If a quorum is present and voting, the nominees for director receiving the highest number of votes will be elected as directors.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE NOMINEES LISTED ABOVE. 3

PROPOSAL NUMBER TWO APPROVAL OF AMENDMENT TO THE 1996 AMENDED STOCK OPTION PLAN The board of directors adopted the Extreme Networks 1996 Amended 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 Option Plan currently provides a maximum of 38,028,618 shares of Extreme Networks authorized but unissued or reacquired shares may be issued upon the exercise of options granted under the Option Plan. As of September 30, 2000, approximately 2,377,799 shares remained available for future option grants under the Option Plan. On September 8, 2000, the board of directors amended the Option Plan, subject to stockholder approval, to increase automatically on the first trading day of December of this year and for three years thereafter, the maximum aggregate number of shares of common stock issuable under the plan by that number of shares of common stock equal to 4.9% of the number of shares of common stock issued and outstanding on last trading day of the immediately preceding November. The stockholders are now being asked to approve the establishment of the annual increase in the share reserve. The Company does not believe that the current share reserve is adequate to its needs. In order to provide an adequate reserve of shares which will allow the Company to provide long-term equity incentives under the Option Plan, the Company could seek and receive stockholder approval for annual increases in the share reserve. To effect the routine annual increases in the share reserve, expenses would have to be incurred to obtain the necessary approvals. The board believes that it is in the best interests of the Company and its stockholders to avoid such expenses by amending the Option Plan to automatically increase the share reserve. In addition, the automatic increase proposed here would remove the Option Plan reserve increase from the annual meeting agenda in future years, thereby allowing stockholders to focus on other proposals which are not necessarily routinely approved. Possible disadvantages of the proposed amendment include, but are not limited to, a lack of flexibility in the amount of the annual increase in the share reserve of the Option Plan. Such inflexibility could be remedied by future proposals to revise up or down the automatic increase in the number of shares reserved for any particular year. However, such a remedy would require approval by the stockholders and accordingly, would result in expense for obtaining such approval. The board believes that the advantages of the proposed amendment outweigh the possible disadvantages because the proposed annual increase in the number of shares reserved under the Option Plan would be sufficient in most years, thereby avoiding the expenses involved in obtaining the necessary approvals for routine increases in the Option Plan reserve each year. The board of directors believes that the Company's stock option program is an important factor in attracting and retaining the high caliber employees and consultants essential to the success of the Company in aligning their long-term interests with those of the stockholders. Because competition for highly qualified individuals in the Company's industry is intense, management believes that to successfully attract the best candidates, the Company must offer a competitive stock option program as an essential component of its compensation packages. The board of directors further believes that stock options serve an important role in motivating their holders to contribute to the Company's continued growth and profitability. The proposed amendment is intended to ensure that the Option Plan will continue to have available a reasonable number of shares to meet these needs for the remainder of its term. In addition to the Option Plan, in March 2000 the board approved the Extreme Networks 2000 Nonstatutory Stock Option Plan, also referred to as the Nonstatutory Plan, pursuant to which a maximum of 4,000,000 shares of common stock may be issued. The Nonstatutory Plan provides for the grant of nonstatutory stock options to employees and consultants (excluding officers and directors of Extreme Networks). As of September 30, 2000, options to purchase an aggregate of [____________] shares were outstanding under the Nonstatutory Plan, and [____________] shares remained available for future grants under the Nonstatutory Plan. Summary of the provisions of the Option Plan The following summary of the Option Plan is qualified in its entirety by the specific language of the Option Plan, a copy of which is available to any stockholder upon request. 4

General. The 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 September 30, 2000, Extreme Networks had outstanding options to purchase an aggregate of 19,076,301 shares at a weighted average exercise price of $28.2106. As of September 30, 2000, options to purchase 17,019,830 shares of common stock granted pursuant to the Option Plan had been exercised, and there were 2,377,799 shares of common stock available for future grants under the Option Plan. Shares subject to Plan. Currently, a maximum of 38,028,618 shares of Extreme Networks' authorized but unissued or reacquired common stock may be issued upon the exercise of options granted under the Option Plan. The board of directors has amended the Option Plan, subject to stockholder approval, to automatically increase on the first trading day of December of this year and for three years thereafter, the maximum aggregate number of shares of common stock issuable under the plan by that number of shares of common stock equal to 4.9% of the number of shares of common stock issued and outstanding on the last trading day of the immediately preceding November. In order to comply with the Code, the maximum number of shares which could immediately be issued upon the exercise of ISO's is 38,028,618. 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 Option Plan, the employee grant limit described below and to outstanding options. To the extent any outstanding option under the 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 Option Plan and are available for issuance under the Option Plan. Administration. The 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 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 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 Option Plan also provides, subject to certain limitations, that 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 Option Plan. The board will interpret the 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 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 Option Plan. As of September 30, 2000, Extreme Networks had approximately 792 employees, including nine executive officers and five directors. Any person eligible under the 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 Option Plan, subject to the plan, provides that no employee may be granted options for more than 5,000,000 shares during any fiscal year. Terms and conditions of Options. Each option granted under the 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 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 ISO 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% 5

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 Option Plan will become exercisable and vested at such times as specified by the board. Generally, options granted under the 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 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 such event do not retain direct or indirect beneficial ownership of at least 50% of the total combined voting power of the voting stock of Extreme, its successor, or the corporation to which the assets of Extreme were transferred. 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 Option Plan. To the extent that the options outstanding under the 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 Option Plan at any time, but, without stockholder approval, the board may not amend the 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 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 6

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 exercise date) 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 exercise 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 exercise date. If the optionee is an employee, such ordinary income generally is subject to withholding of income and employment taxes. 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 exercise 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. 7

The board believes that the proposed amendment to the Option Plan to provide for annual increase in the share reserve, 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 PROVIDE FOR ANNUAL INCREASE IN THE SHARE RESERVE. PROPOSAL NUMBER THREE APPROVAL OF AMENDMENT TO THE 1999 EMPLOYEE STOCK PURCHASE PLAN The board of directors adopted the Extreme Networks 1999 Employee Stock Purchase Plan, also referred to as the Stock Purchase Plan, in January 1999, and the shareholders approved the adoption of the Stock Purchase Plan in February 1999. The Stock Purchase Plan permits eligible employees to acquire shares of Extreme's common stock through periodic payroll deductions of up to 15% of total compensation. No more than 1,250 shares may be purchased on any purchase date per employee. Each offering period has a maximum duration of 12 months. The price at which the common stock may be purchased is 85% of the lesser of the fair market value of Extreme's common stock on the first day of the applicable offering period or on the last day of the respective purchase period. A total of 2,000,000 shares of common stock have been reserved for issuance under the Stock Purchase Plan. As of September 30, 2000, 546,680 shares have been issued under the Stock Purchase Plan. Accordingly, there are 1,453,320 shares available for issuance. In September 2000, subject to stockholder approval, the board increased the number of shares authorized for issuance under the Stock Purchase Plan by 2,000,000 shares to a total of 4,000,000 shares. The stockholders are now being asked to approve this amendment. 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 employees to continue to purchase stock under the Stock Purchase Plan. The Board believes that the availability of an opportunity to purchase shares under the Purchase Plan at a discount from market price is important to attracting and retaining qualified employees essential to the success of the Company and is important to provide such persons with incentives to perform in the best interest of the Company. Summary of the provisions of the Stock Purchase Plan The following summary of the Stock Purchase Plan is qualified in its entirety by the specific language of the Stock Purchase Plan, a copy of which is available to any stockholder upon request. General. The Stock Purchase Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code. Each participant in the Stock 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 Stock Purchase Plan prior to such date. Shares subject to Plan. Currently, a maximum of 2,000,000 of Extreme Networks' authorized but unissued or reacquired shares of common stock may be issued under the Stock 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. The board has amended the Stock Purchase Plan, subject to stockholders approval, to increase the share reserve to 4,000,000 shares. 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 Stock Purchase Plan. 8

Administration. The Stock Purchase Plan is administered by the board. Subject to the provisions of the Stock Purchase Plan, the board determines the terms and conditions of purchase rights granted under the Stock Purchase Plan. The board will interpret the Stock 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 Stock Purchase Plan or any purchase rights. The Stock 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 Stock 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 Stock Purchase Plan is eligible to participate in an offering to purchase stock under the Stock 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 Stock 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 Stock Purchase Plan. As of September 30, 2000 approximately 792 employees were eligible to participate in the Stock Purchase Plan. Offerings. Generally, each offering of common stock under the Stock Purchase Plan is for a period of twelve months. Offering periods 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. Each offering period is generally comprised of four three-month purchase periods. 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. Participation and purchase of shares. Participation in the Stock 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 Stock Purchase Plan, that employee will automatically participate in each successive offering period which begins after the final purchase date until such time as that employee withdraws from the Stock Purchase Plan, becomes ineligible to participate in the Stock 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 accrue the right to purchase under the Stock 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 relevant offering period). In addition, no more than 1,250 shares may be purchased by a participant on a purchase date, and no more than an aggregate of 200,000 shares may be purchased by all Stock 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 Stock 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. 9

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 Stock Purchase Plan provides that, in the event of a change in control, the acquiring or successor corporation may assume Extreme Networks' rights and obligations under the Stock 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 Stock 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 Stock 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 Stock 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 Stock Purchase Plan. Summary of federal income tax consequences of the Stock 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 Stock 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 Stock Purchase Plan or purchasing shares of Extreme Networks' common stock under the terms of the Stock Purchase Plan. If a participant disposes of shares purchased under the Stock 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 dispositions, 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 Stock 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 dispositions 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. 10

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. 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 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. The board believes that the proposed amendment to the Stock Purchase Plan to increase the share reserve from 2,000,000 to 4,000,000 is in the best interests of Extreme Networks and its stockholders is discussed above. THEREFORE, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO AMEND THE STOCK PURCHASE PLAN TO INCREASE THE NUMBER OF SHARES RESERVED FOR ISSUANCE UNDER THE PLAN TO 4,000,000. PROPOSAL NUMBER FOUR AMENDMENT OF EXTREME NETWORKS' CERTIFICATE OF INCORPORATION TO INCREASE THE AUTHORIZED NUMBER OF SHARES Extreme Networks' certificate of incorporation currently authorizes the issuance of 150,000,000 shares of common stock, $.001 par value, and 2,000,000 shares of preferred stock, $.001 par value. On September 8, 2000, the board of directors of Extreme Networks adopted a resolution approving an amendment to the certificate of incorporation to increase the authorized number of shares of common stock from 150,000,000 to 750,000,000 and resolved to submit the proposed amendment to the stockholders at the annual meeting. Purpose and Effect of the Amendment The general purpose and effect of the proposed amendment to the certificate of incorporation will be to authorize 600,000,000 additional shares of common stock. The board of directors believes that it is prudent to have the additional shares of common stock available for general corporate purposes, including acquisitions, equity financings, grants of stock options, payment of stock dividends, stock splits or other recapitalizations. Extreme Networks currently has 150,000,000 authorized shares of common stock. As of September 30, 2000, Extreme Networks had 109,925,800 shares issued and outstanding and of the remaining 40,074,200 authorized but unissued shares, has reserved approximately [ ] shares in connection with the possible exercise of outstanding warrants, [ ] shares pursuant to Extreme's option plans and 1,453,320 shares pursuant to Extreme's Stock Purchase Plan. Except in connection with the reserved shares described above, Extreme Networks currently has no arrangements or understandings for the issuance of additional shares of common stock, although opportunities for acquisitions and equity financings could arise at any time. If the board of directors deems it to be in the best interest of Extreme Networks and the stockholders to issue additional shares of common stock in the future, the board of directors generally will not seek further authorization by vote of the stockholders, unless such authorization is otherwise required by law or regulations. The increase in the authorized number of shares of common stock could have an anti-takeover effect. If Extreme Networks' board of directors desired to issue additional shares in the future, such issuance could dilute 11

the voting power of a person seeking control of Extreme Networks, thereby deterring or rendering more difficult a merger, tender offer, proxy contest or an extraordinary corporate transaction opposed by Extreme Networks. Vote required and board of directors recommendation. The affirmative vote of a majority of the issued and outstanding shares of common stock will be required to approve the amendment to the certificate of incorporation increasing the number of authorized shares of common stock from 150,000,000 to 750,000,000. Abstentions and broker non-votes will each be counted as present for purposes of determining the presence of a quorum. Abstention and broker non-votes will have the same effect as a negative vote on this proposal. The board believes that the proposed amendment to the certificate of incorporation 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 FIVE 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, 2001. 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, 2001. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT The following table sets forth certain information, as of September 30, 2000, with respect to the beneficial ownership of Extreme Networks common stock by: . each person known by Extreme Networks to be the beneficial owner of more than 5% of our common stock, . each director and director nominee of Extreme Networks, . the Chief Executive Officer, and the four other highest compensated executive officers of Extreme Networks whose salary and bonus for the year ended July 2, 2000 exceeded $100,000, also referred to as the "Named Executive Officers," and . all executive officers and directors of Extreme Networks as a group. 12

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 Stock Option Plan. Employment contracts and termination of employment and change-in-control arrangements Shares subject to options granted under our 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 directors 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 During the last fiscal year, 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. 17

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, except that a transaction in a statement of change in beneficial ownership for June Hull, Vice President of Human Resources, was not timely filed. 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 2000.

The compensation committee reviews the performance and compensation levels for executive officers and sets salary and bonus levels and option grants under our 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." 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 19

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 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.
