                            OPTION ROLLOVER AGREEMENT
                                (U.S. EMPLOYEES)

         OPTION ROLLOVER AGREEMENT dated as of January 23, 2004 (the
"Agreement") between CPI Acquisition Corp., a Delaware corporation, (the
"Acquiror"), and the manager named on Schedule A (the "Manager").

         WHEREAS, the Acquiror, CPI Merger Sub Corp. (the "Merger Sub"),
Communications & Power Industries Holding Corporation (the "Company") and Green
Equity Investors II, L.P. have entered into an Agreement and Plan of Merger,
dated as of November 17, 2003 (the "Merger Agreement");

         WHEREAS, pursuant to the Merger Agreement, as of the Closing which
occurs on the Closing Date (each as defined in the Merger Agreement), the Merger
Sub will merge with and into the Company, with the Company surviving, and the
Company shall be a wholly owned subsidiary of the Acquiror; and

         WHEREAS, the Manager and other members of the Company management team
currently hold options to acquire shares of the Company's common stock ("Company
Options") and have agreed that, as of the Closing Date, Company Options shall be
converted into options to purchase shares of the Acquiror;

         NOW THEREFORE, in consideration of the foregoing, and the covenants and
promises and representations set forth herein, and for other good and valuable
consideration the receipt and sufficiency of which is hereby acknowledged and
accepted, the parties hereto agree as follows:

                  1.       This Agreement shall constitute a binding obligation
of the parties hereto as of the date hereof; provided that the operative
provisions of this Agreement shall only take effect upon the occurrence of the
Closing Date. In the event the Merger Agreement is terminated for any reason
without the Closing Date having occurred, this Agreement shall be terminated
without further obligation or liability of any party hereunder. Defined terms
not otherwise defined herein shall have the meanings set forth in the Merger
Agreement.

                  2.       Notwithstanding any provision in the Merger
Agreement, as of the date hereof, the Manager agrees not to exercise any Company
Options.

                  3.       With respect to each grant of Company Options held by
the Manager as of the Closing Date, the Manager agrees that the number of
Company Options subject to such grant set forth on Schedule A attached hereto
(the "Continuing Options") shall be converted into options to purchase shares of
the Acquiror ("Acquiror Options"). The remaining Company Options shall be
cancelled and shall be converted into the right to receive a cash payment as set
forth in the Merger Agreement. Each Acquiror Option shall be subject to the same
terms and conditions as the corresponding Company Option (provided that the
vesting of such Acquiror Option shall accelerate to the extent that the vesting
of the corresponding Company Option accelerates pursuant to the Merger
Agreement) and, in the aggregate, shall, as of immediately

                                                                               2

following the Closing Date, preserve the difference between (a) the Per Share
Amount minus (b) the exercise price per share of such Company Option. The shares
of Acquiror issued upon exercise of the Acquiror Options will be subject to the
terms and conditions of the stockholders' agreement described in the Information
Memorandum previously provided to the Manager. In addition, with respect to each
Continuing Option, the Manager shall be entitled to (x) the Per Share Additional
Amount (if any) and (y) the payment described in Section 2.3.1(e) of the Merger
Agreement and distributions from the Expense Escrow Amount and the Working
Capital Escrow Amount, subject to the terms and conditions of the Merger
Agreement and the Escrow Agreement, such amounts payable in accordance with the
Merger Agreement.

                  4.       The Manager represents and warrants to the Acquiror
as follows:

                           (a)      The Manager is as of the date hereof an
employee of the Company and in such capacity has acquired at least a general
understanding of the Company and its business. The Manager has been given the
opportunity to obtain any additional information or documents (and to ask
questions and receive answers about such information and documents) about the
Acquiror and its business (and the Company and its business) which he deems
necessary to evaluate the merits and risks related to his investment in the
Acquiror Options (which, for purposes of this Section 4 shall include the
underlying shares of the Acquiror).

                           (b)      In making his decision to invest in the
Acquiror, the Manager has relied upon independent investigations made by him
and, to the extent believed by the Manager to be appropriate, his
representatives, including his own professional, financial, tax and other
advisors.

                           (c)      The Manager is able to bear the economic
risk of a total loss of the Manager's investment in the Acquiror, and the
Manager has adequate means of providing for the Manager's current needs and
foreseeable personal contingencies and has no need for the Manager's investment
in the Acquiror Options to be liquid.

                           (d)      The Manager understands that an investment
in the Acquiror is a speculative investment which involves a high degree of risk
of loss of his investment therein, there are substantial restrictions on the
transferability of the Acquiror Options, and, on the date hereof and for an
indefinite period following the date hereof, there will be no public market for
the Acquiror Options and, accordingly, it may not be possible for the Manager to
liquidate his investment in case of emergency, if at all.

                           (e)      The Manager understands and has taken
cognizance of all risk factors related to the retention of the Acquiror Options,
and the Manager has such knowledge and experience in financial and business
matters that he is capable of evaluating the merits and risks of his purchase of
the Acquiror Options as contemplated by this Agreement.

                  5.       This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

                  6.       This Agreement may be executed in counterparts, all
of which shall be considered one and the same agreement, it being understood
that all parties need not sign the same counterpart.
