</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Maryland law permits a Maryland corporation to include in its articles of incorporation a
provision limiting the liability of its directors and officers to the corporation and its
stockholders for money damages except for liability resulting from (a)&nbsp;actual receipt of an
improper benefit or profit in money, property or services or (b)&nbsp;active and deliberate dishonesty
established by a final judgment as being material to the cause of action. Our articles of
incorporation contain such a provision that eliminates directors&#146; and officers&#146; liability to the
maximum extent permitted by Maryland law, subject to the requirements of the Investment Company Act
of 1940, as amended (the &#147;1940 Act&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our articles of incorporation require us, to the maximum extent permitted by Maryland law and
subject to the requirements of the 1940 Act, to indemnify any present or former director or officer
or any individual who, while a director or officer and at our request, serves or has served another
corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan
or other enterprise as a director, officer, partner or trustee, from and against any claim or
liability to which such person may become subject or which such person may incur by reason of his
or her service in any such capacity, except with respect to any matter as to which such person
shall have been finally adjudicated in any proceeding not to have acted in good faith in the
reasonable belief that his or her action was in our best interest or to be liable to us or our
stockholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of such person&#146;s office.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our bylaws obligate us, to the maximum extent permitted by Maryland law and subject to the
requirements of the 1940 Act, to indemnify any present or former director or officer or any
individual who, while a director or officer and at our request, serves or has served another
corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan
or other enterprise as a director, officer, partner or trustee and who is made, or threatened to be
made, a party to a proceeding by reason of his or her service in any such capacity from and against
any claim or liability to which that person may become subject or which that person may incur by
reason of his or her service in any such capacity, except with respect to any matter as to which
such person shall have been finally adjudicated in any proceeding not to have acted in good faith
in the reasonable belief that his or her action was in our best interest or to be liable to us or
our stockholders by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such person&#146;s office. Our bylaws also require
that, to the maximum extent permitted by Maryland law, we may pay certain expenses incurred by any
such indemnified person in advance of the final disposition of a proceeding upon receipt of an
undertaking by or on behalf of such indemnified person to repay amounts we have so paid if it is
ultimately determined that indemnification of such expenses is not authorized under our bylaws.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Maryland law requires a corporation (unless its articles of incorporation provide otherwise,
which our articles of incorporation do not) to indemnify a director or officer who has been
successful in the defense of any proceeding to which he or she is made, or threatened to be made, a
party by reason of his or her service in that capacity. Maryland law permits a corporation to
indemnify its present and former directors and officers, among others, against judgments,
penalties, fines, settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made, or threatened to be made, a party by reason of his or her
service in those or other capacities unless it is established that (a)&nbsp;the act or omission of the
director or officer was material to the matter giving rise to the proceeding and (1)&nbsp;was committed
in bad faith or (2)&nbsp;was the result of active and deliberate dishonesty, (b)&nbsp;the director or officer
actually received an improper personal benefit in money, property or services or (c)&nbsp;in the case of
any criminal proceeding, the director or officer had reasonable cause to believe that the act or
omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an
adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on
the basis that a personal benefit was improperly received, unless in either case a court orders
indemnification, and then only for expenses. In addition, Maryland law permits a corporation to
advance reasonable expenses to a director or officer upon the corporation&#146;s receipt of (a)&nbsp;a
written affirmation by the director or officer of his or her good faith belief that he or she has
met the standard of conduct necessary for indemnification by the corporation and (b)&nbsp;a written
undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the
corporation if it is ultimately determined that the standard of conduct was not met.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, we have entered into Indemnity Agreements with our directors and executive
officers. The form of Indemnity Agreement entered into with each director and officer was
previously filed with the Commission as Exhibit (k)(13) to our Registration Statement on Form N-2
(Reg. No.&nbsp;333-142879). The Indemnity Agreements generally provide that we will, to the extent
specified in the agreements and to the fullest extent permitted by the

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">1940 Act and Maryland law as in effect on the day the agreement is executed , indemnify and
advance expenses to each indemnitee that is, or is threatened to be made, a party to or a witness
in any civil, criminal or administrative proceeding. We will indemnify the indemnitee against all
expenses, judgments, fines, penalties and amounts paid in settlement actually and reasonably
incurred in connection with any such proceeding unless it is established that (i)&nbsp;the act or
omission of the indemnitee was material to the matter giving rise to the proceeding and (a)&nbsp;was
committed in bad faith or (b)&nbsp;was the result of active and deliberate dishonesty, (ii)&nbsp;the
indemnitee actually received an improper personal benefit, or (iii)&nbsp;in the case of a criminal
proceeding, the indemnitee had reasonable cause to believe his conduct was unlawful. Additionally,
for so long as the we are subject to the 1940 Act, no advancement of expenses will be made until
(i)&nbsp;the indemnitee provides a security for his undertaking, (ii)&nbsp;we are insured against losses
arising by reason of any lawful advances, or (iii)&nbsp;the majority of a quorum of our disinterested
directors, or independent counsel in a written opinion, determine based on a review of readily
available facts that there is reason to believe that the indemnitee ultimately will be found
entitled to indemnification. The Indemnity Agreements also provide that if the indemnification
rights provided for therein are unavailable for any reason, we will pay, in the first instance, the
entire amount incurred by the indemnitee in connection with any covered proceeding and waive and
relinquish any right of contribution we may have against the indemnitee. The rights provided by
the Indemnity Agreements are in addition to any other rights to indemnification or advancement of
expenses to which the indemnitee may be entitled under applicable law, our articles of
incorporation, our bylaws, any agreement, a vote of stockholders or a resolution of directors, or
otherwise. No amendment or repeal of the Indemnity Agreements will limit or restrict any right of
the indemnitee in respect of any action taken or omitted by the indemnitee prior to such amendment
or repeal. The Indemnity Agreements will terminate upon the later of (i)&nbsp;ten years after the date
the indemnitee has ceased to serve as our director or officer, or (ii)&nbsp;one year after the final
termination of any proceeding for which the indemnitee is granted rights of indemnification or
advancement of expenses or which is brought by the indemnitee. The above description of the
Indemnity Agreements is subject to, and is qualified in its entirety by reference to, all the
provisions of the form of Indemnity Agreement, previously filed with the Commission as Exhibit
(k)(13) to our Registration Statement on Form N-2 (Reg. No.&nbsp;333-142879).

against certain liabilities they may incur in their capacity as directors and officers. Under such
policies, the insurer, on our behalf, may also pay amounts for which we have granted
indemnification to the directors or officers.

permitted to directors, officers and controlling persons of the registrant pursuant to the
provisions described under Item&nbsp;6 above, or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is against public policy
as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such
issue.

Item 6. Indemnification of Directors and Officers.
Maryland law permits a Maryland corporation to include in its articles of incorporation a
provision limiting the liability of its directors and officers to the corporation and its
stockholders for money damages except for liability resulting from (a) actual receipt of an
improper benefit or profit in money, property or services or (b) active and deliberate dishonesty
established by a final judgment as being material to the cause of action. Our articles of
incorporation contain such a provision that eliminates directors' and officers' liability to the
maximum extent permitted by Maryland law, subject to the requirements of the Investment Company Act
of 1940, as amended (the "1940 Act").
Our articles of incorporation require us, to the maximum extent permitted by Maryland law and
subject to the requirements of the 1940 Act, to indemnify any present or former director or officer
or any individual who, while a director or officer and at our request, serves or has served another
corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan
or other enterprise as a director, officer, partner or trustee, from and against any claim or
liability to which such person may become subject or which such person may incur by reason of his
or her service in any such capacity, except with respect to any matter as to which such person
shall have been finally adjudicated in any proceeding not to have acted in good faith in the
reasonable belief that his or her action was in our best interest or to be liable to us or our
stockholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of such person's office.
Our bylaws obligate us, to the maximum extent permitted by Maryland law and subject to the
requirements of the 1940 Act, to indemnify any present or former director or officer or any
individual who, while a director or officer and at our request, serves or has served another
corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan
or other enterprise as a director, officer, partner or trustee and who is made, or threatened to be
made, a party to a proceeding by reason of his or her service in any such capacity from and against
any claim or liability to which that person may become subject or which that person may incur by
reason of his or her service in any such capacity, except with respect to any matter as to which
such person shall have been finally adjudicated in any proceeding not to have acted in good faith
in the reasonable belief that his or her action was in our best interest or to be liable to us or
our stockholders by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such person's office. Our bylaws also require
that, to the maximum extent permitted by Maryland law, we may pay certain expenses incurred by any
such indemnified person in advance of the final disposition of a proceeding upon receipt of an
undertaking by or on behalf of such indemnified person to repay amounts we have so paid if it is
ultimately determined that indemnification of such expenses is not authorized under our bylaws.
Maryland law requires a corporation (unless its articles of incorporation provide otherwise,
which our articles of incorporation do not) to indemnify a director or officer who has been
successful in the defense of any proceeding to which he or she is made, or threatened to be made, a
party by reason of his or her service in that capacity. Maryland law permits a corporation to
indemnify its present and former directors and officers, among others, against judgments,
penalties, fines, settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made, or threatened to be made, a party by reason of his or her
service in those or other capacities unless it is established that (a) the act or omission of the
director or officer was material to the matter giving rise to the proceeding and (1) was committed
in bad faith or (2) was the result of active and deliberate dishonesty, (b) the director or officer
actually received an improper personal benefit in money, property or services or (c) in the case of
any criminal proceeding, the director or officer had reasonable cause to believe that the act or
omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an
adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on
the basis that a personal benefit was improperly received, unless in either case a court orders
indemnification, and then only for expenses. In addition, Maryland law permits a corporation to
advance reasonable expenses to a director or officer upon the corporation's receipt of (a) a
written affirmation by the director or officer of his or her good faith belief that he or she has
met the standard of conduct necessary for indemnification by the corporation and (b) a written
undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the
corporation if it is ultimately determined that the standard of conduct was not met.
In addition, we have entered into Indemnity Agreements with our directors and executive
officers. The form of Indemnity Agreement entered into with each director and officer was
previously filed with the Commission as Exhibit (k)(13) to our Registration Statement on Form N-2
(Reg. No. 333-142879). The Indemnity Agreements generally provide that we will, to the extent
specified in the agreements and to the fullest extent permitted by the
2
Table of Contents
1940 Act and Maryland law as in effect on the day the agreement is executed , indemnify and
advance expenses to each indemnitee that is, or is threatened to be made, a party to or a witness
in any civil, criminal or administrative proceeding. We will indemnify the indemnitee against all
expenses, judgments, fines, penalties and amounts paid in settlement actually and reasonably
incurred in connection with any such proceeding unless it is established that (i) the act or
omission of the indemnitee was material to the matter giving rise to the proceeding and (a) was
committed in bad faith or (b) was the result of active and deliberate dishonesty, (ii) the
indemnitee actually received an improper personal benefit, or (iii) in the case of a criminal
proceeding, the indemnitee had reasonable cause to believe his conduct was unlawful. Additionally,
for so long as the we are subject to the 1940 Act, no advancement of expenses will be made until
(i) the indemnitee provides a security for his undertaking, (ii) we are insured against losses
arising by reason of any lawful advances, or (iii) the majority of a quorum of our disinterested
directors, or independent counsel in a written opinion, determine based on a review of readily
available facts that there is reason to believe that the indemnitee ultimately will be found
entitled to indemnification. The Indemnity Agreements also provide that if the indemnification
rights provided for therein are unavailable for any reason, we will pay, in the first instance, the
entire amount incurred by the indemnitee in connection with any covered proceeding and waive and
relinquish any right of contribution we may have against the indemnitee. The rights provided by
the Indemnity Agreements are in addition to any other rights to indemnification or advancement of
expenses to which the indemnitee may be entitled under applicable law, our articles of
incorporation, our bylaws, any agreement, a vote of stockholders or a resolution of directors, or
otherwise. No amendment or repeal of the Indemnity Agreements will limit or restrict any right of
the indemnitee in respect of any action taken or omitted by the indemnitee prior to such amendment
or repeal. The Indemnity Agreements will terminate upon the later of (i) ten years after the date
the indemnitee has ceased to serve as our director or officer, or (ii) one year after the final
termination of any proceeding for which the indemnitee is granted rights of indemnification or
advancement of expenses or which is brought by the indemnitee. The above description of the
Indemnity Agreements is subject to, and is qualified in its entirety by reference to, all the
provisions of the form of Indemnity Agreement, previously filed with the Commission as Exhibit
(k)(13) to our Registration Statement on Form N-2 (Reg. No. 333-142879).
We have obtained primary and excess insurance policies insuring our directors and officers
against certain liabilities they may incur in their capacity as directors and officers. Under such
policies, the insurer, on our behalf, may also pay amounts for which we have granted
indemnification to the directors or officers.
Reference is made to Item 9 for our undertakings with respect to indemnification for
liabilities arising under the Securities Act.

Item 9. Undertakings.
(a) The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of
1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the information set
forth in the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus filed with
the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to such
information in the registration statement;
Provided, however,
that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if
the registration statement is on Form S-8 and the information required to be included in a
post-effective amendment by those paragraphs is contained in reports filed with or furnished
to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the registration
statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933,
each such post-effective amendment shall be deemed to be a new registration statement relating
to the securities offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the offering.
(b) The registrant hereby undertakes that, for purposes of determining any liability under the
Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in this registration statement
4
Table of Contents
shall be deemed to be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial bona fide offering
thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the registrant pursuant to the
provisions described under Item 6 above, or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is against public policy
as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such
issue.
