▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

Rainmaker Systems, Inc., a Delaware corporation (the “Company”), proposes to issue and sell 3,500,000 shares (the “Company Firm Shares”) of the Company’s Common Stock, $0.001 par value per share (the “Common Stock”), and the stockholders of the Company named in Schedule I hereto (the “Selling Stockholders”) propose to sell an aggregate of 665,690 shares (the “Selling Stockholder Firm Shares”) of Common Stock, in each case to you and to the several other Underwriters named in Schedule II hereto (collectively, the “Underwriters”), for whom you are acting as representatives (collectively, the “Representatives”). The Company has also agreed to grant to you and the other Underwriters an option (the “Option”) to purchase up to an additional 624,853 shares of Common Stock, on the terms and for the purposes set forth in Section 1(b) (the “Option Shares”). The Company Firm Shares and the Selling Stockholder Firm Shares are referred to collectively herein as the “Firm Shares,” and the Firm Shares and the Option Shares are referred to collectively herein as the “Shares.”

The Company and each of the Selling Stockholders confirm as follows their respective agreements with the Representatives and the several other Underwriters.

1. Agreement to Sell and Purchase.

(a) On the basis of the representations, warranties and agreements of the Company and the Selling Stockholders herein contained and subject to all the terms and conditions of this Agreement, (i) the Company agrees to issue and sell the Company Firm Shares to the several Underwriters, (ii) each Selling Stockholder, severally and not jointly, agrees to sell to the several Underwriters the respective number of Selling Stockholder Firm Shares set forth opposite that Selling Stockholder’s name on Schedule I hereto and (iii) each of the Underwriters, severally and not jointly, agrees to purchase from the Company and the Selling Stockholders the respective number of Firm Shares set forth opposite that Underwriter’s name in Schedule II hereto (as adjusted by the

¹	Plus an option to purchase up to an additional 624,853 shares to cover over-allotments.

Representatives in such manner as they deem advisable to avoid fractional shares), at the purchase price of $8.022 for each Firm Share. The number of Firm Shares to be purchased by each Underwriter from the Company and each Selling Stockholder shall be as nearly as practicable in the same proportion to the total number of Firm Shares being sold by the Company and each Selling Stockholder as the number of Firm Shares being purchased by each Underwriter bears to the total number of Firm Shares to be sold hereunder.

(b) Subject to all the terms and conditions of this Agreement, the Company grants the Option to the several Underwriters to purchase, severally and not jointly, up to the maximum number of Option Shares at the same price per share as the Underwriters shall pay for the Firm Shares. The Option may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters and may be exercised in whole or in part at any time (but not more than once) on or before the 30th day after the date of this Agreement upon written (including fax or email) notice in accordance with Section 12 below (the “Option Shares Notice”) by the Representatives to the Company no later than 12:00 noon, New York City time, at least two and no more than five business days before the date specified for closing in the Option Shares Notice (the “Option Closing Date”), setting forth the aggregate number of Option Shares to be purchased and the time and date for such purchase. On the Option Closing Date, the Company will issue and sell to the Underwriters the number of Option Shares set forth in the Option Shares Notice, and each Underwriter will purchase such percentage of the Option Shares as is equal to the percentage of Firm Shares that such Underwriter is purchasing, as adjusted by the Representatives in such manner as they deem advisable to avoid fractional shares.

2. Delivery and Payment. Delivery of the Firm Shares shall be made to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment by the Underwriters of the purchase price by wire transfer payable in same-day funds to the order of the Company for the Company Firm Shares to be sold by it and to U.S. Stock Transfer Corporation, as custodian for the Selling Stockholders (the “Custodian”) for the Firm Shares to be sold by the Selling Stockholders at the office of ▇▇▇▇▇▇▇ & Company, LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, at 10:00 a.m., New York City time, on the third (or, if the purchase price set forth in Section 1(b) hereof is determined after 4:30 p.m., New York City time, the fourth) business day after the date of this Agreement, or at such time on such other date, not later than seven business days after the date of this Agreement, as may be agreed upon by the Company and the Representatives (such date is hereinafter referred to as the “Closing Date”).

To the extent the Option is exercised, delivery of the Option Shares against payment by the Underwriters (in the manner specified above) will take place at the offices specified above for the Closing Date at the time and date (which may be the Closing Date) specified in the Option Shares Notice.

Certificates evidencing the Shares shall be in definitive form and shall be registered in such names and in such denominations as the Representatives shall request at least two business days prior to the Closing Date or the Option Closing Date, as the case may be, by written notice to the Company, and shall be delivered by or on behalf of the Company as instructed by the Representatives through the facilities of The Depository Trust Company (“DTC”). The Company agrees to make certificates representing the Shares or evidence of their issuance available for inspection at least 24 hours prior to the Closing Date or the Option Closing Date, as the case may be.

The cost of original issue tax stamps and other transfer taxes, if any, in connection with the issuance and delivery of the Company Firm Shares and Option Shares by the Company to the respective Underwriters shall be borne by the Company. The Company will pay and save each Underwriter and any subsequent holder of the Shares harmless from any and all liabilities with

respect to or resulting from any failure or delay in paying federal and state stamp and other transfer taxes, if any, which may be payable or determined to be payable in connection with the original issuance or sale to such Underwriter of the Shares.

3. Representations and Warranties of the Company. The Company represents, warrants and covenants to each Underwriter that:

A final prospectus supplement to the Base Prospectuses relating to the Shares and the offering thereof will be filed promptly by the Company with the Commission in accordance with Rule 424(b) of the Rules and Regulations (such final prospectus supplement, as so filed, the “Prospectus Supplement”). Such registration statements at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents otherwise deemed to be a part thereof or included therein by the Rules and Regulations (including Rule 430B thereof), and any registration statements relating to the offering contemplated by this Agreement and filed pursuant to Rule 462(b) of the Rules and Regulations (“Rule 462(b)”) are herein referred to collectively as the “Registration Statements.” The term “preliminary prospectuses” means any preliminary prospectus (including any preliminary prospectus supplements) relating to the Shares and the offering thereof as first filed with the Commission pursuant to Rule 424(a) or Rule 424(b) of the Rules and Regulations (“Rule 424(a)” and “Rule 424(b)”, respectively). The term “Prospectus” means the Base Prospectuses together with the Prospectus Supplement, except that if such Base Prospectuses are amended or supplemented on or prior to the date on which the Prospectus Supplement was first filed pursuant to Rule 424(a) or Rule 424(b), the term “Prospectus” shall mean the Base Prospectuses as so amended or supplemented and as supplemented by the Prospectus Supplement. Any reference herein to the Registration Statements, the Base Prospectuses, a preliminary prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statements, the Base Prospectuses, a preliminary prospectus, the Prospectus Supplement, or the Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the time the applicable Registration Statement initially became effective (as to such Registration Statement, its “Effective Date”) and the date of the related Base Prospectus, any preliminary prospectus, the Prospectus Supplement or the Prospectus, as the case may be, and deemed to be incorporated therein by reference. The term “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the Rules and Regulations (“Rule 433”), relating to the Shares in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g).

(b) No order preventing or suspending the use of any of the Base Prospectuses, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus has been issued by the Commission, and no stop order suspending the effectiveness of any of the Registration Statements (including any related registration statement filed pursuant to

Rule 462(b)) or any post-effective amendment thereto has been issued, and no proceeding for that purpose has been initiated or threatened by the Commission. On the Effective Date of each Registration Statement, on the date each Base Prospectus, any preliminary prospectus, the Prospectus Supplement, or the Prospectus is first filed with the Commission pursuant to Rule 424(b) (if required), at all times during the period through and including the Closing Date and, if later, the Option Closing Date and when any post-effective amendment to such Registration Statement becomes effective or any amendment or supplement to the Prospectus is filed with the Commission, such Registration Statement and the Prospectus (as amended or as supplemented if the Company shall have filed with the Commission any amendment or supplement thereto), including the financial statements included or incorporated by reference in the Prospectus, did and will comply in all material respects with all applicable provisions of the Act, the Exchange Act, the rules and regulations under the Exchange Act (the “Exchange Act Rules and Regulations”), and the Rules and Regulations and will contain all statements required to be stated therein in accordance with the Act, the Exchange Act, the Exchange Act Rules and Regulations, and the Rules and Regulations. As of the applicable effective date as to each part of each Registration Statement, no part of such Registration Statements, the Prospectus or any such amendment or supplement thereto did or will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. At the Effective Date of each Registration Statement, the date of its related Base Prospectus or any amendment or supplement to such Base Prospectus, including any preliminary prospectus or the Prospectus Supplement, is filed with the Commission, the date of first use of any preliminary prospectus or the Prospectus Supplement, and the Closing Date and, if later, the Option Closing Date, the Prospectus did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As of the Applicable Time, neither (x) the Issuer General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time (as defined below), the Pricing Prospectus (as defined below) and the documents listed on Schedule III hereto, all considered together (collectively, the “General Disclosure Package”), nor (y) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

For purposes of this definition, information contained in a form of prospectus that is deemed retroactively to be a part of any of the Registration Statements pursuant to Rule 430B shall be considered to be included in the Pricing Prospectus only if the actual time that form of prospectus is filed with the Commission pursuant to Rule 424(b) is prior to the Applicable Time.

“Issuer General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule III hereto.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date that the Company notified or notifies ▇▇▇▇▇▇▇ & Company, LLC as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in any of the Registration Statements or the Prospectus, including any document incorporated by reference therein that has not been superseded or modified. If there occurs an event or development as a result of which the General Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will promptly notify the Representatives so that any use of the General Disclosure Package may cease until it is amended or supplemented to correct untrue statement or omission.

The foregoing representations and warranties in this Section 3(b) do not apply to any statements or omissions made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives specifically for inclusion in any of the Registration Statements, the Prospectus Supplement, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto.

The Company and each of its Subsidiaries are corporations duly organized, validly existing and in good standing under the laws of their respective jurisdiction of incorporation. The Company and each of its Subsidiaries have full power and authority to conduct all the activities conducted by them, to own or lease all the assets owned or leased by them and to conduct their business as described in the Registration Statements, the Pricing Prospectus and the Prospectus. The Company and each of its Subsidiaries are duly licensed or qualified to do business and in good standing as foreign corporations in all jurisdictions in which the nature of the

activities conducted by them or the character of the assets owned or leased by them make such license or qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not materially and adversely affect the Company and its Subsidiaries, taken as a whole, or their respective businesses, properties, business prospects, conditions (financial or other) or results of operations, taken as a whole (such effect is referred to herein as a “Material Adverse Effect”). Each of Rainmaker Services, Inc., a Delaware corporation, Rainmaker Service Sales, Inc., a Delaware corporation, and Rainmaker Service Contract Sales, Inc., a Delaware corporation, does not have any operations and has no assets. All of the outstanding shares of capital stock of each Subsidiary have been duly authorized and validly issued and are fully paid and nonassessable, and owned by the Company free and clear of all claims, liens, charges and encumbrances; there are no securities outstanding that are convertible into or exercisable or exchangeable for capital stock of any Subsidiary. Neither the Company nor its Subsidiaries are party to any agreement or understanding, written or oral, regarding the acquisition of an interest in any corporation, firm, partnership, joint venture, association or other entity that is required to be disclosed in the Registration Statements or the Prospectus pursuant to applicable securities laws. Complete and correct copies of the certificate of incorporation and of the by-laws of the Company and each of its Subsidiaries and all amendments thereto have been delivered to the Representatives, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date or, if later, the Option Closing Date.

Except as set forth in the Pricing Prospectus and the Prospectus, the Company does not have outstanding and, at the Closing Date and, if later, the Option Closing Date, will not have outstanding, any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or any contracts or commitments to issue or sell, any shares of capital stock, or any such warrants, convertible securities or obligations. No further approval or authority of stockholders or the Board of Directors of the Company will be required for the issuance and sale of the Company Firm Shares and the Option Shares as contemplated herein. The certificates evidencing the Shares are in due and proper legal form and have been duly authorized for issuance by the Company.

(g) The financial statements and schedules included or incorporated by reference in the Registration Statements, the Pricing Prospectus or the Prospectus present fairly the financial condition of the Company and its consolidated Subsidiaries as of the respective dates thereof and the results of operations and cash flows of the Company and its consolidated Subsidiaries for the respective periods covered thereby, all in conformity with generally accepted accounting principles applied on a consistent basis throughout the entire period involved, except as set forth in the Pricing Prospectus and the Prospectus.

(j) Except as set forth in the Registration Statements, the Pricing Prospectus and the Prospectus, there are no actions, suits or proceedings pending or, to the Company’s knowledge, threatened against or affecting, the Company, any of its Subsidiaries or any of its or their officers in their capacity as such, nor any basis therefor, before or by any federal or state court, commission, regulatory body, administrative agency or other governmental body, domestic or foreign, wherein an unfavorable ruling, decision or finding would reasonably be expected to have a Material Adverse Effect.

(k) The Company and each Subsidiary have, and at the Closing Date and, if later, the Option Closing Date, will have, performed all the obligations required to be performed by them, and are not, and at the Closing Date, and, if later, the Option Closing Date, will not be, in default, under any contract to which they are a party or by which their respective properties are bound or affected, which default would reasonably be expected to have a Material Adverse Effect. To the Company’s knowledge, no other party under any contract or other instrument to which it or any of its Subsidiaries is a party is in default in any respect thereunder, which default would reasonably be expected to have a Material Adverse Effect. Neither the Company nor any of its Subsidiaries is, and at the Closing Date and, if later, the Option Closing Date, will be, in violation of any provision of its certificate or articles of organization or by-laws or other organizational documents.

The performance of this Agreement and the consummation of the transactions contemplated hereby will not result in the creation or imposition of any lien, charge or encumbrance upon any of the assets of the Company pursuant to the terms or provisions of, or result in a breach or violation of any of the material terms or provisions of, or conflict with or constitute a default under, or give any party a right to terminate any of its material obligations under, or result in the acceleration of any obligation under, the certificate or articles of incorporation or by-laws of the Company or any of its Subsidiaries, any indenture, mortgage, deed of trust, voting trust agreement, loan agreement, bond, debenture, note agreement or other evidence of indebtedness, lease, contract or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company, any of its Subsidiaries or any of their properties is bound or affected, or violate or conflict with any judgment, ruling, decree, order, statute, rule or regulation of any court or other governmental agency or body applicable to the business or properties of the Company or any of its Subsidiaries.

(n) The Company and its Subsidiaries have good and marketable title to all properties and assets described in the Pricing Prospectus and the Prospectus as owned by them, free and clear of all liens, charges, encumbrances or restrictions, except such as are described in the Pricing Prospectus and the Prospectus or are not material to the business of the Company or its Subsidiaries.

(w) Neither the Company nor any of its Subsidiaries nor, to the Company’s knowledge, any of its or their respective employees or agents at any time during the last five years has (i) made any unlawful contribution to any candidate for foreign office, or failed to disclose fully any contribution in violation of law, or (ii) made any payment to any federal or state governmental officer or official, or other person charged with similar public or quasi-public duties, other than payments required or permitted by the laws of the United States or any jurisdiction thereof.

(x) The books, records and accounts of the Company and its Subsidiaries accurately and fairly reflect, in reasonable detail, the transactions in, and dispositions of, the assets of, and the results of operations of, the Company and its Subsidiaries. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of the Company’s consolidated financial statements in accordance with generally accepted accounting principles and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Since the date of the latest audited financial statements incorporated by reference in the Pricing Prospectus and the Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(y) The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures have been designed to ensure that material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within those entities; and such disclosure controls and procedures are effective.

(z) No labor disturbance by the employees of the Company or its Subsidiaries exists or, to the knowledge of the Company, is imminent that would reasonably be expected to have a Material Adverse Effect.

(aa) Except as would not reasonably be expected to have a Material Adverse Effect, (i) each “employee benefit plan” (within the meaning of Section 3(3) of the Employee Retirement Security Act of 1974, as amended (“ERISA”)) for which the Company or any member of its “Controlled Group” (defined as any organization which is a member of a controlled group of corporations within the meaning of Section 414 of the Internal Revenue Code of 1986, as amended (the “Code”)) would have any liability (each a “Plan”) has been maintained in compliance with its terms and with the requirements of all applicable statutes, rules and regulations including ERISA and the Code; (ii) with respect to each Plan subject to Title IV of ERISA (a) no “reportable event” (within the meaning of Section 4043(c) of ERISA) has occurred or is reasonably expected to occur, (b) no “accumulated funding deficiency” (within the meaning of Section 302 of ERISA or Section 412 of the Code), whether or not waived, has occurred or is reasonably expected to occur, (c) the fair market value of the assets under each Plan exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan) and (d) neither the Company or any member of its Controlled Group has incurred, or reasonably expects to incur, any liability under Title IV of ERISA (other than contributions to the Plan or premiums to the PBGC in the ordinary course and without default) in respect of a Plan (including a “multiemployer plan,” within the meaning of Section 4001(c)(3) of ERISA); and (iii) each Plan that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(bb) Since the date of the most recent balance sheet of the Company and its consolidated Subsidiaries reviewed or audited by the Accountants and the audit committee of the board of directors of the Company, (i) the Company has not been advised of (A) any significant deficiencies in the design or operation of internal controls that could adversely affect the ability of the Company and each of its Subsidiaries to record, process, summarize and report financial data, or any material weaknesses in internal controls and (B) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of the Company and each of its Subsidiaries, and (ii) since that date, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(cc) There is and has been no failure on the part of the Company and any of the Company’s directors or officers, in their capacities as such, to comply in all material respects with the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith.

(dd) The Company and each of its Subsidiaries (i) are in compliance with all laws, regulations, ordinances, rules, orders, judgments, decrees, permits or other legal requirements of any governmental authority, including without limitation any international, national, state, provincial, regional, or local authority, relating to the protection of human health or safety, the environment, or natural resources, or to hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”) applicable to such entity, which compliance includes, without limitation, obtaining, maintaining and complying with all permits and authorizations and approvals required by Environmental Laws to conduct their respective businesses, and (ii) have not received notice of any actual or alleged violation of Environmental Laws, or of any potential liability for or other obligation concerning the presence, disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants. There are no proceedings that are pending, or known to be contemplated, against the Company or any of its Subsidiaries under Environmental Laws in which a governmental authority is also a party; the Company and its Subsidiaries are not aware of any issues regarding compliance with Environmental Laws, or liabilities or other obligations under Environmental Laws or concerning hazardous or toxic substances or wastes, pollutants or contaminants, that would reasonably be expected to have a material effect on the capital expenditures, earnings or competitive position of the Company and its Subsidiaries; and none of the Company and its Subsidiaries anticipates material capital expenditures relating to Environmental Laws.

(ee) Neither the Company nor any Subsidiary is in violation of or has received notice of any violation with respect to any federal or state law relating to discrimination in the hiring, promotion or pay of employees, nor any applicable federal or state wage and hour laws, nor any state law precluding the denial of credit due to the neighborhood in which a property is situated, the violation of any of which would reasonably be expected to have a Material Adverse Affect.

If any individual Selling Stockholder or any executor or trustee for a Selling Stockholder should die or become incapacitated, or if any Selling Stockholder that is an estate or trust should be terminated, or if any Selling Stockholder that is a partnership or corporation should be dissolved, or if any other such event should occur, before the delivery of the Selling Stockholder Firm Shares hereunder, certificates representing the Selling Stockholder Firm Shares shall be delivered by or on behalf of the Selling Stockholders in accordance with the terms and conditions of this Agreement and of the Custody Agreement, and actions taken by the Management/Director Attorneys-in-Fact or the ViewCentral Attorney-in-Fact, as applicable, pursuant to the Powers-of-Attorney shall be as valid as if such death, incapacity, termination, dissolution or other event had not occurred, regardless of whether or not the Custodian, the Management/Director Attorneys-in-Fact or the ViewCentral Attorney-in-Fact, as applicable, or any of them, shall have received notice of such death, incapacity, termination, dissolution or other event.

(f) The sale of the Selling Stockholder Firm Shares to be sold by such Selling Stockholder hereunder and the performance by such Selling Stockholder of this Agreement and the Custody Agreement and the consummation of the transactions contemplated hereby and thereby will not result in a breach or violation of any of the terms or provisions of, or constitute a default under, or give any party a right to terminate any of its obligations under, or result in the acceleration of any obligation under, any indenture, mortgage, deed of trust, voting trust agreement, loan agreement, bond, debenture, note agreement or other evidence of indebtedness, lease, contract or other agreement or instrument to which such Selling Stockholder is a party or by which such Selling Stockholder or any of its properties is bound or affected, or violate or conflict with any judgment, ruling, decree, order, statute, rule or regulation of any court or other governmental agency or body applicable to such Selling Stockholder or, if such Selling Stockholder is a corporation, partnership or other entity, the organizational documents of such Selling Stockholder.

Such Selling Stockholder has not taken and will not at any time take, directly or indirectly, any action designed, or that would reasonably be expected to reasonably be expected, to cause or result in, or that will constitute, stabilization of the price of shares of Common Stock to facilitate the sale or resale of any of the Shares.

(a) The Company will not, either prior to the Applicable Time or thereafter during such period as the Prospectus is required by law to be delivered in connection with sales of the Shares by an Underwriter or a dealer, file any amendment or supplement to any of the Registration Statements, any of the Base Prospectuses or the Prospectus, unless a copy thereof shall first have been submitted to the Representatives within a reasonable period of time prior to the filing thereof and the Representatives shall have been given a reasonable opportunity to the extent practicable to comment upon the same.

(b) The Company will notify the Representatives promptly, and will confirm such advice in writing, (i) when any amendment to any of the Registration Statements has been filed or becomes effective or any amendment or supplement to the Prospectus has been filed, (ii) of any request by the Commission for amendments or supplements to any of the Registration Statements or the Prospectus or for additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of any of the Registration Statements or preventing or suspending the use of any of the Base Prospectuses, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus or the initiation of any proceedings for that purpose or the threat thereof, (iv) of the happening of any event during the period mentioned in the third sentence of Section 5(e) that in the judgment of the Company makes any statement made in any of the Registration Statements or the Prospectus untrue or that requires the making of any changes in any of the Registration Statements or the Prospectus in order to make the statements therein, in the light of the circumstances in which they are made, not misleading, and (v) of receipt by the Company or any Representatives or attorney of the Company of any other communication from the Commission relating to the Company, any of the Registration Statements, any preliminary prospectus or the Prospectus. If at any time the Commission shall issue any order suspending the effectiveness of any of the Registration Statements or preventing or suspending the use of any of the Base Prospectuses, any preliminary prospectus, the Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, the Company will make commercially reasonable efforts to obtain the withdrawal of such order at the earliest possible moment. If the Company has omitted any information from any of the Registration Statements pursuant to Rule 430B of the Rules and Regulations, the Company will comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430B and notify the Representatives promptly of all such filings. If the Company elects to rely upon Rule 462(b) under the Act, the Company shall file a registration statement under Rule 462(b) with the Commission in compliance with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of this Agreement, and the Company shall at the time of filing either pay to the Commission the filing fee for such Rule 462(b) registration statement or give irrevocable instructions for the payment of such fee pursuant to the Rules and Regulations.

(c) The Company will furnish to each Representative, without charge, one signed copy of each of the Registration Statements and of any pre- or post-effective amendment

thereto, including financial statements and schedules, and all exhibits thereto and will furnish to the Representatives, without charge, for transmittal to each of the other Underwriters, a copy of the Registration Statements and any pre- or post-effective amendment thereto, including financial statements and schedules but without exhibits.

(d) The Company will comply with all the provisions of any undertakings contained in the Registration Statements.

(e) So long as delivery of a prospectus by an Underwriter or a dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Rules and Regulations), the Company will deliver to each of the Underwriters, without charge, as many written and electronic copies of each preliminary prospectus, the Base Prospectuses, the Prospectus Supplement, the Prospectus and each Issuer Free Writing Prospectus as the Representatives may reasonably request. The Company consents to the use of each preliminary prospectus, the Base Prospectuses, the Prospectus Supplement, the Prospectus, each Issuer Free Writing Prospectus or any amendment or supplement thereto by the Underwriters and by all dealers to which the Shares may be sold, both in connection with the offering or sale of the Shares and for any period of time thereafter during which the Prospectus is required by law to be delivered in connection therewith. If during such period of time any event shall occur that in the judgment of the Company or counsel to the Underwriters should be set forth in the Prospectus in order to make any statement therein, in the light of the circumstances under which it was made, not misleading, or if it is necessary to supplement or amend the Prospectus to comply with law, the Company will forthwith prepare and duly file with the Commission an appropriate supplement or amendment thereto, and will deliver to each of the Underwriters, without charge, such number of copies of such supplement or amendment to the Prospectus as the Representatives may reasonably request. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statements, the Pricing Prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representatives and, if requested by the Representatives, will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) Prior to any public offering of the Shares, the Company will cooperate with the Representatives and counsel to the Underwriters in connection with the registration or qualification of the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives may 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 that would subject it to general service of process in any jurisdiction where it is not now so subject.

(g) The Company will, so long as required under the Rules and Regulations, furnish to its stockholders as soon as practicable after the end of each fiscal year an annual report (including a balance sheet and statements of income, stockholders’ equity and cash flow of the Company and its consolidated Subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the effective date of the Registration Statement), consolidated summary financial information of the Company and its Subsidiaries, if any, for such quarter in reasonable detail.

(h) The Company will make generally available to holders of its securities as soon as may be practicable, but in no event later than the Availability Date (as defined below), an

earning statement (which need not be audited but shall be in reasonable detail) covering a period of 12 months commencing after the Effective Date that will satisfy the provisions of Section 11(a) of the Act (including Rule 158 of the Rules and Regulations).

The Underwriters may deem the Company to be the primary obligor with respect to all costs, fees and expenses to be paid by the Company and by the Selling Stockholders. The Selling Stockholders will pay (directly or by reimbursement) all fees and expenses incident to the performance of their obligations under this Agreement that are not otherwise specifically provided for herein, including but not limited to all expenses and taxes incident to the sale and delivery of the Shares to be sold by such Selling Stockholders to the Underwriters hereunder, and with respect to the ViewCentral Selling Stockholders, the fees, disbursements and other charges of counsel to the ViewCentral Selling Stockholders. Each Selling Stockholder will be responsible for his, her or its, as applicable, underwriting commissions and discounts applicable to such Selling Stockholder’s Firm Shares.

(j) The Company will not at any time, directly or indirectly, take any action designed or that would reasonably be expected to cause or result in, or that will constitute, stabilization of the price of the shares of Common Stock to facilitate the sale or resale of any of the Shares.

(k) The Company will apply the net proceeds from the offering and sale of the Shares to be sold by the Company in the manner set forth in the Pricing Prospectus and the Prospectus under “Use of Proceeds.”

(l) During the period beginning from the date hereof and continuing to and including the date 90 days after the date of the Prospectus, without the prior written consent of ▇▇▇▇▇▇▇ & Company, LLC, the Company will not (1) offer, sell, contract to sell, pledge, grant options, warrants or rights to purchase, or otherwise dispose of any equity securities of the Company or any other securities convertible into or exchangeable for its Common Stock or other equity security (other than pursuant to employee stock option plans disclosed in the Prospectus or pursuant to the conversion of convertible securities or the exercise of warrants in each case outstanding on the date of this Agreement) or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise; provided, however, that if (a) during the last 17 days of such 90-day period the Company issues an earnings release or material news or a material event relating to the Company occurs or (b) prior to the expiration of such 90-day period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of such 90-day period, the restrictions imposed by this Section 5(l) shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless ▇▇▇▇▇▇▇ & Company, LLC waives, in writing, such extension. Notwithstanding any of the foregoing, the foregoing shall not prohibit (x) transfer of the Shares to the Underwriters pursuant to this Agreement or (y) the issuance of, or the negotiation and execution of any agreement that contemplates the issuance of, any shares of Common Stock, or any securities exercisable or convertible into any shares of Common Stock, by the Company in connection with any acquisition or strategic transaction that the Company may enter into after the date hereof; provided that under no circumstances may such shares or other securities be sold, transferred or otherwise disposed of prior to the expiration of such 90-day period (including any extension thereof in accordance with the provisions of this Section 5(l)). For the avoidance of doubt, nothing in the foregoing paragraph shall prohibit directors and officers from executing and delivering a plan for trading shares of Common Stock in accordance with Rule 10b5-1 under the Exchange Act, provided that no sale or transfer of any shares of Common Stock under such trading plan shall be effected during the lock-up period.

(m) During the period of 90 days after the date of the Prospectus, the Company will not file with the Commission or cause to become effective any registration statement relating to any securities of the Company without the prior written consent of ▇▇▇▇▇▇▇ & Company, LLC, except for any resale registration statement relating to any shares of Common Stock, or any securities exercisable or convertible into any shares of Common Stock, issued by the Company in connection with any acquisition or strategic transaction that the Company may enter into after the date hereof.

(n) The Selling Stockholders will, and the Company will cause each of its officers and directors to, enter into lock-up agreements with the Representatives to the effect that they will not, without the prior written consent of ▇▇▇▇▇▇▇ & Company, LLC, sell, contract to sell or otherwise dispose of any shares of Common Stock or rights to acquire such shares according to the terms set forth in Schedule V hereto.

(j) At the Closing Date and, as to the Option Shares, the Option Closing Date, there shall be furnished to the Representatives a certificate, dated the date of its delivery, signed by each of the Chief Executive Officer and the Chief Financial Officer of the Company, in form and substance satisfactory to the Representatives, to the effect that:

i) Each signer of such certificate has carefully examined the Registration Statements, the Prospectus and the General Disclosure Package (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Pricing Prospectus and the Prospectus) and (A) as of the date of such certificate, such documents are true and correct in all material respects and do not omit to state a material fact required to be stated therein or necessary in order to make the statements therein not untrue or misleading and (B) in the case of the certificate delivered at the Closing Date and the Option Closing Date, since the Effective Dates no event has occurred as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein not untrue or misleading.

8. Indemnification.

(a)(1) The Company will indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who

controls each Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, liabilities, expenses and damages (including any and all 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 they, or any of them, may become subject under the Act, the Exchange 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 any untrue statement or alleged untrue statement of a material fact contained in the Registration Statements, any preliminary prospectus, the Base Prospectuses, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading in the light of the circumstances in which they were made, or arise out of or are based in whole or in part on any inaccuracy in the representations and warranties of the Company contained herein or any failure of the Company to perform its obligations hereunder or under law in connection with the transactions contemplated hereby; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by an Underwriter and 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 any Underwriter furnished in writing to the Company by the Representatives, on behalf of any Underwriter, expressly for inclusion in the Registration Statements, any preliminary prospectus, the Base Prospectuses, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. The Company acknowledges that the statements set forth in the paragraphs 1, 5, 12, 13, 14 and 15 under the heading “Underwriting” in the Pricing Prospectus and the Prospectus constitute the only information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of the Underwriters expressly for inclusion in the Registration Statements, any preliminary prospectus, the Base Prospectuses, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that the Company would reasonably be expected to otherwise have.

(2) Each of the Selling Stockholders, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who controls each Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, liabilities, expenses and damages (including any and all 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 they, or any of them, may become subject under the Act, the Exchange 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 any untrue statement or alleged untrue statement of a material fact contained in the Registration Statements, any preliminary prospectus, the Base Prospectuses, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Rules and Regulations, or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading in the light of the circumstances in which they were made, provided in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing to the Company by or on behalf of any such Selling Stockholder expressly for inclusion in the “Selling Stockholders” section therein, or arise out of or are based in whole or in part on any inaccuracy in the representations and warranties of the Selling Stockholders contained herein or any failure of the Selling Stockholders to perform its or their obligations hereunder or under law in connection with the transactions contemplated hereby; provided further that the liability of each Selling Stockholder under this Section 8(a) shall not exceed the net proceeds received by such Selling Stockholder in connection with the sale of such Selling Stockholder’s Firm Shares.

(b) Each Underwriter will indemnify and hold harmless the Company, each director of the Company, each officer of the Company who signs the Registration Statements, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and each Selling Stockholder to the same extent as the foregoing indemnity from the Company and each Selling Stockholder to each Underwriter, as set forth in Section 8(a), 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 any Underwriter furnished in writing to the Company by the Representatives, on behalf of such Underwriter, expressly for use in the Registration Statements, any preliminary prospectus, the Base Prospectuses, the Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity will be in addition to any liability that each Underwriter would otherwise have.

(c) Any party that proposes to assert the right to be indemnified under this Section 8 shall, 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 in writing of the commencement of such action, enclosing with such notice 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, such omission results in the material loss of substantive rights or defenses by the indemnifying party. If any such action is 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. 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 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 (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying 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 (iv) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party 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. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified

party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party. 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 or delayed).

(d) If the indemnification provided for in this Section 8 is applicable in accordance with its terms but for any reason is held to be unavailable to or insufficient to hold harmless an indemnified party under paragraphs (a), (b) and (c) of this Section 8 in respect of any losses, claims, liabilities, expenses and damages referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable (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 or the Selling Stockholders from persons other than the Underwriters, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statements and directors of the Company, who also may be liable for contribution) by such indemnified party as a result of such losses, claims, liabilities, expenses and damages in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand. The relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. 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 relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, with respect to the statements or omissions that 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, the Selling Stockholders or the Representatives on behalf of the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders and the Underwriters 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 (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that 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 purposes 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), no Underwriter shall be required to contribute any amount in excess of the underwriting discounts received by it and no Selling Stockholder shall be required to contribute any amount in excess of the net proceeds received by such Selling Stockholder in connection with the sale of such Selling Stockholder’s Firm Shares. No person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint. For purposes of this Section 8(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statements 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 any 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).

(e) The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company and the Selling Stockholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters, (ii) acceptance of any of the Shares and payment therefor, or (iii) any termination of this Agreement.

9. Reimbursement of Certain Expenses. In addition to its other obligations under Section 8(a) of this Agreement, the Company hereby agrees to reimburse the Underwriters on a quarterly basis for all reasonable legal and other expenses incurred in connection with investigating or defending any claim, action, investigation, inquiry or other proceeding arising out of or based upon, in whole or in part, any statement or omission or alleged statement or omission, or any inaccuracy in the representations and warranties of the Company or the Selling Stockholders contained herein or failure of the Company or the Selling Stockholders to perform its or their respective obligations hereunder or under law, all as described in Section 8(a), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligations under this Section 9 and the possibility that such payment would reasonably be expected to later be held to be improper; provided, however, that, to the extent any such payment is ultimately held to be improper, the persons receiving such payments shall promptly refund them.

10. Termination. The obligations of the several Underwriters under this Agreement may be terminated at any time on or prior to the Closing Date (or, with respect to the Option Shares, on or prior to the Option Closing Date), by notice to the Company and the Selling Stockholders from the Representatives, without liability on the part of any Underwriter to the Company or any Selling Stockholder (in accordance with Section 12) if, prior to delivery and payment for the Firm Shares or Option Shares, as the case may be, in the sole judgment of the Representatives, (i) trading in any of the equity securities of the Company shall have been suspended or limited by the Commission or by the NGM, (ii) trading in securities generally on the New York Stock Exchange or the NGM shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchanges, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange, by order of the Commission or any court or other governmental authority, or by the New York Stock Exchange or the NGM, (iii) a general banking moratorium shall have been declared by either federal, New York State or California State authorities or any material disruption of the securities settlement or clearance services in the United States shall have occurred, or (iv) any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States, any outbreak or material escalation of hostilities involving the United States, a declaration of a national emergency or war by the United States, or other calamity or crisis, either within or outside the United States, shall have occurred, the effect of which is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to proceed with completion of the public offering or the delivery of and payment for the Shares.

If this Agreement is terminated pursuant to Section 11 hereof, neither the Company nor any Selling Stockholder shall be under any liability to any Underwriter except as provided in Sections 5(j), 8 and 9 hereof; but, if for any other reason the purchase of the Shares by the Underwriters is not consummated or if for any reason the Company shall be unable to perform its obligations hereunder,

the Company will reimburse the Underwriters for reasonable all out-of-pocket expenses (including the fees, disbursements and other charges of counsel to the Underwriters) incurred by the Underwriters in connection with the offering of the Shares.

11. Substitution of Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase any of the Firm Shares that it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Firm Shares, the other Underwriters shall be obligated, severally and not jointly, to purchase the Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase, in the proportions which the number of Firm Shares that they have respectively agreed to purchase pursuant to Section 1 bears to the aggregate number of Firm Shares which all such non-defaulting Underwriters have so agreed to purchase, or in such other proportions as the Representatives may specify; provided that in no event shall the maximum number of Firm Shares that any Underwriter has become obligated to purchase pursuant to Section 1 be increased pursuant to this Section 11 by more than one-ninth of such number of Firm Shares without the prior written consent of such Underwriter. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statements and the Prospectus or in any other documents or arrangements may be effected. If any Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares that it or they agreed to purchase hereunder and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase exceeds one-tenth of the aggregate number of the Firm Shares and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders for the purchase or sale of any Shares under this Agreement. Any action taken pursuant to this Section 11 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11. No Fiduciary Relationship. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters, the Company and each Selling Stockholder acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement (including the determination of the terms of the offering of the Shares) is an arm’s-length commercial transaction between the Company and the Selling Stockholders, on the one hand, and the several Underwriters, on the other hand, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or any Selling Stockholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or any Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or any such Selling Stockholder on other matters) or any other obligation to the Company or any Selling Stockholder except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company or any such Selling Stockholder and have no obligation to disclose or account to the Company or any such Selling Stockholder for any of such differing interests, and (v) the Company and each Selling Stockholder has consulted its own legal, tax, accounting and financial advisors to the extent it deemed appropriate. The Company and each Selling Stockholder hereby agrees that it will not claim that the Underwriters, or any of them, have rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or any Selling Stockholder, in connection with such transaction or the process leading thereto.

12. Miscellaneous. 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,

The undersigned is a holder of securities of Rainmaker Systems, Inc., a Delaware corporation (the “Company”), and wishes to facilitate the public offering of shares of the Common Stock (the “Common Stock”) of the Company (the “Offering”) pursuant to an underwriting agreement (the “Underwriting Agreement”) to be entered into by and among the Company, certain stockholders of the Company and the underwriters for the Offering.

In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇▇▇▇ & Company, LLC, the undersigned will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.
