                               GENERAL PROVISIONS


      I.    PURPOSE OF THE PLAN

            This 1995 Stock Option Plan is intended to promote the interests of
Phase Metrics, Inc., a California corporation, by providing eligible persons
with the opportunity to acquire a proprietary interest, or otherwise increase
their proprietary interest, in the Corporation as an incentive for them to
remain in the service of the Corporation.

            Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

      II.   ADMINISTRATION OF THE PLAN

            A.    The Plan shall be administered by the Board. However, any or
all administrative functions otherwise exercisable by the Board may be delegated
to the Committee. Members of the Committee shall serve for such period of time
as the Board may determine and shall be subject to removal by the Board at any
time. The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

            B.    The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest in
the Plan or any option or shares issued thereunder.

      III.  ELIGIBILITY

            A.    The persons eligible to receive option grants under the Plan
are as follows:

                        (i)   Employees,


   2
                        (ii)  non-employee members of the Board or the
      non-employee members of the board of directors of any Parent or
      Subsidiary, and

                        (iii) consultants who provide services to the
      Corporation (or any Parent or Subsidiary).

            B.    The Plan Administrator shall have full authority to determine
which eligible persons are to receive option grants under the Plan, the time or
times when such option grants are to be made, the number of shares to be covered
by each such grant, the status of the granted option as either an Incentive
Option or a Non-Statutory Option, the time or times at which each option is to
become exercisable, the vesting schedule (if any) applicable to the option
shares and the maximum term for which the option is to remain outstanding.

      IV.   STOCK SUBJECT TO THE PLAN

            A.    The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
4,050,000(1)(2)(3)(4) shares.

            B.    Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two. All shares issued under the Plan, whether or not those shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan, shall reduce on a share-for-share basis the number of shares of
Common Stock available for subsequent issuance under the Plan.

            C.    Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of

Board on November 28, 1995. Also includes the 150,000-share (pre-split) increase
approved by the Board on July 24, 1996. The additional 150,000-share (pre-split)
contingent increase approved by the Board on July 24, 1996 is not included

consideration, appropriate adjustments shall be made to (i) the maximum number
and/or class of securities issuable under the Plan and (ii) the number and/or
class of securities and the exercise price per share in effect under each
outstanding option in order to prevent the dilution or enlargement of benefits
thereunder. The adjustments determined by the Plan Administrator shall be final,
binding and conclusive. In no event shall any such adjustments be made in
connection with the conversion of one or more outstanding shares of the
Corporation's preferred stock into shares of Common Stock.

                                   ARTICLE TWO

                              OPTION GRANT PROGRAM


      I.    OPTION TERMS

            Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

            A.    EXERCISE PRICE.

                  1.    The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                        (i)   The exercise price per share shall not be less
      than eighty-five percent (85%) of the Fair Market Value per share of
      Common Stock on the option grant date.

                        (ii)  If the person to whom the option is granted is a
      10% Shareholder, then the exercise price per share shall not be less than
      one hundred ten percent (110%) of the Fair Market Value per share of
      Common Stock on the option grant date.

                  2.    The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Three and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12(g) of the 1934 Act at the time the option is exercised, then
the exercise price may also be paid as follows:

                        (i)   in shares of Common Stock held for the requisite
      period necessary to avoid a charge to the Corporation's earnings for
      financial reporting purposes and valued at Fair Market Value on the
      Exercise Date, or


                                       3.
   4
                        (ii)  to the extent the option is exercised for vested
      shares, through a special sale and remittance procedure pursuant to which
      the Optionee shall concurrently provide irrevocable written instructions
      (a) to a Corporation-designated brokerage firm to effect the immediate
      sale of the purchased shares and remit to the Corporation, out of the sale
      proceeds available on the settlement date, sufficient funds to cover the
      aggregate exercise price payable for the purchased shares plus all
      applicable Federal, state and local income and employment taxes required
      to be withheld by the Corporation by reason of such exercise and (b) to
      the Corporation to deliver the certificates for the purchased shares
      directly to such brokerage firm in order to complete the sale.

            Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

            B.    EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option grant. However, no option shall have a term in excess of
ten (10) years measured from the option grant date.

            C.    EFFECT OF TERMINATION OF SERVICE. The following provisions
shall govern the exercise of any options held by the Optionee at the time of
cessation of Service or death:

                        (i)   Should the Optionee cease to remain in Service for
      any reason other than Disability or death, then the Optionee shall have a
      period of three (3) months following the date of such cessation of Service
      during which to exercise each outstanding option held by such Optionee.

                        (ii)  Should such Service terminate by reason of
      Disability, then the Optionee shall have a period of six (6) months
      following the date of such cessation of Service during which to exercise
      each outstanding option held by such Optionee. However, should such
      Disability be deemed to constitute Permanent Disability, then the period
      during which each outstanding option held by the Optionee is to remain
      exercisable shall be extended by an additional six (6) months so that the
      exercise period shall be the twelve (12)- month period following the date
      of the Optionee's cessation of Service by reason of such Permanent
      Disability.

                        (iii) Should the Optionee die while holding one or more
      outstanding options, then the personal representative of the Optionee's
      estate or the person or persons to whom the option is transferred pursuant
      to the Optionee's will or in accordance with the laws of descent and
      distribution shall


                                       4.
   5
      have a period of twelve (12) months following the date of the Optionee's
      death during which to exercise each such option.

                        (iv)  Under no circumstances, however, shall any such
      option be exercisable after the specified expiration of the option term.

                        (v)   During the applicable post-Service exercise
      period, the option may not be exercised in the aggregate for more than the
      number of vested shares for which the option is exercisable on the date of
      the Optionee's cessation of Service. However, should the Optionee's
      Service terminate by reason of his or her death, then all of the shares
      subject to each outstanding option held by the Optionee at the time of
      death shall immediately vest, and each option may be exercised for any or
      all of those vested shares at any time during the applicable post-Service
      exercise period.

                        (vi)  Upon the expiration of the applicable post-Service
      exercise period or (if earlier) upon the expiration of the option term,
      the option shall terminate and cease to be outstanding for any vested
      shares for which the option has not been exercised. However, the option
      shall, immediately upon the Optionee's cessation of Service, terminate and
      cease to be outstanding to the extent it is not exercisable for vested
      shares on the date of such cessation of Service.

            D.    SHAREHOLDER RIGHTS. The holder of an option shall have no
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

            E.    UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock under the Plan. Should the Optionee cease Service while holding such
unvested shares, the Corporation shall have the right to repurchase, at the
exercise price paid per share, all or (at the discretion of the Corporation and
with the consent of the Optionee) any of those unvested shares. The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right. The Plan Administrator may not impose
a vesting schedule upon any option grant or any shares of Common Stock subject
to the option which is more restrictive than twenty percent (20%) per year
vesting, beginning one (1) year after the option grant date.

            F.    FIRST REFUSAL RIGHTS. Until such time as the Common Stock is
first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be


                                       5.
   6
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

            G.    LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death. However, a Non-Statutory Option may
be assigned in accordance with the terms of a Qualified Domestic Relations
Order. The assigned option may only be exercised by the person or persons who
acquire a proprietary interest in the option pursuant to such Qualified Domestic
Relations Order. The terms applicable to the assigned option (or portion
thereof) shall be the same as those in effect for the option immediately prior
to such assignment and shall be set forth in such documents issued to the
assignee as the Plan Administrator may deem appropriate.

            H.    WITHHOLDING. The Corporation's obligation to deliver shares of
Common Stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

      II.   INCENTIVE OPTIONS

            The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options. Options which
are specifically designated as Non-Statutory Options shall not be subject to the
terms specified in this Section II.

            A.    ELIGIBILITY. Incentive Options may only be granted to
Employees.

            B.    EXERCISE PRICE. The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

            C.    DOLLAR LIMITATION. The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

            D.    10% SHAREHOLDER. If any Employee to whom an Incentive Option
is granted is a 10% Shareholder, then the option term shall not exceed five (5)
years measured from the option grant date.


                                       6.
   7
      III.  CORPORATE TRANSACTION

            A.    In the event of any Corporate Transaction, each outstanding
option shall terminate and cease to be outstanding, except to the extent assumed
by the successor corporation (or parent thereof) in connection with such
Corporate Transaction. In addition, all outstanding repurchase rights under the
Plan shall terminate in the event of any Corporate Transaction, except to the
extent the repurchase rights are assigned to the successor corporation (or
parent thereof) in connection with such Corporate Transaction.

            B.    Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in the consummation of such Corporate Transaction,
had the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same.

            C.    The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

      IV.   CANCELLATION AND REGRANT OF OPTIONS

            The Plan Administrator shall have the authority to effect, at any
time and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                  MISCELLANEOUS


      I.    FINANCING

            The Plan Administrator may permit any Optionee to pay the option
exercise price by delivering a promissory note payable in one or more
installments. The terms of any such promissory note (including the interest rate
and the terms of repayment) shall be established by the Plan Administrator in
its sole discretion. Promissory notes may be authorized with or without security
or collateral. However, any promissory notes delivered by a consultant must be
secured by property other than the purchased shares of Common Stock. In all
events, the maximum credit available to each Optionee may not exceed the sum of
(i) the aggregate option exercise price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee in connection with the option exercise.

      II.   ADDITIONAL AUTHORITY

            A.    The Plan Administrator shall have the discretion, exercisable
either at the time an option is granted or at any time while the option remains
outstanding:

                        (i)   to extend the period of time for which the option
      is to remain exercisable following the Optionee's cessation of Service or
      death from the limited period otherwise in effect for that option to such
      greater period of time as the Plan Administrator shall deem appropriate;
      provided, that in no event shall such option be exercisable after the
      specified expiration of the option term, and/or

                        (ii)  to permit the option to be exercised, during the
      applicable post-Service exercise period, not only with respect to the
      number of vested shares of Common Stock for which such option is
      exercisable at the time of the Optionee's cessation of Service or death
      but also with respect to one or more additional installments in which the
      Optionee would have vested under the option had the Optionee continued in
      Service.

      III.  EFFECTIVE DATE AND TERM OF THE PLAN

            A.    The Plan became effective when adopted by the Board in April
1995 and was approved by the Corporation's shareholders in April 1995. On August
8, 1995, the Board approved a 250,000-share increase in the number of shares
authorized for issuance over the term of the Plan. The increase was approved by
the Corporation's shareholders on November 28, 1995. On November 28, 1995, the
Board approved a further 250,000-share increase in the


                                       8.
   9
number of shares authorized for issuance over the term of the Plan. However, no
option granted in reliance upon such share increase may be exercised until the
increase is approved by the Corporation's shareholders. If such shareholder
approval is not obtained within twelve (12) months after the date of the Board's
adoption of the Plan, then all options previously granted in reliance upon such
increase shall terminate and cease to be outstanding, and no further options
shall be granted. Subject to such limitation, the Plan Administrator may grant
options under the Plan at any time after the effective date of the Plan and
before the date fixed herein for termination of the Plan.

            B.    The Plan shall terminate upon the earliest of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for issuance
under the Plan shall have been issued or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. Upon such Plan
termination, all options and unvested stock issuances outstanding under the Plan
shall continue to have full force and effect in accordance with the provisions
of the documents evidencing such options or issuances.

      IV.   AMENDMENT OF THE PLAN

            A.    The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall, without the consent of the Optionees, adversely
affect their rights and obligations under their outstanding options. In
addition, the Board shall not, without the approval of the Corporation's
shareholders, (i) increase the maximum number of shares issuable under the Plan,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) materially modify the eligibility
requirements for Plan participation or (iii) materially increase the benefits
accruing to Plan participants.

            B.    Options may be granted under the Plan to purchase shares of
Common Stock in excess of the number of shares then available for issuance under
the Plan, provided any such options actually granted may not be exercised until
there is obtained shareholder approval of an amendment sufficiently increasing
the number of shares of Common Stock available for issuance under the Plan. If
such shareholder approval is not obtained within twelve (12) months after the
date the excess grants are first made, then any options granted on the basis of
such excess shares shall terminate and cease to be outstanding.

      V.    USE OF PROCEEDS

            Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.


                                       9.
   10
      VI.   REGULATORY APPROVALS

            The implementation of the Plan, the granting of any option hereunder
and the issuance of any shares of Common Stock upon the exercise of any option
shall be subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

      VII.  NO EMPLOYMENT OR SERVICE RIGHTS

            Nothing in the Plan shall confer upon the Optionee any right to
continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or
Subsidiary employing or retaining Optionee) or of the Optionee, which rights are
hereby expressly reserved by each, to terminate the Optionee's Service at any
time for any reason, with or without cause.

      VIII. FINANCIAL REPORTS

            The Corporation shall deliver a balance sheet and an income
statement at least annually to each individual holding an outstanding option
under the Plan, unless such individual is a key Employee whose duties in
connection with the Corporation (or any Parent or Subsidiary) assure such
individual access to equivalent information.


                                      10.

      per share of Common Stock on the date in question on the Stock Exchange
      determined by the Plan Administrator to be the primary market for the
      Common Stock, as such price is officially quoted in the composite tape of
      transactions on such exchange. If there is no closing selling price for
      the Common Stock on the date in question, then the Fair Market Value shall
      be the closing selling price on the last preceding date for which such
      quotation exists.
