                                PROXY STATEMENT
                                 MARCH 21, 2001

     Proxies in the form enclosed with this proxy statement are solicited by the
Board of Directors of Concord Communications, Inc. (the "Corporation") for use
at the Annual Meeting of Stockholders (the "Annual Meeting") to be held on April
25, 2001, at 8:00 A.M., at the offices of the Corporation, 600 Nickerson Road,
Marlboro, Massachusetts.

     Only stockholders of record as of the close of business on February 26,
2001, (the "Record Date") will be entitled to vote at the Annual Meeting and any
adjournments thereof. As of the Record Date, 16,558,756 shares (excluding
treasury shares) of Common Stock of the Corporation were issued and outstanding.
Each share outstanding as of the Record Date will be entitled to one vote, and
stockholders may vote in person or by proxy. Execution of a proxy will not in
any way affect a stockholder's right to attend the Annual Meeting and vote in
person. Any stockholder delivering a proxy has the right to revoke it only by
written notice to the Clerk delivered at any time before it is exercised,
including at the Annual Meeting.

     The persons named as attorneys-in-fact in the proxies are officers of the
Corporation. All properly executed proxies returned in time to be cast at the
Annual Meeting will be voted. With respect to the election of Directors, any
stockholder submitting a proxy has a right to withhold authority to vote for any
individual nominee by writing that nominee's name in the space provided on the
proxy. The proxies will be voted as stated below under "Election of Directors."
In addition to the election of Directors, the stockholders will consider and
vote upon a proposal to ratify the selection of auditors. Where a choice has
been specified on the proxy with respect to the foregoing matters, the shares
represented by the proxy will be voted in accordance with the specification and
will be voted FOR if no specification is indicated.

     A majority in interest of the outstanding shares represented at the meeting
in person or by proxy shall constitute a quorum for the transaction of business.
Votes withheld from any nominee, abstentions and broker "non-votes" are counted
as present or represented for purposes of determining the presence or absence of
a quorum for the meeting. A "non-vote" occurs when a nominee holding shares for
a beneficial owner votes on one proposal, but does not vote on another proposal
because the nominee does not have discretionary voting power and has not
received instructions from the beneficial owner. Directors are elected by a
plurality of the votes cast by stockholders entitled to vote at the meeting. On
all other matters being submitted to stockholders, an affirmative vote of at
least a majority of the shares present, or represented, and entitled to vote at
the meeting is required for approval. An automated system administered by the
Corporation's transfer agent tabulates the votes. The vote on each matter
submitted to stockholders is tabulated separately. Abstentions are included in
the number of shares present or represented and voting on each separate matter.
Broker "non-votes" are not so included.

     The Board of Directors knows of no other matter to be presented at the
Annual Meeting. If any other matter should be presented at the Annual Meeting
upon which a vote properly may be taken, shares represented by all proxies
received by the Board of Directors will be voted with respect thereto in
accordance with the judgment of the persons named as attorneys-in-fact in the
proxies.

     This proxy statement and the accompanying proxy were first mailed to
stockholders on or about March 23, 2001. A copy of an Annual Report to
Stockholders, containing financial statements for the fiscal year ended December
31, 2000, also accompanied the proxy statement and proxy. The Corporation will
   4

provide, without charge, to each person solicited by this proxy statement, a
copy of the Corporation's Annual Report on Form 10-K for the fiscal year ended
December 31, 2000, upon such person's written request to Melissa H. Cruz,
Executive Vice President, Business Services and Chief Financial Officer, Concord
Communications, Inc., 600 Nickerson Road, Marlboro, Massachusetts 01752.

                                     ITEM 1

                             ELECTION OF DIRECTORS

     The Corporation's Board of Directors is divided into three classes. Each
class serves three years, with the terms of office of the respective classes
expiring in successive years. The present term of office for the Class I
Directors expires at the Annual Meeting. John Robert Held and Robert C. Hawk,
who both have served as Class I Directors since 1996, have declined to be
renominated to another term as Class I Directors and each will resign as Class I
Directors effective immediately prior to this Annual Meeting. Mr. Held's and Mr.
Hawk's decisions not to be renominated are not related to any disagreement with
the Corporation or Board of Directors with respect to the Corporation's
operations, policies or practices. In connection with the foregoing, the
Corporation's Board of Directors has reclassified the Board of Directors
effective immediately prior to the Annual Meeting of Stockholders and nominated
for re-election as Class I Directors Messrs. Kamra and Wadsworth, each of whom
first became Directors of the Corporation in 1993. If re-elected, the Class I
nominees will hold office until the Annual Meeting of Stockholders to be held in
2004, and until their successors shall have been elected and shall have been
qualified. Shares represented by all proxies received by the Board of Directors
and not so marked as to withhold authority to vote for any individual nominee
will be voted (unless one or more nominees are unable or unwilling to serve) for
the election of the Class I nominees. The Board of Directors knows of no reason
why any such nominee should be unable or unwilling to serve, but if such should
be the case, proxies will be voted for the election of some other person or the
Board of Directors will fix the number of Directors at a lesser number.

     The following table sets forth the nominees to be elected at the Annual
Meeting and the other current Directors, the year each nominee or Director was
first appointed or elected a Director, the principal occupation of each of the
nominees and Directors during the past five years, and the ages of each of the
nominees and Directors.



                                                    PRINCIPAL OCCUPATION AND           YEAR CURRENT

DIRECTOR COMPENSATION

     Directors who are not employees of the Corporation (also referred to as
"outside Directors"), who currently consist of Messrs. Bolander, Burnes, Hawk,
Held, Kamra and Wadsworth, do not receive an annual retainer or any fees for
attending regular meetings of the Board of Directors. Directors are reimbursed
for reasonable out-of-pocket expenses incurred in attending such meetings.
Outside Directors are also eligible for participation in the Corporation's 1997
Non-Employee Director Stock Option Plan.
                                        3
   6

     Prior to the Corporation's initial public offering, the Corporation granted
non-qualified stock options to Directors under its 1995 Stock Plan (the "1995
Plan"). Pursuant to the terms of the 1995 Plan, options granted under the 1995
Plan are exercisable within eight years of the original grant date and generally
vest over a period of four years from the date of grant. As of March 1, 2001,
options to purchase 62,500 shares of Common Stock, at a weighted average
exercise price of $1.90 per share, had been granted to outside Directors of the
Corporation under the 1995 Plan. Of that number, options to purchase 59,687
shares of Common Stock have been exercised and no options to purchase shares of
Common Stock have been canceled. Upon the consummation of a "change in control"
of the Corporation, each stock option agreement governing options granted under
the 1995 Plan provides for the acceleration of vesting of the option by eighteen
months. The Corporation's ability to make additional grants or awards under the
1995 Plan was terminated upon the completion of the Corporation's initial public
offering in October 1997; however, the 1995 Plan continues to govern all
options, awards and other grants granted and outstanding under the 1995 Plan.

     The 1997 Non-Employee Director Stock Option Plan (the "Non-Employee
Director Plan"), providing for the annual grant of stock options to purchase
shares of Common Stock to outside Directors, was adopted by the Board of
Directors in July 1997 and approved by the stockholders on September 9, 1997. A
total of 130,000 shares of Common Stock are reserved for issuance under the
Non-Employee Director Plan, as amended. The Non-Employee Director Plan is
administered by the Compensation Committee of the Board of Directors. Under the
Non-Employee Director Plan each new eligible Director will be granted an option
to purchase 20,000 shares of Common Stock upon the Director's first appointment
or election to the Board of Directors and each eligible Director will be
automatically granted an option to purchase 5,000 shares of Common Stock each
year following the final adjournment of the Corporation's Annual Meeting of
Stockholders.

     The exercise price of options granted under the Non-Employee Director Plan
will be 100% of the fair market value per share of the Common Stock on the date
the option is granted. Options initially granted to each Director under the
Non-Employee Director Plan will become exercisable over a four-year period from
the date of grant. Under their respective stock option agreements, each
director's options will expire on the eighth anniversary of the grant date. If
an optionee ceases to be a director of the Corporation each option will
terminate with respect to the shares as to which the option is not then
exercisable and any portion of his or her option which is vested but has not
been exercised may be exercised within sixty days of the date such director
ceased to be a director. In the event of a merger, consolidation or similar
corporate transaction, the vesting of all outstanding options under the
Non-Employee Director Plan will be accelerated so that all outstanding options
are vested and exercisable in full prior to the consummation of such
transaction. If such options are not exercised prior to the consummation of such
transaction, and are not assumed or replaced by the successor entity, such
options will terminate.

     As of December 31, 2000, 32,500 options to purchase shares of the
Corporation's Common Stock were outstanding under the Non-Employee Director
Plan.

(1) Stock options were granted under the Corporation's 1997 Stock Plan at an
    exercise price equal to the fair market value of the Corporation's Common
    Stock on the date of grant. Under their respective stock option agreements,
    each executive officer's options will expire on the eighth anniversary from
    the date of

                                        8
   11

    grant. The options generally become exercisable as follows: 25% on the first
    anniversary of the date of grant and quarterly for the remaining three
    years.

(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming the specified compounded rates of appreciation (5% and 10%) of
    the Corporation's Common Stock over the term of the options. These numbers
    are calculated based on rules promulgated by the Securities and Exchange
    Commission and do not reflect the Corporation's estimate of future stock
    price increases. Actual gains, if any, on stock option exercises and Common
    Stock holdings are dependent on the timing of such exercise and the future
    performance of the Corporation's Common Stock. There can be no assurance
    that the rates of appreciation assumed in this table can be achieved or that
    the amounts reflected will be received by the individuals.

     The following table provides information on stock option exercises in 2000
by the named executive officers and the value of such officers' unexercised
options at December 31, 2000.

                         COMPENSATION COMMITTEE REPORT

PURPOSE OF THE COMPENSATION COMMITTEE

     The Compensation Committee of the Corporation's Board of Directors (the
"Committee") has the exclusive authority to establish the level of base salary
payable to the Chief Executive Officer and other executive officers of the
Corporation and to administer the Corporation's stock option plans, including
the 1997 Stock Plan and the 1997 Non-Employee Director Stock Option Plan. In
addition, the Committee has the responsibility for approving the individual
variable compensation cash bonus programs to be in effect for the Chief
Executive Officer and other executive officers. The Committee is comprised
entirely of outside directors who have never served as officers of the
Corporation.

                                        9
   12

GENERAL COMPENSATION POLICY

     The Committee believes that the compensation programs for executive
officers of the Corporation should be designed to attract, motivate, and retain
talented executives responsible for the success of the Corporation and should be
determined within a competitive framework and based on the achievement of
overall financial results and individual contributions. The Committee's
objectives are to:

          (1) Offer a total compensation program that is highly competitive with
     comparable talent at comparable high-growth software companies.

          (2) Provide annual variable incentive awards in the form of cash
     bonuses that take into account the Corporation's overall financial
     performance relative to corporate objectives.

          (3) Align the financial interests of executive officers with those of
     the stockholders by providing significant equity-based, long-term incentive
     awards.

COMPENSATION COMPONENTS AND PROCESS

  BASE SALARY

     The base salary for each executive officer is set on the basis of the
responsibilities of the position held, the experience and performance of the
individual, and a review of comparable positions based on surveys of the
industry.

  VARIABLE INCENTIVE AWARDS -- CASH BONUSES

     The Corporation's Bonus Plan is designed to reward executive officers for
the achievement by the Corporation of its performance objectives. The cash bonus
to be paid to each executive officer is calculated as a percentage of his or her
base salary. A specific formula, based on the revenues and net income of the
Corporation, is in place to calculate the actual incentive payment for each
officer. A compensation target is set for each executive officer based on
compensation targets of comparable positions. In 2000, the Corporation did not
meet its performance targets, and bonuses paid reflected these results.

  LONG TERM STOCK-BASED INCENTIVE AWARDS

     During 2000, the Committee made option grants under the 1997 Stock Plan to
Messrs. Blaeser, Cruz, Conklin, Phillips, Engel and Hamilton. Each grant allows
the officer to acquire shares of the Corporation's Common Stock at a fixed price
per share (the market price on the grant date) over a specified period of time.
Each option vests in periodic installments over a four-year period, as specified
in the option agreements applicable to each executive.

     Generally, stock options are granted when an executive joins the
Corporation. Additional options are granted on the basis of the individual's
performance, potential for future responsibility and the number of unvested
options held by the individual at the time of the new grant. The grants are
designed to align the interests of executive officers with stockholders and to
provide each executive officer with a significant incentive to manage the
Corporation effectively.

     In August 1999, the Compensation Committee became aware that the options
that the Corporation had awarded in January 1999 had exercise prices that were
significantly above the August market price. The

                                        10
   13

Committee was concerned that the option awards would not have their intended
effect of retaining and motivating key employees and executive officers in their
performance for the Corporation, particularly since the Corporation is faced
with a fiercely competitive market for the services of key personnel. The
Committee decided that rather than wait until January 2000, the Corporation's
usual time for executive officer and key employee retention and incentive option
awards, the Corporation would benefit from making an immediate grant of stock
option awards. Accordingly, in lieu of a January 2000 grant, the Corporation
awarded stock options to key employees and executive officers in August 1999.

     In April 2000, the Compensation Committee granted additional stock options
to existing executive officers in order to retain and motivate these executive
officers. In November 2000, the Compensation Committee became aware that the
options the Corporation awarded to certain executive officers and key employees
in both April 2000 and August 1999 had exercise prices that were significantly
above the November market prices. The Committee was concerned that the option
awards would not have their intended effect of retaining and motivating key
employees and executive officers in their performance for the Corporation,
particularly since the Corporation is faced with a fiercely competitive market
for the services of key personnel. The Committee decided that rather than wait
until January 2001, the Corporation's usual time for executive officer and key
employee retention and incentive option awards, the Corporation would benefit
from making an immediate grant of stock option awards. Accordingly, in lieu of a
January 2001 grant, the Corporation awarded stock options to key employees and
executive officers in November 2000.

CHIEF EXECUTIVE OFFICER COMPENSATION

     The annual base salary for the Corporation's Chief Executive Officer is
determined by the Committee, subject to approval of the Board of Directors. The
2000 compensation package of the Corporation's President and Chief Executive
Officer, Mr. Blaeser, consisted of the same benefits program as other executive
officers, including base salary, cash bonus, stock options and other employee
benefit programs. Specifically, a target incentive was established at the
beginning of the year using an agreed-upon formula based on the Corporation's
performance. In 2000, the Corporation did not meet its performance targets and
Mr. Blaeser's compensation reflects this result, including a decrease in cash
bonus from 1999. Each year, the annual incentive plan is reevaluated with new
targets for revenue growth and profitability. The option grants made to Mr.
Blaeser during the 2000 fiscal year were based upon his individual performance
and leadership within the Corporation and were designed to place a significant
portion of his total compensation at risk, because the options will have no
value unless there is appreciation in the value of the Corporation's Common
Stock over the option term.

COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(m)

     In general, under Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code"), the Corporation cannot deduct, for federal income tax
purposes, compensation in excess of $1,000,000 paid to certain executive
officers. This deduction limitation does not apply, however, to compensation
that constitutes "qualified performance-based compensation" within the meaning
of Section 162(m) of the Code and the regulations promulgated thereunder. The
Corporation has considered the limitations on deductions imposed by Section
162(m) of the Code, and it is the Corporation's present intention that, for so
long as it is consistent with its overall compensation objective, substantially
all tax deductions attributable to executive compensation will not be subject to
the deduction limitations of Section 162(m) of the Code.

                                        11
   14

OTHER ELEMENTS OF EXECUTIVE COMPENSATION

     Executives are eligible for Corporation-wide medical and dental benefits
and participation in a 401(k) plan under which the Corporation provided no
matching contributions in 2000. In addition, executives participate in a
Corporation-wide long-term disability insurance program and a group term life
insurance program.

COMPENSATION COMMITTEE INTERLOCK AND INSIDER PARTICIPATION

     Messrs. Bolander, Burnes, Held and Wadsworth comprised the Compensation
Committee for fiscal year 2000. No member of the Committee was at any time
during the past year an officer or employee of the Corporation or any of its
subsidiaries, was formerly an officer of the Corporation or any of its
subsidiaries, or had any relationship with the Corporation requiring disclosure
herein.

     During 2000, no executive officer of the Corporation served as a member of
the compensation committee (or other Board committee performing equivalent
functions, or in the absence of any such committee, the entire Board) of another
entity, one of whose executive officers served as a member of the Corporation's
Compensation Committee or as a director of the Corporation. In addition, during
the last year, no executive officer of the Corporation served on the Board of
another entity, one of whose executive officers served as a member of the
Corporation's Compensation Committee.

EMPLOYMENT AGREEMENTS

     As of December 31, 2000, the Corporation has entered into a Management
Change in Control Agreement (the "Management Agreements") with each of John A.
Blaeser, Kevin J. Conklin, Ferdinand Engel and Melissa H. Cruz. Pursuant to the
terms of the Management Agreements, each of the foregoing executive officers
(other than Mr. Blaeser) is entitled to receive a single severance payment in
cash in an amount equal to six months' base annual salary (and equal to twelve
months' base annual salary in the case of Mr. Blaeser) if any such executive
officer is terminated by the Corporation without cause or such executive officer
voluntarily terminates his employment with the Corporation for "good reason"
(each a "Termination Event"), in each case within six months of a change in
control of the Corporation. In addition, effective upon a change in control of
the Corporation, the vesting date for each such executive officer's unvested
options shall be accelerated by a period of 24 months. If within 24 months of a
change in control of the Corporation there is a Termination Event, all of such
executive officer's remaining unvested options will become fully vested. Each
such executive officer has entered into a non-competition agreement with the
Corporation pursuant to which each such executive officer has agreed following a
change in control of the Corporation not to compete with the Corporation for a
period of six months if such executive officer has been terminated with or
without cause by the Corporation or has voluntarily terminated his employment
for "good reason."

     In addition, certain of John A. Blaeser's option agreements provide for
automatic acceleration of all of his unvested options following a merger,
consolidation, or a sale, conveyance or disposition of all or substantially all
of the assets of the Corporation or if he is no longer a director of the
Corporation, other than by reason of death, disability, or resignation.

                             AUDIT COMMITTEE REPORT

     The Board of Directors of the Corporation has appointed an Audit Committee
to assist the Board of Directors with its oversight responsibilities, including,
among other things:

     - Reviewing and maintaining the adequacy of the Corporation's internal
       controls and financial reporting processes and the overall reliability of
       the Corporation's financial reports to the public;

     - Ascertaining the independence and overseeing the performance of the
       Corporation's external independent auditors; and

     - Providing guidance on the Corporation's compliance with legal and
       regulatory requirements related to its financial reporting.

     The Audit Committee is currently comprised of three members of the Board of
Directors, Messrs. Burnes, Kamra and Held, each of whom, as interpreted by the
Board of Directors in its business judgment, (a) has met the independence
requirements of the Nasdaq (i.e., the Board of Directors has determined that
none of the committee members has a relationship to the Corporation that may
interfere with his independence from the Corporation and its management) and (b)
is financially literate.

     The Audit Committee regularly discusses with management and the outside
auditors the financial information developed by the Corporation, the
Corporation's systems of internal controls and its audit process. The Audit
Committee recommends to the Board each fiscal year the appointment of the
independent auditors and reviews periodically the auditors' performance and
independence from management. The Audit Committee met with the independent
auditors (both with and without the presence of the Corporation's management) to
review and discuss the matters required to be discussed by Statement of
Accounting Standards 61 (Codification of Statements on Auditing Standards),
including various matters pertaining to the audit, including the Corporation's
financial statements, the report of the independent auditors on the results,
scope and terms of their work, and their recommendations concerning the
financial practices, controls, procedures and policies employed by the
Corporation.

     The Board of Directors has adopted a written charter for the Audit
Committee setting out the audit related functions the committee is to perform. A
copy of the charter is attached to this proxy statement as Appendix A. This
year, the Audit Committee reviewed the Corporation's audited financial
statements and met with both management and Arthur Andersen LLP, the
Corporation's independent auditors, to discuss those financial statements.
Management has represented to the Audit Committee that the financial statements
were prepared in accordance with generally accepted accounting principles. The
Audit Committee has received from and discussed with Arthur Andersen LLP the
written disclosure and the letter required by Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees).

     Based on these reviews and discussions, the Audit Committee recommended to
the Board of Directors that the Corporation's audited financial statements be
included in its Annual Report on Form 10-K for the fiscal year ended December
31, 2000.

  Audit Fees

     The aggregate fees billed by Arthur Andersen for professional services
rendered for the audit of the Corporation's annual financial statements for the
fiscal year ended December 31, 2000 and for the review of the financial
statements included in the Corporation's Forms 10-Q for the fiscal year ended
December 31, 2000 were $75,000.

  Financial Information Systems Design and Implementation Fees

     The aggregate fees billed by Arthur Andersen LLP for financial information
systems design and implementation professional services for the fiscal year
ended December 31, 2000 were $0.

  All Other Fees

     The aggregate fees billed by Arthur Andersen LLP and KPMG, LLP (former
auditor First Sense Software, Inc.) for services other than those described
above including, without limitation, pooling reports, pooling restatements, tax
returns and tax consulting, for the fiscal year ended December 31, 2000 were
$353,200. The Audit Committee determined that the services provided by Arthur
Andersen LLP described immediately above were compatible with its independence.

     The Corporation's Audit Committee has determined that the provision of the
services provided by Arthur Andersen as set forth herein are compatible with
maintaining Arthur Andersen' independence.

                                     ITEM 2

                     RATIFICATION OF SELECTION OF AUDITORS

     The Board of Directors has selected the firm of Arthur Andersen LLP,
independent certified public accountants, to serve as auditors for the fiscal
year ending December 31, 2001. Arthur Andersen LLP has served as the
Corporation's auditors since 1986. It is expected that a member of the firm will
be present at the Annual Meeting of Stockholders with the opportunity to make a
statement if so desired and will be available to respond to appropriate
questions. If the stockholders do not ratify the selection of Arthur Andersen
LLP as the Company's independent public accountants for the fiscal year ended
December 31, 2001, the Company's Board of Directors will evaluate what would be
in the best interests of the Company and its stockholders and consider whether
to select new independent public accountants for the current fiscal year or
whether to wait until the completion of the audit for the current fiscal year
before changing independent public accountants.

  THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THIS SELECTION.

                             STOCKHOLDER PROPOSALS

     Proposals of stockholders intended for inclusion in the Corporation's proxy
materials to be furnished to all stockholders entitled to vote at the 2002
Annual Meeting of Stockholders pursuant to SEC Rule 14a-8 must be received at
the Company's principal executive offices not later than December 12, 2001.

     Under the Corporation's By-Laws, stockholders who wish to make a proposal
at the 2002 Annual Meeting -- other than one that will be included in the
Corporation's proxy materials -- must notify the Clerk of the Corporation no
earlier than January 25, 2002 and no later than February 24, 2002. If a
stockholder who wishes to present a proposal fails to notify the Corporation by
February 24, 2002, the stockholder would not be entitled to present the proposal
at the meeting. If, however, notwithstanding the requirements of the
Corporation's Restated By-Laws, the proposal is brought before the meeting, then
under the SEC's proxy rules the proxies solicited by management with respect to
the 2001 Annual Meeting will confer discretionary voting authority with respect
to the stockholder's proposal on the persons selected by management to vote the
proxies. If a stockholder makes a timely notification, the proxies may still
exercise discretionary voting authority under circumstances consistent with the
SEC's proxy rules. In order to minimize controversy as to the date on which a
proposal was received by the Corporation, it is suggested that proponents submit
their proposals by Certified Mail -- Return Receipt Requested.

                           EXPENSES AND SOLICITATION

     The cost of solicitation of proxies will be borne by the Corporation, and
in addition to soliciting stockholders by mail through its regular employees,
the Corporation may request banks and brokers to solicit their customers who
have stock of the Corporation registered in the names of a nominee and, if so,
will reimburse such banks and brokers for their reasonable out-of-pocket costs.
Solicitation by officers and employees of the Corporation may also be made of
some stockholders in person or by mail, telephone or telegraph following the
original solicitation. The Corporation may, if appropriate, retain an
independent proxy solicitation firm to assist in soliciting proxies. If the
Corporation does so, it will pay such firm's customary fees and expenses.

                            AUDIT COMMITTEE CHARTER

A.  PURPOSE AND SCOPE

     The primary function of the Audit Committee (the "Committee") is to assist
the Board of Directors in fulfilling its responsibilities by reviewing: (i) the
financial reports provided by the Corporation to the Securities and Exchange
Commission ("SEC"), the Corporation's shareholders or to the general public, and
(ii) the Corporation's internal financial and accounting controls.

B.  COMPOSITION

     The Committee shall be comprised of a minimum of three directors as
appointed by the Board of Directors, who shall meet the independence and audit
committee composition requirements under any rules or regulations of The NASDAQ
National Market, as in effect from time to time, and shall be free from any
relationship that, in the opinion of the Board of Directors, would interfere
with the exercise of his or her independent judgment as a member of the
Committee.

     All members of the Committee shall either (i) be able to read and
understand fundamental financial statements, including a balance sheet, cash
flow statement and income statement, or (ii) be able to do so within a
reasonable period of time after appointment to the Committee. At least one
member of the Committee shall have employment experience in finance or
accounting, requisite professional certification in accounting, or other
comparable experience or background which results in the individual's financial
sophistication, including being or having been a chief executive officer, chief
financial officer or other senior officer with financial oversight
responsibilities.

     The Board may appoint one member who does not meet the independence
requirements set forth above and who is not a current employee of the
Corporation or an immediate family member of such employee if the Board, under
exceptional and limited circumstances, determines that membership on the
Committee by the individual is required in the best interests of the Corporation
and its shareholders. The Board shall disclose in the next proxy statement after
such determination the nature of the relationship and the reasons for the
determination.

     The members of the Committee shall be elected by the Board of Directors at
the meeting of the Board of Directors following each annual meeting of
stockholders and shall serve until their successors shall be duly elected and
qualified or until their earlier resignation or removal. Unless a Chair is
elected by the full Board of Directors, the members of the Committee may
designate a Chair by majority vote of the full Committee membership.

C.  RESPONSIBILITIES AND DUTIES

     To fulfill its responsibilities and duties the Committee shall:

  Document Review

          1.  Review and assess the adequacy of this Charter periodically as
     conditions dictate, but at least annually (and update this Charter if and
     when appropriate).

                                       A-1
   21

          2.  Review with representatives of management and representatives of
     the independent accounting firm the Corporation's audited annual financial
     statements prior to their filing as part of the Annual Report on Form 10-K.
     After such review and discussion, the Committee shall recommend to the
     Board of Directors whether such audited financial statements should be
     published in the Corporation's annual report on Form 10-K. The Committee
     shall also review the Corporation's quarterly financial statements prior to
     their inclusion in the Corporation's quarterly SEC filings on Form 10-Q.

          3.  Take steps designed to insure that the independent accounting firm
     reviews the Corporation's interim financial statements prior to their
     inclusion in the Corporation's quarterly reports on Form 10-Q.

  Independent Accounting Firm

          4.  Recommend to the Board of Directors the selection of the
     independent accounting firm, and approve the fees and other compensation to
     be paid to the independent accounting firm. The Committee shall have the
     ultimate authority and responsibility to select, evaluate and, when
     warranted, replace such independent accounting firm (or to recommend such
     replacement for shareholder approval in any proxy statement).

          5.  On an annual basis, receive from the independent accounting firm a
     formal written statement identifying all relationships between the
     independent accounting firm and the Corporation consistent with
     Independence Standards Board ("ISB") Standard 1. The Committee shall
     actively engage in a dialogue with the independent accounting firm as to
     any disclosed relationships or services that may impact its independence.
     The Committee shall take, or recommend that the Board of Directors take,
     appropriate action to oversee the independence of the independent
     accounting firm.

          6.  On an annual basis, discuss with representatives of the
     independent accounting firm the matters required to be discussed by
     Statement on Auditing Standards ("SAS") 61, as it may be modified or
     supplemented.

          7.  Meet with the independent accounting firm prior to the audit to
     review the planning and staffing of the audit.

          8.  Evaluate the performance of the independent accounting firm and
     recommend to the Board of Directors any proposed discharge of the
     independent accounting firm when circumstances warrant. The independent
     accounting firm shall be ultimately accountable to the Board of Directors
     and the Committee.

  Financial Reporting Processes

          9.  In consultation with the independent accounting firm and
     management, review annually the adequacy of the Corporation's internal
     financial and accounting controls.

  Compliance

          10.  To the extent deemed necessary by the Committee, it shall have
     the authority to engage outside counsel and/or independent accounting
     consultants to review any matter under its responsibility.

  Reporting

     supplemented from time to time, a written report of the audit committee to
     be included in the Corporation's annual proxy statement for each annual
     meeting of stockholders occurring after December 14, 2000.

     While the Audit Committee has the responsibilities and powers set forth in
this Charter, it is not the duty of the Audit Committee to plan or conduct
audits or to determine that the Corporation's financial statements are complete
and accurate and are in accordance with generally accepted accounting
principles.
