of the OC Obligations or with respect to this Agreement; or the receipt,
exchange, surrender or acquiescence in, any default with respect to any of the

     3.   INDEMNIFICATION.

          3.1  GENERALLY. Without limitation of any other obligations of Propel
or remedies of Motorola under this Agreement, Propel shall, to the fullest
extent permitted by law, indemnify, defend, save and hold harmless Motorola and
each of its Affiliates and their respective officers, directors, employees,
agents and advisors (each, an "INDEMNIFIED PARTY") from and against, and shall
pay on demand, any and all claims, damages, losses, liabilities and expenses
(including, without limitation, reasonable fees and expenses of counsel) that
may be incurred by or asserted or awarded against any Indemnified Party in

Party in connection with the Motorola Commitments; PROVIDED that Propel shall

losses, liabilities, and expenses to the extent (but only to the extent)
resulting from such Indemnified Party's gross negligence or willful misconduct,
as determined by a court of competent jurisdiction or an arbitrator or mediator
pursuant to Sections 13.7, 13.8 and 13.9 herein.

          3.2  NO PUNITIVE DAMAGES. The Parties hereby also agrees that none of
the Indemnified Parties shall have any liability (whether direct or indirect, in
contract, tort or otherwise) to either Party or any of its Affiliates or any of
their respective officers, directors, employees, agents and advisors, and both
Parties hereby agree not to assert any claim against any Indemnified Party on
any theory of liability, for special, indirect, consequential or punitive
damages arising out of or otherwise relating to the Motorola Commitments or any
of the transactions contemplated by the Motorola Commitments.

          3.3  SURVIVAL. Without prejudice to the survival of any of the other
agreements under this Agreement or any of the other agreements under the
Motorola Commitments, the agreements and obligations of Propel contained in
Section 2.1 (solely with respect to enforcement expenses) and this Section 3,
and the obligations of Motorola contained in Section 7 shall survive the payment
in full of the Guaranteed Obligations and all of the other amounts payable under
this Agreement.

     4.   PAYMENTS FREE AND CLEAR OF TAXES, ETC. Any payment, indemnification or
reimbursement made by Propel hereunder shall be free and clear of all Taxes,
charges, fees, costs, expenses, or duties imposed by any Governmental Authority
and if any such Governmental Authority requires the payment and/or withholding
of any of the foregoing, Propel shall be liable for all of such Taxes, charges,
costs, expenses or duties.

against each Party in accordance with its terms, except as limited by
bankruptcy, insolvency or other laws of general application relating to or
affecting the enforcement of creditors' rights generally;

          5.2  the execution, delivery and performance of this Agreement do not
(i) violate any provisions of law or any order of any court or other agency of

performance of either Party's obligations hereunder have been obtained, and each

rights exercised by Propel against the Operating Companies with respect to
payments made by Propel hereunder. Any payments on such indebtedness to Propel,
if Motorola so requests, shall be collected, enforced and received by Propel, in

liability of Propel under the other provisions of this Agreement. Motorola is
authorized and empowered, but not obligated, in its discretion, to require
Propel (i) to collect and enforce, and to submit claims in respect of, any
indebtedness of the Operating Companies to Propel, and (ii) to pay any amounts
received on such indebtedness to Motorola for application to the Guaranteed
Obligations.

          9.2  UPON DEFAULT BY PROPEL. Without limiting the generality of
Section 9.1 above, upon the occurrence and during the continuance of any default
by Propel hereunder not cured to Motorola's reasonable satisfaction within five
(5) days of the delivery by Motorola to Propel of written notice of such
default, Propel agrees that Motorola shall be entitled to receive payment from
Propel, Inc. of all Guaranteed Obligations then due and payable prior to
Propel's receipt of payment of any amount of any indebtedness of the Operating
Companies to Propel, including without limitation, any dividends, distributions
or repayments of shareholder loans. Any payments on such indebtedness to Propel,
if Motorola so requests, shall be collected, enforced and received by Propel, in
trust, as trustee for Motorola and shall be paid over to Motorola on account of
the Guaranteed Obligations, but without reducing or affecting in any manner the
liability of Propel under the other provisions of this Agreement. Motorola is
authorized and empowered, but not obligated, in its discretion, to require
Propel (i) to collect and enforce, and to submit claims in respect of, any
indebtedness of each of the Operating Companies to Propel, and (ii) to pay any
amounts received on such indebtedness to Motorola for application to the
Guaranteed Obligations of the Operating Company from which Propel received
payment. Upon the occurrence and during the continuance of any default by Propel
hereunder not cured to Motorola's reasonable satisfaction within five (5) days
of the delivery by Motorola to Propel of written notice of such default,
Motorola is authorized and empowered, but not obligated, in its discretion in
the name of Propel, to


                                       11
<PAGE>

collect and enforce, and to submit claims in respect of, any indebtedness of
each of the Operating Companies to Propel and to apply any amounts received
thereon to the Guaranteed Obligations of the Operating Company from which Propel
received payment.

     10.  SUBROGATION. Absent the written consent of Motorola, which shall not
be unreasonably withheld, Propel shall not exercise any rights which it may
acquire by way of subrogation under this Agreement with respect to a particular
Operating Company, by any payment hereunder or otherwise, until all of the
Guaranteed Obligations with respect to such Operating Company have been
irrevocably paid in full, in cash, and Motorola shall have no further
obligations to such Operating Company under the applicable Motorola Commitments.
If any amount shall be paid to Propel on account of such subrogation rights at
any other time, such amount shall be held in trust for the benefit of Motorola
and shall be forthwith paid to Motorola to be credited and applied to the
Guaranteed Obligations of the particular Operating Company making such payment,
whether matured or unmatured, in such manner as Motorola shall determine in its
sole discretion on a reasonable basis.

     11.  ASSIGNMENT OF MOTOROLA'S RIGHTS. Motorola may, from time to time, with
notice to Propel, assign or transfer any or all of the Guaranteed Obligations or
any interest therein and, notwithstanding any such assignment or transfer of the
Guaranteed Obligations or any subsequent assignment or transfer thereof, the
Guaranteed Obligations shall be and remain the Guaranteed Obligations for the
purpose of this Agreement. Each and every immediate and successive assignee or
transferee of any of the Guaranteed Obligations or of any interest therein
shall, to the extent of such party's interest in the Guaranteed Obligations, be
entitled to the benefits of this Agreement to the same extent as if such
assignee or transferee were Motorola; provided, however, that unless Motorola
shall otherwise consent in writing, Motorola shall have an unimpaired right,
prior and superior to that of any such assignee or transferee, to enforce this
Agreement for its own benefit as to those of the Guaranteed Obligations which
Motorola has not assigned or transferred.

     12.  FINANCIAL CONDITION OF THE OPERATING COMPANIES.

          12.1 NO RELIANCE ON MOTOROLA. Propel represents and warrants that it
is fully aware of the financial condition of the Operating Companies, and Propel
delivers this Agreement based solely upon Propel's own independent investigation
of the Operating Companies' financial condition and in no part upon any
representation or statement of Motorola with respect thereto. Propel further
represents and warrants that it is in a position to and hereby does assume full
responsibility for obtaining such additional information concerning the
Operating Companies' financial condition as Propel may deem material to its
obligations hereunder, and Propel is not relying upon, nor expecting Motorola to
furnish it any information in Motorola's possession concerning the Operating
Companies' financial condition or concerning any circumstances bearing on the
existence or creation, or the risk of nonpayment or nonperformance of the
Guaranteed Obligations.


                                       12
<PAGE>

          12.2 WAIVER. Propel hereby waives any duty on the part of Motorola to
disclose to Propel any facts it may now or hereafter know about the Operating
Companies, regardless of whether Motorola has reason to believe that any such
facts materially increase the risk beyond that which Propel intends to assume or
has reason to believe that such facts are unknown to Propel.

          12.3 ACKNOWLEDGEMENT. Propel hereby knowingly accepts the risk
encompassed within this Agreement which includes, without limitation, the
possibility that the Operating Companies will contract for additional
indebtedness for which Propel may be liable hereunder after the Operating
Companies' financial condition or ability to pay its lawful debts when they fall
due has deteriorated.

<PAGE>

          13.7. JURISDICTION. In the event a Dispute under this Agreement is to
be submitted to judicial proceedings, each of Motorola and Propel consents to
the exclusive jurisdiction of the federal or state courts of Illinois for any
such legal action, suit or proceeding and agrees that any such action, suit, or
proceeding may be brought only in such courts. Each of Motorola and Propel
further waives any objection to the laying of venue for any suit, action or
proceeding in such courts. Each party agrees to accept and acknowledge service
of any and all process that may be served in any suit, action or proceeding.
Each party agrees that any service of process upon it mailed by registered or
certified mail, return receipt requested to such party at the address provided
in Section 16.3 above will be deemed in every respect effective service of
process upon such party in any such suit, action or proceeding. EACH PARTY
AGREES TO WAIVE ANY RIGHT IT MIGHT HAVE TO A TRIAL BY JURY IN ANY SUCH SUIT,
ACTION OR PROCEEDING.


          13.8. AMICABLE RESOLUTION. (a) Motorola and Propel mutually desire
that friendly collaboration will develop between them. Accordingly, they will
try to resolve in an amicable manner all disagreements and misunderstandings
connected with their respective rights and obligations under this Agreement,
including any amendments hereto. In furtherance thereof, in the event of any
dispute or disagreement between Motorola and Propel as to the interpretation of
any provision of this Agreement executed in connection herewith (or the
performance of obligations hereunder or thereunder), the matter, upon written
request of either party, will be referred for resolution to a steering committee
established pursuant to Section 5.7 of the Master Separation Agreement (the
"STEERING COMMITTEE"). The Steering Committee will have two members, one of
which will be appointed by Motorola and one of which will be appointed by
Propel. The initial members of the Steering Committee will be the individuals
named on Schedule 5.7 of the Master Separation Agreement. Each of Motorola and
Propel will use its good faith reasonable efforts to avoid replacing the initial
members of the Steering Committee with another of their representatives for the
first year after the Effective Date. Thereafter, Motorola and Propel will, to
the extent practicable, honor the other's reasonable objections to any
replacements of Steering Committee members. While any person is serving as a
member of the Steering Committee, such person may not designate any substitute
or proxy for purposes of attending or voting at a Steering Committee meeting.
The Steering Committee will make every good faith effort to promptly resolve all
disputes or disagreements referred to it. Upon a unanimous vote, Steering
Committee decisions will be binding on Motorola and on Propel. If the Steering
Committee does not agree to a resolution of the dispute or disagreement within
90 days after the reference of the matter to it, each of Motorola and Propel
will be free to exercise the remedies available to it under applicable law,
subject to Section 13.9. Notwithstanding anything to the contrary in this
Section 13.8, no amendment to the terms of this Agreement will be effected
except in writing signed by an authorized officer of both parties. The Steering
Committee will be self-regulating.

     (b)  Between the Effective Date and the first anniversary of the Effective
Date the Steering Committee will hold meetings every six weeks on dates
established at the


                                       15
<PAGE>

organizational meeting of the Steering Committee, which will be held as promptly
as practicable after the Effective Date. Such meeting dates may be rescheduled
by the Steering Committee if it becomes reasonably impracticable to hold such a
meeting. After the first anniversary of the Effective Date, the Steering
Committee will hold regularly scheduled meetings as determined by the Steering
Committee.

     13.9 MEDIATION AND ALTERNATE DISPUTE RESOLUTION. (a) To the extent that any
misunderstanding or dispute with respect to one or more of the terms of this
Agreement ("DISPUTE") cannot be resolved in a friendly manner as set forth in
Section 13.8, the parties intend that such Dispute be resolved by an alternative
dispute resolution process ("ADR"), which shall require the escalation of any
Dispute, first, to the level of one senior executive of each of Motorola and
Propel (the "Senior Officers") and then to the head of Motorola's Communications
Enterprise (or its successor) and the CEO of Propel in an attempt to resolve any
such Dispute by negotiation. If the Senior Officers and/or the head of Motorola'
s Communications Enterprise and the Propel CEO are unable to resolve the Dispute
within ten days after the matter is referred to them, either Motorola or Propel
may demand mediation of the Dispute by written notice to the other. The two
parties shall select a mediator within ten days after the demand and neither of
the parties may unreasonably withhold consent to the selection of the mediator
and both parties shall share the cost of mediation equally. The parties may
agree to replace mediation with some other form of non-binding ADR such as
neutral fact finding or mini-trial. Nothing in this paragraph shall prevent
either Motorola or Propel from commencing formal litigation proceedings if (i)
good faith efforts to resolve the Dispute under these procedures have been
unsuccessful, or (ii) any delay resulting from efforts to mediate such dispute
could result in serious and irreparable injury to either Motorola or Propel. The
use of any ADR procedures will not be construed under the doctrines of laches,
waiver or estoppel to affect adversely the rights of either party.

     (b)  Each of Motorola and Propel will bear its costs of mediation or ADR,
but both parties shall share the costs of the mediation or ADR equally.

          13.10. SEVERABILITY. If any term or other provision of this Agreement
is invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that transactions contemplated hereby are fulfilled to the fullest extent
possible.

          13.11. FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No
failure or delay on the part of any party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude other or
further exercise thereof or of any other right. All rights


                                       16
<PAGE>

and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          13.12. AMENDMENT. No change, amendment or waiver will be made to this
Agreement except by an instrument in writing signed on behalf of each of the
parties to such agreement.

          13.13. INTERPRETATION. All references herein to Operating Companies
shall be deemed to include their successors and assigns, and all references
herein to Propel shall be deemed to include Propel and Propel's successors and
assigns. The headings contained in this Agreement, in any Exhibit or Schedule
hereto and in the table or contents to this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement. Any capitalized term used in any Schedule or Exhibit but not
otherwise defined therein, shall have the meaning assigned to such term in this
Agreement. When a reference is made in this Agreement to an Article or a
Section, Exhibit or Schedule, such reference shall be to an Article or Section
of, or an Exhibit or Schedule to, this Agreement unless otherwise indicated. The
Schedules and Exhibits attached hereto or referred to herein are an integral
part of this Agreement and are hereby incorporated into this Agreement and made
a part hereof as if set forth in full herein. After the Effective Date, the
Propel Business shall be deemed to be the business of Propel and its
Subsidiaries.

          13.14 NO CROSS-COLLATERALIZATION. Notwithstanding anything set forth
in this Agreement to the contrary, nothing contained herein shall result in any
Operating Company being liable, directly or indirectly, for the obligations or
liabilities of any other Operating Company or of Propel.

          13.15. ADVICE OF COUNSEL. Propel acknowledges that Propel has either
obtained the advice of counsel or has had the opportunity to obtain such advice
in connection with the terms and provisions of this Agreement.

          13.16. PROPEL'S RIGHT TO ASSERT A CLAIM FOR BREACH OF THIS AGREEMENT.
Notwithstanding anything contained herein to the contrary, Propel shall have the
right to assert claims in good faith based upon material breaches by Motorola of
this Agreement in a court of competent jurisdiction pursuant to Section 13.7
herein or before an arbitrator pursuant to Section 13.8. Notwithstanding the
foregoing right of Propel, any alleged or actual breach by Motorola hereunder
shall in no manner and under no circumstances create any claim, defense, right
of set-off or any other right (except for counterclaims resulting from any
separate proceeding brought by Propel pursuant to this Section 13.16) for Propel
with respect to its payment and performance obligations under this Agreement,
and such obligations of Propel shall be unconditional, absolute and continuing
as set forth in Sections 2.1 and 2.2 herein.

          13.17. TERM. Without limiting the generality of any other provision of
this Agreement, including Section 3.3 hereof, this Agreement shall be effective
upon the


                                       17
<PAGE>

Effective Date and the obligations of Propel shall continue until the
Beneficiaries each acknowledge in writing that the Guaranteed Obligations have
been fully and properly paid, released or terminated.


                            [signature pages follow]
