PROSPECTUS (Subject to Completion)

October 5, 2012

$400,000,000

Common Stock

Preferred Stock

Warrants

Subscription Rights

Debt Securities

This prospectus relates to the offer, from time to time, in one or more offerings or series, up to $400,000,000 of shares of our common stock, par value $0.001 per share, preferred stock, par value $0.001 per share, warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, subscription rights or debt securities, which we refer to, collectively, as the “securities.” The preferred stock, debt securities, subscription rights and warrants offered hereby may be convertible or exchangeable into shares of our common stock. We may sell our securities through underwriters or dealers, “at-the-market” to or through a market maker into an existing trading market or otherwise directly to one or more purchasers, including existing stockholders in a rights offering, or through agents or through a combination of methods of sale. The identities of such underwriters, dealers, market makers or agents, as the case may be, will be described in one or more supplements to this prospectus. The securities may be offered at prices and on 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 May 30, 2012, 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 May 30, 2013. 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. In the event we offer common stock, the offering price per share will not be less than the net asset value per share of our common stock at the time we make the offering except (1) in connection with a rights offering to our existing stockholders, (2) with the consent of the holders of the majority of our voting securities and approval of our board of directors, or (3) under such circumstances as the Securities and Exchange Commission may permit. See “Risk Factors” for more information.

We are a specialty finance company that provides debt and equity growth capital to technology-related companies at various stages of development from seed and emerging growth to expansion and established stages of development, which include 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. We source our investments through our principal office located in Silicon Valley, as well as additional offices in Boston, MA, Boulder, CO and McLean, VA. Our goal is to be the leading structured debt financing provider of choice for entrepreneurial venture capital and private equity backed technology-related companies requiring sophisticated and customized financing solutions. We invest primarily in structured debt with warrants and, to a lesser extent, in senior debt and equity investments.

Our investment objective is to maximize our portfolio 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 New York Stock Exchange, or NYSE, under the symbol “HTGC.” On October 4, 2012, the last reported sale price of a share of our common stock on the NYSE, was $11.09. The net asset value per share of our common stock at June 30, 2012 (the last date prior to the date of this prospectus on which we determined net asset value) was $9.54.

An investment in our securities 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 16 to read about risks that you should consider before investing in our securities, 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 securities. 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.

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, Inc.

Table of Contents

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 securities may be speculative and involves a high degree of risk. Before you invest in our securities, 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 securities. 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 securities could decline, and you may lose all or part of your investment.

Risks Related to our Business 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.

The 1940 Act and the Code impose numerous constraints on the operations of BDCs and RICs. For example, under the 1940 Act, BDCs are required to invest at least 70% of their total assets primarily in securities of private or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and other high quality debt investments that mature in one year or less. Moreover, qualification for taxation as a RIC under subchapter M of the Code requires satisfaction of source-of-income and diversification requirements and our ability to avoid corporate level taxes on our income and gains depends on our satisfaction of distribution requirements. The failure to comply with these provisions in a timely manner could prevent us from qualifying as a BDC or RIC or could force us to pay unexpected taxes and penalties, which could be material. These constraints, among others, may hinder our ability to take advantage of attractive investment opportunities and to achieve our investment objective. Our experience operating under these constraints is limited to the period since our inception.

Our business is subject to increasingly complex corporate governance, public disclosure and accounting requirements that could adversely affect our business and financial results.

We are subject to changing rules and regulations of federal and state government as well as the stock exchange on which our common stock is listed. These entities, including the Public Company Accounting Oversight Board, the SEC and the NYSE, have issued a significant number of new and increasingly complex requirements and regulations over the course of the last several years and continue to develop additional regulations and requirements in response to laws enacted by Congress. On July 21, 2010, the Dodd-Frank Wall Street Reform and Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and executive compensation-related provisions in the Dodd-Frank Act that require the SEC to adopt additional rules and regulations in these areas such as “say on pay” and proxy access. Our efforts to comply with these requirements have resulted in, and are likely to continue to result in, an increase in expenses and a diversion of management’s time from other business activities.

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

Under applicable Treasury regulations and certain private rulings issued by the Internal Revenue Service, RICs are permitted to treat certain distributions payable in up to 80% in their stock, as taxable dividends that will satisfy their annual distribution obligations for federal income tax and excise tax purposes provided that shareholders have the opportunity to elect to receive the distribution in cash. 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

16

Table of Contents

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, then such sales may put downward pressure on the trading price of our stock. We previously determined to pay a portion of our first quarter 2009 dividend in shares of newly issued common stock, and we may in the future determine to distribute taxable dividends that are payable in part in our common stock.

We are dependent upon key management personnel for their time availability and 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. Furthermore, we do not have an employment agreement with Mr. Henriquez and our senior management is not restricted from creating new investment vehicles subject to compliance with applicable law. 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, our relationships become strained as a result of enforcing our rights with respect to non-performing portfolio companies in protecting our investments or we fail to develop new relationships with other firms or sources of investment opportunities, then we will not be able to grow our investment portfolio. In addition, persons with whom members of our management team have relationships are not obligated to provide us with investment opportunities and, therefore, there is no assurance that such relationships will lead to the origination of debt or other investments.

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

A 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

17

Table of Contents

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. 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. 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. In addition, our results of operations and financial condition could be adversely affected.

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

Lenders have fixed dollar claims on our assets that are superior to the claims of stockholders, and we have granted, and may in the future grant, lenders a security interest in our assets in connection with borrowings. In the case of a liquidation event, those lenders would receive proceeds before our stockholders. In addition, borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our securities. Leverage is generally considered a speculative investment technique. If the value of our assets increases, then leveraging would cause the net asset value attributable to our common stock to increase more than it otherwise would have had we not leveraged. Conversely, if the value of our assets decreases, leveraging would cause the net asset value attributable to our common stock to decline more than it otherwise would have had we not leveraged. Similarly, any increase in our revenue in excess of interest expense on our borrowed funds would cause our net income to increase more than it would without the leverage. Any decrease in our revenue would cause our net income to decline more than it would have had we not borrowed funds and could negatively affect our ability to make distributions on common stock. Our ability to service any debt that we incur will depend largely on our financial performance and will be subject to prevailing economic conditions and competitive pressures. We and, indirectly, our stockholders will bear the cost associated with our leverage activity. Our secured credit facilities with Wells Fargo Capital Finance LLC and RBC Capital Markets and Union Bank, N.A. and RBC Capital Markets, our Convertible Senior Notes, and our April 2019 Notes and September 2019 Notes contain 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, 2012, we did not have any outstanding borrowings under our credit facility with Union Bank and approximately $3.0 million outstanding under our credit facility with Wells Fargo. In addition, as of June 30,

18

Table of Contents

2012, we had approximately $225.0 million of indebtedness outstanding incurred by our SBIC subsidiaries, $75.0 million of Convertible Senior Notes payable, approximately $41.5 million of March 2019 Notes and approximately $83.4 million of September 2019 Notes. 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.

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, 2012 our asset coverage ratio under our regulatory requirements as a business development company was 654.3%, excluding our SBIC debentures as a result of our exemptive order from the SEC which allows us to exclude all SBA leverage from our asset coverage ratio. Total leverage when including our SBIC debentures was 246.2% at June 30, 2012.

Pending legislation may allow us to incur additional leverage.

As a business development company, under the 1940 Act 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). Recent legislation introduced in the U.S. House of Representatives, if passed, would modify this section of the 1940 Act and increase the amount of debt that business development companies may incur by modifying the percentage from 200% to 150%. As a result, we may be able to incur additional indebtedness in the future and therefore your risk of an investment in us may increase.

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

Under our borrowings and credit facilities, including the Union Bank Facility and the Wells Facility, current lenders have, and any future lender or lenders may 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. Our current credit facilities and borrowings also subject us to various financial and operating covenants, including, but not limited to, maintaining certain financial ratios and minimum tangible net worth amounts. Future credit facilities and borrowings will likely subject us to similar or additional covenants. In addition, we may grant a securities interest in our assets in connection with any such credit facilities and borrowings.

Our current credit facilities generally 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. In addition, such credit facilities require or are expected to require the repayment of all outstanding debt on the maturity

19

Table of Contents

which may disrupt our business and potentially the business of our portfolio companies that are financed through the facilities. An event of default under these facilities would likely result, among other things, in termination of the availability of further funds under the facilities and accelerated maturity dates for all amounts outstanding under the facilities, which would likely disrupt our business and, potentially, the business of the portfolio companies whose loans we finance through the facilities. This could reduce our revenues and, by delaying any cash payment allowed to us under our facilities 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 operation flexibility. If we are unable to obtain sufficient capital in the future, we may be forced to reduce or discontinue our operations, not be able to make new investments, or otherwise respond to changing business conditions or competitive pressures.

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, 2012, portfolio investments, which are valued at fair value by the Board of Directors, were approximately 90.1% of our total assets. We expect our investments to continue to consist primarily of securities issued by privately-held companies, the fair value of which is not readily determinable. In addition, we are not permitted to maintain a general reserve for anticipated loan losses. Instead, we are required by the 1940 Act to specifically value each investment and record an unrealized gain or loss for any asset that we believe has increased or decreased in value.

There is no single standard for determining fair value in good faith. We value these securities at fair value as determined in good faith by our Board of Directors, based on the recommendations of our Valuation Committee. The Valuation Committee uses its best judgment in arriving at the fair value of these securities. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment while applying a valuation process for the types of investments we make which includes, but is not limited to, deriving a hypothetical exit price. However, the Board of Directors retains ultimate authority as to the appropriate valuation of each investment. Because such valuations are inherently uncertain and may be based on estimates, our determinations of fair value may differ materially from the values that would be assessed if a ready market for these securities existed. We adjust quarterly the valuation of our portfolio to reflect the Board of Directors’ determination of the fair value of each investment in our portfolio. Any changes in fair value are recorded in our statement of operations as net change in unrealized appreciation or depreciation. Our net asset value could be adversely affected if our determinations regarding the fair value of our investments were materially higher than the values that we ultimately realize upon the disposal of such securities.

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

Our total investment in companies may be significant individually or in the aggregate. As a result, if a significant investment in one or more companies fails to perform as expected, our financial results could be more negatively affected and the magnitude of the loss could be more significant than if we had made smaller investments in more companies. The following table shows the fair value of the totals of investments held in portfolio companies at June 30, 2012 that represent greater than 5% of net assets:

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

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, changes in our portfolio composition, the degree to which we encounter competition in our markets, market volatility in our publicly traded securities and the securities of our portfolio companies, 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.

Our investments may be 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 U.S. and foreign economic downturns such as the current recession and European financial crisis 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 equity ownership in a portfolio company may represent a control investment. Our ability to exit an investment in a timely manner because we are in a control position or have access to inside information in the portfolio company could result in a realized loss on the investment.

If we obtain a control investment in a portfolio company our ability to divest ourselves from a debt or equity investment could be restricted due to illiquidity in a private stock, limited trading volume on a public company’s

21

Table of Contents

stock, inside information on a company’s performance, insider blackout periods, or other factors that could prohibit us from disposing of the investment as we would if it were not a control investment. Additionally, we may choose not to take certain actions to protect a debt investment in a control investment portfolio company. As a result, we could experience a decrease in the value of our portfolio company holdings and potentially incur a realized loss on the investment.

Regulations governing our operations as a business development company may 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 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.”

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.

A failure on our part to maintain our qualification as a business development company would significantly reduce our operating flexibility.

If we fail to continuously qualify as a business development company, we might be subject to regulation as a registered closed-end investment company under the 1940 Act, which would significantly decrease our operating flexibility. In addition, failure to comply with the requirements imposed on business development companies by the 1940 Act could cause the SEC to bring an enforcement action against us. For additional information on the qualification requirements of a business development company, see “Regulation.”

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 prior to receiving the related 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 generally will 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.

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

23

Table of Contents

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. Under such circumstances, 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. 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. 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 facilities limit 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, changes in our portfolio composition, 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

24

Table of Contents

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 realized gains are reduced by amounts paid pursuant to the warrant participation agreement.

Citigroup, a former credit facility provider to Hercules, has an equity participation right through a warrant participation agreement on the pool of loans and certain warrants formerly collateralized under its then existing credit facility (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 year ended December 31, 2011, the Company recorded an increase on participation liability and decreased its unrealized gains by a net amount of approximately $217,000 for Citigroup’s participation. Since inception of the agreement, we have paid Citigroup approximately $1.1 million under the warrant participation agreement thereby reducing our realized gains. In addition, our realized gains will be reduced by the amounts owed to Citigroup under the warrant participation agreement. The value of Citigroup’s participation right on unrealized gains in the related equity investments since inception of the agreement was approximately $715,000 at December 31, 2011 and is included in accrued liabilities and decreased the unrealized gain recognized by us at December 31, 2011. Citigroup’s rights under the warrant participation agreement increase our cost of borrowing and reduce our realized gains.

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

Under our borrowings and credit facilities, including our Union Bank and Wells credit facilities, current lenders have, and any future lender or lenders may 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. Our current credit facilities and borrowings also subject us to various financial and operating covenants, including, but not limited to, maintaining certain financial ratios and minimum tangible net worth amounts. Future credit facilities and borrowings will likely subject us to similar or additional covenants. In addition, we may grant a securities interest in our assets in connection with any such credit facilities and borrowings.

Our current credit facilities generally 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. In addition, such credit facilities require or are expected to require the repayment of all outstanding debt on the maturity which may disrupt our business and potentially the business of our portfolio companies that are financed through the facilities. An event of default under these facilities would likely result, among other things, in termination of the availability of further funds under the facilities and accelerated maturity dates for all amounts outstanding under the facilities, which would likely disrupt our business and, potentially, the business of the portfolio companies whose loans we finance through the facilities. This could reduce our revenues and, by delaying any cash payment allowed to us under our facilities 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.

Table of Contents

The terms of future available financing may place limits on our financial and operation flexibility. If we are unable to obtain sufficient capital in the future, we may be forced to reduce or discontinue our operations, not be able to make new investments, or otherwise respond to changing business conditions or competitive pressures.

In addition to regulatory restrictions that restrict our ability to raise capital, the Wells Facility, the Union Bank Facility and the Convertible Senior Notes, the April 2019 Notes and September 2019 Notes contain various covenants which, if not complied with, could accelerate repayment under the facility or require us to repurchase the Convertible Senior Notes, the April 2019 Notes or the September 2019 Notes, thereby materially and adversely affecting our liquidity, financial condition, results of operations and ability to pay dividends.

The credit agreements governing the Wells Facility, Union Bank Facility, the Convertible Senior Notes, the April 2019 Notes and the September 2019 Notes require 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. Our ability to continue to comply with these covenants in the future depends on many factors, some of which are beyond our control. 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 under the Wells Facility and the Union Bank Facility or the trustee or holders under the Convertible Senior Notes, the April 2019 Notes and the September 2019 Notes, could accelerate repayment under the facilities or the Convertible Senior Notes, the April 2019 Notes or the September 2019 Notes and thereby have a material adverse impact on our liquidity, financial condition, results of operations and ability to pay dividends. In addition, holders of the Convertible Senior Notes will have the right to require us to repurchase the Convertible Senior Notes upon the occurrence of a fundamental change at a repurchase price equal to 100% of their principal amount, plus accrued and unpaid interest, if any. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases. See “Management’s Discussion and Analysis of Results of Operations and Financial Condition—Borrowings.”

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

Our wholly-owned subsidiaries HT II and HT III are licensed to act as SBICs and are regulated by the SBA. As of June 30, 2012, HT II’s and HT III’s portfolio companies accounted for approximately 24.9% and 19.4%, respectively, of our total portfolio. The SBIC licenses allow our SBIC subsidiaries to obtain leverage by issuing SBA-guaranteed debentures, subject to the issuance of a capital commitment by the SBA and other customary procedures. The SBA regulations require, among other things, that a licensed SBIC be examined periodically and audited by an independent auditor to determine the SBIC’s compliance with the relevant SBA regulations.

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 25.0% 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 and HT III 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,

26

Table of Contents

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 either HT II or HT III fail to comply with applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit HT II’s or HT III’s use of debentures, declare outstanding debentures immediately due and payable, and/ or limit HT II or HT III from making new investments. Such actions by the SBA would, in turn, negatively affect us because HT II and HT III are our wholly owned subsidiaries. HT II and HT III were in compliance with the terms of the SBIC’s leverage as of December 31, 2011 as a result of having sufficient capital as defined under the SBA regulations. See “Regulation—Small Business Administration Regulations.”

Our wholly-owned SBIC subsidiaries may be unable to make distributions to us that will enable us to meet or maintain RIC status, which could result in the imposition of an entity-level tax.

In order for us to continue to qualify for RIC tax treatment and to minimize corporate-level taxes, we will be required to distribute substantially all of our net ordinary income and net capital gain income, including income from certain of our subsidiaries, which includes the income from our SBIC subsidiaries. We will be partially dependent on our SBIC subsidiaries for cash distributions to enable us to meet the RIC distribution requirements. Our SBIC subsidiaries may be limited by the Small Business Investment Act of 1958, and SBA regulations governing SBICs, from making certain distributions to us that may be necessary to maintain our status as a RIC. We may have to request a waiver of the SBA’s restrictions for our SBIC subsidiaries to make certain distributions to maintain our RIC status. We cannot assure you that the SBA will grant such waiver. If our SBIC subsidiaries are unable to obtain a waiver, compliance with the SBA regulations may result in loss of RIC tax treatment and a consequent imposition of an entity-level tax on us. See “Regulation—Small Business Administration Regulations.”

There is no assurance that HT II or HT III will be able to draw up to the maximum limit available under the SBIC program.

On September 27, 2006, HT II received a license to operate as a SBIC under the SBIC program and is able to borrow funds from the SBA against eligible investments and additional contributions to regulatory capital. As of June 30, 2012, HT II had the potential to borrow up to $125.0 million of SBA-guaranteed debentures under the SBIC program. With our net investment of $75.0 million in HT II as of June 30, 2012, HT II has the capacity to issue a total of $125.0 million of SBA guaranteed debentures, subject to SBA approval, of which $100.7 million is outstanding as of June 30, 2012.

On May 26, 2010, HT III received a license to operate as a SBIC under the SBIC program and is able to borrow funds from the SBA against eligible investments and additional contributions to regulatory capital. As of June 30, 2012, HT III had the potential to borrow up to $100.0 million of SBA-guaranteed debentures under the SBIC program. With our net investment of $50.0 million in HT III as of June 30, 2012, HT III has the capacity to issue a total of $100.0 million of SBA guaranteed debentures, subject to SBA approval, of which $100.0 million was outstanding as of June 30, 2012.

As of June 30, 2012, there was $200.7 million principal amount of indebtedness outstanding incurred by our SBIC subsidiaries. Access to the remaining leverage is subject to SBA approval and compliance with SBA regulations.

There is no assurance that HT II or HT III will be able to draw up to the maximum limit available under the SBIC program.

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

27

Table of Contents

comply with the source of income, asset 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 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, SBICs, 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 Current Economic and Market Conditions

Capital markets may experience periods of disruption and instability and we cannot predict when these conditions will occur. Such market conditions could materially and adversely affect debt and equity capital markets in the United States and abroad, which could have a negative impact on our business, financial condition and results of operations.

The global capital markets have experienced a period of disruption as evidenced by a lack of liquidity in the debt capital markets, write-offs in the financial services sector, the re-pricing of credit risk and the failure of certain major financial institutions. Despite actions of the United States federal government and foreign governments, these events contributed to worsening general economic conditions that have materially and adversely impacted the broader financial and credit markets and reduced the availability of debt and equity capital for the market as a whole and financial services firms in particular. While indicators suggest improvement in the capital markets, these conditions could deteriorate in the future. During such market disruptions, we may have difficulty raising debt or equity capital especially as a result of regulatory constraints.

28

Table of Contents

Market conditions may in the future make it difficult to extend the maturity of or refinance our existing indebtedness and any failure to do so could have a material adverse effect on our business. The illiquidity of our investments may make it difficult for us to sell such investments if required. As a result, we may realize significantly less than the value at which we have recorded our investments. In addition, significant changes in the capital markets, including the disruption and volatility, have had, and may in the future have, a negative effect on the valuations of our investments and on the potential for liquidity events involving our investments. An inability to raise capital, and any required sale of our investments for liquidity purposes, could have a material adverse impact on our business, financial condition and results of operations.

The impact of recent financial reform legislation on us is uncertain.

In light of current conditions in the U.S. and global financial markets and the U.S. and global economy, legislators, the presidential administration and regulators have increased their focus on the regulation of the financial services industry. The Dodd-Frank Act institutes a wide range of reforms that will have an impact on all financial institutions. Many of these provisions are subject to rule making procedures and studies that will be conducted in the future. Accordingly, we cannot predict the effect the Dodd-Frank Act or its implementing regulations will have on our business, results of operations or financial condition.

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.

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.

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.

As of December 31, 2011, we did not have any outstanding borrowings under the Union Bank Facility and had approximately $10.2 million of borrowings outstanding under the Wells Facility. In addition, as of December 31, 2011, we had approximately $225.0 million principal amount of indebtedness outstanding incurred by our SBIC subsidiaries and $75.0 million of Senior Convertible Notes payable. Available borrowing capacity under these facilities as of December 31, 2011 was $119.8 million and subject to terms and conditions and approvals of the SBA.

Depending on funding requirements, we may need to raise additional capital to meet our unfunded commitments either through equity offerings or through additional borrowings.

As of September 10, 2012, we had unfunded debt commitments of approximately $69.8 million. Since these commitments may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements or future earning assets. Closed commitments generally fund 70-80% of the committed amount in aggregate over the life of the commitment. We intend to use cash flow from normal and early principal repayments, SBA debentures, our Wells Facility, our Union Bank Facility and proceeds from the Convertible Senior Notes, the April 2019 Notes and September 2019 Notes to fund these commitments. However, there can be no assurance that we will have sufficient capital available to fund these commitments as they come due.

Risks Related to Our Investments

Our investments are concentrated in certain industries and in a 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, 2012, approximately 61.9% of the fair value of our portfolio was composed of investments in five industries: 18.9% was composed of investments in the drug discovery and development industry, 12.2% was composed of investments in the software industry, 11.6% was composed of investments in the clean technology industry, 9.7% was composed of investments in the internet drug delivery industry; and 9.5% was composed of investments in the internet consumer and business services industry.

Our investments may be 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, changes in regulatory and governmental programs 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. Overcapacity in technology-related industries, together with cyclical economic downturns, may result 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 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.

A natural disaster may also impact the operations of our portfolio companies, including our technology- related portfolio companies. The nature and level of natural disasters cannot be predicted and may be exacerbated by global climate change. A portion of our technology-related portfolio companies rely on items assembled or produced in areas susceptible to natural disasters, and may sell finished goods into markets susceptible to natural disasters. A major disaster, such as an earthquake, tsunami, flood or other catastrophic event could result in disruption to the business and operations of our technology-related portfolio companies.

We will invest in technology-related companies that are reliant on U.S. and foreign regulatory and governmental programs. Any material changes or discontinuation, due to change in administration or U.S. Congress or otherwise could have a material adverse effect on the operations of a portfolio company in these industries and, in turn, impair our ability to timely collect principal and interest payments owed to us to the extent applicable.

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.

Our investments in the clean technology industry are subject to many risks, including volatility, intense competition, unproven technologies, periodic downturns and potential litigation.

Our investments in clean technology, or cleantech, companies are subject to substantial operational risks, such as underestimated cost projections, unanticipated operation and maintenance expenses, loss of government subsidies, and inability to deliver cost-effective alternative energy solutions compared to traditional energy products. In addition, energy companies employ a variety of means of increasing cash flow, including increasing utilization of existing facilities, expanding operations through new construction or acquisitions, or securing additional long-term contracts. Thus, some energy companies may be subject to construction risk, acquisition risk or other risks arising from their specific business strategies. Furthermore, production levels for solar, wind and other renewable energies may be dependent upon adequate sunlight, wind, or biogas production, which can vary from market to market and period to period, resulting in volatility in production levels and profitability. In addition, our cleantech companies 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 clean technology companies can and often do fluctuate suddenly and dramatically and the markets in which clean technology companies operate are generally characterized by abrupt business cycles and intense competition. Demand for cleantech and renewable energy is also influenced by the available supply and prices for other energy products, such as coal, oil and natural gases.

31

Table of Contents

A change in prices in these energy products could reduce demand for alternative energy. Our investments in cleantech companies also face potential litigation, including significant warranty and product liability claims, as well as class action and government claims arising from the increased attention to the industry from the failure of Solyndra. Such litigation could adversely affect the business and results of operations of our cleantech portfolio companies. There is also particular uncertainty about whether agreements providing incentives for reductions in greenhouse gas emissions, such as the Kyoto Protocol, will continue and whether countries around the world will enact or maintain legislation that provides incentives for reductions in greenhouse gas emissions, without which such investments in clean technology dependent portfolio companies may not be economical or financing for such projects may become unavailable. As a result, these portfolio company investments face considerable risk, including the risk that favorable regulatory regimes expire or are adversely modified. This could, in turn, materially adversely affect the value of the clean technology companies in our portfolio.

Cleantech companies are subject to extensive government regulation and certain other risks particular to the sectors in which they operate and our business and growth strategy could be adversely affected if government regulations, priorities and resources impacting such sectors change or if our portfolio companies fail to comply with such regulations.

As part of our investment strategy, we plan to invest in portfolio companies in Cleantech sectors that may be subject to extensive regulation by foreign, U.S. federal, state and/or local agencies. Changes in existing laws, rules or regulations, or judicial or administrative interpretations thereof, or new laws, rules or regulations could have an adverse impact on the business and industries of our portfolio companies. In addition, changes in government priorities or limitations on government resources could also adversely impact our portfolio companies. We are unable to predict whether any such changes in laws, rules or regulations will occur and, if they do occur, the impact of these changes on our portfolio companies and our investment returns. Furthermore, if any of our portfolio companies fail to comply with applicable regulations, they could be subject to significant penalties and claims that could materially and adversely affect their operations. Our portfolio companies may be subject to the expense, delay and uncertainty of the regulatory approval process for their products and, even if approved, these products may not be accepted in the marketplace.

In addition, there is considerable uncertainty about whether foreign, U.S., state and/or local governmental entities will enact or maintain legislation or regulatory programs that mandate reductions in greenhouse gas emissions or provide incentives for Cleantech companies. Without such regulatory policies, investments in Cleantech companies may not be economical and financing for Cleantech companies may become unavailable, which could materially adversely affect the ability of our portfolio companies to repay the debt they owe to us. Any of these factors could materially and adversely affect the operations and financial condition of a portfolio company and, in turn, the ability of the portfolio company to repay the debt they owe to us.

Our investments in the life science industry are subject to extensive government regulation, litigation risk and certain other risks particular to that industry.

We have invested and plan to continue investing in companies in the life science industry that are subject to extensive regulation by the Food and Drug Administration, or the FDA, and to a lesser extent, other federal, state and other foreign agencies. If any of these portfolio companies fail to comply with applicable regulations, they could be subject to significant penalties and claims that could materially and adversely affect their operations. Portfolio companies that produce medical devices or drugs are subject to the expense, delay and uncertainty of the regulatory approval process for their products and, even if approved, these products may not be accepted in the marketplace. In addition, governmental budgetary constraints effecting the regulatory approval process, new laws, regulations or judicial interpretations of existing laws and regulations might adversely affect a portfolio company in this industry. Portfolio companies in the life science industry may also have a limited number of suppliers of necessary components or a limited number of manufacturers for their products, and therefore face a risk of disruption to their manufacturing process if they are unable to find alternative suppliers when needed. Any of these factors could materially and adversely affect the operations of a portfolio company in this industry and, in turn, impair our ability to timely collect principal and interest payments owed to us.

Our investments in the drug discovery industry are subject to numerous risks, including competition, extensive government regulation, product liability and commercial difficulties.

Our investments in the drug discovery industry are subject to numerous risks. The successful and timely implementation of the business model of our drug discovery portfolio companies depends on their ability to adapt to changing technologies and introduce new products. As competitors continue to introduce competitive products, the development and acquisition of innovative products and technologies that improve efficacy, safety, patient’s and clinician’s ease of use and cost-effectiveness are important to the success of such portfolio companies. The success of new product offerings will depend on many factors, including the ability to properly anticipate and satisfy customer needs, obtain regulatory approvals on a timely basis, develop and manufacture products in an economic and timely manner, obtain or maintain advantageous positions with respect to intellectual property, and differentiate products from those of competitors. Failure by our portfolio companies to introduce planned products or other new products or to introduce products on schedule could have a material adverse effect on our business, financial condition and results of operations.

Further, the development of products by drug discovery companies requires significant research and development, clinical trials and regulatory approvals. The results of product development efforts may be affected by a number of factors, including the ability to innovate, develop and manufacture new products, complete clinical trials, obtain regulatory approvals and reimbursement in the US and abroad, or gain and maintain market approval of products. In addition, regulatory review processes by U.S. and foreign agencies may extend longer than anticipated as a result of decreased funding and tighter fiscal budgets. Further, patents attained by others can preclude or delay the commercialization of a product. There can be no assurance that any products now in development will achieve technological feasibility, obtain regulatory approval, or gain market acceptance. Failure can occur at any point in the development process, including after significant funds have been invested. Products may fail to reach the market or may have only limited commercial success because of efficacy or safety concerns, failure to achieve positive clinical outcomes, inability to obtain necessary regulatory approvals, failure to achieve market adoption, limited scope of approved uses, excessive costs to manufacture, the failure to establish or maintain intellectual property rights, or the infringement of intellectual property rights of others.

Future legislation, and/or regulations and policies adopted by the FDA or other U.S. or foreign regulatory authorities may increase the time and cost required by some of our portfolio companies to conduct and complete clinical trials for the product candidates that they develop, and there is no assurance that these companies will obtain regulatory approval to market and commercialize their products in the U.S. and in foreign countries

The FDA has established regulations, guidelines and policies to govern the drug development and approval process, as have foreign regulatory authorities, which affect some of our portfolio companies. Any change in regulatory requirements due to the adoption by the FDA and/or foreign regulatory authorities of new legislation, regulations, or policies may require some of our portfolio companies to amend existing clinical trial protocols or add new clinical trials to comply with these changes. Such amendments to existing protocols and/or clinical trial applications or the need for new ones, may significantly impact the cost, timing and completion of the clinical trials.

In addition, increased scrutiny by the U.S. Congress of the FDA’s and other authorities approval processes may significantly delay or prevent regulatory approval, as well as impose more stringent product labeling and post-marketing testing and other requirements. Foreign regulatory authorities may also increase their scrutiny of approval processes resulting in similar delays. Increased scrutiny and approvals processes may limit the ability of our portfolio companies to market and commercialize their products in the U.S. and in foreign countries.

Changes in healthcare laws and other regulations applicable to some of our portfolio companies’ businesses may constrain their ability to offer their products and services.

Changes in healthcare or other laws and regulations applicable to the businesses of some of our portfolio companies may occur that could increase their compliance and other costs of doing business, require significant

33

Table of Contents

systems enhancements, or render their products or services less profitable or obsolete, any of which could have a material adverse effect on their results of operations. There has also been an increased political and regulatory focus on healthcare laws in recent years, and new legislation could have a material effect on the business and operations of some of our portfolio companies.

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 business development company, 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.

If macro and micro market conditions should deteriorate, 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 slowdowns 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 have a material adverse effect on our results of operations.

Many of our portfolio companies may be susceptible to economic slowdowns or recessions in both the U.S. and foreign countries, and may be unable to repay our loans during such periods. In such periods, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease. 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 materially adversely affect our financial condition and operating results.

Generally, 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

34

Table of Contents

which we are unable or unwilling to provide, or they may be subject to adverse developments unrelated to the technologies they acquire.

The business, financial condition and results of operations of our portfolio companies could be adversely affected by worldwide economic conditions, as well as political and economic conditions in the countries in which they conduct business.

The business and operating results of our portfolio companies may be impacted by worldwide economic conditions. Although the U.S. economy has in recent quarters shown signs of recovery from the 2008–2009 global recession, the strength and duration of any economic recovery will be impacted by worldwide economic growth. For instance, a number of recent reports indicate that growth in China and other emerging markets may be slowing relative to historical growth rates. The significant debt in U.S. and European countries is expected to hinder growth in those countries for the foreseeable future. Multiple factors relating to the international operations of some of our portfolio companies and to particular countries in which they operate could negatively impact their business, financial condition and results of operations.

Some of the products of our portfolio companies are developed, manufactured, assembled, tested or marketed outside the U.S. Any conflict or uncertainty in these countries, including due to natural disasters, public health concerns, political unrest or safety concerns, could harm their business, financial condition and results of operations. In addition, if the government of any country in which their products are developed, manufactured or sold sets technical or regulatory standards for products developed or manufactured in or imported into their country that are not widely shared, it may lead some of their customers to suspend imports of their products into that country, require manufacturers or developers in that country to manufacture or develop products with different technical or regulatory standards and disrupt cross-border manufacturing, marketing or business relationships which, in each case, could harm their businesses.

Any unrealized losses we experience on our investment portfolio may be an indication of future realized losses, which could reduce our income available for distribution and could materially adversely affect our ability to service our outstanding borrowings.

As a business development company, 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 losses 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 and could materially adversely affect our ability to service our outstanding borrowings.

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

A 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 lack of IPO opportunities for venture capital-backed companies can also cause 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.

Economic slowdowns or recessions could impair the value of the collateral for our loans to our portfolio companies, increase our funding costs, limit our access to the credit and capital markets, impair the ability of a portfolio company to satisfy covenants imposed by its lenders and consequently increase the possibility of an adverse effect on our business, financial condition and results of operations.

Many of our portfolio companies are susceptible to economic slowdowns or recessions in both the U.S. and foreign countries and may be unable to repay our loans during such periods. Therefore, our non-performing

36

Table of Contents

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 may constitute 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.

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. 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 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 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 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 and our results of operations and financial condition.

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 and our results of operations and financial condition.

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

38

Table of Contents

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. Our total investments at value in foreign companies were approximately $14.3 million or 1.9% of total assets at December 31, 2011. 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 and may be needed if necessary regulatory review processes are extended or approvals not obtained.

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. This may have a significant impact if the companies are unable to obtain certain federal, state or foreign agency approval for their products or the marketing thereof, of if regulatory review processes extend longer than anticipated, and the companies need continued funding for their operations during these times. 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

39

Table of Contents

used when making the initial investment. We cannot assure you that we will have sufficient funds to make any necessary additional investments, which could adversely affect our success and result in the loss of a substantial portion or all of our investment in a portfolio company.

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

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

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. 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. Moreover, a follow-on investment may limit the number of companies in which we can make initial investments. In determining whether to make a follow-on investment, our management will exercise its business judgment and apply criteria similar to those used when making the initial investment. There is no assurance that we will make, or will have sufficient funds to make, follow-on investments and this could adversely affect our success and result in the loss of a substantial portion or all of our investment in a portfolio company.

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 and could adversely affect our ability to service our outstanding borrowings.

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 and could materially adversely affect our ability to service our outstanding borrowings.

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

40

Table of Contents

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 may not realize expected returns on warrants received in connection with our debt investments.

We generally receive warrants in connection with our debt investments. At December 31, 2011, we held warrant positions received in connection with our debt investments in approximately 4.6% of our total portfolio investments. If we do not receive the returns that are anticipated on the warrants, our investment returns on our portfolio companies, and the value of an investment in us, may be lower than expected.

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

Generally, 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

41

Table of Contents

that a portfolio company in which we invest may make business decisions with which we disagree and the management of such company, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors.

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

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

At June 30, 2012, approximately 63.1% of our portfolio company loans were secured by a first priority security in all of the assets of the portfolio company (including their intellectual property), 33.8% of portfolio company loans were to portfolio companies that were prohibited from pledging or encumbering their intellectual property, 2.3% of portfolio company loans had a first priority security in only their intellectual property, and 0.8% of portfolio company loans had an equipment only lien.

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

42

Table of Contents

limited financial resources, may be unable to meet future obligations and may go bankrupt. This could negatively impact our ability to pay dividends, could adversely affect our results of operation and financial condition and cause the loss of all or part of your investment.

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. These investments represent approximately 10.5% of the outstanding balance of our portfolio as of June 30, 2012. 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.

Risks Related to Our Securities

Investing in our securities 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 securities 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. 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 our charter and bylaws could deter takeover attempts and have an adverse impact on the price of our securities.

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. 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

43

Table of Contents

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. See “Description of our Capital Stock.”

We may again obtain the approval of our stockholders to issue shares of our common stock at prices below the then current net asset value per share of our common stock. If we receive such approval from the stockholders, we may again issue shares of our common stock at a price below the then current net asset value per share of common stock. Any such issuance could materially dilute your interest in our common stock and reduce our net asset value per share.

We may again obtain the approval of our stockholders to issue shares of our common stock at prices below the then current net asset value per share of our common stock. Such approval has allowed and may again allow us to access the capital markets in a way that we typically are unable to do as a result of restrictions that, absent stockholder approval, apply to business development companies under the 1940 Act. Any decision to sell shares of our common stock below the then current net asset value per share of our common stock is subject to the determination by our board of directors that such issuance and sale is in our and our stockholders’ best interests.

Any sale or other issuance of shares of our common stock at a price below net asset value per share has resulted and will continue to result in an immediate dilution to your interest in our common stock and a reduction of our net asset value per share. This dilution would occur as a result of 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. Because the number of future shares of common stock that may be issued below our net asset value per share and the price and timing of such issuances are not currently known, we cannot predict the actual dilutive effect of any such issuance. We also cannot determine the resulting reduction in our net asset value per share of any such issuance at this time. We caution you that such effects may be material, and we undertake to describe all the material risks and dilutive effects of any offering that we make at a price below our then current net asset value in the future in a prospectus supplement issued in connection with any such offering. We cannot predict whether shares of our common stock will trade above, at or below our net asset value.

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.

We are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our common stock, at a price below the current net asset value of the common stock, or sell warrants, options or rights to acquire such common stock, at a price below the current net asset value of the common stock if our board of directors determines that such sale is in the best interests of the Company and our stockholders have approved the practice of making such sales.

At our Annual Meeting of Stockholders on May 30, 2012, our 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

44

Table of Contents

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, 2012.

Our shares may trade at discounts from net asset value or at premiums that are unsustainable over the long term.

Shares of business development companies may trade at a market price that is less than the net asset value that is attributable to those shares. Our shares have traded above and below our NAV. The possibility that our shares of common stock will trade at a discount from net asset value or at a premium that is unsustainable over the long term is separate and distinct from the risk that our net asset value will decrease. It is not possible to predict whether our shares will trade at, above or below net asset value in the future.

We may allocate the net proceeds from an offering in ways with which you may not agree.

We have significant flexibility in investing the net proceeds of an offering and may use the net proceeds from an offering in ways with which you may not agree or for purposes other than those contemplated at the time of the offering.

If we issue preferred stock, debt securities or convertible debt securities, the net asset value and market value of our common stock may become more volatile.

We cannot assure you that the issuance of preferred stock and/or debt securities would result in a higher yield or return to the holders of our common stock. The issuance of preferred stock, debt securities or convertible debt would likely cause the net asset value and market value of our common stock to become more volatile. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our common stock would be reduced. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to exceed the net rate of return on our portfolio, the use of leverage would result in a lower rate of return to the holders of common stock than if we had not issued the preferred stock or debt securities. Any decline in the net asset value of our investment would be borne entirely by the holders of our common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in net asset value to the holders of our common stock than if we were not leveraged through the issuance of preferred stock. This decline in net asset value would also tend to cause a greater decline in the market price for our common stock.

There is also a risk that, in the event of a sharp decline in the value of our net assets, we would be in danger of failing to maintain required asset coverage ratios which may be required by the preferred stock, debt securities, convertible debt or units or of a downgrade in the ratings of the preferred stock, debt securities, convertible debt or units or our current investment income might not be sufficient to meet the dividend requirements on the preferred stock or the interest payments on the debt securities. If we do not maintain our required asset coverage ratios, we may not be permitted to declare dividends. In order to counteract such an event, we might need to liquidate investments in order to fund redemption of some or all of the preferred stock, debt securities or convertible debt. In addition, we would pay (and the holders of our common stock would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock, debt securities, convertible debt or any combination of these securities. Holders of preferred stock, debt securities or convertible debt may have different interests than holders of common stock and may at times have disproportionate influence over our affairs.

Holders of any preferred stock that we may issue will have the right to elect members of the board of directors and have class voting rights on certain matters.

The 1940 Act requires that holders of shares of preferred stock must be entitled as a class to elect two directors at all times and to elect a majority of the directors if dividends on such preferred stock are in arrears by two years or more, until such arrearage is eliminated. In addition, certain matters under the 1940 Act require the

45

Table of Contents

separate vote of the holders of any issued and outstanding preferred stock, including changes in fundamental investment restrictions and conversion to open-end status and, accordingly, preferred stockholders could veto any such changes. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of our common stock and preferred stock, both by the 1940 Act and by requirements imposed by rating agencies, might impair our ability to maintain our qualification as a RIC for U.S. federal income tax purposes.

Your interest in us may be diluted if you do not fully exercise your subscription rights in any rights offering. In addition, if the subscription price is less than our net asset value per share, then you will experience an immediate dilution of the aggregate net asset value of your shares.

In the event we issue subscription rights, stockholders who do not fully exercise their subscription rights should expect that they will, at the completion of a rights offering pursuant to this prospectus, own a smaller proportional interest in us than would otherwise be the case if they fully exercised their rights. We cannot state precisely the amount of any such dilution in share ownership because we do not know at this time what proportion of the shares will be purchased as a result of such rights offering.

In addition, if the subscription price is less than the net asset value per share of our common stock, then our stockholders would experience an immediate dilution of the aggregate net asset value of their shares as a result of the offering. The amount of any decrease in net asset value is not predictable because it is not known at this time what the subscription price and net asset value per share will be on the expiration date of a rights offering or what proportion of the shares will be purchased as a result of such rights offering. Such dilution could be substantial.

The trading market or market value of our publicly issued debt securities may fluctuate.

Our publicly issued debt securities may or may not have an established trading market. We cannot assure you that a trading market for our publicly issued debt securities will ever develop or be maintained if developed. In addition to our creditworthiness, many factors may materially adversely affect the trading market for, and market value of, our publicly issued debt securities. These factors include, but are not limited to, the following:

Terms relating to redemption may materially adversely affect your return on any debt securities that we may issue.

If your debt securities are redeemable at our option, we may choose to redeem your debt securities at times when prevailing interest rates are lower than the interest rate paid on your debt securities. In addition, if your debt securities are subject to mandatory redemption, we may be required to redeem your debt securities also at times when prevailing interest rates are lower than the interest rate paid on your debt securities. In this

46

Table of Contents

circumstance, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as your debt securities being redeemed.

Our credit ratings may not reflect all risks of an investment in our debt securities.

Our credit ratings are an assessment by third parties of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of our debt securities. Our credit ratings, however, may not reflect the potential impact of risks related to market conditions generally or other factors discussed above on the market value of or trading market for the publicly issued debt securities.

Investors in offerings of our common stock will likely incur immediate dilution upon the closing of such offering.

We generally expect the public offering price of any offering of shares of our common stock to be higher than the book value per share of our outstanding common stock (unless we offer shares pursuant to a rights offering or after obtaining prior approval for such issuance from our stockholders and our independent directors). Accordingly, investors purchasing shares of common stock in offerings pursuant to this prospectus may pay a price per share that exceeds the tangible book value per share after such offering.

Our stockholders will experience dilution in their ownership percentage if they opt out of our dividend reinvestment plan.

All dividends declared in cash payable to stockholders that are participants in our dividend reinvestment plan are automatically reinvested in shares of our common stock. As a result, our stockholders that opt out of our dividend reinvestment plan will experience dilution in their ownership percentage of our common stock over time.

Our stockholders may experience dilution upon the conversion of the Convertible Notes.

The Convertible Senior Notes are convertible into shares of our common stock beginning October 15, 2015, or, under certain circumstances, earlier. Upon conversion of the Convertible Notes, we have the choice to pay or deliver, as the case may be, at our election, cash, shares of our common stock or a combination of cash and shares of our common stock. The current conversion price of the Convertible Senior Notes is approximately $11.89 per share of common stock, in each case subject to adjustment in certain circumstances. If we elect to deliver shares of common stock upon a conversion at the time our tangible book value per share exceeds the conversion price in effect at such time, our stockholders may incur dilution. In addition, our stockholders will experience dilution in their ownership percentage of common stock upon our issuance of common stock in connection with the conversion of the Convertible Senior Notes and any dividends paid on our common stock will also be paid on shares issued in connection with such conversion after such issuance.

Our common stock price has been and continues to be volatile and may decrease substantially.

As with any company, the price of our common stock will fluctuate with market conditions and other factors, which include, but are not limited to, the following:

47

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.

FORWARD-LOOKING STATEMENTS

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.

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 our securities for funding investments in debt and equity securities in accordance with our investment objective 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 securities 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.

PRICE RANGE OF COMMON STOCK AND DISTRIBUTIONS

Our common stock is traded on the NYSE 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 for those periods prior to April 30, 2012 and the NYSE thereafter, the 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 October 4, 2012 was $11.09 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.
