STRATEGIC ALLIANCE AGREEMENT Agreement, dated as of February 27, 1995, between Pixsys, Inc., a Colorado corporation ("Pixsys"), and Surgical Navigation Technologies, Inc., a Delaware corporation ("SNT"). WHEREAS, Pixsys manufactures and sells 3-D optical digitizers which are used in the image guided therapy ("IGT") market (the digitizer sold by Pixsys is referred to herein as the "Pixsys Digitizer"); WHEREAS, SNT has developed and sells an integrated hardware/software system using the Pixsys Digitizer that indicates the position of a surgical probe within a human body on an image of that portion of the body (the "SNT System"); WHEREAS, SNT has been granted the exclusive worldwide right and license to make, use and sell systems utilizing U.S. Patent 5,383,454 ("U.S. Patent") and related foreign and domestic patents which may issue, including divisions, continuations and reissues thereof (collectively with the U.S. Patent, the "SNT Patents"); and WHEREAS, the parties hereto desire to enter into a strategic alliance to more effectively pursue the opportunities in the IGT market. NOW, THEREFORE, the parties hereto, in consideration of the foregoing and their mutual undertakings hereinafter set forth, do hereby agree as follows: 1. PIXSYS DIGITIZER. a. Pixsys agrees to supply the Pixsys Digitizer with any necessary licenses to SNT and SNT agrees to purchase from Pixsys all its requirements for 3-D optical digitizers for the IGT market; provided the Pixsys Digitizer meets mutually agreed upon specifications and delivery schedules and required industry quality standards. b. In connection with the sale of the Pixsys Digitizer, Pixsys will grant SNT any necessary licenses (at a reasonable royalty) to any patents which are hereafter acquired by Pixsys in order for SNT to make, use and sell systems incorporating the Pixsys Digitizer and other Pixsys products to the IGT market (excluding the ENT Market as hereinafter defined). Included with the Pixsys Digitizer will be (i) a nonexclusive, personal and nontransferable license to use the Pixsys software which is part of the Pixsys Digitizer for the purpose of incorporating the Pixsys software into SNT's product and (ii) a right to sublicense the Pixsys software to SNT's customers for use with the Pixsys Digitizer pursuant to Pixsys' standard sublicense agreement. c. Pixsys will only sell the Pixsys Digitizer for IGT applications (other than the ENT Market) to purchasers which, to Pixsys' knowledge, will not use it to infringe any SNT patent. (If SNT disagrees with Pixsys' position, SNT may submit the disagreement to a mutually acceptable third-party arbitrator, knowledgeable as to patents, and if the arbitrator agrees that -2- the purchaser's use is infringing, Pixsys will no longer have the right to sell the Pixsys Digitizer to that purchaser for that use). SNT agrees to discuss a license with GE Medical Systems for the SNT Patents for use with GE Medical Systems' "open" magnetic resonance products and, notwithstanding anything herein to the contrary, Pixsys shall have the right to (i) continue to sell the Pixsys Digitizer to GE Medical Systems during the period of such discussions and for one year thereafter if no license is granted and (ii) to continue to service any digitizer sold to GE Medical Systems, and any other person, that was not sold in violation of this Agreement. Without any implication that the SNT Patents cover applications outside of the IGT market, Pixsys is hereby granted a non-exclusive, world-wide, royalty-free right to make, use and sell its Digitizer (incorporated into systems or alone and with the right to sublicense) in the nonmedical market. 2. SNT SYSTEM. a. SNT hereby (i) agrees to supply Pixsys with its SNT System for incorporation into a Pixsys product for sale in the ear, nose and throat medical market ("ENT Market"), and (ii) grants Pixsys the exclusive worldwide right to sell the SNT System to the ENT Market. The SNT System will be based upon a PC platform with a software user interface that is specifically customized for Pixsys in the ENT market and will meet mutually agreed upon specifications and delivery schedules and required industry quality standards. Pixsys and SNT will mutually agree upon further product differentiation for the ENT Market vis-a-vis -3- the Neuro and Spine markets. The localization/navigation method shall be identified and referred to in all Pixsys marketing literature or journal articles as the "Bucholz Free-Hand-TM-" method and all instruments which are specifically designed by Dr. Bucholz shall be referred to and identified as "Bucholz" instruments. b. In connection with the sale of the SNT System, SNT hereby grants Pixsys the exclusive worldwide right to make, use and sell products and systems covered by the SNT Patents in the ENT Market, including, to the extent necessary, the right to sublicense the SNT Patents to end users in the ENT Market. SNT will also grant to Pixsys any necessary licenses (at a reasonable royalty) to any patents other than the SNT Patents which are hereafter acquired by SNT in order for Pixsys to make, use and sell products incorporating the SNT System and other SNT products to the ENT Market. With the prior approval of SNT, which shall not be unreasonably withheld, Pixsys shall have the right, but not the obligation, to utilize legal and judicial proceedings to protect and enforce the SNT Patents in the ENT Market. Included within SNT's System will be (i) a nonexclusive, personal and nontransferable license to use SNT software which is part of the SNT System for the purpose of incorporating the SNT System into the Pixsys product being sold in the ENT Market and (ii) a right to sublicense the SNT software to Pixsys' customers in the ENT Market for use with the SNT System pursuant to SNT's standard sublicense agreement. -4- c. SNT will not grant any other person or entity a right to make, use or sell products covered by the SNT Patents in the ENT Market nor will it itself make, use or sell products into the ENT Market that will alone, or when combined with other products, be covered by the SNT Patents. SNT may terminate the exclusive rights (in which case Pixsys will retain the non-exclusive rights) granted to Pixsys pursuant to this paragraph 2 at any time within sixty (60) days after the end of any calendar year in the event that Pixsys fails to order the minimum quantity of SNT Systems set forth in Schedule A attached hereto for such year, provided (i) Pixsys is given written notice of termination for such failure from SNT during such sixty (60) day period and (ii) such failure continues for 60 days after Pixsys receives such notice. 3. PATENT REPRESENTATION AND ABANDONMENT. a. SNT represents and warrants that (i) it owns, and has been granted by St. Louis University, the exclusive worldwide right to make, use, and sell systems covered by the U.S. Patent and the SNT Patents, and (ii) it has granted Sofamor Danek Group ("Danek") the exclusive right to sell the SNT System in the Neuro and Spine markets and the right of first refusal for all other medical fields of use except the ENT Market. b. SNT and Pixsys agree to cause Schedule B attached hereto to be executed by the appropriate parties. -5- 4. TERMS OF SALE. a.

Boulder, CO Dear Paul: As you may have heard, Mark Hunter has recently placed, and IGT has confirmed acceptance of, an order for 20 more 5000's for delivery over the course of the Spring/Summer. This is in response to our continuing demand for StealthStations, and trying to stay slightly ahead of the curve. Things continue to go well for us out in the field as well, with minimal recent problems related to the 5000 performance. The SNT Board of Directors recently met, at which time we again reviewed the SNT/IGT history and your and my most recent correspondence. At a formal level, I am now able to express SNT's full agreement with the Strategic Alliance termination proposal contained in your letter to me dated November 29, 1995. My Board has now agreed, the SNT/IGT Strategic Alliance Agreement is terminated and no longer valid. As I suggested to you earlier, I would like to begin discussions to explore an OEM arrangement on digitizer supply from IGT for SNT. I will follow up with Bob Silligman on this topic and hope to begin discussions with you sometime in May when I am next in Colorado. I look forward to talking with you again soon. With best regards, /S/ MARC BUNTAINE Marc Buntaine President and CEO cc: Kurt Smith Bob Silligman Surgical Navigation Technologies, Inc., 337 Fiske Street, Holliston, MA 01746 508.429.6111 FAX 508.429.1767 November 29, 1995 TO: Marc Buntaine, SNT FROM: Paul Ray, IGT Dear Marc: To confirm our conversation this morning, the Strategic Alliance Agreement between Surgical Navigation Technologies and Image Guided Technologies was terminated at our meeting in San Francisco in October and the subsequent actions taken by our respective Boards. The only provisions of the Agreement surviving termination are those noted in the last sentence of paragraph 13a of the Agreement. In reliance on the termination, we withdrew from the business of selling systems to the ENT Market and have returned the exclusive rights for this market to SNT. We would like you to consider a long-term OEM Agreement with us to address our future commercial relationship. This will lock-in your access to our FP5000 digitizer or a more customized proprietary product and allow us to continue our supplier relationship with a valued customer. Under the OEM Agreement, we would of course grant you any necessary licenses (at a reasonable royalty) to any patents which are hereafter acquired by us in order for you to make, use and sell your system incorporating our digitizer. Please get back to me on the OEM Agreement. Best Regards, /S/ PAUL RAY Paul Ray Chief Executive Officer
