                                  JUNE 7, 1999
 
                 INFORMATION CONCERNING SOLICITATION AND VOTING
 
GENERAL
 
    The enclosed proxy is solicited on behalf of the Board of Directors (the
"Board") of GateField Corporation, a Delaware corporation (the "Company"), for
use at the Annual Meeting of Stockholders to be held on June 7, 1999 at 1:00
p.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 47100 Bayside Parkway,
Fremont, California 94538. The Company intends to mail this proxy statement and
accompanying proxy card on or about April 30, 1999, 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
accompanying proxy card 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 regular
employees of the Company or, at the Company's request, Beacon Hill Partners,
Inc. No additional compensation will be paid to directors, officers or other
regular employees for such services, but Beacon Hill Partners, Inc. would be
paid its customary fee, estimated to be about $6,500, if it renders solicitation
services.
 
VOTING RIGHTS AND OUTSTANDING SHARES
 
    Only holders of record of Common Stock and Preferred Stock at the close of
business on April 8, 1999 will be entitled to notice of and to vote at the
Annual Meeting. At the close of business on April 8, 1999, the Company had
outstanding and entitled to vote (i) 41,545,531 shares of Common Stock, (ii)
18,003 shares of Series B Preferred Stock (the "Series B Stock") (convertible
into 82,498 shares of Common Stock) and (iii) 300,000 shares of Series C
Preferred Stock (the "Series C Stock") (convertible into 2,000,000 shares of
Common Stock) (collectively, the "Preferred 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. Each holder of record
of Preferred Stock on such date will be entitled to the number of votes equal to
the number of whole shares of Common Stock into which the shares of Preferred
Stock held by such holder are then convertible. However, as discussed below, in
connection with the election of directors of the Company pursuant to Proposal 1,
Stockholders will be permitted to exercise cumulative voting.
 
    All votes will be tabulated by the inspector of election 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. Except for Proposals 4 and 5, broker
non-votes are counted towards a quorum, but are not counted for any purpose in
determining whether a matter has been approved. With respect to Proposals 4 and
5, broker non-votes will have the same effect as negative votes.
<PAGE>
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, 47100
Bayside Parkway, Fremont, California 94538, 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
 
    The deadline for submitting a Stockholder proposal for inclusion in the
Company's proxy statement and form of proxy for the Company's 2000 Annual
Meeting of Stockholders pursuant to Rule 14a-8, of the Securities and Exchange
Commission is January 3, 2000. Unless a Stockholder who wishes to bring a matter
before the Stockholders at the Company's 2000 Annual Meeting notifies the
Company of such matter prior to March 17, 2000, management will have
discretionary authority to vote all shares for which it has proxies in
opposition to such matter.

                                   PROPOSAL 1
                             ELECTION OF DIRECTORS
 
    With respect to the election of directors, the Board has divided the
nominees into two slates, one for election in accordance with the Delaware
General Corporation Law ("Delaware Law") and the Company's Certificate and the
other for election in accordance with the California General Corporation Law
("California Law"). All holders of record of Common Stock and Preferred Stock at
the close of business on April 8, 1999 will be entitled to vote on each slate.
Each holder of Preferred Stock will be entitled to vote on an as-if converted
basis as described above.
 
    In connection with the vote on the first slate (the "First Slate"), each
holder of record of Common Stock and Preferred Stock on April 8, 1999 will be
entitled to vote for one director whose terms of office expires in 1999 (the
"Class II Nominee") to hold office until the 2002 annual meeting of
Stockholders. Further, in connection with the First Slate, each holder of Common
Stock and Preferred Stock will be entitled to one vote for each share of Common
Stock held and each whole share of Common Stock issuable upon conversion of each
share of Preferred Stock held.
 
    In connection with the vote on the second slate (the "Second Slate"),
Stockholders will be voting to elect all three current directors to hold office
until the next annual meeting of Stockholders. Further in connection with the
Second Slate, each holder of Common Stock will be entitled to three votes for
each share held.
 
    The slates are as follows:

</TABLE>
 
    Should the elections yield different results, the Company plans to seek
guidance from a court of law regarding which state's law the Company must apply
in its corporate governance matters.
 
FIRST SLATE: ELECTION OF DIRECTORS PURSUANT TO DELAWARE LAW
 
    The Company's Certificate and By-laws provide that the Board shall be
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 size of the Board) shall
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.
 
    Effective March 9, 1999, Messrs. Dunn and Huberman submitted their
resignations as directors of the Company. As a result, the Board of Directors is
presently composed of three members, one of whom is a Class I director (with a
term expiring at the 2001 annual meeting), one of whom is a Class II director
(with a term expiring at the 1999 Annual Meeting) and one of whom is a Class III
director (with a term expiring at the 2000 annual meeting). Following the
resignations of Messrs. Dunn and Huberman and because of the Company's desire to
give the Stockholders the opportunity to approve the election of Mr. Kucha to
the Board during 1999, the Board of Directors designated Messrs. Kucha and
Sandfort to new classes. As a result of such action, Mr. Kucha was designated as
a Class II director and Mr. Sandfort as a Class III director. Mr. Saxe shall
continue as a Class I director. As a result of these changes, Stockholders will
have the opportunity at the 1999 Annual Meeting to vote on the election of
Michael J. Kucha, as the Class II Nominee. The information presented herein
gives effect to these changes. The Class II Nominee is
 
                                       1
<PAGE>
currently a director of the Company who was previously elected by the Board of
Directors. If elected at the 1999 Annual Meeting, the Class II Nominee would
serve until the 2002 annual meeting of Stockholders 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 Class II Nominee. In the event that the 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. The person nominated for election has agreed to serve if elected, and
management has no reason to believe that such nominee will be unable to serve.
 
   THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF THE CLASS II NOMINEE
 
SECOND SLATE: ELECTION OF DIRECTORS PURSUANT TO CALIFORNIA LAW
 
    Under Section 2115 of the California Law ("Section 2115"), certain
corporations not organized under California law which have significant contacts
with California and which are not otherwise exempt from Section 2115 are subject
to a number of key provisions of the California Law. Because the Company had
significant contacts with California during the period specified in Section
2115, the Company believes that it is currently subject to Section 2115.
Accordingly, the Company is complying with certain provisions of the California
Law, including Section 301, regarding the election of directors. Section 301
does not permit the Company to have a classified Board. In connection with the
"Second Slate" each Stockholder will be voting to elect all three current
directors to hold office until the next annual meeting of Stockholders. Each
director to be elected will hold office until the next annual meeting of
Stockholders and until his successor is elected and has qualified, or until such
director's earlier death, resignation or removal. Each nominee is currently a
director of the Company, one director having been elected by the Stockholders,
and two directors, Michael J. Kucha and Timothy Saxe, having been elected by the
Board.
 
    Under Section 2115, Stockholders are permitted to exercise cumulative voting
rights. Under cumulative voting, each holder of Common Stock will be entitled to
three votes for each share held. Each Stockholder may give one candidate, who
has been nominated prior to voting, all the votes such Stockholder is entitled
to cast or may distribute such votes among as many such candidates as such
Stockholder chooses. (However, no Stockholder will be entitled to cumulate votes
unless the candidate's name has been placed in nomination prior to the voting
and at least one Stockholder has given notice at the meeting, prior to the
voting, of his or her intention to cumulate votes). Unless the proxyholders are
otherwise instructed, Stockholders, by means of the accompanying proxy, will
grant the proxyholders discretionary authority to cumulate votes.
 
    Shares represented by executed proxies will be voted, if authority to do so
is not withheld, for the election of the three nominees enumerated above. 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.
 
    Pursuant to the Second Slate, the three candidates receiving the highest
number of affirmative votes cast at the meeting will be elected directors of the
Company.
 
       THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF EACH NOMINEE

                                   PROPOSAL 2
                       APPROVAL OF 1999 STOCK OPTION PLAN
 
    In January 1999, the Board adopted the Company's 1999 Stock Option Plan (the
"Option Plan"), subject to stockholder approval. There are 3,000,000 shares of
Common Stock reserved for issuance under the Option Plan. If the Stockholders
approve the Reverse Stock Split set forth in Proposal 4, the 3,000,000 shares of
Common Stock reserved for issuance under the Option Plan would be
proportionately reduced in accordance with the provisions of the Option Plan.
 
    The Option Plan is intended to supplement the Company's currently existing
1996 Stock Option Plan (the "1996 Plan") and the Company's 1993 Stock Option
Plan (the "1993 Plan"). (Hereinafter, the 1996 Plan and the 1993 Plan will be
collectively referred to as the "Prior Plans.") The 1996 Plan authorizes the
issuance of 2,000,000 shares of the Company's Common Stock. The 1993 Plan
authorizes the issuance of 3,000,000 shares of the Company's Common Stock. Both
of the Prior Plans are administered by the Compensation Committee of the Board.
Both of the Prior Plans allow for the issuance of incentive stock options,
nonstatutory stock options and stock appreciation rights.
 
    As of December 31, 1998, awards (net of canceled or expired options)
covering an aggregate of 1,808,192 shares of the Company's Common Stock had been
granted under the 1996 Plan. Only 174,707 shares of Common Stock (plus any
shares that might in the future be returned to the 1996 Plan as a result of
cancellations or expiration of awards) remained available for future grant under
the 1996 Plan. As of December 31, 1998, awards (net of canceled or expired
options) covering an aggregate of 1,484,761 shares of the Company's Common Stock
had been granted under the 1993 Plan. Only 327,074 shares of Common Stock (plus
any shares that might in the future be returned to the 1993 Plan as a result of
cancellations or expiration of awards) remained available for future grant under
the 1993 Plan.
 
    The Board approved the Option Plan in order to ensure that the Company can
continue to grant options and stock appreciation rights at levels and in the
manner determined appropriate by the Board.
 
    Stockholders are requested in this Proposal 2 to approve the Option Plan.
The affirmative vote of the holders of shares representing a least a majority of
the votes represented by the holders of Common Stock and the holders of
Preferred Stock, voting together as a single class on an as-if converted basis,
present in person or represented by proxy and entitled to vote at the Annual
Meeting will be required to approve the Option Plan. Abstentions will be counted
toward 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
this matter has been approved.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 2.
 
    The essential features of the Option Plan are outlined below:
 
GENERAL
 
    The Option Plan provides for the grant of incentive stock options,
nonstatutory stock options and stock appreciation rights (collectively
"awards"). Incentive stock options granted under the Option 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 Option Plan are not intended to qualify as incentive
stock options under the Code. Stock appreciation rights granted under the Option
Plan may be tandem rights, concurrent rights or independent rights. See "Federal
Income Tax Information" for a discussion of the tax treatment of awards. To
date, the Company has granted no stock awards under the Option Plan.
 
                                       5
<PAGE>
PURPOSE
 
    The Board adopted the Option Plan to provide a means by which employees,
directors and consultants of the Company and its affiliates may be given an
opportunity to purchase stock in the Company, to assist in retaining the
services of such persons, to secure and retain the services of persons capable
of filling such positions and to provide incentives for such persons to exert
maximum efforts for the success of the Company and its affiliates. All of the
approximately 37 employees, directors and consultants of the Company and its
affiliates are eligible to participate in the Option Plan.
 
ADMINISTRATION
 
    The Board administers the Option Plan. Subject to the provisions of the
Option Plan, the Board has the power to construe and interpret the Option Plan
and to determine the persons to whom and the dates on which awards will be
granted, the number of shares of Common Stock to be subject to each award, the
time or times during the term of each award within which all or a portion of
such award may be exercised, the exercise price, the type of consideration and
other terms of the award.
 
    The Board has the power to delegate administration of the Option Plan to a
committee of the Board. In the discretion of the Board, a committee may consist
solely of two or more outside directors in accordance with Section 162(m) of the
Code or solely of two or more non-employee directors in accordance with Rule
16b-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act").
As used herein with respect to the Option Plan, the "Board" refers to any
committee the Board appoints as well as to the Board itself.
 
    The regulations under Section 162(m) of the Code require that the directors
who serve as members of the committee must be "outside directors." The Option
Plan provides that, in the Board's discretion, directors serving on the
committee may be "outside directors" within the meaning of Section 162(m). This
limitation would exclude from the committee directors who are (i) current
employees of the Company or an affiliate, (ii) former employees of the Company
or an affiliate receiving compensation for past services (other than benefits
under a tax-qualified pension Option Plan), (iii) current and former officers of
the Company or an affiliate, (iv) directors currently receiving direct or
indirect remuneration from the Company or an affiliate in any capacity (other
than as a director), and (v) any other person who is otherwise considered an
"outside director" for purposes of Section 162(m). The definition of an "outside
director" under Section 162(m) is generally NARROWER than the definition of a
"non-employee director" under Rule 16b-3 of the Exchange Act.
 
ELIGIBILITY
 
    Incentive stock options and stock appreciation rights appurtenant thereto
may be granted under the Option Plan only to employees (including officers) of
the Company and its affiliates. Employees (including officers), directors, and
consultants of both the Company and its affiliates are eligible to receive
nonstatutory stock options and other types of stock appreciation rights under
the Option Plan.
 
    No incentive stock option may be granted under the Option Plan to any person
who, at the time of the grant, owns (or is deemed to own) stock possessing more
than 10% of the total combined voting power of the Company or any affiliate of
the Company, unless the exercise price is at least 110% of the fair market value
of the stock subject to the option on the date of grant and the term of the
option does not exceed five years from the date of grant. In addition, the
aggregate fair market value, determined at the time of grant, of the shares of
Common Stock with respect to which incentive stock options are exercisable for
the first time by an optionholder during any calendar year (under the Option
Plan and all other such plans of the Company and its affiliates) may not exceed
$100,000.
 
    No employee may be granted awards under the Option Plan exercisable for more
than 1,000,000 shares of Common Stock during any calendar year ("Section 162(m)
Limitation").
 
                                       6
<PAGE>
STOCK SUBJECT TO THE OPTION PLAN
 
    Subject to this Proposal, an aggregate of 3,000,000 shares of Common Stock
is reserved for issuance under the Option Plan. If awards granted under the
Option Plan expire or otherwise terminate without being exercised, the shares of
Common Stock not acquired pursuant to such awards again becomes available for
issuance under the Option Plan. If the Company reacquires unvested stock issued
under the Option Plan, the reacquired stock will not again become available for
reissuance under the Option Plan.
 
TERMS OF OPTIONS
 
    The following is a description of the permissible terms of options under the
Option Plan. Individual option grants may be more restrictive as to any or all
of the permissible terms described below.
 
    EXERCISE PRICE; PAYMENT.  The exercise price of incentive stock options may
not be less than 100% of the fair market value of the stock subject to the
option on the date of the grant and, in some cases (see "Eligibility" above),
may not be less than 110% of such fair market value. The exercise price of
nonstatutory options may not be less than 85% of the fair market value of the
stock on the date of grant. If options were granted with exercise prices below
market value, deductions for compensation attributable to the exercise of such
options could be limited by Section 162(m) of the Code. See "Federal Income Tax
Information." As of December 31, 1998, the closing price of the Company's Common
Stock as reported on the Nasdaq Unaffiliated Over the Counter Bulletin Board
(the "OTCBB") was $0.72 per share.
 
    The exercise price of options granted under the Option Plan must be paid
either in cash at the time the option is exercised or at the discretion of the
Board, (i) by delivery of other Common Stock of the Company, (ii) pursuant to a
deferred payment arrangement or (iii) in any other form of legal consideration
acceptable to the Board.
 
    OPTION EXERCISE.  Options granted under the Option Plan may become
exercisable in cumulative increments ("vest") as determined by the Board. Shares
covered by options under the Option Plan typically will vest over the course of
four years during the optionholder's employment by, or service as a director or
consultant to, the Company or an affiliate (collectively, "service"). Shares
covered by options granted under the Option Plan may, however, be subject to
different vesting terms. The Board has the power to accelerate the time during
which an option may vest or be exercised. In addition, options granted under the
Option Plan may permit exercise prior to vesting, but in such event the
optionholder may be required to enter into an early exercise stock purchase
agreement that allows the Company to repurchase unvested shares, generally at
their exercise price, should the optionholder's service terminate before
vesting. To the extent provided by the terms of an option, an optionholder may
satisfy any federal, state or local tax withholding obligation relating to the
exercise of such option by a cash payment upon exercise, by authorizing the
Company to withhold a portion of the stock otherwise issuable to the
optionholder, by delivering already-owned Common Stock of the Company or by a
combination of these means.
 
    TERM.  The maximum term of options under the Option Plan is 10 years, except
that in certain cases (see "Eligibility") the maximum term is five years.
Options under the Option Plan generally terminate three months after termination
of the optionholder's service unless (i) such termination is due to the
optionholder's permanent and total disability (as defined in the Code), in which
case the option may, but need not, provide that it may be exercised (to the
extent the option was exercisable at the time of the termination of service) at
any time within 12 months of such termination (or such longer or shorter period
as the Board may determine on the date of grant); (ii) the optionholder dies
before the optionholder's service has terminated, or within three months after
termination of such service, in which case the option may, but need not, provide
that it may be exercised (to the extent the option was exercisable at the time
of the optionholder's death) within 18 months of the optionholder's death (or
such longer or shorter period as the Board may determine on the date of grant)
by the person or persons to whom the rights to such option pass by will or by
the laws of descent and distribution; or (iii) the option by its terms
specifically
 
                                       7
<PAGE>
provides otherwise. An optionholder may designate a beneficiary who may exercise
the option following the optionholder's death. Individual option grants by their
terms may provide for exercise within a longer period of time following
termination of service.
 
    An optionholder's option agreement may provide that if the exercise of the
option following the termination of the optionholder's service would be
prohibited because the issuance of stock would violate the registration
requirements under the Securities Act of 1933, as amended (the "Securities
Act"), then the option will terminate on the earlier of (i) the expiration of
the term of the option or (ii) three months after the termination of the
optionholder's service during which the exercise of the option would not be in
violation of such registration requirements.
 
STOCK APPRECIATION RIGHTS
 
    The Option Plan authorizes three types of stock appreciation rights.
 
    TANDEM STOCK APPRECIATION RIGHTS.  Tandem stock appreciation rights are tied
to an underlying option and require the participant to elect whether to exercise
the underlying option or to surrender the option for an appreciation
distribution equal to the market price of the vested shares purchasable under
the surrendered option less the aggregate exercise price payable for such
shares. Appreciation distributions payable upon exercise of tandem stock
appreciation rights must be made in cash.
 
    CONCURRENT STOCK APPRECIATION RIGHTS.  Concurrent stock appreciation rights
are tied to an underlying option and are exercised automatically at the same
time the underlying option is exercised. The participant receives an
appreciation distribution equal to the market price of the vested shares
purchased under the option less the aggregate exercise price payable for such
shares. Appreciation distributions payable upon exercise of concurrent stock
appreciation rights must be made in cash.
 
    INDEPENDENT STOCK APPRECIATION RIGHTS.  Independent stock appreciation
rights are granted independently of any option and entitle the participant to
receive upon exercise an appreciation distribution equal to the market price of
a number of shares equal to the number of share equivalents to which the
participant is vested under the independent stock appreciation right less than
fair market value of such number of shares of stock on the date of grant of the
independent stock appreciation rights. Appreciation distributions payable upon
exercise of independent stock appreciation rights may, at the Board's
discretion, be made in cash, in shares of stock or a combination thereof.
 
RESTRICTIONS ON TRANSFER
 
    The optionholder may not transfer an incentive stock option otherwise than
by will or by the laws of descent and distribution. During the lifetime of the
optionholder, only the optionholder may exercise an incentive stock option. The
Board may grant nonstatutory stock options that are transferable generally.
Shares subject to repurchase by the Company under an early exercise stock
purchase agreement may be subject to restrictions on transfer that the Board
deems appropriate.
 
ADJUSTMENT PROVISIONS
 
    Transactions not involving receipt of consideration by the Company, such as
a stock dividend or stock split, may change the class and number of shares of
Common Stock subject to the Option Plan and outstanding awards. In that event,
the Option Plan will be appropriately adjusted as to the class and the maximum
number of shares of Common Stock subject to the Option Plan and the Section
162(m) Limitation, and outstanding options will be adjusted as to the class,
number of shares and price per share of Common Stock subject to such awards.
 
                                       8
<PAGE>
EFFECT OF CERTAIN CORPORATE EVENTS
 
    The Option Plan provides that, in the event of a sale of substantially all
of the assets of the Company, specified types of merger, or other corporate
reorganization (a "change in control"), any surviving corporation may either
assume options outstanding under the Option Plan or substitute similar options
for those outstanding under the Option Plan. If any surviving corporation
declines to assume options outstanding under the Option Plan, or to substitute
similar options, then, the vesting and the time during which such options may be
exercised will be accelerated; an any such outstanding option will terminate if
the optionholder does not exercise it before a change in control. Additionally,
the standard form of Stock Option Agreement under the Option Plan provides that
any option which remains in effect after a change in control (or which is
assumed or substituted following a change in control) shall accelerate in
vesting and exercisability so that 50% of any unvested shares covered by such an
option will immediately vest and become exercisable upon the effective date of
the change in control; the remaining 50% of the unvested shares covered by such
an option will vest and become exercisable in accordance with the original
schedule for vesting and exercisability, but in no event will such remaining
period of vesting be longer than two years from the effective date of the change
in control. Moreover, if the continuous service of the optionholder with Company
or an affiliate is terminated without cause or due to a constructive termination
(that is, a voluntary termination with good reason) within one month prior to or
six months following the effective date of a change in control, then all
remaining shares covered by any outstanding option granted under the Option Plan
and held by such optionholder will vest and become exercisable as of the date of
such termination.
 
DURATION, AMENDMENT AND TERMINATION
 
    The Board may suspend or terminate the Option Plan without stockholder
approval or ratification at any time or from time to time. Unless sooner
terminated, the Option Plan will terminate on January 25, 2009.
 
    The Board may also amend the Option Plan at any time or from time to time.
However, no amendment will be effective unless approved by the stockholders of
the Company within 12 months before or after its adoption by the Board if the
amendment would (i) modify the requirements as to eligibility for participation
(to the extent such modification requires stockholder approval in order for the
Option Plan to satisfy Section 422 of the Code, if applicable, or Rule 16b-3 of
the Exchange Act); (ii) increase the number of shares reserved for issuance upon
exercise of awards; or (iii) change any other provision of the Option Plan in
any other way if such modification requires stockholder approval in order to
comply with Rule 16b-3 of the Exchange Act or satisfy the requirements of
Section 422 of the Code or any securities exchange listing requirements. The
Board may submit any other amendment to the Option Plan for stockholder
approval, including, but not limited to, amendments intended to satisfy the
requirements of Section 162(m) of the Code regarding the exclusion of
performance-based compensation from the limitation on the deductibility of
compensation paid to certain employees.
 
FEDERAL INCOME TAX INFORMATION
 
    Long-term capital gains currently are generally subject to lower tax rates
than ordinary income or short-term capital gains. The maximum long-term capital
gains rate for federal income tax purposes is currently 20% while the maximum
ordinary income rate and short-term capital gains rate are effectively 39.6%.
Slightly different rules may apply to optionholders who acquire stock subject to
certain repurchase options or who are subject to Section 16(b) of the Exchange
Act.
 
    INCENTIVE STOCK OPTIONS.  Incentive stock options under the Option Plan are
intended to be eligible for the favorable federal income tax treatment accorded
"incentive stock options" under the Code.
 
                                       9
<PAGE>
    There generally are no federal income tax consequences to the optionholder
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
optionholder's alternative minimum tax liability, if any.
 
    If an optionholder 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
optionholder upon exercise of the option, any gain or loss on a disposition of
such stock will be a long-term capital gain or loss if the optionholder held the
stock for more than one year.
 
    Generally, if the optionholder disposes of the stock before the expiration
of either of these holding periods (a "disqualifying disposition"), then at the
time of disposition the optionholder will realize taxable ordinary income equal
to the lesser of (i) the excess of the stock's fair market value on the date of
exercise over the exercise price, or (ii) the optionholder's actual gain, if
any, on the purchase and sale. The optionholder'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.
 
    To the extent the optionholder recognizes ordinary income by reason of a
disqualifying disposition, the Company will generally be entitled (subject to
the requirement of reasonableness, the provisions of Section 162(m) of the Code
and the satisfaction of a tax reporting obligation) to a corresponding business
expense deduction in the tax year in which the disqualifying disposition occurs.
 
    NONSTATUTORY STOCK OPTIONS.  Nonstatutory stock options granted under the
Option Plan generally have the following federal income tax consequences:
 
    There are no tax consequences to the optionholder or the Company by reason
of the grant of a nonstatutory stock option. Upon exercise of a nonstatutory
stock option, the optionholder normally will recognize taxable ordinary income
equal to the excess, if any, of the stock's fair market value on the date of
exercise over the option exercise price. 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 participant 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. Subject to the requirement of
reasonableness, the provisions of Section 162(m) of the Code and the
satisfaction of a tax reporting obligation, the Company will generally be
entitled to a business expense deduction equal to the taxable ordinary income
realized by the optionholder.
 
    Upon disposition of the stock, the optionholder 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 (or vesting of the stock). Such gain or loss will be
long-term or short-term depending on whether the stock was held for more than
one year. Slightly different rules may apply to optionholders who acquire stock
subject to certain repurchase options or who are subject to Section 16(b) of the
Exchange Act.
 
    STOCK APPRECIATION RIGHTS.  No taxable income is realized upon the receipt
of a stock appreciation right, but upon exercise of the stock appreciation right
the fair market value of the shares (or cash in lieu of shares) received must be
treated as compensation taxable as ordinary income to the participant in the
year of such exercise. Generally, with respect to employees, the Company is
required to withhold from the payment made on exercise of the stock appreciation
right or from regular wages or supplemental wage payments an amount based on the
ordinary income recognized. Subject to the requirement of reasonableness,
Section 162(m) of the Code and the satisfaction of a reporting obligation, the
Company will be entitled to a business expense deduction equal to the taxable
ordinary income recognized by the participant.
 
    POTENTIAL LIMITATION ON COMPANY DEDUCTIONS.  Section 162(m) of the Code
denies a deduction to any publicly held corporation for compensation paid to
certain "covered employees" in a taxable year to the
 
                                       10
<PAGE>
extent that compensation to such covered employee exceeds $1 million. It is
possible that compensation attributable to stock options, 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 and stock appreciation rights will qualify as
performance-based compensation if the award is granted by a compensation
committee comprised solely of "outside directors" and either (i) the plan
contains a per-employee limitation on the number of shares for which such awards
may be granted during a specified period, the per-employee limitation is
approved by the stockholders, and the exercise price of the award is no less
than the fair market value of the stock on the date of grant, or (ii) the award
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 award is approved by stockholders.

                                   PROPOSAL 3
 
                 APPROVAL OF 1999 EMPLOYEE STOCK PURCHASE PLAN
 
    In January 1999, the Board adopted the Company's 1999 Employee Stock
Purchase Plan (the "Purchase Plan"), subject to Stockholder approval. There are
1,000,000 shares of Common Stock reserved for issuance under the Purchase Plan.
If the Stockholders approve the Reverse Stock Split set forth in Proposal 4, the
1,000,000 shares of Common Stock reserved for issuance under the Purchase Plan
would be proportionately reduced in accordance with the provisions of the
Purchase Plan.
 
    The Purchase Plan is intended to supplement and replace the Company's
currently existing Employees' Stock Purchase Plan (the "Old Plan"). The Old Plan
qualifies as an "employee stock purchase plan" under Section 423 of the Code.
The Old Plan authorizes the issuance of 700,000 shares of Common Stock. The Old
Plan allows for the grant of rights to eligible employees to purchase Common
Stock at a price which is the lesser of the fair market value of the shares on
the date on which such rights are granted, which day shall be the first day of
the purchase period, or the fair market value of the shares on the date such
shares are purchased. Under the Old Plan, rights are granted for purchase
periods, which are three months in length. Purchase periods begin on January 1,
April 1, July 1, and October 1. Currently, generally all employees are eligible
to participate in the Old Plan except employees customarily employed less than
20 hours per week or who have not been employed for at least 30 days prior to
the beginning of a purchase period or who, after the granting of purchase
rights, would own more than 5% of the outstanding shares of the Company.
 
    During the last fiscal year, shares of Common Stock were purchased in the
amounts and at the weighted average prices per share under the Old Plan as
follows: James R. Fiebiger, 1,722 shares ($1.31 per share), Charles Parr, 802
shares ($1.31 per share), Charles Parr, 2,502 shares ($0.30 per share), Charles
Parr, 1,238 shares ($1.06 per share), all current executive officers as a group
6,264 shares ($0.75 per share), and all employees (excluding executive officers)
as a group 194,198 shares ($0.75 per share).
 
    As of December 31, 1998 purchase rights (net of canceled or expired purchase
rights) covering an aggregate of 619,818 shares of the Company's Common Stock
had been granted under the Old Plan. Only 80,182 shares of Common Stock (plus
any shares that might in the future be returned to the Old Plan as a result of
cancellations or expiration of purchase rights) remained available for future
grant under the Old Plan.
 
    Pending stockholder approval of the new Purchase Plan, the Company will
terminate the Old Plan effective on or about June 30, 1999. The Board approved
the new Purchase Plan in order to ensure the Company can continue to grant
purchase rights at levels and in the manner determined appropriate by the Board.
 
    Stockholders are requested in this Proposal 3 to approve the Purchase Plan.
The affirmative vote of the holders of shares representing at least a majority
of votes represented by the holders of Common Stock and the holders of Preferred
Stock, voting together as a single class on an as-if converted basis present in
person or represented by proxy and entitled to vote at the Annual Meeting will
be required to approve the Purchase Plan. Abstentions will be counted toward 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 this matter
has been approved.

                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 3.
 
    The essential features of the Purchase Plan, as amended, are outlined below:
 
PURPOSE
 
    The purpose of the Purchase Plan is to provide a means by which employees of
the Company (and any parent or subsidiary of the Company designated by the Board
to participate in the Purchase Plan) may be given an opportunity to purchase
Common Stock of the Company through payroll deductions, to assist the Company in
retaining the services of its employees, to secure and retain the services of
new employees, and to provide incentives for such persons to exert maximum
efforts for the success of the Company. All of the Company's approximately 37
employees are eligible to participate in the Purchase Plan.
 
    The rights to purchase Common Stock granted under the Purchase Plan are
intended to qualify as options issued under an "employee stock purchase plan" as
that term is defined in Section 423(b) of the Code.
 
ADMINISTRATION
 
    The Board administers the Purchase Plan and has the final power to construe
and interpret both the Purchase Plan and the rights granted under it. The Board
has the power, subject to the provisions of the Purchase Plan, to determine when
and how rights to purchase Common Stock of the Company will be granted, the
provisions of each offering of such rights (which need not be identical), and
whether employees of any parent or subsidiary of the Company will be eligible to
participate in the Purchase Plan.
 
    The Board has the power to delegate administration of the Purchase Plan to a
committee composed of not fewer than two members of the Board. As used herein
with respect to the Purchase Plan, the "Board" refers to any committee the Board
appoints as well as to the Board itself.
 
OFFERINGS
 
    The Purchase Plan is implemented by offerings of rights to all eligible
employees from time to time by the Board. The initial offering under the Plan
will begin on August 1, 1999 and will be 18 months long. This initial offering
will be divided into three shorter "purchase periods," each of which will be
approximately six months long. Thereafter, unless otherwise determined by the
Board, a new offering will begin on February 1 of each year, beginning with
February 1, 2001. Each such offering will be one year long and will be divided
into two shorter "purchase periods" approximately six months long. Purchase
dates under the Purchase Plan will generally be January 31 and July 31 of each
year.
 
ELIGIBILITY
 
    Any person who is customarily employed at least 20 hours per week and five
months per calendar year by the Company (or by any parent or subsidiary of the
Company designated by the Board) on the first day of an offering is eligible to
participate in that offering. Officers of the Company who are "highly
compensated" as defined in the Code are eligible to participate in the Purchase
Plan.
 
    However, no employee is eligible to participate in the Purchase Plan if,
immediately after the grant of purchase rights, the employee would own, directly
or indirectly, stock possessing 5% or more of the total combined voting power or
value of all classes of stock of the Company or of any parent or subsidiary of
the Company (including any stock which such employee may purchase under all
outstanding rights and options). In addition, no employee may purchase more than
$25,000 worth of Common Stock (determined at the fair market value of the shares
at the time such rights are granted) under all employee stock purchase plans of
the Company and its affiliates in any calendar year.
 
                                       13
<PAGE>
PARTICIPATION IN THE PLAN
 
    Eligible employees enroll in the Purchase Plan by delivering to the Company,
prior to the date selected by the Board as the offering date for the offering,
an agreement authorizing payroll deductions of up to 15% of such employees'
compensation during the offering.
 
PURCHASE PRICE
 
    The purchase price per share at which shares of Common Stock are sold in an
offering under the Purchase Plan is the lower of (i) 85% of the fair market
value of a share of Common Stock on first day of the offering or (ii) 85% of the
fair market value of a share of Common Stock on the last day of the purchase
period.
 
PAYMENT OF PURCHASE PRICE; PAYROLL DEDUCTIONS
 
    The purchase price of the shares is accumulated by payroll deductions over
the offering. At any time during the offering, a participant may reduce or
terminate his or her payroll deductions as the Board provides in the offering. A
participant may not increase or begin such payroll deductions after the
beginning of any purchase period, except, if the Board provides, in the case of
an employee who first becomes eligible to participate as of a date specified
during the purchase period. All payroll deductions made for a participant are
credited to his or her account under the Purchase Plan and deposited with the
general funds of the Company. A participant may not make additional payments
into such account, unless specifically provided in the offering and unless the
participant has not had the maximum amount withheld during the offering.
 
PURCHASE OF STOCK
 
    By executing an agreement to participate in the Purchase Plan, the employee
is entitled to purchase shares under the Purchase Plan. In connection with
offerings made under the Purchase Plan, the Board specifies a maximum number of
shares of Common Stock an employee may be granted the right to purchase and the
maximum aggregate number of shares of Common Stock that may be purchased
pursuant to such offering by all participants. For the initial offering (and for
subsequent offerings unless otherwise determined by the Board), the maximum
aggregate number of shares available to be purchased will be the number of
shares remaining available under the Purchase Plan on the offering date; the
maximum aggregate number of shares available to be purchased by all eligible
employees on a purchase date shall be 200,000 shares of Common Stock. If the
aggregate number of shares to be purchased upon exercise of rights granted in
the offering would exceed the maximum aggregate number of shares of Common Stock
available, the Board will make a pro rata allocation of available shares in a
uniform and equitable manner. Unless the employee's participation is
discontinued, his or her right to purchase shares is exercised automatically at
the end of the purchase period at the applicable price. See "Withdrawal" below.
 
WITHDRAWAL
 
    While each participant in the Purchase Plan is required to sign an agreement
authorizing payroll deductions, the participant may withdraw from a given
offering by terminating his or her payroll deductions and by delivering to the
Company a notice of withdrawal from the Purchase Plan. Such withdrawal may be
elected at any time prior to the end of the applicable purchase period, except
as provided by the Board. For the initial offering, the Board has provided that
such withdrawal may be elected up to 10 days prior to the end of the applicable
purchase period.
 
    Upon any withdrawal from an offering by the employee, the Company will
distribute to the employee his or her accumulated payroll deductions without
interest, less any accumulated deductions previously applied to the purchase of
shares of Common Stock on the employee's behalf during such offering, and
 
                                       14
<PAGE>
such employee's interest in the offering will be automatically terminated. The
employee is not entitled to again participate in that offering. However, an
employee's withdrawal from an offering will not have any effect upon such
employee's eligibility to participate in subsequent offerings under the Purchase
Plan.
 
TERMINATION OF EMPLOYMENT
 
    Rights granted pursuant to any offering under the Purchase Plan terminate
immediately upon cessation of an employee's employment for any reason, and the
Company will distribute to such employee all of his or her accumulated payroll
deductions, without interest.
 
RESTRICTIONS ON TRANSFER
 
    Rights granted under the Purchase Plan are not transferable and may be
exercised only by the person to whom such rights are granted.
 
DURATION, AMENDMENT AND TERMINATION
 
    The Board may suspend or terminate the Purchase Plan at any time.
 
    The Board may amend the Purchase Plan at any time. Any amendment of the
Purchase Plan must be approved by the stockholders within 12 months of its
adoption by the Board if the amendment would (i) increase the number of shares
of Common Stock reserved for issuance under the Purchase Plan, (ii) modify the
requirements relating to eligibility for participation in the Purchase Plan, or
(iii) modify any other provision of the Purchase Plan in a manner that would
materially increase the benefits accruing to participants under the Purchase
Plan, if such approval is required in order to comply with the requirements of
Rule 16b-3 under the Exchange Act.
 
    Rights granted before amendment or termination of the Purchase Plan will not
be altered or impaired by any amendment or termination of the Purchase Plan
without consent of the employee to whom such rights were granted.
 
EFFECT OF CERTAIN CORPORATE EVENTS
 
    In the event of a dissolution, liquidation or specified type of merger of
the Company, the surviving corporation either will assume the rights under the
Purchase Plan or substitute similar rights, or the exercise date of any ongoing
offering will be accelerated such that the outstanding rights may be exercised
immediately prior to, or concurrent with, any such event.
 
STOCK SUBJECT TO PURCHASE PLAN
 
    Subject to this proposal, an aggregate of 1,000,000 shares of Common Stock
is reserved for issuance under the Purchase Plan. If rights granted under the
Purchase Plan expire, lapse or otherwise terminate without being exercised, the
shares of Common Stock not purchased under such rights again becomes available
for issuance under the Purchase Plan.
 
FEDERAL INCOME TAX INFORMATION
 
    Rights granted under the Purchase Plan are intended to qualify for favorable
federal income tax treatment associated with rights granted under an employee
stock purchase plan which qualifies under provisions of Section 423 of the Code.
 
    A participant will be taxed on amounts withheld for the purchase of shares
of Common Stock as if such amounts were actually received. Other than this, no
income will be taxable to a participant until disposition of the acquired
shares, and the method of taxation will depend upon the holding period of the
acquired shares.
 
                                       15
<PAGE>
    If the stock is disposed of at least two years after the beginning of the
offering period and at least one year after the stock is transferred to the
participant, then the lesser of (i) the excess of the fair market value of the
stock at the time of such disposition over the exercise price or (ii) the excess
of the fair market value of the stock as of the beginning of the offering period
over the exercise price (determined as of the beginning of the offering period)
will be treated as ordinary income. Any further gain or any loss will be taxed
as a long-term capital gain or loss. Such capital gains currently are generally
subject to lower tax rates than ordinary income.
 
    If the stock is sold or disposed of before the expiration of either of the
holding periods described above, then the excess of the fair market value of the
stock on the exercise date over the exercise price will be treated as ordinary
income at the time of such disposition. The balance of any gain will be treated
as capital gain. Even if the stock is later disposed of for less than its fair
market value on the exercise date, the same amount of ordinary income is
attributed to the participant, and a capital loss is recognized equal to the
difference between the sales price and the fair market value of the stock on
such exercise date. Any capital gain or loss will be short-term or long-term,
depending on how long the stock has been held.
 
    There are no federal income tax consequences to the Company by reason of the
grant or exercise of rights under the Purchase Plan. The Company is entitled to
a deduction to the extent amounts are taxed as ordinary income to a participant
(subject to the requirement of reasonableness and the satisfaction of tax
reporting obligations).

                                   PROPOSAL 4
      APPROVAL OF AMENDMENT TO CERTIFICATE TO EFFECT A REVERSE STOCK SPLIT
 
    On March 29, 1999, the Board of Directors considered and unanimously
adopted, subject to Stockholder approval, resolutions approving an amendment to
the Certificate to effect, at any time prior to the Company's 2000 Annual
Meeting of Stockholders, a reverse stock split of the Company's Common Stock
whereby each outstanding 10 shares of Common Stock would be combined, converted
and changed into one share of Common Stock (the "Reverse Stock Split") with the
effectiveness or the abandonment of such amendment, to be determined by the
Board. The proposed Reverse Stock Split would not have any effect on the number
of authorized shares of Common Stock. Accordingly, because the number of issued
and outstanding shares of Common Stock would be reduced ten-fold while the
number of authorized shares of Common Stock would remain unchanged, the proposed
Reverse Stock Split would have the effect of significantly increasing the number
of authorized shares available for future issuance.
 
    REASONS FOR REVERSE STOCK SPLIT
 
    The Board believes that the Reverse Stock Split may be desirable for a
number of reasons. First, the Board believes that the Reverse Stock Split may
improve the marketability and liquidity of the Company's Common Stock. Second,
the Reverse Stock Split may improve the Company's ability to raise new capital.
Finally, the Board believes that the Reverse Stock Split will enhance the
Company's ability to relist its shares on either the Nasdaq National Market
("Nasdaq NMS") or the Nasdaq SmallCap Market ("Nasdaq SmallCap"), subject to the
Company's compliance with the other listing criteria.
 
    The Board believes the Reverse Stock Split may have the effect of raising
the trading price of the Company's Common Stock. However, because some investors
may view the Reverse Stock Split negatively in that it reduces the number of
shares available in the public market, there can be no assurance that an
adjustment to the market price of the Common Stock will reflect proportionately
the Reverse Stock Split, or that such price, if it does rise proportionally to
such levels, will continue to escalate or be sustained in the future. The Board
believes that the increased market price of its Common Stock expected as a
result of the Reverse Stock Split will improve the marketability and liquidity
of the Company's Common Stock by appealing to a broader market than that which
currently exists and will encourage interest and trading in the Common Stock.
Many brokerage houses and institutional investors have internal policies and
practices that either prohibit them from investing in low-priced stocks or tend
to discourage individual brokers from recommending low-priced stocks to their
customers. Some of those policies and practices may function to make the
processing of trades in low-priced stocks economically unattractive to brokers.
Additionally, because brokers' commissions on low-priced stocks generally
represent a higher percentage of the stock price than commissions on
higher-priced stocks, the current average price per share of the Company's
Common Stock can result in individual stockholders paying transaction costs
representing a higher percentage of their total share value than would be the
case if the share price were substantially higher. If the Reverse Stock Split is
implemented, however, holders of fewer than 100 shares of Common Stock
("odd-lots") after the Reverse Stock Split is effected may be charged brokerage
fees that are proportionately higher than holders of more than 100 shares of
Common Stock ("round-lots"). The Board is hopeful that the anticipated higher
market price will reduce, to some extent, the negative effects on the liquidity
and marketability of the Company's Common Stock inherent in some of the policies
and practices of institutional investors and brokerage houses.
 
    As of April 1, 1999, the Company had cash and cash equivalent balances of
approximately $1,298,089. The Company is currently generating losses, and
expects such losses to continue for at least the remainder of 1999.
Additionally, the Company had a working capital deficit of $3.5 million at
December 31, 1998. Therefore the Company needs additional capital to continue
funding its operations. Unless it obtains such funding, the Company will have
utilized all of its currently-available capital resources on or about April 30,
1999. Accordingly on January 26, 1999, the Board authorized management to pursue
efforts to sell Common Stock or Preferred Stock in order to raise additional
capital to finance the Company's operations as well as to seek other sources of
funds. The Board has authorized management to seek from $10 million
 
                                       17
<PAGE>
to $12.5 million in additional capital to fund operations. If, however, there is
a greater interest among potential investors on terms acceptable to the Company,
the Company may raise more capital. The Reverse Stock Split may improve the
Company's ability to raise new capital by allowing the Company the flexibility
to issue additional Common Stock or securities convertible into Common Stock in
accordance with the Certificate.
 
    The Company had contacted a number of potential providers of additional
capital, including investment banking firms, financial investors, customers,
potential customers, strategic partners and potential strategic partners. In
this regard, management has held discussions with Idanta Partners Ltd. and Actel
Corporation, each a significant stockholder of the Company (together with their
affiliates, the "Investor Stockholders"), in which the Investor Stockholders
have indicated their preliminary interest in providing additional financing (the
"Proposed Financing").
 
    Pursuant to the Proposed Financing, the Company has held discussions with
the Investor Stockholders in which the Investor Stockholders have indicated on a
preliminary basis their willingness to extend loans to the Company in the
aggregate principal amount of $8 million. The Company currently anticipates that
capital in the aggregate principal amount of $6 million to $12 million would
meet the Company's capital requirements through 1999. However, the Company's
capital requirements may be greater than anticipated. Therefore, there can be no
assurance that such amounts will be sufficient to meet the Company's capital
requirements through 1999. It is anticipated that all or some portion of such
loans from the Investor Stockholders would be convertible into shares of Common
Stock. It is anticipated that the Common Stock issuable upon conversion would be
at a discount to the prevailing market price to reflect the illiquidity of the
shares, the Company's financial condition and other factors.
 
    Although the Investor Stockholders have indicated their preliminary interest
in funding the Company, there can be no assurance that the Proposed Financing
will be consummated within a reasonable time frame on terms acceptable to the
Company or at all. The terms of such financings have not been determined and
will be subject to compliance with all applicable securities laws. The terms of
such financings will be approved by all members of the Company's Board of
Directors. If the Company is unable to obtain additional financing on a timely
basis, the Company will be required to terminate its operations. The issuance of
additional shares of Common Stock in the Proposed Financing is expected to be
dilutive to the current stockholders, particularly in view of the fact that such
securities will likely be issued at a discount to the prevailing market price of
the Company's Common Stock.
 
    In addition, the Company believes an increase in the per share price of the
Company's Common Stock, which the Company expects as a consequence of the
Reverse Stock Split, may make the Common Stock more acceptable to the financial
community and the investing public, thereby broadening the investor pool from
which the Company might be able to obtain additional financing. In theory, the
total number of shares outstanding should not, by itself, affect the
marketability of the Common Stock, the type of investor who acquires it or the
Company's reputation in the financial community. As a practical matter, however,
the opposite is in fact often the case. For example, because of the trading
volatility often associated with low-priced stocks, many institutional investors
are prohibited from purchasing such stocks as a matter of policy. For the same
reason, brokers often discourage their customers from purchasing such stocks.
The Reverse Stock Split and the resulting reduction in the number of outstanding
shares of Common Stock is anticipated initially to increase proportionally the
per share market price of the Common Stock. Accordingly, the Company believes,
such initial increase will have a positive impact on the Company's ability to
obtain capital from outside sources.
 
    The Board also believes the Reverse Stock Split will enhance the Company's
ability to relist its shares on either Nasdaq NMS or Nasdaq SmallCap. On July
15, 1998, the Company's stock was delisted from the Nasdaq NMS and began trading
on the Nasdaq SmallCap. On September 17, 1998, the Company's Stock was delisted
from Nasdaq SmallCap for failing to meet Nasdaq's ongoing minimum bid price
requirement. At that date, the Company's stock began trading on the NASD
Electronic Bulletin Board (the "OTCBB"). The Board believes that the Reverse
Stock Split may have the effect of enabling the Company to meet certain criteria
set forth by the Nasdaq NMS, thereby enabling the Company to relist its stock.
In order to
 
                                       18
<PAGE>
become relisted on the Nasdaq NMS, the Company must meet certain criteria. The
rules of the Nasdaq NMS require that as a condition of listing of a Company's
securities on the Nasdaq NMS, the Company satisfy at least one of several
alternative maintenance requirements, which generally require that a company
meet certain minimum criteria relating to its financial condition, results of
operations and trading market for its listed securities. The maintenance
criteria most applicable to the Company consist of maintaining (i) a public
float of at least 1.1 million shares, (ii) a market value of the public float of
at least $8 million, (iii) a minimum bid price equal to or greater than $5.00
per share, (iv) at least 400 stockholders (round-lot holders), (v) net tangible
assets of at least $6 million, (vi) at least three registered market makers and
(vii) compliance with certain corporate governance requirements. Although the
Company currently does not satisfy criteria (iii) and (v) the Company believes
that effecting a Reverse Stock Split will help its Common Stock meet the minimum
bid price requirement. There can be no assurances, however, that the Company
will be successful in meeting these criteria or that, even if these maintenance
criteria are met, Nasdaq will list the Company's Common Stock on the Nasdaq NMS.
 
    If the Company is not successful in meeting the Nasdaq NMS criteria, a
Reverse Stock Split may, in the alternative, enable the Company to relist its
shares on Nasdaq SmallCap. The rules of Nasdaq SmallCap require that as a
condition of listing of a Company's securities on the Nasdaq SmallCap, the
Company must meet certain minimum criteria relating to its financial condition
results of operations and trading market for its listed securities. The
maintenance criteria consist of maintaining: (i) a public float of at least 1.0
million shares; (ii) a market value of the public float of at least $5 million;
(iii) a minimum bid price equal to or greater than $4.00 per share; (iv) at
least 300 stockholders (round-lot holders); (v) net tangible assets of at least
$4 million or market capitalization of $50 million or net income in the latest
fiscal year or two of the last three fiscal years of $750,000; (vi) at least
three registered market makers; (vii) an operating history of at least one year;
and (viii) compliance with certain corporate governance requirements. Although
the Company currently does not satisfy criteria (iii) and (v), the Company
believes that effecting a Reverse Stock Split will help its Common Stock meet
the minimum bid price requirement. There can be no assurances, however, that the
Company will be successful in meeting these criteria or that, even if these
maintenance criteria are met, Nasdaq will list the Company's Common Stock on the
Nasdaq SmallCap.
 
    Stockholders should note that the effect of the Reverse Stock Split upon the
market prices for the Company's Common Stock cannot be accurately predicted. In
particular, there is no assurance that prices for shares of the Common Stock
after the Reverse Stock Split will be 10 times the prices for shares of the
Common Stock immediately prior to the Reverse Stock Split. In fact, oftentimes,
other companies who have effected reverse stock splits have experienced declines
in the price of their common stock.. Furthermore, there can be no assurance that
a Reverse Stock Split will achieve the desired results which have been outlined
above, nor can there be any assurance that a Reverse Stock Split will not
adversely impact the market price of the Common Stock, or, alternatively, that
any increased price per share of the Common Stock immediately after a Reverse
Stock Split will be sustained for any prolonged period of time.
 
    EFFECTS OF THE REVERSE STOCK SPLIT ON REGISTRATION AND VOTING RIGHTS
 
    The Company's Common Stock is currently registered under Section 12(g) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Company is subject to the periodic reporting and other requirements of the
Exchange Act. The Reverse Stock Split will not affect the registration of the
Company's Common Stock under the Exchange Act and the Company will continue to
be subject to the listing and reporting requirements set forth therein. After
the Reverse Stock Split, the Company's Common Stock will continue to be reported
on the "pink sheets" maintained by the National Quotation Bureau, Inc. or OTCBB
under the symbol "GATE". The Company has no current plans to go private, and the
proposed Reverse Stock Split is not the first step in such a transaction or
series of transactions.
 
    Proportionate voting rights and other rights of the holders of Common Stock
will not be affected by the Reverse Stock Split (other than as a result of the
payment of cash in lieu of fractional shares as described below). For example, a
holder of 2% of the voting power of the outstanding shares of Common
 
                                       19
<PAGE>
Stock immediately prior to the effective time of the Reverse Stock Split will
continue to hold 2% of the voting power of the outstanding shares of Common
Stock after the Reverse Stock Split. Although the Reverse Stock Split will not
affect the rights of stockholders or any stockholder's proportionate equity
interest in the Company (subject to the treatment of fractional shares), the
number of authorized shares of Common Stock will not be reduced and will
increase significantly the ability of the Board to issue such authorized and
unissued shares without further Stockholder action. The number of Stockholders
of record will be reduced as a result of the Reverse Stock Split. Based on the
1,226 Stockholders of record at April 8, 1999, a one-for-ten reverse stock split
would have the effect of reducing the number of Stockholders of record by
approximately 284, to a total of approximately 942 Stockholders of record.
 
    EFFECTS OF THE REVERSE STOCK SPLIT ON STOCK OPTIONS, RIGHTS UNDER THE
    EMPLOYEES' STOCK PURCHASE PLAN AND PAR VALUE
 
    The Reverse Stock Split will effect a reduction in the number of shares of
Common Stock available for issuance under the Company's 1993 Stock Option Plan,
1996 Stock Option Plan and 1995 Stock Option Directors' Plan for Non-Employee
Directors and the number of shares issuable upon the exercise of rights
purchased under the Employees' Stock Purchase Plan (collectively, the "Plans")
in proportion to the exchange ratio of the Reverse Stock Split. The aggregate
number of shares of Common Stock currently authorized for issuance under the
Plans is 5,900,000 (prior to giving effect to the Reverse Stock Split). The par
value of the Company's Common Stock will remain at $0.10 per share following the
effective time of the Reverse Stock Split, while the number of shares of Common
Stock issued and outstanding will be reduced. Consequently, the aggregate par
value of the issued and outstanding Common Stock also will be reduced. In
addition, the number of authorized but unissued shares of Common Stock
effectively will be increased significantly by the Reverse Stock Split. For
instance, based on the 41,545,531 shares of Common Stock outstanding on April 8,
1999, and given the 65,000,000 shares of Common Stock currently authorized under
the Certificate, there are 23,454,469 authorized but unissued shares of Common
Stock available for future issuance prior to giving effect to the Reverse Stock
Split. A one-for-ten reverse stock split would have the effect of increasing the
number of authorized but unissued shares of Common Stock. Upon effectiveness of
the Reverse Stock Split, the 41,545,531 shares of Common Stock outstanding would
be reduced to 4,154,553 shares (without giving effect to the treatment of
fractional shares). The number of authorized shares, however, would remain
unchanged. Accordingly, rather than the 23,454,469 authorized but unissued
shares that were available for issuance prior to the effectiveness of the
Reverse Stock Split, there would be approximately 60,845,447 authorized but
unissued shares available for issuance after the effectiveness of the Reverse
Stock Split. The issuance of such additional authorized shares, if such shares
were issued, may have the effect of diluting the earnings per share and book
value per share, as well as the stock ownership and voting rights, of
outstanding Common Stock.
 
    The Company also has outstanding certain stock options to purchase shares of
the Company's Common Stock. Under the terms of the outstanding stock options,
the Reverse Stock Split will effect a reduction in the number of shares of
Company Common Stock issuable upon exercise of such stock options in proportion
to the exchange ratio of the Reverse Stock Split and will effect a proportionate
increase in the exercise price of such outstanding stock options. In connection
with the Reverse Stock Split, the number of shares of Common Stock issuable upon
exercise of outstanding stock options will be rounded to the nearest whole
share, and no cash payment will be made in respect of such rounding.
 
    CERTAIN ANTI-TAKEOVER EFFECTS
 
    The increase in the number of authorized but unissued shares of Common Stock
resulting from the Reverse Stock Split may be construed as having an
anti-takeover effect because the additional shares could be used by the Company
to oppose a hostile takeover attempt, delay or prevent changes in control or
management of the Company or delay or prevent any efforts to amend or repeal
certain provisions of the Company's Certificate or By-Laws. For example, without
further stockholder approval, the Board could strategically sell shares of
Common Stock in a private transaction to purchasers who would oppose a takeover
or favor the current Board. Although the Reverse Stock Split has been prompted
by business and
 
                                       20
<PAGE>
financial considerations and not by the threat of any hostile takeover attempt
(nor is the Board currently aware of any such attempts directed at the Company),
nevertheless, Stockholders should be aware that approval of the Reverse Stock
Split could facilitate future efforts by the Company to deter or prevent changes
in control of the Company, including transactions in which the Stockholders
might otherwise receive a premium for their shares over then current market
prices, even if such transactions were favored by a majority of the
disinterested Stockholders.
 
    In addition, the Company's current Certificate and By-Laws already contain
certain provisions which may delay, defer or make more difficult a takeover
attempt of the Company. For example, the Company's Certificate provides that the
Board will have the authority to issue up to 2,000,000 shares of Preferred Stock
and to determine the rights, preferences and privileges of those shares without
any further vote or action by the Stockholders. Preferred Stock could thus be
issued quickly, with terms calculated to delay or prevent a change of control of
the Company or make removal of management more difficult. The Company's
Certificate and By-Laws also provide, among other things, for a classified board
(the "Classified Board Provision"). The Classified Board Provision provides that
the Board shall be 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. The Classified Board Provision significantly extends
the time required to effect a change in control of the Board because only a
minority of directors are elected at each annual meeting of stockholders. As a
result, the Classified Board Provision tends to perpetuate present management
and may discourage hostile takeover bids for the Company, including some tender
offers that the Stockholders would feel were in their best interests. The
Classified Board Provision may be amended or repealed only by the affirmative
vote of the holders of at least 75% of the outstanding shares of voting stock of
the Company. Although, the Company does not currently contemplate implementing
additional anti-takeover measures, the Company may do so in the future if the
Board determines that such measures would be in the best interests of the
Company and its Stockholders.
 
    EFFECTS OF THE REVERSE STOCK SPLIT ON PREFERRED STOCK
 
    The Company has outstanding 18,003 shares of Series B Stock, currently
convertible into 82,498 shares of Common Stock, and 300,000 shares of Series C
Stock, currently convertible into 2,000,000 shares of Common Stock. Under the
Certificate, the Reverse Stock Split will effect a reduction in the number of
shares of Common Stock issuable upon conversion of such shares of Series B Stock
and Series C Stock in proportion to the exchange ratio of the Reverse Stock
Split. In connection with the Reverse Stock Split, the number of shares of
Common Stock issuable upon conversion of the Series B Stock and Series C Stock
will be rounded to the nearest whole share, and no cash payment will be made in
respect of such rounding.
 
    EFFECTIVE DATE
 
    The Reverse Stock Split would become effective as of the close of business
on the date of filing (the "Effective Date") of a Certificate of Amendment to
the Certificate with the office of the Secretary of State of the State of
Delaware. Except as explained below with respect to fractional shares, on the
Effective Date, shares of Common Stock issued and outstanding immediately prior
thereto (the "Old Common Stock"), will be, automatically and without any action
on the part of the Stockholders, converted into new shares of Common Stock in
accordance with the 1:10 Reverse Stock Split ratio.
 
    PAYMENT FOR FRACTIONAL SHARES
 
    No fractional shares of New Common Stock will be issued as a result of any
of the Reverse Stock Split. In lieu of any such fractional share interest, each
holder of Old Common Stock who as a result of the Reverse Stock Split would
otherwise receive a fractional share of New Common Stock will be entitled to
receive cash in an amount equal to the product obtained by multiplying (i) the
closing sales price of the Company's Common Stock on the Effective Date as
reported on the OTCBB by (ii) the number of shares of Old Common Stock held by
such holder that would otherwise have been exchanged for such fractional share
interest. Such amount will be issued to such holder in the form of a check in
accordance with the exchange procedures outlined under "Exchange of Stock
Certificates," below.
 
                                       21
<PAGE>
    EXCHANGE OF STOCK CERTIFICATES
 
    Shortly after the Effective Date, each holder of an outstanding certificate
theretofore representing shares of Old Common Stock will receive from EquiServe,
as the Company's exchange agent (the "Exchange Agent") for the Reverse Stock
Split, instructions for the surrender of such certificate to the Exchange Agent.
Such instructions will include a form of Transmittal Letter to be completed and
returned to the Exchange Agent. As soon as practicable after the surrender to
the Exchange Agent of any certificate which prior to the Reverse Stock Split
represented shares of Old Common Stock, together with a duly executed
Transmittal Letter and any other documents the Exchange Agent may specify, the
Exchange Agent shall deliver to the person in whose name such certificate had
been issued certificates registered in the name of such person representing the
number of full shares of New Common Stock into which the shares of Old Common
Stock previously represented by the surrendered certificate shall have been
reclassified and a check for any amounts to be paid in cash in lieu of any
fractional share interest. Each certificate representing shares of New Common
Stock issued in connection with the Reverse Stock Split will continue to bear
any legends restricting the transfer of such shares that were borne by the
surrendered certificates representing the shares of Old Common Stock. Until
surrendered as contemplated herein, each certificate which immediately prior to
the Reverse Stock Split represented any shares of Old Common Stock shall be
deemed at and after the Reverse Stock Split to represent the number of full
shares of New Common Stock contemplated by the preceding sentence.
 
    No service charges, brokerage commissions or transfer taxes shall be payable
by any holder of any certificate which prior to approval of the Reverse Stock
Split represented any shares of Old Common Stock, except that if any
certificates of New Common Stock are to be issued in a name other than that in
which the certificates for shares of Old Common Stock surrendered are
registered, it shall be a condition of such issuance that (i) the person
requesting such issuance shall pay to the Company any transfer taxes payable by
reason thereof (or prior to transfer of such certificate, if any) or establish

    NO APPRAISAL RIGHTS
 
    Under Delaware law, Stockholders of the Company are not entitled to
appraisal rights with respect to the proposed Reverse Stock Split.
 
    MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT
 
    A summary of the federal income tax consequences of the proposed Reverse
Stock Split to the Company and to individual Stockholders is set forth below.
The following discussion is based upon present federal income tax law. The
discussion is not intended to be, nor should it be relied on as, a comprehensive
analysis of the tax issues arising from or relating to the proposed Reverse
Stock Split. In addition, the Company has not sought and will not seek an
opinion of counsel or a ruling from the Internal Revenue Service regarding the
federal income tax consequences of the proposed Reverse Stock Split.
ACCORDINGLY, STOCKHOLDERS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS FOR MORE
DETAILED INFORMATION REGARDING THE EFFECTS OF THE PROPOSED REVERSE STOCK SPLIT
ON THEM UNDER APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN INCOME TAX LAWS.
 
    It is intended that the Reverse Stock Split will constitute a reorganization
(a "Reorganization") within the meaning of Section 368(a)(1)(E) of the Internal
Revenue Code of 1986, as amended. Assuming that the Reverse Stock Split
qualifies as a Reorganization, the following federal income tax consequences
should result:
 
    1.  A Stockholder will not recognize any gain or loss as a result of the
       Reverse Stock Split except to the extent a Stockholder receives cash in
       lieu of a fractional share. To the extent a Stockholder receives cash in
       lieu of a fractional share, for tax purposes the Stockholder will be
       deemed to
 
                                       22
<PAGE>
       have sold the fractional share to the Company. Although it is impossible
       to predict with certainty the tax consequences to any individual
       Stockholder, such Stockholder will likely recognize a gain or loss as a
       result of the repurchase of a fractional share equal to the difference
       between (i) the Stockholder's proportionate adjusted basis in such
       fractional share, and (ii) the cash amount received for such fractional
       share. Any gain will be treated as short-term capital gain taxable at a
       maximum federal income tax rate of 39.6% to a non-corporate Stockholder
       if the Stockholder has held his shares for one year or less prior to the
       Effective Date or long-term capital gain taxable at a maximum federal
       income tax rate of 20% to a non-corporate Stockholder if the Stockholder
       has held his shares for more than one year prior to the Effective Date.
 
    2.  The aggregate tax basis of the shares of New Common Stock received by
       the Stockholder pursuant to the Reverse Stock Split will equal the
       aggregate tax basis of the shares of Old Common Stock held by the
       Stockholder immediately prior to the Effective Date of the Reverse Stock
       Split reduced by any basis allocated to a fractional share for which the
       Stockholder receives cash. The Stockholder will be able to "tack" the
       holding period of the Old Common Stock prior to the Reverse Stock Split
       to the holding period of the New Common Stock received by the Stockholder
       as a result of the Reverse Stock Split, provided that the shares of Old
       Common Stock were capital assets in the hands of the Stockholder.
 
    3.  The Company will not recognize gain or loss as a result of the Reverse
       Stock Split.
 
    REQUIRED VOTE
 
    The affirmative vote of (i) the holders of shares representing at least a
majority of the votes represented by the holders of Common Stock, voting as a
separate class, (ii) the holders of shares representing at least a majority of
the votes represented by the holders of Preferred Stock, voting as a separate
class on an as-converted basis, and (iii) the holders of shares representing at
least a majority of the votes represented by the holders of Common Stock and
Preferred Stock, voting together as a single class on an as-converted basis is
necessary to approve the Reverse Stock Split and the amendment to the
Certificate to effect the Reverse Stock Split. Abstentions and broker non-votes
will have the same effect as negative votes.
 
            THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 4.
 
                                       23
<PAGE>
                                   PROPOSAL 5
 
  APPROVAL OF AMENDMENT TO CERTIFICATE TO EFFECT AN INCREASE IN THE NUMBER OF
                                   AUTHORIZED
                  SHARES OF COMMON STOCK AND PREFERRED STOCK.
 
    On January 26, 1999, the Board of Directors considered and unanimously
adopted, subject to Stockholder approval, an amendment to the Company's
Certificate to increase the Company's authorized number of shares of Common
Stock from 65,000,000 shares to 120,000,000 shares and the authorized number of
shares of Preferred Stock from 2,000,000 to 10,000,000 shares (the "Authorized
Share Increase"). The Board of Directors has reserved the discretion to abandon
the amendment set forth in this Proposal 5, as permitted under Section 242(c) of
the Delaware General Corporation Law in the event that the Reverse Stock Split
set forth in Proposal 4 is approved by the Stockholders.
 
    The additional Common Stock to be authorized by adoption of the amendment
would have rights identical to the currently outstanding Common Stock of the
Company. The additional Preferred Stock to be authorized would have such rights
as shall be designated from time to time by the Board of Directors and, if
required, as approved by the Stockholders. Adoption of the proposed amendment
and issuance of the Common Stock would not affect the rights of the holders of
currently outstanding Common Stock, Series B Stock or Series C Stock of the
Company, except for effects incidental to increasing the number of shares of the
Company's Common Stock outstanding, such as dilution of the earnings per share
and voting rights of current holders of Common Stock. If the amendment is
adopted, it will become effective upon filing of a Certificate of Amendment of
the Company's Restated Certificate of Incorporation ("Certificate of Amendment")
with the Secretary of State of the State of Delaware.
 
    The Certificate of Amendment would amend paragraph A of Article IV of the
Certificate to read in its entirety as follows:
 
    "A. The Corporation is authorized to issue a total of 130,000,000 shares of
all classes of stock, of which 120,000,000 shall be shares of Common Stock with
a par value of $.10 per share and 10,000,000 shall be shares of Series Preferred
Stock with a par value of $.10 per share."
 
    In addition to the 41,425,738 shares of Common Stock outstanding at December
31, 1998, the Board has reserved 82,498 shares of Common Stock for conversion of
the 18,003 shares of Series B Preferred Stock outstanding and 2,000,000 shares
of Common Stock for conversion of the 300,000 shares of Series C Preferred Stock
outstanding. The Board has also reserved a total of 5,900,000 shares of Common
Stock for issuance upon options and rights granted under the Company's stock
option plans, 3,523,782 shares of Common Stock which may be issued upon exercise
of a warrant held by Siemens Aktiengesellschaft ("Siemens") and approximately
302,474 shares of Common Stock which may be issued upon exercise of warrants
currently held by James R. Fiebiger, Halifax Fund, Capital Ventures
International, and Benjamin Huberman. Also, Siemens has the right to acquire
500,000 shares of Common Stock of the Company pursuant to the Siemens License
Agreement. See "Certain Transactions." This right expires in November 2000.
 
    REASON FOR AUTHORIZED SHARE INCREASE
 
    As discussed under Proposal 4, the Company is currently generating losses
and needs additional capital to continue funding operations. See "Proposal 4.
Reasons For Reverse Stock Split." The Authorized Share Increase will allow the
Company flexibility to issue additional Common Stock or securities convertible
into Common Stock in accordance with the Certificate.
 
    In addition to issuing additional shares of Common Stock or Preferred Stock
in connection with a Proposed Financing, Four Million (4,000,000) of the
additional shares of Common Stock that would become available for issuance if
the Authorized Share Increase were adopted by the Stockholders and if the Board
decided to effect the Authorized Share Increase would, pending Stockholder
approval of the 1999 Stock Option Plan pursuant to Proposal 2 and the 1999
Employee Stock Purchase Plan pursuant to
 
                                       23
<PAGE>
Proposal 3, be reserved for issuance pursuant to such option plans. See "Board
Discretion to Implement Authorized Share Increase."
 
    The additional shares of Common Stock and Preferred Stock that would become
available for issuance if the proposal were adopted could also be used by the
Company to oppose a hostile takeover attempt or delay or prevent changes in
control or management of the Company. For example, without further stockholder
approval, the Board could strategically sell shares of Common Stock or Preferred
Stock in a private transaction to purchasers who would oppose a takeover or
favor the current Board. Although this proposal to increase the authorized
Common Stock and Preferred Stock has been prompted by business and financial
considerations and not by the threat of any hostile takeover attempt (nor is the
Board currently aware of any such attempts directed at the Company),
nevertheless, stockholders should be aware that approval of this proposal could
facilitate future efforts by the Company to deter or prevent changes in control
of the Company, including transactions in which the stockholders might otherwise
receive a premium for their shares over then current market prices.
 
    BOARD DISCRETION TO IMPLEMENT AUTHORIZED SHARE INCREASE
 
    If the Authorized Share Increase is approved by the Stockholders, the
Authorized Share Increase will be effected, if at all, only if: (A) the
amendment regarding the Reverse Stock Split set forth in Proposal 4 is not
approved by the Stockholders; and (B) the Board determines that such Authorized
Share Increase is in the best interests of the Company and its Stockholders.
Therefore, notwithstanding approval of the Reverse Stock Split by the
Stockholders, the Board may, in its sole discretion, abandon the proposed
Authorized Share Increase and determine prior to effectiveness of any filing
with the Delaware Secretary of State not to effect the Authorized Share
Increase, as permitted under Section 242(c) of the Delaware General Corporation
Law. If the Board fails to implement the Authorized Share Increase prior to the
2000 Annual Meeting of Stockholders, Stockholder approval again would be
required prior to implementing any increase in the number of authorized shares
of Common Stock or Preferred Stock.
 
    NO APPRAISAL RIGHTS
 
    Under Delaware law, Stockholders of the Company are not entitled to
appraisal rights with respect to the proposed Authorized Share Increase.
 
    REQUIRED VOTE
 
    The affirmative vote of (i) the holders of shares representing at least a
majority of the votes represented by the holders of Common Stock, voting as a
separate class, (ii) the holders of shares representing at least a majority of
the votes represented by the holders of Preferred Stock, voting as a separate
class on an as-converted basis, and (iii) the holders of shares representing at
least a majority of the votes represented by the holders of Common Stock and
Preferred Stock, voting together as a single class on an as-converted basis, is
necessary to approve the Authorized Share Increase and the amendment to the
Company's Certificate to effect the Authorized Share Increase. Abstentions and
broker non-votes will have the same effect as negative votes.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 5.

                                   PROPOSAL 6
               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS
 
    The Board of Directors has selected Deloitte & Touche LLP as the Company's
independent auditors for the fiscal year ending December 31, 1999 and has
further directed that management submit the selection of independent auditors
for ratification by the stockholders at the Annual Meeting. Deloitte & Touche
LLP has audited the Company's financial statements since its inception in 1992.
Representatives of Deloitte & Touche 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 Deloitte & Touche LLP as the
Company's independent auditors is not required by the Company's By-laws or
otherwise. However, the Board is submitting the selection of Deloitte & Touche
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 different 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 Annual Meeting will
be required to ratify the selection of Deloitte & Touche LLP. Abstentions will
be counted toward 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 this matter has been approved.
 
                       THE BOARD OF DIRECTORS RECOMMENDS
                         A VOTE IN FAVOR OF PROPOSAL 6.

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 the fiscal year ended December 31, 1998, all

                             EXECUTIVE COMPENSATION
 
COMPENSATION OF DIRECTORS
 
    Each non-employee director of the Company receives a quarterly retainer of
$2,500 and a per meeting fee of $1,000 for each Board and committee meeting
attended. The members of the Board of Directors are also eligible for
reimbursement for their expenses incurred in connection with attendance at Board
meetings in accordance with Company policy. In the fiscal year ended December
31, 1998, the total compensation paid to non-employee directors was $57,758.
 
    Each non-employee director of the Company also receives stock option grants
under the 1995 Stock Option Directors' Plan for Non-Employee Directors (the
"Directors' Plan"). Only non-employee directors of the Company or an affiliate
of such directors (as defined in the Code) 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. Under the
Director's Plan, each non-employee director elected to the Board of Directors is
automatically granted, upon his or her initial election as a director, and
without further action by the Company, the Board or the stockholders of the
Company, an option to purchase 15,000 shares of Common Stock (an "Initial
Grant"). Each non-employee director is also granted an option to purchase 7,500
shares of Common Stock on the date of each Annual Meeting of Stockholders (an
"Annual Grant"). In no event shall any non-employee director receive an option
to purchase in the aggregate more than 100,000 shares pursuant to the Directors'
Plan. On May 13, 1998, the date of the 1997 Annual Meeting of Stockholders,
Messrs. Sandfort, Dunn and Huberman were each granted an option to purchase
7,500 shares of Common Stock at an exercise price of $1.50 per share, the fair
market value of the Common Stock on such date. On July 23, 1998, the date of his
appointment as a director by the Board, Mr. Kucha was granted an option to
purchase 15,000 shares of Common Stock at an exercise price of $0.83 per share,
the fair market value of the Common Stock on such date. All options granted
under the Director's Plan have or will have an exercise price equal to the fair
market value of the Common Stock on the date of grant and expire ten years from
the date of grant (subject to earlier termination in the event the optionee
ceases to serve as a director of the Company). Under the Directors' Plan,
options from an Initial Grant vest in full two years after the date of grant.
Options from an Annual Grant vest one year after the date of grant. The total
number of shares of Common Stock that may be issued under the Director's Plan is
200,000 shares. As of April 8, 1999, 75,000 shares had been granted under the
Directors' Plan. As of April 8, 1999, no options had been exercised under the
Directors' Plan.

(1) Options are non-qualified stock options. Options vest 25% on the first
    anniversary of the date of grant and thereafter at 1/48(th) per month. All
    options expire ten years from the date of grant. All options are subject to
    accelerated vesting upon the achievement of certain management business
    objectives. The options generally terminate three months following
    termination of the executive officer's employment with the Company or the
    expiration date, whichever occurs earlier. The exercise price of each is
    equal to the fair market value per share of the Common Stock on the date of
    grant. The Board of Directors may reprice options under the terms of the
    Company's option plans. In the event of a "change in control," 50% of any
    unvested portion of the option shall immediately vest upon the closing of
    such change in control transaction. The remaining 50% of any unvested
    portion of the Option shall vest per its original schedule but in no event
    shall such vesting period be longer than two years from the closing date of
    the change in control. If an employee is terminated for any reason other
    than for cause, within six months of a change in control event, then such
    option shall vest in its entirety upon such termination.
 
(2) The potential realizable value is based on the term of the option at its
    time of grant (10 years). It 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. These
    amounts represent certain assumed rates of appreciation only, in accordance
    with the rules of the SEC, and do not reflect the Company's estimate or
    projection of future stock price performance. Actual gains, if any, are
    dependent on the actual future performance of the Company's Common Stock and
    no gain to the optionee is possible unless the stock price increases over
    the option term, which will benefit all stockholders.

         REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
                          ON EXECUTIVE COMPENSATION(1)
 
    The Company's executive compensation program is administered by the
Compensation Committee of the Board of Directors (the "Committee"), which is
currently comprised of Messrs. Kucha and Sandfort, two of the Company's
non-employee directors. The Committee is responsible for determining the
salaries of, establishing bonus programs for, and granting stock options to, the
Company's executive officers, including the Chief Executive Officer (the "CEO").
In making decisions regarding executive compensation, other than for the CEO,
the Committee receives and considers input from the CEO. The CEO is not present
during the discussion of his compensation. In administering the executive
compensation program, including the salary to be paid to the CEO, the Committee
considers several elements designed to attract and retain key personnel, reward
outstanding performance, link executive pay to long-term Company performance and
to align executive interests with stockholder interests. These elements consist
of a base salary, annual bonuses, and long-term incentive stock awards.
 
    BASE SALARY
 
    The base salaries of the Company's executive officers are determined by the
Committee and, for executive officers other than the CEO, are based upon
recommendations from the CEO. In establishing base salaries for executive
officers, including the CEO, the Committee considers numerous factors such as:
salaries paid to executive officers in comparable positions at similar
companies, the executive's responsibilities, prior experience and breadth of
knowledge, the executive's importance to the Company, the executive's
performance in the prior year, historical salary levels of the executive and
relative salary levels

within the Company. Increases in base salary are generally based upon the
Committee's subjective review of enhanced individual performance and/or
increases in an executive's responsibilities.
 
    ANNUAL BONUS
 
    The Committee believes that it is important to tie a significant portion of
the compensation of executive officers to the attainment of corporate success,
thus aligning the objectives and rewards of Company executives with those of the
stockholders of the Company. The Committee awards executive bonuses based upon a
review of the bonuses given by comparable companies, and, for executive officers
other than the CEO, based upon recommendations from the CEO. Individual bonuses
are paid as a percentage of salary and are based upon the Company meeting
certain financial goals, in addition to the attainment of individual achievement
goals. The Company's financial goals are established by the Board of Directors
in the form of gross revenue and net income benchmarks. If the specified gross
revenue and net income benchmarks are achieved the Committee has discretion to
distribute bonuses to the Company's executives based upon their individual
contributions to the achievement of the Company's financial benchmarks.
Individual achievement goals are established for each executive, other than the
CEO, by the CEO. An executive's performance in meeting his or her specified
individual achievement goals, coupled with attainment of the Company's gross
revenue and net income goals, determines the total bonus for each executive in
any given year.
 
    LONG TERM INCENTIVE STOCK AWARDS
 
    The Company's Plans authorize the Committee to grant incentive or
non-qualified stock options to employees of the Company. The Committee
determines the prices and terms at which such options are granted. The Committee
uses stock options as a significant element of the compensation package of
executive officers, because it believes options provide an incentive to
executives to maximize stockholder value and because they compensate executives
only to the extent that the Company's stockholders receive a return on their
investment. Options vest 25% on the first anniversary of the date of grant and
thereafter at 2.08% per month. Moreover, options are subject to accelerated
vesting upon achievement of certain management business objectives and terminate
three months after the termination of the executive's employment with the
Company. Accordingly, such stock options serve as a means of retaining
executives. In determining the total number of shares of Common Stock to be
covered by option grants to executive officers in a given year, the Committee
takes into account the number of outstanding shares of Common Stock, the number
of shares reserved for issuance under the Company's Plans, recommendations of
management concerning option grants to employees below executive level, and the
Company's projected hiring needs for the coming year. In making individual stock
option grants to executives, the Committee considers the same factors considered
in the determination of base salary levels, as well as the stock and option
holdings of each executive and the remaining vesting schedule of such
executive's options.
 
    COMPENSATION OF CHIEF EXECUTIVE OFFICER
 
    The Committee uses the same procedures described above for the other
executive officers in setting the annual salary, bonus and stock option awards
for the CEO. In determining where the CEO's total compensation is set in light
of the considerations described above, the Committee subjectively evaluates such
factors as the CEO's performance and the achievement of the Company's financial
benchmarks. In determining the CEO's salary the Committee considers the salaries
paid to CEO's of similar companies. For fiscal 1998 the base salary of the CEO
was set at $180,000. In setting this amount, the Committee took into account Dr.
Fiebiger's experience and his value to the Company. In awarding stock options to
the CEO, the Committee considers, in addition to the factors enumerated above,
the CEO's stock and option holdings and the number of options still subject to
vesting. The CEO was not awarded any options in fiscal 1998 because the
Company's financial performance did not meet expectations. The CEO's annual
bonus is
 
                                       35
<PAGE>
dependent upon the criteria enumerated above for other executive officers. The
CEO did not earn a bonus in fiscal 1998 because the Company's financial
performance did not meet expectations.
 
    Section 162(m) of the Internal Revenue Code (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 statute containing this law
and the applicable proposed Treasury regulations offer a number of transitional
exceptions to this deduction limit for pre-existing compensation plans,
arrangements and binding contracts. As a result, the Compensation Committee
believes that at the present time it is quite unlikely that the compensation
paid to any Named Executive Officer in a taxable year which is subject to the
deduction limit will exceed $1 million. Therefore, the Compensation Committee
has not yet established a policy for determining which forms of incentive
compensation awarded to its Named Executive Officers shall be designed to
qualify as "performance-based compensation." The Compensation Committee intends
to continue to evaluate the effects of the statute and any final Treasury
regulations.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Prior to Mr. Jonathan S. Huberman's resignation from the Board, effective
March 9, 1999, the Company's compensation committee consisted of Jonathan S.
Huberman and Horst G. Sandfort, two of the Company's then, non-employee
directors. From September 1995 to June 1997, Mr. Sandfort was an employee and an
executive officer of the Company, serving as President of the Company's
GateField division. Mr. Huberman is a general partner of Idanta Partners, Ltd.
("Idanta"), a principal stockholder of the Company. Mr. Huberman was elected to
the Company's Board of Directors in 1997 in accordance with the terms of a Stock
Purchase Agreement (the "Idanta Agreement"), dated November 10, 1997, among the
Company, Idanta, the Dunn Family Trust and the Perscilla Family Trust (the
"Idanta Entities"). Pursuant to the Idanta Agreement, the Company agreed to
cause Messrs. Jonathan Huberman and David Dunn to be nominated for election to
the Board at the Company's 1997 Annual Meeting and for re-election to the
Company's Board on each proxy statement filed for each subsequent meeting of
stockholders as their respective terms expire, until the earlier of (i) the date
the Company first reports Annual Net Income (as defined in the Idanta Agreement)
of at least $15 million and (ii) the date that the Idanta Entities own less than
one half of the total number of shares of Preferred Stock and Common Stock
purchased pursuant to the Idanta Agreement. Messrs. Huberman and Dunn resigned
from the Board, effective March 9, 1999. Currently, the Compensation Committee
consists of Michael J. Kucha and Horst G. Sandfort. Mr. Kucha is an employee of
Idanta.
 
    On October 19, 1998, the Company was notified by the Idanta Entities of
their request that the Company redeem, in cash, an aggregate of 981,997 shares
of the Company's Series B Preferred Stock (the "Shares") at a redemption price
of equal to $4.5825 per share plus accrued dividends thereon. The Idanta
Entities became entitled, pursuant to the Idanta Agreement, to request
redemption of their shares upon the delisting of the Company's Common Stock from
the Nasdaq SmallCap Market. On December 16, 1998, the Company redeemed the
Shares for an aggregate price of $4,648,000. Eighteen Thousand and Three
(18,003) shares of Series B Preferred Stock remain outstanding.
 
    No executive officer of the Company serves as a member of the Board of
Directors or compensation committee of any entity which has one or more
executive officers serving as a member of the Company's Board of Directors or
Compensation Committee.

                              CERTAIN TRANSACTIONS
 
    On August 14, 1998, the Company and Actel Corporation ("Actel") entered into
a series of related transactions (collectively, the "Transaction"). As part of
the Transaction, the Company sold certain of the assets relating to its Design
Service Business unit, which is engaged in the business of providing prototyping
design services and verification services for electronic systems, integrated
circuits and other electronic components, located in Mt. Arlington, New Jersey
(the "Design Services Business") to Actel. The purchase price for such assets
was (i) $5.4 million plus (ii) contingent payments to be paid over a three-year
period on a quarterly basis based on the Design Services Business achieving
certain profitability levels which payments shall not exceed $1.0 million in the
aggregate. Also, as part of the Transaction, Actel purchased, and the Company
issued to Actel, 300,000 shares of the Company's Series C Preferred Stock for an
aggregate purchase price of $3,000,000 (the "Shares"). The Shares are initially
convertible into 2,000,000 shares of the Company's Common Stock and are entitled
to certain liquidation and redemption rights. Actel is entitled to certain
registration rights and shall have a right of first refusal to purchase its pro
rata share of certain new securities the company may issue. Also as part of the
Transaction, the Company and Actel entered into a Product Marketing Agreement
(the "Marketing Agreement"). Under the terms of the Marketing Agreement, Actel
received exclusive, worldwide distribution rights to the Company's standard
ProASIC FPGA products below .35 micron, including FPGA products that are
integrated with SRAM or Flash memory and all resulting next generation reduced
process geometry ProASIC FPGA products. For these rights, Actel agreed to pay
the Company an initial fee of $1.0 million and a $1.0 million fee upon
qualification of the initial .25 micron product. Finally, the Company and Actel
entered into a license agreement pursuant to which the Company granted to Actel
a fully paid, non-exclusive, non-transferable license to sell and upon certain
release events, make, have made, import and use the Company's standard ProASIC
FPGA products below .35 micron and all resulting next generation reduced process
geometry ProASIC FPGA products. Actel agreed to pay the Company a $1.0 million
fee for such license.
 
    On November 10, 1997, the Company, Idanta and the Idanta Entities entered
into a two phase private placement transaction, pursuant to the Idanta
Agreement. In phase one of the transaction, Idanta agreed to purchase 1,000,000
shares of the Company's Series B Preferred Stock for an aggregate purchase price
of $4,582,500. Each share of Series B Preferred Stock is convertible into 4.5825
shares of the Company's Common Stock. In addition, Idanta was required, under
the Idanta Agreement, to purchase 4,582,500 shares of the Company's Common Stock
for an aggregate purchase price of $4,582,500, pending Stockholder approval of
certain management proposals contained in the proxy statement filed in
connection with the Company's 1997 Annual Meeting. Upon the occurrence of
certain events, the Series B Preferred Stock was also subject to redemption at
the election of at least 51% of the then outstanding shares of Series B
Preferred Stock. On December 15, 1997, the Stockholders approved all the
management proposals. Accordingly, on January 14, 1998, in phase two of the
transaction, the Company sold, and the Idanta Entities purchased, an aggregate
of 4,582,500 shares of the Company's Common Stock for an aggregate purchase
price of $4,582,500. In addition, pursuant to the Idanta Agreement, the Company
agreed to cause Messrs. Jonathan Huberman and David Dunn to be nominated for
election to the Board at the 1997 Annual meeting and for re-election to the
Board on each proxy statement filed for each subsequent meeting of Stockholders
as their respective terms expire, until the earlier of (i) the date the Company
first reports Annual Net Income (as defined in the Idanta Agreement) of at least
$15 million and (ii) the date that the Idanta Entities (and their affiliates)
owns less than one-half of the total number of shares of preferred stock and
common stock purchased pursuant to the Idanta Agreement. On October 19, 1998,
the Company was notified by the Idanta Entities of their request that the
Company redeem, in cash, an aggregate of 981,997 shares of the Company's Series
B Preferred Stock (the "Shares") at a redemption price of equal to $4.5825 per
share plus accrued dividends thereon. The Idanta Entities became entitled,
pursuant to the Idanta Agreement, to request redemption of their shares upon the
delisting of the Company's Common Stock from the Nasdaq SmallCap Market. On
December 16, 1998, the Company
 
                                       39
<PAGE>
redeemed the Shares for an aggregate price of $4,648,000. 18,003 shares of
Series B Preferred Stock remain outstanding.
 
    On September 6, 1995, Mr. Sandfort, a director of the Company, was granted,
while an employee of the Company, a stock option to purchase 400,000 shares of
Common Stock at an exercise price of $6.81 per share, the fair market value of
the Common Stock on the date of such grant. On October 29, 1996, the Board of
Directors approved the exchange of the stock option held by Mr. Sandfort for an
option to purchase 400,000 shares of Common Stock at an exercise price of $1.63
per share, the fair market value of the Common Stock on such date. On July 28,
1997, the Board of Directors approved the exchange of the stock options held by
Mr. Sandfort for a warrant to purchase 57,595 shares of Common Stock (the vested
portion of his stock option) at an exercise price of $.47 per share, the fair
market value of the Common Stock on such date. On February 3, 1998, Mr. Sandfort
exercised the foregoing warrant by "cashless exercise" and purchased 38,770
shares of Common Stock.
 
    In June 1998, the Company and Siemens entered into a foundry agreement
pursuant to which Siemens manufactures and tests the Company's ProAsic products.
Unless extended by the parties, the term of the agreement expires in 2001. In
connection with the agreement, the Company issued to Siemens a warrant to
purchase up to 3,523,782 shares of Common Stock. Siemens also has the right to
acquire 500,000 shares of Common Stock pursuant to the License Agreement.
 
    The Company has entered into indemnity agreements with directors and certain
executive officers which provide, among other things, that the Company will
indemnify such officer or director, under the circumstances and to the extent
provided for therein, for expenses, damages, judgments, fines, witness fees and
settlements such officer or director may be required to pay in actions or
proceedings which he is or may be made a party by reason of his position as a
director, officer or other agent of the Company, and otherwise to the full
extent permitted under Delaware law and the Company's By-laws.

    1.  PURPOSES.

    Stock Awards are the Employees, Directors and Consultants of the Company and
    its Affiliates.
 
        (b)  AVAILABLE STOCK AWARDS.  The purpose of the Plan is to provide a
    means by which eligible recipients of Stock Awards may be given an
    opportunity to benefit from increases in value of the Common Stock through
    the granting of the following Stock Awards: (i) Incentive Stock Options,
    (ii) Nonstatutory Stock Options, and (iii) stock appreciation rights.
 
        (c)  GENERAL PURPOSE.  The Company, by means of the Plan, seeks to
    retain the services of the group of persons eligible to receive Stock
    Awards, to secure and retain the services of new members of this group and

    success of the Company and its Affiliates.

    either Directors of the Company who are not compensated by the Company for
    their services as Directors or Directors of the Company who are merely paid
    a director's fee by the Company for their services as Directors.

    in which the Participant renders service to the Company or an Affiliate as
    an Employee, Consultant or Director or a change in the entity for which the
    Participant renders such service, provided that there is no interruption or
    termination of the Participant's Continuous Service. For example, a change
    in status from an Employee of the Company to a Consultant of an Affiliate or
    a Director of the Company will not constitute an interruption of Continuous
    Service. The Board or the chief executive officer of the Company, in that
    party's sole discretion, may determine whether Continuous Service shall be
    considered interrupted in the case of any leave of absence approved by that
    party, including sick leave, military leave or any other personal leave.

       shares with respect to which a Stock Award shall be granted to each such
       person.
 
            (ii) 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.
 
           (iii) To amend the Plan or a Stock Award as provided in Section 12.
 
            (iv) 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)  DELEGATION TO COMMITTEE.
 
                                       3
<PAGE>
           (i)  GENERAL.  The Board may delegate administration of the Plan to a
       Committee or Committees of one or more members of the Board, and the term
       "Committee" shall apply to any person or persons to whom such authority
       has been delegated. 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 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.
 
           (ii)  COMMITTEE COMPOSITION WHEN COMMON STOCK IS PUBLICLY TRADED.  At
       such time as the Common Stock is publicly traded, in the discretion of
       the Board, a Committee may consist solely of two or more Outside
       Directors, in accordance with Section 162(m) of the Code, and/or solely
       of two or more Non-Employee Directors, in accordance with Rule 16b-3.
       Within the scope of such authority, the Board or the Committee may (i)
       delegate to a committee of one or more members of the Board who are not
       Outside Directors, the authority to grant Stock Awards to eligible
       persons who are either (a) not then Covered Employees and are not
       expected to be Covered Employees at the time of recognition of income
       resulting from such Stock Award or (b) not persons with respect to whom
       the Company wishes to comply with Section 162(m) of the Code and/or (ii)
       delegate to a committee of one or more members of the Board who are not
       Non-Employee Directors the authority to grant Stock Awards to eligible
       persons who are not then subject to Section 16 of the Exchange Act.
 
    4. SHARES SUBJECT TO THE PLAN.
 
        (a)  SHARE RESERVE.  Subject to the provisions of Section 11 relating to
    adjustments upon changes in stock, the stock that may be issued pursuant to
    Stock Awards shall not exceed in the aggregate three million (3,000,000)
    shares of Common Stock.
 
        (b)  REVERSION OF SHARES TO THE SHARE RESERVE.  If any Stock Award shall
    for any reason expire or otherwise terminate, in whole or in part, without
    having been exercised in full, the stock not acquired under such Stock Award
    shall revert to and again become available for issuance under the Plan.
    Shares subject to stock appreciation rights exercised in accordance with the
    Plan shall not be available for subsequent issuance under the Plan. If any
    Common Stock acquired pursuant to the exercise of an Option shall for any
    reason be repurchased by the Company under an unvested share repurchase
    option provided under the Plan, the stock repurchased by the Company under
    such repurchase option shall not revert to and again become available for
    issuance under the Plan.
 
        (c)  SOURCE OF SHARES.  The stock subject to the Plan may be unissued
    shares or reacquired shares, bought on the market or otherwise.
 
    5.  ELIGIBILITY.
 
        (a)  ELIGIBILITY FOR SPECIFIC STOCK AWARDS.  Incentive Stock Options may
    be granted only to Employees. Stock Awards other than Incentive Stock
    Options may be granted to Employees, Directors and Consultants.
 
        (b)  TEN PERCENT STOCKHOLDERS.  No Ten Percent Stockholder shall be
    eligib4le for the grant of an Incentive Stock Option unless the exercise
    price of such Option is at least one hundred ten percent (110%) of the Fair
    Market Value of the Common 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)  SECTION 162(m) LIMITATION.  Subject to the provisions of Section 11
    relating to adjustments upon changes in stock, no employee shall be eligible
    to be granted Options and/or stock appreciation
 
                                       4
<PAGE>
    rights covering more than one million (1,000,000) shares of the Common Stock
    during 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. All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and a separate certificate or certificates will be issued for shares
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 Incentive Stock Option 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 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.  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, 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 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)
    as determined 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) by
    delivery to the Company of other Common Stock, according to a deferred
    payment or other arrangement (which may include, without limiting the
    generality of the foregoing, the use of other Common Stock) with the
    Participant or in any other form of legal consideration that may be
    acceptable to the Board; 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.
 
        (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
    provisions of this subsection 6(e), 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 shall be transferable to the extent provided in the Option
    Agreement. If the Nonstatutory Stock Option does
 
                                       5
<PAGE>
    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
    provisions of this subsection 6(f), 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 which 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 as
    to which an Option may be exercised.
 
        (h)  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 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
    Optionholder's Continuous Service (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, after termination, the
    Optionholder does not exercise his or her Option within the time specified
    in the Option Agreement, the Option shall terminate.
 
        (i)  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 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.
 
        (j)  DISABILITY OF OPTIONHOLDER.  In the event 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 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 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, after termination, the
    Optionholder does not exercise his or her Option within the time specified
    herein, the Option shall terminate.
 
        (k)  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 the 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 the Option Agreement) 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.
 
                                       6
<PAGE>
        (l)  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 subject to the Option prior to the vesting of such shares
    under the Option. Any unvested shares so purchased may be subject to an
    unvested share repurchase option in favor of the Company or to any other
    restriction the Board determines to be appropriate.
 
        (m)  RE-LOAD OPTIONS.  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. Any such Re-Load Option shall (i)
    provide for a number of shares equal to the number of shares surrendered as
    part or all of the exercise price of such Option; (ii) 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) 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.
 
    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
dollars ($100,000) annual limitation on exercisability of Incentive Stock
Options described in subsection 10(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 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. STOCK APPRECIATION RIGHT PROVISIONS.
 
        (a)  AUTHORIZED RIGHTS.  The following three types of stock appreciation
    rights shall be authorized for issuance under the Plan:
 
               (1)  TANDEM RIGHTS.  A "Tandem Right" means a stock appreciation
           right granted appurtenant to an Option which is subject to the same
           terms and conditions applicable to the particular Option grant to
           which it pertains with the following exceptions: The Tandem Right
           shall require the holder to elect between the exercise of the
           underlying Option for shares of Common Stock and the surrender, in
           whole or in part, of such Option for an appreciation distribution.
           The appreciation distribution payable on the exercise of the Tandem
           Right shall be in cash (or, if so provided, in an equivalent number
           of shares of Common Stock based on Fair Market Value on the date of
           the Option surrender) in an amount up to the excess of (A) the Fair
           Market Value (on the date of the Option surrender) of the number of
           shares of Common Stock covered by that portion of the surrendered
           Option in which the Optionholder is vested over (B) the aggregate
           exercise price payable for such vested shares.
 
               (2)  CONCURRENT RIGHTS.  A "Concurrent Right" means a stock
           appreciation right granted appurtenant to an Option which applies to
           all or a portion of the shares of Common Stock subject to the
           underlying Option and which is subject to the same terms and
           conditions applicable to the particular Option grant to which it
           pertains with the following exceptions: A Concurrent Right shall be
           exercised automatically at the same time the underlying Option is
           exercised with respect to the particular shares of Common Stock to
           which the Concurrent
 
                                       7
<PAGE>
           Right pertains. The appreciation distribution payable on an exercised
           Concurrent Right shall be in cash (or, if so provided, in an
           equivalent number of shares of Common Stock based on Fair Market
           Value on the date of the exercise of the Concurrent Right) in an
           amount equal to such portion as determined by the Board at the time
           of the grant of the excess of (A) the aggregate Fair Market Value (on
           the date of the exercise of the Concurrent Right) of the vested
           shares of Common Stock purchased pursuant to the underlying Option
           which have Concurrent Rights appurtenant to them over (B) the
           aggregate exercise price paid for such shares.
 
               (3)  INDEPENDENT RIGHTS.  An "Independent Right" means a stock
           appreciation right granted independently of any Option but which is
           subject to the same terms and conditions applicable to a Nonstatutory
           Stock Option with the following exceptions: An Independent Right
           shall be denominated in share equivalents. The appreciation
           distribution payable on the exercised Independent Right shall be not
           greater than an amount equal to the excess of (a) the aggregate Fair
           Market Value (on the date of the exercise of the Independent Right)
           of a number of shares of Company stock equal to the number of share
           equivalents in which the holder is vested under such Independent
           Right, and with respect to which the holder is exercising the
           Independent Right on such date, over (b) the aggregate Fair Market
           Value (on the date of the grant of the Independent Right) of such
           number of shares of Company stock. The appreciation distribution
           payable on the exercised Independent Right shall be in cash or, if so
           provided, in an equivalent number of shares of Common Stock based on
           Fair Market Value on the date of the exercise of the Independent
           Right.
 
           (ii)  RELATIONSHIP TO OPTIONS.  Stock appreciation rights appurtenant
       to Incentive Stock Options may be granted only to Employees. The "Section
       162(m) Limitation" provided in subsection 5(c) and any authority to
       reprice Options shall apply as well to the grant of stock appreciation
       rights.
 
           (iii)  EXERCISE.  To exercise any outstanding stock appreciation
       right, the holder shall provide written notice of exercise to the Company
       in compliance with the provisions of the Stock Award Agreement evidencing
       such right. Except as provided in subsection 5(c) regarding the "Section
       162(m) Limitation," no limitation shall exist on the aggregate amount of
       cash payments that the Company may make under the Plan in connection with
       the exercise of a stock appreciation right.
 
    8.  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 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.
 
    9.  USE OF PROCEEDS FROM STOCK.
 
    Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.
 
                                       8
<PAGE>
    10.  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 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 or other holder of Stock Awards 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 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 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 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 the stock subject to the Stock Award for the
    Participant'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
    (iii) 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 (iv) 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)  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
    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 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 (iii) delivering
    to the Company owned and unencumbered shares of the Common Stock.

    11.  ADJUSTMENTS UPON CHANGES IN STOCK.
 
        (a)  CAPITALIZATION ADJUSTMENTS.  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 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 stock subject to such
    outstanding Stock Awards. Such adjustments shall be made by the Board, 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 "without receipt of consideration" by the Company.)
 
        (b)  DISSOLUTION OR LIQUIDATION.  In the event of a dissolution or
    liquidation of the Company, then such Stock Awards shall be terminated if
    not exercised (if applicable) prior to such event.
 
        (c)  CHANGE IN CONTROL--ASSET SALE, MERGER, CONSOLIDATION OR REVERSE
    MERGER.  In the event of (1) a sale of substantially all of the assets of
    the Company, (2) a merger or consolidation in which the Company is not the
    surviving corporation or (3) 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, then any
    surviving corporation or acquiring corporation may assume any Stock Awards
    outstanding under the Plan or may substitute similar stock awards (including
    an award to acquire the same consideration paid to the stockholders in the
    transaction described in this subsection 11(c)) for those outstanding under
    the Plan. In the event any surviving corporation or acquiring corporation
    does not assume such Stock Awards or does not 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 such
    event. With respect to any other Stock Awards outstanding under the Plan,
    such Stock Awards shall terminate if not exercised (if applicable) prior to
    such event.
 
        (d)  CHANGE IN CONTROL--SECURITIES ACQUISITION.  In the event of an
    acquisition by any person, entity or group within the meaning of Section
    13(d) or 14(d) of the Exchange Act, or any comparable successor provisions
    (excluding any employee benefit plan, or related trust, sponsored or
    maintained by the Company or an Affiliate) of the beneficial ownership
    (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or
    comparable successor rule) of securities of the Company representing at
    least fifty percent (50%) of the combined voting power entitled to vote in
    the election of directors, then any such acquiring person, entity or group
    may assume any Stock Awards outstanding under the Plan or may substitute
    similar stock awards (including an award to acquire the same consideration
    paid to the stockholders in the transaction described in this subsection
    11(d)) for those outstanding under the Plan. In the event any such acquiring
    person, entity or group does not assume such Stock Awards or does not
    substitute similar stock awards for those outstanding under the Plan, then
    such Stock Awards shall continue in full force and effect.
 
    12.  AMENDMENT OF THE PLAN AND STOCK AWARDS.
 
        (a)  AMENDMENT OF PLAN.  The Board at any time, and from time to time,
    may amend the Plan. However, except as provided in Section 11 relating to
    adjustments upon changes in stock, no amendment shall be effective unless
    approved by the stockholders of the Company to the extent stockholder
    approval is necessary to satisfy the requirements of Section 422 of the
    Code, Rule 16b-3 or any Nasdaq or securities exchange listing requirements.
 
                                       10
<PAGE>
        (b)  STOCKHOLDER APPROVAL.  The Board may, in its sole discretion,
    submit any other amendment to the Plan for stockholder approval, including,
    but not limited to, amendments to the Plan intended to satisfy the
    requirements of 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.
 
        (d)  NO IMPAIRMENT OF RIGHTS.  Rights under any Stock Award granted
    before 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, that the rights under any Stock Award shall not be impaired by any
    such amendment unless (i) the Company requests the consent of the
    Participant and (ii) the Participant consents in writing.
 
    13.  TERMINATION OR SUSPENSION OF THE PLAN.
 
        (a)  PLAN TERM.  The Board may suspend or terminate the Plan at any
    time. Unless sooner terminated, the Plan shall terminate on the day before
    the tenth (10th) anniversary of the date the Plan is adopted by the Board or
    approved by the stockholders of the Company, whichever is earlier. No Stock
    Awards may be granted under the Plan while the Plan is suspended or after it
    is terminated.
 
        (b)  NO IMPAIRMENT OF RIGHTS.  Rights and obligations under any Stock
    Award granted while the Plan is in effect shall not be impaired by
    suspension or termination of the Plan, except with the written consent of
    the Participant.
 
    14.  EFFECTIVE DATE OF PLAN.
 
    The Plan shall become effective as determined by the Board, but no Stock
Award shall be exercised unless and until the Plan has been approved by the
stockholders of the Company, which approval shall be within twelve (12) months
before or after the date the Plan is adopted by the Board.

                             GATEFIELD CORPORATION
                             1999 STOCK OPTION PLAN
 
                               STOCK OPTION AGREEMENT
                   (INCENTIVE AND NONSTATUTORY STOCK OPTIONS)
 
    Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock
Option Agreement, Gatefield Corporation (the "Company") has granted you an
option under its 1999 Stock Option 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.
 
        (a) Subject to the limitations contained herein, the shares covered by
    your option will vest (and become exercisable) as provided in your Grant
    Notice, provided that vesting will cease upon the termination of your
    Continuous Service.
 
        (b) Notwithstanding any other provision of this Stock Option Agreement
    or of the Plan to the contrary, in the event of the occurrence of a
    transaction described in subsections 11(c) or 11(d) of the Plan (hereafter,
    a "Change in Control") and if this option remains in effect following such
    Change in Control or if this option is assumed or a similar option
    substituted for this option in connection with a Change in Control, then the
    vesting and exercisability of the shares covered by this option (or by any
    substituted option) shall accelerate so that fifty percent (50%) of any
    unvested shares covered by this option shall immediately vest and become
    exercisable upon the effective date of the Change in Control. The remaining
    fifty percent (50%) of the unvested shares covered by this option (or by any
    substituted option) shall vest and become exercisable in accordance with the
    original schedule for vesting and exercisability (as provided in the Grant
    Notice), but in no event shall such remaining period of vesting be longer
    than two (2) years from the effective date of the Change in Control.
    Moreover, if your Continuous Service is terminated without Cause (as defined
    below) or you voluntarily terminate your Continuous Service due to a
    Constructive Termination (as defined below) within one (1) month prior to
    the effective date of the Change in Control or within six (6) months
    following the effective date of the Change in Control, then all remaining
    unvested shares covered by this option (or by any substituted option) shall
    vest and become exercisable as of the date of such termination.
 
    For purposes of this subparagraph 1(b) only, Cause means (i) conviction of,
a guilty plea with respect to, or a plea of NOLO CONTENDERE to a charge that you
have committed a felony under the laws of the United States or of any state or a
crime involving moral turpitude, including, but not limited to, fraud, theft,
embezzlement or any crime that results in or is intended to result in personal
enrichment at the expense of the Company or an Affiliate; (ii) material breach
of any agreement entered into between you and the Company or an Affiliate that
impairs the Company's or the Affiliate's interest therein; (iii) willful
misconduct, significant failure by you to perform your duties, or gross neglect
by you of your duties; or (iv) engagement in any activity that constitutes a
material conflict of interest with the Company or any Affiliate.
 
    For purposes of this subparagraph 1(b) only, Constructive Termination means
the occurrence of any of the following events or conditions: (i) (A) a change in
your status, title, position or responsibilities (including reporting
responsibilities) which represents an adverse change from your status, title,
position or responsibilities as in effect at any time within ninety (90) days
preceding the date of a Change in Control or at any time thereafter; (B) the
assignment to you of any duties or responsibilities which are inconsistent with
your status, title, position or responsibilities as in effect at any time within
ninety (90) days preceding
 
                                       1
<PAGE>
the date of a Change in Control or at any time thereafter; or (C) any removal of
you from or failure to reappoint or reelect you to any of such offices or
positions, except in connection with the termination of the your Continuous
Service for Cause, as a result of the your Disability or death or by you other
than as a result of Constructive Termination; (ii) a reduction in your annual
base compensation or any failure to pay you any compensation or benefits to
which you are entitled within five (5) days of the date due; (iii) the Company's
requiring you to relocate to any place outside a twenty (20) mile radius of your
current work site, except for reasonably required travel on the business of the
Company or its Affiliates which is not materially greater than such travel
requirements prior to the Change in Control; (iv) the failure by the Company to
(A) continue in effect (without reduction in benefit level and/or reward
opportunities) any material compensation or employee benefit plan in which you
were participating at any time within ninety (90) days preceding the date of a
Change in Control or at any time thereafter, unless such plan is replaced with a
plan that provides substantially equivalent compensation or benefits to you, or
(B) provide you with compensation and benefits, in the aggregate, at least equal
(in terms of benefit levels and/or reward opportunities) to those provided for
under each other employee benefit plan, program and practice in which you were
participating at any time within ninety (90) days preceding the date of a Change
in Control or at any time thereafter; (v) any material breach by the Company of
any provision of an agreement between the Company and you, whether pursuant to
this Plan or otherwise, other than a breach which is cured by the Company within
fifteen (15) days following notice by you of such breach; or (vi) the failure of
the Company to obtain an agreement from any successors and assigns to assume and
agree to perform the obligations created under the Plan.
 
        (c) Notwithstanding, subparagraph 1(b) above, in the event the potential
    acceleration of vesting and exercisability of the shares covered by this
    option would cause a contemplated Change in Control transaction that would
    otherwise be accounted for as a "pooling-of-interests" transaction to become
    ineligible for such accounting treatment under generally accepted accounting
    principles as determined by the Company's independent public accountants
    (the "Accountants") prior to the Change in Control, such acceleration shall
    not occur.
 
        (d) Notwithstanding any other provision of this paragraph (1) to the
    contrary, in the event that the acceleration of the vesting and
    exercisability of the shares covered by this option as provided for in this
    Stock Option Agreement and benefits otherwise payable to you (i) constitute
    "parachute payments" within the meaning of Section 280G (as it may be
    amended or replaced) of the Code and (ii) but for this subparagraph 1(d)
    would be subject to the excise tax imposed by Section 4999 (as it may be
    amended or replaced) of the Code (the "Excise Tax"), then your benefits
    hereunder shall be delivered to such lesser extent which would result in no
    portion of such benefits being subject to the Excise Tax; PROVIDED, HOWEVER,
    that the benefits hereunder shall be reduced only to the extent necessary
    only after all cash and all restricted stock otherwise payable to you and
    which constitute "parachute payments" have been returned. Unless the Company
    and you otherwise agree in writing, any determination required under this
    subparagraph 1(d) shall be made in writing in good faith by the Accountants.
    For purposes of making the calculations required by this subparagraph 1(d),
    the Accountants may make reasonable assumptions and approximations
    concerning applicable taxes and may rely on reasonable, good faith
    interpretations concerning the application of the Code. The Company and you
    shall furnish to the Accountants such information and documents as the
    Accountants may reasonably request in order to make a determination under
    this subparagraph 1(d). The Company shall bear all costs the Accountants may
    reasonably incur in connection with any calculations contemplated by this
    subparagraph 1(d).
 
    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
 
                                       2
<PAGE>
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 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, pursuant to a program developed under the rules and
    regulations 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, 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) and 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:
 
            (i) 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.
 
            (ii) 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
<PAGE>
           (iii) 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.
 
            (iv) In order to elect the deferred payment alternative if allowed,
       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
       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.  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 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.
 
    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.
 
                                       4
<PAGE>
        (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.
 
    9.  TRANSFERABILITY.  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.
 
    10.  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.
 
    11.  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.
 
    12.  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 the rules and regulations
    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 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.
 
                                       5
<PAGE>
        (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

    Stock from any escrow provided for herein.

                             GATEFIELD CORPORATION
                       1999 EMPLOYEE STOCK PURCHASE PLAN
 
                              ADOPTED JANUARY 26, 1999
               APPROVED BY THE STOCKHOLDERS ON            , 1999
                          EFFECTIVE DATE: JUNE 1, 1999
 
    1.  PURPOSE.
 
        (a) The purpose of this 1999 Employee Stock Purchase Plan (the "Plan")
    is to provide a means by which employees of Gatefield Corporation, a
    Delaware corporation (the "Company"), and its Affiliates, as defined in
    subparagraph 1(b), which are designated as provided in subparagraph 2(b),
    may be given an opportunity to purchase stock of the Company.
 
        (b) The word "Affiliate" as used in the Plan means any parent
    corporation or subsidiary corporation of the Company, as those terms are
    defined in Sections 424(e) and (f), respectively, of the Internal Revenue
    Code of 1986, as amended (the "Code").
 
        (c) The Company, by means of the Plan, seeks to retain the services of
    its employees, to secure and retain the services of new employees, and to
    provide incentives for such persons to exert maximum efforts for the success
    of the Company.
 
        (d) The Company intends that the rights to purchase stock of the Company
    granted under the Plan be considered options issued under an "employee stock
    purchase plan" as that term is defined in Section 423(b) of the Code.
 
    2.  ADMINISTRATION.
 
        (a) The Plan shall be administered by the Board of Directors (the
    "Board") of the Company unless and until the Board delegates administration
    to a committee as provided in subparagraph 2(c). Whether or not the Board
    has delegated administration the Board shall have the final power to
    determine all questions of policy and expediency that may arise in the
    administration of the Plan.
 
        (b) The Board shall have the power, subject to, and within the
    limitations of, the express provisions of the Plan:
 
            (i) To determine when and how rights to purchase stock of the
       Company shall be granted and the provisions of each offering of such
       rights (which need not be identical).
 
            (ii) To designate from time to time which Affiliates of the Company
       shall be eligible to participate in the Plan.
 
           (iii) To construe and interpret the Plan and rights 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, in a manner and to the
       extent it shall deem necessary or expedient to make the Plan fully
       effective.
 
            (iv) To amend the Plan as provided in paragraph 13.
 
            (v) Generally, to exercise such powers and to perform such acts as
       the Board or the Committee deems necessary or expedient to promote the
       best interests of the Company and its Affiliates and to carry out the
       intent that the Plan be treated as an "employee stock purchase plan"
       within the meaning of Section 423 of the Code.
 
        (c) The Board may delegate administration of the Plan to a committee
    composed of not fewer than two (2) members of the Board (the "Committee").
    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, subject, however, to such resolutions, not
    inconsistent with the
 
                                       1
<PAGE>
    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.
 
    3.  SHARES SUBJECT TO THE PLAN.
 
        (a) Subject to the provisions of paragraph 12 relating to adjustments
    upon changes in stock, the stock that may be sold pursuant to rights granted
    under the Plan shall not exceed in the aggregate one million (1,000,000)
    shares of the Company's common stock (the "Common Stock"). If any right
    granted under the Plan shall for any reason terminate without having been
    exercised, the Common Stock not purchased under such right shall again
    become available for the Plan.
 
        (b) The stock subject to the Plan may be unissued shares or reacquired
    shares, bought on the market or otherwise.
 
    4.  GRANT OF RIGHTS; OFFERING.
 
        (a) The Board or the Committee may from time to time grant or provide
    for the grant of rights to purchase Common Stock of the Company under the
    Plan to eligible employees (an "Offering") on a date or dates (the "Offering
    Date(s)") selected by the Board or the Committee. Each Offering shall be in
    such form and shall contain such terms and conditions as the Board or the
    Committee shall deem appropriate, which shall comply with the requirements
    of Section 423(b)(5) of the Code that all employees granted rights to
    purchase stock under the Plan shall have the same rights and privileges. The
    terms and conditions of an Offering shall be incorporated by reference into
    the Plan and treated as part of the Plan. The provisions of separate
    Offerings need not be identical, but each Offering shall include (through
    incorporation of the provisions of this Plan by reference in the document
    comprising the Offering or otherwise) the period during which the Offering
    shall be effective, which period shall not exceed twenty-seven (27) months
    beginning with the Offering Date, and the substance of the provisions
    contained in paragraphs 5 through 8, inclusive.
 
        (b) If an employee has more than one right outstanding under the Plan,
    unless he or she otherwise indicates in agreements or notices delivered
    hereunder: (1) each agreement or notice delivered by that employee will be
    deemed to apply to all of his or her rights under the Plan, and (2) a right
    with a lower exercise price (or an earlier-granted right, if two rights have
    identical exercise prices), will be exercised to the fullest possible extent
    before a right with a higher exercise price (or a later-granted right, if
    two rights have identical exercise prices) will be exercised.
 
    5.  ELIGIBILITY.
 
        (a) Rights may be granted only to employees of the Company or, as the
    Board or the Committee may designate as provided in subparagraph 2(b), to
    employees of any Affiliate of the Company. Except as provided in
    subparagraph 5(b), an employee of the Company or any Affiliate shall not be
    eligible to be granted rights under the Plan unless, on the Offering Date,
    such employee has been in the employ of the Company or any Affiliate for
    such continuous period preceding such grant as the Board or the Committee
    may require, but in no event shall the required period of continuous
    employment be equal to or greater than two (2) years. In addition, unless
    otherwise determined by the Board or the Committee and set forth in the
    terms of the applicable Offering, no employee of the Company or any
    Affiliate shall be eligible to be granted rights under the Plan unless, on
    the Offering Date, such employee's customary employment with the Company or
    such Affiliate is for at least twenty (20) hours per week and at least five
    (5) months per calendar year.
 
        (b) The Board or the Committee may provide that each person who, during
    the course of an Offering, first becomes an eligible employee of the Company
    or designated Affiliate will, on a date or dates specified in the Offering
    which coincides with the day on which such person becomes an eligible
    employee or occurs thereafter, receive a right under that Offering, which
    right shall thereafter be
 
                                       2
<PAGE>
    deemed to be a part of that Offering. Such right shall have the same
    characteristics as any rights originally granted under that Offering, as
    described herein, except that:
 
            (i) the date on which such right is granted shall be the "Offering
       Date" of such right for all purposes, including determination of the
       exercise price of such right;
 
            (ii) the period of the Offering with respect to such right shall
       begin on its Offering Date and end coincident with the end of such
       Offering; and
 
           (iii) the Board or the Committee may provide that if such person
       first becomes an eligible employee within a specified period of time
       before the end of the Offering, he or she will not receive any right
       under that Offering.
 
        (c) No employee shall be eligible for the grant of any rights under the
    Plan if, immediately after any such rights are granted, such employee owns
    stock possessing five percent (5%) or more of the total combined voting
    power or value of all classes of stock of the Company or of any Affiliate.
    For purposes of this subparagraph 5(c), the rules of Section 424(d) of the
    Code shall apply in determining the stock ownership of any employee, and
    stock which such employee may purchase under all outstanding rights and
    options shall be treated as stock owned by such employee.
 
        (d) An eligible employee may be granted rights under the Plan only if
    such rights, together with any other rights granted under "employee stock
    purchase plans" of the Company and any Affiliates, as specified by Section
    423(b)(8) of the Code, do not permit such employee's rights to purchase
    stock of the Company or any Affiliate to accrue at a rate which exceeds
    twenty-five thousand dollars ($25,000) of fair market value of such stock
    (determined at the time such rights are granted) for each calendar year in
    which such rights are outstanding at any time.
 
        (e) Officers of the Company and any designated Affiliate shall be
    eligible to participate in Offerings under the Plan, provided, however, that
    the Board or the Committee may provide in an Offering that certain employees
    who are highly compensated employees within the meaning of Section
    423(b)(4)(D) of the Code shall not be eligible to participate.
 
    6.  RIGHTS; PURCHASE PRICE.
 
        (a) On each Offering Date, each eligible employee, pursuant to an
    Offering made under the Plan, shall be granted the right to purchase up to
    the number of shares of Common Stock of the Company purchasable with a
    percentage designated by the Board or the Committee not exceeding fifteen
    percent (15%) of such employee's Earnings (as defined by the Board for each
    Offering) during the period which begins on the Offering Date (or such later
    date as the Board or the Committee determines for a particular Offering) and
    ends on the date stated in the Offering, which date shall be no later than
    the end of the Offering. The Board or the Committee shall establish one or
    more dates during an Offering (the "Purchase Date(s)") on which rights
    granted under the Plan shall be exercised and purchases of Common Stock
    carried out in accordance with such Offering.
 
        (b) In connection with each Offering made under the Plan, the Board or
    the Committee may specify a maximum number of shares that may be purchased
    by any employee as well as a maximum aggregate number of shares that may be
    purchased by all eligible employees pursuant to such Offering. In addition,
    in connection with each Offering that contains more than one Purchase Date,
    the Board or the Committee may specify a maximum aggregate number of shares
    which may be purchased by all eligible employees on any given Purchase Date
    under the Offering. If the aggregate purchase of shares upon exercise of
    rights granted under the Offering would exceed any such maximum aggregate
    number, the Board or the Committee shall make a pro rata allocation of the
    shares available in as nearly a uniform manner as shall be practicable and
    as it shall deem to be equitable.
 
                                       3
<PAGE>
        (c) The purchase price of stock acquired pursuant to rights granted
    under the Plan shall be not less than the lesser of:
 
            (i) an amount equal to eighty-five percent (85%) of the fair market
       value of the stock on the Offering Date; or
 
            (ii) an amount equal to eighty-five percent (85%) of the fair market
       value of the stock on the Purchase Date.
 
    7.  PARTICIPATION; WITHDRAWAL; TERMINATION.
 
        (a) An eligible employee may become a participant in the Plan pursuant
    to an Offering by delivering a participation agreement to the Company within
    the time specified in the Offering, in such form as the Company provides.
    Each such agreement shall authorize payroll deductions of up to the maximum
    percentage specified by the Board or the Committee of such employee's
    Earnings (as defined by the Board for each Offering) during the Offering.
    The payroll deductions made for each participant shall be credited to an
    account for such participant under the Plan and shall be deposited with the
    general funds of the Company. A participant may reduce (including to zero)
    or increase such payroll deductions, and an eligible employee may begin such
    payroll deductions, after the beginning of any Offering only as provided for
    in the Offering. A participant may make additional payments into his or her
    account only if specifically provided for in the Offering and only if the
    participant has not had the maximum amount withheld during the Offering.
 
        (b) At any time during an Offering, a participant may terminate his or
    her payroll deductions under the Plan and withdraw from the Offering by
    delivering to the Company a notice of withdrawal in such form as the Company
    provides. Such withdrawal may be elected at any time prior to the end of the
    Offering except as provided by the Board or the Committee in the Offering.
    Upon such withdrawal from the Offering by a participant, the Company shall
    distribute to such participant all of his or her accumulated payroll
    deductions (reduced to the extent, if any, such deductions have been used to
    acquire stock for the participant) under the Offering, without interest, and
    such participant's right to acquire Common Stock under that Offering shall
    be automatically terminated. A participant's withdrawal from an Offering
    will have no effect upon such participant's eligibility to participate in
    any other Offerings under the Plan but such participant will be required to
    deliver a new participation agreement in order to participate in subsequent
    Offerings under the Plan.
 
        (c) Rights granted pursuant to any Offering under the Plan shall
    terminate immediately upon cessation of a participant's employment with the
    Company and any designated Affiliate, for any reason, and the Company shall
    distribute to such terminated employee all of his or her accumulated payroll
    deductions (reduced to the extent, if any, such deductions have been used to
    acquire stock for the terminated employee), under the Offering, without
    interest.
 
        (d) Rights granted under the Plan shall not be transferable by a
    participant other than by will or the laws of descent and distribution, or
    by a beneficiary designation as provided in paragraph 14, and during a
    participant's lifetime, shall be exercisable only by such participant.
 
    8.  EXERCISE.
 
        (a) On each date specified therefor in the relevant Offering ("Purchase
    Date"), each participant's accumulated payroll deductions and other
    additional payments specifically provided for in the Offering (without any
    increase for interest) will be applied to the purchase of whole shares of
    stock of the Company, up to the maximum number of shares permitted pursuant
    to the terms of the Plan and the applicable Offering, at the purchase price
    specified in the Offering. Unless otherwise provided for in the applicable
    Offering, no fractional shares shall be issued upon the exercise of rights
    granted under the Plan. The amount, if any, of accumulated payroll
    deductions remaining in each participant's account after the purchase of
    shares which is less than the amount required to purchase one share of
 
                                       4
<PAGE>
    stock on the final Purchase Date of an Offering shall be held in each such
    participant's account for the purchase of shares under the next Offering
    under the Plan, unless such participant withdraws from such next Offering,
    as provided in subparagraph 7(b), or is no longer eligible to be granted
    rights under the Plan, as provided in paragraph 5, in which case such amount
    shall be distributed to the participant after such final Purchase Date,
    without interest. The amount, if any, of accumulated payroll deductions
    remaining in any participant's account after the purchase of shares which is
    equal to the amount required to purchase whole shares of stock on the final
    Purchase Date of an Offering shall be distributed in full to the participant
    after such Purchase Date, without interest.
 
        (b) No rights granted under the Plan may be exercised to any extent
    unless the shares to be issued upon such exercise under the Plan (including
    rights granted thereunder) are covered by an effective registration
    statement pursuant to the Securities Act of 1933, as amended (the
    "Securities Act") and the Plan is in material compliance with all applicable
    state, foreign and other securities and other laws applicable to the Plan.
    If on a Purchase Date in any Offering hereunder the Plan is not so
    registered or in such compliance, no rights granted under the Plan or any
    Offering shall be exercised on such Purchase Date, and the Purchase Date
    shall be delayed until the Plan is subject to such an effective registration
    statement and such compliance, except that the Purchase Date shall not be
    delayed more than twelve (12) months and the Purchase Date shall in no event
    be more than twenty-seven (27) months from the Offering Date. If on the
    Purchase Date of any Offering hereunder, as delayed to the maximum extent
    permissible, the Plan is not registered and in such compliance, no rights
    granted under the Plan or any Offering shall be exercised then all payroll
    deductions accumulated during the Offering (reduced to the extent, if any,
    such deductions have been used to acquire stock) shall be distributed to the
    participants, without interest.
 
    9.  COVENANTS OF THE COMPANY.
 
        (a) During the terms of the rights granted under the Plan, the Company
    shall at all times keep available the number of shares of stock required to
    satisfy such rights.
 
        (b) The Company shall seek to obtain from each federal, state, foreign
    or other regulatory commission or agency having jurisdiction over the Plan
    such authority as may be required to issue and sell shares of stock upon
    exercise of the rights granted under the Plan. 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 rights unless and until such authority is obtained.
 
    10.  USE OF PROCEEDS FROM STOCK.
 
    Proceeds from the sale of stock to participants pursuant to rights granted
under the Plan shall constitute general funds of the Company.
 
    11.  RIGHTS AS A STOCKHOLDER.
 
    A participant shall not be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to rights granted under
the Plan unless and until the participant's shares acquired upon exercise of
rights hereunder are recorded in the books of the Company (or its transfer
agent).
 
    12.  ADJUSTMENTS UPON CHANGES IN STOCK.
 
        (a) If any change is made in the stock subject to the Plan, or subject
    to any rights granted under the Plan (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 other transaction not
    involving the receipt of consideration by the Company), the Plan and
    outstanding rights will be appropriately adjusted in the class(es) and
 
                                       5
<PAGE>
    maximum number of shares subject to the Plan and the class(es) and number of
    shares and price per share of stock subject to outstanding rights. Such
    adjustments shall be made by the Board or the 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: (1) a dissolution or liquidation of the Company;
    (2) a merger or consolidation in which the Company is not the surviving
    corporation; (3) 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; or (4) the acquisition
    by any person, entity or group within the meaning of Section 13(d) or 14(d)
    of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
    any comparable successor provisions (excluding any employee benefit plan, or
    related trust, sponsored or maintained by the Company or any Affiliate of
    the Company) of the beneficial ownership (within the meaning of Rule 13d-3
    promulgated under the Exchange Act, or comparable successor rule) of
    securities of the Company representing at least fifty percent (50%) of the
    combined voting power entitled to vote in the election of directors, then,
    as determined by the Board in its sole discretion (i) any surviving or
    acquiring corporation may assume outstanding rights or substitute similar
    rights for those under the Plan, (ii) such rights may continue in full force
    and effect, or (iii) participants' accumulated payroll deductions may be
    used to purchase Common Stock immediately prior to the transaction described
    above and the participants' rights under the ongoing Offering terminated.
 
    13.  AMENDMENT OF THE PLAN.
 
        (a) The Board or the Committee at any time, and from time to time, may
    amend the Plan. However, except as provided in paragraph 12 relating to
    adjustments upon changes in stock, no amendment shall be effective unless
    approved by the stockholders of the Company within twelve (12) months before
    or after the adoption of the amendment if such amendment requires
    stockholder approval in order for the Plan to obtain employee stock purchase
    plan treatment under Section 423 of the Code or to comply with the
    requirements of Rule 16b-3 promulgated under the Exchange Act.
 
        (b) The Board or the Committee may amend the Plan in any respect the
    Board or the Committee 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 employee stock purchase plans and/or to bring the Plan and/or rights
    granted under it into compliance therewith.
 
        (c) Rights and obligations under any rights granted before amendment of
    the Plan shall not be altered or impaired by any amendment of the Plan,
    except with the consent of the person to whom such rights were granted, or
    except as necessary to comply with any laws or governmental regulations, or
    except as necessary to ensure that the Plan and/or rights granted under the
    Plan comply with the requirements of Section 423 of the Code.
 
    14.  DESIGNATION OF BENEFICIARY.
 
        (a) A participant may file a written designation of a beneficiary who is
    to receive any shares and cash, if any, from the participant's account under
    the Plan in the event of such participant's death subsequent to the end of
    an Offering but prior to delivery to the participant of such shares and
    cash. In addition, a participant may file a written designation of a
    beneficiary who is to receive any cash from the participant's account under
    the Plan in the event of such participant's death during an Offering.
 
        (b) Such designation of beneficiary may be changed by the participant at
    any time by written notice in the form prescribed by the Company. In the
    event of the death of a participant and in the
 
                                       6
<PAGE>
    absence of a beneficiary validly designated under the Plan who is living at
    the time of such participant's death, the Company shall deliver such shares
    and/or cash to the executor or administrator of the estate of the
    participant, or if no such executor or administrator has been appointed (to
    the knowledge of the Company), the Company, in its sole discretion, may
    deliver such shares and/or cash to the spouse or to any one or more
    dependents or relatives of the participant, or if no spouse, dependent or
    relative is known to the Company, then to such other person as the Company
    may designate.
 
    15.  TERMINATION OR SUSPENSION OF THE PLAN.
 
        (a) The Board or the Committee in its discretion, may suspend or
    terminate the Plan at any time. No rights may be granted under the Plan
    while the Plan is suspended or after it is terminated.
 
        (b) Rights and obligations under any rights granted while the Plan is in
    effect shall not be altered or impaired by suspension or termination of the
    Plan, except as expressly provided in the Plan or with the consent of the
    person to whom such rights were granted, or except as necessary to comply
    with any laws or governmental regulation, or except as necessary to ensure
    that the Plan and/or rights granted under the Plan comply with the
    requirements of Section 423 of the Code.
 
    16.  EFFECTIVE DATE OF PLAN.
 
    The Plan shall become effective on June 1, 1999 (the "Effective Date"),
provided that the Plan has been approved by the stockholders of the Company
prior to the Effective Date.
