         (Unaudited)

         Note 1 - Interim Period Reporting:

         While  the  information  presented  in  the  accompanying  consolidated
         financial   statements  is  unaudited,   it  includes  all  adjustments
         (consisting only of normal recurring adjustments) which, in the opinion

         Note 3 - Commitments:                           

         During the first  quarter of 1996,  the  Company  and Sony  Corporation
         signed  an  Addendum  #1 to  Supply  Agreement.  Under the terms of the
         Amended Agreement,  among other things, Sony has agreed to increase its
         minimum  order  of  anti-reflective  film  beginning  July 1,  1997 and
         extending  through  December  31,  2000,  and  Southwall  has agreed to
         install any necessary additional  manufacturing  capacity to supply the
         minimum quantities required by this agreement.

         The Company  began  occupying a new leased  facility  located in Tempe,
         Arizona,  on June 27, 1997,  and is currently  installing the equipment
         required for the  manufacturing  of  anti-reflective  film. The Company
         estimates that it will cost  approximately  $14.5 million to equip this
         facility.

         The Company has also secured  financing from a combination of borrowing
         from  lending  institutions  and an equity sale to a major  investor to
         finance  this  expansion  and   anticipated   related  working  capital
         requirements.  On December  16, 1996,  the Company  borrowed $5 million
         from an institutional  lender.  On April 9, 1997, the Company signed an
         agreement with Teijin Limited of Japan  

                                       7

         (Teijin), a major raw material supplier of the Company,  which included
         arrangements  for  additional   financing  for  the  new  manufacturing
         facility  and for related  potential  working  capital  growth.  Teijin
         purchased  667,000  shares of the Company's  common stock at a price of
         $7.50 per  share,  and  guaranteed  a loan  through  Sanwa  Bank for an
         additional  $10  million.  Teijin  also  received  warrants to purchase
         158,000  shares  of  common  stock at a price of $9.00 per share at any
         time  within  three  years  of the  date of the  agreement.  The  stock
         purchase transaction of approximately $5 million was completed on April
         28, 1997. In addition,  a loan  agreement with Sanwa Bank was signed on
         May 2, 1997,  and the Company  received the first $5 million of funding
         on May 6, 1997.  The  remaining $5 million of loan funding is scheduled
         for  November  6, 1997.  The loan is for a period of seven and one half
         (7.5) years,  with a four (4) year interest only grace period,  payable
         semi  annually at an interest rate of BBA Libor,  fixed semi  annually,
         plus seven  sixteenths  percent.  In addition,  a loan guarantee fee of
         nine sixteenths  percent (.5625%) per annum is payable to Teijin on the
         same payment schedule as the loan interest payments.

         Item 2 - Management's  Discussion  and Analysis of Financial  Condition
         and Results of Operations

         Except for the historical  information  contained  herein,  the matters
         discussed in this Form 10-Q Report are forward-looking  statements that
         involve risks and uncertainties, including those discussed below and in
         the  Company's  Annual Report on Form 10-K.  Actual  results may differ
         materially  from  those  projected.  These  forward-looking  statements
         represent the  Company's  judgment as of the date of the filing of this
         From  10-Q  Report.  The  Company  disclaims,  however,  any  intent or
         obligation to update these forward-looking statements.

         General

         The Company  has  experienced  significant  fluctuations  in  quarterly
         results of operations. Revenues have varied from quarter to quarter due
         to the seasonal  buying  patterns  for the  Company's  Heat  Mirror(TM)
         products,  which  typically have been strongest in the second and third
         quarters.  Sales of the  Company's  energy  conservation  products  are
         significantly influenced by the residential and commercial construction
         industries,  and reduction in construction has generally  resulted in a
         reduction  in the  sales of the  Company's  Heat  Mirror  products.  In
         addition,  operating results have  historically  varied from quarter to
         quarter as a function of the  utilization  of the Company's  production
         machines.   Manufacturing   inefficiencies   have   resulted  from  the
         development  and  introduction  of new products and the changing mix of
         products  manufactured.  Primarily as a result of these  factors and in
         view of the Company's  strategy of developing  additional  applications
         for its thin-film technology, and its ongoing practice of upgrading its
         manufacturing   processes,  the  Company  may  continue  to  experience
         quarterly fluctuations in its results of operations.

         The Company  believes  that it must  continue  to increase  revenues to
         remain profitable.  Although the Company is in the process of expanding
         it's  capacity  and is  seeking  to expand  existing  applications,  to
         develop  new  applications  and to  continue  to  expand  international
         marketing and sales efforts, there can be no assurance that the Company
         will be able to continue to increase revenues.  Additionally,  there is
         significant risk inherent in the expansion project currently in process
         and there can be no  assurances  that the Company will be successful in
         completing  this project  when  scheduled  or that  start-up  costs and
         initial  production  will be completed in accordance with the Company's
         current plans.

         Six Months Ended June 29, 1997 and June 30, 1996

         Net  revenue  increased  to $22.5  million  for the first six months of
         1997,  compared to $21.6  million for the similar  period of 1996.  The
         increase  was due  primarily  to a $1.5  million  increase  in sales of
         anti-reflective  film  compared  to the similar  period last year.  Net
         sales of energy conservation products decreased by $.6 million compared
         to the same period last year,  primarily due to  discontinued  products
         which were sold during the first quarter of 1996.

         Cost of sales,  including  Tempe start up costs,  for the first half of
         1997 was 67% of net revenue,  compared to 69% for the similar period of
         1996.  Cost for 1997  includes  approximately  $.5 million or 2% of net
         revenues for start up costs of a new  manufacturing  facility in Tempe,
         Arizona.   The  percentage  decrease  was  primarily   attributable  to
         production  efficiency  improvements  which have  resulted in increased
         throughputs and improved yields from major production equipment on most
         products. Most of these improvements have taken place cumulatively over
         the nine month period  beginning in October 1996

                                       9
<PAGE>

         through June 30, 1997. There were also some  operational  problems that
         occurred  during the first quarter of 1996,  and higher cost of certain
         metals used in the coating  process for most of the Company's  products
         during the first half of 1996.

         Research and development expenses, as a percent of net revenue, were 6%
         for the first six months of 1997, compared to 5% for the similar period
         in 1996.  The absolute  dollars  increased to $1.4 million in 1997 from
         $1.2 million in 1996. The increase was primarily attributable to higher
         new  product  development,   primarily  in  film  for  laminated  glass
         products,  including  film for the  automotive  and  California  Series
         commercial and residential markets.

         Selling,  general  and  administrative  expense,  as a  percent  of net
         revenue, increased to 20% in the first six months of 1997, from 19% for
         the similar  period in 1996.  The  absolute  dollars  increased to $4.5
         million in 1997 from $4.2 million in 1996.  The increase was  primarily
         attributable to increased  headcount to broaden selling coverage and to
         handle   increased  order  processing   requirements,   accompanied  by
         increased advertising and promotions expense.

         Net  interest  income  increased  in 1997  compared  to 1996  due to an
         increased  amount of money invested and to  capitalization  of interest
         expense   related  to  the   construction   in   progress  of  the  new
         manufacturing facility in Tempe.

         As a result  of the  factors  discussed  above,  the  Company  reported
         pre-tax  income  of $1.4  million  for the  first  six  months of 1997,
         compared to pre-tax  income of $1.3  million for the similar  period in
         1996.


         Three Months Ended June 29, 1997 and June 30, 1996

         Net product sales  increased to $11.7 million for the second quarter of
         1997,  compared to $11.0  million for the similar  period of 1996.  The
         increase  was due  primarily  to a $.5  million  increase  in  sales of
         anti-reflective  film and small increases in several other  electronics
         products totaling $.2 million.  Sales of energy  conservation  products
         was essentially flat with the same period last year.

         Cost of sales for the second  quarter  of 1997 was 68% of net  revenue,
         compared to 69% for the similar period of 1996.  Cost for 1997 includes
         approximately $.4 million or 3% of net revenues for start up costs of a
         new  manufacturing  facility  in  Tempe,  Arizona.  Start up costs  are
         expected to increase in the third quarter 1997, and initial  production
         inefficiencies  are also  anticipated  through the end of the year. The
         percentage  decrease  in cost of sales  from 1996,  excluding  start up
         costs, was primarily attributable to production efficiency improvements
         which have  resulted in increased  throughputs  and higher  yields from
         major production equipment on most products. Most of these improvements
         have taken place  cumulatively  over the nine month period beginning in
         October 1996 through June 30, 1997. During the second quarter 1997, the
         Company  absorbed  some  higher  costs  from  inefficiencies  and waste
         resulting  from the scale up for  production  of new  variations of its
         Heat Mirror XIR(TM) product being sold into the automotive window films
         market, which partially offset the improvements  mentioned above. These
         scale up  inefficiencies  are anticipated to continue to some extent at
         least into the third and fourth quarters of 1997.

         Research and development expenses, as a percent of net revenue, were 6%
         for the second  quarter of 1997,  compared to 5% for the similar period
         in 1996. The absolute dollars increased to $.7 million in 1997 from $.6
         million in 1996. The increased  expense was primarily  attributable  to
         higher new product 

                                       10

         development,  primarily in film for laminated glass products, including
         film  for  the  automotive  and   California   Series   commercial  and
         residential markets.

         Selling,  general  and  administrative  expense,  as a  percent  of net
         revenue,  increased to 20% in the second quarter of 1997,  from 19% for
         the similar  period in 1996.  The absolute  dollar  increase  from $2.1
         million in 1996 to $2.4 million in 1997, is primarily  attributable  to
         increased headcount to broaden selling coverage and to handle increased
         order processing requirements, accompanied by increased advertising and
         promotions expense.

         Net  interest  income  increased  in 1997  compared  to 1996  due to an
         increased  amount of money invested and to  capitalization  of interest
         expense   related  to  the   construction   in   progress  of  the  new
         manufacturing facility.

         As a result  of the  factors  discussed  above,  the  Company  reported
         pre-tax income of $.6 million for the second quarter of 1997,  compared
         to pre-tax income of $.8 million for the similar period in 1996.


         Liquidity and Capital Resources

         At June 29, 1997,  the Company's net working  capital was $22.3 million
         compared with $15.8 million at December 31, 1996. On December 16, 1996,
         the  Company  borrowed  $5  million  from an  institutional  lender for
         partial financing of the new manufacturing  facility in Tempe, Arizona.
         On April 9, 1997,  the Company  signed an agreement with Teijin Limited
         of Japan (Teijin), a major raw material supplier of the Company,  which
         included   arrangements   for   additional   financing   for   the  new
         manufacturing  facility  and  for  related  potential  working  capital
         growth.  Teijin purchased  667,000 shares of the Company's common stock
         at a price of $7.50 per share, and guaranteed a loan through Sanwa Bank
         for an  additional  $10  million.  Teijin  also  received  warrants  to
         purchase  158,000  shares of common stock at a price of $9.00 per share
         at any time within three years of the date of the agreement.  The stock
         purchase transaction of approximately $5 million was completed on April
         28, 1997. In addition,  a loan  agreement with Sanwa Bank was signed on
         May 2, 1997,  and the Company  received the first $5 million of funding
         on May 6, 1997.  The  remaining $5 million of loan funding is scheduled
         for November 6, 1997.  The new  manufacturing  facility is currently in
         process  and is on  schedule  for  startup in late  September  or early
         October  1997,  and will be dedicated  initially to the  production  of
         anti-reflective  film product to fulfill the supply requirements of the
         supply agreement with Sony. Prior to the borrowing  required to finance
         the new  facility,  the Company had financed  itself  through cash flow
         from operations and its existing cash balances.

         From  December  31,  1996,  to  June  29,  1997,  cash  and  short-term
         investments  increased by $2.6 million.  Major  increases  were derived
         primarily from  financing  activities,  as stated above,  totaling $9.7
         million, net of debt repayments,  and net income of $1.4 million. Major
         uses of cash were capital  expenditures  of $5.9 million and  increased
         accounts   receivable  by  $2.6  million.   The  increase  in  accounts
         receivable  is  primarily  attributable  to the  increase in  shipments
         billed in June 1997 by $2.0 million compared to December 1996.

         Additions to property and  equipment  were  approximately  $4.6 million
         during the second  quarter of 1997,  including  $4.1 million on capital
         plant and equipment for the new manufacturing facility mentioned above.
         This  brings  the  total   capital   investment  to  date  on  the  new
         manufacturing  facility to $7.5 million,  and the Company currently has
         additional  commitments for  expenditures of  approximately  $4 million
         during 1997 on this project, which when completed is expected to cost a
         total of approximately  $14.5 million.  The Company 

                                       11
<PAGE>

         anticipates  total capital  expenditures of approximately  $2.5 million
         during 1997 for general replacements and discretionary  improvements of
         current facilities.

         At June 29, 1997,  the Company had $10.1 million of cash and short-term
         investments and a $6 million revolving line of credit, which is subject
         to certain financial  covenants,  which at June 29, 1997 restricted the
         amount available to the Company to $3.7 million.  The revolving line of
         credit  expires June 5, 1998,  but may be extended for  additional  one
         year terms with the bank's approval. As of June 29, 1997, there were no
         borrowings under this line of credit. Existing working capital and cash
         generated  from  operations  are expected to be adequate to satisfy the
         Company's capital and operating  requirements of existing facilities at
         least through 1997.

         Debt and equity  financing  concluded in December 1996 and during April
         and May 1997,  mentioned  above, are expected to be adequate to satisfy
         capital and operating requirements of the new manufacturing facility at
         least through 1997.

                            PART II OTHER INFORMATION


         Item 1 Legal Proceedings and Other Matters

         The Company has been named a defendant  in a lawsuit  filed on April 5,
         1996 by one of its  customers in the United States  District  Court for
         the Eastern  District of New York. The lawsuit in federal court alleges
         certain  contractual  violations  by the Company and seeks relief in an
         aggregate  amount in excess of $35 million.  The Company  believes that
         this  lawsuit  is  without  merit  and  intends  to defend  against  it
         vigorously.

         In  addition,  the Company is involved in certain  other legal  actions
         arising in the  ordinary  course of  business.  The  Company  believes,
         however,  that none of these  actions,  either  individually  or in the
         aggregate,  will  have a  material  adverse  effect  on  the  Company's
         business  or  its  consolidated   financial   position  or  results  of
         operations.

              prepayment terms of the loan agreement and letter of guarantee.

a Most Favored Supplier and, during the term of this Agreement,  Southwall shall

                               FAIR RELATIONSHIP

     Nothing in this Agreement  prohibits or restricts any fair and arm's length
competition between the Parties; provided,  however, that if, at any time during
the  term of this  Agreement,  either  Party  becomes  aware  of any  additional
collaboration  opportunity  with regard to film substrate  products,  such Party
shall,  to the extent possible and in accordance with the provision of paragraph

Agreement  shall be  effective  until  the  termination  of the  Loan  Agreement
stipulated in Article 7 hereinabove  or seven (7) years after the effective date

                                       6

owns 5% of the outstanding  Common Stock of Southwall at the time of termination

     The  provisions  of  paragraphs  13.1,  13.3 and  13.6  shall  survive  the

     THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE
     NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE
     SOLD,   OFFERED  FOR  SALE,   PLEDGED,   HYPOTHECATED,   OR  OTHERWISE

     UNDER  THE   SECURITIES   ACT  OF  1933,  OR  AN  OPINION  OF  COUNSEL
     SATISFACTORY  TO THE COMPANY THAT  REGISTRATION  IS NOT REQUIRED UNDER

                                                                      Void after
                                                                    May 30, 2000

                          SOUTHWALL TECHNOLOGIES, INC.
                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

     This Warrant is issued to Teijin Limited by Southwall Technologies, Inc., a
Delaware  corporation  (the  "Company"),  pursuant to the terms of that  certain
Basic  Agreement  Regarding  Stock  Purchase  Between  Southwall and Teijin (the
"Stock Purchase  Agreement")  dated as of April 9, 1997 by and among the Company
and Teijin Limited, a Japanese corporation.

     1. Purchase of Shares.  Subject to the terms and conditions hereinafter set
forth, the holder of this Warrant is entitled, upon surrender of this Warrant at
the principal office of the Company (or at such other place as the Company shall
notify the holder hereof in writing), to purchase from the Company up to 158,000
fully paid and  nonassessable  shares of Common  Stock of the  Company,  as more
fully  described  below.  The shares of Common Stock  issuable  pursuant to this
Section 1 (the "Shares") shall also be subject to adjustment pursuant to Section
8 hereof.

     2.  Purchase  Price.  The purchase  price for the Shares shall be $9.00 per
share.  Such price shall be subject to  adjustment  pursuant to Section 8 hereof
(such  price,  as  adjusted  from  time to time,  is herein  referred  to as the
"Exercise Price").

     3. Exercise  Period.  This Warrant is immediately  exercisable and it shall
remain exercisable until and including May 30, 2000; provided,  however, that in
the event of (a) the sale of all or substantially all the assets of the Company,
or (b) the merger of the Company into or  consolidation  with any other  entity,
this Warrant  shall,  on the date of such event,  no longer be  exercisable  and
become  null and  void.  In the  event  of a  proposed  transaction  of the kind
described  above,  the Company  shall  notify the holder of the Warrant at least
fifteen (15) days prior to the consummation of such event or transaction.




<PAGE>


     4.  Method  of  Exercise.   While  this  Warrant  remains  outstanding  and
exercisable  in accordance  with Section 3 above,  the holder may  exercise,  in
whole or in part, the purchase rights evidenced  hereby.  Such exercise shall be
effected by:

               (i) the  surrender of the Warrant,  together with a duly executed
copy of the  form of  subscription  attached  hereto,  to the  Secretary  of the
Company at its principal offices; and

               (ii)  the  payment  to the  Company  of an  amount  equal  to the
aggregate Exercise Price for the number of Shares being purchased.

     5. Net Exercise.  In lieu of exercising this Warrant by paying the exercise
price in cash,  the holder of this Warrant may elect to receive  shares equal to
the value of this Warrant (or the portion  thereof being  canceled) by surrender
of this Warrant at the principal  office of the Company  together with notice of
such  election,  in which event the Company  shall issue to the holder  hereof a
number of shares of Common Stock computed using the following formula:

                                     Y (A-B)
                                     -------
                             X=         A

          Where

               X--  The  number of  shares  of Common  Stock to be issued to the
                    holder of this Warrant.

               Y--  The number of shares of Common Stock  purchasable under this
                    Warrant.

               A--  The fair market value of one share of the  Company's  Common
                    Stock.

               B--  The  Exercise  Price  (as  adjusted  to  the  date  of  such
                    calculations).

     For  purposes of this  Paragraph  5, the fair market  value of Common Stock
shall mean the average of the closing bid and asked  prices of the Common  Stock
quoted in the over-the-counter market in which the Common Stock is traded or the
closing  price quoted on the Nasdaq Stock Market or on any exchange on which the
Common  Stock is listed,  whichever is  applicable,  as published in the Western
Edition of The Wall Street Journal for the ten trading days prior to the date of
determination  of fair market value (or such shorter period of time during which
such stock was traded over-the-counter or on such exchange). If the Common Stock
is not traded on the over-the-counter  market or on an exchange, the fair market
value shall be the price per share that the Company  could obtain from a willing
buyer  for  shares of Common  Stock  sold by the  Company  from  authorized  but
unissued  shares,  as such  price  shall  be  determined  in good  faith  by the
Company's Board of Directors.

                                       2




<PAGE>


     6.  Certificates  for  Shares.  Upon the  exercise of the  purchase  rights
evidenced by this Warrant,  one or more certificates for the number of Shares so
purchased  shall be issued as soon as practicable  thereafter,  and in any event
within thirty (30) days of the delivery of the subscription notice.

     7. Issuance of Shares.  The Company covenants that the Shares,  when issued
pursuant to the exercise of this Warrant, will be duly and validly issued, fully
paid and nonassessable and free from all taxes,  liens, and charges with respect
to the issuance thereof.

     8.  Adjustment  of Exercise  Price and Number of Shares.  The number of and
kind of  securities  purchasable  upon exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time as follows:

         (a)  Subdivisions,  Combinations  and Other  Issuances.  If the Company
shall at any time prior to the  expiration of this Warrant  subdivide its Common
Stock,  by  split-up  or  otherwise,  or  combine  its  Common  Stock,  or issue
additional  shares of its Common Stock as a dividend  with respect to any shares
of its Common  Stock,  the number of Shares  issuable  on the  exercise  of this
Warrant  shall  forthwith  be  proportionately   increased  in  the  case  of  a
subdivision or stock  dividend,  or  proportionately  decreased in the case of a
combination.  Appropriate  adjustments  shall also be made to the purchase price
payable per share, but the aggregate purchase price payable for the total number
of Shares  purchasable  under this Warrant (as adjusted)  shall remain the same.
Any  adjustment  under this Section 8(a) shall become  effective at the close of
business on the date the subdivision or combination becomes effective,  or as of
the record date of such dividend,  or in the event that no record date is fixed,
upon the making of such dividend.

         (b) Reclassification,  Reorganization and Consolidation. In case of any
reclassification,  capital reorganization,  or change in the Common Stock of the
Company (other than as a result of a subdivision, combination, or stock dividend
provided   for  in  Section  8(a)   above),   then,   as  a  condition  of  such
reclassification, reorganization, or change, lawful provision shall be made, and
duly executed  documents  evidencing  the same from the Company or its successor
shall be  delivered  to the holder of this  Warrant,  so that the holder of this
Warrant shall have the right at any time prior to the expiration of this Warrant
to  purchase,  at a total price equal to that  payable upon the exercise of this
Warrant,  the kind and  amount  of shares  of stock  and  other  securities  and
property receivable in connection with such reclassification, reorganization, or
change  by a  holder  of the same  number  of  shares  of  Common  Stock as were
purchasable   by  the  holder  of  this  Warrant   immediately   prior  to  such
reclassification,  reorganization,  or  change.  In any  such  case  appropriate
provisions  shall be made with  respect to the rights and interest of the holder
of this Warrant so that the  provisions  hereof shall  thereafter  be applicable
with respect to any shares of stock or other securities and property deliverable
upon exercise hereof, and appropriate  adjustments shall be made to the purchase
price per share payable  hereunder,  provided the aggregate purchase price shall
remain the same.

         (c) Notice of Adjustment. When any adjustment is required to be made in
the number or kind of shares purchasable upon exercise of the Warrant, or in the

                                       3




<PAGE>


Exercise  Price,  the Company shall promptly notify the holder of such event and
of the  number  of  shares  of  Common  Stock or other  securities  or  property
thereafter purchasable upon exercise of this Warrant.

     9.  No  Fractional   Shares  or  Scrip.  No  fractional   shares  or  scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant,  but in lieu of such  fractional  shares the Company  shall make a cash
payment therefor on the basis of the Exercise Price then in effect.

     10. No Stockholder  Rights.  Prior to exercise of this Warrant,  the holder
shall not be entitled to any rights of a stockholder with respect to the Shares,
including (without limitation) the right to vote such Shares,  receive dividends
or other  distributions  thereon,  exercise  preemptive rights or be notified of
shareholder  meetings,  and such  holder  shall not be entitled to any notice or
other communication concerning the business or affairs of the Company.

     11.  Successors  and Assigns.  The terms and provisions of this Warrant and
the Stock Purchase Agreement shall inure to the benefit of, and be binding upon,
the Company and the holders hereof and their respective successors and assigns.

     12. Amendments and Waivers. Any term of this Warrant may be amended and the
observance of any term of this Warrant may be waived  (either  generally or in a
particular instance and either retroactively or prospectively), with the written
consent of the Company and the holders of the shares of Common  Stock  issued or
issuable  upon  exercise of this  Warrant.  Any waiver or amendment  effected in
accordance  with this  Section  shall be binding  upon each holder of any Shares
purchased under this Warrant at the time outstanding  (including securities into
which such Shares have been  converted),  each future holder of all such Shares,
and the Company.

                                       4

     13. Transfer Procedure.  Subject to the provisions of applicable securities
laws, and the written consent of the Company, the holder hereof may transfer all
or part of this Warrant or the Shares  issuable upon exercise of this Warrant by
setting  forth the  name,  address  and  taxpayer  identification  number of the

                                   ARTICLE 1

                         REPRESENATIONS AND WARRANTS OF
                                  THE COMPANY

     The Company hereby  represents and warrants that,  except as set forth on a
Schedule of Exceptions (the "Schedule of Exceptions"), which exceptions shall be
deemed to be representations and warranties as if made hereunder:

     1.1  Organization.  The Company is a duly  organized  and validly  existing
corporation in good standing under the laws of the state of Delaware and is duly
qualified or registered to do business as a foreign  corporation  and is in good
standing in each jurisdiction  which requires such qualification or registration
wherein it owns or leases any  material  properties  or  conducts  any  material
business,  except where the failure so to qualify or register  would not, in the
aggregate,  have a material  adverse effect on the Company.  The Company has the
corporate  power and authority to own its properties and conduct its business as
currently conducted.

     1.2 Capitalization.

         (a) The Company has duly  authorized  capital  stock  consisting of (i)
20,000,000  shares of Common Stock,  $0.001 par value, of which 6,538,589 shares
were issued and outstanding on February 28, 1997 and 378,472 shares were held in
treasury, and (ii) 5,000,000 shares of Preferred Stock, none of which are issued
and  outstanding  on the date hereof or held in treasury.  All such  outstanding
shares of Common  Stock are duly  authorized,  validly  issued,  fully  paid and
nonassessable.

         (b) The  Company has the  following  outstanding  securities  which are
convertible into Common Stock as of March 31, 1997: the Convertible Subordinated
Note due May 31, 1999 to Monsanto  Company,  or its  successors  or assigns (the
"Monsanto  Note").  The  Monsanto  Note is in the  amount  of  US$2,650,000  and
convertible,  prior to  repayment,  into shares of  Southwall  common stock at a
conversion  price of  US$10.00  per  share,  subject  to  certain  anti-dilution
adjustments.

         (c) The Company has adopted the following  plans: (i) the Restated 1987
Stock Option Plan;  (ii) the 1987 Employee Stock  Purchase Plan;  (iii) the 1997
Stock  Incentive  Plan;  and (iv) the 1997 Employee  Stock  Purchase  Plan.  The
following  information  is provided as of March 31,  1997.  With  respect to the
Restated 1987 Stock Option Plan, a total of 2,275,000  shares have been reserved
for  issuance,  563,050  shares have been  issued and  1,659,237  shares  remain
subject to outstanding options. With respect to the 1987 Employee Stock Purchase
Plan,  150,000 shares have been reserved for issuance,  125,213 shares have been
issued and no shares remain  available for issuance because such plan terminated
in accordance  with its terms,  as of March 18, 1997.  The 1997 Stock  Incentive
Plan which  supersedes  the  Restated  1987 Stock Option Plan was adopted by the
Board on March 20, 1997 and remains




<PAGE>


subject to stockholder approval and the 1997 Annual Meeting; 400,000 shares have
been reserved for issuance,  and no options have been granted and no shares have
been issued.  With respect to the 1997 Employee Stock  Purchase Plan,  which the
Board  adopted on March 20,  1997 and which  remaining  subject  to  stockholder
approval at the 1997 Annual  Meeting,  100,000  shares  have been  reserved  for
issuance,  and no shares have been issued. All such plans have been described in
a list previously delivered to Teijin (the "Stock Plans").

         (d) All of the issued and  outstanding  securities  of the Company have
been duly  authorized and validly  issued and are fully paid and  nonassessable.
Except  as  described  in this  Section  1.2 or set  forth in a list  previously
delivered  to  Teijin,  there  is no  other  outstanding  voting  stock or other
outstanding rights to acquire voting stock. Except as set forth herein there are
no existing voting trusts,  voting agreements or similar  agreements between the
Company and any of its shareholders.

         (e)  Copies  of the  Company's  Certificate  of  Incorporation  and the
Company's  Bylaws have been  delivered by the Company to Teijin and are complete
and  correct.  The  Company  will  furnish  upon the  request of Teijin true and
correct  copies  of any  amendments  to the  foregoing  instruments  until  this
Agreement is terminated.

     1.3 Subsidiaries.  The only direct or indirect  subsidiaries of the Company
are those named in Exhibit 21 to the  Company's  Annual  Report on Form 10-K for
the fiscal  year ended  December  31,  1996 or a list  previously  furnished  to
Teijin,  and the information  relating to the organization of such subsidiaries,
set  forth in such  list is true and  correct.  Except  as set  forth in the SEC
Documents or a list furnished to Teijin, the Company is, directly or indirectly,
the  record  and  beneficial  owner  of  all of the  outstanding  shares  of the
subsidiaries,  free and clear of any claim, lien,  encumbrance or agreement with
respect thereto,  and no equity  securities of such subsidiaries are required to
be issued by reason of any warrants,  rights,  options,  calls,  commitments  or
other agreements.

     1.4  Authorization  and Approval.  The Company has full corporate power and
authority  to enter  into and  deliver  this  Agreement  and to  consummate  the
transactions  contemplated hereby. The execution,  delivery,  and performance of
this  Agreement  by the  Company  have been  duly  authorized  by all  requisite
corporate action.  This Agreement  constitutes a valid and binding obligation of
the  Company,  enforceable  against  the Company in  accordance  with its terms,
subject to laws of general  application  relating to bankruptcy,  insolveney and
the  relief  of  debtors  and  rules  of  law  governing  specific  performance,
injunctive  relief or other  equitable  remedies,  and to  limitations of public
policy as they may apply to  Section  1.4 of  Exhibit C to this  Agreement.  The
Company  is not a party  to,  subject  to,  or  bound  by any  agreement  or any
judgment, order, writ, injunction, or decree of any court, governmental body, or
arbitrator  which would conflict with or be breached by the execution,  delivery
or  performance  by the Company of this  Agreement  or which  would  prevent the
carrying out of this  Agreement.  The execution  and delivery of this  Agreement
does not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of, or default (with or without notice
or lapse of time, or both), or give rise to a right of termination, cancellation
or acceleration of any obligation or to a loss of a material benefit, under any

                                       2


<PAGE>


provision of the  Certificate of  Incorporation  or Bylaws of the Company or any
mortgage, indenture, lease or other agreement or instrument,  permit, franchise,
license,  judgment,  order, decree, statute, law, ordinance,  rule or regulation
applicable to the Company or its properties or assets, the effect of which would
have a material  adverse  effect on the  Company as a whole or would  materially
impair  or  restrict  the  Company's   power  to  perform  its   obligations  as
contemplated hereby. The Shares, when sold and delivered by the Company and paid
for by Teijin  pursuant  to this  Agreement,  will  have  been duly and  validly
issued,  will be  fully  paid and  nonassessable,  and  will  have  the  rights,
preferences,  privileges  and  restrictions  described  in  the  Certificate  of
Incorporation. The Common Stock issuable upon exercise, of the Warrants has been
duly and validly reserved, and, when issued in compliance with the provisions of
this  Agreement and the Warrant,  will be validly  issued and will be fully paid
and nonassessable.  The issuance and sale of shares of the Shares and Warrant to
Teijin  under  Article  III of the  Agreement  hereof  will not give rise to any
preemptive rights or rights of first refusal on behalf of any person or group.

     1.5 SEC  Filings and  Financial  Statements.  The  Company  has  heretofore
furnished to Teijin copies of its Annual Report on Form 10-K for the fiscal year
ended  December 31, 1996,  and all other  registration  statements,  reports and
proxy  statements  filed  by  the  Company  with  the  Securities  and  Exchange
Commission  ("SEC") on or after January 1, 1996 ("SEC  Documents").  Each of the
SEC  Documents  was  prepared  and  filed  in  substantial  compliance  with the
provisions of the Securities Act, the Exchange Act and the rules and regulations
thereunder.  Each of the SEC  Documents was complete and correct in all material
respects  as of its  date,  and,  as of its date,  did not  contain  any  untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  in which made, not misleading.  The  consolidated  financial
statements and the notes thereto  contained in the SEC Documents are correct and
complete and fairly present the consolidated  financial  position of the Company
and  its  subsidiaries  on the  respective  dates  thereof  and the  results  of
operations for the periods then ended,  and the balance sheets and notes thereto
contained  therein show and properly  reflect all  material  liabilities  of the
Company and its  consolidated  subsidiaries  on the  respective  dates  thereof,
except for various  claims and  lawsuits  against the Company now  pending,  the
total liability from which would not, in the judgment of the Company, materially
adversely affect the business, properties, or financial condition of the Company
and its subsidiaries,  taken as a whole. Each such financial  statement complies
as to form in all material respects with applicable accounting  requirements and
with the published  rules and regulations of the SEC with respect  thereto,  and
was  prepared  in  conformity  with  generally  accepted  accounting  principles
consistently applied (except, in the case of unaudited statements,  as permitted
by the SEC for its Quarterly Reports on Form 10-Q).

     1.6  Litigation.  There is no action,  suit,  proceeding  or  investigation
pending  or  to  Southwall's  knowledge  threatened  against  the  Company  that
questions the validity of this  Agreement,  or the right of the Company to enter
into such agreement,  or to consummate the transactions  contemplated  hereby or
thereby, or that might result,  either individually or in the aggregate,  in any
material adverse changes in the assets, condition, affairs or prospects of the

                                       3


<PAGE>


Company, financially or otherwise, or any change in the current equity ownership
of the Company,

     1.7 No Pending Transactions.  The Company is not a party to or bound by any
agreement (i) to merge or consolidate  with, or acquire all or substantially all
of the  property  and assets  of,  any other  person,  (ii) to sell,  lease,  or
exchange  all or any  substantial  part of its  property and assets to any other
person,  or (iii) except as otherwise  disclosed to Teijin or as contemplated by
this  Agreement,  to issue,  grant or sell any voting stock or rights to acquire
voting stock in any  transaction  where Teijin  would,  upon  completion  of the
transaction, own five percent (5%) or more of all outstanding Voting Stock.

     1.8 No Material Adverse Changes. Except as otherwise disclosed herein or in
the SEC  Documents,  since  December 31,  1996,  there has not been any material
adverse  change in the  financial  condition or in the  operations,  properties,
assets or  liabilities  of the Company and its  subsidiaries,  taken as a whole,
whether or not arising in the ordinary course of business.

     1.9  Dividends.  Since  December  31,  1996,  the  Company has not made any
declaration,  setting aside or payment to the holders of its Common Stock of any
dividends  or other  distributions  in respect of the Common  Stock or agreed to
take any such action (other than repurchases under employee stock plans).

     1.10 Intellectual Property Rights. Except as disclosed in the SEC Documents
filed prior to the execution of this Agreement, to its knowledge the Company and
its  subsidiaries  own or possess  adequate rights to use all material  patents,
trademarks,  trade names,  service marks,  trade  secrets,  copyrights and other
proprietary  industrial  property rights as are necessary in connection with the
business of the Company,  the lack of which would have a material adverse effect
on the Company and its  subsidiaries  taken as a whole, and the Company does not
have any  knowledge  of any  conflict  with the  rights of the  Company  and its
subsidiaries therein or any knowledge of any conflict by them with the rights of
others therein which would have a material adverse effect on the Company and its
subsidiaries taken as a whole.

     1.11 Compliance with Laws. To the Company's best knowledge, the business of
the Company and its subsidiaries is not being conducted in material violation of
any applicable law, rule or regulation  (including  environmental  regulations),
judgment,  decree or order of any  governmental  entity which is material to the
conduct of the Company's business, except for any violations which, individually
or in the  aggregate,  will not have a material  adverse  effect on the business
condition  of the Company and its  subsidiaries  taken as a whole.  There are no
judgments or outstanding orders,  injunctions,  decrees,  stipulations or awards
(whether rendered by a court or administrative agency or by arbitration) against
the Company or any  subsidiary  or against any of the  respective  properties or
business which will,  individually or in the aggregate,  have a material adverse
effect on the business  condition of the Company and its subsidiaries taken as a
whole.

     1.12 Disclosure.

         (a)  No  representation  or  warranty  made  by  the  Company  in  this
Agreement,  and  no  statement  contained  in any  certificate,  list  or  other
instrument  specified  in this  Agreement  (when  read  together  and taken as a
whole),  contains any untrue  statement  of a material  fact or omits to state a
material fact necessary to make the statements  contained herein or therein,  in
light of the circumstances under which they are made, not misleading.

         (b)  Notwithstanding  the  foregoing,  Teijin  shall be  deemed to have
knowledge of all information set forth in the SEC Documents. Any facts disclosed
in the SEC Documents or in response to any particular  representation  contained
herein shall be deemed to have been  disclosed to Teijin in connection  with all
other applicable representations contained herein.

                                   ARTICLE II

                            COVENANTS OF THE COMPANY

     Until the  termination  of this  Agreement  or until Teijin shall no longer
hold 5% of the outstanding  Common Stock of the Company,  the Company  covenants
and agrees as follows:

     2.1 Rule 144.  With a view to making  available  to Teijin the  benefits of
Rule 144  promulgated  under the  Securities  Act,  any other  similar  rules or
regulations of the SEC which may at any time permit Teijin to sell or distribute
without  registration the Shares and shares of Common Stock issued upon exercise
of the Warrant,  the Company agrees to use its best efforts to file with the SEC
in a timely  manner all reports and other  documents  required to be filed under
the Exchange Act.

     2.2 Future SEC Filings. The Company shall promptly provide to Teijin copies
of all SEC Documents  (excluding  exhibits) filed with the SEC after the Closing
Date.

     2.3 Stock Exchange Listing. The Company will use its best efforts to obtain
the listing on the Nasdaq National Market of the Shares and the shares of Common
Stock which Teijin may acquire upon exercise of the Warrant.

                                   EXHIBIT C

                                   ARTICLE I

                              REGISTRATION RIGHTS

     1.1 Rights to Demand Registration.

         (a) If at any time and from  time to time,  Teijin  shall  request  the
Company in writing to register under the Securities Act the Shares or any shares
of Common  Stock  issued  upon  exercise  of the Warrant and held by Teijin (the
shares subject to such request herein referred to as the "Registrable  Shares"),
the Company shall use all  reasonable  efforts to cause the  Registrable  Shares
specified  in such  request  (which  must be at  least  such  percentage  of the
aggregate shares of Common Stock then  outstanding as is reasonably  anticipated
to result in an offering with  aggregate  gross  proceeds to Teijin in excess of
$7,500,000,  or such lesser  percentage if it  constitutes  all shares of voting
stock  held by  Teijin  at such  time) to be  registered  as soon as  reasonably
practicable so as to permit the sale thereof and in connection therewith prepare
and file,  on such  appropriate  form as the  Company  in its  discretion  shall
determine,  a  registration  statement  under the  Securities Act to effect such
registration  and seek to have such  registration  statement become effective as
promptly as practicable; provided, however, that each such request shall:

               (i)  specify  the number of  Registrable  Shares  intended  to be
offered and sold,

               (ii)  express the present  intention  of Teijin to offer or cause
the offering of such Registrable Shares for distribution,

               (iii)  describe  the nature or method of the  proposed  offer and
sale thereof, and

               (iv)  contain  the  undertaking  of  Teijin to  provide  all such
information  and  materials and take all such action as may be required in order
to permit the Company to comply with all applicable  requirements of the SEC and
to obtain any desired  acceleration  of the effective date of such  registration
statement.

         (b) Upon any registration  becoming  effective pursuant to this Section
1.1, the Company shall use its best efforts to keep such registration  statement
current for a period of 90 days.  Notwithstanding the foregoing, (i) the Company
shall not be obligated to cause any special audit to be undertaken in connection
with any such registration, (ii) the Company shall be entitled to postpone for a
reasonable period of time, but not in excess of 120 calendar days, the filing of
any registration  statement otherwise required to be prepared and filed by it if
the  Company at the time it  receives  a request  for  registration,  reasonably
believes in good faith,  and  discloses  to Teijin the reasons for such  belief,
that it would be disadvantageous to




<PAGE>


the Company for such filing to be made at the time  requested by Teijin in which
event the  Company  may  delay  the  preparation  and  filing of a  registration
statement  for a period  of up to 120 days and (iii)  the  Company  shall not be
obligated to file a registration  statement  pursuant to this Section 1.1 during
the 90-day period  following the  effectiveness  of any  registration  statement
filed by the Company in connection with an underwritten  primary offering of its
securities.  The obligation of the Company to register any Registrable Shares on
demand  by Teijin  in  accordance  with this  Section  1.1  shall  expire  after
registration statements filed by reason of such demands have become effective on
four  separate  occasions,  and in no event shall  Teijin be entitled to request
more than two demand registration  statements  hereunder in any 12-month period.
The Company  shall not be  obligated to file any  registration  statement if the
number of shares of Common  Stock to be  registered  for sale  would  exceed ten
percent  (10%) of the  aggregate  shares of Common  Stock then  outstanding.  In
connection  with any  demand  offering  under  this  section  1.1  involving  an
underwriting of shares of the Company's  capital stock, the Company shall select
the underwriters subject to the reasonable consent of Teijin.

     1.2 The Company's Obligations.  As to each offering of Common Stock covered
by a registration statement referred to in Section 1.1, the Company shall:

         (a) Use its best effort to have such  registration  statement  declared
effective as promptly as reasonably  practicable  on or after such time and date
as specified by Teijin and will promptly notify Teijin and its underwriters,  if
any, and confirm such advice in writing (i) when such registration statement has
become  effective,   (ii)  when  any   post-effective   amendment  to  any  such
registration statement becomes effective and (iii) of any request by the SEC for
any  amendment or supplement to such  registration  statement or any  prospectus
relating thereto or for additional information;

         (b) Furnish to Teijin or the underwriters  such number of copies of any
prospectus  (including  any  preliminary  prospectus)  in  conformity  with  the
requirements of the Securities Act, as Teijin may reasonably request in order to
effect the  offering  and sale of the shares of Common  Stock being  offered and
sold by Teijin,  but only while the  Company is  required  under the  provisions
hereof to cause the registration statement to remain current;

         (c) Use the best  efforts to  register  or  qualify  not later than the
effective date of such registration statement the shares of Common Stock held by
Teijin registered  thereunder under the "blue sky" laws of such states as Teijin
may  reasonably  request;  provided,  however,  that the  Company  shall  not be
obligated to qualify as a foreign corporation or as a dealer in securities or to
execute or file any general  consent to service of process under the laws of any
such state where it is not at such time so qualified or subject; and

         (d) For a period  of at least 90 days  from the  effective  date of the
registration  statement,  keep such registration statement in effect and current
and from time to time amend or  supplement  the  registration  statement and the
prospectus in connection therewith in compliance with the Securities Act and the
rules and regulations  adopted  thereunder to permit the sale or distribution of
the shares with respect to which such  registration  statement shall have become
effective.  If at any time the SEC should institute or threaten to institute any
proceedings

                                       2




<PAGE>


for the  purpose  of  issuing,  or  should  issue a stop  order  suspending  the
effectiveness  of any such  registration  statement,  the Company will  promptly
notify  Teijin and will use its best efforts to prevent the issuance of any such
stop order or to obtain the withdrawal thereof as soon as possible.  The Company
will advise Teijin promptly of any order or communication of any public board or
body  addressed  to  the  Company  suspending  or  threatening  to  suspend  the
qualification of any of the shares of Common Stock for sale in any Jurisdiction.

     1.3 Expenses.  The out-of-pocket  costs and expenses incurred in connection
with any registration pursuant to Section 1.1 shall be borne by Teijin, provided
that Teijin shall not be required to reimburse the Company for  compensation  of
the  Company's  officers  and  employees,  regular  audit  expenses,  and normal
corporate costs. The costs and expenses of any such registration  shall include,
without  limitation,  the reasonable fees and expenses of the Company's  counsel
and its  accountants  and all  other  out-of-pocket  costs and  expenses  of the
Company  incident to the  preparation,  printing and filing under the Securities
Act of the registration statement and all amendments and supplements thereto and
the  cost of  furnishing  copies  of each  preliminary  prospectus,  each  final
prospectus and, each amendment or supplement  thereto to  underwriters,  dealers
and other  purchasers of the  securities so  registered,  the costs and expenses
incurred in connection with the  qualification  of such securities so registered
under the "blue sky" laws of various jurisdictions, the fees and expenses of the
Company's  transfer agent and all other costs and expenses of complying with the
foregoing provisions of this Article I.

     1.4 Indemnification.

         (a) In the case of any offering registered pursuant to Section 1.1, the
Company hereby  indemnifies and agrees to hold harmless Teijin,  any underwriter
(as defined in the Securities Act) of shares offered by Teijin, and each person,
if any,  who  controls  Teijin or any such  underwriter  within  the  meaning of
Section  15 of the  Securities  Act  against  any  losses,  claims,  damages  or
liabilities,  joint or several, to which any such persons may be subject,  under
the  Securities  Act or otherwise,  and to reimburse any of such persons for any
legal  or  other  expenses  reasonably  incurred  by  them  in  connection  with
investigating  any claims or  defending  against  any  actions,  insofar as such
losses, claims, damages or liabilities arise out of or are based upon any untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in the
registration statement under which such Registrable Shares were registered under
the Securities Act pursuant to this Article I, any prospectus contained therein,
if used during the period  appropriate for such prospectus,  or any amendment or
supplement  thereto, or the omission or alleged omission to state therein (if so
used) a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances in which they were made, not
misleading,  except insofar as such losses, claims, damages or liabilities arise
out of or are (x) based upon any such  untrue  statement  or omission or alleged
untrue statement or omission made in reliance upon information  furnished to the
Company in writing by Teijin or any underwriter for Teijin  specifically for use
therein, or (y) made in any preliminary prospectus, and the prospectus contained
in the registration statement, as declared effective or in the form filed by the
Company  with the SEC pursuant to Rule 424 under the  Securities  Act shall have
corrected  such  statement or omission and a copy of such  prospectus  shall not
have  been  sent or  otherwise  delivered  to such  person  at or  prior  to the
confirmation of such sale to such person.

     1.5   Participation.   The   Company   will   permit   counsel   and  other
representatives  of Teijin to  participate  in meetings in  connection  with the
preparation of each  registration  statement  referred to in Section 1.1. Before
filing the  registration  statement or amendments or  supplements  thereto,  the

     (c) Business Day. If any payment  hereunder to the Bank shall fall due on a
day that is not a Business Day, then such due date shall be extended to the next
succeeding  Business Day, and such extension  shall be taken into account in the

     (a) shall subject the Bank to any tax, duty or other change with respect to
the Loan or shall  change the basis of  taxation  of payments to the Bank of the
principal  of, or  interest  on,  the Loan or any other  amounts  due under this
Agreement or the Note in respect of such Loan (except for changes in the rate of
taxation on the overall net income of the Bank imposed by the jurisdiction which
the Bank is located); or

     (b) shall impose,  modify or deem  applicable  any reserve  (including  any
imposed  by the Board of  governors  of the  Federal  Reserve  System),  special
deposit or similar  requirement  against  assets  of,  deposits  with or for the

such additional  amount or amounts as will reimburse the Bank for such increased

connection  with any payment or prepayment  (including any prepayment or payment
resulting from  acceleration) in respect of the Note or any portion thereof made
on a date other than the last day of the then current Interest Period. Such loss
may include the difference,  as reasonably  determined by the Bank,  between (i)

less  Applicable  Spread  that  would have  accrued  on the  portion of the Loan
repaid,  or (b) in the  case  of any  required  repayment,  the  Bank's  cost of
obtaining funds in an amount equal to the sum being repaid or prepaid,  and (ii)
any lesser amount which would have been realized by the Bank in reemploying  the
funds so received in  repayment or  prepayment  by placing such funds on deposit
for a comparable  period in the relevant market,  in each case during the period
from the date of repayment or prepayment  (as the case may be) to the end of the
then  current  Interest  Period.  The  certificate  of the Bank with  respect to
reimbursement  under this  Section  3.02 as to the  amount of any loss,  cost or
expense  incurred or to be  incurred by it shall show the amount  payable and in
reasonable  detail the calculations  used to determine in good faith such amount
and shall be conclusive  absent  manifest  error.  The Bank hereby agrees to use
reasonable commercial efforts to minimize any losses, costs or expenses incurred
or expended  for which the Bank seeks  reimbursement  pursuant  to this  Section
3.02.  The  Company  hereby  agrees  that  following  an Event of Default by the
Company  hereunder and the acceleration of the maturity of the Loan by the Bank,
a tender of payment of the amount  necessary to satisfy the entire  indebtedness
of the Loan  made at any time by the  Company  or by  anyone  on  behalf  of the
Company shall be deemed a voluntary prepayment hereunder.

                      REIMBURSEMENT AND SECURITY AGREEMENT

     This  REIMBURSEMENT AND SECURITY  AGREEMENT,  dated as of May 6, 1997 (this
"Agreement"),  is made by SOUTHWALL  TECHNOLOGIES,  INC., a Delaware corporation
(the "Grantor"),  and TEIJIN LIMITED, a Japanese  corporation,  as secured party
(the "Secured Party").

     PRELIMINARY STATEMENTS:

     (1) The Secured  Party has entered  into that certain  Guarantee  Agreement
Regarding  10 Million US$ Credit  Facility,  dated as of the date  hereof  (said
agreement,  as it may  hereafter be amended or otherwise  modified  from time to
time,  the "Guaranty  Agreement";  the terms  defined  therein and not otherwise
defined  herein are used  herein as therein  defined),  under  which the Secured
Party has agreed to provide  LENDER with a letter of  guarantee  (the "Letter of
Guarantee") as an inducement to extend a LOAN to the Grantor.

     (2) It is a  condition  precedent  to the  making of the  guarantee  by the
Secured Party under the Guaranty Agreement that the Grantor shall have agreed to
the reimbursement and security interest contemplated by this Agreement.

     NOW, THEREFORE, in consideration of the premises and in order to induce the
Secured Party to make the guarantee  under the Guaranty  Agreement,  the Grantor
hereby agrees with the Secured Party as follows.

     SECTION 1. Reimbursement; Assignment and Grant of Security Interest.

     (a) The Grantor  hereby agrees to reimburse the Secured Party on demand for
and in the amount of any payment  made by the Secured  Party to LENDER under the
Letter of Guarantee. All payments made by the Grantor under this Agreement shall
be made by the Grantor free and clear of and without  deduction  for any and all
present  and  future  taxes,  levies,  charges,   deductions  and  withholdings,
excluding,  in the case of the Secured Party, any of the foregoing imposed on or
measured  by its net  income  or  gross  receipts  by the  jurisdiction  (or any
political  subdivision  thereof)  under the laws of which the  Secured  Party is
organized or maintains a lending office ("Taxes").  To the extent applicable law
requires a deduction  or  withholding  for Taxes,  then the gross amount of such
payment made by the Grantor  shall be increased at the  Grantor's  sole cost and
expense such that the net payment to the Secured  Party or its  assignee  equals
that amount which the Secured Party or its assignee  would have received if such
deduction or withholding were not made. In addition,  the Grantor shall pay upon
demand any stamp or other  taxes,  levies or charges  of any  jurisdiction  with
respect to the execution, delivery, registration, performance and enforcement of
this Agreement.


<PAGE>

Upon  request  by  the  Secured  Party,   the  Grantor  shall  furnish  evidence
satisfactory  to  the  Secured  Party  that  all  requisite  authorizations  and
approvals  by, and notices to and filings  with,  governmental  authorities  and
regulatory  bodies have been  obtained  and made and that all  requisite  taxes,
levies and charges  have been paid.  Any  amounts  payable by the Grantor to the
Secured  Party  hereunder  not paid upon demand shall bear interest at an annual
rate equal to the six (6) months  LIBOR rate  established  by BBA at the time of
non-payment plus five percent (5%).

     (b) The Grantor  hereby  assigns to the Secured Party for its benefit,  and
hereby grants to the Secured  Party for its benefit a security  interest in, all
of the  Grantor's  right,  title and interest in and to  Grantor's  property set
forth on Exhibit A attached hereto (the  "Collateral"),  and all proceeds of any
and all of the foregoing Collateral.  The list of Collateral may be amended from
time to time by mutual  agreement of the parties;  provided,  however,  that the
Secured  Party shall have no obligation to agree to the amendment of the list of
Collateral if it believes that such amendment would impair the security interest
in the Grantor's property created hereunder.

     SECTION 2. Security for Obligations.  This Agreement secures the payment of
all  obligations  of the Grantor now or  hereafter  existing  under the Guaranty
Agreement   and  under  this   Agreement   (all  such   obligations   being  the
"Obligations").

     SECTION  3.   Representations,   Warranties  and  Covenants.   The  Grantor
represents and warrants as follows.

     (a) The Grantor is a corporation  duly organized,  validly  existing and in
good  standing  under the laws of the State of  Delaware;  the  Grantor  has the
lawful power to own its  properties and to engage in the businesses it conducts,
and is duly  qualified  and in good  standing  as a foreign  corporation  in the
jurisdictions  wherein the failure to so qualify  would have a material  adverse
effect on the Grantor or its business or prospects.

     (b) The  Grantor is not in  default  with  respect  to any of its  existing
indebtedness,  and the  making  and  performance  of  this  Agreement  will  not
(immediately or with the passage of time, the giving of notice, or both):

          (i)  violate  the   articles  of   incorporation,   by-laws  or  other
organizational  of the Grantor or violate any laws or result in a default  under
any  contract,  agreement,  or  instrument to which the Grantor is a party or by
which the Grantor or any of its property is bound; or

          (ii) result in the creation or imposition of any security interest in,
or lien or  encumbrance  upon,  any of the assets of the Grantor,  other than in
favor of the Secured Party.

                                       2

<PAGE>

     (c) The Grantor has the power and  authority to enter into and perform this
Agreement and to incur the  obligations  herein  provided for, and has taken all
actions necessary to authorize the execution,  delivery, and performance of this
Agreement.

its terms.

     (e) The chief place of business and chief  executive  office of the Grantor
and the office where the Grantor keeps its records  concerning  the  Collateral,
are located at 1029 Corporation Way, Palo Alto, California 94303.

     (f) The Grantor is, or as soon as  practicable  following  the Closing will
be, the legal and beneficial owner of the Collateral free and clear of any lien,
security interest, option or other charge or encumbrance except for the security
interest created by this Agreement and Permitted  Liens. No effective  financing
statement or other  document  similar in effect  covering all or any part of the
Collateral  is on file in any  recording  office,  except  such as may have been
filed in favor of the Secured  Party  relating to this  Agreement  and Permitted
Liens.  As used  herein,  "Permitted  Liens"  means (i)  liens to secure  taxes,
assessments  or charges not yet due or which are being  contested  in good faith
and by appropriate  proceedings and for which adequate  reserves are maintained;
(ii) carriers',  mechanics',  warehousemen's  artisans',  repairmen's or similar
liens arising in the ordinary  course of business which are not overdue or which
are being  contested in good faith and by appropriate  proceedings and for which
adequate  reserves are maintained;  and (iii) liens and  encumbrances  which (A)
existed on property  acquired by the Grantor before the time of its  acquisition
and was not created in anticipation of such event, or (B) were taken or retained
by the  seller of such  property  to secure  all or part of its price or created
solely for the purpose of  securing  indebtedness  representing,  or incurred to
finance or refinance the cost of such property; provided that no such Lien shall
extend to or cover any  property  of the  Grantor  other  than the  property  so
acquired and improvements on such property.

     (g) This Agreement  creates a valid and perfected  first priority  security
interest in the  Collateral  (other than with respect to  Permitted  Liens given
priority as a matter of law),  securing the payment of the Obligations,  and all
filings and other  actions  necessary  or  desirable to perfect and protect such
security interest have been duly taken.

     (h) No consent of any other person or entity and no authorization, approval
or other action by, and no notice to or filing with, any governmental  authority
or  regulatory  body is  required  (i)  for  the  grant  by the  Grantor  of the
assignment and security  interest granted hereby or for the execution,  delivery
or  performance  of this  Agreement by the Grantor,  (ii) for the  perfection or
maintenance of the assignment and security  interest  created hereby  (including
the first priority  nature of such  assignment  and security  interest) or (iii)
except as required by  applicable  law, for the exercise by the Secured Party of
its rights and remedies hereunder.

          SECTION 4. Further Assurances.

          (a) The Grantor  agrees that from time to time,  at the expense of the
Grantor,  the Grantor will promptly execute and deliver all further  instruments
and documents,  and take all further action, that may be necessary or desirable,
or that the  Secured  Party may  reasonably  request,  in order to  perfect  and
protect the assignment and security  interest granted or purported to be granted
hereby or to enable the  Secured  Party to  exercise  and enforce its rights and
remedies  hereunder  with  respect  to  any  Collateral.  Without  limiting  the
generality of the foregoing,  the Grantor will: (i) if any  Collateral  shall be
evidenced by a promissory  note or other  instrument or chattel paper,  promptly
notify the Secured Party  thereof and, if  requested,  deliver and pledge to the
Secured Party  hereunder  such note or instrument or chattel paper duly endorsed
and accompanied by duly executed  instruments of transfer or assignment,  all in
form and substance  reasonably  satisfactory to the Secured Party;  (ii) execute
and file such financing or continuation  statements,  or amendments thereto, and
such other instruments or notices,  as may be necessary or desirable,  or as the
Secured Party may

                                       5


<PAGE>

reasonably request, in order to perfect and preserve the assignment and security
interest granted or purported to be granted hereby; and (iii) mark conspicuously
any  Collateral  and, at the request of the Secured  Party,  each of its records
pertaining to the  Collateral  with a legend,  in form and substance  reasonably
satisfactory to the Secured Party, indicating that such Collateral is subject to
the assignment and security interest granted pursuant hereto.

          (b) The Grantor  hereby  authorizes  the Secured  Party to file one or
more financing or continuation statements,  and amendments thereto,  relating to
all or any part of the  Collateral  without the  signature of the Grantor  where
permitted by law. A photocopy  or other  reproduction  of this  Agreement or any
financing  statement  covering  the  Collateral  or any party  thereof  shall be
sufficient as a financing statement where permitted by law.

          (c)  During  the  term  of the  LOAN,  as  specified  in the  Guaranty
Agreement,  the amount of  Grantor's  inventory,  consisting  of raw  materials,
work-in-process and finished goods  ("Inventory"),  that shall constitute a part
of the Collateral will at all times be an amount equal to the difference between
120% of the principal and accrued interest then owing under the LOAN and the net
value  (defined  as the  purchase  price  for  the  equipment  less  accumulated
depreciation  calculated  at the rate of 10% per  annum)  of the  equipment  and
machinery that  constitutes a part of the  Collateral.  The Secured Party agrees
that its security  interest in Inventory shall be limited to Inventory  having a
value  equal to the amount  described  in the  preceding  sentence.  The Grantor
acknowledges  that, upon the occurrence of a Default,  the Secured Party intends
to look to the  components of the Inventory in the following  order of priority:
finished goods, work-in-process and raw materials.

          (d) The Secured Party agrees to execute such  agreements and documents
that may be  reasonably  necessary  to confirm the scope of its  interest in the
Inventory upon the reasonable request of Grantor.

          SECTION 5. Place of  Perfection;  Records.  The Grantor shall keep its
chief place of business  and chief  executive  offices and the offices  where it
keeps its records  concerning  the  Collateral,  and the original  copies of all
chattel paper or other documents or instruments  that evidence the Collateral at
the locations therefor specified in Section 3(e) or, upon 30 days' prior written
notice to the Secured Party, at any other locations in a jurisdiction  where all
action  required  by  Section  4 shall  have  been  taken  with  respect  to the
Collateral.  The Grantor will hold and preserve such  records,  and such chattel
paper,  documents and instruments and will permit representatives of the Secured
Party at any time during normal  business  hours and upon  reasonable  notice to
inspect and make  abstracts  from such  records,  chattel  paper,  documents and
instruments.

          SECTION 6. As to the Collateral.

          (a) The Grantor shall at its expense:

                                       6

<PAGE>

               (i) properly  maintain the Collateral and take all such action to
such end as may be from time to time reasonably  requested by the Secured Party;
and

              (ii) furnish to the Secured Party  promptly  upon receipt  thereof
copies of all  notices,  requests  and other  documents  received by the Grantor
relating  to the  Collateral,  and from time to time (A)  furnish to the Secured
Party such information and reports regarding the Collateral as the Secured Party
may  reasonably  request and (B) upon  request of the Secured  Party make to any
other party such demands and requests for  information and reports or for action
as the Grantor is entitled to make, respecting the Collateral.

          (b) The Grantor shall not:

               (i) sell,  assign (by operation of law or otherwise) or otherwise
dispose of, or grant any option with  respect to, any of the  Collateral  (other
than a proposed sale or other disposition of obsolete or worn-out equipment,  in
which events Grantor shall provide  Secured Party with thirty (30) days advanced
written  notice),  or create or  permit  to exist any lien,  security  interest,
option  or  other  charge  or  encumbrance  upon or with  respect  to any of the
Collateral,  except  for the  assignment  and  security  interest  under by this
Agreement or Permitted Liens; or

               (ii) take any  other  action in  connection  with the  Collateral
which would  impair the value  thereof or the  interest or rights of the Grantor
therein  or which  would  impair the  interest  or rights of the  Secured  Party
therein.

hereby  appoints the Secured  Party the  Grantor's  attorney-in-fact,  with full
authority  in the place and stead of the  Grantor and in the name of the Grantor
or  otherwise,  from time to time,  after the  Secured  Party has  notified  the
Grantor of a Default  under this  Agreement  and for so long as any such Default
exists, in the Secured Party's  discretion to take any action and to execute any
instrument which the Secured Party may deem necessary or advisable to accomplish
the purposes of this Agreement, including, without limitation:

               (i) to  ask,  demand,  collect,  sue  for,  recover,  compromise,
receive and give  acquitance and receipts for moneys due and to become due under
or in connection with the Collateral;

               (ii)  to  receive,  endorse  and  collect  any  drafts  or  other
instruments, documents and chattel paper in connection therewith; and

              (iii) to file any  claims  or take any  action  or  institute  any

expenses of the Secured Party incurred in connection  therewith shall be payable
by the Grantor under Section 11(b).

          SECTION 9. The Secured  Party's  Duties.  The powers  conferred on the
Secured Party hereunder are solely to protect its interest in the Collateral and
shall not impose any duty upon it to exercise  any such  powers.  Except for the
safe custody of any  Collateral in its  possession and the accounting for moneys
actually  received by it  hereunder,  the Secured Party shall have no duty as to
any  Collateral  or as to the taking of any necessary  steps to preserve  rights
against  any  parties or any other  rights  pertaining  to any  Collateral.  The
Secured Party shall be deemed to have exercised  reasonable  care in the custody
and  preservation  of any  Collateral in its  possession  if such  Collateral is
accorded treatment  substantially  equal to that which the Secured Party accords
its own property.

          SECTION  10.  Remedies.  If after  five (5) days'  written  notice the
Grantor  fails to  reimburse  or pay any amounts due to the Secured  Party under
Section 1(a) of this  Agreement,  or if the Grantor  fails to observe or perform
any other  material term of this  Agreement  which  continues  unremedied  for a
period of thirty (30) days after written notice thereof (each a "Default"):

          (a) The  Secured  Party may  exercise  any and all legal or  equitable
rights  and  remedies  of the  Grantor in  connection  with or in respect of the
Collateral in any court or other  tribunal of proper  jurisdiction;  the Grantor
and the Secured  Party  acknowledge  and agree that the  remedies of the Secured
Party under this  Agreement are not subject to the  arbitration  provisions  set
forth in Section 8.2 of the Guaranty Agreement;

          (b) All payments  received by the Grantor in  connection or in respect
of the  Collateral  shall be  received  in trust for the  benefit of the Secured
Party,  shall be  segregated  from  other  funds  of the  Grantor  and  shall be
forthwith  paid over to the Secured Party in the same form as so received  (with
any necessary endorsement);

          (c) All payments made under or in connection with or in respect of the
Collateral, and all cash proceeds in respect of any sale of, collection from, or
other  realization  upon  all or any  part of the  Collateral,  received  by the
Secured  Party may,  in the  discretion  of the  Secured  Party,  be held by the
Secured Party as collateral for,  and/or then or at any time thereafter  applied
(after  payment of any amounts  payable to the Secured Party pursuant to Section
11) in whole or in part by the  Secured  Party  against,  all or any part of the
Obligations in such order as the Secured Party shall elect.  Any surplus of such
payments or cash proceeds held by the Secured Party and remaining  after payment
in  full  of all the  Obligations  shall  be  paid  over  to the  Grantor  or to
whomsoever may be lawfully entitled to receive such surplus; and

          (d) The Secured  Party may exercise in respect of the  Collateral,  in
addition to other rights and remedies provided for herein or otherwise available
to it, all the  rights  and  remedies  of a secured  party on default  under the
Uniform Commercial Code in

                                       8

any and all claims,  losses and  liabilities  (including  reasonable  attorneys'
fees)  growing  out of or  resulting  from this  Agreement  (including,  without
limitation, enforcement of this Agreement), except claims, losses or liabilities
resulting from the Secured Party's gross negligence or willful misconduct.

          (b) The Grantor  will upon demand pay to the Secured  Party the amount

and  expenses of its  counsel  and of any experts and agents,  which the Secured
Party may incur in connection  with (i) the  administration  of this  Agreement,

realization  upon, any of the  Collateral,  (iii) the exercise or enforcement of
any of the rights of the  Secured  Party  hereunder  or (iv) the  failure by the

Secured Party will, at the Grantor's expense, execute and deliver to the Grantor
such  documents  as the  Grantor  shall  reasonably  request  to  evidence  such
termination.

          SECTION 15. Governing Law; Terms.  This Agreement shall be governed by
and construed in accordance with the laws of the State of California,  except to

Collateral  are governed by the laws of a  jurisdiction  other than the State of
California.  Unless  otherwise  defined herein,  terms used in Division 9 of the
Uniform  Commercial Code in effect in the State of California are used herein as
therein defined.

          SECTION 16.  Waiver of Jury Trial.  THE GRANTOR AND SECURED PARTY BOTH
HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVES ANY RIGHTS THEY MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
