1. Properly complete, date and sign the withdrawal form that you received in the email from Khue Nguyen, dated December 21, 2012; and

These options will continue to be governed by the plan under which they were granted, and by the existing option agreements between you and ServiceSource.

7. Neither my participation in the Offer nor this withdrawal shall be construed so as to grant me any right to remain in the employ of the ServiceSource Group and shall not interfere with the ability of my current employer to terminate my employment relationship at any time with or without cause.
8. For the exclusive purpose of implementing, administering and managing my participation in the Offer, I hereby explicitly and unambiguously consent to the collection, receipt, use, retention and transfer, in electronic or other form, of my personal data as described in this document by and among, as applicable, my employer, ServiceSource and its subsidiaries and affiliates, SOS and any other party assisting ServiceSource with the Offer ("Data Recepients").

In that regard, I authorize ServiceSource and/or its subsidiaries to withhold all Applicable Withholdings legally payable by me from my wages, from the proceeds of any stock sales, either through a voluntary sale or through a mandatory sale arranged by ServiceSource (on my behalf pursuant to this authorization) or other cash payments paid to me by ServiceSource and/or its subsidiaries.

WITHDRAWAL INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

1. Delivery of the Withdrawal.

To withdraw your election to exchange some or all of your Eligible Options, you must submit a withdrawal form by following the instructions set forth on pages 1-3 above by the Expiration Date, currently expected to be 9:00 p.m., Pacific Time, on January 22, 2013.

Your delivery of all documents regarding the Offer, including elections and withdrawals, is at your risk. Delivery will be deemed made only when actually received by us. If you submit your election or withdrawal via the Stock & Option Solutions, Inc. ("SOS") website, you should print and keep a copy of the Confirmation Statement on the SOS website at the time that you complete and submit your election or withdrawal. The printed Confirmation Statement will provide evidence that you submitted your election or withdrawal. If you submit your election or withdrawal via email or facsimile, we intend to confirm the receipt of your election or withdrawal by email within two (2) U.S. business days of receiving your election or withdrawal. If you have not received a Confirmation Statement, it is your responsibility to confirm that we have received your election and/or any withdrawal. Only responses that are properly completed and actually received by ServiceSource by the deadline by the SOS website at https://servicesource.equitybenefits.com or by Khue Nguyen by email at knguyen@servicesource.com, or facsimile at (415) 962-3246 will be accepted. Responses submitted by any other means, including hand delivery, interoffice or U.S. mail (or other post) and Federal Express (or similar delivery service), are not permitted. Note that if you submit any election and/or withdrawal via email or facsimile within the last two (2) U.S. business days prior to the expiration of the Offer, time constraints may prevent ServiceSource from providing you with an email confirmation prior to the expiration of the Offer.

Although by submitting a withdrawal you have withdrawn some or all of your previously tendered option grants from the Offer, you may change your mind and re-elect to exchange some or all of the withdrawn Eligible Option Grants until the expiration of the Offer. Each time you make a withdrawal via the SOS website, please be sure to select either "Yes" or "No" with respect to each of your Eligible Options. You should note that you may not rescind any withdrawal and any Eligible Option Grants withdrawn will not be deemed properly tendered for purposes of the Offer, unless you properly re-elect to exchange those Eligible Option Grants before 9:00 p.m., Pacific Time, on the Expiration Date. Tenders to re-elect to exchange Eligible Option Grants may be made at any time before 9:00 p.m., Pacific Time, on the Expiration Date. If ServiceSource extends the Offer beyond that time, you may re-tender your Eligible Option Grants at any time until the extended expiration of the Offer. The exception to this rule is that if we have not accepted your properly tendered option grants by 9:00 p.m., Pacific Time, on January 22, 2013, you may withdraw your option grants at any time thereafter.

To re-elect to tender the withdrawn Eligible Option Grants, you must follow the instructions set forth in, and complete and submit, the Election Form included as one of the documents that comprise this Offer following the last withdrawal you submitted but on or before 9:00 p.m., Pacific Time, on January 22, 2013 (unless we extend the Offer). Please see the ServiceSource International, Inc. Offer to Exchange Certain Outstanding Options for New Options-Election Form to re-elect to exchange any or all of your Eligible Options.

Please note that your awards will not be deemed properly tendered for purposes of the Offer unless the withdrawn option grants are properly re-tendered for exchange before 9:00 p.m., Pacific Time, on the Expiration Date by delivery of a new election following the procedures described in the instructions to the election. Such new election must be received by us after any election and any withdrawal you previously have submitted. Upon the receipt of such a new, properly completed election, any previously submitted elections and/or withdrawals will be disregarded and will be considered replaced in full by the new election. Any prior election will be disregarded; therefore, your new election must indicate all Eligible Option Grants you wish to exchange, not just those you wish to add. You will be bound by the last properly submitted election and/or withdrawal received by us prior to 9:00 p.m., Pacific Time, on the Expiration Date.

- 1 -

Although it is our intent to send you an email confirmation of receipt of this withdrawal, by completing and submitting this withdrawal, you waive any right to receive any notice of the withdrawal of the tender of your Eligible Options.

2. Signatures on this Withdrawal.

If the withdrawal is being submitted via email or facsimile, it must be signed by the holder of the Eligible Options and the signature must correspond with the name as written on the face of the option agreement or agreements to which the Eligible Options are subject without alteration, enlargement or any change whatsoever. If this withdrawal 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, that person should so indicate when signing, and proper evidence satisfactory to ServiceSource of the authority of that person to act in that capacity must be submitted with this withdrawal via email or facsimile.

Withdrawals submitted via the SOS website:

Logging into the SOS website and completing and submitting your withdrawal via the SOS website is the equivalent of signing your name on a paper form and has the same legal effect as your written signature.

3. Other Information on this Withdrawal.

If you are submitting your withdrawal via email or facsimile, in addition to completing and signing the withdrawal form, you must print your name and indicate the date and time at which you signed. You also must include a current email address.

4. Requests for Assistance or Additional Copies.

Any questions or requests for additional copies of the Offer to Exchange or this Withdrawal Form should be directed to Khue Nguyen by email at knguyen@servicesource.com or at (415) 901-7709. Copies will be furnished promptly at ServiceSource's expense.

5. Irregularities.

We will determine, in our discretion, all questions as to the form of documents and the validity, form, eligibility, including time of receipt, and acceptance of any withdrawal. Our determination of these matters will be given the maximum deference permitted by law. However, you have all rights accorded to you under applicable law to challenge such determination in a court of competent jurisdiction. Only a court of competent jurisdiction can make a determination that will be final and binding upon the parties. We reserve the right to reject any withdrawals that we determine are not in appropriate form or that we determine are unlawful to accept. We will accept all properly tendered Eligible Options that are not validly withdrawn. No withdrawals of options will be deemed to have been properly made until all defects or irregularities have been cured by the withdrawing option holder or waived by us. Neither we nor any other person is obligated to give notice of any defects or irregularities in tenders, nor will anyone incur any liability for failure to give any notice. This is a one-time Offer, and we will strictly enforce the election period, subject only to an extension that we may grant in our discretion.
