Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act and the disclosure requirements of Item 405 of SEC Regulation S-K require that our directors and executive officers, and any persons holding more than 10% of any class of our equity securities report their ownership of such equity securities and any subsequent changes in that ownership to the SEC, The Nasdaq Stock Market and to us. Based solely on a review of the written statements and copies of such reports furnished to us by our executive officers, directors and greater than 10% beneficial owners, we believe that during fiscal 2006 all Section 16(a) filing requirements applicable to the executive officers, directors and stockholders were timely satisfied, except that due to an administrative error, a Form 4 report reflecting the purchase of shares by Mr. Badavas was filed one day late.

We have adopted a code of business conduct and ethics that applies to directors, officers and employees. The code of business conduct and ethics is available on our website at http//www.herculestech.com. We will report any amendments to or waivers of a required provision of the code of business conduct and ethics on our website or in a Form 8-K.

Compensation Discussion and Analysis

Compensation Philosophy

The compensation and benefit programs of Hercules Technology Growth Capital, Inc. are designed with the goal of providing compensation that is fair, reasonable and competitive. The programs are intended to help us align the compensation paid to our executive officers with corporate and executive performance goals that have been established to achieve both our short-term and long-term objectives. We also believe that the compensation programs should enable us to attract, motivate, and retain employees who will contribute to our future success.

The design of the Company’s compensation programs is based on the following:

We compete with private equity, mezzanine and hedge funds for investment professionals. Such funds commonly pay 20% of the net profits (including capital gains), or carried interest, of each newly-raised fund to the partners and employees of the private equity, mezzanine or hedge fund. Thus, we believe that our employee option plans should be designed to provide an economic interest in us similar to that generally gained by partners and employees in private equity, mezzanine lenders, venture capital or hedge funds.

The consultant recommends to the Compensation Committee changes in the mix of cash versus equity compensation to be offered as well as the types of long-term incentives to be granted. The consultant makes suggestions related to the types of performance measures to be used in the Company’s annual and long-term plans consistent with our business strategies and presents the relevant practices of peer companies. The consultant and the Company developed a list of peer companies based on market size, industries, geographic regions and other factors to be used for compensation and financial analyses. The comparative group included ten business development companies and six other specialty finance companies. However, given the fact that most of our direct competitors are private equity partnerships, specific compensation with respect to our direct competitors typically is not publicly available.

During 2006, the consultant also prepared summary analyses of total compensation for the Compensation Committee with respect to each of the named executive officers and our origination team. These summaries included all forms of current compensation including salary, annual incentives, long-term incentives, and employee benefits.

The consultant shares preliminary findings with the Chair of the Compensation Committee and presents the full report to the Compensation Committee. The Compensation Committee reviews the information provided by the consultant, including the summary analyses of key elements of compensation paid to each of the peer group executives and members of the origination team. In 2006, using the information previously provided by the consultant, the Compensation Committee determined the appropriate mix of short-term and long-term compensation for the Chief Executive Officer and, based upon recommendations from the Chief Executive Officer concerning individual performance, also determined the appropriate mix of short-term and long-term compensation for each of the other named executive officers.

Table of Contents

Components of Total Compensation

The Compensation Committee determined that the compensation packages for 2006 for its named executive officers should consist of the following three key components:

Annual Base Salary

Base salary is designed to attract and retain experienced executives who can drive the achievement of our goals and objectives. While our executive’s initial base salaries are determined by an assessment of competitive market levels for comparable experience and responsibilities, the factors used in determining changes in base salary include individual performance, changes in role and/or responsibility and changes in the competitive market environment.

Annual Cash Bonus

The annual cash bonus is designed to reward our executives that have achieved certain corporate and executive performance objectives. The amount of the annual cash bonus is determined by the Compensation Committee on a discretionary basis and is dependent on the achievement of certain quantitative and qualitative objectives during the year that were established to achieve both short-term and long-term objectives.

Table of Contents

Incentive Stock Option Awards

The Compensation Committee’s principal objective in awarding incentive stock options is to align each optionee’s interests with our success and the financial interests of its stockholders. The Compensation Committee evaluates a number of criteria, including the past service of each such optionee, the present and potential contributions of such optionee our success, years of service, position, and such other factors as the Compensation Committee believes to be relevant in connection with accomplishing the purposes of the long-term goals of the Company. The Compensation Committee does not apply a formula assigning specific weights to any of these factors when making its determination. The Compensation Committee awards incentive stock options on a subjective basis and such awards depend in each case on the performance of the executive under consideration, and in the case of new hires, their potential performance. See “2004 Stock Incentive Plan” for additional information.

Option awards under the 2004 Equity Incentive Plan are generally awarded upon initial employment and on an annual basis thereafter. Options generally vest one-third one year after the date of grant and one-third on each of the next two anniversaries.

On July 7, 2006, we applied for exemptive relief with the SEC in order to permit us to issue restricted stock pursuant to the 2004 Equity Incentive Plan and the 2006 Non-Employee Director Plan (together, the “Plans”). The SEC has commenced its review of the exemptive application and we are currently responding to questions on the relief request, but as of the date hereof, we have not received approval of the application and accordingly cannot evaluate when or if an order regarding our application may be granted.

We believe that the issuance of restricted stock permits us to provide long-term incentives to attract experienced business professionals who might otherwise elect to become employed with private equity, mezzanine lenders, venture capital firms or hedge funds.

Under the Plans, grants of restricted shares cannot exceed 10% of our issued and outstanding shares of stock at any time and grants of restricted stock and options together, cannot exceed 25 percent of the issued and outstanding shares of stock at any time. If any awards of restricted stock awards are made, such awards will reduce on a percentage basis the total number of shares of stock for which options may be awarded. All awards granted under the Plans will be in the form stock options if we do not receive exemptive relief from the SEC to issue restricted stock. No more than 1,000,000 shares of our common stock may be made subject to awards under the Stock Plan to any individual in any year.

Benefits and Perquisites

In addition to base salaries, annual cash bonuses and incentive stock option awards, we provide our executives with certain other benefits to assist in remaining competitive in the marketplace. All executive officers and other full-time employees receive general health and welfare benefits, which consist of life and health insurance benefits and the opportunity to participate in our defined contribution 401(k) plan. Our 401(k) plan does not currently provide for a match of contributions by the Company. Our executive officers receive the same benefits and perquisites as our full-time employees. Other than the benefits described above, our executive officers do not receive any other benefits or perquisites from the Company.

Tax and Accounting Implications

Stock-Based Compensation. The Company accounts for stock-based compensation, including options granted pursuant to its 2004 Equity Incentive Plan in accordance with the requirements of SFAS No. 123R.

Deductibility of Executive Compensation. Our compensation philosophy and policies are intended to comply with Code Section 162(m) and related regulations, which establish certain requirements in order for performance-based compensation in excess of $1,000,000 paid to certain executive officers to be deductible by

Table of Contents

us. In establishing and administering our compensation programs, the Compensation Committee generally intends that performance-based compensation will be deductible under Code Section 162(m), although we retain the flexibility to pay compensation that is not eligible for such treatment if it is in our best interest to do so.

The Compensation Committee is comprised entirely of independent directors who are also non-employee directors as defined in Rule 16b-3 under the Securities Exchange Act of 1934 and independent directors as defined by Nasdaq Global Market rules.

The Compensation Committee operates pursuant to a charter that sets forth the mission of the Compensation Committee and its specific goals and responsibilities. The Compensation Committee Charter is available on our website at www.herculestech.com. The Compensation Committee evaluates the compensation of the executive officers and their performance relative to their compensation to assure that they are compensated effectively in a manner consistent with the compensation philosophy discussed above. In addition, the Compensation Committee evaluates and makes recommendations to the Board regarding the compensation of the directors.

The key member of management involved in the compensation process is our Chief Executive Officer, Manuel Henriquez. Mr. Henriquez identifies certain corporate and executive performance objectives that have been established to achieve short-term and long-term objectives that are used to determine total compensation. Mr. Henriquez also recommends the overall funding level for the annual cash bonus plan. Mr. Henriquez’s recommendations are presented to the Compensation Committee for review and approval, but he is not a member of the Compensation Committee and is not involved in the deliberations of the Committee.

The Compensation Committee makes all decisions with respect to compensation of the named executive officers, subject to review and approval by the full Board of Directors. The Chief Executive Officer reviews the performance of our executive officers (other than himself) and, based on that review, provides input regarding the performance of the other executive officers and makes recommendations for compensation amounts payable to the other executive officers, including the other named executive officers. Our Compensation Committee meets outside of the presence of the Chief Executive Officer when reviewing and determining his compensation.

Company Compensation Policies

In determining the individual compensation for the Company’s executives and employees, the Compensation Committee considers the total compensation to be awarded to each executive and employee and exercises discretion in determining the portion allocated to the various components of total compensation. We believe that the focus on total compensation provides the ability to align compensation decisions with short-term and long-term needs of the business. This approach also allows for the flexibility needed to recognize differences in performance by providing differentiated compensation plans to its executives and employees.

Assessment of Company Performance

In determining the 2006 annual cash bonuses for the executives, the Compensation Committee considered the achievement of certain corporate and executive performance objectives and the short-term and long-term objectives of the company as described above. During 2006, we achieved several strategic investment and operational goals and objectives, including increasing revenues to $29.5 million representing a 177% increase over 2005 revenues of $10.7 million, generating $3.3 million in net realized gains attributed to sales of warrants and equity in four portfolio companies, raising approximately $143 million in net proceeds from the sale of our common stock, increasing our credit facility from $100 million to $150 million, investing $193 million in 35 total portfolio companies, paying $1.20 in dividends to stockholders, and expanding its organizational capabilities through growth in investment talent in our Palo Alto office and regional offices in Boulder and Boston.

Determination of 2006 Salaries of Named Executive Officers

The Compensation Committee reviews the components of the compensation provided to our executives.

Individual compensation levels for executives are determined based on individual performance and the achievement of certain corporate and executive performance objectives that have been established to achieve our short-term and long-term objectives.

Increases to base salary are awarded when necessary to address significant changes in the external competitive market for a given position, to recognize an executive for assuming significant additional responsibilities and his/her related performance, or to achieve an appropriate competitive level due to a promotion. Annual increases are generally approved by the Compensation Committee in June or July of each year.

During fiscal 2006, Messrs. Henriquez, Lund, Harvey, Bhaumik and Shah received base salaries of $550,000, $200,000, $190,000, $210,000 and $210,000, respectively, and base salaries in 2005 of $550,000, $160,000, $150,000, $175,000 and $175,000, respectively.

Determination of 2006 Annual Cash Bonus for Named Executive Officers

In determining the amount of an executive’s variable compensation—the annual cash bonus—the Compensation Committee evaluates the executive’s performance based on qualitative and quantitative measures. For example, new funding originations during the year, yields on our investment portfolio, realized and unrealized gains, credit performance of the investment portfolio, operating efficiency, information system improvements, timeliness of public reporting, amongst other things. Within those guidelines, the Committee considers the overall funding available for such awards, the executive’s performance, and the desired mix between the various components of total compensation. Discretion is exercised in determining the overall total compensation to be awarded to the executive. As a result, the amounts delivered in the form of an annual cash bonus are designed to work together in conjunction with base salary to deliver an appropriate total compensation level to the executive.

We believe that the discretionary design of our variable compensation program supports its overall compensation objectives by allowing for significant differentiation of compensation based on individual performance and by providing the flexibility necessary to ensure that compensation packages for its executives are competitive relative to its market.

During fiscal 2006, Messrs. Henriquez, Lund, Harvey, Bhaumik and Shah received cash bonuses of $1,000,000, $100,000, $100,000, $25,000 and $272,500, respectively, as compared to cash bonuses for 2005 of $700,000, $50,000, $100,000, $65,000 and $150,000, respectively.

Incentive Stock Option Awards

Our principal objective in awarding incentive stock option awards to the eligible executive officers and employees is to align each optionee’s interests with our success and the financial interests of our stockholders by linking a portion of such optionee’s compensation with the long-term performance. The Compensation Committee awards incentive stock option awards on a subjective basis and such awards depend in each case on the performance of the executive and employee under consideration, and in the case of new hires, their potential performance. Incentive stock option awards are priced at the closing price of the stock on the date the Committee meets and the grant is issued. The Compensation Committee takes into account whether there is material non-public information related to the Company at the time of the option grant, among other factors, when granting stock options. See “2004 Equity Incentive Plan” for additional information.

Potential Payments Upon Termination or Change of Control

Upon specified covered transactions (as defined in the 2004 Equity Incentive Plan), in which there is an acquiring or surviving entity, the Board may provide for the assumption of some or all outstanding awards, or for the grant of new awards in substitution, by the acquiror or survivor or an affiliate of the acquiror or survivor, in each case on such terms and subject to such conditions as the Board determines. In the absence of such an assumption or if there is no substitution, except as otherwise provided in the award, each award will become fully exercisable prior to the covered transaction on a basis that gives the holder of the award a reasonable opportunity, as determined by the Board, to participate as a stockholder in the covered transaction following exercise, and the award will terminate upon consummation of the covered transaction. A covered transaction includes the following: (i) a merger or other transaction that results in the common stock of the company being acquired by a single person or group; (ii) a sale of substantially all of the company’s assets; or (iii) a dissolution or liquidation of the company; (iv) a change in a majority of the board’s composition unless approved by a majority of the directors continuing in office.

No executive officer or employee of the Company has a written employment or severance agreement. As a result, no executive officer is entitled to any severance payments.

Compensation Committee Report

Compensation of Directors

The Compensation Committee engages an outside compensation consultant to review the competitiveness and effectiveness of our director compensation program relative to market practices within a select group of peers based on market size, industries, geographic regions and other factors. We historically have retained Watson Wyatt Worldwide, Inc. to act as its compensation consultant regarding independent director compensation. The consultant recommends to the Compensation Committee the mix of cash versus equity compensation to be offered as well as the types of long-term incentives to be granted.

Table of Contents

The following table discloses the cash, equity awards and other compensation earned, paid or awarded, as the case may be, to each of our directors during the fiscal year ended 2006.

As compensation for serving on our Board, each of our independent directors receives an annual fee of $50,000 and the chairperson of each committee receives an additional $15,000 annual fee. Each independent director also receives $2,000 for each Board or committee meeting they attend, whether in person or telephonically. Employee directors and non-independent directors will not receive compensation for serving on the Board. In addition, we reimburse our directors for their reasonable out-of-pocket expenses incurred in attending meetings of the Board.

Directors do not receive any perquisites or other personal benefits from the Company.

Under current SEC rules and regulations applicable to business development companies, a business development company may not grant options to non-employee directors, unless it receives exemptive relief from the SEC. On June 21, 2005, we applied for exemptive relief from the SEC to permit us to grant options to purchase shares of our common stock to our non-employee directors as a portion of their compensation for service on our Board and on February 15, 2007, we received approval from the SEC on this exemptive request. No stock options were granted to our non-employee directors as of December 31, 2006.

2004 Equity Incentive Plan

Our Board of Directors and our stockholders have approved the 2006 Amendment and Restatement of the Hercules Technology Growth Capital, Inc. 2004 Equity Incentive Plan, for the purpose of attracting and retaining the services of executive officers, directors and other key employees. Under the 2004 Equity Incentive Plan, our Compensation Committee may award incentive stock options within the meaning of Section 422 of the Code, or ISOs, to employees, and nonstatutory stock options to employees and directors.

Under the 2004 Equity Incentive Plan, we have authorized for issuance up to 7,000,000 shares of common stock. Participants in the 2004 Equity Incentive Plan may receive awards of options to purchase our common stock, as determined by our Compensation Committee. Options granted under the 2004 Equity Incentive Plan generally may be exercised for a period of no more than ten years from the date of grant unless the option agreement provides for an earlier expiration. Unless sooner terminated by our Board of Directors, the 2004

16

Table of Contents

Equity Incentive Plan will terminate on the tenth anniversary of its adoption and no additional awards may be made under the 2004 Equity Incentive Plan after that date. The 2004 Equity Incentive Plan provides that all awards granted under the plan are subject to modification as required to ensure that such awards do not conflict with the requirements of the 1940 Act applicable to us.

Options granted under the 2004 Equity Incentive Plan will entitle the optionee, upon exercise, to purchase shares of common stock from us at a specified exercise price per share. ISOs must have a per share exercise price of no less than the current market value of a share of stock on the date of the grant or, if the optionee owns or is treated as owning (under Section 424(d) of the Code) more than 10% of the total combined voting power of all classes of our stock, 110% of the fair market value of a share of stock on the date of the grant. Nonstatutory stock options granted under the 2004 Equity Incentive Plan must have a per share exercise price of no less than the fair market value of a share of stock on the date of the grant. Options will not be transferable other than by laws of descent and distribution, or in the case of nonstatutory stock options, by gift, and will generally be exercisable during an optionee’s lifetime only by the optionee.

Our Compensation Committee administers the 2004 Equity Incentive Plan and has the authority, subject to the provisions of the 2004 Equity Incentive Plan, to determine who will receive awards under the 2004 Equity Incentive Plan and the terms of such awards. Our Compensation Committee will have the authority to adjust the number of shares available for awards, the number of shares subject to outstanding awards and the exercise price for awards following the occurrence of events such as stock splits, dividends, distributions and recapitalizations. The exercise price of an option may be paid in the form of shares of stock that are already owned by such optionholder.

Upon specified covered transactions (as defined in the 2004 Equity Incentive Plan), all outstanding awards under the 2004 Equity Incentive Plan may either be assumed or substituted for by the surviving entity. If the surviving entity does not assume or substitute similar awards, the awards held by the participants will be accelerated in full and then terminated to the extent not exercised prior to the covered transaction.

2006 Non-Employee Director Plan

Our Board of Directors and stockholders have approved the 2006 Non-employee Director Plan (the “Director Plan”). Under current SEC rules and regulations applicable to business development companies, a business development company may not grant options to non-employee directors. On February 15, 2007, we received exemptive relief from the SEC to permit us to grant options to purchase shares of our common stock to our non-employee directors as a portion of their compensation for service on our Board. The following is a summary of the material features of the Director Plan.

The Company has instituted the Director Plan for the purpose of advancing the interests of the Company by providing for the grant of awards under the Director Plan to eligible non-employee Directors. The Director Plan authorizes the issuance of non-statutory stock options (“NSOs”) to non-employee Directors to purchase shares of common stock at a specified exercise price per share. NSOs granted under the Director Plan will have a per share exercise price of no less than the current market value of a share of stock as determined in good faith by the Board on the date of the grant.

Under the Director Plan, non-employee Directors will each receive an initial grant of an option, to purchase shares of common stock. In addition, options granted to the Company’s non-employee Directors will generally vest over two years, in equal installments on each of the first two anniversaries of the date of grant. The Compensation Committee has the authority to adjust the number of shares available for options, the number of shares subject to outstanding options under the Director Plan and the exercise price of options; provided, however, that the exercise price of options granted under the Director Plan will not be adjusted unless the Company receives an exemptive order from the SEC or written confirmation from the staff of the SEC that the Company may do so (except for adjustments resulting from changes in the Company’s capital structure, such as stock dividends, stock splits and reverse stock splits).

Table of Contents

Unless sooner terminated by the Board, the Director Plan will terminate on the tenth anniversary of its adoption and no additional awards may be made under the Director Plan after that date. The Director Plan provides that all awards granted under the Director Plan are subject to modification as required to ensure that such awards do not conflict with the requirements of the 1940 Act.

The Board will determine the period during which any options granted under the Director Plan shall remain exercisable, provided that no option will be exercisable after the expiration of ten years from the date on which it was granted. Options granted under the Director Plan are not transferable other than by will or the laws of descent and distribution, or by gift, and will generally be exercisable during a non-employee Director’s lifetime only by such non-employee Director. In general, any portion of any options that are not then exercisable will terminate upon the termination of the non-employee Director’s services to the Company. Generally, any portion of any options that are exercisable at the time of the termination of the non-employee Director’s services to the Company will remain exercisable for the lesser of (i) a period of three months (or one year if the non-employee Director’s services to the Company terminated by reason of the non-employee Director’s death) or (ii) the period ending on the latest date on which such options could have been exercised had the non-employee Director’s services to the Company not terminated. In addition, if the Board determines that a non-employee Director’s service to the Company terminated for reasons that cast such discredit on the non-employee Director as to justify immediate termination of the non-employee Director’s options, then all options then held by the non-employee Director will immediately terminate.

The Compensation Committee administers the Director Plan. Under the Director Plan, options may be granted from time-to-time for up to a maximum of 1,000,000 shares of common stock. No options have been issued pursuant to the Director Plan.

If there is a change in the capital structure of the Company by reason of a stock dividend, stock split or combination of shares (including a reverse stock split), recapitalization or other change in the Company’s capital structure, the Board will make appropriate adjustments to the number and class of shares of stock subject to the Director Plan and each option outstanding under it. In the event of a consolidation, merger, stock sale, a sale of all or substantially all of the Company’s assets, a dissolution or liquidation of the Company or other similar events (a “Covered Transaction”), the Board may provide for the assumption of some or all outstanding options or for the grant of new substitute options by the acquirer or survivor. If no such assumption or substitution occurs, all outstanding options will become exercisable prior to the Covered Transaction and will terminate upon consummation of the Covered Transaction.

On February 15, 2007, we received approval from the SEC to grant awards to our non-employee directors. We intend to award options under the Director Plan on an annual basis, though the amount of options that may be granted are limited by the terms of the Director Plan, which prohibits any grant that would cause the Company to be in violation of Section 61(a)(3) of the 1940 Act.

The Board may at any time or times amend the Director Plan or any outstanding awards for any purpose which may at the time be permitted by law, and may at any time terminate the Director Plan as to any future grants of awards; provided, that except as otherwise expressly provided in the Director Plan the Board may not, without the participant’s consent, alter the terms of an award so as to affect adversely the participant’s rights under the award, unless the Board expressly reserved the right to do so at the time of the grant of the award.

We intend to issue options and restricted shares to each of Messrs. Badavas, Chow and Woodward.

Exemptive Relief Application for Restricted Stock Awards

On July 7, 2006, we applied for exemptive relief with the SEC in order to permit us to issue restricted stock pursuant to the 2004 Equity Incentive Plan and the 2006 Non-Employee Director Plan (together, the “Plans”). The SEC has commenced its review of the exemptive application and we are currently responding to questions on the relief request, but as of the date hereof, we have not received approval of the application and accordingly cannot evaluate when or if an order regarding our application may be granted.

18

Table of Contents

We believe that the issuance of restricted stock permits us to provide long-term incentives to attract experienced business professionals who might otherwise elect to become employed with private equity, mezzanine lenders, venture capital firms or hedge funds.

Under the Plans, grants of restricted shares cannot exceed 10% of our issued and outstanding shares of stock at any time and grants of restricted stock and options together, cannot exceed 25 percent of the issued and outstanding shares of stock at any time. If any awards of restricted stock are made, such awards will reduce on a percentage basis the total number of shares of stock for which options may be awarded. All awards granted under the Plans will be in the form stock options if we do not receive exemptive relief from the SEC to issue restricted stock. No more than 1,000,000 shares of our common stock may be made subject to awards under the Stock Plan to any individual in any year.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

Equity Compensation Plan Information

The following table sets forth information as of December 31, 2006, with respect to compensation plans under which the Company’s equity securities are authorized for issuance:

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth, as of March 29, 2007, the beneficial ownership of each current director, the nominee for director, the Company’s executive officers, each person known to us to beneficially own 5% or more of the outstanding shares of our common stock, and the executive officers and directors as a group.

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission (the “SEC”) and includes voting or investment power with respect to the securities. Common stock subject to options or warrants that are currently exercisable or exercisable within 60 days of March 29, 2007 are deemed to be outstanding and beneficially owned by the person holding such options or warrants. Such shares, however, are not deemed outstanding for the purposes of computing the percentage ownership of any other person. Percentage of ownership is based on 23,090,751 shares of common stock outstanding as of March 29, 2007.

Table of Contents

Unless otherwise indicated, to our knowledge, each stockholder listed below has sole voting and investment power with respect to the shares beneficially owned by the stockholder, except to the extent authority is shared by spouses under applicable law, and maintains an address of c/o Company. Our address is 400 Hamilton Avenue, Suite 310, Palo Alto, California 94301.

Item 13. Certain Relationships and Related Transactions and Director Independence

Certain Relationships and Related Transactions

In December 2003, we entered into an engagement letter with JMP Securities LLC, the lead underwriter in our initial public offering. The engagement letter expired on June 16, 2004. Pursuant to the engagement letter, we offered to JMP Securities LLC the opportunity to act as the initial purchaser and placement agent in connection with our June 2004 private offering. As compensation for the services rendered, we agreed to pay to JMP Securities LLC an aggregate amount equal to 7% of the gross proceeds of the private offering, subject to limited exceptions in connection with sales of our securities to persons affiliated with us. In addition, we agreed to reimburse JMP Securities LLC, upon its request, for up to $150,000 of its reasonable out-of-pocket expenses. In accordance with the foregoing, we paid $1,343,619 in placement fees to JMP Securities LLC in connection with our June 2004 private placement. We have agreed to indemnify JMP Securities LLC, its affiliates and other related parties against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that such persons may be required to make for these liabilities.

In February 2004, we issued and sold 400 shares of our Series A-1 preferred stock to JMP Group LLC, the ultimate parent entity of JMP Securities LLC, for an aggregate purchase price of $2.5 million and, in connection with such sale, we paid a $175,000 placement fee to JMP Securities LLC. In addition, we issued and sold 100 shares of our Series A-2 preferred stock to an entity related to Mr. Henriquez for an aggregate purchase price of $125,000, and we issued and sold 100 shares of our Series A-2 preferred stock to Mr. Howard for an aggregate purchase price of $125,000. Our Series A-1 preferred stock held a liquidation preference over our Series A-2 preferred stock and also carried separate, preferential voting rights. In June 2004, each share of Series A-1 preferred stock and Series A-2 preferred stock was exchanged for 208.3333 units with the same terms as the units sold in our June 2004 private offering.

21

Table of Contents

In connection with the issuance of our Series A-1 preferred stock and Series A-2 preferred stock, we entered into a registration rights agreement with the holders of our Series A-1 preferred stock and Series A-2 preferred stock. In June 2004, in connection with the conversion of the Series A preferred stock, the registration rights agreement entered into in connection with the issuance of our preferred stock was terminated and the shares of our common stock issued upon conversion were included in the registration rights agreement entered into in connection with our June 2004 private offer. See “Description of Capital Stock—Registration Rights.”

We have entered into a letter agreement with Farallon Capital Management, L.L.C. that provides that prior to the date that is two years after certain investment funds controlled by Farallon Capital Management, L.L.C. cease to own at least 10% of our outstanding common stock and without the written consent of Farallon Capital Management, L.L.C., we will not (i) take any action to alter or repeal the resolution adopted by our board exempting from the Business Combination Act any business combination between us and certain investment funds managed by Farallon Capital Management, L.L.C. in a manner that would make the Business Combination Act applicable to acquisitions of our stock by such investment funds or (ii) amend the applicable provision of our bylaws in a manner that would make the Control Share Acquisition Act applicable to an acquisition of the Company’s common stock by investment funds controlled by Farallon Capital Management, L.L.C.

We have also entered into a letter agreement with JMP Asset Management LLC that provides that prior to the date that is two years after certain investment funds controlled by JMP Asset Management LLC cease to own at least 10% of our outstanding common stock and without the written consent of JMP Asset Management LLC that we will not (i) take any action to alter or repeal the resolution adopted by our board exempting from the Business Combination Act any business combination between us and certain investment funds managed by JMP Asset Management LLC in a manner that would make the Business Combination Act applicable to acquisitions of our stock by such investment funds or (ii) amend the applicable provision of our bylaws in a manner that would make the Control Share Acquisition Act applicable to an acquisition of the Company’s common stock by investment funds controlled by JMP Asset Management LLC.

In connection with our June 2004 private offering, we agreed to obtain the approval of each of JMP Asset Management LLC and Farallon Capital Management, L.L.C. for each investment made by us. Though this arrangement was terminated in connection with our election to be regulated as a business development company, under the terms of the letter agreements described above, we have agreed to indemnify, to the maximum extent permitted by Maryland law and the 1940 Act, representatives of JMP Asset Management LLC and Farallon Capital Management, L.L.C. in connection with their activities in evaluating our investment opportunities prior to our election to be regulated as a business development company on terms similar to those afforded to our directors and officers under our charter and bylaws.

In accordance with a letter agreement dated June 22, 2004 between us and JMP Group LLC, in January 2005 we issued and sold 72,000 units to funds managed by JMP Asset Management LLC at a price equal to $30.00 per unit, less a $2.10 initial purchaser’s discount per unit.

On April 12, 2005, we entered into our Bridge Loan Credit Facility with Alcmene Funding, LLC, a special purpose entity affiliated with Farallon Capital Management, L.L.C., one of our significant stockholders. In connection with the closing of the Bridge Loan Credit Facility, we paid a $500,000 upfront fee and will be obligated to pay additional fees under the terms of the facility. On August 1, 2005, we amended our Bridge Loan Credit Facility. The amendment agreement extended the term of the loan to April 12, 2006, eliminated the loan extension fee, revised the interest rate effective August 1, 2005 to LIBOR plus 5.6% through December 31, 2005 and thereafter to 13.5% per annum, and amended certain collateral rights and financial covenants. The loan fees are being amortized over the remaining ten-month period. On March 6, 2006, we entered into an amendment of our Bridge Loan Facility pursuant to which we repaid $10 million to Alcmene Funding LLC, extended the maturity date to June 30, 2006 and decreased the interest rate to 10.86%. During the year ended December 31, 2006, we fully repaid $25.0 million under our Bridge Loan Credit Facility to an affiliate of Farallon Capital Management, L.L.C. and repaid a net $10.0 million under our Citigroup Facility.

Table of Contents

At March 2, 2006, we entered into an agreement with various affiliates of Farallon Capital Management, L.L.C. to sell $5 million of common stock, priced at the net asset value on February 28, 2006. On March 20, 2006, we completed the sale of 432,900 shares of common stock to the Farallon funds at a price per share of $11.55, which was the net asset value per share at February 28, 2006.

On June 8, 2005, we entered into an Underwriting Agreement with JMP Securities LLC pursuant to which JMP Securities LLC purchased 4,200,000 shares of our common stock and served as the lead underwriter in our initial public offer.

In conjunction with the Company’s Rights offering completed on April 21, 2006, the Company agreed to pay JMP Securities LLC a fee of approximately $700,000 as co-manager of the offering.

In conjunction with the Company’s public offering completed on December 7, 2006, the Company agreed to pay JMP Securities LLC a fee of approximately $1.2 million as co-manager of the offering.

In August 2000, Mr. Henriquez acquired an interest in JMP Group LLC, the ultimate parent entity of the lead underwriter in our initial public offering. Mr. Henriquez’s interest represents approximately 0.1% of the fully-diluted equity of JMP Group LLC.

In the ordinary course of business, we enter into transactions with portfolio companies that may be considered related party transactions. In order to ensure that we do not engage in any prohibited transactions with any persons affiliated with us, we have implemented certain policies and procedures whereby our executive officers screen each of our transactions for any possible affiliations, close or remote, between the proposed portfolio investment, us, companies controlled by us and our employees and directors.

We will not enter into any agreements unless and until we are satisfied that no affiliations prohibited by the 1940 Act exist or, if such affiliations exist, we have taken appropriate actions to seek board review and approval or exemptive relief for such transaction. The board of directors reviews these procedures on an annual basis.

In addition, our code of ethics, which is signed by all employees and directors, requires that all employees and directors avoid any conflict, or the appearance of a conflict, between an individual’s personal interests and the interests of the Company. Pursuant to the code of ethics, which is available on our website at www.herculestech.com, each employee and director must disclose any conflicts of interest, or actions or relationships that might give rise to a conflict, to the Audit Committee. The Audit Committee is charged with monitoring and making recommendations to the board of directors regarding policies and practices relating to corporate governance. Certain actions or relationships that might give rise to a conflict of interest are reviewed and approved by the board of directors.

Director Independence

Our Board of Directors currently consists of four members, one who is an “interested person” of Hercules Technology Growth Capital as defined in Section 2(a)(19) of the 1940 Act and three who are not interested persons and who we refer to as our independent directors. Each member of the Audit Committee, Nominating and Corporate Governance Committee, and Compensation Committee is independent as defined by Section 2(a)(19) of the 1940 Act. See Item 10.

Audit Committee Report

The Audit Committee of the Board (the “Audit Committee”) operates under a written charter adopted by the Board effective as of February 17, 2005. The Audit Committee is currently composed of Messrs. Badavas, Chow and Woodward.

Management is responsible for the Company’s internal controls and the financial reporting process. The independent auditors are responsible for performing an independent audit of the Company’s financial statements in accordance with auditing standards generally accepted in the United States and expressing an opinion on the conformity of those audited financial statements in accordance with accounting principles generally accepted in the United States. The Audit Committee’s responsibility is to monitor and oversee these processes. The Audit Committee is also directly responsible for the appointment, compensation and oversight of the Company’s independent registered public accounting firm.

Pre-Approval Policy

The Audit Committee has established a pre-approval policy that describes the permitted audit, audit-related, tax and other services to be provided by Ernst & Young LLP, the Company’s independent registered public accounting firm. The policy requires that the Audit Committee pre-approve the audit and non-audit services performed by the independent auditor in order to assure that the provision of such service does not impair the auditor’s independence

Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval, irrespective of the amount, and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated shall report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the independent registered public accounting firm to management.

Review with Management

The Audit Committee has reviewed the audited financial statements and met and held discussions with management regarding the audited financial statements. Management has represented to the Audit Committee that the Company’s financial statements were prepared in accordance with accounting principles generally accepted in the United States.

Review and Discussion with Independent Registered Public Accounting Firm

The Audit Committee has discussed with Ernst & Young LLP, the Company’s independent registered public accounting firm, matters required to be discussed by Statement of Auditing Standards No. 61 (Communication with Audit Committees). The Audit Committee received and reviewed the written disclosures and the letter from the independent registered public accounting firm required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended by the Independence Standards Board, and has discussed with the auditors the auditors’ independence. The Audit Committee has also considered the compatibility of non-audit services with the auditors’ independence.

During 2006, the Audit Committee met with members of senior management and the independent registered public accounting firm to review the certifications provided by the Chief Executive Officer and Chief Financial Officer under the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), the rules and regulations of the SEC and the overall certification process. At these meetings, company officers reviewed each of the Sarbanes-Oxley certification requirements concerning internal control over financial reporting and any fraud, whether or not material, involving management or other employees with a significant role in internal control over financial reporting.
