                                 August 9, 1996




Dear Fellow Shareholders:

         You  are  cordially   invited  to  attend  a  Special  Meeting  of  the
Shareholders  of Optical  Corporation of America ("OCA") to vote on the proposed
acquisition of OCA by Optical  Coating  Laboratory,  Inc.  ("OCLI")  through the
merger  (the  "Merger")  of OCA with a  wholly-owned  subsidiary  of OCLI.  Upon
consummation of the Merger, you will receive,  in exchange for each share of OCA
Common Stock that you own on the effective  date of the Merger,  2.042 shares of
OCLI Common  Stock.  Based on the closing price of OCLI Common Stock as reported
by NASDAQ on August 6,  1996,  of $14.75 per share,  the Merger is  expected  to
provide  approximately $30.12 in value of OCLI Common Stock in exchange for each
share of OCA Common Stock.  However,  the closing price of the OCLI Common Stock
on the effective date of the Merger may be more or less than $14.75. Ten percent
of the  shares of OCLI  Common  Stock you would be  entitled  to  receive in the
Merger will be held in escrow to provide indemnification to OCLI against damages
incurred  as a result of any  misrepresentations,  breaches  of  warranties  and
breaches  of  covenants  in  connection  with the  Merger.  See "THE  MERGER  --
Indemnification of OCLI; Escrow."

         At the Special Meeting, Shareholders will be asked to approve and adopt
the Agreement and Plan of Merger.

         The Special Meeting will be held at OCA's corporate  offices located at
170 Locke Drive,  Marlborough,  Massachusetts  01752, on Tuesday,  September 10,
1996, beginning at 10:00 a.m.

         Management believes the Merger and the related  transactions are in the
best  interests of OCA and its  Shareholders  and  recommends  that you vote FOR
approval of these matters. For information  concerning  Management's reasons for
making this  recommendation,  please read carefully the sections in the enclosed
Proxy Statement/Prospectus entitled "THE MERGER."

         It is very  important  that your shares be  represented  at the Special
Meeting,  whether or not you plan to attend  personally.  Therefore,  you should
complete and sign the  enclosed  proxy card and return it as soon as possible in
the  enclosed  postage-paid  envelope.  This will  insure  that your  shares are
represented at the Special Meeting.

                                             Yours very truly,



                                             Donald A. Johnson, Chairman

                          TO BE HELD SEPTEMBER 10, 1996

                               -------------------

         To the Holders of Common Stock of OPTICAL CORPORATION OF AMERICA:

         NOTICE IS HEREBY GIVEN that a Special Meeting of the Shareholders  (the
"Special   Meeting")  of  Optical   Corporation  of  America,   a  Massachusetts
corporation ("OCA"), will be held at the corporate offices of OCA located at 170
Locke Drive, Marlborough, Massachusetts 01752, on Tuesday, September 10, 1996 at
10:00 a.m. for the following purposes,  all of which are more fully described in
the accompanying Proxy Statement/Prospectus:

         1. To  consider  and vote  upon a  proposal  to  approve  and adopt the
Agreement  and Plan of Merger,  dated June 28,  1996 (the  "Merger  Agreement"),
among OCA, Optical Coating Laboratory,  Inc., a Delaware  corporation  ("OCLI"),
and OCA Acquisition Corp. ("Acquisition Corp."), a Delaware corporation which is
a wholly-owned subsidiary of OCLI, providing, among other things, for the merger
of Acquisition  Corp.  with and into OCA (the  "Merger")  pursuant to which each
share of OCA's  common  stock,  $.01 par value per share ("OCA  Common  Stock"),
outstanding  at the effective time of the Merger (other than shares with respect
to which  dissenters'  rights are perfected) will be converted into 2.042 shares
of OCLI's common stock, $.01 par value per share ("OCLI Common Stock"),  and OCA
will become a wholly-owned  subsidiary of OCLI,  all as more fully  described in
the  accompanying  Proxy  Statement/Prospectus.  A copy of the Merger  Agreement
(including the principal  exhibits  thereto) is available  without charge,  upon
written or oral request,  from Optical Corporation of America,  170 Locke Drive,
Marlborough,  Massachusetts 01752, Attention:  Clerk; telephone: (508) 481-9860,
facsimile:  (508) 481-3559.  In order to ensure timely delivery of the documents
requested, any such request should be made by August 16, 1996.

         2. To  transact  such other  business as may  properly  come before the
Special Meeting or any adjournments or postponements thereof.

         The record  date for the  determination  of  Shareholders  entitled  to
notice  of  and  to  vote  at the  Special  Meeting,  and  any  adjournments  or
postponements  thereof,  is August 9, 1996 (the "Record Date").  Only holders of
record of shares of OCA Common Stock at the close of business on the Record Date
are  entitled  to notice of and to vote at the  Special  Meeting.  A list of OCA
Shareholders  entitled to vote at the Special Meeting will be available,  during
normal business hours, at OCA's corporate offices, 170 Locke Drive, Marlborough,
Massachusetts 01752, for 10 days prior to the Special Meeting for examination by
any OCA Shareholder for purposes germane to the Special Meeting.

         Holders of OCA Common  Stock have a right to dissent  from the  Merger,
and if the Merger is  consummated,  to receive  "fair value" for their shares in
cash by complying with the provisions of 

<PAGE>

Massachusetts  law,  including  Sections  85  to  98  of  Chapter  156B  of  the
Massachusetts  Business  Corporation  Law, the full text of which is attached as
APPENDIX I to the Proxy Statement/Prospectus accompanying this Notice of Special
Meeting.

         If the  Merger is  approved  by the  Shareholders  at the  Meeting  and
effected by OCA, any Shareholder (1) who files with OCA before the taking of the
vote on the approval of the Merger, written objection to the Merger stating that
such  Shareholder  intends to demand payment for such  Shareholder's  OCA Common
Stock if the Merger is  completed  and (2) whose  shares of OCA Common Stock are
not voted in favor of the  Merger has or may have the right to demand in writing
from OCA, within twenty (20) days after the date of mailing to such  Shareholder
of notice in writing  that the Merger has  become  effective,  payment  for such
Shareholder's  shares of OCA Common Stock and an appraisal of the value thereof.
OCA and any such Shareholder  shall in such cases have the rights and duties and
shall follow the procedure set forth in Sections  88-98,  inclusive,  of Chapter
156B of the General Laws of Massachusetts.

         Your vote is very important regardless of how many shares of OCA Common
Stock you own. Regardless of whether you plan to attend the Special Meeting, you
are requested to sign,  date and return the enclosed  Proxy without delay in the
enclosed postage-paid  envelope.  You may revoke your Proxy at any time prior to
its exercise.  If you are present at the Special Meeting or any  adjournments or
postponements  thereof,  you may revoke  your Proxy and vote  personally  on the
matters properly  brought before the Special  Meeting. 

                                  By Order of the Board of Directors



                                  Robert DeN. Cope, Assistant Clerk

                                     SUMMARY

         The  following  is a summary of certain  information  contained in this
Proxy Statement/Prospectus  concerning the proposed merger (the "Merger") of OCA
Acquisition  Corp.,  a Delaware  corporation  ("Acquisition  Corp.")  which is a
wholly-owned  subsidiary  of  Optical  Coating  Laboratory,   Inc.,  a  Delaware
corporation   ("OCLI"),   with  and  into  Optical  Corporation  of  America,  a
Massachusetts   corporation   ("OCA").   Acquisition   Corp.   has  been  formed
specifically for the purpose of carrying out the Merger.  It is anticipated that
the Merger will be  consummated on or about  September 10, 1996 (the  "Effective
Date"). This summary should be read in conjunction with, and is qualified in its
entirety  by  reference  to, the full text of this  Proxy  Statement/Prospectus,
including the exhibits hereto. Each Shareholder is, therefore, urged to read the
entire Proxy Statement/Prospectus with care.

The Special Meeting

         The Special  Meeting.  A Special Meeting of Shareholders of OCA will be
held on September 10, 1996,  at 10:00 a.m. at the  corporate  offices of Optical
Corporation of America, 170 Locke Drive,  Marlborough,  Massachusetts 01752 (the
"Special Meeting"). Shareholders of record at the close of business on August 9,
1996  (the  "Record  Date")  will be  entitled  to  notice of and to vote at the
Special Meeting. The date of the mailing of this Proxy  Statement/Prospectus  to
Shareholders of OCA will be on or about August 9, 1996. At the close of business
on the Record Date,  there were  outstanding and entitled to vote 794,577 shares
of common stock,  $.01 par value, of OCA (the "OCA Common Stock"),  all of which
are expected to be  outstanding  and entitled to vote on the date of the Special
Meeting.  See "NOTICE OF SPECIAL  MEETING --  Ownership of OCLI Common Stock and
OCA Common Stock."

         The  purpose  of the  Special  Meeting  is to vote upon a  proposal  to
approve  an  Agreement  and Plan of Merger  dated  June 28,  1996  (the  "Merger
Agreement"), entered into by and among OCLI, Acquisition Corp. and OCA, pursuant
to which  Acquisition  Corp.  will merge with and into OCA, and OCLI will become
the owner of all the issued and outstanding shares of OCA Common Stock (see "THE
MERGER").  The Merger Agreement  (including the principal  exhibits thereto) are
available without charge, upon written or oral request, from Optical Corporation
of America, 170 Locke Drive, Marlborough, Massachusetts 01752, Attention: Clerk;
telephone: (508) 481-9860,  facsimile: (508) 481-3559. In order to ensure timely
delivery of the documents  requested,  any such request should be made by August
16, 1996.

                                       4
<PAGE>

         Required  Vote.   Approval  of  the  Merger   Agreement   requires  the
affirmative  vote of the holders of two-thirds of the outstanding  shares of OCA
Common Stock.

The Merger

         Effective Date. The Merger shall become effective upon the later of the
date of filing of a  Certificate  of Merger with the  Secretary  of State of the
State of Delaware  pursuant to Section 252 of the Delaware  General  Corporation
Law and the date of filing of Articles of Merger with the  Secretary of State of
the  Commonwealth of Massachusetts  pursuant to Section 79 of the  Massachusetts
Business  Corporation Law (the  "Effective  Date").  It is anticipated  that the
Effective Date will be on or about September 10, 1996.

         Exchange of Shares; Fractional Shares. Upon consummation of the Merger,
each  outstanding  share of OCA Common  Stock  (other  than shares held in OCA's
treasury  and shares  with  respect to which  statutory  dissenters'  rights are
perfected)  will be  converted  into the right to receive  2.042  shares of OCLI
Common Stock, $.01 par value (the "OCLI Common Stock"), and OCLI will become the
owner of all of the  issued  and  outstanding  shares of OCA  Common  Stock.  No
fractional  shares of OCLI Common  Stock will be issued in  connection  with the
Merger.  Any OCA Shareholder  otherwise  entitled to a fractional  share of OCLI
Common  Stock as a result of the  Merger  shall  receive  cash in lieu  thereof,
without interest,  in an amount determined by multiplying such OCA Shareholder's
fractional interest by the closing price of OCLI Common Stock as reported on the
Nasdaq  National  Market  System  on the  Effective  Date.  See "THE  MERGER  --
Procedure For Exchange of Shares; Fractional Shares."

         Based on the number of outstanding shares of OCA Common Stock as of the
Record  Date,  and on the  assumption  that  (i)  no OCA  Shareholders  exercise
appraisal rights,  (ii) no OCA Options are exercised prior to the Effective Date
(iii) OCA  purchases,  prior to the  Effective  Date,  the 46,875  shares of OCA
Common  Stock  held  by  The  Perkin-Elmer   Corporation   ("Perkin-Elmer")   in
satisfaction of an obligation to Perkin-Elmer  which has been outstanding  since
August 31, 1995,  and (iv) OCA Warrants to purchase  86,000 shares of OCA Common
Stock are exercised  prior to the Effective Date as  contemplated  by the Merger
Agreement  approximately 1,702,419 shares of OCLI Common Stock will be issued to
former OCA  Shareholders  upon the  consummation of the Merger and an additional
132,731  shares of OCLI Common  Stock will be  reserved  for  issuance  upon the
exercise of the options and warrants to purchase OCA Common Stock outstanding as
of the  Effective  Date (the "OCA  Options" and the "OCA  Warrants")  assumed by
OCLI.  As a  result,  11,430,548  shares  of  OCLI  

                                       5
<PAGE>

Common Stock will then be outstanding,  of which approximately 1,702,419 shares,
representing approximately 14.9% of the total, will be held by former holders of
OCA Common Stock.

         Assumption of OCA Stock  Options and OCA  Warrants.  At or prior to the
Effective  Date,  OCLI and OCA  shall  take all  action  necessary  to cause the
assumption by OCLI as of the Effective Date of the then  outstanding OCA Options
and OCA  Warrants.  Each of the OCA  Options  and  the  OCA  Warrants  shall  be
converted without any action on the part of the holder thereof into an option to
purchase  shares of OCLI Common Stock as of the Effective Date. As of the Record
Date,  41,000 shares of OCA Common Stock were subject to outstanding OCA Options
and 110,000 shares of OCA Common Stock were subject to outstanding OCA Warrants,
which would be equivalent  to a total of  approximately  308,742  shares of OCLI
Common  Stock  after  conversion.  See "THE  MERGER --  Assumption  of OCA Stock
Options and OCA Warrants."

         Indemnification  of OCLI;  Escrow.  Ten  percent  of the shares of OCLI
Common  Stock  issued in the  Merger  will be placed  in escrow  (the  "Escrowed
Shares") and held  pursuant to the  Indemnification  and Stock Escrow  Agreement
attached as Exhibit A to the Merger  Agreement  (the  "Escrow  Agreement").  The
Escrowed  Shares  will be reserved to provide  indemnification  to OCLI  against
damages incurred as a result of  misrepresentations,  breaches of warranties and
breaches of covenants  contained in the Merger  Agreement,  the Escrow Agreement
and the other agreements executed in connection therewith, and to satisfy claims
of OCLI arising as a result of the Merger  Agreement,  the Escrow  Agreement and
such other  agreements.  See Article 3 of the Merger  Agreement and Section 4 of
the Escrow  Agreement for a description of the  representations,  warranties and
covenants  that are  covered by the Escrow  Agreement.  In the event OCLI has an
appropriate  claim for  indemnification,  shares of OCLI  Common  Stock  will be
returned to OCLI in satisfaction of the claim. However, OCLI will be entitled to
indemnification only if and when the total of all Indemnifiable  Amounts exceeds
$250,000,  at which  point  OCLI will be  entitled  to  indemnification  for all
Indemnifiable  Amounts,  and not just  those in excess of  $250,000.  The Escrow
Agreement  requires the Escrow Agent to deliver to the Shareholders the Escrowed
Shares  remaining in escrow after the date of the  completion of the first audit
of OCA covering a period ending after the Effective  Date,  except that if there
is a claim  by OCLI at or prior to such  date,  the  Escrow  Agent  will  retain
Escrowed  Shares in an amount  sufficient  to cover such  claims  until they are
resolved. See "THE MERGER -- Indemnification of OCLI; Escrow."

                                       6
<PAGE>

         Conditions to the Merger. The consummation of the Merger is conditioned
upon,  among other  things,  (i)  approval of the Merger and the adoption of the
Merger Agreement by OCA  Shareholders,  (ii) the holders of not more than 10% of
the shares of OCA Common  Stock having  demanded  their right to an appraisal of
their OCA Common Stock,  and (iii) the  representations  and  warranties of each
party to the Merger  Agreement  being true and correct as of the Effective  Date
and the  satisfaction of certain other  conditions.  The Merger Agreement may be
terminated by the mutual  consent of the Boards of Directors of OCLI and OCA. If
the Merger is not consummated,  OCA intends to operate in substantially the same
manner as it has in the past.  Any of the conditions to the Merger may be waived
at any time prior to the Merger by the party or parties to the Merger  Agreement
benefiting from such conditions.  However, no assurance can be given that any of
such parties will determine to waive any unfulfilled conditions. See "THE MERGER
- -- Conditions to Consummation of the Merger."

         Certain  Effects  of the  Merger.  If the  Merger is  consummated,  the
holders of OCA Common  Stock (other than holders of shares with respect to which
dissenters'  rights are perfected)  will exchange their shares of stock for OCLI
Common Stock. The rights of OCA  Shareholders,  which are presently  governed by
Massachusetts  law and by the Articles of  Organization  and the By-Laws of OCA,
each as amended,  will be governed by Delaware  law and the Amended and Restated
Certificate of  Incorporation  and By-Laws of OCLI.  Certain  differences in the
rights of OCA  Shareholders  will arise as a result of this change in  governing
law as well as from  distinctions  between  the  Articles  of  Organization  and
By-Laws  of OCA,  as  amended,  and the  Amended  and  Restated  Certificate  of
Incorporation  and By-Laws of OCLI.  See "THE  MERGER -- Certain  Effects Of The
Merger" and "Comparison of Rights of Holders of OCLI Common Stock and OCA Common
Stock."

         Interests of Certain  Persons in the Merger.  Upon  consummation of the
Merger, all members of OCA's Board of Directors will resign, and OCLI intends to
name  Herbert M.  Dwight,  Jr.,  Donald A.  Johnson  and Joseph C. Zils to OCA's
Board. OCLI expects Mr. Dwight,  who is Chairman and President of OCLI, to serve
as Chairman of OCA's Board.  OCLI currently intends that certain of the existing
officers of OCA will retain their  offices  after the  Effective  Date,  but may
appoint  additional  officers of OCA.  See "THE MERGER --  Interests  of Certain
Persons in the Merger," and "OCLI AND OCA MANAGEMENTS -- Executive  Officers and
Directors of OCA."

                    NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

Rights of Dissenting Shareholders

         Under Massachusetts law, Shareholders who have not voted for the Merger
Agreement  (collectively,   "Dissenting   Shareholders"),   may,  under  varying
circumstances,  receive  cash  in  the  amount  of the  fair  market  value  (as
determined by agreement with OCA or by a court decision) of their shares in lieu
of the shares of OCLI Common Stock they would  otherwise  receive in the Merger.
Such  Dissenting  Shareholders  must (i) deliver to OCA,  before the vote on the
Merger  Agreement  is taken  at the  Special  Meeting,  written  notice  of such
Dissenting Shareholders' intent to demand payment for their shares of OCA Common
Stock and (ii) not vote such  shares of OCA Common  Stock in favor of the Merger
Agreement.  Dissenting Shareholders must also comply with the other requirements

         The OCA Common Stock is not currently,  and has never  previously been,
traded on any established  public market.  Price quotations for OCA Common Stock
are, therefore, not available.

         As of the Record Date,  there were 1,029 record  holders of OCLI Common
Stock and 49 record holders of OCA Common Stock.

Ownership of Securities

         At the Record Date,  there were a total of 794,577 shares of OCA Common
Stock  outstanding  all of which are expected to be outstanding  and entitled to
vote  on the  date of the  Special  Meeting.  Accordingly,  the  Merger  will be
approved if 529,718 shares of OCA Common Stock are voted in favor of the Merger.
As of the Record Date, OCA's directors,  officers,  their respective  affiliates
and family  members held,  directly or  indirectly,  529,793 shares of 

                                       9
<PAGE>

OCA Common  Stock,  or  approximately  66.7% of the  shares of OCA Common  Stock
outstanding as of such date. See "THE MERGER -- Interests of Certain  Persons in
the Merger" and "OWNERSHIP OF OCA COMMON STOCK AND OCLI COMMON STOCK."

         At the date hereof,  approximately  2.08% of the shares of  outstanding
OCLI Common Stock entitled to vote are held by directors and executive  officers
of OCLI and their  affiliates.  The vote of stockholders of OCLI is not required
to approve  the Merger  Agreement  or to  consummate  the Merger.  See  "SPECIAL
MEETING -- Voting and Revocation of Proxies."

Resale of OCLI Common Stock Received in the Merger; Affiliates

         Certain  officers,  directors  and principal  Shareholders  of OCA have
agreed that, until such time as financial  results covering at least thirty days
of combined  operations of OCA and OCLI have been  published by OCLI,  they will
not sell,  transfer or otherwise dispose of, or offer or agree to sell, transfer
or  otherwise  dispose  of any  shares of OCLI  Common  Stock  received  by them
pursuant  to the Merger or any  securities  which may be paid as a  dividend  or
otherwise  distributed thereon or with respect thereto or issued or delivered in
exchange  or  substitution  therefor.  See "THE  MERGER -- Resale Of OCLI Common
Stock Received In The Merger; Affiliates."

         The Registration Statement and this Proxy  Statement/Prospectus  do not
relate to or cover the resale after the Effective  Date of shares of OCLI Common
Stock issued to certain  Shareholders  of OCA in the Merger who may be deemed to
be  "affiliates" of OCA and thus  "underwriters"  within the meaning of Rule 145
under the  Securities  Act of 1933, as amended (the  "Securities  Act"),  and no
person  is  authorized  to make any use of this  Proxy  Statement/Prospectus  in
connection with any such resale.  Such securities may not be publicly  reoffered
or resold by such persons except pursuant to an effective registration statement
under the Securities Act or pursuant to another applicable  exemption therefrom.
For this  purpose,  the term  "affiliate"  means any person  who,  directly,  or
indirectly through one or more intermediaries,  possesses the power to direct or
cause the direction of the management and policies of OCA,  whether  through the
ownership of OCA Common Stock, by contract, or otherwise.

Accounting Treatment; Regulatory Approvals

         The   Merger  is   expected   to  meet  all  of  the   conditions   for
pooling-of-interests  accounting. It is a condition to the obligation of OCLI to
consummate  the Merger that OCLI shall have  received an opinion from Deloitte &
Touche LLP, OCA's independent accountants,  to the effect that Deloitte & Touche
LLP, based on certain material  representations  provided by OCLI and OCA is not
aware of any fact  concerning OCA that would  preclude OCLI from  accounting for
the Merger as a pooling-of-interests.

         The  Merger is  subject to the  requirements  of the  Hart-Scott-Rodino
Antitrust   Improvements  Act  of  1976  and  the  regulations  thereunder  (the
"Antitrust   Improvements   Act"),   which  provide  that  certain   acquisition
transactions  (including  the  Merger)  may  not be  consummated  until  certain
information  has been  furnished to the Antitrust  Division of the Department of
Justice (the "Antitrust Division") and the Federal Trade Commission (the "FTC"),
and certain waiting period  requirements have been satisfied.  OCLI and OCA have
filed the required  information and material with the Antitrust Division and the
FTC,  but,  as of the date of this Proxy  Statement/Prospectus,  the  applicable
waiting  period has not yet expired.  There can be no assurance that the waiting
period will expire without a challenge to the Merger from the Antitrust Division
or the FTC.  Termination  of the waiting  period does not preclude the Antitrust
Division,  the FTC or any other  party from  challenging  or seeking to delay or
enjoin the Merger on antitrust or other grounds.  There can be no assurance that
any such challenge, if made, would not be successful;  however, neither OCLI nor
OCA believes  that the Merger will violate the antitrust  laws.  Any such action
taken or threatened  prior to the  consummation of the Merger could relieve OCLI
or OCA of their respective obligations to consummate the Merger. See "THE MERGER
- --Regulatory Approvals."

         Except for the Antitrust Improvements Act filings, and filings with the
Secretary of State of the State of Delaware and  Commonwealth of  Massachusetts,
no federal or state regulatory approvals are required in order to consummate the
Merger.

Certain Federal Income Tax Consequences

         The Merger is  intended to qualify as a tax-free  reorganization  under
Section  368(a) of the Internal  Revenue Code of 1986,  as amended (the "Code").
Neither  OCA nor OCLI  intends to  request a ruling  from the  Internal  Revenue
Service  with  respect  to the  Merger.  Assuming  that the Merger is a tax-free
reorganization,  (i) no gain or loss will be  recognized by OCLI or OCA and (ii)
no  gain  or  loss  will  be  recognized  by  Shareholders  of  OCA  other  than
Shareholders  perfecting statutory  dissenters' rights or in connection with the
cash  settlement  of  fractional  shares.  If the  Merger  fails to qualify as 

                                       11
<PAGE>

a  reorganization  under Section  368(a) of the Code, on the Effective Date each
shareholder of OCA will recognize gain or loss on the exchange of his OCA Common
Stock for OCLI Common  Stock.  Holders of OCA Common  Stock are urged to consult
with their tax advisers to determine  the  particular  tax  consequences  of the
Merger to them.

Unaudited Pro Forma Combined Selected Financial Data

         The following tables present selected historical consolidated financial
data and pro forma combined financial  information for OCLI and OCA and selected
per share data for OCLI  Common  Stock on a  historical  and pro forma  combined
basis giving  effect to the  acquisition  of 100% of the OCA shares by OCLI on a
pooling-of-interests  accounting  basis.  The  information  is derived  from the
consolidated  historical  financial  statements  of OCLI and OCA,  including the
related notes thereto,  appearing elsewhere or incorporated by reference herein.
The pro forma  statement  of income  data for each  period  gives  effect to the
Merger as if it had occurred at the beginning of such period,  and the pro forma
balance  sheet data  gives  effect to the  Merger as if it had  occurred  on the
balance sheet date. The pro forma combined  information has been prepared on the
assumption  that the  Merger  will be  accounted  for on a  pooling-of-interests
basis.  Due to  differences  in reporting  periods,  OCA's results for the three
months  ended  September  30, 1994 were not  included in the pro forma  combined
statements of operations.  For that three month period,  OCA reported  unaudited
revenue of $7,171,000 and unaudited net income of $91,000.

         Redeemable   common  stock   represents   amounts  payable  by  OCA  to
Perkin-Elmer  upon surrender of 46,875 shares of OCA common stock. The pro forma
data does not reflect payment for the shares.

         Historical  book  value  per  share for OCLI is  computed  by  dividing
stockholders'  equity by the number of shares of common stock outstanding at the
end of the  period.  Historical  book  value per share  for OCA is  computed  by
dividing  stockholders' equity by the number of shares outstanding of OCA at the
end of the period  multiplied by 2.042.  Pro forma combined book value per share
is computed  by dividing  pro forma  combined  number of shares of common  stock
outstanding  at the end of the period after giving  effect to the common  shares
added pursuant to the merger.

         These data are not necessarily  indicative of the results of the future
operations of the combined entity or the actual results that would have occurred
had the Merger been consummated prior to the periods indicated.

                                 SPECIAL MEETING

General

         This Proxy  Statement/Prospectus  is being  furnished to holders of OCA
Common  Stock in  connection  with the  solicitation  of proxies by the Board of
Directors of OCA for use at the OCA Special Meeting, which will be held at OCA's
corporate offices located at 170 Locke Drive, Marlborough,  Massachusetts 01752,
on  September  10,  1996  beginning  at 10:00 a.m.  and at any  adjournments  or
postponements thereof. This Proxy  Statement/Prospectus is accompanied by a form
of proxy for use at the Special Meeting.

         This Proxy Statement/Prospectus also constitutes the Prospectus of OCLI
with  respect to the shares of OCLI  Common  Stock to be issued  pursuant to the
Merger,  which Prospectus is part of a Registration  Statement on Form S-4 filed
by OCLI with the  Commission  under the  Securities Act of 1933, as amended (the
"Securities Act").

         No vote by the  stockholders  of OCLI is  required  to  consummate  the
Merger.

Purposes; Recommendation of the OCA Board of Directors and Management

         The purposes of the Special Meeting are (i) to consider and vote upon a
proposal  to  adopt  and  approve  the  Merger  Agreement  and the  transactions
contemplated  thereby and (ii) to transact  such other  business as may properly
come before the Special Meeting and any adjournments or  postponements  thereof.
The Board of Directors of OCA is not presently aware of any such other business.

         The  management  of OCA and OCA's Board of Directors  have approved the
Merger  Agreement  and the  transactions  contemplated  thereby  and believe the
Merger and the other transactions  contemplated by the Merger Agreement are fair
to and in the best interests of OCA and its Shareholders.

         THE MANAGEMENT AND BOARD OF DIRECTORS OF OCA RECOMMEND THAT OCA
         SHAREHOLDERS VOTE IN FAVOR OF THE ADOPTION AND APPROVAL OF THE
                               MERGER AGREEMENT.

Record Date

         Only  holders of record of OCA Common Stock as of the close of business
on August 9, 1996 are  entitled to receive  notice of and to vote at the Special
Meeting  and any  adjournments  or  postponements  thereof.  As of the  close of
business on August 9, 1996, 794,577 shares of OCA Common Stock were outstanding,
all of which are expected to be outstanding  and entitled to vote as of the date
of the Special  Meeting.  Each share of OCA Common Stock is entitled to one vote
upon each 



                                       28
<PAGE>


matter properly  submitted at the Special Meeting.  See "THE MERGER -- Interests
of Certain  Persons in the Merger" and  "OWNERSHIP  OF OCA COMMON STOCK AND OCLI
COMMON STOCK."

Votes Required

         Under  Massachusetts law and pursuant to OCA's Articles of Organization
and the OCA By-Laws,  each as amended,  the  affirmative  vote of the holders of
two-thirds  of the  outstanding  shares of OCA Common Stock is required to adopt
and approve the Merger Agreement and the transactions contemplated thereby.

         The  presence,  in person or by proxy,  at the  Special  Meeting of the
holders of at least a majority  of the votes  entitled to be cast at the Special
Meeting is necessary to  constitute  a quorum for the  transaction  of business.
Abstentions will be counted as present for the purposes of determining whether a
quorum is  present  but will not be counted as votes cast in favor of the Merger
Agreement.  Because the vote on the Merger  Agreement  requires  the approval of
two-thirds  of the votes  entitled to be cast by the holders of the  outstanding
shares of OCA Common Stock,  abstentions will have the same effect as a negative
vote on these proposals.

         As of the Record Date, the directors and officers of OCA, together with
their respective affiliates and family members,  owned directly or indirectly an
aggregate  of 529,793  shares of OCA Common  Stock,  constituting  approximately
66.7% of the then outstanding shares of OCA Common Stock expected to be entitled
to vote at the Special  Meeting.  Each of the  directors and officers of OCA has
agreed  with  OCLI to vote  his  shares  of OCA  Common  Stock  in  favor of the
proposals to adopt and approve the Merger  Agreement.  The  affirmative  vote of
these individuals, together with the affirmative vote of their respective family
members,  virtually ensures the adoption and approval of the Merger Agreement by
the OCA Shareholders  without regard to the votes of any other OCA Shareholders.
In  addition,  employees  own  another  54,500  of  the  shares  expected  to be
outstanding and entitled to vote at the Special Meeting.



                                       29

Voting and Revocation of Proxies

         Shares  of  OCA  Common  Stock  that  are  entitled  to  vote  and  are
represented by a proxy  properly  signed and received at or prior to the Special
Meeting,  unless subsequently properly revoked, will be voted in accordance with
the instructions  indicated  thereon.  If a proxy is signed and returned without
indicating any voting  instructions,  shares of OCA Common Stock  represented by
such  proxy  will be voted FOR the  proposal  to adopt and  approve  the  Merger
Agreement.  The Board of Directors of OCA is not currently aware of any business
to be acted upon at the Special  Meeting  other than as  described  herein.  If,
however,  other matters are properly  brought before the Special  Meeting or any
adjournments or  postponements  thereof,  the persons  appointed as proxies will
have the  discretion  to vote or act  thereon  in  accordance  with  their  best
judgment.

         Any proxy  given  pursuant to this  solicitation  may be revoked by the
person  giving it at any time  before the shares  represented  by such proxy are
voted at the  Special  Meeting  by (i)  filing  with the  Clerk of OCA a written
notice of revocation  bearing a later date than the proxy, (ii) duly executing a
proxy  relating to the same shares bearing a later date and delivering it to the
Clerk of OCA or (iii) voting in person at the Special Meeting. Attendance at the
Special  Meeting will not in and of itself  constitute a revocation  of a proxy.
All written  notices of  revocation  and other  communications  with  respect to
revocation of proxies  should be addressed as follows:  Optical  Corporation  of
America, 170 Locke Drive,  Marlborough,  Massachusetts 01752, attention:  Clerk,
and must be received before the taking of the vote at the Special Meeting.

Solicitation of Proxies

         Each of OCLI  and OCA  will  bear  its  respective  costs  incurred  in
preparing  this  Proxy   Statement/Prospectus   (and  the  related  Registration
Statement) and the form of proxy, except that OCA will bear the costs of mailing
proxy materials to OCA Shareholders in connection with the Special  Meeting.  In
addition to solicitation by mail, directors,  officers and employees of OCA, who
will not be specifically compensated for such services, may solicit proxies from
OCA Shareholders personally or by telephone,  telecopy,  telegram or other means
of communication.

Dissenters' Rights

         Shareholders  of OCA  who do not  vote in  favor  of the  adoption  and
approval  of the Merger  Agreement  and the  transactions  contemplated  thereby
(collectively,  "Dissenting Shareholders") have certain rights to demand payment
for the "fair value" of 



                                       30
<PAGE>

their  shares of OCA Common  Stock if they  timely  provide a written  notice of
dissent  prior to the  Special  Meeting  and  strictly  comply  with  all  other
applicable  requirements  under  Massachusetts  law.  Failure to take any of the
steps required on a timely basis will result in the loss of dissenters'  rights.
Merely  voting  against or failing  to vote for the  Merger  Agreement  will not
perfect a Dissenting  Shareholder's  dissenter's  rights.  The amount obtainable
upon  the  valid  exercise  of  dissenters'  rights  cannot  be  predicted.  The
procedures to be followed by Dissenting  Shareholders  are summarized in "RIGHTS
OF  DISSENTING  SHAREHOLDERS,"  and a copy of the  applicable  provisions of the
Massachusetts  Business  Corporation Law is attached as APPENDIX I to this Proxy
Statement/Prospectus and incorporated herein by this reference.

             OCA SHAREHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES
                             WITH THEIR PROXY CARDS.

                                   THE MERGER

Background of the Merger and Related Matters


         OCLI and OCA have worked together on several projects over the past six
years. Beginning in 1990, OCLI subcontracted with OCA for the coating of missile
domes for the U.S Department of Defense. Under this arrangement,  OCA fabricated
the missile domes in its facilities in Garden Grove, California and sent them to
OCLI to be coated at its facilities in Santa Rosa. Since the initial order, OCLI
has received  several  follow-on  orders from OCA for the coating of the missile
domes, in addition to several other smaller coating subcontracts, for which OCLI
has  received  orders  worth  approximately   $657,000  since  1992,   including
approximately $40,000 of sales after the second quarter of 1996.

         Beginning  in 1995,  OCA  subcontracted  with  OCLI for the  supply  of
optical subassemblies and optical fabrication. In fiscal 1995 OCLI placed orders
with OCA worth approximately  $75,000 and orders year-to-date in fiscal 1996 are
worth $407,000,  including  approximately  $200,000 of open orders at the end of
the second quarter of 1996.

         In addition to being both  suppliers  and  customers to each other over
the last  several  years,  OCA and OCLI have both  competed  for optical  filter
business  in  the  defense,   aerospace,   medical  instrumentation  and  office
automation market segments along with other companies including, but not limited
to, Barr Associates,  Optical Filter Corporation, Varo, and Deposition Sciences,
Inc.



                                       31
<PAGE>

         In July of 1993,  Frank Bufano,  OCLI's Vice  President and Director of
Operations,  visited  OCA's  facilities  in  Massachusetts  and  met  with  John
Viggiano, OCA's Vice President and General Manager of East Coast operations,  to
review OCA's  capabilities and to discuss a possible  strategic alliance between
the  companies.  Following Mr.  Bufano's  visit,  Donald A. Johnson,  CEO of OCA
summarized  those  discussions  in a letter to Herbert M.  Dwight,  Jr.,  OCLI's
President and CEO, and suggested that Mr. Dwight and Mr. Johnson meet to discuss
a possible strategic alliance.

         On October 28, 1993, as suggested by Mr.  Johnson,  Mr. Dwight  visited
OCA's  facilities  in Garden  Grove,  California  to  review  OCA's  West  Coast
operations and to discuss a possible strategic alliance between OCA and OCLI. In
subsequent discussions between OCLI's senior managers and Board of Directors, it
was determined that further discussions with OCA at that time were not in OCLI's
best  interest in light of the other major  projects and  acquisitions  OCLI had
already  undertaken.  In November of 1993,  Mr. Dwight  informed Mr.  Johnson of
OCLI's decision not to pursue the discussions any further at that time. However,
it was agreed that the companies  should  revisit the  possibilities  in 6 to 12
months.

         On July 15,  1994,  in  response  to an  invitation  from OCA,  Dr. Jim
Seeser, OCLI's Chief Technical Officer, Glenn Yamamoto, the Product Line Manager
for OCLI's instrumentation  business, Lenn Mott, OCLI's Director of Engineering,
and  Dr.  James  Rancourt,  one  of  OCLI's  Senior  Scientists,  visited  OCA's
facilities in Garden Grove, California, to conduct a preliminary review of OCA's
business to  determine  whether  OCLI had any  interests in pursuing a strategic
business relationship. Based upon the findings of Dr. Seeser's team it was again
decided that there were current  opportunities around which the companies should
seek to form a strategic relationship.

         In April of 1995,  in a series of telephone  conversations  between Mr.
Johnson,  Mr.  Viggiano  and Mr.  Yamamoto,  OCLI learned of several new product
development efforts at OCA. During these  conversations,  OCLI was informed that
OCA's  Shareholders  were  interested  in  developing  some  liquidity for their
investments,  and it was suggested  that  representatives  of the companies meet
again to discuss a possible strategic alliance. Over the next few months various
representatives from OCLI engaged in the review of OCA's new product development
efforts and independent studies of the respective market opportunities for these
new products.

         On December 21, 1995, OCA and OCLI executed a Confidentiality Agreement
in order to allow for the exchange and discussion of OCA proprietary information
in contemplation of a possible acquisition of OCA by OCLI.




                                       32
<PAGE>

         On February  26,  1996,  OCA's Board of  Directors  met with members of
OCLI's senior management group,  including Herbert Dwight, John Markovich,  John
McCullough,  Jim Seeser,  Rick Strandlund,  Glenn Yamamoto,  and Joseph Zils, to
discuss the  proposed  acquisition  and agree in  principle  on the terms of the
transaction.

         On March 1,  1996,  OCA and OCLI  executed  a Letter of Intent  setting
forth the  general  terms of the  agreement  and  providing  a schedule  for the
execution  of  definitive  agreements.   Numerous  telephone  conversations  and
meetings  among  counsel for OCA and OCLI and among  representatives  of OCA and
OCLI subsequently ensued. During the months of March 1996 through June 20, 1996,
OCA and OCLI  negotiated  the terms of the  Agreement  and Plan of  Merger  (the
"Agreement") and related agreements.

         On June 20, 1996,  at a regularly  scheduled  meeting,  OCLI's Board of
Directors   considered   management's   recommendations  on  the  Agreement  and
unanimously  voted to adopt a resolution  authorizing  management to execute the
Agreement on behalf of OCLI.

         On  June  20,  1996,  the  Board  of  Directors  of OCA,  in a  special
telephonic  meeting,   unanimously  voted  to  adopt  a  resolution  authorizing
management  to execute the  Agreement  and to  recommend  its  adoption to OCA's
Shareholders.

         On June 28, 1996,  the companies  executed the Agreement  setting forth
the terms and  conditions  under which OCLI would  acquire  all the  outstanding
shares of OCA's stock.

OCLI's Reasons for the Merger

         OCLI's  purpose for engaging in the  transactions  contemplated  by the
Agreement is to acquire OCA.  OCLI  believes  that the  acquisition  of OCA will
provide  OCLI  with  an   established,   well-recognized   provider  of  optical
subassemblies,  optical design, and fiber optic  communication  component design
and manufacturing to both government and industry.  At the same time, OCLI hopes
both  to  identify   opportunities  to  further   commercialize  OCA's  existing
technologies  and to combine its research and development  activities with those
of OCA's with a goal of creating new  technologies.  It is anticipated  that the
Merger  will  also  allow the  companies  to  realize  additional  economies  in
manufacturing,  support service and corporate  administration.  The structure of
the Merger was established to achieve the business  objectives of OCLI, in light
of relevant financial, 



                                       33
<PAGE>

legal, tax and other considerations.

OCA's Reasons for the Merger

         OCA  believes  that a number of  significant  strategic  benefits  will
accrue from the Merger.  In addition to its established  product lines,  OCA has
recently developed an important  position in the embryonic,  but rapidly growing
market for fiber optics  products  used in  telecommunications.  These  products
incorporate narrow bandpass filters produced by using OCA's MicroPlasma(TM) thin
film coating process. OCA believes that OCLI's manufacturing capacity, access to
capital,  distribution network and international business presence as one of the
world's largest thin-film coating  manufacturers will significantly  benefit the
development, marketing, sales and distribution of OCA's product lines as well as
enable OCA to capitalize on domestic and international  business  opportunities.
There can be no assurances,  however, that the OCA Shareholders will realize all
of the benefits expected from the Merger.

         In evaluating the Merger,  the Board of Directors and management of OCA
considered,  among other  things,  (i) the OCLI Common Stock  offered by OCLI as
consideration  for the outstanding  shares and options to purchase shares of OCA
Common Stock; (ii) information concerning the management, results of operations,
performance, financial condition and prospects of OCLI; (iii) the technology and
customer base of OCLI's  businesses;  (iv) the  prospects for further  growth in
value of  OCLI's  Common  Stock;  (v)  current  economic,  industry  and  market
conditions  affecting both OCA and OCLI; (vi) the terms of the Merger Agreement;
(vii) the tax-free nature of the Merger;  and (viii) the potential impact of the
Merger  on  OCA's  employees,  suppliers  and  customers.  Based on all of these
matters,  and such other matters as OCA deemed relevant,  the Board of Directors
and  management of OCA  unanimously  support the Merger  Agreement and recommend
that the holders of the OCA Common Stock vote for its approval and adoption.

         Working  Relationships.  OCA has become well  acquainted with OCLI, its
subsidiaries,  its  management,  its products,  and its business  strategy.  See
"BACKGROUND OF THE MERGER AND RELATED MATTERS."

         Compatibility. In the opinion of OCA's management, the Merger with OCLI
will provide OCA Shareholders  with a fair value for their OCA Common Stock, and
OCA  will  become  an  important  part  of a  growing,  well-respected  business
operation,  providing  expanded  opportunities for the growth and development of
OCA's employees.


                                       34
<PAGE>

         Stockholder Value. OCA Shareholders will receive OCLI Common Stock in a
tax free  exchange.  OCLI's  Common Stock,  which is traded on the NASDAQ,  will
provide  greater  liquidity to OCA  Shareholders  than may be possible  with OCA
Common Stock.  The OCA Common Stock is not currently,  and has never  previously
been, traded on any established public market.

         Summary.  The management and the Board of Directors of OCA believe that
the terms of the Merger are fair to,  and in the best  interest  of, OCA and its
Shareholders  and  unanimously  have  approved  the  Merger  Agreement  and  the
transactions contemplated thereby.

Structure and Terms of the Merger

         If the Merger is  consummated,  the  outstanding  shares of Acquisition
Corp.  will be converted into new shares of OCA Common Stock (which will be held
by OCLI) and all of the previously outstanding shares of OCA Common Stock (other
than any such  shares held in the  treasury  of OCA and shares  with  respect to
which  dissenters'  rights are perfected)  will be converted into shares of OCLI
Common  Stock.  As a  result  of the  Merger,  OCA will  become  a  wholly-owned
subsidiary  of OCLI,  and each person who  previously  held shares of OCA Common
Stock (other than those who perfect statutory  dissenters' rights) will receive,
upon the surrender of their stock  certificates  to a designated  agent of OCLI,
2.042  shares of OCLI Common  Stock for each share of OCA Common  Stock held.  A
copy of the Merger  Agreement  (including  the principal  exhibits  thereto) are
available without charge, upon written or oral request, from Optical Corporation
of America, 170 Locke Drive, Marlborough, Massachusetts 01752, Attention: Clerk;
telephone: (508) 481-9860,  facsimile: (508) 481-3559. In order to ensure timely
delivery of the documents  requested,  any such request should be made by August
16, 1996.

         Based on the number of outstanding shares of OCA Common Stock as of the
Record  Date,  and on the  assumption  that  (i)  no OCA  Shareholders  exercise
appraisal rights, (ii) no OCA options are exercised prior to the Effective Date,
(iii) OCA  purchases,  prior to the  Effective  Date,  the 46,875  shares of OCA
Common  Stock held on the Record  Date by  Perkin-Elmer  in  satisfaction  of an
obligation to Perkin-Elmer which has been outstanding since August 31, 1995, and
(iv) OCA Warrants to purchase  86,000  shares of OCA Common Stock are  exercised
prior  to  the  Effective  Date  as  contemplated   by  the  Merger   Agreement,
approximately 1,526,807 shares of OCLI Common Stock will be issued to former OCA
Shareholders  upon the  



                                       35
<PAGE>

consummation of the Merger and an additional 132,731 shares of OCLI Common Stock
will be  reserved  for  issuance  upon the  exercise  of the OCA Options and OCA
Warrants  assumed by OCLI. As a result,  11,430,548  shares of OCLI Common Stock
will then be outstanding,  of which approximately 1,702,419 shares, representing
approximately  14.9% of the total,  will be held by former holders of OCA Common
Stock.

Assumption of OCA Stock Options and OCA Warrants

         At or prior to the Effective  Date,  OCLI and OCA shall take all action
necessary  to  cause  the  assumption  by OCLI as of the  Effective  Date of the
options  and  warrants  to  purchase  OCA  Common  Stock  outstanding  as of the
Effective Date (the "OCA Options" and "OCA  Warrants").  Each of the OCA Options
and OCA Warrants shall be converted without any action on the part of the holder
thereof  into an option to  purchase  shares of OCLI  Common  Stock  (the  "OCLI
Options" and "OCLI  Warrants") as of the Effective Date. The number of shares of
OCLI  Common  Stock that each  record  holder of an option or warrant  agreement
which  represents  OCA  Options  or  OCA  Warrants  (the   "Optionholders"   and
"Warrantholders")  shall be entitled to receive upon the exercise of such option
or warrant  shall be a number of whole  shares  determined  by  multiplying  the
number  of  shares  of OCA  Common  Stock  subject  to such  option,  determined
immediately  before the  Effective  Date, by 2.042.  The exercise  price of each
share of OCLI Common Stock subject to an assumed OCA Option or OCA Warrant shall
be the amount  (rounded up to the nearest  whole cent)  obtained by dividing the
exercise  price per share of OCA Common Stock at which such option or warrant is
exercisable  immediately  before the Effective Date by 2.042. The assumption and
substitution of OCA Options and OCA Warrants does not give the Optionholders and
Warrantholders  additional benefits which they did not have immediately prior to
the Effective Date,  result in any  acceleration of any vesting schedule for any
OCA Option or OCA Warrant or relieve the Optionholders and Warrantholders of any
obligations  or  restrictions  applicable  to their  options or  warrants or the
shares obtainable upon exercise of the options or warrants. Only whole shares of
OCLI Common Stock shall be issued upon  exercise of any former option or warrant
for OCA Common Stock,  and the holder of such option or warrant shall receive in
cash the  fair  market  value of the  fractional  share,  net of the  applicable
exercise price of the fractional share and applicable  withholding  taxes. As of
the Record Date,  41,000 shares of OCA Common Stock were subject to  outstanding
OCA Options and 110,000  shares of OCA Common Stock were subject to  outstanding
OCA  Warrants,  which would be equivalent  to a total of  approximately  308,342
shares of OCLI Common Stock after conversion.

Indemnification of OCLI; Escrow

         Upon consummation of the Merger, 10% of the shares of OCLI Common Stock
issued in the Merger will be placed in escrow (the  "Escrowed  Shares") and held
pursuant to the Indemnification and Stock Escrow Agreement attached as Exhibit A
to the Merger  Agreement (the "Escrow  Agreement").  The Escrowed Shares will be
reserved  to provide  indemnification  to OCLI  against  costs,  liabilities  or
damages incurred,  paid by or imposed upon OCLI,  Acquisition Corp. or OCA after
the Effective Date as a result of misrepresentations, breaches of warranties and
breaches of covenants  contained in the Merger  Agreement,  the Escrow Agreement
and the other agreements executed in connection therewith.  See Article 3 of the
Merger  Agreement and Section 4 of the Escrow Agreement for a description of the
representations and warranties that are covered by the Escrow Agreement.

         In the event OCLI has an appropriate claim for indemnification,  shares
of OCLI  Common  Stock held in the escrow  account  will be  returned to OCLI in
satisfaction of the claim. The amount of  indemnification to which OCLI would be
entitled with respect to an  indemnifiable  claim (the  "Indemnifiable  Amount")
shall be  determined  and computed by reference to the actual  economic  loss to
OCLI,  Acquisition  and/or OCA (and not just by  reference  to any effect on the
value of the  shares  of OCA)  and  shall  be  deemed  to  include  all  losses,
liabilities,  expenses or costs incurred by OCLI and/or  Acquisition,  including
reasonable  attorney's fees. For purposes of determining the number of shares of
OCLI Common  Stock which would be returned to OCLI in  satisfaction  of a claim,
each  share  will be valued at the  closing  price of OCLI  Common  Stock on the
Nasdaq  National  Market System on the  Effective  Date.  Thus,  for purposes of
satisfying the indemnification  requirements of the Escrow Agreement, the former
OCA Shareholders would not have the benefit of any increase, nor the risk of any
decrease, in the market price of shares of OCLI Common Stock after the Effective
Date. OCLI will be entitled to indemnification only if and when the total of all
Indemnifiable  Amounts exceeds $250,000, at which point OCLI will be entitled to
indemnification for all Indemnifiable  Amounts,  and not just those in excess of
$250,000.

         If a claim is made,  the Escrow Agent will deliver to OCLI an amount of
shares with a total value equal to the  Indemnifiable  Amount  within 30 days of
the demand  unless  written  objection  to such demand is received by the Escrow
Agent and OCLI from the Shareholder  Representative  (as defined below).  If the
Shareholder Representative objects to OCLI's claim, the dispute may be submitted
to a court of competent jurisdiction if not previously settled.




                                       37
<PAGE>

         The Escrow  Agreement  requires  the Escrow Agent to deliver to the OCA
Shareholders  the  Escrowed  Shares  remaining  in escrow  after the date of the
completion  of the  first  audit of OCA  covering  a  period  ending  after  the
Effective  Date,  except  that if  there  is a claim by OCLI at or prior to such
date, the Escrow Agent will retain  Escrowed  Shares in an amount  sufficient to
cover such claims until they are resolved. Assuming that the Effective Date will
occur prior to October 31, 1996, which is the end of OCLI's current fiscal year,
such first audit is expected to be completed  prior to the end of January  1997.
OCA is not aware of any claims  threatened  or asserted  that it expects to give
rise to a right of  indemnification  under the  Escrow  Agreement.  It should be
understood,  however, that claims may arise in amounts which would result in all
of the  Escrowed  Shares  being  either  distributed  to  OCLI  or  sold  by the
Shareholder Representative pursuant to the Escrow Agreement, in which event none
of the Escrowed  Shares would be distributed to the  Shareholders  at the end of
the escrow period.

         Shares  held in escrow  will be  registered  in the name of the  Escrow
Agent,  and each former OCA Shareholder  will be entitled to instruct the Escrow
Agent how to vote his shares  with  respect to  matters  placed  before the OCLI
Stockholders.  Former OCA Shareholders will be entitled to directly receive cash
dividends, if any, paid or declared out of earned surplus on the Escrowed Shares
during the escrow period; however, any additional shares of OCLI Common Stock or
other property that are  distributed  with respect to the Escrowed Shares during
the escrow period will be held  pursuant to the Escrow  Agreement to satisfy any
indemnification claims.

         Kenneth D. Roberts,  72 Windsor Road,  Wellesley  Hills,  Massachusetts
02181-6134, an OCA Shareholder, has agreed to serve as representative of the OCA
Shareholders   for   purposes  of  the  Escrow   Agreement   (the   "Shareholder
Representative").  Any  action  taken  by the  Shareholder  Representative  with
respect to the settlement of a claim against the Escrowed Shares will be binding
on all OCA Shareholders.  The Shareholder  Representative will have the right to
sell shares of OCLI Common  Stock held in escrow in order to obtain funds to pay
any  expenses  incurred or  anticipated  to be incurred in  connection  with his
services.

Procedure for Exchange of Shares; Fractional Shares

         Promptly   following  the  consummation  of  the  Merger,   ChaseMellon
Shareholder  Services,  acting in the capacity of exchange  agent (the "Exchange
Agent")  will  mail  to  each  former  OCA  Shareholder  a  form  of  letter  of
transmittal,  together  with  instructions  for the  exchange  of such  holder's
certificates  representing OCA Common Stock for certificates representing shares
of OCLI  Common  Stock.  Upon  surrender  to the  Exchange  Agent of one or more
certificates for OCA Common Stock together with a



                                       38
<PAGE>

properly completed letter of transmittal, the Exchange Agent will issue and mail
to the former OCA  Shareholder a certificate  representing a number of shares of
OCLI  Common  Stock that is equal to 90% of the number of shares of OCLI  Common
Stock into which such shares of OCA Common Stock have been converted pursuant to
the Merger,  and,  where  applicable,  a check for the amount  representing  any
fractional share determined in the manner described in the following  paragraph.
Under the Merger Agreement, a certificate  representing the remaining 10% of the
shares of OCLI Common Stock into which an OCA Shareholder's shares of OCA Common
Stock have been converted  will be placed in escrow and thereafter  delivered to
the OCA  Shareholder  or  returned to OCLI in  accordance  with the terms of the
Escrow Agreement. See "THE MERGER -- Indemnification of OCLI; Escrow."

         Neither  certificates  nor scrip for  fractional  shares of OCLI Common
Stock  shall be  issued  to OCA  Shareholders  and no OCA  Shareholder  shall be
entitled  to any voting or other  rights of a holder of shares for a  fractional
share  interest.  Each OCA Shareholder who otherwise would have been entitled to
receive a fraction of a share of OCLI Common  Stock shall  receive  cash in lieu
thereof,   without  interest,  in  an  amount  determined  by  multiplying  such
Shareholder's  fractional  interest by the closing price of OCLI Common Stock as
reported on the Nasdaq National Market System on the Effective Date.

             OCA SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES
              UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND
                      INSTRUCTIONS FROM THE EXCHANGE AGENT.

Management and Operations of OCA After the Merger

         It is contemplated that after the Merger,  OCA will continue to operate
as a  separate  entity  and that OCLI does not  presently  intend to change  the
domicile, name or operations of OCA. OCLI has advised OCA, however, that Herbert
M. Dwight,  Jr., Donald A. Johnson and Joseph C. Zils will be named as directors
of OCA. OCLI currently intends that certain of the existing officers of OCA will
retain  their  offices  after the  Effective  Date,  but may appoint  additional
officers of OCA from time to time.  See "OCLI AND OCA  MANAGEMENTS  -- Executive
Officers and Directors of OCA."

Effective Date

         The Merger shall become  effective upon the later of the date of filing
of a Certificate  of Merger with the Secretary of State of the State of Delaware
pursuant to Section 252 of the Delaware General  Corporation Law and the date of
filing of Articles of 



                                       39

Merger with the Secretary of State of the Commonwealth of Massachusetts pursuant
to Section 79 of the  Massachusetts  Business  Corporation  Law (the  "Effective
Date").  It is currently  expected that the  Effective  Date will be on or about
September 10, 1996.

Conduct of OCA's Business Pending the Merger

         OCA has agreed to carry on its business  prior to the Effective Date in
substantially the same manner as prior to the date of the Merger Agreement.  OCA
has further  agreed,  prior to the  Effective  Date to (i)  maintain  all of its
properties in customary repair, order and condition, reasonable wear and use and
damage covered by insurance excepted, and take all steps reasonably necessary to
maintain its  intangibles,  (ii)  maintain  insurance  upon its  properties  and

accordance  with its current  practice,  (iii) pay its taxes as they become due,

                                       41
<PAGE>

         Subject to certain  exceptions,  OCA has also  agreed that prior to the
Effective Date, it will not engage in certain types of transactions  without the
prior written consent of OCLI, including,  among other transactions,  (i) making
any changes in its management or granting any increase in  compensation or bonus
to any  member of  management  or,  except in the  ordinary  course of  business
consistent  with past  practice,  entering  into or  altering  or  amending  any
employment or consulting  contract or similar agreement,  (ii) entering into any
transaction  or contract  with any of its  shareholders,  officers,  management,
directors  or  employees or their family  members,  (iii)  creating,  incurring,
assuming,  guaranteeing,  or  otherwise  becoming  liable  with  respect  to any

existing  OCA  Options or OCA  Warrants,  or  entering  into any  commitment  or

any shares of stock, or creating or issuing any securities  convertible into any
such  shares or  convertible  into  securities  in turn so  convertible,  (viii)
declaring  any  dividends  on or in  respect  of shares  of  capital  stock;  or

this Proxy Statement/Prospectus and related proxy materials.

Accounting Treatment

         The   Merger  is   expected   to  meet  all  of  the   conditions   for
pooling-of-interests  accounting. It is a condition to the obligation of OCLI to
consummate  the Merger that 



                                       42
<PAGE>

OCLI  shall  have  received  an  opinion  from  Deloitte  &  Touche  LLP,  OCA's
independent  accountants,  to the effect that  Deloitte & Touche  LLP,  based on
material  representations from OCLI and OCA, is not aware of any fact that would
preclude OCLI from accounting for the merger as a pooling-of-interests.

Regulatory Approvals

         The Merger is subject to the requirements of the Antitrust Improvements
Act and the  regulations  thereunder,  which  provide that  certain  acquisition
transactions  (including  the  Merger)  may  not be  consummated  until  certain
information  has been  furnished to the Antitrust  Division of the Department of
Justice (the "Antitrust Division") and the Federal Trade Commission (the "FTC"),
and certain waiting period  requirements have been satisfied.  OCLI and OCA have
filed the required  information and material with the Antitrust Division and the
FTC,  but,  as of the date of this Proxy  Statement/Prospectus,  the  applicable
waiting  period has not yet expired.  There can be no assurance that the waiting
period will expire without a challenge to the Merger from the Antitrust Division
or the FTC.  Termination  of the waiting  period does not preclude the Antitrust
Division,  the FTC or any other  party from  challenging  or seeking to delay or
enjoin the Merger on antitrust or other grounds.  There can be no assurance that
any such challenge, if made, would not be successful;  however, neither OCLI nor
OCA believes  that the Merger will violate the antitrust  laws.  Any such action
taken or threatened  prior to the  consummation of the Merger could relieve OCLI
or OCA of their respective obligations to consummate the Merger.

Resale of OCLI Common Stock Received in the Merger; Affiliates

         Certain  officers,  directors  and principal  Shareholders  of OCA have
entered  into an  agreement  with OCA and with  OCLI,  in the form  attached  as
Exhibit C to the Merger  Agreement,  pursuant  to which they have  agreed  that,
until such time as financial  results  covering at least thirty days of combined
operations  of OCA and OCLI have  been  published  by OCLI,  they will not sell,
transfer  or  otherwise  dispose  of,  or offer or  agree to sell,  transfer  or
otherwise  dispose of any shares of OCLI Common Stock  received by them pursuant
to the Merger or any  securities  which may be paid as a dividend  or  otherwise
distributed  thereon or with respect  thereto or issued or delivered in exchange
or  substitution  therefor.  Legends  restricting the transfer of such shares of
OCLI Common Stock will be placed on all certificates representing such shares.

         The shares of OCLI  Common  Stock to be issued in the Merger to the OCA
Shareholders  pursuant to the Merger  Agreement have been  registered  under the
Securities  Act,  thereby  allowing  such  shares  to be freely  traded  without
restriction  by persons who 



                                       43
<PAGE>

are not deemed to be  "affiliates,"  as that term is  defined in the  Securities
Act, of OCLI or of OCA. Certain officers,  directors and principal  Shareholders
of OCA may be deemed to be affiliates of OCA and thus "underwriters"  within the
meaning of Rule 145 under the  Securities  Act. Such persons will not be able to
resell the OCLI Common Stock  received by them in the Merger except  pursuant to
an effective  registration  statement  under the  Securities  Act or pursuant to
another  applicable  exemption  therefrom.  All  persons who may be deemed to be
affiliates  should carefully  consider the limitations  imposed by Rules 144 and
145 under the  Securities  Act prior to  effecting  resales  of the OCLI  Common
Stock.

Termination, Amendments and Expenses

         The Merger  Agreement  may be  terminated  and the Merger  contemplated
thereby  abandoned  at any time prior to the  consummation  of the Merger by the
mutual  consent of OCLI and OCA. The Merger  Agreement may be terminated by OCLI
or OCA acting alone if any of the conditions  precedent to their  obligations to
consummate the Merger have not been met or waived. The Merger Agreement may also
be  terminated  by OCLI or OCA acting  alone if (i) there shall be an order of a
court in effect preventing consummation of the Merger or (ii) there shall be any
action taken, or any statute,  rule,  regulation or order enacted,  promulgated,
issued or deemed applicable to the Merger,  by a governmental  entity that would
make  consummation of the Merger illegal;  or by OCLI or OCA if the Shareholders
disapprove the Merger or if the Closing does not occur by September 30, 1996.

         In the event that the Merger is terminated in accordance with the terms
of the Merger  Agreement,  each party will be responsible for the costs incurred
by it in connection with the transactions contemplated by the Merger Agreement.

Certain Effects of the Merger

         Upon consummation of the Merger, the holders of OCA Common Stock (other
holders  of shares  with  respect  to which  statutory  dissenters'  rights  are
perfected)  will receive an equity interest in a larger  diversified  company of
which OCA will be a small part. OCLI will continue to be subject to the periodic
reporting  requirements  of the  Exchange  Act and,  under  current  regulations
promulgated  thereunder,  will continue to furnish information to the Commission
so long as any securities of OCLI are listed on a national  securities  exchange
or held of record by at least  300  holders.  See  "AVAILABLE  INFORMATION"  and
"INCORPORATION  OF CERTAIN  DOCUMENTS BY  REFERENCE." It is a condition to OCA's
and OCLI's obligations under the Merger Agreement that the shares of OCLI Common
Stock to be  issued in  


                                       44
<PAGE>


connection with the Merger be listed on the Nasdaq  National Market System.  See
"THE MERGER -- Conditions to Consummation of the Merger."

         The OCA  Common  Stock is not  presently,  and  will  not be after  the
Merger, listed or traded in any established market.

         It is expected that,  following the Merger, the business and operations
of OCA will be continued by OCLI in substantially the same manner as it has been
operating. However, OCLI will continue to evaluate OCA's business and operations
following the Merger and will make such changes as are deemed appropriate.

         Once the Merger is consummated,  the holders of OCA Common Stock (other
than  Perkin-Elmer  and  holders  of  shares  with  respect  to which  statutory
dissenters' rights are perfected) will exchange their shares of OCA Common Stock
for OCLI  Common  Stock.  The rights of OCA  Shareholders,  which are  presently
governed by Massachusetts law and by the Articles of Organization and By-Laws of
OCA,  will be governed by Delaware law and the Amended and Restated  Certificate
of Incorporation and By-Laws of OCLI.  Certain  differences in the rights of OCA
Shareholders  will arise as a result of this change in governing  law as well as
from  distinctions  between the Articles of Organization  and By-Laws of OCA and
the Amended and Restated  Certificate of Incorporation and By-Laws of OCLI. "THE
MERGER -- Certain Effects of the Merger" and "COMPARISON OF RIGHTS OF HOLDERS OF
OCLI COMMON STOCK AND OCA COMMON STOCK."

Interests of Certain Persons in the Merger

         Shareholders should be aware that certain officers and directors of OCA
have interests, described below, which may present them with potential conflicts
of interest in connection with the transaction.

         Upon  consummation  of the  Merger,  all  members  of  OCA's  Board  of
Directors will resign,  and OCLI intends to name Herbert M. Dwight,  Jr., Donald
A. Johnson and Joseph C. Zils to OCA's Board.  OCLI expects Mr.  Dwight,  who is
Chairman  and  President  of OCLI,  to serve as  Chairman of OCA's  Board.  OCLI
currently intends that certain of the existing officers of OCA will retain their
offices after the Effective  Date,  but may appoint  additional  officers of OCA
from time to time.

         OCLI does not presently intend to change the base cash  compensation of
OCA's management. As of the date of this Proxy Statement/Prospectus, whether the
changes  described  above  will have the effect of  enhancing  or  reducing  the
overall compensation of 




                                       45
<PAGE>

OCA's  management  cannot  be  determined.  See  "OCLI  AND OCA  MANAGEMENTS  --
Executive Officers and Directors of OCA."

         It is not anticipated  that the directors of OCA will receive  separate
compensation for serving in such capacities.

Certain Employee Benefits Matters

         OCLI  currently  intends to maintain all material OCA employee  benefit
plans or programs  without  significant  modification  after the Effective Date.
However,  OCLI has reserved  the right to modify or  terminate  any such benefit
plans or programs,  including those described above, at any time or from time to
time after the Effective Date.

                        RIGHTS OF DISSENTING SHAREHOLDERS

         The rights of  holders of shares of OCA Common  Stock who object to the
Merger  are  governed  by  Sections  86  to  98 of  the  Massachusetts  Business
Corporation Law. The following is a summary of the applicable  provisions and is
not intended to be a complete  statement of such  provisions and is qualified in
its  entirety by  reference  to the full text of Sections 86 to 98, which is set
forth as APPENDIX I.

A SHAREHOLDER WHO ELECTS TO EXERCISE DISSENTERS' RIGHTS SHOULD MAIL OR OTHERWISE
DELIVER HIS WRITTEN NOTICE TO OPTICAL  CORPORATION OF AMERICA,  170 LOCKE DRIVE,
MARLBOROUGH, MA 01752, ATTENTION: CLERK.

         Once a  Shareholder  who proposes to claim his  statutory  rights to an
appraisal of the "fair value" of his shares of OCA Common Stock has given notice
to OCA as provided above and does not vote in favor of the Merger at the Special
Meeting,  the  following  steps must occur (with  careful  attention to the time
limits  imposed by the statute) for such  dissenting  Shareholder to perfect his
rights  to be paid the  "fair  value"  of his  shares:  (1) the  Merger  must be
approved by the required vote of the other  Shareholders  of OCA; (2) within ten
days after the  Effective  Date of the  Merger,  OCA must give  notice  that the
Merger has become  effective to each  Shareholder  from whom it received written
notice of his election to dissent and demand  payment for his shares and who did
not vote in favor of the Merger;  (3) within  twenty days of the date OCA mailed
such notice,  the dissenting  Shareholder  must submit his written demand to OCA
for payment of the "fair  value" of his shares;  (4) within a further  period of
thirty  days  (following  the  close of such  twenty  day  period),  OCA and the
dissenting  Shareholder

must  attempt to agree on the "fair  value" of his shares  and, if they do, such
payment may be made by OCA; (5) if no  agreement  is reached,  either OCA or the
dissenting  Shareholder has a further period of four months (following the close
of such  thirty day  period ), in which to  commence  an action in the  Superior
Court for Middlesex  County of the  Commonwealth of  Massachusetts,  demanding a
determination  of the "fair value" of the shares of all Dissenting  Shareholders
with  whom OCA has been  unable  to  agree;  (6)  only a  single  action  may be
commenced and the parties must include OCA and all dissenting  Shareholders with
whom OCA has been unable to agree;  (7) the Superior  Court then  determines the
"fair value" of the OCA shares as of the day  preceding  the date of the vote at
the Special  Meeting,  and that value must exclude any element of value  arising
from the  expectation  or  accomplishment  of the  Merger.  Finally,  upon  such
determination of value, OCA makes payment to the dissenting  Shareholder for his
shares.

                       COMPARISON OF RIGHTS OF HOLDERS OF
                     OCLI COMMON STOCK AND OCA COMMON STOCK

         The  rights of the OCA  Shareholders  are  governed  by the laws of the
Commonwealth of Massachusetts,  including the Massachusetts Business Corporation
Law (the "Massachusetts Law"), and by OCA's Articles of Organization, as amended
(the "OCA Articles"),  and OCA's By-Laws,  as amended (the "OCA By-Laws").  Upon
consummation of the Merger,  the OCA  Shareholders  will become  stockholders of
OCLI and their rights as stockholders  and the internal  affairs of OCLI will be
governed by the laws of the State of Delaware, including the General Corporation
Law of the State of Delaware (the  "Delaware  Law"),  and by OCLI's  Amended and
Restated  Certificate  of  Incorporation  (the "OCLI  Certificate"),  and OCLI's
By-Laws (the "OCLI  By-Laws"),  which differ in certain  material  respects from
Massachusetts  Law, the OCA Articles  and the OCA  By-Laws.  The  following is a
summary of certain differences  between the rights of OCA Shareholders  compared
with those of OCLI Stockholders.

         The following summary does not purport to be a complete  description of
the rights of  Shareholders  of OCA or the rights of  Stockholders  of OCLI or a
comprehensive  comparison  of such  rights,  and is qualified in its entirety by
reference to the governing law, to the OCLI  Certificate  and By-Laws and to the
OCA  Articles  and  By-Laws,  to  which  Shareholders  are  referred.  For  more
information  regarding reviewing or obtaining a copy of either company's charter
documents or by-laws, see "AVAILABLE INFORMATION."

Amendment of Charter and By-Laws

         Section 242 of the Delaware Law provides  that  stockholders  may amend
their   corporation's   certificate  of  incorporation  if  a  majority  of  the
outstanding  stock entitled to vote thereon,  and a majority of the  outstanding
stock of each class entitled to vote thereon as a class, has been voted in favor
of the  amendment.  The Delaware Law also provides that after a corporation  has
received any payment for its stock, the power to adopt,  amend or repeal by-laws
resides with the  stockholders  entitled to vote. A  corporation  may,  however,
grant to its board of directors in its certificate of  incorporation  concurrent
power to adopt, amend or repeal by-laws.

         Under  Massachusetts  Law,  amendments to a  corporation's  articles of
organization  relating to changes in capital or its  corporate  name require the
vote of at least a majority of each class of stock  outstanding  and entitled to
vote thereon.  Amendments  relating to other matters  require a vote of at least
two-thirds of each class outstanding and entitled to vote thereon; provided that
(i) the articles of organization or by-laws may provide for a greater proportion
and (ii) the articles of  organization  may provide for a lesser  proportion but
not less than a majority of the outstanding shares of each class.  Section 17 of
the  Massachusetts  Law provides that the  stockholders  have the power to make,
amend or repeal  by-laws and, if authorized in the articles of  organization  of
the corporation,  the by-laws may provide that directors may also make, amend or
repeal by-laws,  except with respect to any provision  thereof which by law, the
articles of organization or the by-laws requires action by the stockholders. Any
by-law adopted by the directors of the corporation may be amended or repealed by
the  stockholders.  In the event the directors make, amend or repeal any by-law,
notice of such action stating the substance of the change to the by-laws must be
given to all stockholders  entitled to vote on by-law  amendments not later than
the time of the giving of notice of the meeting of  stockholders  next following
the action by the directors.

         OCLI. OCLI's Certificate expressly provides that the Board of Directors
is authorized to adopt, repeal, alter, amend or rescind OCLI's By-Laws.

         OCA.  OCA's Articles  expressly  provide that the Board of Directors is
authorized to adopt, repeal, alter, amend or rescind OCA's By-Laws.

Certain Actions Requiring Supermajority Votes

         Both  Delaware Law and  Massachusetts  Law set certain  minimum  voting
requirements for selected  corporate  actions that may be changed by appropriate


                                       48
<PAGE>

provisions contained in a corporation's  certificate of incorporation,  articles
of organization and/or by-laws.

         OCLI. Under the OCLI  Certificate,  any of the following  actions shall
require the prior  approval  of not less than the  indicated  percentage  of the
voting power of the outstanding  shares of each class or series entitled to vote
thereon, notwithstanding that applicable law would otherwise permit such actions
with the  approval of a lesser  percentage:  (i)  removal of a director  without
cause,  pursuant to Section  141(k) of the Delaware Law: 90%; (ii) approval of a
merger or consolidation, pursuant to Subchapter IX of the Delaware Law: 66 2/3%.
The principal terms of a merger or consolidation may, however,  be approved by a
majority of the outstanding  shares of each class of the  corporation,  provided
the reorganization  shall have been approved by all authorized directors when no
vacancies exist on the Board pursuant to Section 251 of the Delaware Law.

         OCA.  OCA's  Articles  contain no provision  which  changes the minimum
voting requirements established by the Massachusetts Business Corporation Law.

Board of Directors

         Under both Delaware Law and Massachusetts Law, a corporation's board of
directors must consist of one or more individuals,  with the number fixed by (or
in the manner  provided  in) the  corporation's  by-laws or its  certificate  of
incorporation or articles of organization, respectively.

         OCLI.  OCLI's  By-Laws  state  that the  Board  shall  consist  of five
directors,  until  changed by an  amendment  of the By-Laws  duly adopted by the
Board of Directors or by the Stockholders.

         OCA. OCA's By-Laws state that the Board shall consist of such number of
directors as shall be fixed by a vote of the  Shareholders  at an Annual Meeting
thereof or Special  Meeting  called and held in lieu thereof,  provided that the
number  of  directors  shall  not be  less  than  three  unless  the  number  of
Shareholders  is less than  three,  in which event the number of  directors  may
equal the number of Shareholders.


                                       49
<PAGE>

Removal of Directors

         Delaware  Law permits any  director or the entire board of directors to
be removed,  with or without cause,  by the vote of the holders of a majority of
the shares entitled to vote.  Directors of a corporation with a classified board
of directors,  however,  can be removed only for cause unless the certificate of
incorporation provides otherwise.

         Under  Section 51 of the  Massachusetts  Law,  unless the  articles  of
organization or by-laws provide  otherwise,  (i) directors and officers selected
by  stockholders  may be removed from their  respective  offices with or without
cause by the vote of the holders of a majority of the shares entitled to vote in
the election of directors or such  officers,  as the case may be,  provided that
the  directors of a class  elected by a  particular  class of  stockholders  and
officers  elected by a particular  class of stockholders  may be removed only by
the vote of the holders of a majority of the shares of the  particular  class of
stockholders entitled to vote for the election of such directors or officers, as
the case may be; (ii)  officers  elected or  appointed by the  directors  may be
removed  from their  respective  offices,  with or without  cause,  by vote of a
majority of the directors then in office; and (iii) any director and any officer
elected by the  stockholders,  may be removed from office for cause by vote of a
majority of the directors  then in office.  A director or officer may be removed
for cause only after reasonable notice and an opportunity to be heard before the
body proposing to remove such director or officer.

         OCLI.  OCLI's  By-Laws  provide  that any  director may be removed from
office for cause only by the affirmative  vote of the holders of at least eighty
percent  (80%) of the combined  voting power of the then  outstanding  shares of
stock entitled to vote generally in the election of directors,  voting  together
as a single  class at an  annual  or  special  meeting  of  stockholders  of the
corporation  called for such purpose.  Under the OCLI Certificate,  removal of a
director  without  cause,  pursuant to Section  141(k) of the Delaware Law would
require a 90% vote,  with such action  requiring the prior  approval of not less
than the indicated  percentage of the voting power of the outstanding  shares of
each class or series entitled to vote thereon,  notwithstanding  that applicable
law would otherwise permit such action with the approval of a lesser percentage.

         OCA.  OCA's By-Laws  provide that a director may be removed from office
(i) with or without  cause by vote of the holders of a majority of the shares of
stock  entitled  to vote in the  election of  directors,  or (ii) for cause by a
majority of the  directors  then in office.  A director may be removed for cause
only after  reasonable  notice and an  opportunity  to be heard  before the body
proposing removal.

Special Meeting of the Stockholders

         Under both  Delaware Law and  Massachusetts  Law,  special  meetings of
stockholders may be called by the board of directors and by such other person or
persons authorized to do so by the corporation's certificate of incorporation or
articles of organization or by-laws. Under Delaware Law, if an annual meeting is
not held  within 30 days of the date  designated  for such a meeting,  or is not
held for a period of 13 months after the last annual meeting, the Delaware Court
of Chancery may summarily order a meeting to be held upon the application of any
stockholder or director.

         Under  Massachusetts Law,  stockholders in case none of the officers is
able and willing to call a special  meeting,  the  supreme  judicial or superior
court,  upon  application of one or more  stockholders  who hold at least 10% in
interest,  of the capital stock entitled to vote thereat,  has  jurisdiction  to
authorize  one or more of such  stockholders  to call a meeting  by giving  such
notice as is required by law.

         OCLI. Pursuant to OCLI's By-Laws,  special meetings of the stockholders
may be  called  by  either  (i) the  Chairman,  if  there  be one,  or (ii)  the
President,  and shall be called by any such officer at the request in writing of
a majority of the Board of Directors.

         OCA. OCA's By-Laws provide that special meetings of stockholders may be
called by the Board of Directors, by the Chairman or by the President.  They may
also be called by the Clerk,  or in case of the death,  absence,  incapacity  or
refusal  of the Clerk,  by any other  officer  of OCA,  upon  receipt of written
application  of one or more  stockholders  who hold at least 10% of the  capital
stock entitled to vote at a meeting of stockholders.

Actions by Stockholders Without a Meeting

         Unless a  corporation's  certificate  of  incorporation  or articles of
organization  provide  otherwise,  Delaware Law and  Massachusetts Law allow any
action  required  to be taken,  or which may be taken,  at an annual or  special
meeting of  stockholders  to be taken without prior notice and without a vote so
long as the written consent of stockholders is obtained.

         OCLI.  The OCLI  Certificate  provides  that "Any  action  required  or
permitted to be taken by the stockholders of the Corporation must be effected at
a duly called annual or special  meeting of such holders and may not be effected
by any consent in writing by such holders  unless such consent in writing  shall
be signed  either by the holders of 80% of the shares  entitled to vote thereon,
or by 





                                       51
<PAGE>

the holders of the majority of the shares  entitled to vote  thereon,  or by the
holders of the majority of the shares entitled to vote thereon where such action
has been approved by all  authorized  directors  when no vacancies  exist on the
Board."

         OCA. The OCA By-Laws  provide that any action  required or permitted to
be taken by the  Shareholders may be taken without a meeting if all Shareholders
entitled to vote on the matter  consent to the action in writing and the written
consent is filed with the records of the meetings of Shareholders.

Cumulative Voting

         Under Delaware Law,  cumulative  voting in the election of directors is
available only if specifically  provided for in a  corporation's  certificate of
incorporation.

         Under  Massachusetts  Law, it is generally  understood  that cumulative
voting is not permitted in Massachusetts corporations although Massachusetts Law
does not expressly prohibit it.

         Neither  the  OCLI   Certificate  nor  the  OCA  Articles  provide  for
cumulative voting.

Vote Required for Certain Mergers and Consolidations

         Delaware  Law,  insofar as it relates  to mergers  and other  corporate
reorganizations,  does not differ  substantially  from  Massachusetts  Law. Both
Massachusetts  Law and  Delaware Law provide for a  stockholder  vote (except as
indicated  below) of both the  acquiring  and  acquired  corporation  to approve
mergers.  In addition,  while both  Massachusetts Law and Delaware Law require a
stockholder vote of the selling corporation for the sale by a corporation of all
or substantially all of its assets,  Massachusetts Law requires such a vote only
if the sale is not in the regular course of business. Both Massachusetts Law and
Delaware  Law provide for a  stockholder  vote to approve the  dissolution  of a
corporation.

         Both  Massachusetts  Law and Delaware Law do not require a  stockholder
vote of the surviving  corporation in a merger provided  certain  conditions are
satisfied.  Massachusetts Law requires that after the merger (i) the articles of
organization  of the  surviving  corporation  will not differ from its  articles
before  the  merger  (except  for  amendments   authorized  absent   shareholder
approval);  and (ii) the shares to be  delivered 



                                       52
<PAGE>

pursuant  to the  agreement  of merger do not  exceed  15% of the  shares of the
Issuer of the same class  outstanding  immediately  and to the effective date of
the  merger;  and  (iii)  the issue of such  shares  by the  directors  has been
authorized in accordance with Massachusetts Law. Delaware Law does not require a
shareholder  vote of the  surviving  corporation  in a merger if (i) the  merger
agreement does not amend the existing  certificate of  incorporation;  (ii) each
outstanding or treasury share of the surviving  corporation before the merger is
unchanged  after the merger;  and (iii) the number of shares to be issued by the
surviving  corporation  in  the  merger  does  not  exceed  20%  of  the  shares
outstanding immediately prior to such issuance.

         Both  Massachusetts  Law and Delaware Law do not require a  stockholder
vote  for  certain  "short-form  mergers"  between  a  parent  company  and  its
subsidiary.  Both Massachusetts Law and Delaware Law require that the subsidiary
be 90% owned by the parent.

Class Vote for Certain Reorganizations

         Generally,  neither  Massachusetts  Law nor Delaware Law require  class
voting.  However,  Massachusetts  Law provides  that class or series voting as a
separate voting group is required (i) on a plan of merger if the plan contains a
provision  which,  if  contained  in a proposed  amendment  to the  articles  of
organization,  would  entitle  the class or series to vote as a separate  voting
group on the  proposed  amendment;  or (ii) on a plan of share  exchange  if the
shares of such class or series of shares are to be converted or exchanged  under
such plan or if the plan  contains  any  provisions  which,  if  contained  in a
proposed  amendment  to articles  of  organization,  would  entitle the class or
series to vote as a separate  voting group on the proposed  amendment.  Delaware
Law requires  class voting  where the  transaction  involves an amendment to the
certificate  of  incorporation  which would  increase or decrease the  aggregate
number of authorized shares of the class,  increase or decrease the par value of
the shares of the class,  or alter or change the powers,  preferences or special
rights of the shares of the class so as to affect them adversely.

Dissenters' Rights

         Under both Massachusetts Law and Delaware Law, a dissenting stockholder
of  a  corporation   participating  in  certain   transactions,   under  varying
circumstances,  may  receive  cash in the amount of the fair value of his or her
shares  (as  determined  by a  court)  in  lieu of the  consideration  otherwise
receivable in any such transaction.  Under Delaware Law,  dissenters' rights are
not available  with respect to a plan of merger or share  exchange or a proposed
sale or exchange of property to holders of shares of any class or series  which,
on the record date fixed to determine the  stockholders  entitled to vote at the


                                       53
<PAGE>

meeting of  stockholders  at which such action is to be acted upon or to consent
to any such  action  without a  meeting,  were  either  (i) listed on a national
securities  exchange or  designated as a national  market system  security on an
interdealer  quotation system by the National Association of Securities Dealers,
Inc., or (ii) held of record by more than 2,000 stockholders. In addition, under
Delaware  Law,  dissenters'  rights are not available for any shares of stock of
the  constituent  corporation  surviving  a merger if the merger did not require
stockholder approval of the surviving  corporation.  However, they are available
for the shares of stock of the  constituent  corporation  which are not owned by
the parent  corporation  merging  into itself a  subsidiary  of which is owns at
least 90% of the shares of each class of stock outstanding.

         Massachusetts Law also provides  dissenters'  rights in connection with
(i) sales of substantially all of a corporation's assets, (ii) amendments to the
articles of organization that may adversely affect certain rights of preferences
of  stockholders  and (iii)  control-share  acquisitions.  Delaware Law does not
provide dissenters' rights with respect to any sale of assets,  reclassification
of stock or amendment to the certificate of incorporation.

Anti-Takeover Statutes

         OCLI.  OCLI is subject to Section  203 of the  Delaware  Law  ("Section
203"),  which regulates large  accumulations of shares,  including those made by
tender  offers.  Section  203 may have the  effect of  significantly  delaying a
purchaser's  ability to acquire the entire interest in OCLI if such  acquisition
is not approved by OCLI's Board of Directors.  In general,  Section 203 prevents
an "Interested Stockholder" (defined generally as a person with 15% or more of a
corporation's   outstanding   voting   stock)  from   engaging  in  a  "Business
Combination"  (defined  below)  with a  Delaware  corporation  for  three  years
following the date such person became an Interested Stockholder. For purposes of
Section  203,  the  term  "Business   Combination"   includes  sales,  or  other
dispositions  to the Interested  Stockholder  (except  proportionately  with the
corporation's  other  stockholders) of assets of the corporation or a subsidiary
equal  to 10% or  more  of  the  aggregate  market  value  of the  corporation's
consolidated  assets or its outstanding  stock;  the issuance or transfer by the
corporation or a subsidiary of stock of the  corporation  or such  subsidiary to
the Interested  Stockholder (except for transfers in a conversion or exchange or
a pro rata  distribution or certain other  transactions,  none of which increase
the Interested  Stockholder's  proportionate ownership of any class or series of
the  corporation's  or such  subsidiary's  stock);  or receipt by the Interested
Stockholder (except  proportionately as a stockholder),  directly or indirectly,
of any loans, advances, guarantees, pledges or other financial benefits provided
by or through the corporation or a subsidiary.



                                       54
<PAGE>

         The three-year  moratorium imposed on Business  Combinations by Section
203 does not apply if: (a) prior to the date on which such  stockholder  becomes
an Interested  Stockholder  the Board of Directors  approves either the Business
Combination  or the  transaction  which  resulted  in  the  person  becoming  an
Interested  Stockholder;   (b)  the  Interested  Stockholder  owns  85%  of  the
corporation's  voting stock upon  consummation of the transaction which made him
or her an Interested  Stockholder  (excluding  from the 85%  calculation  shares
owned by directors  who are also officers of the target  corporation  and shares
held  by  employee  stock  plans  which  do  not  permit   employees  to  decide
confidentially whether to accept a tender or exchange offer); or (c) on or after
the date such person becomes an Interested  Stockholder,  the Board approves the
Business Combination and it is also approved at a stockholder meeting by holders
of two-thirds of the voting stock not owned by the Interested Stockholder.

         Under Section 203, the  restrictions  described  above do not apply if,
among other things,  the  corporation's  original  certificate of  incorporation
contains a provision  expressly  electing  not to be  governed  by Section  203.
OCLI's Certificate does not contain such a provision. OCLI could, at its option,
exclude  itself from the coverage of Section 203 by amending its  Certificate or
By-Laws  at any time to exempt  itself  from  coverage;  but a by-law or charter
amendment  may not  become  effective  for a period of twelve  months  after the
amendment is adopted.  The restrictions  described above do not apply to certain
Business  Combinations  proposed  by an  Interested  Stockholder  following  the
announcement  or  notification  of one  of  certain  extraordinary  transactions
involving  the  corporation  and  a  person  who  had  not  been  an  Interested
Stockholder  during  the  previous  three  years  or who  became  an  Interested
Stockholder with the approval of a majority of the corporation's directors.

         Section 203 is currently  under  challenge  in lawsuits  arising out of
ongoing  takeover  disputes,  and it is not yet clear whether and to what extent
its constitutionality  will be upheld by the courts.  Although the United States
District  Court of Delaware has  consistently  upheld  Section 203, the Delaware
Supreme Court has not yet considered  the issue.  OCLI believes that, so long as
the  enforceability  of Section 203 is upheld,  Section 203 will  encourage  any
potential  acquirer  to  negotiate  with  OCLI's  Board  of  Directors  prior to
effecting  any  takeover  attempt.  Section  203 also  should have the effect of
limiting the ability of a potential  acquirer to make a two-tiered  bid in which
all of OCLI's stockholders would not be treated equally. Section 203 should also
discourage certain potential  acquirers unwilling to comply with its provisions.
Stockholders should note that the application of Section 203 to OCLI will confer
upon the Board the power to reject a proposed Business Combination,  even though
a potential  acquirer may be offering a  substantial  premium for OCLI's  shares
over the then-current market price.



                                       55
<PAGE>

         OCA.  Massachusetts  Law  prohibits  a  corporation  with  200 or  more
stockholders   from  engaging  in  a  "Business   Combination"  (as  defined  in
Massachusetts  Law) with an  "Interested  Stockholder"  (defined  generally as a
person who,  together with  affiliates and  associates,  owns 5% or more of such
corporation's  outstanding voting stock, or as an affiliate or associate of such
corporation  who,  together with affiliates and associates,  owned 5% or more of
such  corporation's  outstanding voting stock at any time within the immediately
preceding  three-year  period)  for three years  following  the date such person
became an Interested Stockholder. The provision is not applicable when (i) prior
to the date the  stockholder  became  an  Interested  Stockholder,  the board of
directors of the  corporation  approved  either the Business  Combination or the
transaction that resulted in the stockholder becoming an Interested Stockholder,
(ii) upon  consummation  of the  transaction  that  resulted in the  stockholder
becoming an Interested  Stockholder,  such Interested Stockholder owned at least
90% of the outstanding  voting stock of the  corporation,  not including  shares
owned by directors who are also officers and by certain  employee stock plans or
(iii) on or  subsequent  to the  date  the  stockholder  becomes  an  Interested
Stockholder,  the Business  Combination is approved by the board of directors of
the corporation and authorized at a meeting of stockholders,  and not by written
consent,  by the affirmative  vote of the holders of at least  two-thirds of the
outstanding voting stock entitled to vote thereon, excluding shares owned by the
Interested  Stockholder.  These restrictions  generally do not apply to Business
Combinations with an Interested  Stockholder that are proposed subsequent to the
public announcement of, and prior to the consummation or abandonment of, certain
mergers,  sales of a majority of a corporation's assets or tender offers for 50%
or  more  of  a  corporation's   voting  stock.  The  Massachusetts  Law  allows
corporations  to elect not to be  subject  to the  preceding  provisions  of the
Massachusetts Law.

Stockholder Rights Plan

         OCLI. In November  1987,  OCLI adopted a Stockholder  Rights Plan which
expires in  November  1997,  under which OCLI  declared a dividend of  preferred
stock purchase rights which only become exercisable,  if not redeemed,  ten days
after a person or group has acquired  20% or more of OCLI's  Common Stock or the
announcement of a tender offer which would result in a person or group acquiring
30% or more of OCLI's Common Stock. Under certain circumstances, the plan allows
stockholders,  other than the  acquiring  person or group,  to  purchase  OCLI's
Common Stock or the common stock of the acquirer  having a market value of twice
the exercise price.


                                       56
<PAGE>


         These rights, commonly referred to as a "poison pill," may have certain
anti-takeover  effects.  See  "DESCRIPTION  OF OCLI'S CAPITAL STOCK  --Preferred
Stock and Stockholder Rights Plan."

          OCA.  OCA does not have a comparable stockholder rights agreement.

Preemptive Rights

         OCLI. Delaware Law generally permits a Delaware  corporation to provide
its  stockholders  with the  preemptive  right to subscribe to capital  stock or
securities convertible into stock in its certificate of incorporation.  The OCLI
Certificate does not provide for preemptive rights.

         OCA.  Massachusetts  Law generally  provides that no stockholder  shall
have any  preemptive  right to acquire  stock of the  corporation  except to the
extent  provided in the articles of  organization  or in a by-law adopted by and
subject to amendment only by the stockholders.

Dividends

         OCLI.  Delaware  Law  provides  that a  corporation,  unless  otherwise
restricted by its  certificate of  incorporation,  may declare and pay dividends
out of surplus,  or if no surplus exists,  out of net profit for the fiscal year
in which the dividend is declared or the preceding  fiscal year  (provided  that
the amount of capital of the  corporation  following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding  shares of all classes having  preference upon the
distribution of assets). Additionally, Delaware Law provides that, in general, a
corporation may redeem or repurchase its shares only out of surplus.

         OCA.  Massachusetts Law describes no special sources for distributions.
It  specifies  instead  the  liabilities  which  can  result  from  an  improper
distribution  by a  corporation,  both  for  the  directors  who  authorize  the
distribution  and the  stockholders  who  receive  it.  Generally,  an  improper
distribution  is one made when a  corporation  is insolvent or would be rendered
insolvent by part or all of the distribution. To the extent of the damage to the
corporation,  the directors who authorize it and the stockholders who receive it
are jointly and severally liable to the corporation.

Limitation on Directors' Liability; Indemnification

         In  general,  Delaware  Law  contains  more  extensive  indemnification
provisions than does  Massachusetts Law. Under Delaware Law, the corporation may
include in its certificate of incorporation a provision  eliminating or limiting
the personal  liability of a director to the corporation or its stockholders for
monetary  damages for breach of fiduciary duty as a director under a broad range
of circumstances.  OCLI's Certificate  includes a provision which eliminates the
directors' liability for monetary damages for a breach of the directors' duty of
care to OCLI or its stockholders (the "Delaware Duty of Care  Provision").  As a
result of the  Delaware  Duty of Care  Provision,  no  director  of OCLI will be
liable for monetary damages for negligence or gross  negligence  occurring after
the Merger.  Each director will remain  personally liable to OCLI for failure to
act in good  faith or to comply  with his or her duty of  loyalty  to OCLI.  The
directors  will  continue to be subject to  equitable  remedies,  although  such
remedies in some  circumstances  may not be available as a practical  matter. In
addition, under Delaware Law, each director will remain liable for engaging in a
transaction from which such director derives an improper personal benefit or for
engaging in intentional  misconduct or a knowing violation of law. Moreover, the
Delaware Duty of Care  Provision  also will not limit  directors'  liability for
violations of the federal securities laws. With regard to directors who are also
officers of OCLI,  these persons  would be insulated  from  liability  only with
respect to their conduct as directors and would not be insulated  from liability
for acts or omissions in their capacity as officers.

         Section 67 of the  Massachusetts Law provides that  indemnification  of
directors,  officers,  employees and other agents of a corporation,  and persons
who serve at its request as  directors,  officers,  employees or other agents of
another  organization,  may be provided by it to whatever extent specified in or
authorized  by (i) the articles of  organization,  (ii) a by-law  adopted by the
stockholder  or (iii) a vote  adopted by the holders of a majority of the shares
of stock  entitled to vote on the election of directors.  OCA's By-Laws  provide
for indemnification of its directors,  officers and employees to the full extent
permitted by the  Massachusetts  Law.  Section  13(b) of the  Massachusetts  Law
allows a corporation to include in its articles of organization a provision that
limits or eliminates the personal  liability of directors to the corporation and
its  Shareholders  for  monetary  damages  for  breach  of  fiduciary  duty as a
director.  OCA's Articles include provisions  eliminating the personal liability
of OCA's  directors  for  monetary  damages  resulting  from  breaches  of their
fiduciary  duty except (i) for any breach of the  director's  duty of loyalty to
OCA or its  Shareholders,  (ii) for acts or omissions not in good faith or which
involve  intentional  misconduct  or a knowing  violation  of law,  (iii)  under
Sections 61 and 62 of


                                       58
<PAGE>

the Massachusetts  Law, or any amendatory or successor  provisions  thereto,  or
(iv) with respect to any transaction from which the director derived an improper
personal benefit.

         Delaware Law  authorizes  the  corporation  to indemnify  any person or
party to any threatened,  pending or completed action, suit or proceeding, other
than an action by or in the right of the corporation, by reason of the fact that
he or  she  was  serving  as a  director,  officer,  employee  or  agent  of the
corporation  or is or was  serving at the request of the  corporation  at a like
position of another corporation (the "Indemnitee") against expenses,  judgments,
fines and  amounts  paid in  settlement  actually  and  reasonably  incurred  in
connection  with such  action  if the  Indemnitee  acted in good  faith and in a
manner he or she  reasonably  believed  to be in, or not  opposed  to,  the best
interests of the  corporation  (or,  with respect to a criminal  action,  had no
reasonable cause to believe his or her conduct was unlawful).  Massachusetts Law
contains a similar  provision which authorizes the corporation to indemnify such
person against  liability  incurred in connection  with such action if he or she
acted with the same requisite conduct.

         Delaware Law also  authorizes the  corporation to indemnify such person
in  connection  with any  threatened,  pending or completed  action by or in the
right of the  corporation  to procure a judgment in its favor  against  expenses
actually and reasonably incurred by him or her in connection with the defense or
settlement of such action if he or she acted with the requisite conduct.

         In   Massachusetts,   the   absence   of  an  express   provision   for
indemnification  does not  limit  any  right  of  indemnification  which  exists
independently  of  the  Massachusetts   Law.  Thus,  the  stockholders   control
indemnification  of  personnel  selected  by  them  and  the  directors  control
indemnification of all other personnel unless such indemnification is restricted
by the corporation's articles of organization or by-laws.

         Under both  Massachusetts  Law and Delaware Law, the  corporation  must
provide for  indemnification  on a case by case basis after a determination that
the  Indemnitee  met the applicable  standard of conduct.  Similarly,  both laws
provide  that the  determination  is made in the first  instance by the board of
directors by a majority  vote of a quorum  consisting  of directors who were not
parties to such proceeding.  However,  under Massachusetts Law, if such a quorum
is not obtainable,  or, even if obtainable if the board of directors  (including
directors  who  are  parties)  so  directs,  the  determination  must be made by
majority  vote  of a  committee  duly  designated  by  the  board  of  directors
consisting  solely  of two or more  directors  not at the  time  parties  to the
proceeding,  by independent legal counsel or finally by the stockholders.  Under
Delaware Law, if a quorum is not obtainable,  or, even if obtainable a quorum of
disinterested   directors  so  


                                       59
<PAGE>

directs,  the  determination  must be made by  independent  legal  counsel  in a
written opinion or by the stockholders.

         Furthermore,  both  Massachusetts  Law and  Delaware Law provide that a
corporation may make other or further indemnification or advancement of expenses
of any of its  directors,  officers,  employees  or  agents  under  any  by-law,
agreement, vote of stockholders or disinterested directors, or otherwise both as
to action in an official  capacity  and as to action in another  capacity  while
holding such office. OCLI has indemnification  agreements with its directors and
officers that provide for the maximum indemnification allowed by law.

         OCLI's   Certificate   takes  advantage  of  the  permissive   Delaware
indemnification  laws and provides  that:  (i) OCLI is required to indemnify its
officers and  directors to the full extent  permitted by law; and (ii)  expenses
incurred in defending a civil or criminal action, suit or proceeding may be paid
by OCLI in advance of the final  disposition of such action,  suit or proceeding
upon  receipt of an  undertaking  by or on behalf of the  director or officer to
repay such amount if it shall  ultimately be determined  that he is not entitled
to be indemnified by OCLI.

         OCA's Articles contain no specific provision regarding indemnification.
OCA's  By-Laws  grant the right to  indemnification  to each  person  elected or
appointed a director, officer, employee or agent of the corporation except under
circumstances  where such  individual  shall be  determined,  as provided in the
By-Laws, not to have acted in the best interest of OCA.

Loans to Officers and Employees

         Both  Massachusetts Law and Delaware Law provide that a corporation may
make  loans to, or  guarantee  the  obligations  of, or  otherwise  assist,  its
officers and other employees and those of its subsidiaries  when such action, in
the judgment of the corporation's board of directors, may reasonably be expected
to benefit the  corporation.  However,  while  Massachusetts  Law authorizes the
corporation  to make a loan to, or guarantee  the  obligations  of, or otherwise
assist a director as well, Delaware Law applies only to those directors who also
are officers or employees of the corporation or subsidiary.



                                       60
<PAGE>

Voting By Ballot

         Under Delaware Law, each stockholder has the right to require a vote by
written  ballot for the election of directors at a  stockholder  meeting  unless
otherwise restricted as provided in the certificate of incorporation.

         There is no similar voting provision in the Massachusetts Law.

Inspection of Shareholder Lists

         Massachusetts   Law  provides  that  a  stockholder   may  inspect  the
stockholders'  list if (i) his  demand  is made in good  faith  and for a proper
purpose; (ii) he describes with reasonable  particularity his purpose; and (iii)
the  stockholders'  list is directly  connected with his purpose.  Additionally,
Massachusetts Law provides to any stockholder an absolute right of inspection of
the  stockholders'  list for a ten-day period  preceding a stockholder  meeting.
Delaware  Law  provides  to any  stockholder  of record the right to inspect the
stockholder list of the corporation for any purpose germane to the meeting for a
ten-day period preceding a stockholder meeting.

                       DESCRIPTION OF OCLI'S CAPITAL STOCK

         The authorized capital stock of OCLI as of the Record Date consisted of
30,000,000  shares of  authorized  common  stock,  $.01 par value ("OCLI  Common
Stock"),  of which  9,728,129  shares were issued and  outstanding,  and 100,000
shares of authorized  preferred stock, $.01 par value,  ("OCLI Preferred Stock")
of which 12,000 shares of 8% Series C Convertible Redeemable Preferred Stock(the
"Series C Preferred Stock") were issued and outstanding.

Common Stock

         Holders of OCLI Common  Stock are entitled to one vote per share on all
matters to be voted upon by the  stockholders.  There are no  cumulative  voting
rights.  The holders of OCLI Common Stock have no preemptive rights or rights to
convert their OCLI Common Stock into any other securities. The OCLI Common Stock
is not subject to  redemption.  Upon any  liquidation,  distribution  or sale of
assets,  dissolution or winding up of OCLI, the holders of OCLI Common Stock are
entitled  to share pro rata in the  assets of OCLI  available  for  distribution
after  provision  for the payment of creditors  and subject to the  preferential
rights of any then outstanding  OCLI Preferred Stock. The outstanding  shares of
OCLI Common Stock are fully paid and nonassessable. There are no restrictions on
transferability  contained in OCLI's  Certificate or OCLI's By-Laws.  


                                       61
<PAGE>

Subject to preferences that may be applicable to any outstanding  shares of OCLI
Preferred  Stock,  holders of OCLI Common Stock are entitled to receive  ratably
such dividends as may be declared by the Board of Directors out of funds legally
available  therefor.  The OCLI  Common  Stock is listed on the  Nasdaq  National
Market System.

         As of the Record Date, there were outstanding  9,728,129 shares of OCLI
Common Stock.  Additional  information  concerning the rights of holders of OCLI
Common Stock, is set forth under "COMPARISON OF RIGHTS OF HOLDERS OF OCLI COMMON
STOCK AND OCA COMMON STOCK."

Preferred Stock

         OCLI has authorized  100,000 shares of preferred stock, $.01 par value,
of which 10,000 shares were  designated  Series A Preferred  Stock in connection
with OCLI's  Stockholder  Rights Plan.  None of the Series A Preferred  Stock is
issued. Additionally, 15,000 shares were designated Series B Preferred Stock, of
which 8,350 shares were issued and subsequently  converted to OCLI Common Stock.
None of the Series B Preferred Stock is currently issued and outstanding.

         In  May  1995,  as  part  of the  financing  of  the  acquisition  of a
controlling interest in Flex Products, Inc., OCLI issued 12,000 shares of Series
C Preferred Stock in consideration  for $1,000 per share. The Series C Preferred
Stock is  convertible  into OCLI  Common  Stock at any time by the  holders at a
conversion  price of $10.50 per common share  (subject to  adjustment in certain
circumstances).  The Series C Preferred  Stock is redeemable by OCLI  commencing
two years from the date of issuance  (if the OCLI Common Stock is trading at $17
per share or more for any 20  consecutive  day period)  and,  after three years,
unconditionally, at 108% of the purchase price per share, declining to 100% over
four years.  The holders of the Series C Preferred Stock are entitled to receive
a cumulative  annual dividend of $80 per share,  which is payable  quarterly and
has preference to any other dividends being paid by OCLI.

         The holders of shares of Series C Preferred  Stock are not  entitled to
notice  of any  stockholders'  meetings  or to vote  on any  matter,  except  as
provided  by law or as  otherwise  specified  in the  Series C  Preferred  Stock
Certificate of Designation,  Preferences and Rights.  If, however,  dividends on
the Series C Preferred Stock are in arrears in an amount equal to four quarterly
dividends,  a default  period  would  begin in which the holders of the Series C
Preferred Stock, voting as a class, would have the right to elect the greater of
two  directors or a number of directors not less than 25% of the total number of
authorized  directors.  Such right  terminates  upon  expiration  of the default
period.  The  holders  of  the  Series  C  Preferred  Stock  are  entitled  to a
liquidation  



                                       62
<PAGE>

preference equal to $1,000 per share plus accrued and unpaid dividends. OCLI may
not create any series or class of capital  stock  ranking  prior or equal to the
Series C  Preferred  Stock  unless  the  terms of any  such  series  or class is
approved by the holders of not less than two-thirds of the outstanding shares of
Series C Preferred Stock voting separately as a class.

         Pursuant to the terms of a Stock Purchase  Agreement  entered into with
the holders of the Series C Preferred  Stock,  OCLI may not pay any dividends or
make any other  distributions  in  respect  of, or  redeem  or  repurchase  any,
securities  of OCLI to the extent  such  payments  exceed 25% of the  difference
between  (a)  aggregate  "Net  Income"  (as such  term is  defined  in the Stock
Purchase  Agreement) of OCLI after January 31, 1995 and (b) all losses  suffered
by OCLI during such period.

Stockholder Rights Plan

         OCLI. In November  1987,  OCLI adopted a Stockholder  Rights Plan which
expires in  November  1997,  under which OCLI  declared a dividend of  preferred
stock purchase rights which only become exercisable,  if not redeemed,  ten days
after a person or group has  acquired  20% or more of OCLI  Common  Stock or the
announcement of a tender offer which would result in a person or group acquiring
30% or more of OCLI Common Stock. Under certain  circumstances,  the plan allows
stockholders,  other than the acquiring person or group, to purchase OCLI Common
Stock or the common  stock of the  acquirer  having a market  value of twice the
exercise price.

               RELATIONSHIP AND TRANSACTIONS BETWEEN OCLI AND OCA


         OCLI and OCA have worked together on several projects over the past six
years. Beginning in 1990, OCLI subcontracted with OCA for the coating of missile
domes for the U.S Department of Defense. Under this arrangement,  OCA fabricated
the missile domes in its facilities in Garden Grove, California and sent them to
OCLI to be coated at it facilities in Santa Rosa. Since the initial order,  OCLI
has received  several  follow-up  orders from OCA for the coating of the missile
domes in addition to several other smaller coating  subcontracts  for which OCLI
has  received  orders  worth  approximately   $657,000  since  1992,   including
approximately $40,000 of sales after the second quarter of 1996.

         Beginning  in 1995,  OCA  subcontracted  with  OCLI for the  supply  of
optical subassemblies and optical fabrication. In fiscal 1995 OCLI placed orders
with OCA worth approximately  $75,000 and orders year-to-date in fiscal 1996 are
worth $407,000,  



                                       63
<PAGE>

including approximately $200,000 of open orders at the end of the second quarter
of 1996.

         In addition to being both  suppliers  and  customers to each other over
the last  several  years,  OCA and OCLI have both  competed  for optical  filter
business  in  the  defense,   aerospace,   medical  instrumentation  and  office
automation market segments along with other companies including, but not limited
to, Barr Associates,  Optical Filter Corporation, Varo, and Deposition Sciences,
Inc.

                                 BUSINESS OF OCA
General

         OCA  develops,  manufactures  and markets  optical and  electro-optical
products,  components  and subsystems  for a wide range of  applications  in the
medical,  telecommunication,   industrial,  scientific,  aerospace  and  defense
industries.  OCA focuses on four categories of product and related services: (1)
Optical  Filters,   (2)  Electro-Optical   Sensors  and  Cameras,   (3)  Optical
Correlators  and (4) Fiber  Optics  Communications  Devices.  OCA also  enjoys a
significant  business in optical  components  and  subsystems for commercial and
governmental markets.

Products and Services

         Optical Filters

         OCA designs, manufactures and markets optical filters which incorporate
proprietary  technology  or  multilayer  thin film  coatings.  Optical thin film
coatings  control  and  enhance  light  energy  by  altering  the  transmission,
reflection  and  absorption  of the  various  wavelengths  of light to achieve a
desired  optical  effect.  OCA has  developed  and patented a thin-film  coating
process called MicroPlasmaAE which permits OCA a distinct competitive  advantage
in providing high quality  optical  filters to customers in various  industries.
Optical filters are used as components in instruments  and systems  manufactured
by original  equipment  manufacturers,  principally  to  bio-medical  instrument
manufacturers.  OCA has steadily increased its production  capacity in this area
and has  achieved a high level of  automation.  OCA expects  that an  increasing
share of the filters which it manufactures will be used in the production of its
Fiber Optic Communication Devices.

         OCA's line of optical  filters  runs from the  ultraviolet  through the
visible and into the infrared  spectrum of light.  OCA also makes  filters which
block certain  wavelengths of light for eye-safe laser protection  devices,  and
passive intrusion  filters which detect 


                                       64
<PAGE>

heat from  bodies  approaching  a field of view and will  activate  a  switching
mechanism.  These products are often termed motion detection devices but in fact
rely on heat transmitted by a source at an infrared wavelength.  Optical filters
are produced for a highly competitive market.

         Electro-Optical Sensors and Cameras

         OCA believes  that it is  recognized  by its  customers as an important
supplier  of  lightweight   electro-optical  sensor  systems  for  airborne  and
spaceborne applications.  This recognition stems from OCA's participation in the
Brilliant  Pebbles  and  Clementine  Programs  in the late 1980s and early 1990s
sponsored by the Strategic Defense  Initiative/Ballistic Missile Division, which
allowed  OCA to enhance  its  already  strong  opto-mechanical  background  with
state-of-the-art, in-house electronics design and fabrication capabilities.

         OCA's color video  cameras set a new standard for  performance  and low
mass.  OCA plans to encourage  use of this product and  technology in both space
related and commercial applications.

         OCA's  experience with lightweight  sensors  positions it to capitalize
upon the shift from small  numbers of large,  costly  spacecraft  to much larger
numbers of small,  relatively  inexpensive  spacecraft  for both  government and
commercial  applications.  OCA  anticipates  that a substantial  fraction of its
future business can be derived from this technology base.

         Optical Correlators

         OCA has an established  reputation in the field of Optical  Processing.
Beginning in 1985, OCA became one of the original system hardware  innovators in
this field,  transforming  theoretical  analysis and  scientific  research  into
development efforts for field deployable hardware which could be used for target
recognition  and target  tracking in missile  systems.  The  fundamentals of the
technology  employ the inherent strength of optics to process an entire scene of
data  instantaneously  (at the speed of light).  Analytical  speed combined with
relatively low power and packaging requirements, yields an attractive technology
for programs which incorporate optical processing.  OCA will continue to support
government applications using optical processing for guidance and navigation and
radar imagery analysis;  in particular,  because optical processing provides the
foundation of its commercial correlator line.


                                       65
<PAGE>


         The  potential  for  commercial   applications   is  found  in  factory
automation,  security,  medical  imagery  and  remote  sensing  imagery.  OCA is
developing  solutions  for each of these  applications.  For  example,  OCA will
introduce in 1996 a commercial optical processor.  The flash 256 Optical Fourier
Processor is an entirely  new product for the image  processing  industry,  with
significant competitive implications.

         Fiber Optic Communications Devices

         OCA has recently  introduced  a new line of optical  devices for use in
the  fiber  optic   communications   market.   OCA  manufactures   four  devices
incorporating filters produced by OCA using its patented  MicroPlasma(R) coating
process.  These devices are (a) a Channel Add/Drop Filter, (b)a Tunable Bandpass
Fiber Optic Filter, (c) a 4 Channel Dense Wavelength Division Multiplexer (DWDM)
and (d) an 8 Channel Dense Wavelength Division Multiplexer (DWDM). These devices
generally  operate  in the 1530 to 1560  nanometer  (nm)  range  and are  unique
because of their ability to operate in a passive mode.

         In addition  to their  narrow  bandwidths,  their low  cross-talk  (the
result of OCA's  ability to produce 3 cavity and 5 cavity filter  designs),  low
insertion loss and durability,  these devices also  demonstrate  high wavelength
stability  and  minimal  temperature  shift  (less than .001  nm/"C  temperature
shift). This minimal shift is the result of OCA's MicroPlasma(R) process.

         OCA believes its devices are enabling technology which will accommodate
significantly  increased data transmission  over the existing  installed base of
fiber optic cable. While other DWDM devices exist which might compete with those
manufactured by OCA, to date OCA believes its devices are the most advanced, and
filter  based  devices  appear to have a technical  advantage  over  alternative
technologies.

         Optical Components and Subsystems

         OCA plays  significant  role in the design and  manufacture  of leading
edge optical products.  OCA has been selected  repeatedly by leading commercial,
scientific and defense  organizations to work cooperatively under formal teaming
agreements and strategic  alliances to develop  innovative  solutions to optical
design,  packaging  and  manufacturing  problems  for a wide  range  of  product
applications. The importance of the technologies developed during these projects
continues  to grow  with the  emergence  of the  small  satellite  industry  for
commercial  applications  such as  Earthwatch.  OCA is currently  developing the
telescope for the Earthwatch  remote sensor which is expected to provide 3 meter
resolution photographs of the earth for commercial users.

                                       66
<PAGE>

         OCA's  development  of advanced  infrared  search and track  (IRST) and
missile launch detection  systems in cooperation with  Westinghouse and Lockheed
Martin  addresses a growing  market for the  protection  and  improvement of our
nation's existing air defense capabilities.

Research and Development

         OCA focuses its research and development  activities on the development
of new proprietary products, enhancements to existing products, and enhancements
of core technologies.  OCA funds these activities from both internal sources and
external contracts.

Manufacturing

         OCA's approach is to identify and perform  internally  those  functions
which enable it to maintain  control over  critical  portions of the  production
process and which add value to its products.  At the same time, OCA's purchasing
departments  make every effort to insure that qualified  suppliers are available
for functions which are better or more  economically  performed by others.  Both
OCA's  California  and  Massachusetts  operations  have  complete,  stand  alone
capabilities  appropriate  to the  support of the  varying  requirements  of its
Business  and  customers.  Engineering,   manufacturing,   sales  and  marketing
personnel are available at both locations.

      In  California,  OCA designs,  manufactures,  costs,  assembles  and tests
electro-optical  subsystems and complex electro-optical  assemblies for customer
use in infrared, visible and ultraviolet systems. OCA's fabrication capabilities
are sophisticated and include Single Point Diamond Turning,  electroless  nickel
plating and Beryllium Hot Isostatic  Pressing,  and allow OCA to produce compact
and lightweight subsystems without the degree of subcontracting required by most
of its competitors.

         In  Massachusetts,  OCA is a leading provider of thin film products for
OEM customers.  OCA's state-of-the-art  coatings,  combined with its proprietary
automation  processes,  assure a solid market presence.  Additional  capacity is
being added to meet the  forecasted  demand for OCA's new  products in the fiber
optic communications marketplace.  The enabling technology is the optical filter
and OCA  produces  filters  routinely  that equate to over $10 million in annual
sales.  The  packaging  capability  to support the DWDM product  growth is fully
operational.



                                       67
<PAGE>

Sales, Marketing and Customer Support

         The major  products of OCA, as well as the  Commercial  and  Government
Optics,  are all  supported by a direct  technical  sales force located at OCA's
California  and  Massachusetts   operations.  On  an  international  basis,  OCA
maintains representatives throughout Europe, Asia and South America.

Patents and Intellectual Property

      OCA believes the success of its business  depends more upon the  technical
competence and  creativity of its employees than on its patents,  trademarks and
copyrights.  Nevertheless,  OCA seeks patents,  when appropriate,  on inventions
concerning  new  products  and  improvements  as part of its  ongoing  research,
development  and  manufacturing  activities.  OCA also relies upon trade  secret
protection  for its  confidential  and  proprietary  information.  OCA routinely
enters into confidentiality agreements with other entities and individuals.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                   CONDITION AND RESULTS OF OPERATIONS OF OCA

Overview

         Current OCA management has been  responsible for operations since March
of 1990. In the past six years, the management team has devoted its attention to
the  transformation  of a diverse  operation,  with heavy emphasis on government
contracts,  into a unified business with significant  commercial  product lines.
The Company has materially improved its ability to withstand the fluctuations of
revenues and profits ordinarily expected from reliance on government contracts.

Nine Months ended March 31, 1996 and March 31, 1995

         Net Sales:  Net sales for the nine  months  ended  March 31,  1996 were
$21.5 million as compared to $19.7 million for the  corresponding  period a year
ago,  representing a 9% increase.  This increase was primarily  attributable  to
increased  sales of optical  filter  products  used in  biomedical  instruments,
expanded sales of commercial  optical  components  and  subsystems  used in high
precision  semiconductor machinery and analytical instruments and sales from our
new  product  line  of  fiber  optic  products  used  by the  telecommunications
industry. Sales of fiber optic products,  mainly wavelength division multiplexer
devices,  commenced  with a low volume of prototype  quantities  


                                       68
<PAGE>

during the nine  months  ended  March 31,  1996.  During this period the Company
began to ramp up for production of fiber optic products by adding  personnel and
equipment.

         During the nine months ended March 31, 1996 the combined  revenues from
government  optical  components and  subsystems  and government  electro-optical
sensors and cameras were  virtually  unchanged from the  corresponding  period a
year ago.

         Gross  Profit.  Gross  profit  as a  percentage  of net sales was 27.6%
during the nine months ended March 31, 1996,  a 3.0%  improvement  over 24.6% in
the corresponding  period in 1995. In 1996 the gross profit percentage  improved
as a result of increased  sales of optical  filter  products  incorporating  our
patented MicroPlasma(R) coating process which result in higher margins, and more
favorable pricing of government contracts for optical components and subsystems.

         Research and Development. Research and development expenditures for the
nine months ended March 31, 1996 increased by $832,000, or 248%, compared to the
corresponding  period a year ago. As a  percentage  of net sales,  research  and
development expenditures for the same periods were 5.4% in 1996 compared to 1.7%
in 1995.  The  increased  research and  development  expenditures  relate to our
ongoing development of fiber optic products for the telecommunications industry.

         Selling and Administrative. Selling and administrative expenses for the
nine months ended March 31, 1996  increased  by $240,000 or 7%,  compared to the
corresponding   period  a  year  ago.  As  a  percentage  of  net  sales,  these
expenditures  for the same periods were 17.4% in 1996 compared to 17.8% in 1995,
representing a slight decrease.

         Earnings from  Operations.  The increased  gross profit from additional
volume as well as improved product mix and pricing was almost entirely offset by
a  higher  level of  research  and  development.  Therefore,  earnings  remained
virtually unchanged,  at $1.0 million, for the nine month period ended March 31,
1996 versus the same period in 1995.

         Interest  Expense.  Interest  expense  increased during the nine months
ended March 31, 1996 by $76,000, or 13.8%,  compared to the corresponding period
a  year  ago.  The  increase  is  due  to a  higher  level  of  borrowings,  and
specifically  relate to $56,000 of interest  accrued on the obligation to redeem
common  stock  held by The  Perkin-Elmer  Corporation,  and  $20,000  for  other
borrowing.


                                       69

         Provision  For Income  Taxes.  The  Company  has a net  operating  loss
carryforward  for federal and state income tax purposes,  thus the effective tax
rate is not material. The income taxes for both periods shown are comparable.

         Net Income.  The Company had net income of $384,000 for the nine months
ended March 31, 1996  compard to $435,000  for the  corresponding  period a year
ago, a decrease of $51,000. This reduction in net income is principally a result
of increased research and development  expenditures and interest expense, offset
by higher gross profit arising from increased sales.

Twelve Months ended June 30, 1995 and June 30, 1994

         Net  Sales.  Net  sales for the year  ended  June 30,  1995 were  $26.5
million as compared to $25.2  million  for the prior year,  representing  a 5.4%
increase.  The  company  concentrated  its  efforts  on the  development  of the
commercial  segments of its business  with the result that  commercial  revenues
increased by $6.7 million in 1995. The increase is attributable to expanding our
customer base for commercial  optical  components  and  subsystems  used in high
precision  semiconductor  machinery and  analytical  instruments,  and increased
sales of  optical  filter  products  used in  biomedical  instruments.  Revenues
generated from government  contracts decreased to $10.8 million in 1995 compared
to $16.2 million in 1994.

         Gross  Profit.  Gross profit as a percentage  of net sales was 25.0% in
1995, a 1.4%  improvement  over 23.6% in 1994. This improvement is a result of a
more favorable  product mix caused by the Company's  increased  concentration on
commercial business.

         Research and Development. Research and development expenditures in 1995
increased by $469,000,  or 474%,  compared to 1994. As a percentage of revenues,
research  and  development  expenditures  in 1995 were 2.1%  compared to 0.4% in
1994. The increased research and development  expenditures relate to our ongoing
development of fiber optic products for the telecommunications industry.

         Selling and  Administrative.  Selling and  administrative  expenses for
1995 decreased $401,000,  or 7.8%, compared to 1994. As a percentage of revenues
these  expenditures  were 18.1% in 1995 compared to 20.7% in 1994.  The decrease
for 1995 was primarily  attributable a $430,000  charge related to a bad debt in
1994.  The  customer  filed  for  Chapter  11  protection  and was  subsequently
liquidated.



                                       70
<PAGE>

         Earnings  From  Operations.   Earnings  from  operations  doubled  from
$623,000  in 1994 to $1.2  million in 1995.  The  increased  gross  profit  from
additional  sales volume and a more favorable  product mix and lower selling and
administrative  expenses resulted in a significant  improvement despite a higher
level of research and development.

         Interest Expense. Interest expense remained virtually even from 1994 to
1995, and there was no increase in the level of borrowings.

         Provision  For Income  Taxes.  The  Company  had a net  operating  loss
carryforward  for federal and state income tax purposes,  thus the effective tax
rate is not material.

         Net Income.  The Company had a net income of $508,000 in 1995  compared
to a net loss of $147,000 in 1994.  The  improvement  was a result of  increased
sales coupled with improved margins in 1995.

Twelve Months ended June 30, 1994 and June 30, 1993

         Net  Sales.  Net  sales for the year  ended  June 30,  1994 were  $25.2
million as compared to $27.4  million  for the prior  year,  representing  an 8%
decrease.  The  decrease  is  directly  related  to a  softening  of  government
contracts for optical and  electro-optical  components and subsystems.  Revenues
generated from government  contracts decreased to $16.2 million in 1994 compared
to $20.6 million in 1993. With the ongoing shrinkage of the defense budget,  the
Company  concentrated on increasing the commercial  segments of its business and
exploring  opportunities  for new  proprietary  products.  The  results of these
efforts are expected to show a continuing  improvement  in product mix in future
years.

         Gross  Profit.  Gross profit as a percentage  of net sales was 23.6% in
19894,  a 4.1%  improvement  over  19.5% in  1993.  In 1994,  the  gross  profit
percentage  improved  as a result of a more  favorable  product  mix, as well as
improvements  in optical filter margins from  manufacturing  cost reductions and
improved productivity.

         Research and Development. Research and development expenditures in 1994
decreased by $392,000,  or 80%,  compared to 1993.  As a percentage of revenues,
research  and  development  expenditures  in 1994 were 0.4%  compared to 1.8% in
1993.  However, in 1994 and 1993, the Company received Small Business Innovative
Research  (SBIR) Program  Contracts.  These  contracts  provide the Company with
government  sponsored funds for research and development in specific areas.  The
revenue  related to the SBIR  contracts  has been  included in net sales and was
approximately  $1,453,000  in 



                                       71
<PAGE>

1994 and $355,000 in 1993.  Related expenses have been included in cost of goods
sold and were approximately $1,114,000 in 1994 and $254,000 in 1993.

         Selling and  Administrative.  Selling and  administrative  expenses for
1994  decreased  by $692,000,  or 12.0%  compared to 1993.  As a  percentage  of
revenues these  expenditures  were 20.7% in 1994 compared to 21.5% in 1993. This
decrease is  attributable  to the Company's  efforts to reduce costs in light of
lower anticipated revenues.

         Restructuring  Expenses.  In 1993,  the Company  restructured  its East
Coast operations by  consolidating  substantially  all of its Westward  facility
into its Marlborough  facility.  As a result of this restructuring,  the Company
incurred  costs of $833,000  related to a partial  termination  of the  facility
lease and a related  sublease,  the write-off of certain  assets and  associated
costs of the restructuring. Concurrently, the Company also restructured its work
force, resulting in $408,000 of severance costs.

         Earnings From Operations.  Earnings from operations improved in 1994 to
$623,000  compared  to a loss of $2.3  million  in 1993.  This is the  result of
improved  margins  and  reductions  in  expenses,  as well as the  non-recurring
restructuring charge only affecting 1993.

         Interest  Expense.  Interest  expense  increased  in  1994  by  $85,000
compared to 1993. The increase is due to a higher level of borrowings.

         Provision For Income  Taxes.  Due to the net loss in 1993 OCA has a net
operating  loss  carryforward  for  federal  and state tax  purposes.  In 1993 a
portion  of the tax loss was  carried  back to prior  years  resulting  in a tax
benefit in 1993.

         Net Income.  The Company  experienced a net loss of $147,000 in 1994 as
compared to a loss of $2.6 million in 1993.

Liquidity and Capital Resources


                                       72
<PAGE>

         Capital  Expenditures  during the years ended June 30,  1993,  1995 and
1995  were   approximately   $1.3  million,   $.06  million  and  $1.2  million,
respectively. These expenditures were principally for machinery and equipment to
upgrade  production  capabilities.  The Company's  capital  equipment  purchases
through  March 31, 1996 equaled $2.3  million and  included  approximately  $1.1
million for the fiber optics products.  The Company expects capital expenditures
in future  quarters to continue to be  significant  as  production  capacity for
fiber optics products is added to the Company's current manufacturing facility.

         At March 31,  1996,  the  Company  had a  positive  working  capital of
approximately  $2.0 million,  which excludes the amount owed to The Perkin-Elmer
Corporation for the repurchase of the shares of the Company's  redeemable common
stock. See Note 5 to the Company's  Financial  Statements  elsewhere herein. The
Company also had  approximately  $2.6 million of indebtedness for money borrowed
from its  bank at  March  31,  1996.  The  Company's  availability  for  further
borrowing,  based upon 80% of eligible  accounts  receivable,  was approximately
$600,000 at the same date.  The bank's  commitment to its line of credit expires
November 1, 1996,  and the Company  anticipates  no  difficulty in being able to
obtain a renewal thereof.

         In the  absence  of the  proposed  Merger  transaction,  the  Company's
present  capital  resources  would be inadequate  for its projected  needs.  The
Company  would need to raise  additional  equity  capital in order to be able to
satisfy its obligation to redeem the shares of common stock  presently  owned by
The Perkin-Elmer  Corporation and at the same time remain in compliance with the
terms of its  agreements  with its  lenders.  In  addition,  the  Company  has a
significant  amount of subordinated  indebtedness which will mature between July
1, 1997 and June 30, 1999. It is possible that the holders of this  subordinated
indebtedness might elect to use a portion of the principal of their notes to pay
the exercise price of the Common Stock  Purchase  Warrants which they also hold.
However,  based upon  discussions  with its  investment  advisors,  the  Company
believes  that its current  levels of  operations  and revenues will support its
ability to raise such equity and refinance such indebtedness.

Ownership of OCLI Common Stock

         After  giving  effect  to the  Merger,  assuming  the  purchase  of the
Perkin-Elmer  shares,  full  participation in the Merger by all OCA Shareholders
and the prior exercise of all  outstanding  options and warrants to purchase OCA
Common Stock, there will be approximately 11,430,548 shares of OCLI Common Stock
outstanding.  After giving effect to the Merger,  OCA Shareholders  would own in
the aggregate  approximately  14.9% of the issued and outstanding shares of OCLI
Common Stock.

         For  information   concerning  the  ownership  of  OCLI  Common  Stock,
including  OCLI Common Stock owned by directors and executive  officers of OCLI,
see  "AVAILABLE   INFORMATION"  and   "INCORPORATION  OF  CERTAIN  DOCUMENTS  BY
REFERENCE."

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


         OCLI and OCA have worked together on several projects over the past six
years. Beginning in 1990, OCLI subcontracted with OCA for the coating of missile
domes for the U.S Department of Defense. Under this arrangement,  OCA fabricated
the missile 



                                       76
<PAGE>

domes in its facilities in Garden Grove,  California and sent them to OCLI to be
coated at it  facilities  in Santa  Rosa.  Since  the  initial  order,  OCLI has
received several  follow-up orders from OCA for the coating of the missile domes
in addition to several other  smaller  coating  subcontracts  for which OCLI has
received orders worth approximately $657,000 since 1992.

         Beginning  in 1995,  OCA  subcontracted  with  OCLI for the  supply  of
optical subassemblies and optical fabrication. In fiscal 1995 OCLI placed orders
with OCA worth approximately  $75,000 and orders year-to-date in fiscal 1996 are
worth $407,000.

         In addition to being both  suppliers  and  customers to each other over
the last  several  years,  OCA and OCLI have both  competed  for optical  filter
business  in  the  defense,   aerospace,   medical  instrumentation  and  office
automation market segments along with other companies including, but not limited
to, Barr Associates,  Optical Filter Corporation, Varo, and Deposition Sciences,
Inc.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The  following  is a  summary  of  the  principal  federal  income  tax
consequences  of the Merger and is based upon the  applicable  provisions of the
Internal Revenue Code of 1986, As Amended (the "Code"),  regulations thereunder,
and published rulings and court decisions. Neither OCA nor OCLI intend to seek a
ruling from the Internal  Revenue Service with regard to the tax consequences of
the Merger.

         Under  present law, the Merger and the  conversion of each share of OCA
Common Stock into OCLI Common Stock should have the following  consequences  for
federal income tax purposes:

         1. The Merger  will  qualify as a  "reorganization"  as defined in Code
Sections 368(a)(1)(A) and 368(a)(2)(E).

         2. No gain or loss will be recognized by OCA as a result of the Merger.

         3. No gain or loss will be recognized by OCA  Shareholders who exchange
all of their OCA  Common  Stock  solely  for OCLI  Common  Stock in the  Merger.
Shareholders  who exercise  dissenters'  rights will recognize gain or loss upon
the receipt of cash for their shares measured by the difference between the cash
received  and the  basis of their  stock,  provided  they own no  shares of OCLI
Common Stock.



                                       77
<PAGE>

         4. The  aggregate  basis of the OCLI  Common  Stock  received by an OCA
Shareholder  will be the same as the aggregate basis of such  Shareholder in the
OCA Common Stock converted in the Merger.

         5. The  holding  period of the OCLI  Common  Stock  received  by an OCA
Shareholder  will include the period during which such  Shareholder held the OCA
Common  Stock  converted in the Merger,  provided  that such stock was held as a
capital asset on the Effective Date.

         6.  An OCA  Shareholder  who  receives  a cash  payment  in  lieu  of a
fractional  share of OCLI  Common  Stock will be  treated as if such  fractional
share  were  distributed  in the Merger and then  redeemed  by OCLI,  and should
recognize capital gain or loss measured by the difference  between the amount of
cash received and the Shareholder's basis in the fractional share (which will be
a pro rata portion of the Shareholder's  basis in the OCLI Common Stock received
in the Merger),  provided that such  Shareholder's OCA Common Stock is held as a
capital asset on the Effective Date.

         7. No gain or loss for federal  income tax purposes  will be recognized
by the holder of an option to purchase  shares of OCA Common  Stock  solely as a
result of the  conversion  of such options into options to purchase  OCLI Common
Stock.

         In order for the Merger to qualify  as a tax-free  reorganization,  the
OCA  Shareholders  must have the  requisite  "continuity  of  interest"  through
ownership of the OCLI Common  Stock.  It is the ruling  position of the Internal
Revenue  Service that the  "continuity of interest"  requirement is satisfied if
there  is a  continuing  interest  through  stock  ownership  in  the  acquiring
corporation on the part of the former shareholders of the acquired  corporation,
without  any  plan or  intention  by the  former  shareholders  of the  acquired
corporation  to sell,  exchange or otherwise  dispose of stock of the  acquiring
corporation,  that  is  equal  in  value,  as  of  the  effective  date  of  the
reorganization,  to at least  50% of the value of all the  formerly  outstanding
stock of the acquired corporation as of the same date. There can be no assurance
that the former  Shareholders  of OCA will not,  pursuant  to a present  plan or
intention,  sell or  otherwise  dispose of the OCLI Common Stock in a sufficient
amount to violate this requirement.  However,  the holders of a majority of such
shares have represented that they have no such present plan or intention.

         Holders  of OCA  Common  Stock  are  urged to  consult  with  their tax
advisers as to the effect  under state,  local and foreign  income and other tax
laws of the Merger.

         The  consolidated   financial  statements  and  the  related  financial
statement schedule incorporated in this Registration Statement by reference from
Optical Coating Laboratory, Inc.'s Annual Report on Form 10-K for the year ended
October  31,  1995 have been  audited  by  Deloitte  & Touche  LLP,  independent
auditors as stated in their report,  which is incorporated  herein by reference,
and have been so  incorporated in reliance on the report of such firm given upon
their authority as experts in accounting and auditing.

         With respect to the unaudited interim financial  information of Optical
Coating Laboratory,  Inc. for the periods ended January 28, 1996 and January 31,
1995 and April 28,  1996 and April 30,  1995,  which is  incorporated  herein by
reference,  Deloitte & Touche LLP have applied limited  procedures in accordance
with professional standards for a review of such information. However, as stated
in their reports  included in the Optical Coating  Laboratory,  Inc.'s Quarterly
Reports on Form 10-Q for the  quarters  ended  January  28, 1996 and January 31,
1995 and April 28, 1996 and April 30, 1995 and incorporated by reference herein,
they did not audit and they do not express an opinion on that interim  financial
information.  Accordingly,  the  degree of  reliance  on their  reports  on such
information  should be restricted  in light of the limited  nature of the review
procedures  applied.  Deloitte  & Touche LLP are not  subject  to the  liability
provisions of Section 11 of the  Securities Act of 1933 for their reports on the
unaudited interim financial  information because those reports are not "reports"
or a "part" of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Act.

         The consolidated financial statements of Optical Corporation of America
as of June 30, 1995 and 1994 and for each of the three years in the period ended
June 30, 1995  included  and  incorporated  by  reference  in this  Registration
Statement have been audited by Deloitte & Touche LLP, independent  auditors,  as
stated in their  report,  which  are  included  and  incorporated  by  reference
therein,  and have been so included and incorporated in reliance upon the report
of such firm given upon their authority as experts in accounting and auditing.

         The  validity  of the OCLI  Common  Stock to be issued  pursuant to the
Merger will be passed upon for OCLI by Collette & Erickson LLP, counsel to OCLI.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

         Section 145 of the General Corporation Law of the State of Delaware, as
amended,  gives  Delaware  corporations  the  power to  indemnify  each of their
present and former  directors or officers under certain  circumstances,  if such
person acted in good faith and in a manner which he reasonably believed to be in
or not opposed to the best interests of the corporation.

         Article Fourteen of the Registrant's  Amended and Restated  Certificate
of  Incorporation  and  OCLI's  By-Laws  provide  that OCLI will  indemnify  its
directors  and officers to the fullest  extent  permitted  under  Delaware  law,
including circumstances in which indemnification is otherwise discretionary. The
Company submitted these charter and By-Law  provisions to its stockholders,  who
approved  them in March  1987.  In  addition,  OCLI has  entered  into  separate
Indemnification  Agreements  with its  directors and officers to the full extent
permitted by applicable law and OCLI's Certificate of Incorporation. The general
effect of the indemnification  provisions of the By-Laws and the Indemnification
Agreements  is to require OCLI,  among other things,  to indemnify its directors
and  officers  against  certain  liabilities  that may  arise by reason of their
status or service as  directors  or officers  (provided  the officer or director
acted in good faith and in a manner he or she  believed  to be in or not opposed
to the best  interests  of OCLI and,  with  respect  to a  criminal  proceeding,
provided  he or she had no  reasonable  cause to believe  that the  conduct  was
unlawful), and to advance their expenses (including attorneys' fees) incurred as
a result of any proceeding  against them as to which they could be  indemnified.
The Company  believes  that its charter and By-law  provisions  and the separate
Indemnification Agreements are necessary to attract and retain qualified persons
as directors and officers.

         At  present,  OCLI  is  not  aware  of  any  threatened  litigation  or
proceeding which could result in a claim for  indemnification by any director or
officer.

         Section 145 of the Delaware  General  Corporation  Law provides for the
indemnification  of  officers,  directors  and other  corporate  agents in terms
sufficiently broad to indemnify such persons, under certain  circumstances,  for
liabilities  (including  reimbursement of expenses  incurred)  arising under the
Securities Act of 1933.



                                       82
<PAGE>

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers or persons controlling OCLI
pursuant to the foregoing provisions, OCLI has been informed that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is therefore unenforceable.

         The Registrant  maintains  officers' and directors'  insurance covering
certain  liabilities  that may be  incurred  by officers  and  directors  in the
performance of their duties.

Item 21.  Exhibits and Financial Statement Schedules.

         See the Exhibit Index  included  immediately  preceding the exhibits to
this Registration Statement.

Item 22.  Undertakings.

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement;

                  (i) To include any prospectus  required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the  prospectus any facts or events arising
after the  effective  date of the  registration  statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement;

                  (iii) To include any material  information with respect to the
plan of distribution not previously  disclosed in the registration  statement or
any material change to such information in the registration statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.


                                       83
<PAGE>

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  that is  incorporated  by  reference  in this
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned  Registrant hereby undertakes as follows: that prior to
any public  reoffering of the securities  registered  hereunder through use of a
prospectus  which is a part of this  registration  statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed to be  underwriters,  in  addition to the  information
called for by the other Items of the applicable form.

         The  Registrant  undertakes  that  every  prospectus  (i) that is filed
pursuant to the immediately  preceding undertaking or (ii) that purports to meet
the  requirements of section  10(a)(3) of the Act and is used in connection with
an offering  of  securities  subject to Rule 415,  will be filed as a part of an
amendment  to the  registration  statement  and  will  not be  used  until  such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act of 1933,  each such  post-effective  amendment shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether 



                                       84
<PAGE>

such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Items 4, 10(b),  11, or 13 of this Form,  within one  business day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         The undersigned  Registrant  hereby  undertakes to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

                         Mass. Ann. Laws ch. 156B (1996)

S 85. Rights of Minority Stockholder, etc.

   A stockholder in any corporation  organized  under the laws of  Massachusetts
which shall have duly voted to consolidate or merge with another  corporation or
corporations under the provisions of sections  seventy-eight or seventy-nine who
objects to such  consolidation  or merger may demand  payment for his stock from
the resulting or surviving  corporation  and an appraisal in accordance with the
provisions  of  sections  eighty-six  to  ninety-eight,   inclusive,   and  such
stockholder and the resulting or surviving corporation shall have the rights and
duties and follow the procedure set forth in those sections.  This section shall
not apply to the  holders  of any shares of stock of a  constituent  corporation
surviving a merger if, as permitted by subsection (c) of section  seventy-eight,
the merger did not require for its  approval a vote of the  stockholders  of the
surviving corporation.

HISTORY: 1964, 723, S 1; 1969, 392, S 22.

S 86.  Applicability  of S 87 to 98;  Prerequisites  of Objecting  Stockholder's
Right to Demand Payment for Shares and Appraisal Thereof.

   If a corporation  proposes to take a corporate action as to which any section
of this chapter  provides  that a  stockholder  who objects to such action shall
have the  right to demand  payment  for his  shares  and an  appraisal  thereof,
sections  eighty-seven  to  ninety-eight,   inclusive,  shall  apply  except  as
otherwise  specifically  provided  in any  section  of this  chapter.  Except as
provided in sections  eighty-two and  eighty-three,  three, no stockholder shall
have such right  unless (1) he files with the  corporation  before the taking of
the vote of the shareholders on such corporate action,  written objection to the
proposed  action stating that he intends to demand payment for his shares if the
action  is taken  and (2) his  shares  are not  voted  in favor of the  proposed
action.

S 87. Notice of Certain Stockholders' Meetings to Contain Statement of Rights of
Objecting Stockholders; Effect of Giving Notice; Form.

   The  notice of the  meeting of  stockholders  at which the  approval  of such
proposed  action is to be considered  shall contain a statement of the rights of
objecting stockholders.  The giving of such notice shall not be deemed to create
any  rights in any  stockholder  receiving  the same to demand  payment  for his
stock,  and the  directors  may  authorize the inclusion in any such notice of a
statement of opinion by the management as to the existence or  non-existence  of
the right of the  stockholders  to demand  payment for their stock on account of
the proposed  corporate action.  The notice may be in such form as the directors
or officers calling the meeting deem advisable, but the following form of notice
shall be sufficient to comply with this section:

   "If the action  proposed is approved by the  stockholders  at the meeting and
effected by the corporation,  any stockholder (1) who files with the corporation
before the taking of the vote on the approval of such action,  written objection
to the proposed  action stating that he intends to demand payment for his shares
if the  action  is taken  and (2)  whose  shares  are not voted in favor of such
action has or may have the right to demand in writing from the corporation  (or,
in the case of a consolidation or merger, the name of the resulting or surviving
corporation shall be inserted),  within twenty days after the date of mailing to
him of notice in writing that the corporate action has become effective, payment
for his shares and an appraisal of the value thereof.  Such  corporation and any
such stockholder shall in such cases have the rights and duties and shall follow
the procedure set forth in sections 88 to 98, inclusive,  of chapter 156B of the
General Laws of Massachusetts."

HISTORY: 1964, 723, S 1; 1973, 749, S 2.

S 88. Corporation Taking Action, etc., to Notify Certain Objecting  Stockholders
that Certain Approved Action Has Become Effective, etc.

   The  corporation  taking  such  action,  or  in  the  case  of  a  merger  or
consolidation  the surviving or resulting  corporation,  shall,  within ten days
after the date on which such  corporate  action  became  effective,  notify each
stockholder who filed a written  objection  meeting the  requirements of section
eighty-six  and whose  shares  were not voted in favor of the  approval  of such
action,  that the 

                                       2
<PAGE>

action  approved at the meeting of the  corporation of which he is a stockholder
has become  effective.  The giving of such notice  shall not be deemed to create
any  rights in any  stockholder  receiving  the same to demand  payment  for his
stock.  The notice shall be sent by registered or certified  mail,  addressed to
the  stockholder  at his last known  address as it appears in the records of the
corporation.

HISTORY: 1964, 723, S 1; 1973, 749, S 3.


S 89.  Corporation to Pay to Certain Objecting  Stockholders Fair Value of Their
Shares on Demand, etc.

   If within twenty days after the date of mailing of a notice under  subsection
(e) or section eighty-two,  subsection (f) of section  eighty-three,  or section
eighty-eight,  any stockholder to whom the corporation was required to give such
notice shall demand in writing from the  corporation  taking such action,  or in
the  case  of  a  consolidation  or  merger  from  the  resulting  or  surviving
corporation,  payment for his stock,  the corporation  upon which such demand is
made shall pay to him the fair value of his stock  within  thirty days after the
expiration of the period during which such demand may be made.

HISTORY: 1964, 723, S 1; 1973, 749, S 4.

S 90. Bill in Equity to Determine  Value of Stock of Objecting  Stockholders  on
Failure to Agree on Value Thereof, etc.

   If during the period of thirty days provided for in section  eighty-nine  the
corporation  upon which such demand is made and any such  objecting  stockholder
fail to  agree as to the  value  of such  stock,  such  corporation  or any such
stockholder  may within  four months  after the  expiration  of such  thirty-day
period demand a  determination  of the value of the stock of all such  objecting
stockholders by a bill in equity filed in the superior court in the county where
the  corporation in which such objecting  stockholder  held stock had or has its
principal office in the commonwealth.

HISTORY: 1964, 723, S 1.

S 91. Bill in Equity to Determine  Value of Stock of Objecting  Stockholders  on

on Corporation; Notice to Stockholder Parties, etc.

<PAGE>

   If the bill is filed by the corporation,  it shall name as parties respondent
all  stockholders  who have demanded  payment for their shares and with whom the
corporation  has not reached  agreement as to the value thereof.  If the bill is
filed by a stockholder,  he shall bring the bill in his own behalf and in behalf
of all other  stockholders  who have demanded  payment for their shares and with
whom the  corporation  has not  reached  agreement  as to the value  thereof and
service of the bill shall be made upon the  corporation  by subpoena with a copy
of the bill annexed.  The corporation shall file with its answer a duly verified
list of all such other  stockholders,  and such stockholders  shall thereupon be
deemed to have been  added as parties to the bill.  The  corporation  shall give
notice in such form and returnable on such date as the court shall order to each
stockholder party to the bill by registered or certified mail,  addressed to the
last  known  address  of  such  stockholder  as  shown  in  the  records  of the
corporation,  and the court may order such  additional  notice by publication or
otherwise as it deems  advisable.  Each stockholder who makes demand as provided
in section  eighty-nine  shall be deemed to have  consented to the provisions of
this section relating to notice,  and the giving of notice by the corporation to
any such  stockholder  in  compliance  with the  order of the  court  shall be a
sufficient  service of process on him. Failure to give notice to any stockholder
making demand shall not invalidate the  proceedings as to other  stockholders to
whom notice was properly  given,  and the court may at any time before the entry
of a final decree make supplementary orders of notice.

HISTORY: 1964, 723, S 1.

S 92. Bill in Equity to Determine  Value of Stock of Objecting  Stockholders  on
Failure to Agree on Value Thereof,  etc.; Entry of Decree  Determining  Value of
Stock; Date on Which Value is to Be Determined.

   After  hearing the court shall enter a decree  determining  the fair value of
the stock of those stockholders who have become entitled to the valuation of and
payment for their  shares,  and shall order the  corporation  to make payment of
such value,  together with  interest,  if any, as hereinafter  provided,  to the
stockholders  entitled  thereto upon the transfer by them to the  corporation of
the certificates  representing such stock if certificated or, if uncertificated,
upon receipt of an instruction  transferring such stock to the corporation.  For
this  purpose,  the  value  of the  shares  shall  be  determined  as of the day
preceding the date of the vote approving the proposed corporate action 

                                       4

and shall be exclusive of any element of value arising from the  expectation  or
accomplishment of the proposed corporate action.

HISTORY: 1964, 723, S 1.
      Amended by 1983, 522, S 22, approved November 29, 1983; by S 24, effective

Failure to Agree on Value Thereof,  etc.; Court May Refer Bill, etc., to Special
Master to Hear Parties, etc.

   The  court in its  discretion  may  refer  the bill or any  question  arising
thereunder to a special master to hear the parties, make findings and report the
same to the court,  all in accordance with the usual practice in suits in equity
in the superior court.

HISTORY: 1964, 723, S 1.

   S 94. Bill in Equity to Determine  Value of Stock of  Objecting  Stockholders
Upon  Failure  to  Agree  Thereon;   Notation  of  Pendancy  of  Bill  on  Stock
Certificates;  Notation  of Pendancy of Bill in  Corporate  Records  Relative to
Uncertified Shares.

   On motion the court may order stockholder parties to the bill to submit their
certificates  of  stock  to the  corporation  for the  notation  thereon  of the
pendancy of the bill and may order the  corporation to note such pendancy in its
records  with  respect to any  uncertificated  shares  held by such  stockholder
parties,  and may on motion dismiss the bill as to any  stockholder who fails to
comply with such order.

HISTORY: 1964, 723, S 1.
      Amended by 1983, 522, S 23, approved November 29, 1983; by S 24, effective

Award, etc.

   The costs of the bill, including the reasonable  compensation and expenses of
any  master  appointed  by the  court,  but  exclusive  of fees of counsel or of
experts  retained by any party,  shall be determined by the court and taxed upon
the  parties  to the  bill,  or any of them,  in such  

                                       5

manner as appears to be  equitable,  except  that all costs of giving  notice to
stockholders  as  provided  in this  chapter  shall be paid by the  corporation.
Interest  shall be paid upon any award from the date of the vote  approving  the
proposed  corporate  action,  and the court may on application of any interested
party  determine  the  amount  of  interest  to be  paid  in  the  case  of  any
stockholder.

HISTORY: 1964, 723, S 1; 1965, 685, S 41.

S 96.  Stockholder  Demanding  Payment  for  Stock  Not  Entitled  to  Notice of
Stockholders'  Meetings  or  to  Vote  Stock  or  to  Receive  Dividends,  etc.;
Exceptions.

   Any  stockholder  who has demanded  payment for his stock as provided in this
chapter  shall  not   thereafter  be  entitled  to  notice  of  any  meeting  of
stockholders  or to vote such stock for any purpose and shall not be entitled to
the payment of dividends or other distribution on the stock (except dividends or
other  distributions  payable to stockholders of record at a date which is prior
to the date of the vote approving the proposed  corporate action) unless:

   (1) A bill shall not be filed within the time provided in section ninety;

   (2) A bill, if filed, shall be dismissed as to such stockholder; or

   (3) Such stockholder  shall with the written approval of the corporation,  or

                          AGREEMENT AND PLAN OF MERGER

     THIS  AGREEMENT  is  executed  as of June 28,  1996,  by and among  Optical
Coating  Laboratory,  Inc.,  a  Delaware  corporation,  having an office at 2789
Northpoint  Parkway,  Santa Rosa,  California  95407  ("OCLI"),  OCA Acquisition
Corp., a Delaware  corporation  and a wholly-owned  subsidiary of OCLI having an
address in OCLI's care  ("Acquisition"),  and Optical  Corporation of America, a
Massachusetts  corporation  having an office  at 170 Locke  Drive,  Marlborough,
Massachusetts  01752 and its  Headquarters  address at 7421  Orangewood  Avenue,
Garden Grove, California 92641 ("OCA").

      WHEREAS,  the Boards of  Directors of  Acquisition  and OCA deem it in the
best  interest  of such  corporations  and their  respective  shareholders  that
Acquisition be merged into and with OCA on the terms and conditions set forth in
this Agreement,  as a result of which OCA will become a wholly-owned  subsidiary
of OCLI; and

      WHEREAS, the Board of Directors of OCLI has approved the merger;

      NOW  THEREFORE,  for and in  consideration  of the  mutual  covenants  and
agreements hereinafter set forth, and other good and valuable consideration, the
receipt of which is acknowledged by each party hereto,  the parties hereto agree
as follows:

                                    ARTICLE 1

                                   THE MERGER

     1.1.  Agreement and Plan of Merger.  Effective as of the Effective Date (as
defined in Section  2.2  below),  Acquisition  shall be merged with and into OCA
(hereinafter sometimes called the "Merger") in accordance with the terms of this
Agreement.  OCA shall be the  corporation  surviving the Merger (the  "Surviving
Corporation"),  and the separate  existence of Acquisition shall cease as of the
Merger.  The Articles of Organization  and Bylaws of OCA, in effect  immediately
prior to the effective  time of the Merger,  shall  thereafter  continue in full
force and effect as the  Articles of  Organization  and Bylaws of the  Surviving
Corporation.  The directors and officers of the Surviving Corporation,  from and
after the Effective  Date,  shall be the  directors  and officers  listed in the
Articles of Merger as defined in Section 2.2,  each to hold office in accordance
with  applicable  law and the  Articles of  Organization  and Bylaws


<PAGE>

of OCA. The effect of the Merger shall be as provided by  applicable  provisions
of the Delaware General Corporation Law ("DGCL") and the Massachusetts  Business
Corporation Law ("MBCL").

     1.2.  Conversion of OCA's Shares. At the effective time of the Merger, each
share of OCA's common stock,  $.01 par value ("OCA Common  Stock"),  outstanding
immediately  prior thereto (herein referred to as a "OCA Share" and collectively
as the "OCA  Shares")  shall,  by virtue of the Merger and without any action on
the part of the holder thereof, but subject to this Section and to Sections 1.4,
1.5, 1.6 and 1.7 below,  be canceled and converted into the right to receive two
and 42/1000  (2.042) shares (the "OCLI Shares") of OCLI common stock,  $0.01 par
value (the "OCLI  Common  Stock").  The whole and fraction of an OCLI Share into
which  each  OCA  Share  is  to be  converted  pursuant  to  this  Agreement  is
hereinafter referred to as the "Exchange Ratio."

     1.3. OCA Stock  Options and Warrants.  At or prior to the  Effective  Date,
OCLI and OCA shall take all action  necessary to cause the assumption by OCLI as
of the  Effective  Date of the options and warrants to purchase OCA Common Stock
which are  listed in the  Disclosure  Schedule  described  in  Section  3.2 (the
"Disclosure  Schedule"),   outstanding  as  of  the  Effective  Date  (the  "OCA
Options").  Each of the OCA Options shall be converted without any action on the
part of the holder thereof (but subject to any amendments  thereto or waivers of
the terms and provisions  thereof as may be required to permit such  conversion,
as may be  specified  in the  Disclosure  Schedule)  into an option to  purchase
shares of OCLI Common Stock (the "OCLI  Options") as of the Effective  Date. The
number of shares of OCLI Common  Stock that each  record  holder of an option or
warrant  agreement which represents OCA Options (the  "Optionholders")  shall be
entitled to receive  upon the  exercise of such OCA Option  shall be a number of
whole and fractional  shares  determined by multiplying  the number of shares of
OCA Common Stock subject to such OCA Option, determined at the close of business
on the business day  immediately  preceding the Effective  Date, by the Exchange
Ratio.  The option  exercise price of each share of OCLI Common Stock subject to
an assumed OCA Option shall be the amount (rounded up to the nearest whole cent)
obtained by dividing the  exercise  price per share of OCA Common Stock at which
such OCA Option is  exercisable  immediately  before the  Effective  Date by the
Exchange Ratio. Except as described in the Disclosure  Schedule,  the assumption
and conversion of OCA Options to OCLI Options as provided  herein shall not give
the 

                                       2
<PAGE>

Optionholders  additional  benefits which they did not have immediately prior to
the Effective Date,  result in any  acceleration of any vesting schedule for any
OCA Option,  or relieve the  Optionholders  of any  obligations or  restrictions
applicable  to their OCA Options or the shares  obtainable  upon exercise of the
OCA  Options.  Only  whole  shares of OCLI  Common  Stock  shall be issued  upon
exercise of any OCLI Option and in lieu of  receiving  any  fractional  share of
OCLI  Common  Stock,  the holder of such option  shall  receive in cash the fair
market value of the fractional  share,  net of the applicable  exercise price of
the fractional share and applicable withholding taxes, if any.

     1.4.  Limit on Issuance of OCLI  Shares.  Anything to the  contrary  herein
notwithstanding,  the total  number of OCLI Shares which shall be required to be
issued  pursuant  to Section 1.2 and upon the  exercise of OCA Options  that are
converted into OCLI Options  pursuant to Section 1.3  (calculated as if all such
OCLI  Options are  exercised  on the  Effective  Date) shall not (except as such
number of shares  shall be  required to be  adjusted  pursuant to Section  1.10)
exceed  1,930,869.  In the event that the  application of the Exchange Ratio set
forth in Section 1.2 could result in the issuance of more than 1,930,869 Shares,
such  Exchange  Ratio rate shall be  automatically  adjusted such that the total
number of OCLI Shares will not exceed 1,930,869.

     1.5.  Dissenting  Shares.  Each  outstanding  OCA  Share  held  by  an  OCA
shareholder  who has demanded and  perfected his or her right to an appraisal of
his or her OCA Shares in accordance  with Sections 85-98 of the MBCL and who has
not  effectively   withdrawn  or  lost  his  or  her  right  to  such  appraisal
("Dissenting  Shares")  shall not be converted  into or  represent  the right to
receive the OCLI Shares  represented by such OCA Shares  pursuant to Section 1.2
above,  but the holder  thereof  shall be  entitled  only to such  rights as are
granted by Sections 85-98 of the MBCL.

     1.6. Payment for the OCA Shares.  Promptly  following the Effective Date of
the Merger, First Interstate Bank of California (or its  successor-in-interest),
OCLI's stock  transfer  agent (the  "Exchange  Agent"),  shall  transmit to each
record holder of an outstanding  certificate which prior thereto represented OCA
Shares (the "Shareholders") a form of letter of transmittal and instructions for
use in effecting  the  surrender of such  certificate  and/or  option or warrant
agreement  in  exchange  for the OCLI Shares  represented  by such OCA Shares or
exercised  OCA  Option.  Upon  the  surrender  to the  Exchange  Agent  of  such
certificates  and a duly  executed  letter of  transmittal  and 

                                       3
<PAGE>

any required tax  certifications,  in  accordance  with such  instructions,  the
Exchange Agent shall deliver a certificate  for the OCLI Shares that such person
is entitled to receive,  minus the  deduction  specified in Section 1.7 and cash
(if any) to which such holder is entitled pursuant to Sections 1.2, 1.9 and 1.10
of this Agreement. It shall be a condition of such payment and delivery that the
surrendered  certificate  be properly  endorsed or  otherwise in proper form for
transfer  and that the person  requesting  such shall pay any  transfer or other
taxes  required  by reason of such  payment  or  delivery  or  establish  to the
satisfaction of the Exchange Agent,  OCLI and/or the Surviving  Corporation that
such tax has been paid or is not applicable.  Until so surrendered for exchange,
each certificate heretofore representing OCA Common Stock (other than Dissenting
Shares)  shall,  subject to Section  1.7 hereof,  be deemed for all  purposes to
evidence the right to receive the  consideration as described in accordance with
Section 1.2 above; provided, however, that unless and until any such outstanding
certificate is so surrendered,  the holder of such outstanding certificate shall
cease to have any rights as a stockholder of OCA, except such rights, if any, as
such holder may have with respect to Dissenting Shares and shall not be entitled
to receive any  consideration  from the Surviving  Corporation  and/or OCLI with
respect to the OCA Shares represented by such certificate.  Unless and until any
such  outstanding  certificates  for OCA  Shares  shall  be so  surrendered,  no
dividend  (cash or stock)  payable to holders of record of shares of OCLI Common
Stock as of any  date  subsequent  to the  Effective  Date  shall be paid to the
holder of any such outstanding certificate and his other rights as a stockholder
of OCLI  shall  be  suspended,  but  upon  such  surrender  of such  outstanding
certificate  there  shall be paid to the  record  holder of the  certificate  of
shares of OCLI Common Stock issued in exchange therefor the amount of dividends,
if any, without interest and less any taxes which may have been imposed thereon,
that have theretofore  become payable with respect to the number of those shares
of OCLI Common Stock represented by such certificate  issued upon such surrender
and exchange,  and his other rights as a stockholder of OCLI shall thereafter be
restored.

     1.7.  Escrow  Account.   For  the  purpose  of  providing  support  of  the
representations and warranties contained herein and to induce OCLI to enter into
this Agreement,  ten percent (10%) of OCLI Shares each Shareholder has the right
to beneficially  receive  pursuant to Section 1.2 shall be withheld from payment
to such  Shareholder  pursuant  to Section  1.2 and shall be set aside in escrow
pursuant to the terms of an  Indemnification  and Stock  Escrow  Agreement to be

                                       4
<PAGE>

entered  into  at  the  Closing  by  and  among  OCLI,   OCA,  the   Shareholder
Representative  (as defined therein) and First Interstate Bank, as escrow agent,
in the form of Exhibit A attached  hereto and  incorporated  herein by reference
(the "Escrow Agreement"). The amount of shares placed in escrow pursuant to this
Section 1.7 shall be considered the "Escrowed Shares." The Escrowed Shares shall
be held as a trust  fund and  shall  not be  subject  to any  lien,  attachment,
trustee process or any other judicial  process of any creditor of any party, and
shall be held and  disbursed  by the Escrow Agent solely for the purposes and in
accordance  with the terms of the  Escrow  Agreement.  It is  intended  that the
assets  held in  escrow  as  above  provided  shall  facilitate  OCLI's  and the
Surviving  Corporation's  ability to recover  amounts to which they are entitled
under this  Agreement or the Escrow  Agreement and to satisfy claims of OCLI and
Acquisition  arising  as a result of this  Agreement  or the  Escrow  Agreement.
Accordingly,  and to the extent necessary to provide such protection to OCLI and
the Surviving Corporation, property held in escrow thereunder shall be available
to satisfy claims of OCLI and the Surviving  Corporation under this Agreement or
the Escrow Agreement to the extent provided in such agreements.  The adoption of
this  Agreement  and  the  approval  of the  Merger  by the  Shareholders  shall
constitute  approval  of the Escrow  Agreement,  including  without  limitation,
placement  and  escrow  of  the  Escrowed  Shares  and  the  appointment  of the
Shareholder Representative.

     1.8. Certain Other Agreements. Concurrently with the execution and delivery
of this  Agreement,  OCA shall  cause each  individual  identified  in Exhibit B
("Affiliate") to deliver to OCLI an Affiliate Agreement in the form of Exhibit C
attached hereto and a Continuity of Interest Certificate in the form attached as
Exhibit  D  hereto,   each  duly  executed  and  delivered  by  such  Affiliates
(collectively, the "Affiliate Agreements").

     1.9. No Fractional Shares of OCLI Common Stock.  Notwithstanding  any other
provision  of this  Agreement,  neither  certificates  nor scrip for  fractional
shares of OCLI Common Stock shall be issued to any holder of OCA Common Stock in
the Merger and the holder  thereof  shall not be entitled to any voting or other
rights  of a  holder  of  shares  or  a  fractional  share  interest.  Each  OCA
Shareholder  who  otherwise  would have been entitled to receive a fraction of a
share of OCLI Common Stock shall receive in lieu thereof cash, without interest,
in an amount determined by multiplying such Shareholder's fractional interest by
the closing price of OCLI Common Stock as reported on the Nasdaq

                                       5

<PAGE>

National  Market System on the Effective Date. All amounts of cash in respect of
fractional  interests which have not been claimed at the end of three years from
the Effective Date by surrender of  certificates  for shares of OCA Common Stock
shall be delivered by the Exchange Agent to the Surviving  Corporation,  subject
to the provisions of applicable  escheat or similar laws, for the account of the
holders entitled thereto.

     1.10.  Adjustments.  In the event OCLI shall  declare,  pay, make or effect
between the date of this Agreement and the Effective Date (a) any stock dividend
or other  distribution  in respect of the OCLI Common Stock payable in shares of
capital stock of OCLI,  (b) any stock split or other  subdivision of outstanding
shares of OCLI Common Stock into a larger number of shares,  (c) any combination
of outstanding  shares of OCLI Common Stock into a smaller number of shares, (d)
any  reclassification of OCLI Common Stock into other shares of capital stock or
securities,  or (e) any exchange of the outstanding shares of OCLI Common Stock,
in connection with a merger or  consolidation  of OCLI or sale by OCLI of all or
part of its  assets,  for a  different  number  or class of  shares  of stock or
securities of OCLI or for the shares of the capital stock or other securities of
any other  corporation,  appropriate  adjustment  shall be made in the  Exchange
Ratio as may be required to put the  Shareholders in the same position as if the
record date, with respect to any such transaction or transactions which shall so
occur, had been immediately  after the Effective Date, or otherwise to carry out
the intents and purposes of this Agreement.

     1.11.  Closing of Stock  Transfer  Books.  The stock  transfer books of OCA
shall be  closed  at the  close of  business  on the  business  day  immediately
preceding  the  Effective  Date.  In the event of a transfer of ownership of OCA
Common Stock,  the shares of OCLI Common Stock and cash (if any) to be issued in
the  Merger  as  provided  herein  may  be  delivered  to a  transferee,  if the
certificate  representing  such OCA Common  Stock is  presented  to the Exchange
Agent,  accompanied  by all  documents  required  to  evidence  and effect  such
transfer and by payment of any applicable stock transfer taxes.

     1.12.  Lost  Certificates.  In the event  any  certificate  representing  a
Shareholder's OCA Shares or any instrument representing the right to acquire OCA
Shares  shall  have  been  lost,  stolen  or  destroyed,  upon the  making of an
affidavit  of that fact by the person  claiming  such  certificate  or option or
warrant  instrument to be lost,  stolen or 

                                       6

<PAGE>

destroyed,  the  Exchange  Agent or the  Surviving  Corporation  shall  issue in
exchange  for such lost,  stolen or destroyed  certificate  or option or warrant
instrument the  consideration  or instrument  payable or deliverable in exchange
therefor  pursuant to this Article I. The Board of  Directors  of the  Surviving
Corporation  or the  Exchange  Agent may, in its  discretion  and as a condition
precedent to the  issuance  thereof,  require the owner of such lost,  stolen or
destroyed certificate or option or warrant instrument to give the Exchange Agent
or the  Surviving  Corporation  a bond in such sum as it may direct as indemnity
against  any claim  that may be made  against  the  Surviving  Corporation  with
respect to the certificate or option or warrant  instrument alleged to have been
lost, stolen or destroyed.

     1.13.  Conversion of Acquisition  Shares. At the Effective Date, each share
of Acquisition's  common stock  outstanding  immediately prior thereto shall, by
virtue of the Merger and without  any action on the part of the holder  thereof,
be canceled and converted into one (1) fully paid and nonassessable common share
of the  Surviving  Corporation,  which shares shall be registered in the name of
and beneficially owned by OCLI.

     1.14.  Adoption.  This Agreement shall be submitted to the  shareholders of
Acquisition and OCA as provided by law. In the case of Acquisition, OCLI, as its
sole  shareholder,  shall  vote all its  shares  in favor  of  adoption  of this
Agreement.  In the  case  of OCA,  this  Agreement  shall  be  submitted  to its
shareholders  at a duly called and held  shareholder  meeting for their approval
pursuant to the MBCL.

                                   ARTICLE II

of Merger or the Certificate of Merger).  The term  "Effective  Date" shall mean

corporation and in good standing.

          (b)  Capitalization.  The authorized  capital stock of OCA consists of
2,000,000  shares of OCA Common  Stock.  There is no other  capital stock of OCA
authorized for issuance. As of date of this Agreement, there were 783,577 shares
of OCA's Common Stock issued and  outstanding,  and these shares  constitute the
total issued and outstanding share capital of OCA. The Disclosure  Schedule sets
forth a complete and accurate list of all Shareholders, indicating the number of
OCA Shares held by such Shareholder and such  Shareholder's  residence  address.
All of such shares have been duly authorized and validly issued, are fully paid,
nonassessable  and  free  of  preemptive  rights.  The  offer  and  sale  of all
outstanding  securities  of OCA  complied  with  applicable  federal,  state and
foreign securities laws.

     As of the date of this  Agreement,  OCA had  authorized  and  reserved  for
issuance  162,000 shares of OCA Common Stock upon the exercise of OCA Options in
the amounts listed on the Disclosure Schedule,  which list indicates the address
of each OCA  Optionholder.  All other options or warrants to purchase OCA Common
Stock  have  expired  or  have  been  legally  terminated.  There  are no  other
outstanding  options or warrants to purchase  shares of OCA Common Stock.  Since
June 30,  1995,  no shares of capital  stock of OCA have been  repurchased  from
shareholders. No shares of OCA's capital stock are reserved for issuance (except
for the OCA Options  listed in the  Disclosure  Schedule) and there are no other
warrants,  convertible  instruments or other rights,  agreements or commitments,
contingent or otherwise,  obligating OCA to issue,  sell or purchase stock.  The
books and records of the OCA are complete and correct and accurately reflect the
conduct of the Business and affairs of OCA.

          (c)  Subsidiaries.  OCA has no  subsidiaries.  OCA is not a partner or
joint  venturer  with any other  person;  and is not subject to any  obligation,
contingent or otherwise,  to provide funds to or make an investment (in the form
of a loan, capital contribution or otherwise) in any entity.

          (d) Authority.  Subject to shareholder approval,  which will be sought
in accordance  with  applicable  Massachusetts  law, OCA has full right,  power,
capacity  and  authority  to execute,  deliver and perform  this  Agreement,  to
execute,  deliver  and  file  the  Articles  of  Merger  and to  consummate  the
transactions  contemplated  thereby.  The  Board

on the part of OCA,  subject only, in respect of the consummation of the Merger,
to approval by the  shareholders  of OCA holding 66_% in voting  interest of the
outstanding  OCA Shares.  This Agreement has been duly and validly  executed and
delivered  by OCA and  constitutes  the  valid  and  binding  obligation  of OCA
enforceable against it in accordance with its terms. Upon execution and delivery
for filing of the Articles of Merger, the Articles of Merger will have been duly
executed and delivered for filing by OCA.

     Neither the  execution,  delivery and  performance of this  Agreement,  the
delivery  for  filing of the  Articles  of Merger  nor the  consummation  of the
transactions  contemplated  hereby  will  (i)  conflict  with  or  result  in  a
violation,  breach,  termination or acceleration of, or default (or would result
in a violation, breach, termination,  acceleration or default with the giving of
notice or  passage  of time,  or both)  under any of the  terms,  conditions  or
provisions of OCA's Articles of Organization or Bylaws,  each as amended,  or of
any note, bond, mortgage,  indenture,  license, agreement or other instrument or
obligation  to which OCA is a party or by which it or any of its  properties  or
assets may be bound or  affected;  (ii)  result in the  violation  of any order,
writ, injunction,  decree,  statute, rule or regulation applicable to OCA or its
properties or assets;  (iii) result in the imposition of any lien,  encumbrance,
charge or claim  upon any of OCA's  assets;  or (iv)  entitle  any  employee  to
severance  or  other  payments  by OCA or  create  any  other  obligation  to an

or the consummation of the transactions contemplated hereby.

          (e) Financial Statements.  OCA has delivered to OCLI true and complete
copies  of: (i) the  unaudited  balance  sheet of OCA as of March 31,  1996 (the
"Balance Sheet") and the unaudited statements of earnings and cash flows for OCA
for the nine-month  period ended March 31, 1996,  (ii) the audited balance sheet
of OCA as of June 30, 1994 and 1995 and the audited  statements  of earnings and

of OCA and its  Subsidiary  as of June  30,  1993 and the  audited  consolidated
statements  of earnings and cash flows for OCA and its  Subsidiary  for the same

Statements has been prepared in accordance with GAAP (except as may be indicated
therein  or in the  notes  thereto)  and  complies  as to form  in all  material
respects to the  interpretations  and pronouncements of the Commission,  and the
OCA Financial  Statements  fairly  present the financial  condition,  results of
operations  and cash flows of OCA (and its  Subsidiary,  as indicated) as at the
dates and for the periods indicated.

          (f)  No  Undisclosed  Liabilities;   No  Dealings  with  Shareholders,
Officers,  Directors or Employees.  OCA has no liabilities or obligations of any
nature,  other than those  shown or  required to be shown by GAAP on the Balance
Sheet and those  which have arisen  after the date of the  Balance  Sheet in the
ordinary  course of  business  which are not in the  aggregate  or  individually
material.  OCA does not have any contractual  arrangement with, or commitment to
or from, any of its shareholders,  officers, directors, employees as an entirety
or their  respective  family  members  (other than such as may have been entered
into in the  normal  course of  employment),  including,  without  limiting  the
generality of the foregoing,  any contractual  arrangement or commitment whereby
any of such  persons is directly or  indirectly a joint  investor or  coventurer
with respect to, or owner, lessor, lessee,  licensor or licensee of, any real or
personal property,  tangible or intangible,  owned or used by, or a lender to or
debtor of, OCA.

          (g)  Tax Matters.

               (i) OCA has accurately prepared and duly and timely filed all Tax
Returns that OCA was required to file and that were  required to be filed by OCA
Applied  Optics,  a  California  corporation  and a  former  subsidiary  of  OCA
("OCA-AO") which has been merged into OCA. All such Tax Returns were correct and
complete in all material respects. All taxes owed by OCA and OCA-AO as reflected
on the Tax Returns have been paid when due, other than those being  contested in
good faith and where adequate reserves have been established  therefor. No claim
or inquiry with respect to any material amount of Taxes has ever been made by an
authority  in a  jurisdiction  where OCA and OCA-AO did not file Tax Returns for
any period  ending on or before the  Closing  Date.  There are no liens or other
security interests on any of the assets of OCA that arose in connection with any
failure (or alleged failure) to pay any Tax.

               (ii) OCA has not filed a consolidated return with a company other
than OCA-AO.

               (iii) OCA has  delivered to OCLI true and complete  copies of the
income, franchise, excise, sales, use, property and employment tax returns filed
by OCA and  OCA-AO  with  any  federal,  state,  local or  foreign  governmental
authority  since  January 1, 1989,  together  with all  examination  reports and
statements of deficiencies assessed, proposed in writing to be assessed against,
or agreed to by OCA or OCA-AO.

               (iv) All Taxes of OCA or OCA-AO  attributable  to Tax  periods or
portions thereof ending on or prior to the Effective Date,  including Taxes that
may  become  payable  by OCA or OCA-AO  in  future  periods  in  respect  of any
transactions or sales occurring on or prior to the Effective Date, that have not
yet been paid have, in the aggregate,  been adequately  reflected as a liability
on the books of OCA in accordance with GAAP.

               (v) Without  limiting the  generality of the  foregoing,  OCA and
OCA-AO have withheld or collected and duly paid all Taxes  required to have been
withheld or collected and paid in connection  with payments to foreign  persons,
sales and use Tax  obligations  with respect to any and all states,  and amounts
paid or owing to any employee, independent contractor,  creditor, stockholder or
other person.

                                       13

<PAGE>

               (vi) None of the Tax  Returns  of OCA or OCA-AO  have been or are
being currently audited or examined by any governmental authority,  nor have any
deficiencies for any Tax been asserted against OCA or OCA-AO.

               (vii) There are no  outstanding  agreements or waivers  extending
the statute of limitations applicable to any Tax Return of OCA or OCA-AO for any
period.  Neither OCA nor OCA-AO is currently the beneficiary of any extension of
time within which to file any Tax Return.

               (viii)  Neither  OCA nor  OCA-AO  has filed a consent  under Code
Section 341(f) concerning collapsible  corporations.  Neither OCA nor OCA-AO has
made any  payments,  is  obligated  to make any  payments,  or is a party to any
agreement  that could  obligate it to make any payments  that will be an "excess
parachute  payment"  under Code Section 280G.  Neither OCA nor OCA-AO has been a
United  States  real  property  holding  corporation  within the meaning of Code
Section  897(c)(2)  during  the  applicable  period  specified  in Code  Section
897(c)(1)(A)(ii).  Neither OCA nor OCA-OA has been a passive foreign  investment
company as defined in Code Sections 1291-1297.  OCA and OCA-AO have disclosed on
their  federal  income Tax Returns all  positions  taken therein that could give
rise to a substantial understatement of federal income Tax within the meaning of
Code Section  6662.  Neither OCA nor OCA-AO is a party to any Tax  allocation or
sharing  agreement.  Neither OCA nor OCA-AO has  liability  for any Taxes of any
person (other than any of OCA and OCA-AO) under Treas. Reg. Section 1.1502-6 (or
any similar provision of federal, state, local, or foreign law), as a transferee
or successor, by contract, or otherwise.

          (h) Properties; Environmental, Health and Safety Matters. OCA operates
only from leased  facilities in Massachusetts and California which are described
in the Disclosure Schedule (the "Properties"),  and owns leasehold  improvements
at the  Properties,  the book values of which are included in the Balance Sheet.
OCA has good, full and marketable title to, or a valid and continuing  leasehold
interest in, all personal properties and assets,  reflected on the Balance Sheet
or acquired by OCA since the date of the Balance Sheet (except personal property
leases  terminated,  or personal property sold or otherwise  disposed of, in the
ordinary course of business since the date of the Balance Sheet), free and clear
of all liens,  attachments,  pledges,  encumbrances or security interests of any
nature whatsoever,  except for liens for taxes not yet due and the rights of any
lessor  under any lease to which  OCA is a party.  OCA has never  owned any real
estate. All leases 

                                       14
<PAGE>

pursuant to which OCA leases real or personal property are in good standing, and
are valid and in full  force and  effect in  accordance  with  their  respective
terms.  There are no defaults under any such leases  attributable to OCA, and no
event has  occurred  that  (whether or not with  notice,  lapse of time or both)
would constitute a default. All buildings,  improvements,  machinery, equipment,
vehicles and items of tangible  personal  property used in connection with OCA's
operations are structurally  sound, are in good operating  condition and repair,
are  adequate  for the uses to which  they are  being put and are not in need of
maintenance or repairs except for ordinary, routine maintenance.

     To OCA's  knowledge,  the  Disclosure  Schedule  sets forth or describes in
reasonable  detail with respect to the Properties and to OCA's  operations since
May 13, 1985:

ground or subsurface or into groundwater or surface waters;

               (iv) any  evidence  which  has been  observed  by OCA,  including

against OCA seeking or alleging money damages  (resulting  from injury to person
or property),  injunctive relief, remedial action, fines, penalties or any other
remedy  by  reason  of (1) OCA's  violation  of or  noncompliance  with any law,
regulation,  rule or requirement  of law or regulation  relating to pollution or
protection of the environment

thereunder; or (2) OCA's disposal,  discharge or release of Hazardous Materials,

RCRA and by comparable  state laws, and notices and reports made by OCA pursuant
to Sections 302, 311, 312 and 313 of Title III of the Superfund  Amendments  and
Reauthorization Act of 1986 and comparable state laws;

OCA ;

               (xiii)  All  reports  of  environmental  assessments,  surveys or
analyses  conducted by or on behalf of OCA addressing the operational  safety of
the Properties and/or activities  (e.g.,  transportation)  of OCA and/or hazards
and risks (including risk of episodic releases and impact of routine, continuous
releases)  associated  therewith,  including  but not  limited to  process  risk
surveys,   operational  safety  surveys,   air  emissions  modeling,   and  risk
assessments, and action plans and progress reports of OCA responding to any such
reports;

               (xiv) A  description  of the manner in which  asbestos  was or is

Environmental  Laws and laws,  regulations  or ordinances  relating to building,

                                       17

<PAGE>

to the Properties.  The Properties have not been polluted or  contaminated,  nor
have  the  Properties  ever  been  the  subject  of  environmental  clean-up  or
remediation.  The  Properties do not contain any Hazardous  Material (as defined
below), nor has any Hazardous  Material been discharged or spilled thereon.  OCA
has never owned or  operated a  petroleum  or  hazardous  waste  landfill or any
petroleum or other  hazardous  waste  treatment,  storage or disposal  facility.
There are no past or  present  events,  conditions,  circumstances,  activities,
practices,  incidents,  actions  or plans of OCA  which  may  interfere  with or
prevent continued compliance,  or which may give rise to any common law or legal
liability,  or otherwise form the basis of any claim, action, suit,  proceeding,
hearing,  or  investigation,  based  on or  related  to the  disposal,  storage,
handling, manufacture,  processing,  distribution, use, treatment, or transport,
or the emission,  discharge, release or threatened release into the environment,
of any pollutant or waste. There are no proceedings  affecting the Properties or
threatened  which could have an adverse effect on the present or expected future
use of any such  property  for the  purposes  for which it was  acquired  or the
purpose  for which it is used.  The  Properties  have not been on any federal or
state  "Superfund"  list or on EPA's  Comprehensive  Response,  Compensation and
Liability  Information  System  ("CERCLIS")  list  or  on  any  analogous  state
environmental agency list. OCA has not received any notice from any governmental
agency or other party seeking any  information  or alleging any  liability  with
regard  to  the  Properties  or  with  regard  to  any  off-site   environmental
conditions.  The Properties are not subject to any lien under any  Environmental
Laws for which OCA is responsible.

     For purposes of this  Agreement,  "Hazardous  Material" means any petroleum
product or any flammable, explosive or radioactive material, or any hazardous or
toxic waste,  substance or material,  including substances defined as "hazardous
substances",  "hazardous  materials",  "solid waste" or "toxic substances" under
any applicable laws relating to hazardous or toxic materials and substances, air
pollution (including noise and odors), water pollution,  liquid and solid waste,
pesticides,  drinking water,  community and employee health,  environmental land
use management,  stormwater,  sediment control, nuisances,  radiation, wetlands,
endangered species,  environmental  permitting and petroleum  products,  and may
include,  but  not be  limited  to,  the  Federal  Insecticide,  Fungicide,  and
Rodenticide  Act, as amended;  the TSCA;  the CWA;  the  National  Environmental
Policy Act, as amended; the Solid Waste Disposal Act, as amended; the CERCLA, as
amended;  the Clean Air Act, as

                                       18

<PAGE>

amended; the Emergency Planning and Community Right-to-Know Act, as amended; the
Occupational   Safety  and  Health   Act,  as   amended;   Hazardous   Materials
Transportation  Act,  as  amended;  and all  rules and  regulations  promulgated
pursuant to such federal, state, and county and foreign laws and ordinances.

          (i) Accounts  Receivable.  All OCA's accounts and notes  receivable of
OCA shown on the Balance Sheet and all accounts and notes receivable acquired by
OCA subsequent to the date of the Balance Sheet to the date hereof are valid and
enforceable, are not subject to any defense, set-off,  counterclaim or claim for
refund,  have arisen in the ordinary course of business and have been collected,
or are in the process of collection and are  collectible in the ordinary  course
of business and in any event within six months from the  Effective  Date, in the
aggregate recorded amounts thereof,  less the applicable allowances reflected on
the  Balance  Sheet with  respect to the  accounts  and notes  receivable  shown
thereon,  or set up on a basis which is  consistent  with past practice on OCA's
books with respect to the accounts and notes receivable  acquired  subsequent to
the date of the Balance Sheet.

          (j) Purchase and Sale Commitments. No outstanding purchase commitments
by OCA are in excess of the  normal,  ordinary  and  usual  requirements  of the
Business  of OCA,  and the  aggregate  of the  contract  prices to which OCA has
agreed in any outstanding purchase commitments is not so excessive when compared
with current  market  prices for the  relevant  commodities  or services  that a
material loss is likely to result.  No  outstanding  commitment by OCA obligates
OCA to sell any  product  or  service at a price  which,  because  of  currently
prevailing and projected costs of materials or labor, is likely to result in the
period  beginning  with the date of the Balance  Sheet and ending June 30, 1997,
when all such sales commitments are taken in the aggregate for such period, in a
loss to OCA. There are no suppliers to OCA of significant goods or services with
respect  to  which  practical  alternative  sources  of  supply,  or  comparable
products, are not available on comparable terms and conditions.

          (k) Governmental Authorizations.  Set forth on the Disclosure Schedule
is a complete and accurate list of all material governmental permits,  licenses,
franchises,  concessions,  zoning variances and other approvals,  authorizations
and orders  which have been  obtained in  connection  with OCA's  conduct of its
present  Business.  Such  permits,  licenses,  franchises,  concessions,  zoning
variances,  approvals,  authorizations  and orders  constitute

                                       19

<PAGE>

all governmental permits, licenses, franchises,  concessions,  zoning variances,
approvals,  authorizations  and orders which are required  under all  applicable
local,  state,  federal or foreign laws and regulations for the operation of the
Business being  conducted by OCA as it has been heretofore  conducted.  All such
permits,  licenses,  franchises,   concessions,   zoning  variances,  approvals,
authorizations  and orders are  presently  in full force and  effect,  OCA is in
material  compliance  with  the  requirements  thereof  (except  for  immaterial
violations  that are unlikely to result in a suspension or forfeiture  thereof),
no suspension or  cancellation  of any of them is  threatened,  the delivery for
filing  of the  Articles  of  Merger  and  the  Certificate  of  Merger  and the
consummation   of  the  Merger  will  not  adversely   affect  the  validity  or
effectiveness  of, and will not require,  for retention thereof after the change
of ownership resulting from the Merger, the consent or approval of any party to,
or any other person or  governmental  agency  having  jurisdiction  of, any such
permit, license, franchise, concession, zoning variance, approval, authorization
or order. OCA has no knowledge of any fact or circumstance  which would prevent,
limit or restrict  OCA from  continuing  to operate its  Business in the present
manner, and no new material  requirements  pertaining to the manner of operating
its current Business have been issued or announced by any governmental authority
since January 1, 1995,  nor are there any disputes  pending  between OCA and any
governmental authority about OCA's current operations,  and OCA has furnished or
made  available  to OCLI  all  reports  and  applications  filed by OCA with any
governmental agency since January 1, 1993.

          (l) Patents; Trademarks. OCA solely owns or has the right to use, free
and clear of any obligation of payment, encumbrance, lien or claim, all patents,
patent and know-how  licenses,  trademarks,  trade names,  service marks,  brand
names and copyrights,  and registrations and applications therefor,  used in the
conduct of its Business or the use of which is necessary for its Business as now
being conducted (the  "Intangibles").  OCA owns or possesses  adequate rights to
use, free and clear of any  obligation of payment,  encumbrance,  lien or claim,
all  inventions,  technology,  technical  know-how,  processes,  designs,  trade
secrets,  vendor and customer lists and other confidential  information required
for or used in its current Business.  To the extent that OCA has provided to the
U.S. Government any trade secrets, know how, or proprietary data, OCA has marked
such trade secrets,  know how, and  proprietary  data with adequate  restrictive
legends which identify such as either "restricted computer software" or "limited
rights 

                                       20

data," as those terms are defined in the Federal Acquisition Regulations ("FAR")
at Subpart 27.4.  To the extent that OCA has provided to any third party,  other
than the U.S. Government, any trade secrets, know how, or proprietary data, such
information has been provided subject to an adequate non-disclosure agreement or
obligation.  No person has made any claim or demand upon OCA  pertaining to, and
no proceeding is pending or threatened,  which  challenges (i) the rights of OCA
in respect  of any  Intangibles  or (ii) the  rights of OCA to any  confidential
information  or trade  secrets used in the conduct of its current  Business.  No
Intangible owned or used by OCA in its current Business is subject to any order,
ruling,  decree,  judgment or  stipulation  by or with any court,  arbitrator or
administrative  agency which is materially adverse to OCA's current Business. No
person  has made any claim or demand  upon OCA,  infringed,  or  engaged  in the
unauthorized use of, any patent, trademark, trade name, service mark, brand name
or copyright, or any invention, technology, technical know-how, process, design,
trade secret or other intellectual property of another. There is no infringement
or  unauthorized  use by a third  party of any  patent,  trademark,  trade name,
service mark, brand name or copyright, or any invention,  technology,  technical
know-how,  process, design, trade secret or other intellectual property owned or
used by OCA. Each technical or managerial  employee of OCA is bound by the terms
of  an  Employee  Patent  and  Confidential  Information  Agreement  or  similar
agreement, a copy of which has been supplied to OCLI.

          (m) Government  Property;  Accounting for  Government  Contracts.  The
Disclosure  Schedule  contains an accurate list of the type and location of each
item  of  property  owned  or  furnished  directly  or  indirectly  by the  U.S.
Government or by  non-government  customers to be used by OCA in connection with
the performance of prime contracts or  subcontracts  for the U.S.  Government or
any  agency  or   department   thereof  or,  as  the  case  may  be,  for  other
non-government  customers;  in each case where the  original  acquisition  price
exceeded $10,000. All such property is present at the location so indicated,  is
in as good condition as when originally furnished,  except for ordinary wear and
tear, and is being accounted for pursuant to applicable  Federal  regulations or
customer  requirements.  OCA has claimed  reimbursement under contracts with the
U.S. Government only for costs which are allowable, including costs specifically
allowed by FAR Part 31,  entitled  "Contract Cost  Principles  and  Procedures."
OCA's  cost  accounting  system  complies  with  GAAP,  and the Cost  Accounting
Standards,  as promulgated by the Cost Accounting 

                                       21
<PAGE>

Standards  Board and  reflected  in Appendix B to the FAR.  OCA has not made any
changes to its  accounting  practices  that would  require  submission of a cost
impact  proposal to the U.S.  Government  and no cost impact  proposal  has been
requested by the U.S.  Government.  There are no pending or threatened audits by
the Defense  Contracts  Audit Agency or other  government  audit authority under
which allowance and allocation of cost and/or accounting for cost is at issue or
that could lead to the  disallowance of repayment of any material monies already
received.

          (n)  Insurance.  All policies of insurance  owned by OCA are listed on
the Disclosure Schedule.  OCA (i) is not in default with respect to any material
provision  of any policy of general  liability,  fire or other form of insurance
held by it; (ii) is current in the payment of all  premiums  due or has reserved
for such premiums due on such  insurance,  and has not failed to give any notice
or present any claim  thereunder  in due and timely  fashion,  except for claims
that are  immaterial  in both the  nature of the claim and in the amount of such
claim;  (iii)  maintains  insurance  on all  of  its  assets  and  its  Business
(including  products  liability  insurance)  from insurers which are financially
sound and reputable, in amounts and coverages and against the kinds of risks and
losses reasonably  prudent to be insured against by corporations  engaged in the
same or similar  businesses;  (iv) no basis  exists which would  jeopardize  the
coverage  under  any such  insurance;  and (v)  under  the  terms of the  policy
relating thereto, no such insurance will be automatically terminated or canceled
by reason of the  execution,  delivery and  performance of this Agreement or the
consummation of the transactions contemplated hereby.

     Except as disclosed in the Disclosure Schedule:

     OCA does not  maintain or  contribute  to any  Pension  Plan or any Welfare
Plan,  nor has OCA or any of OCA's ERISA  Affiliates  ever had, an obligation to
contribute to any Multiemployer Plan. All Pension Plans and Welfare Plans of OCA
have been  administered  in  compliance  with  their  terms,  ERISA  and,  where
applicable,  the Code.  OCA has applied to the  Internal  Revenue  Service for a
favorable  determination  letter with respect to the  qualification of each such
Pension Plan which is intended to qualify under  Section  401(a) of the Code and
the exemption of any  corresponding  trust. A copy of each such  application has
been  furnished to OCLI,  and OCA has no reason to believe  that such  favorable
determination letters will not be issued in the ordinary course. With respect to
each Pension Plan:  (1) there is no fact,  including,  without  limitation,  any
Reportable Event,  that exists that would constitute  grounds for termination of
such Plan by the PBGC or for the  appointment by the  appropriate  United States
District  Court  of  a  trustee  to  administer  such  plan,  in  each  case  as
contemplated  by  ERISA;   (2)  neither  OCA  nor  any  fiduciary,   trustee  or
administrator  of any Pension Plan or Welfare Plan has engaged in any Prohibited
Transaction that could subject OCA to any tax or any penalty imposed by ERISA or
the Code;  (3) OCA has no  liability  to the PBGC  (other  than for  payment

                                       25

<PAGE>

of premiums); and (4) there is no Accumulated Funding Deficiency with respect to
any Pension Plan maintained by OCA or any of OCA's ERISA Affiliates,  whether or
not waived.

     No Pension Plan or Welfare Plan, OCA or any of OCA's ERISA  Affiliates,  or
any "party in interest" or  "disqualified  person" (as such terms are defined in
Section 3 of ERISA and  Section  4975 of the Code) with  respect to any  Pension
Plan  or  Welfare  Plan  has  taken  any  action  including  the  making  of any
investment,  or failed to take any action, that could subject any of them or any
other person to any liability  for any tax or for breach of fiduciary  duty with
respect to or in  connection  with any Pension Plan or Welfare  Plan. No Pension
Plan or Welfare Plan,  administrator or fiduciary of any Pension Plan or Welfare
Plan, or OCA has any  liability  under any  provision of any  applicable  law by
reason of any  communication  or failure to  communicate  with  respect to or in
connection  with any Pension Plan or Welfare  Plan,  or any filing or failure to
file  with  any   governmental   entity.   No  Pension  Plan  or  Welfare  Plan,
administrator or fiduciary of any Pension Plan or Welfare Plan, or OCA or any of
OCA's ERISA Affiliates has any liability to any plan participant, beneficiary or
other person under any provision of any  applicable law by reason of any payment
of benefits or other amounts or failure to pay benefits or any other amounts, or
by reason of any  credit or failure to give  credit for any  benefits  or rights
(such as, but not limited to, vesting  rights) with respect to benefits under or
in connection  with any Pension Plan or Welfare Plan,  other than benefit claims
in the normal  administration  of each Pension Plan or Welfare Plan.  OCA is not
delinquent  or in  arrears  on any  amounts  owed  to,  or with  respect  to any
contributions  under,  any  Pension  Plan  or  Welfare  Plan.  No  person  is  a
participant in or eligible for participation  (without regard to age or service)
in, any Pension Plan or Welfare Plan who is not a present or former  employee of
OCA or a  beneficiary  of such  Pension Plan or Welfare  Plan.  Except as may be
required  by  the  Consolidated  Omnibus  Budget   Reconciliation  Act  of  1985
("COBRA"),  none of the Pension Plans or Welfare Plans  provides for  continuing
accrual  of  benefits  or  coverage  for any  participant  or  beneficiary  of a
participant after such participant's termination of employment with OCA.

     Except to the extent COBRA  requires OCA to offer health  insurance and OCA
incurs administrative costs, there are no unfunded obligations under any Pension
Plan or Welfare Plan providing  benefits after  termination of employment to any
employee of OCA (or beneficiary  thereof),  including without limitation retiree
health coverage and deferred  

                                       26

<PAGE>

compensation.  There has been no Plan  Termination  that has occurred during the
five-year period ending on the date hereof.  OCA has no liability incurred under
Title IV of ERISA by OCA with respect to any Pension Plan  maintained by a trade
or business (whether or not incorporated) which is under common control with, or
part of a controlled  group of  corporations  with,  OCA,  within the meaning of
Sections  414(b) or (c) of the  Code.  No event has  occurred  and no  condition
exists with respect to any Pension  Plan or Welfare Plan that would  subject OCA
to any tax  under  Section  4972,  4977,  4979 or 4980B of the Code or to a fine
under ERISA  Section  502(c) with  respect to any such plan.  No Welfare Plan is
funded with a trust or other funding vehicle,  other than insurance policies. No
Welfare Plan or Pension Plan,  plan  documentation  or  agreement,  summary plan
description or other written  communication  distributed to employees  prohibits
OCA from amending or terminating  any such plan.  There has occurred no Complete
Withdrawal or Partial  Withdrawal  with respect to any  Multiemployer  Plan that
could cause OCA to incur any liability  under or as a result of ERISA other than
to the extent  previously  paid or fully provided for in the Balance Sheet,  and
all  payments  required to be made to any such Plan by OCA under any  applicable
collective  bargaining  agreements have been made. As of the date of the Balance
Sheet, OCA had no liability in connection with any Pension Plan, Welfare Plan or
other  employee  benefit  plan which was not fully  provided  for on the Balance
Sheet. There are no actions,  arbitration's or claims pending or threatened with
respect to any Pension Plan, Welfare Plan or other employee benefit plans or any
fiduciary or sponsor thereof.

contemplating the termination for convenience of any executory or unexpired U.S.
Government contract referred to in Section 3.2(p)(ii).

agency, or any governmental  investigation,  suspension or debarment proceeding,
nor  does  any  basis  for any  claim or legal  action  or other  proceeding  or

expected materially and adversely to affect, the Business, Properties, assets or
financial condition of OCA taken as a whole.

          (u) Corporate Practices.  OCA has never,  directly or indirectly:  (i)
used any corporate funds for unlawful  contributions,  gifts,  entertainment  or
other unlawful expenses relating to political  activity;  (ii) made any unlawful

(viii) submitted,  or caused to be submitted,  any false claims against the U.S.
Government or (ix) made, or caused to be made, any false  statements to the U.S.
Government subject to prosecution under 18 U.S.C. Section 1001.

          (v) Labor  Matters.  There  are no  collective  bargaining  agreements
covering  any of OCA's  employees.  There  are no labor  organizing  activities,
election petitions or proceedings, disputes, slowdowns, work stoppages or unfair
labor practice  complaints  pending or threatened against OCA or between OCA and
any of its employees,  nor have there been any such activities or  controversies
within the three  years prior to this  Agreement.  No labor  grievance  has been
filed and no  arbitration  proceeding  has arisen  and is  pending  and no claim
therefor has been asserted.

          (w) Brokers and Finders.  OCA has not  employed  any broker,  agent or

          (aa) Pooling Accounting.  OCA and, to the best of OCA's knowledge, the
Shareholders  have taken no actions that would prevent OCLI from  accounting for
the Merger as a pooling-of-interests for accounting purposes.

          (bb) Continuity of Interest. To the best of OCA's knowledge,  there is
no plan or  intention  on the  part of the  Shareholders  to sell,  exchange  or
otherwise  dispose of a number of shares of OCLI  Shares  received in the Merger
that  would  reduce  the  Shareholders'  ownership  of OCLI stock to a number of
shares  having a value,  as of the  Effective  Date,  of less than fifty percent
(50%) of the  value of all of the  formerly  outstanding  stock of OCA as of the
same date.  For  purposes  of this  representation,  shares of OCA Common  Stock
surrendered by dissenters or exchanged for cash or in lieu of fractional  shares
of OCLI  Common  Stock will be treated as  outstanding  OCA Common  Stock on the
Effective Date.  Moreover,  shares of OCA Common Stock and shares of OCLI Common
Stock held by the  Shareholders  and otherwise  sold,  redeemed,  or disposed of
prior  or   subsequent   to  the  Merger  will  be  considered  in  making  this
representation.

          (cc) Expenses. The Disclosure Schedule sets forth a description of all
fees and expenses  OCA has paid or incurred as of the date hereof in  connection
with the transactions contemplated hereby.

          (dd)  Statements  True  and  Correct;   Further   Representations  and
Warranties.  This Agreement (including the Disclosure Schedule and any documents
described  herein or in the Disclosure  Schedule and delivered  pursuant hereto)
does not contain any untrue  statement  of a material  fact or omit any material
fact required to be stated herein or therein or necessary to make the statements
contained herein or therein,  in the light of the circumstances under which they
were made, not misleading.

     3.3.  Representations  and  Warranties  of OCLI and  Acquisition.  OCLI and
Acquisition  represent  and  warrant to OCA that except as set forth in the OCLI
SEC Documents (as defined in Section  3.3(c) below) or the  Disclosure  Schedule
attached  as  Exhibit  F  (the  "OCLI  Disclosure  Schedule")  and  specifically
identifying the relevant subsection thereof:

          (a)  Organization  and  Good  Standing.  OCLI  is a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Delaware,  and has all requisite corporate power and authority to own, lease and
operate  its  properties  and to  carry  on  its  business  as it is  now  being
conducted.  Acquisition is a corporation 

                                       35

<PAGE>

duly  organized,  validly  existing and in good  standing  under the laws of the
State of Delaware,  and has all requisite corporate power and authority to carry
on its  business as it is now being  conducted.  OCLI has  delivered  to OCA the
Certificate of Incorporation,  as amended to date, of both OCLI and Acquisition.
OCLI and Acquisition are duly qualified to do business as a foreign corporation,
and are in good  standing,  in each  jurisdiction  in which the character of the
properties owned, operated or leased by the respective corporation or the nature
of the  respective  corporation's  activities  is such that  qualification  as a
foreign corporation is required by applicable law.

          (b) Authority.  Each of OCLI and  Acquisition  has full right,  power,
capacity  and  authority  to execute,  deliver and perform  this  Agreement,  to
consummate the transactions  contemplated  hereby and in the case of Acquisition
to execute,  deliver  and file the  Articles  of Merger and the  Certificate  of
Merger.  The  execution  and  delivery  hereof,  and  the  consummation  of  the
transactions  contemplated  hereby, have been duly and validly authorized by all
necessary  corporate  action  on the  part of OCLI  and  Acquisition,  and  this
Agreement  constitutes  the valid and  legally  binding  obligation  of OCLI and
Acquisition  enforceable  in accordance  with its terms.  Neither the execution,
delivery  and  performance  of this  Agreement,  the  delivery for filing of the
Certificate  of Merger nor the  consummation  of the  transactions  contemplated
hereby will (i)  conflict  with or result in a violation,  breach,  termination,
acceleration   of,  or  default  (or  would  result  in  a  violation,   breach,
termination,  acceleration  or  default  with the giving of notice or passage of
time or both) under any of the terms, conditions or provisions of the respective
charter documents or Bylaws of OCLI or Acquisition,  each as amended,  or of any
note,  bond,  mortgage,  indenture,  license,  agreement or other  instrument or
obligation  to  which  OCLI or  Acquisition  is a  party,  or by  which  OCLI or
Acquisition  or any of their  respective  properties  or assets  may be bound or
affected,  (ii) to the knowledge of OCLI,  result in the violation of any order,
writ,  injunction,  decree,  statute,  rule or regulation  applicable to OCLI or
Acquisition,  or their respective  properties or assets,  or (iii) result in the
imposition of any lien, encumbrance, charge or claim upon any of OCLI's assets.

     Except for a filing under the  Antitrust  Improvements  Act, the filing and
effectiveness  of the Registration  Statement with the Commission,  the delivery
for  filing  of the  Articles  of  Merger  with  the  Secretary  of State of the
Commonwealth  of  Massachusetts   and  the  delivery  for  filing  by

governmental  authority  or  third  party is  required  in  connection  with the
execution,  delivery and performance of this Agreement by OCLI or Acquisition or
the consummation of the transactions contemplated hereby.

          (c) SEC Documents.  OCLI has delivered to OCA true and complete copies
of each report and definitive  proxy statement filed by OCLI with the Commission
since  October 31, 1994 as such  documents  have since the time of their  filing
been amended  (the "OCLI SEC  Documents")  and true and complete  copies of each
exhibit referred to in the OCLI SEC Documents (but without duplication), as such
exhibits  have  since  the time of their  filing  been  amended  (the  "OCLI SEC
Exhibits") which are all the reports,  proxy statements  (other than preliminary
material) and exhibits that OCLI was required to file with the Commission  since
such date. As of their respective dates, the OCLI SEC Documents  complied in all
material respects with the requirements of the Securities  Exchange Act of 1934,
as amended (the "Exchange Act"), and the rules and regulations of the Commission
thereunder  applicable  to such  OCLI  SEC  Documents  and  none of the OCLI SEC
Documents  when filed  contained  any  untrue  statement  of a material  fact or
omitted to state a material fact  required to be stated  therein or necessary to
make the statements  therein,  at the time in light of the  circumstances  under
which they were made, not misleading.  The financial statements of OCLI included
in the OCLI SEC  Documents  complied as to form in all  material  respects  with
applicable  accounting  requirements and with published rules and regulations of
the  Commission  with respect  thereto,  have been prepared in  accordance  with
generally  accepted  accounting  principles applied on a consistent basis during
the periods involved (except as may be indicated therein or in the notes thereto
or, in the case of the  unaudited  statements,  as permitted by Form 10-Q of the
Commission)  and  fairly  present  (subject,   in  the  case  of  the  unaudited

the consolidated results of their operations and cash flows for the periods then

          (d) Capital Stock of OCLI. As of April 30, 1996,  OCLI had authorized,
issued and outstanding the number of shares of capital stock as set forth in the
OCLI Disclosure Schedule.

     All of such shares have been duly authorized and validly issued,  are fully
paid,  non-assessable  and free of preemptive  rights. The offer and sale of all
outstanding  securities of OCLI complied with  applicable  federal and state and
foreign securities laws. The OCLI Shares to be delivered at the Closing pursuant
to this  Agreement are duly  authorized  and, when and if so delivered,  will be
validly issued, outstanding, fully paid and nonassessable.

     On or prior to the Merger,  330,804  shares of OCLI Common  Stock will have
been  reserved for issuance  upon the exercise of the OCA Options  listed in the
Disclosure Schedule, together with such additional shares as may become issuable
pursuant to the  operation of the  anti-dilution  provisions of the OCA Options.
The issuance and delivery of OCLI Shares upon the  completion of the  conversion
described in Section 1.2 of the Agreement  will not require an adjustment in the
number of shares  issuable  upon the exercise of OCLI's  outstanding  securities
which are convertible into or exercisable for shares of OCLI Common Stock.

          (e) Brokers and Finders.  OCLI and  Acquisition  have not employed any
broker,  agent or finder or  incurred  any  liability  for any  brokerage  fees,
agents'  commissions  or  finders'  fees in  connection  with  the  transactions
contemplated hereby.

          (f)  Novation of  Contracts.  OCLI and  Acquisition  acknowledge  that
novation of OCA's U.S. Government  contracts may be required after the Effective
Date.

          (g) No Intent to Sell or Transfer OCA.  OCLI has no present  intention
of selling or otherwise  disposing of the capital  stock of OCA, of any division
of OCA or of any substantial portion of OCA's assets.

          (h) No Changes. There has not been: (i) any material adverse change in
the  financial  condition,  assets,  liabilities  or earnings of OCLI;  (ii) any
material  damage,  destruction  or loss (whether or not covered by insurance) to
OCLI's  properties or the production  equipment located therein which materially
and adversely  affects the financial or operating  condition of OCLI;  (iii) any
statute,  rule or regulation,  or any government policy,  adopted which pertains

                                       38

<PAGE>

particularly  to OCLI's business (and not businesses in general) and which would
materially  and adversely  affect OCLI's  business or assets;  (iv) any material
mortgage, lien, attachment,  pledge, encumbrance or security interest created on
any material  asset,  tangible or  intangible,  of OCLI, or assumed by OCLI with
respect  to any such  asset,  except  for liens  for taxes not yet due,  and for
equipment  leases and  purchase  money  security  interests  entered into in the
ordinary course of business.

          (i) Employee  Benefit Plans.  For the purposes of this Section 3.3(i),
the definitions as set forth in Section 3.2(o) shall apply.  Except as disclosed
in the Disclosure Schedule:

     OCLI does not  maintain or  contribute  to any Pension  Plan or any Welfare
Plan, nor has OCLI or any of OCLI's ERISA  Affiliates ever had, an obligation to
contribute  to any  Multiemployer  Plan.  All Pension Plans and Welfare Plans of
OCLI have been  administered  in compliance  with their terms,  ERISA and, where
applicable,  the Code.  OCLI has applied to the Internal  Revenue  Service for a
favorable  determination  letter with respect to the  qualification of each such
Pension Plan which is intended to qualify under  Section  401(a) of the Code and
the exemption of any  corresponding  trust. A copy of each such  application has
been  furnished to OCA,  and OCLI has no reason to believe  that such  favorable
determination letters will not be issued in the ordinary course. With respect to
each Pension Plan:  (1) there is no fact,  including,  without  limitation,  any
Reportable Event,  that exists that would constitute  grounds for termination of
such Plan by the PBGC or for the  appointment by the  appropriate  United States
District  Court  of  a  trustee  to  administer  such  plan,  in  each  case  as
contemplated  by  ERISA;  (2)  neither  OCLI  nor  any  fiduciary,   trustee  or
administrator  of any Pension Plan or Welfare Plan has engaged in any Prohibited
Transaction  that could subject OCLI to any tax or any penalty  imposed by ERISA
or the Code;  (3) OCLI has no  liability  to the PBGC (other than for payment of
premiums);  and (4) there is no Accumulated  Funding  Deficiency with respect to
any Pension Plan maintained by OCLI or any of OCLI's ERISA  Affiliates,  whether
or not waived.

     No Pension Plan or Welfare Plan, OCLI or any of OCLI's ERISA Affiliates, or
any "party in interest" or  "disqualified  person" (as such terms are defined in
Section 3 of ERISA and  Section  4975 of the Code) with  respect to any  Pension
Plan  or  Welfare  Plan  has  taken  any  action  including  the  making  of any
investment,  or failed to take any action,

                                       39

<PAGE>

that could  subject any of them or any other person to any liability for any tax
or for  breach of  fiduciary  duty with  respect  to or in  connection  with any
Pension Plan or Welfare Plan. No Pension Plan or Welfare Plan,  administrator or
fiduciary of any Pension Plan or Welfare Plan,  or OCLI has any liability  under
any provision of any applicable law by reason of any communication or failure to
communicate  with respect to or in  connection  with any Pension Plan or Welfare
Plan, or any filing or failure to file with any governmental  entity. No Pension
Plan or Welfare Plan,  administrator or fiduciary of any Pension Plan or Welfare
Plan,  or OCLI or any of OCLI's ERISA  Affiliates  has any liability to any plan
participant,  beneficiary  or other person under any provision of any applicable
law by reason of any  payment  of  benefits  or other  amounts or failure to pay
benefits  or any other  amounts,  or by reason of any  credit or failure to give
credit for any benefits or rights (such as, but not limited to, vesting  rights)
with respect to benefits under or in connection with any Pension Plan or Welfare
Plan,  other than benefit  claims in the normal  administration  of each Pension
Plan or Welfare Plan.  OCLI is not  delinquent or in arrears on any amounts owed
to, or with  respect to any  contributions  under,  any Pension  Plan or Welfare
Plan.  No person is a  participant  in or eligible  for  participation  (without
regard to age or  service)  in, any  Pension  Plan or Welfare  Plan who is not a
present or former  employee of OCLI or a  beneficiary  of such  Pension  Plan or
Welfare  Plan.  Except as may be required  by the  Consolidated  Omnibus  Budget
Reconciliation Act of 1985 ("COBRA"), none of the Pension Plans or Welfare Plans
provides for continuing  accrual of benefits or coverage for any  participant or
beneficiary of a participant after such participant's  termination of employment
with OCLI.

     Except to the extent COBRA requires OCLI to offer health insurance and OCLI
incurs administrative costs, there are no unfunded obligations under any Pension
Plan or Welfare Plan providing  benefits after  termination of employment to any
employee of OCLI (or beneficiary thereof),  including without limitation retiree
health coverage and deferred  compensation.  There has been no Plan  Termination
that has occurred  during the five-year  period ending on the date hereof.  OCLI
has no  liability  incurred  under Title IV of ERISA by OCLI with respect to any
Pension Plan  maintained  by a trade or business  (whether or not  incorporated)
which  is  under  common  control  with,  or  part  of  a  controlled  group  of
corporations  with,  OCLI,  within the meaning of Sections  414(b) or (c) of the
Code. No event has occurred and no condition  exists with respect to any Pension
Plan or Welfare  Plan that would  subject  OCLI to any tax under  Section  4972,

                                       40

<PAGE>

4977,  4979 or 4980B of the Code or to a fine under  ERISA  Section  502(c) with
respect  to any such  plan.  No  Welfare  Plan is  funded  with a trust or other
funding vehicle, other than insurance policies. No Welfare Plan or Pension Plan,
plan  documentation  or  agreement,  summary plan  description  or other written
communication   distributed  to  employees   prohibits  OCLI  from  amending  or
terminating any such plan. There has occurred no Complete  Withdrawal or Partial
Withdrawal with respect to any Multiemployer Plan that could cause OCLI to incur
any liability under or as a result of ERISA other than to the extent  previously
paid or fully provided for in the Balance Sheet, and all payments required to be
made to any  such  Plan by  OCLI  under  any  applicable  collective  bargaining
agreements  have been made.  As of the date of the  Balance  Sheet,  OCLI had no
liability in connection  with any Pension Plan,  Welfare Plan or other  employee
benefit plan which was not fully provided for on the Balance Sheet. There are no
actions,  arbitration's  or claims  pending or  threatened  with  respect to any
Pension Plan,  Welfare Plan or other employee  benefit plans or any fiduciary or
sponsor thereof.

          (j) Litigation or Proceedings.  OCLI is not engaged in, or a party to,
or to its  knowledge  threatened  with,  any  claim  or  legal  action  or other
proceeding  before any court,  any arbitrator of any kind or any  administrative
agency, or any governmental  investigation,  suspension or debarment proceeding,
nor, to OCLI's knowledge , does any basis for any claim or legal action or other

statement of a material fact  contained in the  Registration  Statement or Proxy
Materials or any  amendment or  supplement  thereto or omits to state a material
fact necessary in order to make any statement therein not misleading. OCLI shall
advise OCA,  promptly after OCLI receives notice  thereof,  of the time when the

          (a) OCLI  currently  intends to maintain  all material  Pension  Plan,
Welfare  Plans  and  other  OCA  employee  benefit  plans  or  programs  without
significant modification after the Closing.  Notwithstanding the foregoing, OCLI
expressly  reserves the right to modify or terminate any Pension  Plan,  Welfare
Plan or other OCA  benefit  plan or  program,  at any time or from time to time,
except that no such  modification  shall effect a change in coverage or level of
benefit which would be any less advantageous to the covered employees or retired
employees  than the most  advantageous  coverage or level of benefit at the time
maintained by OCLI for any other similarly constituted group of its employees or
retired employees.

          (b) Except as may be otherwise  required by ERISA,  OCLI will give OCA

participate  in any  employee  plan  adopted  from  time  to time  by  OCLI,  in
accordance with the terms thereof.

     4.8. Expenses.  Each party will bear entirely the respective  out-of-pocket
expenses that it incurs in connection with the transactions  contemplated hereby
including legal and accounting fees. Notwithstanding the foregoing, this Section
4.8 shall not be construed as relieving  any party from any  liability  which it

herein.

          (a) OCA upon its  demand  shall  be  indemnified  by OCLI for the full
amount of all damages (as defined below)  suffered by it as a direct or indirect
result of:

               (i) the inaccuracy of any representation or warranty made by OCLI
in or pursuant to this Agreement,  in the form and to the extent so made, or the
omission of any material fact relating thereto; and

               (ii) any failure by OCLI to perform any obligation or comply with
any covenant or agreement  specified in this  Agreement or in any other document
executed at the Closing.

          (b) For the purpose of this  Agreement,  the term  "damages"  shall be
determined and computed by reference to the actual economic loss to OCA (and not
just by  reference to any effect on the value of the shares of OCA) and shall be
deemed to include all  losses,  liabilities,  expenses or costs  incurred by the
OCA, including reasonable attorneys' fees.

          (c) The right of OCA to be  indemnified  pursuant  to  Section  4.9(a)
shall not apply  until the sum of the damages  suffered  by OCA on a  cumulative
basis equals or exceeds  $250,000,  at which point OCLI shall become  liable for
all damages, not just amounts in excess of $250,000,  and (ii) shall be only for
claims that are asserted by OCA before the date of completion of the first audit
of OCA covering a period  ending  after the  Effective  Date.  In no event shall
OCLI's liability hereunder exceed an amount equal to (i) the aggregate number of
Escrowed  Shares  multiplied by (ii) the Per Share Value of such Escrowed Shares
(as determined in accordance  with the Escrow  Agreement).  Notwithstanding  the
foregoing,  this  Section  4.9(c)  shall not  apply in the event OCA has  actual
knowledge of a breach of a representation or warranty.

                                   ARTICLE VII

                                  REGISTRATION

     7.1. Certain Definitions.  As used in this Article VII, the following terms
shall have the following respective meanings:

     "Commission" shall mean the Securities and Exchange Commission.

     "Holders"  shall mean any  Shareholder  who holds at least Thirty  Thousand
(30,000) Shares.

     "Other  Holders"  shall mean all  holders of OCLI's  securities  other than
Holders.

     "Registration  Expenses" and "Selling  Expenses" shall mean the expenses so
described in Section 7.5.

     "Securities Act" shall mean the Securities Act of 1933, as amended, and the
rules and regulations of the Commission thereunder,  all as the same shall be in
effect at the time.

     "Shares"  shall mean (a) the OCLI Shares (as defined in Section  1.2),  and
(b) any  securities  issued  with  respect to the OCLI Shares by reason of stock
dividends, stock splits, or combinations, recapitalizations,  reorganizations or
other corporate action.

     "Underwriter"   shall  mean  each  person  who  is  or  may  be  deemed  an
"underwriter,"  as that term is defined in Section 2(11) of the Securities  Act,
in respect of  securities  which  shall have been  registered  by OCLI under the
Securities Act pursuant to any of the provisions of this Article 7.

     7.2.  Incidental  Registration.  If OCLI for itself or any of its  security
holders  shall at any time or times on or after  the  Closing  and  prior to two
years from the Closing determine to register under the Securities Act any shares
of its capital stock or other securities  (other than (i) the registration of an
offer and sale of securities to employees of, or other persons providing service
to, OCLI pursuant to an employee or similar benefit plan, registered on Form S-8

                                       57

<PAGE>

or  comparable  form;  or  (ii)  relating  to a  merger,  acquisition  or  other
transaction of the type described in Securities Act Rule 145 or comparable rule,
registered  on Form S-4 or similar  form) OCLI will  notify  each Holder in each
case of such determination at least thirty (30) days prior to the filing of such
registration statement, and upon the request of a Holder given in writing within
twenty (20) days after the effective date of such notice, OCLI will use its best
efforts as soon as practicable  thereafter to cause not more than fifty per cent
(50%) of the Shares  owned by such Holder to be  included  in such  registration
statement. Notwithstanding the foregoing, in the event the proposed registration
is in  whole  or in part  an  underwritten  public  offering,  and the  managing
underwriter  determines  and advises OCLI in writing  that the  inclusion of all
Shares of such  requesting  Holders  and all shares of OCLI's  capital  stock or
other  securities to be offered by it and by Other Holders,  whether  originally
covered by requests for registration or otherwise included, would interfere with
the  marketing  of such  securities,  then the number of shares of OCLI  capital
stock  otherwise  to be included in the  registration  statement  by Holders and
Other  Holders  shall be reduced as  follows:  (1) there shall first be excluded
shares  proposed  to be included by Other  Holders  not  possessing  contractual
rights to include the same and (2) any further reduction shall be pro rata among
such Holders and Other  Holders  (having  such  contractual  rights)  requesting
inclusion of their Shares in such  registration  in the proportion to the number
of shares of OCLI's  capital  stock then owned by each with  respect to which it
has registration rights; provided,  however, that there shall be no reduction in
the number of shares to be included therein by OCLI.

     7.3.  Conditions to Obligation to Register Shares. As a condition to OCLI's
obligation hereunder to cause Shares to be included in a registration statement,
the Holder shall  provide  such  information  and execute such  documents as may
reasonably be required in connection with such registration.

     7.4.  Registration  Procedures.  If and  whenever  OCLI is  required by the
provisions  of this  Article 7 to use its best  efforts  to  include  any of the
Shares in a registration  statement  filed under the Securities Act, OCLI shall,
as expeditiously as possible:

          (a) Prepare and file with the Commission a registration statement with
respect  to such  Shares and use its best  efforts  to cause  such  registration
statement to become and remain effective.

                                       58

<PAGE>

          (b)  Prepare  and  file  with  the  Commission   such  amendments  and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration  statement effective for
ninety  (90)  days  from  the date of its  effectiveness  or  (unless  otherwise
required by the Securities  Act) until the Shares covered  thereunder  have been
sold, whichever is earlier.

          (c) Furnish to each  Holder  such  number of copies of the  prospectus
contained  in  such   registration   statement   (including   each   preliminary
prospectus), in conformity with the requirements of the Securities Act, and such
other documents as such Holder may reasonably request in order to facilitate the
disposition of the Shares owned by such Holder.

          (d) Use its best efforts to register or qualify the Shares  covered by
such  registration  statement  under  the  securities  or blue  sky laws of such
jurisdictions  as each selling Holder shall reasonably  request,  and do any and
all other acts and things  which may be  necessary  or  advisable to enable such
holder to consummate the  disposition of the Shares owned by such Holder in such
jurisdictions during the period specified in 7.4(b).

          (e)  Notify  each  Holder of any Shares  covered by such  registration
statement  at any time when a  prospectus  relating  thereto is  required  to be
delivered  under the Securities Act of the happening of any event as a result of
which  the  prospectus  contained  in such  registration  statement,  as then in
effect,  includes an untrue  statement of a material  fact or omits to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading in the light of the  circumstances  then  existing.  Each
Holder agrees, upon receipt of such notice, forthwith to cease making offers and
sales of the Shares pursuant to such registration statement or deliveries of the
prospectus  contained  therein  for any  purpose  and to  return  to  OCLI,  for
modification  and  exchange,  the  copies  of such  prospectus  not  theretofore
delivered  by such  Holder;  provided,  that OCLI shall  forthwith  prepare  and
furnish,  after  securing such  approvals as may be necessary,  to such Holder a
reasonable number of copies of any supplement to or amendment of such prospectus
that may be necessary so that, as thereafter delivered to the purchasers of such
Shares, such prospectus shall not include an untrue statement of a material fact
or omit to state a material fact  required to be stated  therein or

                                       59
<PAGE>

necessary  to make the  statements  therein not  misleading  in the light of the
circumstances then existing.

          7.4.6.  Promptly  notify  all  selling  Holders  of any stop  order or
similar  proceeding  initiated by state or federal regulatory bodies and use its
best efforts and take all necessary steps  expeditiously  to remove or terminate
such stop order or similar proceeding.

     7.5.  Description of Expenses.  All expenses  incurred by OCLI in complying
with any of the  foregoing  provisions  of this  Article  7,  including  without
limitation all federal and state  registration,  qualification  and filing fees,
printing  expenses,  any  premium  involved  in securing a policy or policies of
registration  insurance (but only if OCLI in its sole discretion shall choose to
secure such a policy or policies,  such policy or policies  hereinafter referred
to as "Registration Insurance"),  fees and disbursements of counsel for OCLI for
its services in facilitating the sale of Shares by the Holders in a registration
pursuant to Section 7.2, and  accountants'  fees and expenses (but excluding the
compensation  of OCLI's  regular  employees  which shall be paid in any event by
OCLI)  incident  to or  required  by any such  registration  are  herein  called
"Registration  Expenses".  All  underwriting  discounts and selling  commissions
applicable to the sale of Shares hereunder are herein called "Selling Expenses".
If OCLI is required by the  provisions of this Article 7 to use its best efforts
to effect the  registration  of any of the Shares under the Securities  Act, the
Registration  Expenses and Selling Expenses in connection with such registration
shall be borne as follows:

          (a)  All Registration Expenses shall be borne by OCLI.

          (b) All  Selling  Expenses  shall  be borne  pro  rata by the  Holders
including Shares in such registration.

     7.6.  Indemnification Underwriting Agreements.

          (a)  Registration  Statements.  In the event that OCLI registers under
the Securities Act any Shares held by a Holder:

               (i) OCLI will  indemnify and hold harmless such Holder,  and each
Person,  if any, who controls such Holder  within the meaning of the  Securities
Act, against any and all loss, liability or expense arising out of or based upon
any untrue  statement  or alleged  untrue  statement  of a material  fact in any
related registration statement,

                                       60

<PAGE>

prospectus,  offering  circular,  notification  or other  document  furnished or
authorized  by OCLI or any  omission or alleged  omission of any  material  fact
required to be stated  therein or  necessary to make the  statements  therein in
light of the  circumstances  under which they were made, not misleading,  unless
such statement, alleged statement or omission was made in reliance upon material
expressly  provided by such Holder for inclusion  therein or upon an omission or
failure by any such Holder to furnish any statement  with respect to such Holder
required to be included  therein.  In  connection  with any offering  under this
Article 7 which is to be  underwritten,  OCLI  further  agrees to enter  into an
underwriting agreement in usual and standard form respecting such offering.

               (ii)  OCLI's  obligations  under  Section  7.2 are subject to the
following  conditions:  (a) that each Holder  whose Shares are to be included in
any registration or qualification  referred to in this Article 7 shall agree, in
writing, prior to the filing of such registration or qualification, to indemnify
and hold  harmless  OCLI,  each Person,  if any,  who  controls  OCLI within the
meaning of the Securities Act and OCLI's officers and directors, against any and
all loss, liability or expense arising out of or based upon any untrue statement
or alleged  untrue  statement  of a material  fact in any  related  registration
statement,  prospectus, offering circular, notification or other document or any
omission or alleged  omission of any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not  misleading,  but only with reference to statements or
omissions made in reliance upon a statement in writing expressly furnished by or
on behalf of such Holder of inclusion  therein,  and (b) if such registration or
qualification  relates to an offering which is to be underwritten that each such
Holder  enters  into an  underwriting  agreement  in  usual  and  standard  form
respecting such offering.

               (iii) A party  required to indemnify  another  party  pursuant to
this 7.6(a) ("Indemnifying Party") shall not be liable for any settlement of any
action or claim  relating to such liability or expense  effected  without his or
its consent,  but if any  settlement is effected with his or its consent or if a
final  judgment  for  the  plaintiff  is  entered  in  any  such  action,   such
Indemnifying  Party will indemnify and hold harmless the indemnified  party from
and against any loss or liability by reason of any such settlement or judgment.

             INDEMNIFICATION AND STOCK ESCROW AGREEMENT


     INDEMNIFICATION  AND  STOCK  ESCROW  AGREEMENT  ("Agreement"),  dated as of
___________,  1996 by and among  Optical  Coating  Laboratory,  Inc., a Delaware
corporation   ("OCLI"),   Optical   Corporation  of  America,   a  Massachusetts
corporation ("OCA"), Kenneth D. Roberts (the "Shareholder Representative"),  and
First Interstate Bank, as escrow agent ("Escrow Agent").

     WHEREAS,  OCLI,  OCA  Acquisition  Corp.,  a  Delaware  corporation  and  a
wholly-owned subsidiary of OCLI, and OCA have entered into an Agreement and Plan
of Merger dated as of June 28, 1996 (the "Merger Agreement"),  contemplating the
acquisition by OCLI of all of the issued and outstanding shares of capital stock
of OCA (the "OCA Shares"); and

     WHEREAS,  the parties desire that certain shares of OCLI common stock to be
issued  pursuant to the Merger be  received,  held and disposed of by the Escrow
Agent subject to the terms and conditions herein expressed;

     WHEREAS,  the  execution  and  delivery  of this  Agreement  is a condition
precedent to the obligation of OCLI to consummate the transactions  contemplated
by the Merger Agreement;

     WHEREAS,  the provisions of this Agreement are  incorporated  in the Merger
Agreement and the purpose of this  separate  instrument  is the  convenience  of
OCLI, OCA and the  Shareholders and to facilitate the engagement of the services
of the Escrow Agent and the Shareholders Representative.

     NOW,  THEREFORE,  in  consideration  of these  premises  and other good and
valuable consideration, the parties hereto hereby agree as follows:

     Section 1.  Definitions.  Capitalized terms used herein which are
defined in the Merger Agreement but not defined herein shall have the same
meanings herein as therein.

     "Escrow  Termination  Date"  shall  mean the  first to occur of the date of
completion  of the  first  audit of OCA  covering  a  period  ending  after  the
Effective Date or the date which is the first anniversary of the Effective Date.

     Section 2.  Consent of Shareholders.  By virtue of the Shareholders'
approval of the Merger Agreement, the 

<PAGE>

Shareholders have, without any further act of any Shareholder, consented to:

          (i) the  establishment  of the escrow  account to ratify,  confirm and
secure OCA's  indemnification  obligations  under Section 4 of this Agreement in
the manner set forth herein,  (ii) the  appointment  of Kenneth D.  Roberts,  72
Windsor  Road,  Wellesley  Hills,  Massachusetts  02181-6134  (the  "Shareholder
Representative")  as their  representative for purposes of this Agreement and as
attorney-in-fact and as agent for and on behalf of each Shareholder,  (iii) that
the foregoing  appointment and designation shall be deemed to be coupled with an
interest  and  shall  survive  the  disability,  death  or  incompetency  of any
Shareholder,  (iv) the taking by the Shareholder  Representative  of any and all
actions and the making of any  decisions  required or  permitted  to be taken or
made by him under this Agreement and (v) all of the other terms,  conditions and
limitations of this Agreement.

     Section 3. Deposit of Escrow  Property.  OCLI hereby  deposits  with Escrow
Agent,  and Escrow Agent  hereby  acknowledges  receipt of, a stock  certificate
evidencing  ___________  (______) shares of OCLI's common stock, $0.01 par value
per share (the "Escrowed Shares").  Such certificate has been issued in the name
of Escrow Agent or its nominee.

     In case  any  distribution  (except  a cash  dividend  paid  out of  earned
surplus)  or stock  dividend  shall  be made on or in  respect  of the  Escrowed
Shares,  or any  property  shall  be  distributed  upon or with  respect  to the
Escrowed   Shares   pursuant   to   the    recapitalization,    liquidation   or
reclassification  of the  capital  structure  of OCLI or pursuant to the merger,
consolidation  or  reorganization  of OCLI,  the  money,  stock or  property  so
distributed  or paid shall be delivered  to and held by Escrow Agent  hereunder.
Such money, stock and property, together with the Escrowed Shares, are sometimes
referred to hereinafter as the "Escrow Property." Shareholders shall be entitled
to receive,  in proportion to their respective  number of Escrowed  Shares,  and
OCLI shall cause to be paid  directly to such  Shareholders  all cash  dividends
paid in respect of the Escrowed Shares out of the earned surplus of OCLI.

     While the Escrowed Shares are held by Escrow Agent,  Shareholders  shall be
entitled  to  direct  Escrow  Agent as to how to vote the  Escrowed  Shares,  in
proportion  to their  respective  number of  Escrowed  Shares,  with  respect to

                                       2
<PAGE>

matters  placed  before the  shareholders  of OCLI,  and Escrow Agent shall vote
accordingly.


     Section 4. Holding and Distribution of Escrow Property. OCLI (including the
Surviving  Corporation  after the Merger) upon their demand shall be indemnified
by the  Shareholders,  subject to Section 5 hereof,  for the full  amount of all
damages (as defined below) suffered by them as a direct or indirect result of:

          (i) the inaccuracy of any representation or warranty made by OCA in or
pursuant to the Merger Agreement,  in the form and to the extent so made, or the
omission to state in or  pursuant  to the Merger  Agreement  any  material  fact
relating to any such representation or warranty; and

          (ii) any failure by OCA to perform any  obligation  or comply with any
covenant or agreement specified in the Merger Agreement.

     For the purpose of this  Agreement,  the term "damages" shall be determined
and  computed  by  reference  to the  actual  economic  loss to OCLI  and/or the
Surviving  Corporation  (and not just by reference to any effect on the value of
the shares of the  Surviving  Corporation)  and shall be deemed to  include  all
losses,  liabilities,  expenses or costs incurred by the Surviving  Corporation,
and including reasonable  attorney's fees incurred in connection with objections
raised by the Shareholder Representative.

     OCLI shall give the Shareholder  Representative notice of any claim, action
or proceeding  by a third party which is reasonably  likely to result in a claim
for  indemnification  under this Section 4. OCLI shall have the right to defend,
contest,  protest and otherwise control the resolution of any such claim, action
or  proceeding  (unless OCLI decides in good faith not to contest such claim and
such  claim,  action or  proceeding  relates  to a matter  which,  if  adversely
determined,  would have no impact on the  Surviving  Corporation's  liability in
another  proceeding,  goodwill  or  reputation  or on the future  conduct by the
Surviving Corporation of its business or on its Tax or accounting positions,  in
which case the next  paragraph  shall  apply),  but shall  keep the  Shareholder
Representative  regularly and routinely advised of the status of any such claim,
action or proceeding.  The  Shareholder  Representative  shall have the right to
participate  in any such legal  proceeding,  subject to OCLI's  right of control
thereof,  at the  expense of the  Shareholder  

                                       3

<PAGE>

Representative  by counsel of the  Shareholder  Representative's  choice.  OCLI,
acting in good faith,  shall have the right in its sole discretion to settle any
such claim.

     If the claim,  action or proceeding is one which, if adversely  determined,
would  have no  impact on OCLI's or the  Surviving  Corporation's  liability  in
another  proceeding,  goodwill  or  reputation  or on the future  conduct by the
Surviving  Corporation  of its business or on its Tax or  accounting  positions,
then (i) the Shareholder Representative shall have the right, at his expense, to
defend, contest, protest and otherwise control the resolution thereof, but shall
keep OCLI  regularly  and  routinely  advised of the  status of any such  claim,
action or proceeding  and (ii) OCLI shall have the right to  participate  in any
such legal  proceeding,  subject to the  Shareholder  Representative's  right of
control thereof, at OCLI's expense and with counsel selected by OCLI.

     The Shareholder Representative shall be the person through whom all actions
on  behalf  of the  Shareholders  relating  to this  Agreement  shall be made or
directed  after  the  Closing  Date,  including  those  acts  as  are  required,
authorized or contemplated by this Agreement with respect to the settlement of a
claim or the defense thereof.  The other parties hereto are and will be entitled
to  rely  on  any  action  so  taken  or any  notice  given  by the  Shareholder
Representative  and  entitled  and  authorized  to  give  notices  only  to  the
Shareholder  Representative for any notice  contemplated by this Agreement to be
given any such  person.  The  Shareholder  Representative  shall be  entitled to
reasonable  compensation  and shall be reimbursed  for all  reasonable  expenses
incurred  by  him in  each  case  from  the  Escrow  Property.  The  Shareholder
Representative  shall have the right to sell Escrow  Property in order to obtain
funds to pay such  compensation  and expenses.  The  Shareholder  Representative
shall furnish reports as to the status of the escrow to the  Shareholders as and
when Escrowed  Shares are released  from the escrow or claims are paid.  OCLI or
the Surviving  Corporation shall not have any liability or responsibility to the
Shareholder Representative.

     The Shareholder  Representative shall receive and deliver notices on behalf
of  the   Shareholders   and  take  all  such  action  as  in  the   Shareholder
Representative's  discretion  may  be  necessary,   appropriate,   permitted  or
advisable to be taken under the terms of this  agreement in order to consent to,
pay, contest, arbitrate,  litigate or settle any claim or alleged claim asserted
hereunder.

                                       4

<PAGE>

     The Shareholder  Representative shall not be personally liable to the other
Shareholders for any action taken,  suffered or omitted by him in good faith and
reasonably  believed by him to be  authorized  or within the  discretion  of the
rights or powers conferred upon him by this Agreement.

     In  acting  as  representative   of  the   Shareholders,   the  Shareholder
Representative  may rely upon,  and shall be protected  in acting or  refraining
from  acting  upon,  an opinion of  counsel,  certificate  of  auditors or other
certificate,  statement,  instrument, opinion, report, notice, request, consent,
order, arbitrator's award, appraisal, bond or other paper or document reasonably
believed by him to be genuine and to have been signed or presented by the proper
party or parties.  The Shareholder  Representative  may consult with counsel and
any  advice  of such  counsel  shall  be full  and  complete  authorization  and
protection  in respect to any action taken or suffered or omitted by him in such
capacity  in good faith and in  accordance  with such  opinion of  counsel.  The
Shareholder  Representative may perform his duties as Shareholder Representative
either  directly or by or through his agents or  attorneys  and the  Shareholder
Representative  shall  not be  responsible  to the  other  Shareholders  for any
misconduct  or negligence  on the part of any agent or attorney  appointed  with
reasonable care by him hereunder.

     Upon  receiving  notice of the  death,  resignation  or  incapacity  of the
Shareholder  Representative,  the Shareholders  shall by majority vote (based on
their number of OCA Shares held immediately prior to the Closing Date) appoint a
successor  to fill the vacancy.  The  Shareholders  may by such a majority  vote
remove  the  Shareholder  Representative  with or  without  cause and  appoint a
successor,  provided  that  notice  thereof  is  given  by the  new  Shareholder
Representative to each of the other parties hereto.

     Section 5.  Limitation  of  Liability.  The right of OCLI and the Surviving
Corporation to be indemnified  pursuant to Section 4 shall be (a) limited to the
return to OCLI of the Escrow Property,  (b) shall not apply until the sum of the
damages  suffered by OCLI and the Surviving  Corporation  on a cumulative  basis
equals or exceeds  $250,000,  at which point OCLI and the Surviving  Corporation
shall be entitled to be indemnified for all damages,  not just amounts in excess
of $250,000, and (c) only for claims that are asserted by OCLI before the Escrow
Termination Date.

                                       5

<PAGE>

     Section 6. Escrow Account. It is intended that the assets held in escrow as
above provided shall facilitate OCLI's and the Surviving  Corporation's  ability
to recover amounts to which they are entitled as a result of misrepresentations,
breaches  of  warranties  and  breaches  of  covenants  contained  in the Merger
Agreement  and  to  satisfy  claims  of  OCLI  arising  as  a  result   thereof.
Accordingly,  and to the extent necessary to provide such protection to OCLI and
the Surviving Corporation,  property held in escrow hereunder shall be available
to satisfy claims of OCLI and the Surviving  Corporation under this Agreement to
the extent provided herein.  In the event the Escrow Property is insufficient to
pay the reasonable  expenses and compensation of the Shareholder  Representative
and all damages to OCLI and the  Surviving  Corporation,  including by virtue of
the expiration of the escrow period,  no Shareholder  shall be liable under this
Agreement  to pay any amount in  addition  to such  Shareholder's  proportionate
share of the Escrow  Property  expended  by the  Shareholder  Representative  or
claimed by OCLI prior to the Escrow Termination Date.

     Section 7.  Registration of Claims. In the event that OCLI or the Surviving
Corporation asserts any claim for  indemnification  against the Escrowed Shares,
it shall deliver to Escrow Agent and the  Shareholder  Representative  a written
notice thereof (the "Notice of Claim") setting forth (a) a demand for payment of
a  specified  amount  from the  Escrowed  Shares  or, if such  amount can not be
specified,  the  basis  upon  which the  amount  would be  determined  and (b) a
description of the asserted claim and the basis thereof,  and OCLI shall deliver
to the Shareholder  Representative  thereafter such other  information as may be
reasonably requested by the Shareholder  Representative to evaluate the asserted
claim.  It is understood and agreed among the parties hereto that OCLI's and the
Surviving  Corporation's right to assert claims for  indemnification  under this
Agreement is limited to those matters set forth in this Agreement,  although the
Escrow  Agent shall have no  obligation  to  determine  or verify  whether  such
condition has been met.

     Section 8.  Payment of Amounts  from Escrow  Property  Upon Demand  Without
Objection. If OCLI delivers to the Shareholder Representative and Escrow Agent a
Notice of Claim pursuant to Section 7 hereof and if no written objection to such
demand  is   received   by  Escrow   Agent  and  OCLI,   from  the   Shareholder
Representative, within 30 days following the delivery of such Notice of Claim to
Escrow Agent and the Shareholder Representative, then Escrow Agent shall pay the
claim out of the Escrow  Property by forthwith


                                       6

<PAGE>

endorsing and  delivering  to OCLI the  certificates  representing  the Escrowed
Shares.  OCLI shall be entitled to retain that number of Escrowed  Shares which,
when  multiplied  by the Per Share  Value (as  defined  below),  shall equal the
amount of the claim as provided  in Section 4 hereof;  provided,  however,  that
Notices of Claim must be delivered  before the Escrow  Termination Date and OCLI
may not retain  more than the  Escrowed  Shares.  OCLI shall  return one or more
certificates  for the  excess  Escrowed  Shares  to Escrow  Agent for  continued
holding  hereunder.  To the extent the value (calculated on the basis of the Per
Share  Value,  regardless  of actual  market  value at the time) of the Escrowed
Shares retained by OCLI is less than the amount of the claim, Escrow Agent shall
also transfer to OCLI other Escrow Property, if any, in addition to the Escrowed
Shares.

     The Per Share Value shall be the reported  closing  price of OCLI's  Common
Stock on the Nasdaq National Market System on the date of this Agreement.

     Section  9.  Payment  of  Amounts  from  Escrow  Property  After  Notice of
Objection. If OCLI delivers to the Shareholder Representative and Escrow Agent a
Notice  of  Claim  pursuant  to  Section  7  hereof,   and  if  the  Shareholder
Representative  shall give  written  objection  thereto to Escrow Agent and OCLI
prior to the  expiration  of the 30-day  period  specified  in Section 8, Escrow
Agent shall make no payment in respect of the demand set forth in such Notice of
Claim until it shall have received one of the following:

          (a)  written instructions signed on behalf of both OCLI and the
Shareholder Representative; or

          (b) a final order of a court  having  jurisdiction  over the  asserted
claim, after expiration of any applicable appeal period.

     Upon receipt of any such instructions or order, Escrow Agent shall pay such
amount from the Escrow Property to OCLI as may be directed by such  instructions
or order;  provided,  however  that (i) the  limitations  set forth in Section 8
hereof on the number of Escrowed  Shares  retainable by OCLI shall also apply to
claims paid under this Section 9, and (ii) all Escrowed Shares delivered to OCLI
shall be valued on the basis of the Per Share  Value,  regardless  of the actual
market  price of OCLI's  Common  Stock on the date such shares are  delivered to
OCLI. If the final order of a court having jurisdiction over the asserted claim,
after  expiration  of any  applicable  appeal  period,  upholds the  Shareholder
Representative's  objection to the Escrow Agent,

                                       7

<PAGE>

OCLI  shall  reimburse  the  Escrow  Agent and  Shareholder  Representative  for
reasonable  attorneys' fees and expenses paid from the Escrow Property to pursue
the objection.

     Section  10.  Payment of Escrow  Property  to  Shareholders.  On the Escrow
Termination  Date,  Escrow  Agent  shall  deliver  to OCLI  and the  Shareholder
Representative  a  statement  of the  remaining  balance,  if any, of the Escrow
Property  (calculated  on the basis of the Per Share  Value,  regardless  of the
actual market price of OCLI's  Common Stock at that time),  and the total amount
of all  claims  registered  pursuant  to  Section 7 hereof  and not  theretofore
resolved and paid (the excess,  if any, of such remaining balance over the total
amount of such claims shall be referred to as the "Final Escrow Balance").  OCLI
and the Shareholder Representative shall review the accuracy of the Final Escrow
Balance and notify Escrow Agent within 30 days of the foregoing statement of any
asserted discrepancy.  Upon the expiration of the 30-day period after receipt by
OCLI and the Shareholder  Representative of such statement,  and if Escrow Agent
has  not  been  notified  of  any   discrepancy  by  OCLI  or  the   Shareholder
Representative  within the 30-day period  specified in the  preceding  sentence,
Escrow Agent shall deliver to each Shareholder Escrow Property representing such
Shareholder's  share of the Final Escrow  Balance,  free and clear of the escrow
created  by this  Agreement.  After the last  registered  claim  shall have been
resolved  pursuant  to Section 8 and  Section 9 hereof,  as the case may be, and
paid, the remaining  balance,  if any, of the Escrow Property shall be delivered
by Escrow  Agent to the  Shareholders,  free and clear of the escrow  created by
this Agreement;  provided,  however, that upon the disposition of any such claim
prior to the  disposition  of all such  claims  Escrow  Agent  shall  deliver to
Shareholders  the  Escrow  Property  in  excess of the  amount of the  remaining
aggregate  claims  as  determined   above.  All  payments  by  Escrow  Agent  to
Shareholders  pursuant  to this  Agreement  shall be made in  proportion  to the
Shareholders' respective interests in the Escrowed Shares.

     Section 11.  Responsibility of Escrow Agent.  Escrow Agent may act upon any
instrument  or other  writing  believed by it in good faith to be genuine and to
have been signed or  presented  by the proper  person and shall not be liable to
any party hereto in connection  with the  performance  of its duties  hereunder,
except for its own negligence or willful misconduct. Escrow Agent's duties shall
be determined  only with reference to this Escrow  Agreement and applicable laws
and  Escrow  Agent  is  not  charged  with   knowledge  of,  or  any  duties  or
responsibilities  in connection  with,  any other

                                       8

<PAGE>

document  or  agreement.  If in  doubt  as to its  duties  and  responsibilities
hereunder,  Escrow  Agent may  consult  with  counsel of its choice and shall be
protected  in any  action  taken or  omitted  in  connection  with the advice or
opinion of such counsel.

     If any party to this  Agreement  disagrees on anything  connected with this
escrow (1) Escrow Agent will not have to settle the matter, (2) Escrow Agent may
wait for a settlement by  appropriate  legal  proceedings  or other means it may
require,  and in such event it will not be liable for interest or damage, (3) if
Escrow Agent intervenes in or is made a party to any legal proceedings,  it will
be entitled to such reasonable  compensation for services,  costs and attorney's
fees as the court may award and (4) Escrow  Agent is entitled to hold  documents
and assets  deposited in this escrow pending  settlement of the  disagreement by
any of the above means.

     Escrow Agent is to act as a depositary agent only and is hereby relieved of
any liability in connection with any  representations  made by the other parties
hereto or any of their  agents.  Escrow Agent shall not be  responsible  for and
shall not be under a duty to examine any other agreement.

     Section 12.  Indemnification  and Fees of Escrow Agent. In consideration of
its acceptance of the appointment as Escrow Agent, OCLI shall indemnify and hold
Escrow Agent  harmless as to any  liability  incurred by it to any other person,
firm or corporation by reason of its having accepted the same or in carrying out
any of the  terms  hereof,  and to  reimburse  the  Escrow  Agent  for  all  its
out-of-pocket expenses,  including,  among other things, reasonable counsel fees
and court costs,  incurred by reason of its position  hereunder or actions taken
pursuant hereto,  except in the event of the negligence or willful misconduct of
Escrow  Agent.  The fees and charges set forth below for the  services of Escrow
Agent will be considered  compensation for Escrow Agent's  ordinary  services as
contemplated  by this  Agreement.  In the event the conditions of the escrow are
not promptly  fulfilled or Escrow Agent  renders any service not provided for in
this  Agreement or there is any assignment of any interest in the subject matter
of this escrow or modification  of any interest or if any controversy  arises in
connection  with  it,  Escrow  Agent  will be  reasonably  compensated  for such
extraordinary  services,  and  will  be  reimbursed  for all  reasonable  costs,
attorney's fees and expenses occasioned thereby, which compensation, costs, fees
and expenses shall be paid by OCLI.

                                       9

<PAGE>

     Escrow  Agent's  initial  acceptance  fee is $_________  and Escrow Agent's
annual fee hereunder is $_________,  which fees are  nonrefundable  and shall be
paid in advance by OCLI.

     Section 13.  Resignation  of Escrow  Agent.  Escrow Agent may resign and be
discharged from its duties hereunder at any time by giving not less than 60 days
prior  written  notice  of  such   resignation  to  OCLI  and  the   Shareholder
Representative,  which notice shall specify the date when such resignation shall
take effect.  Upon such notice,  OCLI and the Shareholder  Representative  shall
appoint a successor escrow agent. If OCLI and the Shareholder Representative are
unable to agree upon a successor  escrow agent within 30 days after such notice,
Escrow  Agent  may  apply  to  a  court  of  competent   jurisdiction  for  such
appointment.  Escrow Agent shall continue to serve until its successor  delivers
to  OCLI  and the  Shareholder  Representative  a duly  executed  instrument  of
acceptance of the terms and conditions of this Agreement and receives the Escrow
Property.

     Section 14. Investments.  Escrow Agent shall invest the cash portion of the
Escrow     Property,     if    any,    in    money     market     accounts    at
____________________________________.  Income from any such investment  shall be
held by Escrow Agent, shall be reinvested in accordance with this Section 14 and
shall be considered part of the Escrow Property.

     Section 15. Security  Interest.  To secure the obligations that may be owed
it hereunder,  OCLI shall have a security  interest in the Escrow Property,  and
for purposes of protection of an enforceable  security  interest,  possession of
the Escrow Property by the Escrow Agent shall be deemed possession by OCLI.

     Section 16. Notices and Communications.  Any notice or other communications
hereunder  shall be deemed to have been duly  delivered  if delivered by hand or
overnight   courier   service  to  the  party  to  whom  such  notice  or  other

                               AFFILIATE AGREEMENT



                                                                   June 28, 1996



Optical Corporation of America
7421 Orangewood Avenue
Garden Grove, California 92641

Optical Coating Laboratory, Inc.
2789 Northpoint Parkway
Santa Rosa, California  95407-7397

Ladies and Gentlemen:

     The undersigned  Shareholder (the  "Shareholder") of Optical Corporation of
America, a Massachusetts  corporation ("OCA"),  understands that OCA has entered
into an Agreement and Plan of Merger (the "Merger  Agreement")  dated as of June
28,  1996  among  Optical  Coating  Laboratory,  Inc.,  a  Delaware  corporation
("OCLI"), OCA Acquisition Corporation, a Delaware corporation and a wholly-owned
subsidiary of OCLI ("Acquisition"), and OCA.

     Pursuant to the Merger  Agreement,  Acquisition  will merge (the  "Merger")
with and into OCA, following which OCA will become a wholly-owned  subsidiary of
OCLI.  The Merger  Agreement  provides that, on the Effective Date of the Merger
(as defined in the Merger  Agreement),  all of the outstanding shares of capital
stock of OCA will be  converted  into shares of common  stock of OCLI (the "OCLI
Common Stock") in accordance with the applicable exchange ratio specified in the
Merger Agreement.

     The  Shareholder  has  been  advised  that  as  of  the  date  hereof,  the
Shareholder  may be deemed to be an "affiliate" of OCA, as the term  "affiliate"
is (i) defined for purposes of paragraphs (c) and (d) of Rule 145 promulgated by
the Securities and Exchange  Commission (the "Commission")  under the Securities
Act of 1933,  as  amended  (the  "Act"),  and (ii) used in and for  purposes  of
Accounting Series Releases 130 and 135, as amended, of the Commission.

                                       1
<PAGE>

     The  Shareholder  understands  that  the  representations,  warranties  and
covenants  set forth  herein will be relied upon by OCLI,  Acquisition,  OCA and
other shareholders of OCA, and their respective counsel and accounting firms.

     The  Shareholder  represents,  warrants  and  agrees  with  OCLI and OCA as
follows:

     1. The  Shareholder  is the  beneficial  owner of the shares of OCA capital
stock and  options to  purchase  OCA capital  stock  indicated  on the last page
hereof  (the "OCA  Securities"),  which at the date  hereof  and at all times up
until the Effective Date will be free and clear of any liens,  claims,  options,
charges  or other  encumbrances  not  described  on such  page.  Except  for OCA
Securities,  the  Shareholder  does not  beneficially  own any shares of capital
stock  of  OCA or any  other  equity  securities  of OCA or any  other  options,
warrants  or  other  rights  to  acquire  any  equity  securities  of  OCA.  The
Shareholder  has full power and authority to make,  enter into and carry out the
terms of this Agreement.

     2. The  Shareholder  has been  advised  that the issuance of shares of OCLI
Common  Stock to the  Shareholder  (the "OCLI  Shares") in  connection  with the
Merger has been or will be  registered  with the  Commission  under the Act on a
registration  statement  on Form S-4.  However,  the  Shareholder  has also been
advised that since at the time the Merger is to be  submitted  for a vote of the
shareholders  of OCA the Shareholder may be deemed to be an affiliate of OCA and
the  distribution  by the  Shareholder  of any OCLI  Shares  will not have  been
registered  under the Act, the Shareholder  may not sell,  transfer or otherwise
dispose of the OCLI Shares unless (i) such sale,  transfer or other  disposition
has been registered under the Act, (ii) such sale, transfer or other disposition
is made in compliance with Rule 145 promulgated by the Commission under the Act,
or (iii) such sale,  transfer  or other  disposition  is  otherwise  exempt from
registration under the Act.

     3. The Shareholder  shall not make any sale,  transfer or other disposition
of the  OCLI  Shares  in  violation  of the  Act or the  rules  and  regulations
promulgated thereunder.

     4.  Except  as  provided  for  in the  Merger  Agreement,  the  Shareholder
understands  that OCLI is under no obligation to register the sale,  transfer or
other  disposition  of the  OCLI  Shares,  or  OCLI  Common  Stock  held  on the
Shareholder's  behalf,  under the Act or to take any other  action  necessary

                                       2

<PAGE>

in order to make compliance with an exemption from such registration available.

     5.  Notwithstanding any other provision hereof to the contrary,  during the
period  commencing  on the date  hereof  and  ending at such  time as  financial
results  covering at least  thirty days of combined  operations  of OCA and OCLI
have been  published  by OCLI in the form of a  quarterly  earnings  report,  an
effective  registration  statement  filed with the  Commission,  a report to the
Commission on Form 10-K, 10-Q or 8-K, or any other public filing or announcement
which  includes  the  combined  results  of  operations  of OCLI  and  OCA,  the
Shareholder will not sell,  transfer or otherwise  dispose of, or offer or agree
to sell,  transfer or otherwise  dispose of, or in any other way reduce the risk
of the  Shareholder's  ownership of or investment  in, any OCA  Securities,  any
shares  of OCA  common  stock  or  other  equity  securities  of OCA  which  the
Shareholder  purchases or acquires  after the execution of this  Agreement,  the
OCLI  Shares or any  securities  which may be paid as a  dividend  or  otherwise
distributed  thereon or with respect  thereto or issued or delivered in exchange
or substitution therefor (all such shares and other securities being referred to
herein, collectively, as "Restricted Securities"), or any option, right or other
interest  with  respect  to any  Restricted  Securities.  Without  limiting  the
foregoing,  the Shareholder  acknowledges  that such  restriction  prohibits the
acquisition of a "put" option or other hedging  instrument  with respect to OCLI
common stock.

     6. Stock transfer  instructions will be given to OCLI's transfer agent with
respect to the OCLI Shares and there will be placed on the  certificates for the
OCLI Shares, or any substitutions therefor, a legend stating in substance:

     "The shares represented by this certificate were issued in a transaction to
     which Rule 145  promulgated  under the Securities Act of 1933 applies.  The
     shares   represented  by  this  certificate  may  only  be  transferred  in
     accordance with the terms of an agreement dated as of June 28, 1996 between
     the registered holder hereof and OCLI, a copy of which agreement is on file
     at the principal offices of OCLI."

     7.  Unless the  transfer  by the  Shareholder  of the OCLI  Shares has been
registered  under the Act, or a sale is made in  compliance  with Rule 145, OCLI
reserves the right to put 

                                       3

<PAGE>

a legend on the certificates issued to any transferee of the Shareholder stating
in substance:

     "The shares  represented by this certificate have not been registered under
     the  Securities  Act of 1933 and were  acquired  from a person who received
     such  shares  in a  transaction  to which  Rule 145  promulgated  under the
     Securities  Act of 1933  applies.  The shares  may not be sold,  pledged or
     otherwise  transferred  except in  accordance  with an  exemption  from the
     registration requirements of the Securities Act of 1933."

     8. The  legends set forth in  paragraphs  6 and 7 above shall be removed by
delivery of substitute  certificates  without the  applicable  legend if, in the
opinion of counsel to OCLI,  (a) such legend is not required for purposes of the
Act or (b)  the  sale  or  other  disposition  of the  shares  evidenced  by the
certificate is permitted by the provisions of Rule 145(d)).  In any event,  such
legend may be removed  upon request of the  Shareholder  no later than two years
after the Merger is  consummated,  unless the Shareholder is then an "affiliate"
of OCLI within the meaning of Rule 145(d).

     9. At every meeting of the  shareholders  of OCA called with respect to any
of the  following,  and at every  adjournment  thereof,  and on every  action or
approval by written  consent of the  shareholders  of OCA with respect to any of
the following,  the Shareholder  shall vote all his OCA Shares:  (i) in favor of
approval  of the Merger  Agreement  and the  Merger  and any  matter  that could
reasonably be expected to facilitate  the Merger;  and (ii) against  approval of
any proposal made in  opposition  to or  competition  with  consummation  of the
Merger (the foregoing is hereinafter referred to as an "Opposing Proposal").

     10.  Except  as  required  by  law,  including  actions  which  Shareholder
determines  after  consultation  with legal  counsel  are  required  pursuant to
Shareholder's  fiduciary duties under applicable law,  Shareholder will not, and
will not permit any entity under  Shareholder's  control to: (i) solicit proxies
or become a  "participant"  in a  "solicitation"  (as such terms are  defined in
Regulation  14A under the Exchange  Act) with  respect to an Opposing  Proposal;
(ii) initiate a shareholders' vote or action by consent of OCA shareholders with
respect to an Opposing  Proposal;  or (ii) become a member of a "group" (as such
term is used in Section  13(d) of the  Exchange  Act) with respect

                                       4

<PAGE>

to any voting securities of OCA, in connection with an Opposing Proposal.

     11. The Shareholder  hereby covenants and agrees to execute and deliver any
additional  documents  reasonably  necessary or  appropriate,  in the opinion of
OCLI, to carry out the intent of this Agreement.

     12.  Miscellaneous.

          12.1  If  any  term,  provisions,  covenant  or  restriction  of  this
Agreement is held by a court of competent  jurisdiction  to be invalid,  void or
unenforceable,  all other terms, provisions,  covenants and restrictions of this
Agreement shall nevertheless remain in full force and effect and shall in no way
be affected, impaired or invalidated.

          12.2 This Agreement and all of the provisions  hereof shall be binding
upon and  inure to the  benefit  of the  parties  hereto  and  their  respective
successors and permitted assigns, but, except as otherwise specifically provided
herein,  neither this Agreement nor any of the rights,  interests or obligations
of the parties hereto may be assigned by either of the parties without the prior
written consent of the other.

          12.3  This  Agreement  may  not  be  modified,   amended,  altered  or
supplemented  except upon the  execution  and  delivery  of a written  agreement
executed by the parties hereto.

          12.4 The  parties  hereto  acknowledge  that OCLI will be  irreparably
harmed and that there will be no adequate  remedy at law for a violation  of any
of the covenants or agreements of Shareholder set forth herein. Therefore, it is
agreed  that,  in addition to any other  remedies  that may be available to OCLI
upon any such violation, OCLI shall have the right to enforce such covenants and
agreements  by  specific  performance,  injunctive  relief or by any other means
available to OCLI at law or in equity.

          12.5 All notices, requests,  claims,, demands and other communications
hereunder  shall be in writing and sufficient if delivered in person,  by cable,
telegram  or telex,  or sent by mail  (registered  or  certified  mail,  postage
prepaid,  return  receipt  requested)  or  overnight  courier  (prepaid)  to the
respective parties as follows:

SECTION 3.2(A)

     The Business of OCA as it is now being conducted is described as follows:

GENERAL

     OCA  develops,   manufactures  and  markets  optical  and   electro-optical
products,  components  and subsystems  for a wide range of  applications  in the
medical,  telecommunication,   industrial,  scientific,  aerospace  and  defense
industries.  OCA focuses on four categories of product and related services: (1)
Optical  Filters,   (2)  Electro-Optical   Sensors  and  Cameras,   (3)  Optical
Correlators  and (4) Fiber  Optics  Communications  Devices.  OCA also  enjoys a
significant  business in optical  components  and  subsystems for commercial and
government markets.

PRODUCTS AND SERVICES

(1)  OPTICAL FILTERS

     OCA designs,  manufactures  and markets optical  filters which  incorporate
proprietary  technology for  multi-layer  thin film coatings.  Optical thin film
coatings  control  and  enhance  light  energy  by  altering  the  transmission,
reflection  and  absorption  of the  various  wavelengths  of light to achieve a
desired  optical  effect.  OCA has  developed a thin-film  coating  process call
MicroPlasma' (patent pending) which permits OCA a distinct competitive advantage
in providing high quality  optical  filters to customers in various  industries.
Optical filters are used as components in instruments  and systems  manufactured
by  original  equipment   manufacturers   (OEMs),   principally  to  bio-medical
instrument manufacturers.  OCA has steadily

                                       3

<PAGE>

increased its production  capacity in this area and has achieved a high level of
automation.  OCA  expects  that an  increasing  share  of the  filters  which it
manufactures  will be used in the  production  of its Fiber Optic  Communication
Devices.

     In  addition,  OCA  produces a variety of filters  and  coatings  utilizing
standard or traditional evaporation technologies, including "soft" coatings. OCA
also  produces  epoxy dye plates that  eliminate the need for  expensive,  often
difficult to obtain,  filter color glass.  The unique dye process used by OCA is
applicable to traditional coatings,  as well as MicroPlasma coatings,  and often
is a more cost competitive process for filter manufacturing.

     OCA's line of optical filters runs from the ultraviolet through the visible
and into the  infrared  spectrum of light.  OCA also makes  filters  which block
certain wavelengths of light for eye-safe laser protection devices,  and passive
intrusion filters which detect heat from bodies  approaching a field of view and
will  activate a switching  mechanism.  These  products are often termed  motion
detection  devices  but in fact  rely  on heat  transmitted  by a  source  at an
infrared wavelength.

     Optical filters are produced for a highly competitive market.

(2)  ELECTRO-OPTICAL SENSORS AND CAMERAS

     OCA is recognized by its  customers as a premiere  supplier of  lightweight
electro-optical  sensor systems for airborne and spaceborne  applications.  This
recognition  stems  from  OCA's  participation  in  the  Brilliant  Pebbles  and
Clementine Programs in the late 1980s and early 1990s sponsored by the Strategic
Defense  Initiative/Ballistic Missile Division, which allowed OCA to enhance its
already  strong  opto-mechanical  background  with  state-of-the-art,   in-house
electronics design and fabrication capabilities.

     OCA's color video cameras set a new standard for  performance and low mass.
OCA plans to encourage use of this product and  technology in both space related
and commercial applications.

     OCA's new Wide Field of View Star Tracker  Camera has been selected for use
on both the Mars  Surveyor  '98 Orbiter and Lander  Missions.  In this  version,
image  processing  to  determine  spacecraft  attitude  is  accomplished  by the
spacecraft computer, using Stellar Compass software licensed


                                       4

<PAGE>

by OCA to the user.  For  applications  where the user prefers a  self-contained
Star Tracker to compute the spacecraft's attitude directly,  OCA has teamed with
Southwest  Research  Institute  to  supply  a  state-of-the-art  RAD-6000  based
computer  module.  OCA's  product  offers the most cost  effective  solution for
attitude determination in the developing field of small, low-cost spacecraft and
has been selected as the "baseline" for a number of new programs.

     OCA's experience with lightweight  sensors  positions it to capitalize upon
the shift from small numbers of large,  costly spacecraft to much larger numbers
of small,  relatively  inexpensive spacecraft for both government and commercial
applications. OCA anticipates that a substantial fraction of its future business
can be derived from this technology base.

(3)  OPTICAL CORRELATORS

     OCA has an  established  reputation  in the  field of  Optical  Processing.
Beginning in 1985, OCA became one of the original system hardware  innovators in
this field,  transforming  theoretical  analysis and  scientific  research  into
development efforts for field deployable hardware which could be used for target
recognition  and target  tracking in missile  systems.  The  fundamentals of the
technology  employ the inherent strength of optics to process an entire scene of
data  instantaneously  (at the speed of light).  Analytical  speed combined with
relatively low power and packaging requirements, yields an attractive technology
for programs which incorporate optical processing.  OCA will continue to support
government applications using optical processing for guidance and navigation and
radar imagery analysis;  in particular,  because optical processing provides the
foundation of its commercial correlator line.

     The potential for commercial  applications is found in factory  automation,
security,  medical  imagery  and  remote  sensing  imagery.  OCA  is  developing
solutions for each of these  applications.  For example,  OCA will  introduce in
1996 a commercial optical processor.  The Flash 256 Optical Fourier Processor is
an entirely  new product for the image  processing  industry,  with  significant
competitive implications.

(4)  FIBER OPTIC COMMUNICATIONS DEVICES

     OCA has recently  introduced  a new line of optical  devices for use in the
fiber optic communications  market. OCA manufactures four devices  incorporating
filters  produced

                                       5
<PAGE>

by OCA using its proprietary  MicroPlasma'  (patent  pending)  coating  process.
These devices are (a) a Channel  Add/Drop  Filter,  (b) a Tunable Bandpass Fiber
Optic Filter, (c) a 4 Channel Dense Wavelength  Division  Multiplexer (DWDM) and
(d) an 8 Channel Dense Wavelength  Division  Multiplexer  (DWDM).  These devices
generally  operate  in the 1530 to 1560  nanometer  (nm)  range  and are  unique
because of their ability to operate in a passive mode.

     In addition to their narrow bandwidths, their low cross-talk (the result of
OCA's  ability to produce 3 cavity and 5 cavity filter  designs),  low insertion
loss and durability,  these devices also demonstrate  high wavelength  stability
and minimal  temperature  shift (less than .001 nm/DC temperature  shift).  This
minimal shift is the result of OCA's MicroPlasma' process.

     OCA  believes its devices are enabling  technology  which will  accommodate
significantly  increased data transmission  over the existing  installed base of
fiber optic cable. While other DWDM devices exist which might compete with those
manufactured by OCA, to date OCA believes its devices are the most advanced, and
filter  based  devices  appear to have a technical  advantage  over  alternative
technologies.

OPTICAL COMPONENTS AND SUB-SYSTEMS

     OCA plays a significant  role in the design and manufacture of leading edge
optical  products.  OCA has been  selected  repeatedly  by  leading  commercial,
scientific and defense  organizations to work cooperatively under formal teaming
agreements and strategic  alliances to develop  innovative  solutions to optical
design,  packaging  and  manufacturing  problems  for a wide  range  of  product
applications. The importance of the technologies developed during these projects
continues  to grow  with the  emergence  of the  small  satellite  industry  for
commercial  applications  such as  Earthwatch.  OCA is currently  developing the
telescope for the Earthwatch  remote sensor which is expected to provide 3 meter
resolution photographs of the earth for commercial users.

     OCA has also been a  supplier  to the  semi-conductor  equipment  industry.
Contracts  from KLA, SVG and others total over two million  dollars on an annual
basis.

     OCA's  development of advanced infrared search and track (IRST) and missile
launch detection  systems in cooperation  with  Westinghouse and Lockheed Martin
addresses a growing

                                       6

market for the protection and  improvement of our nation's  existing air defense
capabilities.

RESEARCH AND DEVELOPMENT

     OCA focuses its research and  development  activities on the development of
new proprietary products, enhancements to existing products, and enhancements of
core  technologies.  OCA funds these  activities from both internal  sources and
external contracts.

MANUFACTURING

     OCA's approach is to identify and perform  internally those functions which
enable it to maintain control over critical  portions of the production  process
and  which  add  value to its  products.  At the  same  time,  OCA's  purchasing
departments  make every effort to insure that qualified  suppliers are available
for functions which are better or more  economically  performed by others.  Both
OCA's  California  and  Massachusetts  operations  have  complete,  stand  alone
capabilities  appropriate  to the  support of the  varying  requirements  of its
Business and customers. Engineering, manufacturing Sales and Marketing personnel
are available at both locations.

     In  California,  OCA  designs,  manufactures,  coats,  assembles  and tests
electro-optical  subsystems and complex electro-optical  assemblies for customer
use in infrared, Visible and Ultraviolet systems. OCA's fabrication capabilities
are sophisticated and include Single Point Diamond Turning,  electroless  nickel
plating and Beryllium Hot Isostatic  Pressing,  and allow OCA to produce compact
and lightweight subsystems without the degree of subcontracting required by most
of its competitors.

     In  Massachusetts,  OCA is a leading provider of thin film products for OEM
customers.  OCA's  state-of-the-art  coatings,  combined  with  its  proprietary
automation  processes,  assure a solid market presence.  Additional  capacity is
being added to meet the  forecasted  demand for OCA's new  products in the fiber
optic communications marketplace.  The enabling technology is the optical filter
and OCA  produces  filters  routinely  that equate to over $10 million in annual
sales. The packaging capability to support the DWDM product is operational.

SALES, MARKETING AND CUSTOMER SUPPORT

     The major products of OCA, as well as the Commercial and Government Optics,
are all supported by a direct  technical sales force located at OCA's California
and  Massachusetts   operations.   On  an  international  basis,  OCA  maintains
representatives throughout Europe, Asia and South America.

PATENTS AND INTELLECTUAL PROPERTY

     OCA believes the success of its  business  depends more upon the  technical
competence and  creativity of its employees than on its patents,  trademarks and
copyrights.  Nevertheless,  OCA seeks patents,  when appropriate,  on inventions
concerning  new  products  and  improvements  as part of its  ongoing  research,
development  and  manufacturing  activities.  OCA also relies upon trade  secret
protection  for its  confidential  and  proprietary  information.  OCA routinely
enters into confidentiality agreements with other entities and individuals.

     Included  among  these  assets  were  certain  contracts  for  which  final
settlement  of  P-E's  price  redeterminable  costs  has  yet  to  occur.  Audit
activities  conducted by the Defense  Contract Audit Agency  ("DCAA") for P- E's
fiscal years 1987-1989 and fiscal year 1990 through March 22, 1990 reveal issues
related to P-E's allocation of certain costs which have been questioned by DCAA.

SECTION 3.2(S)

     EXCEPTIONS:

      First Sentence -

     a) P-E has commenced an action to require OCA to repurchase the P-E Shares.
See Section3.2(q) of this Disclosure Schedule, above.

     b) The  Spar  Contract  Matter.  OCA is a party  to a  contract  with  Spar
Aerospace Limited of Brampton,  Ontario,  Canada ("Spar") which provides for the
export to Canada for  inclusion in the  International  Space  Station of certain
equipment to be  manufactured  by OCA. OCA has identified the possibility of its
non-compliance  with certain U.S.  Government Export Control Regulations and has
initiated and engaged in voluntary  discussions with the Office of Defense Trade
Controls,  Bureau of  Political  Military  Affairs,  U. S.  Department  of State
regarding  future  commitments to minimize the likelihood of improper  export by
OCA. Until such  discussions are concluded,  OCA has  voluntarily  suspended any
scheduled delivery to Spar which could be subject to such Regulations.

     OCA's  billings on the Spar Contract are based on milestones to be achieved
by OCA.  If  achievement  of these  milestones  is  delayed  while OCA  awaits a
response  from the  Department  of State,  there is no  relief to OCA's  current
inventories. OCA expects this matter to be resolved within the current milestone
billing schedule.

period  from  the  date of  this  Agreement  through  September  30,  1996 in an
aggregate amount of $1,576,000.

SUBSECTION  3.3(K), COMPLIANCE WITH LAWS

     In  1988,  Optical  Coating  Laboratory,  Inc.  ("OCLI"  or the  "Company")
discovered ground water contamination at its principal facilities in Santa Rosa.
The Company conducted

                                       3
<PAGE>

extensive  investigations  to determine the lateral and vertical  extent and the
environmental  impact of the  contamination.  During  1990,  OCLI  substantially
completed its investigation and study and formulated a plan of remediation.  The
total cost of the  investigation  was  approximately  $5 million  which has been
charged to operations in prior periods.

     Based upon extensive tests conducted to date, it has not been  demonstrated
that  contaminant  levels  pose  a  current  public  health  hazard.   OCLI  has
established  a  program  for  reducing   contaminant   concentration  levels  to
acceptable  federal and state levels with the  assistance  of its  environmental
consultants and under the regulatory  guidance of the California  Regional Water
Quality Control Board.  OCLI is continuing to evaluate the  effectiveness of its
monitoring,  extraction  and  remediation  systems.  In  addition,  the  Company
anticipates  drilling  additional  monitoring and extraction wells in connection
with its final remediation plan.

     Based  upon the  extensive  tests  conducted  and  advice of  environmental
consultants,  OCLI  believes  the  accruals  it has  previously  established  to
complete  the  remediation  plan are  sufficient  and that  the  annual  cost of
maintaining compliance with environmental  standards related to the above matter
will not have a material  adverse  effect on the Company's  business,  financial
position or prospects.

                              EMPLOYMENT AGREEMENT

    AGREEMENT  made as of June __, 1996 by and between  Optical  Corporation  of
America, having its principal place of business at 170 Locke Drive, Marlborough,
MA 01752(the "Company"), and  _______________________________  (the "Employee"),
whose address is set forth on the execution page hereof.

    1. Term of Employment. The Company hereby agrees to employ the Employee, and
the Employee hereby agrees to be employed by the Company, commencing on the date
hereof,  for a period of two (2)  years,  subject  to the  terms and  provisions
hereof. As used herein, the phrase "employment term" refers to the entire period
of employment of the Employee by the Company  hereunder,  whether for the period
provided above, a lesser period if terminated  earlier as hereinafter  provided,
or a greater period if extended by mutual  written  agreement of the Company and
the Employee.

    2. Duties of Employee. The Employee shall initially be employed with the job
description and title, if any,  specified on the execution page hereof.  In such
employment, his duties and authority shall be as determined from time to time by
the Company.  The Employee will devote his  knowledge,  skill,  working time and
energy  to the  performance  of his  duties  in an  efficient,  trustworthy  and
businesslike  manner,  and will not engage in any other business,  profession or
occupation for compensation or otherwise which would conflict with the rendition
of such  services,  either  directly or  indirectly,  without the prior  written
consent of the Company. The Employee shall serve in such capacities and shall do
and perform all such services,  acts or things  necessary and appropriate in the
course  of his  employment  as  reasonably  required  from  time  to time by the
Company.  The Employee shall not directly or indirectly render any services of a
business,  commercial or  professional  nature during the employment term to any
other person or organization,  whether for compensation or otherwise, that would
conflict with the rendition of services under this agreement,  without the prior
written consent of the Company.

    3.   Compensation of Employee.  For the period of his employment term,
the Employee shall be compensated for his services as follows:

         (a)  the  Employee  shall  receive  compensation  as  specified  on the
execution  page hereof and will be entitled to merit  increases  on the basis of
the Company's  consideration  and appraisal of the contributions of the Employee
to the Company's operating  efficiency,  growth,  production and profits, on his
normal  annual  review  date  during  the  period of his  employment  under this
Agreement; and

                                       1
<PAGE>


         (b) the Employee  shall be included to the extent  eligible  thereunder
under any and all  employee  benefit  plans  providing  benefits  for all of the
Company's employees.

         [The Company may, in its discretion,  determine to include the Employee
in short term  incentive,  long term  incentive,  and other benefit plans of the
Company, in accordance with the terms thereof.]

    All  compensation  paid hereunder  shall be subject to any and all necessary
withholdings  and deductions for Social  Security taxes,  income taxes,  and the
like and any elective  deductions  or  deferrals  under the  Company's  employee
benefit plans, and shall be paid in equal  installments,  based upon the payroll
period  established  by the  Company  for  employees  exempt from the Fair Labor
Standards Act.

    4.  Expenses.  The  Employee  is  authorized  to incur  reasonable  business
expenses necessary in the performance of his duties hereunder, including travel,
meal and  lodging  expenses,  provided  such  expenses  have  been  incurred  in
conformity with the Company's  policy  prevailing from time to time for all such
business expenses.  The Employee shall provide the Company documentary  evidence
in form  reasonably  required by the Company to confirm  the  propriety  of such
expenses  and to enable the  Company,  to the extent  possible,  to deduct  such
expenses for federal and state income tax purposes.

    5.   Termination.

         (a) The Company shall have the right to terminate the employment of the
Employee with or without  cause.  If the Company shall  terminate the Employee's
employment for cause,  the Company shall deliver to him a written notice thereof
and the Company's  obligations under this Agreement to make any further payments
to the Employee shall  thereupon cease and terminate.  As used herein,  the term
"cause"  shall mean any of the  following:  (i) a willful  breach of duty by the
Employee in the course of his employment;  (ii) the Employee's  habitual neglect
of his  duty or  continued  incapacity  to  perform  it;  (iii)  the  Employee's
misappropriation  of any funds or property of the  Company;  (iv) any attempt by
the  Employee  to  obtain  personal  profit  from any  transaction  in which the
Employee has an interest which is adverse to the interest of the Company, unless
the Employee  shall have first  obtained the consent of the Board of  Directors;
(v) the Employee's engagement in any other business,  profession,  or occupation
for compensation or otherwise,  which materially conflicts with the rendition of
services  hereunder,  either  directly or  indirectly,  after being  notified in
writing by the Board of  Directors  to cease  engaging  in such other  business,
profession or  occupation;  (vi) the Employee's  conviction of a felony.  If the
Company shall  terminate  the  Employee's  employment  for any reason other than
cause or his  disability  as  specified  in Section  5(b),  the  Employee  shall
continue to be paid

                                       2
<PAGE>

his  salary  as  provided  herein  until  the  earlier  of the  last  day of the
employment term or his death.

         (b) If the Employee shall become  disabled prior to the last day of the
employment  term so that he is  unable  to  perform  the  regular  duties of his
employment on a full-time  basis,  he shall  continue to receive the same salary
which he was receiving under this Agreement immediately prior to such disability
for a period of twelve (12) calendar months thereafter, or until the last day of
the  employment  term, or until his death,  whichever is the shorter period (the
"Disability  Period"),  provided,  however,  that the Company's obligation under
this  sentence  shall be reduced by any  disability  insurance  received  by the
Employee  for the pay period in question on account of  insurance  coverage  the
premium for which was paid by the Company.  If the Disability  Period ends prior
to the last day of the employment  term and at the end of the Disability  Period
the  Employee is unable to resume his regular  duties  hereunder  on a full-time
basis, the Company shall have the right to terminate his employment hereunder by
notice thereof in writing delivered to him. Upon such termination of employment,
the Company's obligation to make any further payments to the Employee under this
Agreement shall terminate.

         (c) If the  Employee  receives  a payment  under  this  Section  5, the
Employee shall not be entitled to any severance payments that might otherwise be
payable to the Employee.

         (d) Upon  termination of his  employment  for any reason,  the Employee
shall,  except  as  otherwise  required  by law or by the plan  document,  cease
participation  in all  employee  benefit  plans,  fringe  benefit  programs  and
perquisites  maintained  by the Company,  irrespective  of any  continuation  of
salary  payments  under  this  Agreement  beyond  the  date  his  employment  is
terminated.  Nothing  herein,  shall  preclude  the  Company  from  amending  or
terminating any employee benefit plan or fringe benefit program.

    6.   Non-Competition.

         (a) While the  Employee  is employed by the Company and for a period of
one (1) year after the  termination  or  cessation  of such  employment  for any
reason (the "Non-Compete  Period"), the Employee will not directly or indirectly
own any  equity or  option or right to  acquire  any  equity in any  Competitive
Business (as hereinafter defined) or:

              i. Render  services to any  Competitive  Business which involve or
relate to the development, manufacture, marketing, sale, merchandising, leasing,
servicing,  support or  promotion  of any  Competitive  Product (as  hereinafter
defined)  to any  customer  or  prospective  customer  of the  Company  whom the
Employee called,  contacted,  solicited or served while employed by the Company,
for  whose  account  the  Employee   supervised,   monitored  or  was  otherwise
responsible  for 

                                       3

<PAGE>

on behalf of the  Company,  at any time during the 2-year  period  ending on the
date of termination of the Employee's employment by the Company; or

              ii. Solicit,  divert or take away, or attempt to divert or to take
away,  the  business  or  patronage  of (a) any of the clients or  customers  or
prospective  clients or  customers  of the  Company  whom the  Employee  called,
contacted, solicited or served while employed by the Company or (b) any accounts
or prospective accounts of the Company which the Employee supervised, monitored,
or was otherwise responsible for while employed by the Company; or

              iii.  Recruit,  solicit  or induce,  or  attempt  to  induce,  any
employee or employees  of the Company to terminate  their  employment  with,  or
otherwise cease their relationship with, the Company.

         (b) If, after diligent efforts, the Employee is unable within one month
after the termination of his employment with the Company, due principally to the
restrictions contained in this Agreement,  to obtain a position equivalent to or
better than the  Employee's  position  with the Company  with a  Non-Competitive
Business, the Company shall pay to the Employee, on a monthly basis, in advance,
commencing  with the first day of the  second  month  after  termination  of the
Employee's  employment  with the Company,  as additional  consideration  for the
Employee's  obligations under this Agreement, a sum equal to the Employee's base
pay  at  termination,  exclusive  of  extra  compensation,  incentive  payments,
commissions,  bonus or employee  benefits  ("Base Pay"),  for each month of such
unemployment,  until the termination of the Employee's  non-compete  obligations
under  this  Agreement.  Following  the  termination  of his  employment  by the
Company,  the  Employee  shall  notify the Company as to his current  employment
status in  writing  within 15 days after the start of any  calendar  month as to
which he seeks  payment  under  this  Section  6(b).  The  Employee  must,  as a
condition to such payment,  establish to the Company's  reasonable  satisfaction
his diligent efforts to obtain employment with a non-Competitive Business.

         (c) If, after diligent efforts, the Employee is unable within one month
after the termination of his employment with the Company, due principally to the
restrictions  contained  in  this  Agreement,   to  obtain  a  position  with  a
non-Competitive  Business at a rate of compensation  at least  equivalent to his
rate  of  compensation  at  the  time  of his  termination  of  employment,  and
therefore, accepts a position at a lower rate of compensation, the Company shall
pay to the  Employee,  on a monthly basis during the period  beginning  upon the
commencement  of such new  employment  and ending  upon the  termination  of the
Employee's   non-compete   obligations  under  this  Agreement,   as  additional
consideration for the Employee's  obligations under this Agreement,  a sum equal
to the  difference  between  his  monthly  rate of  compensation  at the time of
termination and his monthly rate of compensation

                                       4

<PAGE>

at this new position; provided, that the Company shall not be required to pay in
any month an amount in excess of the Employee's monthly Base Pay at termination.
Following the  termination of his employment by the Company,  the Employee shall
notify the Company as to his current employment status in writing within 15 days
after the start of any calendar  month as to which he seeks  payment  under this
Section 6(c).  The Employee  must, as a condition to such payment,  establish to
the Company's reasonable  satisfaction his diligent efforts to obtain employment
with a  non-Competitive  Business at a compensation  level  commensurate  to his
level with the Company.

         (d) The Company may, at its option, at any time during the first thirty
(30) days  following  termination  upon prior  written  notice to the  Employee,
notify the Employee that it will not make any payments to the Employee  pursuant
to Sections 6(b) or 6(c),  in which event the Employee  shall be relieved of the
non-compete obligations set forth in Section 6(a), other than those set forth in
Sections 6(a)(ii) and 6(a)(iii).

         (e) For the purpose of any stock option agreement held by the Employee,
the Employee's  employment  should not be deemed  terminated  until all payments
under this Agreement close.

         (f) If any  restriction  set  forth in this  Section  6 is found by any
court of competent  jurisdiction to be unenforceable because its extends for too

                                    ARTICLE I

                                  Stockholders

               1. Annual  Meeting - The Board of Directors,  the Chairman or the
President  shall  determine the date,  hour,  place and manner of conducting the
Annual  Meeting,  provided  that such  meeting be  scheduled to occur within six
months  after the end of the fiscal year of the  Corporation.  The  purposes for
which an annual  meeting is to be held, in addition to those  prescribed by law,
the Articles of Organization, or these By-Laws, may be specified by the Board of
Directors,  by the Chairman or by the President.  If no such date for the Annual
Meeting is established or said Meeting has not been held on the date determined,
a special  meeting may be held in place thereof with all the force and effect of
an annual meeting.
               2. Special Meetings - Special meetings of the stockholders may be
called by the Board of Directors, by the Chairman or by the President.  Upon the
written  application of one or more  stockholders  who hold at least ten percent
(10%) of the capital stock entitled to vote at a meeting, special meetings shall
be called by the Clerk, or in case of the death, absence, incapacity, or refusal
of the Clerk, by any other officer of the Corporation.
               3. Place of Meetings - All meetings of the stockholders  shall be
held at the principal office of the Corporation unless a different place (within
the United States) is fixed by the Board of Directors, by the Chairman or by the
President and stated in the notice of the meeting.
               4. Notice of Meetings - A written notice of every meeting, annual
and special, of the stockholders,  stating the date, hour and place thereof, and
the purposes  for which the meeting is to be held,  shall be given by the Clerk,
or by an Assistant Clerk, Secretary, or an Assistant Secretary, if there is one,
or by the person calling the meeting, at least seven days before the meeting, to
each stockholder  entitled to vote thereat and to each stockholder,  who by law,
the Articles of  Organization,  or these By-laws is entitled to such notice,  by
leaving  such notice with him or at his  residence or usual place of business or
by mailing it postage  prepaid and addressed to such  stockholder at his address
as it appears upon the records of the Corporation. Notice need not be given to a
stockholder if a written waiver of notice,  executed before or after the meeting
by such stockholder or by his attorney thereunto  authorized,  is filed with the
records of the meeting.
               5.  Quorum - The  holders of a majority  in interest of all stock
issued,  outstanding,  and  entitled to vote shall be required to  constitute  a
quorum for the  transaction  of  business at all  meetings of the  stockholders.
Stock owned  directly or indirectly  by the  Corporation,  if any,  shall not be
deemed  outstanding  for this purpose.  In the absence of a quorum,  any meeting



                                      -1-
<PAGE>


maybe  adjourned  from time to time,  and the meeting  may be held as  adjourned
without further notice.
               6. Voting and Proxies - Stockholders  entitled to vote shall have
one vote for each share of stock entitled to vote and a  proportionate  vote for
each fractional  share entitled to vote held by them of record  according to the
records of the Corporation,  unless otherwise provided by law or by the Articles
of Organization.  Stockholders  entitled to vote may vote either in person or by
written proxy which need not be sealed or attested.  Proxies shall be filed with
the Clerk of the meeting,  or of any  adjournment  thereof,  before being voted.
Except as otherwise  limited  therein,  proxies  shall entitle the persons named
therein to vote at any  adjournment  of such  meeting.  A proxy with  respect to
stock held in the name of two or more persons  shall be valid if executed by any
one of them unless at or prior to exercise of the proxy the Corporation receives
a  specific  written  notice  to the  contrary  from  any one of  them.  A proxy
purporting to be executed by or on behalf of a stockholder shall be deemed valid
unless  challenged  at or prior  to its  exercise,  and the  burden  of  proving
invalidity shall rest on the challenger.
               No proxy  dated more than six months  before  the  meeting  named
therein shall be valid, and no proxy shall be valid after the final  adjournment
of such  meeting;  provided  however that if a proxy is coupled with an interest
sufficient in law to support an irrevocable power, including without limitation,
an  interest  in the  shares  or in the  Corporation  generally,  it may be made
irrevocable if it so provides.  Such an  irrevocable  proxy need not specify the
meeting  to which it  applies  and it shall be valid and  enforceable  until the
interest terminates, or for such shorter period as the proxy specifies.
               7. Action at Meeting - When a quorum is present at any meeting of
the stockholders, a majority of the stock present or represented and voting on a
matter,  except  where  a  larger  vote is  required  by law,  the  Articles  of
Organization,  or these  By-laws,  shall decide any matter to be voted on by the
stockholders. Any election by stockholders shall be determined by a plurality of
the votes cast by the stockholders  entitled to vote at the election.  No ballot
shall be required for such election unless requested by a stockholder present or
represented  at the meeting and entitled to vote in the  election.  Except where
acting in a fiduciary capacity, the Corporation shall not directly or indirectly
vote any share of its own stock.  No stock shall be voted if any  installment of
the  subscription  therefor  has been duly  demanded by the  Corporation  and is
overdue and unpaid.
               8.  Action   Without   Meeting  -  Any  action  to  be  taken  by
stockholders may be taken without a meeting if all stockholders entitled to vote
on the matter  consent to the action by a writing  filed with the records of the
meetings of  stockholders.  Such consent  shall be treated for all purposes as a
vote at a meeting.



                                   ARTICLE II

                                      -2-
<PAGE>

                             The Board of Directors

               1. Powers - The business of the Corporation shall be managed by a
Board of Directors who may exercise all the powers of the Corporation, except as
otherwise  provided by law, the Articles of Organization,  or these By-laws.  In
the  event of a vacancy  in the Board of  Directors,  the  remaining  Directors,
except as  otherwise  provided by law, may exercise the powers of the full Board
until the vacancy is filled.
               2. Membership and Election - The Board of Directors shall consist
of at least three  members;  except that whenever there shall be less than three
stockholders,  it may consist of as few members as there are  stockholders.  The
exact  number shall be  determined  at each annual  meeting of the  stockholders
(subject to change as provided in this  Article  II). At each annual  meeting of
the  stockholders,  the Directors shall be elected by such  stockholders as have
the  right  to  vote  for the  election  of  Directors.  No  Director  need be a
stockholder.
               3.  Vacancies  - Any vacancy in the Board of  Directors,  however
occurring,  may be filled by the  stockholders or, in the absence of stockholder
action, by vote of a majority of the Directors then in office.
               4.  Enlargement of the Board - The number  constituting the Board
of Directors may be increased and one or more  additional  Directors  elected at
any special meeting of the  stockholders or by the Board of Directors by vote of
a majority of the Directors then in office.
               5. Tenure - Except as otherwise  provided by law, the Articles of
Organization,  or these  By-laws,  Directors  shall hold  office  until the next
Annual Meeting of the  stockholders  and thereafter  until their  successors are
chosen  and  qualified.  Any  Director  may  resign by  delivering  his  written

determination.  A regular meeting of the Directors may be held without a call or
notice at the same place as the Annual Meeting of  stockholders,  or the Special
Meeting held in lieu thereof,  following such meeting of  stockholders  provided
either that every Director is present at the meeting at which the Annual Meeting

Special  meetings  of the  Directors  may be held upon the oral or written  call
therefor  by the  Chairman,  President,  Treasurer,  or two or  more  Directors,

Directors need not specify the purposes of the meeting.

of the Directors  then in office shall  constitute a quorum.  Less than a quorum
may  adjourn  any  meeting  from time to time,  and the  meeting  may be held as
adjourned  without  further  notice.  One or more Directors may participate in a
meeting by means of a conference telephone or similar  communications  equipment
by means of which all persons  participating  in the meeting can hear each other

at which a quorum is present, a majority of those present may take any action on
behalf of the Board of  Directors  except to the extent that a larger  number is

of Directors.  Such consent shall be treated as a vote of the Board of Directors
for all purposes.
               12.  Committees  - The  Board  of  Directors  may,  by  vote of a
majority of the  Directors  then in office,  elect from its number an  Executive
Committee or other  committees and may by like vote delegate thereto some or all
of its powers except those which by law, by the Articles of Organization,  or by
these By-laws it is prohibited from delegating.  In no event shall the following
powers be delegated by the Board of Directors to any  committee  established  by
it:
                  i.    The  power  to  change  the  principal   office  of  the

                  v.    The power to remove  officers from  office or  Directors

                  vi.   The power to authorize  the  payment of any  dividend or
                        distribution to stockholders.
                  vii.  The power to authorize  the  reacquisition  for value of
                        stock of the Corporation.
                  viii. The power to authorize a merger of the Corporation.

Except as the Board of Directors may otherwise determine, any such committee may
make rules for the conduct of its business,  but, unless  otherwise  provided by
the Board of Directors or in such rules, its business  (including the keeping of
a record of its  meetings)  shall be  conducted  as nearly as may be in the same
manner as is provided by these By-laws for the Board of Directors, including the
ability to participate in meetings telephonically, and to act by written consent
in lieu of a meeting as provided in Sections 9 and 11,  respectively.  Each such

               1. Shares Represented by Certificates and Uncertificated Shares -
The Board of Directors may provide by resolution  that some or all of any shares
shall be  uncertificated  shares.  Unless such a  resolution  is  adopted,  each
stockholder shall be entitled to



                                      -7-
<PAGE>

a certificate of the capital stock of the  Corporation  stating the number,  the
class and the  designation of the series,  if any, of the shares held by him, in
such form as may be prescribed from time to time by the Board of Directors. Such
certificate  shall be signed by the  Chairman of the Board,  the  President or a
Vice President and by the Treasurer or an Assistant  Treasurer.  Such signatures
may be facsimile if the  certificate is signed by a Transfer Agent or Registrar,
other than a Director,  officer,  or employee  of the  Corporation.  In case any
officer who has signed or whose facsimile  signature has been placed on any such
certificate  shall have ceased to be such  officer  before such  certificate  is
issued,  it may be issued by the Corporation  with the same effect as if he were
such officer at the time of its issue.  Every  certificate  for shares of stock,
which are subject to any  restriction  on transfer  pursuant to the  Articles of
Organization,  these  By-laws,  or any agreement to which the  Corporation  is a
party,  shall have the  restriction  noted  conspicuously  on the certificate or
shall set forth on its face or back either the full text of the restriction or a
statement  of the  existence  of  such  restriction  and a  statement  that  the
Corporation  will  furnish  a copy of such  restriction  to the  holder  of such
certificate upon written request and without charge.  Every  certificate  issued
when the  Corporation  is  authorized  to issue more than one class or series of
stock  shall  set  forth  on its  face  or  back  either  the  full  text of the
preferences,  voting powers, qualifications,  and special and relative rights of
the shares of each class and series  authorized  to be issued or a statement  of
the existence of such preferences,  powers,  qualifications,  and rights,  and a
statement that the Corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.
               2.  Transfers - Subject to the  restrictions,  if any,  stated or
noted on the stock certificates, shares of stock may be transferred on the books
of the  Corporation by the surrender to the Corporation or its Transfer Agent of
the  certificate   therefor  properly  endorsed  or  accompanied  by  a  written
assignment and power of attorney  properly  executed,  with  necessary  transfer
stamps  affixed,  and with such proof of the  authenticity  of  signature as the
Corporation or its Transfer Agent may reasonably require.  Uncertificated shares
of capital stock of the  Corporation  shall be  transferred  on the books of the
Corporation   upon  the  written   assignment  of  the  record  holder  of  such
uncertificated shares.
               3. Record Holder - Except as may be otherwise required by law, by
the Articles of  Organization,  or by these By-laws,  the  Corporation  shall be
entitled to treat the record  holder of stock as shown on its books as the owner
of such stock for all purposes, including the payment of dividends and the right
to vote with respect  thereto,  regardless  of any  transfer,  pledge,  or other
disposition of such stock,  until the shares have been  transferred on the books
of the  Corporation in accordance  with the  requirements  of these By-laws.  It
shall be the duty of each  stockholder  to notify the  Corporation of his latest
post office address.
               4. Record Date - The Board of Directors may fix in advance a time
of not  more  than  sixty  (60)  days  preceding  the  date  of any  meeting  of
stockholders,  or the date for the payment of any  dividend or the making of any
distribution to stockholders, or the last day on which the consent or dissent of
stockholders  may be effectively  expressed for any purpose,  as the record date
for  determining the  stockholders  having the right to notice of and to vote at
such 


                                      -8-
<PAGE>

meeting,  and any adjournment  thereof, or the right to receive such dividend or
distribution,  or the right to give such consent or dissent.  In such case, only
stockholders   of  record  on  such   record   date  shall   have  such   right,
notwithstanding  any transfer of stock on the books of the Corporation after the
record date. Without fixing such record date, the Board of Directors may for all
or any of such  purposes  close the  transfer  books for all or any part of such
period.  In the event no record  date is fixed  and the  transfer  books are not
closed:  (i) The record date for  determining  stockholders  having the right to
notice  of or to vote at a  meeting  of  stockholders  shall be at the  close of
business on the date next  preceding the day on which notice is given;  and (ii)
The record date for determining  stockholders  for any other purpose shall be at
the  close of  business  on the day on which the  Board of  Directors  acts with
respect thereto.
               5.  Replacement of  Certificates - In case of the alleged loss or
destruction or the mutilation of a certificate of stock, a duplicate certificate
may be issued in place  thereof,  upon such terms as the Board of Directors  may
prescribe.
               6. Issue of Stock - Unless  otherwise voted by the  stockholders,
the whole or any part of any unissued balance of the authorized capital stock of
the  Corporation,  or  the  whole  or  any  part  of any  capital  stock  of the
Corporation  held in its  treasury,  may be issued or disposed of by vote of the
Board of  Directors to such  persons,  in such  manner,  for such  consideration
(whether cash, tangible or intangible property,  services or expenses,  or for a
debt or  note,  or as a stock  dividend),  and on such  terms  as the  Board  of
Directors may determine  from time to time,  without first offering the same for
subscription to stockholders of the Corporation.

                                    ARTICLE V

               Indemnification of Directors, Officers and Others

               The  Corporation  shall  indemnify  each person now or  hereafter
elected or appointed a Director,  officer,  employee or agent of the Corporation
(including  each  person  who  serves at its  request  as a  Director,  officer,
employee or agent of any other  organization  in which the  Corporation  has any
interest as a stockholder,  creditor, or otherwise, or who serves at its request
in any capacity  with respect to any employee  benefit plan) against all expense
reasonably incurred or paid by him in connection with the defense or disposition
of any actual or threatened claim, action, suit, or proceeding (civil, criminal,
or other, including appeals) in which he may be involved as a party or otherwise
by reason of his having served in any such capacity,  or by reason of any action
or  omission or alleged  action or  omission  (including  those  antedating  the
adoption of these By-laws) by him while serving in any such capacity; except for
expense  incurred or paid by him with  respect to: (i) any matter as to which he
shall  have  been  adjudicated  in any  proceeding  not  to  have  acted  in the
reasonable  belief that his action was in the best interests of the Corporation,
or (ii) any  matter  as to which he shall  agree or be  ordered  by any court of
competent  jurisdiction to make payment to the Corporation,  or (iii) any matter
as to which the Corporation  shall be prohibited by law or by order of any court
of competent  jurisdiction  from indemnifying  him. Such  indemnification  shall
include payment by the 



                                      -9-
<PAGE>

Corporation  of  expenses  incurred in  defending a civil or criminal  action or
proceeding  in advance of the final  disposition  of such action or  proceeding,
upon receipt of an undertaking  by the person  indemnified to repay such payment
if he shall  eventually  be  adjudicated  to be not entitled to  indemnification
under these By-laws.
               No matter disposed of by settlement,  compromise, or the entry of
a consent  decree,  nor a judgment of  conviction  or the entry of any plea in a
criminal  proceeding,  shall of itself be deemed an  adjudication  of not having
acted in the reasonable  belief that the action taken or omitted was in the best
interests  of  the  Corporation.  The  term  "expense"  shall  include,  without
limitation,  settlements,  attorneys' fees, costs, judgments,  fines, penalties,
and other liabilities. The right of indemnification herein provided for shall be
severable,  shall be in  addition  to any other  right which any such person may
have or obtain,  shall  continue as to any such person who has ceased to be such
Director or officer  and shall  inure to the  benefit of the heirs and  personal
representatives of any such person.

                                   ARTICLE VI

     SILICON VALLEY BANK

     LOAN AND SECURITY AGREEMENT

BORROWER:  OPTICAL CORPORATION OF AMERICA  
ADDRESS:   7421 ORANGEWOOD AVENUE          
           GARDEN GROVE, CALIFORNIA 92641  
           
DATE:      MAY 27, 1994

THIS LOAN AND  SECURITY  AGREEMENT  is entered  into on the above  date  between
SILICON VALLEY BANK  ("Silicon"),  whose address is 3000 Lakeside  Drive,  Santa
Clara,  California  95054-2895  and the borrower  named above (the  "Borrower"),
whose  chief  executive  office is  located  at the above  address  ("Borrower's
Address").

1. LOANS.

     1.1 Loans.  Silicon, in its reasonable  discretion,  will make loans to the
Borrower  (the  "Loans")  in amounts  determined  by  Silicon in its  reasonable
discretion  up to the amount  ("Credit  Limit")  shown on the  Schedule  to this
Agreement  (the  "Schedule"),  provided no Event of Default and no event  which,
with notice or passage of time or both, would constitute an Event of Default has
occurred.  The Borrower is responsible  for monitoring the total amount of Loans
and other  Obligations  outstanding  from time to time,  and Borrower  shall not
permit the same,  at any time,  to exceed the Credit  Limit.  If at any time the
total of all  outstanding  Loans and all other  Obligations  exceeds  the Credit
Limit,  the Borrower shall  immediately pay the amount of the excess to Silicon,
without notice or demand.

     1.2  Interest.  All Loans and all other  monetary  Obligations  shall  bear
interest at the rate shown on the  Schedule  hereto.  Interest  shall be payable
monthly,  on the due date  shown on the  monthly  billing  from  Silicon  to the
Borrower. Silicon may, in its discretion,  charge interest to Borrower's deposit
accounts maintained with Silicon.

     1.3 Fees. The Borrower shall pay to Silicon a loan  origination  fee in the
amount  shown  on the  Schedule  hereto  concurrently  herewith.  This fee is in
addition  to  all  interest  and  other  sums  payable  to  Silicon  and  is not
refundable.

2.   GRANT OF SECURITY INTEREST.

     2.1 Obligations. The term "Obligations" as used in this Agreement means the
following:  the  obligation to pay all Loans and all interest  thereon when due,
and to pay and  perform  when due all other  present  and  future  indebtedness,
liabilities,  obligations,  guarantees,  covenants,  agreements,  warranties and
representations of the Borrower to Silicon,
<PAGE>

whether joint or several, monetary or non-monetary, and whether created pursuant
to this Agreement or any other present or future agreement or otherwise. Silicon
may, in its discretion,  require that Borrower pay monetary  Obligations in cash
to Silicon,  or charge them to Borrower's Loan account, in which event they will
bear interest at the same rate applicable to the Loans. Silicon may also, in its
discretion,  charge any monetary  Obligations  to  Borrower's  deposit  accounts
maintained with Silicon.

     2.2 Collateral. As security for all Obligations, the Borrower hereby grants
Silicon a continuing  security interest in all of the Borrower's interest in the
types of property described below, whether now owned or hereafter acquired,  and
wherever located (collectively,  the "Collateral"):  (a) All accounts,  contract
rights,  chattel paper,  letters of credit,  documents,  securities,  money, and
instruments,  and  all  other  obligations  now or in the  future  owing  to the
Borrower; (b) All inventory, goods, merchandise,  materials, raw materials, work
in process, finished goods, farm products,  advertising,  packaging and shipping
materials,  supplies, and all other tangible personal property which is held for

Borrower's business, and all warehouse receipts and other documents; and (c) All
equipment, including without limitation all machinery, fixtures, trade fixtures,
vehicles,  furnishings,  furniture,  materials,  tools,  machine  tools,  office

and claims, all rights in all litigation  presently or hereafter pending for any
cause or claim (whether in contract,  tort or otherwise),  and all judgments now
or hereafter  arising  therefrom,  all claims of Borrower against  Silicon,  all
rights to purchase or sell real or personal  property,  all rights as a licensor
or licensee of any kind, all royalties,  licenses, processes, telephone numbers,

(including without limitation credit, liability,  property and other insurance),
and all other rights, privileges and franchises of every kind; (e) All books and
records,  whether  stored on  computers  or  otherwise  maintained;  and (f) All
substitutions,  additions  and  accessions  to  any of the  foregoing,  and  all
products,  proceeds and insurance proceeds of the foregoing,  and all guaranties
of and security for the foregoing;  and all books and records relating to any of
the foregoing.  Silicon's  security interest in any present or future technology
(including patents, trade secrets, and other technology) shall be subject to any
licenses  or rights now or in the future  granted by the  Borrower  to any third
parties in the ordinary  course of  Borrower's  business;  provided  that if the
Borrower proposes to sell, license or grant any other rights with respect to any
technology  in a transaction  that,  in  substance,  conveys a major part of the
economic value of that  technology,  Silicon shall first be requested to release
its security  interest in the same, and Silicon may withhold such release in its
discretion.*

     *The security interest of Silicon is subject to the Intercreditor Agreement
dated  as of MAR.  31,  1994  (the  "Intercreditor  Agreement")  among  Silicon,
Borrower,   Massachusetts   Business  Development   Corporation,   Fleet  Credit
Corporation and Massachusetts Capital Resource Company.

3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

     The  Borrower  represents  and  warrants  to  Silicon as  follows,  and the
Borrower covenants that the following  representations will continue to be true,
and that the Borrower will comply with all of the following covenants:

     3.1 Corporate Existence and Authority.  The Borrower, if a corporation,  is
and will continue to be, duly authorized,  validly existing and in good standing
under the laws of the  jurisdiction  of its  incorporation.  The Borrower is and
will continue to be qualified  and licensed to do business in all  jurisdictions
in which  any  failure  to do so would  have a  material  adverse  effect on the
Borrower.  The  execution,  delivery  and  performance  by the  Borrower of this
Agreement,  and all  other  documents  contemplated  hereby  have  been duly and
validly  authorized,  are  enforceable  against the Borrower in accordance  with
their terms, and do not violate any law or any provision of, and are not grounds
for  acceleration  under,  any agreement or instrument which is binding upon the
Borrower.

     3.2 Name; Trade Names and Styles. The name of the borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule hereto are
all prior names of the  Borrower and all of  Borrower's  present and

<PAGE>

prior trade names. The Borrower shall give Silicon 15 days' prior written notice
before  changing its name or doing  business  under any other name. The Borrower
has  complied,  and will in the future  comply,  with all laws  relating  to the
conduct of business under a fictitious business name.

     3.3 Place of Business; Location of Collateral. The address set forth in the
heading to this Agreement is the Borrower's chief executive office. In addition,
the  Borrower  has places of  business  and  Collateral  is located  only at the
locations  set forth on the Schedule to this  Agreement.  The Borrower will give
Silicon  at least  15 days  prior  written  notice  before  changing  its  chief
executive office or locating the Collateral at any other location.

     3.4 Title to Collateral;  Permitted Liens. The Borrower is now, and will at
all times in the future be, the scale  owner of all the  Collateral,  except for
items of equipment  which are leased by the Borrower.  The Collateral now is and
will remain free and clear of any and all liens,  charges,  security  interests,
encumbrances and adverse claims,  except for the following  ("Permitted Liens"):
(i) purchase  money  security  interests in specific  items of  equipment;  (ii)
leases of specific  items of  equipment;  (iii) liens for taxes not yet payable;
(iv) additional  security interests and liens consented to in writing by Silicon
in its reasonable discretion,  which consent shall not be unreasonably withheld;
and (v) security interests being terminated substantially concurrently with this
Agreement*.  Silicon  will  have the right to  require,  as a  condition  to its
consent  under  subparagraph  (iv)  above,  that the  holder  of the  additional
security  interest or lien sign an  intercreditor  agreement on  Silicon's  then
standard  form,  acknowledge  that the security  interest is  subordinate to the
security  interest  in favor of  Silicon,  and agree  not to take any  action to
enforce its  subordinate  security  interest so long as any  Obligations  remain
outstanding,  and that  the  Borrower  agree  that any  uncured  default  in any
obligation secured by the subordinate security interest shall also constitute an
Event of Default  under this  Agreement.  Silicon now has, and will  continue to
have, a perfected and  enforceable  security  interest in all of the Collateral,
subject only to the Permitted  Liens,  and the Borrower will at all times defend
Silicon and the Collateral against all claims of others.  None of the Collateral
now is or will be affixed to any real  property  in such a manner,  or with such
intent, as to become a fixture.

     *and (vi) the  security  interests  which are subject to the  Intercreditor
Agreement referred to in Section 2.2 above.

     3.5 Maintenance of Collateral. The Borrower will maintain the Collateral in
good working  condition,  and the Borrower will not use the  Collateral  for any
unlawful purpose. The Borrower will immediately advise Silicon in writing of any
material loss or damage to the Collateral.

     3.6 Books and Records. The Borrower has maintained and will maintain at the
Borrower's  Address  complete and  accurate  books and  records,  comprising  an
accounting

                                      -2-

- --------------------------------------------------------------------------------

system in accordance with generally accepted accounting principles.

     3.7 Financial Condition and Statements.  All financial statements now or in
the future  delivered to Silicon have been, and will be,  prepared in conformity
with  generally  accepted  accounting  principles and now and in the future will
completely and * reflect the financial  condition of the Borrower,  at the times
and for the  periods  therein  stated.  Since the last date  covered by any such
statement,  there has been no material adverse change in the financial condition
or  business  of the  Borrower.  The  Borrower  is now and will  continue  to be
solvent.  The Borrower will provide Silicon: (i) within 30 days after the end of
each  month,  a monthly  financial  statement  prepared by the  Borrower,  and a
Compliance Certificate in such form as Silicon shall reasonably specify,  signed
by the Chief Financial Officer of the Borrower, certifying that as of the end of
such  month  the  Borrower  was in full  compliance  with all of the  terms  and
conditions of this Agreement,  and setting forth calculations showing compliance
with  the  financial  covenants  set  forth  on  the  Schedule  and  such  other
information  as  Silicon  shall  reasonably  request;  and (ii)  within 120 days
following  the end of the  Borrower's  fiscal year,  complete  annual  financial
statements,  certified by ** independent certified public accountants acceptable
to Silicon.

     *fairly

     **Deloitte & Touche or other

     3.8 Tax Returns and  Payments;  Pension  Contributions.  The  Borrower  has
timely  filed,  and will timely  file,  all tax returns and reports  required by
foreign federal, state and local law, and the Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes,  assessments,  deposits
and contributions  now or in the future owed by the Borrower.  The Borrower may,
however, defer payment of any contested taxes, provided that the Borrower (i) in
good faith  contests the  Borrower's  obligation to pay the taxes by appropriate
proceedings  promptly and diligently  instituted  and  conducted,  (ii) notifies
Silicon in writing of the commencement of, and any material  development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Co11ateral. The Borrower is
unaware of any claims or adjustments  proposed for any of the  Borrower's  prior
tax years which could result in additional taxes becoming due and payable by the
Borrower. The Borrower has paid, and shall continue to pay all amounts necessary
to fund all present and future pension, profit sharing and deferred compensation
plans in  accordance  with their  terms*,  and the Borrower has not and will not
withdraw from  participation  in, permit partial or complete  termination of, or
permit the  occurrence  of any other event with  respect to, any such plan which
could result in any liability of the Borrower, incuding, without limitation, any
liability to the Pension Benefit  Guaranty  Corporation or its successors or any

instituted by or against Silicon with respect to any Collateral or in any manner
relating to the Borrower,  the Borrower shall, without expense to Silicon,  make

books and records to the extent that Silicon may deem them reasonably  necessary
in order to prosecute or defend any such suit or proceeding.

     4.8  Verification.   Silicon  may,  from  time  to  time,  following  prior

- --------------------------------------------------------------------------------

     5.3  Payment  of  Obligations.  On the  Maturity  Date  or on  any  earlier
effective  date of  termination,  the Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such  Obligations  are  otherwise  then due and  payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination,  there are any outstanding letters of
credit  issued by  Silicon  or  issued  by  another  institution  based  upon an
application,  guarantee,  indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such letters of credit plus all  interest,  fees
and cost due or to become  due in  connection  therewith,  to secure  all of the
Obligations  relating  to said  letters of credit,  pursuant to  Silicon's  then
standard form cash pledge  agreement.  Notwithstanding  any  termination of this
Agreement,  all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this  Agreement  shall continue in full force and
effect until all  Obligations  have been paid and  performed  in full;  provided
that,  without  limiting  the fact that  Loans  are  subject  to the  reasonable
discretion of Silicon,  Silicon may, in its sole discretion,  refuse to make any
further  Loans  after  termination.  No  termination  shall in any way affect or
impair any right or remedy of Silicon,  nor shall any such  termination  relieve
the Borrower of any  Obligation to Silicon,  until all of the  Obligations  have
been paid and performed in full. Upon payment and performance in full of all the
Obligations,   Silicon  shall  promptly  deliver  to  the  Borrower  termination
statements,  requests  for  reconveyances  and such  other  documents  as may be
required to fully terminate any of Silicon's security interests.

limits his subordination agreement; or (l) there shall be a change in the record
or  beneficial  ownership of an  aggregate  of more than 20% of the  outstanding

hereof,  without the prior written consent of Silicon; or (m) the Borrower shall
generally not pay its debts as they become due; or the Borrower  shall  conceal,
remove or transfer  any part of its  property,  with intent to hinder,  delay or

law*.  Silicon may cease making any Loans hereunder during any of the above cure
periods, and thereafter if an Event of Default has occurred.

     *; or (n) if any default or event of default occurs and is continuing under
any document or instrument  evidencing or relating to any indebtedness  which is
subordinated  in whole or in part to the  Obligations  or which is  secured by a
security interest in any of the Collateral, unless the same is waived in writing
by the holder thereof

     6.2 Remedies.  Upon the occurrence of any Event of Default, and at any time
thereafter,  Silicon,  at its option,  and without  notice or demand of any kind
(all of which are hereby  expressly  waived by the Borrower),  may do any one or
more of the following:  (a) Cease making Loans or otherwise  extending credit to
the  Borrower  under this  Agreement  or any other  document or  agreement;  (b)

- --------------------------------------------------------------------------------

allowed by any  instrument  evidencing or relating to any  Obligation;  (c) Take
possession  of any or all of the  Collateral  wherever it may be found,  and for
that purpose the Borrower hereby authorizes  Silicon without judicial process to
enter onto any of the Borrower's  premises  without  interference to search for,
take possession of, keep, store, or remove any of the Collateral,  and remain on
the premises or cause a custodian to remain on the premises in exclusive control
thereof  without charge for so long as Silicon deems it reasonably  necessary in
order to complete  the  enforcement  of its rights  under this  Agreement or any
other agreement;  provided, however, that should Silicon seek to take possession
of  any or  all  of  the  Collateral  by  Court  process,  the  Borrower  hereby
irrevocably  waives:  (i) any bond and any surety or security  relating  thereto
required  by any  statute,  court  rule  or  otherwise  as an  incident  to such
possession; (ii) any demand for possession prior to the commencement of any suit
or action to recover possession thereof;  and (iii) any requirement that Silicon
retain possession of and not dispose of any such Collateral until after trial or

which are reasonably  convenient to Silicon and the Borrower,  and to remove the
Collateral to such locations as Silicon may deem advisable; (e) Require Borrower

respect to all accounts and general  intangibles,  together  with any  necessary
indorsements,  within  one day  after the date  received  by the  Borrower;  (f)
Complete the processing,  manufacturing  or repair of any Collateral  prior to a

Silicon shall have the right to use the Borrower's premises,  vehicles,  hoists,
lifts, cranes,  equipment and all other property without charge; (g) Sell, lease
or  otherwise  dispose of any of the  Collateral  in its  condition  at the time
Silicon obtains possession of it or after further  manufacturing,  processing or
repair,  at any one or more public and/or private sales, in lots or in bulk, for
cash,  exchange or other  property,  or on credit,  and to adjourn any such sale
from  time to time  without  notice  other  than oral  announcement  at the time
scheduled for sale.  Silicon shall have the right to conduct such disposition on
the Borrower's  premises without charge, for such time or times as Silicon deems
reasonable,  or on Silicon's premises,  or elsewhere and the Collateral need not
be located at the place of  disposition.  Silicon  may  directly  or through any
affiliated  company  purchase  or  lease  any  Collateral  at  any  such  public
disposition,   and  if  permissible   under   applicable  law,  at  any  private

instruments and other  documents,  to take possession of and open mail addressed
to the Borrower and remove therefrom payments made with respect to any item

grant extensions of time to pay,  compromise  claims and settle accounts and the
like for less than face value;  (i) Offset against any sums in any of Borrower's
general,  special or other deposit  accounts  with  Silicon;  and (j) Demand and
receive possession of any of the Borrower's federal and state income tax returns
and the books and  records  utilized  in the  preparation  thereof or  referring
thereto.  All reasonable  attorneys'  fees,  expenses,  costs,  liabilities  and
obligations  incurred by Silicon with respect to the foregoing shall be added to
and  become  part of the  Obligations,  shall be due on  demand,  and shall bear
interest at a rate equal to the highest  interest rate  applicable to any of the
Obligations.  Without  limiting any of Silicon's  rights and remedies,  from and
after the occurrence of any Event of Default*,  the interest rate  applicable to
the Obligations shall be increased by an additional four percent per annum.

     *and written notice thereof to Borrower

     6.3 Standards for Determining Commercial  Reasonableness.  The Borrower and
Silicon  agree that a sale or other  disposition  (collectively,  "sale") of any
Collateral  which  complies with the following  standards will  conclusively  be
deemed to be  commercially  reasonable:  (i)  Notice of the sale is given to the
Borrower  at least  seven days prior to the sale,  and,  in the case of a public
sale,  notice of the sale is  published at least seven days before the sale in a
newspaper  of  general  circulation  in  the  county  where  the  sale  is to be
conducted*;  (ii)  Notice  of the sale  describes  the  collateral  in  general,
non-specific  terms;  (iii)  The  sale is  conducted  at a place  designated  by
Silicon,  with or without the Collateral being present;  (iv) The sale commences
at any time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in
cash or by cashier's  check or wire  transfer is required;  (vi) With respect to
any sale of any of the Collateral,  Silicon may (but is not obligated to) direct
any  prospective  purchaser to ascertain  directly from the Borrower any and all
information  concerning  the same.  Silicon may employ other methods of noticing
and  selling  the  Collateral,  in its  discretion,  if  they  are  commercially
reasonable.

     *and,  if different,  the county in which the  Borrower's  chief  executive
office  (presently  Orange County,  California) and principal office  (presently
Middlesex County, Massachusetts) are located.

     6.4 Power of Attorney. Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies,  the Borrower grants to Silicon an
irrevocable  power  of  attorney  coupled  with  an  interest,  authorizing  and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without  obligation,  with or without notice to the
Borrower,  and at the Borrower's expense, to do any or all of the following,  in
the  Borrower's  name or  otherwise:  (a) Execute on behalf of the  Borrower any
documents that Silicon may, in its sole and absolute discretion,  deem advisable
in order to perfect and maintain  Silicon's security interest in the Collateral,
or in order to exercise a right of the Borrower or Silicon, or in order to fully
consummate all the transactions contemplated


                                       -6-

- --------------------------------------------------------------------------------

under this Agreement,  and all other present and future agreements;  (b) Execute
on behalf of the Borrower any document exercising, transferring or assigning any
option to  purchase,  sell or  otherwise  dispose  of or to lease (as  lessor or
lessee) any real or personal  property which is part of Silicon's  Collateral or
in which  Silicon has an interest;  (c) Execute on behalf of the  Borrower,  any
invoices  relating to any account,  any draft against any account debtor and any
notice to any account  debtor,  any proof of claim in bankruptcy,  any Notice of
Lien,  claim of  mechanic's,  materialman's  or other  lien,  or  assignment  or
satisfaction of mechanic's, materialman's or other lien; (d) Take control in any
manner of any cash or  non-cash  items of payment  or  proceeds  of  Collateral;
endorse the name of the Borrower upon any instruments, or documents, evidence of
payment or Collateral that may come into Silicon's  possession;  (e) Endorse all
checks and other forms of remittances  received by Silicon;  (f) Pay, contest or
settle any lien, charge, encumbrance,  security interest and adverse claim in or
to any of the Collateral,  or any judgment based thereon,  or otherwise take any
action to terminate or discharge the same; (g) Grant  extensions of time to pay,
compromise claims and settle accounts and general intangibles for less than face
value and execute all releases and other documents in connection therewith;  (h)
Pay any sums  required  on  account  of the  Borrower's  taxes or to secure  the
release of any liens therefor, or both; (i) Settle and adjust, and give releases
of, any insurance claim that relates to any of the Collateral and obtain payment
therefor; (j) Instruct any third party having custody or control of any books or
records  belonging  to, or relating  to, the  Borrower to give  Silicon the same
rights of access and other rights with respect thereto as Silicon has under this
Agreement;  and (k) Take any  action  or pay any sum  required  of the  Borrower
pursuant to this Agreement and any other present or future  agreements.  Silicon
shall exercise the foregoing powers in a commercially reasonable manner. Any and
all  reasonable  sums  paid  and  any  and  all  reasonable   costs,   expenses,
liabilities, obligations and attorneys' fees incurred by Silicon with respect to
the  foregoing  shall be added to and become part of the  Obligations,  shall be
payable  on  demand,  and shall bear  interest  at a rate  equal to the  highest
interest rate applicable to any of the Obligations.  In no event shall Silicon's
rights under the  foregoing  power of attorney or any of Silicon's  other rights
under this  Agreement  be deemed to indicate  that  Silicon is in control of the
business, management or properties of the Borrower.

     6.5  Application  of Proceeds.  All proceeds  realized as the result of any
sale of the Collateral shall be applied by Silicon first to the costs, expenses,
liabilities, obligations and attorneys' fees incurred by Silicon in the exercise
of its rights under this  Agreement,  second to the interest due upon any of the
Obligations,  and third to the  principal of the  Obligations,  in such order as
Silicon shall determine in its sole discretion. Any surplus shall be paid to the
Borrower or other persons legally entitled  thereto;  the Borrower  shall remain
liable to Silicon  for any  deficiency.  If,  Silicon,  in its sole  discretion,
directly  or  indirectly   enters  into  a  deferred  payment  or  other  credit
transaction with any purchaser at

<PAGE>

any sale or other  disposition  of  Collateral,  Silicon  shall have the option,
exercisable  at any  time,  in its  sole  discretion,  of  either  reducing  the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Silicon of the cash therefor.

     6.6 Remedies  Cumulative.  In addition to the rights and remedies set forth
in this Agreement, Silicon shall have all the other rights and remedies accorded
a secured party under the California Uniform Commercial Code and under all other
applicable  laws,  and under any other  instrument  or  agreement  now or in the
future entered into between Silicon and the Borrower, and all of such rights and
remedies are cumulative and none is exclusive.  Exercise or partial  exercise by
Silicon  of one or more  of its  rights  or  remedies  shall  not be  deemed  an
election,  nor bar Silicon from subsequent  exercise or partial  exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver  thereof,  but all rights and remedies
shall continue in full force and effect until all of the  Obligations  have been
fully paid and performed.

7.   GENERAL PROVISIONS.

     7.1  Notices.  All  notices to be given  under this  Agreement  shall be in

certified mail return receipt requested, addressed to Silicon or the Borrower at

days  following  the deposit  thereof in the United  States  mail,  with postage
prepaid.

not affect the remainder of this  Agreement,  which shall continue in full force
and effect.

documents  and  instruments  as may be executed in  connection  herewith are the

Credit Limit        An amount not to exceed the lesser of: (i) $4,000,000 at any one time outstanding; or (ii) 80% of the Net Amount
(Section 1.1):      of Borrower's accounts, which Silicon in its discretion deems eligible for borrowing. "Net Amount" of an account
                    means the gross amount of the account, minus all applicable sales, use, excise and other similar taxes and minus
                    all  discounts,  credits and  allowances of any nature  granted or claimed.

                    Without  limiting the fact that the  determination  of which  accounts are eligible for borrowing is a matter of
                    Silicon's  discretion,  the following will not be deemed eligible for borrowing:  accounts  outstanding for more
                    than 90 days from the invoice date, accounts subject to any contingencies, accounts owing from an account debtor
                    outside the United States or Canada (unless pre-approved by Silicon in its discretion,  or backed by a letter of
                    credit satisfactory to Silicon, or FCIA insured satisfactory to Silicon), accounts owing from one account debtor
                    to the extent they exceed 25% of the total  eligible  accounts  outstanding  (except  that in the case of Martin
                    Marietta  said  percentage  shall be 35%),  accounts  owing from an affiliate of Borrower,  accounts  owing from
                    governmental  agencies or entities to the extent they exceed  $300,000 in the  aggregate  (unless  there as been
                    compliance  with  applicable  statutes,  rules and  regulations  with respect to the assignment of  governmental
                    claims), and accounts owing from an account debtor to whom Borrower is or may be liable for goods purchased from
                    such account debtor or otherwise (other than by reason of taxes owing from the Borrower to a governmental entity
                    or agency). In addition, if more than 50% of the accounts owing from an account debtor are outstanding more than
                    90 days from the invoice date or are otherwise not eligible accounts,  then all accounts owing from that account
                    debtor will be deemed ineligible for borrowing.



Letter of Credit Sublimit 
                    Silicon, in its reasonable discretion, will from time to time during the term of this Agreement issue letters of
                    credit for the account of the Borrower ("Letters of Credit"), in an aggregate amount at any one time outstanding
                    not to exceed $1,000,000, upon the request of the Borrower, provided that, on the date the Letters of Credit are
                    to be issued,  Borrower  has  available to it Loans in an amount equal to or greater than the face amount of the
                    Letters of Credit to be issued.

                                                                 -1-

                    Prior to the issuance of any Letters of Credit,  Borrower shall execute and deliver to Silicon  Applications for
                    Letters of Credit and such other documentation as Silicon shall specify (the "Letter of Credit  Documentation").
                    Fees for the Letters of Credit  shall be as provided in the Letter of Credit  Documentation.

                    The Credit Limit set forth above and the Loans  available  under this  Agreement at any time shall be reduced by
                    the face amount of Letters of Credit from time to time outstanding.

Interest Rate       A rate equal to the "Prime Rate" in effect from time to time, plus 2% per annum. Interest shall be calculated on
(Section 1.2):      the basis of a 360-day year for the actual number of days elapsed.  "Prime Rate" means the rate  announced  from
                    time to time by Silicon as its "prime  rate;" it is a base rate upon which  other  rates  charged by Silicon are
                    based,  and it is not  necessarily  the best rate  available at Silicon.  The interest  rate  applicable  to the
                    Obligations shall change on each date there is a change in the Prime Rate.

                    In the event the Borrower has two  consecutive  fiscal  quarters in which it realizes net income and  Borrower's
                    ratio of Debt to  Tangible  Net Worth,  as of the most  recent  month  end,  is not more than 1.0 to 1, then the
                    interest rate shall be reduced to rate equal to the "Prime Rate" in effect from time to time, plus 1% per annum.
                    The foregoing interest rate reduction shall go into effect following Silicon's review and approval of Borrower's
                    financial statements showing Borrower is entitled to such rate reduction.  Notwithstanding the foregoing,  in no
                    event shall an interest  rate  reduction  go into  effect if, at the date it is to go into  effect,  an Event of
                    Default has occurred.

Loan Origination Fee
(Section 1.3):      $30,000,  payable $10,000 upon commitment,  $5,000 concurrently herewith, and $15,000 (the "$15,000 Balance") on
                    the earlier of the July 31, 1995 or termination of this Agreement (including without limitation termination as a
                    result of an Event of Default).  If the Borrower meets its projections for its fiscal year ending June 30, 1995,
                    previously delivered to Silicon, and this Loan Agreement is then in effect,  Silicon agrees to waive the $15,000
                    Balance.

STOCK (PAR VALUE $.01 PER SHARE) OF     INITIAL EXERCISE PRICE: $11.00 PER SHARE
OPTICAL CORPORATION OF AMERICA

THIS WARRANT  CERTIFIES  THAT,  for the agreed upon value of $1.00 and for other
good and valuable  consideration,  SILICON VALLEY BANK ("Holder") is entitled to
purchase  the  number of fully  paid and  non-assessable  shares of the class of
securities  (the  "Shares") of the  corporation  (the  "Company") at the initial
exercise  price per Share (the  "Warrant  Price")  all as set forth above and as
adjusted  pursuant to Article 2 of this Warrant,  subject to the  provisions and
upon the terms and conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

     1.1 Method of Exercise.  Holder  may exercise  this Warrant by delivering a
duly executed Notice of Exercise in substantially  the form attached as Appendix
I to the principal  * office of the Company.  Unless  Holder is  exercising  the
conversion  right set forth in Section  1.2,  Holder  shall also  deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     *chief executive

     1.2 Conversion  Right.  In lieu of  exercising this Warrant as specified in
Section 1.l,  Holder may from time to time convert this Warrant,  in whole or in
part,  into a number of Shares  determined  by dividing (a) the  aggregate  fair
market value of the Shares or other securities  otherwise issuable upon exercise
of this  Warrant  minus the  aggregate  Warrant  Price of such Shares by (b) the
fair  market  value of  one Share.  The fair market value of the Shares shall be
determined pursuant Section 1.4.

     1.4 Fair Market  Value.  If the Shares are traded in a public  market,  the
fair market value of the Shares shall be the closing price of the Shares (or the
closing  price of the  Company's  stock into  which the Shares are  convertible)
reported for the business day  immediately  before Holder delivers its Notice of
Exercise to the Company.  If the Shares are not traded in a public  market,  the
Board of  Directors  of the Company  shall  determine  fair market  value in its
reasonable  good  faith  judgment.  The  foregoing  notwithstanding,  if  Holder
advises  the Board of  Directors  in writing  that  Holder  disagrees  with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment  banking firm to undertake such  valuation.  If the valuation of such
investment banking firm

<PAGE>

is greater than that  determined  by the Board of  Directors,  then all fees and
expenses of such  investment  banking firm shall be paid by the Company.  In all
other circumstances, such fees and expenses shall be paid by Holder.

     1.5  Delivery  of  Certificate  and New  Warrant.   Promptly  after  Holder
exercises  or  converts  this  Warrant,  the  Company  shall  deliver  to Holder
certificates  for the Shares  acquired  and, if this  Warrant has not been fully
exercised  or  converted  and has not expired,  a new Warrant  representing  the
Shares not so acquired.

     1.6 Replacement of Warrants. On receipt of evidence reasonably satisfactory
to the Company of the loss,  theft,  destruction  or  mutilation of this Warrant
and, in the case of loss,  theft or  destruction,  on  delivery of an  indemnity
agreement  reasonably  satisfactory in form and amount to the Company or, in the
case of mutilation,  or surrender and cancellation of this Warrant,  the Company
at its expense shall execute and deliver, in lieu of this Warrant, a new warrant
of like tenor.

     1.7 Repurchase on Sale, Merger or Consolidation of the Company.

     1.7.1. "Acquisition". For the purpose of  this Warrant, "Acquisition" means
any sale,  license,  or other  disposition  of all or  substantially  all of the
assets of the Company,  or any reorganization,  consolidation,  or merger of the
Company where the holders of the  Company's  securities  before the  transaction
beneficially  own less  than 50% of the  outstanding  voting  securities  of the
surviving entity after the transaction.

     1.7.2.  Assumption of Warrant.  If upon the closing of any  Acquisition the
successor  entity  assumes the  obligations  of this Warrant,  then this Warrant
shall be  exercisable  for the same  securities,  cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares

                                      -1-

                                                   Warrant to Purchase Stock
             -------------------------------------------------------------------

were outstanding on the record date for the Acquisition and subsequent  closing.
The Warrant Price shall be adjusted accordingly.

     1.7.3. Nonassumption.  If upon the closing of any Acquisition the successor
entity  does not  assume  the  obligations  of this  Warrant  and Holder has not
otherwise  exercised this Warrant in full, then the unexercised  portion of this
Warrant shall be deemed to have been automatically converted pursuant to Section
1.2 and thereafter Holder shall participate in the acquisition on the same terms
as other holders of the same class of securities of the Company.

     1.7.4.  Purchase Right.  Notwithstanding the foregoing,  at the election of
Holder,  the Company shall purchase the unexercised  portion of this Warrant for
cash upon the  closing of any  Acquisition  for an amount  equal to (a) the fair
market  value of any  consideration  that would have been  received by Holder in
consideration of the Shares had Holder exercised the unexercised portion of this
Warrant  immediately  before the record date for  determining  the  shareholders
entitled  to  participate  in the  proceeds  of the  Acquisition.  less  (b) the
aggregate Warrant Price of the Shares, but in no event less than zero.

dividend on its common stock (or the shares if the Shares are  securities  other
than common stock) payable in common stock, or other securities,  subdivides the
outstanding  common  stock  into a greater  amount of common  stock,  or, if the
Shares  are  securities  other than  common  stock,  subdivides  the Shares in a
transaction  that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive,  without cost to Holder,  the total number and kind of securities
to which Holder  would have been  entitled had Holder owned the Shares of record
as of the date the dividend or subdivision occurred.

     2.2 Reclassification,  Exchange or Substitution. Upon any reclassification,
exchange,  substitution,  or other event that  results in a change of the number
and/or class of the  securities  issuable  upon  exercise or  conversion of this
Warrant,  Holder shall be entitled to receive,  upon  exercise or  conversion of
this Warrant,  the number and kind of securities  and property that Holder would
have  received  for the Shares if this  Warrant had been  exercised  immediately
before  such  reclassification,  exchange,  substitution,  or other event.   The
Company or its successor  shall  promptly issue to Holder a new Warrant for such
new securities or other property.  The new Warrant shall provide for adjustments
which shall be as nearly  equivalent as may be  practicable  to the  adjustments
provided for in this Article 2 including,

<PAGE>

without  limitation,  adjustments  to the  Warrant  Price  and to the  number of
securities or property issuable upon exercise of the new Warrant. The provisions
of this  Section  2.2 shall  similarly  apply to  successive  reclassifications,
exchanges, substitutions, or other events.

     2.3  Adjustments  for  Combinations,  Etc.  If the  outstanding  Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or shall be subject to adjustment,
from time to time in the manner set forth on Exhibit A in the event of  Diluting
Issuances (as defined on Exhibit A).

or  through  a  reorganization,   transfer  of  assets,  consolidation,  merger,
dissolution,  issue, or sale of securities or any other voluntary action,  avoid
or seek to  avoid  the  observance  or  performance  of any of the  terms  to be
observed or performed under this Warrant by the Company,  but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article  against  impairment.  If the Company takes any action
affecting  the Shares  other than as  described  above  that  adversely  affects
Holder's rights under this Warrant, the Warrant Price shall be adjusted downward
and the  number  of Shares  issuable  upon  exercise  of this  Warrant  shall be
adjusted  upward  in such a manner  that  the  aggregate  Warrant  Price of this
Warrant is unchanged.

     *Organization

     2.6 Fractional Shares. No fractional Shares shall be issuable upon exercise
or  conversion  of the  Warrant  and the number of Shares to be issued  shall be
rounded down to the nearest whole Share.  If a fractional  share interest arises
upon any exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder an amount computed by multiplying the
fractional interest by the fair market value of a full Share.

     2.7  Certificate  as to  Adjustments.  Upon each  adjustment of the Warrant
Price, the Company at its expense shall promptly  compute such  adjustment,  and
furnish Holder with a certificate of its Chief  Financial  Officer setting forth
such adjustment and the facts upon which such  adjustment is based.  The Company
shall,  upon written  request,  furnish  Holder a certificate  setting forth the
Warrant  Price in effect  upon the date  thereof  and the series of  adjustments
leading to such Warrant Price.

event  exceed the  aggregate  proceeds  received by such Holder from the sale of
Registrable Securities held by such Holder in such registration.

     (c) Each party entitled to  indemnification  under this subsection 1.5 (the
"Indemnified  Party") shall  give  notice  to  the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom;  provided  that  counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the Indemnified Party (whose approval shall not be

- --------------------------------------------------------------------------------

unreasonably  withheld),  and the  Indemnified  Party  may  participate  in such
defense at such party's expense;  and provided further,  that the failure of any
Indemnified  Party to give  notice as  provided  herein  shall not  relieve  the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying  Party; and provided further,  that an Indemnified
Party  (together  with all other  Indemnified  Parties which may be  represented
without  conflict by one  counsel)  shall have the right to retain one  separate
counsel,  with the fees and expenses to be paid by the  Indemnifying  Party,  if
representation  of  such  Indemnified  Party  by  the  counsel  retained  by the
Indemnifying  Party would be inappropriate due to actual or potential  differing
interests between such Indemnified Party and any other party represented by such
counsel in such  proceeding.  No Indemnifying  Party, in the defense of any such
claim or litigation,  shall,  except with the consent of each Indemnified Party,
consent to entry of any  judgment  or enter into any  settlement  which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such  Indemnified  Party of a release  from all  liability in respect to such
claim or iitigation.

     1.6 Information by Holder. Any Holder or Holders of Registrable  Securities
included  in  any  registration  shall  promptly  furnish  to the  Company  such
information  regarding such Holder or Holders and the  distribution  proposed by
such  Holder or Holders as the  Company  may  request in writing and as shall be
required  in  connection  with any  registration,  qualification  or  compliance
referred to herein.

     1.7 Rule 144  Reporting.  With a view to making  available  to Holders  the
benefits of certain rules and  regulations  of the SEC which may permit the sale
of the Registrable  Securities to the public without  registration,  the Company
agrees at all times to:

     (a)  make  and keep  public  information  available,  as  those  terms  are
understood  and defined in SEC Rule 144,  after 90 days after the effective date
of the first registration filed by the Company for an offering of its securities
to the general public;

     (b) file with the SEC in a timely  manner all reports  and other  documents
required of the Company  under the  Securities  Act and the Exchange Act (at any
time after it has become subject to such reporting requirements); and

     (c) so long as a Holder owns any Registrable Securities, to furnish to such
Holder  forthwith  upon  request a written  statement  by the  Company as to its
compliance  with the reporting  requirements of said Rule 144 (at any time after
90 days after the effective date of the first  registration  statement  flied by
the Company for an offering of its securities to the general public), and of the
Securities  Act and the Exchange Act (at any time after it has become subject to
such  reporting  requirements),  a copy of the most recent  annual or  quarterly
report of the  Company,  and such other  reports and  documents  so filed by the
Company as the  Holder may  reasonably  request  in  complying  with any rule or
regulation  of the SEC allowing the Holder to sell any such  securities  without
registration.

                             ANTIDILUTION AGREEMENT

Issuer:              Optical Corporation of America
Address:             7421 Orangewood Avenue
                     Garden Grove, California


Date:                May 27, 1994

THIS  AGREEMENT  is  entered  into as of the above date by and  between  SILICON
VALLEY BANK  ("Purchaser"),  whose address is 3000 Lakeside Drive,  Santa Clara,
California 95054-2895, and the above Company, whose address is set forth above.

                                    RECITALS

     A.  Concurrently  with the execution of this  Antidilution  Agreement,  the
Purchaser  is  purchasing  from the  Company a Warrant  to  Purchase  Stock (the
"Warrant")  pursuant  to  which  Purchaser  has the  right to  acquire  from the
Company the Shares (as defined in the Warrant).

     B. By this Antidilution Agreement,  the Purchaser and the Company desire to
set forth the  adjustment in the number of Shares  issuable upon exercise of the
Warrant  as a result of a  Diluting  Issuance  (as  defined  in Exhibit A to the
Warrant).

     C.  Capitalized  terms used herein shall have the same meaning as set forth
in the Warrant.

     NOW,  THEREFORE,  in consideration  of the mutual  promises,  covenants and
conditions hereinafter set forth, the parties hereto mutually agree as follows:

     1.  Definitions.  As used in this  Antidilution  Agreement,  the  following
terms have the following respective meanings:

     (a)  "Option"  means any  right,  option,  or  warrant  to  subscribe  for,
purchase, or otherwise acquire common stock or Convertible Securities.

     (b) "Convertible Securities" means any evidences of indebtedness, shares of
stock,  or  other  securities   directly  or  indirectly   convertible  into  or
exchangeable for common stock.

     (c) "Issue" means to grant,  issue,  sell, assume, or fix a record date for
determining  persons  entitled to receive,  any  security  (including  Options),
whichever of the foregoing is the first to occur.

<PAGE>

     (d) "Additional  Common Shares" means all common stock (including  reissued
shares) issued (or deemed to be issued  pursuant to Section 2) after the date of
the Warrant.  Additional  Common  Shares does not include,  however,  any common
stock issued in a transaction  described in Sections 2.1 and 2.2 of the Warrant;
any common stock  Issued  upon conversion of preferred stock  outstanding on the
date of the  Warrant;  the Shares;  or common  stock Issued as incentive or in a
nonfinancing  transaction to employees,  officers,  directors, or consultants to
the Company.

     (e) The shares  of common  stock  ultimately Issuable  upon  exercise of an
Option (including the shares of common stock ultimately Issuable upon conversion
or exercise of a Convertible Security Issuable pursuant to an Option) are deemed
to be Issued when the Option is Issued.  The shares of common  stock  ultimately
Issuable upon  conversion or exercise of a  Convertible  Security  (other than a
Convertible  Security  Issued pursuant to an Option) shall be deemed Issued upon
Issuance of the Convertible Security.

     2. Deemed Issuance of Additional Common Shares.  The shares of common stock
ultimately  Issuable upon exercise of an Option  (including the shares of common
stock ultimately Issuable upon conversion or exercise of a Convertible  Security
Issuable  pursuant  to an  Option)  are  deemed to be Issued  when the Option is
Issued.  The shares of common  stock  ultimately  Issuable  upon  conversion  or
exercise of a Convertible  Security  (other than a Convertible  Security  Issued
pursuant to an Option) shall be deemed  Issued upon Issuance of the  Convertible
Security.  The maximum  amount of  common stock  Issuable is determined  without
regard to any future  adjustments  permitted  under the instrument  creating the
Options or Convertible Securities.

               -----------------------------------------------------------------


     3. Adjustment of Warrant Price for Diluting Issuances.

     3.1 Weighted Average  Adjustment.  If the  Company Issues Additional Common
Shares after the date of the Warrant and the consideration per Additional Common
Share  (determined  pursuant to  Section 9)  is  less than the Warrant  Price in
effect  immediately  before such Issue, the Warrant Price in effect  immediately
before  such Issue shall be reduced,  concurrently  with such Issue,  to a price
(calculated to the nearest  hundredth of a cent)  determined by muitiplying  the
Warrant Price by a fraction:

     (a) the  numerator  of which is the  amount  of  common  stock  outstanding
immediately before such Issue plus the amount of common stock that the aggregate
consideration  received by the Company for the  Additional  Common  Shares would
purchase at the Warrant Price in effect immediately before such Issue, and

     (b) the  denominator  of which is the  amount of common  stock  outstanding
immediately before such Issue plus the number of such Additional Common Shares.

     3.2  Adjustment  of Number of Shares.  Upon each  adjustment of the Warrant
Price,  the number of Shares  issuable  upon  exercise of the  Warrant  shall be
increased to equal the quotient  obtained by dividing (a) the product  resulting
from  multiplying (i) the number of Shares issuable upon exercise of the Warrant
and (ii) the Warrant Price,  in each case as in effect  immediately  before such
adjustment, by (b) the adjusted Warrant Price.

     3.3 Securities Deemed  Outstanding.  For the purpose of this Section 3, all
securities issuable upon exercise of any outstanding  Convertible  Securities or
Options, warrants, or other rights to acquire securities of the Company shall be
deemed to be outstanding.

     4. No Adjustment for Issuances Following Deemed Issuances. No adjustment to
the Warrant  Price shall be made upon the exercise of Options or  conversion  of
Convertible Securities.

     5.  Adjustment  Following  Changes  in  Terms  of  Options  or  Convertible
Securities.  If the  consideration  payable to, or the amount  of  common  stock
Issuable by, the Company increases or decreases,  respectively,  pursuant to the
terms of any outstanding  Options or Convertible  Securities,  the Warrant Price
shall be  recomputed  to reflect such  increase or decrease.  The  recomputation
shall be made as of the  time of the  Issuance  of the  Options  or  Convertible
Securities.  Any changes in the Warrant Price that occurred  after such Issuance
because other  Additional  Common Shares were Issued or deemed Issued shall also
be recomputed.

     6. Recomputation Upon Expiration of Options or Convertible Securities.  The
Warrant  Price computed  upon the original Issue of any  Options or  Convertible
Securities,  and any subsequent  adjustments based thereon,  shall be recomputed
when any Options or rights of conversion  under  Convertible  Securities  expire
without having been exercised. In the case of Convertible  Securities or Options

                                                              
<PAGE>


for  common  stock,  the  Warrant  Price  shall  be  recomputed  as if the  only
Additional  Common Shares Issued were the shares of Common stock actually Issued
upon the exercise of such securities,  if any, and as if the only  consideration
received  therefor  was the  consideration  actually  received  upon the  Issue,
exercise or conversion of the Options or Convertible Securities.  In the case of
Options for Convertible Securities,  the Warrant Price shall be recomputed as if
the only Convertible  Securities Issued were the Convertible Securities actually
Issued  upon the  exercise  thereof,  if any,  and as if the only  consideration
received  therefor  was  the  consideration  actually  received  by the  Company
(determined  pursuant to Section  9), if any,  upon the Issue of the Options for
the Convertible Securities.

     7. Limit on Readjustments. No readjustment of the Warrant Price pursuant to
Sections 5 or 6 shall  increase  the  Warrant  Price more than the amount of any
decrease made in respect or the Issue of any Options or Convertible Securities.

     8. 30 Day  Options.  In the case of any Options  that expire by their terms
not more than 30 days after the date of Issue  thereof,  no  adjustment  of the
Warrant  Price  shall be made  until  the  expiration  or  exercise  of all such
Options.

     9. Computation of Consideration.  The consideration received by the Company
for the Issue of any Additional Common Shares shall be computed as follows:

     (a)  Cash   shall  be  valued  at  the  amount  of  cash  received  by  the
Corporation, excluding amounts paid  or  payable for accrued interest or accrued
dividends.

     (b)  Property.  Property  other than  cash  shall be  computed  at the fair
market value thereof at the time of the Issue as determined in good faith by the
Board of Directors of the Company.

     (c) Mixed  Consideration.  The  consideration  for Additional Common Shares
Issued together with other property of the Company for consideration that covers
both shall be determined in good faith by the Board of Directors.

     (d) Options and Convertible  Securities.  The  consideration per Additional
Common  Share for Options and  Convertible  Securities  shall be  determined  by
dividing:

     (i) the total amount, if any, received or receivable by the Company for the
Issue of the  Options or  Convertible  Securities,  plus the  minimum  amount of
additional  consideration  (as set forth in the  instruments  relating  thereto,
without regard to any provision contained therein for a subsequent adjustment of
such  consideration)  payable to the  Company  upon  exercise  of the Options or
conversion of the Convertible Securities, by

     (ii) the  maximum  amount of common stock (as set forth in the  instruments
relating  thereto,  without  regard to any  provision  contained  therein  for a
subsequent adjustment of

such  number)  ultimately  Issuable  upon the  exercise  of such  Options or the
conversion of such Convertible Securities.

     10. General.

     10.1 Governing Law. This  Antidilution  Agreement  shall be governed in all
respects  by the laws of the State of  California  as such laws are  applied  to
agreements  between  California  residents  entered  into  and  to be  performed
entirely within California.

     10.2 Successors and Assigns. Except as otherwise expressly provided herein,

or not,  applications  to  register  and  registrations  of the  same  and  like
protections,  and the entire goodwill of the business of Assignor connected with
and symbolized by such trademarks,  including without limitation those set forth
on Exhibit C attached hereto (collectively, the "Trademarks");

                  (i) Any and all claims for damages by way of past, present and
future  infringements of any of the rights included above, with  the right,  but
not  the  obligation,  to sue for and  collect  such  damages  for  said  use or
infringement of the intellectual property rights identified above;

                  (j) All licenses or other rights to use any of the Copyrights,
Patents or Trademarks,  and all license fees and royalties arising from such use
to the extent permitted by such license or rights;

                  (k) All amendments, extensions, renewals and extensions of any
of the Copyrights, Trademarks or Patents; and

THE INTEREST IN THE COLLATERAL  BEING ASSIGNED  HEREUNDER SHALL NOT BE CONSTRUED
AS A CURRENT  ASSIGNMENT,  BUT AS A CONTINGENT  ASSIGNMENT TO SECURE  ASSIGNOR'S
OBLIGATIONS TO ASSIGNEE UNDER THE LOAN AGREEMENT.

         2. Authorization and Request. Assignor authorizes and requests that the
Register of Copyrights and the  Commissioner  of Patents and  Trademarks  record
this conditional assignment.

         3. Covenants and Warranties.  Assignor represents,  warrants, covenants
and agrees as follows:

                  (a) Assignor is now the sole owner of the  Collateral,  except
for non-exclusive  licenses granted by Assignor to its customers in the ordinary
course of business.

                  (b) Listed on Exhibits A-1 and A-2 are all copyrights owned by
Assignor,  in which  Assignor has an interest,  or which are used in  Assignor's
business.

                  (c) Each employee, agent and/or independent contractor who has
participated  in the creation of the property  constituting  the  Collateral has
either  executed an assignment of his or her rights of authorship to Assignor or
is an employee of Assignor acting within the scope of his or

                                       -2-



<PAGE>

her employment and was such an employee at the time of said creation.

                  (d) All of Assignor's  present and future  software,  computer
programs  and other  works of  authorship  subject  to United  States  copyright
protection,  the  sale,  licensing  or other  disposition  of which  results  in
royalties receivable, license fees receivable, accounts receivable or other sums
owing  to  Assignor  (collectively,  "Receivables"),  have  been  and  shall  be
registered  with the United States  Copyright  Office prior to the date Assignor
requests or accepts any loan from Assignee with respect to such  Receivables and
prior  to the  date  Assignor  includes  any such  Receivables  in any  accounts
receivable  aging,  borrowing base report or certificate or other similar report
provided to Assignee,  and Assignor shall provide to Assignee copies of all such
registrations promptly upon the receipt of the same.

                  (e) Assignor shall undertake all reasonable  measures to cause
its  employees,  agents and  independent  contractors  to assign to Assignor all
rights of authorship to any  copyrighted  material in which  Assignor has or may
subsequently acquire any right or interest.

                  (f)  Performance of this  Assignment does not conflict with or
result in a breach of any  agreement to which  Assignor is bound,  except to the
extent that certain intellectual  property agreements prohibit the assignment of
the rights  thereunder to a third party without the  licensor's or other party's
consent and this Assignment constitutes an assignment.

                  (g)  During  the  term of this  Agreement,  Assignor  will not
transfer  or  otherwise  encumber  any  interest in the  Collateral,  except for
non-exclusive licenses granted by Assignor in the ordinary course of business or
as set forth in this Assignment;

                  (h) Each of the Patents is valid and enforceable,  and no part
of the Collateral has been judged invalid or unenforceable, in whole or in part,
and no claim has been made that any part of the  Collateral  violates the rights
of any third party;

                  (i) Assignor  shall promptly  advise  Assignee of any material
adverse change in the composition of the  Collateral,  including but not limited
to any subsequent ownership right of the Assignor in or to any Trademark, Patent
or Copyright not specified in this Assignment;

                  (j)  Assignor  shall (i)  protect,  defend  and  maintain  the
validity and enforceability of the Trademarks,  Patents and Copyrights, (ii) use
its  best  efforts  to  detect  infringements  of the  Trademarks,  Patents  and
Copyrights  and promptly  advise  Assignee in writing of material  infringements
detected  and (iii)  not allow any  Trademarks,  Patents,  or  Copyrights  to be
abandoned,  forfeited or dedicated to the public without the written  consent of
Assignee,  which shall not be unreasonably  withheld unless Assignor  determines
that reasonable business practices suggest that abandonment is appropriate.

                  (k) Assignor shall  promptly  register the most recent version
of any of Assignor's Copyrights,  if not so already registered,  and shall, from
time to time,  execute and file such other  instruments,  and take such  further
actions  as  Assignee  may  reasonably  request  from time to time to perfect or
continue the perfection of Assignee's interest in the Collateral;

                  (l) This Assignment creates, and in the case of after acquired
Collateral, this Assignment will create at the time Assignor first has rights in
such after acquired Collateral, in favor of Assignee a valid and perfected first
priority  security  interest in the Collateral in the United States securing the
payment and performance of the obligations  evidenced by the Loan Agreement upon
making the filings referred to in clause (m) below;

                  (m) To its  knowledge,  except for, and upon,  the filing with
the United States  Patent and  Trademark  office with respect to the Patents and
Trademarks  and the  Register  of  Copyrights  with  respect  to the  Copyrights
necessary to perfect the security interests and

                                       -3-


<PAGE>

assignment created hereunder and except as has been already made or obtained, no
authorization, approval or other action by, and no notice to or filing with, any
U.S.  governmental  authority or U.S. regulatory body is required either (i) for
the  grant by  Assignor  of the  security  interest  granted  hereby  or for the
execution, delivery or performance of this Assignment by Assignor in the U.S. or
(ii) for the  perfection in the United States or the exercise by Assignee of its
rights and remedies thereunder;

                  (n) All information  heretofore,  herein or hereafter supplied
to  Assignee  by or on behalf of  Assignor  with  respect to the  Collateral  is
accurate and complete in all material respects.

                  (o)  Assignor  shall not enter into any  agreement  that would
materially  impair or conflict with  Assignor's  obligations  hereunder  without
Assignee's  prior  written  consent,  which  consent  shall not be  unreasonably
withheld.  Assignor  shall not permit the inclusion in any material  contract to
which  it  becomes  a party  of any  provisions  that  could or might in any way
prevent the creation of a security interest in Assignor's rights and interest in
any property  included  within the definition of the  Collateral  acquired under
such  contracts,  except that  certain  contracts  may  contain  anti-assignment
provisions that could in effect prohibit the creation of a security  interest in
such contracts.

                  (p) Upon any executive  officer of Assignor  obtaining  actual
knowledge  thereof,  Assignor  will promptly  notify  Assignee in writing of any
event that materially  adversely  affects the value of any material  Collateral,
the ability of Assignor to dispose of any material  Collateral or the rights and
remedies  of  Assignee  in  relation  thereto,  including  the levy of any legal
process against any of the Collateral.

         4.  Assignee's  Rights.  Assignee  shall  have the  right,  but not the
obligation,  to take, at Assignor's  sole expense,  any actions that Assignor is
required under this  Assignment to take but which Assignor fails to take,  after
fifteen (15) days' notice to Assignor.  Assignor  shall  reimburse and indemnify
Assignee  for all  reasonable  costs and  reasonable  expenses  incurred  in the
reasonable exercise of its rights under this section 4.

         5.  Inspection  Rights.  Assignor  hereby  grants to  Assignee  and its
employees,  representatives  and  agents the right to visit,  during  reasonable
hours upon prior  reasonable  written notice to Assignor,  and any of Assignor's
plants and facilities that manufacture,  install or store products (or that have
done so during the prior  six-month  period) that are sold  utilizing any of the
Collateral,  and to inspect the products and quality  control  records  relating
thereto  upon  reasonable  written  notice  to  Assignor  and as often as may be
reasonably  requested,  but not  more  than  one (1) in  every  six (6)  months;
provided,  however,  nothing herein shall entitle  Assignee access to Assignor's
trade secrets and other proprietary information.

         6.  Further Assurances; Attorney in Fact.

                  (a)  Upon  an  Event  of  Default,   on  a  continuing   basis
thereafter,  Assignor  will,  subject to any prior  licenses,  encumbrances  and
restrictions and prospective licenses,  make, execute,  acknowledge and deliver,
and file and record in the  proper  filing  and  recording  places in the United
States, all such instruments,  including, appropriate financing and continuation
statements and  collateral  agreements and filings with the United States Patent
and Trademarks  Office and the Register of Copyrights,  and take all such action
as may reasonably be deemed necessary or advisable, or as requested by Assignee,
to  perfect  Assignee's  security  interest  in  all  Copyrights,   Patents  and
Trademarks and otherwise to carry out the intent and purposes of this Collateral
Assignment,  or for assuring and  confirming to Assignee the grant or perfection
of a security interest in all Collateral.

                  (b) Upon an  Event of  Default,  Assignor  hereby  irrevocably
appoints  Assignee as Assignor's  attorney-in-fact,  with full  authority in the
place and stead of Assignor and in the

                                      -4-

<PAGE>

name of  Assignor,  Assignee  or  otherwise,  from  time  to time in  Assignee's
discretion,  upon  Assignor's  failure or inability to do so, to take any action
and to execute any instrument  which Assignee may deem necessary or advisable to
accomplish the purposes of this Collateral Assignment, including:

                  (i)  To  modify,  in  its  sole  discretion,  this  Collateral
Assignment without first obtaining  Assignor's  approval of or signature to such
modification by amending  Exhibit A-l,  Exhibit A-2,  Exhibit A-3, Exhibit B and
Exhibit C, thereof, as appropriate,  to include reference to any right, title or
interest in any Copyrights, Patents or Trademarks acquired by Assignor after the
execution  hereof or to delete any reference to any right,  title or interest in
any Copyrights,  Patents or Trademarks in which Assignor no longer has or claims
any right, title or interest; and

                  (ii) To file, in its sole discretion, one or more financing or
continuation  statements  and  amendments  thereto,   relative  to  any  of  the
Collateral without the signature of Assignor where permitted by law.

         7. Events of Default.  The  occurrence  of any of the  following  shall
constitute an Event of Default under the Assignment:

                  (a) An Event of Default occurs under the Loan Agreement; or

                  (b)  Assignor  breaches  any  warranty  or  agreement  made by
Assignor in this Assignment.

         8.  Remedies.  Upon  the  occurrence  and  continuance  of an  Event of
Default, Assignee shall have the right to exercise all the remedies of a secured
party under the California Uniform Commercial Code, including without limitation
the right to require  Assignor  to  assemble  the  Collateral  and any  tangible
property in which  Assignee has a security  interest and to make it available to
Assignee at a place designated by Assignee.  Assignee shall have a nonexclusive,
royalty free license to use the Copyrights, Patents and Trademarks to the extent
reasonably necessary to permit Assignee to exercise its rights and remedies upon
the occurrence of an Event of Default. Assignor will pay any expenses (including
reasonable attorney's fees) incurred by Assignee in connection with the exercise
of any of Assignee's rights hereunder,  including without limitation any expense
incurred in disposing of the Collateral.  All of Assignee's  rights and remedies
with respect to the Collateral shall be cumulative.

         9. Indemnity.  Assignor  agrees to defend,  indemnify and hold harmless
Assignee and its officers,  employees,  and agents against: (a) all obligations,
demands,  claims,  and  liabilities  claimed or asserted by  any other  party in
connection with the  transactions  contemplated  by this Agreement,  and (b) all
losses or  expenses  in any way  suffered,  incurred,  or paid by  Assignee as a
result  of or  in  any  way  arising  out  of,  following  or  consequential  to
transactions  between  Assignee and Assignor,  whether under this  Assignment or
otherwise   (including  without  limitation,   reasonable   attorneys  fees  and
reasonable expenses),  except for losses arising form or out of Assignee's gross
negligence or willful misconduct.

         10. Release.  At such time as Assignor shall completely  satisfy all of
the  obligations  secured  hereunder,  Assignee  shall  execute  and  deliver to
Assignor all assignments and other instruments as may be reasonably necessary or
proper to terminate  Assignee's security interest in the Collateral,  subject to
any disposition of the Collateral which may have been made by Assignee  pursuant
to this Agreement.  For the purpose of this Agreement,  the obligations  secured
hereunder  shall be deemed to continue if Assignor enters into any bankruptcy or
similar  proceeding at a time when any amount paid to Assignee  could be ordered
to be repaid as a preference or pursuant to a similar theory, and shall continue
until it is finally determined that no such repayment can be ordered.

                                       -5-

         11. No Waiver. No course of dealing between Assignor and Assignee,  nor
any failure to exercise  nor any delay in  exercising,  on the part of Assignee,
any right,  power, or privilege under this Agreement or under the Loan Agreement
or any other agreement, shall operate as a waiver. No single or partial exercise
of any  right,  power,  or  privilege  under  this  Agreement  or under the Loan
Agreement or any other agreement by Assignee shall preclude any other or further
exercise of such right,  power, or privilege or the exercise of any other right,
power, or privilege by Assignee.

         12. Rights Are Cumulative.  All of Assignee's  rights and remedies with
respect  to the  Collateral  whether  established  by this  Agreement,  the Loan
Agreement,  or any other documents or agreements,  or by law shall be cumulative
and may be exercised concurrently or in any order.

         13.  Course of  Dealing.  No  course of  dealing,  nor any  failure  to
exercise,  nor any delay in exercising any right,  power or privilege  hereunder
shall operate as a waiver thereof.

         14.  Attorneys'  Fees.  If any action  relating to this  Assignment  is
brought by either party hereto  against the other party,  the  prevailing  party
shall be entitled to recover reasonable attorneys fees, costs and disbursements.

         15.  Amendments.  This  Assignment  may be  amended  only by a  written
instrument  signed by both parties  hereto.  To the extent that any provision of
this Agreement conflicts with any provision of the Loan Agreement, the provision
giving  Assignee  greater rights or remedies shall govern,  it being  understood
that the  purpose of this  Agreement  is to add to, and not  detract  from,  the
rights granted to Assignee under the Loan Agreement.  This  Agreement,  the Loan
Agreement,  and the documents  relating thereto comprise the entire agreement of
the parties with respect to the matters addressed in this Agreement.

         16.  Severability.  The provisions of this Agreement are severable.  If
any provision of this Agreement is held invalid or  unenforceable in whole or in
part in any jurisdiction,  then such invalidity or unenforceability shall affect
only such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other  jurisdiction,  or any
other provision of this Agreement in any jurisdiction.

         17.  Counterparts.  This  Assignment  may be  executed  in two or  more
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together shall constitute the same instrument.

         18. California Law and Jurisdiction.  This Assignment shall be governed
by the  laws of the  State of  California,  without  regard  for  choice  of law
provisions.  Assignor and Assignee consent to the  nonexclusive  jurisdiction of
any state or federal court located in Orange County, California.

         19. Confidentiality. In handling any confidential information, Assignee
shall exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of any
non-public  information thereby received or received pursuant to this Assignment
except that the disclosure of this information may be made (i) to the affiliates
of the Assignee,  (ii) to prospective transferee or purchasers of an interest in
the  obligations  secured  hereby,  provided  that  they  have  entered  into  a
comparable  confidentiality  agreement in favor of Assignor and have delivered a
copy to Assignor, (iii) as required by law, regulation,  rule or order, subpoena
judicial  order or similar order and (iv) as may be required in connection  with
the examination, audit or similar investigation of Assignee.

         20.  WAIVER OF RIGHT TO JURY TRIAL.  ASSIGNEE AND ASSIGNOR EACH HEREBY

ARISING OUT OF, OR IN ANY WAY RELATING TO: (I) THIS AGREEMENT; OR (II) ANY OTHER
PRESENT OR FUTURE  INSTRUMENT OR AGREEMENT  BETWEEN  ASSIGNEE AND  ASSIGNOR;  OR
(III) ANY  CONDUCT,  ACTS OR  OMISSIONS  OF ASSIGNEE OR ASSIGNOR OR ANY OF THEIR
DIRECTORS,   OFFICERS,   EMPLOYEES,  AGENTS,  ATTORNEYS  OR  ANY  OTHER  PERSONS
AFFILIATED WITH ASSIGNEE OR ASSIGNOR;  IN EACH OF THE FOREGOING  CASES,  WHETHER

day and year first above written.

equal to the sum of (i) Three and Sixty-Six  Hundreths percent (3.66%) per annum
plus (ii) a variable  per annum  interest  rate which shall be equal to the rate
listed for  "l-Month"  Commercial  Paper under the column  indicating an average
rate as stated in the Federal  Reserve  Statistical  Release  H.15 (519) for the
second  calendar month ("Current CPR") preceding the calendar month in which the
Adjustment Period commences. If, for any reason whatsoever,  the Federal Reserve
Statistical Release H.13 (519) is no longer published,  the Current CPR shall be
equal to the latest  Commercial  Paper Rate for high grade unsecured notes of 30
days maturity sold through dealer by major  corporations in multiples of $1,000,
as indicated in the "Money  Rates"  column of the Wall Street  Journal,  Eastern
Edition, published on the first Business Day of the calendar month preceding the
month in which the interest payment being adjusted shall be due and payable.

Subject to the other provisions hereof, the principal on this Note is payable in
lawful  money of the  United  States  in  Fifty-Nine  (59)  consecutive  monthly
installments  of  Twenty-Five  Thousand  and 00/100  Dollars  ($25,000.00)  each
("Periodic Installment") and a final installment which shall be in the amount of
the total outstanding unpaid principal.  The first Periodic Installment shall be
due and payable on 7-15-94 and the following Periodic Installments and the final
installment  shall be due and payable on the same day of each succeeding  period
(each,  a "Payment  Date").  In addition to the payments of  principal  provided
above,  interest at the Contract Rate shall be payable on the Payment Date.  All
payments shall be applied first to interest and then to principal.  Each payment
may, at the option of the Payee, be calculated and applied on an assumption that
such  payment  would be made on its due  date.  The  acceptance  by Payee of any
payment  which is less than payment in full of all amounts due and owing at such
time shall not  constitute a waiver of Payee's right to receive  payment in full
at such time or at any prior or subsequent time. Interest shall be calculated on
the basis of a 365 day year (366 day leap year).

The Maker  hereby  expressly  authorizes  the Payee to insert  the date value is
actually  given  in the  blank  space  on the  face  hereof  and on all  related
documents pertaining hereto.

This Note may be secured  by a  security  agreement,  chattel  mortgage,  pledge
agreement or like instrument (each of which being hereinafter called a "Security
Agreement").

Time is of the essence  hereof.  If any  installment  or any other sum due under
this Note or any Security  Agreement is not received  within ten (10) days after
the  applicable  due date, the Maker agrees to pay, in addition to the amount of
each such  installment  or other sum, a late payment charge of five percent (5%)
of said  installment or other sum, but not exceeding any lawful maximum.  If (i)
Maker  fails to make  payment of any amount due  hereunder  within ten (10) days
after the same  becomes due and  payable;  or (ii) Maker is in default  under or
fails  to  perform  under  any  term  or  condition  contained  in any  Security
Agreement,  then the entire  principal sum remaining  unpaid,  together with all
interest  thereon  and any other sum  payable  under  this Note or the  Security
Agreement,  at the election of Payee,  shall immediately become due and payable,
with interest  thereon at the lesser of eighteen  percent {18%) per annum or the
highest rate not prohibited by applicable law from the date of such  accelerated
maturity until paid (both before and after any judgment).

The Maker may prepay in full, but not in part, its entire indebtedness hereunder
upon  payment  of  an  additional  sum  as a  premium  equal  to  the  following
percentages of the original principal balance for the indicated period:

Prior to the first annual anniversary date of this Note:    three percent   (3%)
Thereafter and prior to the second annual 
     anniversary date of this Note:                         two percent     (2%)
Thereafter and prior to the third annual
     anniversary date of this Note:                         one percent     (1%)
Thereafter and prior to the fourth annual 
     anniversary date of this Note:                         zero percent    (0%)
Thereafter and prior to the fifth annual 
     anniversary date of this Note:                         zero percent    (0%)

         and zero percent (0%) thereafter,  plus all other sums due hereunder or
under any Security Agreement.

It is the intention of the parties  hereto to comply with the  applicable  usury
laws;  accordingly,  it is agreed  that,  notwithstanding  any  provision to the
contrary in this Note or any Security Agreement,  in no event shall this Note or
any Security  Agreement require the payment or permit the collection of interest
in excess of the maximum amount  permitted by applicable law. If any such excess
interest is contracted for,  charged or received under this Note or any Security
Agreement,  or if all of the principal  balance shall be prepaid,  so that under
any of such  circumstances  the amount of interest  contracted  for,  charged or
received  under this Note or the  Security  Agreement on the  principal  balance
shall exceed the maximum amount of interest permitted by applicable law, then in
such event (a) the  provisions of this paragraph  shall govern and control,  (b)
neither  Maker nor any other  person or entity now or  hereafter  liable for the
payment  hereof  shall be  obligated  to pay the amount of such  interest to the
extent  that it is in excess of the  maximum  amount of  interest  permitted  by
applicable  law,  (c) any such  excess  which may have been  collected  shall be
either applied as a credit against the then unpaid principal balance or refunded
to Maker,  at the option of the Payee,  and (d) the  effective  rate of interest
shall be automatically reduced to the maximum lawful contract rate allowed under
applicable law as now or hereafter  construed by the courts having  jurisdiction
thereof.  It is further  agreed that without  limitation of the  foregoing,  all
calculations of the rate of interest  contracted for,  charged or received under
this  Note  or the  Security  Agreement  which  are  made  for  the  purpose  of
determining whether such rate exceeds the maximum lawful contract rate, shall be
made,  to the extent  permitted by  applicable  law, by  amortizing,  prorating,
allocating  and  spreading  in equal parts  during the period of the full stated
term of the indebtedness  evidenced hereby,  all interest at any time contracted
for,  charged or received  from Maker or otherwise by Payee in  connection  with
such indebtedness; provided, however, that if applicable state law is amended or
the law of the United States of America  preempts any  applicable  state law, so
that it becomes  lawful for the Payee to  receive a greater  interest  per annum
rate than is presently allowed,  the Maker agrees that, on the effective date of
such amendment or preemption,  as the case may be, the lawful maximum  hereunder
shall be increased to the maximum interest per annum rate allowed by the amended
state law or the law of the

United States of America.

The Maker and a1l  sureties,  endorsers,  guarantors  or any  others  (each such
person,  other than the Maker,  an "Obligor")  who may at any time become liable
for the payment  hereof  jointly  and  severally  consent  hereby to any and all
extensions of time, renewals, waivers or modifications of, and all substitutions
or releases of, security or of any party primarily or secondarily liable on this
Note or any Security Agreement or any term and provision of either, which may be
made,  granted or consented to by Payee,  and agree that suit may be brought and
maintained  against any one or more of them,  at the  election of Payee  without
joinder of any other as a party  thereto,  and that Payee  shall not be required
first to foreclose,  proceed against, or exhaust any security hereof in order to
enforce  payment  of  this  Note.  The  Maker  and  each  Obligor  hereby  waive
presentment,  demand  for  payment,  notice of  nonpayment,  protest,  notice of
protest,  notice of dishonor,  and all other notices in connection herewith,  as
well as filing of suit (if permitted by law) and  diligence in  collecting  this
Note or enforcing any of the security hereof,  and agree to pay (if permitted by
law) all expenses  incurred in collection,  including  Payee's actual attorneys'
fees.  Maker and each  Obligor  agree that fees not in excess of twenty  percent
(20%) of the amount then due shall be deemed reasonable.

THE MAKER HEREBY  UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF,  DIRECTLY OR  INDIRECTLY,  THIS
NOTE,  ANY OF THE  RELATED  DOCUMENTS,  ANY  DEALINGS  BETWEEN  MAKER  AND PAYEE
RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED  TRANSACTIONS,
AND/OR THE RELATIONSHIP THAT IS BEING  ESTABLISHED  BETWEEN MAKER AND PAYEE. THE
SCOPE OF THIS WAIVER IS INTENDED TO BE ALL  ENCOMPASSING OF ANY AND ALL DISPUTES
THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION,  CONTRACT CLAIMS,
TORT  CLAIMS,  BREACH OF DUTY  CLAIMS,  AND ALL OTHER  COMMON LAW AND  STATUTORY
CLAIMS.) THIS WAIVER IS IRREVOCABLE  MEANING THAT IT MAY NOT BE MODIFIED  EITHER

CONSENT TO A TRIAL BY THE COURT.

This Note and any  Security  Agreement  constitute  the entire  agreement of the

     (a) Until the declaration of any default hereunder,  Debtor shall remain in
possession of the Collateral;  provided,  however, that Secured Party shall have
the right to possess (i) any chattel paper or instrument that constitutes a part
of the Collateral, and (ii) any other Collateral which because of its nature may
require  that  Secured  Party's  security   interest  therein  be  perfected  by
possession.  Secured Party,  its successors  and assigns,  and their  respective
agents, shall have the right to examine and inspect any of the Collateral at any
time during normal business hours.  Upon any request from Secured Party,  Debtor
shall  provide  Secured  Party with ??????  of the then current  location of the

     (d) Debtor sha11 pay promptly when due all taxes, license fees, assessments
and public and private charges levied or assessed on any of the  Collateral,  on
the use thereof, or on this Agreement or any of the other Debt Documents. At its
option,  Secured Party may discharge taxes,  liens,  security interests or other
encumbrances  at any time levied or placed on the Collateral and may pay for the
maintenance,   insurance  and  preservation  of  the  Collateral  or  to  effect
compliance  with the terms of this Agreement or any of the other Debt Documents.
Debtor  shall  reimburse  Secured  Party,  on demand,  for any and all costs and
expenses incurred by Secured Party in connection  therewith and agrees that such
reimbursement obligation sha11 be secured hereby.

     (e) Debtor shall, at all times,  keep accurate and complete  records of the
Collateral,  and Secured Party, its successors and assigns, and their respective
agents,  shall have the right to examine,  inspect and make extracts from all of
Debtor's books and records  relating to the Collateral at any time during normal
business hours.

     (f) If agreed by the parties,  Secured  Party may, but shall in no event be

Collateral  and  shall be  subject  to the  security  interest  granted  herein.
Additions to, reductions or exchanges of, or substitutions  for, the Collateral,
payments on account of any obligation or liability secured hereby,  increases in
the obligations and  liabilities  secured hereby,  or the creation of additional
obligations  and liabilities  secured  hereby,  may from time to time be made or
occur without  affecting the  provisions of this  Agreement or the provisions of
any obligation or liability which this Agreement secures.

     (g) Any third  person at any time and from time to time  holding all or any
portion of the Collateral shall be deemed to, and shall,  hold the Collateral as
the agent of, and as pledge holder for, Secured Party. At any time and from time
to time,  Secured  Party may give notice to any third person  holding all or any
portion of the  Collateral  that such third person is holding the  Collateral as
the agent of, and as pledge holder for, the Secured Party.

4.   INSURANCE.

     The  Collateral  shall at all times be held at  Debtor's  risk,  and Debtor
shall  keep it  insured  against  loss or damage by fire and  extended  coverage
perils, theft,  burglary,  and for any or all Collateral which are vehicles, for
risk of loss by  collision,  and where  requested by Secured Party against other
risks  as  required  thereby,  for the  full  replacement  value  thereof,  with
companies,  in amounts and under policies  acceptable to Secured  Party.  Debtor
shall,  if Secured  Party so  requires,  deliver to Secured  Party,  policies or
certificates  of  insurance  evidencing  such  coverage.  Each policy shall name
Secured  Party as loss payee  thereunder,  shall provide for coverage to Secured
Party regardless of the breach by Debtor of any warranty or representation  made
therein, shall not be subject to co-insurance, and shall provide for thirty (30)
days  written  notice  to  Secured  Party  of  the   cancellation   or  material
modification  thereof.  Debtor hereby appoints  Secured Party as its attorney in
fact to make proof of loss,  claim for insurance and adjustments  with insurers,
and to execute or endorse all  documents,  checks or drafts in  connection  with
payments made as a result of any such insurance policies.  Proceeds of insurance
shall be  applied,  at the option of  Secured  Party,  to repair or replace  the
Collateral or to reduce any of the Indebtedness secured hereby.

of the Collateral other than Permitted Liens.

     (b) Debtor  agrees to  furnish  its annual  financial  statements  and such
interim  statements as Secured Party may require in form satisfactory to Secured
Party. Any and all financial statements submitted and to be submitted to Secured
Party  have  and will  have  been  prepared  on a basis  of  generally  accepted
accounting  principles,  and are and will be  complete  and  correct  and fairly
present Debtor's financial  condition as at the date thereof.  Secured Party may
at any  reasonable  time examine the books and records of Debtor and make copies
thereof.

6.   FURTHER ASSURANCES.

     (a) Debtor shall,  upon request of Secured Party,  furnish to Secured Party
such further  information,  execute and deliver to Secured Party such  documents
and  instruments  (including,   without  limitation,   Uniform  Commercial  Code
financing statements) and do such other acts and things, as Secured Party may at
any time  reasonably  request  relating to the  perfection  or protection of the
security  interest  created by this Agreement or for the purpose of carrying out
the intent of this  Agreement.  Without  limiting  the  foregoing,  Debtor shall
cooperate  and do all acts deemed  necessary or  advisable  by Secured  Party to
continue in Secured Party a perfected first security interest in the Collateral,
and shall obtain and furnish to Secured  Party,  any  subordinations,  releases,
landlord,  lessor,  or mortgagee  waivers,  and similar documents as may be from
time to time requested by, and which are in form and substance  satisfactory to,

and  generally to act on behalf of Debtor to execute and file  applications  for
title,  transfers  of title,  financing  statements,  notices  of lien and other
documents  pertaining  to any or all of the  Collateral.  Debtor  shall,  if any
certificate of title be required or permitted by law for any of the  Collateral,
obtain such  certificate  showing the lien hereof with respect to the Collateral
and promptly deliver same to Secured Party.

     (c) Debtor shall indemnify and defend the Secured Party, its successors and
assigns,  and their  respective  directors,  officers  and  employees,  from and
against any and all claims,  actions and suits (including,  without  limitation,
related attorneys' fees) of any kind, nature or description  whatsoever arising,
directly or indirectly, in connection with any of the Collateral.

the Secured Party, (ii) with or without legal process,  enter any premises where
the Collateral may be and take  possession  and/or remove said  Collateral  from
said premises,  (iii) sell the Collateral at public or private sale, in whole or
in part, and have the right to bid and purchase at said sale,  and/or (iv) lease
or  otherwise  dispose  of all or  part  of the  Collateral,  applying  proceeds
therefrom to the  obligations  then in default.  If requested by Secured  Party,
Debtor shall  promptly  assemble the Collateral and make it available to Secured
Party  at a  place  to be  designated  by  Secured  Party  which  is  reasonably
convenient  to both  parties.  Secured  Party may also  render any or all of the
Collateral  unusable at the Debtor's premises and may dispose of such Collateral
on such premises  without  liability for rent or costs. Any notice which Secured
Party is required to give to Debtor  under the  Uniform  Commercial  Code of the
time and place of any public sale or the time after  which any  private  sale or
other  intended  disposition  of the Collateral is to be made shall be deemed to
constitute  reasonable  notice if such notice is given to the last known address
of Debtor at least five (5) days prior to such action.

     (c) Proceeds from any sale or lease or other  disposition shall be applied:
first to all costs of repossession,  storage, and disposition  including without
limitation attorneys',  appraisers', and auctioneers' fees; second, to discharge
the obligations then in default;  third, to discharge any other  Indebtedness of
Debtor to Secured  Party,  whether as obligor,  endorser,  guarantor,  surety or
indemnitor;  fourth, to expenses incurred in paying or settling liens and claims
against the  Collateral;  and lastly,  to Debtor,  if there  exists any surplus.
Debtor shall remain fully liable for any deficiency.

     (d) In the event this  Agreement,  any Note or any other Debt Documents are
placed in the hands of an attorney for  collection of money due or to become due
or to obtain  performance  of any  provision  hereof,  Debtor  agrees to pay all
reasonable  attorneys'  fees incurred by Secured Party,  and further agrees that
payment of such fees is secured  hereunder.  Debtor and Secured Party agree that
such fees to the extent not in excess of twenty  percent (20%) of subject amount
owing after default (if permitted by law, or such lesser sum as may otherwise be
permitted by law) shall be deemed reasonable.

     (e) Secured Party's rights and remedies  hereunder or otherwise arising are
cumulative and may be exercised singularly or concurrently.  Neither the failure
nor any delay on the part of the Secured  Party to exercise any right,  power or
privilege  hereunder shall operate as a waiver thereof,  nor shall any single or
partial exercise of any right,  power or privilege preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. Secured
Party  shall not be deemed to have waived any of its rights  hereunder  or under
any other agreement,  instrument or paper signed by Debtor unless such waiver be
in writing and signed by Secured  Party.  A waiver on any one occasion shall not
be  construed  as a bar to or  waiver  of any  right  or  remedy  on any  future
occasion.

     (f) DEBTOR HEREBY  UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF,  DIRECTLY OR  INDIRECTLY,
THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED
HEREBY,  ANY DEALINGS  BETWEEN  DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT
MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS,  AND/OR THE RELATIONSHIP
THAT IS BEING  ESTABLISHED  BETWEEN DEBTOR AND SECURED PARTY.  THE SCOPE OF THIS
WAIVER IS INTENDED TO BE ALL  ENCOMPASSING  OF ANY AND ALL DISPUTES  THAT MAY BE
FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS,  AND ALL OTHER  COMMON LAW AND  STATUTORY  CLAIMS).  THIS
WAIVER IS  IRREVOCABLE,  MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN
WRITING,  AND THE WAIVER  SHALL APPLY TO ANY  SUBSEQUENT  AMENDMENTS,  RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT,  ANY OTHER DEBT DOCUMENTS, OR TO
ANY OTHER  DOCUMENTS OR AGREEMENTS  RELATING TO THIS  TRANSACTION OR ANY RELATED
TRANSACTION.  IN THE  EVENT  OF  LITIGATION,  THIS  AGREEMENT  MAY BE FILED AS A
WRITTEN CONSENT TO A TRIAL BY THE COURT.

<PAGE>

     (a) This Agreement,  any Note and/or any of the other Debt Documents may be
assigned,  in whole or in part, by Secured Party without  notice to Debtor,  and
Debtor  hereby waives any defense,  counterclaim  or  cross-complaint  by Debtor
against any assignee,  agreeing  that Secured Party shall be solely  responsible
therefor.

     (b) All notices to be given in connection  with this Agreement  shall be in
writing,  shall be addressed to the parties at their  respective  addresses  set
forth  hereinabove  (unless and until a different  address may be specified in a
written notice to the other party), and shall be deemed given (i) on the date of
receipt if  delivered  in hand or by  facsimile  transmission,  (ii) on the next
business day after being sent by express mail, and (iii) on the fourth  business
day after being sent by regular,  registered or certified  mail. As used herein,
the term  "business  day" shall mean and include  any day other than  Saturdays,
Sundays,  or other  days on which  commercial  banks in New  York,  New York are
required or authorized to be closed.

     (c) Secured  Party may correct  patent errors herein and fill in all blanks
herein  or in any  Collateral  Schedule  consistent  with the  agreement  of the
parties.

     (d) Time is of the essence hereof. This Agreement shall be binding, jointly
and severally,  upon all parties  described as the "Debtor" and their respective
heirs,  executors,  representatives,  successors and assigns, and shall inure to
the benefit of Secured Party, its successors and assigns.

     (e) This  Agreement  and its  Collateral  Schedules  constitute  the entire
agreement  between the parties  with  respect to the subject  matter  hereof and
supercede all prior  understandings  (whether  written,  verbal or implied) with
respect  thereto.  This  Agreement  and its  Collateral  Schedules  shall not be
changed  or  terminated  orally or by course of  conduct,  but only by a writing
signed by both parties hereto. Section headings contained in this Agreement have
been included for  convenience  only, and shall not affect the  construction  or
interpretation hereof.

     (t) This Agreement shall continue in full force and effect until all of the
Indebtedness has been indefeasibly paid in full to Secured Party. The surrender,
upon payment or otherwise,  of any Note or any of the other documents evidencing
any of the  Indebtedness  shall not affect the right of Secured  Party to retain
the  Collateral  for such other  Indebtedness  as may then exist or as it may be
reasonably   contemplated  will  exist  in  the  future.  This  Agreement  shall
automatically  be reinstated in the event that Secured Party is ever required to
return or restore the payment of all or any portion of the Indebtedness  (all as
though such payment had never been made).

     IN WITNESS WHEREOF, Debtor and Secured Party, intending to be legally bound
hereby,  have duly executed this Agreement in one or more counterparts,  each of
which shall be deemed to be an original, as of the day and year first aforesaid.

GE  Capital  Credit  Documents  or the  MCRC  Credit  Documents,  in  each  case
concurrently with the giving of such notice to Borrower; provided, however, that

                                    12-28-95
                                    --------

          -------------------------------------------------------------
                               (Address of Maker)

FOR VALUE  RECEIVED,  Optical  Corporation  of America  dba OCA  Applied  Optics
("Maker") promises,  jointly and severally if more than one, to pay to the order
of General Electric Capital Corporation or any subsequent holder hereof (each, a
"Payee") at its office located at 7700 Irvine Center Drive Suite 400, Irvine, CA
92718 or at such other place as Payee or the holder  hereof may  designate,  the
principal sum of Two Hundred Three Thousand Nine Hundred Eighty-Seven and 63/100
Dollars  ($203,987.63),  with interest on the unpaid principal balance, from the
date hereof  through and  including  the dates of  payment,  at a fixed,  simple
interest rate of Nine and Ninety-Three  Hundredths percent (9.93%) per annum, to
be paid in lawful money of the United States, in Sixty (60) consecutive  monthly
installments of principal and interest of Four Thousand Two Hundred  Seventy-Two
and  29/100  Dollars  ($4,872.29)  each  ("Periodic  Intallment")  and  a  final
installment which shall be in the amount of the total outstanding  principal and
interest. The first Periodic Installment shall be due and payable on 1-28-96 and
the following  Periodic  Installments and the final installment shall be due and
payable on the same day of each succeeding period (each, a "Payment Date").

All  payments  shall be applied  first to interest  and then to  principal.  The
acceptance  by Payee of any  payment  which is less than  payment in full of all
amounts  due and owing at such time  shall not  constitute  a waiver of  Payee's
right to  receive  payment  in full at such time or at any  prior or  subsequent
time.  Interest shall be calculated on the basis of a 365 day year (366 day leap
year). The payment of any Periodic  Installment  after its due date shall result
in a corresponding  decrease in the portion of the Periodic Installment credited
to  the  remaining  unpaid  principal  balance.  The  payment  of  any  Periodic
Installment  prior to its due date shall result in a  corresponding  increase in
the  portion  of the  Periodic  Installment  credited  to the  remaining  unpaid
principal balance.

The Maker  hereby  expressly  authorizes  the Payee to insert  the date value is
actually  given  in the  blank  space  on the  face  hereof  and on all  related
documents pertaining hereto.

This Note may be secured  by a  security  agreement,  chattel  mortgage,  pledge
agreement or like  instrument  (each of which is hereinafter  called a "Security
Agreement.")

Time is of the essence  hereof.  If any  installment  or any other sum due under
this Note or any Security  Agreement is not received  within ten (10) days after
its due date,  the Maker  agrees to pay,  in addition to the amount of each such
installment  or other sum, a late  payment  charge of five  percent  (5%) of the
amount of said  installment or other sum, but not exceeding any lawful  maximum.
If (i) Maker fails to make payment of any amount due hereunder  within (10) days
after the same becomes due and payable; or (ii) Maker is in default, or fails to
perform,  under any term or condition contained in any Security Agreement,  then
the entire  principal sum remaining  unpaid,  together with all accrued interest
thereon and any other sum payable under this Note or any Security Agreement,  at
the election of Payee, shall immediately  become due and payable,  with interest
thereon at the lesser of eighteen  percent  (18%) per annum or the highest  rate
not  prohibited by  applicable  law from the date of such  accelerated  maturity
until paid (both before and after any judgment).

<TABLE>

The Maker may prepay in full, but not in part, its entire indebtedness hereunder
upon  payment  of  an  additional  sum  as a  premium  equal  to  the  following
percentages of the original principal balance for the indicated period:

<S>                                                                               <C>                    <C> 
Prior to the first annual anniversary date of this Note:                          three percent          (3%)
Thereafter and prior to the second annual anniversary date of this Note:          two percent            (2%)
Thereafter and prior to the third annual anniversary date of this Note:           one percent            (1%)
Thereafter and prior to the fourth annual anniversary date of this Note:          zero percent           (0%)
Thereafter and prior to the fifth annual anniversary date of this Note:           zero percent           (0%)

</TABLE>

     and zero  percent  (0%)  thereafter,  plus all other sums due  hereunder or
     under any Security Agreement.

It is the intention of the parties  hereto to comply with the  applicable  usary
laws;  accordingly,  it is agreed  that,  notwithstanding  any  provision to the
contrary in this Note or any Security Agreement,  in no event shall this Note or
any Security  Agreement require the payment or permit the collection of interest
in excess of the maximum amount  permitted by applicable law. If any such excess
interest is contracted for,  charged or received under this Note or any Security
Agreement,  or if all of the principal  balance shall be prepaid,  so that under
any of such  circumstances  the amount of interest  contracted  for,  charged or
received  under this Note or any  Security  Agreement on the  principal  balance
shall exceed the maximum amount of interest permitted by applicable law, then in
such event (a) the  provisions of this paragraph  shall govern and control,  (b)
neither  Maker nor any other  person or entity now or  hereafter  liable for the
payment  hereof  shall be  obligated  to pay the amount of such  interest to the
extent  that it is in excess of the  maximum  amount of  interest  permitted  by
applicable  law,  (c) any such  excess  which may have been  collected  shall be
either applied as a credit against the then unpaid principal balance or refunded
to Maker,  at the option of the Payee,  and (d) the  effective  rate of interest
shall be automatically reduced to the maximum lawful contract rate allowed under
applicable law as now or hereafter  construed by the courts having  jurisdiction
thereof.  It is further  agreed that without  limitation of the  foregoing,  all
calculations of the rate of interest  contracted for,  charged or received under
this  Note  or any  Security  Agreement  which  are  made  for  the  purpose  of
determining whether such rate exceeds the maximum lawful contract rate, shall be
made,  to the extent  permitted by  applicable  law, by  amortizing,  prorating,
allocating  and  spreading  in equal parts  during the period of the full stated
term of the indebtedness  evidenced hereby,  all interest at any time contracted
for,  charged or received  from Maker or otherwise by Payee in  connection  with
such  indebtedness;  provided,  however,  that if any  appiicable  state  law is
amended or the law of the United Status of America preempts any applicable state
law, so that it becomes  lawful for the Payee to receive a greater  interest per
annum rate than is presently  allowed,  the Maker agrees that,  on the effective
date of such  amendment or  preemption,  as the case may be, the lawful  maximum
hereunder  shall be increased to the maximum  interest per annum rate allowed by
the amended state law or the law of the United States of America.

The Maker and all  sureties,  endorsers,  guarantors  or any  others  (each such
person, other than the Maker, an "Obligor") who may at any time become liable or
the  payment  hereof  jointly  and  severally  consent  hereby  to any  and  all
extensions of time, renewals, waivers or modifications of, and all substitutions
or releases of,  security or of any party,  primarily or  secondarily  liable on
this Note or any Security  Agreement or any term and provision of either,  which
may be made,  granted  or  consented  to by Payee,  and  agree  that suit may be
brought and maintained against any one or more of them, at the election of Payee
without  joinder of any other as a party  thereto,  and that Payee  shall not be
required first to foreclose,  proceed against, or exhaust any security hereof in
order to enforce  payment of this Note. The Maker and each Obligor hereby waives
presentment,  demand  for  payment,  notice of  nonpayment,  protest,  notice of
protest,  notice of dishonor and all other  notices in connection  herewith,  as
well as filing of suit (if permitted by law} and diligence in collecting


<PAGE>

this  Note or  enforcing  any of the  security  hereof,  and  agrees  to pay (if
permitted by law) all expenses incurred in collection,  including Payee's actual
attorneys' fees. Maker and each Obligor agrees that fees not in excess of twenty
percent (20%) of the amount then due shall be deemed reasonable.

THE MAKER HEREBY  UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF,  DIRECTLY OR  INDIRECTLY,  THIS
NOTE,  ANY OF THE  RELATED  DOCUMENTS,  ANY  DEALINGS  BETWEEN  MAKER  AND PAYEE
RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED  TRANSACTIONS,
AND/OR THE RELATIONSHIP THAT IS BEING  ESTABLISHED  BETWEEN MAKER AND PAYEE. THE
SCOPE OF THIS WAIVER IS INTENDED TO BE ALL  ENCOMPASSING OF ANY AND ALL DISPUTES
THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION,  CONTRACT CLAIMS,
TORT  CLAIMS,  BREACH OF DUTY  CLAIMS,  AND ALL OTHER  COMMON LAW AND  STATUTORY
CLAIMS.) THIS WAIVER IS IRREVOCABLE  MEANING THAT IT MAY NOT BE MODIFIED  EITHER
ORALLY OR IN WRITING,  AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT  AMENDMENTS,
RENEWALS,  SUPPLEMENTS OR MODIFICATIONS TO THIS NOTE, ANY RELATED DOCUMENTS,  OR
TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED
TRANSACTION.  IN THE  EVENT OF  LITIGATION,  THIS NOTE MAY BE FILED AS A WRITTEN
CONSENT TO A TRIAL BY THE COURT.

This Note and any  Security  Agreement  constitute  the entire  agreement of the
Maker and Payee with respect to the subject  matter  hereof and  supercedes  all
prior understandings, agreements and representations, express or implied.

No  variation  or  modification  of  this  Note,  or  any  waiver  of any of its
provisions  or  conditions,  shall be valid  unless in writing  and signed by an
authorized  representative  of  Maker  and  Payee.  Any  such  waiver,  consent,
modification or change shall be effective only in the specific  instance and for
the specific purpose given.

Any provision in this Note or any Security  Agreement  which is in conflict with
any statute, law or applicable rule shall be deemed omitted, modified or altered
to conform thereto.

                  CROSS-COLLATERAL AND CROSS-DEFAULT AGREEMENT

General Electric Capital Corporation
7700 Irvine Center Drive Suite 400
Irvine, CA 92718

Gentlemen:

     You have entered into or purchased one or more  conditional sale contracts,
lease agreements, chattel mortgages, security agreements, notes and other choses
in action  (herein  designated  "Accounts")  arising  from the bona fide sale or
lease to us, by various vendors or lessors, of equipment and inventory,  (herein
designated  "Collateral")  and/or  you have made  direct  loans to or  otherwise
extended credit to us evidenced by interests in Collateral.

     In  order to  induce  you to  extend  our  time of  payment  on one or more
Accounts  and/or to make  additional  loans to us and/or to purchase  additional
Accounts and/or to lease us additional equipment, and in consideration of you so
doing,  and for other good and valuable  consideration,  the receipt of which we
hereby acknowledge, we agree as follows:

     All presently existing and hereafter acquired  Collateral in which you have
or shall have a security  interest  shall secure the payment and  performance of
all of our  liabilities  and  obligations  to you of every  kind and  character,
whether joint or several, direct or indirect,  absolute or contingent, due or to
become due, and whether under presently  existing or hereafter  created Accounts
or agreements, or otherwise.

     We further agree that your security interest in the property covered by any
Account now held or hereafter  acquired by you shall not be  terminated in whole
or in part until and unless all  indebtedness  of every  kind,  due or to become
due,  owed by us to you is  fully  paid  and  satisfied  and the  terms of every
Account have been fully  performed  by us. It is further  agreed that you are to
retain your  security  interest in all property  covered by all Accounts held or
acquired  by you,  as  security  for  payment  and  performance  under each such
Account,  notwithstanding  the fact that one or more of such Accounts may become
fully paid.

     This  instrument  is intended to create  cross-default  and  cross-security
between  and among all the  within  described  Accounts  now owned or  hereafter
acquired by you.

     A default  under any Account or  agreement  shall be deemed to be a default
under all other  Accounts and  agreements.  A default shall result if we fail to
pay any sum when due on any  Account  or  agreement,  or if we breach any of the
other  terms and  conditions  thereof,  or if we become  insolvent,  cease to do
business as a going concern, make an assignment for the benefit of creditors, or
if a petition for a receiver or in  bankruptcy  is filed by or against us, or if
any of our property is seized,  attached or levied upon. Upon our default any or
all Accounts and agreements  shall, at your option,  become  immediately due and
payable without notice or demand to us or any other party obligated thereon, and
you shall have and may  exercise  any and all rights and  remedies  of a secured
party  under  the  Uniform   Commercial   Code  as  enacted  in  the  applicable
jurisdiction  and as  otherwise  granted  to you  under  any  Account  or  other
agreement.  We hereby waive, to the maximum extent  permitted by law, notices of
default,  notices of repossession  and sale or other  disposition of collateral,
and all other  notices,  and in the event any such notice  cannot be waived,  we
agree that if such notice is mailed to us postage  prepaid at the address  shown
below at least five (5) days prior to the  exercise by you of any of your rights
or  remedies,  such  notice  shall be deemed to be  reasonable  and shall  fully
satisfy any requirement for giving notice.

     All  rights   granted  to  you  hereunder   sha11  be  cumulative  and  not
alternative,  shall be in  addition  to and shall in no manner  impair or affect
your rights and remedies under any existing Account, agreement,  statute or role
of law.

     This  agreement  may not be varied or  altered  nor its  provisions  waived
except by your duly executed  written  agreement.  This agreement shall inure to
the benefit of your  successors and assigns and shall be binding upon our heirs,
administrators, executors, legal representatives, successors and assigns.

     IN WITNESS  WHEREOF,  this agreement is executed this 28th day of December,
1995.

                           PROMISSORY NOTE

DATE: February 1, 1994

FOR  VALUE  RECEIVED,  the  undersigned,   OPTICAL  CORPORATION  OF  AMERICA,  a
corporation  organized  and  existing  under  the  laws of the  Commonwealth  of
Massachusetts,  with its principal place of business in Garden Grove, California
(herein  called  "Maker")  promises  to  pay to the  order  of the  Perkin-Elmer
Corporation,  a New York Corporation with its principal place of business at 761
Main Street, Norwalk,  Connecticut (the "Corporation"),  at such place, or other
place as may be designated in writing by the holder of this Note,  the principal
sum  of  Four  Hundred  Thousand  Dollars  ($400,000),   plus  interest  on  the
outstanding  principal  balance  at the rate of ten  percent  (10%)  per  annum.
Payments of interest are due quarterly and shall commence on May 1, 1994, and be
payable  on the first day of  August,  November,  February  and May in each year
thereafter in accordance with Payment  Schedule I attached  hereto.  Payments of
principal are due in five (5) quarterly  installments of Eighty Thousand Dollars
($80,000)  commencing on February 1, 1996, and on the first day May, August, and
November  1996,  with a final  payment on  February 1, 1997 in  accordance  with
Payment Schedule I attached hereto.

Should Maker default in any obligation  under this Note, the holder of this Note
at its option may,  without  giving  notice to the Maker,  in  additional to all
other remedies,  declare the whole sum of unpaid  principal and accrued interest
to be due and payable,  and  thereafter  the whole sum of unpaid  principal  and
accrued interest shall forthwith become due and payable.

The Maker waives demand,  presentment for payment,  notice of dishonor,  protest
and notice of  protest;  waives any and all lack of  diligence  or delays in the
collection or enforcement  hereof;  and consents that the time of payment may be
extended or this Note may be renewed without notice,  and without  releasing the
undersigned.

In event  that any action  shall be  instituted  on this Note,  or any action or
proceeding is taken with respect to a default hereunder,  the prevailing part in
any such action or  proceeding  shall be paid by the other party all expenses in
connection therewith, including reasonable attorneys' fees.

<PAGE>

This Note shall be governed by and be construed in  accordance  with the laws of
the State of Connecticut.

No course of dealing  between the Maker and the holder of this Note and no delay
on the part of the holder of this Note in exercising any rights of the holder of
this Note  shall  operate  as a waiver of the rights of the holder of this Note;
nor shall any delay,  unless agreed to in writing by the Maker and the holder of
this Note, constitute a forbearance. No covenant or other provision of this Note
nor any default may be waived otherwise than by a written  instrument  signed by
the party so waiving  such  covenant or other  provisions  or default;  provided
however,  that no such  waiver  shall  extend to or impair  any  obligation  not
expressly  waived,  or impair any right  consequent  thereon.  Any waiver may be
given subject to satisfaction of conditions stated therein.

Any other provisions  herein or in any other agreement between the holder hereof
and Maker to the contrary notwithstanding,  in no event shall the amount paid or
agreed to be paid as interest  exceed the highest  lawful rate,  then the latter
shall be the applicable interest under this Note.

The Maker hereby waives all fights of set-off and  counterclaim  with respect to
this Note including rights of set-off and counterclaim with respect to this Note
which may arise from claims heretofore unknown to the Maker.

IN WITNESS WHEREOF,  this Note has been duly executed bv Maker as of the day and
year first above written.

Massachusetts Capital Resource Company
420 Boylston Street
Boston, Massachusetts 02116

Re:  Subordinated Notes due 1999 and
     Common Stock Purchase Warrants

Gentlemen:

     Optical   Corporation  of  America,   a  Massachusetts   corporation   (the
"Company"),  hereby  agrees with  Massachusetts  Capital  Resource  Company (the
"Purchaser") as follows:

                                    ARTICLE I

                 PURCHASE, SALE AND TERMS OF NOTES AND WARRANTS

     1.01.  The Notes.  The Company has  authorized the issuance and sale to the
Purchaser  of the  Company's  Subordinated  Notes,  due  June 30,  1999,  in the
original  principal  amount  of  $1,500,000.  The  Subordinated  Notes  shall be
substantially  in the form set  forth in  Exhibit  1.01  hereto  and are  herein
referred to  individually  as a "Note" and  collectively  as the "Notes",  which
terms  shall  also  include  any notes  delivered  in  exchange  or  replacement
therefor.

     1.02.  The Warrants. The Company has also  authorized the issuance and sale
to the  Purchaser  of the  Company's  Common  Stock  Purchase  Warrants  for the
purchase  (subject to  adjustment  as provided  therein) of 76,000 shares of the
Company's   Common  Stock.   The  Common  Stock   Purchase   Warrants  shall  be
substantially  in the form set  forth in  Exhibit  1.02  hereto  and are  herein
referred to  individually  as a "Warrant" and  collectively  as the  "Warrants",
which terms shall also include any warrants delivered in exchange or replacement
therefor.

     1.03.  Purchase and Sale of Notes and Warrants.

            (a) The  Closing.  The  Company  agrees  to  issue  and  sell to the
Purchaser, and, subject to and in reliance upon the representations, warranties,
terms and  conditions of this  Agreement,  the Purchaser  agrees to purchase the
Notes and the Warrants  for an  aggregate  purchase  price of  $1,500,000.  Such
purchase and sale shall take place at a closing (the "Closing") to


<PAGE>

                                      -2-

be held at the office of Messrs. Testa, Hurwitz & Thibeault,  Exchange Place, 53
State Street, Boston,  Massachusetts,  on May 28, 1992 at 2:00 P.M.,  or on such
other date and at such time as may be mutually  agreed upon.  At the Closing the
Company will initially issue one Note, payable to the order of the Purchaser, in
the principal  amount of $1,500,000  and one Warrant,  registered in the name of
the Purchaser,  to purchase  (subject to adjustment as provided  therein) 76,000
shares of the Company's Common Stock, against delivery to the Company of a check
or a receipt of a wire  transfer,  in the amount of $1,500,000 in payment of the
full purchase price for the Notes and Warrants.

            (b)  Allocation of Purchase  Price.  The Company and the  Purchaser,
having adverse interests and as a result of arm's length bargaining,  agree that
(i) neither the  Purchaser nor any of its partners has rendered or has agreed to
render any  services to the Company in  connection  with this  Agreement  or the
issuance of the Notes and  Warrants;  (ii) the  Warrants are not being issued as
compensation; and (iii) the assumed prices at which the Notes would be issued if
they were  issued  apart  from the  Warrants  are 100% of the  principal  amount
thereof.  The Company and the Purchaser recognize that this Agreement determines
the original  issue discount to be taken into account as such by the Company and
the  Purchaser  for federal  income tax  purposes on the Notes and they agree to
adhere to this Agreement for such purposes.

            (c) Use of  Proceeds.  The Company  agrees to use the full  proceeds
from the sale of the Notes and Warrants as working capital for its operations in
Massachusetts, including for the repayment of temporary financing obtained by it
with which to pay part of the purchase  price for its  acquisition  on March 31,
1992 of certain  assets of Contraves  USA,  Inc.  pursuant to that certain Asset
Purchase Agreement, dated January 31, 1992, as amended by Amendment No. 1, dated
March 31, 1992. Further,  the Company agrees that full proceeds from the sale of
the Notes and Warrants will be utilized for  purposes which increase or maintain
equal opportunity employment in the Commonwealth of Massachusetts.

     1.04.  Payments  and  Endorsements.  Payments  of  principal,  interest and
premium,  if any, on the Notes,  shall be made  directly by check duly mailed or
delivered to the  Purchaser  at its address  referred to in Section 8.03 hereof,
without  any  presentment  or  notation  of  payment,  except  that prior to any
transfer of any Note,  the holder of record shall  endorse on such Note a record
of the date to which  interest has been paid and all payments made on account of
principal of such Note.

     1.05.  Redemptions.

            (a) Required Redemptions.  Beginning on and with September 30, 1994,
and on the  last  day of  December,  March,  June  and  September  in each  year
thereafter through and including June 30, 1999, the Company will redeem, without
premium,  $75,000 in principal amount of the Notes, or such lesser amount as may
be

                                      -3-

then outstanding,  together with all accrued and unpaid interest then due on the
amount so redeemed.  On  the stated or  accelerated  maturity of the Notes,  the
Company will pay the  principal  amount of the Notes then  outstanding  together
with all accrued and unpaid interest then due thereon. No optional redemption of
less than all of the Notes shall  affect the  obligation  of the Company to make
the redemptions required by this subsection.

            (b)  Optional  Redemptions  Without  Premium.  In  addition  to  the
redemptions  of the Notes required under  subsection  1.05(a),  on each required
redemption  date with  respect to the Notes,  the Company  may also  voluntarily
redeem,  together  with all accrued and unpaid  interest  then due thereon,  but
without premium,  an additional  principal amount of the Notes not to exceed the
amount of the required  redemption due on such date. This right of redemption of
the Notes under this subsection 1.05(b) shall not be cumulative.

            (c)  Optional  Redemptions  With  Premium.  Except  as  provided  in
subsections  1.05(a)  and (b) and in  addition  thereto,  the Company may at any
time, on or after July 1, 1992, (no optional redemption being permitted prior to
said  date)  redeem  the  Notes in whole or in part (in  integral  multiples  of
$10,000)  together with interest due on the amount so redeemed  through the date
of redemption, and a premium equal to the percentage of the principal  amount of
the Notes redeemed under this  subsection  applicable to the twelve month period
in which such redemption is made, as follows:

          12-month period
              ending                       Premium
          ---------------                  -------
          June 30, 1993                      11%
          June 30, 1994                       9%
          June 30, 1995                       7%
          June 30, 1996                       5%
          June 30, 1997                       3%
          June 30, 1998                       2%
          June 30, 1999                       0%

            (d)  Notice  of  Redemptions;  Pro rata  Redemptions.  Notice of any
optional  redemptions  pursuant to subsections 1.05(b) or  (c) shall be given to
all registered holders of the Notes at least ten (10) business days prior to the
date of such  redemption.  Each  redemption  of Notes  pursuant  to  subsections
1.05(a),  (b) or (c)  shall be made so that the Notes  then held by each  holder
shall be redeemed in a principal  amount  which shall bear the same ratio to the
total principal  amount of Notes being redeemed as the principal amount of Notes
then held by such holder bears to the  aggregate  principal  amount of the Notes
then outstanding.

     1.06.  Payment on  Non-Business  Days.  Whenever  any  payment to  be  made
shall be due on a  Saturday,  Sunday or a public holiday



<PAGE>


                                       -4-

under the laws of the Commonwealth of Massachusetts, such payment may be made on
the next succeeding business day, and such extension of  time shall in such case
be included in the computation of payment of interest due.

     1.07. Registration, etc. The Company shall maintain at its principal offlce
a register of the Notes and shall record  therein the names and addresses of the
registered holders of the Notes, the address to which notices are to be sent and
the address to which  payments are to be made as  designated  by the  registered
holder if other  than the  address of the  holder,  and the  particulars  of all
transfers,  exchanges and  replacements of Notes. No transfer of a Note shall be
valid unless made on such register for the registered holder or his executors or
administrators or his or their duly appointed attorney,  upon surrender therefor
for exchange as hereinafter  provided,  accompanied by an instrument in writing,
in form and execution reasonably  satisfactory to the Company.  Each Note issued
hereunder,  whether  originally or upon  transfer,  exchange or replacement of a
Note or Notes,  shall be  registered  on the date of  execution  thereof  by the
Company  and  shall be dated  the date to which  interest  has been paid on such
Notes or Note.  The  registered  holder of a Note shall be that  Person in whose
name the Note has been so registered by the Company.  A registered  holder shall
be deemed the owner of a Note for all purposes of this Agreement and, subject to
the provisions hereof, shall be entitled to the principal,  premium, if any, and
interest  evidenced  by such Note free from all  equities or rights of setoff or
counterclaim between the Company and the transferor of such registered holder or
any previous registered holder of such Note.

     1.08.  Transfer and Exchange of Notes. The registered holder of any Note or
Notes may, prior to maturity or prepayment thereof, surrender such Note or Notes
at the  principal  office of the Company  for  transfer  or  exchange.  Within a
reasonable  time after  notice to the Company  from a  registered  holder of its
intention to make such exchange and without  expense (other than transfer taxes,
if any) to such registered  holder, the Company shall issue in exchange therefor
another Note or Note,  in such  denominations  as  requested  by the  registered
holder,  for the same aggregate  principal amount as the unpaid principal amount
of the Note or Notes so  surrendered,  and having the same  maturity and rate of
interest,  containing  the same  provisions  and  subject  to the same terms and
conditions  as the  Note or Notes so  surrendered.  Each new Note  shall be made
payable to such Person or Persons,  or  registered  assigns,  as the  registered
holder of such  surrendered  Note or Notes may  designate,  and such transfer or
exchange  shall be made in such a manner  that no gain or loss of  principal  or
interest shall result therefrom.

     1.09.  Replacement of Notes.  Upon receipt of evidence  satisfactory to the
Company  of the loss,  theft,  destruction  or  mutilation  of any Note and,  if
requested in the case of any such loss,  theft or destruction,  upon delivery of
an indemnity bond or

<PAGE>

                                       -5-

other agreement or security reasonably  satisfactory to the Company,  or, in the
case of any such  mutilation,  upon surrender and cancellation of such Note, the
Company  will  issue a new Note,  of like tenor and amount and dated the date to
which  interest  has been  paid,  in lieu of such  lost,  stolen,  destroyed  or
mutilated Note;  provided,  however, if any Note of which Massachusetts  Capital
Resource Company,  its nominee,  or any of its partners is the registered holder
is lost, stolen or destroyed,  the affidavit of the President,  Treasurer or any
Assistant  Treasurer of the registered  holder  setting forth the  circumstances
with  respect  to  such  loss,  theft  or  destruction   shall  be  accepted  as
satisfactory  evidence thereof,  and no  indemnification  bond or other security
shall be required as a condition to the execution and delivery by the Company of
a new Note in replacement of such lost,  stolen or destroyed Note other than the
registered holder's written agreement to indemnify the Company.

     1.10.  Subordination.  The Company, for itself, its successors and assigns,
covenants and agrees,  and the Purchaser and each successor  holder of the Notes
by  his  or  its  acceptance  thereof,   likewise  covenants  and  agrees,  that
notwithstanding  any other provision of this Agreement or the Notes, the payment
of the  principal  of and  interest  on  each  and  all of the  Notes  shall  be
subordinated  in right of payment,  to the extent and in the manner  hereinafter
set  forth,  to the prior  payment in full of all  Senior  Debt (as  hereinafter
defined) at any time  outstanding.  The  provisions  of this  Section 1.10 shall
constitute a continuing representation to all Persons who, in reliance upon such
provisions,  become the holders of or continue  to hold  Senior  Debt,  and such
provisions  are made for the  benefit of the  holders of Senior  Debt,  and such
holders are hereby made obligees hereunder  to the same extent as if their names
were written herein as such, and they or any of them may proceed to enforce such
provisions  against the  Company or against  the holder of any Note  without the
necessity of joining the Company as a party.

            (a)  Payment  of  Senior  Debt.  In the event of any  insolvency  or
bankruptcy  proceedings,  or any  receivership,  liquidation,  reorganization or
other similar proceedings in connection therewith, relative to the Company or to
its property,  or, in the event of any  proceedings  for voluntary  liquidation,
dissolution or other winding up of the Company or distribution or marshalling of
its assets or any  composition  with  creditors of the  Company,  whether or not
involving  insolvency or bankruptcy,  then and in any such event all Senior Debt
shall be paid in full  before any  payment  or  distribution  of any  character,
whether in cash,  securities or other property,  shall be made on account of the
Notes;  and any such  payment  or  distribution,  except  securities  which  are
subordinate  and junior in right of payment  to the  payment of all Senior  Debt
then outstanding in terms of substantially  the same tenor as this Section 1.10,
which would, but for the provisions hereof, be payable or deliverable in respect
of the Notes shall be paid or  delivered  directly to the holders of Senior Debt
(or their duly authorized representatives),


<PAGE>

                                       -6-

in the proportions in which they hold the same, until all Senior Debt shall have
been paid in full,  and every  holder of the Notes by becoming a holder  thereof
shall,  by his or its  acceptance  thereof,  be  deemed to have  designated  and
appointed  the  holder or holders  of Senior  Debt (and  their  duly  authorized
representatives) as his or its agents and  attorneys-in-fact to demand, sue for,
collect and receive such Senior Debt holder's ratable share of all such payments
and  distributions and to file any necessary proof of claim therefor and to take
all  such  other  action  for and in the  name of the  holders  of the  Notes or
otherwise, as such Senior Debt holders (or their authorized representatives) may
determine to be necessary or  appropriate  for the  enforcement  of this Section
1.10.  The  Purchaser  and  each  successor  holder  of the  Notes by its or his
acceptance thereof agrees to execute,  at the request of the Company, a separate
agreement  with any holder of Senior Debt on the terms set forth in this Section
1.10,  and to take  all  such  other  action  as such  holder  or such  holder's
representative  may request in order to enable such holder to enforce all claims
upon or in respect of such holder's ratable share of the Notes.

                  (b) No Payment on Notes Under Certain Conditions. In the event
that any default  occurs in the payment of the  principal  of or interest on any
Senior Debt (whether as a result of the  acceleration  thereof by the holders of
such Senior Debt or otherwise) and during the  continuance of such default for a
period up to sixty (60) days and thereafter if judicial  proceedings  shall have
been instituted with respect to such defaulted payment, or (if a shorter period)
until such  payment  has been made or such  default  has been cured or waived in
writing by such  holder of Senior Debt then and during the  continuance  of such
event no payment of  principal  of or interest on the Notes shall be made by the
Company or accepted by any holder of the Notes who has received  written  notice
from the Company or from a holder of Senior Debt of such events.

                  (c)  Payments   Held  in  Trust.   In   case  any  payment  or
distribution  shall be paid or  delivered  to any holder of the Notes before all
Senior  Debt  shall  have  been  paid  in  full,  despite  or  in  violation  or
contravention of the terms of this  subordination,  such payment or distribution
shall be held in trust for and paid and  delivered  ratably  to the  holders  of
Senior Debt (or their duly  authorized  representatives),  until all Senior Debt
shall have been paid in full.

                  (d) Subrogation.  Subject to the payment in full of all Senior
Debt and until the Notes  shall be paid in full,  the holders of the Notes shall
be  subrogated  to the rights of the  holders  of Senior  Debt (to the extent of
payments  or  distributions  previously  made to such  holders  of  Senior  Debt
pursuant to the provisions of  subsections  (a) and (c) of this Section 1.10) to
receive  payments or  distributions  of assets of the Company  applicable to the
Senior Debt.  No such  payments or  distributions  applicable to the Senior Debt
shall,  as between  the  Company  and its  creditors,  other than the holders of
Senior Debt and the holders of the Notes, be deemed


<PAGE>


                                       -7-

to be a payment  by the  Company  to or on  account  of the  Notes;  and for the
purposes of such  subrogation,  no payments or  distributions  to the holders of
Senior Debt to which the  holders of the Notes would be entitled  except for the
provisions of this Section 1.10 shall, as between the Company and its creditors,
other than the holders of Senior Debt and the holders of the Notes, be deemed to
be a payment by the Company to or on account of the Senior Debt.

            (e)  Scope of  Section.  The  provisions  of this  Section  1.10 are
intended  solely for the purpose of defining the relative  rights of the holders
of the Notes,  on the one hand, and the holders of the Senior Debt, on the other
hand.  Nothing  contained in this Section 1.10 or elsewhere in this Agreement or
the Notes is intended to or shall impair, as between the Company,  its creditors
other  than the  holders of Senior  Debt,  and the  holders  of the  Notes,  the
obligation of the Company,  which is unconditional  and absolute,  to pay to the
holders of the Notes the  principal of and interest on the Notes as and when the
same shall become due and payable in accordance  with the terms  thereof,  or to
affect the  relative  rights of the  holders of the Notes and  creditors  of the
Company other than the holders of the Senior Debt, nor shall anything  herein or
therein  prevent the holder of any Note from  accepting any payment with respect
to such Note or exercising  all remedies  otherwise  permitted by applicable law
upon default under such Note,  subject to the rights, if any, under this Section
1.10 of the holders of Senior Debt in respect of cash, property or securities of
the Company received by the holders of the Notes.

            (f) Survival of Rights. The right of any present or future holder of
Senior Debt to enforce  subordination of the Notes pursuant to the provisions of
this Section 1.10 shall not at any time be  prejudiced or impaired by any act or
failure  to act on the part of the  Company or any such  holder of Senior  Debt,
including,  without limitation,  any forbearance,  waiver, consent,  compromise,
amendment, extension, renewal, acceptance or taking or release of security of or
in respect of any Senior Debt, or by noncompliance by the Company with the terms
of such  subordination  regardless of any knowledge thereof such holder may have
or otherwise be charged with.

            (g) Amendment or Waiver. The provisions of this Section 1.10 may not
be amended  or waived in any  manner  which is  detrimental  to any Senior  Debt
without the requisite  consent of the holders of all then  existing  Senior Debt
according to the applicable provisions thereof.

            (h) Senior Debt  Defined.  The term "Senior Debt" shall mean (i) all
Indebtedness of the Company for money borrowed from banks or other institutional
lenders,  including any extensions or renewals thereof,  whether  outstanding on
the date hereof or thereafter created or incurred,  which is not by its terms or
by separate  agreement  subordinate  and junior to or on a parity with the Notes
and which is permitted hereby at the time it is created


<PAGE>

                                      -8-

or incurred, and (ii) all guaranties by the Company which are not by their terms
or by separate agreement subordinate and junior to or on a parity with the Notes
and which are permitted hereby at the time they are made, of Indebtedness of any
Subsidiary  if such  Indebtedness  would have been Senior  Debt  pursuant to the
provisions  of  clause  (i) of this  sentence  had it been  Indebtedness  of the
Company. In making any loans which are (or the guaranties of which are) intended
to be Senior Debt,  the lenders or purchasers  thereof shall be entitled to rely
as to the fact that such  Indebtedness  or guaranty is  permitted  hereby upon a
certificate by the Company's  chief  financial  officer  purporting to show such
Indebtedness or guaranty will not result in the Company's failure to comply with
the  provisions  of  Article  IV  hereof in effect as of the date of the loan or
guarantee.

         1.11.  Representations by the Purchaser.  The Purchaser represents that
it is  acquiring  the Notes and  Warrants for its own account and that the Notes
and Warrants are being and will be acquired  for the purpose of  investment  and
not with a view to  distribution  or resale  thereof or of the  Common  Stock or
other  securities  receivable  upon  the  exercise  of  the  Warrants;  subject,
nevertheless,  to the  condition  that the  disposition  of the  property of the
Purchaser  shall at all times be within  its  control.  The  acquisition  by the
Purchaser of the Notes and  Warrants  shall  constitute a  confirmation  of this
representation.

         1.12.   Disclosure  of  Information  by  the  Purchaser.   The  Company
understands  that  the  Purchaser  is  a  special  purpose  limited  partnership
organized  under  Chapter  109 of  the  General  Laws  of  the  Commonwealth  of
Massachusetts  and  Chapter  816  of  the  Acts  and  Resolves  of  1977  of the
Commonwealth of Massachusetts (the "Capital Resource Company Act"), and as such,
in accordance with such  provisions,  the Purchaser,  in order to obtain certain
benefits for itself and its  partners,  is required to file certain  reports and
otherwise disclose information relating to the business,  financial affairs, and
future  prospects of the Company and its affiliates (as defined in the aforesaid
legislation)  with  the  Clerk  of the  Senate  and the  Clerk  of the  House of
Representatives of the General  Court of the Commonwealth of Massachusetts,  the
Secretary of Manpower Affairs,  the Commissioner of Insurance and the Department
of Revenue of the Commonwealth of Massachusetts, and that such reports and other
information may constitute  "public  records" within the purview of Section 7 of
Chapter 4 of the General Laws of the Commonwealth of Massachusetts. In addition,
information relating to the business,  financial affairs and future prospects of
the Company and its  affiliates  must be  disclosed to others in order to obtain
independent  confirmation  that  financing  on  substantially  similar  terms to
financing provided pursuant to this Agreement was not elsewhere available to the
Company.  The Company  hereby  authorizes  the  Purchaser  to disclose  all such
information relating to the business,  financial affairs and future prospects of
the Company and its affiliates as has been or may in the future be presented


<PAGE>

                                       -9-

to the  Purchaser  to all such  persons as the  Purchaser  in good  faith  deems
necessary or appropriate in order to fulfill its  obligations  under the Capital
Resource Company Act.

                                   ARTICLE II

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

     The Company represents and warrants as follows:

     3.01.  Organization  and  Standing.  The Company and OCA-AO are each a duly
organized and validly  existing  corporation  in good standing under the laws of
the jurisdiction in which it was organized and has all requisite corporate power
and authority  for  the ownership  and operation of its  properties  and for the
carrying  on of  its  business  as now  conducted  and  as  now  proposed  to be
conducted.  Neither  the  nature of the  business  conducted  by the  Company or
OCA-AO,  nor the  character of the  properties  owned or held under lease by the
Company or OCA-AO  requires the Company or OCA-AO to be qualified or licensed as
a  foreign  corporation  in any  state  or  jurisdiction.  OCA-AO  is  the  only
Subsidiary of the Company and all of its outstanding capital stock has been duly
authorized and validly  issued,  is fully paid and  nonassessable,  and is owned
beneficially  and of record by the  Company  free and clear of any lien,  right,
encumbrance or restriction of any nature,  including,  without  limitation,  any
lien,  right,  encumbrance  or  restriction  on transfer,  other than the pledge
thereof by the Company to Greyhound Financial  Corporation  pursuant to a Pledge
Agreement  dated as of March 23, 1990, a copy of which has been delivered to the
Purchaser.

     3.02. Corporate Action. The Company and OCA-AO have all necessary corporate
power and have taken all corporate action required to make all the provisions of
this Agreement, the Notes,

<PAGE>

                                      -11-

the Warrants,  the Guaranty and any other agreements and instruments executed in
connection  herewith and therewith the valid and  enforceable  obligations  they
purport to be.  Sufficient shares of authorized but unissued Common Stock of the
Company have been reserved by appropriate  corporate  action in connection  with
the prospective  exercise of the Warrants.  Neither the issuance of the Notes or
Warrants,  nor the  issuance of shares of Common  Stock upon the exercise of the
Warrants,  is subject to preemptive or other  similar  statutory or  contractual
rights and will not conflict with any  provisions of any agreement or instrument
to which the Company or OCA-AO is a party or by which it is bound.

     3.03. Governmental Approvals. No authorization, consent, approval, license,
exemption  of  or  filing  or  registration   with  any  court  or  governmental
department,  commission,  board, bureau, agency or instrumentality,  domestic or
foreign,  is or will  be  necessary  for,  or in  connection  with,  the  offer,
issuance,  sale,  execution or delivery by the Company and OCA-AO of, or for the
performance  by  either  of them of their  respective  obligations  under,  this
Agreement, the Notes, the Warrants or the Guaranty.

     3.04.  Litigation.  Except as is set forth on  Exhibit  3.04,  there is  no
litigation or governmental  proceeding or investigation  pending or, to the best
of the  knowledge  of the  Company,  threatened  against  the  Company or OCA-AO
affecting any of its  properties  or assets,  or against any Key Employee of the
Company or OCA-AO where such  litigation,  proceeding or  investigation,  either
individually  or in the aggregate,  would have a material  adverse effect on the
Company or OCA-AO,  nor, to the best of the knowledge of the Company,  has there
occurred  any event or does there exist any  condition on the basis of which any
litigation,  proceeding or investigation  might properly be instituted.  Neither
the Company nor OCA-AO,  nor, to the best of the  knowledge of the Company,  any
Key  Employee of the Company or OCA-AO is in default  with respect to any order,
writ, injunction, decree, ruling  or decision of any court, commission, board or
other government agency affecting the Company or OCA-AO. There are no actions or
proceedings  pending or threatened  (or any basis therefor known to the Company)
which might  result,  either in any case or in the  aggregate,  in any  material
adverse change in the business, operations, affairs or condition of the Company
or  OCA-AO or in any of its  properties  or  assets,  or which  might  call into
question  the  validity  of  this  Agreement,  the Notes,  the  Warrants  or the
Guaranty or any action taken or to be taken pursuant hereto or thereto.

     3.05. Compliance with Other Instruments.  The Company and OCA-AO each is in
compliance in all respects with the terms and  provisions of this  Agreement and
of its respective charter and bylaws and in all material respects with the terms
and  provisions  of the  mortgages,  indentures,  leases,  agreements  and other
instruments and of all judgments,  decrees, governmental orders, statutes, rules
and  regulations  by which it is bound or to which its  properties or assets are

Company or OCA-AO.  Neither the  execution and delivery of this  Agreement,  the
Notes,  the Warrants,  the Guaranty,  nor the  consummation of any  transactions

Company and OCA-AO  (including lease  obligations  required to be capitalized in
accordance  with  applicable  Statements of Financial  Accounting  Standards) is

trademark  rights,  trade names or trade name rights or franchises,  copyrights,
inventions and  intellectual  property rights being used to conduct its business
as now  operated  and as now  proposed  to be  operated;  and the conduct of its
business as now operated  and as now  proposed to be operated  does not and will
not  conflict  with valid  patents,  patent  rights,  licenses,  permits,  trade
secrets,  trademarks,  trademark  rights,  trade  names or trade name  rights or
franchises,  copyrights,  inventions and intellectual property rights of others.
Neither the Company nor OCA-AO has any  obligation to compensate  any Person for

period, nor of any basis for any such assessment or adjustment.

     3.10.  ERISA.  No employee  benefit plan  established or maintained,  or to
which  contributions have been made, by the Company or OCA-AO,  which is subject
to part 3 of Subtitle B of Title I of The Employee  Retirement  Income  Security

subcontract  or  otherwise)  to any other  contract,  agreement or grant of, any
federal or state governmental unit ("Government Contract"),  including,  without
limitation, any terms required pursuant to Federal Executive Order No. 11246 and

Company nor OCA-AO is presently, to the best of the Company's knowledge, subject
to any formal  proceedings  before,  or  investigations  by, such commissions or
governmental units.

     3.15.  Status of Notes and Warrants as Qualified  Investments.  The Company
has duly authorized the execution and delivery to the Purchaser on behalf of the
Company of the certificate  attached as Exhibit 3.15 hereto,  setting forth such
statements,  information  and  related  data  as are  necessary  to  permit  the
Purchaser  to  determine  and  demonstrate  that the Notes and  Warrants  issued

meaning of that term as set forth in the Capital  Resource  Company Act and that
the full proceeds of the Notes and Warrants will be used for purposes which will

counsel  by or on  behalf  of the  Company  or  OCA-AO  in  connection  with the
transactions  contemplated  hereby  contains any untrue  statement of a material

<PAGE>

                                      -16-

herein or in  writing  by the  Company  to the  Purchaser  and which  materially
adversely affects,  or in the future in the Company's opinion may, insofar as it
can now foresee, materially adversely affect the business, properties, assets or
condition,  financial or otherwise,  of the Company or OCA-AO.  Without limiting
the  foregoing,  the  Company  has no  knowledge  that there  exists any patent,
invention,   device,  application  or  principle  or  any  statute,  rule,  law,
regulation,  standard  or code  which  would  materially  adversely  affect  the
condition, financial or otherwise, or the operations of the Company or OCA-AO.

     3.18. No Brokers or Finders. No Person has or will have, as a result of the
transactions  contemplated by this Agreement, any right, interest or valid claim
against  or upon  the  Company  or  OCA-AO  for  any  commission,  fee or  other
compensation as a finder or broker because of any act or omission by the Company
or OCA-AO or any agent of the Company or OCA-AO.

     3.19.  Other  Agreements of Officers.  To  the best of the knowledge of the
Company,  no Key Employee of the Company or OCA-AO is a party to or bound by any
agreement, contract or commitment, or subject to any restrictions,  particularly
but without  limitation in connection  with any previous  employment of any such
person,  which materially and adversely affects, or in the future may (so far as
the Company  can  reasonably  foresee)  materially  and  adversely  affect,  the
business or  operations of the Company or OCA-AO or the right of any such person
to  participate  in the  affairs of the  Company  or OCA-AO.  To the best of the
knowledge  of  the  Company,  no Key  Employee  has  any  present  intention  of
terminating his employment  with the Company or OCA-AO and  neither the  Company
nor OCA-AO has any present intention of terminating any such employment.

         3.20. Capitalization;  Status of Capital Stock. The Company has a total
authorized  capitalization  consisting of 2,000,000  shares of Common Stock,  of
which 768,005 shares are issued and  outstanding and no shares of which are held
by the Company as Treasury  Stock.  A complete list of the  outstanding  capital
stock of the Company and the names in which such capital  stock is registered is
set forth in Exhibit 3.20 hereto. All the outstanding shares of capital stock of
the  Company  have  been duly  authorized,  are  validly  issued  and,  with the
exception of 9,638  shares  issued on March 23,  1990,  6,667  shares  issued on
September  10, 1991 and 1,000  shares  issued on March 30, 1992 which  remain in
escrow pending  satisfaction of certain  conditions  established by the Company,
are fully paid and  nonassessable.  The  shares of Common  Stock  issuable  upon
exercise  of the  Warrants,  when so issued,  will be duly  authorized,  validly
issued  and fully  paid and  nonassessable.  Except as  otherwise  indicated  on
Exhibit  3.20,  there are no options,  warrants or rights to purchase  shares of
capital  stock  or  other  securities  of  the  Company  authorized,  issued  or
outstanding, nor is the Company obligated in any other manner to issue shares of
its capital stock or other securities. There are no restrictions on the transfer
of the


<PAGE>


                                      -17-

Notes,  the Warrants or shares of Common Stock issued or issuable  upon exercise
of the  Warrants,  other  than those  imposed  by  relevant  state  and  federal
securities  laws.  No holder of any  security  of the  Company  is  entitled  to
preemptive or similar statutory or contractual  rights, either  arising pursuant
to any  agreement or  instrument  to which the Company is a party,  or which are
otherwise  binding  upon the  Company.  Neither the issuance of the Notes or the
Warrants  nor the shares of Common  Stock  issued upon  exercise of the Warrants
will  result in  an adjustment under the  antidilution or exercise rights of any
holders of any outstanding shares of capital stock,  options,  warrants or other
rights to  acquire  any  securities  of the  Company.  The offer and sale of all
shares of capital stock and other  securities  of the Company  issued before the
Closing complied with or were exempt from all federal and state securities laws.

     3.21.  Labor  Relations.  To the best of the  knowledge of the Company,  no
labor  union or any  representative  thereof has made any attempt to organize or
represent employees of the Company or OCA-AO. There are no unfair labor practice
charges,  pending trials with respect to unfair labor practice charges,  pending
material  grievance  proceedings or adverse decisions of a Trial Examiner of the
National Labor  Relations Board against the Company or OCA-AO.  Furthermore,  to
the best of the  knowledge  of the  Company,  relations  with  employees  of the
Company  and OCA-AO  are good and there is no reason to  believe  that any labor
difficulties will arise in the foreseeable future.

     3.22.  Insurance.  The Company and OCA-AO carry  insurance  covering  their
properties  and business  adequate and  customary  for the type and scope of the
properties and business,  but in any event in amounts  sufficient to prevent the
Company or OCA-AO from becoming a co-insurer.

     3.23.  Books and  Records.  The books of  account,  ledgers,  order  books,
records  and  documents  of the  Company and OCA-AO  accurately  and  completely
reflect all  material  information  relating to the  business of the Company and
OCA-AO,  the nature,  acquisition,  maintenance,  location and collection of the
assets of the Company and OCA-AO, and the nature of all transactions giving rise
to the obligations or accounts receivable of the Company and OCA-AO.

     3.24. Foreign Corrupt Practices Act. The Company has reviewed its practices
and  policies  and that of OCA-AO  and to the best of its  knowledge  and belief
neither it nor OCA-AO is engaged,  nor has any  officer,  director,  employee or
agent of the  Company or OCA-AO  engaged,  in any act or  practice  which  would
constitute  a violation of the Foreign  Corrupt  Practices  Act of 1977,  or any
rules or regulations promulgated thereunder.

     3.25.  Environmental Matters. Neither the Company nor OCA-AO has caused or,
to the best of the  Company's  knowledge,  allowed,  and neither the Company nor

Hazardous  Substances  in  connection  with the  operation  of its  business  or
otherwise except in material compliance with applicable  Environmental Laws. The
Company and OCA-AO and the operations of their  respective  business are, to the
best of the Company's  knowledge,  in material compliance with all Environmental
Laws. Except as otherwise disclosed on Exhibit 3.25 attached hereto, neither the
Company  nor  OCA-AO  has  received  any  citation,  directive,  letter or other
communication,  written  or oral,  or any notice of any  proceedings,  claims or
lawsuits,  from any  person,  entity  or  governmental  authority  alleging  any
violation or potential violation of any Environmental Law in connection with the
operation of its Business,  and the Company is not aware of any basis  therefor.
Each of the Company and OCA-AO has obtained and is currently maintaining in full
force and effect all necessary material permits, licenses and approvals referred
to in any  Environmental  Laws  applicable  to its  premises  and  the  business
conducted thereon and is in material compliance with all such permits,  licenses
and  approvals.  To the best of the  Company's  knowledge,  except as  otherwise
disclosed on Exhibit 3.25,  neither the Company nor OCA-AO has caused or allowed
a release, or a threat of release, of any Hazardous Substances onto its premises
or any other property.

     3.26.  Registration Rights.  Other than the Purchaser pursuant to the terms
of Article V hereof,  no Person has demand or other  rights to cause the Company
to file any  registration  statement  under the  Securities  Act relating to any
securities of the Company or any right to participate  in any such  registration
statement.

Subsidiary.

                               REGISTRATION RIGHTS

     5.01. "Piggy Back" Registration. If at any time the Company shall determine
to register  under the  Securities  Act  (including  pursuant to a demand of any
stockholder  of the Company  exercising  registration  rights) any of its Common
Stock of the type  which  has been or may be  issued  upon the  exercise  of the
Warrants,  other  than on Form  S-8 or its  then  equivalent  or  pursuant  to a
registration of Common Stock in connection  with a merger,  acquisition or other
transaction  of the type  described in Rule 145 registered on Form S-4, it shall
send to each holder of  Registrable  Shares,  including  each holder who has the
right to acquire Registrable  Shares,  written notice of such determination and,
if within thirty (30) days after  receipt of such notice,  such  holder shall so
request in writing,  the Company  shall use its best  efforts to include in such
registration  statement  all or any part of the  Registrable  Shares such holder
requests  be  registered,  except  that if,  in  connection  with  any  offering
involving  an  underwriting  of Common  Stock to be issued by the  Company,  the
managing underwriter shall impose a limitation on the number of


<PAGE>

                                      -29-

shares of such  Common  Stock  which may be  included  in any such  registration
statement  because,  in its judgment,  such limitation is necessary to effect an
orderly public  distribution,  and such limitation is imposed pro rata among the
holders of such  Common  Stock  having an  incidental  ("piggy  back")  right to
include such Common Stock in the registration  statement according to the amount
of such Common Stock which each holder had requested to be included  pursuant to
such right,  then the Company shall be obligated to include in such registration
statement only such limited portion of the Registrable  Shares with  respect  to
which such holder has requested inclusion  hereunder.  No incidental right under
this Section 5.01 shall be construed to limit any  registration  required  under
Section 5.02.

     5.02. Required Registration. If on any one occasion, one or more holders of
at least forty percent (40%) of the Registrable  Shares shall notify the Company
in writing  that it or they  intend to offer or cause to be  offered  for public
sale at least forty percent (40%) of the Registrable Shares, the Company will so
notify all holders of Registrable Shares, including all holders who have a right
to acquire  Registrable  Shares. Upon written request of any holder given within
thirty  (30) days after the  receipt by such  holder  from the  Company of  such
notification,  the  Company  will use its  best  efforts  to  cause  such of the
Registrable  Shares as may be requested  by any holder  thereof  (including  the
holder or holders giving the initial notice of intent to offer) to be registered
under the Securities Act as expeditiously as possible. If the Company determines
to include shares to be sold by it in any registration requests pursuant to this
Section  5.02,  such  registration  shall be deemed to have been a  registration
under Section 5.01 of this Article V.

     5.03.  Registration  on Form S-3. In addition  to the rights  provided  the
holder  of  Registrable   Shares  in  Sections  5.01  and  5.02  above,  if  the
registration  of Registrable  Shares under the Securities Act can be effected on
Form  S-3 (or any  similar  form  promulgated  by the  Securities  and  Exchange
Commission),  the Company  will  promptly  so notify each holder of  Registrable
Shares, including each holder who has a right to acquire Registrable Shares, and
then will at any time, and from time to time,  thereafter,  as  expeditiously as
possible,  use its best efforts to effect  qualification and registration  under
the  Securities  Act on said Form S-3 of all or such portion of the  Registrable
Shares as the holder or holders shall specify.

     5.04. Effectiveness.  The Company will use its best efforts to maintain the
effectiveness  for ninety (90) days from the date of its  effectiveness or until
the Registrable Shares covered thereby have been sold, whichever is earlier, and
from time to time will amend or supplement such  registration  statement and the
prospectus  contained  therein as and to the extent necessary to comply with the

<PAGE>


                                      -30-

of Registrable  Shares  with as many copies  of  the prospectus contained in any
such registration statement as it may reasonably request.

     5.05.  Indemnification  of Holder of Registrable  Shares. In the event that
the Company registers any of the Registrable Shares under the Securities Act, to
the extent  permitted by  applicable  law, the Company will  indemnify  and hold
harmless  each  holder  and  each  underwriter  of  the  Registrable  Shares  so
registered (including any broker or dealer through whom such shares may be sold)
and each person, if any, who controls such holder or any such underwriter within
the  meaning of Section 15 of the  Securities  Act from and against any and  all
losses,  claims,  damages,  expenses or liabilities,  joint or several, to which
they or any of them become  subject under the  Securities Act or under any other
statute or at common law or otherwise, and, except as hereinafter provided, will
reimburse  each such holder,  each such  underwriter  and each such  controlling
person, if any, for any legal or other expenses  reasonably  incurred by them or
any of them in connection with investigating or defending any actions whether or
not  resulting  in any  liability,  insofar  as such  losses,  claims,  damages,
expenses,  liabilities  or  actions  arise out of or are based  upon any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in the
registration  statement, in any preliminary or amended preliminary prospectus or
in the prospectus (or the  registration  statement or prospectus as from time to
time amended or  supplemented  by the Company) or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated  therein  or  necessary  in  order  to make the  statements  therein  not
misleading or any violation by the Company of any rule or regulation promulgated
under the  Securities  Act  applicable  to the Company and relating to action or
inaction  required of the Company in connection with such  registration,  unless
such untrue  statement  or  omission  was made in such  registration  statement,
preliminary  or amended,  preliminary  prospectus or prospectus in reliance upon
and in  conformity  with  information  furnished  in writing  to the  Company in
connection  therewith by such holder of Registrable Shares, any such underwriter
or any such controlling person expressly for use therein. Promptly after receipt
by any holder of Registrable Shares, any  underwriter or any controlling person,
of notice of the commencement of any action in respect of which indemnity may be
sought  against  the  Company,  such  holder  of  Registrable  Shares,  or  such
underwriter  or such  controlling  person,  as the case may be,  will notify the
Company in writing of the commencement  thereof,  and, subject to the provisions
hereinafter  stated,  the  Company  shall  assume  the  defense  of such  action
(including the employment of counsel,  who shall be counsel satisfactory to such
holder of Registrable  Shares,  such underwriter or such controlling  person, as
the case may be),  and the  payment of  expenses  insofar as such  action  shall
relate to any  alleged  liability  in respect of which  indemnity  may be sought
against the Company.  Such holder of Registrable Shares, any such underwriter or
any such  controlling  person shall have the right to employ separate counsel in
any such


<PAGE>

                                      -31-

action and to  participate  in the defense  thereof but the fees and expenses of
such counsel shall not be at the expense of the Company unless the employment of
such counsel has been specifically  authorized by the Company. The Company shall
not be liable to  indemnify  any person for any  settlement  of any such  action
effected without the Company's  consent.  The Company shall not, except with the
approval of each party being  indemnified  under this Section  5.05,  consent to
entry of any judgment or enter into any settlement  which does not include as an
unconditional  term  thereof the giving  by the  claimant  or  plaintiff  to the
parties being so  indemnified of a release from all liability in respect to such
claim or litigation.

     5.06.  Indemnification of Company.  In the event that the Company registers
any of the Registrable  Shares under the Securities Act, to the extent permitted
by applicable  law,  each holder of the  Registrable  Shares so registered  will
indemnity and hold harmless the Company, each of its directors, each of officers
who have signed the registration statement,  each underwriter of the Registrable
Shares so registered  (including  any broker or dealer  through whom such of the
shares may be sold) and each person, if any, who controls the Company within the
meaning of Section 15 of the Securities Act from and against any and all losses,
claims, damages, expenses or liabilities, joint or several, to which they or any
of them may become  subject under the  Securities Act or under any other statute
or at common  law or  otherwise,  and,  except  as  hereinafter  provided,  will
reimburse  the  Company  and  each  such  director,   officer,   underwriter  or
controlling person for any legal or other expenses  reasonably  incurred by them
or any of them in connection with investigating or defending any actions whether
or not  resulting in any  liability,  insofar as such losses,  claims,  damages,
expenses,  liabilities  or  actions  arise out of or are based  upon any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in the
registration  statement, in any preliminary or amended preliminary prospectus or
in the prospectus (or the  registration  statement or prospectus as from time to
time amended or  supplemented) or arise out of or are based upon the omission or
alleged  omission to state therein a material fact required to be stated therein
or necessary in order to make the statements  therein not  misleading,  but only
insofar as any such  statement  or  omission  was made in  reliance  upon and in
conformity  with  information  furnished in writing to the Company in connection
therewith  by such  holder of  Registrable  Shares  expressly  for use  therein;
provided,  however, that such holder's obligations hereunder shall be limited to
an amount equal to the proceeds to such holder of the Registrable Shares sold in
such  registration.  Promptly after receipt of notice of the commencement of any
action in  respect  of which  indemnity  may be sought  against  such  holder of
Registrable Shares, the Company will notify such holder of Registrable Shares in
writing of the  commencement  thereof,  and such  holder of  Registrable  Shares
shall, subject to the provisions  hereinafter stated, assume the defense of such
action (including the employment of counsel,  who shall be counsel  satisfactory
to


<PAGE>


                                      -32-

the Company) and the payment of expenses  insofar as such action shall relate to
the alleged  liability in respect of which  indemnity may be sought against such
holder of  Registrable  Shares.  The  Company and each such  director,  officer,
underwriter  or  controlling  person  shall  have the right to  employ  separate
counsel in any such action and to  participate  in the  defense  thereof but the
fees and expenses of such counsel  shall not be at the expense of such holder of
Registrable  Shares  unless  employment  of such  counsel has been  specifically
authorized  by such holder of  Registrable  Shares.  Such holder of  Registrable
Shares shall not be liable to  indemnify  any person for any  settlement  of any
such action effected without such holder's consent.

     5.07. Exchange Act Registration.  If the Company at any time shall list any
of its Common  Stock of the type which may be issued  upon the  exercise  of the
Warrants on any  national  securities  exchange and shall  register  such Common
Stock under the Exchange Act, the Company  will, at its expense,  simultaneously
list on such exchange and maintain such listing of, all of the Common Stock from
time to time  issuable upon  exercise of the  Warrants.  If the Company  becomes
subject to the reporting  requirements  of either Section 13 or Section 15(d) of
the Exchange Act,  the Company will use its best efforts to timely file with the
Securities  and Exchange  Commission  such  information  as the  Securities  and
Exchange  Commission  may require  under  either of said  Sections;  and in such
event,  the  Company  shall use its best  efforts  to take all  action as may be
required as a condition to the availability of Rule 144 under the Securities Act
(or any successor  exemptive  rule  hereinafter  in effect) with respect to such
Common  Stock.  The Company shall  furnish to any holder of  Registrable  Shares
forthwith  upon  request  (i) a  written  statement  by  the  Company  as to its
compliance with the reporting  requirements of Rule 144, (ii) a copy of the most
recent  annual or quarterly  report of the Company as filed with the  Securities
and Exchange Commission,  and (iii) such other reports and documents as a holder
may  reasonably  request in  availing  itself of any rule or  regulation  of the
Securities  and  Exchange   Commission  allowing  a  holder  to  sell  any  such
Registrable Securities without registration.

     5.08.  Damages.  The  Company  recognizes  and  agrees  that the  holder of
Registrable  Shares  will not have an adequate  remedy if the  Company  fails to
comply with this Article V and that  damages will not be readily  ascertainable,
and the Company  expressly  agrees that, in the event of such failure,  it shall
not  oppose an  application  by the  holder of  Registrable  Shares or any other
person entitled to the benefits of this Article V requiring specific performance
of any and all  provisions  hereof or enjoining  the Company from  continuing to
commit any such breach of this Article V.

     5.09.  Further  Obligations  of the Company.  Whenever  under the preceding
Sections  of this  Article V, the  Company is  required  hereunder  to  register
Registrable Shares, it agrees that it shall also do the following:


<PAGE>

            (a) Furnish to each selling  holder such copies of each  preliminary
and final  prospectus  and such other  documents  as said holder may  reasonably
request to facilitate the public offering of its Registrable Shares;

            (b) Use its best  efforts to  register  or qualify  the  Registrable
Shares covered by said registration statement under the applicable securities or
"blue sky" laws of such  jurisdictions  as any  selling  holder  may  reasonably
request;  provided,  however, that the Company shall not be obligated to qualify
to do business in any jurisdiction  where it is not then so qualified or to take
any action which would  subject it to the service of process in suits other than
those  arising  out of the  offer  or  sale  of the  securities  covered  by the
registration statement in any jurisdiction where it is not then so subject;

            (c) Furnish to each selling holder a signed counterpart of

               (i) an opinion of counsel for the  Company,  dated the  effective
     date of the registration statement, and

               (ii) "comfort" letters signed by the Company's independent public
     accountants  who have  examined  and  reported on the  Company's  financial
     statements included in the registration  statement, to the extent permitted
     by   the  standards  of  the  American   Institute  of   Certified   Public
     Accountants,

covering  substantially  the  same  matters  with  respect  to the  registration
statement  (and  the  prospectus  included  therein)  and  (in  the  case of the
accountants' "comfort" letters) with respect to events subsequent to the date of
the financial  statements,  as are  customarily  covered in opinions of issuer's
counsel and in accountants'  "comfort"  letters delivered to the underwriters in
underwritten  public offerings of securities,  to the extent that the Company is
required to deliver or cause the delivery of such  opinion or "comfort"  letters
to the underwriters in an underwritten public offering of securities;

            (d)   Permit   each   selling   holder  or  his   counsel  or  other
representatives to inspect and copy such corporate  documents and records as may
reasonably be requested by them;

            (e) Furnish to each selling holder a copy of all documents filed and
all  correspondence  from  or to  the  Securities  and  Exchange  Commission  in
connection with any such offering; and

            (f) Use  its best efforts to insure  the  obtaining of all necessary
approvals from the National Association of Securities Dealers, Inc.

     5.10 Limitations.  Notwithstanding the foregoing provisions of this Article
V:

            (a) The Company shall not be obligated to cause any  registration to
become  effective within the ninety (90) day period preceding the effective date

days  following  the  effective  date  of  the  most  recent   Company-initiated
registration;

            (b) The Company  shall not be required to maintain and keep any such
registration  effective  for a  period  exceeding  ninety  (90)  days  from  the

registration  for a period  not to exceed  ninety  (90) days from the  giving of
notice of or receipt of a request for any registration,  if the Company,  in its
good faith judgment with advice of counsel, reasonably believes that it would be
advisable to withhold the public release of information  which in the reasonable
judgment of the Company  would be required to be disclosed in such  registration
statement. 

     5.11 Letter of Opinion of Counsel in Lieu of Registration. The Company will
not be required to register any  outstanding  Registrable  Shares in  connection
with any demand made pursuant to Sections 5.01,  5.02 or 5.03 if, in the written
opinion of counsel for the Company, reasonably acceptable to such holder in form
and substance, such holder is able to sell all of its Registrable Shares without
regard  to time or volume limitations or manner of sale, in accordance with Rule
144(k) under the Securities Act and applicable state securities laws.

     5.12. Expenses.   In the case of a registration under Section 5.01, 5.02 or
5.03,  the Company shall bear all costs and expenses of each such  registration,
including,  but  not  limited  to,  printing,  legal  and  accounting  expenses,
Securities and Exchange Commission filing fees and "blue sky" fees and expenses;
provided, however, that the Company shall have no obligation to pay or otherwise
bear (i) any portion of the fees or  disbursements  of more than one counsel for
the selling holders of Registrable Shares in connection with the registration of
their Registrable  Shares, or (ii) any portion of the underwriters'  commissions
or discounts  attributable to the  Registrable  Shares being offered and sold by
the holders of Registrable Shares.

Notes; or

            (e) The Company or any Subsidiary shall fail to pay any Indebtedness
for  borrowed  money (other than as evidenced by the Notes) owing by the Company

applicable  grace  period),  whether  such  Indebtedness  shall  become  due  by
scheduled  maturity,  by  required  prepayment,  by  acceleration,  by demand or
otherwise, or  shall fail to perform any term, covenant or agreement on its part
to be performed under any agreement or instrument  (other than this Agreement or

by notice to the  Company,  declare the entire  unpaid  principal  amount of the
Notes,  all interest  accrued and unpaid  thereon and all other amounts  payable

such accrued interest and all such amounts shall become and be forthwith due and
payable  (unless there shall have occurred an Event of Default under  subsection

valuable consideration, the receipt of which is hereby acknowledged, the parties

         4.    The Company represents and warrants to MCRC as follows:

                  (a) The  Company  is a duly  organized  and  validly  existing
corporation in good standing under the laws of the Commonwealth of Massachusetts
and has all  requisite  corporate  power and  authority  for the  ownership  and
operation  of its  property  and  carrying  on of  its  business  as  now  being
conducted  and  proposed to be  conducted.  Neither  the nature of the  business
conducted by the Company nor the character of the properties owned or held under
lease by the Company  requires the Company to  be  qualified  or  licensed  as a
foreign  corporation  in any  state or  jurisdiction  other  than  the  State of
California in which it is so qualified and in good standing.

                  (b) The  Company  has all  necessary  corporate  power and has
taken all corporate action required to make all the provisions of this Agreement
and the Security Agreement the valid and enforceable obligations they purport to
be.

                  (c) No authorization, consent, approval, license, exemption of
or filing or registration with any court or governmental department, commission,
board,  bureau,  agency or  instrumentality,  domestic or foreign, is or will be
necessary  for, or in connection  with, the execution or delivery by the Company
of, or for the performance by it of its obligations under, this Agreement or the
Security Agreement.

                  (d) Neither the execution and delivery of this Agreement,  the
Security Agreement, nor the consummation of any transactions contemplated hereby
or thereby has  constituted  or resulted  in or will  constitute  or result in a
default  or  violation  of any term or  provision  of the  Company's  charter or
by-laws  or,  with notice or the  passage of time,  any  mortgages,  indentures,
leases, agreements or other instruments or any judgments,  decrees, governmental
orders,  statutes,  rules and  regulations  by which the  Company is bound or to
which its properties or assets are subject.

                  (e) That,  except for the default under Section 4.01(k) of the
Purchase  Agreement  referred to herein, no event has occurred and is continuing
which  constitutes  an Event of Default  under the  Purchase  Agreement or which
would  become  an  Event  of  default  upon a lapse  of time or with  notice  if
applicable.

evidencing other necessary corporate or other action and governmental  approval,
if any, with respect to this Agreement and the Security Agreement.

                  (b) A  certificate  of the Clerk or an Assistant  Clerk of the
Company which shall certify the names of the officers of the Company  authorized
to sign this  Agreement,  the  Security  Agreement  and the other  documents  or
certificates  to be  delivered  pursuant  to this  Agreement  and  the  Security
Agreement  by the  Company,  or any of its  officers,  together  with  the  true
signature of such officers.

                  (c) A  certificate  from  a  duly  authorized  officer  of the

Section 4.01(k) of the Purchase  Agreement  through the Company's fiscal quarter
ending  December  31,  1993,  but  waives no other  default  under the  Purchase
Agreement.  The Company  acknowledges  and agrees that upon any Event of Default
MCRC shall, at any  time and from time to time, be free, in its sole discretion,
to  exercise  any  and  all of its  rights  and  remedies  under   the  Purchase
Agreement, the Notes and the Security Agreement, including,  without limitation,
the  acceleration  of the entire  principal  and interest of the Note due to any
Event of Default.

         7. The Comany  will promptly pay all reasonable legal fees and expenses
of Testa,  Hurwitz & Thibeault,  special counsel to MCRC, in connection with the
negotiation and execution of this Agreement and the Security Agreement.

         1.    Exercise of Warrant.

                  1.1. Full  Exercise.  This Warrant may be exercised in full by
the holder hereof by surrender of this Warrant, with the form of subscription at
the end hereof duly  executed by such  holder,  to the Company at its  principal
office in the Commonwealth of Massachusetts,  accompanied by payment, in cash or
by certified or official bank check payable to the order of the Company,  in the
amount  obtained  by  multiplying  (a) the number of shares of Common  Stock for
which this Warrant is then exercisable by (b) the Purchase Price then in effect.

                  1.2. Partial  Exercise.  This Warrant may be exercised in part
by  surrender  of  this  Warrant  in the  manner  and at the place  provided  in
subsection  1.1  except  that the amount  payable by the holder on such  partial
exercise shall be the amount  obtained by multiplying  (a) the number  of shares
of Common Stock  designated by the holder in the form of subscription at the end
hereof by (b) the Purchase  Price then in effect.  On any such partial  exercise
the Company at its expense will forthwith issue and deliver to or upon the order
of the holder hereof a new Warrant or Warrants of like tenor, in the name of the
holder hereof or as such holder (upon  payment by such holder of any  applicable
transfer  taxes)  may  request,  calling in the  aggregate  on the face or faces
thereof  for the  number of shares of Common  Stock for which  such  Warrant  or
Warrants may still be exercised.

                  1.3. Payment by Notes Surrender.  Notwithstanding  the payment
provisions  of  subsections  1.1 and 1.2,  all or part of the  payment  due upon
exercise of this Warrant in full or in part may be made by the surrender by such
holder to the  Company of any of the  Company's  Notes  issued  pursuant  to the
Agreement and such Notes so surrendered  shall be credited  against such payment
in an amount  equal to the  principal  amount  thereof plus premium (if any) and
accrued interest to the date of surrender.


<PAGE>


                  1.4. Company Acknowledgment.  The Company will, at the time of
the exercise of the Warrant,  upon the request of the holder hereof  acknowledge
in writing  its  continuing  obligation  to afford to such  holder any rights to
which  such  holder  shall  continue  to be  entitled  after  such  exercise  in
accordance with the provisions of this Warrant. If the holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

                  1.5. Trustee for Warrant Holders.  In the event that a bank or
trust  company  shall  have been  appointed  as trustee  for the  holders of the
Warrants  pursuant to subsection  4.2, such bank or trust company shall have all
the powers and duties of a warrant  agent  appointed  pursuant to section 12 and
shall accept,  in its own name for the account of the Company or such  successor
person as may be entitled thereto,  all amounts otherwise payable to the Company
or such successor,  as the case may be, on exercise of this Warrant  pursuant to
this section 1.

         2.  Delivery  of  Stock  Certificates,  etc., on  Exercise. As soon  as
practicable  after the exercise of this  Warrant in full or in part,  and in any
event  within 10 days  thereafter,  the  Company at its expense  (including  the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder  hereof,  or as such holder (upon payment by such
holder  of  any  applicable   transfer  taxes)  may  direct,  a  certificate  or
certificates  for the  number of fully paid and  nonassessable  shares of Common
Stock (or Other  Securities)  to which such  holder  shall be  entitled  on such
exercise,  plus,  in lieu of any  fractional  share to which such  holder  would
otherwise  be  entitled,  cash  equal to such  fraction  multiplied  by the then
current  market value of one full share,  together with any other stock or other
securities and property  (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to section 1 or otherwise.

         3.   Adjustment   for  Dividends  in  Other  Stock,   Property,   etc.;
Reclassification,  etc. In case at any time or from time to time, the holders of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  shareholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

                  (a) other or additional  stock or other securities or property
         (other than cash) by way of dividend, or

                  (b) any cash (excluding  cash dividends  payable solely out of
         earnings or earned surplus of the Company), or

                  (c) other or additional  stock or other securities or property
         (including  cash)  by  way  of  spin-off,  split-up,  reclassification,
         recapitalization,   combination   of   shares  or   similar   corporate
         rearrangement,


<PAGE>

other  than additional  shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in subsection  5.4),  then and in each such case the holder of this Warrant,
on the  exercise  hereof as  provided in section 1, shall be entitled to receive
the amount of stock and other  securities  and property  (including  cash in the
cases  referred  to in  subdivisions  (b) and (c) of this  section 3) which such
holder  would hold on the date of such  exercise  if on the date  hereof he  had
been the holder of record of the number of shares of Common  Stock called for on
the face of this  Warrant  and had  thereafter,  during the period from the date
hereof to and including the date of such exercise,  retained such shares and all
such other or additional stock and other securities and property (including cash
in the  cases  referred  to in  subdivisions  (b)  and (c) of  this  section  3)
receivable  by him  as  aforesaid  during  such  period,  giving  effect  to all
adjustments called for during such period by sections 4 and 5.

         4. Adjustment for Reorganization, Consolidation, Merger, etc.

                  4.1.  In case at any time or from  time to time,  the  Company
shall (a) effect a reorganization,  (b) consolidate with or merge into any other
person,  or (c) transfer all or substantially all of its properties or assets to
any other person under any plan or arrangement  contemplating the dissolution of
the  Company,  then,  in each such  case,  the  holder of this  Warrant,  on the
exercise  hereof as provided in section 1 at any time after the  consummation of
such  reorganization,  consolidation  or  merger  or the  authorization  of such
dissolution  (but in no event  later than  thirty  (30) days  following  the the
effective date of such dissolution),  as the case may be, shall receive, in lieu
of the Common Stock (or Other  Securities)  issuable on such  exercise  prior to
such  consummation  or such effective  date, the stock and other  securities and
property  (including  cash) to which such holder would have been  entitled  upon
such consummation or in connection with such dissolution, as the case may be, if
such holder had so  exercised  this  Warrant,  immediately  prior  thereto,  all
subject to further adjustment thereafter as provided in sections 3 and 5.

                  4.2.  Dissolution.  In the  event  of any  dissolution  of the
Company  following the transfer of all or substantially all of its properties or
assets, the Company, prior to such dissolution,  shall at its expense deliver or
cause to be delivered  the stock and other  securities  and property  (including
cash,  where  applicable)  receivable  by the holders of the Warrants  after the
effective date of such dissolution pursuant to this section 4 to a bank or trust
company having its principal office in Boston, Massachusetts, as trustee for the
holder or holders of the Warrants.

                  4.3.   Continuation   of  Terms.   Upon  any   reorganization,
consolidation,  merger or transfer (and any dissolution  following any transfer)
referred to in this section 4, this Warrant shall


<PAGE>

continue in full force and effect and the terms  hereof shall be  applicable  to
the shares of stock and other securities and property receivable on the exercise
of this Warrant after the consummation of such reorganization,  consolidation or
merger or the effective date of dissolution  following any such transfer, as the
case may be,  and shall be  binding  upon the  issuer of any such stock or other
securities,  including,  in the case of any such transfer,  the person acquiring
all or substantially all of the properties or assets of the Company,  whether or
not such  person  shall  have  expressly  assumed  the terms of this  Warrant as
provided in section 6.

         5.  Adjustment  for  Issue or Sale of  Common  Stock  at Less  Than The
Purchase Price in Effect.

                  5.1. General. If the Company shall at any time or from time to
time,  issue any additional  shares of Common Stock (other than shares of Common
Stock excepted from the provisions of this section 5 by subsections  5.4 or 5.5)
without  consideration  or for a net  consideration  per  share  less  than  the
Purchase Price in effect  immediately prior to such issuance,  then, and in each
such case:  (a) the Purchase  Price shall be lowered to an amount  determined by
multiplying such Purchase Price then in effect by a fraction:

                           (1) the numerator of which shall be (a) the number of
         shares of Common Stock outstanding immediately prior to the issuance of
         such additional  shares of Common Stock,  plus (b) the number of shares
         of Common Stock which the net aggregate consideration, if any, received
         by the Company for the total number of such additional shares of Common
         Stock  so  issued  would  purchase  at the  Purchase  Price  in  effect
         immediately prior to such issuance, and

                           (2) the  denominator of which shall be (a) the number
         of shares of Common stock outstanding immediately prior to the issuance
         of such  additional  shares of Common Stock plus (b) the number of such
         additional shares of Common Stock so issued;

and (b) the holder of this Warrant shall  thereafter,  on the exercise hereof as
provided  in section 1, be  entitled  to receive  the number of shares of Common
Stock determined by multiplying the number of shares of Common Stock which would
otherwise  (but for the provisions of this  subsection  5.1) be issuable on such
exercise by the fraction of which (i) the numerator is the Purchase  Price which
would  otherwise (but for the provisions of this  subsection  5.1) be in effect,
and (ii) the  denominator  is the  Purchase  Price in effect on the date of such
exercise.

                  5.2. Definitions, etc.   For purposes of this section 5 and of
section 7:

                  The issuance of any warrants, options or other subscription or
         purchase rights with respect to shares of


<PAGE>

         Common Stock and the  issuance of any  securities  convertible  into or
         exchangeable  for  shares  of  Common  Stock  (or the  issuance  of any
         warrants,  options or any rights with  respect to such  convertible  or
         exchangeable  securities)  shall be deemed an  issuance at such time of
         such  Common  Stock if the Net  Consideration  Per  Share  which may be
         received  by  the  Company  for  such  Common  Stock  (as   hereinafter
         determined)  shall be less than the Purchase  Price at the time of such
         issuance  and,  except as  hereinafter  provided,  an adjustment in the
         Purchase  Price and the number of shares of Common Stock  issuable upon
         exercise of this Warrant  shall be made upon each such  issuance in the
         manner  provided  in  subsection  5.1.  Any  obligation,  agreement  or
         undertaking  to  issue  warrants,  options,  or other  subscription  or
         purchase  rights  at any time in the  future  shall be  deemed to be an
         issuance at the time such obligation,  agreement or undertaking is made
         or arises. No adjustment of the Purchase Price and the number of shares
         of Common Stock  issuable  upon  exercise of this Warrant shall be made
         under  subsection  5.1 upon the  issuance of any shares of Common Stock
         which are issued  pursuant to the exercise of any warrants,  options or
         other  subscription  or purchase  rights or pursuant to the exercise of
         any conversion or exchange rights in any convertible  securities if any
         adjustment  shall  previously  have been made upon the  issuance of any
         such  warrants,  options or other  rights or upon the  issuance  of any
         convertible  securities (or upon the issuance of any warrants,  options
         or any  rights  therefor)  as above  provided.  Any  adjustment  of the
         Purchase  Price and the number of shares of Common Stock  issuable upon
         exercise of this  Warrant  with  respect to this  subsection  5.2 which
         relates to warrants,  options or other  subscription or purchase rights
         with respect to shares of Common Stock shall be disregarded if, as, and
         when all of such warrants,  options or other  subscription  or purchase
         rights expire or are cancelled  without  being  exercised,  so that the
         Purchase  Price  effective   immediately  upon  such   cancellation  or
         expiration  shall be equal to the Purchase  Price in effect at the time
         of the issuance of the expired or cancelled warrants,  options or other
         subscriptions or purchase rights,  with such additional  adjustments as
         would  have  been  made to that  Purchase  Price  had  the  expired  or
         cancelled   warrants,   options  or  other  subscriptions  or  purchase
         rights not  been issued.  For purposes of this subsection 5.2, the "Net
         Consideration  Per Share" which may be received by the Company shall be
         determined as follows:

                           (A) The "Net  Consideration Per Share" shall mean the
                  amount  equal to the total  amount of  consideration,  if any,
                  received  by the Company  for the  issuance of such  warrants,
                  options,   subscriptions,   or  other   purchase   rights   or
                  convertible  or  exchangeable  securities,  plus  the  minimum
                  amount of  consideration,  if any, payable to the Company upon
                  exercise  or  conversion  thereof,  divided  by the  aggregate
                  number of shares of Common  Stock  that would be issued if all
                  such warrants, options,


<PAGE>

                  subscriptions,  or other  purchase  rights or  convertible  or
                  exchangeable   securities   were   exercised,   exchanged   or
                  converted.

                           (B) The "Net  Consideration  Per Share"  which may be
                  received by the Company  shall be  determined in each instance
                  as of the date of issuance of warrants, options, subscriptions
                  or other  purchase  rights,  or  convertible  or  exchangeable
                  securities  without giving effect to any possible future price
                  adjustments or rate  adjustments  which may be applicable with
                  respect  to such  warrants,  options,  subscriptions  or other
                  purchase rights or convertible securities.

         For purposes of this  section 5, if a part or all of the  consideration
         received by the Company in  connection  with the  issuance of shares of
         the Common Stock or the issuance of any of the securities  described in
         this   section  5,   consists  of  property   other  than  cash,   such
         consideration  shall  be  deemed  to have  the  same  value as shall be
         determined in good faith by the Board of Directors of the Company.

         This  subsection  5.2 shall not  apply  under any of the  circumstances
described in subsection 5.4.

                  5.3. Dilution in Case of Other  Securities.  In case any Other
Securities  shall be issued or sold,  or shall become  subject to issue upon the
conversion or exchange of any stock (or Other Securities) of the Company (or any
other issuer of Other  Securities or any other person  referred to in section 4)
or to  subscription,  purchase  or other  acquisition  pursuant to any rights or
options  granted  by the  Company  (or  such  other  issuer  or  person),  for a
consideration  per share such as to dilute the purchase rights evidenced by this
Warrant,  the computations,  adjustments and readjustments  provided for in this
section 5 with respect to the Purchase  Price and the number of shares of Common
Stock issuable upon exercise of this Warrant shall be made as nearly as possible
in the  manner  so  provided  and  applied  to  determine  the  amount  of Other
Securities from time to time  receivable on the exercise of the Warrants,  so as
to protect the holders of the Warrants against the effect of such dilution.

                  5.4. Extraordinary Events. In the event that the Company shall
(i)  issue  additional  shares  of the  Common  Stock  as a  dividend  or  other
distribution on outstanding  Common Stock, (ii) subdivide its outstanding shares
of Common  Stock,  or (iii) combine its  outstanding  shares of the Common Stock
into a smaller  number of shares of the Common Stock,  then, in each such event,
the Purchase Price shall,  simultaneously  with the happening of such event,  be
adjusted by multiplying the then Purchase Price by a fraction,  the numerator of
which  shall be the  number of shares of Common  Stock  outstanding  immediately
prior to such event and the  denominator  of which shall be the number of shares
of Common Stock outstanding immediately after such event, and the product so


<PAGE>

obtained  shall  thereafter be the Purchase  Price then in effect.  The Purchase
Price, as so adjusted, shall be readjusted in the same manner upon the happening
of any successive  event or events  described herein in this subsection 5.4. The
holder of this Warrant shall  thereafter,  on the exercise hereof as provided in
section  1, be  entitled  to  receive  that  number of  shares  of Common  Stock
determined  by  multiplying  the number of shares of Common  Stock  which  would
otherwise  (but for the provisions of this  subsection  5.4) be issuable on such
exercise by a fraction of which (i) the  numerator is the  Purchase  Price which
would  otherwise (but for the provisions of this  subsection  5.4) be in effect,
and (ii) the  denominator  is the  Purchase  Price in effect on the date of such
exercise.

                  5.5.  Excluded  Shares.  Section  5.1  shall  not apply to the
issuance of shares of Common Stock, or options therefor, to directors,  officers
and  employees of the Company  pursuant to any stock  options,  stock  purchase,
stock  ownership  or  compensation  plan  approved  by the  Company's  Board  of
Directors,  provided that the aggregate  number of shares,  and options therefor
(including  options  outstanding  on the date  hereof),  so issued to directors,
officers and employees does not exceed 150,000.

         6. No Dilution or Impairment. The Company will not, by amendment of its
Articles  of  Organization  or through any  reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of the  Warrants,  but will at all times in good  faith  assist in the
carrying  out of all such terms and in the  taking of all such  action as may be
necessary  or  appropriate  in order to protect the rights of the holders of the
Warrants against dilution or other  impairment.  Without limiting the generality
of the foregoing,  the Company (a) will not increase the par value of any shares
of stock  receivable  on the exercise of the Warrants  above the amount  payable
therefor on such exercise,  (b) will take all such action as may be necessary or
appropriate  in order that the Company may validly and legally  issue fully paid
and  nonassessable  shares of stock on the exercise of all Warrants from time to
time  outstanding,  (c) will not issue any  capital  stock of any class which is
preferred as to dividends or as to the  distribution of assets upon voluntary or
involuntary  dissolution,  liquidation  or winding up,  unless the rights of the
holders  thereof  shall be limited to a fixed sum or  percentage of par value in
respect of  participation  in dividends and in any such  distribution of assets,
and (d) will not transfer all or substantially  all of its properties and assets
to any other person (corporate or otherwise),  or consolidate with or merge into
any other person or permit any such person to consolidate with or merge into the
Company (if the Company is not the surviving  person),  unless such other person
shall  expressly  assume  in  writing  and will be bound by all the terms of the
Warrants.


<PAGE>


         7.  Accountants'  Certificate  as to  Adjustments.  In each case of any
adjustment or readjustment  in the shares of Common Stock (or Other  Securities)
issuable on the  exercise  of the  Warrants,  the  Company at its  expense  will
promptly cause independent  certified public accountants of recognized  standing
selected by the Company to compute such adjustment or readjustment in accordance
with the terms of the  Warrants  and prepare a  certificate  setting  forth such
adjustment  or  readjustment  and  showing  in detail  the facts upon which such
adjustment  or  readjustment  is  based,   including  a  statement  of  (a)  the
consideration received or receivable by the Company for any additional shares of
Common Stock (or Other Securities)  issued or sold or deemed to have been issued
or sold,  (b) the  number  of shares  of  Common  Stock  (or  Other  Securities)
outstanding  or deemed to be  outstanding,  and (c) the  Purchase  Price and the
number of shares of Common Stock to be received  upon  exercise of this Warrant,
in effect immediately prior to such issue or sale and as adjusted and readjusted
as provided in this Warrant. The Company will forthwith mail a copy of each such
certificate to each holder of a Warrant, and will, on the written request at any
time of any  holder of a  Warrant,  furnish  to such  holder a like  certificate
setting  forth the  Purchase  Price at the time in effect and showing how it was
calculated.

         8. Notices of Record Date, etc. In the event of

                           (a) any  taking  by the  Company  of a record  of the
         holders of any class or securities for the purpose of  determining  the
         holders  thereof who are  entitled to  receive any  dividend  or  other
         distribution,  or any right to  subscribe  for,  purchase or  otherwise
         acquire  any  shares of stock of any class or any other  securities  or
         property, or to receive any other right, or

                           (b) any capital  reorganization  of the Company,  any
         reclassification  or  recapitalization  of  the  capital  stock  of the
         Company or any transfer of all or  substantially  all the assets of the
         Company to or  consolidation  or merger of the Company with or into any
         other person, or

                           (c)  any   voluntary  or   involuntary   dissolution,
         liquidation or winding-up of the Company, or

                           (d) any proposed issue or grant by the Company of any
         shares of stock of any class or any other  securities,  or any right or
         option to subscribe  for,  purchase or otherwise  acquire any shares of
         stock of any class or any other securities  (other than with respect to
         the  Excluded  Shares  referred to in  subsection  5.5 and the issue of
         Common Stock on the exercise of the Warrants),

then and in each such event the Company  will mail or cause to be mailed to each
holder of a Warrant a notice specifying (i) the date on which any such record is
to be taken for the purpose of


<PAGE>

such divideend,  distribution or right,  and stating the amount and character of
such  dividend,  distribution  or  right,  (ii)  the  date  on  which  any  such
reorganization,  reclassification,  recapitalization,  transfer,  consolidation,
merger,  dissolution,  liquidation or winding-up is to take place, and the time,
if any is to be fixed,  as of which the  holders  of record of Common  Stock (or
Other Securities) shall be entitled to exchanse their shares of Common Stock (or
Other  Securities)  for  securities  or  other  property   deliverable  on  such
reorganization,  reclassification,  recapitalization,  transfer,  consolidation,
merger,  dissolution,  liquidation  or  winding-up,  and  (iii) the  amount  and
character  of any stock or other  securities,  or rights or options with respect
thereto,  proposed to be issued or granted,  the date of such proposed  issue or
grant and the persons or class of persons to whom such  proposed  issue or grant
is to be offered or made.  Such notice shall be mailed at least 20 days prior to
the date specified in such notice on which any such action is to be taken.

         9.  Reservation of Stock, etc.,  Issuable on Exercise of Warrants.  The
Company will at all times  reserve and keep  available,  solely for issuance and
delivery on the exercise of the  Warrants,  all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrants.

         10.  Exchange of Warrants.  On surrender  for  exchange of any Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         11.  Replacement  of  Warrants.   On  receipt  of  evidence  reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any

I.       WARRANTIES AND COVENANTS.

         The Debtor hereby warrants and covenants that:

         (A) The  Equipment  and  Inventory  are  used  primarily  for  business
purposes.

         (B) The  Equipment  and  Inventory  of the  Debtor  will be kept at the
Debtor's places of business,  set forth in Exhibit A attached hereto. The Debtor
will  promptly  notify the  Secured  Party of any change in the  location of the
Collateral,  and the Debtor will not remove the Equipment from the locations set
forth in Exhibit A without the prior written  consent of the Secured Party.  The
Debtor will notify the Secured  Party,  at least  twenty (20) days  prior to any
such event,  of any change in the Debtor's  exact legal name,  any change in its
places of  business or  locations  of  Equipment  or  Inventory  as set forth in
Exhibit A or its  establishment  of any new place of  business  or  location  of
Equipment  or Inventory or office  where  its records  concerning  Accounts  and
other assets are kept.

         (C) Except for (i) the security  interest  granted  hereby and (ii) the
permitted  encumbrances  set forth on Exhibit B attached  hereto (the "Permitted
Encumbrances"),  the Debtor is the owner of its presently  owned  Collateral and
will be the owner of its  Collateral  hereafter  acquired  free from any adverse
lien,  security  interest  or  encumbrance,  and  the  Debtor  will  defend  the
Collateral  against the claims and  demands of all persons at any time  claiming
the same or any interest therein.


<PAGE>

                                      - 3 -

         (D) No financing statements (other than the Permitted Encumbrances,  if
any) covering any  Collateral or any proceeds  thereof are on file in any public
office,  and at the request of Secured Party,  the Debtor will join with Secured
Party in executing one or more (i) financing  statements pursuant to the Uniform
Commercial Code, (ii) title certificate lien application  forms; and (iii) other
documents  necessary or advisable  to perfect the security  interests  evidenced
hereby,  all in form  satisfactory  to Secured Party and the Debtor will pay the
cost of filing  the same or filing or  recording  this  Agreement  in all public
offices  wherever filing or recording is deemed by Secured Party to be necessary
or desirable.

         (E) The  Debtor  will have and  maintain  insurance  at all times  with
respect  to all  its  Collateral  against  risks  of fire  (including  so-called
extended  coverage),  theft,  embezzlement and such other risks as Secured Party
may reasonably require containing such terms, in such form, for such periods and
written by such  companies as may be reasonably  satisfactory  to Secured Party;
and, if requested by the Secured Party,  all policies of insurance shall provide
for at least twenty (20) days' written  cancellation notice to Secured Party. If
and when requested by the Secured Party,  the Debtor shall furnish Secured Party
with certificates or other evidence  satisfactory to Secured Party of compliance
with the foregoing  insurance  provision and the Secured Party may act either in
its name or as attorney for the Debtor (for that purpose by these  presents duly
authorized  and appointed  with full power of  substitution  and  revocation) in
obtaining,  adjusting,  settling and cancelling such insurance and endorsing any
drafts in payment of any loss.

         (F) The Debtor will upon  request  made by the Secured  Party render to
the Secured  Party a list of all  Accounts  assigned  hereunder  and a statement
indicating the total dollar amount of the Accounts then outstanding.

         (G) The only offices  where the Debtor  keeps  records  concerning  any
Accounts  are  listed on  Exhibit A and the  Debtor  will not remove any of such
records from said offices without written consent of the Secured Party.

         (H) The Debtor will keep its  Collateral  free from any  adverse  lien,
security interest or encumbrances except the Permitted Encumbrances, if any. The
Debtor will at all times keep accurate and complete records of its Accounts, and
the Secured Party or any of its agents shall have the right at reasonable  times
and upon prior  notice,  to inspect the Debtor's  books and records  relating to
said  Accounts or to any other  transactions  to which the Debtor is a party and
from  which an  Account  might  arise and to make  extracts  from said books and
records.  The Debtor  shall  immediately  notify the Secured  Party of any event
causing  material loss or  depreciation  in value of any of its Accounts and the
amount of such loss or depreciation.


<PAGE>

                                      - 4 -

         (I) If any of a  Debtor's  Accounts  arise  out of  contracts  with the
United States or any department,  agency or instrumentality  thereof, the Debtor
will  immediately  notify the Secured  Party thereof in writing and will execute
any  instruments  and take any steps required by the Secured Party in order that
all monies due and to become due under such  contracts  shall be assigned to the
Secured  Party and notice  thereof  given to the  government  under the  Federal
Assignment of Claims Act. Notwithstanding the foregoing, the Secured Party shall
not request the Debtor to provide notice to the United States or any department,
agency or instrumentality thereof until an Event of Default has occurred.

         (J) Subsequent to the  occurrence of any Event of Default,  if any of a
Debtor's Accounts should be evidenced by promissory notes,  trade acceptances or
other instruments for the payment of money, the Debtor will immediately  deliver
same to the Secured Party,  appropriately  endorsed to the Secured Party's order
and,  regardless  of the form of such  endorsement,  such Debtor  hereby  waives
presentment,  demand or notice of any kind with respect thereto.  This Agreement
may, but need not be  supplemented  by separate  assignments  of Accounts to the
Secured  Party  and if such  assignments  are  given  the  rights  and  security
interests  given  thereby  shall be in addition to and not in  limitation of the
rights and security interests given by this Agreement.

         (K) The Debtor will pay promptly  when  due all  taxes and  assessments
upon its  Collateral or for its use or operation or upon this  Agreement or upon
any note or notes secured hereby. In its sole discretion, the Secured Party may:
(i)  discharge  taxes and liens  levied or placed on  Collateral;   (ii) pay for
insurance thereon or the maintenance and preservation  thereof;  or (iii) if the
Debtor  shall fail to make  required  deposits  in respect  of  F.I.C.A.  or any
withholding taxes, make such deposits or pay such taxes, in whole or in part, or
set up such reserves as  the Secured Party in its sole discretion deem necessary
in respect of the Debtor's liability therefor.  Any amount so paid, deposited or
reserved for shall constitute a loan for all purposes hereunder,  and the Debtor
promises  to repay the  Secured  Party such  amounts  upon the  Secured  Party's
demand.  Nothing  herein shall be deemed to obligate the Secured Party to do any
of the  foregoing and the making of any one or more such  payments;  deposits or
reserves  shall not  constitute  an agreement  by the Secured  Party to take any
further  or  similar  action  or a  waiver  of any  right of the  Secured  Party
hereunder.

         (L) The Debtor will keep its  Collateral at all times in good order and
repair, reasonable wear and tear and insured damage from fire and other casualty
excepted,  and will make necessary renewals of and replacements to the same with
goods of equal value and serviceability,  free of all liens,  security interests
and encumbrances (which are not permitted by this Agreement),  which goods shall
automatically become subject to this Agreement.

II.      ADDITIONAL RIGHTS AND ASSURANCES.

         (A) At the Secured  Party's  request,  the Debtor at its  expense  will
promptly and duly execute and deliver such  documents  and  assurances  and take
such  actions as may be  necessary  or  desirable  or as the  Secured  Party may
request in order to correct any defect,  error or omission which may at any time
be  discovered or to more  effectively  carry out the intent and purpose of this
Agreement and to  establish,  perfect and protect the Secured  Party's  security
interest, rights and remedies created or intended to be created hereunder.

         (B) Subject to Article VI of this Agreement,  the Secured Party will at
any time following an occurrence of an Event of Default hereunder have the right
to take physical possession of the Collateral and to maintain such possession on
the Debtor's  premises or to remove the  Collateral  or any part thereof to such
other places as the Secured  Party may desire.  If the Secured  Party  exercises
such  right,  the Debtor  shall at its sole  expense  upon the  Secured  Party's
request  assemble the same and make it available to the Secured Party at a place
reasonably  convenient  to  the  Secured  Party.  If  any  Inventory  is in  the
possession or control of any of the Debtor's  agents or  processors,  the Debtor
shall,  at the Secured  Party's  request,  notify  them of the  Secured  Party's
security interest therein and, at the Secured Party's request,  instruct them to
hold the same for the Secured Party's account and subject to the Secured Party's
instructions.

         (C) The Secured  Party may at any time after an  occurrence of an Event
of Default (i) in its own name or in the name of others communicate with account
debtors in order to verify with them to the  Secured  Party's  satisfaction  the
existence,  amount and terms of any Accounts and the absence of any  reductions,
discounts,  defenses or offsets with  respect  thereto,  or (ii) notify  account
debtors  that  Collateral  has been  assigned  to the  Security  Party  and that
payments by such debtors  shall be made  directly to the Secured  Party.  At the
Secured Party's request,  the Debtor will notify any or all such debtors of such
assignment,  give  instruction  and/or indicate on billings to such debtors that
their  Accounts  shall be paid to the Secured  Party and/or  supply such debtors
with a copy of this Agreement.

         (D) Subsequent to the  occurrence of any Event of Default,  the Secured
Party shall have full power, in its own name or that of the Debtor,  to collect,
endorse,  compromise,  settle,  sell or  otherwise  deal  with any or all of the
Collateral or proceeds  thereof.  Subsequent  to the  occurrence of any Event of
Default,  the Debtor  agrees upon  request of the Secured  Party to  appoint any
officer or agent of the Secured Party as true and lawful attorney-in-fact,  with
power of substitution, to endorse the name of the Debtor or any of its officers,
trustees or agents upon any Accounts,  notes,  checks,  drafts, money orders, or
other  instruments  of  payment  (including  under any  policy of  insurance  on
Collateral) or Collateral that may come into possession of the


<PAGE>


                                      - 6 -

Secured Party in full or part payment of any amounts owing to Secured Party;  to
sign and  endorse  the name of the Debtor or any of its  officers,  trustees  or
agents upon any invoice,  freight or express  bill,  bill of lading,  storage or
warehouse  receipts,  drafts against  debtors,  assignments,  verifications  and
notices in connection with Accounts,  and any instruments or documents  relating
thereto  or to the  Debtor's  rights  therein;  to give  written  notice to such
offices and officials of the United States Postal  Service to effect such change
or changes of address so that all mail  addressed to the Debtor may be delivered
directly to the Secured  Party;  to take any and all other actions  necessary or
appropriate to collect,  compromise,  settle, sell or otherwise deal with any or
all of the Collateral or proceeds  thereof;  and to obtain,  adjust,  settle and
cancel any  insurance;  hereby  granting  to each said  attorney-in-fact  or his
substitute  full power to do any and all things  necessary or  appropriate to be
done in and about the premises as fully and  effectually  as the Debtor might or
could  do,  and  hereby  ratifying  all that any  said  attorney-in-fact  or his
substitute shall lawfully do or cause to be done by virtue hereof.

         (E) The Debtor hereby assigns to the Secured Party all sums,  including
without  limitation  return of premiums,  which may become payable under any and
all of such Debtor's  policies of insurance and directs each  insurance  company
issuing any such policy to make payment which would  otherwise be due thereunder
to the Debtor directly to the Secured Party.

         (F) To the extent  permitted by Debtor's lease on any premises or place
of  business,  the  Debtor  hereby  grants  to  the  Secured  Party,  for a term
commencing on the date of the  occurrence of any Event of Default and continuing
as long as any of the Obligations remain  outstanding,  at a rental of $1.00 for
such  entire  term,  the right to the use of all  premises or places of business
which such  Debtor now or  hereafter  may have and where any  Collateral  may be
located  for  the purpose of protecting or enforcing the Secured  Party's rights
to the Collateral.

         (G) In the event of the sale,  exchange  or  disposition  of any of the
Collateral (other than finished goods in the ordinary course of business) or any
interest  therein  (and no such sale,  exchange or other  disposition  is hereby
authorized  or  consented  to),  the Secured  Party's  security  interest  shall
nevertheless  continue in such  Collateral  (including  without  limitation  all
proceeds,  cash and  non-cash)  notwithstanding  such  sale,  exchange  or other
disposition;  and the Secured  Party's receipt of any such proceeds shall not be
deemed or  construed  to be an  authorization  of or  consent  to any such sale,
exchange or other disposition.

         (H) Any and all  instruments,  documents,  policies and certificates of
insurance,  securities,  goods, accounts, choses in action, general intangibles,
chattel paper, cash,  property and the proceeds thereof (whether or not the same
are  Collateral or proceeds  thereof) owned by the Debtor or in which the Debtor
has


<PAGE>

                                      - 7 -

an interest,  which now or hereafter are at any time in possession or control of
the Secured Party or any affiliate of the Secured Party or in transit by mail or
carrier to or from the Secured Party or such  affiliate or in the  possession of
any third  party  acting in its  behalf,  without  regard to whether the Secured
Party or such affiliate received the same in pledge,  for safekeeping,  as agent
for collection or  transmission or otherwise or had  conditionally  released the
same, shall  constitute  security for Obligations and may be applied at any time
to Obligations which are then owing, whether due or not due.

         (I)  A  carbon,  photographic,  or  other  reproduction  of a  security
agreement or a financing statement is sufficient as a financing statement to the
extent permitted under applicable law.

III.     EVENTS OF DEFAULT.

         The Debtor shall be in default under this  Agreement upon the happening
of any of the following events or conditions  (individually  and collectively an
"Event of Default"):

         (A)  Failure  by the  Debtor to observe  or  perform  any  covenant  or
agreement referred to herein and, if no other grace or cure period is applicable
thereto, the continuance of such failure for fifteen (]5) business days;

         (B) Sale,  transfer or assignment of any of the  Collateral  (including
via an assignment of transfer of any interest of the Debtor) (except the sale of
inventory  in the ordinary  course of  business;  loss,  theft,  or  substantial
damage or destruction of any of the Collateral which is not fully and adequately
insured against as hereinbefore provided; or

         (C) An Event of Default (as defined in the Purchase  Agreement or under
any of the documents  referred to therein) shall have occurred and is continuing
and such Event of Default has not been annulled.

IV.      REMEDIES.

         (A) If an Event of Default occurs:

             (1) The Secured Party may declare all obligations secured hereby to
be immediately due and payable  without  presentment,  demand,  protest or other
notice of any kind, all of which are hereby expressly waived.

             (2) The  Secured  Party may  exercise  and  shall  have any and all
rights and remedies accorded it by the Massachusetts  Uniform Commercial Code or
the  Uniform  Commercial  Code as adopted in such  state  whose laws  govern the
disposition of certain Collateral. The requirement of reasonable notice shall be
met, if notice  containing such  information as may be required under applicable
law is mailed, postage prepaid, to the Debtor or other


<PAGE>


                                     - 8 -

person entitled  thereto at least  ten (10) days (including  non-business  days)
before the time of sale or disposition of the  Collateral.  The Debtor shall pay
to the Secured Party on demand any and all expenses,  including reasonable legal
expenses and reasonable  attorney's fees,  incurred or paid the Secured Party in
protecting or enforcing any rights of the Secured Party hereunder, including its
right to take possession of the Collateral, storing and disposing of the same or
in collecting the proceeds thereof.

             (3) The Debtor  designates  and appoints the Secured Party its true
and lawful  attorney with full power of  substitution  in its own name or in the
name of such  Debtor to demand, collect, receive, receipt for, sue for, compound
and give  acquittance  for,  any and all  amounts  due and to become  due on the
Accounts and to endorse the name of such Debtor on all commercial paper given in
payment or  part-payment  thereof and in its  reasonable  discretion to file any
claim or take any other  action  which the  Secured  Party may  reasonably  deem
necessary or  appropriate  to protect and preserve and realize upon the security
interest  of the Secured  Party in the  Accounts or the  proceeds  thereof.  The
Secured  Party shall also have the right to (i) open all mail  addressed  to the
Debtor;  (ii) change the Post Office box or mailing  address of the Debtor;  and
(iii) use the Debtor's stationery and billing forms or facsimiles  thereof,  for
the purpose of collecting Accounts and realizing upon the Collateral.

         (B) The Debtor  understands  and agrees the Secured  Party may exercise
its  rights  hereunder  without  affording  the  Debtor  an  opportunity  for  a
preseizure  hearing  before  the  Secured  Party,  through  judicial  process or
otherwise, takes possession of the Collateral upon the occurrence of an Event of
Default,  and the Debtor expressly waives its  constitutional  right, if any, to
such prior hearing.

         (C)  No  delay  in  accelerating  the  maturity  of any  obligation  as
aforesaid  or in taking any other action with respect to any Event of Default or
in exercising any rights with respect to the  Collateral  such affect the rights
of the Secured  Party later to take such action  with  respect  thereto,  and no
waiver as to one Event of Default shall affect rights as to any other default.

V.       MISCELLANEOUS.

         (A) The Debtor irrevocably

             (1) agrees that any suit, action, or other legal proceeding arising
out of this Agreement may be brought in the courts of record of the Commonwealth
of Massachusetts or the courts of the United States located in such state;

             (2)  consents to the  jurisdiction  of each such court  in any such
suit; action or proceeding; and


<PAGE>

                                      - 9 -

             (3) to the  extent  permitted  under  applicable  law,  waives  any
objection  which it may have to the  laying  of venue of such  suit,  action  or
proceeding  in any of such courts and waives any right to a trial by jury in any
of such courts.

         For such time as the  Obligations  shall be unpaid in whole or in part,
the Debtor  irrevocably  designates  both Donald A. Johnson and the President of
the Debtor,  and either of them, as its agent to accept and  acknowledge  on its
behalf  service of any and all  process in any such suit,  action or  proceeding
brought in any such court and agree and consent that any such service of process
upon such agent and written  notice of such service to the Debtor by  registered
or certified mail shall be taken and held to be valid personal  service upon the
Debtor whether the Debtor shall then be doing business  within the  Commonwealth
of Massachusetts and that any such service of process shall be of the same force
and validity as if service were made upon it according to the laws governing the
validity and requirements of such service in such states and waives all claim of
error by reason of any such  service.  Any notice,  process,  pleadings or other
papers served upon the aforesaid  designated  agent shall,  at the same time, be
sent by certified or registered mail to the Debtor.

         (B) In case any one or more of the provisions  contained  herein should
be invalid,  illegal or unenforceable in any respect, the validity,  legality or
enforceability of the remaining provisions contained herein shall not in any way
be affected or impaired thereby.

         (C) All  rights  of the  Secured  Party  hereunder  shall  inure to the
benefit of its successors and assigns;  and all  obligations of the Debtor shall
bind the  successors  or  assigns  of the  Debtor.  All the  provisions  of this
Agreement  shall be construed by and  administered  in accordance with the local
laws of the Commonwealth of Massachusetts. This Agreement shall become effective
when it is signed by the Debtor.  The Debtor  acknowledges  receipt of a copy of
this Agreement.

         (D) In the absence of gross negligence or willful  misconduct,  neither
the Secured Party nor any  attorney-in-fact  appointed hereunder shall be liable
to the Debtor or any other person for any act or  omission,  any mistake of fact
or any error of judgment in exercising any right or remedy granted herein.

VI.      FIRST RIGHTS OF OTHER SECURED CREDITORS.

         The  Secured  Party and the  Debtor  acknowledge  that the  Debtor  has
granted a security interest to Massachusetts  Business Development  Corporation,
Fleet Credit  Corporation and Bank of the West  (collectively the "Other Secured
Creditors")  to secure  certain  obligations  of the Debtor to the Other Secured
Creditors.  The Secured Party and the Debtor hereby  expressly  acknowledge that
the security interest in the Collateral created hereby is subordinate and junior
to the security interest of the Other

To the Purchaser(s) named on Schedule I
attached hereto

         Re:   11% Subordinated Notes due 1997 and
               Common Stock Purchase Warrants

Dear Purchaser:

         Optical  Corporation  of  America,  a  Massachusetts  corporation  (the
"Company"),   hereby  agrees  with  you   (individually   and  collectively  the
"Purchaser") as follows:

                                    ARTICLE I

                 PURCHASE, SALE AND TERMS OF NOTES AND WARRANTS

         1.01.  The Notes.  The Company has  authorized the issuance and sale to
the Purchaser  (and to one or more other  Purchasers,  including  those named in
Exhibit  3.07,  who may now or at any time prior to July 31,  1993 enter into an
agreement in  substantially  the form of this Agreement,  sometimes  hereinafter
referred to as the "Other  Purchasers") of the Company's 11% Subordinated  Notes
due July 1, 1997, in an aggregate  original  principal  amount not to exceed the
sum of $750,000.  The 11% Subordinated Notes are to be substantially in the form
set forth in Exhibit 1.01 hereto and are herein  referred to  individually  as a
"Note" and collectively as the "Notes", which terms shall also include any notes
subsequently delivered in exchange or replacement therefor.

         1.02.  The Warrants.  The Company has also  authorized the issuance and
sale to the  Purchaser and the Other  Purchasers  of the Company's  Common Stock
Purchase  Warrants for the purchase  (subject to adjustment as provided therein)
of not to exceed 24,000 shares of the Company's Common Stock of the par value of
$.01 per share;  and such Warrants will be issued at the rate of one Warrant for
800 shares of Common Stock for each $25,000  principal  amount of the Notes. The
Common Stock Purchase  Warrants are to be substantially in the form set forth in
Exhibit 1.02 hereto and are herein  referred to  individually as a "Warrant" and
collectively  as the  "Warrants",  which terms shall also  include any  warrants
subsequently delivered in exchange or replacement therefor.

             1.03.     Purchase and Sale of Notes and Warrants.

                      (a) The  Closing. The  Company  will issue and sell to the
Purchaser, and, subject to and in reliance upon the


<PAGE>


representations,  warranties,  terms  and  conditions  of  this  Agreement,  the
Purchaser  will  purchase a Note and a Warrant for an aggregate  purchase  price
equal to the principal  amount of the Note set opposite the Purchaser's  name on
Schedule I hereto.  Such  purchase  and sale shall take place at a closing  (the
"Closing") to be held at the offices of Messrs. Bowditch & Dewey, 311  Main St.,
Worcester, Massachusetts on such date and at such time as may be mutually agreed
upon by the Company and the Purchaser, but in no event later than June 30,1993.

         At the Closing the Company will  initially  issue one Note,  payable to
the order of the  Purchaser,  in the  principal  amount set forth  opposite  the
Purchaser's name on Schedule I hereto and one Warrant, registered in the name of
the  Purchaser,  to purchase  (subject to  adjustment  as provided  therein) the
number  of shares  which is also set  forth  opposite  the  Purchaser's  name on
Schedule I hereto,  of the  Company's  Common  Stock,  against  delivery  to the
Company of a check or a receipt of a wire  transfer,  in an amount  equal to the
principal amount of the Note being purchased by the Purchaser, in payment of the
full purchase price for the Note and Warrant.

                      (b)  Allocation  of  Purchase  Price.  The Company and the
Purchaser,  having adverse interests and as a result of arm's length bargaining,
have established that (i) the Purchaser has not rendered or agreed to render any
services to the Company in connection with this Agreement or the issuance of any
of the Notes and Warrants;  (ii) the Purchaser's  Warrant is not being issued as
compensation;  and (iii) the price at which the Notes would be issued if it were
assumed that they were issued apart from the Warrants is an amount equal to 100%
of the  aggregate  principal  amount  thereof.  The  Company  and the  Purchaser
recognize  that the agreement  specified  herein  establishes  that the original
issue discount to be taken into account as such by the Company and the Purchaser
for federal  income tax  purposes  with respect to the sale of the Note is Zero,
and they will adhere to the agreement specified herein for such purposes.

                      (c)  Use of  Proceeds.  The  Company  will  use  the  full
proceeds from the sale of the Notes and Warrants for the  refinancing of current
obligations for indebtedness for money borrowed and for working capital.

         1.04. Payments and Endorsements.  Payments of principal and interest on
the Notes,  shall be made  directly  by check duly  mailed or  delivered  to the
Purchaser at the address specified on Schedule I hereto, without any presentment
or  notation  of payment,  except  that prior to any  transfer of any Note,  the
holder  of  record  shall  endorse  on such  Note a record  of the date to which
interest  has been paid and all  payments  made on account of  principal of such
Note.

                                       -2-


<PAGE>


         1.05. Redemptions.

                      (a) Required  Redemptions.  On July 1, 1995 and on July 1,
1996 the Company will redeem, without premium, twenty-five per cent (25%) of the
original  principal  amount of, and on July 1, 1997 all of the  balance  of, the
principal amount of the Notes, or such lesser amount as may be then outstanding,
together  with  all  accrued  and  unpaid  interest  then due on the  amount  so
redeemed.  On the stated or accelerated  maturity of the Notes, the Company will
pay the principal amount of the Notes then outstanding together with all accrued
and unpaid interest then due thereon. No optional redemption of less than all of
the outstanding principal amount of the Notes shall affect the obligation of the
Company to make the redemptions required by this subsection.

                      (b) Optional  Redemptions  Without Premium. In addition to
the  redemptions of the Notes on each required  redemption  date with respect to
the Notes,  the Company may also voluntarily  redeem,  together with all accrued
and unpaid  interest  then due  thereon,  but  without  premium,  an  additional
principal  amount  of the  Notes  not  to  exceed  the  amount  of the  required
redemption  due on such date.  The right of  redemption  of the Notes under this
subsection 1.05(b) shall not be cumulative.

                      (c) Notice of Redemptions; Pro rata Redemptions. No notice
of an optional  redemption  pursuant to subsection  1.05(b) need be given.  Each
redemption  of Notes  shall be made so that the Notes  then held by each  holder
shall be redeemed in a principal  amount  which shall bear the same ratio to the
total principal  amount of Notes being redeemed as the principal amount of Notes
then held by such holder bears to the  aggregate  principal  amount of the Notes
then outstanding

         1.06  Registration,  etc. The Company  shall  maintain at its principal
office a register of the Notes and shall record  therein the names and addresses
of the registered  holders of the Notes,  the address to which notices are to be
sent and the  address  to which  payments  are to be made as  designated  by the
registered  holder if other than the address of the holder,  and the particulars
of all transfers,  exchanges and  replacements  of Notes.  No transfer of a Note
shall be valid  unless made on such  register for the  registered  holder or his
executors  or  administrators  or his or their  duly  appointed  attorney,  upon
surrender  thereof  for  exchange as  hereinafter  provided,  accompanied  by an
instrument in writing,  in form and  execution  reasonably  satisfactory  to the
Company.  Each Note  issued  hereunder,  whether  originally  or upon  transfer,
exchange or replacement  of a Note or Notes,  shall be registered on the date of
execution  thereof by the Company and shall be dated the date to which  interest
has been paid on such Notes or Note.  The  registered  holder of a Note shall be
that  Person in whose name the Note has been so  registered  by the  Company.  A
registered  holder  shall be deemed the owner of a Note for all purposes of this
Agreement  and,  subject to the  provisions  hereof,  shall be  entitled  to the
principal,  premium,  if any, and interest  evidenced by such Note free from all
equities or rights


                                       -3-

of setoff  or  counterclaim  between  the  Company  and the  transferor  of such
registered holder or any previous registered holder of such Note.

         1.07. Transfer and Exchange of Notes. The registered holder of any Note
or Notes may,  prior to maturity or prepayment  thereof,  surrender such Note or
Notes at the principal office of the Company for transfer or exchange.  Within a
reasonable  time after  notice to the Company  from a  registered  holder of its
intention to  make such exchange and without expense (other than transfer taxes,
if any) to such registered  holder, the Company shall issue in exchange therefor
another Note or Note,  in such  denominations  as  requested  by the  registered
holder,  for the same aggregate  principal amount as the unpaid principal amount
of the Note or Notes so  surrendered,  and having the same  maturity and rate of
interest,  containing  the same  provisions  and  subject  to the same terms and
conditions  as the  Note or Notes so  surrendered.  Each new Note  shall be made
payable to such Person or Persons,  or  registered  assigns,  as the  registered
holder of such  surrendered  Note or Notes may in  writing  designate,  and such
transfer  or  exchange  shall be made in such a  manner  that no gain or loss of
principal or interest shall result therefrom.

         1.08.  Replacement of Notes.  Upon receipt of evidence  satisfactory to
the Company of the loss,  theft,  destruction  or mutilation of any Note and, if
requested in the case of any such loss,  theft or destruction,  upon delivery of
an indemnity bond or other agreement or security reasonably  satisfactory to the
Company, or, in the case of any such mutilation, upon surrender and cancellation
of such Note,  the Company  will issue a new Note,  of like tenor and amount and
dated the date to which  interest has been paid,  in lieu of such lost,  stolen,
destroyed or mutilated Note.

         1.09  Subordination.  The  Company,  for  itself,  its  successors  and
assigns,  covenants and agrees,  and the Purchaser and each successor  holder of
the Notes by his or its acceptance thereof,  likewise covenants and agrees, that
notwithstanding  any other provision of this Agreement or the Notes, the payment
of the  principal  of and  interest  on  each  and  all of the  Notes  shall  be
subordinated  in right of payment,  to the extent and in the manner  hereinafter
set  forth,  to the prior  payment in full of all  Senior  Debt (as  hereinafter
defined) at any time  outstanding.  The  provisions  of this  Section 1.09 shall
constitute a continuing representation to all Persons who, in reliance upon such
provisions,  become the holders of or continue  to hold  Senior  Debt,  and such
provisions  are made for the  benefit of the  holders of Senior  Debt,  and such
holders are hereby made obligees  hereunder to the same extent as if their names
were written herein as such, and they or any of them may proceed to enforce such
provisions  against the  Company or against  the holder of any Note  without the
necessity of joining the Company as a party.

                      (a) Payment of Senior Debt. In the event of any insolvency
or bankruptcy proceedings, or any receivership,

                                        -4-


<PAGE>


liquidation,   reorganization   or  other  similar   proceedings  in  connection
therewith,  relative to the Company or to its property,  or, in the event of any
proceedings  for voluntary  liquidation,  dissolution or other winding up of the
Company or  distribution  or marshalling of its assets or any  composition  with
creditors of the Company,  whether or not involving  insolvency  or  bankruptcy,
when and in any such  event all  Senior  Debt  shall be paid in full  before any
payment or distribution of any character,  whether in cash,  securities or other
property,  shall  be made on  account  of the  Notes;  and any such  payment  or
distribution  (except  securities  which are  subordinate and junior in right of
payment  to the  payment  of all  Senior  Debt  then  outstanding  in  terms  of
substantially  the same tenor as this Section  1.09),  which would,  but for the
provisions  hereof,  be payable or  deliverable in respect of the Notes shall be
paid or  delivered  directly  to the  holders  of  Senior  Debt (or  their  duly
authorized  representatives),  in the  proportions  in which they hold the same,
until all  Senior  Debt shall  have been paid in full,  and every  holder of the
Notes by becoming a holder thereof shall, by his or its acceptance  thereof,  be
deemed to have  designated  and  appointed  the holder or holders of Senior Debt
(and  their  duly  authorized   representatives)   as  his  or  its  agents  and
attorneys-in-fact  to demand,  sue for,  collect  and  receive  such Senior Debt
holder's  ratable share of all such payments and  distributions  and to file any
necessary  proof of claim  therefor and to take all such other action for and in
the name of the holders of the Notes or  otherwise,  as such Senior Debt holders
(or  their  authorized   representatives)  may  determine  to  be  necessary  or
appropriate  for the  enforcement  of this Section 1.09.  The Purchaser and each
successor  holder  of the  Notes  by his or its  acceptance  thereof  agrees  to
execute,  at the request of the Company, a separate agreement with any holder of
Senior Debt on the terms set forth in this  Section  1.09,  and to take all such
other action as such holder or such holder's representative may request in order
to enable such holder to enforce all claims upon or in respect of such  hoider's
ratable share of the Notes.

                      (b) No Payment on Notes Under Certain  Conditions.  In the
event that any default  occurs in the payment of the principal of or interest on
any Senior Debt (whether as a result of the acceleration  thereof by the holders
of such Senior Debt or otherwise) and during the continuance of such default for
a period up to sixty (60) days and thereafter if judicial proceedings shall have
been instituted with respect to such defaulted payment, or (if a shorter period)
until such  payment  has been made or such  default  has been cured or waived in
writing by such holder of Senior Debt,  then and during the  continuance of such
event no payment of  principal  of or interest on the Notes shall be made by the
Company or accepted by any holder of the Notes who has received  written  notice
from the Company or from a holder of Senior Debt of such events.

                      (c)  Payments  Held in  Trust.  In  case  any  payment  or
distribution  shall be paid or  delivered  to any holder of the Notes before all
Senior  Debt  shall  have  been  paid  in  full,  despite  or  in  violation  or
contravention of the terms of this Section 1.09, such


                                       -5-
<PAGE>


payment  or  distribution  shall  be held in trust  for and  paid and  delivered
ratably   to  the   holders   of   Senior   Debt  (or  their   duly   authorized
representatives), until all Senior Debt shall have been paid in full.

                      (d)  Subrogation.  Subject  to the  payment in full of all
Senior Debt and until the Notes shall be paid in full,  the holders of the Notes
shall be  subrogated  to the rights of the holders of Senior Debt (to the extent
of  payments or  distributions  previously  made to such  holders of Senior Debt
pursuant to the provisions of  subsections  (a) and (c) of this Section 1.09) to
receive  payments or  distributions  of assets of the Company  applicable to the
Senior Debt.  No such  payments or  distributions  applicable to the Senior Debt
shall,  as between  the  Company  and its  creditors,  other than the holders of
Senior  Debt and the  holders  of the  Notes,  be deemed to be a payment  by the
Company to or on account of the Notes; and for the purposes of such subrogation,
no payments or  distributions to the holders of Senior Debt to which the holders
of the Notes would be entitled  except for the  provisions  of this Section 1.09
shall,  as between  the  Company  and its  creditors,  other than the holders of
Senior  Debt and the  holders  of the  Notes,  be deemed to be a payment  by the
Company to or on account of the Senior Debt.

                      (e) Scope of Section.  The provisions of this Section 1.09
are  intended  solely for the purpose of  defining  the  relative  rights of the
holders of the Notes,  on the one hand,  and the holders of the Senior Debt,  on
the other hand.  Nothing  contained  in this  Section  1.09 or elsewhere in this
Agreement or the Notes is intended to or shall  impair,  as between the Company,
its  creditors  other than the  holders of Senior  Debt,  and the holders of the
Notes, the obligation of the Company,  which is unconditional  and absolute,  to
pay to the holders of the Notes the  principal  of and  interest on the Notes as
and when the same shall  become due and  payable  in  accordance  with the terms
thereof,  or to  affect  the  relative  rights of the  holders  of the Notes and
creditors of the Company  other than the holders of the Senior  Debt,  nor shall
anything  herein or therein  prevent the holder of any Note from  accepting  any
payment with respect to such Note or exercising all remedies otherwise permitted
by applicable law upon default under such Note,  subject to the rights,  if any,
under  this  Section  1.09 of the  holders  of Senior  Debt in  respect of cash,
property or securities of the Company received by the holders of the Notes.

     (f) Survival of Rights. The right of any present or future holder of Senior
Debt to enforce  subordination  of the Notes  pursuant to the provisions of this
Section  1.09  shall not at any time be  prejudiced  or  impaired  by any act or
failure  to act on the part of the  Company or any such  holder of Senior  Debt,
including,  without limitation,  any forbearance,  waiver, consent,  compromise,
amendment, extension, renewal, acceptance or taking or release of security of or
in respect of any Senior Debt, or by noncompliance

                                       -6-


<PAGE>


by the Company with the terms of such subordination  regardless of any knowledge
thereof such holder may have or otherwise be charged with.

                      (g)  Amendment or Waiver.  The  provisions of this Section
1.09 may not be  amended  or waived in any manner  which is  detrimental  to any
Senior  Debt  without  the  requisite  consent of the holders of any Senior Debt
according to the applicable provisions thereof.

                      (h) Senior Debt Defined. The term "Senior Debt" shall mean
(i) all  Indebtedness  of the  Company  for money  borrowed  from banks or other
institutional  lenders,  including any extensions or renewals  thereof,  whether
outstanding on the date hereof or thereafter  created or incurred,  which is not
by its terms or by separate  agreement  subordinate and junior to or on a parity
with (x) the  Notes  and (y) the  Subordinated  Notes  due 1999 in the  original
principal  amount of $1,500,000  issued pursuant to an Agreement dated as of May
28, 1992 between the Company and  Massachusetts  Capital  Resource  Company (the
"1992 Notes"), and which is permitted by the terms of this Agreement at the time
it is created or incurred,  and (ii) all guaranties by the Company which are not
by their terms or by separate agreement subordinate and junior to or on a parity
with the Notes and the 1992 Notes and which are  permitted  by the terms of this
Agreement at the time they are made, of  Indebtedness  of any Subsidiary if such
Indebtedness  would have been Senior Debt  pursuant to the  provisions of clause
(i) of this  sentence had it been  Indebtedness  of the  Company.  In making any
loans which are (or the guaranties of which are) intended to be Senior Debt, the
lenders or purchasers thereof shall be entitled to rely as to the fact that such
Indebtedness or guaranty is permitted hereby upon a certificate by the Company's
chief financial  officer  purporting to show such  Indebtedness or guaranty will
not result in the Company's  failure to comply with the provisions of Article IV
hereof in effect as of the date of the loan or guaranty.

         1.10.  Representations by the Purchaser.  The Purchaser represents that
it is  acquiring  the Note and Warrant for its own account and that the Note and
Warrant are being and will be acquired  for the  purpose of  investment  and not
with a view to  distribution  or resale  thereof or of the Common Stock or other
securities receivable upon the exercise of the Warrants.  The acquisition by the
Purchaser  of the Note and  Warrant  shall  constitute  a  confirmation  of this
representation.

                                   ARTICLE II

                      CONDITIONS TO PURCHASER'S OBLIGATION

the Company  establishing  the identity of the officers  authorized to sign this
Agreement,  the Note, the Warrant and the other  documents or certificates to be

                      (d) A certificate  from a duly  authorized  officer of the
Company  stating  that (i) the  representations  and  warranties  of the Company
contained in Article III hereof and otherwise  made by the Company in writing in
connection with the transactions  contemplated hereby are true and correct,  and
(ii) no  condition or event has  occurred or is  continuing  or will result from
execution  and  delivery  of this  Agreement,  the Notes or the  Warrants  which

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants as follows:

         3.01.  Organization  and Standing.  The Company is a duly organized and
validly existing corporation in good standing under the laws of the Commonwealth
of  Massachusetts  and has all requisite  corporate  power and authority for the
ownership  and  operation  of its  properties  and  for the  carrying  on of its
Business.  Neither the nature of the business conducted by the Company,  nor the
character of the properties owned or held under lease by the Company requires it
to  be  qualified  or  licensed  as  a  foreign  corporation  in  any  state  or
jurisdiction  other than the State of California,  in which it is duly qualified
and in good standing. The Company has no Subsidiaries.

                                       -8-


<PAGE>


         3.02.  Corporate Action. The Company has all necessary  corporate power
and has taken all corporate  action  required to make all the provisions of this
Agreement,  the Notes,  the Warrants,  and any other  agreements and instruments
executed  in  connection  herewith  and  therewith  the  valid  and  enforceable
obligations  they purport to be.  Sufficient  shares of authorized  but unissued
Common Stock of the Company have been reserved by appropriate  corporate  action
in order to permit the  exercise of the  Warrants.  Neither the  issuance of the
Notes or Warrants,  nor the issuance of shares of Common Stock upon the exercise
of the  Warrants,  is  subject  to  preemptive  or other  similar  statutory  or
contractual rights and will not conflict with any provisions of any agreement or
instrument to which the Company is a party or by which it is bound.

         3.03.  Governmental  Approvals.  No authorization,  consent,  approval,
license,  exemption of or filing or registration  with any court or governmental
department,  commission,  board, bureau, agency or instrumentality,  domestic or
foreign,  is or will  be  necessary  for,  or in  connection  with,  the  offer,
issuance,  sale, execution or delivery by the Company of, or for the performance
by it of its obligations under, this Agreement, the Notes or the Warrants.

         3.04.  Litigation.  Except as is set forth on Exhibit 3.04, there is no
litigation  or  governmental  proceeding  or  investigation  pending  or, to the
knowledge of the Company,  threatened  against the Company  affecting any of its
properties or assets, where such litigation, proceeding or investigation, either
individually  or in the aggregate,  would have a material  adverse effect on the
Company;  nor, to the knowledge of the Company,  has there occurred any event or
does there exist any condition on the basis of which any litigation,  proceeding
or  investigation  might properly be  instituted.  The Company is not in default
with respect to any order, writ,  injunction,  decree, ruling or decision of any
court, commission, board or other government agency affecting the Company. There
are no actions or proceedings pending or threatened (or any basis therefor known
to the Company) which might result,  either in any case or in the aggregate,  in
any material adverse change in the business, operations, affairs or condition of
the  Company or in any of its  properties  or assets,  or which  might call into
question the validity of this Agreement, the Notes or the Warrants or any action
taken or to be taken pursuant hereto or thereto.

         3.05.  Compliance with Other Instruments.  The Company is in compliance
in all  respects  with the terms and  provisions  of this  Agreement  and of its
Articles of Organization and bylaws and in all material  respects with the terms
and  provisions  of the  mortgages,  indentures,  leases,  agreements  and other
instruments, and of all judgments, decrees, governmental orders, statutes, rules
and  regulations,  by which it is bound or to which its properties or assets are
subject,  except as set forth on Exhibit 3.05.  There is no term or provision in
any of the foregoing

                                       -9-


<PAGE>


documents  and  instruments  which  materially  adversely  affects the business,
assets or financial condition of the Company. Neither the execution and delivery
of this  Agreement,  the  Notes or the  Warrants,  nor the  consummation  of any
transactions  contemplated hereby or thereby,  constitutes or results in or will
constitute  or result in a default or  violation of any term or provision in any
of the foregoing documents or instruments.

         3.06. Financial  Information.  The consolidated financial statements of
the Company (and of its former Subsidiary,  OCA Applied Optics,  Inc., which was
merged into the  Company  effective  March 31,  1993)  attached as Exhibit  3.06
present  fairly the  consolidated  financial  position  of the  Company and such
Subsidiary as at the dates thereof and the results of their  operations  for the
periods  covered  thereby and have been  prepared in accordance  with  generally
accepted accounting principles consistently applied. The financial statements so
attached  are:  (1) for the two years  ended  June 30,  1992 and June 30,  1991,
certified  by Deloitte & Touche and (ii) for the  nine-month  period ended March
31, 1993,  being  unaudited  and subject to year-end  adjustments  consisting of
normal recurring items which will not be material in the aggregate.  The Company
has no  liability,  contingent  or  otherwise,  not  disclosed in the  aforesaid
financial statements or in the notes thereto that could,  together with all such
other liabilities, materially affect the financial condition of the Company, nor
does the  Company  have any  reasonable  grounds to know of any such  liability.
Except  as set  forth in  Exhibit  3.06(a),  since  the  date of the  nine-month
financial  statements for the period ended March 31, 1993, (i) there has been no
adverse  change in the business,  assets or  condition,  financial or otherwise,
operations or prospects,  of the Company; (ii) neither the business,  condition,
operations  or prospects of the Company nor any of its  properties or assets has
been adversely affected as a result of any legislative or regulatory change, any
revocation or change in any franchise,  license or right to do business,  or any
other event or occurrence, whether or not insured against; (iii) the Company has
not incurred any additional Indebtedness for money borrowed or redeemed, whether
in whole or in part, any Indebtedness  for money borrowed;  (iv) the Company has
not purchased or sold any assets, other than in the ordinary course of business;
(v) the Company has not issued or sold any of its capital stock, or any options,
warrants or convertible  securities  exercisable therefor;  and (vi) the Company
has not entered into any material  transaction or made any  distribution  on its
capital stock.

         3.07.  Securities  Act.  Neither the  Company nor anyone  acting on its
behalf has offered the Notes or the Warrants or similar securities, or solicited
any offers to  purchase  or made any  attempt  by  preliminary  conversation  or
negotiations  to dispose of the Notes,  Warrants or similar  securities,  to any
Person  other than the  Purchaser or the Other  Purchasers  described in Exhibit
3.07.  Neither the  Company nor anyone  acting on its behalf has offered or will
offer to sell the Notes,  Warrants or similar  securities  to, or solicit offers
with respect thereto from, or


                                      -10-


<PAGE>


enter into any preliminary  conversations or negotiations relating thereto with,
any Person, so as to bring the issuance and sale of the Notes and Warrants under
the registration provisions of the Securities Act.

         3.08.  Disclosure.  Neither this  Agreement,  the financial  statements
incorporated  herein  as  Exhibit  3.06,  nor  any  other  agreement,  document,
certificate,  schedule,  exhibit or written statement furnished to the Purchaser
by or on behalf of the Company in connection with the transactions  contemplated
hereby,  contains any untrue  statement  of a material  fact or omits to state a
material  fact  necessary in order to make the  statements  contained  herein or
therein not  misleading.  There is no fact which to the knowledge of the Company
has not been disclosed  herein or in writing by the Company to the Purchaser and
which materially adversely affects, or in the future may, insofar as the Company
can now foresee, materially adversely affect the business, properties, assets or
condition, financial or otherwise, of the Company.

         3.09. No Brokers or Finders. No Person has or will have, as a result of
the transactions  contemplated by this Agreement,  any right,  interest or valid
claim against or upon the Company for any commission,  fee or other compensation
as a finder or broker  because  of any act or  omission  by the  Company  or any
agent of the Company.

         3.10. Capitalization;  Status of Capital Stock. The Company has a total
authorized  capitalization  consisting of 2,000,000  shares of Common Stock,  of
which 768,005 shares have been issued,  765,277 shares are  outstanding and 2728
shares are held by the Company as Treasury Stock. All the outstanding  shares of
capital stock of the Company have been duly  authorized,  are validly issued and
are fully paid and  nonassessable.  The  shares of Common  Stock  issuable  upon
exercise  of the  Warrants,  when so issued,  will be duly  authorized,  validly
issued  and fully  paid and  nonassessable.  Except as  otherwise  indicated  on
Exhibit  3.10,  there are no options,  warrants or rights to purchase  shares of
capital  stock  or  other  securities  of  the  Company  authorized,  issued  or
outstanding, nor is the Company obligated in any other manner to issue shares of
its capital stock or other securities. There are no restrictions on the transfer
of the Notes,  the Warrants or shares of Common  Stock  issued or issuable  upon
exercise of the Warrants, other than those imposed by relevant state and federal
securities  laws.  No holder of any  security  of the  Company  is  entitled  to
preemptive or similar statutory or contractual  rights,  either arising pursuant
to any  agreement or  instrument  to which the Company is a party,  or which are
otherwise  binding  upon the  Company.  Neither the issuance of the Notes or the
Warrants nor the issuance of the shares of Common Stock  issuable  upon exercise
of the Warrants will result in an adjustment  under the antidilution or exercise
rights of any  holders  of any  outstanding  shares of capital  stock,  options,
warrants or other rights to acquire any securities of the Company. The offer and
sale of all

                                      -11-


<PAGE>


shares of capital stock and other  securities  of the Company  issued before the
Closing complied with or were exempt from all federal and state securities laws.

unpaid,  might become a lien or charge upon any properties of the Company or any
Subsidiary,  provided  that  neither  the Company  nor the  Subsidiary  shall be
required to pay any such tax,  assessment,  charge, levy or claim which is being
contested  in good  faith  and by  appropriate  proceedings  if the  Company  or
Subsidiary  concerned  shall have set aside on its books adequate  reserves with
respect  thereto,  except  such as are  being  contested  in good  faith  and by

to which  interest  has been paid on the  surrendered  Note and in an  aggregate

                         OPTICAL CORPORATION OF AMERICA

                          Common Stock Purchase Warrant

         OPTICAL  CORPORATION  OF  AMERICA,  a  Massachusetts  corporation  (the
"Company"),  hereby  certifies  that, for value received  Stephen B. Loring,  or
registered  assigns,  is  entitled,  subject  to the terms set forth  below,  to
purchase  from the  Company at any time or from time to time  before  5:00 P.M.,
Boston time,  on July 1, 1997, or such later time as may be specified in Section
17 hereof,  4,000 fully paid and nonassessable  shares of Common Stock, $.01 par
value, of the Company,  at a purchase price per share of Eleven Dollars ($11.00)
(such purchase price per share as adjusted from time to time as herein  provided
is referred to herein as the "Purchase Price"). The number and character of such
shares of Common  Stock and the  Purchase  Price are  subject to  adjustment  as
provided herein.

         This  Warrant  is  one of  the  Common  Stock  Purchase  Warrants  (the
"Warrants")  evidencing  the right to  purchase  shares  of Common  Stock of the
Company,  issued pursuant to a certain  Subordinated  Note and Warrant  Purchase
Agreement (the "Agreement"),  dated as of June 30, 1993, between the Company and
the  original  Purchaser  of this  Warrant,  a copy of  which  is on file at the
principal  office of the Company in the Commonwealth of  Massachusetts;  and the
holder  of  this  Warrant  shall  be  entitled  to all of  the  benefits  of the
Agreement, as provided therein.

         As used  herein  the  following  terms,  unless the  context  otherwise
requires, have the following respective meanings:

                      (a) The term "Company" shall include  Optical  Corporation
of America and any corporation  which shall succeed to or assume the obligations
of the Company hereunder.

                      (b) The term "Common  Stock"  includes  (a) the  Company's
Common  Stock,  $.01 par  value  per  share,  as  authorized  on the date of the
Agreement,  (b) any  other  capital  stock  of any  class  or  classes  (however
designated)  of the Company,  authorized  on or after such date,  the holders of
which shall have the right, without limitation as to amount, either to all or to
a share of the balance of current dividends and liquidating  dividends after the
payment of dividends and distributions on any shares entitled to preference, and
the  holders of which shall  ordinarily,  in the  absence of  contingencies,  be
entitled  to vote for the  election of a majority  of  directors  of the Company
(even though the right so

                                      -26-


<PAGE>


to vote has been suspended by the happening of such a  contingency)  and (c) any
other securities into which or for which any of the securities  described in (a)
or (b) may be  converted or  exchanged  pursuant to a plan of  recapitalization,
reorganization, merger, sale of assets or otherwise.

                      (c) The term "Other Securities" refers to any stock (other
than  Common  Stock) and other  securities  of the  Company or any other  person
(corporate or otherwise)  which the holders of the Warrants at any time shall be
entitled to receive, or shall have received, on the exercise of the Warrants, in
lieu of or in addition to Common  Stock,  or which at any time shall be issuable
or shall have been issued in exchange for or in  replacement  of Common Stock or
Other Securities pursuant to Section 5 or otherwise.

         1.   Exercise of Warrant.

              1.1. Full  Exercise.  This Warrant may be exercised in full by the
holder hereof by surrender of this Warrant, with the form of subscription at the
end hereof duly executed by such holder,  to the Company at its principal office
in the  Commonwealth  of  Massachusetts,  accompanied by payment,  in cash or by
certified or official  bank check  payable to the order of the  Company,  in the
amount  obtained  by  multiplying  (a) the number of shares of Common  Stock for
which this Warrant is then exercisable by (b) the Purchase Price then in effect.

              1.2.  Partial  Exercise.  This Warrant may be exercised in part by
surrender of this Warrant in the manner and at the place  provided in subsection
1.1 except that the amount payable by the holder on such partial  exercise shall
be the amount  obtained by multiplying  (a) the number of shares of Common Stock
designated  by the holder in the form of  subscription  at the end hereof by (b)
the Purchase Price then in effect.  On any such partial  exercise the Company at
its expense will forthwith  issue and deliver to or upon the order of the holder
hereof a new Warrant or Warrants of like tenor, in the name of the holder hereof
or as such holder (upon payment by such holder of any applicable transfer taxes)
may  request,  calling  in the  aggregate  on the face or faces  thereof for the
number of shares of Common Stock for which such Warrant or Warrants may still be
exercised.

              1.3.  Payment  by Notes  Surrender.  Notwithstanding  the  payment
provisions  of  subsections  1.1 and 1.2,  all or part of the  payment  due upon
exercise of this Warrant in full or in part may be made by the surrender by such
holder to the  Company of any of the  Company's  Notes  issued  pursuant  to the
Agreement and such Notes so surrendered  shall be credited  against such payment
in an amount equal to the principal  amount thereof and accrued  interest to the
date of surrender.

              1.4. Company Acknowledgment.  The Company will, at the time of the
exercise of the Warrant,  upon the request of the holder hereof,  acknowledge in
writing its continuing obligation to

                                      -27-


<PAGE>


afford to such  holder any  rights to which such  holder  shall  continue  to be
entitled after such exercise in accordance  with the provisions of this Warrant.
If the holder shall fail to make any such request, such failure shall not affect
the  continuing  obligation  of the  Company  to afford to such  holder any such
rights.

              1.5.  Trustee  for  Warrant  Holders.  in the event that a bank or
trust  company  shall  have been  appointed  as trustee  for the  holders of the
Warrants  pursuant to subsection  4.2, such bank or trust company shall have all
the powers and duties of a warrant  agent  appointed  pursuant to Section 12 and
shall accept,  in its own name for the account of the Company or such  successor
person as may be entitled thereto,  all amounts otherwise payable to the Company
or such successor,  as the case may be, on exercise of this Warrant  pursuant to
this Section 1.

              1.6. Shareholder Agreement as Condition to Exercise.  If, upon any
full or partial exercise of this Warrant,  eighty-five  percent (85%) or greater
of the  shares of Common  Stock of the  company  are  subject  to a  shareholder
agreement  between the  Company  and the owners of such shares of Common  Stock,
then as a condition to exercise of this Warrant the holder hereof shall become a
party to such shareholder agreement and shall be subject to all of the terms and
conditions therein.

         2.   Delivery  of Stock  Certificates,  etc., on  Exercise.  As soon as
practicable  after the exercise of this  Warrant in full or in part,  and in any
event within ten (10) days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder  hereof,  or as such holder (upon payment by such
holder  of  any  applicable   transfer  taxes)  may  direct,  a  certificate  or
certificates  for the  number of fully paid and  nonassessable  shares of Common
Stock (or Other  Securities)  to which such  holder  shall be  entitled  on such
exercise,  plus,  in lieu of any  fractional  share to which such  holder  would
otherwise  be  entitled,  cash  equal to such  fraction  multiplied  by the then
current  market value of one full share,  together with any other stock or other
securities and property  (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

         3.   Adjustment  for   Dividends  in  Other  Stock,   Property,   etc.;
Reclassification,  etc. In case at any time or from time to time, the holders of
Common  Stock (or Other  Securities)  shall have  received,  or (on or after the
record date fixed for the  determination  of  shareholders  eligible to receive)
shall have become entitled to receive, without payment therefor,

                      (a)  other or  additional  stock or  other  securities  or
property (other than cash) by way of dividend, or

                      (b) any cash (excluding cash dividends  payable solely out
of earnings or earned surplus of the Company), or

                                      -28-


<PAGE>


                      (c)  other or  additional  stock or  other  securities  or
property  (including  cash)  by way  of  spin-off,  split-up,  reclassification,
recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other  Securities)  issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in subsection  5.4),  then and in each such case the holder of this Warrant,
on the  exercise  hereof as  provided in Section 1, shall be entitled to receive
the amount of stock and other  securities  and property  (including  cash in the
cases  referred  to in  subdivisions  (b) and (c) of this  Section 3) which such
holder would hold on the date of such exercise if on the date hereof he had been
the holder of record of the number of shares of Common  Stock  called for on the
face of this Warrant and had thereafter,  during the period from the date hereof
to and  including the date of such  exercise,  retained such shares and all such
other or additional stock and other  securities and property  (including cash in
the cases referred to in subdivisions  (b) and (c) of this Section 3) receivable
by him as aforesaid during such period,  giving effect to all adjustments called
for during such period by Sections 4 and 5.

         4. Adjustment for Reorganization, Consolidation, Merger, etc.

         4.1. In case at any time or from time to time,  the  Company  shall (a)
effect a reorganization, (b) consolidate with or merge into any other person, or
(c) transfer all or  substantially  all of its properties or assets to any other
person  under  any plan or  arrangement  contemplating  the  dissolution  of the
Company,  then,  and in each  such  case,  the  holder of this  Warrant,  on the
exercise  hereof as provided in Section 1 at any time after the  consummation of
such  reorganization,  consolidation  or  merger  or the  authorization  of such
dissolution (but in no event later than thirty (30) days following the effective
date of such  dissolution),  as the case may be, shall  receive,  in lieu of the
Common  Stock (or Other  Securities)  issuable  on such  exercise  prior to such
consummation or such effective date, the stock and other securities and property
(including  cash) to which  such  holder  would  have  been  entitled  upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant,  immediately prior thereto, all subject to
further adjustment thereafter as provided in Sections 3 and 5.

         4.2.  Dissolution.  In the  event  of any  dissolution  of the  Company
following the transfer of all or substantially  all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property  (including cash, where
applicable)  receivable by the holders of the Warrants  after the effective date
of such dissolution pursuant to this Section 4 to a

                                      -29-



<PAGE>


bank or trust company having an office in Boston or Worcester, Massachusetts, as
trustee for the holder or holders of the Warrants.

         4.3.  Continuation of Terms.  Upon any  reorganization,  consolidation,
merger or transfer (and any dissolution  following any transfer)  referred to in
this  Section 4, this  Warrant  shall  continue in full force and effect and the
terms hereof shall be applicable to the shares of stock and other securities and
property  receivable on the exercise of this Warrant after the  consummation  of
such   reorganization,   consolidation  or  merger  or  the  effective  date  of
dissolution  following  any such  transfer,  as the case  may be,  and  shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer,  the person acquiring all or substantially all of the
properties  or assets of the  Company,  whether  or not such  person  shall have
expressly assumed the terms of this Warrant as provided in Section 6.

         5.  Adjustment  for  Issue or Sale of  Common  Stock  at Less  Than The
Purchase Price in Effect.

         5.1.  General.  If the Company  shall at any time or from time to time,
issue any  additional  shares of Common Stock (other than shares of Common Stock
excepted  from the  provisions  of this  Section  5 by  subsections  5.4 or 5.5)
without  consideration  or for a net  consideration  per  share  less  than  the
Purchase Price in effect  immediately prior to such issuance,  then, and in each
such case:  (a) the Purchase  Price shall be lowered to an amount  determined by
multiplying such Purchase Price then in effect by a fraction:

                      (1) the  numerator  of which  shall be (a) the  number  of
shares of Common  Stock  outstanding  immediately  prior to the issuance of such
additional shares of Common Stock, plus (b) the number of shares of Common Stock
which the net aggregate  consideration,  if any, received by the Company for the
total number of such additional  shares of Common Stock so issued would purchase
at the Purchase Price in effect immediately prior to such issuance, and

                      (2) the  denominator  of which  shall be (a) the number of
shares of Common  Stock  outstanding  immediately  prior to the issuance of such
additional  shares of Common Stock plus (b) the number of such additional shares
of Common Stock so issued;

and (b) the holder of this Warrant shall  thereafter,  on the exercise hereof as
provided  in Section 1, be  entitled  to receive  the number of shares of Common
Stock-determined by multiplying the number of shares of Common Stock which would
otherwise  (but for the provisions of this  subsection  5.1) be issuable on such
exercise by the fraction of which (i) the numerator is the

                                      -30-


<PAGE>


Purchase Price which would  otherwise (but for the provisions of this subsection
5.1) be in effect,  and (ii) the  denominator is the Purchase Price in effect on
the date of such exercise.

         5.2. Definitions, etc. For purposes of this Section 5 and of Section 7:

         The issuance of any warrants, options or other subscription or purchase
     rights  with  respect  to shares of Common  Stock and the  issuance  of any
     securities  convertible into or exchangeable for shares of Common Stock (or
     the issuance of any warrants,  options or other rights with respect to such
     convertible or exchangeable securities) shall be deemed an issuance at such
     time of such Common Stock if the Net  Consideration  Per Share which may be
     received by the Company for such Common Stock (as  hereinafter  determined)
     shall be less than the  Purchase  Price at the time of such  issuance  and,
     except as hereinafter provided, an adjustment in the Purchase Price and the
     number of shares of Common  Stock  issuable  upon  exercise of this Warrant
     shall be made upon each such issuance in the manner  provided in subsection
     5.1. Any obligation,  agreement or undertaking to issue warrants,  options,
     or other subscription or purchase rights at any time in the future shall be
     deemed  to be an  issuance  at  the  time  such  obligation,  agreement  or
     undertaking is made or arises.  No adjustment of the Purchase Price and the
     number of shares of Common  Stock  issuable  upon  exercise of this Warrant
     shall be made  under  subsection  5.1 upon the  issuance  of any  shares of
     Common  Stock which are issued  pursuant to the  exercise of any  warrants,
     options  or other  subscription  or  purchase  rights  or  pursuant  to the
     exercise of any conversion or exchange rights in any convertible securities
     if any adjustment  shall previously have been made upon the issuance of any
     such  warrants,  options  or  other  rights  or upon  the  issuance  of any
     convertible  securities  (or upon the issuance of any warrants,  options or
     other rights  therefor) as above  provided.  Any adjustment of the Purchase
     Price and the number of shares of Common Stock  issuable  upon  exercise of
     this Warrant with respect to this subsection 5.2 which relates to warrants,
     options or other  subscription or purchase rights with respect to shares of
     Common Stock shall be  disregarded  if, as, and when all of such  warrants,
     options or other  subscription  or purchase  rights expire or are cancelled
     without being exercised,  so that the Purchase Price effective  immediately
     upon such  cancellation or expiration  shall be equal to the Purchase Price
     in effect at the time of the issuance of the expired or cancelled warrants,
     options or other  subscriptions  or purchase  rights,  with such additional
     adjustments  as would have been made to that Purchase Price had the expired
     or cancelled  warrants,  options or other  subscriptions or purchase rights
     not  been  issued.   For  purposes  of  this   subsection   5.2,  the  "Net
     Consideration  Per Share"  which may be received  by the  Company  shall be
     determined as follows:

                                      -31-


<PAGE>


                      (A) The  "Net  Consideration  Per  Share"  shall  mean the
         amount equal to the total amount of consideration,  if any, received by
         the Company for the issuance of such warrants, options,  subscriptions,
         or other purchase  rights or convertible  or  exchangeable  securities,
         plus the  minimum  amount  of  consideration,  if any,  payable  to the
         Company upon exercise or conversion  thereof,  divided by the aggregate
         number  of  shares of  Common  Stock  that  would be issued if all such
         warrants,   options,   subscriptions,   or  other  purchase  rights  or
         convertible or exchangeable  securities  were  exercised,  exchanged or
         converted.

                      (B)  The  "Net  Consideration  Per  Share"  which  may  be
         received by the Company  shall be determined in each instance as of the
         date of issuance of warrants, options,  subscriptions or other purchase
         rights, or convertible or exchangeable securities without giving effect
         to any possible future price  adjustments or rate adjustments which may
         be applicable with respect to such warrants, options,  subscriptions or
         other purchase rights or convertible securities.

     For  purposes  of this  Section  5,  if a part or all of the  consideration
     received by the Company in  connection  with the  issuance of shares of the
     Common  Stock or the  issuance of any of the  securities  described in this
     Section 5, consists of property other than cash, such  consideration  shall
     be deemed to have the same  value as shall be  determined  in good faith by
     the Board of Directors of the Company.

         This  subsection  5.2 shall not  apply  under any of the  circumstances
described in subsection 5.4.

         5.3. Dilution in Case of Other Securities. In case any Other Securities
shall be issued or sold, or shall become subject to issue upon the conversion or
exchange of any stock (or Other  Securities) of the Company (or any other issuer
of  other  Securities  or any  other  person  referred  to in  Section  4) or to
subscription,  purchase or other  acquisition  pursuant to any rights or options
granted by the Company (or such other issuer or person), for a consideration per
share such as to dilute the  purchase  rights  evidenced  by this  warrant,  the
computations,  adjustments and readjustments provided for in this Section 5 with
respect to the Purchase  Price and the number of shares of Common Stock issuable
upon  exercise of this Warrant shall be made as nearly as possible in the manner
so provided and applied to determine the amount of Other Securities from time to
time receivable on the exercise of the Warrants, so as to protect the holders of
the Warrants against the effect of such dilution.

         5.4.  Extraordinary  Events.  In the event that the  Company  shall (i)
issue additional shares of the Common Stock as a dividend or other  distribution
on outstanding  Common Stock,  (ii) subdivide its  outstanding  shares of Common
Stock, or (iii) combine

                                      -32-


<PAGE>


its  outstanding  shares of the Common Stock into a smaller  number of shares of
the  Common  Stock,  then,  in  each  such  event,  the  Purchase  Price  shall,
simultaneously  with the happening of such event, be adjusted by multiplying the
then Purchase Price by a fraction, the numerator of which shall be the number of
shares of  Common  Stock  outstanding  immediately  prior to such  event and the
denominator  of which shall be the number of shares of Common Stock  outstanding
immediately  after such event,  and the product so obtained shall  thereafter be
the Purchase Price then in effect. The Purchase Price, as so adjusted,  shall be
readjusted  in the same manner upon the  happening  of any  successive  event or
events described herein in this subsection 5.4. The holder of this Warrant shall
thereafter,  on the  exercise  hereof as  provided  in Section 1, be entitled to
receive  that number of shares of Common Stock  determined  by  multiplying  the
number of shares of Common Stock which would  otherwise  (but for the provisions
of this  subsection 5.4) be issuable on such exercise by a fraction of which (i)
the  numerator  is the  Purchase  Price  which  would  otherwise  (but  for  the
provisions of this subsection 5.4) be in effect, and (ii) the denominator is the
Purchase Price in effect on the date of such exercise.

         5.5.  Excluded  Shares.  Section 5.1 shall not apply to the issuance of
shares  of Common  Stock,  or  options  therefor,  to  directors,  officers  and
employees of the Company  pursuant to any stock options,  stock purchase,  stock
ownership or  compensation  plan approved by the  Company's  Board of Directors,
provided that the aggregate number of shares,  and options  therefor  (including
options  outstanding on the date hereof),  so issued to directors,  officers and
employees does not exceed 150,000 shares.

         6. No Dilution or Impairment. The Company will not, by amendment of its
Articles  of  Organization  or through any  reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of the  Warrants,  but will at all times in good  faith  assist in the
carrying  out of all such terms and in the  taking of all such  action as may be
necessary  or  appropriate  in order to protect the rights of the holders of the
Warrants against dilution or other  impairment.  Without limiting the generality
of the foregoing,  the Company (a) will not increase the par value of any shares
of stock  receivable  on the exercise of the Warrants  above the amount  payable
therefor on such exercise,  (b) will take all such action as may be necessary or
appropriate  in order that the Company may validly and legally  issue fully paid
and  nonassessable  shares of stock on the exercise of all Warrants from time to
time  outstanding,  (c) will not issue any  capital  stock of any class which is
preferred as to dividends or as to the distribution of assets upon  voluntary or
involuntary  dissolution,  liquidation  or winding up,  unless the rights of the
holders  thereof  shall be limited to a fixed sum or  percentage of par value in
respect of  participation  in dividends and in any such  distribution of assets,
and (d) will not transfer all or substantially  all of its properties and assets
to any other person

                                      -33-


<PAGE>


(corporate or otherwise),  or consolidate with or merge into any other person or
permit any such  person to  consolidate  with or merge into the  Company (if the
Company is not the surviving  person),  unless such other person shall expressly
assume in writing and will be bound by all the terms of the Warrants.

         7.  Accountants'  Certificate  as to  Adjustments.  In each case of any
adjustment or readjustment  in the shares of Common Stock (or Other  Securities)
issuable on the  exercise  of the  Warrants,  the  Company at its  expense  will
promptly cause independent  certified public accountants of recognized  standing
selected by the Company to compute such adjustment or readjustment in accordance
with the terms of the  Warrants  and prepare a  certificate  setting  forth such
adjustment  or  readjustment  and  showing  in detail  the facts upon which such
adjustment  or  readjustment  is  based,   including  a  statement  of  (a)  the
consideration received or receivable by the Company for any additional shares of
Common Stock (or Other Securities)  issued or sold or deemed to have been issued
or sold,  (b) the  number  of shares  of  Common  Stock  (or  Other  Securities)
outstanding  or deemed to be  outstanding,  and (c) the  Purchase  Price and the
number of shares of Common Stock to be received  upon  exercise of this Warrant,
in effect immediately prior to such issue or sale and as adjusted and readjusted
as provided in this Warrant. The Company will forthwith mail a copy of each such
certificate to each holder of a Warrant, and will, on the written request at any
time of any  holder of a  Warrant,  furnish  to such  holder a like  certificate
setting  forth the  Purchase  Price at the time in effect and showing how it was
calculated.

         8. Notices of Record Date, etc. In the event of

                      (a) any taking by the  Company of a record of the  holders
         of any class or securities for the purpose of  determining  the holders
         thereof who are entitled to receive any dividend or other distribution,
         or any rightto  subscribe for, purchase or otherwise acquire any shares
         of stock of any  class  or any  other  securities  or  property,  or to
         receive any other right, or

                      (b)  any  capital   reorganization  of  the  Company,  any
         reclassification  or  recapitalization  of  the  capital  stock  of the
         Company or any transfer of all or  substantially  all the assets of the
         Company to or  consolidation  or merger of the Company with or into any
         other person, or

                      (c) any voluntary or involuntary dissolution,  liquidation
         or winding-up of the Company, or

                      (d) any  proposed  issue or grant  by the  Company  of any
         shares of stock of any class or any other  securities,  or any right or
         option to subscribe  for,  purchase or otherwise  acquire any shares of
         stock of any class or any other

                                      -34-


<PAGE>


         securities  (other than with respect to the Excluded Shares referred to
         in subsection  5.5 and the issue of Common Stock on the exercise of the
         Warrants),

then and in each such event the Company  will mail or cause to be mailed to each
holder of a Warrant a  notice  specifying  (i) the date on which any such record
is to be taken for the  purpose of such  dividend,  distribution  or right,  and
stating the amount and character of such dividend,  distribution or right,  (ii)
the date on which any such reorganization,  reclassification,  recapitalization,
transfer,  consolidation,  merger, dissolution,  liquidation or winding-up is to
take  place,  and the time,  if any is to be fixed,  as of which the  holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or Other  Securities)  for  securities or other property
deliverable   on  such   reorganization,   reclassification,   recapitalization,
transfer,  consolidation,  merger,  dissolution,  liquidation or winding-up, and
(iii) the amount and  character of any stock or other  securities,  or rights or
options with respect thereto, proposed to be issued or granted, the date of such
proposed  issue or grant  and the  persons  or class  of  persons  to whom  such
proposed issue or grant is to be offered or made. Such notice shall be mailed at
least  twenty (20) days prior to the date  specified in such notice on which any
such action is to be taken.

         9. Reservation of Stock,  etc.,  Issuable on Exercise of Warrants.  The
Company will at all times  reserve and keep  available,  solely for issuance and
delivery on the exercise of the  Warrants,  all shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrants.

         10.  Exchange of Warrants.  On  surrender  for exchange of any Warrant,
properly  endorsed,  to the  Company,  the Company at its expense will issue and
deliver to or on the order of the holder  thereof a new  Warrant or  Warrants of
like  tenor,  in the name of such  holder or as such  holder (on payment by such
holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

         11.  Replacement  of  Warrants.   On  receipt  of  evidence  reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss,  theft or destruction of any Warrant,
on delivery of an indemnity  agreement or security  reasonably  satisfactory  in
form and  amount  to the  Company  or,  in the case of any such  mutilation,  on
surrender  and  cancellation  of such  Warrant,  the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

         12. Warrant Agent. The Company may, by written notice to each holder of
a Warrant,  appoint  an agent  having an office in either  Boston or  Worcester,
Massachusetts  for the purpose of issuing Common Stock (or Other  Securities) on
the exercise of the

                                      -35-


<PAGE>


Warrants pursuant to Section 1, exchanging  Warrants pursuant to Section 10, and
replacing  Warrants  pursuant  to  Section  11,  or any of  the  foregoing,  and
thereafter any such issuance, exchange or replacement, as the case may be, shall
be made at such office by such agent.

         13.  Remedies.  The Company  stipulates that the remedies at law of the
holder of this Warrant in the event of any default or threatened  default by the
Company  in the  performance  of or  compliance  with  any of the  terms of this
Warrant  are  not  and  will  not  be  adequate,  and  that  such  terms  may be
specifically  enforced by a decree for the specific performance of any agreement
contained  herein or by an  injunction  against a violation  of any of the terms
hereof or otherwise.

         14.  Negotiability,  etc.  This  Warrant is issued  upon the  following
terms, to all of which each holder or owner hereof by the taking hereof consents
and agrees:

                      (a)  title  to  this   Warrant  may  be   transferred   by
         endorsement  (by the holder hereof  executing the form of assignment at
         the end  hereof)  and  delivery  in the same manner as in the case of a
         negotiable instrument transferable by endorsement and delivery;

                      (b) any  person in  possession  of this  Warrant  properly
         endorsed is  authorized to represent  himself as absolute  owner hereof
         and is empowered to transfer  absolute title hereto by endorsement  and
         delivery hereof to a bona fide purchaser  hereof for value;  each prior
         taker or owner  waives and  renounces  all of his equities or rights in
         this Warrant in favor of each such bona fide  purchaser,  and each such
         bona fide  purchaser  shall  acquire  absolute  title hereto and to all
         rights represented hereby; and

                      (c) until this Warrant is  transferred on the books of the
         Company,  the Company  may treat the  registered  holder  hereof as the
         absolute owner hereof for all purposes,  notwithstanding  any notice to
         the contrary.

         15. Notices, etc. All notices and other communications from the Company
to the  holder of this  Warrant  shall be mailed by first  class  registered  or
certified mail,  postage prepaid,  at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an  address,  then to, and at the  address  of, the last  holder of this
Warrant who has so furnished an address to the Company.

         16.  Miscellaneous.  This  Warrant  and any term hereof may be changed,
waived, discharged or terminated  only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought.  This Warrant shall be construed and enforced in accordance  with and
governed by the laws of the Commonwealth of Massachusetts.  The headings in this
Warrant are for purposes of reference only, and shall not

                                      -36-

limit or  otherwise  affect  any of the  terms  hereof.  This  Warrant  is being
executed as an instrument under seal. The invalidity or  unenforceability of any
provision  hereof shall in no way affect the validity or  enforceability  of any
other provision.

         17. Expiration. The right to exercise this Warrant shall expire at 5:00
P.M.,  local time at the place where the then principal office of the Company is

                            Patent License Agreement

         THIS  AGREEMENT  is made  effective  as of 5/30/95 by and between  John
Wilbur Hicks ("Hicks") of 312 Howard Street, Northborough,  MA 01532 and Optical
Corporation of America,  a Massachusetts  Corporation having a place of business
at 170 Locke Drive ("OCA"). Marlborough, MA 01782.

         Hicks is the owner of U.S. Patent 4,768,849, which was granted to Hicks
by the U.S. Patent and Trademark Office on September 6, 1988, and  corresponding
foreign  patent(s) and  application(s)  (collectively  referred to herein as the
"Patent").  In accordance with an agreement between Hicks and OCA dated February
21, 1995 (the "Prior Agreement"),  and in consideration of the mutual agreements
set forth here, Hicks and OCA agree as follows:

LICENSE GRANT

1.       Hicks hereby grants and agrees to grant to OCA a world-wide irrevocable
license, with a right to sub-license, to make, have  made, use and sell products
which are  covered by any valid and  subsisting  claim(s)  of the  Patent.  Such
license is exclusive  except that with respect to products  which are covered by
any valid and  subsisting  claim(s)  of the  Patent  and which  involve  optical
wavelenghs which are less than equal to 1.1u:
         (a)       Hicks retains the right to make, have made, use and sell such
                   products: and
         (b)       OCA  shall  sell  such  products  only to  Hicks unless Hicks
                   consents otherwise in writing.

2.       Hicks  warrants and  represents  that no  continuation,  divisional  or
continuation-in-part  applications  based on U.S.  General  No.  907,622,  filed
September  15, 1988 (the patent  application  from which U.S.  Patent  4,768,849
issued) have been filed in the U.S.  Patent and Trademark  Office.  Furthermore,
with respect to products  which are within the scope of any claim of the Patent,
Hicks  shall not assert  against  OCA or its  sub-licensees,  or the  customers,
agents,  partners or  suppliers  of OCA or any  sub-licensee,  any  intellectual
property,  including but not limited to any patents,  which Hicks currently owns
or may acquire during the term of this Agreement.  Hicks shall not assign to any
third party or otherwise  dispose of any such  intellectual  property  except in
conjunction with an obligation on the assignee of such intellectual  property to
be bound by the non-assertion obligation of this Paragraph.

3.       Hicks shall  maintain  the Patent in force for its maximum  permissible
time duration by timely payment of all maintenance fees,  annuities or the like.
Hicks may at any time during the term of this Agreement be discharged  from this
obligation to pay maintenance fees, annuities or the like, by offering to assign
to OCA title to and all his  rights in the  Patent  (including  the U.S.  patent
and/or any or all corresponding  foreign patent(s) and  application(s),  without
further consideration,  not less than three (3) months prior to the due date for
the next due maintenance fee,  annuity or the like. Any  such  assignment  shall
not negate or terminate the non-assertion  obligation of Paragraph 2, above, but
shall remove the assigned  patent(s)  (meaning whichever one or more of the U.S.
and corresponding  foreign patent(s) and  application(s) are assigned to OCA) as
the basis for the royalty obligation of Paragraph 4, below.

                                       1
<PAGE>

PAYMENT AND ACCOUNTING

4.       OCA shall pay to Hicks a royalty of two  percent  (2%) of the net sales
price of the products  covered by any valid and  subsisting  claim of the Patent
licensed under this Agreement, except such products as are sold to Hicks. Only a
single royalty payment shall be payable  pursuant to this Agreement with respect
to any one product,  not withstanding  that it may be made, sold,  resold and/or
used in multiple  countries in which is covered by a valid and subsisting  claim
of the Patent.

5.       Within  forty-five (45) days of the end of each calendar  quarter,  OCA
shall provide to Hicks:
         (a)   a quarterly royalty statement, in writing, which contains (i) the
               quantity  of the  licensed  products  which were sold  during the
               prior  calendar  quarter and for which  revenues were received by
               OCA, and (ii) the total net sales price received for the products
               of subparagraph 5(a)(i); and
         (b)   a royalty  payment  calculated in accordance with Paragraph 4 and
               subject  to the  Consulting  Fee  offset  recited  in  the  third
               paragraph of Section D of the Prior Agreement.

6.       Within  ninety (90) days of the end of each  calendar  year,  OCA shall
provide  to  Hicks,  in  writing,  an annual  royalty  statement,  prepared  and
certified by OCA's certified public accountants, which contains (i) the quantity
of products licensed under Paragraph 1 which were sold during the prior calendar
year and for which  revenues  were received by OCA, and (ii) the total net sales
price received by OCA for such products.

TERM AND TERMINATION

7.       The term of this  Agreement  shall  extend from the date first  written
above to the date of expiration of the Patent.

ENFORCEMENT AND SUB-LICENSING

8.       OCA shall have the exclusive  right to enforce the Patent against third
parties for infringement of Patent,  and shall have the right,  unless otherwise
waived  by OCA in  writing,  to  control  the  defense  of  the  Patent  against
invalidity  or  unenforceability  claims  brought by a third party in any court,
patent office, or any other judicial or administrative tribunal.

9.       Hicks  shall  provide  any  necessary   non-monetary   support  to  OCA
reasonably  required for enforcement or defense as set forth in Paragraph 8, and
Hicks  shall  allow OCA to  intervene,  to the extent  permitted  by law, in any
action involving the Patent in which Hicks is a named party.

10.      OCA shall bear its costs in any  enforcement or defense as set forth in

incurred at OCA's request for work related to such enforcement or defense.

                                       2
<PAGE>

11.      In the event that OCA grants a sub-license under the Patent,  OCA shall
pay to Hicks 15% of all monetary  revenues received by OCA for such sub-license.
In the event that any enforcement or defense as set forth in Paragraph 8 results
in any type of  monetary  award paid to OCA,  OCA shall pay to Hicks 15% of such
award,  after  subtracting all costs and expenses,  including but not limited to
attorney's fees, incurred by OCA in enforcement or defense of the Patent.

OTHER 

12.      Any  controversy  or claim arising  under or related to this  Agreement
shall be resolved by good faith negotiations  between the parties.  In the event
that any controversy or claim cannot be resolved after good faith  negotiations,
the sole remedy shall be resolution of such  controversy or claim by arbitration
held in  Marlborough,  Massachusetts  (or such other location as the parties may
mutually select at that time) before a single  arbitrator in accordance with the
commercial rules of the American Arbitration Association.

13.      This  Agreement  is binding  upon and shall inure to the benefit of the
parties hereto and their repective successors and assigns.

14.      This  Agreement,  taken together  with the Prior Agreement, constitutes
the entire agreement  between the parties with respect to the subject matter set
forth above.  To the extent that this  Agreement  and the Prior  Agreeement  are
inconsistent or in conflict, this Agreement shall control.

         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as

         John D. Viggiano                              John Wilbur Hicks
         Its Vice-President

                                       3


                                   AGREEMENT

         THIS  AGREEMENT  dated as of February  21, 1995 is between  John Wilbur
Hicks  ("Hicks")  of 312  Howard  Street,  Northborough,  MA 01532  and  Optical
Corporation of America,  a Massachusetts  corporation  ("CCA") having a place of
business at 170 Locke Drive,  Marlborough,  MA 01752.  In  consideration  of the
mutual agreements set forth herein, Hicks and OCA agree as follows:

A.       Consulation and Cooperation.

         During the Term of this  Agreement,  Hicks will advise and consult with
         OCA in the following  Field of  Cooperation,  namely the application of
         thin-film coating technology  available to OCA to the production by OCA
         of components and products  incorporating  those  components  useful in
         fiber-optic systems ("Products").

         OCA recognizes that Hicks is developing overall fiber-optic systems for
         information  distribution  to and  from  multiple  users.  The  parties
         recognize  that  OCA  product   development   and  design  may  require
         discussion and consideration with Hicks of overall systems  performance
         requirements.  However,  nothing  in this  Agreement  will give OCA any
         rights (i) to require Hicks to provide his proprietary  overall systems
         know-how  to third  parties  on OCA's  behalf,  or (ii) to any share of
         compensation  which  Hicks  may  receive  from  third  parties  for the
         provision of such overall systems  know-how and design which is outside
         the scope of the services Hicks will provide OCA under this  Agreement.
         OCA will not require  that  thin-film  devices be used or  specified by
         Hicks in such systems. Hicks will not require OCA to provide Hicks, his
         Affiliates or licensees, with products conceived of or developed by OCA
         during the Term of this Agreement or under license to OCA from Hicks or
         his Affiliates.

B.       Contact Within OCA

         Until further  notice,  OCA has designated  Michael A Scobey,  its Vice
         President, to act on its behalf for the purposes of this Agreement.

C.       Term and Compensation

         Hicks will provide advisory and consulting services to OCA in the Field
         of  Cooperation  for a period of five (5)  years  from the date of this
         Agreement.

         As  compensation  for such  services,  OCA will pay  Hicks a fee of Six
         Thousand  Dollars  ($6,000.00)  upon  execution of this Agreement and a
         further fee of Eighteen Thousand Dollars ($18,000.00) per year for each
         year of the Term payable in equal monthly installments (the "Consulting
         Fee").

         For each year of the Term after the first,  the Consulting Fee shall be
         adjusted,  upwards or downwards, as the case may be, by multiplying the
         Consulting  Fee paid for the prior year by the  percentage  increase or
         decrease as the case may be, in the  Consumer  Price  index  during the
         course of such prior year. For the purposes hereof, the term
<PAGE>

         "Consumer  Price Index" refers to the "Consumer Price Index All Cities"
         published by the Bureau of Labor Statistics,  U.S. Department of Labor,
         during such prior year (or its generally recognized successor index).

D.       OCA's Rights to License Technology of Hicks and Affiliates

         Upon written request by OCA, Hicks will license U.S. Patent  #4,768,849
         (the  "Patent")  to OCA with the  exclusive  right to  produce  or have
         produced  Products  covered by the Patent  for  applications  involving
         Optical  wavelengths which are greater than 1.1u for the remaining life
         of the Patent. OCA may produce or have produced Products covered by the
         Patent for  applications  involving  Optical  wavelenghs which are less
         than 1.1u but only for sale to Hicks or a designated affiliate,  unless
         Hicks  shall  otherwise  consent in writing.  Hicks shall not  purchase
         Products  covered  by the  Patent for  applications  involving  optical
         wavelengths  which  are less than  1.1u  from a source  other  than OCA
         without first haven given OCA the  opportunity to propose to build such
         Product  for Hicks at a  competitive  price.  If OCA elects not to make
         such a proposal or if Hicks  purchases such Product from a source other
         than OCA, Hicks or an affiliate shall pay OCA a royalty of five percent
         (5%) of the net sales of such Product.

         As  compensation  for all the rights of use  described in the preceding
         paragraph,  OCA will pay to or on the  direction  of  Hicks,  or to his
         designated Affiliate, a royalty of two percent (2%) of the net sales of
         the Product.

         Commencing with the second year of the Term, one-half of the Consulting
         Fee paid to Hicks by OCA pursuant to the foregoing  Paragraph C will be
         considered to be payment pro tanto of any royalties due Hicks  pursuant
         to  this   Paragraph  D  from  Products  sales  by  OCA  (the  "Running
         Royalties")  but in any year,  Hicks  will  receive  no less than fifty
         percent  (50%) of the  Consulting  Fee plus fifty  percent (50%) of the
         Running  Royalty.  Should Hicks decide not to obtain or maintain patent
         coverage for  Products,  or  technologies  falling  within the Field of
         Cooperation,   Hicks  will  give  OCA  prompt  written  notice  of  his
         intentions  and OCA will be free  thereafter  to pursue or maintain the
         coverage OCA's expense and Hicks will assign such patent to OCA.

E.       Other  Patents  Obtained  by OCA or  Hicks  During  the  Term  of  this
         Agreement

         During the term of  this Agreement Product concepts within the Field of
         Cooperation  will be  disclosed  by Hicks to OCA and, OCA will have six
         (6) months in which to decide if it will seek patent protection for the
         inventions which  incorporate the concepts.  Should OCA decline,  Hicks
         will  be  free  to  pursue  coverage  at  Hicks'  expense.   Except  as
         hereinafter provided, no additional compensation will be due Hicks from
         OCA or due OCA from Hicks for use of such patents.

         Hicks will provide any necessary non-monetary support to OCA reasonably
         required for the  preparation,  submission  and  prosecution of patents
         initially  prepared  during  the  Term  of  this  Agreement.  OCA  will
         reimburse  Hicks for travel and incidental  expenses  incurred at OCA's
         request for patent related work.

                                       2
<PAGE>

         If OCA  elects  to seek  patent  protection  for the  inventions  which
         incorporate the Product concepts within the Field of Cooperation  which
         are disclosed by Hicks to OCA, but thereafter chooses not to produce or
         have produced Products covered by such patents,  upon request by Hicks,
         OCA will  grant to Hicks or an  Affiliate  the right to produce or have
         produced  Products  covered by such patents for the  remaining  life of
         such Patents. For such rights, if exercised, Hicks or an Affiliate will
         pay OCA a royalty of twelve (12%) of the net sales of the Products.

F.       Discontinuance: Defense Expense

         In either case, once the original patent holder, applicant or assignee,
         having given due notice to the other party, discontinues prosecution or
         maintenance,  no royalty  will be due for Products  produced  under the
         abandoned coverage.

         The burden of  defense  and the  litigation  expenses  associated  with
         defense of patents will be first borne by the party  holding the patent
         or applying for patent  coverage  and each such party herein  agrees to
         carry out such defense with dilligence. However, should either Hicks or
         OCA anticipate  costs or difficulties  such that they cannot  prudently
         proceed with defense, each agrees to advise the other in timely fashion
         so that the  other can opt to  proceed  with  defense.  In such a case,
         future  royalties due under licese of the challenged  patent or patents
         will first be applied to the costs of defense.

G.       Confidentiality

         OCA has attached to this letter the  Confidentiality and Non-Disclosure
         Agreement with Hicks dated September 16, 1994 (the  "Attachment"),  the
         terms and provisions of which are incorporated herein by reference.

H.       General

         This  Agreement  is binding upon and shall inure  to the benefit of the
         parties hereto and their respective  successors and assigns, as well as
         any Affiliate of either party.  For the purposes of this  Agreement the
         term  "Affiliate"  shall mean any  individual who is related to a party
         and any other person, firm or corporation which controls, is controlled
         by, or is under common control with either party to this Agreement.

         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as
an instrument under seal all as of the day and year first above written.

distribution  of the process of the  collateral  following  default,  whether by
reason of liquidation, bankruptcy, arrangement, receivership, assignment for the
benefit  of  creditors  or  any  other  action  or   proceeding   involving  the
readjustment of the obligations and indebtedness of Borrower, or the application
of the assets of Borrower to the payment or liquidation  thereof,  or the result
of  foreclosure  or the  dissolution  or winding up of  Borrower's  assets,  all
distributions of proceeds of the collateral  shall be made to the Lender,  to GE
Capital, and to MCRC in accordance with their respective priorities of liens, as
set forth in Section 2 above.  Each party  agrees that should it receive  monies
from the collection sale, liquidation,  casualty, or other disposition of, or as
a result of its lien in,  the  collateral,  at any time  during the term of this
Agreement,  it will, unless otherwise  restricted or prohibited by law, hold the
same in trust  for and  promptly  pay over the same to the  party,  entitled  to
receive  such  monies to extent  that the same is secured by the  priorities  of
liens provided thereunder.

         4. NOTICES OF DEFAULT.  The Lender, GE Capital,  and MCRC agree to give
each  other  copies of all  notices  being  provided  to  Borrower  of  default,
acceleration,  commencement of foreclosure  proceeds or exercise of any power of
sale pursuant to the Lender Credit Documents, the GE Capital Credit Documents or
the MCRC Credit  Documents,  in each case  concurrently  with the giving of such
notice to Borrower; provided, however, that no failure of any party to give such
notice shall affect the relative  priorities  of the liens  established  in this
Agreement  or the  exercise  by any party of its rights and  remedies  under its
financing documentation.

         5.  REMEDIES.  Lender  agrees  that it shall  not seek to  enforce  its
security  interest in the GE Capital  Collateral or in any manner interfere with
GE Capital's  security  interest in the GE Capital  Collateral  unless and until
Lender  receives  written  notice from GE Capital that the GE Capital Credit has
been  satisfied  in full.  MCRC  agrees  that it shall not seek to  enforce  its
security interest in the Lender Collateral,  nor shall MCRC collect any accounts
of Borrower or in any manner interfere with Lender's security

interest in the Lender  Collateral unless and until MCRC receives written notice
from Lender that the Lender Credit has been satisfied in full.  MCRC agrees that
it shall not seek to enforce its security interest in the GE Capital Collateral,
nor shall MCRC collect any accounts of Borrower or in any manner  interfere with
GE Capital's  security  interest in the GE Capital  Collateral  unless and until
MCRC receives written notice from GE Capital that the GE Capital Credit has been
satisfied in full.

         6. TERM. This Agreement shall be irrevocable by the Lender, GE Capital,
and MCRC until all  indebtedness,  obligations,  and  liabilities of Borrower to
Lender, GE Capital, and MCRC,  respectively,  have been paid and fully satisfied
and all financing  arrangements  between Borrower,  Lenders, GE Capital and MCRC
have been terminated.

         7. ADDITIONAL  ASSURANCES.  The parties agree to execute,  acknowledge,
and  deliver  to each other all other and  further  instruments,  documents,  or
assurances  that  either  party may  reasonably  request  to give full force and
effect to the provisions of this Agreement.

the benefit of, the parties hereto, and their respective affiliates, successors,

Loan Agreements and Credit Documents with Borrower without notice to, or consent

         12. SECTION TITLES.  The section titles contained in this Agreement are
