
to both the Trustee and the Company;
(b) the Trustee may, but shall not be obligated to, make any
reasonable compromise or settlement deemed desirable with respect to
any of the Security Agreement Collateral and may extend the time of
payment, arrange for payment in installments, or otherwise modify the
terms of, any of the Security Agreement Collateral;
(c) the Trustee shall have all of the rights and remedies with
respect to the Security Agreement Collateral of a secured party under
the Uniform Commercial Code (whether or not said Code is in effect in
the jurisdiction where the rights and remedies are asserted) and such
additional rights and remedies to which a secured party is entitled
under the laws in effect in any jurisdiction where any rights and
remedies hereunder may be asserted, including, without limitation, the
right but not the obligation, to the fullest extent permitted by
applicable law, to exercise all voting, consensual and other powers of
ownership pertaining to the Security Agreement Collateral as if the
Trustee were the sole and absolute owner thereof (and the Company
agrees to take all such action as may be appropriate to give effect to
such right);
(d) the Trustee in its discretion may, in its name or in the
name of the Company or otherwise, demand, sue for, collect or receive
any money or property at any time payable or receivable on account of
or in exchange for any of the Security Agreement Collateral, but shall
be under no obligation to do so; and
(e) the Trustee may, upon ten Business Days' prior written
notice to the Company of the time and place, with respect to the
Security Agreement Collateral or any part thereof that shall then be or
shall thereafter come into the possession, custody or control of the
Trustee, sell, lease, assign or otherwise dispose of all or any part of
such
Northeast Generation Company Security Agreement
-----------------------------------------------
<Page>
-8-
Security Agreement Collateral, at such place or places as the Trustee
chooses, and for cash or for credit or for future delivery (without
thereby assuming any credit risk), at public or private sale, without
demand of performance or notice of intention to effect any such
disposition or of the time or place thereof (except such notice as is
required above or by applicable statute and cannot be waived), and the
Secured Party or anyone else may be the purchaser, lessee, assignee or
recipient of any or all of the Security Agreement Collateral so
disposed of at any public sale (or, to the extent permitted by law, at
any private sale) and thereafter hold the same absolutely, free from
any claim or right of whatsoever kind, including any right or equity of
redemption (statutory or otherwise), of the Company, any such demand,
notice and right or equity being hereby expressly waived and released
to the fullest extent permitted by law. The Trustee may, without notice
or publication, adjourn any public or private sale or cause the same to
be adjourned from time to time by announcement at the time and place
fixed for the sale, and such sale may be made at any time or place to
which the sale may be so adjourned.
The Proceeds of each collection, sale or other disposition under this Section
5.05 shall be applied in the manner specified in Section 5.09.
The Company recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, and applicable state
securities laws, the Trustee may be compelled, with respect to any sale of all
or any part of the Security Agreement Collateral, to limit purchasers to those
who will agree, among other things, to acquire the Security Agreement Collateral
for their own account, for investment and not with a view to the distribution or
resale thereof. The Company acknowledges that any such private sales may be at
prices and on terms less favorable to the Trustee than those obtainable through
a public sale without such restrictions, and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner and that the Trustee shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Security Agreement Collateral for the period of time necessary to permit the
respective issuer thereof to register it for public sale.
5.06 DEFICIENCY. If the Proceeds of sale, collection or other
realization of or upon the Security Agreement Collateral pursuant to Section
5.05 are insufficient to cover the costs and expenses of such realization and
the payment in full of the Secured Obligations, the Company shall remain liable
for any deficiency.
5.07 LOCATIONS; NAMES. Without at least 30 days' prior written
notice to the Trustee, the Company shall not change its location (as defined in
Section 9-307 of the UCC) or change its name from the name shown as its current
legal name on Annex 1.
5.08 PRIVATE SALE. The Secured Party shall not incur any
liability as a result of the sale of the Security Agreement Collateral, or any
part thereof, at any private sale pursuant to Section 5.05 conducted in
accordance with this Agreement and applicable law. The Company hereby waives any
claims against the Secured Party arising by reason of the fact that the price at
which the Security Agreement Collateral may have been sold at such a private
sale was less than the price that might have been obtained at a public sale or
was less than the aggregate amount of
Northeast Generation Company Security Agreement
-----------------------------------------------

the Secured Obligations, even if the Secured Party accepts the first offer
received and does not offer the Security Agreement Collateral to more than one
offeree, so long as the Secured Party acted in each case in accordance with this
Agreement and applicable law.
5.09 APPLICATION OF PROCEEDS. Except as otherwise herein
expressly provided and except as provided below in this Section 5.09, the
Proceeds of any collection, sale or other realization of all or any part of the
Security Agreement Collateral pursuant hereto, and any other cash at the time
held by the Trustee under Section 4 or this Section 5, shall be applied by the
Trustee:
FIRST, to the payment of the costs and expenses of such
collection, sale or other realization, including reasonable
out-of-pocket costs and expenses of the Trustee and the fees and
expenses of its agents and counsel, and all expenses incurred and
advances made by the Trustee in connection therewith;
NEXT, to the payment in full of the Secured Obligations, in
each case equally and ratably in accordance with the respective amounts
thereof then due and owing; and
FINALLY, to the payment to the Company, or the Company's
successors or assigns, or as a court of competent jurisdiction may
direct, of any surplus then remaining.
5.10 ATTORNEY-IN-FACT. Without limiting any rights or powers
granted by this Agreement to the Trustee while no Event of Default has occurred
and is continuing, upon the occurrence and during the continuance of any Event
of Default the Trustee is hereby appointed the attorney-in-fact of the Company
solely for the purpose of carrying out the provisions of this Section 5 and
taking any action and executing any instruments that are necessary or advisable
to accomplish the purposes hereof, which appointment as attorney-in-fact is
irrevocable and coupled with an interest. Without limiting the generality of the
foregoing, so long as the Trustee shall be entitled under this Section 5 to make
collections in respect of the Security Agreement Collateral, the Trustee shall
have the right and power but not the obligation to receive, endorse and collect
all checks made payable to the order of the Company representing any dividend,
payment or other distribution in respect of the Security Agreement Collateral or
any part thereof and to give full discharge for the same.
5.11 PERFECTION. Subject to Section 5.01(a), prior to or
concurrently with the execution and delivery of this Agreement, the Company
shall (i) file such financing statements and other documents in such offices as
necessary or desirable to perfect the security interests granted by Section 3 of
this Agreement and (ii) cause the Trustee to be listed as the lienholder on all
certificates of title or ownership relating to Motor Vehicles owned by the
Company. Without limiting the foregoing, the Company consents that UCC financing
statements may be filed describing the Security Agreement Collateral as "all
assets" or "all personal property" of the Company (PROVIDED that no such
description shall be deemed to modify the description of Security Agreement
Collateral set forth in Section 3).
5.12 TERMINATION. When all Secured Obligations shall have been
paid in full or otherwise terminated or defeased in full, in cash as provided in
the Indenture, this Agreement
Northeast Generation Company Security Agreement
-----------------------------------------------
<Page>
-10-
shall terminate, and the Trustee shall forthwith cause to be assigned,
transferred and delivered, against receipt but without any recourse, warranty or
representation whatsoever, any remaining Security Agreement Collateral and money
received in respect thereof, to or on the order of the Company. The Trustee
shall also authorize or execute and deliver, as applicable, to the Company upon
such termination such Uniform Commercial Code termination statements,
certificates for terminating the Liens on the Motor Vehicles and such other
documentation as shall be reasonably requested by the Company to effect the
termination and release of the Liens on the Security Agreement Collateral.
5.13 FURTHER ASSURANCES. The Company agrees that, from time to
time, the Company will execute and deliver such further documents and do such
other acts and things as are necessary in order fully to effect the purposes of
this Agreement.
5.14 RELEASE OF MOTOR VEHICLES. (a) So long as no Event of
Default shall have occurred and be continuing, upon the written request of the
Company, the Trustee shall execute and deliver to the Company such instruments
as the Company shall reasonably request to remove the notation of the Trustee as
lienholder on any certificate of title for any Motor Vehicle; PROVIDED that any
such instruments shall be delivered, and the release effective only upon receipt
by the Trustee of a certificate from the Company stating that the Motor Vehicle
the lien on which is to be released is to be sold or has suffered a casualty
loss (with title thereto passing to the casualty insurance company therefor in
settlement of the claim for such loss).
(b) RELEASE OF SECURITY AGREEMENT COLLATERAL OTHER THAN MOTOR

recipient at its "Address for Notices" specified pursuant to Section 1.4 of the

Section.
6.02 NO WAIVER. No failure on the part of the Secured Party to
exercise, and no course of dealing with respect to, and no delay in exercising,
any right, power or remedy hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise by the Secured Party of any right, power or
remedy hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. The remedies herein are cumulative and are
not exclusive of any remedies provided by law.
6.03 AMENDMENTS, ETC. The terms of this Agreement may be
waived, altered or amended only by an instrument in writing duly executed by the
Company and the Trustee. Any such amendment or waiver shall be binding upon the
