                                 PROXY STATEMENT

                       1997 ANNUAL MEETING OF SHAREHOLDERS
                                -----------------

                 INFORMATION CONCERNING SOLICITATION AND VOTING

General

         The enclosed  proxy is solicited on behalf of the Board of Directors of
Sierra  Semiconductor  Corporation (the "Company") for use at the Annual Meeting
of  Shareholders  of the  Company to be held on  Thursday,  June 5, 1997 at 3:00
p.m.,  local time, or at any  adjournments  thereof.  The Annual Meeting will be
held at the  Clarion  Hotel  Villa,  which is located at 4331  Dominion  Street,
Burnaby, British Columbia,  Canada. The Company's principal office is located at
2222 Qume  Drive,  San Jose,  California  95131.  Its  telephone  number at that
location is (408)  434-9300.  The Company's  principal  subsidiary is a Canadian
corporation named PMC-Sierra,  Inc. ("PMC").  References in this proxy statement
to "Sierra" or the Company" mean Sierra Semiconductor Corporation.
References to "PMC" mean Sierra's principal Canadian subsidiary.

         This proxy  statement is being mailed to shareholders on or about April
28, 1997.

Record Date and Share Ownership

         Only  holders  of Common  Stock of record at the close of  business  on
April 9, 1997 (the  "Record  Date")  are  entitled  to notice of and vote at the
Annual Meeting of  Shareholders.  At the Record Date,  29,152,950  shares of the
Company's Common Stock were issued and outstanding.

Shareholders' Proposals for 1998 Annual Meeting

         Proposals to be presented  by  shareholders  of the Company at the 1998
Annual  Meeting must be received by the Company no later than  December 27, 1997
in order  that they may be  included  in the proxy  statement  and form of proxy
relating to that meeting.

Revocability of Proxies

         Any proxy  given  pursuant to this  solicitation  may be revoked by the
person  giving it at any time before its use by (i)  delivering to the Company's
Secretary at 2222 Qume Drive,  San Jose,  California  95131, a written notice of
revocation or a duly executed  proxy bearing a later date or (ii)  attending the
meeting and voting in person.

Voting and Solicitation

         Each share of Common Stock  outstanding  on the Record Date is entitled
to one vote. In addition, every shareholder,  or the shareholder's proxy, who is
entitled to vote upon the election of directors may cumulate such  shareholder's
votes and give one  candidate a number of votes equal to the number of directors
to be elected  multiplied by the number of shares held by such  shareholder,  or
distribute  the  shareholder's  votes  on  the  same  principle  among  as  many
candidates as the shareholder may select, provided that votes cannot be cast for
more than six candidates. No shareholder or proxy, however, shall be entitled to
cumulate votes for a candidate  unless such  candidate's name has been placed in
nomination  prior to the voting and the shareholder,  or any other  shareholder,
has given  notice at the  meeting,  prior to the  voting,  of the  shareholder's
intention  to  cumulate  votes.  If  any  shareholder  gives  such  notice,  all
shareholders may cumulate their votes for candidates in nomination.
<PAGE>

         The six nominees  receiving the highest number of affirmative  votes of
the  shares  present or  represented  and  entitled  to vote shall be elected as
directors.  Approval of each other  matter  requires the  affirmative  vote of a
majority of the Votes Cast. For this purpose, the "Votes Cast" are defined under
California law to be the shares of the Company's  Common Stock  represented  and
voting in person or by proxy at the Annual Meeting. In addition, the affirmative
votes must  constitute  at least a majority of the required  quorum,  which is a
majority  of the  shares  outstanding  on the record  date.  Votes that are cast
against a proposal will be counted for purposes of determining  (i) the presence
or absence of a quorum and (ii) the total  number of Votes Cast with  respect to
the proposal.  While there is no  definitive  statutory or case law authority in
California as to the proper  treatment of  abstentions  in the counting of votes
with respect to a proposal,  the Company  believes  that  abstentions  should be
counted for purposes of determining both (i) the presence or absence of a quorum
and (ii) the total  number of Votes Cast with  respect to the  proposal.  In the
absence of controlling  precedent to the contrary,  the Company intends to treat
abstentions in this manner.  Accordingly,  abstentions will have the same effect
as a vote against the proposal. Broker non-votes will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business,
but will not be counted  for  purposes of  determining  the number of Votes Cast
with respect to a proposal.

         Votes  cast  by  proxy  or in  person  at the  Annual  Meeting  will be
tabulated by the Inspector of Elections (the "Inspector") with the assistance of
the Company's transfer agent. The Inspector will also determine whether a quorum
is present.

         The  cost of  soliciting  proxies  will be borne  by the  Company.  The
Company may retain the services of Boston  EquiServe,  L.P. to solicit  proxies,
for which the Company  estimates  that it would pay a fee not to exceed  $5,000,
plus out-of-pocket expenses. The Company may reimburse brokerage firms and other
persons  representing   beneficial  owners  of  shares  for  their  expenses  in
forwarding solicitation materials to such beneficial owners. Proxies may also be
solicited by certain of the Company's directors, officers and regular employees,
without additional compensation, in person or by telephone or facsimile.

         The following table sets forth certain information known to the Company
regarding  beneficial  ownership  of Common Stock of the Company as of March 15,

                                 PROPOSAL NO. 1:
                              ELECTION OF DIRECTORS

         The  Company's  Bylaws  provide  for a variable  board of four to seven
directors, with the number currently fixed at six. It is planned that a board of
six  directors  will  be  elected  at  the  Annual  Meeting.   Unless  otherwise
instructed, the proxy holders will vote the proxies received by them for the six
nominees  of the  Board of  Directors  named  below,  all of whom are  presently
directors  of the  Company.  If any  nominee is unable or declines to serve as a
director at the time of the Annual  Meeting,  the proxies  will be voted for any
nominee designated by the proxy holders to fill the vacancy.  It is not expected
that any  nominee  will be unable or will  decline  to serve as a  director.  If
shareholders  nominate persons other than the Company's nominees for election as
directors,  the  proxy  holders  will  vote  all  proxies  received  by  them in
accordance  with  cumulative  voting to assure  the  election  of as many of the
Company's  nominees as possible.  The term of office of each person elected as a
director will continue  until the next Annual Meeting of  Shareholders  or until
the director's successor has been elected.

         The Board of Directors recommends a vote FOR the nominees listed below:

Vote Required

         The  six  nominees  for  director   receiving  the  highest  number  of
affirmative  votes of the shares  entitled to be voted for them shall be elected
as  directors.  Votes  withheld  from any  director  are counted for purposes of
determining the presence or absence of a quorum,  but have no other legal effect
under California law.

Board Meetings and Committees

         The Board of Directors of the Company held six meetings during the 1996
fiscal year. All nominees who were Board members in 1996 attended 75% or more of
the meetings of the Board of  Directors  and of the  committees  of the Board on
which the  director  served (held during  their  membership  period)  except Dr.
Balkanski,  who attended two-thirds of the meetings.  The Board of Directors has
an Audit Committee, Compensation Committee and Stock Option Committee. The Board
does not have a nominating committee.

         The Audit  Committee,  which  consists of Mr. Dionne and Mr.  Marshall,
held one  meeting in 1996.  The Audit  Committee  recommends  engagement  of the
Company's independent auditors, approves the services performed by the Company's
independent  auditors and reviews the Company's  accounting  principles  and its
system of internal accounting controls.

compensation policy, bonus plans and equity incentive plans.

         The Stock Option Committee,  which consists of Mr. Diller and any other
one director,  took action by written  consent on several  occasions but did not
hold any meetings in 1996.  The Stock Option  Committee  has  authority to grant
stock  options to purchase  up to 10,000  shares to  individuals  not subject to
Section 16 of the Securities Exchange Act of 1934.

Board Compensation

         Non-employee  directors  receive an annual retainer of $12,000 per year
plus  $1,000 per board  meeting  attended  for their  services as members of the
Board of Directors, except for Mr. Marshall, who has waived his right to receive
this compensation.  Non-employee  directors are automatically granted options to
purchase shares of the Company's  Common Stock pursuant to the provisions of the
Company's 1994 Incentive Stock Plan. Mr. Marshall received an option to purchase
20,000  shares of Common  Stock at an exercise  price of $15.9375 per share upon
being  appointed  to the Board of  Directors  in April 1996.  In June 1996,  Mr.
Balkanski  and Mr. Dionne each  received  automatic  annual grants of options to
purchase  5,000 shares of Common Stock at an exercise price of $14.50 per share.
Mr. Beaumont  received an option to purchase 20,000 shares of common stock at an
exercise  price of  $15.8125  per share  upon  being  appointed  to the Board of
Directors  in April 1997.  These  options  become  exercisable  as to 1/4 of the
shares  subject to the  option  after one year;  thereafter,  1/48 of the shares
subject to the option become exercisable at the end of each calendar month.

         The Company  has agreed to  indemnify  each  director  against  certain
claims and expenses for which the  director  might be held liable in  connection
with past or future service on the Board. In addition,  the Company maintains an
insurance policy insuring its officers and directors against such liabilities.

Certain Transactions

         During  the year  ended  December  29,  1996,  members  of the Board of
Directors of the Company and executive  officers of the Company  received grants
of options as set forth under "Board Compensation" and "Executive Compensation."

         During 1996 Mr.  Bailey,  a director  and an  executive  officer of the
Company,  had an  outstanding  loan from PMC pursuant to a September 1994 credit
facility established to pay certain tax expenses incurred in connection with the
transfer of PMC Special Shares to his wife. The maturity date of the loan is the
earlier  of (i)  August 1, 1999 or (ii) when  certain  designated  shares of the
Company's  Common  Stock held by Mr.  Bailey are  disposed of in an arm's length
transaction.  The interest rate of the loan is the higher of (i) the  applicable
U.S.  federal rate for a five-year loan or (ii) the prescribed rate for employee
loans  pursuant to the Income Tax Act (Canada).  During 1996 PMC  reimbursed Mr.
Bailey for  interest  paid on the loan.  During  1996,  the largest  outstanding
amount owed by Mr. Bailey to PMC was approximately  $344,198. This loan was paid
in full in December 1996.

         In January  1996,  in  connection  with the sale of SiTel  Sierra  B.V.
("SiTel"),  Mr.  Diller,  the  Chairman  of the  Board of  Directors  and  Chief
Executive Officer of the Company,  received  approximately $80,000 upon the sale
of his SiTel shares upon  substantially the same terms as all other shareholders
of SiTel including the Company (which received approximately $7 million).

Section 16(a) Reports

         Section 16(a) of the Exchange Act requires the  Company's  officers and
directors,  and  persons  who own  more  than 10% of a  registered  class of the
Company's equity securities, to file certain reports regarding ownership of, and
transactions  in, the  Company's  Securities  with the  Securities  and Exchange
Commission (the "SEC").  Such officers,  directors and 10% shareholders are also
required by SEC rules to furnish the  Company  with copies of all Section  16(a)
forms that they file.
<PAGE>

         Based solely on its review of the copies of such forms  received by it,
or written  representations from certain reporting persons, the Company believes
that during  fiscal 1996 all the reporting  persons  complied with Section 16(a)
filing  requirements except that in December 1996 Mr. Bailey reported the
acquisition  earlier in the year  of Common Stock of the Company upon redemption
of PMC Series 1-A and Series 1-B Special Shares.

                                 PROPOSAL NO. 2:
                           REINCORPORATION IN DELAWARE

Introduction

         The Board of Directors  believes that the best interests of the Company
and its  shareholders  will be served by changing the state of  incorporation of
the Company from  California to Delaware (the  "Reincorporation").  As discussed
below,  the  principal  reasons for  reincorporation  are the  reduction  in the
Company's  operations  in  California,   the  greater  flexibility  of  Delaware
corporate law, the substantial  body of case law  interpreting  that law and the
increased ability of the Company to attract and retain qualified directors.  The
proposed  Delaware  certificate of  incorporation  and bylaws are  substantially
similar to those  currently in effect in California with the exceptions that (i)
cumulative voting will be eliminated as part of the  Reincorporation if Proposal
No. 4 is approved by the  shareholders  of the Company,  and (ii) the ability of
the  shareholders  to act by written  consent will be  eliminated as part of the
Reincorporation if Proposal No. 5 is approved by the shareholders of the Company
 . The term "Sierra Delaware" refers to the new Delaware corporation which is the
proposed  successor  to the Company.  Proposal No. 3 would change the  Company's
name  to  "PMC-Sierra,  Inc."  If  Proposals  No.  2 and 3 are  approved  by the
shareholders  of the  Company,  the name  change will be effected as part of the
Reincorporation.

         The Reincorporation will be effected by merging the Company into Sierra
Delaware (the "Merger").  Upon completion of the Merger,  the Company will cease
to exist and Sierra  Delaware  will  continue  to operate  the  business  of the
Company.  Pursuant to the Agreement  and Plan of Merger  between the Company and
Sierra  Delaware,  a copy of which is attached  hereto as Exhibit A (the "Merger
Agreement"),  each outstanding  share of the Company Common Stock, no par value,
will  automatically be converted into one share of Sierra Delaware Common stock,
no par value.  IT IS NOT NECESSARY FOR  SHAREHOLDERS  TO EXCHANGE THEIR EXISTING
STOCK CERTIFICATES FOR STOCK CERTIFICATES OF SIERRA DELAWARE.

         Upon the date on which the Merger will become effective (the "Effective
Date"),  Sierra  Delaware  will also assume and continue the  outstanding  stock
options and all other employee  benefit plans of the Company.  Each  outstanding
and unexercised option or other right to purchase shares of the Company's Common
Stock will  become an option or right to  purchase  the same number of shares of
Sierra  Delaware  Common Stock on the same terms and  conditions and at the same
exercise  price  applicable  to any  such  the  Company  option  or right at the
Effective Date.

         The  Reincorporation  has been  unanimously  approved by the  Company's
Board of  Directors.  If  approved by the  shareholders  of the  Company,  it is
anticipated  that the Effective Date of the Merger will be as soon as reasonably
practicable following the Annual Meeting of Shareholders.  However,  pursuant to
the Merger Agreement, the Merger may be abandoned or the Merger Agreement may be
amended by the Board of Directors  (except that certain  principal terms may not
be amended  without  shareholder  approval)  either before or after  shareholder
approval   has  been   obtained  and  prior  to  the   Effective   Date  of  the
Reincorporation  if, in the opinion of the board of directors of either company,
circumstances arise that make it inadvisable to proceed.

         Shareholders  of  the  Company  will  have  no  dissenters'  rights  of
appraisal  with respect to the  Reincorporation.  See  "Significant  Differences
Between the Corporation Laws of California and Delaware--Appraisal  Rights." The
discussion  set forth below is  qualified  in its  entirety by  reference to the
Merger  Agreement,  the  Certificate of  Incorporation  and the Bylaws of Sierra
Delaware,  copies  of  which  are  attached  hereto  as  Exhibit  A,  B  and  C,
respectively.
<PAGE>

Vote Required for the Reincorporation Proposal

         Approval of the  Reincorporation  will require the affirmative  vote of
the  holders of a majority of the  outstanding  shares of the  Company's  Common
Stock,  and will also  constitute  approval  of the (i)  Merger  Agreement,  and
Certificate of  Incorporation  and Bylaws of Sierra Delaware (which will use the
corporate  name  PMC-Sierra,  Inc. if the  shareholders  of the Company  approve
Proposal No. 3, provide for elimination of cumulative voting if the shareholders
of  the  Company  approve  Proposal  No.  4,  and  provide  for  elimination  of
shareholders'  action by written  consent  if the  shareholders  of the  Company
approve  Proposal No.5),  (ii) the assumption of the Company's  employee benefit
plans and  outstanding  stock options by Sierra  Delaware and (iii) revisions in
the  Company's  indemnification  agreements  with its officers and  directors to
conform those agreements to Delaware law.

         THE BOARD  RECOMMENDS  A VOTE  "FOR" THE  PROPOSED  REINCORPORATION  IN
DELAWARE.  THE EFFECT OF AN ABSTENTION IS THE SAME AS THAT OF A VOTE AGAINST THE
REINCORPORATION.

Principal Reasons for the Reincorporation

         The Company has remained a California  corporation  since its inception
due in part to the large proportion of its operations in California. As a result
of the Company's exit from the modem chipset business and related  restructuring
of  its   non-networking   product   businesses   announced  in  September  1996
("Restructuring"),  the  Company's  California  operations  will  become a small
portion of its total operations. As a result, the Board of Directors believes it
is appropriate to take advantage of the following benefits of Delaware law.

         Prominence,  Predictability  and  Flexibility of Delaware Law. For many
years Delaware has followed a policy of encouraging  incorporation  in that sate
and, in  furtherance of that policy,  has been a leader in adopting,  construing
and implementing comprehensive,  flexible corporate laws responsive to the legal
and  business  needs of  corporations  organized  under  its  laws.  Because  of
Delaware's prominence as the state of incorporation for many major corporations,
both the legislature  and courts in Delaware have  demonstrated an ability and a
willingness to act quickly and effectively to meet changing  business needs. The
Delaware courts have developed  considerable expertise in dealing with corporate
issues and a substantial body of case law has developed  construing Delaware law
and establishing public policies with respect to corporate legal affairs.

         Increased  Ability to  Attract  and Retain  Qualified  Directors.  Both
California  and Delaware law permit a corporation  to include a provision in its
certificate of incorporation  which reduces or limits the monetary  liability of
directors  for  breaches  of  fiduciary  duty  in  certain  circumstances.   The
increasing  frequency of claims and litigation  directed  against  directors and
officers  has  greatly  expanded  the risks  facing  directors  and  officers of
corporations in exercising their respective duties. The amount of time and money
required  to  respond  to such  claims  and to  defend  such  litigation  can be
substantial.  Recent efforts to adopt legislation in California,  if successful,
would have increased the liability of directors.  It is the Company's  desire to
reduce these risks to its  directors  and officers  and to limit  situations  in
which monetary  damages can be recovered  against  directors so that the Company
may continue to attract and retain  qualified  directors who otherwise  might be
unwilling to serve because of the risks involved.  The Company believes that, in
general,  Delaware law provides greater  protection to directors than California
law and that  Delaware  case law  regarding  a  corporation's  ability  to limit
director  liability is more developed and provides more guidance than California
law.

         Well-Established   Principles   of  Corporate   Governance.   There  is
substantial  judicial precedent in the Delaware courts as to the legal principle
applicable to measures that may be taken by a corporation  and as to the conduct
of the Board of Directors under the business judgment rule. The Company believes
that its  shareholders  will benefit  from the  well-established  principles  of
corporate governance that Delaware law affords.
<PAGE>

No Change in the Board Members, Business, Management, Employee Plans or Location
of Principal Facilities of the Company

         The  Reincorporation  will effect a change in the legal domicile of the
Company,  but not its physical location.  The Reincorporation will not result in
any change in the business,  management,  fiscal year,  assets or liabilities or
location of the  principal  facilities of the Company.  The Company's  principal
business activities will be conducted in Canada as a result of the Restructuring
and not as a result of the Reincorporation.  The Company's directors will become
the directors of Sierra Delaware. All employee benefit plans of the Company will
be assumed and continued by Sierra  Delaware.  All stock options or other rights
to acquire Common Stock of the Company will  automatically  be converted into an
option or right to purchase the same number of shares of Sierra  Delaware Common
Stock at the same price per share,  upon the same terms, and subject to the same
conditions.  The Company's  other  employee  benefit  arrangements  will also be
continued  by  Sierra  Delaware  upon the terms and  subject  to the  conditions
currently in effect.

Antitakeover Implications

         Delaware,  like many other  states,  permits a  corporation  to adopt a
number of measures  through  amendment of the  certificate of  incorporation  or
bylaws or  otherwise,  which  measures  are  designed to reduce a  corporation's
vulnerability to unsolicited takeover attempts. The Reincorporation is not being
proposed  in order to  prevent an  unsolicited  takeover  attempt,  nor is it in
response  to any  present  attempt  known to the Board of  Directors  to acquire
control of the Company,  obtain representation on the Board of Directors or take
significant action that affects the Company.

         Certain  effects  of the  Reincorporation  may be  considered  to  have
antitakeover  implications.  Section 203 of the Delaware General Corporation Law
("Section  203"),  from which Sierra  Delaware does not currently  intend to opt
out, restricts certain "business  combinations"  with "interested  stockholders"
for three years following the date that a person or entity becomes an interested
stockholder,  unless the Board of Directors  approves  the business  combination
and/or other  requirements are met. Other measures permitted under Delaware law,
which  the  Company  does  not  presently  intend  to  implement,   include  the
establishment  of a staggered  board of directors,  and the  elimination  of the
right of  stockholders  controlling  at least ten  percent  (10%) of the  voting
shares to call a special meeting of stockholders.  For a detailed  discussion of
all  of  the  changes  that  will  be   implemented  as  part  of  the  Proposed
Reincorporation,  see  "The  Charters  and  Bylaws  of the  Company  and  Sierra
Delaware."  For a discussion of  differences  between the laws of California and
Delaware,   see  "Significant   Differences  Between  the  Corporation  Laws  of
California and Delaware."

         In addition,  Delaware Law permits a corporation to adopt such measures
as stockholder rights plan, designed to reduce a corporation's  vulnerability to
unsolicited  takeover attempts.  There is substantial  judicial precedent in the
Delaware courts as to the legal principles applicable to such defensive measures
and as to the conduct of a board of directors  under the business  judgment rule
with respect to  unsolicited  takeover  attempts.  The Board of Directors has no
present  intention  following the  Reincorporation  to amend the  Certificate of
Incorporation  or Bylaws to include  provisions  that might deter an unsolicited
takeover attempt.  However, in the discharge of its fiduciary obligations to its
shareholders,  the Board of Directors  of the Company will  continue to evaluate
the Company's vulnerability to potential unsolicited bids to acquire the Company
on unfavorable  terms and to consider  strategies to enhance the Board's ability
to negotiate with an unsolicited bidder.
<PAGE>
The Charters and Bylaws of the Company and Sierra Delaware

         The provisions of the Sierra Delaware  Certificate of Incorporation and
Bylaws are  similar to those of the  Company's  Articles  of  Incorporation  and
Bylaws  in  many   respects.   However,   the   Reincorporation   includes   the
implementation  of certain  provisions  in the Sierra  Delaware  Certificate  of
Incorporation and Bylaws that alter the rights of shareholders and the powers of
management.  In addition,  Sierra Delaware could implement certain other changes
by amending its  Certificate of  Incorporation  and Bylaws.  For a discussion of
such changes,  see below and  "Significant  Differences  Between the Corporation
Laws of California and Delaware."

         The Articles of  Incorporation of the Company  currently  authorize the
Company to issue up to 50,000,000 shares of Common Stock, no par value,  405,916
shares of Series D  Preferred  Stock,  no par  value,  and  5,000,000  shares of
undesignated  Preferred  Stock,  no par value.  The shares of Series D Preferred
Stock were authorized before the Company's initial public offering. There are no
outstanding  shares of Series D Preferred Stock and the Company has no intention
of  issuing  Series  D  Preferred   Stock.   Accordingly,   the  Certificate  of
Incorporation of Sierra Delaware provides that such company will have 50,000,000
authorized  shares  of Common  Stock,  no par  value,  and  5,000,000  shares of
undesignated  Preferred  Stock,  no par value.  Like the  Company's  Articles of
Incorporation,  Sierra Delaware's Certificate of Incorporation provides that the
Board of Directors is entitled to determine the powers,  preferences and rights,
and the  qualifications,  limitations  or  restrictions,  of the  authorized and
unissued  undesignated  Preferred  Stock.  Thus,  although  it  has  no  present
intention of doing so, the Board of  Directors,  without  stockholder  approval,
could  authorize the issuance of Preferred Stock upon terms which could have the
effect of delaying or preventing a change in control of the Company or modifying
the rights of holders of the Company's  Common Stock under either  California or
Delaware  law.  The  Board of  Directors  could  also  use  shares  for  further
financings, possible acquisitions and other uses.

         Monetary  Liability of Directors.  The Articles of Incorporation of the
Company and the Certificate of Incorporation of Sierra Delaware both provide for
the  elimination  of personal  monetary  liability  of  directors to the fullest
extent permissible under the applicable law. The provisions eliminating monetary
liability  of  directors  set  forth  in  the  Sierra  Delaware  Certificate  of
Incorporation  is potentially  broader than the  corresponding  provision in the
Company's  Articles of  Incorporation,  in that the former  incorporates  future
amendments to Delaware law with respect to the  elimination  of such  liability.
See  "Significant  Differences  Between the  Corporation  Laws of California and
Delaware--Indemnification and Limitation of Liability."

         Size of the Board of Directors.  The Bylaws of Sierra Delaware  provide
for a Board of Directors consisting of six directors.  The Bylaws of the Company
provide for a Board of Directors of from four to seven  members,  with the exact
number currently set at six directors. Under California law, although changes in
the number of  directors,  in  general,  must be  approved  by a majority of the
outstanding  shares,  the Board may fix the exact number of  directors  within a
stated range set forth in the articles of incorporation or bylaws.  Delaware law
permits the board of directors, acting alone, to change the authorized number of
directors by amendment to the bylaws, unless the directors are not authorized to
amend the  bylaws or the  number of  directors  is fixed in the  certificate  of
incorporation.  After  the  Reincorporation,  the Board of  Directors  of Sierra
Delaware  could  amend the Bylaws to change  the size of the Board of  Directors
from six directors without further stockholder approval.

         Cumulative   Voting  for  Directors.   Under  California  law,  if  any
shareholder  has given notice of an intention to cumulate votes for the election
of  directors,  any other  shareholder  of the  corporation  is also entitled to
cumulate his or her votes at such election. Cumulative voting provides that each
share of stock  normally  having one vote is entitled to a number of votes equal
to the number of directors to be elected.  A shareholder  may then cast all such
votes for a single  candidate or may allocate  them among as many  candidates as
the shareholder may choose. In the absence of cumulative  voting, the holders of
a majority of the shares present or represented at a meeting in which  directors
<PAGE>
are to be elected  would have the power to elect all the directors to be elected
at such meeting,  and no person could be elected  without the support of holders
of a majority of the shares present or represented at such meeting.  Elimination
of cumulative  voting could make it more  difficult  for a minority  shareholder
adverse  to a  majority  of the  shareholders  to obtain  representation  on the
Company's Board of Directors. California corporations whose stock is listed on a
national stock exchange or whose stock is held by 800 shareholders of record and
included in the Nasdaq  National  Market  System (a "Listed  Company")  can also
eliminate cumulative voting with shareholder approval.  The Company qualifies as
a Listed Company but has not sought shareholder approval to eliminate cumulative
voting.  Under Delaware law,  cumulative  voting in the election of directors is
not mandatory. The Sierra Delaware Certificate of Incorporation will not provide
for cumulative voting rights if the shareholders of the Company approve Proposal
No. 4.

         Power to Call Special Shareholders'  Meetings.  Under California law, a
special  meeting of  shareholders  may be called by the Board of Directors,  the
Chairman of the Board, the President, the holders of shares entitled to cast not
less than 10% of the votes at such  meeting and such  additional  persons as are
authorized by the articles of incorporation or the bylaws. Under Delaware law, a
special  meeting of  stockholders  may be called by the Board of Directors or by
any other person  authorized to do so in the Certificate of Incorporation or the
Bylaws.  The  Bylaws  of  Sierra  Delaware  currently  authorize  the  Board  of
Directors,  the Chairman of the Board, the President and the holders of not less
than  10%  of  the  shares  entitled  to  vote  to  call a  special  meeting  of
stockholders.   Therefore,   no  substantive  change  is  contemplated  in  this
provision,  although  the Board could in the future amend the  Company's  Bylaws
without stockholder approval.

         Filling Vacancies on the Board of Directors.  Under California law, any
vacancy  on the board of  directors  other  than one  created  by  removal  of a
director  may be filled by the Board.  If the number of directors is less than a
quorum,  a  vacancy  may be  filled  by the  unanimous  written  consent  of the
directors then in office, by the affirmative vote of a majority of the directors
at a meeting held pursuant to notice or waivers of notice or by a sole remaining
director.  A vacancy created by removal of a director may be filled by the board
only if so authorized by a corporation's articles of incorporation or by a bylaw
approved by the  corporation's  shareholders.  The Company's current Articles of
Incorporation  and Bylaws do not permit  directors to fill vacancies  created by
removal  of  a  director.  Under  Delaware  law,  vacancies  and  newly  created
directorships  may be filled by a majority of the directors then in office (even
though less than a quorum) or by a sole  remaining  director,  unless  otherwise
provided  in  the  certificate  of   incorporation  or  bylaws  (or  unless  the
certificate  of  incorporation  directs that a  particular  class of stock is to
elect such directors), in which case a majority of the directors elected by such
class, or a sole remaining director so elected, shall fill such vacancy or newly
created  directorship).  The Bylaws of Sierra Delaware provide,  consistent with
the Company's  Bylaws,  that any vacancy created by the removal of a director by
the  stockholders  of Sierra  Delaware  may be filled only by the  stockholders.
Following the  Reincorporation,  the Board of Directors of Sierra Delaware could
amend the Bylaws to  provide  that  directors  may fill any  vacancy  created by
removal of directors by the stockholders.

         Loans to Officers  and  Employees.  Under  California  law, any loan or
guaranty to or for the benefit of a director  or officer of the  corporation  or
its parent requires approval of the shareholders unless such loan or guaranty is
provided  under  a plan  approved  by  shareholders  owning  a  majority  of the
outstanding   shares  of  the  corporation.   However,   under  California  law,
shareholders of any corporation with 100 or more shareholders of record, such as
the Company,  may approve a bylaw  authorizing  the board of directors  alone to
approve  loans or  guaranties  to or on behalf of officers  (whether or not such
officers are directors) if the board  determines  that any such loan or guaranty
may  reasonably be expected to benefit the  corporation.  Pursuant to the Sierra
Delaware  Bylaws and in accordance  with Delaware law,  Sierra Delaware may make
loans to, guarantee the obligations of or otherwise assist its officers or other
employees  and  those  of its  subsidiaries  (including  directors  who are also
officers or employees) when such action,  in the judgment of the directors,  may
reasonably be expected to benefit the corporation.

         Voting  by  Ballot.  California  law  provides  that  the  election  of
directors may proceed in the manner  described in a  corporation's  bylaws.  The
Company's   current   Bylaws  provide  that  the  election  of  directors  at  a
shareholders'  meeting may be by voice vote or ballot, unless prior to such vote
a  shareholder  demands  a vote by  ballot,  in which  case such vote must be by
ballot.  Under  Delaware  law,  the  right  to vote  by  written  ballot  may be
restricted if so provided in the  Certificate  of  Incorporation.  The Bylaws of
Sierra  Delaware  do not  address  election by ballot,  but the  Certificate  of
Incorporation of Sierra Delaware,  consistent with the Company's current Bylaws,
provides that if a  stockholder  specifically  demands  election of directors by
ballot  (or if the  Bylaws  provide  that  elections  shall be by  ballot)  then
elections shall be held by ballot. Stockholders of Sierra Delaware may therefore
continue  to demand  election  by ballot,  unless and until the  Certificate  of
Incorporation is amended,  which amendment would require a majority  stockholder
vote. It may be more  difficult  for a  stockholder  to contest the outcome of a
vote that has not been conducted by written ballot.

Compliance with Delaware and California Law

         Following the Annual Meeting of Shareholders, if the Reincorporation is
approved,  the  Company  will submit the Merger  Agreement  to the office of the
California  Secretary  of State and to the office of the  Delaware  Secretary of
State for filing.

Significant Differences Between the Corporation Laws of California and  Delaware

         The  corporation  laws  of  California  and  Delaware  differ  in  many
respects.  Although  all  the  differences  are  not set  forth  in  this  Proxy
Statement,  certain  provisions,  which  could  materially  affect the rights of
shareholders, are discussed below.

         Stockholder Approval of Certain Business Combinations. In recent years,
a number of states have adopted  special laws  designed to make certain kinds of
"unfriendly" corporate takeovers,  or other transactions involving a corporation
and one or more of its significant shareholders,  more difficult.  Under Section
203, certain "business combinations" with "interested  stockholders" of Delaware
corporations are subject to a three-year  moratorium unless specified conditions
are met.

         Section  203  prohibits  a  Delaware  corporation  from  engaging  in a
"business  combination"  with  an  "interested   stockholder"  for  three  years
following the date that such person or entity becomes an interested stockholder.
With certain exceptions,  an interested stockholder is a person or entity who or
which owns,  individually  or with or through certain other persons or entities,
15% or more of the corporation's  outstanding voting stock (including any rights
to acquire  stock  pursuant to an option,  warrant,  agreement,  arrangement  or
understanding,  or upon the exercise of conversion or exchange rights, and stock
with respect to which the person has voting rights only),  or is an affiliate or
associate of the corporation and was the owner,  individually or with or through
certain  other  persons or entities,  of 15% or more of such voting stock at any
time within the previous three years,  or is an affiliate or associate of any of
the foregoing.

         For purposes of Section 203, the term "business combination" is defined
broadly to include mergers with or caused by the interested  stockholder;  sales
or other dispositions to the interested stockholder (except proportionately with
the corporation's  other  stockholders) of assets of the corporation or a direct
or indirect majority-owned  subsidiary equal in aggregate market value to 10% or
more of the  aggregate  market  value of either the  corporation's  consolidated
assets  or all  of its  outstanding  stock;  the  issuance  or  transfer  by the
corporation  or a direct or indirect  majority-owned  subsidiary of stock of the
corporation  or such  subsidiary  to the  interested,  stockholder  (except  for
certain  transfers in a  conversion  or exchange or a pro rata  distribution  or
certain other transactions,  none of which increase the interested stockholder's
proportionate  ownership  of any class or series  of the  corporation's  or such
subsidiary's  stock or of the  corporation's  voting  stock);  or receipt by the
interested  stockholder (except  proportionately as a stockholder),  directly or
indirectly,  of any loans,  advances,  guarantees,  pledges  or other  financial
benefits provided by or through the corporation or a subsidiary.
<PAGE>

         The three-year  moratorium imposed on business  combinations by Section
203 does not apply if: (i) prior to the date on which such  stockholder  becomes
an interested  stockholder  the board of directors  approves either the business
combination or the transaction that resulted in the person or entity becoming an
interested stockholder;  (ii) upon consummation of the transaction that made him
or her an interested  stockholder,  the interested stockholder owns at least 85%
of the  corporation's  voting  stock  outstanding  at the time  the  transaction
commenced  (excluding from the 85% calculation shares owned by directors who are
also officers of the target  corporation and shares held by employee stock plans
that do not  give  employee  participants  the  right to  decide  confidentially
whether  to accept a tender or  exchange  offer);  or (iii) on or after the date
such person or entity becomes an interested stockholder,  the board approves the
business combination and it is also approved at a stockholder meeting by 66-2/3%
of the outstanding voting stock not owned by the interested stockholder.

         Section 203 only applies to certain  publicly  held  corporations  that
have a class  of  voting  stock  that is (i)  listed  on a  national  securities
exchange,  (ii)  quoted  on an  interdealer  quotation  system  of a  registered
national  securities  association  or (iii)  held of record  by more than  2,000
stockholders.  Although a Delaware  corporation to which Section 203 applies may
elect not to be governed by Section 203,  Sierra  Delaware does not intend to so
elect.

         Section 203 will encourage any potential acquiror to negotiate with the
Company's Board of Directors. Section 203 also might have the effect of limiting
the ability of a potential acquiror to make a two-tiered bid for Sierra Delaware
in which all  stockholders  would not be treated  equally.  Shareholders  should
note,  however,  that the  application  of Section 203 to Sierra  Delaware  will
confer  upon the Board the power to reject a proposed  business  combination  in
certain  circumstances,  even  though a  potential  acquiror  may be  offering a
substantial  premium for Sierra Delaware's  shares over the then-current  market
price.  Section 203 would also discourage certain potential  acquirers unwilling
to comply with its provisions. See "Shareholder Voting".

         Removal of Directors.  Under California law, any director or the entire
board of directors may be removed, with or without cause, with the approval of a
majority of the  outstanding  shares  entitled to vote;  however,  no individual
director  may be removed  (unless the entire  board is removed) if the number of
votes cast against such removal would be sufficient to elect the director  under
cumulative voting. Under Delaware law, a director of a corporation that does not
have a classified board of directors or cumulative voting may be removed with or
without cause with the approval of a majority of the outstanding shares entitled
to vote at an  election  of  directors.  In the case of a  Delaware  corporation
having  cumulative  voting,  if less than the entire  board is to be removed,  a
director may not be removed  without cause if the number of shares voted against
such removal would be sufficient to elect the director under cumulative  voting.
A director of a corporation  with a classified board of directors may be removed
only for cause, unless the certificate of incorporation  otherwise provides. The
Certificate  of  Incorporation  of  Sierra  Delaware  does  not  provide  for  a
classified  board of directors.  The Delaware rule for removal of directors in a
corporation with cumulative voting will apply if the shareholders of the Company
do not approve Proposal No. 4.

         Classified  Board of  Directors.  A classified  board is one on which a
certain  number,  but not all, of the directors are elected on a rotating  basis
each year. This method of electing directors makes changes in the composition of
the board of directors more difficult, and thus a potential change in control of
a corporation a lengthier and more  difficult  process.  California  law permits
certain  qualifying  corporations to provide for a classified board of directors
by adopting  amendments  to their  articles of  incorporation  or bylaws,  which
amendments must be approved by the shareholders.  Although the Company qualifies
to adopt a classified  board of  directors,  its Board of Directors has not done
so. Delaware law permits, but does not require, a classified board of directors,
pursuant to which the  directors  can be divided  into as many as three  classes
with staggered  terms of office,  with only one class of directors  standing for
election each year. The Sierra Delaware  Certificate of Incorporation and Bylaws
do not provide for a classified  board and Sierra  Delaware  presently  does not
intend to propose  establishment of a classified  board. The  establishment of a
classified board following the Reincorporation would require the approval of the
stockholders of Sierra Delaware.

         Indemnification  and  Limitation of Liability.  California and Delaware
have similar laws respecting  indemnification  by a corporation of its officers,
directors, employees and other agents. The laws of both states also permit, with
certain  exceptions,  a  corporation  to adopt a  provision  in its  articles of
incorporation or certificate of incorporation,  as the case may be,  eliminating
the liability of a director to the corporation or its  shareholders for monetary
damages  for breach of the  director's  fiduciary  duty.  There are  nonetheless
certain   differences   between   the   laws  of  the  two   states   respecting
indemnification and limitation of liability.

         The Articles of Incorporation of the Company eliminate the liability of
directors to the corporation to the fullest extent  permissible under California
law.  California law does not permit the elimination of monetary liability where
such liability is based on: (a)  intentional  misconduct or knowing and culpable
violation of law; (b) acts or omissions that a director  believes to be contrary
to the best interests of the  corporation or its  shareholders,  or that involve
the  absence  of good  faith  on the part of the  director;  (c)  receipt  of an
improper  personal benefit;  (d) acts or omissions that show reckless  disregard
for the  director's  duty to the  corporation  or its  shareholders,  where  the
director in the ordinary  course of  performing a  director's  duties  should be
aware of a risk of serious injury to the  corporation or its  shareholders;  (e)
acts or omissions  that  constitute  an unexcused  pattern of  inattention  that
amounts to an  abdication  of the  director's  duty to the  corporation  and its
shareholders; (f) interested transactions between the corporation and a director
in which a director has a material  financial  interest;  and (g)  liability for
improper distributions, loans or guarantees.

         The Certificate of Incorporation of Sierra Delaware also eliminates the
liability of  directors  to the  corporation  or its  stockholders  for monetary
damages  for  breach of  fiduciary  duty as a  director  to the  fullest  extent
permissible  under  Delaware  law, as such law exists  currently or as it may be
amended in the future.  Under  Delaware law, such provision may not eliminate or
limit director  monetary  liability for: (a) breaches of the director's  duty of
loyalty to the  corporation  or its  stockholders;  (b) acts or omissions not in
good faith or involving intentional misconduct or knowing violations of law; (c)
the payment of unlawful  dividends or unlawful stock repurchases or redemptions;
or (d) transactions in which the director received an improper personal benefit.
Such  limitation  of  liability  provisions  also  may not  limit  a  director's
liability  for  violation  of,  or  otherwise  relieve  Sierra  Delaware  or its
directors from the necessity of complying with federal or state securities laws,
or affect the availability of non-monetary remedies such as injunctive relief or
rescission.

         California  law  permits   indemnification   of  expenses  incurred  in
derivative  or  third-party  actions,  except  that with  respect to  derivative
actions (a) no  indemnification  may be made when a person is adjudged liable to
the  corporation in the performance of that person's duty to the corporation and
its shareholders  unless a court determines such person is entitled to indemnity
for expenses,  and then such indemnification may be made only to the extent that
such court shall determine, and (b) no indemnification may be made without court
approval  in  respect  of amounts  paid or  expenses  incurred  in  settling  or
otherwise  disposing of a threatened  or pending  action or amounts  incurred in
defending  a pending  action  that is settled or  otherwise  disposed of without
court approval.

         California  law  requires   indemnification  when  the  individual  has
defended  successfully  the action on the merits (as  opposed to  Delaware  law,
which requires indemnification relating to a successful defense on the merits or
otherwise).
<PAGE>

         Delaware law generally permits  indemnification of expenses,  including
attorney's fees,  actually and reasonably  incurred in the defense or settlement
of a derivative or third-party  action,  provided there is a determination  by a
majority vote of a disinterested  quorum of the directors,  by independent legal
counsel or by a majority  vote of a quorum of the  stockholders  that the person
seeking  indemnification acted in good faith and in a manner reasonably believed
to be in or (in contrast to California law) not opposed to the best interests of
the corporation. Without court approval, however, no indemnification may be made
in respect of any derivative  action in which such person is adjudged liable for
negligence  or  misconduct  in  the  performance  of  his  or  her  duty  to the
corporation.   Delaware  law  requires  indemnification  of  expenses  when  the
individual being indemnified has successfully defended any action, claim, issue,
or matter therein, on the merits or otherwise.

         Expenses  incurred by an officer or director in defending an action may
be paid in advance,  under Delaware law and California  law, if such director or
officer undertakes to repay such amounts if it is ultimately  determined that he
or she is not entitled to indemnification.  In addition, the laws of both states
authorize a corporation's purchase of indemnity insurance for the benefit of its
officers,  directors,  employees and agents whether or not the corporation would
have the power to indemnify against the liability covered by the policy.

         California  law permits a California  corporation  to provide rights to
indemnification  beyond  those  provided  therein to the extent such  additional
indemnification  is authorized in the  corporation's  articles of incorporation.
Thus, if so authorized,  rights to  indemnification  may be provided pursuant to
agreements   or  bylaw   provisions   which  make   mandatory   the   permissive
indemnification  provided by California law. Under California law, there are two
limitations   on  such   additional   rights   to   indemnification:   (i)  such
indemnification is not permitted for acts,  omissions or transactions from which
a  director  of a  California  corporation  may  not  be  relieved  of  personal
liability, as described above; and (ii) such indemnification is not permitted in
circumstances  where  California  law expressly  prohibits  indemnification,  as
described above. The Company's Articles of Incorporation permit  indemnification
beyond that  expressly  mandated by the California  Corporations  Code and limit
director  monetary  liability  to the extent  permitted by  California  law. The
Company  has entered  into  indemnification  agreements  with its  officers  and
directors.

         Delaware   law  also   permits  a  Delaware   corporation   to  provide
indemnification in excess of that provided by statute. By contrast to California
law, Delaware law does not require authorizing  provisions in the certificate of
incorporation and does not contain express  prohibitions on  indemnification  in
certain circumstances; limitations on indemnification may be imposed by a court,
however, based on principles of public policy.

         A provision of Delaware law states that the indemnification provided by
statute  shall not be deemed  exclusive  of any other  rights  under any  bylaw,
agreement,  vote of stockholders or disinterested directors or otherwise.  Under
Delaware law,  therefore,  the  indemnification  agreements  entered into by the
Company with its officers and directors  may be assumed by Sierra  Delaware upon
completion  of the  Reincorporation.  If the  Reincorporation  is approved,  the
indemnification  agreements  will be amended to the extent  necessary to conform
the  agreements to Delaware law, and a vote in favor of the  Reincorporation  is
also  approval  of  such  amendments  to  the  indemnification   agreements.  In
particular,  the  indemnification  agreements  will be amended to include within
their purview future changes in Delaware law that expand the  permissible  scope
of indemnification of directors and officers of Delaware corporations.
<PAGE>

         Inspection of Shareholder  List. Both California and Delaware law allow
any shareholder to inspect the shareholder list for a purpose reasonably related
to  such  person's  interest  as a  shareholder.  California  law  provides,  in
addition,   for  an  absolute  right  to  inspect  and  copy  the  corporation's
shareholder   list  by  persons  holding  an  aggregate  of  5%  or  more  of  a
corporation's  voting shares, or shareholders holding an aggregate of 1% or more
of such shares who have filed a Schedule  14B with the  Securities  and Exchange
Commission in  connection  with a contested  election of  directors.  The latter
provision  has not been amended in response to the  elimination  of Schedule 14B
under the revised proxy rules.  Under  California law, such absolute  inspection
rights also apply to a  corporation  formed under the laws of any other state if
its principal  executive  offices are in California or if it  customarily  holds
meetings of its board in  California.  Delaware law also provides for inspection
rights as to a list of  stockholders  entitled to vote at a meeting within a ten
day period  preceding a  stockholders'  meeting  for any purpose  germane to the
meeting. However, Delaware law contains no provisions comparable to the absolute
right of inspection provided by California law to certain shareholders.

         Dividends and Repurchases of Shares.  California law dispenses with the
concepts  of par value of shares as well as  statutory  definitions  of capital,
surplus  and the like.  The  concepts  of par value,  capital  and  surplus  are
retained under Delaware law.

         Under  California  law,  a  corporation  may not make any  distribution
(including dividends,  whether in cash or other property, and repurchases of its
shares,  other than  repurchases of its shares issued under employee stock plans
contemplated by Section 408 of the California  Corporations  Code) unless either
(i) the  corporation's  retained  earnings  immediately  prior  to the  proposed
distribution  equal or exceed the amount of the  proposed  distribution  or (ii)
immediately after giving effect to such distribution,  the corporation's  assets
(exclusive  of  goodwill,  capitalized  research  and  development  expenses and
deferred  charges)  would be at  least  equal  to 125% of its  liabilities  (not
including deferred taxes,  deferred income and other deferred credits),  and the
corporation's  current assets would be at least equal to its current liabilities
(or 125% of its  current  liabilities  if the average  pre-tax and  pre-interest
expense  earnings for the  preceding two fiscal years were less than the average
interest  expense  for  such  years).  Such  tests  are  applied  to  California
corporations on a consolidated basis.

         Delaware law permits a corporation  to declare and pay dividends out of
surplus  or, if there is no  surplus,  out of net profits for the fiscal year in
which the dividend is declared  and/or for the preceding  fiscal year as long as
the amount of capital of the  corporation  following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding  stock of all classes having a preference upon the
distribution  of assets.  In addition,  Delaware law  generally  provides that a
corporation  may  redeem or  repurchase  its shares  only if the  capital of the
corporation is not impaired and such  redemption or repurchase  would not impair
the capital of the corporation.

         Shareholder  Voting. Both California and Delaware law generally require
that a majority of the  shareholders  of both acquiring and target  corporations
approve statutory  mergers.  Delaware law does not require a stockholder vote of
the surviving corporation in a merger (unless the corporation provides otherwise
in its certificate of  incorporation) if (a) the merger agreement does not amend
the existing  certificate of  incorporation,  (b) each share of the stock of the
surviving corporation  outstanding  immediately before the effective date of the
merger is an identical  outstanding or treasury share after the merger,  and (c)
either no shares of common  stock of the  surviving  corporation  and no shares,
securities  or  obligations  convertible  into  such  stock  are to be issued or
delivered  under the plan of merger,  or the authorized  unissued  shares or the
treasury  shares of common stock of the  surviving  corporation  to be issued or
delivered under the plan of merger plus those initially issuable upon conversion
of any other shares,  securities or obligations to be issued or delivered  under
such plan do not exceed 20% of the  shares of common  stock of such  constituent
corporation  outstanding  immediately prior to the effective date of the merger.
California  law  contains a similar  exception  to its voting  requirements  for
reorganizations   where  shareholders  or  the  corporation   itself,  or  both,
immediately  prior  to  the  reorganization   will  own  immediately  after  the
reorganization  equity  securities  constituting  more than  five-sixths  of the
voting power of the surviving or acquiring corporation or its parent entity.
<PAGE>

         Both California law and Delaware law also require that a sale of all or
substantially  all of the assets of a  corporation  be approved by a majority of
the outstanding voting shares of the corporation transferring such assets.

         With certain  exceptions,  California  law also  requires that mergers,
reorganizations, certain sales of assets and similar transactions be approved by
a majority vote of each class of shares outstanding.  In contrast,  Delaware law
generally  does  not  require  class  voting,  except  in  certain  transactions
involving  an amendment  to the  certificate  of  incorporation  that  adversely
affects a specific class of shares.  As a result,  shareholder  approval of such
transactions may be easier to obtain under Delaware law for companies which have
more than one class of shares outstanding.

         California law also requires that holders of nonredeemable common stock
receive  nonredeemable  common  stock in a merger  of the  corporation  with the
holder of more than 50% but less than 90% of such common stock or its  affiliate
unless all of the holders of such common stock consent to the transaction.  This
provision of California law may have the effect of making a "cash-out" merger by
a majority shareholder more difficult to accomplish.  Although Delaware law does
not parallel  California law in this respect,  under some circumstances  Section
203 does provide  similar  protection  against  coercive  two-tiered  bids for a
corporation in which the stockholders are not treated equally.  See "Significant
Differences Between the Corporation Laws of California and Delaware--Stockholder
Approval of Certain Business Combinations."

         California law provides that, except in certain  circumstances,  when a
tender offer or a proposal for a reorganization  or for a sale of assets is made
by an interested party (generally a controlling or managing person of the target
corporation),  an  affirmative  opinion  in writing  as to the  fairness  of the
consideration to be paid to the shareholders  must be delivered to shareholders.
This fairness opinion  requirement does not apply to a corporation that does not
have shares held of record by at least 100 persons, or to a transaction that has
been qualified under California state securities laws. Furthermore,  if a tender
of shares or vote is sought  pursuant to an  interested  party's  proposal and a
later  proposal is made by another  party at least ten days prior to the date of
acceptance of the interested party proposal,  the shareholders  must be informed
of the later  offer and be afforded a  reasonable  opportunity  to withdraw  any
vote, consent or proxy, or to withdraw any tendered shares.  Delaware law has no
comparable provision.

         Interested  Director  Transactions.  Under both California and Delaware
law,  certain  contracts or transactions in which one or more of a corporation's
directors  has an  interest  are not void or voidable  because of such  interest
provided that certain  conditions,  such as obtaining the required  approval and
fulfilling the  requirements  of good faith and full  disclosure,  are met. With
certain  exceptions,  the conditions  are similar under  California and Delaware
law. Under California and Delaware law, (a) either the shareholders or the board
of directors must approve any such contract or transaction after full disclosure
of the  material  facts,  and, in the case of board  approval,  the  contract or
transaction  must also be "just and  reasonable"  (in  California) or "fair" (in
Delaware) to the corporation,  or (b) the contract or transaction must have been
just and  reasonable or fair as to the  corporation at the time it was approved.
In the latter case,  California law explicitly places the burden of proof on the
interested  director.  Under California law, if shareholder  approval is sought,
the  interested  director is not  entitled  to vote his shares at a  shareholder
meeting with respect to any action  regarding such contract or  transaction.  If
<PAGE>
board  approval is sought,  the  contract or  transaction  must be approved by a
majority  vote of a quorum of the  directors,  without  counting the vote of any
interested  directors  (except  that  interested  directors  may be counted  for
purposes of  establishing  a quorum).  Under  Delaware law, if board approval is
sought,  the  contract  or  transaction  must be  approved  by a majority of the
disinterested  directors  (even if the  disinterested  directors are less than a
quorum).  Therefore,  certain  transactions  that the Board of  Directors of the
Company  might  not be able to  approve  because  of the  number  of  interested
directors,  could be approved by a majority of the  disinterested  directors  of
Sierra Delaware,  although less than a majority of a quorum.  The Company is not
aware of any plans to propose any transaction involving directors of the Company
that could not be approved  under  California  law but could be  approved  under
Delaware law.

         Shareholder   Derivative   Suits.   California   law  provides  that  a
shareholder  bringing a derivative  action on behalf of a  corporation  need not
have been a shareholder  at the time of the  transaction  in question,  provided
that  certain  tests are met.  Under  Delaware  law, a  stockholder  may bring a
derivative  action on behalf of the  corporation  only if the  stockholder was a
stockholder of the  corporation at the time of the transaction in question or if
his or her  stock  thereafter  devolved  upon  him or her by  operation  of law.
California  law  also  provides  that  the  corporation  or the  defendant  in a
derivative  suit may make a  motion  to the  court  for an order  requiring  the
plaintiff  shareholder  to furnish a  security  bond.  Delaware  does not have a
similar bonding requirement.

         Appraisal Rights. Under both California and Delaware law, a shareholder
of a corporation  participating  in certain major  corporate  transactions  may,
under varying  circumstances,  be entitled to appraisal rights pursuant to which
such  shareholder may receive cash in the amount of the fair market value of his
or her shares in lieu of the  consideration he or she would otherwise receive in
the  transaction.  Under  Delaware  law,  such fair market  value is  determined
exclusive of any element of value arising from the accomplishment or expectation
of the merger or consolidation,  and such appraisal rights are not available (a)
with respect to the sale, lease or exchange of all or  substantially  all of the
assets of a  corporation,  (b) with  respect to a merger or  consolidation  by a
corporation  the  shares of which are  either  listed on a  national  securities
exchange or are held of record by more than 2,000  holders if such  stockholders
receive  only  shares  of the  surviving  corporation  or  shares  of any  other
corporation that are either listed on a national  securities exchange or held of
record by more than 2,000  holders,  plus cash in lieu of  fractional  shares of
such corporations, or (c) to stockholders of a corporation surviving a merger if
no vote of the stockholders of the surviving  corporation is required to approve
the merger under certain provisions of Delaware law.

         The  limitations  on  the   availability  of  appraisal   rights  under
California law are different from those under  Delaware law.  Shareholders  of a
California corporation whose shares are listed on a national securities exchange
or on a list of over-the-counter  margin stocks issued by the Board of Governors
of the Federal Reserve System generally do not have such appraisal rights unless
the holders of at least 5% of the class of outstanding shares claim the right or
the  corporation  or any law  restricts  the transfer of such shares.  Appraisal
rights  are  also  unavailable  if  the  shareholders  of a  corporation  or the
corporation  itself, or both,  immediately prior to the reorganization  will own
immediately after the  reorganization  equity securities  constituting more than
five-sixths of the voting power of the surviving or acquiring corporation or its
parent  entity  (as  will be the  case  in the  Reincorporation).  Appraisal  or
dissenters' rights are, therefore,  not available to shareholders of the Company
with respect to the Reincorporation.  California law generally affords appraisal
rights in sale of asset reorganizations.

         Dissolution.  Under California law,  shareholders holding fifty percent
(50%)  or  more  of  the  total  voting  power  may  authorize  a  corporation's
dissolution,  with  or  without  the  approval  of  the  corporations  board  of
directors,  and this right may not be modified by the articles of incorporation.
Under  Delaware  law,  unless the board of  directors  approves  the proposal to
dissolve,  the dissolution must be approved by all the stockholders  entitled to
vote  thereon.  Only if the  dissolution  is initially  approved by the board of
directors may it be approved by a simple majority of the  outstanding  shares of
the corporation's stock entitled to vote. In the event of such a board-initiated
dissolution,  Delaware  law  allows a  Delaware  corporation  to  include in its
<PAGE>

certificate of  incorporation a supermajority  (greater than a simple  majority)
voting   requirement  in  connection  with   dissolutions.   Sierra   Delaware's
Certificate of Incorporation  contains no such supermajority voting requirement,
however,  and a majority of the outstanding shares entitled to vote, voting at a
meeting  at  which a quorum  is  present,  would  be  sufficient  to  approve  a
dissolution of Sierra Delaware that had previously been approved by its Board of
Directors.

Certain Federal Income Tax Considerations

         The   following  is  a  discussion  of  certain   federal   income  tax
considerations that may be relevant to holders of the Company's Common Stock who
receive Sierra  Delaware Common Stock in exchange for their Company Common Stock
as a result of the  Reincorporation.  The discussion does not address all of the
tax  consequences  of the  Reincorporation  that may be relevant  to  particular
Company  shareholders,   such  as  dealers  in  securities,   or  those  Company
shareholders  who acquired their shares upon the exercise of stock options,  nor
does it address the tax  consequences  to holders of options or other  rights to
acquire  Company  Common Stock.  Furthermore,  no foreign,  state,  or local tax
considerations  are addressed  herein. IN VIEW OF THE VARYING NATURE OF SUCH TAX
CONSEQUENCES, EACH SHAREHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR AS
TO THE SPECIFIC TAX CONSEQUENCES OF THE PROPOSED REINCORPORATION,  INCLUDING THE
APPLICABILITY OF FEDERAL, STATE, LOCAL OR FOREIGN TAX LAWS.

         Subject to the  limitations,  qualifications  and exceptions  described
herein, and assuming the  Reincorporation  qualifies as a reorganization  within
the  meaning of  Section  368(a) of the Code,  the  following  tax  consequences
generally should result:

                  (a) No gain or loss should be recognized by holders of Company
         Common Stock upon receipt of Sierra  Delaware  Common Stock pursuant to
         the Reincorporation;

                  (b) The  aggregate  tax basis of the  Sierra  Delaware  Common
         Stock  received by each  shareholder in the  Reincorporation  should be
         equal  to  the  aggregate  tax  basis  of  the  Company   Common  Stock
         surrendered in exchange therefor; and

                  (c) The holding  period of the Sierra  Delaware  Common  Stock
         received by each  shareholder  of the Company should include the period
         for which such shareholder held the Company Common Stock surrendered in
         exchange therefor,  provided that such Company Common Stock was held by
         the shareholder as a capital asset at the time of Reincorporation.

         The  Company  has not  requested  a ruling  from the  Internal  Revenue
Service (the "IRS") with respect to the federal income tax  consequences  of the
Proposed  Reincorporation under the Code. The Company will, however,  receive an
opinion from its legal counsel,  Wilson Sonsini Goodrich & Rosati,  Professional
Corporation,  substantially to the effect that the Proposed Reincorporation will
qualify as a  reorganization  within the  meaning of Section  368(a) of the Code
(the "Tax  Opinion").  The Tax Opinion will neither bind the IRS nor preclude it
from asserting a contrary position. In addition, the Tax Opinion will be subject
to certain  assumptions and  qualifications and will be based upon the truth and
accuracy  of  representations  made  by the  Company  and  Sierra  Delaware.  Of
particular  importance will be assumptions and  representations  relating to the
requirement (the "continuity of interest"  requirement) that the shareholders of
the Company  retain,  through  ownership of Sierra Delaware stock, a significant
equity interest in the Company's business after the Reincorporation.

         A  successful  IRS  challenge  to  the  reorganization  status  of  the
Reincorporation  (in  consequence  of a failure to satisfy  the  "continuity  of
interest"  requirement or otherwise)  would result in a shareholder  recognizing
gain or loss with respect to each share of the Company Common Stock exchanged in
the  Reincorporation  equal to the difference between the shareholder's basis in
such share and the fair market value, as of the time of the Reincorporation,  of
the Sierra Delaware Common Stock received in exchange therefor. In such event, a
shareholder's  aggregate  basis in the shares of Sierra  Delaware  Common  Stock
<PAGE>
received in the exchange  would equal their fair market value on such date,  and
the  shareholder's  holding  period for such shares would not include the period
during  which  the  shareholder  held  the  Company  Common  Stock.  Even if the
Reincorporation  qualifies as a  reorganization  under the Code,  a  shareholder
would  recognize  gain to the  extent  the  shareholder  received  (actually  or
constructively)  consideration  other  than  Sierra  Delaware  Common  Stock  in
exchange for the shareholder's Common Stock of the Company.

Description of Securities of Sierra Delaware

         The  authorized  capital  stock  of the  Sierra  Delaware  consists  of
50,000,000  shares  of Common  Stock,  no par  value,  and  5,000,000  shares of
undesignated  Preferred  Stock, no par value.  The following  summary of certain
provisions  of the  Common  Stock and  Preferred  Stock  does not  purport to be
complete and is subject to, and  qualified in its entirety by the  provisions of
Sierra  Delaware's  Certificate  of  Incorporation  and  by  the  provisions  of
applicable law.

         Common  Stock.  The Common Stock Shares of Sierra  Delaware have no par
value.  Subject to  preferences  that may be applicable  to any Preferred  Stock
which  may be issued  in the  future,  the  holders  of  Common  Stock of Sierra
Delaware are entitled to receive ratably such non-cumulative  dividends, if any,
as may be  declared  from  time to time by the Board of  Directors  out of funds
legally  available  therefor.  The  Common  Stock  of  Sierra  Delaware  has  no
preemptive  or  conversion  rights or other  subscription  rights.  There are no
redemption  or sinking  fund  provisions  applicable  to the Common  Stock.  The
holders of Common Stock of Sierra Delaware are entitled to one vote per share on
all  matters  to be  voted  upon  by the  stockholders.  Cumulative  voting  for
directors will apply unless the Company's  shareholders  approve Proposal No. 4.
In the event of liquidation,  dissolution or winding up of Sierra Delaware,  the
holders of Common Stock of Sierra  Delaware are entitled to share ratably in all
assets   remaining  after  payment  of   liabilities,   subject  to  liquidation
preferences,  if any, of Preferred Stock which may be issued in the future.  All
outstanding shares of Common Stock are fully paid and non-assessable.

         Preferred  Stock.  The Board of  Directors  of Sierra  Delaware has the
authority to issue up to 5,000,000  additional  shares of Preferred Stock in one
or more series,  to fix the rights,  preferences,  privileges  and  restrictions
granted to or imposed upon any wholly unissued series of Preferred Stock, and to
fix the number of shares  constituting  any series and the  designations of such
series,  without any further  vote or action by the  stockholders.  The Board of
Directors,  without Common Stock stockholder approval, can issue Preferred Stock
with voting and conversion  rights which could adversely affect the voting power
of the holders of Common  Stock.  The issuance of  Preferred  Stock may have the
effect of  delaying,  deferring  or  preventing  a change in  control  of Sierra
Delaware.

         Rights of Holders of Special Shares of PMC. The Special Shares,  no par
value,  of PMC are  redeemable  for Common Stock of Sierra  California.  Special
Shares do not have voting rights in Sierra California, but in all other respects
they  represent  the economic and  functional  equivalent of the Common Stock of
Sierra  California for which they can be redeemed.  Under  applicable  law, each
class of Special  Shares will have class voting rights in certain  circumstances
with respect to transactions that affect the rights of the class and for certain
extraordinary  corporate  transactions.  Upon the Effective  Date, all of Sierra
California's  obligations  towards holders of PMC Special Shares will be assumed
by Sierra Delaware.

                                 PROPOSAL NO. 3:
                                 CHANGE OF NAME

         The Company proposes to change its name to PMC-Sierra,  Inc. since this
name reflects the Company's  current  position in the  networking  market better
than its current name,  which is associated  with the Company's  business in the
custom,  graphics and modem chipset markets.  If the shareholders of the Company
approve the name change,  PMC will change its name to PMC-Sierra,  Inc. (Canada)
or a  similar  name.  The name  change is not  conditioned  on  approval  of the
Reincorporation.  If the Reincorporation  does not occur and the shareholders of
the Company  approve  Proposal No. 3, Sierra  California will change its name to
PMC-Sierra,  Inc. If the Reincorporation  does occur and the shareholders of the
Company  approve  Proposal  No.  3,  then  the name  change  will be part of the
Reincorporation.

Vote Required

         Approval of the name change will  require the  affirmative  vote of the
holders of a majority of the outstanding shares of the Company's Common Stock.

Recommendations

         The Company's  Board of Directors  recommends a vote "FOR" Proposal No.
3.  The  effect  of an  abstention  is the  same as that of a vote  against  the
Proposal.

                                 PROPOSAL NO. 4:
                        ELIMINATION OF CUMULATIVE VOTING

         The Company proposes that the Certificate of  Incorporation  and Bylaws
of Sierra Delaware will not provide for cumulative voting. The Company's current
Articles of Incorporation  and Bylaws permit cumulative  voting,  but cumulative
voting  has  not to date  been  exercised  by the  Company's  shareholders.  The
elimination  of cumulative  voting is not being  proposed in order to prevent an
unsolicited takeover attempt, nor is it in response to any present attempt known
to  the  Board  of  Directors  to  acquire   control  of  the  Company,   obtain
representation on the Board of Directors or take significant action that affects
the Company.

         Elimination of cumulative voting is proposed as part of and conditioned
upon the  Reincorporation.  If the  Reincorporation  does not occur,  cumulative
voting will remain in effect.  Elimination of cumulative  voting was unanimously
approved by the Company's  Board of  Directors.  The  elimination  of cumulative
voting may be considered to have an  antitakeover  effect in that it can make it
more  difficult  for  minority  shareholders  to gain a seat on the  Board.  See
Proposal No. 2 - "Antitakeover Implications" and "The Charters and Bylaws of the
Company and Sierra Delaware".  For a discussion of differences  between the laws
of  California  and  Delaware,  see  Proposal No. 2 -  "Significant  Differences
Between the Corporation Laws of California and Delaware".

Vote Required

         Approval of this  proposal  will  require the  affirmative  vote of the
holders of a majority of the outstanding shares of the Company's Common Stock.

Recommendations

         The Company's  Board of Directors  recommends a vote "FOR" Proposal No.
4.  The  effect  of an  abstention  is the  same as that of a vote  against  the
proposal.
<PAGE>

                                 PROPOSAL NO. 5:
      ELIMINATION OF THE ABILITY OF SHAREHOLDERS TO ACT BY WRITTEN CONSENT

         The Company proposes that the Certificate of  Incorporation  and Bylaws
of Sierra  Delaware will not provide for the ability of  shareholders  to act by
written  consent.  Articles  of  Incorporation  and Bylaws of Sierra  California
permit the shareholders to effect an action by written consent of holders of the
number of shares  that would be  necessary  to take the action at a  shareholder
meeting,  except  that  election  of  directors  requires  the  consent  of  all
shareholders,  and filling a vacancy on the board of directors  by  shareholders
requires the consent of the holders of a majority of the outstanding shares. The
Company's  shareholders  have not acted by written  consent  since the Company's
initial public  offering.  The  elimination of  shareholders'  action by written
consent  is not being  proposed  in order to  prevent  an  unsolicited  takeover
attempt,  nor is it in  response to any  present  attempt  known to the Board of
Directors to acquire control of the Company,  obtain representation on the Board
of Directors or take significant action that affects the Company.

         Elimination of the ability of shareholders to act by written consent is
proposed  as  part  of  and  conditioned  upon  the   Reincorporation.   If  the
Reincorporation  does not occur,  the existing ability to act by written consent
will remain in effect.  The elimination of the ability of shareholders to act by
written  consent may be  considered  to have an  antitakeover  effect in that it
requires disclosing the proposal to all the shareholders of the Company in order
to assemble a meeting to obtain shareholder approval,  and thus can make it more
difficult to obtain shareholder approval without incurring potential opposition.
The  Delaware  General  Corporation  Law allows  shareholders  to act by written
consent  unless  otherwise  provided in the  Certificate of  Incorporation.  See
Proposal No. 2 -"Antitakeover  Implications" and "The Charters and Bylaws of the
Company and Sierra Delaware".

Vote Required

         Approval of this  proposal  will  require the  affirmative  vote of the
holders of a majority of the outstanding shares of the Company's Common Stock.

Recommendations

         The Company's  Board of Directors  recommends a vote "FOR" Proposal No.
5.  The  effect  of an  abstention  is the  same as that of a vote  against  the
proposal.

                                 PROPOSAL NO. 6:
                          APPROVAL OF AMENDMENT TO THE
                            1994 INCENTIVE STOCK PLAN

         The 1994  Incentive  Stock  Plan (the "1994  Plan") was  adopted by the
Board of Directors in January 1994 and approved by the shareholders in May 1994.
Prior to February  1997,  3,600,000  shares of Common  Stock were  reserved  for
issuance under the 1994 Plan. In February 1997, the Board of Directors  approved
an  amendment  to the 1994 Plan to increase  the number of shares  reserved  for
issuance by 500,000  shares to a new total of 4,100,000  shares.  Proposal No. 6
seeks  shareholder  approval of the amendment  made by the Board of Directors in
February 1997.

          The essential features of the 1994 Plan are set forth below:

         General:  The 1994 Plan  provides  for the  granting  to  employees  of
"incentive  stock  options"  within the meaning of Section  422 of the  Internal
Revenue Code of 1986 (the "Code"), and for the granting of nonstatutory options,
stock  bonuses  and stock  purchase  rights  to  employees,  consultants,  sales
representatives  and  distributors.  As of March 30,  1997,  options to purchase
2,462,553  were  outstanding,  859,053  shares were  available for future grant,
options to purchase 278,394 shares had been exercised and 20,000 shares had been
issued as a stock bonus.  As of March 30, 1997,  approximately  234 persons were
eligible to  participate in the 1994 Plan and the closing price of the Company's
Common Stock as last reported on the Nasdaq National Market was $16.50.

         Administration and Eligibility: The 1994 Plan is currently administered
by the Board of Directors.  The Stock Option Committee  (comprised of Mr. Diller
and any other  director) has authority to grant options to purchase up to 10,000
shares for each  individual,  but has no authority  to grant  options to persons
subject to Section 16 of the Exchange  Act.  The  administrator  determines  the
terms of options granted, including the exercise price, number of shares subject
to the option and the  exercisability  thereof,  and the terms of stock purchase
rights and stock bonuses.
<PAGE>

         The 1994 Plan  provides  that no officer or employee  may be granted in
any one fiscal year stock  options or purchase  rights with respect to more than
800,000  shares of Common Stock.  There is also a limit on the aggregate  market
value of shares  subject to all incentive  stock options which may be granted to
an optionee  during any calendar  year.  See "Tax  Information  Regarding  Stock
Options" below.

         Consideration  to be Paid: The  consideration to be paid for shares may
consist of cash, check,  promissory note, shares of Common Stock of the Company,
a reduction in the amount of any indebtedness of the Company to the optionee, or
such other  consideration  as permitted  under  applicable  law. The Company may
issue stock  bonuses in exchange  for past or future  services as  permitted  by
applicable law.

         Additional  Terms  of  Options:  Options  are not  transferable  by the
optionee  other than by will or the laws of descent and  distribution,  and each
option is exercisable during the lifetime of the optionee only by such optionee.
The exercise price of all incentive  stock options must be at least equal to the
fair  market  value of the  shares  of Common  Stock on the date of  grant.  The
exercise  price of all  nonstatutory  stock  options must be at least 85% of the
fair market  value of the Common Stock on the date of grant.  Options  generally
have not been granted at exercise prices less than 100% of the fair market value
on the date of grant.  The term of each  option may not  exceed ten years.  With
respect to any participant who owns stock possessing more than 10% of the voting
rights of the Company's  outstanding  capital  stock,  the exercise price of any
incentive stock option granted must equal at least 110% of the fair market value
on the grant date and the maximum term of the option must not exceed five years.

         The  administrators  of the 1994 Plan  determine  when options  granted
thereunder  will  become  exercisable.  Options  granted  before  March 1,  1996
generally  vest at the rate of 1/48th of the shares subject to the option at the
end of each calendar month. Options granted after March 1, 1996 generally become
exercisable  as to 1/4 of total  shares  subject to the  option  after one year;
thereafter,  1/48 of the shares  subject  to the option  vest at the end of each
calendar month.

         If a  participant's  services to the Company  terminate  for any reason
other than death or disability,  the  participants  option may be exercised only
during a specified  period of time after  termination and only to the extent the
option was  exercisable on the date of termination.  If a  participant's  status
changes from that of an employee to a consultant, the participant's options will
automatically convert from incentive stock options to nonstatutory stock options
on the 91st day after such change of status.

         In  the  event  of a  merger  of  the  Company  with  or  into  another
corporation or a sale of substantially all of the Company's assets, the Board of
Directors must accelerate the  exercisability of all outstanding  options unless
the outstanding options are assumed or equivalent options are substituted by the
successor corporation.
<PAGE>

         Additional  Terms of Stock Bonuses and Stock  Purchase  Rights:  Shares
issued  pursuant to stock  bonuses and stock  purchase  rights can be subject to
repurchase  by the Company at the original  purchase  price of the shares or, in
the case of stock bonuses, at the fair market price of the shares on the date of
grant in the event that the person acquiring the shares ceases to be employed by
the Company or ceases to be a distributor for or  representative of the Company.
The repurchase option lapses at a rate determined by the administrator.

         Terms of Options to Non-Officer Directors:  Option grants to members of
the Board of  Directors  who are not  employees  or  consultants  of the Company
("non-officer  directors")  are  automatic and  non-discretionary.  Upon initial
election,  each non-officer  director of the Company  automatically  receives an
option to purchase  20,000  shares of Common  Stock.  On June 1 in each calendar
year, each continuing  non-officer director of the Company who first served as a
non-officer director prior to September 1, 1995 automatically receives an option
to purchase 5,000 shares of Common Stock, provided in each case that such person
has served in such capacity for the prior 12 months.  Each non-officer  director
of the Company who first served as a  non-officer  director  after  September 1,
1995, shall  automatically be granted an option to purchase 5,000 shares on each
anniversary date of each such person's election to the board, provided each such
person continues to serve as a non-officer director on such dates. Additionally,
in September  1996 the Board granted to each  non-officer  director an option to
purchase 5,000 shares.  Options granted before March 1, 1996 become  exercisable
at the rate of 1/48th of the  shares  subject  to the  option at the end of each
calendar month.  Options granted after March 1, 1996, become  exercisable at the
rate  of 1/4  of  the  total  shares  subject  to the  option  after  one  year;
thereafter,  1/48 of the shares  subject  to the option  vest at the end of each
calendar month.

         Amendments  to the Plan:  The Board of Directors may amend or terminate
the plan from time to time in such respect as the board may deem  advisable.  To
the extent  necessary and desirable to comply with Rule 16b-3 under the Exchange
Act (or any  other  applicable  law or  regulation),  the  Company  will  obtain
approval  of the  shareholders  of the  Company  to the extent and in the manner
required by such law or regulation.

         Tax Information Regarding Stock Options: Options granted under the 1994
Plan may be either  "incentive  stock options," as defined in Section 422 of the
Code, or nonstatutory options.

         An optionee who is granted an incentive stock option will not recognize
taxable  income  either at the time the option is granted or upon its  exercise,
although the exercise may subject the optionee to the  alternative  minimum tax.
Upon the sale or  exchange  of the shares more than two years after grant of the
option  and one year  after  exercising  the  option,  any gain or loss  will be
treated as long-term  capital  gain or loss.  If these  holding  periods are not
satisfied,  the optionee will recognize  ordinary  income at the time of sale or
exchange equal to the difference between the exercise price and the lower of (i)
the fair market  value of the shares at the date of the option  exercise or (ii)
the sale price of the shares.  A different  rule for measuring  ordinary  income
upon such a premature  disposition may apply if the optionee is also an officer,
director,  or 10% shareholder of the Company.  The Company will be entitled to a
deduction in the same amount as the ordinary income  recognized by the optionee.
Any gain or loss  recognized  on such a premature  disposition  of the shares in
excess of the  amount  treated  as  ordinary  income  will be  characterized  as
long-term or short-term capital gain or loss, depending on the holding period.

         All other options  which do not qualify as incentive  stock options are
referred to as nonstatutory  options. An optionee will not recognize any taxable
income  at the time he is  granted  a  nonstatutory  option.  However,  upon its
exercise,  the optionee will recognize taxable income generally  measured as the
excess of the then fair market value of the shares  purchased  over the purchase
price. Any taxable income recognized in connection with an option exercise by an
optionee  who is  also  an  employee  of the  Company  will  be  subject  to tax
withholding  by the  Company.  Upon resale of such shares by the  optionee,  any
difference  between the sales price and the optionee's tax basis (purchase price
plus the  income  recognized  on  exercise),  will be treated  as  long-term  or
short-term capital gain or loss, depending on the holding period.
<PAGE>

         The Company  will be entitled to a tax  deduction in the same amount as
the ordinary  income  recognized by the Optionee with respect to shares acquired
upon exercise of a nonstatutory option.

         The  foregoing  is only a  summary  of the  effect  of  federal  income
taxation  upon the  optionee  and the  Company  with  respect  to the  grant and
exercise of options  under the 1994 Plan,  does not purport to be complete,  and
does not discuss the tax  consequences of the optionee's death or the income tax
laws of any  municipality,  state or foreign  country in which an  optionee  may
reside.

         Tax Information  Regarding  Stock Purchase and Stock Bonus Rights:  The
shares of Common  Stock  acquired  upon  exercise of a stock  purchase  right or
pursuant to a stock bonus will be deemed  "property  subject to substantial risk
of forfeiture"  within the meaning of Section 83 of the Internal Revenue Code by
reason of the repurchase option in favor of the Company described above.  Unless
an election is filed with the Internal  Revenue  Service  under Section 83(b) of
the Code  within 30 days after the date of purchase  or bonus,  the  participant
will not be taxed at the time of purchase or bonus on any difference between the
fair market  value of the shares at the time of purchase or bonus and the amount
(if any) paid for the shares, nor will the participant's  long-term capital gain
holding  period begin to run at the time of purchase or bonus.  Rather,  at such
time or times as the repurchase  option expires,  the participant will recognize
ordinary income in an amount equal to the difference between the amount (if any)
paid for the  shares  and the fair  market  value of the  shares at such time or
times,  whether  or not the  shares  are sold at such  tune,  and the  long-term
capital  gain  holding  period  will  begin to run at such time or times.  If an
election is timely made under Section  83(b),  the  participant  will  recognize
ordinary income at the time of purchase or bonus in the amount of any difference
between the fair market  value of the stock at such time and the amount (if any)
paid for the  shares.  The income  recognized  by a  participant  who is also an
employee will be treated as wages and will be subject to tax  withholding by the
Company.  The Company  will be entitled to a tax  deduction in the amount and at
the time that the participant  recognizes ordinary income with respect to shares
acquired upon exercise of a stock purchase right or pursuant to a stock bonus.

         Participation  in the  Option  Plan:  The  grant of  options  and stock
purchase  rights  under the 1994 Plan to  executive  officers  is subject to the
discretion  of the Board or the Plan  Committee.  Options to purchase a total of
315,000 shares were granted  during fiscal 1996 to executive  officers under the
1994 Plan.  There has been no  determination  by the Board or the Plan Committee
with respect to future awards under the 1994 Plan.

         The grant of options  under the 1994 Plan to  non-officer  directors is
described under "Terms of Options to Non-Officer Directors." Options to purchase
a total  of  35,000  shares  were  granted  during  fiscal  1996 to  non-officer
directors  under the 1994  Plan.  Assuming  that each of the  Company's  current
non-officer  directors  remains a  director  through  June 5,  1997,  options to
purchase 35,000 shares will be granted to non-officer  directors in fiscal 1997.
Each of these  options will be  exercisable  at a price equal to the fair market
value of the Company's  Common Stock on the date of grant. It is not possible at
this time to determine the value of these option grants.

         The following table sets forth information  regarding grants made under
the 1994 Plan for the last  fiscal  year  ended  December  29,  1996 to (i) each
executive  officer  named in the Summary  Compensation  Table,  (ii) all current
executive  officers as a group,  (iii) all non-officer  directors as a group and
(iv) all  employees  as a group.  Mr.  Beaumont  received  an option to purchase
20,000 shares at an exercise  price of $15.8125 per share in April 1997 upon his
election to the Board.  Future option grants to the individuals listed below are
not  presently   determinable,   except  for  the  automatic  option  grants  to

Recommendations

         The Company's Board of Directors recommends a vote FOR Proposal No. 6.


                                 PROPOSAL NO. 7:
       APPROVAL OF THE 1996 PMC-SIERRA, INC. (PORTLAND) STOCK OPTION PLAN

         The  Company has agreed to issue up to 450,000  shares of Common  Stock
upon exercise of options held by employees of PMC-Sierra,  Inc. (Portland) ("PMC
Portland")  under the PMC Portland  Stock  Option Plan  ("Portland  Plan").  The
Portland  Plan is being  submitted  to the  shareholders  for  approval  so that
options granted under the Portland Plan qualify as incentive stock options.  The
principal features of the Portland Plan are outlined below:

         General:  The Portland  Plan  provides PMC Portland  employees  with an
opportunity to purchase Common Stock of the Company.

         The Portland Plan  provides for the grant to PMC Portland  employees of
"incentive  stock  options"  within the meaning of Section  422 of the  Internal
Revenue Code of 1986 (the "Code"),  and for the grant of nonstatutory options to
PMC  Portland  employees  and  consultants.  As of March 29,  1997,  options  to
purchase  385,938  shares were  outstanding,  40,058  shares were  available for
future grant, and 24,004 had been exercised. As of March 30, 1997, approximately
16 persons were  eligible to  participate  in the Portland  Plan and the closing
price of the  Company's  Common  Stock as last  reported on the Nasdaq  National
Market was $16.50.
<PAGE>

         Administration   and  Eligibility:   The  Portland  Plan  is  currently
administered  by  the  PMC  Portland  Board  of  Directors.   The  administrator
determines the terms of options granted, including the exercise price, number of
shares subject to the option and the exercisability thereof.

         The Portland  Plan  provides that no officer or employee may be granted
in any one fiscal  year stock  options or purchase  rights with  respect to more
than  450,000  shares of Common  Stock.  There is also a limit on the  aggregate
market  value of shares  subject to all  incentive  stock  options  which may be
granted to an optionee during any calendar year. See "Tax Information  Regarding
Stock Options" below.

         Consideration  to be Paid: The  consideration to be paid for shares may
consist of cash, check,  promissory note, shares of Common Stock of the Company,
a reduction in the amount of any indebtedness of the Company to the optionee, or
other  consideration as permitted under state and corporate  securities laws and
the Internal Revenue Code.

         Additional  Terms  of  Options:  Options  are not  transferable  by the
optionee  other than by will or the laws of descent and  distribution,  and each
option is exercisable during the lifetime of the optionee only by such optionee.
The exercise price of all incentive  stock options must be at least equal to the
fair market  value of the shares of Common Stock of Sierra on the date of grant.
The exercise price of all nonstatutory stock options must be at least 85% of the
fair  market  value of  Sierra's  Common  Stock on the  date of  grant.  Options
generally  have not been  granted at exercise  prices less than 100% of the fair
market  value on the date of grant.  The term of each  option may not exceed ten
years.  With respect to any participant who owns stock  possessing more than 10%
of the voting rights of the Sierra outstanding capital stock, the exercise price
of any  incentive  stock  option  granted  must  equal at least 110% of the fair
market  value on the grant  date and the  maximum  term of the  option  must not
exceed five years.

         The  administrator of the Portland Plan determines when options granted
thereunder will become  exercisable.  Options generally become exercisable as to
1/4 of the total shares subject to the option after one year;  thereafter,  1/48
of the shares subject to the option vest at the end of each calendar month.

         If a  participant's  services to the Company  terminate  for any reason
other than death or disability,  the participant's  option may be exercised only
during a specified  period of time after  termination and only to the extent the
option was  exercisable on the date of  termination.  Upon such  termination the
participant's  option will  continue to vest  according to the vesting  schedule
unless the  termination is by the Company for cause,  as defined in the Portland
Plan.  If  a  participant's  status  changes  from  that  of  an  employee  to a
consultant, the participant's options automatically convert from incentive stock
options to  nonstatutory  stock  options  on the 91st day after  such  change of
status.

         In  the  event  of a  merger  of  the  Company  with  or  into  another
corporation or a sale of substantially all of the Company's assets, the Board of
Directors must accelerate the  exercisability of all outstanding  options unless
the outstanding options are assumed or equivalent options are substituted by the
successor corporation.

         Amendments  to the Plan:  The Board of Directors may amend or terminate
the plan from time to time in such respect as the board may deem  advisable.  To
the extent  necessary and desirable to comply with Rule 16b-3 under the Exchange
Act (or any  other  applicable  law or  regulation),  the  Company  will  obtain
approval  of the  shareholders  of the  Company  to the extent and in the manner
required by such law or regulation.
<PAGE>

         Tax  Information  Regarding  Stock Options:  Options  granted under the
Portland Plan may be either "incentive stock options," as defined in Section 422
of the Code, or nonstatutory options.

         An optionee who is granted an incentive stock option will not recognize
taxable  income  either at the time the option is granted or upon its  exercise,
although the exercise may subject the optionee to the  alternative  minimum tax.
Upon the sale or  exchange  of the shares more than two years after grant of the
option  and one year  after  exercising  the  option,  any gain or loss  will be
treated as long-term  capital  gain or loss.  If these  holding  periods are not
satisfied,  the optionee will recognize  ordinary  income at the time of sale or
exchange equal to the difference between the exercise price and the lower of (i)
the fair market  value of the shares at the date of the option  exercise or (ii)
the sale price of the shares.  A different  rule for measuring  ordinary  income
upon such a premature  disposition may apply if the optionee is also an officer,
director,  or 10% shareholder of the Company.  The Company will be entitled to a
deduction in the same amount as the ordinary income  recognized by the optionee.
Any gain or loss  recognized  on such a premature  disposition  of the shares in
excess of the  amount  treated  as  ordinary  income  will be  characterized  as
long-term or short-term capital gain or loss, depending on the holding period.

         All other options  which do not qualify as incentive  stock options are
referred to as nonstatutory  options. An optionee will not recognize any taxable
income  at the time he is  granted  a  nonstatutory  option.  However,  upon its
exercise,  the optionee will recognize taxable income generally  measured as the
excess of the then fair market value of the shares  purchased  over the purchase
price. Any taxable income recognized in connection with an option exercise by an
optionee  who is  also  an  employee  of the  Company  will  be  subject  to tax
withholding  by the  Company.  Upon resale of such shares by the  optionee,  any
difference  between the sales price and the optionee's tax basis (purchase price
plus the  income  recognized  on  exercise),  will be treated  as  long-term  or
short-term capital gain or loss, depending on the holding period.

         The Company  will be entitled to a tax  deduction in the same amount as
the ordinary  income  recognized by the Optionee with respect to shares acquired
upon exercise of a nonstatutory option.

         The  foregoing  is only a  summary  of the  effect  of  federal  income
taxation  upon the  optionee  and the  Company  with  respect  to the  grant and
exercise of options  under the Portland  Plan,  does not purport to be complete,
and does not discuss the tax  consequences of the optionee's death or the income
tax laws of any municipality,  state or foreign country in which an optionee may
reside.

         Participation  in the  Portland  Plan:  The grant of options  under the
Portland Plan to executive  officers,  is subject to the discretion of the Board
of PMC  Portland.  No options  were  granted  during  fiscal  1996 to  executive
officers or non-officer  directors of the Company under the Portland Plan. There
has been no  determination  by the Board of PMC Portland  with respect to future
awards under the Portland Plan.

Vote Required

         The  affirmative  vote of a majority of the Votes Cast will be required
to approve the Portland Plan.

Recommendations

         The Company's Board of Directors recommends a vote FOR Proposal No. 7.

                                 PROPOSAL NO. 8:
               CONFIRMATION OF APPOINTMENT OF INDEPENDENT AUDITORS

         On April 14, 1997, following a recommendation by the audit committee of
the Company's  Board of Directors,  the  Company's  Board of Directors  selected
Deloitte & Touche LLP as the Company's  independent auditors for the 1997 fiscal
year and  dismissed  the  Company's  independent  auditors for 1996 fiscal year,
Ernst & Young LLP.  In  connection  with the audits of the  Company's  financial
statements  for the two most recent fiscal years and in the  subsequent  interim
period,  there were no disagreements with Ernst & Young LLP regarding accounting
principles or practices,  financial statement disclosure,  or auditing scope and
procedures  which,  if not  resolved to the  satisfaction  of Ernst & Young LLP,
would have  caused  Ernst & Young LLP to make  reference  to the matter in their
report.  Ernst & Young LLP's reports for either of the past two completed fiscal
years did not contain an adverse opinion or a disclaimer of opinion, and was not
qualified as to  uncertainty,  audit scope or  accounting  principles.  Prior to
selecting  Deloitte & Touche LLP, the Company had not consulted  with Deloitte &
Touche LLP regarding the application of accounting principles, the type of audit
opinion that might be rendered on the  Company's  financial  statements,  or any
event that was either a reportable event or the subject of a disagreement.

         The  Company's  Board of  Directors  recommends  that the  shareholders
ratify such  selection.  In the event of a negative vote, the Board of Directors
will  reconsider  its  selection.  Representatives  of Deloitte & Touche LLP are
expected to be present at the meeting with the  opportunity  to make a statement
if they  desire  to do so,  and are  expected  to be  available  to  respond  to
appropriate questions.

Vote Required

         The  affirmative  vote of a majority of the Votes Cast will be required
to confirm the  appointment of Deloitte & Touche LLP as independent  auditors of
the Company for the 1997 fiscal year.

Recommendation

         The Company's Board of Directors recommends a vote FOR Proposal No. 8.

Compensation Committee Report on Executive Compensation

   Compensation Philosophy.

         Under the  supervision  of the  Compensation  Committee of the Board of
Directors,  the Corporation has developed and implemented compensation policies,
plans and programs which seek to enhance the  profitability of the Company,  and
thus  shareholder  value,  by aligning  closely the  financial  interests of the
Company's  senior  managers with those of its  shareholders.  In  furtherance of
these goals,  annual base salaries are generally set below competitive levels to
emphasize  annual  and  longer-term  incentive  compensation.  This is  meant to
attract,  motivate  and retain  corporate  officers  and other key  employees to
perform  to the  full  extent  of  their  abilities.  Both  types  of  incentive
compensation are variable and closely tied to corporate  performance in a manner
that encourages continuing focus on profitability and shareholder value.

         Compensation for the Company's  executive  officers  consists of a base
salary  and  annual  and  longer-term  incentive  compensation.   The  Committee
considers  the total  compensation  (earned or  potentially  available)  of each
executive officer in establishing each element of compensation.

   Cash-Based Compensation.

         Each fiscal year the Committee reviews with the Chief Executive Officer
and approves, with appropriate modifications, an annual base salary plan for the
Company's senior  executives.  This base salary plan is based on industry,  peer
group,  and  national  surveys  and  performance  judgements  as to the past and
expected future  contributions  of the individual  senior  executives.  The base
salaries  are fixed at a level  below  the  competitive  amounts  paid to senior
managers with  comparable  qualifications,  experience and  responsibilities  at
other similarly sized high-technology companies. The Committee reviews and fixes
the base  salary of the Chief  Executive  Officer  based on similar  competitive
compensation data and the Committee's assessment of his past performance and its
expectation as to his future contributions in leading the Company.

         Each  executive  officer,  including the Chief  Executive  Officer,  is
eligible  to  receive  a  quarterly  cash  bonus  equal to a  percentage  of the
Company's operating group's pre-tax profits for the quarter.  The percentages of
profits  for  each  participant  are  determined  annually  by the  Compensation
Committee  based upon  performance  judgments as to the past and expected future
contributions of the individual senior executives.
<PAGE>

   Stock Options.

         During each fiscal year, the Committee  considers the  desirability  of
granting to executive officers awards under the Company's  Incentive Stock Plan,
which provides the flexibility to grant  longer-term  incentives in a variety of
forms,  including  stock options and restricted  stock.  In fixing the grants of
stock options to executive  officers (other than the Chief  Executive  Officer),
the  Committee  reviewed  with  the  Chief  Executive  Officer  the  recommended
individual  award,  taking into account scope of  accountability,  strategic and
operational goals, and anticipated performance requirements and contributions of
the senior  management group. The award to the Chief Executive Officer was fixed
separately  and was  based,  among  other  things,  on a review  of  competitive
compensation  data from several  surveys,  data from  selected  peer  companies,
information  regarding long-term  compensation awards as well as the Committee's
perception  of  past  and  expected  future   contributions   to  the  Company's
achievement of its long-term  performance  goals.  In addition,  when hiring new
executive  officers,  the  Committee  may  recommended  a grant of options  upon
acceptance  of  employment.  These grants are made in order to retain  qualified
personnel  and take into  account the  compensation  policies  of the  Company's
competitors and the unique qualifications of the new executives.

                                                    Respectfully submitted by:
                                                    Alexandre Balkanski
                                                    Michael L. Dionne

Compensation Committee Interlocks and Insider Participation

         During fiscal 1996,  the Company sold  $18,936,000 of products to Apple
Computer,  Inc.,  with  which  Mr.  Dionne,  a  director  of  the  Company,  was
affiliated.

and returned to the status of authorized but unissued shares.

         3.4. Exchange of Certificates. After the Effective Date, each holder of
an outstanding certificate representing shares of Sierra-California Common Stock
may be asked to surrender the same for  cancellation to Boston  EquiServe,  L.P.
(the  "Exchange  Agent"),  and each such holder  shall be entitled to receive in
exchange  therefor a  certificate  or  certificates  representing  the number of
shares of the Surviving  Corporation's  Common  Stock,  as the case may be, into
which  the  surrendered  shares  were  converted  as herein  provided.  Until so
surrendered,  each outstanding  certificate  theretofore  representing shares of
Sierra-California Common Stock shall be deemed for all purposes to represent the
number of shares of the Surviving Corporation's Common Stock, respectively, into
which such shares of  Sierra-California  Common Stock,  as the case may be, were
converted in the Merger.

         The  registered  owner  on the  books  and  records  of  the  Surviving
Corporation or the Exchange  Agent of any such  outstanding  certificate  shall,
until such certificate shall have been surrendered for transfer or conversion or
otherwise accounted for to the Surviving Corporation or the Exchange Agent, have
and be entitled to exercise  any voting and other  rights with respect to and to
receive dividends and other distributions upon the shares of Common Stock of the
Surviving  Corporation  represented by such outstanding  certificate as provided
above.

         Each certificate representing Common Stock of the Surviving Corporation
so issued in the Merger shall bear the same legends, if any, with respect to the
restrictions on  transferability  as the  certificates of  Sierra-California  so
converted and given in exchange  therefore,  unless otherwise  determined by the
Board of Directors of the Surviving  Corporation in compliance  with  applicable
laws.

         If any certificate for shares of the Surviving  Corporation's  stock is
to be issued in a name other than that in which the  certificate  surrendered in
exchange  therefor is  registered,  it shall be a condition of issuance  thereof
that the certificate so surrendered  shall be properly endorsed and otherwise in
proper form for transfer, that such transfer otherwise be proper and comply with
applicable  securities laws and that the person  requesting such transfer pay to
the Exchange  Agent any transfer or other taxes payable by reason of issuance of
such new  certificate in a name other than that of the registered  holder of the
certificate  surrendered  or  establish  to the  satisfaction  of the  Surviving
Corporation that such tax has been paid or is not payable.

determined, and if so, on what terms;

                          (c)       the  right  or  obligation,  if any,  of the
Corporation  to redeem  shares of the  particular  class or series of  Preferred
Stock and, if redeemable, the price, terms and manner of such redemption;

                          (d)       the   special    and   relative  rights  and
preferences,  if any,  and the amount or amounts per share,  which the shares of

voluntary  or  involuntary  liquidation,   dissolution  or  winding  up  of  the
Corporation;

                          (e)       the terms and conditions, if any, upon which

adjustment, if any;

to  retire,  redeem or  purchase  shares of such class or series  pursuant  to a
sinking  fund or fund of a  similar  nature  or  otherwise,  and the  terms  and
conditions of such obligation;

                          (g)       voting rights,  if any,  on  the issuance of
additional  shares of such class or series or any  shares of any other  class or
series of Preferred Stock;

                          (h)       limitations,  if any,   on  the  issuance of
additional  shares of such class or series or any  shares of any other  class or
series of Preferred Stock; and

                          (i)       such      other     preferences,     powers,
qualifications,  special or relative rights and privileges  thereof as the Board
of Directors of the  Corporation,  acting in accordance with this Certificate of
Incorporation,  may deem  advisable  and are not  inconsistent  with law and the
provisions of this Restated Certificate of Incorporation.

                                   ARTICLE I.

 2.1.     PLACE OF MEETINGS
          -----------------
     Meetings of  stockholders  shall be held at any place within or outside the

executive office of the Corporation.

 2.2.     ANNUAL MEETING
          --------------
     The annual meeting of stockholders shall be held each year on a date and at
a time designated by the Board of Directors. In the absence of such designation,

business may be transacted.
<PAGE>

 2.3.     SPECIAL MEETING

less than ten percent (10%) of the votes at that meeting.

     If a special  meeting  is called by any  person or  persons  other than the
Board of  Directors  or the  President  or the  Chairman of the Board,  then the
request shall be in writing, specifying the time of such meeting and the general

notice to be promptly given to the stockholders  entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of these bylaws, that a meeting will
be held at the time requested by the person or persons  calling the meeting,  so
long as that time is not less than  thirty-five  (35) nor more than  sixty  (60)
days after the receipt of the request.  If the notice is not given within twenty
(20) days after  receipt of the request,  then the person or persons  requesting

          --------------------------------
     All notices of meetings of stockholders shall be sent or otherwise given in

meeting,  those matters which the Board of Directors,  at the time of giving the
notice, intends to present for action by the stockholders (but any proper matter
may be presented at the meeting for such  action).  The notice of any meeting at
which  directors  are to be elected  shall  include  the name of any  nominee or
nominees  who,  at the time of the  notice,  the Board  intends to  present  for
election.

 2.5.     NOTIFICATIONS OF NOMINATIONS AND PROPOSED BUSINESS.
          ---------------------------------------------------
     Subject to the  rights of holders of any class or series of stock  having a
preference over the Common Stock as to dividends or upon liquidation,

                    (a) nominations for the election of directors, and

                    (b) business  proposed  to be brought before any stockholder
                        meeting

may be made by the Board of Directors or proxy committee  appointed by the Board
of Directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business  proposed is otherwise  proper business
before such  meeting.  However,  any such  stockholder  may nominate one or more
persons for election as directors at a meeting or propose business to be brought
<PAGE>
before a meeting,  or both, only if such  stockholder has given timely notice in
proper  written form of his intent to make such  nomination or nominations or to
propose such business. To be timely, such stockholder's notice must be delivered
to or mailed and  received by the  Secretary  of the  Corporation  not less than
thirty-five  (35)  days nor more than  sixty  (60)  days  prior to the  meeting;
provided,  however, that in the event that less than forty-five (45) days notice
or  prior  public  disclosure  of the  date of the  meeting  is given or made to
stockholders,  notice by the  stockholder  to be timely must be so received  not
later than the close of  business  on the tenth day  following  the day on which
such notice of the date of the meeting was mailed or such public  disclosure was
made. To be in proper form, a  stockholder's  notice to the Secretary  shall set
forth:

                    (i) the name  and address of the  stockholder who intends to
                    make the  nominations  or propose the  business  and, as the
                    case may be, of the person or persons to be  nominated or of
                    the business to be proposed;

                    (ii) a  representation  that the  stockholder is a holder of
                    record of stock of the Corporation  entitled to vote at such
                    meeting and, if  applicable,  intends to appear in person or
                    by proxy at the  meeting to  nominate  the person or persons
                    specified in the notice;

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

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

                    (v) if  applicable,  the consent of each nominee to serve as
                    director of the Corporation if so elected.

     The Chairman of the meeting shall refuse to  acknowledge  the nomination of
any person or the  proposal  of any  business  not made in  compliance  with the
foregoing procedure.

 2.6.     MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
          --------------------------------------------
 Written notice of any meeting of stockholders  shall be given either personally
or by first-class mail or by telegraphic or other written communication. Notices
not personally delivered shall be sent charges prepaid and shall be addressed to
the stockholder at the address of that stockholder appearing on the books of the
Corporation or given by the  stockholder to the  Corporation  for the purpose of
notice.  Notice  shall be deemed to have been  given at the time when  delivered
personally  or  deposited  in the mail or sent by  telegram  or  other  means of
written communication.
<PAGE>

     An  affidavit  of the  mailing  or other  means of giving any notice of any
stockholders'  meeting,  executed by the Secretary,  assistant  secretary or any
transfer  agent of the  Corporation  giving  the  notice,  shall be prima  facie
evidence of the giving of such notice.

 2.7.     QUORUM
          ------
     The  holders  of a  majority  in  voting  power  of the  stock  issued  and
outstanding  and entitled to vote thereat,  present in person or  represented by
proxy,  shall  constitute a quorum at all meetings of the  stockholders  for the
transaction  of  business  except as  otherwise  provided  by  statute or by the
Certificate  of  Incorporation.  If,  however,  such  quorum is not  present  or
represented at any meeting of the stockholders,  then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented  by proxy,  shall have power to adjourn the meeting in accordance
with Section 2.8 of these bylaws.

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

     If a quorum be initially present, the stockholders may continue to transact
business   until   adjournment,   notwithstanding   the   withdrawal  of  enough
stockholders  to leave less than a quorum,  if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

 2.8.     ADJOURNED MEETING; NOTICE
          -------------------------
     When a meeting is adjourned to another time and place,  unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place  thereof  are  announced  at the meeting at which the  adjournment  is
taken.  At the adjourned  meeting the Corporation may transact any business that
might have been  transacted at the original  meeting.  If the adjournment is for
more than thirty  (30) days,  or if after the  adjournment  a new record date is
fixed for the  adjourned  meeting,  a notice of the  adjourned  meeting shall be
given to each stockholder of record entitled to vote at the meeting.

 2.9.     VOTING
          ------
     The stockholders  entitled to vote at any meeting of stockholders  shall be
determined  in accordance  with the  provisions of Section 2.11 of these bylaws,

     Each  stockholder  shall be  entitled to one vote for each share of capital

cumulate  their votes in the election of directors or with respect to any matter
submitted to a vote of the stockholders.

 2.10.    WAIVER OF NOTICE
          ----------------
     Whenever  notice is required to be given under any provision of the General
Corporation Law of Delaware or the Certificate of Incorporation or these bylaws,
a written  waiver  thereof,  signed by the person  entitled  to notice,  whether
before or after the time stated therein,  shall be deemed  equivalent to notice.
Attendance of a person at a meeting shall  constitute a waiver of notice of such
meeting,  except when the person  attends a meeting  for the express  purpose of
objecting,  at the beginning of the meeting,  to the transaction of any business
because the meeting is not lawfully called or convened.  Neither the business to
be  transacted  at, nor the purpose  of, any  regular or special  meeting of the
stockholders  need be  specified  in any  written  waiver  of  notice  unless so
required by the Certificate of Incorporation or these bylaws.

 2.11.    RECORD DATE FOR STOCKHOLDER NOTICE; VOTING
          ------------------------------------------
     For  purposes of  determining  the  stockholders  entitled to notice of any
meeting or to vote thereat, the Board of Directors may fix, in advance, a record
date,  which  shall not precede  the date upon which the  resolution  fixing the
record  date is adopted by the Board of  Directors  and which  shall not be more
than  sixty  (60) days nor less than ten (10) days  before  the date of any such
meeting,  and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote,  notwithstanding  any  transfer of any shares on
the books of the Corporation after the record date.

     If the Board of Directors  does not so fix a record  date,  the record date
for  determining  stockholders  entitled to notice of or to vote at a meeting of
stockholders  shall  be at the  close  of  business  on the  business  day  next
preceding  the day on which  notice is given,  or, if notice is  waived,  at the
close of  business  on the  business  day next  preceding  the day on which  the
meeting is held.

     A determination  of stockholders of record entitled to notice of or to vote
at a meeting of  stockholders  shall  apply to any  adjournment  of the  meeting
unless the Board of Directors fixes a new record date for the adjourned meeting,
but the  Board of  Directors  shall  fix a new  record  date if the  meeting  is
adjourned  for more than  thirty  (30)  days from the date set for the  original
meeting.

     The record date for any other  purpose  shall be as provided in Section 8.1
of these bylaws.

 2.12.    PROXIES
          -------
     Every person entitled to vote for directors,  or on any other matter, shall
have the right to do so either in person or by one or more agents  authorized by
a  written  proxy  signed by the  person  and filed  with the  Secretary  of the
Corporation,  but no such proxy  shall be voted or acted  upon  after  three (3)
years from its date unless the proxy provides for a longer period. A proxy shall
be deemed signed if the  stockholder's  name is placed on the proxy  (whether by
manual  signature,  typewriting,  telegraphic  transmission,   telefacsimile  or
otherwise)  by  the  stockholder  or  the  stockholder's  attorney-in-fact.  The
revocability of a proxy that states on its face that it is irrevocable  shall be
governed by the provisions of Section 212(e) of the General  Corporation  Law of
Delaware.

 2.13.    ORGANIZATION

     The  President,  or in the absence of the  President,  the  Chairman of the
Board, or, in the absence of the President and the Chairman of the Board, one of
the Corporation's vice presidents, shall call the meeting of the stockholders to
order,  and  shall  act as  chairman  of the  meeting.  In  the  absence  of the
President,  the  Chairman  of the  Board,  and all of the vice  presidents,  the

complete list of the stockholders  entitled to vote at the meeting,  arranged in
alphabetical  order,  and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the  examination  of any  stockholder,  for any purpose  germane to the meeting,

                                  ARTICLE III.

                                    DIRECTORS
                                    ---------

          ------
     Subject to the  provisions of the General  Corporation  Law of Delaware and
any limitations in the Certificate of Incorporation and these bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the  Corporation  shall be managed and all corporate
powers shall be exercised by or under the direction of the Board of directors.
<PAGE>

 3.2.     NUMBER OF DIRECTORS
          -------------------
     The  Board of  Directors  shall be six until  changed,  within  the  limits
specified  above by by an amendment to this bylaw,  duly adopted by the Board of
Directors  or by  the  stockholders,  or by a  duly  adopted  amendment  to  the
Certificate of Incorporation.

     No reduction of the authorized number of directors shall have the effect of
removing any director before that director's term of office expires.

 3.3.     ELECTION AND TERM OF OFFICE OF DIRECTORS
          ----------------------------------------
     Except as  provided  in Section  3.4 of these  bylaws,  directors  shall be
elected at each annual  meeting of  stockholders  to hold office  until the next
annual meeting. Each director, including a director elected or appointed to fill
a vacancy,  shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.

 3.4.     RESIGNATION AND VACANCIES
          -------------------------
     Any director may resign  effective on giving written notice to the Chairman
of the Board, the President, the Secretary or the Board of Directors, unless the
notice specifies a later time for that resignation to become  effective.  If the
resignation  of a director is effective at a future time, the Board of Directors
may elect a successor to take office when the resignation becomes effective.

     Vacancies  in the Board of  Directors  may be filled by a  majority  of the
remaining  directors,  even  if  less  than a  quorum,  or by a  sole  remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares  represented and voting at a duly held meeting at which
a quorum is  present  (which  shares  voting  affirmatively  also  constitute  a
majority of the required  quorum).  Each  director so elected  shall hold office
until the next annual meeting of the stockholders and until a successor has been
elected and qualified.

     Unless  otherwise  provided in the  Certificate of  Incorporation  or these
bylaws:

                    (i) Vacancies and newly created directorships resulting from
                    any increase in the authorized  number of directors  elected
                    by all of the  stockholders  having  the  right to vote as a
                    single  class may be filled by a majority  of the  directors
                    then in office,  although  less than a quorum,  or by a sole
                    remaining director.

                    (ii)  Whenever  the holders of any class or classes of stock
                    or  series  thereof  are  entitled  to  elect  one  or  more
                    directors  by  the   provisions   of  the   Certificate   of
                    Incorporation,  vacancies and newly created directorships of
                    such  class or classes or series may be filled by a majority
                    of the directors  elected by such class or classes or series
                    thereof then in office,  or by a sole remaining  director so
                    elected.
<PAGE>

     If at any time,  by  reason of death or  resignation  or other  cause,  the
Corporation  should  have no  directors  in  office,  then  any  officer  or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary  entrusted with like  responsibility for the person or estate
of a stockholder,  may call a special meeting of stockholders in accordance with
the provisions of the Certificate of Incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

     If, at the time of filling any vacancy or any newly  created  directorship,
the directors then in office  constitute less than a majority of the whole board
(as  constituted  immediately  prior to any such  increase),  then the  Court of
Chancery may, upon  application of any  stockholder or  stockholders  holding at
least ten (10) percent of the total number of the shares at the time outstanding
having the right to vote for such  directors,  summarily order an election to be
held to fill any such  vacancies or newly created  directorships,  or to replace
the  directors  chosen  by the  directors  then in office  as  aforesaid,  which
election  shall be  governed  by the  provisions  of Section  211 of the General
Corporation Law of Delaware as far as applicable.

 3.5.     PLACE OF MEETINGS; MEETINGS BY TELEPHONE

who the person giving the notice has reason to believe will promptly communicate
it to the director.  The notice need not specify the purpose or the place of the
meeting,  if the meeting is to be held at the principal  executive office of the
Corporation.

          ------
     A majority of the authorized  number of directors shall constitute a quorum

of  these  bylaws.  Every  act or  decision  done or made by a  majority  of the
directors  present at a duly held meeting at which a quorum is present  shall be
regarded as the act of the Board of Directors,  subject to the provisions of the
Certificate of Incorporation and other applicable law.

     A meeting at which a quorum is  initially  present may continue to transact
business  notwithstanding  the  withdrawal of directors,  if any action taken is
approved by at least a majority of the required quorum for that meeting.

 3.9.     WAIVER OF NOTICE
          ----------------
     Notice  of a  meeting  need not be given to any  director  (i) who  signs a
waiver of notice or a consent  to holding  the  meeting  or an  approval  of the
minutes  thereof,  whether before or after the meeting,  or (ii) who attends the
meeting without  protesting,  prior thereto or at its commencement,  the lack of
notice to such  directors.  All such waivers,  consents,  and approvals shall be
filed with the corporate  records or made part of the minutes of the meeting.  A
waiver of notice need not specify the purpose of any regular or special  meeting
of the Board of Directors.

 3.10.    ADJOURNMENT

     A majority of the directors present,  whether or not constituting a quorum,

Directors. Such written consent and any counterparts thereof shall be filed with
the minutes of the proceedings of the Board.

Directors shall approve,  including,  without limitation,  a pledge of shares of
stock of the Corporation.  Nothing  contained in this section shall be deemed to

incurred in connection with any threatened,  pending or completed action,  suit,

of the Corporation, (ii) who is or was serving at the request of the Corporation

Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses  incurred by a director or officer of the  Corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an  undertaking  by the  director  or  officer  to repay all  amounts
advanced if it should  ultimately be determined  that the director of officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

     The rights  conferred on any person by this Article  shall not be exclusive
of any other rights which such person may have or  hereafter  acquire  under any
statute,  provision of the  Corporation's  Certificate of  Incorporation,  these
bylaws,  agreement,  vote of the  stockholders  or  disinterested  directors  or
otherwise.

     Any repeal or  modification  of the  foregoing  provisions  of this Article

respect of any act or  omission  occurring  prior to the time of such  repeal or
modification.

fines,  and amounts  paid in  settlement  actually  and  reasonably  incurred in
connection  with  any  threatened,   pending  or  completed  action,   suit,  or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such  person is or was an  employee or agent of
the  Corporation.  For purposes of this Section 6.2, an "employee" or "agent" of
the Corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the Corporation, (ii) who is or was serving at
the request of the  Corporation as an employee or agent of another  corporation,

corporation.

employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise  against any liability asserted against him or her and incurred

instance  where an  attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or

behalf of the  stockholder.  The  demand  under oath  shall be  directed  to the

                                 GENERAL MATTERS
                                 ---------------
 8.1.     RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
          -----------------------------------------------------
     For purposes of determining the stockholders entitled to receive payment of
any  dividend  or  other   distribution  or  allotment  of  any  rights  or  the
stockholders  entitled  to  exercise  any rights in respect of any other  lawful
action,  the Board of Directors may fix, in advance,  a record date, which shall
not be more than sixty  (60) days  before any such  action.  In that case,  only
stockholders  of  record  at the  close of  business  on the  date so fixed  are
entitled to receive the  dividend,  distribution  or allotment of rights,  or to
exercise such rights,  as the case may be,  notwithstanding  any transfer of any
shares on the books of the Corporation after the record date so fixed, except as
otherwise provided in the General Corporation Law of Delaware.

     If the Board of Directors  does not so fix a record  date,  then the record
date for determining  stockholders for any such purpose shall be at the close of
business on the day on which the Board adopts the applicable resolution.

 8.2.     CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS
          -----------------------------------------
     From time to time,  the Board of Directors  shall  determine by  resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money,  notes or other evidences of  indebtedness  that are issued in
the name of or payable to the  Corporation,  and only the persons so  authorized
shall sign or endorse those instruments.

 8.3.     CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED
          --------------------------------------------------
     The Board of Directors,  except as otherwise  provided in these bylaws, may
authorize  any  officer  or  officers,  or agent or  agents,  to enter  into any
contract  or  execute  any  instrument  in the  name  of and  on  behalf  of the
Corporation;  such  authority may be general or confined to specific  instances.
Unless so  authorized or ratified by the Board of Directors or within the agency
power of an  officer,  no  officer,  agent or  employee  shall have any power or
authority to bind the Corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.
<PAGE>

  8.4.     STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES
           ------------------------------------------------
     The  shares  of the  Corporation  shall  be  represented  by  certificates,
provided  that  the  Board  of  Directors  of the  Corporation  may  provide  by
resolution  or  resolutions  that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
Corporation.  Notwithstanding  the adoption of such a resolution by the Board of
Directors,  every holder of stock represented by certificates and, upon request,
every holder of uncertificated  shares,  shall be entitled to have a certificate
signed by, or in the name of the Corporation  by, the Chairman or  vice-chairman
of the  Board of  Directors,  or the  President  or  vice-president,  and by the
treasurer or an assistant treasurer,  or the Secretary or an assistant secretary
of such corporation  representing the number of shares registered in certificate
form. Any or all of the  signatures on the  certificate  may be a facsimile.  In
case any officer,  transfer agent or registrar who has signed or whose facsimile
signature  has been placed  upon a  certificate  has ceased to be such  officer,
transfer agent or registrar before such certificate is issued,  it may be issued
by the  Corporation  with the same  effect  as if he or she were  such  officer,
transfer agent or registrar at the date of issue.

     Certificates  for  shares  shall be of such form and device as the Board of
Directors  may  designate  and shall state the name of the record  holder of the
shares represented thereby;  its number; date of issuance;  the number of shares
for  which it is  issued;  a  summary  statement  or  reference  to the  powers,
designations,  preferences  or  other  special  rights  of  such  stock  and the
qualifications,  limitations or restrictions of such preferences  and/or rights,
if any;  a  statement  or  summary of liens,  if any;  a  conspicuous  notice of
restrictions  upon transfer or registration of transfer,  if any; a statement as
to any applicable  voting trust agreement;  if the shares be assessable,  or, if
assessments are collectible by personal action, a plain statement of such facts.

     Upon surrender to the Secretary or transfer  agent of the  Corporation of a
certificate  for shares  duly  endorsed  or  accompanied  by proper  evidence of
succession,  assignment  or authority  to transfer,  it shall be the duty of the
Corporation to issue a new  certificate to the person entitled  thereto,  cancel
the old certificate and record the transaction upon its books.

     The  Corporation  may issue  the whole or any part of its  shares as partly
paid and  subject  to call for the  remainder  of the  consideration  to be paid
therefor.  Upon the face or back of each stock  certificate  issued to represent
any such partly paid shares, or upon the books and records of the Corporation in
the  case  of  uncertificated  partly  paid  shares,  the  total  amount  of the
consideration  to be paid  therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the Corporation shall
declare a dividend upon partly paid shares of the same class,  but only upon the
basis of the percentage of the consideration actually paid thereon.


<PAGE>

 8.5.     SPECIAL DESIGNATION ON CERTIFICATES
          -----------------------------------
     If the  Corporation  is authorized to issue more than one class of stock or
more than one  series of any  class,  then the  powers,  the  designations,  the
preferences and the relative, participating, optional or other special rights of
each class of stock or series  thereof and the  qualifications,  limitations  or
restrictions  of such  preferences  and/or  rights shall be set forth in full or
summarized on the face or back of the  certificate  that the  Corporation  shall
issue to  represent  such  class or series of stock;  provided,  however,  that,
except as otherwise  provided in Section 202 of the General  Corporation  Law of
Delaware,  in lieu of the foregoing  requirements  there may be set forth on the
face or back of the certificate  that the  Corporation  shall issue to represent
such class or series of stock a  statement  that the  Corporation  will  furnish
without charge to each stockholder who so requests the powers, the designations,
the  preferences  and the  relative,  participating,  optional or other  special
rights  of each  class  of  stock  or  series  thereof  and the  qualifications,
limitations or restrictions of such preferences and/or rights.

 8.6.     LOST CERTIFICATES
          -----------------
     Except as provided in this  Section  8.6,  no new  certificates  for shares
shall be issued to replace a previously issued  certificate unless the latter is
surrendered  to the  Corporation  and  cancelled at the same time.  The Board of
Directors  may,  in case any  share  certificate  or  certificate  for any other
security is lost,  stolen or destroyed,  authorize  the issuance of  replacement
certificates  on such terms and  conditions as the Board may require;  the Board
may  require  indemnification  of the  Corporation  secured  by a bond or  other
adequate security  sufficient to protect the Corporation  against any claim that
may be made against it,  including any expense or  liability,  on account of the
alleged loss,  theft or  destruction  of the  certificate or the issuance of the
replacement certificate.

 8.7.     TRANSFER AGENTS AND REGISTRARS
          ------------------------------
     The Board of Directors may appoint one or more transfer  agents or transfer
clerks, and one or more registrars,  each of which shall be an incorporated bank
or trust company -- either  domestic or foreign,  who shall be appointed at such
times and places as the  requirements of the Corporation may necessitate and the
Board of Directors may designate.

 8.8.     CONSTRUCTION; DEFINITIONS
          -------------------------
     Unless the context requires  otherwise,  the general  provisions,  rules of
construction,  and definitions in the General  Corporation Law of Delaware shall
govern the construction of these bylaws. Without limiting the generality of this
provision,  the singular number includes the plural,  the plural number includes
the singular,  and the term "person"  includes both a corporation  and a natural
person.

     The original or other bylaws of the Corporation may be adopted,  amended or
repealed by the  stockholders  entitled to vote or by the Board of  Directors of
the  Corporation.  The fact  that  such  power  has been so  conferred  upon the
directors shall not divest the  stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

     Whenever an  amendment  or new bylaw is adopted,  it shall be copied in the
book of bylaws with the original bylaws, in the appropriate  place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

         6.       Limitations.
                  ------------
                  (a)               Each  Option  shall  be  designated  in  the
Notice of Grant as either an  Incentive  Stock  Option or a  Nonstatutory  Stock

aggregate Fair Market Value of Shares subject to an Optionee's  incentive  stock
options  granted  by  the  Company,  any  Parent  or  Subsidiary,  which  become
exercisable  for the first time during any calendar year (under all plans of the
Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall
be treated as  Nonstatutory  Stock  Options.  For purposes of this Section 6(a),
Incentive  Stock  Options shall be taken into account in the order in which they
were granted,  and the Fair Market Value of the Shares shall be determined as of
the time of grant.

                  (b)               Neither   the Plan nor  any Option or  Stock
Purchase  Right  shall  confer  upon an  Optionee  any  right  with  respect  to
continuing  the  Optionee's  employment  or  consulting  relationship  with  the
Company,  nor shall they interfere in any way with the  Optionee's  right or the
Company's right to terminate such  employment or consulting  relationship at any
time, with or without cause.

proportionately in connection with any change in the Company's capitalization as
described in Section 13(a).
<PAGE>

                           (iii)    If  an  Option  or  Stock Purchase  Right is
canceled (other than in connection with a transaction  described in Section 13),
the canceled  Option or Stock Purchase  Right will be counted  against the limit
set forth in Section  6(c)(i).  For this  purpose,  if the exercise  price of an
Option or Stock Purchase Right is reduced,  the transaction will be treated as a
cancellation of the Option or Stock Purchase Right and the grant of a new Option
or Stock Purchase Right.

         7.       Term of Plan.  Subject  to  Section  19 of the Plan,  the Plan

                  --------------
Notice of  Grant;  provided,  however,  that in the case of an  Incentive  Stock
Option,  the term shall be ten (10) years from the date of grant or such shorter
term as may be  provided  in the  Notice of Grant.  Moreover,  in the case of an
Incentive  Stock Option  granted to an Optionee  who, at the time the  Incentive
Stock Option is granted,  owns stock representing more than ten percent (10%) of
the  voting  power of all  classes  of stock of the  Company  or any  Parent  or
Subsidiary,  the term of the Incentive Stock Option shall be five (5) years from
the date of grant or such  shorter  term as may be  provided  in the  Notice  of
Grant.

any Parent or  Subsidiary,  the per Share  exercise  price shall be no less than
110% of the Fair Market Value per Share on the date of grant.

                                    (B)     granted to any  Employee othe   than
an Employee described in paragraph (A) immediately above, the per Share exercise
price shall be no less than 100% of the Fair Market  Value per Share on the date
of grant.

                           (ii)      In the case of a Nonstatutory Stock Option,
the per Share exercise price shall be determined by the Administrator.

                  (b)               Waiting Period and Exercise  Dates.   At the
                                    ----------------------------------
time an Option is granted,  the Administrator  shall fix the period within which
the Option may be exercised  and shall  determine any  conditions  which must be
satisfied before the Option may be exercised. In so doing, the Administrator may
specify that an Option may not be exercised  until the  completion  of a service
period.

                  (c)               Form of  Consideration.   The  Administrato
                                    ----------------------
shall determine the acceptable form of  consideration  for exercising an Option,
including the method of payment.  In the case of an Incentive Stock Option,  the
Administrator  shall determine the acceptable form of  consideration at the time
of grant. Such consideration may consist entirely of:

                           (i)      cash;

                           (ii)     check;

                           (iii)    promissory note;

                           (iv)     other Shares which (A) in the case of Share
acquired  upon  exercise of an option,  have been owned by the Optionee for more
than six months on the date of  surrender,  and (B) have a Fair Market  Value on
the date of surrender equal to the aggregate  exercise price of the Shares as to
which said Option shall be exercised;

                           (v)      delivery  of  a properly  executed  exercise
notice  together  with such other  documentation  as the  Administrator  and the
broker,  if  applicable,  shall  require to effect an exercise of the Option and
delivery  to the  Company  of the  sale or  loan  proceeds  required  to pay the
exercise price;

                           (vi)     a  reduction   in the  amount of any Company
liability  to  the  Optionee,   including  any  liability  attributable  to  the
Optionee's participation in any Company-sponsored  deferred compensation program
or arrangement;

                           (vii)    any combination of the foregoing methods  of
payment; or

                           (viii)   such   other  consideration  and  method  of
payment for the issuance of Shares to the extent permitted by Applicable Laws.

         10.      Exercise of Option.
                  ------------------
                  (a)               Procedure  for  Exercise;      Rights  as  a
                                    ------------------------
Shareholder.  Any Option granted hereunder shall be exercisable according to the
terms of the Plan and at such times and under such  conditions  as determined by
the Administrator and set forth in the Option Agreement.

                           An Option may not be  exercised  for a fraction  of a
Share.

                           An Option shall be deemed exercised when the  Company
receives:  (i)  written  notice  of  exercise  (in  accordance  with the  Option
Agreement)  from the person  entitled  to  exercise  the  Option,  and (ii) full
payment  for the Shares  with  respect to which the  Option is  exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator  and permitted by the Option Agreement and the Plan. Shares issued
upon  exercise of an Option  shall be issued in the name of the  Optionee or, if
requested  by the  Optionee,  in the name of the Optionee and his or her spouse.

<PAGE>

Until the stock  certificate  evidencing  such Shares is issued (as evidenced by
the  appropriate  entry on the  books  of the  Company  or of a duly  authorized
transfer  agent of the  Company),  no right to vote or receive  dividends or any
other rights as a  shareholder  shall exist with respect to the Optioned  Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock  certificate  promptly  after the Option is exercised.  No
adjustment  will be made for a dividend or other right for which the record date
is prior to the date the stock  certificate  is issued,  except as  provided  in
Section 13 of the Plan.

                                    Exercising  an  Option  in any  manner shall
decrease  the number of Shares  thereafter  available,  both for purposes of the
Plan and for sale  under  the  Option,  by the  number of Shares as to which the
Option is exercised.

                  (b)               Termination of Employment,    Consulting  or
                                    ------------------------
Outside  Director  Relationship.  Upon  termination of an Optionee's  Continuous
Status as an Employee, Consultant or Outside Director (but not in the event of a
change of status from Employee to Consultant or Outside  Director (in which case
an  Employee's   Incentive  Stock  Option  shall  automatically   convert  to  a
Nonstatutory  Stock Option on the ninety-first  (91st) day following such change
of status) or from Consultant or Outside Director to Employee),  other than upon
the Optionee's death or Disability, the Optionee may exercise his or her Option,
but only within such period of time as is specified in the Notice of Grant,  and
only to the extent that the  Optionee was entitled to exercise it at the date of
termination  (but in no  event  later  than the  expiration  of the term of such
Option as set forth in the Notice of Grant).  In the absence of a specified time
in the  Notice  of  Grant,  the  Option  shall  remain  exercisable  for 90 days
following the  Optionee's  termination  of  Continuous  Status as an Employee or
Consultant.  In the case of an Incentive Stock Option, such period of time shall
not exceed  ninety  (90) days from the date of  termination.  If, at the date of
termination,  the Optionee is not entitled to exercise his or her entire Option,
the Shares  covered by the  unexercisable  portion of the Option shall revert to
the Plan.  If,  after  termination,  the  Optionee  does not exercise his or her
Option  within  the  time  specified  by the  Administrator,  the  Option  shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                  (c)               Disability  of  Optionee. In the event  that
                                    ------------------------
an Optionee's  Continuous  Status as an Employee or  Consultant  terminates as a
result of the Optionee's Disability, the Optionee may exercise his or her Option
at any time within  twelve (12)  months from the date of such  termination,  but
only to the extent that the  Optionee was entitled to exercise it at the date of
such  termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant). If, at the date of termination, the
Optionee  is not  entitled  to  exercise  his or her entire  Option,  the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  termination,  the Optionee does not exercise his or her Option within the
time specified  herein,  the Option shall  terminate,  and the Shares covered by
such Option shall revert to the Plan.

                  (d)               Death of Optionee. In the event of the death
                                    -----------------
of an  Optionee,  the Option may be  exercised  at any time  within  twelve (12)
months following the date of death (but in no event later than the expiration of
the term of such Option as set forth in the Notice of Grant),  by the Optionee's
estate or by a person who  acquired  the right to exercise the Option by bequest
or  inheritance,  but only to the  extent  that the  Optionee  was  entitled  to
exercise the Option at the date of death. If, at the time of death, the Optionee
was not entitled to exercise his or her entire Option, the Shares covered by the
unexercisable  portion of the Option shall  immediately  revert to the Plan. If,
after  death,  the  Optionee's  estate  or a person  who  acquired  the right to
exercise  the Option by  bequest or  inheritance  does not  exercise  the Option
within the time specified  herein,  the Option shall  terminate,  and the Shares
covered by such Option shall revert to the Plan.

                  (e)               Rule 16b-3.   Options granted to individuals
                                    ----------
subject to Section 16 of the  Exchange  Act  ("Insiders")  must  comply with the
applicable provisions of Rule 16b-3 and shall contain such additional conditions
or  restrictions  as may be  required  thereunder  to  qualify  for the  maximum
exemption from Section 16 of the Exchange Act with respect to Plan transactions.

         11.      Stock Purchase Rights.
                  ---------------------
                  (a)               Rights to Purchase.   Stock  Purchase Rights
                                    ------------------
may be issued  either  alone,  in addition  to, or in tandem  with other  awards
granted  under the Plan and/or cash awards made  outside of the Plan.  After the
Administrator  determines  that it will offer Stock  Purchase  Rights  under the
Plan, it shall advise the offeree in writing,  by means of a Notice of Grant, of
the terms,  conditions  and  restrictions  related to the offer,  including  the
number of Shares that the offeree shall be entitled to purchase, the price to be
paid, and the time within which the offeree must accept such offer,  which shall
in no event  exceed  six (6) months  from the date upon which the  Administrator
made the  determination  to grant the Stock Purchase  Right.  The offer shall be
accepted by  execution  of a  Restricted  Stock  Purchase  Agreement in the form
determined by the Administrator.

                  (b)               Repurchase     Option.       Unless      the
                                    ---------------------
Administrator  determines  otherwise,  the Restricted  Stock Purchase  Agreement
shall grant the Company a repurchase  option  exercisable  upon the voluntary or
involuntary  termination of the purchaser's  employment with the Company for any
reason   (including  death  or  Disability).   The  purchase  price  for  Shares
repurchased  pursuant to the Restricted  Stock purchase  agreement  shall be the
original  price paid by the  purchaser  and may be paid by  cancellation  of any
indebtedness of the purchaser to the Company.  The repurchase option shall lapse
at a rate determined by the Administrator.

                  (c)               Rule  16b-3. Stock  Purchase Rights  granted
                                    -----------
to Insiders,  and Shares purchased by Insiders in connection with Stock Purchase
Rights,  shall be subject to any restrictions  applicable  thereto in compliance
with Rule 16b-3.  An Insider may only purchase Shares pursuant to the grant of a
Stock Purchase Right, and may only sell Shares  purchased  pursuant to the grant
of a Stock  Purchase  Right,  during such time or times as are permitted by Rule
16b-3.

                  (d)               Other  Provisions.    The  Restricted  Stock
                                    -----------------
Purchase Agreement shall contain such other terms, provisions and conditions not
inconsistent with the Plan as may be determined by the Administrator in its sole
discretion.  In addition, the provisions of Restricted Stock Purchase Agreements
need not be the same with respect to each purchaser.
<PAGE>

                  (e)               Rights as a Shareholder.   Once  the   Stock
                                    -----------------------
Purchase Right is exercised,  the purchaser shall have the rights  equivalent to
those of a shareholder,  and shall be a shareholder  when his or her purchase is
entered upon the records of the duly  authorized  transfer agent of the Company.
No  adjustment  will be made for a dividend  or other right for which the record
date is prior to the date the  Stock  Purchase  Right is  exercised,  except  as
provided in Section 13 of the Plan.

         12.      Non-Transferability of Options and Stock  Purchase Rights.  An
                  ---------------------------------------------------------
Option or Stock Purchase Right may not be sold, pledged, assigned, hypothecated,
transferred,  or disposed of in any manner  other than by will or by the laws of
descent  or  distribution  and may be  exercised,  during  the  lifetime  of the
Optionee, only by the Optionee.

         13.      Adjustments  Upon  Changes  in  Capitalization,   Dissolution,
                  --------------------------------------------------------------
Merger, Asset Sale or Change of Control.
- - ----------------------------------------
                  (a)               Changes in Capitalization.  Subject  to  any
                                    -------------------------
required  action by the  shareholders  of the  Company,  the number of shares of
Common Stock covered by each  outstanding  Option and Stock Purchase Right,  and
the number of shares of Common  Stock which have been  authorized  for  issuance
under the Plan but as to which no Options or Stock Purchase Rights have yet been
granted or which have been returned to the Plan upon  cancellation or expiration
of an Option or Stock Purchase  Right,  as well as the price per share of Common
Stock covered by each such outstanding  Option or Stock Purchase Right, shall be
proportionately  adjusted  for any  increase or decrease in the number of issued
shares of Common Stock resulting from a stock split,  reverse stock split, stock
dividend,  combination  or  reclassification  of the Common Stock,  or any other
increase  or decrease in the number of issued  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 issuance 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 an
Option or Stock Purchase Right.

                  (b)               Dissolution  or   Liquidation.  In the event
                                    -----------------------------
of the proposed dissolution or liquidation of the Company, to the extent that an
Option  or Stock  Purchase  Right  has not been  previously  exercised,  it will
terminate  immediately  prior to the consummation of such proposed  action.  The
Board may, in the exercise of its sole  discretion  in such  instances,  declare
that any Option or Stock  Purchase  Right shall  terminate as of a date fixed by
the Board and give each  Optionee  the right to  exercise  his or her  Option or
Stock  Purchase  Right as to all or any part of the  Optioned  Stock,  including
Shares as to which the Option or Stock  Purchase  Right would not  otherwise  be
exercisable.
<PAGE>

                  (c)               Merger or Asset Sale.    In  the event  of a
                                    --------------------
merger  of the  Company  with  or  into  another  corporation,  or the  sale  of
substantially  all of the assets of the  Company,  each  outstanding  Option and
Stock Purchase Right shall be assumed or an equivalent  option or right shall be
substituted  by the  successor  corporation  or a Parent  or  Subsidiary  of the
successor  corporation.  The  Administrator  may, in lieu of such  assumption or
substitution,  provide for the Optionee to have the right to exercise the Option
or Stock Purchase Right as to all or a portion of the Optioned Stock,  including
Shares as to which it would not otherwise be exercisable.  If the  Administrator
makes an Option or Stock  Purchase  Right  exercisable  in lieu of assumption or
substitution in the event of a merger or sale of assets, the Administrator shall
notify the  Optionee  that the  Option or Stock  Purchase  Right  shall be fully
exercisable for a period of fifteen (15) days from the date of such notice,  and
the Option or Stock  Purchase  Right will  terminate upon the expiration of such
period.  For the purposes of this paragraph,  the Option or Stock Purchase Right
shall be  considered  assumed if,  following  the merger or sale of assets,  the
option or right confers the right to purchase,  for each Share of Optioned Stock
subject to the Option or Stock Purchase Right immediately prior to the merger or
sale of assets,  the consideration  (whether stock, cash, or other securities or
property)  received  in the merger or sale of assets by holders of Common  Stock
for each Share held on the  effective  date of the  transaction  (and if holders
were offered a choice of consideration,  the type of consideration chosen by the
holders of a majority of the outstanding  Shares);  provided,  however,  that if
such  consideration  received  in the  merger or sale of assets  was not  solely
common stock of the successor  corporation or its Parent, the Administrator may,
with the consent of the successor corporation,  provide for the consideration to
be received upon the exercise of the Option or Stock  Purchase  Right,  for each
Share of Optioned  Stock subject to the Option or Stock  Purchase  Right,  to be
solely  common stock of the  successor  corporation  or its Parent equal in fair
market value to the per share consideration  received by holders of Common Stock
in the merger or sale of assets.

         14.      Date of Grant.    The date of  grant  of  an  Option  or Stock
                  -------------
Purchase Right shall be, for all purposes,  the date on which the  Administrator
makes the  determination  granting such Option or Stock Purchase  Right, or such
other  later  date  as  is  determined  by  the  Administrator.  Notice  of  the
determination  shall be provided to each Optionee within a reasonable time after
the date of such grant.

         15.      Amendment and Termination of the Plan.
                  -------------------------------------
                  (a)               Amendment and Termination.  The Board may at
                                    -------------------------
any time amend, alter, suspend or terminate the Plan.

                  (b)              Shareholder   Approval.  The  Company   shall
                                   ----------------------
obtain  shareholder  approval of any Plan amendment to the extent  necessary and
desirable  to comply  with Rule  16b-3 or with  Section  422 of the Code (or any
successor rule or statute or other applicable law, rule or regulation, including
the  requirements of any exchange or quotation  system on which the Common Stock
is listed or quoted). Such shareholder approval, if required,  shall be obtained
in such a manner and to such a degree as is required by the applicable law, rule
or regulation.

                  (c)               Effect     of   Amendment  or   Termination.
                                    --------------------------------------------
No amendment, alteration, suspension or termination of the Plan shall impair the
rights of any Optionee,  unless mutually agreed  otherwise  between the Optionee
and the  Administrator,  which  agreement  must be in writing  and signed by the
Optionee and the Company.
<PAGE>

         16.      Conditions Upon Issuance of Shares.
                  -----------------------------------
                  (a)               Legal  Compliance.   Shares   shall  no   be
                                    -----------------
issued  pursuant to the exercise of an Option or Stock Purchase Right unless the
exercise of such Option or Stock Purchase Right and the issuance and delivery of
such Shares shall comply with all relevant provisions of law, including, without
limitation,  the Securities Act of 1933, as amended, the Exchange Act, the rules
and regulations promulgated thereunder, Applicable Laws, and the requirements of
any stock exchange or quotation  system upon which the Shares may then be listed
or quoted,  and shall be  further  subject to the  approval  of counsel  for the
Company with respect to such compliance.

                  (b)               Investment Representations.   As a condition
                                    --------------------------
to the exercise of an Option or Stock  Purchase  Right,  the Company may require
the person  exercising  such Option or Stock  Purchase  Right to  represent  and
warrant at the time of any 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.

         17.      Liability of Company.
                  ---------------------
                  (a)               Inability to Obtain Authority. The inability
                                    ------------------------------
of the Company to obtain authority from any regulatory body having jurisdiction,
which authority is deemed by the Company's counsel to be necessary to the lawful
issuance  and sale of any Shares  hereunder,  shall  relieve  the Company of any
liability  in  respect of the  failure to issue or sell such  Shares as to which
such requisite authority shall not have been obtained.

                  (b)               Grants  Exceeding  Allotted Shares.  If  the
                                    ----------------------------------
Optioned Stock covered by an Option or Stock  Purchase Right exceeds,  as of the
date of grant,  the number of Shares  which may be issued under the Plan without
additional  shareholder  approval,  such Option or Stock Purchase Right shall be
void with respect to such excess Optioned Stock, unless shareholder  approval of
an amendment sufficiently increasing the number of Shares subject to the Plan is
timely obtained in accordance with Section 15(b) of the Plan.

         18.      Reservation of Shares.  The Company,   during the term of this
                  ---------------------
Plan,  will at all times  reserve  and keep  available  such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.

         19.      Shareholder Approval. Continuance of the Plan shall be subject
                  --------------------
to approval by the  shareholders of the Company within twelve (12) months before
or after  the  date the Plan is  adopted.  Such  shareholder  approval  shall be
obtained in the manner and to the degree required under  applicable  federal and
state law.

Option.  However,  notwithstanding  such  designations,  to the extent  that the

options  granted  by  the  Company,  any  Parent  or  Subsidiary,  which  become
exercisable  for the first time during any calendar year (under all plans of the

the time of grant.

                  (b)               Neither the Plan nor any Option shall confer
upon an Optionee any right with respect to continuing the Optionee's  employment
or consulting relationship with the Company, nor shall they interfere in any way

consulting relationship at any time, with or without cause.

                           (iii)    If  an  Option  is  canceled  (other than in
connection with a transaction described in Section 12), the canceled Option will
be counted against the limit set forth in Section 6(c)(i).  For this purpose, if

cancellation of the Option and the grant of a new Option.

Incentive  Stock Option  granted to an Optionee  who, at the time the  Incentive
Stock Option is granted,  owns stock representing more than ten percent (10%) of
the  voting  power of all  classes  of stock of the  Company  or any  Parent  or
Subsidiary,  the term of the Incentive Stock Option shall be five (5) years from

Grant.

Option, the per Share exercise price shall be determined by the Administrator.

                  (b) Waiting Period and Exercise  Dates.  At the time an Option

acquired  upon  exercise of an option,  have been owned by the Optionee for more
than six months on the date of  surrender,  and (B) have a Fair Market  Value on
the date of surrender equal to the aggregate  exercise price of the Shares as to
which said Option shall be exercised;

                           (v)      delivery  of  a  properly  executed exercise
notice  together  with such other  documentation  as the  Administrator  and the
broker,  if  applicable,  shall  require to effect an exercise of the Option and
delivery  to the  Company  of the  sale or  loan  proceeds  required  to pay the
exercise price;

                           (vi)     a  reduction  in the amount  of any  Company
liability  to  the  Optionee,   including  any  liability  attributable  to  the
Optionee's participation in any Company-sponsored  deferred compensation program
or arrangement;

                           (vii)    any combination  of the foregoing methods of
payment; or

                           (viii)   such   other  consideration  and  method  of
payment for the issuance of Shares to the extent permitted by Applicable Laws.

         10.      Exercise of Option.
                  ------------------
                  (a)               Procedure  for  Exercise;     Rights  as   a
Shareholder.  Any Option granted hereunder shall be exercisable according to the
terms of the Plan and at such times and under such  conditions  as determined by
the Administrator and set forth in the Option Agreement.

                           An Option may not be  exercised  for a fraction  of a
Share.

                           An Option shall be deemed exercised when the  Company
receives:  (i)  written  notice  of  exercise  (in  accordance  with the  Option
Agreement)  from the person  entitled  to  exercise  the  Option,  and (ii) full
payment  for the Shares  with  respect to which the  Option is  exercised.  Full
payment may consist of any consideration and method of payment authorized by the
<PAGE>
Administrator  and permitted by the Option Agreement and the Plan. Shares issued
upon  exercise of an Option  shall be issued in the name of the  Optionee or, if
requested  by the  Optionee,  in the name of the Optionee and his or her spouse.
Until the stock  certificate  evidencing  such Shares is issued (as evidenced by
the  appropriate  entry on the  books  of the  Company  or of a duly  authorized
transfer  agent of the  Company),  no right to vote or receive  dividends or any
other rights as a  shareholder  shall exist with respect to the Optioned  Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock  certificate  promptly  after the Option is exercised.  No
adjustment  will be made for a dividend or other right for which the record date
is prior to the date the stock  certificate  is issued,  except as  provided  in
Section 12 of the Plan.

                           Exercising an Option in any manner shall decrease the
number of Shares  thereafter  available,  both for  purposes of the Plan and for
sale  under the  Option,  by the  number  of  Shares  as to which the  Option is
exercised.

                  (b)               Termination  of  Employment,   Consulting or
                                    --------------------------------------------
 Outside Director Relationship. Upon  termination  of an  Optionee's  Continuous
- - -----------------------------
Status as anEmployee,  Consultant or Outside Director (but not in the event of a
change of status from Employee to Consultant or Outside  Director (in which case
an  Employee's   Incentive  Stock  Option  shall  automatically   convert  to  a
Nonstatutory  Stock Option on the ninety-first  (91st) day following such change
of status) or from Consultant or Outside Director to Employee),  other than upon
the Optionee's death or Disability, the Optionee may exercise his or her Option,
but only within such period of time as is specified in the Notice of Grant,  and
only to the extent that the  Optionee was entitled to exercise it at the date of
termination  (but in no  event  later  than the  expiration  of the term of such
Option as set forth in the Notice of Grant).  In the absence of a specified time
in the  Notice  of  Grant,  the  Option  shall  remain  exercisable  for 90 days
following the  Optionee's  termination  of  Continuous  Status as an Employee or
Consultant.  In the case of an Incentive Stock Option, such period of time shall
not exceed  ninety  (90) days from the date of  termination.  If, at the date of
termination,  the Optionee is not entitled to exercise his or her entire Option,
the Shares  covered by the  unexercisable  portion of the Option shall revert to
the Plan.  If,  after  termination,  the  Optionee  does not exercise his or her
Option  within  the  time  specified  by the  Administrator,  the  Option  shall
terminate,  and the Shares  covered  by such  Option  shall  revert to the Plan.
Notwithstanding   the  foregoing,   Options   granted  in  connection  with  the
acquisition of assets of Bipolar Integrated  Technology,  Inc. shall be governed
by the provisions concerning events upon termination of Employment stated in the
option agreements evidencing such Options.

                  (c)               Disability  of  Optionee.  In the event that
                                    ------------------------
an Optionee's  Continuous  Status as an Employee or  Consultant  terminates as a
result of the Optionee's Disability, the Optionee may exercise his or her Option
at any time within  twelve (12)  months from the date of such  termination,  but
only to the extent that the  Optionee was entitled to exercise it at the date of
such  termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant). If, at the date of termination, the
Optionee  is not  entitled  to  exercise  his or her entire  Option,  the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after  termination,  the Optionee does not exercise his or her Option within the
time specified  herein,  the Option shall  terminate,  and the Shares covered by
such Option shall revert to the Plan.
<PAGE>

                  (d)               Death of Optionee. In the event of the death
                                    -----------------
of an  Optionee,  the Option may be  exercised  at any time  within  twelve (12)
months following the date of death (but in no event later than the expiration of
the term of such Option as set forth in the Notice of Grant),  by the Optionee's
estate or by a person who  acquired  the right to exercise the Option by bequest
or  inheritance,  but only to the  extent  that the  Optionee  was  entitled  to
exercise the Option at the date of death. If, at the time of death, the Optionee
was not entitled to exercise his or her entire Option, the Shares covered by the
unexercisable  portion of the Option shall  immediately  revert to the Plan. If,
after  death,  the  Optionee's  estate  or a person  who  acquired  the right to
exercise  the Option by  bequest or  inheritance  does not  exercise  the Option
within the time specified  herein,  the Option shall  terminate,  and the Shares
covered by such Option shall revert to the Plan.

                  (e)               Rule 16b-3. Options  granted  to individuals
                                    ----------
subject to Section 16 of the  Exchange  Act  ("Insiders")  must  comply with the
applicable provisions of Rule 16b-3 and shall contain such additional conditions
or  restrictions  as may be  required  thereunder  to  qualify  for the  maximum
exemption from Section 16 of the Exchange Act with respect to Plan transactions.

         11.      Non-Transferability of Options. An  Option  may  not  be sold,
                  ------------------------------
pledged,assigned,  hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent  or  distribution  and may be  exercised,
during the lifetime of the Optionee, only by the Optionee.

         12.      Adjustments  Upon  Changes  in  Capitalization,   Dissolution,
                  -------------------------------------------------------------
 Merger, Asset Sale or Change of Control.
- - -----------------------------------------
                  (a)               Changes in Capitalization.  Subject  to  any
                                    -------------------------
required  action by the  shareholders  of the  Company,  the number of shares of
Common Stock  covered by each  outstanding  Option,  and the number of shares of
Common Stock which have been  authorized  for issuance  under the Plan but as to
which no Options have yet been  granted or which have been  returned to the Plan
upon  cancellation or expiration of an Option, as well as the price per share of
Common Stock covered by each such outstanding  Option,  shall be proportionately
adjusted for any  increase or decrease in the number of issued  shares of Common
Stock  resulting  from a stock  split,  reverse  stock  split,  stock  dividend,
combination or  reclassification  of the Common Stock,  or any other increase or
decrease in the number of issued 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 issuance 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 an Option.

                  (b)               Dissolution or  Liquidation. In the event of
                                    ---------------------------
the proposed  dissolution or  liquidation of the Company,  to the extent that an
Option has not been previously exercised, it will terminate immediately prior to
the consummation of such proposed action.  The Board may, in the exercise of its
sole discretion in such instances, declare that any Option shall terminate as of
a date fixed by the Board and give each  Optionee  the right to exercise  his or
her Option as to all or any part of the Optioned Stock,  including  Shares as to
which the Option would not otherwise be exercisable.
<PAGE>

                  (c)               Merger or Asset Sale.  In  the  event  of  a
                                    --------------------
merger  of the  Company  with  or  into  another  corporation,  or the  sale  of
substantially all of the assets of the Company, each outstanding Option that was
granted as  substitution  of  non-qualified  options to purchase common stock of
Bipolar Integrated  Technology,  Inc. shall become exercisable  immediately upon
the closing of such  transaction  as to all or a portion of the Optioned  Stock,
including  Shares as to which it would not otherwise be  exercisable.  Any other
outstanding  Option  and  each  Stock  Purchase  Right  shall be  assumed  or an
equivalent option or right shall be substituted by the successor  corporation or
a Parent or Subsidiary of the successor  corporation.  The Administrator may, in
lieu of such  assumption or  substitution,  provide for the Optionee to have the
right to exercise the Option or Stock  Purchase  Right as to all or a portion of
the  Optioned  Stock,  including  Shares as to which it would not  otherwise  be
exercisable.  If the  Administrator  makes an  Option  or Stock  Purchase  Right
exercisable  in lieu of assumption or  substitution  in the event of a merger or
sale of assets,  the Administrator  shall notify the Optionee that the Option or
Stock  Purchase  Right shall be fully  exercisable  for a period of fifteen (15)
days from the date of such notice,  and the Option or Stock  Purchase Right will
terminate  upon  the  expiration  of  such  period.  For  the  purposes  of this
paragraph,  the Option or Stock Purchase  Right shall be considered  assumed if,
following the merger or sale of assets, the option or right confers the right to
purchase,  for each  Share of  Optioned  Stock  subject  to the  Option or Stock
Purchase  Right  immediately  prior  to  the  merger  or  sale  of  assets,  the
consideration (whether stock, cash, or other securities or property) received in
the merger or sale of assets by  holders of Common  Stock for each Share held on
the effective date of the  transaction  (and if holders were offered a choice of
consideration,  the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided,  however, that if such consideration received
in the  merger or sale of assets was not solely  common  stock of the  successor
corporation  or its  Parent,  the  Administrator  may,  with the  consent of the
successor  corporation,  provide for the  consideration  to be received upon the
exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock
subject to the Option or Stock Purchase  Right, to be solely common stock of the
successor  corporation or its Parent equal in fair market value to the per share
consideration  received  by  holders  of Common  Stock in the  merger or sale of
assets.


         13.      Date of Grant.  The date of grant of an Option  shall be,  for
                  ------------
all  purposes,  the date on which  the  Administrator  makes  the  determination
granting  such  Option,  or  such  other  later  date  as is  determined  by the
Administrator.  Notice of the  determination  shall be provided to each Optionee
within a reasonable time after the date of such grant.

         14.      Amendment and Termination of the Plan.
                  -------------------------------------
                  (a)               Amendment and Termination.  The Board may at
                                    -------------------------
any time amend, alter, suspend or terminate the Plan.
<PAGE>
                  (b)               Shareholder  Approval.   The  Company  shall
                                    ---------------------
obtain  shareholder  approval of any Plan  amendment to the extent  necessary to
comply with Section 422 of the Code (or any  successor  rule or statute or other
applicable law, rule or regulation,  including the  requirements of any exchange
or  quotation  system on which the  Common  Stock is  listed  or  quoted).  Such
shareholder  approval,  if  required,  shall be obtained in such a manner and to
such a degree as is required by the applicable law, rule or regulation.

                  (c)               Effect  of  Amendment or  Termination.    No
                                    -------------------------------------
amendment,  alteration,  suspension or  termination of the Plan shall impair the
rights of any Optionee,  unless mutually agreed  otherwise  between the Optionee
and the  Administrator,  which  agreement  must be in writing  and signed by the
Optionee and the Company.

         15.      Conditions Upon Issuance of Shares.
                  ----------------------------------
                  (a)               Legal Compliance. Shares shall not b  issued
                                    ----------------
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and  delivery of such Shares shall comply with all relevant  provisions
of law, including,  without limitation,  the Securities Act of 1933, as amended,
the Exchange Act, the rules and regulations promulgated  thereunder,  Applicable
Laws, and the  requirements of any stock exchange or quotation system upon which
the  Shares may then be listed or  quoted,  and shall be further  subject to the
approval of counsel for the Company with respect to such compliance.

                  (b)               Investment Representations.  As a  condition
                                    --------------------------
to the exercise of an Option, the Company may require the person exercising such
Option to represent and warrant at the time of any 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.

<PAGE>

         16.      Liability of Company.
                  ---------------------
                  (a)               Inability to Obtain Authority. The inability
                                    ------------------------------
of the Company to obtain authority from any regulatory body having jurisdiction,
which authority is deemed by the Company's counsel to be necessary to the lawful
issuance  and sale of any Shares  hereunder,  shall  relieve  the Company of any
liability  in  respect of the  failure to issue or sell such  Shares as to which
such requisite authority shall not have been obtained.

                  (b)               Grants  Exceeding Allotted Shares.   If  the
                                    ---------------------------------
Optioned Stock covered by an Option exceeds, as of the date of grant, the number
of Shares  which may be issued  under the Plan  without  additional  shareholder
approval,  such Option shall be void with respect to such excess Optioned Stock,
unless shareholder approval of an amendment  sufficiently  increasing the number
of Shares  subject to the Plan is timely  obtained in  accordance  with  Section
14(b) of the Plan.

         17.      Reservation of Shares.  The Company,  during the  term of this
                  ---------------------
Plan,  will at all times  reserve  and keep  available  such number of Shares as
shall be sufficient to satisfy the requirements of the Plan.
