SECTION 2. TRUST.

                  (a) Establishment. The Sponsor hereby establishes the Trust,
with the Trustee. The Trust hereby established shall be irrevocable. The Trust
shall consist of an initial contribution of money or other property acceptable
to the Trustee in its sole discretion, made by the Sponsor or transferred from a
previous trustee under the Plan, such additional sums of money as shall from
time to time be delivered to the Trustee under the Plan, all investments made
therewith and proceeds thereof, and all earnings and profits thereon, less the
payments that are made by the Trustee as provided herein, without distinction
between principal and income. The Trustee hereby accepts the Trust on the terms
and conditions set forth in this Agreement. In accepting this Trust, the Trustee
shall be accountable for the assets received by it, subject to the terms and
conditions of this Agreement.

                  (b) Grantor Trust. The Trust is intended to be a grantor
trust, of which the Sponsor is the grantor, within the meaning of subpart E,
part I, subchapter J, chapter 1, subtitle A of the Internal Revenue Code of
1986, as amended, and shall be construed accordingly.

                  (c) Trust Assets. The principal of the Trust, and any earnings
thereon shall be held separate and apart from other funds of the Sponsor and
shall be used exclusively for the uses and purposes of Participants and general
creditors as herein set forth. Participants and their beneficiaries shall have
no preferred claim on, or any beneficial ownership interest in, any assets of
the Trust. Any rights created under the Plan and this Agreement shall be mere
unsecured contractual rights of Participants and their beneficiaries against the
Sponsor. Any assets held by the Trust will be subject to the claims of the
Sponsor's general creditors under federal and state law in the event of
Insolvency, as defined in Section 13(a).

                  (d) Non-Assignment. Benefit payments to Participants and their
beneficiaries funded under this Trust may not be anticipated, assigned (either
at law or in equity), alienated, pledged, encumbered, or subjected to
attachment, garnishment, levy, execution, or other legal or equitable process.

                  (e) Change in Control. Upon a Change in Control, the Sponsor
shall, as soon as possible, but in no event longer than thirty (30) days
following the Change in Control, as defined herein, make an irrevocable
contribution to the Trust in an amount that is sufficient to pay each
Participant the benefits to which Participants would be entitled pursuant to the
terms of the Plan as of the date on which the Change in

                                       3
<PAGE>

Control occurred. The Sponsor shall also provide additional funding in such
amounts as are reasonably estimated to cover any expenses of the Trust for five
(5) years after such Change in Control.

SECTION 3. PAYMENTS TO SPONSOR. Except as provided under Section 13, the Sponsor
shall have no right to retain or divert to others any of the Trust assets before
all payment of benefits have been made to the Participants and their
beneficiaries pursuant to the terms of the Plan.

SECTION 4. DISBURSEMENTS.

                  (a) Directions from Administrator. The Trustee shall disburse
monies to the Sponsor for benefit payments in the amounts that the Administrator
directs from time to time in writing. The Trustee shall have no responsibility
to ascertain whether the Administrator's direction complies with the terms of
the Plan or any applicable law. Notwithstanding any other agreements between the
Sponsor and any affiliates of the Trustee as documented in the Plan
Administration Manual, the Trustee shall not be responsible for: (i) making
benefit payments to Participants under the Plan, (ii) any Federal, State or
local income tax reporting or withholding with respect to such Plan benefits,
and (iii) FICA (Social Security and Medicare) or any Federal or State
unemployment tax with respect to Plan distributions.

                  (b) Limitations. The Trustee shall not be required to make any
disbursement in excess of the net realizable value of the assets of the Trust at
the time of the disbursement. The Trustee shall not be required to make any
disbursement in cash unless the Administrator has provided a written direction
as to the assets to be converted to cash for the purpose of making the
disbursement.

SECTION 5. INVESTMENT OF TRUST.

                  (a) Selection of Investment Options. The Trustee shall have no
responsibility for the selection of investment options under the Trust and shall
not render investment advice to any person in connection with the selection of
such options.

                  (b) Available Investment Options. The Sponsor shall direct the
Trustee as to what investment options the Trust shall be invested in (i) during
the Participant Recordkeeping Reconciliation Period, and (ii) following the
Participant Recordkeeping Reconciliation Period, subject to the following
limitations. The Sponsor may determine to offer as investment options to
Participants only (i) Mutual Funds and (ii) Benchmark Funds identified on
Schedule "A" attached hereto; provided, however, that the Trustee shall not be
considered a fiduciary with investment discretion. The Trust shall be invested
in Mutual Funds or other registered securities as directed by the Sponsor,
however, the Trustee shall not be considered a fiduciary with investment
discretion. The Sponsor may add or remove investment options with

                                       4
<PAGE>

the consent of the Trustee and upon mutual amendment of this Agreement and the
Schedules thereto to reflect such additions.

                  (c) Investment Directions. In order to provide for an
accumulation of assets comparable to the contractual liabilities accruing under
the Plan, the Sponsor may direct the Trustee in writing to invest the assets
held in the Trust to correspond to the hypothetical investments made for
Participants under the Plan. Such directions may be made by Participants by use
of a Participant service representative, the Voice Response System ("VRS"), the
internet or such other electronic means as may be agreed upon from time to time
by the Sponsor and the Trustee, maintained for such purposes by the Trustee or
its agents, in accordance with Schedule "E." In the event that the Trustee fails
to receive a proper direction from the Sponsor or from Participants regarding
investments for Participant deferrals, the deferrals shall be invested in the
Moody's Baa Index until the Trustee receives a proper direction. However for
assets in the TIP Restoration source, in the event that the Trustee fails to
receive a proper direction from the Sponsor or from Participants, regarding
investments for Participant deferrals, the deferrals shall be invested in the
Fidelity Money Market Trust: Retirement Money Market Portfolio until the Trustee
receives a proper direction. All assets received into the Trust for which no
direction has been received by the Trustee shall be invested in Fidelity
Institutional Money Market: Portfolio Class I.

                  The Sponsor's designation of available investment options
under paragraphs (a) and (b) above, the maintenance of accounts for each
Participant and the crediting of investments to such accounts, the giving of
investment directions by Participants under this paragraph (c), and the exercise
by Participants of any other powers relating to investments under this Section 5
are solely for the purpose of providing a mechanism for measuring the obligation
of the Sponsor to any particular Participant under the applicable Plan. As
provided in Section 2(c) above, no Participant or beneficiary will have any
preferential claim to or beneficial ownership interest in any asset or
investment, and the rights of any Participant and his or her beneficiaries under
the applicable Plan and this Agreement are solely those of an unsecured general
creditor of the Sponsor with respect to the benefits of the Participant under
the Plan.

                  (d) Mutual Funds. On the effective date of this Agreement, in
lieu of receiving a printed copy of the prospectus for each Fidelity Mutual Fund
selected by the Sponsor as a Plan investment option or short-term investment
fund, the Sponsor hereby consents to receiving such documents electronically.
The Sponsor shall access each prospectus on the internet after receiving notice
from the Trustee that a current version is available online at a website
maintained by the Trustee or its affiliate. Trustee represents that on the
effective date of this Agreement, a current version of each such prospectus is
available at https://www.fidelity.com or such successor website as Trustee may
notify the Sponsor of in writing from time to time. Named Fiduciary represents
that it has accessed/will access each such prospectus at

                                       5
<PAGE>

https://www.fidelity.com or such successor website as Trustee may notify the
Sponsor of in writing from time to time as of the effective date of this
Agreement. Trust investments in Mutual Funds shall be subject to the following
limitations:

                           (i) Execution of Purchases and Sales. Purchases and
sales of Fidelity Mutual Funds (other than for Exchanges) for both Participant
activity and those necessary for assetizing the Trust shall be made on the date
on which the Trustee receives from the Sponsor in good order all information and
documentation necessary to accurately effect such purchases and sales (or in the
case of a purchase, the subsequent date on which the Trustee has received a wire
transfer of funds necessary to make such purchase). Transactions involving
Mutual Funds not advised by Fidelity Management & Research Company shall be
executed in accordance with the operating procedures set forth in Schedule "D"
attached hereto. Exchanges of Mutual Funds shall be done in accordance with
Schedule "E" attached hereto.

                           (ii) Voting. 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 the Sponsor
for the shares of the Mutual Fund held in the Trust together with a voting
direction form for return to the Trustee or its designee. The Sponsor shall have
the right to direct the Trustee as to the manner in which the Trustee is to vote
the shares held in the Trust. The Trustee shall vote the shares held in the
Trust in the same manner as directed by the Sponsor under the Plan. The Trustee
shall not vote shares for which it has received no corresponding directions from
the Sponsor. With respect to all rights other than the right to vote, the
Trustee shall follow the directions of the Sponsor. The Trustee shall have no
duty to solicit directions from the Sponsor.

                  (e) Trustee Powers. The Trustee shall have the following
powers and authority:

                           (i) Subject to paragraphs (b), (c) and (d) of this
Section 5, to sell, exchange, convey, transfer, or otherwise dispose of any
property held in the Trust, by private contract or at public auction. No person
dealing with the Trustee shall be bound to see to the application of the
purchase money or other property delivered to the Trustee or to inquire into the
validity, expediency, or propriety of any such sale or other disposition.

                           (ii) To cause any securities or other property held
as part of the Trust to be registered in the Trustee's own name, in the name of
one or more of its nominees, or in the Trustee's account with the Depository
Trust Company of New York and to hold any investments in bearer form, but the
books and records of the Trustee shall at all times show that all such
investments are part of the Trust.

                                       6
<PAGE>

                           (iii) To keep that portion of the Trust in cash or
cash balances as the Sponsor or Administrator may, from time to time, deem to be
in the best interest of the Trust.

                           (iv) To make, execute, acknowledge, and deliver any
and all documents of transfer or conveyance and to carry out the powers herein
granted.

                           (v) With the prior consent of the Sponsor, to settle,
compromise, or submit to arbitration any claims, debts, or damages due to or
arising from the Trust; to commence or defend suits or legal or administrative
proceedings; to represent the Trust in all suits and legal and administrative
hearings; and to pay all reasonable expenses arising from any such action, from
the Trust if not paid by the Sponsor.

                           (vi) With the prior consent of the Sponsor, to employ
legal, accounting, clerical, and other assistance as may be required in carrying
out the provisions of this Agreement and to pay their reasonable expenses and
compensation from the Trust if not paid by the Sponsor.

                           (vii) With notice to the Sponsor, to do all other
acts although not specifically mentioned herein, as the Trustee may deem
necessary to carry out any of the foregoing powers and the purposes of the
Trust.

                  Trustee will file an annual fiduciary return to the extent
required by law.

SECTION 6. RECORDKEEPING AND ADMINISTRATIVE SERVICES TO BE PERFORMED.

                  (a) General. The Trustee shall perform those recordkeeping and
administrative functions described in Schedule "A" attached hereto. These
recordkeeping and administrative functions shall be performed within the
framework of the Administrator's written directions regarding the Plan's
provisions, guidelines and interpretations.

                  (b) Accounts. The Trustee shall keep accurate accounts of all
investments, receipts, disbursements, and other transactions hereunder, and
shall report the value of the assets held in the Trust as of the last day of
each fiscal quarter of the Plan and, if not on the last day of a fiscal quarter,
the date on which the Trustee resigns or is removed as provided in Section 9 of
this Agreement or is terminated as provided in Section 11. Within three (3)
Business Days following each Reporting Date the Trustee shall file with the
Administrator a written account setting forth all investments, receipts,
disbursements, and other transactions effected by the Trustee between the
Reporting Date and the prior Reporting Date, and setting forth the value of the
Trust as of the Reporting Date. Except as otherwise required under applicable
law, upon the expiration of six (6) months from the date of filing such account
with the Administrator, the

                                       7
<PAGE>

Trustee shall have no liability or further accountability to anyone with respect
to the propriety of its acts or transactions shown in such account, except with
respect to such acts or transactions as to which the Sponsor shall within such
six (6) month period file with the Trustee written objections.

                  (c) Inspection and Audit. All records generated by the Trustee
in accordance with paragraphs (a) and (b) shall be open to inspection and audit,
during the Trustee's regular business hours prior to the termination of this
Agreement, by the Administrator or any person designated by the Administrator.
Upon the resignation or removal of the Trustee or the termination of this
Agreement, the Trustee shall provide to the Administrator, at no expense to the
Sponsor, in the format regularly provided to the Administrator, a statement of
each Participant's accounts as of the resignation, removal, or termination, and
the Trustee shall provide to the Administrator or the Plan's new recordkeeper
such further records as are reasonable, at the Sponsor's expense.

                  (d) Effect of Plan Amendment. The Trustee's 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 of any amendment to
the Plan as soon as administratively feasible following the amendment's
adoption, and on the Administrator providing the Trustee on a timely basis with
all the information the Administrator deems necessary for the Trustee to perform
the recordkeeping and administrative services and such other information as the
Trustee may reasonably request.

                  (a) Identity of Administrator. The Trustee shall be fully
protected in relying on the fact that the Administrator under the Plan is the
individual or persons named as such above or such other individuals or persons
as the Sponsor may notify the Trustee in writing.

                  (b) Directions from Administrator. Whenever the Administrator
provides a direction to the Trustee, the Trustee shall not be liable for any
loss, or by reason of any breach, arising from the direction if the direction is
contained in a writing (or is oral and immediately confirmed in a writing)
signed by any individual whose name and signature have been submitted (and not
withdrawn) in writing to the Trustee by the Administrator in the form attached
hereto as Schedule "C", provided the Trustee reasonably believes the signature
of the individual to be genuine. Such direction may be made via electronic data
transfer ("EDT") in accordance with procedures agreed to by the Administrator
and the Trustee; provided, however, that the Trustee shall be fully protected in
relying on such direction as if it were a direction made in writing by the
Administrator. The Trustee shall have no responsibility to ascertain any
direction's (i) accuracy, (ii) compliance with the terms of the Plan or any
applicable law, or (iii) effect for tax purposes or otherwise.

                  (c) Directions from Participants. The Trustee shall not be
liable for any loss which arises from any Participant's exercise or non-exercise
of rights under Section 5 over the assets in the Participant's accounts.

                  (d) Indemnification. The Sponsor shall indemnify the Trustee
against, and hold the Trustee harmless from, any and all loss, damage, penalty,
liability, cost, and expense, including without limitation, reasonable
attorneys' fees and disbursements, that may be incurred by, imposed upon, or
asserted against the Trustee by reason of any claim, regulatory proceeding, or
litigation arising from any act done or omitted to be done by any individual or
person with respect to the Plan or Trust, excepting only any and all loss, etc.,
arising solely from the Trustee's negligence or bad faith.

         The Trustee shall indemnify the Sponsor against, and hold the Sponsor
harmless from, any and all loss, damage, penalty, liability, cost and expense,
including without limitation, reasonable attorneys' fees and disbursements, that
may be incurred by, imposed upon, or asserted against the Sponsor by reason of
any claim, regulatory proceeding, or litigation arising from Trustee's
negligence or bad faith.

                  (c) Notice Period. In the event either party desires to
terminate this Agreement or any Services hereunder, the party shall provide at
least sixty (60) days prior written notice of the termination date to the other
party; provided, however, that the receiving party may agree, in writing, to a
shorter notice period.

                  (d) Transition Assistance. In the event of termination of this
Agreement, if requested by Sponsor, Fidelity shall assist Sponsor in developing
a plan for the orderly transition of the Plan data, cash and assets then
constituting the Trust and services provided by Fidelity hereunder to Sponsor or
its designee. Fidelity shall provide such assistance for a period not extending
beyond sixty (60) days from the termination date of this Agreement. Fidelity
shall provide to Sponsor, or to any person designated by Sponsor, at a mutually
agreeable time, one file of the Plan data prepared and maintained by Fidelity in
the ordinary course of business, in Fidelity's format. Fidelity may provide
other or additional transition assistance as mutually determined for additional
fees, which shall be due and payable by the Sponsor prior to any termination of

reimbursed by the Sponsor for all costs and expenses of the action or proceeding
including, without limitation, reasonable attorneys' fees and disbursements.

SECTION 10. SUCCESSOR TRUSTEE.

                  (a) Appointment. If the office of Trustee becomes vacant for

Trustee under this

                                       10
<PAGE>

Agreement. The successor trustee and predecessor trustee shall not be liable for
the acts or omissions of the other with respect to the Trust.

                  (b) Acceptance. When the successor trustee accepts its
appointment under this Agreement, title to and possession of the Trust assets
shall immediately vest in the successor trustee without any further action on
the part of the predecessor trustee. The predecessor trustee shall execute all
instruments and do all acts that reasonably may be necessary or reasonably may
be requested in writing by the Sponsor or the successor trustee to vest title to
all Trust assets in the successor trustee or to deliver all Trust assets to the
successor trustee.

                  (c) Corporate Action. Any successor of the Trustee or
successor trustee, through sale or transfer of the business or trust department
of the Trustee or successor trustee, or through reorganization, consolidation,
or merger, or any similar transaction, shall, upon consummation of the
transaction, become the successor trustee under this Agreement.

resignation, removal, or termination under this Agreement must be in writing and

SECTION 12. DURATION. This Trust shall continue in effect without limit as to
time, subject, however, to the provisions of this Agreement relating to
amendment, modification, and termination thereof.

SECTION 13. INSOLVENCY OF SPONSOR.

                  (a) Trustee shall cease disbursement of funds for payment of
benefits to Participants and their beneficiaries if the Sponsor is Insolvent.
Sponsor shall be considered "Insolvent" for purposes of this Trust Agreement if
(i) Sponsor is unable to pay its debts as they become due, or (ii) Sponsor is
subject to a pending proceeding as a debtor under the United States Bankruptcy
Code.

                  (b) All times during the continuance of this Trust, the
principal and income of the Trust shall be subject to claims of general
creditors of the Sponsor under federal and state law as set forth below.

                           (i) The Board of Directors and the Chief Executive
Officer of the Sponsor shall have the duty to inform Trustee in writing of
Sponsor's Insolvency. If a person claiming to be a creditor of the

                                       11
<PAGE>

Sponsor alleges in writing to Trustee that Sponsor has become Insolvent, Trustee
shall determine whether Sponsor is Insolvent and, pending such determination,
Trustee shall discontinue disbursements for payment of benefits to Participants
or their beneficiaries.

                           (ii) Unless Trustee has actual knowledge of Sponsor's
Insolvency, or has received notice from Sponsor or a person claiming to be a
creditor alleging that Sponsor is Insolvent, Trustee shall have no duty to
inquire whether Sponsor is Insolvent. Trustee may in all events rely on such
evidence concerning Sponsor's solvency as may be furnished to Trustee and that
provides Trustee with a reasonable basis for making a determination concerning
Sponsor's solvency.

                           (iii) If at any time Trustee has determined that
Sponsor is Insolvent, Trustee shall discontinue disbursements for payments to
Participants or their beneficiaries and shall hold the assets of the Trust for
the benefit of Sponsor's general creditors. Nothing in this Agreement shall in
any way diminish any rights of Plan Participants or their beneficiaries to
pursue their rights as general creditors of Sponsor with respect to benefits due
under the Plan or otherwise.

                           (iv) Trustee shall resume disbursement for the
payment of benefits to Participants or their beneficiaries in accordance with
Section 4 of this Agreement only after Trustee has determined that Sponsor is
not Insolvent (or is no longer Insolvent).

                  (c) Provided that there are sufficient assets, if Trustee
discontinues the payment of benefits from the Trust pursuant to (a) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to
Participants or their beneficiaries under the terms of the Plan for the period
of such discontinuance, less the aggregate amount of any payments made to
Participants or their beneficiaries by Sponsor in lieu of the payments provided
for hereunder during any such period of discontinuance.

SECTION 14. AMENDMENT OR MODIFICATION. This Agreement may be amended or modified
at any time and from time to time only by an instrument executed by both the

Electronic Products only in the course of reasonable administration of or
participation in the Plan and to keep confidential and not publish, copy,
broadcast, retransmit, reproduce, commercially exploit or otherwise

                                       12

thereof without the Trustee's written consent, except, in cases where Trustee
has specifically notified the Sponsor that the Electronic Products or Services
are suitable for delivery to Sponsor's Participants, for non-commercial personal
use by Participants or beneficiaries with respect to their participation in the
plan or for their other retirement planning purposes.

                  (b) The Sponsor shall be responsible for installing and
maintaining all Electronic Products, (including any programming required to
accomplish the installation) and for displaying any and all content associated
with Electronic Services on its computer network and/or Intranet so that such
content will appear exactly as it appears when delivered to Sponsor. All
Electronic Products and Services shall be clearly identified as originating from
the Trustee or its affiliate. The Sponsor shall promptly remove Electronic
Products or Services from its computer network and/or Intranet, or replace the
Electronic Products or Services with updated products or services provided by
the Trustee, upon written notification (including written notification via
facsimile) by the Trustee.

                  (c) All Electronic Products shall be provided to the Sponsor
without any express or implied legal warranties or acceptance of legal liability
by the Trustee, and all Electronic Services shall be provided to the Sponsor
without acceptance of legal liability related to or arising out of the
electronic nature of the delivery or provision of such Services. Except as
otherwise stated in this Agreement, no rights are conveyed to any property,
intellectual or tangible, associated with the contents of the Electronic
Products or Services and related material. The Trustee hereby grants to the
Sponsor a non-exclusive, non-transferable revocable right and license to use the
Electronic Products and Services in accordance with the terms and conditions of
this Agreement.

                  (d) To the extent that any Electronic Products or Services
utilize Internet services to transport data or communications, the Trustee will
take, and Sponsor agrees to follow, reasonable security precautions, however,
except as provided in Section 8(d), the Trustee disclaims any liability for
interception of any such data or communications. The Trustee reserves the right
not to accept data or communications transmitted via electronic media by the
Sponsor or a third party if it determines that the media does not provide
adequate data security, or if it is not administratively feasible for the
Trustee to use the data security provided. The Trustee shall not be responsible
for, and makes no warranties regarding access, speed or availability of Internet
or network services, or any other service required for electronic communication.
The Trustee shall not be responsible for any loss or damage related to or
resulting from any changes or modifications to the Electronic Products or
Services after delivering it to the Sponsor.

outstanding immediately after such merger or consolidation or (B) as merger or

              OPERATIONAL GUIDELINES FOR NON-FIDELITY MUTUAL FUNDS

Pricing

By 7:00 p.m. Eastern Time ("ET") each Business Day, the Non-Fidelity Mutual Fund
Vendor ("Fund Vendor") will input the following information ("Price
Information") into the Fidelity Participant Recordkeeping System ("FPRS") via
the remote access price screen that Fidelity Investments Institutional
Operations Company, Inc. ("FIIOC"), an affiliate of the Trustee, has provided to
the Fund Vendor: (1) the net asset value for each Fund at the Close of Trading,
(2) the change in each Fund's net asset value from the Close of Trading on the
prior Business Day, and (3) in the case of an income fund or funds, the daily
accrual for interest rate factor ("mil rate"). FIIOC must receive Price
Information each Business Day (a "Business Day" is any day the New York Stock
Exchange is open). If on any Business Day the Fund Vendor does not provide such
Price Information to FIIOC, FIIOC shall pend all associated transaction activity
in the Fidelity Participant Recordkeeping System ("FPRS") until the relevant
Price Information is made available by Fund Vendor.

Trade Activity and Wire Transfers

By 7:00 a.m. ET each Business Day following Trade Date ("Trade Date Plus One"),
FIIOC will provide, via facsimile, to the Fund Vendor a consolidated report of
net purchase or net redemption activity that occurred in each of the Funds up to
4:00 p.m. ET on the prior Business Day. The report will reflect the dollar
amount of assets and shares to be invested or withdrawn for each Fund. FIIOC
will transmit this report to the Fund Vendor each Business Day, regardless of
processing activity. In the event that data contained in the 7:00 a.m. ET
facsimile transmission represents estimated trade activity, FIIOC shall provide
a final facsimile to the Fund Vendor by no later than 9:00 a.m. ET. Any
resulting adjustments shall be processed by the Fund Vendor at the net asset
value for the prior Business Day.

The Fund Vendor shall send via regular mail to FIIOC transaction confirms for
all daily activity in each of the Funds. The Fund Vendor shall also send via
regular mail to FIIOC, but no later than the fifth Business Day following
calendar month close, a monthly statement for each Fund. FIIOC agrees to notify
the Fund Vendor of any balance discrepancies within twenty (20) Business Days of
receipt of the monthly statement.

For purposes of wire transfers, FIIOC shall transmit a daily wire for aggregate
purchase activity and the Fund Vendor shall transmit a daily wire for aggregate
redemption activity, in each case including all activity across all Funds
occurring on the same day.

Prospectus Delivery

FIIOC shall be responsible for the timely delivery of Fund prospectuses and
periodic Fund reports ("Required Materials") to Participants, and shall retain
the services of a third-party vendor to handle such mailings. The Fund Vendor
shall be responsible for all materials and production costs, and hereby agrees
to provide the Required Materials to the third-party vendor selected by FIIOC.
The Fund Vendor shall bear the costs of mailing annual Fund reports to
Participants. FIIOC shall bear the costs of mailing prospectuses to
Participants.

Proxies

The Fund Vendor shall be responsible for all costs associated with the
production of proxy materials. FIIOC shall retain the services of a third-party
vendor to handle proxy solicitation mailings and vote tabulation. Expenses
associated with such services shall be billed directly the Fund Vendor by the
third-party vendor.

Participant Communications

                                       21
<PAGE>

The Fund Vendor shall provide internally prepared fund descriptive information
approved by the Funds' legal counsel for use by FIIOC in its written Participant
communication materials. FIIOC shall utilize historical performance data
obtained from third-party vendors (currently Morningstar, Inc., FACTSET Research
Systems and Lipper Analytical Services) in telephone conversations with plan
Participants and in quarterly Participant statements. The Sponsor hereby
consents to FIIOC's use of such materials and acknowledges that FIIOC is not
responsible for the accuracy of third-party information. FIIOC shall seek the
approval of the Fund Vendor prior to retaining any other third-party vendor to
render such data or materials under this Agreement.

Compensation

FIIOC shall be entitled to fees as set forth in a separate agreement with the
Fund Vendor.
