ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH 
            RESPECT TO SECURITIES OF THE ISSUER.

            INVESTMENT AGREEMENT As of March 26, 1998, the reporting persons
            (collectively, the "Funds") entered into an Investment Agreement 
            with INCON. Roger E. Brooks, an Executive-in-Residence with 
            Ampersand Ventures, is a party to a portion of the Investment
            Agreement. Under the Agreement, as subsequently amended as of May 1,
            1998, the Funds agreed to purchase 1,638,462 Common Shares from 
            INCON at a price of $3.25 per share (an aggregate purchase price of
            $5,325,001). The Investment Agreement also contemplated that INCON
            would purchase Common Stock from existing shareholders through an
            issuer tender offer at $3.25 per share and that Mr. Brooks would
            purchase Common Stock from INCON at $3.25 per share through a
            restricted stock arrangement.

            The Funds' purchase of stock through this transaction was subject
            to certain conditions, including without limitation the condition
            that INCON shareholders (a) approve a prososed amendment to the
            Articles of Incorporation to increase the authorized common stock
            to 8,000,000 shares, and (b) approve a proposed amendment to the
            Articles of Incorporation to provide that Section 910 of the Maine
            Business Corporation Act will no longer apply to the Company.
        
            Pursuant to the Agreement, INCON has granted the Funds and Mr.
            Brooks certain registration rights covering any shares of INCON
            stock owned by them.
        
            The Agreement provides the Funds a right of first refusal on
            INCON's future sales of capital stock to parties, with certain
            exceptions.
        
            INCON also agreed to grant the Funds and Mr. Brooks a right to
            require the issuer to repurchase their shares if (i) the Company
            receives a bona fide offer from an unaffiliated third party to
            acquire INCON in a transaction that valued the Common Stock at more
            than $10 per share and (ii) the Funds endorse the offer but INCON
            declines to accept the offer.
        
                Under the Agreement, INCON has also agreed to issue additional
            shares to the Funds for nominal consideration in the event that a

            pending lawsuit between the Company and a former executive results
            in a verdict or settlement exceeding a specified amount.
        

            STOCKHOLDERS AGREEMENT In connection with the purchase of Common
            Shares on May 1, 1998 pursuant to the Investment Agreement, the 
            Funds, INCON, Mr. Brooks, Alan Lukas, Paul E. Lukas, and certain
            related parties entered into a Stockholders Agreement restricting 
            the voting and transfer of Common Shares owned by each. The shares
            beneficially owned by these stockholders represent approximately 
            72.3% of the outstanding Common Shares.

            Under the Stockholders Agreement, these shareholders have agreed to
            vote their stock (i) to limit the size of INCON's board of
            directors to five directors and (ii) to elect as those directors
            Charles D. Yie (a general  partner of A-LLP), Alan Lukas, the Chief
            Executive Officer (presently, Mr. Brooks), and one designee each of
            the Funds and Alan Lukas.
        
            These shareholders have also agreed to vote their shares in such a
            way that the Funds will be able to block certain significant
            transactions, including a merger or other sale of INCON.
        
            The shareholders who are parties to the Stockholders Agreement have
            also agreed to grant each other certain rights of first refusal to
            purchase shares that a stockholder proposes to sell to a third
            party; and to grant each other certain co-sale rights to
            participate in selling stock to a third party.
        
            FINDER'S FEE In connection with the purchase of Common Shares, the
            reporting persons paid a $183,250.02 finder's fee in cash to an
            outside, independent consultant for sourcing the issuer's investment
            proposal.

Exhibit 3
- ---------

                                         October 17, 1997


Mr. Rafiq Hasan
Corporate Finance Dimensions
26321 Marsala Way
Mission Viejo, CA 92692


Dear Rafiq:

     The purpose of this letter is to follow-up on the discussions you have had
with Paul Zigman and Roger Brooks about formalizing Ampersand's relationship
with CFD. Specifically, I would like to outline our agreement relative to your
compensation for assisting Ampersand in searching for investment opportunities
in the instrumentation and process control industry.

     OBJECTIVE: As you know, you will be working with Ampersand primarily in
support of our efforts to find investment opportunities that will leverage
Roger's extensive industry-specific skills and experience. Investment
opportunities of interest to Roger and Ampersand consist of both (1)
privately-owned companies seeking investment capital for growth or where owners
are seeking partial or total liquidity; and (2) spinoffs or divestitures of
units from major corporations - an area in which Ampersand has had considerable
investment success. The attached one-page criteria list, which Roger has
previously shared with you, offers more specific guidelines.

     While we understand that the investment process can be long and involved,
our internal goal is to establish, through your efforts, a minimum of five
ongoing dialogues with business owners during the first six months of our
relationship. Based on past experience, this should be sufficient to produce one
investment commitment by the end of one year. For these purposes, we will define
"dialogue" as an investment opportunity where (1) Ampersand has made a visit and
concluded that further work is warranted; and (2) the owner has expressed a
willingness to sell all or part of the company to Ampersand and has entered into
a good faith effort to negotiate appropriate terms.

     COMPENSATION. Ampersand is prepared to compensate you in the following
manner:

     1. You will receive a retainer of $3000 per month. This retainer will be
paid in advance at three month intervals upon receipt of an invoice from you.
With the exception of travel outside California, this retainer will cover all
expenses associated with this effort, including any advertising you wish to
place. In the extraordinary event that travel is necessary, you will submit a
request for approval in advance.

     2. Upon closing of an investment by Ampersand in an opportunity introduced
to us by CFD, you will receive a percentage of the "net consideration" paid by
Ampersand according to the following formula:

              5% of the first                $2,000,000
              4% of the next                  1,000,000
              3% of the next                  1,000,000
              1% thereafter

                                                               ----  ----

Exhibit 3 - Continued
- ---------------------


Mr. Rafiq Hasan

     For purposes of this agreement "net consideration" means (a) the amount of
cash paid by Ampersand, plus (b) the fair market value of any securities or
other property conveyed by Ampersand as additional consideration, plus (c) the
discounted present value of any liabilities assumed by Ampersand, less (d) the
amount of any cash or cash-equivalent assets acquired by Ampersand, either
directly or as part of the assets of the target company.

     This fee will be paid with respect to (a) any net consideration paid at
closing, (b) any future installment payments, if and when such payments are
made, except that Ampersand may, at its election, pay you based on the
discounted present value of such payments at closing, and (c) any contingent
payments, such as earn-outs and payments out of escrow, only if and when such
payments are made.

     3. Both Ampersand and you agree that we will make a best faith effort to
convert the cash fee described above into equity in the target company. Given
that any such conversion is heavily dependent on the specific circumstances of
the investment, the precise terms of your equity participation will be
negotiated on a case-by-case basis. We do agree that any such conversion will be
made at terms that offer a premium to the cash fee equivalent.

     4. The term of this Agreement shall be one year. Either party, however, may
cancel this arrangement at the end of six months (i.e. by April 15, 1998).

     NEXT STEPS. Assuming you are in agreement with these terms, please sign
this document and return it to Paul's attention. I will then ask Paul and Roger
to continue leading the effort on Ampersand's front, and specifically to draft
with you a work plan detailing more concretely how CFD and Ampersand will work
together over the coming months.

     On behalf of my colleagues, let me say in closing that we are looking
forward to partnering with you on this effort and, in the process, to
establishing a long term working relationship between our two firms.



                                                Sincerely yours,


                                                /s/ Donald B. Hawthorne
