              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT



Item 3.  Incorporation of Documents by Reference
         ---------------------------------------

     P-COM, Inc. (the "Registrant") hereby incorporates by reference into this
Registration Statement the following documents previously filed with the
Securities and Exchange Commission (the "SEC"):

     (a)  The Registrant's Annual Report on Form 10-K for the fiscal year ended
          December 31, 1997, filed with the SEC on March 31, 1998 and amended on
          May 6, 1998; and

     (b)  The Registrant's Quarterly Report on Form 10-Q for the fiscal quarter
          ended March 31, 1998, filed with the SEC on May 15, 1998;

     (c)  The Registrant's Current Reports on Forms 8-K, filed with the SEC on
          April 9, 1998 and April 17, 1998, respectively;

     (d)  The Registrant's Registration Statement No. 0-25356 on Form 8-A, filed
          with the SEC on January 12, 1995 pursuant to Section 12 of the
          Securities Exchange Act of 1934, as amended (the 1934 Act") in which
          there is described the terms, rights and provisions applicable to the
          Registrant's outstanding Common Stock.

     All reports and definitive proxy or information statements filed pursuant
to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all securities offered hereby have been sold or which de-
registers all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents.  Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed
document which also is deemed to be incorporated by reference herein modifies or
supersedes such statement.  Any such statement so modified or superseded shall
not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

Item 4.  Description of Securities
         -------------------------

     Not Applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------

     Not Applicable.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

     The Registrant's Certificate of Incorporation limits the liability of
directors to the maximum extent permitted by Delaware law.  Delaware law
provides that directors of a corporation will not be personally liable for
monetary damages for breach of their fiduciary duties as directors, except for
liability for (i) any breach of their duty of loyalty to the corporation or its
stockholders, (ii) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) unlawful payments of
dividends or unlawful stock repurchases or redemptions

                                      II-1
<PAGE>
 
as provided in Section 174 of the Delaware General Corporation Law, or (iv) any
transaction from which the director derives an improper personal benefit.

     The Registrant's Bylaws provide that the Registrant shall indemnify its
directors and may indemnify its officers, employees and other agents to the
fullest extent permitted by law.  The Registrant believes that indemnification
under its Bylaws covers at least negligence and gross negligence on the part of
an indemnified party in connection with the defense of any action or proceeding
arising out of such party's status or service as a director, officer, employee
or other agent of the Company upon an undertaking by such party to repay such
advances if it is ultimately determined that such party is not entitled to
indemnification.

     The Registrant has entered into separate indemnification agreements with
each of its directors and officers.  These agreements require the Registrant,
among other things, to indemnify such director or officer against expenses
(including attorneys' fees), judgments, fines and settlements (collectively,
"Liabilities") paid by such individual in connection with any action, suit or
proceeding arising out of such individual's status or service as a director or
officer of the Registrant (other than Liabilities arising from willful
misconduct or conduct that is knowingly fraudulent or deliberately dishonest)
and to advance expenses incurred by such individual in connection with any
proceeding against such individual with respect to which such individual may be
entitled to indemnification by the Registrant.

Item 9.  Undertakings
         ------------

         A.    The undersigned Registrant hereby undertakes:  (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts
or events arising after the effective date of this Registration Statement (or
the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
                        --------                                                
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof; and (3) to remove
from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the Registrant's 1995
Stock Option/Stock Issuance Plan and/or Employee Stock Purchase Plan.

         B.    The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into this Registration Statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         C.  Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the SEC, such
indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

                Aggregate of 3,750,000 Shares of Common Stock
                -------------------------------------------------------

Dear Ladies and Gentlemen:

  We have acted as counsel to P-COM, Inc., a Delaware corporation (the
"Company"), in connection with the registration on Form S-8 (the "Registration
Statement") under the Securities Act of 1933, as amended, of (i) an additional
3,500,000 shares of the Company's common stock for issuance under the Company's
1995 Stock Option/Stock Issuance Plan (the "Option Plan") and (ii) 250,000
shares of the Company's common stock for issuance under the Company's Employee
Stock Purchase Plan (the "Purchase Plan").

  This opinion is being furnished in accordance with the requirements of Item 8
of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.

  We have reviewed the Company's charter documents and the corporate proceedings
taken by the Company in connection with the establishment and amendment of the
Option Plan and of the Purchase Plan.  Based on such review, we are of the
opinion that, if, as and when the shares of the Company's common stock are
issued and sold (and the consideration therefor received) pursuant to (a) the
provisions of option agreements duly authorized under the Option Plan and/or the
Purchase Plan and in accordance with the Registration Statement, or (b) duly
authorized direct stock issuances in accordance with the Option Plan and/or
Purchase Plan and in accordance with the Registration Statement, such shares
will be duly authorized, legally issued, fully paid and nonassessable.

  We consent to the filing of this opinion letter as Exhibit 5 to the
Registration Statement.

  This opinion letter is rendered as of the date first written above, and we
disclaim any obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinion expressed herein.  Our opinion is expressly
limited to the matters set forth above, and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company, the
Option Plan, the Purchase Plan, or the shares of the Company's common stock
issuable under such plans or options.

                Very truly yours,


                /s/ BROBECK, PHLEGER & HARRISON LLP

                    1995 STOCK OPTION/STOCK ISSUANCE PLAN
                    -------------------------------------

          (As Amended and Restated Effective as of March 11, 1998)


                                 ARTICLE ONE

                             GENERAL PROVISIONS
                             ------------------

     I.   PURPOSE OF THE PLAN

          This 1995 Stock Option/Stock Issuance Plan is intended to promote the
interests of P-COM, Inc., a Delaware corporation, by providing eligible persons
with the opportunity to acquire a proprietary interest, or otherwise increase
their proprietary interest, in the Corporation as an incentive for them to
remain in the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.
 
     II.  STRUCTURE OF THE PLAN

          A.  The Plan shall be divided into three separate equity programs:

               (i)   the Discretionary Option Grant Program under which eligible
     persons may, at the discretion of the Plan Administrator, be granted
     options to purchase shares of Common Stock,

               (ii)  the Stock Issuance Program under which eligible persons
     may, at the discretion of the Plan Administrator, be issued shares of
     Common Stock directly, either through the immediate purchase of such
     shares or as a bonus for services rendered the Corporation (or any Parent
     or Subsidiary), and

               (iii) the Automatic Option Grant Program under which Eligible
     Directors shall automatically receive option grants at periodic intervals
     to purchase shares of Common Stock.

          B.   The provisions of Articles One and Five shall apply to all equity
programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.
<PAGE>
 
     III. ADMINISTRATION OF THE PLAN

          A.   The Primary Committee shall have sole and exclusive authority to
administer the Discretionary Option Grant and Stock Issuance Programs with
respect to Section 16 Insiders.  Except to the extent the Primary Committee is
granted sole and exclusive authority under one or more specific provisions of
the Plan, administration of the Discretionary Option Grant and Stock Issuance
Programs with respect to all other persons eligible to participate in these
programs may, at the Board's discretion, be vested in the Primary Committee or a
Secondary Committee, or the Board may retain the power to administer those
programs with respect to all such persons.  The members of the Secondary
Committee may be individuals who are Employees eligible to receive discretionary
option grants or direct stock issuances under the Plan or any stock option,
stock appreciation, stock bonus or other stock plan of the Corporation (or any
Parent or Subsidiary).

          B.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and shall be subject to
removal by the Board at any time.  The Board may also at any time terminate the
functions of any Secondary Committee and reassume all powers and authority
previously delegated to such committee.

          C.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of such programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable.  Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant or Stock Issuance Program under its jurisdiction or
any option or stock issuance thereunder.

          D.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee.  No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

          E.   Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to option
grants made thereunder.

                                       2.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

               (i)    Employees,

               (ii)   non-employee members of the Board or of the board of
     directors of any Parent or Subsidiary, and

               (iii)  consultants or other independent advisors who provide
     services to the Corporation (or any Parent or Subsidiary).

          B.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive option grants, the time or times
when such option grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times at which each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
to be paid by the Participant for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          D.   The individuals eligible to receive option grants under the
Automatic Option Grant Program shall be limited to (i) those individuals who
were serving as non-employee Board members on February 1, 1996, (ii) those
individuals who first become non-employee Board members after February 1, 1996,
whether through appointment by the Board or election by the Corporation's
stockholders, and (iii) those individuals who continue to serve as non-employee
Board members at one or more Annual Stockholders Meetings held after February 1,
1996.  A non-employee Board member who has previously been in the employ of the
Corporation (or any Parent or Subsidiary) shall not be eligible to receive an
initial 40,000-share option grant under the Automatic Option Grant Program at
the time he or she first becomes a non-employee Board member, but such
individual shall be eligible to receive periodic option grants under the
Automatic Option Grant Program upon his or her continued service as a non-
employee Board member.

                                       3.

     V.  STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market.  The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed 12,719,625/1/
shares.  Such authorized share reserve is comprised of (i) the number of shares
which remained available for issuance, as of the Plan Effective Date, under the
Predecessor Plan as last approved by the Corporation's stockholders prior to
such date, including the shares subject to the outstanding options incorporated
into the Plan and any other shares which would have been available for future
option grants under the Predecessor Plan, (ii) an additional increase of 640,000
shares of Common Stock previously authorized by the Board and approved by the
Corporation's stockholders prior to the Plan Effective Date, (iii) an additional
increase of 1,600,000 shares of Common Stock authorized by the Board on February
1, 1996 and approved by the Corporation's stockholders at the 1996 Annual
Meeting, (iv) a further increase of 3,000,000 shares of Common Stock authorized
by the Board in April 1997 and approved by the stockholders at the 1997 Annual
Meeting, (v) the 683,737 shares of Common Stock added to the share reserve on
January 2, 1998 by reason of the automatic share increase provisions of Section
V.B of this Article One plus (vi) a further increase of 3,500,000 shares of
Common Stock authorized by the Board on March 11, 1998 and subject to
stockholder approval at the 1998 Annual Meeting.

          B.   The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of each calendar
year, beginning with the 1998 calendar year and continuing through calendar year
2001, by an amount equal to one and six-tenths percent (1.6%) of the total
number of shares of Common Stock outstanding on the last trading day of the
immediately preceding calendar year.  No Incentive Options may be granted on the
basis of the additional shares of Common Stock resulting from such annual
increases.

          C.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 1,600,000 shares of Common Stock in the aggregate over the term of the
Plan.

          D.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
(including any options incorporated from the Predecessor Plan) expire or
terminate for any reason prior to exercise in full or (ii) the options are
cancelled in accordance with the cancellation-regrant provisions of

- --------------------
/1/  All share numbers in this Plan reflect (i) the 1-for-3 reverse split of the
Common Stock effected prior to the Plan Effective Date, (ii) the 2-for-1 split
of the Common Stock effected October 27, 1995 and (iii) the 2-for-1 split of the
Common Stock effected on September 25, 1997 through a dividend of one share of
Common Stock distributed on each outstanding share of Common Stock.

                                       4.
<PAGE>
 
Article Two.  Unvested shares issued under the Plan and subsequently cancelled
or repurchased by the Corporation, at the original option exercise or direct
issue price paid per share, pursuant to the Corporation's repurchase rights
under the Plan shall be added back to the number of shares of Common Stock
reserved for issuance under the Plan and shall accordingly be available for
reissuance through one or more subsequent option grants or direct stock
issuances under the Plan.  However, should the exercise price of an option under
the Plan (including any option incorporated from the Predecessor Plan) be paid
with shares of Common Stock or should shares of Common Stock otherwise issuable
under the Plan be withheld by the Corporation in satisfaction of the withholding
taxes incurred in connection with the exercise of an option or the vesting of a
stock issuance under the Plan, then the number of shares of Common Stock
available for issuance under the Plan shall be reduced by the gross number of
shares for which the option is exercised or which vest under the stock issuance,
and not by the net number of shares of Common Stock issued to the holder of such
option or stock issuance.

          E.  Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan, (ii) the number and/or class of securities for which any one
person may be granted options, separately exercisable stock appreciation rights
and direct stock issuances over the term of the Plan, (iii) the number and/or
class of securities for which automatic option grants are to be subsequently
made per Eligible Director under the Automatic Option Grant Program and (iv) the
number and/or class of securities and the exercise price per share in effect
under each outstanding option (including any option incorporated from the
Predecessor Plan) in order to prevent the dilution or enlargement of benefits
thereunder.  The adjustments determined by the Plan Administrator shall be
final, binding and conclusive.

                                       5.

                                 ARTICLE TWO

                     DISCRETIONARY OPTION GRANT PROGRAM
                     ----------------------------------


     I.   OPTION TERMS

          Each granted option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; provided, however, that each such
                                         --------                         
document shall comply with the terms specified below.  Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   Exercise Price.
               -------------- 

          1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date.

          2.   The exercise price shall become immediately due upon exercise
of the option and shall, subject to the provisions of Section I of Article
Five and the documents evidencing the option grant, be payable in one or more
of the forms specified below:

               (i)   cash or check made payable to the Corporation,

               (ii)  shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

               (iii)  to the extent the option is exercised for vested shares,
     through a special sale and remittance procedure pursuant to which the
     Optionee shall concurrently provide irrevocable written instructions to (A)
     a Corporation-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (B) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale transaction.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

                                       6.
<PAGE>
 
          B.   Exercise and Term of Options.  Each option shall be exercisable
               ----------------------------                                   
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option.  However, no option shall have a term in excess of ten
(10) years measured from the option grant date.

          C.   Effect of Termination of Service.
               -------------------------------- 

          1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

               (i)   Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

               (ii)  Any option exercisable in whole or in part by the Optionee
     at the time of death may be subsequently exercised by the personal
     representative of the Optionee's estate or by the person or persons to whom
     the option is transferred pursuant to the Optionee's will or in accordance
     with the laws of descent and distribution.

               (iii) During the applicable post-Service exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service.  Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised.  However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent it is not exercisable for vested shares on
     the date of such cessation of Service.

               (iv)  Should the Optionee's Service be terminated for Misconduct,
     then all outstanding options held by the Optionee shall terminate
     immediately and cease to be outstanding.

          2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

               (i)   extend the period of time for which the option is to remain
     exercisable following the Optionee's cessation of Service from the period
     otherwise in effect for that option to such greater period of time as the
     Plan Administrator shall deem appropriate, but in no event beyond the
     expiration of the option term, and/or

                                       7.
<PAGE>
 
               (ii) permit the option to be exercised, during the applicable
     post-Service exercise period, not only with respect to the number of vested
     shares of Common Stock for which such option is exercisable at the time of
     the Optionee's cessation of Service but also with respect to one or more
     additional installments in which the Optionee would have vested had the
     Optionee continued in Service.

          D.   Stockholder Rights.  The holder of an option shall have no
               ------------------                                        
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   Repurchase Rights.  The Plan Administrator shall have the
               -----------------                                        
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

          F.   Limited Transferability of Options.  During the lifetime of the
               ----------------------------------                             
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death.  However, a Non-Statutory
Option may, in connection with the Optionee's estate plan, be assigned in whole
or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust established exclusively for one or
more such family members.  The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Five shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options when
issued under the Plan shall not be subject to the terms of this Section II.
                            ---                                            

          A.   Eligibility.  Incentive Options may only be granted to Employees.
               -----------                                                      

          B.   Exercise Price.  The exercise price per share shall not be less
               --------------                                                 
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

                                       8.
<PAGE>
 
          C.  Dollar Limitation.  The aggregate Fair Market Value (determined as
              -----------------                                                 
of the respective date or dates of grant) of the Common Stock for which one or
more options granted to any Employee under the Plan (or any other option plan of
the Corporation or any Parent or Subsidiary) may for the first time become
exercisable as Incentive Options during any one calendar year shall not exceed
the sum of One Hundred Thousand Dollars ($100,000).  To the extent the Employee
holds two (2) or more such options which become exercisable for the first time
in the same calendar year, the foregoing limitation on the exercisability of
such options as Incentive Options shall be applied on the basis of the order in
which such options are granted.

          D.   10% Stockholder.  If any Employee to whom an Incentive Option is
               ---------------                                                 
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable for all of the shares of Common Stock at the time subject to
such option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock.  However, an outstanding option shall NOT so accelerate
if and to the extent:  (i) such option is, in connection with the Corporate
Transaction, either to be assumed by the successor corporation (or parent
thereof) or to be replaced with a comparable option to purchase shares of the
capital stock of the successor corporation (or parent thereof), (ii) such option
is to be replaced with a cash incentive program of the successor corporation
which preserves the spread existing on the unvested option shares at the time of
the Corporate Transaction and provides for subsequent payout in accordance with
the same vesting schedule applicable to such option or (iii) the acceleration of
such option is subject to other limitations imposed by the Plan Administrator at
the time of the option grant.  The determination of option comparability under
clause (i) above shall be made by the Plan Administrator, and its determination
shall be final, binding and conclusive.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are to be assigned to the
successor corporation (or parent thereof) in connection with such Corporate
Transaction or (ii) such accelerated vesting is precluded by other limitations
imposed by the Plan Administrator at the time the repurchase right is issued.

          C.   The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration of one or more
outstanding options upon the occurrence of a Corporate Transaction, whether or
not those options are to be assumed or replaced in the Corporate Transaction.

                                       9.
<PAGE>
 
          D.  Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          E.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, provided the aggregate exercise price
                                     --------                             
payable for such securities shall remain the same.  In addition, appropriate
adjustments to reflect the Corporate Transaction shall be made to (i) the class
and number of securities available for issuance over the remaining term of the
Plan and (ii) the maximum number and/or class of securities for which any one
person may be granted stock options, separately exercisable stock appreciation
rights and direct stock issuances in the aggregate over the remaining term of
the Plan.

          F.   Any options which are assumed or replaced in the Corporate
Transaction and do not otherwise accelerate at that time shall automatically
accelerate (and any of the Corporation's outstanding repurchase rights which do
not otherwise terminate at the time of the Corporate Transaction shall
automatically terminate and the shares of Common Stock subject to those
terminated rights shall immediately vest in full) in the event the Optionee's
Service should subsequently terminate by reason of an Involuntary Termination
within eighteen (18) months following the effective date of such Corporate
Transaction.  Any options so accelerated shall remain exercisable for fully-
vested shares until the earlier of (i) the expiration of the option term or (ii)
                        -------                                                 
the expiration of the one (1)-year period measured from the effective date of
the Involuntary Termination.

          G.   The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to (i)  provide for the automatic acceleration of one or more
outstanding options (and the automatic termination of one or more outstanding
repurchase rights with the immediate vesting of the shares of Common Stock
subject to those rights) upon the occurrence of a Change in Control or (ii)
condition any such option acceleration (and the termination of any outstanding
repurchase rights) upon the subsequent Involuntary Termination of the Optionee's
Service within a specified period following the effective date of such Change in
Control.  Any options accelerated in connection with a Change in Control shall
remain fully exercisable until the expiration of the option term.

          H.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded.  To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a Non-
Statutory Option under the Federal tax laws.

                                      10.
<PAGE>
 
          I.  The grant of options under the Discretionary Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new option grant date.

     V.  STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

               (i)   One or more Optionees may be granted the right, exercisable
     upon such terms as the Plan Administrator may establish, to elect between
     the exercise of the underlying option for shares of Common Stock and the
     surrender of that option in exchange for a distribution from the
     Corporation in an amount equal to the excess of (A) the Fair Market Value
     (on the option surrender date) of the number of shares in which the
     Optionee is at the time vested under the surrendered option (or surrendered
     portion thereof) over (B) the aggregate exercise price payable for such
     shares.

               (ii)  No such option surrender shall be effective unless it is
     approved by the Plan Administrator.  If the surrender is so approved, then
     the distribution to which the Optionee shall be entitled may be made in
     shares of Common Stock valued at Fair Market Value on the option surrender
     date, in cash, or partly in shares and partly in cash, as the Plan
     Administrator shall in its sole discretion deem appropriate.

               (iii) If the surrender of an option is rejected by the Plan
     Administrator, then the Optionee shall retain whatever rights the Optionee
     had under the surrendered option (or surrendered portion thereof) on the
     option surrender date and may exercise such rights at any time prior to the
     later of (A)
     -----       

                                      11.
<PAGE>
 
     five (5) business days after the receipt of the rejection notice or (B) the
     last day on which the option is otherwise exercisable in accordance with
     the terms of the documents evidencing such option, but in no event may such
     rights be exercised more than ten (10) years after the option grant date.

          C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

               (i)   One or more Section 16 Insiders may be granted limited
     stock appreciation rights with respect to their outstanding options.

               (ii)  Upon the occurrence of a Hostile Take-Over, each such
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for a
     thirty (30)-day period following such Hostile Take-Over) to surrender each
     such option to the Corporation, to the extent the option is at the time
     exercisable for vested shares of Common Stock.  In return for the
     surrendered option, the Optionee shall receive a cash distribution from the
     Corporation in an amount equal to the excess of (A) the Take-Over Price of
     the shares of Common Stock which are at the time vested under each
     surrendered option (or surrendered portion thereof) over (B) the aggregate
     exercise price payable for such shares.  Such cash distribution shall be
     paid within five (5) days following the option surrender date.

               (iii) The Plan Administrator shall pre-approve, at the time the
     limited right is granted, the subsequent exercise of that right in
     accordance with the terms of the grant and the provisions of this Section
     V.  No additional approval of the Plan Administrator or the Board shall be
     required at the time of the actual option surrender and cash distribution.

               (iv)  The balance of the option (if any) shall continue in full
     force and effect in accordance with the documents evidencing such option.

                                      12.

                           STOCK ISSUANCE PROGRAM
                           ----------------------


     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

          A.   Purchase Price.
               -------------- 

               1.  The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the stock issuance date.

               2.  Subject to the provisions of Section I of Article Five,
shares of Common Stock may be issued under the Stock Issuance Program for one or
both of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

                   (i)   cash or check made payable to the Corporation, or

                   (ii)  past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   Vesting Provisions.
               ------------------ 

               1.  Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

                   (i)   the Service period to be completed by the Participant
     or the performance objectives to be attained,

                   (ii)  the number of installments in which the shares are to
     vest,

                   (iii) the interval or intervals (if any) which are to lapse
     between installments, and

                                      13.
<PAGE>
 
                   (iv)  the effect which death, Permanent Disability or other
     event designated by the Plan Administrator is to have upon the vesting
     schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

          2.       Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to his or her unvested
shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

          3.       The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to him or her under the Stock
Issuance Program, whether or not his or her interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares.

          4.       Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to such surrendered shares.

          5.       The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock (or
other assets attributable thereto) which would otherwise occur upon the non-
completion of the vesting schedule applicable to such shares.  Such waiver shall
result in the immediate vesting of the Participant's interest in the shares of
Common Stock as to which the waiver applies.  Such waiver may be effected at any
time, whether before or after the Participant's cessation of Service or the
attainment or non-attainment of the applicable performance objectives.

                                      14.
<PAGE>
 
     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase rights under the
Stock Issuance Program shall terminate automatically, and all the shares of
Common Stock subject to those terminated rights shall immediately vest in full,
in the event of any Corporate Transaction, except to the extent (i) those
repurchase rights are assigned to the successor corporation (or parent thereof)
in connection with such Corporate Transaction or (ii) such accelerated vesting
is precluded by other limitations imposed in the Stock Issuance Agreement.

          B.   The Plan Administrator shall have the discretion, exercisable
either at the time the unvested shares are issued or at any time while the
Corporation's repurchase right remains outstanding, to provide for the automatic
termination of one or more of those outstanding rights and the immediate vesting
of the shares of Common Stock subject to such rights upon the occurrence of a
Corporate Transaction.

          C.   Any repurchase rights that are assigned in the Corporate
Transaction shall automatically terminate, and all the shares of Common Stock
subject to those terminated rights shall immediately vest in full, in the event
the Optionee's Service should subsequently terminate by reason of an Involuntary
Termination within eighteen (18) months following the effective date of such
Corporate Transaction.

          D.   The Plan Administrator shall have the discretion, exercisable
either at the time the unvested shares are issued or at any time while the
Corporation's repurchase right remains outstanding, to (i) provide for the
automatic termination of one or more of those outstanding rights and the
immediate vesting of the shares subject to such rights upon the occurrence of a
Change in Control or (ii) condition any such accelerated vesting upon the
subsequent Involuntary Termination of the Participant's Service within a
specified period following the effective date of such Change in Control.

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                       AUTOMATIC OPTION GRANT PROGRAM
                       ------------------------------


     I.   OPTION TERMS

          A.   Grant Dates.  Pursuant to the provisions of the February 1, 1996
               -----------                                                     
restatement of this Article Four, option grants shall be made to Eligible
Directors in accordance with the grant date provisions specified below:

               1.  Each individual serving as an Eligible Director on February
1, 1996 was automatically granted on such date a Non-Statutory Option to
purchase 40,000 shares of Common Stock.

               2.  Each individual who first becomes an Eligible Director
after February 1, 1996 shall automatically be granted, on the date such
individual is first elected or appointed as a non-employee Board member, a Non-
Statutory Option to purchase 40,000 shares of Common Stock.

               3.  On the date of each Annual Stockholders Meeting, beginning
with the 1997 Annual Meeting, each individual who is to continue as an
Eligible Director shall automatically be granted, whether or not he or she is
standing for re-election as a Board member at that Annual Meeting, a Non-
Statutory Option to purchase an additional 4,000 shares of Common Stock,
provided such individual has not received an option grant pursuant to this
Automatic Option Grant Program within six (6) months prior to the date of such
Annual Meeting. There shall be no limit on the number of such 4,000-share
option grants any one Eligible Director may receive over his or her period of
Board service. The number of shares for which the automatic option grants are
to be made to each newly-elected or continuing Eligible Director shall be
subject to periodic adjustment pursuant to the applicable provisions of
Section V.D. of Article One.

               Stockholder approval of this 1998 Restatement at the 1998 Annual
Stockholders Meeting will constitute pre-approval of each option subsequently
granted on or after the date of such Annual Meeting pursuant to the express
terms of this Automatic Option Grant Program and the subsequent exercise of that
option in accordance with its terms.

          B.   Exercise Price.
               -------------- 

               1.  The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.

                                      16.
<PAGE>
 
               2.  The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   Option Term.  Each option shall have a term of ten (10) years
               -----------                                                  
measured from the option grant date.

          D.   Exercise and Vesting of Options.  Each option shall be
               -------------------------------                       
immediately exercisable for any or all of the option shares.  However, any
shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's cessation
of Board service prior to vesting in those shares.  The shares subject to each
option, whether the initial 40,000-share grant or any annual 4,000-share grant,
shall vest, and the Corporation's repurchase right with respect to those shares
shall lapse, in a series of eight (8) successive equal quarterly installments
upon the Optionee's completion of each three (3) months of continued service as
a Board member over the twenty-four (24)-month period measured from the option
grant date.

          E.   Effect of Termination of Board Service.  The following provisions
               --------------------------------------                           
shall govern the exercise of any options held by the Optionee at the time the
Optionee ceases to serve as a Board member:

               (i)   The Optionee (or, in the event of Optionee's death, the
     personal representative of the Optionee's estate or the person or persons
     to whom the option is transferred pursuant to the Optionee's will or in
     accordance with the laws of descent and distribution) shall have a twelve
     (12)-month period following the date of such cessation of Board service in
     which to exercise each such option.

               (ii)  During the twelve (12)-month exercise period, the option
     may not be exercised in the aggregate for more than the number of vested
     shares of Common Stock for which the option is exercisable at the time of
     the Optionee's cessation of Board service.

               (iii) Should the Optionee cease to serve as a Board member by
     reason of death or Permanent Disability, then all shares at the time
     subject to the option shall immediately vest so that such option may,
     during the twelve (12)-month exercise period following such cessation of
     Board service, be exercised for all or any portion of such shares as fully-
     vested shares of Common Stock.

               (iv)  In no event shall the option remain exercisable after the
     expiration of the option term.  Upon the expiration of the twelve (12)-
     month exercise period or (if earlier) upon the expiration of the option
     term, the option

                                      17.
<PAGE>
 
     shall terminate and cease to be outstanding for any vested shares for which
     the option has not been exercised.  However, the option shall, immediately
     upon the Optionee's cessation of Board service, terminate and cease to be
     outstanding to the extent it is not exercisable for vested shares at that
     time.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Corporate Transaction, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of such shares as fully-
vested shares of Common Stock.  Immediately following the consummation of the
Corporate Transaction, each automatic option grant shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          B.   In connection with any Change in Control, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Change in Control, become fully exercisable
for all of the shares of Common Stock at the time subject to such option and may
be exercised for all or any portion of such shares as fully-vested shares of
Common Stock.  Each such option shall remain exercisable for the fully-vested
option shares until the expiration or sooner termination of the option term or
the surrender of the option in connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
automatic option held by him or her.  The Optionee shall in return be entitled
to a cash distribution from the Corporation in an amount equal to the excess of
(i) the Take-Over Price of the shares of Common Stock at the time subject to the
surrendered option (whether or not the Optionee is otherwise at the time vested
in those shares) over (ii) the aggregate exercise price payable for such shares.
Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation.  Stockholder approval of this 1998
Restatement at the 1998 Annual Meeting shall constitute pre-approval of each
option granted with such a surrender right under this Automatic Option Grant
Program on or after the date of that Annual Meeting and the subsequent exercise
of such right in accordance with the terms and provisions of this Section II.C.
No additional approval or consent of the Plan Administrator or the Board shall
be required at the time of the actual option surrender and cash distribution.

          D.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

                                      18.

     III. REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

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


     I.   FINANCING

          A.   The Plan Administrator may permit any Optionee or Participant to
pay the option exercise price under the Discretionary Option Grant Program or
the purchase price of shares issued under the Stock Issuance Program by
delivering a promissory note payable in one or more installments.  The terms of
any such promissory note (including the interest rate and the terms of
repayment) shall be established by the Plan Administrator in its sole
discretion.  Promissory notes may be authorized with or without security or
collateral.  In all events, the maximum credit available to the Optionee or
Participant may not exceed the sum of (i) the aggregate option exercise price or
purchase price payable for the purchased shares plus (ii) any Federal, state and
local income and employment tax liability incurred by the Optionee or the
Participant in connection with the option exercise or share purchase.

          B.   The Plan Administrator may, in its discretion, determine that one
or more such promissory notes shall be subject to forgiveness by the Corporation
in whole or in part upon such terms as the Plan Administrator may deem
appropriate.

     II.  TAX WITHHOLDING

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or stock appreciation rights or upon the issuance
or vesting of such shares under the Plan shall be subject to the satisfaction of
all applicable Federal, state and local income and employment tax withholding
requirements.

          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their shares.  Such right
may be provided to any such holder in either or both of the following formats:

               (i) Stock Withholding:  The election to have the Corporation
                   -----------------                                       
     withhold, from the shares of Common Stock otherwise issuable upon the
     exercise of such Non-Statutory Option or the vesting of such shares, a
     portion of those shares with an aggregate Fair Market Value equal to the
     percentage of the Taxes (not to exceed one hundred percent (100%))
     designated by the holder.

                                      20.

               (ii) Stock Delivery:  The election to deliver to the Corporation,
                    --------------                                              
     at the time the Non-Statutory Option is exercised or the shares vest, one
     or more shares of Common Stock previously acquired by such holder (other
     than in connection with the option exercise or share vesting triggering the
     Taxes) with an aggregate Fair Market Value equal to the percentage of the
     Taxes (not to exceed one hundred percent (100%)) designated by the holder.

     III.  EFFECTIVE DATE AND TERM OF THE PLAN

           A.   The Plan became effective on the date on which the Underwriting
Agreement was executed and the initial public offering price of the Common Stock
was established.  The Plan serves as the successor to the Predecessor Plan, and
no further option grants shall be made under the Predecessor Plan after the Plan
Effective Date.  All options outstanding under the Predecessor Plan on the Plan
Effective Date have been incorporated into the Plan and treated as outstanding
options under the Plan.  However, each outstanding option so incorporated shall
continue to be governed solely by the terms of the documents evidencing such
option, and no provision of the Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of Common Stock.

           B.   The Plan was amended and restated by the Board, effective
February 1, 1996 (the "February 1996 Restatement") to effect the following
revisions: (i) increase the maximum number of shares of Common Stock authorized
for issuance over the term of the Plan by an additional 1,600,000 shares to
5,535,888 shares and (ii) enhance the benefit and eligibility provisions of the
Automatic Option Grant Program in order to (A) effect an automatic option grant
for 40,000 shares of Common Stock on February 1, 1996 to each individual serving
as a non-employee Board member at that time, (B) increase the number of shares
for which an initial option grant is to be made under the Automatic Option Grant
Program to each newly-elected non-employee Board member to 40,000 shares, (C)
authorize a series of automatic option grants to be made annually to each non-
employee Board member, in the amount of 4,000 shares per annual grant, over that
individual's period of continued service as a Board member and (D) allow non-
employee Board members who joined the Board prior to the implementation of the
Plan to qualify for such annual option grants.  The February 1996 Restatement
became effective immediately upon adoption by the Board and was approved by the
Corporation's stockholders at the 1996 Annual Meeting.  All option grants made
under the Plan prior to the February 1996 Restatement shall remain outstanding
in accordance with the terms and conditions of the respective instruments
evidencing those options, and nothing in the February 1996 Restatement shall be
deemed to modify or in any way affect those outstanding options.

           C.   In April 1997, the Board further amended and restated the Plan
(the "April 1997 Restatement") to effect the following revisions: (i) increase
the number of shares of Common Stock reserved for issuance over the term of the
Plan by an additional 3,000,000 shares to 8,535,888 shares, (ii) implement an
automatic share increase feature pursuant to which the number of shares
available for issuance under the 1995 Plan shall automatically increase on the

                                      21.

first trading day of each calendar year, beginning with the 1998 calendar year
and continuing through calendar year 2001, by an amount equal to one and six
tenths percent (1.6%) of the total number of shares of Common Stock outstanding
on the last trading day of the immediately preceding calendar year, (iii) render
the non-employee Board members eligible to receive option grants under the
Discretionary Option Grant and Stock Issuance Programs, (iv) allow unvested
shares issued under the Plan and subsequently repurchased by the Corporation at
the option exercise or direct issue price paid per share to be reissued under
the Plan, (v) remove certain restrictions on the eligibility of non-employee
Board members to serve as Plan Administrator and (vi) effect a series of
additional changes to the provisions of the Plan (including the stockholder
approval requirements) in order to take advantage of the recent amendments to
Rule 16b-3 of the Securities and Exchange Commission which exempts certain
officer and director transactions under the Plan from the short-swing liability
provisions of the federal securities laws.  The stockholders approved the April
1997 Restatement at the 1997 Annual Meeting.  All option grants made under the
Plan prior to the April 1997 Restatement shall remain outstanding in accordance
with the terms and conditions of the respective instruments evidencing those
options, and nothing in the April 1997 Restatement shall be deemed to modify or
in any way affect those outstanding options.

          D.   On March 11, 1998 the Board further amended and restated the Plan
(the "1998 Restatement") to increase the number of shares of Common Stock
reserved for issuance over the term of the Plan by an additional 3,500,000
shares to 12,719,625 shares of Common Stock.  The 1998 Restatement is subject to
stockholder approval at the 1998 Annual Meeting, and no option grants made on
the basis of the 3,500,000-share increase under the 1998 Restatement shall
become exercisable in whole or in part unless and until the 1998 Restatement is
approved by the stockholders.  Should such stockholder approval not be obtained,
then each option grant made pursuant to the 3,500,000-share increase shall
terminate and cease to remain outstanding without ever becoming exercisable for
those shares, and no additional option grants shall be made on the basis of that
share increase.  All option grants and stock issuances made prior to the 1998
Restatement shall remain outstanding in accordance with the terms and conditions
of the respective instruments evidencing those options or issuances, and nothing
in the 1998 Restatement shall be deemed to modify or in any way affect those
outstanding options or issuances.  Subject to the foregoing limitations, the
Plan Administrator may make option grants and direct stock issuances under the
Plan at any time before the date fixed herein for the termination of the Plan.

          E.   The option/vesting acceleration provisions of Article Two
relating to Corporate Transactions and Changes in Control may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise provide for such acceleration.

                                      22.

          F.   The Plan shall terminate upon the earliest of (i) January 10,
                                                 --------                   
2005, (ii) the date on which all shares available for issuance under the Plan
shall have been issued pursuant to the exercise of the options or the issuance
of shares (whether vested or unvested) under the Plan or (iii) the termination
of all outstanding options in connection with a Corporate Transaction.  Upon
such Plan termination, all options and unvested stock issuances outstanding on
such date shall thereafter continue to have force and effect in accordance with
the provisions of the documents evidencing such options or issuances.

     IV.  AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, (i) no such
amendment or modification shall adversely affect the rights and obligations with
respect to options, stock appreciation rights or unvested stock issuances at the
time outstanding under the Plan unless the Optionee or the Participant consents
to such amendment or modification, and (ii) any amendment made to the Automatic
Option Grant Program (or any options outstanding thereunder) shall be in
compliance with the limitations of that program.  In addition, certain
amendments may require stockholder approval pursuant to applicable laws or
regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant Program and shares of Common Stock may be issued
under the Stock Issuance Program that are in each instance in excess of the
number of shares then available for issuance under the Plan, provided any excess
shares actually issued under those programs are held in escrow until there is
obtained stockholder approval of an amendment sufficiently increasing the number
of shares of Common Stock available for issuance under the Plan.  If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess grants or issuances are made, then (i) any unexercised
options granted on the basis of such excess shares shall terminate and cease to
be outstanding and (ii) the Corporation shall promptly refund to the Optionees
and the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VI.  REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any option or
stock appreciation right under the Plan and the issuance of any shares of Common
Stock (i) upon the exercise of any option or stock appreciation right or (ii)
under the Stock Issuance Program shall

                                      23.
<PAGE>
 
be subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the
options and stock appreciation rights granted under it and the shares of Common
Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

     VII. NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                        EMPLOYEE STOCK PURCHASE PLAN

          (As Amended and Restated Effective as of March 11, 1998)

       I.   PURPOSE OF THE PLAN

            This Employee Stock Purchase Plan is intended to promote the
interests of P- COM, Inc. by providing eligible employees with the opportunity
to acquire a proprietary interest in the Corporation through participation in a
payroll-deduction based employee stock purchase plan designed to qualify under
Section 423 of the Code.

            Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

            All share numbers in this document reflect (i) the 1-for-3
reverse split of the Common Stock effected after the Board's adoption of the
Plan but prior to the Effective Time, (ii) the 2-for-1 forward split of the
Common Stock effected on October 27, 1995, and (iii) the 1-for-1 dividend of the
Common Stock effected on September 25, 1997.

      II.   ADMINISTRATION OF THE PLAN

            The Plan Administrator shall have full authority to interpret
and construe any provision of the Plan and to adopt such rules and regulations
for administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423. Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III.   STOCK SUBJECT TO PLAN

            A. The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed One Million One
Hundred Fifty Thousand (1,150,000) shares. Such authorized share reserve is
comprised of (i) the Four Hundred Thousand (400,000) shares initially authorized
for issuance under the Plan, (ii) an additional increase of Two Hundred Thousand
(200,000) shares of Common Stock authorized for issuance by the Board on
February 1, 1996 and approved by the Corporation's stockholders at the 1996
Annual Meeting, (iii) a further increase of Three Hundred Thousand (300,000)
shares authorized for issuance by the Board in April 1997, and approved by the
stockholders at the 1997 Annual Meeting, and (iv) an additional increase of

            B. In the event any change is made to the Common Stock by
reason of any stock split, stock dividend, recapitalization, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and class of securities
issuable under the Plan, (ii) the maximum number and class of securities
purchasable per Participant on any one Semi-Annual Purchase Date and (iii) the
number and class of securities and the price per share in effect under each
outstanding purchase right in order to prevent the dilution or enlargement of
benefits thereunder.

      IV.   OFFERING PERIODS

            A. Shares of Common Stock shall be offered for purchase under
the Plan through a series of successive offering periods until such time as (i)
the maximum number of shares of Common Stock available for issuance under the
Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated.

            B. Each offering period shall have a maximum duration of
twenty-four (24) months. The duration of each offering period shall be
designated by the Plan Administrator prior to its start date. The initial
offering period commenced at the Effective Time and shall terminate on the last
business day in January 1997. The next offering period shall commence on the
first business day in February 1997, and subsequent offering periods shall
commence as designated by the Plan Administrator.

       V.   ELIGIBILITY

            A. Each Eligible Employee shall be eligible to participate in the
Plan in accordance with the following provisions:

               (i)   An individual who is an Eligible Employee on the start
         date of any offering period shall be eligible to commence
         participation in that offering period on such start date or on any
         subsequent Semi-Annual Entry Date within that offering period on which
         he/she remains an Eligible Employee.

               (ii)  An individual who first becomes an Eligible Employee after
         the start date of any offering period may enter that offering period on
         the first SemiAnnual Entry Date on which he/she is an Eligible Employee
         or on any subsequent SemiAnnual Entry Date within that offering period
         on which he/she remains an Eligible Employee.

            B. To participate in the Plan for a particular offering period,
the Eligible Employee must complete the enrollment forms prescribed by the
Plan Administrator (including a stock purchase agreement and a payroll
deduction authorization form) and file such forms with the Plan Administrator
(or its designate) on or before his/her scheduled Entry Date.

      VI.   PAYROLL DEDUCTIONS

            A. The payroll deduction authorized by the Participant for
purposes of acquiring shares of Common Stock under the Plan may be any multiple
of one percent (1%) of the Base Salary paid to the Participant during each
Semi-Annual Period of Participation within the offering period, up to a maximum
of fifteen percent (15%). The deduction rate so authorized shall continue in
effect for the remainder of the offering period, except to the extent such rate
is changed in accordance with the following guidelines:

               (i)   The Participant may, at any time during a Semi-
         Annual Period of Participation, reduce his or her rate of payroll
         deduction to become effective as soon as possible after filing the
         appropriate form with the Plan Administrator. The Participant may not,
         however, effect more than one (1) such reduction per Semi-Annual Period
         of Participation.

               (ii)  The Participant may, prior to the commencement of any new
         Semi-Annual Period of Participation within the offering period,
         increase the rate of his or her payroll deduction by filing the
         appropriate form with the Plan Administrator. The new rate (which may
         not exceed the fifteen percent (15%) maximum) shall become effective
         as of the first day of the first SemiAnnual Period of Participation
         following the filing of such form.

            B. Payroll deductions shall begin on the first pay day following
the Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of the offering period. The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account. The amounts collected from the Participant shall not be held in
any segregated account or trust fund and may be commingled with the general
assets of the Corporation and used for general corporate purposes.

            C. Payroll deductions shall automatically cease upon the
termination of the Participant's purchase right in accordance with the
provisions of Section VII below.

            D. The Participant's acquisition of Common Stock under the
Plan on any Semi-Annual Purchase Date shall neither limit nor require the
Participant's acquisition of Common Stock on any subsequent Semi-Annual Purchase
Date, whether within the same or a different offering period.

                                       3.

     VII.   PURCHASE RIGHTS

            A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a
               -----------------------
separate purchase right for each offering period in which he or she
participates. The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive semi-annual
installments over the remainder of such offering period, upon the terms set
forth below. The Participant shall execute a stock purchase agreement embodying
such terms and such other provisions (not inconsistent with the Plan) as the
Plan Administrator may deem advisable.

            Under no circumstances shall purchase rights be granted under
the Plan to any Eligible Employee if such individual would, immediately after
the grant, own (within the meaning of Code Section 424(d)) or hold outstanding
options or other rights to purchase, stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Corporation or any Corporate Affiliate.

            B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall
               ------------------------------
be automatically exercised in successive semi-annual installments on each
Semi-Annual Purchase Date in an offering period, and shares of Common Stock
shall accordingly be purchased on behalf of each Participant (other than
Participants whose payroll deductions have previously been refunded in
accordance with the Termination of Purchase Right provisions below) on each such
date. The purchase shall be effected by applying the Participant's payroll
deductions for the Semi-Annual Period of Participation ending on such
Semi-Annual Purchase Date (together with any carryover deductions from the
preceding Semi-Annual Period of Participation) to the purchase of whole shares
of Common Stock (subject to the limitation on the maximum number of shares
purchasable per Participant on any one Semi-Annual Purchase Date) at the
purchase price in effect for the Participant for that Semi-Annual Purchase Date.

            C. PURCHASE PRICE. The purchase price per share at which
               --------------
Common Stock will be purchased on the Participant's behalf on each Semi-Annual
Purchase Date within the offering period shall be equal to eighty-five percent
(85%) of the lower of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Semi-Annual Purchase Date. However, for each
Participant whose Entry Date is other than the start date of the offering
period, the clause (i) amount shall in no event be less than the Fair Market
Value per share of Common Stock on the start date of that offering period.

            D. NUMBER OF PURCHASABLE SHARES. The number of shares
               ----------------------------
purchasable by a Participant on each Semi-Annual Purchase Date during the
offering period shall be the number of whole shares obtained by dividing the
amount collected from the Participant through payroll deductions during the
Semi-Annual Period of Participation ending with that Semi-Annual Purchase Date
(together with any carryover deductions from the preceding Semi-Annual Period of
Participation) by the purchase price in effect for that Semi-Annual Purchase
Date. However,

                                       4.
<PAGE>
 

the maximum number of shares of Common Stock purchasable per Participant on any
one Semi-Annual Purchase Date shall not exceed Two Thousand (2,000) shares,
subject to periodic adjustments in the event of certain changes in the
Corporation's capitalization.

          E.     EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied
                 -------------------------                                     
to the  purchase of shares of Common Stock on any Semi-Annual Purchase Date
because they are not sufficient to purchase a whole share of Common Stock shall
be held for the purchase of Common Stock on the next Semi-Annual Purchase Date.
However, any payroll deductions not applied to the purchase of Common Stock by
reason of the limitation on the maximum number of shares purchasable by the
Participant on the Semi-Annual Purchase Date shall be promptly refunded.

          F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
               -----------------------------                                 
govern the termination of outstanding purchase rights:

               (i)   A Participant may, at any time prior to the next Semi-
     Annual Purchase Date in an offering period, terminate his or her
     outstanding purchase right under the offering period by filing the
     appropriate form with the Plan Administrator (or its designate), and no
     further payroll deductions shall be collected from the Participant with
     respect to the terminated purchase right. Any payroll deductions
     collected during the Semi-Annual Period of Participation in which such
     termination occurs shall, at the Participant's election, be immediately
     refunded or held for the purchase of shares on the next Semi-Annual
     Purchase Date. If no such election is made at the time such purchase
     right is terminated, then the payroll deductions collected with respect
     to the terminated right shall be refunded as soon as possible.

               (ii)  The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the offering
     period for which the terminated purchase right was granted. To resume
     participation in any subsequent offering period, such individual must re-
     enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before the date he or she is first eligible to
     join the new offering period.

               (iii) Should the Participant cease to remain an Eligible
     Employee for any reason (including death, disability or change in status)
     while his or her purchase right remains outstanding, then that purchase
     right shall immediately terminate, and all of the Participant's payroll
     deductions for the Semi-Annual Period of Participation in which such
     cessation of Eligible Employee status occurs shall be immediately refunded.

          G.  CORPORATE TRANSACTION.  In the event of a Corporate Transaction
              ---------------------                                          
during the offering period, each outstanding purchase right shall automatically
be exercised, immediately prior to the effective date of such Corporate
Transaction, by applying the payroll deductions of

                                     5.
<PAGE>
 
each Participant for the Semi-Annual Period of Participation in which such
Corporate Transaction occurs to the purchase of whole shares of Common Stock at
a purchase price per share equal to eighty-five percent (85%) of the lower of
                                                                     -----   
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into the offering period in which such Corporate Transaction occurs or (ii)
the Fair Market Value per share of Common Stock immediately prior to the
effective date of such Corporate Transaction.  However, the applicable share
limitations per Participant shall continue to apply to any such purchase, and
the clause (i) amount above shall not, for any Participant whose Entry Date for
the offering period is other than the start date of that offering period, be
less than the Fair Market Value per share of Common Stock on such start date.

          The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

          H.  PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
              ----------------------------                                    
of Common Stock which are to be purchased pursuant to outstanding purchase
rights on any particular date exceed the number of shares then available for
issuance under the Plan, the Plan Administrator shall make a pro-rata allocation
of the available shares on a uniform and nondiscriminatory basis, and the
payroll deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

          I.  ASSIGNABILITY.  During the Participant's lifetime, the purchase
              -------------                                                  
right shall be exercisable only by the Participant and shall not be assignable
or transferable by the Participant.

          J.  STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
              ------------------                                          
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

     VIII.  ACCRUAL LIMITATIONS

          A.  No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right outstanding under this Plan and
(ii) similar rights accrued under other employee stock purchase plans (within
the meaning of Code Section 423) of the Corporation or any Corporate Affiliate,

                                      6.
<PAGE>
 
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value of such stock on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

          B.  For purposes of applying such accrual limitations, the following
provisions shall be in effect:

               (i)  The right to acquire Common Stock under each purchase right
     shall accrue on each Semi-Annual Purchase Date for which the right remains
     outstanding.

               (ii) No right to acquire Common Stock under any outstanding
     purchase right shall accrue to the extent the Participant has already
     accrued in the same calendar year the right to acquire Common Stock under
     one (1) or more other purchase rights at a rate equal to Twenty-Five
     Thousand Dollars ($25,000) worth of Common Stock (determined on the basis
     of the Fair Market Value of such stock on the date or dates of grant) for
     each calendar year such rights were at any time outstanding.

          C.  If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Semi-Annual Period of
Participation, then the payroll deductions which the Participant made during
that Semi-Annual Period of Participation with respect to such purchase right
shall be promptly refunded.

          D.  In the event there is any conflict between the provisions of this
article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this article shall be controlling.

     IX.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.  The Plan was adopted by the Board in January 1995 and approved by
the stockholders in February 1995, and the Plan became effective at the

approved by the Corporation's stockholders at the 1996 Annual Meeting.  The
300,000-share increase to the share reserve available for issuance under the
Plan was authorized by the Board in April 1997, and approved by the stockholders
at the 1997 Annual Meeting.  On March 11, 1998, the Board authorized an
additional increase of 250,000 shares in the reserve available for issuance
under the Plan.  The March 11, 1998, share increase is subject to approval by
the Corporation's stockholders at the 1998 Annual Meeting.  Should such
stockholder approval not be obtained, then the 250,000-share increase will not
be

                                      7.
<PAGE>
 
implemented, and any purchase rights granted on the basis of the 250,000-share
increase to the Plan will immediately terminate.  No additional purchase rights
will be granted on the basis of such share increase, and the Plan will terminate
once the existing share reserve has been issued.

          B.  Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in January 2005, (ii) the date on
         --------                                                               
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction.

     X.  AMENDMENT OF THE PLAN

          A.   The Board may alter, amend, suspend or discontinue the Plan
following the close of any Semi-Annual Period of Participation.  However, the
Board may not, without the approval of the Corporation's stockholders, (i)
materially increase the number of shares issuable under the Plan or the maximum
number of shares purchasable per Participant on any one Semi-Annual Purchase
Date, except for permissible adjustments in the event of certain changes in the
