                               MOTIENT CORPORATION
                          EXECUTIVE RETENTION AGREEMENT


     THIS EXECUTIVE RETENTION AGREEMENT is entered into as of July 16, 2002 (the
"Effective Date"), by and between Motient Corporation, a Delaware corporation
(the "Company"), and Walter V. Purnell, Jr. (the "Executive").

     WHEREAS, the Executive is currently employed by the Company and is an
executive officer of the Company; and

     WHEREAS, the Company wishes to implement a severance program for the
Executive and wishes to document under this Agreement the provisions applicable
to the Executive in the event of his or her termination of employment.

     NOW THEREFORE, in consideration of the Executive's acceptance of and
continuance in Executive's employment, the parties agree to be bound by the
terms contained in this agreement as follows:

     1. "At-Will" Employment. The Company may terminate the Executive's
employment at any time for any reason pursuant to a Notice of Termination. The
Executive may terminate his or her employment with the Company at any time for
any reason pursuant to a Notice of Termination. If the Executive dies while
still an employee of the Company, the Executive's death shall be a termination
of employment from the Company. Any termination of the Executive's employment by
the Company or the Executive (other than because of the Executive's death) shall
be communicated by written Notice of Termination to the other party hereto in
accordance with Section 5.2 below. For purposes of this Agreement, a "Notice of
Termination" shall mean a notice which shall indicate the specific termination
provision in this Agreement relied upon, if any, and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Executive's employment under the provision so indicated. The
Company's notice shall be given in writing by the Chairman of the Company's
Board of Directors. Termination of the Executive's employment shall take effect
on the Date of Employment Termination, the setting of which shall require the
minimum notice period described under the definition of "Date of Employment
Termination." Termination of the Executive's employment shall occur on the
specified Date of Employment Termination even if there is a dispute between the
parties hereof relating to the provisions of this Agreement applicable to such
termination.

     2. Compensation Upon Termination.

     2.1 Death. If the Executive's employment is terminated as a result of the
Executive's death, the Company shall pay to the Executive's estate, or as
may be directed by the legal representatives of such estate, the Executive's
then current base salary through the Date of Employment Termination and all
other unpaid amounts, if any, to which Executive is entitled as of the Date of
Employment Termination. The payments contemplated by this Section 2.1 shall be
paid at the time they are due, and the Company shall have no further obligations
to the Executive or his or her estate under this Agreement.


                                       1

     2.2 Disability. If the Company terminates the Executive's employment
because of the Executive's Disability, the Company shall pay the Executive the
Executive's then current base salary through the Date of Employment Termination
and all other unpaid amounts, if any, to which Executive is entitled as of the
Date of Employment Termination. The payments contemplated by this Section 2.2
shall be paid at the time they are due, and the Company shall have no further
obligations to the Executive under this Agreement; provided, however, that the
base salary shall be reduced by the amount of any disability benefit payments
made to the Executive during a period of Disability from any insurance or other
policies provided by the Company.

     2.3 By the Company for Cause or by the Executive without Good Reason. If
the Executive's employment with the Company is terminated in accordance with
this Section 2.3, the Company shall pay the Executive the Executive's then
current base salary through the Date of Employment Termination and all other
unpaid amounts, if any, to which Executive is entitled as of the Date of
Employment Termination. The Executive's termination is covered by this Section
2.3, (i) if the Executive terminates his or her employment other than for Good
Reason, or (ii) if the Company terminates the Executive's employment for Cause.
The payments contemplated by this Section 2.3 shall be paid at the time such
payments are due, and the Company shall have no further obligations to the
Executive under this Agreement.

     2.4 By the Company other than for Cause or by the Executive for Good
Reason. If the Company terminates the Executive's employment other than for
Cause or the Executive voluntarily terminates his or her employment for Good
Reason, the Company shall pay the Executive the Executive's then current base
salary through the Date of Employment Termination and all other unpaid amounts,
if any, to which the Executive is entitled as of the Date of Employment
Termination, plus the following amounts:

     (a) Severance Amount. The Executive shall receive a severance payment equal
to eighteen months of the Executive's Reference Compensation. This severance
payment amount shall be paid in installments in accordance with the Company's
normal payroll schedule for active employees; provided, however, that the
severance payment amount shall not be paid prior to the Company's receipt of a
duly executed Waiver and Release Agreement that is not revoked during the
applicable regulatory revocation period.

     3. Waiver and Release Agreement. In consideration of the severance payments
described in Section 2.4, to which severance payments the Executive would
otherwise not be entitled, and as a pre-condition to the Executive becoming
entitled to such severance payments under this Agreement, the Executive agrees
to execute at the time of Executive's termination a Waiver and Release Agreement
in exactly the form provided to the Executive by the Company without alteration
or addition (the "Waiver and Release Agreement"), attached hereto as Exhibit A,
the terms and conditions of which are specifically incorporated herein by
reference.

     4. Non-Compete Agreement. In consideration of the severance payments
described in Section 2.4, to which severance payments the Executive would
otherwise not be entitled, and as a pre-condition to the Executive becoming
entitled to such severance payments under this Agreement, the Executive agrees
to execute at the time of Executive's termination a Non-Compete and Non-Solicit
Agreement in exactly the form provided to the Executive by the Company without
alteration or addition (the "Non-Compete Agreement") attached hereto as Exhibit
B, the terms and conditions of which are specifically incorporated herein by
reference.

     5. Miscellaneous.

     5.1 No Mitigation. The Company agrees that, if the Executive's employment
by the Company is terminated in a manner that results in the payment of
severance under Section 2.4, the Executive shall not be required to seek other


                                       2
<PAGE>

employment or to attempt in any way to reduce any amounts payable to the
Executive by the Company pursuant to this Agreement. Further, the amount of any
payment or benefit provided for under this Agreement shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

     5.15. Definitions.

     "Cause" means:

     (a) the willful and continued failure of the Executive to substantially
perform the Executive's duties with the Company (other than any such failure
resulting from incapacity due to physical or mental illness), after a written
demand for substantial performance is delivered to the Executive by the Board of
the Company, which demand specifically identifies the manner in which the Board
believes that the Executive has not substantially performed the Executive's
duties;

     (b) the willful engaging by the Executive in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company,
monetary or otherwise;

     (c) personal dishonesty or breach of fiduciary duty to the Company that in
either case results or was intended to result in personal profit to the
Executive at the expense of the Company; or

     (d) willful violation of any law, rule or regulation (other than traffic
violations, misdemeanors or similar offenses) or cease-and-desist order, court
order, judgment or supervisory agreement, which violation is materially and
demonstrably injurious to the Company.

     For purposes of the preceding clauses, no act or failure to act, on the
part of the Executive, shall be considered "willful" unless it is done, or
omitted to be done, by the Executive in bad faith and without reasonable belief
that the Executive's action or omission was in the best interests of the
Company. Any act, or failure to act, based upon prior approval given by the
Board or upon the instructions or with the approval of the Executive's superior
or based upon the advice of counsel for the Company, shall be conclusively
presumed to be done, or omitted to be done, by the Executive in good faith and
in the best interests of the Company. The cessation of employment of the
Executive shall not be deemed to be for Cause unless and until there shall have
been delivered to the Executive, as part of the Notice of Termination, a copy of
a resolution duly adopted by the affirmative vote of not less than
three-quarters (3/4) of the entire membership of the Board at a meeting of the
Board called and held for the purpose of considering such termination (after
reasonable notice is provided to the Executive and the Executive is given an
opportunity, together with counsel, to be heard before the Board) finding that,
in the good faith opinion of the Board, the Executive is guilty of the conduct
described in clause (a), (b), (c), or (d) above, and specifying the particulars
thereof in detail.

     "Code" means the Internal Revenue Code of 1986, as amended from time to
time.

     "Date of Employment Termination" means (i) if the Executive's employment is
terminated by the Executive's death, the date of the Executive's death; (ii) if
the Executive's employment is terminated because of the Executive's Disability,
30 days after Notice of Termination, provided that the Executive shall not have
returned to the performance of the Executive's duties on a full-time basis
during such 30-day period; (iii) if the Executive's employment is terminated by
the Company for Cause, the date immediately following the Notice of Termination;
(iv) if the Executive's employment is terminated by the Company other than for
Cause, 30 days after the Notice of Termination; or (v) if the Executive
voluntarily terminates his or her employment, the date 15 days after the Notice
of Termination.

     "Disability" means the Executive's inability to perform all of the
Executive's duties hereunder by reason of illness, physical or mental disability
or other similar incapacity, as determined by the Chief Executive Officer in his
or her sole discretion, which inability shall continue for more than three
consecutive months; provided, however, that the Executive does not hereby waive
any rights under the Americans with Disabilities Act or other applicable law.

     "Good Reason" means the occurrence of any of the following events:


                                       5
<PAGE>

     (a) a reduction by the Company without the Executive's consent in the
Executive's annual base salary as in effect on the date hereof or as the same
may be increased from time to time; or

     (b) the Company's requiring the Executive without the Executive's consent
to be based at any office or location that is more than fifty (50) miles from
the Executive's then applicable office or location.

     "Reference Compensation" means the sum of the Executive's annual base
salary divided by twelve.

have caused this Agreement to be duly executed on their behalf, as of the day
and year first herein above written.

                                    EXHIBIT A
                          WAIVER AND RELEASE AGREEMENT


     This Waiver and Release Agreement is in consideration of the severance pay
and benefits provided to me by Motient Corporation (the "Company"), in
accordance with that certain Agreement, dated as of July 16, 2002, by and
between me and the Company and providing for a severance payment, paid as a
continuation of salary, equal to 18 months of my base salary.

     The payments and benefits described above are referred to herein
collectively as the "Severance Payment." I acknowledge and agree that I would
not be entitled to the Severance Payment without entering into this Waiver and
Release Agreement, and I voluntarily enter into this Waiver and Release
Agreement.

     I, on my own behalf and on behalf of my heirs, executors, administrators,
attorneys and assigns, hereby unconditionally and irrevocably release, waive and
forever discharge the Company and each of its affiliates, parents, successors,
predecessors, and the subsidiaries, directors, owners, members, shareholders,
officers, agents, and employees of the Company and its affiliates, parents,
successors, predecessors, and subsidiaries (collectively all of the forgoing are
referred to as the "Employer"), from any and all causes of action, claims and
damages, including attorneys' fees, whether known or unknown, foreseen or
unforeseen, presently asserted or otherwise arising through the date of my
signing of the Waiver and Release Agreement, concerning my employment or
separation from employment. This release includes, but is not limited to, any
claim or entitlement to salary, bonuses, any other payments, benefits or damages
arising under any federal law (including but not limited to, Title VII of the
Civil Rights Act of 1964, the Age Discrimination in Employment Act, the Employee
Retirement Income Security Act of 1974 (namely, "ERISA"), the Americans with
Disabilities Act, and the Family and Medical Leave Act, each as amended); any
claim arising under any state or local ordinances or regulations; and any claim
arising under any common law principle or public policy, including but not
limited to all suits in tort or contract, such as, wrongful termination,
defamation, emotional distress, invasion of privacy or loss of consortium.
Notwithstanding the preceding, this Waiver and Release agreement shall not apply
with respect to a claim under ERISA for benefits accrued but not paid under an
ERISA Plan.

     I understand that by signing this Waiver and Release Agreement I am not
waiving any claims or administrative charges which cannot be waived by law. I am
waiving, however, any right to monetary recovery or individual relief should any
federal, state or local agency (including the Equal Employment Opportunity
Commission (the "EEOC")) pursue any claim on my behalf arising out of or related
to my employment with and/or separation from employment with the Employer.

     I further agree, without any reservation whatsoever, never to sue the
Employer or become a party to a lawsuit on the basis of any and all claims of
any type lawfully and validly released in this Waiver and Release Agreement. If
I sue in violation of the preceding sentence of this Waiver and Release
Agreement, I will (1) pay all costs and expenses incurred by the Employer in
defending against a suit or enforcing this Waiver and Release Agreement,
including litigation and court costs, expenses and reasonable attorneys' fees,
and (2) I will repay the Severance Payment I received in consideration for this
Waiver and Release Agreement.

     I am signing this Waiver and Release Agreement knowingly and voluntarily. I
acknowledge that:

                                      A-1

<PAGE>


         (1)      I am hereby advised in writing to consult an attorney before
                  signing this Waiver and Release Agreement;

         (2)      I have relied solely on my own judgment and/or that of my
                  attorney regarding the consideration for and the terms of this
                  Waiver and Release Agreement and am signing this Waiver and
                  Release Agreement knowingly and voluntarily of my own free
                  will;

         (3)      I am not entitled to the Severance Payment amount unless I
                  agree to and honor the terms of this Waiver and Release
                  Agreement.

         (4)      I have been given at least forty-five (45) days to consider
                  this Waiver and Release Agreement;

         (5)      I may revoke this Waiver and Release Agreement within seven
                  (7) days after signing it by submitting a written notice of
                  revocation to the Company's Human Resources Director, Scott
                  Oliphant. I further understand that this Waiver and Release
                  Agreement is not effective or enforceable until after the
                  seven (7) day period of revocation has expired without
                  revocation, and that if I revoke this Waiver and Release
                  Agreement, I will not receive any Severance Payment;

         (6)      I have read and understand the Waiver and Release Agreement
                  and further understand that it includes a general release of
                  any and all known and unknown, foreseen or unforeseen, claims
                  presently asserted or otherwise arising through the date of my
                  signing of this Waiver and Release Agreement that I may have
                  against the Employer; and

         (7)      No statements or conduct by the Employer have in any way
                  coerced or unduly influenced me to execute this Waiver and
                  Release Agreement.

     I further acknowledge that there are no other agreements of any nature
between the Employer and me with respect to the matters discussed in this Waiver
and Release Agreement, except as expressly stated herein, and that in signing
this Waiver and Release Agreement, I am not relying on any agreements or
representation, except those expressly contained in this Waiver and Release
Agreement and the Retention Agreement.

     I further acknowledge and agree that if any provision of this Waiver and
Release Agreement is found, held or deemed by a court of competent jurisdiction
to be void, unlawful or unenforceable under any applicable statute or
controlling law, the remainder of this Waiver and Release Agreement shall
continue in full force and effect.

     This Waiver and Release Agreement is deemed made and entered into in the
Commonwealth of Virginia, and in all respects shall be interpreted, enforced and
governed under applicable federal law, and in the event that any reference shall
be made to state law, the internal laws of the Commonwealth of Virginia shall
apply. Any disputes under this Waiver and Release Agreement shall be adjudicated
by a court of competent jurisdiction in the State of California.


     I understand that, to receive the Severance Payment amount, I must sign and
return this Waiver and Release Agreement no sooner than my employment
termination date and no later than forty-five (45) days from the date my
employment was terminated.

                                    EXHIBIT B
                      NON-COMPETE AND NON-SOLICIT AGREEMENT

     THIS NON-COMPETE AND NON-SOLICIT AGREEMENT ("Agreement") is entered into
between Motient Corporation (the "Company") and myself, the undersigned employee
of the Company effective as of the execution date set forth below. In
consideration of the severance payments to be provided to me under that certain
Agreement, dated as of July 16, 2002, by and between the Company and me, the
sufficiency of which I expressly acknowledge, the Company and I hereby agree,
intending to be legally bound, as follows:

1.   Employee Obligations
     1.1. No Solicitation of Employees. For twelve (12) months after my
employment with the Company is terminated, whether voluntarily or involuntarily,
I agree not to solicit, directly or indirectly, any of the Company's key
employees for employment with a person or entity involved in marketing or
developing products or services competitive with the Company's products or
services. Key employees include supervisory personnel, executives, personnel in
charge of any department, section or subdivision within the Company and project,
contract managers (or directors) and senior personnel on any individual project
or projects.

     1.2. No Unfair Competition. During my employment with the Company and for a
period of 18 months after the termination of my employment with the Company,
whether voluntarily or involuntarily, I agree that I shall not, directly or
indirectly, engage in or become interested in any Competing Business, in
connection with research, development, consulting, manufacturing, purchasing,
accounting, engineering, marketing, merchandising or selling of any product or
service which resembles or competes with a product or service of the Company
(hereafter, such engagement referred to as "Improper Engagement"). I understand
that I will have engaged in or become interested in a Competing Business if,
whether or not I am compensated, I become an employee, consultant, advisor or
agent of a Competing Business. I also understand that I will have entered into
an Improper Engagement if I become a stockholder owning beneficially or of
record more than five percent (5%) of the outstanding shares of any class of
stock of a Competing Business or a director, partner, joint venturer or
proprietor of a Competing Business. For purposes of this Agreement, a "Competing
Business" is an enterprise engaged in or about to become engaged in, research on
or development, production, marketing or selling of any product or service which
resembles or competes with a product or service of the Company.

     1.3 Fiduciary Duty not to Disclose Proprietary or Confidential Information.
During and after my employment with the Company, I agree to observe the terms of
the Intellectual Property and Confidential Information Agreement, which I
entered into with the Company upon accepting employment with the Company. I
understand and agree that, during and after my employment with the Company, I
shall hold in a fiduciary capacity for the benefit of the Company all secret or
confidential information, knowledge or data relating to the Company or its
affiliated companies and their respective businesses that I have obtained during
the course of my employment by the Company or any of its affiliate companies
that is not public knowledge.

     2. Nature of Relationship
     Nothing herein shall be construed as constituting an agreement,
understanding or commitment of any kind that the Company shall continue to
employ me, nor shall this Agreement limit in any way the Company's right to
terminate my employment at any time for any reason whatsoever, subject to
applicable laws and contracts.

     3. Enforcement
     I acknowledge that in the event of my breach of any of the obligations in
this Agreement, the Company's business interests will be irreparably injured,
the full extent of the Company's damages will be impossible to ascertain,
monetary damages will not be an adequate remedy for the Company,


                                       A-2

and the Company will be entitled to enforce this Agreement by an injunction or
other equitable relief, without the necessity of posting bond or security, which
I expressly waive. I understand that the Company may waive some of the
requirements expressed in this Agreement, but that such a waiver to be effective
must be made in writing by the Company senior management and should not in any
way be deemed a waiver of the Company's right to enforce any other requirements
or provisions of this Agreement. I agree that each of my obligations specified
in this Agreement is a separate and independent covenant that shall survive any
termination of this Agreement and that the unenforceability of any of them shall
not preclude the enforcement of any other covenants in this Agreement.

     4. General Terms
     This is my entire agreement with the Company with respect to its subject
matter and its date, superseding any prior oral or written, express or implied
negotiations and agreements, and its terms will be governed by the laws of the
Commonwealth of Virginia without regard to conflict of laws provisions. The
agreement may not be changed in any respect except by a written agreement signed
by both myself and an officer of the Company. If any provision of the agreement
is held to be invalid, illegal or unenforceable for any reason, the validity,
legality and enforceability of the remaining provisions will not in any way be
affected or impaired thereby.

     By my signature below, I acknowledge that I have reviewed this Non-Compete
and Non-Solicit Agreement carefully and understand that the covenants and
obligations it contains are binding on me.
