                                   PROPOSAL 1
                             ELECTION OF DIRECTORS

     Four directors are to be elected at the 2000 Annual Meeting for three-year
terms that expire in 2003. Nine other directors have been elected to terms that
end in either 2001 or 2002, as indicated below. Mr. James R. Thompson, who had
previously been elected as a director for the term ending in 2001, has been
nominated to fill the vacancy in the slate of directors for election in 2000
resulting from the retirement of Dr. John L. McLucas, who will assume an
advisory role as director emeritus. The term of office of each nominated
director will be for three years expiring at the 2003 Annual Meeting of
Stockholders and until a successor is elected and qualified or until such
director's death, removal or resignation. If any nominees for directors should
become unavailable, the Human Resources and Nominating Committee of the Board of
Directors would designate substitute nominees and proxies would be voted for
such substitutes. Management does not anticipate that any of the nominees will
become unavailable.

     In order to be elected, a nominee must receive the vote of a plurality of
the outstanding shares of Common Stock represented at the meeting and entitled
to vote. The four nominees for election as directors at the Annual Meeting who
receive the greatest number of votes properly cast for the election of directors
will be elected directors. Shares that are withheld and broker nonvotes will
have no effect on the outcome of the election.

     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF EACH OF
THE NOMINEES NAMED. Unless instructions are given to the contrary, it is the
intention of the persons named as proxies to vote the shares to which the proxy
is related FOR the election of each of the nominees listed below.

     Set forth below is certain information (as of March 1, 2000) concerning
each of the nominees and each person whose term of office as a director will
continue after the Annual Meeting.

INFORMATION CONCERNING THE BOARD AND ITS COMMITTEES

Meetings and Committees

     During 1999, the Board of Directors held 10 meetings. The Board has three
standing committees: the Audit and Finance Committee; the Human Resources and
Nominating Committee; and the Strategy and Technology Committee. The
biographical information in the immediately preceding section identifies the
committee memberships held by each director.

     The Audit and Finance Committee, which held 13 meetings in 1999, reviews
the Company's financial reports and other information relating to corporate
financial performance and planning, including major issues regarding accounting
and auditing practices; oversees the Company's internal controls that could
significantly affect the Company's financial statements; evaluates Company
financings and financial aspects of potential acquisitions, divestitures and
joint ventures; recommends annually the appointment of the Company's independent
auditors and reviews such auditors' compensation and performance; consults with
the independent auditors with regard to the plan of audit; and consults with the
independent auditors with regard to the Company's financial results, significant
accounting policies and issues, and the adequacy of internal controls of the
Company.

     The Human Resources and Nominating Committee, which held six meetings in
1999, administers the Company's stock option and stock purchase plans; approves
compensation arrangements for directors, executive officers and certain other
members of management; evaluates compensation plans and policies and makes
recommendations to the Board with respect thereto; oversees the Company's
defined contribution and deferred compensation plans; considers issues of
management development, evaluation and succession; reviews corporate human
resources matters, including issues relating to work force recruiting and
retention; and nominates candidates for positions on the Board. In addition, the
Committee will consider nominees recommended by stockholders for election as
directors if such recommendations are in writing, are filed with the Secretary
of the Company by the time specified in the Company's By-Laws and include the
information specified in the Company's By-Laws.

     The Strategy and Technology Committee, which held four meetings in 1999,
gives initial Board-level consideration to certain advanced technology and
business strategy issues, including competitive assessments; reviews and
assesses major programs and research and development activities; evaluates
potential acquisitions, divestitures and joint ventures; and evaluates technical
and market risks associated with new product development.

Director Compensation

     During 1999, four members of the Board of Directors were salaried employees
of the Company or its affiliates. Such employee-directors receive no additional
compensation for serving on the Board. Board members who are not salaried
employees receive separate compensation for Board service. That compensation
includes: (i) an annual retainer in the form of cash or restricted stock or a
combination of the two, (ii) attendance fees, (iii) stock options and (iv) in
some instances, restricted stock awards. All directors also are reimbursed for
out-of-pocket expenses in connection with Board and committee service.

     Retainer and Fees.  Nonemployee directors receive an annual retainer of
$7,500, along with $1,000 for each Board or committee meeting attended. As
described below, nonemployee directors may elect to receive their annual
retainer in restricted Common Stock of the Company.

     Options and Restricted Stock.  Under the 1997 Stock Option and Incentive
Plan (the "1997 Option Plan"), nonemployee directors receive an annual grant on
the first business day in January of options to purchase 3,000 shares of Common
Stock at an exercise price equal to the fair market value on that date. On

                                        5
<PAGE>   9

January 2, 1999, the option exercise price was $43.31 per share. The option
grant vests in its entirety one year from the grant date.

     The Board has adopted two nonemployee director compensation programs that
are intended to incentivize nonemployee directors to increase their equity
ownership in the Company and to directly align their financial interests with
those of stockholders. The first is a compensation program that allows
nonemployee directors to elect to receive shares of restricted Common Stock in
lieu of all or a portion of their annual cash retainer under the 1997 Option
Plan. Nonemployee directors making this election receive an additional matching
award of an equal number of shares of restricted Common Stock. The grant,
including the matching award of restricted Common Stock, vests in its entirety
two years from the date of grant. During 1999, the Company issued a total of
3,440 shares of restricted Common Stock to all ten eligible directors in lieu of
a cash annual retainer.

     The second compensation program allows the Company to match a nonemployee
director's purchase of up to $10,000 worth of Common Stock in the open market in
a calendar year with a grant of restricted Common Stock under the 1997 Option
Plan. The number of shares of restricted Common Stock granted is equal to the
dollar value of the nonemployee director's stock purchase in any given calendar
quarter divided by the average closing sales price of the Company's Common Stock
during that calendar quarter. The grant vests in its entirety in two years from
the date of grant. In 1999, the Company issued a total of 1,594 shares of
restricted Common Stock to five nonemployee directors who participated in the
program.

COMPENSATION COMMITTEE REPORT

     Overview and Philosophy.  The Human Resources and Nominating Committee (the
"Committee") is composed entirely of independent nonemployee directors and is
responsible for evaluating and determining the compensation of the Company's
senior executives. The Committee strives to ensure that compensation serves to
motivate and retain senior executives while also being in the best interests of
the Company and its stockholders. The Committee's philosophy relating to
executive compensation is to attract and retain highly qualified people at
industry competitive salaries, and to link the financial interests of Orbital's
senior management to those of the Company's stockholders. The Committee
endeavors to attain these goals by tying compensation to the achievement of
certain operational and financial objectives adopted semi-annually by the
Committee. To implement these objectives, the Company's compensation structure
has five general components: (i) base salary, (ii) annual cash bonuses and,
under certain circumstances, special cash bonuses, (iii) stock options, (iv)
stock ownership incentives and (v) under certain circumstances, stock
appreciation rights.

     Base Salary.  In the early part of each fiscal year, the Committee reviews
with Mr. David W. Thompson, Orbital's Chief Executive Officer, and approves,
with any modifications it deems appropriate, salary levels for the Company's
executive officers, including the Named Officers, and certain other members of
senior management. Generally, the salaries are determined subjectively,
intending to reflect the value of the job in the marketplace and the past and
expected future performance and contributions of the individual senior
executive, as well as the Company's overall growth and profitability.

     Annual Cash Incentive Bonus.  Under the Company's incentive bonus plan for
1999, the Chief Executive Officer was eligible to receive a bonus of up to 80%
of base salary, and the Company's President and Chief Operating Officer and
Executive Vice President and Chief Financial Officer were each eligible to
receive a bonus of up to 60% of base salary, based on individual achievements
and overall Company financial and operational performance. The Company's other
executive officers, including the other Named Officers, were eligible to receive
annual bonuses of up to 50% of base salary, based primarily on individual
achievements and their operating groups' financial and operational performance.
In January 1999 and July 1999, the Committee reviewed and adopted operational
and financial goals recommended by management for purposes of 1999 bonus
opportunities. Financial goals included achievement of target levels with
respect to revenues, backlog, earnings and cash flow, and the price of the
Company's Common Stock, with greater emphasis placed on earnings and the
performance of the Company's Common Stock. Operational goals included space
mission reliability and timeliness, new orders and contracts, new product
initiatives, adherence to schedules and budgets, and the completion of certain
corporate transactions.

     In July 1999 and January 2000, the Chief Executive Officer evaluated the
Company's and the individual groups' performance against the established goals,
and presented his evaluation, together with his reasoning and recommended bonus
percentages. The Committee then determined, based on the recommendations of the

                                        9
<PAGE>   13

Chief Executive Officer and other members of management and any other factors
the Committee considered relevant, the percentage of base salary to be awarded
as a bonus to each executive officer. In addition, the Committee established a
bonus pool for all other eligible employees. The Committee concluded that the
Company achieved moderate success in meeting its operational goals in the first
half of 1999 and was somewhat less successful in meeting its operational goals
in the second half of 1999. The Company failed to meet certain financial goals,
especially with respect to earnings and stock price. The total bonus percentage
awarded to each of the Named Officers, other than the Chief Executive Officer
(discussed below), was 50% of the target bonus amount, or 30% of annual base
salary for the President and Chief Operating Officer and the Executive Vice
President and Chief Financial Officer and 25% of annual base salary for the
other Named Officers.

     In addition to its annual incentive bonus plan, the Company also has a
policy of awarding special cash bonuses to an individual or a group in
recognition of exceptional achievement or effort. No special bonuses were
awarded to the Named Officers in 1999. Pursuant to an agreement with the Company
intended to incentivize satellite system marketing efforts, Mr. Lovell may be
eligible to receive a special annual cash bonus of up to $312,500 depending upon
new Space Systems Group business. As a result of such new business booked in the
past two years, Mr. Lovell received a special bonus of $232,000 for 1999 and
$312,500 for 1998.

     In 1999, the Committee awarded Performance Share Agreements to the
Company's Chief Executive Officer (discussed below) and to Mr. J.R. Thompson and
Mr. Pirone, the Company's President and Chief Operating Officer and Executive
Vice President and Chief Financial Officer, respectively. These agreements are
intended to provide these Named Officers with further incentive to enhance the
financial and operational strength of the Company by directly linking a
significant component of their compensation to the amount of appreciation in the
Company's Common Stock. Under these agreements, 50,000 performance shares each
were granted to Mr. J.R. Thompson and Mr. Pirone. The agreements provide for a
bonus to be paid in 2000 equal to the number of performance shares multiplied by
the amount by which the average closing sales price of the Company's Common
Stock for the month of March 2000 exceeded $30 per share. Messrs. Thompson and
Pirone were not entitled to receive any bonus in 2000 under their Performance
Share Agreements, in accordance with their terms. The agreements also provide
for a bonus to be paid next year determined by the number of performance shares
multiplied by the increase of the average closing sales price of the Company's
Common Stock for the month of March 2001 over the average closing sales price of
the Company's Common Stock for the month of March 2000. Bonuses earned pursuant
to these agreements are paid into the Named Officer's account under Orbital's
deferred compensation plan, with 50% of the amount vesting immediately and the
remainder vesting one year later.

     Stock Options.  The Committee believes that the award of stock options
provides meaningful long-term incentives that are directly related to the
enhancement of stockholder value. Under the 1997 Option Plan, stock options are
granted at an exercise price equal to or, in limited circumstances, greater than
the closing price of the Company's Common Stock on the date of the grant and
generally vest annually over a three-year period. Therefore, the value of the
grant to the recipient is directly related to an increase in the price of the
Common Stock. The Committee generally approves an annual grant to senior
executives, including the Named Officers. In addition, stock option grants
occasionally may be awarded throughout the year to individuals, including the
Named Officers. The number of stock options granted to each individual is
determined subjectively based on a number of factors, including the individual's
degree of responsibility, general level of performance, ability to affect future
Company performance, salary level, option holdings and recent noteworthy
achievements. Stock option awards are intended to incentivize employees to work
towards achieving operational and financial goals that management believes will
ultimately be reflected in stock value.

     In 1999, as a result of the steep decline in the Company's Common Stock and
the Committee's view that certain members of senior management should be further
incentivized to take the necessary steps to strengthen Orbital's stock price to
prior years' levels, the Committee decided to grant larger than usual awards to
the Company's Chief Executive Officer and Executive Vice President and Chief
Financial Officer with an exercise price set at $40 per share, which was
approximately twice the fair market value on the date of grant. Such options
vest annually over a four-year period.

                                       10
<PAGE>   14

     In addition to the options granted under the 1997 Option Plan, in 1999
certain senior managers, including certain of the Named Officers, were granted
ORBIMAGE common stock options under the ORBIMAGE 1996 Stock Option Plan. The
ORBIMAGE 1996 Stock Option Plan is administered by ORBIMAGE's Board of
Directors. These stock options were granted to incentivize continued efforts by
the grantees in assisting ORBIMAGE's development and operations.

     Stock Ownership Incentives.  Intending to incentivize senior management to
increase their equity ownership in the Company and thus to further motivate
performance, the Committee has instituted an executive officer loan program that
authorizes the Company to make a loan of up to $50,000 to each executive officer
solely for the purpose of purchasing Common Stock in the open market. Each loan
is for a term of four years with interest deferred. The Company has agreed to
forgive one-half of the principal amount and any accrued interest on the third
anniversary of the loan and the other one-half of the principal amount and any
accrued interest on the fourth anniversary of the loan if the executive officer
continues to hold all the shares of stock acquired with the loan proceeds on the
third anniversary of the loan and at least one-half of all such shares on the
fourth anniversary of the loan. Since 1997, five executive officers, including
three Named Officers, have participated in this program.

     In October 1998, the Committee adopted the 1999 Employee Stock Purchase
Plan ("ESPP"), which provides an opportunity for all employees, including senior
management, to purchase the Company's Common Stock at a 15% discount. The
Committee believes that promoting company-wide employee stock ownership will
benefit the Company by aligning employees' financial interests with those of
stockholders. The ESPP is intended to benefit the Company by increasing
employees' interest in the Company's growth and success and to assist in
recruiting and retaining high quality employees.

     Chief Executive Compensation.  Based on the Committee's review of the Chief
Executive Officer's performance, the overall performance of the Company and
compensation levels for comparable positions in the industry, the Committee
authorized a merit increase of $25,000 in Mr. Thompson's annual base salary from
$390,000 in 1998 to $415,000 effective January 1, 1999. The Committee maintained
the Chief Executive Officer's target bonus percentage at 80% of base salary for
1999. The total bonus percentage awarded the Chief Executive Officer under the
Company's incentive bonus plan in 1999 was 50% of target, or 40% of his base
salary. In determining the Chief Executive Officer's annual cash incentive
bonus, the Committee considered specific personal objectives of the Chief
Executive Officer for 1999, which included management goals with respect to the
operations of the Company's product line groups, certain financial and
operational goals for ORBCOMM and ORBIMAGE, and goals related to revenues,
earnings and stock price. As discussed above under Stock Options, the Committee
approved a grant of 250,000 options to Mr. Thompson in 1999 with an exercise
price of $40 per share, which was approximately twice the fair market value on
the date of grant. Such options vest annually over a four-year period.

     Since 1996, the Company has awarded the Chief Executive Officer with
Performance Share Agreements to provide him with further incentive to enhance
the financial and operational strength of the Company by directly linking a
significant component of his compensation to the amount of appreciation in the
Company's Common Stock. In 1999, Mr. Thompson declined to accept the performance
share award to which he would have otherwise been entitled based on the
Company's stock price performance in 1998 through the beginning of 1999. Under
the agreement awarded in 1999, 100,000 performance shares were granted to Mr.
Thompson. The agreement provides for a bonus to be paid in 2000 equal to the
number of performance shares multiplied by the amount by which the average
closing sales price of the Company's Common Stock for the month of March 2000
exceeded $30 per share. Mr. Thompson was not entitled to receive any bonus in
2000 under his Performance Share Agreement, in accordance with its terms. The
agreement also provides for a bonus to be paid next year determined by the
number of performance shares multiplied by the increase of the average closing
sales price of the Company's Common Stock for the month of March 2001 over the
average closing sales price of the Company's Common Stock for the month of March
2000. Bonuses earned pursuant to this agreement are paid into the Chief
Executive Officer's account under Orbital's deferred compensation plan, with 50%
of the amount vesting immediately and the remainder vesting one year later.

INDEMNIFICATION AGREEMENTS

     The Company has entered into substantially identical indemnification
agreements with each of its directors, the Named Officers and with certain other
officers and senior managers. The agreements provide that the Company shall, to
the full extent permitted by the Delaware General Corporation Law, as amended
from time to time, indemnify each indemnitee against all loss and expense
incurred by the indemnitee because he or she was, is or is threatened to be made
a party to any completed, pending or threatened action, suit or proceeding by
reason of the fact that he or she was a director, officer, employee or agent of
the Company or any of its affiliates, or because the Company has a right to
judgment in its favor because of his or her position with the Company or any of
its affiliates. The indemnitee will be indemnified so long as he or she acted in
good faith and in a manner reasonably believed by him or her to be in or not
opposed to the Company's best interest. The agreements further provide that the
indemnification thereunder is not exclusive of any other rights the indemnitee
may have under the Company's Restated Certificate of Incorporation, By-Laws or
any

                                       12
<PAGE>   16

agreement or vote of stockholders and that the Restated Certificate of
Incorporation or By-Laws may not be amended to affect adversely the rights of
the indemnitee.

     The Company also maintains insurance to indemnify its directors and
officers against certain liabilities, for which the Company paid approximately
$350,000 in premiums in 1999.

EXECUTIVE EMPLOYMENT AGREEMENTS

     The Company has entered into executive employment agreements with the
Company's executive officers, including each of the Named Officers, currently
employed by the Company. These agreements become effective in the event of a
"change of control" (as defined in the agreements) of the Company, and no
officer currently receives compensation under these agreements. Upon a "change
of control," each officer whose employment is terminated by the Company other
than for disability or "cause" (as defined in the agreements), or who terminates
his or her employment for "good reason" (as defined in the agreements), within
24 months following such "change of control," would receive his or her full base
salary through the termination date, plus a lump sum equal to two times the sum
of his or her annual base salary plus an amount equal to any bonus paid in the
previous year. In addition, all retirement benefits would vest, all insurance
benefits would continue for 24 months and all Company stock options would be
repurchased by the Company at the difference between the highest price paid in
the "change of control" transaction for shares of stock of the same class or
series and the exercise price of the stock option.

     Pursuant to an agreement with the Company, Mr. Lovell may be eligible to
receive a special cash bonus depending upon new business booked by the Space
Systems Group in each July 1 to June 30 twelve-month period. Under this
agreement, Mr. Lovell may be eligible to receive up to $312,500 per year. The
Company also pays Mr. Lovell a $2,000 per month housing allowance due to the
fact that his position at the Company requires him to live away from his
permanent residence.

RELATED TRANSACTIONS

     Halprin, Temple, Goodman & Maher, a law firm in which the spouse of one of
the Company's directors, Ms. Obuchowski, is a partner, has, since 1989, provided
the Company and its affiliates, ORBCOMM and ORBIMAGE, with legal services in
connection with licensing and regulatory matters involving the Federal
Communications Commission.

     In February 1998, the Company entered into a loan agreement with Mr. John
P. Huyett, who is currently the President of the Company's subsidiary, Magellan
Corporation, for the principal amount of $325,000, bearing an annual interest
rate of 5.5%, to assist in financing the purchase of a residence. The loan came
due in 1999. The Company agreed to extend the due date of the loan, with accrued
interest rolled into the principal amount, through December 31, 2000. The loan
will be secured by Mr. Huyett's principal residence. The total amount of the
loan outstanding as of April 7, 2000 was approximately $365,000.

     In September 1999, Mr. Ferguson, a director of the Company, exercised his
right under the Orbital Communications Corporation ("OCC") 1992 Stock Option
Plan (the "OCC Option Plan"), to cause OCC to repurchase 7,500 shares of the
32,500 shares of OCC common stock that Mr. Ferguson had acquired upon exercise
of options. OCC is a wholly owned subsidiary of Orbital. At that time, OCC
tendered to Mr. Ferguson $163,762.50 cash and a promissory note for $163,762.50
for the repurchase of Mr. Ferguson's OCC shares. The note bears an annual
interest rate of 5.35% and is due in September 2000.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities and Exchange Act requires Orbital's
executive officers and directors, and persons who beneficially own more than 10%
of the Company's Common Stock, to file reports of ownership and changes in
ownership on Forms 3, 4 and 5 with the SEC. Executive officers, directors and
greater than 10% stockholders are required by SEC regulation to furnish to the
Company copies of all Forms 3, 4 and 5 they file. Based solely on the Company's
review of the copies of such forms it has received and written representations
from certain reporting persons, the Company believes that, except as specified
below, all its executive officers and directors complied with the filing
requirements applicable to them with respect to transactions during fiscal year
1999. In 1998, Scott L. Webster gifted shares of Common Stock which was reported
late on a Form 5 filed in February 2000.

                              INDEPENDENT AUDITORS

     The Board of Directors has selected the firm of PricewaterhouseCoopers LLP
("PricewaterhouseCoopers") as the Company's independent auditors for the fiscal
year ending December 31, 2000. PricewaterhouseCoopers has served as the
Company's independent auditors since May 10, 1999. Representatives of
PricewaterhouseCoopers are expected to be present at the Annual Meeting and will
be available to respond to appropriate questions and make a statement if they so
desire.

     Previously, KPMG LLP ("KPMG") served as the Company's independent auditors
since 1989. On April 22, 1999, the Company, at the direction of the Audit and
Finance Committee of the Board of Directors, notified KPMG that the Company had
determined to change auditors. PricewaterhouseCoopers has been given full
authorization by the Company to speak with KPMG, and has done so. The Company
has not restricted KPMG from responding fully to such inquiries with respect to
any matters.

     KPMG issued an audit report, dated February 16, 1999, except as to Note 13,
which was as of March 18, 1999 (the "Audit Report"), on the consolidated
financial statements of the Company as of and for the fiscal years ended
December 31, 1998 and December 31, 1997. The Audit Report did not contain any
adverse opinion or disclaimer of opinion and was not qualified or modified as to
uncertainty, audit scope or accounting principles. As discussed below, however,
in a letter dated October 28, 1999, KPMG informed Orbital that such Audit
Report, together with its audit report for the fiscal year ended December 31,
1997, should no longer be relied upon.

     As was reported in Orbital's Report on Form 8-K dated April 22, 1999 (the
"Form 8-K"), in connection with the audit of the Company's 1998 consolidated
financial statements, KPMG proposed adjustments to the Company's previously
issued 1998 quarterly financial statements and to the results for the 1998
fourth quarter as initially prepared by the Company. The proposed adjustments
were based on KPMG's interpretation of specific accounting standards. While the
Company believed that its own interpretation and application of accounting
standards had been reasonable under the circumstances, after discussion with
KPMG and the Audit and Finance Committee, the Company determined to restate the
previously issued 1998 unaudited quarterly financial statements in the manner
recommended by KPMG. The Company also agreed to adjust its results for the
fourth quarter of 1998 in the manner recommended by KPMG. Except as described
herein, for
                                       15
<PAGE>   19

the year ended December 31, 1998, there were no disagreements with KPMG on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which disagreements, if not resolved to the
satisfaction of KPMG, would have caused KPMG to make reference to the subject
matter of the disagreements in connection with its report.

     On April 14, 1999, KPMG advised the Company by letter that KPMG believed
that there were material weaknesses in the Company's systems of internal
controls relating to the manner of recording adjustments to financial
information submitted by subsidiaries and operating divisions of the Company. In
particular, KPMG cited:

     - adjustments made in the first and second quarters of 1998 to capitalize
       certain product enhancement costs at the Company's subsidiary, Magellan
       Corporation, which appeared to KPMG to have been made outside Magellan's
       system of internal accounting controls and which were not recorded in its
       general ledger and were not included in closing consolidating entries for
       such quarters;

     - an adjustment made in the third quarter of 1998 to increase revenue
       recognized pursuant to a contract at the Company's subsidiary, MacDonald,
       Dettwiler and Associates Ltd, which was not reflected in its general
       ledger and which was not included in closing consolidating entries in the
       third quarter; and

     - corporate adjustments made in closing consolidating entries to certain
       long-term contract accounting at the Company's operating divisions, which
       had the effect of increasing revenues and profits on some of these
       contracts and which KPMG believed did not properly consider all the
       information used by the operating divisions.

     In its letter, KPMG further advised the Company that KPMG's Audit Report
was not affected by the material weakness conditions that it believed existed,
and that KPMG considered such material weaknesses in determining the nature,
timing and extent of its audit tests. Prior to the receipt of KPMG's letter, the
Company and the Audit and Finance Committee had discussions with KPMG indicating
disagreement with KPMG's conclusions and had expressed to KPMG the Company's
view that the adjustments in question were properly recorded by the Company
after appropriate consultation with the subsidiaries and operating divisions
involved.

     On May 13, 1999, the Company received a response from KPMG to the Company's
Form 8-K. In its response, KPMG disagreed with the Company's characterization of
the nature of adjustments that had been made to the 1998 unaudited quarterly
financial statements, stating that "KPMG believe(d) that the adjustments were
not based solely on 'KPMG's interpretation of the specific accounting
standards."' KPMG further indicated that, in its view, "the adjustments
included: (a) adjustments required to correct errors by the Company in recording
certain transactions, which errors caused the Company to record those
transactions in a manner that was inconsistent with generally accepted
accounting principles; and (b) adjustments required to correct the Company's
incorrect application or incorrect interpretation of specific generally accepted
accounting principles."

     KPMG also described the matters which led to these adjustments as follows:

     - "During each of the four quarters of 1998, the Company capitalized an
       aggregate of approximately $6.6 million of product enhancement costs at
       its Magellan subsidiary based on an incorrect application of generally
       accepted accounting principles.

     - During the third quarter of 1998, the Company recognized approximately
       $5.8 million in revenue on a contract at the Company's MacDonald
       Dettwiler & Associates subsidiary based on an incorrect application of
       generally accepted accounting principles.

     - During the fourth quarter of 1998, the Company recognized approximately
       $1.5 million of revenue with respect to a contract, the terms of which
       was not finalized with the customer until after the conclusion of the
       quarter.

                                       16
<PAGE>   20

     - During the fourth quarter of 1998, the Company recognized approximately
       $5.4 million of revenue with respect to certain of its long-term
       contracts through incorrect reductions to cost estimates to complete
       those contracts.

     - During the fourth quarter of 1998, the Company recognized approximately
       $3.8 million of revenue with respect to a certain contract based on an
       incorrect application of generally accepted accounting principles.

     - During the fourth quarter of 1998, the Company recognized approximately
       $5.1 million of revenue relating to sales to an equity method investee
       based on an incorrect application of generally accepted accounting
       principles."

     For each of the matters described above, KPMG proposed adjustments, all of
which were recorded by the Company, to reverse the amounts originally recorded
by the Company.

     In addition, KPMG asserted that (i) the items referred to in KPMG's
material weakness letter had caused KPMG to expand significantly the scope of
its audit procedures, (ii) it had advised Orbital that it would stand for
reappointment as the company's principal accountants only if Orbital hired an
experienced chief accounting officer who would have the ultimate authority to
make accounting decisions at the Company, (iii) it wished to discuss this
condition with Orbital's Audit and Finance Committee and (iv) its appointment
was terminated by Orbital prior to KPMG having such discussions with the full
Audit and Finance Committee.

     On the Company's Form 8-K dated May 14, 1999, the Company reported that it
disagreed with a number of the statements made by KPMG in its response letter.
Orbital reiterated its belief that (i) its interpretation and application of
accounting standards in the quarterly financial statements as originally filed
were reasonable, however, the Company accepted KPMG's interpretation of complex
accounting standards and agreed to the restatement proposed by KPMG and (ii)
KPMG's characterizations and enumerations of fourth quarter adjustments in the
course of the audit were unnecessary. The Company further stated, "Any audit
involves adjustments proposed by an auditor that are then discussed with its
client. Based on additional analyses of facts by the client and the auditor, the
auditor may then modify its proposed adjustments or not. That was the process
engaged in by Orbital and KPMG. What is significant is that (1) in Orbital's
audited financial statements, all adjustments finally proposed by KPMG were
recorded by the Company and (2) as indicted in KPMG's unqualified opinion, the
Company's financial statements for the year ended December 31, 1998 complied
with GAAP and contained all appropriate disclosures." The Company also reported
that it continued to disagree with KPMG's assertions with respect to alleged
material weaknesses.

     In October 1999, after questions were raised pertaining primarily to
Orbital's previous accounting for certain transactions related to its
investments in ORBIMAGE and CCI, the valuation of its subsidiary, Magellan, and
certain other matters, KPMG informed Orbital that KPMG's 1998 and 1997 audit
reports should no longer be relied upon. The Company announced that it would
restate its financial statements for the foregoing periods. In addition the
Company will restate its interim financial statements for 1999.
