RAINMAKER SYSTEMS, INC. 
 WARRANT TO PURCHASE              SHARES OF 
 COMMON STOCK, PAR VALUE $0.001 PER SHARE 
 For VALUE RECEIVED,
                                        
(“Warrantholder”), is entitled to purchase, subject to the provisions of this Warrant, from Rainmaker Systems, Inc., a Delaware corporation (“Company”), at any time after the date that is six (6) months after
the date hereof (the “Exercisability Date”), but not later than 5:00 P.M., Eastern time, on the Expiration Date (as defined above), at an exercise price per share equal to $1.40 (the exercise price in effect being herein called the
“Warrant Price”),                      shares (“Warrant Shares”) of the Company’s Common Stock, par
value $0.001 per share (“Common Stock”). The number of Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time as described herein. This Warrant is the warrant
to purchase Common Stock, par value $0.001, of the Company issued pursuant to (i) Section 2 of that certain Subscription Agreement dated as of June 22, 2011 (the “Subscription Agreement”) by and between the Company and the
Warrantholder, and (ii) the Company’s registration statement on Form S-3 (file number 333-171946). 
 Section 1.
Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of this Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder. 

Section 2. Transfers. The Company shall transfer this Warrant from time to time upon the books to be maintained by the
Company for that purpose upon surrender of this Warrant for transfer, properly endorsed or accompanied by appropriate instructions for transfer in the form of Appendix A and such other documents as may be reasonably required by the Company, and a
new Warrant shall be issued to the transferee and the surrendered Warrant shall be canceled by the Company. 
 Section 3.
Exercise of Warrant. 
 (a) Subject to the provisions hereof, the Warrantholder may exercise this Warrant in whole or in
part, at any time after the Exercisability Date and prior to the expiration of the Warrant, upon surrender of the Warrant, together with delivery of the duly executed Warrant exercise form attached hereto as Appendix B (the “Exercise
Agreement”) and payment by cash, certified check or wire transfer of funds for the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any

 
business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Warrantholder). The Warrant Shares so purchased
shall be deemed to be issued to the Warrantholder or the Warrantholder’s designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered (or evidence of loss, theft or
destruction thereof and security or indemnity satisfactory to the Company), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered (such items and payment, the “Exercise Deliverables”).

 (b) On or before the third (3rd) business day following the date on which the Company has received the Exercise
Deliverables, the Company shall (i) provided that the Company’s transfer agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Warrantholder,
credit such aggregate number of shares of Common Stock to which the Warrantholder is entitled pursuant to such exercise to the Warrantholder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system,
or (ii) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the Warrantholder or, at the Warrantholder’s instruction pursuant to the Exercise Agreement, the
Warrantholder’s agent or designee, in each case, sent by reputable overnight courier to the address as specified in the applicable Exercise Agreement, a certificate, registered in the Company’s share register in the name of the
Warrantholder or its designee (as indicated in the applicable Exercise Agreement), for the number of shares of Common Stock to which the Warrantholder is entitled pursuant to such exercise. If this Warrant shall have been exercised only in part,
then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such Warrant Shares or promptly thereafter, deliver to the Warrantholder a new Warrant representing the number of shares with respect to which this
Warrant shall not then have been exercised. As used herein, “business day” means a day, other than a Saturday or Sunday, on which banks in New York City are open for the general transaction of business. 

(c) If by the third business day after such an exercise and the Company’s receipt of the Exercise Deliverables the Company fails to
deliver the required number of Warrant Shares in the manner specified herein, and if after such third business day and prior to the receipt of such Warrant Shares, the Warrantholder purchases (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a sale by the Warrantholder of the Warrant Shares which the Warrantholder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (1) pay in cash to the
Warrantholder the amount by which (x) the Warrantholder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of
Warrant Shares that the Company was required to deliver to the Warrantholder in connection with the exercise at issue by (B) the closing sale price of the Common Stock on the date of the Company’s receipt of the Exercise Deliverables and
(2) at the option of the Warrantholder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored or deliver to the Warrantholder the number of shares of Common Stock that would
have been issued had the Company timely complied with its exercise and delivery obligations hereunder; provided however, if the Company delivered all appropriate written directions and documents to its transfer agent within one business day of the
Company’s receipt of Exercise Deliverables, the foregoing Buy-In damage obligation of the Company set forth in this sentence shall not apply to such exercise. The Warrantholder shall provide the

  
 -2-

 
Company prompt written notice indicating the amounts payable to the Warrantholder in respect of the Buy-In. As used herein, “closing sale price” means the last closing trade
price for the Common Stock on the Nasdaq Global Market, as reported by Bloomberg, or, if the Nasdaq Global Market begins to operate on an extended hours basis and does not designate the closing trade price then the last trade price of the Common
Stock prior to 4:00 p.m., New York time, as reported by Bloomberg, or, if the Nasdaq Global Market is not the principal securities exchange or trading market for the Common Stock, the last closing trade price of the Common Stock on the principal
securities exchange or trading market where the Common Stock is listed or traded as reported by Bloomberg, or if the foregoing do not apply, the last closing trade price of the Common Stock in the over-the-counter market on the electronic bulletin
board for the Common Stock as reported by Bloomberg, or, if no closing trade price is reported for the Common Stock by Bloomberg, the average of the bid prices of any market makers for the Common Stock as reported in the “pink sheets” by
Pink Sheets LLC (formerly the National Quotation Bureau, Inc.). If the closing trade price cannot be calculated for the Common Stock on a particular date on any of the foregoing bases, the closing trade price of the Common Stock on such date shall
be the fair market value as mutually determined by the Company and the Warrantholder. If the Company and the Warrantholder are unable to agree upon the fair market value pursuant to the preceding sentence, the Company and the Warrantholder shall
jointly select an appraiser, who is experienced in such matters. The decision of the appraiser shall be final and conclusive, and the cost of such appraiser shall be borne equally by the Company and the Warrantholder. All of the foregoing
determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during the applicable calculation period. 
 (d) Cashless Exercise. Notwithstanding anything contained herein to the contrary, if a registration statement covering the Warrant Shares that are the subject of the Exercise Agreement is not
available for the resale of such Warrant Shares, the Warrantholder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in
payment of the aggregate Warrant Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 

 

			
	Net Number =	  	 (A x B) - (A x C)

		  	B

 For purposes of the foregoing formula: 
  

			
	A =	 	the total number of shares with respect to which this Warrant is then being exercised.
		
	B =	 	the closing sale price of the shares of Common Stock for the business day ending on the date immediately preceding the date of the Exercise Agreement.
		
	C =	 	the Warrant Price then in effect for the applicable Warrant Shares at the time of such exercise.

  
 -3-

 (e) Rule 144. For purposes of Rule 144(d) promulgated under the Securities Act of
1933, as amended, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Warrantholder, and the holding period for the Warrant Shares shall be deemed to have
commenced, on the date this Warrant was originally issued pursuant to the Subscription Agreement. 
 Section 4. Payment
of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the Warrantholder in respect of which such shares are issued, and in such case, the Company shall not
be required to issue or deliver any certificate for Warrant Shares or any Warrant until the Person requesting the same has paid to the Company the amount of such tax or has established to the Company’s reasonable satisfaction that such tax has
been paid. The Warrantholder shall be responsible for income taxes due under federal, state or other law, if any such tax is due. 
 Section 5. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and upon cancellation of
the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity with respect thereto, if requested by the Company. 

Section 6. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the
Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 6, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of
purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares
of Common Stock of the Company. 
 Section 7. Adjustments. Subject and pursuant to the provisions of this
Section 7, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter. 
 (a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding
shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock
(including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then the number of Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in effect
immediately prior to the date upon which such change shall become effective, shall be adjusted by the Company so that the Warrantholder 

  
 -4-

 
thereafter exercising the Warrant shall be entitled to receive the number of shares of Common Stock, or other capital stock which the Warrantholder would have received if the Warrant had been
exercised immediately prior to such event, upon payment of a Warrant Price that has been adjusted to reflect a fair allocation of the economics of such event to the Warrantholder. Such adjustments shall be made successively whenever any event listed
above shall occur. 
 (b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or
merger of the Company with another entity in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another entity shall be effected, then, as a condition of such
reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive upon the basis and upon the
terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange
for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken
place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Price) shall
thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, sale,
transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring
such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Warrantholder, at the last address of the Warrantholder appearing on the books of the Company, such shares of stock, securities or assets as, in
accordance with the foregoing provisions, the Warrantholder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations, reclassifications,
consolidations, mergers, sales, transfers or other dispositions. 
 (c) In case the Company shall fix a payment date for the
making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash
dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 7(a)), or subscription rights or warrants, the Warrant Price to be in effect after such payment date
shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the closing sale price per
share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company’s Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription
rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such closing sale price per share of Common Stock immediately prior to such payment date. Such adjustment shall be made
successively whenever such a payment date is fixed. 

  
 -5-

 (d) An adjustment to the Warrant Price shall become effective immediately after the payment
date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. 
 (e) In the event that, as a result of an adjustment made pursuant to this Section 7, the Warrantholder shall become entitled to receive any shares of capital stock of the Company other than shares of
Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the
Warrant Shares contained in this Warrant. 
 Section 8. Fractional Interest. No fractional shares of Common Stock
are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. 
 Section 9. Benefits. Nothing in this Warrant shall be construed to give any Person (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed
that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder. 
 Section 10.
Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company,
stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice
to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment. 

Section 11. Identity of Transfer Agent. The transfer agent for the Common Stock is Computershare Investor Services, LLC. Upon
the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will mail to the Warrantholder a
statement setting forth the name and address of such transfer agent. 
 Section 12. Notices. Unless otherwise
provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery,
(ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, and (iii) if given by mail (whether overnight courier or US mail), then such notice shall be deemed given
upon receipt of confirmation of delivery. All notices shall be addressed as follows: if to the Warrantholder, at its address as set forth in the Company’s books and records and, if to the Company, at the address as follows, or at such other
address as the Warrantholder or the Company may designate by ten days’ advance written notice to the other:

Section 13. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and
inure to the benefit of its respective successors and assigns hereunder. 
 Section 14. Governing Law; Consent to
Jurisdiction; Waiver of Jury Trial. This Warrant shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof. The Company and, by accepting this
Warrant, the Warrantholder, each irrevocably submits to the non-exclusive jurisdiction of the courts of the State of New York located in the Borough of Manhattan and the United States District Court for the Southern District of New York for the

and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES ANY RIGHT TO REQUEST
A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS WARRANT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 Section 15. Restriction on Exercise. Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Warrantholder upon any exercise of this
Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Warrantholder and its
affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the 

  
 -7-

 
Warrantholder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% of the total number of issued and outstanding shares of Common Stock (including for such
purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. By
written notice to the Company, a Warrantholder may waive the provisions of this Section 15 as to itself but any such waiver will not be effective until the 61st day after delivery thereof. 

Section 16. No Rights as Stockholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any
rights as a stockholder of the Company by virtue of its ownership of this Warrant. 
 Section 17. Amendment; Waiver.
Any term of this Warrant may be amended or waived (including the adjustment provisions included in Section 7 of this Warrant) upon the written consent of the Company and the Warrantholder. 

Section 18. Section Headings. The section headings in this Warrant are for the convenience of the Company and the
Warrantholder and in no way alter, modify, amend, limit or restrict the provisions hereof.

 Exhibit 10.1 
 RAINMAKER SYSTEMS, INC. 
 3,675,182 Shares of Common Stock, par value
$0.001 per share 
 and Warrants to Purchase up to 1,470,078 shares of Common Stock 

PLACEMENT AGENT AGREEMENT 
 June 22, 2011 
 Merriman Capital, Inc. 

135 East 57th Street 
 24th Floor

 New York, New York 10022 
 Dear Sir
or Madam: 
 Rainmaker Systems, Inc., a Delaware corporation (the “Company”), proposes to issue and sell up to
3,675,182 shares of common stock, par value $0.001 per share (the “Common Stock”) and warrants (the “Warrants”) to purchase up to 1,470,078 shares of Common Stock (collectively, the “Offered
Securities”) to one or more investors (collectively, the “Investors”). The Offered Securities are described more fully in the Registration Statement (as hereinafter defined). 

The Company hereby confirms its agreement with Merriman Capital, Inc. (the “Placement Agent”) as set forth below.

 1. Agreement to Act as Placement Agent. On the basis of the representations, warranties and agreements of the Company
herein contained and subject to all the terms and conditions of this Agreement, the Placement Agent agrees to act as the Company’s placement agent in connection with the issuance and sale, on a best efforts basis, by the Company of the Offered
Securities to the Investors. The Placement Agent shall use commercially reasonable efforts to assist the Company in obtaining performance by each Investor whose offer to purchase Offered Securities has been solicited by the Placement Agent and
accepted by the Company, but the Placement Agent shall not have any liability to the Company in the event any such purchase is not consummated for any reason. 
 (a) The Company shall pay to the Placement Agent a cash fee (the “Placement Fee”) equal to 6.5% of the gross proceeds received by the Company from the sale of the Offered Securities as
set forth on the cover page of the Prospectus (as hereinafter defined), less a credit of $25,000 representing a portion of the $35,000 cash advance previously paid by the Company to the Placement Agent. To the extent that this agreement is
terminated, such advance will be returned to the Company to the extent of out-of-pocket expenses not actually incurred by the Placement Agent. Payment of the Placement Fee with respect to the Common Stock will be paid at the Closing (as defined
below) and payment of the Placement Fee with respect to the Warrants will be paid as soon as practicable following the exercise of the Warrants. The Placement Agent may, in its discretion, retain other brokers or dealers who are members of the
Financial Industry Regulatory Authority, Inc. (“FINRA”) to act as selected dealers or subagents on such Placement Agent’s behalf in connection with the offering of the Offered Securities, payment to whom shall be solely the
responsibility of the Placement Agent retaining such selected dealer or subagent. 

 (b) The Company shall issue and sell to the Placement Agent (and/or its designees) on the
Closing Date a warrant (“Placement Agent Warrant”) for the purchase of an aggregate number of shares of Common Stock equal to 3% of the number of shares of Common Stock purchased at the Closing, having an exercise price per share
equal to 100% of the public offering price per share of Common Stock at the offering. The Placement Agent Warrant in the form attached hereto as Exhibit A shall be exercisable, in whole or in part, commencing on a date which is 181 days from
the Effective Date and expiring on the five-year anniversary of the Effective Date. The Placement Agent understands and agrees that there are significant restrictions pursuant to FINRA Rule 5110 against transferring the Placement Agent Warrant and
the underlying shares of Common Stock during the first 180 days after the Effective Date and by its acceptance thereof shall agree that it will not sell, transfer, assign, pledge or hypothecate the Placement Agent Warrant, or any portion thereof, or
be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of such securities for a period of 180 days following the Effective Date to anyone other than (i) a selected
dealer in connection with the Offering, or (ii) a bona fide officer or partner of the Placement Agent or of any such selected dealer; and only if any such transferee agrees to the foregoing lock-up restrictions. 

(c) Delivery for the Placement Agent Warrant shall be made on the Closing Date [and shall be issued in the name or names and in such
authorized denominations as the Placement Agent may request]. 
 2. Delivery and Payment. The closing (the
“Closing”) of the sale of the Offered Securities shall take place at the office of Kramer Levin Naftalis & Frankel LLP at 1177 Avenue of the Americas, New York, New York 10036 at 10:00 a.m., New York City time, on
June 24, 2011, or at such other time on such other date as may be agreed upon by the Company and the Placement Agent (the “Closing Date”). All actions taken at the Closing shall be deemed to have occurred simultaneously. On or
before the Closing Date, each Investor shall pay by wire transfer of immediately available funds to an account specified by the Company an amount equal to the product of (x) the number of Offered Securities such Investor has agreed to purchase
and (y) the purchase price per share as set forth on the cover page of the Prospectus (as defined below) (the “Purchase Amount”). On the Closing Date, the Company shall (i) deliver or cause to be delivered the Offered Securities
to the Investors, with the delivery of the Offered Securities to be made, if possible, through the facilities of The Depository Trust Company’s DWAC system, (ii) deliver or cause to be delivered the Warrants to the offices of Kramer Levin
Naftalis & Frankel LLP at 1177 Avenue of the Americas, New York, New York 10036, Attention: Richard H. Gilden, Esq. and (iii) pay to the Placement Agent the Placement Fee and the expense reimbursement to which the Placement Agent is
entitled pursuant to Section 6 hereof. 
 3. Representations and Warranties of the Company. The Company represents
and warrants and covenants to the Placement Agent that: 
 (a) The Company has prepared and filed in conformity with the
requirements of the Securities Act of 1933, as amended (the “Securities Act”), and published rules and regulations thereunder (the “Rules and Regulations”) adopted by the Securities and Exchange Commission (the
“Commission”) a “shelf” Registration Statement (as hereinafter defined) on Form S-3 (File No. 333-171946), including a base prospectus relating to the Offered Securities (the “Base Prospectus”), and
such amendments and supplements thereto as may have been required to the date of this Agreement. The term “Registration Statement” as used in this Agreement means the registration statement (including all exhibits, financial
schedules and all documents and information deemed to be a part of the Registration Statement pursuant to Rule 430A of the Rules and Regulations), as amended and/or supplemented to the date of this Agreement, including the Base Prospectus. The

Statement is effective under the Securities Act and no stop order preventing or suspending the effectiveness of the Registration Statement or suspending or preventing the use of the Prospectus
has been issued by the Commission and no proceedings for that purpose have been instituted or, to the knowledge of the Company, are threatened by the Commission. The Company, if required by the Rules and Regulations of the Commission, will file the
Prospectus (as defined below) with the Commission pursuant to Rule 424(b) of the Rules and Regulations. The term “Prospectus” as used in this Agreement means the prospectus, in the form in which it is to be filed with the Commission
pursuant to Rule 424(b) of the Rules and Regulations, or, if the prospectus is not to be filed with the Commission pursuant to Rule 424(b), the prospectus in the form included as part of the Registration Statement as of the Effective Date, except
that if any revised prospectus or prospectus supplement shall be provided to the Placement Agent by the Company for use in connection with the offering and sale of the Offered Securities which differs from the Prospectus (whether or not such revised
prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations), the term “Prospectus” shall refer to such revised prospectus or prospectus supplement, as the case may be,
from and after the time it is first provided to the Placement Agent for such use. Any preliminary prospectus or prospectus subject to completion included in the Registration Statement or filed with the Commission pursuant to Rule 424 of the Rules
and Regulations is hereafter called a “Preliminary Prospectus.” Any reference herein to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by
reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the last to occur of the Effective Date, the date of the Preliminary

Prospectus shall be deemed to refer to and include (i) the filing of any document under the Exchange Act after the Effective Date, the date of the Base Prospectus, the date of such Preliminary Prospectus or the date of the Prospectus, as the

“462(b) Registration Statement”), then any reference herein to the Registration Statement shall also be deemed to include such 462(b) Registration Statement. 
 (b) The conditions to the use of Form S-3 in connection with the offering and sale of the Offered Securities as contemplated hereby have been satisfied. The Registration Statement meets, and the offering
and sale of the Offered Securities as contemplated hereby complies with, in all material respects, the requirements of Rule 415 under the Securities Act.

Registration Statement and the Prospectus present fairly, in all material respects, the financial condition of the Company and its consolidated Subsidiaries as of the dates thereof and the results of operations, cash flows and stockholder equity at
the dates and for the periods covered thereby in conformity with generally accepted accounting principles (“GAAP”). No other financial statements, financial schedules or pro forma financial information of the Company, the
Subsidiaries or any other entity are required by the Securities Act or the Rules and Regulations to be included in the Registration Statement or the Prospectus. All disclosures contained in the Registration Statement, the Pricing Disclosure

the extent applicable. The Company and the Subsidiaries do not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations or any “variable interest entities” within the meaning of

certifications required by Sections 302 and 906 of the Sarbanes-Oxley Act with respect to all periodic reports required to be filed by it with the Commission. For purposes of the preceding sentence, “principal executive officer” and
“principal financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act.

The Company has taken all necessary actions to ensure that it is in compliance with all applicable corporate governance requirements set forth in the Nasdaq Stock Market Rules.

Company reasonably believes is adequate for their respective businesses, including, but not limited to, insurance covering all real and personal property owned or leased by the Company or the Subsidiaries against theft, damage, destruction, acts of
vandalism, all of which insurance is in full force and effect. The Company has no reason to believe that it or any of its Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or
(ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not reasonably be expected to result in a Material Adverse Effect. 

(nn) The Company has not distributed and, prior to the later to occur of the Closing Date and completion of the distribution of the
Offered Securities, will not distribute any offering material in connection with the offering and sale of the Offered Securities other than the Pricing Disclosure Materials and the Prospectus. The Company will promptly notify the Placement Agent of
any such distributions and the names of the persons receiving such distributions. 
 (oo) Each material employee benefit plan,
within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), that is maintained, administered or contributed to by the Company or any of its affiliates for employees or former
employees of the Company and the Subsidiaries has been maintained in material compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Internal Revenue Code
of 1986, as amended (the “Code”); no prohibited transaction, within the 

  
 -12-

 
meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred which would result in a material liability to the Company or any Subsidiary with respect to any such plan,
excluding transactions effected pursuant to a statutory or administrative exemption; and for each such plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no “accumulated funding
deficiency” as defined in Section 412 of the Code has been incurred, whether or not waived, and the fair market value of the assets of each such plan (excluding for these purposes accrued but unpaid contributions) exceeds the present value
of all benefits accrued under such plan determined using reasonable actuarial assumptions. 
 (pp) No relationship, direct or
indirect, exists between or among the Company or any of the Subsidiaries, on the one hand, and the directors, officers, stockholders, customers or suppliers of the Company or the Subsidiaries, on the other, which is required by the Securities Act to
be disclosed in the Registration Statement and the Prospectus and is not so disclosed. 
 (qq) The Company has not sold or
issued any securities that would be integrated with the offering of the Offered Securities contemplated by this Agreement pursuant to the Securities Act, the Rules and Regulations or the interpretations thereof by the Commission. 

(rr) Neither the Company nor any of the Subsidiaries is a party to any contract, agreement or understanding with any person (other than
this Agreement) that would give rise to a valid claim against the Company or the Subsidiaries or the Placement Agent for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Offered Securities.

 (ss) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the
Exchange Act) (a “Forward Looking Statement”) contained in the Registration Statement and the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith. 

(tt) The operations of the Company and the Subsidiaries are and have been conducted at all times in material compliance with applicable
financial record keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all jurisdictions to which the Company or the Subsidiaries are subject, the rules and
regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or
before any court or governmental agency, authority or body or any arbitrator involving the Company or any of the Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened. 

(uu) Neither the Company, nor any of the Subsidiaries, nor, to the knowledge of the Company, any director, officer, agent, employee or
other person acting on behalf of the Company or the Subsidiaries has, in the course of its actions for, or on behalf of, the Company (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses
relating to political activity, or failed to disclose fully any contribution in violation of law; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate

  
 -13-

 
funds; (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or (iv) made any unlawful bribe, rebate, payoff, influence
payment, kickback or other unlawful payment to any foreign or domestic government official or employee. 
 (vv) Based on the
financial condition of the Company as of the Closing Date after giving effect to the transactions contemplated by the Transaction Documents, (i) the Company’s fair saleable value of its assets exceeds the amount that will be required to be
paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature; (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business
through December 31, 2011 as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, and projected capital requirements and
capital availability thereof; and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be
sufficient to pay all amounts on or in respect of its debt when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash
to be payable on or in respect of its debt). 
 4. Agreements of the Company. The Company covenants and agrees with the
Placement Agent as follows: 
 (a) The Registration Statement has become effective, and if Rule 430A is used or the filing of
the Prospectus is otherwise required under Rule 424(b), the Company will file the Prospectus (properly completed if Rule 430A has been used), subject to the prior approval of the Placement Agent (which approval shall not be unreasonably withheld or
delayed), pursuant to Rule 424(b) within the prescribed time period and will provide a copy of such filing to the Placement Agent promptly following such filing. 
 (b) The Company will not, during such period as the Prospectus would be required by law to be delivered in connection with sales of the Offered Securities by an underwriter, a dealer or a placement agent
in connection with the offering contemplated by this Agreement, file any amendment or supplement to the Registration Statement or the Prospectus unless a copy thereof shall first have been submitted to the Placement Agent within a reasonable period
of time prior to the filing thereof and the Placement Agent shall not have reasonably objected thereto in good faith. 
 (c)
The Company will notify the Placement Agent promptly, and will, if requested, confirm such notification in writing, (1) when any post-effective amendment to the Registration Statement becomes effective, but only during the period mentioned in
Section 4(b); (2) of any request by the Commission for any amendments to the Registration Statement or any amendment or supplements to the Prospectus or for additional information, but only during the period mentioned in Section 4(b);
(3) of the issuance by the Commission of any stop order preventing or suspending the effectiveness of the Registration Statement or the use of any Preliminary Prospectus, the Base Prospectus, or the Prospectus, or the initiation of any
proceedings for that purpose or the threat thereof, but only during the period mentioned in Section 4(b); (4) of becoming aware of the occurrence of any event during the period mentioned in Section 4(b) that in the judgment of the
Company makes any statement made in the Registration Statement or the Prospectus untrue in any material respect or that requires the making of any changes in the Registration Statement or the Prospectus in order to make the statements therein, in

  
 -14-

 
light of the circumstances in which they are made, not misleading; and (5) of receipt by the Company of any notification with respect to any suspension of the qualification of the Offered
Securities for offer and sale in any jurisdiction. If at any time the Commission shall issue any order suspending the effectiveness of the Registration Statement in connection with the offering contemplated hereby, the Company will make every
reasonable effort to obtain the withdrawal of any such order at the earliest possible moment. If the Company has omitted any information from the Registration Statement, pursuant to Rule 430A, it will use its best efforts to comply with the
provisions of and make all requisite filings with the Commission pursuant to said Rule 430A and to notify the Placement Agent promptly of all such filings. 
 (d) If, at any time when a Prospectus relating to the Offered Securities is required to be delivered under the Securities Act, the Company becomes aware of the occurrence of any event as a result of which
the Prospectus, as then amended or supplemented, would, in the reasonable judgment of counsel to the Company or counsel to the Placement Agent, include any untrue statement of a material fact or omit to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they were made, not misleading, or the Registration Statement, as then amended or supplemented, would, in the reasonable judgment of counsel to the Company or counsel to the
Placement Agent, include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if for any other reason it is necessary, in the reasonable judgment of counsel to the
Company or counsel to the Placement Agent, at any time to amend or supplement the Prospectus or the Registration Statement to comply with the Securities Act or the Rules and Regulations, the Company will promptly notify the Placement Agent and,
subject to Section 4(b) hereof, will promptly prepare and file with the Commission, at the Company’s expense, an amendment to the Registration Statement or an amendment or supplement to the Prospectus that corrects such statement or
omission or effects such compliance and will deliver to the Placement Agent, without charge, such number of copies thereof as the Placement Agent may reasonably request. The Company consents to the use of the Prospectus or any amendment or
supplement thereto by the Placement Agent. 
 (e) To the extent not available on EDGAR, the Company will furnish to the
Placement Agent and its counsel, without charge (i) two conformed copies of the Registration Statement as originally filed with the Commission and each amendment thereto, including financial statements and schedules, and all exhibits thereto,
and (ii) so long as a prospectus relating to the Offered Securities is required to be delivered under the Securities Act, as many copies of the Prospectus or any amendment or supplement thereto as the Placement Agent may reasonably request.

 (f) The Company will comply with all the undertakings contained in the Registration Statement. 

(g) Prior to the sale of the Offered Securities to the Investors, the Company will cooperate with the Placement Agent and its counsel in
connection with the registration or qualification of the Offered Securities for offer and sale under the state securities or Blue Sky laws of such jurisdictions as the Placement Agent may reasonably request; provided, that in no event shall the
Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to general service of process in any jurisdiction where it is not now so subject.

constitute an Issuer Free Writing Prospectus. 
 (i) The Company will apply the net proceeds from the offering and sale of the
Offered Securities in the manner set forth in the Prospectus under the caption “Use of Proceeds.” 
 (j) The
Company will use its best efforts to ensure that the Offered Securities are traded on the Nasdaq Global Market at the time of the Closing. 
 (k) The Company will not at any time, directly or indirectly, take any action intended, or which might reasonably be expected, to cause or result in, or which will constitute, stabilization of the price
of the Offered Securities to facilitate the sale or resale of any of the Offered Securities. 
 (l) The Company will cause each
of its executive officers and directors, whose names are set forth in Exhibit C hereto, to furnish to the Placement Agent, on or before the Closing Date, a letter dated the date hereof, substantially in the form of Exhibit D hereto
(the “Lock-Up Agreement”). The Company will use its commercially reasonable efforts to enforce the terms of each Lock-Up Agreement and issue stop transfer instructions to the transfer agent for the shares with respect to any
transaction or contemplated transaction that would constitute a breach or default under the applicable Lock-Up Agreement. 

(m) For a period ending on the earlier of (i) 90 days after the date hereof or (ii) the termination of this Agreement by the

intention to sell, sell, contract to sell, sell any option or contract to purchase (to the extent such option or contract to purchase is exercisable within one year from the Closing Date), purchase any option or contract to sell, grant any option,
right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange

the offer and sale of any shares of Common Stock or securities convertible into or exercisable or exchangeable for shares of Common Stock or (3) enter into any swap or other agreement that transfers, in whole or in part, any of the economic
consequences of ownership of the Common Stock, whether any such transaction described in clauses (1), (2) or (3) above is to be settled by delivery of shares of Common Stock or such other securities, in cash or otherwise, without the prior
written consent of the Placement Agent (which consent may be withheld in its sole discretion), other than (i) the Offered Securities to be sold hereunder, (ii) the issuance of employee stock options or shares of restricted stock pursuant
to equity compensation plans described in the Registration Statement (excluding the exhibits thereto), the Pricing Disclosure Materials and the Prospectus, (iii) issuances of shares of Common Stock upon the exercise of options or warrants
disclosed as outstanding in the Registration Statement (excluding the exhibits thereto), the Pricing Disclosure Materials and the Prospectus or upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of
this Agreement; (iv) the issuance by the Company of any shares of Common Stock or securities convertible or exchangeable into shares of Common Stock as consideration for mergers, acquisitions, other business

subject to restrictions substantially similar to those contained in this subsection 4(m); or (v) the purchase or sale of the Company’s securities pursuant to a plan, contract or instruction that satisfies all of the requirements of Rule
10b5-1(c)(1)(i)(B) that was in effect prior to the date hereof. Notwithstanding the foregoing, for the purpose of allowing the Placement Agent to comply with FINRA Rule 2711(f)(4), if (1) during the last 17 days of the Lock-Up Period, the
Company releases earnings results or publicly announces other material news or a material event relating to the Company occurs or (2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results

announcement regarding the material news or the occurrence of the material event, as applicable, unless the Placement Agent waives such extension in writing. The Placement Agent agrees to waive such extension if the provisions of FINRA Rule
2711(f)(4) are not applicable to the Offering. The Company agrees not to accelerate the vesting of any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period, except in accordance with the terms of any
existing employment agreement.

 -21-

 
investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which it, or any of
them, may become subject under the Securities Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (i) any breach of
the representations and warranties made by the Company in Section 3 of this Agreement, (ii) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement, the Base Prospectus, any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, (B) the Pricing Disclosure Materials or any amendment or supplement thereto or (C) any application or other document, or any amendment or supplement thereto,
executed by the Company based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Offered Securities under the securities or Blue Sky laws thereof or filed with the Commission or any
securities association or securities exchange (each, an “Application”), or (iii) the omission or alleged omission to state in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus, the
Pricing Disclosure Materials or any amendment or supplement thereto, or in any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not
misleading; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises out of or is based on an untrue statement or omission or alleged untrue statement or omission
made in reliance on and in conformity with information relating to the Placement Agent furnished in writing to the Company by or on behalf of the Placement Agent expressly for inclusion in the Registration Statement, the Base Prospectus, any
Preliminary Prospectus, the Prospectus, the Pricing Disclosure Materials or any amendment or supplement thereto or in any Application (as set forth in paragraph (b) below). This indemnity agreement will be in addition to any liability which the
Company may otherwise have. 
 (b) The Placement Agent will indemnify and hold harmless the Company, each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the
foregoing indemnity from the Company to the Placement Agent, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance
on and in conformity with information relating to the Placement Agent furnished in writing to the Company by or any behalf of such Placement Agent expressly for use in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the
Prospectus or the Pricing Disclosure Materials or any amendment or supplement thereto or in any Application. This indemnity agreement will be in addition to any liability that the Placement Agent might otherwise have. The Company acknowledges that,
for all purposes under this Agreement, the name of the Placement Agent and the paragraph relating to the Placement Agent’s fees and reimbursement of expenses under the heading “Plan of Distribution” in the Prospectus,
constitute the only information relating to the Placement Agent furnished in writing to the Company by the Placement Agent expressly for inclusion in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Prospectus or the
Pricing Disclosure Materials. 
 (c) Any party that proposes to assert the right to be indemnified under this Section 8
will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify each such indemnifying party of the
commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this
Section 8 unless, and only to the extent that, the indemnifying party has been materially prejudiced by such omission. If any such action is 

  
 -22-

 
brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by
delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with
counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal
or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party,
(2) the indemnified party has reasonably concluded (based on advice of counsel) that a conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party that would prevent the counsel
selected by the indemnifying party from representing the indemnified party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (3) the indemnifying party has
not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at
the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements
and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party
promptly as they are incurred. The indemnifying party will not, without the prior written consent of the indemnified party (which consent will not be unreasonably withheld or delayed), settle or compromise or consent to the entry of any judgment in
any pending or threatened claim, action, suit or proceeding in respect of which indemnification has been sought hereunder, unless such settlement, compromise or consent includes an unconditional release of the indemnified party and each such
controlling person from all liability arising out of such claim, action, suit or proceeding. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be
unreasonably withheld). 
 (d) In order to provide for just and equitable contribution in circumstances in which the
indemnification provided for in the foregoing paragraphs of this Section 8 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Placement Agent, the Company and the Placement Agent will
contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any
claim asserted, but after deducting any contribution received by the Company from persons other than the Placement Agent such as persons who control the Company within the meaning of the Securities Act or the Exchange Act, officers of the Company
who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and the Placement Agent may be subject in such proportion as shall be appropriate to reflect the relative benefits
received by the Company on the one hand and the Placement Agent on the other. The relative benefits received by the Company on the one hand and the Placement Agent on the other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting Company expenses) received by the Company as set forth in the table on the cover page of the Prospectus bear to the fee received by such Placement Agent hereunder. If, but only if, the allocation provided by the
foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the

  
 -23-

 
relative fault of the Company, on the one hand, and the Placement Agent, on the other, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or
damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information supplied by the Company or the Placement Agent, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Placement Agent agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation which does
not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this
Section 8(d) shall be deemed to include, for purpose of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding
the provisions of this Section 8(d), the Placement Agent shall not be required to contribute any amount in excess of the fee received by it, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8(d), any person who controls a party to this Agreement within the meaning of the
Securities Act or the Exchange Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the
provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 8(d), will notify any such
party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 8(d). No party will
be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld). 
 9. Termination. 
 (a) The obligations of the Placement Agent under this
Agreement may be terminated at any time prior to the Closing Date, by notice to the Company from the Placement Agent, without liability on the part of the Placement Agent to the Company if, prior to delivery and payment for the Offered Securities,
in the sole judgment of the Placement Agent (i) trading in the Common Stock of the Company shall have been suspended by the Commission or by Nasdaq Global Market, (ii) trading in securities generally on the New York Stock Exchange, Nasdaq
or AMEX or in the over-the-counter market shall have been suspended or limited or minimum or maximum prices shall have been generally established on any of such exchange or additional material governmental restrictions, not in force on the date of
this Agreement, shall have been imposed upon trading in securities generally by any of such exchange or by order of the Commission or any court or other governmental authority, (iii) a general banking moratorium shall have been declared by
Federal or New York State authorities, or (iv) any material adverse change in the financial or securities markets in the United States or any outbreak or material escalation of hostilities or declaration by the United States of a national
emergency or war or other calamity or crisis shall have occurred, the effect of any of which is such as to make it, in the sole judgment of the Placement Agent, impracticable or inadvisable to market the Offered Securities on the terms and in the
manner contemplated by the Prospectus. 
 (b) If this Agreement shall be terminated pursuant to any of the provisions hereof,
or if the sale of the Offered Securities provided for herein is not consummated because any 

  
 -24-

 
condition to the obligations of the Placement Agent set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or
comply with any provision hereof, the Company will, subject to demand by the Placement Agent, reimburse the Placement Agent for all out-of-pocket expenses incurred in connection herewith, subject to the limitation in Section 6. 

10. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Offered Securities
or any other services the Placement Agent may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by
the Placement Agent: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Placement Agent, on the other, exists; (ii) the Placement Agent is not acting as an advisor, expert or
otherwise, to the Company, including, without limitation, with respect to the determination of the offering price of the Offered Securities, and such relationship between the Company, on the one hand, and the Placement Agent, on the other, is
entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Placement Agent may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the
Placement Agent and its affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Placement Agent with respect to any breach of fiduciary duty in connection with
this offering. 
 11. Notices. Notice given pursuant to any of the provisions of this Agreement shall
be in writing and, unless otherwise specified, shall be mailed or delivered (a) if to the Company, at the office of the Company, 900 East Hamilton Avenue, Suite 400, Campbell, California 95008, Attention: Timothy Burns, Chief Financial Officer,

set forth in Sections 6 and 8 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

 COMMON STOCK PURCHASE WARRANT 

For the Purchase of 
              shares of Common Stock 
 of 
 Rainmaker System, Inc. 

1. Purchase Warrant. 
 THIS CERTIFIES THAT, in consideration of $1.00 duly paid by or on behalf of Merriman Capital, Inc. (“Holder”), as the registered owner of this Common Stock Purchase Warrant
(“Purchase Warrant”), to Rainmaker Systems, Inc. (the “Company”), Holder is entitled, at any time or from time to time from six months from the date of the effective date of the offering in connection with which
this purchase warrant is being issued or [            ], 2011 (the “Commencement Date”), and at or before 5:00 p.m. Eastern Time on the five year anniversary of the
effective date of the offering, or             , 2016 (the “Expiration Date”), but not thereafter, to subscribe for, purchase and receive, in whole or in part, up to
                     shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (“Common
Stock”) subject to adjustment as provided in Section 5 hereof. If the Expiration Date is a day 

 
on which banking institutions are authorized by law to close, then this Purchase Warrant may be exercised on the next succeeding day which is not such a day in accordance with the terms herein.
During the period commencing on the Commencement Date and ending on the Expiration Date, the Company agrees not to take any action that would terminate the Purchase Warrant. This Purchase Warrant is initially exercisable at
$             per Share so purchased (a price equal to 100% of the public offering price per share of common stock at the offering in connection with which this purchase warrant is
being issued); provided, however, that upon the occurrence of any of the events specified in Section 5 hereof, the rights granted by this Purchase Warrant, including the exercise price per Share and the number of Shares to be received upon such
exercise, shall be adjusted as therein specified. The term “Exercise Price” shall mean the initial exercise price or the adjusted exercise price, depending on the context. 

2. Exercise. 
 2.1 Exercise Form. In order to exercise this Purchase Warrant, the exercise form attached hereto must be duly executed and completed and delivered to the Company, together with this Purchase
Warrant and payment of the Exercise Price for the Shares being purchased payable in cash (unless exercised pursuant to the terms of Section 2.3 below) by wire transfer of immediately available funds to an account designated by the Company or by
certified check or official bank check. If the subscription rights represented hereby shall not be exercised at or before 5:00 p.m., Eastern time, on the Expiration Date, this Purchase Warrant shall become and be void without further force or
effect, and all rights represented hereby shall cease and expire. 
 2.2 Legend. Each certificate for the securities
purchased under this Purchase Warrant shall bear a legend as follows unless such securities have been registered under the Securities Act: 

“The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the “Act”),
or applicable state law. Neither the securities nor any interest therein may be offered for sale, sold or otherwise transferred except pursuant to an effective registration statement under the Act, or pursuant to an exemption from registration under
the Act and applicable state law.” 
 2.3 Cashless Exercise. 

2.3.1 Determination of Amount. In lieu of the payment of the Exercise Price multiplied by the number of Shares which this
Purchase Warrant is exercisable in the manner required by Section 2.1, the Holder shall have the right (but not the obligation) to convert any exercisable but unexercised portion of this Purchase Warrant into Shares (“Conversion
Right”) as follows: upon exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Exercise Price in cash) that number of Shares equal to the quotient obtained by dividing
(x) the “Value” (as defined below) of the portion of the Purchase Warrant being converted by (y) the Current Market Price per Share (as defined below). The “Value” of the portion of the Purchase Warrant being
converted shall equal the remainder derived from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of Shares underlying the portion of this Purchase Warrant being converted from (b) the Current Market Price of
a Share multiplied by the number of Shares underlying the portion of the Purchase Warrant being converted. As used herein, the term “Current Market Price” per Share at any date shall mean (i) if the Shares are listed on a
national securities exchange or quoted on the Nasdaq Global Market, Nasdaq Capital Market or NASD OTC Bulletin Board (or successor exchange), the last sale price of the Shares in the principal trading market for the Shares as reported by the
exchange, Nasdaq or the NASD, as the case may be, on the last trading day preceding the date in question; (ii) if the Shares are not listed on a national securities exchange or quoted on the Nasdaq Global Market, Nasdaq Capital Market or the
NASD OTC Bulletin Board (or successor exchange), but is traded in the residual over-the-counter 

 
market, the closing bid price for the Shares on the last trading day preceding the date in question for which such quotations are reported by the Pink Sheets, LLC or similar publisher of such
quotations; and (iii) if the fair market value of the Shares cannot be determined pursuant to clause (i) or (ii) above, such price as the Board of Directors of the Company shall determine, in good faith. 

2.3.2 Mechanics of Cashless Exercise. The cashless exercise right may be exercised by the Holder on any business day on
or after the Commencement Date and not later than the Expiration Date by delivering the Purchase Warrant with the duly executed exercise form attached hereto with the cashless exercise section completed to the Company, exercising the cashless
exercise right and specifying the total number of Shares the Holder will purchase pursuant to such cashless exercise right. 

3. Transfer. 
 3.1 General Restrictions. The registered Holder of this Purchase Warrant agrees by his, her or its acceptance hereof, that such Holder will not: (a) sell, transfer, assign, pledge or
hypothecate this Purchase Warrant for a period of one hundred eighty days (180 days) following the effective date of the offering to anyone other than: (i) a selected dealer participating in the offering of securities which this Purchase
Warrant is being issued in connection with, or (ii) a bona fide officer of the Holder or of any selected dealer, in each case in accordance with FINRA Rule 5110(g)(1) or (b) cause this Purchase Warrant or the securities issuable hereunder
to be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of this Purchase Warrant or the securities hereunder, except as provided for in FINRA Rule 5110(g)(2). On and
after one hundred eighty days (180 days) following the effective date of the offering, transfers to others may be made subject to compliance with or exemptions from applicable securities laws. In order to make any permitted assignment, the Holder
must deliver to the Company the assignment form attached hereto duly executed and completed, together with the Purchase Warrant and payment of all transfer taxes, if any, payable in connection therewith. The Company shall, within five
(5) business days, transfer this Purchase Warrant on the books of the Company and shall execute and deliver a new Purchase Warrant or Purchase Warrants of like tenor to the appropriate assignee(s) expressly evidencing the right to purchase the
aggregate number of Shares purchasable hereunder or such portion of such number as shall be contemplated by any such assignment. 
 3.2 Restrictions Imposed by the Act. The securities evidenced by this Purchase Warrant shall not be transferred unless and until: (i) the Company has received the opinion of counsel for
the Holder that the securities may be transferred pursuant to an exemption from registration under the Act and applicable state securities laws, the availability of which is established to the reasonable satisfaction of the Company, or (ii) a
registration statement or a post-effective amendment to the registration statement relating to the offer and sale of such securities has been filed by the Company and declared effective by the Securities and Exchange Commission (the
“Commission”) and compliance with applicable state securities law has been established. 
 3.3 Holder
Representations. The Holder hereby represents and warrants to the Company as follows: 
 3.3.1. This Warrant and the
securities to be acquired upon exercise of this Warrant by Holder will be acquired for investment for Holder’s account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act.

 3.3.2. Holder has received or has had full access to all the information it considers necessary or appropriate to make an
informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask 

 
questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information necessary to
verify any information furnished to Holder or to which Holder has access. 
 3.3.3. Holder understands that the purchase of
this Warrant and its underlying securities involves substantial risk. Holder has experience as an investor in securities of companies similar to the Company and acknowledges that Holder can bear the economic risk of such Holder’s
investment in this Warrant and its underlying securities and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this Warrant and its underlying securities
and/or has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial
circumstances of such persons. 
 3.3.4. Holder is an “accredited investor” within the meaning of Regulation D
promulgated under the Act. 
 4. New Purchase Warrant to be Issued. 

4.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3 hereof, this Purchase Warrant may be
exercised or assigned in whole or in part. In the event of the exercise or assignment hereof in part only, upon surrender of this Purchase Warrant for cancellation, together with the duly executed exercise or assignment form and funds sufficient to
pay any Exercise Price and/or transfer tax if exercised pursuant to Section 2.1 hereto, the Company shall cause to be delivered to the Holder without charge a new Purchase Warrant of like tenor to this Purchase Warrant in the name of the Holder
evidencing the right of the Holder to purchase the number of Shares purchasable hereunder as to which this Purchase Warrant has not been exercised or assigned. 
 4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Purchase Warrant and of reasonably satisfactory
indemnification or the posting of a bond, the Company shall execute and deliver a new Purchase Warrant of like tenor and date. Any such new Purchase Warrant executed and delivered as a result of such loss, theft, mutilation or destruction shall
constitute a substitute contractual obligation on the part of the Company. 
 5. Adjustments. 

5.1 Adjustments to Exercise Price and Number of Shares. The Exercise Price and the number of Shares underlying the Purchase
Warrant shall be subject to adjustment from time to time as hereinafter set forth: 
 5.1.1 Stock Dividends; Split
Ups. If after the date hereof, and subject to the provisions of Section 5.3 below, the number of outstanding shares of Common Stock of the Company is increased by a stock dividend payable in shares or by a split up of shares or other
similar event, then, on the effective day thereof, the number of Shares of the Company purchasable hereunder shall be increased in proportion to such increase in outstanding shares of Common Stock and the Exercise Price in effect immediately prior
to such event will be proportionally reduced. 
 5.1.2 Aggregation of Shares. If after the date hereof, and subject
to the provisions of Section 5.3, the number of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, on

 
the effective date thereof, the number of Shares purchasable hereunder shall be decreased in proportion to such decrease in outstanding shares of Common Stock and the Exercise Price in effect
immediately prior to such event will be proportionally increased. 
 5.1.3 Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock other than a change covered by Section 5.1.1 or 5.1.2 hereof or that solely affects the par value of such shares, or in the
case of any share reconstruction or amalgamation or consolidation of the Company with or into another corporation (other than a consolidation or share reconstruction or amalgamation in which the Company is the continuing corporation and that does
not result in any reclassification or reorganization of the outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially as an entirety
in connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have the right thereafter (until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same
aggregate Exercise Price payable hereunder immediately prior to such event, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, share reconstruction or
amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a holder of the number of Shares obtainable upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also
results in a change in Shares covered by Section 5.1.1 or 5.1.2, then such adjustment shall be made pursuant to Sections 5.1.1, 5.1.2 and this Section 5.1.3. The provisions of this Section 5.1.3 shall similarly apply to successive
reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers. 

5.1.4 Changes in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant
to this Section, and any Purchase Warrant issued after such change may state the same Exercise Price and the same number of Shares as are stated in any Purchase Warrant initially issued. The acceptance by any Holder of the issuance of a new Purchase
Warrant reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring after the Commencement Date or the computation thereof. 
 5.2 Substitute Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company with or into, another corporation (other than a
consolidation or share reconstruction or amalgamation which does not result in any reclassification or change of the outstanding Shares), the corporation formed by such consolidation or share reconstruction or amalgamation shall execute and deliver
to the Holder a supplemental Purchase Warrant providing that the holder of each Purchase Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Warrant) to receive, upon exercise
of such Purchase Warrant, the kind and amount of shares of stock and other securities and property receivable upon such consolidation or share reconstruction or amalgamation, by a holder of the number of Shares for which such Purchase Warrant might
have been exercised immediately prior to such consolidation, share reconstruction or amalgamation, sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which shall be identical to the adjustments provided in
Section 5.1. The above provision of this Section shall similarly apply to successive consolidations or share reconstructions or amalgamations. 
 5.3 Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares upon the exercise of this Purchase Warrant, nor shall it be
required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the case may be, to the nearest whole number of
Shares or other securities, properties or rights. 

 6. Reservation. The Company shall at all times reserve and keep available out of
its authorized shares of Common Stock, solely for the purpose of issuance upon exercise of the Purchase Warrant or any substitute Purchase Warrant issued pursuant to Section 5, such number of Shares or other securities, properties or rights as
shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of the Purchase Warrant and payment of the Exercise Price therefor, in accordance with the terms hereby, all Shares and other securities issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any stockholder.
 7. Piggyback Registration Rights. If the Company at any time after the Commencement Date proposes to file a registration statement under the Securities Act registering shares of its common stock,
whether for sale for the account of the Company or for the account of any holder of securities of the Company, the Company will provide written notice to the Holder at least fifteen (15) days prior to the anticipated filing date of its
intention to file such registration statement. If within five (5) days after receipt of such notice the Holder provides a written request to the Company specifying the Shares that the Holder requests be included in the registration statement,
the Company will use commercially reasonable efforts to include in the registration statement the Shares so requested by the Holder. Notwithstanding the foregoing, (i) the notice and registration rights of this section shall not apply to any
registration statement on Form S-4, Form S-8, or any similar form, (ii) the Company may at any time prior to the effective date of the registration statement determine for any reason not to register or to delay registration of such securities,
and (iii) if an underwriter or placement agent advises the Company that, in its opinion, the inclusion of the Shares in the registration statement would materially impair the marketability of any such offering, the Company may exclude from the

Section 4(n) of the Placement Agent Agreement), (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant
to purchase, or otherwise transfer or dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission in respect of, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for shares of Common Stock (including without limitation, shares of Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the

in accordance with the terms of any existing employment agreement. In furtherance of the foregoing, the Company, and any duly appointed transfer agent or depositary for the registration or transfer of the securities described herein, are hereby
authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement. 
 The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a sale or
disposition of shares of Common Stock even if such securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of
any right (including without limitation any put option or put equivalent position or call option or call equivalent position) with respect to any of the shares of Common Stock or with respect to any security that includes, relates to, or derives any
significant part of its value from such shares. 
 The undersigned hereby represents and warrants that the undersigned has full
power and authority to enter into this Lock-Up Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the
undersigned. 
 The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s
transfer agent and registrar or depositary against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions. 
 The undersigned understands that, if the Placement Agent Agreement does not become effective, or if the Placement Agent Agreement (other than the provisions thereof which survive termination) shall
terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder, the undersigned shall be released from all obligations under this Lock-Up Agreement. 

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the
conflict of laws principles thereof.
