Value ("NAV") per unit will be determined daily for each unit outstanding of the
Stock Fund. The return earned by the Stock Fund will represent a combination of
the dividends paid on the shares of Sponsor Stock held by the Stock Fund, gains

on their face that the actions to be taken under those directions would be
prohibited by the foregoing fiduciary duty rules or would be contrary to the
terms of the Plan or this Agreement.

          (iii) Execution of Purchases and Sales.  (A) Purchases and sales of
                --------------------------------

shares required to be purchased or sold on such day; or

                    (2) If the Trustee is unable to purchase or sell the total
number of shares required to be purchased or sold on such day as a result of
market conditions; or

                    (3) If the Trustee is prohibited by the Securities and
Exchange Commission, the New York Stock Exchange, or any other regulatory body
from purchasing or selling any or all of the shares required to be purchased or
sold on such day.

In the event of the occurrence of the circumstances described in (1), (2), or
(3) above, the Trustee shall purchase or sell such shares as soon as possible
thereafter and shall determine the price of such purchases or sales to be the

                                       8

 
average purchase or sales price of all such shares purchased or sold,
respectively. The Trustee may follow directions from the Named Fiduciary to

share of Sponsor Stock. Any change in such remuneration may be made only by a
signed agreement between Sponsor and Trustee.

               (ii) Following the procedures set forth in Department of Labor
Prohibited Transaction Class Exemption 86-128, the Trustee will provide the
Sponsor with the following documents: (1) a description of FBSI's brokerage
placement practices; (2) a copy of PTCE 86-128; and (3) a form by which the
Sponsor may terminate this authorization to use a broker affiliated with the
Trustee. The Trustee will provide the Sponsor with this termination form
annually, as well as an annual report which summarizes all securities
transaction-related charges incurred by the Plan, and the Plan's annualized
turnover rate.

               (iii) Any successor organization of FBSI, through reorganization,
consolidation, merger or similar transactions, shall, upon consumption of such
transaction, become the successor broker in accordance with the terms of this
authorization provision.

               (iv) The Trustee and FBSI shall continue to rely on this
authorization provision until notified to the contrary. The Sponsor reserves the
right to terminate this authorization upon sixty (60) days written notice to
FBSI (or its successor) and the Trustee, in accordance with Section 11 of this
Agreement.

          (iv) Securities Law Reports.  The Named Fiduciary shall be responsible
               ----------------------

          (v)  Voting and Tender Offers.  Notwithstanding any other provision of
               ------------------------                                         
this Agreement the provisions of this Section shall govern the voting and

                    (1) When the issuer of the Sponsor Stock prepares for any
annual or special meeting, the Sponsor shall notify the Trustee ten (10) days in
advance of the intended record date and shall cause a copy of all materials to
be sent to the Trustee. Based on these materials the Trustee shall prepare a
voting instruction form. At the time of mailing of notice of each annual or
special stockholders' meeting of the issuer of the Sponsor Stock, the Sponsor
shall cause a copy of the notice and all proxy solicitation materials to be sent
to each Plan Participant with an interest in Sponsor Stock held in the Trust,
together with the foregoing voting instruction form to be returned to the
Trustee or its designee. The form shall show the proportional interest in the
number of full and fractional shares of Sponsor Stock credited to the
Participant's accounts held in the Stock Fund. The Sponsor shall provide the
Trustee with a copy of any materials provided to the Participants and shall
certify to the Trustee that the materials have been mailed or otherwise sent to
Participants.

                    (2) Each Participant with an interest in the Stock Fund
shall have the right to direct the Trustee as to the manner in which the Trustee
is to vote (including not to vote) that number of shares of Sponsor Stock
reflecting such Participant's proportional interest in the Stock Fund (both
vested and unvested). Directions from a Participant to the Trustee concerning
the voting of Sponsor Stock shall be communicated in writing, or by mailgram or
similar means. These directions shall be held in confidence by the Trustee and
shall not be divulged to the Sponsor, or any officer or employee thereof, or any
other person. Upon its receipt of the directions, the Trustee shall vote the
shares of Sponsor Stock reflecting the Participant's proportional interest in
the Stock Fund as directed by the Participant. The Trustee shall not vote shares
of Sponsor Stock reflecting a Participant's proportional interest in the Stock
Fund for which it has received no direction from the Participant.

                    (3) The Trustee shall vote that number of shares of Sponsor
Stock not credited to Participants' accounts in the same proportion on each
issue as it votes those shares credited to Participants' accounts for which it
received voting directions from Participants.

               (B) Tender Offers.
                   ------------- 

                                       10

 
                    (1) Upon commencement of a tender offer for any securities
held in the Trust that are Sponsor Stock, the Sponsor shall notify each Plan
Participant with an interest in such Sponsor Stock of the tender offer and
utilize its best efforts to timely distribute or cause to be distributed to the
Participant the same information that is distributed to shareholders of the
issuer of Sponsor Stock in connection with the tender offer, and, after
consulting with the Trustee, shall provide and pay for a means by which the
Participant may direct the Trustee whether or not to tender the Sponsor Stock
reflecting such Participant's proportional interest in the Stock Fund (both
vested and unvested). The Sponsor shall provide the Trustee with a copy of any
material provided to the Participants and shall certify to the Trustee that the
materials have been mailed or otherwise sent to Participants.

                    (2) Each Participant shall have the right to direct the
Trustee to tender or not to tender some or all of the shares of Sponsor Stock
reflecting such Participant's proportional interest in the Stock Fund (both
vested and unvested). Directions from a Participant to the Trustee concerning
the tender of Sponsor Stock shall be communicated in writing, or by mailgram or
such similar means as is agreed upon by the Trustee and the Sponsor under the
preceding paragraph. These directions shall be held in confidence by the Trustee
and shall not be divulged to the Sponsor, or any officer or employee thereof, or
any other person except to the extent that the consequences of such directions
are reflected in reports regularly communicated to any such persons in the
ordinary course of the performance of the Trustee's services hereunder. The
Trustee shall tender or not tender shares of Sponsor Stock as directed by the
Participant. The Trustee shall not tender shares of Sponsor Stock reflecting a
Participant's proportional interest in the Stock Fund for which it has received
no direction from the Participant.

                    (3) The Trustee shall tender that number of shares of
Sponsor Stock not credited to Participants' accounts in the same proportion as
the total number of shares of Sponsor Stock credited to Participants' accounts
for which it has received instructions from Participants.

                    (4) A Participant who has directed the Trustee to tender
some or all of the shares of Sponsor Stock reflecting the Participant's
proportional interest in the Stock Fund may, at any time prior to the tender
offer withdrawal date, direct the Trustee to withdraw some or all of the
tendered shares reflecting the Participant's proportional interest, and the
Trustee shall withdraw the directed number of shares from the tender offer prior
to the tender offer withdrawal deadline. Prior to the withdrawal deadline, if
any shares of Sponsor Stock not credited to Participants' accounts have been
tendered, the Trustee shall redetermine the number of shares of Sponsor Stock
that would be tendered under Section 5(e)(v)(B)(3) if the date of the foregoing
withdrawal were the date of determination, and withdraw from the tender offer
the number of shares of Sponsor Stock not credited to Participants' accounts
necessary to reduce the amount of tendered Sponsor Stock not credited to

                                       11

 
Participants' accounts to the amount so redetermined. A Participant shall not be
limited as to the number of directions to tender or withdraw that the
Participant may give to the Trustee.

                    (5) A direction by a Participant to the Trustee to tender
shares of Sponsor Stock reflecting the Participant's proportional interest in
the Stock Fund shall not be considered a written election under the Plan by the
Participant to withdraw, or have distributed, any or all of his withdrawable
shares. The Trustee shall credit to each proportional interest of the
Participant from which the tendered shares were taken the proceeds received by
the Trustee in exchange for the shares of Sponsor Stock tendered from that
interest. Pending receipt of directions (through the Administrator) from the
Participant or the Named Fiduciary, as provided in the Plan, as to which of the
remaining investment options the proceeds should be invested in, the Trustee
shall invest the proceeds in the Mutual Fund described in Schedule "C".

          (vi) Shares Credited.  For all purposes of this Section, the number of
               ---------------                                                  
shares of Sponsor Stock deemed "credited" or "reflected" to a Participant's
proportional interest shall be determined as of the last preceding valuation
date.  The trade date is the date the transaction is valued.

          (vii) General.  With respect to all rights other than the right to
                -------                                                     
vote, the right to tender, and the right to withdraw shares previously tendered,
in the case of Sponsor Stock credited to a Participant's proportional interest
in the Stock Fund, the Trustee shall follow the directions of the Participant
and if no such directions are received, the directions of the Named Fiduciary.
The Trustee shall have no duty to solicit directions from Participants.  With
respect to all rights other than the right to vote and the right to tender, in
the case of Sponsor Stock not credited to Participants' accounts, the Trustee
shall follow the directions of the Named Fiduciary.

          (viii) Conversion.  All provisions in this Section 5(e) shall also
                 ----------                                                 
apply to any securities received as a result of a conversion of Sponsor Stock.

        (f)    Notes. The Administrator shall act as the Trustee's agent for
               -----                                                        
Participant loan notes and as such shall (i) collect and remit all principal and
interest payments to the Trustee and (ii) keep the proceeds of such loans
separate from the other assets of the Administrator and clearly identify such
assets as Plan assets.  To originate a Participant loan, the Plan Participant
shall direct the Trustee as to the term and amount of the loan to be made from
the Participant's individual account.  Such directions shall be made by Plan
Participants by use of the telephone exchange system maintained for such purpose
by the Trustee or its agent.  The Trustee shall determine, based on the current
value of the Participant's account on the date of the request and any guidelines
provided by the Sponsor, the amount available for the loan.  Based on the
monthly interest rate supplied by the Sponsor in accordance with the terms of
the Plan, the Trustee shall advise the Participant of such interest rate, as
well as the installment payment amounts.  

                                       12

 
The Trustee shall distribute the loan note with the proceed check to the
Participant and obtain spousal consent if applicable. The Trustee also shall
distribute written truth-in-lending disclosure to the Participant. To facilitate
recordkeeping, the Trustee may destroy the original of any promissory note made
in connection with a loan to a Participant under the Plan, provided that the
Trustee first creates a duplicate by a photographic or optical scanning or other
process yielding a reasonable facsimile of the promissory note and the Plan
Participant's signature thereon, which duplicate may be reduced or enlarged in
size from the actual size of the original promissory note.

provision of the recordkeeping and administrative services set forth in this
Section 6 shall be conditioned on the Sponsor delivering to the Trustee a copy

or loss, and general expense, and of any other transactions attributable to the

Authorization Letters in the form of Schedules "D" and "E" attached hereto or on
a Plan Designation Form in accordance with Schedule "H" attached hereto or such
other individuals or persons as the Sponsor may notify the Trustee in writing.

        (b)     Directions from Sponsor or Administrator. Whenever the Sponsor

Fidelity Institutional Retirement
Services Company

Boston, MA  02109
                                 [Name of Plan]
                                 --------------

Dear Ms. McCarthy:

     In accordance with your request, this letter sets forth our opinion with
respect to the qualified status under section 401(a) of the Internal Revenue
Code of 1986 (including amendments made by the Employee Retirement Income
Security Act of 1974) (the "Code"), of the [name of plan], as amended to the
date of this letter (the "Plan").

     The material facts regarding the Plan as we understand them are as follows.
The most recent favorable determination letter as to the Plan's qualified status
under section 401(a) of the Code was issued by the [location of Key District]
District Director of the Internal Revenue Service and was dated [date] (copy
enclosed).  The version of the Plan submitted by [name of company] (the
"Company") for the District Director's review in connection with this
determination letter did not contain amendments made effective as of [date].
These amendments, among other matters, [brief description of amendments].
[Subsequent amendments were made on [date] to amend the provisions dealing with
[brief description of amendments].]

     The Company has informed us that it intends to submit the Plan to the
[location of Key District] District Director of the Internal Revenue Service and
to request from him a favorable determination letter as to the Plan's qualified
status under section 401(a) of the Code.  The Company may have to make some
modifications to the Plan at the request of the Internal Revenue Service in
order to obtain this favorable determination letter, but we do not expect any of
these modifications to be material.  The Company has informed us that it will
make these modifications.

     Based on the foregoing statements of the Company and our review of the
provisions of the Plan, it is our opinion that the Internal Revenue Service will
issue a favorable determination letter as to the qualified status of the Plan,
as modified at the request of the Internal Revenue Service, under section 401(a)
of the Code, subject to the customary condition that continued qualification of
the Plan, as modified, will depend on its effect in operation.

     Furthermore, in that the assets are in part invested in common stock issued
by the Company or an affiliate, it is our opinion that the Plan is an "eligible
individual account plan" (as defined under Section 407(d)(3) of ERISA) and that
the shares of common stock of the Company held and to be purchased under the
Plan are "qualifying employer securities" (as defined under Section 407(d)(5) of
ERISA).  Finally, it is our opinion that interests in the Plan are not required
to be registered under the Securities Act of 1933, as amended, or, if such
registration is required, that such interests are effectively registered under
said Act.

                              Sincerely,

                              [name of law firm]
                              By[signature]

                         TELEPHONE EXCHANGE PROCEDURES
                         -----------------------------


The following telephone exchange procedures are currently employed by Fidelity
Institutional Retirement Services Company (FIRSCO).

Telephone exchange hours are 8:30 a.m. (ET) to 8:00 p.m. (ET) on each business
day.  A "business day" is any day on which the New York Stock Exchange is open.
The Trustee will prepare and mail to the Participant, a confirmation of the
transactions (exchanges and changes to investment mix elections) within five (5)
business days of the Participants instructions.


FIRSCO reserves the right to change these telephone exchange procedures at its
discretion.

                                  Mutual Funds
                                  ------------

    Exchanges Between Mutual Funds
    ------------------------------

    Participants may call on any business day to exchange between the mutual
    funds.  If the request is received before 4:00 p.m. (EST), it will receive
    that day's trade date.  Calls received after 4:00 p.m. (EST) will be
    processed on a next day basis.


                               Sponsor Stock Fund
                               ------------------

 I.  Exchanges Between Mutual Funds and Sponsor Stock Fund
     -----------------------------------------------------

     Participants may call on any business day to exchange between the mutual
     funds and the Sponsor Stock Fund.  If the request is received before 4:00
     p.m. (ET), it will receive that day's trade date.  Calls received after
     4:00 p.m. (ET) will be processed on a next day basis.


II.  Exchange Restrictions
     ---------------------

     It is the intention of the Trustee to maintain a sufficient liquidity
     reserve in the Sponsor Stock Fund to meet exchange, redemption or
     withdrawal requests.  However, if there is insufficient liquidity in the
     Sponsor Stock Fund to allow for same day exchanges, the Trustee will be
     required to sell shares of Sponsor Stock to meet the exchange requests.  If
     this occurs, the subsequent exchange into other Plan investment options
     will take place five (5) business days later.  This allows for settlement
     of the stock trade at the custodian and the corresponding transfer to
     Fidelity.
