Q & A for Dime Bancorp Employees



What can you tell me about Washington Mutual?

Washington Mutual is a national financial services company that provides a
diversified line of products and services to consumers and small-to-midsize
businesses. The company is the
   3

                                                                               3

nation's seventh-largest financial institution with $ 219.93 billion in assets
as of March 31, 2001. For the first quarter of 2001, Washington Mutual reported
record earnings of $641 million.

               Headquartered in Seattle where it was founded in 1889, Washington
Mutual operates more than 2,300 consumer banking, mortgage lending, business
banking, consumer finance and financial services offices throughout the nation.
In the past 15 years, the company has successfully completed 28 acquisitions.

Washington Mutual's goal is to create two leading national franchises: one in
banking and financial services and another in mortgage lending. Additionally,
one of the company's key strategies is to grow its commercial portfolio in order
to diversify over time its sources of revenue.

               Washington Mutual is the nation's No.1 mortgage originator and
loan servicer and has more than 800,000 Internet banking customers. The company
has been in the news recently for its successful launch of Occasio(TM), an
entirely new concept in customer-friendly retail banking delivery, in its Las
Vegas and Phoenix markets, also planned for the Atlanta market next year.

Money magazine said of WaMu's retail financial services strategy, "WaMu has
turned superior customer service into a potent marketing tool." About its
mortgage banking operations, Mortgage Banking magazine said, "Washington Mutual
has what politicians like to call the 'big mo' - momentum."

Washington Mutual has been recognized by Fortune magazine as one of the best
companies for minorities and one of the most admired companies in the
mortgage-finance industry. It has also been named winner of the Best Customer
Satisfaction Award for the financial services category by Satmetrix Systems and
cited by the nationally known Catalyst Group and Working Woman magazine for its
women in leadership and management.

Why did Washington Mutual choose The Dime?

The transaction will provide a platform for growth in the nation's top banking
market and enhance WaMu's national leadership position in mortgage originations
and servicing. Like Dime, Washington Mutual has built its successful business by
serving as a customer-friendly alternative to the large commercial banks in its
markets. The combination of Washington Mutual and The Dime is a perfect fit,
tailor-made to deliver solid results to customers, communities and shareholders.
The combined company will be well positioned to build upon The Dime's consumer
and business banking track record in the greater New York area and to expand its
mortgage lending activities nationally. In addition, the Dime's commercial
banking business will accelerate WaMu's strategy to diversify its sources of
revenue through business banking and specialty finance.

When will the merger be completed?

                                                                               4

The transaction is expected to close in first quarter 2002, subject to Dime
Bancorp shareholders' and banking regulators' approval. The integration should
be completed during second quarter 2002.

Will The Dime's and NAMCo's names change?

Yes. However, while The Dime's and NAMCo's honored names will change, the
company's legacy - commitment to customer service and to the middle-market
consumer and to its communities - will continue.

What is Occasio(TM)?

Occasio(TM) is WaMu's new concept in customer-friendly retail banking delivery.
It's aimed at revolutionizing the industry by eliminating teller windows and
providing a concierge, a children's play area and many other retail-style
amenities. The company has successfully launched Occasio(TM) branches in Las
Vegas and Phoenix, and will introduce them to the Atlanta market next year.

               What will happen between now and the time the deal closes? May I
contact my counterparts at Washington Mutual?

Please refrain from contacting your counterparts at Washington Mutual. Until the
transaction closes, it will be business as usual for both companies. It is
important for employees of both companies to continue to focus on their business
goals and to take care of our customers.

How will The Dime be managed after the transaction closes?

The Dime's various units and divisions will join with Washington Mutual's
respective groups. As the merger has just been announced, many decisions and
details have yet to be been finalized.

Who will lead the integration team?

An experienced acquisitions team from Washington Mutual will work with The Dime
management to coordinate the integration. Washington Mutual's Senior Executive
Vice President of Corporate Services, Steve Freimuth, will lead the team. The
Dime executive leading the integration team will be named shortly.

Many key managers from both companies will be asked to assist. Plans and
progress will be communicated to employees of The Dime through Washington
Mutual's merger newsletter, Connections, as well as Dime Express, Dime World
video and other channels.

Will there be any branch or lending office consolidations?

There is no overlap between the retail banking distribution networks of
Washington Mutual and The Dime, and there are no branch consolidations planned.
In fact Washington Mutual plans to expand the Dime network going forward. There
will be consolidation of lending offices within
   5

                                                                               5

overlapping common markets and of corporate and administrative functions.
Eligible employees who are displaced will receive severance pay, outplacement
assistance and priority consideration in applying for other jobs within the
company.

When will employees learn the status of their positions?

The integration team will begin working soon on bringing the two companies
together. While it is too early to know which specific positions will be
affected, Washington Mutual and The Dime are committed to communicating this
information as soon as it is known.

        What is The Dime's severance plan for employees displaced during a
merger such as this?

Details of the severance plan will be communicated to all employees in the near
future.

How will customers learn about this transaction?

Many customers will have learned of the transaction through the media, others
will learn about it through communications sent by The Dime in the coming days
and weeks. Each customer contact employee will receive a special Q&A shortly
addressing customer concerns.

What should I say if contacted by the media?

As always, refer all calls from the media to Tom Ducca in the Public Relations
Department at (212) 326-6962.

If I have any other questions, whom should I call?

You should feel free to ask any questions of your manager, your departmental
manager, or your executive manager. While it will take time for some decisions
to be made, we are committed to understanding your questions and keeping
everyone informed on the progress of this important transaction.

Employees may also call an employee hotline specially set up to answer merger

THE FOLLOWING IS A COPY OF A NOTIFICATION RELATING TO THE MERGER DISTRIBUTED ON
WASHINGTON MUTUAL'S INTRANET.

STORY FOR WAMU INTERNAL INTRANET:



WAMU TO ACQUIRE THE DIME


This morning Washington Mutual announced that it has agreed to acquire Dime
Bancorp, headquartered in New York City, and its subsidiaries The Dime Savings
Bank of New York, FSB, and North American Mortgage Company (NAMCo).

The transaction will provide a platform for growth in the nation's top banking
market and enhance WaMu's national leadership position in mortgage origination
and servicing. Known as "The Dime," Dime Bancorp operates 123 financial centers
in the greater New York area and 233 mortgage origination offices in 40 states
through its subsidiary North American Mortgage Co. (NAMCo). The Dime has assets
of $27 billion.

"The combination of Washington Mutual and The Dime is tailor-made to deliver
solid results to our customers, our communities and our shareholders," says
Chairman Kerry Killinger. "It's a perfect fit."

The combined company will be positioned to build upon The Dime's consumer
banking franchise in the greater New York area as well as NAMCo's nationwide
mortgage origination and servicing operations. In addition, The Dime's
commercial banking business supports WaMu's strategy to diversify, over time,
its sources of revenue through business banking and specialty finance.

        Shared values

Founded in 1859 to serve those who saved in 10-cent increments, The Dime, like
WaMu, has built its business by serving as an alternative to the large
commercial banks in its markets. The company's tag line, "You're Worth More at
the Dime," illustrates its philosophy of putting the customer first.

"With more than $500 billion in deposits, the greater New York market offers a
terrific new market for our customer-friendly brand of consumer banking," says
Deanna Oppenheimer, president of Banking and Financial Services. WaMu plans to
introduce Occasio financial stores to the greater New York area, augmenting The

               Home Loans & Insurance Services will be the No. 1 mortgage
originator in New York state when the transaction closes. In addition, "NAMCo's
origination volume and servicing portfolio will cement WaMu's position as the
nation's leading mortgage lender and largest loan servicer," says Craig Davis,
president of Home Loans & Insurance Services. In addition, the acquisition will
also make WaMu the No. 1 originator in the states of Rhode Island and Nevada.

The Dime's other lines of business include business banking, private banking,
indirect auto lending, financial services, insurance and commercial real estate.

The transaction is expected to close in the first quarter 2002, pending approval
by Dime Bancorp's shareholders and by regulators. Systems conversions should be
complete by second quarter 2002.

                                                          Date:  June 25, 2001



I'm writing to tell you of exciting news. This morning we announced an agreement
for Seattle-based Washington Mutual, to acquire our company. With assets
totaling $219.93 billion (as of March 31, 2001), Washington Mutual is the
country's largest thrift. Through this transaction, we will be creating one of
the most attractive banking franchises in financial services today. By uniting
two strong companies with highly complementary strengths, we will be creating
tremendous value and opportunities for our employees, customers, shareholders
and communities.

Washington Mutual is one of the fastest growing companies in financial services
with a strong focus on customer service and community lending. Their rapidly
growing leadership position in mortgage origination, when combined with our
strong mortgage lending business, will create an unrivaled coast-to-coast
franchise serving a majority of the country's most attractive and fastest
growing markets. Similar to Dime, Washington Mutual has built its banking
business by serving as an attractive alternative for consumers and small
businesses to the larger commercial banks in its markets. It also shares many
values with Dime, providing a common strong foundation for our new company. We
both have a strong focus on satisfying customers, delivering quality and
achieving sustainable and superior growth. And, we both share a deep commitment
to our employees, customers and communities.

The combined company marks Washington Mutual's banking entrance into the
Northeast and it will build upon Dime's consumer banking franchise in the
greater New York area, as well as our nationwide mortgage origination and
servicing operations. Together, we will have the resources to make the
investments necessary to be a leader in financial services. Our focus will
continue to be on growing and being the best in our business. While some job
reductions may occur in areas of overlap, we anticipate that they will be
mitigated by the combination of normal attrition at Dime coupled with Washington
Mutual's anticipated company-wide growth and its customary practice of filling
vacancies from within.

        Implementation planning will begin immediately. As it progresses, we
will keep you fully informed. The new company will retain the Washington Mutual
name. The attached communications materials, including a news release, Q&A and a
Washington Mutual fact sheet, provide more details.

        I am very excited about the tremendous potential of our new
organization. We will be a powerful, growth-oriented company able to compete on
a national level in the most attractive markets and businesses. By joining
forces, we will have even greater opportunities to serve customers, grow
professionally and personally, and continue to create value for shareholders.

        As we build a great new company together, I'm confident that the best is
yet to come.
