                  STOCK OPTION AGREEMENT, dated as of ______________ (the "GRANT
DATE"), between TTM Technologies, Inc., a Washington corporation (the
"COMPANY"), __________ (the "PARTICIPANT").

                  1. DEFINITIONS; INCORPORATION OF PLAN TERMS. Capitalized terms
used herein without definition shall have the meanings assigned to them in the
TTM Technologies, Inc. Amended and Restated Management Stock Option Plan (the
"PLAN"), a copy of which is attached hereto. This Agreement, the option granted
hereunder (the "OPTION") and the Option Shares issued pursuant to the exercise
of Options shall be subject to the Plan, the terms of which are hereby
incorporated herein by reference, and in the event of any conflict or
inconsistency between the Plan and this Agreement, the Plan shall govern.

                  2.  SHAREHOLDERS AGREEMENT; RESTRICTIONS ON TRANSFER.

                  (a) By executing this Option Agreement, the Participant shall
become a party to the Shareholders Agreement, and this Option and all Option
Shares issued hereunder shall be subject to the Shareholders Agreement. The
Participant shall not have any rights as a shareholder with respect to any
shares of Common Stock issuable upon exercise of an Option until the Option
Price has been paid in full and all other conditions to the exercise of the
Option set forth in the Plan and this Agreement have been satisfied.

                  (b) This Option may not be sold, offered, disposed of,
pledged, hypothecated, encumbered or otherwise transferred by the Participant
except, in the event of the Participant's death, to the Participant's executors,
administrators and testamentary trustees or as provided in the Shareholders
Agreement. During the lifetime of the Participant, the Option may be exercised
only by, or on behalf of, the Participant.

                  3. GRANT OF OPTIONS. Subject to the terms and conditions
contained herein and in the Plan, the Company hereby grants to the Participant,
effective as of the Grant Date, the number of A Options and B Options set forth
on the signature page hereto. Each such Option shall entitle the Participant to
purchase, upon payment of the Option Price specified at the foot of the
signature page hereof, one share of Common Stock; PROVIDED, HOWEVER, that such
Options may also be exercisable for fractional shares of Common Stock. The
Options shall be exercisable as hereinafter provided.

                  4. TERMS AND CONDITIONS OF OPTIONS. Except as otherwise
provided in the Plan, the Options granted hereunder shall vest and become
exercisable as follows:

<PAGE>

                  (a) A OPTIONS. Subject to the Participant's continued
employment or service with the Company and its Subsidiaries, the following
vesting rules shall apply to all A Options:

                  (i) All A Options shall vest on the eighth anniversary of the
Grant Date.

                  (ii) Upon the occurrence of a Liquidity Event, the Applicable
         Portion of the A Options shall vest on an accelerated basis. For
         example, if upon a 50% Liquidity Event (e.g., a sale by Thayer and
         Brockway Moran of 50% of their respective interests) the Annualized
         Rate of Return (i.e., the compounded annual rate of return on the stock
         of the Company between the Commencement Date and date of the Liquidity
         Event) equals 35%, then 50% of the A Options will become vested on an
         accelerated basis. Schedule A sets forth the factors used in
         determining A Option vesting and illustrates various vesting scenarios.

                  (iii) Upon the occurrence of a Liquidity Event, (A) the excess
         of the Eligible Portion of the A Options over the Applicable Portion of
         the A Options shall no longer be eligible for accelerated vesting under
         Section 4(a)(ii) and shall vest in accordance with Section 4(a)(i) and
         (B) the excess of the aggregate number of A Options over the Eligible
         Portion of the A Options will continue to be eligible for accelerated
         vesting under Section 4(a)(ii).

                  For purposes of this Section 4, the following terms shall have
the meanings set forth below:

                  "ANNUALIZED RATE OF RETURN" means, with respect to the Common
         Stock as of any Liquidation Event, the compounded annual rate of return

                  X        =        Aggregate Return ^[(365)Y] - 1; and

                  "BASE AMOUNT" means the number of shares of Common Stock held

<PAGE>

                  B        =        a fraction, the numerator of which is the
                                    aggregate number of shares of Common Stock
                                    disposed by the Principal Stockholders

                  (b) B OPTIONS. Subject to the Participant's continued
employment or service with the Company or its Subsidiaries, 20% of the B Options

         and Unvested) shall immediately expire.

                  (ii) RESIGNATION. In the event of the Participant's
         resignation for any reason, then all of such Participant's Unvested
         Options shall immediately expire and the Participant's Vested Options
         shall remain exercisable for a period of 30 days following such
         resignation.

                  (iii) TERMINATION OTHER THAN FOR CAUSE. In the event of the
         termination of the Participant's employment or service relationship the
         Company or any of its Subsidiaries other than for Cause, then the
         Participant's Unvested Options shall be treated as follows:

                           (A) A pro rata portion of the Participant's Unvested
                  B Options which were scheduled to vest during the 12-month
                  period commencing on the Grant Date or any anniversary of the
                  Grant Date in which such termination occurs (based on the
                  number of days elapsed in such 12-month period prior to such


                                       5
<PAGE>

                  termination) shall become vested and shall remain exercisable
                  for a period of 90 days after such termination.

                           (B) If such termination occurs before the date which
                  is 18 months before the eighth anniversary of the Grant Date,
                  the Participant's Unvested A Options shall remain outstanding
                  for nine months after such termination of employment or
                  service and shall be eligible for accelerated vesting in the
                  manner set forth in Section 4(a) upon the occurrence of a
                  Liquidity Event as if the Participant's employment or service
                  had not terminated, and, to the extent any such accelerated
                  vesting occurs, shall remain exercisable for a period of 90
                  days following such accelerated vesting. Any such Unvested A
                  Options that do not vest on an accelerated basis during the
                  nine-month period following such termination shall expire at
                  the end of such period.

                           (C) If such termination occurs on or after the date
                  which is 18 months before the eighth anniversary of the Grant
                  Date but before the date which is six months before the eighth
                  anniversary of the Grant Date, then 50% of the Participant's
                  Unvested A Options shall become Vested on an accelerated basis
                  at such time and shall remain exercisable for a period of 90
                  days following such accelerated vesting.

                           (D) If such termination occurs on or after the date
                  which is six months before the eighth anniversary of the Grant
                  Date, then 100% of the Participant's Unvested A Options shall
                  become Vested on an accelerated basis at such time and shall
                  remain exercisable for a period of 90 days following such
                  accelerated vesting.

                  (iv) DEATH OR DISABILITY. If the Participant's employment or
         service with the Company or any of its Subsidiaries terminates due to
         the Participant's death or Disability, then the Participant's Unvested
         Options shall be treated as follows:

                           (A) A pro rata portion of the Participant's Unvested
                  B Options which were scheduled to vest during the 12-month
                  period commencing on the Grant Date or any anniversary of the
                  Grant Date in which the Participant's death or Disability
                  occurs (based on the number of days elapsed in such 12-month
                  period prior to such termination) shall become vested and
                  shall remain exercisable for a period of one year after such
                  termination.

                           (B) The Participant's Unvested A Options shall remain
                  outstanding for 18 months after the Participant's death or
                  Disability and shall be eligible for


                                       6
<PAGE>

                  accelerated vesting in the manner set forth in Section 4(a)
                  upon the occurrence of a Liquidity Event as if the
                  Participant's employment or service had not terminated, and,
                  to the extent any such accelerated vesting occurs, shall
                  remain exercisable for a period of one year following such
                  accelerated vesting. Any such Unvested A Options that do not
                  vest on an accelerated basis during the 18-month period
                  following such termination shall expire at the end of such
                  period; PROVIDED, HOWEVER, that if the eighth anniversary of
                  the Grant Date occurs during such 18-month period, all of the
                  Participant's Unvested A Options shall vest at such time and
                  shall remain exercisable for a period of one year.

                  (v) CHANGE IN CONTROL. If the Participant's employment or
         service with the Company or any of its Subsidiaries is terminated
         without Cause within one-year following a Change in Control, then the
         Participant's Unvested Options shall be treated as follows:

                           (A) All of the Participant's Unvested B Options shall
                  vest and shall remain exercisable for a period of 90 days
                  after such termination.

                            (B) The Applicable Excess Portion of the A Options
                  shall vest on an accelerated basis and shall remain
                  exercisable for a period of 90 days after such termination.
                  For example, if the Participant's employment or service with
                  the Company or any of its Subsidiaries is terminated without
                  Cause within one year following a 50% Liquidity Event (e.g., a
                  sale by the Principal Stockholder of 50% of their respective
                  interests) and the Annualized Rate of Return at the time of
                  the Liquidity Event equaled 35%, then the remaining 50% of the
                  A Options that did not vest upon the Liquidity Event will
                  become vested on an accelerated basis. Schedule A sets forth
                  the factors used in determining A Option vesting and
                  illustrates various vesting scenarios.

                  5. REPRESENTATIONS AND WARRANTIES. (a) The Participant hereby
represents that the Participant is aware of and familiar with the restrictions
imposed on the transfer of any share of Common Stock and Options, including,
without limitation, the restrictions contained in this Agreement and the Plan.

                  (b) In the event the Option Shares have not been registered
under the Securities Act at the time the Participant's Options are exercised in
whole or in part, the Participant shall represent to the Company the following:

                  (i) The Participant is aware of the Company's business affairs
         and financial condition and has acquired sufficient information about
         the Company to reach an


                                       7
<PAGE>

         informed and knowledgeable decision to acquire the securities. The
         Participant is purchasing these securities for investment for the
         Participant's own account only and not with a view to, or for resale
         in connection with, any "distribution" thereof within the meaning of
         the Securities Act of 1933, as amended (the "SECURITIES Act").

                  (ii) The Participant understands that the securities have not
         been registered under the Securities Act by reason of a specific
         exemption therefrom, which exemption depends upon, among other things,
         the bona fide nature of the Participant's investment intent as
         expressed herein. In this connection, the Participant understands that,
         in the view of the Securities Exchange Commission, the statutory basis
         for such exemption may not be present if the Participant's
         representations meant that the Participant's present intention was to
         hold these securities for a minimum capital gains period under the tax
         statutes, for a deferred sale, for a market rise, for a sale if the
         market does not rise, or for a year or any other fixed period in the
         future.

                  (iii) The Participant further acknowledges and understands
         that the securities must be held indefinitely unless they are
         subsequently registered under the Securities Act or an exemption from
         such registration is available. The Participant further acknowledges
         and understands that the Company is under no obligation to register the
         securities. The Participant understands that the certificate evidencing
         the securities will be imprinted with a legend which prohibits the

                                   SCHEDULE A

                           A OPTION VESTING SCENARIOS


                  The A Options granted under the Plan are "performance-vesting"
options. This means that certain performance criteria must be satisfied in order
for them to vest on an accelerated basis. If the performance criteria are never
met, the A Options will not vest until the eighth anniversary of the Grant Date.
Unlike the A Options, the B Options vest over time (20% per year for five years,
commencing on the first anniversary of the Grant Date). The illustrations below
apply only to the A Options.

                  The following examples are intended to illustrate the
mechanics of the vesting of A options under the Plan. They are intended as
illustrations only and are not an indication of the actual performance of the
Common Stock or the future value of the A Options that have been granted under
the Plan.

                  The vesting of Options is dependent on the following factors:

                  OCCURRENCE OF A LIQUIDITY EVENT.

                  X        All Unvested A Options will vest on the eighth
                           anniversary of grant. However, A Options may vest
                           earlier upon the occurrence of a Liquidity Event
                           under certain circumstances.

                  X       "LIQUIDITY EVENT" is defined in the Plan as a sale or
                           other disposition of the Common Stock by entities
                           holding Common Stock which are controlled by Thayer
                           Capital Partners and Brockway Moran & Partners
                           (defined in the Plan as the "PRINCIPAL
                           STOCKHOLDERS").

                  AMOUNT OF COMMON STOCK DISPOSED BY PRINCIPAL STOCKHOLDERS IN
                  LIQUIDITY EVENT

                  X        The amount of A Options that will be eligible to vest
                           on any Liquidity Event depends on the amount of
                           Common Stock sold or disposed by the Principal
                           Stockholders.

                  VALUE OF COMMON STOCK AT LIQUIDITY EVENT

                  X        The amount of A Options that will vest on a Liquidity
                           Event is determined by the Annualized Rate of Return
                           on the Common Stock (the compounded


<PAGE>

                           annual rate of return on the Common Stock between
                           July 14, 1999 and the Liquidity Event).

                  X        If the Annualized Rate of Return on the Common Stock
                           is 35% or greater, all of the A Options eligible for
                           accelerated vesting on the Liquidity Event will vest.

                  X        If the Annualized Rate of Return is 25% or lower, no
                           A Options will vest on the Liquidity Event.

                  X        A proportionate amount of A Options will vest if the
                           Annualized Rate of Return is between 25% and 35%.

                  TERMINATION OF EMPLOYMENT WITHOUT CAUSE WITHIN ONE YEAR
                  FOLLOWING A LIQUIDITY EVENT

                  X        If a Participant's employment is terminated within
                           one year following a Liquidity Event then the excess
                           A Options held by the Participant that were not
                           ELIGIBLE for acceleration in connection with the
                           Liquidity Event (E.G., the Liquidity Event was for
                           less than 100% of the Principal Stockholders' Common
                           Stock holdings) will be eligible for accelerated
                           vesting in the same proportion as A Options vested at
                           the time of the Liquidity Event.
