Licenses except for the CPAN Lien, or (ii) violate or conflict with, result in a
breach of the terms, conditions or provisions of, or constitute a default, an
event of default or an event creating rights of acceleration, termination,

to, authorization or approval of, filing with or consent under: (1) any material
note, indenture, instrument, agreement, mortgage, lease, License, franchise,

constitutes or, after notice or lapse of time or both, would constitute a breach

Licenses, or of any event, condition or state of facts described in the
preceding clause, has been received by, or is known to, Sellers. The Licenses
are valid, subsisting and in full force and effect and may be assigned and
transferred to Buyer in accordance with this Agreement and will continue in full
force and effect thereafter, in each case without (1) the occurrence of any
breach, default or forfeiture of rights thereunder, or (2) except for the FCC
Consent and HSR Approval, the consent, approval, or act of, or the making of any
filing with, any Governmental Body. Sellers have no reason to believe that the
Licenses are not likely to be renewed in the ordinary course or that the holder
of such Licenses, if qualified, would not be entitled to renewal expectancy as
contemplated by FCC rules and regulations. The Licenses (i) were granted on the
grant date specified on Exhibit A, (ii) expire on the expiration dates specified
on Exhibit A, and (iii) are subject to the five-year construction milestone
dates occurring on the date specified on Exhibit A.

               4.5 Title to Licenses. Sellers have good and marketable title to
the Licenses, free and clear of all Encumbrances. Upon delivery to Buyer on the

proceeding pending or, to the best knowledge of Sellers and the Shareholder,
threatened against any of the Sellers, relating to any of the Sellers or the
Licenses which, if adversely determined, either would result in the revocation,
cancellation, suspension or adverse modification of the Licenses or would have a
material adverse effect on the ability of Sellers to perform their obligations
hereunder or upon the financial condition, assets, business, prospects or
results of operations of any of the Sellers, nor are any of the Sellers aware of
any reasonable basis for any such investigation, claim, action, suit or
proceeding.

               4.7 No Finder. No broker or finder has acted on behalf of Sellers
or the Shareholder in connection with the transactions contemplated hereby.

               4.8 FCC Matters.

               (a) The Licenses listed as "MVI Licenses" on Exhibit A are
validly issued in the name of MVI. The Licenses listed as "CPAN Licenses" on
Exhibit A are validly issued in the name of CPAN. The Licenses listed as "RSA
Licenses" on Exhibit A are validly issued in the name of RSA. Sellers applied
for and obtained the Licenses in compliance with FCC law, and Sellers are, and
on the Closing Date will be, the exclusive holders of the Licenses. The Licenses
have been granted by Final Order. The Licenses are in full force and effect, are
unimpaired by any acts or omissions of the Sellers or their affiliates, and are
free and clear of any restrictions which might limit the full operation of the
Licenses, other than such restrictions as are imposed on PCS licenses and/or the
wireless telecommunications industry generally. All reports and other documents
required to be filed by Sellers and their affiliates with the FCC and with state
regulatory authorities with respect to the Licenses have been filed. All such
reports and documents are correct in all material respects.

               (b) Neither the Sellers nor the Shareholder have engaged in any
course of conduct which would impair Sellers' ability to remain holders of FCC
licenses, and Sellers and the Shareholder are not aware of any reason why the
Licenses might be revoked, canceled, suspended or otherwise transferred as a
result of the transactions contemplated hereby. All material payments and fees
of Sellers due and payable at or prior to the Closing Date to Governmental
Bodies pursuant to the Licenses have been paid. Subject to obtaining the consent
of the FCC to assign the Licenses to Buyer, Sellers have, and on the Closing
Date will have, the absolute and unrestricted right, power and authority under
FCC law to hold the Licenses.

               (c) Sellers are in compliance with Section 310(b) of the
Communications Act, and all rules, regulations or policies of the FCC
promulgated thereunder with respect to alien ownership.

               5.5 Qualification. Buyer is legally qualified to be an FCC
licensee generally and specifically with regard to the Licenses, and to Buyer's
knowledge, to receive any authorization or approval from any state or local
regulatory authority necessary for it to acquire the Licenses. Buyer is in
compliance with Section 310(b) of the Communications Act, and all rules,
regulations or policies of the FCC promulgated thereunder with respect to alien
ownership.

actions between the date hereof and the Closing Date:

<PAGE>   10

               6.1 Investigation by Buyer. Sellers shall provide Buyer a copy of
the Licenses and shall furnish to Buyer or its authorized representatives such
additional information concerning the Licenses and Sellers as shall be
reasonably requested, including all such information as shall be necessary to
enable Buyer or its representatives to verify the accuracy of the
representations and warranties contained in this Agreement, to verify that the
covenants of Sellers contained in this Agreement have been complied with and to
determine whether the conditions set forth in Article VIII have been satisfied.
No investigation made by Buyer or its representatives hereunder shall affect the
representations and warranties of the Sellers or the Shareholder hereunder;
provided, however, Buyer shall promptly notify Sellers and the Shareholder to
the extent it discovers any fact or circumstance that indicates that any Seller
or the Shareholder has breached a representation or warranty hereunder.

               6.2 Preserve Accuracy of Representations and Warranties. Each of
the parties hereto shall refrain from taking any action that would render any
representation or warranty contained in this Agreement inaccurate in any
material respect as of the Closing Date. Each party shall promptly notify the
other in writing (a) of any action, suit or proceeding that shall be instituted
or threatened against such party to restrain, prohibit or otherwise challenge
the legality of any transaction contemplated by this Agreement, (b) of any
development causing a breach of any of the representations and warranties of
such party in Articles IV or V above, as applicable, or (c) of any lawsuit,
claim, proceeding or investigation that may be threatened, brought, asserted or
commenced against such party which would have been disclosed if such lawsuit,
claim, proceeding or investigation had arisen prior to the date hereof. No
disclosure by any party pursuant to this Section 6.2, however, shall be deemed
to amend or supplement this Agreement or to prevent or cure any
misrepresentation, breach of warranty or breach of covenant therein.

               6.3 Consents of Third Parties; Governmental Approvals.

               (a) Consents. Sellers will act diligently and reasonably to
secure, before the Closing Date, any consent, approval or waiver, in form and
substance reasonably satisfactory to Buyer, from any party as required to be
obtained to assign or transfer the Licenses to Buyer or to otherwise satisfy the
conditions set forth herein; provided that none of the Sellers nor Buyer shall
have any obligation to offer or pay any consideration in order to obtain any
such consent or approval; and provided, further, that Sellers shall not make any
agreement or understanding affecting the Licenses as a condition for obtaining
any such consent, approval or waiver except with the prior written consent of
Buyer. During the period prior to the Closing Date, Buyer shall act diligently
and reasonably to cooperate with Sellers to obtain the consents, approvals and
waivers contemplated by this Section 6.3(a).

               (b) FCC Consents. Sellers and Buyer shall, as promptly as
practicable following the date of this Agreement and in any event within thirty
(30) days after the date of this Agreement, file with the FCC an FCC Form 603
(or other appropriate form) application seeking consent to assign the Licenses
from Sellers to Buyer or Buyer's subsidiary. The parties shall cooperate and use
their respective reasonable efforts to prosecute such application to a favorable
conclusion and shall share equally any filing fees.

               (c) HSR Filing. As soon as reasonably practicable following the
execution and delivery of this Agreement and in any event within thirty (30)
days after the date of this

Agreement, Sellers, the Shareholder and Buyer will take such action, if any, as
may be required to be taken by them under the HSR Act in connection with the
transactions contemplated hereby. Each party will cooperate in the preparation
of, and will file complete and accurate notification and report forms with
respect to the transactions contemplated hereby, pursuant to the HSR Act and the
rules and regulations promulgated thereunder, and will file on a timely basis
such additional information and documentary materials as may be requested by any
Governmental Body pursuant to the HSR Act. Each party will request early
termination of the waiting period under the HSR Act. Each party shall promptly
inform the other of any inquiries or communications from any such Governmental
Body and provide copies of any written communication relating thereto. Each
party shall respond with reasonable diligence and dispatch to any request for
additional information made in response to such filings. Each party shall pay
its respective costs of compliance with the HSR Act; it being understood that
Buyer will pay the applicable application fee.

               6.4 Operations Prior to the Closing Date. At all times prior to
the Closing, Sellers shall keep and maintain the Licenses current and in good
standing, including without limitation, making any payment of principal, accrued
interest, penalties or other indebtedness (if any) due to the FCC with respect
to the Licenses on a timely basis. Sellers shall retain control of the Licenses

                      (i) Sell, lease, transfer or otherwise dispose of, or
mortgage or pledge, or impose or suffer to be imposed any Encumbrance on, the
Licenses; or

                      (ii) Take or agree to take any other action inconsistent
with the consummation of the transactions contemplated by this Agreement.

               6.5 Exclusivity. Until the termination of this Agreement, Sellers
and the Shareholder will not (and Sellers and the Shareholder will cause their
respective affiliates not to) (a) solicit, initiate, or encourage the submission
of any proposal or offer from any Person relating to the acquisition of the
Licenses or (b) participate in any discussions or negotiations regarding,
furnish any information with respect to, assist or participate in, or facilitate
in any other manner any effort or attempt by any Person to do or seek any of the
foregoing. Sellers will notify Buyer immediately if any Person makes any
proposal, offer, inquiry, or contact with respect to any of the foregoing, which
notice shall include the identity of the Person making the proposal, offer,
inquiry or contact, and a summary of the principal terms thereof. Likewise,
Buyer (and each of its directors, officers, employees and agents) shall not (x)
solicit, initiate, or encourage the submission of any proposal or offer from any
Person relating to the acquisition of any PCS Licenses in the BTAs which would
be purchased by Buyer in lieu of the Licenses, or (y) participate in any
discussions or negotiations regarding, furnish any information with respect to,
assist or participate in, or facilitate in any other manner any effort or
attempt by any Person to do or seek any of the foregoing. Buyer will notify
Sellers immediately if any Person makes any proposal, offer, inquiry, or contact
with respect to any of the foregoing, which notice shall include the identity of
the Person making the proposal, offer, inquiry or contact, and a summary of the
principal terms thereof.

would cause any Governmental Body to institute proceedings for the suspension,
revocation, or material and adverse modification of any of such governmental
authorizations or fail to prosecute with due diligence any pending applications
for any Governmental Body in connection with the Licenses.

               7.3 Radio Frequency Testing Letter. Simultaneously with the

Licenses in accordance with applicable Requirements of Law and the rules,
regulations and written policies and orders of the FCC. Without limiting the
foregoing, except for FCC build-out requirements generally applicable to the
Licenses, Buyer shall have no obligation to provide wireless telecommunications
services under the Licenses to any of Sellers' current or future customers, nor
to provide for the transition of Sellers' current or future customers to

               10.1 Survival. All of the representations and warranties of the
parties contained in Article IV or Article V shall survive the Closing hereunder

breach of warranty at the time of such Closing, unless the other party expressly
waives in writing any such breach at or before the time of such Closing) and
shall continue in full force and effect until the two (2) year anniversary of

force and effect forever thereafter.

               10.2 Indemnification by MVI, CPAN and the Shareholder. In the
event MVI, CPAN or the Shareholder breaches (or in the event any third party
alleges facts that, if true, would mean MVI, CPAN or the Shareholder has
breached) any of its representations, warranties, or covenants contained herein
and, if there is an applicable survival period pursuant to Section 10.1 above
and the Buyer makes a written claim against MVI, CPAN or the Shareholder within
such period, or in the event of any actual or threatened claim, action, suit or
proceeding against Buyer or any of its subsidiaries arising from MVI's or CPAN's
ownership or operation of the Licenses listed as "MVI Licenses" or "CPAN
Licenses" on Exhibit A hereto prior to the Closing or arising from or relating
to the transitioning of existing customers off the spectrum represented by the
Licenses listed as "MVI Licenses" or "CPAN Licenses" on Exhibit A pursuant to

                                       14
<PAGE>   15

to Section 10.1 above and the Buyer makes a written claim against RSA within
such period, or in the event of any actual or threatened claim, action, suit or
proceeding against Buyer or any of its subsidiaries arising from RSA's ownership
or operation of the Licenses listed as "RSA Licenses" on Exhibit A hereto prior
to the Closing or arising from or relating to the transitioning of all existing
customers off the spectrum represented by the Licenses listed "RSA Licenses" on
Exhibit A pursuant to Section 7.4 hereof, then RSA and the Shareholder jointly
and severally agree to indemnify the Buyer and its directors, officers,

               10.6 Notice of Claims.

               (a) Any party (the "Indemnified Party") seeking indemnification
under this Article X shall give to the party obligated to provide
indemnification to such Indemnified Party (the "Indemnitor") a notice (a "Claim
Notice") describing in reasonable detail the facts giving rise to any claim for
indemnification hereunder and shall include in such Claim Notice (if then known)
the amount or the method of computation of the amount of such claim, and a
reference to the provision of this Agreement or any agreement, document or
instrument executed pursuant hereto or in connection herewith upon which such
claim is based; provided, that a Claim Notice

                                       15
<PAGE>   16

shall be given promptly after the Indemnified Party knows or reasonably should
have known of the circumstances giving rise to the claim; provided further that
failure to give such notice shall not relieve the Indemnitor of its obligations
hereunder except to the extent it shall have been prejudiced by such failure.

               (b) Subject to Section 10.5, after the giving of any Claim Notice
pursuant hereto, the amount of indemnification to which an Indemnified Party
shall be entitled under this Article X shall be determined: (i) by the written
agreement between the Indemnified Party and the Indemnitor; or (ii) an award
from an arbitrator pursuant to Section 12.11 hereof or by a final judgment or
decree of any court of competent jurisdiction. The judgment or decree of a court
shall be deemed final when the time for appeal, if any, shall have expired and
no appeal shall have been taken or when all appeals taken shall have been
finally determined. The Indemnified Party shall have the burden of proof in
establishing the amount of Losses and Expenses suffered by it.

               10.7 Third Person Claims.

               (a) Subject to Section 10.7(b), the Indemnified Party shall have
the right to conduct and control, through counsel of its choosing, the defense,
compromise or settlement of any third Person claim, action or suit against such
Indemnified Party as to which indemnification will be sought by any Indemnified
Party from any Indemnitor hereunder, and in any such case the Indemnitor shall
cooperate in connection therewith and shall furnish such records, information
and testimony and attend such conferences, discovery proceedings, hearings,
trials and appeals as may be reasonably requested by the Indemnified Party in
connection therewith; provided, that the Indemnitor may participate, through
counsel chosen by it and at its own expense, in the defense of any such claim,
action or suit as to which the Indemnified Party has so elected to conduct and
control the defense thereof; and provided, further, that the Indemnified Party
shall not, without the written consent of the Indemnitor (which written consent
shall not be unreasonably withheld), pay, compromise or settle any such claim,
action or suit, except that no such consent shall be required if, following a
written request from the Indemnified Party, the Indemnitor shall fail, within
fourteen (14) days after the making of such request, to acknowledge and agree in
writing that, if such claim, action or suit shall be adversely determined, such
Indemnitor has an obligation to provide indemnification hereunder to such
Indemnified Party. Notwithstanding the foregoing, the Indemnified Party shall
have the right to pay, settle or compromise any such claim, action or suit
without such consent, provided that in such event the Indemnified Party shall
waive any right to indemnity therefor hereunder unless such consent is
unreasonably withheld.

               (b) If any third Person claim, action or suit against any
Indemnified Party is solely for money damages (and, where a Seller or the
Shareholder is the Indemnitor, such claim, action or suit will have no
continuing effect in any material respect on the Licenses), then the Indemnitor
shall have the right to conduct and control, through counsel of its choosing,
the defense, compromise or settlement of any such third Person claim, action or
suit against such Indemnified Party as to which indemnification will be sought
by any Indemnified Party from any Indemnitor hereunder if the Indemnitor has
acknowledged and agreed in writing that, if the same is adversely determined,
the Indemnitor has an obligation to provide indemnification to the Indemnified
Party in respect thereof, and in any such case the Indemnified Party shall
cooperate

                                       16
<PAGE>   17

in connection therewith and shall furnish such records, information and
testimony and attend such conferences, discovery proceedings, hearings, trials
and appeals as may be reasonably requested by the Indemnitor in connection
therewith; provided, that the Indemnified Party may participate, through counsel
chosen by it and at its own expense, in the defense of any such claim, action or
suit as to which the Indemnitor has so elected to conduct and control the
defense thereof. Notwithstanding the foregoing, the Indemnified Party shall have
the right to pay, settle or compromise any such claim, action or suit, provided
that in such event the Indemnified Party shall waive any right to indemnity
therefor hereunder unless the Indemnified Party shall have sought the consent of
the Indemnitor to such payment, settlement or compromise and such consent was
unreasonably withheld, in which event no claim for indemnity therefor hereunder
shall be waived.

               10.8 Amount of Indemnification Payments. In calculating any Loss
or Expense there shall be deducted any insurance recovery in respect thereof
(and no right of subrogation shall accrue hereunder to any insurer).

                                   ARTICLE XI.
                                   TERMINATION

               11.1 Termination. Anything contained in this Agreement to the
contrary notwithstanding, this Agreement may be terminated:

               (a) By the mutual written consent of Sellers and Buyer;

               (b) By either Buyer on the one hand, or Sellers and the
Shareholder on the other hand, upon written notice to the other, in the event
the other party (the "Breaching Party") has materially breached its
representations, warranties or covenants contained in this Agreement and failed
to cure such breach within the 30-day cure period specified in this subsection;
provided, however, that the party claiming such breach (i) is not itself in
material breach of its representations, warranties or covenants contained
herein, (ii) promptly notifies the Breaching Party in writing (the "Termination
Notice") of its intention to exercise its rights under this Agreement as a
result of the breach, and (iii) specifies in such Termination Notice the
representation, warranty or covenant of which the Breaching Party is allegedly
in material breach;

               (c) By either Buyer on the one hand, or Sellers on the other
hand, upon written notice to the other, upon the filing by any of the Sellers or
the Shareholder or by Buyer, as the case may be, or having filed against it and
remaining pending for more than thirty (30) days, a petition under Title 11 of
the United States Code or similar state law provision seeking protection from
creditors or the appointment of a trustee, receiver or debtor in possession;

               (d) By either Buyer on the one hand, or Sellers on the other
hand, upon written notice to the other, if a court of competent jurisdiction
shall have issued an order, decree or ruling permanently restraining, enjoining
or otherwise prohibiting any of the transactions contemplated by this Agreement,
and such order, decree, ruling or other action shall have become final and
non-appealable;

                                       17
<PAGE>   18

               (e) By either Buyer on the one hand, or Sellers on the other
hand, upon twenty (20) days' prior written notice of such termination, if the
Closing shall not have occurred on or before the one (1) year anniversary of the
Effective Date of this Agreement; or

               (f) By Sellers upon twenty (20) days prior written notice of such
termination, if any of the lenders under the Vendor Financing Agreements shall
have accelerated any of the indebtedness thereunder following a default by Buyer
thereunder.

               11.2 Effect of Termination. In the event of termination of this
Agreement by either party, except as otherwise provided herein, all rights and
obligations of the parties under this Agreement shall terminate without any
liability of any party to any other party (except for any liability of any party
then in breach of its covenants hereunder). The provisions of Sections 11.2,
12.1, 12.6, 12.7, 12.8, 12.11, 12.12, and 12.13 shall expressly survive the
expiration or termination of this Agreement. Nothing is this Section 11.2 shall
be deemed to release any party from any liability for breach by such party of
its obligations under this Agreement or from any obligations that exist under
separate agreements between the parties.

               (a) The rights of any party under this Agreement shall not be
assignable by such party hereto prior to the Closing without the written consent
of the other, except that the rights (but not obligations) of Buyer hereunder

Shareholder, to any of its affiliates, subsidiaries and successors ("Permitted
Assignees").

               (b) This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their successors and permitted assigns. The successors
and permitted assigns hereunder shall include without limitation, in the case of
Buyer, any Permitted Assignees as well as the successors in interest to such

reason of this Agreement.

               12.5 Entire Agreement; Amendments. This Agreement and the
Exhibits referred to herein and the documents delivered pursuant hereto contain
the entire understanding of the parties hereto with regard to the subject matter
contained herein or therein, and supersede all prior agreements, understandings

and the Shareholder, on the other hand.

               12.6 Waivers. Any failure of Buyer on the one hand, or Sellers or
the Shareholder, on the other hand, to comply with any obligation, covenant,
agreement or condition herein may be waived by the other party only by a written
instrument signed by Buyer or Sellers, as applicable, granting such waiver, but
such waiver or failure to insist upon strict compliance with such obligation,
covenant, agreement or condition shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure.

               12.7 Expenses. Each party hereto will pay all of its own costs
and expenses incident to its negotiation and preparation of this Agreement and
the consummation of the transactions contemplated hereby, including the fees,
expenses and disbursements of its counsel and advisors. In the event any party
shall bring an action or arbitration in connection with the performance, breach
or interpretation of this Agreement, the prevailing party in any such action or
arbitration shall be entitled to recover from the losing party all reasonable
costs and expenses of such action or arbitration, including attorneys' fees.

               12.8 Partial Invalidity. Wherever possible, each provision hereof
shall be interpreted in such manner as to be effective and valid under
applicable law, but in case any one or more of the provisions contained herein
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, such provision shall be ineffective to the extent, but only to the
extent, of such invalidity, illegality or unenforceability without invalidating
the remainder of such provision or provisions or any other provisions hereof,
unless such a construction would be unreasonable; provided, however, that if the
removal of such offending term or provision materially alters the burdens or
benefits of any of the parties under this Agreement, the parties agree to
negotiate in good faith such modifications to this Agreement as are appropriate
to ensure the burdens and benefits of each party under such modified Agreement
are reasonably comparable to the burdens and benefits originally contemplated
and expected.

               12.9 Execution in Counterparts. This Agreement may be executed in
one or more counterparts which may be delivered by facsimile, each of which
shall be considered an original instrument, but all of which shall be considered
one and the same agreement, and shall become binding when one or more
counterparts have been signed by each of the parties hereto and delivered to
each of the other parties hereto.

               12.10 Further Assurances. From time to time following the
Closing, Sellers and the Shareholder shall execute and deliver, or cause to be
executed and delivered, to Buyer such other instruments of conveyance and
transfer as Buyer may reasonably request or as may be otherwise necessary to
more effectively convey and transfer to, and vest in, Buyer and put the Buyer in
possession of the Licenses.

               12.11 Resolution of Disputes. Except with respect to a breach of
the obligations of confidentiality set forth in Section 12.1 and actions
detrimental to the acquisition of the Licenses contemplated hereunder, as to
which the non-breaching party shall have the right to seek specific performance,
injunctive remedy or other equitable remedies, senior management employees of
Buyer and Sellers shall meet and negotiate in good faith to reach a satisfactory
resolution to any dispute arising in connection with this Agreement. If such
negotiations do not result in a resolution within five (5) days after the first
meeting of such representatives, then any dispute, claim or controversy arising
under this Agreement or in any way related to this Agreement, or its
interpretation, enforceability or inapplicability may be submitted to binding
arbitration at the election of either Buyer or Sellers. The arbitration shall be
conducted by a single arbitrator. The arbitration shall be conducted in Denver,
Colorado in accordance with the Commercial Arbitration Rules of the American
Arbitration Association. The arbitration award shall be in writing and shall be
final and binding, and judgment on the award may be entered in any court having
jurisdiction thereof.

               12.12 Governing Law. This Agreement shall be governed by,
enforced and construed in accordance with the laws of the State of Delaware,
without regard to choice of law principles.

               12.13 Specific Performance. Notwithstanding anything herein to
the contrary, if Buyer, Sellers or the Shareholder fails to perform any of its
obligations under this Agreement, the aggrieved party shall have the right, in
addition to all other rights or remedies, to specific performance of the terms
hereof.

               12.14 Headings. Subject headings are included for convenience
only and shall not effect the interpretation of any provisions of this
Agreement.

               12.15 Waiver of Jury Trial. To the extent permitted by applicable
law, Buyer, Sellers and the Shareholder hereby waive trial by jury in any
litigation in any court with respect to, in connection with, or arising out of
this Agreement, the Security Agreement or the CPAN Promissory Note, or any
document related to this Agreement, the Security Agreement or the CPAN
Promissory Note, or the validity, protection, interpretation, collection or
enforcement of this Agreement, the Security Agreement or the CPAN Promissory
Note. Buyer, Sellers and the Shareholder agree that this provision is a specific
and material aspect of this Agreement and acknowledge that the other parties
hereto would not enter into this Agreement if this section were not part of the
Agreement, the Security Agreement and the CPAN Promissory Note.

Dear ___________:

Leap Wireless International, Inc. ("Leap"), MVI Corp., Century Personal Access
Network, Inc., Wisconsin RSA #7, Limited Partnership, and Centurytel, Inc.
(collectively, "Centurytel") are parties to that certain Agreement For Purchase
and Sale of Licenses dated as of November __, 2000 (the "Agreement"). Leap
desires to immediately commence radio test transmissions and analyses of the
spectrum covered by Centurytel's Personal Communications Services FCC
Licenses(s) for the Basic Trading Areas described on the exhibit attached
hereto. For purposes of this testing and analysis, Leap and/or a third party
equipment vendor will need to operate various pieces of radio transmitting and
receiving equipment in portions of the frequency bands authorized for use under
Centurytel's Licenses for the purposes of conducting technical trials. These
tests will not involve paying customers or the provision of commercial
telecommunications service.

This letter is intended to further memorialize Centurytel's consent to and
authorization of such testing, consistent with the terms of the Agreement. We
acknowledge that Centurytel continues to remain responsible for complying with
all of the operating conditions and requirements associated with the Licenses
pending the completion of the transaction between our companies. Furthermore,
Leap agrees that in conducting its tests, Leap will ensure that (i) all
equipment used for the tests operating in the relevant spectrum covered by
Centurytel's Licenses will comply with all material FCC requirements for use of
this spectrum; (ii) that Leap or any third party conducting testing at Leap's
direction will cease transmission of its equipment immediately upon the written
request of Centurytel, and (iii) Leap will provide access to Centurytel's
representatives to these tests if and as Centurytel may desire. Leap further
agrees that the testing and analysis to be conducted by Leap will not interfere
with the use of any spectrum other than Centurytel's Licenses, nor interfere
with any commercial services currently operated by Centurytel under the
Centurytel Licenses.

Please indicate your agreement with the aforesaid by countersigning this letter
below.


                                          Sincerely,



                                          Robert F. Anselmo
