         RE:      Agreement to  Terminate  Letter of Intent  Dated July 25, 2005
                  Between  IPEX,  Inc. and Vinculum Communications, Inc.

Dear Mr. Goodwin:

      As per our recent discussions, this letter (this "Termination Agreement")
shall constitute the agreement among IPEX, Inc., a Nevada corporation ("IPEX"),
and Vinculum Communications, Inc., a Delaware corporation ("Vinculum"), to
terminate that certain Letter of Intent (the "LOI") dated July 25, 2005 for IPEX
to acquire (the "Proposed Acquisition") all of the issued and outstanding shares
of stock of Vinculum. The following sets forth the terms mutually agreed upon
between IPEX and Vinculum in connection therewith.

      1. IPEX and Vinculum hereby agree to terminate the LOI and all
transactions contemplated pursuant to the LOI.

      2. Vinculum hereby acknowledges that to date IPEX has advanced $75,000 to
Vinculum as a pre-pay deposit for traffic.

      3. IPEX hereby agrees that, notwithstanding the requirement of Section 3
of the LOI, IPEX shall pay Vinculum the sum of $55,000 which represents
reimbursement of expenses incurred by Vinculum in connection with the
negotiation of and due diligence associated with the LOI and the Proposed
Acquisition. Such $55,000 payment shall be deducted from the $75,000 pre-payment
made by IPEX to Vinculum as described in Section 2 above. Vinculum hereby
acknowledges that, as of the date hereof, Vinculum owes IPEX the outstanding
principal sum of $20,000, which will be offset against any monies owed to
Vinculum by IPEX and which shall be repayable by Vinculum without interest upon
demand by IPEX.
