PROSPECTUS (Subject to Completion)

                        , 2009

13,000,000 Shares Common Stock

This prospectus relates to the offer, from time to time, of 13,000,000 shares of our common stock, par value $0.001 per share by us.

The shares of common stock may be offered at prices and terms to be described in one or more supplements to this prospectus. We may offer shares of common stock at a discount to net asset value per share in certain circumstances. On June 3, 2009, our common stockholders voted to allow us to issue common stock at a price below net asset value per share for a period of one year ending June 3, 2010. Sales of common stock at prices below net asset value per share dilute the interests of existing stockholders, have the effect of reducing our net asset value per share and may reduce our market price per share.

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 from seed and emerging growth to expansion and established stages of development, including select publicly listed companies and lower middle market companies. We primarily finance privately-held companies backed by leading venture capital and private equity firms and also may finance certain publicly-traded companies that lack access to public capital or are sensitive to equity ownership dilution as well as lower middle market companies. We source our investments through our principal office located in Silicon Valley, as well as additional offices in the Boston, Boulder and Chicago 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. We invest primarily in structured mezzanine debt and, to a lesser extent, in senior debt and equity.

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.

Our common stock is traded on the Nasdaq Global Select Market under the symbol “HTGC.” On September 24, 2009, the last reported sale price of a share of our common stock on the Nasdaq Global Select Market was $9.88. The net asset value per share of our common stock at June 30, 2009 (the last date prior to the date of this prospectus on which we determined net asset value) was $10.27.

An investment in our common stock may be speculative and involves risks including a heightened risk of total loss of investment. In addition, the companies in which we invest are subject to special risks. See “Risk Factors” beginning on page 13 to read about risks that you should consider before investing in our common stock, including the risk of leverage.

Please read this prospectus before investing and keep it for future reference. It contains important information about us that a prospective investor ought to know before investing in our common stock. We file annual, quarterly and current reports, proxy statements and other information about us with the Securities and Exchange Commission. The information is available free of charge by contacting us at 400 Hamilton Avenue, Suite 310, Palo Alto, California 94301 or by telephone calling collect at (650) 289-3060 or on our website at www.herculestech.com. The SEC also maintains a website at www.sec.gov that contains such information.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus may not be used to consummate sales of shares of common stock unless accompanied by a prospectus supplement.

FEES AND EXPENSES

The following table is intended to assist you in understanding the various costs and expenses that an investor in our common stock will bear directly or indirectly. However, we caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you” or “us” or that “we” will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in Hercules Technology Growth Capital.

Example

The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. These amounts are based upon our payment of annual operating expenses at the levels set forth in the table above and assume no additional leverage.

The example and the expenses in the tables above should not be considered a representation of our future expenses, and actual expenses may be greater or lesser than those shown. Moreover, while the example assumes, as required by the applicable rules of the SEC, a 5% annual return, our performance will vary and may result in a return greater or lesser than 5%. In addition, while the example assumes reinvestment of all dividends and distributions at net asset value, participants in our dividend reinvestment plan may receive shares valued at the market price in effect at that time. This price may be at, above or below net asset value. See “Dividend Reinvestment Plan” for additional information regarding our dividend reinvestment plan.

RISK FACTORS

Investing in our common stock may be speculative and involves a high degree of risk. Before you invest in shares of our common stock, you should be aware of various risks, including those described below. You should carefully consider these risks, together with all of the other information included in this prospectus, before you decide whether to make an investment in our common stock. The risks set forth below are not the only risks we face. If any of the following risks occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our net asset value and the trading price of our common stock could decline, and you may lose all or part of your investment.

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.

We are currently in a period of capital markets disruption and recession and we do not expect these conditions to improve in the near future.

The United States has been in a recession since late 2007. The U.S. capital markets continues to experience extreme volatility and disruption as evidenced by a continuing lack of liquidity in the debt capital markets, significant write-offs in the financial services sector, the repricing of credit risk in the broadly syndicated credit market and the failure of major financial institutions. Despite the actions of the United States federal government, these events continue to contribute to worsening general economic conditions that are materially and adversely impacting the broader financial and credit markets and reducing the availability of credit and equity capital for the markets as a whole and financial services firms in particular. In addition, consumer confidence continues to deteriorate and unemployment figures continued to increase during the first half of 2009. Disruptions in the capital markets have increased the spread between the yields realized on risk-free and higher risk securities, resulting in illiquidity in the debt capital markets. We believe these conditions may continue for a prolonged period of time or worsen in the future. A prolonged period of market illiquidity may cause us to reduce the value of loans we originate and/or fund, which could have an adverse effect on our business, financial condition, and results of operations. 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. These events could prevent us from increasing our investment originations and negatively impact our operating results.

Current market conditions have materially and adversely impacted debt and equity capital markets in the United States, which could result in a negative impact on our business and operations.

The debt and equity capital markets in the United States have been negatively impacted by significant write-offs in the financial services sector relating to subprime mortgages and the re-pricing of credit risk in the broadly syndicated market, among other things. These events, along with the deterioration of the housing market, the failure of major financial institutions and the resulting United States Federal government actions have led to worsening general economic conditions, which have materially and adversely impacted the broader financial and credit markets and have reduced the availability of debt and equity capital for the market as a whole and financial firms in particular. Commercial finance companies have previously utilized the securitization market to finance

13

Table of Contents

some investment activities and we had intended to use securitization financing. Due to the current dislocation of the securitization market, which we believe may continue for an extended period of time, access to this funding source has essentially been eliminated. We and other companies in the commercial finance sector may have to access alternative debt markets in order to grow. The debt capital that will be available may be at a higher cost, and terms and conditions may be less favorable which could negatively affect our financial performance and results. In addition, the prolonged continuation of further deterioration of current market conditions could adversely impact our business.

We have and may in the future choose to pay dividends in part in our own stock, in which case you may be required to pay tax in excess of the cash you receive.

We may in the future choose to pay dividends in part in our own common stock. Under a recently issued IRS revenue procedure, up to 90% of any such taxable dividend for 2009 could be payable in our stock. Consistent with this revenue procedure, we paid 90% of our quarterly 2009 dividend in shares of newly issued common stock. For periods for which the revenue procedure is not applicable, up to 80% of any taxable dividend could be payable in our own stock. Taxable stockholders receiving such dividends will be required to include the full amount of the dividend as ordinary income (or as long-term capital gain to the extent such distribution is properly designated as a capital gain dividend) to the extent of our current and accumulated earnings and profits for United States federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of our stockholders determine to sell shares of our stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of our stock.

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.

Table of Contents

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

A 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 ordinary income and realized net capital gains except for certain realized net long-term capital gains, which we may 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. 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. Given the current dislocation in the credit market, 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. If we are unable to incur additional debt, we may be required to raise additional equity at a time when it may be disadvantageous to do so. In addition, shares of closed-end investment companies have recently traded at discounts to their net asset values and our stock has been 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. If our common stock trades below its net asset value, we generally will 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. 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

15

Table of Contents

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 credit facility with Wells Fargo Foothill, Inc. 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 June 30, 2009, we had outstanding indebtedness of $0.4 million pursuant to our Wells Facility. In addition, as of June 30, 2009, we had approximately $130.6 million outstanding under our SBA debenture. Despite current market conditions, 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 Wells Facility. See “Management’s Discussion and Analysis of Financial Condition—Borrowings.”

As a business development company, generally we are not permitted to incur indebtedness unless immediately after such borrowing we have an asset coverage for total borrowings of at least 200% (i.e., the amount of debt may not exceed 50% of the value of our assets). In addition, we may not be permitted to declare any cash dividend or other distribution on our outstanding common shares, or purchase any such shares, unless, at the time of such declaration or purchase, we have asset coverage of at least 200% after deducting the amount of such dividend, distribution, or purchase price. 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. As of June 30, 2009 our asset coverage for senior indebtedness was significantly above the required asset coverage ratio, excluding SBA leverage.

Illustration. The following table illustrates the effect of leverage on returns from an investment in our common stock assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual returns may be higher or lower than those appearing in the table below.

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 June 30, 2009, portfolio investments, 99% of which are valued at fair value by the Board of Directors, were approximately 90% 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

16

Table of Contents

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.

In September 2006, the FASB issued Statement No. 157, Fair Value Measurements (“FAS 157”) which provides enhanced guidance for using fair value to measure assets and liabilities. FAS 157 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value but does not expand the use of fair value in any new circumstances. We adopted FAS 157 on January 1, 2008. For the year ended December 31, 2008, we recorded unrealized depreciation of approximately $21.4 million primarily due to the collapse in the current financial market and the resulting impact on our portfolio company valuations in accordance with FAS 157. The impact of FAS 157 on our consolidated financial statements for future periods cannot be determined at this time as it will be influenced by the estimates of fair value for those periods, the number and amount of investments we originate, acquire or exit and the effect of any additional guidance or any changes in the interpretation of this statement. See Note 1, “Summary of Significant Accounting Policies” from our Notes to the Consolidated Financial Statements included in this prospectus.

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 June 30, 2009 that are greater than 5% of net assets:

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. Under the 1940 Act, we are not permitted to incur indebtedness unless immediately after such borrowing we have an asset coverage for total borrowings of at least 200% (i.e., the amount of debt may not exceed 50% of the value of our assets). In addition, we may not be permitted to declare any cash dividend or other distribution on our outstanding common shares, or purchase any such shares, unless, at the time of such declaration or purchase, we have an asset coverage of at

17

Table of Contents

least 200% after deducting the amount of such dividend, distribution, or purchase price. 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. Moreover, we can offer no assurance that we will be able to issue and sell additional equity securities in the future, on favorable terms or at all.

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. The securitization market has effectively shut down with the recent financial market collapse and we cannot assure you that will be able to securitize our loans in the near future, or at all. 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 as a Business Development Company.”

We believe that most of the senior loans we make 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 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 or to pay a portion of our distributions using shares of newly issued common stock, consistent with Internal Revenue Service requirements, to satisfy such distribution requirements. If we are unable to obtain cash from other sources and are otherwise unable 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. See “Certain United States Federal Income Tax Considerations.”

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, or our business may not perform in a manner that will allow us to make a specified level of 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 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 both variable and 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 current initial investments in debt securities will be at floating rate with a floor. 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.

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 certain 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 certain 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 quarter ended June 30, 2009, we recorded an increase of the derivative liability related to this obligation and increased its unrealized appreciation by approximately $70,000 for Citigroup’s participation in unrealized gains in the warrant portfolio. The value of their participation right on unrealized appreciation in the related equity investments was approximately $548,000 at June 30, 2009 and is included in accrued liabilities.

20

Table of Contents

There can be no assurances that the unrealized appreciation of the warrants will not be higher or lower in future periods due to fluctuations in the value of the warrants, thereby increasing or reducing the effect on the cost of borrowing. Since inception of the agreement, we have paid Citigroup approximately $920,000 under the warrant participation agreement thereby reducing our realized gains by this amount.

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.

On August 25, 2008, we entered into the Wells Facility, a two-year revolving senior secured credit facility with an optional one-year extension with initial commitments of $50 million at closing. The Wells Facility has the capacity to increase to $300 million if additional lenders are added to the lending syndicate. See Note 3 to our consolidated financial statements. As of June 30, 2009, we had outstanding indebtedness of $0.4 million pursuant to our Wells Facility.

As of June 30, 2009, we have not added any additional lenders under the Wells Facility, although if the credit markets re-open we intend to do so in the future. Due to current credit conditions as a result of the recession, our cost of borrowing may increase with the addition of additional lenders under the Wells 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 the collateral pool. 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.

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

In addition to regulatory restrictions that restrict our ability to raise capital, the Wells Facility contains various covenants which, if not complied with, could accelerate repayment under the facility, thereby materially and adversely affecting our liquidity, financial condition, results of operations and ability to pay dividends.

The credit agreement governing the Wells Facility requires us to comply with certain financial and operational covenants. These covenants require us to, among other things, maintain certain financial ratios, including asset coverage, debt to equity and interest coverage, and a minimum tangible net worth of $250 million, contingent upon our total commitments under all lines of credit not exceeding $250 million. To the extent our total commitments exceed $250 million, the minimum tangible net worth covenant will increase on a pro rata basis commensurate with our net worth on a dollar for dollar basis. In addition, the tangible net worth covenant will increase by 90 cents on the dollar for every dollar of equity capital subsequently raised by us. As of June 30, 2009, we were in compliance with these covenants. However, our ability to continue to comply with these covenants in the future depends on many factors, some of which are beyond our control. For example, during the quarter ended June 30, 2009, as a result of depreciation of the fair value of our investments, our net

21

Table of Contents

worth declined to $364.2 million. Accordingly, there are no assurances that we will be able to comply with these covenants. Failure to comply with these covenants would result in a default which, if we were unable to obtain a waiver from the lenders, could accelerate repayment under the facilities and thereby have a material adverse impact on our liquidity, financial condition, results of operations and ability to pay dividends.

If we cannot obtain additional capital because of either regulatory or market price constraints, we could be forced to curtail or cease our new lending and investment activities, our net asset value could decrease and our level of distributions and liquidity could be affected adversely.

The current economic and capital markets conditions in the U.S. have severely reduced capital availability. Reflecting concern about the stability of the financial markets, many lenders and institutional investors have reduced or ceased providing funding to borrowers. This market turmoil and tightening of credit have led to increased market volatility and widespread reduction of business activity generally.

Our ability to secure additional financing and satisfy our financial obligations under indebtedness outstanding from time to time will depend upon our future operating performance, which is subject to the prevailing general economic and credit market conditions, including interest rate levels and the availability of credit generally, and financial, business and other factors, many of which are beyond our control. The prolonged continuation or worsening of current economic and capital market conditions could have a material adverse effect on our ability to secure financing on favorable terms, if at all.

As of June 30, 2009, we had outstanding indebtedness of $0.4 million pursuant to our Wells Facility and $130.6 million under SBA debenture and $56.1 million available borrowing capacity under these facilities.

As of June 30, 2009, we have been unable to secure additional lenders under our Wells Facility, and the amount of borrowing capacity available to us has been significantly reduced as a result of the termination of the Credit Facility. 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 and we may be limited in our ability to make new commitments or fundings to our portfolio companies.

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

Our wholly-owned subsidiary HT II is licensed to act as a SBIC and is regulated by the SBA. Under current SBA regulations, a licensed SBIC can provide capital to those entities that have a tangible net worth not exceeding $18.0 million and an average annual net income after Federal income taxes not exceeding $6.0 million for the two most recent fiscal years. In addition, a licensed SBIC must devote 20.0% of its investment activity to those entities that have a tangible net worth not exceeding $6.0 million and an average annual net income after Federal income taxes not exceeding $2.0 million for the two most recent fiscal years. The SBA 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 factors such as the number of employees and gross sales. The SBA regulations permit licensed SBICs to make long term loans to small businesses, invest in the equity securities of such businesses and provide them with consulting and advisory services. The SBA also places certain limitations on the financing terms of investments by SBICs in portfolio companies and prohibits SBICs from providing funds for certain purposes or to businesses in a few prohibited industries. Compliance with SBA requirements may cause HT II to forego attractive investment opportunities that are not permitted under SBA regulations.

Further, 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. The SBA prohibits, without prior SBA approval, a “change of control” of an SBIC or transfers that would result in any person (or a group of persons acting in concert) owning 10.0% or more of a class of capital stock of a licensed SBIC. If HT II fails to comply with

22

Table of Contents

applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit HT II’s use of debentures, declare outstanding debentures immediately due and payable, and/or limit HT II from making new investments. Such actions by the SBA would, in turn, negatively affect us because HT II is our wholly owned subsidiary.

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 elected to be treated as a RIC for federal income tax purposes with the filing of our federal corporate income tax return for 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.

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 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.

Results may fluctuate and may not be indicative of future performance.

Our operating results may fluctuate and, therefore, you should not rely on current or historical period results to be indicative of our performance in future reporting periods. Factors that could cause operating results to fluctuate include, but are not limited to, variations in the investment origination volume and fee income earned, changes in the accrual status of our debt investments, variations in timing of prepayments, variations in and the timing of the recognition of net realized gains or losses and changes in unrealized appreciation or depreciation, the level of our expenses, the degree to which we encounter competition in our markets, and general economic conditions.

Risks Related to Our Investments

Our investments are concentrated in certain industries and 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 companies. As of June 30, 2009, approximately 53.8% of the fair value of our portfolio was composed of investments in four industries: 16.3% was composed of investments in the communications and networking industry; 14.1% was composed of investments in the software industry; 12.5% was composed of investments in the drug discovery industry; and 10.9% was composed of investments in the information services industries. As a result, a downturn in technology-related industry sectors and particularly those in which we are heavily concentrated could materially adversely affect our financial condition.

Our investments may be concentrated in portfolio companies which may have limited operating histories and financial resources.

We expect that our portfolio will continue to consist of investments that may have relatively limited operating histories. These companies may be particularly vulnerable to economic downturns such as the current recession, 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, more 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 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 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 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 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 companies. While such valuations have recovered to some extent, such decreases in market capitalization may occur again, and any

24

Table of Contents

future decreases in technology-related 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 companies have historically decreased over their productive lives. As a result, the average selling prices of products and services offered by technology-related 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 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.

Price declines and illiquidity in the corporate debt markets could adversely affect the fair value of our portfolio investments, reducing our net asset value through increased net unrealized depreciation.

As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair market value as determined in good faith by or under the direction of our board of directors. As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company’s debt and equity), the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company’s securities to publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we use the pricing indicated by the external event to corroborate our valuation. Decreases in the market values or fair values of our investments are recorded as unrealized depreciation. The continuing unprecedented declines in prices and liquidity in the capital markets have resulted in some net unrealized depreciation in our portfolio. Although the markets have improved in recent months, conditions in the public and private debt and equity markets have not fully gone back to the normal periods. As a result, in the future, depending on market conditions, we could incur substantial realized losses and may suffer substantial unrealized depreciation in future periods, which could have a material adverse impact on our business, financial condition and results of operations.

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.

The United States markets and most other markets have entered into a period of recession. 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

25

Table of Contents

portfolio is likely to decrease during such periods. There were four loans on non-accrual status as of June 30, 2009 with a fair value of approximately $6.0 million. There were four loans on non-accrual status as of December 31, 2008 with a fair value of approximately $864,000. 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.

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.

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

As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by or under the direction of 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 investment portfolio could be an indication of a portfolio company’s inability to meet its repayment obligations to us with respect to the affected investments. This could result in realized losses in the future and ultimately in reductions of our income available for distribution in future periods.

A continuing lack of initial public offering opportunities may cause companies to stay in our portfolio longer, leading to lower returns, unrealized depreciation, or realized losses.

Beginning in about 2001, fewer venture capital-backed companies per annum have been able to complete initial public offerings (“IPOs”) than in the years of the previous decade. For the year ended December 31, 2008, only 7 venture capital-backed companies completed IPOs in the United States according to Dow Jones Venture Source. Moreover, in 2008, according to the Dow Jones Venture Source, the venture capital-backed companies that completed IPOs had a median age of about 8.3 years, which was older than the median age of venture capital-backed IPOs in any period since 2001-2002. Now that some of our companies are becoming more mature, a continuing lack of IPO opportunities for venture capital-backed companies could lead to companies staying longer in our portfolio as private entities still requiring funding. This situation may adversely affect the amount of available funding for early-stage companies in particular as, in general, venture-capital firms are being forced to provide additional financing to late-stage companies that cannot complete an IPO. In the best case, such stagnation would dampen returns, and in the worst case, could lead to unrealized depreciation and realized losses as some companies run short of cash and have to accept lower valuations in private fundings or are not able to access additional capital at all. A continuing lack of IPO opportunities for venture capital-backed companies is

26

Table of Contents

also causing some venture capital firms to change their strategies, leading some of them to reduce funding of their portfolio companies and making it more difficult for such companies to access capital and to fulfill their potential, which can result in unrealized depreciation and realized losses in such companies by other companies such as ourselves who are co-investors in such companies.

To the extent venture capital or private equity firms decrease or discontinue funding to their portfolio companies, our portfolio companies may not be able to meet their obligations under the debt securities that we hold.

Most of our portfolio companies rely heavily on future rounds of funding from venture capital or private equity firms in order to continue operating their businesses and repaying their obligations to us under the debt securities that we hold. Venture capital and private equity firms in turn rely on their limited partners to pay in capital over time in order to fund their ongoing and future investment activities.

To the extent that venture capital and private equity firms’ limited partners are unable to fulfill their ongoing funding obligations, the venture capital or private equity firms may be unable to continue financially supporting the ongoing operations of our portfolio companies. As a result, our portfolio companies may be unable to repay their obligations under the debt securities that we hold, which would harm our financial condition and results of operations.

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 debt with warrants, 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.

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.

The economic recession and future downturns or recessions could impair the value of the collateral for our loans to our portfolio companies and consequently increase the possibility of an adverse effect on our financial condition and results of operations.

Many of our portfolio companies are susceptible to the current economic recession 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 may also decrease the value of collateral securing some of our loans and the value of our equity investments.

In particular, intellectual property owned or controlled by our portfolio companies constitutes an important portion of the value of the collateral of our loans to our portfolio companies. Adverse economic conditions may decrease the demand for our portfolio companies’ intellectual property and consequently its value in the event of a bankruptcy or required sale through a foreclosure proceeding. As a result, our ability to fully recover the amounts owed to us under the terms of the loans may be impaired by such events.

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.

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.

We may suffer a loss if a portfolio company defaults on a loan and the underlying collateral is not sufficient.

In the event of a default by a portfolio company on a secured loan, we will only have recourse to the assets collateralizing the loan. If the underlying collateral value is less than the loan amount, we will suffer a loss. In addition, we sometimes make loans that are unsecured, which are subject to the risk that other lenders may be directly secured by the assets of the portfolio company. In the event of a default, those collateralized lenders would have priority over us with respect to the proceeds of a sale of the underlying assets. In cases described above, we may lack control over the underlying asset collateralizing our loan or the underlying assets of the portfolio company prior to a default, and as a result the value of the collateral may be reduced by acts or omissions by owners or managers of the assets.

In the event of bankruptcy of a portfolio company, we may not have full recourse to its assets in order to satisfy our loan, or our loan may be subject to equitable subordination. See “Our loans could be subject to equitable subordination by a court which would increase our risk of loss with respect to such loans” above. In addition, certain of our loans are subordinate to other debt of the portfolio company. If a portfolio company defaults on our loan or on debt senior to our loan, or in the event of a portfolio company bankruptcy, our loan

28

Table of Contents

will be satisfied only after the senior debt receives payment. Where debt senior to our loan exists, the presence of intercreditor arrangements may limit our ability to amend our loan documents, assign our loans, accept prepayments, exercise our remedies (through “standstill” periods) and control decisions made in bankruptcy proceedings relating to the portfolio company. Bankruptcy and portfolio company litigation can significantly increase collection losses and the time needed for us to acquire the underlying collateral in the event of a default, during which time the collateral may decline in value, causing us to suffer losses.

If the value of collateral underlying our loan declines or interest rates increase during the term of our loan, a portfolio company may not be able to obtain the necessary funds to repay our loan at maturity through refinancing. Decreasing collateral value and/or increasing interest rates may hinder a portfolio company’s ability to refinance our loan because the underlying collateral cannot satisfy the debt service coverage requirements necessary to obtain new financing. If a borrower is unable to repay our loan at maturity, we could suffer a loss which may adversely impact our financial performance.

The collateral securing a loan may not be sufficient to protect us from a partial or complete loss if we have not properly obtained or perfected a lien on such collateral or if the loan becomes non-performing, and we are required to foreclose.

While most of our loans are secured by collateral, there is no assurance that we have obtained or properly perfected our liens, or that the value of the collateral securing any particular loan will protect us from suffering a partial or complete loss if the loan becomes non-performing and we move to foreclose on the collateral.

Our loans could be subject to equitable subordination by a court which would increase our risk of loss with respect to such loans.

Courts may apply the doctrine of equitable subordination to subordinate the claim or lien of a lender against a borrower to claims or liens of other creditors of the borrower, when the lender or its affiliates is found to have engaged in unfair, inequitable or fraudulent conduct. The courts have also applied the doctrine of equitable subordination when a lender or its affiliates is found to have exerted inappropriate control over a client, including control resulting from the ownership of equity interests in a client. We have made direct equity investments or received warrants in connection with loans representing approximately 9.0% of the aggregate outstanding balance of our portfolio as of June 30, 2009. Payments on one or more of our loans, particularly a loan to a client in which we also hold an equity interest, may be subject to claims of equitable subordination. If we were deemed to have the ability to control or otherwise exercise influence over the business and affairs of one or more of our portfolio companies resulting in economic hardship to other creditors of that company, this control or influence may constitute grounds for equitable subordination and a court may treat one or more of our loans as if it were unsecured or common equity in the portfolio company. In that case, if the portfolio company were to liquidate, we would be entitled to repayment of our loan on a pro-rata basis with other unsecured debt or, if the effect of subordination was to place us at the level of common equity, then on an equal basis with other holders of the portfolio company’s common equity only after all of its obligations relating to its debt and preferred securities had been satisfied.

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 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

29

Table of Contents

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.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.

Our investment strategy contemplates that a portion of our investments may be in securities of foreign companies. Investing in foreign companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes, less liquid markets and less available information than is generally the case in the U.S., higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

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.

We may not have sufficient funds to make follow-on investments. Our decision not to make a follow-on investment may have a negative impact on a portfolio company in need of such an investment or may result in a missed opportunity for us.

After our initial investment in a portfolio company, we may be called upon from time to time to provide additional funds to such company or have the opportunity to increase our investment in a successful situation, for example, the exercise of a warrant to purchase common stock. There is no assurance that we will make, or will have sufficient funds to make, follow-on investments. Any decision we make not to make a follow-on investment or any inability on our part to make such an investment may have a negative impact on a portfolio company in need of such an investment or may result in a missed opportunity for us to increase our participation in a successful operation and may dilute our equity interest or otherwise reduce the expected yield on our investment.

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

31

Table of Contents

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.

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.

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 related 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.

For the first six months of 2009 and full year of 2008, we received early loan repayments and paydown of working capital loans of approximately $105.5 million and $120.1 million, respectively. 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. 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 elect 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.

Our financial results could be negatively affected if we are unable to recover our principal investment as a result of a negative pledge on the intellectual property of our portfolio companies.

In some cases, we collateralize our investments by obtaining a first priority security interest in a portfolio companies’ assets, which may include their intellectual property. In other cases, we may obtain a first priority security interest in a portion of a portfolio company’s assets and a negative pledge covering a company’s intellectual property and a first priority security interest in the proceeds from such intellectual property. In the case of a negative pledge, the portfolio company cannot encumber or pledge their intellectual property without our permission. In the event of a default on a loan, the intellectual property of the portfolio company will most likely be liquidated to provide proceeds to pay the creditors of the company. As a result, a negative pledge may affect our ability to fully recover our principal investment. In addition, there can be no assurance that our security interest in the proceeds of the intellectual property will be enforceable in a court of law or bankruptcy court.

33

Table of Contents

At June 30, 2009, approximately 71.8% of our portfolio company loans were secured by a first priority security in all of the assets of the portfolio company, 1.4% of our portfolio company loans were secured by a second priority security in all of the assets of the portfolio company and 26.8% portfolio company loans were prohibited from pledging or encumbering their intellectual property pursuant to negative pledges.

We may choose to waive or defer enforcement of covenants in the debt securities held in our portfolio, which may cause us to lose all or part of our investment in these companies.

We structure the debt investments in our portfolio companies to include business and financial covenants placing affirmative and negative obligations on the operation of the company’s business and its financial condition. However, from time to time we may elect to waive breaches of these covenants, including our right to payment, or waive or defer enforcement of remedies, such as acceleration of obligations or foreclosure on collateral, depending upon the financial condition and prospects of the particular portfolio company. These actions may reduce the likelihood of our receiving the full amount of future payments of interest or principal and be accompanied by a deterioration in the value of the underlying collateral as many of these companies may have limited financial resources, may be unable to meet future obligations and may go bankrupt. This could negatively impact our ability to pay dividends and cause the loss of all or part of your investment.

Risks Related to Our Common Stock

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.

Our common stock may trade below its net asset value per share, which limits our ability to raise additional equity capital.

If our common stock is trading below its net asset value per share, 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. Shares of business development companies, including shares of our common stock, have been trading at discounts to their net asset values. As of June 30, 2009, our net asset value per share was $10.27. The daily average closing price of our shares on the NASDAQ Global Select Market for the quarter ended June 30, 2009 was $7.36. If our common stock trades below net asset value, the higher cost of equity capital may result in it being unattractive to raise new equity, which may limit our ability to grow. The risk of trading below net asset value 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.

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. In addition, our bylaws contain a provision exempting from the Control Share Acquisition Act any and all

34

Table of Contents

acquisitions by any person of shares of our stock. The Business Combination Act (if our board should repeal the resolution) 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.

If we conduct an offering of our common stock at a price below net asset value, investors are likely to incur immediate dilution upon the closing of the offering.

At our Annual Meeting of Stockholders on June 3, 2009, stockholders approved a proposal authorizing us to sell up to 20% of our common stock at a price below the Company’s net asset value per share, subject to Board approval of the offering. If we were to issue shares at a price below net asset value, such sales would result in an immediate dilution to existing common stockholders, which would include a reduction in the net asset value per share as a result of the issuance. This dilution would also include a proportionately greater decrease in a stockholder’s interest in our earnings and assets and voting interest in us than the increase in our assets resulting from such issuance.

In addition, if we determined to conduct additional offerings in the future there may be even greater discounts if we determine to conduct such offerings at prices below net asset value. As a result, investors will experience further dilution and additional discounts to the price of our common stock.

Because the number of shares of common stock that could be so issued and the timing of any issuance is not currently known, the actual dilutive effect of an offering cannot be predicted. We did not sell any of our common stocks at a price below our net asset value during the six months ended June 30, 2009.

Current levels of market volatility are unprecedented. Our common stock price has been and continues to be volatile and may decrease substantially.

The capital and credit market have been experiencing extreme volatility and disruption for more than 12 months. Although the markets have improved in recent months, the volatility and disruption have reached unprecedented levels, and we have experienced greater than usual stock price volatility. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. If current levels of market volatility continue or worsen, there can be no assurance that we will not experience an adverse effect, which may be material, on our ability to access capital and on our business, financial condition and results of operations.

In addition, 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:

35

Table of Contents

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.

We may be unable to invest the net proceeds raised from an offering on acceptable terms, which would harm our financial condition and operating results.

Until we identify investments for our portfolio, we intend to invest the net proceeds from an offering in cash, cash equivalents, U.S. government securities or high-quality debt securities. We cannot assure you that we will be able to complete investments that meet our investment criteria or that any investment we complete using the proceeds from an offering will produce a sufficient return. Moreover, because we may not have identified all investments at the time of an offering, we will have broad authority to invest the net proceeds of an offering. We will not receive any proceeds from an offering by the selling holders.

FORWARD-LOOKING STATEMENTS; MARKET DATA

The matters discussed in this prospectus, as well as in future oral and written statements by management of Hercules Technology Growth Capital, that are forward-looking statements are based on current management expectations that involve substantial risks and uncertainties which could cause actual results to differ materially from the results expressed in, or implied by, these forward-looking statements. Forward-looking statements relate to future events or our future financial performance. We generally identify forward-looking statements by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar words. Important assumptions include our ability to originate new investments, achieve certain margins and levels of profitability, the availability of additional capital, and the ability to maintain certain debt to asset ratios. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus should not be regarded as a representation by us that our plans or objectives will be achieved. The forward-looking statements contained in this prospectus include statements as to:

For a discussion of factors that could cause our actual results to differ from forward-looking statements contained in this prospectus, please see the discussion under “Risk Factors.” You should not place undue reliance on these forward-looking statements. The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made.

This prospectus contains third-party estimates and data regarding valuations of venture capital-backed companies. This data was reported by Dow Jones VentureSource, an independent venture capital industry research company which we refer to as VentureSource. VentureSource is commonly relied upon as an information source in the venture capital industry. Although we have not independently verified any such data, we believe that the industry information contained in such releases and data tables and included in this prospectus is reliable.

We have compiled certain industry estimates presented in this prospectus from internally generated information and data. While we believe our estimates are reliable, they have not been verified by any independent sources. The estimates are based on a number of assumptions, including increasing investment in venture capital and private equity-backed companies. Actual results may differ from projections and estimates, and this market may not grow at the rates projected, or at all. If this market fails to grow at projected rates, our business and the market price of our common stock could be materially adversely affected.

USE OF PROCEEDS

We intend to use the net proceeds from selling shares of common stock for general corporate purposes, which include investing in debt and equity securities and other general corporate purposes. The supplement to this prospectus relating to an offering will more fully identify the use of proceeds from such offering.

We anticipate that substantially all of the net proceeds from any offering of our shares of common stock will be used as described above within twelve months, but in no event longer than two years. Pending such uses and investments, we will invest the net proceeds primarily in cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or less from the time of investment. Our ability to achieve our investment objective may be limited to the extent that the net proceeds of any offering, pending full investment, are held in lower yielding short-term instruments.

Our common stock is traded on the Nasdaq Global Select Market under the symbol “HTGC.”

The following table sets forth the range of high and low sales prices of our common stock as reported on the Nasdaq Global Select Market, the closing sales price as a percentage of net asset value and the dividends declared by us for each fiscal quarter. The stock quotations are interdealer quotations and do not include markups, markdowns or commissions.

The last reported price for our common stock on September 24, 2009 was $9.88 per share.

Shares of business development companies may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that our shares of common stock will trade at a discount from net 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. It is not possible to predict whether the shares offered hereby will trade at, above, or below net asset value.

Dividends

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

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. The determination of the tax attributes of our distributions is made annually as of the end of our fiscal year based upon its taxable income for the full year and distributions paid for the full year, therefore a determination made on a quarterly basis may not be representative of the actual tax attributes of our distributions for a full year. If the company had determined the attributes of its distributions year-to-date as of June 30, 2009, approximately $0.62 or 100% would be from ordinary income and earnings spilled over from 2008, however there can be no certainty to shareholders that this determination is representative of what the tax attributes of its 2009 distributions to shareholders will actually be. During 2008, we distributed $1.32 per share to our shareholders of which 100% was deemed to be a distribution of income and is considered ordinary income to our shareholders in 2008.

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.

Effective in 2009, our Board of Directors adopted a policy to distribute four quarterly distributions in an amount that approximates 90 to 95% of our taxable income. In addition, at the end of the year, we may also pay an additional special dividend, such that we may distribute approximately 98% of our annual taxable income in the year it was earned, instead of spilling over our excess taxable income.

On February 12, 2009, the Board of Directors announced a dividend of $0.32 per share to shareholders of record as of February 23, 2008. In accordance with the Internal Revenue Procedure released in January 2009, our Board of Directors determined to pay 90% of the dividend in newly issued shares of common stock and 10% of the dividend in cash. On March 30, 2009, we paid a cash dividend of approximately $1.1 million and issued approximately 1.9 million shares of common stock as stock dividend in satisfaction of the dividend declared on February 12, 2009. The market value per share of common stock used to compute the stock dividend (the “Dividend Share Value”) is the volume weighted average price per share of HTGC’s common stock for the three business day period of March 23, March 24 and March 25, 2009. We currently intend to retain for investment some or all of our net capital gains (that is, the excess of our realized net long-term capital gains over our realized net short-term capital losses) and 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. To the extent that we do not retain all of our net capital gains, we will make actual distributions to our stockholders of such gains.

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. For a more detailed discussion, see “Regulation.”

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” and “Forward-Looking Statements; Market Data” 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 from seed and emerging growth to expansion and established stages of development. We primarily finance privately-held companies backed by leading venture capital and private equity firms, and may also finance select publicly listed companies and lower middle market companies. Our principal office is located in the Silicon Valley and we have additional offices in Boston, Boulder and Chicago. Our goal is to be the leading structured debt financing provider of choice for venture capital and private equity backed technology-related companies requiring sophisticated and customized financing solutions. Our strategy is to evaluate and invest in a broad range of companies active in the technology and life science industries and to offer a full suite of growth capital products up and down the capital structure. We invest primarily in structured debt with warrants and, to a lesser extent, in senior debt and equity investments. We use the term “structured debt with warrants” 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 debt with warrants investments will typically be secured by all assets of the portfolio company or a portion thereof.

Our primary business objectives are to increase our assets from operations, net investment income and net asset value by investing in structured debt with warrants 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. 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 primarily in technology-related companies at various stages of development. Consistent with regulatory requirements, we invest primarily in United States based companies and to a lesser extent in foreign

companies. Since 2008, our investing emphasis has been primarily on private companies following or in connection with a subsequent institutional round of equity financing, which we refer to as expansion-stage companies and private companies in later rounds of financing and certain public companies, which we refer to as established-stage companies and lower middle market companies. We have also historically focused our investment activities in private companies following or in connection with the first institutional round of financing, which we refer to as emerging-growth companies. Early in 2008, we announced our “slow and steady” investment strategy and the shift in our investment focus to established-stage, or lower middle market companies. These changes were made to manage our credit performance, maintain adequate liquidity and manage our operating expenses in this extremely challenging and unprecedented credit environment.

The U.S. capital and credit markets have been experiencing extreme disruption since the summer of 2008, as evidenced by a lack of liquidity in the debt capital markets, significant write-offs in the financial services sector, the repricing of credit risk in the broadly syndicated credit market and the failure of many major financial institutions. These events have contributed to a continuing severe economic recession that is materially and adversely impacting the broader financial and credit markets and reducing the availability of credit and equity capital for the markets as a whole and financial services firms in particular, including us. Like many other companies, we have also begun engaging in activities to deleverage our balance sheet and strengthen cash resources available to us.

Portfolio and Investment Activity

The total value of our investment portfolio was $452.4 million at June 30, 2009 as compared to $581.3 million, $530.0 million and $283.2 million at the years ended December 31, 2008, 2007 and 2006. During the six-month period ended June 30, 2009 and the years ended December 31, 2008, 2007 and 2006, we made debt commitments totaling $134.8 million, $405.7 million, $480.5 million and $239.5 million, respectively, and funded approximately $68.2 million, $346.0 million, $355.5 million, and $193.0 million, respectively. Debt commitments for the six month period ended June 30, 2009 included commitments of approximately $7.0 million to one new portfolio company, $39.6 million in refinancing through our SBIC, renewals of approximately $27.5 million of working capital lines and restructurings of approximately $60.7 million. During the six-month period ended June 30, 2009, we made an equity investment of approximately $400,000 in one existing portfolio company. At June 30, 2009, we had unfunded contractual commitments of $25.0 million to 11 portfolio companies. Since these commitments may expire without being drawn, unfunded commitments do not necessarily represent future cash requirements. In addition, the Company had no non-binding term sheets outstanding. Non-binding outstanding term sheets are subject to completion of the Company’s due diligence and final approval process, as well as the negotiation of definitive documentation with the prospective portfolio companies. Not all non-binding term sheets are expected to close and do not necessarily represent future cash requirements.

The fair value of the loan portfolio at June 30, 2009 was approximately $411.7 million, compared to a fair value of approximately $540.1 million, $482.1 million and $266.7 million at the years ended December 31, 2008, 2007 and 2006. The fair value of the equity portfolio at June 30, 2009 was approximately $25.4 million. The fair value of the equity portfolio at the years ended December 31, 2008, 2007 and 2006 was approximately $23.4 million, $26.2 million and $8.1 million, respectively. The fair value of our warrant portfolio at June 30, 2009 was approximately $15.3 million. The fair value of the warrant portfolio at the years ended December 31, 2008, 2007 and 2006 was approximately $17.9 million, $21.6 million and $8.4 million, respectively.

We receive payments in our loan portfolio based on scheduled amortization of the outstanding balances. In addition, we receive repayments of some of our loans prior to their scheduled maturity date. The frequency or volume of these repayments may fluctuate significantly from period to period. During the six-month period ended June 30, 2009, we received normal principal amortization repayments of $62.0 million, and early repayments and working line of credit paydowns totaling $105.0 million. For the years ended December 31, 2008, 2007 and 2006, we received normal principal amortization payments of approximately $110.3 million,

$66.5 million and $45.7 million, respectively, and early repayments and working line of credit paydowns totaling approximately $105.5 million, $83.8 million and $41.9 million, respectively. Total portfolio investment activity (exclusive of unearned income) as of the six-month period ended June 30, 2009 and as of year ended December 31, 2008 is as follows:

The following table shows the fair value of our portfolio of investments by asset class (excluding unearned income) as of the six-month period ended June 30, 2009 and as of the year ended December 31, 2008:

A summary of our investment portfolio at value by geographic location as of the six-month period ended June 30, 2009 and as of the year ended December 31, 2008 is as follows:

Our portfolio companies are primarily privately held expansion and established-stage companies in the biopharmaceutical, communications and networking, consumer and business products, electronics and computers, energy, information services, internet consumer and business services, medical devices, 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.

At June 30, 2009, we had investments in two portfolio companies deemed to be Affiliates. Income derived from these investments was less than $500,000 since these investments became Affiliates. We recognized a realized loss of approximately $4.0 million during the six-month period ended June 30, 2009 in a portfolio company that was an affiliate prior to the disposal of the investment. No realized gains or losses related to Affiliates were recognized during the six-month period ended June 30, 2008 and as of years ended December 31, 2008, 2007 and 2006.

The following table shows the fair value of our portfolio by industry sector at June 30, 2009 and December 31, 2008 (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 risk on the debt investments in our portfolio with 1 being the highest quality. The following table shows the distribution of our outstanding debt investments on the 1 to 5 investment grading scale at fair value as of June 30, 2009 and December 31, 2008.

As of June 30, 2009, our investments had a weighted average investment grading of 2.70 as compared to 2.39, 2.20, and 2.14 at December 31, 2008, December 31, 2007 and December 31, 2006, respectively. We are shifting our focus to expansion and established-stage companies in order to maintain our portfolio credit quality

despite the current adverse financial markets. However, there is no guarantee that this strategy will be successful. Our policy is to lower 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 their funding is complete or their operations improve. At June 30, 2009, 16 portfolio companies were graded 3 and 6 portfolio companies were graded 4, as compared to 19 portfolio companies that were graded 3 and 5 portfolio companies that were graded 4 at December 31, 2008. At June 30, 2009 and December 31, 2008, there were 6 and 5 portfolio companies that were graded 5, respectively.

The effective yield on our debt investments at June 30, 2009, December 31, 2008, December 31, 2007 and December 31, 2006 was 16.1%, 13.5%, 12.8%, and 14.9%, respectively. The increase in the effective yield is primarily due to higher fee income attributed to loan amendments. The overall weighted average yield to maturity of our loan obligations was approximately 13.5% at June 30, 2009 as compared to 12.87%, 12.7% and 12.64% as of December 31, 2008, December 31, 2007 and December 31, 2006, respectively, attributed to higher interest rates on new loans and loans refinanced in the second quarter of 2009. The weighted average yield to maturity is computed using the interest rates in effect at the inception of each of the loans, and includes amortization of the 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 based on the assumption that all contractual loan commitments have been fully funded and held to maturity.

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. Our debt investments have a term of between two and seven years and typically bear interest at a rate ranging from Prime to 17% as of June 30, 2009. 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, PIK provisions, prepayment fees, and diligence fees, which may be required to be included in income prior to receipt. In most 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. At June 30, 2009, approximately 71.8% of portfolio company loans were secured by a first priority security in all of the assets of the portfolio company, 26.8% of portfolio company loans were prohibited from pledging or encumbering the portfolio company’s intellectual property and 1.4% of our loans are second lien facilities. Interest on debt securities is generally payable monthly, with amortization of principal typically occurring over the term of the security for emerging-growth, expansion-stage and established-stage companies. In addition, certain loans may include an interest-only period ranging from three to eighteen months for emerging-growth and expansion-stage companies and longer for established-stage companies. 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 investments in structured debt with warrants 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. As of June 30, 2009, we have received warrants in connection with the majority of our debt investments in each portfolio company. Our warrant coverage generally ranges from 3% to 20% of the principal amount invested in a portfolio company, with a strike price equal to the most recent equity financing round. As of June 30, 2009, we hold warrants in 88 portfolio companies, with a fair value of approximately $15.3 million included in the investment portfolio of $452.4 million. These warrant holdings would require us to invest approximately $52.5 million to exercise such warrants. However, these warrants may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our warrant interests.

Results of Operations

Comparison of the Six-Month Periods Ended June 30, 2009 and 2008

Operating Income

Interest income totaled approximately $33.8 million for the six-month periods ended June 30, 2009, compared with $30.3 million for the six-month periods ended June 30, 2008, respectively. Income from commitment, facility and loan related fees totaled approximately $6.1 million for the six-month periods ended June 30, 2009, compared with $4.3 million in the same periods ended June 30, 2008, respectively. In the six months ended June 30, 2009 and 2008, total investment income increased $5.3 million year over year, respectively, despite a decline of 9% in average investment assets over the same period, due to higher average yield on the debt portfolio, early debt repayment fees, restructuring charges and default interest on certain debt investments.

Operating Expenses

Operating expenses totaled approximately $16.6 million during the six months ended June 30, 2009, compared with $15.7 million for the six months ended June 30, 2008, respectively. Operating expenses for the six months ended June 30, 2009 included interest expense, loan fees and unused commitment fees of approximately $6.5 million, respectively, compared with $5.7 million for the six-month periods ended June 30, 2008. The 14% decrease in interest and loan fee expenses relates to a lower average outstanding debt balance of $135.8 million in the second quarter of 2009 as compared to $180.9 million in the second quarter of 2008 as well as a lower average cost of debt as the Citibank/Deutsche Bank credit facility was paid off on March 29, 2009. The higher cost of capital for the six months ended June 30, 2009 as compared to the same period of 2008 is primarily due to the Citibank/Deutsche Bank credit facility entering the amortization period during which borrowings under the facility was bearing interest at LIBOR + 650 Bps as compared to the prior year when the facility interest rate was at LIBOR + 120 Bps.

Employee compensation and benefits were relatively consistent at approximately $5.7 million during the six months ended June 30, 2009, compared with $5.7 million during the six-month periods ended June 30 2008, respectively. General and administrative expenses for the six month periods ended June 30, 2009 which include legal, consulting and accounting fees, insurance premiums, rent and various other expenses decreased $3.4 million, down from $3.4 million during the six months ended June 30, 2008. The decrease was primarily attributable to lower expense for legal, travel and entertainment, and recruiting offset by higher work-out and public company related expenses. In addition, we incurred approximately $989,000 of stock-based compensation expense in the six months of 2009 as compared $901,000 in the same periods of 2008. The increase was due to additional option and restricted stock grants made in 2009, which increased the basis of the total stock based compensation expenses during six month periods of 2009.

Net Investment Income Before Investment Gains and Losses

Net investment income per share was $0.69 for the first six months of 2009, compared to $0.58 per share in the same period of 2008. Net investment income before investment gains and losses for the six months ended June 30, 2009 totaled $23.4 million as compared to $19.0 million in the six-month periods of 2008. The changes are made up of the items described above under “Operating Income” and “Operating Expenses”.

Net Investment Realized Gains and Losses and Unrealized Appreciation and Depreciation

Realized gains or losses are measured by the difference between the net proceeds from the repayment or sale and the cost basis of the investment without regard to unrealized appreciation or depreciation previously recognized, and includes investments charged off during the period, net of recoveries. Net change in unrealized appreciation or depreciation primarily reflects the change in portfolio investment values during the reporting period, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized.

Table of Contents

For the six months ended June 30, 2009, we generated realized gains totaling approximately $1.5 million mainly from the sale of common stock of one biotech company, one drug delivery company and one drug discovery company. We recognized realized losses on loans, equity and warrants of approximately $6.9 million from the investment exit from one software company, one drug discovery company and one communication and networking company. For the six months ended June 30, 2008, we generated realized gain totaling approximately $5.5 million due to the sale of one biopharmaceutical company offset by $615,000 loss primarily from the sale of one semiconductors company. A summary of realized gains and losses and unrealized appreciation and depreciation for the three and six-month periods ended June 30, 2009 and 2008 is as follows:

During the six months ended June 30, 2009 and 2008, net unrealized depreciation totaled approximately $26.6 million and $4.4 million, respectively. The net unrealized appreciation and depreciation of our investments is based on fair value of each investment determined in good faith by our Board of Directors. This net unrealized depreciation was primarily comprised of decreases in the carrying value of our portfolio companies due to credit performance and market conditions. For the six-month period ended June 30, 2009 approximately $29.7 million of the net depreciation recognized was attributable to debt investments in those companies. The remaining depreciation was attributable to depreciation of approximately $1.1 million in warrants held in our portfolio companies offset by appreciation of approximately $4.2 million in our equity investments. As of June 30, 2009, the net unrealized depreciation recognized by the Company was increased by approximately $50,000 due to the warrant participation agreement with Citigroup. For a more detailed discussion of the warrant participation agreement, see the discussion set forth under Note 4 to the consolidated financial statements. The following table itemizes the change in net unrealized depreciation of investments for the six-month periods ended June 30, 2009 and 2008:
