ii. Trading of the shares of Stock on the listing exchange or the primary market center is suspended for any reason; or

iii. MSI cannot effect a purchase of shares of Stock due to legal, regulatory or contractual restrictions applicable to it or the Manager or the Funds (including without limitation, Regulation M, Rule 10b-5 or Rule 10b-18).

iii. The Manager agrees not to enter into or alter any corresponding or hedging transaction with respect to the Stock while this Purchase Plan remains in effect.

iv. If applicable, the Manager agrees to provide MSI with all necessary information regarding the Fund’s previous purchases, as may be required for MSI to calculate the Fund’s volume limitations under Rule 10b-18.

viii. The Manager acknowledges and agrees that the Purchase Plan is a “securities contract,” as such term is defined in Section 741(7) of Title 11 of the United States Code, as it may be amended (the “Bankruptcy Code”), entitled to all of the protections given such contracts under the Bankruptcy Code.

ix. This Purchase Plan constitutes the Manager and the Fund’s legal, valid and binding obligation enforceable against the Manager and the Funds in accordance with its terms.  There is no litigation, arbitration or other proceeding pending, or to the Manager’s knowledge threatened, that would prevent or interfere with the Manager or the Fund’s purchase of Stock under this Purchase Plan.

This indemnification will survive the termination of this Purchase Plan.

ii. Notwithstanding any other provision herein, neither MSI, the Manager or the Funds will be liable for:

(1) Special, indirect, punitive, exemplary, or consequential damages, or incidental losses or damages or any kind, even if advised of the possibility of such losses or damages or if such losses or damages could have been reasonably foreseen.

(2) Any failure to perform or for any delay in performance that results from a cause or circumstance that is beyond its reasonable control, including but not limited to failure of electronic or mechanical equipment, strikes, failure of common carrier or utility systems, severe weather, market disruptions or other causes commonly known as “acts of God”.

iii. The Manager acknowledges and agrees that MSI has not provided the Manager with any tax, accounting or legal advice with respect to this Purchase Plan, including whether the Manager or the Funds would be entitled to any of the affirmative defenses under Rule 10b5-1 or be provided a “safe harbor” from liability for manipulation under Section 9(a)(2) of the Exchange Act and Rule 10b-5 under the Exchange Act.
