     This statement is furnished in connection with the solicitation by the
Board of Directors (the "Board") of Alpha-Beta Technology, Inc. (hereinafter the
"Company" or "Alpha-Beta") of proxies in the accompanying form to be used at the
Annual Meeting of Stockholders of the Company to be held at One Innovation

adjournments and postponements thereof (the "Annual Meeting"), for the purposes
set forth in the accompanying Notice of Annual Meeting. It is intended that this
statement and the proxies solicited hereby be mailed to stockholders on or
shortly after April 25, 1997. Any stockholder who signs and returns a proxy in
the form enclosed with this statement has the power to revoke the proxy at any
time before it is exercised by giving written notice to such effect to the Clerk
of the Company. A stockholder also may revoke a proxy by filing a duly executed
proxy bearing a later date or by appearing in person and voting by ballot at the
Annual Meeting. Any stockholder of record as of the record date stated below
attending the Annual Meeting may vote in person whether or not a proxy has been
previously given, but the presence (without further action) of a stockholder at
the Annual Meeting will not constitute revocation of a previously given proxy.
Proxies properly executed and received in time for the Annual Meeting will be
voted.
 
     The close of business on April 4, 1997 has been fixed as the record date
for the determination of the stockholders entitled to notice of, and to vote at,
the Annual Meeting. As of such date, 16,743,308 shares of Common Stock were
outstanding and entitled to be voted at the Annual Meeting. Each share of Common
Stock is entitled to one vote on all matters voted on at the Annual Meeting.
 
     The proxies in the accompanying form will be voted as specified, but if no
specification is made they will be voted in favor of the proposals set forth
herein. In the discretion of the proxy holders, the proxies also will be voted
for or against such other matters as may properly come before the Annual
Meeting. The Board of Directors is not aware that any other matters are to be
presented for action at the Annual Meeting.
 
     The Company will pay the entire expense of soliciting proxies for the
Annual Meeting. In addition to solicitations by mail, solicitations also may be
made by personal interview or telephone. Banks, brokerage houses, custodians,
nominees and other fiduciaries have been requested to forward proxy materials to
the beneficial owners of shares held of record by them and will be reimbursed
for their expenses.
 
     The Annual Report of the Company, including financial statements for the
fiscal year ended December 31, 1996, is being mailed to stockholders

STATEMENTS, MAY BE OBTAINED WITHOUT CHARGE BY WRITING TO THE DIRECTOR OF FINANCE

REPORT OF EXECUTIVE COMPENSATION COMMITTEE
 
  The Compensation Committee
 
     The Compensation Committee currently consists of Mr. Hoff and Dr. Canavan.
The Compensation Committee's responsibilities include: (i) reviewing the
performance of the Chief Executive Officer and the other executive officers of
the Company and making recommendations as to their cash and equity-based
compensation and benefits; (ii) issuing options and stock grants under the
Company's 1988 Stock Option and Grant Plan (hereinafter the "1988 Option Plan");
and (iii) making recommendations as to the compensation policies for the
Company's non-officer employees.
 
  Overall Objectives and Executive Compensation Philosophy
 
     The overall objectives of the Compensation Committee are to set the
Company's executive compensation policies and programs for the Company's senior
management so as to ensure that executive compensation is appropriately tied to
the Company's performance and that the Company is capable of attracting,
retaining and motivating executive officers and other key employees. The
Compensation Committee established the following principles by which to achieve
its overall objectives. First, the Compensation Committee determined that
executive officer base salaries should, in general, be set at levels which are
at or slightly below industry averages. Second, the Company's executive officers
should be eligible for performance-based annual cash bonuses which are
conditioned upon significant achievement by both the Company and the individual.
Third, the Compensation Committee determined that it is appropriate to grant
stock options on a discretionary basis to ensure that key executives are
properly motivated in terms of future performance. The Compensation Committee
also believes that any such stock option or other equity-based compensation
should involve long-term vesting to encourage long-term tenure and enhancement
of shareholder value.
 
     Upon the Compensation Committee's recommendations, the Company has adopted
a policy by which the performance and compensation of all executive officers and
key employees are reviewed annually at each calendar year end. In connection
with such review, the annual salary of such executive officers and other key
employees for the upcoming fiscal year is adjusted based upon a review of their
performance during the previous fiscal year, any new roles or responsibilities
undertaken during that year, a comparison of the Company's compensation packages
to those of comparable companies and consideration of the Company's performance
and financial condition. As part of the annual review, any annual cash bonus
awards would also be made on the basis of previously-established performance
guidelines and any annual stock option or grant awards would be made.
 
                                        8
<PAGE>   12
 
     For its 1996 annual compensation review, the Compensation Committee used a
comparison group of public biotechnology companies based upon company size. All
compensation data for this peer group was derived from a 1995 survey performed
by an independent compensation consulting agency. The Compensation Committee
also used a similar 1996 survey for the purposes of determining bonuses to be
paid for 1996. The members of the Compensation Committee also relied upon their
knowledge of the biotechnology industry and the general salary levels paid by
public biotechnology companies.
 
  Base Salary
 
     The Compensation Committee adjusted 1996 annual salaries for each of the
Company's executive officers. Such adjustments reflect an average increase for
the executive officer group of 8.6 percent. As part of these adjustments, two
officers who were promoted to vice president received salary adjustments
significantly greater than the average increase. In making these adjustments,
the Compensation Committee considered the fact that base compensation for the
Company's executive officers had not been increased in 1995 over 1994 levels,
and that the executive compensation survey used by the Committee concluded that
the Company's annual salaries were less than the competitive norm.
 
  Annual Bonus
 
     The Company previously established an annual bonus program for the
executive officers and key employees of the Company. Under this program, the
executive officers and key employees are eligible for annual bonuses based upon
the Committee's subjective assessment of each individual's attainment of his or
her performance goals as well as the Committee's assessment of the Company's
overall performance.
 
     For 1996, the Compensation Committee determined to award cash and option
bonuses to executive officers. In awarding bonuses, the Compensation Committee
considered the Company's attainment of significant milestones, including
achievements in clinical trials, research and development, and manufacturing, as
well as a successful equity financing. The Compensation Committee also
considered the fact that the executive compensation survey used by the Committee
concluded that the Company's overall cash compensation was, on average,
approximately 14% less than the competitive market average.
 
  Stock Options
 
     Under the 1988 Option Plan, stock options are granted to Directors,
officers, other employees, scientific advisers and consultants and other key
persons. In general, stock options are granted to the Company's executive
officers at the time of their hire, annually as part of the Compensation
Committee's year-end review and at such other times as the Compensation
Committee may deem appropriate, such as a promotion. The Compensation Committee
bases its stock option award decisions upon its comparison of comparable
biotechnology companies, its assessment of an individual's performance and
importance to the Company and its determination that valued employees should
have a significant amount of unvested options as a long-term incentive.
 
     Stock options are designed to align the interest of executives with those
of the shareholders. Stock options are granted to executive officers with an
exercise price equal to the fair market value of the common stock on the date of
grant and usually vest between three and five years. This approach is designed
to incentivize the executives to create long-term shareholder value, since the
full benefit of the compensation package cannot be realized unless stock price
appreciation occurs over a number of years.
 
     As part of its 1996 annual compensation review, the Compensation Committee
determined to award an aggregate of 440,000 stock options to various executive
officers and director-level and associate director-level employees of the
Company at year-end as part of the bonus program described above. In determining
the
 
                                        9
<PAGE>   13
 
number of option shares granted to individual executive officers, the
Compensation Committee considered the fact that the executive compensation
survey used by the Committee concluded that, for most senior level positions of
the Company, the amount of stock options granted was less to significantly less
than the competitive norm. The Committee also considered the factors described
above for the bonus program.
 
  CEO Compensation
 
     As discussed above, consistent with its treatment of the Company's other
executive officers, the Compensation Committee determined to increase Dr. Jamas'
annual salary for 1996 to $242,000. This salary level represents 76% of the
average 1996 annual base salary paid to chief executive officers in the
comparable group of public biotechnology companies used by the Compensation
Committee. In addition, Dr. Jamas received a cash bonus of $40,000 as a year-end
1996 bonus. Dr. Jamas also received stock options for 80,000 shares. Dr. Jamas'
total cash compensation represents 62% of the average total cash compensation of
chief executive officers compared with the survey group. In awarding a 1996
bonus, the Compensation Committee credited Dr. Jamas' leadership in helping to
achieve the significant milestones referenced above.

securities to file reports of ownership and changes in ownership with the SEC
and The Nasdaq National Market. Officers, Directors and greater than 10%
stockholders are required to furnish the Company with copies of all Section
16(a) forms they file. To the Company's knowledge, based solely on review of the
copies of such reports furnished to the Company and representations that no

           PROPOSAL II -- APPROVAL OF THE ALPHA-BETA TECHNOLOGY, INC.
                        1997 STOCK OPTION AND GRANT PLAN
 
     The Board adopted the Alpha-Beta Technology, Inc. 1997 Stock Option and
Grant Plan (the "1997 Option Plan") on April 23, 1997 to provide for an adequate
number of shares of Common Stock available for grant by the Company, as options
may no longer be granted under the 1988 Option Plan after March 3, 1998. As in
the case of the 1988 Option Plan, the 1997 Option Plan is intended to promote
the interests of the Company by providing incentives to attract, motivate and
retain the services of highly qualified persons necessary to the Company's
future growth and success. The Directors believe that the 1997 Option Plan is in
the best interests of the Company and recommend its approval by stockholders. As
of April 23, 1997, no awards have been granted under the 1997 Option Plan.
 
                                       13
<PAGE>   17
 
     As of March 31, 1997, the Company had granted options pursuant to the 1988
Option Plan to purchase an aggregate of 2,371,252 shares of Common Stock at a
weighted average exercise price of $8.32 per share, of which options to purchase
891,920 shares were then exercisable. During 1996, Incentive Options (as defined
below) to purchase an aggregate of 557,588 shares of Common Stock were granted
to certain employees, officers and Directors of the Company at a weighted
average exercise price of $9.75 per share. During 1996, Non-Qualified Options
(as defined below) to purchase an aggregate of 8,448 shares of Common Stock were
granted to certain employees, officers and Directors of the Company at a
weighted average exercise price of $12.12 per share.
 
     As of March 31, 1997, a total of 392,886 options granted pursuant to the
1988 Option Plan had been exercised. As of March 31, 1997, a total of 158,461
shares were available for future option grants or outright grants under the 1988
Option Plan. Based solely upon the closing price of the Company's Common Stock
on March 31, 1997, the maximum aggregate market value of the Common Stock
underlying the options outstanding and eligible for issuance under the 1988
Option Plan was $20,263,086.
 
     A total of (i) 837,165 shares of Common Stock plus (ii) 5 percent of the
total number of shares of Common Stock issued by the Company after December 31,
1996 have been reserved for issuance under the 1997 Option Plan, subject to
certain limitations on the number of shares of stock that may be the subject of
outright grants and Incentive Stock Options under the 1997 Option Plan. Based
solely upon the closing price of the Company's Common Stock as reported by The
Nasdaq National Market on April 16, 1997, the maximum aggregate market value of
the securities to be issued under the 1997 Option Plan is $7,325,194. The total
number of shares available under the 1997 Option Plan will be subject to
adjustment upon the occurrence of a stock dividend, stock split or other change
affecting the Common Stock. The 1997 Option Plan also provides that stock
options with respect to no more than 200,00 shares of Common Stock may be
granted to any one individual in any one calendar year. The shares of Common
Stock issued by the Company under the 1997 Option Plan may be authorized but
unissued shares, or shares reacquired by the Company. To the extent that awards
under the 1997 Option Plan do not vest or otherwise revert to the Company, the
shares of Common Stock represented by such awards may be the subject of
subsequent awards.
 
     The Company is seeking stockholder approval and ratification of the 1997
Option Plan in accordance with the requirements of The Nasdaq National Market
and in order to permit grants of stock options and unrestricted stock under the
1997 Option Plan. Options and other awards will not be granted under the 1997
Option Plan unless and until the 1997 Option Plan is approved by stockholders
(or will be granted subject to stockholder approval).
 
     THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL OF THE 1997
OPTION PLAN.
 
SUMMARY OF THE 1997 OPTION PLAN
 
     The following description of certain features of the 1997 Option Plan is
intended to be a summary only. The summary does not purport to be complete and
is qualified in its entirety by reference to the 1997 Option Plan, the full text
of which is attached hereto as Appendix A.
 
     Plan Administration; Eligibility.  The 1997 Option Plan is administered by
the Board or by a committee appointed by the Board. All members of such
committee must be "Non-Employee Directors" as that term is defined under the
rules promulgated by the Securities and Exchange Commission under the Exchange
Act, and "outside directors" as defined in Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated
thereunder. The Board or authorized committee will interpret and make any
determination under the 1997 Option Plan regarding any options or stock granted
thereunder.
 
                                       14
<PAGE>   18
 
     Persons eligible to participate in the 1997 Option Plan are officers,
employees, Directors who are not also employees of the Company or any subsidiary
("Independent Directors"), consultants, advisors and other key persons of the
Company and its subsidiaries upon whose judgment, initiative and efforts the
Company largely depends for the successful conduct of its business ("Eligible
Persons"), as selected from time to time by the Compensation Committee. The
Compensation Committee has full power to select from among the Eligible Persons
the individuals to whom awards will be granted, to make any combination of
awards to such individuals, and to determine the specific terms and conditions
of each award, subject to the provisions of the 1997 Option Plan.
 
     The Compensation Committee, in its discretion, may delegate to the Chief
Executive Officer of the Company part of the Compensation Committee's authority
and duties with respect to the granting of awards to individuals who are not
subject to Section 16 of the Exchange Act and are not "covered employees" within
the meaning of Section 162(m) of the Code.
 
     Stock Options.  The 1997 Option Plan permits the grant of options to
purchase Common Stock intended to qualify as incentive stock options ("Incentive
Options") under Section 422 of the Code and options that do not so qualify
("Non-Qualified Options"). The option exercise price of each Incentive Option
will be determined by the Compensation Committee but may not be less than 100%
of the fair market value of the Common Stock on the date of grant. The option
exercise price of each Non-Qualified Option shall be determined by the
Compensation Committee at the time of grant.
 
     In lieu of a director fee, an Independent Director may elect to receive
such fee in Non-Qualified Options with a fair market value equal to the director
fee as determined by the Black-Scholes Option pricing model, an accepted model
for stock option valuation.
 
     The term of each option will be fixed by the Compensation Committee and may
not exceed ten years from date of grant in the case of an Incentive Option. The
Compensation Committee will determine at what time or times each option may be
exercised and, subject to the provisions of the 1997 Option Plan, the period of
time, if any, after retirement, death, disability or termination of employment
during which options may be exercised. Options may be made exercisable in
installments and the exercisability of options may be accelerated by the
Compensation Committee.
 
     Upon exercise, the option exercise price must be paid in full either in
cash or by certified or bank check or other instrument acceptable to the
Compensation Committee or, if the Compensation Committee so permits, by delivery
of shares of Common Stock already owned by the optionee. The exercise price may
also be delivered to the Company by a broker pursuant to irrevocable
instructions to the broker from the optionee.
 
     To qualify as Incentive Options, options must meet additional federal tax
requirements, including limits on the value of shares subject to Incentive
Options which first become exercisable in any one calendar year, and a shorter
term and higher minimum exercise price in the case of certain large
stockholders.
 
     Amendments and Termination.  The Board may at any time amend or discontinue
the 1997 Option Plan and the Compensation Committee may at any time amend or
cancel outstanding awards for the purpose of satisfying changes in the law or
for any other lawful purpose. However, no action may be taken which adversely
affects any rights under outstanding options without the option holder's
consent. Further, amendments to the 1997 Option Plan may be subject to approval
by the Company's stockholders if and to the extent required by the Code, to
preserve the qualified status of Incentive Options.
 
     Change of Control Provisions.  The 1997 Option Plan provides that in the
event of a dissolution or liquidation of the Company, a merger, reorganization
or consolidation in which a majority of the outstanding voting power of the
Company is acquired by a third-party or a sale to a third-party of all or
substantially all of the Company's assets or Common Stock, options (whether or
not otherwise exercisable) will be accelerated,
 
                                       15
<PAGE>   19
 
unless provision is made in connection with such transaction for the assumption
or substitution of awards by the successor or entity with appropriate adjustment
to the number and kind of shares and, if appropriate, per share exercise prices.
 
TAX ASPECTS UNDER THE U.S. INTERNAL REVENUE CODE
 
     The following is a summary of the principal federal income tax consequences
of option grants under the 1997 Option Plan. It does not describe all federal
tax consequences under the 1997 Option Plan, nor does it describe state or local
tax consequences.
 
     Incentive Options.  Under the Code, an employee generally will not realize
taxable income by reason of the grant or the exercise of an Incentive Option. If
an employee exercises an Incentive Option and does not dispose of the shares
until after the later of (a) two years from the date the option was granted and
(b) one year from the date shares were transferred to the employee, the entire
gain, if any, recognized upon a sale or exchange of such shares should be
taxable to the employee as long-term capital gain, and the Company will not be
entitled to any deduction. The exercise of an Incentive Option, however, may
result in alternative minimum tax liability for the employee. If an employee
disposes of shares within such one-year or two-year period in a manner so as to
violate the holding period requirements (a "disqualifying disposition"), the
employee will realize ordinary income in the year of disposition, and the
Company generally will receive a corresponding deduction, in an amount generally
equal to the excess of (1) the lesser of (x) the amount realized on the sale or
exchange of such shares (if the disposition is by sale or exchange) and (y) the
fair market value of the shares on the date the option was exercised over (2)
the exercise price for the shares. Any additional gain recognized on the
disposition should be treated as long-term or short-term capital gain and any
loss generally will be treated as long-term or short-term capital loss,
depending upon the holding period of the stock. A disqualifying disposition
generally includes any sale, exchange, gift or transfer of legal title (other
than by pledge) of shares during either of the holding periods described above.
Special rules apply in certain cases, including transfer to the employee's
spouse, transfer to the employee's former spouse incident to divorce, and
transfer on death. Special rules apply if an employee surrenders shares of
Common Stock in payment of the exercise price of the Incentive Option.
 
     An Incentive Option that is exercised by an employee more than three months
after an employee's employment terminates will be treated as a Non-Qualified
Option for federal income tax purposes; provided that in the case of termination
by reason of disability, the three-month period is extended to one year, and in
the case of death during employment or within three months after termination,
the three-month limitation does not apply.
 
     Non-Qualified Options.  There are no federal income tax consequences to
either the optionee or the Company on the grant of a Non-Qualified Option. On
the exercise of a Non-Qualified Option, the optionee generally has taxable
ordinary income equal to the excess of the fair market value of the Common Stock
received on the exercise date over the option price of the shares. The
optionee's tax basis for the shares acquired upon exercise of a Non-Qualified
Option is increased by the amount of such taxable income. The Company generally
will be entitled to a federal income tax deduction in an amount equal to such
excess. Upon the sale of the shares acquired by exercise of a Non-Qualified
Option, the optionee generally will recognize long-term or short-term capital
gain or loss depending upon his or her holding period for such shares. Special
rules apply if an optionee surrenders shares of Common Stock in payment of the
exercise price of a Non-Qualified Option.
 
     Limitation on Company's Deductions.  As a result of Section 162(m) of the
Code, the Company's deduction for certain awards under the Plan may be limited
to the extent that the Chief Executive Officer or
 
                                       16
<PAGE>   20
 
other named executive officer whose compensation is required to be reported in
the Summary Compensation Table receives compensation (other than
performance-based compensation) in excess of $1 million a year.
 
NEW PLAN BENEFITS
 
     As of April 16, 1997, approximately 170 persons were eligible to
participate in the 1997 Option Plan. The number of options and shares of stock
to be granted under the 1997 Option Plan is undeterminable at this time as
grants of awards under the 1997 Option Plan are subject to the discretion of the
Compensation Committee.
 
                                 REQUIRED VOTE
 
     The presence in person or by proxy of at least a majority of the total
number of outstanding shares of the Common Stock of the Company is necessary to
constitute a quorum at the Annual Meeting for the transaction of business. A
quorum being present, Directors will be elected by a plurality of the votes cast
on such matter by the holders of Common Stock entitled to vote on the election
of Directors. A quorum being present, approval of the 1997 Option Plan requires
the affirmative vote of a majority of the votes cast on such matter by the
holders of Common Stock. In accordance with the provisions of Massachusetts law
and the Company's Articles of Organization and By-Laws, the Company will treat
abstentions and broker non-votes as present at the Annual Meeting solely for
purposes of determining whether or not a quorum exists. Accordingly, abstentions
and broker non-votes will not be considered to be voting on the matters as to
which such abstentions or broker non-votes exist and, thus, will not be counted
in determining whether such matters have been approved by a plurality of votes
cast, in the case of the election of Directors, or a majority of votes cast, in
the case of the proposal to approve the 1997 Option Plan, by the stockholders
who are voting on such matters.

           and Determine Awards

not less than two "Non-Employee Directors" within the meaning of Rule
16b-3(b)(3)(i) under the Act, or any successor definition under said rule. Each

to grant Awards consistent with the terms of the Plan, including the power and
authority:
 
          (i) to select the officers, employees, Independent Directors,
     consultants, advisors and key persons of the Company and its Subsidiaries
     to whom Awards may from time to time be granted;
 
          (ii) to determine the time or times of grant, and the extent, if any,

     combination of the foregoing, granted under the Plan to any one or more
     participants;

     Award;
 
          (iv) to determine and modify from time to time the terms and
     conditions, including restrictions, not inconsistent with the terms of the
     Plan, of any Award, which terms and conditions may differ among individual
     Awards and participants, and to approve the form of written instruments
     evidencing the Awards;
 
          (v) to accelerate at any time the exercisability or vesting of all or
     any portion of any Award and/or to include provisions in Awards providing
     for such acceleration;
 
          (vi) to impose any limitations on Awards granted under the Plan,
     including limitations on transfers, repurchase provisions and the like and
     to exercise repurchase rights or obligations;
 
          (vii) subject to the provisions of Section 5(a)(ii), to extend at any
     time the period in which Stock Options may be exercised;
 
          (viii) to determine at any time whether, to what extent, and under
     what circumstances Stock and other amounts payable with respect to an Award
     shall be deferred either automatically or at the election of the
     participant and whether and to what extent the Company shall pay or credit
     amounts constituting interest (at rates determined by the Committee) or
     dividends or deemed dividends on such deferrals; and
 
          (ix) at any time to adopt, alter and repeal such rules, guidelines and
     practices for administration of the Plan and for its own acts and
     proceedings as it shall deem advisable; to interpret the terms and
 
                                       A-2
<PAGE>   24
 
     provisions of the Plan and any Award (including related written
     instruments); to make all determinations it deems advisable for the
     administration of the Plan; to decide all disputes arising in connection
     with the Plan; and to otherwise supervise the administration of the Plan.
 
     All decisions and interpretations of the Committee shall be binding on all
persons, including the Company and Plan participants.
 
     (c) Delegation of Authority to Grant Awards.  The Committee, in its
discretion, may delegate to the Chief Executive Officer of the Company all or
part of the Committee's authority and duties with respect to the granting of
Stock Options at Fair Market Value, to individuals who are not subject to the
reporting and other provisions of Section 16 of the Act or "covered employees"
within the meaning of Section 162(m) of the Code. Any such delegation by the
Committee shall include a limitation as to the amount of Stock Options that may
be granted each year. The Committee may revoke or amend the terms of a
delegation at any time but such action shall not invalidate any prior actions of
the Committee's delegate or delegates that were consistent with the terms of the
Plan.
 
SECTION 3. Stock Issuable under The Plan; Mergers; Substitution
 
     (a) Stock Issuable.  The maximum number of shares of Stock reserved and
available for issuance under the Plan (whether pursuant to outright grants or
options) shall be such aggregate number of shares of Stock as does not exceed
the sum of (i) 837,165 shares; plus (ii) as of each June 30 and December 31
after December 31, 1996, an additional positive number equal to five percent
(5%) of the shares of Stock issued by the Company during that six month period;
provided, however, that the maximum number of shares of Stock for which
Incentive Stock Options may be granted under the Plan shall not exceed 837,165
shares, and the maximum number of shares of stock which may be the subject of
outright grants shall not exceed 100,000 shares. For purposes of the foregoing
limitations, the shares of Stock underlying any Awards which are forfeited,
canceled, reacquired by the Company, satisfied without the issuance of Stock or
otherwise terminated shall be added back to the shares of Stock available for
issuance under the Plan. Stock Options with respect to no more than 200,000
shares of Stock may be granted to any one individual participant during any one
calendar year period. The shares available for issuance under the Plan may be
authorized but unissued shares of Stock or shares of Stock reacquired by the
Company.
 
     (b) Recapitalizations.  Subject to Section 3(c), if, through or as a result
of any merger, consolidation, sale of all or substantially all of the assets of
the Company, reorganization, recapitalization, reclassification, stock dividend,
stock split, reverse stock split or other similar transaction, the outstanding
shares of Stock are increased or decreased or are exchanged for a different
number or kind of shares or other securities of the Company or any successor
company, or additional shares or new or different shares or other securities of
the Company or any successor Company or other non-cash assets are distributed
with respect to such shares of Stock or other securities, the Committee shall
make an appropriate or proportionate adjustment in (i) the maximum number of
shares reserved for issuance under the Plan, (ii) the number of Stock Options
that can be granted to any one individual participant, (iii) the number and kind
of shares or other securities subject to any then outstanding Awards under the
Plan, and (iv) the price for each share subject to any then outstanding Stock
Options under the Plan, without changing the aggregate exercise price (i.e., the
exercise price multiplied by the number of shares) as to which such Stock
Options remain exercisable. The adjustment by the Committee shall be final,
binding and conclusive. No fractional shares of Stock shall be issued under the
Plan resulting from any such adjustment, but the Committee in its discretion may
make a cash payment in lieu of fractional shares.
 
     (c) Mergers and Other Transactions.  In the case of (i) the dissolution or
liquidation of the Company, (ii) a merger, reorganization or consolidation in
which a majority of the outstanding voting power of the
 
                                       A-3
<PAGE>   25
 
Company is acquired by another person or entity (other than a holding company
formed by the Company), (iii) the sale of all or substantially all of the assets
of the Company to an unrelated person or entity, or (iv) the sale of all of the
Stock of the Company to an unrelated person or entity (in each case, a
"Transaction"), the Plan and all Awards granted hereunder shall terminate upon
the effectiveness of the Transaction, unless provision is made in connection
with the Transaction for the assumption of Awards heretofore granted, or the
substitution of such Awards with new Awards of the successor entity or parent
thereof, with appropriate adjustment as to the number and kind of shares and, if
appropriate, the per share exercise prices, as provided in Section 3(b) above.
In the event of such termination, each optionee shall be permitted, within a
specified period determined by the Committee, to exercise all outstanding
Options held by such optionee whether or not otherwise exercisable during such
period, subject to the consummation of the Transaction.
 
     (d) Substitute Awards.  The Committee may grant Awards under the Plan in
substitution for stock and stock based awards held by employees of another
corporation who become employees of the Company or a Subsidiary as the result of
a merger or consolidation of the employing corporation with the Company or a
Subsidiary or the acquisition by the Company or a Subsidiary of property or
stock of the employing corporation. The Committee may direct that the substitute
awards be granted on such terms and conditions as the Committee considers
appropriate in the circumstances.
 
SECTION 4. Eligibility
 
     Participants in the Plan will be such full and part-time officers and other
employees, Independent Directors, consultants, advisors and other key persons of
the Company and its Subsidiaries who are responsible for or contribute to the
management, growth or profitability of the Company and its Subsidiaries as are
selected from time to time by the Committee, in its sole discretion.
 
SECTION 5. Stock Options
 
     Any Stock Option granted under the Plan shall be pursuant to a stock option
agreement which shall be in such form as the Committee may from time to time
approve. Option agreements need not be identical.
 
     Stock Options granted under the Plan may be either Incentive Stock Options
or Non-Qualified Stock Options. Incentive Stock Options may be granted only to
employees of the Company or any Subsidiary that is a "subsidiary corporation"
within the meaning of Section 424(f) of the Code, including members of the Board
who are also employees of the Company or any such Subsidiary. Non-Qualified
Stock Options may be granted to officers, employees, Independent Directors,
consultants, advisors and other key persons of the Company and its Subsidiaries.
To the extent that any Option does not qualify as an Incentive Stock Option, it
shall be deemed a Non-Qualified Stock Option.
 
     No Incentive Stock Option shall be granted under the Plan after April 23,
2007.
 
     (a) Terms of Stock Options.  Stock Options granted under the Plan shall be
subject to the following terms and conditions and shall contain such additional
terms and conditions, not inconsistent with the terms of the Plan, as the
Committee shall deem desirable:
 
          (i) Exercise Price.  The exercise price per share for the Stock
     covered by an Incentive Stock Option shall be determined by the Committee
     at the time of grant but shall not be less than 100% of the Fair Market
     Value on the date of grant. If an employee owns or is deemed to own (by
     reason of the attribution rules applicable under Section 424(d) of the
     Code) more than 10% of the combined voting power of all classes of stock of
     the Company or any parent or subsidiary corporation and an Incentive Stock
     Option is granted to such employee, the option price of such Incentive
     Stock Option shall be not less than 110% of the Fair Market Value on the
     grant date. The purchase price per share of Stock covered
 
                                       A-4
<PAGE>   26
 
     by a Non-Qualified Stock Option shall be determined by the Committee at the
     time of grant and shall not be subject to the restrictions described in the
     preceding two sentences.
 
          (ii) Option Term.  The term of each Stock Option shall be fixed by the
     Committee, but no Incentive Stock Option shall be exercisable more than ten
     years after the date the option is granted. If an employee owns or is
     deemed to own (by reason of the attribution rules of Section 424(d) of the
     Code) more than 10% of the combined voting power of all classes of stock of
     the Company or any parent or subsidiary corporation and an Incentive Stock
     Option is granted to such employee, the term of such option shall be no
     more than five years from the date of grant.
 
          (iii) Exercisability; Rights of a Stockholder.  Stock Options shall
     become vested and exercisable at such time or times, whether or not in
     installments, as shall be determined by the Committee at or after the grant
     date; provided, however, that Stock Options granted in lieu of cash
     compensation shall be exercisable in full as of the grant date. The minimum
     number of shares with respect to which an option may be exercised at any
     one time shall be one hundred (100) shares, or such lesser number as is
     subject to exercise under the Stock Option at the time. The Committee may
     at any time accelerate the exercisability of all or any portion of any
     Stock Option. An optionee shall have the rights of a stockholder only as to
     shares acquired upon the exercise of a Stock Option and not as to
     unexercised Stock Options.
 
          (iv) Method of Exercise.  Stock Options may be exercised in whole or
     in part, by giving written notice of exercise to the Company, specifying
     the number of shares to be purchased. Payment of the purchase price may be
     made by one or more of the following methods:
 
             (A) In cash, by certified or bank check or other instrument
        acceptable to the Committee;
 
             (B) In the form of shares of Stock that are not then subject to
        restrictions under any Company plan and that have been held by the
        optionee free of such restrictions for at least six months, if permitted
        by the Committee in its discretion. Such surrendered shares shall be
        valued at Fair Market Value on the exercise date; or
 
             (C) By the optionee delivering to the Company a properly executed
        exercise notice together with irrevocable instructions to a broker to
        promptly deliver to the Company cash or a check payable and acceptable
        to the Company to pay the purchase price; provided that in the event the
        optionee chooses to pay the purchase price as so provided, the optionee
        and the broker shall comply with such procedures and enter into such
        agreements of indemnity and other agreements as the Committee shall
        prescribe as a condition of such payment procedure.
 
     Payment instruments will be received subject to collection. The delivery of
     certificates representing the shares of Stock to be purchased pursuant to
     the exercise of a Stock Option will be contingent upon receipt from the
     optionee (or a purchaser acting in his or her stead in accordance with the
     provisions of the Stock Option) by the Company of the full purchase price
     for such shares and the fulfillment of any other requirements contained in
     the Stock Option or applicable provisions of law.
 
          (v) Termination.  Stock Options shall terminate at such times as are
     specified in the relevant Award.
 
          (vi) Annual Limit on Incentive Stock Options.  To the extent required
     for "incentive stock option" treatment under Section 422 of the Code, the
     aggregate Fair Market Value (determined as of the time of grant) of the
     shares of Stock with respect to which Incentive Stock Options granted under
     this Plan and any other plan of the Company or its parent and subsidiary
     corporations become exercisable for the first time by an optionee during
     any calendar year shall not exceed $100,000. To the extent that any Stock
     Option exceeds this limit, it shall constitute a Non-Qualified Stock
     Option.
 
                                       A-5
<PAGE>   27
 
     (b) Grant of Options in Lieu of Director Fees.  Each Independent Director
may, pursuant to a written election delivered to the Company, receive all of
such Independent Director's cash retainer and other cash fees payable to such
Independent Director in respect of his or her attendance at any meetings of the
Board or any committee thereof ("Director Fees") in the form of Non-Qualified
Stock Options to purchase such number of shares of Stock having a present value
equal to the amount of such Director Fees as shall be determined in accordance
with the Black-Scholes option pricing model on the date or dates the Director
Fees would otherwise be paid in cash. All Non-Qualified Stock Options granted
under this Section 5(b) shall have a per share exercise price which is equal to
the per share Fair Market Value of the Stock on the date such Non-Qualified
Stock Options are granted. The Committee, in its discretion, may grant
additional Non-Qualified Stock Options to Independent Directors.
 
     (c) Non-transferability of Options.  No Stock Option shall be transferable
by the optionee otherwise than by will or by the laws of descent and
distribution and all Stock Options shall be exercisable, during the optionee's
lifetime, only by the optionee, or his or her guardian or legal representative.
Notwithstanding the foregoing, the Committee may provide in an option agreement
that the optionee may transfer, without consideration for the transfer, his or
her Non-Qualified Stock Options to members of his or her immediate family, to
trusts for the benefit of such family members, to partnerships in which such
family members are the only partners; or to charitable organizations; provided,
however, that the transferee agrees in writing with the Company to be bound by
the terms and conditions of this Plan and the applicable Option Agreement.
 
SECTION 6. Grants of Stock
 
     Grants of Stock may be made to any officers, employees, Independent
Directors, consultants, advisors and other key persons of the Company and its
Subsidiaries. As a condition precedent to the grant of Stock to any grantee
under the Plan, the grantee shall grant to the Company such repurchase rights on
the Stock which is the subject of the grant as the Committee shall deem
necessary or appropriate. The Committee may also impose such other terms and
conditions on the grant of any Stock under the Plan as it may determine.
 
SECTION 7. Tax Withholding
 
     (a) Payment by Participant.  Each participant shall, no later than the date
as of which the value of an Award or of any Stock or other amounts received
thereunder first becomes includable in the gross income of the participant for
federal income tax purposes, pay to the Company, or make arrangements
satisfactory to the Committee regarding payment of, any federal, state, or local
taxes of any kind required by law to be withheld with respect to such income.
The Company and its Subsidiaries shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
participant.
 
     (b) Payment in Stock.  Subject to approval by the Committee, a participant
may elect to have such tax withholding obligation satisfied, in whole or in
part, by (i) authorizing the Company to withhold from shares of Stock to be
issued pursuant to any Award a number of shares with an aggregate Fair Market
Value (as of the date the withholding is effected) that would satisfy the
withholding amount due, or (ii) transferring to the Company shares of Stock
owned by the participant with an aggregate Fair Market Value (as of the date the
withholding is effected) that would satisfy the withholding amount due.
 
SECTION 8. Transfer, Leave of Absence, Etc.
 
     For purposes of the Plan, the following events shall not be deemed a
termination of employment:
 
     (a) a transfer to the employment of the Company from a Subsidiary or from
the Company to a Subsidiary, or from one Subsidiary to another; or
 
                                       A-6
<PAGE>   28
 
     (b) an approved leave of absence for military service or sickness, or for
any other purpose approved by the Company, if the employee's right to
re-employment is guaranteed either by a statute or by contract or under the
policy pursuant to which the leave of absence was granted or if the Committee
otherwise so provides in writing.
 
SECTION 9. Amendments and Termination
 
     The Board may, at any time, amend or discontinue the Plan and the Committee
may, at any time, amend or cancel any outstanding Award for the purpose of
satisfying changes in law or for any other lawful purpose, but no such action
shall adversely affect rights under any outstanding Award without the holder's
consent. The Committee may provide substitute Awards at the same or reduced
exercise or purchase price or with no exercise or purchase price in a manner not
inconsistent with the terms of the Plan, but such price, if any, must satisfy
the requirements which would apply to the substitute or amended Award if it were
then initially granted under this Plan, but no such action shall adversely
affect rights under any outstanding Award without the holder's consent. If and
to the extent determined by the Committee to be required by the Code to ensure
that Incentive Stock Options granted under the Plan are qualified under Section
422 of the Code, Plan amendments shall be subject to approval by the Company
stockholders who are eligible to vote at a meeting of stockholders.
 
SECTION 10. Status of Plan
 
     With respect to the portion of any Award which has not been exercised and
any payments in cash, Stock or other consideration not received by a
participant, a participant shall have no rights greater than those of a general
creditor of the Company unless the Committee shall otherwise expressly determine
in connection with any Award or Awards.
 
SECTION 11. General Provisions
 
     (a) No Distribution; Compliance with Legal Requirements.  The Committee may
require each person acquiring Stock pursuant to an Award to represent to and
agree with the Company in writing that such person is acquiring the shares
without a view to distribution thereof.
 
     No shares of Stock shall be issued pursuant to an Award until all
applicable securities law and other legal and stock exchange or similar
requirements have been satisfied. The Committee may require the placing of such
stop-orders and restrictive legends on certificates for Stock and Awards as it
deems appropriate.
 
     (b) Other Compensation Arrangements; No Employment Rights.  Nothing
contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either
generally applicable or applicable only in specific cases. The adoption of this
Plan and the grant of Awards do not confer upon any employee any right to
continued employment with the Company or any Subsidiary.
