PART I

Item 1. Business

GENERAL

We are a specialty finance company that provides debt and equity growth capital to technology-related and life-sciences companies at all stages of development. Our investment objective is to maximize our portfolio’s total return by generating current income from our debt investments and capital appreciation from our equity-related investments. We are an internally-managed, non-diversified closed-end investment company that has elected to be treated as a business development company under the Investment Company Act of 1940.

We primarily finance privately-held companies backed by leading venture capital and private equity firms and also may finance certain select publicly-traded companies that lack access to public capital or are sensitive to equity ownership dilution. Our principal executive office is located in the Silicon Valley and we have additional offices in the Boston, Boulder, Chicago and Columbus areas. Our goal is to be the leading structured mezzanine capital provider of choice for venture capital and private equity-backed technology-related and life sciences companies requiring sophisticated and customized financing solutions. Our strategy is to evaluate and invest in a broad range of ventures active in the technology and life science industries and to offer a full suite of growth capital products to complement a portfolio company’s existing capital structure. We invest primarily in structured mezzanine debt and, to a lesser extent, in senior debt and equity. We use the term “structured mezzanine debt investment” to refer to any debt investment, such as a senior or subordinated secured loan, that is coupled with an equity component, including warrants, options or rights to purchase common or preferred stock. Our structured mezzanine debt investments will typically be secured by some or all of the assets of the portfolio company.

We focus our investments in companies active in the technology industry sub-sectors characterized by products or services that require advanced technologies, including computer software and hardware, networking systems, semiconductors, semiconductor capital equipment, information technology infrastructure or services, Internet consumer and business services, telecommunications, telecommunications equipment, renewable or alternative energy, media and life sciences. Within the life sciences sub-sector, we focus on medical devices, bio-pharmaceutical, health care services and information systems companies. We refer to all of these companies as “technology-related” companies and intend, under normal circumstances, to invest at least 80% of the value of our assets in such businesses.

Our primary business objectives are to increase our net income, net operating income and net asset value by investing in structured mezzanine debt and equity of venture capital and private equity backed technology-related companies with attractive current yields and the potential for equity appreciation and realized gains. Our structured debt investments typically include warrants or other equity interests, giving us the potential to realize equity-like returns on a portion of our investment. In some cases, we receive the right to make additional equity investments in our portfolio companies in connection with future equity financing rounds. Capital that we provide directly to venture capital and private equity backed technology-related companies is generally used for growth and in select cases for acquisitions or recapitalizations.

Our portfolio is comprised of, and we anticipate that our portfolio will continue to be comprised of, investments in technology-related companies at various stages of their development. Consistent with regulatory

1

Table of Contents

requirements, we invest primarily in United States based companies and to a lesser extent in foreign companies. To date, our emphasis has been primarily on private companies following or in connection with their first institutional round of equity financing, which we refer to as emerging-growth companies, and private companies in later rounds of financing, which we refer to as expansion-stage companies. In 2007, we expect to increase our investment activity in established companies, comprised of private companies in one of their final rounds of equity financing prior to a liquidity event or select publicly-traded companies that lack access to public capital or are sensitive to equity ownership dilution.

We commenced investment operations in September 2004 and have built our investment portfolio on disciplined underwriting, as well as on-going portfolio management. At December 31, 2006, we had outstanding structured mezzanine debt investments representing approximately $266.7 million, warrant investments of $8.4 million and equity investments of $8.1 million for a total investment portfolio at fair value of $283.2 million. In addition, at December 31, 2006, we had unfunded contractual commitments of $55.5 million.

At December 31, 2006, the weighted average yield to maturity of our loan obligations was approximately 12.64%. Yields to maturity are computed using interest rates at inception of the loan and include amortization of loan facility fees, commitment fees and market premiums or discounts over the expected life of the debt investments, weighted by their respective costs when averaged and are based on the assumption that all contractual loan commitments have been fully funded.

CORPORATE HISTORY AND OFFICES

We are a Maryland corporation formed in December 2003 that began investment operations in September 2004. We are an internally managed, non-diversified, closed-end investment company that has elected to be treated as a business development company under the 1940 Act. As a business development company, we are required to meet various regulatory tests. A business development company is required to invest at least 70% of its total assets in private or thinly traded public U.S.-based companies. A business development company also must meet a coverage ratio of total net assets to total senior securities, which include all of our borrowings (including accrued interest payable) and any preferred stock we may issue in the future, of at least 200%.

From incorporation through December 31, 2005, we were taxed as a corporation under Subchapter C of the Internal Revenue Code. We will elect to be treated for federal income tax purposes as a RIC under the Internal Revenue Code with the filing of our federal corporate income tax return for 2006, which election, when actually made, will be effective as of January 1, 2006. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset diversification requirements. Pursuant to these elections, we generally will not have to pay corporate-level taxes on any income that we distribute to our stockholders. To obtain and maintain the federal income tax benefits of RIC status, we must meet specified source-of-income and asset diversification requirements and distribute annually an amount equal to at least 90% of the sum of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of assets legally available for distribution.

Our principal executive offices are located at 400 Hamilton Avenue, Suite 310, Palo Alto, California 94301 and our telephone number is (650) 289-3060. We also have additional offices in the Boston, Boulder, Chicago and Columbus areas. We maintain a website on the Internet at www.herculestech.com. Information contained in our website is not incorporated by reference into this Annual Report, and you should not consider that information as part of this Annual Report. Our annual reports on Form 10-K, quarterly reports on Form 10-Q and our current reports on Form 8-K, as well as any amendments to those reports, are available free of charge through our website as soon as reasonably practicable after we file them with, or furnish them to, the Securities and Exchange Commission.

Our Market Opportunity

We believe that technology-related companies compete in one of the largest and most rapidly growing sectors of the U.S. economy and that continued growth is supported by ongoing innovation and performance improvements in technology products as well as the adoption of technology across virtually all industries in response to competitive pressures. We believe that an attractive market opportunity exists for a specialty finance company focused primarily on structured mezzanine investments in technology-related companies for the following reasons:

Technology-Related Companies Underserved by Traditional Lenders. We believe many viable technology-related companies backed by financial sponsors have been unable to obtain sufficient growth financing from traditional lenders, including financial services companies such as commercial banks and finance companies, in part because traditional lenders have continued to consolidate and have adopted a more risk-averse approach to lending that has resulted in tightened credit standards in recent years. More importantly, we believe traditional lenders are typically unable to underwrite the risk associated with financial sponsor-backed emerging-growth or expansion-stage companies effectively.

The unique cash flow characteristics of many technology-related companies include significant research and development expenditures and high projected revenue growth thus often making such companies difficult to evaluate from a credit perspective. In addition, the balance sheets of emerging-growth and expansion-stage companies often include a disproportionately large amount of intellectual property assets, which can be difficult to value. Finally, the speed of innovation in technology and rapid shifts in consumer demand and market share add to the difficulty in evaluating technology-related companies.

Due to the difficulties described above, we believe traditional lenders are generally refraining from entering the structured mezzanine debt marketplace for emerging-growth and expansion-stage companies, instead preferring the risk-reward profile of senior debt. Traditional lenders generally do not have flexible product offerings that meet the needs of technology-related companies. The financing products offered by traditional lenders typically impose on borrowers many restrictive covenants and conditions, including limiting cash outflows and requiring a significant depository relationship to facilitate rapid liquidation.

Unfulfilled Demand for Structured Debt Financing to Technology-Related Companies. Private debt capital in the form of structured debt financing from specialty finance companies continues to be an important source of funding for technology-related companies. We believe that the level of demand for structured debt financing to emerging-growth and expansion-stage companies is a function of the level of annual venture equity investment activity. In 2006, venture capital-backed companies received, in approximately 2,454 transactions, equity financing in an aggregate amount of approximately $25.8 billion, representing an 8% increase over the preceding year, as reported by Dow Jones VentureOne. In addition, overall, the median round size in 2006 was $7 million, up from $6.5 million in 2005, and the highest annual median since 2000. For the second year in a row, equity investors are focusing more than a third of their investment activity on early-stage financings. Overall, seed- and first-round deals made up 36% of the deal flow in 2006, and about the same concentration of deal flow went to later-stage deals. As a result, we believe a range of $20 billion to $25 billion in annual equity investments to venture-backed companies will be sustainable for future years.

Table of Contents

We believe that demand for structured debt financing is currently unfulfilled, in part because historically the largest debt capital providers to technology-related companies exited the market during 2001 while at the same time lending requirements of traditional lenders have become more stringent. We therefore believe this is an opportune time to be active in the structured lending market for technology-related companies.

Structured Mezzanine Debt Products Complement Equity Financing From Venture Capital and Private Equity Funds. We believe that technology-related companies and their financial sponsors will continue to view structured debt securities as an attractive source of capital because it augments the capital provided by venture capital and private equity funds. We believe that our structured mezzanine debt products provide access to growth capital that otherwise may only be available through incremental investments by existing equity investors. As such, we provide portfolio companies and their financial sponsors with an opportunity to diversify their capital sources. Generally, we believe emerging-growth and expansion-stage companies target a portion of their capital to be debt in an attempt to achieve a higher valuation through internal growth. In addition, because financial sponsor-backed companies have recently been more mature prior to reaching a liquidity event, we believe our investments could provide the debt capital needed to grow or recapitalize during the extended period prior to liquidity events.

Lower Valuations for Private Technology-Related Companies. During the downturn in technology industries that began in 2000, the markets saw sharp and broad declines in valuations of venture capital and private equity-backed technology-related companies. According to Dow Jones VentureOne, median pre-money valuations for venture capital-backed companies in 2000 was $25.0 million declining to a low of $10.0 million in 2003. As of December 31, 2006 median pre-money valuations for venture capital-backed companies in 2006 was $18.5 million compared to $15.0 million in 2005. While pre-money valuations have been steadily increasing since 2003, we believe the valuations currently assigned to venture capital and private equity-backed technology-related companies in private financing rounds are still low and should allow us to continue to build a portfolio of equity-related securities at attractive valuation levels.

Our Business Strategy

Our strategy to achieve our investment objective includes the following key elements:

Leverage the Experience and Industry Relationships of Our Management Team and Investment Professionals. We have assembled a team of experienced investment professionals with extensive experience as venture capitalists, commercial lenders, and originators of structured debt and equity investments in technology-related companies. Our investment professionals have, on average, more than 15 years of experience as equity investors in, and/or lenders to, technology-related companies. In addition, our team members have originated structured mezzanine investments in over 200 technology-related companies, representing over $1.0 billion in investments, and have developed a network of industry contacts with investors and other participants within the venture capital and private equity communities. In addition, members of our management team also have operational, research and development and finance experience with technology-related companies. We have established contacts with leading venture capital and private equity fund sponsors, public and private companies, research institutions and other industry participants, which should enable us to identify and attract well-positioned prospective portfolio companies.

We concentrate our investing activities in industries in which our investment professionals have investment experience. We believe that our focus on financing technology-related companies will enable us to leverage our expertise in structuring prospective investments, to assess the value of both tangible and intangible assets, to evaluate the business prospects and operating characteristics of technology-related companies and to identify and originate potentially attractive investments with these types of companies.

Mitigate Risk of Principal Loss and Build a Portfolio of Equity-Related Securities. We expect that our investments have the potential to produce attractive risk adjusted returns through current income, in the form of

4

Table of Contents

interest and fee income, as well as capital appreciation from equity-related securities. We believe that we can mitigate the risk of loss on our debt investments through the combination of loan principal amortization, cash interest payments, relatively short maturities, security interests in the assets of our portfolio companies, covenants requiring prospective portfolio companies to have certain amounts of available cash at the time of our investment and the continued support from a venture capital or private equity firm at the time we make our investment.

In addition, historically our structured debt investments typically include warrants or other equity interests, giving us the potential to realize equity-like returns on a portion of our investment. In addition, we expect, in some cases, to receive the right to make additional equity investments in our portfolio companies in connection with future equity financing rounds. We believe these equity interests will create the potential for meaningful long-term capital gains in connection with the future liquidity events of these technology-related companies.

Provide Customized Financing Complementary to Financial Sponsors’ Capital. We offer a broad range of investment structures and possess expertise and experience to effectively structure and price investments in technology-related companies. Unlike many of our competitors that only invest in companies that fit a specific set of investment parameters, we have the flexibility to structure our investments to suit the particular needs of our portfolio companies. We offer customized financing solutions ranging from senior debt to equity capital, with a focus on structured mezzanine debt.

We use our relationships in the financial sponsor community to originate investment opportunities. Because venture capital and private equity funds typically invest solely in the equity securities of their portfolio companies, we believe that our debt investments will be viewed as an attractive source of capital, both by the portfolio company and by the portfolio company’s financial sponsor. In addition, we believe that many venture capital and private equity fund sponsors encourage their portfolio companies to use debt financing for a portion of their capital needs as a means of potentially enhancing equity returns, minimizing equity dilution and increasing valuations prior to a subsequent equity financing round or a liquidity event.

Invest at Various Stages of Development. We provide growth capital to technology-related companies at all stages of development, from emerging-growth companies, to expansion-stage companies and established companies. We believe that this provides us with a broader range of potential investment opportunities than those available to many of our competitors, who generally focus their investments on a particular stage in a company’s development. Because of the flexible structure of our investments and the extensive experience of our investment professionals, we believe we are well positioned to take advantage of these investment opportunities at all stages of prospective portfolio companies’ development.

Benefit from Our Efficient Organizational Structure. We believe that the perpetual nature of our corporate structure enables us to be a long-term partner for our portfolio companies in contrast to traditional mezzanine and investment funds, which typically have a limited life. In addition, because of our access to the equity markets, we believe that we may benefit from a lower cost of capital than that available to private investment funds. We are not subject to requirements to return invested capital to investors nor do we have a finite investment horizon. Capital providers that are subject to such limitations are often required to seek a liquidity event more quickly than they otherwise might, which can result in a lower overall return on an investment.

Deal Sourcing Through Our Proprietary Database. We have developed a proprietary and comprehensive structured query language-based (SQL) database system to track various aspects of our investment process including sourcing, originations, transaction monitoring and post-investment performance. As of December 31, 2006, our proprietary SQL-based database system included over 10,900 technology-related companies and over 3,000 venture capital private equity sponsors/investors, as well as various other industry contacts. This proprietary SQL system allows us to maintain, cultivate and grow our industry relationships while providing us with comprehensive details on companies in the technology-related industries and their financial sponsors.

Our Investments and Operations

We invest in debt securities and, to a lesser extent, equity securities, with a particular emphasis on structured mezzanine debt.

We generally seek to invest in companies that have been operating for at least six to 12 months prior to the date of our investment. We expect that such entities will, at the time of investment, be generating revenues or will have a business plan that anticipates generation of revenues within 24 to 36 months. Further, we anticipate that on the date of our investment we will obtain a lien on available assets, which may or may not include intellectual property, and these companies will have sufficient cash on their balance sheet to amortize their debt for at least six to 15 months following our investment. We generally require that a prospective portfolio company, in addition to having sufficient capital to support leverage, demonstrate an operating plan capable of generating cash flows or raising the additional capital necessary to cover its operating expenses and service its debt.

We expect that our investments will generally range from $1.0 million to $25.0 million. Our debt investments generally have an average initial principal balance of between $3.0 million and $7.0 million and have maturities of two to seven years, with an expected average term of three years. We typically structure our debt securities to provide for amortization of principal over the life of the loan, but may include an interest-only period, and our loans will be collateralized by a security interest in the borrower’s assets, although we may not have the first claim on these assets and the assets may not include intellectual property. Our debt investments carry fixed or variable contractual interest rates typically ranging from 8% to 14%. In addition to the cash yields received on our loans, in some instances, certain loans may also include any of the following: end of term payments, exit fees, balloon payment fees or prepayment fees, which we may be required to include in income prior to receipt. We also generate revenue in the form of commitment and facility fees, and to a lesser extent, due diligence fees.

In addition, historically our structured mezzanine debt investments generally have equity enhancement features, typically in the form of warrants or other equity-related securities designed to provide us with an opportunity for capital appreciation. The warrants typically will be immediately exercisable upon issuance and generally will remain exercisable for the lesser of seven years or three years after an initial public offering. The exercise prices for the warrants varies from nominal exercise prices to exercise prices that are at or above the current fair market value of the equity for which we receive warrants. We may structure warrants to provide minority rights provisions and put rights upon the occurrence of certain events. We generally target a total annualized return (including interest, fees and value of warrants) of 12% to 25% for our debt investments.

Typically, our debt and equity investments take one of the following forms:

A comparison of the typical features of our various investment alternatives is set forth in the chart below.

Investment Criteria

We have identified several criteria that we believe are important in achieving our investment objective with respect to prospective portfolio companies. These criteria, while not inclusive, provide general guidelines for our investment decisions.

Portfolio Composition. While we generally focus our investments in venture capital and private equity backed technology-related companies, we seek to diversify across various financial sponsors as well as across various stages of companies’ development and various technology industry sub-sectors and geographies.

Continuing Support from One or More Financial Sponsors. We generally invest in companies in which one or more established financial sponsors have previously invested and continue to make a contribution to the management of the business. We believe that having established financial sponsors with meaningful commitments to the business is a key characteristic of a prospective portfolio company. In addition, we look for representatives of one or more financial sponsors to maintain seats on the Board of Directors of a prospective portfolio company as an indication of such commitment.

Company Stage of Development. While we invest in companies at various stages of development, we generally require that prospective portfolio companies be beyond the seed stage of development and generally have received or have commitments for their first institutional round of equity financing. We expect a prospective portfolio company to demonstrate its ability to commence revenue generation or increase its revenues and operating cash flow over time. The anticipated growth rate of a prospective portfolio company is a key factor in determining the value that we ascribe to any warrants or other equity securities that we may acquire in connection with an investment in debt securities.

Table of Contents

Operating Plan. We generally require that a prospective portfolio company, in addition to having sufficient access to capital to support leverage, demonstrate an operating plan capable of generating cash flows or the ability to raise the additional capital necessary to cover its operating expenses and service its debt. Specifically, we require that a prospective portfolio company demonstrate at the time of our proposed investment that it has cash on its balance sheet, or is in the process of completing a financing so that it will have cash on its balance sheet, sufficient to support its operations for a minimum of 6 to 15 months.

Security Interest. In many instances we generally seek a first priority security interest in all of the portfolio company’s tangible and intangible assets as collateral for our debt investment, subject in some cases to permitted exceptions. In other cases we may prohibit a company from pledging or otherwise encumbering their intellectual property. Although we do not intend to operate as an asset-based lender, the estimated liquidation value of the assets, if any, collateralizing the debt securities that we hold is an important factor in our credit analysis. We evaluate both tangible assets, such as accounts receivable, inventory and equipment, and intangible assets, such as intellectual property, customer lists, networks and databases.

Covenants. Our investments typically include one or more of the following covenants; cross-default and material adverse change provisions, require the portfolio company to provide periodic financial reports and operating metrics and will typically limit the portfolio company’s ability to incur additional debt, sell assets, engage in transactions with affiliates and consummate an extraordinary transaction, such as a merger or recapitalization without our consent. In addition, we may require other performance or financial based covenants, as we deem appropriate.

Exit Strategy. Prior to making a debt investment that is accompanied by an equity-related security in a prospective portfolio company, we analyze the potential for that company to increase the liquidity of its equity through a future event that would enable us to realize appreciation in the value of our equity interest. Liquidity events may include an initial public offering, a private sale of our equity interest to a third party, a merger or an acquisition of the company or a purchase of our equity position by the company or one of its stockholders.

Investment Process

We have organized our management team around the four key elements of our investment process:

9

Table of Contents

Our investment process is summarized in the following chart:

Origination

The origination process for our investments includes sourcing, screening, preliminary due diligence and deal structuring and negotiation, all leading to an executed non-binding term sheet. Our investment origination team, which consists of 15 senior investment professionals is headed by our Chief Executive Officer, Mr. Henriquez, and is responsible for sourcing potential investment opportunities. The origination team uses their extensive relationships with various leading financial sponsors, management contacts within technology-related companies, trade sources, technology conferences and various publications to source prospective portfolio companies.

In addition, we have developed a proprietary and comprehensive SQL-based database system to track various aspects of our investment process including sourcing, originations, transaction monitoring and post-investment performance. As of December 31, 2006, our proprietary SQL-based database system included over 10,900 technology-related companies and over 3,000 venture capital private equity sponsors/investors, as well as various other industry contacts. This proprietary SQL system allows our origination team to maintain, cultivate and grow our industry relationships while providing our origination team with comprehensive details on companies in the technology-related industries and their financial sponsors.

If a prospective portfolio company generally meets certain underwriting criteria, we perform preliminary due diligence, which may include high level company and technology assessments, evaluation of its financial sponsors’ support, market analysis, competitive analysis, evaluation of select management, risk analysis and transaction size, pricing, return analysis and structure analysis. If the preliminary due diligence is satisfactory, and the origination team recommends moving forward, we then structure, negotiate and execute a non-binding term sheet with the potential portfolio company. Upon execution of a term sheet, the investment opportunity moves to the underwriting process to complete formal due diligence review and approval.

Table of Contents

Underwriting

The underwriting review includes formal due diligence and approval of the proposed investment in the portfolio company.

Due Diligence. Our due diligence on a prospective investment is typically completed by two or more investment professionals which we define as the underwriting team. The underwriting team for a proposed investment consists of the deal sponsor who possesses specific industry knowledge and is responsible for originating and managing the transaction, other investment professional(s) who perform due diligence, credit and corporate financial analyses and, as needed, our Chief Legal Officer. To ensure consistent underwriting, we generally use our standardized due diligence methodologies, which include due diligence on financial performance and credit risk as well as an analysis of the operations, accounting policies and the legal and applicable regulatory framework of a prospective portfolio company. The members of the underwriting team work together to conduct due diligence and understand the relationships among the prospective portfolio company’s business plan, operations and financial performance.

As part of our evaluation of a proposed investment, the underwriting team prepares an investment memorandum for presentation to the investment committee. In preparing the investment memorandum, the underwriting team typically meets with select key management of the company and select financial sponsors and assembles information necessary to the investment decision. If and when appropriate, the investment professionals may also contact industry experts and customers, vendors or, in some cases, competitors of the company.

Approval Process. The sponsoring managing director or principal presents the investment memorandum to our investment committee for consideration. The unanimous approval of our investment committee is required before we proceed with any investment. The members of our investment committee are our Chief Executive Officer, our Chief Legal Officer and our Chief Financial Officer. The investment committee generally meets weekly and more frequently on an as-needed basis.

Documentation

Our documentation group, headed by our Chief Legal Officer, administers the front-end documentation process for our loans. This group is responsible for documenting the term sheet approved by the investment committee to memorialize the transaction with a portfolio company. This group negotiates loan documentation and, subject to the approval of the Chief Legal Officer, final documents are prepared for execution by all parties. The documentation group generally uses the services of external law firms to complete the necessary documentation.

Loan and Compliance Administration

Our loan and compliance administration group, headed by our Chief Financial Officer, administers loans and tracks covenant compliance on our investments and oversees periodic reviews of our critical functions to ensure adherence with our internal policies and procedures. After funding of a loan in accordance with the investment committee’s approval, the loan is recorded in our SQL-based database system. The loan and compliance administration group is also responsible for ensuring timely interest and principal payments and collateral management and advises the investment committee on the financial performance and trends of each portfolio company, including any covenant violations that occur, to aid us in assessing the appropriate course of action for each portfolio company and evaluating overall portfolio quality. In addition, the loan and compliance administration group advises the Valuation Committee of the board regarding the credit and investment grading for each portfolio company as well as changes in the value of collateral that may occur.

The loan and compliance administration group monitors our portfolio companies in order to determine whether the companies are meeting our financing criteria and their respective business plans and also monitors

11

Table of Contents

the financial trends of each portfolio company from its monthly or quarterly financial statements to assess the appropriate course of action for each company and to evaluate overall portfolio quality. In addition, our management team closely monitors the status and performance of each individual company through our SQL-based database system and periodic contact with our portfolio companies’ management teams and their respective financial sponsors.

Credit and Investment Grading System. Our loan and compliance administration group uses an investment grading system to characterize and monitor our outstanding loans. Our loan and compliance administration group monitors and, when appropriate, recommends changes to investment grading. Our investment committee reviews the recommendations and/or changes to the investment grading, which are submitted on a quarterly basis to the Valuation Committee and our Board of Directors for approval. We use the following investment grading system as amended January 2006 and approved by our Board of Directors:

At December 31, 2006, our investments had a weighted average investment grading of 2.14.

Managerial Assistance

As a business development company, we offer, and provide upon request, managerial assistance to our portfolio companies. This assistance could involve, among other things, monitoring the operations of our portfolio companies, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance. We may receive fees for these services.

Asset Management

We may engage in the asset management business by providing investment advisory services to funds that may be formed in the future. Such funds may focus on our lower yielding assets, such as senior debt, equipment based only financing or equity only funding. We may contribute assets currently in our portfolio to the extent that our management and Board of Directors deems it appropriate. We may, from time to time, serve as the

12

Table of Contents

investment manager of such funds and may receive management and other fees for such services. Such funds may have overlapping investment objectives and may invest in asset classes similar to those targeted by us.

Competition

Our primary competitors provide financing to prospective portfolio companies and include non-bank financial institutions, federally or state chartered banks, venture debt funds, financial institutions, venture capital funds, private equity funds, investment funds and investment banks. Many of these entities have greater financial and managerial resources than we have, and the 1940 Act imposes certain regulatory restrictions on us as a business development company to which many of our competitors are not subject. However, we believe that few of our competitors possess the expertise to properly structure and price debt investments to venture capital and private equity backed technology-related companies. We believe that our specialization in financing technology-related companies will enable us to assess the value of intellectual property assets, evaluate the business prospects and operating characteristics of prospective portfolio companies and, as a result, identify investment opportunities that produce attractive risk-adjusted returns. For additional information concerning the competitive risks we face, see “Risk Factors—Risks Related to our Business and Structure—We operate in a highly competitive market for investment opportunities, and we may not be able to compete effectively.”

Corporate Structure

We are a Maryland corporation and an internally-managed, non-diversified closed-end investment company that has elected to be regulated as a business development company under the 1940 Act. Hercules Technology II, L.P. (“HTII”), our wholly-owned subsidiary, is licensed under the Small Business Investment Act of 1958 as a Small Business Investment Company. Hercules Technology SBIC Management, LLC (“HTM”), another wholly-owned subsidiary, functions as the general partner of our subsidiary HTII. Hercules Funding I LLC, our wholly owned subsidiary, and Hercules Funding Trust I function as vehicles to collateralize loans under our securitized credit facility with Citigroup Global Markets Realty Corp. In December 2006, we established Hydra Management LLC and Hydra Management Co., Inc. an investment manager and an investment management company, respectively.

Our principal executive offices are located at 400 Hamilton Avenue, Suite 310, Palo Alto, California 94301. We also have offices in Boston, Massachusetts, Boulder, Colorado, Chicago, Illinois and Columbus, Ohio.

Brokerage Allocations and Other Practices

Because we generally acquire and dispose of our investments in privately negotiated transactions, we rarely use brokers in the normal course of business. In those cases where we do use a broker, we do not execute transactions through any particular broker or dealer, but will seek to obtain the best net results for Hercules, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While we generally seek reasonably competitive execution costs, we may not necessarily pay the lowest spread or commission available. Subject to applicable legal requirements, we may select a broker based partly upon brokerage or research services provided to us. In return for such services, we may pay a higher commission than other brokers would charge if we determine in good faith that such commission is reasonable in relation to the services provided. For the years ended December 31, 2006, 2005 and 2004 we paid $12,100, $4,000 and $0 in brokerage commissions, respectively.

Employees

As of December 31, 2006, we had 26 employees, including 15 investment and portfolio management professionals all of whom have extensive prior experience working on financing transactions for technology-

related companies. We intend to expand our management team, financial analyst group and operational personnel to support our growing portfolio of companies. We may also hire additional managing directors if our business indicates the need to expand the team to take advantage of growing market opportunities.

REGULATION AS A BUSINESS DEVELOPMENT COMPANY

The following discussion is a general summary of the material prohibitions and descriptions governing business development companies generally. It does not purport to be a complete description of all of the laws and regulations affecting business development companies.

A business development company is a unique kind of investment company that primarily focuses on investing in or lending to private companies and making managerial assistance available to them. A business development company provides stockholders with the ability to retain the liquidity of a publicly-traded stock, while sharing in the possible benefits of investing in emerging-growth or expansion-stage privately-owned companies. The 1940 Act contains prohibitions and restrictions relating to transactions between business development companies and their directors and officers and principal underwriters and certain other related persons and requires that a majority of the directors be persons other than “interested persons,” as that term is defined in the 1940 Act. In addition, the 1940 Act provides that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a business development company unless approved by a majority of our outstanding voting securities. A majority of the outstanding voting securities of a company is defined under the 1940 Act as the lesser of: (i) 67% or more of such company’s shares present at a meeting if more than 50% of the outstanding shares of such company are present or represented by proxy, or (ii) more than 50% of the outstanding shares of such company.

Qualifying Assets

Under the 1940 Act, a business development company may not acquire any asset other than assets of the type listed in Section 55(a) of the 1940 Act, which are referred to as qualifying assets, unless, at the time the acquisition is made, qualifying assets represent at least 70% of the company’s total assets. The principal categories of qualifying assets relevant to our proposed business are the following:

14

Table of Contents

Significant Managerial Assistance

In order to count portfolio securities as qualifying assets for the purpose of the 70% test, the business development company must either control the issuer of the securities or must offer to make available significant managerial assistance; except that, where the business development company purchases such securities in conjunction with one or more other persons acting together, one of the other persons in the group may make available such managerial assistance. Making available significant managerial assistance means, among other things, any arrangement whereby the business development company, through its directors, officers or employees, offers to provide and, if accepted, does so provide, significant guidance and counsel concerning the management, operations or business objectives and policies of a portfolio company through monitoring of portfolio company operations, selective participation in board and management meetings, consulting with and advising a portfolio company’s officers or other organizational or financial guidance.

Temporary Investments

Pending investment in other types of qualifying assets, as described above, our investments may consist of cash, cash equivalents, U.S. government securities or high quality debt securities maturing in one year or less from the time of investment, which we refer to, collectively, as temporary investments, so that 70% of our assets are qualifying assets. Typically, we invest in U.S. treasury bills or in repurchase agreements, provided that such agreements are fully collateralized by cash or securities issued by the U.S. government or its agencies. A repurchase agreement involves the purchase by an investor, such as us, of a specified security and the simultaneous agreement by the seller to repurchase it at an agreed upon future date and at a price which is greater than the purchase price by an amount that reflects an agreed-upon interest rate. There is no percentage restriction on the proportion of our assets that may be invested in such repurchase agreements. However, if more than 25% of our total assets constitute repurchase agreements from a single counterparty, we would not meet the diversification tests imposed on us by the Code in order to qualify as a RIC for federal income tax purposes. Thus, we do not intend to enter into repurchase agreements with a single counterparty in excess of this limit. We will monitor the creditworthiness of the counterparties with which we enter into repurchase agreement transactions.

Warrants and Options

Under the 1940 Act, a business development company is subject to restrictions on the amount of warrants, options or rights to purchase shares of capital stock that it may have outstanding at any time. In particular, the amount of capital stock that would result from the conversion or exercise of all outstanding warrants, options or rights to purchase capital stock cannot exceed 25% of the business development company’s total outstanding shares of capital stock. This amount is reduced to 20% of the business development company’s total outstanding shares of capital stock if the amount of warrants, options or rights issued pursuant to an executive compensation plan would exceed 15% of the business development company’s total outstanding shares of capital stock.

Senior Securities; Coverage Ratio

We will be permitted, under specified conditions, to issue multiple classes of indebtedness and one class of stock senior to our common stock if our asset coverage, as defined in the 1940 Act, is at least equal to 200% immediately after each such issuance. In addition, while any senior securities remain outstanding, we must make provisions to prohibit any dividend distribution to our stockholders or the repurchase of such securities or shares

15

Table of Contents

unless we meet the applicable asset coverage ratios at the time of the dividend distribution or repurchase. We may also borrow amounts up to 5% of the value of our total assets for temporary or emergency purposes. For a discussion of the risks associated with the resulting leverage, see “Risk Factors—Because we borrow money, there could be increased risk in investing in our company.”

Code of Ethics

We have adopted and will maintain a code of ethics pursuant to Rule 17j-1 under the 1940 Act that establishes procedures for personal investments and restricts certain personal securities transactions. Personnel subject to the code may invest in securities for their personal investment accounts, including securities that may be purchased or held by us, so long as such investments are made in accordance with the code’s requirements. Our code of ethics will generally not permit investments by our employees in securities that may be purchased or held by us. We may be prohibited under the 1940 Act from conducting certain transactions with our affiliates without the prior approval of our directors who are not interested persons and, in some cases, the prior approval of the SEC.

Our code of ethics was filed with the SEC as an exhibit to the registration statement (Registration No. 333-126604) for our initial public offering. You may read and copy the code of ethics at the SEC’s Public Reference Room in Washington, D.C. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-202-942-8090. In addition, the code of ethics is available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov. You may obtain copies of the code of ethics, after paying a duplicating fee, by electronic request at the following email address: publicinfo@sec.gov, or by writing the SEC’s Public Reference Section, Washington, D.C. 20549.

Privacy Principles

We are committed to maintaining the privacy of our stockholders and safeguarding their non-public personal information. The following information is provided to help you understand what personal information we collect, how we protect that information and why, in certain cases, we may share information with select other parties.

Generally, we do not receive any non-public personal information relating to our stockholders, although certain non-public personal information of our stockholders may become available to us. We do not disclose any non-public personal information about our stockholders or former stockholders to anyone, except as permitted by law or as is necessary in order to service stockholder accounts (for example, to a transfer agent).

We restrict access to non-public personal information about our stockholders to our employees with a legitimate business need for the information. We maintain physical, electronic and procedural safeguards designed to protect the non-public personal information of our stockholders.

Proxy Voting Policies and Procedures

We vote proxies relating to our portfolio securities in the best interest of our stockholders. We review on a case-by-case basis each proposal submitted to a stockholder vote to determine its impact on the portfolio securities held by us. Although we generally vote against proposals that may have a negative impact on our portfolio securities, we may vote for such a proposal if there exists compelling long-term reasons to do so.

Our proxy voting decisions are made by our investment committee, which is responsible for monitoring each of our investments. To ensure that our vote is not the product of a conflict of interest, we require that: (i) anyone involved in the decision making process disclose to our Chief Compliance Officer any potential conflict that he or she is aware of and any contact that he or she has had with any interested party regarding a

16

Table of Contents

proxy vote; and (ii) employees involved in the decision making process or vote administration are prohibited from revealing how we intend to vote on a proposal in order to reduce any attempted influence from interested parties.

Exemptive Relief

On June 21, 2005, we filed a request with the SEC for exemptive relief to allow us to take certain actions that would otherwise be prohibited by the 1940 Act, as applicable to business development companies. Specifically, we requested that the SEC permit us to issue stock options to our non-employee directors as contemplated by Section 61(a)(3)(B)(i)(II) of the 1940 Act. On February 15, 2007, we received approval from the SEC on this exemptive request.

On September 28, 2005, we filed an exemptive relief application requesting that the SEC permit us to exclude the indebtedness that our wholly-owned subsidiary, HTII, which is qualified as a small business investment company, issues to the Small Business Administration from the 200% asset coverage requirement applicable to us. We filed our final application on March 5, 2007 and are awaiting receipt. In addition, on July 7, 2006, we requested exemptive relief from the SEC to permit us to grant restricted stock and dividend equivalent rights on options to our officers, employees and directors. However, we cannot provide any assurance that we will receive any such exemptive relief.

Other

We will be periodically examined by the SEC for compliance with the 1934 Act and the 1940 Act.

We are required to provide and maintain a bond issued by a reputable fidelity insurance company to protect us against larceny and embezzlement. Furthermore, as a business development company, we are prohibited from protecting any director or officer against any liability to our stockholders arising from willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such person’s office.

We are required to adopt and implement written policies and procedures reasonably designed to prevent violation of the federal securities laws, review these policies and procedures annually for their adequacy and the effectiveness of their implementation. We have designated Mr. Harvey, our Chief Legal Officer, as our Chief Compliance Officer who is responsible for administering these policies and procedures.

Small Business Administration Regulations

HTII, our wholly-owned subsidiary, is licensed by the Small Business Administration (“SBA”) as a small business investment company (SBIC) under Section 301(c) of the Small Business Investment Act of 1958. The Small Business Investment Company regulations currently limit the amount that is available to borrow by any SBIC to $124.4 million, subject to periodic adjustments by the SBA. There is no assurance that we will draw up to the maximum limit available under the Small Business Investment Company program.

Small business investment companies are designed to stimulate the flow of private equity capital to eligible small businesses. Under present Small Business Administration regulations, eligible small businesses include businesses that have a tangible net worth not exceeding $18 million and have average annual fully taxed net income not exceeding $6 million for the two most recent fiscal years. In addition, a small business investment company must devote 20% of its investment activity to “smaller” concerns as defined by the Small Business Administration. A smaller concern is one that has a tangible net worth not exceeding $6 million and has average annual fully taxed net income not exceeding $2 million for the two most recent fiscal years. Small Business Administration regulations also provide alternative size standard criteria to determine eligibility, which depend on the industry in which the business is engaged and are based on such factors as the number of employees and

17

Table of Contents

gross sales. According to Small Business Administration regulations, small business investment companies may make long-term loans to small businesses, invest in the equity securities of such businesses and provide them with consulting and advisory services. Through our wholly-owned subsidiary HTII, we plan to provide long-term loans to qualifying small businesses, and in connection therewith, make equity investments.

HTII will be periodically examined and audited by the Small Business Administration’s staff to determine its compliance with small business investment company regulations.

In January 2005, we formed HTII and HTM. On September 27, 2006, HTII received final approval to be licensed as a Small Business Investment Company (“SBIC”). HTII is able to borrow funds from the Small Business Administration against eligible pre-approved investments and additional deposits to regulatory capital. On January 30, 2007, HTII received notification that its initial application for leverage under its SBC license was approved allowing HTII to commence drawing up to $50.0 million of leverage under its first tranche of capital from the SBA. On March 2, 2007, we filed our first draw request that would allow us to initially borrow up to $12.0 million under the program.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

Conversion to Regulated Investment Company Status

Prior to 2006, we were taxed as a C Corporation under the Code. We operate to qualify as a regulated investment company, or RIC, under Subchapter M of the Code. If we qualify as a regulated investment company and annually distribute to our stockholders in a timely manner at least 90% of our investment company taxable income, we will not be subject to federal income tax on the portion of our taxable income and capital gains we distribute to our shareholders. Taxable income generally differs from net income as defined by generally accepted accounting principles due to temporary and permanent timing differences in the recognition of income and expenses, returns of capital and net unrealized appreciation or depreciation.

We have met the criteria specified below to qualify as a RIC, and will elect to be treated as a RIC under Subchapter M of the Code with the filing of our federal tax return for 2006. The election will be effective as of January 1, 2006. As a RIC, we generally will not have to pay corporate taxes on any income we distribute to our stockholders as dividends, which allows us to reduce or eliminate our corporate level tax. Prior to the effective date of our RIC election, we were taxed as a regular corporation under Subchapter C of the Code. On December 31, 2005, we held assets with “built-in gain,” which are assets whose fair market value as of the effective date of the election exceeds their tax basis. We elected to recognize all of our net built-in gains at the time of the conversion and paid tax on the built-in gain with the filing of our 2005 tax return. In making this election, we marked our portfolio to market at the time of our RIC election and paid approximately $294,000 in tax on the resulting gains.

By December 31, 2006, we were required to distribute our earnings and profits while we were taxable as a C corporation. During 2006, we distributed $1.20 per share to our shareholders of which approximately $0.09 was deemed to be a distribution of these accumulated earnings and profits, $0.97 was deemed to be a distribution of income and $0.14 was a return of capital. The distribution of our income and our accumulated earnings and profits is considered ordinary income to our shareholders in 2006.

Taxation as a Regulated Investment Company

For any taxable year in which we:

18

Table of Contents

we generally will not be subject to federal income tax on the portion of our investment company taxable income and net capital gain (i.e., net realized long-term capital gains in excess of net realized short-term capital losses) we distribute to stockholders with respect to that year. (However, as described above, we will be subject to federal income taxes on certain dispositions of assets that had built-in gains as of the effective date of our conversion to RIC status (unless we elect to be taxed on such gains as of such date). In addition, if we subsequently acquire built-in gain assets from a C corporation in a carryover basis transaction, then we may be subject to tax on the gains recognized by us on dispositions of such assets unless we make a special election to pay corporate-level tax on such built-in gain at the time the assets are acquired.) We will be subject to United States federal income tax at the regular corporate rates on any income or capital gain not distributed (or deemed distributed) to our stockholders.

In order to qualify as a RIC for federal income tax purposes and obtain the tax benefits of RIC status, in addition to satisfying the Annual Distribution Requirement, we must, among other things:

Qualified earnings may exclude such income as management fees received in connection with our SBIC or other potential outside managed funds and certain other fees.

As a RIC, we will be subject to a 4% nondeductible federal excise tax on certain undistributed income unless we distribute in a timely manner an amount at least equal to the sum of (1) 98% of our ordinary income for each calendar year, (2) 98% of our capital gain net income for the 1-year period ending October 31 in that calendar year and (3) any income realized, but not distributed, in the preceding year (the “Excise Tax Avoidance Requirement”). We will not be subject to excise taxes on amounts on which we are required to pay corporate income tax (such as retained net capital gains). We currently intend to make sufficient distributions each taxable year to satisfy the Excise Tax Avoidance Requirement.

We may be required to recognize taxable income in circumstances in which we do not receive cash. For example, if we hold debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments with payment-in-kind interest or, in certain cases, increasing interest rates or issued with warrants), we must include in income each year a portion of the original issue discount that accrues over the life of the obligation, regardless of whether cash representing such income is received by us in the same taxable year. Because any original issue discount accrued will be included in our investment company taxable income for the year of accrual, we may be required to make a distribution to our stockholders in order to satisfy the Annual Distribution Requirement, even though we will not have received any corresponding cash amount.

19

Table of Contents

Gain or loss realized by us from the sale or exchange of warrants acquired by us as well as any loss attributable to the lapse of such warrants generally will be treated as capital gain or loss. Such gain or loss generally will be long-term or short-term, depending on how long we held a particular warrant.

We are authorized to borrow funds and to sell assets in order to satisfy the Annual Distribution Requirement and the Excise Tax Avoidance Requirement (collectively, the “Distribution Requirements”). However, under the 1940 Act, we are not permitted to make distributions to our stockholders while our debt obligations and other senior securities are outstanding unless certain “asset coverage” tests are met. See “Regulation — Senior Securities; Coverage Ratio.” Moreover, our ability to dispose of assets to meet the Distribution Requirements may be limited by (1) the illiquid nature of our portfolio, or (2) other requirements relating to our status as a RIC, including the Diversification Tests. If we dispose of assets in order to meet the Distribution Requirements, we may make such dispositions at times that, from an investment standpoint, are not advantageous.

Any transactions in options, futures contracts, hedging transactions, and forward contracts will be subject to special tax rules, the effect of which may be to accelerate income to us, defer losses, cause adjustments to the holding periods of our investments, convert long-term capital gains into short-term capital gains, convert short-term capital losses into long-term capital losses or have other tax consequences. These rules could affect the amount, timing and character of distributions to stockholders. We do not currently intend to engage in these types of transactions.

A RIC is limited in its ability to deduct expenses in excess of its “investment company taxable income” (which is, generally, ordinary income plus net realized short-term capital gains). If our expenses in a given year exceed gross taxable income (e.g., as the result of large amounts of equity-based compensation), we would experience a net operating loss for that year. However, a RIC is not permitted to carry forward net operating losses to subsequent years. In addition, expenses can be used only to offset investment company taxable income, not net capital gain. Due to these limits on the deductibility of expenses, we may for tax purposes have aggregate taxable income for several years that we are required to distribute and that is taxable to our stockholders even if such income is greater than the aggregate net income we actually earned during those years. Such required distributions may be made from our cash assets or by liquidation of investments, if necessary. We may realize gains or losses from such liquidations. In the event we realize net capital gains from such transactions, you may receive a larger capital gain distribution than you would have received in the absence of such transactions.

Failure to Qualify as a Regulated Investment Company

If we were unable to qualify for treatment as a RIC, we would be subject to tax on all of our taxable income at regular corporate rates. We would not be able to deduct distributions to stockholders, nor would they be required to be made. Such distributions (if made in a taxable year beginning on or before December 31, 2008) would be taxable to our stockholders and, provided certain holding period and other requirements were met, could qualify for treatment as “qualified dividend income” eligible for the 15% maximum rate to the extent of our current and accumulated earnings and profits. Subject to certain limitations under the Code, corporate distributees would be eligible for the dividends-received deduction. Distributions in excess of our current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder’s tax basis, and any remaining distributions would be treated as a capital gain. To requalify as a RIC in a subsequent taxable year, we would be required to satisfy the RIC qualification requirements for that year and dispose of any earnings and profits from any year in which we failed to qualify as a RIC. Subject to a limited exception applicable to RICs that qualified as such under Subchapter M of the Code for at least one year prior to disqualification and that requalify as a RIC no later than the second year following the nonqualifying year, we could be subject to tax on any unrealized net built-in gains in the assets held by us during the period in which we failed to qualify as a RIC that are recognized within the subsequent 10 years, unless we made a special election to pay corporate-level tax on such built-in gain at the time of our requalification as a RIC.

DETERMINATION OF NET ASSET VALUE

We determine the net asset value per share of our common stock quarterly. The net asset value per share is equal to the value of our total assets minus liabilities and any preferred stock outstanding divided by the total number of shares of common stock outstanding. As of the date of this report, we do not have any preferred stock outstanding.

At December 31, 2006, approximately 94% of our total assets represented investments in portfolio companies recorded at fair value. Value, as defined in Section 2(a) (41) of the 1940 Act, is (i) the market price for those securities for which a market quotation is readily available and (ii) for all other securities and assets, fair value is as determined in good faith by the Board of Directors in accordance with established valuation procedures and the recommendation of the Valuation Committee of the Board of Directors. Since there is typically no readily available market value for the investments in our portfolio, we value substantially all of our investments at fair value as determined in good faith by our management pursuant to a valuation policy and a consistent valuation process. Due to the inherent uncertainty in determining the fair value of investments that do not have a readily available market value, the fair value of our investments determined in good faith by our management may differ significantly from the value that would have been used had a ready market existed for such investments, and the differences could be material.

There is no single standard for determining fair value in good faith. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment. Unlike banks, we are not permitted to provide a general reserve for anticipated loan losses. Instead, we must determine the fair value of each individual investment on a quarterly basis. We will record unrealized depreciation on investments when we believe that an investment has decreased in value, including where collection of a loan or realization of an equity security is doubtful. Conversely, we will record unrealized appreciation if we believe that the underlying portfolio company has appreciated in value and, therefore, our investment has also appreciated in value, where appropriate.

As a business development company, we invest primarily in illiquid securities including debt and equity-related securities of private companies. Our investments are generally subject to some restrictions on resale and generally have no established trading market. Because of the type of investments that we make and the nature of our business, our valuation process requires an analysis of various factors. Our valuation methodology includes the examination of, among other things, the underlying investment performance, financial condition and market changing events that impact valuation.

When a qualifying external event such as a significant purchase transaction, public offering, or subsequent debt or equity sale occurs, the pricing indicated by the external event will be used to corroborate our private debt or equity valuation. Securities that are traded in the over-the-counter market or on a stock exchange will be valued at the prevailing bid price on the valuation date.

Determinations in Connection with Offerings

In connection with each offering of shares of our common stock, our Board of Directors or a committee thereof is required to make the determination that we are not selling shares of our common stock at a price below the then current net asset value of our common stock at the time at which the sale is made. Our Board of Directors considers the following factors, among others, in making such determination:

21

Table of Contents

Importantly, this determination does not require that we calculate the net asset value of our common stock in connection with each offering of shares of our common stock, but instead it involves the determination by our Board of Directors or a committee thereof that we are not selling shares of our common stock at a price below the then current net asset value of our common stock at the time at which the sale is made.

Moreover, to the extent that there is even a remote possibility that we may (i) issue shares of our common stock at a price below the then current net asset value of our common stock at the time at which the sale is made or (ii) trigger the undertaking (which we provide to the SEC in the registration statement relating to an offering of common stock) to suspend the offering of shares of our common stock if the net asset value of our common stock fluctuates by certain amounts in certain circumstances until the prospectus relating to such offering is amended, our Board of Directors will elect, in the case of clause (i) above, either to postpone the offering until such time that there is no longer the possibility of the occurrence of such event or to undertake to determine the net asset value of our common stock within two days prior to any such sale to ensure that such sale will not be below our then current net asset value, and, in the case of clause (ii) above, to comply with such undertaking or to undertake to determine the net asset value of our common stock to ensure that such undertaking has not been triggered.

These processes and procedures are part of our compliance policies and procedures. Records will be made contemporaneously with all determinations described in this section and these records will be maintained with other records we are required to maintain under the 1940 Act.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider carefully the risks described below and all other information contained in this Annual Report, including our financial statements and the related notes and the schedules and exhibits to this Annual Report.

Risks Related to our Business and Structure

We have a limited operating history as a business development company, which may affect our ability to manage our business and may impair your ability to assess our prospects.

We were incorporated in December 2003 and commenced investment operations in September 2004. We are subject to all of the business risks and uncertainties associated with any new business enterprise, including the risk that we will not achieve our investment objective and that the value of our common stock could decline substantially. We have a limited operating history as a business development company. As a result, we have limited operating results under these regulatory frameworks that can demonstrate to you either their effect on the business or our ability to manage the business within these frameworks. If we fail to maintain our status as a business development company or fail to qualify as a RIC, our operating flexibility and results of operations would be significantly affected.

22

Table of Contents

We are dependent upon key management personnel for our future success, particularly Manuel A. Henriquez, and if we are not able to hire and retain qualified personnel, or if we lose any member of our senior management team, our ability to implement our business strategy could be significantly harmed.

We depend upon the members of our senior management, particularly Mr. Henriquez, as well as other key personnel for the identification, final selection, structuring, closing and monitoring of our investments. These employees have critical industry experience and relationships on which we rely to implement our business plan. If we lose the services of Mr. Henriquez, or of any other senior management members, we may not be able to operate the business as we expect, and our ability to compete could be harmed, which could cause our operating results to suffer. We believe our future success will depend, in part, on our ability to identify, attract and retain sufficient numbers of highly skilled employees. If we do not succeed in identifying, attracting and retaining such personnel, we may not be able to operate our business as we expect.

Our business model depends to a significant extent upon strong referral relationships with venture capital and private equity fund sponsors, and our inability to develop or maintain these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business.

We expect that members of our management team will maintain their relationships with venture capital and private equity firms, and we will rely to a significant extent upon these relationships to provide us with our deal flow. If we fail to maintain our existing relationships or to develop new relationships with other firms or sources of investment opportunities, then we will not be able to grow our investment portfolio. In addition, persons with whom members of our management team have relationships are not obligated to provide us with investment opportunities and, therefore, there is no assurance that such relationships will lead to the origination of debt or other investments.

We operate in a highly competitive market for investment opportunities, and we may not be able to compete effectively.

A large number of entities compete with us to make the types of investments that we plan to make in prospective portfolio companies. We compete with a large number of venture capital and private equity firms, as well as with other investment funds, investment banks and other sources of financing, including traditional financial services companies such as commercial banks and finance companies. Many of our competitors are substantially larger and have considerably greater financial, technical, marketing and other resources than we do. For example, some competitors may have a lower cost of funds and/or access to funding sources that are not available to us. This may enable some competitors to make commercial loans with interest rates that are comparable to or lower than the rates that we typically offer. We may lose prospective portfolio companies if we do not match competitors’ pricing, terms and structure. If we do match competitors’ pricing, terms or structure, we may experience decreased net interest income and increased risk of credit losses. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments, establish more relationships and build their market shares. Furthermore, many potential competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a business development company or that the Code would impose on us as a RIC. If we are not able to compete effectively, our business, financial condition, and results of operations will be adversely affected. As a result of this competition, there can be no assurance that we will be able to identify and take advantage of attractive investment opportunities that we identify, or that we will be able to fully invest our available capital.

Because we intend to distribute substantially all of our income to our stockholders in order to qualify as a RIC, we will continue to need additional capital to finance our growth. If additional funds are unavailable or not available on favorable terms, our ability to grow will be impaired.

In order to satisfy the tax requirements applicable to a RIC, to avoid payment of excise taxes and to minimize or avoid payment of income taxes, we intend to distribute to our stockholders substantially all of our

23

Table of Contents

ordinary income and realized net capital gains except for certain realized net long-term capital gains, which we currently intend to retain, pay applicable income taxes with respect thereto and elect to treat as deemed distributions to our stockholders. As a business development company, we generally are required to meet a coverage ratio of total assets to total borrowings and other senior securities, which includes all of our borrowings and any preferred stock that we may issue in the future, of at least 200%. This requirement limits the amount that we may borrow. Because we will continue to need capital to grow our loan and investment portfolio, this limitation may prevent us from incurring debt and require us to raise additional equity at a time when it may be disadvantageous to do so. While we expect to be able to borrow and to issue additional debt and equity securities, we cannot assure you that debt and equity financing will be available to us on favorable terms, or at all, and debt financings may be restricted by the terms of any of our outstanding borrowings. In addition, as a business development company, we generally are not permitted to issue equity securities priced below net asset value without stockholder approval and approval of our independent directors. If additional funds are not available to us, we could be forced to curtail or cease new lending and investment activities, and our net asset value could decline.

Because we borrow money, there could be increased risk in investing in our company.

Lenders have fixed dollar claims on our assets that are superior to the claims of stockholders, and we have granted, and may in the future grant, lenders a security interest in our assets in connection with borrowings. In the case of a liquidation event, those lenders would receive proceeds before our stockholders. In addition, borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our securities. Leverage is generally considered a speculative investment technique. If the value of our assets increases, then leveraging would cause the net asset value attributable to our common stock to increase more than it otherwise would have had we not leveraged. Conversely, if the value of our assets decreases, leveraging would cause the net asset value attributable to our common stock to decline more than it otherwise would have had we not leveraged. Similarly, any increase in our revenue in excess of interest expense on our borrowed funds would cause our net income to increase more than it would without the leverage. Any decrease in our revenue would cause our net income to decline more than it would have had we not borrowed funds and could negatively affect our ability to make distributions on common stock. Our ability to service any debt that we incur will depend largely on our financial performance and will be subject to prevailing economic conditions and competitive pressures. We and, indirectly our stockholders will bear the cost associated with our leverage activity. Our securitized credit facility with Citigroup Global Markets Realty Corp. which we refer to as the Citigroup Facility contains financial and operating covenants that could restrict our business activities, including our ability to declare dividends if we default under certain provisions.

As of December 31, 2006, we had outstanding indebtedness of $41 million pursuant to our securitized credit facility with Citigroup Global Market Realty Corp., which we refer to as the Citigroup Facility. We expect, in the future, to borrow from, and issue senior debt securities to, banks, insurance companies and other lenders, including additional borrowings pursuant to the Citigroup Facility. See “Management’s Discussion and Analysis of Financial Condition—Borrowings.” In addition, we expect to continue to pursue financing from the Small Business Administration under its Small Business Investment Company program. See “Regulation—Small Business Administration Regulations.”

As a business development company, we generally are required to meet a coverage ratio of total assets to total borrowings and other senior securities, which include all of our borrowings and any preferred stock that we may issue in the future, of at least 200%. If this ratio declines below 200%, we may not be able to incur additional debt and may need to sell a portion of our investments to repay some debt when it is disadvantageous to do so, and we may not be able to make distributions.

Because most of our investments typically are not in publicly-traded securities, there is uncertainty regarding the value of our investments, which could adversely affect the determination of our net asset value.

At December 31, 2006, portfolio investments, 99% of which are valued at fair value by the Board of Directors were approximately 94% of our total assets. We expect our investments to continue to consist primarily of securities issued by privately-held companies, the fair value of which is not readily determinable. In addition, we are not permitted to maintain a general reserve for anticipated loan losses. Instead, we are required by the 1940 Act to specifically value each investment and record an unrealized gain or loss for any asset that we believe has increased or decreased in value. There is no single standard for determining fair value in good faith. We value these securities at fair value as determined in good faith by our Board of Directors, based on the recommendations of our Valuation Committee. The Valuation Committee uses its best judgment in arriving at the fair value of these securities. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment while employing a consistently applied valuation process for the types of investments we make. However, the Board of Directors retains ultimate authority as to the appropriate valuation of each investment. Because such valuations are inherently uncertain and may be based on estimates, our determinations of fair value may differ materially from the values that would be assessed if a ready market for these securities existed. We adjust quarterly the valuation of our portfolio to reflect the Board of Directors’ determination of the fair value of each investment in our portfolio. Any changes in fair value are recorded in our statement of operations as net change in unrealized appreciation or depreciation. Our net asset value could be adversely affected if our determinations regarding the fair value of our investments were materially higher than the values that we ultimately realize upon the disposal of such securities.

Our financial results could be negatively affected if a significant portfolio investment fails to perform as expected.

Our total investment in companies may be significant individually or in the aggregate. As a result, if a significant investment in one or more companies fails to perform as expected, our financial results could be more negatively affected and the magnitude of the loss could be more significant than if we had made smaller investments in more companies. The following table shows the fair value of investments held at December 31, 2006 that are greater than 5% of net assets:

QuatRx Pharmaceuticals Company is a pharmaceutical company focused on discovering, licensing, developing and commercializing compounds in the endocrine, metabolic and cardiovascular therapeutic areas.

AVEO is a biopharmaceutical company focused on the discovery and development of novel cancer therapeutics.

Luminus Devices, Inc. develops and manufactures high performance solid state light emitting devices, leading the industry in designing and manufacturing new, powerful light source for a variety of applications.

WageWorks provides employer-sponsored, tax-advantaged spending solutions, including medical and family-care reimbursement and transit passes.

Our financial results could be negatively affected if these portfolio companies or any of our other significant portfolio companies encounter financial difficulty and fail to repay their obligations or to perform as expected.

Regulations governing our operations as a business development company affect our ability to, and the manner in which, we raise additional capital, which may expose us to risks.

Our business will require a substantial amount of capital. We may acquire additional capital from the issuance of senior securities, including borrowings, securitization transactions or other indebtedness, or the issuance of additional shares of our common stock. However, we may not be able to raise additional capital in the future on favorable terms or at all. We may issue debt securities, other evidences of indebtedness or preferred stock, and we may borrow money from banks or other financial institutions, which we refer to collectively as “senior securities,” up to the maximum amount permitted by the 1940 Act. The 1940 Act permits us to issue senior securities in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after each issuance of senior securities. Our ability to pay dividends or issue additional senior securities would be restricted if our asset coverage ratio were not at least 200%. If the value of our assets declines, we may be unable to satisfy this test. If that happens, we may be required to liquidate a portion of our investments and repay a portion of our indebtedness at a time when such sales may be disadvantageous. As a result of issuing senior securities, we would also be exposed to typical risks associated with leverage, including an increased risk of loss. If we issue preferred stock, the preferred stock would rank “senior” to common stock in our capital structure, preferred stockholders would have separate voting rights and might have rights, preferences, or privileges more favorable than those of our common stockholders and the issuance of preferred stock could have the effect of delaying, deferring, or preventing a transaction or a change of control that might involve a premium price for holders of our common stock or otherwise be in your best interest.

To the extent that we are constrained in our ability to issue debt or other senior securities, we will depend on issuances of common stock to finance operations. Other than in certain limited situations such as rights offerings, as a business development company, we are generally not able to issue our common stock at a price below net asset value without first obtaining required approvals from our stockholders and our independent directors. If we raise additional funds by issuing more common stock or senior securities convertible into, or exchangeable for, our common stock, then the percentage ownership of our stockholders at that time will decrease, and you might experience dilution. In addition to issuing securities to raise capital as described above, we anticipate that, in the future, we may securitize our loans to generate cash for funding new investments. An inability to successfully securitize our loan portfolio could limit our ability to grow our business and fully execute our business strategy.

When we are a debt or minority equity investor in a portfolio company, we may not be in a position to control the entity, and management of the company may make decisions that could decrease the value of our portfolio holdings.

We make both debt and minority equity investments; therefore, we are subject to the risk that a portfolio company may make business decisions with which we disagree, and the stockholders and management of such company may take risks or otherwise act in ways that do not serve our interests. As a result, a portfolio company may make decisions that could decrease the value of our portfolio holdings.

If we do not invest a sufficient portion of our assets in qualifying assets, we could fail to qualify as a business development company or be precluded from investing according to our current business strategy.

As a business development company, we may not acquire any assets other than “qualifying assets” unless, at the time of and after giving effect to such acquisition, at least 70% of our total assets are qualifying assets. See “Regulation.”

We believe that most of the senior and mezzanine loans investments will constitute qualifying assets. However, we may be precluded from investing in what we believe are attractive investments if such investments are not qualifying assets for purposes of the 1940 Act. If we do not invest a sufficient portion of our assets in qualifying assets, we could lose our status as a business development company, which would have a material adverse effect on our business, financial condition and results of operations. Similarly, these rules could prevent us from making follow-on investments in existing portfolio companies (which could result in the dilution of our

26

Table of Contents

position) or could require us to dispose of investments at inappropriate times in order to comply with the 1940 Act. If we need to dispose of such investments quickly, it would be difficult to dispose of such investments on favorable terms. For example, we may have difficulty in finding a buyer and, even if we do find a buyer, we may have to sell the investments at a substantial loss.

We may have difficulty paying our required distributions if we recognize income before or without receiving cash representing such income.

In accordance with generally accepted accounting principles and tax requirements, we include in income certain amounts that we have not yet received in cash, such as contracted payment-in-kind interest, which represents contractual interest added to a loan balance and due at the end of such loan’s term. In addition to the cash yields received on our loans, in some instances, certain loans may also include any of the following: end-of-term payments, exit fees, balloon payment fees or prepayment fees. The increases in loan balances as a result of contracted payment-in-kind arrangements are included in income for the period in which such payment-in-kind interest was accrued, which is often in advance of receiving cash payment, and are separately identified on our statements of cash flows. We also may be required to include in income certain other amounts that we will not receive in cash.

Any warrants that we receive in connection with our debt investments will generally be valued as part of the negotiation process with the particular portfolio company. As a result, a portion of the aggregate purchase price for the debt investments and warrants will be allocated to the warrants that we receive. This will generally result in “original issue discount” for tax purposes, which we must recognize as ordinary income, increasing the amount that we are required to distribute to qualify for the federal income tax benefits applicable to RICs. Because these warrants would not produce distributable cash for us at the same time as we are required to make distributions in respect of the related original issue discount, we would need to obtain cash from other sources to satisfy such distribution requirements. If we are unable to obtain cash from other sources to satisfy such distribution requirements, we may fail to qualify for the federal income tax benefits allowable to RICs and, thus, become subject to a corporate-level income tax on all our income.

Other features of the debt instruments that we hold may also cause such instruments to generate an original issue discount, resulting in a dividend distribution requirement in excess of current cash interest received. Since in certain cases we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the RIC tax requirement to distribute at least 90% of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. If we are unable to meet these distribution requirements, we will not qualify for the federal income tax benefits allowable to a RIC. Accordingly, we may have to sell some of our assets, raise additional debt or equity capital or reduce new investment originations to meet these distribution requirements

There is a risk that you may not receive distributions or that our distributions may not grow over time.

We intend to make distributions on a quarterly basis to our stockholders. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. In addition, due to the asset coverage test applicable to us as a business development company, we may be limited in our ability to make distributions. Also, our credit facility limits our ability to declare dividends if we default under certain provisions.

If we are unable to manage our future growth effectively, we may be unable to achieve our investment objective, which could adversely affect our financial condition and results of operations and cause the value of your investment to decline.

Our ability to achieve our investment objective will depend on our ability to sustain growth. Sustaining growth will depend, in turn, on our senior management team’s ability to identify, evaluate, finance and invest in suitable companies that meet our investment criteria. Accomplishing this result on a cost-effective basis is

27

Table of Contents

largely a function of our marketing capabilities, our management of the investment process, our ability to provide efficient services and our access to financing sources on acceptable terms. Failure to manage our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

Our quarterly and annual operating results are subject to fluctuation as a result of the nature of our business, and if we fail to achieve our investment objective, the net asset value of our common stock may decline.

We could experience fluctuations in our quarterly and annual operating results due to a number of factors, some of which are beyond our control, including, but not limited to, the interest rate payable on the debt securities that we acquire, the default rate on such securities, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

In addition, any of these factors could negatively impact our ability to achieve our investment objectives, which may cause our net asset value of our common stock to decline.

Fluctuations in interest rates may adversely affect our profitability.

A portion of our income will depend upon the difference between the rate at which we borrow funds and the interest rate on the debt securities in which we invest. Because we will borrow money to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds and the rate at which we invest these funds. Typically, we anticipate that our interest-earning investments will accrue and pay interest at fixed rates, and that our interest-bearing liabilities will accrue interest at variable rates. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. We anticipate using a combination of equity and long-term and short-term borrowings to finance our investment activities.

A significant increase in market interest rates could harm our ability to attract new portfolio companies and originate new loans and investments. We expect that most of our initial investments in debt securities will be at fixed rates. However, in the event that we make investments in debt securities at variable rates, a significant increase in market interest rates could also result in an increase in our non-performing assets and a decrease in the value of our portfolio because our floating-rate loan portfolio companies may be unable to meet higher payment obligations. In periods of rising interest rates, our cost of funds would increase, resulting in a decrease in our net investment income. In addition, a decrease in interest rates may reduce net income, because new investments may be made at lower rates despite the increased demand for our capital that the decrease in interest rates may produce. We may, but will not be required to, hedge against the risk of adverse movement in interest rates in our short-term and long-term borrowings relative to our portfolio of assets. If we engage in hedging activities, it may limit our ability to participate in the benefits of lower interest rates with respect to the hedged portfolio. Adverse developments resulting from changes in interest rates or hedging transactions could have a material adverse effect on our business, financial condition, and results of operations.

If we are unable to continue to borrow money in order to leverage our equity capital, then our ability to make new investments and to execute our business plan will be impaired.

As of December 31, 2006, we had outstanding borrowings of $41.0 million pursuant to the Citigroup Facility. We expect to incur additional indebtedness under our subsidiary’s small business investment company license from the Small Business Administration. There can be no assurance that we will be successful in obtaining any additional debt capital on terms acceptable to us or at all. If we are unable to obtain debt capital, then our equity investors will not benefit from the potential for increased returns on equity resulting from leverage to the extent that our investment strategy is successful.

In addition, the terms of available financing may place limits on our financial and operating flexibility. If we are unable to obtain sufficient capital in the future, we may:

It is likely that the terms of any long-term or revolving credit or warehouse facility we may enter into in the future could constrain our ability to grow our business.

As of December 31, 2006, the Company, through Hercules Funding Trust I, an affiliated statutory trust, has a $150 million securitized credit facility with Citigroup. We expect to enter into additional revolving credit or warehouse facilities in the future. While there can be no assurance that we will be able to borrow from banks or other financial institutions, we expect that we will, at some time in the future, obtain a long-term or revolving credit facility or a warehouse facility. The current lenders have, and any future lender or lenders will have fixed dollar claims on our assets that are senior to the claims of our stockholders and, thus, will have a preference over our stockholders with respect to our assets. In addition, we may grant a security interest in our assets in connection with any such borrowing. We expect such a facility to contain customary default provisions such as a minimum net worth amount, a profitability test, and a restriction on changing our business and loan quality standards. An event of default under any credit facility would likely result, among other things, in termination of the availability of further funds under that facility and an accelerated maturity date for all amounts outstanding under the facility, which would likely disrupt our business and, potentially, the business of the portfolio companies whose loans that we financed through the facility. This could reduce our revenues and, by delaying any cash payment allowed to us under our facility until the lender has been paid in full, reduce our liquidity and cash flow and impair our ability to grow our business and maintain our status as a RIC.

Our cost of borrowing is increased by the warrant participation agreement we have with one of our lenders. In addition, our realized gains are reduced by amounts paid pursuant to the warrant participation agreement.

Citigroup has an equity participation right through a warrant participation agreement on the pool of loans and warrants collateralized under the Citigroup Facility. Pursuant to the warrant participation agreement, we granted to Citigroup a 10% participation in all warrants held as collateral. As a result, Citigroup is entitled to 10% of the realized gains on the warrants until the realized gains paid to Citigroup pursuant to the agreement equals $3,750,000 (the “Maximum Participation Limit”). The obligations under the warrant participation agreement continue even after the Citigroup Facility is terminated until the Maximum Participation Limit has been reached.

During the year ended December 31, 2006, the Company reduced its realized gain by approximately $221,000 for Citigroup’s participation in the gain on sale of an equity security and recorded an additional liability and reduced its unrealized gains by a net amount of approximately $35,000 for Citigroup’s participation. Since inception of the agreement, we have paid Citigroup approximately $281,000 under the warrant participation agreement thereby reducing our realized gains. In addition, our realized gains will be reduced by the amounts owed to Citigroup under the warrant participation agreement. The value of Citigroup’s participation right on unrealized gains in the related equity investments since inception of the agreement was approximately $377,000 at December 31, 2006 and is included in accrued liabilities and reduces the unrealized gain recognized by us at December 31, 2006. Citigroup’s rights under the warrant participation agreement increase our cost of borrowing and reduce our realized gains.

Table of Contents

One of our wholly-owned subsidiaries is licensed by the U.S. Small Business Administration, and as a result, we will be subject to SBA regulations.

Our wholly-owned subsidiary HTII, is licensed to operate as a SBIC and is regulated by the U.S. Small Business Administration (“SBA”). The SBA regulations require that a licensed SBIC be periodically examined and audited by the SBA to determine its compliance with the relevant SBA regulations. If HTII fails to comply with applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit the HTII’s use of debentures, declare outstanding debentures immediately due and payable, and/or limit the HTII from making new investments. The SBA also imposes a limit on the maximum amount that may be borrowed by any single SBIC. The SBA prohibits, without prior SBA approval, a “change of control” of a SBIC or transfers that would result in any person (or a group of persons acting in concert) owning 10% or more of a class of capital stock of a licensed SBIC.

If we are unable to satisfy Code requirements for qualification as a RIC, then we will be subject to corporate-level income tax, which would adversely affect our results of operations and financial condition.

We will elect to be treated as a RIC for federal income tax purposes with the filing of our federal corporate income tax return for 2006, which election will be effective as of January 1, 2006. We will not qualify for the tax treatment allowable to RICs if we are unable to comply with the source of income, diversification and distribution requirements contained in Subchapter M of the Code, or if we fail to maintain our election to be regulated as a business development company under the 1940 Act. If we fail to qualify for the federal income tax benefits allowable to RICs for any reason and remain or become subject to a corporate-level income tax, the resulting taxes could substantially reduce our net assets, the amount of income available for distribution to our stockholders and the actual amount of our distributions. Such a failure would have a material adverse effect on us, the net asset value of our common stock and the total return, if any, obtainable from your investment in our common stock. Any net operating losses that we incur in periods during which we qualify as a RIC will not offset net capital gains (i.e., net realized long-term capital gains in excess of net realized short-term capital losses) that we are otherwise required to distribute, and we cannot pass such net operating losses through to our stockholders. In addition, net operating losses that we carry over to a taxable year in which we qualify as a RIC normally cannot offset ordinary income or capital gains.

Interpretations of the staff of the Securities and Exchange Commission regarding the appropriateness of the consolidation of certain of our subsidiaries may have an impact on our financial statements.

The staff of the Securities and Exchange Commission (the “Staff”) is reviewing the appropriateness of the consolidation of certain types of subsidiaries on an industry-wide basis under generally accepted accounting principles (“GAAP”) and Rule 6-03 of Regulation S-X. In connection with such review, the Staff is in the process of reviewing the appropriateness of our consolidation of certain of our subsidiaries (the “Subsidiaries”). In the event that the Staff disagrees with our position with respect to the appropriateness of consolidation of any of the Subsidiaries, then we will make such additional disclosures and prospective changes in accounting methods as the Staff requires on a prospective basis which will be discussed and reviewed with us.

Although we believe that our consolidation of the Subsidiaries conforms with GAAP, there can be no assurance that the Staff will ultimately concur with our position. Such events could have a material impact on our future reported results.

Changes in laws or regulations governing our business could negatively affect the profitability of our operations.

Changes in the laws or regulations, or the interpretations of the laws and regulations, which govern business development companies, small business investment companies, RICs or non-depository commercial lenders could significantly affect our operations and our cost of doing business. We are subject to federal, state and local laws and regulations and are subject to judicial and administrative decisions that affect our operations, including

30

Table of Contents

our loan originations, maximum interest rates, fees and other charges, disclosures to portfolio companies, the terms of secured transactions, collection and foreclosure procedures, and other trade practices. If these laws, regulations or decisions change, or if we expand our business into jurisdictions that have adopted more stringent requirements than those in which we currently conduct business, then we may have to incur significant expenses in order to comply or we may have to restrict our operations. In addition, if we do not comply with applicable laws, regulations and decisions, then we may lose licenses needed for the conduct of our business and be subject to civil fines and criminal penalties, any of which could have a material adverse effect upon our business results of operations or financial condition.

Risks Related to Our Investments

Our investments are concentrated in a limited number of technology-related companies, which subjects us to the risk of significant loss if any of these companies default on their obligations under any of their debt securities that we hold, or if any of the technology-related industry sectors experience a downturn.

We have invested and intend to continue investing in a limited number of technology-related companies. A consequence of this limited number of investments is that the aggregate returns we realize may be significantly adversely affected if a small number of investments perform poorly or if we need to write down the value of any one investment. Beyond the asset diversification requirements to which we will be subject as a RIC, we do not have fixed guidelines for diversification or limitations on the size of our investments in any one portfolio company and our investments could be concentrated in relatively few issuers. In addition, we have invested in and intend to continue investing, under normal circumstances, at least 80% of the value of our total assets (including the amount of any borrowings for investment purposes) in technology-related and life-science companies. As a result, a downturn in technology-related and life-science industry sectors could materially adversely affect us.

Our investments may be concentrated in emerging-growth or expansion-stage portfolio companies, which may have limited operating histories and financial resources.

We expect that our portfolio will continue to consist primarily of investments in emerging-growth and expansion-stage privately-owned businesses, which may have relatively limited operating histories. Compared to larger established or publicly-owned firms, these companies may be particularly vulnerable to economic downturns, may have more limited access to capital and higher funding costs, may have a weaker financial position and may need more capital to expand or compete. These businesses also may experience substantial variations in operating results. They may face intense competition, including from companies with greater financial, technical and marketing resources. Furthermore, some of these companies do business in regulated industries and could be affected by changes in government regulation. Accordingly, these factors could impair their cash flow or result in other events, such as bankruptcy, which could limit their ability to repay their obligations to us, and may adversely affect the return on, or the recovery of, our investment in these companies. We cannot assure you that any of our investments in our portfolio companies will be successful. Our portfolio companies compete with larger, established companies with greater access to, and resources for, further development in these new technologies. We may lose our entire investment in any or all of our portfolio companies.

Our investment strategy focuses on technology-related and life-science companies, which are subject to many risks, including volatility, intense competition, shortened product life cycles and periodic downturns, and you could lose all or part of your investment.

We have invested and will continue investing primarily in technology-related and life-science companies, many of which may have narrow product lines and small market shares, which tend to render them more vulnerable to competitors’ actions and market conditions, as well as to general economic downturns. The revenues, income (or losses), and valuations of technology-related and life-science companies can and often do fluctuate suddenly and dramatically. In addition, technology- related markets are generally characterized by abrupt business cycles and intense competition. Beginning in mid-2000, there was substantial excess production

31

Table of Contents

capacity and a significant slowdown in many technology-related industries. This overcapacity, together with a cyclical economic downturn, resulted in substantial decreases in the market capitalization of many technology- related and life-science companies. While such valuations have recovered to some extent, such decreases in market capitalization may occur again, and any future decreases in technology-related and life-science company valuations may be substantial and may not be temporary in nature. Therefore, our portfolio companies may face considerably more risk of loss than do companies in other industry sectors.

Because of rapid technological change, the average selling prices of products and some services provided by technology-related and life-science companies have historically decreased over their productive lives. As a result, the average selling prices of products and services offered by technology-related and life-science companies may decrease over time, which could adversely affect their operating results, their ability to meet obligations under their debt securities and the value of their equity securities. This could, in turn, materially adversely affect our business, financial condition and results of operations.

We have invested in and may continue investing in technology-related and life-science companies that do not have venture capital or private equity firms as equity investors, and these companies may entail a higher risk of loss than do companies with institutional equity investors, which could increase the risk of loss of your investment.

Our portfolio companies will often require substantial additional equity financing to satisfy their continuing working capital and other cash requirements and, in most instances, to service the interest and principal payments on our investment. Portfolio companies that do not have venture capital or private equity investors may be unable to raise any additional capital to satisfy their obligations or to raise sufficient additional capital to reach the next stage of development. Portfolio companies that do not have venture capital or private equity investors may be less financially sophisticated and may not have access to independent members to serve on their boards, which means that they may be less successful than portfolio companies sponsored by venture capital or private equity firms. Accordingly, financing these types of companies may entail a higher risk of loss than would financing companies that are sponsored by venture capital or private equity firms.

Economic recessions or downturns could impair the ability of our portfolio companies to repay loans, which, in turn, could increase our non-performing assets, decrease the value of our portfolio, reduce our volume of new loans and harm our operating results, which might have an adverse effect on our results of operations.

Many of our portfolio companies may be susceptible to economic slowdowns or recessions and may be unable to repay our loans during such periods. Therefore, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease during such periods. Adverse economic conditions also may decrease the value of collateral securing some of our loans and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us.

A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of the portfolio company’s loans and foreclosure on its secured assets, which could trigger cross-defaults under other agreements and jeopardize the portfolio company’s ability to meet its obligations under the debt securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company. In addition, if a portfolio company goes bankrupt, even though we may have structured our investment as senior debt or secured debt, depending on the facts and circumstances, including the extent to which we actually provided significant “managerial assistance,” if any, to that portfolio company, a bankruptcy court might re-characterize our debt holding and subordinate all or a portion of our claim to that of other creditors. These events could harm our financial condition and operating results.

32

Table of Contents

We do not control our portfolio companies. These portfolio companies may face intense competition, including competition from companies with greater financial resources, more extensive research and development, manufacturing, marketing and service capabilities and greater number of qualified and experienced managerial and technical personnel. They may need additional financing which they are unable to secure and which we are unable or unwilling to provide, or they may be subject to adverse developments unrelated to the technologies they acquire.

The inability of our portfolio companies to commercialize their technologies or create or develop commercially viable products or businesses would have a negative impact on our investment returns.

The possibility that our portfolio companies will not be able to commercialize their technology, products or business concepts presents significant risks to the value of our investment. Additionally, although some of our portfolio companies may already have a commercially successful product or product line when we invest, technology-related and life-science products and services often have a more limited market- or life -span than have products in other industries. Thus, the ultimate success of these companies often depends on their ability to continually innovate, or raise additional capital, in increasingly competitive markets. Their inability to do so could affect our investment return. In addition, the intellectual property held by our portfolio companies often represents a substantial portion of the collateral, if any, securing our investments. We cannot assure you that any of our portfolio companies will successfully acquire or develop any new technologies, or that the intellectual property the companies currently hold will remain viable. Even if our portfolio companies are able to develop commercially viable products, the market for new products and services is highly competitive and rapidly changing. Neither our portfolio companies nor we have any control over the pace of technology development. Commercial success is difficult to predict, and the marketing efforts of our portfolio companies may not be successful.

An investment strategy focused primarily on privately-held companies presents certain challenges, including the lack of available information about these companies, a dependence on the talents and efforts of only a few key portfolio company personnel and a greater vulnerability to economic downturns.

We invest primarily in privately-held companies. Generally, very little public information exists about these companies, and we are required to rely on the ability of our management team to obtain adequate information to evaluate the potential returns from investing in these companies. If we are unable to uncover all material information about these companies, then we may not make a fully informed investment decision, and we may not receive the expected return on our investment or lose some or all of the money invested in these companies. Also, privately-held companies frequently have less diverse product lines and a smaller market presence than do larger competitors. Privately-held companies are, thus, generally more vulnerable to economic downturns and may experience more substantial variations in operating results than do larger competitors. These factors could affect our investment returns.

In addition, our success depends, in large part, upon the abilities of the key management personnel of our portfolio companies, who are responsible for the day-to-day operations of our portfolio companies. Competition for qualified personnel is intense at any stage of a company’s development, and high turnover of personnel is common in technology-related companies. The loss of one or more key managers can hinder or delay a company’s implementation of its business plan and harm its financial condition. Our portfolio companies may not be able to attract and retain qualified managers and personnel. Any inability to do so may negatively impact our investment returns.

If our portfolio companies are unable to protect their intellectual property rights, then our business and prospects could be harmed. If our portfolio companies are required to devote significant resources to protecting their intellectual property rights, then the value of our investment could be reduced.

Our future success and competitive position depend in part upon the ability of our portfolio companies to obtain and maintain proprietary technology used in their products and services, which will often represent a significant portion of the collateral, if any, securing our investment. The portfolio companies will rely, in part, on

patent, trade secret and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and disputes as to ownership of intellectual property may arise. Portfolio companies may, from time to time, be required to institute litigation in order to enforce their patents, copyrights or other intellectual property rights, to protect their trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a portfolio company is found to infringe upon or misappropriate a third party’s patent or other proprietary rights, that portfolio company could be required to pay damages to such third party, alter its own products or processes, obtain a license from the third party and/or cease activities utilizing such proprietary rights, including making or selling products utilizing such proprietary rights. Any of the foregoing events could negatively affect both the portfolio company’s ability to service our debt investment and the value of any related debt and equity securities that we own, as well as any collateral securing our investment.

We may not be able to realize our entire investment on equipment-based loans in the case of default.

We may from time-to-time provide loans that will be collateralized only by equipment of the portfolio company. If the portfolio company defaults on the loan we would take possession of the underlying equipment to satisfy the outstanding debt. The residual value of the equipment at the time we would take possession may not be sufficient to satisfy the outstanding debt and we could experience a loss on the disposition of the equipment.

Some of our portfolio companies may need additional capital, which may not be readily available.

Our portfolio companies will often require substantial additional equity financing to satisfy their continuing working capital and other requirements, and in most instances to service the interest and principal payments on our investment. Each round of venture financing is typically intended to provide a company with only enough capital to reach the next stage of development. We cannot predict the circumstances or market conditions under which our portfolio companies will seek additional capital. It is possible that one or more of our portfolio companies will not be able to raise additional financing or may be able to do so only at a price or on terms unfavorable to us, either of which would negatively impact our investment returns. Some of these companies may be unable to obtain sufficient financing from private investors, public capital markets or traditional lenders. Accordingly, financing these types of companies may entail a higher risk of loss than would financing companies that are able to utilize traditional credit sources.

We may be unable or decide not to make additional cash investments in our portfolio companies which could result in our losing our initial investment if the portfolio company fails.

We may have to make additional cash investments in our portfolio companies to protect our overall investment value in the particular company. We retain the discretion to make any additional investments as our management determines. The failure to make such additional investments may jeopardize the continued viability of a portfolio company, and our initial (and subsequent) investments. Moreover, additional investments may limit the number of companies in which we can make initial investments. In determining whether to make an additional investment our management will exercise its business judgment and apply criteria similar to those used when making the initial investment. We cannot assure you that we will have sufficient funds to make any necessary additional investments, which could adversely affect our success and result in the loss of a substantial portion or all of our investment in a portfolio company.

If our investments do not meet our performance expectations, you may not receive distributions.

We intend to make distributions on a quarterly basis to our stockholders. We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. In addition, due to the asset coverage test applicable to us as a business development company, we may be limited in our ability to make distributions. See “Regulation.” Also, restrictions and provisions in any future credit facilities may limit our ability to make distributions. As a RIC, if we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including failure to obtain, or possible loss of, the federal income tax benefits allowable to RICs. See “Certain United States Federal Income Tax Considerations—Taxation as a Regulated Investment Company.” We cannot assure you that you will receive distributions at a particular level or at all.

Table of Contents

Any unrealized depreciation that we experience on our loan portfolio may be an indication of future realized losses, which could reduce our income available for distribution.

As a business development company, we are required to carry our investments at market value or, if no market value is ascertainable, at the fair value as determined in good faith by our Board of Directors in accordance with procedures approved by our Board of Directors. Decreases in the market values or fair values of our investments will be recorded as unrealized depreciation. Any unrealized depreciation in our loan portfolio could be an indication of a portfolio company’s inability to meet its repayment obligations to us with respect to the affected loans. This could result in realized losses in the future and ultimately in reductions of our income available for distribution in future periods.

The lack of liquidity in our investments may adversely affect our business and, if we need to sell any of our investments, we may not be able to do so at a favorable price. As a result, we may suffer losses.

We generally invest in debt securities with terms of up to seven years and hold such investments until maturity, and we do not expect that our related holdings of equity securities will provide us with liquidity opportunities in the near-term. We invest and expect to continue investing in companies whose securities have no established trading market and whose securities are and will be subject to legal and other restrictions on resale or whose securities are and will be less liquid than are publicly-traded securities. The illiquidity of these investments may make it difficult for us to sell these investments when desired. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we had previously recorded these investments. As a result, we do not expect to achieve liquidity in our investments in the near-term. However, to maintain our qualification as a business development company and as a RIC, we may have to dispose of investments if we do not satisfy one or more of the applicable criteria under the respective regulatory frameworks. Our investments are usually subject to contractual or legal restrictions on resale, or are otherwise illiquid, because there is usually no established trading market for such investments. The illiquidity of most of our investments may make it difficult for us to dispose of the investments at a favorable price and, as a result, we may suffer losses.

If the assets securing the loans that we make decrease in value, then we may lack sufficient collateral to cover losses.

We believe that our portfolio companies generally will be able to repay our loans from their available capital, from future capital-raising transactions, or from cash flow from operations. However, to attempt to mitigate credit risks, we will typically take a security interest in the available assets of these portfolio companies, including the equity interests of their subsidiaries and, in some cases, the equity interests of our portfolio companies held by their stockholders. In many cases, our loans will include a period of interest-only payments. There is a risk that the collateral securing our loans may decrease in value over time, may be difficult to sell in a timely manner, may be difficult to appraise and may fluctuate in value based upon the success of the business and market conditions, including as a result of the inability of a portfolio company to raise additional capital. In some circumstances, our lien could be subordinated to claims of other creditors. Additionally, deterioration in a portfolio company’s financial condition and prospects, including its inability to raise additional capital, may be accompanied by deterioration in the value of the collateral for the loan. Moreover, in the case of some of our structured mezzanine debt, we may not have a first lien position on the collateral. Consequently, the fact that a loan is secured does not guarantee that we will receive principal and interest payments according to the loan’s terms, or that we will be able to collect on the loan should we be forced to enforce our remedies. In addition, because we invest in technology-related companies, a substantial portion of the assets securing our investment may be in the form of intellectual property, if any, inventory and equipment and, to a lesser extent, cash and accounts receivable. Intellectual property, if any, that is securing our loan could lose value if, among other things, the company’s rights to the intellectual property are challenged or if the company’s license to the intellectual property is revoked or expires. Inventory may not be adequate to secure our loan if our valuation of the inventory at the time that we made the loan was not accurate or if there is a reduction in the demand for the inventory.

35

Table of Contents

Similarly, any equipment securing our loan may not provide us with the anticipated security if there are changes in technology or advances in new equipment that render the particular equipment obsolete or of limited value, or if the company fails to adequately maintain or repair the equipment. Any one or more of the preceding factors could materially impair our ability to recover principal in a foreclosure.

Our portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies.

We invest primarily in debt securities issued by our portfolio companies. In some cases, portfolio companies will be permitted to have other debt that ranks equally with, or senior to, the debt securities in which we invest. Such debt instruments may provide that the holders thereof are entitled to receive payment of interest or principal on or before the dates on which we are entitled to receive payments in respect of the debt securities in which we invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution in respect of our investment. After repaying such senior creditors, such portfolio company might not have any remaining assets to use for repaying its obligation to us. In the case of debt ranking equally with debt securities in which we invest, we would have to share on a pari passu basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy. In addition, we would not be in a position to control any portfolio company by investing in its debt securities. As a result, we are subject to the risk that a portfolio company in which we invest may make business decisions with which we disagree and the management of such companies, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not best serve our interests as debt investors.

Our equity investments are highly speculative, and we may not realize gains from these investments. If our equity investments do not generate gains, then the return on our invested capital will be lower than it would otherwise be, which could result in a decline in the value of shares of our common stock.

When we invest in debt securities, we generally expect to acquire warrants or other equity securities as well. Our goal is ultimately to dispose of these equity interests and realize gains upon disposition of such interests. Over time, the gains that we realize on these equity interests may offset, to some extent, losses that we experience on defaults under debt securities that we hold. However, the equity interests that we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses that we experience.

We do not control any of our portfolio companies and therefore our portfolio companies may make decisions with which we disagree.

We do not control any of our portfolio companies, even though we may have board observation rights and our debt agreements may contain certain restrictive covenants. As a result, we are subject to the risk that a portfolio company in which we invest may make business decisions with which we disagree and the management of such company, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors.

Prepayments of our debt investments by our portfolio companies could adversely impact our results of operations and reduce our return on equity.

We are subject to the risk that the investments we make in our portfolio companies may be repaid prior to maturity. When this occurs, we will generally reinvest these proceeds in temporary investments, pending their future investment in new portfolio companies. These temporary investments will typically have substantially lower yields than the debt being prepaid and we could experience significant delays in reinvesting these amounts.

36

Table of Contents

Any future investment in a new portfolio company may also be at lower yields than the debt that was repaid. As a result, our results of operations could be materially adversely affected if one or more of our portfolio companies elects to prepay amounts owed to us. Additionally, prepayments could negatively impact our return on equity, which could result in a decline in the market price of our common stock.

We may not realize gains from our equity investments.

When we invest in debt securities, we generally expect to acquire warrants or other equity securities as well. However, the equity interests we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we experience.

Risks Related to Our Common Stock

Our common stock price may be volatile and may decrease substantially.

The trading price of our common stock following an offering may fluctuate substantially. The price of the common stock that will prevail in the market after an offering may be higher or lower than the price you paid and the liquidity of our common stock may be limited, in each case depending on many factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include, but are not limited to, the following:

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Due to the potential volatility of our stock price, we may be the target of securities litigation in the future. Securities litigation could result in substantial costs and could divert management’s attention and resources from our business.

37

Table of Contents

Investing in shares of our common stock may involve an above average degree of risk.

The investments we make in accordance with our investment objective may result in a higher amount of risk, volatility or loss of principal than alternative investment options. Our investments in portfolio companies may be highly speculative and aggressive, and therefore, an investment in our common stock may not be suitable for investors with lower risk tolerance.

We cannot assure you that the market price of our common stock will not decline.

We cannot predict the price at which our common stock will trade. Shares of closed-end investment companies have in the past frequently traded at discounts to their net asset values and our stock may also be discounted in the market. This characteristic of closed-end investment companies is separate and distinct from the risk that our net asset value per share may decline. We cannot predict whether shares of our common stock will trade above, at or below our net asset value. In addition, if our common stock trades below its net asset value, we will generally not be able to issue additional shares of our common stock at its market price without first obtaining the approval for such issuance from our stockholders and our independent directors.

Provisions of the Maryland General Corporation Law, and of our charter and bylaws, could deter takeover attempts and have an adverse impact on the price of our common stock.

The Maryland General Corporation Law and our charter and bylaws contain provisions that may have the effect of discouraging, delaying, or making difficult a change in control of our company or the removal of our incumbent directors. We will be covered by the Business Combination Act of the Maryland General Corporation Law to the extent that such statute is not superseded by applicable requirements of the 1940 Act. However, our Board of Directors has adopted a resolution exempting from the Business Combination Act any business combination between us and any person to the extent that such business combination receives the prior approval of our board, including a majority of our directors who are not interested persons as defined in the 1940 Act. Our Board of Directors has already adopted a resolution exempting from the Business Combination Act any business combination between us and certain investment funds managed by JMP Asset Management, LLC and certain investment funds managed by Farallon Capital Management, L.L.C., and we have agreed with such investment funds that we will not alter or repeal such board resolution prior to the date that is two years after such investment funds cease to own at least 10% of our outstanding common stock in a manner that would make the Business Combination Act applicable to acquisitions of our stock by such investment funds without the written consent of such investment funds. In addition, our bylaws contain a provision exempting from the Control Share Acquisition Act any and all acquisitions by any person of shares of our stock. We have agreed with certain investment funds managed by JMP Asset Management, LLC and certain investment funds managed by Farallon Capital Management, L.L.C. that we will not repeal or amend such provision of our bylaws in a manner that would make the Control Share Acquisition Act applicable to acquisitions of our stock by such investment funds without the written consent of such investment funds prior to the date that is two years after such investment funds cease to own at least 10% of our outstanding common stock. If the applicable board resolution is repealed following such period of time or if our board does not otherwise approve a business combination, the Business Combination Act and the Control Share Acquisition Act (if we amend our bylaws to be subject to that Act) may discourage others from trying to acquire control of us and increase the difficulty of consummating any offer.

Under our charter, our Board of Directors is divided into three classes serving staggered terms, which will make it more difficult for a hostile bidder to acquire control of us. In addition, our Board of Directors may, without stockholder action, authorize the issuance of shares of stock in one or more classes or series, including preferred stock. Subject to compliance with the 1940 Act, our Board of Directors may, without stockholder action, amend our charter to increase the number of shares of stock of any class or series that we have authority to issue. The existence of these provisions, among others, may have a negative impact on the price of our common stock and may discourage third party bids for ownership of our company. These provisions may prevent any premiums being offered to you for shares of our common stock.

asset value or at premiums that are unsustainable over the long term are separate and distinct from the risk that our net asset value will decrease. At times, our shares of common stock have traded at a premium to net asset value and at times our shares of common stock have traded at a discount to the net assets attributable to those shares.

SALES OF UNREGISTERED SECURITIES

During the three months ended December 31, 2006, we issued a total of 38,632 shares of common stock under our dividend reinvestment plan pursuant to an exemption from the registration requirements of the Securities Act of 1933. The aggregate offering price for the shares of common stock sold under the dividend reinvestment plan was approximately $512,000.

During the three months ended December 31, 2006, our Directors elected to take part of their compensation in the form of common stock in lieu of cash. We issued a total of 12,084 shares of common stock to the Directors with an aggregate price for the shares of common stock of approximately $155,000.

ISSUER PURCHASES OF EQUITY SECURITIES

We did not repurchase any shares of our common stock during the three months ended December 31, 2006.

DIVIDEND POLICY

As a RIC, we intend to distribute quarterly dividends to our stockholders. In order to avoid certain excise taxes imposed on RICs, we currently intend to distribute during each calendar year an amount at least equal to the sum of (1) 98% of our ordinary income for the calendar year, (2) 98% of our capital gains in excess of capital losses for the one year period ending on October 31 of the calendar year, and (3) any ordinary income and net capital gains for the preceding year that were not distributed during such year. We will not be subject to excise taxes on amounts on which we are required to pay corporate income tax (such as retained net capital gains). In order to obtain the tax benefits applicable to RICs, we will be required to distribute to our stockholders with respect to each taxable year at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses. We currently intend to retain for investment realized net long-term capital gains in excess of realized net short-term capital losses. We generally intend to make deemed distributions to our stockholders of any retained net capital gains. If this happens, you will be treated as if you received an actual distribution of the capital gains we retain and then reinvested the net after-tax proceeds in our common stock. You also may be eligible to claim a tax credit (or, in certain circumstances, a tax refund) equal to your allocable share of the tax we paid on the capital gains deemed distributed to you. Please refer to “Certain United States Federal Income Tax Considerations” for further information regarding the consequences of our retention of net capital gains. We may, in the future, make actual distributions to our stockholders of some or all realized net long-term capital gains in excess of realized net short-term capital losses. We can offer no assurance that we will achieve results that will permit the payment of any cash distributions and, if we issue senior securities, we will be prohibited from making distributions if doing so causes us to fail to maintain the asset coverage ratios stipulated by the 1940 Act or if distributions are limited by the terms of any of our borrowings. See “Regulation.”

We maintain an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a dividend, cash dividends will be automatically reinvested in additional shares of our common stock unless the stockholder specifically “opts out” of the dividend reinvestment plan and chooses to receive cash dividends. See “Dividend Reinvestment Plan.”

Our ability to make distributions will be limited by the asset coverage requirements under the 1940 Act.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements and related notes and other financial information appearing elsewhere in this report. In addition to historical information, the following discussion and other parts of this report contain forward-looking information that involves risks and uncertainties. Our actual results could differ materially from those anticipated by such forward-looking information due to the factors discussed under “Risk Factors,” “Forward-Looking Statements” appearing elsewhere herein.

Overview

We are a specialty finance company that provides debt and equity growth capital to technology-related companies at all stages of development. We primarily finance privately-held companies backed by leading venture capital and private equity firms and also may finance certain publicly-traded companies. Our principal office is located in the Silicon Valley and we have additional offices in the Boston, Boulder, Chicago and Columbus areas. Our goal is to be the leading structured mezzanine capital provider of choice for venture capital and private equity backed technology-related companies requiring sophisticated and customized financing solutions. We invest primarily in structured mezzanine debt and, to a lesser extent, in senior debt and equity investments. We use the term “structured mezzanine debt investment” to refer to any debt investment, such as a senior or subordinated secured loan, that is coupled with an equity component, including warrants, options or rights to purchase common or preferred stock. Our structured mezzanine debt investments will typically be secured by some or all of the assets of the portfolio company.

We are an internally managed, non-diversified closed-end investment company that has elected to be regulated as a business development company under the 1940 Act. As a business development company, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in “qualifying assets,” including securities of private U.S. companies, cash, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less.

From incorporation through December 31, 2005, we were taxed as a corporation under Subchapter C of the Internal Revenue Code (the Code). We are treated for federal income tax purposes as a RIC under Subchapter M of the Code as of January 1, 2006. To qualify for the benefits allowable to a RIC, we must, among other things, meet certain source-of-income and asset diversification and income distribution requirements. Pursuant to this election, we generally will not have to pay corporate-level taxes on any income that we distribute to our stockholders. However, such an election and qualification to be treated as a RIC requires that we comply with certain requirements contained in Subchapter M of the Code. For example, a RIC must meet certain requirements, including source-of-income, asset diversification and income distribution requirements. The income source requirement mandates that we receive 90% or more of our income from qualified earnings, typically referred to as “good income.” Qualified earnings may exclude such income as management fees received in connection with our SBIC or other potential outside managed funds and certain other fees.

Our portfolio is comprised of, and we anticipate that our portfolio will continue to be comprised of, investments in technology-related companies at various stages of their development. Consistent with regulatory requirements, we invest primarily in United States based companies and to a lesser extent in foreign companies. To date, our emphasis has been primarily on private companies following or in connection with their first institutional round of equity financing, which we refer to as emerging-growth companies, and private companies in later rounds of financing, which we refer to as expansion-stage companies. In 2007, we expect to increase our investment activity in established companies, comprised of private companies in one of their final rounds of equity financing prior to a liquidity event or select publicly-traded companies that lack access to public capital or are sensitive to equity ownership dilution.

Asset Management

We may engage in the asset management business by providing investment advisory services to funds that may be formed in the future. We may, from time to time, serve as the investment manager of such funds and may receive management and other fees for such services. Such funds may have overlapping investment objectives and may invest in asset classes similar to those targeted by us.

We have adopted an investment conflict policy to address any potential conflicts arising out of our role as an asset manager. Pursuant to the policy, the investment committee will also consider the investment criteria and objectives (including but not limited to, the stage of the borrower’s development, the length of the term of the loan, the type of collateral to secure the loan, and the purpose for which the proceeds of the loan will be used by the borrower) in order to make a fair determination as to which investment vehicle would be appropriate to make the investment.

With respect to equity investments in which the opportunity does not arise pursuant to a pre-existing contractual right granted to a particular investment vehicle, the investment committee shall determine in its reasonable judgment which investment vehicle is best suited to make the investment, provided that the investment committee may determine that allocating the opportunity between investment vehicles is reasonable. Notwithstanding this policy, we may nevertheless face conflicts in the allocation of investment opportunities. As a result, it is possible that we may not be given the opportunity to participate in certain investments made by investment funds managed by us.

Portfolio and Investment Activity

The total value of our investment portfolio was $283.2 million at December 31, 2006, as compared to $176.7 million at December 31, 2005. During the year ended December 31, 2006, we made debt commitments to 32 portfolio companies totaling $239.5 million and funded $193.0 million to 35 companies. We also made equity investments in five portfolio companies totaling $3.0 million during the year ended December 31, 2006, bringing total equity investments at fair value to approximately $8.1 million at December 31, 2006. The fair value of our warrant portfolio at December 31, 2006 and 2005, was $8.4 million and $5.2 million respectively. At December 31, 2006, we had unfunded contractual commitments of $55.5 million to 16 portfolio companies.

During the year ended December 31, 2006, we received normal principal repayments of $45.7 million, a total of eight companies made early repayments totaling $41.9 million, and we received pay downs of $3.7 million on one working line of credit. Total portfolio investment activity (exclusive of unearned income) as of and for the year ended December 31, 2006 was as follows:

The following table shows the fair value of our portfolio of investments by asset class as of December 31, 2006 and December 31, 2005 (excluding unearned income):

A summary of the company’s investment portfolio at value by geographic location is as follows:

Our portfolio companies are primarily small and medium sized companies in the biopharmaceutical, communications and networking, consumer and business products, electronics and computers, medical device, semiconductor and software industry sectors. These sectors are characterized by high margins, high growth rates, consolidation and product and market extension opportunities. Value is often vested in intangible assets and intellectual property.

The largest companies vary from year to year as new loans are recorded and loans pay off. Loan revenue, consisting of interest, fees, and recognition of gains on equity interests, can fluctuate dramatically when a loan is paid off or a related equity interest is sold. Revenue recognition in any given year can be highly concentrated among several portfolio companies. For years ended December 31, 2006 and 2005, our ten largest portfolio companies represented approximately 43.4% and approximately 58.7% of the total fair value of our investments. We had four investments that represent 5% or more of the fair value of its investments at December 31, 2006. At December 31, 2006, we had eleven equity investments which represented 100% of the total fair value of its equity investments and each represents 5% or more of the total fair value of such investments.

The following table shows the fair value of our portfolio by industry sector at December 31, 2006 and December 31, 2005 (excluding unearned income):

We use an investment grading system, which grades each debt investment on a scale of 1 to 5, to characterize and monitor our expected level of returns on the debt investments in our portfolio with 1 being the highest quality. See “Business—Investment Process—Loan and Compliance Administration.” The following table shows the distribution of our outstanding debt investments on the 1 to 5 investment grading scale at fair value as of December 31, 2006 and December 31, 2005:

As of December 31, 2006, our investments had a weighted average investment grading of 2.14 as compared to 2.05 at December 31, 2005. Our policy is to reduce the grading on our portfolio companies as they approach the point in time when they will require additional equity capital. Additionally, we may downgrade our portfolio companies if they are not meeting our financing criteria and their respective business plans. Various companies in our portfolio will require additional funding in the near term or have not met their business plans and have therefore been downgraded until the funding is complete or their operations improve. At December 31, 2006, eight portfolio companies have been graded at 3 and three portfolio companies have been graded 4 as compared to four and one portfolio companies, respectively, at December 31, 2005.

At December 31, 2006, the weighted average yield to maturity of our loan obligations was approximately 12.64%, down slightly compared to 12.87% at December 31, 2005, attributed to expansion to both early stage companies and asset based financing offered to more mature companies seeking revolver type financing solutions. Yields to maturity are computed using interest rates as of December 31, 2006 and December 31, 2005 and include amortization of loan facility fees, commitment fees and market premiums or discounts over the expected life of the debt investments, weighted by their respective costs when averaged and are based on the assumption that all contractual loan commitments have been fully funded.

Table of Contents

We generate revenue in the form of interest income, primarily from our investments in debt securities, and commitment and facility fees. Fees generated in connection with our debt investments are recognized over the life of the loan or, in some cases, recognized as earned. In addition, we generate revenue in the form of capital gains, if any, on warrants or other equity-related securities that we acquire from our portfolio companies. Our investments generally range from $1.0 million to $25.0 million, with an average initial principal balance of between $3.0 million and $7.0 million. Our debt investments have a term of between two and seven years and typically bear interest at a rate ranging from 8.0% to 14.0% (based on current interest rate conditions). In addition to the cash yields received on our loans, in some instances, our loans may also include any of the following: end-of-term payments, exit fees, balloon payment fees, prepayment fees, and diligence fees, which may be required to be included in income prior to receipt. In some cases, we collateralize our investments by obtaining security interests in our portfolio companies’ assets, which may include their intellectual property. In other cases, we may obtain a negative pledge covering a company’s intellectual property. Interest on debt securities is generally payable monthly, with amortization of principal typically occurring over the term of the security for emerging-growth and expansion-stage companies. In addition, certain loans may include an interest-only period ranging from three to twelve months. In limited instances in which we choose to defer amortization of the loan for a period of time from the date of the initial investment, the principal amount of the debt securities and any accrued but unpaid interest become due at the maturity date. Our mezzanine debt investments also generally have equity enhancement features, typically in the form of warrants or other equity-related securities designed to provide us with an opportunity for capital appreciation.

Results of Operations

Comparison of periods ended December 31, 2006 and 2005

Operating Income

Interest income totaled approximately $26.3 million and $9.8 million for 2006 and 2005, respectively. In 2006 and 2005, interest income included approximately $713,000 and $351,000 of income from accrued exit fees. Income from commitment and facility fees totaled approximately $3.2 million and $875,000 for 2006 and 2005, respectively. The increase in both interest and fee income was directly related to increases in origination activity as net investments at fair value grew by $106.5 million during 2006. At December 31, 2006 and 2005, we had approximately $3.4 million and $2.7 million of deferred income related to commitment and facility fees.

Operating Expenses

Operating expenses totaled approximately $18.4 million and $9.1 million during 2006 and 2005, respectively. Operating expenses for 2006 and 2005 included interest expense, loan fees and unused commitment fees under our Bridge Loan Credit Facility and the Citigroup Facility of approximately $6.6 million and $2.9 million, respectively. The increase in interest expense was due to a higher average debt balance of $70.7 million in 2006 as compared to $20.3 million in 2005. Employee compensation and benefits were approximately $5.8 million and $3.7 million during 2006 and 2005, respectively. The increase in employee compensation and benefits is due to increased number of employees from 19 to 26 and bonuses of approximately $2.2 million accrued in 2006. General and administrative expenses increased to $5.4 million in 2006 from $2.3 million in 2005 primarily due to increased Board of Directors costs, legal expenses, professional service costs related to our status as a public company and the creation of our SBIC subsidiaries as well as increased expenses associated with operating a business development company. In addition, we incurred approximately $618,000 of stock- based compensation expense in 2006 as compared to $252,000 in 2005. The increase in stock-based compensation expense was due to the additional stock option grants made in 2006. We anticipate that operating expenses will increase over the next twelve months as we continue to incur higher interest expense on higher average outstanding debt balances, increase the number of our employees to support our growth and incur additional expenses related to being a public company, including expenses related to continued compliance requirements under the Sarbanes-Oxley Act.

Net Investment Income (Loss) Before Income Tax Expense and Investment Gains and Losses

Net investment income before income tax expense for the year ended December 31, 2006 totaled $11.1 million as compared with a net investment income before income tax expense in 2005 of approximately $1.5 million. This change is made up of the items described above.

Net Investment Gains

In 2006, we generated realized gains totaling approximately $3.3 million from the sale of common stock of one communications and networking company, one internet consumer and business services company and two biopharmaceutical companies. We recognized realized losses in 2006 of approximately $4.9 million on the disposition of loans to two portfolio companies. We recognized a realized gain of approximately $482,000 during the year ended December 31, 2005 from the sale of common stock of one biopharmaceutical portfolio company. During 2006, we reversed approximately $162,000 of net unrealized gains to realized gains.

For the year ended December 31, 2006, net unrealized investment appreciation totaled approximately $2.5 million. The net unrealized appreciation and depreciation of investments is based on portfolio asset valuations determined in good faith by our Board of Directors, based on the recommendations of the Valuation Committee. For the year ended December 31, 2006, we recognized approximately $4.9 million of gross unrealized appreciation on 11 of our portfolio companies and approximately $1.6 million of gross unrealized depreciation on 41 of our portfolio companies. As of December 31, 2006, the net unrealized investment gains recognized by the company were reduced by approximately $377,000 for a warrant participation agreement with Citigroup. For a more detailed discussion, see “Borrowings.”

Income Taxes

Through December 31, 2005 we were taxed under Subchapter C of the Code and recorded a tax expense of $255,000 for 2005. We will elect to be treated as a RIC under Subchapter M of the Code with the filing of our 2006 federal income tax return which election will be effective as of January 1, 2006. Provided we continue to qualify as a RIC, our income generally will not be subject to federal income or excise tax to the extent we make the requisite distributions to stockholders. We have distributed and currently intend to distribute sufficient dividends to eliminate our investment company taxable income for 2006. As such, no provision for Federal or state income taxes related to operations in 2006 was required.

At December 31, 2005, the Company had a deferred tax asset of approximately $1,454,000 which was adjusted through operations during the first quarter of 2006. Upon the determination that Hercules would qualify as a regulated investment company, any remaining deferred tax asset was reversed. The Company elected to recognize all of its net built-in gains at the time of the conversion to a RIC and paid tax on the built-in gain with the filing of its 2005 tax return. In making this election, the portfolio was marked to market at the time of the RIC election and the Company paid approximately $294,000 in Federal and State tax on the resulting taxable gain. In addition, upon completion of the 2005 tax returns, we recorded an additional tax benefit of approximately $345,000.

To qualify as a RIC we were required by December 31, 2006 to distribute our earnings and profits while we were taxable as a C corporation. During 2006, we distributed $1.20 per share to our shareholders of which approximately $0.09 was deemed to be a distribution of these accumulated earnings and profits, $0.97 was deemed to be a distribution of 2006 income and $0.14 was a return of capital. The distribution of our income and our accumulated earnings and profits is considered ordinary income to our shareholders in 2006.

Net Increase in Net Assets Resulting from Operations and Earnings Per Share

For the year ended December 31, 2006 net income totaled approximately $11.4 million compared to net income of approximately $2.1 million for the period ended December 31, 2005. These changes are made up of the items previously described.

Basic net income per share was $0.85 and fully diluted net income per share was $0.84 per share for the year ended December 31, 2006 compared to basic and diluted net income per share of $0.30 per share for the period ended December 31, 2005. The net income per share for 2006 was affected by an increase in the weighted average shares outstanding of approximately 6.4 million shares and 6.5 million shares on a basic and diluted basis, respectively, in 2006 as compared to 2005.

Comparison of periods ended December 31, 2005 and 2004

Operating Income

Interest income totaled approximately $9.8 million and $214,000 for 2005 and 2004, respectively. In 2005, interest income included approximately $351,000 of revenue from accrued exit fees. Income from commitment and facility fees totaled approximately $875,000 and $0 for 2005 and 2004, respectively. The increases are the result of origination activity and yield from investments. At December 31, 2005, we had approximately $2.7 million of deferred revenue related to commitment and facility fees. We expect to generate additional interest income and loan commitment fees as we continue to originate additional investments.

Operating Expenses

Operating expenses totaled approximately $9.1 million and $2.3 million during 2005 and 2004, respectively. Operating expenses for 2005 included interest expense, loan fees and unused commitment fees under our Bridge Loan Credit Facility and the Citigroup Facility of approximately $2.9 million. There were no interest or loan fees in 2004. Employee compensation and benefits were approximately $3.7 million and $1.2 million during 2005 and 2004, respectively. The increase in employee compensation and benefits is due to increased number of employees from 11 to 19 and bonuses of approximately $1.3 million paid in 2005. General and administrative expenses increased to $2.3 million from $411,000 in 2004 primarily due to increased legal expenses, professional service costs related to our status as a public company and the creation of our SBIC subsidiaries as well as increased business development expenses. In addition, we incurred approximately $252,000 of stock-based compensation expense in 2005 as compared to $680,000 in 2004. The decrease in stock-based compensation expense was due to the immediate vesting of certain options granted in 2004. We anticipate that operating expenses will increase over the next twelve months as we continue to incur higher interest expense on higher average outstanding debt balances, increase the number of our employees to support our growth and incur additional expenses related to being a public company, including expenses related to the implementation of the requirements under the Sarbanes-Oxley Act.

Net Investment Income (Loss) Before Income Tax Expense and Investment Gains and Losses

Net investment income before income tax expense for the year ended December 31, 2005 totaled $1.5 million as compared with a net investment loss before income tax expense in 2004 of approximately $2.0 million. This change is made up of the items described above.

Net Investment Gains

For the period ended December 31, 2005, net unrealized investment appreciation totaled approximately $353,000. The net unrealized appreciation and depreciation of investments is based on portfolio asset valuations determined in good faith by our Board of Directors, based on the recommendations of the Valuation Committee of our Board of Directors. For the year ended December 31, 2005, we recognized approximately $4.1 million of

50

Table of Contents

gross unrealized appreciation on 14 of our portfolio investment companies and approximately $3.4 million of gross unrealized depreciation on 15 of our portfolio investment companies. Approximately $3.3 million of the unrealized depreciation was due to a reduction in the fair value of a loan to one portfolio company. The net unrealized investment gains recognized by the company were reduced by approximately $342,000 for a warrant participation agreement with Citigroup. We generated a net realized gain totaling approximately $482,000 from the sale of common stock of one biopharmaceutical portfolio company. We did not recognize any realized or unrealized gains or losses during the period ended December 31, 2004.

Income Taxes

We account for income taxes in accordance with the provisions of Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes, which requires that deferred income taxes be determined based upon the estimated future tax effects of differences between the financial statement and tax basis of assets and liabilities given the provisions of the enacted tax law. Valuation allowances are used to reduce deferred tax assets to the amount likely to be realized.

We will be treated as a RIC under Subchapter M of the Code for 2006. However, such an election and qualification to be treated as a RIC requires that we comply with certain requirements contained in Subchapter M of the Code. For example, a RIC must meet certain requirements, including source-of-income, asset diversification and income distribution requirements. The income source requirement mandates that we receive 90% or more of our income from qualified earnings, typically referred to as “good income.” Qualified earnings may exclude such income as management fees received in connection with our SBIC or other potential outside managed funds and certain other fees.

As such, we reported our financial position and results of operations under Subchapter C of the Code prior to 2006. As a C corporation, we accrued income tax expense on a quarterly basis until we were able to reasonably determine that we qualified as a RIC under requirements contained in Subchapter M of the Code. During 2006, we were able to reasonably determine that we could qualify as a RIC, and we accordingly reversed the income tax expense recorded during 2006 and adjusted through operations the $1.4 million deferred tax asset on our balance sheet at December 31, 2005. If we had been able to make the determination as of December 31, 2005, the impact of charging the deferred tax to operations would have reduced our NAV by approximately $0.15 per share.

Net Increase in Net Assets Resulting from Operations and Earnings Per Share

For the year ended December 31, 2005 net income totaled approximately $2.1 million compared to a net loss of approximately $2.0 million for the period ended December 31, 2004. These changes are made up of the items previously described.

Basic and diluted net income per share for the year ended December 31, 2005 was $0.30 as compared to a basic loss per share of $1.72 and diluted loss per share of $1.58 for the period ended December 31, 2004. The net income per share for 2005 was affected by an increase in the number of average shares outstanding in 2005 as compared to 2004 of approximately 5.9 million shares and 5.7 million shares on a basic and diluted basis, respectively.

Financial Condition, Liquidity and Capital Resources

At December 31, 2006, we had approximately $16.4 million in cash and cash equivalents and available borrowing capacity approximately $109.0 million under our Citigroup Facility, subject to existing terms and advance rates. We primarily invest cash on hand in interest bearing deposit accounts.

51

Table of Contents

For the year ended December 31, 2006, net cash used in operating activities totaled approximately $91.3 million as compared to $156.1 million in 2005. This decrease was due primarily due to proceeds of $87.5 million in principal repayments offset by $196.0 million used for investments in our portfolio companies as compared to $18.8 million in principal repayments offset by $177.8 million used for investments in 2005. Cash used in investing activities for the year ended December 31, 2006 totaled $1.5 million and was used for the purchase of capital equipment and other long-term assets. Net cash provided by financing activities totaled $93.7 million for the year ended December 31, 2006. In 2006, we received approximately $143.0 million in net proceeds from the sale of common stock, and made cash dividend payments of $14.2 million. 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.

As of December 31, 2006, net assets totaled $255.4 million, with a net asset value per share of $11.65. We intend to generate additional cash primarily from equity capital, future borrowings as well as cash flows from operations, including income earned from investments in our portfolio companies and, to a lesser extent, from the temporary investment of cash in U.S. government securities and other high-quality debt investments that mature in one year or less. Our primary use of funds will be investments in portfolio companies and cash distributions to holders of our common stock. After we have used our current capital resources, we expect to raise additional capital to support our future growth through future equity offerings, issuances of senior securities and/or future borrowings, to the extent permitted by the 1940 Act.

As required by the 1940 Act, our asset coverage must be at least 200% after each issuance of senior securities. Our asset coverage as of December 31, 2006 was approximately 723%.

We anticipate that we will continue to fund our investment activities through a combination of debt and additional equity capital over the next year. As of December 31, 2006, we had $41.0 million outstanding under the Citigroup Facility. Advances under the Facility bear interest at one-month LIBOR plus 165 basis points. As of December 31, 2006, based on $164.9 million of eligible loans in the collateral pool and existing advance rates, we have access to approximately $49.6 million of borrowing capacity available under our existing $150.0 million securitized credit facility from Citigroup. As additional new loans are funded and pledged as collateral, we will be able to increase our borrowing capacity under the Citigroup Facility beyond the current $49.6 million. In addition, Citigroup has an equity participation right of 10% of the realized gains on warrants collateralized under the Citigroup Facility. See Note 4 to the Consolidated Financial Statements for discussion of the participation right. We anticipate that portfolio fundings entered into in succeeding periods will allow us to utilize the full borrowing capacity of the Citigroup Facility.

On September 27, 2006, HTII received a license to operate as a Small Business Investment Company under the SBIC program and will be able to borrow funds from the SBA against eligible previously approved investments and additional contributions to regulatory capital. On January 30, 2007, HTII received notification that its initial application for leverage under its SBC license was approved allowing HTII to commence drawing up to $50.0 million of leverage under its first tranche of capital from the SBA. At December 31, 2006, we had a net investment of $10.4 million in HTII, and there are 4 outstanding investments in the amount of $11.1 million and we have not drawn any leverage. HTM is a wholly-owned subsidiary of the Company. The Company is the sole limited partner of HTII and HTM is the general partner.

During the fourth quarter of 2006, the Company raised approximately $104.1 million, net of estimated issuance costs, in a public offering of 8.2 million shares of common stock. The net proceeds from the sale of the shares in the offering were used to reduce credit borrowings, originate investments and for general corporate purposes. We believe these funding sources combined with cash on hand at December 31, 2006, cash provided from operations and financing activities will allow us to continue investing activities for 5 to 9 months.

Off Balance Sheet Arrangements

In the normal course of business, we are party to financial instruments with off-balance sheet risk. These consist primarily of unfunded commitments to extend credit, in the form of loans, to our portfolio companies. Unfunded commitments to provide funds to portfolio companies will not be reflected on our balance sheet. Our unfunded commitments may be significant from time to time. As of December 31, 2006, we had unfunded commitments of approximately $55.5 million. These commitments will be subject to the same underwriting and ongoing portfolio maintenance as are the on-balance sheet financial instruments that we hold. Since these commitments may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements.

Contractual Obligations

Future commitments under the credit facility and operating leases were as follows at December 31, 2006:

Borrowings

In April 2005, we entered into a bridge loan credit facility with Alcmene, a special purpose vehicle that is an affiliate of Farallon Capital Management, L.L.C., a shareholder of Hercules, which we refer to as the Bridge Loan Credit Facility. The Bridge Loan Credit Facility was a $25 million secured term loan, which provided for $25 million of available borrowings, all of which was drawn down on April 12, 2005.

On August 1, 2005, we amended our Bridge Loan Credit Facility with Alcmene Funding, LLC. The amended 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. At December 31, 2005, the interest rate under the Bridge Loan Credit Facility was 9.76% per year. We had $25.0 million of outstanding borrowings under the Bridge Loan Credit Facility at December 31, 2005. On March 6, 2006, we repaid $10 million of the Bridge Loan Credit Facility, and the interest rate was reduced to 10.86%. On May 10, 2006, we repaid the remaining $15.0 million of the Bridge Loan Credit Facility and paid a $500,000 loan fee due on maturity and all accrued and unpaid interest through the date of repayment. At December 31, 2006, the Bridge Loan Credit Facility was no longer outstanding.

On August 1, 2005, we, through Hercules Funding Trust I, our affiliated statutory trust, executed a $100 million securitized credit facility with Citigroup Global Markets Realty Corp., which we refer to as the Citigroup Facility. Our ability to make draws on the Citigroup Facility expires on July 31, 2007 as the result of an extension for an additional one year period under the existing terms and conditions. The Citigroup Facility is collateralized by loans and warrants from our portfolio companies, and includes an advance rate of approximately 55% of eligible loans. Interest on borrowings under the Citigroup Facility will be paid monthly and will be charged at one-month LIBOR plus a spread of 1.65%. We also paid a loan origination fee equal to

53

Table of Contents

0.25% of the Citigroup Facility and will be subject to an unused commitment fee of 0.25%. On March 6, 2006, the Company amended the Citigroup Facility with an agreement that increased the borrowing capacity under the facility to $125.0 million. On December 6, 2006, the Company amended the Citigroup Facility with an agreement that increased the borrowing capacity under the facility to $150.0 million. This additional increase expires on March 31, 2007.

The Citigroup Facility contains covenants that, among other things, require the Company to maintain a minimum net worth and to restrict the loans securing the Citigroup Facility to certain dollar amounts, to concentrations in certain geographic regions and industries, to certain loan grade classifications, to certain security interests, and to certain interest payment terms. Citigroup has an equity participation right through a warrant participation agreement on the pool of loans and warrants collateralized under the Citigroup Facility. Pursuant to the warrant participation agreement, the Company granted to Citigroup a 10% participation in all warrants held as collateral. As a result, Citigroup is entitled to 10% of the realized gains on the warrants until the realized gains paid to Citigroup pursuant to the agreement equals $3,750,000 (the “Maximum Participation Limit”). The obligations under the warrant participation agreement continue even after the Citigroup Facility is terminated until the Maximum Participation Limit has been reached. During the year ended December 31, 2006, the Company reduced its realized gain by approximately $221,000 for Citigroup’s participation in the gain on sale of an equity security and recorded an additional liability and reduced its unrealized gains by a net amount of approximately $35,000 for Citigroup’s participation. The value of their participation right on unrealized gains in the related equity investments since inception of the agreement was approximately $377,000 at December 31, 2006 and is included in accrued liabilities and reduces the unrealized gain recognized by the Company at December 31, 2006. Since inception of the agreement, the Company has paid Citigroup approximately $281,000 under the warrant participation agreement thereby reducing our realized gains.

We plan to aggregate pools of funded loans using the Citigroup Facility or other conduits that we may seek until a sufficiently large pool of funded loans is created which can then be securitized. We expect that any loans included in a securitization facility will be securitized on a non-recourse basis with respect to the credit losses on the loans. There can be no assurance that we will be able to complete this securitization strategy, or that it will be successful.

Dividends

The following table summarizes our dividends declared and paid on all shares, including restricted stock, to date:

During 2006, we distributed $1.20 per share to our shareholders of which approximately $0.09 was deemed to be a distribution of these accumulated earnings and profits, $0.97 was deemed to be a distribution of 2006 income and $0.14 was a return of capital.

On February 7, 2007, the Board of Directors announced a dividend of $0.30 per share to shareholders of record as of February 19, 2007 and payable on March 19, 2007.

Critical Accounting Policies

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and revenues and expenses during the period reported. On an ongoing basis, our management evaluates its estimates and assumptions, which are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates. Changes in our estimates and assumptions could materially impact our results of operations and financial condition.

Valuation of Portfolio Investments. The most significant estimate inherent in the preparation of our consolidated financial statements is the valuation of investments and the related amounts of unrealized appreciation and depreciation of investments recorded.

As a BDC, we invest primarily in illiquid securities, including debt and equity-related securities of private companies. Our investments are generally subject to some restrictions on resale and generally have no established trading market. Because of the type of investments that we make and the nature of our business, our valuation process requires an analysis of various factors. Our valuation methodology includes the examination of, among other things, the underlying investment performance, financial condition and market changing events that impact valuation.

At December 31, 2006, approximately 94% of our total assets represented investments in portfolio companies of which greater than 99% are valued at fair value by the Board of Directors. Value, as defined in Section 2(a) (41) of the 1940 Act, is (i) the market price for those securities for which a market quotation is readily available and (ii) for all other securities and assets, fair value is as determined in good faith by the Board of Directors. Since there is typically no readily available market value for the investments in our portfolio, we value substantially all of our investments at fair value as determined in good faith by our board pursuant to a valuation policy and a consistent valuation process. Due to the inherent uncertainty in determining the fair value of investments that do not have a readily available market value, the fair value of our investments determined in good faith by our board may differ significantly from the value that would have been used had a ready market existed for such investments, and the differences could be material.

There is no single standard for determining fair value in good faith. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment. Unlike banks, we are not permitted to provide a general reserve for anticipated loan losses. Instead, we must determine the fair value of each individual investment on a quarterly basis. We will record unrealized depreciation on investments when we believe that an investment has decreased in value, including where collection of a loan or realization of an equity security is doubtful. Conversely, where appropriate, we will record unrealized appreciation if we believe that the underlying portfolio company has appreciated in value and, therefore, that our investment has also appreciated in value.

With respect to private debt and equity securities, each investment is valued using industry valuation benchmarks, and, where appropriate, the value is assigned a discount reflecting the illiquid nature of the investment, and our minority, non-control position. When a qualifying external event such as a significant purchase transaction, public offering, or subsequent debt or equity sale occurs, the pricing indicated by the external event will be used to corroborate our private debt or equity valuation.

Interest Income. Interest income is recorded on the accrual basis to the extent that such amounts are expected to be collected. Original issue discounts are amortized into interest income as adjustments to the related loan’s yield over the contractual life of the loan. We stop accruing interest on our investments when it is determined that interest may no longer collectible.

Fee Income. Fee income includes loan commitment and facility fees for due diligence and structuring, as well as fees for transaction services and management services rendered by us to portfolio companies and other third parties. Loan and commitment fees are amortized into income over the contractual life of the loan. Management fees are generally recognized as income when the services are rendered.

Stock-Based Compensation. We have issued and may, from time to time, issue additional stock options to employees under our 2004 Equity Incentive Plan. We follow Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payments (“FAS 123R”), to account for stock options granted. Under FAS 123R, compensation expense associated with stock-based compensation is measured at the grant date based on the fair value of the award and is recognized.

Recent Developments

On January 3, 2007, in connection with our December 12, 2006 secondary offering, the underwriters exercised their over-allotment option and purchased an additional 840,000 shares of our common stock for additional gross proceeds to the company of approximately $11.0 million.

On January 30, 2007, HTII received notification that its initial application for leverage under its SBC license was approved allowing HTII to commence drawing up to $50.0 million of leverage under its first tranche of capital from the SBA.

During February 2007, Farallon Capital Management, L.L.C. and its related affiliates and Manuel Henriquez, the Company’s CEO, exercised warrants to purchase 132,480 and 75,075 shares of our common stock. The exercise price of the warrants was $10.57 per share resulting in net proceeds to us of approximately $2.2 million.

Recent Accounting Pronouncements

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxes (“FIN 48”). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing The Company’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. At this time, management is evaluating the implications of FIN 48 and its impact in the financial statements has not yet been determined.

In September 2006, the FASB issued Statement on Financial Accounting Standards No. 157, Fair Value Measurements (“FAS 157”). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. As of December 31, 2006, the Company does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements, however, additional disclosures will be required about the inputs used to develop the measurements of fair value and the effect of certain of the measurements reported in the statement of operations for a fiscal period.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including changes in interest rates. As of December 31, 2006, 36 loans in our portfolio were at fixed rates and 14 loans were at variable rates. Over time additional investments

may be at variable rates. We may, in the future, hedge against interest rate fluctuations by using standard hedging instruments such as futures, options, and forward contracts. While hedging activities may insulate us against changes in interest rates, they may also limit our ability to participate in the benefits of lower interest rates with respect to our borrowed funds and higher interest rates with respect to our portfolio of investments. Interest rates on our borrowings are based on LIBOR. At December 31, 2006, the borrowing rate under the Citigroup Facility was LIBOR plus 1.65%.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Hercules Technology Growth Capital, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. As defined by the SEC, internal control over financial reporting is a process designed under the supervision of the Company’s principal executive and principal financial and accounting officer, and effected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles.

The Company’s internal control over financial reporting is supported by written policies and procedures, that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of the Company’s management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management of the Company conducted an assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“the COSO Framework”). Based on this assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2006.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006, has been audited by Ernst & Young LLP, the registered public accounting firm that audited the Company’s financial statements, as stated in their report, a copy of which is included in this Annual Report on Form 10-K.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
