Pursuant to the Credit Agreement dated as of the date hereof (as amended, supplemented or modified from time to time, the “Credit Agreement”; capitalized terms used but not defined herein shall have the meanings given such terms in the Credit Agreement) by and among Grantor, as the borrower, the Lenders party thereto and Alcmene Funding, L.L.C., as a Lender and the Administrative Agent (in such capacity, the “Administrative Agent”), Secured Party and the other Lenders, if any, have agreed to make the Loans to Grantor. In order to induce Secured Party and the other Lenders, if any, to make the Loans, Grantor has agreed to grant a continuing Lien on the Collateral to secure the Obligations (as hereinafter defined). Accordingly, Grantor hereby agrees as follows:

(a) Grant of Security. As security for the Obligations (as hereinafter defined), Grantor hereby delivers, assigns, pledges, sets over and grants to Secured Party, for the benefit of itself, the Lenders and the Administrative Agent, a first priority security interest in, subject only to Permitted Liens, all of its right, title and interest, whether now existing or hereafter arising or acquired, in and to any and all items of its personal property described on Exhibit A hereto, together with all substitutions and replacements thereof and any products and proceeds thereof including any of which are described on a supplement hereto in substantially the form of Exhibit B hereto (the “Collateral”).

(b) Security for Obligations. This Agreement secures the payment of all now existing or hereafter arising obligations of Grantor to Secured Party, the Lenders and/or the Administrative Agent, whether primary or secondary, direct or indirect, absolute or contingent, joint or several, secured or unsecured, due or not, liquidated or unliquidated, arising by operation of law or otherwise under the Credit Agreement or any other Loan Document, whether for principal, interest, fees, expenses or otherwise, together with all costs of collection or enforcement, including, without limitation, reasonable attorneys’ fees incurred in any collection efforts or in any action or proceeding (all such obligations being the “Obligations”).

(c) Grantor Remains Liable. This Agreement shall not affect Grantor’s liability to perform all of its duties and obligations under the transactions giving rise to the Obligations. The exercise by Secured Party of any of the rights hereunder shall not release Grantor from any of its duties or obligations under the transactions giving rise to the Obligations, which shall remain unchanged as if this Agreement had not been executed. Secured Party shall not have any obligation or liability under the transactions giving rise to the Obligations by reason of this Agreement, nor shall Secured Party be obligated to perform any of the obligations or duties of any Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

(d) Supplement. From time to time Grantor may deliver, assign, pledge, set over and grant to Secured Party a first priority security interest, subject only to Permitted Liens, in any additional items of personal property by delivering a supplement hereto in substantially the form of Exhibit B hereto

listing such items; thereafter, all such items of personal property shall be “Collateral” hereinafter and subject to the terms of this Agreement.

(e) Continuing Agreement. This Agreement shall create a continuing security interest in the Collateral and shall remain in full force and effect until payment in full of the Obligations.

2. Title; Liens and Encumbrances. Grantor represents and warrants that it is (or to the extent that this Agreement states that the Collateral is to be acquired after the date hereof, will be) the record and beneficial owner of, having (or to the extent that this Agreement states that the Collateral is to be acquired after the date hereof, will have) good and marketable title to, the Collateral pledged by it hereunder, free of any and all Liens or options in favor of, or claims of, any other person, except the Liens created by this Agreement and Permitted Liens. Grantor will promptly notify Secured Party of any such other Lien or claim made or asserted against the Collateral and will defend the Collateral against any such Lien or other claim.

3. State of Organization or Residence; Legal Name. Grantor represents and warrants to Secured Party as follows:

(a) Grantor is a registered Maryland corporation and is not organized under the laws of any other jurisdiction. Grantor shall promptly notify Secured Party of any change in the foregoing representation.

Grantor’s previous name was “Condor Capital Partners, Inc.” During the last five years, Grantor has used no other names, including business or trade names, other than “Hercules Technology Growth Capital, Inc.” and “Condor Capital Partners, Inc.” Grantor shall not change its name from “Hercules Technology Growth Capital, Inc.” without providing Secured Party thirty (30) days prior written notice.

(c) Grantor’s organizational identification number is D07705197. Grantor currently uses, and during the last five years has used, no other organizational identification numbers including any used by predecessors to Grantor. Grantor shall not change such organizational identification number without providing Secured Party thirty (30) days prior written notice.

(d) The grant of the security interest in the Collateral, combined with the filing of financing statements, the execution of control agreements, the execution of Assignments, and/or possession of the Collateral, each as appropriate, is effective to vest in Secured Party a valid and perfected first priority security interest, superior to the rights of any person in and to the Collateral as set forth herein, subject only to Permitted Liens.

4. Perfection of Security Interest. Grantor authorizes Secured Party to file all such financing statements and amendments thereto pursuant to the Uniform Commercial Code as in effect in the State of New York, as it may be amended, supplemented or otherwise modified from time to time (the “New York UCC”), the Uniform Commercial Code as in effect in the State of Maryland, and/or the Uniform Commercial Code of any other applicable jurisdiction, as it may be amended, supplemented or otherwise modified from time to time (the “Applicable UCC”), or other notices appropriate under applicable law, as Secured Party may require, each in form satisfactory to Secured Party. Grantor also shall pay all filing or recording costs with respect thereto, and all costs of filing or recording this Agreement or any other agreement or document executed and delivered pursuant hereto or to the Obligations (including the cost of all federal, state or local mortgage, documentary, stamp or other taxes), in each case, in all public offices where filing or recording is deemed by Secured Party to be necessary or

desirable. Grantor authorizes Secured Party to take all other action which Secured Party may deem reasonably necessary to perfect or otherwise protect the Liens created hereunder and to obtain the benefits of this Agreement.

(a) Subject to the provisions of clause (b) below, until the Obligations shall have been paid in full, and the Credit Agreement shall have terminated, Grantor covenants and agrees that if Grantor shall become entitled to receive or shall receive any certificate or instrument in respect of the Collateral (including, without limitation, share certificates, certificates representing warrants, options or other rights and promissory notes or other evidences of indebtedness issued in respect of Borrowing Loans), whether constituting, in addition to, in substitution of, as a conversion of, or in exchange for, any of the Collateral, or otherwise in respect thereof, Grantor shall accept the same as the agent of Secured Party, hold the same in trust for Secured Party and deliver the same forthwith to Secured Party in the exact form received, duly endorsed by Grantor to Secured Party, if required, together with an undated assignment covering such certificate or instrument duly executed in blank by Grantor and with, if Secured Party so requests, signature guaranteed, to be held by Secured Party, subject to the terms thereof, as additional collateral security for the Obligations. If any of the foregoing property so distributed in respect of the Collateral shall be received by Grantor, Grantor shall, until such property is paid or delivered to Secured Party, hold such property in trust for Secured Party, segregated from other funds or property of Grantor, as additional collateral security for the Obligations.

(b) For so long as the Grantor is subject to the provisions of the Investment Company Act of 1940 (the “40 Act”), Grantor shall cause Union Bank of California, N.A., or other “custodian” (as such term is used in Section 17(f) of 40 Act, hereinafter, the “Custodian”) approved in advance by the Secured Party (which approval shall not unreasonably be withheld or delayed) to hold all Collateral constituting “securities and similar investments” (as such term is used in Section 17(f) of the 40 Act, hereinafter, the “Pledged Collateral”) pursuant to a Custody Agreement executed by Grantor, the Custodian and Secured Party, substantially in the form attached hereto as Exhibit C (the “Custody Agreement”), and Grantor, in lieu of delivering such Pledged Collateral to the Secured Party as provided in subsection (a), shall deliver the same to the Custodian duly endorsed or accompanied by an assignment as aforesaid (or such endorsements or assignments may be separately delivered to Secured Party), and the Custodian shall hold the Pledged Collateral for the benefit of the Secured Party in accordance with the Applicable UCC. If the Custodian shall at any time provide notice of resignation, as provided in the Custody Agreement, the Grantor shall designate another Custodian as aforesaid prior to the effective time of such resignation, such that at all times the Pledged Collateral shall be held by a Custodian in accordance with the terms of this Agreement. Agent agrees that, other than after the occurrence and during the continuance of an Event of Default, Agent shall consent to any sale, trade, transfer, exchange or withdrawal of Pledged Collateral which is (i) required by applicable law including, but not limited to, any such transactions that are necessary to avoid a violation of the Company’s investment restrictions set forth in its Prospectus or Registration Statement on Form N-2, or (ii) necessary to maintain the Company’s status as a “regulated investment company” under Subchapter M of the Code or to avoid the imposition of any excise tax or other taxes under Subchapter M of the Code.

(c) As of the date hereof, Grantor maintains no “deposit account” (as such term is defined in the New York UCC) other than Business Checking Account number 4720029656, at Union Bank of California, N.A. (hereafter, the “Deposit Bank”). As of the date hereof, Grantor, the Deposit Bank and Secured Party shall execute a deposit account control agreement in the form of Exhibit D hereto (the “Deposit Account Control Agreement”). If, at any time, Grantor shall open any other “deposit account” (as defined in the New York UCC), Grantor agrees that it shall promptly, but in no event later than the time funds of the Grantor are first deposited in, or credited to, such deposit account, cause the

bank at which such deposit account is maintained, to execute an agreement in the form of the Deposit Account Control Agreement (or other agreement reasonably acceptable to Secured Party) in order to perfect the security interest of Secured Party in the deposit account pursuant to the Applicable UCC.

(d) As of the date hereof, Grantor maintains no “securities account” (as such term is defined in the New York UCC) Business Money Market Account number 6733000240, at Union Bank of California, N.A. (hereafter, the “Securities Intermediary”). As of the date hereof, Grantor, the Securities Intermediary and Secured Party shall execute a securities account control agreement in the form of Exhibit E hereto (the “Securities Account Control Agreement”). If, at any time, Grantor shall open any other “securities account” (as defined in the New York UCC), Grantor agrees that it shall promptly, but in no event later than the time such securities are first deposited in, or credited to, such securities account, cause the bank at which such securities account is maintained, to execute an agreement in the form of the Securities Account Control Agreement (or other agreement reasonably acceptable to Secured Party) in order to perfect the security interest of Secured Party in the securities account pursuant to the Applicable UCC.

(a) Except as provided herein or in any of the Custody Agreement, the Deposit Account Control Agreement or the Securities Account Control Agreement, Grantor may receive all cash interest, dividends and distributions paid in respect of the Collateral, and to exercise all voting rights with respect to the Collateral; provided, however, that no vote shall be cast or right exercised or other action taken which, in Secured Party’s reasonable judgment, would impair the Collateral or which would be inconsistent with or result in any violation of any provision of this Agreement or any other Loan Document.

(b) All of the foregoing amounts set forth in paragraph (a) of this Section 6 so collected after the occurrence of and during the continuation of an Event of Default shall be held in trust by Grantor for and as the property of Secured Party and, upon written notice thereof to the Grantor, shall not be commingled with other funds, money or property of Grantor.

(c) After the occurrence and during the continuation of an Event of Default, if so requested by Secured Party, Grantor will immediately upon receipt of all such checks, cash or other remittances constituting part of the Collateral or in payment for any Collateral sold, transferred, leased or otherwise disposed of, deliver any such items to Secured Party accompanied by a remittance report in form supplied or approved by Secured Party. Grantor shall deliver such items in the same form received, endorsed or otherwise assigned by Grantor where necessary to permit collection of such items.

7. Events of Default. The occurrence of any one or more Events of Default by any Obligor under the Credit Agreement shall constitute an event of default (“Event of Default”) under this Agreement.

(a) Upon the occurrence and during the continuation of any Event of Default: (i) Secured Party may exercise exclusive control over the Collateral; (ii) Secured Party shall have the right, with or without (to the extent permitted by applicable law) notice to Grantor, as to any or all of the Collateral, by any available judicial procedure or without judicial process, to take possession of the Collateral and without liability for trespass to enter any premises where the Collateral may be located for the purpose of taking possession of or removing the Collateral, and generally to exercise any and all rights afforded to a secured party under the Applicable UCC or other applicable law; (iii) Secured Party shall

have the right to sell, lease, or otherwise dispose of all or any part of the Collateral, whether in its then condition or after further preparation or processing, either at public or private sale or at any broker’s board, in lots or in bulk, for cash or for credit, with or without warranties or representations, and upon such terms and conditions, all as Secured Party in its sole discretion and in compliance with applicable law, may deem advisable; (iv) at Secured Party’s written request, Grantor shall assemble the Collateral and make it available to Secured Party at places which Secured Party shall select, whether at Grantor’s premises or elsewhere, and make available to Secured Party, without rent, all of Grantor’s premises and facilities for the purpose of Secured Party’s taking possession of, removing or putting the Collateral in saleable or disposable form; (v) Secured Party shall have the right to receive any and all cash interest, dividends, distributions, payments or other proceeds paid in respect of the Collateral and made application thereof to the Obligations in such order as Secured Party may determine; and (vi) any or all of the Collateral may be registered in the name of Secured Party or its nominee and it may thereafter exercise (x) all voting, corporate and other rights pertaining to such Collateral and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Collateral as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all securities or securities entitlements upon any merger, consolidation, reorganization, recapitalization or other fundamental change, or upon the exercise of Grantor or Secured Party of any right, privilege or option pertaining to such securities or securities entitlements, and in connection therewith, the right to deposit and deliver any and all of the securities or securities entitlements with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as Secured Party may determine), all without liability except to account for property actually received by it, but Secured Party shall have no duty to Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(b) Any such sale, lease or other disposition of Collateral may be made without demand for performance or any notice of advertisement whatsoever, except as otherwise required by law and, except that where an applicable statute requires reasonable notice of sale or other disposition, Grantor agrees that the sending of ten (10) days notice by ordinary mail, postage prepaid, to Grantor of the place and time of any public sale or of the time at which any private sale or other intended disposition is to be made, shall be deemed reasonable notice thereof. Notwithstanding the foregoing, if any of the Collateral may be materially diminished in value during such ten (10) day period, Secured Party shall provide Grantor with such shorter notice as it deems reasonable under the circumstances, except as otherwise required by law.

(c) The proceeds of any such sale, lease or other disposition of the Collateral shall be applied first to the expenses of retaking, holding, storing, processing and preparing for sale, selling, and the like, and to the reasonable attorneys’ fees and legal expenses incurred by Secured Party, and then to satisfaction of the Obligations (in any order as Secured Party may decide in its sole discretion), and to the payment of any other amounts required by applicable law. If, upon the sale, lease or other disposition of the Collateral, the proceeds thereof are insufficient to pay all amounts to which a Lender, the Administrative Agent or Secured Party is legally entitled, Grantor will be liable for the deficiency, together with interest thereon, at the rate prescribed in the agreements giving rise to the Obligations, and the reasonable fees of any attorneys employed by Secured Party to collect such deficiency. To the extent permitted by applicable law, Grantor waives all claims, damages and demands against Secured Party arising out of the repossession, removal, retention or sale of the Collateral.

9. Power of Attorney. Grantor authorizes Secured Party and does hereby make, constitute and appoint Secured Party, and any officer or agent of Secured Party, with full power of substitution, as Grantor’s true and lawful attorney-in-fact, with power, in its own name or in the name of Grantor, which power shall be effective upon the occurrence and during the continuation of an Event of Default: (i) to endorse any notes, checks, drafts, money orders, or other instruments of payment

(including payments payable under or in respect of any policy of insurance) in respect of the Collateral that may come into possession of Secured Party; (ii) to pay or discharge any taxes, liens, security interest or other encumbrances at any time levied or placed on or threatened against the Collateral; (iii) to demand, collect, receipt for, compromise, settle and sue for monies due in respect of the Collateral; (iv) to receive, open and dispose of all mail addressed to Grantor and to notify the post office authorities to change the address for delivery of mail addressed to Grantor to such address as Secured Party may designate; (v) to exercise all membership rights, powers and privileges in connection with the Collateral to the same extent as Grantor is entitled to exercise such rights, powers and privileges; and (vi) generally to do all acts and things which Secured Party deems reasonably necessary to protect, preserve and realize upon the Collateral and Secured Party’s security interest therein. Grantor hereby approves and ratifies all acts of said attorney or designee, who shall not be liable for any acts of commission or omission, nor for any error or judgment or mistake of fact or law except for its own gross negligence or willful misconduct. This power of attorney shall be irrevocable for the term of this Agreement and thereafter as long as any of the Obligations shall be outstanding.

10. Notices. Notices shall be given in the manner, to the addresses and with the effect provided in Section 10.02 of the Credit Agreement.

11. Other Security. To the extent that the Obligations are now or hereafter secured by property other than the Collateral or by the guarantee, endorsement or property of any other Person, then Secured Party shall have the right in its sole discretion to pursue, relinquish, subordinate, modify or take any other action with respect thereto, without in any way modifying or affecting any of Secured Party’s rights and remedies hereunder.

(a) No course of dealing between Grantor and Secured Party, any Lender and the Administrative Agent, or Secured Party’s failure to exercise or delay in exercising any right, power or privilege hereunder, shall operate as a waiver thereof. Any single or partial exercise of any right, power or privilege hereunder shall not preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(b) All of Secured Party’s rights and remedies with respect to the Collateral, whether established hereby or by any other agreements, instruments or documents or by law, shall be cumulative and may be exercised singly or concurrently.

14. Amendments, Etc. No amendment or waiver of any provision of this Agreement nor consent to any departure by Secured Party therefrom shall in any event be effective unless the same shall be in writing, approved by Secured Party and signed by Secured Party, and then any such waiver or consent shall only be effective in the specific instance and for the specific purpose for which given.

15. Successors and Assigns. This Agreement and all obligations of Grantor and Secured Party hereunder shall be binding upon the successors and assigns of Grantor and Secured Party, as applicable, and shall, together with the rights and remedies of Secured Party hereunder, inure to the

benefit of Secured Party, the Lenders or the Administrative Agent and their respective successors and assigns.

16. No Partnership. The relationship between Secured Party and Grantor shall be only of creditor-debtor and no relationship of agency, partner or joint- or co-venturer shall be created by or inferred from this Agreement or the other Loan Documents. Grantor shall indemnify, defend, and save Secured Party harmless from any and all claims asserted against Secured Party as being the agent, partner, or joint-venturer of Grantor.

17. Entire Agreement. This Agreement, together with the Custody Agreement, the Deposit Account Control Agreement and the Securities Account Control Agreement, embodies the entire agreement and understanding between Grantor and Secured Party with respect to its subject matter and supersedes all prior conflicting or inconsistent agreements, consents and understandings relating to such subject matter. Grantor acknowledges and agrees that there is no oral agreement between Grantor and Secured Party which has not been incorporated in this Agreement.
