expenses incurred by EMPLOYEE in connection with travel on XM business. As

shall be approved in advance by XM in accordance with and subject to the terms
and conditions of XM's


                                       3

then-prevailing expense policy. As a condition precedent to obtaining
reimbursement of expenses, EMPLOYEE shall provide to XM any and all statements,
bills, or receipts evidencing the expenses for which EMPLOYEE seeks
reimbursement, and such related information or materials as XM may from time to
time reasonably require. EMPLOYEE shall account to XM for any expenses that are

administrative support relating to the performance of EMPLOYEE's duties of the
same type and at least the same extent as is provided to other executive
employees. XM shall acquire and/or provide to EMPLOYEE for his business use: a

various trade books. Such items shall remain the exclusive property of XM, are
to be used solely for XM's benefit, and shall be returned promptly to XM upon
request at the termination of EMPLOYEE's employment for whatever reason.

notwithstanding, all payments required to be made by XM hereunder to EMPLOYEE or
EMPLOYEE's estate or beneficiaries in connection with EMPLOYEE's employment

as XM may reasonably determine it should withhold pursuant to any applicable law
or regulation.

second anniversary of the grant, and one third of the shares covered by the
option shall become exercisable on the third anniversary of the grant. In the
event that EMPLOYEE holds non-vested options at the time his


                                       4

employment by XM terminates, such non-vested options shall vest or shall be
forfeited, as the case may be, in accordance with the provisions of Article 4
hereof.

         (d) Vested options may be exercised within ten (10) years of the date

         (a) Upon EMPLOYEE's Disability, the payment of benefits under XM's
short-term and long-term disability insurance programs, if any, shall offset
XM's obligations under Article 3.1 hereof to the extent such benefits are
received by EMPLOYEE.

         (b) Subject to any applicable legal requirements, in the event EMPLOYEE

shall be entitled to exercise any of his vested options within eighteen (18)
months after termination.

         (f) If, as a result of a Change of Control, it is determined that
EMPLOYEE would be subject to the excise tax imposed by Section 4999 of the
Internal Revenue Code, XM shall reimburse EMPLOYEE for the amount of such tax,
and shall pay EMPLOYEE such additional amount as may be necessary to place
EMPLOYEE in the same financial position that he would have been in if he had not
incurred such excise tax liability. All determinations under this Article
4.5(f), including whether EMPLOYEE is liable for the excise tax, and the amount
to be paid to EMPLOYEE by XM, shall be made by a nationally-recognized

         4.6. EXPIRATION OF CONTRACT TERM.

         (a) For the purposes of this Agreement, Renewal Offer means a bona fide
offer by XM to enter into a new employment agreement with EMPLOYEE, on terms at
least as favorable to EMPLOYEE as this Agreement, made to EMPLOYEE at least four
(4) months before the expiration of this Agreement.

parties nevertheless do not enter into a new employment agreement and EMPLOYEE's
employment by XM therefore terminates upon the expiration of this Agreement, any
options scheduled to vest on the third anniversary of the Effective Date of this
Agreement pursuant to Article 3.7(c) shall immediately vest and become
exercisable, all other non-vested options shall be forfeited, and EMPLOYEE shall
be entitled to exercise any of his vested options within three (3) months after
termination.

         (c) In the event that XM does not make a Renewal Offer to Employee and
EMPLOYEE's employment by XM therefore terminates at the expiration of the term
of this Agreement, all options that have been granted to EMPLOYEE shall
immediately vest and become exercisable, and EMPLOYEE shall be entitled to
exercise any of his vested options within eighteen (18) months after
termination.

                                    ARTICLE 5
                              RESTRICTIVE COVENANTS

         5.1. CONFIDENTIALITY. Except as authorized or directed by XM, EMPLOYEE
shall not, at any time during or subsequent to the term of this Agreement,
directly or


                                       8

<Page>

indirectly publish or disclose any Confidential Information of XM or of any of
its Affiliates, or Confidential Information of others that has come into the
possession of XM or of any of its Affiliates, or into the EMPLOYEE's possession
in the course of his employment with XM or of his services and duties hereunder,
to any other person or entity, and EMPLOYEE shall not use any such Confidential
Information for EMPLOYEE's own personal use or advantage or make it available to
others for use. All Confidential Information, whether oral or written, regarding
the business or affairs of XM or any of its Affiliates, including, without
limitation, information as to their products, services, systems, designs,
inventions, software, finances (including prices, costs and revenues), marketing
plans, programs, methods of operation, prospective and existing contracts,
customers and other business arrangements or business plans, procedures, and
strategies, shall all be deemed Confidential Information, except to the extent
the same shall have been lawfully and without breach of the EMPLOYEE'S
confidentiality obligation made available to the general public without
restriction, or that EMPLOYEE can prove, by documentary evidence, was previously
known to EMPLOYEE prior to the term of EMPLOYEE's employment. The Company shall
be under no obligation to identify specifically any information as to which the
protection of this Section 5.1 extends by any notice or other action. Upon
expiration or termination of this Agreement for any reason, EMPLOYEE shall
promptly return to XM all Confidential Information, including all copies thereof
in EMPLOYEE's possession, whether prepared by him or others.

         5.2. UNFAIR COMPETITION. During his employment pursuant to this
Agreement and for a period of one (1) year after the termination of his
employment, EMPLOYEE shall not, within the United States, directly or
indirectly, and whether or not for compensation, as a stockholder owning
beneficially or of record more than five percent (5%) of the outstanding shares
of any class of stock of an issuer, or as an officer, director, employee,
consultant, partner, joint venturer, proprietor, or otherwise, engage in or
become interested in any Conflicting Organization in connection with research,
development, consulting, manufacturing, purchasing, accounting, engineering,
marketing, merchandising or selling of any Conflicting Product or Service,
directly or indirectly, in competition with XM or any of its Affiliates (or any
of their successors) as conducted from time to time during such period. During
the period in which EMPLOYEE is receiving any payments under this Agreement and
for a period of one (1) year thereafter, EMPLOYEE shall not, without the prior
written consent of XM, solicit or hire or induce the termination of employment
of any employees or other personnel providing services to XM, or any of its
Affiliates, for any business activity, other than a business activity owned or
controlled, directly or indirectly, by XM or any of its Affiliates.

         5.3. INJUNCTIVE RELIEF.

         (a) EMPLOYEE acknowledges and warrants that he will be fully able to
earn an adequate livelihood for himself and his dependents if Section 5.2 should
be specifically enforced against him, and that Section 5.2 merely prevents
unfair competition against XM for a limited period of time. EMPLOYEE agrees and
acknowledges that, by virtue of EMPLOYEE's employment with XM, EMPLOYEE shall
have access to and maintain an intimate knowledge of XM's activities and
affairs,


                                       9

<Page>

including trade secrets, Confidential Information, and other confidential
matters. As a result of such access and knowledge, and because of the special,
unique, and extraordinary services that EMPLOYEE is capable of performing for XM
or one of its competitors, EMPLOYEE acknowledges that the services to be
rendered by EMPLOYEE pursuant to this Agreement are of a character giving them a
peculiar value, the loss of which cannot adequately or reasonably be compensated
by money damages. Consequently, EMPLOYEE agrees that any breach or threatened
breach by EMPLOYEE of EMPLOYEE's obligations under this Article 5 would cause
irreparable injury to XM, and that XM shall be entitled to (i) preliminary and
permanent injunctions enjoining EMPLOYEE from violating such provisions, and
(ii) actual money damages suffered by XM as a result of such breach, in the
amount of any fees, compensation, benefits, profits, or other remuneration
earned by EMPLOYEE as a result of such breach, together with interest, and cost
and attorney's fees expended to collect such damages or secure such injunctions.
Nothing in this Agreement, however, shall be construed to prohibit XM from
pursuing any other remedy, XM and EMPLOYEE having agreed that all such remedies
shall be cumulative.

         (b) The restrictions set forth in this Article 5 and the following
Article 6 shall be construed as independent covenants, and shall survive the
termination or expiration of this Agreement, and the existence of any claim or
cause of action against XM, whether predicated upon this Agreement or otherwise,
shall not constitute a defense to the enforcement by XM of the restrictions
contained in this Article 5 or the following Article 6. EMPLOYEE hereby consents
and waives any objection to the jurisdiction over his person or the venue of any
courts within the State of Virginia with respect to any proceedings in law or in
equity arising out of this Article 5 or the following Article 6. If any court of
competent jurisdiction shall hold that any of the restrictions contained in
Section 5.2 are unreasonable as to time, geographical area, or otherwise, said
restrictions shall be deemed to be reduced to the extent necessary in the
opinion of such court to make their application reasonable.

                                    ARTICLE 6
                        INVENTIONS, WORKS OF AUTHORSHIP,
                             PATENTS AND COPYRIGHTS

         6.1. OWNERSHIP OF INVENTIONS AND WORKS OF AUTHORSHIP. EMPLOYEE agrees
that all Inventions made, conceived, discovered, developed or reduced to
practice by EMPLOYEE and all software and other works of authorship created by
EMPLOYEE, either alone or with others, at any time, within or without normal
working hours, during the term of this Agreement, arising out of such employment
or based upon Confidential Information, or pertinent to any field of business or
research in which, during such employment, XM is engaged or (if such is known or
ascertainable by EMPLOYEE) is considering engaging, whether or not patented or
patentable, shall be and remain the sole property of XM with respect to all
rights of EMPLOYEE arising from any discovery, conception, development,
reduction to practice, or creation by EMPLOYEE. XM shall have the full right to
assign, license, or transfer all rights thereto.

         6.2. DISCLOSURE OF INVENTIONS AND WORKS OF AUTHORSHIP. EMPLOYEE shall
promptly make full disclosure to XM or to an authorized representative thereof
of all information relating to the making, conception, discovery, development,
creation or reduction to practice of Inventions, or of software and other works
of authorship owned by XM pursuant to Section 6.1 above.

         6.3. PATENT AND COPYRIGHT APPLICATIONS. At the request of XM and at
XM's expense, EMPLOYEE shall execute such documents and perform such acts as XM
deems necessary to obtain patents or the like on such Inventions or copyright
registrations for such software and other works of authorship in any
jurisdiction or jurisdictions. Such obligation shall continue beyond the term of
this Agreement. In the event that XM is unable because of EMPLOYEE's mental or
physical capacity or for any other reason to secure EMPLOYEE's signature to
apply for or to pursue any applications for patent or copyright covering
Inventions, software and other works of authorship owned by XM pursuant to
Section 6.1, then EMPLOYEE hereby irrevocably designates and appoints XM as
EMPLOYEE's agent and attorney in fact, upon prior notice, to act for and in his
behalf and stead to execute and file any such applications and to do all other
lawfully permitted acts to further the prosecution and issuance of patents and
copyright registrations thereon with the same legal force and effect as if
executed by EMPLOYEE. EMPLOYEE further agrees not to file any patent
applications relating to or describing or otherwise disclosing any Confidential
Information or any such Inventions, or to claim any copyright or file any
applications to register any copyright in such software or other works of
authorship, except with the prior written consent of XM.

         6.4. ASSIGNMENT OF INVENTIONS AND WORKS OF AUTHORSHIP. EMPLOYEE agrees
to assign to XM or it Affiliates all of EMPLOYEE's right, title and interest in
and to any and all such Inventions and the patent applications and patents
relating thereto and to the copyright in any and all such software and other
works of authorship and any copyright applications and registrations relating
thereto conceived, reduced to practice, discovered, created or otherwise
developed by EMPLOYEE and owned by XM pursuant to Section 6.1 above.

                                    ARTICLE 7
                                  MISCELLANEOUS

         7.1. ASSIGNMENT. The rights and obligations of XM under this Agreement
shall be binding upon its successors and assigns and, subject to EMPLOYEE's
rights under Article 4.5 hereof, may be assigned by XM to the successors in
interest of XM. The rights and obligations of EMPLOYEE under this Agreement
shall be binding upon EMPLOYEE's heirs, legatees, personal representatives,
executors or administrators. This Agreement may not be assigned by EMPLOYEE, but
any amount owed EMPLOYEE upon EMPLOYEE's death shall inure to the benefit of
EMPLOYEE's heirs legatees, personal representatives, executors, or
administrators.

         7.2. NOTICE. For purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be

         7.3. ENTIRE AGREEMENT. From and after the Effective Date, this
Agreement constitutes the entire agreement between the parties hereto, and
expressly supersedes all prior oral or written agreements, commitments or
understandings with respect to the matters provided for herein.

         7.4. HEADINGS. Article and Section headings contained in this Agreement
are inserted for convenience of reference only, shall not be deemed to be a part
of this Agreement for any purpose, and shall not in any way define or affect the
meaning, construction or scope of any of the provisions hereof.

         7.5. SEVERABILITY. In the event any provision of this Agreement, or any
portion thereof, is determined by any arbitrator or court of competent
jurisdiction to be unenforceable as written, such provision or portion thereof
shall be interpreted so as to be enforceable. In the event any provision of this
Agreement, or any portion thereof is determined by any arbitrator or court of
competent jurisdiction to be void, the remaining portions of this Agreement
shall nevertheless be binding upon XM and EMPLOYEE with the same effect as
though the void provision or portion thereof had been severed and deleted.

         7.6. ARBITRATION. Without prejudice to XM's right to seek an injunction
pursuant to Article 5.3(a) hereof from a court of competent jurisdiction, any
dispute between the parties hereto arising out of this Agreement, or otherwise
arising out of or relating to EMPLOYEE's employment by XM, or the termination
thereof, shall be submitted to non-binding mediation before a mediator to be
agreed upon by the parties

                                       12

or, failing agreement, to be appointed by the American Arbitration Association
("AAA"). In the event that mediation is unsuccessful, such dispute shall be
resolved by binding arbitration, before a single arbitrator, under the rules of
the AAA. The arbitrator shall have the authority to apportion the costs of
arbitration, and to render an award including reasonable attorney's fees, as and
to the extent he deems appropriate under the circumstances.

         7.7. GOVERNING LAW. This Agreement, the rights and obligations of the
parties hereto, and any claims or disputes relating thereto, shall be governed
by and construed in accordance with the substantive laws of the State of
Virginia (excluding the choice of law rules thereof).

         7.8. AMENDMENT; MODIFICATION; WAIVER. No amendment, modification or
waiver of the terms of this Agreement shall be valid unless made in writing and
duly executed by EMPLOYEE and XM. No delay or failure at any time on the part of
EMPLOYEE or XM in exercising any right, power or privilege under this Agreement,
or in enforcing any provision of this Agreement, shall impair any such right,
power, or privilege, or be construed as a waiver of any default or as any
acquiescence therein, or shall affect the right of EMPLOYEE or XM thereafter to
enforce each and every provision of this Agreement in accordance with its terms.

         7.9. ADDITIONAL OBLIGATIONS. Both during and after the term of
employment, EMPLOYEE shall, upon reasonable notice, furnish XM with such
information as may be in EMPLOYEE's possession or control, and cooperate with
XM, as may reasonably be requested by XM (and, after the term of employment,
with due consideration for EMPLOYEE's obligations with respect to any new
employment or business activity) in connection with any litigation or other
adversarial proceedings in which XM or any Affiliate is or may become a party.
XM shall reimburse EMPLOYEE for all reasonable expenses incurred by EMPLOYEE in
fulfilling EMPLOYEE's obligations under this Article 7.9.

         IN WITNESS WHEREOF, the parties have executed this Agreement to be
effective as of the Effective Date.
