                             STOCK OPTION AGREEMENT
                                   (DIRECTORS)

     THIS STOCK OPTION AGREEMENT (the "AGREEMENT") is made and entered into as
of the date of grant set forth on Exhibit A hereto by and between CPI
International, Inc., a Delaware corporation (the "COMPANY"), and the individual
(the "OPTIONEE") set forth on Exhibit A.

     A. Optionee is becoming a member of the Board of Directors of the Company
("BOARD").

     B. The Board has determined that it is appropriate, desirable and in the
best interests of the Company to grant options to Optionee.

     C. Accordingly, pursuant to the CPI International, Inc. 2006 Equity and
Performance Incentive Plan (the "PLAN"), the Company is hereby issuing this
option (the "OPTION") to purchase the number of shares of the Common Stock of
the Company (the "SHARES" or the "OPTION SHARES") set forth on Exhibit A hereto,
at the exercise price determined as provided herein, and in all respects subject
to the terms, definitions and provisions of the Plan, which is incorporated
herein by reference.

     D. Unless otherwise defined herein, capitalized terms used in this
Agreement shall have the meanings set forth in the Plan.

     NOW, THEREFORE, in consideration of the mutual agreements contained herein,
the Optionee and the Company hereby agree as follows:

1.   Grant and Terms of Stock Option.

     1.1 Grant of Option. The Company has granted to the Optionee the right and
option to purchase, subject to the terms and conditions set forth in the Plan
and this Agreement, all or any part of the number of Shares set forth on Exhibit
A at a purchase price per Share equal to the exercise price per Share set forth
on Exhibit A. This Option is not intended to be an Incentive Stock Option and is
instead intended to be a Nonqualified Stock Option.

     1.2 Vesting and Exercisability. Subject to the provisions of the Plan and
the other provisions of this Agreement, this Option shall vest and become
exercisable in accordance with the schedule set forth on Exhibit A.
Notwithstanding the foregoing, in the event of termination of Optionee's status
as a director for any reason, this Option shall immediately cease vesting;
provided, however, if such termination occurs as a result of either death or
Disability, the vesting of this Option shall be partially accelerated as set
forth on Exhibit A hereto.


                                       -1-



     1.3 Term of Option. The "TERM" of this Option shall begin on the date of
grant set forth on Exhibit A and end on the expiration of the Term specified on
Exhibit A. No portion of this Option may be exercised after the expiration of
the Term.

          1.3.1 In the event of termination of Optionee's status as a director
     as a result of death or Disability, this Option shall terminate and be
     cancelled on the earlier of (i) the expiration of the Term, or (ii) 12
     months after termination of Optionee's status as a director.

          1.3.2 In the event of termination of Optionee's status as a director
     for any reason other than cause, death or Disability, the portion of this
     Option that is not vested and exercisable as of the date of termination
     shall be immediately cancelled and terminated. In addition, the portion of
     this Option that is vested and exercisable as of the date of termination of
     Optionee's status as a director shall terminate and be cancelled on the
     earlier of (i) the expiration of the Term, or (ii) the Exercise Termination
     Date. The "Exercise Termination Date" shall mean the later of (x) 90 days
     after termination of Optionee's status as a director or (y) if Optionee
     reasonably determines that Optionee is prohibited or restricted from
     selling Shares in the public markets for any portion of the 90 day period
     in clause (x) (whether as a result of the possession of information that
     might be considered material nonpublic information, the absence of a
     registration statement available to Optionee, or other legal or contractual
     restrictions on sale), 90 days after all such restrictions cease to exist.

          1.3.3 If Optionee's status as a director is terminated for cause, this
     entire Option shall be cancelled and terminated as of the date of such
     termination and shall no longer be exercisable as to any Shares, whether or
     not previously vested.

2.   Method of Exercise.

     2.1 Delivery of Notice of Exercise. This Option shall be exercisable by
written notice in the form attached hereto as Exhibit B which shall state the
election to exercise this Option, the number of Shares in respect of which this
Option is being exercised, and such other representations and agreements with
respect to such Shares as may be required by the Company pursuant to the
provisions of this Agreement and the Plan. Such written notice shall be signed
by Optionee (or by Optionee's beneficiary or other person entitled to exercise
this Option in the event of Optionee's death under the Plan) and shall be
delivered in person or by overnight delivery service or certified mail to the
Secretary of the Company. At the same time, the Optionee shall pay the exercise
price to the Company. This Option shall not be deemed exercised until the
Company receives such written notice and the exercise price and any other
applicable terms and conditions of this Agreement are satisfied. This Option may
not be exercised for a fraction of a Share.

     2.2 Restrictions on Exercise. No Shares will be issued pursuant to the
exercise of this Option unless and until there shall have been full compliance
with all applicable requirements of the Securities Act of 1933, as amended
(whether by registration or satisfaction of exemption conditions), all
Applicable Laws, and all applicable listing requirements of any national
securities exchange or other market system on which the Common Stock is then
listed. As a condition to the exercise of this Option, the Company


                                       -2-



may require Optionee to make any representation and warranty to the Company as
may be necessary or appropriate, in the judgment of the Committee, to comply
with any Applicable Law.

     2.3 Method of Payment. Payment of the exercise price shall be made in full
at the time of exercise (a) in cash or by certified check or bank check or wire
transfer of immediately available funds, (b) by delivery of a properly executed
exercise notice together with any other documentation as the Committee and the
Participant's broker, if applicable, require to effect an exercise of the Option
and delivery to the Company of the sale or other proceeds (as permitted by
Applicable Law) required to pay the exercise price, or (c) with the consent of
the Committee in its discretion, by tendering previously acquired Shares (either
actually or by attestation, valued at their then Fair Market Value) that have
been owned for a period of at least six months (or such other period to avoid
accounting charges against the Company's earnings). In addition, the Committee
may impose such other conditions in connection with the delivery of shares of
Common Stock in satisfaction of the exercise price as it deems appropriate in
its sole discretion.

     2.4 Tax Withholding Obligations. In addition to the foregoing requirements,
any exercise of this Option shall be conditioned upon the Optionee satisfying
any applicable tax withholding obligations imposed on the Company in connection
with the exercise of this Option.

3. Non-Transferability of Option. This Option may not be transferred in any
manner otherwise than by will or by the laws of descent or distribution or to a
beneficiary designated pursuant to the Plan, and may be exercised during the
lifetime of Optionee only by Optionee. Subject to all of the other terms and
conditions of this Agreement, following the death of Optionee, this Option may,
to the extent it is vested and exercisable by Optionee in accordance with its
terms on the date of death, be exercised by Optionee's beneficiary or other
person entitled to exercise this Option in the event of Optionee's death under
the Plan. This Option may be assigned, in connection with the Optionee's estate
plan, in whole or in part, during the Optionee's lifetime to one or more Family
Members of the Optionee. Rights under the assigned portion may be exercised by
the person or persons who acquire a proprietary interest in such Option pursuant
to the assignment. The terms applicable to the assigned portion shall be the
same as those in effect for the Option immediately before such assignment and
shall be set forth in such documents issued to the assignee as the Committee
deems appropriate.

4. Restrictions; Restrictive Legends. Ownership and transfer of Shares issued
pursuant to the exercise of this Option will be subject to the provisions of,
including ownership and transfer restrictions (including, without limitation,
restrictions imposed by Applicable Laws and restrictions set forth or referenced
in legends imprinted on certificates representing such Shares).

remedies it may have at law or under this Agreement.
