                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


FY1994 COMPARED TO FY1993
- - -------------------------

INTRODUCTION
        In FY1994, the company consisted of three operating units, the Systems
and Technologies Division, BBN Software Products Corporation and LightStream
Corporation.  The Systems and Technologies Division ("Systems and
Technologies") includes internetworking services and products, collaborative
systems and acoustic technologies.  BBN Software Products Corporation
("Software Products"), a wholly-owned subsidiary of the company, develops,
markets and supports data analysis software products designed primarily for
manufacturing, engineering and health industry applications. LightStream
Corporation ("LightStream"), an 80%-owned subsidiary of the company, develops,
markets and supports networking products based on Asynchronous Transfer Mode
("ATM") technology.

SUMMARY
        For the year ended June 30, 1994, the company had a loss of $7.8
million, or $.48 per share, on revenue of $196.1 million, compared to a loss of
$32.3 million, or $2.05 per share, on revenue of $233.4 million for FY1993.
Results for the prior year included a restructuring charge of $20.5 million, or
$1.30 per share, and a gain of $3.2 million, or $.20 per share, resulting from
the sale of the company's Advanced Simulation business in April 1993.  The
reduction in revenue from the prior year reflects the sale of the Advanced
Simulation business and reduced defense communications systems revenue.  The
company's losses continue to reflect significant expenditures on its LightStream
ATM switch, T/10[TM] Integrated Access Device and BBN/Cornerstone[TM] software
while revenue from these new products remains financially insignificant.  These
losses were partially offset by operating income at Systems and Technologies.

        The company's objective is to achieve revenue growth in FY1995 and a
return to profitability during the second half of the fiscal year.  However,
this outlook is strongly dependent upon achieving a significant increase in new
product and services revenue.  There can be no assurance that such an increase
will be realized.  The outlook could also be affected by further expenditures on
commercial business opportunities available to the company.

        The company's overall strategy is to capitalize upon its technical
expertise and problem solving experience in the internetworking, data analysis,
collaborative and acoustic systems areas.  This strategy is being implemented
through five distinct and complementary business units.  In addition to the
established Systems and Technologies and Software Products operating units, the
company in the past year has organized three early stage companies.  LightStream
Corporation was organized in October 1993 to develop and market ATM products,
and in July 1994 the company formed BBN HARK Systems Corporation to develop and
market speech recognition products.  Computer speech recognition is an emerging
market, and the company intends to increase its sales and marketing investment
in this area.  The company is also investing in the expansion of its Internet
services business by organizing a new subsidiary, BBN Internet Services
Corporation, which is being established to provide Internet services on a
worldwide basis.  The company's anticipated revenue growth is dependent upon its
ability to continue to recruit entrepreneurial marketing and sales leadership,
develop a support infrastructure and establish productive customer
relationships, particularly in the commercial marketplace.  The implementation
of this strategy will require significant investment in sales and marketing.

        On August 19, 1994, BBN Internet Services Corporation acquired, from
Stanford University, the Bay Area Regional Research Network ("BARRNET"), a
leading provider of Internet services in the San Francisco Bay area, for
approximately $6.5 million consisting principally of $2.0 million of cash,
270,270 shares of BBN's common stock and 200,000 shares of BBN Internet Services
Corporation's common stock.  The company may accelerate its plans to invest in
expanding its Internet services activities. Such investments may include
additional acquisitions and increased spending which could adversely affect the
company's financial results for FY1995.

REVENUE

        Revenue decreased $37.3 million, or 16%, in FY1994 compared to FY1993. 
The reduction reflects approximately $25.3 million in FY1993 revenue provided
by the company's former simulation unit as well as

                                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


declines in the company's defense communications systems business and lower 
revenue in FY1994 from its mature X.25 network products and RS/Series[TM] 
software.

        The company, like other companies doing business with the Department of
Defense, has been adversely affected by reduced defense spending and expects
this general decline and attendant increased competition within the defense
industry to continue over the next several years. Uncertainty continues to exist
on the size and scope of reductions in future defense budgets and their impact
on the company's defense-related business.  Further, there is the possibility
that funding limitations could result in a 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 years, and this trend
is expected to continue at least through FY1995, particularly in the defense
communications systems and acoustic and sensor systems areas.

        In FY1991, the Defense Information Systems Agency awarded the company a
one-year contract in support of the Defense Data Network, with up to four
one-year optional extensions.  The company is currently performing under the
third option year of the contract, valued at approximately $20 million, which
will continue the company's existing activities through October 1994.  The
company now expects to be awarded the fourth option year of the contract, valued
at approximately $15 million, which will continue these activities through
October 1995.  There can be no assurance that this activity will continue beyond
October 1995.  Approximately $21 million and $27 million of revenue has been
recorded under the contract in FY1994 and FY1993, respectively.

        The company conducts its commercial businesses in environments
characterized by intense competition, shortened product cycles and rapid
technological change, which require significant research and development
expenditures to develop new products which address emerging market requirements
and to improve its existing products.  The company's traditional commercial
businesses, consisting principally of X.25 network products and RS/Series data
analysis software products, continue to experience substantially lower revenue. 
In recent years, the company has been investing heavily in the development of
new products, primarily the LightStream ATM switch and the T/10 Integrated
Access Device in the networking area and BBN/Cornerstone data analysis software.

        Several important trends have adversely affected the company's X.25
network systems business, including the growth of desktop computing, the
widespread installation of local area networks, increased transmission circuit
speed and improved circuit quality.  These trends have led to market
requirements for networking technologies such as routers.  The company's X.25
network systems business has experienced significantly lower revenue for several
years.  The company has discontinued certain of its traditional X.25 products
and has substantially reduced its development and selling efforts relating to
this business.

        Sales of the LightStream 2010 ATM switch, released in October 1993, have
not been financially significant. Further, the emerging market for ATM products
is very competitive, particularly from communications companies with marketing,
distribution and resources more extensive than those available to LightStream. 
Accordingly, the success of LightStream's 2020 ATM switch, due to be released in
the fall of 1994, will depend upon the timely development of the ATM market, and
in particular the ATM enterprise switch market which is the market segment
targeted by LightStream, the technological superiority of LightStream's
products, their cost competitiveness and the development of strategic alliances
and distribution channels.  In the event these conditions are not achieved on a
timely basis, the company's financial results will be adversely impacted.

        For several years, the company has been developing the T/10 Integrated
Access Device designed to help customers consolidate traffic over a single
enterprise network. Development delays and limited functionality have
unfavorably affected the company's ability to generate sales, and revenue to
date from the T/10 has not been financially significant.  During FY1994,
spending relating to the T/10 business was significantly reduced from prior year
levels.  Effective April 1, 1994, the T/10 activities were merged into Systems
and Technologies.  The T/10 effort is now being primarily focused on a few
reseller opportunities, and accordingly, the future success of the T/10 is
highly dependent upon the timely development of these opportunities.

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

        The company's data analysis software products business has been affected
by the growth of distributed processing and the associated use of personal
computers, workstations, and other desktop computers.  Most of the company's
data analysis software products, primarily the RS/Series software, currently
operate on minicomputer systems.  As demand for minicomputer-based software
declines, the company is experiencing substantially lower RS/Series software
revenue and downward pressure on prices.

        In response to the trend toward desktop computing, Software Products
introduced its BBN/Cornerstone software during the fourth quarter of FY1993. 
BBN/Cornerstone software is the first of a new series of data analysis software
products specifically designed for use on desktop computers in a client/server
environment.  The initial release of BBN/Cornerstone software operates on
Unix-based workstations, utilizing a number of established graphical user
interfaces.  Planned subsequent releases in the second half of FY1995 will
operate on personal computers.  The company is also working to more tightly
integrate BBN/Cornerstone and its RS/Series software products.  To date, sales
of BBN/Cornerstone have been financially insignificant. Software Products also
develops health industry applications software, including BBN/Clintrial[TM]
software used to support clinical trials.  In FY1994, BBN/ClinTRACE[TM], an
adverse events tracking system, was also introduced to serve this market.

COST OF SALES
        Cost of services and products as a percentage of revenue was 66% in
FY1994 compared to 64% in FY1993.  The increase in the cost of sales percentage
is principally due to a lower proportion of products revenue primarily as a
result of the sale of the Advanced Simulation business and to competitive price
pressures in the company's defense-related business.  Services revenue, which
typically contributes lower margins than products sales, represented 85% of
total revenue in FY1994 compared to 75% in FY1993.

RESEARCH AND DEVELOPMENT EXPENSES
        The majority of the company's internally funded research and development
spending is currently directed principally toward the LightStream ATM products,
the T/10 and BBN/Cornerstone.  Research and development expenses in FY1994 were
$22.5 million compared to $34.0 million in FY1993.  The reduction in FY1994
reflects lower spending for the T/10 program and BBN/Cornerstone as well as the
sale of the Advanced Simulation business in FY1993.  The company's continued
significant investment in research and development is dependent upon the timely
market acceptance of its new products.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
        Selling, general and administrative expenses decreased $10.9 million in
FY1994 from FY1993 primarily as a result of lower selling expenses in the
defense communications systems business and at Software Products as well as the
cost reduction actions taken in FY1993.

INTEREST
        Interest income increased $.7 million in FY1994 from FY1993 primarily in
connection with a state tax refund.

OTHER INCOME
        Other income decreased $2.2 million in FY1994 from FY1993 primarily
reflecting the $3.2 million gain in FY1993 resulting from the sale of the
company's Advanced Simulation business and $.9 million in FY1994 resulting from
lower than expected costs associated with a previously divested contract.

LIQUIDITY AND CAPITAL RESOURCES
        As of June 30, 1994, the company's cash and temporary investments,
which consisted primarily of money market funds and short term U.S. government
securities, were $67.1 million, an increase of $10.3 million from June 30,
1993.  The increase is primarily attributable to the investment by UB Networks,
Inc. in LightStream and cash proceeds from the sale of stock options.

        As a result of the FY1993 downsizing, the company has unutilized space
which it is in the process of subleasing.

        In December 1992, the Board of Directors of the company voted to suspend
the semiannual dividend of three cents per share.  The company currently has no
plans to reinstate a dividend.

MANAGEMENT CHANGES
        In January 1994, George H. Conrades became president and chief executive
officer, succeeding Stephen R. Levy who remains as chairman of the board.

Mr. Conrades, 55, a former senior vice president of IBM who spent more
than thirty years with that company, also became a director. In January 1994,
LightStream named Jonathan C. Crane its president and chief executive officer
and in June 1994, John T. Kish joined Software Products as its president and
chief executive officer.  In July 1994, Frank E. Heart, 65, president of the
company's Systems and Technologies Division, retired after 28 years with the
company.  Searches are currently in process for a chief executive of both the
newly formed speech and Internet subsidiaries, and the company is also actively
recruiting for a number of marketing and sales positions throughout the
company.

FY1993 COMPARED TO FY1992
- - -------------------------

        The management's discussion and analysis which follows reflects the
company's organization in effect prior to FY1994.  During FY1993 and FY1992, the
company was organized in three divisions: BBN Systems and Technologies, which
includes internetworking services, collaborative and acoustic technologies, and
simulation systems; BBN Communications, which concentrates on defense
communications systems and X.25 network products, and also included the
company's ATM and T/10 activities; and BBN Software Products, which develops,
markets and supports data analysis software products designed primarily for
manufacturing, engineering and health industry applications.  Effective July 1,
1993, BBN Systems and Technologies assumed responsibility for all of the
company's X.25 network systems and defense communications businesses and
performs virtually all government contracts for the company.

SUMMARY
        The company reported a loss of $32.3 million, or $2.05 per share, on
revenue of $233.5 million in FY1993 compared to net income of $7.8 million, or
$.46 per share, on revenue of $258.0 million in FY1992.  Results for FY1993
included a restructuring charge of $20.5 million, or $1.30 per share, in
connection with downsizing and staff reductions, and a gain of $3.2 million, or
$.20 per share, from the sale of the company's Advanced Simulation business. 
Results for FY1992 included an extraordinary gain of $3.6 million, or $.22 per
share, from the purchase and early retirement of $9.8 million (face value) of
the company's 6% convertible subordinated debentures.
        The company reported a loss from operations (excluding the $20.5 million
restructuring charge) of $11.9 million in FY1993 compared to income from
operations of $6.9 million in FY1992.  Operating results for FY1993 reflected
significant losses at the former BBN Communications Division, arising from the
high level of investment the company was expending for network products (the
T/10 Integrated Access Device and the ATM switch), compounded by significant
revenue declines in its defense communications systems business and lower demand
for its mature X.25 network systems and data analysis software products.

        Revenue decreased $24.5 million, or 10%, in FY1993 compared to FY1992. 
The decrease primarily reflected significantly reduced defense communications
systems revenue and to a lesser extent lower revenue from the company's mature
X.25 network systems and data analysis software products.  These declines were
partially offset by a revenue increase in the areas of advanced internetworking
and acoustic systems.

COST OF SALES
        Cost of services and products as a percentage of revenue was 64% in
FY1993 compared to 57% in FY1992.  The increase in the cost of sales percentage
primarily related to competitive price pressures in the company's
defense-related business, declines in the company's X.25 network systems and
data analysis software products businesses and inventory provisions.  The lower
cost of sales percentage for FY1992 also included a $2.9 million benefit
relating the company's finalization of pricing in FY1992 for the Mobile
Subscriber Equipment program which was substantially completed FY1993.

RESEARCH AND DEVELOPMENT EXPENSES
        Research and development expenses were $34.0 million in FY1993 compared
to $33.7 million in FY1992.  A significant portion of the company's internally 
funded  research and development spending in FY1993 was directed toward the 
LightStream 2010, T/10 Integrated Access Device, BBN/Cornerstone software, 
and the

FINANCIAL CONDITION AND RESULTS OF OPERATIONS



GT-200 Computer Image Generator in the Advanced Simulation business.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
        Selling, general and administrative expenses decreased $7.6 million in
FY1993 compared to FY1992 which primarily reflected lower sales and marketing
expenses at Software Products, lower sales expenses in the Advanced Simulation
business and reduced administrative expenses caused mainly by reduction in
personnel.

INTEREST
        Interest income decreased $1.0 million in FY1993 compared to FY1992
primarily attributable to a decline in short-term interest rates in FY1993.

OTHER INCOME
        In the fourth quarter of FY1993, the company sold the fixed assets,
inventory and technology of its Advanced Simulation business to a subsidiary of
Loral Corporation for $6.0 million in cash.  In connection with the sale, the
buyer assumed the lease obligation for the company's facility in Bellevue,
Washington and leased from the company certain space occupied by the Advanced
Simulation business in Massachusetts.  More than 100 employees of the Advanced
Simulation business moved to the buyer.  The company retained accounts
receivable of approximately $7.2 million associated with the Advanced Simulation
business which have been collected.  In FY1993, approximately $25.3 million of
the company's revenue related to this business.  Results for the fourth quarter
of FY1993 included a gain of $3.2 million in connection with the sale.

INCOME TAXES
        In FY1993, the company adopted Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").  The adoption 
of SFAS 109 did not have a material impact on the company's consolidated 
financial position and results of operations.

RESTRUCTURING
        The company recorded a restructuring charge of $20.5 million in the
second quarter of FY1993 primarily associated with employee severance and
related facilities costs.  Approximately one-half of the second quarter
restructuring charge related to the estimated cost of unutilized space.  The
remainder of the restructuring charge reflected the company's downsizing and
cost reduction efforts at its former BBN Communications Division, the
consolidation of the company's defense business within the BBN Systems and
Technologies Division, and the elimination of substantially all of the company's
internal manufacturing capability.
        In FY1993, the company consolidated a number of senior management
positions including those of chief executive officer and chief operating
officer.  The company also made management changes at its former BBN
Communications Division and BBN Systems and Technologies Division, including
replacing the presidents of those divisions.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- - ------------------------------------------

PRINCIPLES OF CONSOLIDATION
        The consolidated financial statements include the accounts of the
company and its majority- and wholly-owned subsidiaries.  All significant
intercompany transactions and balances have been eliminated. Certain amounts
reported in prior years have been reclassified to be consistent with the current
year's presentation.

REVENUE RECOGNITION
        Revenue from cost-reimbursement contracts, principally consisting of
services, is recorded as costs are incurred and fees are earned. Revenue from
fixed-price contracts, relating to services and certain systems, is recognized
using the percentage-of-completion method of accounting in the proportion that
costs incurred bear to total estimated costs at completion. Losses, if any, are
provided for in the period in which the loss is determined.  Products revenue is
recognized at the time of shipment.

GAIN ON ISSUANCE OF STOCK BY SUBSIDIARIES
        At the time a subsidiary sells its stock to unrelated parties at a price
in excess of its book value, the company's net investment in that subsidiary
increases.  If at that time the subsidiary is an operating entity and not
engaged principally in research and development, the company records the
increase as a gain in its consolidated statements of operations.  Otherwise, the
company records the increase as an equity transaction which is reflected in the
consolidated statements of shareholders' equity as a gain on the sale of
subsidiary stock.

CASH AND TEMPORARY INVESTMENTS
        For purposes of the consolidated statements of cash flows, cash includes
all cash and temporary investments, generally with original maturities of three
months or less, carried at original cost plus accrued interest, which
approximates market value.  At June 30, 1994 and 1993, temporary investments
consisted principally of money market funds (invested in U.S. government
securities and other highly rated financial instruments) and U.S. government
securities.

INVENTORIES
        Inventories are stated at the lower of cost (using the first-in,
first-out method) or market.

PROPERTY, PLANT AND EQUIPMENT
        Property, plant and equipment is stated at cost less accumulated
depreciation and amortization.  Depreciation is computed over the assets'
estimated useful lives using the straight-line method.  Leasehold improvements
are amortized over the shorter of the lease period or their estimated useful
lives using the straight-line method. Maintenance and repairs are charged to
expense as incurred; improvements are capitalized.  Beginning in fiscal year
1994, the company's policy is to remove the amounts related to fully-depreciated
assets from its accounting records.

SOFTWARE COSTS
        The company capitalizes purchased software technology and certain
internally developed computer software costs to be sold or otherwise marketed to
customers.  Costs incurred internally after establishing technological
feasibility and before general release of a computer software product are
amortized over 3 years.  Costs incurred for purchased software technology
are amortized over periods up to 7 years.

FOREIGN CURRENCY TRANSLATION
        The assets and liabilities of the company's foreign subsidiaries are
translated at year-end exchange rates, and the related statements of operations
are translated at average exchange rates for the year.  Translation gains and
losses are accumulated as a separate component of shareholders' equity.
Transaction gains and losses, which are immaterial, are included in "Other 
income (expense), net" in the consolidated statements of operations.

INCOME TAXES
        A deferred tax asset or liability is determined based on both the
difference between the financial statement and tax basis of assets and
liabilities as measured by the enacted tax rates which will be in effect when
these differences reverse, and the future tax benefit to be derived from tax
loss and tax credit carryforwards.  A valuation allowance has been established
to reflect the likelihood of realization of deferred tax assets.

NET INCOME (LOSS) PER SHARE
        Net income (loss) per share is calculated based on the weighted average
number of common and common equivalent shares outstanding.  Common equivalent
shares result from the assumed exercise of dilutive stock options.  The
company's 6% convertible subordinated debentures are not considered common stock
equivalents for per-share calculations.  Common equivalent shares were
anti-dilutive in fiscal years 1994 and 1993 and, therefore, were excluded from
the net loss per-share calculation.

Unbilled amounts represent receivables for work performed for which billings
had not been presented to the customers or which were not yet contractually
billable. Unbilled receivables, except for retentions, are generally billed
and collected within one year. Retentions amounted to $3,662,000 and
$6,078,000 at June 30, 1994 and 1993, respectively.  A significant portion of
the retentions at June 30, 1994 is anticipated to be collected after fiscal
year 1995.

CONVERTIBLE SUBORDINATED DEBENTURES
- - -----------------------------------
        The 6% convertible subordinated debentures due 2012 (the "debentures") 
may be converted into the company's common stock at a price of $30.00 per 
share any time prior to maturity. The company has reserved 2,823,000 shares 
of its authorized but unissued common stock to be available for the conversion 
of the debentures. The debentures are unsecured obligations of the company and 
are subordinated in right of payment to all of the company's senior 
indebtedness. Debt issuance costs are being amortized over the term of the 
debentures. The unamortized balance at June 30, 1994 of $1,152,000 is 
included in "Other assets" in the consolidated balance sheets. The fair 
market value of the debentures, which is based on quoted market prices, 
was $50,722,000 at June 30, 1994.

        Beginning April 1, 1998, the company is required to contribute to a
sinking fund with annual payments equal to 5% of the aggregate principal amount
issued. The sinking fund is calculated to retire 70% of the original debentures
prior to maturity. The debentures are redeemable at the company's option.
However, redemption of the debentures prior to April 1, 1998 requires payment of
a premium.  None of the debentures have been redeemed.

        In August 1990, the Board of Directors authorized the company to expend
from time to time in open market or negotiated transactions up to $15,000,000
for the purchase at a discount of its debentures.  Any debenture purchased may
be utilized to satisfy sinking fund requirements.  In fiscal year 1992,
$6,190,000 was expended under this authorization for the purchase and early
retirement of $9,845,000 (face value) of debentures resulting in an
extraordinary gain of $3,648,000. No income taxes were applied to the
extraordinary gain primarily due to the availability of net operating loss
carryforwards.  As of June 30, 1994, $7,027,000 has been expended to date under
this authorization for the purchase and early retirement of $11,190,000 (face
value) of debentures.  By utilizing the $11,190,000 of debentures purchased by
the company, contributions to satisfy the annual sinking fund requirements can
be deferred until April 1, 2000.

        The company leases a majority of its facilities under long-term
operating leases which generally provide for renewal options and options to
purchase the leased property.  Although in most cases such leases will be
renewed or replaced by other leases in the normal course of business,
consolidation of certain of the company's leased facilities has resulted in
diminished need for such renewals and replacements.  The company is actively
pursuing subletting certain of its leased facilities.

        Total rent expenditures, net of sublet income, under all operating
leases and rental agreements amounted to $16,980,000, $18,180,000 and
$18,560,000 in fiscal years 1994, 1993 and 1992, respectively.

COMMON STOCK
- - ------------

        The Board of Directors authorized the purchase of up to an aggregate of
2,000,000 shares of the company's common stock under which approximately 60,000
additional shares may be purchased.  In fiscal years 1993 and 1992, the company
purchased 178,500 shares and 2,112,000 shares, respectively, for $723,000 and
$10,541,000, respectively.  The fiscal year 1992 purchase included 988,000
shares purchased under a separately authorized transaction at a small discount
from the market price at the time of the transaction. Approximately 4,920,000
shares costing approximately $35,400,000 have been purchased under the
repurchase program and the other separately authorized transactions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        In December 1993, in connection with his hiring, an executive officer of
the company made an investment of $212,500 in the company by purchasing from the
company 20,202 restricted shares of the company's common stock at a 15% discount
from the closing market price on the date of the transaction. The restricted
shares were treasury shares and were not registered under the Securities Act of
1933 and may not be sold, assigned, pledged, or otherwise transferred before the
lesser of two years or the filing of an effective registration statement under
the Act.

        The company has a Common Stock Rights Plan (the "plan") to protect the
interests of the company's shareholders.  Under the plan, holders of each share
of the company's common stock have the right to purchase one additional share of
common stock at $90 per share, subject to adjustment, exercisable under certain
defined conditions.  In the event that the rights become exercisable due to an
acquisition of the company or under certain other conditions, holders of the
rights would be entitled to purchase common stock of the surviving company
having a value of two times the exercise price of the rights.  The holder of a
right is not entitled to vote or receive dividends until the right is 
exercised. The rights are redeemable by action of the Board of Directors at 
$.01 per right. The company is not currently aware of any activities which 
would cause the rights to become exercisable.

EMPLOYEE BENEFIT PLANS

STOCK COMPENSATION PLANS

        Under the company's stock option plan, key employees may be granted
options enabling them to purchase shares of the company's common stock at a
price of not less than 50% of the fair market value of the common stock on the
date of grant.  All options granted in fiscal years 1994, 1993 and 1992 were at
fair market value on the dates of grant.  The plan provides that directors who
are not employees of the company receive a non-qualified option for 10,000
shares. The plan also provides for granting of other stock-based awards at the
discretion of the Board of Directors and for granting of incentive stock
options.  Options vest generally over four years and expire not more than ten
years from the dates of grant.  Options which are cancelled become available for
future grants.

The changes in stock options outstanding for the three years ended 
June 30, 1994 were as follows:

                                                                     Range of

include the 350,000 conditional options granted in fiscal year 1994.


        In fiscal year 1994, LightStream Corporation, the company's 80%-owned
subsidiary, adopted a stock option plan under which its employees may be granted
options enabling the purchase of up to 1,300,000 shares at the fair value of the
common stock on the date of grant.  Additionally, under a separate plan 300,000
shares of LightStream Corporation's common stock issued to BBN at the time
LightStream Corporation was formed are reserved for award to employees of BBN.
Options granted under both of these plans are only exercisable 90 days after the
closing of an initial public offering of LightStream Corporation's common 
stock. As of June 30, 1994, options to purchase 1,229,000 shares of LightStream
Corporation's common stock were outstanding.  As of June 30, 1994, LightStream

EMPLOYEE STOCK PURCHASE PLAN
        Under the company's 1983 Stock Purchase Plan, an aggregate of 3,600,000
shares of common stock were made available for purchase by employees who have
completed at least six months of continuous service in the employ of the
company, upon exercise of options granted semi-annually. The options are
exercisable six months after grant, at the lower of 85% of the fair market value
of the common stock at the beginning or the end of the six-month period, but in
no event for less than the company's net book value per share as of the end of
the quarter next preceding the exercise, through accumulation of payroll
deductions ranging from 2% to 10% of each participating employee's compensation,
as defined, but in no event more than $3,000 or 400 shares during any six-month
option period prior to June 30, 1994.  Effective July 1, 1994, the maximum
number of shares a participant may acquire in any six-month option period is
1,000 through the accumulation of payroll deductions which may not exceed
$12,500.
        Options were exercised to purchase 185,000, 283,000 and 330,000 shares
for a total of $1,519,000, $1,125,000 and $1,402,000 in fiscal years 1994, 1993
and 1992, respectively.  At June 30, 1994, 687,000 shares of authorized but
unissued common stock were reserved for future issuance under this plan.

RETIREMENT PLAN
        The company has a defined contribution retirement plan covering
substantially all of its domestic employees.  The company's contribution to the
plan is discretionary and is based on a percentage of employees' eligible
compensation, as defined.  Employees may also contribute to the plan.  The
company's total costs pursuant its retirement plan were $5,517,000, $6,515,000
and $6,535,000 in fiscal years 1994, 1993 and 1992, respectively. Effective July
1, 1994, the company adopted an amendment to its retirement plan which has been
qualified under Section 401(k) of the Internal Revenue Code. Eligible employees
are permitted to contribute to the plan through payroll deductions within the
statutory limitations and subject to any limitations included in the plan.  The
plan provides for matching contributions by the company up to a maximum of $500
per employee annually.

INCENTIVE COMPENSATION PLANS
        The company maintains incentive compensation plans for key employees,
including its executive management.  Awards under these plans are paid in
recognition of individual contribution to divisional or corporate performance as
determined by management or the Compensation and Stock Option Committee of the
Board of Directors.  Total costs pursuant to the company's incentive
compensation plans were $1,820,000, $510,000 and $460,000 in fiscal years 1994,
1993 and 1992, respectively.

RESEARCH AND DEVELOPMENT COSTS
- - ------------------------------
        The company performs research and development under contracts
principally with the U.S. government. Costs incurred under these contracts are
charged to "Cost of services" in the consolidated statements of operations as 
the related services revenue is recorded. Costs classified as "Research and
development expenses" in the consolidated statements of operations are costs
incurred under internally initiated programs, including independent research and
development as defined by government procurement regulations.

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.  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 have been made by the government
agencies.  Based upon government procurement regulations, under certain
circumstances a contractor violating or not complying with procurement
regulations can be subject to legal or administative proceedings, including
fines and penalties, as well as be suspended or debarred from contracting with
the government.  The company's policy has been and continues to be to conduct
its activities in compliance with all applicable rules and regulations.
        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.

employees in fiscal year 1993.

assets, inventory and technology of its Advanced Simulation business for
$6,000,000 in cash.  Results for the  fourth quarter of fiscal year 1993

from these contracts are offset against the effects of the foreign currency
translation.  At June 30, 1994 and 1993, the company had foreign exchange
contracts with maturities of three months or less to sell $750,000 and
$1,940,000, respectively, of foreign currencies.

FORMATION OF LIGHTSTREAM CORPORATION

LightStream Corporation, an ATM networking company, which is approximately 80%
owned by the company and a 20% minority interest owned by UB Networks, Inc.  The
company and UB Networks, Inc. contributed $15,000,000 and $5,000,000 in cash,
respectively, to fund the enterprise and each signed non-exclusive Original
Equipment Manufacturer agreements with LightStream Corporation under which both
the company and UB Networks, Inc. will distribute LightStream Corporation's
products.  The company recorded an increase of approximately $990,000 in both
its investment in LightStream Corporation and in its additional paid-in capital.

                                              REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and Board of Directors
Bolt Beranek and Newman Inc.
Cambridge, Massachusetts:

        We have audited the consolidated balance sheets of Bolt Beranek and
Newman Inc., at June 30, 1994 and 1993, and the related consolidated statements
of operations, shareholders' equity, and cash flows for each of the three years
in the period ended June 30, 1994. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

        We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Bolt
Beranek and Newman Inc., at June 30, 1994 and 1993, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended June 30, 1994, in conformity with generally accepted accounting
principles.
