Unless the context otherwise requires, with respect to every transaction covered by this Agreement, every reference herein to a Fund shall be deemed to relate solely to the particular Series of that Fund to which such transaction relates. Under no circumstances shall the rights, obligations or remedies with respect to a particular Series constitute a right, obligation or remedy applicable to any other Series.

     12. Term of Agreement. This Agreement shall become effective as of the date first written above and unless sooner terminated as hereinafter provided, shall continue in effect.

     13. Termination.

	(a)		Any party to this Agreement may terminate the Agreement as to that party and without penalty without cause by providing sixty (60) days written notice of termination. This is Agreement is terminable, without penalty, at any time by a Fund.

This provision, however, shall in no way excuse Domini from being liable to a Fund for any and all losses, damages, costs, charges, counsel fees, payments and expenses incurred by a Fund due to the non-performance or delay in performance by Domini of its duties and obligation under this Agreement if such non-performance or delay in performance could have been reasonably prevented by Domini through back-up systems and other procedures commonly employed by other persons in the mutual fund industry who provide services similar to those to be provided by Domini under this Agreement, provided that Domini shall have the right, at all times, to mitigate or cure any losses, including by making adjustments or corrections to any current or former shareholder accounts.

     15. Miscellaneous.

If any provision of this Agreement shall be held or made invalid in whole or in part by a court decision, statute, rule, or otherwise, the remaining provisions of the Agreement shall not be affected thereby. Invalid provisions shall, in accordance with the intent and purpose of this Agreement, be replaced by mutual consent of the parties with such valid provisions which in their economic effect come as closely as legally possible to such invalid provisions.
