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:

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.

all provisions of the Company's employee manual when prepared and as thereafter

while in the possession of material non-public information relating to the
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
possession of the Company or any subsidiary or affiliate of the Company, to any
individual or entity. Should you reveal or threaten to reveal Confidential
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
