                         1998 NON-EMPLOYEE DIRECTORS
                              STOCK OPTION PLAN



ARTICLE 1.  PURPOSE

         The purpose of this 1998 Non-Employee Directors Stock Option Plan is to
promote the interests of ATG Inc., its subsidiaries and shareholders, by having
non-employee directors of the Company acquire a proprietary interest in the
Company. Such investments should increase the personal interest and the special
effort of such persons in providing for the continued success and progress of
the business of the Company and should enhance the Company's efforts to attract
and retain competent non-employee directors.

ARTICLE 2.  DEFINITIONS AND CONSTRUCTION

         1 Definitions. As used in the Plan, terms defined parenthetically
immediately after their use or otherwise herein shall have the respective
meanings provided by such definitions, and the terms set forth below shall have
the following meanings (in either case, such terms shall apply equally to both
the singular and plural forms of the terms defined):

           (a) "Board" shall mean the Board of Directors of the Company.

           (b) "Cause" shall mean, unless otherwise defined in an Option
Agreement, a felony conviction of a Non-Employee Director or the failure of a
Non-Employee Director to contest prosecution for a felony, or a Non-Employee
Director's willful misconduct, gross negligence or dishonesty or the
Non-Employee Director's breach of his or her fiduciary duty to the Company or
its shareholders, any of which is determined by the Board to be directly and
materially harmful to the business or reputation of the Company or its
Subsidiaries.

           (c) "Change in Control" shall mean any of the following
events:

                (1)     An acquisition (other than directly from the Company)
of any voting securities of the Company ("Voting Securities") by any Person
immediately after which such Person has Beneficial Ownership (within the meaning
of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of the combined
voting power of the Company's then outstanding Voting Securities; provided,
however, that in 

                                       1
<PAGE>
 
determining whether a Change in Control has occurred, Voting Securities which
are acquired in a Non-Control Acquisition (as hereinafter defined) shall not
constitute an acquisition which would cause a Change in Control. A Non-Control
Acquisition shall mean an acquisition by (i) the Company or any Subsidiary,
(ii) an employee benefit plan (or a trust forming a part thereof) maintained
by the Company or any Subsidiary or (iii) any Person in connection with a Non-
Control Transaction (as hereinafter defined);

                (2)     The individuals who, as of the Effective Date, are
members of the Board ("Incumbent Board") cease for any reason to constitute at
least a majority of the Board; provided, however, that if the election, or
nomination for election by the Company's shareholders, of any new director was
approved by a vote of at least a majority of the Incumbent Board, such new
director shall, for purposes of the Plan, be considered as a member of the
Incumbent Board; provided, further, however, that no individual shall be
considered a member of the Incumbent Board if such individual initially assumed
office as a result of either an actual or threatened election contest (as
described in Rule 14a-11 promulgated under the Exchange Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person other
than the Board ("Proxy Contest") including by reason of any agreement intended
to avoid or settle any such election contest or Proxy Contest; or

                (3)     Approval by shareholders of the Company of:

                        (A)      A merger, consolidation or reorganization
involving the Company, unless such is a Non-Control Transaction. For purposes of
the Plan, the term "Non-Control Transaction" shall mean a merger, consolidation
or reorganization of the Company in which:

                                  (i)  the shareholders of the Company
immediately before such merger, consolidation or reorganization, own, directly
or indirectly immediately following such merger, consolidation or
reorganization, at least a majority of the combined voting power of the
outstanding voting securities of the corporation resulting from such merger,
consolidation or reorganization ("Surviving Corporation") in substantially the
same respective proportions as their ownership of the Voting Securities
immediately before such merger, consolidation or reorganization;

                                  (ii) The individuals who were members of the
Board immediately prior to the execution of the agreement providing for such
merger, consolidation or reorganization constitute at least a majority of the
members of the board of directors of the Surviving Corporation; and

                                       2
<PAGE>
 
                                  (iii) no Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan (or any trust forming a
part thereof) maintained by the Company, the Surviving Corporation or any
Subsidiary of the Company, or any Person who, immediately prior to such merger,
consolidation or reorganization had Beneficial Ownership (within the meaning of
Rule 13d-3 promulgated under the Exchange Act) of 20% or more of the then
outstanding Voting Securities) has Beneficial Ownership of 20% or more of the
combined voting power of the Surviving Corporation's then outstanding voting
securities;

                         (B)      A complete liquidation or dissolution of the
Company; or

                         (C) An agreement for the sale or other disposition of
all or substantially all of the assets of the Company to any Person (other
than a transfer to a Subsidiary).

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur
solely because any Person ("Subject Person") acquired Beneficial Ownership of
more than the permitted amount of the outstanding Voting Securities as a result
of the acquisition of Voting Securities by the Company which, by reducing the
number of Voting Securities outstanding, increases the proportional number of
shares Beneficially Owned by the Subject Person; provided, however, that if a
Change in Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Company, and after such
share acquisition by the Company the Subject Person becomes the Beneficial Owner
of any additional Voting Securities which increases the percentage of the then
outstanding Voting Securities Beneficially Owned by the Subject Person, then a
Change in Control shall be deemed to occur.

                  (d) "Code" shall mean the Internal Revenue Code of 1986, as
amended from time to time, and any successor thereto.

                  (e) "Company" shall mean ATG Inc., a California corporation.

                  (f) "Disability" shall mean the total disability as determined
by the Board in accordance with standards and procedures similar to those under
the Company's long-term disability plan, or, if none, a physical or mental
infirmity which the Board determines impairs the participant's ability to
perform substantially his or her duties as a Non-Employee Director for a period
of 180 consecutive days.

                  (g) "Exchange Act" shall mean the Securities Exchange Act of
1934, as amended from time to time.

                  (h) "Fair Market Value" of the Shares shall mean as of any
applicable date, the closing sale price of the Shares on the Nasdaq National
Market or any national or regional stock exchange on which the Shares are
traded, or if no such reported sale of the Shares shall have occurred on such
date, on the next preceding date on which there was such a reported sale. If
there shall be any material alteration in the present system of reporting sale
prices of the Shares, or if the Shares shall no longer be included in the Nasdaq
National Market or listed on a national or regional stock exchange, the Fair
Market Value of the Shares as of a particular date shall be determined by such
method as shall be determined by the Board.

                  (i) "Initial Grant Date" shall mean the date the Registration
Statement with respect to the Company's initial public offering of Shares
becomes effective.

                  (j) "Non-Employee Director" shall mean a member of the Board

who has the right to exercise the Option upon the death of the Optionee.

                  (o) "Person" shall have the meaning ascribed to such term in
Section 3(a)(9) of the Exchange Act and as used in Sections 13(d) and 14(d)
thereof, including a "group"' as defined in Section 13(d).

                  (p) "Plan" shall mean this 1998 Non-Employee Directors Stock

         3 Severability. In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included, to the maximum extent
permitted by applicable law.

ARTICLE 3.  GRANTING OF OPTIONS

         1 Non-Employee Directors Grants. Each Non-Employee Director shall
automatically be granted an Option to purchase 20,000 Shares upon the later of
(a) the initial date of his or her election to the Board or (b) the Initial
Grant Date, provided that the number of Shares available for grant under the
Plan is sufficient to permit such automatic grant.

         2 Proportionate Reduction. If as of any date on which there is to be a
grant of Options hereunder there is an insufficient number of Shares available
pursuant to Article 4 to make all of the grants then to be made, each
Non-Employee Director then entitled to be granted an Option shall receive an
Option to purchase a proportionately lesser number of Shares.

ARTICLE 4.  SHARES SUBJECT TO THE PLAN

         The stock subject to options granted under the Plan shall be the
Shares. Subject to the adjustments provided for in Article 7, the aggregate
number of Shares to be delivered upon exercise of all Options granted under the

only to Non-Employee Directors.

         2        Non-Transferability of Options. No Option shall be
transferable by the Optionee otherwise than by bequest or the laws of descent
and distribution, and each Option shall be exercisable during the Optionee's
lifetime only by the Optionee; provided, however, that the Optionee may
transfer the Options to the Optionee's spouse, lineal descendants, trusts for
their benefit or a charitable remainder trust of which the Optionee or such
family members referred to above are beneficiaries.

         3        Termination of Option.

                  (a) If the Optionee ceases to be a director of the Company for
any reason other than death, Disability or removal for Cause, the Option shall
terminate three months after the Optionee ceases to be a director of the Company
(unless the Optionee dies during such period), or on the Option's expiration
date, if earlier, and shall be exercisable during such period after the Optionee
ceases to be a director of the Company only with respect to the number of Shares
which the Optionee was entitled to purchase on the day preceding the day on
which the Optionee ceased to be a director.

                  (b) If the Optionee ceases to be a director of the Company
because of removal for Cause, the Option shall terminate on the date of the
Optionee's removal.

the Option shall terminate upon the earlier to occur of (A) 12 months after the
date of the Optionee's death or Disability; or (B) the Option's expiration date
(as provided in Section 5.6). The Option shall be exercisable during such period
after the Optionee's death or Disability with respect to the number of Shares as
to which the Option shall have been exercisable on the date preceding the
Optionee's death or Disability, as the case may be.

         7 Exercisability. The time at which the Option becomes exercisable.
The Option shall be exercisable as follows:

additional 25% of the Shares subject to the Option.

                  (d) Beginning on the day following the third anniversary of
the date the Option is granted, the Option may be exercised with respect to all
of the Shares subject to the Option.

Notwithstanding the provisions of this Section 5.7, upon a Change in Control the
Optionee shall have the right to exercise the Option in full as to all Shares
subject to the Option.

         8 Exercise and Payment of Option Price. Options shall be exercised by
delivery to the Company of a written notice of exercise, setting forth the
number of Shares with respect to which the Option is to be exercised and

in cash at the time of exercise, except that in lieu of all or part of the cash,
the Optionee may tender to the Company Shares owned by the Optionee having a
Fair Market Value equal to the Option price, less any cash paid. The Fair Market
Value of such tendered Shares shall be determined as of the close of the
business day immediately preceding the day on which the Option is exercised;
except that in the case of any Plan participant subject to Section 16(b) of the
Exchange Act such cashless exercise of his or her Option may not occur within
six months of the date of grant of such Option, to the extent such exercise
during such six-month period would not be exempted from Section 16(b) of the
Exchange Act by virtue of Rule 16b-3 promulgated thereunder.

ARTICLE 6.  ADMINISTRATION

         1 The Administrator. The Plan is designed to operate automatically and
not require any significant administration. To the extent administration is
required, the Plan shall be administered by the Board. The Board shall meet at
such times and places as it determines and may meet through telephone conference
call. A majority of its members shall constitute a quorum, and the decision of
the majority of those present at any meeting at which a quorum is present shall
constitute the decision of the Board. Any decision reduced to writing and signed
by a majority of the members of the Board shall be fully effective as if it had
been made by a majority at a meeting duly held. All decisions, determinations
and selections made by the Board pursuant to the provisions of the Plan shall be
final. To the extent required by law and Rule 16b-3 promulgated under the
Exchange Act, the Board may delegate its authority hereunder.

         2 Section 16 Compliance. It is the intention of the Company that the
Plan and the administration of the Plan comply in all respects with Section
16(b) of the Exchange Act and the rules and regulations promulgated thereunder.
If any Plan provision, or any aspect of the administration of the Plan, is found
not to be in compliance with Section 16(b) of the Exchange Act, the provision or
administration shall be deemed null and void, and in all events the Plan shall
be construed in favor of its meeting the requirements of Rule 16b-3 promulgated
under the Exchange Act. Each Optionee shall deliver to the Corporate Secretary
of the Company an executed notice of his/her intention to sell Shares acquired
upon exercise, in whole or in part, of the Option granted hereunder. Such
notice, in which there is specified the number of shares which are to be sold
and the date such shares were acquired, shall be provided at least one full
business day in advance of the proposed date of sale.

ARTICLE 7.  ADJUSTMENTS UPON CHANGE IN CAPITALIZATION

         Notwithstanding the limitations set forth in Article 4, in the event of
a merger, consolidation, reorganization, recapitalization, reclassification,
split-up, spin-off, stock dividend, stock split, reverse stock split, property
dividend, share repurchase, share combination, share exchange or other
fundamental change in the corporate structure of the Company affecting the
Shares, the Board shall make an appropriate and equitable adjustment in the
maximum number of Shares available under the Plan and in the number, kind and
Option Price of Shares subject to Options granted under the Plan to prevent
dilution or enlargement of the rights of Non-Employee Directors under the Plan
and outstanding Options.

conditions for exemption from Section 16(b) of the Exchange Act or the
requirements of any regional or national securities exchange or over-the-counter
national market system on which the Shares are then listed, included or reported
or a regulatory body having jurisdiction with respect thereto, without the
approval of the shareholders of the Company, no discontinuation, amendment,
modification or termination may:

                  (a) materially increase the benefits accruing to Non-Employee
Directors under the Plan;

                  (b) materially increase the total number of Shares which may
be issued under the Plan, except as provided in Article 7; or

                  (c) materially modify the eligibility requirements to receive
an Option under the Plan.

         3 No Effect on Outstanding Options. Any Option which is outstanding
under the Plan at the time of its amendment or termination shall remain in
effect in accordance with its terms and conditions and those of the Plan as in
effect when the Option was granted.

ARTICLE 9.  MERGER, CONSOLIDATION, ETC.

         1 Conversion on Certain Mergers and Other Transactions. In the event
that the Company merges or consolidates with another corporation, or all or
substantially all of the Company's capital stock or assets are acquired by
another corporation, and the surviving or acquiring corporation issues shares of
its stock to the Company's shareholders in connection with the merger,
consolidation or acquisition, the surviving or acquiring corporation shall adopt
the Plan and upon the exercise of an Option, the Optionee shall, at no
additional cost (other the Option Price), be entitled to receive, in lieu of the
number of Shares with respect to which such Option is then exercisable, the
number and class of stock or other securities to which the Optionee would have
been entitled pursuant to the terms of the merger, consolidation or acquisition
if immediately prior thereto the Optionee had been the holder of record of a
number of Shares equal to the number of Shares as to which the Option shall then
be exercisable.

                                       9

         2 No Conversion on Mergers and Other Transactions. In the event that
the Company merges or consolidates with another corporation, or all or
substantially all of the Company's capital stock or assets are acquired by
another corporation, and the surviving or acquiring corporation does not issue
shares of its stock to the Company's stockholders in connection with the merger,
consolidation or acquisition, then, notwithstanding any other provision of the
Plan to the contrary, no Option may be exercised after the effective date of the
merger, consolidation or acquisition.

ARTICLE 10.  EFFECTIVENESS AND TERMINATION OF THE PLAN

         1 Effective Date. The Plan shall become effective only upon its
adoption by the Board, or the date the initial public offering of the Company's
Common Stock is consummated, whichever comes later (the "Effective Date"). The

unless within 12 months from the Effective Date it shall have been approved by
the holders of a majority of the outstanding Shares.

of (1) the date when all of the Shares available under the Plan shall have been

after the Effective Date; or (iii) such other date as the Board may determine.

ARTICLE 11.  NO RIGHT OF REELECTION

         Neither the Plan, nor my action taken under the Plan, shall be

director of the Company, to be renominated by the Board or reelected by the
shareholders of the Company.
