may subcontract any of such services to one or more firms designated by PSC,
provided that PSC (i) shall be solely responsible for all compensation payable
to any such firm and (ii) shall be liable to Customer for the acts or omissions
of any such firm to the same extent as PSC would be liable to Customer with
respect to any such act or omission hereunder.

as are prescribed for each service in the Exhibits attached hereto. Customer
agrees to examine or to ask any other authorized recipient to examine each such
report or copy promptly and will report or cause to be reported any errors or
discrepancies therein of which Customer then has any knowledge. PSC may at its
option at any time, and shall forthwith upon Customer's demand, turn over to
Customer and cease to retain in PSC's files, any and all records and documents
created and maintained by PSC pursuant to this Agreement which are no longer
needed by PSC in the performance of its services or for its protection.

         If not so turned over to Customer, such documents and reports will be
retained by PSC for six years from the year of creation, during the first two of
which the same shall be in readily accessible form. At the end of six years,
such records and documents will be turned over to Customer by PSC unless
Customer authorizes their destruction.

consistent with industry standards in order to safeguard Customer's checks,
records and other data from loss or damage attributable to fire or theft. PSC

checks, records and other data in the event of such loss and shall notify
Customer in the event of a material adverse change in such insurance coverage.

event of damage or loss occurring to Customer's records or data such that PSC is
unable to meet the terms of this Agreement, PSC shall transfer all records and
data to a transfer agent of Customer's choosing upon Customer's written
authorization to do so.

liable or responsible for delays or errors occurring by reason of circumstances
beyond its control including acts of civil, military or banking authority,
national emergencies, labor difficulties, fire, flood or other catastrophes,
acts of God, insurrection, war, riots, failure of transportation, communication
or power supply.

         6. CONFIDENTIALITY. PSC will keep confidential all records and
information provided by Customer or by the shareholders of the Account to PSC,
except to the extent disclosures are required by this Agreement, are required by

jurisdiction or by a state or federal agency or governmental authority.

         7. CUSTOMER INSPECTION. Upon reasonable notice, in writing signed by

         8. RELIANCE BY PSC ON INSTRUCTIONS AND ADVICE; INDEMNITY. PSC shall be
entitled to seek advice of Customer's legal counsel with respect to PSC's
responsibilities and duties hereunder and shall in no event be liable to
Customer for any action taken pursuant to such advice, except to the extent that
Customer's legal counsel determines in its sole discretion that the rendering of
advice to PSC would result in a conflict of interest.

         Whenever PSC is authorized to take action hereunder pursuant to proper
instructions from Customer, PSC shall be entitled to rely upon any certificate,
letter or other instrument or telephone call reasonably believed by PSC to be
genuine and to have been properly made or signed by an officer or other
authorized agent of Customer, and shall be entitled to receive as conclusive
proof of any fact or matter required to be ascertained by it hereunder a
certificate signed by an officer of Customer or any other person authorized by
Customer's Board of Trustees.

         Subject to the provisions of Section 13 of this Agreement, Customer
agrees to indemnify and hold PSC, its employees, agents and nominees harmless
from any and all claims, demands, actions and suits, whether groundless or
otherwise, and from and against any and all judgments, liabilities, losses,
damages, costs, charges, counsel fees and other expenses of every nature and
character arising out of or in any way relating to PSC's action or non-action

respect to the Account.

         Notwithstanding the above, whenever Customer may be asked to indemnify
or hold PSC harmless, Customer shall be advised of all pertinent facts arising
from the situation in question. Additionally, PSC will use reasonable care to
identify and notify Customer promptly concerning


                                       -2-





any situation, which presents, actually or potentially, a claim for
indemnification against Customer. Customer shall have the option to defend PSC
against any claim for which PSC is entitled to indemnification from Customer
under the terms hereof, and in the event Customer so elects, it will notify PSC
and, thereupon, Customer shall take over complete defense of the claim and PSC
shall sustain no further legal or other expenses in such a situation for which
indemnification shall be sought or entitled. PSC may in no event confess any
claim or make any compromise in any case in which Customer will be asked to
indemnify PSC except with Customer's prior written consent.

         9. MAINTENANCE OF DEPOSIT ACCOUNTS. PSC shall maintain on behalf of
Customer such deposit accounts as are necessary or desirable from time to time
