Consulting Agreement (this "Agreement") made this 21st day of January 2003
between Wire One Technologies, Inc., a Delaware corporation having its principal
office at 225 Long Avenue, Hillside, New Jersey 07205 (hereinafter "Wire One"),
and Jonathan Birkhahn, 258 Riverside Drive, New York, New York 10025
(hereinafter "Consultant").

Whereas, Consultant is currently employed by Wire One as Executive Vice
President Business Affairs and General Counsel under an agreement dated November
30, 2000, as amended July 30, 2002 (collectively, the "Employment Agreement");

Whereas, Consultant and Wire One have determined it to be in their mutual best
interests to terminate the term of the Employment Agreement, simultaneous with
the commencement of Consultant's engagement as a consultant.

Now Therefore, in consideration of their mutual promises made herein, and for
other good and valuable consideration, the parties hereby agree as follows:

1.   Termination of Term of Employment Agreement; Commencement of Consultancy
     Term. (a) The term of the Employment Agreement (including in association
     therewith Consultant's appointment as Wire One' corporate secretary) shall
     terminate on January 31, 2003 (the "Employment Agreement Termination
     Date"). Consultant acknowledges that he shall not, either upon or otherwise
     by virtue of such termination, become entitled to receive any severance
     compensation of any nature whatsoever. (b) The term of Consultant's
     services under this Agreement (the "Consultancy Term") shall commence upon
     the day following the Employment Agreement Termination Date and shall,
     subject to Paragraph 5 below, terminate on November 30, 2003.

2.   Services. Consultant shall assist Wire One's management and outside legal
     counsel in the administration of Wire One's legal and business affairs,
     including without limitation participation in (a) the preparation and
     drafting of commercial contracts, (b) transactions involving the
     acquisition or disposition of assets, (c) reporting and other compliance
     under the securities laws, (d) personnel and other labor matters and (e)
     management of litigation. Consultant shall be available to Wire One
     approximately 20 hours per week for his performance of services under this
     Agreement and shall devote first priority to his responsibilities to Wire
     One among all of his professional responsibilities.

3.   Compensation. As compensation for Consultant's services under this
     Agreement, Wire One shall (a) pay Consultant a cash fee, with respect to
     each month of the Consultancy Term, in the amount of $11,500 per month (the
     "Cash Fee"), payable on the fifteenth day of each such month, and (b)
     permit Consultant to retain the stock options granted to his during his
     employment by Wire One, provided that the vesting of such stock options
     shall (to the extent based solely upon Consultant's continuing engagement
     hereunder) cease upon any termination of the Consultancy Term in accordance
     with Paragraph 5 below (it being understood that such vesting shall
     continue to the extent based upon Consultant's continuing service as a
     member of the Board of Directors of Wire One). Consultant's rights as an
     optionee shall continue to be governed by the terms of the associated stock
     option agreements currently in effect and the 2000 Stock Incentive Plan.
     Wire One shall, in addition to Consultant's compensation, reimburse
     Consultant for any reasonable expenses incurred by Consultant in the
     performance of his duties under this agreement, upon submission of evidence
     thereof reasonably satisfactory to Wire One.

4.   Information; Work Product. From time to time as requested by Consultant,
     Wire One shall furnish to Consultant any information that is reasonably
     required to enable Consultant to perform his duties under this agreement.
     Consultant shall not disclose any confidential information furnished to his
     by Wire One unless, and then only to the extent that, such disclosure is
     legally required. Any compilation of data, work product, work of authorship
     and other materials created or produced by Consultant within the scope of
     his duties under this agreement shall be the sole and exclusive property of
     Wire One.

5.   Consultant's Other Endeavors. Wire One acknowledges that Consultant plans
     to pursue employment or consultancy engagements by parties other than Wire
     One ("Other Endeavors") and that Consultant shall (subject to the final
     sentence of Paragraph 2 above) have the unrestricted right to pursue Other
     Endeavors, whether or not such Other Endeavor results in a conflict of
     interest with the interests of Wire One (a "Conflict"). If Consultant
     secures any Other Endeavor (of which Consultant shall promptly notify Wire
     One, for purposes of both this Paragraph 5 and of Paragraph 1 (b) above),
     (a) Consultant shall have the right to terminate the Consultancy Term
     effective upon at least ten days' prior written notice to Wire One (but not
     earlier than February 28, 2003) and (b) if Wire One reasonably determines
     that such Other Endeavor results in a Conflict, Wire One shall have the
     right to terminate the Consultancy Term effective upon at least ten days'
     prior written notice to Consultant. In the case of any such termination,
     the Cash Fee for the calendar month within which such termination becomes
     effective shall be adjusted pro rata to reflect the resulting partial
     calendar month of the Consultancy Term (it being understood that, if
     Consultant has already received payment of the full Cash Fee for such
     calendar month, Consultant shall refund to Wire One a pro rata portion
     thereof corresponding to the portion of such month remaining following the
     effective date of such termination).

6.   Miscellaneous. This agreement is made in the State of New Jersey and shall
     be governed by New Jersey law. This agreement constitutes the entire
     agreement, and shall supersede any prior or contemporaneous agreement, oral
     or written, between the parties hereto regarding Consultant's services to
     Wire One as an employee or consultant following the Employment Agreement
     Termination Date (it being understood that the provisions of the Employment
     Agreement that survive the termination of the "Employment Period"
     thereunder shall remain in full force and effect) and may not be modified
     or amended except by a written document signed by the party against whom
     enforcement is sought. The relationship of Consultant to Wire One is solely

     that of independent contractor and nothing herein shall be deemed to place
     the parties in any other or different relationship, including but not
     limited to that of employer-employee, principal-agent, or as partners in a
     joint venture. This agreement may be signed in more than one counterpart,
     in which case each counterpart shall constitute an original of this
     agreement.


IN WITNESS WHEREOF, the parties have signed this agreement as of the day and
year first above written.
