                MRO SOFTWARE URGES DATASTREAM BOARD TO NEGOTIATE


BEDFORD, MASS., January 9, 2002 - MRO Software, Inc. (Nasdaq: MROI), the leading
provider of e-Business solutions for asset-intensive companies, today announced
that it has responded to Datastream's refusal to enter into discussions
regarding MRO Software's acquisition proposal. In a letter sent today, MRO
Software urged Datastream's management and board to open negotiations.

On December 20, 2001 MRO Software made an offer to purchase Datastream Systems,
Inc. for a price of $6.00 per share, consisting of $1.00 in cash and $5.00 in
the form of MRO Software common stock, at the time representing a premium of 45%
over Datastream's average closing price over the prior 15 trading days ($4.15
per share). Datastream subsequently acknowledged the offer and said its board
would evaluate the offer. On January 8, Datastream distributed a press release
and letter announcing its decision to reject MRO Software's offer.

"The logic behind this combination remains compelling," said Chip Drapeau,
president and CEO, MRO Software. "The response from the capital markets and
Datastream shareholders to our offer signals significant support for opening
negotiations regarding our proposal. We are disappointed by Datastream's
unwillingness to sit down and enter into even preliminary discussions with us.
We've made it clear that we would be willing to increase our offer if

                                       1


Datastream's management would come to the table, justify additional value, and
negotiate on behalf of their stockholders."

MRO Software's January 9, 2002 response letter is attached.

This press release and its attachment contain forward-looking statements (within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended). The Company's
actual results may differ materially from those suggested by the forward-looking

expectations, difficulties in retaining Datastream personnel necessary for the
combination to succeed, difficulties integrating the products or technologies of
the two companies and providing migration paths for customers, difficulties in
effectively distributing the two companies' products through the combined sales
force and channels, difficulties in retaining Datastream's existing customers
and revenue streams, difficulties in achieving market or operational synergies,
liabilities of Datastream that that are neither currently known nor disclosed
before the acquisition is consummated, the termination of contracts for supply
by key vendors of Datastream (including suppliers of technology) as a result of
the transaction, and those reasons discussed in the section "Factors Affecting
Future Performance" in our most recent Quarterly Report on Form 10-Q as filed
with the Securities and Exchange Commission.

January 9, 2002


Mr. Larry Blackwell
Chairman of the Board, Chief Executive Officer and President
Datastream Systems, Inc.
50 Datastream Plaza
Greenville, SC 29605

Dear Larry:

We are naturally disappointed that you and your Board have refused to meet with
us to explore a negotiated combination of our two companies. The very positive
market reaction to our proposal-your stock went up over 50%-suggests that the
reasons cited by your Board for refusing to even explore the potential
transaction with us are not credited by the capital markets or Datastream
stockholders.

You are right that MRO Software stock, like many software company stocks, is
volatile. Fortunately for MRO stockholders, our stock enjoys a liquid market and
over time has performed very well especially in light of the bursting of the
Internet bubble last year. Datastream's stock, on the other hand, has a much
thinner float and has had mediocre performance in the marketplace. A number of
your stockholders have expressed to us extreme disappointment with Datastream's
stock price and its financial performance.

As fiduciaries, we both know that a decision not to pursue a potentially very
attractive opportunity for our stockholders is required to be made based on all
the information practically available. We would have expected you and your Board
to recognize that rejecting a friendly proposal without even exploring its
potential is ill-advised. Despite Datastream's operating performance this
quarter relative to analyst expectations (significantly reduced by you during
the course of the year), your results represent material declines from prior
year total revenues, software revenues and pro forma earnings. This will be
Datastream's second straight year of annual decline. If you can demonstrate that
Datastream's operating performance is no longer in decline and is capable of
improving on a sustainable basis, we are open to being persuaded that a higher
price or a different mix of CONSIDERATION can be justified. Your Board's refusal
to meet, however, suggests that it either fears a higher offer or cannot justify
one based on objective evidence. The rhetoric in your letter is no substitute
for facts.

While it is not surprising that you would include an advertisement for
Datastream's products in your letter, we think the objective record tells a
different story. Datastream 7i is substantially based on an old architecture
from one of your acquired legacy applications that you repackaged as a quick
response to the introduction of MAXIMO 5.0. Repackaging of older products is
rarely a recipe for sustainable competitive advantage. It is this very fact that
makes the timing of this transaction so important to Datastream stockholders and
customers.

                                       4



If, as you claim, your "Board of Directors and management are committed to
maximizing the value of our stockholders' investment," you should meet with us
to negotiate a transaction that will accomplish that objective for both our
companies' stockholders. If you truly believe that our current offer is
inadequate, you should meet with us and demonstrate why a higher price is
justified. While we would much prefer to proceed on a negotiated basis, your
Board should understand that we are not limiting ourselves to a negotiated
transaction. We believe the benefits of the combination for both companies'
stockholders are too compelling to simply abandon our efforts.

Larry, it's time to focus on the bigger picture. Together our companies will be
a strong and stable platform for growth and expansion. I look forward to hearing
from you and I hope that you and your Board will reconsider and meet with us
promptly to achieve a transaction in the best interests of Datastream's and
MRO's stockholders.


Sincerely,



Robert L. Daniels
Chairman of the Board
