("ISI") and Sandy Spring National Bank (the "Bank") on March 30, 2000 (the "Agreement"), to a tender offer, which ISI will undertake in order to acquire control of CSI Computer Specialists, Inc. ("CSI") Plans of ISI: ISI hereby advises the Bank that it anticipates commencing a tender offer for all of the outstanding common stock of CSI not already owned by Mr. Donald C. Weymer, ISI's founder, Chief Executive Officer, Director and 98% shareholder, in April 2000 (the "Offer"). The Offer is intended to enable ISI to acquire control of, and the entire equity interest in CSI. Upon completion of the Offer, ISI intends to operate CSI as a majority-owned subsidiary of ISI. If the CSI stockholders do not tender all of their common stock, ISI intends to evaluate whether, under the circumstances at that time, it would be in the best interest of ISI and CSI to acquire additional common stock by means of a second tender offer, merger or other transaction. ISI expects to use a portion of the funds from the revolving line of credit under the Agreement to purchase the common stock. Related Provisions in the Agreement: 1) Section 2.02. Manner of Borrowing and Disbursement of Revolving Loan. Section 2.02 of the Agreement provides that, before each disbursement under the line of credit, ISI is required to submit to the Bank for its approval a written statement of the purpose of such disbursement, together with a contemplated source of repayment of the disbursement. Under Section 2.02 of the Agreement, ISI hereby requests up to $1,100,000 for the purpose of purchasing the common stock of CSI Computer Services, Inc. through the transaction described above. ISI intends to repay the funds borrowed for the Offer from the collection of receivables. 2) Section 7.03. Merger, Sale of Assets, Etc. Section 7.03 of the Agreement provides that ISI must obtain the Bank's written consent in order to enter into or be a party to a merger or consolidation, or purchase or otherwise acquire any shares of stock of, or similar interest in any other person. Under Section 7.03 of the Agreement, ISI hereby requests the Bank's consent regarding the transactions described above; specifically, the purchase of common stock of CSI through the Offer and, if necessary, a second tender offer, merger or other consolidation with CSI. 3) Section 7.07. Subsidiaries. Section 7.07 of the Agreement provides that ISI may not form or acquire any subsidiaries without the prior written consent of the Bank. Under Section 7.07 of the Agreement, ISI hereby requests the Bank's consent to acquire and operate CSI as a majority-owned subsidiary.
