Letter of Transmittal

The Instructions set forth in this Letter of Transmittal should be read carefully before this Letter of Transmittal is completed.

This Letter of Transmittal is to be used either if certificates for shares (as defined below) are to be forwarded herewith or, unless an Agent’s Message (as defined in Section 3 of the Offer to Purchase (as defined below)) is utilized, if delivery of shares is to be made by book-entry transfer to an account maintained by the Depositary (as defined below) at the Book-Entry Transfer Facility (as defined in Section 3 of the Offer to Purchase) pursuant to the procedures set forth in Section 3 of the Offer to Purchase. Tendering stockholders whose certificates for shares are not immediately available or who cannot deliver either the certificates for, or a book-entry confirmation (as defined in Section 3 of the Offer to Purchase) with respect to, their shares and all other documents required hereby to the Depositary by the Expiration Time (as defined in the Offer to Purchase) must tender their shares in accordance with the guaranteed delivery procedures set forth in Section 3 of the Offer to Purchase. See Instruction 2. Capitalized terms used but not defined in this Letter of Transmittal have the meaning ascribed to them in the Offer to Purchase.

DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

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):

A tendering stockholder may condition his or her tender of shares upon the Company purchasing a specified minimum number of the shares tendered, all as described in Section 6 of the Offer to Purchase. Unless at least the minimum number of shares you indicate below is purchased by the Company pursuant to the terms of the Tender Offer, none of the shares tendered by you will be purchased. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased if any are purchased, and each stockholder is urged to consult his or her own tax advisor before completing this section. Unless this box has been checked and a minimum specified, your tender will be deemed unconditional:

If, because of proration, the minimum number of shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, the tendering stockholder must have tendered all of his or her shares and checked this box:

The undersigned hereby tenders to CME Group Inc. (the “Company”) the above-described shares of Class A Common Stock, par value $0.01 per share, including the associated preferred stock purchase rights (the “shares”), of the Company, on the terms and subject to the conditions set forth in the Company’s Offer to Purchase, dated August 1, 2007 (the “Offer to Purchase”), and this Letter of Transmittal (which, together with any amendments or supplements thereto or hereto, collectively constitute the “Tender Offer”), receipt of which is hereby acknowledged. Unless the context otherwise requires, all references to the shares shall refer to the Class A common stock of the Company (including the associated preferred stock purchase rights).

Subject to and effective on acceptance for payment of, and payment for, the shares tendered with this Letter of Transmittal in accordance with the terms and subject to the conditions of the Tender Offer, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company all right, title and interest in and to all the shares that are being tendered hereby and irrevocably constitutes and appoints Computershare Trust Company, N.A. (the “Depositary”) the true and lawful agent and attorney-in-fact of the undersigned, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to the full extent of the undersigned’s rights with respect to such shares to (a) deliver certificates for such shares or transfer ownership of such shares on the account books maintained by the Book-Entry Transfer Facility, together, in any such case, with all accompanying evidences of transfer and authenticity to, or upon the order of, the Company, (b) present such shares for cancellation and transfer on the Company’s books and (c) receive all benefits and otherwise exercise all rights of beneficial ownership of such shares, all in accordance with the terms and subject to the conditions of the Tender Offer.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the shares tendered hereby and that, when the same are accepted for purchase by the Company, the Company will acquire good title thereto, free and clear of all security interests, liens, restrictions, claims and encumbrances, and the same will not be subject to any adverse claim or right. The undersigned will, on request by the Depositary or the Company, execute and deliver any additional documents deemed by the Depositary or the Company to be necessary or desirable to complete the sale, assignment and transfer of the shares tendered hereby, all in accordance with the terms of the Tender Offer.

All authority conferred or agreed to be conferred pursuant to this Letter of Transmittal shall be binding on the successors, assigns, heirs, personal representatives, executors, administrators and other legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. Except as stated in the Offer to Purchase and this Letter of Transmittal, this tender is irrevocable.

The valid tender of shares pursuant to any of the procedures described in Section 3 of the Offer to Purchase and in the instructions to this Letter of Transmittal will constitute a binding agreement between the undersigned and the Company on the terms and subject to the conditions of the Tender Offer.

It is a violation of Rule 14e-4 promulgated under the Exchange Act (as defined in the Offer to Purchase) for a person acting alone or in concert with others, directly or indirectly, to tender shares for such person’s own account unless at the time of tender and at the expiration of the Tender Offer such person has a “net long position” in (a) the shares that is equal to or greater than the amount tendered and will deliver or cause to be delivered such shares for the purpose of tender to the Company within the period specified in the Tender Offer or (b) other securities immediately convertible into, exercisable for or exchangeable into shares (“Equivalent Securities”) that is equal to or greater than the amount tendered and, upon the acceptance of such tender, will acquire such shares by conversion, exchange or exercise of such Equivalent Securities to the extent required by the terms of the Tender Offer and will deliver or cause to be delivered such shares so acquired for the purpose of tender to the Company within the period specified in the Tender Offer. Rule 14e-4 also provides a similar restriction applicable to the tender or guarantee of a tender on behalf of another person. A tender of shares made pursuant to any method of delivery set forth in this Letter of Transmittal will constitute the undersigned’s representation and warranty to the Company that (a) the undersigned has a “net long position” in shares or

Equivalent Securities being tendered within the meaning of Rule 14e-4, and (b) such tender of shares complies with Rule 14e-4.

The undersigned understands that all shares properly tendered and not properly withdrawn will be purchased at the purchase price, without interest, upon the terms and subject to the conditions of the Tender Offer, including its proration provisions (including the “odd lot” priority provisions) and conditional tender provisions, and that the Company will return at its expense all other shares, including shares not purchased because of proration or conditional tenders, promptly following the Expiration Time.

Unless otherwise indicated herein under “Special Payment Instructions,” please issue the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment in the name(s) of the registered holder(s) appearing under “Description of Shares Tendered.” Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment (and accompanying documents, as appropriate) to the address(es) of the registered holder(s) appearing under “Description of Shares Tendered.” In the event that both the “Special Delivery Instructions” and the “Special Payment Instructions” are completed, please issue the check for payment of the purchase price and/or return any certificates for shares not tendered or accepted for payment (and any accompanying documents, as appropriate) in the name(s) of, and deliver such check and/or return such certificates (and any accompanying documents, as appropriate) to, the person or persons so indicated. Please credit any shares tendered herewith by book-entry transfer that are not accepted for payment by crediting the account at the Book-Entry Transfer Facility designated above. The undersigned recognizes that the Company has no obligation pursuant to the “Special Payment Instructions” to transfer any shares from the name of the registered holder(s) thereof if the Company does not accept for payment any of the shares so tendered.

1. Guarantee of Signatures. No signature guarantee is required on this Letter of Transmittal if either (a) this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Instruction 1, includes any participant in the Book-Entry Transfer Facility’s system whose name appears on a security position listing as the owner of the shares) of shares tendered herewith, unless such registered holder(s) has completed either the box entitled “Special Payment Instructions” or the box entitled “Special Delivery Instructions” on this Letter of Transmittal or (b) such shares are tendered for the account of a financial institution that is a member in good standing of the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program (any such financial institution, an “eligible institution”). In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an eligible institution. Stockholders may also need to have any certificates they deliver endorsed or accompanied by a stock power, and the signatures on these documents also may need to be guaranteed. See Instruction 5.

2. Requirements of Tender. This Letter of Transmittal is to be completed by stockholders either if certificates are to be forwarded herewith or, unless an Agent’s Message is utilized, if delivery of shares is to be made pursuant to the procedures for book-entry transfer set forth in Section 3 of the Offer to Purchase. For a stockholder properly to tender shares pursuant to the Tender Offer, either (a) a Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, together with any required signature guarantees, or, in the case of a book-entry transfer, an Agent’s Message, and any other required documents, must be received by the Depositary at one of its addresses set forth on the back of this Letter of Transmittal at or prior to the Expiration Time and either certificates for tendered shares must be received by the Depositary at one of such addresses or shares must be delivered pursuant to the procedures for book-entry transfer set forth herein (and a book-entry confirmation must be received by the Depositary), in each case at or prior to the Expiration Time, or (b) the tendering stockholder must comply with the guaranteed delivery procedures set forth below and in Section 3 of the Offer to Purchase.

Stockholders whose certificates for shares are not immediately available or who cannot deliver their certificates and all other required documents to the Depositary or complete the procedures for book-entry transfer by the Expiration Time may tender their shares by properly completing and duly executing the Notice of Guaranteed Delivery pursuant to the guaranteed delivery procedures set forth in Section 3 of the Offer to Purchase. Pursuant to those procedures, (a) tender must be made by or through an eligible institution, (b) a properly completed and duly executed Notice of Guaranteed Delivery, in the form provided by the Company, must be received by the Depositary prior to the expiration of the Tender Offer and (c) the certificates for all tendered shares in proper form for transfer (or a book-entry confirmation with respect to all such shares), together with a Letter of Transmittal (or facsimile thereof), properly completed and duly executed, with any required signature guarantees, or, in the case of a book-entry transfer, an Agent’s Message, and any other required documents, must be received by the Depositary, in each case within three trading days after the date of execution of the Notice of Guaranteed Delivery as provided in Section 3 of the Offer to Purchase. A “trading day” is any day on which the New York Stock Exchange is open for business.

The method of delivery of shares, this Letter of Transmittal and all other required documents, including delivery through the Book-Entry Transfer Facility, is at the sole election and risk of the tendering stockholder. Shares will be deemed delivered only when actually received by the Depositary (including, in the case of a book-entry transfer, by book-entry confirmation). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

Except as specifically provided by the Offer to Purchase, no alternative, conditional or contingent tenders will be accepted. All tendering stockholders, by execution of this Letter of Transmittal (or a facsimile hereof), waive any right to receive any notice of the acceptance for payment of their shares.

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

4. Partial Tenders (Not Applicable to Stockholders Who Tender by Book-Entry Transfer). If fewer than all the shares represented by any certificate submitted to the Depositary are to be tendered, fill in the number of shares that are to be tendered in the box entitled “Number of Shares Tendered.” In that case, if any tendered shares are purchased, new certificate(s) for the remainder of the shares that were evidenced by the old certificate(s) will be sent to the registered holder(s), unless otherwise provided in the appropriate box on this Letter of Transmittal, as soon as practicable after the acceptance for payment of, and payment for, the shares tendered herewith. All shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

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

If any of the shares tendered hereby are owned of record by two or more joint owners, all such persons must sign this Letter of Transmittal.

If shares are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates.

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 other person acting in a fiduciary or representative capacity, he or she should so indicate when signing, and proper evidence satisfactory to the Company of his or her authority to so act must be submitted with this Letter of Transmittal.

If this Letter of Transmittal is signed by the registered owner(s) of the shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or certificates for shares not tendered or accepted for payment are to be issued, to a person other than the registered owner(s). Signatures on any such certificates or stock powers must be guaranteed by an eligible institution.

If this Letter of Transmittal is signed by a person other than the registered owner(s) of the shares tendered hereby, or if payment is to be made or certificate(s) for shares not tendered or not purchased are to be issued to a person other than the registered owner(s), the certificate(s) representing such shares must be properly endorsed for transfer or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered owner(s) appear(s) on the certificates(s). The signature(s) on any such certificate(s) or stock power(s) must be guaranteed by an eligible institution. See Instruction 1.

6. Stock Transfer Taxes. The Company will pay any stock transfer taxes with respect to the transfer and sale of shares to it pursuant to the Tender Offer. If, however, payment of the purchase price is to be made to, or if shares not tendered or accepted for payment are to be registered in the name of, any person(s) other than the registered owner(s), or if shares tendered hereby are registered in the name(s) of any person(s) other than the person(s) signing this Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered owner(s) or such person(s)) payable on account of the transfer to such person(s) will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes or exemption therefrom is submitted with this Letter of Transmittal.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the certificates listed in this Letter of Transmittal.

7. Special Payment and Delivery Instructions. If (a) certificates for shares not tendered or not accepted for payment and/or the check for payment of the purchase price of shares accepted for payment are to be issued in the name of someone other than the signer of this Letter of Transmittal, or (b) shares tendered hereby and delivered by book-entry transfer which are not purchased are to be returned by crediting them to an account at the Book-Entry Transfer Facility other than the account designated on page 2 above, or (c) certificates for shares not tendered or not accepted for payment and/or the check for payment of the purchase price of the shares accepted for payment are to be sent to someone other than the signer of this Letter of Transmittal or to the signer of this Letter of Transmittal at an address other than that above, the appropriate boxes on this Letter of Transmittal should be completed and signatures must be guaranteed as described in Instructions 1 and 5.

8. Irregularities. The Company will determine in its sole discretion all questions as to the number of shares to accept, and the validity, eligibility (including time of receipt), and acceptance for payment of any tender of shares. Any such determinations will be final and binding on all parties. The Company reserves the absolute right to reject any or all tenders of shares it determines not to be in proper form or the acceptance of which or payment for which may, in the Company’s opinion, be unlawful. The Company also reserves the right to waive any defect or irregularity in the tender of any particular shares, and the Company’s interpretation of the terms of the Tender Offer, including these instructions, will be final and binding on all parties. No tender of shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any defects or irregularities in connection with tenders must be cured within such time as the Company shall determine. None of the Company, the Lead Dealer Manager, the Co-Dealer Manager, the Depositary, the Information Agent or any other person is or will be obligated to give notice of any defects or irregularities in tenders and none of them will incur any liability for failure to give any such notice.

9. Tax Identification Number and Backup Withholding. TO ENSURE COMPLIANCE WITH TREASURY DEPARTMENT CIRCULAR 230, YOU ARE HEREBY NOTIFIED THAT: (A) ANY FEDERAL TAX ADVICE CONTAINED HEREIN IS NOT INTENDED OR WRITTEN TO BE USED, AND CANNOT BE USED, BY ANY TAXPAYER FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED UNDER THE INTERNAL REVENUE CODE; (B) THE ADVICE IS WRITTEN IN CONNECTION WITH THE PROMOTION OR MARKETING OF THE TRANSACTION OR THE MATTERS ADDRESSED HEREIN; AND (C) THE TAXPAYER SHOULD SEEK ADVICE BASED ON THE TAXPAYER’S PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR.

To prevent backup withholding, each U.S. Holder (as defined below) should either (x) provide his, her or its correct taxpayer identification number (“TIN”) by completing an IRS Form W-9, a copy of which is provided with this Letter of Transmittal and additional copies of which may be obtained from the Information Agent or the IRS website at www.irs.gov, certifying that (1) he, she or it is a “United States person” (as defined in section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), (2) the TIN provided is correct (or that such U.S. Holder is awaiting a TIN) and (3) that the U.S. Holder is exempt from backup withholding because (i) the holder has not been notified by the Internal Revenue Service (the “IRS”) that he, she or it is subject to backup withholding as a result of a failure to report all interest or dividends, or (ii) the IRS has notified the U.S. Holder that he, she or it is no longer subject to backup withholding or (y) the holder has otherwise established an exemption. If you do not provide the Depositary with the correct TIN or an adequate basis for exemption, you may be subject to a $50 penalty imposed by the IRS, and payments made to you pursuant to the Tender Offer may be subject to backup withholding at a rate of 28%. If withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is furnished to the IRS.

To prevent backup withholding, a Non-U.S. Holder (as defined below) should (i) submit a properly completed IRS Form W-8BEN or other appropriate IRS Form W-8 to the Depositary, certifying under penalties of perjury to the holder’s foreign status or (ii) otherwise establish an exemption. IRS Forms W-8 may be obtained from the Depositary or on the IRS website at www.irs.gov.

Certain holders (including, among others, corporations) are exempt recipients generally not subject to these backup withholding requirements. See IRS Form W-9 and the instructions thereto. To avoid possible erroneous backup withholding, exempt U.S. Holders, while not required to file an IRS Form W-9, should complete and return an IRS Form W-9 and check the “Exempt from backup withholding” box on its face.

For the purposes of these instructions, a “U.S. Holder” is (i) an individual who is a citizen or resident alien of the United States, (ii) a corporation (including an entity taxable as a corporation) created under the laws of the United States or of any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income tax regardless of its source or (iv) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. Holders that are, or hold their shares through, partnerships and other pass-through entities should consult their tax advisors regarding their treatment for purposes of these instructions. A “Non-U.S. Holder” is any holder (other than a holder that is, or holds its shares through, a partnership or other pass-through entity) that is not a U.S. Holder.

See the enclosed IRS Form W-9 and the instructions thereto for additional information and instructions.

Withholding on Non-U.S. Holders. Even if a Non-U.S. Holder (as defined above) has provided the required certification to avoid backup withholding tax, the Depositary may withhold U.S. federal income taxes equal to 30% of the gross payments payable to a Non-U.S. Holder or such holder’s agent unless the Depositary determines that a reduced rate of withholding is available pursuant to an applicable income tax treaty or that an exemption from withholding is applicable because such gross proceeds are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. In order to obtain a reduced rate of withholding pursuant to an income tax treaty, a Non-U.S. Holder must deliver to the Depositary before the payment a properly completed and executed IRS Form W-8BEN (or other applicable IRS Form W-8). In order to obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Tender Offer are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, a Non-U.S. Holder must deliver to the Depositary a properly completed and executed IRS Form W-8ECI. The Depositary will determine a stockholder’s status as a Non-U.S. Holder and eligibility for a reduced rate of, or an exemption from, withholding by reference to outstanding certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., IRS Form W-8BEN or IRS Form W-8ECI) unless facts and circumstances indicate that such reliance is not warranted.

A Non-U.S. Holder may be eligible to obtain a refund of all or a portion of any tax withheld if such Non-U.S. Holder meets those tests described in Section 13 of the Offer to Purchase that would characterize the exchange as a sale (as opposed to a distribution) for U.S. federal income tax purposes or is otherwise able to establish that no tax or a reduced amount of tax is due and the requisite information is timely furnished to the IRS.

HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF U.S. FEDERAL INCOME TAX WITHHOLDING AND BACKUP WITHHOLDING, INCLUDING ELIGIBILITY FOR A WITHHOLDING TAX REDUCTION OR EXEMPTION, AND THE REFUND PROCEDURE.

10. Requests for Assistance or Additional Copies. Questions and requests for assistance or additional copies of the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed Delivery or IRS Form W-9 may be directed to the Information Agent at its address set forth on the last page of this Letter of Transmittal.

11. Lost, Destroyed or Stolen Certificates. If your certificate(s) for part or all of your shares has been lost, stolen, destroyed or mutilated, you should contact the Depositary at 312-360-5104 to arrange for replacement of lost securities. You should also check the box for “Lost Certificates” in the box on the first page hereof and promptly send the completed Letter of Transmittal to the Depositary. Upon receipt of your request, the Depositary will provide you with instructions on how to obtain a replacement certificate. You may be asked to post a bond to secure against the risk that the certificate may be subsequently recirculated. There may be a fee,

and additional documents may be required to replace lost certificates. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, stolen, destroyed or mutilated certificates have been followed. You are urged to send the properly completed Letter of Transmittal to the Depositary immediately to ensure timely processing of documentation. If you have questions about the procedures for replacing lost, stolen, destroyed or mutilated certificates, you may contact the Depositary at 312-360-5104.

12. Conditional Tenders. As described in Sections 1 and 6 of the Offer to Purchase, stockholders may condition their tenders on all or a minimum number of their tendered shares being purchased.

If you wish to make a conditional tender, you must indicate this in the box captioned “Conditional Tender” in this Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery. In the space provided in the text adjacent to such box in this Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery, you must calculate and appropriately indicate the minimum number of shares that must be purchased from you if any are to be purchased from you.

As discussed in Sections 1 and 6 of the Offer to Purchase, proration may affect whether the Company accepts conditional tenders and may result in shares tendered pursuant to a conditional tender being deemed withdrawn if the required minimum number of shares would not be purchased. If, because of proration, the minimum number of shares that you designate will not be purchased, the Company 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 the box so indicating. Upon selection by lot, if any, the Company will limit its 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 the purchase of shares pursuant to the Tender Offer in such a manner that the purchase will be treated as a sale of such shares by the stockholder, rather than the payment of a dividend to the stockholder, for U.S. federal income tax purposes. If you are an odd lot holder and you tender all of your shares, you cannot conditionally tender, since your shares will not be subject to proration. 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 distribution) treatment for U.S. federal income tax purposes. Each stockholder is urged to consult his or her own tax advisor. No assurances can be provided that a conditional tender will achieve the intended U.S. federal income tax results in all cases. See Section 13 of the Offer to Purchase.

13. Odd Lots. As described in Section 1 of the Offer to Purchase, if the Company is to purchase fewer than all shares properly tendered before the expiration of the Tender Offer and not properly withdrawn, the shares purchased first will consist of all shares properly tendered by any stockholder who owned, beneficially or of record, an aggregate of fewer than 100 shares, and who tenders all of the holder’s shares. This preference will not be available to you unless you complete the section captioned “Odd Lots” in this Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery.

14. Order of Purchase in Event of Proration. As described in Section 1 of the Offer to Purchase, stockholders may designate the order in which their shares are to be purchased in the event of proration. The order of purchase may have an effect on the U.S. federal income tax classification of any gain or loss on the shares purchased. See Section 1 and Section 13 of the Offer to Purchase.

IMPORTANT. This Letter of Transmittal (or a manually signed facsimile hereof), together with any required signature guarantees, or, in the case of a book-entry transfer, an Agent’s Message, and any other required documents, must be received by the Depositary prior to the expiration of the Tender Offer and either certificates for tendered shares must be received by the Depositary or shares must be delivered pursuant to the procedures for book-entry transfer, in each case prior to the expiration of the Tender Offer, or the tendering stockholder must comply with the procedures for guaranteed delivery.

The Letter of Transmittal, certificates for shares and any other required documents should be sent or delivered by each stockholder of the Company or such stockholder’s bank, broker, dealer, trust company or other nominee to the Depositary at one of its addresses set forth below.

Delivery of this Letter of Transmittal to an address other than as set forth above will not constitute a valid delivery to the Depositary.

Questions and requests for assistance may be directed to the Information Agent at the address set forth below. Additional copies of the Offer to Purchase and this Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained from the Information Agent. You may also contact your bank, broker, dealer, trust company or other nominee for assistance concerning the Tender Offer.

Certification instructions. You must cross out item 2 above if you have been notified by the IRS that you are currently subject to backup withholding because you have failed to report all interest and dividends on your tax return. For real estate transactions, item 2 does not apply. For mortgage interest paid, acquisition or abandonment of secured property, cancellation of debt, contributions to an individual retirement arrangement (IRA), and generally, payments other than interest and dividends, you are not required to sign the Certification, but you must provide your correct TIN. (See the instructions on page 4.)

Purpose of Form

A person who is required to file an information return with the IRS, must obtain your correct taxpayer identification number (TIN) to report, for example, income paid to you, real estate transactions, mortgage interest you paid, acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA.

U.S. person. Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and, when applicable, to:

1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued),

2. Certify that you are not subject to backup withholding, or

3. Claim exemption from backup withholding if you are a U.S. exempt payee.

In 3 above, if applicable, you are also certifying that as a U.S. person, your allocable share of any partnership income from a U.S. trade or business is not subject to the withholding tax on foreign partners’ share of effectively connected income.

Note. If a requester gives you a form other than Form W-9 to request your TIN, you must use the requester’s form if it is substantially similar to this Form W-9.

For federal tax purposes, you are considered a person if you are:

· An individual who is a citizen or resident of the United States,

· A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States, or

· Any estate (other than a foreign estate) or trust. See Regulations sections 301.7701-6(a) and 7(a) for additional information.

Special rules for partnerships. Partnerships that conduct a trade or business in the United States are generally required to pay a withholding tax on any foreign partners’ share of income from such business. Further, in certain cases where a Form W-9 has not been received, a partnership is required to presume that a partner is a foreign person, and pay the withholding tax. Therefore, if you are a U.S. person that is a partner in a partnership conducting a trade or business in the United States, provide Form W-9 to the partnership to establish your U.S. status and avoid withholding on your share of partnership income.

The person who gives Form W-9 to the partnership for purposes of establishing its U.S. status and avoiding withholding on its allocable share of net income from the partnership conducting a trade or business in the United States is in the following cases:

· The U.S. owner of a disregarded entity and not the entity,

· The U.S. grantor or other owner of a grantor trust and not the trust, and

· The U.S. trust (other than a grantor trust) and not the beneficiaries of the trust.

Foreign person. If you are a foreign person, do not use Form W-9. Instead, use the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities).

Nonresident alien who becomes a resident alien.

Generally, only a nonresident alien individual may use the terms of a tax treaty to reduce or eliminate U.S. tax on certain types of income. However, most tax treaties contain a provision known as a “saving clause.” Exceptions specified in the saving clause may permit an exemption from tax to continue for certain types of income even after the recipient has otherwise become a U.S. resident alien for tax purposes.

If you are a U.S. resident alien who is relying on an exception contained in the saving clause of a tax treaty to claim an exemption from U.S. tax on certain types of income, you must attach a statement to Form W-9 that specifies the following five items:

1. The treaty country. Generally, this must be the same treaty under which you claimed exemption from tax as a nonresident alien.

2. The treaty article addressing the income.

3. The article number (or location) in the tax treaty that contains the saving clause and its exceptions.

4. The type and amount of income that qualifies for the exemption from tax.

5. Sufficient facts to justify the exemption from tax under the terms of the treaty article.

Example. Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under U.S. law, this student will become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April 30, 1984) allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States. A Chinese student who qualifies for this exception (under paragraph 2 of the first protocol) and is relying on this exception to claim an exemption from tax on his or her scholarship or fellowship income would attach to Form W-9 a statement that includes the information described above to support that exemption.

If you are a nonresident alien or a foreign entity not subject to backup withholding, give the requester the appropriate completed Form W-8.

What is backup withholding? Persons making certain payments to you must under certain conditions withhold and pay to the IRS 28% of such payments (after December 31, 2002). This is called “backup withholding.” Payments that may be subject to backup withholding include interest, dividends, broker and barter exchange transactions, rents,

royalties, nonemployee pay, and certain payments from fishing boat operators. Real estate transactions are not subject to backup withholding.

You will not be subject to backup withholding on payments you receive if you give the requester your correct TIN, make the proper certifications, and report all your taxable interest and dividends on your tax return.

Payments you receive will be subject to backup withholding if:

1. You do not furnish your TIN to the requester,

2. You do not certify your TIN when required (see the Part II instructions on page 4 for details),

3. The IRS tells the requester that you furnished an incorrect TIN,

4. The IRS tells you that you are subject to backup withholding because you did not report all your interest and dividends on your tax return (for reportable interest and dividends only), or

5. You do not certify to the requester that you are not subject to backup withholding under 4 above (for reportable interest and dividend accounts opened after 1983 only).

Certain payees and payments are exempt from backup withholding. See the instructions below and the separate Instructions for the Requester of Form W-9.

Also see Special rules regarding partnerships on page 1.

Penalties

Failure to furnish TIN. If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

Civil penalty for false information with respect to withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

Criminal penalty for falsifying information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

Specific Instructions

Name

If you are an individual, you must generally enter the name shown on your income tax return. However, if you have changed your last name, for instance, due to marriage without informing the Social Security Administration of the name change, enter your first name, the last name shown on your social security card, and your new last name.

If the account is in joint names, list first, and then circle, the name of the person or entity whose number you entered in Part I of the form.

Sole proprietor. Enter your individual name as shown on your income tax return on the “Name” line. You may enter your business, trade, or “doing business as (DBA)” name on the “Business name” line.

Limited liability company (LLC). If you are a single-member LLC (including a foreign LLC with a domestic owner) that is disregarded as an entity separate from its owner under Treasury regulations section 301.7701-3, enter the owner’s name on the “Name” line. Enter the

LLC’s name on the “Business name” line. Check the appropriate box for your filing status (sole proprietor, corporation, etc.), then check the box for “Other” and enter “LLC” in the space provided.

Exempt From Backup Withholding

If you are exempt, enter your name as described above and check the appropriate box for your status, then check the “Exempt from backup withholding” box in the line following the business name, sign and date the form.

Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations are exempt from backup withholding for certain payments, such as interest and dividends.

Note. If you are exempt from backup withholding, you should still complete this form to avoid possible erroneous backup withholding.

Exempt payees. Backup withholding is not required on any payments made to the following payees:

The chart below shows types of payments that may be exempt from backup withholding. The chart applies to the exempt recipients listed above, 1 through 15.


IF the payment is for . . .		THEN the payment is exempt for . . .
Interest and dividend payments		All exempt recipients except for 9

¹	See Form 1099-MISC, Miscellaneous Income, and its instructions.

However, the following payments made to a corporation (including gross proceeds paid to an attorney under section 6045(f), even if the attorney is a corporation) and reportable on Form 1099-MISC are not exempt from backup withholding: medical and health care payments, attorneys’ fees; and payments for services paid by a federal executive agency.

Part I. Taxpayer Identification Number (TIN)

Enter your TIN in the appropriate box. If you are a resident alien and you do not have and are not eligible to get an SSN, your TIN is your IRS individual taxpayer identification number (ITIN). Enter it in the social security number box. If you do not have an ITIN, see How to get a TIN below.

If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN. However, the IRS prefers that you use your SSN.

If you are a single-owner LLC that is disregarded as an entity separate from its owner (see Limited liability company (LLC) on page 2), enter your SSN (or EIN, if you have one). If the LLC is a corporation, partnership, etc., enter the entity’s EIN.

Note: See the chart on page 4 for further clarification of name and TIN combinations.

How to get a TIN. If you do not have a TIN, apply for one immediately. To apply for an SSN, get Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at www.socialsecurity.gov. You may also get this form by calling 1-800-772-1213. Use Form W-7, Application for IRS Individual Taxpayer Identification Number, to apply for an ITIN, or Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses and clicking on Employer ID Numbers under Related Topics. You can get Forms W-7 and SS-4 from the IRS by visiting www.irs.gov or by calling 1-800-TAX-FORM (1-800-829-3676).

If you are asked to complete Form W-9 but do not have a TIN, write “Applied For” in the space for the TIN, sign and date the form, and give it to the requester. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.

Note: Writing “Applied For” means that you have already applied for a TIN or that you intend to apply for one soon.

Caution: A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.

Part II. Certification

To establish to the withholding agent that you are a U.S. person, or resident alien, sign Form W-9. You may be requested to sign by the withholding agent even if items 1, 4, and 5 below indicate otherwise.

For a joint account, only the person whose TIN is shown in Part I should sign (when required). Exempt recipients, see Exempt From Backup Withholding on page 2.

Signature requirements. Complete the certification as indicated in 1 through 5 below.

1. Interest, dividend, and barter exchange accounts opened before 1984 and broker accounts considered active during 1983. You must give your correct TIN, but you do not have to sign the certification.

2. Interest, dividend, broker, and barter exchange accounts opened after 1983 and broker accounts considered inactive during 1983. You must sign the certification or backup withholding will apply. If you are subject to backup withholding and you are merely providing your correct TIN to the requester, you must cross out item 2 in the certification before signing the form.

3. Real estate transactions. You must sign the certification. You may cross out item 2 of the certification.

4. Other payments. You must give your correct TIN, but you do not have to sign the certification unless you have been notified that you have previously given an incorrect TIN. “Other payments” include payments made in the course of the requester’s trade or business for rents, royalties, goods (other than bills for merchandise), medical and health care services (including payments to corporations), payments to a nonemployee for services, payments to certain fishing boat crew members and fishermen, and gross proceeds paid to attorneys (including payments to corporations).

5. Mortgage interest paid by you, acquisition or abandonment of secured property, cancellation of debt, qualified tuition program payments (under section 529), IRA, Coverdell ESA, Archer MSA or HSA contributions or distributions, and pension distributions. You must give your correct TIN, but you do not have to sign the certification.

Section 6109 of the Internal Revenue Code requires you to provide your correct TIN to persons who must file information returns with the IRS to report interest, dividends, and certain other income paid to you, mortgage interest you paid, the acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA, or Archer MSA or HSA. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, the District of Columbia, and U.S. possessions to carry out their tax laws. We may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism.

You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.
