Dr. Juan J. Amodei
TRIPLE I CORPORATION
One Lowell Research Center

Lowell, MA 01852

Dear Juan:

     As you are aware, Polaroid Corporation has made an equity investment of
$800,000 and owns in excess of 20% of Triple I Corporation's outstanding common
stock. Polaroid made that investment in anticipation of significant appreciation
and continues to encourage Triple I's success in its various endeavors, and in
particular those endeavors which maximize use of Polaroid's film products.

     Due to the fact that Triple I failed to meet certain milestones specified
in the License And Collaboration agreement between Polaroid and Triple I dated
November 28, 1994, as amended by fax from you dated April 26, 1996, a copy of
which is enclosed (the "Agreement"), Polaroid, by letter of May 23, 1996, gave
notice to Triple I of the conversion of its exclusive right to market and sell
Medium in the PCB Field to a non-exclusive right in accordance with Section 4d
of the Agreement.

     You have requested that Polaroid reconsider and withdraw its notice of
conversion of exclusive Medium marketing rights to non-exclusive rights and make
certain other amendments to the Agreement. Polaroid agrees with the essence of
your proposal and offers by this letter to make the modifications that you
requested. To avoid confusion concerning expectations, I have set forth below
the amendments to the Agreement that we discussed and ask for your prompt review
and consideration.

     The Agreement is hereby amended as follows:

1.   Add as the last sentence to paragraph 4d:

          "In no event will the quality of Medium provided by Polaroid to Triple
          I be considered the failure of Polaroid to meet a material obligation
          required by this 


<PAGE>   16

          Agreement if Medium of like quality is commercially sold by Polaroid
          for use in commercially available plotters used in the graphics field.

2.   Delete Performance Milestone 3 and substitute the following:

          3.   Year One under this agreement shall mean the twelve month period
               ending May 31, 1996.

3.   Delete Performance Milestone 4 and substitute the following:

          4.   * sales shall meet or exceed the following for each year
               specified under the Agreement as follows: *. Quarterly milestones
               for * sales shall be determined by dividing any year's sales
               performance number into four approximately equal portions.

4.   Delete Performance Milestone 5 and substitute the following:

          5.   * sales shall meet or exceed the following * for each year
               specified under the Agreement as follows: *. Quarterly milestones
               for * sales shall be determined by apportioning any year's sales
               performance number into four approximately equal portions.

5.   Delete Performance Milestone 7 and substitute the following:

          7.   Triple I agrees to launch the * no later than the * . Triple I
               further agrees that it will launch the * in either * no later
               than the * under the Agreement

6.   In Performance Milestone 8, line 1, delete "fiscal".

     In addition, before August 1, 1996, Triple I will either pay to Polaroid
$90,000, in which event Polaroid will transfer title to its plotter now resident
at Triple I's facility to Triple I, or Triple I will return the plotter to
Polaroid at Polaroid's expense. Also, as of the date of execution of this
amendatory letter by Triple I, Triple I represents that there is no outstanding
failure of Polaroid to meet any material obligation required by the Agreement.

     Juan, I believe we continue to have the basis for a mutually beneficial
relationship. As a consequence of your acceptance of these amendments to the
Agreement, the letter of May 23, 1996 from Polaroid to Triple I, which converted
Triple I's Medium marketing rights from exclusive to non-exclusive, will be
automatically withdrawn and of no legal effect. Polaroid's offer to amend the
Agreement and withdraw the May 23, 1996 letter will expire at 5:00 p.m. on June
26, 1996 if not accepted by Triple I before that time. Acceptance may be
communicated by signing one copy of this letter where indicated below and
returning it to me.

                                         Sincerely yours,

                                         /s/ Robert M. Delahunt

Re:  License And Collaboration Agreement
     -----------------------------------

Dear Bob:

     On November 23, 1994, Triple I Corporation ("Triple I") and Polaroid
Corporation ("Polaroid") entered into a License and Collaboration Agreement,
which was amended on June 17, 1996 (the agreement and all amendments are hereby
referred to as the "Agreement"). This letter is intended to state the parties'
understanding as to certain performance milestones, listed in Sections 4 and 5
of EXHIBIT A under the Agreement ("Performance Milestones"), that Triple I must
achieve as part of the Agreement.

     Polaroid and Triple I acknowledge their differences in respect of any right
of Polaroid to convert Triple I's exclusive rights to market MEDIUM in the PCB
field from exclusive to non-exclusive rights. Nonetheless, Polaroid and Triple I
hereby agree that Polaroid will not act in respect to the Year-2 quarterly
Performance Milestones until May 31, 1997, at which time Triple I is required to
meet the annual Performance Milestones due on that date. If Triple I fails to
meet these annual requirements, Polaroid, at its discretion, may proceed in
accordance with Section 4(d) of the Agreement.

     Polaroid and Triple I also agree that Industrial Imaging Corporation
("Industrial Imaging"), the parent corporation of Triple I, shall include
certain disclosures, in the form attached as EXHIBIT A, in Industrial Imaging's
Form 8-K to be timely filed in accordance with the rules of the Securities and
Exchange Commission following the completion of the exchange of shares between
Triple I and Industrial Imaging. Simultaneously with the agreement by the
parties to the above terms of this letter, Polaroid, a shareholder of Triple I,
agrees to execute its Shareholder Exchange Agreement, which will enable Triple I
to proceed with the transaction involving Industrial Imaging.

     Triple I also acknowledges that, as of the date of this letter, there is no
outstanding failure of Polaroid to meet any material obligation required by the
Agreement. In no event will the 


<PAGE>   19

quality of the MEDIUM provided by Polaroid to Triple I be considered the failure
of Polaroid to meet a material obligation required by this Agreement if MEDIUM
of like quality is commercially sold by Polaroid for use in commercially
available plotters used in the graphics field.

     Triple I agrees that it will not, in the event it fails to meet the full
Year-2 Performance Milestones by the end of May 1997, invoke in justification
thereof any alleged failure of or responsibility in Polaroid, as of the date of
this letter.

     For the purpose of testing the full Year-2 Performance Milestones set for
performance by May 31, 1997, * sales, shall only be considered sales upon the
receipt of Triple I of *.

     All of the provisions of the Agreement, as amended June 17,1996, remain in
full force and effect to the extent not inconsistent with the provisions of this
letter.

     Triple I acknowledges that the Agreement does not prohibit Polaroid from
accepting inquiries from any person, partnership, corporation or other third
party in respect of possible mutual business opportunities involving any plotter
and MEDIUM for use in the PCB field (including opportunities based upon sales of
MEDIUM by any such third party); and the Agreement shall not be construed in any
manner to preclude or inhibit any such discussions. Polaroid agrees, however,
that it will not, except with Triple I's prior written approval, enter into any
agreement with any such third party authorizing the marketing of MEDIUM by such
party in the PCB field unless Triple I shall have failed to meet its full Year-2
Performance Milestones and Polaroid shall have served notice upon Triple I of
the conversion of its exclusive marketing rights to non-exclusive rights.

     If you agree with the above terms, kindly acknowledge your agreement by
signing this letter below where indicated and returning it to me, along with a
copy of the Shareholder Agreement signature page containing Polaroid's
signature.
