Ladies and Gentlemen:

        The undersigned hereby tenders to Mountain Acquisition Sub, Inc., a Delaware corporation (the "Purchaser") and a wholly owned subsidiary of Synopsys, Inc., a Delaware corporation ("Synopsys"), the above described shares of common stock, par value $0.01 per share ("Shares"), of Monolithic System Technology, Inc., a Delaware corporation ("MoSys"), upon the terms and subject to the conditions set forth in the Purchaser's Offer to Purchase, dated March 22, 2004 (the "Offer to Purchase"), and this Letter of Transmittal (which, together with any amendments or supplements thereto or hereto, collectively constitute the "Offer"), receipt of which is hereby acknowledged.

        Upon the terms of the Offer, subject to, and effective upon, acceptance for payment of, and delivery of consideration for, the Shares tendered herewith in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Purchaser all right, title and interest in and to all the Shares that are being tendered herewith (and any and all dividends, distributions, other Shares or other securities or rights issued or issuable in respect thereof on or after March 22, 2004 (collectively, "Distributions")) and irrevocably constitutes and appoints Computershare Trust Company of New York (the "Depositary") the true and lawful agent and attorney-in-fact of the undersigned, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to the full extent of the undersigned's rights with respect to such Shares (and any and all Distributions) (i) to deliver certificates for such Shares (and any such other Shares or securities or rights) or transfer ownership of such Shares (and any and all Distributions) on the account books maintained by the book-entry transfer facility together, in any such case, with all accompanying evidences of transfer and authenticity to, or upon the order of, the Purchaser, (ii) to present such Shares (and any and all Distributions) for transfer on MoSys' books and (iii) to receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any and all Distributions), all in accordance with the terms of the Offer.

        The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered herewith (and any and all Distributions) and, when the same are accepted for payment by the Purchaser, the Purchaser will acquire good title thereto, free and clear of all liens, restrictions, claims and encumbrances, and the same will not be subject to any adverse claim. The undersigned will, upon request, execute any additional documents deemed by the Depositary or the Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered herewith (and any and all Distributions). In addition, the undersigned shall remit and transfer promptly to the Depositary for the account of the Purchaser any and all Distributions in respect of the Shares tendered hereby, accompanied by appropriate documentation of transfer, and, pending such remittance and transfer or appropriate assurance thereof, the Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of the Shares tendered hereby or deduct from such purchase price, the amount of value of such Distribution as determined by the Purchaser in its sole discretion.

        All authority conferred or agreed to be conferred pursuant to this Letter of Transmittal shall be binding upon the successors, assigns, heirs, executors, administrators and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. Except as described in the Offer to Purchase, this tender is irrevocable. The Purchaser reserves the right to require that, in order for the Shares or other securities to be deemed validly tendered, immediately upon the Purchaser's acceptance for payment of such Shares, the Purchaser must be able to exercise full voting, consent and other rights with respect to such Shares (and any and all Distributions), including voting at any meeting of MoSys' stockholders.

        By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints Rex S. Jackson as an attorney-in-fact and proxy of the undersigned, with full power of substitution and resubstitution, to vote at any annual, special, adjourned or postponed meeting of MoSys' stockholders or otherwise in such manner as such attorney-in-fact and proxy (or his substitute) shall in his sole discretion deem proper with respect to, to execute any written consent concerning any matter as such attorney-in-fact and proxy (or his substitute) shall in his sole discretion deem proper with respect to, and to otherwise act as such attorney-in-fact and proxy (or his substitute) shall in his sole discretion deem proper with respect to, the Shares tendered herewith that have been accepted for payment by the Purchaser prior to the time any such action is taken and with respect to which the undersigned is entitled to vote (and any and all Distributions). This appointment is effective when, and only to the extent that, the Purchaser accepts for payment such Shares as provided in the Offer to Purchase. This power of attorney and proxy are irrevocable and are granted in consideration of the acceptance for payment of such Shares in accordance with the terms of the Offer. Upon such acceptance for payment, all prior powers of attorney, proxies



and consents given by the undersigned with respect to the Shares tendered herewith (and any and all Distributions) will, without further action, be revoked and no subsequent powers of attorney, proxies, consents or revocations may be given (and, if given, will not be deemed effective) by the undersigned in respect of such Shares.

        The undersigned understands that the valid tender of Shares pursuant to any of the procedures described in the Offer to Purchase and in the Instructions hereto will constitute a binding agreement between the undersigned and the Purchaser upon the terms of and subject to the conditions to the Offer (and if the Offer is extended or amended, the terms of or the conditions to any such extension or amendment).

        Unless otherwise indicated herein in the box labeled "Special Payment Instructions," please deliver the check for the purchase price and/or return any certificate(s) for Shares not tendered or accepted for payment in the name(s) of the registered holder(s) indicated herein in the box labeled "Description of Shares Tendered" on the cover page of this Letter of Transmittal. Similarly, unless otherwise indicated herein in the box labeled "Special Delivery Instructions," please deliver the check for the purchase price and/or return any certificates for Shares not tendered or accepted for payment (and accompanying documents, as appropriate) to the address(es) of the registered holder(s) indicated herein in the box labeled "Description of Shares Tendered" on the cover page of this Letter of Transmittal. In the event that both of the boxes herein labeled "Special Payment Instructions" and "Special Delivery Instructions," respectively, are completed, please deliver the check for the purchase price and/or return any certificate(s) for Shares not tendered or accepted for payment (and any accompanying documents, as appropriate) in the name of, and deliver such check and/or return such certificates (and any accompanying documents, as appropriate) to, the person or persons indicated therein. Please credit any Shares tendered herewith by book-entry transfer that are not accepted for payment by crediting the account at the book-entry transfer facility. The undersigned recognizes that the Purchaser has no obligation pursuant to the Special Payment Instructions to transfer any Shares from the name of the registered holder(s) thereof if the Purchaser does not accept for payment any of the Shares so tendered.

INSTRUCTIONS
FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

        1.    Guarantee of Signatures.    No signature guarantee is required on this Letter of Transmittal if (a) this Letter of Transmittal is signed by the registered holder(s) of Shares tendered herewith, unless such registered holder(s) has completed either the box labeled "Special Payment Instructions" or the box labeled "Special Delivery Instructions" on this Letter of Transmittal or (b) such Shares are tendered for the account of a financial institution (including most banks, savings and loan associations and brokerage houses) that is a participant in the Security Transfer Agent's Medallion Program, Nasdaq Stock Market Guarantee Program or the Stock Exchange Medallion Program or by any other "eligible guarantor institution", as such term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended (each, an "Eligible Institution"). For purposes of this Instruction, a registered holder of Shares includes any participant in the book-entry transfer facilities system whose name appears on a security position listing as the owner of the Shares. In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.

        2.    Requirements of Tender.    This Letter of Transmittal is to be completed by stockholders either if certificates are to be tendered herewith or, unless an agent's message is utilized, if delivery of Shares is to be made pursuant to the procedures for book-entry transfer described in the Offer to Purchase to an account maintained by the Depositary at the book entry transfer facility. For a stockholder to validly tender Shares in the Offer, either (a) the certificate(s) representing the tendered Shares, together with this Letter of Transmittal (or a facsimile copy of it), properly completed and duly executed, together with any required signature guarantees and any other required documents, must be received by the Depositary at one of its addresses listed herein on or prior to the Expiration Date of the Offer, (b) in the case of a tender effected pursuant to a book-entry transfer (i) either this Letter of Transmittal (or a facsimile copy of it), properly completed and duly executed, together with any required signature guarantees, or an agent's message, and any other required documents, must be received by the Depositary at one of its addresses listed herein on or prior to the Expiration Date of the Offer and (ii) the Shares to be tendered must be delivered pursuant to the book-entry transfer procedures described in the Offer to Purchase and a book-entry confirmation must be received by the Depositary on or prior to the Expiration Date of the Offer or (c) the tendering stockholder must comply with the guaranteed delivery procedures described in the Offer to Purchase on or prior to the Expiration Date of the Offer.

        If a stockholder desires to tender Shares in the Offer and such stockholder's certificates representing such Shares are not immediately available, or the book-entry transfer procedures described in the Offer to Purchase cannot be completed on a timely basis, or time will not permit all required documents to reach the Depositary on or prior to the Expiration Date of the Offer, such stockholder may tender such Shares if all the following conditions are met: (i) such tender is made by or through an Eligible Institution; (ii) a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by the Purchaser, is received by the Depositary at one of its addresses listed herein on or prior to the Expiration Date of the Offer; and (iii) either (A) the certificates representing such Shares, together with this Letter of Transmittal (or a facsimile copy of it), properly completed and duly executed, and any required signature guarantees, and any other required documents, are received by the Depositary at one of its addresses listed herein within three trading days (as described below) after the date of execution of such Notice of Guaranteed Delivery or (B) in the case of a book-entry transfer effected pursuant to the book-entry transfer procedures described in the Offer to Purchase, (1) either this Letter of Transmittal (or a facsimile copy of it), properly completed and duly executed, and any required signature guarantees, or an agent's message, and any other required documents, is received by the Depositary at one of its addresses listed herein and (2) such Shares are delivered pursuant to the book-entry transfer procedures described in the Offer to Purchase and a book-entry confirmation is received by the Depositary, in each case within three trading days after the date of execution of such Notice of Guaranteed Delivery. For purposes of the foregoing, a trading day is any day on which the Nasdaq National Market is open for business.

        The method of delivery of Shares to be tendered in the Offer, this Letter of Transmittal and all other required documents, including delivery through the book-entry transfer facility, is at the election and risk of the tendering stockholder. Shares to be tendered in the Offer will be deemed delivered only when actually received by the Depositary (including, in the case of a book-entry transfer, by book-entry confirmation). If delivery of Shares is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

        No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be accepted for exchange or payment. All tendering stockholders, by execution of this Letter of Transmittal (or a facsimile copy of it), waive any right to receive any notice of the acceptance of their Shares for payment.



        3.    Inadequate Space.    If the space provided herein is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate schedule attached hereto and separately signed on each page in the same manner as this Letter of Transmittal.

        4.    Partial Tenders (Applicable to Certificate Stockholders Only).    If fewer than all the Shares evidenced by any certificate submitted are to be tendered herewith, fill in the number of Shares that are to be tendered in the column entitled "Number of Shares Tendered." In any such case, new certificate(s) for the remainder of the Shares that were evidenced by the old certificate(s) will be sent to the registered holder(s), unless otherwise provided in the appropriate box on this Letter of Transmittal, as soon as practicable after the acceptance for payment of, and delivery of the check for the purchase price for, the Shares tendered herewith. All Shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

        5.    Signatures on Letter of Transmittal, Stock Powers and Endorsements.    If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered herewith, the signature(s) must correspond with the name(s) as written on the face of the certificate(s) without any change whatsoever.

        If any of the Shares tendered herewith are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal.

        If any tendered Shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter of Transmittal as there are different registrations of certificates.

        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 in a fiduciary or representative capacity, such persons should so indicate when signing and proper evidence, satisfactory to the Purchaser, of their authority so to act must be submitted.

        When this Letter of Transmittal is signed by the registered owner(s) of the Shares tendered herewith, no endorsements of certificates or separate stock powers are required unless delivery of consideration is to be made to, or certificates for Shares not tendered or accepted for payment are to be issued to, a person other than the registered owner(s). Signatures on such certificates or stock powers must be guaranteed by an Eligible Institution.

        If this Letter of Transmittal is signed by a person other than the registered owner(s) of certificate(s) listed on the cover page, such certificate(s) must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered owner(s) appear on such certificate(s) and the signatures on such certificates or stock powers must be guaranteed by an Eligible Institution.

        6.    Stock Transfer Taxes.    Except as otherwise provided in this Instruction 6, the Purchaser will pay any stock transfer taxes with respect to the transfer and sale of Shares to it or its order in the Offer. If, however, delivery of the consideration is to be made to, or if certificates for Shares not to be tendered or not accepted for payment are to be registered in the name of, any person(s) other than the registered owner(s), or if tendered certificate(s) are registered in the name of any person(s) other than the person(s) signing this Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered owner(s) or such person(s)) payable on account of the transfer to such person(s) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes, or exemption therefrom, is submitted.

        Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificate(s) listed in this Letter of Transmittal.

        7.    Special Payment and Delivery Instructions.    If the purchase price is to be paid to, and/or certificates for Shares not accepted for payment are to be returned to, a person other than the person signing this Letter of Transmittal, or if the check for the purchase price is to be sent and/or such certificates are to be returned to a person other than the person signing this Letter of Transmittal or to an address other than that shown above, the appropriate boxes on this Letter of Transmittal must be completed.

        8.    Waiver of Conditions.    Subject to the terms and conditions of the Merger Agreement (as defined in the Offer to Purchase), the Purchaser reserves the absolute right in its sole discretion to waive any of the conditions (other than the Minimum Condition (as defined in the Offer to Purchase)) of the Offer, in whole or in part, in the case of any Shares to be tendered herewith.

        9.    Backup Withholding.    In order to avoid backup withholding of U.S. federal income tax on payments of cash in the Offer, a stockholder tendering Shares in the Offer who is a U.S. citizen or a U.S. resident alien must, unless an exemption applies, provide the Depositary with such stockholder's correct taxpayer identification number ("TIN") on Substitute Form W-9 included below in this Letter of Transmittal and certify under penalties of



perjury that such TIN is correct and that such stockholder is not subject to backup withholding. If a stockholder does not provide such stockholder's correct TIN or fails to provide the certifications described above, the Internal Revenue Service (the "IRS") may impose a penalty on such stockholder and payment of cash to such stockholder in the Offer may be subject to backup withholding at a rate of 28%.

        Backup withholding is not an additional tax. Rather, the amount of the backup withholding can be credited against the Federal income tax liability of the person subject to the backup withholding, provided that the required information is given to the IRS. If backup withholding results in an overpayment of tax, a refund can be obtained by the stockholder upon filing an income tax return.

        The stockholder is required to give the Depositary the TIN (i.e., social security number or employer identification number) of the record owner(s) of the Shares tendered herewith. If such Shares are held in more than one name, or are not in the name of the actual owner(s), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional guidance on which number to report.

        The box in Part 3 of the Substitute Form W-9 may be checked if the tendering stockholder 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, the stockholder or other payee must also complete the Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that the box in Part 3 is checked and the Certificate of Awaiting Taxpayer Identification Number is completed, the Depositary will withhold 28% on all payments made prior to the time a properly certified TIN is provided to the Depositary. However, such amounts will be refunded to such Stockholder if a TIN is provided to the Depositary within 60 days.

        See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for more instructions.

        Certain stockholders (including, among others, all corporations and certain foreign individuals and entities) are not subject to backup withholding. Tendering stockholders who are not U.S. citizens or U.S. resident aliens should complete and sign the main signature form and a Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding, copies of which may be obtained from the Depositary, in order to avoid backup withholding. Stockholders should consult their tax advisors about qualifying for exemption from backup withholding and the procedure for obtaining such exemption.

        10.    Lost, Destroyed or Stolen Certificates.    If any certificate representing Shares has been lost, destroyed or stolen, the Stockholder should promptly notify the transfer agent for MoSys common stock, Wells Fargo Bank, Minnesota, Shareholder Services, at (800) 468-9716. The stockholder will then be instructed by the transfer agent as to the steps that must be taken in order to replace such certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost or destroyed certificates have been completed.

        IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED FACSIMILE COPY OF IT) TOGETHER WITH ANY SIGNATURE GUARANTEES, OR IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE OF THE OFFER AND EITHER CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER DESCRIBED IN THE OFFER TO PURCHASE, IN EACH CASE ON OR PRIOR TO THE EXPIRATION DATE OF THE OFFER, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY DESCRIBED IN THE OFFER TO PURCHASE.
