                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                       
A.   Basis of Presentation

          The financial information included herein, with the exception of the
     consolidated balance sheet at June 30, 1995, has not been audited.
     However, in the opinion of management, all material adjustments necessary
     for a fair presentation of the results for these periods have been
     reflected and consist only of normal recurring accruals, a $20,718,000
     charge to operations recorded in the third quarter of FY1996 (which is
     more fully described in Footnote C), and a $1,700,000 charge to operations
     recorded in the first quarter of FY1996 (which is more fully described in
     Footnote D).  The results for these periods are not necessarily indicative
     of the results for the full fiscal year.  Certain amounts reported for the
     prior periods presented have been reclassified to be consistent with the
     current year's presentation.

          The accompanying financial information should be read in conjunction
     with the consolidated financial statements and notes thereto contained in
     the Company's annual report on Form 10-K filed with the Securities
     Exchange Commission for the year ended June 30, 1995.

B.   Pending Reorganization

          On January 23, 1996 the Company announced plans to combine its
     internetworking operations including the merger of its 95%-owned
     subsidiary BBN Planet Corporation ("BBN Planet") and its wholly owned
     subsidiary BBN HARK Systems Corporation ("BBN HARK") into BBN Corporation.
     BBN Domain Corporation ("BBN Domain") remains a wholly owned subsidiary of
     the Company.   The Company is currently in discussions with the minority
     shareholders of BBN Planet, including AT&T Venture Company, L.P., which
     currently owns 1,000,000 shares of the Series A Convertible Preferred
     Stock of BBN Planet, to determine the number of shares of the common stock
     of the Company the Company would issue to such holders in exchange for
     their shares of BBN Planet upon the combination of BBN Planet with the
     Company.

          In exchange for an agreement to cancel the outstanding options to
     purchase shares of common stock of BBN Planet and BBN HARK, the Company
     has agreed to grant substitute options to holders of BBN Planet and BBN
     HARK options.  The exchange, when completed, will result in the issuance
     of approximately 225,000 BBN options which will vest principally over a
     twelve-month period.  The exchange of the BBN Planet options will result
     in the issuance of approximately 219,000 BBN options at a price below
     market value and will result in a charge to operations of approximately
     $2,400,000 which will be charged to expense over the vesting period, of
     which $1,500,000 was recorded in the third quarter of FY1996.  See
     Footnote C to the consolidated financial statements.

                                  (continued)

C.   Goodwill Write-Off and Other Charges

          In the third quarter of FY1996, the Company recorded a charge of
     approximately $20,718,000 to write off goodwill previously recorded in
     connection with the acquisitions of BARRNet and SURAnet in August 1994
     and March 1995, respectively, and certain other costs and employee
     related expenses in connection with its announced reorganization (see
     Footnote B to the consolidated financial statements).  The goodwill write-
     off was precipitated by a business evaluation, which included a review of
     the Company's current Internet-related business in comparison to
     expectations established at the time of the acquisitions.  The Internet
     services market has changed significantly and is continuing to develop
     rapidly, including the emergence of new competition, increasing downward
     pressure on prices, rapidly changing technology, and frequent new product
     and service introductions.  In response to this dynamic market and the
     opportunities which it presents, the Company decided to reorganize its
     business units, as described in Footnote B to the consolidated financial
     statements, to principally focus on the Internet.  The amount of the
     charge was determined in accordance with the provisions of Statement of
     Financial Accounting Standards No. 121, "Accounting for the Impairment of
     Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," ("SFAS
     121") which was issued by the Financial Accounting Standards Board in
     March 1995.  SFAS 121 requires recognition of an impairment loss when the
     sum of undiscounted expected future cash flows is less than the carrying
     amount of the assets.

D.   Operating Charge

          During the three months ended September 30, 1995, the Company
     recorded a charge of $1,700,000 at BBN Domain which is focusing its
     business on networked process optimization solutions for pharmaceutical
     and manufacturing companies. The charge is associated with severance and
     related costs and is included primarily in selling, general and
     administrative expense.  These costs were substantially paid during the
     six months ended March 31, 1996.

E.   Paid-in Capital

          As provided by the Company's 1986 Stock Incentive Plan, during the
     six months ended December 31, 1995 the retiring chairman of the board and
     certain other executive officers of the Company transferred shares of the
     Company's common stock to the Company in payment of applicable
     withholding taxes in connection with the exercise of non-qualified stock
     options.  The effect of these transactions was to reduce paid-in capital
     by approximately $3,436,000.

     contract research and development and includes the BBN HARK business;
     Internet activities includes BBN Planet's Internet access and value-added
     services business and the America Online contract; BBN Domain focuses on
     process optimization and clinical trial software for manufacturing and
     pharmaceutical customers; and LightStream Corporation, an 80%-owned
     subsidiary of the Company, sold substantially all of its assets on January
     11, 1995.

G.   Commitments and Contingencies

          The Company, like other companies doing business with the U.S.
     government, is subject to routine audit, and in certain circumstances to
     inquiry, review, or investigation, by U.S. government agencies, of its
     compliance with government procurement policies and practices.  Based
     upon government procurement regulations, under certain circumstances a
     contractor violating or not complying with procurement regulations can be
     subject to legal or administrative proceedings, including fines and
     penalties, as well as be suspended or debarred from contracting with the
     government.  The institution of such proceedings against the Company
     could, and suspension or debarment from contracting with the government
     would, materially adversely affect the Company's business, financial
     condition, and results of operations.  The Company's policy has been and
     continues to be to conduct its activities in compliance with all
     applicable rules and regulations.

                                BBN CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (continued)

G.   Commitments and Contingencies (continued)

          The books and records of the Company are subject to audit by the
     Defense Contract Audit Agency ("DCAA"); such audits can result in
     adjustments to contract billings.  Final contract billing rates for the
     Company have been established and billings audited for years through
     fiscal year 1991, except for the Company's former BBN Communications
     activities, for which final contract billing rates have been established
     and billings audited only through fiscal year 1984.  The audit by DCAA of
     the Company's former BBN Communications activities for fiscal years 1985
     through 1993, which had been delayed, is currently in progress.  U.S.
     government revenue for BBN Communications activities during the nine-year
     period under audit represented approximately 40% of the Company's total
     U.S. government revenue during the period.  DCAA has advised the Company
     that, based upon DCAA's interpretations of government contract
     regulations, DCAA intends to recommend to the responsible governmental
     administrative contracting officer that adjustments to BBN Communications
     contract billings be made which, if asserted and sustained upon appeal,
     would have a material adverse effect on the Company's financial condition
     and results of operations.  The amount of any adjustments which may
     ultimately be asserted by the administrative contracting officer
     following receipt of the DCAA recommendations is not currently
     determinable.  The Company and its counsel believe that DCAA's intended
     recommendations, in substantial part, are based upon incorrect
     interpretations of government contract regulations and are inconsistent
     with decided cases.  The Company expects that any adjustments which may
     ultimately be asserted and sustained on appeal as a result of audits of
     the Company's fiscal years 1985 through 1995 (including the 1985 through
     1993 period for BBN Communications) will not have a material adverse
     effect on the Company's financial condition and results of operations.

          In April 1991, the Company was informed that it was the subject of an
     investigation by U.S. government agencies of its compliance with certain
     government procurement policies and practices.  No allegations were made
     by the government agencies and the Company was informed in August 1995
     that the investigation had been concluded.

          The Company is subject to other legal proceedings and claims which
     arise in the ordinary course of its business.  In the opinion of
     management, the results of these other legal proceedings and claims will
     not have a material effect on the Company's consolidated financial
     position and results of operations.

H.   Recent Pronouncement

          In October 1995, the Financial Accounting Standards Board issued
     Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
     for Stock-Based Compensation," which is effective for the Company's
     FY1997 financial statements.  SFAS No. 123 allows companies to either
     account for stock-based compensation under the new provisions of SFAS No.
     123 or under the provisions of APB 25, but requires pro forma disclosure
     in the footnotes to the financial statements as if the measurement
     provisions of SFAS No. 123 had been adopted.  The Company expects to
     continue accounting for its stock-based compensation in accordance with
     the provisions of APB 25.  As such, the adoption of SFAS No. 123 will not
     impact the Company's financial position or the results of operations.

I.   Subsequent Event

          In April 1996, the Company entered into a capital lease agreement to
     finance certain equipment acquisitions.  The total cost of the assets to
     be covered by the lease is limited to $15,000,000.  The agreement
     includes a sale and leaseback of assets purchased during the nine months
     ended March 31, 1996 of approximately $7,000,000, and an $8,000,000
     commitment for assets to be purchased through September 30, 1996.  Assets
     acquired under the lease serve to collateralize the debt.  Each borrowing
     bears interest at an effective rate of 8.5% and has a term of thirty-six
     months, with principal and interest payable quarterly in advance.  The
     lease includes purchase and renewal options at fair market values.  The
     lease will be classified as a capital lease in accordance with Statement
     of Financial Accounting Standards No. 13, "Accounting for Leases".

[Underline]Forward-Looking Statements[End-Underline]
     This Report includes certain forward-looking statements about the
Company's revenue growth, including from its Internet-related activities,
expected expenses and operating losses, possible capital needs, and government
audit contingencies.  Any such statements are subject to risks that could cause
the actual results or needs to vary materially.  These risks are discussed in
the appropriate sections of this Report and in the Company's Report on Form 8-K
dated May 15, 1996 for its fiscal year ended June 30, 1995 filed with the
Securities and Exchange Commission.

[Underline]The Company[End-Underline]

     As of December 31, 1995, the Company consisted of four operating units:
BBN Systems and Technologies Division, BBN Domain Corporation, BBN Planet
Corporation, and BBN HARK Systems Corporation.  The BBN Systems and
Technologies Division included internetworking services and products, and
collaborative systems and acoustic technologies for both the government and
commercial markets.  BBN Domain Corporation ("BBN Domain"), a wholly owned
subsidiary of the Company, focused its business on data analysis and process
optimization software products for pharmaceutical and manufacturing
applications.  BBN Planet Corporation ("BBN Planet"), a 95% owned subsidiary of
the Company, provided managed Internet services to businesses and other
organizations.  BBN HARK Systems Corporation ("BBN HARK"), a wholly owned
subsidiary of the Company, was an early stage company which developed and
marketed commercial speech recognition software products.

     During FY1995, LightStream Corporation ("LightStream"), a previously 80%
owned subsidiary of the Company which made asynchronous transfer mode ("ATM")
network switches, sold substantially all of its assets to Cisco Systems, Inc.

     On January 23, 1996 the Company announced plans to combine its Internet
and internetworking services operations.  The Company believes this strategy
will enable BBN to focus principally on a broad range of Internet capabilities
and to develop new Internet-related offerings for businesses and other
organizations.  To achieve this objective, the Company will combine its
Internet-related activities into two principal business units, BBN Planet and
BBN Systems and Technologies.  The Company's reorganized BBN Planet business
unit will include the Company's managed Internet access and value-added
services and related network operations, the Company's contract with AT&T Corp.
("AT&T"), the America Online ("AOL") network management contract, and related
Internet dial-up access capabilities, and will be responsible for BBN's
Internet offerings to business customers.  The Company's reorganized BBN
Systems and Technologies business unit will focus on creating next-generation
technology for advanced Internet applications, and will continue to provide
networking solutions and contract research and development principally for the
federal government.  The Company's commercial speech recognition activities,
previously undertaken by BBN HARK, are being integrated into BBN Systems and
Technologies.  BBN Domain currently remains a wholly owned subsidiary of the
Company, focusing on process optimization and clinical trial software for
manufacturing and pharmaceutical customers.

     The following discussion of the results of operations for the three and
nine months ended March 31, 1996 and the comparable prior year periods is
presented on an as reorganized basis.

                                BBN CORPORATION
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

[Underline]Overview[End-Underline]
     The Company has historically derived the majority of its revenue from
contracts and subcontracts with the U.S. government, and currently
approximately one-half of the Company's revenue is derived from the U.S.
government and its agencies, particularly the Department of Defense.  The
Company's business with the Department of Defense has been adversely affected
by significant changes in defense spending.  Overall defense budgets have been
declining, and the Company expects this general decline and attendant increased
competition within the consolidating defense industry to continue over the next
several years.  Further, funding limitations could result in reduction, delay,
or cancellation of existing or emerging programs.  These factors have reduced
the Company's U.S. government revenue and operating margins in recent fiscal
periods.  The Company anticipates that competition in all defense-related areas
will continue to be intense and accordingly, that there will be continued
significant competitive pressure to lower prices, which may reduce
profitability in this area of the Company's business.

     For the past several years, BBN has provided network systems and services
to the U.S. Department of Defense, including the Defense Data Network ("DDN"),
a common-user data network servicing the Department of Defense.  In FY1991, the
Defense Information Systems Agency awarded BBN a one-year contract in support
of the DDN, with up to four one-year optional extensions.  The Company has
completed performing under the fourth option year of that DDN contract, valued
at approximately $15 million, for the contract year ended in October 1995.  In
April 1996, the Company completed performance under a six-month extension to
the DDN contract, valued at approximately $8.3 million.  The Company is
currently performing under an additional contract extension.  The Company is
competing for the new contract, which is expected to be announced by August
1996 at a reduced funding level.  Approximately $17.8 million and $20.5 million
of revenue has been recorded under the DDN contract in FY1995 and FY1994,
respectively. Fiscal year 1996 revenue is expected to approximate $16.1
million.

     The markets in which the Company competes are characterized by rapidly
changing technology, evolving industry standards, intense competition, and
frequent new service and product introductions, which require, among other
things, the Company to make significant and on-going investment.  In recent
years, the Company's traditional commercial businesses have been experiencing
substantially lower revenue.  The Company has discontinued sales of most of its
traditional X.25 systems and products, and has substantially eliminated its
development effort, and significantly reduced its selling efforts related to
this business.  In recent periods, the Company has invested heavily in
development of new products, including the LightStream ATM switch which was
sold to Cisco Systems, Inc. in January 1995, Cornerstone(TM) data analysis and
visualization software, the T/10(TM) Integrated Access Device ("IAD") for
computer networks, and the BBN HARK speech recognition software.  The Company's
T/10 IAD activities are now being primarily focused on a limited number of
reseller and strategic licensing opportunities and the future success of the
T/10 IAD is highly dependent on these opportunities.  The Company has
substantially reduced spending relating to the T/10 IAD from prior period
levels.

                                BBN CORPORATION
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

     During FY1995 and the first three quarters of FY1996, the Company has also
made significant investments in Internet-related services.  In support of its
Internet business strategy, the Company may make acquisitions or enter into
strategic alliances.  In June 1995, BBN and AT&T entered into a strategic
relationship under which BBN is to be the exclusive provider for a period of up
to three years of dedicated Internet access and managed network security
services to AT&T for resale to customers of AT&T's Business Communications
Services division in the United States.  In addition to certain other
termination provisions, AT&T may cancel the agreement in the event either BBN
or BBN Planet merges with, or becomes controlled by, another telecommunications
carrier or an on-line service provider, and has the right to terminate the
exclusivity obligation and to withhold other financial benefits in certain
other situations.  In July 1995, AT&T Venture Company, L.P., a venture
partnership with AT&T as the sole limited partner, invested $8.0 million in BBN
Planet.  As part of the recently announced reorganization, the Company and AT&T
Venture Company, L.P. are currently in discussion concerning the exchange of
AT&T Venture Company, L.P.'s investment in BBN Planet into common stock of BBN
Corporation (see Footnote B to the consolidated financial statements).

     The market for Internet services is rapidly expanding, and there are
considerable uncertainties as to how the market will develop.  The markets for
the Company's Internet services are highly competitive.  In general there are
no substantial barriers to entry to the Internet services market and the
Company expects that competition with its Internet activities will intensify in
the future.  The Company expects that all of the major on-line services and
telecommunications companies will compete fully in the Internet services
market, and that other new competitors, including large computer hardware,
software, media, and other technology and telecommunications companies, will
enter the Internet services market, resulting in even greater competition for
the Company's services and significant pricing pressure, which may impact the
Company's operating results.

     The Company expects continued revenue growth from its Internet-related
activities for the remainder of FY1996.  An increasing percentage of the
Company's revenue is derived from Internet-related services and products, and
the Company expects that the success of its Internet-related efforts will
depend upon a number of factors, including the development and expansion of the
market for Internet access services and products, and of the networks which
comprise the Internet; the ability of the Company to continue and expand its
current relationships with AT&T and AOL; the capacity, reliability, cost, and
security of it's network infrastructure; its ability to finance the expansion
of its network infrastructure; its ability to develop price competitive
services that meet changing customer requirements; its ability on a timely
basis to attract and retain additional highly qualified management, technical,
marketing, and sales personnel; and its ability to manage its growth.  In
addition, the Company may need to raise additional funds through public or
private debt or equity financings in order to implement its strategy.  There
can be no assurance that any such funding will be available, or of the terms or
timing of any such funding.

                                BBN CORPORATION
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

     The Company's traditional commercial products, consisting principally of
minicomputer-based data analysis software and X.25 network systems, have
reached maturity in their respective life cycles, and the Company has
discontinued sales of most of its traditional X.25 systems and products and has
substantially eliminated its development effort, and significantly reduced its
selling effort, related to the systems business as a whole.  The Company
believes that sales of these mature products will continue to decline.  In
response, the Company has developed desktop versions of certain RS/Series
software products, and in FY1993 the Company introduced Cornerstone software, a
desktop-based data analysis and visualization software tool.  Sales of
Cornerstone software to date have been substantially below expectations.  Based
upon the rights to a technology acquired from IBM during FY1995, BBN Domain is
developing software designed for manufacturing process optimization.  The
Company has refocused its traditional software activities on networked process
optimization and now targets customers principally in the pharmaceutical and
manufacturing industries.  In connection with this effort, BBN Domain recorded
a charge to operations in the quarter ended September 30, 1995 of $1.7 million
(see Footnote D to the consolidated financial statements).

     The Company believes that BBN Domain's performance will depend primarily
on the timely development and market acceptance of its pharmaceutical industry
software products and its new manufacturing process optimization methodology,
along with continued acceptance of its data analysis software products.

     For the three months ended March 31, 1996, the Company reported an
operating loss of $30.2 million, which includes a $20.7 million charge to
writeoff goodwill and certain other costs and employee related expenses in
connection with its announced reorganization; the operating loss for the
comparable quarter of FY1995 was $5.6 million.  For the nine months ended March
31, 1996, the operating loss was $51.0 million, which includes the $20.7
million charge, compared to $12.2 million for the comparable period in FY1995.
The operating losses reflect continued investment in Internet-related
activities, including network infrastructure, sales and marketing activities,
and the development of new value-added Internet services.  The Company is
accelerating the expansion of its national backbone network for its Internet
operations in order to meet increasing demand.  Results for the three and nine-
month periods ended March 31, 1996 also reflect operating losses at BBN Domain,
the write-off of goodwill and other costs, operating losses at BBN HARK and 
lower profitability at Systems and Technologies.

     The net loss for the three and nine-month periods ended March 31, 1996 was
$29.1 million and $45.7 million, respectively, compared to net income of $74.5
million and $70.7 million, respectively, for the three and nine-month periods
ended March 31, 1995.  Net income for the FY1995 periods includes a pre-tax
gain of $105.1 million from the sale of the assets of LightStream Corporation
in January 1995.

     The Company expects to report continued operating losses for the remainder
of FY1996 primarily as a result of its ongoing investment in Internet-related
activities.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

[Underline]Revenue[End-Underline]
     Revenue for the three months ended March 31, 1996 increased $19.4 million
to $71.4 million, compared to $52.0 million for the comparable three months
ended March 31, 1995.  The increase relates primarily to the Company's Internet
activities which reported FY1996 third quarter revenue of $20.6 million
compared to $4.1 million for the corresponding prior year period; approximately
one-half of the increase relates to the AOL network management contract.

     Revenue for the nine months ended March 31, 1996 increased $40.8 million
to $195.7 million compared to $154.9 million for the comparable nine months
ended March 31, 1995.  Revenue in the prior year period included $8.4 million
associated with LightStream.  Revenue from the Company's Internet activities
increased $37.6 million; approximately one-half of the increase relates to the
AOL network management contract.  Revenue from BBN Systems and Technologies'
collaborative systems and from BBN Domain's data analysis software activities
also increased.

[Underline]Cost of Sales[End-Underline]
     Cost of services and products as a percentage of revenue for the three and
nine months ended March 31, 1996 was 70% and 68%, respectively, compared to 64%
and 62%, respectively, for the comparable prior year periods.  The increase in
the cost of sales percentages is principally related to lower margins on
increased Internet services revenue.

[Underline]Research and Development Expenses[End-Underline]
     A significant portion of the Company's current internally funded research
and development spending is related to efforts by BBN Domain.  Research and
development costs were relatively unchanged for the three months ended March
31, 1996 compared to the corresponding prior year period, reflecting decreased
spending at BBN Domain, partially offset by increased spending for Internet
activities projects.  Research and development costs increased $1.3 million
during the nine months ended March 31, 1996 compared to the prior year period.
Research and development expenses in the prior year nine-month period included
$3.9 million associated with LightStream.  Excluding LightStream, the increase
for the nine-month period was primarily in the Company's Internet activities.

[Underline]Selling, General and Administrative Expenses[End-Underline]
     Selling, general, and administrative expenses for the three and nine
months ended March 31, 1996 increased $6.3 million and $22.6 million,
respectively, from the comparable FY1995 periods.  Selling, general and
administrative expenses in the FY1995 nine-month period included $2.8 million
associated with LightStream.  Excluding LightStream in the FY1995 nine-month
period, the increases for both the three and nine month periods ended March 31,
1996 primarily reflect the Company's continued investment in the sales and
marketing efforts of the Company's Internet-related activities.  The increase
in the current period also includes $1.4 million of the charge recorded in the
nine-month period at BBN Domain to provide for employee related costs
associated with the decision to refocus its business (see Footnote D to the
consolidated financial statements).

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

[Underline]Goodwill Write-Off and Other Charges[End-Underline]
     In the third quarter of FY1996, the Company recorded a charge of
approximately $20.7 million to write off goodwill previously recorded in
connection with the acquisitions of BARRNet and SURAnet in August 1994 and
March 1995, respectively, and certain other costs and employee related expenses
in connection with its announced reorganization (see Footnotes B and C to the
consolidated financial statements).  The goodwill write-off was precipitated by
a business evaluation, which included a review of the Company's current
Internet-related business in comparison to expectations established at the time
of the acquisitions.  The Internet services market has changed significantly
and is continuing to develop rapidly, including the emergence of new
competition, increasing downward pressure on prices, a more capital intensive
infrastructure, rapidly changing technology, and frequent new product and
service introductions (see Footnotes B and C to the consolidated financial
statements).

[Underline]Interest[End-Underline]
     Interest income for the three and nine months ended March 31, 1996
decreased $0.5 million and increased $0.9 million, respectively, from the
comparable FY1995 periods.  The changes are directly related to the level of
invested cash balances.

[Underline]Other Income[End-Underline]
     Other income for the three months ended March 31, 1995 primarily includes
a $105.3 million gain, before taxes and minority interest, relating to the sale
of substantially all the assets of LightStream on January 11, 1995.

     Other income for the nine months ended March 31, 1995 includes the
LightStream gain, and amounts arising from contracts which were substantially
completed in prior years.  In December 1994, the Company settled a claim with
the U.S. government for approximately $0.7 million, resulting in a reduction in
liabilities of approximately $2.6 million which is included in other income for
the nine months ended March 31, 1995.  Other income for the nine months ended
March 31, 1995 also includes approximately $0.9 million resulting from lower
than expected costs associated with a previously divested contract.


[Underline]Income Taxes[End-Underline]
     The income tax benefit recorded in the nine-month period ended March 31,
1996 was approximately 10% and represents the effective rate at which the
Company can utilize its FY1996 operating loss, up to a specified maximum, to
recover taxes paid in the prior year; the remaining income tax benefit at March
31, 1996 is approximately $1.3 million.  The tax provision in the nine-month
period of FY1995 related primarily to the gain on the sale of Lightstream.

[Underline]Liquidity and Capital Resources[End-Underline]
     As of March 31, 1996, the Company had cash and cash equivalents and short
term investments amounting to $72.5 million, a decrease of $38.3 million from
June 30, 1995.  The decrease includes $22.9 million used by operations, $19.4
million used for capital expenditures, and $2.8 million of payments to the
minority shareholder in connection with the LightStream sale.  These decreases
were partially offset by $8.0 million received from AT&T Venture Company, L.P.
as an investment in BBN Planet. (See Footnote B to the consolidated financial
statements).  Changes in cash balances due to fluctuation in foreign exchange
rates were insignificant.

                                BBN CORPORATION
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                  (continued)

     Working capital, excluding cash and cash equivalents and short-term
investments, increased $6.2 million as a result of an increased level of
receivables and a $5.3 million tax refund due which is included in other
current assets.

     The balance of accrued restructuring costs of $7.7 million relates to the
Company's FY1993 downsizing and represents excess facilities costs under long-
term leases in excess of sublease income.  These costs are anticipated to be
liquidated in varying amounts through 2005.  The Company has sublet or assigned
the majority of its excess facilities under agreements with terms expiring
between 1998 and 2005.

     In April 1996, the Company entered into a capital lease agreement to
finance certain equipment acquisitions.  The total cost of the assets to be
covered by the lease is limited to $15.0 million.  The agreement includes a
saleand leaseback of assets purchased during the nine months ended March 31,
1996 of approximately $7.0 million, and an $8.0 million commitment for assets
to be purchased through September 30, 1996.

     The Company's capital requirements which include the costs for building
its Internet network infrastructure, for further investments in working
capital, other capital equipment and selling and marketing infrastructure, and
for pursuing potential investments, acquisitions and other expansion
opportunities are expected to be significant.  The Company believes that its
existing cash balances are adequate to meet its requirements at least through
the remainder of the current fiscal year.  The Company may need to raise
additional funds through public or private debt or equity financings in order
to implement its strategy.  There can be no assurance that any such funding
will be available, or of the terms or timing of any such funding.  Currently,
the Company does not have any bank lines of credit.
