This letter of transmittal (as amended or supplemented from time to time, this “Letter of Transmittal”) is to be completed by stockholders of SuccessFactors, Inc., a Delaware corporation (“SuccessFactors”), if certificates (“Certificates”) representing shares of common stock, par value $0.001 per share (the “SuccessFactors Common Stock” or the “Shares”) of SuccessFactors are to be forwarded with this Letter of Transmittal.

The undersigned hereby tenders to Saturn Expansion Corporation, a Delaware corporation (the “Purchaser”) and a wholly-owned subsidiary of SAP America, Inc., a Delaware corporation (“SAP America”) and an indirectly wholly-owned subsidiary of SAP AG, a stock corporation organized under the laws of the Federal Republic of Germany (“SAP AG”), the above-described shares of common stock, par value $0.001 per share (the “SuccessFactors Common Stock” or the “Shares”), of SuccessFactors, Inc., a Delaware corporation (“SuccessFactors”), pursuant to the Purchaser’s offer to purchase all of the issued and outstanding Shares at $40.00 per Share, net to the holder thereof in cash, without interest and less any required withholding of taxes, upon the terms and subject to the conditions set forth in the offer to purchase dated December 16, 2011 (as it may be amended or supplemented from time to time, the “Offer to Purchase”), receipt of which is hereby acknowledged, and in this letter of transmittal (as amended or supplemented from time to time, this “Letter of Transmittal,” and together with the Offer to Purchase, the “Offer”). The Offer expires at 5:00 p.m., New York City time, on Wednesday, January 18, 2012, unless extended as described in the Offer to Purchase (such time, as may be extended as described in the Offer to Purchase, the “Expiration Time”). The undersigned understands that Purchaser reserves the right to transfer or assign, from time to time, in whole or in part, to any direct or indirect subsidiary of Purchaser, the right to purchase the Shares tendered herewith but that any such transfer or assignment will not relieve Purchaser of its obligations under the Offer and will in no way prejudice the undersigned’s right to receive payment for the Shares validly tendered and not withdrawn pursuant to the Offer.

Subject to, and effective upon, acceptance for payment of the Shares tendered with this Letter of Transmittal, in accordance with the terms of the Offer (including, if the Offer is extended or amended, the terms and conditions of any extension or amendment), the undersigned hereby sells, assigns and transfers to, or upon the order of, the Purchaser all right, title and interest in and to all the Shares that are being tendered by this Letter of Transmittal and all dividends, distributions (including, without limitation, distributions of additional Shares or other securities) and rights declared, paid or distributed in respect of such Shares on or after December 16, 2011 (collectively, “Distributions”) and irrevocably appoints American Stock Transfer & Trust Company, LLC (the “Depositary”) as the true and lawful agent, attorney-in-fact and proxy of the undersigned with respect to such Shares and all Distributions, with full power of substitution (such proxies and power of attorney being deemed to be an irrevocable power coupled with an interest in the Shares tendered by this Letter of Transmittal), to (i) deliver certificates representing the SuccessFactors Common Stock (“Certificates”) and any and all Distributions, or transfer ownership of such Shares and all Distributions on the account books maintained by the The Depository Trust Company (the “DTC”), together, in either case, with all accompanying evidences of transfer and authenticity, to or upon the order of the Purchaser; (ii) present such Shares and any and all Distributions for transfer on the books of SuccessFactors; and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares and any and all Distributions, all in accordance with the terms and subject to the conditions of the Offer.

The undersigned hereby irrevocably appoints the Purchaser, its officers and designees, and each of them, as agents, attorneys-in-fact and proxies of the undersigned, each with full power of substitution, in the manner set forth herein, to the full extent of the rights of the undersigned with respect to Shares that the undersigned tenders and the Purchaser accepts for payment and with respect to any and all other Distributions. All such powers of attorney and proxies will be considered irrevocable and coupled with an interest in the Shares tendered by this Letter of Transmittal. This appointment will be effective if and when, and only to the extent that the Purchaser accepts the Shares tendered by this Letter of Transmittal for payment in accordance with the terms of the Offer. Upon acceptance for payment, all other powers of attorney and proxies given by the undersigned with respect to the Shares tendered by this Letter of Transmittal and other securities or rights prior to such payment will be revoked, without further action, and no subsequent powers of attorney and proxies may be given by the undersigned (and, if given, will not be deemed effective). The Purchaser or its officers and designees will, with

respect to the Shares tendered by this Letter of Transmittal and other securities and rights for which the appointment is effective, be empowered to exercise all of the voting and other rights of the undersigned as they, in their sole discretion, may deem proper at any annual or special meeting of stockholders of SuccessFactors, or any adjournment or postponement thereof, or by consent in lieu of any such meeting of stockholders of SuccessFactors or otherwise. In order for Shares to be deemed validly tendered by this Letter of Transmittal, immediately upon the acceptance for payment of such Shares, the Purchaser or its officers and designees must be able to exercise full voting rights with respect to such Shares and other securities, including voting at any meeting of stockholders of SuccessFactors.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered by this Letter of Transmittal and all Distributions, and that when such Shares are accepted for payment by the Purchaser, the Purchaser will acquire good, marketable and unencumbered title to such Shares and to all Distributions, free and clear of all liens, restrictions, charges and encumbrances, and that none of such Shares and Distributions will be subject to any adverse claim. The undersigned, upon request, shall execute and deliver all additional documents deemed by the Depositary or the Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered by this Letter of Transmittal and all Distributions. In addition, the undersigned shall remit and transfer promptly to the Depositary for the account of the Purchaser all Distributions in respect of the Shares tendered by this Letter of Transmittal, accompanied by appropriate documentation of transfer, and pending such remittance and transfer or appropriate assurance thereof, the Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of the Shares tendered by this Letter of Transmittal, or deduct from such purchase price, the amount or value of such Distribution as determined by the Purchaser in its sole discretion.

No authority conferred or agreed to be conferred in this Letter of Transmittal shall be affected by, and all such authority shall survive, the death or incapacity of the undersigned. All obligations of the undersigned under this Letter of Transmittal shall be binding upon the heirs, executors, administrators, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable. See Section 4—“Withdrawal Rights” of the Offer to Purchase.

The undersigned understands that tenders of Shares pursuant to any one of the procedures described in the Offer to Purchase under Section 3—“Procedures for Accepting the Offer and Tendering Shares” 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. The Purchaser’s acceptance of such Shares for payment will constitute a binding agreement between the undersigned and the Purchaser upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any extension or amendment). Without limiting the foregoing, if the price to be paid in the Offer is amended in accordance with the Offer, the price to be paid to the undersigned will be the amended price notwithstanding the fact that a different price is stated in this Letter of Transmittal. The undersigned recognizes that under certain circumstances set forth in the Offer to Purchase, the Purchaser may not be required to accept for payment any of the Shares tendered by this Letter of Transmittal.

Unless otherwise indicated in this Letter of Transmittal in the box entitled “Special Payment Instructions,” please issue the check for the purchase price of all Shares purchased, and return all Certificates not purchased or not tendered in the name(s) of the registered holder(s) appearing above under “Description of Shares Tendered.” Similarly, unless otherwise indicated in the box entitled “Special Delivery Instructions,” please mail the check for the purchase price of all Shares purchased and all Certificates not tendered or not purchased (and accompanying documents, as appropriate) to the address(es) of the registered holder(s) appearing above under “Description of Shares Tendered.” In the event that the boxes entitled “Special Payment Instructions” and “Special Delivery Instructions” are both completed, please issue the check for the purchase price of all Shares purchased and return

all Certificates not purchased or not tendered in the name(s) of, and mail such check and Certificates to, the person(s) so indicated. Please credit any Shares tendered by this Letter of Transmittal and delivered by book-entry transfer, but which are not purchased, by crediting the account at the DTC. The undersigned recognizes that the Purchaser has no obligation, pursuant to the Special Payment Instructions, to transfer any Shares from the name of the registered holder(s) of such Shares if the Purchaser does not purchase any of the Shares tendered by this Letter of Transmittal.

If you complete the box entitled “Special Payment Instructions” or “Special Delivery Instructions,” you must have your signature guaranteed by an Eligible Institution (as defined in Instruction 1 below) unless the Letter of Transmittal is signed by an Eligible Institution.

1. Guarantee of Signatures. All signatures on this Letter of Transmittal must be guaranteed by a bank, broker, dealer, credit union, savings association or other entity that is a member in good standing of the Securities Transfer Agents Medallion Program or any other “eligible guarantor institution,” as defined in Rule 17Ad-15 of the Securities Exchange Act of 1934, as amended (each, an “Eligible Institution” and collectively, “Eligible Institutions”), unless (a) this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this document, shall include any participant in the DTC whose name appears on a security position listing as the owner of the Shares) of the Shares tendered by this Letter of Transmittal and such holder(s) has not completed either the box entitled “Special Payment Instructions” or the box entitled “Special Delivery Instructions” in this Letter of Transmittal or (b) the Shares tendered by this Letter of Transmittal are tendered for the account of an Eligible Institution. If a Certificate is registered in the name of a person other than the person signing this Letter of Transmittal, or if payment is to be made to, or a Certificate for unpurchased Shares is to be issued or returned to, a person other than the registered holder(s), then such tendered Certificate must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on such Certificate, with the signatures on such Certificate or stock powers guaranteed by an Eligible Institution as described above. See Instruction 5.

2. Delivery of Letter of Transmittal and Certificates. This Letter of Transmittal is to be used if Certificates are to be forwarded with this Letter of Transmittal. If delivery of Shares is to be made by book-entry transfer to an account maintained by the Depositary at the DTC pursuant to the procedures set forth under Section 3—“Procedures for Accepting the Offer and Tendering Shares” of the Offer to Purchase, stockholders may use an Agent’s Message (as defined below) or this Letter of Transmittal. Certificates representing all tendered Shares, or timely confirmation of a book-entry transfer of such

Shares (“Book-Entry Confirmation”) into the Depositary’s account at the DTC, together with a properly completed and duly executed Letter of Transmittal (or facsimile of the Letter of Transmittal, which is permitted solely in the case of book-entry transfer), or an Agent’s Message in the case of book-entry transfer, and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth in this Letter of Transmittal prior to the Expiration Time. If Certificates are forwarded to the Depositary in multiple deliveries, a properly completed and duly executed Letter of Transmittal must accompany each such delivery.

Stockholders whose Certificates are not immediately available, who cannot deliver their Certificates and all other required documents to the Depositary prior to the Expiration Time or who cannot complete the procedure for delivery by book-entry transfer prior to the Expiration Time, may tender their Shares pursuant to the guaranteed delivery procedure described under Section 3—“Procedures for Accepting the Offer and Tendering Shares” in the Offer to Purchase. Pursuant to such procedure: (a) such tender must be made by or through an Eligible Institution; (b) the Depositary must receive a properly completed and signed Notice of Guaranteed Delivery at or before the Expiration Time, substantially in the form made available by the Purchaser; and (c) the Depositary must receive Certificates (or a Book-Entry Confirmation) representing all tendered Shares, in proper form for transfer together with a properly completed and duly executed Letter of Transmittal), with any required signature guarantees (or, in the case of a book-entry transfer, an Agent’s Message), and any other documents required by this Letter of Transmittal within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as described under Section 3—“Procedures for Accepting the Offer and Tendering Shares” in the Offer to Purchase.

Delivery of the Notice of Guaranteed Delivery may be made by mail or facsimile transmission to the Depositary. The Notice of Guaranteed Delivery must include a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery.

The term “Agent’s Message” means a message transmitted by the DTC to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, which message states that the DTC has received an express acknowledgment from the participant in the DTC tendering the Shares that are the subject of the Book-Entry Confirmation that the participant has received and agrees to be bound by the terms of this Letter of Transmittal and that the Purchaser may enforce that agreement against the participant.

THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE DTC, IS AT THE OPTION AND SOLE RISK OF THE TENDERING STOCKHOLDER, AND THE DELIVERY WILL BE CONSIDERED TO BE MADE 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 ENCOURAGED AND STRONGLY RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY PRIOR TO THE EXPIRATION TIME.

No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be purchased. By execution of the Letter of Transmittal (or facsimile of the Letter of Transmittal, which is permitted solely in the case of book-entry transfer), all tendering stockholders waive any right to receive any notice of the acceptance of their Shares for payment.

All questions as to the form of documents and the validity, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by the Purchaser, in its sole discretion. The Purchaser reserves the absolute right, subject to the terms of the Merger Agreement and applicable law, to reject any or all tenders determined by the Purchaser not to be in proper form or

the acceptance of or payment for which may, in the opinion of the Purchaser’s counsel, be unlawful. The Purchaser also reserves the absolute right to waive any of the conditions of the Offer, except the Minimum Condition (which waiver requires SuccessFactors’ prior written consent) or any defect or irregularity in any tender of Shares of any particular stockholder of SuccessFactors, whether or not similar defects or irregularities are waived in the case of other stockholders of SuccessFactors. All questions as to the interpretation of the terms and conditions of the Offer will be determined by the Purchaser, in its sole discretion. No tender of Shares will be deemed to have been validly made until all defects and irregularities with respect to the tender have been cured or waived by the Purchaser. None of SAP America, the Purchaser or any of their respective affiliates or assigns, the Depositary, the Dealer Manager, the Information Agent or any other person or entity will be under any duty to give any notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification.

3. Inadequate Space. If the space provided in this Letter of Transmittal under “Description of Shares Tendered” is inadequate, the certificate numbers, the number of Shares represented by such Certificates and the number of Shares tendered should be listed on a separate schedule and attached to this Letter of Transmittal.

4. Partial Tenders (Not Applicable to Stockholders who Tender by Book-Entry Transfer). If fewer than all the Shares represented by any Certificate delivered to the Depositary with this Letter of Transmittal are to be tendered by this Letter of Transmittal, fill in the number of Shares which are to be tendered in the box entitled “Number of Shares Tendered.” In such cases, a new certificate representing the remainder of the Shares that were represented by the Certificates delivered to the Depositary with this Letter of Transmittal will be sent to each person signing this Letter of Transmittal, unless otherwise provided in the box entitled “Special Delivery Instructions” in this Letter of Transmittal, as promptly as practicable after the expiration, termination or withdrawal of the Offer. 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 by this Letter of Transmittal, the signature(s) must correspond with the name(s) as written on the face of the Certificates evidencing such Shares without alteration, enlargement or any other change whatsoever.

If any Share tendered by this Letter of Transmittal is owned of record by two or more persons, all such persons must sign this Letter of Transmittal.

If any of the Shares tendered by this Letter of Transmittal are registered in the names of different holders, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of such Shares.

If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered by this Letter of Transmittal, no endorsements of Certificates or separate stock powers are required, unless payment is to be made to, or Certificates for unpurchased Shares are to be issued in the name of, a person other than the registered holder(s), in which case, the Certificate(s) representing the Shares tendered by this Letter of Transmittal must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear on such Certificate(s). Signatures on such Certificate(s) and stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered by this Letter of Transmittal, the Certificate(s) representing the Shares tendered by this Letter of Transmittal must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on such Certificate(s). Signatures on such Certificate(s) and stock powers must be guaranteed by an Eligible Institution.

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, such person should so indicate when signing, and proper evidence satisfactory to the Purchaser of such person’s authority to so act must be submitted.

6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6, the Purchaser will pay all stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price of any Shares purchased is to be made to, or Certificate(s) representing Shares not tendered or not purchased are to be issued in the name of, a person other than the registered holder(s), the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person or otherwise) payable on account of the transfer to such other person will be deducted from the purchase price of such Shares purchased, unless evidence satisfactory to the Purchaser of the payment of such taxes, or exemption therefrom, is submitted.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Certificates representing the Shares tendered by this Letter of Transmittal.

7. Special Payment and Delivery Instructions. If a check for the purchase price of any Shares tendered by this Letter of Transmittal is to be issued, or Certificate(s) representing Shares not tendered or not purchased are to be issued, in the name of a person other than the person(s) signing this Letter of Transmittal or if such check or any such Certificate is to be sent to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal but at an address other than that shown in the box entitled “Description of Shares Tendered” in this Letter of Transmittal, the appropriate boxes in this Letter of Transmittal must be completed.

8. Waiver of Conditions. Subject to the Offer to Purchase, SAP America and the Purchaser reserve the absolute right in their sole discretion to waive, at any time and from time to time, any of the specified conditions of the Offer, in whole or in part, in the case of any Shares tendered, except that the Minimum Condition (as defined in the Introduction to the Offer to Purchase) may not be waived. See Section 14—“Conditions of the Offer” of the Offer to Purchase.

9. Lost, Destroyed or Stolen Certificates. If any Certificate(s) have been lost, destroyed or stolen, the stockholder should promptly notify SuccessFactors’s transfer agent, Computershare, Inc. (the “Transfer Agent”), at (800) 962-4284 (toll free) or (781) 575-3120. THE STOCKHOLDER WILL THEN BE PROVIDED WITH INSTRUCTIONS AS TO THE PROCEDURES FOR REPLACING THE CERTIFICATE(S). THIS LETTER OF TRANSMITTAL AND RELATED DOCUMENTS CANNOT BE PROCESSED UNTIL THE PROCEDURES FOR REPLACING LOST, DESTROYED OR STOLEN CERTIFICATES HAVE BEEN FOLLOWED AND COMPLETED. The Depositary may charge holders an administrative fee for processing payment with respect to Shares represented by lost certificates.

10. Questions and Requests for Assistance or Additional Copies. Questions and requests for assistance may be directed to the Information Agent or the Dealer Manager at their respective addresses or telephone numbers set forth below. Additional copies of the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed Delivery and the Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 may be obtained from the Information Agent or from brokers, dealers, commercial banks or trust companies. An applicable IRS Form W-8 will be provided by the Depositary upon request.

11. Substitute Form W-9. To avoid backup withholding, unless an exemption applies and is adequately established, a stockholder of SuccessFactors that is a U.S. person (as defined for United States federal income tax purposes) must provide the Depositary with such stockholder’s correct taxpayer identification number (“TIN”) and certify under penalties of perjury that the TIN is correct and that such stockholder is not subject to backup withholding by completing the Substitute Form W-9

included in the Letter of Transmittal. A tendering stockholder must cross out item (2) in the “Certification” of the Substitute Form W-9 if the stockholder has been notified by the Internal Revenue Service (the “IRS”) that such stockholder is subject to backup withholding. If a stockholder of SuccessFactors does not provide (a) its correct TIN and fails to provide the certifications described above or (b) an otherwise adequate basis of exemption, the IRS may impose a penalty on such stockholder and any payment made to such stockholder pursuant to the Offer or the Merger may be subject to backup withholding at a rate of 28%. If the tendering stockholder has not been issued a TIN and has applied for one or intends to apply for one in the near future, such stockholder should write “Applied For” in the space provided for the TIN in Part I of the Substitute Form W-9, and sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number. If “Applied For” is written in Part I and the Depositary is not provided with a TIN by the time of payment, the Depositary will withhold 28% from any payments of the purchase price to such stockholder. A tendering stockholder that is not a U.S. person may qualify as an exempt recipient by submitting to the Depositary a properly completed IRS Form W-8BEN, Form W-8ECI or Form W-8IMY, as applicable (which the Depositary will provide upon request) signed under penalties of perjury, attesting to that stockholder’s exempt status. Such stockholder should consult a tax advisor to determine which form is appropriate.

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF, WHICH IS PERMITTED SOLELY IN THE CASE OF BOOK-ENTRY TRANSFER), 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 TIME, 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 TIME, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY.

A stockholder whose tendered Shares are accepted for payment and who is a U.S. person (as defined for United States federal income tax purposes) is required to provide the Depositary with such stockholder’s correct TIN on the Substitute Form W-9 below or otherwise establish to the satisfaction of the Depositary an adequate basis for exemption from backup withholding. If such stockholder is an individual, the TIN is such stockholder’s social security number. If the Depositary is not provided with the correct TIN or an adequate basis for exemption, payments made to such stockholder with respect to Shares purchased pursuant to the Offer may be subject to backup withholding of 28% and the stockholder may be subject to a penalty imposed by the IRS.

Certain stockholders (including, among others, corporations and certain foreign individuals and entities) are not subject to these backup withholding requirements. Exempt stockholders should indicate their exempt status on the Substitute Form W-9. A foreign person may qualify as an exempt recipient by submitting to the Depositary a properly completed IRS Form W-8BEN, Form W-8ECI or Form W-8IMY, as applicable (instead of a Substitute Form W-9), signed under penalties of perjury, attesting to such stockholder’s exempt status. Stockholders are urged to consult their own tax advisors to determine whether they are exempt from or otherwise not subject to backup withholding.

If backup withholding applies, the Depositary is required to withhold and pay over to the IRS 28% of the purchase price paid to the stockholder or other payee. Backup withholding is not an additional federal income tax. Any amounts withheld under the backup withholding rules from payments made to a stockholder of SuccessFactors may be refunded or credited against such stockholder’s United States federal income tax liability, if any, provided that the required information is timely furnished to the IRS. If the required information is furnished to the IRS in a timely manner, the federal income tax liability of persons subject to backup withholding may be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained from the IRS.

To prevent backup withholding on any payments that are made to a stockholder that is a U.S. person with respect to Shares purchased pursuant to the Offer, the stockholder is required to provide the Depositary with (i) the stockholder’s correct TIN by completing the Substitute Form W-9 below, certifying under penalties of perjury (a) that the TIN provided on the Substitute Form W-9 is correct, (b) that such stockholder is not subject to backup withholding because (A) the stockholder is exempt from backup withholding, (B) the stockholder has not been notified by the IRS that the stockholder is subject to backup withholding as a result of a failure to report all interest or dividends, or (C) the IRS has notified the stockholder that the stockholder is no longer subject to backup withholding, and (c) that such stockholder is a U.S. person (including a United States resident alien), or (ii) if applicable, an adequate basis for exemption.

The stockholder is required to give the Depositary the TIN (e.g., social security number or employer identification number) of the record holder of the Shares tendered by this Letter of Transmittal. If the Shares are in more than one name or are not in the name of the actual owner, consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidance on which number to report.

FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE SERVICE.

I understand that if I do not provide a taxpayer identification number by the time of payment, 28% of all reportable payments made to me will be withheld until I provide a number.
