Dreyfus Service Corporation

Gentlemen:

We wish to enter into an Agreement with you for servicing shareholders of,
and administering shareholder accounts in, certain mutual fund(s) managed,
advised or administered by The Dreyfus Corporation or its subsidiaries or
affiliates (hereinafter referred to individually as the "Fund" and
collectively as the "Funds"). You are the principal underwriter as defined
in the Investment Company Act of 1940, as amended (the "Act"), and the
exclusive agent for the continuous distribution of shares of the Funds.

The terms and conditions of this Agreement are as follows:

1.   We agree to provide shareholder and administrative services for our
     clients who own shares of the Funds ("clients"), which services may
     include, without limitation: answering client inquiries about the
     Funds; assisting clients in changing dividend options, account
     designations and addresses; performing sub-accounting; establishing
     and maintaining shareholder accounts and records; processing purchase
     and redemption transactions; investing client account cash balances
     automatically in shares of one or more of the Funds; providing
     periodic statements and/or reports showing a client's account balance
     and integrating such statements with those of other transactions and
     balances in the client's other accounts serviced by us; arranging for
     bank wires; and providing such other information and services as you
     reasonably may request, to the extent we are permitted by applicable
     statute, rule or regulation. We represent and warrant to, and agree
     with you, that (a) the compensation payable to us hereunder, together
     with any other compensation payable to us by clients in connection
     with the investment of their assets in shares of the Funds, will be
     properly disclosed by us to our clients; and (b) we have taken
     appropriate verification measures to ensure transactions are in
     compliance with all applicable laws and regulations concerning foreign
     exchange controls and money laundering.

2.   We shall provide such office space and equipment, telephone facilities
     and personnel (which may be all or any part of the space, equipment
     and facilities currently used in our business, or all or any personnel
     employed by us) as is necessary or beneficial for providing
     information and services to each Fund's shareholders, and to assist
     you in servicing accounts of clients. We shall transmit promptly to
     clients all communications sent to us for transmittal to clients by or
     on behalf of you, any Fund, or any Fund's investment adviser,
     custodian or transfer or dividend disbursing agent.

3.   We agree that neither we nor any of our employees or agents are
     authorized to make any representation concerning shares of any Fund,
     except those contained in the then current Prospectus for such Fund,
     copies of which will be supplied by you to us in reasonable quantities
     upon request. We shall have no authority to act as agent for the Funds
     or for you.

4.   You reserve the right, at your discretion and without notice, to
     suspend the sale of shares or withdraw the sale of shares of any or
     all of the Funds.

5.   We acknowledge that this Agreement shall become effective for a Fund
     only when approved by vote of a majority of (i) the Fund's Board of
     Directors or Trustees or Managing General Partners, as the case may be
     (collectively "Directors," individually "Director"), and (ii)
     Directors who are not "interested persons" (as defined in the Act) of
     the Fund and have no direct or indirect financial interest in this
     Agreement, cast in person at a meeting called for the purpose of
     voting on such approval.

6.   This Agreement shall continue until the last day of the calendar year
     next following the date of execution, and thereafter shall continue
     automatically for successive annual periods ending on the last day of
     each calendar year. For all Funds as to which Board approval of this
     Agreement is required, such continuance must be approved specifically
     at least annually by a vote of a majority of (i) the Fund's Board of
     Directors and (ii) Directors who are not "interested persons" (as
     defined in the Act) of the Fund and have no direct or indirect
     financial interest in this Agreement, by vote cast in person at a
     meeting called for the purpose of voting on such approval. For any
     Fund as to which Board approval of this Agreement is required, this
     Agreement is terminable without penalty, at any time, by a majority of
     the Fund's Directors who are not "interested persons" (as defined in
     the Act) and have no direct or indirect financial interest in this
     Agreement or, upon not more than 60 days' written notice, by vote of
     holders of a majority of the Fund's shares. As to all Funds, this
     Agreement is terminable without penalty upon 15 days' notice by either
     party. In addition, you may terminate this Agreement as to any or all
     Funds immediately, without penalty, if the present investment adviser
     of such Fund(s) ceases to serve the Fund(s) in such capacity, or if
     you cease to act as distributor of such Fund(s). Notwithstanding
     anything contained herein, if we fail to perform the shareholder
     servicing and administrative functions contemplated herein by you as
     to any or all of the Funds, this Agreement shall be terminable
     effective upon receipt of notice thereof by us. This Agreement also
     shall terminate automatically in the event of its assignment (as
     defined in the Act).

7.   In consideration of the services and facilities described herein, we
     shall be entitled to receive from you, and you agree to pay to us, the
     fees described as payable to us in each Fund's Service Plan adopted
     pursuant to Rule 12b-1 under the Act, and Prospectus and related
     Statement of Additional Information. We understand that any payments
     pursuant to this Agreement shall be paid only so long as this
     Agreement and such Plan are in effect. We agree that no Director,
     officer or shareholder of the Fund shall be liable individually for
     the performance of the obligations hereunder or for any such payments.

8.   We agree to provide to you and each applicable Fund such information
     relating to our services hereunder as may be required to be maintained
     by you and/or such Fund under applicable federal or state laws, and
     the rules, regulations, requirements or conditions of applicable
     regulatory and self-regulatory agencies or authorities.

9.   This Agreement shall not constitute either party the legal
     representative of the other, nor shall either party have the right or
     authority to assume, create or incur any liability or any obligation
     of any kind, express or implied, against or in the name of or on
     behalf of the other party.

10.  All notices required or permitted to be given pursuant to this
     Agreement shall be given in writing and delivered by personal delivery
     or by postage prepaid, registered or certified United States first
     class mail, return receipt requested, or by telecopier, telex,

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing Recitals, the mutual
covenants and agreements contained herein and the acts to be performed
hereunder, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by each of the parties, the parties
hereby agree as follows:

         1. Incorporation of Recitals/Definitions. The foregoing Recitals and
definitions set forth above are incorporated herein and made a part hereof.
Terms which are defined in the Credit Agreement and which are not otherwise
defined in this Amendment shall have the meanings ascribed to them in the Credit
Agreement.

         2. Waiver.

            (a) Acknowledgment of Default. Borrower and Guarantors acknowledge
         that as of the date hereof, Borrower has not obtained a Replacement
         Line Commitment and, as a result, the Revolving Loan Scheduled Maturity
         Date was May 31, 2001, and Borrower's failure to pay the Obligations in
         full on or before May 31, 2001, constitutes an Event of Default and
         other Events of Default (including those identified in Section 2(a) and
         (b) of the Tenth Amendment) exist under the Credit Agreement
         (collectively, the "Existing Defaults").

            (b) Waiver. Banks hereby waive the Existing Defaults, all such
         waivers being effective through November 1, 2001, and, upon receipt by
         Agent, after the effective date of the Eleventh Amendment and on or
         prior to November 1, 2001, of not less than One Million Dollars
         ($1,000,000) (the "Minimum Required Paydown"), such waivers being
         extended and effective through January 31, 2002. Banc One Leasing also
         hereby waives compliance by Borrower with Section 18 of the Master
         Lease. In addition, Banc One Leasing hereby waives any default or event
         of default under the Master Lease or the Leases by reason of the
         Existing Defaults, such waivers effective through November 1, 2001 and,
         upon receipt by the Agent of the Minimum Required Paydown, through
         January 31, 2002.

            (c) Effect of Waiver. The waivers granted pursuant to Subsection (b)
         of this Section 2 are not and shall not be deemed to be a waiver by
         Banks of any other Defaults or Events of Default which may now or
         hereafter exist.

                    payments paid after July 1, 2001, shall be deemed to have
                    been principal payments on the Revolving Loans.

                    (iii) The Borrower shall, upon demand by Agent, pay to the
                    Agent as a principal reduction of the Revolving Loan the
                    amount by which the principal balance then outstanding on
                    the Revolving Loans at any time exceeds the Borrowing Base
                    plus the

                    amount of the consolidated cash of the Borrower and the

                    Required Paydown; and (z) upon a Change in Control, the
                    entire unpaid principal sum of and all accrued interest upon
                    the Loans, as reduced, if at all, by clause (v) of this
                    Section 2.6(d).

                    (v) Notwithstanding any provision of this Agreement or the
                    Notes to the contrary, upon payment by the Borrower to the
                    Agent for the ratable benefit of the Banks, in one or more
                    transactions, on or prior to November 1, 2001, of payments

                    and discharged) and Banks shall deliver to Borrower the

                    Notes to the contrary, if the aggregate sum of all principal
                    payments made by the Borrower, in one or more transactions,
                    to the Agent for the ratable benefit of the Banks on or
                    before November 1, 2001 is less than the amounts set forth

                    Dollars ($2.00) for every One Dollar ($1.00) received). Any
                    principal payments received by the Agent for the ratable
                    benefit of the Banks after January 31, 2002, shall be
                    credited Dollar for Dollar and no forgiveness of
                    indebtedness or additional payment credits shall be granted.
                    The provisions of Section 2.6(d)(v) and this Section
                    2.6(d)(vi) shall not be construed to apply to any of

         this Section 9.11 shall be a principal payment for purposes of Sections

         in full, taking into account the provisions of Section 2.6(d)(v) of
         this Agreement, on or prior to January 31, 2002. In the event that the

         Borrower to deliver the written report of this consultant, properly
         acknowledged as such consultant's work-product.

         projections for Fiscal Year 2001 dated April, 2001 (as previously
         delivered to Banks) and for the period from October 1, 2001, through
         January 31, 2002, Capital Expenditures shall not exceed the sum of
         $200,000.

              9.14 Additional Information. Borrower shall: (i) make

         Obligations and such other matters as Agent may reasonably request;
         (ii) provide periodic status reports received from Borrower's Financial
         Management Consultant and/or Investment Advisor; and (iii) promptly

         Consultant or Investment Advisor in connection with Borrower's efforts
         to achieve a strategic alliance, merger or sale of all or a portion of
         Borrower's businesses, capital stock, other equity securities or
         assets, to the extent that such letter, expression or offer is not
         subject to a confidentiality agreement or non-disclosure provision.

             9.15 Cash Collateral Account. So long as any portion of the
         Revolving Loans remain unpaid, Borrower shall maintain with Agent a
         cash collateral account, over which Agent alone shall have the power of
         withdrawal. So long as no Event of Default shall have occurred, all
         funds deposited in the cash collateral account shall be released to
         Borrower's general operating account promptly after Agent has received
         irrevocable credit with respect thereto.

             9.16 Proceeds of Commonwealth Edison Receivable. Borrower
         claims to be owed in excess of Two Million Seven Hundred Thousand
         Dollars ($2,700,000) by Commonwealth Edison (the "Com Ed Claim"), which
         is disputed by Commonwealth Edison. In the event of any payment of the
         Com Ed Claim prior to payment in full of the Revolving Loans, Borrower
         shall pay to Agent for application against the Revolving Loans and as a
         permanent reduction of the Revolving Loans Commitment fifty percent
         (50%) of the amount of such payment (net of legal fees and litigation
         costs related to collection thereof) after the sum of all payments
         received exceeds One Million Dollars ($1,000,000). Any payment made
         pursuant to this Section 9.16 shall be counted toward the Minimum
         Required Paydown, if not otherwise fully paid, and shall be a principal
         payment for purposes of Section 2.6(d)(v) and 2.6(d)(vi).

             9.17 Additional Events of Default. In addition to the Events
         of Default set forth in Section 6.1 hereof and notwithstanding any
         provision of this Agreement to the contrary, each of the following
         events shall constitute an Event of Default hereunder:

<PAGE>   15

      Borrower fails to timely deliver: (i) any contracts required by Section
      9.10; (ii) a Rolling Cash Flow Projection; (iii) any Borrowing Base
      Certificate, A/R Aging, Revenue Report or Status Report; or (iv) any other
      information required to be delivered to Agent or Banks pursuant to the
      terms of this Agreement.

               (b) Failure to Pay Monthly Renewal Fee. Borrower fails to timely
      pay any Monthly Renewal Fee.

               (c) Total Amount of Loans. The aggregate principal balance of the
      Loans at any one time outstanding exceeds the sum of: (i) the Borrowing
      Base; plus (ii) Borrower's consolidated unbilled revenues as at the end of
      the fiscal month most recently closed; plus (iii) Borrower's consolidated
      cash.

               (d) Cash Receipts Shortfall. Borrower's actual cumulative
      consolidated cash receipts for period beginning June, 2001, and measured
      at the close of each fiscal month, beginning July 30, 2001, are less than
      eighty-five percent (85.0%) of the amount of the anticipated cumulative
      consolidated cash receipts at such month-end, as set forth in Borrower's
      projections dated June 22, 2001 (the "June 2001 Projections").

               (e) Cash Expenditures. Borrower's actual cumulative cash
      expenditures for months ending June 30, 2000 and thereafter (excluding
      payments to the Agent and/or the Banks for application against the
      Obligations or the Master Lease) exceed Borrower's projected cash
      receipts, on a cumulative basis for the same period.

shall be amended as follows: (i) the Interest Bearing Term Note in favor of each
of the Banks is hereby amended by deleting the phrase in the upper right-hand
