EXHIBIT 10 UNIVERSITY OF WASHINGTON SEATTLE, WASHINGTON 98105-6613 Office of Research Grant and Contract Services March 27, 1998 Richard Raisig Chief Financial Officer Microvision, Inc. 2203 Airport Way South, Suite 100 Seattle, Washington 98134 Subject: No Cost Time Extension of the Research Agreement Between the University of Washington and Microvision Dear Mr. Raisig: The Research Agreement between the University of Washington and Microvision was extended by mutual agreement for six months through March 31, 1998 by our letter agreement of September 30, 1997. We now anticipate that approximately $105,000 will remain as the unencumbered balance on March 31, 1998, and Dr. Furness has requested that the University and Microvision extend the Project through December 31, 1998. Therefore, on behalf of the University and at Dr. Furness' request, I am formally requesting an extension of the Research Agreement through December 31, 1998. Generally, the additional work to be done during this extension period will fall within the framework of the original research plan attached to the Research Agreement and will be a continuation of the work already done on the original project, but otherwise I leave to Dr. Furness the details of the work to be done. I am requesting that you approve our request by signing this letter. Please send your approval to my attention. Thank you. Sincerely, DONALD W.
