NFB PROPOSAL - WHAT NFB WANTS YOU TO BELIEVE
- -------------------------------------------------------------------------------



- --------------------------        ---------------------------------------------------------------------------------
  THE CLAIM IS:                     THE FACTS ARE:
- --------------------------        ---------------------------------------------------------------------------------




                                
SIGNIFICANTLY ACCRETIVE            Using NFB's assumptions, the NFB Proposal 15% EPS dilutive to Dime's
                                   shareholders in 2001

SIGNIFICANT PREMIUM                Would have represented a discount to Dime's share price as little as 6
                                   months ago and an average premium of less than 10% during all of 1999

ACHIEVABLE ASSUMPTIONS             Cost savings assumptions represent 64% of Dime's operating expense
                                   base (excluding NAMCO(1)), implying a 15% marginal efficiency ratio for
                                   Dime.  No revenue run-off taken into account, despite anticipated sale to
                                   FleetBoston of 14% of Dime's deposit base

LOW RISK TRANSACTION               NFB's unrealistically high level of projected cost savings, when coupled with
                                   hostile nature of proposal, underscores high degree of execution risk

A REAL OFFER                       NFB has a history of abandoning unsolicited approaches.  NFB Proposal is
                                   highly contingent upon terms and conditions which will not be met

RELEVANT PRIOR ACQUISITION         Dime is more than seven times the size of the largest transaction NFB has
EXPERIENCE                         ever completed and three times the size of all their acquisitions put together

                   (excluding NAMCO) and 4% if looked at on the basis of NFB's
                   operating expenses

              o    No revenue run-off projected despite anticipated sale of 14%
                   of Dime's most attractive deposits to FleetBoston for a below
                   market premium
