                          AGREEMENT AND PLAN OF MERGER

     This Agreement and Plan of Merger, dated as of May 15, 2001, is by and
among Davis Instruments, a Maryland limited liability company ("Davis"), INOTEK
Technologies Corp., a Delaware corporation ("Inotek") and Neal E. Young, David
L. White and Dennis W. Stone (the "Principal Stockholders"). This Agreement and
Plan of Merger is hereinafter referred to as the "Agreement."

     In consideration of the mutual representations, warranties, agreements and
covenants contained herein, Davis, Inotek and the Principal Stockholders hereby
agree as follows:

                                   ARTICLE I

               TERMS OF THE MERGER & CLOSING; EXCHANGE OF SHARES

     SECTION 1.01. The Merger.  Davis will organize an interim subsidiary
("Newco") and, subject to the satisfaction or waiver of the conditions set forth
in Article VI of this Agreement, Davis will cause Newco to merge with and into
Inotek (the "Merger") pursuant to applicable corporate law ("Corporate Law"), in
a merger in which Inotek will be the surviving corporation.

     SECTION 1.02. Effects of the Merger.  (a) The Merger shall have all of the
effects provided by Corporate Law and this Agreement, and the separate corporate
existence of Newco shall cease on consummation of the Merger and be combined in
Inotek.

     (b) The Certificate of Incorporation of Inotek from and after the Effective
Time shall be amended as set forth on Exhibit A attached hereto.

     (c) The Bylaws of Inotek from and after the Effective Time shall be the
same as the Bylaws of Newco immediately prior to the Effective Time, except for
the corporate name which shall be "INOTEK Technologies Corp."

     (d) The directors and officers of Newco immediately prior to the Effective
Time shall, without the necessity of any further corporate action, become the
directors and officers of Inotek from and after the Effective Time.

     SECTION 1.03. Conversion of Shares.  (a) At the Effective Time, subject to
the terms of this Agreement and the Escrow Agreement (as defined in Section
1.06(b)(iii), each share of common stock, $0.01 par value, of Inotek ("Inotek
Common") issued and outstanding immediately prior to the Effective Time shall be
converted into the right to receive $0.65 (the "Common Share Merger Price");
provided, however, that shares of Inotek Common held in the treasury of Inotek
or by any direct or indirect subsidiary of Inotek immediately prior to the
Effective Time shall be canceled.

     (b) The stock transfer books of Inotek shall be closed, and no share
transfers will be permitted after the Effective Time. At the Effective Time, by
virtue of the Merger and without any action on the part of the holders thereof,
all of the shares of Inotek Common shall cease to be outstanding and be
canceled.

     (c) If holders of Inotek Common are entitled to require appraisal of their
shares under applicable Corporate Law, shares held by a dissenting holder who
has perfected the right to obtain an appraisal of his shares shall not be
converted as described in this Section 1.03, but from and after the Effective
Time shall represent only the right to receive such consideration as may be
determined pursuant to applicable Corporate Law; provided, however, that each
share of Inotek Common outstanding immediately prior to the Effective Time and
held by a dissenting holder who after the Effective Time shall withdraw his
demand for appraisal or lose his right of appraisal shall thereafter have only
such rights as are provided under applicable Corporate Law.

     (d) Any options to purchase shares of Inotek Common ("Inotek Options")
which are not exercised prior to the Effective Time shall be canceled at the
Effective Time.

     (e) At the Effective Time, the outstanding shares of common stock of Newco
shall be converted into an equal number of shares of Inotek Common, so that
immediately following the effective time of the Merger,
   5

the number of outstanding shares of Inotek Common shall be equal to the number
of outstanding shares of common stock of Newco immediately prior to the Merger.

     SECTION 1.04. The Closing.  The closing of the Merger (the "Closing") shall
take place at the offices of legal counsel for Davis or at such other location
as is mutually agreeable to the parties hereto at 10:00 a.m. local time on the
Closing Date described in Section 1.05 of this Agreement.

     SECTION 1.05. The Closing Date.  The Closing shall take place at a date and
time designated by Davis not later than five (5) business days following the
satisfaction or waiver of the conditions set forth in Sections 6.01 and 6.02, or
on such other date as Davis and Inotek may agree (the "Closing Date"). The
Merger shall be effective at the time specified in Corporate Law (the "Effective
Time").

     SECTION 1.06. Actions At Closing.  (a) At the Closing, Inotek shall deliver
to Davis:

          (i) certified copies of the Certificate of Incorporation and Bylaws of
     Inotek;

     and President of Inotek stating that (A) each of the representations and
     warranties contained in Article II is true and correct in all material
     respects at the time of the Closing with the same force and effect as if
     such representations and warranties had been made at the Closing, and (B)
     all of the conditions set forth in Section 6.01 have been satisfied or
     waived as provided therein;

          (iii) a certified copy of resolutions of the Board of Directors of
     Inotek and of the stockholders of Inotek, establishing the requisite
     approvals under applicable Corporate Law of this Agreement, the Merger and
     the other transactions contemplated hereby;

          (iv) the complete minute book of Inotek and access to complete stock
     transfer records reflecting transfers of Inotek Common prior to the
     Effective Time; and

          (v) a certificate of Inotek's transfer agent, in form and substance
     reasonably satisfactory to Davis, reflecting the capitalization of Inotek
     as of the day preceding the Closing Date.

     (b) At the Closing, Davis shall deliver to Inotek:

          (i) a certificate signed by the President of Davis stating that (A)
     each of the representations and warranties contained in Article III is true
     and correct in all material respects at the time of the Closing with the
     same force and effect as if such representations and warranties had been
     made at the Closing, and (B) all of the conditions set forth in Section
     6.02 have been satisfied or waived as provided therein;

          (ii) a certified copy of resolutions of the Board of Directors of
     Davis and Newco and of the stockholder of Newco, establishing the requisite
     approvals under applicable Corporate Law of this Agreement, the Merger and
     the other transactions contemplated hereby; and

     terms of an Escrow Agreement of even date herewith by and among Davis,
     Inotek and the Principal Stockholders (the "Escrow Agreement").

     SECTION 1.07. Exchange Procedures; Surrender of Certificates.  As soon as
reasonably practicable after the Effective Time, Davis shall mail to each record
holder of shares of Inotek Common a letter of transmittal in form reasonably
satisfactory to Inotek (which shall specify that delivery shall be effected, and
risk of loss and title to certificates shall pass, only upon proper delivery of
the certificates to Davis and shall be in such form and have such other
provisions as Davis may reasonably specify) and instructions for use in
effecting the surrender of certificates, and, after deducting the amount to be
deposited in an escrow account pursuant to Section 1.06(b)(iii), Davis shall
promptly pay the appropriate consideration to former holders of Inotek Common
who make proper delivery of certificates or comply with Davis's reasonable
instructions and requirements with respect to any certificate that has been lost
or stolen.

     (c) Except as disclosed in Sections 2.01(c) and 2.12(c) of the Disclosure
Schedule, Inotek does not maintain, contribute to or participate in or have any
liability under any employee benefit plans, as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or any
nonqualified employee benefit plans or deferred compensation, bonus, stock or
incentive plans, or other employee benefit or fringe benefit programs for the
benefit of former or current employees (collectively, the "Employee Plans"). No
present or former employee of Inotek has been charged with breaching nor has
breached a fiduciary duty under any Employee Plan. Inotek does not participate
in, nor has it in the past five years participated in, nor has it any present or
future obligation or liability under, any multiemployer plan (as defined at

     (d) All liabilities of the Employee Plans have been funded on the basis of
consistent methods in accordance with sound actuarial assumptions and practices,
and no Employee Plan, at the end of any plan year, or at February 28, 2001 had
an accumulated funding deficiency. No actuarial assumptions have been changed
since the last written report of actuaries on the Employee Plans. All insurance
premiums (including premiums to the Pension Benefit Guaranty Corporation) have
been paid in full, subject only to normal retrospective adjustments in the
ordinary course. Except as reflected in the Inotek Financial Statements, Inotek
has no contingent or actual liabilities under Title IV of ERISA. No accumulated
funding deficiency (within the meaning of Section 302 of ERISA or Section 412 of
the Internal Revenue Code of 1986, as amended (the "Code")) has been incurred
with respect to any Employee Plan, whether or not waived. No reportable event
(as defined in Section 4043 of ERISA) has occurred with respect to any Employee
Plan as to which a notice would be required to be filed with the Pension Benefit
Guaranty Corporation. No claim is pending, threatened or imminent with respect
to any Employee Plan (other than a routine claim for benefits for which plan
administrative review procedures have not been exhausted) for which Inotek would
be liable, except as is reflected in the Inotek Financial Statements. Inotek has
no liability for excise taxes under Sections 4971, 4975, 4976, 4977, 4979 or
4980B of the Code or for a fine under Section 502 of ERISA with respect to any
Employee Plan. All Employee Plans have in all material respects been operated,
administered and maintained in accordance with the terms thereof and in
compliance with the requirements of all applicable laws, including, without
limitation, ERISA.

     SECTION 2.13. Title to Properties; Licenses; Insurance.  (a) Inotek does
not own any interest in any real property;

     (b) all leasehold interests for real property and any material personal
property used by Inotek in its business are held pursuant to lease agreements
which are valid and enforceable in accordance with their terms;

by Inotek complies in all material respects with all applicable zoning
requirements and other laws and regulations relating thereto, and there are no
condemnation proceedings pending or threatened with respect to any of such
properties;

     (d) Inotek has valid title or other ownership rights under licenses to all
material intangible personal or intellectual property used by Inotek in its
business, free and clear of any material claim, defense or right of any other
person or entity, subject only to rights of the licensors pursuant to applicable
license agreements, which rights do not materially and adversely interfere with
the use of such property; and

     (e) all material insurable properties owned or held by Inotek are
adequately insured by financially sound and reputable insurers in such amounts
and against fire, earthquake and other risks insured against by extended
coverage and public liability insurance, in amounts and on terms customary with
companies of similar size.

     SECTION 2.14. Environmental Matters.  As used in this Agreement,

and the Federal Occupational Safety and Health Act.

     To the best of Inotek's knowledge, neither the conduct nor operation of
Inotek nor any condition of any property presently or previously owned, leased
or operated in any capacity by Inotek violates or violated any Environmental
Law, and no condition or event has occurred with respect to any property that,
with notice or the passage of time, or both, would constitute a violation
material to the business of Inotek of any Environmental Law or obligate (or
potentially obligate) Inotek to remedy, stabilize, neutralize or otherwise alter
the environmental condition of any property. Inotek has not received notice from
any person or entity that Inotek, or the operation or condition of any property
ever owned, leased or operated in any capacity by Inotek, are or were in
violation of any Environmental Law, or that Inotek is responsible (or
potentially responsible) for remedying, or the cleanup of, any pollutants,
contaminants, or hazardous or toxic wastes, substances or materials at, on or
beneath any such property.

     SECTION 2.15. Compliance with Laws and Regulations.  Except as disclosed in

jurisdiction in which such qualification is required and is in compliance in all
material respects with all applicable laws, ordinances and regulations.

commissions, investment banking fees, financial advisory fees, finders' fees or
similar compensation payable by Inotek in connection with the transactions
contemplated by this Agreement.

     SECTION 2.17. No Undisclosed Liabilities.  Inotek does not have any
material liability, whether known or unknown, asserted or unasserted, absolute
or contingent, accrued or unaccrued, liquidated or unliquidated, and whether due
or to become due (and there is no past or present fact, situation, circumstance,
condition or other basis for any present or future action, suit or proceeding,
hearing, charge, complaint, claim or demand against Inotek giving rise to any
such liability), except (i) liabilities reflected in the Inotek Financial
Statements,(ii) liabilities of the same type incurred in the ordinary course of
business since February 28, 2001, and (iii) liabilities described in Section

with the SEC or any regulatory authority in connection with the transactions
contemplated hereby, at the respective times such documents are filed, and, in

     given immediately following such transaction or action;

          (d) Inotek shall promptly notify Davis of the occurrence of any matter

                                        11

          (e) Inotek shall not solicit or encourage, or hold discussions or
     negotiations with or provide information to any person or entity in

          (f)(i) Inotek will maintain cash and cash equivalent balances of not
     less than $750,000.00, less the following extraordinary expenses actually
     incurred by Inotek in connection with the Merger: (A) fees and expenses
     charged by Sanders Morris Harris Inc. with respect to the fairness opinion
     referred to in Section 6.01(g), in the amounts set forth in Section 4.01(f)
     of the Disclosure Schedule; (B) reasonable nonrecurring legal and
     accounting fees, printing and filing costs and other similar expenditures
     associated with the transaction, not exceeding an aggregate cost of
     $75,000.00 or such greater amount as may be agreed to by Davis; and (C) a
     severance payment to be made by Inotek to Dennis Stone in accordance with
     the letter dated May 25, 2000 included in Section 2.09 of the Disclosure
     Schedule. In determining compliance with this provision, to the extent that
     holders of Inotek Options (other than Dennis Stone) exercise any of such
     options prior to the Closing on a "net" or "cashless" basis (i.e., upon
     exercise, the optionee delivers to Inotek in payment of the exercise price
     that number of shares of Inotek common that, when multiplied by the current
     market value of the Inotek Common, equal the aggregate exercise price),
     thereby reducing the aggregate cash payments required to be made by Davis
     in payment of the Common Share Merger Price, an amount equal to the number
     of Inotek Common shares received by Inotek upon such exercises of options
     multiplied by the Common Share Merger Price shall be added to Inotek's cash
     and cash equivalent balances; provided further, that a "net" or "cashless"

     such effect in calculating Inotek's cash and cash equivalent balances; and

          (ii) Inotek will maintain inventory with a value equal to or exceeding

its representations or agreements contained or referred to herein, give prompt
written notice thereof to Davis and use its best efforts to prevent or promptly
remedy the same.

applicable time limitations, Inotek shall (i) prepare and file with the SEC an
Information Statement (the "Information Statement") with respect to the Merger
and the other transactions contemplated by this Agreement, (ii) cause such
Information Statement to be mailed to all Inotek stockholders and (iii) perform
all other actions required by Section 14 of the Exchange Act, and the rules and
regulations thereunder. Prior to filing the Information Statement with the SEC,
Inotek shall provide a draft thereof to Davis and its counsel, allow Davis a
reasonable period of time to review and comment on the contents of such draft,
and consider in good faith any comments submitted by Davis.

     SECTION 4.04. Consummation of Agreement.  Inotek shall perform and fulfill
all conditions and obligations on its part to be performed or fulfilled pursuant

Davis and shall cooperate fully with Davis in seeking such approvals and in
consummating the transactions contemplated by this Agreement.

     SECTION 4.05. Access to Information.  Inotek shall permit Davis reasonable
access, in a manner which will avoid undue disruption or interference with its
normal operations, to Inotek's properties. Inotek shall disclose and make
available to Davis all books, documents, papers and records relating to the

litigation files, plans affecting employees, and any other business activities
or prospects in which Davis may have a reasonable and legitimate interest in
furtherance of the transactions contemplated by this Agreement. Davis will hold
any such information which is nonpublic in confidence in accordance with the
provisions of Section 8.01 hereof.

     SECTION 4.06. Consents of Third Parties.  Inotek shall use its commercially
reasonable best efforts to obtain all consents of third parties necessary or
desirable for the consummation of the transactions contemplated by this

the date hereof, Inotek shall deliver to Davis monthly unaudited balance sheets
and profit and loss statements of Inotek prepared for its internal use and all
other financial reports or statements submitted to regulatory authorities after
the date hereof (collectively, the "Subsequent Financial Statements"). The
Subsequent Financial Statements shall be prepared on a basis consistent with
past accounting practices, shall fairly present the financial condition and
results of operations for the dates and periods presented and shall not include
any material assets or omit to state any material liabilities, absolute or
contingent, or other facts, which inclusion or omission would render such
financial statements misleading in any material respect.

     SECTION 5.01. Conduct of Business.  Davis shall not, without the prior
written consent of Inotek, engage in any transaction or take any action that

warranties of Davis contained in Article III hereof, if such representations and

shall promptly notify Inotek of the occurrence of any matter or event known to
and directly involving Davis that is materially adverse to the ability of Davis

     SECTION 5.02. Breaches.  Davis shall, in the event it has knowledge of the

remedy the same.

          (f) Inotek shall have received a fairness opinion of Sanders Morris

     Inotek from a financial point of view

                                  TERMINATION

     SECTION 7.01. Mutual Agreement.  This Agreement may be terminated by the
mutual written agreement of the parties at any time prior to the Closing Date,
regardless of whether approval of this Agreement and the Merger by the
stockholders of Inotek shall have been previously obtained.

     SECTION 7.02. Breach of Agreements.  In the event that there is a material
breach of any of the representations and warranties or agreements of Davis or
Inotek, which breach is not cured within 15 days after notice to cure such
breach is given to the breaching party by the non-breaching party, then the non-
breaching party, regardless of whether approval of this Agreement and the Merger
by the stockholders of Inotek shall have been previously obtained, may terminate
and cancel this Agreement by providing written notice of such action to the
other party hereto.

     SECTION 7.03. Failure of Conditions.  In the event that any of the
conditions to the obligations of a party are not satisfied or waived on or prior
to the Closing Date, and if any applicable cure period provided in Section 7.02
hereof has lapsed, then such party may, regardless of whether approval of the
transactions contemplated by this Agreement by the stockholders of Inotek shall
have been previously obtained, terminate and cancel this Agreement by delivery
of written notice of such action to the other party.

     SECTION 7.04. Unilateral Termination.  If the Closing Date shall not have
occurred on or prior to the day which is 120 days after the date of this
Agreement, then this Agreement may be terminated by any party by giving written
notice to the other party.

     SECTION 7.05. Effect of Termination.  Each party's right of termination
under this Article VII is in addition to any other rights it may have under this
Agreement or otherwise, and the exercise of a right of termination shall not
constitute an election of remedies. If this Agreement is terminated pursuant to
Section 7.01, 7.02, 7.03 or Section 7.04, all further obligations of the parties
under this Agreement will terminate, except that (i) the obligations in Sections
8.01, 8.03 and 8.06 will survive, and (ii) if this Agreement is terminated by a
party pursuant to Section 7.02 or 7.03 because of a breach of this Agreement by
the other party or because one or more of the conditions to the terminating
party's obligations hereunder has not been satisfied as a result of the other
party's failure to comply with any of its obligations under this Agreement, any
legal remedies to which the parties are entitled will survive such termination.

                                  ARTICLE VIII

that may be provided to the others, irrespective of the form of the
communications, by such party's employees or agents. Such Information shall not
include information which is or becomes generally available to the public other
than as a result of a disclosure by a party or its representatives in violation
of this Agreement. The parties agree that the Information will be used solely
for the purposes contemplated by this Agreement and that such Information will
not be disclosed to any person other than employees and agents of a party who
are directly involved in implementing the Merger, who shall be informed of the
confidential nature of the Information and directed individually to abide by the
restrictions set forth in this Section 8.01. The Information shall not be used
in any way detrimental to a party, including use directly or indirectly in the
conduct of the other party's business or any business or enterprise in which
                                        15

responsive disclosure.

     SECTION 8.03. Return of Documents.  Upon termination of this Agreement
