("Holdings") intends to make a tender offer (the "Tender Offer") for all the outstanding common stock of Data Research Associates, Inc. ("DRA") for $11.00 per share in cash, resulting in a total purchase price of approximately $49.7 million. Following completion of the Tender Offer, McGuire Acquisition Inc. will be merged into DRA (the "Merger", and together with the Tender Offer, the "Acquisition"), at which time any shares of DRA not tendered will be converted into the right to receive in cash the Tender Offer price. All terms and conditions of the Tender Offer and Merger, and the structure thereof, will be consistent with the provisions of the Agreement and Plan of Merger, dated as of May 16, 2001 (the "Merger Agreement"), among DRA, McGuire Acquisition Inc. and Holdings, as in effect on the date hereof, and otherwise shall be satisfactory to BNP Paribas. BNP Paribas understands that all funding required to effect the Acquisition, to pay fees and expenses in connection therewith (which fees and expenses shall not exceed $4.0 million) and to refinance (the "Refinancing") the current senior debt (not more than approximately $11.25 million of which shall be funded, less any amounts amortized prior to the Closing Date (as defined below)) of Sirsi Corporation ("Sirsi") will be provided solely through (i) the incurrence by Sirsi of $45.0 million of senior secured facilities (the "Senior Secured Facilities") more fully described in the term sheet attached hereto as Exhibit A (the "Term Sheet"), (ii) the use of cash on hand of Sirsi and DRA (which cash will be loaned, to the extent needed, to Holdings pursuant to a subordinated credit facility (the "DRA Facility") acceptable to BNP Paribas), (iii) at least $2.2 million of additional proceeds of new common equity contributions from existing equity holders of Holdings (the "Additional Equity Investment") and (iv) the proceeds of at least $1.0 million of additional subordinated loans to Holdings in the form of an increase in the existing Holdings seller note (the "Additional Seller Note Financing" and, together with the Senior Secured Facilities, the DRA Facility and the Additional Equity Investment, the "Financing Transactions", and the Financing Transactions, together with the Acquisition and the Refinancing, the "Transaction"); PROVIDED that the amount of the Additional Seller Note Financing required to be issued shall be reduced, and to the extent such permitted reduction would otherwise exceed $1.0 million, the amount of the 1 Additional Equity Investment shall be reduced to the extent of such excess, by an amount equal to the amount by which the aggregate proceeds of the Financing Transactions available to pay amounts owing in connection with the Transaction and to pay fees and expenses incurred or expected to be incurred in connection therewith (including for this purpose the full amount of the Additional Equity Investment and the Additional Seller Note Financing, but including only that portion of the Senior Secured Facilities otherwise available for such purpose to the extent Holdings' pro-forma (after giving effect to the Transaction and assuming that 100% of the common equity of DRA had been acquired) consolidated leverage ratio (calculated on a latest twelve month basis without giving effect to Holdings' existing seller notes, the Additional Seller Note Financing or the DRA Facility and otherwise in a manner acceptable to BNP Paribas) would not exceed 3.30:1.00 on the Closing Date (as defined below)) exceed the aggregate amount required to fund the Transaction and to pay such fees and expenses.

To assist BNP Paribas in its syndication efforts, you hereby agree (a) to provide and cause your advisors to provide BNP Paribas and the other syndicate members upon request with all reasonable information deemed necessary by us to complete syndication, including but not limited to information and evaluations prepared by Holdings, Sirsi, McGuire Acquisition Inc., DRA, or any of your or their respective advisors, relating to the Transaction and the other transactions contemplated hereby, (b) to assist BNP Paribas upon request in the preparation of an Information Memorandum to be used in connection with the syndication of the Senior Secured Facilities and (c) to make available the senior officers and representatives of Holdings, Sirsi, McGuire Acquisition, Inc. and (to the extent practicable) DRA, in each case from time to time and to attend and make presentations regarding the business and prospects of Sirsi and DRA and their respective subsidiaries at a meeting or meetings of Lenders or prospective Lenders.
