                                     PART I

                                Item I. Business
General

Signal Technology  Corporation (the "Company" or "Signal  Technology")  designs,
develops,  manufactures  and markets  sophisticated  electronic  components  and
subsystems  that are  utilized in a broad range of advanced  defense,  space and
communication  applications.  The Company's  principal strategy for growth is to
acquire complementary  businesses and product lines while aggressively marketing
growth areas in defense, space and communication.  While consolidation continues
in the  defense  industry,  the budget  down cycle  appears to have ended and we
expect to take  advantage  of being one of the  remaining  companies  in defense
electronics.  

   In 1996 the Company acquired certain products lines and associated assets and
backlog of Military  Power  Systems a division of  Transistor  Devices  Inc. The
Company acquired  certain assets and backlog of four companies in 1995:  Western
Microwave,  Inc., Tecnetics  Incorporated,  Adaptive Power Solutions L.L.C., and
Benecia  Communications  Corporation (Benecia  Communications was sold in 1996).
During  1994  the  Company   acquired   the  business  of  Hughes  Power  Supply
Corporation.  

   The Company integrates  acquired  businesses and product lines where possible
with  existing  operations,   reducing  costs  by  eliminating  redundancies  in
administration, operations, facilities and other areas. In addition, the Company
is diversifying its customer base by directing marketing and product development
resources to commercial and  non-military  applications  of its  technologies in
domestic and  international  markets. 

   The Company's core  technology  involves  precision  control,  management and
generation of radio and microwave frequencies and electrical currents. Principal
uses  for the  Company's  products  include  communication  networks,  satellite
communications,  electronic countermeasures,  intelligence and guidance systems.
The Company's major customers are prime government  contractors  which integrate
the  Company's  products  into  complex  systems  sold to agencies of the United
States government and foreign countries.  In recent years, changes in the global
political  situation  have  resulted  in  reductions  in defense  budgets and an
apparent  increase  in  United  States  military  reliance  upon   sophisticated
electronic  equipment.  However, it appears the defense downturn has ceased with
budget  forecasts flat to slightly  increasing in the coming years. In addition,
military  agencies are seeking to maximize  resources by enhancing and upgrading
existing systems and platforms.  The Company believes that its products are well
positioned to take advantage of current  defense  trends due to its  substantial
incumbency  on key existing  programs and  platforms.  The  Company's  operating
strategy of enhancing its manufacturing and engineering  capabilities to improve
product  quality and reduce cost will also enable it to compete  effectively  in
the future.

   The Company  reports its operations  within one principal  industry  segment:
electronic components and equipment.

   During 1996 all of the Company's operating  subsidiaries merged with and into
the Company,  with the Company as the sole surviving  corporation.  Accordingly,
Signal Technology  currently  operates through the former "parent" entity rather
than through various operating subsidiaries.

Products and Customers

The  Company's  products  are  integrated  into complex  electronic  systems and
subsystems that require  precision  generation,  control and management of radio
and microwave  frequencies.  The Company is dedicated to supplying  high quality
products  that meet rigid  customer  requirements  for  performance  and on-time
delivery,  while at the same time being  competitively  priced.  The  Company is
continually  investing  in product  design  and  engineering  capability  and in
state-of-the-art manufacturing and testing systems and processes.

Defense

Signal  Technology  is a leading  supplier  of  sophisticated,  state-of-the-art
electronic  components  and systems for missile  guidance,  airborne  and ground
based radars, electronic countermeasures (ECM), and electronic intelligence. The
Company supplies products on key missiles programs such as the AMRAAM, Tomahawk,
Sparrow,  and  PAC3/Patriot  missile  system.  Key  programs  in ECM include the
ALQ-135,  ALQ-156,  ALQ-184 and ATRJ. The Company  provides  microwave and radio
frequency components and subsystems that primarily generate,  manage and control
frequencies in the range of 1 Khz to 40Ghz. A typical example is a radar jamming
system which  incorporates  a microwave  oscillator  that  generates a signal to
render enemy radar  ineffective.  

   Power supply products are typically used for direct electric  current (DC) to
DC conversion or alternating electric current (AC) to DC conversion, and high or
low voltage power at varied currents.  For example,  power supply products would
be used to convert 400 Hz AC current generated by an aircraft's  generators into
the high voltage high current required for the aircraft's radar.

Space

Signal  Technology  provides  products  for  manned  and  unmanned   spacecraft.
Principal space  applications  include satellite  communications,  intelligence,
surveillance  and  sensing.  The  Company  designs,  develops  and  manufactures
components such as isolators,  circulators and DC to DC power converters for use
on  satellite-based  digital  communication  systems such as Globalstar(TM)  and
Iridium(TM).  Such  systems  are  designed to offer  voice,  data,  paging,  and
facsimile to telephones and data terminals in areas underserved or not served by
existing  systems.  The Company also provides power  converters  currently being
used in the U.S. Air Force MILSTAR II Program.  Substantially all space products
are sold to prime contractors or subcontractors.

Communication

The Company offers a wide selection of communication  products including digital
switching equipment, transceivers, power supplies, and microwave components. The
Company's  communication  products cover a diverse range of applications such as
cellular phone systems,  modems,  air traffic control,  local area and wide area
networks,  digital radios, and intelligence gathering.  Unlike space and defense
electronics  applications,  sales of  communication  products  are  primarily to
commercial  entities,  government  agencies and foreign companies rather than to
prime contractors on specific programs.

   The Company's principal customers are prime contractors and military agencies
of the  United  States  government  and  certain  foreign  countries.  With  the
exception of Raytheon  Company,  which  accounted  for 22%,  14%, and 13% of the
Company's  net  sales in 1996,  1995,  and 1994,  respectively,  the loss of any
customer would not have a material adverse effect on the Company.  

   The  following  table  sets  forth  information  concerning  net sales of the
Company's products to categories of customers and geographic markets.  The sales
information  includes  direct sales by the Company to the customer or market and
indirect sales to prime contractors selling to the customer or market.

================================================================================

Government Contracts

A substantial portion of the Company's business is conducted under United States
government contracts and subcontracts.  These contracts are either competitively
bid or sole source  contracts.  Competitively  bid contracts are awarded after a
formal bid and proposal  competition among suppliers.  Sole source contracts are
awarded when a single  contractor  is deemed to have an expertise or  technology
that is superior to that of competing contractors.


<PAGE>

   Virtually  all  of the  Company's  United  States  government  contracts  and
subcontracts are fixed price contracts,  pursuant to which the Company agrees to
develop a product or to  manufacture a product for a fixed price and assumes the
risk of cost overruns.  Substantially all of the Company's net sales are derived
from fixed price manufacturing  contracts.  The Company's experience is that the
risk of cost overruns is lower on fixed price manufacturing contracts than it is
on fixed price product development contracts.

Sales and Marketing

The Company  markets its  products  through its own sales force and a network of
knowledgeable and active independent sales representatives and distributors. The
Company's  sales force is  comprised of its Vice  President-Marketing,  regional
sales managers,  sales personnel and support staff.  The Company has independent
sales representatives in the U.S. and numerous foreign countries.

   The Company's sales managers are responsible for coordinating the independent
sales  representatives  and for having  extensive  knowledge of  government  and
commercial  programs in their respective  regions.  They also keep the Company's
engineering,  manufacturing and management  personnel advised of possible future
trends  and  requirements  of  customers.  

   The key to the Company's  sales and marketing  strategy is the development of
long-term  relationships  with  its  customers.  This  is  achieved  by  regular
communications  and meetings  between Company  personnel at all levels and their
counterparts  in the customer's  organization.  The Company is active in forming
strategic alliances and buying agreements.  These activities are critical as the
Company intends to acquire other businesses and product lines.

Product Engineering, Manufacturing and Development

The Company  believes that a principal  reason for its success is the quality of
its product design, engineering,  manufacturing and testing capabilities.  These
capabilities  enable the Company to design and  engineer  products  that meet or
exceed its customers'  demanding  specifications for performance and reliability
and to manufacture the products at competitive  prices. The Company has acquired
manufacturing,  engineering  and testing  know-how and  technology in connection
with its  acquisitions  at costs that it believes  are  considerably  lower than
would have been incurred had the Company developed the know-how and technologies
itself.

   The  Company   maintains   engineering,   product  design  and  manufacturing
operations and related  support systems at all of its operating  facilities.  In
addition, all operations utilize computer systems for product design and product
documentation and to control product performance testing. A key to the Company's
ability to reduce  manufacturing  cost has been the  reduction  of direct  labor
through the  introduction  of  automated  or  semi-automated  manufacturing  and
product  testing   systems  and  processes.  

   The Company invests in product development,  principally engineering, to meet
and  anticipate  customer  requirements  for new  products  or  enhancements  of
existing  products.  In  addition,  the  Company  undertakes  customer-sponsored
product   development   contracts.   Accordingly,   the  Company's   development
activities, whether Company-funded or customer-sponsored,  are generally product
or program  specific.  The  amounts  of  Company-funded  and  customer-sponsored
development work performed in each of the last three years are as follows:

================================================================================

Sources of Raw Materials

The  raw  materials  and  sub-components  which  the  Company  requires  for the
manufacture of its products are generally  available from several  sources.  The
Company purchases some raw materials and components from single sources, but has
no reason to believe it could not purchase from alternative sources of supply on
comparable  terms.  From time to time, the Company  experiences  minor delays in
obtaining raw  materials and  components;  however,  delays have not  materially
affected its operations.

Backlog

At December  31, 1996 and 1995,  the  Company  had a backlog of  unshipped  firm
orders of $87,887,000 and $92,837,000, respectively. The Company expects to ship
all of the  December  31, 1996 backlog  within  1997,  except for  approximately
$17,480,000 which will be shipped in later periods.


<PAGE>

Competition

Competition is based primarily on price,  product  performance,  reliability and
customer  support.  The Company believes that it competes  effectively in all of
these areas. The Company's  continued success will depend in part on its ability
to  develop  and  introduce  low  cost,  quality  products  that  meet or exceed
customer's specifications.

   There is no single  competitor  that  competes with the Company in all of its
product  lines.  However,  there  are a  number  of  competitors  in each of the
Company's  product  lines.  Some  of  the  Company's  competitors  have  greater
financial and operating resources than the Company. In addition,  certain of the
Company's  customers have  technological  capabilities in the Company's  product
areas and could choose to manufacture  certain products  themselves  rather than
purchase from suppliers such as the Company.

Employees

As of December 31, 1996, the Company had 993 full-time  employees at its various
divisions and subsidiaries.  No employees are represented by unions. The Company
believes its relations with its employees are satisfactory.

Patents

The Company  holds a number of patents  issued in the United  States and certain
European countries. While the Company considers its patents to be of some value,
its  technological  position depends  primarily on the technical  competence and
creative  ability of its  engineering  staff in the areas of product  design and
manufacturing  processes.  All of the  Company's  key  personnel  are subject to
confidentiality agreements.

Government Regulation

All of the  Company's  operations  are  subject to  compliance  with  regulatory
requirements of federal, state and municipal authorities,  including regulations
concerning employment  obligations and affirmative action,  workplace safety and
protection of the environment.  While compliance with applicable regulations has
not  adversely  affected the Company's  operations in the past,  there can be no
assurance  that the Company will  continue to be in  compliance in the future or
that these regulations will not change.  

   In particular,  the Company must comply with detailed government  procurement
and  contracting   regulations  and  with  United  States  government   security
regulations,   certain  of  which  carry  substantial   penalty  provisions  for
nonperformance or  misrepresentation  in the course of negotiations.  Failure of
the Company to comply with its government  procurement,  contracting or security
obligations  could  result  in  penalties  or  suspension  of the  Company  from
government  contracting,  which  would  have a  material  adverse  effect on the
Company's results of operations.

   The  Company is  required to  maintain a United  States  government  facility
clearance at each of its locations. This clearance could be suspended or revoked
if the  Company  is  found  not to be in  compliance  with  applicable  security
regulations.  Any such  revocation  or  suspension  would  delay  the  Company's
delivery of its products to customers. Although the Company has adopted policies
directed at assuring its compliance with  applicable  regulations and there have
been no suspensions or  revocations  of any of its  facilities,  there can be no
assurance  that the approved  status of the Company's  facilities  will continue
without interruption. United States government regulations require a license for
the export of advanced  weapons  systems.  Changes in United  States  government
policies   towards  the  export  of  these  systems  may  impact  the  Company's
international business.

                               Item 2 Properties

The Company's principal executive offices are located in Sunnyvale,  California.
The Company's principal operating facilities, containing light manufacturing and
associated engineering and support services are located in four states:

Arizona:       The  Company  owns  a  modern  84,260  square  foot  building  in
               Chandler.

California:    The  Company  leases a modern  54,280  square  foot  building  in
               Sunnyvale.  The lease is triple net and expires in November 2003.
               The  current  annual  rent is  $619,000  with an  average  annual
               escalation of approximately 6.6% through the term of the lease.

Florida:       The Company  owns a modern  68,000  square foot  building in Fort
               Walton Beach.

Massachusetts: The Company owns a modern 25,000 square foot building in Webster.
               In  Beverly,  the  Company  leases a modern  40,350  square  foot
               building  under a triple net lease that expires in December 1997.

The Company  believes that its properties  are in good  operating  condition and
repair  and  considers  its  facilities  to be  suitable  and  adequate  for the
Company's  current  and  reasonably  foreseeable  future  activities.  There  is
capacity at the Company's  facilities to absorb acquired  businesses and product
lines. The properties  owned by the Company,  are subject to either mortgages or
industrial revenue bond financing.

                            Item 3 Legal Proceedings

The  Company  is  involved  from time to time in  litigation  incidental  to its
business.

   In April 1996, the Company sold its facility in Weymouth,  Massachusetts  but
retained  the  environmental   liability  and  responsibility   associated  with
groundwater  contaminants present at the site. This facility has been classified
as a tier 1A disposal  site by the  Massachusetts  Department  of  Environmental
Protection  ("DEP"),  as a result of past releases of petroleum  based solvents.
Environmental  assessment reports prepared by independent  consultants  indicate
that  contaminants  present in the Town of Weymouth well field across the street
from the facility are similar to those  reportedly  released at the facility and
still present in the  groundwater at the facility;  however,  these reports also
indicate that the  contaminants  do not exceed safe drinking water levels in the
finished  water  after  normal  treatment.  Other  contaminants  which  did  not
originate at the facility have also been detected in the well field.

   The Company is continuing to conduct  investigations of the facility for soil
and  groundwater  contamination  and  operates  a pilot  remediation  system  in
cooperation with the DEP. It is not possible at this stage of the proceedings to
predict what additional remediation, if any, will be required.

           Item 4 Submission of Matters to a Vote of Security Holders
                                     None.

       Item 7 Management's Discussion and Analysis of Financial Condition
                            and Results of Operations

Overview

The Company's  principal  business is the design,  development,  manufacture and
marketing  of  sophisticated  electronic  components  and  subsystems  that  are
utilized  in  a  broad  range  of  advanced  space,  communication  and  defense
applications.  The  Company's  principal  strategy  for  growth  is  to  acquire
complementary  businesses and product lines while aggressively  marketing growth
areas in space, communication and defense.

Results of Operations for the Years Ended December 31, 1996, 1995 and 1994

Overall, net sales increased  approximately 27% in 1996 as compared to 1995. Net
Sales in defense electronic  applications increased 29% while net sales in Space
and  Communication   grew  94%  and  15%  respectively.   The  sales  growth  is
attributable  to the increased  level of bookings the Company has experienced in
1995 and 1996.

   Net sales  decreased  4% in 1995 as compared to 1994.  The lower level of net
sales in 1995 resulted from the completion of a major missile  supply  contract,
closing of the Company's  Systron Donner  facility,  and the engineering  effort
required prior to entering the production phase on new programs.

<PAGE>

   Gross  profit as a  percentage  of net sales  decreased to 21.7% in 1996 from
21.9% in 1995.  The  slight  decrease  in the  gross  profit  percentage  can be
attributed to higher than expected  costs on development  contracts.  Higher net
sales  accounted  for the increase in the amount of gross profit for 1996.  From
1994 to 1995, gross profit as a percentage of sales dropped from 27.9% to 21.9%.
The  decrease in the gross profit  percentage  can be  partially  attributed  to
difficulty transitioning from longer,  sub-systems contracts to quicker turning,
component  manufacturing at the California facility. In addition, the closure of
the Systron  Donner  facility and  relocation of the business to California  and
Arizona facilities caused slippage in deliveries and subsequent cost overruns in
certain programs. These factors, as well as lower net sales were responsible for
the overall decrease in the amount of gross profit for 1995.

   Selling,  general  and  administrative  expenses  in  1996  increased  $3,022
thousand  (18.6%) as  compared  to a  decrease  in 1995 of $617  thousand  (4%).
However,  as a percentage of sales,  these expenses were 16.9% in 1996, 18.1% in
1995 and  18.1% in 1994.  The  decrease,  as a  percentage  of  sales,  from the
previous  years  resulted  from  economies  of scale which  required  less of an
increase  in  selling,   general  and  administration  expense  to  support  the
significant sales increase for the year.

   Company-funded  research and development  expenses  decreased $1,088 thousand
(68%)  from 1995  levels  as the  development  activities  on  technologies  and
products for use in commercial satellite communication markets were completed in
1995 and the product line was sold in 1996.  In addition the Company was able to
shift the emphasis from  Company-funded  to customer  sponsored R&D.  Customer -
sponsored  R&D  increased  34% to  $4,820  thousand.  Research  and  development
expenses  decreased $781 thousand in 1995 from 1994 levels. The decrease in 1995
was also  attributable  to less  funding  required in the year to  complete  the
development of commercial satellite technologies and product mentioned above.

   In 1995 the Company  recorded a  restructuring  expense  pursuant to the shut
down of its ST Systron Donner facility in Sylmar,  California. The $779 thousand
restructuring expense included employee severance costs, write-down of inventory
and costs  related  to the  consolidation  of the  business  into the  Company's
Chandler, Arizona and Sunnyvale, California facilities.

   Interest expense in 1996 increased to $1,345 thousand from $1,163 thousand in
1995 and $846 thousand in 1994. The increased  interest  expense reflects higher
levels of borrowings  throughout the year as well as higher interest rates.  

   The provision  for income taxes in 1996 was $1,452  thousand on pretax income
of $3,697 thousand.  The effective tax rate was 39.3% in 1996 compared to 118.7%
in 1995  and  39.0%  in  1994.  In 1995 tax on the  pretax  loss  rose  from the
non-deductibility  of goodwill  and  restriction  on carry  forward of state tax
loses.

Liquidity and Capital Resources

The Company's primary source of liquidity in 1996 was cash flow from operations.
Primary  sources of liquidity in 1995 arose from cash flow from  operations  and
bank  borrowings.  In 1994 the  Company's  primary  source of liquidity was bank
borrowings.  The bank  borrowing  arrangement  requires  the Company to maintain
certain minimum balances and ratios,  the most significant of which requires the
maintenance  of a  minimum  net  worth  of $29.5  million.  The  Company  was in
compliance with all covenants at December 31, 1996, and had  approximately  $5.0
million  available for borrowing.  

   At December  31,  1996,  the Company  had working  capital of $31.6  million,
including cash of $1.9 million, as compared to working capital and cash of $30.7
million  and  $1.6  million,   respectively  at  December  31,  1995.  Operating
activities  in 1996  generated  cash  totaling  $6.1 million as compared to $0.8
million in 1995. Investing activities were less than the previous year. In 1996,
cash used for  acquisitions  and associated costs decreased to $1.0 million from
$4.0 million in 1995 and $2.1 million in 1994.

   The  Company   continues  to   investigate   acquisition   opportunities   in
complementary  businesses,  product  lines and markets,  but has no  agreements,
understandings  or  commitments  for additional  acquisitions  at this time. The
Company  believes  that it has  adequate  cash,  working  capital and  available
financing  facilities  to meet its  operating  and capital  requirements  in the
foreseeable future and to continue its acquisition program.

Recent Pronouncements

During October 1996, the AICPA issued Statement of Position 96-1  "Environmental
Remediation  Liabilities"  (SOP  96-1)  which  establishes  guidelines  for  the
recognition,   measurement,   and   disclosure  of   environmental   remediation
liabilities.  It also includes  benchmarks to aid in the  determination  of when
environmental  remediation  liabilities  should be recognized in accordance with
the criteria of Financial  Accounting  Standards  Boards (FASB)  Statement No. 5
"Accounting for  Contingencies"  (SFAS No. 5). The Company does not believe that
adoption of SOP 96-1,  which will become  effective  for fiscal years  beginning
after December 15, 1996, will have material impact on its financial condition or
operating  results.  

   During  February  1997,  the  Financial  Accounting  Standards  Board  issued
Financial  Accounting  Standard  No. 128  "Earnings  per share"  (FAS 128) which
establishes  standards  for  computing  earnings  per  share  ("EPS").  FAS  128
simplifies  the  standards  for  computing  EPS and  makes  them  comparable  to
international  standards. The Company has not yet determined the impact that the
adoption of FAS 128,  which is effective  for  financial  statements  issued for
periods ending after December 15, 1997, will have on its EPS calculation.

1. NATURE OF OPERATIONS

The Company designs, develops, manufactures and markets sophisticated electronic
components  and  subsystems  that are  utilized  in a broad  range  of  advanced
defense, space and communication applications.  The Company's principal strategy
for  growth is to acquire  complementary  businesses  and  product  lines  while
aggressively  marketing growth areas in defense,  space and  communication.  

   The Company's core  technology  involves  precision  control,  management and
generation of radio and microwave frequencies and electrical currents. Principal
uses  for the  Company's  products  include  communication  networks,  satellite
communications,  electronic countermeasures,  intelligence and guidance systems.
The Company's major customers are prime government  contractors  which integrate
the  Company's  products  into  complex  systems  sold to agencies of the United
States government and foreign countries.  The Company believes that its products
are well  positioned  to take  advantage  of current  defense  trends due to its
substantial  incumbency on key existing  programs and  platforms.  The Company's
operating  strategy of enhancing its manufacturing and engineering  capabilities
to  improve  product  quality  and  reduce  cost will also  enable it to compete
effectively  in the  future. 

   The Company  reports its operations  within one principal  industry  segment:
electronic components and equipment.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation

The consolidated  financial  statements include the amounts of Signal Technology
Corporation  and its  wholly-owned  subsidiaries,  which during  1996,  were all
merged with and into the Company.  Intercompany  accounts and transactions  have
been eliminated.

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

Revenue Recognition

The Company records revenue upon shipment or customer acceptance,  in accordance
with the terms of individual  contracts.  Revenue is  determined  based on sales
value per unit and costs are based on  estimated  average cost per unit over the
entire  contract.  Estimated  losses on contracts are  recognized in full in the
period they become known.  Provision is made currently for estimated returns and
warranty costs.

Research and Development

Research and  development  expenditures  are charged to  operations as incurred.
Research and development expenses include  approximately $534 in 1995 and $1,206
in 1994 of funding  provided to Benecia  Communications,  Inc., a company  which
became an operating division of the Company.  Benecia Communications was sold in
May 1996. (See Note 3)

Income Taxes

Deferred tax assets and liabilities consist of differences between the tax basis
of assets and liabilities and their basis for financial  reporting  purposes and
are measured based on the enacted tax rates and laws that will be in effect when
the differences are expected to reverse. Deferred tax assets are stated at their
estimated realizable value. 

The  provision for income taxes  consists of estimated  federal and state income
taxes currently  payable adjusted for changes between periods in the measurement
of  deferred  tax  assets and  liabilities.  Tax  credits  are  recognized  as a
reduction  of income tax expense in the years in which the credits are  utilized
for tax purposes.

Earnings per Share

Earnings per share have been computed  based on the weighted  average  number of
shares of common  stock and common  stock  equivalents  outstanding  during each
period.  Common stock  equivalents  are  included in the per share  calculations
where the effect of their  inclusion  would be dilutive.  Dilutive  common stock
equivalents consist of the incremental common shares issuable upon conversion of
the stock options and warrants using the treasury stock method.

Inventories

Inventories  are  valued  at the  lower of  cost,  determined  by the  first-in,
first-out (FIFO) method,  or market,  and are presented net of progress payments
and foreseeable losses. 
<PAGE>
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                      (in thousands, except per share data)

Property, Plant and Equipment

Property,  plant and equipment are carried at cost, and depreciation is provided
using the  straight-line  method over the estimated useful life of the asset, as
follows:

        Buildings                       33 years
        Building improvements           15 years
        Machinery and equipment         7 years
        Furniture and fixtures          5-7 years

Leasehold  improvements  are amortized  over the lesser of their useful lives or
the life of the  lease.  Maintenance  and  repairs  are  charged  to  expense as
incurred; improvements are capitalized. Upon retirement or sale, the cost of the
assets disposed of and the related accumulated depreciation are removed from the
accounts; any resulting gain or loss is credited or charged to income.

Intangible Assets

Intangible  assets consist  principally of goodwill which is being  amortized on
the straight  line basis over periods of five to twenty  years.  At December 31,
1996 and 1995 accumulated amortization was $888 and $498 respectively.

Concentrations of Risk

A significant  portion of the Company's sales are to customers whose  activities
are related to the defense  industry,  including some who are located in foreign
countries.  The  Company  generally  extends  credit  to  these  customers  and,
therefore,  collection  of  receivables  is  affected  by the  defense  industry
economy. The Company closely monitors extensions of credit, maintaining reserves
for  potential  credit  losses,  and such losses  have been within  management's
expectations. Substantially all of the Company's cash is deposited with a single
bank. 

   The amounts  reported for  receivables  and other  financial  instruments are
considered to approximate fair values based upon comparable  market  information
available at the  respective  balance sheet dates.  Financial  instruments  that
potentially  subject  the  Company to  concentrations  of credit  risks  consist
principally of cash and note and trade receivables. 

   The Company must comply with detailed government  procurement and contracting
regulations and with United States government security  regulations,  certain of
which   carry   substantial    penalty    provisions   for   nonperformance   or
misrepresentation  in the  course of  negotiations.  Failure  of the  Company to
comply with its  government  procurement,  contracting  or security  obligations
could  result  in  penalties  or  suspension  of  the  Company  from  government
contracting, which would have a material adverse effect on the Company's results
of operations.

   The Company's  inventories include  high-technology parts and components that
may be specialized in nature or subject to rapid technology obsolescence.  While
the  Company  has  programs to minimize  the  required  inventories  on hand and
considers  technology  obsolescence  in estimating  reserves to reduce  recorded
amounts to market values, such estimates could change in the future.

Recent Pronouncements

During October 1996, the AICPA issued Statement of Position 96-1  "Environmental
Remediation  Liabilities"  (SOP  96-1)  which  establishes  guidelines  for  the
recognition,   measurement,   and   disclosure  of   environmental   remediation
liabilities.  It also includes  benchmarks to aid in the  determination  of when
environmental  remediation  liabilities  should be recognized in accordance with
the criteria of Financial  Accounting  Standards  Boards (FASB)  Statement No. 5
"Accounting for  Contingencies"  (SFAS No. 5). The Company does not believe that
adoption of SOP 96-1,  which will become  effective  for fiscal years  beginning
after December 15, 1996, will have material impact on its financial condition or
operating  results.  

   During  February  1997,  the  Financial  Accounting  Standards  Board  issued
Financial  Accounting  Standard  No. 128  "Earnings  per share"  (FAS 128) which
establishes  standards  for  computing  earnings  per  share  ("EPS").  FAS  128
simplifies  the  standards  for  computing  EPS and  makes  them  comparable  to
international  standards. The Company has not yet determined the impact that the
adoption of FAS 128,  which is effective  for  financial  statements  issued for
periods ending after December 15, 1997, will have on its EPS calculation.

Reclassifications

Certain amounts in the financial  statements  have been  reclassified to conform
with the current  year's  presentation.  The  reclassification  had no impact on
previously reported net income.

3. ACQUISITIONS AND DISPOSALS

In December, 1996, the Company paid $2,342 for certain assets and the assumption
of certain  liabilities  of  Military  Power  Systems a division  of  Transistor
Devices Inc.

   In July,  1995, the Company paid $1,292 for certain assets and the assumption
of certain  liabilities  of Western  Microwave,  Inc. In  September,  1995,  the
Company paid $2,528 for certain assets and the assumption of certain liabilities
of Tecnetics,  Incorporated. In October, 1995, the Company paid $250 for certain
assets relating to a power supply contract of Adaptive Power  Solutions,  L.L.C.
The  acquisition  included  assets and the  assumption  of  certain  liabilities
relating to the contract.

   In May,  1994,  the Company paid $2,138 for certain assets and the assumption
of certain liabilities of Hughes Power Supply Corporation.

   Each of these  transactions  was financed with cash with the exception of the
Military Power Systems  transaction  which the seller  financed in the amount of
$946  and is  payable  $473 in June  1997,  and  $473 in  December  1997.  These
transactions  have  been  accounted  for  as  purchases.  The  purchase  prices,
including  costs of $20 in 1996, $95 in 1995 and $62 in 1994 associated with the
acquisitions, have been allocated to the acquired assets and liabilities assumed
based upon their fair value at the  respective  dates of the  acquisitions.  The
results of operations of the acquired businesses since the acquisition dates are
included in the consolidated statements of income.

   Assuming the  acquisitions  described above had been made on January 1, 1995,
the Company's unaudited proforma condensed results of operations would have been
as follows:

                                                --------------------------------
                                                        1996             1995
- --------------------------------------------------------------------------------
Net sales                                           $ 120,241         $ 100,258
Net income (loss)                                   $   2,853         $     (81)
Net income (loss) per share                         $    0.37         $   (0.01)

The proforma results have been prepared for comparative purposes only and do not
purport to be indicative of what would have occurred had the  acquisitions  been
made on January 1, 1995, or of results  which may occur in the future. 

   In April  1995,  the  company  exercised  its option to acquire the assets of
Benecia  Communications  Corporation  (BCC). BCC was a development stage company
performing research and development activities on technologies and products used
in  commercial  satellite  communications.  The  Company  had  funded  BCC since
September  1993.  Consideration  for the  acquisition  was the  forgiveness of a
promissory note in the principal amount of $1,800. In May 1996, the Company sold
the  Benecia  product  lines and  associated  assets to  Communications  & Power
Industries, Inc. for $800.

4. RESTRUCTURING

In 1995 the Company recorded a restructuring expense pursuant to the shutdown of
its  Systron  Donner  facility  in Sylmar,  California.  The $779  restructuring
expense includes severance costs of $225,  write-down of assets of $275, removal
and  transportation  costs  of  $185  and  other  costs  of $94  related  to the
restructuring of the business. As of December 31, 1996, all cash expenditures as
a result of the  restructuring  have been  incurred.  Employees  terminated as a
result of the restructuring totaled 46.

The Massachusetts  Industrial Revenue Bond is collateralized by real estate with
a net book value of $1,244 at  December  31,  1996.  The  Company  has a $15,000
unsecured bank revolving  credit  facility,  (the  "Revolver") and a $4,273 bank
real estate term loan  facility,  (the "Real Estate  Loan")  (collectively,  the
"Agreement").  The Real Estate Loan is  collateralized by real estate with a net
book value of $4,820 at December  31,  1996.  Maturing in June,  2000,  the Real
Estate Loan is payable in quarterly  principal payments of $74, plus interest at
the bank's base rate (8.25% at December  31,  1996),  with the last  installment
equal to the remaining  unpaid loan balance.  The Revolver expires in June 2000,
and amounts may be borrowed,  paid and reborrowed at the election of the Company
through the expiration date. Amounts available under the Revolver are reduced by
actual borrowings and outstanding  letters of credit. The Company has the option
of borrowing under one or more differing  interest rate formulas and at December
31, 1996, the weighted  average interest rate was 7.81%. The Company also pays a
quarterly  commitment  fee at annual rates  ranging from 1/8% to 3/8%  depending
upon the amount of the unused facility.

   The Agreement  contains certain  covenants  related to tangible net worth and
interest coverage, as defined. Default on any covenant may affect the commitment
by the bank to continue to lend under the Agreement and, if not corrected, could
accelerate the maturity of any borrowings  outstanding  under the Agreement.  At
December 31, 1996,  the Company was in  compliance  with all covenants and after
reduction for outstanding letters of credit, had approximately  $5,000 available
for  borrowing  under the  Revolver  portion of the  Agreement.  The  Transistor
Devices  Inc.  note of $946 plus  interest at 8.25% is payable $473 in June 1997
and $473 in December 1997.

10. COMMITMENTS AND CONTINGENCIES

The Company leases real estate and equipment under operating  leases expiring at
various dates through  September  2003. The leases  include  provisions for rent
escalation,   renewals  and  purchase  options  and  the  Company  is  generally
responsible  for  taxes,  maintenance  and  repairs.  Aggregate  rental  expense
included in  operations  amounted to $915 in 1996,  $1,384 in 1995 and $1,711 in
1994. Future minimum lease payments under noncancelable operating leases with an
initial term exceeding one year are as follows:

                      1997                 $1,020
                      1998                  $ 750
                      1999                  $ 796
                      2000                  $ 789
                      2001                  $ 773
               
The  Company  is  involved  from time to time in  litigation  incidental  to its
business.

   In April 1996, the Company sold its facility in Weymouth,  Massachusetts  but
retained  the  environmental   liability  and  responsibility   associated  with
groundwater  contaminants present at the site. This facility has been classified
as a tier 1A disposal  site by the  Massachusetts  Department  of  Environmental
Protection  ("DEP"),  as a result of past releases of petroleum  based solvents.
Environmental  assessment reports prepared by independent  consultants  indicate
that  contaminants  present in the Town of Weymouth well field across the street
from the facility are similar to those  reportedly  released at the facility and
still present in the  groundwater at the facility;  however,  these reports also
indicate that the  contaminants  do not exceed safe drinking water levels in the
finished  water  after  normal  treatment.  Other  contaminants  which  did  not
originate at the facility have also been detected in the well field.

   The Company is continuing to conduct  investigations of the facility for soil
and  groundwater  contamination  and  operate  a  pilot  remediation  system  in
cooperation with the DEP. It is not possible at this stage of the proceedings to
predict what additional remediation, if any, will be required.

Non-deductible  expense consists  principally of goodwill,  depreciation expense
resulting  from  certain of the  Company's  acquisitions  and other  amounts not
deductible for tax purposes.  The tax effect of temporary  differences that give
rise to the net deferred tax asset and liability are as follows:

12. STOCKHOLDERS' EQUITY

The Company has stock option plans under which a maximum of 3,167 options may be
granted  generally  at prices not less than 100 percent of the fair market value
of the Company's common stock at the date of option grant.  Options vest ratably
over a four to five year  period and expire not more than ten years from date of
grant.  At December  31, 1996,  1,451  shares of common stock were  reserved for
future  issuance  under the  plans  and 502 were  available  for  future  grant.
Additionally,  non-qualified  options  to  purchase  a total of 93 shares of the
Company's common stock have been granted to certain  non-employee  directors and
others.  These  options were  granted at the fair market value of the  Company's
common stock at the date of option grant, vest generally over a five year period
and expire between 1999 and 2001.

   For financial  reporting  purpose only,  certain options granted in 1992 were
accounted  for as if they  had been  granted  at less  than  market  value  when
compared with the value of common stock issued in the Company's  initial  public
offering  in 1993.  Unearned  compensation  related  to these  options  is being
recorded  ratably over the vesting period.  These options,  as well as all other
options  granted prior to the initial  public  offering,  were granted at prices
determined  by the Board of  Directors to be not less than the fair market value
at the date of grant. The increase in available options of 500 shares is subject
to approval of the Stockholders at the 1997 annual meeting.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                     (in thousands, except per share data)

The following  information  concerning  the Company's  stock option and employee
stock  purchase plans is provided in accordance  with SFAS No. 123,  "Accounting
for Stock-Based Compensation." The Company accounts for such plans in accordance
with APB No. 25 and related Interpretations.

   The fair value of each option  grant has been  estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted average
assumptions used for grants in 1996 and 1995:

        Risk-free Interest Rates                  6.20%
        Expected Life                             4.7 Years
        Volatility                                0.70
        Dividend Yield                             -

The weighted  average fair value of those  options  granted in 1996 and 1995 was
$4.51 and $2.49 respectively.


The  following  proforma  income  information  has been  prepared  following the
provisions of SFAS No. 123:

(amounts in thousands except per share data)          1996             1995
- --------------------------------------------------------------------------------
Net income (loss) - proforma                        $   2,045       $   (317)
Net income (loss) per share - proforma              $    0.27       $  (0.05)
- --------------------------------------------------------------------------------

The above proforma effects on income may not be representative of the effects on
net income for future years as option grants  typically  vest over several years
and additional options are generally granted each year.

                       Report of Independent Accountants


To the Board of Directors and Stockholders
Signal Technology Corporation



   We have audited the consolidated financial statements and financial statement
schedule of Signal Technology Corporation listed in Item 14 (a) (1) of this Form
10-K.  These  financial  statements  and  financial  statement  schedule are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial  statements and financial statement schedule based on
our audits.

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
all material respects,  the consolidated financial position of Signal Technology
Corporation  and  Subsidiaries  as of  December  31,  1996  and  1995,  and  the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended  December 31, 1996 in conformity  with generally
accepted  accounting  principles.  In addition,  in our opinion,  the  financial
statement  schedule  referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material aspects,
the information required to be included therein.

Seller  hereunder are subject to the fulfillment to the reasonable  satisfaction
of Seller and its counsel,  at or prior to the Closing  Date,  of the  following
conditions, unless otherwise waived by Buyer in writing:

                  4.1 All  representations  and  warranties of Buyer made herein

the same effect as though such  representations  and warranties had been made on
the Closing Date.

                  4.2  No  action  or  proceeding   shall  be  then  pending  or
threatened before a court or other  governmental body or by any public authority
to restrict or prohibit the acquisition by Buyer of the Assets.

         V.  Conditions  Precedent to Buyer's  Obligations.  The  obligations of

shall be true and accurate in all material  respects as of the Closing Date with
the

                                        4
<PAGE>

same effect as though such  representations  and warranties had been made on the
Closing Date.

                  5.2  No  action  or  proceeding   shall  be  then  pending  or
threatened before a court or other  governmental body or by any public authority
to restrict or prohibit  the sale by Seller or the  acquisition  by Buyer of the
Assets,  or which  could  terminate  or cancel  any of the  contracts,  the work
pursuant to which was then part of a Backlog Job.

         VI. Seller's Continuing Obligations.

                  6.1 Seller shall  authorize Buyer to use and occupy the Plant,
during  the period  from the  Closing  Date until the date upon which  Buyer has
removed all of the Assets  therefrom (the "Move Date"),  all in accordance  with
the provisions of Section 7.4 hereof.

                  6.2 Upon  Buyer's  request at any time  during a period of one
(1) year  following the Closing Date,  Seller shall execute and deliver to Buyer
any documents  not delivered to Buyer on the Closing Date that Buyer  reasonably
requests  from  Seller  for  perfecting  the  transfer of the  Assets  to  Buyer
contemplated by this Agreement.

                  6.3 a) For a  period  of five (5)  years  after  the  Closing,
Seller shall not, directly or indirectly, in any capacity whatsoever, propose to
design or manufacture,  or design or manufacture any products listed in Schedule
6.3,  or any  products  substantially  similar to such  products,  or conduct or
assist  others in  conducting  or be involved or interested in any manner in any
business which is in competition with the developing, manufacturing, production,
distribution, marketing or selling of any such products;

                           b) For a period of two (2) years  after the  Closing,
Seller shall not, directly or indirectly, in any capacity whatsoever:

                                    i)  propose  to  design or  manufacture,  or
design or manufacture any 1power supplies or DC to DC converters used or similar
to those used in the  programs  listed in  Schedule  6.3,  or conduct or assist
others in  conducting or be involved or interested in any manner in any business
which  is  in  competition  with  the  developing,  manufacturing,   production,
distribution, marketing or selling of any such products used or similar to those
used in any of such programs; and

                                    ii) recruit or solicit,  or assist any other
person or party in recruiting  or  soliciting  any  "Employee"  (as  hereinafter
defined), or induce or attempt to induce or assist any other person or entity in
inducing  or  attempting  to  induce  any  Employee  to  terminate  or alter his
relationship with Buyer (collectively  "Recruiting Activity").  For the purposes
of this Section 6.3c),  the term "Employee" shall mean any person who is, on the
Closing Date, an

                                        5
<PAGE>

employee or  consultant  of Seller and who was engaged in any work in connection
with the  Military  Power  Systems  Division of Seller and whose  employment  or
consulting  arrangement  had not been  terminated by Buyer as of the date of any
such Recruiting Activity.

                  6.4  Seller   acknowledges  that  the  business  of  Buyer  is
international in scope, and that  geographical  limitations on the covenants set
forth in this Article VI are therefore not appropriate. Seller acknowledges that
the scope of each of the covenants  contained in Section 6.3 is reasonable as to
time,  area and persons and is  necessary  to protect  the  legitimate  business
interests of Buyer.  Furthermore,  such  covenants will be regarded as divisible
and if any such covenant is found by any court of competent  jurisdiction  to be
unenforceable because it extends for too long a period of time or over too great
a range of activities or persons or in too broad a geographic  area, it shall be
interpreted  to extend over the maximum  period of time,  range of activities or
persons, or geographic area as to which it may be enforceable. The provisions of
this Article VI shall survive the Closing and the termination of the Agreement.

                  6.5 All  commissions  incurred by Seller and which are, or are
to become,  due to  third-party  sales  representatives  of Seller  shall be the
responsibility of Seller, except as specifically  otherwise provided in Section
7.6 below.

         VII. Buyer's Continuing Obligations.

                  7.1 After the  Closing  Date,  Buyer shall make  available  to
Seller  any  books  of  account,  financial  records,  original  bills  of sale,
contracts,  or other written instruments or records delivered to Buyer by Seller
pursuant to this Agreement at any reasonable  time during business hours for any
proper  purpose  (including,  but  not  limited  to,  performing  all  necessary
accounting   functions  in  order  for  Seller  to  prepare  year-end  financial
statements).

                  7.2 Buyer shall honor Seller's  warranty  policy  described on
Schedule  7.2 with  respect to products of Seller  shipped to  customers  within
twelve (12) months  prior to the  Closing in the  ordinary  course of  business;
provided that Buyer shall have no such  obligations  with respect to any cost or
expense of any kind arising out of any design defect,  whether patent or latent,
in any product shipped by Seller at any time, and all of such costs and expenses
shall be borne by  Seller,  but if any of such costs are borne by Buyer they may
be  recovered  by Buyer in any manner,  including,  without  limitation,  offset
against the unpaid balance of the Purchase  Price.  In any case of design defect
hereunder that comes to the attention of Buyer,  Buyer shall give notice thereof
to Seller,  and if, in any such case, in Buyer's reasonable opinion a cost of at
least Five  Thousand  Dollars ($5,000) will  be involved,  Seller shall have the
option  promptly  upon  receipt of such  notice  either to elect to pay the cost
thereof as soon as the same is reasonably  determined or to perform the services
required to

                                        6
<PAGE>

remedy the matter, and in any such event, Seller shall deal directly with Buyer,
and Buyer shall deal with the customer involved therein

                  7.3 Buyer shall have the right granted by Seller in the nature
of a  license  (the  "License")  to use and  occupy  the Plant and to use in the
ordinary  course of business  all of  Seller's  equipment  and other  personalty
located  therein,  during the period from the  Closing  Date until the Move Date
(which Move Date shall,  as  hereinabove  stated,  be within One Hundred  Eighty
(180)  days from the date  hereof) in order that Buyer may use the Assets in the
optimal manner, in its discretion,  from and after the Closing. For such license
Buyer shall pay to Seller Eight  Hundred  Dollars  ($800) per  day (the "License
Fee") commencing on 1 March 1997 and ending on the Move Date. In addition to the
payment of the License  Fee,  during the  License  period,  Buyer shall  perform
normal  maintenance of the Plant, pay the cost of  utilities,  and shall provide
liability  insurance,  in the amounts shown on Schedule 7.3, insuring both Buyer
and Seller. All other costs of ownership  and use of the Plant shall be borne by
Seller.  On the Move Date, the License shall terminate and Buyer shall leave the
Plant "broom clean", and shall leave the said equipment in the same condition as
at the Closing Date,  reasonable wear and tear and damage by casualty  excepted.
Buyer shall indemnify Seller from and against all loss, cost, damage and expense
caused by or  arising  from any act or  omission  to act of Buyer,  its  agents,
employees  and invitees  with respect to such  licensed use of the Plant and the
equipment.

                  7.4 a) As of the Closing Date, Seller shall terminate each and
all of the employees  employed in the Business,  and shown on the list set forth
as part of Schedule 7.4 attached  hereto and made a part hereof  ("Employees  of
the Business"),  and Buyer shall  thereupon,  without  interruption,  employ the
Employees of the Business.

                           b) All costs of any type or  amount,  arising  in any
way from the  employment  of employees  by Seller prior to Closing  shall be the
responsibility of Seller, and Buyer shall have no responsibility therefor.

                           c) Any  employee  of Seller who  is absent  from work
and who is receiving workmen's compensation,  or who is on leave of absence, and
whose name is not on, or expressly  excluded form the list set forth on Schedule
7.4 shall not be one of the Employees of the Business.

                           d) During the period from the Closing  Date until the
Move  Date or that date  which is  thirty  (30)  days  after  the  Closing  Date
(whichever  first occurs)  (hereinafter  called the  "Transition  Period") Buyer
shall  continue to employ,  and to maintain  the payroll with respect to, all of
the Employees of the Business.

                           e)  Effective  at the end of the  Transition  Period,
Buyer shall have the right to terminate Employees of the Business; provided,

                                        7
<PAGE>

however,  that Buyer shall  retain in its employ  thereafter  for such period of
time as Buyer  shall  determine  at least  thirty (30) of the  Employees  of the
Business.  Seller shall  thereupon  assume and be  responsible  for all costs of
severance  pay,   vacation  pay,  health   insurance  until  31  December  1996,
unemployment insurance and costs related thereto,  worker's compensation arising
from  incidents that occurred on or prior to the Closing Date, of each and every
of the Employees of the Business so terminated by Buyer  ("Termination  Costs"),
and Buyer will have no liability therefor.

                           g) If any of such  Termination  Costs  are  borne  by
Buyer,  Seller shall indemnify Buyer with respect thereto in accordance with the
provisions of Article XIII hereof.

                  7.5  Buyer shall pay  commissions due with respect to products
shipped  by Buyer in any Backlog Job in the amounts and to the third-party sales
representatives of Seller listed on Schedule 7.5 attached hereto.

         VIII.   Representations   and  Warranties  of  Seller.   Seller  hereby
represents and warrants to Buyer as follows:

                  8.1  a)  Seller  is  a  corporation  duly  organized,  validly

                           c) The  execution  and delivery of this  Agreement by

list of all  agreements,  contracts  and  commitments,  whether  written or oral
relating to the Business (the  "Material  Contracts")  by which Seller or any of
the Assets is bound.

                           b) Complete  and correct  copies or  originals of all
written  Material  Contracts,  together  with all  amendments  thereto have been

                  8.10 Seller has received no unliquidated  advanced,  milestone

Agreement,  nor any  statement  or  certificate  furnished or to be furnished to
Buyer  pursuant  hereto  or in  connection  with the  transactions  contemplated

omits or will omit to state a material  fact  necessary  to make the  statements
contained therein not misleading.

         IX. Representation and Warranties of Buyer. Buyer hereby represents and
warrants to Seller as follows:

                  9.1 Buyer is a corporation duly organized,  validly  existing,

                  9.2 The  execution  and  delivery  of this  Agreement  and the

terms.

                  9.4 The execution and delivery of this  Agreement by Buyer and
the  consummation  by  Buyer of the  transactions  contemplated  hereby  are not
prohibited  by and do not violate any  provision  of the  organic  documents  of
incorporation  of Buyer,  or  violate  any  provision  of law,  or  violate  any
provision, or result in the breach, of, or accelerate or permit the acceleration
of the performance required by, any term of any contract, agreement, indenture,

                                       10
<PAGE>

mortgage, note, bond, commitment,  license or other instrument to which Buyer is
a party.

                  9.5 No representation  or warranty by Buyer in this Agreement,
nor any statement or certificate furnished or to be furnished to Seller pursuant
hereto or in connection with the transactions  contemplated  hereby,  contain or

         X.  Access and  Information.  Seller  will give to Buyer and its agents
full access during normal  business  hours,  throughout  the period prior to the
Closing,  to such of the  properties,  books,  contracts,  commitments and other
records of Seller  related to the Military  Power Systems  Division of Seller as
Buyer  reasonably  may request.  If the Closing does not take place,  Buyer will
return to Seller all written  material  received  from  Seller  pursuant to such
access.

         XI. Conduct of Business Pending Closing.

                  11.1 Prior to the Closing Seller shall:

                           a) conduct its business  only in the ordinary  course
and in compliance  with  applicable  laws,  and in  furtherance of the foregoing
shall not engage in any  transaction  or make any contract or commitment  except
for full value;

                           b) insure  the items of  tangible  personal  property
included within the Assets against damage or destruction for not less than their
fair market value;

                  11.2 To the  extent  that the  assignment  by  Seller  and the
assumption by Buyer of any Material Contract, or other contract, lease, license,
permit or approval  shall  require  the consent or approval of any third  party,
this  Agreement  shall not constitute an  assignment,  sublease,  subcontract or
assumption  thereof if such attempted  assignment,  sublease or assumption would
constitute a breach thereof.

                  11.3  Until any  novation  agreements  legally  required  with
respect  to  any  Material  Contracts,  or  the  required  consents,  approvals,
novations  or  waivers of  third  parties  with  respect to any other  contract,
lease, license, permit or approval,  have been executed,  Buyer shall perform or
discharge all of such liabilities, responsibilities, obligations and commitments
thereunder,  and shall enjoy all of the rights,  benefits and  entitlements,  of
Seller under same. Pending any novation  agreements  required by law, Seller and
Buyer  shall  take  all  reasonable  action  to  have  Buyer  recognized  by the
respective Government

                                       11
<PAGE>

Seller.

         XII. Bulk Sale.

                  12.1 Seller shall  indemnify and save and hold Buyer  harmless
from any liabilities  arising from the failure of Buyer or Seller to comply with
any bulk sales or similar law  applicable to the  transactions  contemplated  by
this Agreement.

         XIII. Indemnification

                  13.1 Buyer shall defend,  indemnify and hold harmless  Seller,
its employees,  officers,  directors, agents and affiliates from and against any
and all claims,  demands, causes of action, suits,   judgments,  debts, damages,

Seller upon demand for any and all Losses  suffered or incurred by Seller or its
affiliates resulting from or arising out of any of the following:

                           (a) any untrue representation,  breach of warranty or
nonfulfillment  of any covenant or agreement by Buyer contained herein or in any
certificate,  document  or  instrument  delivered  to Seller  pursuant  to or in
connection herewith;

                           (b) any  liabilities of Seller  expressly  assumed by
Buyer pursuant to this Agreement and listed on Schedule 1.2;

                           (c)  incident to any of the  foregoing or incurred in
investigating  or  attempting  to avoid  the same or to  oppose  the  imposition
thereof, or in enforcing this indemnity.

                  13.2 Seller shall defend,  indemnify and hold harmless  Buyer,

                           (a) any untrue representation,  breach of warranty or
nonfulfillment of any covenant by Seller contained herein or in any certificate,
document or  instrument  delivered  to Buyer  pursuant  hereto or in  connection
herewith;

                           b) any finder's fee or brokerage or other  commission
arising by reason of any  services  alleged to have been  rendered  to or at the
instance of Seller with  respect to this  Agreement  or any of the  transactions
contemplated hereby;

                                       12
<PAGE>

                           (c) the  closing of the Plant or the  termination  by
Seller of its employees;

                           d) any claims of  restitution  or  retribution by any
customer,  or any fines or penalties  arising or resulting  from any  proceeding
arising out of facts that arose on or prior to the  Closing  Date now pending or
hereafter  imposed or levied by any competent  entity whether the same is listed
on a Schedule attached hereto or not;

                           e) any costs, whether direct or indirect, of any kind
related to employees now employed by Seller who become employed by Buyer and are
thereafter debarred or otherwise  prohibited by any entity other than Buyer from
working on government contracts, or whose employment is terminated by Buyer as a
result of demands by such an entity;  provided,  however,  that with  respect to
employees now employed by Seller who become employed by Buyer and who spend time
away from work for Buyer, whether in court or otherwise,  in connection with any
legal proceedings related to Seller or its officers, shareholders,  directors or
affiliates, Buyer shall not be indemnified for (i) the cost of the first two (2)
hours per week so spent away from work and (ii) a total of One Thousand  Dollars
($1,000) of expenses incurred by such employees in that regard;

                           f) any curtailment, cancellation or other termination
of any  Material  Contract by any entity  other than Buyer  arising out of facts
that arose on or prior to the Closing Date; and

                           g)  incident to any of the  foregoing  or incurred in
investigating  or  attempting  to avoid  the same or to  oppose  the  imposition
thereof, or in enforcing this indemnity.

                  13.3  The  party  seeking   indemnification   hereunder   (the
"Indemnitee")  shall  give to the party  from  which  indemnification  is sought
hereunder (the "Indemnitor") written notice of any claim which is subject to the
indemnity  obligations  set forth in Section l3.1 or 13.2, as  applicable,  with
sufficient  promptness  so as not to prejudice  the other  party's  interests in
respect of such claim and any obligation of indemnity  arising  therefrom.  Such
notice  shall set forth all facts and other  information  which the party giving
the notice has as to the claim.  The  failure to give  prompt  notice  shall not
affect the rights of the Indemnitee to indemnity  hereunder except to the extent
that such failure either shall have materially  prejudiced the Indemnitor in the
defense of such claim or shall have  increased  the amount of the  obligation of
the Indemnitor.  The Indemnitor  receiving such notice shall, within thirty days
of receipt of such notice,  (a) deny in writing the claim, (b) pay the amount of
the claim if a monetary  amount is involved,  or (c) if a claim of a third party
is involved,  have the right to assume the defense of such claim. The Indemnitor
shall have the exclusive  right to conduct and control,  through  counsel of its
own  choosing,  the defense of any such claim or any action  arising  therefrom,
provided, that in

                                       13
<PAGE>

conducting the defense of any such claim or action,  the Indemnitor  shall,  and
shall cause its counsel to,  consult with the  Indemnitee  and  counsel, if any,
selected  by it  (the  costs  and  fees of  which  counsel  shall  be  borne  by
Indemnitee),  and shall keep such  counsel,  if any,  and the  Indemnitee  fully
advised of the progress  thereof.  If the Indemnitor  fails or refuses to assume
the conduct  and  control of the  defense of any such claim or action,  then the
Indemnitee shall conduct and control such defense; provided, however, that in so
conducting the defense of any such claim or action,  the Indemnitee  shall,  and
shall cause its counsel to,  consult  with the Indemnitor  and counsel,  if any,
selected by it, and shall keep such counsel,  if any, and the  Indemnitor  fully
advised  of  the  progress  thereof.  No  settlement  of  any  claim  for  which
indemnification  is sought  hereunder shall be made without either (x) the prior
written consent of both the Indemnitor and the  Indemnitee,  which consent shall
not be  unreasonably  withheld or delayed,  or (y) the release of the Indemnitee
from all  liability  relating to such claim,  in form and  substance  reasonable
satisfactory to the Indemnitee and its counsel.

                  13.4 In  addition  to  Buyer's  rights of offset  against  the
unpaid portion of the Purchase Price specifically set forth in other Sections of
this Agreement, Buyer has the right to set off against the unpaid portion of the
Purchase  Price any  judgment it may receive for  indemnification  hereunder  in
addition to, and not in  limitation of any other rights Buyer may have at law or
in equity.

                  13.5  The   foregoing   provisions   of  this   Article   XIII
notwithstanding, no claim for indemnification hereunder with respect to breaches
of any  representation  or warranty  provided  in  Sections  8.1 through 8.4 and
Sections  8.6 through  8.11 and  Article IX shall be valid  unless such claim is
made by notice to the  Indemnitor  within two (2) years after the Closing  Date.
Other claims for indemnification may be made at any time.

         XIV Miscellaneous.

                  14.1  Seller and Buyer may amend this  Agreement  at any time,
but only by written instrument duly authorized and executed by each of them.

                  14.2 No waiver of any term,  provision,  or  condition of this
Agreement,  whether by conduct or otherwise, in any one of more instances, shall
be deemed to be, or  construed  as, a further or  continuing  waiver of any such
term, provision,  or condition or of any other term, provision,  or condition of
this Agreement.

                  14.3 If any one or more of the  provisions  contained  in this
Agreement is held for any reason to be invalid, illegal, or unenforceable in any
respect, such invalidity,  illegality,  or unenforceability shall not affect any
other provision hereof and this Agreement shall be construed as if such invalid,
illegal, or unenforceable provision had never been contained herein.

                             Actions After Closing

         5.1 Further Conveyances and Assurances:  After the Closing,  STMA will,
without further cost or expense to, or  consideration  of any nature from Pulau,
execute and  deliver,  or cause to be executed  and  delivered,  to Pulau,  such

completely to sell,  transfer and assign to and fully vest in Pulau ownership to

Closing,  (1)  this  Agreement  shall  not  constitute  or  be  deemed  to be an
assignment  or an  agreement  to  assign  such item if an  attempted  assignment
without such consent or approval, or

                                       12
<PAGE>

an effective waiver thereof,  would constitute a breach of or default under such
item or create in any party  thereto  the right or power to cancel or  terminate
such item,  and (2) STMA will cooperate with Pulau in entering into or effecting
any reasonable  arrangement designed to provide Pulau with the benefit of STMA's
rights under or pursuant to such item, including enforcement (at Pulau's expense

STMA against any other party as Pulau may reasonably request.

         5.3 Access to Former Business  Records:  For a period of five (5) years
following the Closing,  Pulau will retain all business records constituting part

records at reasonable  times and during normal  business  hours at the principal
business  office of Pulau,  or at such other location or locations at which such
business  records may be stored or maintained from time to time, and will permit
such  representatives to make abstracts from, or copies of, any of such records,
or to obtain temporary  possession of any thereof as may be reasonably  required
by STMA at STMA's sole cost and  expense.  During such  period,  Pulau will,  at
STMA's  expense,  cooperate  with  STMA  in  furnishing  information,  evidence,
testimony,  and other  reasonable  assistance  in  connection  with any  action,
proceeding, or investigation relating to STMA's conduct of the Business prior to
the Closing.

         5.4 Customer  Inquiries:  STMA will,  from and after the Closing  Date,
refer to Pulau all customer inquiries,  requests for bids and quotations and the
like as may relate to the Business.

         5.5  Transitional  Assistance:  In the event that Pulau should  request
assistance  of  STMA  personnel  with  respect  to the  shipment  of  inventory,
machinery and equipment and process  technology  transfer or to support  Pulau's
proposal and/or production activity which may be required prior to completion of
shipment of all machinery and equipment to Pulau,  then in such event STMA would
provide all such  assistance to the extent  available and Pulau would  reimburse
STMA, on a monthly basis, amounts set forth in Schedule 5.5 hereto.

                                   ARTICLE VI
                            Covenant Not to Compete

         As a separate  and  independent  covenant,  STMA and Parent agree that,

affiliate of Pulau relating to a Similar Business,  or interfere with or attempt
to interfere  with any officers or employees of Pulau  relating to the Purchased
Assets or of any affiliate of Pulau relating to a Similar Business, or induce or
attempt to induce  any of them to leave the employ of Pulau or of any  affiliate
of Pulau or violate the terms of their  contract with any of them (provided that
STMA has knowledge of such contract.

arising out of or resulting from any of the following:

                  (a) the inaccuracy or falsehood of any representation,  or the
breach  of any  warranty  by Pulau  contained  in this  Agreement  or the  Other
Agreements;

                  (b) the  breach  by Pulau of any  covenant  contained  in this
Agreement or the Other Agreements; and

                  (c) any  failure by Pulau on or after the date of the  Closing
(i) to pay or satisfy,  or to cause to be paid or satisfied,  any of the Assumed
Liabilities  when due and/or payable,  or (ii) to perform any other  obligations
required  to be  performed  by Pulau  pursuant  to this  Agreement  or the Other
Agreements.

         8.2  Indemnification  of Pulau:  STMA will  indemnify,  defend and hold
Pulau and its affiliates and their respective officers, directors and employees,
harmless  from and against any and all  liabilities,  damages,  losses,  claims,
costs and  expenses  (including  reasonable  attorneys'  fees and  court  costs)
arising out of or resulting  from any of the  following:  

                  (a) the inaccuracy or falsehood of any representation,  or the
breach of any warranty by STMA contained in this Agreement, the Other Agreements
or the Schedules hereto;

                  (b)  the  breach  by STMA of any  covenant  contained  in this
Agreement or the Other Agreements; and

                  (c) any failure by STMA (i) to pay or satisfy,  or to cause to

which are not Assumed  Liabilities  hereunder,  when due and payable, or (ii) to
perform any other obligations  required to be performed by STMA pursuant to this
Agreement and the Other Agreements.

         8.3 Procedure for Claims: If either STMA or Pulau (including, in either
case, parent corporations, subsidiaries and affiliates) (the "Claimant") desires
to make a claim  against any party  obligated to provide  indemnification  under
Sections 8.1 or 8.2 hereof, respectively (the

                                       17
<PAGE>

"Indemnitor"),  with  respect  to any  matter  covered  by such  indemnification
obligation, the procedures for making such claim shall be as follows:

                  (a) Third Party  Claims:  If the claim is for  indemnification
with respect to any action, suit, proceeding or demand at any time instituted or
asserted  against,  or made upon,  the  Claimant  by or on the behalf of a third
party (a "Third Party  Claim"),  the Claimant will give prompt written notice to
the Indemnitor of the institution, assertion or making of the Third Party Claim,
and the nature thereof.  Upon delivery of such notice the claim specified herein
shall be deemed to have been made for purposes of this Agreement. The Indemnitor
shall, within ten (10) days after receipt of such notice, give written notice to
the Claimant as to whether or not the Indemnitor  accepts the  responsibility to
defend and  indemnify  Claimant  with respect to the Third Party  Claim.  If the
Indemnitor  accepts the responsibility to defend and indemnify the Claimant with
respect to the Third Party Claim, the Claimant will then grant to the Indemnitor
authority,  and the Indemnitor will defend and proceed,  at its sole expense, to
cure,  defend,  compromise  or settle the Third Party Claim,  in the name of the
Claimant or  otherwise;  provided,  however,  that any such defense of the Third
Party  Claim  shall be  conducted  by  counsel  reasonably  satisfactory  to the
Claimant,  and that the Indemnitor  shall not enter into any final compromise or
settlement  of the Third  Party  Claim  without  the prior  written  consent  to
Claimant.  If the Indemnitor  denies the  responsibility to defend and indemnify
the Claimant with respect to the Third Party Claim,  or if the Indemnitor  fails
to respond in a timely manner to  Claimant's  notice of the Third Party Claim or
fails to proceed in a diligent and timely manner to cure, defend,  compromise or
settle a Third Party Claim for which it has accepted  responsibility pursuant to
the  foregoing  provisions,  the  Claimant  may then,  proceed to cure,  defend,
compromise  or settle such Third Party Claim as it shall in its sole  discretion
deem to be advisable, without prejudice to any right to indemnification Claimant
may have against the Indemnitor with respect  thereto,  whether pursuant to this
Agreement  or  otherwise.  

                  (b)   Non-Third   Party   Claims:   If   the   claim   is  for
indemnification  with respect to a matter  other than a Third Party  Claim,  the
Claimant  will give  timely  written  notice to the  Indemnitor  of such  claim,
setting forth with reasonable  particularity the basis, nature and dollar amount
thereof.  Upon  delivery of such  notice the claim  specified  therein  shall be
deemed to have been made for purposes of this Agreement.  The Indemnitor  shall,
within thirty (30) days after receipt of such notice, give written notice to the
Claimant  as to whether or not the  Indemnitor  accepts  the  responsibility  to
indemnify  Claimant with respect to such claim.  If the  Indemnitor  accepts the
responsibility  to  indemnify  the  Claimant  with  respect to such  claim,  the

                  good  condition and repair,  ordinary wear and tear and damage
                  by fire or other  casualty  excepted.  Lessee  shall  have the
                  right  to  remove   Lessee's  trade   fixtures,   furnishings,
                  equipment and other personal property from the Premises at any
                  time prior to the  expiration  or sooner  termination  of this
                  Lease.

                  If Lessor  fails to perform any of its repair and  maintenance
                  obligations under this paragraph 7, and such failure continues
                  for more than  thirty  (30) days  after  written  notice  from
                  Lessee,  Lessee shall have the right,  but not the obligation,
                  to perform such repairs and/or maintenance. If any repairs are
                  required to the roof of the  Building,  Lessee  shall have the
                  right to perform  such repairs if Lessor fails to do so within
                  ten (10) days after  written  notice  from  Lessee.  In either
                  case,  Lessor shall reimburse  Lessee for the reasonable costs
                  incurred by Lessee to complete such repairs and/or maintenance
                  within  thirty  (30) days after  receipt of  Lessee's  written
                  demand  therefor,   together  with  copies  of  paid  invoices
                  evidencing  the costs  incurred by Lessee.  If Lessor fails to
                  reimburse  Lessee for such costs  within  such thirty (30) day
                  period,  such amount shall accrue interest at the maximum rate
                  permitted by law  from the date of expenditure by Lessee until
                  reimbursed by Lessor. Any repairs and/or maintenance permitted
                  herein shall be performed in a good and workmanlike  manner by
                  licensed  and insured  contractors.  If Lessor  objects to the
                  repairs and/or maintenance performed by Lessee or the expenses
                  incurred  by Lessee in  performing  such  work,  Lessor  shall
                  deliver written notice of Lessor's  objection to Lessee within
                  thirty (30) days after  Lessor's  receipt of Lessee's  invoice
                  evidencing the expenses  incurred by Lessee.  Lessor's  notice
                  shall set forth in reasonable detail Lessor's

                  were not  required or were not Lessor's  obligation  under the
                  terms of this Lease,  and/or the reasons for Lessor's  dispute
                  of the expenses incurred by Lessee in performing such work. If
                  Lessor and  Lessee  fail to resolve  any such  dispute  within
                  thirty (30) days after Lessor has notified  Lessee of Lessor's
                  objections,   the  matter   shall  be   resolved   by  binding
                  arbitration  in accordance  with the  provisions of California
                  Code of Civil Procedure Sections 1280 et seq.

As of the Effective  Date,  paragraph 7.4 shall be deleted and replaced with the
following:

                  Lessor  shall at all  times  maintain  the  roof,  foundation,
                  exterior walls of the Building (excluding interior surfaces of
                  exterior  walls),  and the  structural  condition  of interior
                  loadbearing walls, in good order, condition and repair. Lessor
                  shall  have no  obligation  to  maintain  or repair  any other
                  portion of the Building or the Outside Area.

                  Lessor shall  service all HVAC units in the Building  prior to
                  delivering  possession of the Additional Premises to Lessee so
                  that the HVAC  system  serving the  Building  shall be in good
                  working  order and repair when Lessee  assumes  responsibility
                  for the  maintenance  and repair of HVAC system as provided in
                  paragraph  7.1.  Lessee  shall  have  thirty  (30)  days after
                  possession of the  Additional  Premises is delivered to Lessee
                  to inspect the HVAC system  serving the Building.  If the HVAC
                  system  is not  in  good  operating  condition,  Lessor  shall
                  promptly  perform  such  maintenance  and/or  repairs  as  are
                  necessary  to the  place  the HVAC  system  in good  operating
                  condition. In addition,  prior to delivering possession of the
                  Additional Premises to Lessee, Lessor and Lessee shall inspect
                  the electrical system in the Additional  Premises to determine
                  whether any repairs to such electrical system are necessary to
                  eliminate any electrical  hazards and to determine whether the
                  existing  electrical  system in the  Additional  Premises  was
                  installed in accordance  with  applicable  code  requirements.
                  Based upon the results of such  inspection,  Lessor and Lessee
                  shall agree upon the repairs and/or improvements to be made to
                  the electrical  system in the  Additional  Premises and Lessor
                  shall  perform  such  work  at  Lessor's  expense  as  soon as
                  reasonably possible.

                  Subject to Lessor's  completion  of the  foregoing,  by taking
                  possession of the Additional  Premises  Lessee shall be deemed
                  to have accepted the Additional Premises and all

                                       4
<PAGE>

                  improvements  therein  in their  present  condition,  "as is,"
                  subject to all applicable zoning, municipal,  county and state
                  laws,  ordinances and regulations governing and regulating the
                  use of the  Additional  Premises.  Lessee  acknowledges  that,
                  except as expressly stated herein, neither Lessor nor Lessor's
                  agents  have made any  representation  or  warranty  as to the
                  condition of the Additional Premises nor any representation or
                  warranty  as to  the  present  or  future  suitability  of the
                  Additional  Premises  for the  conduct of  Lessee's  business.
                  Lessee  expressly  waives the  benefit of any  statute  now or
                  hereafter in effect which would  otherwise  afford  Lessee the
                  right to make repairs at Lessor's expense or to terminate this
                  Lease because of Lessor's failure to keep the Premises in good
                  order, condition and repair.

The first two  sentences  of  paragraph  7.5(a)  of the  Lease are  deleted  and
replaced with the following:

                  Lessee shall not,  without  Lessor's  prior  written  consent,
                  which consent shall not be unreasonably  withheld,  delayed or
                  conditioned, make any alterations, improvements, additions, or
                  Utility  Installations,  in, on or about the Premises,  except
                  for  (i)  nonstructural   alterations  not  exceeding  in  the
                  aggregate  $50,000.00  during the term of this Lease, and (ii)
                  alterations,  improvements  or  additions in or to the Outside
                  Area not exceeding in the aggregate $10,000.00 during the term
                  of this Lease. In any event,  whether or not in excess of such
                  amounts, Lessee shall not make any change or alteration to the
                  exterior of the Building nor remove any  landscaping  from the
                  Outside Area without  Lessor's prior written  consent.  Lessor
                  hereby  consents to Lessee's  installation of storage cages in
                  the  Building  and/or the Outside  Area  provided  that Lessee
                  obtains  all   necessary   permits  and   approvals  for  such
                  installation  and installs  such storage  cages in  compliance
                  with all applicable laws.

         6. Property  Insurance.  As of the Effective Date, the third and fourth
sentences of paragraph 8.1 shall be deleted and replaced with the following:

                  Whether the insuring party is the Lessor or the Lessee, Lessee
                  shall,  as additional  rent for the Premises,  pay the cost of
                  all insurance required  hereunder,  except for that portion of
                  the cost attributable to Lessor's liability coverage in excess
                  of $1,000,000 per occurrence. If Lessor is the insuring party,
                  Lessee shall, within ten (10) days following demand by

                                       5
<PAGE>

                  Lessor,  reimburse  Lessor  for the cost of the  insurance  so
                  obtained.

As of the  Effective  Date,  Paragraph  8.3(a) of the Addendum to Lease shall be
deleted.

         7. Real Property Taxes. As of the Effective Date, Paragraph 10.1 of the
Lease  and the  Addendum  to  Lease  shall  be  deleted  and  replaced  with the
following:

                  Lessee  shall  pay  the  real  property  tax,  as  defined  in
                  paragraph 10.2,  applicable to the Premises during the term of
                  this Lease.  All such payments shall be made at least ten (10)
                  days prior to the  delinquency  date of such  payment.  Lessee
                  shall promptly furnish Lessor with satisfactory  evidence that
                  such taxes  have been  paid.  If any such taxes paid by Lessee
                  shall  cover  any  period  of  time  prior  to  or  after  the
                  expiration  of the term hereof,  Lessee's  share of such taxes
                  shall be  equitably  prorated to cover only the period of time
                  within the tax fiscal year during which this Lease shall be in
                  effect,  and  Lessor  shall  reimburse  Lessee  to the  extent
                  required.  If Lessee shall fail to pay any such taxes,  Lessor
                  shall  have the right to pay the same,  in which  case  Lessee
                  shall  repay such  amount to Lessor  with  Lessee's  next rent
                  installment  together  with  interest at the maximum rate then
                  allowable by law.

         8. Utilities. As of the Effective Date, paragraph 11 of the Addendum to
Lease shall be deleted.

         9. Late Charges.  The second  sentence of paragraph 13.4 is deleted and
replaced with the following:

                  Accordingly,  if any payment of rent or any other sum due from
                  Lessee  shall not be received  by Lessor or Lessor's  designee
                  within  seven (7) days after such amount  shall be due,  then,
                  without any requirement for notice to Lessee, Lessee shall pay
                  to Lessor a late charge equal to 6% of such overdue amount.

         10.  Subordination.  Paragraph  30(a) of the Lease is amended by adding
the following as the last sentence of that paragraph:

                  The  nondisturbance  and  recognition   agreement  shall  also
                  provide that, in the event of a foreclosure of the mortgage or
                  deed of  trust,  Lessee  shall  have the  right  to apply  the
                  security   deposit  paid  to  Lessor  by  Lessee  pursuant  to
                  paragraph  5 of the  Lease  against  the rent due for the last
                  month of the term, notwithstanding the fact that the mortgagee
                  or beneficiary or

                                       6
<PAGE>

                  its  successors  or assigns may not have received the security
                  deposit from Lessor.

         11.  Consents.  Paragraph 36 of the Lease is deleted and replaced  with
the following:

                  Except for  paragraph  33 hereof,  wherever  in this Lease the
                  consent of one party is required to an act of the other party,
                  such consent shall not be  unreasonably  withheld,  delayed or
                  conditioned.

         12.  Parking.  Paragraph  48 of the Lease shall be deleted and replaced
with the following:

                  As  of  the  date  that  Lessor  delivers  possession  of  the
                  Additional Premises to Lessee, Lessee shall have the exclusive
                  right to use all parking spaces within the Outside Area of the
                  Premises.

         13. Right of First Refusal. Paragraph 49 of the Lease is deleted.

         14. Lessee's Remedy. The Lease shall be amended by adding the following
as paragraph 52:

                           52.  Lessee's  Remedy.  If,  as  a  consequence  of a
                  default by Lessor  under this Lease,  Lessee  recovers a money
                  judgment against Lessor, such judgment shall be satisfied only
                  out of the proceeds of sale received  upon  execution  of such
                  judgment  and levied  thereon  against  the  right,  title and
                  interest  of Lessor in the  Premises  and out of rent or other
                  income  from  such  property  received  by  Lessor  or  out of
                  consideration  received  by  Lessor  from  the  sale or  other
                  disposition  of all or any part of  Lessor's  right,  title or
                  interest in the Premises,  and neither Lessor nor its partners
                  shall be liable for any deficiency.

         15.  Option  to  Extend.  The Lease  shall be  amended  by  adding  the
following as paragraph 53:

                  53. Option to Extend.

                           53.1 Option  Period.  Provided  that Lessee is not in
                  default  hereunder,  either at the time of  exercise or at the
                  time the extended term commences, Lessee shall have the option
                  to  extend  the  initial  term  of  this  Lease  for  two  (2)
                  additional  periods of five (5) years  each  (each  an "Option
                  Period") on the same terms,  covenants and conditions provided
                  herein,

                                        7
<PAGE>
                  except that upon such renewal the monthly  rent due  hereunder
                  shall be determined  pursuant to Paragraph 53.2.  Lessee shall
                  exercise its option by giving Lessor written  notice  ("Option
                  Notice") at least one hundred  eighty  (180) days but not more
                  than two hundred seventy (270) days prior to the expiration of
                  the initial term of this Lease or the prior Option Period,  as
                  applicable.

                           53.2 Option Period Monthly Rent. The monthly rent for
                  each Option Period shall be determined as follows:

                                    (a) The parties shall have fifteen (15) days
                  after Lessor  receives the Option Notice within which to agree
                  on the monthly  rent for the Option  Period in question  based
                  upon the then fair  market  rental  value of the  Premises  as
                  defined in  Paragraph  53.2(b).  If the  parties  agree on the
                  monthly rent for the Option Period  within  fifteen (15) days,
                  they  shall  immediately  execute an  amendment  to this Lease
                  stating the monthly rent for the Option Period. If the parties
                  are unable to agree on the monthly rent for the Option  Period
                  within  fifteen  (15) days,  then,  the  monthly  rent for the
                  Option  Period shall be the then  current  fair market  rental
                  value  of  the  Premises  as  determined  in  accordance  with
                  Paragraph 53.2(c).

                                    (b) The "then fair  market  rental  value of
                  the Premises"  shall be defined to mean the fair market rental
                  value of the  Premises  as of the  commencement  of the Option
                  Period,  taking into  consideration  the uses permitted  under
                  this Lease,  the  quality,  size,  design and  location of the
                  Premises,  and the rent for  comparable  buildings  located in
                  Sunnyvale.  In no event shall the fair market  monthly  rental
                  value of the Premises  for the Option  Period be less than the
                  monthly rent last payable under the Lease.

                                    (c)   Within   seven  (7)  days   after  the
                  expiration  of the  fifteen  (15)  day  period  set  forth  in
                  Paragraph  53.2(a),  each  party,  at its cost  and by  giving
                  notice  to the  other  party,  shall  appoint  a  real  estate
                  appraiser with at least five (5) years'  full-time  commercial
                  appraisal  experience  in the area in which the  Premises  are
                  located to appraise and set the monthly  rent. If a party does
                  not appoint an appraiser  within ten (10) days after the other
                  party  has  given  notice  of the name of its  appraiser,  the
                  single  appraiser  appointed  shall be the sole  appraiser and
                  shall set the  monthly  rent.  If the two (2)  appraisers  are
                  appointed  by the  parties as stated in this  paragraph,  they
                  shall meet  promptly and attempt to set the monthly  rent.  If
                  they are unable to agree within thirty (30)

                                       8
<PAGE>

                  days after the second appraiser has been appointed, they shall
                  attempt to elect a third appraiser meeting the  qualifications
                  stated in this paragraph  within  ten (10) days after the last
                  day the two (2)  appraisers are given to set the monthly rent.
                  If they are unable to agree on the third appraiser,  either of
                  the parties to this Lease, by giving ten (10)  days' notice to
                  the other party,  can apply to the then Presiding Judge of the
                  Santa Clara County Superior Court for the selection of a third
                  appraiser  who  meets  the   qualifications   stated  in  this
                  paragraph.  Each of the parties shall bear  one-half  (1/2) of
                  the cost of appointing  the third  appraiser and of paying the
                  third appraiser's fee. The third appraiser,  however selected,
                  shall be a person who has not previously acted in any capacity
                  for either party.

                           Within  thirty (30) days after the  selection  of the
                  third  appraiser,  a majority of the appraisers  shall set the
                  monthly  rent. If a majority of the  appraisers  are unable to
                  set the monthly rent within the stipulated period of time, the
                  three (3)  appraisals  shall be added together and their total
                  divided  by three (3);  the  resulting  quotient  shall be the
                  monthly rent.

                           If,  however,  the  low  appraisal  and/or  the  high
                  appraisal  are/is  more than ten percent  (10%)  lower  and/or
                  higher than the middle appraisal, the low appraisal and/or the
                  high appraisal shall be disregarded.  If only one appraisal is
                  disregarded,  the remaining two (2) appraisals  shall be added
                  together  and their total  divided by two (2);  the  resulting
                  quotient  shall be the monthly rent. If both the low appraisal
                  and the high  appraisal  are  disregarded  as  stated  in this
                  paragraph, then only the middle appraisal shall be used as the
                  result of the appraisal.  After the monthly rent has been set,
                  the appraisers  shall  immediately  notify the parties and the
                  parties shall amend this Lease to set forth such amount.

         16. Delay in Possession of Additional  Space.  The Additional  Premises
are currently occupied with a lease that expires on November 30, 1996. If Lessor
is unable to deliver possession of the Additional Premises to Lessee by December
1,  1996,  Lessor  shall  use all  commercially  reasonable  efforts,  including
litigation,  to regain possession of the Additional  Premises as soon as legally
possible.  However,  if for any reason Lessor cannot  deliver  possession of the
Additional  Premises to Lessee by December 1, 1996,  Lessor shall not be subject
