Item 2. Acquisition or Disposition of Assets.

       On July 6, 1999, Silicon Valley Group, Inc., a Delaware corporation (the
"Registrant"), acquired the business of the Semiconductor Equipment Group of
Watkins-Johnson Company, a California corporation ("Watkins-Johnson") pursuant
to the Securities Purchase Agreement dated April 30, 1999 by and between the
Registrant and Watkins-Johnson, as amended by the Amendment No. 1 to the
Securities Purchase Agreement dated July 2, 1999 by and between the Registrant
and Watkins-Johnson (as so amended, the "Purchase Agreement"). The Registrant
currently intends to consolidate the operations of the Semiconductor Equipment
Group with its Thermco Systems division.

        Under the terms of the Purchase Agreement, the Registrant acquired from
Watkins-Johnson all of its limited liability company interests in Semiconductor
Equipment Group, LLC and the outstanding capital stock of certain foreign
subsidiaries. As consideration for the acquisition, the Registrant paid
Watkins-Johnson an initial cash payment of approximately $9.0 million, and
assumed liabilities of approximately $37.0 million. The total consideration is
subject to adjustment based on a final closing balance sheet as of July 2, 1999.
In connection with this acquisition, the Registrant also entered into a third
party lease with Key Bank, National Association ("Key Bank") covering certain
real property located in Scotts Valley, California that was transferred by
Watkins-Johnson to Key Bank for approximately $14.5 million.

        This acquisition will be accounted for using the purchase method of
accounting.

        The summary of the provisions of the Purchase Agreement set forth above
is qualified in its entirety by reference to the Purchase Agreement filed
herewith as Exhibits 2.1 and 2.2.

                amended (the "Exchange Act"), if any such information is

        This SECURITIES PURCHASE AGREEMENT (the "AGREEMENT") is made and entered
into as of April 30, 1999, by and between Silicon Valley Group, Inc., a Delaware

        Except as otherwise set forth in this Agreement, capitalized terms shall
have the definitions set forth in Section 9.10.

                                    RECITALS

        A.      The Board of Directors of each of SVG and Watkins-Johnson
believe it is in the best interests of each company and their respective
stockholders that SVG, or a subsidiary or subsidiaries of SVG, acquire (the
"ACQUISITION") the Business by purchasing (i) all of the outstanding membership
interests (the "SEG LLC INTERESTS") in a limited liability company (the "SEG
LLC") wholly owned by the SEG Sub (as defined below) immediately prior to the
Closing, (ii) all of the capital stock (collectively, the "INTERNATIONAL
SUBSIDIARY CAPITAL STOCK") of the international subsidiaries of Watkins-Johnson
listed on SCHEDULE 2.1 (collectively, the "SEG INTERNATIONAL ENTITIES" and
together with WJ Semiconductor Equipment Group, Inc., a California corporation
and wholly owned subsidiary of Watkins-Johnson (the "SEG SUB"), Watkins-Johnson
International, a California corporation and wholly owned subsidiary of SEG Sub
("WATKINS-JOHNSON INTERNATIONAL"), and the SEG LLC, the "SEG ENTITIES") and
(iii) all of Watkins-Johnson's right, title and interest in and to the Scotts
Valley Property.

        B.      A portion of the cash otherwise payable to Watkins-Johnson in
connection with the Acquisition shall be placed in escrow by SVG for purposes of
satisfying damages, losses, expenses and other similar charges which result from
breaches of the representations, warranties and covenants of Watkins-Johnson
contained herein.

        C.      In connection with the Acquisition, SVG and Watkins-Johnson
desire to make the representations, warranties, covenants and other agreements
set forth in this Agreement.

        NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,

                                 THE ACQUISITION

        1.1     The Purchase and Sale. At the Closing (as defined in Section
1.7) and subject to and upon the terms and conditions of this Agreement,
Watkins-Johnson shall, and shall cause the SEG Sub to, sell and deliver to SVG

<PAGE>   7

designated assignee) shall purchase from the SEG Sub all of the outstanding SEG
LLC Interests, and from Watkins-Johnson the Scotts Valley Property and all of
the outstanding shares of the International Subsidiary Capital Stock, in each
case free and clear of all Liens (but in the case of the Scotts Valley Property,
subject to such Liens as shall not adversely impact the use, value, ability to
finance, marketability, transferability, leasing, or development of the Scotts
Valley Property). Notwithstanding the foregoing, the shares of stock in the SEG
International Entities held by nominees of Watkins-Johnson or Watkins-Johnson
International in accordance with applicable law shall be transferred by such
nominees to nominees of SVG for nominal consideration equal to the original
consideration each such nominee paid to first acquire such shares.

        1.2     Consideration. In consideration for the sale of the SEG LLC
Interests, the Scotts Valley Property, and the SEG International Capital Stock,
SVG shall cause to be paid to Watkins-Johnson the Adjusted Consideration (as
defined below). At the Closing, SVG shall cause to be paid to Watkins-Johnson
or SEG Sub, by check or wire transfer, a cash payment (the "CLOSING CASH
PAYMENT") equal to $19,950,000. The total of the Closing Cash Payment plus the
Earnest Money Payment already made by SVG to Watkins-Johnson upon execution of
the Letter of Intent is herein referred to as the "ESTIMATED CONSIDERATION,"
which Estimated Consideration shall be subject to adjustment pursuant to
Sections 1.3 and 1.4 below. The Estimated Consideration as adjusted pursuant to
Sections 1.3 and 1.4 is herein referred to as the "ADJUSTED CONSIDERATION."

        1.3     Included Assets and Liabilities.

                (a)     Prior to the Closing, the SEG LLC and the SEG
International Entities shall hold all of the Included Assets and Included
Liabilities, except the Scotts Valley Property which is held by Watkins-Johnson.
Any Included Assets, except the Scotts Valley Property which will be held by
Watkins-Johnson immediately prior to the Closing, and Included Liabilities held
by Watkins-Johnson or the SEG Sub, or any affiliate of Watkins-Johnson or SEG
Sub not constituting an SEG International Entity, as of the date of this
Agreement, shall be transferred to the SEG LLC or an SEG International Entity
effective on or prior to the Closing.

                (b)     As used in this Agreement, the "INCLUDED ASSETS"
consists of all of the assets referenced on SCHEDULE 1.3 under the caption
"Included Assets" and explicitly excludes the "EXCLUDED ASSETS," which Excluded
Assets include the assets set forth on SCHEDULE 1.3 under the caption "Excluded
Assets." The "INCLUDED LIABILITIES" consists of all of the obligations and
liabilities referenced on SCHEDULE 1.3 under the caption "Included Liabilities"
and explicitly excludes all other liabilities and obligations, including the
Excluded Liabilities as referenced on SCHEDULE 1.3 under the caption "EXCLUDED
LIABILITIES." The parties agree and acknowledge that the lists of Excluded
Assets and Excluded Liabilities on SCHEDULE 1.3 are not intended to be, nor
shall be deemed to be, all inclusive.

                (c)     Notwithstanding anything in this Section 1.3 or in
Section 1.4, SVG may elect not to assume certain payables (the "UNASSUMED
PAYABLES") included in the Included Liabilities as of the Closing, in which case
the Included Liabilities as of the Closing shall not include such Unassumed
Payables for purposes of determining the Closing Net Assets pursuant to Section
1.4. In such event,



                                       -2-

<PAGE>   8

SVG shall advise Watkins-Johnson in writing of such Unassumed Payables on or
prior to the Closing, and shall pay to Watkins-Johnson at Closing the dollar
amount of such Unassumed Payables, which amounts shall be added to the Closing
Cash Payment, and Watkins-Johnson shall be liable to satisfy any such Unassumed
Payables.

        1.4     Post-Closing Adjustment.

                (a)     The parties acknowledge that the Estimated Consideration
was based upon the values for the Included Assets and the Included Liabilities
as of December 31, 1998, as adjusted, as set forth on SCHEDULE 1.4. The value of
Included Assets less the Included Liabilities as of December 31, 1998 of
$26,800,000 as set forth on SCHEDULE 1.4, is herein referred to as the
"PRELIMINARY NET ASSET VALUE." Within thirty (30) days after the Closing Date,
Watkins-Johnson shall deliver to SVG a certificate (the "CLOSING CERTIFICATE")
setting forth a schedule of and values for the Included Assets and Included
Liabilities (other than the Unassumed Payables), as of the Closing Date,
determined by Watkins-Johnson based on GAAP, which certificate shall be signed
by the President or Vice President of Watkins-Johnson. The Closing Certificate
shall also include a determination of the consolidated net assets being acquired
by SVG hereunder (the "CLOSING NET ASSET VALUE") of the Business, which shall be
equal to the value of the Included Assets minus the value of the Included
Liabilities (excluding the Unassumed Payables) as of the Closing Date, plus the
cash balances held by the SEG International Entities as of the Closing;
provided, however, that the value of the assets and liabilities, including the
equipment related to the AP Next product, set forth under the caption "Fixed
Valuation" on SCHEDULE 1.4 as of the Closing Date shall be equal to the value of
such assets and liabilities as of December 31, 1998; and, provided, further,
that the inventory balances (net of reserves) determined in accordance with GAAP
as of the Closing Date shall be increased by $4,500,000. In addition, in order
to determine the value of the Closing Net Assets, Watkins-Johnson shall,
immediately prior to the Closing or as soon as practicable thereafter, with the
reasonable assistance of SVG, perform a physical inspection and count of the
inventory and equipment included in the Included Assets to determine the value
of those assets as of the Closing Date. SVG shall observe the physical inventory
inspection and count.

                (b)     SVG shall have thirty (30) days from the date of receipt
of the Closing Certificate during which it may review the Closing Certificate.
Following completion of its review of the Closing Certificate, SVG shall deliver
to Watkins-Johnson a written notice (the "SVG CLOSING ADJUSTMENT NOTICE")
stating either (i) that SVG agrees with the calculation of the Closing Net Asset
Value set forth in the Closing Certificate or (ii) that SVG does not agree with
such calculation and providing SVG's calculation of the Closing Net Asset Value.
The parties shall in good faith attempt to resolve any differences between
Watkins-Johnson's calculation of Closing Net Asset Value and SVG's calculation
of Closing Net Asset Value. If the parties do not resolve any such differences
within thirty (30) days of the delivery of the SVG Closing Adjustment Notice,
the parties shall engage the independent accounting firm of
PricewaterhouseCoopers, LLP, or if PricewaterhouseCoopers LLP is unable to
perform such services, a mutually agreed upon independent accounting firm of
national standing and reputation, to determine the Closing Net Asset Value. Such
determination by the independent accounting firm shall be final and binding on
the parties. The cost of the services of the independent accounting firm shall
be



                                       -3-

<PAGE>   9

borne by the party whose determination of the Closing Net Asset Value is
furthest from the determination of the independent accounting firm, or if the
determination by such firm is equidistance from the parties' valuations, the
cost shall be split equally between the two parties. Each party shall cooperate
and shall use reasonable efforts to cause its officers, directors and employees
to cooperate with the other party and the independent accounting firm to
determine the Closing Net Asset Value in furnishing information, documents,
evidence and other assistance to the other party and the independent accounting
firm to facilitate the completion of the review and determination of the Closing
Net Asset Value. If the Closing Net Asset Value is less than the Preliminary Net
Asset Value, Watkins-Johnson shall pay SVG the difference in cash within ten
(10) business days after the final determination (whether by mutual agreement
between the parties or by the independent accounting firm) of the Closing Net
Asset Value. If the Closing Net Asset Value is greater than the Preliminary Net
Asset Value, SVG shall pay Watkins-Johnson the difference in cash within ten
(10) business days after the final determination (whether by mutual agreement
between the parties or by the independent accounting firm) of the Closing Net
Assets. In no event shall any amounts owed to SVG by Watkins-Johnson under this
Section 1.4(b) be paid out of the Escrow Fund.

        1.5     Escrow Fund. At the Closing, SVG shall deliver, or shall cause
to be delivered, directly to an escrow agent to be selected prior to Closing
(the "ESCROW AGENT"), an amount in cash equal to $3,450,000 (the "ESCROW
AMOUNT") to be deducted from the Closing Cash Payment and held in an escrow fund
pursuant to the terms set forth herein and in an escrow agreement to be entered
into by and among SVG, Watkins-Johnson and the Escrow Agent, substantially in
the form attached hereto as EXHIBIT A (the "ESCROW AGREEMENT"). Subject to the
terms of this Agreement, the Escrow Amount shall be available to satisfy any
indemnification obligations of Watkins-Johnson pursuant to Article 7 for Claims
made on or prior to the Escrow Release Date and shall be paid out as provided in
Section 7.5 hereof and in the Escrow Agreement.

        1.6     Environmental Package; Title Insurance and Survey. At the
Closing, for the convenience of Watkins-Johnson, SVG shall deliver, or shall
cause to be delivered, directly to the Environmental Consultant or the
Environmental Consultant's designee, an amount in cash equal to the amount
required to purchase the Environmental Package (the "ENVIRONMENTAL PACKAGE
COST"); provided, that the total Environmental Package Cost shall not exceed
$3,200,000. The parties hereto acknowledge that the Environmental Package Cost
(subject to the limitation set forth in the preceding sentence) is to be borne
by Watkins-Johnson and that SVG shall deduct the Environmental Package Cost from
the Closing Cash Payment. In addition, prior to the Closing, Watkins-Johnson
shall have obtained for the benefit of SVG or SVG's designee, as part of the
transfer of the Scotts Valley Property a CLTA Form 100 title insurance policy
(rev. 6/14/96) without a survey exception, insuring the Scotts Valley Property
for $14,500,000 (the "TITLE POLICY"). The Title Policy shall remain in full
force and effect after the Closing, for the benefit of SVG or a party or parties
designated by SVG before the Closing. Watkins-Johnson shall also obtain an ALTA
survey on the Scotts Valley Property. The cost of the Title Policy and a ALTA
survey on the Scotts Valley Property shall be shared equally by SVG and
Watkins-Johnson. All other costs associated with the transfer of the Scotts
Valley Property (including all closing costs and transfer taxes) shall be borne
by Watkins-Johnson. SVG agrees that any portion of the Environmental Package
Cost that is not paid to the Environmental Consultant (for example, any amounts
returned to SVG from any



                                       -4-

<PAGE>   10

escrow established with the Environmental Consultant) shall be applied to the
completion of the tasks and services required to be completed or performed by
the Environmental Consultant or, failing that, shall be returned to
Watkins-Johnson. SVG and Watkins-Johnson shall endeavor in good faith to work
out more specific arrangements regarding these matters by the Closing.

        1.7     Closing. Unless this Agreement is earlier terminated pursuant to
Section 8.1, the closing of the Acquisition (the "CLOSING") shall take place as
promptly as practicable, but not earlier than the later of (a) five (5) Business
Days following satisfaction or waiver of the conditions set forth in Article 6
and (b) the next month-end closing for Watkins-Johnson to occur, at the offices
of Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill
Road, Palo Alto, California 94304-1050, unless another place or time is agreed
to in writing by SVG and Watkins-Johnson. The date upon which the Closing
actually occurs is herein referred to as the "CLOSING DATE."

and warranties shall be effective as of the transfer of the Included Assets and
the Included liabilities held by Watkins-Johnson or the SEG Sub to the SEG LLC)
and as of the Closing Date as though made on the Closing Date as follows:

        2.1     Organization of Watkins-Johnson and the SEG Entities.

business and is in good standing in each jurisdiction where the character of the
properties owned, leased or operated by it or the nature of its activities makes

Business taken as a whole.

                (b)     SCHEDULE 2.1 contains a true and complete list of the
SEG Entities, indicating the jurisdiction of incorporation of each SEG Entity

Closing will be) duly executed and delivered by Watkins-Johnson and, assuming
the due authorization, execution and delivery by SVG, constitutes (or as of the
Closing will constitute) a valid and binding obligation of Watkins-Johnson,
enforceable in accordance with its terms, except as enforceability may be
limited by laws of general application relating to bankruptcy, insolvency and
the relief of debtors and rules of law governing specific performance,
injunctive relief or other equitable remedies. The execution and delivery of
this Agreement or any Related Agreement to be entered into by Watkins-Johnson
pursuant hereto does not, and the performance of this Agreement or any Related

Watkins-Johnson pursuant hereto will not, (i) Conflict with the Articles of
Incorporation or Bylaws of Watkins-Johnson or the equivalent organizational
documents of any of its subsidiaries, including the SEG Entities, (ii) subject
to the need to obtain the consents referenced in SCHEDULE 2.4, Conflict with any

Entities, pursuant to, any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation to which
Watkins-Johnson or any of its subsidiaries, including the SEG Entities, is a
party or by which Watkins-Johnson or any of its subsidiaries, including the SEG
Entities, or its or any of their respective properties is bound or affected.

        2.4     Consents. No consent, waiver, approval, order or authorization
of, or registration, declaration or filing with any court, administrative agency
or commission or other governmental authority or instrumentality, foreign or
domestic ("GOVERNMENTAL ENTITY") or any third party (so as not to trigger a
Conflict), is required by or with respect to Watkins-Johnson or any SEG Entity
in connection with the execution and delivery of this Agreement or any Related
Agreement or the consummation of the Acquisition by Watkins-Johnson, except for
such consents, approvals, orders, authorizations, registrations, declarations
and filings as may be required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"), and the antitrust laws of
any foreign country, and such other consents, approvals, orders, authorizations,
registrations, declarations and filings which if not obtained or made would not
be material to the ability of the parties to consummate the Acquisition.
SCHEDULE 2.4 sets forth all consents, waiver and approvals under any Contracts
or Leases to which Watkins-Johnson or any SEG Entity is a party or by which such
entity is bound required to be obtained in connection with the consummation of

the related unaudited statements of income for the three (3) month period then

Year-End Financials, the "SEG FINANCIALS"). The SEG Financials are fairly stated
and have been prepared in accordance with GAAP applied on a basis consistent
throughout the periods indicated and consistent with each other except as
specifically stated therein. The SEG Financials present fairly the consolidated
financial condition and operating results of SEG Sub as of the dates and during
the periods indicated therein, subject to normal year-end adjustments, which
will not be material in amount or significance.

required to be withheld, and (B) will have accrued on the SEG Financials all
Taxes attributable to the periods covered by the SEG Financials and will not

                        (iii)   The SEG Entities have not been, and will not be
prior to the Closing, delinquent in the payment of any Tax, nor is there any Tax
deficiency outstanding, assessed or proposed against the SEG Entities, nor have

                        (iv)    No audit or other examination of any Return of

accrued or reserved against in accordance



                                      -10-

                        (viii)  Watkins-Johnson has no knowledge of any Basis
for the assertion of any deficiency or claim for additional Taxes relating or
attributable to Taxes which, if adversely determined, would result in any Lien
on the Included Assets.

                        (ix)    None of the Included Assets is treated as
"tax-exempt use property," within the meaning of Section 168(h) of the Code.

                        (x)     None of the SEG Entities are, nor will any be on
or prior to the Closing, a party to any tax sharing, indemnification or
allocation agreement, nor does any SEG Entity owe any amount under any such
agreement.

                        (xi)    No adjustment relating to any Return of the SEG
Entities (or related to the Included Assets or the Business) has been proposed
formally or informally by any tax authority to Watkins-Johnson or any SEG Entity
or any representative thereof.

                        (xii)   SEG LLC will, prior to and as of the Closing,
constitute a limited liability company formed under Delaware law, SEG Sub has
been (and will be) the sole owner of SEG LLC at all times following its
formation, and neither Watkins-Johnson nor SEG Sub has taken (nor will take) any
action inconsistent with the treatment of SEG LLC as a "disregarded entity"
under Treas. Reg. Section 301.7701-3(b)(1)(ii).

                        (xiii)  The Included Assets transferred to SEG LLC by
SEG Sub constitute more than 80 percent of the tangible personal property held
or used in the course of the activities of SEG Sub requiring the SEG Sub to hold
a seller's permit for California sales tax purposes.

                (c)     Executive Compensation Tax. There is no contract,
agreement, plan or arrangement to which Watkins-Johnson or the SEG Entities are
a party as of the dates hereof, including but not limited to the provisions of
this Agreement, covering any employee or former employee of the SEG Entities (or
any SEG employees retained by SVG or an Affiliate of SVG following the Closing),
which, individually or collectively, could give rise to the payment of any
amount that if paid by SVG



                                      -11-

would not be deductible by SVG following the Closing (or would be subject to an
excise tax following the Closing) pursuant to Sections 280G, 404 or 162(m) of
the Code.

        2.9     Title to Properties; Absence of Liens and Encumbrances.

                (a)     SCHEDULE 2.9 sets forth: (i) a list of all real property

to each property listed on SCHEDULE 2.9:

                        (i)     as to property subject to a Lease, the Lease
(and, as to a sublease or other similar occupancy agreement, the master Lease)
is in full force and effect, is valid and effective in accordance with its
terms, and there is not, under such Lease or master Lease, any existing default
or event of default (or event which with notice or lapse of time, or both, would
constitute a default) by Watkins-Johnson or any SEG Entity, or to
Watkins-Johnson's knowledge, any other party thereto;

                        (ii)    as to property held subject to a Lease, upon
obtaining any required consents of the landlord, the Lease will continue to be
legal, valid, binding and enforceable against the SEG Entity that is a party
thereto and against the other party thereto, and will be in full force and
effect on identical terms following the consummation of the transactions
contemplated hereby;

                        (iii)   as to property subject to a Lease, to
Watkins-Johnson's knowledge, no third party to the Lease has repudiated any
provisions thereof;

                        (iv)    none of the SEG Entities has assigned,

any SEG Business Facilities, except as contemplated herein;

                        (v)     the SEG Business Facilities have received all
material approvals of Governmental Entities (including licenses and permits)
required in connection with the operation thereof as conducted by any SEG Entity
and have been operated and maintained in accordance with applicable laws, rules,
codes, ordinances, covenants, conditions and restrictions and regulations in all
material respects, except to the extent that any such violation would neither
have a Material Adverse Effect on the SEG Entities and the Business taken as a
whole, the Included Assets or the Included Liabilities, nor prevent the
consummation of the transactions contemplated hereunder; and

                        (vi)    all SEG Business Facilities are supplied with
utilities and other services necessary for the operation of said facilities.

<PAGE>   18

                (b)     The SEG Entities have good, valid and marketable title
to, or, in the case of leased properties and assets, valid leasehold interests
in, all of the tangible properties and assets, real, personal and mixed, used in
the Business, including the Included Assets, free and clear of any Lien, except
for the Japanese Loans and any Lien which would not have an adverse impact on
the use, value, ability to finance, transferability, leasing, development or
marketability of such assets. The Included Assets are all those assets necessary
and sufficient for the operation of the Business as presently conducted.

                (c)     All material items of equipment owned or leased by any
SEG Entity used in the Business (the "EQUIPMENT") are in good operating
condition, regularly and properly maintained, subject to normal wear and tear.

                (d)     (i) there are no structural, electrical, mechanical,
plumbing, roof, paving or other defects in any improvements located on any SEG
Business Facilities as could, either individually or in the aggregate, have a
Material Adverse Effect on any SEG Entity and the Business taken as a whole,
(ii) there are no natural or artificial conditions upon any SEG Business
Facilities or any other facts or conditions which could, in the aggregate,
materially and adversely effect the transferability, ability to finance,
ownership, leasing, use, development, occupancy or operation of any such real
property, (iii) neither Watkins-Johnson nor the SEG Entities have received any
notice from any insurance company of any defects or inadequacies in any SEG
Business Facility or any part thereof which could materially and adversely
affect the insurability of such property or the premiums for the insurance
thereof, nor has any notice been given by any insurer of any such property
requesting the performance of any repairs, alterations or other work with which
compliance has not been made, (iv) there are no parties in possession of any
portion of any SEG Business Facilities, whether as tenants, trespassers or
otherwise, except the SEG Entities, (v) there currently exists water, sewer,
gas, electrical, telephone and telecommunication lines and surface drainage
systems serving each SEG Business Facility which have been licensed, permitted,
completed, installed and paid for and which are sufficient as licensed and
permitted to service the operations of each such property when fully occupied
and operational, and all such lines and systems serving each such property are
located in the right-of-way of public roadways to the boundary of the land on
which each such property is situated, and (vi) on the Closing Date there will be
no outstanding written or oral contracts made by Watkins-Johnson or any SEG
Entity for any alterations or improvements on or to any SEG Business Facility,
which have not been fully paid, and Watkins-Johnson shall cause to be discharged
all mechanics' and materialmen's liens arising from any labor or materials
provided to, for, or at the request of Watkins-Johnson or any SEG Entity and
furnished to such facility or facilities prior to the Closing Date.

        2.10    Intellectual Property.

                (a)     SCHEDULE 2.10(A) lists all Registered Intellectual
Property owned by, filed in the name of, assigned to or applied for by each SEG
Entity or Watkins-Johnson and related to the Business (the "SEG REGISTERED
INTELLECTUAL PROPERTY") and lists any proceedings or actions before any court or
tribunal (including the PTO or equivalent authority anywhere in the world)
related to any of the SEG Registered Intellectual Property or SEG Intellectual
Property and to which any SEG Entity or Watkins-Johnson is a party or of which
Watkins-Johnson has knowledge.



                                      -13-
<PAGE>   19

                (b)     As of the Closing, one or more of the SEG Entities: (i)
will be the exclusive owners of all Trademarks used in connection with the
operation or conduct of the Business, and (ii) will own exclusively, and have
good title to, all copyrighted works that are software or other products of the
SEG Entities or other works of authorship that any of the SEG Entities otherwise
purport to own.

                (c)     Each item of SEG Intellectual Property, including all
SEG Registered Intellectual Property listed in SCHEDULE 2.10(A), and, to
Watkins-Johnson's knowledge all Intellectual Property licensed to an SEG Entity
by another Person, are free and clear of any Liens. As of the Closing, all SEG
Intellectual Property will be owned exclusively by an SEG Entity and none of the
SEG Entities will have (i) transferred ownership of, or (ii) authorized the
retention of any exclusive rights to use or joint ownership of, or (iii) except
pursuant to the licenses described in SCHEDULE 2.10(J), granted any license or
right to use, any Intellectual Property that is or was SEG Intellectual
Property, to any Person other than an SEG Entity. The Included Assets include
all SEG Intellectual Property.

                (d)     The consummation of the transactions contemplated by
this Agreement will not cause or obligate SVG or any SEG Entity (i) to grant to
any third party any rights or licenses with respect to any Intellectual
Property, or (ii) pay any royalties or other amounts in excess of those being
paid by any SEG Entity prior to the Closing.

                (e)     The consummation of the transactions contemplated by
this Agreement will not result in the loss of, or otherwise adversely affect,
any ownership rights of any SEG Entity in any SEG Intellectual Property or
result in the breach or termination of any license, contract or agreement
required to be disclosed on SCHEDULE 2.10(I) or SCHEDULE 2.10(J).

                (f)     To the extent that any Intellectual Property has been
developed or created independently or jointly by any Person other than an SEG
Entity for which such SEG Entity has, directly or indirectly, paid, an SEG
Entity has a written agreement with such Person with respect thereto, and
thereby has irrevocably obtained worldwide, perpetual ownership of, and is the
exclusive owner of, all such Intellectual Property and all Intellectual Property
associated therewith, including the right to seek past and future damages with
respect thereto by operation of law or by valid assignment; and has received the
waiver of all such Persons with respect thereto of all non-assignable rights
including but not limited to all author or moral rights. All such agreements are
listed on SCHEDULE 2.10(F) hereto.

                (g)     None of the SEG Intellectual Property was developed by
or on behalf of or using grants of any Governmental Entity.

                (h)     At Closing, the SEG LLC will own all Intellectual
Property of Watkins-Johnson and the SEG Entities related to the Field. The SEG
Intellectual Property and the Intellectual Property licensed to the SEG Entities
pursuant to the licenses described on SCHEDULE 2.10(J) will constitute as of the
Closing all the Intellectual Property used in and/or necessary to the conduct of
the Business as it was conducted during the one (1) year period prior to the
date of this Agreement, or as it currently is being conducted, or, to the
knowledge of Watkins-Johnson with respect to the products, processes and
components of the SEG Entities which are currently under development and are
listed on



                                      -14-
<PAGE>   20

SCHEDULE 2.10(h), as they are planned or contemplated to be conducted in the one
(1) year period commencing on the Closing Date, including (i) the making, using,
selling, marketing, or importing of any product or device, (ii) the practice of
any process, (iii) the offering or performance of any service, or (iv) the
copying, display, performance, distribution, creation of derivative works of, or
the exploitation of any device or work (collectively, the "BUSINESS
ACTIVITIES"). All Intellectual Property used by the SEG Entities in connection
with the Business which was (i) developed by or is owned by Watkins- Johnson, or
(ii) which is directly licensed to Watkins-Johnson by any Person other than an
SEG Entity and which is not licensed directly by such Person to an SEG Entity,
is the subject of a written license or sublicense agreement with an SEG Entity
disclosed on SCHEDULE 2.10(J) that grants an SEG Entity the right to use any
such Intellectual Property.

                (i)     The contracts, licenses and agreements listed in
SCHEDULE 2.10(I) include all contracts, licenses and agreements pursuant to
which any SEG Entity has licensed any Intellectual Property to any Person.
Watkins-Johnson has provided true and correct copies of all such agreements, as
amended, to SVG. No SEG Entity is in breach of, nor has any SEG Entity failed to
perform under any of the foregoing contracts, licenses and agreements and, to
the knowledge of Watkins-Johnson, no other party to any such contract, license
or agreement is in breach of or has failed to perform thereunder.

                (j)     Other than inbound "shrink-wrap" and similar publicly
available commercial binary code end-user licenses, the contracts, licenses and
agreements listed in SCHEDULE 2.10(J) include all contracts, licenses and
agreements pursuant to which any Person has licensed any Intellectual Property
to any SEG Entity. Watkins-Johnson has provided true and correct copies of all
such agreements, as amended, to SVG. No SEG Entity is in breach of, nor has any
SEG Entity failed to perform under any of the foregoing contracts, licenses and
agreements and, to the knowledge of Watkins-Johnson, no other party to any such
contract, license or agreement is in breach of or has failed to perform
thereunder. No Person who has licensed Intellectual Property to any SEG Entity
has ownership rights or license rights to improvements made by such SEG Entity
in such Intellectual Property.

                (k)     SCHEDULE 2.10(K) lists all currently effective
contracts, licenses and agreements pursuant to which any SEG Entity has agreed
to, or assumed, any obligation or duty to warrant, indemnify, reimburse, hold
harmless, guaranty or otherwise assume or incur any obligation or liability for
any losses, costs, or damages of any Person with respect to any Intellectual
Property or product or service of any SEG Entity.

                (l)     None of the SEG Entities has infringed or
misappropriated any Intellectual Property of any other Person or taken any
action that would constitute unfair competition or trade practices under the
laws of any jurisdiction. Following the Closing, none of the activities of the
Business when conducted by SVG or the SEG Entities in substantially the same
manner as it currently is conducted or is contemplated to be conducted,
including but not limited to all Business Activities of the SEG Entities, will
infringe or misappropriate any Intellectual Property of any Person (including
but not limited to Watkins-Johnson), or constitute unfair competition or trade
practices under the laws of any jurisdiction. None of Watkins-Johnson nor any
SEG Entity has received written notice from any Person



                                      -15-
<PAGE>   21

claiming that any SEG Entity has infringed or misappropriated or is infringing
or misappropriating any Intellectual Property of any Person or has taken any act
that constitutes unfair competition or trade practices under the laws of any
jurisdiction (nor does Watkins-Johnson or any SEG Entity have knowledge of any
Basis therefor).

                (m)     Each item of SEG Registered Intellectual Property is
valid and subsisting (it being understood that the reference to validity is not
intended to constitute a representation relating to whether or not the
Intellectual Property in question infringes another Person's Intellectual
Property), and all necessary registration, maintenance and renewal fees in
connection with each such item have been paid and all necessary documents and
certificates in connection with such SEG Registered Intellectual Property have
been filed with the relevant patent, copyright, trademark or other authorities
in the United States and the foreign jurisdiction in which Watkins-Johnson or an
SEG Entity has chosen to file, for the purposes of maintaining such Registered
Intellectual Property. There are no actions that must be taken by
Watkins-Johnson or any SEG Entity within ninety (90) days of the Closing Date,
including the payment of any registration, maintenance or renewal fees or the
filing of any responses to PTO office actions, documents, applications or
certificates for the purposes of maintaining, perfecting or preserving or
renewing any SEG Registered Intellectual Property. For any SEG Intellectual
Property and each product or service of any SEG Entity that constitutes or
includes a copyrightable work or Mask Work, such SEG Entity has registered the
copyright in the latest version of such work with relevant Governmental
Entities, including the U.S. Copyright Office. In each case in which an SEG
Entity has acquired any Intellectual Property from any Person, such SEG Entity
has obtained a valid and enforceable assignment sufficient to irrevocably
transfer all rights in such Intellectual Property (including the right to seek
past and future damages with respect thereto) to such SEG Entity and, to the
maximum extent provided for by, and in accordance with, applicable laws and
regulations, such SEG Entity has filed each such assignment with the relevant
Governmental Entity, including the PTO, the U.S. Copyright Office, or their
respective equivalents in any relevant foreign jurisdiction, as the case may be.
No SEG Entity has claimed "Small Entity" status or other particular status in
the application for registration of any Intellectual Property, which claim of
status was not at the time made, or which has since become, inaccurate or false
or that will no longer be true and accurate as a result of the transactions
contemplated hereunder.

                (n)     There are no contracts, licenses or agreements between
any SEG Entity and any other Person or between Watkins-Johnson and any other
Person with respect to SEG Intellectual Property under which any SEG Entity or
Watkins-Johnson has given or received any written notice of any dispute
regarding the scope of such agreement, or performance under such agreement
including with respect to any payments to be made or received by any SEG Entity
thereunder.

                (o)     To Watkins-Johnson's knowledge, no Person is infringing
or misappropriating any SEG Intellectual Property. None of the SEG Entities or
Watkins-Johnson has made or asserted, or to Watkins-Johnson's knowledge, has at
any time in the past had any Basis for asserting, any claim of violation or
infringement of any SEG Intellectual Property.



                                      -16-
<PAGE>   22

                (p)     Each SEG Entity has taken all steps reasonable under the
circumstances to protect the confidentiality and trade secret status of any
material confidential information of such SEG Entity and knows of no Basis on
which it could be claimed that an SEG Entity has failed to protect the
confidentiality of its material confidential information or failed to protect
any confidential information of any Person other than an SEG Entity to the
fullest extent required by any agreement or other arrangement by which such SEG
Entity is or was bound and which relates to such information .

                (q)     All current and former employees, consultants and
contractors of the SEG Entities have entered into a valid and binding written
agreement with an SEG Entity sufficient to vest title in such SEG Entity of all
Intellectual Property created by such employee, consultant or contractor in the
scope of his, her or its employment or relationship with such SEG Entity.

                (r)     No SEG Intellectual Property or product, service or
Business Activity of any SEG Entity is subject to any proceeding or outstanding
decree, order, judgment or settlement agreement or stipulation to which
Watkins-Johnson or any SEG Entity is a party or of which Watkins-Johnson or any
SEG Entity has knowledge that restricts in any manner the use, transfer or
licensing thereof by any SEG Entity or may affect the validity, use or
enforceability of such SEG Intellectual Property.

                (s)     No (i) product, service or publication of an SEG Entity,
(ii) material published or distributed by an SEG Entity, or (iii) conduct or
statement of an SEG Entity constitutes obscene material, a defamatory statement
or false advertising or otherwise violates any similar applicable law or
regulation.

                (t)     To the extent used in accordance with their intended
purpose as set forth in any manuals or materials (as amended or supplemented)
delivered in connection therewith, all of the products, as upgraded, of the SEG
Entities (including products currently under development) will accurately
record, store, process, calculate and present calendar dates falling on and
after (and if applicable, spans of time including) January 1, 2000, and will
accurately calculate any information dependent on or relating to such dates in
the same manner, and with the same functionality, data integrity and
performance, as such products record, store, process, calculate and present
calendar dates on or before December 31, 1999, or calculate any information
dependent on or relating to such dates (collectively, "YEAR 2000 COMPLIANT").
All of the products of each SEG Entity (i) will lose no functionality with
respect to the introduction of records containing dates falling on or after
January 1, 2000 and (ii) will be operable without error with other products used
and distributed by SVG that may deliver records to the products of such SEG
Entity or receive records from the products of each SEG Entity, or interact with
the products, including but not limited to back-up and archived data, provided
that such other products are also Year 2000 Compliant. Set forth on SCHEDULE
2.10(T) is a true and correct statement of the extent to which the internal
computer and technology products and systems of each SEG Entity are Year 2000
Compliant. Watkins-Johnson has taken all actions represented in such statement
to have been taken by it.



                                      -17-
<PAGE>   23

                (u)     All SEG Intellectual Property will be fully
transferable, alienable or licensable by the SEG Entity owning such Intellectual
Property or SVG after Closing without restriction and without payment of any
kind to any third party.

                (v)     Watkins-Johnson has no knowledge of any facts or
circumstances that would render any SEG Intellectual Property invalid or
unenforceable. Without limiting the foregoing, Watkins-Johnson does not know of
any information, materials, facts, or circumstances, including any information
or fact that would constitute prior art, that would render any of the SEG
Registered Intellectual Property invalid or unenforceable, or would adversely
affect any pending application for any SEG Registered Intellectual Property and
none of Watkins-Johnson nor any SEG Entity has misrepresented, or failed to
disclose, or has any knowledge of any misrepresentation or failure to disclose,
any fact or circumstance in any application for any SEG Registered Intellectual
Property that would constitute fraud or a misrepresentation with respect to such
application or that would otherwise affect the validity or enforceability of any
SEG Intellectual Property.

                (w)     None of the Intellectual Property sold to Applied
Materials, Inc. by Watkins-Johnson or the SEG Sub is necessary to, or would be
infringed by any operations of the SEG Entities in the Field.

                (x)     At the Closing, as between Watkins-Johnson and the SEG
LLC, all Intellectual Property related to the Field will be owned by the SEG
LLC.

                (y)     Watkins-Johnson has not entered into any "Additional
Agreements" with Semiconductor Leading Edge Technologies, Inc. (as such term is
defined in the agreements between Watkins-Johnson and such company which are
disclosed in Watkins-Johnson's Disclosure Schedules).

                (z)     Except for the licenses granted by Watkins-Johnson in
the "Applied Transaction Agreements" (as such term is defined in Schedule 1.3),
neither Watkins-Johnson nor any SEG Entity has granted to Applied Materials,
Inc. any licenses to or any other rights to or under any of the agreements
described in SCHEDULES 2.10(I) and 2.10(J).

        2.11    Permits; Compliance; Restrictions.

                (a)     The SEG Entities hold all material permits, licenses,
variances, exemptions, orders and approvals from Governmental Entities required
for the operation of the Business (collectively, the "SEG PERMITS"). The SEG
Entities are in material compliance with the terms of the SEG Permits.

                (b)     None of the SEG Entities is in conflict with, or in
default or violation of (i) any law, rule, regulation, order, judgment or decree
applicable to any SEG Entity or by which any SEG Entity or any of their
respective properties is bound or affected, or (ii) any material note, bond,
mortgage, indenture, contract, agreement, lease, license, SEG Permit, franchise
or other instrument or obligation to which any SEG Entity is a party or by which
any SEG Entity or its or any of their respective properties is bound or
affected. No investigation or review by any Governmental Entity is pending or,
to



                                      -18-
<PAGE>   24

Watkins-Johnson's knowledge, threatened against any SEG Entity, nor has any
Governmental Entity indicated an intention to conduct the same.

                (c)     There is no agreement (noncompete or otherwise),
commitment, judgment, injunction, order or decree to which any SEG Entity is a
party or otherwise binding upon any SEG Entity which has or may have the effect
of prohibiting or impairing any business practice of the SEG Entities, any
acquisition of property (tangible or intangible) by any SEG Entity or the
conduct of the Business. No SEG Entity has entered into any agreement under
which any SEG Entity is restricted from selling, licensing, distributing or
otherwise exploiting any of the SEG Intellectual Property or products to or
providing services to, customers or potential customers or any class of
customers, in any geographic area during any period of time or in any segment of
the market.

        2.12    Litigation. There is no action, suit, proceeding, claim,
arbitration or investigation pending against any SEG Entity or with respect to
the Business, or as to which Watkins-Johnson or any SEG Entity has received any
notice of assertion nor, to Watkins-Johnson's knowledge, is there a threatened
action, suit, proceeding, claim, arbitration or investigation against any SEG
Entity or with respect to the Business. None of Watkins-Johnson or any SEG
Entity is aware of any Basis for any action, suit, proceeding, claim,
arbitration or proceeding of the type described in the preceding sentence, nor
do any of them have any knowledge of any unasserted claim, the assertion of
which is likely, and which, if asserted, will seek damages, an injunction or
other legal, equitable, monetary or nonmonetary relief against any SEG Entity.
To Watkins-Johnson's knowledge, no Governmental Entity has at any time
challenged or questioned the legal right of the SEG Entities to manufacture,
offer or sell any of their products in the present manner or style thereof.

        2.13    Brokers' and Finders' Fees. Watkins-Johnson has not incurred,
nor will it incur, directly or indirectly, any liability for brokerage or
finders' fees or agents' commissions or any similar charges in connection with
this Agreement or any transaction contemplated hereby.

        2.14    Employee Benefit Plans.

                (a)     The SCHEDULE 2.14 contains an accurate and complete list
of each material plan, program, policy, practice, contract, agreement or other
arrangement providing for compensation (including consulting fees), severance,
termination pay, performance awards, stock or stock-related awards, fringe
benefits or other employee benefits or remuneration of any kind, whether formal
or informal, written or otherwise, funded or unfunded and whether or not legally
binding, including without limitation, each "employee benefit plan" within the
meaning of Section 3(3) of ERISA, which is or has been maintained, contributed
to, or required to be contributed to (i) by any SEG Entity, (ii) by Watkins-
Johnson for the benefit of any SEG Entity, (iii) by Watkins-Johnson or (iv) any
trade or business which is under common control with Watkins-Johnson within the
meaning of Section 414 of the Code (an "ERISA AFFILIATE") for the benefit of any
current, former, or retired employee, officer, or director of Watkins-Johnson or
any ERISA Affiliate whose principal responsibilities are to provide services to
any SEG Entity (the "SEG EMPLOYEE PLANS"), together with a schedule of all
liabilities, whether or not accrued, under each such SEG Employee Plan. None of
Watkins-Johnson nor any SEG Entity has a plan



                                      -19-
<PAGE>   25

or commitment, whether legally binding or not, to establish any new SEG Employee

retired employee of any SEG Entity.

                (j)     No SEG Entity has granted (i) any stock options for
shares of such SEG Entity or (ii) any stock in such SEG Entity for compensatory
purposes.

        2.15    Employees; Labor Matters. To Watkins-Johnson's knowledge, no
employee of any SEG Entity (i) is in violation of any term of any employment
contract, patent disclosure agreement, non-competition agreement, or any
restrictive covenant to a former employer relating to the right of any such
employee to be employed by such SEG Entity because of the nature of the business
conducted or presently proposed to be conducted by such SEG Entity or to the use
of trade secrets or proprietary information of others and (ii) has given written
notice of his or her intention to not provide services to any SEG Entity after
the Closing Date. To Watkins-Johnson's knowledge, there are no activities or
proceedings of any labor union to organize any employees of any SEG Entity and
there are no strikes, or material slowdowns, work stoppages or lockouts, or
threats thereof by or with respect to any employees of any SEG Entity or any of
its subsidiaries. No SEG Entity is, nor has it ever been, a party to any
collective bargaining agreement. Each SEG Entity is and has been in material
compliance with all applicable laws regarding employment practices, terms and
conditions of employment, and wages and hours (including, without limitation,
ERISA, WARN or any similar state or local law).

        2.16    Environmental Matters.

                (a)     (i)     Hazardous Material. No amount of any substance
that has been designated by any Governmental Entity or by applicable federal,
state, foreign or local law to be radioactive, toxic, hazardous or otherwise a
danger to health or the environment, including, without limitation, PCBs,
asbestos, petroleum, products or any fraction thereof urea-formaldehyde and all
substances listed as hazardous substances pursuant to the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended, or
defined as a hazardous waste pursuant to the Resource Conservation and Recovery
Act of 1976, as amended, and the regulations promulgated pursuant to said laws
(a "HAZARDOUS MATERIAL"), but excluding office and janitorial supplies, are
present, as a result of the actions of any SEG Entity or any Affiliate of any
SEG Entity, or, to Watkins-Johnson's knowledge, as a result of any actions of
any third party or otherwise, in, on or under any property, including the land
and the improvements, ground water and surface water thereof, that any SEG
Entity has at any time owned, operated, occupied or leased ("HISTORIC SEG
BUSINESS FACILITIES") except as would not be a violation of any Environmental
Laws. All of the Historic SEG Business Facilities are accurately described in
SCHEDULE 2.16.

                        (ii)    Environmental Liabilities. No action,
proceeding, revocation proceeding, amendment procedure, writ, injunction or
Claim is pending, or, to Watkins-Johnson's knowledge, threatened concerning any
SEG Environmental Permit, Hazardous Material or any Hazardous Materials Activity
of any SEG Entity. Watkins-Johnson is not aware of any fact or circumstance
which could involve any SEG Entity in any environmental litigation or impose
upon any SEG Entity any material environmental liability.



                                      -22-
<PAGE>   28


                        (iii)   USTs, Asbestos and PCBs. To Watkins-Johnson's
knowledge, there are no underground storage tanks, asbestos which is friable or
likely to become friable or PCBs present on any SEG Business Facility.

                        (iv)    Hazardous Materials Activities. Watkins-Johnson
and the SEG Entities have conducted all Hazardous Material Activities relating
to the Business in compliance in all material respects with all applicable
Environmental Laws. To Watkins-Johnson's knowledge, the Hazardous Materials
Activities of the Watkins-Johnson and the SEG Entities with respect to the
Business prior to the Closing have not resulted in the exposure of any person to
a Hazardous Material in a manner which has caused or could reasonably be
expected to cause an adverse health effect to any such person.

                (b)     Permits: SCHEDULE 2.16 accurately describes all of the
environmental permits currently held by Watkins-Johnson or any SEG Entity for
the Business or the operation of the SEG Business Facilities ("SEG ENVIRONMENTAL
PERMITS") and the listed SEG Environmental Permits are all of the environmental
permits necessary for the continued conduct of any Hazardous Material Activity
of Watkins-Johnson and the SEG Entities relating to the Business as such
activities are currently being conducted. All such SEG Environmental Permits are
valid and in full force and effect. Watkins-Johnson and the SEG Entities have
complied in all material respects with all covenants and conditions of any SEG
Environmental Permit which is or has been in force with respect to the Hazardous
Materials Activities of the Business. No circumstances exist which could cause
any SEG Environmental Permit to be revoked, modified, or rendered non-renewable
upon payment of the permit fee. All SEG Environmental Permits and all other
consents and clearances required by any Environmental Law or any agreement to
which either Watkins-Johnson or any SEG Entity is bound as a condition to the
performance and enforcement of this Agreement have been obtained or will be
obtained prior to the Closing at no cost to SVG.

                (c)     Offsite Hazardous Material Disposal. With respect to the
operation of the Business, Watkins-Johnson and the SEG Entities have transferred
or released Hazardous Materials only to those Disposal Sites set forth in
SCHEDULE 2.16; and, to Watkins-Johnson's knowledge, no action, proceeding,
liability or claim exists or is threatened against any Disposal Site or against
Watkins-Johnson or any SEG Entities with respect to any transfer or release of
Hazardous Materials relating to the Business to a Disposal Site which could
reasonably be expected to subject any SEG Entity to liability.

                (d)     Reports and Records. Watkins-Johnson and the SEG
Entities have delivered to SVG or made available for inspection by SVG and its
agents, representatives and employees all records in Watkins-Johnson's and any
SEG Entity's possession concerning the Hazardous Materials Activities relating
to the Business and all environmental audits and environmental assessments of
any Historic SEG Business Facility conducted at the request of, or otherwise in
the possession of the Watkins-Johnson or any SEG Entity. Watkins-Johnson and the
SEG Entities have complied with all environmental disclosure obligations imposed
by applicable law with respect to this transaction.

                (r)     any other agreement, contract or commitment that

        Watkins-Johnson has delivered to SVG a correct and complete copy of each
written contract listed on SCHEDULE 2.17 and SCHEDULE 2.10 and a written summary
setting forth the terms and conditions of each oral agreement referred to on
SCHEDULE 2.17. The SEG Entity that is a party thereto is in compliance with and
has not breached, violated or defaulted under, or received notice that it has
breached, violated or defaulted under, any of the terms or conditions of any
agreement, contract, covenant, instrument, lease, license or commitment to which
it is a party or by which it is bound (each a "CONTRACT"), nor is
Watkins-Johnson aware of any event that would constitute such a breach,
violation or default with the lapse of time, giving of notice or both. Each
Contract is in full force and effect and, to Watkins-Johnson's knowledge, is not
subject to any default thereunder by any third party obligated pursuant thereto.
Following the Closing, subject to the need to obtain the consents and approvals
referenced in SCHEDULE 2.4, SVG or an SEG Entity will be permitted to exercise
all or any SEG Entity's rights under the Contracts without the payment of any
additional amounts or consideration other than ongoing fees, royalties or

transaction contemplated by this Agreement not occurred.

country by any SEG Entity ("IMPORTED GOODS") have been properly valued and
classified in accordance with applicable tariff laws, rules and regulations, and
all proper duties, tariffs or excise taxes have been paid with respect to the
Imported Goods. No penalties have been assessed, asserted or claimed with
respect to any Imported Goods. All Imported Goods have been properly marked as
to country of origin, content and material.

        2.19    Customers and Suppliers.

                (a)     SCHEDULE 2.19(A)(I) sets forth a complete and accurate
list of the customers of the Business who have purchased product from the SEG
Entities or Watkins-Johnson during the prior fiscal year or any interim period

material limitation of, or any material modification or material change to the
configuration of, orders contained in outstanding backlog

contain a reasonably accurate summary of all meetings of the Board of Directors
(or committees thereof) of each of the SEG Entities and their stockholders, or
actions by written consent, since the time of incorporation or formation of each
such SEG Entity, as the case may be, and have been maintained in accordance with
applicable sound business practices, laws and other requirements. Prior to the
Closing, the stock ledger (if any) of each of the SEG Entities shall have been
made available to SVG and shall be complete and reflects all issuances,
transfers, repurchases and cancellations of equity securities of such SEG
Entity.

        2.21    No Illegal Payments, Etc. None of the SEG Entities (nor any of
its officers, employees, agents or Affiliates) has: (a) directly or indirectly
given or agreed to give any illegal gift, contribution, payment or similar
benefit to any supplier, customer, governmental official or employee or other
person who was or is in a position to help or hinder its business (or assist in
connection with any actual transaction) or made or agreed to make any illegal
contribution, or reimbursed any illegal political gift or contribution made by
any other person, to any candidate for federal, state, local or foreign public

aggregate, an adverse impact on any SEG Entity, or (b) established or maintained
any unrecorded fund or asset or made any false entries on any books or records
for any purpose.

manufactured, sold, leased, or delivered by the SEG Entities has been in
conformity with all applicable contractual commitments and all express and
implied warranties, and none of the SEG Entities has any Liability (and, to
Watkins- Johnson's knowledge, there is no Basis for any present or future
action, suit, proceeding, hearing, investigation, charge, complaint, claim, or
demand against it giving rise to any Liability) for replacement or repair
thereof or other damages in connection therewith, subject in all respects to,
and only to, the reserve for product warranty claims set forth on the face of
the SEG Balance Sheet subject to changes in the ordinary course of business
consistent with past practices from the date of the SEG Balance Sheet. The
provision for warranties as of December 31, 1998, as shown on SCHEDULE 1.4 was,
and such provision as shown on the Closing Certificate will be as of the
Closing, determined in accordance with GAAP. No product manufactured, sold,
leased, or delivered by any SEG Entity is subject to any guaranty, warranty, or
other indemnity beyond the applicable standard terms and conditions of sale or

Watkins-Johnson Disclosure Schedules or certificate furnished by Watkins-Johnson
at the Closing pursuant to this Agreement, contains or will contain, any untrue
statement of a material fact, or omits or will omit to state any material fact
necessary in order to make the statements contained herein or therein, in the
light of the circumstances under which made, not misleading.

        4.2     No Solicitation.

                (a)     From and after the date of this Agreement until the
earlier of the Closing or termination of this Agreement pursuant to its terms,
Watkins-Johnson and its subsidiaries shall not (nor will it permit any of its
officers, directors, members, shareholders, agents, representatives or
Affiliates to), directly or indirectly, take any of the following actions with
any party other than SVG and its designees: (i) solicit, encourage, initiate or
participate in any negotiations or discussions with respect to any offer or
proposal to acquire all or any portion of the Business, or any portion of the
capital stock of any SEG Entity whether by merger, purchase of assets, tender
offer or otherwise, or effect any such transaction, (ii) disclose any
information not customarily disclosed to any Person concerning the Business or
afford to any Person access to its properties, books or records as they pertain
to the Business, (iii) assist or cooperate with any Person to make any proposal
to purchase all or any part of capital stock of any SEG Entity or any assets of
the Business, other than inventory in the ordinary course of business, or (iv)
enter into any agreement with any Person providing for the acquisition of the
Business (whether by way of merger, purchase of assets, or otherwise). In the
event Watkins-Johnson shall receive any offer or proposal, directly or
indirectly, of the type referred to in clause (i) or (iii) above, or any request
for disclosure or access pursuant to clause (ii) above, it shall immediately
inform SVG as to any such offer or proposal and will cooperate with SVG by
furnishing any information about the offer or proposal it may reasonably
request. However, if that offer or proposal would also include the acquisition,
whether directly or indirectly, of any part of Watkins-Johnson's business or
assets in addition to the Business, Watkins-Johnson shall inform the Chairman
and Chief Executive Officer of SVG, and SVG shall cause that officer not to
disclose the fact of that offer or proposal to any other Person (whether within
or without SVG) and not to use the fact of that offer or proposal or any
information communicated regarding that offer or proposal for any purpose other
than in connection with the acquisition of the



                                      -30-
<PAGE>   36

Business (and only the Business) by SVG. During the period referenced in the
first sentence of this Section 4.2(a), any proposal or offer that
Watkins-Johnson makes regarding the acquisition of Watkins- Johnson itself shall
clarify that Watkins-Johnson has entered into any agreement to sell the Business
and Watkins-Johnson is bound by the exclusivity provision set forth in this
Section 4.2, and shall specifically exclude the Business from any discussions
with third parties concerning such offer or proposal. Notwithstanding anything
to the contrary in this Agreement, nothing in this Agreement shall restrict the
ability of Watkins-Johnson to conduct any of the aforementioned actions with
respect to the acquisition or possible acquisition of Watkins-Johnson (whether
by way or merger, purchase of capital stock, purchase of assets, tender offer or
otherwise) unless such acquisition or possible acquisition will prevent
Watkins-Johnson from consummating the transactions contemplated hereby;
provided, however, that if Watkins-Johnson is acquired by a third party, such
acquiror shall agree and acknowledge without exception that such acquisition
shall in no manner diminish or otherwise affect the obligations of
Watkins-Johnson hereunder or under the Escrow Agreement.

                (b)     Notwithstanding anything to the contrary in this Section
4.2, Watkins-Johnson will not provide any non-public information to a third
party unless: (i) Watkins-Johnson provides such non-public information about the
Business or the SEG Entities pursuant to a nondisclosure agreement with terms
regarding the protection of confidential information at least as restrictive as
such terms in the Confidentiality Agreement; and (ii) such non-public
information has been or is delivered to SVG.

                              ADDITIONAL AGREEMENTS

        5.1     Confidentiality; Access to Information.

                (a)     Confidentiality Agreement. The parties acknowledge that
Watkins-Johnson and SVG have previously executed a Confidentiality Agreement
dated as of July 29, 1998 (the "CONFIDENTIALITY AGREEMENT"), which
Confidentiality Agreement will continue in full force and effect in accordance
with its terms.

                (b)     Access to Information. Watkins-Johnson will afford SVG
and its accountants, counsel and other representatives reasonable access during
normal business hours to the properties, books, records and personnel of the SEG
Entities during the period prior to the Closing Date, and shall assist SVG, in
obtaining all information concerning the Business, including the status of
product development efforts, properties, results of operations and personnel of
the SEG Entities, as SVG may reasonably request. SVG shall be permitted
reasonable access to SEG Business Facilities for the purpose of performing such
investigations of the condition of such facilities as SVG deems necessary,
including investigation of the condition of the subsurface soils and groundwater
thereof. No information or knowledge obtained by SVG in any investigation
pursuant to this Section 5.1 will affect or be deemed to modify any
representation or warranty contained herein or the conditions to the obligations
of the parties to consummate the Acquisition.



                                      -31-
<PAGE>   37

        5.2     Public Disclosure. Until the earlier to occur of the Closing or
the termination of this Agreement pursuant to Section 8.1, neither SVG nor
Watkins-Johnson will issue any written statement or communication to any third
party (other than their respective agents) regarding the Acquisition without
first consulting with the other party and giving the other party an opportunity
to review the proposed written statement or communication, except for any such
written statements or communications as may be required by applicable law or any
listing agreement with a national securities exchange.

        5.3     Legal Requirements. Each of SVG, and Watkins-Johnson will take
all reasonable actions necessary or desirable to comply promptly with all legal
requirements which may be imposed on them with respect to the consummation of
the transactions contemplated by this Agreement (including furnishing all
information required in connection with approvals by or filings with any
Governmental Entity, and prompt resolution of any litigation prompted hereby)
and will promptly cooperate with and furnish information to any party hereto
necessary in connection with any such filings with or investigations by any
Governmental Entity, and any other such requirements imposed upon any of them or
their respective subsidiaries in connection with the consummation of the
transactions contemplated by this Agreement.

        5.4     Third Party Consents. As soon as practicable following the date
hereof, SVG and Watkins-Johnson will each use its commercially reasonable
efforts to obtain all consents, waivers and approvals under any of its or an SEG
Entity's Contracts or Leases required to be obtained in connection with the
consummation of the transactions contemplated hereby, as set forth on SCHEDULE
2.4. The parties agree that any monetary or other consideration paid to any
third party in order to procure any such consents, waivers or approvals shall be
split equally between the parties; provided that neither SVG nor Watkins-Johnson
shall be required to pay in excess of $5,000 under this SECTION 5.4. SVG shall
use commercially reasonable efforts to have Watkins-Johnson released fully from
all of its obligations under the Japanese Loans.

        5.5     Notification of Certain Matters. SVG and will give prompt notice
to Watkins-Johnson, and Watkins-Johnson will give prompt notice to SVG, of the
occurrence, or failure to occur, of any event, which occurrence or failure to
occur would be reasonably likely to cause (a) any representation or warranty
contained in this Agreement and made by it to be untrue or inaccurate in any
material respect at any time from the date of this Agreement to the Closing Date
such that the conditions set forth in Section 6.1(a) or 6.2(a), as the case may
be, would not be satisfied as a result thereof or (b) any material failure of
SVG or Watkins-Johnson, as the case may be, or of any officer, director,
employee or agent thereof, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement.
Notwithstanding the above, the delivery of any notice pursuant to this section
will not limit or otherwise affect the remedies available hereunder to the party
receiving such notice.

        5.6     Best Efforts and Further Assurances. Subject to the respective
rights and obligations of SVG and Watkins-Johnson under this Agreement, each of
the parties to this Agreement will use its reasonable best efforts to effectuate
the Acquisition and the other transactions contemplated hereby and



                                      -32-
<PAGE>   38

to fulfill and cause to be fulfilled the conditions to Closing under this
Agreement; provided that neither SVG, Watkins-Johnson, any SEG Entity nor any
subsidiary or Affiliate thereof will be required to agree to any divestiture by
itself or any of its Affiliates of shares of capital stock or of any business,
assets or property, or the imposition of any material limitation on the ability
of any of them to conduct their businesses or to own or exercise control of such
assets, properties and stock. Subject to the foregoing, each party hereto, at
the reasonable request of another party hereto, will execute and deliver such
other instruments and do and perform such other acts and things as may be
necessary or desirable for effecting completely the consummation of the
transactions contemplated hereby.

        5.7     Regulatory Filings. As soon as may be reasonably practicable,
Watkins-Johnson and SVG each shall file with the United States Federal Trade
Commission (the "FTC") and the Antitrust Division of the United States
Department of Justice (the "DOJ") Notification and Report Forms relating to the
transactions contemplated herein as required by the HSR Act, as well as
comparable pre-acquisition notification forms required by the acquisition
notification or control laws and regulations of any applicable jurisdiction, as
agreed to by the parties. Watkins-Johnson and SVG each shall promptly (a) supply
the other with any information which may be required in order to effectuate such
filings and (b) supply any additional information which reasonably may be
required by the FTC, the DOJ or the competition or acquisition control
authorities of any other jurisdiction and which the parties may reasonably deem
appropriate.

        5.8     Covenant Not to Compete. For a period of three (3) years from
the Closing Date, Watkins-Johnson will not directly or indirectly (i) manage or
control any entity engaged in a business competitive with the Business or
conduct any business competitive with the Business in any territory worldwide,
(ii) solicit any of the employees of the Business for purposes of obtaining
their services or hire any such employee unless such employee is not at the
time, and has not been for a period of three months prior to the date of hire,
an employee of the Business, or (iii) solicit any customers of SVG for any
direct or indirect purpose related to the Business. Notwithstanding the
restrictions set forth in clause (ii) above, Watkins-Johnson may place
advertisements in general circulation publications for employment opportunities,
which shall not be deemed a direct or indirect solicitation of SVG employees. If
the final judgment of a court of competent jurisdiction declares that any term
or provision of this Section 5.8 is invalid or unenforceable, the parties hereto
agree that the court making the determination of invalidity or unenforceability
shall have the power to reduce the scope, duration or area of the term or
provision, to delete specific words or phrases, or to replace any invalid or
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision, and this Section 5.8 shall be enforceable as so
modified.

        5.9     Employee Matters. Prior to the Closing, Watkins-Johnson shall
use its reasonable commercial efforts to assist SVG in hiring the services of
those employees and consultants of the Business identified by SVG; provided,
however, that Watkins-Johnson shall not be required to offer employees
additional monetary or other inducements to achieve that end beyond those in
place on the date of this Agreement. All severance policies and employment
arrangements with respect to the employees, including their annual salaries or
hourly rates, start dates, and title or position, and the



                                      -33-
<PAGE>   39

maximum dollar cost of each such employee severance and the maximum period of
company paid medical benefits (to the extent not prohibited by applicable law),
who work solely or primarily for the Business on the date of this Agreement (the
"SEG EMPLOYEES") will be identified on a schedule to be delivered by
Watkins-Johnson to SVG prior to the Closing (which schedule may be delivered in
portions by country or SEG Entity). SVG shall determine the SEG Employees who
will be retained within six months after the date of the final portion of the
schedule is received by SVG (if delivered in sections) or the complete schedule
referred to in the preceding sentence. Watkins-Johnson shall pay all severance
costs (to the extent such costs do not exceed Watkins-Johnson's standard company
policies which policies may vary from country to country) for up to but not more
than the first 15% of the SEG Employees employed on the date of this Agreement
who are not retained beyond that six-month period, provided that the total
amount of such costs that Watkins-Johnson shall be obligated to pay shall not
exceed $2,500,000. In addition, Watkins-Johnson shall be responsible for all
severance costs payable under all special severance benefit arrangements between
Watkins-Johnson or an SEG Entity and an SEG Employee entered into before the
Closing (whether before or after the date of this Agreement) to the extent that
such benefits exceed the amounts payable to that SEG Employee under the standard
company policies referenced previously. The amounts payable to such SEG
Employees that do not exceed the amounts payable under those standard company
policies shall be governed by the 15% and $2,500,000 rules stated above. Nothing
in this Section 5.9 shall require Watkins-Johnson to pay any SEG Employee any
severance benefits (or to reimburse SVG or any other entity for any severance
benefits) for which, before the Closing, neither Watkins-Johnson nor any SEG
Entity would have been obligated to pay to that SEG Employee had that employee's
employment been terminated prior to the Closing.

        5.10    Tax Matters. Watkins-Johnson and SVG hereby covenant and agree
with respect to certain tax matters as follows:

                (a)     Asset Purchase.

                        (i)     The parties shall treat the purchase of the SEG
LLC Interests as a purchase of the assets held by the SEG LLC for all federal
and state income tax purposes.

                        (ii)    Within ninety (90) days after Closing, SVG shall
provide to Watkins- Johnson a schedule which sets forth the proposed allocation
(the "ALLOCATION SCHEDULE") of the Adjusted Consideration (including any
Included Liabilities owed by SEG LLC) to and among the Included Assets
(including the assets held by SEG LLC and deemed purchased in accordance with
Section 5.10(a)(i)) and to and among the International Subsidiary Capital Stock.
Such allocations shall be made in accordance with Section 1060 of the Code and
any applicable Treasury Regulations. Watkins-Johnson shall be deemed to have
accepted the Allocation Schedule, and it shall be deemed final, unless Watkins-
Johnson provides written notice of disagreement to SVG within thirty (30) days
of receipt of the Allocation Schedule (the "DISAGREEMENT NOTICE"). If
Watkins-Johnson provides a Disagreement Notice, the parties shall negotiate in
good faith to resolve the differences. If the disagreements are not resolved
within thirty (30) days of SVG's receipt of the Disagreement Notice, SVG shall
engage a national independent accounting firm (the "ACCOUNTANT"), acceptable to
Watkins-Johnson, to resolve



                                      -34-
<PAGE>   40

the differences. The Accountant will be requested to resolve the dispute and
determine the correct allocation in accord with Section 1060 of the Code, and
issue its report within 30 days of engagement, in writing to SVG and
Watkins-Johnson (the "ACCOUNTANT REPORT"). One-half of the fees of the
Accountant shall be borne by Watkins-Johnson, and one-half of such fees shall be
borne by SVG. No party will take a position on any Tax Return, before any
governmental Tax agency or in a judicial proceeding that is inconsistent with
the Allocation Notice, if final, or the Accountant Report, except as required by
law.

                (b)     Returns; Indemnification; Liability for Taxes.

                        (i)     Watkins-Johnson shall prepare and file (or cause
to be prepared and filed) on a timely basis all Tax Returns with respect to each
of the SEG Entities for all taxable periods ending on or before the Closing Date
("SEG TAX RETURNS") and shall pay to the extent modified by Section 5.10(c) of
this Agreement and, subject to Article V, shall indemnify and hold SVG harmless
against and from (i) all Taxes of Watkins-Johnson, SEG Sub or any other domestic
or foreign Affiliate of such entities including all such Taxes attributable to
the Included Assets or the operation of the Business for all taxable periods (or
any portion thereof) which end on or before the Closing Date (except to the
extent such Taxes have been shown as an Included Liability for purposes of
determining the Closing Net Asset Value); (ii) all Taxes of the SEG Entities for
all taxable years or periods which end on or before the Closing Date (except to
the extent such Taxes have been shown as an Included Liability for purposes of
determining the Closing Net Asset Value); (iii) all Taxes for all taxable years
or periods of all members of any affiliated, consolidated, combined or unitary
group of which the SEG Entities are or have been a member prior to the Closing
Date; and (iv) with respect to any taxable period of the SEG Entities (other
than the SEG Sub) commencing before the Closing Date and ending after the
Closing Date (a "STRADDLE PERIOD") all Taxes of the SEG Entities attributable to
the portion of the Straddle Period prior to and including the Closing Date (the
"PRE-CLOSING PERIOD") (except to the extent such Taxes have been shown as an
Included Liability for purposes of determining the Closing Net Asset Value). For
purposes of this Agreement, the portion of any Tax that is attributable to the
Pre-Closing Period shall be (i) in the case of a Tax (including any property or
ad valorem Tax) that is not based on net income, gross income, premiums or gross
receipts, the total amount of such Tax for the period in question multiplied by
a fraction, the numerator of which is the number of days in the Pre-Closing
Period, and the denominator of which is the total number of days in such
Straddle Period, and (ii) in the case of a Tax that is based on any of net
income, gross income, premiums or gross receipts, the Tax that would be due with
respect to the Pre-Closing Period if such Pre-Closing Period were a separate
taxable period, except that exemptions, allowances, deductions or credits that
are calculated on an annual basis (such as the deduction for depreciation or
capital allowances) shall be apportioned on a per diem basis. For purposes
hereof, all Taxes which are the subject of this Section 5.10 arising from the
Acquisition, except as set forth in Section 5.10(f), shall be deemed to be Taxes
attributable to the Pre-Closing Period and shall be the responsibility of
Watkins-Johnson.

                        (ii)    SVG shall prepare and file (or cause to be
prepared and filed) on a timely basis all Tax Returns of the SEG Entities
relating to periods ending after the Closing Date and shall pay, to the extent
modified by Section 5.10(c) of this Agreement, and, subject to Article VII,
shall indemnify



                                      -35-
<PAGE>   41

and hold Watkins-Johnson harmless against and from (i) all Taxes of the SEG
Entities (other than the SEG Sub) for any taxable year or period commencing
after the Closing Date; and (ii) all Taxes of the SEG Entities (other than the
SEG Sub) for any Straddle Period other than Taxes attributable to the
Pre-Closing Period.

                (c)     Cooperation; Refunds and Credits.

                        (i)     All refunds or credits of Taxes for or
attributable to taxable years or periods of the SEG Entities ending on or before
the Closing Date (or the Pre-Closing Period, in the case of a Straddle Period)
shall be for the account of Watkins-Johnson, except to the extent such refund or
credit was reflected as an Included Asset in the determination of the Closing
Net Asset Value; all other refunds or credits of Taxes, for or attributable to
the SEG Entities shall be for the account of SVG. Following the Closing, SVG
shall cause the SEG Entities to forward to Watkins-Johnson any such refunds or
credits due Watkins-Johnson pursuant to this section within thirty (30) days
after receipt or realization thereof by SVG, and Watkins-Johnson shall forward
(or cause to be forwarded) to SVG any refunds or credits due to SVG pursuant to
this section after receipt or actual realization thereof by Watkins-Johnson, in
each case in accordance with the provisions of subsection (iv) below.

                        (ii)    If an audit examination of any Tax Return of
Watkins-Johnson or its subsidiaries for any taxable period ending on or before
the Closing Date shall result (by settlement or otherwise) in any adjustment the
effect of which is to increase deductions, losses or tax credits or decrease
income, gains, premiums, revenues or recapture of tax credits ("CHANGES")
reflected on a Tax Return of SVG or the SEG Entities for any taxable period
ending after the Closing Date, Watkins-Johnson will notify SVG and provide it
with all necessary information so that it can reflect on the appropriate Tax
Return any appropriate Changes. If as a result of such Changes, SVG or its
subsidiaries enjoy a net Tax benefit from an increase in deductions, losses or
tax credits and/or a decrease in income, gains, premiums, revenues or recapture
of tax credits ("SVG BENEFITS") for taxable periods ending after the Closing
Date, SVG shall pay to Watkins-Johnson the amount of such SVG Benefit, within
thirty (30) days of when such SVG Benefits are actually realized by SVG in
accordance with subsection (iv) below.

                        (iii)   If an audit examination of any Tax Return of SVG
or its subsidiaries for taxable periods ending after the Closing Date shall
result (by settlement or otherwise) in any Change reflected on a Tax Return of
Watkins-Johnson or its subsidiaries for any taxable periods ending on or before
the Closing Date, SVG will notify Watkins-Johnson and provide it with all
necessary information so that Watkins-Johnson can reflect any appropriate
Changes on its Tax Return. If as a result of such Changes, Watkins-Johnson or
its subsidiaries enjoy a net Tax benefit from an increase in deductions, losses
or tax credits and/or a decrease in the income, gains, premiums, revenues or
recapture of tax credits ("WATKINS-JOHNSON BENEFITS") for taxable periods ending
on or before the Closing Date, Watkins-Johnson shall pay to SVG the amount of
such Watkins-Johnson Benefits within thirty (30) days of when such
Watkins-Johnson Benefits are actually realized by Watkins-Johnson, in accordance
with subsection (iv) below.



                                      -36-
<PAGE>   42

                        (iv)    Any payments of refunds or credits for Taxes, or
any payment of SVG Benefits or Watkins-Johnson Benefits, that are required to be
paid under this Agreement shall be made within ten (10) Business Days of the
receipt of any refund or thirty (30) Business Days of the actual realization of
any tax benefit, as the case may be.

                (d)     Termination of Tax Sharing Agreements. Watkins-Johnson
hereby agrees that, except for this Agreement, there are no, and as of the
Closing there will be no, obligations of or to the SEG Entities pursuant to any
tax sharing agreement or any similar arrangement, and any further obligations
that might otherwise have existed thereunder shall be extinguished as of the
Closing.

                (e)     Conduct of Audits and Other Procedural Matters. Each
party shall, at its own expense, control any audit or examination by any taxing
authority, and have the right to initiate any claim for refund or amended
return, and contest, resolve and defend against any assessment, notice of
deficiency or other adjustment or proposed adjustment of Taxes ("PROCEEDINGS")
for any taxable period for which that party is charged with payment or
indemnification responsibility under this Agreement. Each party shall promptly
forward to the other all written notifications and other written communications,
including if available the original envelope showing any postmark, from any
taxing authority received by such party or its affiliates relating to any
liability for Taxes for any taxable period for which such other party or any of
its affiliates is charged with sole payment or indemnification responsibility
under this Agreement and each indemnifying party shall promptly notify, and
consult with, each indemnified party as to any action it proposes to take with
respect to any liability for Taxes for which it is required to indemnify another
party and shall not enter into any closing agreement or final settlement with
any taxing authority with respect to any such liability without the written
consent of the indemnified parties, which consent shall not be unreasonably
withheld. In the case of any Proceedings relating to any Straddle Period, SVG
shall control such Proceedings and shall consult in good faith with
Watkins-Johnson as to the conduct of such Proceedings. Watkins-Johnson shall
reimburse SVG for such portion of the costs, including legal costs, of
conducting such Proceedings as is represented by the portion of the Tax with
respect to such Straddle Period for which Watkins-Johnson is liable pursuant to
this Agreement. Each party shall, at the expense of the requesting party,
execute or cause to be executed any powers of attorney or other documents
reasonably requested by such requesting party to enable it to take any and all
actions such party reasonably requests with respect to any Proceedings which the
requesting party controls. The failure by a party to provide timely notice under
this subsection shall relieve the other party from its obligations under this
Section 5.10 with respect to the subject matter of any notification not timely
forwarded, but only to the extent the other party has suffered a loss or other
economic detriment because of such failure to provide notification in a timely
fashion.

                (f)     Transfer Taxes. Notwithstanding anything to the contrary
in this Agreement, including this Section 5.10, except as set forth in Section
1.6 all transfer, documentary, sales, use, stamp, registration and other such
taxes and fees (including any penalties and interest) incurred in connection
with the transactions contemplated by this Agreement (other than (i) any such
taxes incurred in connection with the transfer to Watkins-Johnson (or the
acquisition by SVG) of the SEG International Subsidiary Capital Stock, which
taxes shall be borne by Watkins-Johnson, or (ii) any such transfer taxes

SEG Sub, which Taxes

shall be borne by Watkins-Johnson) shall be paid by SVG when due. The parties
hereto agree to treat the transfer of assets by the SEG Sub to SEG LLC and the
sale of the SEG LLC Interests as exempt from any transfer taxes and
Watkins-Johnson shall not take any position inconsistent with such
understanding. SVG and Watkins-Johnson shall cooperate in the filing of all
necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other taxes and fees.

                (g)     Section 338 Election. SVG shall give Watkins-Johnson
thirty (30) days prior written notice of any intention to file an election under
Section 338(g) of the Code with respect to any of the SEG International
Entities.

        5.11    Change of Names; License of use of "wj". As promptly as
practicable after the Closing, SVG shall (a) cause each of the SEG International
Entities to amend its charter and take any and all other actions necessary to
remove the "Watkins-Johnson" name from each of the SEG International Entities'
corporate names; (b) remove, or cause to be removed, all references to "wj" in
the URL's for the SEG Entities' Internet sites as listed on SCHEDULE 5.11
hereto; and (c) cease (and cause each of the SEG Entities to cease) using that
name, the "WJ" initials and any similar name or initials in its operations or
otherwise. Effective as of the Closing, Watkins-Johnson hereby grants SVG and
its Affiliates a royalty free worldwide perpetual license to use the initials
"wj" in the names of the products and related services and manuals currently
being commercialized in the Business. SVG acknowledges that the sole ownership
of the initials "wj" remains with Watkins-Johnson. SVG agrees that it will do
nothing inconsistent with such ownership. SVG will comply with all reasonable
requests of Watkins- Johnson in connection with SVG's use of the initials "wj."
SVG's use of the initials "wj" shall reasonably conform with the standards
practiced by Watkins-Johnson and the SEG Entities in the past.

        5.12    Collection of Receivables.

                (a)     In General. After the Closing, SVG and the SEG Entities
shall seek to collect all accounts receivable outstanding as of the Closing Date
for products and services shipped or rendered by any SEG Entity or the Business
before the Closing. In doing so, SVG and the SEG Entities shall use reasonable
commercial efforts to collect such receivables. SVG and the SEG Entities shall
incur the costs and expenses of such collection procedures, except that
Watkins-Johnson shall pay all out-of-pocket costs and expenses incurred in
connection with any extraordinary collection efforts, such as any litigation
with customers, in excess of the normal collection procedures SVG uses to
collect its own receivables. Within fifteen (15) days after the Closing,
Watkins-Johnson shall deliver to SVG an aging of all accounts receivable of the
Business, which aging shall be reconciled to the general ledger accounts of
Watkins-Johnson and shall be true and accurate. SVG shall have fifteen (15) days
from the date of receipt of the accounts receivable aging to review such aging,
and if it disagrees with anything in the accounts receivable aging, SVG and
Watkins-Johnson shall in good faith attempt to resolve any disputes or
discrepancies in the accounts receivable aging. The final accounts receivable
aging as of the Closing Date agreed to by the parties (or as determined by the
independent accounting firm, as provided in the following paragraph, as the case
may be) is herein referred to as the "CLOSING DATE RECEIVABLES." Watkins-Johnson
and SVG shall also mutually agree on certain Closing Date Receivables (the
"SPECIAL



                                      -38-
<PAGE>   44

RECEIVABLES") (i) that have deferred payment plans or long-term payment plans
that become due after the Closing, (ii) that are at least 45 days overdue as of
the date of the aging, or (iii) that are subject to a dispute with a customer,
which receivables shall be excluded from the calculations described in Section
5.12(c) below. Notwithstanding the preceding sentence, if any Special
Receivables (x) that have deferred or long-term payment plans are paid on a
timely basis, (y) that were overdue at least 45 days as of the date of the aging
are paid within the time periods set forth in Section 5.12(c), or (z) that had
been subject to a dispute for which the dispute has been subsequently resolved,
will be removed from the Special Receivables for purposes of the calculations
set forth in Section 5.12(c).

        If the parties do not agree on the Closing Date Receivables or the
Special Receivables within such fifteen (15) day period, the parties shall
engage PricewaterhouseCoopers LLP, or if PricewaterhouseCoopers LLP is unable to
perform such services, a mutually agreed upon independent accounting firm of
national standing and reputation, to determine the Closing Date Receivables and
the Special Receivables. Such determination by the independent accounting firm
shall be final and binding on the parties. The cost of the services of the
independent accounting firm shall be borne by Watkins-Johnson.

                (b)     Procedures. The parties shall cooperate in good faith to
achieve the purposes of this Section 5.12. Each month, SVG shall furnish a
report to Watkins-Johnson that shows the collected Closing Date Receivables as
of the end of SVG's accounting month, itemized by invoice for each foreign
entity and for domestic operations. The report shall be submitted by the
twentieth (20th) day after the end of SVG's accounting month. Watkins-Johnson
shall submit a report to SVG within twenty (20) days after receiving each of
SVG's report that shows the collections on Closing Date Receivables received by
Watkins-Johnson that SVG will be able to remove from the list of outstanding
Closing Date Receivables. SVG shall remit or cause to be remitted to
Watkins-Johnson all Closing Date Receivables collected by SVG or any SEG Entity
that are payable to Watkins-Johnson by the twentieth (20th) day after the end of
SVG's accounting month during which the payments were received. If
Watkins-Johnson receives payments on Closing Date Receivables (or any other
receivables) that belong to SVG, Watkins-Johnson shall likewise remit those
payments to SVG by the twentieth (20th) day after the end of the Watkins-Johnson
accounting month during which the payments were received. Upon reasonable
notice, Watkins-Johnson and its representatives shall have access to all
information and documents in the custody or control of SVG or any SEG Entity
that bear on the matters addressed in this Section 5.12. Likewise, upon
reasonable notice, SVG and its representatives shall have access to all
information and documents in the custody or control of Watkins-Johnson or any of
its subsidiaries that bear on the matters addressed in this Section 5.12.

                (c)     Application to Receivables. Amounts collected on Closing
Date Receivables shall be applied to such receivables of that customer or group
on an identified invoice basis; provided, however, that if SVG has not collected
at least the percentage of Closing Date Receivables (excluding for purposes of
the numerator and denominator the Special Receivables and any Closing Date
Receivables subject to a dispute through no fault of SVG or any SEG Entity after
the Closing) set forth in the following table within the time periods set forth
opposite such percentages, SVG shall purchase from Watkins-Johnson all remaining
outstanding Closing Date Receivables (excluding the Special



                                      -39-

receivable was denominated.

                (e)     Collection Issues. For receivables that are or become
delinquent, Watkins- Johnson will be permitted to contact the customer directly
for the purpose of pursuing collection. SVG will cooperate with Watkins-Johnson
in that effort, if Watkins-Johnson so requests.

or SVG Indemnified Party (an "INDEMNIFIED PARTY") has a Claim against any party
obligated to provide indemnification pursuant to Section 7.1 or 7.2 hereof (an
"INDEMNIFYING PARTY") which does not involve a Claim being asserted against or
sought to be collected by a third party, the Indemnified Party shall with
reasonable promptness notify the Indemnifying Party of such Claim, with a copy
to the Escrow Agent, if applicable, specifying the nature of such Claim and the
amount or the estimated amount thereof to the extent then feasible (the "CLAIM
NOTICE"). If the Indemnifying Party does not notify in writing the Indemnified
Party within thirty (30) days after the date of delivery of the Claim Notice
that the Indemnifying Party disputes such Claim, with a statement in reasonable
detail (to enable the Indemnified Party to understand the nature of the dispute)
of the basis of such position (a "NOTICE OF OBJECTION"), a copy of which is
delivered to the Escrow Agent, if applicable, the amount of such Claim shall be
conclusively deemed a liability of the Indemnifying Party hereunder. In case a
Notice of Objection is delivered to the Indemnified Party in accordance with
this Section 7.4(a), the Indemnified Party shall respond in a written statement
to the Notice of Objection within thirty (30) days and, for sixty (60) days
thereafter, the parties shall attempt in good faith to resolve such dispute
(and, if the parties should so agree, a memorandum setting forth such agreement
shall be prepared and signed by both parties). If the parties do not resolve the
dispute within such sixty (60) day period, either party may demand arbitration
of the matter unless



                                      -46-
<PAGE>   52

the amount of the Damages is at issue in pending litigation with a third party,
in which event arbitration shall not be commenced until such amount is
ascertained or both parties agree to arbitration. Any arbitration under this
Section 7.4 shall be conducted in accordance with Section 9.7.

                (b)     (i)     In the event that any Claim for which the
Indemnifying Party would be liable to an Indemnified Party hereunder is asserted
against an Indemnified Party by a third party (a "THIRD PARTY CLAIM"), the
Indemnified Party shall promptly deliver a Claim Notice to the Indemnifying
Party. The Indemnifying Party shall have thirty (30) days from date of delivery
of the Claim Notice to notify the Indemnified Party (A) whether the Indemnifying
Party disputes liability to the Indemnified Party hereunder with respect to the
Third Party Claim, and, if so, the basis for such a dispute, and (B) whether or
not the Indemnifying Party desires, at the sole cost and expense of the
Indemnifying Party, to defend against the Third Party Claim, provided that the
Indemnified Party, at its sole cost and expense, is hereby authorized (but not
obligated) to file any motion, answer or other pleading and to take any other
reasonable action which the Indemnified Party shall deem necessary or
appropriate to protect the Indemnified Party's interests.

                        (ii)    If the Indemnifying Party elects to defend the
Indemnified Party against such Third Party Claim by appropriate proceedings,
then, unless the Indemnified Party otherwise agrees in writing, the Indemnifying
Party may not settle any Third Party Claim (in whole or in part) if such
settlement does not include a complete and unconditional release of the
Indemnified Party. If the Indemnified Party desires to participate in, but not
control, any such defense or settlement the Indemnified Party may do so at its
sole cost and expense. If the Indemnifying Party elects not to defend the
Indemnified Party against a Third Party Claim, whether by failure of such party
to give the Indemnified Party timely notice as provided herein or otherwise,
then the Indemnified Party, without waiving any rights against such party, may
settle or defend against such Third Party Claim in the Indemnified Party's
reasonable discretion and the Indemnified Party shall be entitled to recover
from the Indemnifying Party or the Escrow Amount, as provided in Section 7.5,
the amount of any settlement or judgment and, on an ongoing basis, all
indemnifiable costs and expenses of the Indemnified Party with respect thereto.

                        (iii)   If at any time, in the reasonable opinion of the
Indemnified Party, notice of which shall be given in writing to the Indemnifying
Party, any Third Party Claim seeks material prospective relief which could have
an adverse effect on any Indemnified Party or the SEG Entities or the Business,
the Indemnified Party shall have the right to control or assume (as the case may
be) the defense of any such Third Party Claim and the amount of any judgment or
settlement and the reasonable costs and expenses of defense shall be included as
part of the indemnification obligations of the Indemnifying Party hereunder. If
the Indemnified Party elects to exercise such right, the Indemnifying Party
shall have the right to participate in, but not control, the defense of such
Third Party Claim at the sole cost and expense of the Indemnifying Party.

                (c)     The Indemnified Party shall cooperate fully with the
Indemnifying Party to defend Third Party Claims as reasonably requested by the
Indemnifying Party by, for example, making relevant



                                      -47-

employees reasonably available and providing reasonable access to documents and
information during normal business hours and with prior notification.

                (d)     Subject to Section 7.3, nothing herein shall be deemed
to prevent the Indemnified Party from making a Claim, and an Indemnified Party
may make a Claim hereunder, for potential or contingent Damages provided,
however, that within thirty (30) days of notifying the Indemnifying Party of
such potential or contingent claim, the Indemnified Party delivers to the
Indemnifying Party a Claim Notice that sets forth the specific basis for any
such Claim.

                (e)     Subject to the provisions of Section 7.3, the
Indemnified Party's failure to give reasonably prompt notice as required by this
Section 7.4 of any actual, threatened or possible claim or demand which may give
rise to a right of indemnification hereunder shall not relieve the Indemnifying
Party of any liability which the Indemnifying Party may have to the Indemnified
Party unless the failure to give such notice materially and adversely prejudiced
the Indemnifying Party.

                (f)     In the event of any inconsistency between the procedures
set forth in this Section 7.4 and the procedures set forth in Section 5.10
(relating to Taxes), Section 5.10 shall control.

        7.5     Escrow Fund; Appointment of Escrow Agent; Exclusive Remedy.
Watkins-Johnson and SVG hereby agree to the creation of an escrow fund to
satisfy Watkins-Johnson's indemnification obligations to the SVG Indemnified
Parties pursuant to the terms of this Article 7. Watkins-Johnson will be deemed
to have received and deposited with the Escrow Agent the Escrow Amount and all
interest and earnings accruing on the Escrow Amount shall accrue to (and be
taxable currently to) Watkins-Johnson. The Escrow Amount, and all interest and
earnings thereon (collectively, the "ESCROW FUND") and all claims or demands for
payment out of the Escrow Fund shall be governed by the terms of the Escrow
Agreement in substantially the form attached hereto as EXHIBIT A.
Watkins-Johnson and SVG hereby appoint an Escrow Agent to administer the Escrow
Fund. Watkins-Johnson and SVG shall each bear one-half of the fees and expenses
of the Escrow Agent incurred in connection with the establishment and
maintenance of the Escrow Fund. The parties agree and acknowledge that the
Escrow Fund (but no more than $3,450,000) shall be the SVG Indemnified Parties'
sole and exclusive remedy for Damages for which Watkins-Johnson shall be liable
under Section 7.1, except as set forth in Section 7.3(a).

        7.6     Survival of Representations; Warranties and Covenants. The
representations of Watkins-Johnson will survive the Closing and will remain in
effect until, and will expire in accordance with Section 7.3. The
representations of SVG will survive the Closing and will remain in effect until,
and will expire in accordance with Section 7.3.

                        TERMINATION, AMENDMENT AND WAIVER

        8.1     Termination. This Agreement may be terminated at any time prior
to the Closing Date:

                (a)     by mutual written consent duly authorized by the Boards
of Directors of SVG and Watkins-Johnson;

                (b)     by either Watkins-Johnson or SVG if the Acquisition
shall not have been consummated by June 30, 1999 for any reason; provided,
however, that the right to terminate this Agreement under this Section 8.1(b)
shall not be available to any party whose action or failure to act has been a
principal cause of or resulted in the failure of the Acquisition to occur on or
before such date and such action or failure to act constitutes a breach of this
Agreement;

                (c)     by either Watkins-Johnson or SVG if a Governmental
Entity shall have issued an order, decree or ruling or taken any other action,
in any case having the effect of permanently restraining, enjoining or otherwise
prohibiting the Acquisition, which order, decree, ruling or other action is
final and nonappealable;

                (d)     by Watkins-Johnson, upon a material breach of any
representation, warranty, covenant or agreement on the part of SVG set forth in
this Agreement, or if any representation or warranty of SVG shall have become
materially untrue, in either case such that the conditions set forth in Section
6.1(a) or Section 6.1(b) would not be satisfied as of the time of such breach or
as of the time such representation or warranty shall have become untrue,
provided that if such inaccuracy in SVG's representations and warranties or
breach by SVG is curable by SVG through the exercise of its commercially
reasonable efforts, then Watkins-Johnson may not terminate this Agreement under
this Section 8.1(d) for thirty (30) days after notice from Watkins-Johnson of
such breach has been delivered to SVG, provided SVG continues to exercise such
commercially reasonable efforts to cure such breach; or

                (e)     by SVG, upon a material breach of any representation,
warranty, covenant or agreement on the part of Watkins-Johnson set forth in this
Agreement, or if any representation or warranty of Watkins-Johnson shall have
become materially untrue, in either case such that the conditions set forth in
Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of such
breach or as of the time such representation or warranty shall have become
untrue, provided, that if such inaccuracy in Watkins-Johnson's representations
and warranties or breach by Watkins-Johnson is curable by Watkins-Johnson
through the exercise of its commercially reasonable efforts, then SVG may not
terminate this Agreement under this Section 8.1(e) for thirty (30) days after
notice from SVG of such breach has been delivered to Watkins-Johnson, provided
Watkins-Johnson continues to exercise such commercially reasonable efforts to
cure such breach.

        8.2     Notice of Termination; Effect of Termination. Any termination of
this Agreement under Section 8.1 above will be effective immediately upon the
delivery (subject to the cure periods set forth



                                      -49-
<PAGE>   55

in Section 8.1(d) and (e)), of written notice of the terminating party to the
other parties hereto. In the event of the termination of this Agreement as
provided in Section 8.1, this Agreement shall be of no further force or effect,
except (i) as set forth in this Section 8.2, Section 8.3 and Article 9, each of
which shall survive the termination of this Agreement, and (ii) nothing herein
shall relieve any party from liability for any breach of this Agreement. In
addition, subject to the next sentence, Watkins-Johnson shall return the Earnest
Money Payment to SVG in immediately available funds within three (3) Business
Days of any termination of this Agreement pursuant to Section 8.1 and, before or
at the time of such termination SVG has notified Watkins-Johnson in writing that
(i) SVG, as a result of its customer due diligence, determines, in its sole
reasonable discretion, that the value of the Business is materially and
adversely different from that previously represented to SVG by Watkins-Johnson,
(ii) SVG determines, in its sole reasonable discretion, that the financial
condition or prospects of the Business are materially and adversely different
from that previously represented to SVG by Watkins-Johnson, including any
material reduction in the value or utility of the real property assets of the
SEG Entities, (iii) there is any governmental action pending or threatened with
respect to the Acquisition or the other transactions contemplated hereby that
would seek to block or alter the terms of such transactions as set forth herein,
including actions based on federal antitrust laws, (iv) there has been a
material adverse change in the Business or the desirability of the Business to
SVG that causes the value of the Business to be materially and adversely
different than previously represented to SVG by Watkins-Johnson, in SVG's
reasonable discretion, including a material difference in the appraised value of
the Included Assets and the Included Liabilities identified, (v) SVG determines,
in its reasonable discretion, that other transactions or corporate governance
matters in which Watkins-Johnson is or may be involved will materially affect
the timing or the ability to consummate the Acquisition and other transactions
contemplated hereby, or (vi) the parties are unable to agree on the tax
treatment of the Acquisition or the other transactions contemplated hereby. In
order to invoke its rights under the previous sentence, SVG must base its
decision to terminate this Agreement either on an event or development that took
place after the date of this Agreement or information or analysis of which SVG
first became aware after the date of this Agreement. If this Agreement is
terminated in accordance with Section 8.1 and the preceding sentence does not
apply, Watkins-Johnson shall retain the Earnest Money Payment. No termination of
this Agreement shall affect the obligations of the parties contained in the
Confidentiality Agreement, all of which obligations shall survive termination of
this Agreement in accordance with their terms.

        8.3     Fees and Expenses. All fees and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such expenses whether or not the Acquisition is consummated.

        8.4     Amendment. Subject to applicable law, this Agreement may only be
amended hereto by execution of an instrument in writing signed on behalf of each
of the parties hereto.

        8.5     Extension; Waiver. At any time prior to the Closing Date any
party hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such



                                      -50-
<PAGE>   56

party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party, provided that, if the Acquisition
closes, any unsatisfied conditions set forth in Section 6.1 or 6.2 of this
Agreement shall be deemed waived even without such an instrument. Delay in
exercising any right under this Agreement shall not constitute a waiver of such
right.

Exhibits, such reference shall be to an Exhibit to this Agreement unless
otherwise indicated. The words "include," "includes" and "including" when used
herein shall be deemed in each case to be followed by the words "without
limitation." The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Reference to the subsidiaries of an entity
shall be deemed to include all direct and indirect subsidiaries of such entity.

        9.3     Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

        9.4     Entire Agreement; Third Party Beneficiaries. This Agreement and
the documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Watkins-Johnson Disclosure
Schedules (a) constitute the entire agreement among the parties with respect to

provision

<PAGE>   58

to other persons or circumstances will be interpreted so as reasonably to effect
the intent of the parties hereto. The parties further agree to replace such void

other purposes of such void or unenforceable provision.

        9.6     Other Remedies. Except as otherwise provided herein including
Sections 7.3 and 7.5, any and all remedies herein expressly conferred upon a
party will be deemed cumulative with and not exclusive of any other remedy

and construed in accordance with the laws of the State of California, regardless
of the laws that might otherwise govern under applicable principles of conflicts
of law thereof; provided that issues involving the corporate governance of any
of the parties hereto shall be governed by their respective jurisdictions of
incorporation. Except as otherwise provided in this Agreement, any claim or
dispute arising out of or related to this Agreement, or the interpretation,
making, performance, breach or termination thereof, shall be finally settled by
binding arbitration in Santa Clara County, California under the rules of the
American Arbitration Association then in effect by a single arbitrator mutually
agreeable to Watkins-Johnson and SVG. In the event that within thirty (30) days
after the submission of any dispute to arbitration, Watkins-Johnson and SVG do
not mutually agree on a single arbitrator, Watkins-Johnson, on the one hand, and
SVG, on the other hand, shall each select one arbitrator and the AAA shall
select a third arbitrator. The arbitrator(s) shall have the authority to grant
any equitable and legal remedies that would be available in any judicial
proceeding instituted to resolve a dispute. Judgment on the award rendered by
the arbitrators may be entered in any court having jurisdiction thereof. The
arbitrator(s) may award to the prevailing party, if any, as determined by the
arbitrator(s), all of its costs and fees, including AAA administrative fees,
arbitrator fees, attorney's fees, expert fees, witness fees, travel expenses and
out-of-pocket expenses (including such expenses as copying, telephone,
facsimile, postage and courier fees). The parties to the arbitration may apply
to any court of competent jurisdiction for a temporary restraining order,
preliminary injunction or other interim or conservatory relief, as necessary,
without breach of this arbitration provision and without any abridgement of the
powers of the arbitrator(s). The parties agree that, any provision of applicable
law notwithstanding, they will not request and the arbitrator(s) shall have no
authority to award punitive or exemplary damages against any party.

        9.8     Rules of Construction. The parties hereto agree that they have
been represented by counsel during the negotiation and execution of this
Agreement and, therefore, waive the application of any law, regulation, holding
or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

        9.9     Assignment. No party may assign either this Agreement or any of
its rights, interests, or obligations hereunder without the prior written
approval of the other party, except that: (a) SVG may assign its rights to

subsidiaries and (b) SVG may assign its rights to acquire the Scotts Valley

        cash balances held by the SEG International Entities as of the Valuation
        Date; provided, however, that the value of the assets and liabilities,
        including the equipment related to the AP Next product, set forth under
        the caption "Fixed Valuation" on SCHEDULE 1.4 as of the Valuation Date
        shall be equal to the value of such



                                      -1-
<PAGE>   2

        assets and liabilities as of December 31, 1998; and, provided, further,
        that the inventory balances (net of reserves) determined in accordance
        with GAAP as of the Valuation Date shall be increased by $4,500,000. In
        addition, in order to determine the value of the Closing Net Assets,
        Watkins-Johnson, under the observation of SVG, performed a physical
        inspection and count of the inventory and equipment included in the
        Included Assets as of the close of business on June 25, 1999 in order to
        provide a "foundation" for determining the value of those assets as of
        the Valuation Date. Watkins-Johnson and SVG shall take whatever actions
        are reasonably appropriate to update those figures to the Valuation
        Date.

        2.      Section 8.1(b) of the Purchase Agreement is amended and restated
to read as follows:

        "by either Watkins-Johnson or SVG if the Acquisition shall not have been
        consummated by July 6, 1999 for any reason; provided, however, that the
        right to terminate this Agreement under this Section 8.1(b) shall not be
        available to any party whose action or failure to act has been a
        principal cause of or resulted in the failure of the Acquisition to
        occur on or before such date and such action or failure to act
        constitutes a breach of this Agreement;"

        3. Section 9.10 of the Purchase Agreement is amended to include the
following:

        " "VALUATION DATE" has the meaning set forth in Section 1.4."

        4.      If, and only if, there is a Closing under the Purchase
Agreement, SVG agrees that it shall be responsible for the ordinary and normal
expenses of the Business from 12:01 a.m., July 3, 1999 to (as well as after) the
Closing, and Watkins-Johnson agrees that all of the income, expenses and cash
flows of the Business shall be attributed to SVG during such period.
Watkins-Johnson further agrees that during such period it shall carry on the
Business diligently and in accordance with good commercial practice and in the
usual, regular and ordinary course, in accordance with Section 4.1 of the
Purchase Agreement, including without limitation maintaining, at its expense,
insurance coverage for all personal and real property and all employee-related
matters with respect to the Business.

        5.      Pursuant to Section 6.2(n) of the Purchase Agreement, all
accounts receivable in the SEG International Entities (the "INTERNATIONAL
RECEIVABLES") shall have been transferred to Watkins-Johnson or an Affiliate of
Watkins-Johnson that is not an SEG Entity prior to the Closing. The parties
agree that ownership of the International Receivables shall be transferred as
required as of the Closing; however, such transfers may not be perfected under
the laws applicable to all of the SEG International Entities. Among other tasks,
in order to perfect the transfers of ownership of the International Receivables,
letters must be sent to certain customers of the SEG International Entities.
Watkins-Johnson shall be and remain responsible for distributing the customer
letters, and in connection therewith, Watkins-Johnson is authorized, on behalf
of each of the SEG International Entities, to contact and notify customers of
each such entity of the change in ownership of such SEG International Entity and
the transfer and assignment



                                      -2-
<PAGE>   3

of the International Receivables to Watkins-Johnson. The form of such customer
notification letters shall be reviewed and approved by the parties hereto. In
the event that all the customer letters are not mailed prior to the Closing, SVG
agrees, and agrees to direct the SEG International Entities, to reasonably
cooperate with Watkins-Johnson by providing information that resides in the SEG
International Entities and personnel of the SEG International Entities to assist
in the distribution of such customer letters and shall assist in making relevant
filings with appropriate governmental authorities required of such SEG
International Entity so that Watkins-Johnson can complete the obligation. Any
personnel or other costs incurred by SVG pursuant hereto shall be paid by
Watkins-Johnson promptly after Watkins-Johnson receives an invoice from SVG of
such expenses. The parties agree that nothing in this Section 5 shall shift any
of the responsibility to perfect the transfer of the International Receivables
or the declaration of any dividends that Watkins-Johnson chooses to declare in
order to satisfy its covenant under Section 5.13 of the Purchase Agreement and
to meet the condition set forth in Section 6.2(n) of the Purchase Agreement from
Watkins-Johnson to SVG. To the extent that any of the obligations under this
Section 5 cannot be performed under applicable laws in any jurisdiction, SVG and
Watkins-Johnson shall in good faith determine a means of achieving the intent of
this Section 5 with respect to such obligations that is in compliance with all
such applicable laws. To the extent that any of the obligations of SVG in this
Section 5 are required to be performed by any of the SEG International Entities
after the Closing, SVG shall direct such SEG International Entity to perform
such obligations as required with respect to SVG hereunder.

        6.      Subject to the other obligations set forth in this Amendment, as
of the date of the Closing, all of each of the SEG International Entity's
payables to Watkins-Johnson are hereby cancelled or contributed to such entity's
capital accounts.

        7.      Notwithstanding the language set forth in the grant deed from
Watkins-Johnson to SELCO concerning property located in Scotts Valley,
California more particularly described in Exhibit A to said grant deed (the
"SCOTTS VALLEY PROPERTY"), to the effect that the conveyance of said Property is
subject to all liens and encumbrances of record, Watkins-Johnson and SVG hereby
affirm and agree that all of the obligations of Watkins-Johnson concerning the
Scotts Valley Property which are set forth in or arise under the Purchase
Agreement, including without limitation those obligations arising under Sections
1.1, 2.6, 2.9, 2.11, 2.16, 2.17, 2.23, 4.1, and 7.1 of the Purchase Agreement,
continue in full force and effect, are unaffected by the acceptance of the
aforesaid grant deed by SELCO and are not terminated or diminished by the close
of escrow for sale of the Scotts Valley Property by Watkins-Johnson to SELCO, as
the assignee purchaser for SVG. Watkins-Johnson also acknowledges and agrees
that notwithstanding the sale of the Scotts Valley Property by Watkins-Johnson
to SELCO, SELCO's acceptance of the grant deed, and SVG's leasing of the Scotts
Valley Property from SELCO, the SVG Indemnified Parties retain their rights to
make claims under Section 7.1 of the Purchase Agreement respecting the matters
described on Schedule B of the Pro Forma Title Policy for the Scott Valley
Property. However, nothing in this Amendment shall be construed as establishing
that any representations, warranties or covenants in the Purchase Agreement have
been breached or have not been breached. Nor shall any aspect of this Amendment
be adduced as evidence of any such breach or non-breach.

        8       This Amendment shall be governed by California law and may be
executed in counterparts, each of which shall be deemed an original, and all of
which shall constitute one instrument.

        9.      Except as expressly amended by this Amendment, all provisions of
the Purchase Agreement shall remain in full force and effect.

                                ESCROW AGREEMENT


     THIS ESCROW AGREEMENT (the "ESCROW AGREEMENT") is made and entered into as
of July 6, 1999 by and among Silicon Valley Group, Inc., a Delaware corporation
("BUYER"), and Watkins- Johnson Company, a California corporation (the
"SELLER"), and U.S. Bank Trust National Association, as escrow agent (the
"ESCROW AGENT").


                                    RECITALS

     A.   Buyer and Seller are parties to that certain Securities Purchase
Agreement (the "PURCHASE AGREEMENT"), providing for the acquisition (the
"ACQUISITION") by Buyer of the Semiconductor Equipment Group of Seller.
Capitalized terms used but not defined herein shall have the meanings set forth
in the Purchase Agreement.

     B.   One of the conditions to the closing of the Acquisition, as set forth
in the Purchase Agreement, is the execution and delivery of this Escrow
Agreement.

     C.   Pursuant to Sections 1.5 and 7.5 of the Purchase Agreement, Buyer
shall deposit, or shall cause to be deposited, with the Escrow Agent $3,450,000
in immediately available funds (the "ESCROW AMOUNT") into an escrow fund (the
"ESCROW FUND"). The Escrow Amount will be used to satisfy any potential
indemnification obligations of Seller to any SVG Indemnified Party for Damages
as set forth in Article 7 of the Purchase Agreement.

     D.   This Escrow Agreement sets forth the basis on which the Escrow Agent
will receive and hold, and make disbursements from, the Escrow Fund and the
duties for which the Escrow Agent will be responsible.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties
agree as follows:

     1.   APPOINTMENT. Buyer and Seller appoint Escrow Agent as escrow agent to
serve in such capacity in accordance with the terms and conditions set forth in
this Escrow Agreement. Escrow Agent hereby accepts such appointment.

<PAGE>   2

     2.   PURCHASE AGREEMENT. The Escrow Agent acknowledges receipt of a copy of
the Purchase Agreement; however, except for reference thereto for definitions of
certain words or terms not defined herein, the Escrow Agent is not charged with
any duties or responsibilities with respect to the Purchase Agreement.

     3.   ESCROW AMOUNT. On the Closing Date, Buyer shall deposit, or shall
cause to be deposited, the Escrow Amount directly with the Escrow Agent, the
receipt of which shall be acknowledged to Buyer and Seller, and the same
accepted, by the Escrow Agent as escrow agent hereunder. The Escrow Fund, as
such term is used herein, shall include the Escrow Amount deposited pursuant to
this Section 3 and any interest and earnings thereon, less any payments or
distributions made hereunder.

     4.   INVESTMENT.

          (a)  The Escrow Fund shall be invested by the Escrow Agent, without
distinction as to principal and income, upon receipt of written instructions in
the form attached hereto as Exhibit A executed by one of the officers of Buyer
named in Exhibit B hereto and by one of the officers of Seller named in Exhibit
C hereto, in one or more of the following investments: (i) interest bearing
open-ended or time deposits of any United States bank with assets in excess of
U.S.$500,000,000 (including any affiliate of Escrow Agent that meets such
capital requirements); or (ii) any other investment vehicle pursuant to the
written instructions from Buyer and Seller including, without limitation, money
market and other mutual funds offered or advised by Escrow Agent or any of
Escrow Agent's affiliates. The Escrow Agent shall not be liable for any loss
resulting from any investment made pursuant to written instructions of Buyer and
Seller. Notwithstanding the foregoing, the Escrow Agent shall have the power to
sell or liquidate the foregoing investments whenever the Escrow Agent shall be
required to release all or any portion of the Escrow Fund pursuant to Section 5
hereof. In effecting any such sale or liquidation Escrow Agent may without
inquiry rely upon written instructions from an authorized officer of Buyer (as
set forth on Exhibit B) and Seller (as set forth in Exhibit C), or an successor
of such authorized officer, as to which investments to sell or liquidate.

          (b)  The parties acknowledge that payment of any interest earned on
the funds invested in this escrow will be subject to backup withholding
penalties unless either a properly completed Internal Revenue Service Form W8 or
W9 certification is submitted to Escrow Agent at the time of execution of this
Agreement.

     5.   CLAIMS UPON ESCROW FUND.

          (a)  In the event that any SVG Indemnified Party (an "INDEMNIFIED
PARTY") has a Claim against Seller for which such Indemnified Party desires to
be indemnified as provided in the Purchase Agreement, the Indemnified Party
shall notify Seller of such Claim in accordance with Article VII of the Purchase
Agreement, with a copy to the Escrow Agent, specifying the nature of such Claim
and the amount or the estimated amount thereof to the extent then feasible (the
"CLAIM NOTICE"). If Seller does not notify in writing the Indemnified Party
within thirty (30) days after the date of delivery


                                      -2-

<PAGE>   3


of the Claim Notice that Seller disputes such Claim, with a statement in
reasonable detail (to enable the Indemnified Party to understand the nature of
the dispute) of the basis of such position (a "NOTICE OF OBJECTION"), a copy of
which is delivered to the Escrow Agent, the amount of such Claim shall be
conclusively deemed indemnifiable from the Escrow Account, and the Escrow Agent
shall deliver to the SVG Indemnified Party out of the Escrow Amount cash in an
amount equal to the Damages as specified in the Claim Notice.

          (b)  In case a Notice of Objection is delivered to the Indemnified
Party in accordance with this Section 5, the Indemnified Party shall respond in
a written statement to the Notice of Objection within thirty (30) days and, for
sixty (60) days thereafter, the parties shall attempt in good faith to resolve
such dispute. If the parties should so agree, a memorandum (a "CERTIFICATE OF
RESOLUTION") setting forth such agreement shall be prepared and signed by both
parties, and the Escrow Agent shall be entitled to rely on the Certificate of
Resolution and distribute cash from the Escrow Fund in accordance with the terms
thereof.

          (c)  If the parties do not resolve the dispute within such sixty (60)
day period, either party may demand arbitration of the matter unless the amount
of the Damages is at issue in pending litigation with a third party, in which
event arbitration shall not be commenced until such amount is ascertained or
both parties agree to arbitration. Any arbitration under this Section 5 shall be
conducted in accordance with Section 9.7 of the Purchase Agreement and the
decision of the arbitrators shall be written and shall be supported by written
findings of fact and conclusions which shall set forth the award, judgment,
decree or order (an "AWARD") determined by the arbitrators. The Escrow Agent
shall be entitled to act in accordance with an Award and make or withhold
payments out of the Escrow Fund in accordance herewith.

     6.   ESCROW PROVISIONS.

          (a)  The Escrow Agent may rely without inquiry or investigation and
shall be protected in acting or refraining from acting upon any written notice,
request, waiver, consent, receipt or other paper or document from any officer of
Seller named in Exhibit C or any officer of Buyer named in Exhibit B, not only
as to its due execution and the validity and effectiveness of its provisions,
but also as to the truth of any information therein contained, that the Escrow
Agent in good faith believes to be genuine. The Escrow Agent may disregard any
and all notices or instructions received from any source, except only (i) such
notices or instructions as are specifically provided for in this Agreement or
any other notice signed by Seller and Buyer and (ii) orders or process of any
court entered or issued with or without jurisdiction. If from time to time any
property held pursuant to this Agreement becomes subject to any levy,
attachment, order, judgment, decree, injunction or other judicial,
administrative, or regulatory process ("ORDER"), the Escrow Agent may comply
with any such Order without liability to any person, even though such Order may
thereafter be annulled, reversed, modified or vacated.

          (b)  The Escrow Agent shall not be liable for any error of judgment,
or for any act done or step taken or omitted by it in good faith, or for any
mistake of fact or law, or for anything which it may do or refrain from doing in
connection herewith, except for any liability arising from its own


                                      -3-

<PAGE>   4

gross negligence, willful misconduct or bad faith. In no event shall the Escrow
Agent be liable to any person for punitive, special, indirect or consequential
damages of any kind, even if it is advised of the possibility thereof.

          (c)  The Escrow Agent shall be entitled to consult with counsel, who
may be inside counsel, of its choice with respect to the interpretation of the
provisions hereof, and any other legal matters relating hereto, and shall be
fully protected in taking any action or omitting to take any action in good
faith in accordance with the advice of such counsel.

          (d)  Buyer and Seller jointly and severally agree to indemnify and
hold the Escrow Agent harmless for any and all claims, liabilities, costs,
payments and expenses of Escrow Agent in connection with its performance of its
duties hereunder, including without limitation, reasonable fees and expenses of
counsel for court actions, or for anything done or omitted by it in the
performance of this Escrow Agreement, except as a result of the Escrow Agent's
own gross negligence, willful misconduct or bad faith.

          (e)  All evidence of investment of funds in the Escrow Fund
(including, but not limited to, savings account passbooks, certificates, notes
and other similar items) shall be kept in a place of safekeeping at an office of
the Escrow Agent, or with a safe deposit company, including any such safe
deposit company owned in whole or in part by the Escrow Agent or by any
affiliate of the Escrow Agent. The Escrow Agent shall keep accurate accounts of
all income and interest earned by the funds in the Escrow Fund. Within thirty
(30) days after the close of each calendar month, Escrow Agent shall provide
Seller and Buyer statements on deposits and other investments of the Escrow Fund
in accord with its usual practices.

          (f)  One-half (1/2) of the fees and related expenses of the Escrow
Agent for its services hereunder (including fees and expenses of its legal
counsel) shall be paid by Buyer and one-half (1/2) of such fees and expenses
shall be paid by Seller. Escrow Agent's fees for its duties shall be as set
forth on Exhibit D attached to this Agreement plus reasonable out-of-pocket
costs. Such amounts shall be in addition to other amounts payable by the parties
pursuant to Section 6(d) and other provisions hereof.

          (g)  None of the provisions contained in this Escrow Agreement shall
require the Escrow Agent to advance or risk its own funds in the performance of
its duties herein described.

          (h)  Without limiting the Escrow Agent's rights under any other
provision hereof, whenever the Escrow Agent should receive or become aware of
any conflicting demands or claims with respect to this Agreement or the rights
of any of the parties hereto or any property held hereunder, the Escrow Agent
may without liability refrain from any action until the conflict has been
resolved, or alternatively, may tender into the registry or custody of any court
which the Escrow Agent determines to have jurisdiction all money or property in
its hands under this Agreement, together with such legal pleadings as it deems
appropriate, less a reasonable allowance for its legal fees and expenses, and
thereupon be discharged from all further duties and liabilities under this
Agreement. Any inaction or


                                      -4-

<PAGE>   5

filing of proceedings pursuant to this section shall not deprive the Escrow
Agent of its compensation during such inaction or prior filing.

          (i)  Except as and if specifically provided herein concerning
investments of cash, the Escrow Agent shall have no liability to pay interest on
any money held pursuant to this Agreement. The Escrow Agent may use its own bond
department or any affiliate of Escrow Agent in purchasing or selling securities.
The Escrow Agent shall not be liable for any depreciation or change in the value
of such documents or securities or any property evidenced thereby or for any
losses incurred in liquidating securities or other property to satisfy a
distribution request. All distributions provided for hereunder shall be made by
the Escrow Agent from the Escrow Fund to the extent thereof, subject to
deductions allowed to be made by Escrow Agent as provided elsewhere herein.

          (j)  The Escrow Agent shall not be responsible for any recitals of
fact in this Agreement, or for the sufficiency, form, execution, validity or
genuineness of any documents or securities deposited under this Agreement or for
any signature, endorsement or lack of endorsement thereon, or for the accuracy
of any description therein, or for the identity, authority or rights of the
persons executing or delivering the same or this Agreement.

          (k)  Although the Escrow Agent may demand specific authorizations
(including corporate resolutions, incumbency certificates and the like) or
identification from a party or its representative prior to taking any action
hereunder, no such demand shall constitute a waiver or deprive the Escrow Agent
of the protections afforded by this Agreement.

          (l)  The Escrow Agent shall not be responsible for any delays or
failure to perform caused by circumstances reasonably beyond its control,
including but not limited to: breaches by other parties of their obligations
hereunder; delays by messengers or other independent contractors; mechanical or
computer failures; malfunctioning or breakdowns in public utilities, securities
exchanges, Federal Reserve Banks or securities depositories; interference by
governmental units; strikes, lockouts or civil disobedience; fires or other
casualties; acts of God or other similar occurrences.

     7.   SUCCESSOR ESCROW AGENT. The Escrow Agent, or any successor, may resign
at any time upon giving written notice to Buyer and Seller at least thirty (30)
days before such resignation shall take effect. In addition, Buyer and Seller
may terminate the Escrow Agent's appointment as escrow agent upon giving written
notice (jointly signed by Buyer and Seller) to the Escrow Agent at least thirty
(30) days before such termination shall take effect. If the Escrow Agent shall
resign, be terminated or be unable to serve, then it shall be succeeded by such
bank or trust company jointly named by Buyer and Seller in such thirty (30) day
period, or if no such appointment is made by that time, then it shall be
succeeded by a bank or trust company appointed by a court of competent
jurisdiction upon petition by any of Escrow Agent, Buyer or Seller (in which
action the other parties shall be afforded a reasonable opportunity to
participate) to appoint a successor escrow agent, or the Escrow Agent may tender
the Escrow Fund into court as provided elsewhere in this Agreement. The Escrow
Agent shall transfer the Escrow Fund to its successor and shall thereupon be
discharged from any obligation to perform further services under this Agreement,
and the successor shall thereupon succeed to all of the rights, powers and


                                      -5-

<PAGE>   6

duties and shall assume all of the obligations of the Escrow Agent originally
named in this Escrow Agreement. Notwithstanding any other provision hereof, the
obligation of Buyer and Seller to Escrow Agent under Sections 6(d) and 6(f)
shall survive any resignation or removal of Escrow Agent or any termination of
this Agreement.

     8.   PAYMENT OF TAXES. Watkins-Johnson shall be treated as the owner of the
Escrow Fund for all tax purposes while and to the extent that the Escrow Fund is
held by the Escrow Agent. The Escrow Agent shall furnish such information to the
other parties hereto as shall be requested in writing for tax preparation
purposes by such parties.

     9.   TERMINATION.

          (a)  Unless extended in writing by the parties hereto, the escrow
provided for in this Escrow Agreement shall expire on the later of (i) the
Escrow Release Date, and (ii) the final resolution of, and the final
disbursement of funds to satisfy, any and all Pending Claims (the "TERMINATION
DATE").

          (b)  Promptly following the Escrow Release Date, the Escrow Agent
shall, to the extent funds are available therefor in the Escrow Fund and in the
following order of priority:

               (i)  withhold funds in the Escrow Fund (but not exceeding the
Escrow Amount, when combined with any other sums distributed from the Escrow
Fund to Buyer) in sufficient amount, or to the extent funds are available
therefor, to satisfy the maximum amount of any indemnification obligations of
Seller estimated by Buyer in its written instructions relating to any and all
Pending Claims (which estimate shall be made in good faith by Buyer); and

               (ii) distribute any funds remaining after the allocations and
distributions provided for in clause (i) above to Seller.

          (c)  Promptly following the Termination Date, the Escrow Agent shall,
to the extent funds are available therefor in the Escrow Fund after payment in
satisfaction of any indemnification obligations of Seller pursuant to Section 5,
distribute any remaining funds in the Escrow Fund to Seller.

     10.  GENERAL PROVISIONS.

          (a)  Except as is otherwise required by applicable law, this Agreement
may be amended by the parties hereto at any time by execution of an instrument
in writing signed on behalf of each of the parties hereto.

          (b)  Buyer, on the one hand, and Seller, on the other, may, to the
extent legally allowed, waive compliance with any of the agreements or
conditions for the benefit of such party con tained herein. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in an instrument in writing signed on behalf of such party.

          (d)  The words "include," "includes" and "including" when used herein
shall be deemed in each case to be followed by the words "without limitation."
The headings contained in this Agreement are for reference purposes only and
shall not affect in any way the meaning or interpretation of this Agreement.

          (e)  This Agreement may be executed in one or more counterparts, all
of which shall be considered one and the same agreement and shall become
effective when one or more counterparts have been signed by each of the parties
and delivered to the other party, it being understood that all parties need not
sign the same counterpart.

          (f)  This Agreement, the Purchase Agreement (for purposes of
definition only) and the exhibits hereto, constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

          (g)  Neither this Escrow Agreement nor any beneficial interest therein
may be sold, assigned or otherwise transferred, including by operation of law,
by Buyer or Seller or be taken or reached by any legal or equitable process in
satisfaction of any debt or other liability of Buyer or Seller, except as
provided herein or as would not adversely affect the rights of Seller or Buyer,
respectively, under this Escrow Agreement. Any such attempted transfer in
violation of this Section shall be null and void.

          (i)  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal, void or unenforceable, the remainder of this Agreement will
continue in full force and effect and the application of such provision to other
Persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of such void or unenforceable provision.

          (j)  Except as otherwise provided herein, any and all remedies herein
expressly conferred upon a party will be deemed cumulative with and not
exclusive of any other remedy conferred hereby, or by law or equity upon such
party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

          (k)  This Agreement shall be governed by and construed in accordance
with the laws of California regardless of the laws that might otherwise govern
under applicable principles of conflicts of laws thereof.

          (l)  No provisions of this Agreement are intended, nor shall be
interpreted, to provide or create any third party beneficiary rights or any
other rights of any kind in any client, customer, Affiliate, partner of any
party hereto or any other Person unless specifically provided otherwise herein.

          (m)  Time is of the essence in performing any of the actions
hereunder.
