NOW, THEREFORE, in consideration of the mutual promises set forth below and other good and valuable consideration the receipt of which is hereby acknowledged, effective October 1, 2005, State Street and ABRA hereby agree as follows:

1. The last sentence of Section 7.06(b) is amended in its entirety to read as follows: “State Street and ABRA acknowledge that the earnings attributable to Trust assets transferred to such account shall accrue to the benefit of State Street and have been taken into account in their negotiations with respect to the fees payable to State Street under Section I of Appendix C attached hereto, and in furtherance thereof, State Street shall, from time to time as reasonably requested by ABRA, provide to it an accounting of the amount of such earnings.”

2. Section 8.01 is amended in its entirety to read as follows:

“State Street shall market the Program through the ABRA Program Services Unit to persons and entities who are Qualified Employers or who reasonably can be expected to become Qualified Employers. No later than the Board meeting during the third calendar quarter of 2005 and of each year thereafter until the Transfer Completion Date, State Street shall deliver to ABRA a proposed Annual Marketing Plan for the next succeeding calendar year. Each proposed Annual Marketing Plan shall contain proposals describing marketing activities and sales goals for the applicable period. Marketing activities shall include one or more of the following activities: (a) Creation of print materials and production of such materials, including, but not limited to, concepts, design work for literature and advertisements and advertisement placement; (b) purchase of images, photography and other art; (c) marketing website redesign, content development, optimization and ongoing maintenance of such content and web platform, to the extent not otherwise required by Section 6.05; (d) media for print and internet; (e) public relations; (f) events at seminars, conferences and other venues; (g) referral programs; (h) project management; (i) any other activities that State Street may designate. Each

proposed Annual Marketing Plan also shall contain sales goals for the number of additional new Plans, net additional participants and new assets for the year derived from contributions and conversions less assets associated with Plans that cease participation in the Program (excluding assets withdrawn from the Program due to distributions to Participants on account of termination of employment, hardship or similar events) to be added to the Program, provided that such goals shall include (i) an increase of 14,500 net additional Participants by December 31, 2008 over the number of Participants as of December 31, 2002, and (ii) a description of the information (including demographic and other data as may be reasonably requested by ABRA) relied upon and the methodology used by State Street to develop such plan and sales goals. The proposed Annual Marketing Plan shall be presented in sufficient detail to enable ABRA to evaluate the level and type of effort, including the amount of the direct costs thereof, to be expended by State Street in carrying out such plan, it being understood that such expenditures shall in no event be less than (i) for the proposed marketing activities, $731,000 for 2005, and $900,000 for each of 2006, 2007 and 2008; and (ii) to achieve the proposed sales goals, $1,400,000 for each of 2005, 2006, 2007 and 2008.

ABRA shall review each such proposed Annual Marketing Plan and shall be entitled to make recommendations to State Street regarding such plan and the various marketing activities and sales goals set forth therein. ABRA and State Street shall consult with each other in good faith for the purpose of agreeing to such Annual Marketing Plan and marketing activities and sales goals set forth therein, prior to the meeting of the Board during the fourth calendar quarter during the year preceding the year covered by such plan. State Street shall carry out the Annual Marketing Plan as so agreed and shall use its best efforts to carry out the marketing activities and to achieve the annual sales goals established thereby. Notwithstanding the foregoing, ABRA and State Street may agree that the minimum amounts required to be expended pursuant to the Annual Marketing Plan for years beginning after December 31, 2005 shall be reallocated among marketing activities and the achievement of sales goals, provided that the aggregate annual amount of such expenditures shall in no event be less than $2,300,000.”
