     1. To elect nine directors;

     2. To consider  and act upon a proposal to amend the  Company's  1994 Stock

Andersen LLP as independent  accountants  for American Mobile for the year 1999;
and

Only  holders  of  record  of  American  Mobile's  common  stock at the close of

such  stockholders  will  be  available  at the  Company's  headquarters,  10802

The  accompanying  proxy is  solicited  on behalf of the Board of  Directors  of
American Mobile Satellite  Corporation  ("American Mobile" or the "Company") for
use at the annual  meeting of  stockholders  to be held on May 26, 1999, and any
adjournments  thereof.  The annual  meeting will be held at the Sheraton  Reston
Hotel, 11810 Sunrise Valley Drive, Reston,  Virginia,  and will commence at 9:00
a.m.  The  stockholder  giving the proxy may revoke it at any time  before it is
exercised at the meeting by  delivering  to the  Secretary of American  Mobile a
written  instrument of revocation or a duly executed proxy bearing a later date.
This proxy statement and the accompanying  form of proxy are being first sent to
stockholders on or about April 21, 1999.

The only class of  securities  of American  Mobile  entitled to vote at the 1999
annual meeting is its common stock, of which 32,303,098  shares were outstanding
on March 31, 1999. Only stockholders of record at the close of business on March
31,  1999 will be entitled to vote at the annual  meeting.  The  presence of the
holders of a  majority  of the issued  and  outstanding  shares of common  stock
entitled  to vote at the  annual  meeting,  either in person or  represented  by
properly  executed  proxies,  is  necessary  to  constitute  a  quorum  for  the
transaction  of  business at the  meeting.  If there are not  sufficient  shares
represented  in person or by proxy at the meeting to  constitute  a quorum,  the
meeting may be postponed or adjourned in order to permit further solicitation of
proxies by the Company.  Proxies  given  pursuant to this  solicitation  and not
revoked will be voted at any  postponement  or adjournment of the annual meeting
in the manner described elsewhere in this proxy statement.

Each  stockholder  has one vote for each share of common stock held,  and in the
election of directors is entitled to cumulate his or her votes. Under cumulative
voting,  each stockholder is allowed that number of votes equal to the number of
director  positions to be filled  (nine)  multiplied  by the number of shares of
common stock owned.  The  stockholder  may  distribute  those votes among one or
more, or all, of the nominees as the stockholder desires.  However, as described
below, the accompanying proxy reserves to the persons named therein the right to
distribute the votes  represented by such proxy in their  discretion in order to
maximize  the  likelihood  of  electing  the  full  slate  of  directors.  Under
cumulative  voting,  directors  are  elected by a  plurality  of votes  cast.  A
withheld vote on any nominee will not affect the voting results.

With respect to Proposal 2, approval of amendments to the 1994 Stock Option Plan
for Non- Employee Directors, and with respect to Proposal 3, ratification of the
appointment  of Arthur  Andersen  LLP as  independent  accountants  for American
Mobile for the year 1999, the  affirmative  vote of the holders of a majority of


                                        1

<PAGE>


the shares  present in person or  represented by proxy at the annual meeting and
entitled to vote will be required.  Abstentions will be treated as votes present
and  entitled  to vote and thus will have the  effect  of a vote  against  these
proposals.

Brokers who hold shares in street name for beneficial  owners have the authority
to vote on the matters  scheduled  for the meeting if the brokers do not receive
instructions from beneficial owners.  Broker non-votes (arising from the lack of
instructions from beneficial  owners) will not affect the outcome of the vote on
Proposal 2 or Proposal 3. Broker  non-votes will be counted in  determining  the
existence of a quorum.

The cost of soliciting  proxies in the form  enclosed  herewith will be borne by
the Company.  In addition to the  solicitation  of proxies by mail, the Company,
through its directors,  officers and regular employees, may also solicit proxies
personally or by  telephone.  The Company also will request  persons,  firms and
corporations  holding  common  stock  in their  names  or in the  names of their
nominees, which are beneficially owned by others, to send proxy materials to and
obtain  proxies from the beneficial  owners,  and the Company will reimburse the
holders for their reasonable out-of-pocket expenses in so doing.


                            1. ELECTION OF DIRECTORS
                            ------------------------

It is  intended  that the  persons  named in the proxy  will,  unless  otherwise
instructed,  vote for the election of the nine nominees listed below to serve as
directors  until  the next  annual  meeting  of  stockholders  and  until  their
respective  successors are elected and qualified.  If for any reason any nominee
should  not be  available  for  election  or able to  serve as a  director,  the
accompanying  proxy  may be  voted  for the  election  of a  substitute  nominee
designated  by the Board of Directors  and will be voted for the election of the
other nominees named therein. In any event, management reserves the right in its
discretion to distribute the total votes  represented by the proxies unevenly or
among less than all of the persons named (or their substitutes), as permitted by
cumulative  voting,  in order to maximize  the  likelihood  of electing the full
slate of directors.

have such amounts paid to them directly.  All other directors  elected to forego

Directors (an "Eligible  Director") is entitled to receive  options  exercisable
for the Company's  common stock as provided in the  Company's  1994 Stock Option
Plan for  Non-Employee  Directors  ("Director  Plan").  Pursuant to the Director
Plan, each Eligible Director (other than directors  electing not to receive such
options)  receives an initial  option to purchase  1,000 shares of common stock,
and  automatically  receives annually an option to purchase 500 shares of common
stock at an exercise price equal to the fair market value of the common stock on
the date of grant.  Each option expires on the earlier of (i) ten years from the
date of grant or (ii) seven months after a director's  termination of service as

Agreements Among Stockholders
- -----------------------------

Stockholders' Agreement
- -----------------------

American  Mobile and each  holder of shares of common  stock who  acquired  such
shares prior to the Company's  initial  public  offering of 8,500,000  shares of
common  stock,  which  was  completed  December  20,  1993,  are  parties  to  a
Stockholders'  Agreement,  amended  and  restated  as of  December  1, 1993 (the
"Stockholders' Agreement"). The remaining parties to the Stockholders' Agreement
(principally  Hughes,  Singapore Telecom,  and AT&T Wireless) hold approximately
50% of the  outstanding  shares of common stock on a fully  diluted  basis.  The
Stockholders'  Agreement sets forth agreements among the parties relating to the
governance   of  the   Company,   ownership   of  shares   and  the  voting  and
transferability of common stock and other matters.  The Stockholders'  Agreement
limits the  Company's  activities  to engaging in the  communications  business,
providing,  marketing and operating a mobile  satellite  service and engaging in
activities  necessary,  appropriate or reasonably related to the foregoing.  The
Stockholders'  Agreement  provides  that the  parties  will  not vote to  remove
members of the Board of Directors  except for cause and that they will not elect
or permit the election of a director who is not a United States citizen, if such
action would cause the Company to violate  applicable  law,  regulations  or FCC
policy.

In the Stockholders'  Agreement,  certain  stockholders who, together with their
affiliates,  own in excess  of five  percent  of the  common  stock  ("Specified
Stockholders")  have also  agreed to cause  their  representatives  on  American
Mobile's Board of Directors to appoint to the Executive  Committee two directors
(and one alternate)  nominated by each of the two Specified  Stockholders  which
are parties to the  Stockholders'  Agreement  that hold the  greatest  number of
shares of common stock and one  director  (and one  alternate)  nominated by the
Specified  Stockholder  that holds the third greatest number of shares of common
stock,  provided that each Specified Stockholder making such nomination holds at
least  15%  (the  "Threshold  Percentage"),  of the  outstanding  common  stock.
Notwithstanding  the  foregoing,  regardless  of  whether  any  other  Specified
Stockholder which is a party to the Stockholders'  Agreement holds the Threshold
Percentage of the outstanding shares of common stock, during the period that any
single  Specified  Stockholder  or group of  affiliated  stockholders  which are
parties to the  Stockholders'  Agreement are the record holders of more than 50%
of the outstanding common stock, the Specified Stockholders have agreed to cause
their  Board  representatives  to vote  for  the  appointment  to the  Executive
Committee of nominees of that Specified Stockholder. The Stockholders' Agreement
also  provides that no person shall be elected to the Board of Directors if such
election  would  violate  the  Communications  Act  of  1934,  as  amended  (the
"Communications Act") or regulations thereunder.  Furthermore, the Stockholders'
Agreement provides that no director shall be elected to the Executive  Committee
if such election,  in the opinion of counsel for American Mobile,  would raise a
reasonable   prospect  of  violating  the   Communications  Act  or  regulations
thereunder.  Moreover,  before any Specified Stockholder may elect a director of
American  Mobile  who is not a  United  States  citizen,  it  must  first  allow
Singapore  Telecom to elect such a director,  provided  Singapore  Telecom casts
sufficient cumulative votes to elect a director.

The  Communications  Act provides that certain FCC licenses may not be held by a
corporation  of which more than 20% of its capital  stock is  directly  owned of


                                        8

<PAGE>


record or voted by non-U.S. citizens  or entities or their  representatives (the
Company's   wholly-owned   subsidiary,   AMSC  Subsidiary   Corporation   ("AMSC
Subsidiary"),  as the holder of the FCC  license to  construct  and  operate the
Company's mobile satellite  services system, is subject to these  restrictions).
Further,  the  Communications  Act provides that certain FCC licenses may not be
held by a corporation  controlled by another corporation if more than 25% of the
controlling  corporation's capital stock is owned of record or voted by non-U.S.
citizens or entities or their  representatives  ("Alien Ownership"),  if the FCC
finds that the public  interest is served by the refusal or  revocation  of such
license  (American  Mobile  controls AMSC Subsidiary and therefore is subject to
these  restrictions).   The  Stockholders'  Agreement  contains  procedures  for
reducing  the risk that the  Company  will fail to comply  with the FCC's  Alien
Ownership restrictions as a result of the ownership of the stockholders party to
that Agreement or their respective holdings in American Mobile.

The Stockholders' Agreement provides that when a Specified Stockholder transfers
common stock not acquired by such Specified  Stockholder in the open market, the
transferee shall become a party to the Stockholders' Agreement, and shall assume
all of the transferring Specified Stockholder's rights and obligations under the
Stockholders'  Agreement,  provided such transferee together with its affiliates
would,  giving effect to such  transfer,  hold in excess of 5% of the issued and
outstanding common stock.

The Stockholders'  Agreement  continues until terminated by the affirmative vote
of the holders of three-fourths of the issued and outstanding  common stock held
by parties to the Stockholders' Agreement. It may be amended by a three-fourths'
vote of the Specified  Stockholders,  except that  amendments to the  provisions
providing  for  registration  rights  and  certain  other  matters  require  the
affirmative vote of the holders of three-fourths of the outstanding common stock
held by parties to the Stockholders' Agreement.

Motorola Agreements
- -------------------

In  connection  with the  acquisition  of ARDIS from  Motorola by the Company on
March 31, 1998 (the "Acquisition"), and pursuant to the Stock Purchase Agreement
dated as of  December  31,  1997,  as  amended  March 31,  1998  (the  "Purchase
Agreement"),   American  Mobile,  Motorola  and  certain  of  American  Mobile's
principal  stockholders  (Hughes,  Singapore  Telecom  and AT&T  Wireless)  (the
"Participating   Stockholders")   have  agreed  to  certain   participation  and
registration rights with respect to American Mobile's common stock.

Pursuant to the terms of the  Participation  Rights  Agreement  entered  into on
December 31, 1997 (the "Participation Rights Agreement"),  in the event that one
of the  Participating  Stockholders  seeks to  transfer  its shares of  American
Mobile's  common  stock  other than in a Rule 144 or public  stock  exchange  or
Nasdaq Stock  Market  transaction  (a  "Transfer")  at a time at which  Motorola
beneficially owns 5% or more of American  Mobile's common stock,  Motorola would
have a right to receive  notice of the intended  Transfer by such  Participating
Stockholder   and  a  right  to   participate   (proportionate   to   Motorola's
stockholdings  relative  to those  of such  Participating  Stockholder)  in such
contemplated   Transfer.   Under  the  Participation   Rights   Agreement,   the
Participating Stockholders would be entitled to similar notice and participation
rights in the event of an intended  transfer by  Motorola  of its  interests  in
American Mobile's common stock.

                                        9

<PAGE>



The  Participation  Rights  Agreement also provides that in connection  with the
Acquisition,  Motorola  would be  entitled to certain  demand and  participation
("piggyback")  registration rights with respect to the shares of common stock to
be issued to Motorola  (directly or following  exercise of its warrants) as part
of the purchase price of ARDIS.  Pursuant to the Participation Rights Agreement,
after the first year  following  the  Acquisition,  Motorola or its  transferees
would be  entitled  to two demand  registrations  with  respect to its shares of
American Mobile's common stock, subject to certain  registration  priorities and
postponement rights of American Mobile. In addition,  Motorola would be entitled
to piggyback  registration in connection with any  registration of securities by
American Mobile (whether or not for its own account) on a form which may be used
for registration of the common stock held by Motorola.  Under the  Participation
Rights Agreement,  Motorola's  piggyback  registration rights would have certain
priorities  for sale over those of other parties  (including  the  Participating
Stockholders).  Motorola's  priority  rights,  however,  would  not  extend to a
primary  registration on behalf of American Mobile or to the registration rights
relating to the 12 1/4% senior notes and related  warrants (the "high yield debt
offering") issued by the Company in connection with the Acquisition.

Compensation and Stock Option Committee Report
- ----------------------------------------------

Introduction
- ------------

The Company's  compensation  policy for 1998 was established by the Compensation
and Stock Option  Committee  consisting of Messrs.  Quartner,  Shaw and Smith In
accordance  with this policy,  which is discussed in greater  detail below,  the
Compensation  and Stock Option  Committee  set the base salaries of, and awarded
cash bonuses,  and stock options to, American  Mobile's  Executive  Officers for
1998.  None of the members of the  Compensation  and Stock Option  Committee are
employees of the Company.

American Mobile's Compensation Policy.  American Mobile's compensation policy is
- -------------------------------------
designed  to (i) attract and retain a talented  and highly  motivated  executive
corps,  (ii) reward those  executives for attaining  personal,  departmental and
company-wide  goals and (iii) align the interests of those  executives  with the
interests of the Company's  stockholders.  Each of these objectives is addressed
to a greater or lesser extent by each of the three components of the executive's
compensation  - base salary,  annual  bonus and equity based awards  (restricted
stock awards and stock options).

In  determining   the  base  salaries  of  Executive   Officers  for  1998,  the
Compensation and Stock Option Committee considered its actions in 1997 to forego
merit  increases or reduce  salaries for  Executive  Officers.  The  Committee's
actions for 1997 had been made in view of the economic  constraints  then facing
the   Company,   the   desirability   of   placing   a   greater   emphasis   on
performance-based,  at-risk  compensation and the positive message to be derived
throughout the  organization  by  implementation  of such a salary  reduction or
freeze at the most senior management levels.

The Committee also considered the considerable  efforts of senior  management in
effecting the successful  acquisition of ARDIS and related financing in March of
1998. In light of these  considerations and the overall compensation policy, the
Committee  determined that merit  increases  should be paid in 1998 and returned
the reduced salary of Mr. Parsons to its original level.


                                       11

<PAGE>




In 1998, the Committee also began its evaluation of the  consistency of base and
bonus  compensation for executive and senior management in the combined American
Mobile-ARDIS organization.  Compensation for Mr. Purnell, who joined the Company
in March 1998 as its  President,  was  determined  consistent  with the existing
compensation   structure  for  other  Executive  Officers  of  American  Mobile.
Compensation  for other senior officers of the combined  company were considered
and modified towards a goal of comparable treatment.

Annual   Bonus.   American   Mobile's   Executive   Officers  are  eligible  for
- --------------
discretionary annual bonuses.  Performance  objectives are set annually for each
executive,  with relative values set for attaining each objective.  At year end,
the Chief Executive Officer of the Company assesses each executive's  success in
obtaining  his  or  her  performance   objectives,   and  makes  an  appropriate
recommendation  to the Compensation  and Stock Option  Committee  regarding such
executive's annual bonus. Such  recommendations are generally based, in part, on
quantitative  factors  relating to  attainment of corporate  objectives  and, in
part, on more qualitative factors relating to individual performance.

In 1998, the Committee determined that 92.5% of established corporate objectives
had been met and approved payment of discretionary bonuses as recommended.

Equity Based Awards.  The number and type of equity based awards granted to each
executive is determined by the  Compensation  and Stock Option  Committee in its
discretion.  In making its  determination,  the  Compensation  and Stock  Option
Committee  considers  the  executive's  position  at  the  Company,  his  or her
individual  performance,  the  number of  options  or other  awards  held by the
executive  (if any) and other  factors,  including an analysis of the  estimated
amount potentially realizable from the award.

In January  1999,  the  Committee  approved the grant of stock options to senior
management to continue to align the  interests of  management  with those of the
stockholders,  and to incentivize and retain those executives.  In addition, the
Board of Directors  exercised its discretion to waive certain  conditions to the
first year's vesting of previously  awarded restricted shares to each of Messrs.
Goldsmith  and Ms.  Segal to  recognize  their  efforts  in 1998 and to  provide
continued   incentives  for  and  retention  of  those   executives.   Upon  the
recommendation  of Messrs.  Parsons and Purnell,  the  conditions  to vesting of
restricted  shares  previously  awarded to Messrs.  Parsons and Purnell were not
waived by the Board at such time.

Compensation  of the Chief  Executive  Officer.  The  foregoing  principles  and
- ----------------------------------------------
policies were applied in determining the  compensation of Mr. Parsons,  Chairman
of the Board and Chief Executive Officer of American Mobile through 1998. During
fiscal 1998, Mr. Parsons  received a base salary of $350,000.  The  Compensation
and Stock Option  Committee also awarded Mr. Parsons options to purchase a total
of 50,000 shares of the Company's common stock.

Tax Deductibility of Executive Compensation.  The Internal Revenue Code of 1986,
- -------------------------------------------
as  amended  (the  "Code"),  limits the  federal  income  tax  deductibility  of
compensation  paid to the Company's chief  executive  officer and to each of the
other four most highly compensated  Executive  Officers.  The Company may deduct


                                       12

<PAGE>


such   compensation  only  to  the  extent  that  during  any  fiscal  year  the
compensation  does not exceed $1 million or meets certain  specified  conditions
(such as  stockholder  approval).  Based on the Company's  current  compensation
plans and policies and recently released regulations  interpreting the Code, the
Company and the Compensation  and Stock Option  Committee  believe that, for the
near future, there is little risk that the Company will lose any significant tax
deduction  for  executive  compensation.   The  Compensation  and  Stock  Option
Committee intends to monitor this issue, and will consider  modifications of the
Company's  compensation  policies  as  conditions  warrant  and  to  the  extent
necessary to serve the best interests of the Company.

Compensation and Stock Option Committee Interlocks and Insider Participation
- ----------------------------------------------------------------------------

During the fiscal year ended  December  31,  1998,  the  Compensation  and Stock
Option  Committee of American  Mobile's Board of Directors  consisted of Messrs.
Quartner,  Shaw  and  Smith.  During  1998,  the  Company  and  certain  of  its
subsidiaries   entered  into  contracts  and  other  transactions  with  certain
affiliates of Hughes.  All of these contracts and transactions  were approved by
American  Mobile's  Board of Directors or Executive  Committee,  and the Company
believes that the contracts and transactions were made on terms substantially as
favorable to the Company as could have been  obtained  from  unaffiliated  third
parties. The following is a description of such contracts and transactions.

In January 1997,  the Company  reached an agreement  with Hughes  Aircraft,  the
manufacturer of the Company's  satellite (the  "Satellite"),  to reduce by 27.5%
the  amount  of  certain  performance  payments  owed by the  Company  to Hughes
Aircraft  under its  Satellite  construction  contract and to defer all payments
otherwise  due  until  January  1998,  based on  certain  satellite  performance
considerations.  Thereafter,  certain additional contractual payment issues were
raised by the Company. At present,  the Company's  obligation to make additional
performance payments to Hughes Aircraft remains at issue and ongoing discussions
are underway between the companies.

Hughes Network Systems Limited  ("HNS"),  the manufacturer of the Company's land
earth stations (each an "LES") has provided AMSC Subsidiary software maintenance
services in support of the  operation  of the LESs at an annual rate of $760,000
for the twelve month period commencing December 1, 1998.

The  Company  has  entered  into  a  reseller  agreement  with  Hughes  Space  &
Communications Company,  through its Hughes Government Services ("HGS") business
unit, whereby American Mobile will sell the Company's services to HGS for resale
by HGS to federal government subscribers at rates to be established by HGS. Like
the  Company's  other  government  resellers,  HGS will set rates and prices for
services and equipment,  respectively  and will be  responsible  for billing and
collecting amounts due from its customers.

In connection with the Acquisition,  the Company,  AMSC Acquisition  Company and
its  subsidiaries  entered into agreements with Morgan Guaranty Trust Company of
New  York,Toronto  Dominion  Bank,  Bank of America  National  Trust and Savings


                                       13

<PAGE>



Association and certain other lenders (collectively, the "Banks") to provide for
two facilities:  (i) the Revolving  Credit  Facility,  a $100 million  unsecured
five-year reducing revolving credit facility and (ii) the Term Loan Facility,  a
$100 million five-year,  term loan facility with up to three additional one-year
extensions subject to the Banks' approval (collectively,  the "Bank Financing").
The Term Loan Facility is secured by the assets of the Company,  principally its
stockholdings  in XM Radio and AMSC  Acquisition  Company,  which was  formed in
connection with the Acquisition.  The Bank Financing is severally  guaranteed by
Hughes,  Singapore Telecom and Baron Capital Partners, L.P.  (collectively,  the
"Bank Facility Guarantors").

In exchange for the additional risks undertaken by the Bank Facility  Guarantors
in connection  with the Bank Financing,  American  Mobile agreed,  pursuant to a
Guaranty Issuance  Agreement dated March 31, 1998 (the "GIA"), to compensate the
Bank  Facility  Guarantors,  principally  in the  form of 1  million  additional
warrants and repricing of 5.5 million warrants previously issued (together,  the
"Guarantee  Warrants").  As originally  issued,  the  Guarantee  Warrants had an
exercise price of $12.51.  Further, in connection with the guarantees,  American
Mobile agreed to reimburse  the Bank  Facility  Guarantors in the event that the
Guarantors  were required to make payment under the  Revolving  Credit  Facility
guarantees and, in connection with this reimbursement  commitment,  has provided
the Bank  Facility  Guarantors a junior  security  interest  with respect to the
assets  of the  Company,  principally  its  stockholdings  in XM Radio  and AMSC
Acquisition Company.

The Bank  Facility  Guarantors  also  obtained  certain  demand  and  piggy-back
registration  rights with  regard to the  unregistered  shares of the  Company's
common stock held by them or issuable upon  exercise of the Guarantee  Warrants.
Pursuant to the terms of the Amended and Restated  Registration Rights Agreement
among the Bank Facility  Guarantors  and the Company (the  "Registration  Rights
Agreement"), the Company has agreed to (i) extend the expiration date for demand
registration  rights  with  respect to the Bank  Facility  Guarantors'  existing
warrants,  (ii) provide  registration rights for the warrants issued pursuant to
the GIA, and (iii) provide  registration rights for other restricted  securities
held by the Guarantors.  Under the Registration  Rights Agreement the Guarantors
would be entitled to up to three demand registrations with respect to its shares
of American Mobile's common stock,  subject to certain  registration  priorities
and postponement  rights of American Mobile. In addition the Guarantors would be
entitled to  piggyback  registration  in  connection  with any  registration  of
securities by American Mobile  (whether or not for its own account),  subject to
certain Motorola priorities for sale under the Participation Rights Agreement.

On March 29, 1999,  the Bank  Facility  Guarantors  agreed to eliminate  certain
covenants  contained  in the  GIA  relating  to the  Company's  Earnings  Before
Interest,  Depreciation,  Amortization and Taxes ("EBITDA") and service revenue.
In exchange for this waiver,  the Company  agreed to amend the exercise price of
the Guarantee Warrants from $12.51 per share to $7.50 per share.

Performance Graph
- -----------------

     The graph set forth below shows the  cumulative  total return to holders of
the  Company's  common stock from  December 31, 1993 through  December 31, 1998,
computed by dividing (1) the  difference  between the closing price per share at
the  beginning of such period and the last trading day of each month during such
period (the Company did not declare or pay  dividends on its common stock during
such period) by (2) the closing share price at the beginning of such period, and
compares  such  return to the  performance  during such period of the Center for
Research in Security  Prices  ("CRSP")  Total  Return Index for The Nasdaq Stock
Market (U.S.  Companies) ("Nasdaq U.S.") and the CRSP Nasdaq  Telecommunications
Stock Index ("Nasdaq  Telecom").  The Nasdaq U.S.  index  comprises all domestic
common  shares  traded on the Nasdaq  National  Market  and the Nasdaq  SmallCap
Market,  and the Nasdaq Telecom index  comprises all such domestic common shares
of companies  falling under Standard  Industrial  Classification  Code 48. These
indices are prepared for Nasdaq by the CRSP at the  University  of Chicago.  The
graph assumes $100  invested on December 31, 1993 in the Company's  common stock
(at $20.50 per share), the Nasdaq U.S. index and the Nasdaq Telecom index.

                     2. AMENDMENTS TO STOCK OPTION PLAN FOR
                     --------------------------------------
                             NON-EMPLOYEE DIRECTORS
                             ----------------------

Proposed Amendments
- -------------------

The Board of  Directors  has  approved  and  recommends  to the  stockholders  a
proposal  to amend  the  Company's  1994  Stock  Option  Plan  for  Non-Employee
Directors to provide for: (i) an increase in the size of the  automatic  initial
grant of options to new Eligible  Directors  from 1,000 shares to 5,000  shares,
and an  increase  in the  size of the  automatic  annual  grant  of  options  to
continuing  Eligible Directors from 500 shares to 2,500 shares; (ii) an increase
in the number of authorized  shares  available  for issuance  under the Director
Plan from 50,000 to 100,000; and (iii) the discretionary  granting of additional
options to Eligible Directors.

Subject to  stockholder  approval  of the  foregoing  amendments,  the Board has
approved the grant of options to purchase up to 45,000 shares of common stock in
the aggregate to the Eligible Directors, effective as of March 25, 1999.

The Director Plan is intended to promote ownership by non-employee  directors of
a greater proprietary interest in the Company,  thereby aligning such directors'
interests more closely with the interests of stockholders of the Company, and to
assist the Company in attracting,  and retaining,  highly  qualified  persons to
serve as non-employee  directors.  The amendments to the Director Plan set forth
above will not be effective unless or until stockholder approval is obtained.


Reasons for the Amendments
- --------------------------

The Board of Directors believes that the proposed amendments are necessary for a
number of reasons.  First, the Director Plan was initially  adopted in 1994, and
there has been no increase in the size of the automatic  grants since that time.
The Board believes that the size of the automatic option grants for non-employee
directors are relatively  small, in light of the Company's  growth and evolution
since  1994,  and  also  compared  with  the size of  automatic  grants  made to
non-employee directors under similar plans adopted by peer companies.

Second, the Board believes that the increase in the size of the automatic grants
is necessary to enable the Company to continue to attract, and retain, qualified
and dedicated  business  people to serve as  non-employee  directors.  The Board
believes  that  there is  significant  competition  for  qualified  non-employee
directors, and, accordingly,  the Board believes it is important to increase the
financial  incentive for such persons to agree to serve,  and continue to serve,
on the Company's Board of Directors.

Third,  the  increase  in the  size  of  automatic  grants,  if  approved,  will
necessitate  an increase in the number of shares  authorized  to be issued under
the Director Plan.  The Board  believes that an increase from 50,000  authorized
shares to 100,000 authorized shares is appropriate and prudent.


                                       18

<PAGE>



Finally,  the Board believes that the added  flexibility  to make  discretionary
grants of additional  options is necessary to recognize extra efforts on special
projects made by individual  non-employee  directors  from time to time, or over
the course of a longer period of time.

Terms of the Director Plan
- --------------------------

Pursuant to the Director  Plan,  each  Eligible  Director  received an option to
purchase  1,000 shares of common stock upon joining the Board of Directors,  and
each Eligible Director  continually  serving on the Board has received an option
to purchase 500 shares of common stock each year.  As of March 31, 1999, a total
of 10,000  options have been granted under the Director Plan (not  including the
grants  referred  to above that were made by the Board  subject  to  stockholder
approval at the 1999 annual  stockholders  meeting).  The options that have been
granted under the Director  Plan have exercise  prices that range from $9.73 per
share to $25.75 per share. The options granted under the Director Plan are fully
vested and exercisable on the date of grant.  Each option expires on the earlier
of (i) ten (10) years  from the date of grant or (ii)  seven (7) months  after a
director's termination of service as a director.

The optionee may not transfer options granted under the Director Plan, except by
will or the applicable laws of descent and distribution or pursuant to the terms
of a qualified domestic relations order. If, during the term of an option, there
is any  increase  or  decrease  in the number of issued  shares of common  stock
resulting  from a split-up or  consolidation  of shares or any  similar  capital
adjustment, or the payment of any stock dividend, the number and class of shares
covered by an outstanding  option and the exercise price per share of the option
will be proportionately adjusted.


Tax Consequences
- ----------------

The material federal income tax consequences to the Company and the non-employee
director of the grant and exercise of options  granted  under the Director  Plan
under the existing  applicable  provisions of the Internal Revenue Code of 1986,
as amended  (the "Code") and  regulations  thereunder  are  described in summary
fashion below. This description is a summary only.

An  optionee  will not  recognize  income on the grant of a  nonstatutory  stock
option,  but  generally  will  recognize  ordinary  income on the  exercise of a
nonstatutory  stock option.  The amount of income  recognized on the exercise of
such stock  option  generally  will be equal to the excess,  if any, of the fair
market value of the shares at the time of exercise over the  aggregate  exercise
price paid for the shares,  regardless of whether the exercise  price is paid in
cash or shares.  The Company  generally  will be entitled to a deduction  in the
amount of ordinary  income so recognized,  subject to satisfying  certain income
tax reporting requirements.

Vote Required
- -------------

The  affirmative  vote of a majority  of the shares of common  stock  present in
person or  represented  by proxy and  entitled to vote at the annual  meeting is
required to approve the adoption of the amendments to the Director Plan.

                                       19

<PAGE>




         The Board of Directors  unanimously  recommends that  stockholders vote
         FOR approval of the proposed amendments to the Director Plan.



                  3. RATIFICATION OF APPOINTMENT OF ACCOUNTANTS
                  ---------------------------------------------

On the  recommendation  of the  Audit  Committee,  the  Board of  Directors  has
appointed Arthur Andersen LLP as independent accountants for the Company for the
year 1999,  subject to ratification  by the  stockholders at the annual meeting.
Arthur Andersen LLP have been the independent  accountants for the Company since
1988.  A  representative  of Arthur  Andersen  LLP will be present at the annual
meeting of stockholders with the opportunity to make a statement if he or she so
desires and to respond to appropriate questions.

         The Board of Directors  unanimously  recommends a vote FOR ratification
         of the  appointment of Arthur  Andersen LLP as independent  accountants
         for the Company for the year 1999.




             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
             -------------------------------------------------------

Under the securities  laws of the United States,  the Company's  directors,  its
executive  officers,  and any  persons  holding  more  than ten  percent  of the
Company's  common stock are required to report their  ownership of the Company's
common stock and any changes in that  ownership to the  Securities  and Exchange
Commission (the "SEC") and the National Association of Securities Dealers,  Inc.
Specific due dates for these reports have been established by the Securities and
Exchange  Commission  and the  Company  is  required  to  report  in this  proxy
statement  any failure to file by these  dates.  No person  associated  with the
Company  who was  required  to file under  these  rules  failed to file any such
required report in 1998. In making this statement, the Company has relied on the
written  representations of its directors and officers and copies of the reports
that have been filed with the SEC.


                                  OTHER MATTERS
                                  -------------

The Board of Directors is not aware of any other  matters to be presented at the
annual  meeting.  If any other matter proper for action at the meeting should be
presented,   the  holders  of  the  accompanying  proxy  will  vote  the  shares
represented by the proxy on such matter in accordance  with their best judgment.
If any matter not proper for  action at the  meeting  should be  presented,  the
holders of the proxy will vote against consideration thereof or action thereon.

All shares represented by the accompanying  proxy, if the proxy is duly executed
and  received  by the Company at or prior to the  meeting,  will be voted at the
meeting in accordance with any

                                       21

<PAGE>


instructions specified on such proxy and, where no instruction is specified,  as
indicated on such proxy.


               PROPOSALS FOR THE COMPANY'S ANNUAL MEETING IN 2000
               --------------------------------------------------

The Company will review for inclusion in next year's proxy statement stockholder
proposals  received  by  December  22,  1999.  Proposals  should  be sent to the
Secretary  of  the  Company,   10802  Parkridge  Boulevard,   Reston,   Virginia
20191-5416.  In order to be  included  in the proxy  statement  for next  year's
annual meeting,  such proposals must comply with all of the requirements of Rule
14a-8 under the Securities Exchange Act of 1934 (the "Exchange Act").

A stockholder who wishes to submit a proposal for inclusion in next year's proxy
statement,  outside the processes of Rule 14a-8 under the Exchange Act, must, in
accordance with Article II, Section 13 of the Company's By-Laws,  file a written
notice with the Secretary of the Company which conforms to the  requirements  of
the By-Laws. If the Board of Directors or a designated  committee or officer who
will  preside  at the  stockholders  meeting  determines  that  the  information
provided in such notice does not satisfy the  informational  requirements of the
By-Laws or is otherwise  not in  accordance  with law, the  stockholder  will be
notified  promptly of such  deficiency  and be given an  opportunity to cure the
deficiency  within the time period  prescribed  in the ByLaws.  Such notice of a
stockholder  proposal  must be delivered not less than 60 days nor more than 120
days prior to the date of the annual  meeting  to be held in 2000  (unless  such
notice  relates to a special  meeting or the annual meeting is called to be held
before the date specified in the By-Laws, in which case the stockholder proposal
must be delivered no later than the close of business on the tenth day following
the date on which notice of the meeting is publicly announced).  Any stockholder
proposal that is not submitted in accordance with the foregoing  procedures will
not be considered to be properly brought before the 2000 annual meeting, and, if
presented  at the meeting,  the Company will be able to use proxies  given to it
for such meeting to vote for or against any such proposal at the Company's  sole
discretion.
