(b) On the Closing Date and the Option Closing Date, as the case may be, the Underwriters shall have received:

(i) The opinion, dated the Closing Date and the Option Closing Date, as the case may be, of Xxxxxxxxxx Xxxxxx & Xxxxxxx LLP, counsel for the Company, in the form reasonably satisfactory to counsel for the Underwriters, and their negative assurance letter, dated the Closing Date and the Option Closing Date, as the case may be, in the form reasonably satisfactory to counsel for the Underwriters.

(i) the representations, warranties and covenants of the Company contained in this Agreement are true and correct in all material respects as of the date of the Agreement (except to the extent that any of such representations and warranties are already qualified as to materiality herein, in which case, such representations and warranties shall be true and correct without further qualification), and the Closing Date and the Option Closing Date, as the case may be, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied in all material respects hereunder on or before the Closing Date and the Option Closing Date, as the case may be;

(ii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to his knowledge, threatened; and

Notice of such cancellation shall be given to the Company in writing or by telephone or telegraph confirmed in writing.

7. Indemnification and Contribution.

(a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement, the Preliminary Prospectus, the General Disclosure Package or the Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, damage or liability arises out or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by the Representatives consists of the information described as such in subsection (b) below.

(b) Each Underwriter will indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and 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, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement, the Preliminary Prospectus, the General Disclosure Package or the Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omissions or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter

through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigation or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriters consists of the following information in the Prospectus Supplement furnished on behalf of the Underwriters: the last paragraph under the caption “Underwriting.”

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above, except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. 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.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same

proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriters shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by them and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriters has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in Section 7(d).

(e) Notwithstanding any other provision of this Section 7, no party shall be entitled to indemnification and contribution under this Agreement in violation of Section 17(i) of the Investment Company Act.

8. Termination of Agreement.

(a) The obligations of the Underwriters under this Agreement may be terminated at anytime on or prior to the Closing Date, by notice given to the Company if, prior to the delivery and payment for the Shares there shall have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, net worth, or properties of the Company and its Subsidiaries taken as a whole which, in the judgment of the Underwriters, is material and adverse and makes it impractical or inadvisable to market the Shares; (ii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which is such as to make it, in the judgment of the Underwriters, impractical to market or to enforce contracts for the sale of the Shares, whether in the primary market or in respect of dealings in the secondary market; (iii) any suspension or material limitation of trading in securities generally on the NYSE, the American Stock Exchange or the Nasdaq, or any setting of minimum or maximum prices for trading on such exchange; (iv) any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by any U.S. federal or New York authorities; (vi) any major disruption of settlements of securities, payment, or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it impractical or inadvisable to market the Shares or to enforce contracts for the sale of the Shares

9. Default of Underwriters.

(a) If any Underwriter defaults in its obligations to purchase Shares hereunder on the Closing Date or the Option Closing Date and the aggregate number of Shares with respect to which such default or defaults occur exceeds 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Shares by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of the Company, except as provided in Section 10 (provided that if such default occurs with respect to Shares after the Closing Date or Option Closing Date, this Agreement will not terminate as to the Shares purchased prior to termination). As used in this Agreement, the term “Underwriters” includes any person substituted for the Underwriters under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations.

(a) The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect regardless of any investigation or statement as to the results thereof, made by or on behalf of the Underwriters, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If the purchase of the Shares by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof, Section 8(a)(ii), Section 8(a)(iii), Section 8(a)(v), Section 8(a)(vi) or Section 8(a)(vii), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Shares, and the respective obligations of the Company and the Underwriters pursuant to Section 7 hereof shall also remain in effect. In addition, if any Shares have been purchased hereunder, the representations and warranties in Section 1 and all obligations under Section 5 shall remain in effect.

Re: Hercules Technology Growth Capital, Inc. (the “Company”)

Ladies and Gentlemen:

The undersigned is an owner of record or beneficially of certain shares of common stock of the Company (the “Shares”). The Company proposes to carry out a public offering (the “Offering”) of the Shares in accordance with the Securities Act of 1933, as amended (the “Securities Act”) for which Citigroup Global Markets Inc. and Xxxxx Fargo Securities, LLC will act as representatives (in such capacity, the “Representatives”) of the several Underwriters (collectively the “Underwriters”), as set forth in the Underwriting Agreement. The undersigned recognizes that the Offering will be of benefit to the undersigned and will benefit the Company by, among other things, raising additional capital for its operations.
