Dr. Juan J. Amodei
TRIPLE I CORPORATION
One Lowell Research Center
847 Rogers Street
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:

<PAGE>   16




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 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. PLOTTER unit sales shall meet or exceed the following for 
                     each year specified under the Agreement as follows: *. 
                     Quarterly milestones for PLOTTER unit 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. Polaroid MEDIUM sales shall meet or exceed the following * 
                     for each year specified under the Agreement as follows: *. 
                     Quarterly milestones for MEDIUM 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 MEDIUM and PLOTTER no later 
                     than the * . Triple I further agrees that it will launch 
                     the MEDIUM and PLOTTER 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.

         *Confidential treatment requested as to certain portions, which
portions are omitted and filed separately with the Commission.

         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

                                                       January 10, 1997

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.

<PAGE>   19

         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 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, PLOTTER unit 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.
