                                Current Report
                   For the Event Occurring on March 11, 1999



Item 1. Changes in Control of Registrant.
- ------  -------------------------------- 

        On March 11, 1999, Lowrance Electronics, Inc., a Delaware corporation,
        (the "Company") entered into an Agreement and Plan of Merger By and
        Among Lowrance Electronics, Inc., Orbital Sciences Corporation and
        Magellan Corporation (the "Merger Agreement") pursuant to which the
        Company will be acquired by Orbital Sciences Corporation, a Delaware
        corporation, ("Orbital").   The Merger Agreement provides for the merger
        of the Company with and into a majority owned subsidiary of Orbital,
        Magellan Corporation ("Magellan").   As a result of the proposed merger,
        when consummated, the separate corporate existence of the Company shall
        cease and Magellan shall continue as the surviving corporation.

        Pursuant to the Merger Agreement and subject to the terms and conditions
        set forth therein, at the time the merger is consummated, each share of
        common stock, par value $0.10 per share, of the Company (the "Company
        Common Stock") issued and outstanding immediately prior to the effective
        time of the merger will be canceled, and each holder of the Company's
        Common Stock immediately prior to the effective time of the merger shall
        have the right to convert the Company's Common Stock at the effective
        time of the merger at the Exchange Ratio (as defined below) into fully
        paid and nonassessable common stock, par value $0.01 per share, of
        Orbital ("Orbital Common Stock").

        The "Exchange Ratio" shall be equal to the quotient where (i) the
        numerator shall equal to the quotient obtained by dividing $27,500,000
        by the average closing price, rounded to four decimal points, of Orbital
        Common Stock as reported on The New York Stock Exchange, Inc. Composite
        Tape for the 20 consecutive trading day period ending (and including)
        the second trading day prior to the effective date of the merger (the
        "Average Price") and (ii) the denominator shall equal to the aggregate
        number of shares of Company Common Stock outstanding immediately prior
        to the effective time of the merger; provided, however, that the Average
        Price shall not be less than $22.00 and shall not be greater than
        $37.00.  The 

                                      -2-
<PAGE>
 
        Company shareholders will receive between 1,250,000 and 745,000 shares
        of Orbital Common Stock based on the Average Price. As of the close of
        business on March 17, 1999 Orbital Common Stock had a closing price of
        $24.375 per share. If the Orbital Common Stock had an Average Price of
        $24.375 that would result in the issuance of .2994 shares of Orbital
        Common Stock for each share of the Company or 1,128,205 shares of
        Orbital Common Stock for the 3,768,796 shares of the Company Common
        Stock issued and outstanding or a market value of approximately $7.30
        for each share of the Company. Notwithstanding the foregoing, if the
        Average Price of Orbital Common Stock is less than $21.00, the Company
        may unilaterally terminate the merger agreement without any cost
        whatsoever to the Company by providing to Orbital a written notice to so
        terminate the merger agreement; provided, however, that if Orbital
        notifies the Company in writing within three days from the date of
        receipt of the Company's written notice of such termination whereby
        Orbital agrees to adjust the Exchange Ratio such that the value of
        Orbital Common Stock, based on the Average Price, paid for each share of
        the Company Common Stock shall be equal to $6.97, the Company may not
        terminate the merger agreement because the Average Price is less than
        $21.00. In the event of any stock dividend, stock split,
        reclassification, recapitalization, combination or exchange of shares
        with respect to, or rights issued in respect of, Orbital Common Stock
        after March 11, 1999, the date of the execution of the merger agreement,
        and prior to the effective time of the merger, the Exchange Ratio will
        be adjusted according to the terms of the merger agreement.

        The boards of directors of the three companies have approved the
        transaction. The closing of the transaction is subject to a number of
        customary conditions, including approval of the shareholders of Company,
        and approval under the Hart-Scott-Rodino Antitrust Improvements Act of
        1976, as amended.  The transaction is intended to be tax-free to
        shareholders of Company.  Copies of the Merger Agreement and the press
        release are attached hereto as Exhibits A and B.  The foregoing
        description of the Merger Agreement is qualified in its entirety by
        reference to the full text of such Exhibit A.  The Merger Agreement and
        the press release are hereby incorporated by reference.

     Section 3.1.   Conversion of Securities.
                    ------------------------ 

          (a) At the Effective Time, each issued and outstanding share of

Company (the "Company Common Stock") issued and outstanding immediately prior to
              --------------------

whatsoever to the Company by providing to Parent a written notice to so
terminate this Agreement; provided, however, that if Parent notifies the Company
in writing within three days from the date of receipt of the Company's written
notice of such termination whereby Parent agrees to adjust the Exchange Ratio
such that the value of Parent Common Stock, based on the Average Price, paid for
each share of the Company Common Stock shall be equal to $6.97, the Company may
not terminate this Agreement because the Average Price is less than $21.00.  In
the event of any stock dividend, stock split, reclassification,
recapitalization, combination or exchange of shares with respect to, or rights
issued in respect of, Parent Common Stock after the date of this Agreement and
prior to the Effective Time, the Exchange Ratio and the number 21.00 contained
in this paragraph and in Section 9.1(j) shall

Company Common Stock in accordance with the foregoing may be hereinafter 
referred to as "Common Stock Merger Consideration"). From and after the
                ---------------------------------
Effective Time, all shares of the Company Common Stock, by virtue of the Merger
and without any action on the part of the holders thereof, will be canceled and
retired and cease to exist, and each holder of a certificate representing any
shares of the Company Common Stock immediately prior to the Effective Time (a 
"Common Stock Certificate") will thereafter cease to have any rights with

respect to such shares of the Company Common Stock, except the right to receive
the Common Stock Merger Consideration therefor upon the surrender of the Common
Stock Certificate in accordance with Section 3.2.
                                     ----------- 

          (c) No fractional share of Parent Common Stock shall be issued and in
lieu thereof, a cash payment shall be made pursuant to Section 3.2(e).  No
interest will be paid or will accrue on any cash in lieu of fractional shares of
Parent Common Stock or any unpaid dividends or distributions in respect of
Parent Common Stock payable upon surrender of Common Stock Certificates pursuant
to this Article III.

for cash all shares of the Series "A" Preferred Stock, par value $0.50 per
share, of the Company (the "Series "A" Preferred Stock") issued and outstanding
immediately prior to the Effective Time, upon delivery of the certificates(s)
representing shares of the Series A Preferred Stock and such other documents as
may reasonably be required by the Company and Parent.  The holders of Series "A"
Preferred Stock have agreed to surrender their Series "A" Preferred Stock to the
Company for cash in an amount per share of Series "A" Preferred Stock equal to
five times the result achieved by subtracting $6.375 from the product of the
Average Price, multiplied by the Exchange Ratio.

          (e) Each share of the Company Common Stock held in the treasury of the
Company and each share of the Company Common Stock owned by Parent, Magellan or
any direct or indirect Subsidiary of Parent or of the Company immediately prior
to the Effective Time shall be canceled and extinguished at the Effective Time
and no payment shall be made with respect thereto.

          (f) For purposes of this Agreement, "Merger Consideration" shall mean

Company Common Stock for which such consideration is to be paid.

Exchange Agent shall mail to each holder of record of Common Stock
Certificates(s) which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock, other than shares to be canceled or
retired in accordance with Section 3.1(e), (i) a letter of transmittal (which

transfer of ownership of Company Common Stock which is not registered in the
transfer records of the Company, a certificate representing the proper number of
shares of Parent Common Stock may be issued to a Person other than the Person in
whose name the Common Stock Certificate so surrendered is registered, if such
Common Stock Certificate shall be properly endorsed or otherwise be in proper
form for transfer and the Person requesting such payment shall pay any transfer
or other taxes required by reason of the issuance of shares of Parent Common
Stock to a Person other than the registered holder of such Common Stock
Certificate or establish to the satisfaction of Parent that such tax has been

pertaining to the shares of Company Common Stock theretofore represented by such
Common Stock Certificates.  At and after the Effective Time, the stock transfer
books of the Company will be closed, and there will be no further registration
of transfers of shares of the Company Common Stock or the Series "A" Preferred
Stock outstanding prior to the Effective Time.  If, at or after the Effective

          (d) No dividends or other distributions with respect to Parent Common
Stock with a record date after the Effective Time shall be paid to the holder of
any unsurrendered Common Stock Certificate with respect to the shares of Parent
Common Stock represented thereby, and no cash payment in lieu of fractional
shares shall be paid to any such holder pursuant to Section 3.2(e) until the

Subject to the effect of applicable laws, following surrender of any such Common
Stock Certificate, there shall be paid to the holder of the certificate
representing whole shares of Parent Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of any cash
payable in lieu of a fractional share of Parent Common Stock to which such
holder is entitled pursuant to Section 3.2(e) and the amount of dividends or
                               --------------                               
other distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Parent Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective time but prior to such surrender and a payment
date subsequent to such surrender payable with respect to such whole shares of
Parent Common Stock.

          (e) No certificates or scrip representing fractional shares of Parent
Common Stock shall be issued upon the surrender for exchange of the Common Stock
Certificates.  Each holder of Company Common Stock issued and outstanding at the
Effective Time which would otherwise be entitled to receive a fractional share
of Parent Common Stock upon surrender of the Common Stock Certificates for
exchange pursuant to this Article III (after taking into account all shares of
                          -----------                                         
Company Common Stock then held by such holder) shall receive, in lieu thereof,
cash in an amount equal to the value of such fractional share, which shall be
equal to the fraction of a share of Parent Common Stock that would otherwise be
issued multiplied by the Average Price.

          (f) Any portion of the Exchange Fund which remains undistributed to
the holders of Common Stock Certificates for six months after the Effective Time
shall be delivered to Parent, upon demand, and any holders of Common Stock
Certificates who have not theretofore complied with this Article III shall
                                                         -----------

payment of their claim for Parent Common Stock,

or distributions with respect to Parent Common Stock.

          (g) None of Parent, Magellan, the Company or the Exchange Agent shall
be liable to any Person in respect of any shares of Parent Common Stock (or
dividends or distributions with respect thereto) or cash from the Exchange Fund
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

          (h) The Exchange Agent shall invest any cash included in the Exchange
Fund, as directed by Parent, on a daily basis.  Any interest and other income
resulting from such investments shall be paid to Parent.

          (i) Surviving Corporation shall be entitled to deduct and withhold
from the Common Stock Merger Consideration otherwise payable pursuant to this
Agreement to any holder of the Common Stock Certificates such amounts as it is
required by regulations to deduct and withhold with respect to the making of
such payment under the Code, or any provision of state, local or foreign law.
To the extent that amounts are so withheld by Surviving Corporation, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the shares of Company Common Stock in respect of
which such deduction and withholding was made.

          (j)  If any Common Stock Certificate is lost, stolen, or destroyed,
upon the making of an affidavit of that fact by the Person claiming such Common
Stock Certificate to be lost, stolen, or destroyed and, if required by Parent,
the posting by such Person of a bond in such reasonable amount as Parent may
direct as indemnity against any claim that may be made against it with respect
to such Common Stock Certificate, the Exchange Agent will issue in exchange for
such lost, stolen or destroyed Common Stock Certificate the Parent Common Stock,
and any cash in lieu of fractional shares and any unpaid dividends or
distributions with respect to the Parent Common Stock, to which they are
entitled pursuant hereto.

officers, employees, investment bankers, attorneys and other agents and
representatives to, immediately cease any existing discussions or negotiations
with any Person other than Parent and Magellan (a "Third Party") heretofore

<PAGE>
 
such Third Party and (ii) negotiate, explore or otherwise communicate with such
Third Party, in each case only if (A) the Board of Directors of the Company by
majority vote determines in good faith upon considering the advice of outside
counsel that failing to take such action would constitute a breach of the
fiduciary duties of the Board of Directors of the Company under applicable law
(the Company Acquisition Proposal meeting the requirements of this clause (A), a
"Superior Proposal"), (B) prior to furnishing or disclosing any non-public
 -----------------                           
information to, or entering into discussions or negotiations with, such Third
Party, the Company receives from such Third Party an executed confidentiality
agreement with terms no less favorable in the aggregate to the Company than
those contained in the Confidentiality Agreement between the Company and Parent

public information delivered to such Third Party concurrently with such
delivery; provided however, that the Company shall not, and shall cause its
Affiliates not to, enter into a definitive agreement with respect to a Superior
Proposal unless (w) the Company has given Parent and Magellan five business days
notice of its intention to enter into such definitive agreement, (x) if Parent
and Magellan make a counter-proposal within such five business day period, the
Board of Directors of the Company shall have determined, in light of any such
counter-proposal, that the Third Party's proposal is still a Superior Proposal,
(y) the Company concurrently terminates this Agreement in accordance with the
terms hereof and pays any termination fees required under Section 7.10 and
agrees to pay any other amounts required under such Section and (z) such
agreement permits the Company to terminate it if it receives a Superior
Proposal, such termination and related provisions to be on terms no less
favorable to the Company, including as to fees and reimbursement of expenses, as
those contained herein.

     (d) The Company shall promptly (but in any event within one day of the
Company becoming aware of same) advise Parent and Magellan of the receipt by the
Company, any of its Subsidiaries or any of its bankers, attorneys or other
agents or representatives of any inquiries or proposals relating to a Company
Acquisition Proposal and any actions taken pursuant to subsection (c) above.
The Company shall promptly (but in any event within one day of the Company
becoming aware of same) provide Parent and Magellan with a copy of any such
inquiry or proposal in writing and a written statement with respect to any such
inquiries or proposals not in writing, which statement shall include the
identity of the parties making such inquiries or proposal and the material terms
thereof.  The Company shall, from time to time, promptly (but in any event
within one day of the Company becoming aware of same) inform Parent and Magellan
of the status and content of and development with respect to any discussions
regarding any Company Acquisition Proposal with a third party, including (i) the
calling of meetings of the Board of Directors of the Company to take action with
respect to such Company Acquisition Proposal, (ii) the execution of any letters
of intent, memoranda of understanding or similar non-binding agreements with
respect to such Company Acquisition Proposal, (iii) the waiver of any standstill
agreement to which the Company is or becomes a party, (iv) the determination by
the Board of Directors of the 

                                      29

Company to recommend to the stockholders of the Company that they approve or
accept a Superior Proposal or withdraw or modify in a manner adverse to Parent
or Magellan its approval or recommendation of this Agreement or the Merger, (v)
the determination by the Company to publicly disclose receipt of a Superior
Proposal and (vi) the waiver by the Company of any confidentiality agreement
with a Person proposing a Superior Proposal. For the avoidance of doubt, the
Company agrees that it will not enter into any definitive agreement with respect
to a Superior Proposal unless and until Parent and Magellan have been given
notice of the identity of the party making such Superior Proposal, the terms
thereof and developments referred to in the preceding sentence and the intent to
enter into such a definitive agreement at least five business days prior to the
entering into such agreement.

          (a  The Company shall, and from and after the Effective Time, Parent
and the Surviving Corporation shall, to the fullest extent permitted under
applicable law, defend, indemnify and hold harmless each person who is now, or

amounts paid in settlement in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, based in whole or in part on, or arising in whole or in part out
of, the fact that such person is or was an officer, director or employee,
whether pertaining to any matter existing or occurring at or prior to the
Effective Time and whether asserted or claimed prior to, or at or after, the
Effective Time (collectively, the "Indemnified Liabilities"); and (ii) all

Indemnified Liabilities based in whole or in part on, or arising in whole or in
part out of, or pertaining to, this Agreement, the Merger or the transactions
contemplated hereby.  The Company (or after the Effective Time, Parent and the
Surviving Corporation) shall be entitled to participate in and, to the extent
that it may wish, to assume the defense of any action, with counsel reasonably
satisfactory to the Indemnified Party but, if any Indemnified Party believes
that by reason of an actual or potential conflict of interest it is advisable
for such Indemnified Party to be represented by separate counsel, or if the
Company (or after the Effective Time, Parent and the Surviving Corporation)
shall fail to assume responsibility for such defense, such Indemnified Party may
retain counsel reasonably satisfactory to the Company (or after the Effective
Time, Parent and the Surviving Corporation) who will represent such Indemnified
Party, and the Company (or after the Effective Time, Parent and the Surviving
Corporation) shall pay all reasonable fees and disbursements of such counsel
promptly as statements therefor are received to the full extent permitted by
applicable law upon receipt of any undertaking contemplated by  the DGCL. The
Indemnified Party and the Company (or after the Effective Time, Parent and the
Surviving Corporation) will cooperate with each other and use all reasonable
efforts to assist each other in the vigorous defense of any such matter;
provided, however, that neither the Company, Parent nor the Surviving
Corporation shall be liable for any settlement of any claim effected without its
written consent.  Any Indemnified Party wishing to claim indemnification under
this Section 7.4, upon learning of any such claim, action, suit, proceeding or

Corporation, as applicable (but the failure to be so notified by an Indemnified
Party shall not relieve it from any liability which it may have under this
Section 7.4 except to the extent such failure prejudices such party).  The

indemnifying parties shall be required to pay for only one law firm, in addition
to local counsel, in each applicable jurisdiction selected by the Indemnified
Parties as a group in accordance with the foregoing provisions with respect to
each such matter unless there is, under applicable standards of professional
conduct, a conflict in any significant issue between the positions of any two or
more Indemnified Parties.

          (b) The Company does not currently maintain in effect policies of
directors' and officers' liability insurance.  Parent shall use its reasonable
efforts to obtain coverage for the Company's officers and directors with respect
to claims arising from facts or events which occurred after January 1, 1999
under policies of directors' and officers' liability insurance currently
maintained in effect by Parent, such coverage to be effective as of the the
Closing Date.

successors or assigns (i) consolidates with or merges into any other Person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers or conveys all or substantially all of
its properties and assets to any Person, then, and in each such case, to the
extent necessary, proper provision shall be made so that the successors and
assigns of Parent and the Surviving Corporation assume the obligations set forth
in this Section 7.4.

recommendation, or the failure to decline to solicit from the stockholders of
the Company such proxies, or the failure to decline to take any such other
action necessary to secure such a vote of the Company's stockholders, or the

Stock then owned by Parent, Magellan, or any other Affiliate of Parent, or with
respect to which Parent, Magellan, or any other Affiliate of Parent holds the

withdrawn, modified or changed its approval or recommendation of this Agreement
or the Merger in a manner adverse to Parent or Magellan.

                                                ---------------         
Agreement is terminated in accordance with Section 9.1(i), Parent shall

          (c) On or before, but effective as of the Effective Time, the Company

                           MAGELLAN CORPORATION AND
                           MARINE ELECTRONICS LEADER
                      LOWRANCE ELECTRONICS INC. TO MERGE

    -- $150 million consumer GPS-related business unit to be established --

SANTA CLARA, CA -- MARCH 11, 1999 -- Lowrance Electronics, Inc. (NASDAQ: LEIX)
of Tulsa, OK, will be merged into California-based Magellan Corporation, a
leading satellite access products company, as a result of a merger agreement
among those companies and Magellan's parent company Orbital Sciences Corporation
(NYSE: ORB).  The transaction will create a nearly $150 million, satellite-
based, consumer and recreational electronics business under the Magellan banner,
according to Magellan Chairman and Orbital President and CEO David W. Thompson.

  "This acquisition reflects our strategy of growing Magellan through market
expansion and acquisition of compatible technology companies. With approximately
$100 million in annual sales, Lowrance Electronics has long been a leading
player in the marine and recreational electronics business, with a special
expertise in both GPS satellite navigation and sonar technology.  As such,
Lowrance is a great fit with Magellan's already strong position in satellite-
based navigation and communications products for marine, aviation, outdoor
recreation and general consumer electronics markets, as well as a great addition
to Magellan's technology capabilities," Thompson noted.

  "Lowrance is a leading-edge technology company whose technical know-how in GPS
and sonar can be applied to emerging commercial and industrial applications and
integrated with other Magellan technologies such as GPS satellite navigation and
ORBCOMM satellite data communications," said Magellan President and CEO John
Huyett.

  Lowrance President and CEO Darrell Lowrance pointed to the "synergies between
the two organizations.  Both Lowrance Electronics and Magellan have pioneered
commercial applications of high technologies for consumer markets.  The combined
Magellan-Lowrance consumer products group represents a critical mass that is
well-positioned for growth and market expansion."

                                                                               1

  The acquisition will be accomplished through the exchange of stock between the
publicly traded Lowrance Electronics and Orbital.  Lowrance shareholders will
receive between 1,250,000 shares and approximately 745,000 shares of Orbital
common stock with the actual number of Orbital shares issued to be determined
based on the market price of Orbital stock prior to closing.  Based on Orbital's
Thursday, March 11, 1999, closing price, Lowrance shareholders would receive
approximately $24.1 million in value, or approximately $6.41 per share of
Lowrance common stock.  Closing is expected later this year.  The transaction
will be accounted for using the purchase method of accounting.

  Pending regulatory approval, the transaction will result in a stronger, more
capable satellite access products company employing more than 1,000 people in
locations throughout the world, including product development, manufacturing and
distribution centers in Santa Clara and San Dimas, CA; Rochester Hills, MI;
Tulsa, OK; Ensenada, Mexico; Moscow, Russia; Sydney, Australia; and Toronto,
Canada.

  The announcement of the Lowrance acquisition follows other recent business
news from Magellan including the unveiling of a new $50 million joint venture
between Magellan and Hertz Corporation to deploy 50,000 Magellan-built vehicle
navigation units in Hertz' car rental fleet, and an agreement to partner with
Topcon Corporation to develop GPS-based precision products for survey, GIS
mapping and machine control.

BACKGROUND ON LOWRANCE AND MAGELLAN

  Lowrance Electronics designs and manufactures sonar, GPS and aviation
instruments, distributing products under both the Lowrance and Eagle brands
throughout the United States and in 65 countries worldwide through a network of
retail outlets including boat dealers, marine electronics stores, mass
merchants, mail order catalogs, aviation electronics dealers and sporting goods
stores.  The company was founded by Carl and Darrell Lowrance in 1957 and
introduced the world's first commercial sonar instrument for sport fishing.
Since then the company has sold more than five million sonar units.  In 1991 the
company introduced its first GPS-based satellite navigation products for the
boating and fishing markets and later expanded its product offerings into the
hunting, hiking and general aviation markets.

Lowrance designs and engineers products at its Tulsa, OK headquarters and
manufactures products in Tulsa and in a new state-of-the-art electronics
assembly facility in Ensenada, Mexico.
