Forward-Looking Statements

Certain statements in this correspondence may contain forward-looking
information regarding the NYSE and Archipelago and the combined company after
the completion of the transactions that are intended to be covered by the safe
harbor for "forward-looking statements" provided by the Private Securities
Litigation Reform Act of 1995. These statements include, but are not limited to,
the benefits of the business combination transaction involving NYSE and
Archipelago, including future financial and operating results, the new company's
plans, objectives, expectations and intentions and other statements that are not
historical facts. Such statements are based upon the current beliefs and
expectations of NYSE's and Archipelago's management and are subject to
significant risks and uncertainties. Actual results may differ from those set
forth in the forward-looking statements.

The following factors, among others, could cause actual results to differ from
those set forth in the forward-looking statements: the ability to obtain
governmental approvals of the transaction on the proposed terms and schedule;
the failure of NYSE members or Archipelago shareholders to approve the
transaction; the risk that the businesses will not be integrated successfully;
the risk that the cost savings and any other synergies from the transaction may
not be fully realized or may take longer to realize than expected; disruption
from the transaction making it more difficult to maintain relationships with
customers, employees or suppliers; competition and its effect on pricing,
spending, third-party relationships and revenues; social and political
conditions such as war, political unrest or terrorism; general economic
conditions and normal business uncertainty. Additional risks and factors are
