                               WITNESSETH THAT:

     WHEREAS, Financial Institution desires to make a broad range of securities
brokerage services available to its customers; and

     WHEREAS, UVEST desires to provide Financial Institution's customers with
such brokerage services.

     NOW, THEREFORE, in consideration of the mutual covenants hereinafter set
forth, and other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto hereby covenant and agree as follows:

1. SERVICES

          1.1 Services To Be Performed By UVEST

     (a) UVEST will accept, establish and maintain cash and/or margin accounts
for customers of Financial Institution pursuant to the policies and guidelines
established by UVEST and in accordance with all applicable laws, regulations,
rules and procedures, including without limitation those of the Securities and
Exchange Act of 1934, as amended, and the National Association of Securities
Dealers, Inc.

     (b) UVEST will execute, clear and settle orders for accounts that have been
accepted by UVEST (the "Accounts"), but only insofar as such orders are
transmitted by the Account to UVEST. As used in this Agreement, the term
"securities" includes stocks, bonds (US Treasury, Municipal and Corporate),
mutual funds, unit investment trusts, and listed options, but does not include
commodities.

     (c) UVEST shall make available to the Accounts toll-free telephone service
and Internet access for placing orders and for customer service. That telephone
service shall be staffed by personnel of UVEST who may identify the services
provided as services of UVEST, a registered trademark of UVEST Financial
Services Group, Inc.

     (d) UVEST will prepare, print and mail to each Account at its address of
record on the books of UVEST confirmation information respecting the execution
of each order for the Account. Each such confirmation will display the name of
UVEST and the Clearing Agent.

     (e) UVEST will prepare, print and mail monthly statements to the Accounts
at their address of record on the books of UVEST (or quarterly statements if no
activity in an Account occurs during any quarter covered by such statement and
there is a cash balance or securities position in such Account). No statements
will be prepared for an account if there has been no activity and there is no
cash balance or security position. Each statement will display the name of
UVEST, the Clearing Agent and the Financial Institution.

     (f) UVEST will be responsible for the receipt of the customer securities,
delivery of customer securities, making and receiving payment therefor and
holding in custody and

                                       1

generally. It shall be the responsibility of UVEST to comply with any and all
prospectus delivery requirements with respect to Accounts that purchase
securities requiring such delivery.

     (g) All Accounts shall be maintained as accounts of UVEST or of UVEST's
designated Clearing Agent and UVEST will maintain books and records of all
transactions executed by Accounts through it in accordance with applicable law.

     (h) UVEST, in its sole judgment, reserves the right to reject any Account
or order thereof and to terminate any Account previously accepted by it as an
Account, which right will not be unreasonably exercised.

     (i) UVEST shall be responsible for providing annual dividend and
distribution information as contained in IRS Form 1087 and any other information
required to be reported to Accounts by Federal, state or local tax laws, rules
or regulations, but only with respect to events subsequent to the effective date
of this Agreement.

     (j) All transactions in any Account are to be considered cash transactions
until such time as UVEST has received and approved a duly and validly executed
margin agreement. UVEST is responsible for the operation of such margin accounts
in accordance with all-applicable laws, rules and regulations. UVEST shall have
complete authority and control over the terms, conditions and operations of
margin accounts and shall have the right, in its sole discretion, to modify the
margin requirements of any account.

     (k) UVEST may delegate any or all of its duties under this Section to a
clearing agent of its choice, which may, but is not required to be Pershing, a
division of Donaldson, Lufkin & Jenrette Securities Corporation (the "Clearing
Agent"). Pershing is the Clearing Agent on the date of this Agreement. UVEST
shall promptly notify the Financial Institution, in writing, of any change to
the Clearing Agent. That written notice shall constitute a representation and
warranty by UVEST to Financial Institution that such new Clearing Agent has the
facilities and holds all federal and state licenses and approvals required under
applicable laws and regulations to act as a Clearing Agent with respect to the
Accounts.

     (1) UVEST shall be responsible for managing the process whereby Financial
Institution's customers' accounts are to be automatically debited or credited,
as appropriate, for the settlement of executed securities orders.

          1.2 Activities to be Performed by Financial Institution

     (a) Financial Institution shall assist customers in completing UVEST's
Brokerage Account Application and Customer Agreement when appropriate, and, as

agreements and information as deemed necessary.

     (c) Financial Institution shall cooperate with UVEST in effecting the

recommendations and will not exercise any discretionary or other authority with
respect to the Accounts.

     (d) Each party shall be responsible for compliance with federal and state
laws and regulations applicable to it. Without limiting the generality of the
foregoing, UVEST agrees that it will (i) perform its duties and responsibilities
hereunder diligently and with due care, (ii) provide full and adequate
supervision to all of its brokers and registered representatives and (iii)
notify the Financial Institution, promptly in writing, of any disciplinary
action that may be taken against it by the Securities Exchange Commission

     (e) Each party shall be responsible for the on-going training of personnel
who will assist customers in completing the required forms of UVEST and in the
policies and procedures of UVEST.

     (f) Financial Institution will be responsible for determining that no
customer is a minor when such customer completes the UVEST Broker Account

4. MAINTENANCE OF BOOKS

     UVEST shall carry all Accounts as UVEST accounts in the name of the

any losses, claims, damages, liabilities or expenses (which shall include, but
not be limited to all costs of defense and investigation and all reasonable
attorney's fees) to which Financial Institution may become subject, insofar as
such losses, claims, damages, liabilities or expenses arise out of or are based
upon any of the following:

     (a) negligence or the willful misconduct of UVEST or its employees in
     providing the services contemplated hereunder;

                                       4


     5.3 No liability for indemnification under Sections 5.1 or 5.2 shall arise
unless the party making a claim under this section provides to the party against
whom a claim is being made written notice of the commencement of any action
within 10 days thereof. The failure of a party against whom such claim is made
will not relieve the party against whom such claim is made from any liability
which it may have otherwise than under this Section. If any such action is
brought against any party, and it notifies the other party of the commencement
thereof, the party against whom such claim is made will be entitled to defend or
prosecute such action at its expense and through counsel of its own choosing. No
settlement of any action against the party making a claim under this section
shall be made without the consent of the party against whom such claim is made.
