     trust  within  the  meaning  of the  Code;  provided  that  the  instrument
     establishing  such trust,  as amended  from time to time,  shall govern any
     investment therein, and is hereby made a part of this Trust Agreement as if

advice to any person in connection with the selection of such options.

2.3          AVAILABLE INVESTMENT FUNDS

The Named Fiduciary shall direct the Trustee as to (i) the Investment Funds the
Trust shall be invested in during the Participant recordkeeping reconciliation
period, and (ii) the Investment Funds in which Plan Participants and/or the
Sponsor may invest in, subject to the following limitations. The Named Fiduciary
may determine to offer as Investment Funds only (i) securities issued by the
investment companies advised by Fidelity Management and Research Company
("Mutual Funds"), (ii) notes evidencing loans to Plan Participants in accordance
with the terms of the Plan, and (iii) collective investment funds maintained by
the Trustee for qualified plans; provided, however, that the Trustee shall be
considered a fiduciary with investment discretion only with respect to Plan
assets that are invested in collective investment funds maintained by the
Trustee for qualified plans. The Investment Funds initially selected by the
Named Fiduciary are identified in Schedule A attached hereto. The Named
Fiduciary may add additional Investment Funds with the consent of the Trustee
and upon mutual amendment of Schedule A of this Trust Agreement. The Sponsor
hereby acknowledges that it has received from the Trustee a copy of the
prospectus for each Mutual Fund selected by the Named Fiduciary as a Plan
Investment Fund.

2.4          PARTICIPANT DIRECTION

Each Plan Participant shall direct the Trustee in which Investment Fund(s) to
invest the assets in the Participant's Separate Account as provided in the Plan.
Such directions may be made by Plan Participants by use of the telephone
exchange system maintained for such purposes by the Trustee or its agent, in
accordance with written telephone exchange guidelines set forth in the service
agreement between the Sponsor and Fidelity Management and Research Company (the
"Service Agreement"). In the event that the Trustee fails to receive a proper
direction, the assets shall be invested in the securities of the Mutual Fund set
forth for such purpose in the Service Agreement, until the Trustee receives a
proper direction. Additionally, in the event any assets in the Participant's
Separate Account are not subject to the Participant's investment direction, such
assets shall be invested as directed by the Sponsor in accordance with the
Service Agreement.

2.5          ADJUSTMENT OF CLAIMS

Subject to the consent of the Sponsor, the Trustee is empowered to compromise
and adjust any and all claims, debts, or obligations in favor of or against the
Trust, whether such claims

                                        5





be in litigation or not, upon such terms and conditions as it shall determine,
and to reduce the rate of interest on, to extend or otherwise modify, to
foreclose upon default, or otherwise to enforce any such claim, debt, or
obligation.

2.6          VOTING RIGHTS

At the time of mailing of notice of each annual or special stockholders' meeting
of any Mutual Fund, the Trustee shall send a copy of the notice and all proxy
solicitation materials to each Participant who has shares of the Mutual Fund
credited to the Participant's Separate Account, together with a voting direction
form for return to the Trustee or designee. The Participant shall have the right
to direct the Trustee as to the manner in which the Trustee is to vote the
shares credited to the Participant's Separate Account (both vested and
unvested), except as otherwise provided in this Section 2.6. The Trustee shall
vote the shares as directed by the Participant. The Sponsor shall have the right
to direct the Trustee as to the manner in which the Trustee is to vote the
shares of the Mutual Funds in the Trust during the Participant recordkeeping
reconciliation period and any shares credited to the Participant's Separate
Account which are not subject to Participant direction. With respect to all
rights other than the right to vote, the Trustee shall follow the directions of
the Named Fiduciary. The Trustee shall have no duty to solicit directions from
Participants or the Sponsor.

2.7          PARTICIPANT LOANS

If provided under the terms of the Plan, the Sponsor may direct the Trustee in
writing to establish a separate loan Investment Fund with respect to a
Participant and to transfer assets from any of the other Trust Funds to the
separate loan Investment Fund for the purpose of making loans to the Participant
as provided in the Plan. The Trustee shall be required to follow the directions
so given to it; provided, however, that the Trustee shall not be required to
follow any directions which would result in a breach of the Trustee's fiduciary
duties.

2.8          REGISTRATION OF SECURITIES; NOMINEES

The Trustee is empowered to register securities in its own name, or in the name
of its nominee, without disclosing the trust, or to hold the same in bearer
form, and to take title to other property in its own name or in the name of its
nominee without disclosing the trust; provided, however, that the Trustee shall
be responsible for the acts of its nominees.

                                        6





2.9          AGENTS, ATTORNEYS, ACTUARIES, AND ACCOUNTANTS

The Trustee is empowered to employ such agents, attorneys (including attorneys
who may be of counsel for the Sponsor), actuaries, and accountants as it may
deem necessary or proper in connection with its duties hereunder, and to
determine and pay the reasonable compensation and expenses of such agents,
attorneys, actuaries, and accountants.

2.10         DEPOSIT OF FUNDS

The Trustee is empowered to deposit funds, pending investment or distribution
thereof, in the commercial or, savings department of any bank, savings and loan
association or trust company supervised by the United States or a state or
agency thereof; and it is authorized to accept such regulations covering the
withdrawal of funds so deposited as it shall deem proper. The Trustee may
deposit all or any part of the Trust, including both principal and interest, in
the banking department of the Trustee (and any of its affiliates) and of any
other fiduciary or party-in-interest with respect to the Trust; provided,
however, that the deposits bear a reasonable rate of interest and are authorized
pursuant to the provisions of Section 408 of ERISA.

2.11         PAYMENT OF TAXES; INDEMNITY

The Trustee is empowered to pay out of the Trust, as a general charge thereon,
any and all taxes of whatsoever nature assessed on or in respect to the Trust;
provided, however, that, if the Sponsor shall notify the Trustee in writing that
in the opinion of its counsel any such tax is not lawfully assessed, the
Trustee, if so requested by the Sponsor, shall contest the validity of such tax
in any manner deemed appropriate by the Sponsor or its counsel. The word
"taxes", as used herein, shall be deemed to include any interest or penalties
assessed in respect to such taxes. Unless the Trustee first shall have been
indemnified to its satisfaction by the Sponsor, the Trustee shall not be
required to contest the validity of any tax, to institute, maintain, or defend
against any other action or proceeding, or to incur any other expense in
connection with the Trust, except to the extent that the Trust is sufficient
therefor.

2.12         RECORDS AND STATEMENTS

The Trustee shall keep accurate records of all receipts, disbursements, and
other transactions affecting the Trust which, together with the assets
comprising the Trust and all evidences thereof, shall be available for
inspection or for the purpose of making copies or reproductions thereof by the
Sponsor or any of its duly authorized representatives. The Trustee shall render
to the Sponsor at intervals agreed to by the Sponsor and the Trustee statements
of receipts and disbursements and of all transactions

                                        7





during the preceding interval affecting the Trust and a statement of all assets
held in the Trust and the investment performance or the Investment Funds.

2.13          AUTHORITY

The Trustee is authorized to execute and deliver any and all instruments and to
perform any and all acts which may be necessary or proper to enable it to
discharge its duties under this Trust Agreement and to carry out the powers and
authority conferred upon it. The Sponsor specifically acknowledges and
authorizes that affiliates of the Trustee may act as its agent in the
performance of ministerial, non-fiduciary duties under the Trust. The expenses
and compensation of such agent shall be paid by the Trustee.

2.14          COURT ACTION NOT REQUIRED

All the powers and authority herein conferred upon the Trustee shall be
exercised by it without the necessity of applying to any court for leave or
confirmation. No person, firm, or corporation dealing with the Trustee shall be
required to ascertain whether the Trustee shall have obtained the approval of
any court or of any person with respect to any action which it may propose to
take hereunder, but every such person, firm, or corporation shall be protected
in relying solely upon the deed, transfer, or assurance of the Trustee.

2.15          RELIANCE ON WRITTEN DIRECTIONS

Any written direction, request, approval, or other document signed in the name
of the Sponsor or the Administrator by a duly authorized individual shall be
conclusively deemed to constitute the written direction, request, approval, or
other document of the Sponsor or the Administrator and the Trustee shall not be
liable for any loss, or by reason of any breach, arising from the direction
unless it is clear on the direction's face that the actions to be taken under
the direction would be prohibited by the fiduciary duty rules of Section 404(a)
of ERISA or would be contrary to the terms of the Plan or this Trust Agreement.
The Trustee will be entitled to rely on the latest certificate it has received
from the Sponsor or Administrator as to any person or persons authorized to act
for the Sponsor or Administrator hereunder and to sign on behalf of the Sponsor
or Administrator any directions or instructions, until it receives from the
Sponsor or Administrator written notice that such authority has been revoked.

                                        8





2.16         TRUSTEE'S PERFORMANCE

In the exercise of any of the powers and authority herein conferred upon it, the
Trustee shall adhere at all times to the fiduciary standards established by
ERISA.

2.17          COUNSEL

The Trustee may consult with counsel selected by it, who may be of counsel for
the Sponsor, as to any matters or questions arising hereunder, and the opinion
of such counsel shall be full and complete authority and protection in respect
to any action taken, suffered, or omitted by the Trustee in good faith and in
accordance with the opinion of such counsel.

2.18          ANNUITY CONTRACTS

Notwithstanding any other provision of this Trust Agreement or the Plan to the
contrary, the Administrator shall retain all discretionary power relating to any
annuity contract acquired by or delivered to the Trustee. As directed by the
Administrator, the Trustee will acquire, hold and dispose of annuity contracts,
deliver the purchase price, and exercise any and all rights, privileges,
options, and elections under those policies. The Trustee will be fully

4.1          RESIGNATION OF THE TRUSTEE

Any Trustee acting hereunder may resign at any time by giving notice in writing
to the Sponsor at least 60 days before such resignation is to become effective,
unless the Sponsor shall accept as adequate a shorter notice.

4.2      REMOVAL OF THE TRUSTEE

If for any reason a vacancy should occur in the trusteeship, a successor Trustee
shall forthwith be appointed by the Sponsor. Any successor Trustee appointed

in writing accepting such appointment hereunder. Such successor Trustee

Trust, and shall have the same powers and duties with respect thereto, as are
hereby vested in the original Trustee. The predecessor Trustee shall execute all
such instruments and perform all such other acts as the successor Trustee or
Sponsor shall reasonably request to effectuate the provisions hereof. The
successor Trustee shall have no duty to inquire into the administration of the
Trust for any period prior to its succession.

The Sponsor reserves the right, at its sole discretion, from time to time to
amend the provisions of this Trust Agreement in any manner; provided, however,
that the powers, duties, and immunities of the Trustee under this Trust
Agreement shall not be substantively changed without its written approval. Any
such amendment shall be by written instrument executed by the Sponsor and
delivered to the Trustee, and may be made retroactively if in the opinion of the
Sponsor such amendment is necessary to enable the Plan and the Trust to meet the
requirements of the Code (including the regulations and rulings issued
thereunder) or the requirements of any governmental authority.

5.2          LIMITATION ON AMENDMENT

The Sponsor shall make no amendment to this Trust Agreement that results in the
      forfeiture or reduction of the accrued benefit of any Participant or
 Beneficiary. Notwithstanding the preceding sentence, nothing herein contained
    shall restrict the right to amend the provisions of this Trust Agreement
  relating to the administration of the Plan and the Trust. Moreover, no such
 amendment shall be made under this Article which shall permit any part of the
 Trust to revert to the Sponsor or any Related Company or to be used for or be
 diverted to purposes other than for the exclusive benefit of Participants and
Beneficiaries.

                                  MISCELLANEOUS


6.1          VALIDITY OF TRUST AGREEMENT

The validity of this Trust Agreement shall be determined and this Trust
Agreement shall be construed in accordance with the laws of the Commonwealth of
Massachusetts, except to the extent that they are superseded by Section 514 of
ERISA. The invalidity or illegality of any provision of this Trust Agreement
shall not affect the validity or legality of any other part hereof.

 6.2         NO GUARANTEES

Neither the Sponsor nor the Trustee guarantees the Trust from loss or
depreciation.

6.3           DUTY TO FURNISH INFORMATION

The Administrator, the Employers, and the Trustee shall furnish to any of the
others any documents, reports, returns, statements, or other information that
such other reasonably deems necessary to perform its duties imposed under the
Plan or this Trust Agreement or otherwise imposed by law.

6.4           FEDERAL INCOME TAX WITHHOLDING

The Trustee shall not be responsible for withholding federal and state income
tax from distributions unless the Administrator provides the Trustee with the
following information concerning each distribution:

(a)  The name,  address,  and social security number of the Participant (and the
     Participant's  spouse or other  Beneficiary if  applicable).  By forwarding
     such  information,  the  Administrator  shall  be  deemed  hereby  to  have
     certified the accuracy of such information.

(b)  A statement of the reason for the payment or distribution and directions as
     to the type of distribution (i.e. total qualified, periodic or non-periodic
     distribution) requested.

If the Administrator does not provide the Trustee with the above information,
the responsibility for withholding federal and state income taxes and the
reporting thereof shall remain with the Administrator.

6.5           PARTIES BOUND

This Trust Agreement shall be binding upon the parties hereto, all Participants,
and persons claiming under or through them pursuant to the Plan, and, as the
case may be, the heirs, executors, administrators, successors, and assigns of
each of them.

6.6           INDEMNIFICATION BY SPONSOR

The Sponsor shall indemnify and save harmless from and against any and all
liability to which the Trustee may be subjected by reason of any act or conduct
in its capacity as Trustee, including all expenses reasonably incurred in its
defense, except for losses or expenses resulting from the negligence or willful
misconduct of the Trustee or its affiliates.

6.7           BONDING REQUIREMENTS

Every fiduciary, except a bank or an insurance company, unless exempted by ERISA
and the regulations thereunder, shall be bonded in an amount not less than ten
percent of the funds such fiduciary handles; provided, however, that the minimum
bond shall be $1,000 and the maximum bond shall be $500,000. The amount of funds
handled shall be determined at the beginning of each Plan Year by the amount of
funds handled by such person, group, or class to be covered and their
predecessors, if any, during the preceding Plan year, or if there is no
preceding Plan Year, then by the amount of the funds to be handled during the
then current Plan Year. The bond shall provide protection to the Plan against
any loss by reason of acts of fraud or dishonesty by the fiduciary alone or in
connivance with others. The surety shall be a corporate surety company (as such
term is used in Section 412(a) (2) of ERISA), and the bond shall be in a form
approved by the Secretary of Labor. Notwithstanding anything to the contrary
contained in the Plan or this Trust Agreement, the cost of such bonds shall be
an expense of and may, at the election of the Sponsor, be paid from the Trust or
by the Sponsor.

6.8           SEPARATE TRUST OR FUND FOR EXISTING PLAN ASSETS

With the consent of the Trustee, an Employer may maintain a trust or fund
(including a group annuity contract) under the Plan separate from the Trust Fund
to hold Plan assets acquired prior to the effective date of this Trust Agreement
which are not among the available Investment Funds provided under Section 2.3.
The duties and responsibilities of the trustee of the separate trust
(hereinafter referred to as the "trustee") shall be provided by a separate trust
agreement between the Employer and the trustee.

Notwithstanding the preceding paragraph, the Trustee or an affiliate of the
Trustee may agree in writing to provide

                                       14





ministerial recordkeeping service for guaranteed investment contracts held in
the separate trust or fund. Any such guaranteed investment contract shall be
valued as directed by the Employer or the trustee.

The trustee shall be the owner of any insurance contract purchased prior to the
effective date of this Trust Agreement. Any such insurance contract must provide
that the proceeds will be payable to the trustee; provided, however, that the
trustee shall be required to pay over all proceeds of the contract to the
Participant's Beneficiary in accordance with the distribution provisions of the
Plan. Under no circumstances will the Trust Fund retain any part of the
proceeds. In the event of any conflict between the terms of the Plan and the
terms of any insurance contract held hereunder, the Plan provisions shall
control.

Any life insurance contracts held in the Trust Fund or in the separate trust
shall be subject to the provisions of Article IX of the Plan.
