Exhibit 99.1

INVESTMENT MANAGEMENT AGREEMENT (this “Agreement”), dated as of March 6, 2015, between BlackRock Capital Investment Corporation, a Delaware corporation (the “BDC”), and BlackRock Advisors, LLC, a Delaware limited liability company (the “Advisor”).

WHEREAS, Advisor has agreed to furnish investment advisory services to the BDC, a closed-end management company that has elected to be regulated as a business development company under the Investment Company Act of 1940, as amended (the “1940 Act”);

WHEREAS, this Agreement has been approved in accordance with the provisions of the 1940 Act, and the Advisor is willing to furnish such services upon the terms and conditions herein set forth;

NOW, THEREFORE, in consideration of the mutual premises and covenants herein contained and other good and valuable consideration, the receipt of which is hereby acknowledged, it is agreed by and between the parties hereto as follows:

1. In General . The Advisor agrees, all as more fully set forth herein, to act as investment advisor to the BDC with respect to the investment of the BDC’s assets and to supervise and arrange for the day-to-day operations of the BDC and the purchase of securities for and the sale of securities held in the investment portfolio of the BDC.

2. Duties and Obligations of the Advisor with Respect to Investment of Assets of the BDC .

(a) Subject to the succeeding provisions of this paragraph and subject to the direction and control of the BDC’s Board of Directors, the Advisor shall (i) act as investment advisor for and supervise and manage the investment and reinvestment of the BDC’s assets and in connection therewith have complete discretion in purchasing and selling securities and other assets for the BDC and in voting, exercising consents and exercising all other rights appertaining to such securities and other assets on behalf of the BDC; (ii) supervise continuously the investment program of the BDC and the composition of its investment portfolio; (iii) arrange, subject to the provisions of Section 3(b) hereof, for the purchase and sale of securities and other assets held in the investment portfolio of the BDC; and (iv) oversee the administration of all aspects of the BDC’s business and affairs and provide, or arrange for others whom it believes to be competent to provide, certain services as specified in paragraph (b) below. Nothing contained herein shall be construed to restrict the BDC’s right to hire its own employees or to contract for administrative services to be performed by third parties, including but not limited to, the calculation of the net asset value of the BDC’s shares.

(b) Except to the extent provided for directly by the BDC, the specific services to be provided or arranged for by the Advisor for the BDC pursuant to paragraph (a)(iv) above are (i) maintaining the BDC’s books and records, to the extent not maintained by the BDC’s custodian, transfer agent and dividend disbursing agent in accordance with applicable laws and regulations; (ii) initiating all money transfers to the BDC’s custodian and from the BDC’s custodian for the payment of the BDC’s expenses, investments and dividends; (iii) reconciling account information and balances among the BDC’s custodian, transfer agent and dividend disbursing agent; (iv) preparing all governmental filings by the BDC and all reports by the BDC to its shareholders; (v) supervising the calculation of the net asset value of the BDC’s shares; and (vi) preparing notices and agendas for meetings of the BDC’s shareholders and the BDC’s Board of Directors as well as minutes of such meetings in all matters required by applicable law to be acted upon by the Board of Directors.

(c) In the performance of its duties under this Agreement, the Advisor shall at all times use all reasonable efforts to conform to, and act in accordance with, any requirements imposed by (i) the provisions of the 1940 Act, and of any rules or regulations in force thereunder; (ii) any other applicable provision of law; (iii) the provisions of the Certificate of Incorporation and the By-Laws of the BDC, as such documents are amended from time to time; (iv) the investment objectives, policies and restrictions applicable to the BDC as set forth in the BDC’s Registration Statement on Form N-2 (the “Registration Statement”); and (v) any policies and determinations of the Board of Directors of the BDC.

(d) The Advisor will seek to provide qualified personnel to fulfill its duties hereunder and, except as set forth in the following sentence, will bear all costs and expenses incurred in connection with its investment advisory duties thereunder. The BDC shall reimburse the Advisor for all direct and indirect cost and expenses incurred by the Advisor (i) for office space rental, office equipment and utilities allocable to performance of investment advisory and non investment advisory administrative or operating services hereunder by the Advisor and (ii) allocable to any non-investment advisory administrative or operating services provided by the Advisor hereunder, including salaries, bonuses, health insurance, retirement benefits and all similar employment costs, such as office equipment and other overhead items. All allocations made pursuant to this paragraph (d) shall be made pursuant to allocation guidelines approved from time to time by the Board of Directors. The BDC shall also be responsible for the payment of all the BDC’s other expenses, including (i) payment of the fees payable to the Advisor under Section 8 and Section 9 hereof; (ii) organizational expenses; (iii) brokerage fees and commissions; (iv) taxes; (v) interest charges on borrowings; (vi) the cost of liability insurance or fidelity bond coverage for the BDC’s officers and employees, and directors’ and officers’ errors and omissions insurance coverage; (vii) legal, auditing and accounting fees and expenses; (viii) charges of the BDC’s administrator (if any), custodian, transfer agent and dividend disbursing agent and any other service providers; (ix) the BDC’s dues, fees and charges of any trade association of which the BDC is a member; (x) the expenses of printing, preparing and mailing proxies, stock certificates, reports, prospectuses, registration statements and other documents used by the BDC; (xi) expenses of registering and offering securities of the BDC under

2

applicable law; (xii) the expenses of holding shareholder meetings; (xiii) the compensation, including fees, of any of the BDC’s directors, officers or employees who are not affiliated persons of the Advisor; (xiv) all expenses of computing the BDC’s net asset value per share; (xv) litigation and indemnification and other extraordinary or non recurring expenses; and (xvi) all other non investment advisory expenses of the BDC.

(e) The Advisor shall give the BDC the benefit of its professional judgment and effort in rendering services hereunder, but neither the Advisor nor any of its officers, directors, employees, agents or controlling persons shall be liable for any act or omission or for any loss sustained by the BDC in connection with the matters to which this Agreement relates, except a loss resulting from willful misfeasance, bad faith or gross negligence in the performance of its duties, or by reason of its reckless disregard of its obligations and duties under this Agreement; provided, however, that the foregoing shall not constitute a waiver of any rights which the BDC may have which may not be waived under applicable law.

3. Covenants . (a) In the performance of its duties under this Agreement, the Advisor shall at all times conform to, and act in accordance with, any requirements imposed by: (i) the provisions of the 1940 Act and the Investment Advisers Act of 1940, as amended (the “Advisers Act”), and all applicable Rules and Regulations of the Securities and Exchange Commission (the “SEC”); (ii) any other applicable provision of law; (iii) the provisions of the Certificate of Incorporation and By-Laws of the BDC, as such documents are amended from time to time; (iv) the investment objectives and policies of the BDC as set forth in its Registration Statement; and (v) any policies and determinations of the Board of Directors of the BDC.

(b) In addition, the Advisor will:

(i) place orders either directly with the issuer or with any broker or dealer. Subject to the other provisions of this paragraph, in placing orders with brokers and dealers, the Advisor will attempt to obtain the best price and the most favorable execution of its orders. In placing orders, the Advisor will consider the experience and skill of the firm’s securities traders as well as the firm’s financial responsibility and administrative efficiency. Consistent with this obligation, the Advisor may select brokers on the basis of the research, statistical and pricing services they provide to the BDC and other clients of the Advisor. Information and research received from such brokers will be in addition to, and not in lieu of, the services required to be performed by the Advisor hereunder. A commission paid to such brokers may be higher than that which another qualified broker would have charged for effecting the same transaction, provided that the Advisor determines in good faith that such commission is reasonable in terms either of the transaction or the overall responsibility of the Advisor to the BDC and its other clients and that the total commissions paid by the BDC will be reasonable in relation to the benefits to the BDC over the long term. In addition, the Advisor is authorized to take into account the sale of shares of the BDC in allocating purchase and sale orders for portfolio securities to brokers or dealers (including brokers and dealers that are affiliated with the Advisor), provided that

3

the Advisor believes that the quality of the transaction and the commission are comparable to what they would be with other qualified firms. In no instance, however, will the BDC’s securities be purchased from or sold to the Advisor, or any affiliated person thereof, except to the extent permitted by the SEC or by applicable law;

(ii) maintain a policy and practice of conducting its investment advisory services hereunder independently of the commercial banking operations of its affiliates. When the Advisor makes investment recommendations for the BDC, its investment advisory personnel will not inquire or take into consideration whether the issuer of securities proposed for purchase or sale for the BDC’s account are customers of the commercial department of its affiliates; and

(iii) treat confidentially and as proprietary information of the BDC all records and other information relative to the BDC, and the BDC’s prior, current or potential shareholders, and will not use such records and information for any purpose other than performance of its responsibilities and duties hereunder, except after prior notification to and approval in writing by the BDC, which approval shall not be unreasonably withheld and may not be withheld where the Advisor may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities, or when so requested by the BDC.

4. Services Not Exclusive . Nothing in this Agreement shall prevent the Advisor or any officer, employee or other affiliate thereof from acting as investment advisor for any other person, firm or corporation, or from engaging in any other lawful activity, and shall not in any way limit or restrict the Advisor or any of its officers, employees or agents from buying, selling or trading any securities for its or their own accounts or for the accounts of others for whom it or they may be acting; provided , however , that the Advisor will undertake, and will cause its employees to undertake, no activities which, in its judgment, will adversely affect the performance of the Advisor’s obligations under this Agreement.

5. Books and Records . In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Advisor hereby agrees that all records which it maintains for the BDC are the property of the BDC and further agrees to surrender promptly to the BDC any such records upon the BDC’s request. The Advisor further agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records required to be maintained by Rule 31a-1 under the 1940 Act.

6. Agency Cross Transactions . From time to time, the Advisor or brokers or dealers affiliated with it may find themselves in a position to buy for certain of their brokerage clients (each an “Account”) securities which the Advisor’s investment advisory clients wish to sell, and to sell for certain of their brokerage clients securities which advisory clients wish to buy. Where one of the parties is an advisory client, the Advisor or the affiliated broker or dealer cannot participate in this type of transaction

4

(known as a cross transaction) on behalf of an advisory client and retain commissions from one or both parties to the transaction without the advisory client’s consent. This is because in a situation where the Advisor is making the investment decision (as opposed to a brokerage client who makes his own investment decisions), and the Advisor or an affiliate is receiving commissions from both sides of the transaction, there is a potential conflicting division of loyalties and responsibilities on the Advisor’s part regarding the advisory client. The SEC has adopted a rule under the Advisers Act, which permits the Advisor or its affiliates to participate on behalf of an Account in agency cross transactions if the advisory client has given written consent in advance. By execution of this Agreement, the BDC authorizes the Advisor or its affiliates to participate in agency cross transactions involving an Account. The BDC may revoke its consent at any time by written notice to the Advisor.

7. Expenses . During the term of this Agreement, the Advisor will bear all costs and expenses of its employees and any overhead incurred in connection with its duties hereunder and shall bear the costs of any salaries or Directors’ fees of any officers or Directors of the BDC who are affiliated persons (as defined in the 1940 Act) of the Advisor; provided that the Board of Directors of the BDC may approve reimbursement to the Advisor of the pro rata portion of the salaries, bonuses, health insurance, retirement benefits and all similar employment costs for the time spent on BDC operations (other than the provision of investment advice and administrative services required to be provided hereunder) of all personnel employed by the Advisor who devote substantial time to BDC operations or the operations of other investment companies advised by the Advisor.

8. Compensation of the Advisor During the First Two Years of this Agreement .

(a) From the date of this Agreement until the second anniversary of this Agreement, the provisions of this Section 8 shall apply with respect to the compensation of the Advisor.

(b) The Advisor, for its services to the BDC, will be entitled to receive a management fee (the “Management Fee”) from the BDC. The Management Fee will be calculated at an annual rate of 2.00% of total assets. The Management Fee will be paid quarterly in arrears based on the asset valuation as of the end of the prior quarter.

(c) For purposes of this Agreement, the assets and net assets of the BDC shall be calculated pursuant to the procedures adopted by resolutions of the Directors of the BDC for calculating the value of the BDC’s assets or delegating such calculations to third parties.

5

(d) The Advisor will be entitled to receive additional compensation (the “Incentive Fee”) if performance of the BDC exceeds the Hurdle during each Trailing Four Quarter Period (which will apply only to the portion of the Incentive Fee based on income) and each Annual Period (which will apply only to the portion of the Incentive Fee based on capital gains), as follows:

(i) Incentive Fee Based on Income .

(A) The portion of the Incentive Fee based on income will be calculated separately for each Trailing Four Quarter Period. For each such period, the Advisor will be entitled to receive an Incentive Fee based on the amount by which (1) aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss) during the period less, as applicable (x) the amount, if any, by which net unrealized capital depreciation during the period exceeds net realized capital gains during the period or (y) the amount, if any, equal to the sum of net unrealized capital depreciation during the period plus net realized capital loss during the period exceeds (2) the Hurdle for the period. The amount of the excess of (1) over (2) described in this paragraph (A) for each period shall be referred to as the “Excess Income Amount”.

(B) The portion of the Incentive Fee based on income for each period will equal 50% of the period’s Excess Income Amount, until the cumulative Incentive Fee payments for the period equals 20% of the aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss) for the period less, as applicable (x) the amount, if any, by which net unrealized capital depreciation during the period exceeds net realized capital gains during the period or (y) the amount, if any, equal to the sum of net unrealized capital depreciation during the period plus net realized capital loss during the period. Thereafter, the portion of the Incentive Fee based on income for the period will equal an amount such that the cumulative Incentive Fee payments to the Advisor during the period based on income equals 20% of the period’s Excess Income Amount. The portion of the Incentive Fee based on income will be paid on a quarterly basis during each Trailing Four Quarter Period and will be reduced for each quarter in a period (other than the first quarter of each period) by the amount of the Incentive Fee based on income paid in respect of each earlier quarter in the respective period.

(ii) Incentive Fee Based on Capital Gains .

(A) The portion of the Incentive Fee based on capital gains will be calculated separately for each Annual Period. For each such period, the Advisor will be entitled to receive an Incentive Fee based on the amount by which (1) the BDC’s net realized capital gains occurring during the period, if any, exceeds (2) the sum of (x) its unrealized capital depreciation, if any, occurring during the period and (y) the amount, if any, by which the Hurdle for the period exceeds the amount of income used in determination of the portion of the Incentive Fee based on income for the period. The amount of the excess of (1) over (2) described in this paragraph (A) shall be referred to as the “Excess Gain Amount”.

6

(B) The portion of the Incentive Fee based on capital gains for each period will equal 50% of the period’s Excess Gain Amount, until such payments equal 20% of the BDC’s net realized capital gains occurring during the period, if any, less the BDC’s unrealized capital depreciation, if any, occurring during the period. Thereafter, the portion of the Incentive Fee based on capital gains for the period will equal an amount such that the portion of the Incentive Fee payments to the Advisor based on capital gains for the period will equal 20% of the period’s Excess Gain Amount. The portion of the Incentive Fee based on capital gains will be calculated and paid on an annual basis for each Annual Period.

(iii) In calculating the portion of the Incentive Fee based on capital gains payable for any period, the BDC’s investments shall be accounted for on a security-by-security basis. In addition, the portion of the Incentive Fee based on capital gains will be determined using the “period-to-period” method pursuant to which the portion of the Incentive Fee based on capital gains for any period will be based on realized capital gains for the period reduced by realized capital losses and unrealized capital depreciation for the period.

(iv) The calculation of the Incentive Fee described above in this Section 8(d) is illustrated in the examples attached to this Agreement in Annex A. In the event of a conflict between the language above and the examples, the examples shall prevail.

(v) Notwithstanding anything else set forth herein, the Incentive Fee shall not include any amounts of capital gain that would violate Section 205(b)(3) of the Advisers Act as interpreted from time to time by the SEC or its staff.

(e) For purposes of Section 8(d), the following terms shall have the meanings ascribed to them below:

(i) “Annual Period” means the period beginning on July 1 of each calendar year and ending on June 30 of the next calendar year;

(ii) “Hurdle” for any period means the product of 2% times the sum of the net asset values of the BDC attributable to its common shares as of the beginning of each calendar quarter during the respective period calculated after giving effect to any distributions paid in respect of the BDC’s common shares during that period; and

(iii) “Trailing Four Quarter Period” means the four quarter period ending on the last day of each subsequent calendar quarter.

9. Compensation of the Advisor Following the Second Anniversary of this Agreement .

(a) Following the second anniversary of this Agreement, the provisions of this Section 9 shall apply with respect to the compensation of the Advisor.

(b) The Advisor, for its services to the BDC, will be entitled to receive a Management Fee from the BDC. The Management Fee will be calculated at an annual rate of 1.75% of total assets, excluding cash. The Management Fee will be paid quarterly in arrears based on the asset valuation as of the end of the prior quarter and will be prorated for any period of less than a quarter.

(c) For purposes of this Agreement, the assets and net assets of the BDC shall be calculated pursuant to the procedures adopted by resolutions of the Directors of the BDC for calculating the value of the BDC’s assets or delegating such calculations to third parties.

(d) The Advisor will be entitled to receive the Incentive Fee during each calendar quarter (which will apply only to the portion of the Incentive Fee based on income) and each Annual Period (which will apply only to the portion of the Incentive Fee based on capital gains), as follows:

(i) Incentive Fee Based on Income .

(A) The portion of the Incentive Fee based on income other than capital gains will be calculated separately for each calendar quarter and will be paid on a quarterly basis. The BDC will pay the Advisor the portion of the Incentive Fee based on income for each period as follows:

(B) The calculations described above in sub-paragraph (A) will be appropriately pro rated for any period of less than a quarter and adjusted for the net proceeds from any common stock issuances and the cost of any common stock repurchases during such quarter. The payment of any such

8

Incentive Fee based on income otherwise earned by the Advisor shall be deferred if, for the most recent four full calendar quarter period ending on or prior to the date such payment is to be made, the Annualized Rate of Return is less than 7.0% of the BDC’s net assets attributable to common stock at the beginning of such four quarter period as adjusted for the net proceeds from any common stock issuances and the cost of any common stock repurchases during such four full calendar quarter period, with any deferred Incentive Fees to be carried over for payment in subsequent quarterly calculation periods to the extent such payment can then be made in accordance with this Agreement.

(ii) Incentive Fee Based on Capital Gains .

(A) The portion of the Incentive Fee based on capital gains will be calculated separately for each Annual Period. The Advisor will be entitled to receive an Incentive Fee based on capital gains for each Annual Period in an amount equal to 20% of the amount by which (1) the BDC’s net realized capital gains occurring during the period, if any, exceeds (2) its unrealized capital depreciation, if any, occurring during the period.

(B) In calculating the portion of the Incentive Fee based on capital gains payable for any period, the BDC’s investments shall be accounted for on a security-by-security basis. In addition, the portion of the Incentive Fee based on capital gains will be determined using the “period-to-period” method pursuant to which the portion of the Incentive Fee based on capital gains for any period will be based on realized capital gains for the period reduced by realized capital losses for the period and unrealized capital depreciation for the period.

(iii) The calculation of the Incentive Fee described above in this Section 9(d) is illustrated in the examples attached to this Agreement in Annex B. In the event of a conflict between the language above and the examples, the examples shall prevail.

(iv) Notwithstanding anything else set forth herein, the Incentive Fee shall not include any amounts of capital gain that would violate Section 205(b)(3) of the Advisers Act as interpreted from time to time by the SEC or its staff.

(e) For purposes of Section 9(d), the following terms shall have the meanings ascribed to them below:

(i) “Annual Period” means the period beginning on July 1 of each calendar year, including the calendar year prior to the year in which this Section 9 takes effect, and ending on June 30 of the next calendar year;

(ii) “Annualized Rate of Return” is computed by reference to the sum of (i) the aggregate distributions to the BDC’s common stockholders for the period in question and (ii) the change in the BDC’s net assets attributable to common stock (before taking into account any Incentive Fees otherwise payable during such period);

9

(iii) “net assets attributable to common stock” means the BDC’s total assets less indebtedness and preferred stock; and

(iv) “Pre-Incentive Fee Net Investment Income” means net investment income (as determined in accordance with United States generally accepted accounting principles) accrued by the BDC during the calendar quarter excluding any accruals for or payments in respect of the Incentive Fee.

10. Indemnity . (a) The BDC may, in the discretion of the Board of Directors of the BDC, indemnify the Advisor, and each of the Advisor’s directors, officers, employees, agents, associates and controlling persons and the directors, partners, members, officers, employees and agents thereof (including any individual who serves at the Advisor’s request as director, officer, partner, member or the like of another entity) (each such person being an “Indemnitee”) against any liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees (all as provided in accordance with applicable state law) reasonably incurred by such Indemnitee in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or investigative body in which such Indemnitee may be or may have been involved as a party or otherwise or with which such Indemnitee may be or may have been threatened, while acting in any capacity set forth herein or thereafter by reason of such Indemnitee having acted in any such capacity, except with respect to any matter as to which such Indemnitee shall have been adjudicated not to have acted in good faith in the reasonable belief that such Indemnitee’s action was in the best interest of the BDC and furthermore, in the case of any criminal proceeding, so long as such Indemnitee had no reasonable cause to believe that the conduct was unlawful; provided, however, that (1) no Indemnitee shall be indemnified hereunder against any liability to the BDC or its shareholders or any expense of such Indemnitee arising by reason of (i) willful misfeasance, (ii) bad faith, (iii) gross negligence or (iv) reckless disregard of the duties involved in the conduct of such Indemnitee’s position (the conduct referred to in such clauses (i) through (iv) being sometimes referred to herein as “disabling conduct”), (2) as to any matter disposed of by settlement or a compromise payment by such Indemnitee, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless there has been a determination that such settlement or compromise is in the best interests of the BDC and that such Indemnitee appears to have acted in good faith in the reasonable belief that such Indemnitee’s action was in the best interest of the BDC and did not involve disabling conduct by such Indemnitee and (3) with respect to any action, suit or other proceeding voluntarily prosecuted by any Indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such Indemnitee was authorized by a majority of the full Board of Directors of the BDC.

(b) The BDC may make advance payments in connection with the expenses of defending any action with respect to which indemnification might be

10

sought hereunder if the BDC receives a written affirmation of the Indemnitee’s good faith belief that the standard of conduct necessary for indemnification has been met and a written undertaking to reimburse the BDC unless it is subsequently determined that such Indemnitee is entitled to such indemnification and if the Directors of the BDC determine that the facts then known to them would not preclude indemnification. In addition, at least one of the following conditions must be met: (A) the Indemnitee shall provide security for such Indemnitee-undertaking, (B) the BDC shall be insured against losses arising by reason of any unlawful advance, or (C) a majority of a quorum consisting of Directors of the BDC who are neither “interested persons” of the BDC (as defined in Section 2(a)(19) of the 1940 Act) nor parties to the proceeding (“Disinterested Non-Party Directors”) or an independent legal counsel in a written opinion, shall determine, based on a review of readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the Indemnitee ultimately will be found entitled to indemnification.

(c) All determinations with respect to the standards for indemnification hereunder shall be made (1) by a final decision on the merits by a court or other body before whom the proceeding was brought that such Indemnitee is not liable or is not liable by reason of disabling conduct, or (2) in the absence of such a decision, by (i) a majority vote of a quorum of the Disinterested Non-Party Directors of the BDC, or (ii) if such a quorum is not obtainable or, even if obtainable, if a majority vote of such quorum so directs, independent legal counsel in a written opinion. All determinations that advance payments in connection with the expense of defending any proceeding shall be authorized and shall be made in accordance with the immediately preceding clause (2) above.

The rights accruing to any Indemnitee under these provisions shall not exclude any other right to which such Indemnitee may be lawfully entitled.

11. Limitation on Liability . (a) The Advisor will not be liable for any error of judgment or mistake of law or for any loss suffered by Advisor or by the BDC in connection with the performance of this Agreement, except a loss resulting from a breach of fiduciary duty with respect to the receipt of compensation for services or a loss resulting from willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or from reckless disregard by it of its duties under this Agreement.

(b) Notwithstanding anything to the contrary contained in this Agreement, the parties hereto acknowledge and agree that, as provided in the Certificate of Incorporation, this Agreement is executed by the Directors and/or officers of the BDC, not individually but as such Directors and/or officers of the BDC, and the obligations hereunder are not binding upon any of the Directors or Shareholders individually but bind only the estate of the BDC.

12. Duration and Termination . This Agreement shall become effective as of the date hereof and, unless sooner terminated with respect to the BDC as provided herein, shall continue in effect for a period of two years. Thereafter, if not terminated, this Agreement shall continue in effect with respect to the BDC for successive periods of

11

12 months, provided such continuance is specifically approved at least annually by both (a) the vote of a majority of the BDC’s Board of Directors or the vote of a majority of the outstanding voting securities of the BDC at the time outstanding and entitled to vote, and (b) by the vote of a majority of the Directors who are not parties to this Agreement or interested persons of any party to this Agreement, cast in person at a meeting called for the purpose of voting on such approval. Notwithstanding the foregoing, this Agreement may be terminated by the BDC at any time, without the payment of any penalty, upon giving the Advisor 60 days’ notice (which notice may be waived by the Advisor), provided that such termination by the BDC shall be directed or approved by the vote of a majority of the Directors of the BDC in office at the time or by the vote of the holders of a majority of the voting securities of the BDC at the time outstanding and entitled to vote, or by the Advisor on 60 days’ written notice (which notice may be waived by the BDC). This Agreement will also immediately terminate in the event of its assignment. (As used in this Agreement, the terms “majority of the outstanding voting securities,” “interested person” and “assignment” shall have the same meanings of such terms in the 1940 Act.) If this Agreement is terminated pursuant to this Section, the BDC shall pay the Advisor a pro rated portion of the Management Fee and the Incentive Fee. The Management Fee and the Incentive Fee due to the Adviser in the event of termination pursuant to this Section will be determined according to the method set forth in the following paragraph.

The BDC will engage at its own expense a firm acceptable to the BDC and the Advisor to determine the maximum reasonable fair value as of the termination date of the BDC’s consolidated assets (assuming each asset is readily marketable among institutional investors without minority discount and with an appropriate control premium for any control positions and ascribing an appropriate net present value to unamortized organizational and offering costs and going concern value). After review of such firm’s work papers by the Advisor and the BDC and resolution of any comments therefrom, such firm will render its report as to valuation, and the BDC will pay to the Advisor or its affiliates any Management Fees or Incentive Fee, as the case may be, payable pursuant to the paragraphs above as if all of the consolidated assets of the BDC had been sold at the values indicated in such report and any net income and gain distributed. Such report will be completed within 90 days after notice of termination is delivered hereto.

13. Notices . Any notice under this Agreement shall be in writing to the other party at such address as the other party may designate from time to time for the receipt of such notice and shall be deemed to be received on the earlier of the date actually received or on the fourth day after the postmark if such notice is mailed first class postage prepaid.

14. Amendment of this Agreement . No provision of this Agreement may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought. Any amendment of this Agreement shall be subject to the 1940 Act.

15. Governing Law . This Agreement shall be governed by and construed in accordance with the laws of the State of New York for contracts to be performed entirely therein without reference to choice of law principles thereof and in accordance with the applicable provisions of the 1940 Act.

12

16. Use of the Name BlackRock . The Advisor has consented to the use by the BDC of the name or identifying word “BlackRock” in the name of the BDC. Such consent is conditioned upon the employment of the Advisor as the investment advisor to the BDC. The name or identifying word “BlackRock” may be used from time to time in other connections and for other purposes by the Advisor and any of its affiliates. The Advisor may require the BDC to cease using “BlackRock” in the name of the BDC if the BDC ceases to employ, for any reason, the Advisor, any successor thereto or any affiliate thereof as investment advisor of the BDC.

17. Miscellaneous . The captions in this Agreement are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect. If any provision of this Agreement shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby. This Agreement shall be binding on, and shall inure to the benefit of the parties hereto and their respective successors.

18. Counterparts . This Agreement may be executed in counterparts by the parties hereto, each of which shall constitute an original counterpart, and all of which, together, shall constitute one Agreement.

13

IN WITNESS WHEREOF, the parties hereto have caused the foregoing instrument to be executed by their duly authorized officers, all as of the day and the year first above written.

Example of Calculation of Income Portion of Incentive Fee Under Section 8 of the Agreement For each trailing four quarters’ period

Formula

The formula for the income portion of the Incentive Fee for any trailing four quarters’ period can be expressed as follows:

Incentive Fee with respect to income —

Annualized rate of return in this context is computed by reference to our net asset value and does not take into account changes in the market price of our common stock.

Assumptions

Alternative 1

Additional Assumptions

Determination of Incentive Fee

Trailing four quarters’ net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains equals $79.5 million, which exceeds the Hurdle amount. Therefore there may be an Incentive Fee payable with respect to income in Quarter 4. The income portion of the Incentive Fee for this quarter equals 50% of the amount by which the trailing four quarters’ net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains exceeds the Hurdle amount, until the cumulative Incentive Fee payments with respect to income equal 20% of the trailing four quarters’ net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains (would occur if such amount for the trailing four quarters represented an annualized return on net assets of 13.33% or higher, which is the case in this example), less any Incentive Fees paid with respect to income in the prior three quarters.

Incentive Fee with respect to income

Conclusion

The Incentive Fee payable with respect to income for this trailing four quarters’ period equals $2.4 million.

Examples of Calculation of Capital Gains Portion of Incentive Fee

For each Annual Period beginning on the first day of the calendar quarter in which this Agreement is in place and ending on the day prior to the first anniversary of such date

Formula

The formula for the capital gains portion of the Incentive Fee for each Annual Period can be expressed as follows:

Incentive Fee with respect to capital gains = 50% x (net realized capital gains to the extent in excess of gross unrealized capital depreciation, but only to the extent that such net realized capital gains, when added to net investment income, exceed the Hurdle amount), up to a limit of 20% x net realized capital gains to the extent in excess of gross unrealized capital depreciation

The following Alternative 1 and Alternative 2 assume that with respect to each year, the trailing four quarters’ net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains exceeds the hurdle amount.

Alternative 1

Assumptions

The capital gains portion of the Incentive Fee, if any, would be:

Alternative 2

Assumptions

The capital gains portion of the Incentive Fee, if any, would be:

A-3

With respect to each year, if the trailing four quarters’ net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains did not exceed the hurdle amount, the capital gains portion of the Incentive Fee could be reduced because no Incentive Fee is payable unless the sum of (1) the amount of net investment income used in the determination of the Incentive Fee, if any, based on income and (2) the amount of net realized capital gains in excess of unrealized capital depreciation used in the determination of the Incentive Fee, if any, based on capital gains exceeds the hurdle amount. The following Alternative 3 and Alternative 4 illustrate the calculation of the capital gains portion of the Incentive Fee when the hurdle amount is exceeded only after capital gains are taken into account.

Alternative 3

Assumptions

Determination of Incentive Fee

Net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains equals $38.0 million, which does not exceed the Hurdle amount. Therefore there is no Incentive Fee payable with respect to income.

However, Year 1 net realized capital gains to the extent in excess of gross unrealized capital depreciation of $8.0 million, when added to net income of $38.0 million, results in a total of $46.0 million, which exceeds the Hurdle amount. Therefore there is an Incentive Fee payable with respect to capital gains in Year 1.

Incentive Fee with respect to capital gains = 50% x (net realized capital gains to the extent in excess of gross unrealized capital depreciation, but only to the extent that such net realized capital gains, when added to net investment income, exceed the Hurdle amount), up to a limit of 20% x net realized capital gains to the extent in excess of gross unrealized capital depreciation

= 50% x ($46.0 million – $40.0 million), up to a limit of 20% x $8.0 million

= 50% x $6.0 million, up to a limit of $1.6 million

= $1.6 million

Conclusion

The Incentive Fee payable with respect to capital gains for Year 1 equals $1.6 million.

Alternative 4

Assumptions

Determination of Incentive Fee

Net investment income less the excess (if any) of trailing four quarters’ net unrealized capital depreciation over trailing four quarters’ net realized capital gains equals $38.0 million, which does not exceed the Hurdle amount. Therefore there is no Incentive Fee payable with respect to income.

A-4

However, Year 1 net realized capital gains to the extent in excess of gross unrealized capital depreciation of $3.0 million, when added to net investment income of $38.0 million, results in a total of $41.0 million, which exceeds the Hurdle amount. Therefore there is an Incentive Fee payable with respect to capital gains in Year 1.

Incentive Fee with respect to capital gains = 50% x (net realized capital gains to the extent in excess of gross unrealized capital depreciation, but only to the extent that such net realized capital gains, when added to net investment income, exceed the Hurdle amount), up to a limit of 20% x net realized capital gains to the extent in excess of gross unrealized capital depreciation

= 50% x ($41.0 million – $40.0 million), up to a limit of 20% x $3.0 million

= 50% x $1.0 million, up to a limit of $0.6 million

= $0.5 million

Conclusion

The Incentive Fee payable with respect to capital gains for Year 1 equals $0.5 million.

Annex B

Examples of Fee Calculation Under Section 9 of the Agreement

Example 1—Incentive Fee Based on Income(1)

Formula

The formula for the portion of the Incentive Fee based on income for any quarter can be expressed as follows:

Incentive Fee with respect to Pre-Incentive Fee Net Investment Income —

Notwithstanding the foregoing, if the Annualized Rate of Return for the most recent four full calendar quarter period ending on or prior to the date such payment is to be made payment is less than 7.0% of the BDC’s net assets attributable to common stock at the beginning of such four quarter period, adjusted for the net proceeds from any common stock issuances and the cost of any common stock repurchases during the period, the payment of such Incentive Fee will be deferred until the earliest quarter such four full calendar quarter Annualized Rate of Return requirement is satisfied. “Annualized Rate of Return” in this context is computed by reference to the sum of (i) the aggregate distributions the BDC’s common stockholders during the period and (ii) the change in the BDC’s net asset value attributable to common stock prior to calculation of any income or capital gain Incentive Fees during the period and does not take into account changes in the market price of the BDC’s common stock.

Assumptions

Alternative 1

Additional Assumptions

Conclusion

Pre-Incentive Fee Net Investment Income does not exceed the Hurdle rate, therefore there is no Incentive Fee based on income.

Alternative 2

Determination of Incentive Fee

During most recently completed quarter:

Pre-Incentive Fee Net Investment Income for the quarter exceeds the Hurdle rate, therefore there is an Incentive Fee based on income payable for the quarter.

During four quarter period ending with most recently completed quarter:

Conclusion

Although an Incentive Fee is payable for such quarter, because the Annualized Rate of Return over the four quarter period is less than 7.00%, the payment is deferred until the first quarter for which the Annualized Rate of Return over the four quarter period including such subsequent quarter equals or exceeds 7.00%.

If, upon any liquidation, dissolution or winding up of the Corporation, the assets of the Corporation, or proceeds thereof, distributable among the holders of the shares of the Preferred Shares shall be insufficient to pay in full the preferential amount aforesaid, then such assets, or the proceeds thereof, shall be distributed among such holders ratably in accordance with the respective amounts which would be payable on such shares if all amounts payable thereon were paid in full. For the purposes of this paragraph (d), the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation or a consolidation or merger of the Corporation with one or more corporations shall not be deemed to be a dissolution, liquidation or winding up, voluntary or involuntary.

ARTICLE V

Section 5.1 In-Kind Distributions . Section 4.2(c) notwithstanding, the Corporation shall not make a distribution in kind of any securities to any holder of the shares of the Corporation in connection with a Liquidation, if such distribution would in the reasonable judgment of such holder cause such holder to be in violation of any law applicable to such holder (“ERISA Shareholder”); provided that the ERISA Shareholder shall notify the Corporation to such effect not less than five days prior to such distribution. In the event an ERISA Shareholder notifies the Corporation as provided in the immediately preceding sentence, the Corporation shall use its reasonable best efforts to cause the securities or other assets otherwise distributable to the ERISA Shareholder (the “Subject Securities”) to be sold to a third party, who may be another holder of shares in the Corporation, for the best consideration available under the circumstances, as determined by the Board of Directors in its reasonable discretion, and, upon consummation of any such sale, the cash proceeds from such sale shall be distributed to the ERISA Shareholder. In the event such a sale cannot be consummated for the best consideration available under the circumstances and within a reasonable period of time following the time of the proposed distribution (in no case to exceed two years), the obligation of the Corporation to the ERISA Shareholder shall be extinguished by establishing, with an escrow agent designated by the ERISA Shareholder, an escrow account for the benefit of the ERISA Shareholder into which the Subject Securities shall be deposited, which account shall be liquidated at such time as a sale can be accomplished on the terms set forth above; provided that from and after the time of such deposit such Subject Securities shall be deemed for all purposes of this Certificate of Incorporation to have been distributed to the ERISA Shareholder and any income arising from the Subject Securities shall be deposited in such account for the benefit of the ERISA Shareholder.

Any such determination shall be conclusive and binding for all purposes of this Section.

(f) “Public Market Event” shall mean an initial public offering of the Corporation’s Common Shares registered under the Securities Act and the listing of such Common Shares on a national securities exchange.

ARTICLE XIV

Such notice will also specify the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting. No business (including without limitation nominations for the election of directors) may be transacted at an annual or special meeting of stockholders, other than business that is either (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof), (ii) otherwise properly brought before the meeting by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (iii) in the case of an annual meeting, otherwise properly brought before the meeting by any stockholder of the BDC, whether such proposal is included in the BDC’s proxy statement or a proxy statement prepared by one or more stockholders, (A) who is a stockholder of record on the date notice is given as provided for in this Article I Section 1.3 and on the record date for the determination of stockholders entitled to notice of and to vote at such annual meeting and (B) who complies with the notice procedures set forth in this Article I Section 1.3 or, with respect to the election of Directors, set forth in Section 2.2 of Article II.

(a) In addition to any other applicable requirements, for business to be properly brought before a meeting by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary of the BDC.

(i) To be timely, a stockholder’s notice to the Secretary must be delivered to or mailed and received at the principal executive offices of the BDC (A) in the case of an annual meeting, not less than ninety (90) days nor more than one hundred twenty (120) days prior to the anniversary date of the immediately preceding annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within thirty (30) days before or after such anniversary date, notice by the stockholder in order to be timely must be so received not later than the close of business on the tenth (10th) day following the day on which such notice of the date of the meeting was mailed or such public disclosure of the date of the meeting was made, whichever first occurs; and (B) in the case of a special meeting of stockholders called for the purpose of electing directors, not later than the close of business on the fifth (5th) day following the day on which notice of the date of the special meeting was mailed or public disclosure of the date of the special meeting was made, whichever first occurs.

(ii) Except for notices regarding nominations for the election of directors, which notices shall be prepared in accordance with Article II Section 2.2(c)(ii), to be in proper written form, a stockholder’s notice to the Secretary must set forth as to each matter such stockholder proposes to bring before the meeting (A) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, (B) the name and record address of such stockholder, (C) the class or series and number of shares of the BDC which are owned beneficially or of record by such stockholder, (D) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business and (E) a representation that such stockholder intends to appear in person or by proxy at the meeting to bring such business before the meeting.

(b) No business shall be conducted at a meeting of stockholders except business brought before the meeting in accordance with the procedures set forth in this Article I Section 1.3 or Article II Section 2.2, as the case may be; provided, however, that, once business has been properly brought before the meeting in accordance with such procedures, nothing in this Article I Section 1.3 shall be deemed to preclude discussion by any stockholder of any such business. If the chairman of a meeting determines that business was not properly brought before the meeting in accordance with the foregoing procedures, the chairman of the meeting shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted.

1.4 Chairman . The Chairman shall act as chairman at all meetings of the stockholders; in the Chairman’s absence, the Director or Directors present at each meeting may elect a temporary chairman for the meeting, who may be one of themselves.

2

1.5 Proxies; Voting . Stockholders may vote either in person or by duly executed proxy and each full share represented at the meeting shall have one vote, all as provided in Article IV of the Certificate.

1.6 Inspectors of Election . In advance of any meeting of stockholders, the Directors may appoint Inspectors of Election to act at the meeting or any adjournment thereof. If Inspectors of Election are not so appointed, the Chairman of any meeting of stockholders may, and on the request of any stockholder or stockholder proxy shall, appoint Inspectors of Election of the meeting. The number of Inspectors of Election shall be one unless the Directors shall determine to appoint three. In case any person appointed as Inspector of Election fails to appear or fails or refuses to act, the vacancy may be filled by appointment made by the Directors in advance of the convening of the meeting or at the meeting by the person acting as chairman. The Inspectors of Election shall determine the number of shares of stock of the BDC (the “Shares”) outstanding, the Shares represented at the meeting, the existence of a quorum, the authenticity, validity and effect of proxies, shall receive votes, ballots or consents, shall hear and determine all challenges and questions in any way arising in connection with the right to vote, shall count and tabulate all votes or consents, determine the results, and do such other acts as may be proper to conduct the election or vote with fairness to all stockholders. If there are three Inspectors of Election, the decision, act or certificate of a majority is effective in all respects as the decision, act or certificate of all. On request of the Chairman of the meeting, or of any stockholder or stockholder proxy, the Inspectors of Election shall make a report in writing of any challenge or question or matter determined by them and shall execute a certificate of any facts found by them.

1.7 Records at Stockholder Meetings . At each meeting of the stockholders, there shall be made available for inspection at a convenient time and place during normal business hours, if requested by stockholders, the minutes of the last previous Annual or Special Meeting of stockholders of the BDC and a list of the stockholders of the BDC, as of the record date of the meeting or the date of closing of transfer books, as the case may be. Such list of stockholders shall contain the name and the address of each stockholder in alphabetical order and the number of Shares owned by such stockholder. Stockholders shall have such other rights and procedures of inspection of the books and records of the BDC as are granted to stockholders of a Delaware business corporation.

1.8 Quorum at Stockholder Meetings . The holders of a majority of the outstanding shares of capital stock entitled to vote at the meeting of stockholders, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by the Delaware General Corporation Law or the Certificate. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum. If a quorum is not present, the chairman of the meeting or the holders of a majority of the shares present in person or represented by proxy at the meeting, and entitled to vote at the meeting, may adjourn the meeting to another time and/or place. When a specified item of business requires a vote by the holders of a class or series of shares of capital stock (if the BDC shall then have outstanding shares of more than one class or series) voting as a class or series, the holders of a majority of the shares of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business, except as otherwise provided by the Delaware General Corporation Law or by the Certificate. Notwithstanding the foregoing, if there is no election contest and a majority of the outstanding shares of capital stock entitled to

3

vote at the meeting are not present in person or by proxy, the holders of one–third of such shares (and one–third of the shares of any class or series) shall constitute a quorum to the extent permitted by applicable law.

STOCK TRANSFERS

6.1 Certificates . The shares of stock of the BDC shall be represented by a certificate, unless and until the Board of Directors adopts a resolution permitting shares to be uncertificated. Notwithstanding the adoption of any such resolution providing for uncertificated shares, every holder of stock of the BDC theretofore represented by certificates and, upon request, every holder of uncertificated shares, shall be entitled to a certificate or certificates which shall represent and certify the number of shares of each class of stock held by him, her or it in the BDC. Each certificate shall be signed by the Chairman or a vice president and countersigned by the secretary or an assistant secretary or the treasurer or an assistant treasurer and may be sealed with the seal, if any, of the BDC. The signatures may be either manual or facsimile. Certificates shall be consecutively numbered; and if the BDC shall, from time to time, issue several classes of shares, each class may have its own number series. A certificate is valid and may be issued whether or not an officer who signed it is still an officer when it is issued. Each certificate representing shares which are restricted as to their transferability or voting powers, which are preferred or limited as to their dividends or as to their allocable portion of the assets upon liquidation or which are redeemable at the option of the BDC, shall have a statement of such restriction, limitation, preference or redemption provision, or a summary thereof, plainly stated on the certificate. In lieu of such statement or summary, the BDC may set forth upon the face or back of the certificate a statement that the BDC will furnish to any stockholder, upon request and without charge, a full statement of such information.

6.2 Transfer Agents, Registrars and the Like . The Directors shall have authority to employ and compensate such transfer agents and registrars with respect to the Shares of the BDC as the Directors shall deem necessary or desirable. In addition, the Directors shall have power to employ and compensate such dividend disbursing agents, warrant agents and agents for the reinvestment of dividends as they shall deem necessary or desirable. Any of such agents shall have such power and authority as is delegated to any of them by the Directors.

6.3 Transfer of Shares . Stock of the BDC shall be transferable in the manner prescribed by applicable law and in these By–Laws. Transfers of stock shall be made on the books of the BDC, and in the case of certificated shares of stock, only by the person named in the certificate or by such person’s attorney lawfully constituted in writing and upon the surrender of the certificate therefor, properly endorsed for transfer and payment of all necessary transfer taxes; or, in the case of uncertificated shares of stock, upon receipt of proper transfer instructions from the registered holder of the shares or by such person’s attorney lawfully constituted in writing, and upon payment of all necessary transfer taxes and compliance with appropriate procedures for transferring shares in uncertificated form; provided, however, that such surrender and endorsement, compliance or payment of taxes shall not be required in any case in which the officers of the BDC shall determine to waive such requirement. With respect to certificated shares of stock, every certificate exchanged, returned or surrendered to the BDC shall be marked “Cancelled,” with the date of cancellation, by the Secretary of the BDC or the transfer agent thereof. No transfer of stock shall be valid as against the BDC for any purpose until it shall have been entered in the stock records of the BDC by an entry showing from and to whom transferred.

6.4 Replacement Certificate . Any officer designated by the Board of Directors may direct a new certificate to be issued in place of any certificate previously issued by the BDC alleged to have been lost, stolen or destroyed upon the making of an affidavit of that fact by the person claiming the certificate to be lost, stolen or destroyed. When authorizing the issuance of a new certificate, an officer designated by the Board of Directors may, in his or her discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or the owner’s legal representative to advertise the same in such manner as he shall require and/or to give bond, with sufficient surety, to the BDC to indemnify it against any loss or claim which may arise as a result of the issuance of a new certificate.

6.5 Closing of Transfer Books or Fixing of Record Date . The Board of Directors may set, in advance, a record date for the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders or determining stockholders entitled to receive payment of any dividend or the allotment of any other rights, or in order to make a determination of stockholders for any other proper purpose. Such date, in any case, shall not be prior to the close of business on the day the record date is fixed and shall be not more than 90 days and, in the case of a meeting of stockholders, not less than ten days, before the date on which the meeting or particular action requiring such determination of stockholders of record is to be held or taken.

In lieu of fixing a record date, the Board of Directors may provide that the stock transfer books shall be closed for a stated period but not longer than 20 days. If the stock transfer books are closed for the purpose of determining stockholders entitled to notice of or to vote at a meeting of stockholders, such books shall be closed for at least ten days before the date of such meeting.

If no record date is fixed and the stock transfer books are not closed for the determination of stockholders, (a) the record date for the determination of stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day on which the notice of meeting is mailed or the 30th day before the meeting, whichever is the closer date to the meeting; and (b) the record date for the determination of stockholders entitled to receive

12

payment of a dividend or an allotment of any other rights shall be the close of business on the day on which the resolution of the directors, declaring the dividend or allotment of rights, is adopted.

When a determination of stockholders entitled to vote at any meeting of stockholders has been made as provided in this section, such determination shall apply to any adjournment thereof, except when (i) the determination has been made through the closing of the transfer books and the stated period of closing has expired or (ii) the meeting is adjourned to a date more than 120 days after the record date fixed for the original meeting, in either of which case a new record date shall be determined as set forth herein.

6.6 Stock Ledger . The BDC shall maintain at its principal office or at the office of its counsel, accountants or transfer agent, an original or duplicate share ledger containing the name and address of each stockholder and the number of shares of each class held by such stockholder.

6.7 Fractional Stock; Issuance of Units . The Board of Directors may issue fractional stock or provide for the issuance of scrip, all on such terms and under such conditions as they may determine. Notwithstanding any other provision of the Certificate of Incorporation or these By–laws, the Board of Directors may issue units consisting of different securities of the BDC. Any security issued in a unit shall have the same characteristics as any identical securities issued by the BDC, except that the Board of Directors may provide that for a specified period securities of the BDC issued in such unit may be transferred on the books of the BDC only in such unit.

6.8 Registered Stockholders . The BDC may deem and treat the holder of record of any Shares as the absolute owner thereof for all purposes and shall not be required to take any notice of any right or claim of right of any other person.

ARTICLE VII

AMENDMENT OF BY–LAWS

7.1 Amendment and Repeal of By–Laws . In accordance with Section 10.1 of the Certificate of Incorporation, the Directors shall have the power to amend or repeal the By–Laws or adopt new By–Laws at any time. Action by the Directors with respect to the By–Laws shall be taken by an affirmative vote of a majority of the Directors. The Directors shall in no event adopt By–Laws which are in conflict with the Certificate, and any apparent inconsistency shall be construed in favor of the related provisions in the Certificate. Stockholders shall have no authority to adopt, amend or repeal By–Laws except to the extent required by law.

ARTICLE VIII

NOTICE

8.1 Notices . Whenever written notice is required by law, the Certificate of Incorporation or these By–Laws (except as set forth in Sections 1.3 and 2.2 herein or as

13

otherwise stated therein or herein), to be given to any director, member of a committee or stockholder, such notice may be given by mail, addressed to such director, member of a committee or stockholder, at such person’s address as it appears on the records of the Corporation, with postage thereon prepaid, and such notice shall be deemed to be given at the time when the same shall be deposited in the United States mail. Written notice may also be given personally or by telegram, telex, cable, facsimile, transmission, email or other electronic means to any address provided to the BDC by the person being notified.

8.2 Waiver of Notices . Whenever any notice is required by applicable law, the Certificate of Incorporation or these By–Laws (except as stated therein or herein), to be given to any director, member of a committee or stockholder, a waiver thereof in writing, signed by the person or persons entitled to notice, whether before or after the time stated therein, shall be deemed equivalent thereto. Attendance of a person at a meeting, present in person or represented by proxy, shall constitute a waiver of notice of such meeting, except where the person attends the meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any annual or special meeting of stockholders or any regular or special meeting of the directors or members of a committee of directors need be specified in any written waiver of notice unless so required by law, the Certificate of Incorporation or these By–Laws.
