ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a
Delaware corporation to indemnify any persons who are, or are threatened to be
made, parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other
than an action by or in the right of such corporation), by reason of the fact
that such person is or was an officer or director of such corporation or is or
was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may
include expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer or
director acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the corporation, and, in the
case of criminal proceedings, had no reasonable cause to believe his or her
conduct was illegal. A Delaware corporation may indemnify officers and
directors against expenses (including attorneys' fees) in connection with the
defense or settlement of an action by or in the right of the corporation under
the same conditions, except that no indemnification is permitted without
judicial approval if the officer or director is adjudged to be liable to the
corporation. Where an officer or director is successful on the merits or
otherwise in the defense of any action referred to above, the corporation must
indemnify him or her against expenses which such officer or director actually
and reasonably incurred. The Restated Certificate of Incorporation of the
Company provides for indemnification of the officers and directors of the
Company to the full extent permitted by applicable law.
 
  In accordance with Delaware law, the Restated Certificate of Incorporation
of the Company contains a provision to limit the personal liability of
directors of the Company for violations of their fiduciary duty. This
provision eliminates each director's liability to the Company or its
stockholders for monetary damages except (i) for any breach of the director's
duty of loyalty to the Company or its stockholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, providing for liability
of directors for unlawful payment of dividends or unlawful stock
 
                                     II-1
<PAGE>
 
purchases or redemptions or (iv) for any transaction from which a director
derived an improper personal benefit. The effect of this provision is to
eliminate the personal liability of directors for monetary damages for actions
involving a breach of their fiduciary duty of care, including any such actions
involving gross negligence.
 
  Pursuant to the underwriting agreement between the Company, Silicon Graphics
and the underwriters filed as an exhibit to this Registration Statement, the
underwriters a party thereto have agreed to indemnify each officer and
director of the Company and Silicon Graphics, Inc. and each person, if any,
who controls the Company and Silicon Graphics, Inc. within the meaning of the
Securities Act of 1933, as amended (the "Securities Act"), against certain
liabilities, including liabilities under said Act.

  (b) FINANCIAL STATEMENT SCHEDULES
 
  Schedules have been omitted because the information required to be set forth

ITEM 17. UNDERTAKINGS
 
  (a) The Registrant hereby undertakes to provide to the underwriter at the
closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.
 
  (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than payment by the Registrant
of expenses incurred or paid by a director, officer or controlling person of
the Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
 
  (c) The undersigned Registrant hereby undertakes that:
 
    (i) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Company pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective; and
 
    (ii) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at the time shall be
  deemed to be the initial bona fide offering thereof.

regardless of when or where such Liabilities arose or arise, or whether the
facts on which they are based occurred prior to or subsequent to the date
hereof, regardless of where or against whom such Liabilities are asserted or
determined (including any Company Liabilities arising out of claims made by
Silicon Graphics' or the Company's respective directors, officers, employees,
agents or Affiliates) or whether asserted or determined prior to the date
hereof, and regardless of whether arising from or alleged to arise from

      Section 2.3. Transfers Not Effected On or Prior to the Closing Date.  To
                   ------------------------------------------------------     
the extent any transfers contemplated by this Article II shall not have been
fully effected on or prior to the Closing Date, Silicon Graphics and the Company
shall cooperate to effect such transfers as promptly as possible following the
Closing Date.  Nothing herein shall be deemed to require the transfer of any
assets or the assignment or assumption of any Liabilities that by their terms or
by operation of law cannot be so transferred, assigned or assumed; provided,
however, that any such asset shall be deemed a Company Asset for purposes of
determining whether any Liability is a Company Liability; and provided, further,
that Silicon Graphics and the Company and their respective Affiliates shall
cooperate in seeking to obtain any necessary Consents for the transfer of all
assets and the assignment or assumption of all Liabilities as contemplated by
this Article II.  In the event that any transfer of assets or assignment or
assumption of Liabilities contemplated by this Article II has not been
consummated effective as of the Closing Date, (i) the party retaining such
assets shall thereafter hold such assets in trust for the use and benefit of the
party entitled thereto (at the expense of the party entitled thereto); and (ii)
the party retaining such Liabilities shall thereafter hold such Liabilities for
the account of the party assuming such Liability or to whom such Liability is to
be assigned pursuant hereto, and in each such case shall take such other actions
as may be reasonably required in order to place the parties, insofar as
reasonably possible, in the same position as would have existed had such asset
been transferred, or such Liability been assigned or assumed as contemplated
hereby.  As and when any such asset or Liability becomes transferable,
assignable or assumable, as the case may be, such transfer, assignment or
assumption, as the case may be, shall be effected forthwith.  Silicon Graphics
and the Company agree that, as of the Closing Date, each party hereto shall be
deemed to have acquired complete and sole beneficial ownership over all of the
assets, together with all of the rights, powers and privileges incidental
thereto, that such party is entitled to acquire pursuant to the terms of this
Agreement.

                   ------------------------------------------                  
parties hereto understands and agrees that no party hereto is, in this
Agreement, any Ancillary Agreement or any other agreement or document
contemplated by this Agreement, any Ancillary Agreement or otherwise,
representing or warranting in any way as to the value or freedom from
encumbrance of, or any other matter concerning, any assets of such party, or as
to the legal sufficiency to convey title to an asset transferred pursuant to
this Agreement or any Ancillary Agreement, including, without limitation, any
conveyancing or assumption instruments.  It is also agreed and 

                                       10
<PAGE>
 
understood that there are no warranties whatsoever, express or implied, given by
either party to this Agreement, as to the condition, quality, merchantability or
fitness of any of the assets, businesses or other rights transferred or retained
by the parties, as the case may be, and all such assets, businesses and other
rights shall be "as is, where is" and "with all faults" (provided that the
absence of warranties given by the parties shall not negate the allocation of
Liabilities under this Agreement and shall have no effect on any manufacturers,
sellers, or other third party warranties that are intended to be transferred
with such assets), and the Company shall bear the economic and legal risks that
any conveyance shall prove to be insufficient to vest in it good and marketable
title, free and clear of any security interest, pledge, lien, charge, claim,
option, right to acquire, covenant, condition, restriction on transfer or other
encumbrance of any nature whatsoever.

     (b) Each party hereto understands and agrees that no party hereto is, in
this Agreement, any Ancillary Agreement or any other agreement or document
contemplated by this Agreement, any Ancillary Agreement or otherwise,
representing or warranting in any way that the obtaining of any Consents, the
execution and delivery of any amendatory agreements and the taking of any
filings or applications contemplated by this Agreement will satisfy the
provisions of any or all applicable laws or judgments or other instruments or
agreements relating to such assets.

     Notwithstanding the foregoing, the parties shall use their good faith
efforts to obtain all Consents (including such Consents as may be required by
any Governmental Authority), to enter into all reasonable amendatory agreements
and to make all filings and applications contemplated by this Agreement, and
shall take all such further actions as shall be deemed reasonably necessary to
preserve for each of Silicon Graphics and the Company, to the greatest extent
reasonably feasible, consistent with this Agreement, the economic and
operational benefits of the allocation of assets and liabilities provided for in
this Agreement.  In case at any time after the Closing Date any further action
is necessary or desirable to carry out the purposes of this Agreement, the
proper officers and directors of each party to this Agreement shall take all
such necessary or desirable action, provided that any financial cost shall be
borne by the party receiving the benefit of the action.

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

Assets pursuant to Section 2.1 of this Agreement and the assignment and
assumption of the Company Liabilities pursuant to Section 2.2 of this Agreement,
simultaneously with the execution and delivery hereof or as promptly as
practicable thereafter, (i) Silicon Graphics shall execute and deliver such
bills of sale, deeds, stock powers, certificates of title, assignments of
contracts and other instruments or transfer, conveyance and assignment as and to
the extent necessary to evidence the transfer, conveyance and assignment of all
of Silicon Graphics' right, title and interest in and to the Company Assets to
the Company and (ii) the Company shall execute and deliver to Silicon Graphics
such bills of sale, certificates of title, assumptions of contracts and other
instruments or assumption as may be necessary to evidence the valid and
effective assumption of the Company Liabilities by the Company.

4.1 hereof, the Company, on the one hand, and Silicon Graphics, on the other
hand, hereby terminate, effective as of the Closing Date, any and all

such terminated agreement, arrangement, commitment or understanding (including
any provision thereof which purports to survive termination) shall be of any
further force or effect after the Closing Date (or, to the extent contemplated
by the proviso to the immediately preceding sentence, after the effective date
of the applicable Ancillary Agreement).  Each party shall, at the reasonable
request of the other party, take, or cause to be taken, such other actions as

following agreements, arrangements, commitments or understandings (or any of the
provisions thereof): (i) this Agreement and the Ancillary Agreements (and each

understandings to which any Person other than the parties hereto or their
respective Affiliates is a party, (iii) any intercompany accounts payable or
accounts receivable accrued as of the Closing Date that are reflected in the
books and records of the parties or otherwise documented in writing in

     (k) Silicon Graphics shall have been released from any liabilities,
guarantees or other obligations with respect to any indebtedness or otherwise of
the Company or its subsidiaries; provided, that the satisfaction of such
conditions shall not create any obligation on the part of Silicon Graphics to
effect the Separation or in any way limit Silicon Graphics' power of termination
set forth in Section 8.1 or alter the consequences of any such termination from
those specified in such Section;

     (l) Silicon Graphics shall be satisfied in its sole discretion that it will
own at least 80.1% of the outstanding Common Stock following the Initial Public

consultants of the Company, and all other conditions to permit any subsequent
distribution of the Common Stock to Silicon Graphics' shareholders to qualify as
a tax-free distribution to Silicon Graphics, the Company and Silicon Graphics'
shareholders shall, to the extent applicable as of the time of the Initial
Public Offering, be satisfied and there shall be no event or condition that is
likely to cause any of such conditions not to be satisfied as of the time of the
Separation or thereafter;

     (m) Such other actions as the parties hereto may, based upon the advice of
counsel, reasonably request to be taken prior to the Separation and the Initial
Public Offering in order to assure the successful completion of the Separation
and the Initial Public Offering and the other transactions contemplated by this

          (v) Any Liability the release of which would result in the release of
     any Person other than a Person released pursuant to this Section 4.1;
     provided that the parties agree not to bring suit or permit any of their
     subsidiaries to bring suit against any Person with respect to any Liability

any other Person to pay, perform or otherwise promptly discharge any Liability
of the SGI Group other than the Company Liabilities in accordance with its

      Section 4.4.  Notice and Payment of Claims.  If any SGI Indemnitee or
                    ----------------------------                           
Company Indemnitee (the "Indemnified Party") determines that it is or may be
                         -----------------                                  
entitled to indemnification under this Article IV (other than in connection with
any Action subject to Section 4.5), the Indemnified Party shall deliver to the
person from whom such indemnification is sought (the "Indemnifying Party"), a
                                                      ------------------     
written notice specifying, to the extent reasonably practicable, the basis for
its claim for indemnification and the amount for which the Indemnified Party
reasonably believes it is entitled to be indemnified.  After the Indemnifying
Party shall have been notified of the amount for which the Indemnified Party
seeks indemnification, the Indemnifying Party shall, within 30 days after
receipt of such notice, either (i) pay the Indemnified Party such amount in cash
or other immediately available funds (or reach agreement with the Indemnified
Party as to a mutually agreeable alternative payment schedule) or (ii) object to
the claim for indemnification or the amount thereof by giving the Indemnified
Party written notice setting forth the grounds therefor.  Any objection shall be
resolved in accordance with Article VII.  If the Indemnifying Party does not
give such notice within such 30 day period, the Indemnifying Party shall be
deemed to have acknowledged its liability for such claim and the Indemnified
Party may exercise any and all of its rights under applicable law to collect
such amount.

      Section 4.5.  Notice and Defense of Third-Party Claims.  Promptly
                    ----------------------------------------           
following the earlier of (A) receipt of written notice of the commencement by a
third party of any Action against or otherwise involving any Indemnified Party
or (B) receipt of written information from a third party alleging the existence
of a claim against an Indemnified Party, in either case, with respect to which
indemnification may be sought pursuant to this Agreement (a "Third-Party
                                                             -----------
Claim"), the Indemnified Party shall give the Indemnifying Party prompt written
notice thereof.  Failure of the Indemnified Party to give notice as provided in
this Section 4.5 shall not relieve the Indemnifying Party of its obligations
under this Agreement, except to the extent that the Indemnifying Party is
prejudiced by such failure to give notice.  Such notice shall describe the
Third-Party Claim in reasonable detail.

     (a) Within 30 days after receipt of such notice, the Indemnifying Party may
by giving written notice thereof to the Indemnified Party, (i) elect to assume
the defense of such Third-Party Claim at its sole cost and expense or (ii)
object to the claim of indemnification for such Third-Party Claim setting forth
the grounds therefor.  Any objection shall be resolved in accordance with
Article VII.  If the Indemnifying Party does not within such 30 day period give
the Indemnified Party such notice, the Indemnifying Party shall be deemed to
have acknowledged its liability for such Third-Party Claim.

     (b) Any defense of a Third-Party Claim as to which the Indemnifying Party
has elected to assume the defense shall be conducted by counsel employed by the
Indemnifying Party and reasonably satisfactory to Silicon Graphics in the case
of SGI Indemnitees and the Company in the case of Company Indemnitees.  The
Indemnified Party shall have the right to participate in such proceedings and to
be represented by counsel of its own choosing at the Indemnified Party's sole
cost and expense; provided that if the defendants or parties against which
relief is sought in any such claim include both the Indemnifying Party and one
or more Indemnified Parties and, in the reasonable judgment of Silicon Graphics
in the case of SGI Indemnitees and the Company in the case of Company
Indemnitees, a conflict of interest between such Indemnified Parties and such
Indemnifying Party exists in respect of such claim, such Indemnified Parties
shall have the right to employ one firm of counsel selected by Silicon Graphics
for SGI Indemnitees or the Company for Company Indemnitees and in that event the
reasonable fees and expenses of such separate counsel (but not more than one
separate counsel reasonably satisfactory to the Indemnifying Party) shall be
paid by such Indemnifying Party.

     (c) If the Indemnifying Party assumes the defense of a Third-Party Claim,
the Indemnifying Party may settle or compromise the claim without the prior
written consent of the Indemnified Party; provided that without the prior
written consent of Silicon Graphics in the case of SGI Indemnitees and the
Company in the case of Company Indemnitees, the Indemnifying Party may not agree
to any such settlement unless as a condition to such settlement the Indemnified
Party receives a written release from any and all liability relating to such
Third-Party Claim and such settlement or compromise does not include any remedy
or relief to be applied to or against the Indemnified Party, other than monetary
damages for which the Indemnifying Party shall be responsible hereunder.

                                       19
<PAGE>
 
     (d) If the Indemnifying Party does not assume the defense  of a Third-Party
Claim for which it has acknowledged liability for indemnification under this
Article IV, Silicon Graphics in the case of SGI Indemnitees and the Company in
the case of Company Indemnitees may pursue the defense of such Third-Party Claim
and choose one firm of counsel in connection therewith. The Indemnifying Party
is required to reimburse Silicon Graphics or the Company, as the case may be, on
a current basis for its reasonable expenses of investigation, reasonable
attorney's fees and reasonable out-of-pocket expenses incurred by Silicon
Graphics in the case of SGI Indemnitees and the Company in the case of Company
Indemnitees in defending against such Third-Party Claim and the Indemnifying
Party shall be bound by the result obtained with respect thereto, provided that
the Indemnifying Party shall not be liable for any settlement  effected without
the consent of the Indemnifying Party, which consent shall not be unreasonably
withheld.

     (e) The Indemnifying Party shall pay to the Indemnified Party in cash the
amount for which the Indemnified Party is entitled to be indemnified (if any) no
later than the later of (i) the date on which the Indemnified Party makes any
payment in satisfaction (partial or otherwise) of the Third-Party Claim or (ii)
the date on which such Indemnifying Party's objection, if any, to its
responsibility for indemnification under this Article IV has been resolved
pursuant to Article VII or by settlement or compromise or the final
nonappealable judgment of a court of competent jurisdiction.

      Section 4.6.  Insurance  Proceeds.  The  amount  that  any Indemnifying
                    -------------------                                      
Party is or may be required to pay to any Indemnified Party pursuant to this
Article IV shall be reduced (including, without limitation, retroactively) by
any insurance proceeds or other amounts actually recovered by or on behalf of
such Indemnified Parties in reduction of the related Liability.  If an
Indemnified Party shall have received the payment required by this Agreement
from an Indemnifying Party in respect of a Liability and shall subsequently
actually receive insurance proceeds, or other amounts in respect of such
Liability as specified above, then such Indemnified Party shall pay to such
Indemnifying Party a sum equal to the amount of such insurance proceeds or other
amounts actually received after deducting therefrom all of the Indemnifying
Party's costs and expenses associated with such Liability.

      Section 4.7.  Contribution.  If the indemnification provided for in this
                    ------------                                              
Article IV is unavailable to an Indemnified Party in respect of any Liability
arising out of or related to information contained in or omitted from the
Registration Statement, then the Company Indemnitees, or SGI Indemnitees, as the
case may be, in lieu of indemnifying the SGI Indemnitees or Company Indemnitees,
as the case may be, shall contribute to the amount paid or payable by the SGI
Indemnitees or SGI Indemnitees, as the case may be, as a result of such
Liability in such proportion as is appropriate to reflect the relative fault of
the Company, on the one hand, and Silicon Graphics, on the other hand, in
connection with the statements or omissions which resulted in such Liability.
The relative fault of the Company Indemnitees on the one hand and of the SGI
Indemnitees on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the

                                       20
<PAGE>
 
omission or alleged omission to state a material fact relates to information
concerning the Company on the one hand or Silicon Graphics on the other hand.

      Section 4.8.  Subrogation.  In the event of payment by an Indemnifying
                    -----------                                             
Party to any Indemnified Party in connection with any Third-Party Claim, such
Indemnifying Party shall be subrogated to and shall stand in the first place of
such Indemnified Party as to any events or circumstances in respect of which
such Indemnified Party may have any right or claim relating to such Third-Party
Claim.  Such Indemnified Party shall cooperate with such Indemnifying Party in a
reasonable manner, and at the cost and expense of such Indemnifying Party, in
prosecuting any subrogated right or claim.

      Section 4.9.  No Third-Party Beneficiaries.  This Article IV shall inure
                    ----------------------------                              
to the benefit of, and be enforceable by Silicon Graphics, the SGI Indemnitees,
the Company and the Company Indemnitees and their respective successors and
permitted assigns.  The indemnification provided for by this Article IV shall
not inure to the benefit of any other third party or parties and shall not
relieve any insurer who would otherwise be obligated to pay any claim of the
responsibility with respect thereto or, solely by virtue of the indemnification
provisions hereof, provide any subrogation rights with respect thereto and each
party agrees to waive such rights against the other to the fullest extent
permitted.

1.   Section 4.10.  Remedies Cumulative.  The remedies provided in this Article
                    -------------------                                        
     IV shall be cumulative and shall not preclude assertion by any Indemnified
     Party of any other rights or the seeking of any and all other remedies
     against an Indemnifying Party.  The procedures set forth in this Article
     IV, however, shall be the exclusive procedures governing any indemnity
     action brought under this Article IV or otherwise relating to Liabilities.

     Section 4.11.  Survival of Indemnities.  The rights and obligations of
                    -----------------------                                
each of Silicon Graphics and the Company and their respective Indemnitees under
this Article IV shall survive the sale or other transfer by it of any assets or
businesses or the assignment by it of any Liabilities.

     Section 4.12.  After-Tax Indemnification Payments.  Except as otherwise
                    ----------------------------------                      
expressly provided herein or in an Ancillary Agreement, indemnification payments
made by either party under this Article shall give effect to, and be reduced by
the value of, any and all applicable deductions, losses, credits, offsets or
other items for Federal, state or other tax purposes attributable to the payment
of the indemnified liability by the Indemnified Party.

take all necessary action to release Silicon Graphics from any liabilities,
guarantees, or other obligations with respect to indebtedness or other
obligations of the Company or its subsidiaries, other than the obligations
hereunder or under the Ancillary Agreements, provided, that the satisfaction of

termination from those specified in such Section.

Graphics and its subsidiaries shall retain with respect to any Covered Claims as

     (c) Administration and Procedure.  (i) The Company or a subsidiary of the
Company, as appropriate, shall be responsible for the claims administration and
financial administration of all Policies for Covered Claims relating to the
assets, ownership or operation prior to the Closing Date of the Company
Business; provided, however, that such retention by the Company of the Policies
and the responsibility for claims administration and financial administration of
the Policies are in no way intended to limit, inhibit or preclude any right to
insurance coverage for any Covered Claims under the Policies by Silicon
Graphics.  The Company or a subsidiary thereof, as appropriate, shall be
responsible for all administrative and financial matters relating to insurance
policies established and maintained by the Company and its subsidiaries for
claims relating to any period on or after the Closing Date involving the Company
or any of its subsidiaries.

          (ii) The Company shall notify Silicon Graphics of any Covered Claim
     relating to the Company or a subsidiary thereof under one or more of the
     Policies relating to a period prior to the Closing Date, and the Company
     agrees to cooperate and coordinate with Silicon Graphics concerning any
     strategy Silicon Graphics may reasonably elect to pursue to secure coverage
     and payment for such Covered Claim by the appropriate insurance carrier.
     Notwithstanding anything contained herein, in any other agreement or
     applicable Policy or any understanding to the contrary, the Company or an
     appropriate subsidiary thereof assumes responsibility for, and shall pay to
     the appropriate insurance carriers or otherwise, any premiums,
     retrospectively-rated premiums, defense costs, indemnity payments,
     deductibles, retentions or other charges, as appropriate (collectively,

     liabilities, losses, claims, actions or occurrences, whenever arising or
     becoming known, involving or relating to any of the assets, businesses,
     operations or 

                                       23
<PAGE>
 
     liabilities of the Company or any of its subsidiaries, to the extent set
     forth in Section 5.5(a) and any such charges that relate to the period
     after the Closing Date. To the extent that the terms of any applicable
     Policy provide that Silicon Graphics or a subsidiary thereof, as
     appropriate, shall have an obligation to pay or guarantee the payment of
     any Insurance Charges, Silicon Graphics or such subsidiary shall be
     entitled to demand that the Company or a subsidiary thereof make such
     payment directly to the person or entity entitled thereto. In connection
     with any such demand, Silicon Graphics shall submit to the Company or a
     subsidiary thereof a copy of any invoice received by Silicon Graphics or a
     subsidiary pertaining to such Insurance Charges, together with appropriate
     supporting documentation, if available. In the event that the Company or
     its subsidiary fails to pay any Insurance Charges when due and payable,
     whether at the request of the party entitled to payment or upon demand by
     Silicon Graphics or a subsidiary of Silicon Graphics, Silicon Graphics or a
     subsidiary of Silicon Graphics may (but shall not be required to) pay such
     Insurance Charges for and on behalf of the Company or its subsidiary and,
     thereafter, the Company or its subsidiary shall forthwith reimburse Silicon
     Graphics or such subsidiary of Silicon Graphics for such payment.

and mediation set forth in this Article VII shall apply to all disputes,
controversies or claims (whether sounding in contract, tort or otherwise) that
may arise out of or relate to, or arise under or in connection with this
Agreement or any Ancillary Agreement, or the transactions contemplated hereby or
thereby (including all actions taken in furtherance of the transactions
contemplated hereby or thereby on or prior to the date hereof), or the
commercial or economic relationship of the parties relating hereto or thereto,
between Silicon Graphics and its subsidiaries and the Company and its
subsidiaries.

      Section 7.2.  Escalation.  It is the intent of the parties to use their
                    ----------                                               
respective reasonable best efforts to resolve expeditiously any dispute,
controversy or claim between or among them with respect to the matters covered
hereby that may arise from time to time on a mutually acceptable negotiated
basis.  In furtherance of the foregoing, any party involved in a dispute,
controversy or claim may deliver a notice (an "Escalation Notice") demanding an
                                               -----------------               
in person meeting involving representatives of the parties at a senior level of
management of the parties (or if the parties agree, of the appropriate strategic
business unit or division within such entity).  A copy of any such Escalation
Notice shall be given to the General Counsel, or like officer or official, of
each party involved in the dispute, controversy or claim (which copy shall state
that it is an Escalation Notice pursuant to this Agreement). Any agenda,
location or procedures for such discussions or negotiations between the parties
may be established by the parties from time to time; provided, however, that the
parties shall use their reasonable best efforts to meet within 30 days of the
Escalation Notice.

      Section 7.3.  Demand for Mediation.  At any time after the first to occur
                    --------------------

Escalation Notice or (ii) 90 days after the delivery of an Escalation Notice (as
applicable, the "Mediation Demand Date"), any party involved in the dispute,
                 ---------------------                                      
controversy or claim (regardless of whether such party delivered the Escalation
Notice) may make a written demand (the "Mediation Demand Notice") that the
                                        -----------------------           
dispute be submitted to mediation.  Any opinion expressed by the mediator shall
not be binding on the parties, nor shall any opinion expressed by the mediator
be admissible in any subsequent proceedings.  The mediator may be chosen from a
list of mediators previously selected by the parties or by other agreement of
the parties.  Costs of the mediation shall be borne equally by the parties
involved in the matter, except that each party shall be responsible for its own
attorney's fees and other costs and expenses.  The site of the mediation shall
be Mountain View, California, unless otherwise agreed by the parties.  No party
may assert that the failure to resolve any matter during any discussions or
negotiations, the course of conduct during the discussions or negotiations or
the failure to agree on a mutually acceptable time, agenda, location or
procedures for the meeting, in each case, as contemplated by Section 7.2, is a
prerequisite to a demand for meditation under Section 7.3.

     Section 7.4.  Certain Additional Matters.  (a)  Either party may apply to
                   --------------------------                                 
any court having jurisdiction and seek injunctive relief so as to maintain the
status quo until such time as the mediation is concluded or the controversy is
otherwise resolved.

     (b)  Except as required by law, the parties shall hold, and shall cause
their respective officers, directors, employees, agents and other
representatives to hold, the existence, content and result of mediation in
confidence in accordance with the provisions of Article VI. Each of the parties
shall request that any mediator comply with such confidentiality requirement.

     (c)  Notwithstanding anything herein to the contrary, in the event that any
party determines in good faith that the amount in controversy in any dispute,
controversy or claim (or any series of related disputes, controversies or
claims) under this Agreement or any 

                                       27
<PAGE>
 
Ancillary Agreement is, or is reasonably likely to be, in excess of $30 million,
the provisions of Section 7.3 shall not apply and any party may elect, in lieu
of mediation, to commence an Action with respect to such dispute, controversy or
claim (or such series of related disputes, controversies or claims) in any court
of competent jurisdiction.

     Section 7.5.  Continuity of Service and Performance.  Unless otherwise
                   -------------------------------------                   
agreed in writing, the parties will continue to provide service and honor all
other commitments under this Agreement and each Ancillary Agreement during the
course of dispute resolution pursuant to the provisions of this Article VII with
respect to all matters not subject to such dispute, controversy or claim.

          ----------                                                       
          relationship with the other party, it has and will have access to
          certain information and materials that is confidential and of
          substantial value to the other party ("Confidential Information"),
          which value would be impaired if such information were disclosed to
          third parties.  Each party agrees that, except as specifically
          authorized hereunder, it will not use in any way for its own account
          or the account of any third party, nor disclose to any third party,
          any such Confidential Information, and will take every reasonable

<PAGE>
 
          confidentiality of such information which shall in no event be less
          than the industry standard and shall include: entering into non-
          disclosure agreements with third parties prior to disclosing any
          Confidential Information that the other party grants permission to

          only, password protect servers and files that contain Confidential
          Information, restricting access to confidential information by third
          parties (including contractors), storing Confidential Information in
          locked files or rooms. Upon request by a party, the other party will
          advise the requesting party whether or not it considers any particular
          information or materials to be Confidential Information.

     6.2. Transfer of Information.  MIPS acknowledges that (i) all technical
          -----------------------                                           
          information, know-how, software, or other materials (excluding non-
          technical business materials) transferred by MIPS from SGI are listed
          on Exhibits to this Agreement,  (ii) information in electronic format
          was transferred to clean servers and only information set forth in

          access to the SGI Group's servers as of the Closing Date or as
          mutually agreed.  MIPS agrees to promptly return or destroy all copies
          of any unauthorized SGI Confidential Information in its possession or
          control.  MIPS agrees that SGI, during the Capture Period, shall have
          the right to audit MIPS's servers, files, and premises to ensure
          compliance with this Section 6.  In the event SGI discovers
          unauthorized use of SGI Confidential Information, MIPS shall pay the
          cost of the audit and shall use its best efforts to correct such
          unauthorized use, including without limitation, obtaining a license to
          use such information, destroying or returning such information, and
          ceasing to license or distribute products or materials that contain
          such information.

     6.3. Exceptions.  The foregoing restrictions will not apply to information
          ----------                                                           
          that (i) has become publicly known through no wrongful act of the
          receiving party; (ii) has been rightfully received from a third party
          authorized to make such disclosure without restriction; (iii) has been
          independently developed by the receiving party after the Closing Date
          of this Agreement; (iv) has been approved for release by written
          authorization of the disclosing party, or (v) is required by law or
          regulation to be disclosed; provided, however, that the receiving has
          provided written notice to the disclosing party promptly to enable
          disclosing party to seek a protective order or otherwise prevent
          disclosure of Confidential Information.

     6.4. Term.  The obligations of each party pursuant to this Section 6 with
          ----                                                                
          respect to Confidential Information shall continue in full force and
          effect for a period of ten (10) years after the Effective Date of this
          Agreement; provided that if the disclosing party requests an
          additional ten (10) year period for maintaining the confidentiality of
          any specified Confidential Information, the obligations under

                                       9
<PAGE>
 
          this Section 6 shall continue with respect to such Confidential
          Information for an additional ten (10) years.

          -----------------                                                    
          its obligations under this Section 6 may cause irreparable harm and
          significant injury to the disclosing party to an extent that may be
          extremely difficult to measure.  Accordingly, the receiving party
          agrees that the disclosing party will have, in addition to any other
          rights or remedies available to it at law or in equity, the right to
          seek injunctive relief to enjoin any breach of this Section 6.

               (h)  The other party admits in writing its inability to pay its
                    debts as they become due.

          7.2.2. Termination for Breach. If MIPS materially breaches any
                 ----------------------
                 material term or condition of this Agreement, then upon forty-
                 five (45) days written notice to MIPS specifying the default
                 ("Notice of Default"), SGI may terminate or suspend this
                 Agreement, without liability, unless the default reasonably
                 requires more than forty-five (45) days to correct and MIPS has
                 begun substantial corrective actions to remedy the default and
                 is diligently pursuing such actions, in which event, MIPS shall
                 have so much time as is reasonably necessary to cure such
                 default.

     7.3. Effect of Termination.  (a)  In the event of termination pursuant to
          ---------------------                                               
          Section 7.2 above, the party terminating the Agreement pursuant to
          Section 7.2 above shall retain all licenses and rights granted to it
          under this Agreement for the term of the Agreement, and all licenses
          granted to the other party shall terminate subject to any sublicenses
          previously granted, and (b) the following sections shall survive any
          termination or expiration of the Agreement: Sections 2.1, 2.4, 5, 6,
          7, 8, 9 and 10.

8.   ASSIGNMENT AND CHANGE OF CONTROL

     8.1. Assignment.  This Agreement is personal to MIPS and the Agreement or
          ----------                                                          
          any right or obligation under it may not be assigned by MIPS without
          the prior written consent of SGI (except for a Change of Control as
          defined below).  SGI may freely assign this Agreement provided that in
          such case, the licenses granted to SGI under Section 2.2 above shall
          be limited to the SGI Field of Use unless otherwise agreed to by MIPS
          in writing.  Any purported assignment, except as explicitly permitted
          herein, shall be deemed a breach of this Agreement and shall be null
          and void.  This Agreement shall be binding upon and inure to the
          benefit of the parties and their permitted successors and assigns.

     8.2. Change of Control.
          ----------------- 

          8.2.1. MIPS.  Except where SGI's sale of MIPS capital stock to a
                 ----                                                     
                 third party results in a Change of Control, in the event more
                 than fifty (50%) of the outstanding shares or securities
                 (representing the right to vote for the election of directors
                 or other managing authority) of MIPS becomes owned or
                 controlled directly or indirectly by a third party ("Change of
                 Control"), MIPS shall promptly give notice to SGI of such
                 Change of Control. Upon such Change of Control the licenses
                 granted to MIPS pursuant to Section 3 above shall immediately
                 terminate except that in the event after such Change of
                 Control, MIPS is kept by the acquirer as an intact and
                 independent business unit recognizable as the same business
                 unit that existed prior to the Change of Control, then: (i)
                 MIPS's licenses shall be restricted to the MIPS business unit
                 only and not the acquirer's 

                                       11
<PAGE>
 
                 other business units, and (ii) SGI's licenses under Section 4
                 above shall be limited to Patents obtained or filed, and
                 improvements developed, by MIPS only and not the acquirer's
                 other business units. If MIPS is not maintained as a
                 independent business unit as set forth above then: (i) SGI's
                 licenses under Section 4 above shall apply to all Patents
                 obtained or filed, and improvements developed, by the acquirer
                 or any of its business units, and (ii) MIPS license will
                 terminate, provided that in the event there is a pre-existing
                 license agreement between SGI and the acquirer, the licenses
                 shall continue within the scope of such preexisting licenses
                 subject to the payment of any royalties due SGI under such pre-
                 existing agreement.

          8.2.2. SGI.  In the event more than fifty (50%) of the outstanding
                 ---                                                        
                 shares or securities (representing the right to vote for the
                 election of directors or other managing authority) of SGI
                 becomes owned or controlled directly or indirectly by a third
                 party the licenses granted to SGI pursuant to Section 2.2 above
                 shall be limited to use only within the SGI Field of Use.

     8.3. MIPS understands that SGI may divest some or all of its assets in the
          future; and MIPS agrees to grant such new entity a non-exclusive
          license similar in scope and on similar terms and conditions upon
          SGI's written request.

9.   INFRINGEMENT ACTIONS

     9.1. Infringement Actions within SGI's Field of Use.  For so long as the
          ----------------------------------------------                     
          licenses granted to SGI under the MIPS Patents under Section 2.2 above
          remain exclusive, MIPS agrees that SGI can bring suit, without MIPS's
          consent, against any third party infringing the MIPS Patents within
          the SGI Exclusive Field of Use.  MIPS agrees, at SGI's expense, to
          make available at reasonable times and under appropriate conditions
          all relevant personnel, records, papers, information, samples,
          specimens and other similar materials in its possession.  MIPS agrees
          to provide, at SGI's expense, all cooperation reasonably necessary or
          useful to allow SGI to litigate or settle such suit, including without
          limitation, becoming party to the suit.

     9.2. Request to Bring Suit.  In the event a Party reasonably believes that
          ---------------------                                                
          a third party infringes one or more of the patents licensed to it
          pursuant to this Agreement, it may request that the other party
          ("Patent Owner") bring an infringement action against such third party
          infringer.  Upon receiving such request, the Patent Owner shall use
          its reasonable efforts to file such claim unless the Patent Owner can
          demonstrate that it is not commercially reasonable for it to do so.
          The requesting party shall reimburse Patent Owner for all costs and
          expenses associated with filing, litigating and settling such claim.

           conditions of this Agreement shall be treated as confidential
           information and that neither party will disclose the terms or
           conditions to any third party without the prior written consent of
           the other party, provided, however, that each party may disclose the

terms of this Agreement shall be expended by the disclosing party in complying
with such an order, including obtaining a protective order to the extent
reasonably possible.  The parties shall cooperate in preparing and releasing an
announcement or other form of publicity, if any, relating to this Agreement.

     10.3. Export Controls.  Each party understands and acknowledges that
           ---------------

          permitted by this Agreement and to its agents or consultants under
          the terms and conditions of a signed, written confidential
          disclosure agreement with terms and conditions which prohibit
          disclosure to other parties, and which are otherwise at least as
          restrictive as the terms of subsections (i)-(iii) of this Section

          Filing, and the submission thereof to the appropriate governmental
          entity. If SGI has not yet received a proposed Filing from Company on
          an item of Foreground Technology, and SGI believes that a Filing
          should be made with respect thereto, SGI may submit a written request
          to Company that Company proceed with the preparation of such Filing,
          provided, however, that Company may, in its sole discretion, proceed
          or decline to proceed with the preparation of such Filing. If Company

          Filing shall submit such Filing to the other party for its review and
          approval prior to any submission to any governmental entity. A Filing
          shall be deemed accepted by the receiving party if the receiving party
          does not provide written notice of rejection to the submitting party
          within thirty (30) (or such shorter period as the parties may agree
          upon) days after the submitting party's notice thereof. If a party
          rejects a Filing, it shall include with its rejection notice a
          detailed description of its reason(s) for rejection, and shall make
          specific suggestions as to any modifications which it believes should
          be made to the form or content of such Filing prior to submission. If
          the submitting party believes that the modifications suggested by the
          receiving party are inappropriate, the submitting party's Coordinator
          shall contact the receiving party's Coordinator, and the Coordinators
          shall arrange and hold a meeting or discussion between appropriate
          representatives of the parties, at a mutually acceptable time and
          place, to determine a mutually acceptable form, content and time for
          the proposed Filing. Each party shall provide the other with copies of
          any correspondence, materials or communications submitted to or
          received from a governmental entity or a third party relating to any
          Filing. SGI will provide such information regarding the Background
          Technology, Foreground Technology and Developed Technology as Company
          may reasonably request for purposes of permitting Company and its
          advisors to evaluate actual or potential infringement claims directed
          at Company Products. Nothing in this Section 14.4 shall be interpreted
          to expand SGI's obligations under Section 9.5.

               14.5  ENFORCEMENT OF RIGHTS IN FOREGROUND TECHNOLOGY.   Before
          initiating any action against an alleged infringer of any rights in
          the Foreground Technology, each party (the "Enforcing Party") shall

          been granted a license to use the Foreground Technology by the other
          party or has not purchased from the other party products whose use
          would entitle the alleged infringer to use the Foreground Technology.
          If the alleged infringer has not obtained such a license or purchased
          such products, the Enforcing Party shall have the right, without
          further consent of the other party, to take such steps as it chooses,
          in its sole discretion, to enforce its rights XXXXXX and the other
          party shall provide such reasonable assistance as the Enforcing Party
          may request in connection therewith, provided either that such
          assistance does not require any out-of-pocket expenditures by the
          other party or that the Enforcing Party agrees to reimburse any such
          out-of-pocket expenses incurred by the other party. The Enforcing
          Party shall be entitled to retain all amounts recovered from the
          alleged infringer in connection with the litigation and/or settlement
          of any such action. The Enforcing Party shall defend, indemnify and
          hold harmless the other party and its Affiliates from and against any
          claim, suit or proceeding initiated against the other party by any
          alleged infringer in connection with or in response to actions
          initiated against the alleged infringer by the Enforcing Party,
          provided that (i) the other party gives the Enforcing Party notice of
          the claim, suit or proceeding promptly after commencement thereof,
          (ii) the other party gives the Enforcing Party sole authority to
          defend and/or resolve any such claim, suit or proceeding, and (iii)
          the other party gives the Enforcing Party all reasonable assistance
          requested by the Enforcing Party in connection with the defense and/or
          settlement of the claim, suit or proceeding, at the Enforcing Party's
          expense.

subject to the express provisions hereof:

          (i)    to select Participants from the Eligible Individuals;

          (ii)   to make Awards in accordance with the Plan;

          (iii)  to determine the number of shares of Common Stock subject to
     each Award or the cash amount payable in connection with an Award;

          (iv)   to determine the terms and conditions of each Award, including,
     without limitation, those related to vesting, forfeiture, payment and
     exercisability, and the effect, if any, of a Participant's termination of
     employment with the Company, and including the authority to amend the terms
     and conditions of an Award after the granting thereof to a Participant in a
     manner that is not, without the consent of the Participant, prejudicial to
     the rights of such Participant in such Award;

          (v)    to specify and approve the provisions of the Award Documents
     delivered to Participants in connection with their Awards;

          (vi)   to construe and interpret any Award Document delivered under
     the Plan;

          (vii)  to prescribe, amend and rescind rules and procedures relating
     to the Plan;

          (viii) to vary the terms of Awards to take account of tax,
     securities law and other regulatory requirements of foreign jurisdictions;

          (ix)   subject to the provisions of the Plan and subject to such
     additional limitations and restrictions as the Committee may impose, to
     delegate to one or more officers of the Company some or all of its
     authority under the Plan;

          (x)    to employ such legal counsel, independent auditors and
     consultants as it deems desirable for the administration of the Plan and to
     rely upon any opinion or computation received therefrom; and

     procedures as may be necessary or advisable for the administration of the
     Plan.
<PAGE>
 
                                       5

          (b) Plan Construction and Interpretation.  The Committee shall have
full power and authority, subject to the express provisions hereof, to construe
and interpret the Plan.

determinations by the Committee in carrying out and administering the Plan and
in construing and interpreting the Plan shall be final, binding and conclusive
for all purposes and upon all persons interested herein.

          (d) Delegation of Authority.  The Committee may, but need not, from
time to time delegate some or all of its authority under the Plan to an
Administrator consisting of one or more members of the Committee or of one or
more officers of the Company; provided, however, that the Committee may not
delegate its authority (i) to make Awards to Eligible Individuals who are
officers of the Company who are delegated authority by the Committee hereunder,
or (ii) under Sections 3(b) and 16 of the Plan.  Any delegation hereunder shall
be subject to the restrictions and limits that the Committee specifies at the
time of such delegation or thereafter.  Nothing in the Plan shall be construed
as obligating the Committee to delegate authority to an Administrator, and the
Committee may at any time rescind the authority delegated to an Administrator
appointed hereunder or appoint a new Administrator.  At all times, the
Administrator appointed under this Section 3(d) shall serve in such capacity at
the pleasure of the Committee.  Any action undertaken by the Administrator in
accordance with the Committee's delegation of authority shall have the same
force and effect as if undertaken directly by the Committee, and any reference
in the Plan to the Committee shall, to the extent consistent with the terms and
limitations of such delegation, be deemed to include a reference to the
Administrator.

          (e) Liability of Committee.  No member of the Committee shall be
liable for any action nor determination made in good faith, and the members of
the Committee shall be entitled to indemnification and reimbursement in the
manner provided in the Company's certificate of incorporation as it may be
amended from time to time.  In the performance of its responsibilities with
respect to the Plan, the Committee shall be entitled to rely upon information
and advice furnished by the Company's officers, the Company's accountants, the
Company's counsel and any other party the Committee deems necessary, and no
member of the Committee shall be liable for any action taken or not taken in
reliance upon any such advice.

          (f) Action by the Board.  Anything in the Plan to the contrary
notwithstanding, any authority or responsibility which, under the terms of the
Plan, may be exercised by the Committee may alternatively be exercised by the
Board.

 4.  EFFECTIVE DATE AND TERM

          The Plan shall become effective upon its adoption by the Board subject

meeting of stockholders to occur after the adoption of the Plan by the Board
(including any adjournment or adjournments thereof), the Plan and any Awards
made thereunder shall terminate ab initio and be of no further force and effect.
In no event shall any Awards be made under the Plan after the [fifth]

 5.  SHARES OF COMMON STOCK SUBJECT TO THE PLAN

5 Limit and again be available for Awards:

               (i)  The number of shares tendered to pay the exercise price of a
          Stock Option or other Award; and

               (ii) The number of shares withheld from any Award to satisfy a
          Participant's tax withholding obligations or, if applicable, to pay
          the exercise price of a Stock Option or other Award.

          In addition, any shares issued underlying Substitute Awards shall not
be counted against the Section 5 Limit and shall not be subject to Section 5(c)
below.

          (c) Special Limits.  Anything to the contrary in Section 5(a) above
notwithstanding, but subject to Section 15(b) below, the following special
limits shall apply to shares of Common Stock available for Awards under the

<PAGE>
 
                                       7

     [800,000] shares, of which no more than a number of shares equal to [10%]
     of the Section 5 Limit shall be in the form of Other Awards, provided,
     however, that any such Stock Awards, Restricted Stock or Other Awards that
     are issued in lieu of cash compensation that otherwise would be paid to a
     Participant, or in satisfaction of any other obligation owed by the Company
     to a Participant, shall not be counted against such limitation; and

          (ii)    The maximum number of shares of Common Stock that may be
     subject to Stock Options or Stock Appreciation Rights granted to any
     Eligible Individual in any fiscal year of the Company shall equal 198,000
     shares plus any shares which were available under this Section 5(c)(ii) for
     Awards of Stock Options or Stock Appreciation Rights to such Eligible
     Individual in any prior fiscal year but which were not covered by such
     Awards.

          (iii)   The maximum number of Performance Units  that may be granted
     to any Eligible Individual in any fiscal year of the Company shall equal
     198,000 units plus any Performance Units  which were available under this
     Section 5(c)(iii) for Awards of Performance Units to such Eligible
     Individual in any prior fiscal year but which were not covered by such
     Awards

6.   ELIGIBLE INDIVIDUALS

          Awards may be granted by the Committee to Eligible Individuals who are
officers or other key employees of the Company or Consultants; provided,
however, that Consultants shall not be eligible to receive Incentive Stock
Options.  Members of the Committee will not be eligible to receive Awards under
the Plan.  An individual's status as an Administrator will not, by itself,
affect his or her eligibility to participate in the Plan.

consist of Stock Options, Stock Appreciation Rights, Stock Awards, Restricted

under any other employee compensation plan of the Company, including the plan of
any acquired entity, or may be granted in satisfaction of the Company's
obligations under any such plan.

                                       8

          (b) Terms Set Forth in Award Document.  The terms and provisions of an
Award shall be set forth in a written Award Document approved by the Committee
and delivered or made available to the Participant as soon as administratively
practicable following the date of such Award.  The vesting, exercisability,
payment and other restrictions applicable to an Award (which may include,
without limitation, restrictions on transferability or provision for mandatory
resale to the Company) shall be determined by the Committee and set forth in the
applicable Award Document.   Notwithstanding the foregoing, the Committee may
accelerate (i) the vesting or payment of any Award, (ii) the lapse of
restrictions on any Award or (iii) the date on which any Stock Option, Stock
Appreciation Right or Other Award first becomes exercisable.

          (c) Termination of Employment and Change in Control.  The Committee
shall also have full authority to determine and specify in the applicable Award
Document the effect, if any, that a Participant's termination of employment for
any reason will have on the vesting, exercisability, payment or lapse of
restrictions applicable to an Award.  The date of a Participant's termination of
employment for any reason shall be determined in the sole discretion of the
Committee.  Similarly, the Committee shall have full authority to determine the
effect, if any, of a change in control of the Company on the vesting,
exercisability, payment or lapse of restrictions applicable to an Award, which
effect may be specified in the applicable Award Document or determined at a
subsequent time.

          (d) Dividends and Dividend Equivalents.  The Committee may provide
Participants with the right to receive dividends or payments equivalent to
dividends or interest with respect to an outstanding Awards, which payments can
either be paid currently or deemed to have been reinvested in shares of Common
Stock, and can be made in Common Stock, cash or a combination thereof, as the
Committee shall determine.

the Participant to whom the Stock Option was granted to purchase a specified
number of shares of Common Stock during a specified period at a price that is
determined in accordance with Section 8(b) below.  Stock Options may be either
Nonqualified Stock Options or Incentive Stock Options.  The Committee will fix
the vesting and exercisability conditions applicable to a Stock Option, provided
that no Stock Option shall vest sooner than ten months from the date of grant
(subject to early vesting, if so provided by the Committee, upon death,
disability, termination of employment or change in control of the Company)[, but
provided further that such minimum vesting period shall not apply to any
Restoration Option].

          (b) Exercise Price.  The exercise price per share of Common Stock
purchasable under a Stock Option shall be fixed by the Committee at the time of
grant or, alternatively, shall be determined by a method specified by the
Committee at the time of grant; provided, however, that the exercise price per
share shall be no less than 100% of the Fair Market Value per share on the date
of grant (or if the exercise price is not fixed on the date of grant, then on
such date as the exercise price is fixed); and provided further that, except as
provided in Section 15(b) below, the exercise price per share of Common Stock
applicable to a Stock Option may not be adjusted or amended, including by means
of amendment, cancellation or the replacement of such Stock Option with a
subsequently awarded Stock Option. Notwithstanding the foregoing, the exercise
price per share of a Stock Option that is a Substitute Award may be less than
the Fair Market Value per share on the date of award, provided that the excess
of:

          (i)   the aggregate Fair Market Value (as of the date such Substitute
          Award is granted) of the shares of Common Stock subject to the
          Substitute Award, over

          (ii)  the aggregate exercise price thereof,
     does not exceed the excess of:

          (iii) the aggregate fair market value (as of the time immediately
          preceding the transaction giving rise to the Substitute Award, such
          fair market value to be determined by the Committee) of the shares of
          the predecessor entity that were subject to the award assumed or
          substituted for by the Company, over

          (iv)  the aggregate exercise price of such shares.

          (c)   Option Term. The term of each Stock Option shall be fixed by the
Committee and shall not exceed ten years from the date of grant.

          (d)   Incentive Stock Options.  Each Stock Option granted pursuant to
the Plan shall be designated at the time of grant as either an Incentive Stock
Option or as a Nonqualified Stock Option.  No Incentive Stock Option may be
issued pursuant to the Plan to any individual who, at the time the Stock Option
is granted, owns stock possessing more than 10% of the total combined voting
power of all classes of stock of the Company or any of its Subsidiaries, unless
(A) the exercise price determined as of the date of grant is at least 110% of
the Fair Market Value on the date of grant of the shares of Common Stock subject
to such Stock Option, and (B) the Incentive Stock Option is not exercisable more
than five years from the date of grant thereof.  No Incentive Stock Option may
be granted under the Plan after the tenth anniversary of the Effective Date.

                                      10

          (e) Method of Exercise.  Subject to the provisions of the applicable
Award Document, the exercise price of a Stock Option may be paid in cash or
previously owned shares or a combination thereof and, if the applicable Award
Document so provides, in whole or in part through the withholding of shares
subject to the Stock Option with a value equal to the exercise price.  In
accordance with the rules and procedures established by the Committee for this
purpose, the Stock Option may also be exercised through a "cashless exercise"
procedure approved by the Committee involving a broker or dealer approved by the
Committee, that affords Participants the opportunity to sell immediately some or
all of the shares underlying the exercised portion of the Stock Option in order
to generate sufficient cash to pay the Stock Option exercise price and/or to
satisfy withholding tax obligations related to the Stock Option.


9.   STOCK APPRECIATION RIGHTS

          (a) General.  A Stock Appreciation Right shall entitle a Participant
to receive, upon satisfaction of the conditions to the payment specified in the
applicable Award Document, an amount equal to the excess, if any, of the Fair
Market Value on the exercise date of the number of shares of Common Stock for
which the Stock Appreciation Right is exercised, over the exercise price for
such Stock Appreciation Right specified in the applicable Award Document.  The
exercise price per share of Common Stock covered by a Stock Appreciation Right
shall be fixed by the Committee at the time of grant or, alternatively, shall be
determined by a method specified by the Committee at the time of grant;
provided, however, that, except as provided in Section 9(b) below, the exercise
price per share shall be no less than 100% of the Fair Market Value per share on
the date of grant (or if the exercise price is not fixed on the date of grant,
then on such date as the exercise price is fixed); and provided further, that,
except as provided in Section 15(b) below, the exercise price per share of
Common Stock subject to a Stock Appreciation Right may not be adjusted or
amended, including by means of amendment, cancellation or the replacement of
such Stock Appreciation Right with a subsequently awarded Stock Appreciation
Right.  Notwithstanding the foregoing, the exercise price per share of a Stock
Appreciation Right that is a Substitute Award may be less than the Fair Market
Value per share on the date of award, provided, that such exercise price is not
less than the minimum exercise price that would be permitted for an equivalent
Stock Option as determined in accordance with Section 8(b) above.  At the sole
discretion of the Committee, payments to a Participant upon exercise of a Stock
Appreciation Right may be made in cash, in shares of Common Stock having an
aggregate Fair Market Value as of the date of exercise equal to such amount, or
in a combination of cash and shares of Common Stock having an aggregate value as
of the date of exercise equal to such amount.  A Stock Appreciation Right may be
granted alone or in addition to other Awards, or in tandem with a Stock Option.
<PAGE>
 
                                      11

          (b) Stock Appreciation Rights in Tandem with Stock Options.  A Stock
Appreciation Right granted in tandem with a Stock Option may be granted either
at the same time as such Stock Option or subsequent thereto.  If granted in
tandem with a Stock Option, a Stock Appreciation Right shall cover the same
number of shares of Common Stock as covered by the Stock Option (or such lesser
number of shares as the Committee may determine) and shall be exercisable only
at such time or times and to the extent the related Stock Option shall be
exercisable, and shall have the same term and exercise price as the related
Stock Option (which, in the case of a Stock Appreciation Right granted after the
grant of the related Stock Option, may be less than the Fair Market Value per
share on the date of grant of the tandem Stock Appreciation Right).  Upon
exercise of a Stock Appreciation Right granted in tandem with a Stock Option,
the related Stock Option shall be canceled automatically to the extent of the
number of shares covered by such exercise; conversely, if the related Stock
Option is exercised as to some or all of the shares covered by the tandem grant,
the tandem Stock Appreciation Right shall be canceled automatically to the
extent of the number of shares covered by the Stock Option exercise.


10. STOCK AWARDS

          (a) General.  A Stock Award shall consist of one or more shares of
Common Stock granted to a Participant for no consideration other than the
provision of services (or, if required by applicable law in the reasonable
judgment of the Company, for payment of the par value of such shares).  Stock
Awards shall be subject to such restrictions (if any) on transfer or other
incidents of ownership for such periods of time, and shall be subject to such
conditions of vesting, as the Committee may determine and as shall be set forth
in the applicable Award Document.

          (b) Distributions.  Any shares of Common Stock or other securities of
the Company received by a Participant to whom a Stock Award has been granted as
a result of a stock distribution to holders of Common Stock or as a stock
dividend on Common Stock shall be subject to the same terms, conditions and
restrictions as such Stock Award.


11.  RESTRICTED STOCK

          (a) General   An Award of Restricted Stock shall consist of a grant of
one or more shares of Common Stock to a Participant for no consideration other
than the provision of services or may be offered for sale to a Participant at a
purchase price determined by the Committee, subject to the terms and conditions
established by the Committee in connection with the Award and as set forth in
the applicable Award Document.  Such shares of Common Stock shall be subject to
such restrictions on transfer or other incidents of ownership for such 
<PAGE>
 
                                      12


periods of time, and shall be subject to such conditions of vesting, as the
Committee may determine and as shall be set forth in the Award Document relating
to such stock. If shares of Common Stock are offered for sale under the Plan,
the purchase price shall be payable in cash, or, in the sole discretion of the
Committee and to the extent provided in any applicable Award Document, in shares
of Common Stock already owned by the Participant, for other consideration
acceptable to the Committee or in any combination of cash, shares of Common
Stock or such other consideration. Restricted Stock that is granted in respect
of individual or corporate performance shall vest no sooner than [one year] from
the date of grant, and Restricted Stock that is granted in connection with
hiring or retention arrangements between the Company and a Participant shall
vest no sooner than [three years] from the date of grant (subject, in either
such case, to early vesting, if so provided by the Committee, upon death,
disability, termination of employment or a change in control of the Company).

          (b) Share Certificates; Rights and Privileges.  At the time Restricted
Stock is granted or sold to a Participant, share certificates representing the
appropriate number of shares or Restricted Stock shall be registered in the name
of the Participant but shall be held by the Company in custody for the account
of such person.  The certificates shall bear a legend restricting their
transferability as provided herein.  Except for such restrictions on transfer or
other incidents of ownership as may be determined by the Committee and set forth
in the Award Document relating to an award or sale of Restricted Stock, a
Participant shall have the rights of a stockholder as to such Restricted Stock,
including the right to receive dividends and the right to vote in accordance
with the Company's certificate of incorporation.

          (c) Distributions.  Any shares of Common Stock or other securities of
the Company received by a Participant to whom Restricted Stock has been granted
or sold as a result of a stock distribution to holders of Common Stock or as a
stock dividend on Common Stock shall be subject to the same terms, conditions
and restrictions as such Restricted Stock.


12. PERFORMANCE UNITS

          Performance Units may be granted as fixed or variable share- or
dollar-denominated units subject to such conditions of vesting and time of
payment as the Committee may determine and as shall be set forth in the
applicable Award Document relating to such Performance Units.  Performance Units
may be paid in Common Stock upon the satisfaction of the applicable performance
criteria as described in the Award Document, cash or a combination of Common
Stock and cash, as the Committee may determine.
<PAGE>
 
                                      13

13. OTHER AWARDS

          The Committee shall have the authority to specify the terms and
provisions of other forms of equity-based or equity-related Awards not described
above which the Committee determines to be consistent with the purpose of the
Plan and the interests of the Company, which Awards may provide for cash
payments based in whole or in part on the value or future value of Common Stock,
for the acquisition or future acquisition of Common Stock, or any combination
thereof.  Other Awards shall also include cash payments (including the cash
payment of dividend equivalents) under the Plan which may be based on one or
more criteria determined by the Committee which are unrelated to the value of
Common Stock and which may be granted in tandem with, or independent of, other
Awards under the Plan.


14. CERTAIN RESTRICTIONS

          (a) Transfers.  Unless the Committee determines otherwise, no Award
shall be transferable other than by will or by the laws of descent and
distribution or pursuant to a domestic relations order; provided, however, that
the Committee may, in its discretion and subject to such terms and conditions as
it shall specify, permit the transfer of an Award for no consideration to a
Participant's family members or to one or more trusts or partnerships
established in whole or in part for the benefit of one or more of such family
members (collectively, "Permitted Transferees").  Any Award transferred to a
Permitted Transferee shall be further transferable only by will or the laws of
descent and distribution or, for no consideration, to another Permitted
Transferee of the Participant.  The Committee may in its discretion permit
transfers of Awards other than those contemplated by this Section 14.

          (b) Exercise.  During the lifetime of the Participant, a Stock Option,
Stock Appreciation Right or similar-type Other Award shall be exercisable only
by the Participant or by a Permitted Transferee to whom such Stock Option, Stock
Appreciation Right or Other Award has been transferred in accordance with
Section 14(a).


15. RECAPITALIZATION OR REORGANIZATION

          (a) Authority of the Company and Stockholders.  The existence of the
Plan, the Award Documents and the Awards granted hereunder shall not affect or
restrict in any way the right or power of the Company or the stockholders of the
Company to make or authorize any adjustment, recapitalization, reorganization or
other change in the Company's capital structure or its business, any merger or
consolidation of the Company, any issue of stock or of options, warrants or
rights to purchase stock or of bonds, debentures, preferred or prior 
<PAGE>
 
                                      14

preference stocks whose rights are superior to or affect the Common Stock or the
rights thereof or which are convertible into or exchangeable for Common Stock,
or the dissolution or liquidation of the Company, or any sale or transfer of all
or any part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise.

          (b) Change in Capitalization.  Notwithstanding any provision of the
Plan or any Award Document, the number and kind of shares authorized for
issuance under Section 5(a) above, including the maximum number of shares
available under the special limits provided for in Section 5(c) above, may be
equitably adjusted in the sole discretion of the Committee in the event of a
stock split, stock dividend, recapitalization, reorganization, merger,
consolidation, extraordinary dividend, split-up, spin-off, combination, exchange
of shares, warrants or rights offering to purchase Common Stock at a price
substantially below Fair Market Value or other similar corporate event affecting
the Common Stock in order to preserve, but not increase, the benefits or
potential benefits intended to be made available under the Plan.  In addition,
upon the occurrence of any of the foregoing events, the number of outstanding
Awards and the number and kind of shares subject to any outstanding Award and
the purchase price per share, if any, under any outstanding Award may be
equitably adjusted (including by payment of cash to a Participant) in the sole
discretion of the Committee in order to preserve the benefits or potential
benefits intended to be made available to Participants granted Awards.  Such
adjustments shall be made by the Committee, whose determination as to what
adjustments shall be made, and the extent thereof, shall be final.  Unless
otherwise determined by the Committee, such adjusted Awards shall be subject to
the same vesting schedule and restrictions to which the underlying Award is
subject.


16. AMENDMENTS; TERMINATION

          The Board or Committee may at any time and from time to time alter,
amend, suspend or terminate the Plan in whole or in part; provided, however,
that any amendment which under the requirements of any applicable law or stock
exchange rule must be approved by the stockholders of the Company shall not be
effective unless and until such stockholder approval has been obtained in
compliance with such law or rule; and provided further that, except as
contemplated by Section 15(b) above, the Board or Committee may not, without the
approval of the Company's stockholders, increase the maximum number of shares
issuable under the Plan or reduce the exercise price of a Stock Option or Stock
Appreciation Right.  No termination or amendment of the Plan may, without the
consent of the Participant to whom an Award has been granted, adversely affect
the rights of such Participant under such Award. Notwithstanding any provision
herein to the contrary, the Board or Committee shall have broad authority to
amend the Plan or any Award under the Plan to take into account changes in
applicable tax laws, securities laws, accounting rules and other applicable
state and federal laws.

                                      15

17. MISCELLANEOUS

          (a) Tax Withholding.   The Company may require any individual entitled
to receive a payment in respect of an Award to remit to the Company, prior to
such payment, an amount sufficient to satisfy any Federal, state or local tax
withholding requirements.  The Company shall also have the right to deduct from
all cash payments made pursuant to or in connection with any Award any Federal,
state or local taxes required to be withheld with respect to such payments.  In
addition, the Company may permit any individual to whom an Award has been made
to satisfy, in whole or in part, such obligation to remit taxes, by directing
the Company to withhold shares of Common Stock that would otherwise be received
by such individual upon settlement or exercise of such Award or by delivering to
the Company shares of Common Stock owned by the individual prior to exercising
the option, subject to such rules as the Committee may establish from time to
time.  The value of any share of Common Stock to be withheld by the Company
pursuant to this Section 17(a) shall be the Fair Market Value on the date to be
used to determine the amount of tax to be withheld.

          (b) No Right to Grants or Employment.  No Eligible Individual or
Participant shall have any claim or right to receive grants of Awards under the
Plan.  Nothing in the Plan or in any Award or Award Document shall confer upon
any employee of the Company any right to continued employment with the Company
or interfere in any way with the right of the Company to terminate the
employment of any of its employees at any time, with or without cause.

          (c) Other Compensation.  Nothing in this Plan shall preclude or limit
the ability of the Company to pay any compensation to a Participant under the
Company's other compensation and benefit plans and programs.

          (d) Other Employee Benefit Plans.  Payments received by a Participant
under any Award made pursuant to the Plan shall not be included in, nor have any
effect on, the determination of benefits under any other employee benefit plan
or similar arrangement provided by the Company, unless otherwise specifically
provided for under the terms of such plan or arrangement or by the Committee.

          (e) Unfunded Plan.  The Plan is intended to constitute an unfunded
plan for incentive compensation.  Prior to the payment or settlement of any
Award, nothing contained herein shall give any Participant any rights that are
greater than those of a general creditor of the Company.  In its sole
discretion, the Committee may authorize the creation of trusts or other
arrangements to meet the obligations created under the Plan to deliver Common
Stock or payments in lieu thereof with respect to awards hereunder.
<PAGE>
 
                                      16

          (f) Securities Law Restrictions.  The Committee may require each
Eligible Individual purchasing or acquiring shares of Common Stock pursuant to a
Stock Option or other Award under the Plan to represent to and agree with the
Company in writing that such Eligible Individual is acquiring the shares for
investment and not with a view to the distribution thereof.  All certificates
for shares of Common Stock delivered under the Plan shall be subject to such
stock-transfer orders and other restrictions as the Committee may deem advisable
under the rules, regulations, and other requirements of the Securities and
Exchange Commission, any exchange upon which the Common Stock is then listed,
and any applicable federal or state securities law, and the Committee may cause
a legend or legends to be put on any such certificates to make appropriate
reference to such restrictions.  No shares of Common Stock shall be issued
hereunder unless the Company shall have determined that such issuance is in
compliance with, or pursuant to an exemption from, all applicable federal and
state securities laws.

          (g) Compliance with Rule 16b-3.  Notwithstanding anything contained in
the Plan or in any Award Document to the contrary, if the consummation of any
transaction under the Plan would result in the possible imposition of liability
on a Participant pursuant to Section 16(b) of the Exchange Act, the Committee
shall have the right, in its sole discretion, but shall not be obligated, to
defer such transaction or the effectiveness of such action to the extent
necessary to avoid such liability, but in no event for a period longer than six
months.

          (h) Award Document.  In the event of any conflict or inconsistency
between the Plan and any Award Document, the Plan shall govern, and the Award
Document shall be interpreted to minimize or eliminate any such conflict or
inconsistency.

          (i) Expenses.  The costs and expenses of administering the Plan shall
be borne by the Company.

          (j) Application of Funds.  The proceeds received from the Company from
the sale of Common Stock or other securities pursuant to Awards will be used for
general corporate purposes.

          (k) Applicable Law.  Except as to matters of federal law, the Plan and
all actions taken thereunder shall be governed by and construed in accordance
with the laws of the State of Delaware without giving effect to conflicts of law
principles.

he or she would otherwise have received during said Offering Period.

          (b) All payroll deductions authorized by a participant shall be

deductions during an Offering Period by completing and filing with the Company a
new authorization for payroll deduction, provided that the Board may, in its
discretion, impose reasonable and uniform restrictions on participants' ability
to change the rate of payroll deductions.  The change in rate shall be effective
no later than fifteen (15) days following the Company's receipt of the new
authorization.  A participant may decrease or increase the amount of his or her
payroll deductions as of the beginning of an Offering Period by completing and
filing with the Company, at least fifteen (15) days prior to the beginning of
such Offering Period, a new payroll deduction authorization.

          (d) Notwithstanding the foregoing, to the extent necessary, but only
to such extent, to comply with Section 423(b)(8) of the Code and paragraph 3(b)
herein, a participant's payroll deductions may be automatically decreased to 0%
at such time during any Exercise Period which is scheduled to end in the current
calendar year that the aggregate of all payroll deductions accumulated with
respect to the applicable Offering Period and any other Offering Period ending
within the same calendar year equals $25,000.  Payroll deductions shall
recommence at the rate provided in such participant's subscription agreement at
the beginning of the next succeeding Exercise Period, unless terminated by the
participant as provided in paragraph 10.

     7.   GRANT OF OPTION.

          (a) On each Offering Date, each participant shall be granted an option
to purchase on each Exercise Date (at the per share option price) a number of
full shares of Common Stock arrived at by dividing such participant's total
payroll deductions to be accumulated prior to such Exercise Date and retained in
the participant's account as of the Exercise Date by the lower of (i) eighty-
five percent (85%) of the fair market value of a share of Common Stock at the
Offering Date, or (ii) eighty-five percent (85%) of the fair market value of a
share of Common Stock at the Exercise Date; provided, however, that the maximum
number of shares a participant may purchase during each Offering Period shall be
determined by (i) dividing 
<PAGE>
 
                                       5

$50,000 by the fair market value of a share of Common Stock on the Offering Date
or (ii) if less, by the "Maximum Cap" set for such Offering Period; and provided
further that such purchase shall be subject to the limitations set forth in
paragraphs 3(b) and 12 hereof. The "Maximum Cap" for each Offering Period shall
be the number of shares purchasable under the Plan during that Offering Period
with the maximum payroll deductions permitted by paragraph 6(a) hereof, based
upon the fair market value of a share of Common Stock at the beginning of the
Offering Period. The fair market value of a share of Common Stock shall be
determined as provided in paragraph 7(b) herein.

          (b) The option price per share of such shares shall be the lower of:
(i) eighty-five percent (85%) of the fair market value of a share of Common
Stock at the Offering Date; or (ii) eighty-five percent (85%) of the fair market
value of a share of Common Stock at the Exercise Date.  The fair market value of
a share of Common Stock on said dates shall be determined by the Board, based
upon such factors as the Board determines relevant; provided, however, that if
there is a public market for the Common Stock, the fair market value of a share
of Common Stock on a given date shall be the reported bid price for the Common
Stock as of such date; or, in the event that the Common Stock is listed on a
national securities exchange, the fair market value of a share of Common Stock
shall be an amount equal to the average of the high and low sales price of a
share of Common Stock on the exchange as of such date.

     8.   EXERCISE OF OPTION.

          (a) Unless a participant withdraws from the Offering Period as
provided in paragraph 10, his or her option for the purchase of shares will be
exercised automatically at each Exercise Date, and the maximum number of full
shares subject to option will be purchased at the applicable option price with
the accumulated payroll deductions in his or her account.  The shares purchased
upon exercise of an option hereunder shall be deemed to be transferred to the
participant on the Exercise Date.

          (b) During his or her lifetime, a participant's option to purchase
shares hereunder is exercisable only by the participant.

          (c) The Board may require, as a condition precedent to any purchase
under the Plan, appropriate arrangements with the participant for the
withholding of any applicable Federal, state, local or foreign withholding or
other taxes.

     9.   DELIVERY.  As promptly as practicable after the Exercise Date of each
Offering Period, the Company shall arrange for the shares purchased upon
exercise of his or her option to be electronically credited to the participant's
designated brokerage account at one of the securities brokerage firms
participating in the Company's direct deposit program from time to time.  Any
cash remaining to the credit of a participant's account under the Plan after a
purchase by him or her of shares at the Exercise Date of each Offering Period
which merely represents a fractional 
<PAGE>
 
                                       6

share shall be credited to the participant's account for the next subsequent
Offering Period; any additional cash shall be returned to said participant.

                                       7

     10.  WITHDRAWAL; TERMINATION OF EMPLOYMENT.

          (a) A participant may withdraw all, but not less than all, the payroll
deductions credited to his or her account under the Plan at any time prior to an
Exercise Date by giving written notice to the Company on a form provided for
such purpose.  If the participant withdraws from the Offering Period, all of the
participant's payroll deductions credited to his or her account will be paid to
the participant as soon as practicable after receipt of the notice of withdrawal
and his or her option for the current Offering Period will be automatically
canceled, and no further payroll deductions for the purchase of shares will be
made during such Offering Period or subsequent Offering Periods, except pursuant
to a new subscription agreement filed in accordance with paragraph 6 hereof.

          (b) Upon termination of the participant's Continuous Status as an
Employee prior to an Exercise Date of an Offering Period for any reason,
including retirement or death, the payroll deductions accumulated in his or her
account will be returned to him or her as soon as practicable after such
termination or, in the case of death, to the person or persons entitled thereto
under paragraph 14, and his or her option will be automatically canceled.

          (c) In the event an Employee fails to remain in Continuous Status as
an Employee of the Company for at least twenty (20) hours per week during an
Offering Period in which the employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan, and the payroll deductions credited
to his or her account will be returned to the participant and the option
canceled.

          (d) A participant's withdrawal from an Offering Period will not have
any effect upon his or her eligibility to participate in a succeeding Offering
Period by executing and delivering to the Company a new payroll deduction form
or in any similar plan which may hereafter be adopted by the Company.

     11.  AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD.  In the event that
the fair market value of the Common Stock is lower on the first day of an
Exercise Period (the "Subsequent Exercise Period") than it was on the first
Offering Date for that Offering Period (the "Initial Offering Period"), all
participants in the Plan on the first day of the Subsequent Exercise Period
shall be deemed to have withdrawn from the Initial Offering Period on the first
day of the Subsequent Exercise Period and to have enrolled as participants in a
new Offering Period which begins on or about that day.  A participant may elect
to remain in the Initial Offering Period by filing a written statement declaring
such election with the Company prior to the time of the automatic change to the
new Offering Period.

     12.  INTEREST.  No interest shall accrue on the payroll deductions of a
participant in the Plan.

                                       8
<PAGE>
 
                                       9

     13.  STOCK.

          (a) The maximum number of shares of the Common Stock which shall be
reserved for sale under the Plan shall be 600,000 shares, subject to adjustment
upon changes in capitalization of the Company as provided in paragraph 19.  The
shares to be sold to participants in the Plan may be, at the election of the
Company, either treasury shares or shares authorized but unissued.  If the total
number of shares which would otherwise be subject to options granted pursuant to
paragraph 7(a) hereof on the Offering Date of an Offering Period exceeds the
number of shares then available under the Plan (after deduction of all shares
for which options have been exercised or are then outstanding), the Company
shall make a pro rata allocation of the shares remaining available for option
grant in as uniform and equitable a manner as is practicable.  In such event,
the Company shall give written notice of such reduction of the number of shares
subject to the option to each participant affected thereby and shall return any
excess funds accumulated in each participant's account as soon as practicable
after the affected Exercise Date of such Offering Period.

          (b) A participant will have no interest or voting rights in shares
covered by his or her option until such option has been exercised.

          (c) Shares to be delivered to a participant under the Plan will be
credited electronically to a brokerage account in the name of the participant at
one of the brokerage firms participating from time to time in the Company's
direct deposit program.

     14.  ADMINISTRATION.  The Plan shall be administered by the Board or the
Committee.  The Board or the Committee shall have the authority to (i) make all
factual determinations in the administration or interpretation of the Plan, (ii)
establish administrative regulations to further the purpose of the Plan, and
(iii) take any other action desirable or necessary to interpret, construe or
implement properly the provisions of the Plan.  The administration,
interpretation or application of the Plan by the Board or the Committee shall be
final, conclusive and binding upon all participants.  Members of the Board or
the Committee who are eligible Employees are permitted to participate in the
Plan, provided that:

          (a) Members of the Board who participate in the Plan may not vote on
any matter affecting the administration of the Plan or the grant of any option
pursuant to the Plan.

          (b) If a Committee is established to administer the Plan, no member of
the Board who participates in the Plan may be a member of the Committee.

                                      10

     15.  DESIGNATION OF BENEFICIARY.

          (a) A participant may file a written designation of a beneficiary who
is to receive shares and/or cash, if any, from the participant's account under
the Plan in the event of such participant's death at a time when cash or shares
are held for his or her account.

          (b) Such designation of beneficiary may be changed by the participant
at any time by written notice.  In the event of the death of a participant in
the absence of a valid designation of a beneficiary who is living at the time of
such participant's death, the Company shall deliver such shares and/or cash to
the executor or administrator of the estate of the participant; or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such shares and/or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may reasonably designate.

     16.  RIGHTS NOT TRANSFERABLE.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in paragraph 15 hereof) by the participant.  Any
such attempt at assignment, transfer, pledge or other disposition shall be
without effect, except that the Company may treat such act as an election to
withdraw funds in accordance with paragraph 10.

     17.  USE OF FUNDS.  All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     18.  REPORTS.  Individual accounts will be maintained for each participant
in the Plan. Statements of account will be given to participating Employees as
soon as practicable following each Exercise Date.  Such statements will set
forth the amounts of payroll deductions, the per share purchase price, the
number of shares purchased and the remaining cash balance, if any.

     19.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  Subject to any required
action by the stockholders of the Company, the number of shares of Common Stock
covered by each option under the Plan which has not yet been exercised and the
number of shares of Common Stock which have been authorized for issuance under
the Plan but have not yet been placed under option (collectively, the
"Reserves"), as well as the price per share of Common Stock covered by each
option under the Plan which has not yet been exercised, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
<PAGE>
 
                                      11

Stock resulting from a stock split, stock dividend, combination or
reclassification of the Common Stock or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issue by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to option.

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Board.  In the event of a
proposed sale of all or substantially all of the assets of the Company, or the
merger of the Company with or into another corporation, each option under the
Plan shall be assumed or an equivalent option shall be substituted by such
successor corporation or a parent or subsidiary of such successor corporation,
unless the Board determines, in the exercise of its sole discretion and in lieu
of such assumption or substitution, that the participant shall have the right to
exercise the option as to all of the optioned stock, including shares as to
which the option would not otherwise be exercisable.  If the Board makes an
option fully exercisable in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify the participant that the option
shall be fully exercisable, and the option will terminate upon the expiration of
such period.

     The Board may, if it so determines in the exercise of its sole discretion,
also make provision for adjusting the Reserves, as well as the price per share
of Common Stock covered by each outstanding option, in the event that the
Company effects one or more reorganizations, recapitalizations, rights offerings
or other increases or reductions of shares of its outstanding Common Stock, and
in the event of the Company being consolidated with or merged into any other
corporation.

     20.  AMENDMENT OR TERMINATION.  The Board may at any time and for any
reason terminate or amend the Plan.  Except as provided in paragraph 19, no such
termination will affect options previously granted.  Except as provided in
paragraph 19, no amendment may make any change in any option theretofore granted
which adversely affects the rights of any participant. In addition, to the
extent necessary, but only to such extent, to comply with Rule 16b-3 under the
Securities Exchange Act of 1934, as amended, or with Section 423 of the Code (or
any successor rule or provision or any other applicable law or regulation), the
Company shall obtain stockholder approval of an amendment in such a manner and
to such a degree as so required.

     21.  NOTICES.  All notices or other communications by a participant to the
Company in connection with the Plan shall be deemed to have been duly given when
received in the form 
<PAGE>
 
                                      12


specified by the Company at the location, or by the person, designated by the
Company for the receipt thereof. Notices given by means of the Company's [OnLine
HR system] will be deemed to be written notices under the Plan.

     22.  STOCKHOLDER APPROVAL.  The Plan was adopted by the Board on
[__________, 1998] and approved by the shareholders of the Company on [________,
1998] in accordance with the requirements of Section 423(b)(2) of the Code.

     23.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

     As a condition to the exercise of an option, if required by applicable
securities laws, the Company may require the participant for whose account the
option is being exercised to represent and warrant at the time of such exercise
that the shares are being purchased only for investment and without any present
intention to sell or distribute such shares if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
applicable provisions of law.

     24.  NO RIGHT TO EMPLOYMENT.  Nothing shall confer upon any employee of the
Company any right to continued employment with the Company any right to
continued employment with the Company or interfere in any way with the right of
the Company to terminate the employment of any of its employees at any time,
with or without cause.

     25.  TERM OF PLAN.  The Plan shall remain in effect until [__________ ,
2008], unless terminated earlier in accordance with Paragraph 20.

     26.  GOVERNING LAW.  All rights and obligations under the Plan shall be
construed and interpreted in accordance with the laws of the State of Delaware,
without giving effect to principles of conflicts of laws.

[LETTERHEAD OF SILICON GRAPHICS]


                                 March 1, 1998


Mr. Lavi Lev
21771 Heber Way
Saratoga CA 95070


          Re:  Forgiveness of Loan


Dear Lavi;

          This letter agreement is entered into as of March 1, 1998 ("Effective
Date") by and between Lavi A. Lev ("Employee") and Sarah Lev (collectively,
"Borrower") and Silicon Graphics, Inc. ("SGI") with regard to the forgiveness of
Borrower's obligations under that certain Promissory Note (Forgivable Loan)
dated January 9, 1997 ("Note") in the original principal sum of $400,000. As of
the Effective Date, the outstanding balance of principal under the Note is
$282,334.

          Effective as of the Effective Date, SGI hereby forgives Borrower's
obligation to pay to SGI the principal sum of $282,334 under the Note. Such
forgiveness will be treated as compensation to Employee, and Borrower shall be
responsible for any individual tax liability associated with the forgiveness of
principal and any imputed interest; provided, however, that following SGI's
receipt of an original of this letter agreement signed by Borrower, SGI agrees
to pay to Employee the sum of One Hundred Fifty Thousand Dollars ($150,000) to
assist Borrower in paying such income tax liability. The foregoing payment by
SGI will be treated as compensation to Employee and subject to applicable tax
withholdings and payroll taxes. Borrower shall be responsible for any individual
tax liability resulting from such payment.  As of the Effective Date, any
monthly housing allowance provided to Employee shall terminate.

          If, on or before December 31, 2000, Employee shall terminate his
employment with SGI for any reason, SGI shall terminate Employee's employment
with SGI for cause, or Borrower shall be in default hereunder, then Borrower
shall immediately pay to SGI, in lawful money of the United States of America,
without abatement, demand, deduction, setoff or counterclaim, an amount equal to
(a) Eight Thousand Three Hundred Thirty-three and 33/100 Dollars ($8,333.33)
multiplied by (b) the number of calendar months from the date of such
termination of employment or default, as applicable, through December 31, 2000.
Payment for 

                                       1
<PAGE>
 
any partial month shall be prorated based upon a monthly payment of
Eight Thousand Three Hundred Thirty-three and 33/100 Dollars ($8,333.33) and a
thirty (30) day calendar month, and such prorated amount shall be added to the
amount calculated in the immediately preceding sentence.

          Borrower's obligations under this letter agreement are secured by that
certain Pledge Agreement of even date herewith ("Pledge Agreement") encumbering
certain stock options to acquire SGI common stock and such other collateral
described therein.

          SGI and Borrower acknowledge and agree that SGI intends to assign this
letter agreement to MIPS Technologies, Inc. ("MIPS") in connection with an
initial public offering of MIPS common stock, in which event all references
herein to SGI shall automatically be amended and modified to mean and refer to
MIPS, all obligations of SGI in connection with this letter agreement shall
automatically be assumed by MIPS, and SGI shall automatically be released from
any and all liability to Borrower in connection with this letter agreement.
Borrower shall execute such documents and instruments as may be requested by SGI
to evidence the foregoing within five (5) days following SGI's request therefor.

          Borrower shall be in default under this letter agreement if Borrower
fails to timely pay any amount or perform any other obligation of Borrower under
this letter agreement, the Pledge Agreement of even date herewith, the
Promissory Note (Forgivable Loan) of even date herewith in the original
principal amount of $250,000, the Promissory Note (Balloon Loan) of even date
herewith in the original principal amount of $250,000, the Deed of Trust with
Assignment of Rents dated January 6, 1997, as amended, or any other agreement or
instrument now or hereafter executed by Borrower to evidence or secure the
performance of Borrower's obligations thereunder. In addition, Borrower shall be
in default under this letter agreement upon any breach by Employee under any
severance agreement or proprietary information/invention agreement with SGI
and/or MIPS, as applicable. The reference to SGI in the immediately preceding
sentence shall not be amended as a result of an assignment of this letter
agreement to MIPS. Upon any default by Borrower under this letter agreement, any
amount payable by Borrower hereunder shall thereafter bear simple interest at
the lesser of ten percent (10%) per annum or the maximum rate permitted by law.
SGI's failure to exercise any rights or remedies hereunder shall not constitute
a waiver of SGI's right to exercise the same with respect to any prior or
subsequent defaults.

          If any provision of this letter agreement shall be invalid or
unenforceable for any reason, the same shall be ineffective, but the remainder
of this letter agreement shall not be affected thereby and shall remain in full
force and effect. This letter agreement supersedes any other agreements or
understandings between Borrower and SGI with regard to the forgiveness of the
Note. Time is of the essence of each and every obligation of Borrower hereunder.
Presentment and demand for payment, notice of dishonor, protest and notice of
protest are hereby waived by Borrower. None of the terms or provisions of this
letter agreement may be waived, altered, modified or amended except by a writing
signed by SGI and Borrower. The provisions of this letter agreement shall be
governed by California law. The covenants, terms and conditions

                                       2
<PAGE>
 
hereof shall bind the heirs, successors and assigns of Borrower and shall insure
to the benefit of the successors and assigns of SGI.

          The agreements and obligations of SGI under this letter agreement are
expressly conditioned upon SGI's receipt of an original of this letter agreement
executed by Borrower. Accordingly, please sign this letter agreement in the
spaces provided below and return the same to me.


                                    Sincerely,



                                    Kirk Froggatt,
                                    Vice President,
                                    Human Resources

AGREED AND ACCEPTED:

                                PROMISSORY NOTE
                          SECURED BY PLEDGE AGREEMENT
                               (FORGIVABLE LOAN)



         NOTICE:  THIS PROMISSORY NOTE PROVIDES FOR A BALLOON PAYMENT.

$250,000.00                                   Mountain View, California
                                              March 1, 1998

     For value received, the undersigned, LAVI A. LEV ("Employee") and SARAH LEV
(collectively, "Borrower"), promise to pay to SILICON GRAPHICS, INC., a Delaware
corporation ("SGI"), or order, at 2011 N. Shoreline Boulevard, Mountain View,
California 94043-1389, or such other place as SGI may designate in writing from
time to time, in lawful money of the United States of America, without
abatement, demand, deduction, setoff or counterclaim, the principal sum of Two
Hundred Fifty Thousand and 00/100 Dollars ($250,000.00). This Promissory Note
shall bear no interest, except as provided in Paragraph 4 below.

     1.   Payments
          --------

          (a) All outstanding principal and accrued interest under this
Promissory Note shall be due and payable on the Due Date (as defined below).
Interest shall be computed based upon a three hundred sixty (360) day year and
thirty (30) day month. Every payment received by SGI with respect to this
Promissory Note shall be applied as follows:  first, to the payment of any late
charges; second, to the payment of accrued but unpaid interest; and, third, to
the payment of the outstanding principal balance of this Promissory Note.
Borrower may prepay the principal amount outstanding under this Promissory Note
in whole or in part at any time without penalty.

          (b) Notwithstanding subparagraph 1(a) to the contrary, so long as
Employee remains employed by SGI on a regular and full-time basis, and provided
that Borrower has paid to SGI all outstanding principal and accrued interest
under that certain Promissory Note of even date herewith in the original
principal amount of $250,000 on or before March 1, 2002, Borrower's obligation
to pay principal under this Promissory Note shall be forgiven as follows:
principal in the amount of Two Hundred Fifty Thousand and 00/100 Dollars
($250,000.00) shall be forgiven on March 1, 2002.

          (c) Notwithstanding subparagraph 1(a) to the contrary, principal and
accrued interest under this Promissory Note shall be due and payable prior to
the Due Date to the extent of one hundred percent (100%) of the gross sales
proceeds payable to Borrower in connection with the sale of any Pledged
Collateral (as defined below); provided, however, that Borrower shall have the
right to exercise and/or sell Vested Shares (as defined in the Pledge Agreement)
to the 
<PAGE>
 
extent of the Excess Value (as defined in the Pledge Agreement) and
receive all proceeds therefrom. Notwithstanding the preceding to the contrary,
if SGI's employment of Employee shall terminate or cease for any reason, whether
voluntary or involuntary, and whether with or without cause, or Borrower shall
be in default hereunder, principal and accrued interest under this Promissory
Note shall be due and payable to the extent of one hundred percent (100%) of the
gross sales proceeds payable to Borrower in connection with the sale of any such
Pledged Collateral. In no event shall the preceding sentence be deemed to limit
SGI's recourse or Borrower's liability under this Promissory Note. Nothing
herein shall be deemed to modify the terms of any severance agreement now or
hereafter entered into by Employee and SGI.

          ---------------                                                     
this loan to Borrower for purposes of modifying the terms of an existing loan
("Existing Loan") provided by SGI to Borrower in connection with Employee's
relocation to the area of SGI's corporate headquarters located in Mountain View,
California. Borrower represents and warrants to SGI that Borrower has used all
proceeds of the Existing Loan to purchase Borrower's principal residence located
at 21771 Heber Way, Saratoga, California ("Residence"). The Existing Loan is
evidenced by a Promissory Note dated January 9, 1997 in the original principal
amount of $500,000, Deed of Trust with Assignment of Rents dated January 6, 1997
and Pledge Agreement dated January 9, 1997 (collectively, "Existing Loan
Documents"). Concurrently with the execution and delivery by Borrower of this

SGI to evidence the modification of the Existing Loan, SGI will cancel the
Existing Loan Documents.

     4.   Default. In the event that Borrower fails to timely pay any amount or
          -------                                                              
perform any other obligation of Borrower under this Promissory Note, the Pledge
Agreement (as defined below), that certain Promissory Note of even date herewith
in the original principal sum of $250,000, that certain Deed of Trust with
Assignment of Rents dated January 6, 1997, as amended, securing Borrower's
obligations under the immediately preceding promissory note, that certain Letter
Agreement of even date herewith, or any other agreement or instrument now or
hereafter executed by Borrower to evidence or secure the performance of
Borrowers obligations thereunder (collectively, "Loan Documents"), SGI may, at
its option, declare all principal and accrued interest under this Promissory
Note immediately due and payable. In the event that SGI exercises this option,
or the principal balance of this Promissory Note otherwise becomes due and
payable, all principal then outstanding under this Promissory Note shall
thereafter bear simple interest at the lesser of ten percent (10%) per annum or
the maximum rate permitted by law. Failure to exercise this option shall not
constitute a waiver of SGI's right to exercise the same with respect to any
prior or subsequent defaults.

secured by that certain Pledge Agreement of even date herewith ("Pledge
Agreement") encumbering certain stock options to acquire SGI common stock and
such other collateral described therein (collectively, "Pledged Collateral").

          ---------------                                                
required to enforce or interpret any provision of this Promissory Note, Borrower
shall pay to SGI upon demand all costs of collection and reasonable attorneys'
fees incurred by SGI in connection therewith.

     7.   Tax Liability. Borrower acknowledges that, upon forgiveness of
          -------------                                                 
Borrower's obligations under this Promissory Note pursuant to subparagraph 1(a)
above, SGI will provide to Borrower a one-time tax gross-up in connection with
the federal and state income tax liability of Borrower arising from such
forgiveness. Borrower agrees that this Promissory Note is personal to Borrower
and nontransferable, and is conditioned upon the future performance of
substantial services by Employee. Borrower certifies to SGI that Borrower
reasonably expects to itemize deductions for each year that principal is
outstanding under this Promissory Note.

     8.   Assignment to MIPS. Borrower acknowledges and agrees that this
          ------------------

          -------------                                                   
invalid or unenforceable for any reason, the same shall be ineffective, but the
remainder of this Promissory Note shall not be affected thereby and shall remain
in full force and effect.  Time is of the essence of each and every obligation
of Borrower hereunder. Presentment and demand for payment, notice of dishonor,
protest and notice of protest are hereby waived by Borrower. If the due date for
any payment under this Promissory Note falls on a Saturday, Sunday or legal
holiday, then such due date shall be extended to the next business day. None of
the terms or provisions of this Promissory Note may be waived, altered, modified
or amended except by a writing signed by SGI and Borrower. The provisions of
this Promissory Note shall be governed by California law. The covenants, terms
and conditions hereof shall bind the heirs, successors and assigns of Borrower
and shall inure to the benefit of the successors and assigns of SGI.

     NOW, THEREFORE, Pledgor hereby covenants and agrees as follows:

     1.   Pledge of Collateral.  Pledgor hereby pledges, assigns, grants and
          --------------------                                              
delivers to SGI a security interest in all of Pledgor's right, title and
interest in and to the following (collectively, "Pledged Collateral"):

                                       1
<PAGE>
 
          (a)  The SGI Option Agreement, all options and shares of common stock
of SGI now or hereafter issued or issuable to Pledgor thereunder and all cash
and non-cash proceeds and substitutions thereof as security for the prompt
performance of Pledgor's obligations under the Forgivable Note and Letter
Agreement.

          (b)  The MIPS Option Agreement, all options and shares of common stock
of MIPS now or hereafter issued or issuable to Pledgor thereunder and all cash
and non-cash proceeds and substitutions thereof as security for the prompt
performance of Pledgor's obligations under the Forgivable Note and Letter
Agreement. Upon the grant of options to Pledgor under the MIPS Option Agreement
and the execution and delivery by Pledgor of all agreements, documents and
instruments required by MIPS in connection therewith, the security interest in
the SGI Option Agreement and common stock of SGI shall automatically terminate.

     For purposes of this Agreement, "Option Agreement" shall mean the SGI
Option Agreement and/or MIPS Option Agreement, as applicable, and "Shares" shall
mean the shares of common stock of SGI and/or shares of common stock of MIPS, as
applicable.

     2.   Pledgor's Covenants.  Pledgor hereby represents, warrants and
          -------------------                                          
covenants to SGI as follows:

          (a)  The Pledged Collateral is free and clear of any security
interests, liens, encumbrances or other interests other than this Agreement.

          (b)  Pledgor has full power and authority to create a lien on the
Pledged Collateral in favor of SGI and no disability or contractual obligation
exists which would prohibit Pledgor from pledging the Pledged Collateral
pursuant to this Agreement.

          (c)  Pledgor shall not sell, assign, or create or permit any claim to,
lien or encumbrance upon, or security interest in any of the Pledged Collateral,
and shall not permit Pledgor's rights in the Pledged Collateral to be reached by
attachment, levy or other judicial process.

          (d)  At SGI's request, Pledgor shall execute and acknowledge such
other documents and instruments which SGI deems necessary or desirable to
evidence, continue or preserve SGI's security interest in the Pledged Collateral
and/or to otherwise effect any of the terms of this Agreement.

     The foregoing representations, warranties and covenants shall survive the
termination of this Agreement.

     3.   Payment of Proceeds.
          ------------------- 

          (a)  One hundred percent (100%) of all monies or other proceeds
payable

                                       2
<PAGE>
 
to Pledgor in connection with the sale or transfer of any Shares shall be
applied first to the payment of principal, accrued interest and other charges
then outstanding under the Forgivable Note; provided, however, that to the
extent that the fair market value (as determined pursuant to Section 5(a)(ii)
below) of Pledgor's vested and exercisable options and/or restricted stock
comprising the Shares (collectively, "Vested Shares") exceeds the sum of (i) the
amount of principal and accrued interest (if any) then outstanding under the
Forgivable Note plus (ii) the total contingent liability of Pledgor under the
Letter Agreement (such excess fair market value referred to herein as "Excess
Value"), Pledgor shall have the right to exercise and/or sell such Vested Shares
to the extent of such Excess Value and receive all proceeds therefrom. The
foregoing calculation shall be made for each transaction to be effected by
Pledgor with regard to any Vested Shares. Notwithstanding the preceding to the
contrary, if SGI's employment of Employee shall terminate or cease for any
reason, whether voluntary or involuntary, and whether with or without cause, or
Pledgor shall be in default hereunder, one hundred percent (100%) of all monies
or other proceeds payable to Pledgor in connection therewith shall be applied to
the payment of principal, accrued interest and other charges then outstanding
under the Forgivable Note. Further, if Employee shall terminate his employment
with SGI for any reason, SGI shall terminate Employee's employment with SGI for
cause, or Pledgor shall be in default hereunder, one hundred percent (100%) of
all monies or other proceeds payable to Pledgor in connection therewith shall be
applied to the payment of Pledgor's obligations under the Letter Agreement. Upon
Pledgor's payment to SGI of all principal, accrued interest and other charges
under the Forgivable Note and Letter Agreement (if applicable), the security
interest created under this Agreement shall automatically terminate, and SGI
shall promptly deliver to Pledgor all remaining Shares then held by SGI. Nothing
herein shall be deemed to modify the terms of any severance agreement now or
hereafter entered into by Employee and SGI.

          (b)  With respect to the concurrent exercise and disposition of Shares
by "Same Day Sale," Pledgor shall instruct Pledgor's stock broker ("Broker") to
pay directly to SGI from Broker's account an amount equal to the lesser of (i)
the gross proceeds from the sale of such Shares, less applicable commissions, to
the extent payable by Pledgor pursuant to subparagraph (a) above or (ii) the
amount of principal, accrued interest and other charges then outstanding under
the Forgivable Note and Letter Agreement (if applicable). SGI shall have no
obligation to deliver the Shares to Broker unless and until SGI receives written
confirmation from Broker that the foregoing payment shall be promptly made by
Broker to SGI.

          (c)  With respect to the exercise of Shares by "Cash Exercise," the
exercise price paid by Pledgor shall be applied to the payment of the exercise
price for such Shares, the applicable shares of SGI's common stock shall be
issued and deemed delivered to Pledgor, and SGI shall retain possession of such
shares until either (i) all principal, accrued interest and other charges under
the Forgivable Note and Letter Agreement (if applicable) have been paid in full,
in which event the security interest under this Agreement shall terminate as to
all of the Shares, or (ii) the applicable proceeds from the sale of such Shares
have been paid to SGI and applied to the payment of principal, accrued interest
and other charges then outstanding under the Forgivable 
                                       3
<PAGE>
 
Note and Letter Agreement (if applicable), in which event the security interest
under this Agreement shall terminate as to such Shares sold by Pledgor. If
Pledgor desires to sell any such Shares, Pledgor shall instruct Broker to pay
directly to SGI from Broker's account an amount equal to the lesser of (i) the
sales price of the Shares, less commissions, to the extent payable by Pledgor
pursuant to subparagraph (a) above or (ii) the amount of principal, accrued
interest and other charges then outstanding under the Forgivable Note and Letter
Agreement (if applicable). SGI shall have no obligation to deliver the Shares to
Pledgor or Broker unless and until SGI receives written confirmation from Broker
that the foregoing payment shall be promptly made by Broker to SGI.

          (d)  All instructions required to be submitted by Pledgor to Broker
shall be irrevocable and in writing, with a copy thereof delivered concurrently
to SGI. All proceeds paid for the Shares (less commissions) and otherwise
payable to SGI hereunder shall be deposited directly into the account of Broker
for payment to SGI. SGI's delivery of any Shares to Broker shall be for the sole
purpose of facilitating the sale of such Shares, and SGI's security interest
therein shall continue until Broker shall have paid to SGI all applicable sums
as required hereinabove.

     4.   Events of Default. Each of the following shall constitute an event of
          -----------------                                                    
default ("Event of Default") hereunder:

          (a)  The failure by Pledgor to observe or perform any of the
provisions of this Agreement.

          (b)  Any default under the Forgivable Note, the Letter Agreement or
any other document or instrument evidencing the modification of the Existing
Loan.

          (c)  The inaccuracy or breach of any warranty, representation or
statement made or furnished to SGI by or on behalf of Pledgor.

          (d)  The assignment for the benefit of creditors or the commencement
of any proceeding under any bankruptcy or insolvency law by or against Pledgor.

          (e)  The seizure or attachment of, or a levy on all or any portion of
the Pledged Collateral.

     5.   SGI's Remedies Upon Default.
          --------------------------- 

          (a)  Upon the occurrence of an Event of Default, SGI shall have the
right to:

               (i) Declare all of the obligations and liabilities of Pledgor
under the Forgivable Note and Letter Agreement immediately due and payable.

                                       4
<PAGE>
 
              (ii) Repurchase all or part of the Shares from Pledgor for a
purchase price equal to the lesser of (i) the fair market value of such Shares
as of the date of the Event of Default, or (ii) the fair market value of such
Shares as of the date of repurchase. The fair market value of the Shares, as of
any date, shall be the closing price for a share of SGI's common stock as
reported in The Wall Street Journal or a similar readily available public
source. If no sales of Shares were made on such date, the fair market value of
the Shares shall be determined using the closing price of a Share as reported
for the preceding day on which a sale of Shares occurred. Notwithstanding the
foregoing, the fair market value of any stock options comprising Shares shall be
determined using the fair market value of SGI's common stock as of the
applicable date set forth above less the applicable exercise price under such
stock options and any costs incurred by SGI pursuant to subparagraph (b) below.

             (iii) Exercise any and all rights of a secured party under the
Uniform Commercial Code of the State of California which SGI, in its sole
judgment, deems necessary or appropriate, including without limitation the right
to sell or otherwise dispose of all or any part of the Pledged Collateral.

          (b)  After the repurchase, sale or transfer of any of the Pledged
Collateral, SGI may deduct all reasonable attorneys' fees, brokerage commissions
and other expenses incurred by SGI in preserving, collecting, selling,
repurchasing and/or delivering the Pledged Collateral and for enforcing its
rights with respect to the Forgivable Note, the Letter Agreement and this
Agreement, and shall apply the residue of the proceeds to, or hold as a reserve
against, the Forgivable Note and Letter Agreement in such manner as SGI in its
reasonable discretion shall determine, and shall pay the balance, if any, to
Pledgor.

     6.   SGI's Duties.  SGI shall have no duty or liability for the Pledged
          ------------                                                      
Collateral except for the exercise of reasonable care of the Pledged Collateral
while in the possession of SGI.

     7.   General Provisions.
          ------------------ 

          (a)  Successors and Assigns.
               ---------------------- 

               (i)   This Agreement shall bind and insure to the benefit of the
respective heirs, successors and permitted assigns of each of the parties;
provided, however, that neither this Agreement nor any rights hereunder may be
assigned by Pledgor without SGI's prior written consent, which consent may be
granted or withheld in SGI's sole discretion.
   
               (ii)  Pledgor acknowledges and agrees that this Agreement may be
assigned by SGI to MIPS, in which event all references therein to SGI shall
automatically be amended and modified to mean and refer to "MIPS," all
obligations of SGI in connection with this Agreement shall automatically be
assumed by MIPS, and SGI shall automatically be released from any and all
liability to Pledgor in connection with this Agreement. Pledgor shall execute
such 
                                       5
<PAGE>
 
documents and instruments as may be requested by SGI to evidence the foregoing
within five (5) days following SGI's request therefor.

          (b)  Severability of Provisions.  Each provision of this Agreement
               --------------------------                                   
shall be severable from every other provision of this Agreement for the purpose
of determining the legal enforceability of any specific provision. In case one
or more of the provisions contained in this Agreement shall for any reason be
held invalid, illegal or unenforceable in any respect, the invalidity,
illegality or unenforceability of that provision shall not affect any other
provision of this Agreement.

          (c)  Joint and Several Obligations.  If Pledgor consists of more than
               -----------------------------                                   
one person, the obligations of Pledgor shall be the joint and several
obligations of all such persons. When the context and construction so require,
all words used in the singular herein shall be deemed to have been used in the
plural and the masculine shall include the feminine and neuter and vice versa.

          (d)  No Waiver.  No delay or omission by SGI in exercising any right
               ---------                                                      
or remedy arising from any default of Pledgor shall be construed as a waiver of
such default or as an acquiescence therein, nor shall any single or partial
exercise thereof preclude any further exercise thereof. SGI may, at its option,
waive any of the conditions herein and any such waiver shall not be deemed the
waiver of SGI's rights hereunder. The waiver of any Event of Default shall not
be construed as any waiver of or acquiescence in or consent to any preceding or
subsequent Event of Default by Pledgor hereunder.

          (e)  Collection Costs.  Pledgor shall promptly pay SGI all reasonable
               ----------------                                                
attomeys' fees and all costs and other expenses paid or incurred by SGI in
enforcing or exercising its rights or remedies created by, connected with or
provided in this Agreement, and payment thereof shall be secured by the Pledged
Collateral.

          (f) Substitute Security.  Provided that Pledgor is not in default
              -------------------                                          
hereunder, Pledgor shall have the right to substitute this Pledge Agreement with
such other security and/or collateral acceptable to SGI for purposes of securing
Pledgor's obligations under the Forgivable Note and Letter Agreement. Such
security may include, without limitation, a dead of trust encumbering real
property owned by Pledgor, provided that Pledgor's equity therein is in excess
of one hundred ten percent (110%) of the sum of the outstanding balance of
principal and accrued interest under the Forgivable Note and contingent
liability under the Letter Agreement. Following SGI's approval of the security
and receipt of such agreements and instruments (in form acceptable to SGI)
executed by Pledgor to effect such substitute security, SGI shall release the
lien of this Pledge Agreement with regard to the Pledged Collateral or portion
thereof so substituted.

IN WITNESS WHEREOF, this Pledge Agreement has been executed as of the Effective
Date.

                                         PLEDGOR:
