any Committee designated by the Board to administer the Plan pursuant to Section 15.

that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change in

Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause, if any
Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires
(or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets 







 
from the Company that have a total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately
prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection, the following will not constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity

absence that the Employer approves. Where the period of leave exceeds three (3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have
terminated three (3) months and one (1) day following the commencement of such leave. The Administrator, in its discretion, from time to time may, prior to an Offering Date for all options to be granted on such Offering Date, determine (on
a uniform and nondiscriminatory basis) that the definition of Eligible Employee will or will not include an individual if he or she: (i) has not completed at least two (2) years of service since his or her last hire date (or such lesser

 -4-









 
Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such

purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate which exceeds twenty-five thousand dollars ($25,000) worth of stock
(determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time. 
 4. Offering Periods. The Plan will be implemented by twelve (12) month Offering Periods with a new Offering Period commencing every six (6) months on the first Trading Day on or after
August 15 and February 15 each year, or on such other date as the Administrator will determine. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to
future offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter. 
 5. Participation. An Eligible Employee may participate in the Plan by (i) submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Administrator
prior to an applicable Offering Date, a properly completed subscription agreement authorizing payroll deductions in the form provided by the Administrator for such purpose (which may be similar to the form attached hereto as Exhibit A), or
(ii) following an electronic or other enrollment procedure prescribed by the Administrator. 
 6. Payroll
Deductions. 
 (a) At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have
payroll deductions made on each pay day during the Offering Period in an amount not exceeding ten percent (10%) of the Compensation which he or she receives on each pay day during the Offering Period. A Participant’s subscription agreement
will remain in effect for successive Offering Periods unless terminated as provided in Section 11 hereof. 
 (b) Payroll
deductions for a Participant will commence on the first pay day following the Offering Date and will end on the last pay day prior to the applicable Exercise Date of such Offering Period to which such authorization is applicable, unless sooner
terminated by the Participant as provided in Section 11 hereof. 
 (c) All payroll deductions made for a Participant will
be credited to his or her account under the Plan and will be withheld in whole percentages only. A Participant may not make any additional payments into such account. 
 (d) A Participant may discontinue his or her participation in the Plan as provided in Section 11. If permitted by the Administrator, as determined in its sole discretion, for an Offering Period, a
Participant may increase or decrease the rate of his or her payroll deductions during the Offering Period by (i) properly completing and submitting to the Company’s payroll office (or its


  
 -5-









 
designee), on or before a date prescribed by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in payroll deduction rate in the form
provided by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the Administrator. If a Participant has not followed such procedures to change the rate of payroll deductions, the rate of his or
her payroll deductions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless terminated as provided in Section 11). The Administrator may, in its sole discretion, limit the nature and/or
number of payroll deduction rate changes that may be made by Participants during any Offering Period. Any change in payroll deduction rate made pursuant to this Section 6(d) will be effective as of the first full payroll period following five
(5) business days after the date on which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in payroll deduction rate more quickly). 

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(c), a
Participant’s payroll deductions may be decreased to zero percent (0%) at any time during an Exercise Period. Subject to Section 423(b)(8) of the Code and Section 3(c) hereof, payroll deductions will recommence at the rate originally
elected by the Participant effective as of the beginning of the first Exercise Period which is scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 11. 

(f) At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is
disposed of, the Participant must make adequate provision for the Company’s or Employer’s federal, state, or any other tax liability payable to any authority, national insurance, social security or other tax withholding obligations, if
any, which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the
Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock by the
Eligible Employee. 
 7. Grant of Option. On the Offering Date of each Offering Period, each Eligible Employee
participating in such Offering Period will be granted an option to purchase on each Exercise Date with respect to an Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible
Employee’s payroll deductions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be
permitted to purchase during each Offering Period more than 1,000 shares of the Common Stock (subject to any adjustment pursuant to Section 20), and provided further that such purchase will be subject to the limitations set forth in
Sections 3(c) and 14. The Eligible Employee may accept the grant of such option with respect any future Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5(b). The
Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Offering Period. Exercise of the option will occur as
provided in Section 8, unless the Participant has withdrawn pursuant to Section 11. The option will expire on the last day of the Offering Period. 

  
 -6-









 8. Exercise of Option. 

(a) Unless a Participant withdraws from the Plan as provided in Section 11, his or her option for the purchase of shares of Common
Stock will be exercised automatically on each Exercise Date of the Offering Period, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated payroll
deductions in his or her account. No fractional shares of Common Stock will be purchased; any payroll deductions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the
Participant’s account for the subsequent Offering Period, subject to earlier withdrawal by the Participant as provided in Section 11. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the
Participant. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her. 
 (b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of
Common Stock that were available for sale under the Plan on the Offering Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its
sole discretion provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Offering Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will
determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or terminate all Offering Periods then in effect pursuant to
Section 21. The Company may make a pro rata allocation of the shares available on the Offering Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under
the Plan by the Company’s stockholders subsequent to such Offering Date. 
 9. Delivery. As soon as reasonably
practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares purchased upon exercise of his or her option in a form determined by the Administrator
(in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may
utilize electronic or automated methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying
dispositions of such shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the
Participant as provided in this Section 9. 

  
 -7-









 10. Automatic Transfer To Low Price Offering Period. In the event that the Fair
Market Value of a share of Common Stock is lower on an Exercise Date than it was on the Offering Date for that Offering Period, all employees participating in the plan on such Exercise Date shall be deemed to have withdrawn from the Offering Period
immediately after the exercise of their option on such Exercise Date and to have enrolled as participants in the newly commencing Offering Period. A participant may elect to remain in the previous Offering Period by filing a written statement
declaring such election with the Company prior to the time of the automatic change to the new Offering Period. 
 11.
Withdrawal. 
 (a) A Participant may withdraw all but not less than all the payroll deductions credited to his or her
account and not yet used to exercise his or her option under the Plan at any time by (i) submitting to the Company’s payroll office (or its designee) a written notice of withdrawal in the form prescribed by the Administrator for such
purpose (which may be similar to the form attached hereto as Exhibit B), or (ii) following an electronic or other withdrawal procedure prescribed by the Administrator. All of the Participant’s payroll deductions credited to his
or her account will be paid to such Participant promptly after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further payroll deductions for the purchase of shares
will be made for such Offering Period. If a Participant withdraws from an Offering Period, payroll deductions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the
provisions of Section 5. 
 (b) A Participant’s withdrawal from an Offering Period will not have any effect upon his
or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods, which commence after the termination of the Offering Period from which the Participant withdraws. 

12. Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be
deemed to have elected to withdraw from the Plan and the payroll deductions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such
Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 16, and such Participant’s option will be automatically terminated. 

13. Interest. No interest will accrue on the payroll deductions of a Participant in the Plan. 

14. Stock. 
 (a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 20 hereof, the maximum number of shares of Common Stock which will be made available for sale under the
Plan will be 900,000 shares, plus an annual increase to be added on the first day of each Fiscal Year beginning with the 2012 Fiscal Year, equal to the least of (i) 1,500,000 shares of Common Stock, (ii) one percent (1%) of the
outstanding shares of Common Stock on the last day of the immediately preceding fiscal year, or (iii) an amount determined by the Administrator. 

  
 -8-









 (b) Until the shares are issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist
with respect to such shares. 
 (c) Shares of Common Stock to be delivered to a Participant under the Plan will be registered in
the name of the Participant or in the name of the Participant and his or her spouse. 
 15. Administration. The Plan will
be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms
of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.
Notwithstanding any provision to the contrary in this Plan, the Administrator may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures for
jurisdictions outside of the United States. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling
of payroll deductions, making of contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold payroll deductions, payment of interest, conversion of local
currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates which vary with local requirements. 

16. Designation of Beneficiary. 
 (a) A Participant may file a designation of a beneficiary who is to receive any shares of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such
Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In addition, a Participant may file a designation of a beneficiary who is to receive any cash
from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such
designation to be effective. 
 (b) Such designation of beneficiary may be changed by the Participant at any time by notice in a
form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such shares
and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the
spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

  
 -9-









 (c) All beneficiary designations will be in such form and manner as the Administrator may
designate from time to time. 
 17. Transferability. Neither payroll deductions credited to a Participant’s account
nor any rights with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as
provided in Section 16 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period
in accordance with Section 11 hereof. 
 18. Use of Funds. The Company may use all payroll deductions received or
held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such payroll deductions. Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to
such shares. 
 19. Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of
account will be given to participating Eligible Employees at least annually, which statements will set forth the amounts of payroll deductions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if
any. 
 20. Adjustments, Dissolution, Liquidation, Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities,
or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the
corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may
deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised, and the
numerical limits of Sections 7 and 14. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, any Exercise Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by
the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing, at least ten (10) business days prior to the New Exercise
Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has
withdrawn from the Offering Period as provided in Section 11 hereof. 

  
 -10-









 (c) Merger or Change in Control. In the event of a merger or Change in Control, each
outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option,
the Exercise Period with respect to which such option relates will be shortened by setting a New Exercise Date and will end on the New Exercise Date. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in
Control. The Administrator will notify each Participant in writing prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be
exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 11 hereof. 
 21. Amendment or Termination. 
 (a) The Administrator, in its sole
discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately
or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in
accordance with their terms (and subject to any adjustment pursuant to Section 20). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts which have not been used to purchase shares
of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under local laws) as soon as administratively practicable. 
 (b) Without stockholder consent and without limiting Section 21(a), the Administrator will be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount
withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or
mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock
for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with
the Plan. 
 (c) In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable
financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to: 

(i) amending the Plan to conform with the safe harbor definition under Financial Accounting Standards Board Accounting Standards
Codification Topic 718, including with respect to an Offering Period underway at the time; 

  
 -11-









 (ii) altering the Purchase Price for any Offering Period including an Offering Period
underway at the time of the change in Purchase Price; 
 (iii) shortening any Offering Period by setting a New Exercise Date,
including an Offering Period underway at the time of the Administrator action; 
 (iv) reducing the maximum percentage of
Compensation a Participant may elect to set aside as payroll deductions; and 
 (v) reducing the maximum number of Shares a
Participant may purchase during any Offering Period. 
 Such modifications or amendments will not require stockholder approval
or the consent of any Plan Participants. 
 22. Notices. All notices or other communications by a Participant to the
Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

23. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of
such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance. 

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the
time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the

             Change in Payroll Deduction Rate 

             Change of Beneficiary(ies) 

1.              hereby elects to participate in the ServiceSource
International, Inc. 2011 Employee Stock Purchase Plan, as amended and restated (the “Plan”) and subscribes to purchase shares of the Company’s Common Stock in accordance with this Subscription Agreement and the Plan.

 2. I hereby authorize payroll deductions from each paycheck in the amount of
            % of my Compensation on each payday (from 0 to 10%) during the Offering Period in accordance with the Plan. (Please note that no fractional percentages are permitted.)
For the first Offering Period under the Plan, this will only apply to remaining paydays during the first Offering Period. 
 3.
I understand that said payroll deductions will be accumulated for the purchase of shares of Common Stock at the applicable Purchase Price determined in accordance with the Plan. I understand that if I do not withdraw from an Offering Period, any
accumulated payroll deductions will be used to automatically exercise my option and purchase Common Stock under the Plan. 
 4.
I have received a copy of the complete Plan and its accompanying prospectus. I understand that my participation in the Plan is in all respects subject to the terms of the Plan. 

5. Shares of Common Stock purchased for me under the Plan should be issued in the name(s) of
             (Eligible Employee or Eligible Employee and Spouse only). 
 6. I understand that if I dispose of any shares received by me pursuant to the Plan within two (2) years after the Offering Date (the first day of the Offering Period during which I purchased such
shares) or one (1) year after the Exercise Date, I will be treated for federal income tax purposes as having received ordinary income at the time of such disposition in an amount equal to the excess of the fair market value of the shares at the
time such shares were purchased by me over the price that I paid for the shares. I hereby agree to notify the Company in writing within thirty (30) days after the date of any disposition of my shares and I will make adequate provision for
Federal, state or other tax withholding obligations, if any, which arise upon the disposition of the Common Stock. The Company may, but will not be obligated to, withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to 







 
make available to the Company any tax deductions or benefits attributable to sale or early disposition of Common Stock by me. If I dispose of such shares at any time after the expiration of the
two (2)-year and one (1)-year holding periods, I understand that I will be treated for federal income tax purposes as having received income only at the time of such disposition, and that such income will be taxed as ordinary income only to the
extent of an amount equal to the lesser of (a) the excess of the fair market value of the shares at the time of such disposition over the purchase price which I paid for the shares, or (b) 15% of the fair market value of the shares on the
first day of the Offering Period. The remainder of the gain, if any, recognized on such disposition will be taxed as capital gain. 
 7. I hereby agree to be bound by the terms of the Plan. The effectiveness of this Subscription Agreement is dependent upon my eligibility to participate in the Plan. 

8. In the event of my death, I hereby designate the following as my beneficiary(ies) to receive all payments and shares due me under the
Plan:
