ORBITAL SCIENCES CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
MARCH 31, 1999 AND 1998
(UNAUDITED)

BASIS OF PRESENTATION

In the opinion of management, the accompanying unaudited interim financial 
information reflects all adjustments, consisting of normal recurring
adjustments, necessary for a fair presentation thereof. Certain information and
footnote disclosure normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to instructions, rules and regulations prescribed by the
Securities and Exchange Commission. Although the company believes that the
disclosures provided are adequate to make the information presented not
misleading, these unaudited interim condensed consolidated financial statements
should be read in conjunction with the audited consolidated financial
statements and the footnotes thereto included in the company's Annual Report on
Form 10-K for the year ended December 31, 1998. Operating results for the
three-month period ended March 31, 1999 are not necessarily indicative of the
results expected for the full year.

Orbital Sciences Corporation, together with its subsidiaries, is hereafter
referred to as "Orbital" or the "company."

(1)    PREPARATION OF CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The preparation of condensed consolidated financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date
of the consolidated financial statements and the reported amounts of revenues
and expenses during the reporting period. Management periodically assesses and
evaluates the sufficiency and/or deficiency of estimated liabilities recorded
for various operational and business risks and uncertainties. Actual results
could differ from these estimates.

Certain reclassifications have been made to the 1998 financial statements to
conform to the 1999 financial statement presentation. All financial amounts are
stated in U.S. dollars unless otherwise indicated.

(2)    INVENTORIES

Inventories consist of components and raw materials inventory, work-in-process
inventory and finished goods inventory and are generally stated at the lower of
cost or net realizable value on a first-in, first-out or specific identification
basis, net of allowances for estimated obsolescence.



                                       5
<PAGE>   6

Components and raw materials are purchased to support future production efforts.
Work-in-process inventory consists primarily of (i) costs incurred under
long-term fixed-price contracts accounted for using the percentage-of-completion
method of accounting applied on a units of delivery basis, and (ii) partially
assembled commercial products, and generally includes direct production costs
and certain allocated indirect costs (including, in certain circumstances, an
allocation of general and administrative costs). Work-in-progress inventory has
been reduced by contractual progress payments received. Finished goods inventory
consists of fully assembled commercial products awaiting shipment.

(3)    DISAGGREGATED FINANCIAL INFORMATION

Industry Sector Information. Orbital's operations are organized into three
business sectors, which correspond to product and service types, different
markets served by the company's products and services, as well as the manner in
which these products and services are managed. Orbital's three business sectors
are space and ground infrastructure systems, satellite access products and
satellite services. Space and ground infrastructure systems include launch
vehicles, satellites and related space systems, electronics and sensor systems,
satellite ground systems and software and transportation management systems.
Satellite access products include satellite-based navigation, positioning and
communications products. Satellite services include satellite-based two-way
mobile data communications services, satellite-based remote imaging services,
satellite-based automotive information services and satellite-based voice
communications services.

The following table presents operating information for the three months ended
March 31, 1999 and 1998 and identifiable assets at March 31, 1999 and at
December 31, 1998 by business sector. Operating income (loss) is total revenues
less costs of goods sold, research and development expenses, selling, general
and administrative expenses, and amortization of goodwill. Identifiable assets
are those assets used in the operations of each business or investments in those
businesses. There were no significant sales or transfers between consolidated
sectors.

(4)    BUSINESS COMBINATIONS AND INVESTMENTS IN AND ADVANCES TO AFFILIATES

During the first quarter of 1999, the company's wholly owned Canadian
subsidiary, MacDonald, Dettwiler and Associates, Ltd. ("MDA"), increased its
ownership of a Canadian remote imaging company, Radarsat International ("RSI").
As a result of the transaction, at March 31, 1999 MDA held a majority and
controlling interest in RSI and, accordingly, consolidated RSI's results of
operations. The net purchase price, after cash acquired and foreign currency
adjustments, was approximately $1,000,000, which exceeded the fair value of the
net liabilities acquired by approximately $4,200,000. This excess is being
amortized on a straight-line basis over 20 years. The allocation of purchase
price to net liabilities acquired may be adjusted over the next year if
additional information becomes known about certain business assumptions used to
estimate the fair value of such net liabilities. In connection with the May
1999 acquisition of Spar Aerospace's space robotics business (see note 8), MDA
acquired the remaining outstanding shares of RSI, and accordingly, owns all
outstanding shares.

During the first three months of 1999, the company provided ORBCOMM Global, L.P.
$18,450,000 in additional capital and provided $2,000,000 of deferred invoicing
for work performed under a satellite and launch procurement contract during the
first three months of 1999.

(5)    INCOME TAXES

The company has recorded its interim consolidated income tax provision based on
an estimate of its full-year provision. The company's tax provision is for U.S.
Federal and state, and foreign income taxes. Estimated provisions recorded
during interim periods may be periodically revised, if necessary, to reflect
current estimates.

(6)    EARNINGS PER SHARE

Net income (loss) per common share is calculated using the weighted average
number of common shares outstanding during the periods. Net income (loss) per
common share, assuming dilution is calculated using the weighted average number
of common and common equivalent shares outstanding during the periods, plus the
effects of an assumed conversion of the company's convertible notes, after
giving effect to all net income adjustments that would result from the assumed
conversion.

In periods of net loss, the assumed conversion of convertible notes and 
exercise of stock options are anti-dilutive with respect to calculating net
income (loss) per share, and therefore are not considered in determining and
reporting net income (loss) per share. For the three months ended March 31,
1999, adjusted shares, assuming conversion of convertible notes and the
dilutive impact of outstanding stock options, would have been 41,751,171.

(8)    SUBSEQUENT EVENTS AND OTHER MATTERS

Business Combinations. In May 1999, the company acquired all the assets and
certain liabilities of the space robotics division of Toronto-based Spar
Aerospace Limited ("Spar") for approximately $43,000,000. The company paid
one-half of the purchase price in cash at closing and issued an unsecured 8%
note, due May 2000, for the remainder. The company will account for the
acquisition using the purchase method of accounting. The purchase price
exceeded the fair value of the net liabilities acquired by approximately
$48,000,000, which will be amortized on a straight-line basis over 20 years.
The allocation of purchase price to net liabilities acquired in the Spar
acquisition may be adjusted over the next year if additional information
becomes known about certain assumptions used to estimate the fair value of such
net liabilities.

In May 1999, the company entered into a $35,000,000 long-term license agreement
with the British Columbia provincial government whereby the company obtained the
exclusive rights to use certain government information databases. The company
intends to provide Internet-based services using these databases.

Litigation. During the first quarter of 1999, a number of class action lawsuits
were filed in federal court against the company, an officer and an
officer/director alleging violations of the federal securities laws during the
period from April 21, 1998 through February 16, 1999 and seeking monetary
damages. The company believes that these allegations are without merit and
intends to defend vigorously against such allegations.

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

OVERVIEW

Certain statements included in this discussion relating to future revenues,
expenses, growth rates, net income, new business, operational performance,
schedules, sources and uses of funds, "Year 2000" issues, the outcome of pending
litigation and the performance of our affiliates, Orbital Imaging Corporation
("ORBIMAGE"), ORBCOMM Global L.P. ("ORBCOMM") and CCI International NV ("CCI"),
are forward-looking statements that involve known and unknown risks,
uncertainties and other factors that may cause our actual results, performance,
achievements or investments to differ materially from any future results,
performance, achievements, or investments expressed or implied by such
forward-looking statements. Such factors include: general and economic business
conditions, launch results, product performance, risks associated with
government contracts, market acceptance of consumer products, the introduction
of products and services by competitors, risks associated with acquired
businesses, availability of required capital, our ability and the ability of our
customers and suppliers to assess and correct timely and accurately "Year 2000"
issues, market acceptance of new products and technologies, risks associated
with long-term contracts, the effects of pending or possible litigation or
government investigations and other factors more fully described in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Outlook: Issues and Uncertainties" included in our Annual Report on
Form 10-K for the year ended December 31, 1998.

Our products and services are grouped into three business sectors: space and
ground infrastructure systems, satellite access products and satellite
services. Space and ground infrastructure systems include launch vehicles,
satellites and related space systems, electronics and sensor systems, satellite
ground systems and software and transportation management systems. Our
satellite access products sector consists of satellite-based navigation,
positioning and communications products. Satellite services include the
following services conducted by our affiliates, ORBCOMM, ORBIMAGE, and CCI and
our subsidiaries Radarsat International ("RSI") and Orbital Navigation 
Corporation: satellite-based two-way mobile data communications services, 
remote imaging services, satellite-based automotive information services and 
satellite-based voice communications services. We do not control the 
operational and financial affairs of ORBCOMM, ORBIMAGE and CCI and consequently
their financial results are not consolidated with our results.

RECENT DEVELOPMENTS. In May 1999, we acquired all the assets and certain
liabilities of the space robotics division of Toronto-based Spar Aerospace
Limited for approximately $43,000,000 (the "Spar Acquisition"). We paid
approximately one-half of the purchase price in cash at closing and issued an
unsecured 8% note due May 2000 for the remainder. We will account for the
acquisition using the purchase method of accounting. The purchase price exceeded
the fair value of the net liabilities acquired by approximately $48,000,000,
which will be amortized on a straight-line basis over 20 years.



                                       11

In May 1999, we entered into a $35,000,000 long-term license agreement with the
British Columbia provincial government, whereby we obtained the exclusive rights
to use certain government information databases. We intend to provide
internet-based services using these databases.

During the first quarter of 1999, we increased our ownership of RSI. As a
result of the transaction, at March 31, 1999 we held a majority and controlling
interest in RSI and, accordingly, consolidated RSI's results of operations. The
net purchase price, after cash acquired and foreign currency adjustments, was
approximately $1,000,000, which exceeded the fair value of the net liabilities
acquired by approximately $4,200,000. This excess is being amortized on a
straight-line basis over 20 years. In connection with the Spar Acquisition, we
acquired additional shares of RSI, and accordingly, now own all outstanding
shares.

In March 1999, we signed a merger agreement with Lowrance Electronics, Inc.
("Lowrance"), a leading manufacturer of marine and recreational electronics
products using GPS-satellite navigation and sonar technology. Under the terms
of the merger, we will acquire all of the outstanding common stock of Lowrance
in exchange for shares of our common stock based on an acquisition price of
$27,500,000. The transaction is expected to close in the second half of 1999,
subject to regulatory approvals and Lowrance shareholder approval.

RESULTS OF OPERATIONS FOR THE THREE-MONTH PERIODS ENDED MARCH 31, 1999 AND 1998

REVENUES. Our consolidated revenues for the three-month periods ended March 31,
1999 and 1998 were $204,338,000 and $186,159,000, respectively.

Space and Ground Infrastructure Systems. Revenues from our space and ground
infrastructure systems sector totaled $175,248,000 and $159,555,000 for the
three months ended March 31, 1999 and 1998, respectively.

Revenues from our launch vehicles decreased to $43,472,000 in the first quarter
of 1999, from $46,040,000 in the first quarter of 1998. The decrease in revenues
in 1999 as compared to a year ago is primarily attributable to a decrease in
space launch vehicle revenues under existing contracts with affiliates.

For the three months ended March 31, 1999, satellite revenues increased to
$67,272,000 from $61,532,000 in the first quarter of 1998. The increase in
satellite sales is primarily due to additional revenues generated from a new
commercial geosynchronous satellite contract received in 1998.



                                       12
<PAGE>   13

Revenues from electronics and sensor systems and transportation management
systems increased to $35,813,000 for the three months ended March 31, 1999 from
$30,562,000 in the comparable 1998 period. This increase is largely due to the
December 1998 acquisition of the transportation management systems business of
Raytheon Company, which contributed revenues of $3,600,000 during the first
quarter of 1999.

Revenues from satellite ground systems and software increased to $28,691,000 in
the first quarter of 1999 as compared to $21,421,000 in the comparable 1998
quarter. The increase in 1999 revenues is due to work performed on orders
received in 1998 for a new satellite remote imaging system and for several other
satellite ground systems and system upgrades.

Revenues for the three months ended March 31, 1999 include sales to affiliates
of $32,207,000 as compared to first quarter 1998 sales to affiliates of
$43,601,000.

Satellite Access Products. Revenues from sales of satellite-based navigation,
positioning and communications products in the first quarter of 1999 were 
$26,172,000 as compared to $26,540,000 for the first quarter of 1998.

Satellite Services. Revenues for this sector include those generated by
ORBCOMM's domestic operation, ORBCOMM USA, L.P. ("ORBCOMM USA"), which we
consolidate, Orbital Navigation Corporation ("ORBNAV") and RSI. Revenues from
this sector are expected to increase throughout 1999.

GROSS PROFIT/COSTS OF GOODS SOLD. Costs of goods sold include the costs of
personnel, materials, subcontracts and overhead related to commercial products
and under various development and production contracts. Gross profit depends on
a number of factors, including the mix of contract types and costs incurred
thereon in relation to estimated costs. Our consolidated gross profit for the
first quarter of 1999 was $46,311,000 (23% of revenues) as compared to
$51,374,000 (28% of revenues) for the first quarter of 1998.

Space and Ground Infrastructure Systems. Gross profit margins from our space and
ground infrastructure systems totaled $38,466,000 (22% of sector revenues) and
$43,677,000 (27% of sector revenues) for the three months ended March 31, 1999
and 1998, respectively.

Gross profit margins from launch vehicles were 21% for the first quarter of 1999
as compared to 27% for the first quarter of 1998. The decrease in launch vehicle
gross margins in 1999 is primarily due to completing work on certain less
profitable space and suborbital launch vehicle contracts. Satellites contributed
gross margins of 20% during the first quarter of 1999 as compared to 28% during
the first quarter of 1998. The decrease is due to work performed on a large,
commercial geosynchronous satellite contract won in late 1998 that contains a
significant amount of lower margin, external subcontract effort. Revenues
recognized and subcontractor costs incurred on this contract during the first
quarter of 1999 also resulted in a significant increase in accounts receivable
and accounts payable since December 31, 1998; such receivables/payables 



                                       13
<PAGE>   14
 were collected/paid in April 1999. For the three months ended March 31, 1999
and 1998, electronics and sensor systems and transportation management systems
had consistent gross margins of 26% and 27%, respectively. Gross margins for
ground systems and software were 23% and 27% for each of the first quarters in
1999 and 1998, respectively. This decrease is due to an increase in lower
margin, subcontract work on several contracts and to lower margins on various
new international defense contracts.

Satellite Access Products. Gross margins for satellite access products were
generally consistent at 36% for the first quarter of 1999 and 35% for the first
quarter of 1998.

Satellite Services. Gross margins for this sector include those generated by
ORBCOMM USA, ORBNAV and RSI. This sector had a gross loss of $1,515,000 during
the first quarter of 1999, which was consistent with the gross loss of
$1,574,000 for the first quarter of 1998.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses represent
self-funded product development activities, and exclude direct customer-funded
development. Research and development expenses during the three-month periods
ended March 31, 1999 and 1998 were $10,002,000 (5% of revenues) and $8,565,000
(5% of revenues), respectively. Research and development expenses in both
quarters relate primarily to the development of new or improved satellite access
products, improved launch vehicles and new satellite initiatives.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses include the costs of marketing, advertising, promotional
and other selling expenses as well as the costs of the finance, legal,
administrative and general management functions of the company. Selling, general
and administrative expenses for the first quarters of 1999 and 1998 were
$29,813,000 (15% of revenues) and $27,484,000 (15% of revenues), respectively.

NET INVESTMENT INCOME (EXPENSE). Net investment income (expense) was
($1,088,000) and $260,000 for the three months ended March 31, 1999 and 1998,
respectively. Investment income reflects interest earnings on short-term
investments and realized gains and losses on investments, reduced by interest
expense of $1,765,000 and $169,000 on outstanding debt for the three months
ended March 31, 1999 and 1998, respectively. Interest expense has been reduced
by capitalized interest of $2,662,000 and $3,663,000 in 1999 and 1998,
respectively.

EQUITY IN EARNINGS (LOSSES) OF AFFILIATES AND NON-CONTROLLING INTERESTS IN
(EARNINGS) LOSSES OF CONSOLIDATED SUBSIDIARIES. Equity in earnings (losses) of
affiliates and non-controlling interests in (earnings) losses of consolidated
subsidiaries for the first quarters of 1999 and 1998 were ($17,121,000) and
($7,797,000), respectively. These amounts primarily represent (i) elimination of
proportionate profits or losses on sales of infrastructure products to ORBCOMM,
ORBIMAGE and CCI, (ii) our proportionate share of ORBCOMM's, ORBCOMM
International Partners L.P.'s and 

                                       14

ORBIMAGE's current period earnings and losses, (iii) 100% of CCI's losses for
the current period and (iv) non-controlling stockholders' proportionate share of
ORBCOMM USA, RSI's and Magellan's current period earnings and losses. The
increase in losses during the first quarter of 1999 is primarily due to
ORBCOMM's increased operational expenses relating to the roll-out of global
services, increased interest expense as interest expense was no longer
capitalized and increased system depreciation expenses as the satellites were
placed in service in late 1998. Additionally, ORBCOMM's revenues were less than
projected, in part due to a longer than anticipated sales order/installation
cycle. We expect equity in losses of affiliates in 1999 to be significantly
higher than 1998, primarily because we expect ORBCOMM to continue to incur
losses throughout 1999.

PROVISION FOR INCOME TAXES. We recorded an income tax provision of $1,298,000
and $1,083,000 for the three-month periods ended March 31, 1999 and 1998,
respectively. The provision in both periods was entirely due to foreign taxes
attributable to our Canadian operations. Our interim income tax provision is
based on an estimate of our full-year provision. Estimated provisions recorded
during interim periods may be periodically revised, if necessary, to reflect
current estimates.

At December 31, 1998, we had approximately $278,000,000 of U.S. Federal net
operating loss carryforwards (portions of which expire beginning in 2004),
$3,148,000 of U.S. Federal research and experimental income tax credit
carryforwards and $5,000,000 of foreign investment income tax credit
carryforwards (subject to expiration in 2008). Such net operating loss
carryforwards and tax credits are available to reduce future income tax
obligations, subject to certain annual limitations and other restrictions.

NET INCOME (LOSS). Our consolidated net income (loss) for the three-months ended
March 31, 1999 and 1998 was ($15,871,000) and $4,745,000, respectively. Our
space and ground infrastructure systems sector generated net income of
$14,586,000 and $15,184,000 for the first quarter of 1999 and 1998,
respectively. The satellite access products sector reported net losses of
$1,566,000 and $1,766,000 for the first quarters of 1999 and 1998, respectively.
Our satellite services sector reported net losses of $28,891,000 and $8,673,000
for the first quarters of 1999 and 1998, respectively.

Our satellite access products sector has introduced new products and formed new
business alliances in early 1999 and has implemented significant cost savings
measures. Consequently, we expect the trend of reduced losses to continue in
1999. In our satellite services sector, we expect the losses to continue to
increase in 1999 as compared to 1998, primarily as a result of increased losses
at ORBCOMM as explained above. The satellite services sector also includes the
results of our equity-method investment in CCI. As of March 31, 1999, CCI had
not yet raised additional third-party equity; consequently we recorded 100% of
CCI's losses under the modified equity method of accounting. CCI has several
near-term milestones that include, among others, raising capital and making
operational progress. If CCI's milestones are not met, or if an adequate market
for its products and services does not develop, we may be required to write-off
all, or a portion, of our $20,400,000 investment.

LIQUIDITY AND CAPITAL RESOURCES

Our growth has required substantial capital to fund investments in affiliates,
expanding working capital needs, certain business acquisitions, new business
initiatives, research and development and capital expenditures. We have funded
these requirements to date, and expect to fund our future requirements, through
cash generated by operations, working capital, loan facilities, asset-based
financings, joint venture arrangements and private and public equity and debt
offerings. We expect to continue to pursue potential acquisitions, new business
opportunities and equity investments that we believe would enhance our
businesses and to fund such transactions through existing cash, cash generated
by operations, loan facilities, joint ventures, the issuance of equity and/or
debt securities, and/or asset-based financings.

Cash and investments were $21,243,000, and total debt obligations were
approximately $251,189,000 at March 31, 1999. The outstanding debt is comprised
primarily of our $100,000,000 5% convertible subordinated notes, advances under
00our line of credit facilities, secured and unsecured notes, and asset-based
financings. At March 31, 1999, approximately $7,387,000 of cash and investments
was restricted because of outstanding letters of credit. Our current ratio was
1.2 at March 31, 1999 and December 31, 1998.

Our primary revolving credit facility provides for total borrowings from a
syndicate of banks of up to $200,000,000. Borrowings of $81,000,000 were
outstanding under the facility at March 31, 1999 at a weighted average interest
rate of 7% and were secured by accounts receivable. During the first quarter of
1999, the facility was amended to modify a financial covenant to provide full
availability under the facility. The facility prohibits the payment of cash
dividends, contains certain covenants with respect to our working capital
levels, fixed charges ratio, leverage ratio and net worth, and expires in
December 2002.

During the first quarter of 1999, we provided $18,450,000 in capital to
ORBCOMM. In addition, during the first quarter of 1999, we deferred invoicing
ORBCOMM for approximately $2,000,000 of work performed under our ORBCOMM
satellite and launch procurement agreement and will defer additional invoicing
during the remainder of 1999. Approximately one-half of the deferred invoice
amounts is expected to be advanced to Orbital by Teleglobe Inc. ORBCOMM will
require additional funding in 1999, and is analyzing different capital raising
alternatives. If ORBCOMM is unsuccessful in raising outside capital, we may
provide up to $35,000,000 of additional capital as required during the
remainder of 1999.

Our operations provided net cash of approximately $373,000 in the first quarter
of 1999. During the first quarter of 1999, in addition to our investment in
ORBCOMM, we invested approximately $12,963,000 in capital expenditures for
various satellite and launch vehicle production, manufacturing and test
equipment and office equipment, and $1,064,000 in business acquisitions. 



                                       16
<PAGE>   17




During the first quarter, we announced plans for a joint venture and an
acquisition. We continue to move toward completion of our $50,000,000 joint
venture with The Hertz Corporation ("Hertz") whereby Hertz will offer Magellan
automotive navigation systems in rental cars in the U.S., Canada and Europe. The
joint venture agreement, which is under negotiation, contemplates that we will
receive a 60% interest in exchange for a $30,000,000 investment to be made
primarily in the second half of 1999. In addition, we signed a merger agreement
with Lowrance under which we plan to acquire Lowrance and merge it into Magellan
in a stock-for-stock acquisition valued at approximately $27,500,000, subject to
receipt of all regulatory approvals and Lowrance shareholder approval. To
complete these transactions and to provide additional capital to ORBCOMM, we
need to amend several covenants in our primary credit facility and in our
$20,000,000 term loan. We are currently pursuing these amendments with our
lenders.

We are expanding our offices and satellite-related engineering, manufacturing
and operations facilities adjacent to our Dulles, Virginia headquarters.
Construction has commenced and is expected to continue into 2001. To finance the
majority of this expansion, we have negotiated a built-to-suit agreement with a
developer for the office expansion and expect to obtain third party debt
financing for the engineering, manufacturing and operating facilities.

Subsequent to March 31, 1999, we closed various business combinations (See
Recent Developments), with aggregate purchase prices of approximately
$78,000,000. Approximately $22,000,000 was financed through existing cash on
hand and credit facilities, while the balance was financed by issuing new debt
obligations.

We expect that our capital needs for the remainder of 1999 will, in part, be
provided by working capital, cash flows from operations, existing or new credit
facilities, and operating lease arrangements. We will also consider new equity
and debt financings.

YEAR 2000 ISSUES

We have developed a plan to prepare for potential "Year 2000" issues with
respect to various operational, technical and financial computer-related
systems. The plan has been designed to minimize risk to Orbital and its
customers using a standard industry five-phase approach. The five phases are
awareness, assessment, renovation, validation and implementation. We have
substantially completed the awareness and assessment phases, including a
comprehensive inventory of potentially affected systems. In many cases
renovation work is well under way and validation testing has begun with respect
to certain critical systems.

We plan to achieve our overall goal of Year 2000 readiness in mid-1999. The
first half of 1999 will be devoted to renovating, validating and implementing
its corrective action plan by reprogramming affected software when appropriate
and feasible, obtaining



                                       17
<PAGE>   18

vendor-provided software upgrades when available and completely replacing
affected systems when necessary.

The total costs to implement the plan, which costs include the already planned
replacement of existing systems to support our overall growth, are estimated to
be less than 1% of 1998 revenues. Approximately 85% of the estimated costs to
implement the plan have been incurred to date and the remaining costs are
expected to be incurred during the remainder of 1999. All costs, including the
costs of internal personnel, outside consultants, system replacements and other
equipment, will be expensed as incurred, except for long-lived assets, which
will be capitalized in accordance with our capitalization policies. We have not
postponed the implementation or upgrade of other systems as a result of focusing
on the Year 2000 plan.

As part of the plan, formal communication with our suppliers, customers and
other service providers has been initiated. To date, however, we have not
determined whether "Year 2000" issues affecting key suppliers, significant
customers (including the U.S. government), or critical service providers will
materially impact the company's cash flows or operating results. A "reasonably
likely worst case" scenario of the Year 2000 issue for us could include:
isolated performance problems with engineering, financial and administrative
systems; isolated interruption of deliveries from critical suppliers; product
liability or warranty issues; and the temporary inability of key customers to
pay amounts due us. Contingency plans are being prepared, and will be
implemented if necessary, including having sufficient liquidity available to
sustain a temporary interruption of cash receipts during early 2000 and the
identification of alternative suppliers for critical components. There can be no
assurance that we have identified, or will identify, all "Year 2000" affected
systems, suppliers, customers and service providers, or that our corrective
action plan will be timely and successful.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We do not have any material exposure to interest rate changes, commodity price
changes, foreign currency fluctuation, or similar market risks, although we do
enter into forward exchange contracts to hedge against specific foreign currency
fluctuations, principally with respect to the Canadian dollar. At March 31,
1999, the majority of our long term debt consisted of its $100,000,000, 5%
convertible subordinated notes, due 2002. The fair market value of these
convertible securities fluctuates with our stock price, and was $81,375,000 at
March 31, 1999.

PART II

OTHER INFORMATION

ITEM 1.     LEGAL PROCEEDINGS

            During the first quarter of 1999, a number of class
            action lawsuits were filed in the U.S. district court for 
            the Eastern District of Virginia against Orbital, an officer 
            and an officer/director, alleging violations of the federal 
            securities laws during the period from April 21, 1998 through 
            February 16, 1999 and seeking monetary damages. We believe that 
            the allegations are without merit and intend to defend vigorously 
            against such allegations.

(1)  - On September 16, 1997, the company sold $100 million of 5% convertible
       subordinated notes due October 2002. The notes are convertible at the
       option of the holders into Orbital common stock at a conversion price of
       $28.00 per share.

(2) -  Subsidiary stock options that enable holders to obtain subsidiary's
       common stock pursuant to effective stock option plans are included in
       computing the subsidiary's earnings per share, to the extent dilutive.
       Those earnings per share data are included in the Company's per share
       computations based on the Company's holdings of the subsidiary's stock.
       For the three months ended March 31, 1999, all such subsidiary stock
       options were anti-dilutive.
