3.5.If an Acquired Fund is unable to make delivery pursuant to paragraph 3.3 hereof to a Custodian of an

Acquiring Fund (the "Acquiring Fund Custodian") of any of the assets of an Acquired Fund for the reason that any of such assets have not yet been delivered to it by an Acquired Fund's broker, dealer or other counterparty, then, in lieu of such delivery, an Acquired Fund shall deliver, with respect to said assets, executed copies of an agreement of assignment and due bills executed on behalf of said broker, dealer or other counterparty, together with such other documents as may be required by an Acquiring Fund or an Acquiring Fund Custodian, including brokers' confirmation slips.

6.7.6.An Acquiring Fund's holding periods with respect to the assets of an Acquired Fund that an Acquiring Fund acquires in the Reorganization will include the respective periods for which those assets were held by an Acquired Fund (except where investment activities of an Acquiring Fund have the effect of reducing or eliminating a holding period with respect to an asset and except for any assets which may be marked to market for U.S. federal income tax purposes on the termination of an Acquired Fund's taxable year or on which gain was recognized upon the transfer to an Acquiring Fund).

6.7.7.An Acquired Fund's Shareholders will recognize no gain or loss upon receiving Acquiring Fund Shares solely in exchange for Acquired Fund shares.

6.7.8.The basis of the Acquiring Fund Shares received by an Acquired Fund's Shareholder in the transaction will be the same as the basis of Acquired Fund shares surrendered by an Acquired Fund's Shareholder in exchange therefor.

6.7.9.An Acquired Fund Shareholder's holding period for the Acquiring Fund Shares received by the Acquired Fund Shareholder in the transaction will include the holding period during which the Acquired Fund Shareholder held Acquired Fund shares surrendered in exchange therefor, provided that the Acquired Fund Shareholder held such shares as a capital asset on the date of the Reorganization.

6.7.10.Pursuant to Section 381 of the Code and Section 1.381(a)-1 of the United States Treasury regulations, an Acquiring Fund will succeed to and take into account the items of an Acquired Fund described in Section 381(c) of the Code, subject to the provisions and limitations specified in Sections 381, 382, 383, and

384of the Code and the United States Treasury regulations promulgated thereunder.
