         NOW, THEREFORE, in consideration of the Investors' agreement to
purchase Series B Preferred Stock pursuant to the Purchase Agreement, the

the Advanced Research Projects Agency ("ARPA") which grants will be designated
for the research, development and engineering of Equipment by SVGL. In the event
the Company is successful in obtaining such grants the Company will use and
cause SVGL to use the first $25,000,000 of the proceeds of any grants or funds

designated for photolithography purposes for development and design of
Equipment.

                 (c) The Company agrees to use and cause SVGL to use
commercially reasonable efforts to continue the development of Equipment and to
timely reach the milestones set forth in its development agreements dated as of

grants from Sematech designated for photolithography purposes contemplated by
such agreements.

                 (d) In addition to the obligations set forth under Sections
1.1(a), (b) and (c) above, the Company agrees to invest in SVGL funds reasonably

expand its manufacturing capacity to meet orders for Equipment from customers
and to expand its research and development capacity, (ii) to enable SVGL to meet
its commitments to customers to produce and deliver Equipment, [*] (iv) to
provide sufficient working capital.

         1.2     Covenants Regarding Development of the Equipment.

jointly develop one or more future generations of the Equipment. Any such third
party is referred to herein as a "Future Licensee". The Company and SVGL agree
to use commercially reasonable efforts to cause any agreement under which the
Company and/or SVGL licenses its Micrascan technology to a Future Licensee to
include a provision under which such Future Licensee will agree that if it has

Equipment and any future generation of Equipment, to achieve the goals set forth

                         (ii)   [*] Every 90 days, the Company or SVGL and such
Investor will evaluate whether the Contingency still exists. [*] The Company and

         1.5     Statement of Applications of Funds;  Audit.

                 (a)     At least one time every six months until the proceeds 
of the sale of Series B Preferred Stock have been exhausted, the Company shall
cause SVGL to provide each Investor a Statement of Applications of Funds
("Statement"). Such Statement shall set forth the use of proceeds from the sale
of Series B Preferred Stock to the Investors.

                 (b)     Each Investor shall have the right to verify that any 
such Statement accurately describes SVGL's and the Company's use of such 
proceeds by having an audit conducted, during normal business hours, of the 
books and records of the Company and SVGL.

         Such audit shall be performed by a nationally recognized independent
accounting firm mutually acceptable to the Company or SVGL and all participating
Investors, which consent shall not be unreasonably withheld. Any Investor may
exercise the audit right set forth herein by sending written notice to the

borne by the participating Investors pro rata according to their relative
holdings of Series B Preferred Stock. Each participating Investor shall receive
one copy of the audit report generated by the audit firm. Only one audit may be

         1.6     No Sale, Merger, Consolidation, etc. of the Company. Until the
third anniversary of the Closing Date, the Company shall not, without the prior
consent of two of the Investors, enter into a Transaction; provided, that if the
surviving entity of a Transaction assumes all of SVG or SVGL's, as the case may
be, obligations under this Agreement and such surviving entity is, in the good
faith reasonable judgment of the Investors, as capable of meeting such
obligations after the Transaction as the Company or SVGL was before the
Transaction, a Transaction will not require the prior consent of the Investors.
For the purposes of this Section 1.6, a Transaction shall mean:

                 (a) The sale by the Company or SVGL of all or substantially all
of its assets to an entity (other than the Company) as to which neither the
Company, nor the stockholders of the Company immediately prior to the
consummation of such sale, nor the Company and such stockholders together, hold
voting securities representing 50% or more of the voting power of such entity
immediately following the consummation of such sale;

                 (b) The consummation by SVGL of a merger, consolidation or
other transaction or series of transactions pursuant to which neither the
Company nor the stockholders of the Company immediately prior to such
consummation, nor the Company and such stockholders together, hold voting
securities representing a majority of the voting power of the surviving entity
immediately following such consummation;

                 (c) A sale by the Company or SVGL of all or substantially all
of their assets to any entity as to which neither the Company, nor the
stockholders of the Company immediately prior to such sale, nor the Company and
such stockholders together, hold voting securities representing a majority of
the voting power of the surviving entity immediately following such sale; or

                 (d) The consummation by the Company or SVGL of a merger,
consolidation or other transaction or series of transactions pursuant to which
the stockholders of the Company immediately prior to such consummation fail to
hold voting securities representing a majority of the voting power of the
surviving entity immediately following such consummation.

                 (e) Until such time as the Stockholders Agreement by and among
IBM, SVGL, The Perkin-Elmer Corporation and the Company dated May 15, 1990 (the
"IBM Agreement") shall have terminated, any event or transaction that would
trigger IBM's right to purchase SVGL pursuant to Section 8.1 of the IBM
Agreement and any event or transaction that would trigger IBM's right of first
refusal pursuant to Section 9.2 of the IBM Agreement; provided, that if IBM
agrees in writing not to exercise its rights under the IBM Agreement, no
Transaction shall be deemed to have occurred for purposes of this Section
1.6(e).

         1.7     Board Visitation Rights.

                 (a) For so long as an Investor holds 100% of the shares of
Series B Preferred Stock purchased pursuant to the Purchase Agreement (or such
number of shares of common stock of the Company ("Common Stock") into which the
Series B Preferred Stock is convertible) such Investor shall have the right to
receive notice of all meetings of the Company's Board of Directors and a copy of
all materials sent to each director in connection with meetings of the Board of
Directors and to send one (1) representative to attend all meetings of the
Company's Board of Directors as an observer, upon the terms and subject to the
conditions hereof. Such representative shall not participate in the
deliberations of the Board of Directors and shall have no power to vote on
matters considered by the Board.

                 (b) Each Investor acknowledges that the Company's Board of
Directors may from time to time discuss matters involving a conflict of interest
on the part of such Investor such as discussions concerning competitors of the
Investor or relations between the Company and the Investor or may from time to
time discuss personnel matters. Accordingly, the Company shall have the right
(upon exercise of the good faith judgment of the Company's Board of Directors)
to cause the representative of such Investor to excuse himself or herself from
such discussions. In the event the Company shall cause the representative to be
so excused, the Company shall refrain from sending or providing to such
representative any information otherwise disseminated to the directors of the
Company concerning the matter from which the representative has been excused.

                 (c) Each Investor acknowledges that by receipt of the materials
and by participation in the meetings described above, such Investor may learn
material, nonpublic information about the Company and that, as a result, such
Investor may be precluded from selling any securities of the Company until such
information has been publicly disclosed. Each Investor agrees that, for so long
as it is receiving such material or such Investor's representative is attending
such meetings, such Investor will abide by the trading window and other
restrictions of the Company's insider trading policies as they apply, from time
to time, to directors of the Company.

                 (d) The right set forth in this Section 1.7 shall be personal 
to each Investor and shall not be transferable or assignable.

efforts to cause all employees of SVGL to sign SVGL's standard proprietary
invention and confidential information agreement.

         1.9     IBM Ownership of SVGL. The Company and SVGL agree to use best
efforts to cause IBM to exchange its shares of capital stock of SVGL for shares
of Common Stock under commercially reasonable financial terms and to amend, to
the mutual satisfaction of the Company and the Investors, the terms of the Asset
Purchase Agreement dated as of May 15,

1990, among the Company, SVGL, IBM and the Perkin-Elmer Corporation and the
terms of the IBM Agreement within nine months of the Closing Date.

         1.10 Redemption Upon Breach of Covenant. In the event that the Company
or SVGL breaches any covenant contained in this Agreement or the Purchase
Agreement, and such breach is not cured within 30 days following receipt of
written notice of such breach, and as long as an Investor owns 100% of the
Series B Preferred (or the Common Stock into which it is convertible) purchased
pursuant to the Purchase Agreement (the "Original Purchase"), holders of
two-thirds of the Series B Preferred (or Common Stock in to which it is
convertible) constituting their Original Purchase shall have the right to
require the Company to immediately redeem all such Original Purchase shares. The
redemption price per share of Series B Preferred shall be the greater of (i)
$2,208.80 (as adjusted for stock splits, combinations, etc.) plus all dividends
(whether or not earned or declared) accrued and unpaid to the date of the breach
of the covenant set forth in the written notice, and (ii) 100 times the average
of the closing sale prices of the Common Stock for the 10 trading days preceding
the date of the breach set forth in the written notice to the Company. The
redemption price per share of Common Stock shall be the greater of $22.08 (as
adjusted for stock splits, combinations, etc.) plus all dividends (whether or
not earned or declared) accrued and unpaid to the date of the breach of the
Covenant set forth in the written notice, and (ii) the average of the closing
sale price of the Common Stock for the 10 trading days preceding the date of the
breach set forth in the written notice to the Company. The closing of the
redemption of the Series B Preferred (or the Common Stock into which it has been
converted) shall occur no later than 30 days after delivery of written notice of
the Purchasers' election to require the Company to redeem the outstanding shares
of Series B Preferred (or the Common Stock into which it has been converted).
Notwithstanding the foregoing, if such redemption is prohibited by law, the
Company shall not be required to effect such redemption until such time as such
redemption is no longer prohibited by law.

                                    SECTION 2

                                  Miscellaneous

         2.1  Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to the Company or the Investors, upon any breach or
default under this Agreement, shall impair any such right, power or remedy, nor
shall it be construed to be a waiver of any such breach or default, or any
acquiescence therein, or of any similar breach or default thereafter occurring;

other breach or default theretofore or thereafter occurring. Any waiver, permit,
