2.   NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE

     Net income per share amounts are computed using the weighted average number
of common  and common equivalent shares.  For the three and six months ended
June 30, 1996, common equivalent shares consisted of stock options and warrants
(using the treasury stock method). For the three and six months ended June 30,
1995, common equivalent shares consisted of convertible preferred stock (using
the if converted method) and stock options and warrants (using the modified
treasury stock method).

3.   SHORT-TERM INVESTMENTS

     Short-term investments consist of U. S. government debt securities
(carrying value of $956,206 at June 30, 1996), state and municipal debt
securities (carrying value of $1,032,000 at at June 30, 1996) and corporate debt
securities (carrying value of $7,715,448 at June 30, 1996).  At June 30, 1996,
all of these securities were classified as available for sale.  Accordingly,
these securities are stated at fair value, with unrealized gains and losses
reported as a separate component of stockholders' equity.  Interest on all
securities is included in interest income.

     The Company's Board of Directors has approved investment guidelines with
regard to diversification, quality, maturities and allowed investments.  At the
time of purchase there can be no more than 10% of the portfolio invested per
issuer or guarantor with the exception of U. S. government backed securities,

5.   COMMITMENTS

     In May 1996, the Company entered into an  Option Agreement with Taiwan
Semiconductor Manufacturing Co., Ltd. ("TSMC") (the "Option Agreement").
Pursuant to the Option Agreement, the Company agreed to pay $5,880,000 as an
advance payment for certain quantities of wafers, of which $2,500,000 was paid
in May 1996 and the Company issued a promissory note due March 31, 1997 for the
remaining $3,380,000.  Under the terms of the Option Agreement, which is
essentially a take or pay arrangement, the Company has committed to purchase
from TSMC and TSMC has committed to provide to the Company  certain quantities
of wafers through 2000.  Additionally, in July 1996, the Company entered into a
Wafer Production Agreement (the "Wafer Agreement") with TSMC which primarily
governs the production and supply process relating to the wafers to be purchased
under the Option Agreement.

6.   COMMON STOCK

     In December 1995, the Company sold 1,000,000 shares of its common
stock pursuant to an initial public offering ("IPO").  In January 1996, the
underwriters of the Company's IPO purchased an additional 85,000 shares of the
Company's common stock to cover over-allotments on the same terms and conditions
as set forth in the prospectus for the IPO dated December 1, 1995.  The Company
received net proceeds of $584,384 from the sale of the additional shares.

7.   CONTINGENCY

     In December 1995, the Company filed a lawsuit against Dallas Semiconductor
Corporation in the United States District Court for the Eastern District of
Texas, Sherman Division (the "Court"). In the lawsuit, the Company was seeking
a declaratory judgment of non-infringement of eight United States patents issued
to Dallas Semiconductor. The lawsuit was filed by the Company in response to
Dallas Semiconductor's allegation of patent infringement. In June 1996, the
Court dismissed the lawsuit against Dallas Semiconductor for lack of subject
matter jurisdiction. Because the Court ruled it did not have jurisdiction over
the matter, no decision as to the merits of the case was reached.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
            OF OPERATIONS



OVERVIEW

     BENCHMARQ was incorporated in 1989 and is engaged in the design,
development and marketing of mixed-signal integrated circuits ("ICs") and
electronic modules for portable and power-sensitive electronic systems.  The
Company introduced its first products in October 1990, and made its first
shipments, principally of nonvolatile static random access memory ("NVSRAM")
modules, in December 1990.  In August 1991, the Company shipped its initial
battery management product and in December 1991 shipped its first real-time-
clock ("RTC") product.

     BENCHMARQ currently is directing the majority of its research and
development efforts to the development of battery management products.  The
Company believes that its revenues from RTC products and NVSRAM products will
not increase materially in the future and may decline due to competitive
pressure or continued softness in demand from customers in the desk- top
personal computer ("PC") and networking markets, respectively.  Accordingly, the
Company expects that favorable future operating results will be substantially
dependent upon its ability to expand sales of battery management products.  The
Company has experienced significant growth in sales of battery management
products in the last three quarters primarily due to increased sales of battery
capacity monitoring devices (gas gauge ICs) into portable PC applications.
Consequently, the Company is in the process of adding test capacity principally
to address increased demand for gas gauge ICs.  The Company's objective is to
continue to grow battery management revenues, which have been the Company's
largest revenue product line for the last three consecutive quarters, to a more
dominant position within the Company's revenue structure.  There can be no
assurance that the Company will be successful in substantially increasing sales
of battery management products or that sales of RTC products or NVSRAM products
will not decline.



RESULTS OF OPERATIONS

Three Months Ended June 30, 1996, Compared with Three Months Ended June 30, 1995

     Net Revenues.  Total net revenues in second quarter 1996 were approximately
$9.1 million, a 27% increase over the same period in 1995.  Revenues generated
by product sales accounted for $9.0 million of total net revenues in second
quarter 1996, an increase of 34% compared to the same period in 1995.  This
increase was due principally to increased sales of gas gauge ICs into the
portable PC market, and to a lesser extent sales of higher density NVSRAM
modules, which are sold into telecom and networking markets.

                                       10
<PAGE>
 
     Revenue generated from RTC royalties and other miscellaneous sources was
0.9% of total revenue in second quarter 1996, compared with 6.4% in second
quarter 1995.  This reduction, which reflects a materially lower dependence on
these non-strategic activities, is due principally to the fourth quarter 1995
termination of a third party  design contract and significantly lower third
party shipments of products that incorporate the Company's RTC technology under
license agreement.

     The following table sets forth for the periods indicated the amount (in
thousands) and percentage of total net revenues by type of product:

</TABLE>

     The Company's revenues from international customers accounted for
approximately $5.8 million, or 64% of total net revenues, for the quarter ended
June 30, 1996, compared to $3.7 million, or 51% of total net revenues, for the
comparable period in 1995.  During the second quarter of 1996, approximately 58%
of the Company's total net revenues was derived from customers in the Asia-
Pacific region. The Company's distributor in Taiwan accounted for approximately
$1.6 million, or 18%, of total net revenues in the second quarter of 1996.  The
Company's distributor in South Korea accounted for approximately $1.0 million,
or 11%, of total net revenues in the second quarter of 1996.  No other customer
directly accounted for greater than 10% of the total net revenues.

     Export sales are subject to a variety of risks, including those
arising from fluctuations in currency exchange rates, tariffs, import
restrictions and other trade barriers, unexpected changes in regulatory
requirements, longer accounts receivable payment cycles, potentially adverse tax
consequences and export license requirements.  Because the Company's
international sales have to date been denominated in U.S. dollars, increases in
the value of the U.S. dollar could increase the price in local currencies of the
Company's products in foreign markets and make the Company's products relatively
more expensive than competitors' products that are denominated in local
currencies.

     Gross Margin.  The Company's gross margin represented 44% of total net
revenues for both three month periods ended June 30, 1996 and 1995.  Gross
Margin increased approximately $833,000, or 26%, to approximately $4.0 million
for the second quarter 1996, compared to $3.2 million in the second quarter
1995. Excluding the impact of royalties and design fees, the gross margin
percentage would have been approximately 43% and 40%  in the second quarter 1996
and 1995, respectively.

                                       11
<PAGE>
 
     The Company expects that average selling prices, primarily with respect to
its RTC and NVSRAM products will continue to decline. To maintain or increase
its gross margin and gross margin percentage, the Company believes that it will
be required to increase its sales of battery management products, achieve lower
wafer costs and continue its efforts to improve manufacturing costs.
Accordingly, the Company entered into the Option and Wafer Agreements with its
principal wafer supplier, pursuant to which it should (subject to certain
currency exchange related adjustments) achieve generally lower wafer costs for
the remainder of 1996 and in 1997 as compared to the first half of 1996. There
can be no assurance, however, that the Company will be able to achieve these
objectives.

     Research and Development.  The Company's research and development
expense increased approximately 24% to $700,000 in the second quarter 1996,
compared to $565,000 in second quarter 1995.  This increase was due primarily to
increased compensation and payroll related expenses.  As a percentage of total
revenues, research and development expense decreased to approximately 7.7% in
second quarter 1996 from 7.9% in second quarter 1995.

     The Company intends to continue to make a significant investment in
research and development, particularly with respect to battery management
product opportunities, and believes that research and development expense will
therefore increase in absolute dollars.

     Selling, General and Administrative.  Selling, general and
administrative expense increased approximately $559,000 to $2.0 million in
second quarter 1996 as compared to the same period in 1995.  This increase was
due primarily to increases in compensation, external sales commissions,
depreciation, legal, and other general expenses.  Although general legal
expenses were up, much of the increase in legal expenses was due to the
litigation proceedings against Dallas Semiconductor Corporation.  Selling,
general and administrative expense represented approximately 22.4% and 20.5% of
total net revenues in second quarter 1996 and 1995, respectively.  Selling,
general and administrative expense in absolute dollars is expected to continue
to increase as the Company expands its business.

     Other Income (Expense).  Other income (expense), consists primarily of
interest earned on short-term investments, net of interest expense on capital
lease obligations, and a $2.0 million subordinated note payable in 1995.  In
second quarter 1996, the Company realized net other income of approximately
$96,000, compared to $8,000 in second quarter 1995.  This improvement primarily
reflects higher average balances of invested funds and the retirement of the
$2.0 million subordinated note payable in December 1995.  Proceeds from the
Company's IPO contributed significantly to the increase in funds available for
investment.

     Provision for Income Taxes.  The Company generated pre-tax income
during the second quarter 1996 and 1995, which was substantially offset by net
operating loss carryforwards from prior operating periods.  Provisions for
income taxes of $98,800 and $87,800 were recorded in the three months ended June
30, 1996 and 1995, respectively, consisting of alternative minimum tax and state
income tax.

Six Months Ended June 30, 1996, Compared with Six Months Ended June 30, 1995

     Net Revenues.  Total net revenues for the six months ended June 30,
1996 were approximately $17.5 million, a 27% increase over the same period in
1995.  Revenues generated by product sales accounted for $17.3 million of total
net revenues for the six months ended June 30, 1996, an increase of 35% compared
to the same period in 1995.  This increase was due principally to increased
sales of gas gauge ICs into the portable PC market, and to a lesser extent sales
of higher density NVSRAM modules, which are sold into telecom and networking
markets.  Revenue generated from RTC royalties and other miscellaneous sources
was 1.3% of total revenue for the six months ended June 30, 1996, compared with
7.5% for the six months ended June 30, 1995.

     The Company's revenues from international customers accounted for
approximately $11.0 million, or 63% of total net revenues, for the six months
ended June 30, 1996, compared to $7.5 million, or 54% of total net revenues, for
the comparable period in 1995.  During the six months ended June 30, 1996,
approximately 56% of the Company's total net revenues was derived from customers
in the Asia-Pacific region. The Company's distributor in Taiwan accounted for
approximately $3.1 million, or 18%, of total net revenues for the six months
ended June 30, 1996. The Company's distributor in South Korea accounted for
approximately $1.8 million, or 10%, of total net revenues for the six months
ended June 30, 1996.  No other customer directly accounted for greater than 10%
of the total net revenues.


     Gross Margin.  The Company's gross margin represented 42% and 44% of
total net revenues for the six month periods ended June 30, 1996 and 1995,
respectively.  Gross Margin increased approximately $1.3 million, or 21%, to
approximately $7.4 million for the six month period ended June 30, 1996,
compared to $6.1 million for the six month period ended June 30, 1995.  The
decrease in gross margin percentage is attributable primarily to lower royalty
revenues and no design contract fees for the six months ended June 30, 1996.
Excluding the impact of royalties and design fees, the gross margin percentage
would have been approximately 42% and 40% for the six months ended June 30, 1996
and 1995, respectively.

                                       13

     Research and Development.  The Company's research and development
expense increased approximately 21% to $1.3 million for the six months ended
June 30, 1996 as compared to approximately $1.1 million for the six months ended
June 30, 1995.  This increase was due primarily to increased compensation and
payroll related expenses.  As a percentage of total revenues, research and
development expense decreased to approximately 7.4% for the six months ended
June 30, 1996 from 7.7% for the comparable period in 1995.

     Selling, General and Administrative.  Selling, general and
administrative expense increased approximately $948,000 to $3.8 million for the
six months ended June 30, 1996 as compared to the same period in 1995.  This
increase was due primarily to increases in compensation, external sales
commissions, depreciation, legal, and other general expenses. Although general
legal expenses were up, much of the increase in legal expenses was due to the
litigation proceedings against Dallas Semiconductor Corporation.  Selling,
general and administrative expense represented approximately 21.9% and 20.9% of
total net revenues for the six months ended June 30, 1996 and 1995,
respectively.

     Other Income (Expense).  Other income (expense), consists primarily of
interest earned on short-term investments, net of interest expense on capital
lease obligations, and a $2.0 million subordinated note payable in 1995.  For
the six months ended June 30, 1996, the Company realized net other income of
approximately $210,000, compared to $15,000 for the same period in 1995.  This
improvement primarily reflects higher average balances of invested funds and the
retirement of the $2.0 million subordinated note payable in December 1995.
Proceeds from the Company's IPO contributed significantly to the increase in
funds available for investment.

     Provision for Income Taxes.  The Company generated pre-tax income
during the six month periods ended June 30, 1996 and 1995, which was
substantially offset by net operating loss carryforwards from prior operating
periods.  Provisions for income taxes of $166,300 and $170,400 were recorded in
the six months ended June 30, 1996 and 1995, respectively, consisting of
alternative minimum tax and state income tax.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's principal capital needs are to finance accounts
receivable, inventories and additions of capital assets.  Approximately $2.5
million of cash was generated by operating activities during the six month
period ended June 30, 1996 as compared to $1.8 million in the comparable period
in 1995.

     Net cash used in investing activities of approximately $12.9 million
during the six month period ended June 30, 1996 was attributable primarily to
the investment of much of the Company's cash equivalents into short-term
investments to improve interest income.  In addition, approximately $2.5 million
was used for a prepayment for certain quantities of wafers pursuant to the
Option Agreement under which TSMC is committed to supply and the Company is
committed to purchase wafers.  Finally, approximately $697,000 was used for
capital expenditures consisting primarily of assembly and test capacity
expansion.  Net cash used in investing activities during the 

                                       14
<PAGE>
 
six month period ended June 30, 1995 amounted to approximately $492,000 and
consisted of capital expenditures.

     Financing activities have consisted primarily of the issuance of
equity and payments under capital lease obligations.  Financing activities used
cash during the six month period ended June 30, 1996 of approximately $4,000
consisting of proceeds of approximately $638,000 from issuances of stock and
payments of approximately $642,000 under capital lease obligations. During the
six month period ended June 30, 1995, financing activities used net cash of
approximately $389,000,  primarily due to payments under capital lease
obligations.

     The Company's principal sources of liquidity are cash generated from
operations as well as cash and cash equivalents and short-term investments of
approximately $11.9 million at June 30, 1996.  The Company's short-term
investments are primarily in government debt securities and corporate debt
securities. In addition, the Company has a lease line with BancBoston Leasing,
Inc., which was recently increased by $1.5 million.  During the six month period
ended June 30, 1996, the Company used approximately $1.6 million of credit under
its outstanding lease line primarily for additions of assembly and test
equipment.  As of July 31, 1996, approximately $1.5 million was available for
additional purchases.  However, as of such date, equipment  purchase orders
totaling approximately $280,000 were outstanding against the available lease
line of credit.

     The Company anticipates capital asset additions to range between $1.5
million and $2.5 million for the remainder of 1996, primarily to expand test
capacity for certain of its battery management products, a portion of which may
be financed under the Company's lease line.  To secure access to a supply of
wafers the Company entered into the Option and Wafer Agreements  with TSMC under
which TSMC is commited to supply and the Company is committed to purchase
wafers. Pursuant to the Option Agreement, the Company made a cash payment of
$2.5 million and issued a short-term note payable for $3.38 million (payable by
March 31, 1997) as prepayment of certain quantities of wafers.

     The Company believes that existing cash balances and other capital
resources will be sufficient to meet the Company's cash requirements at least
through 1996.  However, the Company may also seek to establish additional lines
of credit to augment its funding of operating activities during 1996.  There can
be no assurance that such additional financing, if required, will be available
on terms acceptable to the Company if at all.

     In addition, the Company may, from time to time, as market and
business conditions warrant, invest in or acquire complementary businesses,
products, technologies and additional sources of wafer supply.  The Company also
may seek additional equity or debt financing to fund such activities.  The sale
of additional equity or convertible debt securities could result in dilution to
the Company's stockholders.  There can be no assurance that such additional
financing, if required, will be available on terms acceptable to the Company, if
at all.

INFLATION

     The Company believes that inflation has not had and is not likely to
have a material impact on the Company's operations during the foreseeable
future.

SEASONALITY

     Certain of the Company's product revenues and related profits may be
subject to traditional semiconductor industry seasonality factors that may act
to soften sales demand in the three month period ending September 30.

PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

        In December 1995, the Company filed a lawsuit against Dallas
Semiconductor Corporation in the United States District Court for the Eastern
District of Texas, Sherman Division (the "Court").  In the lawsuit, the Company
was seeking a declaratory judgment of non-infringement of eight United States
patents issued to Dallas Semiconductor.  The lawsuit was filed by the Company in
response to Dallas Semiconductor's allegation of patent infringement. In June
1996, the Court dismissed the lawsuit against Dallas Semiconductor  for lack of
subject matter jurisdiction.  Because the Court ruled it did not have
jurisdiction over the matter, no decision as to the merits of the case was
reached.

12. GOVERNING LAW


      This Agreement will be governed by and interpreted in accordance with the
      laws of the California.


13. ARBITRATION


  (a) General.  Each party will make best efforts to resolve amicably any
      -------                                                            
      claims, controversies, or disputes under this Agreement. In the event that
      a resolution is not reached among the parties within thirty (30) days
      after written notice by any party of the dispute or claim, the dispute or
      claim shall be finally settled by binding arbitration in accordance with
      the provisions of this Section 13. The parties agree that all actions,
      claims, controversies or disputes of any kind (e.g. whether in contract or
      in tort, statutory or common law, legal or equitable or otherwise)
      ("Disputes") between them relating, directly or indirectly, to this
      Agreement are to be resolved by arbitration as provided in this Agreement.
      All arbitration will be 

                                       9
<PAGE>
 
      conducted pursuant to and in accordance with the following order of
      priority (i) the terms of this Agreement, (ii) the Commercial Arbitration
      Rules of the American Arbitration Association, and (iii) to the extend the
      foregoing are inapplicable, unenforceable or invalid, the laws of the
      State of California. The arbitrator(s) used will be selected from a list
      of persons familiar with disputes regarding the semiconductor
      manufacturing industry to be provided by the American Arbitration
      Association. Any hearing regarding arbitration will be held in the Greater
      Bay Area, California, or at another location mutually acceptable to both
      parties. The parties will use reasonable efforts to assure that the
      arbitrator(s) will use their best efforts to conduct the arbitration
      hearing as soon as practicable.

  (b) Discovery.  Discovery will be conducted solely through depositions and
      ---------                                                             
      requests for documents and things but otherwise will be governed by the
      Federal Rules of Civil Procedure. The arbitrator(s) will resolve any
      discovery disputes by such prehearing conferences as may be needed. Both
      parties agree that the arbitrator(s) will have the power of subpoena
      process as provided by law. Disputes concerning the scope of depositions
      or document production, its reasonableness and enforcement of discovery
      requests will be subject to Agreement by the parties or will be resolved
      by the arbitrator(s). All discovery requests will be subject to the
      proprietary rights and rights of privilege and other protections granted
      by applicable law to the parties. The arbitrator(s) will adopt procedure
      to protect such rights. With respect to any Dispute, each party agrees
      that all discovery activities shall be expressly limited to matters
      directly relevant to the Dispute and the arbitrator(s) will be required to
      fully enforce this requirement.

  (c) Enforcement.  The decision of the arbitrator(s) will be final and binding
      -----------                                                              
      on all parties. Any judgment upon the award rendered by the arbitrator(s)
      may be entered in any court having jurisdiction thereof. The decision of
      the arbitrator(s) will be enforceable in any court of competent
      jurisdiction. Except for proceedings seeking equitable remedies, an
      arbitration proceeding commenced pursuant to this Section 13 is a
      condition precedent to and is a complete defense to the commencement of
      any suit, action or proceeding in any federal or state court with respect
      to any Dispute. Either party may bring an action in court to compel
      arbitration. Any party who fails or refuses to submit to binding
      arbitration following demand by the other party shall bear all costs and
      expenses incurred by the opposing party in compelling arbitration.

                                       10

  (d) Powers and Qualifications: Awards: Modification or Vacation of Award.  The
      --------------------------------------------------------------------      
      arbitrator(s) are empowered to resolve Disputes by summary rulings
      substantially similar to summary judgments and motions to dismiss. The
      arbitrator(s) will resolve all Disputes in accordance with the substantive
      laws of the State of California. The arbitrator(s) may grant any remedy or
      relief deemed just and equitable and within the scope of this Agreement
      and may also grant such ancillary relief as is necessary to make effective
      any award. The arbitrator(s) will be required to make specific, written
      findings of fact and conclusions of law, and the parties will have the
      right to seek vacation or modification of an award only if (I) that award
      is based in whole, or in part, upon fraud or (ii) failure to follow the
      procedures set forth in this Section 13. For these purposes, the award and
      judgment entered by the federal or state district court shall be
      considered to be the same as the award and judgment of the arbitrator(s).
      To the extent permitted by applicable law, the arbitrator(s) will have the
      power to award recovery of all costs and fees (including attorneys' fees,
      administrative fees, and arbitrators' fees) to the prevailing party.

  (e) Limitation on Award.  The arbitrator(s) will be limited to interpreting
      -------------------                                                    
      the applicable provisions of this Agreement, and will not have the
      authority or power to alter, amend, modify, revoke or suspend any
      condition or provision of this Agreement, nor to create, draft or form a
      new agreement between the parties, nor to render an award which, by its
      terms, has the effect of altering or modifying any condition or provision
      of this Agreement.

  (f) Provisional Remedies and Multiple Parties.  No provision of, nor the
      -----------------------------------------                           
      exercise of any rights under, this Agreement will limit the right of any
      party, during any Dispute, to resort to a court of applicable jurisdiction
      to seek such equitable remedies as may be available to such party, and any
      such action will not be deemed an election of remedies. Such rights will
      include, without limitation, rights and remedies relating to injunctive
      relief. Such rights may be exercised at any time except to the extent such
      action is contrary to an award or decision of the arbitrator(s). The
      institution and maintenance of an action for equitable relief will not
      constitute a waiver of the right of any party, to submit a Dispute to
      arbitration, nor render inapplicable the compulsory arbitration provisions
      of this Agreement.

  (g) Choice of Arbitrator(s).  The arbitrator(s) will be chosen by mutual
      -----------------------                                             
      agreement of the parties. If they cannot agree within thirty (30) days
      upon a single arbitrator, each will, within fifteen (15) days

                                       11
<PAGE>
 
      thereafter, appoint an arbitrator and such arbitrators will appoint a
      third impartial arbitrator. If more than one arbitrator is appointed, the
      decision of a majority of such arbitrators will be binding. Subject to the
      provisions of Subsection 13(d), (i) each party will be responsible for the
      expenses and fees of the arbitrator appointed by it and one-half of the
      fees and expenses of the third arbitrator, (ii) if there is only one
      arbitrator appointed, each party will be responsible for one-half of the
      fees and expenses of such arbitrator and (iii) each party will bear its
      own attorney's and expert's fees. If either party fails to timely appoint
      an arbitrator, the decision of the arbitrator who is timely appointed will
      be binding.


14. ASSIGNMENT

      installation, device packaging or shipping package,
      repair or alteration by someone other than TSMC, or improper testing or
      use contrary to any instructions given by TSMC, then TSMC shall, at its
      option, either repair, if applicable, replace, or credit
      Customer for such defective Products XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
      XXXXXXXXXX.  TSMC shall return any Products repaired or replaced under
      this warranty to Customer transportation prepaid, and shall reimburse
      Customer for the transportation charges paid by Customer for returning
      such defective Products to TSMC.  The performance of this warranty shall

      originally delivered.

  (b) The foregoing constitutes TSMC's exclusive liability, and Customer
      exclusive remedy for any breach of warranty under this Agreement,

      XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
      XXXXXXX.  If TSMC thereby determines that the allegedly defective Products
      are defective or non-conforming with the Quality and Reliability
      Specifications, or that such alleged defects are caused by defects in
      material or workmanship of TSMC, then Customer shall be entitled to
      repair, replacement or credit under this Subsection.

10.   INTELLECTUAL PROPERTY INDEMNITY


  (a) Subject to Subsection 10(b) below, TSMC shall, at its expense and at
      Customer request, defend any claim or suit brought against Customer,

      answer the charge of infringement and defend such claim or suit;  (ii)
      Customer provides TSMC information, assistance and authority, at TSMC's
      expense, to enable TSMC to defend such suit or claim; and  (iii) TSMC
      shall not be responsible for any settlement made by Customer without TSMC
      written permission.

  (b) TSMC shall have no liability under this Agreement for any claim or suit
      where infringement arises solely out of TSMC's compliance with or
      implementation of any of Customer's instructions, specifications, designs
      or requirements (including those relating to the Process) hereunder, and
      Customer shall defend such claim or suit and indemnify and hold TSMC
      harmless from and against any costs, damages and fees reasonably incurred
      by TSMC in connection with such claim or suit, including but not limited
      to, attorneys' fees that are attributable to such claims or suit, provided
      that:  (i) TSMC gives Customer reasonably prompt notice in writing of any
      such claim or suit, and permits Customer, through counsel of its choice
      and reasonably acceptable to TSMC, to answer the charge of infringement
      and defend such claims or suit;  (ii) TSMC provides Customer information,
      assistance and authority at Customer's expense, to enable Customer to

                                       10
<PAGE>
 
   (c) If the court or a settlement enjoins the use of the Process by TSMC or,
       if, in TSMC's opinion, the Process or Products are likely to become the
       subject of a claim of infringement, TSMC shall, at its option, modify
       such Process so that it becomes non-infringing, substitute a
       substantially equivalent non-infringing process, obtain the right to
       continue using the Process under this Agreement, or subject to Subsection
       5(a) of the Option Agreement dated May 31, 1996, decline to furnish or to
