At the time these notes are accepted by Instron, and exchanged for the same principal amount of Exchange Notes, I will sell, assign, and transfer to Instron all right, title and interest in and to the Outstanding Notes I have tendered. I am aware that the exchange agent also acts as the agent of Instron. By executing this document, I irrevocably appoint the exchange agent as my agent and attorney-in-fact for the tendered Outstanding Notes with full power of substitution to: 1. deliver certificates for the Outstanding Notes, or transfer ownership of the Outstanding Notes on the account books maintained by DTC, to Instron and deliver all accompanying evidences of transfer and authenticity to Instron, and 2. present the Outstanding Notes for transfer on the books of Instron, receive all benefits and exercise all rights of beneficial ownership of these Outstanding Notes, according to the terms of the Exchange Offer. The power of attorney granted in this paragraph is irrevocable and coupled with an interest. I represent and warrant that I have full power and authority to tender, sell, assign, and transfer the Outstanding Notes that I am tendering. I represent and warrant that Instron will acquire good and unencumbered title to the Outstanding Notes, free and clear of all liens, restrictions, charges and encumbrances and that the Outstanding Notes will not be subject to any adverse claim at the time Instron acquires them. I further represent that: 1. any Exchange Notes I will acquire in exchange for the Outstanding Notes I have tendered will be acquired in the ordinary course of business; 2. I have not engaged in, do not intend to engage in, and have no arrangement with any person to engage in, a distribution of any Exchange Notes issued to me; and 3. I am not an "affiliate" (as defined in Rule 405 under the Securities Act) of Instron. I understand that the Exchange Offer is being made in reliance on interpretations contained in letters issued to third parties by the staff of the Securities and Exchange Commission ("Commission"). These letters provide that the Exchange Notes issued in exchange for the Outstanding Notes in the Exchange Offer may be offered for resale, resold, and otherwise transferred by a Holder of Exchange Notes, unless that person is an "affiliate" of Instron within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act. The Exchange Notes must be acquired in the ordinary course of the Holder's business and the Holder must not be engaging in, must not intend to engage in, and must not have any arrangement or understanding with any person to participate in, a distribution of the Exchange Notes. If I am a broker-dealer that will receive Exchange Notes for my own account in exchange for Outstanding Notes that were acquired as a result of market-making activities or other trading activities (a "Participating Broker-Dealer"), I acknowledge that I will deliver a prospectus in connection with any resale of the Exchange Notes. However, by this acknowledgment and by delivering a prospectus, I will not be deemed to admit that I am an "underwriter" within the meaning of the Securities Act. If I am a Participating Broker-Dealer, I will, on a weekly basis during the 90-day period following the Expiration Date, or any longer period required if use of the prospectus has been suspended by Instron, contact Instron's Investor Relations Department at (781) 828-2500 to confirm the availability of the prospectus for delivery in connection with resales. Upon request, I will execute and deliver any additional documents deemed by the exchange agent or Instron to be necessary or desirable to complete the assignment, transfer, and purchase of the Outstanding Notes I have tendered. I understand that Instron will be deemed to have accepted validly tendered Outstanding Notes when Instron gives oral or written notice of acceptance to the exchange agent. If, for any reason, any tendered Outstanding Notes are not accepted for exchange in the Exchange Offer, certificates for those unaccepted Outstanding Notes will be returned to me without charge at the address shown below or at a different address if one is listed under "Special Delivery Instructions." Any unaccepted 4 5 Outstanding Notes which had been tendered by book-entry transfer will be credited to an account at DTC, as soon as reasonably possible after the Expiration Date. All authority granted or agreed to be granted by this letter of transmittal will survive my death, incapacity or, if I am a corporation or institution, my dissolution and every obligation under this letter of transmittal is binding upon my heirs, personal representatives, successors, and assigns. I understand that tenders of Outstanding Notes according to the procedures described in the prospectus under the heading "The Exchange Offer -- Procedures for Tendering" and in the instructions included in this document constitute a binding agreement between myself and Instron subject to the terms and conditions of the Exchange Offer. Unless I have described other instructions in this letter of transmittal under the section "Special Issuance Instructions," please issue the certificates representing Exchange Notes issued and accepted in exchange for my tendered and accepted Outstanding Notes in my name, and issue any replacement certificates for Outstanding Notes not tendered or not exchanged in my name. Similarly, unless I have instructed otherwise under the section "Special Delivery Instructions," please send the certificates representing the Exchange Notes issued in exchange for tendered and accepted Outstanding Notes and any certificates for Outstanding Notes that were not tendered or not exchanged, as well as any accompanying documents, to me at the address shown below my signature. If both "Special Payment Instructions" and "Special Delivery Instructions" are completed, please issue the certificates representing the Exchange Notes issued in exchange for my tendered and accepted Outstanding Notes in the name(s) of, and return any Outstanding Notes that were not tendered or exchanged and send such certificates to, the person(s) so indicated.

Until those transfer taxes are paid, Instron will not be required to deliver any Exchange Notes required to be delivered to, or at the direction of, such tendering Holder.

Payers must generally withhold 31% of taxable interest, dividend, and certain other payments to a payee who does not furnish a Taxpayer Identification Number to a payer. Certain penalties may also apply. PENALTIES (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you fail to furnish your Taxpayer Identification Number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect. (2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500. (3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
