SECTION 3. REDEMPTIONS AT THE OPTION OF THE TRUST

The Trust shall have the right at its option and at any time to redeem Shares of any Shareholder at the net asset value thereof as described in Section 1 of this Article VI if: (i) the value of such shares in the account of such Shareholder is less than minimum investment amounts applicable to that account as set forth in the Trust’s then-current registration statement under the 1940 Act; (ii) the Shareholder fails to furnish the Trust with the holder’s correct taxpayer identification number or social security number and to make such certifications with respect thereto as the Trust may require; (iii) such Shareholder fails to meet or maintain the qualifications for ownership of a particular series or class; or (iv) the Trustees determine, in their sole discretion, that the ownership of Shares by one or more Shareholders is not in the best interests of the remaining Shareholders of the Trust or of the applicable series or class. Provided, however, that any such redemptions shall be subject to such further terms and conditions as the Trustees may from time to time adopt.

IN WITNESS WHEREOF, a majority of the Trustees do hereto set their hands as of the date first referenced above.
