            PROXY STATEMENT FOR THE ANNUAL MEETING OF STOCKHOLDERS
                      TO BE HELD ON TUESDAY, MAY 12, 1998
 
  This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors (the "Board") of Banyan Systems Incorporated
(the "Company") for use at the Annual Meeting of Stockholders to be held at
the Westboro Marriott, 5400 Computer Drive, Westboro, Massachusetts on
Tuesday, May 12, 1998 at 3:00 p.m., local time, and at any adjournment or
adjournments of the meeting (the "Annual Meeting"). All proxies will be voted
in accordance with the stockholders' instructions, and if no choice is
specified, the proxies will be voted in favor of the matters set forth in the
accompanying Notice of Meeting. Any proxy may be revoked by a stockholder at
any time before its exercise by delivery of written revocation or a
subsequently dated proxy to the Clerk of the Company or by voting in person at
the Annual Meeting.
 
  At the close of business on April 1, 1998, the record date for the
determination of stockholders entitled to vote at the Annual Meeting, there
were outstanding and entitled to vote an aggregate of             shares of
Common Stock, $0.01 par value per share (the "Common Stock"), and 263,158
shares of Series A Convertible Preferred Stock, $0.01 par value per share (the
"Series A Preferred"). Holders of shares of Common Stock are entitled to one
vote per share. Holders of shares of Series A Preferred are entitled to one
vote for each share of Common Stock issuable as of the date of such vote upon
conversion of each share of Preferred Stock held (currently, ten votes per
share of Series A Preferred). The holders of Series A Preferred will vote
separately as a class for purposes of electing the Series A Preferred
Director. On all other matters submitted to the holders of shares of Common
Stock, such holders and the holders of shares of Series A Preferred vote
together as one class.
 
  The Company's Annual Report for 1997 was mailed to stockholders, along with
these proxy materials, on or about April 6, 1998.
 
  THE COMPANY WILL, UPON WRITTEN REQUEST OF ANY STOCKHOLDERS, PROVIDE WITHOUT
CHARGE A COPY OF ITS ANNUAL REPORT ON FORM 10-K, INCLUDING FINANCIAL
STATEMENTS AND FINANCIAL STATEMENT SCHEDULES, AS FILED WITH THE SECURITIES AND
EXCHANGE COMMISSION ON MARCH 31, 1998. REQUESTS SHOULD BE ADDRESSED TO THE
TREASURER OF THE COMPANY, 120 FLANDERS ROAD, WESTBORO, MASSACHUSETTS 01581.
 
VOTES REQUIRED
 
  Under the Company's Amended and Restated By-laws (the "By-laws"), the
holders of a majority of the number of votes represented by shares of capital
stock issued, outstanding and entitled to vote on any matter shall constitute
a quorum with respect to that matter at the Annual Meeting. Shares of capital
stock present in person or represented by proxy (including shares which
abstain or do not vote with respect to one or more of the matters presented
for stockholder approval) will be counted for purposes of determining whether
a quorum is present.
 
  The affirmative vote of the holders of a plurality of the votes cast by the
stockholders entitled to vote at the Annual Meeting is required for the
election of directors; provided that the holders of a majority of the shares
of Series A Preferred, voting as a separate class, are entitled pursuant to
the Company's Second Restated Articles of Organization, as amended (the
"Second Restated Articles"), to elect one director of the Company. The
<PAGE>
 
affirmative vote of the holders of a majority of the shares of Common Stock
and the shares of Series A Preferred outstanding and entitled to vote on the
matter is required for the approval of the amendment to the Second Restated
Articles. The affirmative vote of the holders of a majority of the shares of
capital stock present or represented and voting on the matter is required for
the approval of all other matters being presented for stockholder approval at
the Annual Meeting.
 
  Shares which abstain from voting as to a particular matter, and shares held
in "street name" by brokers or nominees who indicate on their proxies that
they do not have discretionary authority to vote such shares as to a
particular matter, will not be voted in favor of such matter, and will also
not be counted as votes cast or shares voting on such matter. Accordingly,
abstentions and "broker non-votes" will have the same effect as a vote against
the proposed amendment to the Second Restated Articles, but will have no
effect on the voting on the other matters being presented for stockholder
approval at the Annual Meeting.

nonstatutory options to purchase shares of Common Stock. During 1997, Messrs.
Baker, Burton, Hamilton, Richardson and Strohm were each granted an annual
option for 3,000 shares of Common Stock at an exercise price of $2.00 per
share. On March 5, 1998, in connection with his initial election as a
Director, Mr. Wadsworth received an option to purchase 15,000 shares of Common
Stock at an exercise price of $4.00 per share. On the date of the 1998 Annual
Meeting of Stockholders, each of the Company's non-employee directors will
receive an annual option to purchase 3,000 shares of Common Stock at an
exercise price equal to the fair market value on the date of grant.

    Committee Report on Repricing of Options."
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Messrs. Burton, Richardson and Strohm served as members of the Compensation
Committee during the Company's last fiscal year. In consideration of the
active operational involvement of Mr. Burton as Chairman of the Board of the
Company, in November 1996, the Company entered into an agreement with Burton
Technology Partners, Ltd. ("BTP"), a company wholly owned by Mr. Burton.
Pursuant to this agreement, BTP agreed to provide consulting and related
services to the Company at a cost to the Company of $2,000 per day of service
plus reasonable expenses. Such services are to be performed by Mr. Burton
unless otherwise agreed by the parties. The agreement is for a term of six
months beginning October 21, 1996, and automatically renews for successive
three-month periods unless terminated by either party. No such termination has
yet to be effected. During 1997, payments from the Company to BTP totalled
$77,138.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
 Mr. Ferry's Employment Agreement
 
  In February 1997, the Company entered into an Employment Agreement with Mr.
Ferry pursuant to which the Company and Mr. Ferry agreed that Mr. Ferry would
be employed by the Company as its President and Chief Executive Officer. The
Employment Agreement sets Mr. Ferry's compensation at a minimum of $350,000
per year with a minimum annual bonus of $150,000 based upon the achievement of
certain performance objectives determined by the Board of Directors. Under the
Employment Agreement, Mr. Ferry is also eligible to receive an additional
bonus of a minimum of $150,000 based upon the achievement of specified
financial goals detailed in the Employment Agreement. The terms of the
Employment Agreement also include a grant of a nonstatutory stock option to
purchase 1,000,000 shares of Common Stock at a per share exercise price of
$4.00 and an award of 200,000 shares of Common Stock at par value. In
addition, the Employment Agreement contains confidentiality and noncompetition
provisions.
 
 
                                       9
<PAGE>
 
  The Company may terminate the Employment Agreement upon six months written
notice to Mr. Ferry. If such termination occurs on or before February 4, 1999,
Mr. Ferry will receive a cash payment from the Company equal to the sum of
$500,000 plus the amount by which $925,000 exceeds the aggregate of salary and
bonuses paid to Mr. Ferry under the Employment Agreement. If such termination
occurs subsequent to February 4, 1999, Mr. Ferry will receive a cash payment
from the Company equal to the greater of $500,000 or the sum of salary and
bonus which would have been paid to Mr. Ferry if all performance related
criteria to his bonus payments had been met. Mr. Ferry may terminate the
Employment Agreement for good reason upon notice given within 60 days of the
occurrence of certain specified events generally relating to diminished
responsibility with the Company (or notice given within one year if such
events occur due to a change in control of the Company). Upon a change in
control of the Company, 50% of the unvested portion of the stock option
granted to Mr. Ferry under the Employment Agreement immediately becomes
vested.
 
  In June 1997, the Company and Mr. Ferry entered into an Amendment to the
Employment Agreement. Pursuant to the Amendment, the Company (i) accelerated
the schedule of payment of certain bonuses under the Employment Agreement,
(ii) reduced the per share exercise price of the stock option granted under
the Employment Agreement from $4.00 to $2.25, (iii) rescinded the 200,000
share Common Stock Award under the Employment Agreement and (iv) paid to Mr.
Ferry a cash bonus of $400,000. Additionally under the Amendment, the Company
agreed to grant an award of 160,000 shares of Common Stock at par value
subject to the condition that such issuance shall not be effected unless Mr.
Ferry remained in continuous employment at the Company through and including
January 2, 1998 and subject to the further condition that Mr. Ferry not, as of
such date, announce his intention to terminate his employment at the Company.
 
 Other
 
  In March 1997, the Company entered into Employment Letters with Messrs.
Burke and Warner, pursuant to which Employment Letters the Company agreed to
employ Messrs. Burke and Warner as its Senior Vice President, Worldwide Sales
and Service, and Senior Vice President, Product Management and Development,
respectively. These Employment Letters provide for salaries per annum and
stock options to purchase shares of Common Stock for Messrs. Burke and Warner,
respectively, as follows: $240,000 and 120,000 shares and $170,000 and 130,000
shares. Messrs. Burke and Warner's stock options were granted with a per share
exercise price of $2.688, which exercise price was adjusted to $2.25 in May
1997. See "Repricing of Options" and "Compensation Committee Report on
Repricing of Options." In the event of a change in control of the Company, 50%
of all unvested stock options under the Employment Letters immediately become
exercisable. In addition, the termination of Mr. Burke by the Company for any
reason except for cause accelerates the vesting of all of Mr. Burke's stock
options granted pursuant to his Employment Letter which would have become
fully vested in the subsequent nine months but for such termination. The
Employment Letters also contemplate annual bonus targets for Messrs. Burke and
Warner in the amounts of $160,000 and $70,000, respectively. Mr. Burke's
Employment Letter guarantees him a minimum bonus in his first year of
employment of $90,000. The Employment Letters all provide for the payment by
the Company of the difference between any outside earnings and the salary
formerly paid by the Company upon termination of the executive (i) by the
Company for any reason, except cause, or (ii) voluntarily by the executive
upon a material reduction in responsibilities. Such payments continue for a
period of nine months for Mr. Burke and for a period of six months for Mr.
Warner.
 
  In September 1997, Mr. Spaulding entered into a Senior Executive Termination
Benefits Agreement superseding a prior agreement which became effective in
January 1997. Pursuant to the September Agreement, Mr. Spaulding agreed to
remain employed with the Company during any specified change in control of the
 
                                      10
<PAGE>
 
Company, and the Company agreed to provide certain severance benefits to Mr.
Spaulding in the event his employment at the Company is terminated within one
year following a change in control of the Company or if his employment is
terminated for certain other reasons. In the event (i) Mr. Spaulding's
employment is terminated by the Company for any reason, including a change in
control, except for cause, or (ii) Mr. Spaulding voluntarily terminates his
employment at the Company within 60 days from the occurrence of a change in
control or a material reduction of responsibilities and after 60 days' prior
written notice to the Company of his intention to terminate his employment,
the Company will pay Mr. Spaulding for six months the difference between his
outside earnings, if any, and his base salary at the Company. In addition, in
the event of a change in control, 50% of all unvested stock options held by
Mr. Spaulding will become fully vested.
 
  In March 1998, HarbourVest Partners V-Direct Fund, L.P. ("Harbour Vest
Fund") purchased from the Company 263,158 shares of the Company's Series A
Preferred, warrants to purchase 65,790 shares of the Company's Series B
Convertible Preferred Stock and warrants to purchase 65,790 shares of the
Company's Series C Convertible Preferred Stock, for an aggregate purchase
price of $10,000,000. As of March 30, 1998, such shares of Series A Preferred
and the shares of Series B and Series C Convertible Preferred Stock issuable
upon exercise of such warrants were convertible into 3,947,380 shares of
Common Stock. Mr. Wadsworth is a managing director of HarbourVest Partners,
LLC, which is the managing member of HVP V-Direct Associates, L.L.C., a
general partner of HarbourVest Fund. See "Proposal 4. Approval of Amendment to
Second Restated Articles of Organization."

COMPENSATION COMMITTEE REPORT ON REPRICING OF OPTIONS
 
  Effective February 27, 1997, as part of an initiative to increase employee
support, recognition and reward, the Board of Directors approved a repricing
of all outstanding employee stock options granted from August 1992 through
April 1997 (other than a total of 316,820 options held by Messrs. Glidden and
Mahoney and Ms. Smith) to $3.80 per share, a 10% premium over the then fair
market value of the Common Stock. The Board felt that this repricing would
foster a work environment that encourages and motivates employees to perform
to their utmost potential. Recognizing that these considerations apply equally
to executive officers as to employees, and in appreciation of Mr. Spaulding's
contributions as Vice President, Finance, in facilitating the transition of
executive management, certain options held by Mr. Spaulding were included on
this repricing.
 
  Effective May 9, 1997, the Board approved an additional stock option
repricing to $2.25 per share, a 20% premium over the then fair market value of
the Common Stock, applicable to all outstanding employee stock options.
Appreciating the need to similarly provide incentives to the Company's
executive officers, options held by executive officers were also repriced. The
Board considered this repricing to be consistent with the Company's philosophy
of utilizing equity incentives to motivate and retain qualified employees and
felt the repricing was an important sign of appreciation for the efforts of
the employees through the Company's restructuring. The Board required
employees to remain employed at the Company until January 1, 1998 in order to
benefit from this repricing. Certain options held by Messrs. Burke, Spaulding
and Warner were included in this repricing.
 
  Effective June 13, 1997, the Board approved an amendment to the Employment
Agreement between Mr. Ferry and the Company. Pursuant to such amendment, the
stock options held by Mr. Ferry were repriced from $4.00 per share to $2.25
per share, a 14% premium over the then fair market value of the Common Stock.
Because of a decline in market value of the Common Stock, Mr. Ferry's
outstanding options were exercisable at a price that exceeded the market value
of the Common Stock. In view of this decline, and recognizing the vital
contributions of Mr. Ferry as President and Chief Executive Officer, including
leading the Company's restructuring efforts, the Compensation Committee
believed that it was important to regain the incentive intended to be provided
by Mr. Ferry's options.

SECTION 16(B) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
  Based solely on its review of copies of reports filed by reporting persons
of the Company ("Reporting Persons") pursuant to Section 16(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), or written
representations from certain Reporting Persons that no Form 5 filing was
required for such person, the Company believes that during 1997, all filings
required to be made by its Reporting Persons were timely made in accordance
with the requirements of the Exchange Act, except as follows: Messrs. Mahoney
and Strohm each filed a late Form 5 reporting his May 1997 stock option grant
under the Company's 1992 Director Stock Option Plan, as amended.

          REPORT OF COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION
 
  The Company's executive compensation program is administered by the
Compensation Committee, which is currently comprised of three directors who
are not employees of the Company. The Compensation Committee is responsible
for determining the compensation of each executive officer and recommending
such compensation to the Board of Directors.
 
  The Company's executive compensation program is designed to align executive
compensation with the Company's business objectives and individual performance
and to enable the Company to attract, retain and reward executive officers who
contribute, and are expected to continue to contribute, to the Company's long-
term success. In establishing executive compensation, the Compensation
Committee is generally guided by the following principles: (i) the total
compensation payable to executive officers should be competitive with the
compensation paid by comparable companies for officers in comparable
positions; (ii) individual compensation should include components that reflect
the performance of the individual, teamwork and the achievement of corporate
objectives; and (iii) the Company should strive to achieve equitable
relationships both between the compensation of individual officers and between
the compensation of officers and other employees throughout the organization.
 
  The compensation of the Company's executive officers, including the Chief
Executive Officer and the other Named Executive Officers, consists of a
combination of base salary, annual incentive bonuses and equity-based
compensation.
 
  Base Salary. The Compensation Committee subjectively determines the base
salary for all executives, including the Chief Executive Officer, by reviewing
the salaries for competitive positions in the Company's industry, the
historical compensation levels of the executives, the individual performance
of the executives in the preceding year and salary levels required by any
applicable employment agreements. In addition, officers whose primary
responsibilities are in the areas of sales and marketing are entitled to
receive commissions based on sales. In fixing the base salary of all executive
officers in 1997, the Compensation Committee reviewed a survey prepared for
the Company by an outside consultant showing salary data for companies with
revenues comparable to those of the Company. The survey contained information
obtained from a broad set of participating companies, including certain
companies contained in the CRSP Nasdaq Total Return Index for Nasdaq Computer
& Data Processing Service Stocks. The Compensation Committee considered the
data in such survey as a basis for its subjective assessment that the salaries
established by it for 1997, including the base salary of Mr. Ferry, were
comparable to the median salaries of executive officers of companies with
revenues similar to those of the Company.
 
  Annual Incentive Awards. During 1997, all of the Company's executive
officers were newly appointed to their positions with the Company. In
consideration of this, the Compensation Committee deemed it appropriate to
award executive bonuses outside of the Company's traditional bonus plans.
Bonuses payable to executives were determined by negotiations between the
particular executive and the Company during the appointment process and were
paid as a percentage of annualized base wages earned during the year. A
significant portion of all bonuses were based upon the achievement of Company
financial goals, in light of the Company's restructuring, as determined by the
Compensation Committee. The balance was based upon achievement of personal and
team objectives, as determined by the Compensation Committee or such person
designated by the Compensation Committee. The specific objectives established
for Mr. Ferry in 1997 included financial targets set by the Compensation
Committee for operating profit and cash balances. The weighting between total
 
                                      14
<PAGE>
 
Company financial goals versus personal and team goals varied by position at
the sole discretion of the Compensation Committee.
 
  Stock-Based Compensation. Awards of stock options under the Company's stock
option plans are designed to more fully align the long-term interests of the
Company's executives and its stockholders and to assist in the retention of
executives. The Compensation Committee selects the executive officers, if any,
to receive stock options and subjectively determines the number of shares
subject to each option. The size of option grants is generally intended by the
Compensation Committee to reflect the executive's position with the Company
and his contributions to the Company. The Compensation Committee considered
options awarded in prior years when determining options for 1997. Options are
generally granted at market value and thus will have value to an executive
only if the Company's stock price increases.
 
  The Company has also adopted the 1995 Employee Stock Purchase Plan, which is
available to all eligible employees of the Company, including executive
officers. This Plan generally permits employees, including executive officers,
to purchase shares of Common Stock, through payroll deductions, at a price
equal to 85% of the fair market value of the Common Stock at the beginning or
end of the applicable purchase period, whichever is lower.
 
  Compliance with Internal Revenue Code Section 162(m). The Company does not
believe that Section 162(m) of the Code, which disallows a tax deduction to
public companies for certain compensation in excess of $1 million paid to the
company's Chief Executive Officer and four other most highly compensated
executive officers, will generally have an effect on the Company. The
Committee intends to periodically review the potential consequences of Section
162(m) and may structure the performance-based portion of its executive
compensation to comply with certain exemptions in Section 162(m).

  The following graph compares the cumulative total shareholder return on the
Company's Common Stock with the cumulative return of (i) the CRSP Total Return
Index for the Nasdaq National Market (U.S.) (the "CRSP Nasdaq Index") and (ii)
the CRSP Nasdaq Total Return Industry Index for Nasdaq Computer & Data
Processing Service Stocks (the "CRSP Computer & Data Index"). This graph
assumes the investment of $100 on December 31, 1992, the date on which the
Company's Common Stock was first publicly traded, in the Company's Common
Stock, the CRSP Nasdaq Index and the CRSP Computer & Data Index and assumes
dividends are reinvested. Measurement points are the last trading days for the
fiscal years ending December 31, 1992, 1993, 1994, 1995, 1996 and 1997.

                   2. RATIFICATION AND APPROVAL OF AMENDMENT
                         TO 1992 STOCK INCENTIVE PLAN
 
  The Board of Directors believes that the continued growth and profitability
of the Company depends, in large part, upon the ability of the Company to
maintain a competitive position in attracting and retaining key personnel.
Pursuant to an amendment adopted at the 1995 Annual Meeting of Stockholders,
the Company is currently authorized to issue under its 1992 Stock Incentive
Plan, as amended (the "1992 Plan"), a total of 2,700,000 shares of Common
Stock (subject to adjustment for certain changes in the Company's
capitalization). As of December 31, 1997, the number of shares available for
future grant under the 1992 Plan was 802,256. Accordingly, on February 11,
1998 the Board adopted, subject to stockholder ratification and approval, an
amendment to the 1992 Plan increasing the number of shares of Common Stock
available for issuance under the 1992 Plan from 2,700,000 to 3,500,000 shares
(subject to adjustment for certain changes in the Company's capitalization).
 
  THE BOARD OF DIRECTORS BELIEVES THAT THE AMENDMENT TO THE 1992 PLAN IS IN
THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS A VOTE
FOR THIS PROPOSAL.
 
  Ratification and approval of the amendment to the 1992 Plan is conditioned
upon approval of Proposal 4, relating to an amendment to the Company's Second
Restated Articles increasing from 25,000,000 to 35,000,000 the number of
shares of Common Stock authorized for issuance by the Company. See "Proposal
4. Approval of Amendment to Second Restated Articles of Organization."
 
  The following is a brief summary of the provisions of the 1992 Plan. This
summary is qualified in all respects by reference to the full text of the 1992
Plan, copies of which are available upon request to the Treasurer of the
Company.
 
  On June 23, 1992, the Board of Directors adopted, and on July 24, 1992 the
stockholders approved, the 1992 Plan. The 1992 Plan provides for the grant of
incentive stock options, nonstatutory stock options, stock appreciation
rights, performance shares and awards of restricted stock and unrestricted
stock ("Awards"). No Awards other than incentive stock options and
nonstatutory stock options have been granted under the 1992 Plan. No Award may
be made under the 1992 Plan after June 23, 2002, but Awards previously granted
may extend beyond that date. The 1992 Plan may be sooner terminated by the
Board of Directors, which has the power to amend or terminate the 1992 Plan.
 
 Administration
 
  The 1992 Plan is administered by the Board of Directors of the Company and
the Compensation Committee of the Board of Directors. The Board has the
authority to adopt, amend and repeal the administrative rules, guidelines and
practices relating to the 1992 Plan and to interpret the provisions of the
1992 Plan. Pursuant to the terms of the 1992 Plan, the Board has appointed the
Compensation Committee to administer certain aspects of the 1992 Plan. No
amendment to the 1992 Plan may be made without stockholder approval if such
approval is necessary to comply with any applicable tax or regulatory
requirement, including any requirements for compliance with Rule 16b-3
promulgated under the Exchange Act.
 
 Incentive Stock Options and Nonstatutory Options.
 
  Optionees receive the right to purchase a specified number of shares of
Common Stock at some time in the future at an option price and subject to such
terms and conditions as are specified at the time of the grant. The
 
                                      17
<PAGE>
 
1992 Plan provides that the number of shares of Common Stock with respect to
which options may be granted to any employee may not exceed 300,000 during any
two consecutive calendar year period. Incentive stock options and options
which the Board or Compensation Committee intends to qualify as performance-
based compensation under Section 162(m) of the Code may not be granted at an
exercise price less than the fair market value of the Common Stock on the date
of grant (or less than 110% of the fair market value in the case of incentive
stock options granted to optionees holding 10% or more of the voting stock of
the Company). All other options may be granted at an exercise price which may
be less than, equal to or greater than the fair market value of the Common
Stock on the date of grant.
 
 Eligibility.
 
  All of the employees, officers, directors, consultants and advisors of the
Company and its subsidiaries who are expected to contribute to the Company's
future growth and success are eligible to participate in the 1992 Plan.
Incentive stock options, however, may only be granted to persons eligible to
receive incentive stock options under the Code. As of December 31, 1997, the
Company had 410 employees. On April 1, 1998, the closing sale price of the
Company's Common Stock on the Nasdaq National Market was $     .
 
  The granting of Awards under the 1992 Plan is discretionary, and the Company
cannot now determine the number or type of Awards to be granted in the future
to any particular person or group. The following table, however, sets forth
the benefits received under the 1992 Plan during 1997 by (i) the Named
Executive Officers, individually, (ii) all current executive officers, as a
group (the "Executive Group"), (iii) all current directors who are not
executive officers, as a group (the "Non-Executive Director Group"), and (iv)
all employees, including all current officers who are not executive officers,
as a group (the "Non-Executive Officer Employee Group").

(1) Lists principal position with the Company as of December 31, 1997.
(2) Represents the difference between the fair market value of the underlying
    shares of Common Stock on the date of grant and the exercise price of the
    options. Certain options granted in 1997 in connection with the repricing
    of prior options were granted at an exercise price in excess of the fair
    market value of the underlying shares of Common Stock on the date of
    grant. In such cases, a dollar value of zero, in lieu of a negative dollar
    value, is included in the individual and group totals in the above table.
(3) During 1997, Messrs. Ferry, Burke and Warner received options to purchase
    1,000,000, 120,000 and 130,000 shares, respectively. In addition, one
    other executive officer was granted options to purchase 50,000 shares.
    Such options were not granted under the 1992 Plan and, accordingly, are
    not included in this table.
 
 Federal Income Tax Consequences
 
  The following is a summary of the United States federal income tax
consequences that generally will arise with respect to stock options granted
under the Plan and with respect to the sale of Common Stock acquired under the
Plan. As no Awards other than incentive stock options and nonstatutory stock
options have been granted under the 1992 Plan, a discussion of the United
States federal income tax consequences of other types of Awards is not
included. Moreover, the following discussion does not address the tax
consequences that may arise with respect to any gift or disposition other than
by sale of Common Stock acquired under the Plan. For precise advice as to any
specific transaction or set of circumstances, participants should consult with
their own tax advisors. Participants should also consult with their own tax
advisors regarding the application of any state, local, and foreign taxes and
any federal gift, estate, and inheritance taxes. The Plan is not a qualified
plan under Section 401(a) of the Code.
 
  Incentive Stock Options. In general, a participant will not recognize
taxable income upon the grant or exercise of an incentive stock option.
Instead, a participant will recognize taxable income with respect to an
incentive stock option only upon the sale of Common Stock acquired through the
exercise of the option ("ISO Stock"). Nevertheless, in the case of a
participant who has not been an employee of the Company at all times
commencing on the date on which a particular option was granted (the "Grant
Date") and ending on the date that is three months before the date on which
the option is exercised (the "Exercise Date"), an option generally will be
treated as though it were a nonstatutory option and taxed as described below
under "Nonstatutory Options." Similarly, options will be treated as
nonstatutory options for purposes of the alternative minimum tax. While a
participant will pay alternative minimum tax only to the extent of the excess
of that tax over the participant's regular tax, the treatment of an option as
a nonstatutory option for purposes of the alternative minimum tax could create
such an excess.
 
  Generally, the tax consequences of selling ISO Stock will vary with the
length of time that the participant has owned the ISO Stock at the time it is
sold. If the participant sells ISO Stock after having owned it for at least
two years from the Grant Date and one year from the Exercise Date, then the
participant will recognize long-term capital gain in an amount equal to the
excess of the sale price of the ISO Stock over the exercise price.
 
  If the participant sells ISO Stock prior to having owned it for at least two
years from the Grant Date and one year from the Exercise Date (a
"Disqualifying Disposition"), then the participant generally will recognize
ordinary compensation income in an amount equal to the lesser of (i) the
excess of the fair market value of the ISO Stock on the Exercise Date over the
exercise price and (ii) the excess of the sale price of the ISO Stock over the
exercise price.
 
                                      19
<PAGE>
 
  A participant making a Disqualifying Disposition will also recognize capital
gain in an amount equal to any excess of the sale price of the ISO Stock over
the fair market value of the ISO Stock on the Exercise Date. This capital gain
will be a long-term capital gain if the participant has held the ISO Stock for
more than one year prior to the date of the sale and will be a short-term
capital gain if the participant has held the ISO Stock for a shorter period.
 
  If a participant sells ISO Stock for less than the exercise price, then the
participant will recognize capital loss equal to the excess of the exercise
price over the sale price of the ISO Stock. This capital loss will be a long-
term capital loss if the participant has held the ISO Stock for more than one
year prior to the date of the sale and will be a short-term capital loss if
the participant has held the ISO Stock for a shorter period.
 
  Nonstatutory Options. As in the case of an incentive stock option, a
participant will not recognize taxable income upon the grant of a nonstatutory
option. However, a participant generally will recognize ordinary compensation
income upon the exercise of a nonstatutory option in an amount equal to the
excess of the fair market value of the Common Stock acquired through the
exercise of the option (the "NSO Stock") on the Exercise Date over the
exercise price.
 
  A participant will have a tax basis for any NSO Stock equal to the exercise
price plus any income recognized upon the exercise of the option. Upon selling
NSO Stock, a participant generally will recognize capital gain or loss in an
amount equal to the difference between the sale price of the NSO Stock and the
participant's tax basis in the NSO Stock. This capital gain or loss will be a
long-term capital gain or loss if the participant has held the NSO Stock for
more than one year prior to the date of the sale and will be a short-term
capital gain or loss if the participant has held the NSO Stock for a shorter
period.
 
  Delivery of Common Stock Upon Exercise of Stock Options. Under certain
circumstances, the Plan permits a participant to exercise a stock option by
delivering to the Company Common Stock having a fair market value equal in
amount to the exercise price. The use of this method of exercise generally
will not alter the tax consequences described above, and it may enable a
participant to dispose of appreciated Common Stock without immediately
recognizing capital gain on the disposition. The participant's tax basis in
any shares of Common Stock delivered to the Company to exercise an option
generally will be carried over to an equal number of shares of Common Stock
acquired upon exercising the option. Nevertheless, participants should
consider that the delivery to the Company of ISO Stock or stock acquired
pursuant to the Company's employee stock purchase plan will constitute a
Disqualifying Disposition, having all of the adverse tax consequences
described above, if the holding period requirements described above are not
satisfied with respect to that stock.
 
  Maximum Income Tax Rates on Capital Gain and Ordinary Income. Long-term
capital gain will be taxable at a maximum rate of 20% if attributable to
Common Stock held for more than eighteen months and at a maximum rate of 28%
if attributable to Common Stock held for more than one year but not more than
eighteen months. Short-term capital gain and ordinary income will be taxable
at a maximum rate of 39.6%. Phaseouts of personal exemptions and reductions of
allowable itemized deductions at higher levels of income may result in
slightly higher marginal tax rates. Ordinary compensation income will also be
subject to a medicare tax and, under certain circumstances, a social security
tax.
 
  Tax Consequences to the Company. The grant of a stock option (absent a
Section 83(b) Election by the participant) under the Plan will have no tax
consequences to the Company. Moreover, in general, neither the exercise of an
incentive stock option acquired under the Plan nor the sale of any Common
Stock acquired under the Plan will have any tax consequences to the Company.
However, the Company generally will be entitled to a
 
                                      20
<PAGE>
 
business-expense deduction with respect to any ordinary compensation income
recognized by a participant under the Plan. Any such deduction will be subject
to the limitations of Section 162(m) of the Code.
 
  Withholding. Although a participant's Disqualifying Disposition of ISO Stock
will result in the recognition of ordinary compensation income, the Company
will have no withholding obligation with respect to that income. In contrast,
the Company will have a withholding obligation with respect to ordinary
compensation income recognized with respect to a nonstatutory option by a
participant who has been employed by the Company. The Company will require any
such participant to make arrangements to satisfy this withholding obligation.
 
                   3. RATIFICATION AND APPROVAL OF AMENDMENT
                     TO 1995 EMPLOYEE STOCK PURCHASE PLAN
 
  The 1995 Employee Stock Purchase Plan, as amended (the "Purchase Plan") was
adopted by the Board of Directors on July 21, 1995 and approved by the
stockholders on April 29, 1996. The purpose of the Purchase Plan is to provide
to employees of the Company an opportunity to acquire a proprietary interest
in the Company through the purchase of Common Stock, which the Board of
Directors believes will help the Company in attracting, retaining and
motivating qualified employees. The Company is currently authorized to issue
under the Purchase Plan a total of 750,000 shares of Common Stock. As of
February 1, 1998, there were 53 shares available for future issuance under the
Purchase Plan. Accordingly, on February 11, 1998, the Board of Directors
adopted, subject to stockholder approval, an amendment to the Purchase Plan
increasing the number of shares of Common Stock available for issuance under
the Purchase Plan from 750,000 to 1,050,000 shares.
 
  THE BOARD OF DIRECTORS BELIEVES THAT THE AMENDMENT TO THE PURCHASE PLAN IS
IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS A
VOTE FOR THIS PROPOSAL.
 
  The following is a brief summary of the provisions of the Purchase Plan.
This summary is qualified in all respects by reference to the full text of the
Purchase Plan, copies of which are available upon request to the Treasurer of
the Company.
 
 Description of Offerings
 
  The Purchase Plan is implemented through a series of offerings. The maximum
number of shares available in each offering is 225,000 shares. If less than
225,000 shares are purchased during an offering, the amount not purchased may
be carried over and made available during any subsequent offering. Offering
periods generally commence on each February 1 and August 1 and terminate on
the following July 31 and January 31, respectively, or on such other dates as
may be determined by the Board. To date, four offerings under the Purchase
Plan have been completed, in which the Company issued an aggregate of 749,947
shares of Common Stock. Subject to the ratification and approval by the
stockholders of this proposal, a new offering under the Purchase Plan
commenced on February 1, 1997. The Purchase Plan will terminate when the
maximum number of shares issuable under the Purchase Plan have been purchased
by participating employees.
 
  The price at which employees may purchase Common Stock in an offering is 85%
of the closing price of the Common Stock on the Nasdaq National Market on the
day the offering commences or on the day the offering terminates, whichever is
lower. An employee may elect to have up to 10% of his or her qualifying
compensation withheld for the purpose of purchasing stock under the Purchase
Plan. On the date an offering commences, each participating employee is deemed
to be granted an option to purchase up to the number of shares determined by
 
                                      21
<PAGE>
 
dividing 6% of such employee's annualized compensation for the immediately
prior six-month period by 85% of the fair market value of the Common Stock on
the date the offering commences. Unless the participant elects to withdraw
from the offering, each participant who continues to be employed by the
Company on the date such offering terminates is deemed to have exercised the
option and purchased on such date such number of shares (subject to the
maximum number covered by his or her option) as may be purchased with the
amount of his or her payroll deductions at the offering price. If the total
number of shares of Common Stock that would otherwise be purchased in the
offering with accumulated payroll deductions exceeds the number of shares
available during the offering, the available shares will be allocated on a pro
rata basis to participating employees. The maximum number of shares issuable
under the Purchase Plan and in each offering under the Purchase Plan will be
proportionately adjusted upon certain changes in the Company's capitalization,
such as a stock split or stock dividend.
 
 Administration
 
  Administrative authority over the Purchase Plan is vested in the Company's
Board of Directors, which may delegate such power to its Compensation
Committee. The Board of Directors has complete and final authority to make
rules and regulations for the administration of the Purchase Plan. The Board
of Directors of the Company may at any time terminate or amend the Purchase
Plan, except that no such amendment shall be made without approval of the
stockholders of the Company if such approval is required by Section 423 of the
Code or by Rule 16b-3 under the Exchange Act, and in no event may any
amendment be made that would cause the Purchase Plan to fail to comply with
Section 16 under the Exchange Act or Section 423 of the Code.
 
 Eligibility
 
  Any employee, including a director, is eligible to participate in an
offering if he or she is regularly employed by the Company or a designated
subsidiary for more than 20 hours a week and for more than five months in a
calendar year and is employed by the Company or a designated subsidiary on the
first day of the applicable offering. As of February 1, 1998, a total of 399
of the Company's employees were eligible to participate in the Purchase Plan.
 
                                      22
<PAGE>
 
  The purchase of shares under the Purchase Plan is discretionary, and the
Company can not now determine the number of shares to be purchased in the
future by any particular person or group. The following table, however, sets
forth the benefits received under the Purchase Plan during 1997 by (i) the
Named Executive Officers, individually, (ii) the Executive Group, (iii) the
Non-Executive Director Group and (iv) the Non-Executive Officer Employee
Group.

 Federal Income Tax Consequences
 
  Tax Consequences to Participants. In general, a participant will not
recognize taxable income upon enrolling in the Purchase Plan or upon
purchasing shares of Common Stock at the end of an offering. Instead, if a
participant sells Common Stock acquired under the Purchase Plan at a sale
price that exceeds the price at which the participant purchased the Common
Stock, then the participant will recognize taxable income in an amount equal
to the excess of the sale price of the Common Stock over the price at which
the participant purchased the Common Stock. A portion of that taxable income
will be ordinary income, and a portion may be capital gain.
 
  If the participant sells the Common Stock more than one year after acquiring
it and more than two years after the date on which the offering commenced (the
"Grant Date"), then the participant will be taxed as follows. If the sale
price of the Common Stock is higher than the price at which the participant
purchased the Common
 
                                      23
<PAGE>
 
Stock, then the participant will recognize ordinary compensation income in an
amount equal to the lesser of (i) fifteen percent of the fair market value of
the Common Stock on the Grant Date and (ii) the excess of the sale price of
the Common Stock over the price at which the participant purchased the Common
Stock.
 
  Any further income will be long-term capital gain. If the sale price of the
Common Stock is less than the price at which the participant purchased the
Common Stock, then the participant will recognize long-term capital loss in an
amount equal to the excess of the price at which the participant purchased the
Common Stock over the sale price of the Common Stock.
 
  If the participant sells the Common Stock within one year after acquiring it
or within two years after the Grant Date (a "Disqualifying Disposition"), then
the participant will recognize ordinary compensation income in an amount equal
to the excess of the fair market value of the Common Stock on the date that it
was purchased over the price at which the participant purchased the Common
Stock. The participant will also recognize capital gain in an amount equal to
the excess of the sale price of the Common Stock over the fair market value of
the Common Stock on the date that it was purchased, or capital loss in an
amount equal to the excess of the fair market value of the Common Stock on the
date that it was purchased over the sale price of the Common Stock. This
capital gain or loss will be a long-term capital gain or loss if the
participant has held the Common Stock for more than one year prior to the date
of the sale and will be a short-term capital gain or loss if the participant
has held the Common Stock for a shorter period.
 
  Tax Consequences to the Company. The offering of Common Stock under the
Purchase Plan will have no tax consequences to the Company. Moreover, in
general, neither the purchase nor the sale of Common Stock acquired under the
Purchase Plan will have any tax consequences to the Company except that the
Company will be entitled to a business-expense deduction with respect to any
ordinary compensation income recognized by a participant upon making a
Disqualifying Disposition. Any such deduction will be subject to the
limitations of Section 162(m) of the Code.
 
  Withholding. The amount that a participant elects to have deducted from his
or her base pay for the purchase of Common Stock under the Purchase Plan
constitutes taxable wages and is subject to withholding. Moreover, the Company
will have a withholding obligation with respect to ordinary compensation
income recognized by a participant upon making a Disqualifying Disposition.
The Company will require any affected participant to make arrangements to
satisfy this withholding obligation.
 
     4. APPROVAL OF AMENDMENT TO SECOND RESTATED ARTICLES OF ORGANIZATION
 
  On February 11, 1998, the Board of Directors adopted, subject to stockholder
approval, an amendment to the Company's Second Restated Articles providing for
an increase in the authorized number of shares of Common Stock from 25,000,000
shares to 35,000,000 shares (the "Charter Amendment"). As of January 31, 1998,
the Company had a total of 17,869,405 shares of Common Stock outstanding,
4,394,823 shares reserved for future issuance under the 1992 Plan, the
Purchase Plan, its 1992 Director Stock Option Plan, as amended, and other
stock option and warrant grants (collectively, the "Stock Plans").
 
  On March 5, 1998, the Company entered into a Preferred Stock and Warrant
Purchase Agreement (the "Purchase Agreement") with HarbourVest Fund pursuant
to which the Company issued and sold to HarbourVest Fund (i) 263,158 shares of
Series A Preferred for $9,900,000 and (ii) warrants to purchase up to 65,790
shares of its Series B Convertible Preferred Stock, $0.01 par value per share
(the "Series B Preferred"), with an exercise price of $45.00 per share, and up
to 65,790 shares of its Series C Convertible Preferred Stock $0.01 par
 
                                      24
<PAGE>
 
value per share (the "Series C Preferred"), with an exercise price of $50.00
per share, for an aggregate purchase price of $100,000. Each share of the
Company's Series A Preferred, Series B Preferred and Series C Preferred
presently is convertible at any time into ten shares of Common Stock. Without
stockholder approval of the Charter Amendment, the Company will not have a
sufficient number of shares of Common Stock to maintain reserves for the
shares of Common Stock issuable upon conversion of presently outstanding
shares of Series A Preferred and for the shares of Series B Preferred and
Series C Preferred issuable upon exercise of presently outstanding warrants.
Accordingly, in the event the Charter Amendment is not approved, the Company
will be required to redeem 40% of the 263,158 shares of the Series A Preferred
and 40% of each of the warrants issued to HarbourVest Fund, for an aggregate
redemption price of $4,000,000.
 
  If the Charter Amendment is approved, the additional authorized shares of
Common Stock would be available for issuance in the future for corporate
purposes, including without limitation, the aforementioned HarbourVest Fund
preferred stock financing and other financings, acquisitions, stock splits,
stock dividends and management incentive and employee benefit plans, as the
Board may deem advisable, without the necessity of further stockholder action.
The issuance of additional shares of Common Stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, would have the effect of diluting the Company's current stockholders
and could have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, control
of the Company. Other than in connection with the Stock Plans and the
HarbourVest Fund preferred stock financing, the Company has no present
intention or plans to issue any shares of Common Stock. The Company is not
aware of any attempts on the part of a third party to effect a change in
control of the Company, and the Charter Amendment has been proposed by the
Company for the reasons stated above and not for any possible anti-takeover
effects it may have.
 
  THE BOARD OF DIRECTORS BELIEVES THAT THE CHARTER AMENDMENT IS IN THE BEST
INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS A VOTE FOR THIS
PROPOSAL.
 
  Approval of the Charter Amendment is a condition to ratification and
approval of Proposal 2, relating to an increase from 2,700,000 to 3,500,000 of
the number of shares of Common Stock authorized for issuance under the 1992
Plan. See "Proposal 2. Ratification and Approval of Amendment to 1992 Stock
Incentive Plan".
 
            5. RATIFICATION OF SELECTION OF INDEPENDENT ACCOUNTANTS
 
  The Board of Directors, at the recommendation of the Audit Committee, has
selected the firm of Coopers & Lybrand L.L.P. as the Company's independent
accountants for the current fiscal year. Coopers & Lybrand L.L.P. has served
as the Company's independent accountants since inception. Although stockholder
approval of the Board of Directors' selection of Coopers & Lybrand L.L.P. is
not required by law, the Board of Directors believes that it is advisable to
give stockholders an opportunity to ratify this selection. If this proposal is
not approved at the Annual Meeting, the Board of Directors will reconsider its
selection of Coopers & Lybrand L.L.P.
 
  Representatives of Coopers & Lybrand L.L.P. are expected to be present at
the Annual Meeting and will have the opportunity to make a statement if they
desire to do so and will also be available to respond to appropriate questions
from stockholders.
 
  THE BOARD OF DIRECTORS BELIEVES THAT THE RATIFICATION OF COOPERS & LYBRAND
L.L.P. AS THE COMPANY'S INDEPENDENT AUDITORS FOR THE FISCAL YEAR 1998 IS IN
THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS A VOTE
FOR THIS PROPOSAL.

                                 OTHER MATTERS

for the Annual Meeting. Brokers, custodians and fiduciaries will be requested
to forward proxy soliciting material to the owners of stock held in their
names, and, as required by law, the Company will, at their request, reimburse
them for their out-of-pocket expenses in this regard.
 
                                          By Order of the Board of Directors,
 
                                          RICHARD M. SPAULDING, Vice President

respect of shares of Common Stock expires or is terminated unexercised or is
forfeited for any reason or settled in a manner that results in fewer shares
outstanding than were initially awarded, the shares subject to such Award or
so surrendered, as the case may be, to the extent of such expiration,
termination, forfeiture or decrease, shall again be available for award under
the Plan, subject, however, in the case of Incentive Stock Options, to any
limitation required under the Code. Shares issued under the Plan may consist
in whole or in part of authorized but unissued shares or treasury shares.
 
                                      B-2
<PAGE>
 
  (b) In the event that the Board, in its sole discretion, determines that any
stock dividend, extraordinary cash dividend, recapitalization, reorganization,
merger, consolidation, split-up, spin-off, combination or other similar
transaction affects the Common Stock such that an adjustment is required in
order to preserve the benefits or potential benefits intended to be made
available under the Plan, then the Board, subject, in the case of Incentive
Stock Options, to any limitation required under the Code, shall equitably
adjust any or all of (i) the number and kind of shares in respect of which
Awards may be made under the Plan, (ii) the number and kind of shares subject
to outstanding Awards, and (iii) the award, exercise or conversion price with
respect to any of the foregoing, and if considered appropriate, the Board may
make provision for a cash payment with respect to an outstanding Award,
provided that the number of shares subject to any Award shall always be a
whole number.
 
  (c) The Board may grant Awards under the Plan in substitution for stock and
stock based awards held by employees of another corporation who concurrently
become employees of the Company as a 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 substitute Awards shall be granted on such terms and
conditions as the Board considers appropriate in the circumstances. The shares
which may be delivered under such substitute Awards shall be in addition to
the maximum number of shares provided for in Section 5(a) only to the extent
that the substitute Awards are both (i) granted to persons whose relationship
to the Company does not make (and is not expected to make) them Reporting
Persons; and (ii) granted in substitution for awards issued under a plan
approved, to the extent then required under Rule 16b-3, by the stockholders of
the entity which issued such predecessor awards.
 
Section 6. Stock Options
 
 (a) General.
 
    (i) Subject to the provisions of the Plan, the Board may award Incentive
  Stock Options and Nonstatutory Stock Options, and determine the number of
  shares to be covered by each Option, the option price therefor and the
  conditions and limitations applicable to the exercise of the Option. The
  terms and conditions of Incentive Stock Options shall be subject to and
  comply with Section 422 of the Code, or any successor provision, and any
  regulations thereunder.
 
    (ii) The Board shall establish the exercise price at the time each Option
  is awarded. In the case of Incentive Stock Options, such price shall not be
  less than 100% of the Fair Market Value of the Common Stock on the date of
  award.
 
    (iii) Each Option shall be exercisable at such times and subject to such
  terms and conditions as the Board may specify in the applicable Award or
  thereafter. The Board may impose such conditions with respect to the
  exercise of Options, including conditions relating to applicable federal or
  state securities laws, as it considers necessary or advisable.
 
    (iv) Options granted under the Plan may provide for the payment of the
  exercise price by delivery of cash or check in an amount equal to the
  exercise price of such Options or, to the extent permitted by the Board at
  or after the award of the Option, by (A) delivery of shares of Common Stock
  owned by the optionee for at least six months (or such shorter period as is
  approved by the Board), valued at their Fair Market Value, (B) delivery of
  a promissory note of the optionee to the Company on terms determined by the
  Board, (C) delivery of an irrevocable undertaking by a broker to deliver
  promptly to the Company sufficient funds to pay the exercise price or
  delivery of irrevocable instructions to a broker to deliver promptly to the
  Company cash or a check sufficient to pay the exercise price, (D) payment
  of such other lawful consideration as the Board may determine, or (E) any
  combination of the foregoing.
 
                                      B-3
<PAGE>
 
    (v) The Board may provide for the automatic award of an Option upon the
  delivery of shares to the Company in payment of the exercise price of an
  Option for up to the number of shares so delivered.
 
    (vi) The Board may at any time accelerate the time at which all or any
  part of an Option may be exercised.
 
 (b) Incentive Stock Options.
 
  Options granted under the Plan which are intended to be Incentive Stock
Options shall be subject to the following additional terms and conditions:
 
    (i) All Incentive Stock Options granted under the Plan shall, at the time
  of grant, be specifically designated as such in the option agreement
  covering such Incentive Stock Options. The Option exercise period shall not
  exceed ten years from the date of grant.
 
    (ii) If any employee to whom an Incentive Stock Option is to be granted
  under the Plan is, at the time of the grant of such option, the owner of
  stock possessing more than 10% of the total combined voting power of all
  classes of stock of the Company (after taking into account the attribution
  of stock ownership rule of Section 424(b) and of the Code), then the
  following special provisions shall be applicable to the Incentive Stock
  Option granted to such individual:
 
      (x) The purchase price per share of the Common Stock subject to such
    Incentive Stock Option shall not be less than 110% of the Fair Market
    Value of one share of Common Stock at the time of grant; and
 
      (y) The option exercise period shall not exceed five years from the
    date of grant.
 
    (iii) For so long as the Code shall so provide, options granted to any
  employee under the Plan (and any other incentive stock option plans of the
  Company) which are intended to constitute Incentive Stock Options shall not
  constitute Incentive Stock Options to the extent that such options, in the
  aggregate, become exercisable for the first time in any one calendar year
  for shares of Common Stock with an aggregate Fair Market Value (determined
  as of the respective date or dates of grant) of more than $100,000.
 
    (iv) No Incentive Stock Option may be exercised unless, at the time of
  such exercise, the Participant is, and has been continuously since the date
  of grant of his or her Option, employed by the Company, except that:
 
      (x) an Incentive Stock Option may be exercised within the period of
    three months after the date the Participant ceases to be an employee of
    the Company (or within such lesser period as may be specified in the
    applicable option agreement), provided, that the agreement with respect
    to such Option may designate a longer exercise period and that the
    exercise after such three-month period shall be treated as the exercise
    of a Nonstatutory Stock Option under the Plan;
 
      (y) if the Participant dies while in the employ of the Company, or
    within three months after the Participant ceases to be such an
    employee, the Incentive Stock Option may be exercised by the
    Participant's Designated Beneficiary within the period of one year
    after the date of death (or within such lesser period as may be
    specified in the applicable Option agreement); and
 
      (z) if the Participant becomes disabled (within the meaning of
    Section 22(e)(3) of the Code or any successor provision thereto) while
    in the employ of the Company, the Incentive Stock Option may be
    exercised within the period of one year after the date of death (or
    within such lesser period as may be specified in the Option agreement).
 
                                      B-4
<PAGE>
 
For all purposes of the Plan and any Option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of
the Income Tax Regulations (or any successor regulations). Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.
 
Section 7. Stock Appreciation Rights
 
  (a) The Board may grant Stock Appreciation Rights entitling recipients on
exercise of the SAR to receive an amount, in cash or Stock or a combination
thereof (such form to be determined by the Board), determined in whole or in
part by reference to appreciation in the Fair Market Value of the Stock
between the date of the Award and the exercise of the Award. A Stock
Appreciation Right shall entitle the Participant to receive, with respect to
each share of Stock as to which the SAR is exercised, the excess of the
share's Fair Market Value on the date of exercise over its Fair Market Value
on the date the SAR was granted. The Board may also grant Stock Appreciation
Rights that provide that, following a change in control of the Company (as
defined by the Board at the time of the Award), the holder of such SAR will be
entitled to receive, with respect to each share of Stock subject to the SAR,
an amount equal to the excess of a specified value (which may include an
average of values) for a share of Stock during a period preceding such change
in control over the Fair Market Value of a share of Stock on the date the SAR
was granted.
 
  (b) Stock Appreciation Rights may be granted in tandem with, or
independently of, Options granted under the Plan. A Stock Appreciation Right
granted in tandem with an Option which is not an Incentive Stock Option may be
granted either at or after the time the Option is granted. A Stock
Appreciation Right granted in tandem with an Incentive Stock Option may be
granted only at the time the Option is granted.
 
  (c) When Stock Appreciation Rights are granted in tandem with Options, the
following provisions will apply:
 
    (i) The Stock Appreciation Right will be exercisable only at such time or
  times, and to the extent, that the related Option is exercisable and will
  be exercisable in accordance with the procedure required for exercise of
  the related Option.
 
    (ii) The Stock Appreciation Right will terminate and no longer be
  exercisable upon the termination or exercise of the related Option, except
  that a Stock Appreciation Right granted with respect to less than the full
  number of shares covered by an Option will not be reduced until the number
  of shares as to which the related Option has been exercised or has
  terminated exceeds the number of shares not covered by the Stock
  Appreciation Right.
 
    (iii) The Option will terminate and no longer be exercisable upon the
  exercise of the related Stock Appreciation Right.
 
    (iv) The Stock Appreciation Right will be transferable only with the
  related Option.
 
    (v) A Stock Appreciation Right granted in tandem with an Incentive Stock
  Option may be exercised only when the market price of the Stock subject to
  the Option exceeds the exercise price of such option.
 
  (d) A Stock Appreciation Right not granted in tandem with an Option will
become exercisable at such time or times, and on such conditions, as the Board
may specify.
 
  (e) The Board may at any time accelerate the time at which all or any part
   of the SAR may be exercised.
 
                                      B-5

Section 8. Performance Shares
 
  (a) The Board may make Performance Share Awards entitling recipients to
acquire shares of Stock upon the attainment of specified performance goals.
The Board may make Performance Share Awards independent of or in connection
with the granting of any other Award under the Plan. The Board in its sole
discretion shall determine the performance goals applicable under each such
Award, the periods during which performance is to be measured, and all other
limitations and conditions applicable to the awarded Performance Shares;
provided, however, that the Board may rely on the performance goals and other
standards applicable to other performance plans of the Company in setting the
standards for Performance Share Awards under the Plan.
 
  (b) Performance Share Awards and all rights with respect to such Awards may
not be sold, assigned, transferred, pledged or otherwise encumbered.
 
  (c) A Participant receiving a Performance Share Award shall have the rights
of a stockholder only as to shares actually received by the Participant under
the Plan and not with respect to shares subject to an Award but not actually
received by the Participant. A Participant shall be entitled to receive a
stock certificate evidencing the acquisition of shares of Stock under a
Performance Share Award only upon satisfaction of all conditions specified in
the agreement evidencing the Performance Share Award.
 
  (d) The Board may at any time accelerate or waive any or all of the goals,
restrictions or conditions imposed under any Performance Share Award.
 
Section 9. Restricted and Unrestricted Stock
 
  (a) The Board may grant Restricted Stock Awards entitling recipients to
acquire shares of Stock, subject to the right of the Company to repurchase all
or part of such shares at their purchase price (or to require forfeiture of
such shares if purchased at no cost) from the recipient in the event that
conditions specified by the Board in the applicable Award are not satisfied
prior to the end of the applicable Restricted Period or Restricted Periods
established by the Board for such Award. Conditions for repurchase (or
forfeiture) may be based on continuing employment or service or achievement of
pre-established performance or other goals and objectives.
 
  (b) Shares of Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered, except as permitted by the Board, during the
applicable Restricted Period. Shares of Restricted Stock shall be evidenced in
such manner as the Board may determine. Any certificates issued in respect of
shares of Restricted Stock shall be registered in the name of the Participant
and, unless otherwise determined by the Board, deposited by the Participant,
together with a stock power endorsed in blank, with the Company (or its
designee). At the expiration of the Restricted Period, the Company (or such
designee) shall deliver such certificates to the Participant or if the
Participant has died, to the Participant's Designated Beneficiary.
 
  (c) The Board may, in its sole discretion, grant (or sell at a purchase
price determined by the Board, which shall not be lower than 85% of Fair
Market Value on the date of sale) to Participants shares of Stock free of any
restrictions under the Plan ("Unrestricted Stock").
 
  (d) The purchase price for each share of Restricted Stock and Unrestricted
Stock shall be determined by the Board of Directors and may not be less than
the par value of the Common Stock. Such purchase price may be paid in the form
of past services or such other lawful consideration as is determined by the
Board.
 
  (e) The Board may at any time accelerate the expiration of the Restricted
Period applicable to all, or any particular, outstanding shares of Restricted
Stock.

<PAGE>
 
Section 10. General Provisions Applicable to Awards
 
  (a) Applicability of Rule 16b-3. Those provisions of the Plan which make an
express reference to Rule 16b-3 shall apply to the Company only at such time
as the Company's Common Stock is registered under the Securities Exchange Act
of 1934, or any successor provision, and then only to Reporting Persons.
 
  (b) Reporting Person Limitations. Notwithstanding any other provision of the
Plan, to the extent required to qualify for the exemption provided by Rule
16b-3, (i) any Option, SAR, Performance Share Award or other similar right
related to an equity security issued under the Plan to a Reporting Person
shall not be transferable other than by will or the laws of descent and
distribution or pursuant to a qualified domestic relations order as defined by
the Code or Title I or the Employee Retirement Income Security Act ("ERISA"),
or the rules thereunder, and shall be exercisable during the Participant's
lifetime only by the Participant or the Participant's guardian or legal
representative, and (ii) the selection of a Reporting Person as a Participant
and the terms of his or her Award shall be determined only in accordance with
the applicable provisions of Rule 16b-3.
 
  (c) Documentation. Each Award under the Plan shall be evidenced by an
instrument delivered to the Participant specifying the terms and conditions
thereof and containing such other terms and conditions not inconsistent with
the provisions of the Plan as the Board considers necessary or advisable. Such
instruments may be in the form of agreements to be executed by both the
Company and the Participant, or certificates, letters or similar documents,
acceptance of which will evidence agreement to the terms thereof and of this
Plan.
 
  (d) Board Discretion. Each type of Award may be made alone, in addition to
or in relation to any other type of Award. The terms of each type of Award
need not be identical, and the Board need not treat Participants uniformly.
Except as otherwise provided by the Plan or a particular Award, any
determination with respect to an Award may be made by the Board at the time of
award or at any time thereafter.
 
  (e) Termination of Status. Subject to the provisions of Section 6(b)(iv),
the Committee shall determine the effect on an Award of the disability, death,
retirement, authorized leave of absence or other termination of employment or
other status of a Participant and the extent to which, and the period during
which, the Participant's legal representative, guardian or Designated
Beneficiary may exercise rights under such Award.
 
  (f) Mergers, Etc. In the event of a consolidation, merger or other
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (as "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company, or the board of directors of
any corporation assuming the obligations of the Company, may, in its
discretion, take any one or more of the following actions as to outstanding
Awards: (i) provide that such Awards shall be assumed, or substantially
equivalent Awards shall be substituted, by the acquiring or succeeding
corporation (or an affiliate thereof) on such terms as the Board determines to
be appropriate, (ii) upon written notice to Participants, provide that all
unexercised Options or SARs will terminate immediately prior to the
consummation of such transaction unless exercised by the Participant within a
specified period following the date of such notice, (iii) in the event of an
Acquisition under the terms of which holders of the Common Stock of the
Company will receive upon consummation thereof a cash payment for each share
surrendered in the Acquisition (the "Acquisition Price"), make or provide for
a cash payment to Participants equal to the difference between (A) the
Acquisition Price times the number of shares of Common Stock subject to
outstanding Options or SARs (to the extent then exercisable at prices not in
excess of the Acquisition Price) and (B) the aggregate exercise price of all
such outstanding Options or SARs in exchange for the termination of such
Options and SARs, and (iv) provide that all or any outstanding Awards shall
become exercisable or realizable in full prior to the effective date of such
Acquisition.
 
                                      B-7

  (g) Withholding. The Participant shall pay to the Company, or make provision
satisfactory to the Board for payment of, any taxes required by law to be
withheld in respect of Awards under the Plan no later than the date of the
event creating the tax liability. In the Board's discretion, and subject to
such conditions as the Board may establish, such tax obligations may be paid
in whole or in part in shares of Common Stock, including shares retained from
the Award creating the tax obligation, valued at their Fair Market Value. The
Company may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Participant.
 
  (h) Foreign Nationals. Awards may be made to Participants who are foreign
nationals or employed outside the United States on such terms and conditions
different from those specified in the Plan as the Board considers necessary or
advisable to achieve the purposes of the Plan or comply with applicable laws.
 
  (i) Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including substituting therefor another Award of the same
or a different type, changing the date of exercise or realization and
converting an Incentive Stock Option to a Nonstatutory Stock Option, provided
that the Participant's consent to such action shall be required unless the
Board determines that the action, taking into account any related action,
would not materially and adversely affect the Participant.
 
  (j) Cancellation and New Grant of Options. The Board of Directors shall have
the authority to effect, at any time and from time to time, with the consent
of the affected optionees, (i) the cancellation of any or all outstanding
Options under the Plan and the grant in substitution therefor of new Options
under the Plan covering the same or different numbers of shares of Common
Stock and having an option exercise price per share which may be lower or
higher than the exercise price per share of the cancelled Options or (ii) the
amendment of the terms of any and all outstanding Options under the Plan to
provide an option exercise price per share which is higher or lower than the
then current exercise price per share of such outstanding Options.
 
  (k) Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Stock pursuant to the Plan or to remove restrictions
from shares previously delivered under the Plan (i) until all conditions of
the Award have been satisfied or removed, (ii) until, in the opinion of the
Company's counsel, all applicable federal and state laws and regulations have
been complied with, (iii) if the outstanding Stock is at the time listed on
any stock exchange, until the shares to be delivered have been listed or
authorized to be listed on such exchange upon official notice of notice of
issuance, and (iv) until all other legal matters in connection with the
issuance and delivery of such shares have been approved by the Company's
counsel. If the sale of Stock has not been registered under the Securities Act
of 1933, as amended, the Company may require, as a condition to exercise of
the Award, such representations or agreements as the Company may consider
appropriate to avoid violation of such Act and may require that the
certificates evidencing such Stock bear an appropriate legend restricting
transfer.
 
Section 11. Miscellaneous
 
  (a) No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or service
for the Company. The Company expressly reserves the right at any time to
dismiss a Participant free from any liability or claim under the Plan, except
as expressly provided in the applicable Award.
 
  (b) No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed under
the Plan until he or she becomes the record holder thereof.
 
                                      B-8
<PAGE>
 
  (c) Exclusion from Benefit Computations. No amounts payable upon exercise of
Awards granted under the Plan shall be considered salary, wages or
compensation to Participants for purposes of determining the amount or nature
of benefits that Participants are entitled to under any insurance, retirement
or other benefit plans or programs of the Company.
 
  (d) Effective Date and Term. Subject to the approval of the stockholders of
the Company, the Plan shall be effective on June 23, 1992. Prior to such
approval, Awards may be made under the Plan expressly subject to such
approval. No Award may be made under the Plan after June 23, 2002, but Awards
previously granted may extend beyond that date.
 
  (e) Amendment of Plan. The Board may amend, suspend or terminate the Plan or
any portion thereof at any time, provided that no amendment shall be made
without stockholder approval if such approval is necessary to comply with any
applicable tax or regulatory requirement, including any requirements for
compliance with Rule 16b-3. Prior to any such approval, Awards may be made
under the Plan expressly subject to such approval.
 
  (f) Governing Law. The provisions of the Plan shall be governed by and
interpreted in accordance with the laws of the Commonwealth of Massachusetts.

Systems Incorporated is hereby amended, subject to stockholder approval, to
increase from 1,000,000 to 1,850,000 the number of shares of Common Stock
authorized for issuance under the Plan.
 
  Subsection 6(a)(i) of the Plan is hereby amended and restated in its
entirety, subject to stockholder approval, to provide as follows:
 
    (i) Subject to the provisions of the Plan, the Board may award Incentive
  Stock Options and Nonstatutory Stock Options, and determine the number of
  shares to be covered by each Option, the option price therefor and the
  conditions and limitations applicable to the exercise of the Option. The
  terms and conditions of Incentive Stock Options shall be subject to and
  comply with Section 422 of the Code, or any successor provisions, and any
  regulations thereunder. Subject to adjustment as provided in Subsection
  5(b) above, the maximum number of shares with respect to which Options may
  be granted to any employee under the Plan shall not exceed 300,000 shares
  of Common Stock during any two consecutive calendar year period. For
  purposes of calculating such maximum number, (a) an Option shall continue
  to be treated as outstanding notwithstanding its repricing, cancellation or
  expiration and (b) the repricing of an outstanding Option or the issuance
  of a new Option in substitution for a cancelled Option shall be deemed to
  constitute the grant of a new additional Option separate from the original
  grant of the Option that is repriced or cancelled.

                                                                     APPENDIX C
 
                          BANYAN SYSTEMS INCORPORATED
 
                       1995 EMPLOYEE STOCK PURCHASE PLAN
 
  The purpose of this Plan is to provide eligible employees of Banyan Systems
Incorporated (the "Company") and certain of its subsidiaries with
opportunities to purchase shares of the Company's common stock, $.01 par value
(the "Common Stock"), commencing on August 1, 1995. Four hundred and fifty
thousand (450,000) shares of Common Stock in the aggregate have been approved
for this purpose.
 
  1. Administration. The Plan will be administered by the Company's Board of
Directors (the "Board") or by a Committee appointed by the Board (the
"Committee"). The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.
 
  2. Eligibility. Participation in the Plan will neither be permitted nor
denied contrary to the requirements of Section 423 of the Internal Revenue
Code of 1986, as amended (the "Code"), and regulations promulgated thereunder.
All employees of the Company, including Directors who are employees, and all
employees of any subsidiary of the Company (as defined in Section 424(f) of
the Code) designated by the Board or the Committee from time to time (a
"Designated Subsidiary"), are eligible to participate in any one or more of
the offerings of Options (as defined in Section 9) to purchase Common Stock
under the Plan provided that:
 
    (a) they are regularly employed by the Company or a Designated Subsidiary
  for more than 20 hours a week and for more than five months in a calendar
  year; and
 
    (b) they are employees of the Company or a Designated Subsidiary on the
  first day of the applicable Plan Period (as defined below).
 
  No employee may be granted an option hereunder if such employee, immediately
after the option is granted, owns 5% or more of the total combined voting
power or value of the stock of the Company or any subsidiary. For purposes of
the preceding sentence, the attribution rules of Section 424(d) of the Code
shall apply in determining the stock ownership of an employee, and all stock
which the employee has a contractual right to purchase shall be treated as
stock owned by the employee.
 
  3. Offerings.
 
  (a) The Company will make one or more offerings ("Offerings") to employees
to purchase stock under this Plan. The first Offering under this Plan will
begin on August 1, 1995 and terminate on July 31, 1996, and subsequent
Offerings will begin on each August 1 and February 1, or the first business
day thereafter (the "Offering Commencement Dates"), the first such subsequent
Offering Commencement Date being August 1, 1996. Each Offering Commencement
Date will begin a six month period (a "Plan Period") during which payroll
deductions will be made and held for the purchase of Common Stock at the end
of the Plan Period (provided, however, that the first Offering Commencement
Date will begin a twelve month Plan Period). The Board or the Committee may,
at its discretion, choose a different Plan Period of twelve (12) months or
less for subsequent Offerings.
 
  (b) The maximum number of shares of Common Stock that shall be made
available for sale under the Plan during any Offering under the Plan shall be
225,000 shares, subject to adjustment upon changes in the capitalization of
the Company as provided in Section 15 below. If the total number of shares for
which Options are exercised on any Exercise Date in accordance with Section 9
below exceeds 225,000, the Company shall
 
                                      C-1
<PAGE>
 
make a pro rata allocation of the shares available for delivery and
distribution, and the balance of payroll deductions credited to the account of
each participant under the Plan shall be returned to the participant. If less
than 225,000 shares are purchased during an Offering, the amount not purchased
may be carried over to and made available during any subsequent Offering.
 
  4. Participation. An employee eligible on the Offering Commencement Date of
any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the employee's appropriate payroll
office at least seven (7) days prior to the applicable Offering Commencement
Date. The form will authorize a regular payroll deduction from the
Compensation received by the employee during the Plan Period. Unless an
employee files a new form or withdraws from the Plan, his deductions and
purchases will continue at the same rate for future Offerings under the Plan
as long as the Plan remains in effect. The term "Compensation" means the
amount of money reportable on the employee's Federal Income Tax Withholding
Statement, excluding overtime, shift premium, incentive or bonus awards,
allowances and reimbursements for expenses such as relocation allowances for
travel expenses, income or gains on the exercise of Company stock options or
stock appreciation rights, and similar items, whether or not shown on the
employee's Federal Income Tax Withholding Statement, but including, in the
case of salespersons, sales commissions to the extent determined by the Board
or the Committee.
 
  5. Deductions. The Company will maintain payroll deduction accounts for all
participating employees. With respect to any Offering made under this Plan, an
employee may authorize a payroll deduction in any dollar amount up to a
maximum of 10% of the Compensation he or she receives during the Plan Period
or such shorter period during which deductions from payroll are made. Payroll
deductions may be at the rate of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10% of
Compensation with any change in compensation during the Plan Period to result
in an automatic corresponding change in the dollar amount withheld.
 
  No employee may be granted an Option (as defined in Section 9) which permits
his rights to purchase Common Stock under this Plan and any other stock
purchase plan of the Company and its subsidiaries, to accrue at a rate which
exceeds $25,000 of the fair market value of such Common Stock (determined at
the Offering Commencement Date of the Plan Period) for each calendar year in
which the Option is outstanding at any time.
 
  6. Deduction Changes. An employee may decrease or discontinue his payroll
deduction once during any Plan Period, by filing a new payroll deduction
authorization form. However, an employee may not increase his payroll
deduction during a Plan Period. If an employee elects to discontinue his
payroll deductions during a Plan Period, but does not elect to withdraw his
funds pursuant to Section 8 hereof, funds deducted prior to his election to
discontinue will be applied to the purchase of Common Stock on the Exercise
Date (as defined below).
 
  7. Interest. Interest will not be paid on any employee accounts, except to
the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.
 
  8. Withdrawal of Funds. An employee may at any time prior to the close of
business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering. Partial withdrawals are
not permitted. The employee may not begin participation again during the
remainder of the Plan Period. The employee may participate in any subsequent
Offering in accordance with terms and conditions established by the Board or
the Committee, except that employees who are also directors or officers of the
Company within the meaning of Section 16 of the Securities Exchange Act of
1934 (the "Exchange Act") and the rules promulgated there under may not
participate again for a period of at least six months as provided in Rule 16b-
3(d)(2)(i) or any successor provision.
 
                                      C-2
<PAGE>
 
  9. Purchase of Shares. On the Offering Commencement Date of each Plan
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, such number of whole shares of Common Stock of the Company
reserved for the purposes of the Plan as does not exceed the number of shares
determined by dividing 6% of such employee's annualized Compensation for the
immediately prior six-month period by the price determined in accordance with
the formula set forth in the following paragraph but using the closing price
on the Offering Commencement Date of such Plan Period.
 
  The purchase price for each share purchased will be 85% of the closing price
of the Common Stock on (i) the first business day of such Plan Period or (ii)
the Exercise Date, whichever closing price shall be less. Such closing price
shall be (a) the closing price on any national securities exchange on which
the Common Stock is listed, (b) the closing price of the Common Stock on the
Nasdaq National Market or (c) the average of the closing bid and asked prices
in the over-the-counter-market, whichever is applicable, as published in The
Wall Street Journal. If no sales of Common Stock were made on such a day, the
price of the Common Stock for purposes of clauses (a) and (b) above shall be
the reported price for the next preceding day on which sales were made.
 
  Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his
accumulated payroll deductions on such date will pay for pursuant to the
formula set forth above (but not in excess of the maximum number determined in
the manner set forth above).
 
  Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period will be automatically refunded to the employee, except that
any balance which is less than the purchase price of one share of Common Stock
will be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.
 
  10. Issuance of Certificates. Certificates representing shares of Common
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the
street name of a brokerage firm, bank or other nominee holder designated by
the employee.
 
  11. Rights on Retirement, Death or Termination of Employment. In the event
of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any
pay due and owing to an employee and the balance in the employee's account
shall be paid to the employee or, in the event of the employee's death, (a) to
a beneficiary previously designated in a revocable notice signed by the
employee (with any spousal consent required under state law) or (b) in the
absence of such a designated beneficiary, to the executor or administrator of
the employee's estate or (c) if no such executor or administrator has been
appointed to the knowledge of the Company, to such other person(s) as the
Company may, in its discretion, designate. If, prior to the last business day
of the Plan Period, the Designated Subsidiary by which an employee is employed
shall cease to be a subsidiary of the Company, or if the employee is
transferred to a subsidiary of the Company that is not a Designated
Subsidiary, the employee shall be deemed to have terminated employment for the
purposes of this Plan.
 
  12. Optionees Not Stockholders. Neither the granting of an Option to an
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.
 
                                      C-3
<PAGE>
 
  13. Rights Not Transferable. Rights under this Plan are not transferable by
a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.
 
  14. Application of Funds. All funds received or held by the Company under
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.
 
  15. Adjustment in Case of Changes Affecting Common Stock. In the event of a
subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately,
and such other adjustment shall be made as may be deemed equitable by the
Board or the Committee. In the event of any other change affecting the Common
Stock, such adjustment shall be made as may be deemed equitable by the Board
or the Committee to give proper effect to such event.
 
  16. Merger. If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least
80% by voting power of the capital stock of the surviving corporation
("Continuity of Control"), the holder of each Option then outstanding will
thereafter be entitled to receive at the next Exercise Date upon the exercise
of such Option for each share as to which such Option shall be exercised the
securities or property which a holder of one share of the Common Stock was
entitled to upon and at the time of such merger, and the Committee shall take
such steps in connection with such merger as the Committee shall deem
necessary to assure that the provisions of Paragraph 15 shall thereafter be
applicable, as nearly as reasonably may be, in relation to the said securities
or property as to which such holder of such Option might thereafter be
entitled to receive thereunder.
 
  In the event of a merger or consolidation of the Company with or into
another corporation which does not involve Continuity of Control, or of a sale
of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, (a) subject to the provisions of
clauses (b) and (c), after the effective date of such transaction, each holder
of an outstanding Option shall be entitled, upon exercise of such Option, to
receive in lieu of shares of Common Stock, shares of such stock or other
securities as the holders of shares of Common Stock received pursuant to the
terms of such transaction; or (b) all outstanding Options may be cancelled by
the Board or the Committee as of a date prior to the effective date of any
such transaction and all payroll deductions shall be paid out to the
participating employees; or (c) all outstanding Options may be cancelled by
the Board or the Committee as of the effective date of any such transaction,
provided that notice of such cancellation shall be given to each holder of an
Option, and each holder of an Option shall have the right to exercise such
Option in full based on payroll deductions then credited to his account as of
a date determined by the Board or the Committee, which date shall not be less
than ten (10) days preceding the effective date of such transaction.
 
  17. Amendment of the Plan. The Board may at any time, and from time to time,
amend this Plan in any respect, except that (a) if the approval of any such
amendment by the shareholders of the Company is required by Section 423 of the
Code or by Rule 16b-3 under the Exchange Act, such amendment shall not be
effected without such approval, and (b) in no event may any amendment be made
which would cause the Plan to fail to comply with Section 16 of the Exchange
Act and the rules promulgated thereunder, as in effect from time to time, or
Section 423 of the Code.
 
  18. Insufficient Shares. In the event that the total number of shares of
Common Stock specified in elections to be purchased under any Offering plus
the number of shares purchased under previous Offerings under this
 
                                      C-4
<PAGE>
 
Plan exceeds the maximum number of shares issuable under this Plan, the Board
or the Committee will allot the shares then available on a pro rata basis.
 
  19. Termination of the Plan. This Plan may be terminated at any time by the
Board. Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.
 
  20. Governmental Regulations. The Company's obligation to sell and deliver
Common Stock under this Plan is subject to listing on a national stock
exchange or quotation on the Nasdaq National Market and the approval of all
governmental authorities required in connection with the authorization,
issuance or sale of such stock.
 
  The Plan shall be governed by Massachusetts law except to the extent that
such law is preempted by federal law.
 
  The Plan is intended to comply with the provisions of Rule 16b-3 promulgated
under the Securities Exchange Act of 1934. Any provision inconsistent with
such Rule shall to that extent be inoperative and shall not affect the
validity of the Plan.
 
  21. Issuance of Shares. Shares may be issued upon exercise of an Option from
authorized but unissued Common Stock, from shares held in the treasury of the
Company, or from any other proper source.
 
  22. Notification upon Sale of Shares. Each employee agrees, by entering the
Plan, to promptly give the Company notice of any disposition of shares
purchased under the Plan where such disposition occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased.
 
  23. Effective Date and Approval of Shareholders. The Plan shall take effect
on July 21, 1995 subject to approval by the shareholders of the Company as
required by Rule 16b-3 under the Exchange Act and by Section 423 of the Code,
