              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
              ----------------------------------------------------

     1.  The results of operations for the interim periods shown in this report
         are not necessarily indicative of results to be expected for the fiscal
         year.  In the opinion of management, the information contained herein
         reflects all adjustments necessary to make the results of operations
         for the interim periods a fair statement of such operations.  All such
         adjustments are of a normal recurring nature.

         The company uses a 52 to 53 week fiscal year ending on the Sunday
         closest to December 31. The quarters ended October 1, 1995 and
         September 25, 1994 included 13 weeks. The nine months ended October 1,
         1995 and September 25, 1994 included 40 and 39 weeks, respectively.

         Certain prior year amounts on the Condensed Consolidated Financial
         Statements have been reclassified to conform to the 1995 presentation.

     2.  AMD has three groundwater contamination sites that are on the Federal
         Superfund list.  The company is in the process of continuing clean-up
         of its sites.

     3.  The income tax rates used for the three months and nine months ended
         October 1, 1995 were 27 percent and 32 percent, respectively.  For the
         same periods in 1994 the company's income tax rate was approximately 33
         percent.  The lower rate in the third quarter of 1995 resulted from the
         company's change in its estimated income tax rate for the year from 33
         percent to 32 percent.

     4.  In 1993, the company and Fujitsu Limited established a joint venture,
         "Fujitsu AMD Semiconductor Limited (FASL)."  AMD's share of FASL is
         49.95 percent, and this investment is being accounted for under the
         equity method.  For the third quarter of 1995, the company's share of
         FASL's income was $12.3 million, net of an estimated income tax
         provision of approximately $6.6 million.  For the nine months ended
         October 1, 1995, the company's share of FASL's income was $13.4
         million, net of an estimated income tax provision of approximately $7.2
         million.  In the third quarter of 1995, FASL approved construction of a
         second flash memory fab, FASL II, at a site contiguous to the existing
         FASL facility in Aizu-Wakamatsu, Japan.  Ground-breaking on FASL II
         will be in the first quarter of 1996.

         Since the company's held-to-maturity securities are short-
         term in nature, changes in market interest rates would not have a
         significant impact on the fair value of these securities.  These
         securities are carried at amortized cost which approximates fair value.

         As of October 1, 1995, the company held $14.5 million of
         available-for-sale equity securities with a fair value of $44.9 million
         which are included in other assets.  The net unrealized gain on these
         equity securities is included in retained earnings.

         weighted average number of common shares outstanding plus dilutive
         common share equivalents.  The fully diluted computation also includes
         other dilutive convertible securities.  In the first quarter of 1995,
         the company called for redemption all outstanding shares of its
         Convertible Preferred Stock.  As a result, all of its outstanding
         Preferred Stock was either redeemed or converted to the company's
         common stock.  Shares used in the per share computations are as

     7.  On October 20, 1995, AMD and NexGen, Inc. (NexGen) signed a definitive
         agreement under which AMD would acquire NexGen in an all-stock
         transaction.  In accordance with the agreement NexGen shareholders will
         receive eight-tenths of a share of AMD common stock for each of
         NexGen's approximately 42 million shares of common stock outstanding, 
         common stock equivalents, and other potentially dilutive securities.
         The transaction is expected to be accounted for as a
         pooling of interests and structured as a tax free exchange. The
         transaction is expected to close in the first quarter of 1996.

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

     The following discussion should be read in conjunction with the attached
     condensed consolidated financial statements and notes thereto, and with the
     company's audited financial statements and notes thereto for the fiscal
     year ended December 25, 1994.

     RESULTS OF OPERATIONS
     ---------------------

     Net sales for the third quarter and first nine months of 1995, rose by 9
     percent and 16 percent, respectively, from the corresponding periods of
     1994. These increases were primarily attributable to growth in flash memory
     sales and secondarily due to an increase in sales of communication
     products.  Net sales for the third quarter of 1995 decreased 6 percent from
     the immediate prior quarter.  This decrease was primarily attributable to a
     decline in Am486(R) sales caused by significantly lower average selling
     prices.

     In the first nine months of 1995 compared to the same period of 1994, Am486
     microprocessor sales increased slightly due to a significant increase in
     unit shipments, offset by declines in average selling prices. In the third
     quarter of 1995 compared to the same quarter of 1994, Am486 microprocessor
     sales decreased significantly due to average selling price declines,
     partially offset by increases in unit sales. Am486 microprocessor sales
     also declined significantly from the second quarter of 1995 to the third
     quarter of 1995 due to decreases in average selling prices while unit
     shipments remained relatively flat. Price declines are anticipated to
     continue.

     Am486 microprocessor products contributed a significant portion of the
     company's revenues and profits in 1994 and 1995.  However, the company
     expects Am486 microprocessor revenues, margins, and profits in 1996 to be
     below those of 1995. AMD's microprocessor product revenues and profits will
     depend on the timing of new product introductions, market acceptance of new
     products, market demand, pricing pressures and the company's ability to
     meet demand.

     Flash memory was the company's highest revenue producing product line for
     the first time in the third quarter of 1995. Sales of flash memory devices
     for the third quarter and first nine months of 1995 increased significantly
     as compared to the same periods in the prior year primarily due to
     increased unit shipments.  The company plans to meet projected long-term
     demand for flash memory devices primarily through a manufacturing joint
     venture, Fujitsu AMD Semiconductor Limited (FASL).

     Revenues from communication products for the third quarter and first nine
     months of 1995 increased as compared to the same periods a year ago
     primarily due to growth in the Ethernet family of products. Sales of CMOS
     programmable logic devices in the third quarter and first nine months of
     1995 increased from comparable periods in 1994 primarily due to increased
     unit shipments.  For the third quarter and first nine months of 1995, EPROM
     sales decreased as compared to the same periods in 1994 primarily due to
     declines in market demand.

     Gross margins of 42 percent and 49 percent for the third quarter and first
     nine months of 1995 declined approximately 12 percent and 6 percent,
     respectively, from comparable periods in 1994.  The decreases in gross
     margin were attributable primarily to Am486 price decreases and secondarily
     to the purchase price of FASL products, which are higher than the costs of
     similar products manufactured internally.  The impact of gross margin
     declines caused by purchase of FASL products was partially offset by the
     company's share of FASL income. Pricing pressures on Am486 microprocessors
     are expected to continue.  Gross margin is also anticipated to decline
     further through 1995 due to increasing purchases from FASL and the
     transition of Fab 25 costs from research and development to cost of sales
     as production volumes increase.

     Research and development expenses increased in the third quarter and first
     nine months of 1995 from the corresponding periods in the prior year.
     These increases were primarily due to higher Fab 25 spending and
     secondarily due to increased microprocessor development cost. Research and
     development expenses remained relatively flat compared to the immediate
     prior quarter. Research and development expenses may decline for the
     remainder of 1995 as compared to the first nine months of 1995, as the
     allocation of Fab 25 costs shifts from research and development to cost of
     sales.

     Marketing, general, and administrative expenses remained relatively flat in
     the third quarter and first nine months of 1995 from the corresponding
     periods a year ago.

     The income tax rates used for the three months and nine months ended
     October 1, 1995 were 27 percent and 32 percent, respectively.  For the same
     periods in 1994 the company's income tax rate was approximately 33 percent.
     The lower rate in the third quarter of 1995 resulted from the company's
     change in its estimated income tax rate for the year from 33 percent to 32
     percent.

     International sales were 56 percent of total sales for the third quarter
     and 57 percent of total sales for the first nine months of 1995 as compared
     to 55 percent and 54 percent, respectively, for the comparable periods in
     1994.

     For the first three quarters of 1995, approximately 13 percent of the
     company's net sales were denominated in foreign currencies.  The company
     does not have sales denominated in local currencies in those countries
     which have highly inflationary economies.  The impact on the company's
     operating results from changes in foreign currency rates individually and
     in the aggregate has not been material.

     The company enters into foreign exchange forward contracts to buy and sell
     currencies as economic hedges of the company's foreign net monetary asset
     position.  In the third quarter of 1995, these hedging transactions were
     denominated in lira, yen, French franc, deutsche mark, and pound sterling.
     The maturities of these contracts are generally short-term in nature.  The
     company believes its foreign exchange contracts do not subject the company
     to material risk from exchange rate movements because gains and losses on
     these contracts are designed to offset losses and gains on the net monetary
     asset position being hedged.  Net foreign currency gains and losses have
     not been material.  As of October 1, 1995, the company had approximately
     $54.7 million (notional amount) of foreign exchange forward contracts.

     The company has engaged in interest rate swaps primarily to reduce its
     interest rate exposure by changing a portion of the company's interest rate
     obligation from a floating rate to a fixed rate basis.  At the end of the
     third quarter of 1995, the net outstanding notional amount of interest rate
     swaps was $190 million, of which $150 million will mature in 1996 and $40
     million will mature in 1997.  Gains and losses related to these interest
     rate swaps have been immaterial.

     The company primarily addresses market risk by participating as an end-user
     in various derivative markets to manage its exposure to interest and
     foreign currency exchange rate fluctuations.  The counterparties to the
     company's foreign exchange forward contracts, and interest rate swaps
     consist of a number of major, high credit quality, international financial
     institutions.  The company does not believe that there is significant risk
     of nonperformance by these counterparties because the company continually
     monitors the credit ratings of such counterparties, and reduces the
     financial exposure by limiting the amount of agreements entered into with
     any one financial institution.

     FINANCIAL CONDITION

     Cash, cash equivalents, and short-term investments increased by $115.1
     million from the end of 1994 to October 1, 1995.  This increase was
     primarily attributable to a $150 million term loan obtained in January of
     1995.  Cash generated from operating activities in the first three quarters
     of 1995 was offset by investments in property, plant and equipment to
     expand manufacturing capacity primarily related to Fab 25.  The company
     plans to continue to make significant capital investments throughout 1995
     and 1996, including an estimated $400 million for Fab 25 through the end of
     1996.

                                      11
<PAGE>
 
     Working capital increased by $49.1 million from $394.5 million at the end
     of 1994 to $443.6 million in the third quarter of 1995.  This increase was
     primarily due to higher cash, cash equivalents, and short-term investments.

     At the end of the third quarter of 1995, the company's total cash
     investment in FASL was $160.4 million as compared to $142.4 million at the
     end of 1994.  No additional cash investment is currently planned for the
     remainder of 1995.  In the first quarter of 1996, ground-breaking will
     begin on FASL II, a second flash memory fab planned for Aizu-Wakamatsu,
     Japan.  The planned $1.1 billion in capital expenditures for FASL II
     construction is expected to be funded by the anticipated income from FASL
     operations and bank borrowings by FASL.  However, in the event that FASL is
     unable to secure the necessary funds for FASL II, AMD is required to
     contribute cash or guarantee third-party loans in proportion to its
     percentage of interest in FASL.  The planned FASL II costs are denominated
     in yen and therefore are subject to change due to foreign exchange rate
     fluctuations.

     As of the end of the third quarter of 1995, the company had the following
     financing arrangements: unsecured committed bank lines of credit of $250
     million, unutilized; long-term secured equipment lease lines of $125
     million, which were fully utilized; short-term, unsecured uncommitted bank
     credit in the amount of $128 million, of which $25 million was utilized;
     and an outstanding $150 million four-year term loan.

     The company's current capital plan and requirements are based on various
     product-mix, selling-price and unit-demand assumptions and are, therefore,
     subject to revision due to future market conditions.

     On May 25, 1994, the Securities and Exchange Commission declared effective
     the company's shelf registration statement covering up to $400 million of
     its securities, which may be either debt securities, preferred stock,
     depositary shares representing fractions of shares of preferred stock,
     common stock, warrants to purchase common stock, or any combination of the
     foregoing which the company may offer from time to time in the future. To
     date, the company has not offered or sold any securities registered under
     the $400 million registration statement.  The nature and terms of the
     securities will be established at the time of their sale.  The company may
     offer the securities through underwriters to be named in the future,
     through agents or otherwise.  It is presently expected that the net
     proceeds of any offering would be used for general corporate purposes
     including but not limited to the reduction of outstanding indebtedness,
     working capital increases and capital expenditures.

     The company believes that cash flows from operations and current cash
     balances, together with current and anticipated available long-term
     financing, will be sufficient to fund operations and capital investments
     currently planned for the remainder of 1995 and 1996.

     FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS AND FINANCIAL
     CONDITION

     The semiconductor industry is generally characterized by a highly
     competitive and rapidly changing environment in which operating results are
     often subject to the effects of new product introductions, manufacturing
     technology innovations, rapid fluctuations in product demand, the
     availability of manufacturing capacity, and the ability to secure and
     maintain intellectual property rights.  While the company attempts to
     identify and respond to rapidly changing events and conditions as soon as
     possible, the anticipation of and reaction to such events are an ongoing
     challenge.

     The company believes that its future results of operations and financial
     condition could be impacted by any of the following factors: market
     acceptance and timing of new products; continued market acceptance of
     personal computer industry standards applicable to the company's products;
     trends in the personal computer marketplace; capacity constraints; intense
     price competition; interruption in procuring needed manufacturing
     materials; disruption of manufacturing facilities; the company's ability to
     access financing in the debt and equity markets; and changes in domestic
     and international economic conditions.

     Although Am486 microprocessors have significantly contributed to the
     company's revenues and profits, there can be no assurance that there will
     be continued market acceptance of Am486 microprocessors.  A gap in time
     between the cessation of market demand for Am486 microprocessors and volume
     availability of AMD's next generation of microprocessors could have a
     material adverse effect on the company's financial results.  The company's
     next generation K86 RISC SUPERSCALAR(TM) products are being designed to be
     Microsoft(R) Windows(R)-compatible and to compete with Intel's post-486
     generations of X86 microprocessors, including the Pentium and the Pentium
     Pro. Volume production of the initial K86(TM) products, a 75 MHz device
     tentatively known as the SSA/5-75, is anticipated to begin in the first
     half of 1996.  K86 products designed to achieve a performance advantage
     over existing Pentium microprocessors are expected to be in volume
     production in the second half of 1996.  There can be no assurance that the
     company will be able to introduce its K86 products in a timely manner to
     meet competition, that these microprocessors will not face severe price
     competition, that these microprocessors will achieve planned design
     performance, or that superior competitive products will not be introduced.
     There can be no assurance that the K86 products will achieve market
     acceptance or desired financial results.  Any such failure could materially
     adversely affect the company's future operating results.

     The substantial resources which the company has devoted to the development
     of the AMD-K5(TM) in the third quarter of 1995 has impacted the company's
     efforts to develop successive generation products, such as those designed
     to compete with the Pentium Pro and Intel's subsequent generation products.
     To the extent that the 

                                      13
<PAGE>
 
     introduction of each generation of K86 products is delayed, the company's
     revenues, margins and profits will be materially adversely affected.

     Compaq Computer Corporation ("Compaq") has advised the company that it is
     reviewing its practice of purchasing microprocessors from suppliers
     other than Intel, and is in the process of determining whether it will
     purchase microprocessors from suppliers other than Intel in the near term.
     The company believes that Compaq will consider the purchase of the
     company's K86 microprocessors when they become available, but no assurance
     can be given that any purchases will be made by Compaq or, if they are,
     that they will not be terminated by Compaq due to the availability of
     competing microprocessor products.

     On October 20, 1995, the company and NexGen, Inc. ("NexGen") executed an
     Agreement and Plan of Merger (the "Merger Agreement", a copy of which is
     attached to this report). A more complete discussion concerning the Merger
     Agreement is set forth in item 5 of this Report. The company has announced
     its intention to bring to production status NexGen's sixth-generation
     Nx686(TM) design in order to market the product as the AMD-K6(TM)
     microprocessor, the next generation of the AMD K86 SUPERSCALAR series. The
     company has also announced its intention to cease activity on its own 
     sixth-generation design project in order to devote its related resources to
     future microprocessor generations. As a result, if the transaction provided
     for in the Merger Agreement were not to occur, the company would experience
     significant delays in bringing its own sixth-generation microprocessor
     product to production status.

     The company has entered into a number of licenses and cross-licenses
     relating to several of the company's products.  As is common in the
     semiconductor industry, from time to time the company has been notified
     that it may be infringing other parties' patents or copyrights.  While
     patent and copyright owners in such instances often express a willingness
     to resolve the dispute or grant a license, no assurance can be given that
     all necessary licenses will be honored or obtained on satisfactory terms,
     nor that the ultimate resolution of any material dispute concerning the
     company's present or future products will not have an adverse impact on the
     company's future results of operations or financial condition.

     Due to the factors noted above, the company's future operations, financial
     condition, and stock price may be subject to volatility.  In addition, an
     actual or anticipated shortfall in revenue, gross margins, or earnings from
     securities analysts' expectations could have an immediate adverse effect on
     the trading price of the company's common stock in any given period.

     II.  OTHER INFORMATION

     Item 5.     Other Information

     On October 20, 1995, the company and NexGen, Inc. ("NexGen") executed an
     Agreement and Plan of Merger (the "Merger Agreement").  Under the terms of
     the Merger Agreement, a wholly owned subsidiary of the company would be
     merged into NexGen (the "Merger"), and NexGen would become a wholly owned
     subsidiary of the company.  Upon consummation of the Merger, each issued
     and outstanding share of the Common Stock of NexGen would be converted into
     the right to receive eight-tenths (0.8) of a share of the Common Stock of
     the Company. NexGen has approximately 42 million shares of common stock
     outstanding, common stock equivalents, and other potentially dilutive
     securities. The transaction is intended to be a tax free exchange for
     NexGen's stockholders.

     If approved, the transaction is expected to close in the first quarter of
     calendar 1996.  There can be no assurance, however, that the transaction
     will be consummated.  The consummation of the transaction is subject to
     customary conditions, including shareholders' approval and clearance by
     governmental agencies.

     Stockholders of NexGen holding approximately 38% of its outstanding Common
     Stock have executed Voting Agreements pursuant to which they have agreed to
     vote their shares in favor of the Merger.

     Concurrently with the execution of the Merger Agreement, the company and
     NexGen also executed a Secured Credit Agreement (the "Credit Agreement")
     pursuant to which the company has agreed to provide NexGen with a revolving
     line of credit in the aggregate principal amount of up to $30,000,000 until
     December 31, 1995, up to $50,000,000 from January 1, 1996, until March 31,
     1996, and up to $60,000,000 from April 1, 1996, until June 30, 1996.
     Borrowings under the Credit Agreement will bear interest at prime plus 3.5%
     and will be secured by all tangible and intangible assets of NexGen, but
     will be subordinated to the existing senior indebtedness of NexGen.  All
     outstanding principal and accrued interest on borrowings under the Credit
     Agreement are due 12 months after the termination of the Merger Agreement
     for any reason, or earlier if and when any person other than the company
     acquires more than 50% of NexGen's outstanding Common Stock but in any 
     event not later than June 30, 1997.

                         AGREEMENT AND PLAN OF MERGER
                         ----------------------------

     AGREEMENT AND PLAN OF MERGER (the "Agreement") dated as of October 20,
1995, by and among ADVANCED MICRO DEVICES, INC., a Delaware corporation
(hereinafter referred to as "AMD"), AMD MERGER CORPORATION, a Delaware
corporation (hereinafter referred to as "AMD Merger"), and NEXGEN, INC., a
Delaware corporation (hereinafter referred to as "NexGen").

     A.  AMD has formed AMD Merger as a wholly-owned subsidiary in order to
effect the merger of AMD Merger with and into NexGen (the "Merger") in
accordance with the laws of the State of Delaware and in accordance with this
Agreement so that upon consummation of the Merger, NexGen will be a wholly-owned
subsidiary of AMD and AMD Merger will cease to exist; and

     B.  This Agreement has been approved by the Boards of Directors of AMD, AMD
Merger and NexGen, by AMD in its capacity as the sole stockholder of AMD Merger,
and will be submitted for approval by the stockholders of AMD and NexGen; and

     C.  The Merger is intended to qualify as a tax-free reorganization within
the meaning of the provisions of Section 368 of the Internal Revenue Code of
1986, as it may be amended from time to time (the "Code"); and

     D.  AMD and NexGen have entered into a Credit Agreement, dated as of the
date hereof, in the form attached hereto as Annex 1 and forming an integral part
of this Agreement (the "Credit Agreement").

     NOW, THEREFORE, in consideration of their mutual covenants, promises and
obligations contained in this Agreement and the Credit Agreement, the parties
hereto agree as follows:

                                   SECTION 1

                                  THE MERGER

     1.1  Merger.  At the Effective Time (as hereinafter defined) AMD Merger
          ------
shall be merged with and into NexGen, whereupon the separate existence of AMD
Merger shall cease, and NexGen shall be the surviving corporation. The above
notwithstanding, at the election of AMD, the Merger shall be restructured such
that either (i) NexGen shall be merged with and into AMD, whereupon the separate
existence of NexGen shall cease, AMD shall be the surviving corporation, and AMD
Merger shall not be a constituent corporation of the Merger, or (ii) NexGen
shall be merged with and into AMD Merger, whereupon the separate existence of
NexGen shall cease, and AMD Merger shall be the surviving corporation; provided,
however, that in each case, AMD's right to elect an alternative structure shall
be subject to the condition that the
     
                                       1

<PAGE>
 
 
Merger will qualify as a tax-free reorganization within the meaning of the
provisions of Section 368 of the Code.

     1.2  Closing.  The transactions contemplated by this Agreement shall be
          -------
consummated at a closing (the "Closing") which will take place at the offices of
Bronson, Bronson & McKinnon, 505 Montgomery Street, San Francisco, California as
soon as practicable after the respective stockholders of AMD and NexGen shall
have approved the Merger, as provided in Section 1.9 of this Agreement;
provided, however, that if any condition of Closing specified in Sections 7
through 9 has not been satisfied, NexGen or AMD, as the case may be, may
postpone the Closing until a date which is promptly after the satisfaction of
such condition, but in no event shall such postponement extend beyond June 30,
1996. Notwithstanding the foregoing, the Closing may take place at such other
place, time or date as may be agreed upon by NexGen and AMD. The date of the
Closing is referred to in this Agreement as the "Closing Date."

     1.3  Consummation of Transactions.  If, at the Closing, no condition exists
          ----------------------------                                          
which would permit any of the parties to terminate this Agreement or a condition
then exists and the party entitled to terminate because of that condition elects
not to do so, then the Merger shall be consummated, and then and thereupon AMD
Merger and NexGen will each carry out the procedures specified under the
applicable provisions of the Delaware General Corporation Law, as amended (the
"DGCL"), including filing a Certificate of Merger with the Secretary of State of
the State of Delaware, whereupon the Merger shall become effective.  The time
that the Merger shall become effective is referred to in this Agreement as the
"Effective Time."

     1.4  Effect of Transactions.  The Merger shall have the effects set forth
          ----------------------                                              
in Section 259 of the DGCL.

     1.5  Conversion of NexGen Common Stock. (a) At the Effective Time, (i) each
          ---------------------------------                                     
issued and outstanding share of NexGen common stock, par value $.0001 per share
("NexGen Common Stock") shall cease to be an existing and issued share and shall
become and be converted into, by virtue of the Merger and without any action on
the part of the holder thereof, the right to receive, upon surrender of the
certificate representing such share and in exchange therefor, 8/10th's of a
share (the "Exchange Ratio") of AMD common stock, $.01 par value ("AMD Common
Stock"); such shares shall be fully paid and nonassessable; and (ii) each issued
and outstanding share of AMD Merger Common Stock, par value $.01 per share,
shall be converted into one (1) issued and outstanding share of NexGen Common
Stock.

     (b)  In the case of any consolidation or merger of AMD with or into another
corporation other than a merger with another corporation in which AMD is a
continuing corporation and which

                                       2

<PAGE>
 
does not result in any reclassification or change of AMD Common Stock, at the
Effective Time, (i) each issued and outstanding share of NexGen Common Stock
shall cease to be an existing and issued share and shall become and be converted
into, by virtue of the Merger and without any action on the part of the holder
thereof, the right to receive, upon surrender of the certificate representing
such share and in exchange therefor, 8/10th's of the kind and amount of shares
of stock or other securities receivable upon such consolidation or merger by a
holder of one (1) share of AMD Common Stock; such securities shall be fully paid
and nonassessable; and (ii) each issued and outstanding share of AMD Merger
Common Stock, par value $0.01 per share, shall be converted into one (1) issued
and outstanding share of NexGen Common Stock.  Upon any such consolidation or
merger, to the extent reasonably deemed necessary by NexGen, AMD or the
successor corporation shall execute appropriate documentation to insure the
result provided for in this Section 1.5(b).

     1.6  Surrender and Payment.  (a) Prior to the Effective Time, AMD shall
          ---------------------                                             
appoint an agent reasonably satisfactory to NexGen (the "Exchange Agent") for
the purpose of exchanging certificates representing shares of NexGen Common
Stock as provided in Section 1.5.  At the Effective Time, AMD will deposit with
the Exchange Agent certificates representing the aggregate number of shares of
AMD Common Stock to be issued in respect of shares of NexGen Common Stock.
Promptly after the Effective Time, AMD will send, or will cause the Exchange
Agent to send, to each holder of shares of NexGen Common Stock at the Effective
Time a letter of transmittal for use in such exchange (which shall specify that
the delivery shall be effected, and risk of loss and title shall pass, only upon
proper delivery of the certificates representing shares of NexGen Common Stock
to the Exchange Agent.

     (b)  Each holder of shares of NexGen Common Stock that have been converted
into a right to receive shares of AMD Common Stock upon surrender to the
Exchange Agent of a certificate or certificates representing such shares of
NexGen Common Stock, together with a properly completed letter of transmittal
covering such shares, will be entitled to receive the shares of AMD Common Stock
issuable in respect of such shares.  Until so surrendered, each such certificate
shall, after the Effective Time, represent for all purposes only the right to
receive such shares of AMD Common Stock.

     (c)  If any shares of AMD Common Stock are to be paid to a person other
than the registered holder of the shares of NexGen Common Stock represented by
the certificate or certificates surrendered in exchange therefor, it shall be a
condition to such payment that the certificate or certificates so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the person requesting such payment shall pay to the

                                       3

<PAGE>
 
Exchange Agent any transfer or other taxes required as a result of such payment
to a person other than the registered holder of such shares of NexGen Common
Stock or establish to the satisfaction of the Exchange Agent that such tax has
been paid or is not payable.

     (d)  After the Effective Time, there shall be no further registration of
transfers of shares of NexGen Common Stock.  If, after the Effective Time,
certificates representing shares of NexGen Common Stock are presented to NexGen
or AMD, they shall be canceled and exchanged for shares of AMD Common Stock in
accordance with the procedures set forth herein.

     (e)  Any shares of AMD Common Stock deposited with the Exchange Agent
pursuant to Section 1.6(a) that remain unclaimed by the holders of shares of
NexGen Common Stock twelve months after the Effective Time shall be returned to
AMD upon demand, and any such holder who has not exchanged his shares of NexGen
Common Stock for AMD in accordance with this Section 1.6 prior to that time
shall thereafter look only to AMD for his claim for AMD Common Stock, any cash
in lieu of fractional shares of AMD Common Stock and any dividends or
distributions with respect to AMD Common Stock.  Notwithstanding the foregoing,
AMD shall not be liable to any holder of shares of AMD Common Stock for any
amount paid to a public official pursuant to applicable abandoned property laws.

     (f)  No dividends or other distributions with respect to the AMD Common
Stock to be issued in the Merger shall be paid to the holder of any
unsurrendered certificates representing shares of NexGen Common Stock until such
certificates are surrendered as provided in this Section 1.6.  Upon such
surrender, there shall be paid, without interest, to the holder of the AMD
Common Stock into which such shares of NexGen Common Stock were converted, (1)
all dividends and other distributions in respect of AMD Common Stock that are
payable on a date subsequent to, and the record date for which occurs after, the
Effective Time, and (2) all dividends or other distributions in respect of
shares of NexGen Common Stock that are payable on a date subsequent to, and the
record date for which occurs before, the Effective Time.

     1.7  Fractional Shares.  No fractional shares of AMD Common Stock will be
          -----------------                                                   
issued in connection with the Merger and no certificate therefor will be issued.
In lieu of such fractional shares, any holder of NexGen Common Stock who would
otherwise be entitled to a fraction of a share of AMD Common Stock shall, upon
surrender of his certificate or certificates representing NexGen Common Stock,
be paid an amount in cash (without interest) determined by multiplying such
fraction by the average of the last reported sales price, regular way, of AMD
Common Stock on the New York Stock Exchange (the "NYSE") for the twenty trading
days immediately preceding the Closing.  The Exchange Agent will,

                                       4

<PAGE>
 
subject to any applicable abandoned property or similar law, until one year
after the Effective Time, pay to such holders, upon surrender of their
certificates, representing NexGen Common Stock outstanding immediately prior to
the Effective Time, the cash value of such fractions so determined, without
interest.  This obligation shall be assumed by AMD one year after the Effective
Time subject to any applicable statute of limitations or any abandoned property
or similar law.

     1.8  Assumption of Stock Options and Warrants.  At the Effective Time, all
          ----------------------------------------                             
options or rights to purchase NexGen Common Stock then outstanding under the
NexGen 1995 Employee Stock Purchase Plan, the NexGen 1987 Stock Plan, and the
NexGen 1995 Stock Plan (the "NexGen Options"), all outstanding warrants to
purchase NexGen Common Stock (the "NexGen Warrants") and the option of ASCII to
acquire NexGen Common Stock under the ASCII Notes described in Section 2.2(b)
shall be assumed by AMD in accordance with the provisions of Section 5.3 hereof.

     1.9  Stockholders' Approvals.  AMD and NexGen shall each call a meeting of
          -----------------------

Agreement and the Merger contemplated hereby (the "AMD Stockholders' Meeting"
and the "NexGen Stockholders' Meeting"), all in accordance with the provisions
of the DGCL and the Securities Exchange Act of 1934, as amended ("the Exchange
Act"), as soon as practicable after AMD's registration statement on Form S-4
relating to the shares of AMD Common Stock to be issued in connection with the
Merger (the "S-4") shall have been declared effective by the Securities and
Exchange Commission (the "SEC") and the Proxy Statement, as defined in Section
4.2(c), has been cleared by the SEC.

          ----------------------------------------------------------------

Stock which are received in the Merger in exchange for shares of NexGen Common
Stock which, under agreements with NexGen or its subsidiaries, are unvested or
subject to a repurchase option or other condition of forfeiture which, by its
terms, does not terminate due to the Merger will also be unvested or subject to
the same repurchase option or other condition, as the case may be, and the
certificates evidencing such shares will be marked with appropriate legends.

                                   SECTION 2

                   REPRESENTATIONS AND WARRANTIES OF NEXGEN

     Except as set forth in the schedule of disclosures and exceptions delivered
to AMD contemporaneously with the execution of this Agreement and initialled by
an officer of NexGen (the "NexGen Disclosure Schedule"), the sections of which
are numbered to correspond to the section numbers of this Agreement, NexGen
represents and warrants to AMD and AMD Merger as follows:

     2.1  Organization; Qualification.  NexGen is a corporation duly organized,
          ---------------------------                                          
validly existing and in good standing under the laws of the State of Delaware.
NexGen has all requisite corporate power and authority to own, lease and operate
its properties and to carry on its business as now being conducted and is duly
qualified and in good standing to do business as a foreign corporation in each
jurisdiction in which the property owned, leased or operated by it or the nature
of the business conducted by it makes such qualification necessary, except where
the failure to have such power and authority or to be so duly qualified and in
good standing would not, in the aggregate, have a material adverse effect on the
business, operations or financial condition of NexGen.  NexGen has previously
delivered to AMD complete and correct copies of NexGen's Certificate of
Incorporation and Bylaws.

     2.2  Capitalization.
          -------------- 

          (a) NexGen's authorized capital stock consists of 125,000,000 shares

validly existing and in good standing under the laws of the jurisdiction of its
incorporation.  Each of the NexGen Subsidiaries has all requisite corporate
power and authority to own, lease and operate its properties and to carry on its
business as now being conducted and is duly qualified and in good standing to do
business as a foreign corporation in each jurisdiction in which the nature of
its business or the owning or leasing of its properties makes such qualification
necessary, except where the failure to have such power and authority or to be so
qualified would not, in the aggregate, have a material adverse effect on the
assets, properties, business or financial condition of NexGen and the NexGen
Subsidiaries taken as a whole.

     2.4  Authority Relative to Agreements.  NexGen has full corporate power and

reason why any required permit, authorization, consent or approval will not be
obtained.  Neither the execution and delivery of this Agreement or the Credit

contemplated by this Agreement or the Credit Agreement will (a) conflict with or
result in any breach of any provision of the Certificate of Incorporation or
Bylaws of NexGen, (b) result in a breach of or constitute a default (or an event

     descriptions" and "summaries of material modifications" (as defined in
     Section 102 of ERISA and the regulations thereunder) prepared in connection

     Subsidiaries is a participant in any "multi-employer plan" within the
     meaning of Section 4001(a)(3) of ERISA.

          (b)  Section 2.14(b) of the NexGen Disclosure Schedule lists all

     salary and base wages), bonus, stock option, stock purchase, incentive,
     vacation, health, dental, disability and death benefits which NexGen or any
     of the NexGen Subsidiaries maintains or administers, or to which NexGen or
     any of the NexGen Subsidiaries contributes or is required to contribute, or
     with respect to which NexGen has or may incur any present or future
     obligation. True and correct copies of all such plans, agreements or
     arrangements (hereinafter referred to collectively as "NexGen Benefit
     Arrangements") have been furnished to AMD.

          (c)  Each Employee Benefit Plan (and any related trust agreements,
     annuity contracts and other funding instruments) has been and is being
     administered and operated in accordance with its terms and has complied,
     and complies currently, in all material respects, with the provisions of

                                       15

     ERISA and of the Code and all other applicable laws, rules and regulations.
     Each NexGen Benefit Arrangement has been and is being administered and
     operated in accordance with its terms and has complied, and currently
     complies, with the provisions of all applicable laws, rules and
     regulations.  All reports required by any governmental agencies have been
     timely filed with respect to all Employee Benefit Plans and all NexGen
     Benefit Arrangements.

          Each Employee Benefit Plan which is intended to be tax qualified under
     Section 401(a) or Section 403 of the Code is so qualified and has received
     a favorable determination letter, covering all amendments thereto, from the
     IRS indicating that it is so qualified.  Each trust which is intended to be
     tax-exempt--under Section 501(a) of the Code is exempt from taxation.

          (d)  No "prohibited transaction," as defined in Section 406 of ERISA
     and Section 4975 of the Code, has occurred with respect to any Employee
     Benefit Plan which could subject any person or entity (other than a person
     or entity for whom NexGen or any of the NexGen Subsidiaries is not directly
     or indirectly responsible) to liability under Title I of ERISA or to the
     imposition of any tax under Section 4975 of the Code.

          (e)  Other than for claims in the ordinary course for benefits under
     any and all Employee Benefit Plans or NexGen Benefit Arrangements, there
     are no actions, suits, claims or proceedings pending or, to the best
     knowledge of NexGen, threatened, nor does there exist any basis therefor,
     which could result in any material liability on the part of NexGen or any
     NexGen Subsidiary with respect to any Employee Benefit Plan or NexGen
     Benefit Arrangement.

          (f)  Neither NexGen nor any NexGen Subsidiary maintains any Employee
     Benefit Plan subject to Title IV of ERISA.

          (g)  There has been no amendment to, or changes in the actuarial
     assumptions or funding of, any Employee Benefit Plan or NexGen Benefit
     Arrangement which would materially increase the annual expense associated
     with such plan or arrangement above the level of the expense set forth in
     the NexGen Consolidated Statement of Operations for the fiscal year ended
     June 30, 1995.

     such items have been registered.  Section 2.15(a) of the NexGen Disclosure
     Schedule includes and specifically identifies all third-party patents,
     trademarks, copyrights (including software) and maskworks (the "Third Party
     Intellectual Property Rights"), to the knowledge of NexGen, which are
     incorporated in, are, or form a part of, any NexGen product.  Section

     Rights by or through NexGen, are currently pending or, to the knowledge of
     NexGen, are threatened by any person, nor does NexGen know of any valid
     grounds for any bona fide claims (i) to the effect that the manufacture,
     sale, licensing or use of any product as now used, sold or licensed or
     proposed for use, sale or license by NexGen infringes on any copyright,
     maskwork,  patent, trademark, service mark or trade secret; (ii) against
     the use by NexGen of any trademarks, trade names, trade secrets,

     Rights.  To NexGen's knowledge, after reasonable investigation, all
     patents, registered trademarks, maskworks and copyrights held by NexGen are
     valid and subsisting.  To NexGen's knowledge, there is no material
     unauthorized use, infringement or misappropriation of any of the NexGen
     Intellectual Property by any third party, including any employee or former
     employee of NexGen or any of the NexGen Subsidiaries.  Neither NexGen nor
     any of the NexGen Subsidiaries (i) has been sued or charged in writing as a
     defendant in any claim, suit, action or proceeding which involves a claim
     or infringement of trade secrets, any  patents, trademarks, service marks,

     the date hereof or been informed or notified by any third party that NexGen
     may be engaged in such infringement or (ii) has knowledge of any
     infringement liability with respect to, or infringement by, NexGen or any
     of the NexGen Subsidiaries of any trade secret, patent, trademark, service
     mark, maskwork or copyright of another.

          (c)  Neither the execution and delivery of this Agreement or the
     Credit Agreement by NexGen nor the consummation by NexGen of the
     transactions contemplated by this Agreement or the Credit Agreement will
     result in any breach of or constitute a default (or an event that with
     notice or lapse of time or both would become a default), or impair NexGen's
     or any of the NexGen Subsidiaries' rights or alter the rights or
     obligations of any third party under, or give to others any rights of
     termination, amendment, acceleration or cancellation of, any license
     agreement, contract or other arrangement of any nature relating to NexGen
     Intellectual Property Rights or Third Party Intellectual Property Rights.

Balance Sheet as owned by it and to properties or assets acquired by it or a
NexGen Subsidiary after the date thereof (except for equipment which is subject
to capital leases and properties sold or otherwise disposed of in the ordinary
course of business since the date of the NexGen Audited Balance sheet), free and
clear of all title defects and all liens, mortgages, pledges, claims, charges,
security interests or other encumbrances of any nature whatsoever except as

materially detract from the value, or materially interfere with the present use,

the NexGen Subsidiaries as a whole or otherwise materially impair the business
of NexGen and the NexGen Subsidiaries as a whole.

on its officers, directors, employees, business operations and property, in such
amounts as are reasonable and deemed adequate by its Board of Directors or
management, against all risks usually insured against by persons operating
similar properties or businesses in the localities where such properties are
located, under, to the best of NexGen's knowledge, valid and enforceable
policies issued by insurers of recognized responsibility, and such policies
shall not, pursuant to their terms, in any way be affected by, or terminate or

     currently conducted in any material respect. The term "AMD Intellectual
     Property Rights" as used in this Section 3.15 means all current and past

     Party Intellectual Property Rights to the extent arising out of any use,
     reproduction or distribution of such Third Party Intellectual Property
     Rights by or through AMD, are currently pending or, to the knowledge of
     AMD, are threatened by any person, nor does AMD know of any valid grounds
     for any bona fide claims (i) to the effect that the manufacture, sale,

     for use, sale or license by AMD infringes on any copyright, maskwork,
     patent, trademark, service mark or trade secret; (ii) against the use by
     AMD of any trademarks, trade names, trade secrets, copyrights, maskworks,

     effectiveness of any of AMD's Intellectual Property Rights or other trade

     knowledge, after reasonable investigation, all patents, registered
     trademarks, maskworks and copyrights held by AMD are valid and subsisting.
     To AMD's knowledge, there is no material unauthorized use, infringement or
     misappropriation of any of the AMD Intellectual Property by any third
     party, including any employee or former employee of AMD or any of the AMD
     Subsidiaries.  Neither AMD nor any of the AMD Subsidiaries (i) has been
     sued or charged in writing as a defendant in any claim, suit, action or
     proceeding which involves a claim or infringement of trade secrets, any
     patents, trademarks, service marks, maskworks or copyrights and which has
     not been finally terminated prior to the date hereof or been informed or
     notified by any third party that AMD may be engaged in such infringement or
     (ii) has knowledge of any infringement liability with respect to, or

     the rights or obligations of any third party under, or give to others any
     rights of termination, amendment, acceleration or cancellation of, any
     license agreement, contract or other arrangement of any nature relating to
     AMD Intellectual Property Rights or Third Party Intellectual Property

Balance Sheet as owned by AMD and to properties or assets acquired by AMD or any
AMD Subsidiary after the date thereof (except for equipment which is subject to
capital leases and properties sold or otherwise disposed of in the ordinary
course of business since the date of the AMD Unaudited Balance sheet), free and
clear of all title defects and all liens, mortgages, pledges, claims, charges,
security interests or other encumbrances of any nature whatsoever except as
stated in the AMD Annual Reports or the AMD Quarterly Reports, or which alone or
in the aggregate do not materially detract from the value, or materially
interfere with the present use, of any material asset or property or of the
assets or properties of AMD and the AMD Subsidiaries as a whole or otherwise
materially impair the business of AMD and the AMD Subsidiaries as a whole.

     3.17  Insurance.  AMD and each of the AMD Subsidiaries has insurance on its
           ---------                                                            
officers, directors, employees, business operations and property, in such
amounts as are reasonable and deemed adequate by its Board of Directors or
management, against all risks usually insured against by persons operating
similar properties or businesses in the localities where such properties are
located, under, to the best of AMD's knowledge, valid and enforceable policies
issued by insurers of recognized responsibility, and such policies shall not,
pursuant to their terms, in any way be affected by, or terminate or lapse by
reason of, the Merger.  AMD has not done anything, either by way of action or
inaction, that might invalidate, in whole or in part, any of the material
policies of fire, casualty, liability, title, workers' compensation and other
forms of insurance held by AMD.

     3.18  Transactions with Management.  Except as disclosed in the documents

indirect material interest in (i) any property or assets of AMD or that of any

customer, supplier or agent of AMD or any of the AMD Subsidiaries, or (iii) any
person which is a party to any contract or agreement which is material to AMD or
any of the AMD Subsidiaries.

     3.19 Disclosure.  No representations or warranties by AMD in this Agreement
          ----------

of AMD, any other person, contained in any document, certificate or other
writing furnished by AMD to NexGen in connection with the preparation of the
Proxy Statement or the S-4, contains any untrue statement of a material fact or
omits any material fact necessary to make the statements made herein or therein,
in light of the circumstances under which they were made, not misleading.

           ---------------------------                                          
any liability for brokerage or finders' fees or agents commissions in connection
with this Agreement or the Merger other than fees agreed to be paid to
Donaldson, Lufkin & Jenrette Securities Corporation in consideration for
investment banking advice and the rendering of a fairness opinion with respect
to the Merger.  AMD has provided NexGen with a true copy of the agreement
between AMD and Donaldson, Lufkin & Jenrette Securities Corporation regarding
the services to be rendered by Donaldson, Lufkin & Jenrette Securities
Corporation in connection with the Merger, and the fee to be paid to Donaldson,
Lufkin & Jenrette Securities Corporation will not exceed $ 4,500,000 plus
expenses.  AMD has received the fairness opinion rendered by Donaldson, Lufkin &
Jenrette Securities Corporation, and a copy of such opinion is attached to the
AMD Disclosure Schedule.

     3.21  Actions Affecting Pooling.  Aside from any actions contemplated this
           -------------------------                                           
Agreement, AMD has not taken or permitted any action relating to AMD which would
prevent the Merger from qualifying for pooling-of-interests accounting treatment
in accordance with generally accepted accounting principles and all rules,
regulations and policies of the SEC.

           ---------------------
aggregate have not had and could not reasonably be expected to have a material
adverse effect on AMD, AMD and each of the AMD Subsidiaries to the best of AMD's
knowledge (i) have obtained all applicable permits, licenses and other
authorizations which are required under federal, state, provincial or local laws
relating to pollution or protection of the environment, including laws relating

by AMD or the AMD Subsidiaries (or their respective agents); (ii) are in
compliance with all the terms and conditions of such required permits, licenses
and authorization, and also are in compliance with all other limitations,

or statutory liability, or otherwise form the basis of any claim, action, suit
or proceeding, based on or resulting from AMD's or any AMD Subsidiary's (or any
of their respective agents) manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling, or the emission, discharge
or release into the environment, of any pollutant, contaminant or hazardous or
toxic material or waste; and (iv) have taken all actions necessary under
applicable requirements of federal, state or local laws, rules or regulations to
register any products or materials required to be registered by AMD or the AMD

     3.24 NexGen Commercial Relationships.  AMD and AMD Merger have no reason to
          -------------------------------                                       
believe that either IBM or VLSI will elect not to continue their relationship
with NexGen following the Effective Time.

                                   SECTION 4

                              COVENANTS OF NEXGEN

     NexGen hereby covenants and agrees as follows:

     4.1  Negative Covenants.  Between the date of this Agreement and the
          ------------------                                             
Effective Time, unless AMD shall otherwise consent in

                                       35

<PAGE>
 
writing, which consent AMD may not unreasonably withhold, neither NexGen nor any
NexGen Subsidiary will do any of the following or commit to do so:

          (a)  Make any purchase, sale or disposition of any material asset or
     property or mortgage, pledge, subject to a lien or otherwise encumber any
     of its material properties or assets, other than in the ordinary course of

          (b)  Except for obligations under existing contracts and agreements,

     from being eligible for pooling-of-interests accounting treatment in
     accordance with generally accepted accounting principles and all rules,
     regulations and policies of the SEC, and NexGen will use its best efforts
     to prevent any of its officers or directors from taking or permitting any
     such action;

     Incorporation or Bylaws, offer to issue or issue any shares of its capital

     options, warrants or rights to acquire any capital stock of NexGen (other
     than grants of options pursuant to existing employee benefit programs in a
     manner which is consistent with past practice), or accelerate the
     exercisability or vesting of options or warrants presently outstanding,
     except (i) acceleration which occurs automatically pursuant to the terms of
     an existing agreement between NexGen and a holder of NexGen Options or
     NexGen Warrants and (ii) to provide that any presently outstanding options
     or warrants shall not terminate merely by reason of the Merger;

          (e)  Declare, set aside or pay any dividend or make any other
     distribution in respect of its capital stock, or make any direct or
     indirect redemption, purchase or other acquisition of its capital stock
     (other than in connection with the repurchase of stock from terminated
     employees or the surrender of stock to NexGen for the purpose of a stock-
     for-stock exercise of an employee stock option);

          (f)  Make any change in the compensation payable or to become payable
     to any of its directors, officers or employees (other than increases in

     increases which are consistent with past practice) or enter into or amend
     any indemnity, employment or consulting agreements;

          (g)  Make any loans to any of its stockholders, officers, directors or
     employees or make any change in its borrowing arrangements;

     agreements not entered into in the ordinary course of business;

          (i)  Undertake any change in the capital structure of NexGen or of any
     NexGen Subsidiary or in the operational or management structure of NexGen
     and the NexGen Subsidiaries as a whole;

          (j)  Undertake a course of action inconsistent with this Agreement or
     which would prevent any conditions precedent to its obligations under this
     Agreement from being satisfied at or prior to the Effective Time;

          (k)  Provide or publish to its stockholders any material which might
     constitute an unauthorized "prospectus" within the meaning of the

          (l)  Violate the terms of the Credit Agreement;

          (m)  Issue any press release or any public disclosure, either written
     or oral, of the transactions contemplated by this Agreement or negotiations
     related thereto without the prior knowledge and written consent of AMD,
     which consent shall not be unreasonably withheld; provided, however, that
     no such consent shall be required if NexGen has determined in good faith
     upon written advice of counsel that it is required under applicable
     securities laws to make the disclosure; or

          (n)  Aside from any actions contemplated by this Agreement, take or
     permit any action relating to NexGen which would prevent the Merger from
     qualifying for pooling-of-interests accounting treatment in accordance with
     Generally Accepted Accounting Principles and all rules, regulations and
     policies of the SEC.

     4.2  Affirmative Covenants.  Prior to or on the Effective Time NexGen will
          ---------------------                                                
do each of the following:

          (a)  Use its best efforts to perform and fulfill all conditions and
     obligations on its part to be performed and fulfilled under this Agreement
     to the end that the

                                       37

<PAGE>
 
     transactions contemplated by this Agreement shall be fully carried out;

          (b)  Use its best efforts to obtain all authorizations, consents and
     permits of others required to permit the consummation by NexGen of the
     transactions contemplated by this Agreement and the Credit Agreement and
     the continuation of NexGen's business after consummation of the Merger,
     including, without limitation, using its best efforts through preparation,
     SEC clearance and distribution as promptly as possible of the Proxy
     Statement (as defined below) and otherwise to obtain the approval of
     NexGen's stockholders sufficient for corporate and tax law purposes and
     pooling-of-interests accounting;

          (c)  Cooperate with AMD to the best of NexGen's ability in the
     preparation of (i) the joint proxy statement to be used in connection with
     the solicitation of proxies from the respective stockholders of AMD and
     NexGen with respect to approval of the Merger (the "Proxy Statement"); (ii)
     the S-4; and (iii) the S-8 (as defined below).  (Collectively, the S-4 and
     S-8 are referred to herein as the "Registration Statements.") In this
     regard, NexGen from time to time will furnish to AMD, and be responsible
     for, all information regarding NexGen required for the proper preparation
     of such Proxy Statement and Registration Statements and shall promptly
     furnish AMD with information with respect to any event as a result of which
     the Registration Statements, if such information were not disclosed
     therein, would include an untrue statement of a material fact relating to
     NexGen or the NexGen Subsidiaries or omit a material fact necessary to make
     the statements therein relating to NexGen or the NexGen Subsidiaries not
     misleading;

          (d)  Promptly advise AMD in writing of (i) any materially adverse
     change in the financial condition, business, operations or key personnel of
     NexGen or the NexGen Subsidiaries; and (ii) the occurrence of any event
     which causes the representations and warranties made by NexGen in this
     Agreement or the information included in NexGen Disclosure Schedule to be
     incomplete or inaccurate in any material respect;

          (e)  Conduct its business only in the ordinary course and refrain from
     changing or introducing any method of management or operations except in
     the ordinary course of business and consistent with prior practices;

          (f)  Use its best efforts to keep intact its business organization to
     keep available its present officers, agents and employees as NexGen deems
     necessary or appropriate to continue its business as presently conducted
     and to preserve

                                       38

<PAGE>
 
     the goodwill of all suppliers, customers and others having business
     relations with it;

          (g)  Permit AMD and its authorized representatives to have full access
     to all of its properties, assets, records, tax returns, contracts and
     documents and furnish to AMD and its authorized representatives such
     financial and other information with respect to its business and properties
     as AMD may from time to time reasonably request for purposes of making a
     review of the business of NexGen, which review may include an environmental
     assessment;

          (h)  Except as expressly permitted by Section 4.3(d), use its best
     efforts to obtain approval of this Agreement by the holders of outstanding
     shares of NexGen Common Stock entitled to vote (and to that end, will
     recommend approval of the Merger to NexGen's stockholders) and present
     evidence of such recommendation and approval to AMD in form and content
     satisfactory to AMD and its counsel;

          (i)  As promptly as reasonably practicable after the date of this
     Agreement, file with the Federal Trade Commission and the Antitrust
     Division of the United States Department of Justice and any other
     governmental agencies or departments all notices, reports and other
     documents required by law with respect to this Agreement and the Merger and
     promptly submit any additional information or documentary material properly
     requested by any such governmental agency or department;

          (j)  In the event that between the date hereof and the Effective Time,
     any person, entity or federal, state, local or foreign governmental
     authority shall commence any examination, review, investigation, action,
     suit or proceeding against NexGen with respect to the Merger, NexGen shall
     give prompt notice thereof to AMD, shall keep AMD informed as to the status
     thereof, and shall (except as may be prohibited by such governmental
     authority or by any court order or decree in an action or suit instituted
     by a person other than NexGen or an affiliate of NexGen) permit AMD to
     observe and be present at each meeting, conference or other proceeding and
     have access to and be consulted in connection with any document filed or
     provided to such person, entity or governmental authority in connection
     with such examination, review, investigation, action, suit or proceeding;

          (k)  Deliver to AMD at the Closing the resignations of all directors
     of NexGen;

          (l)  Promptly provide AMD with (i) copies of all written materials and
     communications furnished by NexGen to

                                       39

     its stockholders after the date of this Agreement, and (ii) copies of all
     notices, reports or other documents filed with the Federal Trade Commission
     or the Antitrust Division of the United States Department of Justice

     related consolidated statements of income, changes in financial position
     and changes in stockholders' equity for all interim monthly and quarterly
     periods prior to the Closing.  Such monthly and quarterly financial
     statements shall be prepared in conformity with generally accepted
     accounting principles applied on a consistent basis (subject to the absence
     of footnotes) and shall present (subject to normal year-end audit
     adjustments) the consolidated financial condition, results of operations
     and changes in consolidated financial position of NexGen and the NexGen
     Subsidiaries as of the dates and for the periods covered by such
     statements;

          (n)  As of the Effective Time, employees of NexGen and its
     Subsidiaries shall cease to accrue any additional benefits under all NexGen
     Benefit Arrangements and Employee Benefit Plans and any other plans or
     agreements for the benefit of the employees of NexGen or its Subsidiaries,
     except under plans, arrangements or agreements which AMD has elected to
     continue, which election will be in the sole discretion of AMD. At the
     request of AMD, NexGen and the NexGen Subsidiaries will take such action as
     may be requested by AMD to enter into, amend, or terminate any or all of
     the NexGen Benefit Arrangements, Employee Benefit Plans and any other
     benefit plans or agreements in connection therewith, with such amendments
     or terminations to be effective as of the Effective Time;

     form of Exhibit C attached hereto, executed by NexGen's stockholders after
     the date on which a public announcement is made concerning the execution of
     this Agreement; and

          (q)  Promptly following the date of this Agreement, consider the
     adoption of a stockholders rights plan and adopt such a plan if the Board
     of Directors of NexGen concludes that such plan is in the best interests of
     NexGen and its stockholders.

     4.3  No Solicitation.
          --------------- 

          (a)  NexGen shall immediately cease and cause to be terminated any
     existing discussions or negotiations with regard to a business combination
     or similar transaction with any parties other than AMD and AMD Merger.
     NexGen agrees not to release any third party from any confidentiality or
     standstill agreement to which NexGen is a party.

          (b)  NexGen shall not, directly or indirectly, through any officer,
     director, employee, representative or agent of NexGen or any NexGen
     Subsidiaries, solicit or encourage (including by way of furnishing
     nonpublic information) the initiation of any inquiries or proposals
     regarding any merger, consolidation, sale of substantial assets, sale of
     shares of capital stock including without limitation by way of a tender
     offer or similar transactions involving NexGen or any NexGen Subsidiaries
     (any of the foregoing inquiries or proposals being referred to herein as an
     "Acquisition Proposal").  Notwithstanding the foregoing, if a corporation,
     partnership, person, or other entity or group (a "Third Party") after the
     date of this Agreement submits to the Board of Directors of NexGen an
     unsolicited bona fide, written Acquisition Proposal (i) which is not
     subject to any financing contingency, (ii) which the Board of Directors of
     NexGen determines may constitute a Superior Proposal (as that term is
     defined in Section 4.3(d) of this Agreement), and (iii) the Board of
     Directors of NexGen concludes, after receipt of advice from outside legal
     counsel to NexGen, that the failure to engage in discussions with the Third
     Party concerning such Acquisition Proposal would cause the Board of
     Directors to violate its fiduciary duties to NexGen and its stockholders,
     then in such case NexGen may (x) furnish information about its business,
     properties, or assets to the Third Party under protection of a
     confidentiality agreement substantially the same in its protections to
     NexGen as the Confidentiality and Standstill Agreement dated October 16,
     1995, between NexGen and AMD, and (y) negotiate and participate in
     discussions and negotiations with such Third Party.  Thereafter, if the
     Board of Directors of NexGen concludes, after receipt of advice from
     outside legal counsel to NexGen, that it is under a duty to take actions
     reasonably calculated to maximize present stockholder value, the Board of
     Directors may approve the solicitation of additional Acquisition Proposals
     and furnish such information and have such negotiations as it deems
     advisable under the circumstances.

          (c)  NexGen shall immediately notify AMD after receipt of any
     Acquisition Proposal or any request for nonpublic information relating to
     NexGen or any NexGen Subsidiaries in connection with an Acquisition
     Proposal or for access to the

                                       41

<PAGE>
 
     properties, books or records of NexGen or any subsidiary by any person or
     entity that informs the Board of Directors of NexGen or such NexGen
     Subsidiary that it is considering making, or has made, an Acquisition
     Proposal.  Such notice to AMD shall be made orally and in writing and shall
     include a copy of any writing submitted by such person or entity and shall
     indicate in reasonable detail the identity of the offeror and the terms and
     conditions of such proposal, inquiry or contact.

          (d)  Notwithstanding the foregoing, in the event the Board of
     Directors of NexGen receives an Acquisition Proposal that based on the
     advice of outside counsel, the Board of Directors is required to consider
     in the exercise of its fiduciary obligations and that it determines to be a
     Superior Proposal, the Board of Directors may (subject to the following
     sentences) withdraw or adversely modify its approval or recommendation of
     the Merger and recommend any such Superior Proposal, or terminate the
     Agreement but such termination may occur only after the NexGen
     Stockholders' Meeting, in each case at any time after the fourth business
     day following delivery of written notice to AMD (a "Notice of Superior
     Proposal") advising AMD that the Board of Directors has received a Superior
     Proposal, specifying the material terms of the structure of such Superior
     Proposal. NexGen may take any of the foregoing actions pursuant to the
     preceding sentence only if an Acquisition Proposal that was a Superior
     Proposal continues to be a Superior Proposal in light of any improved
     transaction proposed by AMD prior to the expiration of the four business
     day period specified in the preceding sentence. For purposes of this
     Agreement, a "Superior Proposal" means any bona fide Acquisition Proposal
     to merge with NexGen or to acquire, directly or indirectly, a material
     equity interest in or a significant amount of voting securities or assets
     of NexGen for consideration consisting of cash and/or securities, and
     otherwise on terms which the Board of Directors of NexGen determines in the
     proper exercise of its fiduciary duties (based on the advice of a financial
     advisor of nationally recognized reputation including, without limitation,
     PaineWebber Incorporated) to provide greater value to NexGen and its
     stockholders than the Merger (or otherwise proposed by AMD as contemplated
     above). Nothing contained herein shall prohibit NexGen from taking and
     disclosing to its stockholders a position contemplated by Rule 14d-9(e)
     under the Exchange Act prior to the fourth business day following
     Purchaser's receipt of a Notice of Superior Proposal provided that NexGen
     does not withdraw or modify its position with respect to the Merger or
     approve or recommend an Acquisition Proposal.

          (e)  NexGen agrees to use its best efforts to ensure

                                       42

     in the fiscal year ended December 25, 1994;

          (c)  Undertake any consolidation or merger of AMD with or into another
     corporation other than a merger with another corporation in which AMD is a

     merger, to the extent reasonably deemed necessary by NexGen, AMD or the
     successor corporation shall execute appropriate documentation to insure the
     result provided for in Section 1.5(b).

          (d)  Aside from any actions contemplated by this Agreement, take or

     regulations and policies of the SEC, and AMD will use its

     best efforts to prevent any of its officers or directors from taking or
     permitting any such action;

     constitute an unauthorized "prospectus" within the meaning of the
     Securities Act;

          (h)  Issue any press release or any public disclosure, either written
     or oral, of the transactions contemplated by this Agreement or negotiations
     related thereto without the prior knowledge and written consent of NexGen,
     which consent shall not be unreasonably withheld; provided, however, that
     no such consent shall be required if AMD has determined in good faith upon
     written advice of counsel that it is required under applicable securities
     laws to make the disclosure; or

          (i)  Violate the terms of the Credit Agreement.

     5.2  Affirmative Covenants.   Prior to or on the Effective Time AMD and/or

AMD Merger will do the following:

          (a)  Use its best efforts to perform and fulfill all conditions and
     obligations on their part to be performed and fulfilled under this
     Agreement, to the end that the transactions contemplated by this Agreement
     and the Credit Agreement shall be fully carried out;

          (b)  Use its best efforts to obtain all authorizations, consents and
     permits of others required to permit the consummation by AMD and AMD Merger
     of the transactions contemplated by this Agreement and the Credit
     Agreement, including, without limitation, using its best efforts through
     preparation, SEC clearance and distribution as promptly as possible of the

          (c)  Cooperate with NexGen to the best of AMD's ability in the
     preparation of the Proxy Statement;

          (d)  File the S-4 with the SEC as promptly as practicable, which shall

     shares of NexGen Common Stock will be converted on the Effective Time, and
     use its best efforts to cause the S-4 to become effective as soon after
     such filing as practicable.  In this regard, AMD

                                       44

<PAGE>
 
     will advise NexGen promptly as to the time at which the S-4 becomes
     effective and of the issuance by the SEC of any stop order suspending the
     effectiveness of the S-4 or the institution of any proceedings for such
     purpose and will use its best efforts to prevent the issuance of any stop
     order and to obtain as soon as possible the lifting thereof if issued.
     Until the Effective Time, AMD will advise NexGen promptly of any
     requirement of the SEC for any amendment or supplement to the S-4 or for
     additional information, and will not at any time file any amendment of or
     supplement to the prospectus contained therein (or to the prospectus filed
     pursuant to Rule 424(b) of the SEC) (the "Prospectus") which shall not have
     been previously submitted to NexGen a reasonable time prior to the proposed
     filing thereof or to which NexGen shall reasonably object or which is not
     in compliance in all material respects with the Securities Act and the
     rules and regulations issued by the SEC thereunder.  When the S-4 becomes
     effective, it will comply in all material respects with the provisions of
     the Securities Act and the rules and regulations thereunder.  From and
     after the date the S-4 becomes effective and until the Effective Time, if
     any event occurs as a result of which the Prospectus would include an
     untrue statement of a material fact or omit to state a material fact
     necessary to make the statements therein not misleading or if it is
     necessary at any time to amend the S-4 or the Prospectus to comply with the
     Securities Act, AMD will promptly notify NexGen and will prepare an amended
     or supplemented S-4 or Prospectus which will correct such statement or
     omission and will use its best efforts to cause any such amendment to
     become effective as promptly as possible.  AMD will deliver to NexGen two
     signed copies of the S-4 and all amendments thereto, including all
     financial statements and exhibits filed therewith;

          (e)  If any shares of AMD Common Stock are listed on the NYSE or any
     other exchange as of the Closing Date, use its best efforts to list the AMD
     Common Stock to be issued pursuant to the Merger on the NYSE or such other
     exchange;

          (f)  Promptly advise NexGen in writing of (i) any materially adverse
     change in the financial condition, business, operations or key personnel of
     AMD or the AMD Subsidiaries; and (ii) the occurrence of any event which
     causes the representations and warranties made by AMD in this Agreement or
     the information included in AMD Disclosure Schedule to be incomplete or
     inaccurate in any material respect;

          (g)  Provide to NexGen such financial reports and other information as
     may be reasonably requested by NexGen for the purpose of monitoring the
     business of AMD;

<PAGE>
 
          (h)  Use its best efforts to (i) qualify the Common Stock to be issued
     pursuant to the Merger under the securities or "blue sky" laws of every
     jurisdiction of the United States in which any registered stockholder of
     NexGen has an address on the records of NexGen's transfer agent on the
     record date for determining the NexGen stockholders entitled to notice of
     and to vote on the Merger, and (ii) qualify the NexGen Options and NexGen
     Warrants to be assumed by AMD pursuant to Section 5.3 under the securities
     or "blue sky" laws or every jurisdiction of the United States in which the
     records of NexGen, as of the Closing Date, indicate that a holder of such
     options or warrants resides, except in either case any such jurisdiction
     with respect to which counsel for AMD has determined that such
     qualification is not required under the securities or "blue sky" laws of
     such jurisdiction;

          (i)  Use its best efforts to obtain the approval of this Agreement by
     affirmative vote of the holders of the outstanding shares of AMD Common
     Stock entitled to vote (and to that end, will recommend approval of the
     Merger to AMD's stockholders) and shall present evidence of such
     recommendation and approval to NexGen in form and content satisfactory to
     NexGen and its counsel;

          (j)  As promptly as reasonably practicable after the date of this
     Agreement, file with the Federal Trade Commission and the Antitrust
     Division of the United States Department of Justice and any other
     governmental agencies or departments all notices, reports and other
     documents required by law with respect to this Agreement and the Merger and
     promptly submit any additional information or documentary material properly
     requested by any such governmental agency;

          (k)  In the event that between the date hereof and the Effective Time,
     any person, entity or federal, state, local or foreign governmental
     authority shall commence any examination, review, investigation, action,
     suit or proceeding against AMD with respect to the Merger, AMD shall give
     prompt notice thereof to NexGen, shall keep NexGen informed as to the
     status thereof, and shall (except as may be prohibited by such governmental
     authority or by any court order or decree in an action or suit instituted
     by a person other than AMD or an affiliate of AMD) permit NexGen to observe
     and be present at each meeting, conference or other proceeding and have
     access to and be consulted in connection with any document filed or
     provided to such person, entity or governmental authority in connection
     with such examination, review, investigation, action, suit or proceeding;

                                       46

<PAGE>
 
          (l)  Cause AMD Merger to perform all of its agreements contained
     herein and in the Merger Agreement;

          (m)  Promptly provide NexGen with (i) copies of all written materials
     and communications furnished by AMD to its stockholders after the date of
     this Agreement, and (ii) copies of notices, reports or other documents
     filed with the Federal Trade Commission or the Antitrust Division of the
     United States Justice Department pursuant to Section 5.2(j) hereof (iii)
     copies of all reports filed with the SEC;

          (n)  Promptly provide NexGen copies of its Consolidated Balance Sheet
     and related consolidated statements of income, changes in financial
     position and changes in stockholders' equity for all interim 4-week and
     quarterly periods prior to the Closing.  Such 4-week and quarterly
     financial statements shall be prepared in conformity with Generally
     Accepted Accounting Principals applied on a consistent basis (subject to
     the absence of footnotes) and shall present (subject to normal year-end
     audit adjustments) the consolidated financial condition, results of
     operations and changes in financial position of AMD and the AMD
     Subsidiaries as of the dates and for the periods covered by such
     statements;

          (a)  At the Effective Time, AMD shall assume the NexGen 1987 Stock
     Plan, the NexGen 1995 Stock Plan and the NexGen 1995 Employee Stock
     Purchase Plan; and each NexGen Option then outstanding under such plans
     shall remain outstanding and shall be deemed an option to purchase, in
     place of the purchase of NexGen Common Stock previously subject to such
     option, that number of shares of AMD Common Stock equal to the product of
     the number of shares subject to the NexGen Option, to the extent not
     exercised or terminated on or prior to the Effective Time, multiplied by
     the Exchange Ratio and rounded downward to the nearest whole share, at an
     exercise price per share equal to the exercise price per share under the
     NexGen Option divided by the Exchange Ratio and rounded upward to the
     nearest whole cent.  The assumption of the NexGen Options which are
     incentive stock options as defined in Section 422(b) of the Code and of
     options outstanding under the NexGen Employee Stock Purchase Plan shall be
     accomplished in a transaction to which Section 424(a) of the Code applies.
     All the other terms and

                                       47

     conditions of the NexGen Options shall remain the same.

          (b)  As of the Effective Time, each NexGen Warrant then outstanding
     shall remain outstanding and shall be deemed to be a warrant to purchase,
     in place of the purchase of the shares of NexGen Common Stock previously
     subject to such Warrant, that number of shares of AMD Common Stock equal to
     the product of the number of shares of NexGen Common Stock subject to such
     Warrant, and not exercised prior to the Effective Time, multiplied by the
     Exchange Ratio and rounded downward to the nearest whole share.  The
     exercise price per share shall be equal to the exercise price per share
     under the NexGen Warrant divided by the Exchange Ratio and rounded upward
     to the nearest one-hundredth of one (1) whole cent.  As of the Effective
     Time, any existing right of ASCII Corporation to convert debt payable by
     NexGen into NexGen Common Stock shall remain effective and shall be deemed
     to be a right to convert such debt into that number of shares of AMD Common
     Stock as is equal to the product of the number of shares of NexGen Common
     Stock into which such debt could have been converted prior to the Effective
     Time, and was not so converted, multiplied by the Exchange Ratio and
     rounded downward to the nearest whole share.

          (c)  AMD will (i) file with the SEC a new registration statement on
     Form S-8 relating to such NexGen Options and the shares of AMD Common Stock
     to be issued upon their exercise or an amendment to its existing
     registration statement on Form S-8 to include such options and shares (such
     new or amended registration statement is referred to in this Agreement as
     the "S-8"), (ii) file with the SEC a registration statement on Form S-3 (or
     such other form as AMD deems appropriate) (the "S-3") relating to such
     NexGen Warrants and the shares of AMD Common Stock to be issued upon their
     exercise, (iii) use its best efforts to cause the S-8 and the S-3 to become
     effective prior to the Closing, and (iv) if the shares of AMD Common Stock
     issuable upon exercise of existing AMD stock option plans are listed on the
     NYSE or some other exchange as of the Closing Date, AMD will list the
     shares of AMD Common Stock to be issued pursuant to NexGen Options and
     NexGen Warrants assumed by AMD on the NYSE or such other exchange.

     5.4  Employee Benefits.  Consistent with AMD's employee benefit plans, all
          -----------------                                                    
NexGen employees who become employees of AMD or a subsidiary of AMD as of the
Effective Time shall receive the same or reasonably comparable benefits as such
NexGen employees currently receive and, to the extent not prohibited by law,
shall receive service credit which includes their employment by NexGen prior to
the Effective Time.

          -------------------------                                 
AMD and the AMD Subsidiaries and each of their officers, directors, employees
and agents from and against any and all losses, claims, damages or liabilities
(including expenses), joint and several, to which any of them may become subject
under the Securities Act, the Exchange Act, common law, or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of, or are based upon, any untrue statement or alleged untrue
statement of any material fact contained in the S-4, the Prospectus or the Proxy
Statement or arise out of, or based upon, the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse each such party to be
indemnified by it for any legal or other expenses reasonably incurred by such
party in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the foregoing
indemnification shall be limited to any loss, claim, damage or liability
(including expenses) arising out of, or based upon, any untrue statement or
alleged untrue statement in or omission or alleged omission from the S-4, the
Prospectus or the Proxy Statement made in reliance upon and in conformity with
information furnished by or on behalf of NexGen or any of the NexGen
Subsidiaries specifically for use therein or in preparation thereof. The
indemnity agreement in this section is in addition to any liability which NexGen
may otherwise have.

     6.2  Indemnification by AMD.  AMD will indemnify and hold harmless NexGen
          ----------------------                                       
and the NexGen Subsidiaries and each of their officers, directors, employees and
agents from and against any and all losses, claims, damages or liabilities
(including expenses), joint or several, to which any of them may become subject
under the Securities Act, the Exchange Act, common law or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of, or are based upon, any untrue statement or alleged untrue
statement of any material fact contained in the S-4, the Prospectus or the Proxy
Statement or arise out of, or are based upon, the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse each such party
to be indemnified by it for any legal or other expenses reasonably incurred by
such party in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that there shall be excluded
from the foregoing indemnification any loss, claim, damage or liability
(including expenses) arising out of, or based upon, any untrue statement or
alleged untrue statement in or omission or alleged omission from the S-4, the

                                       49

<PAGE>
 
Prospectus or the Proxy Statement made in reliance upon and in conformity with
information furnished by or on behalf of NexGen or any NexGen Subsidiary
specifically for use therein or in preparation thereof.  The indemnity agreement
in this section is in addition to any liability which AMD may otherwise have.

     6.3  Defense of Action.  Promptly after receipt by an indemnified person
          -----------------                                           
under this Section 6 of notice of the commencement of any action, such
indemnified person shall, if a claim in respect thereof is to be made against
the indemnifying party under this Section 6, notify the indemnifying party in
writing of the commencement thereof, enclosing a copy of all papers served. The
failure to notify the indemnifying party shall relieve it from any liability
under this Section 6, but not from any liability the indemnifying party might
otherwise have to the indemnified party. The party proposing to be indemnified
shall cooperate fully with the indemnifying party in the defense of the action.
If the indemnifying party agrees in writing to assume and undertake the defense
of the claim or action, the indemnifying party shall have the right to select
and retain counsel reasonably satisfactory to the indemnified person and the
indemnified person, upon receipt of written notice of the agreement of the
indemnifying party, shall have no right to indemnification of fees or expenses
incurred subsequent to receipt of the notice. If, however, the indemnified party
requires separate counsel because a conflict of interest would otherwise exist,
the indemnifying party shall pay the reasonable legal fees and reasonable
expenses of such separate counsel on a monthly basis. The identifying party
shall not be liable for any settlement or compromise effected without its
consent. The indemnifying party shall have the right to settle or otherwise
compromise the action in its sole discretion provided that it agrees to satisfy
any and all settlement obligations from its own resources.

     6.4  Additional Indemnification by AMD.  AMD agrees that upon consummation
          ---------------------------------                       
of the Merger and at all times thereafter, AMD shall indemnify and hold harmless
each person who was an officer or director of NexGen prior to the Effective Time
upon the same terms and conditions as each such person was entitled to be
indemnified by NexGen at the date hereof and as of the Effective Time pursuant
to the Bylaws of NexGen or any agreement between NexGen and each such person or
as provided by the DGCL.

shall have been no material adverse change in the business or financial
condition of NexGen and the NexGen Subsidiaries taken as a whole. For the
purposes hereof, a material adverse change shall mean a material adverse change,
other than a decrease in the reported stock price, which (from the perspective
of AMD) results in a significant diminution of the value of the NexGen business
enterprise as a whole, and which material adverse change shall cause Donaldson,
Lufkin & Jenrette Securities Corporation to withdraw its written opinion to the
Board of Directors or AMD delivered pursuant to Section 8.5 hereof.

     8.3  Section 2.23 Documents. AMD shall have received the Section 2.23

Effective Time with the employment arrangements between NexGen and (i) those
employees of NexGen whom AMD has identified to NexGen as key employees and (ii)
any additional employees of NexGen whom AMD reasonably identifies as key
employees to the business of NexGen as now being conducted or currently proposed
to be conducted prior to the Effective Time.

     8.5  Fairness Opinion.  The Board of Directors of AMD shall have received a
          ----------------                                           
written opinion from Donaldson, Lufkin and

                                       52

<PAGE>
 
Jenrette Securities Corporation, dated the date of this Agreement and dated on
the date on which the Proxy Statement is first mailed to AMD stockholders, in
form and substance satisfactory to AMD, stating that the consideration to be
paid by AMD in the Merger is fair to the stockholders of AMD from a financial
point of view and such opinion shall not have been withdrawn by the closing.

     8.6  Comfort Letter.  AMD shall have received a letter from Price
          --------------                                              
Waterhouse LLP, as independent certified public accountants for NexGen, dated
(i) the effective date of the S-4, and (ii) the Closing Date, in each case
substantially to the effect that:  

          (a)  it is a firm of independent public accountants with respect to
     NexGen and its Subsidiaries within the meaning of the Securities Act and
     the rules and regulations of the SEC thereunder;

          (b)  in its opinion, the audited consolidated financial statements of
     NexGen and its Subsidiaries examined by it and included or incorporated by
     reference in the S-4 comply as to form in all material respects with the
     applicable requirements of the Securities Act and the Exchange Act and the
     applicable published rules and regulations of the SEC thereunder with
     respect to registration statements on Form S-4; and

          (c)  on the basis of specified procedures (which do not constitute an
     examination in accordance with generally accepted auditing standards),
     consisting of a reading of the unaudited consolidated financial statements
     of NexGen and its subsidiaries included or incorporated by reference in the
     S-4 and of the latest available unaudited consolidated financial statements
     of NexGen and its Subsidiaries, inquiries of officers of NexGen and its
     Subsidiaries responsible for financial and accounting matters, and a
     reading of the minutes of meetings of stockholders and the Board of
     Directors of NexGen and its Subsidiaries, nothing has come to its attention
     which causes it to believe: (1) that the unaudited consolidated financial
     statements of NexGen and its Subsidiaries included or incorporated by
     reference in the S-4 do not comply as to form in all material respects with
     the applicable accounting requirements of the Securities Act and the
     published rules and regulations thereunder, (2) that the unaudited
     consolidated financial statements are not fairly presented in conformity
     with generally accepted accounting principles consistently applied and on a
     basis substantially consistent with that of the audited consolidated
     financial statements, or (3) that as of a date which is five (5) business
     days prior to the date of such letter there was any change in the capital
     stock, any increase in long-term debt or any

                                       53

<PAGE>
 
     decrease in consolidated net assets of NexGen and its Subsidiaries as
     compared to the amounts shown in the NexGen Audited Balance Sheet, or that
     during the period from June 30, 1995, to the most recent month-end for
     which financial statements are available there was any decrease, as
     compared with the corresponding period in the preceding year, in
     consolidated net income of NexGen and its Subsidiaries, except in all
     instances for changes or decreases which are set forth in such letter or
     which the S-4 discloses have occurred or may occur;

and covering such other matters (including tables, statistics and other
financial information and data included in the S-4) as AMD may reasonably
request consistent with the Statement on Auditing Standards No. 49 issued by the
American Institute of Certified Public Accountants.

     8.7  Legal Opinion.  AMD shall have received an opinion of Pillsbury,
          -------------                                                   
Madison & Sutro, counsel to NexGen, dated the Closing Date, in substantially the
form attached hereto as Exhibit D.

     8.8  Resignations.  AMD shall have received written resignations, effective
          ------------                                                          
as of the Closing Date, of each director of NexGen.

Bronson & McKinnon, counsel for AMD, in form and substance reasonably
satisfactory to it and substantially identical in form and substance to the
opinion described in Section 9.3 of this Agreement to the effect that the Merger
will constitute a reorganization within the meaning of Section 368(a)(1) of the
Code.  Counsel shall, in rendering such opinion, be entitled to rely on
representations of AMD, AMD Merger and NexGen.

     8.10 Pooling-of-Interests Accounting Treatment.  AMD shall have received a
          -----------------------------------------                            
letter from Ernst & Young LLP, AMD's independent public accountants, dated the
Closing Date, in form and substance satisfactory to AMD, to the effect that the
Merger will qualify for pooling-of-interests accounting treatment in accordance
with generally accepted accounting principles and all applicable rules,
regulations and policies of the SEC and the NYSE.

shall have been no material adverse change in the business or financial
condition of AMD and the AMD Subsidiaries taken as a whole.  For the purposes
hereof, a material adverse change shall mean a material adverse change, other

NexGen) results in a significant diminution of the value of the AMD business
enterprise as a whole, and which material adverse change shall cause PaineWebber
Incorporated to withdraw its written opinion to the Board of Directors of NexGen

received a written opinion from PaineWebber Incorporated dated the date of this
Agreement and updated on the date on which the Proxy Statement is first mailed

     10.1  Termination.  This Agreement may be terminated at any time prior to
           -----------                                                        
the Effective Time, notwithstanding approval thereof by the shareholders either
of AMD or of NexGen or of both:

          (a)  by mutual written consent duly authorized by the Boards of
     Directors of AMD and NexGen; or

          (b)  by either AMD or NexGen if the Merger shall not have been
     consummated by June 30, 1996, provided, however, that the right to
     terminate this Agreement under this Section 10.1(b) shall not be available
     to any party whose failure to fulfill any obligation under this Agreement
     has been the cause of or resulted in the failure of the Merger to occur on
     or before such date; or

          (c)  by either AMD or NexGen if a court of competent jurisdiction or
     governmental, regulatory or administrative agency or commission shall have
     issued an order, decree or ruling or taken any other action, in each case
     having the effect of permanently restraining, enjoining or otherwise
     prohibiting the Merger; or

          (d)  by AMD or NexGen, if (i) at the NexGen Stockholders' Meeting
     (including any adjournment or postponement thereof), the requisite vote of
     the stockholders of NexGen shall not have been obtained and (ii) in the
     case of the termination of this Agreement under this Section 10.1(d) by
     NexGen, NexGen shall have paid to AMD all amounts owing by NexGen to AMD
     under Section 10.3; or

          (e)  By AMD or NexGen, if (i) at the AMD Stockholders' Meeting
     (including any adjournment or postponement thereof), the requisite vote of
     the stockholders of AMD shall not have been obtained and (ii) in the case
     of the termination of this Agreement under this Section 10.1(e) by AMD, AMD
     shall have paid to NexGen all amounts owing by AMD to NexGen under Section
     10.3; or

          (f)  by AMD, if a tender offer or exchange offer for 20% or more of
     the outstanding shares of NexGen Common Stock is commenced (other than by
     AMD or an affiliate of AMD), and within ten (10) business days of such
     commencement the Board of Directors of NexGen shall not have recommended
     that the shareholders of NexGen not tender their shares in such tender or
     exchange offer; or

          (g)  by NexGen, upon a breach of any representation, warranty,
     covenant or agreement on the part of AMD set forth in this Agreement, or if
     any representation or warranty of AMD shall have become untrue, in either
     case such that the

                                       56

<PAGE>
 
     conditions set forth in Section 9.1 would not be satisfied (a "Terminating
     AMD Breach"), provided, that, if (i) such Terminating AMD Breach is curable
     by AMD through the exercise of its reasonable best efforts and for so long
     as AMD continues to exercise such reasonable best efforts, or (ii) such
     Terminating AMD Breach relates solely to representations and warranties and
     does not cause PaineWebber Incorporated to withdraw its written opinion to
     the Board of Directors of NexGen delivered pursuant to Section 9.4 hereof;
     then NexGen may not terminate this Agreement under this Section 10.1(g); or

          (h)  by AMD, upon breach of any representation, warranty, covenant or
     agreement on the part of NexGen set forth in this Agreement, or if any
     representation or warranty of NexGen shall have become untrue, in either
     case such that the conditions set forth in Section 8.1 would not be
     satisfied ("Terminating NexGen Breach"), provided, that, (i) if such
     Terminating NexGen Breach is curable by NexGen through the exercise of its
     reasonable best efforts and for so long as NexGen continues to exercise
     such reasonable best efforts, or (ii) such Terminating NexGen Breach
     relates solely to representations and warranties and does not cause
     Donaldson, Lufkin & Jenrette Securities Corporation to withdraw its written
     opinion to the Board of Directors of AMD delivered pursuant to Section 8.5
     hereof; then AMD may not terminate this Agreement under this Section
     10.1(h).

     10.2  Effect of Termination.  If this Agreement shall be terminated as
           ---------------------                                           
provided in Section 10.1, this Agreement shall forthwith become void (except as

the part of any party hereto to any other party except for (i) payment of any
amounts payable pursuant to Section 10.3, (ii) payment of any amounts payable
pursuant to Section 11.4 and (iii) any damages for a material breach of this

representation, warranty or covenant in this Agreement.

     10.3 Fees and Expenses.
          ----------------- 

          (a)  Except as set forth in this Section 10.3, all fees and expenses
     incurred in connection with this Agreement and the transactions
     contemplated hereby shall be paid by the party incurring such expenses,
     whether nor not the Merger is consummated; provided, however, that AMD and
     NexGen shall share equally all fees and expenses other than attorneys'

     Statement (including any preliminary materials related thereto) and the
     Registration Statement (including financial statements and exhibits) and

     of the following events:

               (i)   if NexGen's Board of Directors prior to the vote at the
          NexGen Stockholders' Meeting has withdrawn, modified or changed in any
          manner adverse to AMD its recommendation of the Merger or resolved to
          do so, provided, however, that disclosing to its stockholders in
          conformance with the securities laws information regarding a Superior
          Alternative Transaction without so withdrawing, changing or modifying
          its recommendation shall not be deemed to be a breach of this clause
          (i); or

               (ii)  the NexGen Board prior to the vote at the NexGen
          Stockholders' Meeting has resolved to accept, accepted or recommended
          to the stockholders of NexGen a Superior Alternative Transaction; or

               (iii) the later to occur of both (A) the entering into an
          agreement contemplating a Superior Alternative Transaction or the
          consummation of a Superior Alternative Transaction on or before June
          30, 1996 and (B) termination of this Agreement pursuant to Sections
          (f) or (h) of Section 10.1 of this Agreement; or

               (iv)  the later to occur of both (A) the entering into an
          agreement contemplating an Alternative Transaction or the consummation
          of an Alternative Transaction on or before June 30, 1996 and (B)
          termination of this Agreement pursuant to Section 10.1(d); or


               (v)   as a result of any material breach by NexGen of Section 4.3
          of this Agreement as a result of any willful solicitation by NexGen's
          directors, executive officers, five other key employees identified by
          AMD in connection with Section 8.4(i), the financial advisor or
          counsel of NexGen;

     provided, however, that no payment hereunder shall be due with respect to
     any of such events which occurs after the earlier of June 30, 1996 or the
     termination of the Agreement by AMD and NexGen pursuant to Sections
     10.1(a), or by NexGen pursuant to section 10.1(b), 10.1(c), 10.1(e) or
     10.1(g).

          (c)  As used herein "Alternative Transaction" means: (i) a transaction

     AMD or its affiliates (a "Third Party") acquires more than 20% of the
     outstanding shares of NexGen Common Stock, whether from NexGen or pursuant
     to a tender offer or exchange offer or otherwise, provided, however, that
     after termination of this Agreement, the issuance of new equity by NexGen
     where reasonably necessary to provide continued funding for NexGen's
     operations shall not be deemed an Alternative Transaction except as
     provided in clause (iii) of this paragraph (c); (ii) a merger or other
     business combination involving NexGen pursuant to which any Third Party
     acquires more than 20% of the outstanding equity securities of NexGen or
     the entity surviving such merger or business combination; or (iii) any
     other transaction pursuant to which any Third Party acquires control of
     assets (including for this purpose the outstanding equity securities of
     subsidiaries of NexGen, and the entity surviving any merger or business
     combination including any of them) of NexGen or any of the NexGen
     Subsidiaries having a fair market value (as determined by the Board of
     Directors of NexGen in good faith) equal to more than 20% of the fair
     market value of all the assets of NexGen, and the NexGen Subsidiaries,
     taken as a whole, immediately prior to such transaction.  As used herein, a
     "Superior Alternative Transaction" means an Alternative Transaction in
     which consideration is received by NexGen or its stockholders for NexGen
     Common Stock and the consideration for each share of NexGen Common Stock
     has a greater value than the consideration for each share of NexGen Common
     Stock determined as of the date hereof to be received by Stockholders of
     NexGen pursuant to the Merger.

          (d)  If the Fee is payable pursuant to Section 10.3(b), then the Fee

     payment is earlier due as provided in Section 10.1(d).

          (e)  NexGen shall pay AMD $15,000,000 upon the earliest to occur of
     the following events: (i) the termination of this Agreement by AMD pursuant
     to Section 10.1(d) as a result of the failure to receive the requisite vote
     for approval of this Agreement and the Merger by the stockholders of NexGen
     at the NexGen Stockholders' Meeting; or (ii) the termination of this
     Agreement by AMD pursuant to Section 10.1(f).

          (f)  AMD shall pay NexGen $15,000,000 upon the termination of this
     Agreement by NexGen pursuant to Section 10.1(e) as a result of the failure
     to receive the requisite vote for approval of this Agreement and the Merger
     by the stockholders of AMD at the AMD Stockholders' meeting.

    otherwise:  (i) to repurchase such indebtedness; or (ii) to purchase, sell
    or lease (whether as lessee or lessor) property, products, materials or
    supplies, or to purchase or sell services, primarily for the purpose of
    enabling the debtor to make payment of such indebtedness or to assure the
    owner of the indebtedness against loss; or (iii) to supply funds to or in
    any other manner invest in the debtor; and

          "Index Base Rate" shall mean, for any day, a rate per annum (rounded

          "Index Rate" shall mean that rate established and published from time

its costs of funds and desired return, general economic conditions and other
factors.  BofA uses the Index Rate as a benchmark for pricing certain types of
loans.  Depending upon the circumstances, such as the amount and terms of a
loan, the creditworthiness of a borrower or any guarantor, the presence and
nature of collateral and other relationships between a borrower and BofA, loans
may be priced at, above or below the Index Rate.  The Borrower acknowledges that
the use of the appellation "Index Rate" does not constitute a representation on
the part of the Lender that no loans or for-bearances are made by BofA (or the
Lender) at a lesser rate of interest.  In the event that BofA shall cease to
establish or publish an Index Rate, whether denominated as such or otherwise,
the Index Rate shall be deemed to be the average "prime," "base" or "reference"
interest rate for each calendar month, as of the first day of such calendar
month, of the three largest (as determined by total assets) banking institutions
in the State of California (other than BofA) then establishing or publishing a
"prime," "base" or "reference" rate of interest; provided, however, that in the

so published by it.

    2.6   Interest Rate and Payments of Interest.
          -------------------------------------- 

          a.  Interest Rate.  All Advances shall bear interest as follows:
              -------------                                               

              (i)  Each Advance shall bear interest at a rate per annum equal
          to the Index Base Rate, computed on the basis of the actual number of
          days elapsed over a year of 365 or 366 days (as the case may be).
          Interest on each Advance shall be due and payable on the Maturity
          Date. The Lender shall determine and advise the Borrower three (3)
          Business Days prior to the Maturity Date of the total interest then

          Borrower, absent manifest error.

             (ii)  Interest on each Advance shall accrue from and including
          the date on which such Advance is made and to but excluding the date
          on which such Advance is repaid in full, unless the date of repayment

          such date shall be included.

          b.  Interest on Overdue Amounts; Alternative Rate of Interest.
              ---------------------------------------------------------  
    Notwithstanding any provision of this Section 2.6 to the contrary, if the
    Borrower shall default in the payment of the principal of or interest on any
    Advance or any fees or other amounts becoming due hereunder, whether by
    scheduled maturity, notice of prepayment, acceleration or otherwise, the
    Borrower shall on demand from time to time from the Lender pay interest from
    and including the date of such default, to the extent permitted by law, on
    such defaulted amount up to (but not including) the date of actual payment
    (after as well as before judgment) at a rate per annum (computed as provided
    in paragraph (a) of this Section 2.6) equal to the Index Base Rate plus two
    percent (2.00%).

          c.  Usury Law.  It is the intent of the Lender and the Borrower in
              ---------                                                     
    the execution of this Agreement, the Note and the

                                       9

<PAGE>
 
    Collateral Agreements and all other security agreements and financing
    statements evidencing the Borrower's obligations hereunder, to contract in
    strict compliance with the usury laws of the State of California (the "Usury
    Law").  In furtherance thereof, the Lender and the Borrower stipulate and
    agree that none of the terms and provisions contained herein or in the Note
    or in any Collateral Agreement or in any other instrument executed in
    connection herewith or therewith, shall ever be construed to create a
    contract to pay for the use, forbearance or detention of money at a rate of
    interest in excess of the maximum interest rate permitted to be charged by
    the Lender in compliance with the Usury Law.  Neither the Borrower nor any
    guarantors, endorsers or other parties now or hereafter becoming liable for
    payment hereunder or under the Note or any Collateral Agreement shall ever
    be required to pay interest thereon at a rate in excess of the maximum
    interest that may be lawfully charged by the Lender in compliance with the
    Usury Law, and the provisions of this paragraph 2.6(c) shall control over
    all other provisions hereof or of the Note or any Collateral Agreement, and
    of any other instruments now or hereafter executed in connection herewith or
    therewith, which may be in apparent conflict herewith.  If the maturity of
    any Obligations shall be accelerated for any reason or if the principal of
    the Note is paid prior to the expiration of the term thereof, and as a
    result thereof the interest received for the actual period of existence of
    the Loan exceeds the applicable maximum lawful rate permitted to be charged
    by the Lender in compliance with the Usury Law, the Lender shall refund to
    the Borrower the amount of such excess or shall, at its option, credit the
    amount of such excess against the principal balance of the Loan then
    outstanding.  In the event that the Lender shall collect monies which are
    deemed to constitute interest in excess of the lawful rate which the Lender
    may charge, for any reason whatsoever, such monies shall, upon such
    determination and at the option of the Lender, be immediately either
    returned to the Borrower or credited against the principal balance of the
    Loan then outstanding.

    2.7   Prepayments. The Borrower shall have the right to make payments in
          -----------                                                       
reduction of the outstanding balance of the Line of Credit, in whole or in part,
at any time; provided, however, that each such prepayment must be accompanied by
payment of all interest accrued thereon, and provided further that such
prepayment must be in the amount of One Million Dollars ($1,000,000) or integral
multiples thereof, or the outstanding balance if less.  Any amount of principal
so repaid may be reborrowed by Borrower and shall be available for future
Advances under the Line of Credit.

    2.8   Payment to the Lender.  All sums payable to the Lender hereunder
          ---------------------                                           
shall be paid directly to the Lender (or to a bank account specified by the
Lender) in immediately available funds.  The Lender shall send the Borrower
statements of all amounts due

                                       10

<PAGE>
 
hereunder, which statements shall be considered correct and conclusively binding
upon the Borrower (absent manifest error) unless the Borrower notifies the
Lender to the contrary within thirty (30) days of its receipt of any statement
which the Borrower believes to be incorrect.

    2.9   Other Secured Indebtedness.  The Borrower covenants and agrees with
          --------------------------                                         
the Lender that, so long as any of the Obligations shall remain outstanding, the
Borrower shall not, and shall not cause or permit any of the Subsidiaries to,
either directly or indirectly, create, incur, assume or permit to exist any
indebtedness secured by a Lien on any of its properties or assets, except for
Permitted Liens.  The Borrower also covenants and agrees to furnish to the
Lender promptly (and within any applicable cure period) notice of the occurrence
of an event of default or any event which with notice or the passage of time (or
both) would constitute an event of default under the Security Agreement dated
November 15, 1991, as amended, with ASCII Corporation and ASCII of America, Inc.
or the Security Agreement dated July 22, 1993 with Phemus Corporation.

    2.10  Subordination.  Lender agrees that the Obligations of Borrower
          -------------                                                 
hereunder, and the Liens granted to Lender pursuant to Article V hereof, are
subordinate to the prior payment in full of the indebtedness owing to ASCII
Corporation, ASCII of America, Inc. and Phemus Corporation (together the "Senior
Lenders") and junior in priority to the existing Liens in favor of the Senior
Lenders, as described in the security agreements referenced in Section 2.9
hereof, in each case whether such right of payment is in the ordinary course of
business or in the event of any distribution of the assets of Borrower upon any
dissolution, winding-up, liquidation or bankruptcy, insolvency or other similar
proceedings.  The Borrower will not make and the Lender will not demand, accept
or receive any payment on the Line of Credit or any Advances hereunder until all
amounts owing to the Senior Lenders shall have been paid in full.  The Lender
and the Borrower covenant to execute and deliver to the Senior Lenders such
further instruments and to take such further action as the Senior Lenders may at
any time or times reasonably request in order to carry out the provisions and
intent of this Section 2.10.

existing and in good standing under the laws of the State of Delaware, has the
corporate power to own its properties and to engage in the business it conducts,
and is duly qualified and in good standing as a foreign corporation in all
jurisdictions wherein the nature of the business transacted by it or property

knowledge of the Borrower, threatened against or affecting the Borrower or any
Subsidiary or the businesses, assets or rights of the Borrower or any Subsidiary

judgment, writ, injunction, decree, rule or regulation of any governmental
authority, where such violation or default could reasonably be expected to
result in a Material Adverse Effect.  Neither the Borrower nor any Subsidiary is
in default under any provision of any indenture or other agreement or instrument
evidencing Indebtedness, or any other material agreement or instrument to which
it is a party or by which it or any of its properties or assets are or may be
bound, where such default could reasonably be expected to result in a Material
Adverse Effect, and the entering into and performance by the Borrower of this

the expiration of an application cure period or the giving of notice, or both):
(i) violate any charter or bylaw provision of the Borrower or any Subsidiary, or

and marketable title to all of its respective assets, subject to no security
interest, encumbrance, Lien (except for Permitted Liens) or claim of any third
person.

present the financial condition of the Borrower and all of its Subsidiaries,
taken as a whole, at the dates thereof and the results of operations for the
periods covered thereby, and there has occurred no event which might reasonably
result in a Material Adverse Effect from the dates thereof to the date hereof.

conversion or exchange rights, commitments or agreements of any character
obligating any of the Subsidiaries to issue, deliver or sell additional shares

disclosed in the Financial Statements.

                    CONTENT OF OPINION OF BORROWER'S COUNSEL
                    ----------------------------------------



     The opinion of Pillsbury Madison & Sutro, counsel to the Borrower, shall
cover the matters set forth below.  All defined terms used herein and in the
opinion shall have the meaning ascribed to them in that certain Secured Credit
Agreement dated as of October 20, 1995, by and between Advanced Micro Devices,
Inc. and NexGen, Inc.

     1.   Each of the Borrower and its Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and each has the corporate power and authority to own its assets and
carry on its business as it is now being conducted.  Each of the Borrower and
its Subsidiaries is duly qualified to do business and is in good standing in all
jurisdictions in which the ownership of its property or the conduct of its
business makes such qualifications necessary.

     2.   The execution, delivery and performance of the Agreement, the Note and
the Collateral Documents by the Borrower are within the corporate power and
authority of the Borrower and have been duly authorized by all necessary
corporate action on the part of the Borrower.

     3.   The Agreement, the Note and the Collateral Documents have been duly
executed and delivered by the Borrower, and each constitutes the legal, valid
and binding obligations of the Borrower, enforceable against the Borrower in
accordance with their respective terms, except as the enforceability thereof may
be limited by bankruptcy, reorganization, insolvency, moratorium or other
similar laws affecting creditors' rights generally and by general equitable
principles regarding the availability of the remedy of specific performance.

     4.   All consents, authorizations, approvals of or filings or registrations
with any commission, board, agency, court or other
governmental authority necessary in connection with the valid
execution, delivery and performance of the Agreement, the Note and the
Collateral Documents by the Borrower have been obtained or effected and are in
full force and effect.

     5.   The execution and delivery by the Borrower of the Agreement, the Note
and the Collateral Documents as the case may be, will not:  (i) violate any
provision of the Certificate of

                                      E-1

<PAGE>
 
Incorporation or the Bylaws of the Borrower, or any law, rule or regulation
applicable to the Borrower, or any order, writ, judgment, decree, determination
or award known to us; (ii) to the best of our knowledge after due inquiry,
result in a breach of or constitute a default under any indenture, lease, loan
or other agreement or any instrument to which the Borrower or any Subsidiary is
a party or by which its respective properties may be bound or affected; or (iii)
to the best of our knowledge after due inquiry, result in, or require the
creation or imposition of, any Lien (other than in favor of the Lender) upon or
with respect to any of the properties now owned or hereafter acquired by the
Borrower or any Subsidiary.

     6.   To the best of our knowledge after due inquiry, the Borrower is not in
violation of any law, rule or regulation applicable to it or any order, writ,
judgment, decree, determination or award or any indenture, lease, loan or other
agreement to which it is a party or by which it or its properties may be bound
or affected, the violations of which could have a Material Adverse Effect upon
the ability of the Borrower to perform any of its obligations under the
Agreement, the Note and the Collateral Documents.

     7.   To the best of our knowledge, there are no actions, suits or
proceedings pending or threatened against the Borrower or any Subsidiary, or any
of its respective properties, before any court, arbitrator, commission, board,
agency or other authority which, if determined adversely to the Borrower or the
Subsidiary, could result in a Material Adverse Effect.

     8.   Neither the Borrower nor any Subsidiary is an "investment company"
within the meaning of the Investment Company Act of 1940, as amended, or a
"holding company" within the meaning of the Public Utility Holding Company Act
of 1935.

     9.   Upon the filing of the UCC-1 Financing Statement with the California
Secretary of State, the security interest of the Lender in the Collateral shall
be fully perfected.

     10.   The Note, and the Lender as holder of the Note, are exempt from the
usury provisions of Section 1 of Article XV of the California Constitution.

     AGREEMENT (hereinafter referred to as the "Agreement") entered into as of
October ___, 1995, between ADVANCED MICRO DEVICES, INC., a Delaware corporation

                                  WITNESSETH:

     WHEREAS, NexGen, AMD and AMD Merger Corporation, a Delaware corporation
(hereinafter referred to as the "Subsidiary"), propose to enter into an
Agreement and Plan of Merger expected to be signed and dated on October 20, 1995
(hereafter referred to as the "Merger Agreement") pursuant to which the
Subsidiary, which is wholly-owned by AMD, will be merged into NexGen (the

     NOW, THEREFORE, in consideration of the entry into the Merger Agreement of

Merger at any meeting of the stockholders of NexGen called for the purpose of
considering the Merger.  Concurrently with the Stockholder's execution of this
Agreement, the Stockholder has executed and delivered to AMD an irrevocable
proxy (the "AMD Proxy") in the form of Exhibit 1 attached hereto, appointing the
officers of AMD named therein, or either of them, as proxy for the Stockholder

                                   Exhibit A
                                   ---------

                                      

<PAGE>
 
     2.   Transfer Restriction.  The Stockholder shall not, prior to the meeting

of the stockholders of NexGen to be called for the purpose of considering the
Merger or the termination of the Merger Agreement, whichever is earlier, sell,
assign, otherwise transfer or encumber any of the Shares or execute any proxy
with respect to any of the Shares other than the AMD Proxy, or enter into any
agreement or other arrangement relating to the voting of any of the Shares which
proxy, agreement or arrangement is in any way inconsistent with the AMD Proxy.

     3.   Representations and Warranties of the Stockholder.  The Stockholder
          -------------------------------------------------                  
represents and warrants to AMD that:

          (a)  This Agreement is a valid and binding agreement of the
Stockholder, enforceable against the Stockholder in accordance with its terms;

          (b)  Neither the execution of this Agreement by the Stockholder nor
the consummation by the Stockholder of the transactions contemplated hereby will
constitute a violation of or default under, or conflict with, any contract,
commitment, agreement, understanding, arrangement or restriction of any kind by
which the Stockholder is bound;

          (c)  No consent, approval, order or authorization of any court,

Stockholder has not granted any proxy with respect to the Shares that is in
effect on the date hereof, and

          (e)  The Stockholder has not, with the exception of this Agreement and
the AMD Proxy, subjected the Shares to any voting trust or any other agreement,
understanding or arrangement.

     4.   Commitment of AMD.  If, as a result of the Stockholder's execution of
          -----------------                                                    
this Agreement and the AMD Proxy, any shares of AMD Common Stock received by the
Stockholder pursuant to the Merger are not deemed to have been registered under
the Securities Act of 1933, as amended, notwithstanding the fact that they have
been issued and sold pursuant to a registration statement on Form S-4, filed in
connection with the Merger, AMD will register such shares on a registration
statement on Form S-3 (the "S-3").  AMD will use its best efforts to have the S-
3 declared effective at the Effective Time, as defined in the Merger Agreement.
AMD shall use

     5.   Governing Law.  This Agreement shall be governed by and construed in
          -------------                                                       
accordance with the laws of the State of Delaware.

the Effective Time; or (b) the date as of which the Merger Agreement is
terminated in accordance with its terms or (c) nine months from the date hereof.

          --------------------                                                
damages would occur in the event any of the provisions hereof were not performed
in accordance with their specific terms or were otherwise breached.
Accordingly, the Stockholder agrees that AMD shall be entitled to an injunction
or injunctions to prevent breaches of the provisions hereof and to enforce
specifically the terms and provisions hereof in any court of competent
jurisdiction in the United States or any state thereof, in addition to any other
remedy with which AMD may be entitled at law or equity.

                              -------------------


     AGREEMENT (hereinafter referred to as the "Agreement") entered into as of
October ___, 1995, between Advanced Micro Devices, Inc., a Delaware corporation
(hereinafter referred to as "AMD"), and the stockholder (the "Stockholder") of
NexGen, Inc., a Delaware corporation (hereinafter referred to as "NexGen").

                                  WITNESSETH:

     WHEREAS, NexGen, AMD and AMD Merger Corporation, a Delaware corporation
(hereinafter referred to as the "Subsidiary"), propose to enter, or have entered
into an Agreement and Plan of Merger expected to be dated, or dated October 20,
1995 (hereinafter referred to as the "Merger Agreement"), pursuant to which the
Subsidiary, which is wholly-owned by AMD, will be merged into NexGen (the
"Merger"), and NexGen will become a wholly-owned subsidiary of AMD;

     WHEREAS, upon the consummation of the Merger and in connection therewith,
the Stockholder will become the owner of shares of Common Stock of AMD
(hereinafter referred to as the "AMD Shares"); and

     WHEREAS, it is intended that the transactions contemplated by the Merger
Agreement will be treated as a "pooling of interests" in accordance with
generally accepted accounting principles and the applicable General Rules and
Regulations published by the Securities and Exchange Commission (the
"Commission").

     NOW, THEREFORE, in consideration of the promises and the mutual agreements,
provisions and covenants set forth in the Merger Agreement, and hereinafter in
this Agreement, it is hereby agreed as follows:

     1.   The Stockholder hereby agrees that:

          (a)  He may be deemed to be (but does not hereby admit to be) an
"affiliate" of NexGen within the meaning of Rule 145 under the Securities Act of
1933, as amended (the "Securities Act"), and Accounting Series Release No. 130,
as amended, of the Commission.

          (b)  He will not sell or otherwise reduce his risk relative to the AMD
Shares or any part thereof until such time after the Effective Time, as defined
in the Merger Agreement, of the Merger as financial results covering at least
thirty (30) days of the post-Effective Time combined operations of AMD and
NexGen have been, within the meaning of said Accounting Series Release No. 130,
as amended, filed by AMD with the Commission or

                                   Exhibit B
                                   ---------


<PAGE>
 
published by AMD in an Annual Report on Form 10-K, a Quarterly Report on Form
10-Q, a Current Report on Form 8-K, a quarterly earnings report, a press release
or other public issuance which includes combined sales and income of NexGen and
AMD.  AMD agrees to make such filing or publication as soon as practicable.

          (c)  Subject in any event to paragraph (b) of this Section 1, he
agrees not to offer, sell, pledge, transfer or otherwise dispose of any of the
AMD Shares unless at that time either:

               (i)   such transaction shall be permitted pursuant to the
provisions of Rule 145(d) under the Securities Act;

               (ii)  counsel representing the Stockholder, satisfactory to AMD,
shall have advised AMD in a written opinion letter satisfactory to AMD and AMD's
counsel and upon which AMD and its counsel may rely, that no registration under
the Securities Act would be required in connection with the proposed sale,
transfer or other disposition;

               (iii) a registration statement under the Securities Act covering
the AMD Shares proposed to be sold, transferred or otherwise disposed of,
describing the manner and terms of the proposed sale, transfer or other
disposition, and containing a current prospectus under the Securities Act, shall
be effective under the Securities Act; or

               (iv)  an authorized representative of the Commission shall have
rendered written advice to the Stockholder (sought by the Stockholder or counsel
to the Stockholder, with a copy thereof and of all other related communications
delivered to AMD) to the effect that the Commission would take no action, or
that the staff of the Commission would not recommend that the Commission take
action, with respect to the proposed sale, transfer or other disposition if
consummated.

          (d)  (1)   Until the financial results described in paragraph (b) of
this Section 1 have been filed or published as described therein, and until a
public sale of the AMD Shares represented by such certificate has been made in
compliance with one of the alternative conditions set forth in the subparagraphs
of paragraph (c) of this Section 1, all certificates representing the AMD Shares
deliverable to the Stockholder pursuant to the Merger Agreement and in
connection with the Merger and any certificates subsequently issued with respect
thereto or in substitution therefor shall bear a legend substantially as
follows:

                                       2

<PAGE>
 
          "The shares represented by this certificate may not be offered, sold,
     pledged, transferred or otherwise disposed of except in accordance with the
     requirements of the Securities Act of 1933, as amended, and the other
     conditions specified in the Affiliate Agreement dated as of October ___,
     1995, between Advanced Micro Devices, Inc. and the registered holder, a
     copy of which Affiliate Agreement may be inspected by the holder of this
     certificate at the offices of Advanced Micro Devices, Inc., or Advanced
     Micro Devices, Inc. will furnish a copy thereof to the holder of this
     certificate upon written request and without charge."

AMD, at its discretion, may cause stop transfer orders to be placed with its
transfer agent(s) with respect to the certificates for the AMD Shares but not as
to the certificates for any part of the AMD Shares as to which said legend is no
longer appropriate as hereinabove provided.

               (2)   Notwithstanding paragraph (d)(1) of this Section 1, at any
time after the financial results described in paragraph (b) of this Section 1
have been filed or published as described therein, any or all certificates
representing the AMD Shares shall, at the written request of the Stockholder and
upon surrender of such certificates to the transfer agent for AMD Common Stock,
be replaced by stock certificates representing the AMD Shares bearing only the
following legend:

               "The shares represented by this certificate may not be offered,
          sold, pledged, transferred or otherwise disposed of except in
          compliance with paragraph (d) of Rule 145 promulgated by the
          Securities and Exchange Commission."

The reference in the foregoing legend to Rule 145 shall not preclude, however,
the alternative of a transaction in compliance with subparagraphs (ii), (iii) or
(iv) of paragraph (c) of this Section 1.

          (e)  The Stockholder will observe and comply with the Securities Act
and the General Rules and Regulations thereunder, as now in effect and as from
time to time amended and including those hereafter enacted or promulgated, in
connection with any offer, sale, pledge or transfer or other disposition of the
AMD Shares or any part thereof.

     2.   From and after the Effective Time of the Merger and for so long as
necessary in order to permit the Stockholder to sell the AMD Shares pursuant to
Rule 145 and, to the extent applicable, Rule 144 under the Securities Act, AMD
will use its best efforts to file on a timely basis all reports required to be
filed by it pursuant to Section 13 of the Securities Exchange Act

                                       3

<PAGE>
 
of 1934, referred to in paragraph (c)(l) of Rule 144 under the Securities Act
(or, if applicable, AMD will use its best efforts to make publicly available the
information regarding itself referred to in paragraph (c)(2) of Rule 144) in
order to permit the Stockholder to sell, pursuant to the terms and conditions of
Rule 145 and the applicable provisions of Rule 144, the AMD Shares.

     3.   No waiver by any party hereto of any condition or of any breach of any
provision of this Agreement shall be effective unless in writing.

     4.   All notices, requests, demands or other communications which are
required or may be given pursuant to the terms of this Agreement shall be in
writing and shall be deemed to have been duly given if delivered by hand or
(except where receipt thereof is specifically required for purposes of this
Agreement) mailed by registered or certified mail, postage prepaid, as follows:

     Re:  Merger of AMD Merger
          Corporation and NexGen, Inc.
          ----------------------------

Gentlemen:

     This opinion is furnished to you pursuant to Section 8.7 of the Agreement
and Plan of Merger dated October 20, 1995 (the "Agreement") among Advanced Micro
Devices, Inc. ("AMD"), AMD Merger Corporation ("AMD Merger") and NexGen, Inc.
("NexGen").  We have acted as counsel for NexGen in connection with the
transactions contemplated by the Agreement.  Unless otherwise defined or unless
the context otherwise requires, all capitalized terms used herein shall have the
meanings given them in the Agreement.

     We have performed such investigation, research and review as we deem
reasonably sufficient for the purpose of rendering our opinion, and as to
questions of fact, we have relied, to the extent we deem proper, upon
certificates of officers and other representatives of NexGen and of government
officials.  We have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures on original documents and the
conformity to original documents of all copies submitted to us.  As used in our
opinion, the expressions "to our knowledge" and "known to us" mean that solely
after an inquiry of attorneys within this firm who perform legal services for
NexGen and its subsidiaries, receipt of a certificate executed by one or more
officers of NexGen covering such matters which we believe are sufficient for the
purpose of expressing the opinions contained herein, and such other
investigation, research, and review as we have performed in the course of our
services for NexGen and its subsidiaries in connection with the preparation of
the Agreement, the S-4, the Prospectus and the Proxy Statement, nothing has come
to our attention which causes us to believe that the opinions expressed herein
are factually incorrect, but beyond

                                   Exhibit D
                                   ---------

that, we have made no independent factual investigation for the purpose of
rendering this opinion.

     Our opinion is subject to the following qualifications:

          (1)  Our opinion is subject to (a) the effect of bankruptcy,
insolvency, reorganization, moratorium and other similar laws now or hereafter
in effect generally affecting creditors' rights; (b) the limitations imposed by
applicable state law, federal law and equitable principles upon the
enforceability of any of the remedies, covenants or other provisions of the
Agreement and upon the availability of injunctive relief or other equitable
remedies, including, without limitation, the effect of court decisions invoking
statutes or principles of equity, which have held that certain covenants and
provisions of agreements are unenforceable where: (i) the breach of such
covenants or provisions imposes restrictions or burdens upon a party and it
cannot be demonstrated that the enforcement of such restrictions or burdens is
reasonably necessary for the protection of the other party, or (ii) a party's
enforcement of such covenants or provisions under the circumstances would
violate such party's implied covenants of good faith and fair dealing; and (c)
the power of the federal and state courts to refuse to enforce (or to stay the
enforcement of) any provision which purports to waive the rights of NexGen to
assert claims or defenses available to it by statute, common law or equity;

          (2)  Except with respect to paragraphs 2, 3, 4 and 8 below, our
opinion is limited to the effect of the laws of the State of Delaware, the State
of California and the federal laws of the United States, and we express no
opinion with respect to the laws of any other jurisdiction, or the effect
thereof on the transactions contemplated by the Agreement. To the extent the
opinions set forth in paragraphs 2, 3, 4 and 8 relate to matters involving
subsidiaries of NexGen which are incorporated in a jurisdiction other than one
of the states of the United States of America, such opinions are based upon and
subject to the opinions of foreign counsel attached hereto (the "Foreign
Opinions") and shall be interpreted to be (i) no broader in scope than the
Foreign Opinions and (ii) subject to any limitations, exceptions or exclusions
set forth in the Foreign Opinions.

          (3)  In making our examination of documents and instruments executed
by persons or entities other than NexGen, we have assumed, without
investigation, the power and legal capacity of each such person or other entity
to enter into and perform all its obligations under such documents and
instruments, the due authorization by each such other person or entity of all
requisite action with respect to such documents and instruments and the due
execution and delivery by each such other person or entity of such documents and
instruments.

          (4)  As used in our opinion, the term "material" means material to the
assets, properties, business or financial condition of NexGen and its
subsidiaries taken as a whole.

     Based upon and subject to the foregoing, we are of the opinion that:

          (1)  NexGen is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware, with all requisite
corporate power to own, lease and operate all of its properties and assets, to
carry on its business as it is now being conducted, and to merge with AMD Merger
pursuant to the terms of the Agreement.

          (2)  Each subsidiary of NexGen is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, with all requisite corporate power to own, lease and operate all
of its properties and assets and to carry on its business as it is now being
conducted, subject to the exceptions and qualifications set forth in the Foreign
Opinions.

          (3)  NexGen is and each subsidiary of NexGen is duly qualified and in
good standing as a foreign corporation in each jurisdiction in which the nature
of its business or the owning and leasing of its properties makes such
qualification necessary, except where the failure to so qualify would not have a
material adverse effect on NexGen, subject to the exceptions and qualifications
set forth in the Foreign Opinions.

          (4)  Except as disclosed in the schedules to the Agreement and
subject to the exceptions and qualifications set forth in the Foreign Opinions,
the execution and delivery of the Agreement does not violate any terms or
provisions of any law or regulation, or of the certificate of incorporation or
bylaws of NexGen or, to our knowledge, of any material indenture, mortgage or
other agreement or instrument by which NexGen or any of its subsidiaries is
bound or, to our knowledge, conflict with or constitute a material default, or
result in the material breach of or acceleration of any material obligation (or
entitle any party so to accelerate, assuming the giving of notice or lapse of
time or both) or the creation of any material lien, charge, pledge, security
interest or other encumbrance upon any of the property of NexGen or any
subsidiary of NexGen, under any term or provision of the certificate of
incorporation or bylaws of NexGen or any subsidiary of NexGen, or under any
material mortgage, lien, lease, agreement, instrument, judgment, decree, order,
arbitration award, writ or injunction to which NexGen or any subsidiary of
NexGen is a party or by which NexGen or any subsidiary of NexGen is bound.

          (5)  The Board of Directors and stockholders of NexGen have taken all
corporate action required by law, NexGen's certificate of incorporation or
bylaws or otherwise required and known to us, to authorize the execution and
delivery of the Agreement and the consummation of the Merger.  The Agreement is
a valid and binding agreement of NexGen, enforceable as to NexGen in accordance
with its terms, except as rights to indemnity under the Agreement may be limited
under applicable law.

          (6)  The stockholders of NexGen have approved the Merger in compliance
with the Delaware General Corporation Law and NexGen's certificate of
incorporation and bylaws, and to our knowledge no other consent, approval or
other action by, or notice to or filing with, any governmental or administrative
agency or authority is required or necessary to be obtained by NexGen in
connection with the Merger other than the filing of a Form 8-K reporting the
Closing with the SEC.

          (7)  The authorized and outstanding capital stock of NexGen is as set
forth Section 2.2 of the Agreement, and all of such shares of the capital stock
of NexGen outstanding as of the date hereof are, validly issued, fully paid,
nonassessable and free of preemptive rights.

          (8)  Other than directors' qualifying shares and subject to the
exceptions and qualifications set forth in the Foreign Opinions, the shares of
capital stock of each subsidiary of NexGen are owned directly or indirectly by
NexGen, are validly issued, fully paid and nonassessable and are, to our
knowledge, owned free and clear of any liens, claims, charges or encumbrances.

          (9)  (a)  To our knowledge, there are no franchises, leases,
contracts, agreements or documents relating to NexGen of a character required to
be disclosed in the S-4, the Prospectus or the Proxy Statement or in any
amendment or supplement thereto, or to be filed as exhibits to the S-4, which
are not disclosed or filed, as required.

               (b)  To our knowledge, the statements in the S-4, the Prospectus
and the Proxy Statement, and in information incorporated by reference in the
Prospectus, describing legal matters, proceedings or documents relating to
intellectual property, real property, leases, contracts, agreements or
litigation relating to NexGen, and describing the income tax consequences of the
Merger to the stockholders of NexGen, are accurate in all material respects and
such descriptions fairly present all material information required to be
included with respect thereto.

               (c)  The S-4, the Prospectus and the Proxy Statement, and any
amendment or supplement thereto and each document incorporated by reference in
the Prospectus, insofar as they relate to NexGen, comply as to form in all
material respects with the requirements of the Act and the rules and regulations
promulgated thereunder. We express no opinion as to the financial statements or
other financial data included in any of the documents mentioned in this
paragraph.

               (d)  We have participated in conferences with representatives of
AMD and NexGen, accountants for AMD and NexGen, and counsel for AMD concerning
the Agreement, the S-4, the Prospectus and the Proxy Statement. Although we have
not independently verified the accuracy, completeness or fairness of the
statements contained in the S-4, the Prospectus and the Proxy Statement, nothing
has come to our attention, as a result of our participation in such discussions,
to cause us to believe that, either on the effective date of the S-4 or on the
date hereof, the S-4, the Prospectus, the Proxy Statement, or any amendment or
supplement thereto, insofar as they relate to NexGen, contained

or contain any untrue statement of a material fact or omitted or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.  We express no opinion as to the financial statements or other
financial data included in any of the documents mentioned in this paragraph.

     This opinion is solely for the benefit of AMD in connection with the
closing of the Merger and may not be relied upon in any manner by any other
person or for any other purpose and shall not be made available to or filed with
any other person or governmental agency by AMD, except as required by law,
without the prior written consent of the undersigned.

                                             Very truly yours,

     Re:  Merger of AMD Merger
          Corporation and NexGen, Inc.
          ----------------------------

Gentlemen:

     This opinion is furnished to you pursuant to Section 9.5 of the Agreement
and Plan of Merger dated October 20, 1995 (the "Agreement") among Advanced Micro
Devices, Inc. ("AMD"), AMD Merger Corporation ("AMD Merger") and NexGen, Inc.
("NexGen"). We have acted as counsel for AMD and AMD Merger in connection with
the transactions contemplated by the Agreement. Unless otherwise defined or
unless the context otherwise requires, all capitalized terms used in this
opinion shall have the meanings assigned them in the Agreement.

     We have performed such investigation, research and review as we deem
reasonably sufficient for the purpose of rendering our opinion, and as to
questions of fact, we have relied, to the extent we deem proper, upon
certificates of officers and other representatives of AMD and AMD Merger and of
government officials. We have assumed the authenticity of all documents
submitted to us as originals, the genuineness of all signatures on original

mean that solely after an inquiry of attorneys within this firm who perform

or more officers of AMD and AMD Merger covering such matters which we believe

such other investigation, research and review as we have performed in the course
of our services for AMD and AMD Merger in connection with the preparation of the
Agreement, the S-4, the Prospectus and the Proxy Statement, nothing has come to
our attention which causes us to believe that the opinions expressed herein are
factually

                                   Exhibit E
                                   ---------

incorrect, but beyond that, we have made no independent factual investigation
for the purpose of rendering this opinion.

     Our opinion is subject to the following qualifications:

     (1)  Our opinion is subject to (a) the effect of bankruptcy, insolvency,
reorganization, moratorium and other similar laws now or hereafter in effect
generally affecting creditors' rights; (b) the limitations imposed by applicable
state law, federal law and equitable principles upon the enforceability of any
of the remedies, covenants and other provisions of the Agreement and upon the
availability of injunctive relief or other equitable remedies, including,
without limitation, the effect of court decisions invoking statutes or
principles of equity, which have held that certain covenants and provisions of
agreements are unenforceable where: (i) the breach of such covenants or
provisions imposes restrictions or burdens upon a party and it cannot be
demonstrated that the enforcement of such restrictions or burdens is reasonably
necessary for the protection of the other party, or (ii) a party's enforcement
of such covenants or provisions under the circumstances would violate such
party's implied covenants of good faith and fair dealing; and (c) the power of
the federal and state courts to refuse to enforce (or to stay the enforcement
of) any provision which purports to waive the rights of AMD to assert claims or
defenses available to it by statute, common law or equity.

     (2)  Except with respect to paragraphs 2, 3, 9 and 12, our opinion is
limited to the effect of the laws of the State of Delaware, the State of
California and the federal laws of the United States, and we express no opinion
with respect to the laws of any other jurisdiction, or the effect thereof on the
transactions contemplated by the Agreement. Our opinion set forth in paragraph
12 is based on our examination of the securities laws of the several states and
the rules and regulations of the authorities administering such laws, all as
reported in unofficial compilations conveniently available to us. We have not
obtained any special rulings of such authorities or opinions of counsel in such
jurisdictions. To the extent the opinions set forth in paragraphs 2, 3, 4 and 9
relate to matters involving subsidiaries of AMD which are incorporated in a
jurisdiction which is other than one of the states of the United States of
America and to the extent the opinions set forth in paragraph 3 relate to the
good standing of AMD International Sales and Service, Ltd. as a foreign
corporation in any jurisdiction other than one of the states of the United
States of America, such opinions are based upon and subject to the opinions of
foreign counsel attached hereto (the "Foreign Opinions") and shall be

Board of Directors

Page 3



interpreted to be (i) no broader in scope than the Foreign Opinions and (ii)
subject to any limitations, exceptions or exclusions set forth in the Foreign
Opinions.

     (3)  In making our examination of documents and instruments executed by
persons or entities other than AMD and AMD Merger, we have assumed, without
investigation, the power and legal capacity of each such person or other entity
to enter into and perform all its obligations under such documents and
instruments, the due authorization by each such other person or entity of all
requisite action with respect to such documents and instruments and the due
execution and delivery by each such other person or entity of such documents and
instruments.

     (4)  As used in our opinion, the term "material" means material to the
assets, properties, business or financial condition of AMD and its subsidiaries
taken as a whole.

     Based upon and subject to the foregoing, we are of the opinion that:

     (1)  AMD is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware, with all requisite corporate
power to own, lease and operate all of its properties and assets, and to carry
on its business as it is now being conducted.

     (2)  Each subsidiary of AMD is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, with all requisite corporate power to own all of its properties
and assets, to carry on its business as it is now being conducted; and AMD
Merger has all requisite power to merge into NexGen pursuant to the terms of the
Agreement.

     (3)  AMD is, and each subsidiary of AMD is, duly qualified and in good
standing as a foreign corporation in each jurisdiction in which the nature of
its business or the owning and leasing of its properties makes such
qualification necessary, except where the failure to so qualify would not have a
material adverse effect on AMD.

     (4)  Except as disclosed in the schedules to the Agreement, the execution
and delivery of the Agreement does not violate any terms or provisions of any
law or regulation, or of the certificate of incorporation or bylaws of AMD or
AMD Merger or, to our knowledge, of any material indenture, mortgage or other
agreement or instrument by which AMD or any of its subsidiaries


<PAGE>
 
Board of Directors

is bound or, to our knowledge, conflict with or constitute a material default,
or result in the material breach of or acceleration of any material obligation
(or entitle any party to so accelerate, assuming the giving of notice or lapse
of time or both) or the creation of any material lien, charge, pledge, security
interest or other encumbrance upon any of the property of AMD or any of its
subsidiaries, under any term or provision of the certificate of incorporation or
bylaws of AMD or any of its subsidiaries, or under any material mortgage, lien,
lease, agreement, instrument, judgment, decree, order, arbitration award, writ
or injunction to which AMD or any of its subsidiaries is a party or by which AMD
or any of its subsidiaries is bound.

     (5)  The Boards of Directors of AMD and AMD Merger have taken all corporate
action required by law, their certificates of incorporation, or bylaws or
otherwise required and known to us, to authorize the execution and delivery of
the Agreement and the consummation of the Merger. The Agreement is a valid and
binding agreement of AMD and AMD Merger, enforceable as to AMD and AMD Merger in
accordance with its terms, except as rights to indemnity under the Agreement may
be limited under applicable law.

     (6)  The execution and delivery of the Agreement and the consummation of
the Merger have been authorized and approved by AMD as the sole stockholder of
AMD Merger.

     (7)  Neither AMD's certificate of incorporation nor its bylaws require the
Merger to be approved by the stockholders of AMD; the stockholders of AMD have
approved the Merger in compliance with the applicable policies of the New York
Stock Exchange, Inc. ("NYSE"), and no other consent, approval or other action
by, or notice to or filing with, any governmental or administrative agency or
authority is required or necessary to be obtained by AMD in connection with the
Merger other than the filing of a Form 8-K reporting the Closing with the SEC
and the filing of a notice with the NYSE of issuance of the shares of AMD common
stock to be issued in connection with the Merger.

     (8)  Other than for transactions between AMD and its employees, the
authorized and outstanding capital stock of AMD is as set forth in Section 3.2
of the Agreement, and all of such outstanding shares of the capital stock of
AMD, including those issued in transactions between AMD and its employees, are
validly issued, fully paid, nonassessable and free of preemptive rights.

indirectly by AMD, are validly issued, fully paid and nonassessable and are, to
our knowledge, owned free and clear of any liens, claims, charges or
encumbrances.

     (10) The certificates evidencing the AMD shares to be delivered under the
Agreement by AMD are in due and proper form, and when duly countersigned by the
Exchange Agent, and delivered in accordance with the provisions of the
Agreement, the AMD shares represented thereby will be duly authorized and
validly issued, fully paid and nonassessable, will not have been issued in
violation of or subject to any preemptive rights and will conform as to matters
of law in all material respects to the description thereof contained in the S-4,
the Prospectus and the Proxy Statement. In expressing the opinion in this
paragraph we have assumed that the certificates conform as to form with the
specimen of the certificates examined by us, which fact we have not verified by
inspection of the individual certificates.

     (11) (a)  The S-4 has become effective under the Act, and to our knowledge,
no stop order suspending the effectiveness of the S-4 or preventing the use of
the Proxy Statement has been issued and, to the best of our knowledge, no
proceedings for that purpose have been instituted or are pending or threatened
by the SEC.

          (b)  To our knowledge, there are no franchises, leases, contracts,
agreements or documents relating to AMD of a character required to be disclosed
in the S-4, the Prospectus or the Proxy Statement or in any amendment or
supplement thereto, or to be filed as exhibits to the S-4, which are not
disclosed or filed, as required.

          (c)  To our knowledge, the statements in the S-4, the Prospectus and
the Proxy Statement, and in each amendment and supplement thereto, and in each
document incorporated by reference in the Prospectus, describing legal matters,
proceedings or documents relating to intellectual property, real property,
leases, contracts, agreements or litigation relating to AMD and describing the
income tax consequences of the Merger to the stockholders of NexGen, are
accurate in all material respects and such descriptions fairly present all
material information required to be included with respect thereto.

          (d)  The S-4, the Prospectus and the Proxy Statement, and any
amendment or supplement thereto, and each document incorporated by reference in
the Prospectus, insofar as they relate to AMD, comply as to form in all material
respects with the requirements of the Act and the rules and regulations

promulgated thereunder. We express no opinion as to the financial statements or
other financial data included in any of the documents mentioned in this
paragraph.

          (e)  We have participated in conferences with representatives of AMD
and NexGen, AMD's and NexGen's accountants, and counsel for NexGen concerning
the Agreement, the S-4, the Prospectus and the Proxy Statement. Although we have
not independently verified the accuracy, completeness or fairness of the
statements contained in the S-4, the Prospectus and the Proxy Statement, nothing
has come to our attention, as a result of our participation in such discussions,
to cause us to believe that, either on the effective date of the S-4 or on the
date hereof, the S-4, the Prospectus and the Proxy Statement, or any amendment
or supplement thereto, insofar as they relate to AMD, contained or contain any
untrue statement of a material fact or omitted or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. We
express no opinion as to the financial statements or other financial data
included in any of the documents mentioned in this paragraph.

     (12) AMD has obtained such consents, approvals, orders and authorizations
of, and has made such registrations, qualifications, designations, declarations
and filings with, such state securities administrators as are necessary to issue
the AMD shares to be issued in connection with the Merger in compliance with the
securities registration or qualification laws, rules and regulations of such
states, except for those filings that may be made after the Effective Date of
the Merger.

     The opinion set forth above is solely for the benefit of NexGen in
connection with the Merger and may not be relied upon in any manner by any other
person or for any other purpose and shall not be made available to or filed with
any other person or governmental agency by NexGen, except as required by law,
without the prior written consent of the undersigned.

                                             Very truly yours,

                           MEETINGS OF STOCKHOLDERS
                           ------------------------

     Section 1.  Subject to the rights of holders of any class or series of
stock of the corporation having a preference over the Common Stock as to
dividends or upon liquidation to elect directors under specified circumstances,
nominations for the election of directors may be made by or at the direction of
the Board of Directors or by any stockholder entitled to vote in the election of
directors generally.  Subject to the foregoing, only a stockholder of record
entitled to vote in the election of directors generally may nominate one or more
persons for election as directors at a meeting of stockholders and only if
written notice of such stockholder's intent to make such nomination or
nominations has been given, either by personal delivery or by United States
mail, postage prepaid, to the Secretary of the corporation and has been received
by the Secretary not later than the following dates:  (i) with respect to an
election to be held at an annual meeting of stockholders, 90 days in advance of
such meeting; and (ii) with respect to an election to be held at a special
meeting of stockholders for the election of directors, the close of business on
the tenth day following the date on which notice of such meeting if first given
to stockholders.

     Each such notice shall set forth:

          (a) the name and address of the stockholder who intends to make the
     nomination and of the person or persons to be nominated;

          (b) a representation that the stockholder is a holder of record of
     stock of the corporation entitled to vote at
<PAGE>
 
     such meeting and intends to appear in person or by proxy at the meeting to
     nominate the person or persons specified in the notice;

          (c) a description of all arrangements or understandings between the
     stockholder and each nominee and any other person or persons (naming such
     person or persons) pursuant to which the nomination or nominations are to
     be made by the stockholder; and

          (d) such other information regarding each nominee proposed by such
     stockholder as would be required to be included in a proxy statement filed
     pursuant to the proxy rules of the Securities and Exchange Commission, had
     the nominee been nominated, or intended to be nominated, by the Board of
     Directors.

     To be effective, each notice of intent to make a nomination given hereunder
shall be accompanied by the written consent of each nominee to serve as a
director of the corporation if elected.

     The chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not properly brought before the
meeting in accordance with the provisions hereof and, if he should so determine,
he shall declare to the meeting that such nomination was not properly brought
before the meeting and shall not be considered.

     Section 2.  Annual meetings of the stockholders shall be held on the third
Wednesday in May if not a legal holiday, and if a legal holiday, then at the
next secular day following, at 4:00 p.m., or at such other date and time as
shall be designated from time to time by the Board of Directors and stated in
the notice of the meeting, at which they shall elect by plurality vote, a Board
of Directors, and transact such other business as may properly be brought before
the meeting.

     Section 3.  Written notice of the annual meeting stating the place, date
and hour of the meeting shall be given to each stockholder entitled to vote at
such meeting not less than ten nor more than sixty days before the date of the
meeting.

     Section 4.  The officer who has charge of the stock ledger of the
corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during

                                       2
<PAGE>
 
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held.  The list shall also be produced and kept
at the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.

     Section 5.  Special meetings of the stockholders, for any purpose or
purposes, unless otherwise prescribed by statute or by the Certificate of
Incorporation, may be called by the chairman and shall be called by the chairman
or secretary at the request in writing of a majority of the Board of Directors.

     Section 6.  Written notice of a special meeting stating the place, date and
hour of the meeting and the purpose or purposes for which the meeting is called,
shall be given not less than ten nor more than sixty days before the date of the
meeting, to each stockholder entitled to vote at such meeting.

     Section 7.  At any special meeting of stockholders only such business shall
be conducted as shall have been set forth in the notice of special meeting.  At
an annual meeting of stockholders, only such business shall be conducted as
shall have been properly brought before the meeting.  To be properly brought
before an annual meeting, business must be (i) specified in the notice of
meeting (or any supplement thereto) given by or at the direction of the Board of
Directors, (ii) otherwise properly brought before the meeting by or at the
direction of the Board of Directors, or (iii) otherwise (a) properly requested
to be brought before the meeting by a stockholder of record entitled to vote in
the election of directors generally, and (b) constitute a proper subject to be
brought before such meeting.

     For business (other than the election of directors) to be properly brought
before an annual meeting by a stockholder, the stockholder must have given
timely notice thereof in writing to the Secretary of the corporation.  To be
timely, a stockholder's notice must be given, either by personal delivery or by
United States mail, postage prepaid, to the Secretary of the corporation and
must have been received by the Secretary not later than 90 days in advance of
such meeting.  A stockholder's notice to the Secretary shall set forth as to
each matter (other than the election of directors) the stockholder proposes to
bring before the annual meeting (a) a brief description of the business desired
to be brought before the annual meeting and the reasons for conducting such
business at the annual meeting, (b) the name and address, as they appear on the
corporation's books, of the stockholder intending to propose such business, (c)
the class and number of shares of capital stock of the corporation which are

                                       3
<PAGE>
 
beneficially owned by the stockholder, (d) a representation that the stockholder
is a holder of record of capital stock of the corporation entitled to vote at
such meeting and intends to appear in person or by proxy at the meeting to
present such business, and (e) any material interest of the stockholder in such
business.

     Notwithstanding anything in the Bylaws to the contrary, no business shall
be conducted at any annual meeting except in accordance with the procedures set
forth in this Section 7.  The chairman of the annual meeting shall, if the facts
warrant, determine and declare to the meeting that (i) the business proposed to
be brought before the meeting was not a proper subject therefor and/or (ii) such
business was not properly brought before the meeting and in accordance with the
provisions of this Section 7, and, if he should so determine, he shall so
declare to the meeting and any such business not properly brought before the
meeting or not a proper subject therefor shall not be transacted.
Notwithstanding compliance with the requirements of this Section 7, the chairman
presiding at any meeting of the stockholders may, in his sole discretion, refuse
to allow a stockholder or stockholder's representative to present any proposal
which the corporation would not be required to include in a proxy statement
under any rule promulgated by the Securities and Exchange Commission.

     For purposes of this Section 7, and Section 1 of Article II of these
Bylaws, reference to a requirement to deliver notice to the corporation a set
number of days in advance of an annual meeting shall mean that such notice must
be delivered such number of days in advance of the first anniversary of the
preceding year's annual meeting; provided, however, that in the event that the
                                 --------  -------                            
date of the annual meeting is advanced by more than 30 days or delayed by more
than 60 days from the first anniversary of the preceding year's annual meeting,
notice by the stockholder to be timely must be so delivered not later than the
close of business on the later of the 60th day prior to such annual meeting or
the 10th day following the day on which notice of such meeting is first given to
stockholders.  For purposes of these Bylaws, notice of such meeting shall be
deemed to be first given to stockholders when disclosure of such date is first
made in a press release reported by the Dow Jones News Service, Associated Press
or comparable national news service or in a document publicly filed by the
corporation with the Securities and Exchange Commission pursuant to Sections 13,
14 or 15(d) of the Securities Exchange Act of 1934.

     Section 8.  The holders of a majority of the stock issued and outstanding
and entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business

                                       4
<PAGE>
 
except as otherwise provided by statute or by the Certificate of Incorporation.
If, however, such quorum shall not be present or represented at any meeting of
the stockholders, the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present or represented.  At such adjourned meeting, at which a quorum
shall be present or represented, any business may be transacted which might have
been transacted at the meeting as originally notified.  If the adjournment is
for more than thirty days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

     Section 9.  When a quorum is present at any meeting, the vote of the
holders of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of applicable law,
rule or regulation or of the Certificate of Incorporation, a different vote is
required in which case such express provision shall govern and control the
decision of such question.

     Section 10.  Each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder, but no proxy shall be voted on
after three years from its date, unless the proxy provides for a longer period.

     Section 11.  Whenever the vote of stockholders at a meeting thereof is
required or permitted to be taken for or in connection with any corporate
action, by any provision of the statutes, the meeting and vote of stockholders
may be dispensed with if all of the stockholders who would have been entitled to
vote upon the action if such meeting were held shall consent in writing to such
corporate action being taken; or if the Certificate of Incorporation authorizes
the action to be taken with the written consent of the holders of less than all
of the stock who would have been entitled to vote upon the action if a meeting
were held, then on the written consent of the stockholders having not less than
such percentage of the number of votes as may be authorized in the Certificate
of Incorporation; provided that in no case shall the written consent be by the
holders of stock having less than the minimum percentage of the vote required by
statute for the proposed corporate action, and provided that prompt notice must
be given to all stockholders of the taking of corporate action without a meeting
and by less than unanimous written consent.

<PAGE>
 
     Section 12.  The date and time of the opening and the closing of the polls
for each matter upon which the stockholders will vote at a meeting shall be
announced at the meeting by the person presiding over the meeting.  The Board of
Directors of the corporation may to the extent not prohibited by law adopt by
resolution such rules and regulations for the conduct of the meeting of
stockholders as it shall deem appropriate.  Except to the extent inconsistent
with such rules and regulations as adopted by the Board of Directors, the
chairman of any meeting of stockholders shall have the right and authority to
prescribe such rules, regulations and procedures and to do all such acts as, in
the judgment of such chairman, are appropriate for the proper conduct of the
meeting.  Such rules, regulations or procedures, whether adopted by the Board of
Directors or prescribed by the chairman of the meeting, may to the extent not
prohibited by law include, without limitation, the following:  (i) the
establishment of an agenda or order of business for the meeting; (ii) rules and
procedures for maintaining order at the meeting and the safety of those present;
(iii) limitations on attendance at or participation in the meeting to
stockholders of record of the corporation, their duly authorized and constituted
proxies or such other persons as the chairman of the meeting shall determine;
(iv) restrictions on entry to the meeting after the time fixed for commencement
thereof; and (v) limitations on the time allotted to questions or comments by
participants.  Unless, and to the extent, determined by the Board of Directors
or the chairman of the meeting, meetings of stockholders shall not be required
to be held in accordance with the rules of parliamentary procedure.

                                   DIRECTORS

     Section 1.  The number of directors which shall constitute the whole board
shall be not less than three (3) nor more than eleven (11).  The first board
shall consist of three (3) directors.  Thereafter, within the limits above
specified, the number of directors shall be determined by resolution of the
Board of Directors or by the stockholders at the annual meeting.  The directors
shall be elected at the annual meeting of the stockholders, except as provided
in Section 2 of this Article, and each director elected shall hold office until
his successor is elected and qualified.  Directors need not be stockholders.

     Section 2.  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, though less than a quorum, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and shall qualify, unless
sooner displaced.  If there are no directors in

                                       6
<PAGE>
 
office, then an election of directors may be held in the manner provided by
statute.  If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office.

     Section 3.  The business of the corporation shall be managed by or under
the direction of its Board of Directors which may exercise all such powers of
the corporation and do all such lawful acts and things as are not by statute or
by the Certificate of Incorporation or by these By-Laws directed or required to
be exercised or done by the stockholders.

     Section 4.  The provisions of Sections 1 and 2 of this Article are subject
to the rights, if any, of the holders of shares of any series of the Preferred
Stock of the corporation with respect to the election of directors in the event
the corporation defaults in the payment of dividends, the term of office of any
director so elected and the filling of any vacancy in the office of any director
so elected.

     Section 5.  The Board of Directors of the corporation may hold meetings,

     Section 6.  The first meeting of each newly elected Board of Directors
shall be held at such time and place as shall be fixed by the vote of the
stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present.  In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given hereinafter provided for special

on the written request of two directors.

     Section 9.  At all meetings of the board a majority of the directors shall
constitute a quorum for the transaction of business and the act of a majority of
the directors present at any meeting at which there is a quorum shall be the act
of the Board of Directors, except as may be otherwise specifically provided by
statute or by the Certificate of Incorporation.  If a quorum shall not be
present at any meeting of the Board of Directors, the directors present thereat
may adjourn the meeting from time to time, without notice other than

or committees shall have such name or names as may

                                       8

be determined from time to time by resolution adopted by the Board of Directors.

     Section 14.  The directors may be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at such meeting of the Board of Directors or a stated salary as
director.  No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.  Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

                                    -------
     Section 1.  Whenever, under the provisions of the statutes or of the
Certificate of Incorporation or of these by-laws, notice is required to be given

notice, but such notice may be given in writing, by mail, addressed to such

secretary of the corporation, certifying the number of shares owned by him in
the corporation.

     Section 2.  Any or all of the signatures on the certificate may be a
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is

such officer, transfer agent or registrar at the date of issue.

reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purpose as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

                                 ARTICLE VIII
                                 ------------
                                INDEMNIFICATION
                                ---------------

     Section 1.  Subject to Section 3 of this Article VIII, the Corporation
shall indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the Corporation) (a "third party proceeding") by reason of
the fact that he is or was a director or officer of the Corporation, or is or
was serving at the request of the Corporation as a director or officer of
another Corporation, partnership, joint venture, trust or other enterprise,
including service with respect to employee benefit plans (an "indemnitee"),
against all expenses, liability and loss (including attorneys' fees, judgments,
fines ERISA excise taxes or penalties and amounts paid in settlement) actually
and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
                                                           ---------------   
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

                                       15
<PAGE>
 
     Section 2.  Subject to Section of this Article VIII, the Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor (together with third party
proceedings, "proceedings") by reason of the fact that he is or was a director
or officer of the Corporation, or is or was serving at the request of the
Corporation as a director or officer of another Corporation, partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans (an "indemnitee"), against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

                       AUTHORIZATION OF INDEMNIFICATION
                       --------------------------------

     Section 3.  Any indemnification under this Article VIII (unless ordered by
a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director or officer is
proper in the circumstances because he has not met the applicable standard of
conduct set forth in Section 1 or Section 2 of this Article VIII, as the case
may be. Such determination shall be made (i) by a majority vote of the directors
who were not parties to such action, suit or proceeding, even though less than a
quorum, or (ii) if there are no such directors or if such directors so direct,
by independent legal counsel in a written opinion, or (iii) by the stockholders.
To the extent, however, that a director or officer of the Corporation has been
successful on the merits or otherwise in defense of any action, suit or
proceeding, described above, or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith, without the
necessity of authorization in the specific case.

                              GOOD FAITH DEFINED
                              ------------------

     Section 4.  For the purposes of any determination under Section 3 of this
Article VIII, a person shall be deemed to have

                                       16
<PAGE>
 
acted or refrained from acting in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Corporation, or,
with respect to any criminal action or proceeding, to have had no reasonable
cause to believe his action or forbearance from acting was unlawful, if his
action, or forbearance as the case may be, is based on the records or books of
account of the Corporation or other enterprise, or on information supplied to
him by the officers of the Corporation or other enterprise in the course of
their duties, or on the advice of legal counsel for the Corporation or other
enterprise or on information or records given or reports made to the Corporation
or other enterprise by an independent certified public accountant or by an
appraiser or other expert selected with reasonable care by the Corporation or
other enterprise.  The term "other enterprise" as used in this Section 4 shall
man any other Corporation or any partnership, joint venture, trust, employee
benefit plan or other enterprise which such person is or was serving at the
request of the Corporation as a director, officer or employee.  The provisions
of this Section 4 shall not be deemed to be exclusive or to limit in any way the
circumstances in which a person may be deemed to have met the applicable
standard of conduct set forth in Sections 1 or 2 of this Article VIII, as the
case may be.

          PROCEDURES FOR INDEMNIFICATION AND ADVANCEMENT OF EXPENSES
          ----------------------------------------------------------

     Section 5.

          (a) Any indemnification under Sections 1 or 2 or advancement of
expenses under Section 6 (accompanied by the requisite undertaking) of this
Article VIII shall be made promptly, and in any event within ninety days, upon
the written request of the person seeking indemnification or advancement of
expense, unless, in the case of indemnification, a determination is reasonably
and promptly made by the Board of Directors by a majority vote of the directors
who are not parties to the action, suit or proceeding in question, even though
less than a quorum, that such person acted in a manner set forth in such
Sections 1 or 2, as the case may be, as to justify the Corporation's not
indemnifying such person.  In the event there are no such directors or if such
directors so direct, the Board of Directors shall promptly direct that
independent legal counsel shall give its opinion in writing whether such person
acted in the manner set forth in such Sections 1 or 2, as the case may be, as to
justify the Corporation's not indemnifying such person.

          (b) The right to indemnification or advancement of expenses granted by
this Article shall be enforceable by such person in the Court of Chancery of the
State of Delaware, if the Board of Directors or independent legal counsel denies
the claim, in whole or in part, or if no disposition of such claim is made

                                       17
<PAGE>
 
within ninety days.  The costs and expenses incurred by such person in
connection with successfully establishing his right to indemnification, in whole
or in part, in any such proceeding shall also be indemnified by the Corporation.

                          EXPENSES PAYABLE IN ADVANCE
                          ---------------------------

     Section 6.  Except as limited by Section 5 of this Article, expenses
incurred in defending a threatened or pending action, suit or proceeding shall
be paid by the Corporation in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of the
director or officer to repay such amount if it shall ultimately be determined
that he is not entitled to be indemnified by the Corporation as authorized in
this Article VIII.

                NON-EXCLUSIVITY AND SURVIVAL OF INDEMNIFICATION
                -----------------------------------------------

     Section 7.  The indemnification and advancement of expenses provided by or
granted pursuant to the other Sections of this Article VIII shall not be deemed
exclusive of any other rights to which any person seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, contract,
vote of stockholders or disinterested directors or otherwise, both as to action
in his official capacity and as to action in another capacity while holding such
office, it being the policy of the Corporation that indemnification of the
persons specified in Sections 1 and 2 of this Article VIII shall be made to the
fullest extent permitted by Delaware law. The provisions of this Article VIII
shall not be deemed to preclude the indemnification of any person who is not
specified in Sections 1 or 2 of this Article VIII but whom the Corporation has
the power or obligation to indemnify under the provisions of Delaware law or
otherwise. The indemnification and advancement of expenses provided by or
granted pursuant to this Article VIII shall, unless otherwise provided or
ratified, continue as to a person who has ceased to be a director or officer and
shall inure to the benefit of the heirs, executors and administrators of such
person.

                                   INSURANCE
                                   ---------

     Section 8.  The Corporation may purchase and maintain insurance on behalf
of any person who is or was a director, officer or employee of the Corporation,
or is or was serving at the request of the Corporation as a director, officer or
employee of another Corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such,
whether or not the Corporation would have the power or the obligation to
indemnify him against

                                       18
<PAGE>
 
such liability under the provisions of this Article VIII, or otherwise under
Delaware law.

             MEANING OF "CORPORATION" FOR PURPOSES OF ARTICLE VIII
             -----------------------------------------------------

     Section 9.  For purposes of this Article VIII, references to "the
Corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers or employees,
so that any person who is or was a director, officer or employee, of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
shall stand in the same position under the provisions of this Article VIII with
respect to the resulting or surviving corporation as he would have with respect
to such constituent corporation if its separate existence had continued.

     Section 10.  Subject to Section 5(b) hereof, the Corporation shall be
required to indemnify an indemnitee in connection with a proceeding (or part
thereof) initiated by such indemnitee only if the initiation of such proceeding
(or part thereof) by the indemnitee was authorized in writing by the Board of
Directors.

                                  ARTICLE IX
                                  ----------
                                  AMENDMENTS
                                  ----------

     Section 1.  These by-laws may be altered, amended or repealed or new by-
laws may be adopted by the stockholders or by the Board of Directors, when such
power is conferred upon the Board of Directors, by the Certificate of
Incorporation, at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal or adoption of new by-
laws be contained in the notice of such special meeting.

           --------------    --------

execution and delivery by the Agent and the Banks of this Amendment shall not be
deemed to create a course of dealing or otherwise obligate the Agent or the
Banks to forbear or execute similar amendments under the same or similar
circumstances in the future.

     6.   Miscellaneous.
          ------------- 

          (a)  Except as herein expressly amended, all terms, covenants and
provisions of the Credit Agreement are and shall remain in full force and effect

be delivered by any party thereto either in the form of an executed original or
an executed original sent by facsimile transmission to be followed promptly by
mailing of a hard copy original, and that receipt by the Agent of a facsimile
transmitted document purportedly bearing the signature of a Bank or the Company
shall bind such Bank or the Company, respectively, with the same force and
effect as the delivery of a hard copy original.  Any failure by the Agent to
receive the hard copy executed original of such document shall not diminish the
binding effect of receipt of the facsimile transmitted executed original of such
document of the party whose hard copy page was not received by the Agent.

          (e)  This Amendment, together with the Credit Agreement, contains the
entire agreement of the parties hereto with reference to the matters discussed
herein and therein.  This Amendment supersedes all prior drafts and
communications with respect thereto.  This Amendment may not be amended except
in accordance with the provisions of Section 10.01 of the Credit Agreement.

          (f)  If any term or provision of this Amendment shall be deemed
prohibited by or invalid under any applicable law, such provision shall be
invalidated without affecting the remaining provisions of this Amendment or the
Credit Agreement, respectively.

          (g)  The Company covenants to pay to or reimburse the Agent, upon
demand, for all costs and expenses (including allocated costs of in-house
counsel) incurred in connection with the development, preparation, negotiation,
execution and delivery of this Amendment.

          IN WITNESS WHEREOF, the parties hereto have executed and delivered
this Amendment as of the date first above written.

               Lessee under the Second Consent Agreement, including, without
               limitation, all amounts payable by Lessee under Section 5.2 of
               the Second Consent Agreement;

               (b)  agrees to indemnify, hold harmless and reimburse Lessor for
          (i) any damages that Lessor may incur as a result of Lessee's failure
          to perform any Obligations, including without limitation any damages
          Lessor may incur if Lessor sells or causes the Property to be sold to
          any Person following Lessee's failure to perform its obligations as
          set forth at Section 41 of the Amended Land Lease or Section 41 of the
          Amended Building Lease or as provided in the Consent Agreement or in
          the Second Consent Agreement, and (ii) any and all costs and expenses
          (including reasonable attorney's fees and expenses) incurred by Lessor

          and

               (c)  agrees, in the event of any termination of the Leases (or
          either of them), to make Lessor whole for, and to pay to Lessor
          immediately and without any deduction, discount or offset of any
          nature, any amount not paid to Lessor by the Lessee (for any reason
          and regardless of any defense or protection available to the Lessee
          with respect thereto) which 


                                      15
<PAGE>
 
          would have been paid to Lessor by the Lessee over the full term of the
          Leases and upon the expiration thereof had the Lessee fulfilled all of
          its obligations under the Leases including without limitation Lessee's
          obligations arising upon the expiration or termination of either of
          the Leases.

This is a Guaranty of performance and payment when due and not of collection.
Guarantor specifically agrees that it shall not be necessary or required that
Lessor exercise any right, assert any claim or demand or enforce any remedy
whatsoever against Lessee (or any other Person) before or as a condition to the
obligations of Guarantor hereunder.  Guarantor acknowledges that it has received
full and complete copies of and has approved the Consent Agreement, the Second
Consent Agreement, and the Leases.

          SECTION 2.2  Acceleration of Guaranty.  Guarantor agrees that, in the
                       ------------------------                                
event of the dissolution or insolvency of Lessee or Guarantor, or the inability
or failure of Lessee or Guarantor to pay debts as they become due, or an
assignment by Lessee or Guarantor for the benefit of creditors, or the
commencement of any case or proceeding in respect of Lessee or Guarantor under
any bankruptcy, insolvency or similar laws, and if such event shall occur at a
time when any of the Obligations of the Lessee may not then be due and payable,
Guarantor will pay to Lessor forthwith the full amount which would be payable
hereunder by Guarantor if all such Obligations were then due and payable.

          SECTION 2.3  Guaranty Absolute, etc.  This Guaranty shall in all
                       ----------------------                             
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment and performance, and shall remain in full force and effect until all
Obligations of Lessee have been paid in full or performed, and all obligations
of the Guarantor hereunder shall have been paid in full.  Guarantor guarantees
that the Obligations of Lessee will be paid and performed strictly in accordance
with the terms of the Lease or the Consent Agreement or Second Consent Agreement
under which they arise, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of Lessor with respect thereto.  The liability of Guarantor under this
Guaranty shall be absolute, unconditional and irrevocable irrespective of, and
Guarantor hereby waives:

               (a)  any defense based upon any lack of validity, legality or
          enforceability of either of the Leases;

               (b)  any defense based upon the failure of Lessor
  
                    (i)  to give notice to Guarantor of the occurrence of any
               default by Lessee under the terms of either of the Leases or the
               Consent Agreement or Second Consent Agreement,

                                      16
<PAGE>
 
                    (ii)  to assert any claim or demand or to enforce any right
               or remedy against Lessee or any other Person (including any other
               guarantor) under the provisions of either of the Leases or the
               Consent Agreement or Second Consent Agreement or otherwise, or

                    (iii)  to exercise any right or remedy against any other
               guarantor of, or collateral securing, any Obligations of the
               Lessee;

               (c)  any change in the time, manner or place of payment or
          performance of, or in any other term of, all or any of the Obligations
          of Lessee or any other extension, compromise or renewal of any
          Obligation of Lessee;

               (d)  any reduction, limitation, impairment or termination of the
          Obligations of Lessee for any reason, including any claim of waiver,
          release, surrender, alteration or compromise, and Lessor and Lessee
          shall not be subject to (and Guarantor hereby waives any right to or
          claim of) any defense or setoff, counterclaim, recoupment or
          termination whatsoever by reason of the invalidity, illegality,
          nongenuineness, irregularity, compromise, unenforceability of, or any
          other event or occurrence affecting, the Obligations of Lessee or
          otherwise;

               (e)  any limitation on amounts recoverable from Lessee under
          California Civil Code Section 1951.2 in the event of termination of
          either or both of the Leases;

               (f)  any amendment to, rescission, waiver, or other modification
          of, or any consent to departure from, any obligation, covenant or
          agreement set forth in either of the Leases or the Consent Agreement
          or the Second Consent Agreement (other than and to the extent that an
          amendment in writing executed by the Lessor by its terms specifically
          indicates that it is the intent of Lessor that such amendment reduce
          Guarantor's liability under this Guaranty);

               (g)  any addition, exchange, release, surrender or non-perfection
          of any collateral, or any amendment to or waiver or release or
          addition of, or consent to departure from, any other guaranty, held by
          Lessor securing any of the Obligations of Lessee; or

               (h)  any other circumstance which might otherwise constitute a
          defense available to, or a legal or equitable discharge of, Lessee,
          any surety or any guarantor.

Guarantor agrees that any release which may be given by Lessor to Lessee or any
other guarantor shall not release Guarantor.  Without limiting the foregoing,
Guarantor acknowledges that a breach of any 

                                      17
<PAGE>
 
representation, warranty or covenant of Guarantor hereunder will result in an
Event of Default under each of the Leases. Without limiting any other remedy
Lessor may have against Guarantor hereunder or against Lessee under the Leases,
Guarantor shall following the occurrence of any such breach under this Guaranty
and upon the written demand of Lessor purchase the Property as required pursuant
to Section 41 of the Amended Land Lease and Section 41 of the Amended Building
Lease.

          SECTION 2.4  Reinstatement, etc.  Guarantor agrees that this Guaranty
                       ------------------                                      
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment (in whole or in part) or performance of any of the Obligations
of Lessee is rescinded or must otherwise be restored by Lessor, upon the
insolvency, bankruptcy or reorganization of the Lessee or for any other reason,
all as though such payment or performance had not been made.

          SECTION 2.5  Waiver, etc.  (a) Guarantor hereby waives promptness,
                       -----------                                          
diligence, notice of acceptance and any other notice with respect to any of the
Obligations of Lessee and this Guaranty and any requirement that Lessor protect,
secure, respect or insure any Lien, or any property subject thereto, or exhaust
any right or take any action against Lessee or any other Person (including any
other Guarantor) or entity or any collateral securing the Obligations of Lessee.
Guarantor further waives (to the maximum extent permitted by law) any defense
arising by reason of any claim or defense based upon any limitation imposed on
amounts recoverable by Lessor under the Leases, including, if and to the extent
applicable, the provisions of California Civil Code Section 1951.2 or an
election of remedies by Lessor including, if and to the extent applicable, the
provisions of (S)(S)580d and 726 of the California Code of Civil Procedure or
any similar law of California or any other jurisdiction.

          (b)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR SPECIFICALLY WAIVES ANY POSSIBLE
CLAIM THAT GUARANTOR IS NOT A TRUE GUARANTOR OF THE LEASES (OR EITHER OF THEM),
WHETHER SUCH CLAIM IS BASED UPON ANY CONTENTION THAT THE LEASES (OR EITHER OF
THEM) ACTUALLY REPRESENT ONE OR MORE LOAN TRANSACTIONS, OR UPON ANY CONTENTION
THAT GUARANTOR ACTUALLY IS THE TRUE DEBTOR IF THE LEASES (OR EITHER OF THEM)
ACTUALLY REPRESENT ONE OR MORE LOAN TRANSACTIONS, OR UPON ANY OTHER SIMILAR OR
DISSIMILAR CONTENTION, OR UPON ANY COMBINATION THEREOF; AND GUARANTOR FURTHER
HEREBY WAIVES, TO THE MAXIMUM EXTENT SUCH WAIVER IS PERMITTED BY LAW, ANY AND
ALL DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF CALIFORNIA
CIVIL CODE (S)(S) 1951.2, 2808, 2809, 2810, 2815, 2819, 2820, 2821, 2838, 2839,
2845, 2848, 2849 AND 2850, TO THE EXTENT APPLICABLE, CALIFORNIA CODE OF CIVIL
PROCEDURE (S)(S) 580a, 580b, 580c, 580d AND 726, AND, TO THE EXTENT APPLICABLE,
CHAPTER 2 OF TITLE 14, PART IV OF THE CALIFORNIA CIVIL CODE.

          (c) Without limiting the generality of any other waiver or other
provision set forth in this Guaranty, Guarantor authorizes Lessor at its sole
option, without notice or demand and without affecting the liability of the
Guarantor hereunder, to release and reconvey (with or without receipt of any
consideration) any Lien against any or all collateral for the Obligations of
Lessee, and to exercise all powers of sale in the Leases and to foreclose any or
all deeds of trust, mortgages or other instruments or agreements by judicial or
non-judicial sale, all without affecting the liability of the Guarantor
hereunder.  Guarantor expressly waives any defense to the recovery by Lessor
from Guarantor of any deficiency after a non-judicial sale, including, without
limitation, any defense arising as a result of any election of remedies by
Lessor which limits or destroys such Guarantor's subrogation rights or such
Guarantor's right to proceed against Lessee for reimbursement (including,
without limitation, any election by Lessor to exercise its rights under a power
of sale in or any instruments securing the Obligations of Lessee under the
Leases, any deed of trust or mortgage and any consequential loss by Guarantor of
the right to recover any deficiency from the Lessee).  Guarantor waives all
rights and defenses arising out of an election of remedies by the Lessor, even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a guaranteed obligation, has destroyed the Guarantor's rights of
subrogation and reimbursement against the Lessee by the operation of Section
580d of the Code of Civil Procedure or otherwise.  Guarantor waives any right to
receive notice of any judicial or non-judicial sale or the sale or foreclosure
of any real property, and the failure of the Guarantor to receive such notice
shall not impair or affect the Guarantor's liability hereunder.  Guarantor
warrants and agrees that each of the acknowledgements and waivers set forth in
this Guaranty is made with full knowledge of its significance and consequences
and that, under the circumstances, the waivers are reasonable and not contrary
to public policy or law.  If, despite the foregoing, any of such waivers are
determined to be contrary to any applicable law or public policy, such waivers
shall be effective only to the maximum extent permitted by law.

          SECTION 2.6  Subrogation.  Guarantor hereby disclaims, releases and
                       -----------                                           
waives forever any subrogation claims or rights it would otherwise have or be
entitled to under this Guaranty or pursuant to applicable law as a result of any
payment made by Guarantor hereunder or otherwise.  Any amount paid to Guarantor
on account of any such subrogation rights shall be held in trust for the benefit
of Lessor and shall immediately be paid to Lessor and credited and applied
against the Obligations of Lessee, whether matured or unmatured, in accordance
with the terms of either of the Leases.  In furtherance of the foregoing,
Guarantor shall refrain from taking any action or commencing any proceeding
against the Lessee (or its successors or assigns, whether in connection with a

                                      19
<PAGE>
 
bankruptcy proceeding or otherwise) to recover any amounts in the respect of
payments made under this Guaranty to Lessor.

receipt of the facsimile transmitted executed original of such document of the

          (e)  This Amendment, together with Term Loan Agreement, contains the
entire and exclusive agreement of the parties hereto with reference to the

and communications with respect thereto. This Amendment may not be amended
except in accordance with the provisions of Section 10.01 of the Term Loan
Agreement.

          (f)  If any term or provision of this Amendment shall be deemed
prohibited by or invalid under any applicable law, such provision shall be
invalidated without affecting the remaining provisions of this Amendment or the
Term Loan Agreement, respectively.

          (g)  The Company covenants to pay to or reimburse the Administrative
Agent and the Banks, upon demand, for all costs and expenses (including
allocated costs of in-house counsel) incurred in connection with the
development, preparation, negotiation, execution and delivery of this Amendment.
