                       FIRST AMENDMENT TO LEASE AGREEMENT

      This First Amendment to Lease Agreement (this "Amendment") is made and

whose principal place of business and address is Suite 1100, 100 East
RiverCenter Boulevard, Covington, Kentucky 41011 (hereinafter "Landlord") and
Wire One Technologies, Inc., a Delaware corporation (hereinafter "Tenant").

      WHEREAS, original Landlord and Tenant entered into that certain Lease
Agreement ( the "Lease Agreement") dated December 21, 2001 whereby original
Landlord leased and demised to the Tenant 49,277 square feet of space in a
building located at the intersection of Maue Road, Lyons Road and Bauer Road, in
Miamisburg, Montgomery County, Ohio (as defined herein and in the Lease
Agreement, the "Leased Premises"); and

      WHEREAS, Key Property Development Corporation was incorrectly listed as
the owner of the Building and above referenced property wherein the Leased
Premises are located; and

      WHEREAS, title to the estate and interest in the land and Building of
which the Leased Premises is a part is vested in Maue-Lyons Associates, Ltd., an
Ohio limited liability company by virtue of a deed dated December 12, 1995 and
recorded December 22, 1995 in Deed Microfiche 95-0783-B09, Montgomery County,
Ohio Recorder's Office records; and

      WHEREAS, the parties hereto desire to amend the original Lease for the
purpose of clarifying that Maue-Lyons Associates, Ltd. is the fee simple owner
of the Building and property wherein the Leased Premises are located and as such
is the proper Landlord pursuant to the Lease; and

      WHEREAS, the parties hereto further desire to amend the original Lease for
the purpose of clarifying the commencement date of the Lease term and the
termination date of the Lease term.

      NOW, THEREFORE, in consideration of the mutual covenants contained herein
and in the Lease and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Original Landlord, Landlord and
Tenant hereby agree that the Lease Agreement is hereby amended as follows:

1).   Substitution of Landlord. The original Lease is hereby amended to provide
      that Maue-Lyons Associates, Ltd., an Ohio limited liability company, is
      hereby


                                       1


      substituted for and in place of Key Property Development Corporation
      throughout the entire original Lease as "Landlord". Wherever the term
      "Landlord" shall appear in the original Lease or this Amendment, such term
      shall be deemed to mean and be Maue-Lyons Associates, Ltd., an Ohio
      limited liability company;

2).   Withdrawal of Key Property Development Corporation. Key Property
      Development Corporation is hereby removed as a party to the Lease, and
      from and after the date of this Amendment shall have no further rights or
      obligations with respect to the Lease;

3).   Commencement Date and Termination Date; Substitution of Exhibit "D". The
      parties hereto agree that the Commencement Date of the Lease is February
      1, 2002 and the Expiration Date is the 31st day of January, 2008. The
      parties hereto further agree that the "First Amended Exhibit D" attached
      hereto and made a part hereof shall be and is hereby substituted for
      Exhibit "D" as attached to the original Lease.

4).   Miscellaneous. The parties hereto agree that, except as modified and
      amended herein, all other terms, covenants and conditions of the Lease
      shall remain and be in full force and effect; provided, however, that the
      provisions contained in this First Amendment to Lease Agreement shall
      control to the extent that these provisions are in addition to or in
      conflict with any provision(s) of the Lease. Wherever a defined or
      capitalized term is used or contained herein, such term, unless otherwise
      defined herein, shall have the same meaning as given to such term(s) as
      set forth and defined in the original Lease Agreement.

      IN WITNESS WHEREOF, the parties hereto have executed this First Amendment
to Lease Agreement as of the day and year first written above herein.
