Dear Michau:

     I am pleased to offer to you the position of Executive Vice
President-Business Development of a subsidiary (the "Company") of Telecom
Wireless Corporation ("TWC") to be formed for the purpose of acquiring the stock
or assets of Internet service providers and competitive local exchange carriers
and related businesses. If you become employed by TWC or by different subsidiary
of the Company, the term "Company" shall refer to that entity. The terms of your
employment will be as follows:

     1. SERVICES. Your duties and responsibilities will be as assigned to you
from time-to-time by the board of directors of the Company or TWC and/or your
immediate supervisor. You agree to provide these services to the best of your
ability in a prompt, efficient and professional manner. Unless otherwise agreed
in writing by the board of directors of TWC, you agree to devote your full time,
attention and energies to the business of the Company.

     2. BASE SALARY AND BONUSES. Your annual base salary shall be $135,000,
subject to normal and customary deductions and withholdings, payable in
installments according to the Company's regular payroll schedule. Your job
performance will be evaluated by your supervisor and/or the Company's board of
directors and reviewed with you annually at about the end of each year and merit
raises and/or bonuses may be awarded in the sole discretion of the board of
directors of the Company.

     3. HIRE DATE. Your hire date shall be February 26, 2000.

     4. STOCK OPTIONS AND STOCK BONUS. Subject to applicable legal requirements
and the terms of TWC's 1999 Stock Option and Restricted Stock Plan, TWC agrees
to grant to you non-qualified options for the purchase of 450,000 shares of
TWC's common stock, par value $.001 per share, which will vest and become
exercisable in equal installments on each of the first three annual anniversary
dates of your hire date by the Company. Additionally, upon commencement of your
employment, TWC agrees to grant to you 10,500 shares of its common stock as a
signing bonus. Unless registered, the shares of common stock issuable upon
exercise of the options and the bonus shares will be restricted under federal
and applicable state securities laws and subject to substantial restrictions on
transfer. You represent and warrant to TWC that you are a bona fide resident of
the state of New York and that you are an accredited investor as that term is
defined in Rule 215 under the Securities Act of 1933 as indicated in Exhibit A
attached hereto and by this

the bonus shares and the shares underlying your stock options for public sale on
Form S-8 at the earliest practicable time.

     5. PERFORMANCE BONUS. You shall also be entitled to receive bonuses based
on performance upon such terms and in such amounts as shall be defined and
determined by the board of directors of the Company based upon the net increase
in revenues, profitability and cash flow of businesses acquired by the Company
and approved by the mergers and acquisitions committee appointed by the board of
directors of TWC.

     6. EMPLOYMENT AT WILL. Your employment by the Company pursuant to this
letter or otherwise is "at will" and is for no specific period of time.
Accordingly, either you or the Company may terminate your employment by the
Company for any reason and at any time on not less than ten days written notice.
Upon termination of your employment by either of us, the Company may immediately
relieve you of all duties. In the event, however, your employment should be
terminated by the Company without cause at any time prior to the third
anniversary of your hire date, you shall be entitled to receive severance
compensation based on your base salary as of the termination date, but not to
exceed your base salary as of the termination date for the remainder of the
three-year period following your hire date, as follows:

to cure, and you terminate your employment by the Company not less than five
business days after expiration of the cure period due solely to the Company's
failure to cure.

all or a portion of the premiums for you and your family members for medical and
dental insurance. In the event your family members are not eligible to be
included in the Company's medical and dental plans at your hire date due to the
terms of such plans, the Company shall reimburse you for COBRA medical insurance
premiums paid by you until such time as your family members become eligible to
participate in such plans.

Company or other entities, and the prohibition against tipping others about any
such material non-public information.

     10. CONFIDENTIALITY AGREEMENT. You agree, both during and after your
employment by the Company, not to reveal confidential or proprietary information
or trade secrets ("Confidential Information") owned, used by or in the

Information, you agree that the Company shall be entitled, without notice to
you, to an injunction restraining you from disclosing Confidential Information
or from rendering services to any entity to which Confidential Information has
been or is threatened to be disclosed. This right to an injunction shall not be
the exclusive remedy of the Company which may also seek other remedies including
damages.

     11. ARBITRATION. Except as specifically provided herein to the contrary, in
the event of any differences, claims or disputed matters relating to or arising
from your employment by the Company, we agree to submit such matters to

                          TELECOM WIRELESS CORPORATION

                       NONQUALIFIED STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT, hereinafter referred to as the "Option" or the
"Agreement," made on the 26th day of February, 2000, between TELECOM WIRELESS
CORPORATION, a Utah corporation (the "Company"), and PAUL HART ("the Optionee"),
residing at 6 Walt Whitman Trail, Morristown, New Jersey 07960.

     The Company hereby grants an option (the "Option") for the purchase of
750,000 shares of common stock (the "Option Shares") of the Company, $.001 par
value per share ("Common Stock"), to the Optionee at the price and in all
respects subject to the terms, definitions and provisions of this Agreement. The
Option is NOT granted pursuant to the terms of the TELECOM WIRELESS CORPORATION
1999 Stock Option Plan (the "Plan") and shall not reduce the shares of Common
Stock available for issuance under the Plan.

     1. DESIGNATION OF OPTION. The option granted hereby is a Nonqualified
Option which is not intended to qualify as an incentive stock option within the
meaning of Section 422 of the Internal Revenue Code.

     2. OPTION EXERCISE PRICE. The option exercise price is $6.99 for each
share.

     3. OPTION PERIOD. The option period during which this Option may be
exercised shall expire at 12:00 o'clock p.m., Denver time, on the 26th day of
February, 2005.

     4. EXERCISE OF OPTION.

        4.1 STANDARD VESTING. The number of shares optioned shall be divided as
nearly as possible into three (3) equal installments. The first installment
shall accrue and the Option shall be exercisable with respect to the shares
included therein on the date which is one year after the grant of the Option.
Each succeeding installment shall accrue and the Option shall be exercisable
with respect to the shares included therein on each yearly anniversary date
thereafter. An option may be exercised when installments accrue and at any time
thereafter within the option period set forth in Section 3 above with respect to
all or a part of the shares covered by such accrued installments, subject,
however, to further provisions of this Section 4.

        4.2 DEFERRED VESTING. Notwithstanding subsection 4.1 herein, in the
event Optionee was a member of the Board of Directors of the Company at the time
the grant of this Option was approved, this Option shall not be exercisable
until the grant of this Option shall have been ratified, confirmed and approved
by the shareholders of the Company in the manner required by law.

        4.3 ACCELERATED VESTING. Except as provided to the contrary in
subsection 4.2 herein, all Options shall immediately vest and become exercisable
in full upon a Change in Control, even if all or any portion of the Options
shall not have vested in accordance with subsection 4.1 herein. "Change in
Control" shall mean (i) any transaction or series of transactions in which any
person or group of persons, other than Dr. James C. Roberts, directly or
indirectly (a) becomes the beneficial owner of outstanding securities of the
Company having 30% or more of the power to vote upon the election of the
Company's directors or (b) acquires 50% or more of the Company's assets, or (ii)
the occurrence of any transaction or event in connection with which all or
substantially all of the voting securities of the Company are exchanged for,
converted into, acquired for or constitute solely the right to receive cash,
securities, property or other

<PAGE>

assets, or (iii) the conveyance, sale, lease, assignment, transfer or other
disposal of all or substantially all of the Company's property, business or
assets otherwise than in the ordinary course of business.

        4.4 RIGHT TO EXERCISE. The Option shall be exercisable only during the
option period by the Optionee while the Optionee is in "continuous employment
with the Company;" provided, however, if the Optionee's employment is terminated
by Optionee for cause or by the Company without cause, the Optionee shall have a
period of three (3) months from the date his employment terminates in which to
exercise the Option to the extent the Option was exercisable at the time of
termination, but in no event later than the expiration of the option period. If
the Optionee should die during this three (3) month period, the Option may be
exercised by the person or persons to whom the rights under the Option passed by
will or the laws of descent and distribution to the same extent and during the
same period the Optionee could have exercised the Option had he not died. In the
event the Optionee should terminate his employment by the Company without cause
or the Company should terminate his employment with cause, then all unexercised
Options granted to Optionee shall be forfeited and canceled effective upon such
termination.

            4.4.1 If the Optionee should die or become permanently and totally
disabled while employed by the Company, the Option or unexercised portion
thereof, to the extent exercisable at the time of his death or disability, may
be exercised by Optionee, his conservator or legal guardian or by the person or
persons to whom his rights under the Option passed by will or the laws of
descent and distribution not later than twelve months after the Optionee's death
or not later than twelve months after the Optionee's disability, but in no event
later than the expiration of the option period.

            4.4.2 The Option granted shall be void if not exercised during the
option period. Except as otherwise provided, the option period shall terminate
in the event the Optionee ceases to be an Employee of the Company (including any
Subsidiary Corporation) if that date is earlier than the term of the Option.

            4.4.3 For the purposes of the foregoing, "continuous employment
with the Company" shall mean the absence of any interruption or termination of
employment by the Company and/or by a corporation in which the Company owns
capital stock having a majority of the voting power with respect to the election
of directors ("Subsidiary Corporation"). Continuous employment shall not be
considered interrupted in the case of leave of absence approved by the Company
or the Subsidiary Corporation.

        4.5 METHOD OF EXERCISE. This Option shall be exercisable by a written
notice which shall:

            4.5.1 State the election to exercise the Option, the number of
shares in respect of which it is being exercised (which must be in multiples of
one hundred (100) shares), the person in whose name the stock certificate or
certificates for such shares of Common Stock is to be registered, his address
and Social Security number (or if more than one, the names, addresses and Social
Security numbers of such persons);

            4.5.2 Contain such representations and agreement as to the holder's
investment intent with respect to such shares of Common Stock as may be

            4.5.3 Be signed by the person or persons entitled to exercise the
Option and, if the Option is being exercised by any person or persons other than
the Optionee, be accompanied by proof, satisfactory to counsel for the Company,
of the right of such person or persons to exercise the Option.

            4.5.4 Payment of the purchase price of any shares with respect to
which the Option is being exercised shall be by cash or certified check,
previously acquired shares having a fair market value equal to the option price
or previously acquired shares having a fair market value less than the option
price, plus cash or certified check, and shall be delivered with the notice of
exercise. The certificate or certificates for shares of Common Stock as to which
the Option shall be exercised shall be registered in the name of the person or
persons exercising the Option.

        4.6 RESTRICTIONS ON EXERCISE. As a condition to his exercise of this
Option, the Company may require the person exercising this Option to make any

     5. NONTRANSFERABILITY OF OPTION. This Option may not be transferred in any
manner and may be exercised during the lifetime of the Optionee only by him and
after his death by the person or persons to whom his rights under the Option
passed by will or the laws of descent and distribution.

     6. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. Whenever a stock split,
stock dividend or other relevant change in capitalization occurs, the number of
shares that can thereafter be purchased, and the option price per share, under
each Option that has been granted and not exercised, and every number of shares
used in determining whether a particular option is grantable thereafter, shall
be appropriately adjusted.

delivered in person or by certified mail to the proper address. Each notice
shall be deemed to have been given on the date it is received. Each notice to
the Company shall be addressed to it at its principal office, attention of the
Secretary. Each Optionee or other person or persons then entitled to exercise
the Option shall be addressed to the Optionee or such other person or persons at
the Optionee's address set forth in the heading of this Agreement. Anyone to
whom a notice may be given under this Agreement may designate a new address by
notice to that effect.

     8. BENEFITS OF AGREEMENT. This Agreement shall inure to the benefit of and
be binding upon each successor of the Company. All obligations imposed upon the
Optionee and all rights granted to the Company under this Agreement shall be
binding upon the Optionee's heirs, legal representatives and successors. This
Agreement shall be the sole and exclusive source of any and all rights which the
Optionee, his heirs, legal representatives, or successors may have in respect to
the Option or Common Stock granted or issued thereunder, whether to himself or
to any other person.

     9. RESOLUTION OF DISPUTES. Any dispute or disagreement which should arise
under, or as a result of, or in any way relate to, the interpretation,
construction or applicability of this Agreement will be determined by the Board
of Directors of the Company. Any determination made hereunder shall be final,
binding, and conclusive for all purposes.

     IN WITNESS WHEREOF, the Company and the Optionee have caused this Agreement
to be executed as of the day, month and year first above written.
