company, duly organized and validly existing under the laws of the state of its
formation. Seller has all requisite limited liability company power and
authority to conduct the business contemplated by it and to own, lease and
operate any properties or assets in connection therewith, and has applied for
qualification or is duly qualified to do business as a foreign limited liability
company in good standing in those jurisdictions, other than the state of its
organization, in which the nature of the business conducted or property owned by
it makes such qualification necessary, except where the failure to be so
qualified or in good standing would not materially adversely affect the ability
of Seller to consummate the transactions contemplated by this Agreement.

               4.2 Authority of Seller. Seller has full power and authority to
own and to operate the Licenses. Seller has full power and authority to execute,

insolvency, reorganization, moratorium, and similar laws affecting the rights of
creditors generally, and general principles of equity.

               4.3 No Conflicts. Except for the FCC Consent and the filing
under, and the expiration or termination of applicable waiting period under, the
HSR Act, neither the execution or delivery of this Agreement nor the
consummation of any of the transactions contemplated hereby or compliance with
or fulfillment of the terms, conditions and provisions hereof will (i) result in
the creation or imposition of any Encumbrance upon any of the Licenses, 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, modification or cancellation or a loss of
rights under, or require any notice to, authorization or approval of, filing
with or consent under (1) Seller's certificate of formation or limited liability
company operating agreement or by-laws; (2) the FCC Note and Security Agreement;

               4.4 The Licenses. Seller validly holds the Licenses. Seller has
not commenced or otherwise undertaken any system build-out activities with
respect to the Licenses and has conducted no operations with respect thereto.
Seller has performed as of the Effective Date, and will have performed as of the
respective Closing Dates (other than any required buildout activities), all of
its obligations required to have been performed under the Licenses, and, except
as described in Exhibit D, no event has occurred or condition or state of facts
exists which constitutes or, after notice or lapse of time or both, would
constitute a breach or default under any of the Licenses or the FCC Note and
Security Agreement which permits or, after notice or lapse of time or both,
would permit revocation or termination of any of the Licenses, or which might
adversely affect in any material respect the rights of Seller under any of the
Licenses; no notice of cancellation, of default or of any dispute concerning any
of the Licenses, or of any event, condition or state of facts described in the
preceding clause, has been received by, or is known to, Seller; and each License
is 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, the execution by Buyer of a note and security agreement with the FCC
for the Denver License, and the filing under, and expiration or termination of
the applicable waiting period under, the HSR Act, the consent, approval, or act
of, or the making of any filing with, any Governmental Body. Seller has no
reason to believe that the Licenses are not likely to be renewed in the ordinary
course or that the holder of such Licenses would not be entitled to renewal
expectancy as contemplated by FCC rules and regulations. Each of the Licenses
(i) was granted on the grant date specified on Exhibit A, (ii) expires on the
expiration date specified on Exhibit A, and (iii) is subject to the five-year
construction milestone date occurring on the date specified on Exhibit A.

               4.5 Title to Licenses. Seller has good and marketable title to
all of the Licenses, free and clear of all Encumbrances, except for the FCC Note
and Security Agreement relating to the Denver License. Upon delivery to Buyer on
each Closing Date, Seller will transfer to Buyer good and marketable title to
the respective License, subject to no Encumbrances, except for the FCC Note and
Security Agreement.

               (a) The Licenses comply in all material respects with all
applicable Requirements of Law;

               (c) There is no investigation, claim, action, suit or other
proceeding pending or, to the best knowledge of Seller, threatened against
Seller, relating to Seller or the Licenses which, if adversely determined,
either would result in the revocation, cancellation, suspension or adverse
modification of any of the Licenses or would have a material adverse effect on
the ability of Seller to perform its obligations hereunder or upon the financial
condition, assets, business,

                                       7
<PAGE>   8

prospects or results of operations of Seller, nor is Seller 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 Seller
in connection with the transactions contemplated hereby.

               4.8 Restricted Securities.

        (a) Seller understands that the Leap Shares are characterized as
"restricted securities" under the Securities Act of 1933 (as amended and
together with the rules and regulations promulgated thereunder, the "Securities
Act") and that, under the Securities Act and applicable regulations thereunder,
such securities may not be resold, pledged or otherwise transferred without
registration under the Securities Act except in certain limited circumstances.
Seller understands that (i) the Leap Shares are being offered in a transaction
not involving any public offering in the United States within the meaning of the
Securities Act, and the Leap Shares have not yet been registered under the Act,
and (ii) such Leap Shares may be offered, resold, pledged or otherwise
transferred only in a transaction registered under the Securities Act, or
meeting the requirements of Rule 144, or in accordance with another exemption
from the registration requirements of the Act (and based upon an opinion of
counsel if Buyer so requests) and in accordance with any applicable securities
laws of any State of the United States or any other applicable jurisdiction.

        (b) Seller understands that (i) the registrar or transfer agent for the
Leap Shares will not be required to accept for registration of transfer any Leap
Shares except upon presentation of evidence satisfactory to Buyer that the
restrictions on transfer under the Securities Act have been complied with and
(ii) any Leap Shares in the form of definitive physical certificates will bear a
legend substantially as set forth below:

               "THE SECURITIES EVIDENCED HEREBY WERE ORIGINALLY ISSUED IN A
               TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE
               UNITED STATES SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND
               APPLICABLE STATE SECURITIES LAWS, AND THE SECURITIES EVIDENCED
               HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
               ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
               THEREFROM. THE HOLDER OF THE SECURITIES EVIDENCED HEREBY AGREES
               FOR THE BENEFIT OF THE CORPORATION THAT (A) SUCH SECURITIES MAY
               NOT BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, EXCEPT (1) IN A
               TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE
               SECURITIES ACT, OR IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
               REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON
               AN OPINION OF COUNSEL IF THE CORPORATION SO REQUESTS), (2) TO THE
               CORPORATION, OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION
               STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE, IN ACCORDANCE
               WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED

                                       8
<PAGE>   9

               STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER
               WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY
               PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE
               RESTRICTIONS SET FORTH IN (A) ABOVE."

               4.9 Investment. Seller (a) understands that the Leap Shares have
not been registered under the Securities Act, or under any state securities
laws, and are being offered and sold in reliance upon federal and state
exemptions for transactions not involving any public offering, (b) is acquiring
the Leap Shares solely for its own account for investment purposes, and not with
a view to the distribution thereof in a transaction that would violate the
Securities Act or the securities laws of any State of the United States or any
other applicable jurisdiction, (c) is a sophisticated purchaser with such
knowledge and experience in business and financial matters that Seller is
capable of evaluating the merits and risks of purchasing the Leap Shares, (d)
has received certain information concerning Buyer and its subsidiaries and has
had the opportunity to obtain additional information as desired in order to
evaluate the merits and the risks inherent in holding the Leap Shares, (e) is
able to bear the economic risk and lack of liquidity inherent in holding the
Leap Shares, and (f) is an "accredited investor" within the meaning of Rule
501(a) under the Securities Act.

               4.10 FCC Matters.

               (a) The Licenses are validly issued in the name of Seller. Seller
        and its subsidiaries applied for and obtained the Licenses in compliance
        with FCC law, and Seller is, and on each applicable Closing Date will
        be, the exclusive holder 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 Seller and its affiliates,
        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 licensees and/or the wireless telecommunications industry
        generally. All reports and other documents required to be filed by
        Seller and its affiliates with the FCC and with state regulatory
        authorities have been filed. All such reports and documents are correct
        in all material respects.

               (b) None of the Seller or its subsidiaries have engaged in any
        course of conduct which would impair the Seller's ability to remain the
        holder of the FCC licenses and such persons are not aware of any reason
        why such Licenses might be revoked, canceled, suspended or otherwise
        transferred as a result of the transactions contemplated hereby. All
        material fees of Seller and its subsidiaries due and payable to
        governmental authorities pursuant to the Licenses have been paid
        (subject to late fees paid). Subject to obtaining the consent of the FCC
        to assign the Licenses to Buyer, Seller has, and on the Closing Date
        will have, the absolute and unrestricted right, power and authority
        under FCC law to hold the Licenses.

               (c) Seller and its subsidiaries 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.

full power and authority to execute, deliver and perform this Agreement and any
agreement, document or instrument executed and delivered pursuant to this
Agreement or in connection with this Agreement. The execution, delivery and
performance of this Agreement and any agreement, document or instrument executed

Buyer of a note and security agreement with the FCC for the Denver License, and
the filing under and expiration or termination of the applicable waiting period
under the HSR Act, neither the execution and delivery of this Agreement nor the
consummation of any of the transactions contemplated hereby nor compliance with
or fulfillment of the terms, conditions and provisions hereof will:

               (a) 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 or cancellation or a loss of rights under:

indenture instrument, agreement, license, permit or other right or obligation to
which Buyer is a party or any of its properties is subject or by which Buyer is
bound; (3) any Court Order to which Buyer is a party or by which it is bound; or
(4) any Requirements of Laws affecting Buyer.

               (b) Require the approval, consent, authorization or act of, or

or, to Buyer's knowledge, threatened against Buyer, which if adversely
determined, would have a material adverse effect on the ability of Buyer to
perform its obligations hereunder, or upon the financial condition, assets,
business, prospects or results of operations of Buyer, nor is Buyer aware of any
reasonable basis for any such investigation, claim, suit or proceeding.

               5.6. Qualification. Buyer or its designated subsidiary 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 from any state
or local regulatory authority necessary for it to acquire the Licenses.

               5.7 Leap Shares. The Leap Shares to be issued to Seller in
exchange for the consideration set forth in this Agreement, when issued and
delivered in accordance with the terms and conditions hereof, will be duly
authorized, fully paid, validly issued and non-assessable.

                                   ARTICLE VI
                        ACTION PRIOR TO THE CLOSING DATE

               The parties hereto covenant and agree to take the following
actions between the date hereof and the final Closing Date:

               6.1 Investigation by Buyer. Seller shall afford to Buyer and its
authorized representatives reasonable access during normal business hours to the
Licenses and Seller to the extent Buyer shall deem reasonably necessary or
desirable and shall furnish to Buyer or its authorized representatives such
additional information concerning the Licenses and Seller 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 Seller
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 Seller 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 any 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. Seller will act diligently and reasonably to
secure, before each applicable 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 respective License to Buyer or to
otherwise satisfy the conditions set forth herein; provided that neither Seller
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 Seller
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 each applicable
Closing Date, Buyer shall act diligently and reasonably to cooperate with Seller
to obtain the consents, approvals and waivers contemplated by this Section
6.3(a).

               (b) FCC Consents. Seller and Buyer shall, as promptly as
practicable from the date of this Agreement, file with the FCC an FCC Form 603
(or other appropriate form) applications seeking consent to assign each
respective License from Seller to Buyer or Buyer's subsidiary. The parties shall
cooperate and use their respective reasonable efforts to prosecute such
applications to a favorable conclusion and shall share equally any filing fees.

               (c) HSR Filing. Following the execution and delivery of this
Agreement, Buyer and Seller will take such action, if any, as may be required to
be taken by them under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act") in connection with the transactions contemplated
hereby. Each party will cooperate in the preparation of, 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
authority 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 authority 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. Except for the application fee of
Buyer, which shall be paid in full by the Buyer, each of Buyer and Seller shall
bear their respective costs for such compliance under this Section 6.3(c).

               6.4 Operations Prior to the Closing Dates. At all times prior to
the final License Closing, Seller 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 due to the FCC with
respect to the Denver License on a timely basis. Seller shall retain control of
the Licenses at all times prior to the respective Closing. Seller shall not:

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

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

               6.5 Registration Statement for Resale of Leap Shares.

               (a) Shelf Registration Statement. Not later than sixty (60) days
prior to the expected Denver Closing Date, Buyer will file with the Securities
and Exchange Commission (the "SEC") a shelf registration statement under the
Securities Act of 1933 (as amended and together with the rules and regulations
promulgated thereunder, the "Securities Act") registering the Leap Shares for
resale to the public by Seller pursuant to such registration statement and the
prospectus included therein (the "Registration Statement"), free and clear of
any restrictions under the Securities Act except for prospectus delivery
requirements. Buyer shall use all reasonable efforts to cause such Registration
Statement to become effective as promptly as practicable thereafter and, subject
to Section 6.5(b), to remain effective until the expiration of the Resale Period
(as defined in Section 6.5(b) below). Seller agrees to cooperate with and
provide assistance to Buyer, as Buyer may reasonably request, in connection with
any registration and sale of the Leap Shares.

               (b) Buyer Obligations. From time to time during the period
commencing on the Denver Closing Date and ending upon the earlier of (x) the
first anniversary of the Denver Closing Date, or (y) such time as Seller shall
have advised Buyer in writing that it has completed its resale of the Leap
Shares delivered hereunder (the "Resale Period") , Buyer shall do the following:

                (i) Prepare and deliver to Seller as many copies of the
        Prospectus (as hereafter defined) and other documents incident thereto,
        including any amendment or supplement to the Prospectus, as Seller may
        from time to time reasonably request;

                (ii) Use its reasonable efforts to comply with all requirements
        imposed upon it by the Securities Act, by the Securities Exchange Act of
        1934 (as amended and together with the rules and regulations promulgated
        thereunder, the "Exchange Act"), and by the undertakings in the
        Registration Statement (including but not limited to the undertakings
        required by Item 512(g) of Regulation S-K) so far as is necessary to
        permit the continuance of resales of Leap Shares by Seller to the
        public, free and clear of any restrictions under the Securities Act
        except for prospectus delivery requirements, including the preparation
        and filing with the SEC of such amendment and supplements to such
        Registration Statement as may be necessary to comply with the provisions
        of the Securities Act. If, at any time during the Resale Period, an
        event shall occur which makes it necessary to amend or supplement the
        Registration Statement or the Prospectus to comply with law or with the
        rules and regulations of the SEC, Buyer shall forthwith notify Seller of
        the proposed amendment or supplement and prepare and furnish to Seller
        such number of copies of an amended or supplemented Registration
        Statement or Prospectus that complies with law and with such rules and
        regulations as Seller may reasonably request. Seller shall suspend its
        sales of Leap Shares pending the preparation and delivery of such
        amendment or supplement and until such time as each such amendment or
        amendments to the Registration Statement has been declared effective by
        the SEC. Buyer authorizes Seller, and any brokers or dealers effecting
        sales of the Leap Shares for the account of Seller, to use the
        Prospectus, as from time to time amended or supplemented,

                                       13
<PAGE>   14

        in connection with the sale of the Leap Shares in accordance with
        applicable provisions of the Securities Act and state securities laws.
        For purposes of this Agreement, the term "Prospectus" means the final
        prospectus relating to the Leap Shares most recently included in the
        Registration Statement or filed by Buyer pursuant to Rule 424 of the
        Securities Act and any amendments or supplements thereto filed by Buyer
        pursuant to Rule 424 of the Securities Act and shall include all
        documents or information incorporated in any such prospectus by
        reference;

                (iii) Promptly advise Seller (A) when any post-effective
        amendment of the Registration Statement is filed with the SEC and when
        any post-effective amendment becomes effective; (B) of any request made
        by the SEC for any amendment of or supplement to the Registration
        Statement or the Prospectus or for additional information relating
        thereto; (C) of any suspension or threatened suspension of the use of
        any Prospectus in any state; and (D) of any proceedings commenced or
        threatened to be commenced by the SEC or any state securities commission
        which would result in the issuance of any stop order or other order or
        suspension of use. Buyer agrees to use its reasonable efforts to prevent
        or promptly remove any stop order or other order preventing or
        suspending the use of the Prospectus during the Resale Period at the
        earliest practicable date, and to comply with any such request by the
        SEC to amend or supplement the Prospectus;

                (iv) Take such action as shall be necessary to qualify and
        maintain the qualification of the Leap Shares covered by such
        registration under such state securities or "blue sky" laws of those
        jurisdictions within the United States and Puerto Rico as shall be
        reasonably required to effect offers and sales to the public during the
        Resale Period as Seller shall reasonably request; provided, however,
        that Buyer shall not be obligated to qualify as a foreign corporation to
        do business under the laws of or become subject to taxation in, any
        jurisdiction in which it shall not be then qualified, or to file any
        general consent to service of process;

                (v) Cause the Leap Shares to be registered pursuant to Section
        12(b) or 12(g) of the Exchange Act and continually listed, subject to
        notice of issuance, on the NASDAQ-NMS or a national securities exchange,
        if such exchange is the principal market on which the Leap Shares are
        traded, and not subject to any restriction or suspension from trading on
        the NASDAQ-NMS or such national securities exchange; provided, however,
        that Buyer may deregister the Leap Shares registered pursuant to Section
        12(b) or 12(g) of the Exchange Act if such deregistration is in
        connection with a merger, dissolution or other transaction in which the
        shareholders of Buyer receive prior to such deregistration either cash
        or securities that are listed on the NASDAQ-NMS or a national securities
        exchange or some combination of cash and such securities; provided,
        further, that Buyer may delist the Leap Shares from trading on the
        NASDAQ-NMS or national securities exchange if Buyer is concurrently
        listing such stock on the New York Stock Exchange or the American Stock
        Exchange;

                (vi) Provide a transfer agent and registrar for the Leap Shares
        registered pursuant to such Registration Statement, not later than the
        effective date of such

                                       14
<PAGE>   15

        registration; and

                (vii) Otherwise use its reasonable efforts to comply with all
        applicable rules and regulations of the SEC, and make available to
        security holders earnings statements satisfying the provisions of
        Section 11(a) of the Securities Act, no later than 45 days after the end
        of any 12-month period (or 90 days, if such period is a fiscal year),
        beginning with the first month of the Company's first fiscal quarter
        commencing after the effective date of the Registration Statement, which
        earnings statements shall cover said 12-month periods.

               (c) Indemnification of Seller. Buyer shall indemnify, defend and
hold harmless Seller, its officers and its directors and any controlling persons
of Seller against and in respect of any losses, claims, damages or liabilities,
joint or several (including legal or other fees and expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage or liability) to which Seller or any of them may become subject under the
Securities Act or otherwise insofar as such losses, claims, damages or
liabilities (or actions with respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except to the extent
that any such untrue statement or omission is based upon written information
supplied by Seller or by any of its representatives for use in such Registration
Statement; provided, however, this indemnity agreement shall not inure to the
benefit of Seller, its officers or its directors or any controlling persons of
Seller on account of any loss, claim, damage, liability or action arising from
the sale of Leap Shares to any person if Seller fails to send or give a copy of
the Prospectus (as amended or supplemented) to such person.

               (d) Indemnification of Buyer. Seller shall indemnify, defend and
hold harmless Buyer, its officers and its directors and any controlling persons
of Buyer against and in respect of any losses, claims, damages or liabilities,
joint or several (including legal or other fees and expenses reasonably incurred
by any of them in connection with investigating or defending any such loss,
claim, damage or liability) to which Buyer or any such persons may become
subject under the Securities Act or otherwise insofar as such losses, claims,
damages or liabilities (or actions with respect thereto) arise out of or are
based upon any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, but
only to the extent that any such untrue statement or omission is based upon
written information with respect to the plan of distribution of Seller supplied
by Seller or its representatives for use in such Registration Statement.

               (e) Contribution. If for any reason the indemnification provided
for in the preceding clauses (c) and (d) is unavailable to an indemnified party
as contemplated by the such clauses, then the indemnifying party shall
contribute to the amount paid or payable by the indemnified party as a result of
such loss, claim, damage or liability in such proportion as is appropriate to
reflect not only the relative benefits received by the indemnified party and the
indemnifying party, but also the relative fault of the indemnified party and the
indemnifying party,

                                       15
<PAGE>   16

as well as any other relevant equitable considerations.

               (f) Procedure for Indemnification The procedure for
indemnification shall be as follows:

                (i) Notice. The indemnified party shall promptly give notice to
        the indemnifying party of any pending or threatened claim giving rise to
        indemnification under subsections 6.5(c) or (d) (a "Claim"), specifying
        the factual basis for the Claim and the approximate amount thereof.

                (ii) Control of Claim and Settlement. With respect to any Claim
        as to which a person is entitled to indemnification hereunder, the
        indemnifying party shall have the right at its own expense to
        participate in or assume control of the defense of the Claim, and the
        indemnified party shall cooperate fully with the indemnifying party,
        subject to reimbursement for actual out-of-pocket expenses incurred by
        the indemnified party as the result of a request by the indemnifying
        party. If the indemnifying party elects to assume control of the defense
        of any Claim, the indemnified party shall have the right to participate
        in the defense of the Claim at its own expense. If the indemnifying
        party does not elect to assume control or otherwise participate in the
        defense of any Claim, it shall be bound by the results obtained by the
        indemnified party with respect to the Claim. No indemnifying party shall
        be liable for any settlement effected without its written consent, not
        to be unreasonably withheld or delayed.

               (g) Survival. Notwithstanding any other provision of this
Agreement, the indemnification obligations of the parties hereunder shall
survive indefinitely. The provisions set forth in Article X hereof shall not
apply to any facts or circumstances, which are the subject of indemnification
pursuant to Sections 6.5(c) or 6.5(d).

               (h) Expenses. Buyer shall pay all expenses incident to the
registration of the Leap Shares under this Section 6.5, including without
limitation, all registration, filing and NASD fees, all fees and expenses of
complying with securities or blue sky laws, all word processing, duplicating and
printing expenses, and the fees and disbursements of counsel for Buyer and its
independent public accountants. With respect to sales of Leap Shares, Seller
shall pay all underwriting discounts and commissions and fees of underwriters,
selling brokers, dealer managers or similar securities industry professionals
relating to the distribution of the Leap Shares, the fees and disbursements of
counsel retained by Seller and transfer taxes, if any.

               (i) Seller Information. Notwithstanding anything in this
Agreement to the contrary, if Seller shall have failed to provide all
information to Buyer required to be included in the Registration Statement as to
Seller in sufficient time prior to the Denver Closing Date to enable Buyer to
fulfill its filing obligations under Section 6.5(a) on a timely basis, then (A)
the condition set forth in Section 9.4 shall not be a condition precedent to the
Denver Closing and (B) the date by which Buyer must file the Registration
Statement under Section 6.5(a) shall be extended a reasonable period of time to
reflect the delay caused by Seller's failure to deliver the requisite
information to Buyer.

                                       16
<PAGE>   17

               (j) Compliance. Seller will observe and comply with the
Securities Act and the general rules and regulations thereunder, as now in
effect and as from time to time amended and including those hereafter enacted or
promulgated, in connection with any offer, sale, pledge, transfer or other
disposition of the Leap Shares or any part thereof.

               6.6 Exclusivity. Until the termination of this Agreement, Seller
will not (and the Seller will cause each of its members, managers and 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. Seller 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.

                                   ARTICLE VII
                              ADDITIONAL AGREEMENTS

               7.1 Non-Competition. Effective at and as of the Closing:

               (a) Seller, its members, executive officers and principals
covenant and agree, for themselves and their respective affiliates, that for a
period of two (2) years after the respective Closing, such persons, and their
respective affiliates shall not, directly or indirectly, engage in any
activities that may compete with Buyer within the BTAs covered by the respective
License. If, in any judicial proceeding, a court shall refuse to enforce any of
the separate covenants deemed included in this Section 7.1, then such
unenforceable covenant shall be deemed eliminated from these provisions to the
extent necessary to permit the remaining separate covenants to be enforced.

               (b) The words "directly or indirectly" as they relate to any
activity prohibited by the terms of this Section 7.1, mean (i) acting as an
agent, representative, consultant, officer, director, partner, employee or
independent contractor of any entity or enterprise that engages in any such
activity; or (ii) participating in any such entity or enterprise as an owner,
partner, limited partner, joint venturer, creditor or stockholder (except as a
stockholder holding less than one percent (1%) interest in a corporation whose
shares are actively traded on a regional or national securities exchange or in
the over-the-counter market).

               7.2 Reasonable Efforts. Subject to the terms and conditions
herein, each of the parties hereto agrees to use all commercially reasonably
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, all things reasonably necessary, proper or advisable under applicable laws
and regulations to consummate and make effective the transactions contemplated
by this Agreement as promptly as practicable. In case at any time after a
Closing any further action is reasonably necessary to carry out the purposes of
this Agreement, the proper agents, officers and directors of each party hereto
shall take such action.

                                       17
<PAGE>   18

               7.3 Governmental Authorizations. Seller shall not cause or
permit, by any act or failure to act, any of its governmental authorizations or
Licenses to expire or to be surrendered or modified, or take any action that
would cause any governmental authority 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 authority in connection with the Licenses.

               7.4 Market Stand-Off. If at any time Buyer conducts an
underwritten public offering of its Common Stock or other securities, Seller
agrees that it will not, without the prior consent of the underwriters of such
public offering, during the period commencing on the date of the pricing of such
public offering and ending on the earlier of ninety (90) days after the date of
the final prospectus relating to such public offering or June 30, 2000, (a)
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any
shares of Leap Common Stock or any securities convertible into or exercisable or
exchangeable for Leap Common Stock or (b) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of Leap Common Stock, whether any such transaction
described in clause (a) or (b) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise. The provisions of this
Section 7.4 shall also be for the benefit of Buyer's underwriters in any such
public offering, who shall be deemed to be express third party beneficiaries of
this Section 7.4. Seller agrees to execute and deliver a customary "lock-up"
agreement with Buyer's underwriters in any such public offering containing
substantially the same terms and conditions as this Section 7.4 if requested by
Buyer's underwriters to do so.

                                    ARTICLE X
                                 INDEMNIFICATION

               10.1 Survival. All of the representations and warranties of the
Parties contained in Article IV or Article V shall survive the final Closing
hereunder (even if the other Party knew or had reason to know of any
misrepresentation or breach of warranty at the time of such Closing) and shall
continue in full force and effect until the three (3) year anniversary of the
final Closing Date, except that the representations and warranties set forth in
Sections 4.2, 4.5 and 4.6 shall survive the final Closing and continue in full
force and effect forever thereafter.

               10.2 Indemnification by Seller. In the event Seller breaches (or
in the event any third party alleges facts that, if true, would mean the Seller
has breached) any of its representations, warranties, and 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 Seller 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 Seller's ownership or
operation of any License prior to the respective Closing therefor, then the
Seller agrees to indemnify the Buyer and its directors, officers, stockholders,
agents, successors and assigns from and against the entirety of any Losses or
Expenses any such person may incur through and after the date of the claim for
indemnification resulting from, arising out of, relating to, in the nature of,
or caused by the breach (or the alleged breach), or such claim, action suit or
proceeding.

               10.3 Indemnification by Buyer. In the event Buyer breaches (or in
the event any third party alleges facts that, if true, would mean Buyer has
breached) any of its representations, warranties, and covenants contained herein
and, if there is an applicable survival period pursuant to Section 10.1 above
and the Seller makes a written claim against Buyer within such period, or in the
event of any actual or threatened claim, action, suit or proceeding against
Seller or any of its subsidiaries arising from Buyer's ownership or operation of
PCS Systems under the Licenses following the respective Closings therefor, then
Buyer agrees to indemnify Seller and its directors, officers, stockholders,
agents, successors and assigns from and against the entirety of any Losses or
Expenses any such person may incur through and after the date of the claim for
indemnification resulting from, arising out of, relating to, in the nature of,
or caused by the breach (or the alleged breach), or such claim, action, suit or
proceeding.

               10.4 Certain Limitations. Notwithstanding any provision of this
Agreement to the contrary:

               (a) The maximum aggregate liability of Seller or Buyer pursuant
to its indemnification obligations under Section 10.2 or Section 10.3,
respectively, shall be $33,400,000; provided, that such amount shall be reduced
by $15,030,000 if this Agreement is terminated with respect to the Denver
License prior to the Closing thereof, or by $18,370,000 if

                                       20
<PAGE>   21

this Agreement is terminated with respect to the Pittsburgh License prior to the
Closing thereof; and

               (b) The provisions of Article X shall not apply to any Claims,
Losses or Expenses incurred arising from or related to any material misstatement
contained in or material omission from the Registration Statement or Prospectus
contemplated by Section 6.5 hereof. The indemnification and contribution
provisions under Section 6.5 shall apply exclusively to any such Claims, Losses
or Expenses.

               10.5 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 in respect of any action at law or
suit in equity by or against a third Person as to which indemnification will be
sought shall be given promptly after the action or suit is commenced; 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 10.4, 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) 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.

               10.6 Third Person Claims.

               (a) Subject to Section 10.6(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

                                       21
<PAGE>   22

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 or, where the Seller is the
Indemnitor will have no continuing effect in any material respects 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 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.

               10.7 Amount of Indemnification Payments. In calculating any Loss
or Expense there shall be deducted (i) any insurance recovery in respect thereof
(and no right of subrogation shall accrue hereunder to any insurer) and (ii) the
net present value of any actual tax benefit to the Indemnified Party (or any of
its affiliates) with respect to such Loss or Expense (after taking into account
the actual tax effect of receipt of the indemnification payments).

                                   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 Seller and Buyer;

               (b) by either Buyer or Seller 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

                                       22
<PAGE>   23

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 terminate this
Agreement, (iii) specifies in such Termination Notice the representation,
warranty or covenant of which the Breaching Party is allegedly in material
breach, and (iv) provides the Breaching Party with thirty (30) days within which
to cure such alleged breach, unless such alleged breach may not reasonably be
cured within such 30-day period;

               (c) by either Buyer or Seller upon written notice to the other,
upon the other party's filing, 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 or Seller 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 the
transactions contemplated by this Agreement, and such order, decree, ruling or
other action shall have become final and non-appealable;

               (e) by Buyer upon written notice to Seller upon the occurrence of
a "Seller Default" (as defined below); or

               (f) by either Buyer or Seller upon twenty (20) days' prior
written notice of such termination, if the Pittsburgh Closing or the Denver
Closing, or both of them, shall not have occurred on or before the nine (9)
month anniversary of the Effective Date of this Agreement; provided, however,
that if one of the Closings has occurred prior to such termination, this
Agreement shall continue in full force and effect in accordance with its terms
with respect to the particular License for which the Closing already had been
consummated.

For purposes of Section 11.1(e) above, "Seller Default" means: (1) Seller or any
of its subsidiaries has failed to make any payments when due of any principal,
interest, fees, lease rentals, or any and all other amounts owed to third
parties in an aggregate amount in excess of $50,000; (2) Seller or any of its
subsidiaries have breached the Licenses, have failed to make payments of
principal or accrued interest such that Seller cannot deliver good title to the
respective Licenses to Buyer, or have failed to continue to hold the Licenses,
directly or indirectly free and clear of all liens and Encumbrances; (3) the
occurrence of a Material Adverse Change with respect to Seller and its
subsidiaries; (4) Seller or any of its subsidiaries have suffered a material
lapse in the customary types and amounts of insurance coverage carried for their
business, (5) Seller or any of its subsidiaries has defaulted on any of its
outstanding indebtedness to third parties having a principal amount exceeding
$250,000, whether as a result of the failure to pay money or otherwise; (6)
Seller or any of its subsidiaries becomes insolvent, or is unable to pay its
debts as they become due, or makes an assignment for the benefit of creditors,
or files a voluntary petition in bankruptcy, or suffers the filing of an
involuntary petition in bankruptcy, or seeks protection from creditors under any
state law provision, or becomes subject to the appointment of a trustee or
receiver over its assets; or (7) one or more judgments have been entered against
Seller or any of its subsidiaries involving an aggregate amount of greater than
$250,000.

               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). The provisions of Sections 6.5(c)-(g), Article X and Sections
11.2, 12.1, 12.6, 12.7, 12.11, 12.12, 12.13, and 12.14 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 the terms and provisions of this Agreement or from any obligations that exist
under separate agreements between the parties.

                                   ARTICLE XII
                               GENERAL PROVISIONS

               12.1 Confidential Nature of Information. Each party agrees that
it will treat in confidence all documents, materials and other information which
it shall have obtained regarding the other party during the course of the
negotiations leading to the consummation of the transactions contemplated hereby
(whether obtained before or after the date of this Agreement), the investigation
provided for herein and the preparation of this Agreement and other related
documents. Such documents, materials and information shall not be communicated
to any third Person except to employees, representatives or partners of Buyer or
Seller with a need to know and such persons shall be informed of the
confidential nature of such information. No party shall use any confidential
information in any manner whatsoever except solely for the purpose of evaluating
the proposed purchase and sale of the Licenses. The obligation of each party to
treat such documents, materials and other information in confidence shall not
apply to any information which (i) is or becomes available to a party hereto
from a source other than another party hereto, (ii) is or becomes available to
the public other than as a result of disclosure by a party or its agents, (iii)
is required to be disclosed under applicable law or judicial process, but only
to the extent it must be disclosed, or (iv) is independently developed by such
party without reference to the confidential information of the other party; (v)
a party reasonably deems necessary to disclose to in order to obtain any of the
consents or approvals contemplated hereby. To the extent the provisions of this
paragraph conflict with the existing Non-Disclosure Agreement ("NDA") between
the parties, the provisions of the NDA shall prevail.

               12.2 No Public Announcement. No party shall, without the approval
of the other, make any press release or other public announcement concerning the
transactions contemplated by this Agreement, except as and to the extent that
any such party shall be so obligated by law, in which case the other party shall
be advised and the parties shall use their reasonable efforts to cause a
mutually agreeable release or announcement to be issued; provided that the
foregoing shall not preclude communications or disclosures necessary to
implement the provisions of this Agreement or to comply with accounting and
Securities and Exchange Commission disclosure obligations or applicable FCC
disclosure obligations.

               12.4 Successors and Assigns.

               (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 of Buyer hereunder may be assigned prior to
the Closing, without the consent of Seller, to any of its affiliates,
subsidiaries, successors and assigns ("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
Buyer, any Permitted Assignees as well as the successors in interest to such
Permitted Assignee. Except pursuant to Section 7.4, nothing in this Agreement,
expressed or implied, is intended or shall be construed to confer upon any
Person other than the parties and successors and Permitted Assignees, any right,
remedy or claim under or by 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
or letters of intent between or among any of the parties hereto, including the
Memorandum of Understanding entered into as of December 7, 1999 by and between
the parties. This Agreement shall not be amended, modified or supplemented
except by a written instrument signed by an authorized representative of each of
the parties hereto.

               12.6 Waivers. Any failure of either Buyer or Seller to comply
with any obligation, covenant, agreement or condition herein may be waived by
the other party only by a written instrument signed by the party 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 and thereby, including
the fees, expenses and disbursements of its counsel and advisors. In the event
either party shall bring an action in connection with the performance, breach or
interpretation of this Agreement, the prevailing party in any such action shall
be entitled to recover from the losing party all reasonable costs and expenses
of such action, 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

                                       26
<PAGE>   27

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, 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, Seller 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,
any part of the Licenses.

               12.11 Resolution of Disputes. Except with respect to a breach of
the obligations of confidentiality, non-competition and actions detrimental to
the acquisition of the Licenses contemplated hereunder, as to which the
non-breaching party shall have the right to seek injunctive remedy or other
equitable remedies, senior management employees of Buyer and Seller 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

                  (v) to approve forms of agreement for use under the Plan;

                  (vi) to determine the terms and conditions,  not  inconsistent

conditions  include,  but are not limited to, the  exercise  price,  the time or
times  when  Options  may be  exercised  (which  may  be  based  on  performance
criteria),  any vesting acceleration or waiver of forfeiture  restrictions,  and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto,  based in each case on such factors as the  Administrator,  in
its sole discretion, shall determine;

                  (vii) to reduce the  exercise  price of any Option to the then

                  (viii) to institute an Option Exchange Program;

                  (ix) to  construe  and  interpret  the  terms  of the Plan and
awards granted pursuant to the Plan;

                  (x) to  prescribe,  amend and  rescind  rules and  regulations
relating to the Plan,  including  rules and  regulations  relating to  sub-plans
established  for the purpose of qualifying  for  preferred  tax treatment  under
foreign tax laws;

                  (xi) to modify or amend each Option  (subject to Section 14(b)
of  the   Plan),   including   the   discretionary   authority   to  extend  the
post-termination  exercisability  period of  Options  longer  than is  otherwise
provided for in the Plan;

                  (xii) to  authorize  any  person to  execute  on behalf of the
Company any  instrument  required to effect the grant of an Option or previously
granted by the Administrator;

                  (xiii) to determine the terms and  restrictions  applicable to
Options;

                  (xiv)  to  allow   Optionees   to  satisfy   withholding   tax
obligations  by  electing  to have the  Company  withhold  from the Shares to be
issued upon exercise of an Option or Stock  Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld  shall be  determined on the date that
the  amount of tax to be  withheld  is to be  determined.  All  elections  by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable; and

                  (xv) to make all  other  determinations  deemed  necessary  or
advisable for administering the Plan.

            (c)  Effect  of  Administrator's   Decision.   The   Administrator's
decisions,  determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

                                      -4-
<PAGE>

         5. Eligibility.  Options may be granted to Service Providers other than
Officers  (except as set forth  herein)  and  Directors.  Officers  shall not be
eligible to receive Options under this Plan; provided, however, that Options may
be  granted  to an  Officer  not  previously  employed  by  the  Company,  as an
inducement  essential to the individual's  entering into an employment  contract
with the Company.

         6.  Limitation.  Neither the Plan nor any Option  shall  confer upon an
Optionee any right with respect to continuing the Optionee's  relationship  as a
Service Provider with the Company,  nor shall they interfere in any way with the
Optionee's  right or the Company's  right to terminate such  relationship at any
time, with or without cause.

         7. Term of Plan.  The Plan shall become  effective upon its adoption by
the  Board.  It shall  continue  in effect  for ten (10)  years,  unless  sooner
terminated under Section 14 of the Plan.

         8.  Term of  Option.  The term of each  Option  shall be  stated in the
Option Agreement.

         9. Option Exercise Price and Consideration.

            (a) Exercise  Price.  The per share exercise price for the Shares to
be  issued  pursuant  to  exercise  of an  Option  shall  be  determined  by the
Administrator.

            (b)  Waiting  Period and  Exercise  Dates.  At the time an Option is
granted,  the Administrator  shall fix the period within which the Option may be
exercised and shall determine any conditions  which must be satisfied before the
Option may be exercised.

            (c) Form of  Consideration.  The  Administrator  shall determine the
acceptable form of consideration for exercising an Option,  including the method
of payment. Such consideration may consist entirely of:

                  (i) cash;

                  (ii) check;

                  (iii) promissory note;

                  (iv)  other  Shares  which (A) in the case of Shares  acquired
upon  exercise of an option,  have been owned by the  Optionee for more than six
months on the date of surrender, and (B) have a Fair Market Value on the date of
surrender  equal to the aggregate  exercise price of the Shares as to which said
Option shall be exercised;

                  (v)  consideration  received by the  Company  under a cashless
exercise program implemented by the Company in connection with the Plan;

                  (vi) a reduction in the amount of any Company liability to the
Optionee,  including any liability attributable to the Optionee's  participation
in any Company-sponsored deferred compensation program or arrangement;

                                      -5-
<PAGE>
                  (vii) such other  consideration  and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws; or

                  (viii) any combination of the foregoing methods of payment.

         10. Exercise of Option.

            (a)  Procedure  for Exercise;  Rights as a  Shareholder.  Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the  Administrator and set
forth in the Option Agreement.  An Option may not be exercised for a fraction of
a Share.

                  An Option shall be deemed exercised when the Company receives:
(i) written or  electronic  notice of exercise  (in  accordance  with the Option
Agreement)  from the person  entitled  to  exercise  the  Option,  and (ii) full
payment  for the Shares  with  respect to which the  Option is  exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator  and permitted by the Option Agreement and the Plan. Shares issued
upon  exercise of an Option  shall be issued in the name of the  Optionee or, if
requested  by the  Optionee,  in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate  entry on the books
of the Company or of a duly authorized transfer agent of the Company),  no right
to vote or receive  dividends or any other rights as a  shareholder  shall exist
with respect to the Optioned Stock,  notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares  promptly  after the
Option is exercised.  No  adjustment  will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued,  except as
provided in Section 13 of the Plan.

                  Exercising  an Option in any manner shall  decrease the number
of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

            (b)  Termination  of  Relationship  as a  Service  Provider.  If  an
Optionee ceases to be a Service  Provider,  other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option  Agreement,  and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified  time in the Option  Agreement,  the Option  shall
remain  exercisable for three (3) months  following the Optionee's  termination.
If, on the date of  termination,  the  Optionee  is not  vested as to his or her
entire Option,  the Shares  covered by the unvested  portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option  within the time  specified  by the  Administrator,  the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

            (c)  Disability of Optionee.  If an Optionee  ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her  Option  within  such  period  of  time  as is  specified  in the  Option
Agreement, to the extent the Option is vested on the date of

                                      -6-
<PAGE>

termination  (but in no  event  later  than the  expiration  of the term of such
Option as set forth in the Option Agreement). In the absence of a specified time
in the Option  Agreement,  the Option shall remain  exercisable  for twelve (12)
months following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by the
unvested portion of the Option shall revert to the Plan. If, after  termination,
the  Optionee  does not  exercise  his or her Option  within the time  specified
herein, the Option shall terminate,  and the Shares covered by such Option shall
revert to the Plan.

            (d) Death of Optionee. If an Optionee dies while a Service Provider,
the Option may be  exercised  within such period of time as is  specified in the
Option  Agreement (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant),  by the  Optionee's  estate or by a
person who acquires the right to exercise the Option by bequest or  inheritance,
but only to the extent  that the  Option is vested on the date of death.  In the
absence of a specified  time in the Option  Agreement,  the Option  shall remain
exercisable for twelve (12) months following the Optionee's termination.  If, at
the time of death,  the  Optionee is not vested as to his or her entire  Option,
the Shares  covered by the  unvested  portion  of the Option  shall  immediately
revert to the Plan. The Option may be exercised by the executor or administrator
of the Optionee's estate or, if none, by the person(s)  entitled to exercise the
Option under the Optionee's will or the laws of descent or distribution.  If the
Option is not so exercised  within the time specified  herein,  the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

            (e) Buyout  Provisions.  The  Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option  previously  granted based on
such terms and conditions as the  Administrator  shall establish and communicate
to the Optionee at the time that such offer is made.

         11.  Non-Transferability of Options. Unless determined otherwise by the
Administrator,  an  Option  may not be sold,  pledged,  assigned,  hypothecated,
transferred,  or disposed of in any manner  other than by will or by the laws of
descent  or  distribution  and may be  exercised,  during  the  lifetime  of the
Optionee,   only  by  the  Optionee.   If  the  Administrator  makes  an  Option
transferable,  such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

         12. Adjustments Upon Changes in Capitalization,  Dissolution, Merger or
Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
shareholders  of the Company,  the number of shares of Common  Stock  covered by
each  outstanding  Option,  and the number of shares of Common  Stock which have
been  authorized for issuance under the Plan but as to which no Options have yet
been  granted  or which  have been  returned  to the Plan upon  cancellation  or
expiration of an Option,  as well as the price per share of Common Stock covered
by each such  outstanding  Option,  shall be  proportionately  adjusted  for any
increase or decrease in the number of issued  shares of Common  Stock  resulting
from a  stock  split,  reverse  stock  split,  stock  dividend,  combination  or
reclassification  of the Common Stock,  or any other increase or decrease in the
number  of  issued  shares  of  Common  Stock   effected   without   receipt  of
consideration  by  the  Company;  provided,  however,  that  conversion  of  any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of  consideration."  Such adjustment shall be made

                                      -7-
<PAGE>

by the Board,  whose  determination in that respect shall be final,  binding and
conclusive.  Except as expressly  provided herein, no issuance by the Company of
shares of stock of any class, or securities  convertible into shares of stock of
any class,  shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

            (b)  Dissolution  or  Liquidation.  In the  event  of  the  proposed
dissolution or liquidation of the Company,  the Administrator  shall notify each
Optionee as soon as  practicable  prior to the  effective  date of such proposed
transaction.  The Administrator in its discretion may provide for an Optionee to
have the right to exercise  his or her Option  until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the  Option  would not  otherwise  be  exercisable.  In  addition,  the
Administrator  may provide that any Company  repurchase option applicable to any
Shares  purchased  upon exercise of an Option shall lapse as to all such Shares,
provided the proposed  dissolution or liquidation takes place at the time and in
the manner contemplated.  To the extent it has not been previously exercised, an
Option will terminate  immediately  prior to the  consummation  of such proposed
action.

            (c) Merger or Asset  Sale.  In the event of a merger of the  Company
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option shall be assumed or an equivalent option
or right  substituted by the successor  corporation or a Parent or Subsidiary of
the successor  corporation.  In the event that the successor corporation refuses
to assume or  substitute  for the Option,  the Optionee  shall fully vest in and
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and  exercisable in lieu of assumption or  substitution  in
the event of a merger or sale of  assets,  the  Administrator  shall  notify the
Optionee in writing or electronically  that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice,  and
the Option shall terminate upon the expiration of such period.  For the purposes
of this  paragraph,  the Option shall be  considered  assumed if,  following the
merger or sale of assets,  the option or right  confers the right to purchase or
receive,  for each Share of Optioned Stock,  immediately  prior to the merger or
sale of assets,  the consideration  (whether stock, cash, or other securities or
property)  received  in the merger or sale of assets by holders of Common  Stock
for each Share held on the  effective  date of the  transaction  (and if holders
were offered a choice of consideration,  the type of consideration chosen by the
holders of a majority of the outstanding  Shares);  provided,  however,  that if
such consideration received in the merger or sale of assets is not solely common
stock of the successor  corporation or its Parent,  the Administrator  may, with
the consent of the successor  corporation,  provide for the  consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock to be
solely  common stock of the  successor  corporation  or its Parent equal in fair
market value to the per share consideration  received by holders of Common Stock
in the merger or sale of assets.

         13.  Date of Grant.  The date of grant of an Option  shall be,  for all
purposes,  the date on which the Administrator makes the determination  granting
such Option,  or such other later date as is  determined  by the  Administrator.
Notice  of the  determination  shall  be  provided  to each  Optionee  within  a
reasonable time after the date of such grant.

                                      -8-

         14. Amendment and Termination of the Plan.

            (a)  Amendment  and  Termination.  The Board may at any time  amend,
alter, suspend or terminate the Plan.

            (b) Effect of Amendment or  Termination.  No amendment,  alteration,
suspension or  termination  of the Plan shall impair the rights of any Optionee,
unless mutually  agreed  otherwise  between the Optionee and the  Administrator,
which  agreement  must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers  granted to it hereunder  with respect to options  granted  under the
Plan prior to the date of such termination.

         15. Conditions Upon Issuance of Shares.

            (a) Legal  Compliance.  Shares  shall not be issued  pursuant to the
exercise of an Option  unless the  exercise of such Option and the  issuance and
delivery of such Shares shall comply with  Applicable  Laws and shall be further
subject  to the  approval  of  counsel  for the  Company  with  respect  to such
compliance.

            (b) Investment Representations. As a condition to the exercise of an
Option the Company may require the person  exercising  such Option to  represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company,  such a representation  is
required.

         16.  Inability  to Obtain  Authority.  The  inability of the Company to
obtain authority from any regulatory body having  jurisdiction,  which authority
is deemed by the  Company's  counsel to be necessary to the lawful  issuance and
sale of any Shares  hereunder,  shall  relieve the Company of any  liability  in
respect of the failure to issue or sell such  Shares as to which such  requisite
authority shall not have been obtained.

         17. Reservation of Shares.  The Company,  during the term of this Plan,
will at all times reserve and keep  available  such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

II.      AGREEMENT

         1. Grant of Option. The Plan Administrator of the Company hereby grants
to the  Optionee  named  in the  Notice  of  Grant  attached  as  Part I of this
Agreement  (the  "Optionee")  an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the  "Exercise  Price"),  subject to the terms and
conditions of the Plan,  which is incorporated  herein by reference.  Subject to
Section  14(b) of the Plan,  in the event of a  conflict  between  the terms and
conditions of the Plan and the terms and  conditions  of this Option  Agreement,
the terms and conditions of the Plan shall prevail.

         2. Exercise of Option.

            (a) Right to Exercise. This Option is exercisable during its term in
accordance  with the  Vesting  Schedule  set out in the  Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

            (b) Method of Exercise. This Option is exercisable by delivery of an
exercise  notice,  in the form  attached as Exhibit A (the  "Exercise  Notice"),
which shall state the election to exercise  the Option,  the number of Shares in
respect of which the Option is being  exercised (the  "Exercised  Shares"),  and
such other  representations  and  agreements  as may be  required by the Company
pursuant to the provisions of the Plan.  The Exercise  Notice shall be completed
by the Optionee  and  delivered  to the  Secretary of the Company.  The Exercise
Notice shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised  Shares.  This Option shall be deemed to be exercised  upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

            No Shares  shall be issued  pursuant to the  exercise of this Option
unless such issuance and exercise  complies with Applicable Laws.  Assuming such
compliance,  for income tax purposes the  Exercised  Shares shall be  considered
transferred  to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

         3. Method of Payment.  Payment of the aggregate Exercise Price shall be
by any of the  following,  or a  combination  thereof,  at the  election  of the
Optionee:

            (a) cash; or

            (b) check; or

            (c) promissory note; or

                                      -2-
<PAGE>

            (d) consideration  received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

            (e)  surrender  of other  Shares  which  (i) in the  case of  Shares
acquired  upon  exercise of an option,  have been owned by the Optionee for more
than six (6) months on the date of surrender,  and (ii) have a Fair Market Value
on the date of surrender equal to the aggregate  Exercise Price of the Exercised
Shares; or

            (f) a  reduction  in the  amount  of any  Company  liability  to the
Optionee,  including any liability attributable to the Optionee's  participation
in any Company-sponsored deferred compensation program or arrangement; or

            (g) such other  consideration and method of payment for the issuance
of Shares to the extent permitted by Applicable Laws.

         4. Non-Transferability of Option. This Option may not be transferred in
any manner  otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this  Option  Agreement  shall be  binding  upon the  executors,
administrators, heirs, successors and assigns of the Optionee.

         5. Term of Option.  This Option may be  exercised  only within the term
set out in the Notice of Grant,  and may be  exercised  during such term only in
accordance with the Plan and the terms of this Option Agreement.

         6. Tax Consequences.  Some of the federal tax consequences  relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE,  AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE  OPTIONEE  SHOULD  CONSULT A TAX ADVISER  BEFORE  EXERCISING  THIS OPTION OR
DISPOSING OF THE SHARES.

            (a)  Exercising the Option.  The Optionee may incur regular  federal
income tax  liability  upon  exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess,  if any, of the Fair Market Value of the Exercised  Shares on the
date of exercise  over their  aggregate  Exercise  Price.  If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her  compensation  or collect from Optionee and pay to the applicable  taxing
authorities an amount in cash equal to a percentage of this compensation  income
at the time of  exercise,  and may  refuse to honor the  exercise  and refuse to
deliver  Shares if such  withholding  amounts are not  delivered  at the time of
exercise.

            (b)  Disposition of Shares.  If the Optionee holds NSO Shares for at
least one year,  any gain realized on  disposition of the Shares will be treated
as long-term capital gain for federal income tax purposes.

the parties with  respect to the subject  matter  hereof and  supersede in their

CAUSE.
