Baltimore, Maryland 21215

Attention: Lee D. Rudow, President

Gentlemen:

         This letter sets forth the agreement between the undersigned, Dennis W.
Stone ("Holder"), and Davis Instruments, LLC, a Maryland limited liability
company ("Davis"). This letter (the "Proxy") is entered into concurrently with a
letter agreement of even date herewith (the "Letter of Intent") by and between
Davis and Inotek Technologies Corp., a Delaware corporation ("Inotek").
Capitalized terms used but not defined herein shall have the meanings given to
such terms in the Letter of Intent, unless the context otherwise requires.

         Davis desires to obtain Holder's proxy to vote all of the shares of
common stock of Inotek which he has the power to vote, in consideration of the
time, effort, money and resources which Davis has expended and will expend in
furtherance of the transactions contemplated by the Letter of Intent. Holder
acknowledges that Davis agreement to the terms and provisions of the Letter of
Intent is conditioned on the execution of this Proxy by Holder and that, in the
absence of this Proxy, Davis would not execute the Letter of Intent. Holder is
executing this Proxy in order to induce Davis to enter into the Letter of Intent
and to obtain the benefits of the Letter of Intent and the transactions
contemplated thereby.

         Holder represents and warrants to Davis that (i) he has the exclusive
power to vote all of the shares of common stock of Inotek identified on Exhibit
A-1 hereto; and (ii) this Proxy is a legal, valid and binding obligation of
Holder, enforceable against him in accordance with its terms. Holder hereby
appoints Lee D. Rudow and Mitchell J. Paige, and each of them individually, as
proxies, attorneys and agents of Holder, with full power of substitution, (1) to
vote in the name and on behalf of Holder for the approval of the Merger, and
against any other proposal relating to any acquisition or change in control of
Inotek, at all meetings of stockholders (including all adjournments thereof),
and (2) to exercise, in the name of Holder, the power to consent to actions of
the stockholders of Inotek in approving the Merger and against any other
proposal relating to any acquisition or change in control of Inotek, with all
the powers Holder would possess with respect to such actions.

         The proxy granted herein is irrevocable from the date hereof until the
earlier to occur of the effective time of the Merger or a termination of the
Letter of Intent in accordance with its terms. For so long as this Proxy is in
effect, Holder will not sell, transfer, assign or otherwise dispose of any
shares of stock of Inotek, nor will Holder grant any proxy or other voting
rights to any person other than Davis.

         Inotek represents to Davis that it has no reason to believe that any
provision of this Proxy is unenforceable or that any person other than Holder
has any right to vote the shares of stock of Inotek to which this Proxy relates.
Inotek is executing this Proxy for the purpose of evidencing (1) its knowledge
of the terms hereof and (2) its agreement that it will recognize the validity of
the proxy granted herein in connection with any vote or consent of stockholders
during the term hereof.

         This Proxy may not be amended except by a written instrument executed
by all of the parties hereto. This Proxy may be executed in two or more
counterparts, each of which shall be deemed an original and all of which shall
be deemed one and the same instrument.

         IN WITNESS WHEREOF, the parties have duly executed this Proxy as of the
day and year first above written.
