Item 2.  Acquisition or Disposition of Assets.

         Watkins-Johnson  Company ("WJ") completed the sale of its semiconductor
equipment business  ("Business") to Silicon Valley Group, Inc. "SVG") on July 6,
1999.  More  specifically,  WJ sold to SVG the sole equity interest in a limited
liability company to which WJ had contributed most of the domestic assets of the
Business and also sold SVG the stock of five foreign subsidiaries that engage in
the  Business  abroad.  As part of the  agreement,  WJ sold its  Scotts  Valley,
California  facility to a financial  institution that will lease the facility to
SVG.

         The purchase  price for this  transaction  was  negotiated  with SVG at
arms' length.  It consisted of a number of elements and is subject to adjustment
based on figures for July 2, 1999 that are  expected to be  available by the end
of WJ's third quarter. The purchase price was paid (and will be adjusted) in the
form of:

         (a) cash paid to WJ; (b) the  assumption  by SVG of trade  payables and
accrued  expenses and (c) relief from loan  guarantees  associated with the real
estate and facility used by what had been WJ's semiconductor  equipment business
in Japan. If the measurement  date for the purchase price figures had been March
26, 1999 (i.e.,  the end of WJ's first 1999  quarter),  the purchase price would
have consisted of $12 million cash payable to WJ, relief from loan guarantees of
approximately $20 million of Japanese  indebtedness and the assumption by SVG of
approximately $21 million of WJ trade payables and accrued expenses.

         The agreement provided that WJ retains customer receivables  associated
with the Business. Those receivables totaled approximately $28 million as of the
March 26,  1999 pro forma  financial  statement.  Because  SVG now  employs  the
persons who worked with the Business'  customers,  the  agreement  contractually
obligates  SVG to  use  its  reasonable  commercial  efforts  to  collect  those
receivables on behalf of WJ after the closing.

         Prior to closing this transaction,  the agreement  required that WJ pay
$3.05 million to an environmental consulting firm and an independent third party
escrow holder in connection  with WJ  environmental  monitoring and  remediation
obligations  associated with the Scotts Valley facility.  The $3.05 million will
be used to perform those  obligations and obtain a related insurance policy from
a third party insurance company.

         WJ anticipates that, after the final purchase price is adjusted to July
2, 1999 and transaction expenses are deducted,  this transaction will not result
in a material gain or loss to WJ.

         As part of the SVG  transaction,  WJ made certain  representations  and
warranties to SVG regarding the semiconductor  equipment  business and agreed to
perform certain covenants after the closing.  To support those  representations,
warranties and  covenants,  SVG placed $3.45 million of the purchase price in an
escrow with a third party  escrow  agent.  If and to the extent the funds in the
escrow  account  is not  used  to pay any  claims  SVG  might  assert  during  a
nine-to-twelve-month  post-closing  claims  period,  the  escrowed  amount  plus
interest will be paid to WJ at a future date.  The $3.45  million  figure is not
included in any of the figures set forth in the second paragraph of this Item 2.

         This Item 2 is qualified in its entirety by reference to the agreements
identified in Part (c) of Item 7 of this Form 8-K. Those agreements are filed as
exhibits to this Form 8-K.

(a)  To remove revenues and expenses of SEG operations.
(b)  The SEG  operating  results  reflect a provision for income taxes as if SEG
     was a separate  taxpayer  utilizing  federal and state statutory tax rates.

     for the company without SEG.  Amounts  reflect the adjustment  arising from
     this with and without calculation.

                          SECURITIES PURCHASE AGREEMENT


         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  corporation   ("SVG"),  and  Watkins-Johnson   Company,  a  California
corporation ("Watkins-Johnson").

         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 receipt and sufficiency of which are hereby acknowledged,  the parties agree
as follows:

                                    ARTICLE I
                                 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
or its  subsidiary  (or,  in the  case  of the  Scotts  Valley  Property,  SVG's
designated  assignee),  and SVG or its subsidiary (or, in the case of the Scotts
Valley Property, SVG's


<PAGE>


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>


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>


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>



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."

pursuant to applicable  laws. Each of this Agreement and the Related  Agreements
to be  entered  into by  Watkins-Johnson  pursuant  hereto  have been (or by the

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

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 Acquisition. Schedule 2.4 also identifies the Required Consents (as referred
to in Section  6.1(f) and 6.2(d)) (the  "Required  Consents")  under the caption
"Required Consents."

         2.5  Financial  Statements.  Schedule  2.5  sets  forth  the  unaudited
consolidated  balance  sheet of the  Business  (the "SEG  Balance  Sheet") as of
December  31, 1998 (the "SEG  Balance  Sheet  Date") and the  related  unaudited
statements  of  income  and  cash  flows  for the  12-month  period  then  ended
(collectively, the "SEG Year-End Financials").  Schedule 2.5 also sets forth the
unaudited  consolidated  balance  sheet of the Business as of March 26, 1999 and
the related  unaudited  statements of income for the three (3) month period then
ended  (collectively,  the "SEG Interim  Financials"  and together  with the SEG
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.

<PAGE>


         2.6  No Undisclosed  Liabilities. Except for the Included  Liabilities,
none of the SEG Entities has any liability,  indebtedness,  obligation, expense,
claim,  deficiency,  guaranty  or  endorsement  of any  type,  whether  accrued,
absolute, contingent, matured, unmatured or other (whether or not required to be
reflected  in  financial   statements  in  accordance  with  generally  accepted
accounting  principles) (a "Liability"),  and, to  Watkins-Johnson's  knowledge,
there  is no  reasonable  Basis  for  any  present  or  future  action,  suit or
proceeding,  hearing,  investigation,  charge,  complaint or demand  against the
Business or any SEG Entity giving rise to any Liability,  which  individually or
in the aggregate,  (i) has not been reflected in the SEG Balance Sheet,  or (ii)

                           (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

<PAGE>



with  GAAP  on the SEG  Interim  Financials,  whether  asserted  or  unasserted,

for Taxes since that date other than in the ordinary course of business.

                           (vi)  Watkins-Johnson  and/or the SEG  Entities  have

attributable to Taxes, other than Liens for Taxes not yet due and payable.

                           (viii)  Watkins-Johnson has no knowledge of any Basis

attributable to Taxes which, if adversely  determined,  would result in any Lien

agreement.

                           (xi) No adjustment  relating to any Return of the SEG
Entities (or related to the Included  Assets or the  Business) has been proposed

                           (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.

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

lessor,  the date of the lease,  sublease or other  occupancy  agreement (each a
"Lease"),  and each amendment thereto.  Watkins-Johnson shall have delivered SVG
correct and complete  copies of the Leases  listed on Schedule 2.9. With respect
to each property listed on Schedule 2.9:

                           (i) as to  property  subject  to a Lease,  the  Lease

Watkins-Johnson's knowledge, any other party thereto;

                           (ii) as to  property  held  subject to a Lease,  upon

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

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

(ii)  there  are no  natural  or  artificial  conditions  upon any SEG  Business
Facilities  or any other facts or  conditions  which  could,  in the  aggregate,

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

                  (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

                  (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

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>


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>


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.

                  (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.

                  (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>



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

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

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>


or commitment, whether legally binding or not, to establish any new SEG Employee
Plan, to modify any SEG Employee  Plan (except to the extent  required by law or
to conform any such SEG Employee Plan to the requirements of any applicable law,
in each case as previously  disclosed to SVG in writing,  or as required by this
Agreement),  or to  enter  into  any SEG  Employee  Plan,  nor  does it have any
intention or commitment to do any of the foregoing.

                  (b)  Watkins-Johnson  has  provided  to SVG  (i)  correct  and

relating  to each  SEG  Employee  Plan,  including  but not  limited  to,  trust
agreements, administration service agreements, group annuity contracts and group
insurance  contracts;  (viii)  all  communications  material  to  any  Employees
relating to any SEG Employee Plan and any proposed SEG Employee  Plans,  in each
case,  relating to any amendments,  terminations,  establishments,  increases or
decreases in benefits,  acceleration  of payments or vesting  schedules or other
events which would result in any material  liability to any SEG Entity; and (ix)
all registration  statements and  prospectuses  prepared in connection with each
SEG Employee Plan.

                  (c)  Watkins-Johnson  and each SEG Entity has performed in all
material  respects all obligations  required to be performed by it under, is not
in default or violation of, and  Watkins-Johnson has no knowledge of any default
or violation by any other party to each SEG Employee Plan, and each SEG Employee
Plan has been established and maintained in all material  respects in accordance
with its terms and in compliance  with all applicable  laws,  statutes,  orders,
rules and regulations  (including any applicable exemptions thereto),  including
but not limited to ERISA or the Code;  (ii) each SEG Employee  Plan  intended to
qualify  under  Section  401(a) of the Code and each trust  intended  to qualify
under Section 501(a) of the Code has either  received a favorable  determination
letter with respect to each such Plan from the IRS or has  remaining a period of
time under applicable  Treasury  regulations or IRS  pronouncements  in which to
apply for such a  determination  letter  and make any  amendments  necessary  to
obtain a favorable  determination,  and nothing has  occurred  since the date of
such letter that could  reasonably be expected to affect the qualified status of
such plan; (iii) no "prohibited transaction", within the meaning of Section 4975
of the Code or  Section  406 or 407 of ERISA,  and not  otherwise  exempt  under
Section 408 of ERISA,  or Section 4975 of the Code has occurred  with respect to
any SEG Employee Plan for which any SEG Entity may be liable;  (iv) there are no
actions, suits or claims pending, or, to Watkins-Johnson's knowledge, threatened
or anticipated (other than routine claims for benefits) against any SEG Employee
Plan or against the assets of any SEG Employee  Plan;  and (v) each SEG Employee
Plan can be amended, terminated or otherwise discontinued after the Closing Date
in


                                      -20-

ERISA or Sections 4975 through 4980 of the Code.

                  (d) As of the Closing Date, no SEG Entity has ever maintained,
established, sponsored, participated in, or contributed to, any employee benefit
pension  plan (as defined in Section 3(2) of ERISA) which is subject to Title IV
of ERISA or  Section  412 of the Code  and no SEG  Entity  has or will  have any
liability  to any person for any actions  taken  prior to the Closing  Date with
respect to any  employee  benefit  pension  plan which is subject to Title IV of
ERISA or Section 412 of the Code.

                  (e) At no  time  has  any SEG  Entity  contributed  to or been
obligated to contribute to any  multiemployer  plan (as defined in Section 3(37)
of ERISA) and no SEG Entity has or will have any liability to any person for any
actions  taken prior to the Closing Date with respect to any such  multiemployer
plan.

                  (f) No SEG Employee  Plan  provides,  or has any  liability to
provide,  life  insurance,  medical or other  employee  welfare  benefits to any
employee upon his or her retirement or termination of employment for any reason,
except as may be required by the Consolidated Omnibus Budget  Reconciliation Act
of  1985,  as  amended  ("COBRA"),  or  other  applicable  statute,  and none of
Watkins-Johnson  or any SEG Entity has ever represented,  promised or contracted
(whether  in oral or written  form) to any  employee  of any SEG Entity  (either
individually or to employees as a group) that such employee(s) would be provided
with life  insurance,  medical or other  employee  welfare  benefits  upon their
retirement  or  termination  of  employment,  except to the extent  required  by
statute.

                  (g)  Neither  Watkins-Johnson,  any SEG  Entity  nor any ERISA
Affiliate has violated any of the health care continuation requirements of COBRA
or any similar  provisions  of state law  applicable  to its current,  former or
retired  employees or other "qualified  beneficiaries"  (as that term is defined
pursuant to COBRA) of any SEG Entity.

                  (h) The execution of this  Agreement and the  consummation  of
the transactions contemplated hereby will not (either alone or together with the
occurrence  of  any  additional  or  subsequent  events   contemplated  by  this
Agreement)  constitute an event under any SEG Employee Plan,  trust or loan that
will or may result in any  payment  (whether  of  severance  pay or  otherwise),
acceleration,  forgiveness of indebtedness,  vesting, distribution,  increase in
benefits or obligation  to fund benefits with respect to any current,  former or
retired employee of any SEG Entity.

                  (i) No  payment  or  benefit  which  will  or may be  made  by

payment," within the meaning of Section 280G(b)(1) of the Code.

                  (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>



                           (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

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.

Imported  Goods.  No  penalties  have been  assessed,  asserted or claimed  with
respect to any Imported  Goods.  All Imported Goods have been properly marked as

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

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

GAAP. No product  manufactured,  sold, leased, or delivered by any SEG Entity is

respect to the acquisition or possible  acquisition of Watkins-Johnson  (whether

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

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.

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>


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>


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>


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>


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>


                           (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
incurred in connection with the transfer of any assets by Watkins-Johnson to the
SEG Sub, which Taxes


                                      -37-

<PAGE>


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>


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

be limited to Watkins-Johnson's indemnification obligations in Section 7.1(h).

                  (b) the indemnification  obligations of Watkins-Johnson  under
this  Article 7, shall  terminate at the date that is the later of clause (i) or

and  covenants  specified in clauses  (i)(2) and (i)(3) of this Section  7.3(b),

the date that is the  later of (i) the  Escrow  Release  Date,  except  that the
indemnification  obligations  of SVG to  Watkins-Johnson  set forth in  Sections
7.2(c),  (d) and (e) and  with  respect  to the  covenants  of SVG set  forth in
Section 5.10 (Tax Matters)  shall  terminate upon the expiration of the relevant

                  (d)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  no SVG Indemnified Party shall be entitled to indemnification  under
this Agreement unless and until the sum of all otherwise  indemnifiable  amounts
payable to all the SVG Indemnified  Parties together exceeds $100,000,  in which
case,   subject  to  the  other   provisions  of  this  Agreement,   the  amount
indemnifiable  shall  be the  amount  in  excess  of  $100,000.  Notwithstanding
anything to the contrary in this Agreement, no Watkins-Johnson Indemnified Party
shall be entitled to  indemnification  under this Agreement unless and until the
sum of all otherwise  indemnifiable  amounts payable to all the  Watkins-Johnson
Indemnified  Parties together exceeds  $100,000,  in which case,  subject to the
other provisions of this Agreement, the amount indemnifiable shall be the amount

indemnification  obligations  with respect to the covenants set forth in Section

                  (e)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  Watkins-Johnson  shall  only be  responsible  for lead and  asbestos
abatement  at the  Scotts  Valley  Property  to the  extent set forth in Section
7.1(h).

         7.4   Indemnification   Procedures.   All   claims   or   demands   for
indemnification  under this Article 8 ("Claims")  shall be asserted and resolved
as follows:

                  (a) In the event that any Watkins-Johnson Indemnified Party 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>


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.

         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-

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>


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

herein  shall be  deemed  in each  case to be  followed  by the  words  "without

         9.3  Counterparts.  This  Agreement  may be  executed  in  one or  more

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
the subject matter hereof and , except as otherwise  provided herein,  supersede
all prior  agreements  and  understandings,  both  written  and oral,  among the

the  application  thereof,  becomes  or is  declared  by a  court  of  competent

provision


                                      -52-

<PAGE>


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.

         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

party of any one remedy will not preclude the exercise of any other remedy.

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 acquire the
International  Subsidiary  Capital Stock to one or more of its  subsidiaries and
(b) SVG may  assign  its  rights to acquire  the  Scotts  Valley  Property  to a
subsidiary of SVG or a

Subsidiary  Capital Stock held by  subsidiaries of  Watkins-Johnson  by SVG or a
subsidiary  of SVG and the  purchase of the Scotts  Valley  Property (as defined
below) of Watkins-Johnson by a designee of SVG.

         B. The parties  hereto  desire to amend the  Purchase  Agreement as set
forth in this Amendment.

         NOW,  THEREFORE,  the  parties  hereby  agree  to  amend  the  Purchase
Agreement as follows:

         1. Section 1.4(a) of the Purchase  Agreement is amended and restated to
         read as follows:

         "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  Valuation  Date (as  defined  below),
         determined by Watkins-Johnson based on GAAP, which certificate shall be
         signed by the President or Vice President of  Watkins-Johnson.  As used
         in this Amendment, the term "Valuation Date" shall mean July 3, 1999 at
         12:01  a.m.,  or such other date and time as the  parties  may agree in
         writing.  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  Valuation
         Date, plus the 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 assets and
         liabilities as of December 31, 1998; and, provided,  further,  that the
         inventory

                                      -1-

<PAGE>

         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 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

                                      -2-

<PAGE>

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.

                                      -3-

<PAGE>

         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.

                                      -4-

<PAGE>

         IN WITNESS  WHEREOF,  the parties execute this Amendment as of the date
referred to above.

                                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.

         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.

<PAGE>

         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  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

                                      -2-

<PAGE>

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
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.

                                      -3-

<PAGE>

               (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 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

                                      -4-

<PAGE>

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
duties and shall assume all of the  obligations  of the Escrow Agent  originally

               (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.

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

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.

exclusive of any other remedy  conferred  hereby,  or by law or equity upon such

accordance  with the  laws of  California  regardless  of the  laws  that  might
otherwise govern under applicable principles of conflicts of laws thereof.
