                     MEMORANDUM OF UNDERSTANDING RELATING TO
                 COMMON STOCK ISSUANCE AND RELATED TRANSACTIONS

                                  MAY 10, 2001

        This Memorandum of Understanding Relating to Common Stock Issuance and
Related Transactions (the "MOU") is entered into as of May 10, 2001 by and
between IMP, Inc., a Delaware corporation ("IMP"), and Subba Rao Pinamaneni on
behalf of himself and an investment group to be formed by him including K.Y.
Mok, Dilip Kumor V. Lakhi, John Chu, Sugriva Reddy, Tarsaim Batra and Moiz
Khambaty (the "New Investor").

        The background of this MOU is that IMP presently requires a significant
cash infusion in order to avoid an insolvency that would require a filing for
protection under applicable bankruptcy laws. Cash infusions have been sought
from multiple parties, including the existing majority stockholder and its
affiliates, but no viable offer has been obtained. In order to avoid the
insolvency of IMP, IMP and the New Investor have reached an agreement on the
material terms of a cash infusion from the New Investor upon the terms and
subject to the conditions set forth in this MOU. The terms of this transaction
have been approved by the Board of Directors of IMP, including the independent
director, and the majority stockholder. These terms are set forth below:

TRANSACTION SUMMARY:    IMP will issue and sell to the New Investor, and the
                        New Investor will purchase from IMP, shares of IMP's
                        common stock representing 75% of IMP's fully diluted
                        equity after giving effect to such issuance. The
                        calculation of IMP's fully diluted capitalization will
                        include the following: (1) all outstanding shares of
                        common stock and (2) all shares issuable upon exercise
                        of warrants outstanding on the date of this MOU. The
                        calculation will exclude any shares issuable upon (a)
                        exercise of outstanding stock options to purchase shares
                        of common stock, (b) conversion of outstanding
                        convertible debentures held by Teamasia Semiconductors
                        (India) Ltd. ("TSIL" and, collectively with its
                        affiliates, "Teamasia") and (c) exercise of warrants to
                        be issued to TSIL. The estimated capitalization of IMP
                        is set forth on Exhibit A hereto.

PURCHASE PRICE:         The New Investor will pay a purchase price equal to $6.0
                        million in cash and/or through the issuance of one or
                        more irrevocable letters of credit by a reputable bank
                        for the benefit of IMP. The New Investor will provide
                        reasonable assurances to IMP of the New Investor's
                        ability to meet its funding obligations. All payments
                        made to IMP by the New Investor after 8:00 a.m. on
                        Monday, May 7, 2001 shall be deemed to be advances
                        towards, and shall count against, the $6.0 million
                        purchase price. The New Investor shall provide the

                            Company with an accounting (including reasonable
                            backup documentation) of any and all amounts to be
                            applied toward such purchase price.

                            The payment of the purchase price by the New
                            Investor will be structured so as to assure that
                            IMP's material short-term cash requirements are met.
                            At a minimum, the $6.0 million will be funded as
                            follows: $2.6 million will be available on or before
                            June 8, 2001 and $3.4 million will be available on
                            or before July 9, 2001. No later than May 24, 2001,
                            the New Investor will provide IMP's Board of
                            Directors with written confirmation that IMP has
                            paid all amounts then due or owing with regard to
                            payroll expenses, rent, insurance premiums, health
                            plan premiums and statutory payments set forth on
                            Exhibit B hereto.

ISSUANCE OF SHARES:         Upon the funding by the New Investor of a minimum of
                            $2.75 million of the purchase price, IMP shall issue
                            to the New Investor an aggregate of one-third of the
                            total shares to be issued to the New Investor. Upon
                            the funding by the New Investor of the $3.25 million
                            balance of the purchase price, IMP shall issue to
                            the New Investor the remaining two-thirds of the
                            total shares to be issued to the New Investor.

TREATMENT OF INDEBTEDNESS:  To date, the New Investor has provided short-term
                            bridge financing in an aggregate amount of
                            approximately $1.4 million (the "Management
                            Advances"). The Management Advances shall not count
                            towards the $6.0 million purchase price to be paid
                            by the New Investor and shall remain an unsecured
                            obligation of IMP to the New Investor.

TERMINATION RIGHT:          For a period of 30 days after the definitive terms
                            of the investment to be made by the New Investor
                            pursuant to this MOU is made public by a filing on
                            Form 8-K with the Securities and Exchange
                            Commission, IMP shall have the right to terminate
                            the transactions between it and the New Investor
                            described in this MOU in the event that IMP receives
                            an unsolicited offer (a "Competing Offer") from a
                            third party (other than HSBC (except in connection
                            with a co-investment by a third party with
                            semiconductor industry expertise), TSIL, Linfinity
                            Microelectronics or their respective affiliates,
                            each of which has previously indicated that it is
                            unwilling to make such an investment) with respect
                            to a transaction which the Board of Directors of IMP
                            determines to be a superior transaction for the
                            stockholders of IMP to the transaction described in
                            this MOU; provided, however, that in the event that
                            the Company receives a Competing Offer, the Company
                            will afford the New Investor the

                            consideration by IMP's Board of Directors which
                            matches the terms of the Competing Offer.

EFFECT OF TERMINATION:      In the event that IMP exercises its termination
                            right, IMP will (1) redeem all securities previously
                            issued to the New Investor in accordance with this
                            MOU as well as the Management Advances for a cash
                            payment equal to the original cost of such
                            investments, and (2) make a cash payment to the New
                            Investor in an amount equal to the New Investor's
                            reasonable documented out of pocket expenses, plus
                            $500,000.

NO ACTIVE SOLICITATION:     IMP will not actively seek a Competing Offer, but
                            shall be free, in the exercise of the fiduciary
                            duties of the Board of Directors, to pursue any
                            inquiries received. All inquiries received by
                            management or any director shall promptly be
                            communicated to the full Board of Directors.

REGISTRATION RIGHTS:        IMP will grant to the New Investor customary demand
                            and piggyback registration rights.

APPROVALS:                  These transactions have been approved by the Board
                            of Directors of IMP, such approval consisting of the
                            unanimous approval of the independent director and,
                            based on that recommendation, the unanimous approval
                            of all directors. Such further corporate approvals
                            as deemed appropriate by IMP and the New Investor
                            will be sought and obtained.

CONFIDENTIALITY:            Unless otherwise required by law or legal process,
                            IMP and the New Investor will maintain the
                            confidentiality of the proposed transaction until
                            the parties mutually agree to issue a press release.
                            Notwithstanding the foregoing, the parties will
                            cooperate fully in the continued compliance by IMP
                            with its obligations under the United States federal
                            securities laws.
