ITEM 5.  OTHER EVENTS.

     On June 19, 2002, the Official Committee of Unsecured Creditors (the
"Creditors Committee") of Orbital Imaging Corporation ("ORBIMAGE") filed a
motion in the Bankruptcy Court in the Eastern District of Virginia seeking
authority to conduct discovery against us under Federal Rule of Bankruptcy
Procedure 2004. The following sets forth more details regarding our
relationship with ORBIMAGE and the genesis of this motion.

     ORBIMAGE

     In 1992, we formed ORBIMAGE to provide satellite-based remote sensing
services. Between 1992 and May 1997, we operated ORBIMAGE as a wholly owned
subsidiary, with a limited number of employees pursuing commercial and
government remote sensing market opportunities. During this time, we entered
into several agreements with ORBIMAGE, including a fixed price procurement
agreement to sell ORBIMAGE several satellite systems, and a services agreement
whereby we provided ORBIMAGE with certain administrative services and
technical support. Certain of our officers and directors served in similar
capacities with ORBIMAGE.

     Between May 1997 and February 1998, ORBIMAGE raised approximately $60
million in three private sales of its Series A convertible preferred stock to
accredited investors. As a result of these sales, and after giving effect to
the payment of dividends on the preferred stock in kind since its initial
issuance, at March 31, 2002, we owned 99.9% of ORBIMAGE's outstanding common
stock and approximately 52% of the total voting interests in ORBIMAGE after
giving effect to the conversion of ORBIMAGE's preferred stock.

     At the time of the initial sales of the preferred stock, we entered into
a stockholders agreement with the preferred stockholders, pursuant to which we
granted the preferred stockholders significant control rights. Among other
things, the stockholders' agreement provided for the reconstitution of the
ORBIMAGE board of directors. The number of board seats was fixed at five, with
two directors appointed by us, two appointed by the holders of the preferred
stock, and one independent director nominated by us, subject to the approval
of the two directors appointed by the holders of the preferred stock. The
stockholders' agreement required that at least one director appointed by the
preferred stockholders needed to approve material transactions with us or our
affiliates. In addition, the stockholders' agreement required that at least
one of the directors appointed by the preferred stockholders approve all
proposed transactions involving potential obligations in excess of $500,000.

     Between 1998 and 1999, ORBIMAGE raised $225 million in senior notes due
2005. The indenture governing these notes, which are non-recourse to us,
imposed



additional requirements with respect to the approval of certain affiliate
transactions, including the need to obtain a fairness opinion from a
disinterested third party for affiliate transactions with a value above $10
million. We believe that we complied with these provisions in our dealings
with ORBIMAGE.

     In 1999, ORBIMAGE and MacDonald, Dettwiler & Associates, Ltd. ("MDA"),
then our wholly owned subsidiary, entered into a license agreement granting
ORBIMAGE the worldwide distribution rights for data to be generated by the
Radarsat-2 satellite currently under construction by MDA. In June 2000, we
agreed to assist ORBIMAGE in negotiating a modification to this license
agreement. In connection with our agreement to assist in negotiating this
modification, we agreed to temporarily refund $20 million to ORBIMAGE if a
modification meeting certain requirements had not been agreed to by January
2001. At that same time, ORBIMAGE and we agreed to the termination of a stock
purchase agreement pursuant to which we had agreed to make certain equity
investments in ORBIMAGE based on its cash requirements.

     On February 9, 2001, the parties signed a new agreement that granted
ORBIMAGE a license to distribute Radarsat-2 data in the United States. Despite
the delay, we did not (and do not believe we were required to) temporarily
refund the $20 million to ORBIMAGE. Under the terms of the modified
distribution agreement, ORBIMAGE agreed to pay a total of $40 million to MDA
($30 million of which was credited from payment made under the original
contract) with the remaining $10 million dollars to be paid in two $5 million
installments, which are due from ORBIMAGE in July and December of 2002. We
also agreed that we would purchase receivables from ORBIMAGE in an amount
equal to the installment obligation, and to forward such payments to MDA, if
ORBIMAGE is unable to make these payments to MDA and if so requested by
ORBIMAGE. Any such purchase would be subject to bankruptcy court procedures
and approval and we may not be able to monetize any receivables to the full
extent of the price we pay.

     ORBIMAGE is currently in default on its interest payment obligations
under its senior notes. On April 5, 2002, ORBIMAGE filed a voluntary petition
of reorganization under Chapter 11 of the U.S. Federal Bankruptcy Code in the
Eastern District of Virginia. ORBIMAGE has not yet filed a plan of
reorganization. While we are attempting to negotiate a consensual plan of
reorganization with ORBIMAGE, certain of its major preferred stockholders and
the Creditors Committee, to date we have been unable to reach a mutually
satisfactory agreement.

     Under the procurement agreement, we are continuing to construct the
OrbView-3 satellite and related launch vehicle and ground segment. OrbView-3
is scheduled for launch in the second half of 2002. In September 2001, our
Taurus rocket that was carrying the OrbView-4 satellite for ORBIMAGE did not
achieve the mission's intended orbit and the satellite was lost. We also have
continued to provide




ORBIMAGE with certain administrative services and technical support, generally
on a cost-reimbursable basis. At December 31, 2001, ORBIMAGE owed us
approximately $7 million under our procurement agreement and our
administrative services agreement.

     We could become involved in litigation with ORBIMAGE, its other
stockholders and/or its creditors. ORBIMAGE has suggested that it might have a
claim against us with regard to the agreement described above to temporarily
refund to it $20 million. ORBIMAGE has also suggested that it may have other,
unspecified claims, including those relating to the Radarsat-2 transactions
discussed above and other claims arising out of alleged conflicts of interest
surrounding transactions among Orbital, ORBIMAGE and MDA.

     On June 19, 2002, the Creditors Committee filed a motion in the
Bankruptcy Court for authority to conduct discovery against us under Federal
Rule of Bankruptcy Procedure 2004. The stated purpose of the Creditors
Committee in seeking such discovery is to investigate the details of
ORBIMAGE's relationship and transactions with us in order to reveal whether
claims are warranted against us or certain of our directors, officers and
former officers on theories that might include, among others, wrongful control
and domination, breach of fiduciary duty, breach of contract, fraud and
misrepresentation.

     If any such litigation were to be commenced, the amounts sought by
ORBIMAGE and its stakeholders could be material. We believe we have valid
defenses to those claims that ORBIMAGE and the Creditors Committee have
articulated to date and we intend to vigorously defend any actions that may be
brought against us relating to ORBIMAGE.
