        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAWS OF
ANY STATE. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND

FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED

SECURITIES LAWS.

                           REPEATER TECHNOLOGIES, INC.

                       FORM OF WARRANT FOR THE PURCHASE OF
                       SHARES OF SERIES EE PREFERRED STOCK

No. WEE-<<WarrantNumber>>                                       __________, 2000

        FOR VALUE RECEIVED, REPEATER TECHNOLOGIES, INC., a Delaware corporation
(the "Company"), with its principal office at 1150 Morse Avenue, Sunnyvale, CA
94089-1605, hereby certifies that <<NAME>> or its assigns (the "Holder") is
entitled, subject to the provisions of this Warrant, to purchase from the
Company, at any time prior to the Expiration Date (as defined in Section 11
below), the number of fully paid and nonassessable shares of Series EE Preferred
Stock of the Company equal to twenty percent (20%) of
<<AmountSpelledOut>>Dollars ($<<Amount>>.00) divided by the Conversion Price, at
an exercise price per share equal to eight dollars ($8.00) (the "Exercise
Price"). The initial "Conversion Price" per share shall be $8.00, or, if the
Company has consummated a Qualified Public Offering (as defined in the Company's
Certificate of Incorporation, as may be amended from time to time), the lesser
of $8.00 or the initial "Price to Public" specified in the final prospectus
related thereto. The term "Series EE Preferred" shall mean the aforementioned
Series EE Preferred Stock of the Company or any other equity securities that may
be issued by the Company in addition thereto or in substitution therefor as
provided herein.

        The number of shares of Series EE Preferred to be received upon the
exercise of this Warrant and the price to be paid for a share of Series EE
Preferred are subject to adjustment from time to time as hereinafter set forth.
The shares of Series EE Preferred deliverable upon such exercise, as adjusted
from time to time, are hereinafter sometimes referred to as "Warrant Shares."

SECTION 1. EXERCISE OF WARRANT. This Warrant may be exercised in whole or in
part on any business day prior to the Expiration Date by presentation and
surrender to the Company at its principal office at the address set forth in the
initial paragraph hereof (or at such other address as the Company may hereafter
notify the Holder in writing) with the Purchase Form annexed hereto duly
executed and accompanied by proper payment of the Exercise Price in lawful money
of the United States of America in the form of a check, subject to collection,
for the number of Warrant Shares specified in the Purchase Form. If this Warrant
should be

                                       1
<PAGE>   2
exercised in part only, the Company shall, upon surrender of this Warrant,
execute and deliver a new Warrant evidencing the rights of the Holder thereof to
purchase the balance of the Warrant Shares purchasable hereunder. Upon receipt
by the Company of this Warrant and such Purchase Form, together with proper
payment of the Exercise Price, at such office, the Holder shall be deemed to be
the holder of record of the Warrant Shares, notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such Warrant Shares shall not then be actually delivered to the
Holder.

        SECTION 2. NET ISSUE EXERCISE. Notwithstanding any provisions herein to
the contrary, in lieu of exercising this Warrant for cash, the Holder may elect
to receive shares equal to the value (as determined below) of this Warrant (or
the portion thereof being canceled) by surrender of this Warrant at the
principal office of the Company together with notice of such election in which
event the Company shall issue to the Holder a number of shares of Series EE
Preferred computed using the following formula:

                                  X = Y (A - B)
                                      --------
                                         A

                Where   X = the number of shares of Series EE Preferred to be
                        issued to the Holder

                        Y = the number of shares of Series EE Preferred
                        purchasable under the Warrant or, if only a portion of
                        the Warrant is being exercised, the number of shares
                        purchased under the Warrant being canceled (at the date
                        of such calculation)

                        A = the fair market value of one share of the Series EE
                        Preferred (at the date of such calculation)

                        B = Exercise Price (as adjusted to the date of such
                        calculation)

                        For purposes of the above calculation, the fair market
                        value of one share of Series EE Preferred shall be
                        determined by the Company's Board of Directors in good
                        faith; provided, however, that in the event that the
                        warrant is exercised concurrent with an initial public
                        offering of the Company's Common Stock in which the
                        Series EE Preferred is converted to Common Stock, then
                        the price to the public of the Common Stock in such
                        offering shall be used to determine the fair market
                        value and, provided further, that in the event that this
                        warrant becomes exercisable for Common Stock and the
                        Company's Common Stock is publicly traded, the closing
                        price of the Company's stock in the principal market or
                        exchange on which is it traded on the date of exercise
                        (or if not traded on such date, the most recent date on
                        which it was traded) shall be used to determine the fair
                        market value.

        SECTION 3. ISSUANCE OF NEW WARRANT. In the event of any exercise of the
rights represented by this Warrant, certificates for the Warrant Shares so
purchased shall be

                                       2
<PAGE>   3

delivered to the holder hereof as soon as practicable and, unless this
Warrant has been fully exercised or has expired, a new Warrant representing the
portion of the Warrant Shares, if any, with respect to which this Warrant shall
not then have been exercised shall also be issued to the holder hereof within a
reasonable time. Such exercise shall be deemed to have been made immediately
prior to the close of business on the date of surrender of this Warrant.

        SECTION 4. RESERVATION OF SHARES. The Company hereby agrees that at all
times there shall be reserved for issuance and delivery upon exercise of this
Warrant (i) all shares of Series EE Preferred Stock issuable upon exercise of
this Warrant and (ii) all shares of Common Stock issuable upon the conversion of
such shares of Series EE Preferred Stock. All shares of such Series EE Preferred
Stock shall be duly authorized and, when issued upon such exercise in accordance
with the terms of this Warrant, shall be validly issued, fully paid and
nonassessable.

        SECTION 5. FRACTIONAL INTEREST. The Company will not issue a fractional
share of Series EE Preferred upon exercise of this Warrant. Instead, the Company
will deliver its check for the current fair market value of the fractional
share, as determined in good faith by the Board of Directors of the Company.

        SECTION 6. ASSIGNMENT OR LOSS OF WARRANT.

               (a) Except as provided in Section 10, the Holder of this Warrant
shall be entitled, without obtaining the consent of the Company, to assign its
interest in this Warrant in whole or in part to any person or persons. Subject
to the provisions of Section 10, upon surrender of this Warrant to the Company
or at the office of its stock transfer agent or warrant agent, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant or Warrants in the name of the assignee or assignees named in such
instrument of assignment and, if the Holders entire interest is not being
assigned, in the name of the Holder, and this Warrant shall promptly be
canceled.

               (b) Upon receipt of evidence satisfactory to the Company of the
loss, theft, destruction or mutilation of this Warrant, and (in the case of
loss, theft or destruction) of indemnification satisfactory to the Company, and
upon surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver a new Warrant of like tenor and date.

        SECTION 7. RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof,
be entitled to any rights of a shareholder in the Company, either at law or
equity, and the rights of the Holder are limited to those expressed in this
Warrant. Nothing contained in this Warrant shall be construed as conferring upon
the Holder hereof the right to vote or to consent or to receive notice as a
shareholder of the Company on any matters or with respect to any rights
whatsoever as a shareholder of the Company. No dividends or interest shall be
payable or accrued in respect of this Warrant or the interest represented hereby
or the Warrant Shares purchasable hereunder until, and only to the extent that,
this Warrant shall have been exercised in accordance with its terms.

                                       3
<PAGE>   4

        SECTION 8. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The number
and kind of securities purchasable upon the exercise of the Warrant and the
Exercise Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

               (a) RECLASSIFICATION OF OUTSTANDING SECURITIES. In case of any
reclassification, change or conversion of securities of the class issuable upon
exercise of this Warrant (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination), the Company shall execute a new Warrant (in form and substance
reasonably satisfactory to the Holder of this Warrant) providing that the Holder
of this Warrant shall have the right to exercise such new Warrant and upon such
exercise to receive, in lieu of each share of Series EE Preferred theretofore
issuable upon exercise of this Warrant, the kind and amount of shares of stock,
other securities, money and property receivable upon such reclassification or
change by a holder of one share of Series EE Preferred. Such new Warrant shall
provide for adjustments that shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section 8. The provisions of this
subsection (a) shall similarly apply to successive reclassification or changes.

               (b) SUBDIVISIONS OR COMBINATION OF SHARES. If the Company at any
time while this Warrant remains outstanding and unexpired shall subdivide or
combine its Series EE Preferred, the Exercise Price and the number of Warrant
Shares issuable upon exercise hereof shall be proportionately adjusted.

               (c) STOCK DIVIDENDS. If the Company at any time while this
Warrant is outstanding and unexpired shall pay a dividend payable in shares of
Series EE Preferred Stock (except any distribution specifically provided for in
the foregoing subsections (a) and (b)), then the Exercise Price shall be
adjusted, from and after the date of determination of shareholders entitled to
receive such dividend or distribution, to that price determined by multiplying
the Exercise Price in effect immediately prior to such date of determination by
a fraction (a) the numerator of which shall be the total number of shares of
Series EE Preferred Stock outstanding immediately prior to such dividend or
distribution, and (b) the denominator of which shall be the total number of
shares of Series EE Preferred Stock outstanding immediately after such dividend
or distribution and the number of Warrant Shares subject to this Warrant shall
be proportionately adjusted.

               (d) NOTICE OF RECORD DATE. In the event of any taking by the
Company of a record of its shareholders for the purpose of determining
shareholders who are entitled to receive payment of any dividend (other than a
cash dividend) or other distribution, any right to subscribe for, purchase or
otherwise acquire any share of any class or any other securities or property, or
to receive any other right, or for the purpose of determining shareholders who
are entitled to vote in connection with any proposed merger or consolidation of
the Company with or into any other corporation, or any proposed sale, lease or
conveyance of all or substantially all of the assets of the Company, or any
proposed liquidation, dissolution or winding up of the Company, the Company
shall mail to the Holder of this Warrant, at least ten days prior to the date
specified therein, a notice specifying the date on which any such record is to
be taken for the purpose of such dividend, distribution or right, and the amount
and character of such dividend, distribution or right.

                                       4
<PAGE>   5

               (e) NO ADJUSTMENT UPON EXERCISE OF WARRANTS. No adjustments shall
be made under any Section herein in connection with the issuance of Warrant
Shares upon exercise of the Warrants.

        SECTION 9. OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be
adjusted as required by the provisions of Section 8, the Company shall deliver
an officer's certificate showing the adjusted Exercise Price determined as
herein provided, setting forth in reasonable detail the facts requiring such
adjustment and the manner of computing such adjustment. Each such officer's
certificate shall be signed by the chairman, president or chief financial
officer of the Company.

        SECTION 10. TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933. This
Warrant may not be exercised and neither this Warrant nor any of the Warrant
Shares, nor any interest in either, may be sold, assigned, pledged,
hypothecated, encumbered or in any other manner transferred or disposed of, in
whole or in part, except in compliance with applicable United States federal and
state securities or Blue Sky laws and the terms and conditions hereof. Each
Warrant shall bear a legend in substantially the same form as the legend set
forth on the first page of this Warrant. Each certificate for Warrant Shares
issued upon exercise of this Warrant, unless at the time of exercise such
Warrant Shares are acquired pursuant to a registration statement that has been
declared effective under the Act, shall bear a legend substantially in the
following form:

        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
        LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
        TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT
        AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS,
        PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE ISSUER OF THESE
        SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
        SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR
        RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES
        LAWS.

Any certificate for any Warrant Shares issued at any time in exchange or
substitution for any certificate for any Warrant Shares bearing such legend
(except a new certificate for any Warrant Shares issued after the acquisition of
such Warrant Shares pursuant to a registration statement that has been declared
effective under the Act) shall also bear such legend unless, in the opinion of
counsel for the Company, the Warrant Shares represented thereby need no longer
be subject to the restriction contained herein. The provisions of this Section
10 shall be binding upon all subsequent Holders of certificates for Warrant
Shares bearing the above legend and all subsequent Holders of this Warrant, if
any. In addition in connection with the issuance of this Warrant, the Holder
specifically represents to the Company by acceptance of this Warrant as follows:

                                       5
<PAGE>   6

               (a) The Holder is aware of the Company's business affairs and
financial condition, and has acquired information about the Company sufficient
to reach an informed and knowledgeable decision to acquire this Warrant. The
Holder is acquiring this Warrant for its own account for investment purposes
only and not with a view to, or for the resale in connection with, any
"distribution" thereof in violation of the Act.

               (b) The Holder understands that this Warrant has not been
registered under the Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of the Holder's
investment intent as expressed herein.

               (c) The Holder further understands that this Warrant must be held
indefinitely unless subsequently registered under the Act and qualified under
any applicable state securities laws, or unless exemptions from registration and
qualification are otherwise available. Moreover, the Holder understands that the
Company is under no obligation to register and qualify this Warrant.

               (d) The Holder is aware of the provisions of Rule 144 promulgated
under the Act, which, in substance, permit limited public resale of "restricted
securities" acquired, directly or indirectly, from the issuer thereof (or from
an affiliate of such issuer), in a non-public offering subject to the
satisfaction of certain conditions, if applicable, including, among other
things: The availability of certain public information about the Company, the
resale occurring not less than one year after the party has purchased and paid
for the securities to be sold; the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934, as
amended) and the amount of securities being sold during any three month period
not exceeding the specified limitations stated therein.

               (e) The Holder further understands that at the time it wishes to
sell this Warrant there may be no public market upon which to make such a sale,
and that, even if such a public market then exits, the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, the Holder may be precluded from selling this Warrant under Rule 144
even if the two year minimum holding period had been satisfied.

               (f) The Holder further understands that in the event all of the
requirements of Rule 144 are not satisfied, registration under the Act,
compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
staff of the Securities and Exchange Commission (the "SEC") has expressed its
opinion that persons proposing to sell private placement securities other than
in a registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.

        SECTION 11. EXPIRATION DATE. This Warrant shall expire and shall be
wholly void and have no effect after 5:00 p.m. on the fifth anniversary of the
date hereof.

                                       6
<PAGE>   7

        SECTION 12. NO VOTING OR DIVIDEND RIGHTS; LIMITATION OF LIABILITY.
Nothing contained in this Warrant shall be construed as conferring upon the
Holder hereof the right to vote or to consent or to receive notice as a
shareholder of the Company or any other matters or any rights whatsoever as a
shareholder of the Company. No dividends or interest shall be payable or accrued
in respect of this Warrant or the interest represented hereby or the shares
purchasable hereunder until, and only to the extent that, this Warrant shall
have been exercised. No provisions hereof, in the absence of affirmative action
by the holder to purchase shares of Series EE Preferred, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such Holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by its creditors.

        SECTION 13. MARKET STANDOFF. The holder of this Warrant, by acceptance
hereof, agrees that such holder will not, without the prior written consent of
the lead underwriter of the initial public offering of the Common Stock of the
Company pursuant to a registration statement filed under the Act (the
"Offering"), directly or indirectly offer to sell, contract to sell (including,
without limitation, any short sale), grant any option for the sale of, acquire
any option to dispose of, or otherwise dispose of any Warrant Shares for a
period of 180 days following the day on which the registration statement filed
on behalf of the Company in connection with the Offering shall become effective
by order of the SEC.

        SECTION 14. GOVERNING LAW. This Warrant is delivered in the State of
California and shall be construed in accordance with and governed by the laws of
that State.

        SECTION 15. MODIFICATION AND WAIVER. Neither this Warrant nor any term
hereof may be amended, waived, discharged or terminated other than by an
instrument in writing signed by the Company and by the Holder hereof.

        SECTION 16. NOTICES. Any notice, request or other document required or
permitted to be given or delivered to the Holder hereof or the Company shall be
delivered or shall be sent by certified mail, postage prepaid, to each such
Holder at its address as shown on the books of the Company or to the Company at
the address indicated therefor in the first paragraph of this Warrant.

        SECTION 17. DESCRIPTIVE HEADINGS AND GOVERNING LAW. The description
headings of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. This Warrant
shall be construed and enforced in accordance with, and the rights of the
parties shall be governed by, the laws of the State of California.

        SECTION 18. ENTIRE AGREEMENT. This Warrant constitutes the entire
agreement between the parties pertaining to the subject matter herein and
supersedes all prior and contemporaneous agreements, representation and
undertakings of the parties.

the Consultant is providing to the Company, or because the Consultant is not a
natural person, or as otherwise provided by Rule 701, unless the Company

6.      Option Provisions.

        Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and, if certificates are issued, a separate certificate or certificates
will be issued for shares of Common Stock purchased on exercise of each type of
Option. The provisions of separate Options need not be identical, but each
Option shall include (through incorporation of provisions hereof by reference in
the Option or otherwise) the substance of each of the following provisions:

        (a) TERM. Subject to the provisions of subsection 5(b) regarding Ten
Percent Stockholders, no Option granted prior to the Listing Date shall be
exercisable after the expiration of ten (10) years from the date it was granted,
and no Incentive Stock Option granted on or after the Listing Date shall be
exercisable after the expiration of ten (10) years from the date it was granted.

        (b) EXERCISE PRICE OF AN INCENTIVE STOCK OPTION. Subject to the
provisions of subsection 5(b) regarding Ten Percent Stockholders, the exercise
price of each Incentive Stock Option shall be not less than one hundred percent
(100%) of the Fair Market Value of the Common Stock subject to the Option on the
date the Option is granted. Notwithstanding the foregoing, an Incentive Stock
Option may be granted with an exercise price lower than that set forth in the
preceding sentence if such Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section
424(a) of the Code.

        (c) EXERCISE PRICE OF A NONSTATUTORY STOCK OPTION. Subject to the
provisions of subsection 5(b) regarding Ten Percent Stockholders, the exercise
price of each Nonstatutory Stock Option granted prior to the Listing Date shall
be not less than eighty-five percent (85%) of the Fair Market Value of the
Common Stock subject to the Option on the date the Option is granted. The
exercise price of each Nonstatutory Stock Option granted on or after the Listing
Date shall be not less than eighty-five percent (85%) of the Fair Market Value
of the Common Stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with
an exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(a) of the Code.

        (d) CONSIDERATION. The purchase price of Common Stock acquired pursuant
to an Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised or (ii) at
the discretion of the Board at the time of the grant of the Option (or
subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the
Company of other Common Stock, (2) according to a deferred payment or other
similar arrangement with the Optionholder or (3) in any other form of legal
consideration that may be acceptable to the Board. Unless otherwise specifically
provided in the Option, the purchase price of Common Stock acquired pursuant to
an Option that is paid by delivery to the Company of other Common Stock
acquired, directly or indirectly from the Company, shall be paid only by shares
of the Common Stock of the Company that have been held for more than six (6)
months (or such longer or shorter period of time required to avoid a charge to
earnings for financial

                                       8.
<PAGE>   9
accounting purposes). At any time that the Company is incorporated in Delaware,
payment of the Common Stock's "par value," as defined in the Delaware General
Corporation Law, shall not be made by deferred payment.

        In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

        (e) TRANSFERABILITY OF AN INCENTIVE STOCK OPTION. An Incentive Stock
Option shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Optionholder
only by the Optionholder. Notwithstanding the foregoing, the Optionholder may,
by delivering written notice to the Company, in a form satisfactory to the
Company, designate a third party who, in the event of the death of the
Optionholder, shall thereafter be entitled to exercise the Option.

        (f) TRANSFERABILITY OF A NONSTATUTORY STOCK OPTION. A Nonstatutory Stock
Option granted prior to the Listing Date shall not be transferable except by
will or by the laws of descent and distribution and, to the extent provided in
the Option Agreement, to such further extent as permitted by Section
260.140.41(d) of Title 10 of the California Code of Regulations at the time of
the grant of the Option, and shall be exercisable during the lifetime of the
Optionholder only by the Optionholder. A Nonstatutory Stock Option granted on or
after the Listing Date shall be transferable to the extent provided in the
Option Agreement. If the Nonstatutory Stock Option does not provide for
transferability, then the Nonstatutory Stock Option shall not be transferable
except by will or by the laws of descent and distribution and shall be
exercisable during the lifetime of the Optionholder only by the Optionholder.
Notwithstanding the foregoing, the Optionholder may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionholder, shall thereafter be
entitled to exercise the Option.

        (g) VESTING GENERALLY. The total number of shares of Common Stock
subject to an Option may, but need not, vest and therefore become exercisable in
periodic installments that may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be
exercised (which may be based on performance or other criteria) as the Board may
deem appropriate. The vesting provisions of individual Options may vary. The
provisions of this subsection 6(g) are subject to any Option provisions
governing the minimum number of shares of Common Stock as to which an Option may
be exercised.

        (h) MINIMUM VESTING PRIOR TO THE LISTING DATE. Notwithstanding the
foregoing subsection 6(g), to the extent that the following restrictions on
vesting are required by Section 260.140.41(f) of Title 10 of the California Code
of Regulations at the time of the grant of the Option, then:

               (i) Options granted prior to the Listing Date to an Employee who
is not an Officer, Director or Consultant shall provide for vesting of the total
number of shares of Common Stock at a rate of at least twenty percent (20%) per
year over five (5) years from the

                                       9.
<PAGE>   10
date the Option was granted, subject to reasonable conditions such as continued
employment; and

               (ii) Options granted prior to the Listing Date to Officers,
Directors or Consultants may be made fully exercisable, subject to reasonable
conditions such as continued employment, at any time or during any period
established by the Company.

        (i) TERMINATION OF CONTINUOUS SERVICE. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise such Option as of the date of
termination) but only within such period of time ending on the earlier of (i)
the date three (3) months following the termination of the Optionholder's
Continuous Service (or such longer or shorter period specified in the Option
Agreement, which period shall not be less than thirty (30) days for Options
granted prior to the Listing Date unless such termination is for cause), or (ii)
the expiration of the term of the Option as set forth in the Option Agreement.
If, after termination, the Optionholder does not exercise his or her Option
within the time specified in the Option Agreement, the Option shall terminate.

        (j) EXTENSION OF TERMINATION DATE. An Optionholder's Option Agreement
may also provide that if the exercise of the Option following the termination of
the Optionholder's Continuous Service (other than upon the Optionholder's death
or Disability) would be prohibited at any time solely because the issuance of
shares of Common Stock would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in subsection 6(a) or (ii) the
expiration of a period of three (3) months after the termination of the
Optionholder's Continuous Service during which the exercise of the Option would
not be in violation of such registration requirements.

        (k) DISABILITY OF OPTIONHOLDER. In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise such Option as of the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve (12)
months following such termination (or such longer or shorter period specified in
the Option Agreement, which period shall not be less than six (6) months for
Options granted prior to the Listing Date) or (ii) the expiration of the term of
the Option as set forth in the Option Agreement. If, after termination, the
Optionholder does not exercise his or her Option within the time specified
herein, the Option shall terminate.

        (l) DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the period (if any) specified in the Option Agreement
after the termination of the Optionholder's Continuous Service for a reason
other than death, then the Option may be exercised (to the extent the
Optionholder was entitled to exercise such Option as of the date of death) by
the Optionholder's estate, by a person who acquired the right to exercise the
Option by bequest or inheritance or by a person designated to exercise the
option upon the Optionholder's death pursuant to subsection 6(e) or 6(f), but
only within the period ending on the earlier of (1) the date eighteen (18)
months following the date of death (or such longer or shorter period specified
in

                                      10.
<PAGE>   11
the Option Agreement, which period shall not be less than six (6) months for
Options granted prior to the Listing Date) or (2) the expiration of the term of
such Option as set forth in the Option Agreement. If, after death, the Option is
not exercised within the time specified herein, the Option shall terminate.

        (m) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares of Common Stock subject to the Option prior to the full vesting of
the Option. Subject to the "Repurchase Limitation" in subsection 11(h), any
unvested shares of Common Stock so purchased may be subject to a repurchase
option in favor of the Company or to any other restriction the Board determines
to be appropriate.

        (n) RIGHT OF REPURCHASE. Subject to the "Repurchase Limitation" in
subsection 11(h), the Option may, but need not, include a provision whereby the
Company may elect, prior to the Listing Date, to repurchase all or any part of
the vested shares of Common Stock acquired by the Optionholder pursuant to the
exercise of the Option.

        (o) RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionholder of
the intent to transfer all or any part of the shares of Common Stock received
upon the exercise of the Option. Except as expressly provided in this subsection
6(o), such right of first refusal shall otherwise comply with any applicable
provisions of the Bylaws of the Company.

        (p) RE-LOAD OPTIONS.

               (i) Without in any way limiting the authority of the Board to
make or not to make grants of Options hereunder, the Board shall have the
authority (but not an obligation) to include as part of any Option Agreement a
provision entitling the Optionholder to a further Option (a "Re-Load Option") in
the event the Optionholder exercises the Option evidenced by the Option
Agreement, in whole or in part, by surrendering other shares of Common Stock in
accordance with this Plan and the terms and conditions of the Option Agreement.
Unless otherwise specifically provided in the Option, the Optionholder shall not
surrender shares of Common Stock acquired, directly or indirectly from the
Company, unless such shares have been held for more than six (6) months (or such
longer or shorter period of time required to avoid a charge to earnings for
financial accounting purposes).

               (ii) Any such Re-Load Option shall (1) provide for a number of
shares of Common Stock equal to the number of shares of Common Stock surrendered
as part or all of the exercise price of such Option; (2) have an expiration date
which is the same as the expiration date of the Option the exercise of which
gave rise to such Re-Load Option; and (3) have an exercise price which is equal
to one hundred percent (100%) of the Fair Market Value of the Common Stock
subject to the Re-Load Option on the date of exercise of the original Option.
Notwithstanding the foregoing, a Re-Load Option shall be subject to the same
exercise price and term provisions heretofore described for Options under the
Plan.

                                      11.
<PAGE>   12
        Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollar ($100,000) annual limitation on the exercisability of Incentive Stock
Options described in subsection 11(d) and in Section 422(d) of the Code. There
shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
be subject to the availability of sufficient shares of Common Stock under
subsection 4(a) and the "Section 162(m) Limitation" on the grants of Options
under subsection 5(c) and shall be subject to such other terms and conditions as
the Board may determine which are not inconsistent with the express provisions
of the Plan regarding the terms of Options.

7.      NON-EMPLOYEE DIRECTOR STOCK OPTIONS.

        Without any further action of the Board, each Non-Employee Director
shall be granted Nonstatutory Stock Options as described in subsections 7(a) and
7(b) (collectively, "Non-Employee Director Options"). Each Non-Employee Director
Option shall include the substance of the terms set forth in subsections 7(c)
through 7(k).

        (a) INITIAL GRANTS. After the IPO Date, each person who is elected or
appointed for the first time to be a Non-Employee Director automatically shall,
upon the date of his or her initial election or appointment to be a Non-Employee
Director by the Board or stockholders of the Company, be granted an Initial
Grant to purchase twenty-five thousand (25,000) shares of Common Stock on the
terms and conditions set forth herein. For purposes of the foregoing sentence,
on the IPO Date, each person then serving as a Non-Employee Director and who has
not previously been granted options to acquire Common Stock shall be deemed to
have been initially elected as a Non-Employee Director on such date.

        (b) ANNUAL GRANTS. After the IPO Date, each person who is a Non-Employee
Director on the Board on the day after the annual stockholders' meeting, shall,
on that date, be granted an Annual Grant to purchase six thousand five hundred
(6,500) shares of Common Stock on the terms and conditions set forth herein.
Notwithstanding the foregoing, the number of shares of Common Stock subject to
an Annual Grant to a Non-Employee Director that has not served in that capacity
for the entire period since the preceding annual stockholders' meeting shall be
reduced, pro rata, for each full quarter the person did not serve during such
period.

        (c) TERM. Each Non-Employee Director Option shall have a term of ten
(10) years from the date it is granted.

        (d) EXERCISE PRICE. The exercise price of each Non-Employee Director
Option shall be one hundred percent (100%) of the Fair Market Value of the stock
subject to the Non-Employee Director Option on the date of grant.
Notwithstanding the foregoing, a Non-Employee Director Option may be granted
with an exercise price lower than that set forth in the preceding sentence if
such Non-Employee Director Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section
424(a) of the Code.

                                      12.
<PAGE>   13
        (e) VESTING. Each Initial Grant shall vest fifty percent (50%) per year
from the date on which it is granted. Each Annual Grant shall vest fifty percent
(50%) per year from the date on which it is granted.

        (f) CONSIDERATION. The purchase price of stock acquired pursuant to a
Non-Employee Director Option may be paid, to the extent permitted by applicable
statutes and regulations, in any combination of (i) cash or check, (ii) delivery
to the Company of other Common Stock, (ii) deferred payment or (iv) any other
form of legal consideration that may be acceptable to the Board and provided in
the Non-Employee Director Option Agreement; provided, however, that at any time
that the Company is incorporated in Delaware, payment of the Common Stock's "par
value," as defined in the Delaware General Corporation Law, shall not be made by
deferred payment. In the case of any deferred payment arrangement, interest
shall be compounded at least annually and shall be charged at the minimum rate
of interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

        (g) TRANSFERABILITY. A Non-Employee Director Option shall not be
transferable except by will or by the laws of descent and distribution and shall
be exercisable during the lifetime of the Non-Employee Director only by the
Non-Employee Director except as otherwise provided in a Stock Award Agreement.
Notwithstanding the foregoing, the Non-Employee Director may, by delivering
written notice to the Company, in a form satisfactory to the Company, designate
a third party who, in the event of the death of the Non-Employee Director, shall
thereafter be entitled to exercise the Non-Employee Director Option.

        (h) TERMINATION OF CONTINUOUS SERVICE. In the event a Non-Employee
Director's Continuous Service terminates (other than upon the Non-Employee
Director's death or Disability), the Non-Employee Director may exercise his or
her Non-Employee Director Option (to the extent that the Non-Employee Director
was entitled to exercise it as of the date of termination) but only within such
period of time ending on the earlier of (i) the date three (3) months following
the termination of the Non-Employee Director's Continuous Service, or (ii) the
expiration of the term of the Non-Employee Director Option as set forth in the
Non-Employee Director Option Agreement. If, after termination, the Non-Employee
Director does not exercise his or her Non-Employee Director Option within the
time specified in the Non-Employee Director Option Agreement, the Non-Employee
Director Option shall terminate.

        (i) EXTENSION OF TERMINATION DATE. If the exercise of the Non-Employee
Director Option following the termination of the Non-Employee Director's
Continuous Service (other than upon the Non-Employee Director's death or
Disability) would be prohibited at any time solely because the issuance of
shares would violate the registration requirements under the Securities Act,
then the Non-Employee Director Option shall terminate on the earlier of (i) the
expiration of the term of the Non-Employee Director Option set forth in
subsection 7(c) or (ii) the expiration of a period of three (3) months after the
termination of the Non-Employee Director's Continuous Service during which the
exercise of the Non-Employee Director Option would not violate such registration
requirements.

        (j) DISABILITY OF NON-EMPLOYEE DIRECTOR. In the event a Non-Employee
Director's Continuous Service terminates as a result of the Non-Employee
Director's Disability, the Non-

                                      13.
<PAGE>   14
Employee Director may exercise his or her Non-Employee Director Option (to the
extent that the Non-Employee Director was entitled to exercise it as of the date
of termination), but only within such period of time ending on the earlier of
(i) the date twelve (12) months following such termination or (ii) the
expiration of the term of the Non-Employee Director Option as set forth in the
Non-Employee Director Option Agreement. If, after termination, the Non-Employee
Director does not exercise his or her Non-Employee Director Option within the
time specified herein, the Non-Employee Director Option shall terminate.

        (k) DEATH OF NON-EMPLOYEE DIRECTOR. In the event (i) a Non-Employee
Director's Continuous Service terminates as a result of the Non-Employee
Director's death or (ii) the Non-Employee Director dies within the three-month
period after the termination of the Non-Employee Director's Continuous Service
for a reason other than death, then the Non-Employee Director Option may be
exercised (to the extent the Non-Employee Director was entitled to exercise the
Non-Employee Director Option as of the date of death) by the Non-Employee
Director's estate, by a person who acquired the right to exercise the
Non-Employee Director Option by bequest or inheritance or by a person designated
to exercise the Non-Employee Director Option upon the Non-Employee Director's
death, but only within the period ending on the earlier of (1) the date eighteen
(18) months following the date of death or (2) the expiration of the term of
such Non-Employee Director Option as set forth in the Non-Employee Director
Option Agreement. If, after death, the Non-Employee Director Option is not
exercised within the time specified herein, the Non-Employee Director Option
shall terminate.

8.      Provisions of Stock Awards other than Options.

        (a) STOCK BONUS AWARDS. Each stock bonus agreement shall be in such form
and shall contain such terms and conditions as the Board shall deem appropriate.
The terms and conditions of stock bonus agreements may change from time to time,
and the terms and conditions of separate stock bonus agreements need not be
identical, but each stock bonus agreement shall include (through incorporation
of provisions hereof by reference in the agreement or otherwise) the substance
of each of the following provisions:

               (i) CONSIDERATION. A stock bonus may be awarded in consideration
for past services actually rendered to the Company or an Affiliate for its
benefit.

               (ii) VESTING. Subject to the "Repurchase Limitation" in
subsection 11(h), shares of Common Stock awarded under the stock bonus agreement
may, but need not, be subject to a share repurchase option in favor of the
Company in accordance with a vesting schedule to be determined by the Board.

               (iii) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Subject to
the "Repurchase Limitation" in subsection 11(h), in the event a Participant's
Continuous Service terminates, the Company may reacquire any or all of the
shares of Common Stock held by the Participant which have not vested as of the
date of termination under the terms of the stock bonus agreement.

               (iv) TRANSFERABILITY. For a stock bonus award made before the
Listing Date, rights to acquire shares of Common Stock under the stock bonus
agreement shall not be

                                      14.
<PAGE>   15
transferable except by will or by the laws of descent and distribution and shall
be exercisable during the lifetime of the Participant only by the Participant.
For a stock bonus award made on or after the Listing Date, rights to acquire
shares of Common Stock under the stock bonus agreement shall be transferable by
the Participant only upon such terms and conditions as are set forth in the
stock bonus agreement, as the Board shall determine in its discretion, so long
as Common Stock awarded under the stock bonus agreement remains subject to the
terms of the stock bonus agreement.

        (b) RESTRICTED STOCK AWARDS. Each restricted stock purchase agreement
shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate. The terms and conditions of the restricted stock
purchase agreements may change from time to time, and the terms and conditions
of separate restricted stock purchase agreements need not be identical, but each
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions:

               (i) PURCHASE PRICE. Subject to the provisions of subsection 5(b)
regarding Ten Percent Stockholders, the purchase price under each restricted
stock purchase agreement shall be such amount as the Board shall determine and
designate in such restricted stock purchase agreement. For restricted stock
awards made prior to the Listing Date, the purchase price shall not be less than
eighty-five percent (85%) of the Common Stock's Fair Market Value on the date
such award is made or at the time the purchase is consummated. For restricted
stock awards made on or after the Listing Date, the purchase price shall not be
less than eighty-five percent (85%) of the Common Stock's Fair Market Value on
the date such award is made or at the time the purchase is consummated.

               (ii) CONSIDERATION. The purchase price of Common Stock acquired
pursuant to the restricted stock purchase agreement shall be paid either: (i) in
cash at the time of purchase; (ii) at the discretion of the Board, according to
a deferred payment or other similar arrangement with the Participant; or (iii)
in any other form of legal consideration that may be acceptable to the Board in
its discretion; provided, however, that at any time that the Company is
incorporated in Delaware, then payment of the Common Stock's "par value," as
defined in the Delaware General Corporation Law, shall not be made by deferred
payment.

               (iii) VESTING. Subject to the "Repurchase Limitation" in
subsection 11(h), shares of Common Stock acquired under the restricted stock
purchase agreement may, but need not, be subject to a share repurchase option in
favor of the Company in accordance with a vesting schedule to be determined by
the Board.

               (iv) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Subject to
the "Repurchase Limitation" in subsection 11(h), in the event a Participant's
Continuous Service terminates, the Company may repurchase or otherwise reacquire
any or all of the shares of Common Stock held by the Participant which have not
vested as of the date of termination under the terms of the restricted stock
purchase agreement.

               (v) TRANSFERABILITY. For a restricted stock award made before the
Listing Date, rights to acquire shares of Common Stock under the restricted
stock purchase agreement

                                      15.
<PAGE>   16
shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant. For a restricted stock award made on or after the
Listing Date, rights to acquire shares of Common Stock under the restricted
stock purchase agreement shall be transferable by the Participant only upon such
terms and conditions as are set forth in the restricted stock purchase
agreement, as the Board shall determine in its discretion, so long as Common
Stock awarded under the restricted stock purchase agreement remains subject to
the terms of the restricted stock purchase agreement.

9.      Covenants of the Company.

        (a) AVAILABILITY OF SHARES. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.

        (b) SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from
each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Stock Awards and to issue and sell shares
of Common Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any
such Stock Award. If, after reasonable efforts, the Company is unable to obtain
from any such regulatory commission or agency the authority which counsel for
the Company deems necessary for the lawful issuance and sale of Common Stock
under the Plan, the Company shall be relieved from any liability for failure to
issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained.

10.     Use of Proceeds from Stock.

        Proceeds from the sale of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company.

11.     Miscellaneous.

        (a) ACCELERATION OF EXERCISABILITY AND VESTING. The Board shall have the
power to accelerate the time at which a Stock Award may first be exercised or
the time during which a Stock Award or any part thereof will vest in accordance
with the Plan, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.

        (b) STOCKHOLDER RIGHTS. No Participant shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

        (c) NO EMPLOYMENT OR OTHER SERVICE RIGHTS. Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of

                                      16.
<PAGE>   17
a Consultant pursuant to the terms of such Consultant's agreement with the
Company or an Affiliate or (iii) the service of a Director pursuant to the
Bylaws of the Company or an Affiliate, and any applicable provisions of the
corporate law of the state in which the Company or the Affiliate is
incorporated, as the case may be.

        (d) INCENTIVE STOCK OPTION $100,000 LIMITATION. To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which Incentive Stock Options are exercisable for the first time
by any Optionholder during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

        (e) INVESTMENT ASSURANCES. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to
give written assurances satisfactory to the Company as to the Participant's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (ii) to
give written assurances satisfactory to the Company stating that the Participant
is acquiring Common Stock subject to the Stock Award for the Participant's own
account and not with any present intention of selling or otherwise distributing
the Common Stock. The foregoing requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (1) the issuance of the shares of
Common Stock upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration
statement under the Securities Act or (2) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the Common Stock.

        (f) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of a
Stock Award Agreement, the Participant may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of Common
Stock under a Stock Award by any of the following means (in addition to the
Company's right to withhold from any compensation paid to the Participant by the
Company) or by a combination of such means: (i) tendering a cash payment; (ii)
authorizing the Company to withhold shares of Common Stock from the shares of
Common Stock otherwise issuable to the Participant as a result of the exercise
or acquisition of Common Stock under the Stock Award, provided, however, that no
shares of Common Stock are withheld with a value exceeding the minimum amount of
tax required to be withheld by law; or (iii) delivering to the Company owned and
unencumbered shares of Common Stock.

        (g) INFORMATION OBLIGATION. Prior to the Listing Date, to the extent
required by Section 260.140.46 of Title 10 of the California Code of
Regulations, the Company shall deliver financial statements to Participants at
least annually. This subsection 11(g) shall not apply to key

                                      17.
<PAGE>   18
Employees whose duties in connection with the Company assure them access to
equivalent information.

        (h) REPURCHASE LIMITATION. The terms of any repurchase option shall be
specified in the Stock Award and may be either at Fair Market Value at the time
of repurchase or at not less than the original purchase price. To the extent
required by Section 260.140.41 and Section 260.140.42 of Title 10 of the
California Code of Regulations at the time a Stock Award is made, any repurchase
option contained in a Stock Award granted prior to the Listing Date to a person
who is not an Officer, Director or Consultant shall be upon the terms described
below:

               (i) FAIR MARKET VALUE. If the repurchase option gives the Company
the right to repurchase the shares of Common Stock upon termination of
employment at not less than the Fair Market Value of the shares of Common Stock
to be purchased on the date of termination of Continuous Service, then (i) the
right to repurchase shall be exercised for cash or cancellation of purchase
money indebtedness for the shares of Common Stock within ninety (90) days of
termination of Continuous Service (or in the case of shares of Common Stock
issued upon exercise of Stock Awards after such date of termination, within
ninety (90) days after the date of the exercise) or such longer period as may be
agreed to by the Company and the Participant (for example, for purposes of
satisfying the requirements of Section 1202(c)(3) of the Code regarding
"qualified small business stock") and (ii) the right terminates when the shares
of Common Stock become publicly traded.

               (ii) ORIGINAL PURCHASE PRICE. If the repurchase option gives the
Company the right to repurchase the shares of Common Stock upon termination of
Continuous Service at the original purchase price, then (i) the right to
repurchase at the original purchase price shall lapse at the rate of at least
twenty percent (20%) of the shares of Common Stock per year over five (5) years
from the date the Stock Award is granted (without respect to the date the Stock
Award was exercised or became exercisable) and (ii) the right to repurchase
shall be exercised for cash or cancellation of purchase money indebtedness for
the shares of Common Stock within ninety (90) days of termination of Continuous
Service (or in the case of shares of Common Stock issued upon exercise of
Options after such date of termination, within ninety (90) days after the date
of the exercise) or such longer period as may be agreed to by the Company and
the Participant (for example, for purposes of satisfying the requirements of
Section 1202(c)(3) of the Code regarding "qualified small business stock").

12.     Adjustments upon Changes in Stock.

        (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the Common
Stock subject to the Plan, or subject to any Stock Award, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
pursuant to subsection 4(a) and the maximum number of securities subject to
award to any person pursuant to subsection 5(c), and the outstanding Stock
Awards will be appropriately adjusted in the class(es) and number of securities
and price per share of Common Stock subject to such outstanding Stock Awards.
The

                                      18.
<PAGE>   19
Board shall make such adjustments, and its determination shall be final, binding
and conclusive. (The conversion of any convertible securities of the Company
shall not be treated as a transaction "without receipt of consideration" by the
Company.)

        (b) DISSOLUTION OR LIQUIDATION. In the event of a dissolution or
liquidation of the Company, then all outstanding Stock Awards shall terminate
immediately prior to such event.

        (c) ASSET SALE, MERGER, CONSOLIDATION OR REVERSE MERGER. In the event of
(i) a sale, lease or other disposition of all or substantially all of the assets
of the Company, (ii) a merger or consolidation in which the Company is not the
surviving corporation or (iii) a reverse merger in which the Company is the
surviving corporation but the shares of Common Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise (individually, a "Corporate
Transaction"), then any surviving corporation or acquiring corporation shall
assume any Stock Awards outstanding under the Plan or shall substitute similar
stock awards (including an award to acquire the same consideration paid to the
stockholders in the Corporate Transaction for those outstanding under the Plan).
In the event any surviving corporation or acquiring corporation refuses to
assume such Stock Awards or to substitute similar stock awards for those
outstanding under the Plan, then with respect to Stock Awards held by
Participants whose Continuous Service has not terminated, the vesting of such
Stock Awards (and, if applicable, the time during which such Stock Awards may be
exercised) shall be accelerated in full, and the Stock Awards shall terminate if
not exercised (if applicable) at or prior to the Corporate Transaction. With
respect to any other Stock Awards outstanding under the Plan, such Stock Awards
shall terminate if not exercised (if applicable) prior to the Corporate
Transaction.

amend the Plan. However, except as provided in Section 12 relating to
adjustments upon changes in Common Stock, no amendment shall be effective unless

is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3
or any Nasdaq or securities exchange listing requirements.

        (b) STOCKHOLDER APPROVAL. The Board may, in its sole discretion, submit
any other amendment to the Plan for stockholder approval, including, but not

Section 162(m) of the Code and the regulations thereunder regarding the
exclusion of performance-based compensation from the limit on corporate
deductibility of compensation paid to certain executive officers.

        (c) CONTEMPLATED AMENDMENTS. It is expressly contemplated that the Board
may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Participant and (ii) the Participant
consents in writing.

        (e) AMENDMENT OF STOCK AWARDS. The Board at any time, and from time to
time, may amend the terms of any one or more Stock Awards; provided, however,

granted under the Plan while the Plan is suspended or after it is terminated.

        (b) NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan shall
not impair rights and obligations under any Stock Award granted while the Plan
is in effect except with the written consent of the Participant.

Award shall be exercised (or, in the case of a stock bonus, shall be granted)

which approval shall be within twelve (12) months before or after the date the
Plan is adopted by the Board.

                                     FORM OF
                             STOCK OPTION AGREEMENT
                   (INCENTIVE AND NONSTATUTORY STOCK OPTIONS)

Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock
Option Agreement, Repeater Technologies, Inc. (the "Company") has granted you an
option under its 2000 Equity Incentive Plan (the "Plan") to purchase the number
of shares of the Company's Common Stock indicated in your Grant Notice at the
exercise price indicated in your Grant Notice. Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

The details of your option are as follows:

        1. VESTING. Subject to the limitations and provisions contained herein,
your option will vest as provided in your Grant Notice, provided that vesting
will cease upon the termination of your Continuous Service.

        2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common
Stock subject to your option and your exercise price per share referenced in
your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as provided in the Plan.

        3. EXERCISE PRIOR TO VESTING ("EARLY EXERCISE"). If permitted in your
Grant Notice (i.e., the "Exercise Schedule" indicates that "Early Exercise" of
your option is permitted) and subject to the provisions of your option, you may
elect at any time that is both (i) during the period of your Continuous Service
and (ii) during the term of your option, to exercise all or part of your option,
including the nonvested portion of your option; provided, however, that:

               a. a partial exercise of your option shall be deemed to cover
first vested shares of Common Stock and then the earliest vesting installment of
unvested shares of Common Stock;

               b. any shares of Common Stock so purchased from installments that
have not vested as of the date of exercise shall be subject to the purchase
option in favor of the Company as described in the Company's form of Early
Exercise Stock Purchase Agreement;

               c. you shall enter into the Company's form of Early Exercise
Stock Purchase Agreement with a vesting schedule that will result in the same
vesting as if no early exercise had occurred; and

               d. if your option is an incentive stock option, then, as provided
in the Plan, to the extent that the aggregate Fair Market Value (determined at
the time of grant) of the shares of Common Stock with respect to which your
option plus all other incentive stock options you hold

                                       1.
<PAGE>   24
are exercisable for the first time by you during any calendar year (under all
plans of the Company and its Affiliates) exceeds one hundred thousand dollars
($100,000), your option(s) or portions thereof that exceed such limit (according
to the order in which they were granted) shall be treated as nonstatutory stock
options.

        4. METHOD OF PAYMENT. Payment of the exercise price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the
exercise price in cash or by check or in any other manner PERMITTED BY YOUR
GRANT NOTICE, which may include one or more of the following:

               a. In the Company's sole discretion at the time your option is
exercised and provided that at the time of exercise the Common Stock is publicly
traded and quoted regularly in The Wall Street Journal, pursuant to a program
developed under Regulation T as promulgated by the Federal Reserve Board that,
prior to the issuance of Common Stock, results in either the receipt of cash (or
check) by the Company or the receipt of irrevocable instructions to pay the
aggregate exercise price to the Company from the sales proceeds.

               b. Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery" for these purposes, in the sole discretion of the Company at the time
you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by
the Company. Notwithstanding the foregoing, you may not exercise your option by
tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of
the Company's stock.

               c. Pursuant to the following deferred payment alternative:

                      1) Not less than one hundred percent (100%) of the
aggregate exercise price, plus accrued interest, shall be due four (4) years
from date of exercise or, at the Company's election, upon termination of your
Continuous Service.

                      2) Interest shall be compounded at least annually and
shall be charged at the minimum rate of interest necessary to avoid the
treatment as interest, under any applicable provisions of the Code, of any
portion of any amounts other than amounts stated to be interest under the
deferred payment arrangement.

                      3) At any time that the Company is incorporated in
Delaware, payment of the Common Stock's "par value," as defined in the Delaware
General Corporation Law, shall be made in cash and not by deferred payment.

                      4) In order to elect the deferred payment alternative, you
must, as a part of your written notice of exercise, give notice of the election
of this payment alternative and, in order to secure the payment of the deferred
exercise price to the Company hereunder, if the

                                       2.
<PAGE>   25
Company so requests, you must tender to the Company a promissory note and a
security agreement covering the purchased shares of Common Stock, both in form
and substance satisfactory to the Company, or such other or additional
documentation as the Company may request.

        5. WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock.

        6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise of your option must also comply
with other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not
be in material compliance with such laws and regulations.

        7. TERM. You may not exercise your option before the commencement of its
term or after its term expires. The term of your option commences on the Date of
Grant and expires upon the EARLIEST of the following:

               a. three (3) months after the termination of your Continuous
Service for any reason other than your Disability or death, provided that if
during any part of such three- (3-) month period your option is not exercisable
solely because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

               b. twelve (12) months after the termination of your Continuous
Service due to your Disability;

               c. eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates;

               d. the Expiration Date indicated in your Grant Notice; or

               e. the day before the tenth (10th) anniversary of the Date of
Grant.

If your option is an incentive stock option, note that, to obtain the federal
income tax advantages associated with an "incentive stock option," the Code
requires that at all times beginning on the date of grant of your option and
ending on the day three (3) months before the date of your option's exercise,
you must be an employee of the Company or an Affiliate, except in the event of
your death or Disability. The Company has provided for extended exercisability
of your option under certain circumstances for your benefit but cannot guarantee
that your option will necessarily be treated as an "incentive stock option" if
you continue to provide services to the Company or an Affiliate as a Consultant
or Director after your employment terminates or if you otherwise exercise your
option more than three (3) months after the date your employment terminates.

                                       3.
<PAGE>   26
        8. EXERCISE.

               a. You may exercise the vested portion of your option (and the
unvested portion of your option if your Grant Notice so permits) during its term
by delivering a Notice of Exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

               b. By exercising your option you agree that, as a condition to
any exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of (1) the exercise of
your option, (2) the lapse of any substantial risk of forfeiture to which the
shares of Common Stock are subject at the time of exercise, or (3) the
disposition of shares of Common Stock acquired upon such exercise.

               c. If your option is an incentive stock option, by exercising
your option you agree that you will notify the Company in writing within fifteen
(15) days after the date of any disposition of any of the shares of the Common
Stock issued upon exercise of your option that occurs within two (2) years after
the date of your option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of your option.

               d. By exercising your option you agree that the Company (or a
representative of the underwriter(s)) may, in connection with the first
underwritten registration of the offering of any securities of the Company under
the Securities Act, require that you not sell, dispose of, transfer, make any
short sale of, grant any option for the purchase of, or enter into any hedging
or similar transaction with the same economic effect as a sale, any shares of
Common Stock or other securities of the Company held by you, for a period of
time specified by the underwriter(s) (not to exceed one hundred eighty (180)
days) following the effective date of the registration statement of the Company
filed under the Securities Act. You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company and/or the
underwriter(s) that are consistent with the foregoing or that are necessary to
give further effect thereto. In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to your shares of
Common Stock until the end of such period.

        9. TRANSFERABILITY.

               a. If your option is an incentive stock option, your option is
not transferable, except by will or by the laws of descent and distribution, and
is exercisable during your life only by you. Notwithstanding the foregoing, by
delivering written notice to the Company, in a form satisfactory to the Company,
you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise your option.

               b. If your option is a nonstatutory stock option, your option is
not transferable, except (i) by will or by the laws of descent and distribution,
(ii) with the prior written approval of the Company, by instrument to an inter
vivos or testamentary trust, in a form accepted by the Company, in which the
option is to be passed to beneficiaries upon the death of the trustor (settlor)
and (iii) with the prior written approval of the Company, by gift, in a form
accepted by

                                       4.
<PAGE>   27
the Company, to your "immediate family" as that term is defined in 17 C.F.R.
240.16a-1(e). The term "immediate family" is defined in 17 C.F.R. 240.16a-1(e)
to mean any child, stepchild, grandchild, parent, stepparent, grandparent,
spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law,
brother-in-law, or sister-in-law, and includes adoptive relationships. Your
option is exercisable during your life only by you or a transferee satisfying
the above-stated conditions. The right of a transferee to exercise the
transferred portion of your option after termination of your Continuous Service
shall terminate in accordance with your right to exercise your option as
specified in your option. In the event that your Continuous Service terminates
due to your death, your transferee will be treated as a person who acquired the
right to exercise your option by bequest or inheritance. In addition to the
foregoing, the Company may require, as a condition of the transfer of your
option to a trust or by gift, that your transferee enter into an option transfer
agreement provided by, or acceptable to, the Company. The terms of your option
shall be binding upon your transferees, executors, administrators, heirs,
successors, and assigns. Notwithstanding the foregoing, by delivering written
notice to the Company, in a form satisfactory to the Company, you may designate
a third party who, in the event of your death, shall thereafter be entitled to
exercise your option.

        10. RIGHT OF FIRST REFUSAL. Shares of Common Stock that you acquire upon
exercise of your option are subject to any right of first refusal that may be
described in the Company's bylaws in effect at such time the Company elects to
exercise its right. The Company's right of first refusal shall expire on the
Listing Date.

        11. RIGHT OF REPURCHASE. To the extent provided in the Company's bylaws
as amended from time to time, the Company shall have the right to repurchase all
or any part of the shares of Common Stock you acquire pursuant to the exercise
of your option.

        12. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective shareholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

        13. WITHHOLDING OBLIGATIONS.

               a. At the time you exercise your option, in whole or in part, or
at any time thereafter as requested by the Company, you hereby authorize
withholding from payroll and any other amounts payable to you, and otherwise
agree to make adequate provision for (including by means of a "cashless
exercise" pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Company or an Affiliate, if any, which arise in connection
with your option.

               b. Upon your request and subject to approval by the Company, in
its sole discretion, and compliance with any applicable conditions or
restrictions of law, the Company may withhold from fully vested shares of Common
Stock otherwise issuable to you upon the

                                       5.
<PAGE>   28
exercise of your option a number of whole shares of Common Stock having a Fair
Market Value, determined by the Company as of the date of exercise, not in
excess of the minimum amount of tax required to be withheld by law. If the date
of determination of any tax withholding obligation is deferred to a date later
than the date of exercise of your option, share withholding pursuant to the
preceding sentence shall not be permitted unless you make a proper and timely
election under Section 83(b) of the Code, covering the aggregate number of
shares of Common Stock acquired upon such exercise with respect to which such
determination is otherwise deferred, to accelerate the determination of such tax
withholding obligation to the date of exercise of your option. Notwithstanding
the filing of such election, shares of Common Stock shall be withheld solely
from fully vested shares of Common Stock determined as of the date of exercise
of your option that are otherwise issuable to you upon such exercise. Any
adverse consequences to you arising in connection with such share withholding
procedure shall be your sole responsibility.

               c. You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied. Accordingly, you
may not be able to exercise your option when desired even though your option is
vested, and the Company shall have no obligation to issue a certificate for such
shares of Common Stock or release such shares of Common Stock from any escrow
provided for herein.

        14. NOTICES. Any notices provided for in your option or the Plan shall
be given in writing and shall be deemed effectively given upon receipt or, in
the case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

        15. GOVERNING PLAN DOCUMENT. Your option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your
option, and is further subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted pursuant to
the Plan. In the event of any conflict between the provisions of your option and
those of the Plan, the provisions of the Plan shall control.

I hereby make the following certifications and representations with respect to

which are being acquired by me for my own account upon exercise of the Option as

I acknowledge that the Shares have not been registered under the Securities Act

promulgated under the Securities Act. I warrant and represent to the Company

as permitted under the Securities Act and any applicable state securities laws.

I further acknowledge that I will not be able to resell the Shares for at least
ninety days (90) after the stock of the Company becomes publicly traded (i.e.,

Exchange Act of 1934) under Rule 701 and that more restrictive conditions apply

applicable securities laws.

I further agree that, if required by the Company (or a representative of the
underwriters) in connection with the first underwritten registration of the
offering of any securities of the Company under the Securities Act, I will not
sell, dispose of, transfer, make any short sale of, grant any option for the
purchase of, or enter into any hedging or similar transaction with the same
economic effect as a sale, any Shares or other securities of the Company held by
me, for a period of time specified by the underwriter(s) (not to exceed one
hundred eighty (180) days) following the effective date of the registration
statement of the Company filed under the Securities Act. I further agree to
execute and deliver such other agreements as may be reasonably requested by the

                                     FORM OF
                  NON-EMPLOYEE DIRECTOR STOCK OPTION AGREEMENT
                           (NONSTATUTORY STOCK OPTION)

        Pursuant to your Stock Option Grant Notice ("Grant Notice") and this
Stock Option Agreement, Repeater Technologies, Inc. (the "Company") has granted
you an option under its 2000 Equity Incentive Plan (the "Plan") to purchase the
number of shares of the Company's Common Stock indicated in your Grant Notice at
the exercise price indicated in your Grant Notice. Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

        The details of your option are as follows:

        1. VESTING. Subject to the limitations and provisions contained herein,
your option will vest as provided in your Grant Notice, provided that vesting
will cease upon the termination of your Continuous Service.

        2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common
Stock subject to your option and your exercise price per share referenced in
your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as provided in the Plan.

        3. EXERCISE PRIOR TO VESTING ("EARLY EXERCISE"). If permitted in your
Grant Notice (i.e., the "Exercise Schedule" indicates that "Early Exercise" of
your option is permitted) and subject to the provisions of your option, you may
elect at any time that is both (i) during the period of your Continuous Service
and (ii) during the term of your option, to exercise all or part of your option,
including the nonvested portion of your option; provided, however, that:

               a. a partial exercise of your option shall be deemed to cover
first vested shares of Common Stock and then the earliest vesting installment of
unvested shares of Common Stock;

               b. any shares of Common Stock so purchased from installments that
have not vested as of the date of exercise shall be subject to the purchase
option in favor of the Company as described in the Company's form of Early
Exercise Stock Purchase Agreement; and

               c. you shall enter into the Company's form of Early Exercise
Stock Purchase Agreement with a vesting schedule that will result in the same
vesting as if no early exercise had occurred.

        4. METHOD OF PAYMENT. Payment of the exercise price is due in full upon
exercise of all or any part of your option. You may elect to make payment of the
exercise price in cash or by check or by one or more of the following:

                                       1
<PAGE>   33
               a. Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, pursuant to a
program developed under Regulation T as promulgated by the Federal Reserve Board
that, prior to the issuance of Common Stock, results in either the receipt of
cash (or check) by the Company or the receipt of irrevocable instructions to pay
the aggregate exercise price to the Company from the sales proceeds.

               b. Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, by delivery of
already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery" for these purposes, in the sole discretion of the Company at the time
you exercise your option, shall include delivery to the Company of your
attestation of ownership of such shares of Common Stock in a form approved by
the Company. Notwithstanding the foregoing, you may not exercise your option by
tender to the Company of Common Stock to the extent such tender would violate
the provisions of any law, regulation or agreement restricting the redemption of
the Company's stock.

        5. WHOLE SHARES. You may exercise your option only for whole shares of
Common Stock.

        6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise of your option must also comply
with other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not
be in material compliance with such laws and regulations.

        7. TERM. Except as otherwise provided herein, the term of your option
commences on the Date of Grant and expires upon the earliest of the following:

               a. three (3) months after the termination of your Continuous
Service for any reason other than your Disability or death, provided that if
during any part of such three- (3-) month period your option is not exercisable
solely because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

               b. twelve (12) months after the termination of your Continuous
Service due to your Disability;

               c. eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates; or

               d. the Expiration Date indicated in your Grant Notice.

                                       2
<PAGE>   34
        8. EXERCISE.

               a. You may exercise your option during its term by delivering a
Notice of Exercise (in a form designated by the Company) together with the
exercise price to the Secretary of the Company, or to such other person as the
Company may designate, during regular business hours, together with such
additional documents as the Company may then require.

               b. By exercising your option you agree that, as a condition to
any exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of the exercise of your
option.

               C. TRANSFERABILITY. Your option is not transferable, except (i)
by will or by the laws of descent and distribution, and (ii) to such further
extent as permitted by the Rule as to Use of Form S-8 specified in the General
Instructions of the Form S-8 Registration Statement under the Securities Act.
Your option is exercisable during your life only by you or a transferee
satisfying the above-stated conditions. The right of a transferee to exercise
the transferred portion of your option after termination of your Continuous
Service shall terminate in accordance with your right to exercise your option as
specified in your option. In the event that your Continuous Service terminates
due to your death, your transferee will be treated as a person who acquired the
right to exercise your option by bequest or inheritance. In addition to the
foregoing, the Company may require, as a condition of the transfer of your
option to a trust or by gift, that your transferee enter into an option transfer
agreement provided by, or acceptable to, the Company. The terms of your option
shall be binding upon your transferees, executors, administrators, heirs,
successors, and assigns. Notwithstanding the foregoing, by delivering written
notice to the Company, in a form satisfactory to the Company, you may designate
a third party who, in the event of your death, shall thereafter be entitled to
exercise your option.

        9. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective stockholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

        10. NOTICES. Any notices provided for in your option or the Plan shall
be given in writing and shall be deemed effectively given upon receipt or, in
the case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

        11. ACCELERATION OF VESTING AND PERIOD OF EXERCISABILITY FOLLOWING A
CHANGE IN CONTROL. In the event of the occurrence of a Change in Control (as
described in Section 12(c) of the Plan), your option (or any substituted option)
shall, as of the date of such Change in Control vest in full and become fully
exercisable (if applicable) to the extent not previously vested or exercisable,
and shall (notwithstanding Section 8 of this Stock Option Agreement) continue to
be exercisable for a period of twelve (12) months after termination of

                                       3
<PAGE>   35
your Continuous Service following the Change of Control event or until the
Expiration Date stated in your Grant Notice, whichever period is shorter.

        12. GOVERNING PLAN DOCUMENT. Your option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your
option, and is further subject to all interpretations, amendments, rules and
regulations which may from time to time be promulgated and adopted pursuant to
the Plan. In the event of any conflict between the provisions of your option and
those of the Plan, the provisions of the Plan shall control.
