                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
     The enclosed proxy is solicited on behalf of the Board of Directors (the
"Board") of Metricom, Inc., a Delaware corporation (the "Company"), for use at
the Annual Meeting of Stockholders to be held on May 1, 1997, at 8:30 a.m. local
time (the "Annual Meeting"), or at any adjournment or postponement thereof, for
the purposes set forth herein and in the accompanying Notice of Annual Meeting.
The Annual Meeting will be held at the Company's offices at 980 University
Avenue, Los Gatos, California. The Company intends to mail this proxy statement
and accompanying proxy card on or about March 25, 1997 to all stockholders
entitled to vote at the Annual Meeting.
 
SOLICITATION
 
     The Company will bear the entire cost of solicitation of proxies, including
preparation, assembly, printing and mailing of this proxy statement, the proxy
and any additional information furnished to stockholders. Copies of solicitation
materials will be furnished to banks, brokerage houses, fiduciaries and
custodians holding in their names shares of Common Stock beneficially owned by
others to forward to such beneficial owners. The Company may reimburse persons
representing beneficial owners of Common Stock for their costs of forwarding
solicitation materials to such beneficial owners. Original solicitation of
proxies by mail may be supplemented by telephone, telegram or personal
solicitation by directors, officers or other employees of the Company. No
additional compensation will be paid to directors, officers or other employees
for such services.
 
VOTING RIGHTS AND OUTSTANDING SHARES
 
     Only holders of record of Common Stock at the close of business on March
17, 1997 will be entitled to notice of and to vote at the Annual Meeting. At the
close of business on March 17, 1997, the Company had outstanding and entitled to
vote 13,599,613 shares of Common Stock. Each holder of record of Common Stock on
such date will be entitled to one vote for each share held on all matters to be
voted upon at the Annual Meeting.
 
     All votes will be tabulated by the inspector of elections appointed for the
meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes. Abstentions will be counted towards the
tabulation of votes cast on proposals presented to the stockholders and will
have the same effect as negative votes. Broker non-votes are counted towards a
quorum, but are not counted for any purpose in determining whether a matter has
been approved.
 
REVOCABILITY OF PROXIES
 
     Any person giving a proxy pursuant to this solicitation has the power to
revoke it at any time before it is voted. It may be revoked by filing with the
Secretary of the Company at the Company's principal executive office, 980
University Avenue, Los Gatos, California 95030-2375, a written notice of
revocation or a duly executed proxy bearing a later date, or it may be revoked
by attending the meeting and voting in person. Attendance at the meeting will
not, by itself, revoke a proxy.

STOCKHOLDER PROPOSALS
 
     Proposals of stockholders that are intended to be presented at the
Company's 1998 Annual Meeting of Stockholders must be received by the Company
not later than November 25, 1997 in order to be included in the proxy statement
and proxy relating to that Annual Meeting.
 
                                   PROPOSAL 1
 
                             ELECTION OF DIRECTORS
 
     The Company's Restated Certificate of Incorporation, as amended, and Bylaws
provide that the Board is divided into three classes, each class consisting, as
nearly as possible, of one-third of the total number of directors, with each
class having a three-year term. Vacancies on the Board may be filled only by
persons elected by a majority of the remaining directors. A director elected by
the Board to fill a vacancy (including a vacancy created by an increase in the
Board) will serve for the remainder of the full term of the class of directors
in which the vacancy occurred and until such director's successor is elected and
qualified.
 
     The Board is presently composed of eight members. There are two directors
in the class whose term of office expires in 1997. Each of the nominees for
election to this class is currently a director of the Company who was previously
elected by the stockholders. If elected at the Annual Meeting, each of the
nominees would serve until the 2000 Annual Meeting and until his successor is
elected and has qualified, or until such director's earlier death, resignation
or removal.
 
     Directors are elected by a plurality of the votes present in person or
represented by proxy and entitled to vote at the meeting. Shares represented by
executed proxies will be voted, if authority to do so is not withheld, for the
election of the two nominees named below. In the event that any nominee should
be unavailable for election as a result of an unexpected occurrence, such shares
will be voted for the election of such substitute nominee as management may
propose. Each person nominated for election has agreed to serve if elected, and
management has no reason to believe that any nominee will be unable to serve.
 
     Set forth below is biographical information for each person nominated and
each person whose term of office as a director will continue after the Annual
Meeting.

BOARD COMMITTEES AND MEETINGS
 
     During the fiscal year ended December 31, 1996, the Board held eight
meetings. The Board has an Audit Committee, a Compensation Committee and a
Non-Officer Stock Option Administration Committee. The Board does not have a
nominating committee nor any committee that functions as a nominating committee.
 
     The Audit Committee meets with the Company's independent auditors at least
annually to review the results of the annual audit and discuss the financial
statements, recommends to the Board the independent auditors to be retained, and
receives and considers the auditors' comments as to controls, adequacy of staff
and management performance and procedures in connection with audit and financial
controls. The Audit Committee is composed of two non-employee directors: Messrs.
Levert and Smelick. During fiscal 1996, the Audit Committee met two times.
 
     The Compensation Committee makes recommendations concerning salaries and
incentive compensation, awards stock options to employees and consultants under
the Company's stock option plans and otherwise determines compensation levels
and performs such other functions regarding compensation as the Board may
delegate. The Compensation Committee is currently composed of two non-employee
directors, Messrs. Bond and Cline. During fiscal 1996, the Compensation
Committee met five times.
 
     The Non-Officer Stock Option Administration Committee was established in
June 1992 to administer the Company's stock option plans only for non-officer
employees and to make stock option grants to such employees not in excess of
25,000 shares. All option grants in excess of this limit and all option grants
to officers must be approved by the Compensation Committee. The Non-Officer
Stock Option Administration Committee is composed of Mr. Dilworth, who is the
Chief Executive Officer and Chairman of the Board of Directors of the Company.
 
     During fiscal 1996, all directors except Mr. Bond attended at least 75% of
the aggregate of the meetings of the Board and of the committees on which they
served, held during the period for which they were a director or committee
member, respectively. Mr. Bond attended all meetings of the Compensation
Committee held during fiscal 1996; however, he was unable to attend one regular
meeting and two special meetings of the Board during fiscal 1996.
 
                                   PROPOSAL 2
 
                   APPROVAL OF THE 1997 EQUITY INCENTIVE PLAN
 
     In March 1997, the Board adopted, subject to stockholder approval, the 1997
Equity Incentive Plan (the "Incentive Plan"), and reserved 675,000 shares for
issuance under the Incentive Plan. The Board adopted the Incentive Plan to
ensure that the Company can continue to provide equity incentives to employees
at levels determined appropriate by the Board following termination of the
Company's 1988 Stock Option Plan, as amended (the "1988 Plan"), which terminates
on March 7, 1998. No stock options may be granted under the 1988 Plan after it
is terminated.
 
     No Stock Awards (as defined below) have been granted or issued under the
Incentive Plan. During the last fiscal year, under the 1988 Plan, the Company
has granted to all current executive officers as a group, including repriced
options, options to purchase 443,000 shares at exercise prices of $13.125 to
$13.50 per share, to all employees (excluding executive officers) as a group,
including repriced options, options to purchase 1,508,253 shares at exercise
prices of $10.75 to $19.31 per share and to all current directors who are not
officers as a group options to purchase 14,000 shares at exercise prices of
$14.6875 per share.
 
     Stockholders are requested in this Proposal to approve the Incentive Plan
and to reserve for issuance 675,000 shares. The affirmative vote of the holders
of a majority of the shares present in person or represented by proxy and
entitled to vote at the meeting will be required to approve the Incentive Plan.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 2
 
                                        4
<PAGE>   7
 
     The essential features of the Incentive Plan are outlined below:
 
GENERAL
 
     The Incentive Plan provides for the grant or issuance of incentive stock
options, nonstatutory stock options, restricted stock purchase awards and stock
bonuses (collectively, "Stock Awards") to employees, directors and consultants.
Incentive stock options granted under the Incentive Plan are intended to qualify
as "incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"). Nonstatutory stock options
granted under the Incentive Plan are intended not to qualify as incentive stock
options under the Code. See "Federal Income Tax Information" for a discussion of
the tax treatment of the various awards included in the Incentive Plan.
 
PURPOSE
 
     The Incentive Plan provides a means by which selected employees, directors
of and consultants to the Company, and its affiliates, may be given an
opportunity to purchase Common Stock of the Company. The Company, by means of
the Incentive Plan, seeks to retain the services of persons who are now
employees, directors or consultants to the Company or its affiliates, to secure
and retain the services of new employees, directors and consultants, and to
provide incentives for such persons to exert maximum efforts for the success of
the Company and its affiliates. Approximately 195 of the Company's approximately
250 employees are eligible to participate in the Incentive Plan.
 
ADMINISTRATION
 
     The Incentive Plan is administered by the Board unless and until the Board
delegates administration to a committee composed of one or more Board members,
all of the members of which committee may be non-employee directors (as defined
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) and
may also be, in the discretion of the Board, outside directors (as defined under
the Code). If administration is delegated to a committee, such committee will
have, in connection with the administration of the Incentive Plan, the powers
possessed by the Board, subject, however, to such resolutions, not inconsistent
with the provisions of the Incentive Plan, as may be adopted from time to time
by the Board. The Board or the committee may delegate to a subcommittee of one
or more members of the Board the authority to grant Stock Awards to eligible
persons who are not then subject to Section 16 of the Exchange Act and/or who
are either (i) not then employees covered by Section 162(m) of the Code and are
not expected to be covered by Section 162(m) of the Code at the time of
recognition of income resulting from such Stock Award, or (ii) not persons with
respect to whom the Company wishes to avoid the application of Section 162(m) of
the Code. The Board may abolish a committee or subcommittee at any time and
revest in the Board the administration of the Incentive Plan. The Board has
delegated the administration of the Incentive Plan to the Compensation Committee
and, to a limited extent, the Non-Officer Stock Option Administration Committee
of the Board. See "Proposal 1 -- Election of Directors -- Board Committees and
Meetings." As used herein, with respect to the 1988 Plan, the "Board" refers to
the Compensation Committee, and where applicable, the Non-Officer Stock Option
Administration Committee, as well as to the Board itself.
 
     The Board has the power to determine from time to time which of the persons
eligible under the Incentive Plan shall be granted awards, the type of awards to
be granted, when and how each award shall be granted, to construe and interpret
the Incentive Plan and awards granted under it, and to establish, amend and
revoke rules and regulations for its administration. The Board may correct any
defect in the Incentive Plan or in any award agreement to make the Incentive
Plan fully effective.
 
SHARES SUBJECT TO THE PLAN
 
     The Common Stock that may be sold pursuant to awards under the Incentive
Plan shall not exceed in the aggregate 675,000 shares of the Company's Common
Stock. If any award expires or terminates, in whole or in
 
                                        5
<PAGE>   8
 
part, without having been exercised in full, the stock not purchased under such
award will revert to and again become available for issuance under the Incentive
Plan. The Common Stock subject to the Incentive Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.
 
ELIGIBILITY
 
     Incentive stock options may be granted only to employees. Nonstatutory
stock options, restricted stock purchase awards and stock bonuses may be granted
only to employees, directors or consultants.
 
     No person is eligible for the grant of an incentive stock option if, at the
time of grant, such person owns stock possessing more than 10% of the total
combined voting power of all classes of stock of the Company unless the exercise
price of such option is at least 110% of the fair market value of such Common
Stock subject to the option at the date of grant and the option is not
exercisable after the expiration of five years from the date of grant, or in the
case of a restricted stock purchase award, the purchase price is at least 100%
of the fair market value of Common Stock subject to the award at date of grant.
No person shall be eligible to be granted Stock Awards covering more than
400,000 shares of the Company's Common Stock in any calendar year.
 
TERM AND TERMINATION
 
     No option is exercisable after the expiration of 10 years from the date it
was granted.
 
     In the event an optionee's continuous status as an employee, director or
consultant is terminated, the optionee may exercise his or her option (to the
extent that the optionee was entitled to exercise it at the time of termination)
but only within the earlier of (i) the date three months after the termination
of the optionee's continuous status as an employee, director or consultant, or
(ii) the expiration of the term of the option as set forth in the option
agreement.
 
     An optionee's option agreement may also provide that if the exercise of the
option following the termination of the optionee's continuous status as an
employee, director, or consultant would result in liability under Section 16(b)
of the Exchange Act, then the option shall terminate on the earlier of (i) the
expiration of the term of the option set forth in the option agreement, or (ii)
the 10th day after the last date on which such exercise would result in such
liability under Section 16(b) of the Exchange Act. Finally, an optionee's option
agreement may also provide that if the exercise of the option following the
termination of the optionee's continuous status as an employee, director or
consultant would be prohibited at any time solely because the issuance of shares
would violate the registration requirements under the Securities Act of 1933, as
amended (the "Securities Act") then the option shall terminate on the earlier of
(i) the expiration of the term of the option as set forth in the immediately
preceding paragraph, or (ii) the expiration of a period of three months after
the termination of the optionee's continuous status as an employee, director or
consultant during which the exercise of the option would not be in violation of
such registration requirements.
 
     In the event an optionee's continuous status as an employee, director or
consultant terminates as a result of the optionee's death or disability, the
optionee (or such optionee's estate, heirs or beneficiaries) may exercise his or
her option, but only within the period ending on the earlier of (i) 12 months
following such termination (or such longer or shorter period as specified in the
option agreement) or (ii) the expiration of the term of the option as set forth
in the option agreement.
 
     In the event a stock bonus or restricted stock recipient's continuous
status as an employee, director or consultant terminates, the Company may
repurchase or otherwise reacquire any or all of the shares of stock held by that
person which have not vested as of the date of termination under the terms of
the stock bonus or restricted stock purchase agreement between the Company and
such person.
 
EXERCISE/PURCHASE PRICE
 
     The exercise price of each incentive stock option will not be less than
100% of the fair market value of the Company's Common Stock on the date of
grant. The exercise price of each nonstatutory stock option will not be less
than 85% of the fair market value on the date of grant. The purchase price of
restricted stock will not be
 
                                        6
<PAGE>   9
 
less than 85% of the fair market value of the Company's Common Stock on the date
such award is made. Stock bonuses may be awarded in consideration for past
services actually rendered to the Company or for its benefit. At March 17, 1997,
the closing price of the Company's Common Stock as reported on the Nasdaq
National Market System was $11.125 per share.
 
CONSIDERATION
 
     The purchase price of stock acquired pursuant to a Stock Award is paid
either in cash at the time of exercise or purchase, or (if determined by the
Board at the time of grant for an option) by deferred payment or other
arrangement or in any other form of legal consideration that may be acceptable
to the Board. Additionally, in the case of an option and in the discretion of
the Board at the time of the grant of an option, by delivery to the Company of
other Common Stock of the Company. In the case of any deferred payment
arrangement, interest will be payable at least annually and will be charged at
the minimum rate of interest necessary to avoid the treatment as interest of
amounts that are not stated to be interest.
 
TRANSFERABILITY
 
     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 person to whom the incentive stock option is granted only by
such person. A stock bonus or restricted stock award shall not be transferable
except by will or by the laws of descent and distribution or pursuant to a
domestic relations order. A nonstatutory stock option shall be transferable only
to the extent specifically provided for in the option agreement evidencing the
nonstatutory stock option, provided that if the nonstatutory stock option
agreement does not provide for transferability, then the option is not
transferable except by will or by the laws of descent and distribution or
pursuant to a domestic relations order. An award holder may designate a
beneficiary who may exercise his or her award after death.
 
VESTING
 
     The total number of shares of stock subject to an option may, but need not,
be allotted in periodic installments. The option agreement may provide that from
time to time during each of such installment periods, the option may become
exercisable ("vest") with respect to some or all of the shares allotted to that
period, and may be exercised with respect to some or all of the shares allotted
to such period and/or any prior period as to which the option became vested but
was not fully exercised. The option agreement may also provide that an optionee
may exercise an option prior to full vesting, provided that the Company may have
a repurchase right with respect to any unvested shares.
 
     Restricted stock purchase awards and stock bonuses granted under the
Incentive Plan may be granted pursuant to a repurchase option in favor of the
Company in accordance with a vesting schedule determined by the Board.
 
ADJUSTMENTS UPON CHANGES IN STOCK
 
     If any change is made in the Common Stock subject to the Incentive Plan, or
subject to any Stock Award, without receipt of consideration by the Company
(through merger, consolidation, reorganization, recapitalization, stock
dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or otherwise), the class(es) and maximum number of shares subject to
the Incentive Plan, the maximum annual award applicable under the Incentive Plan
and the class(es) and number of shares and price per share of stock subject to
outstanding Stock Awards will be appropriately adjusted.
 
     In the event of a merger, consolidation, liquidation, dissolution or the
sale of substantially all of the Company's assets or a reverse merger in which
the Company is the surviving corporation but the shares of the Company's 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, any surviving corporation shall assume any Stock Awards outstanding
under the Incentive Plan or shall substitute similar awards for those
 
                                        7
<PAGE>   10
 
outstanding under the Incentive Plan or such Stock Awards shall continue in full
force and effect. In the event a surviving corporation refuses to assume such
Stock Awards or substitute similar awards, then, with respect to stock awards
held by persons then performing services as employees, directors or consultants,
the time during which such Stock Awards may be exercised shall be accelerated
prior to completion of such transaction and such Stock Awards terminated if not
exercised prior to such transaction. In addition, with respect to any person who
was providing services as an employee, director or consultant immediately prior
to such transaction, the time during which Stock Awards may be exercised shall
be accelerated and any repurchase right of the Company with respect to such
Stock Awards shall lapse if such person is terminated without cause within 12
months of such transaction. The acceleration of a Stock Award in the event of an
acquisition or similar corporate event may be viewed as an antitakeover
provision, which may have the effect of discouraging a proposal to acquire or
otherwise obtain control of the Company.
 
AMENDMENT OF THE INCENTIVE PLAN
 
     The Board at any time, and from time to time, may amend the Incentive Plan.
However, no amendment shall be effective unless approved by the stockholders of
the Company within 12 months before or after the adoption of the amendment,
where the amendment will increase the number of shares reserved for issuance
under the Incentive Plan, modify the requirements as to eligibility for
participation or in any other way if such modification requires stockholder
approval in order for the Incentive Plan to satisfy the requirements of Section
422 of the Code or to comply with the requirements of Rule 16b-3 of the Exchange
Act. The Board may in its sole discretion submit any other amendment to the
Incentive Plan for stockholder approval.
 
TERMINATION OR SUSPENSION OF THE INCENTIVE PLAN
 
     The Board may suspend or terminate the Incentive Plan at any time. Unless
sooner terminated, the Incentive Plan shall terminate in March 2007. No Stock
Awards may be granted under the Incentive Plan while the Incentive Plan is
suspended or after it is terminated.
 
FEDERAL INCOME TAX INFORMATION
 
     Incentive Stock Options. Incentive stock options under the Incentive Plan
are intended to be eligible for the favorable federal income tax treatment
accorded "incentive stock options" under the Code.
 
     There generally are no federal income tax consequences to the optionee or
the Company by reason of the grant or exercise of an incentive stock option.
However, the exercise of an incentive stock option may increase the optionee's
alternative minimum tax liability, if any.
 
     If an optionee holds stock acquired through exercise of an incentive stock
option for at least two years from the date on which the option is granted and
at least one year from the date on which the shares are transferred to the
optionee upon exercise of the option, any gain or loss on a disposition of such
stock will be long-term capital gain or loss. Generally, if the optionee
disposes of the stock before the expiration of either of these holding periods
(a "disqualifying disposition"), at the time of disposition, the optionee will
realize taxable ordinary income equal to the lesser of (a) the excess of the
stock's fair market value on the date of exercise over the exercise price, or
(b) the optionee's actual gain, if any, on the purchase and sale. The optionee's
additional gain, or any loss, upon the disqualifying disposition will be a
capital gain or loss, which will be long-term or short-term depending on whether
the stock was held for more than one year. Capital gains currently are generally
subject to lower tax rates than ordinary income. The maximum long-term capital
gains rate for federal income tax purposes is currently 28% while the maximum
ordinary income rate is effectively 39.6% at the present time. Slightly
different rules may apply to optionees who acquire stock subject to certain
repurchase options or who are subject to Section 16(b) of the Exchange Act.
 
     To the extent the optionee recognizes ordinary income by reason of a
disqualifying disposition, the Company will generally be entitled (subject to
the requirement of reasonableness and the satisfaction of a tax reporting
obligation) to a corresponding business expense deduction in the tax year in
which the disqualifying disposition occurs.
 
                                        8
<PAGE>   11
 
     Nonstatutory Stock Options. Nonstatutory stock options granted under the
Incentive Plan generally have the following federal income tax consequences:
 
     There are no tax consequences to the optionee or the Company by reason of
the grant of a nonstatutory stock option. Upon exercise of a nonstatutory stock
option, the optionee normally will recognize taxable ordinary income equal to
the excess of the stock's fair market value on the date of exercise over the
option exercise price. With respect to employees, the Company is generally
required to withhold from regular wages or supplemental wage payments an amount
based on the ordinary income recognized. Generally, the Company will generally
be entitled to a business expense deduction equal to the taxable ordinary income
realized by the optionee. Upon disposition of the stock, the optionee will
recognize a capital gain or loss equal to the difference between the selling
price and the sum of the amount paid for such stock plus any amount recognized
as ordinary income upon exercise of the option. Such gain or loss will be long
or short-term depending on whether the stock was held for more than one year.
Slightly different rules may apply to optionees who acquire stock subject to
certain repurchase options or who are subject to Section 16(b) of the Exchange
Act.
 
     Restricted Stock Purchase Awards and Stock Bonuses. Restricted stock
purchase awards and stock bonuses granted under the Incentive Plan generally
have the following federal income tax consequences:
 
     Upon acquisition of the stock, the recipient normally will recognize
taxable ordinary income equal to the excess of the stock's fair market value
over the purchase price, if any. However, to the extent the stock is subject to
certain types of vesting restrictions, the taxable event will be delayed until
the vesting restrictions lapse unless the recipient elects to be taxed on
receipt of the stock. With respect to employees, the Company is generally
required to withhold from regular wages or supplemental wage payments an amount
based on the ordinary income recognized. Generally, the Company will generally
be entitled to a business expense deduction equal to the taxable ordinary income
realized by the optionee. Upon disposition of the stock, the optionee will
recognize a capital gain or loss equal to the difference between the selling
price and the sum of the amount paid for such stock plus any amount recognized
as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss
will be long or short-term depending on whether the stock was held for more than
one year. Slightly different rules may apply to optionees who acquire stock
subject to certain repurchase options or who are subject to Section 16(b) of the
Exchange Act.
 
     Potential Limitation on Company Deductions. As part of the Omnibus Budget
Reconciliation Act of 1993, the U.S. Congress amended the Code to add Section
162(m) which denies a deduction to any publicly held corporation for
compensation paid to certain employees in a taxable year to the extent that
compensation exceeds $1 million for a covered employee. It is possible that
compensation attributable to awards granted in the future under the Incentive
Plan, when combined with all other types of compensation received by a covered
employee from the Company, may cause this limitation to be exceeded in any
particular year.
 
     Certain kinds of compensation, including qualified "performance-based
compensation," are disregarded for purposes of the deduction limitation. In
accordance with Treasury regulations issued under Section 162(m), compensation
attributable to stock options will qualify as performance-based compensation,
provided that the option is granted by a compensation committee comprised solely
of "outside directors" and either: (i) the option plan contains a per-employee
limitation on the number of shares for which options may be granted during a
specified period, the per-employee limitation is approved by the stockholders,
and the exercise price of the option is no less than the fair market value of
the stock on the date of grant; or (ii) the option is granted (or exercisable)
only upon the achievement (as certified in writing by the compensation
committee) of an objective performance goal established in writing by the
compensation committee while the outcome is substantially uncertain, and the
option is approved by stockholders.

                                   PROPOSAL 3
 
               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS
 
     The Board has selected Arthur Andersen LLP as the Company's independent
auditors for the fiscal year ending December 31, 1997 and has further directed
that management submit the selection of independent auditors for ratification by
the stockholders at the Annual Meeting. Arthur Andersen LLP has audited the
Company's financial statements since 1988. Representatives of Arthur Andersen
LLP are expected to be present at the Annual Meeting, will have an opportunity
to make a statement if they so desire and will be available to respond to
appropriate questions.
 
     Stockholder ratification of the selection of Arthur Andersen LLP as the
Company's independent auditors is not required by the Company's Bylaws or
otherwise. However, the Board is submitting the selection of Arthur Andersen LLP
to the stockholders for ratification as a matter of good corporate practice. If
the stockholders fail to ratify the selection, the Audit Committee and the Board
will reconsider whether or not to retain that firm. Even if the selection is
ratified, the Audit Committee and the Board in their discretion may direct the
appointment of a different firm as independent auditors at any time during the
year if they determine that such a change would be in the best interests of the
Company and its stockholders.
 
     The affirmative vote of the holders of a majority of the shares present in
person or represented by proxy and entitled to vote at the meeting will be
required to ratify the selection of Arthur Andersen LLP.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 3

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934 (the "1934 Act")
requires the Company's directors and executive officers, and persons who own
more than ten percent of a registered class of the Company's equity securities,
to file with the SEC initial reports of ownership and reports of changes in
ownership of Common Stock and other equity securities of the Company. Officers,
directors and greater than ten percent stockholders are required by SEC
regulation to furnish the Company with copies of all Section 16(a) forms they
file.
 
     To the Company's knowledge, based solely on a review of the copies of such
reports furnished to the Company and written representations that no other
reports were required, during fiscal 1996, all Section 16(a) filing requirements
applicable to its officers, directors and greater than ten percent beneficial
owners were complied with; except that one report covering two donations by Mr.
Smelick of a total of 3000 shares was not timely filed and in Mr. Jaschke's
initial report, although timely filed, 500 shares of Common Stock that had been
acquired by Mr. Jaschke prior to his becoming a director of the Company were
inadvertently omitted. These errors have been corrected by filing amendments to
the year-end Form 5 and the previously filed report, respectively.

                             EXECUTIVE COMPENSATION
 
DIRECTOR COMPENSATION
 
     Each non-employee director of the Company, except for Mr. Smelick, receives
an annual retainer of $6,000 and a per meeting fee of $1,000 (plus $250 for each
committee meeting attended by committee members). The members of the Board are
also eligible for reimbursement for their expenses incurred in connection with
attendance at Board and committee meetings in accordance with Company policy. In
fiscal 1996, the total compensation paid to non-employee directors as a group
was $41,500.
 
     Each non-employee director of the Company, except for Mr. Smelick, also
receives stock option grants under the 1993 Non-Employee Directors' Stock Option
Plan (the "Directors' Plan"). Only non-employee directors of the Company are
eligible to receive options under the Directors' Plan. Options granted under the
Directors' Plan are intended by the Company not to qualify as incentive stock
options under the Code.
 
     Option grants under the Directors' Plan are non-discretionary. In June
1996, the Board adopted, and in August 1996 the stockholders approved, an
amendment to the Directors' Plan to provide that on January 1 of each year (or
the next business day should such date be a legal holiday), each member of the
Board who is not an employee of the Company is automatically granted under the
Directors' Plan, without further action by the Company, the Board or the
stockholders of the Company, an option to purchase 7,000 shares of Common Stock
of the Company. No other options may be granted at any time under the Directors'
Plan. The exercise price of options granted under the Directors' Plan is 100% of
the fair market value of the Common Stock subject to the option on the date of
the option grant. Options granted under the Directors' Plan may not be exercised
until the date upon which such optionee has provided one year of continuous
service as a non-employee director following the date of grant of such option,
whereupon such option will become exercisable as to one third of the option
shares and one third of the option shares will become exercisable each year
thereafter in accordance with its terms. The term of options granted under the
Directors' Plan is ten years. In the event of a merger of the Company with or
into another corporation or a consolidation, acquisition of assets or other
change-in-control transaction involving the Company, the vesting of each option
will accelerate and the option will terminate if not exercised prior to the
consummation of the transaction.
 
     During the last fiscal year, the Company granted options under the
Directors' Plan covering 7,000 shares to each of Mr. Cline and Mr. Rumsfeld on
January 1, 1996 at an exercise price per share of $13.75 and to each of Mr.
Jaschke and Mr. Yang upon their election as directors in June 1996 at an
exercise price per share of $18.50. The fair market value of such Common Stock
on the date of grant was $13.75 per share and $18.50 per share, respectively
(based on the average of the previous day's high and low sales price reported in
the National Market System). As of December 31, 1996, options to purchase 14,000
shares of Common Stock had been exercised under the Directors' Plan.
 
     The Board also granted Mr. Yang an option covering 25,000 shares in June
1996 at an exercise price per share of $18.50. The fair market value of such
Common Stock on the date of grant was $18.50 per share. In addition, in November
1996, after stockholder approval of the Directors' Plan, as amended, the Board
granted options under the Company's 1988 Stock Option Plan to continuing
directors, who did not receive automatic grants under the Directors' Plan in
1996. Mr. Bond and Mr. Levert were each granted options covering 7,000 shares at
an exercise price per share of $14.6875. Such options may not be exercised for
at least one year from the date of grant and become exercisable as to two thirds
of the option shares on January 1, 1998 and one third of the option shares one
year thereafter. The fair market value of the Common Stock on the date of grant
was $14.6875 per share. All fair market values stated in this paragraph are
based on the average of the previous day's high and low sales price reported in
the Nasdaq National Market.
 
     Directors who are employees of the Company do not receive separate
compensation for their services as directors.

(1) Includes repriced options. All options with exercise prices of $13.125 are
    repriced options. See "Option Repricing Information."
 
(2) Options granted under the Company's 1988 Plan typically vest 25% after one
    year and approximately two percent per month thereafter, such that the
    options are fully vested in four years. The options will fully vest upon a
    change of control, as defined in the 1988 Plan, unless the acquiring company
    assumes the options or substitutes similar options.
 
(3) Based on an aggregate of options covering 969,000 shares granted in fiscal
    1996 and options covering 982,253 shares repriced in 1996 under the 1988
    Plan to employees of the Company, including the Named Executive Officers.
 
(4) For new grants, the potential realizable value is calculated based on the
    term of the option at its time of grant (10 years). For repriced options it
    is based on the length of the original term remaining at the time of
    repricing. See "Option Repricing Information." Potential realizable value is
    calculated by assuming that the stock price on the date of grant appreciates
    at the indicated annual rate compounded annually for the entire term of the
    option and that the option is exercised and sold on the last day of its term
    for the appreciated stock price. No gain to the optionee is possible unless
    the stock price increases over the option term, which will benefit all
    stockholders.

COMPENSATION COMMITTEE REPORT ON OPTION REPRICING
 
     In January 1996, after a steady decline in the market price of the Common
Stock, the Board of Directors implemented a Company-wide repricing program
pursuant to which all employees (including executive officers) and consultants
were offered the opportunity to have those of their stock options with exercise
prices greater than $14.00, which was above the then-market value of the Common
Stock, replaced with non-qualified stock options with an exercise price of
$13.125, the fair market value of the Common Stock on the effective date of the
repricing, and certain delayed vesting terms. The Board took this action because
it determined that the purpose of the Company's stock option program of
providing an equity incentive for optionees to remain in the employ of or
service to the Company and work diligently in its best interests would not be
achieved for optionees holding options exercisable above the market price,
particularly in light of the intense competition in the Company's industry for
talented employees, and that retaining the services of such employees was
absolutely critical in fostering the best interest of the Company and the
stockholders.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Company applies a consistent philosophy to compensation for all
employees, including senior management. It is based on the premise that
achievements of the Company result from the coordinated efforts of all
individuals workings toward common objectives focused on meeting customer and
stockholder expectations.
 
     The goals of the Company's compensation program are to align compensation
with business objectives and performance while enabling the Company to attract,
retain and reward employees who contribute to the long-term success of the
Company. In all cases, attention is given to fairness in the administration of
compensation and to assuring that all employees understand the related
performance evaluation and administrative process.
 
     The Company's compensation program for executive officers is based on the
principles described above and it is administered by the Compensation Committee.
For fiscal 1996, the Compensation Committee was composed of Mr. Cline, who is
Chairman of the Committee, and Mr. Bond, both non-employee directors of the
Company. There were no interlocking or other type of relationships affecting the
independence of the committee members during fiscal 1996.
 
     The Company's executive compensation is intended to be consistent with
leading companies in the electronics and communications industries while being
contingent upon the Company's achievement of near-and long-term objectives and
goals. For fiscal 1996, the principal measures the Compensation Committee looked
to in evaluating the Company's progress towards these objectives and goals were
(1) efforts to attract Ricochet subscribers to target numbers, and (2) to raise
sufficient capital to sustain and continue operations. Other management
objectives considered by the Compensation Committee included installing Ricochet
networks in three MSAs, providing technology to meet market needs and
implementing the Company's real estate plan. The Company's executive
compensation is based on four components, each of which is intended to serve the
overall compensation philosophy.
 
  BASE SALARY
 
     Base salary is targeted toward the middle of the range established by
comparable companies in the electronics and communications industries. Base
salaries are reviewed annually to ensure that the Company's salaries are
competitive within the target range. For the purpose of establishing these
levels for fiscal 1996, the
 
                                       17
<PAGE>   20
 
Company relied in part on American Electronics Association salary surveys, on a
survey conducted by a nationally recognized compensation consultant of
U.S.-based high technology companies and on data obtained from executive search
firms that place executives with Silicon Valley companies. The composition of
each of the comparison groups in these surveys and data sources varies from the
sample represented in the industry index contained in the Performance
Measurement Comparison. The salary adjustments for the Named Executive Officers
shown in the Summary Compensation Table from fiscal 1994 to fiscal 1995 were
primarily designed to bring these salaries into closer alignment with the
mid-range of comparable companies. The Company has been increasing executive
salaries gradually from a level that was significantly below the targeted range.
Recognizing the competitive environment in the Company's industry and in the
Silicon Valley area generally, the increases approved by the Compensation
Committee in 1996 were intended to keep salaries in the mid-range of targeted
companies in order to retain valuable employees.
 
  MERIT INCREASE
 
     Merit increases are designed to encourage management to perform at
consistently high levels. Salaries for executives are reviewed by the
Compensation Committee on an annual basis and may be increased at that time
based on the Compensation Committee's agreement that the individual's overall
contribution to the Company merits recognition. The salary adjustments reflected
in the Summary Compensation Table were also affected, in the case of executive
officers other than the Chief Executive Officer, by the evaluation of individual
contributions to the Company as provided to the Compensation Committee by the
Chief Executive Officer.
 
  BONUSES
 
     Bonuses for executives are intended to be used as an incentive to encourage
management to perform at a high level or to recognize a particular contribution
by an employee or exceptional Company performance. Generally, the higher the
employee's level of job responsibility, the larger the portion of the
individual's compensation package that may be represented by a bonus. Whether a
bonus will be given, and the amount of any such bonus, is determined on a yearly
basis. Bonus awards must be approved by the Chief Executive Officer and the
Compensation Committee in the case of executives other than the Chief Executive
Officer and by the Compensation Committee alone in the case of the Chief
Executive Officer.
 
     In determining the bonus element of compensation, the Compensation
Committee places particular emphasis on the Company's performance against the
management objectives and goals described above. The Compensation Committee
evaluated the Company's performance against these objectives as follows: In
fiscal 1996, the Company made substantial progress in attracting new
subscribers, exceeding the target number of 6000 by 50% and in raising capital,
completing a private placement of $45 million of convertible subordinated notes
(before deducting expenses). The Company also made substantial progress in
developing and deploying Ricochet networks. By the end of fiscal 1996, the
Company had over 9,000 subscribers, had deployed fully operational Ricochet
networks over most of the San Francisco Bay Area and portions of Seattle,
Washington and Washington, D.C. and had made significant progress in acquiring
real estate in other metropolitan areas. In light of the Company's success in
achieving important objectives in fiscal 1996, the Compensation Committee
decided to award bonuses to executives.
 
     In addition to the bonuses described above, certain employees engaged in
sales and marketing receive commissions based on the results of their efforts.
 
  STOCK OPTIONS
 
     The Compensation Committee believes that stock ownership by management is
beneficial in aligning management and stockholder interests with respect to
enhancing stockholder value. Stock options are also used to retain executives
and motivate them to improve long-term stock market performance. Stock options
are granted at the prevailing market value and will only have value if the
Company's stock price increases. Generally, stock option grants vest 25% after
the first year and thereafter monthly in 36 equal amounts over three years.
 
                                       18
<PAGE>   21
 
     The Compensation Committee determines the number of options to be granted
based upon the competitive marketplace, with a particular focus on determining
what level of equity incentive is necessary to retain a particular individual.
Outstanding historical performance by an individual is additionally recognized
through larger than normal option grants.
 
  CHIEF EXECUTIVE OFFICER
 
     The Compensation Committee uses the same philosophy described above with
respect to other executive officers in setting the compensation for the Chief
Executive Officer, Mr. Dilworth. Recognizing that Mr. Dilworth's base salary had
been set for fiscal 1994, and after an increase in 1995 remained, at a level
below the average salary of comparable executives at the companies covered by
the surveys and other data described above, the Compensation Committee approved
an increase in salary for Mr. Dilworth to $305,000 in fiscal 1996. Based upon
the same factors considered with respect to the awarding of bonuses to
executives in the Company generally, the Compensation Committee awarded Mr.
Dilworth a bonus of $305,000 for fiscal 1996 (compared to a bonus of $137,500
for fiscal 1995). Mr. Dilworth was also granted options to purchase an aggregate
of 50,000 shares of Common Stock in fiscal 1996, based upon the Compensation
Committee's view of the equity incentive level required to retain his services
in a competitive market, as well as the Compensation Committee's desire to
maintain a clear alignment of management and stockholder interests.
 
  SECTION 162(m)
 
     Section 162(m) of the Code limits the Company to a deduction for federal
income tax purposes of no more than $1 million of compensation paid to certain
Named Executive Officers in a taxable year. Compensation above $1 million may be
deducted if it is "performance-based compensation" within the meaning of the
Code. The Compensation Committee has determined that stock options granted under
the Company's 1988 Stock Option Plan with an exercise price at least equal to
the fair market value of the Company's common stock on the date of grant will be
treated as "performance-based compensation." As a result, the Company's
stockholders were asked to approve, and did approve in May 1995, an amendment to
such plan that allows any compensation recognized by a Named Executive Officer
as a result of the grant of such a stock option to be deductible by the Company.

                              CERTAIN TRANSACTIONS
 
LOANS TO EXECUTIVE OFFICERS
 
     In October 1992, in connection with his relocation to California, the
Company provided Mr. Green, an executive officer of the Company, with a loan in
the amount of $150,000. This loan was secured by a lien on the property
purchased by Mr. Green and 25% of any vested shares of the Company's Common
Stock held by Mr. Green, was evidenced by a promissory note, bore interest at a
rate of 4.02% per annum and was repayable in five annual installments of $30,000
plus accrued interest beginning in December 1992. Mr. Green received an annual
bonus of $30,000 to be applied against the principal of the loan plus accrued
interest so long as he was employed by the Company at his current or a higher
position. As of the end of fiscal 1996, the Company had forgiven all of the
principal on the loan.
 
AGREEMENTS WITH STERLING PAYOT
 
     Mr. Smelick, a director of the Company, is Managing Principal, director and
stockholder of Sterling Payot Company ("Sterling Payot"). In October 1994, the
Company entered into an agreement with Sterling Payot, superseding an agreement
that had been entered into between the Company and Sterling Payot in February
1993. The new agreement provided for Sterling Payot to provide advisory services
over a three-year period commencing July 1, 1994 relating to strategic and
financing issues facing the Company, including the establishment of
international and domestic joint ventures, strategic alliances and similar
business arrangements and assistance with FCC and international licensing of
radio frequencies and related financing matters. Under the agreement, Sterling
Payot receives cash compensation of $150,000 per year plus expenses. The
aggregate amount paid to Sterling Payot in fiscal 1996 under the advisory
services agreement was $150,000 plus expenses. In January 1997, the Company
entered into an agreement with Sterling Payot, which extends the term of such
arrangement until the end of 1997 and sets the amount to be paid to Sterling
Payot for services provided in 1997 at $200,000 plus expenses.
 
     As compensation for investment banking services involving the establishment
of joint ventures, strategic alliances and similar business arrangements,
Sterling Payot received a warrant, which, as amended, is exercisable through
September 1998, to purchase 200,000 shares of the Company's Common Stock at an
exercise price of $13.75 per share. The warrant was subsequently transferred to
Sterling Payot Capital, L.P. The Company had the right to repurchase 100,000 of
the shares of Common Stock underlying the warrant, at a price of $.01 per
underlying share, if the Company did not enter into at least one significant
joint venture, strategic partner arrangement or similar business arrangement
prior to February 29, 1996. The Company entered into such an arrangement in
early 1996. Under the terms of the warrant, the Company has the right to
repurchase the other 100,000 shares of Common Stock underlying the warrant. The
Company's right to repurchase such shares expires on March 31, 1997. The Company
has agreed to register the resale of the shares underlying the warrant under the
Securities Act on a Form S-3 registration statement upon request after the first
exercise of the warrant.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Bylaws provide that the Company will indemnify its directors
and executive officers and may indemnify its other officers, employees and other
agents to the fullest extent permitted by Delaware law. The Company is also
empowered under its Bylaws to enter into indemnification contracts with its
directors and officers and to purchase insurance on behalf of any person whom it
is required or permitted to indemnify. Pursuant to these provisions, the Company
has entered into indemnity agreements with each of its directors and officers
and has obtained director and officer liability insurance.
 
     In addition, the Amended Certificate provides that, to the fullest extent
permitted by Delaware law, the Company's directors will not be liable for
monetary damages for breach of the directors' fiduciary duty of care to the
Company and its stockholders. This provision in the Amended Certificate does not
eliminate the duty of care and, in appropriate circumstances, equitable remedies
such as an injunction or other forms of non-monetary relief would remain
available under Delaware law. In addition, each director will continue to be
 
                                       21
<PAGE>   24
 
subject to liability for breach of the director's duty of loyalty to the
Company, for acts or omissions not in good faith or involving intentional
misconduct or knowing violations of law, for acts or omissions that the director
believes to be contrary to the best interests of the Company or its
stockholders, for any transaction from which the director derived an improper
personal benefit and for improper distributions to stockholders and improper
loans to directors and officers. This provision also does not affect a
director's responsibilities under any other laws, such as the federal securities
laws or state or federal environmental laws.

         (t)     "PLAN" means this 1997 Equity Incentive Plan.

         (u)     "RULE 16B-3" means Rule 16b-3 of the Exchange Act or any

         (v)     "STOCK AWARD" means any right granted under the Plan,

the Board delegates administration to a Committee, as provided in subsection
3(c).

         (b)     The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:





                                       3.
<PAGE>   28
                 (1)      To determine from time to time which of the persons
eligible under the Plan shall be granted Stock Awards; when and how each Stock
Award shall be granted; whether a Stock Award will be an Incentive Stock
Option, a Nonstatutory Stock Option, a stock bonus, a right to purchase
restricted stock, or a combination of the foregoing; the provisions of each
Stock Award granted (which need not be identical), including the time or times
when a person shall be permitted to receive stock pursuant to a Stock Award;
and the number of shares with respect to which a Stock Award shall be granted
to each such person.

                 (2)      To construe and interpret the Plan and Stock Awards
granted under it, and to establish, amend and revoke rules and regulations for
its administration.  The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

                 (3)      To amend the Plan or a Stock Award as provided in
                          Section 13.

                 (4)      Generally, to exercise such powers and to perform
such acts as the Board deems necessary or expedient to promote the best
interests of the Company which are not in conflict with the provisions of the
Plan.

         (c)     The Board may delegate administration of the Plan to a
committee or committees ("Committee") of one (1) or more members of the Board.
In the discretion of the Board, a Committee may consist solely of two (2) or
more Outside Directors, in accordance with Code Section 162(m), or solely of
two (2) or more Non-Employee Directors, in accordance with Rule 16b-3.  If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore
possessed by the Board, including the power to delegate to a subcommittee any
of the administrative powers the Committee is authorized to exercise (and
references in this Plan to the Board shall thereafter be to the Committee or
such a subcommittee), subject, however, to such resolutions, not inconsistent
with the provisions of the Plan, as may be adopted from time to time by the
Board.  The Board may abolish the Committee at any time and revest in the Board
the administration of the Plan.

4.       SHARES SUBJECT TO THE PLAN.

         (a)     Subject to the provisions of Section 12 relating to
adjustments upon changes in stock, the stock that may be issued pursuant to
Stock Awards shall not exceed in the aggregate six hundred seventy-five
thousand (675,000) shares of Common Stock.  If any Stock Award shall for any
reason expire or otherwise terminate, in whole or in part, without having been
exercised in full (or vested in the case of Restricted Stock), the stock not
acquired under such Stock Award shall revert to and again become available for
issuance under the Plan.

         (b)     The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.





                                       4.
<PAGE>   29
5.       ELIGIBILITY.

         (a)     Incentive Stock Options may be granted only to Employees.
Stock Awards other than Incentive Stock Options may be granted only to
Employees, Directors or Consultants.

         (b)     No person shall be eligible for the grant of an Incentive
Stock Option if, at the time of grant, such person owns (or is deemed to own
pursuant to Section 424(d) of the Code) stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the Company
or of any of its Affiliates unless the exercise price of such Option is at
least one hundred ten percent (110%) of the Fair Market Value of such stock at
the date of grant and the Option is not exercisable after the expiration of
five (5) years from the date of grant.

         (c)     Subject to the provisions of Section 12 relating to
adjustments upon changes in stock, no person shall be eligible to be granted
Stock Awards covering more than four hundred thousand (400,000) shares of
Common Stock in any calendar year.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  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.  No Option shall be exercisable after the expiration of
ten (10) years from the date it was granted.

         (b)     PRICE.  The exercise price of each Incentive Stock Option
shall be not less than one hundred percent (100%) of the Fair Market Value of
the stock subject to the Option on the date the Option is granted, and the
exercise price of each Nonstatutory Stock Option shall be not less than
eighty-five percent (85%) of the Fair Market Value of the stock subject to the
Option on the date the Option is granted.  Notwithstanding the foregoing, an
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)     CONSIDERATION.  The purchase price of 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 or Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other Common Stock of the Company,
(B) according to a deferred payment or other arrangement (which may include,
without limiting the generality of the foregoing, the use of other Common Stock
of the Company) with the person to whom the Option is granted or to whom the
Option is transferred pursuant to subsection 6(d), or (C) in any other form of
legal consideration that may be acceptable to the Board.  In the case of any
deferred payment arrangement, interest shall be payable at least annually and
shall be charged at the minimum rate of interest necessary to avoid





                                       5.
<PAGE>   30
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.

         (d)     TRANSFERABILITY.  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 person to whom the Incentive
Stock Option is granted only by such person.  A Nonstatutory Stock Option may
be transferred to the extent provided in the Option Agreement; provided that if
the Option Agreement does not expressly permit the transfer of a Nonstatutory
Stock Option, the Nonstatutory Stock Option shall not be transferable except by
will, by the laws of descent and distribution or pursuant to a domestic
relations order satisfying the requirements of Rule 16b-3, and shall be
exercisable during the lifetime of the person to whom the Option is granted
only by such person or any transferee pursuant to a domestic relations order.
Notwithstanding the foregoing, the person to whom the Option is granted 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
Optionee, shall thereafter be entitled to exercise the Option.

         (e)     VESTING.  The total number of shares of stock subject to an
Option may, but need not, be allotted in periodic installments (which may, but
need not, be equal).  The Option Agreement may provide that from time to time
during each of such installment periods, the Option may become exercisable
("vest") with respect to some or all of the shares allotted to that period, and
may be exercised with respect to some or all of the shares allotted to such
period and/or any prior period as to which the Option became vested but was not
fully exercised.  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
provisions of this subsection 6(e) are subject to any Option provisions
governing the minimum number of shares as to which an Option may be exercised.

         (f)     TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT.  In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option within such period of
time designated by the Board, which shall in no event be later than the
expiration of the term of the Option as set forth in the Option Agreement (the
"Post-Termination Exercise Period") and only to the extent that the Optionee
was entitled to exercise the Option on the date Optionee's Continuous Status as
an Employee, Director or Consultant terminates. In the case of an Incentive
Stock Option, the Board shall determine the Post-Termination Exercise Period at
the time the Option is granted, and the term of such Post-Termination Exercise
Period shall in no event exceed three (3) months from the date of termination,
and may, in the event Optionee's Continuous Status as an Employee, Director or
Consultant terminates for Cause (as defined in subsection 12(b)), terminate of
the date of such Optionee's termination.  In addition, the Board may at any
time, with the consent of the Optionee, extend the Post-Termination Exercise
Period and provide for continued vesting; provided however, that any extension
of such period by the Board in excess of three (3) months from the date of
termination shall cause an Incentive Stock Option so extended to become a
Nonstatutory Stock Option, effective as of the date of Board action.  If, at
the date of termination, the Optionee is not entitled to exercise his or her
entire Option, the shares covered by the unexercisable portion of the Option
shall revert to the Plan.  If, after termination, the Optionee does not
exercise his





                                       6.
<PAGE>   31
or her Option within the time specified in the Option Agreement or as otherwise
determined above, the Option shall terminate, and the shares covered by such
Option shall revert to the Plan.  Notwithstanding the foregoing, the Board
shall have the power to permit an Option to continue to vest during the
Post-Termination Exercise Period.

         An Optionee's Option Agreement may also provide that if the exercise
of the Option following the termination of the Optionee's Continuous Status as
an Employee, Director, or Consultant (other than upon the Optionee's death or
disability) would result in liability under Section 16(b) of the Exchange Act,
then the Option shall terminate on the earlier of (i) the expiration of the
term of the Option set forth in the Option Agreement, or (ii) the tenth (10th)
day after the last date on which such exercise would result in such liability
under Section 16(b) of the Exchange Act.  Finally, an Optionee's Option
Agreement may also provide that if the exercise of the Option following the
termination of the Optionee's Continuous Status as an Employee, Director or
Consultant (other than upon the Optionee'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 Option shall
terminate on the earlier of (i) the expiration of the term of the Option set
forth in the first paragraph of this subsection 6(f), or (ii) the expiration of
a period of three (3) months after the termination of the Optionee's Continuous
Status as an Employee, Director or Consultant during which the exercise of the
Option would not be in violation of such registration requirements.

         (g)     DISABILITY OF OPTIONEE.  In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it at 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), or (ii) the expiration of
the term of the Option as set forth in the Option Agreement.  If, at the date
of termination, the Optionee is not entitled to exercise his or her entire
Option, the shares covered by the unexercisable portion of the Option shall
revert to and again become available for issuance under the Plan.  If, after
termination, the Optionee does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the shares covered by such
Option shall revert to and again become available for issuance under the Plan.

         (h)     DEATH OF OPTIONEE.  In the event of the death of an Optionee
during, or within a three (3)-month period after the termination of, the
Optionee's Continuous Status as an Employee, Director or Consultant, the Option
may be exercised to the extent vested by the Optionee'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 Optionee's death pursuant to
subsection 6(d), but only within the period ending on the earlier of (i) the
date eighteen (18) months following the date of death (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of
the term of such Option as set forth in the Option Agreement.  If, at the time
of death, the Optionee was not entitled to exercise his or her entire Option,
the shares covered by the unexercisable portion of the Option shall revert to
and again become available for issuance under the Plan.  If, after death, the
Option is not exercised within





                                       7.
<PAGE>   32
the time specified herein, the Option shall terminate, and the shares covered
by such Option shall revert to and again become available for issuance under
the Plan.

         (i)     EARLY EXERCISE.  The Option may, but need not, include a
provision whereby the Optionee may elect at any time while an Employee,
Director or Consultant to exercise the Option as to any part or all of the
shares subject to the Option prior to the full vesting of the Option.  Any
unvested shares so purchased may be subject to a repurchase right in favor of
the Company or to any other restriction the Board determines to be appropriate.

         (j)     RE-LOAD OPTIONS.  Without in any way limiting the authority of
the Board or Committee to make or not to make grants of Options hereunder, the
Board or Committee shall have the authority (but not an obligation) to include
as part of any Option Agreement a provision entitling the Optionee to a further
Option (a "Re-Load Option") in the event the Optionee 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.  Any such Re-Load Option (i) shall be for a
number of shares equal to the number of shares surrendered as part or all of
the exercise price of such Option; (ii) shall 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 (iii) shall 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 which is an Incentive Stock
Option and which is granted to a 10% stockholder (as described in subsection
5(b)), shall have an exercise price which is equal to one hundred ten percent
(110%) of the Fair Market Value of the stock subject to the Re-Load Option on
the date of exercise of the original Option and shall have a term which is no
longer than five (5) years.

         Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board or Committee 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 dollars ($100,000) annual limitation on exercisability of
Incentive Stock Options described in subsection 11(d) of the Plan 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 under subsection 4(a) and shall be subject to such other
terms and conditions as the Board or Committee may determine which are not
inconsistent with the express provisions of the Plan regarding the terms of
Options.

7.       TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board or Committee
shall deem appropriate.  The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus
or 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 as appropriate:





                                       8.
<PAGE>   33
         (a)     PURCHASE PRICE.  The purchase price under each restricted
stock purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value
on the date such award is made.  Notwithstanding the foregoing, the Board or
Committee may determine that eligible participants in the Plan may be awarded
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company for its benefit.

         (b)     TRANSFERABILITY.  No rights under a stock bonus or restricted
stock purchase agreement shall be transferable except by will or the laws of
descent and distribution or, if the agreement so provides, pursuant to a
domestic relations order satisfying the requirements of Rule 16b-3, so long as
stock awarded under such agreement remains subject to the terms of the
agreement.

         (c)     CONSIDERATION.  The purchase price of stock acquired pursuant
to a stock purchase agreement shall be paid either:  (i) in cash at the time of
purchase; (ii) at the discretion of the Board or Committee, according to a
deferred payment or other arrangement with the person to whom the stock is
sold; or (iii) in any other form of legal consideration that may be acceptable
to the Board or Committee in its discretion.  Notwithstanding the foregoing,
the Board or Committee to which administration of the Plan has been delegated
may award stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit.

         (d)     VESTING.  Shares of stock sold or awarded under the Plan may,
but need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or Committee.

         (e)     TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT.  In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.

8.       CANCELLATION AND RE-GRANT OF OPTIONS.

         (a)     The Board or Committee shall have the authority to effect, at
any time and from time to time,  (i) the repricing of any outstanding Options
under the Plan and/or (ii) with the consent of any adversely affected holders
of Options, the cancellation of any outstanding Options under the Plan and the
grant in substitution therefor of new Options under the Plan covering the same
or different numbers of shares of stock, but having an exercise price per share
not less than:  eighty-five percent (85%) of the Fair Market Value for a
Nonstatutory Stock Option, one hundred percent (100%) of the Fair Market Value
in the case of an Incentive Stock Option or, in the case of an Incentive Stock
Option held by a 10% stockholder (as described in subsection 5(b)), not less
than one hundred ten percent (110%) of the Fair Market Value per share of stock
on the new grant date.  Notwithstanding the foregoing, the Board or Committee
may grant an





                                       9.
<PAGE>   34
Option with an exercise price lower than that set forth above if such Option is
granted as part of a transaction to which section 424(a) of the Code applies.

         (b)     Shares subject to an Option canceled under this Section 8
shall continue to be counted against the maximum award of Options permitted to
be granted pursuant to the Plan.  The repricing of an Option hereunder
resulting in a reduction of the exercise price, shall be deemed to be a
cancellation of the original Option and the grant of a substitute Option; in
the event of such repricing, both the original and the substituted Options
shall be counted against the maximum awards of Options permitted to be granted
pursuant to the Plan, to the extent required by Section 162(m) of the Code.

9.       COVENANTS OF THE COMPANY.

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

         (b)     The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be
required to issue and sell shares under Stock Awards; provided, however, that
this undertaking shall not require the Company to register under the Securities
Act of 1933, as amended (the "Securities Act") either the Plan, any Stock Award
or any 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 stock under the Plan, the Company
shall be relieved from any liability for failure to issue and sell 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 stock pursuant to Stock Awards shall
constitute general funds of the Company.

11.      MISCELLANEOUS.

         (a)     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, 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)     Neither an Employee, Director nor a Consultant nor any person
to whom a Stock Award is transferred in accordance with the Plan shall be
deemed to be the holder of, or to have any of the rights of a holder with
respect to, any shares subject to such Stock Award unless and until such person
has satisfied all requirements for exercise of the Stock Award pursuant to its
terms.





                                      10.
<PAGE>   35
         (c)     Nothing in the Plan or any instrument executed or Stock Award
granted pursuant thereto shall confer upon any Employee, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or
any Affiliate, or to continue serving as a Consultant and Director, or shall
affect the right of the Company or any Affiliate to terminate the employment of
any Employee with or without notice and with or without cause, or the right to
terminate the relationship of any Consultant pursuant to the terms of such
Consultant's agreement with the Company or Affiliate or service as a Director
pursuant to the Company's By-Laws.

         (d)     To the extent that the aggregate Fair Market Value (determined
at the time of grant) of stock with respect to which Incentive Stock Options
are exercisable for the first time by any Optionee 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)     The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred in accordance with
the Plan, as a condition of exercising or acquiring stock under any Stock
Award, (1) to give written assurances satisfactory to the Company as to such
person'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 (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account
and not with any present intention of selling or otherwise distributing the
stock.  The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (i) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered
under a then currently effective registration statement under the Securities
Act, or (ii) 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 stock.

         (f)     To the extent provided by the terms of a Stock Award
Agreement, the person to whom a Stock Award is granted may satisfy any federal,
state or local tax withholding obligation relating to the exercise or
acquisition of stock under a Stock Award by any of the following means or by a
combination of such means:  (1) tendering a cash payment; (2) authorizing the
Company to withhold shares from the shares of the Common Stock otherwise
issuable to the participant as a result of the exercise or acquisition of stock
under the Stock Award; or (3) delivering to the Company owned and unencumbered
shares of the Common Stock of the Company.





                                      11.
<PAGE>   36
12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a)     If any change is made in the 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 shares subject to the Plan and the maximum
number of shares subject to award to any person during any calendar year, and
the outstanding Stock Awards will be appropriately adjusted in the class(es)
and number of shares and price per share of stock subject to such outstanding
Stock Awards.  Such adjustments shall be made by the Board or Committee, the
determination of which shall be final, binding and conclusive.  (The conversion
of any convertible securities of the Company shall not be treated as a
"transaction not involving the receipt of consideration by the Company.")

         (b)     In the event of a Change in Control, (i) any surviving or
acquiring corporation shall assume Stock Awards outstanding under the Plan or

granted and (ii) such person consents in writing.

         (e)     The Board at any time, and from time to time, may amend the
