                                  (UNAUDITED)



I.   OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
Basis of Presentation

  The consolidated financial statements of Desktop Data, Inc. (the Company)
presented herein have been prepared pursuant to the rules of the Securities and
Exchange Commission for quarterly reports on Form 10-Q and do not include all of
the information and note disclosures required by generally accepted accounting
principles.  These financial statements should be read in conjunction with the
Company's consolidated financial statements and notes thereto for the year ended
December 31, 1994 included in the Company's Form S-1 dated August 11, 1995.  In
the opinion of management, the accompanying unaudited consolidated financial
statements include all adjustments, consisting of only normal recurring
adjustments, necessary to present fairly the consolidated financial position,
results of operations and cash flows of the Company and its subsidiaries.
Quarterly operating results are not necessarily indicative of the results which
would be expected for the full year.

Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries, Desktop Data Canada, Inc. and Desktop
Data Securities Corp.  All material intercompany accounts and transactions have
been eliminated in consolidation.

Cash and Cash Equivalents

  At September 30, 1995, cash and cash equivalents included approximately
$24,700,000 in repurchase agreements, $5,298,000 in money market investments,
and $986,000 in U.S. Treasury Bills.

Pro forma Net Income (Loss) Per Common and Common Equivalent Share

  For the three and nine month periods ended September 30, 1995 and 1994, pro
forma net income (loss) per common and common equivalent share is computed by
dividing net income (loss), less the charge for the accretion of the Series B
preferred stock, by the pro forma weighted average number of common and dilutive
common stock equivalent shares outstanding during that period, plus the weighted
average number of shares of common stock issuable upon conversion of all shares
of Series A, Series C and Series D preferred stock and the weighted average
number of shares of common stock issued in the initial public offering
sufficient to generate proceeds for the payment of dividends on the Series A
preferred stock which were paid upon consummation of the initial public
offering.  Stock options granted after July 1, 1994 have been reflected as
outstanding for all periods presented, using the treasury stock method required
by the Securities and Exchange Commission.  Other common stock equivalents have
not been included for the periods presented, as the amounts would be
antidilutive.  Historical net income (loss) per share data has not been
presented, as such information is not considered to be relevant or meaningful.

2.  STOCKHOLDERS' EQUITY (DEFICIT)

Initial Public Offering

  On August 11, 1995, the Company completed an initial public offering of
1,977,000 shares of its common stock, including 300,000 shares granted to the
underwriters upon exercise of their over-allotment 

                                       6

option. The proceeds to the Company, net of underwriting discounts, commissions
and offering expenses, were approximately $26,711,000.

            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)



Convertible Preferred Stock

Concurrent with the above offering, the following transactions occurred:

  Upon the closing of the initial public offering, the Series A, Series C and
Series D preferred stock was converted into an aggregate of 3,847,123 shares of
common stock.  In addition, the Company paid cash dividends of approximately
$2,009,000 and $629,000 on the Series A and Series B preferred stock,
respectively.

  In accordance with the underlying agreement, the mandatory redemption
requirement related to the Series B preferred stock was relieved upon the
Company's initial public offering as the offering price exceeded $13.10 per
share.  As such, the currently redeemable portion of the Series B has been
reclassified to long-term in the September 30, 1995 consolidated balance sheet.

  On June 26, 1995, the Company's stockholders approved a new class of
undesignated preferred stock, which became effective upon the closing of the
Company's initial public offering.

3.  STOCK SPLIT

  On June 26, 1995, the Company's stockholders approved a 1-for-2.25 reverse
stock split of the common stock.  The reverse stock split has been retroactively
reflected in the accompanying consolidated financial statements and notes for
all periods presented.

4.  STOCK PLANS

1995 Stock Plan

  On June 26, 1995, the Company's stockholders approved the 1995 Stock Plan (the
1995 Plan).  The 1995 Plan is administered by the Board of Directors and
provides for stock awards, direct purchases and the grant of options to purchase
shares of the Company's common stock.  A maximum of 625,000 shares may be issued
under this plan.  As of September 30, 1995, the Company has not made any grants
or awards under this plan.

1995 Non-Employee Director Stock Option Plan

  On June 26, 1995, the Company's stockholders also approved the 1995 Non-
Employee Director Stock Option Plan (the 1995 Director Plan), for which 100,000
shares of the Company's common stock have been reserved.   The purpose of the
1995 Director Plan is to attract and retain qualified persons who are not also
officers or employees of the Company (the Eligible Directors) to serve as
Directors of the Company.  Under the 1995 Director Plan, any Eligible Director
shall automatically be granted an option to purchase 5,000 shares of common
stock on the effective date of election at an option price equal to the fair
market value on the date of grant, and an option to purchase 2,500 shares of the
common stock on the date of each successive Annual Meeting of the Stockholders,
if such Director has attended at least 75% of the meetings of the Board during
the past fiscal year.  Options granted under this plan expire ten years from the
date of grant.  As of September 30, 1995, the Company has not made any grants
under this plan.

1995 Employee Stock Purchase Plan

  On June 26, 1995, the Company's stockholders approved the 1995 Employee Stock
Purchase Plan (the 1995 Purchase Plan).  This plan permits eligible employees to
purchase the Company's common stock at 85% of the fair market value of the stock
on the first or last date of each semi-annual plan period, whichever is lower.
The 1995 Purchase Plan covers substantially all employees, subject to certain
limitations.  An eligible employee may elect to have up to 10% of his or her
total compensation, as defined, withheld and applied toward the purchase of
shares in such a plan period (not to exceed $25,000 in any year).  At September
30, 1995, 175,000 shares of common stock were reserved for purchases under the
1995 Purchase Plan.  As of September 30, 1995, there have been no purchases to
date under the 1995 Purchase Plan.

5.  COMMITMENTS

  On August 31, 1995, the Company entered into an operating lease for office
facilities, expected to commence in January, 1996 and expiring in fiscal 2003.
The Company will pay out a total of approximately $2.3 million in monthly lease
payments over the period of the lease.  The Company has paid approximately
$76,000 related to an initial security deposit on the lease.

ITEM 2             MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

  Desktop Data, through its NewsEDGE service and software, delivers a large
variety of news and information sources in real time to personal computers and
workstations installed on LANs, automatically monitors and filters the news, and
alerts the users to stories of interest to them.

  The Company's revenues consist primarily of NewsEDGE subscription fees and
related royalties received from news providers in connection with sales of their
newswires through NewsEDGE.  Historically, royalties have constituted less than
10% of this amount.  The Company's other revenues consist principally of
NewsEDGE installation services and related computer hardware system sales, and
non-recurring custom development projects related to the Company's software.

  NewsEDGE subscriptions are generally for an initial term of twelve months,
payable in advance, and are automatically renewable for successive one year
periods unless the customer delivers notice of termination prior to the
expiration date of the then current agreement.  NewsEDGE subscription revenues
are recognized ratably over the subscription term, beginning on installation of
the NewsEDGE service.  Accordingly, a substantial portion of the Company's
revenues are recorded as deferred revenues until they are recognized over the
license term.  The Company does not capitalize customer acquisition costs.

  Certain newswires offered by the Company through NewsEDGE are purchased by the
customer directly from the news provider and payments are made directly from the
NewsEDGE customer to the provider.  For some of these newswires, the Company
receives ongoing royalties on payments made by the customer to the news
provider, and those royalties constitute part of the Company's subscription and
royalty revenues.  For other newswires that are resold by Desktop Data to the
NewsEDGE customer, the Company includes a fee for the newswire in the NewsEDGE
subscription fee paid by the customer and pays a royalty to the news provider.
Such royalties are included in the Company's cost of revenues.

RESULTS OF OPERATIONS FOR THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30,
1995

  Total revenues increased 52%, from $3.9 million for the three months ended
September 30, 1994 to $5.9 million for the three months ended September 30,
1995.  Year-to-date total revenues increased 62% to $16.4 million as compared to
$10.2 million for the same nine month period last year.  In the third fiscal
quarter, subscription and royalty revenues increased 61% to $5.6 million, up
from $3.5 million for the same period in 1994.  Year-to-date subscription and
royalty revenues increased 71% to $15.4 million from $9.0 million for the nine
months ended September 30, 1995 and 1994, respectively.  Other revenues
decreased 22% to $334,000 and 12% to $1.0 million, respectively,  for the three
and nine month periods ended September 30, 1995, from $428,000 and $1.1 million,
respectively, for the same periods in 1994.  The increase in subscription and
royalty revenues was due to increased subscription revenues from new customers,
the retention and growth of revenues from existing customers and increased
royalties from the sale of third party information news.  The decrease in other
revenues was due to fewer computer hardware system sales and non-recurring
custom development projects offset by increased installations.

  The number of installed customers increased from 250 customers at September
30, 1994, to 313 customers at September 30, 1995, an increase of 25%.  The
number of authorized users within customer organizations increased from 34,900
users at September 30, 1994 to 68,915 users at September 30, 1995, an increase
of 97%.  The average users per customer increased from 130 users at September
30, 1994 to 212 users at September 30, 1995, an increase of 63%.  The Company's
average revenues per customer increased from $40,474 for the nine months ended
September 30, 1994 to $54,330 for the nine months ended September 30, 1995, an
increase of 34%.

                                       9
<PAGE>
 
  Cost of revenues as a percentage of total revenues decreased slightly to 27%
for the three months ended September 30, 1995, as compared to 28% for the three
months ended September 30, 1994, and remained constant at 28% for the nine
months ended September 30, 1995, and 1994.

  Customer support expenses increased 25% to $683,000 for the three months ended
September 30, 1995, as compared to $546,000 for the same period in 1994.  Year-
to-date customer support expenses increased 36% to $1.8 million for the nine
months ended September 30, 1995, as compared to $1.3 million for the same period
in 1994.  These increases result primarily from higher staffing levels and the
continuing need for the Company to provide additional support to its growing
customer base.  As a percentage of total revenues, customer support expenses
declined to 11% for the three and nine month periods ended September 30, 1995
versus 14% and 13%, respectively, for the comparable periods in 1994.

  Development expenses increased 63% to $747,000 for the three months ended
September 30, 1995, as compared to $457,000 for the three months ended September
30, 1994.  Year-to-date development expenses increased 50% to $2.0 million for
the nine months ended September 30, 1995, as compared to $1.4 million for the
comparable period in 1994.  Development expenses increased as a result of higher
staffing levels to provide for enhancements of existing features and the
development of new features.  Development expenses, as a percentage of total
revenues, remained relatively constant at 13% and 12% for the three and nine
month periods ended September 30, 1995, respectively, and 12% and 13% for the
comparable periods in 1994, respectively.

  Sales and marketing expenses increased 44% to $2.3 million and $6.4 million,
respectively, for the three and nine month periods ended September 30, 1995, as
compared to $1.6 million and $4.4 million for the same periods in 1994.  Sales
and marketing expenses represented 38% and 39% of revenues for the three and
nine months ended September 30, 1995, respectively, as compared to 40% and 44%
for the same periods in 1994.  Sales and marketing expenses increased during
these periods, primarily due to the expansion of the sales and marketing
organizations.  As a percentage of total revenues, however, sales and marketing
expenses decreased primarily as a result of the increase in the Company's
revenues, without a corresponding increase in sales and marketing expenses.

  General and administrative expenses increased 24% to $281,000 from $226,000
for the three months ended September 30, 1995 and 1994, respectively.  Year-to-
date general and administrative expenses increased 30% to $835,000 from $640,000
for the nine months ended September 30, 1995 and 1994, respectively.  The
increases in general and administrative expenses were due primarily to additions
to staff to support the Company's growth.  General and administrative expenses,
as a percentage of total revenues, decreased to 5% for the three and nine month
periods ended September 30, 1995, versus 6% for the comparable periods in 1994.
The decrease as a percentage of total revenues is primarily due to the increase
in the Company's revenues, without a corresponding increase in general and
administrative expenses.

  Interest income (expense), net increased to $283,000 and $440,000 in the three
and nine month periods ended September 30, 1995, respectively, from $27,000 and
$57,000 in the comparable periods in 1994 due to both the interest earned on
higher cash balances generated from operations and the proceeds from the
Company's initial public offering, and higher interest rates paid on invested
cash balances.

  No provision for income taxes was made for the three and nine month periods
ended September 30, 1994 because the Company experienced a net operating loss
for such periods.  The provision for income taxes of $49,000 and $81,000 for the
three and nine month periods ended September 30, 1995, respectively, represent
the alternative minimum tax due under the Internal Revenue Code and state taxes
due in states that do not have net operating loss carryforwards available.

LIQUIDITY AND CAPITAL RESOURCES

  The Company's cash and cash equivalents balance was $32.4 million at September
30, 1995, as compared to $4.1 million at December 31, 1994, an increase of $28.3
million.  Net cash generated from operations increased from $1.4 million for the
nine months ended September 30, 1994 to $5.1 million for -the comparable period
in 1995, due to profitable operations together with the continued growth in
subscription fees and increased deferred revenue resulting from advanced
payments received from customers.  Net cash used for investing activities for
the nine months ended September 30, 1995 was $948,000, due primarily to capital
expenditures required to support the expansion and growth of the business.  Net
cash provided by financing activities in the nine months ended September 30,
1995 was $24.1 million (net), $26.7 of net proceeds from the initial public
offering, offset by $2.6 million in payments of dividends on Preferred stock.

  The Company believes that its current cash balances and funds anticipated to
be generated from operations, will be sufficient to satisfy working capital and
capital expenditure requirements for the foreseeable future.
