                                   COHU, INC.

                    1996 OUTSIDE DIRECTORS STOCK OPTION PLAN
                                  (AS AMENDED)

        1. Purpose. The Cohu, Inc. 1996 Outside Directors Stock Option Plan (the
"Plan") is established effective as of the date the Plan is approved by the
Board of Directors (the "Effective Date") to create additional incentive for the
non-employee directors of Cohu, Inc., a Delaware corporation, and any successor
corporation thereto (collectively referred to as the "Company") to promote the
financial success and progress of the Company and any present or future parent
and/or subsidiary corporations of the Company. For purposes of the Plan, a
parent corporation and a subsidiary corporation shall be as defined in sections
424(e) and 424(f) of the Internal Revenue Code of 1986, as amended (the "Code").

        2. Administration. The Plan shall be administered by the Board of
Directors of the Company (the "Board") and/or by a duly appointed committee of
the Board having such powers as shall be specified by the Board. Any subsequent
references herein to the Board shall also mean the committee if such committee
has been appointed and, unless the powers of the committee have been
specifically limited, the committee shall have all of the powers of the Board
granted herein, including, without limitation, the power to terminate or amend
the Plan at any time, subject to the terms of the Plan and any applicable
limitations imposed by law. The Board shall have no authority, discretion, or
power to select the non-employee directors of the Company who will receive
options under the Plan, to set the exercise price of the options granted under
the Plan, to determine the number of shares of common stock to be granted under
option or the time at which such options are to be granted, to establish the
duration of option grants, or to alter any other terms or conditions specified
in the Plan, except in the sense of administering the Plan subject to the
provisions of the Plan. All questions of interpretation of the Plan or of any
options granted under the Plan (an "Option") shall be determined by the Board,
and such determinations shall be final and binding upon all persons having an
interest in the Plan and/or any Option. Any officer of the Company shall have
the authority to act on behalf of the Company with respect to any matter, right,
obligation, or election which is the responsibility of or which is allocated to
the Company herein, provided the officer has apparent authority with respect to
such matter, right, obligation, or election.

        3. Eligibility and Type of Option. Options may be granted only to
directors of the Company who, at the time of such grant, are not current or
former management employees of the Company or of any parent or subsidiary
corporation of the Company ("Outside Directors"). Options granted to Outside
Directors shall be nonqualified stock options; that is, options which are not
treated as having been granted under section 422(b) of the Code.

        4. Shares Subject to Option. Options shall be for the purchase of shares
of authorized but unissued common stock or treasury shares of common stock of
the Company (the "Stock"), subject to adjustment as provided in paragraph 8
below. The maximum number of shares of Stock which may be issued under the Plan
shall be Three Hundred Thousand (300,000) shares. In the event that any
outstanding Option for any reason expires or is terminated and/or shares of
Stock subject to repurchase are repurchased by the Company, the shares allocable
to the unexercised portion of such Option, or such repurchased shares, may again
be subject to an Option grant. Notwithstanding the foregoing, any such shares
shall be made subject to a new Option only if the grant of such new Option and
the issuance of such shares pursuant to such new

<PAGE>   2

Option would not cause the Plan or any Option granted under the Plan to
contravene Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or any successor rule.

        5. Time for Granting Options. All Options shall be granted, if at all,
within ten years from the Effective Date.

        6. Terms, Conditions and Form of Options. Options granted pursuant to
the Plan shall be evidenced by written agreements specifying the number of
shares of Stock covered thereby, in substantially the form attached hereto as
Exhibit A (the "Option Agreement"), which written agreement may incorporate all
or any of the terms of the Plan by reference and shall comply with and be
subject to the following terms and conditions:

                (a) Automatic Grant of Options. Subject to execution by an
Outside Director of an appropriate Option Agreement, options shall be granted
automatically and without further action of the Board, as follows:

                        9. Each person who is an Outside Director as of the
Effective Date, or who is newly elected or appointed as an Outside Director
after the Effective Date, shall be granted an Option on the Effective Date, or
on the day of such initial election or appointment, as the case may be, to
purchase Ten Thousand (10,000) shares of Stock (the "Initial Grant). On the
first anniversary of the Initial Grant and each successive anniversary, each
Outside Director shall be granted an Option to purchase Five Thousand (5,000)
shares of Stock. Outside Directors who received their Initial Grant more than
one year prior to May 15, 2001 shall be granted an Option to purchase Five
Thousand (5,000) shares of Stock effective May 15, 2001 and on the date of each
successive annual meeting of stockholders held pursuant to Article II, Section 2
of the Company's Bylaws.

                        (ii) Notwithstanding the foregoing, any Outside Director
may elect not to receive an Option granted pursuant to this paragraph 6(a) by
delivering written notice of such election to the Board in the case of an
initial Option grant, no later than the Effective Date or, in the case of an
Outside Director appointed or elected after the Effective Date, the date upon
which such Outside Director is appointed or elected to the Board.

                        (iii) Notwithstanding any other provision of the Plan to
the contrary, no Option shall be granted to any individual on a day when he or
she is no longer serving as an Outside Director of the Company.

                (b) Option Exercise Price. The exercise price per share of Stock
subject to an Option shall be the fair market value of a share of the Stock on
the date of the granting of the Option. Where there is a public market for the
common stock of the Company, the fair market value per share of Stock shall be
the mean of the bid and asked prices of the common stock of the Company on the
business day immediately preceding the date of the granting of the Option, as
reported in the Wall Street Journal (or, if not so reported, as otherwise
reported by the National Association of Securities Dealers Automated Quotation
("NASDAQ") System) or, in the event the common stock of the Company is listed on
the NASDAQ National Market System or a securities exchange, the fair market
value per share of Stock shall be the closing price on such National Market
System or exchange on the business day immediately preceding the date of the
granting of the Option, as reported in the Wall Street Journal. If the common
stock of the



                                        2
<PAGE>   3

Company is not listed on any exchange or quoted on NASDAQ, the Board of
Directors shall in good faith determine the fair market value after
consideration of all relevant factors.

                (c) Exercise Period and Exercisability of Options. An Option
granted pursuant to the Plan shall be exercisable for a term of ten years.
Options granted pursuant to the Plan shall first become exercisable on the day
(the "Initial Vesting Date") which is one year from the date on which the Option
was granted. The Option shall be exercisable on and after the Initial Vesting
Date and prior to termination of the Option in an amount equal to the number of
Option Shares multiplied by the Vested Ratio as set forth below, less the number
of shares previously acquired upon exercise of any portion of the Option.

                                provided the Optionee has continuously
                                served as a director of the Company
                                from the date the Option was granted
                                until the Initial Vesting Date.

               Plus

                        (ii)    For each full year of the                             1/4
                                Optionee's continuous service as a director
                                of the Company from the Initial Vesting Date.
</TABLE>

                (d) Payment of Option Exercise Price. Payment of the exercise
price for the number of shares of Stock being purchased pursuant to any Option
shall be made (i) in cash, by check, or in cash equivalent, (ii) by the
assignment of the proceeds of a sale of some or all of the shares being acquired
upon the exercise of an Option (including, without limitation, through an
exercise complying with the provisions of Regulation T as promulgated from time
to time by the Board of Governors of the Federal Reserve System), (iii) by the
delivery to the Company of shares of Stock which have been owned by the holder
of the Option for more than six months and which have an aggregate value equal
to such exercise price, or (iv) by any combination thereof. The Company
reserves, at any and all times, the right, in the Company's sole and absolute
discretion, to establish, decline to approve and/or terminate any program and/or
procedure for the exercise of Options by means of an assignment of the proceeds
of a sale of some or all of the shares of Stock to be acquired upon such
exercise or the delivery of previously owned shares of Stock.

                (e) Transfer of Control. A "Transfer of Control" shall be deemed
to have occurred in the event any of the following occurs with respect to the
Company:

                        (i) a merger or consolidation where the stockholders of
the Company before such merger or consolidation do not retain, directly or
indirectly, at least a majority of the beneficial interest in the voting stock
of the Company after such merger or consolidation;



                                       3
<PAGE>   4

                        (ii) the sale, exchange, or transfer of all or
substantially all of the assets of the Company other than a sale, exchange, or
transfer to one or more subsidiary corporations (as defined in paragraph 1
above) of the Company; or

                        (iii) the direct or indirect sale or exchange by the
stockholders of the Company of all or substantially all of the stock of the
Company where the stockholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange;

                        (iv) a liquidation or dissolution of the Company.

                        In the event of a proposed Transfer of Control, any
portion of an Option that has not yet become exercisable shall automatically
become exercisable for a period of 30 days prior to the proposed effective date
of the Transfer of Control. In the event of a Transfer of Control, the Board, in
its sole discretion, may arrange with the surviving, continuing, successor, or
purchasing corporation or parent corporation thereof, as the case may be (the
"Acquiring Corporation"), for the Acquiring Corporation to assume the Company's
rights and obligations under outstanding Options or substitute options for the
Acquiring Corporation's stock for such outstanding Options. Any Options which
are neither assumed or substituted for by the Acquiring Corporation nor
exercised as of the date of the Transfer of Control shall terminate and cease to
be outstanding effective as of the date of the Transfer of Control.

        7. Option Agreements; Authority to Vary Terms. Until amended, Options
shall be granted using the form of Option Agreement attached hereto. The Board
shall have the authority from time to time to vary the terms of the Option
Agreements either in connection with the grant of an individual Option or in
connection with the authorization of a new standard form or forms of Option;
provided, however, that the terms and conditions of such revised or amended
standard form or forms of stock option agreement shall be in accordance with the
terms of the Plan. Such authority shall include, but not by way of limitation,
the authority to grant Options which are immediately exercisable subject to the
Company's right to repurchase any unvested shares of Stock acquired by the
Optionee on exercise of an Option in the event such Optionee's service as a
director of the Company is terminated for any reason. In no event shall the
Board be permitted to vary the terms of the Option Agreements or the Plan if
such change would require stockholder approval pursuant to Rule 16b-3
promulgated under the Exchange Act, or any successor rule.

        8. Effect of Change in Stock Subject to Plan. Appropriate adjustments
shall be made in the number and class of shares of Stock subject to the Plan and
to any outstanding Options and in the Option exercise price of any outstanding
Options in the event of a stock dividend, stock split, recapitalization, reverse
stock split, combination, reclassification, or like change in the capital
structure of the Company.

        9. Options Non-Transferable. During the lifetime of an Optionee, an
Option shall be exercisable only by the Optionee. No Option shall be assignable
or transferable by the Optionee, except by will or by the laws of descent and
distribution.

        10. Termination or Amendment of Plan. The Board, including any duly
appointed committee of the Board, may terminate or amend the Plan at any time;
provided, however, that without the approval of the stockholders of the Company,
there shall be (a) no increase in the total number of shares of Stock covered by
the Plan (except by operation of the provisions of paragraph 8 above), and (b)
no expansion in the class of persons eligible to receive Options; and provided,
further, that the provisions of the Plan addressing eligibility to participate
in the Plan and the amount, price and timing of grants of Options shall not be
amended more than once every six months, other than to comport to changes in the
Code, or the rules thereunder. In addition to the foregoing, the approval of the
Company's stockholders shall be sought for any amendment to the Plan for which
the Board deems stockholder approval necessary in order to comply with Rule
16b-3 under the Exchange Act, or any successor rule. In any event, no amendment
may adversely affect any then outstanding Option, or any unexercised portion
thereof, without the consent of the Optionee. This Plan shall be submitted for
stockholder approval at the next annual stockholders' meeting. In the event the
stockholders do not approve the Plan, no further options shall be granted
hereunder.



        IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies
that the foregoing Cohu, Inc. 1996 Outside Directors Stock Option Plan was duly
adopted by the Board of Directors of the Company on November 13, 1996 and

                       NONQUALIFIED STOCK OPTION AGREEMENT
                              FOR OUTSIDE DIRECTORS


        Cohu, Inc., a Delaware corporation (the "Company"), hereby grants to
_____________________________________ (the "Optionee") an option to purchase a

Company (the "Number of Option Shares") under the Cohu, Inc. 1996 Outside
Directors Stock Option Plan (the "Plan"), at an exercise price of $_____ per
share and in the manner and subject to the provisions of this Option Agreement
(the "Option"). The grant, in all respects, is subject to the terms and
conditions of this Option Agreement and the Plan, the provisions of which are
incorporated by reference herein. Unless otherwise provided in this Option
Agreement, capitalized terms shall have the meaning given to such terms in the
Plan. The Number of Option Shares and the exercise price per share of the Option
are subject to adjustment from time to time as provided in the Plan.

        1. Grant of the Option. The Option is granted effective as of
____________________ (the "Date of Option Grant").

        2. Status of the Option. The Option is intended to be a nonqualified
stock option and shall not be treated as an incentive stock option as described
in section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

        3. Term of the Option. The Option shall terminate and may no longer be
exercised on the first to occur of (i) the date ten years after the Date of

                     from the date the Option was

                     service as a director of the
                     Company from the Initial
                     Vesting Date.
</TABLE>


                        (iii) In no event shall the Option be exercisable for
more shares than the Number of Option Shares. In addition to the foregoing, in
the event that the adoption of the Plan or any amendment of the Plan is subject
to the approval of the stockholders of the Company in order for the Option to
comply with the requirements of Rule 16b-3 promulgated under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or any successor rule,
the Option shall not be exercisable in the absence of such stockholder approval.

                (b) Method of Exercise. The Option may be exercised by written
notice to the Company which must state the election to exercise the Option, the
number of shares of stock for which the Option is being exercised and such other
representations and agreements as to the Optionee's investment intent with
respect to such shares as may be required pursuant to the provisions of this
Option Agreement and the Plan. The written notice must be signed by the Optionee
and must be delivered in person or by certified or registered mail, return
receipt requested, to the Chief Financial Officer of the Company, or other
authorized representative of the Company, prior to the termination of the Option
as set forth in paragraph 3 above, accompanied by full payment of the exercise
price for the number of shares of Stock being purchased in a form permitted
under the terms of the Plan.

                (c) Withholding. At the time the Option is exercised, in whole
or in part, or at any time thereafter as requested by the Company, the Optionee
shall make adequate provision for the foreign, federal and state tax withholding
obligations of the Company, if any, which arise in connection with the Option
including, without limitation, obligations arising upon (i) the exercise, in
whole or in part, of the Option, (ii) the transfer, in whole or in part, of any
shares of stock acquired on exercise of the Option, or (iii) the lapsing of any
restriction with respect to any shares acquired on exercise of the Option.



                                       7
<PAGE>   8

                (d) Certificate Registration. The certificate or certificates
for the shares of stock as to which the Option shall be exercised shall be
registered in the name of the Optionee, or, if applicable, the heirs of the
Optionee.

                (e) Restriction on Grant of the Option and Issuance of Shares.
The grant of the Option and the issuance of shares of stock on exercise of the
Option shall be subject to compliance with all of the applicable requirements of
federal or state law with respect to such securities. The Option may not be
exercised if the issuance of shares of stock upon such exercise would constitute
a violation of any applicable federal or state securities laws or other law or
regulation. In addition, no Option may be exercised unless (i) a registration
statement under the Securities Act of 1933, as amended (the "Securities Act"),
shall at the time of exercise of the Option be in effect with respect to the
shares of stock issuable upon exercise of the Option, or (ii) in the opinion of
legal counsel to the Company, the shares issuable upon exercise of the Option
may be issued in accordance with the terms of an applicable exemption from the
registration requirements of the Securities Act. As a condition to the exercise
of the Option, the Company may require the Optionee to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation and to make any representation or warranty with
respect thereto as may be requested by the Company.

                (f) Fractional Shares. The Company shall not be required to
issue fractional shares of stock upon the exercise of the Option.

        5. Non-Transferability of the Option. The Option may be exercised during
the lifetime of the Optionee only by the Optionee and may not be assigned or
transferred in any manner except by will or by the laws of descent and
distribution.

        6. Termination of Service as a Director.

                (a) Termination of Director Status. If the Optionee ceases to be
a director of the Company for any reason except death or disability within the
meaning of section 22(e)(3) of the Code, the Option, to the extent unexercised
and exercisable by the Optionee on the date on which the Optionee ceased to be a
director, may be exercised by the Optionee at any time prior to the expiration
of three months from the date on which the Optionee's service as a director of
the Company terminated, but in any event no later than the Option Termination
Date. If the Optionee ceases to be a director of the Company because of the
death or disability of the Optionee within the meaning of section 22(e)(3) of
the Code, the Option, to the extent unexercised and exercisable by the Optionee
on the date on which the Optionee ceased to be a director, may be exercised by
the Optionee (or the Optionee's legal representative) at any time prior to the
expiration of six months from the date on which the Optionee's service as a
director of the Company terminated, but in any event no later than the Option
Termination Date. The Optionee's service as a director of the Company shall be
deemed to have terminated on account of death if the Optionee dies within three
months after the Optionee's termination of service as a director of the Company.
Except as provided in this paragraph 6, an Option shall terminate and may not be
exercised after the Optionee ceases to be a director of the Company.

                (b) Extension of Exercise Prevented by Law. Notwithstanding the
foregoing, if the exercise of the Option within the applicable time periods set
forth above is prevented because the issuance of shares of stock upon such
exercise would constitute a violation of any applicable federal or state
securities law or other law or regulation, the Option shall remain



                                       8
<PAGE>   9

exercisable until three months after the date the Optionee is notified by the
Company that the Option is exercisable, but in any event no later than the
Option Termination Date.

                (c) Extension if Optionee Subject to Section 16(b).
Notwithstanding the foregoing, if the exercise of the Option within the
applicable time periods set forth above would subject the Optionee to suit under
Section 16(b) of the Exchange Act, the Option shall remain exercisable until the
earliest to occur of (i) the tenth (10th) day following the date on which the
Optionee would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after the Optionee's termination of service as a director
of the Company and (iii) the Option Termination Date.

        7. Rights as a Stockholder; Rights to Serve as a Director. The Optionee
shall have no rights as a stockholder with respect to any shares of stock
covered by the Option until the date of the issuance of a certificate or
certificates for the shares for which the Option has been exercised. No
adjustment shall be made for dividends or distributions or other rights for
which the record date is prior to the date such stock certificate or
certificates are issued, except as provided in the Plan. Nothing herein shall be
deemed to provide the Optionee with any right to serve as a director of the
Company for any length of time.

        8. Effect of Change in Stock Subject to the Option. Appropriate
adjustments shall be made in the number, exercise price and class of shares of
stock subject to the Option in the event of a stock dividend, stock split,
reverse stock split, recapitalization, combination, reclassification, or like
change in the capital structure of the Company. In the event a majority of the
shares which are of the same class as the shares that are subject to the Option
are exchanged for, converted into, or otherwise become shares of another
corporation (the "New Shares"), the Company may unilaterally amend the Option to
provide that the Option is exercisable for New Shares. In the event of any such
amendment, the number of shares and the exercise price shall be adjusted in a
fair and equitable manner.

        9. Transfer of Control. A "Transfer of Control" shall be deemed to have
occurred in the event any of the following occurs with respect to the Company:

                (a) a merger or consolidation where the stockholders of the
Company before such merger or consolidation do not retain, directly or
indirectly, at least a majority of the beneficial interest in the voting stock
of the Company after such merger or consolidation;

                (b) the sale, exchange, or transfer of all or substantially all
of the assets of the Company (other than a sale, exchange, or transfer to one or
more subsidiary corporations (as defined in the Plan) of the Company);

                (c) the direct or indirect sale or exchange by the stockholders
of the Company of all or substantially all of the stock of the Company where the
stockholders of the Company before such sale or exchange do not retain, directly
or indirectly, at least a majority of the beneficial interest in the voting
stock of the Company after such sale or exchange; or

                (d) A liquidation or dissolution of the Company.

                In the event of a proposed Transfer of Control, any portion of
this Option that has not yet become exercisable shall automatically become
exercisable for a period of 30 days prior to the proposed effective date of such
Transfer of Control. In the event of a Transfer of Control, the Board, in its
sole discretion, may arrange with the surviving, continuing, successor, or
purchasing corporation or parent corporation thereof, as the case may be (the
"Acquiring Corporation"), for the Acquiring Corporation to assume the Company's
rights and obligations under the Option or substitute options for the Acquiring
Corporation's stock for the Option. To the extent the Option is neither assumed
or substituted for by the Acquiring Corporation in connection with the Transfer
of Control nor exercised as of the date of the Transfer of Control, the Option
shall terminate and cease to be outstanding effective as of the date of the
Transfer of Control.

        10. Legends. The Company may at any time place legends referencing any
applicable federal or state securities law restrictions on all certificates
representing shares of stock subject to the provisions of this Option Agreement.
The Optionee shall, at the request of the Company, promptly present to the
Company any and all certificates representing shares of stock acquired pursuant
to the Option in the possession of the Optionee in order to effectuate the
provisions of this paragraph.

        11. Binding Effect. This Option Agreement shall inure to the benefit of
the successors and assigns of the Company and be binding upon the Company and
the Optionee and the Optionee's heirs, executors, administrators, successors and
assigns.

        12. Termination or Amendment. The Board, including any duly appointed
committee of the Board, may terminate or amend the Plan and/or the Option at any
time subject to any limitations described in the Plan; provided, however, that
no such termination or amendment may adversely affect the Option or any
unexercised portion hereof without the consent of the Optionee.

        13. Integrated Agreement. This Option Agreement and the Plan constitute
the entire understanding and agreement of the Optionee and the Company with
respect to the subject matter contained herein and therein, and there are no
agreements, understandings, restrictions, representations, or warranties among
the Optionee and the Company other than those as set forth or provided for
herein or therein. To the extent contemplated herein and therein, the provisions
of this Option Agreement and the Plan shall survive any exercise of the Option
and shall remain in full force and effect.
