                            ------------------------
 
    Instrument Systems Corporation, a Delaware corporation (the "Company"),
invites its stockholders to tender shares of its common stock, par value $.25
per share (the "Shares"), including the associated Common Stock Purchase Rights
(the "Rights"), at prices, net to the seller in cash, not greater than $9.25 nor
less than $8.00 per Share, specified by tendering stockholders, upon the terms
and subject to the conditions set forth in this Offer to Purchase and the
related Letter of Transmittal (which together constitute the "Offer"). Unless
the Rights are redeemed by the Company prior to the Expiration Time (as defined
herein), a tender of Shares will also constitute a tender of the associated
Rights. Unless the context requires otherwise, all references herein to Shares
shall include the associated Rights.
 
    The Company will, upon the terms and subject to the conditions of the Offer,
determine a single per Share price (not greater than $9.25 nor less than $8.00
per Share) that it will pay for Shares properly tendered and not withdrawn
pursuant to the Offer (the "Purchase Price"), taking into account the number of
Shares so tendered and the prices specified by tendering stockholders. The
Company will select the lowest Purchase Price which will allow it to buy
3,000,000 Shares (or such lesser number of Shares as are properly tendered and
not withdrawn at prices not greater than $9.25 nor less than $8.00 per Share)
pursuant to the Offer. All Shares properly tendered and not withdrawn at prices
at or below the Purchase Price will be purchased at the Purchase Price, net to
the seller in cash, upon the terms and subject to the conditions of the Offer,
including the proration terms hereof. The Offer is not being made to holders of
securities convertible into or exercisable for Shares. The Company will,
however, upon the terms and subject to the conditions of the Offer, accept
tenders of Shares that are issued upon conversion or exercise of such securities
and duly tendered pursuant to the Offer.

ii 3 TO THE OWNERS OF SHARES OF THE COMMON STOCK OF INSTRUMENT SYSTEMS CORPORATION: INTRODUCTION Instrument Systems Corporation, a Delaware corporation (the "Company"), invites its stockholders to tender shares of its common stock, par value $.25 per share (the "Shares"), including the associated Common Stock Purchase Rights (the "Rights"), at prices, net to the seller in cash, not greater than $9.25 nor less than $8.00 per Share, specified by tendering stockholders, upon the terms and subject to the conditions set forth in this Offer to Purchase and the related Letter of Transmittal (which together constitute the "Offer"). Unless the Rights are redeemed by the Company, a tender of Shares will also constitute a tender of the associated Rights. Unless the context requires otherwise, all references herein to Shares shall include the associated Rights. The Company will, upon the terms and subject to the conditions of the Offer, determine a single per Share price (not greater than $9.25 nor less than $8.00 per Share) that it will pay for Shares properly tendered and not withdrawn pursuant to the Offer (the "Purchase Price"), taking into account the number of Shares so tendered and the prices specified by tendering stockholders. The Company will select the lowest Purchase Price which will allow it to buy 3,000,000 Shares (or such lesser number of Shares as are properly tendered and not withdrawn at prices not greater than $9.25 nor less than $8.00 per Share) pursuant to the Offer. All Shares properly tendered prior to the Expiration Time (as defined in Section 1) and not withdrawn at prices at or below the Purchase Price will be purchased at the Purchase Price, net to the seller in cash, upon the terms and subject to the conditions of the Offer, including the proration terms described below. THE OFFER IS NOT CONDITIONED ON ANY MINIMUM NUMBER OF SHARES BEING TENDERED. THE OFFER IS, HOWEVER, SUBJECT TO CERTAIN OTHER CONDITIONS. SEE SECTION 6. If, before the Expiration Time, more than 3,000,000 Shares (or such greater number of Shares as the Company may elect to purchase) are properly tendered and not withdrawn at or below the Purchase Price, the Company will, upon the terms and subject to the conditions of the Offer, purchase Shares first from all Odd Lot Owners (as defined in Section 2) who properly tender all their Shares at or below the Purchase Price and then on a pro rata basis from all other stockholders who properly tender Shares at or below the Purchase Price. See Sections 1 and 2. The Company will return at its own expense all Shares not purchased under the Offer, including Shares tendered and not withdrawn at prices greater than the Purchase Price and Shares not purchased because of proration. Tendering stockholders will not be obligated to pay brokerage commissions, solicitation fees or, subject to Instruction 7 of the Letter of Transmittal, stock transfer taxes on the Company's purchase of Shares pursuant to the Offer. In addition, the Company will pay all fees and expenses of Goldman, Sachs & Co. and Oppenheimer & Co., Inc. (the "Dealer Managers") and American Stock Transfer & Trust Company (the "Depositary") in connection with the Offer. See Section 16. The Company's Employee Stock Ownership Plan (the "ESOP") holds Shares in accounts for participants in the ESOP. Under the terms of the ESOP, a participant may instruct the ESOP's trustee to tender all or part of the Shares attributed to the participant's account and in each such case must specify the price or prices at which such Shares are to be tendered. See Section 3. NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION TO ANY STOCKHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING SHARES. EACH STOCKHOLDER MUST MAKE HIS OWN DECISION WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER AND AT WHICH PRICE OR PRICES. NO DIRECTOR OR OFFICER OF THE COMPANY INTENDS TO TENDER ANY SHARES PURSUANT TO THE OFFER. The Company is offering to purchase up to 3,000,000, or approximately 9%, of the Company's 33,738,036 Shares outstanding as of November 10, 1994. In addition, as of such date, (i) an 4 aggregate of 1,677,129 Shares were issuable upon the conversion of the Company's Second Preferred Stock, Series I, $.25 par value ("Second Preferred Stock"), (ii) an aggregate of 926,500 Shares were issuable upon exercise of outstanding employee stock options ("Options") and (iii) an aggregate of 226,414 Shares were issuable upon exercise of outstanding warrants ("Warrants" and, together with the Second Preferred Stock and the Options, the "Convertible Securities"). THE OFFER IS NOT BEING MADE TO HOLDERS OF THE CONVERTIBLE SECURITIES. THE COMPANY WILL, UPON THE TERMS AND SUBJECT TO THE CONDITIONS OF THE OFFER, ACCEPT TENDERS OF SHARES THAT, IN ACCORDANCE WITH THE TERMS OF SUCH CONVERTIBLE SECURITIES, ARE ISSUED UPON EXERCISE OR CONVERSION OF CONVERTIBLE SECURITIES AND DULY TENDERED PURSUANT TO THE OFFER. To the extent shares of Second Preferred Stock are converted into Shares, but the resulting Shares are not purchased pursuant to the Offer, such conversion will nevertheless be irrevocable and holders of shares of Second Preferred Stock so converted will have lost all preferential rights of Second Preferred Stock as compared to Shares (including, among other things, the priority afforded holders of shares of Second Preferred Stock with respect to the distribution of assets upon liquidation). Each holder of shares of Second Preferred Stock is urged to consult his own broker or investment or tax advisor with respect to the Offer. NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION TO ANY HOLDER OF SHARES OF SECOND PREFERRED STOCK AS TO WHETHER TO CONVERT ALL OR ANY PORTION OF HIS SHARES OF SECOND PREFERRED STOCK INTO SHARES OR AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING PURSUANT TO THE OFFER ALL OR ANY PORTION OF THE SHARES ISSUABLE UPON SUCH CONVERSION. The Company is making the Offer because its Board of Directors believes that, given the Company's businesses, assets and prospects and the current market price of the Shares, the purchase of the Shares pursuant to the Offer is an attractive investment for the Company. In addition, the Offer provides stockholders who are considering a sale of all or a portion of their Shares the opportunity to sell those Shares for cash at a price that is greater than the market price prevailing immediately prior to announcement of the Offer without the usual transaction costs associated with open-market sales. The Shares are listed and principally traded on the New York Stock Exchange ("NYSE") (Ticker Symbol: ISY). The closing per Share sales price as reported on the NYSE Composite Tape on November 7, 1994, the last trading day before the announcement of the Offer, was $7 1/2. THE COMPANY URGES STOCKHOLDERS TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE SHARES. 1. NUMBER OF SHARES; PRORATION Upon the terms and subject to the conditions of the Offer, the Company will accept for payment (and thereby purchase) 3,000,000 Shares or such lesser number of Shares as are properly tendered before the Expiration Time (and not withdrawn in accordance with Section 4) at a price (determined in the manner set forth below) not greater than $9.25 nor less than $8.00 per Share. The term "Expiration Time" means 12:00 midnight, New York City time, on Friday, December 9, 1994, unless and until the Company in its sole discretion shall have extended the period of time during which the Offer is open, in which event the term "Expiration Time" shall refer to the latest time and date at which the Offer, as so extended by the Company, shall expire. See Section 15 for a description of the Company's right to extend the time during which the Offer is open and to delay, terminate or amend the Offer. See also Section 6. Subject to Section 2, if the Offer is oversubscribed, Shares tendered at or below the Purchase Price before the Expiration Time will be eligible for proration. The proration period also expires at the Expiration Time. The Company will, upon the terms and subject to the conditions of the Offer, determine a single Purchase Price that it will pay for Shares properly tendered and not withdrawn pursuant to the Offer, taking into account the number of Shares so tendered and the prices specified by tendering stockholders. The Company will select the lowest Purchase Price which will allow it to buy 3,000,000 Shares (or such lesser number as are properly tendered and not withdrawn at prices not greater than $9.25 nor less than $8.00 per Share) pursuant to the Offer. The Company reserves the right to purchase more than 3,000,000 Shares pursuant to the Offer. If (a) the Company increases or 2 5 decreases the price to be paid for Shares, or the Company increases the number of Shares being sought and any such increase in the number of Shares being sought exceeds 2% of the outstanding Shares, or the Company decreases the number of Shares being sought and (b) the Offer is scheduled to expire less than ten business days from and including the date that notice of such increase or decrease is first published, sent or given in the manner specified in Section 15, then the Offer will be extended for at least ten business days from and including the date of such notice. For purposes of the Offer, a "business day" means any day other than a Saturday, Sunday or federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time. In accordance with Instruction 5 of the Letter of Transmittal, each stockholder desiring to tender Shares must specify the price or prices (not greater than $9.25 nor less than $8.00 per Share) at which such stockholder is willing to have the Company purchase his Shares. As promptly as practicable following the Expiration Time, the Company will determine the Purchase Price (not greater than $9.25 nor less than $8.00 per Share) that it will pay for Shares properly tendered and not withdrawn pursuant to the Offer, taking into account the number of Shares so tendered and the prices specified by tendering stockholders. All Shares purchased pursuant to the Offer will be purchased at the Purchase Price. All Shares not purchased pursuant to the Offer, including Shares tendered at prices greater than the Purchase Price and Shares not purchased because of proration, will be returned to the tendering stockholders at the Company's expense as promptly as practicable (which, in the event of proration, is expected to be approximately 12 NYSE trading days) following the Expiration Time. If the number of Shares properly tendered and not withdrawn prior to the Expiration Time at or below the Purchase Price is less than or equal to 3,000,000 Shares (or such greater number of Shares as the Company may elect to purchase), the Company will, upon the terms and subject to the conditions of the Offer, purchase at the Purchase Price all Shares so tendered. Upon the terms and subject to the conditions of the Offer, in the event that prior to the Expiration Time more than 3,000,000 Shares (or such greater number of Shares as the Company may elect to purchase) are properly tendered and not withdrawn at or below the Purchase Price, the Company will accept Shares for purchase in the following order of priority: (a) first, all Shares properly tendered and not withdrawn at or below the Purchase Price prior to the Expiration Time by any Odd Lot Owner (as defined in Section 2) who: (1) tenders all Shares beneficially owned by such Odd Lot Owner at or below the Purchase Price (partial tenders will not qualify for this preference); and (2) completes the box captioned "Odd Lots" on the Letter of Transmittal and, if applicable, on the Notice of Guaranteed Delivery; and (b) then, after purchase of all of the foregoing Shares, all other Shares properly tendered and not withdrawn at or below the Purchase Price before the Expiration Time on a pro rata basis (with adjustments to avoid purchases of fractional Shares). In the event that proration of tendered Shares is required, the Company will determine the final proration factor as promptly as practicable after the Expiration Time. Although the Company does not expect to be able to announce the final results of such proration until approximately seven NYSE trading days after the Expiration Time, it will announce preliminary results of proration by press release as promptly as practicable after the Expiration Time. Stockholders can obtain such preliminary information from the Depositary or the Dealer Managers and may be able to obtain such information from their brokers. As described in Section 14, the number of Shares that the Company will purchase from a stockholder may affect the federal income tax consequences to the stockholder of such purchase and therefore may be relevant to a stockholder's decision whether to tender Shares. The Letter of 3 6 Transmittal affords each tendering stockholder the opportunity to designate the order of priority in which Shares tendered are to be purchased in the event of proration. 2. TENDERS BY OWNERS OF FEWER THAN 100 SHARES The Company, upon the terms and subject to the conditions of the Offer, will accept for purchase, without proration, all Shares properly tendered and not withdrawn on or before the Expiration Time at or below the Purchase Price by or on behalf of stockholders who beneficially owned as of the close of business on November 7, 1994 and continue to beneficially own as of the Expiration Time, an aggregate of fewer than 100 Shares ("Odd Lot Owners"). See Section 1. To avoid proration, however, an Odd Lot Owner must properly tender at or below the Purchase Price all Shares that such Odd Lot Owner beneficially owns; partial tenders will not qualify for this preference. This preference is not available to owners of 100 or more Shares, even if such owners have separate stock certificates for fewer than 100 Shares. ANY ODD LOT OWNER WISHING TO TENDER ALL SHARES BENEFICIALLY OWNED BY HIM PURSUANT TO THIS OFFER MUST COMPLETE THE BOX CAPTIONED "ODD LOTS" ON THE LETTER OF TRANSMITTAL AND, IF APPLICABLE, ON THE NOTICE OF GUARANTEED DELIVERY. See Section 3. Stockholders owning an aggregate of less than 100 Shares whose Shares are purchased pursuant to the Offer not only will avoid the payment of brokerage commissions, but also will avoid any applicable odd-lot discounts payable on a sale of their Shares in a NYSE transaction. The special odd lot purchase rules described above do not apply to Shares held in the ESOP, and such Shares will be disregarded in determining whether a stockholder is an Odd Lot Owner. 3. PROCEDURE FOR TENDERING SHARES Proper Tender of Shares. For Shares to be properly tendered pursuant to the Offer: (a) the certificates for such Shares (or confirmation of receipt of such Shares pursuant to the procedures for book-entry transfer set forth below), together with a properly completed and duly executed Letter of Transmittal (or a facsimile thereof) with any required signature guarantees, and any other documents required by the Letter of Transmittal, must be received before the Expiration Time by the Depositary at its address set forth on the back cover of this Offer to Purchase; or (b) the tendering stockholder must comply with the guaranteed delivery procedure set forth below. Unless the Rights are redeemed prior to the Expiration Time, holders of Shares are required to tender one Right for each Share tendered in order to effect a valid tender of such Share. Unless and until Rights Certificates (as defined in Section 11) are issued, a tender of Shares pursuant to the Offer will constitute a tender of the associated Rights evidenced by the certificate for such Shares. If Rights Certificates are issued, holders of Shares will be required to tender Rights Certificates representing a number of Rights equal to the number of Shares tendered. If, after Rights Certificates are issued, a stockholder sells the Rights separately from the Shares, the selling stockholder will be unable to tender Shares unless the stockholder reacquires Rights to tender with the Shares. As specified in Instruction 5 of the Letter of Transmittal, each stockholder desiring to tender Shares pursuant to the Offer must properly indicate in the section captioned "Price (In Dollars) Per Share At Which Shares Are Being Tendered" on the Letter of Transmittal the price (in multiples of $.125) at which his Shares are being tendered, except that an Odd Lot Owner may check the box in the section of the Letter of Transmittal entitled "Odd Lots" indicating that he is tendering all of his Shares at the Purchase Price. Stockholders desiring to tender Shares at more than one price must complete separate Letters of Transmittal for each price at which Shares are being tendered, except that the same Shares cannot be tendered (unless properly withdrawn previously in accordance with the terms of the Offer) at more than one price. IN ORDER TO PROPERLY TENDER SHARES, ONE AND ONLY ONE PRICE BOX MUST BE CHECKED IN THE APPROPRIATE SECTION ON EACH LETTER OF TRANSMITTAL. 4 7 It is a violation of Rule 14e-4 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), for a person acting alone or in concert with others, directly or indirectly, to tender Shares for his own account unless at the time of tender and at the Expiration Time he has a "net long position" equal to or greater than the amount tendered in (i) the Shares and will deliver or cause to be delivered such Shares for the purpose of tender to the Company within the period specified in the Offer or (ii) other securities immediately convertible into, exercisable for or exchangeable into Shares ("equivalent securities") and, upon the acceptance of his tender, will acquire such Shares by conversion, exchange or exercise of such securities to the extent required by the terms of the Offer and will deliver or cause to be delivered such Shares so acquired for the purpose of tender to the Company within the period specified in the Offer. Rule 14e-4 also provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person. A tender of Shares made pursuant to any method of delivery set forth herein will constitute a binding agreement between the tendering stockholder and the Company upon the terms and subject to the conditions of the Offer, including the tendering stockholder's representation and warranty that (i) such stockholder has a "net long position" in Shares or equivalent securities at least equal to the Shares being tendered within the meaning of Rule 14e-4 and (ii) such tender of Shares complies with Rule 14e-4. Signature Guarantees. No signature guarantee is required on the Letter of Transmittal if the Letter of Transmittal is signed by the registered holder of the Shares (which term, for purposes of this Section, includes any participant in The Depository Trust Company, Midwest Securities Trust Company or Philadelphia Depository Trust Company (collectively, the "Book-Entry Transfer Facilities") whose name appears on a security position listing as the holder of the Shares) tendered therewith, and payment and delivery are to be made directly to such registered holder, or if Shares are tendered for the account of a member firm of a registered national securities exchange, a member of the National Association of Securities Dealers, Inc. or a commercial bank or trust company having an office, branch or agency in the United States (each such entity being hereinafter referred to as an "Eligible Institution"). In all other cases, all signatures on the Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 1 of the Letter of Transmittal. If a certificate representing Shares is registered in the name of a person other than the signer of a Letter of Transmittal, or if payment is to be made, or Shares not purchased or tendered are to be issued, to a person other than the registered holder, the certificate must be endorsed or accompanied by an appropriate stock power, in either case signed exactly as the name of the registered holder appears on the certificate, with the signature on the certificate or stock power guaranteed by an Eligible Institution. In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of certificates for such Shares (or a timely confirmation of a book-entry transfer of such Shares into the Depositary's account at one of the Book-Entry Transfer Facilities), a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and any other documents required by the Letter of Transmittal. Method of Delivery. THE METHOD OF DELIVERY OF ALL DOCUMENTS, INCLUDING SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS, IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. Federal Income Tax Withholding. To prevent backup federal income tax withholding equal to 31% of the gross payments made pursuant to the Offer, each stockholder who does not otherwise establish an exemption from such withholding must notify the Depositary of such stockholder's correct taxpayer identification number (or certify that such taxpayer is awaiting a taxpayer identification number) and provide certain other information by completing the Substitute Form W-9 included in the Letter of Transmittal. Foreign stockholders who are individuals must submit Form W-8, certifying non-United States status, in order to avoid backup withholding. The Depositary will withhold 30% of the gross payments payable to a foreign stockholder unless the Depositary determines that a reduced rate of withholding or an exemption from withholding is 5 8 applicable. For this purpose, a foreign stockholder is a stockholder that is not (i) a citizen or resident of the United States, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States or any political subdivision thereof or (iii) any estate or trust the income of which is subject to United States federal income taxation regardless of the source of such income. The Depositary will determine a stockholder's status as a foreign stockholder and eligibility for a reduced rate of, or an exemption from, withholding by reference to the stockholder's address and to any outstanding certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., Form 1001 or Form 4224) unless facts and circumstances indicate that such reliance is not warranted. A foreign stockholder who has not previously submitted the appropriate certificates or statements with respect to a reduced rate of, or exemption from, withholding for which such stockholder may be eligible should consider doing so in order to avoid overwithholding. A foreign stockholder may be eligible to obtain a refund of tax withheld if such stockholder meets one of the three tests for capital gain or loss treatment described in Section 14 or is otherwise able to establish that no tax or a reduced amount of tax was due. For a discussion of certain other federal income tax consequences to tendering stockholders, see Section 14. Book-Entry Delivery. The Depositary will establish an account with respect to the Shares at each of the Book-Entry Transfer Facilities for purposes of the Offer within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in a Book-Entry Transfer Facility's system may make book-entry delivery of the Shares by causing such facility to transfer such Shares into the Depositary's account in accordance with such facility's procedure for such transfer. Even though delivery of Shares may be effected through book-entry transfer into the Depositary's account at one of the Book-Entry Transfer Facilities, a properly completed and duly executed Letter of Transmittal (or a facsimile thereof), with any required signature guarantees and other required documents must, in any case, be transmitted to and received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Time, or the guaranteed delivery procedure set forth below must be followed. Delivery of the Letter of Transmittal and any other required documents to one of the Book-Entry Transfer Facilities does not constitute delivery to the Depositary. Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to the Offer and such stockholder's certificates are not immediately available (or the procedures for book-entry transfer cannot be completed on a timely basis) or time will not permit all required documents to reach the Depositary before the Expiration Time, such Shares may nevertheless be tendered provided that all of the following conditions are satisfied: (a) such tender is made by or through an Eligible Institution; (b) the Depositary receives (by hand, mail, telegram or facsimile transmission), on or prior to the Expiration Time, a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form the Company has provided with this Offer to Purchase (indicating the price at which the Shares are being tendered), including a guarantee by an Eligible Institution in the form set forth in such Notice; and (c) the certificates for all tendered Shares in proper form for transfer (or confirmation of book-entry transfer of such Shares into the Depositary's account at one of the Book-Entry Transfer Facilities), together with a properly completed and duly executed Letter of Transmittal (or a facsimile thereof) and any other documents required by the Letter of Transmittal, are received by the Depositary within five NYSE trading days after the date the Depositary receives such Notice of Guaranteed Delivery. Employee Stock Ownership Plan. As of November 9, 1994, the Company's Employee Stock Ownership Plan (the "ESOP") owned 2,610,618 Shares, of which 2,344,185 were allocated to the accounts of the ESOP participants. Shares allocated to participants' accounts will, subject to the 6 9 limitations of the Employee Retirement Income Security Act of 1974, as amended, and applicable regulations thereunder ("ERISA"), be tendered by U.S. Trust Company of California, N.A., as the Trustee of the ESOP, according to the instructions of participants to the Trustee. Decisions as to whether to tender Shares not allocated to participants' accounts and allocated Shares for which the Trustee has not received timely instructions from participants will be made by the Trustee subject to the terms of the ESOP and ERISA. The Trustee will make available to the participants whose accounts hold allocated Shares all documents furnished to the stockholders in connection with the Offer generally. Each such participant will also receive a form upon which the participant may instruct the Trustee regarding the Offer. Each participant may direct that all, some or none of the Shares allocated to the participant's accounts be tendered. The Company will also provide additional information in a separate letter with respect to the operations of the Offer to the participants of the ESOP. Participants in the ESOP may not use the Letter of Transmittal to direct the tender of the Shares attributed to their accounts, but must use the separate form sent to them. Participants in the ESOP are urged to read the separate form and related materials carefully. Under ERISA the Company will be prohibited from purchasing any Shares from the ESOP (including Shares allocated to the accounts of participants) if the Purchase Price is less than the prevailing market price of the Shares on the date the Shares are accepted for payment pursuant to the Offer. If Shares tendered from the ESOP would have been accepted pursuant to the terms of the Offer except for this prohibition, such Shares shall automatically be deemed to be properly withdrawn. Determinations of Validity; Rejection of Shares; Waiver of Defects; No Obligation to Give Notice of Defects. All questions as to the number of Shares to be accepted, the price to be paid therefor and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by the Company, in its sole discretion, which determination shall be final and binding on all parties. The Company reserves the absolute right to reject any or all tenders it determines not to be in proper form or the acceptance of or payment for which may, in the opinion of the Company's counsel, be unlawful. The Company also reserves the absolute right to waive any of the conditions of the Offer and any defect or irregularity in the tender of any particular Shares. No tender of Shares will be deemed to be properly made until all defects or irregularities have been cured or waived. None of the Company, the Dealer Managers, the Depositary or any other person is or will be obligated to give notice of any defects or irregularities in tenders, and none of them will incur any liability for failure to give any such notice. 4. WITHDRAWAL RIGHTS Except as otherwise provided in this Section 4, a tender of Shares pursuant to the Offer is irrevocable. Shares tendered pursuant to the Offer may be withdrawn at any time before the Expiration Time and, unless theretofore accepted for payment by the Company as provided in this Offer to Purchase, may also be withdrawn after 12:00 midnight, New York City time, on Tuesday, January 10, 1995. For a withdrawal to be effective, the Depositary must timely receive (at its address set forth on the back cover of this Offer to Purchase) a written, telegraphic or facsimile transmission notice of withdrawal. Such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder, if different from that of the person who tendered such Shares. If the certificates have been delivered or otherwise identified to the Depositary, then, prior to the release of such certificates, the tendering stockholder must also submit the serial numbers shown on the particular certificates evidencing the Shares and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution (except in the case of Shares tendered by an Eligible Institution). If Shares have been tendered pursuant to the procedure for book-entry transfer set forth in Section 3, the notice of withdrawal must specify the name and the number of the account at the applicable Book-Entry Transfer Facility to be credited with the withdrawn Shares and otherwise comply with the proce- 7 10 dures of such facility. All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by the Company, in its sole discretion, which determination shall be final and binding on all parties. None of the Company, the Dealer Managers, the Depositary or any other person is or will be obligated to give any notice of any defects or irregularities in any notice of withdrawal, and none of them will incur any liability for failure to give any such notice. Any Shares properly withdrawn will thereafter be deemed not tendered for purposes of the Offer. Withdrawn Shares may, however, be retendered before the Expiration Time by again following any of the procedures described in Section 3. If the Company extends the Offer, is delayed in its purchase of Shares or is unable to purchase Shares pursuant to the Offer for any reason, then, without prejudice to the Company's rights under the Offer, the Depositary may, subject to applicable law, retain on behalf of the Company all tendered Shares, and such Shares may not be withdrawn except to the extent tendering stockholders are entitled to withdrawal rights as described in this Section 4. 5. PURCHASE OF SHARES AND PAYMENT OF PURCHASE PRICE Upon the terms and subject to the conditions of the Offer, the Company will determine the Purchase Price it will pay for Shares properly tendered and not withdrawn pursuant to the Offer, taking into account the number of Shares tendered and the prices specified by tendering stockholders, and will accept for payment (and thereby purchase) Shares properly tendered and not withdrawn at or below the Purchase Price as soon as practicable after the Expiration Time. For purposes of the Offer, the Company will be deemed to have accepted for payment (and therefore purchased), subject to proration, Shares which are properly tendered and not withdrawn at or below the Purchase Price when, as and if it gives oral or written notice to the Depositary of its acceptance of such Shares for payment pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, the Company will purchase and pay a single Purchase Price for all of the Shares accepted for payment pursuant to the Offer as soon as practicable after the Expiration Time. In all cases, payment for Shares accepted for payment pursuant to the Offer will be made promptly (subject to possible delay in the event of proration) but only after timely receipt by the Depositary of certificates for Shares (or of a confirmation of a book-entry transfer of such Shares into the Depositary's account at one of the Book-Entry Transfer Facilities), a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and any other required documents. Payment for Shares purchased pursuant to the Offer will be made by depositing the aggregate Purchase Price therefor with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payment from the Company and transmitting payment to the tendering stockholders. In the event of proration, the Company will determine the proration factor and pay for those tendered Shares accepted for payment as soon as practicable after the Expiration Time. However, the Company does not expect to be able to announce the final results of any such proration until approximately seven NYSE trading days after the Expiration Time. Certificates for all Shares not purchased, including all Shares tendered at prices greater than the Purchase Price and Shares not purchased due to proration, will be returned (or, in the case of Shares tendered by book-entry transfer, such Shares will be credited to the account maintained with one of the Book-Entry Transfer Facilities by the participant therein who so delivered such Shares) as promptly as practicable following the Expiration Time or termination of the Offer without expense to the tendering stockholder. Under no circumstances will the Company pay interest on the Purchase Price. In addition, if certain events occur, the Company may not be obligated to purchase Shares pursuant to the Offer. See Section 6. The Company will pay all stock transfer taxes, if any, payable on the transfer to it of Shares purchased pursuant to the Offer; provided, however, that if payment of the Purchase Price is to be made to, or (in the circumstances permitted by the Offer) if unpurchased Shares are to be 8 11 registered in the name of, any person other than the registered holder, or if tendered certificates are registered in the name of any person other than the person signing the Letter of Transmittal, the amount of all stock transfer taxes, if any (whether imposed on the registered holder or such other person), payable on account of the transfer to such person will be deducted from the Purchase Price unless evidence satisfactory to the Company of the payment of such taxes or exemption therefrom is submitted. See Instruction 7 of the Letter of Transmittal. ANY TENDERING STOCKHOLDER OR OTHER PAYEE WHO FAILS TO COMPLETE FULLY AND SIGN THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL (OR, IN THE CASE OF A FOREIGN INDIVIDUAL, A FORM W-8) MAY BE SUBJECT TO REQUIRED FEDERAL INCOME TAX WITHHOLDING OF 31% OF THE GROSS PROCEEDS PAID TO SUCH STOCKHOLDER OR OTHER PAYEE PURSUANT TO THE OFFER. SEE SECTION 3. 6. CERTAIN CONDITIONS OF THE OFFER Notwithstanding any other provision of the Offer, the Company, subject to Rule 13e-4(f) of the Exchange Act, shall not be required to accept for payment, purchase or pay for any Shares tendered, and may terminate or amend the Offer if at any time after November 9, 1994, and at or before the Expiration Time, any of the following events shall have occurred (as determined by the Company in good faith) which makes it inadvisable for the Company, in its reasonable judgment, to proceed with the Offer or with such purchase or payment: (a) there shall have been threatened, instituted or pending before any court, agency, authority or other tribunal any action, suit or proceeding by any government or governmental, regulatory or administrative agency or authority or by any other person, domestic or foreign, or any judgment, order or injunction entered, enforced or deemed applicable by any such court, authority, agency or tribunal, which: (i) challenges or seeks to make illegal, or to delay or otherwise directly or indirectly to restrain, prohibit or otherwise affect the making of the Offer, the acquisition of Shares pursuant to the Offer or is otherwise related in any manner to, or otherwise affects, the Offer; or (ii) could, in the sole judgment of the Company, materially affect the business, condition (financial or other), income, operations or prospects of the Company and its subsidiaries, taken as a whole, or otherwise materially impair in any way the contemplated future conduct of the business of the Company and its subsidiaries, taken as a whole, or materially impair the Offer's contemplated benefits to the Company; or (b) there shall have been any action threatened or taken, or any approval withheld, or any statute, rule or regulation invoked, proposed, sought, promulgated, enacted, entered, amended, enforced or deemed to be applicable to the Offer or the Company or any of its subsidiaries, by any government or governmental, regulatory or administrative authority or agency or tribunal, domestic or foreign, which, in the sole judgment of the Company, would or might directly or indirectly result in any of the consequences referred to in clause (i) or (ii) of paragraph (a) above; or (c) there shall have occurred: (i) the declaration of any banking moratorium or any suspension of payments in respect of banks in the United States (whether or not mandatory); (ii) any general and protracted suspension of trading in, or limitation on prices for, securities on any United States national securities exchange or in the over-the-counter market; (iii) the commencement of a war, armed hostilities or any other national or international crisis directly or indirectly involving the United States; 9 12 (iv) any limitation (whether or not mandatory) by any governmental, regulatory or administrative agency or authority on, or any event which, in the sole judgment of the Company, might materially affect, the extension of credit by banks or other lending institutions in the United States; (v) any significant decrease in the market price of the Shares or in the market prices of equity securities generally in the United States or any change in the general political, market, economic or financial conditions in the United States or abroad that could have in the sole judgment of the Company a material adverse effect on the business, condition (financial or otherwise), income, operations or prospects of the Company and its subsidiaries, taken as a whole, or on the trading in the Shares; (vi) in the case of any of the foregoing existing at the time of the commencement of the Offer, a material acceleration or worsening thereof; or (vii) any decline in either the Dow Jones Industrial Average (3,831.75 at the close of business on November 9, 1994) or the Standard and Poor's Index of 400 Industrial Companies (554.02 at the close of business on November 9, 1994) by an amount in excess of 10% measured from the close of business on November 9, 1994; or (d) any change shall occur or be threatened in the business, condition (financial or other), income, operations or prospects of the Company and its subsidiaries, taken as a whole, which in the sole judgment of the Company may have a material adverse effect on the Company and its subsidiaries taken as a whole; or (e) a tender or exchange offer for any or all of the Shares (other than the Offer), or any merger, business combination or other similar transaction with or involving the Company or any subsidiary, shall have been proposed, announced or made by any person; or (f) any entity, "group" (as that term is used in Section 13(d)(3) of the Exchange Act) or person (other than entities, groups or persons, if any, who have filed with the Securities and Exchange Commission (the "Commission") on or before November 9, 1994 a Schedule 13G or a Schedule 13D with respect to any of the Shares) shall have acquired or proposed to acquire beneficial ownership of more than 5% of the outstanding Shares; or (g) any entity, group or person who has filed with the Commission on or before such date a Schedule 13G or a Schedule 13D with respect to the Shares shall have acquired, or proposed to acquire, beneficial ownership of additional Shares constituting more than 2% of the outstanding Shares or shall have been granted any option or right to acquire beneficial ownership of more than 2% of the outstanding Shares; or (h) any person or group shall have filed a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 reflecting an intent to acquire the Company or any of its Shares. The foregoing conditions are for the Company's sole benefit and may be asserted by the Company regardless of the circumstances giving rise to any such condition (including any action or inaction by the Company) or may be waived by the Company in whole or in part. The Company's failure at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time. Any determination by the Company concerning the events described in this Section 6 and any related judgment or decision by the Company regarding the inadvisability of proceeding with the purchase of or payment for any Shares tendered shall be final and shall be binding on all parties. 10 13 7. PRICE RANGE OF SHARES; DIVIDENDS; OPEN-MARKET PURCHASES The Shares are currently traded principally on the NYSE. Until February 2, 1993, the Shares were traded principally on the American Stock Exchange. The following table sets forth for the periods indicated the high and low sales prices per Share on the NYSE Composite Tape (for the period beginning February 3, 1993) or on the American Stock Exchange (for the period ended February 2, 1993) for each of the quarters in the Company's fiscal year ended September 30, as reported in published financial sources:
HIGH LOW ---- --- FISCAL 1993 Quarter ended December 31, 1992..................................... $6 1/4 $4 1/8 Quarter ended March 31, 1993........................................ 7 3/8 6 Quarter ended June 30, 1993......................................... 8 1/8 6 Quarter ended September 30, 1993.................................... 8 3/4 6 1/4 FISCAL 1994 Quarter ended December 31, 1993..................................... 9 1/8 8 Quarter ended March 31, 1994........................................ 9 3/4 7 3/4 Quarter ended June 30, 1994......................................... 9 6 5/8 Quarter ended September 30, 1994.................................... 8 1/8 6 7/8 FISCAL 1995 Quarter ended December 31, 1994 (through November 9, 1994)........................................ 8 1/2 7 3/8
The closing per Share sales price as reported on the NYSE Composite Tape on November 7, 1994, the last trading day before the announcement of the Offer, was $7 1/2. The closing per Share sales price as reported on the NYSE Composite Tape on November 9, 1994, the last trading day before the commencement of the Offer, was $8 3/8. THE COMPANY URGES STOCKHOLDERS TO OBTAIN CURRENT QUOTATIONS OF THE MARKET PRICE OF THE SHARES. The Company paid no dividends on the Shares during fiscal years 1993 and 1994. The Board of Directors of the Company previously has authorized the purchase by the Company of up to 4,000,000 Shares in open-market or privately negotiated transactions. As of November 9, 1994, approximately 2,300,000 Shares had been purchased pursuant to such authorization at a weighted average purchase price of $7 3/4 per Share, including 134,700 Shares purchased since September 14, 1994 at a weighted average purchase price of $7 3/4 per Share (in each case excluding commissions). All such purchases were open-market purchases on the NYSE. The Company anticipates continuing its open-market purchase program. See Section 8. 8. BACKGROUND AND PURPOSE OF THE OFFER; CERTAIN EFFECTS OF THE OFFER The Company is making the Offer because its Board of Directors believes that, given the Company's businesses, assets and prospects and the current market price of the Shares, the purchase of the Shares pursuant to the Offer is an attractive investment for the Company. In addition, the Offer provides stockholders who are considering a sale of all or a portion of their Shares the opportunity to determine the price or prices (not greater than $9.25 nor less than $8.00 per Share) at which they are willing to sell their Shares and, if any such Shares are purchased pursuant to the Offer, to sell those Shares for cash without the usual transaction costs associated with open-market sales. Any Odd Lot Owners whose Shares are purchased pursuant to the Offer not only will avoid the payment of brokerage commissions, but also will avoid any applicable odd lot discounts payable on sales of odd lots. The Offer also gives stockholders the opportunity to sell their Shares at a price that is greater than the market price prevailing immediately prior to the 11 14 announcement of the Offer. To the extent the purchase of Shares in the Offer results in a reduction in the number of stockholders of record, the costs to the Company for services to stockholders will be reduced. Stockholders who determine not to accept the Offer will increase their proportionate interest in the Company's equity, and thus in the Company's future earnings and assets, subject to the Company's right to issue additional Shares and other equity securities in the future. NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION TO ANY STOCKHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING SHARES AND NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS HAS AUTHORIZED ANY PERSON TO MAKE ANY SUCH RECOMMENDATION. EACH STOCKHOLDER MUST MAKE HIS OWN DECISION WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER AND AT WHICH PRICE OR PRICES. NO DIRECTOR OR OFFICER OF THE COMPANY INTENDS TO TENDER ANY SHARES PURSUANT TO THE OFFER. The Company may in the future purchase additional Shares on the open market, in private transactions, through tender offers or otherwise. See Section 7. Any such purchases may be on the same terms as, or on terms which are more or less favorable to stockholders than, the terms of the Offer. However, Rule 13e-4(f)(6) under the Exchange Act generally prohibits the Company and its affiliates from purchasing any Shares, other than pursuant to the Offer, until at least ten business days after the expiration or termination of the Offer. Any possible future purchases by the Company will depend on many factors, including the market price of the Shares, the results of the Offer, the Company's business and financial position and general economic and market conditions. All Shares purchased by the Company pursuant to the Offer will be retired. 9. INTERESTS OF DIRECTORS AND OFFICERS; TRANSACTIONS AND ARRANGEMENTS CONCERNING THE SHARES At November 10, 1994, the Company's directors and officers as a group beneficially owned 1,830,330 Shares (including 859,914 Shares issuable upon exercise of Options or Warrants), or approximately 5.2% of the outstanding Shares. The Company has been advised that no director or officer of the Company intends to tender any Shares pursuant to the Offer. Based upon information provided to the Company by its directors, executive officers and affiliates, to the best of the Company's knowledge, none of the directors or executive officers of the Company, nor any affiliate of any of the foregoing, has effected any transactions in the Shares during the 40 business days prior to the date hereof. Transactions in the Shares by the Company during such period are set forth in Annex A hereto. Except as set forth in this Offer to Purchase, neither the Company nor, to the Company's knowledge, any of its executive officers or directors, is a party to any contract, arrangement, understanding or relationship relating, directly or indirectly, to the Offer with any other person with respect to Shares. Except as disclosed herein, none of the Company or its executive officers or directors has current plans or proposals which relate to or would result in any extraordinary corporate transaction involving the Company or its subsidiaries, such as a merger, reorganization, sale or transfer of a material amount of its or their assets, any change in the Company's present Board of Directors or management, any material change in its present dividend policy or indebtedness or capitalization, any other material change in its business or corporate structure, any material change in its Certificate of Incorporation or Bylaws, or any actions causing a class of its equity securities to be delisted by the NYSE or to become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act, or the suspension of the Company's obligation to file reports pursuant to Section 15(d) of the Exchange Act, or any actions similar to any of the foregoing. 10. SOURCE AND AMOUNT OF FUNDS Assuming the Company purchases 3,000,000 Shares pursuant to the Offer at the maximum price of $9.25 per Share, the Company expects the maximum aggregate cost, including all fees and 12 15 expenses applicable to the Offer, would be approximately $28.5 million. The Company anticipates that all of the funds necessary to purchase Shares pursuant to the Offer and to pay the related fees and expenses will come from cash, cash equivalents and marketable securities of the Company. At November 9, 1994, the Company had cash, cash equivalents and marketable securities of approximately $50 million. 11.

15 18 NOTES TO SUMMARY PROFORMA CONSOLIDATED FINANCIAL INFORMATION The following assumptions regarding the Offer were made in determining the proforma financial information: a. The information assumes 3,000,000 Shares are purchased at $8.00 and $9.25 per Share, with the purchase being financed with cash, cash equivalents and marketable securities on hand. b. Net income has been adjusted by the after tax effect of reduced interest income on lower investable cash, cash equivalents and marketable securities as required to finance the acquisition of the Shares. c. Expenses directly related to the Offer are estimated to be $700,000 and are charged against shareholders' equity. Common Stock Purchase Rights. On April 2, 1986, the Board of Directors of the Company declared a dividend of one Right for each then outstanding Share. The distribution was payable on May 2, 1986 to the stockholders of record on May 2, 1986. Once exercisable, each Right entitles the holder to acquire from the Company one-half of a Share at an exercise price of $6.00 per one-half of a Share, subject to adjustment (the "Purchase Price"). The description and terms of the Rights are set forth in a Rights Agreement (as amended, the "Rights Agreement") between the Company and American Stock Transfer & Trust Company, as Rights Agent (the "Rights Agent"). On November 8, 1994, the Company and the Rights Agent entered into an Amendment, dated as of November 8, 1994, to the Rights Agreement. Until the earlier to occur of (i) ten days following a public announcement that a person or group of affiliated or associated persons (an "Acquiring Person") acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding Shares or (ii) ten business days (or such later date as may be determined by action of the Board of Directors prior to such time as any person becomes an Acquiring Person) following the commencement, or announcement of an intention to make, a tender offer or exchange offer by a person (other than the Company, any wholly-owned subsidiary of the Company or certain employee benefit plans) which, if consummated, would result in such person becoming an Acquiring Person (the earlier of the dates being called the "Distribution Date") for the Shares, the Rights will be evidenced by certificate with a copy of a Summary of Rights attached thereto. The Rights Agreement provides that, until the Distribution Date, the Rights will be transferred with and only with the Shares. Until the Distribution Date (or earlier redemption or expiration of the Rights), new certificates for the Shares issued after May 2, 1986 upon transfer or new issuance of the Shares will contain a notation incorporating the Rights Agreement by reference. In certain circumstances, Shares issued after the Distribution Date will be accompanied by Rights. Until the Distribution Date (or earlier redemption or expiration of the Rights), the surrender for transfer of any of the certificates for Shares outstanding, even without a copy of the Summary of Rights attached thereto, will also constitute the transfer of the Rights associated with the Shares represented by such certificate. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights ("Right Certificates") will be mailed to holders of record of the Common Stock as of the close of business on the Distribution Date and such separate Right Certificates alone will evidence the Rights. The Rights are not exercisable until the Distribution Date. The Rights will expire on May 2, 1996, unless earlier redeemed by the Company as described below. The Purchase Price payable, and the number of halves of shares of the Common Stock or other securities or property issuable, upon exercise of the Rights are subject to certain customary anti-dilution adjustments. 16 19 In the event that after the Distribution Date the Company were acquired in a merger or other business combination transaction or that 50% or more of its assets or earning power were sold, proper provision is to be made so that each holder of a Right, other than Rights that were or are beneficially owned by the Acquiring Person (which will thereafter be void), shall thereafter have the right to receive, upon the exercise thereof at the then current Purchase Price of the Right, that number of shares of common stock of the acquiring company which at the time of such transaction would have a market value of two times the Purchase Price of the Right. In the event that at any time any person shall become an Acquiring Person, proper provision shall be made so that each holder of a Right, other than Rights that were or are beneficially owned by the Acquiring Person (which will thereafter be void), shall thereafter have the right to receive, upon the exercise thereof at the then current Purchase Price, that number of Shares which at the time of such transaction would have a market value of two times the exercise price of the Right. At any time prior to the time at which a person or group of affiliated or associated persons has acquired beneficial ownership of 15% or more of the outstanding Shares (the "Shares Acquisition Date"), the Board of Directors of the Company may redeem the Rights in whole, but not in part, at a price of $.01 per Right (the "Redemption Price"). Immediately upon the action of the Board of Directors of the Company electing to redeem the Rights, the Company shall make announcement thereof, and upon such election, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. In addition, the Rights Agreement permits the Board of Directors, following the acquisition by a person or group of beneficial ownership of 15% or more of the Shares (but before an acquisition of 50% or more of the Shares), to exchange the Rights (other than Rights owned by such 15% person or group), in whole or in part, for Shares, at an exchange ratio of one Share per Right. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. The provisions of the Rights Agreement may be amended by the Board of Directors in order to cure any ambiguity or correct any defect or inconsistency and by the Continuing Directors (as defined in the Rights Agreement), prior to the Distribution Date, to make changes deemed to be in the best interests of the holders of the Rights or, after the Distribution Date, to make such other changes which do not adversely affect the interests of the holders of the Rights (excluding the interests of any Acquiring Person and its Affiliates and Associates). The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person who attempts to acquire the Company without the consent of the Board of Directors. The Rights will not affect a transaction approved by the Company prior to the existence of an Acquiring Person, because the Rights can be redeemed before the consummation of such transaction. Additional Information. The Company is subject to the informational requirements of the Exchange Act and in accordance therewith files periodic reports, proxy statements and other information with the Commission. The Company is required to disclose in such proxy statements certain information, as of particular dates, concerning the Company's directors and executive officers, their remuneration, stock options granted to them, the principal holders of the Company's securities and any material interest of such persons in transactions with the Company. The Company has also filed an Issuer Tender Offer Statement on Schedule 13E-4 with the Commission which includes certain additional information relating to the Offer. Such material can be inspected and copied at the public reference facilities of the Commission located at Room 1024, 450 Fifth Street, N.W., Washington, D.C. 20549, and at its regional offices located at 7 World Trade Center, 13th Floor, New York, New York 10048, and the Northwestern Atrium Center, 500 West Madison, Suite 1400, Chicago, Illinois 60661. Reports, proxy materials and other information about the Company should also be available at the offices of the NYSE, 20 Broad Street, New York, New York 10005. Copies may also be obtained by mail, upon payment of the Commission's customary fees, by writing to the Commission's Public Reference Section at 450 Fifth 17 20 Street, N.W., Washington, D.C. 20549. The Company's Schedule 13E-4 will not be available at the Commission's regional offices. 12. EFFECTS OF THE OFFER ON THE MARKET FOR SHARES; REGISTRATION UNDER THE EXCHANGE ACT The Company's purchase of Shares pursuant to the Offer will reduce the number of Shares that might otherwise trade publicly and is likely to reduce the number of stockholders. Nonetheless, the Company anticipates that there will still be a sufficient number of Shares outstanding and publicly traded following the Offer to ensure a continued trading market in the Shares. Based on the published guidelines of the NYSE, the Company does not believe that its purchase of Shares pursuant to the Offer will cause its remaining Shares to be delisted from such exchange. The Shares are currently "margin securities" under the rules of the Federal Reserve Board. This has the effect, among other things, of allowing brokers to extend credit on the collateral of the Shares. The Company believes that, following the purchase of Shares pursuant to the Offer, the Shares will continue to be "margin securities" for purposes of the Federal Reserve Board's margin regulations. The Shares are registered under the Exchange Act, which requires, among other things, that the Company furnish certain information to its stockholders and to the Commission and comply with the Commission's proxy rules in connection with meetings of the Company's stockholders. The Company believes that its purchase of Shares pursuant to the Offer will not result in the Shares becoming eligible for deregistration under the Exchange Act. 13. CERTAIN LEGAL MATTERS; REGULATORY AND FOREIGN APPROVALS The Company is not aware of any license or regulatory permit that appears to be material to its business that might be adversely affected by its acquisition of Shares as contemplated in the Offer or of any approval or other action by any governmental, administrative or regulatory authority or agency, domestic or foreign, that would be required for the Company's acquisition or ownership of Shares as contemplated by the Offer. Should any such approval or other action be required, the Company currently contemplates that it will seek such approval or other action. The Company cannot predict whether it may determine that it is required to delay the acceptance for payment of, or payment for, Shares tendered pursuant to the Offer pending the outcome of any such matter. There can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that the failure to obtain any such approval or other action might not result in adverse consequences to the Company's business. The Company's obligations under the Offer to accept for payment and pay for Shares are subject to certain conditions. See Section 6. 14. CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES The discussion set forth below of the U.S. federal income tax consequences of participating in the Offer is for general information only and does not purport to consider all aspects of federal income taxation that may be relevant to stockholders. The consequences to any particular stockholder may differ depending upon that stockholder's own circumstances and tax position. In addition, certain types of stockholders (including financial institutions, tax-exempt organizations, foreign persons and persons who acquired their Shares upon the exercise of employee stock options or otherwise as compensation) may be subject to special rules. The discussion does not consider the effect of any applicable foreign, state or local tax laws. EACH STOCKHOLDER IS URGED TO CONSULT HIS TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF THE OFFER TO SUCH STOCKHOLDER, INCLUDING THE APPLICATIONS OF STATE, LOCAL AND FOREIGN TAX LAWS. For purposes of this discussion, stockholders are assumed to hold their Shares as capital assets (generally, property held for investment). 18 21 The sale of Shares pursuant to the Offer will be a taxable transaction, the consequences of which will be determined under the stock redemption rules of Section 302 of the Internal Revenue Code of 1986, as amended (the "Code"). Under those rules, the entire cash proceeds received by a stockholder for his Shares pursuant to the Offer will be treated as a distribution taxable as a dividend (to the extent of the Company's available "earnings and profits"), without regard to gain or loss realized, unless the particular stockholder satisfies one of the three tests described below. Amounts includible in income as a dividend will not be reduced by the stockholder's basis in the Shares purchased pursuant to the Offer and (except as described below for corporate holdings eligible for the dividends received deduction) the stockholder's basis in those Shares will be added to the stockholder's basis in the remaining Shares. If any of the tests described below are satisfied, the stockholder will recognize capital gain or loss equal to the difference between the cash proceeds received for the Shares pursuant to the Offer and the tax basis of such Shares. Under Section 302 the entire proceeds received from the sale of Shares pursuant to the Offer will be treated as a distribution unless the sale (a) results in a "complete redemption" of the stockholder's stock in the Company, (b) is "substantially disproportionate" with respect to the stockholder or (c) is "not essentially equivalent to a dividend" with respect to the stockholder. In determining whether any of these tests is satisfied, a stockholder must take into account both Shares actually owned by such stockholder and any Shares considered as owned by such stockholder by reason of certain constructive ownership rules set forth in Section 318 of the Code. Under these rules an individual stockholder generally will be considered to own Shares which such stockholder has the right to acquire by the exercise of an option or warrant and Shares owned (and, in some cases, constructively owned) by certain members of the stockholder's family and by certain entities (such as corporations, partnerships, trusts and estates) in which such stockholder, a member of such stockholder's family or a related entity has an interest. Under Section 318, participants in the ESOP will not be considered to own Shares held by the ESOP and attributable to participants' accounts ("ESOP Shares"). ESOP participants may also actually own or be considered to own Shares ("Non-ESOP Shares") other than ESOP Shares. Whether an ESOP participant satisfies one of the three tests under Section 302 with respect to a sale of Non-ESOP Shares pursuant to the Offer is determined without regard to ESOP Shares. A sale of Shares pursuant to the Offer will result in a "complete redemption" of a stockholder's stock in the Company if, pursuant to the Offer, the Company purchases all of the Shares actually and constructively owned by the stockholder and the stockholder holds no other stock of the Company. If the stockholder's sale of Shares pursuant to the Offer includes all Shares actually owned by the stockholder but the stockholder continues to constructively own Shares held by family members, such stockholder may qualify for "complete redemption" treatment if he is eligible to elect and properly elects waiver of the constructive ownership rules regarding attribution from family members. Stockholders in this position should consult their tax advisors as to the availability of such an election. The sale of Shares pursuant to the Offer will be "substantially disproportionate" with respect to a stockholder if, immediately after the sale pursuant to the Offer, such stockholder's actual and constructive percentage ownership of Shares is less than 80% of the stockholder's actual and constructive percentage ownership of Shares immediately before the purchase of Shares pursuant to the Offer. In order for the sale of Shares by a stockholder pursuant to the Offer to qualify as "not essentially equivalent to a dividend" the stockholder must experience a "meaningful reduction" in his proportionate interest in the Company as a result of such sale, taking into account the constructive ownership rules. The Internal Revenue Service has held in a published ruling that, under the particular facts of that ruling, a very small reduction in the percentage stock ownership of a stockholder constituted a "meaningful reduction" when the stockholder owned an insignificant percentage of the corporation's stock before and after a redemption and did not exercise any 19 22 control over corporate affairs. Stockholders seeking to rely on this test should consult their tax advisors as to the application of this standard to their particular situations. Stockholders should be aware that their ability to satisfy any of the foregoing tests may be affected by any proration pursuant to the Offer. While not free from doubt, it is possible that an acquisition or disposition of Shares (including market purchases and sales) substantially contemporaneous with the Offer will be taken into account in determining whether any of the three tests described above is satisfied. If none of the tests described above is satisfied with respect to a stockholder, such stockholder's receipt of cash for Shares pursuant to the Offer will be treated as a distribution, taxable as a dividend to the extent of the Company's available "earnings and profits." Any cash received in excess of such earnings and profits will be treated, first, as a non-taxable return of capital to the extent of the stockholder's basis in all of his Shares, and, thereafter, as a capital gain to the extent it exceeds the stockholder's basis. The Company anticipates, but there can be no assurance, that its available earnings and profits will be such that all amounts treated as a distribution will be taxed as a dividend. Any income which is treated as a dividend pursuant to the rules described above will be eligible for the 70% dividends received deduction generally allowable to corporate stockholders under Section 243 of the Code, subject to applicable limitations, including those relating to "debt-financed portfolio stock" under Section 246A of the Code and to the 45-day holding period requirement of Section 246 of the Code. Also, since it is expected that purchases pursuant to the Offer will not be pro rata as to all stockholders, any amount treated as a dividend to a corporate stockholder will constitute an "extraordinary dividend" subject to the provisions of Section 1059 of the Code (except as may otherwise be provided in regulations yet to be promulgated by the Treasury Department). Under Section 1059, a corporate stockholder must reduce the tax basis in all of such stockholder's stock (but not below zero) by the portion of any "extraordinary dividend" which is an allowable deduction under the dividends received deduction rules, and, if such portion exceeds the stockholder's tax basis for the stock, must treat any such excess as additional gain on the subsequent sale or other disposition of such Shares. In addition, corporate stockholders should be aware that the aggregation rules might require that other dividends received by the stockholders on the stock of the Company be treated as an additional part of the extraordinary dividend unless the two-year holding period discussed below is satisfied. Generally, a dividend with respect to a share of common stock is deemed "extraordinary" when it exceeds 10% of a corporate taxpayer's adjusted basis in that share of stock. In determining whether this threshold percentage limitation is met, all dividends that are received by a taxpayer with respect to any share of stock and that have ex-dividend dates within the same period of 85 consecutive days are treated as one dividend. Additionally, all dividends that are received by a taxpayer with respect to any share of stock and that have ex-dividend dates within the same period of 365 consecutive days are treated as extraordinary dividends if the total of these dividends exceeds 20% of the taxpayer's adjusted basis in that share of stock. All dividends paid on the shares of stock held by corporate stockholders within either aggregation period (including dividends deemed received by such stockholders upon sales pursuant to the Offer) will be counted in determining whether such dividends amount to an extraordinary dividend, unless the two-year holding period requirement discussed below is satisfied. In determining whether a dividend paid is an extraordinary dividend, a stockholder may under certain circumstances elect to use the fair market value of the stock rather than its basis for purposes of determining whether the 10% or 20% threshold is met. Except with respect to amounts paid in connection with non-pro-rata redemptions (such as those pursuant to the Offer) and also treated as dividends, no basis reduction is generally required in the case of an otherwise extraordinary dividend received with respect to stock of a corporation where the stock was held by the selling stockholder for more than two years as of the earlier of the date on which the payment of such dividend is announced, declared, or agreed to. 20 23 Corporate stockholders should consult their tax advisors as to the application of Section 1059 of the Code to the Offer. For a discussion of certain withholding tax consequences to tendering stockholders, see Section 3. THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY. EACH STOCKHOLDER IS URGED TO CONSULT SUCH STOCKHOLDER'S OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH STOCKHOLDER (INCLUDING THE APPLICABILITY AND EFFECT OF THE CONSTRUCTIVE OWNERSHIP RULES AND FOREIGN, STATE AND LOCAL TAX LAWS) OF THE SALE OF SHARES PURSUANT TO THE OFFER. 15. EXTENSION OF THE OFFER; TERMINATION; AMENDMENTS The Company expressly reserves the right, in its sole discretion, at any time or from time to time, to extend the period of time during which the Offer is open by giving oral or written notice of such extension to the Depositary, followed by a public announcement thereof no later than 9:00 a.m. New York City time, on the next business day after the previously scheduled Expiration Time. There can be no assurance that the Company will exercise its right to extend the Offer. During any such extension, all Shares previously tendered and not accepted for payment or withdrawn will remain subject to the Offer and may be accepted for payment by the Company, except to the extent that such Shares may be withdrawn as set forth in Section 4. The Company also expressly reserves the right, in its sole discretion, (i) upon the occurrence of any of the conditions specified in Section 6, (A) to delay payment for any Shares not theretofore paid for or (B) to terminate the Offer and not to accept for payment any Shares not theretofore accepted for payment or (ii) at any time or from time to time, to amend the Offer in any respect, including increasing or decreasing the number of Shares the Company may purchase or the range of prices it may pay pursuant to the Offer. Any such extension, delay, termination or amendment will be followed as promptly as practicable by a public announcement thereof. Without limiting the manner in which the Company may choose to make any public announcement, except as provided by applicable law (including Rule 13e-4(e)(2) of the Exchange Act), the Company shall have no obligation to publish, advertise or otherwise communicate any such public announcement other than by making a release to the Dow Jones News Service. If the Company makes a material change in the terms of the Offer or the information concerning the Offer, or if it waives a material condition of the Offer, the Company will extend the Offer to the extent required by Rules 13e-4(d)(2) and 13e-4(e)(2) under the Exchange Act, which require that the minimum period during which an offer must remain open following material changes in the terms of the offer or information concerning the offer (other than a change in price, a change in dealer's soliciting fee, or a change in percentage of securities sought) will depend upon the facts and circumstances, including the relative materiality of such terms or information. In a published release, the Commission has stated that in its view an offer should remain open for a minimum of five business days from the date that notice of such a material change is first published, sent or given. The Company confirms that its reservation of the right to delay payment for Shares which it has accepted for payment is limited by Rule 13e-4(f)(5) under the Exchange Act, which requires that an issuer pay the consideration offered or return the tendered securities promptly after the termination or withdrawal of a tender offer. If (i) the Company increases or decreases the price to be paid for Shares, the Company increases or decreases the Dealer Managers' soliciting fee, the Company increases the number of Shares being sought and such increase in the number of Shares being sought exceeds 2% of the outstanding Shares, or the Company decreases the number of Shares being sought, and (ii) the Offer is scheduled to expire at any time earlier than the expiration of a period ending on the tenth business day from, and including, the date that notice of such 21 24 increase or decrease is first published, sent or given, the Offer will be extended until the expiration of such period of ten business days. 16. FEES AND EXPENSES The Company has retained Goldman, Sachs & Co. and Oppenheimer & Co., Inc. as the Dealer Managers in connection with the Offer. The Dealer Managers may contact stockholders by mail, telephone, telex, telegraph and personal interviews and may request brokers, dealers and other nominee stockholders to forward materials relating to the Offer to beneficial owners. The Dealer Managers will receive, in the aggregate, a fee of $.12 per Share purchased pursuant to the Offer, subject to a minimum fee of $100,000. The Company will also reimburse the Dealer Managers for their reasonable out-of-pocket expenses relating to the Offer, including the reasonable fees and expenses of their counsel. The Company has agreed to indemnify the Dealer Managers against certain liabilities in connection with the Offer, including certain liabilities under the federal securities laws. The Company has retained American Stock Transfer & Trust Company as Depositary in connection with the Offer. The Depositary will receive reasonable and customary compensation for its services. The Company will also reimburse the Depositary for out-of-pocket expenses, including reasonable attorneys' fees, and has agreed to indemnify the Depositary against certain liabilities in connection with the Offer, including certain liabilities under the federal securities laws. The Depositary has not been retained to make solicitations or recommendations in connection with the Offer. The Company will not pay fees or commissions to any broker, dealer, commercial bank, trust company or other person (other than the Dealer Managers) for soliciting any Shares pursuant to the Offer. The Company will, however, on request, reimburse such persons for customary handling and mailing expenses incurred in forwarding materials in respect of the Offer to the beneficial owners for which they act as nominees. No such broker, dealer, commercial bank or trust company has been authorized to act as the Company's agent for purposes of the Offer. The Company will pay (or cause to be paid) any stock transfer taxes on its purchase of Shares, except as otherwise provided in Instruction 7 of the Letter of Transmittal. 17. MISCELLANEOUS The Offer is not being made to, nor will the Company accept tenders from, holders of Shares in any jurisdiction in which the Offer or its acceptance would not comply with the securities or blue sky laws of 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 the Company's behalf by the Dealer Managers or one or more registered brokers or dealers licensed under the laws of such jurisdiction.

Unless the Rights are redeemed by the Company, a tender of Shares will also constitute a tender of the associated Rights. Unless the context requires otherwise, all references herein to Shares shall include the associated Rights. Subject to, and effective on acceptance for payment of the Shares tendered hereby in accordance with, the terms of the Offer (including, if the Offer is extended or amended, the terms or conditions of any such extension or amendment), the undersigned hereby sells, assigns and transfers to or upon the order of the Company all right, title and interest in and to all Shares tendered hereby or orders the registration of such Shares tendered by book-entry transfer that are purchased pursuant to the Offer to or upon the order of the Company and hereby irrevocably constitutes and appoints the Depositary as attorney-in-fact of the undersigned with respect to such Shares, with full power of substitution (such power of attorney being an irrevocable power coupled with interest), to: (a) deliver certificates for such Shares, or transfer ownership of such Shares on the account books maintained by a Book-Entry Transfer Facility, together in either such case with all accompanying evidences of transfer and authenticity, to or upon the order of the Company, upon receipt by the Depositary, as the undersigned's agent, of the Purchase Price (as defined below) with respect to such Shares; (b) present certificates for such Shares for cancellation and transfer on the Company's books; and (c) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares, subject to the next paragraph, all in accordance with the terms of the Offer.

The certificate numbers, the number of Shares represented by such certificates, the number of Shares that the undersigned wishes to tender and the purchase price at which such Shares are being tendered should be indicated in the appropriate boxes on this Letter of Transmittal. The undersigned understands that the Company will, upon the terms and subject to the conditions of the Offer, determine a single per Share price (not greater than $9.25 nor less than $8.00 per Share) that it will pay for Shares properly tendered and not withdrawn pursuant to the Offer (the "Purchase Price"), taking into account the number of shares so tendered and the prices specified by tendering stockholders. The undersigned understands that the Company will select the lowest Purchase Price which will allow it to buy 3,000,000 Shares (or such lesser number of Shares as are properly tendered and not withdrawn at prices not greater than $9.25 nor less than $8.00 per Share) pursuant to the Offer, or such greater number of Shares as the Company may elect to purchase. The undersigned understands that all Shares properly tendered and not withdrawn at prices at or below the Purchase Price will be purchased at the Purchase Price, net to the seller in cash, upon the terms and subject to the conditions of the Offer, including its proration provisions, and that the Company will return all other Shares, including Shares tendered and not withdrawn at prices greater than the Purchase Price and Shares not purchased because of proration. The undersigned recognizes that under certain circumstances set forth in the Offer to Purchase, the Company may terminate or amend the Offer or may postpone the acceptance for payment of, or the payment for, Shares tendered or may not be required to purchase any of the Shares tendered hereby or may accept for payment fewer than all of the Shares tendered hereby. In either event, the undersigned understands that certificate(s) for any Shares not tendered or not purchased will be returned to the undersigned at the address indicated above, unless otherwise indicated under the "Special Payment Instructions" or "Special Delivery Instructions" below. The undersigned recognizes that the Company has no obligation, pursuant to the Special Payment Instructions, to transfer any certificate for Shares from the name of their registered holder, or to order the registration or transfer of such Shares tendered by book-entry transfer, if the Company purchases none of the Shares represented by such certificate or tendered by such book-entry transfer. The undersigned understands that acceptance of Shares by the Company for payment will constitute a binding agreement between the undersigned and the Company upon the terms and subject to the conditions of the Offer. The check for the Purchase Price for such of the tendered Shares as are purchased will be issued to the order of the undersigned and mailed to the address indicated above unless otherwise indicated under the Special Payment Instructions or the Special Delivery Instructions below. All authority conferred or agreed to be conferred in this Letter of Transmittal shall survive the death or incapacity of the undersigned, and any obligations of the undersigned under this Letter of Transmittal shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

GUARANTEE OF SIGNATURES.

See Instruction 6. In all other cases, an Eligible Institution must guarantee all signatures on this Letter of Transmittal. See Instruction 6. 2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY PROCEDURES.

Certificates for all physically tendered Shares, or confirmation of a book-entry transfer into the Depositary's account at a Book-Entry Transfer Facility of Shares tendered electronically, together in each case with a properly completed and duly executed Letter of Transmittal or duly executed facsimile of it, and any other documents required by this Letter of Transmittal, should be mailed or delivered to the Depositary at the appropriate address set forth herein and must be delivered to the Depositary on or before the Expiration Time (as defined in the Offer to Purchase). Delivery of documents to one of the Book-Entry Transfer Facilities does not constitute delivery to the Depositary. Stockholders whose certificates are not immediately available or who cannot deliver Shares and all other required documents to the Depositary before the Expiration Time, or whose Shares cannot be delivered on a timely basis pursuant to the procedure for book-entry transfer, may tender their Shares by or through any Eligible Institution by properly completing (including the price at which the Shares are being tendered) and duly executing and delivering a Notice of Guaranteed Delivery (or a facsimile of it) and by otherwise complying with the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase. Pursuant to such procedure, the certificates for all physically tendered Shares or book-entry confirmation, as the case may be, as well as a properly completed Letter of Transmittal and all other documents required by this Letter of Transmittal, must be received by the Depositary within five New York Stock Exchange trading days after receipt by the Depositary of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase. The Notice of Guaranteed Delivery may be delivered by hand or transmitted by telegram, facsimile transmission or mail to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in such Notice. For Shares to be properly tendered pursuant to the guaranteed delivery procedure, the Depositary must receive the Notice of Guaranteed Delivery before the Expiration Time. THE METHOD OF DELIVERY OF ALL DOCUMENTS, INCLUDING CERTIFICATES FOR SHARES, IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY. 11 The Company will not accept any alternative, conditional or contingent tenders, nor will it purchase any fractional Shares. All tendering stockholders, by execution of this Letter of Transmittal (or a facsimile of it), waive any right to receive any notice of the acceptance of their tender. 3. INADEQUATE SPACE. If the space provided in the box captioned "Description of Shares Tendered" is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate signed schedule and attached to this Letter of Transmittal. 4. PARTIAL TENDERS AND UNPURCHASED SHARES. (Not applicable to stockholders who tender by book-entry transfer.) If fewer than all of the Shares evidenced by any certificate are to be tendered, fill in the number of Shares which are to be tendered in the column entitled "Number of Shares Tendered." In such case, if any tendered Shares are purchased, a new certificate for the remainder of the Shares evidenced by the old certificate(s) will be issued and sent to the registered holder(s), unless otherwise specified in the "Special Payment Instructions" or "Special Delivery Instructions" box on this Letter of Transmittal, as soon as practicable after the Expiration Time. All Shares represented by the certificate(s) listed and delivered to the Depositary are deemed to have been tendered unless otherwise indicated. 5. INDICATION OF PRICE AT WHICH SHARES ARE BEING TENDERED. For Shares to be properly tendered, the stockholder must check the box indicating the price per Share at which he is tendering Shares under "Price (In Dollars) Per Share at Which Shares Are Being Tendered" on this Letter of Transmittal; provided, however, that an Odd Lot Owner (as defined in Instruction 8) may check the box above in the section entitled "Odd Lots" indicating that he is tendering all of his Shares at the Purchase Price. ONLY ONE BOX MAY BE CHECKED. IF MORE THAN ONE BOX IS CHECKED, OR IF NO BOX IS CHECKED (EXCEPT AS OTHERWISE PROVIDED HEREIN), THERE IS NO PROPER TENDER OF SHARES. A stockholder wishing to tender portions of his Share holdings at different prices must complete a separate Letter of Transmittal for each price at which he wishes to tender each such portion of his Shares. The same Shares cannot be tendered (unless previously properly withdrawn as provided in Section 4 of the Offer to Purchase) at more than one price. 6. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS, AND ENDORSEMENTS. (a) If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate without any change whatsoever. (b) If the Shares are registered in the names of two or more joint holders, each such holder must sign this Letter of Transmittal. (c) If any tendered Shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles of it) as there are different registrations of certificates. (d) When this Letter of Transmittal is signed by the registered holder(s) of the Shares listed and transmitted hereby, no endorsements of certificate(s) representing such Shares or separate stock powers are required unless payment is to be made, or the certificate(s) for Shares not tendered or not purchased are to be issued, to a person other than the registered holder(s). If this Letter of Transmittal is signed by a person other than the registered holder(s) of the certificate(s) listed, or if payment is to be made or certificate(s) for Shares not tendered or not purchased are to be issued to a person other than the registered holder(s), the certificate(s) must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on the certificate(s), and any signature(s) on such certificate(s) or stock power(s) must be guaranteed by an Eligible Institution. See Instruction 1. (e) If this Letter of Transmittal or any certificates or stock powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting 12 in a fiduciary or representative capacity for the registered holder(s) of the certificates listed, such persons should so indicate when signing and must submit proper evidence satisfactory to the Company of their authority so to act. 7. STOCK TRANSFER TAXES. Except as provided in this Instruction, no stock transfer tax stamps or funds to cover such stamps need accompany this Letter of Transmittal. The Company will pay or cause to be paid any stock transfer taxes payable on the transfer to it of Shares purchased pursuant to the Offer. If, however: (a) payment of the Purchase Price is to be made to any person other than the registered holder(s); (b) Shares not tendered or not accepted for purchase are to be registered in the name of any person other than the registered holder(s); or (c) tendered certificates are registered in the name of any person other than the person(s) signing this Letter of Transmittal; then the Depositary will deduct from the Purchase Price the amount of any stock transfer taxes (whether imposed on the registered holder, such other person or otherwise) payable on account of the transfer to such person unless satisfactory evidence of the payment of such taxes, or an exemption from them, is submitted. 8. ODD LOTS. As described in Section 2 of the Offer to Purchase, if the Company is to purchase less than all Shares properly tendered and not withdrawn before the Expiration Time, the Shares purchased first will consist of all Shares properly tendered and not withdrawn by any stockholder who owned beneficially as of the close of business on November 7, 1994 and who continues to own as of the Expiration Time, an aggregate of fewer than 100 Shares and who tenders all of his Shares at or below the Purchase Price (an "Odd Lot Owner"). This preference will not be available unless the box captioned "Odd Lots" is completed. 9. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If certificate(s) for Shares not tendered or not purchased and/or check(s) are to be issued in the name of a person other than the signer of the Letter of Transmittal or if such certificate(s) and/or check(s) are to be sent to someone other than the signer of the Letter of Transmittal or to the signer at a different address, the boxes captioned "Special Payment Instructions" and/or "Special Delivery Instructions" on this Letter of Transmittal should be completed and signatures must be guaranteed as described in Instructions 1 and 6. 10. ORDER OF PURCHASE IN EVENT OF PRORATION. As described in Section 1 of the Offer to Purchase, stockholders may designate the order in which their Shares are to be purchased in the event of proration. The order of purchase may have an effect on the federal income tax classification of any gain or loss on the Shares purchased. See Section 1 of the Offer to Purchase. 11. IRREGULARITIES. The Company will determine, in its sole discretion, all questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares, and its determination shall be final and binding on all parties. The Company reserves the absolute right to reject any or all tenders determined by it not to be in proper form or the acceptance of which or payment for which may, in the opinion of the Company's counsel, be unlawful. The Company also reserves the absolute right to waive any of the conditions of the Offer or any defects or irregularities in the tender of any particular Shares, and the Company's interpretation of the terms of the Offer (including these instructions) will be final and binding on all parties. No tender of Shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with tenders must be cured within such time as the Company shall determine. None of the Company, the Dealer Manager, the Depositary nor any other person is or will be obligated to give notice of any defects or irregularities in tenders, nor shall any of them incur any liability for failure to give any such notice. 13 12. QUESTIONS AND REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and requests for assistance may be directed to, or additional copies of the Offer to Purchase, the Notice of Guaranteed Delivery, and this Letter of Transmittal may be obtained from the Dealer Managers or the Depositary at their addresses and telephone numbers set forth at the end of this Letter of Transmittal or from your broker, dealer, commercial bank or trust company. 13. SUBSTITUTE FORM W-9 AND FORM W-8. Stockholders other than corporations and certain foreign individuals may be subject to backup federal income tax withholding. Each such tendering stockholder or other payee who does not otherwise establish to the satisfaction of the Depositary an exemption from backup federal income tax withholding is required to provide the Depositary with a correct taxpayer identification number ("TIN") on Substitute Form W-9 which is provided as a part of this Letter of Transmittal, and to indicate that the stockholder or other payee is not subject to backup withholding by checking the box in Part 2 of the form. For an individual, his TIN will generally be his social security number. Failure to provide the information on the form or to check the box in Part 2 of the form may subject the tendering stockholder or other payee to 31% backup federal income tax withholding on the payments made to the stockholder or other payee with respect to Shares purchased pursuant to the Offer and to a $50.00 penalty imposed by the Internal Revenue Service. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained. The box in Part 3 of the form may be checked if the tendering stockholder or other payee has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If the box in Part 3 is checked and the Depositary is not provided with a TIN within sixty (60) days, the Depositary will withhold 31% on all such payments thereafter until a TIN is provided to the Depositary. Stockholders who are foreign individuals should submit Form W-8 to certify that they are exempt from backup withholding, unless Instruction 14 applies. Form W-8 may be obtained from the Depositary. For additional information concerning Substitute Form W-9, see the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9." 14. WITHHOLDING ON FOREIGN STOCKHOLDERS. The Depositary will withhold federal income taxes equal to 30% of the gross payments payable to a foreign stockholder or his agent unless the Depositary determines that a reduced rate of withholding or an exemption from withholding is applicable. (Exemption from backup withholding does not exempt a foreign stockholder from the 30% withholding.) For this purpose, a foreign stockholder is any stockholder that is not (i) a citizen or resident of the United States, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States or any political subdivision thereof or (iii) an estate or trust the income of which is subject to United States federal income taxation regardless of the source of such income. The Depositary will determine a stockholder's status as a foreign stockholder and eligibility for a reduced rate of, or an exemption from, withholding by reference to the stockholder's address and to any outstanding certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding unless facts and circumstances indicate that reliance is not warranted. In order to obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the United States, a foreign stockholder must deliver to the Depositary a properly executed Form 4224. Such form can be obtained from the Depositary or the Dealer Manager. A foreign stockholder who has not previously submitted the appropriate certificates or statements with respect to a reduced rate of, or exemption from, withholding for which such stockholder may be eligible should consider doing so in order to avoid overwithholding. A foreign stockholder may be eligible to obtain a refund of tax withheld if such stockholder meets one of the three tests for capital gain or loss treatment described in Section 14 of the Offer to Purchase or is otherwise able to establish that no tax or reduced amount of tax was due. Foreign stockholders are urged to consult their tax advisors regarding the application of federal income tax withholding, including eligibility for a withholding tax reduction or exemption and the refund procedures. 14 15. EMPLOYEE STOCK OWNERSHIP PLAN. Participants in the Company's Employee Stock Ownership Plan may not use this Letter of Transmittal to direct the tender of Shares attributed to a participant's account, but must use the separate instruction form sent to them. IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE OF IT (TOGETHER WITH CERTIFICATE(S) FOR SHARES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR, IF APPLICABLE, THE NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY BEFORE THE EXPIRATION TIME. 15 IMPORTANT TAX INFORMATION Under United States federal income tax law, a stockholder whose tendered Shares are accepted for payment generally is required by law to provide the Depositary with such stockholder's correct TIN on Substitute Form W-9 below. If the Depositary is not provided with the correct TIN, the Internal Revenue Service may subject the stockholder or other payee to a $50 penalty. In addition, payments that are made to such stockholder or other payee with respect to Shares purchased pursuant to the Offer may be subject to backup withholding. Certain stockholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, the stockholder must submit a Form W-8, signed under penalties of perjury, attesting to the individual's exempt status. A Form W-8 can be obtained from the Depositary. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for more instructions. If backup withholding applies, the Depositary is required to withhold 31% of any such payments made to the stockholder or other payee. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained. PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on payment made to a stockholder or other payee with respect to Shares purchased pursuant to the Offer, the stockholder is required to notify the Depositary of the stockholder's correct TIN by completing the form below, certifying that the TIN provided on Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN) and that: (a) the stockholder is exempt from backup withholding; (b) the stockholder has not been notified by the Internal Revenue Service that the stockholder is subject to backup withholding as a result of failure to report all interest or dividends; or (c) the Internal Revenue Service has notified the stockholder that the stockholder is no longer subject to backup withholding. WHAT NUMBER TO GIVE THE DEPOSITARY The stockholder is required to give the Depositary the TIN (e.g., social security number or employer identification number) of the registered holder of the Shares. If the Shares are in more than one name or are not in the name of the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional guidance on which number to report. 16 PAYER'S NAME SUBSTITUTE PART 1 -- PLEASE PROVIDE YOUR TIN IN THE BOX Social Security Number FORM W-9 AT RIGHT AND CERTIFY BY SIGNING AND DATING OR ...............................

net to the seller in cash, not greater than $9.25 nor less than $8.00 per Share,
specified by tendering stockholders, upon the terms and subject to the
conditions set forth in its Offer to Purchase, dated November 10, 1994, and the
related Letter of Transmittal (which together constitute the "Offer"). Unless
the Rights are redeemed by the Company, a tender of Shares will also constitute
a tender of the associated Rights. Unless the context requires otherwise, all

     The Company will, upon the terms and subject to the conditions of the
Offer, determine a single per Share price (not greater than $9.25 nor less than

Shares so tendered and the prices specified by tendering stockholders. The
Company will select the lowest Purchase Price which will allow it to purchase
3,000,000 Shares (or such lesser number of Shares as are properly tendered and
not withdrawn at prices not greater than $9.25 nor less than $8.00 per Share)
pursuant to the Offer. All Shares properly tendered and not withdrawn at prices

at or below the Purchase Price and then on a pro rata basis from all other
stockholders whose Shares are properly tendered and not withdrawn at or below

To Our Clients:
 
     Enclosed for your consideration are the Offer to Purchase, dated November
10, 1994 and the related Letter of Transmittal (which together constitute the
"Offer") in connection with the Offer by Instrument Systems Corporation, a
Delaware corporation (the "Company"), to purchase 3,000,000 shares of its common
stock, par value $.25 per share (the "Shares"), including the associated Common
Stock Purchase Rights (the "Rights"), at prices net to the seller in cash, not
greater than $9.25 nor less than $8.00 per Share, specified by tendering
stockholders, on the terms and subject to the conditions of the Offer. Unless
the Rights are redeemed by the Company, a tender of Shares will also constitute
a tender of the associated Rights. Unless the context requires otherwise, all
references herein to Shares shall include the associated Rights.
 
     The Company will, upon the terms and subject to the conditions of the
Offer, determine a single per Share price (not greater than $9.25 nor less than
$8.00 per Share) that it will pay for the Shares properly tendered and not
withdrawn pursuant to the Offer (the "Purchase Price"), taking into account the
number of Shares so tendered and the prices specified by tendering stockholders.
The Company will select the lowest Purchase Price which will allow it to
purchase 3,000,000 Shares (or such lesser number of Shares as are properly
tendered and not withdrawn at prices not greater than $9.25 nor less than $8.00
per Share) pursuant to the Offer. All Shares properly tendered and not withdrawn
at prices at or below the Purchase Price will be purchased at the Purchase
Price, net to the seller in cash, upon the terms and subject to the conditions
of the Offer, including the proration terms thereof. The Company will return all
other Shares, including Shares tendered at prices greater than the Purchase
Price and Shares not purchased because of proration. See Section 1 of the Offer
to Purchase.
 
     If, prior to the Expiration Time (as defined in the Offer to Purchase),
more than 3,000,000 Shares (or such greater number of Shares as the Company may
elect to purchase) are properly tendered and not withdrawn, the Company will,
upon the terms and subject to the conditions of the Offer, accept Shares for
purchase first from Odd Lot Owners (as defined in the Offer to Purchase) who
properly tender their Shares at or below the Purchase Price and then on a pro
rata basis from all other stockholders whose Shares are properly tendered at or
below the Purchase Price and not withdrawn. See Section 2 of the Offer to
Purchase.

     the Shares outstanding as of November 10, 1994.

     the Purchase Price.
 
          8. If you wish to tender portions of your Share holdings at different
     prices you must complete separate instructions for each price at which you
     wish to tender each such portion of your Shares. We must submit separate
     Letters of Transmittal on your behalf for each price you will accept.
 
     If you wish to have us tender any or all of your Shares, 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 us
to tender your Shares, we will tender all such Shares unless you specify
otherwise on the attached instruction form.
 
     YOUR INSTRUCTION FORM SHOULD BE FORWARDED TO US IN AMPLE TIME TO PERMIT US
TO SUBMIT A TENDER ON YOUR BEHALF ON OR BEFORE THE EXPIRATION OF THE OFFER. THE
OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, NEW YORK
CITY TIME, ON FRIDAY, DECEMBER 9, 1994, UNLESS THE COMPANY EXTENDS THE OFFER.
 
     As described in Section 1 of the Offer to Purchase, if before the
Expiration Time a greater number of Shares is properly tendered and not
withdrawn at or below the Purchase Price than the Company will accept for
purchase, the Company will accept Shares for purchase at the Purchase Price in
the following order of priority:
 
          (a) first, all Shares properly tendered and not withdrawn at or below
     the Purchase Price before the Expiration Time by any Odd Lot Owner who:
 
             (1) tenders all Shares beneficially owned by such Odd Lot Owner at
        or below the Purchase Price (partial tenders will not qualify for this
        preference); and
 
             (2) completes the box captioned "Odd Lots" on the Letter of
        Transmittal and, if applicable, on the Notice of Guaranteed Delivery;
        and
 
          (b) then, after purchase of all of the foregoing Shares, all other
     Shares properly tendered and not withdrawn at or below the Purchase Price
     before the Expiration Time on a pro rata basis (with adjustments to avoid
     purchases of fractional Shares), as provided in the Offer to Purchase.
 
     The Company is not making the Offer to, nor will it accept tenders from or
on behalf of, owners of Shares in any jurisdiction in which the Offer or its
acceptance would violate the securities, blue sky or other laws of 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 the Company's behalf by Goldman, Sachs & Co. or Oppenheimer & Co., Inc.
or one or more registered brokers or dealers licensed under the laws of such
jurisdiction.

     The undersigned acknowledge(s) receipt of your letter and the enclosed
Offer to Purchase, dated November 10, 1994 and the related Letter of Transmittal
(which together constitute the "Offer"), in connection with the Offer by
Instrument Systems Corporation, a Delaware corporation (the "Company"), to
purchase 3,000,000 shares of its common stock, par value $.25 per share (the
"Shares"), including the associated Common Stock Purchase Rights (the "Rights"),
at prices, net to the Seller in cash, not greater than $9.25 nor less than $8.00
per Share, specified by the undersigned, upon the terms and subject to the
conditions of the Offer. Unless the Rights are redeemed by the Company, a tender
of Shares will also constitute a tender of the associated Rights. Unless the
context requires otherwise, all references herein to Shares shall include the
associated Rights.
 
     The undersigned acknowledges that the Company will, upon the terms and
subject to the conditions of the Offer, determine a single per Share price (not
greater than $9.25 nor less than $8.00 per Share) that it will pay for Shares
properly tendered and not withdrawn pursuant to the Offer (the "Purchase
Price"), taking into account the number of Shares so tendered and the prices
specified by tendering stockholders. The Company will select the lowest Purchase
Price which will allow it to purchase 3,000,000 Shares (or such lesser number of
Shares as are properly tendered and not withdrawn at prices not greater than
$9.25 nor less than $8.00 per Share) pursuant to the Offer. All Shares properly
tendered and not withdrawn at prices at or below the Purchase Price will be
purchased at the Purchase Price, net to the seller in cash, upon the terms and
subject to the conditions of the Offer, including the proration terms thereof.
The Company will return all other Shares, including Shares tendered at prices
greater than the Purchase Price and Shares not purchased because of proration.
See Section 1 of the Offer to Purchase.
 
     The undersigned hereby instruct(s) you to tender to the Company the number
of Shares indicated below or, if no number is indicated, all Shares you hold for
the account of the undersigned, at the price per Share indicated below, pursuant
to the terms and subject to the conditions of the Offer. The Company will return
Shares tendered at prices greater than the Purchase Price and Shares not
purchased because of proration.

                 [INSTRUMENT SYSTEMS CORPORATION LETTERHEAD]



 
                                               November 10, 1994
 
To Our Shareholders:
 
     Instrument Systems Corporation is offering to purchase up to 3,000,000
shares of its Common Stock from its shareholders at a cash price not greater
than $9.25 nor less than $8.00 per share. The Company is conducting the Offer
through a procedure commonly referred to as a "Dutch Auction."
 
     This procedure allows you to select the price within that price range at
which you are willing to sell your shares to the Company. Based upon the number
of shares tendered and the prices specified by the tendering shareholders, the
Company will determine the single per share price within that price range which
will allow it to buy 3,000,000 shares (or such lesser number of shares as are
properly tendered and not withdrawn at prices not greater than $9.25 or less
than $8.00). Subject to possible proration, all of the shares that are properly
tendered at prices at or below that purchase price (and are not withdrawn) will
be purchased at that purchase price, net to the selling shareholder in cash. All
other shares that have been tendered and not purchased will be returned to the
shareholder.
 
     For those shareholders who own an aggregate of fewer than 100 shares, the
Offer may represent an opportunity to sell all of their shares without any
applicable odd-lot discounts normally payable on a sale of their shares.
 
     The Offer, proration period and withdrawal rights expire at 12:00 midnight,
New York City time, on Friday, December 9, 1994, unless the Offer is extended.
 
     Neither the Company nor its Board of Directors makes any recommendation to
any shareholder as to whether to tender or refrain from tendering shares. You
must make your own decision whether to tender shares and, if so, how many shares
to tender and at which price or prices.
 
     This Offer is explained in detail in the enclosed Offer to Purchase and
Letter of Transmittal. If you want to tender your shares, the instructions on
how to tender shares are also explained in detail in the enclosed materials. I
encourage you to read these materials carefully before making any decision with
respect to the Offer.
 
                                               Very truly yours,

                          IMMEDIATE ATTENTION REQUIRED
 
                                                               November 10, 1994
 
                   RE: DIRECTION CONCERNING TENDER OF SHARES
 
DEAR ESOP PARTICIPANT:
 
     Enclosed are materials that require your immediate attention. They describe
matters directly affecting your interest in the Instrument Systems Corporation
Employee Stock Ownership Plan (ESOP). Read all the materials carefully. You will
need to complete the enclosed Direction Form and return it in the postage paid
envelope provided. THE DEADLINE FOR RECEIPT OF YOUR COMPLETED DIRECTION FORM IS
5:00 P.M., EST, WEDNESDAY, DECEMBER 7, 1994 (UNLESS EXTENDED). YOU SHOULD
COMPLETE THE FORM AND RETURN IT EVEN IF YOU DECIDE NOT TO PARTICIPATE IN THE
TRANSACTION DESCRIBED IN THE MATERIALS.
 
     The remainder of this letter summarizes the transaction and your rights and
options under the ESOP, but you also should review the more detailed explanation
provided in the other materials.
 
BACKGROUND
 
     As you no doubt have heard, Instrument Systems Corporation (Company) has
made a tender offer to purchase up to three million shares of its Common Stock.
The objectives of the purchase, and financial and other information relating to
the offer, are described in detail in the enclosed Offer to Purchase and Letter
of Transmittal, which are being provided to all stockholders of the Company.
 
     As a participant in the ESOP, you are directly affected, because the
Company's Offer to Purchase extends to the approximately 2.6 million shares of
the Company's stock currently held by the ESOP. Only U.S. Trust Company of
California, N.A. (U.S. Trust), as the Trustee of the ESOP, actually can tender
these shares for sale. However, as an ESOP participant, you have the right
pursuant to the terms of the ESOP to direct the Trustee whether or not to tender
the shares that are allocated to your ESOP Account as of September 30, 1994. If
you elect to have the Trustee tender these shares, you also are entitled to
specify the price or prices at which they should be tendered.
 
     Please note that the Trustee is the holder of record of shares allocated to
your Account as a participant in the ESOP. A tender of such shares can be made
only by the Trustee as the holder of record; however the Trustee generally must
act pursuant to your directions as explained herein. The Letter of Transmittal
is furnished to you for your information only and cannot be used by you to
tender shares allocated to your ESOP Account.
 
     THE COMPANY'S BOARD OF DIRECTORS HAS APPROVED THE MAKING OF THE OFFER TO
PURCHASE. HOWEVER, NEITHER THE COMPANY, ITS BOARD OF DIRECTORS, U.S. TRUST AS
TRUSTEE, NOR ANY OTHER PARTY MAKES ANY RECOMMENDATIONS TO PARTICIPANTS AS TO
WHETHER TO TENDER SHARES, THE PRICE AT WHICH TO TENDER, OR TO REFRAIN FROM
TENDERING SHARES. EACH PARTICIPANT MUST MAKE HIS OWN DECISION ON THESE MATTERS.
 
     To assure the confidentiality of your decision, the Company has retained
American Stock Transfer & Trust Company (American Stock) to tabulate the
directions of ESOP participants. You will note from the included envelope that
your Direction Form is to be returned to American Stock. To further assure
confidentiality and independence of all actions, the Company also has hired U.S.
Trust, as Trustee of the ESOP, to make all discretionary determinations. In
particular, the Trustee will decide whether to tender or hold shares of the ESOP
that currently have not been allocated to participants' Accounts. The Trustee
will also decide the disposition of shares that are allocated to Accounts of
participants who fail to return timely or complete directions. Finally, the
Trustee will determine whether the implementation of any participant's
directions or adherence to any ESOP provisions would be a violation of the
Employee Retirement Income Security Act of 1974, as
   2
 
amended (ERISA). Although it is not anticipated that any direction will violate
ERISA, such that the direction would have to be reversed or ignored, the
Department of Labor requires that the Trustee, as the independent fiduciary for
ESOP participants, retain this discretion.
 
HOW THE OFFER TO PURCHASE WORKS
 
     The details of the Offer to Purchase are described in the enclosed
materials, which you should review carefully. However, in broad outline, the
transaction will work as follows with respect to ESOP participants.
 
          - The Company has offered to purchase up to 3 million of its shares of
     common stock at a price not less than $8.00 nor more than $9.25 per share.
 
          - If you want any of the shares allocated to your ESOP Account sold,
     you need to direct that they be offered (or "tendered") for sale.
 
          - You also need to specify the price at which you want the shares
     tendered. That price must be at or between the two limits above.
 
          - After the deadline for the tender of shares by all stockholders,
     including the ESOP, American Stock will complete the tabulation of all
     directions.
 
          - The Company will then determine the price, at or between the two
     limits, at which the Company can purchase the number of shares that it
     wants. This is referred to as the Purchase Price.
 
          - Unless the offer is voided or discontinued in accordance with its
     terms, the Company then will buy all the shares, up to 3 million, that were
     tendered at that price or below. However, all sellers will receive the same
     Purchase Price, even if they tendered at or below the Purchase Price.
 
          - If you direct the tender of any shares at a price in excess of the
     Purchase Price as finally determined, those shares will not be purchased,
     and they will remain allocated to your ESOP Account.
 
     This form of transaction is commonly called a "Dutch Auction" and requires
some strategy on your part. For example, if you are anxious to sell, you may
want to tender your shares at a price at or near the lower limit. If you are not
sure whether or not you want to participate, but would be willing to sell at a
price above the lower limit, then you may want to specify a higher price, not to
exceed the upper limit, of course. If you do not want to sell under any
circumstances an option is provided for you to direct that shares allocated to
your ESOP Account will be held.
 
     Of course, the Trustee may override any direction that it determines to be
in violation of ERISA, as previously described. In particular, the Company will
be prohibited from purchasing shares from the ESOP if the Purchase Price, as
finally determined, is less than the prevailing market price of the shares on
the date the shares are accepted for purchase. Finally, the Company will prorate
the number of shares purchased from stockholders if there is an excess of shares
over the exact number desired at the Purchase Price as ultimately determined.
 
PROCEDURE FOR DIRECTING TRUSTEE
 
     A Direction Form for making your direction is enclosed. You must complete
this form and return it in the included envelope in time to be received by
American Stock no later than 5:00 p.m., Eastern time, on Wednesday, December 7,
1994 (unless the Offer to Purchase is extended or amended). If your form is not
received by this deadline, or if it is not fully and properly completed, the
shares in your ESOP Account will be tendered or held as decided by the Trustee.
Please note the address label on the reverse side of the Direction Form; it
indicates the number of shares allocated to your Account as of September 30,
1994. The number of shares shown on the address label includes any
   3
 
shares allocated as a result of contributions made on your behalf by the Company
for the year ended September 30, 1994.
 
     To properly complete your Direction Form, you must do the following:
 
          (1) On the face of the form, check Box 1 or 2. CHECK ONLY ONE BOX.
     Make your decision which box to check as follows:
 
        - CHECK BOX 1 if you do not want the shares allocated to your Account
          tendered for sale at any price and simply want the ESOP to continue
          holding shares allocated to your Account.
 
        - CHECK BOX 2 in all other cases and complete the table immediately
          below Box 2. (You should not complete the table if you checked Box 1.)
          Use line A of the table to specify the number of shares that you want
          to tender at each price indicated. Typically, you would elect to have
          all of the shares tendered at a single price. However, the form gives
          you the option of splitting your shares among several prices. You must
          state the number of shares to be sold at each indicated price by
          filling in the number of shares in the box immediately below the
          price. Leave a box blank if you want no shares tendered at that price.
 
          After you have specified your tender price or prices, total the number
          of shares in line A and insert the total in the box provided at the
          end of the line. Specify the number of shares, if any, that you do not
          want tendered but wish the Trustee to hold in the single box on line
          B.
 
          Finally, total the shares in the end boxes on lines A and B and insert
          the total in the box on line C. The total in this box must equal the
          number of shares allocated to your ESOP Account as shown on the
          address label on the reverse side of the Direction Form.
 
          (2) Turn the Direction Form over, date and sign it in the space
     provided.
 
          (3) Return the Direction Form promptly in the included postage prepaid
     envelope so that it is received by American Stock no later than 5:00 p.m.,
     Eastern time, on Wednesday, December 7, 1994 (unless this deadline is
     extended). Be sure to return the form even if you decide not to have the
     Trustee tender any shares. No facsimile transmittals will be accepted.
 
     Your direction will be deemed irrevocable unless withdrawn by 5:00 p.m.,
     Eastern time, on Wednesday, December 7, 1994 (unless the Offer is extended
     or amended). To be effective, a notice of withdrawal of your direction must
     be in writing and must be received by American Stock at the following
     address:
 
           AMERICAN STOCK TRANSFER & TRUST COMPANY
           40 Wall Street
           46th Floor
           New York, New York 10005
 
     Your notice must include your name, address, Social Security number, and
     the number of shares allocated to your ESOP Account. Upon receipt of your
     notice by American Stock, your previous direction will be deemed cancelled.
     You may direct the retendering of any shares in your Account by repeating
     the previous instructions for directing the tendering set forth in this
     letter.
 
INVESTMENT OF TENDER PROCEEDS
 
     For any ESOP shares that are tendered and purchased by the Company, the
Company will pay cash to the ESOP. The Trustee then will decide whether to
reinvest the proceeds in shares of the Company's stock or in alternative
investments, being guided by the ESOP's terms and the trust agreement, subject
to the limitations of ERISA. There can be no assurance that all or a portion of
the
   4
 
proceeds of the sale of shares allocated to your account will be reinvested by
the Trustee in shares of common stock of the Company.
 
     INDIVIDUAL PARTICIPANTS IN THE ESOP WILL NOT RECEIVE ANY PORTION OF THE
TENDER PROCEEDS. ALL SUCH PROCEEDS AND THE ASSETS WILL REMAIN IN THE ESOP AND
MAY BE WITHDRAWN ONLY IN ACCORDANCE WITH THE ESOP'S TERMS.
 
     No gain or loss will be recognized by participants in the ESOP for federal
income tax purposes in connection with the tender or sale of shares held in the
ESOP.
 
CONFIDENTIALITY
 
     AS MENTIONED ABOVE, BOTH AMERICAN STOCK AND U.S. TRUST WILL PROTECT THE
CONFIDENTIALITY OF YOUR DECISION AS AN ESOP PARTICIPANT. UNDER NO CIRCUMSTANCES
WILL YOUR DECISION BE DISCLOSED TO ANY DIRECTORS, OFFICERS, OR EMPLOYEES OF
INSTRUMENT SYSTEMS CORPORATION, EXCEPT TO A LIMITED NUMBER OF ADMINISTRATORS FOR
THE VERY SOLE PURPOSE OF ALLOCATING PROCEEDS TO YOUR ESOP ACCOUNT IN THE EVENT
THAT ALL OR A PORTION OF YOUR SHARES ARE SOLD.

INSTRUMENT SYSTEMS CORPORATION REPORTS RECORD OPERATING RESULTS FOR THE FOURTH QUARTER AND FISCAL YEAR AND ANNOUNCES "DUTCH AUCTION" SELF-TENDER OFFER FOR UP TO 3,000,000 SHARES OF COMMON STOCK Jericho, New York, November 8, 1994 -- Instrument Systems Corporation (NYSE:ISY) reported record operating results for the fourth quarter and fiscal year ended September 30, 1994. Net sales for the quarter increased to $141,658,000 up 8.6% over last year's $130,469,000. Income from continuing operations for the fourth quarter was a record $10,603,000 or $.29 per share compared to $9,560,000 or $.25 per share last year. Net sales for the fiscal year increased by 11.9% up to $488,957,000 from $436,949,000 last year. Income from continuing operations for the fiscal year was a record $29,705,000 or $.80 per share compared to $26,560,000 or $.70 per share for fiscal 1993. Increased sales and earnings in the building products division accounted for the increase in operating results in the fourth quarter. For fiscal 1994, earnings increased in each of the company's three core business units with significant increases in the building products and specialty plastic films units. The company also announced the acquisition of Residential Construction Specialties, Inc., an Atlanta, Georgia based installer and distributor of building products. This is the latest acquisition for the service 2 and installation segment of our building products business and will add sales of approximately $30 million per year. The Board of Directors of Instrument Systems Corporation today authorized a "Dutch Auction" self-tender offer for up to 3,000,000 shares of the company's Common Stock. The offer will commence within a week, and will be subject to the terms and conditions that will be more fully described in the offering materials. Under the terms of the offer, the company will invite shareholders to tender their shares at prices between $8.00 and $9.25, as the shareholder shall specify. Within that range the company will determine the per share price (the "Purchase Price") that will allow it to purchase 3,000,000 shares or such lesser number as may be tendered. All shares tendered at or below the Purchase Price will be purchased at the Purchase Price. If more than 3,000,000 shares are tendered at or below the Purchase Price, there will be a proration. The company has outstanding 33,738,000 shares of Common Stock and shares of Second Preferred Stock, Series I which are convertible into 1,677,000 shares of Common Stock. The offer will not be conditioned on any minimum number of shares being tendered. Goldman, Sachs & Co. and Oppenheimer & Co., Inc. are the Dealer Managers for the offer, and the Depositary will be American Stock Transfer & Trust Co. The self-tender offer is in addition to a previously announced program authorizing the purchase of up to 4,000,000 shares of the company's Common and Preferred Stock, under which approximately 2.3 million shares of Common Stock have been purchased. 3 Instrument Systems Corporation is a leading manufacturer and marketer of residential garage doors, as well as a major supplier of industrial garage doors and a range of related products for the home building and replacement markets. The company is a leader in the development and production of embossed and laminated specialty plastic films used in the baby diaper, feminine napkin, adult incontinent and surgical markets. The company also develops and manufactures information and communication systems for government and commercial markets worldwide. 4 OPERATING HIGHLIGHTS --------------------

This announcement is neither an offer to purchase nor a solicitation of an
offer to sell Shares.  The Offer is made solely by the Offer to Purchase, dated
November 10, 1994, and the related Letter of Transmittal.  Capitalized terms
not defined in this notice are defined in the Offer to Purchase.  The Offer is
not being made to, nor will tenders be accepted from or on behalf of, owners of
Shares in any jurisdiction in which making or accepting the Offer would violate
that jurisidiction's laws.  In those jurisdictions whose laws require that the
Offer be made by a licensed broker or dealer, the Offer shall be deemed to be
made on behalf of the Company by Goldman, Sachs & Co. or Oppenheimer & Co.,
Inc. as Dealer Managers, or one or more brokers or dealers registered or
licensed under the laws of such jurisdictions.

                     NOTICE OF OFFER TO PURCHASE FOR CASH


                                      BY


                        INSTRUMENT SYSTEMS CORPORATION


                  UP TO 3,000,000 SHARES OF ITS COMMON STOCK
           (INCLUDING THE ASSOCIATED COMMON STOCK PURCHASE RIGHTS)
                     AT A PURCHASE PRICE NOT GREATER THAN
                     $9.25 NOR LESS THAN $8.00 PER SHARE


        Instrument Systems Corporation, a Delaware corporation (the "Company"),
invites stockholders to tender shares of its common stock, par value $.25 per
share (the "Shares") including the associated Common Stock Purchase Rights (the
"Rights"), at prices, net to the seller in cash, not greater than $9.25 nor
less than $8.00 per Share, specified by tendering stockholders, upon the terms
and subject to the conditions set forth in the Offer to Purchase, dated
November 10, 1994 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which together constitute the "Offer").  Unless the Rights are
redeemed by the Company, a tender of Shares will also constitute a tender of
the associated Rights.  Unless the context requires otherwise, all references
herein to Shares shall include the associated Rights.

        THE OFFER IS NOT CONDITIONED ON ANY MINIMUM NUMBER OF SHARES BEING
TENDERED.

THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00
MIDNIGHT, NEW YORK CITY TIME, ON FRIDAY, DECEMBER 9, 1994, UNLESS THE OFFER IS
EXTENDED (THE "EXPIRATION TIME").

        The Company will, upon the terms and subject to the conditions of the
Offer, determine a single per Share price (not greater than $9.25 nor less
than $8.00 per Share) that it will pay for Shares properly tendered and not
withdrawn pursuant to the Offer (the "Purchase Price"), taking into account the
number of Shares so tendered and the prices specified by tendering
stockholders.  The Company will select the lowest Purchase Price which will
allow it to buy 3,000,000 Shares (or such lesser number as are properly tendered
and not withdrawn at prices not greater than $9.25 nor less than $8.00 per
Share) pursuant to the Offer, or such greater number of Shares as the Company
may elect to purchase.  All shares properly tendered and not withdrawn at
prices at or below the Purchase Price will be purchased at the Purchase Price,
net to the seller in cash, upon the terms and subject to the conditions of the
Offer, including the proration terms thereof.  For purposes of the Offer, the
Company will be deemed to have accepted for payment (and thereby purchased),
subject to proration, Shares which are properly tendered and not withdrawn at
or below the Purchase Price when, as and if it gives oral or written notice to
the Depositary of its acceptance of such Shares for payment pursuant to the
Offer.  In all cases, payment for Shares tendered and accepted for payment
pursuant to the Offer will be made only after timely receipt by the Depositary
of certificates for such Shares (or a timely confirmation of a book-entry
transfer of such Shares into the Depositary's account at one of the Book-Entry
Transfer Facilities (as defined in the Offer to Purchase)), a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) and
any other documents required by the Letter of Transmittal.

        Upon the terms and subject to the conditions of the Offer, in the event
that prior to the Expiration Time a greater number of Shares is properly
tendered and not withdrawn at or below the Purchase Price than the Company will
accept for purchase, the Company will accept Shares for purchase in the
following order of priority: (a) first, all Shares properly tendered and not
withdrawn at or below the Purchase Price by or on behalf of any stockholder who
beneficially owned as of the close of business on November 7, 1994 and
continues to beneficially own as of the Expiration Time, an aggregate of fewer
than 100 Shares, who tenders all such Shares at or below the Purchase Price
(partial tenders will not qualify for this preference) and who completes the
box captioned "Odd Lots" on the Letter of Transmittal and, if applicable, on
the Notice of Guaranteed Delivery, and (b) then, after purchase of all the
foregoing Shares, all other shares properly tendered and not withdrawn at or
below the Purchase Price before the Expiration Time on a pro rata basis (with
adjustments to avoid purchases of fractional Shares).
   2
        The Company is making the Offer because its Board of Directors believes
that, given the Company's businesses, assets and prospects and the current
market price of the Shares, the purchase of the Shares is an attractive
investment for the Company.  In addition, the Offer provides stockholders who
are considering a sale of all or a portion of their Shares the opportunity to
sell those Shares for cash at a price that is greater than the market price
prevailing immediately prior to announcement of the Offer without the usual
transaction costs associated with open-market sales.

        NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION
TO ANY STOCKHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING SHARES. 
EACH STOCKHOLDER MUST MAKE HIS OWN DECISION WHETHER TO TENDER SHARES AND, IF
SO, HOW MANY SHARES TO TENDER AND AT WHICH PRICE OR PRICES.  NO DIRECTOR OR
OFFICER OF THE COMPANY INTENDS TO TENDER ANY SHARES PURSUANT TO THE OFFER.

        The Company expressly reserves the right, in its sole discretion, at
any time or from time to time, to extend the period of time during which the
Offer is open by giving oral or written notice of such extension to the
Depositary, followed by a public announcement thereof no later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Time.

        Except as otherwise provided in the Offer, tenders of Shares pursuant
to the Offer are irrevocable.  Shares tendered pursuant to the Offer may be
withdrawn at any time before the Expiration Time and, unless theretofore
accepted for payment by the Company, may also be withdrawn after 12:00 midnight,
New York City time, on Tuesday, January 10, 1995.  For a withdrawal to be
effective, the Depositary must timely receive (at its address set forth on the
back cover of the Offer to Purchase) a written, telegraphic or facsimile
transmission notice of withdrawal.  Such notice of withdrawal must specify the
name of the person who tendered the Shares to be withdrawn, the number of
Shares to be withdrawn and the name of the registered holder, if different from
that of the person who tendered such Shares.  If the certificates have been
delivered or otherwise identified to the Depositary, then, prior to the release
of such certificates, the tendering stockholder must also submit the serial
numbers shown on the particular certificates evidencing the Shares and the
signature on the notice of withdrawal must be guaranteed by an Eligible
Institution (as defined in the Offer to Purchase) (except in the case of Shares
tendered by an Eligible Institution).  If Shares have been tendered pursuant to
the procedure for book-entry transfer set forth in Section 3 of the Offer to
Purchase, the notice of withdrawal must specify the name and number of the
account at the applicable Book-Entry Transfer Facility to be credited with the
withdrawn Shares and otherwise comply with the procedures of such facility.

        THE OFFER TO PURCHASE AND LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ BEFORE STOCKHOLDERS DECIDE WHETHER TO ACCEPT 
OR REJECT THE OFFER.  They have been mailed to record holders of Shares and 
have been furnished to brokers, banks and similar persons whose names, or the
names of whose nominees, appear on the Company's stockholder list (or, if
applicable, who are listed as participants in clearing agency's security
position listing) for transmittal to beneficial owners of Shares.

        THE INFORMATION REQUIRED TO BE DISCLOSED BY RULE 13e-4(d)(1)
PROMULGATED UNDER THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED, IS CONTAINED
IN THE OFFER TO PURCHASE AND IS INCORPORATED IN THIS NOTICE BY REFERENCE.

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9
 
SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE.
 
     Purpose of Form. -- A person who is required to file an information return
with the IRS must obtain your correct TIN to report income paid to you, real
estate transactions, mortgage interest you paid, the acquisition or abandonment
of secured property, or contributions you made to an IRA. Use Form W-9 to
furnish your correct TIN to the requester (the person asking you to furnish your
TIN) and, when applicable, (1) to certify that the TIN you are furnishing is
correct (or that you are waiting for a number to be issued), (2) to certify that
you are not subject to backup withholding, and (3) to claim exemption from
backup withholding if you are an exempt payee. Furnishing your correct TIN and
making the appropriate certifications will prevent certain payments from being
subject to backup withholding.
 
     Note: If a requester gives you a form other than a W-9 to request your TIN,
you must use the requester's form.
 
     How To Obtain a TIN. -- If you do not have a TIN, apply for one
immediately. To apply, get Form SS-5, Application for a Social Security Card
(for individuals), from your local office of the Social Security Administration,
or Form SS-4, Application for Employer Identification Number (for businesses and
all other entities), from your local IRS office.
 
     To complete Form W-9 if you do not have a TIN, write "Applied for" in the
space for the TIN in Part I (or check box 2 of Substitute Form W-9), sign and
date the form, and give it to the requester. Generally, you must obtain a TIN
and furnish it to the requester by the time of payment. If the requester does
not receive your TIN by the time of payment, backup withholding, if applicable,
will begin and continue until you furnish your TIN to the requester.
 
     Note: Writing "Applied for" (or checking box 2 of the Substitute Form W-9)
on the form means that you have already applied for a TIN OR that you intend to
apply for one in the near future.

     What Is Backup Withholding? -- Persons making certain payments to you after
1992 are required to withhold and pay to the IRS 31% of such payments under
certain conditions. This is called "backup withholding." Payments that could be
subject to backup withholding include interest, dividends, broker and barter
exchange transactions, rents, royalties, nonemployee compensation, and certain
payments from fishing boat operators, but do not include real estate
transactions.
 
     If you give the requester your correct TIN, make the appropriate
certifications, and report all your taxable interest and dividends on your tax
return, your payments will not be subject to backup withholding. Payments you
receive will be subject to backup withholding if:
 
          1. You do not furnish your TIN to the requester, or
 
          2. The IRS notifies the requester that you furnished an incorrect TIN,
     or
 
          3. You are notified by the IRS that you are subject to backup
     withholding because you failed to report all your interest and dividends on
     your tax return (for reportable interest and dividends only), or
 
          4. You do not certify to the requester that you are not subject to
     backup withholding under 3 above (for reportable interest and dividend
     accounts opened after 1983 only), or
 
          5. You do not certify your TIN. This applies only to reportable
     interest, dividend, broker, or barter exchange accounts opened after 1983,
     or broker accounts considered inactive in 1983.

     Except as explained in 5 above, other reportable payments are subject to
backup withholding only if 1 or 2 above applies. Certain payees and payments are
exempt from backup withholding and information reporting. See Payees and
Payments Exempt From Backup Withholding, below, and Example Payees and Payments
under Specific Instructions, below, if you are an exempt payee.
