ODD LOTS

As described in Section 1 of the Offer to Purchase, under certain conditions, stockholders holding fewer than 100 shares may have their shares accepted for payment before any proration of other tendered shares. This preference is not available to partial tenders, or to beneficial or record holders of an aggregate of 100 or more shares, even if these holders have separate accounts representing fewer than 100 shares. Accordingly, this section is to be completed only if shares are being tendered by or on behalf of a person owning, beneficially or of record, an aggregate of fewer than 100 shares. The undersigned either (check one box):

¨ is the beneficial or record owner of fewer than 100 shares in the aggregate, all of which are being tendered; or

¨ is a broker, dealer, commercial bank, trust company, or other nominee that (a) is tendering for the beneficial owner(s) shares with respect to which it is the record holder, and (b) believes, based upon representations made to it by the beneficial owner(s), that each such person is the beneficial owner of an aggregate of fewer than 100 shares and is tendering all of such shares.

In addition, the undersigned is tendering shares either (check one box):

¨ at the purchase price, as the same will be determined by Extreme in accordance with the terms of the Offer; or

¨ at the price per share indicated above in the section captioned “Price per Share at which Shares Are Being Tendered.”

CONDITIONAL TENDER

(See Instruction 13)

You may condition your tender of shares on our purchasing a specified minimum number of your tendered shares, all as described in Section 6 of the Offer to Purchase. Unless the minimum number of shares you indicate below is purchased by us in our Offer, none of the shares you tender will be purchased. It is your responsibility to calculate that minimum number of shares that must be purchased if any are purchased, and you are urged to consult your own tax advisor before completing this section. Unless this box has been checked and a minimum number of shares specified, your tender will be deemed unconditional.

¨ The minimum number of shares that must be purchased, if any are purchased, is:                              shares.

If, because of proration, the minimum number of shares that you designated above will not be purchased, we may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, you must have tendered all your shares and checked this box:

Subject to, and effective upon, acceptance for payment of the shares tendered in accordance with the terms and subject to the conditions of the Offer, including, if the Offer is extended or amended, the terms and conditions of the extension or amendment, the undersigned agrees to sell, assign and transfer to, or upon the order of, Extreme all right, title and interest in and to all shares tendered and orders the registration of all shares tendered by book-entry transfer that are purchased under the Offer to or upon the order of Extreme and irrevocably constitutes and appoints the depositary as the true and lawful agent and attorney-in-fact of the undersigned with respect to the shares with full knowledge that the depositary also acts as the agent of Extreme, with full power of substitution (the power of attorney being deemed to be an irrevocable power coupled with an interest), to:

1.    deliver certificate(s) representing the shares or transfer ownership of the shares on the account books maintained by the book-entry transfer facility, together, in either case, with all accompanying evidences of transfer and authenticity, to, or upon the order of, Extreme upon receipt by the depositary, as the undersigned’s agent, of the purchase price with respect to the shares;

2.    present certificates for the shares for cancellation and transfer on Extreme books; and

The undersigned covenants, represents and warrants to Extreme that:

2.    the undersigned understands that tenders of shares pursuant to any one of the procedures described in Section 3 of the Offer to Purchase and in the instructions to this Letter of Transmittal will constitute the undersigned’s acceptance of the terms and conditions of the Offer, including the undersigned’s representation and warranty that (a) the undersigned has a “net long position,” within the meaning of Rule 14e-4 promulgated under the Securities Exchange Act of 1934, in the shares or equivalent securities at least equal to the shares being tendered, and (b) the tender of shares complies with Rule 14e-4;

Extreme will select the lowest purchase price specified by tendering stockholders that will enable Extreme to purchase $100 million worth of shares or, if shares with an aggregate value of less than $100 million are properly tendered at or below the maximum price of $3.70 per share, the highest price at which shares were properly tendered and not properly withdrawn. All shares acquired in the Offer will be acquired at the same purchase price.

Privacy Act Notice.—Section 6109 requires most recipients of dividend, interest, or other payments to give taxpayer identification numbers to payers who must report the payments to IRS. The IRS uses the numbers for identification purposes and may also provide this information to various government agencies for tax enforcement of litigation purposes. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 30% of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties:

1.    Penalty for Failure to Furnish Taxpayer identification Number.—If you fail to furnish your taxpayer identification number to a payer, you are subject to a penalty or $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

2.    Civil Penalty for False Information With Respect to Withholding.—If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

3.    Criminal Penalty for Falsifying Information.—Willfully falsifying certifications or affirmations may be subject to criminal penalties including fines and/or imprisonment.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF OUR OFFER

1.    Guarantee Of Signatures. Depending on how the certificates for your shares are registered and to whom you want deliveries made, you may need to have the signatures on this Letter of Transmittal guaranteed by an eligible guarantor institution. No signature guarantee is required if either:

• this Letter of Transmittal is signed by the registered holder(s) of the shares tendered (which, for these purposes, includes any participant in the book-entry transfer facility whose name appears on a security position listing as the owner of the shares) exactly as the name of the registered holder(s) appears on the certificate(s) for the shares and payment is to be made directly to the holder, unless the holder has completed the box entitled “Special Delivery Instructions” above, in which case, delivery will not be made to the holder; or

• the shares are tendered for the account of a bank, broker, dealer, credit union, savings association or other entity which is a member in good standing of the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity that is also an “eligible guarantor institution,” as that term is defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended, each such entity, referred to as an “eligible guarantor institution.”

In all other cases, including if you have completed the box entitled “Special Delivery Instructions” above, an eligible guarantor institution must guarantee all signatures on this Letter of Transmittal. You may also need to have any certificates you deliver endorsed or accompanied by a stock power, and the signatures on these documents also may need to be guaranteed. See Instruction 6.

2.    Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery Procedures. For your shares to be properly tendered, EITHER (1) OR (2) below must happen:

(1)    The depositary must receive all of the following at its address above in this Letter of Transmittal before or on the date our Offer expires:

• either (a) the certificates for the shares or (b) a confirmation of receipt of the shares pursuant to the procedure for book-entry transfer described in this instruction, and

• either (a) properly completed and executed Letter of Transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) an “agent’s message” of the type described in this Instruction 2 in the case of a book-entry transfer, and

• any other documents required by this Letter of Transmittal.

(2)    You must comply with the guaranteed delivery procedure set forth below.

Book-Entry Delivery. Any institution that is a participant in the book-entry transfer facility’s system may make book-entry delivery of the shares by causing the book-entry transfer facility to transfer shares into the depositary’s account in accordance with the book-entry transfer facility’s procedures for transfer. Delivery of this Letter of Transmittal or any other required documents to the book-entry transfer facility does not constitute delivery to the depositary.

Agent’s Message. The term “agent’s message” means a message transmitted by the book-entry transfer facility to, and received by, the depositary, which states that the book-entry transfer facility has received an express acknowledgment from the participant in the book-entry transfer facility tendering the shares that the participant has received and agrees to be bound by the terms of this Letter of Transmittal and that we may enforce the agreement against them.

Guaranteed Delivery. If you wish to tender your shares but your share certificate(s) are not immediately available or cannot be delivered to the depositary before the Offer expires, the procedure for book-entry transfer

14

cannot be completed on a timely basis, or if time will not permit all required documents to reach the depositary before the Offer expires, your shares may still be tendered, if all of the following conditions are satisfied:

• the tender is made by or through an eligible guarantor institution;

• the depositary receives by hand, mail, overnight courier or facsimile transmission, before the expiration date, a properly completed and duly executed notice of guaranteed delivery in the form provided with this Letter of Transmittal, specifying the price at which shares are being tendered, including (where required) a signature guarantee by an eligible guarantor institution in the form set forth in the notice of guaranteed delivery; and

• all of the following are received by the depositary within three NASDAQ Global Market trading days after the date of receipt by the depositary of the notice of guaranteed delivery:

• either (a) the certificates for the shares or (b) a confirmation of receipt of the shares pursuant to the procedure for book-entry transfer described in this instruction 2;

• either (a) a properly completed and executed Letter of Transmittal or a manually executed facsimile of it, including any required signature guarantees, or (b) an “agent’s message” of the type described in this Instruction 2 in the case of a book-entry transfer; and

• any other documents required by this Letter of Transmittal.

The method of delivering all documents, including share certificates, this Letter of Transmittal and any other required documents, is at your election and risk. If delivery is by mail, we recommend you use registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to ensure timely delivery.

Except as specifically permitted by Section 6 of the Offer to Purchase, we will not accept any alternative, conditional or contingent tenders, nor will we purchase any fractional shares, except as expressly provided in the Offer to Purchase. All tendering stockholders, by execution of this Letter of Transmittal or a manually signed facsimile of this Letter of Transmittal, waive any right to receive any notice of the acceptance of their tender.

3.    Inadequate Space. If the space provided in the box entitled “Description of Shares Tendered” above is inadequate, the certificate numbers and/or the number of shares should be listed on a separate signed schedule and attached to this Letter of Transmittal.

4.    Partial Tenders and Unpurchased Shares. (This paragraph does not apply to stockholders who tender by book-entry transfer.) If fewer than all of the shares evidenced by any certificate are to be tendered, fill in the number of shares that are to be tendered in the column entitled “Number of Shares Tendered” in the box entitled “Description of Shares Tendered” above. In that case, if any tendered shares are purchased, a new certificate for the remainder of the shares (including any shares not purchased) evidenced by the old certificate(s) will be issued and sent to the registered holder(s), unless otherwise specified in the box entitled “Special Delivery Instructions” in this Letter of Transmittal, as soon as practicable after the expiration date. Unless otherwise indicated, all shares represented by the certificate(s) set forth above and delivered to the depositary will be deemed to have been tendered.

If any tendered shares are not purchased or are properly withdrawn, or if fewer than all shares evidenced by a stockholder’s certificates are tendered, certificates for unpurchased shares will be returned as soon as practicable after the expiration or termination of the Offer or the proper withdrawal of the shares, as applicable. In the case of shares tendered by book-entry transfer at the book-entry transfer facility, the shares will be credited to the appropriate account maintained by the tendering stockholder at the book-entry transfer facility. In each case, shares will be returned or credited without expense to the stockholder.

5.    Indication of Price at Which Shares are Being Tendered. If you want to tender your shares, you must properly complete the pricing section of this Letter of Transmittal, which is called “Price at Which You Are

15

Tendering.” You must check one box in the pricing section. If more than one box is checked or no box is checked, your shares will not be properly tendered. If you want to tender portions of your shares at more than one price, you must complete a separate Letter of Transmittal for each price at which you tender shares. However, the same shares cannot be tendered at more than one price, unless previously and properly withdrawn as provided in Section 4 of the Offer to Purchase.

6.    Signatures on Letter of Transmittal; Stock Powers and Endorsements; Exact Signature. If this Letter of Transmittal is signed by the registered holder(s) of the shares tendered, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate(s) without any change whatsoever.

Joint Holders. If the shares tendered are registered in the names of two or more joint holders, each holder must sign this Letter of Transmittal.

Different Names on Certificates. If any tendered shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate letters of transmittal (or manually signed facsimiles) as there are different registrations of certificates.

Endorsements. When this Letter of Transmittal is signed by the registered holder(s) of the shares tendered, no endorsements of certificates representing the shares or separate stock powers are required.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the certificates listed, the certificates must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appears on the certificates, and the signatures on the certificates or stock powers must be guaranteed by an eligible institution. See Instruction 1.

Signatures of Fiduciaries. If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or any other person acting in a fiduciary or representative capacity, that person should so indicate when signing and must submit proper evidence satisfactory to us of his or her authority to so act.

7.    Stock Transfer Taxes. Except as provided in this Instruction 7, no stock transfer tax stamps or funds to cover tax stamps need accompany this Letter of Transmittal. We will pay any stock transfer taxes payable on the transfer to us of shares purchased pursuant to our Offer. If, however,

• payment of the purchase price is to be made to any person other than the registered holder(s);

• shares not tendered or rejected for purchase are to be registered in the name(s) of any person(s) other than the registered holder(s); or

• certificates representing tendered shares are registered in the name(s) of any person(s) other than the person(s) signing this Letter of Transmittal,

then the depositary will deduct from the purchase price the amount of any stock transfer taxes (whether imposed on the registered holder(s), other person(s) or otherwise) payable on account of the transfer to that person, unless satisfactory evidence of the payment of the taxes or any exemption therefrom is submitted.

8.    Special Delivery Instructions. If the certificates and/or checks are to be sent to someone other than the person signing this Letter of Transmittal or to the signer at a different address, the box entitled “Special Delivery Instructions” on this Letter of Transmittal should be completed as applicable and signatures must be guaranteed as described in Instruction 1.

9.    Irregularities. All questions as to the number of shares to be accepted, the price to be paid for shares to be accepted and the validity, form, eligibility, including time of receipt, and acceptance for payment of any tender of shares will be determined by us in our sole discretion. Our determination will be final and binding on

16

all parties. We reserve the absolute right to reject any or all tenders of any shares that we determine are not in proper form or the acceptance of or payment for which we determine may be unlawful. We also reserve the absolute right to waive any of the conditions of the Offer or any defect or irregularity in any tender with respect to any particular shares or any particular stockholder. Our interpretation of the terms of the Offer (including these instructions) will be final and binding on all parties. No tender of shares will be deemed to have been properly made until all defects or irregularities have been cured by the tendering stockholder or waived by us. Unless waived, any defects and irregularities in connection with tenders must be cured within the time period, if any, we determine. None of us, the depositary, the information agent, the dealer manager or any other person will be under any duty to give notice of any defects or irregularities in any tender, or incur any liability for failure to give any notice.

10.    Questions and Requests for Assistance and Additional Copies. Questions and requests for additional copies of the Offer to Purchase, this Letter of Transmittal or the notice of guaranteed delivery may be directed to the information agent at the telephone number and address set forth on the back page of each of the Offer to Purchase and this Letter of Transmittal.

11.    Federal Income Tax Withholding. To prevent backup federal income tax withholding equal to 30% of the gross payments payable pursuant to the Offer, each tendering stockholder who is not a foreign stockholder (as defined below) and who does not otherwise establish an exemption from backup withholding must notify the depositary of the stockholder’s correct taxpayer identification number (employer identification number or social security number), or certify that that taxpayer is awaiting a taxpayer identification number, and provide various other information by completing, under penalties of perjury, the Substitute Form W-9 included in this Letter of Transmittal. If a stockholder properly certifies that such stockholder is awaiting a taxpayer identification number, 30% of any payment during the 60-day period following the date of the Substitute Form W-9 will be retained by the depositary and, if the stockholder properly furnishes his or her taxpayer identification number within that 60-day period, the depositary will remit the amount retained to such stockholder and will not withhold amounts from future payments under the backup withholding rules. If the stockholder does not properly furnish his or her taxpayer identification number within that 60-day period, the amount retained will be remitted to the IRS as backup withholding and backup withholding will apply to future payments. Foreign stockholders should generally complete and sign an appropriate Form W-8 to avoid backup withholding.

The depositary will withhold United States federal income taxes equal to 30% of the gross payments payable to a foreign stockholder unless the depositary and we determine that an exemption is available. For example, an applicable income tax treaty may reduce or eliminate such tax, in which event a foreign stockholder claiming a reduction in or exemption from such tax under the applicable income tax treaty provides through the third party withholding agent a properly completed IRS Form W-8BEN (or suitable successor form claiming the benefit of the applicable tax treaty). Alternatively, an exemption applies if the gain is effectively connected with a U.S. trade or business of the foreign stockholder and the foreign stockholder provides an appropriate statement to that effect on a properly completed IRS Form W-8ECI (or suitable successor or substitute form). For this purpose, a “foreign stockholder” is any stockholder that is not:

• a citizen or resident of the United States;

• a corporation, partnership, or other entity created or organized in or under the laws of the United States, any State or any political subdivision thereof;

• an estate, the income of which is subject to United States federal income taxation regardless of the source of the income; or

• a trust whose administration is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all of its substantial decisions.

17

To comply with IRS Circular 230, you are hereby notified that: (a) any discussion of federal tax issues contained or referred to herein is not intended or written to be used, and cannot be used by you, for the purposes of avoiding penalties that may be imposed on you under the Internal Revenue Code; (b) such discussion is written to support the promotion or marketing of the Offer addressed by the written advice herein; and (c) you should seek advice based on your particular circumstances from an independent tax advisor.

12.    Lost, Stolen, Destroyed or Mutilated Certificates. If your certificate for part or all of your shares has been lost, stolen, misplaced or destroyed, you should contact Mellon Investor Services LLC, the transfer agent for our shares, at (800) 522-6645 (toll-free), for instructions as to obtaining an affidavit of loss. The affidavit of loss will then be required to be submitted together with this Letter of Transmittal in order to receive payment for shares that are tendered and accepted for payment. A bond may be required to be posted by you to secure against the risk that the certificates may be subsequently recirculated. You are urged to contact Mellon Investor Services LLC immediately in order to receive further instructions, to permit timely processing of this documentation and for a determination as to whether you will need to post a bond.

13.    Conditional Tenders. As described in Section 6 of the Offer to Purchase, you may tender shares subject to the condition that all or a specified minimum number of your shares tendered pursuant to this Letter of Transmittal or a notice of guaranteed delivery must be purchased if any shares tendered are purchased.

If you wish to make a conditional tender, you must indicate this in the box captioned “Conditional Tender” in this Letter of Transmittal or, if applicable, the notice of guaranteed delivery. In the box captioned “Conditional Tender” in this Letter of Transmittal or the notice of guaranteed delivery, you must calculate and appropriately indicate the minimum number of shares that must be purchased if any are to be purchased.

As discussed in Section 6 of the Offer to Purchase, proration may affect whether we accept conditional tenders and may result in shares tendered pursuant to a conditional tender being deemed withdrawn if the minimum number of shares would not be purchased. If, because of proration, the minimum number of shares that you designate will not be purchased, we may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, you must have tendered all your shares and check the box so indicating. Upon selection by lot, if any, we will limit our purchase in each case to the designated minimum number of shares.

All tendered shares will be deemed unconditionally tendered unless the “Conditional Tender” box is completed.

The conditional tender alternative is made available so that a stockholder may seek to structure our purchase of shares in our Offer from the stockholder in a manner that the sale will be treated as a sale of those shares by the stockholder, rather than the payment of a dividend to the stockholder, for federal income tax purposes. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased from the stockholder in order for the stockholder to qualify for sale rather than dividend treatment.

14.    Equity Compensation Plans. If you hold vested but unexercised options, you must exercise such options in accordance with the terms of the applicable stock option or compensation plans and tender the shares received upon such exercise in accordance with the Offer. You must exercise your vested options at least five business days prior to the expiration date of the Offer (which, unless the Offer is extended, will require you to exercise such options no later than 5:00 p.m., New York time, on September 5, 2008) in order to provide you with sufficient time to properly tender the shares in the Offer. In no event are any stock options to be delivered to the depositary in connection with a tender of shares hereunder. An exercise of a stock option cannot be revoked even if all or a portion of the shares received upon the exercise or conversion and tendered in the Offer are not purchased in the Offer for any reason.
