Offer to Purchase for Cash by Telesoft Corp. of Up to 2,300,000 Shares of its Common Stock - ----------------------------------------------------------------------------- THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON MONDAY, MARCH 6, 2000, UNLESS THE OFFER IS EXTENDED. - ----------------------------------------------------------------------------- To Our Clients: Enclosed for your consideration are the Offer to Purchase, dated February 4, 2000, and the related Letter of Transmittal (which, as amended from time to time, together constitute the "offer") setting forth an offer by Telesoft Corp., an Arizona corporation, to purchase up to 2,300,000 shares of its common stock at a price not greater than $7.50 nor less than $7.00 per share, net to the seller in cash, as specified by tendering stockholders, upon the terms and subject to the conditions of the offer. Also enclosed herewith is certain other material related to the offer, including a letter to stockholders from Michael F. Zerbib, President and Chief Executive Officer of Telesoft. Telesoft will determine a single per share price (not greater than $7.50 nor less than $7.00 per share) that it will pay for the shares validly tendered pursuant to the offer and not withdrawn (the "Purchase Price"), taking into account the number of shares so tendered and the prices specified by tendering stockholders. Telesoft will select the lowest Purchase Price that will allow it to purchase 2,300,000 shares (or such lesser number of shares as are validly tendered at prices not greater than $7.50 nor less than $7.00 per share) validly tendered and not withdrawn pursuant to the offer. Telesoft will purchase all shares validly tendered at prices at or below the Purchase Price and not withdrawn, upon the terms and subject to the conditions of the offer, including the provisions thereof relating to proration and conditional tenders. See Sections 1 and 6 of the Offer to Purchase. We are the holder of record of shares held for your account. As such, a tender of such shares can be made only by us as the holder of record and pursuant to your instructions. The Letter of Transmittal is furnished to you for your information only and cannot be used by you to tender shares held by us for your account. Please instruct us as to whether you wish us to tender any or all of the shares held by us for your account, upon the terms and subject to the conditions set forth in the Offer to Purchase and the Letter of Transmittal. Your attention is directed to the following: 1. You may tender shares at either the price determined by you (in multiples of $0.05), not greater than $7.50 nor less than $7.00 per share, or the price determined by the "Dutch auction" tender process as indicated in the attached Instruction Form, net to you in cash. You should mark the box entitled "Shares Tendered at Price Determined by Dutch Auction" if you are willing to accept the Purchase Price resulting from the Dutch auction tender process. This could result in your receiving the minimum price of $7.00 per share. 2. The offer is for up to 2,300,000 shares. Although Telesoft has no present intention of doing so, Telesoft reserves the right, in its sole discretion but subject to certain applicable legal requirements, to purchase more than the 2,300,000 shares pursuant to the offer. The offer is not conditioned on any minimum number of shares being tendered. The offer is, however, subject to certain other conditions set forth in Section 7 of the Offer to Purchase. 3. The offer, proration period and withdrawal rights will expire at 12:00 Midnight, New York City time, on Monday, March 6, 2000, unless the offer is extended. Your instructions to us should be forwarded to us in ample time to permit us to submit a tender on your behalf. 4. As described in the Offer to Purchase, if more than 2,300,000 shares have been validly tendered at or below the Purchase Price and not withdrawn prior to the Expiration Date, as defined in Section 1 of the Offer to Purchase, Telesoft will purchase shares in the following order of priority: a. all shares validly tendered at or below the Purchase Price and not withdrawn prior to the Expiration Date by any stockholder who owns beneficially an aggregate of less than 100 shares (excluding shares attributable to individual accounts under the Telesoft Corp. Profit Sharing Plan) who validly tenders all of such shares (partial tenders will not qualify for this preference) and completes the box captioned "Odd Lots" in the Letter of Transmittal and, if applicable, the Notice of Guaranteed Delivery; b. after purchase of all of the foregoing shares, all shares conditionally tendered in accordance with Section 6 of the Offer to Purchase, for which the condition was satisfied, and all other shares tendered properly and unconditionally at prices at or below the Purchase Price and not withdrawn prior to the Expiration Date on a pro rata basis as described in Section 1 of the Offer to Purchase; and c. if necessary to permit Telesoft to purchase 2,300,000 shares, shares conditionally tendered, for which the condition was not initially satisfied, at or below the Purchase Price and not withdrawn prior to the Expiration Date, selected by random lot in accordance with Section 6 of the Offer to Purchase. 5. Tendering stockholders will not be obligated to pay any brokerage commissions or solicitation fees on Telesoft's purchase of shares in the offer. Stockholders, however, may incur fees associated with the tendering of shares held in custodial or other beneficiary accounts. Any stock transfer taxes applicable to the purchase of shares by Telesoft pursuant to the offer will be paid by Telesoft, except as otherwise provided in Instruction 7 of the Letter of Transmittal. 6. If you wish to tender portions of your shares at different prices you must complete a separate Instruction Form for each price at which you wish to tender each portion of your shares. We must submit separate Letters of Transmittal on your behalf for each price you will accept. You may not tender the same shares at more than one price. 7. If you own beneficially an aggregate of fewer than 100 shares (excluding shares attributable to individual accounts under the Telesoft Corp. Profit Sharing Plan), and you instruct us to tender at or below the Purchase Price on your behalf all such shares prior to the Expiration Date and check the box captioned "Odd Lots" in the Instruction Form, all such shares will be accepted for purchase before proration, if any, of the purchase of other tendered shares. 8. You may instruct us to tender shares on your behalf subject to the condition that a specified minimum number of your tendered shares must be purchased if any such tendered shares are purchased, as described in Section 6 of the Offer to Purchase. It is your responsibility to calculate such minimum number and you 2 are urged to consult a tax advisor. If you wish us to make a conditional tender on your behalf, you must complete the box captioned "Conditional Tenders" in the Instruction Form. Telesoft's Board of Directors has approved the offer. However, you must make your own decision whether to tender shares and, if so, how many shares to tender and the price or prices at which you are tendering your shares. Neither Telesoft nor its Board of Directors makes any recommendation to any stockholder as to whether to tender or refrain from tendering shares. See Section 10 of the Offer to Purchase for information regarding the intentions of Telesoft's directors and executive officers with respect to tendering shares pursuant to the offer. If you wish to have us tender any or all of your shares held by us for your account upon the terms and subject to the conditions set forth in the Offer to Purchase, please so instruct us by completing, executing and returning to us the attached Instruction Form. An envelope to return your instructions to us is enclosed. If you authorize tender of your shares, all such shares will be tendered unless otherwise specified on the Instruction Form. Your instructions should be forwarded to us in ample time to permit us to submit a tender on your behalf prior to the expiration of the offer. The offer is being made to all holders of shares. Telesoft is not aware of any jurisdiction where the making of the offer is not in compliance with applicable law. If Telesoft becomes aware of any jurisdiction where the making of the offer is not in compliance with any valid applicable law, Telesoft will make a good faith effort to comply with such law. If, after such good faith effort, Telesoft cannot comply with such law, the offer will not be made to (nor will tenders be accepted from or on behalf of) the holders of shares residing in such jurisdiction. In any jurisdiction in which the securities or blue sky laws require the offer to be made by a licensed broker or dealer, the offer is being made on Telesoft's behalf by or one or more registered brokers or dealers licensed under the laws of such jurisdiction. 3 INSTRUCTION FORM Offer to Purchase for Cash by Telesoft Corp. of Up to 2,300,000 Shares of its Common Stock The undersigned acknowledge(s) receipt of your letter and the enclosed Offer to Purchase, dated February 4, 2000, and the related Letter of Transmittal (which, as amended from time to time, together constitute the "offer") in connection with the offer by Telesoft Corp. to purchase up to 2,300,000 shares of its common stock at a price not greater than $7.50 nor less than $7.00 per share, net to the seller in cash, as specified by tendering stockholders, upon the terms and subject to the conditions of the offer.
