of the meeting or in a duly executed waiver of notice thereof.

            2.2 ANNUAL MEETING. Annual meetings of stockholders shall be held on
such date and at such time as shall be designated from time to time by the Board
of Directors and stated in the notice of the meeting, at which the stockholders
shall elect a Board of Directors and transact such other business as may
properly be brought before the meeting.

            2.3 ANNUAL MEETING NOTICE. Written notice of the annual meeting
stating the place, date and hour of the meeting shall be given to each
stockholder entitled to vote at such meeting not less than ten, nor more than
sixty, days before the date of the meeting.

            2.4 VOTING LIST. The officer who has charge of the stock ledger of
the Corporation shall prepare and make, at least ten days before every meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present. This list shall
<PAGE>

presumptively determine the identity of the stockholders entitled to vote at the
meeting and the number of shares held by each of them.

            2.5 SPECIAL STOCKHOLDERS MEETINGS. Special meetings of stockholders
may be called at any time by the Chairman of the Board (if any), a majority of
the Board of Directors or the President and shall be held at such place, on such
date and at such time as shall be fixed by the Board of Directors or the person
calling the meeting. Business transacted at any special meeting of stockholders
shall be limited to matters relating to the purpose or purposes stated in the
notice of meeting.

            2.6 NOTICE OF SPECIAL MEETING. Written notice of a special meeting
stating the place, date and hour of the meeting and the purpose or purposes for
which the meeting is called, shall be given not less than ten, nor more than

            2.7 PURPOSES OF SPECIAL MEETINGS. Business transacted at any special
meeting of stockholders shall be limited to the purposes stated in the notice.

            2.8 QUORUM. A majority of the voting power of the Corporation,
present in person or represented by proxy, shall constitute a quorum at all
meetings of the stockholders for the transaction of business except as otherwise
provided by statute, the Certificate of Incorporation or these by-laws. Shares
held by brokers which such brokers are prohibited from voting (pursuant to their
discretionary authority on behalf of beneficial owners of such shares who have
not submitted a proxy with respect to such shares) on some or all of the matters
before the stockholders, but which shares would otherwise be entitled to vote at
the meeting ("Broker Non-Votes") shall be counted, for the purpose of
determining the presence or absence of a quorum, both (a) toward the total
voting power of the shares of capital stock of the Corporation and (b) as being
represented by proxy. If a quorum has been established for the purpose of
conducting the meeting, a quorum shall be deemed to be present for the purpose
of all votes to be conducted at such meeting, provided that where a separate
vote by a class or classes, or series thereof, is required, a majority of the
voting power of the shares of such class or classes, or series, present in
person or represented by proxy shall constitute a quorum entitled to take action
with respect to that vote on that matter. If, however, such quorum shall not be
present or represented at any meeting of the stockholders, the chairman of the
meeting or the stockholders holding a majority of the voting power of the shares
of stock entitled to vote thereat, present in person or represented by proxy,
shall have power to adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present or
represented. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting.

            2.9 CONTROLLING VOTE. When a quorum is present at any meeting, the
vote of the holders of a majority of the voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express
<PAGE>

provision of a statute, the Certificate of Incorporation or these by-laws a
different vote is required, in which case such express provision shall govern
and control the decision of such question. Any election of directors by the
stockholders shall be determined by a plurality of the votes cast by the
stockholders entitled to vote at such election, except as otherwise provided by
the Certificate of Incorporation. For the purposes of this Section 2.9, Broker
Non-Votes represented at the meeting but not permitted to vote on a particular
matter shall not be counted, with respect to the vote on such matter, in the
number of (a) votes cast, (b) votes cast affirmatively, or (c) votes cast
negatively.

            2.10 VOTING AND PROXIES. At any meeting of the stockholders, each
stockholder shall have one vote for each share of stock entitled to vote at such
meeting held of record by such stockholder and a proportionate vote for each
fractional share so held, unless otherwise provided in the Certificate of
Incorporation. Each stockholder of record entitled to vote at a meeting of
stockholders, or to express consent or dissent to corporate action in writing
without a meeting (to the extent not otherwise prohibited by the Certificate of
Incorporation or these by-laws), may vote or express such consent or dissent in
person or may authorize another person or persons to vote or act for such
stockholder by written proxy executed by such stockholder or his or her
authorized agent or by a transmission permitted by law and delivered to the
secretary of the Corporation. No such proxy shall be voted or acted upon after
three years from the date of its execution, unless the proxy expressly provides
for a longer period. Any copy, facsimile telecommunication or other reliable
reproduction of the writing or transmission created pursuant to this Section
2.10 may be substituted or used in lieu of the original writing or transmission
for any and all purposes for which the original writing or transmission could be
used, provided that such copy, facsimile telecommunication or reproduction shall
be a complete reproduction of the entire original writing or transmission.

            All voting, including on the election of directors but excepting
where otherwise required by law or the Certificate of Incorporation, may take
place via a voice vote. Any vote not taken by voice shall be taken by ballots,
each of which shall state the name of the stockholder or proxy voting and such
other information as may be required under the procedure established for the
meeting.

            2.11 ACTION TAKEN BY WRITTEN CONSENT. Holders of the Common Stock of
the Corporation may not take any action by written consent in lieu of a meeting.
Except as otherwise set forth in the certificate of designation for any class or
series of preferred stock, holders of a class or series of Preferred Stock
(including the Series X Preferred Stock and the Series Y Preferred Stock), when
voting or acting as a separate class or series, may take action by written
consent in lieu of a meeting.

                 or (C) by any stockholder of the Corporation who was a
                 stockholder of record at the time of giving of notice provided
                 for in this Section 2.12, who is entitled to vote at the
                 meeting and who complies with the notice procedures set forth
                 in this Section 2.12.

                     (ii) For nominations or other business to be properly
                 brought before an annual meeting by a stockholder pursuant to

                 stockholder must have given timely notice thereof in writing to
                 the Secretary of the Corporation and such other business must
                 otherwise be a proper matter for stockholder action. To be
                 timely, a stockholder's notice shall be delivered to the
                 Secretary at the principal executive offices of the Corporation

                 twentieth (120th) day nor earlier than the close of business on
                 the one hundred fiftieth (150th) day prior to the first
                 anniversary of the date of the proxy statement delivered to
                 stockholders in connection with the preceding year's annual
                 meeting; provided, however, that if either (1) the date of the
                 annual meeting is more than thirty (30) days before or more
                 than sixty (60) days after such an anniversary date or (2) no
                 proxy statement was delivered to stockholders in connection
                 with the preceding year's annual meeting, notice by the
                 stockholder to be timely must be so delivered not earlier than
                 the close of business on the ninetieth (90th) day prior to such
                 annual meeting and not later than the close of business on the
                 later of the sixtieth (60th) day prior to such annual meeting
                 or the close of business on the tenth (10th) day following the
                 day on which public announcement of the date of such meeting is
                 first made by the Corporation. Such stockholder's notice shall
                 set forth (a) as to each person whom the stockholder proposes
                 to nominate for election or reelection as a director, all
                 information relating to such person that is required to be
                 disclosed in solicitations of proxies for election of
                 directors, or is otherwise required, in each case pursuant to
                 Regulation 14A under the Securities Exchange Act of 1934 (the
                 "Exchange Act") (including such person's written consent to
                 being named in the proxy statement as a nominee and to serving
                 as a director if elected); (b) as to any other business that
                 the stockholder proposes to bring before the meeting, a brief
                 description of the business desired to be brought before the
                 meeting, the reasons for conducting such business at the
                 meeting and any material interest in such business of such
                 stockholder and the beneficial owner, if any, on whose behalf
                 the proposal is made; and (c) as to the stockholder giving the
                 notice and the beneficial owner, if any, on whose behalf the
                 nomination or proposal is made (i) the name and address of such
                 stockholder, as they appear on the Corporation's books, and of
                 such beneficial owner and (ii) the class and number of shares
                 of capital stock of the Corporation that are owned beneficially
                 and held of record by such stockholder and such beneficial
                 owner.

                     (iii) Notwithstanding anything in the second sentence of
                 paragraph (a)(ii) of this Section 2.12 to the contrary, in the
                 event that the number of directors to be elected to the Board
                 of Directors of the Corporation is increased and there is no
                 public announcement by the Corporation naming all of the
<PAGE>

                 nominees for director or specifying the size of the increased
                 Board of Directors at least one hundred twenty (120) days prior
                 to the first anniversary of the preceding year's annual meeting
                 (or, if the annual meeting is held more than thirty (30) days
                 before or sixty (60) days after such anniversary date, at least
                 ninety (90) days prior to such annual meeting), a stockholder's
                 notice required by this Section 2.12 shall also be considered
                 timely, but only with respect to nominees for any new positions
                 created by such increase, if it shall be delivered to the
                 Secretary at the principal executive office of the Corporation
                 not later than the close of business on the tenth (10th) day
                 following the day on which such public announcement is first
                 made by the Corporation.

                        (b) Special Meetings of Stockholders. Only such business
            shall be conducted at a special meeting of stockholders as shall
            have been brought before the meeting pursuant to the Corporation's
            notice of meeting. Nominations of persons for election to the Board
            of Directors may be made at a special meeting of stockholders at
            which directors are to be elected pursuant to the Corporation's
            notice of meeting (i) by or at the direction of the Board of
            Directors or (ii) provided that the Board of Directors has
            determined that directors shall be elected at such meeting, by any
            stockholder of the Corporation who is a stockholder of record at the
            time of giving of notice of the special meeting, who shall be
            entitled to vote at the meeting and who complies with the notice
            procedures set forth in this Section 2.12. If the Corporation calls
            a special meeting of stockholders for the purpose of electing one or
            more directors to the Board of Directors, any such stockholder may
            nominate a person or persons (as the case may be), for election to
            such position(s) as specified in the Corporation's notice of
            meeting, if the stockholder's notice required by paragraph (a)(ii)
            of this Section 2.12 shall be delivered to the Secretary at the
            principal executive offices of the Corporation not earlier than the
            ninetieth (90th) day prior to such special meeting nor later than
            the later of (x) the close of business on the sixtieth (60th) day
            prior to such special meeting or (y) the close of business on the
            tenth (10th) day following the day on which public announcement is
            first made of the date of such special meeting and of the nominees
            proposed by the Board of Directors to be elected at such meeting.

                 (c) General.

                     (i) Only such persons who are nominated in accordance with
                 the procedures set forth in this Section 2.12 shall be eligible
                 to serve as directors and only such business shall be conducted
                 at a meeting of stockholders as shall have been brought before
                 the meeting in accordance with the procedures set forth in this
                 Section 2.12. Except as otherwise provided by law, the
                 Certificate of Incorporation or these by-laws, the chairman of
                 the meeting shall have the power and duty to determine whether
                 a nomination or any business proposed to be brought before the
                 meeting was made or proposed, as the case may be, in accordance
                 with the procedures set forth in this Section 2.12 and, if any
                 proposed nomination or business is not in compliance herewith,
                 to declare that such defective proposal or nomination shall be
                 disregarded.
<PAGE>

                     (ii) For purposes of this Section 2.12, "public
                 announcement" shall mean disclosure in a press release reported
                 by the Dow Jones News Service, Associated Press, PR Newswire,
                 Business Wire or comparable national news service or in a
                 document publicly filed by the Corporation with the Securities
                 and Exchange Commission pursuant to Section 13, 14 or 15(d) of
                 the Exchange Act.

                     (iii) Notwithstanding the foregoing provisions of this
                 Section 2.12, a stockholder shall also comply with all
                 applicable requirements of the Exchange Act and the rules and
                 regulations thereunder with respect to the matters set forth
                 herein. Nothing in this Section 2.12 shall be deemed to affect
                 any rights (A) of stockholders to request inclusion of
                 proposals in the Corporation's proxy statement pursuant to Rule
                 14a-8 under the Exchange Act or (B) of the holders of any
                 series of Preferred Stock to elect directors under specified
                 circumstances.

3.          DIRECTORS.
            ---------
            3.1 NUMBER AND ELECTION. The number of directors which shall
constitute the whole Board of Directors shall be determined by resolution of the
Board of Directors, but in no event shall be less than three. The number of
directors may be decreased at any time and from time to time by a majority of
the directors then in office, but only to eliminate vacancies existing by reason
of the death, resignation, removal or expiration of the term of one or more
directors. The directors shall be elected at the annual meeting of the
stockholders (or, if so determined by the Board of Directors pursuant to Section
2.12, at a special meeting of stockholders) as provided in Section 2, and each
director elected shall hold office until his successor is elected and qualified.
Directors need not be stockholders of the Corporation.

            3.2 POWERS OF THE BOARD. The business of the Corporation shall be
managed by or under the direction of its Board of Directors, which may exercise

directed or required to be exercised or done by the stockholders.

Directors shall be held directly following each annual meeting of the
stockholders for the purpose of appointing the officers of the Corporation and
transacting such other business as shall be brought before such meeting. No
notice of the annual meeting shall be necessary to the newly elected directors
in order legally to constitute the meeting, provided a quorum shall be present.
In the event of the failure of the newly elected Board of Directors to meet
directly following the annual stockholders' meeting, the annual meeting of the
Board of Directors may be held at such time and place as shall be specified in a
notice given as hereinafter provided for special meetings of the Board of
Directors, or as shall be specified in a written waiver signed by all of the

the Chairman of the Board (if any), the president or the secretary and shall be
called by the president or secretary on the written request of any director.
Notice of any special meeting of directors shall be given to each director by
the secretary or by the officer or one of the directors requesting the meeting.
Notice shall be duly given to each director (i) by giving notice to such
director in person or by telephone at least 24 hours in advance of the meeting,
(ii) by sending a telegram or delivering written notice by facsimile
transmission, by e-mail or by hand, to his or her last known business, home or
e-mail address at least 24 hours in advance of the meeting, or (iii) by mailing
written notice to his or her last known business or home address at least 72
hours in advance of the meeting. A notice or waiver of notice of a meeting of
the Board of Directors need not specify the purposes of the meeting.

            3.7 QUORUM. At all meetings of the Board, a majority of the
directors shall constitute a quorum for the transaction of business, and the act
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the Certificate of Incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

            3.8 ACTION TAKEN BY WRITTEN CONSENT. Unless otherwise restricted by
the Certificate of Incorporation or these by-laws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all members of the board or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the board or committee.

            3.9 MEETINGS BY CONFERENCE CALL. Unless otherwise restricted by the
Certificate of Incorporation or these by-laws, members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting of the Board of Directors, or any committee, by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.

                        (a) The Board of Directors may, by resolution passed by
            a majority of the whole Board, designate one or more committees,
            each committee to consist of one or more of the directors of the
            Corporation. Such committee or committees shall have such name or
            names, powers and functions as may be determined from time to time
            by resolution adopted by the Board of Directors.
<PAGE>

                        (b) The Board of Directors may designate one or more
            directors as alternate members of any committee, who may replace any
            absent or disqualified member at any meeting of the committee. In
            the absence or disqualification of a member of a committee, the
            member or members thereof present at any meeting and not
            disqualified from voting, whether or not constituting a quorum, may
            unanimously appoint another member of the Board of Directors to act
            at the meeting in the place of any such absent or disqualified
            member.

                        (c) Any such committee, to the extent provided in the
            resolution of the Board of Directors and subject to the provisions
            of the General Corporation Law of the State of Delaware, shall have
            and may exercise all the powers and authority of the Board of
            Directors in the management of the business and affairs of the
            Corporation, and may authorize the seal of the Corporation to be

when required.

            3.12 COMPENSATION OF DIRECTORS. Unless otherwise restricted by the

the authority to fix the compensation of directors. The directors may be paid
their expenses, if any, of attendance at each meeting of the Board of Directors
and may be paid a fixed sum for attendance at each meeting of the Board of
Directors or a stated salary as director. No such payment shall preclude any
director from serving the Corporation in any other capacity and receiving
compensation therefor. Members of special or standing committees may be allowed
like compensation for serving on such committees and attending committee
meetings.

            3.13 VACANCIES. Unless and until filled by the stockholders, any

            6.2 STOCK LEGENDS. Every certificate for shares of stock which are
subject to any restriction on transfer pursuant to the Certificate of
Incorporation, these by-laws or any agreement to which the Corporation is a
party, shall have conspicuously noted on the face or back of the certificate

restriction and a statement that the Corporation will furnish a copy thereof to
the holder of such certificate upon written request and without charge. Every
certificate issued when the Corporation is authorized to issue more than one
class or series of stock shall set forth on its face or back either the full

rights of the shares of each class and series authorized to be issued or a

holder of such certificate upon written request and without charge.

            6.3 SIGNATURES ON CERTIFICATES. Any of or all the signatures on the
certificate may be facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer, transfer agent or registrar before such

as if such person were such officer, transfer agent or registrar at the date of
issue.

            6.4 LOST CERTIFICATES. The Board of Directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issuance of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or the owner's legal representative, to advertise the same in such
manner as it shall require and/or to give the Corporation a bond in such sum as
it may direct as indemnity against any claim that may be made against the
Corporation with respect to the certificate alleged to have been lost, stolen or
destroyed.

            6.5 TRANSFER OF STOCK. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignation or authority to
transfer, it shall be the duty of the Corporation to issue a
<PAGE>

new certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

            6.6 FIXED RECORD DATE. In order that the Corporation may determine
the stockholders entitled to notice of or to vote at any meeting of stockholders
or any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting, provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

            6.7 REGISTERED STOCKHOLDERS. The Corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

7.          GENERAL PROVISIONS.
            ------------------
            7.1 DIVIDENDS. Dividends upon the capital stock of the Corporation,
subject to the provisions of the Certificate of Incorporation, if any, may be
declared by the Board of Directors at any regular or special meeting, pursuant
to law. Dividends may be paid in cash, in property, or in shares of the capital
stock, subject to the provisions of the Certificate of Incorporation.

            7.2 RESERVES TO MEET CONTINGENCIES. Before payment of any dividend,
there may be set aside, out of any funds of the Corporation available for
dividends, such sum or sums as the directors from time to time, in their
absolute discretion, think proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the Corporation, or for such other purpose as the directors shall
think conducive to the interest of the Corporation, and the directors may modify
or abolish any such reserve in the manner in which it was created.

            7.3 CHECKS. All checks or demands for money and notes of the
Corporation shall be signed by such officer or officers or such other person or
persons as the Board of Directors may from time to time designate.

<PAGE>

            7.5 CORPORATE SEAL. The corporate seal shall have inscribed thereon
the name of the Corporation, the year of its organization and the words "Seal"
and "Delaware". The seal may be used by causing it or a facsimile thereof to be
impressed or affixed or reproduced or otherwise.

8.          INDEMNIFICATION.
            ---------------
            8.1 ACTION AGAINST PARTY BECAUSE OF CORPORATE POSITION. The
Corporation shall indemnify, to the fullest extent permitted by applicable law
as it presently exists or may hereafter be amended, any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was a director or officer of the Corporation,
or such director or officer of the Corporation is or was serving at the request
of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise or non-profit
entity, against expenses (including attorneys' fees and disbursements, inclusive
of any appeal), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such claim, action, suit
or proceeding if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful. The termination of any claim, action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner that he reasonably believed
to be in or not opposed to the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had reasonable cause to believe
that his conduct was unlawful.

            8.2 ACTION BY OR IN THE RIGHT OF CORPORATION. The Corporation shall
indemnify any person who is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he is
or was a director or officer of the Corporation, or such director or officer of
the Corporation is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise or non-profit entity, against expenses
(including attorneys' fees and disbursements, inclusive of any appeal) actually
and reasonably incurred by him in connection with the defense or settlement of
such claim, action or suit if he acted in good faith and in a manner he
reasonably believed to be in or is not opposed to the best interests of the
Corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that a court of
competent jurisdiction (the "Court") in which such claim, action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court
shall deem proper.

            8.3 REIMBURSEMENT IF SUCCESSFUL. To the extent that a present or
former director or officer of the Corporation has been successful on the merits
or otherwise in defense of any
<PAGE>

action, suit or proceeding referred to in Sections 8.1 or 8.2, or in defense of
any claims, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees and disbursements, inclusive of any appeal)
actually and reasonably incurred by such person in connection therewith,
notwithstanding that such person has not been successful (on the merits or
otherwise) on any other claim, issue or matter in any such claim, action, suit
or proceeding.

            8.4 AUTHORIZATION. Any indemnification under Sections 8.1 and 8.2
(unless ordered by a court) shall be made by the Corporation only as authorized
in the specific case upon a determination that indemnification of the present or
former director, officer, employee or agent is proper in the circumstances
because such person has met the applicable standard of conduct set forth in
Sections 8.1 and 8.2. Such determination shall be made, with respect to a person
who is a director or officer at the time of such determination, (a) by a
majority vote of the directors who are or were not parties to such action, suit
or proceeding, even though less than a quorum, or (b) by a committee of such
directors designated by majority vote of such directors, even though less than a
quorum, or (c) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (d) by the stockholders.

            8.5 ADVANCED REIMBURSEMENT. Expenses (including attorneys' fees and
disbursements, inclusive of any appeal) incurred by an officer or director of
the Corporation in defending any pending or threatened civil, criminal,
administrative or investigative action, suit or proceeding shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Corporation as authorized in
this, or granted pursuant to, Section 8. Such expenses (including attorneys'
fees) incurred by former directors and officers or other employees or agents of
the Corporation may be so paid upon such terms and conditions, if any, as the
Board of Directors deems appropriate.

            8.6 INDEMNIFICATION NO EXCLUSIVE. The indemnification and
advancement of expenses provided by, or granted pursuant to, this Section 8
shall not be deemed exclusive of any other rights to which those indemnified may
be entitled under any statute, rule of law, provision of the Certificate of
Incorporation, as it may be amended, By-law, agreement, vote of stockholders or
disinterested directors, or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person. Where such other provision
provides broader rights of indemnification than these by-laws, said other
provision shall control.

            8.7 INDEMNIFICATION OF EMPLOYEES AND AGENTS. The Corporation may, to
the extent authorized from time to time by the Board of Directors, provide
rights to indemnification and to the advancement of expenses to employees and
agents of the Corporation, and to such employees and agents serving at the
request of the Corporation as a director, partner, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise or
non-profit entity, similar to those conferred in this Section 8 to directors and
officers of the Corporation.
<PAGE>

            8.8 INSURANCE. The Corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, partner, officer, employee agent of another
corporation, partnership, joint venture, trust or other enterprise or non-profit
entity against any liability asserted against such person and incurred by such
person in any such capacity, or arising out of such person's status as such,
whether or not the Corporation would have the power to indemnify him against
such liability under the provisions of this Section 8.

9.          AMENDMENTS.
            ----------
            9.1 BY THE BOARD OF DIRECTORS. Except as is otherwise set forth in
these by-laws, these by-laws may be altered, amended or repealed, or new by-laws
may be adopted, by the affirmative vote of a majority of the directors present
at any regular or special meeting of the Board of Directors at which a quorum is

the capital stock of the Corporation issued and outstanding and entitled to vote

stockholders provided notice of such alteration, amendment, repeal or adoption
of new by-laws shall have been stated in the notice of such special meeting.EXHIBIT 4.03
                                                                    ------------

                                  DSL.NET, INC.

            AMENDED AND RESTATED 2001 STOCK OPTION AND INCENTIVE PLAN

SECTION 1. PURPOSE.
-------------------

           The purpose of the Amended and Restated 2001 Stock Option and
Incentive Plan (the "Plan") is to secure for DSL.net, Inc., (the "Company"), its
parent (if any) and any subsidiaries of the Company (collectively the "Related
Corporations") the benefits arising from capital stock ownership by those
employees, directors, officers and consultants of the Company and any Related
Corporations who will be responsible for the Company's future growth and
continued success.

           The Plan will provide a means whereby (a) employees of the Company
and any Related Corporations may purchase stock in the Company pursuant to
options which qualify as "incentive stock options" ("Incentive Stock Options")
under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
(b) directors, employees and consultants of the Company and any Related
Corporations may purchase stock in the Company pursuant to options granted
hereunder which do not qualify as Incentive Stock Options ("Non-Qualified
Options"); (c) directors, employees and consultants of the Company and any
Related Corporations may be awarded stock in the Company ("Awards"); (d)
directors, employees and consultants of the Company and any Related Corporations
may receive stock appreciation rights ("SARs"); and (e) directors, employees and
consultants of the Company and any Related Corporations may make direct
purchases of stock in the Company ("Purchases"). Both Incentive Stock Options
and Non-Qualified Options are referred to hereafter individually as an "Option"
and collectively as "Options." As used herein, the terms "parent" and
"subsidiary" mean "parent corporation" and "subsidiary corporation" as those
terms are defined in Section 424 of the Code. Options, Awards, SARs and
Purchases are referred to hereafter individually as a "Plan Benefit" and
collectively as "Plan Benefits." Directors, employees and consultants of the
Company and any Related Corporations are referred to herein as "Participants."

SECTION 2. ADMINISTRATION.
--------------------------

     2.1 BOARD OF DIRECTORS AND THE COMMITTEE. The Plan will be administered by
the Board of Directors of the Company whose construction and interpretation of
the terms and provisions hereof shall be final and conclusive. Any director to
whom a Plan Benefit is awarded shall be ineligible to vote upon his or her Plan
Benefit, but Plan Benefits may be granted any such director by a vote of the
remainder of the directors, except as limited below. The Board of Directors may
in its sole discretion grant Options, issue shares upon exercise of such
Options, grant Awards, grant SARs and approve Purchases, all as provided in the
Plan. The Board of

<PAGE>

Directors shall have authority, subject to the express provisions of the Plan,
to construe the Plan and its related agreements, to prescribe, amend and rescind
rules and regulations relating to the Plan, to determine the terms and
provisions of the respective Option, Award, SAR and Purchase agreements, which
need not be identical, and to make all other determinations in the judgment of
the Board of Directors necessary or desirable for the administration of the
Plan. The Board of Directors may correct any defect or supply any omission or
reconcile any inconsistency in the Plan or in any related agreement in the
manner and to the extent it shall deem expedient to carry the Plan into effect
and it shall be the sole and final judge of such expediency. No director shall
be liable for any action or determination made in good faith. The Board of
Directors may delegate to the President or Chief Executive Officer of the
Company the power to grant options to non-officers in accordance with written
guidelines approved by the Board of Directors. In addition, the Board of
Directors may delegate any or all of its powers under the Plan to a Compensation
Committee or other Committee (the "Committee") appointed by the Board of
Directors consisting of at least two members of the Board of Directors. If the
Company has a class of stock registered pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), then members of the
Committee shall at all times be: (i) "outside directors" as such term is defined
in Treas. Reg. ss. 1.162-27(e)(3) (or any successor regulation); and (ii)
"non-employee directors" within the meaning of Rule 16b-3 (or any successor
rule) under the Exchange Act, as such terms are interpreted from time to time;
provided, however that if the members of the Committee do not meet the
requirements set forth in (ii) above, then all decisions and acts of the
Committee shall be subject to and effective upon the approval of the Board of
Directors. If a Committee meeting the requirements of (i) and (ii) above is so
appointed, all references to the Board of Directors herein shall mean and relate
to such Committee, unless the context otherwise requires; provided, however,
that if a Committee is appointed that does not meet the requirements of (i) and
(ii) above, then all decisions and acts of the Committee shall be subject to and
effective upon the approval of the Board of Directors.

     2.2 Compliance with Section 162(m) of the Code. Section 162(m) of the Code,
added by the Omnibus Budget Reconciliation Act of 1993, generally limits the tax
deductibility to publicly held companies of compensation in excess of $1,000,000
paid to certain "covered employees" ("Covered Employees"). If the Company is
subject to Section 162(m) of the Code, it is the Company's intention to preserve
the deductibility of such compensation to the extent it is reasonably
practicable and to the extent it is consistent with the Company's compensation
objectives. For purposes of this Plan, Covered Employees of the Company shall be
those employees of the Company described in Section 162(m)(3) of the Code.

SECTION 3. ELIGIBILITY.
-----------------------

     3.1 INCENTIVE STOCK OPTIONS. Participants who are employees shall be
eligible to receive Incentive Stock Options pursuant to the Plan; provided that
no person shall be granted any Incentive Stock Option under the Plan who, at the
time such Option is granted, owns, directly or indirectly, Common Stock of the
Company possessing more than 10% of the total combined voting power of all
classes of stock of the Company or of its Related Corporations, unless the
requirements of Section 6.6(b) hereof are satisfied. In determining whether this
10%

                                        2
<PAGE>

threshold has been reached, the stock attribution rules of Section 424(d) of the
Code shall apply. Directors who are not regular employees are not eligible to
receive Incentive Stock Options.

     3.2 NON-QUALIFIED OPTIONS, AWARDS, SARS AND PURCHASES. Non-Qualified
Options, Awards, SARs and authorizations to make Purchases may be granted to any
Participant.

     3.3 GENERALLY. The Board of Directors may take into consideration a
Participant's individual circumstances in determining whether to grant an
Incentive Stock Option, a Non-Qualified Option, an Award or an SAR or to approve
a Purchase. Granting of any Option, Award or SAR or approval of any Purchase for
any individual shall neither entitle that individual to, nor disqualify that
individual from, participation in any other grant of Plan Benefits.

SECTION 4. STOCK SUBJECT TO PLAN.
---------------------------------

           Subject to adjustment as provided in Sections 10 and 11 hereof, the
stock to be offered under the Plan shall consist of shares of the Company's
Common Stock, par value $.0005 per share, and the maximum number of shares of
stock which will be reserved for issuance, and in respect of which Plan Benefits
may be granted pursuant to the provisions of the Plan, shall not exceed in the
aggregate 20,000,000 shares. Such shares may be authorized and unissued shares
or may be treasury shares. If an Option or SAR granted hereunder shall expire or
terminate for any reason without having been exercised in full, or if the
Company shall reacquire any unvested shares issued pursuant to Awards or
Purchases, the unpurchased shares subject thereto and any unvested shares so
reacquired shall again be available for subsequent grants of Plan Benefits under
the Plan. Stock issued pursuant to the Plan may be subject to such restrictions
on transfer, repurchase rights or other restrictions as shall be determined by
the Board of Directors.

SECTION 5. GRANTING OF OPTIONS, AWARDS AND SARS AND APPROVALS OF PURCHASES.
---------------------------------------------------------------------------

           Options, Awards and SARs may be granted and Purchases may be approved
under the Plan at any time on or after November 28, 2001 and prior to November
28, 2011; provided, however, that prior to the date the Plan is first approved
by the Company's stockholders (i) no Incentive Stock Options shall be granted
pursuant to the Plan and (ii) no Plan Benefits shall be granted to a director or
an officer of the Company or any Related Corporations, unless with respect to
such grant to an officer, such grant is an inducement essential to such person's
entering into one or more employment agreements with the Company or any Related
Corporations as a new employee. The date of grant of an Option, Award or SAR or
approval of a Purchase under the Plan will be the date specified by the Board of
Directors at the time the Board of Directors grants such Option, Award or SAR or
approves such Purchase; provided, however, that such date shall not be prior to
the date on which the Board of Directors takes such action. The Board of
Directors shall have the right, with the consent of a Participant, to convert an
Incentive Stock Option granted under the Plan to a Non-Qualified Option pursuant
to Section 6.7. Plan Benefits may be granted alone or in addition to other
grants under the Plan.

SECTION 6. SPECIAL PROVISIONS APPLICABLE TO OPTIONS AND SARS.
-------------------------------------------------------------

           6.1 PURCHASE PRICE AND SHARES SUBJECT TO OPTIONS AND SARS.

                     (a) The purchase price per share of stock deliverable upon
           the exercise of an Option shall be determined by the Board of
           Directors, provided, however, that, in the case of an Incentive Stock
           Option, the exercise price shall not be less than 100% of the fair
           market value of such stock on the day the option is granted (except
           as modified in Section 6.6(b) hereof). The Board of Directors may
           delegate to the Chief Executive Officer of the Company the power to
           determine the exercise price of an option in accordance with written
           guidelines approved by the Board of Directors.

                     (b) Options granted under the Plan may provide for the
           payment of the exercise price by delivery of (i) cash or a check
           payable to the order of the Company in an amount equal to the
           exercise price of such Options, (ii) shares of Common Stock of the
           Company owned by the Participant having a fair market value equal in
           amount to the exercise price of the Options being exercised, or (iii)
           any combination of (i) and (ii). The fair market value of any shares
           of the Company's Common Stock which may be delivered upon exercise of
           an Option shall be determined by the Board of Directors. The Board of
           Directors may also permit Participants, either on a selective or
           aggregate basis, to simultaneously exercise Options and sell the
           shares of Common Stock thereby acquired, either to the Company or
           pursuant to a brokerage or similar arrangement, approved in advance
           by the Board of Directors, and to use the proceeds from such sale as
           payment of the purchase price of such shares.

                     (c) If, at the time an Option is granted under the Plan,
           the Company's Common Stock is publicly traded, "fair market value"
           shall be determined as of the last business day for which the prices
           or quotes discussed in this sentence are available prior to the date
           such Option is granted (the "Determination Date") and shall mean (i)
           the average (on the Determination Date) of the high and low prices of
           the Common Stock on the principal national securities exchange on
           which the Common Stock is traded, if such Common Stock is then traded
           on a national securities exchange; (ii) the last reported sale price
           (on the Determination Date) of the Common Stock on the Nasdaq Stock
           Market if the Common Stock is not then traded on a national
           securities exchange; or (iii) the closing bid price (or average of
           bid prices) last quoted (on the Determination Date) by an established
           quotation service for over-the-counter securities, if the Common
           Stock is not reported on the Nasdaq Stock Market. However, if the
           Common Stock is not publicly traded at the time an Option is granted
           under the Plan, "fair market value" shall be deemed to be the fair
           value of the Common Stock as determined by the Board of Directors
           after taking into consideration all factors which it deems
           appropriate, including, without limitation, recent sale and offer
           prices of the Common Stock in private transactions negotiated at
           arm's length.

                                        4
<PAGE>

                     (d) If the Company is subject to Section 162(m) of the
           Code, the maximum number of shares with respect to which Options or
           SARs may be granted to any employee, including any cancellations or
           repricings which may occur, shall be limited to 3,000,000 shares in
           any calendar year.

           6.2 DURATION OF OPTIONS AND SARS. Subject to Section 6.6(b) hereof,
each Option and SAR and all rights thereunder shall be expressed to expire on
such date as the Board of Directors may determine, but in no event later than
ten years from the day on which the Option or SAR is granted and shall be
subject to earlier termination as provided herein.

           6.3 EXERCISE OF OPTIONS AND SARS.

                     (a) Subject to Section 6.6(b) hereof, each Option and SAR
           granted under the Plan shall be exercisable at such time or times and
           during such period as shall be set forth in the instrument evidencing
           such Option or SAR. To the extent that an Option or SAR is not
           exercised by a Participant when it becomes initially exercisable, it
           shall not expire but shall be carried forward and shall be
           exercisable, on a cumulative basis, until the expiration of the
           exercise period. No partial exercise may be for less than ten (10)
           full shares of Common Stock (or its equivalent).

                     (b) The Board of Directors shall have the right to
           accelerate the date of exercise of any installments of any Option or
           SAR; provided that the Board of Directors shall not accelerate the
           exercise date of any installment of any Option granted to a
           Participant as an Incentive Stock Option (and not previously
           converted into a Non-Qualified Option pursuant to Section 6.7) if
           such acceleration would violate the annual vesting limitation
           contained in Section 422(d)(1) of the Code, which provides generally
           that the aggregate fair market value (determined at the time the
           Option is granted) of the stock with respect to which Incentive Stock
           Options granted to any Participant are exercisable for the first time
           by such Participant during any calendar year (under all plans of the
           Company and any Related Corporations) shall not exceed $100,000. To
           the extent the aggregate fair market value of the stock with respect
           to which Incentive Stock Options granted to any Participant are
           exercisable for the first time by such Participant during any
           calendar year (under all plans of the Company and any Related
           Corporations) exceeds $100,000, such Options shall be treated as
           Non-Qualified Options.

           6.4 NONTRANSFERABILITY OF OPTIONS AND SARS.

           No Option or SAR granted under the Plan shall be assignable or
transferable by the Participant, either voluntarily or by operation of law,
except by will or the laws of descent and distribution or, with respect to
Non-Qualified Options and SARs, pursuant to a qualified domestic relations order
as defined by the Code or Title I of the Employee Retirement Income Security Act
("ERISA") or the rules promulgated thereunder or unless the Participant's
non-qualified stock option agreement granting such options (the "Non-Qualified
Stock Option Agreement") or the Participant's SAR agreement granting such SARs
(the "SAR Agreement") provides otherwise. Unless otherwise provided by the
Non-Qualified Stock Option Agreement

                                        5
<PAGE>

or the SAR Agreement, during the life of the Participant, the Option or SAR
shall be exercisable only by him or her. If any Participant should attempt to
dispose of or encumber his or her Options or SARs, other than in accordance with
the applicable terms of a Non-Qualified Stock Option Agreement or SAR Agreement,
his or her interest in such Options or SARs shall terminate.

           6.5 EFFECT OF TERMINATION OF EMPLOYMENT OR DEATH.

                     (a) Except as provided in any applicable option agreement,
           if a Participant ceases to be employed by the Company or a Related
           Corporation for any reason, including retirement but other than
           death, any Option or SAR granted to such Participant under the Plan
           shall immediately terminate; provided, however, that any portion of
           such Option or SAR which was otherwise exercisable on the date of
           termination of the Participant's employment may be exercised within
           the three-month period following the date on which the Participant
           ceased to be so employed, but in no event after the expiration of the
           exercise period. Any such exercise may be made only to the extent of
           the number of shares subject to the Option or SAR which were
           purchasable on the date of such termination of employment. If the
           Participant dies during such three-month period, the Option or SAR
           shall be exercisable by the Participant's personal representatives,
           heirs or legatees to the same extent and during the same period that
           the Participant could have exercised the Option or SAR on the date of
           his or her death.

                     (b) If the Participant dies while an employee of the
           Company or any Related Corporation, any Option or SAR granted to such
           Participant under the Plan shall be exercisable by the Participant's
           personal representatives, heirs or legatees, for the purchase of that
           number of shares and to the same extent that the Participant could
           have exercised the Option or SAR on the date of his or her death. The
           Option or SAR or any unexercised portion thereof shall terminate
           unless so exercised prior to the earlier of the expiration of six
           months from the date of such death or the expiration of the exercise
           period.

           6.6 DESIGNATION OF INCENTIVE STOCK OPTIONS; LIMITATIONS.

           Options granted under the Plan which are intended to be Incentive
Stock Options qualifying under Section 422 of the Code shall be designated as
Incentive Stock Options and shall be subject to the following additional terms
and conditions:

                     (a) Dollar Limitation. The aggregate fair market value
           (determined at the time the option is granted) of the Common Stock
           for which Incentive Stock Options are exercisable for the first time
           during any calendar year by any person under the Plan (and all other
           incentive stock option plans of the Company and any Related
           Corporations) shall not exceed $100,000. To the extent the aggregate
           fair market value of the Common Stock for which Incentive Stock
           Options granted to any Participant are exercisable for the first time
           by such Participant during any calendar year (under all plans of the
           Company and any Related Corporations) exceeds $100,000, such Options
           shall be treated as Non-

                                        6
<PAGE>

           Qualified Options. In the event that Section 422(d)(1) of the Code is
           amended to alter the limitation set forth therein so that following
           such amendment such limitation shall differ from the limitation set
           forth in this Section 6.6(a), the limitation of this Section 6.6(a)
           shall be automatically adjusted accordingly.

                     (b) 10% Stockholder. If any employee to whom an Incentive
           Stock Option is to granted pursuant to the provisions of the Plan is
           on the date of grant the owner of stock possessing more than 10% of
           the total combined voting power of all classes of stock of the
           Company or any Related Corporations, then the following special
           provisions shall be applicable to the Incentive Stock Option granted
           to such individual:

                               (i) The option 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 on the date of grant; and

                               (ii) The option exercise period shall not exceed
                     five years from the date of grant.

           In determining whether the 10% threshold has been reached, the stock
           attribution rules of Section 424(d) of the Code shall apply.

                     (c) Except as modified by the preceding provisions of this
           Section 6.6, all of the provisions of the Plan shall be applicable to
           Incentive Stock Options granted hereunder.

           6.7 CONVERSION OF INCENTIVE STOCK OPTIONS INTO NON-QUALIFIED OPTIONS;
TERMINATION OF INCENTIVE STOCK OPTIONS. The Board of Directors, at the written
request of any Participant, may in its discretion take such actions as may be
necessary to convert such Participant's Incentive Stock Options (or any
installments or portions of installments thereof) that have not been exercised
on the date of conversion into Non-Qualified Options at any time prior to the
expiration of such Incentive Stock Options, regardless of whether the
Participant is an employee of the Company or a Related Corporation at the time
of such conversion. Such actions may include, but not be limited to, extending
the exercise period or reducing the exercise price of the appropriate
installments of such Options. At the time of such conversion, the Board of
Directors (with the consent of the Participant) may impose such conditions on
the exercise of the resulting Non-Qualified Options as the Board of Directors in
its discretion may determine, provided that such conditions shall not be
inconsistent with the Plan. Nothing in the Plan shall be deemed to give any
Participant the right to have such Participant's Incentive Stock Options
converted into Non-Qualified Options, and no such conversion shall occur until
and unless the Board of Directors takes appropriate action. The Board of
Directors, with the consent of the Participant, may also terminate any portion
of any Incentive Stock Option that has not been exercised at the time of such
termination.

           6.8 STOCK APPRECIATION RIGHTS. A SAR is the right to receive, without
payment, an amount equal to the excess, if any, of the fair market value of a
share of Common Stock on the

                                        7
<PAGE>

date of exercise over the grant price, which amount will be multiplied by the
number of shares with respect to which the SARs shall have been exercised. The
grant of SARs under the Plan shall be subject to the following terms and
conditions and shall contain such additional terms and conditions, not
inconsistent with the express terms of the Plan, as the Board of Directors shall
deem desirable:

                     (a) Grant. SARs may be granted in tandem with, in addition
           to or completely independent of any Plan Benefit.

                     (b) Grant Price. The grant price of a SAR may be the fair
           market value of a share of Common Stock on the date of grant or such
           other price as the Board of Directors may determine.

                     (c) Exercise. A SAR may be exercised by a Participant in
           accordance with procedures established by the Board of Directors or
           as otherwise provided in any agreement evidencing any SARs. The Board
           of Directors may provide that an SAR shall be automatically exercised
           on one or more specified dates.

                     (d) Form of Payment. Payment upon exercise of an SAR may be
           made in cash, in shares of Common Stock or any combination thereof,
           as the Board of Directors shall determine.

                     (e) Fair Market Value. Fair market value shall be
           determined in accordance with Section 6.1(c) with the "Determination
           Date" being determined by reference to the date of grant or the date
           of exercise of an SAR, as applicable.

           6.9 RIGHTS AS A STOCKHOLDER.

           The holder of an Option or SAR shall have no rights as a stockholder
with respect to any shares covered by the Option or SAR until the date of issue
of a stock certificate to him or her for such shares. Except as otherwise
expressly provided in the Plan, no adjustment shall be made for dividends or
other rights for which the record date is prior to the date such stock
certificate is issued.

           6.10 SPECIAL PROVISIONS APPLICABLE TO NON-QUALIFIED OPTIONS AND SARS
GRANTED TO COVERED EMPLOYEES.

           If the Company is subject to Section 162(m) of the Code, in order for
the full value of Non-Qualified Options or SARs granted to Covered Employees to
be deductible by the Company for federal income tax purposes, the Company may
intend for such Non-Qualified Options or SARs to be treated as "qualified
performance-based compensation" as described in Treas. Reg. ss.1.162-27(e) (or
any successor regulation). In such case, Non-Qualified Options or SARs granted
to Covered Employees shall be subject to the following additional requirements:

                     (a) such options and rights shall be granted only by the
           Committee; and

                                        8
<PAGE>

                     (b) the exercise price of such Options and the grant price
           of such SARs granted shall in no event be less than the fair market
           value of the Common Stock as of the date of grant of such Options or
           SARs.

SECTION 7. SPECIAL PROVISIONS APPLICABLE TO AWARDS
--------------------------------------------------

           7.1 GRANTS OF AWARDS. The Board of Directors may grant a Participant
an Award subject to such terms and conditions as the Board of Directors deems
appropriate, including, without limitation, restrictions on the pledging, sale,
assignment, transfer or other disposition of such shares and the requirement
that the Participant forfeit all or a portion of such shares back to the Company
upon termination of employment.

           7.2 CONDITIONS.  Approvals of Awards may be subject to the followin
conditions:

                     (a) Each Participant receiving an Award shall enter into an
           agreement (a "Stock Restriction Agreement") with the Company, if
           required by the Board of Directors, in a form specified by the Board
           of Directors agreeing to such terms and conditions of the Award as
           the Board of Directors deems appropriate.

                     (b) Shares issued and transferred to a Participant pursuant
           to an Award may, if required by the Board of Directors, be deposited
           with the Treasurer or other officer of the Company designated by the
           Board of Directors to be held until the lapse of the restrictions
           upon such shares, and each Participant shall execute and deliver to
           the Company stock powers enabling the Company to exercise its rights
           hereunder.

                     (c) Certificates for shares issued pursuant to an Award
           shall, if the Company shall deem it advisable, bear a legend to the
           effect that they are issued subject to specified restrictions.

                     (d) Certificates representing the shares issued pursuant to
           an Award shall be registered in the name of the Participant and shall
           be owned by such Participant. Such Participant shall be the holder of
           record of such shares for all purposes, including voting and receipt
           of dividends paid with respect to such shares.

           7.3 NONTRANSFERABILITY. Shares issued pursuant to an Award may not be
sold, assigned, transferred, alienated, commuted, anticipated, or otherwise
disposed of (except, subject to the provisions of such Participant's Stock
Restriction Agreement, 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 of ERISA or the rules promulgated thereunder), or pledged or hypothecated as
collateral for a loan or as security for the performance of any obligation, or
be otherwise encumbered, and are not subject to attachment, garnishment,
execution or other legal or equitable process, prior to the lapse of
restrictions on such shares, and any attempt at action in contravention of this
Section shall be null and void. If any Participant should attempt to dispose

                                        9
<PAGE>

of or encumber his or her shares issued pursuant to an Award prior to the lapse
of the restrictions imposed on such shares, his or her interest in such shares
shall terminate.

           7.4 EFFECT OF TERMINATION OF EMPLOYMENT OR DEATH ON AWARDS. If, prior
to the lapse of restrictions applicable to Awards, the Participant ceases to be
an employee of the Company or the Related Corporations for any reason, Awards to
such Participant, as to which restrictions have not lapsed, shall be forfeited
to the Company, effective on the date of the Participant's termination of
employment. The Board of Directors shall have the sole power, consistent with
applicable laws, to decide in each case to what extent leaves of absence shall
be deemed a termination of employment.

SECTION 8. SPECIAL PROVISIONS APPLICABLE TO PURCHASES.
------------------------------------------------------

           All approvals of Purchases which provide that the Company has a right
to repurchase the shares subject to such Purchase (the "Restricted Shares")
shall be subject to the terms and conditions set forth in the related agreement
(the "Stock Purchase Restriction Agreement") approved by the Board of Directors,
and shall be subject to the other terms and conditions of this Section 8.

           8.1 CONDITIONS. All approvals of Purchases shall be subject to the
following conditions:

                     (a) Prior to the issuance and transfer of Restricted
           Shares, the Participant shall pay to the Company the purchase price
           (the "Purchase Price") of the Restricted Shares in cash or in such
           other manner as shall be as approved by the Board of Directors.

                     (b) Restricted Shares issued and transferred to a
           Participant may, if required by the Board of Directors, be deposited
           with the Treasurer or other officer of the Company designated by the
           Board of Directors to be held until the lapse of the restrictions
           upon such Restricted Shares, and each Participant shall execute and
           deliver to the Company stock powers enabling the Company to exercise
           its rights hereunder.

                     (c) Certificates for Restricted Shares shall, if the
           Company shall deem it advisable, bear a legend to the effect that
           they are issued subject to specified restrictions.

                     (d) Certificates representing the Restricted Shares shall
           be registered in the name of the Participant and shall be owned by
           such Participant. Such Participant shall be the holder of record of
           such Restricted Shares for all purposes, including voting and receipt
           of dividends paid with respect to such Restricted Shares.

           8.2 NONTRANSFERABILITY. A Participant's Restricted Shares may not be
sold, assigned, transferred, alienated, commuted, or otherwise disposed of
(except, subject to the provisions of such Participant's Stock Purchase
Restriction Agreement, 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 of ERISA or the rules promulgated thereunder), or pledged or hypothecated as
collateral for a loan or as security for the performance of any obligation, or
be otherwise encumbered, and are not subject to attachment, garnishment,
execution or other legal or equitable process, prior to the lapse of
restrictions on such Restricted Shares, and any attempt at action in
contravention of this Section shall be null and void. If any Participant should
attempt to dispose of or encumber his or her Restricted Shares prior to the
lapse of the restrictions imposed on such Restricted Shares, his or her interest
in the Restricted Shares awarded to him or her shall terminate.

SECTION 9. REQUIREMENTS OF LAW.
-------------------------------

           9.1 VIOLATIONS OF LAW. No shares shall be issued and delivered upon
exercise of any Option or the making of any Award or Purchase or the payment of
any SAR unless and until, in the opinion of counsel for the Company, any
applicable registration requirements of the Securities Act of l933, as amended,
any applicable listing requirements of any national securities exchange on which
stock of the same class is then listed, and any other requirements of law or of
any regulatory bodies having jurisdiction over such issuance and delivery, shall
have been fully complied with. Each Participant may, by accepting Plan Benefits,
be required to represent and agree in writing, for himself or herself and for
his or her transferees by will or the laws of descent and distribution, that the
stock acquired by him, her or them is being acquired for investment. The
requirement for any such representation may be waived at any time by the Board
of Directors.

           9.2 COMPLIANCE WITH RULE 16B-3. If the Company has a class of stock
registered pursuant to Section 12 of the Exchange Act, the intent of this Plan
is to qualify for the exemption provided by Rule 16b-3 under the Exchange Act.
To the extent any provision of the Plan does not comply with the requirements of
Rule 16b-3, it shall be deemed inoperative to the extent permitted by law and
deemed advisable by the Board of Directors and shall not affect the validity of
the Plan. In the event Rule 16b-3 is revised or replaced, the Board of Directors
may exercise discretion to modify this Plan in any respect necessary to satisfy
the requirements of the revised exemption or its replacement.

SECTION 10. RECAPITALIZATION.
-----------------------------

           In the event that dividends are payable in Common Stock of the
Company or in the event there are splits, sub-divisions or combinations of
shares of Common Stock of the Company, the number of shares available under the
Plan shall be increased or decreased proportionately, as the case may be, and
the number of shares deliverable upon the exercise thereafter of any Option
previously granted shall be increased or decreased proportionately, as the case
may be, without change in the aggregate purchase price, and the number of shares
to which granted SARs relate shall be increased or decreased proportionately, as
the case may be, and the grant price of such SARs shall be decreased or
increased proportionately, as the case may be.

SECTION 11. REORGANIZATION.
---------------------------

           (a) In case the Company is merged or consolidated with another
corporation and the Company is not the surviving corporation, or, in case the
property or stock of the Company is acquired by any other corporation, or in
case of a reorganization or 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 hereunder, shall, as to outstanding Plan Benefits,
either (i) make appropriate provision for the protection of any such outstanding
Plan Benefits by the substitution on an equitable basis of appropriate stock of
the Company or of the merged, consolidated or otherwise reorganized corporation
which will be issuable in respect of the shares of Common Stock of the Company,
provided only that the excess of the aggregate fair market value of the shares
subject to the Plan Benefits immediately after such substitution over the
purchase price thereof is not more than the excess of the aggregate fair market
value of the shares subject to such Plan Benefits immediately before such
substitution over the purchase price thereof, (ii) upon written notice to the
Participants, provide that all unexercised Plan Benefits must be exercised
within a specified number of days of the date of such notice or such Plan
Benefits will be terminated, or (iii) upon written notice to the Participants,
provide that the Company or the merged, consolidated or otherwise reorganized
corporation shall have the right, upon the effective date of any such merger,
consolidation, sale of assets or reorganization, to purchase all Plan Benefits
held by each Participant and unexercised as of that date at an amount equal to
the aggregate fair market value on such date of the shares subject to the Plan
Benefits held by such Participant over the aggregate purchase price therefor,
such amount to be paid in cash or, if stock of the merged, consolidated or
otherwise reorganized corporation is issuable in respect of the shares of the
Common Stock of the Company, then, in the discretion of the Board of Directors,
in stock of such merged, consolidated or otherwise reorganized corporation equal
in fair market value to the aforesaid amount. In any such case the Board of
Directors shall, in good faith, determine fair market value and may, in its
discretion, advance the lapse of any waiting or installment periods and exercise
dates.

           (b) Notwithstanding anything herein to the contrary, in the event
that following or in connection with a Change-in-Control (as defined below), a
Participant's employment with, or service as a director or consultant of, the
Company is (i) terminated by the Company for any reason other than Cause (as
defined below), or (ii) terminated by the Participant for Good Reason (as
defined below), any portion of a Participant's Plan Benefit which would
otherwise vest or become exercisable solely with the passage of time and the
Participant's continued employment with or service as a director or consultant
of the Company, shall immediately vest and become fully exercisable and all
rights relevant to such Plan Benefit shall accrue immediately to such
Participant, unless otherwise explicitly provided in the applicable Award
agreement. The term "Cause" shall mean (i) habitual intoxication, (ii) illegal
drug use or addiction, (iii) conviction of a felony (or plea of guilty or nolo
contendere), (iv) material failure or inability to perform one's agreements,
duties or obligations as an employee, director or consultant, other than from
illness or injury, and (v) willful misconduct or negligence in the performance
of one's agreements, duties or obligations as an employee, director or
consultant. The term "Change-in-Control" shall mean: (i) any sale, lease,
exchange or other transfer (in one transaction or series of transactions) of all
or substantially all of the assets of the Company; (ii) individuals who, as of
the date hereof, constitute the entire Board of Directors of the Company (the
"Incumbent Directors") cease for

                                       12
<PAGE>

any reason to constitute at least a majority of the Board of Directors, provided
that any individual becoming a director subsequent to the date hereof whose
election or nomination for election was approved by a vote of at least a
majority of the then Incumbent Directors shall be, for the purposes of this
provision, considered as though such individual were an Incumbent Director;
(iii) any consolidation or merger of the Company with any other entity
(including, without limitation, a triangular merger) where the stockholders of
the Company immediately prior to the consolidation or merger, would not,
immediately after the consolidation or merger, beneficially own, directly or
indirectly, shares representing fifty percent (50%) of the combined voting power
of all of the outstanding securities of the entity issuing cash or securities in
the consolidation or merger (or its ultimate parent corporation, if any); (iv) a
person, including a "person" as defined in Section 13(d)(3) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), other than the Company or
an employee benefit plan sponsored by the Company, becomes the beneficial owner
(as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of the Company representing forty percent (40%) or more of the total
voting power represented by the Company's then outstanding voting securities,
except for a person who was a beneficial owner of forty percent (40%) or more of
the total voting power of the Company's outstanding voting securities on April
29, 1999; or (v) the Board of Directors of the Company, by a vote of a majority
of all the Directors, adopts a resolution to the effect that a
"Change-in-Control" has occurred for purposes of this Agreement. The term "Good
Reason" shall mean that (i) the Participant's compensation has been materially
reduced, (ii) the Participant's position, duties or responsibilities have been
materially changed, (iii) the Participant, if an employee of the Company, has
been required to move his or her principal residence because his primary place
of employment is moved to a location greater than thirty (30) miles away from
its then current location, (iv) the Company has not paid to the Participant when
due any salary, bonus or other material benefit due to him or her, or (v) there
exists a breach by the Company of any material term or provision of any
employment agreement between it and the Participant, provided, however, that, in
any such event, the Participant shall notify the Company of such event and give
it fifteen (15) days to remedy the situation before terminating his or her
employment.

SECTION 12. NO SPECIAL EMPLOYMENT RIGHTS.
-----------------------------------------

           Nothing contained in the Plan or in any Plan Benefit documentation
shall confer upon any Participant receiving a grant of any Plan Benefit any
right with respect to the continuation of his or her employment by the Company
(or any Related Corporation) or interfere in any way with the right of the
Company (or any Related Corporation), subject to the terms of any separate
employment agreement to the contrary, at any time to terminate such employment
or to increase or decrease the compensation of the Participant from the rate in
existence at the time of the grant of any Plan Benefit. Whether an authorized
leave of absence, or absence in military or government service, shall constitute
termination of employment shall be determined by the Board of Directors.

SECTION 13. AMENDMENT OF THE PLAN.
----------------------------------

           The Board of Directors may at any time and from time to time modify

amendment of the Plan shall not, without the consent of a recipient of any Plan
Benefit, affect his or her rights under any Plan Benefit previously granted.
With the consent of the affected Participant, the Board of Directors may amend
outstanding agreements relating to any Plan Benefit, in a manner not
inconsistent with the Plan. The Board of Directors hereby reserves the right to
amend or modify the terms and provisions of the Plan and of any outstanding
Options to the extent necessary to qualify any or all Options under the Plan for
such favorable federal income tax treatment (including deferral of taxation upon
exercise) as may be afforded incentive stock options under Section 422 of the
Code, provided, however, that the consent of an optionee is required if such
amendment or modification would cause unfavorable income tax treatment for such
optionee.

SECTION 14. WITHHOLDING.
------------------------

           The Company's obligation to deliver shares of stock upon the exercise
of any Option or the granting of an Award or to make payment upon any exercise

Participant of all applicable federal, state and local income and employment tax
withholding requirements.

instruments evidencing such Plan Benefits.
