     The accompanying proxy is solicited by the board of directors of Extreme
Networks, Inc., a Delaware corporation, for use at the annual meeting of

                              GENERAL INFORMATION

     Annual report.  An annual report for the fiscal year ended June 30, 1999 is
enclosed with this proxy statement.

     Voting securities.  Only stockholders of record as of the close of business
on September 30, 1999 will be entitled to vote at the meeting and any
adjournment thereof.  As of that date, there were 49,719,168 shares of our
common stock, par value $0.001 per share, issued and outstanding.  Stockholders
may vote in person or by proxy.  Each holder of shares of common stock is
entitled to one (1) vote for each share of stock held on the proposals presented
in this proxy statement.  Our Bylaws provide that a majority of all of the
shares of stock entitled to vote, whether present in person or represented by
proxy, shall constitute a quorum for the transaction of business at the meeting.

     Solicitation of proxies.  We will bear the cost of soliciting proxies.  In
addition, we will solicit stockholders by mail through our regular employees.
We will request banks and brokers and other custodians, nominees and fiduciaries
to solicit their customers who own our common stock and will reimburse them for
their reasonable, out-of-pocket costs.  We may use the services of our officers,
directors and others to solicit proxies, personally or by telephone, without
additional compensation.

     Voting of proxies.  All valid proxies received prior to the meeting will be
voted.  All shares represented by a proxy will be voted, and where a stockholder
specifies by means of the proxy a choice with respect to any matter to be acted
upon, the shares will be voted in accordance with the specification so made.  If
no choice is indicated on the proxy, the shares will be voted in favor of the
proposal.  A stockholder giving a proxy has the power to revoke his or her
proxy, at any time prior to the time it is voted, by delivery to the Secretary
of Extreme Networks of a written instrument revoking the proxy or a duly
executed proxy with a later date, or by attending the meeting and voting in
person.

                             PROPOSAL NUMBER ONE
                            ELECTION OF DIRECTORS

     We have a classified board of directors currently consisting of one class I
director, two class II directors and two class III directors, who will serve
until the annual meetings of stockholders to be held in 1999, 2000 and 2001,
respectively, and until their respective successors are duly elected and
qualified.  At each annual meeting of stockholders, directors are elected for a
term of three years to succeed those directors whose terms expire on the annual
meeting dates.

     The nominee for election at the 1999 annual meeting to class I of the board
of directors is Gordon L. Stitt.  If elected, Mr. Stitt will serve as director
until the annual meeting in 2002 and until his respective successor is elected
and qualified or until his earlier resignation or removal.  If a nominee
declines to serve or becomes unavailable for any reason, or if a vacancy occurs
before the election, although management knows of no reason to anticipate that
this will occur, the proxies may be voted for such substitute nominee as
management may designate.

     If a quorum is present and voting, the nominees for director receiving the
highest number of votes will be elected as directors.  Abstentions and shares
held by brokers that are present, but not voted because the brokers were
prohibited from exercising discretionary authority; i.e., "broker non-votes,"
will be counted as present in determining if a quorum is present.

     The table below sets forth, for Extreme Networks' directors, including the
Class I nominee to be elected at the meeting, certain information with respect
to their age and background.

                              PROPOSAL NUMBER TWO
          APPROVAL OF AMENDMENT TO THE AMENDED 1996 STOCK OPTION PLAN


     The board of directors adopted the Extreme Networks 1996 Stock Option Plan,
also referred to as the Option Plan, in September, 1996 and the shareholders
approved the adoption of the 1996 Option Plan on the same date.

     The Internal Revenue Code of 1986 (the "Code") limits the amount of
compensation paid to a corporation's chief executive officer and four other most
highly compensated officers that the corporation may deduct as an expense for
federal income tax purposes. To enable Extreme Networks to continue to deduct in
full all amounts of ordinary income recognized by its executive officers in
connection with options granted under the 1996 Option Plan, the board of
directors has amended the 1996 Option Plan, subject to stockholder approval, to
limit to 2,500,000 the maximum number of shares for which options may be granted
to any employee in any fiscal year. However, Extreme Networks' stock option
grants typically do not approach this limit.

     The stockholders are now being asked to approve the establishment of the
grant limit. The board of directors believes that approval of this amendment is
in the best interests of Extreme Networks and our stockholders because it will
allow Extreme Networks to continue to deduct compensation related to options
granted under the Option Plan for federal income tax purposes.

Summary of the provisions of the 1996 Option Plan

     The following summary of the 1996 Option Plan is qualified in its entirety
by the specific language of the 1996 Option Plan, a copy of which is available
to any stockholder upon request.

     General.  The 1996 Option Plan provides for the grant of "incentive stock
options" ("ISOs") within the meaning of Section 422 of the Code and for
nonstatutory stock options.  As of June 30, 1999, Extreme Networks had
outstanding options to purchase an aggregate of 4,878,767 shares at a weighted
average exercise price of $6.08. As of June 30, 1999, options to purchase
6,702,325 shares of Common Stock granted pursuant to the 1996 Option Plan had
been exercised, and there were 5,433,217 shares of Common Stock available for
future grants under the 1996 Option Plan.

     Shares subject to Plan.  Currently, a maximum of 17,014,309 shares of
Extreme Networks' authorized but unissued or reacquired common stock may be
issued upon the exercise of options granted pursuant to the 1996 Option Plan.
In the event of any stock dividend, stock split, reverse stock split,
recapitalization, combination, reclassification, or similar change in the
capital structure of Extreme Networks, appropriate adjustments will be made to
the shares subject to the 1996 Option Plan, the proposed employee grant limit
described above and to outstanding options.  To the extent any outstanding
option under the 1996 Option Plan expires or terminates prior to exercise in
full or if shares issued upon exercise of an option are repurchased by Extreme
Networks, the shares of common stock for which such option is not exercised or
the repurchased shares are returned to the 1996 Option Plan and will again be
available for issuance under the 1996 Option Plan.

     Administration.  The 1996 Option Plan is administered by the board of
directors or a duly appointed committee of the board.  With respect to the
participation of individuals whose transactions in Extreme Networks' equity
securities are subject to Section 16 of the Securities Exchange Act of 1934, the
1996 Option Plan will be administered in compliance with the requirements, if
any, of Rule 16b-3 under the Exchange Act.  Subject to the provisions of the
1996 Option Plan, the board determines the persons to whom options are to be
granted, the number of shares to be covered by each option, whether an option is
to be an ISO or a nonstatutory stock option, the terms of vesting and
exercisability of each option, including the effect thereon of an optionee's
termination of service, the type of consideration to be paid to Extreme Networks
upon exercise of an option, the duration of each option, and all other terms and
conditions of the options.  The 1996 Option Plan also provides, subject to
certain limitations, that 

                                       4

<PAGE>
 
Extreme Networks' will indemnify any director, officer or employee against all
reasonable expenses, including attorneys' fees, incurred in connection with any
legal action arising from such person's action or failure to act in
administering the 1996 Option Plan. The board will interpret the 1996 Option
Plan and options granted thereunder, and all determinations of the board will be
final and binding on all persons having an interest in the 1996 Option Plan or
any option.

     Eligibility.  Generally, all employees, directors and consultants of
Extreme Networks or of any present or future parent or subsidiary corporations
of Extreme Networks are eligible to participate in the 1996 Option Plan.  As of
June 30, 1999, Extreme Networks had approximately 250 employees, including six
executive officers and five directors.  Any person eligible under the 1996
Option Plan may be granted a nonstatutory stock option.  However, only employees
may be granted ISOs.  In order to preserve Extreme Networks' ability to deduct
compensation related to options granted under the 1996 Option Plan, the board
has amended the 1996 Option Plan, subject to stockholder approval, to provide
that no employee may be granted options for more than 2,500,000 shares during
any fiscal year.

     Terms and conditions of Options.  Each option granted under the 1996 Option
Plan is evidenced by a written agreement between Extreme Networks and the
optionee specifying the number of shares subject to the option and the other
terms and conditions of the option, consistent with the requirements of the 1996
Option Plan.  The exercise price per share must equal at least the fair market
value of a share of Extreme Networks' Common Stock on the date of grant of an
ISO and at least 85% of the fair market value of a share of the Common Stock on
the date of grant of a nonstatutory stock option.  The exercise price of any 150
granted to a person who at the time of grant owns stock possessing more than 10%
of the total combined voting power of all classes of stock of Extreme Networks
or any parent or subsidiary corporation of Extreme Networks (a "10%
Stockholder") must be at least 110% of the fair market value of a share of
Extreme Networks' common stock on the date of grant.  The fair market value of
Extreme Networks' common stock is based on the trading price of Extreme
Networks' shares on the Nasdaq National Market.

     Generally, the exercise price may be paid in cash, by check or by tender of
shares of Extreme Networks' common stock owned by the optionee having a fair
market value not less than the exercise price, by the assignment of the proceeds
of a sale or a loan with respect to some or all of the shares of common stock
being acquired upon the exercise of the option, by means of a promissory note,
by any lawful method approved by the board or by any combination of these.  The
board may nevertheless restrict the forms of payment permitted in connection
with any option grant.

     Options granted under the 1996 Option Plan will become exercisable and
vested at such times as specified by the board.  Generally, options granted
under the 1996 Option Plan vest in installments, subject to the optionee's
continued employment or service over a period of four (4) years.  The maximum
term of an option granted under the 1996 Option Plan is ten years, except that
an ISO granted to a 10% Stockholder may not have a term longer than five years.
Options are nontransferable by the optionee other than by will or by the laws of
descent and distribution and are exercisable during the optionee's lifetime only
by the optionee.

     Change in control.  The Option Plan provides that a "change in control"
occurs in the event of:

     .  a sale or exchange by the stockholders of more than 50% of Extreme's
        voting stock,

     .  a merger or consolidation involving Extreme,

     .  the sale, exchange or transfer of all or substantially all of the assets
        of Extreme, or

     .  a liquidation or dissolution of Extreme,

wherein, upon any such event, the stockholders of Extreme immediately before

     Upon a change in control, the board may arrange for the acquiring or
successor corporation to assume or substitute new options for the options
outstanding under the 1996 Option Plan.  To the extent that the options
outstanding under the 1996 Option Plan are not assumed, substituted for, or
exercised prior to such event, they will terminate. Notwithstanding the
foregoing, upon a change in control, options granted to executive officers of
Extreme Networks partially accelerate without regard to assumption or
replacement by any successor corporation.

     Termination or Amendment.  Unless sooner terminated, no options may be
granted under the Option Plan after September 3, 2006.  The board of directors
may terminate or amend the 1996 Option Plan at any time, but, without
stockholder approval, the board may not amend the 1996 Option Plan to increase
the total number of shares of common stock reserved for issuance thereunder,
change the class of persons eligible to receive ISOs, or adopt any other
amendment which would require shareholder approval under any applicable law,
regulation or rule.  No amendment may adversely affect an outstanding option
without the consent of the optionee, unless the amendment is required to
preserve the option's status as an ISO or is necessary to comply with any
applicable law.

Summary of federal income tax consequences of the Option Plan

     The following summary is intended only as a general guide as to the United
States federal income tax consequences under current law of participation in the
1996 Option Plan and does not attempt to describe all possible federal or other
tax consequences of such participation or tax consequences based on particular
circumstances.

     ISOs.  An optionee recognizes no taxable income for regular income tax
purposes as the result of the grant or exercise of an ISO.  Optionees who do not
dispose of their shares for two years following the date the option was granted
or within one year following the exercise of the option will normally recognize
a long-term capital gain or loss equal to the difference, if any, between the
sale price and the purchase price of the shares.  If an optionee satisfies both
such holding periods upon a sale of the shares, Extreme Networks will not be
entitled to any deduction for federal income tax purposes.  If an optionee
disposes of shares either within two years after the date of grant or within one
year from the date of exercise referred to as a disqualifying disposition, the
difference between the fair market value of the shares on the determination date
(as discussed under "Nonstatutory stock options" below) and the option exercise
price (not to exceed the gain realized on the sale if the disposition is a
transaction with respect to which a loss, if sustained, would be recognized)
will be taxed as ordinary income at the time of disposition.  Any gain in excess
of that amount will be a capital gain.  If a loss is recognized, there will be
no ordinary income, and such loss will be a capital loss.  A capital gain or
loss will be long-term if the optionee's holding period is more than 12 months.
Any ordinary income recognized by the optionee upon the disqualifying
disposition of the shares generally should be deductible by Extreme Networks for
federal income tax purposes, except to the extent such deduction is limited by
applicable provisions of the Code or the regulations thereunder.

     The difference between the option exercise price and the fair market value
of the shares on the determination date of an ISO is an adjustment in computing
the optionee's alternative minimum taxable income and may be subject to an
alternative minimum tax which is paid if such tax exceeds the regular tax for
the year.  Special rules may apply with respect to certain subsequent sales of
the shares in a disqualifying disposition, certain basis adjustments for
purposes of computing the alternative minimum taxable income on a subsequent
sale of the shares and certain tax credits which may arise with respect to
optionees subject to the alternative minimum tax.

     Nonstatutory stock options.  Options not designated or qualifying as ISOs
will be nonstatutory stock options.  Nonstatutory stock options have no special
tax status.  An optionee generally does not recognize taxable income as the
result of the grant of such an option.  Upon exercise of a nonstatutory stock
option, the optionee normally recognizes ordinary income in an amount equal to
the difference between the option exercise price and the fair market value of
the shares on the determination date (as defined below).  If the optionee is an
employee, such ordinary income generally is subject to withholding of income and
employment taxes.  The determination date is the date on which the option is
exercised unless the shares are subject to a substantial risk of forfeiture and
are not transferable, in which case the determination date is the earlier of (i)
the date on which the shares are transferable or (ii) the date on which the
shares are not subject to a substantial risk of forfeiture.  If the
determination date is after the exercise date, the optionee may elect, pursuant
to Section 83(b) of the Code, to have the exercise date be the 

                                       6

<PAGE>
 
determination date by filing an election with the Internal Revenue Service not
later than 30 days after the date the option is exercised. Upon the sale of
stock acquired by the exercise of a nonstatutory stock option, any gain or loss,
based on the difference between the sale price and the fair market value on the
determination date, will be taxed as capital gain or loss. A capital gain or
loss will be long-term if the optionee's holding period is more than 12 months.
Extreme Networks generally should be entitled to a deduction equal to the amount
of ordinary income recognized by the optionee as a result of the exercise of a
nonstatutory stock option, except to the extent such deduction is limited by
applicable provisions of the Code or the regulations thereunder. No tax
deduction is available to Extreme Networks with respect to the grant of a
nonstatutory stock option or the sale of the stock acquired pursuant to such
grant.

Vote required and board of directors recommendation

     The affirmative vote of a majority of the shares present or represented by
proxy and entitled to vote at the annual meeting of stockholders at which a
quorum representing a majority of all outstanding shares of our common stock is
present and voting, either in person or by proxy, is required for approval of
this proposal.  Abstentions and broker non-votes each will be counted as present
for purposes of determining the presence of a quorum.  Abstentions will have the
same effect as a negative vote on this proposal.  Broker non-votes will have no
effect on the outcome of this vote.

     The board believes that the proposed amendment to the Option Plan to
approve the grant limit of 2,500,000 shares per employee per fiscal year, as
described above, is in the best interests of Extreme and the stockholders for
the reasons stated above.  THEREFORE, THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS A VOTE "FOR" THE PROPOSAL TO AMEND THE OPTION PLAN TO APPROVE THE
GRANT LIMIT OF 2,500,000 SHARES PER EMPLOYEE PER FISCAL YEAR.

                             PROPOSAL NUMBER THREE
                  APPROVAL OF A CERTAIN ANTI-TAKEOVER MEASURE

General

     The Board of Directors has unanimously approved the inclusion in of a
certain provision available to public companies under Delaware law that defers
hostile take-over attempts in Extreme Networks' Amended and Restated Certificate
of Incorporation and the Bylaws, as more particularly described below.

     In considering the proposal, stockholders should be aware that the overall
effect of the proposed provision is to make it more difficult for holders of a
majority of the outstanding shares of Common Stock to change the composition of
the Board of Directors and to remove existing management in circumstances where
a majority of the stockholders may be dissatisfied with the performance of the
incumbent directors or otherwise desire to make changes. This provision, if
included in Extreme Networks' charter documents, could make a proxy contest a
less effective means of removing or replacing existing directors or could make
it more difficult to make a change in control of Extreme Networks which is
opposed by the Board of Directors. This strengthened tenure and authority of the
Board of Directors could enable the Board of Directors to resist change and
otherwise thwart the desires of a majority of the stockholders. Because this
provision may have the effect of continuing the tenure of the current Board of
Directors, the Board has recognized that the individual directors have a
personal interest in this provision that may differ from those of the
stockholders. However, the Board believes that this provision's primary purpose
is to ensure that the Board will have sufficient time to consider fully any
proposed takeover attempt in light of the short and long-term benefits and other
opportunities available to Extreme Networks and, to the extent the Board
determines to proceed with the takeover, to effectively negotiate terms that
would maximize the benefits to Extreme Networks and its stockholders.

     A hostile takeover attempt may have a positive or a negative effect on
Extreme Networks and its stockholders, depending on the circumstances
surrounding a particular takeover attempt. Takeover attempts that have not been
negotiated or approved by the board of directors of a corporation can seriously
disrupt the business and management of a corporation and generally present to
the stockholders the risk of terms which may be less than favorable to all of
the stockholders than would be available in a Board-approved transaction. Board-
approved transactions may be carefully planned and undertaken at an opportune
time in order to obtain maximum value for the corporation and all of its
stockholders with due consideration to matters such as the recognition or
postponement of gain or loss for tax purposes, the management and business of
the acquiring corporation and maximum strategic deployment of corporate assets.
In addition, in the case of a proposal which is presented to the Board of
Directors, there is a greater opportunity for the Board to analyze the proposal
thoroughly, to develop and evaluate alternatives, to negotiate for improved
terms and to present its recommendations to the stockholders in the most
effective manner.

     The Board of Directors recognizes that hostile takeover attempts do not
always have the unfavorable consequences or effects described above and may
frequently be beneficial to stockholders, providing all stockholders with
considerable value for their shares. However, the Board of Directors believes
that the potential disadvantages of unapproved takeover attempts are
sufficiently great such that prudent steps to reduce the likelihood of such
takeover attempts are in the best interests of Extreme Networks and its
stockholders. Accordingly, the Board has proposed a certain measure for
inclusion in the Certificate of Incorporation or the Bylaws that may have the
effect of discouraging or deterring hostile takeover attempts.

     Notwithstanding the belief of the Board as to the benefits to stockholders
of the changes, stockholders should recognize that one of the effects of such
changes may be to discourage a future attempt to acquire control of Extreme
Networks which is not presented to and approved by the Board of Directors, but
which a substantial number, and perhaps even a majority, of the Extreme
Networks' stockholders might believe to be in their best 

                                       8

<PAGE>
 
interests or in which stockholders might receive a substantial premium for their
shares over the current market price. As a result, stockholders who might desire
to participate in such a transaction may not have an opportunity to do so.

     In addition, by increasing the probability that any person or group seeking
control of Extreme Networks would be forced to negotiate directly with the Board
of Directors, the proposed takeover defenses could discourage takeover bids by
means of a hostile tender offer, proxy contest or otherwise without the approval
of the Board.  Thus, the principal disadvantages to the stockholders which
result from discouraging such hostile takeover bids would be to (i) reduce the
likelihood that any acquiror would make a hostile tender offer for the
outstanding shares of stock of Extreme Networks at a premium over the market
rate and (ii) increase the difficulty of removing the existing Board of
Directors and management even if, in a particular case, removal would be
beneficial to stockholders generally.

     It should be noted, however, that the Board of Directors has a fiduciary
duty to the stockholders to negotiate for the best interests of the stockholders
and not for its own interests.  Further, while the proposed takeover defenses
may discourage hostile takeover attempts, this provision would not prevent a
hostile acquisition of Extreme Networks.

     The Board of Directors has considered the potential disadvantages and
believes that the potential benefits of the provisions described below outweigh
the possible disadvantages. In particular, the Board believes that the benefits
associated with enabling the Board to fully consider and negotiate proposed
takeover attempts make this proposal beneficial to Extreme Networks and its
stockholders.

Limitation on ability to call special meetings

     Under our present charter documents, special meetings of stockholders may
be called by the Board of Directors, the holders of 10% or more of the
outstanding voting power and such other persons as may be designated in the
Certificate of Incorporation or Bylaws of the Company.

     Delaware law, however, provides that special meetings of stockholders may
only be called by the Board or by any other person as may be designated in the
Certificate of Incorporation or Bylaws.  The Board of Directors has proposed a
provision in the Certificate of Incorporation and the Bylaws providing that
special meetings of stockholders may be called only by the Board of Directors.
Such a provision precludes a stockholder from mounting a proxy contest or taking
action to amend charter documents until the next annual meeting.  Such a
provision could have the affect of deterring efforts to seek control of Extreme
Networks on a basis which some stockholders might deem favorable.

     In the event this proposal is not approved by the requisite vote of the
stockholders, the Bylaws will provide that special meetings of stockholders may
be called by the Board of Directors or the holders of 10% or more of the
outstanding voting power.  In the event this proposal is approved, the
Certificate of Incorporation and Bylaws will provide that special meetings of
stockholders may be called only by the Board of Directors as set forth in
Exhibit 1 and 2.

Vote required and board of directions recommendation

     The affirmative vote of a majority of the voting power of all outstanding
Common Stock of Extreme Networks is required for approval of this proposal.

     The Board believes that the proposed provisions regarding the limitation on
the ability to call special meetings by the stockholders under the Certificate
of Incorporation and Bylaws is in the best interest of the stockholders and
Extreme Networks for the reasons stated above.  THEREFORE, THE BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" APPROVAL OF THIS PROPOSAL.

                             PROPOSAL NUMBER FOUR
              RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

     The board of directors has appointed Ernst & Young LLP to serve as
independent auditors to audit the financial statements of Extreme for the fiscal
year ending July 1, 2000. Ernst & Young LLP has acted in such capacity since its
appointment for fiscal year ended June 1997.  A representative of Ernst & Young
LLP will be present at the annual meeting of stockholders, will be given the
opportunity to make a statement if the representative desires and will be
available to respond to appropriate questions.

     In the event that ratification by the stockholders of the appointment of
Ernst & Young LLP as our independent auditors is not obtained, the board of
directors will reconsider said appointment.

     The affirmative vote of a majority of the shares present or represented by
proxy and entitled to vote at the annual meeting of stockholders, at which a
quorum representing a majority of all outstanding shares of our common stock is
present and voting, either in person or by proxy, is required for approval of
this proposal.  Abstentions and broker non-votes will each be counted as present
for purposes of determining the presence of a quorum.  Abstentions will have the
same effect as a negative vote on this proposal.  Broker non-votes will have no
effect on the outcome of the vote on this proposal.

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" RATIFICATION OF
ERNST & YOUNG LLP AS EXTREME'S INDEPENDENT ACCOUNTANTS FOR THE FISCAL YEAR
ENDING JULY 1, 2000.

Compensation of directors

     Directors are entitled to reimbursement of all reasonable out-of-pocket
expenses incurred in connection with their attendance at board and board
committee meetings.  All directors are eligible to receive options to purchase
our common stock under our 1996 Stock Option Plan.

Employment contracts and termination of employment and change-in-control
arrangements

     Shares subject to options granted under our Amended 1996 Stock Option Plan
will generally vest over four years, with 25% of the shares vesting after one
year and the remaining shares vesting in equal monthly increments over the
following 36 months. The options and stock purchase agreements granted to our
executive officers and our outside director provide for accelerated vesting of
the shares in the event of a "transfer of control," as defined in the option or
stock purchase agreement, of Extreme.

     This form of agreement provides that if, as of the date of the transfer of
control, less than 75% of the total option shares are vested, the number of
vested shares will be increased, as of the date of the transfer of control, to
the lesser of 75% of the total option shares, or the sum of the number of vested
shares, which are determined under the standard vesting schedule, plus 50% of
the unvested shares, which are determined under the standard vesting schedule.
After the transfer of control, the remaining unvested shares will vest in equal
monthly increments over the longer of 50% of the period beginning on the date of
the transfer of control and ending on the date four years after the option grant
date or 12 months.

Compensation committee interlocks and insider participation in compensation
decisions

     The compensation committee is composed of Messrs. Carinalli and Wolken.  No
interlocking relationships exist between any member of our compensation
committee and any member of any other company's board of directors or
compensation committee.  The compensation committee makes recommendations
regarding our employee stock plans and makes decisions concerning salaries and
bonus compensation for executive officers of Extreme Networks.

Certain relationships and related transactions

     Since June 1998, there has not been, nor is there currently proposed, any
transaction or series of similar transactions to which Extreme Networks was or
is to be a party in which the amount involved exceeds $60,000, and in which any
director, executive officer or holder of more than 5% any class of voting
securities of Extreme Networks and members of that person's immediate family had
or will have a direct or indirect material interest other than the transactions
described below.

     In January 1999, the board of directors approved a loan to Vito E. Palermo,
our Chief Financial Officer, of $75,000 at an interest rate of 4.51% per annum.
The loan is due in January 2003 but we may forgive this loan if our Chief
Executive Officer determines, in his sole discretion, that we have attained
financial and administrative objectives. In addition, in connection with Mr.
Palermo's employment, we have agreed to pay him nine months of severance if we
terminate him without cause within the first twelve months of his employment.

     In January 1999, Extreme Networks entered into indemnification agreements
with each of the directors and executive officers. Such indemnification
agreements require Extreme Networks to indemnify these individuals to the
fullest extent permitted by law.

Section 16(a) beneficial ownership reporting compliance

     Section 16(a) of the Securities Exchange Act of 1934 requires Extreme
Networks' executive officers, directors and persons who beneficially own more
than 10% of our common stock to file initial reports of ownership and reports of
changes in ownership with the Securities and Exchange Commission.  These persons
are required by SEC regulations to furnish Extreme Networks with copies of all
Section 16(a) forms that they file.

                                       16

<PAGE>
 
     Based solely on our review of the forms furnished to us and written
representations from certain reporting persons, we believe that all filing
requirements applicable to our executive officers, directors and persons who
beneficially own more than 10% of our common stock were complied with in fiscal
1999, except that one transaction on a statement of change in beneficial
ownership for each of Promod Haque and Norwest Equity Partners V was not timely
filed.

     The following table sets forth grants of stock options under the 1996
Option Plan during fiscal 1999 by:

     .  the Named Executive Officers;

     .  all current executive officers as a group;

     .  all current directors who are not executive officers as a group; and

     .  all employees, who are not executive officers, as a group.

        REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

     The compensation committee is comprised of two outside directors of the
board of directors and is responsible for setting and monitoring policies
governing compensation of executive officers.  The compensation committee
reviews the performance and compensation levels for executive officers and sets
salary and bonus levels and option grants under our 1996 Stock Option Plan.  The
objectives of the committee are to correlate executive compensation with our
business objectives and performance, and to enable us to attract, retain and
reward executive officers who contribute to our long-term success.

Salary

     The compensation committee annually assesses the performance and sets the
salary of the President and Chief Executive Officer, Gordon L. Stitt.  In turn,
Mr. Stitt annually assesses the performance of all other executive officers and
recommends salary increases which are reviewed and approved by the compensation
committee.

     In particular, Mr. Stitt's compensation as President and Chief Executive
Officer is based on compensation levels of President/Chief Executive Officers of
comparable size companies.  In addition, the compensation committee considers
certain incentive objectives based on Extreme Networks' performance as it
relates to revenue levels and earnings per share levels.

     In determining executive officer salaries, the compensation committee
reviews recommendations from Mr. Stitt which include information from salary
surveys, performance evaluations and the financial condition of Extreme
Networks.  The compensation committee also establishes both financial and
operational based objectives and goals in determining executive officer
salaries.  These goals and objectives include sales and spending forecasts for
the upcoming year and published executive compensation literature for comparable
sized companies.

     For more information regarding the compensation and employment arrangements
of Mr. Stitt and other executive officers, see "EXECUTIVE COMPENSATION AND OTHER
MATTERS--Compensation of executive officers and employment contracts and
termination of employment and change-in-control arrangements."

Bonuses

     The compensation committee administers a bonus plan to provide additional
incentives to executives who meet established performance goals.  In
consultation with the Chief Executive Officer, the compensation committee
annually determines the total amount of cash bonuses available for executive
officers and certain other management employees.  In fiscal 1999, awards under
this bonus plan were contingent upon Extreme Networks' attainment of revenue and
operating profit targets, set by the compensation committee in consultation with
the Chief Executive Officer.  The target amount of the bonus for the Chief
Executive Officer and more senior executive officers was set by the compensation
committee; the amounts of individual bonuses for the remaining executive
officers and other management were proposed by the Chief Executive Officer,
subject to approval by the compensation committee.  Awards are weighted so that
proportionately higher awards are received when Extreme Networks' performance
reaches maximum targets, proportionately smaller awards are received when the
performance reaches minimum targets and no awards are received when we do not
meet minimum performance targets.

Stock Options

     The compensation committee believes that employee equity ownership provides
significant motivation to executive officers to maximize value for our
stockholders and, therefore, periodically grants stock options under our stock
option plan.  Stock options are granted at the current market price and will
only have value if our stock price increases over the exercise price.

     The compensation committee determines the size and frequency of option
grants for executive officers, after consideration of recommendations from the
Chief Executive Officer.  Recommendations for options are based 

                                       18

<PAGE>
 
upon the relative position and responsibilities of each executive officer,
previous and expected contributions of each officer to Extreme Networks and
previous option grants to such executive officers. Generally, option grants vest
25% twelve months after commencement of employment or after the date of grant
and continue to vest thereafter in equal monthly installments over three years,
conditioned upon continued employment.

                  DESCRIPTION OF OTHER EMPLOYEE BENEFIT PLANS

                       1999 EMPLOYEE STOCK PURCHASE PLAN

     The following is a brief summary of the Extreme Networks 1999 Employee
Stock Purchase Plan, also referred to as the Purchase Plan.

Summary of the provisions of the Purchase Plan

     The following summary of the Purchase Plan is qualified in its entirety by
the specific language of the Purchase Plan, a copy of which is available to any
stockholder upon request.

     General.  The Purchase Plan is intended to qualify as an "employee stock
purchase plan" under Section 423 of the Code.  Each participant in the Purchase
Plan is granted at the beginning of each offering under the plan the right to
purchase through accumulated payroll deductions up to a number of shares of the
common stock of Extreme Networks determined on the first day of the offering.
The purchase right is automatically exercised on the last day of each purchase
period within the offering unless the participant has withdrawn from the
Purchase Plan prior to such date.

     Shares subject to Plan.  A maximum of 1,000,000 of Extreme Networks'
authorized but unissued or reacquired shares of common stock may be issued under
the Purchase Plan, subject to appropriate adjustment in the event of a stock
dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in Extreme Networks' capital structure or in
the event of any merger, sale of assets or other reorganization of Extreme
Networks.  If any purchase right expires or terminates, the shares subject to
the unexercised portion of such purchase right will again be available for
issuance under the Purchase Plan.

     Administration.  The Purchase Plan is administered by the board.  Subject
to the provisions of the Purchase Plan, the board determines the terms and
conditions of purchase rights granted under the Purchase Plan.  The board will
interpret the Purchase Plan and purchase rights granted thereunder, and all
determinations of the board will be final and binding on all persons having an
interest in the Purchase Plan or any purchase rights.  The Purchase Plan
provides, subject to certain limitations, that Extreme Networks will indemnify
any director, officer or employee against all reasonable expenses, including
attorney's fees, incurred in connection with any legal action arising from such
person's action or failure to act in administering the Purchase Plan.

     Eligibility.  Any employee of Extreme Networks or of any present or future
parent or subsidiary corporation of Extreme Networks designated by the board for
inclusion in the Purchase Plan is eligible to participate in an offering to
purchase stock under the Purchase Plan so long as the employee is customarily
employed for at least 20 hours per week and 5 months per calendar year.
However, no employee who owns or holds stock options to purchase, or as a result
of participation in the Purchase Plan would own or hold options to purchase,
five percent or more of the total combined voting power or value of all classes
of stock of Extreme Networks or of any parent or subsidiary corporation of
Extreme Networks is entitled to participate in the Purchase Plan.

     Offerings.  Generally, each offering of common stock under the Purchase
Plan is for a period of twelve months.  Offering Periods will generally commence
on the first day of February, May, August and November of each year and end on
the last day of the following January, April, July and October, respectively.
However, the first offering period commenced on April 9, 1999 and will end on
April 30, 2000.  Each offering period will generally be comprised of four three-
month purchase periods, although the first purchase period of the first offering
period commenced on April 9, 1999 and ended on July 31, 1999.  Shares are
purchased on the last day of each purchase period.  The board may establish a
different term for one or more offerings or purchase periods or different
commencement or ending dates for an offering or a purchase period.

                                       21

<PAGE>
 
     Participation and purchase of shares.  Participation in the Purchase Plan
is limited to eligible employees who authorize payroll deductions prior to the
start of an offering period.  Payroll deductions may not exceed 15% (or such
other rate as the board determines) of an employee's compensation for any pay
period during the offering period.  Once an employee becomes a participant in
the Purchase Plan, that employee will automatically participate in each
successive offering period until such time as that employee withdraws from the
Purchase Plan, becomes ineligible to participate in the Purchase Plan, or
terminates employment.

     Subject to certain limitations, each participant in an offering has a
purchase right equal to the number of whole shares determined by dividing the
participant's aggregate payroll deduction by the applicable purchase price for
the purchase period.  During any calendar year, no participant may purchase
under the Purchase Plan shares of Extreme Networks' common stock having a fair
market value exceeding $25,000 (measured by the fair market value of Extreme
Networks' common stock on the first day of the offering period in which the
shares are purchased). In addition, no more than 625 shares may be purchased by
a participant on a purchase date, and no more than an aggregate of 100,000
shares may be purchased by all Purchase Plan participants on a given purchase
date.

     At the end of each purchase period, Extreme Networks issues to each
participant in the offering the number of shares of Extreme Networks' Common
Stock determined by dividing the amount of payroll deductions accumulated for
the participant during that purchase period by the purchase price, subject to
the limitations set forth above.  The price per share at which shares are sold
generally equals 85% of the lesser of the fair market value per share of Extreme
Networks' common stock on the first day of the offering period or the purchase
date.  The fair market value of the common stock on any relevant date generally
will be the closing price per share on such date as reported on the Nasdaq
National Market.  Any payroll deductions under the Purchase Plan not applied to
the purchase of shares will be returned to the participant, unless the amount
remaining is less than the amount necessary to purchase a whole share of common
stock, in which case the remaining amount may be applied to the next purchase
period or offering period.

     A participant may withdraw from an offering at any time without affecting
his eligibility to participate in future offerings.  However, once a participant
withdraws from an offering, that participant may not again participate in the
same offering.

     Change in control.  The Purchase Plan provides that, in the event of a
change of control, the acquiring or successor corporation may assume Extreme
Networks' rights and obligations under the Purchase Plan or substitute
substantially equivalent purchase rights for such corporation's stock.  If the
acquiring or successor corporation elects not to assume or substitute for the
outstanding purchase rights, the board of directors may accelerate the last day
of the offering period to a date on or before the date of the change in control.
Any purchase rights that are not assumed, substituted for, or exercised prior to
the change in control will terminate.

     Termination or amendment.  The Purchase Plan will continue until terminated
by the Board or until all of the shares reserved for issuance have been issued.
The board may at any time amend or terminate the Purchase Plan, except that the
approval of Extreme Networks' stockholders is required within twelve months of
the adoption of any amendment increasing the number of shares authorized for
issuance under the Purchase Plan, or changing the definition of the corporations
which may be designated by the board as corporations the employees of which may
participate in the Purchase Plan.

Summary of federal income tax consequences of the Purchase Plan

     The following summary is intended only as a general guide as to the United
States federal income tax consequences under current law of participation in the
Purchase Plan and does not attempt to describe all possible federal or other tax
consequences of such participation or tax consequences based on particular
circumstances.

     A participant recognizes no taxable income either as a result of commencing
participation in the Purchase Plan or purchasing shares of Extreme Networks'
common stock under the terms of the Purchase Plan.

                                       22

<PAGE>
 
     If a participant disposes of shares purchased under the Purchase Plan
within either two years from the first day of the applicable offering period or
within one year from the purchase date, known as disqualifying disposition), the
participant will realize ordinary income in the year of such disposition equal
to the amount by which the fair market value of the shares on the purchase date
exceeds the purchase price.  The amount of the ordinary income will be added to
the participant's basis in the shares, and any additional gain or resulting loss
recognized on the disposition of the shares will be a capital gain or loss,
which will be long-term if the participant's holding period is more than twelve
months.

     If the participant disposes of shares purchased under the Purchase Plan at
least two years after the first day of the applicable offering period and at
least one year after the purchase date, the participant will realize ordinary
income in the year of disposition equal to the lesser of (i) the excess of the
fair market value of the shares on the date of disposition over the purchase
price or (ii) 15% of the fair market value of the shares on the first day of the
applicable offering period.  The amount of any ordinary income will be added to
the participant's basis in the shares, and any additional gain recognized upon
the disposition after such basis adjustment will be a long-term capital gain.
If the fair market value of the shares on the date of disposition is less than
the purchase price, there will be no ordinary income and any loss recognized
will be a long-term capital loss.

     If the participant still owns the shares at the time of death, the lesser
of (i) the excess of the fair market value of the shares on the date of death
over the purchase price or (ii) 15% of the fair market value of the shares on
the first day of the offering period in which the shares were purchased will
constitute ordinary income in the year of death.

     Extreme Networks should be entitled to a deduction in the year of a
disqualifying disposition equal to the amount of ordinary income recognized by
the participant as a result of the disposition, except to the extent such
deduction is limited by applicable provisions of the Code or the regulations
thereunder.  In all other cases, no deduction is allowed to Extreme Networks.

                                      OF

Incorporation.

     4.   This Restated Certificate of Incorporation restates and integrates the
Certificate of Incorporation of this corporation as herein set forth in full:

     FIRST:  The name of the corporation is Extreme Networks, Inc. (hereinafter
     -----                                                                     
sometimes referred to as the "Corporation").

     SECOND:  The address of the registered office of the Corporation in the
     ------                                                                 
State of Delaware is Incorporating Services, Ltd., 15 East North Street, in the

     THIRD:  The purpose of the Corporation is to engage in any lawful act or
     -----                                                                   
activity for which a corporation may be organized under the General Corporation
Law of Delaware.

     FOURTH:  The Corporation is authorized to issue two classes of stock to be
     ------                                                                    
designated, respectively, "Preferred Stock" and "Common Stock."  The total
number of shares of Preferred Stock the Corporation shall have authority to
issue is 2,000,000, $0.001 par value per share, and the total number of shares
of Common Stock the Corporation shall have authority to issue is 150,000,000,
$0.001 par value per share. The shares of Preferred Stock shall initially be
undesignated and may be issued from time to time in one or more additional
series.

     The Board of Directors is hereby authorized, within the limitations and
restrictions stated herein, to determine or alter the rights, preferences,
privileges and restrictions granted to or imposed upon a wholly unissued series
of Preferred Stock, and the number of shares constituting any such series and
the designation thereof, or any of them; and to increase or decrease the number
of shares constituting any such series and the designation thereof, or any of
them; and to increase or decrease the number of shares of any series subsequent

<PAGE>
 
series, but, in respect of decreases, not below the number of shares of such
series then outstanding. In case the number of shares of any series should be so
decrease, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolutions originally fixing the number
of shares of such series.

     FIFTH:  The following provisions are inserted for the management of the
     -----                                                                  
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

     1.   The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors.  In addition to the powers and
authority expressly conferred upon them by statute or by this Certificate of
Incorporation or the Bylaws of the Corporation, the directors are hereby
empowered to exercise all such powers and do all such acts and things as may be
exercised or done by the Corporation.

     2.   The directors of the Corporation need not be elected by written
ballot unless the Bylaws so provide.

     3.   On and after the closing date of the first sale of the Corporation's
Common Stock pursuant to a firmly underwritten registered public offering which
results in the automatic conversion of the Corporation's Preferred Stock (the
"IPO"), any action required or permitted to be taken by the stockholders of the
Corporation must be effected at a duly called annual or special meeting of
stockholders of the Corporation and may not be effected by any consent in
writing by such stockholders.  Prior to such sale, unless otherwise provided by
law, any action which may otherwise be taken at any meeting of the stockholders
may be taken without a meeting and without prior notice, if a written consent
describing such actions is signed by the holders of outstanding shares having
not less than the minimum number of votes which would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.

     4.   Special meetings of stockholders of the Corporation may be called only
by the Board of Directors pursuant to a resolution adopted by a majority of the
total number of authorized directors (whether or not there exist any vacancies
in previously authorized directorships at the time any such resolution is
presented to the Board for adoption).

     SIXTH:
     ----- 

     1.   The number of directors shall initially be set at five (5) and,
thereafter, shall be fixed from time to time exclusively by the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board for adoption).  Upon the closing of the IPO, the directors shall be
divided into three classes with the term of office of the first class (Class I)
to expire at the first annual meeting of the stockholders following the IPO; the
term of office of the second class (Class II) to expire at the second annual
meeting of stockholders held following the IPO; the term of office of the third
class (Class III) to expire at the third annual meeting of stockholders; and
thereafter for each such term to expire at each third succeeding annual meeting
of stockholders after such election.  Subject to the rights of the holders of
any series of Preferred Stock then outstanding, a vacancy resulting from the
removal of a director by the stockholders as provided in Section 3 below may be
filled at a 

                                       2

<PAGE>
 
special meeting of the stockholders held for that purpose. All directors shall
hold office until the expiration of the term for which elected, and until their
respective successors are elected, except in the case of the death, resignation,
or removal of any director.

     2.   Subject to the rights of the holders of any series of Preferred Stock
then outstanding, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation or other cause (other than removal from office
by a vote of the stockholders) may be filled only by a majority vote of the
directors then in office, though less than a quorum, and directors so chosen
shall hold office for a term expiring at the next annual meeting of stockholders
at which the term of office of the class to which they have been elected
expires, and until their respective successors are elected, except in the case
of the death, resignation, or removal of any director.  No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any incumbent director.

     3.   Subject to the rights of the holders of any series of Preferred Stock
then outstanding, any directors, or the entire Board of Directors, may be
removed from office at any time, with or without cause, but only by the
affirmative vote of the holders of at least a majority of the voting power of
all of the then outstanding shares of capital stock of the Corporation entitled
to vote generally in the election of directors, voting together as a single
class.  Vacancies in the Board of Directors resulting from such removal may be
filled by a majority of the directors then in office, though less than a quorum,
or by the stockholders as provided in Section 1 above.  Directors so chosen
shall hold office for a term expiring at the next annual meeting of stockholders

repeal Bylaws of the Corporation.  Any adoption, amendment or repeal of Bylaws

the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involved intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived an

     If the Delaware General Corporation Law is hereafter amended to authorize
the further elimination or limitation of the liability of a director, then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the Delaware General Corporation Law, as so amended.

     Any repeal or modification of the foregoing provisions of this Article
EIGHTH by the stockholders of the Corporation shall not adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification.

     NINTH:  The Corporation reserves the right to amend or repeal any provision
     -----                                                                      
contained in this Certificate of Incorporation in the manner prescribed by the
laws of the State of Delaware and all rights conferred upon stockholders are

any other provision of this Certificate of Incorporation or any provision of law
which might otherwise permit a lesser vote or no vote, but in addition to any
vote of the holders of any class or series of the stock of this Corporation
required by law or by this Certificate of Incorporation, the affirmative vote of
the holders of at least 66-2/3% of the voting power of all of the then
outstanding shares of the capital stock of the Corporation entitled to vote
generally in the election of directors, voting together as a single class, shall
be required to amend or repeal this Article NINTH, Article FIFTH, Article SIXTH,
Article SEVENTH or Article EIGHTH.

Directors shall each year fix, which date shall be within thirteen months
subsequent to the later of the date of incorporation or the last annual meeting

only by the Board of Directors pursuant to a resolution adopted by a majority of
the total number of authorized directors (whether or not there exists any
vacancies in previously authorized directorships at the time any such resolution
is presented to the Board of Directors for adoption) and shall be held at such
place, on such date, and at such time as they shall fix. Business transacted at
special meetings shall be confined to the purpose or purposes stated in the

     Section 1.3    Notice of Meetings.  Written notice of the place, date, and
                    ------------------

are announced at the meeting at which the adjournment is taken; provided,
however, that if the date of any adjourned meeting is more than thirty (30) days

the President, or in the absence of such designation any Vice President, or in
the absence of the President or any Vice President, a chairman chosen by the
majority of the voting shares represented in person or by proxy, shall act as

accordance therewith or, at the Chairman's discretion, it may be conducted
otherwise in accordance with the wishes of the stockholders in attendance.  The
date and time of the opening and closing of the polls for each matter upon which
the stockholders will vote at the meeting shall be announced at the meeting.

     The Chairman shall also conduct the meeting in an orderly manner, rule on
the precedence of and procedure on, motions and other procedural matters, and
exercise discretion with respect to such procedural matters with fairness and
good faith toward all those entitled to take part.  The Chairman may impose
reasonable limits on the amount of time taken up at the meeting on discussion in
general or on remarks by any one stockholder.  Should any person in attendance
become unruly or obstruct the meeting proceedings, the Chairman shall have the
power to have such person removed from participation.  Notwithstanding anything
in the Bylaws to the contrary, no business shall be conducted at a meeting
except in accordance with the procedures set forth in this Section 1.6 and

the Corporation. To be timely, a stockholder proposal to be presented at an
annual meeting shall be received at the Corporation's principal executive
offices not less than 120 calendar days in advance of the date that the
Corporation's (or the Corporation's predecessor's) proxy statement was released
to stockholders in connection with the previous year's annual meeting of
stockholders, except that if no annual meeting was held in the previous year or
the date of the annual meeting has been changed by more than 30 calendar days

or in the event of a special meeting, notice by the stockholder to be timely
must be received not later than the close of business on the tenth day following

vote which is registered in his or her name on the record date for the meeting,
except as otherwise provided herein or required by law.

     All voting, including on the election of directors but excepting where
otherwise required by law, may be by a voice vote; provided, however, that upon
demand therefor by a stockholder entitled to vote or his or her proxy, a stock
vote shall be taken.  Every stock vote 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.
Every vote taken by ballots shall be counted by an inspector or inspectors
appointed by the chairman of the meeting.

     The stock list shall also be kept at the place of the meeting during the
whole time thereof and shall be open to the examination of any such stockholder
who is present.  This list shall presumptively determine the identity of the
stockholders entitled to vote at the meeting and the number of shares held by
each of them.

from office by a vote of the stockholders) may be filled only by a majority vote
of the directors then in office, though less than a quorum, and directors so
chosen shall hold office for a term expiring at the next annual meeting of
stockholders. No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

only by the affirmative vote of the holders of at least a majority of the voting
power of all of the then outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors, voting together as a
single class.  Vacancies in the Board of Directors resulting from such removal

quorum, or by the stockholders as 

                                       4

<PAGE>
 
provided in Article II, Section 2.1 above. Directors so chosen shall hold office

Directors shall be held at such place or places, on such date or dates, and at
such time or times as shall have been established by the Board of Directors and
publicized among all directors. A notice of each regular meeting shall not be

of holders of any class or series of Preferred Stock then outstanding,
nominations for the election of Directors may be made by the Board of Directors
or a proxy committee appointed by the Board of Directors or by any stockholder
entitled to vote in the election of Directors generally. However, any
stockholder entitled to vote in the election of Directors generally may nominate
one or more persons for election as Directors at a meeting only if timely notice
of such stockholder's intent to make such nomination or nominations has been
given in writing to the Secretary of the Corporation. To be timely, a
stockholder nomination for a director to be elected at an annual meeting shall
be received at the Corporation's principal executive offices not less than 120
calendar days in advance of the date that the Corporation's (or the
Corporation's Predecessor's) Proxy statement was released to stockholders in
connection with the previous year's annual meeting of stockholders, except that
if no annual meeting was held in the previous year or the date of the annual
meeting has been changed by more than 30 calendar days from the date
contemplated at the time of the previous year's proxy statement, or in the event
of a nomination for director to be elected at a special meeting, notice by the
stockholders to be timely must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
special meeting was mailed or such public disclosure was made. Each such notice
shall set forth: (a) the name and address of the stockholder who intends to make
the nomination and of the person or persons to be nominated; (b) a
representation that the

                                       6

<PAGE>
 
stockholder is a holder of record of stock of the Corporation entitled to vote
for the election of Directors on the date of such notice and intends to appear
in person or by proxy at the meeting to nominate the person or persons specified
in the notice; (c) a description of all arrangements or understandings between
the stockholder and each nominee and any other person or persons (naming such
person or persons) pursuant to which the nomination or nominations are to be
made by the stockholder; (d) such other information regarding each nominee
proposed by such stockholder as would be required to be included in a proxy
statement filed pursuant to the proxy rules of the Securities and Exchange
Commission, had the nominee been nominated, or intended to be nominated, by the
Board of Directors; and (e) the consent of each nominee to serve as a director
of the Corporation if so elected.

     In the event that a person is validly designated as a nominee in accordance
with this Section 2.11 and shall thereafter become unable or unwilling to stand
for election to the Board of Directors, the Board of Directors or the
stockholder who proposed such nominee, as the case may be, may designate a
substitute nominee upon delivery, not fewer than five days prior to the date of
the meeting for the election of such nominee, of a written notice to the
Secretary setting forth such information regarding such substitute nominee as
would have been required to be delivered to the Secretary pursuant to this
Section 2.11 had such substitute nominee been initially proposed as a nominee.
Such notice shall include a signed consent to serve as a director of the
Corporation, if elected, of each such substitute nominee.

     If the chairman of the meeting for the election of Directors determines
that a nomination of any candidate for election as a Director at such meeting
was not made in accordance with the applicable provisions of this Section 2.11,
such nomination shall be void; provided, however, that nothing in this Section
2.11 shall be deemed to limit any voting rights upon the occurrence of dividend
arrearages provided to holders of Preferred Stock pursuant to the Preferred
Stock designation for any series of Preferred Stock.

harmless by the Corporation to the fullest extent authorized by Delaware Law, as
the same exists or may hereafter be amended (but, in the case of any such

undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it should be determined ultimately that such director or officer
is not entitled to be indemnified under this Section or otherwise.

     Section 8.2    Right of Claimant to Bring Suit.  If a claim under Section 
                    -------------------------------                   
8.1 of this Article VIII is not paid in full by the Corporation within ninety
(90) days after a written claim has been received by the Corporation, the
claimant may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim and, if such suit is not frivolous or
brought in bad faith, the claimant shall be entitled to be paid also the expense
of prosecuting such claim. The burden of proving such claim shall be on the
claimant. It shall be a defense to any such action (other then an action brought
to enforce a claim for expenses incurred in defending any proceeding in advance
of its final disposition where the required undertaking, if any, has been
tendered to this Corporation) that the claimant has not met the standards of
conduct which make it permissible under the Delaware General Corporation Law for
the Corporation to indemnify the claimant for the amount claimed. Neither the
failure of the Corporation (including its Board of Directors, independent legal
counsel, or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the Corporation (including its Board of Directors, independent legal counsel,
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

Certificate of Incorporation, bylaw, agreement, vote of stockholders or

extent reasonably available, at its expense, to protect itself and any such
director, officer, employee or agent of the Corporation or another corporation,
partnership, joint venture, trust or other enterprise against any such expense,
liability or loss, whether or not the Corporation would have the power to
indemnify such person against such expense, liability or loss under the Delaware
General Corporation Law.

     Section 8.6    Effect of Amendment.  Any amendment, repeal or modification 
                    -------------------                               
of any provision of this Article VIII by the stockholders and the directors of
the Corporation shall not adversely affect any right or protection of a director

modification.
