(b) The Underwriter severally agrees to indemnify and hold harmless the Fund and the Adviser, their respective directors, each of the Fund's officers who signed the Registration Statement, and each person, if any, who controls the Fund or the Adviser within the meaning of Section 15 of the 1933 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment or supplement thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Fund by the Underwriter expressly for use in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto). 15 (c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

Notwithstanding provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay in respect of such losses, liabilities, claims, damages and expenses. For purposes of this Section, each person, if any, who controls the Underwriter within the meaning of Section 15, of the 1933 Act shall have the same rights to contribution as the Underwriter, and each director of the Fund, each officer of the Fund who signed the Registration Statement, and each person, if any, who controls the Fund within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Underwriter, and each director of the Fund, each officer of the Fund who signed the Registration Statement, and each person, if any, who controls the Fund within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Fund.

SECTION 10. Termination of Agreement. (a) The Underwriter, by notice to the Fund, may terminate this Agreement at any time or prior to Closing Time (i) if there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Fund or the Adviser, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis the effect of which is such as to make it, in the Underwriter's 16 judgment, impracticable to market the Shares or enforce contracts for the sale of the Shares, or (iii) if trading in the Common Shares has been suspended by the Commission or if trading generally on either the American Stock Exchange or the New York Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by either of said exchanges or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by Federal or New York authorities.
