Based on our discussions, we are pleased amend our agreement with you which is dated September 30, 2010 as follows:

1.

Spero Pain Relief Therapy, LLC ("Spero"), and its affiliates will, in selected areas, establish 18 treatment centers utilizing Competitive Technologies, Inc.'s ("CTTC") Calmare^® Pain Therapy Treatment medical device, model MC-5A.  The original agreement was for 14 clinics.  The 4 additional clinics are in [Confidential Information Omitted].

2.

Schedule A-1 is amended to include the zip codes for [Confidential Information Omitted] on Amended Schedule B.  Continued exclusivity is predicated on Spero's purchase or lease of the minimum number of devices indicated on Schedule B.  

3.

The exclusivity conditions, pricing for devices, supplies and training, as well as warranty provisions of the original agreement remain in place.

4.

This agreement is transferable and binding upon any new owners in the event of the change of control or ownership of either CTTC or Spero.

We at Competitive Technologies look forward to a long and mutually beneficial business relationship with Spero Pain Relief Therapy over the coming months and years.

 Sincerely,
