INFORMATION TO BE INCLUDED IN THE REPORT

Item 2.   Acquisition or Disposition of Assets

     On June 7, 1996, the registrant entered into an asset purchase agreement
(the "Agreement") with Alternate Circuit Technology, Inc. ("ACT") and the
shareholders of Alternate Circuit Technology, Inc. (the "ACT Shareholders").
Pursuant to the Agreement, the registrant shall purchase all of ACT's assets,
properties (tangible and intangible) and rights used in or related to the
business conducted by ACT (the "Assets") except certain excluded assets, such
excluded assets having a total value of $1,481,550.08.

     ACT is in the business of owning, operating and managing a quick turnaround
printed circuit board manufacturing facility in Massachusetts.  The Assets
include ACT's cash, accounts receivable, inventory, equipment and leasehold
improvements, tools and supplies, all general intangibles used in the business,
ISO certificates, goodwill, contract rights, intellectual properties, and rights
under the MIFA lease financing.  The registrant intends to continue to use the
Assets as ACT did, in the operation and management of a printed circuit board
manufacturing facility in Massachusetts.

     The purchase price for the Assets consists of assumed liabilities having an
approximate value of $4,495,475.00, cash of $8,772,182.00 subject to adjustment,
and 50,000 shares of the registrant's $0.001 par value common stock.  The cash
portion of the purchase price will be increased or decreased, as the case may
be, by the difference between ACT's net worth determined according to the
registrant's certified public accountants, on the close of business on the day
immediately preceding the closing date and $3,911,420.00.  In no event will the
adjustment increase the total purchase price to more than $14,750,000.00 plus
the amount of cash included in the Assets to be transferred.  The principles
followed in determining the amount of such consideration included an evaluation
of ACT's  book value and revenues.  The consideration for the Assets is
approximately two times the book value.  The source of the funds used to acquire
the Assets is the registrant's working capital.

          The parties acknowledge and agree that the Purchaser may designate a
wholly-owned subsidiary of Purchaser to acquire the Assets and to make the
payments; provided, however, that the Purchaser's obligations hereunder, to make
payments to Seller or otherwise, shall not be discharged by such designation by
the Purchaser.  If Purchaser does designate such a subsidiary, then except as
provided in the previous sentence, all references to Purchaser in this agreement
shall also be deemed to refer to such subsidiary.

     2.   Purchase Price.
          --------------

          2.1.  Purchase Price.
                --------------

          The purchase price for the Assets ("the Purchase Price") shall, in
addition to the assumption of the Assumed Liabilities, consist of:

                (i)   cash of Eight Million Seven Hundred Seventy-two Thousand
One Hundred Eighty-two and 14/100 Dollars ($8,772,182.14) subject to adjustment
as provided in Section 2.2; and

                (ii)  shares ("Acquired Shares") of Zycon Corporation $0.001 par
value common stock, in such amount determined as follows:

          The number of Acquired Shares to be issued at the Closing shall be
determined by dividing (a) $600,000.00 by (b) the Market Price (as defined
below) with respect to the Zycon Common Stock on the date of the Closing. For
purposes of the foregoing "Market Price" with respect to the Zycon Common Stock
shall be the average of the high and low trading prices for the last three days
of trading preceding the Closing of the Zycon Common Stock reported on the
National Market System of National Association of Securities Dealers Automated
Quotations System ("NASDAQ") on such date. If the Market Price, as calculated
above, is less than $12.00 per share, then for purposes of this Section the
Market Price shall be deemed to equal $12.00 per share. Similarly, if such
Market Price as calculated above is greater than $15.00 per share, then for
purposes of this Section the Market Price shall be deemed to equal $15.00 per
share. Purchaser shall insure that no director, 10% or greater shareholder or
Executive Officer (as identified in Purchaser's Proxy Statement of March 28,
1996) purchases, sells or exercises options for its shares of Zycon Common Stock
during the five days of trading immediately preceding the Closing.

          The Acquired Shares shall be subject to the Registration Rights
Agreement attached as Exhibit 2.1.

          2.2.  Adjustment of Purchase Price.
                ----------------------------

          The cash portion of the Purchase Price will be increased or decreased,
as the case may be, by the difference between the Seller's net worth determined
according to the Seller's Financial Statements as audited by the Purchaser's
Certified Public Accountants, on the close of business on the day immediately
preceding the Closing Date and $3,911,420.80, provided, however, that the first
$220,000.00 of net income earned by Seller between March 31, 1996 and the
Closing Date shall not cause an increase in

                                       4
<PAGE>
 
the Purchase Price. For purposes of this Section, Seller's Financial Statements
are to be presented in accordance with generally accepted accounting principles
consistently applied. Furthermore, if prior to the Closing Date Purchaser orders
products or services from Seller, the profit or loss on such orders shall not be
taken into account for purposes of such adjustment. The profit or loss shall be
determined by Seller in the manner consistent with Seller's past practices
and/or Seller's generally applicable cost accounting methods and procedures.

          The Seller's net worth shall be determined only with reference to
Assets and Liabilities reflected on Schedule 2.2. In no event shall the
adjustment increase the total Purchase Price to more than $14,750,000 plus the
amount of cash included in the Assets to be transferred.

          2.3.  Allocation.
                -----------

          The Purchase Price for the Assets and the Assumed Liabilities shall be
allocated as set forth in Schedule 2.3 hereto. Such Schedule 2.3 shall be
finalized in a form mutually acceptable to the parties and their accountants,
not later than 15 days after Closing.   The parties hereto agree that the
allocation of the Purchase Price is intended to comply with the allocation
method required by Section 1060 of the Internal Revenue Code of 1986, as amended
(the "Code").  The parties shall cooperate to comply with all substantive and
procedural requirements of Section 1060 of the Code and any regulations
thereunder, and the allocation shall be adjusted if, and to the extent,
necessary to comply with the requirements of Section 1060 of the Code.  Neither
the Purchaser, the Seller nor any Shareholder will take, nor permit any
affiliate to take, for federal, state or local income tax purposes, any position
inconsistent with the allocation set forth in Schedule 2.3 hereto, or, if
applicable, such adjusted allocation. Purchaser and Seller agree to attach to
its tax returns for the tax year in which the Closing shall occur an information
statement on Form 8594, which shall be completed in accordance with the
allocations set forth in Schedule 2.3.

     3.   Representations and Warranties of the Seller and the Shareholders.
          ------------------------------------------------------------------

          The Seller and the Shareholders hereby jointly and severally represent
and warrant to the Purchaser as follows:

          3.1.  Organization and Good Standing

conducted, holds all material franchises, licenses and permits necessary and
required therefor, and is duly qualified or licensed to do business and is in

it or the ownership, lease or operation of its properties requires a license or
qualification, which jurisdictions are listed on Schedule 3.1 hereto.

          3.2.  Authority and Compliance.
                ------------------------

          The execution and delivery of this Agreement, and the consummation of
the transactions contemplated hereby have been duly and validly authorized by
the Seller's Board of Directors.  The Seller and each Shareholder has all
requisite power to execute and deliver this Agreement and to perform the
transactions contemplated hereby.  No other corporate proceedings on the part of
Seller or any Shareholder are necessary to authorize this Agreement or to
consummate the transactions contemplated hereby.  Except as listed on Schedule
3.2, the execution and delivery by Seller and each Shareholder of this Agreement
and the transactions contemplated hereby is not prohibited by, does not violate
any provision of or result in any material breach of (or give rise to any right
of termination, cancellation or acceleration under) (i) any judgment, order or
decree applicable to Seller or any Shareholder, (ii) the Articles of
Incorporation or Bylaws of the Seller, or (iii) any material promissory note,
indenture or any evidence of indebtedness or security therefor, lease, contract,
purchase or other commitment or any other agreement to which Seller is a party
or by which it is bound, and has not resulted and will not result in the
creation or imposition of any lien, security interest or encumbrance in favor of
any third party on any of Seller's assets.

          This Agreement has been duly executed and delivered by Seller and each
Shareholder and, assuming due execution and delivery by the Purchaser, is a
valid and legally binding obligation of Seller and each Shareholder enforceable
in accordance with its terms, except as enforcement may be limited by
bankruptcy, insolvency or other similar laws affecting the enforcement of
creditors' rights generally. Such execution, delivery and performance does not
require any consent, waiver, approval, authorization or permit of, or filing
with or notification to, any governmental or regulatory authority, except for
filings as may be required under the Securities Act of 1933, as amended (the
"Securities Act"), the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), state securities or blue sky laws.

          The Shareholders hold, in the aggregate, all of the outstanding
capital stock of the Seller.

          3.3.  Status of Liabilities.

payable to any persons.

          3.4.  Assets.
                ------

          The Seller has good, valid and marketable title to all of the Assets,
free and clear of all Encumbrances of any nature whatsoever, except (i) as set
forth on Schedule 3.4 hereto (the "Permitted Encumbrances"), or (ii) liens for
current taxes not yet due and payable. At the Closing the Seller will have good,
valid and marketable title to all of the Assets, free and clear of all
Encumbrances of any nature whatsoever other than the Assumed Liabilities and the
Permitted Encumbrances. All of the Assets are usable in the ordinary course of
the Business consistent with past practice. The Assets include all rights
necessary to the conduct of Business by the Purchaser in the manner it is
presently conducted by the Seller and no property of the Seller that is not
included in the Assets constitutes property or rights material to the Business.

          3.5.  Taxes and Tax Returns.
                ---------------------

          The Seller has filed or caused to be filed on a timely basis all
federal, state, local, foreign and other tax returns, reports and declarations
(collectively, "Tax Returns") required to be filed by the Seller in connection
with the Business. All Tax Returns filed by or on behalf of the Seller in
connection with the Business are materially complete in all respects. To the
Seller's knowledge, the Seller has paid all income, estimated, excise,

periods covered by such Tax Returns (whether or not reflected thereon). To the
Seller's knowledge, there are no tax liens on any of the properties or assets,
real, personal or mixed, tangible or intangible, of the Seller. Since March 31,
1996, the Seller has not incurred any Tax liability in connection with the
Business other than in the ordinary course of business. No deficiency in Taxes
for any period has been asserted in writing by any taxing authority which
remains unpaid at the date hereof (the results of any settlement being set forth
in Schedule 3.5), no written inquiries or notices have been received by the
Seller from any taxing authority with respect to possible claims for Taxes,
neither the Seller nor the Shareholders have any reason to believe or have
knowledge that such an inquiry or notice is pending or threatened, and to
Seller's knowledge there is no basis for additional claims or assessments for
Taxes. The Seller has not agreed to the

                                       7
<PAGE>
 
extension of the statute of limitations with respect to any Tax Return or tax

employees of the Business with salaries exceeding $50,000; or (vi) any material
liability incurred with respect to the Business, other than liabilities incurred
in the ordinary course of business consistent with past practice, or any lien or
encumbrance discharged or satisfied with respect to the Business or the Assets,
or any failure to pay or discharge when due any liability of which the failure
to pay or discharge has caused or will cause any material damage or risk of
material loss to the Business or any of the Assets.

          Except as set forth on Schedule 3.6 hereto, there has been no
amendment, waiver or termination of any material agreement, contract,
commitment, lease, plan, permit, authorization or arrangement ("Contract or
License") which has been delivered to Purchaser in connection with its due
diligence review, or any other Contract or License, which materially relates to
the Seller or the Business, or any waiver of any rights of substantial value

          3.7.  Legal Proceedings; Compliance with Law.
                ---------------------------------------

                (a) Except as set forth on Schedule 3.7(a), to Seller's
knowledge there is no lawsuit, action, arbitration, administrative or other
proceeding, criminal prosecution or governmental investigation or inquiry
("Litigation") that is

                                       8
<PAGE>
 
pending or, to the Seller's and the Shareholders' knowledge, threatened against
or related to or otherwise affecting the Seller, the Business, the Assets or any
property leased or rented to the Seller. There has been no material Default
(defined below) under any Regulations (defined below) applicable to the Seller
with respect to the Business or the Assets, including Regulations relating to
pollution or protection of the environment. As used in this Agreement, "Default"
means (a) a breach, default or violation, or (b) the occurrence of an event that
with the passage of time or the giving of notice, or both, would constitute a
breach, default or violation. As used in this Agreement, "Regulation" means any
statute, law, ordinance, regulation, order or rule of any federal, state, local,
foreign or other governmental agency or body or of any other type of regulatory
body, including, without limitation, those covering environmental, energy,
safety, health, transportation, bribery, record keeping, zoning,
antidiscrimination, antitrust, wage and hour, and price and wage control
matters.

                (b) Without limiting the generality of Section 3.7(a), there has
not been at any time since the Seller's inception, or otherwise to the knowledge
of the Seller or the Shareholders (i) any Environmental Condition (defined
below) at or relating to the premises at which the Business has been conducted,
or at or relating to any property owned, leased or operated by the Seller (or
any predecessor thereof) with respect to the Business at any time, or at or
relating to any property at which wastes generated by the Seller or the Business
have been deposited or disposed of, nor has the Seller received written notice
of any such Environmental Condition, or (ii) any written notice received by the
Seller that the Seller violated any Regulation or Environmental Law governing
the shipment or storage of hazardous materials. "Environmental Condition" means
any condition or circumstance, whether created by the Seller or any third party,
that (i) requires abatement or correction under an Environmental Law (defined
below), (ii) is reasonably likely to give rise to any civil or criminal
liability under an Environmental Law, or (iii) is reasonably likely to create a
public or private nuisance, including, but not limited to, the presence of
asbestos, PCBs, hazardous substances, radioactive waste or radon. "Environmental
Law" includes all Statutes and Regulations relating to pollution or protection
of the environment as well as any principles of common law under which a party
may be held liable for the release or discharge of any materials into the
environment including, but not limited to, nuisance and trespass.

                (c) The Seller has obtained all governmental permits, licenses,
registrations, certificates of occupancy, approvals and other authorizations
(the "Governmental Permits"), all of which are listed in Schedule 3.7(c) along
with their respective expiration dates, that are required for the complete

                                       9
<PAGE>
 
operation of the Business as presently operated and that if not obtained could
have a material adverse effect on the Business. To Seller's knowledge, all of
the material Governmental Permits are presently valid and in full force, and, to
the Seller's knowledge, no revocation, modification, cancellation or withdrawal
thereof has been threatened. The Seller has filed such timely and complete
renewal applications as may be required with respect to its Governmental Permits
that if not obtained would have a material adverse effect on the Business. The
Seller is in full compliance with its Governmental Permits. The assignment of
such Governmental Permits to Purchaser hereunder will not require any filing,
consent or approval, except as specified on Schedule 3.7(c).

          3.8.  Intellectual Property.
                ----------------------

                (a) The Seller owns or has the legal right to use without
limitation and payment of royalties, the patents, patent applications,
inventions, copyrights, trademarks, trade names, licenses, software (whether
existing and under development) and other legally protectable rights used in its
business and described in Schedule 3.8 ("the Intellectual Properties"), each of
which is included in the Assets. Except to the extent set forth in Schedule 3.8,
all the Intellectual Properties are valid and in good standing, freely
assignable, and are subject to no material liens, charges, contractual rights
or, to the Seller's and the Shareholders' knowledge, claims or other interests
of any other person and are adequate and sufficient to permit the Company to
conduct the Business. Except as set forth on Schedule 3.8, no rights under any
patents, inventions, copyrights, trademarks, trade names, licenses or other
legally protectable rights owned solely or partially by others, including
directors, officers or employees of the Seller, are required by the Seller in
connection with the conduct of the Business, and the consummation of the
transactions contemplated by this Agreement will not materially alter or impair
any such rights.

                (b) The Seller and the Shareholders have no knowledge of, and
have received no notice to the effect that any product the Seller manufactures
or sells or distributes or any services the Seller provides, or the marketing or
use by the Seller or another of any such product or service, may infringe any
patent, trademark, trade name, copyright or legally protectable right of
another. All trade secrets, if any, owned or used by the Seller are, to the
Seller's and the Shareholders' knowledge, owned free of any adverse claims,
rights or encumbrances as to its exclusive rights thereto, and the Seller has
used reasonable efforts to protect its rights to continued secrecy thereof.

          3.9.  Distributors, Customers or Suppliers.
                ------------------------------------

          Except as set forth in Schedule 3.9, the Seller is not aware that any
customer, distributor or supplier intends to cease doing business with the
Seller or to alter materially the amount of business done with Seller due to
consummation of the transactions contemplated by this Agreement or any other
reason.  Schedule 3.9 lists all customers, distributors and suppliers of the
Seller during the prior twelve months.

          3.10.  Acquired Shares.
                 ---------------

          In acquiring the Acquired Shares, the Seller acknowledges, and to the
extent provided in Schedule 3.10, represents and warrants to the Purchaser those
matters set forth on Schedule 3.10.

          3.11.  Financial Statements; No Undisclosed Liabilities
                 ------------------------------------------------

          The Seller delivered to the Purchaser balance sheets of the Business
as of November 26, 1993, November 25, 1994, November 24, 1995, and March 31,
1996, and the related statements of operations, cash flows and retained
earnings, together with the notes thereto, if any, for the periods then ended,
which financial statements, except for the statement of March 31, 1996, have
been audited by the certified public accountants of the Seller (all of the
foregoing, the "Financial Statements"). The Financial Statements are true and
correct in all material respects and have been prepared in accordance with
generally accepted accounting principles applied consistently throughout the
periods involved. The Financial Statements fairly present the financial position
of the Business as of the dates thereof and the results of the operations of the
Business and its cash flows for the periods indicated. The balance sheets
contained in the Financial Statements fairly reflect all liabilities of the
Business of the types normally reflected in balance sheets prepared in
accordance with generally accepted accounting principles except for ordinary
adjustments customarily made to interim financial statements in accordance with
generally accepted accounting principles. Except as set forth on Schedule 3.11,
the Seller has no liabilities or obligations (absolute, accrued, fixed,
contingent liquidated, liquidated or otherwise) except liabilities arising in
the ordinary course of the Business consistent with past practice which are not
required under generally accepted accounting principles to be disclosed or
reserved in its Financial Statements, as defined in Section 3.11.

          True and correct copies of the Financial Statements are attached
hereto as Schedule 3.11.

                 (iii)  The Seller has not received any written notice of any
violation of any laws, rules, regulations or ordinances (including, without

to the Leased Parcels or requesting or requiring the performance of any repairs,
alterations or other work in order so to comply.

                 (iv)   The Seller has not received written notice of any
assessment for public improvements or otherwise which is due and remains unpaid

conditioning systems, elevator systems and all other mechanical systems and
equipment at the buildings and other improvements constituting a part of the RRT
Property and such similar systems which it is required to maintain in regards to
the 3rd Party Property are in good working order, subject to normal wear and
tear and the age and condition of the RRT Property and the 3rd Party Property,
respectively.

                 (vi)   To the Seller's and Shareholders' knowledge, the Leased

                 (vii)  The 3rd Party Lease is in full force and effect and
Seller has received no written notice of any material default and Seller knows
of no event or condition currently existing which would constitute a material
default or breach of the 3rd Party Lease.

          3.13.  Licenses.
                 --------

                 (i)    Except as listed on Schedule 3.13, the Business does not

license granted by another entity and has not licensed its right in any current
or planned products, designs or services to any other entities involving
consideration and/or liability of $1,000.00 or more.

                 (ii)   The Seller has the right to use all computer software,
including all property rights constituting part of the computer software, used

Software"). A list of all written licenses pertaining to the Computer Software
with a replacement cost of $2,500.00 or more is set forth in Schedule 3.13(ii)
attached hereto (the "Licenses"). To the Seller's knowledge, the Licenses are
valid or enforceable by the Seller and are transferable to Purchaser without
further action except as set forth in Schedule 3.13(ii). Except as listed in
Schedule 3.13(ii), the Seller has not granted any licenses to use the Computer
Software or any sub-licenses with respect to any of the Licenses, involving
consideration and/or liability of $2,500.00 or more.

           3.14.  Accounts Receivable; Inventories and Equipment.
                  ----------------------------------------------

           The accounts receivable of the Business that are being acquired by

business. The inventories and equipment of the Business are in all material
respects merchantable and fully usable in the ordinary course of business.

bound (including, in the case of loan agreements, a description of the amounts
of any outstanding borrowings thereunder and the collateral, if any, for such
borrowings); (ii) obligations and liabilities of the Seller pursuant to
uncompleted orders for the

                                      13
<PAGE>
 
purchase of materials, supplies, equipment and services for the requirements of
the Business with respect to which the remaining obligation of the Seller is in
excess of $10,000.00; and (iii) material contingent obligations and liabilities
of the Seller related to the Business; all of the foregoing being hereinafter
referred to as the "Contracts". To Seller's knowledge neither the Seller nor any
other party is in material default in the performance of any covenant or
condition under any Contract and no written claim of such a default has been
received by Seller and no event has occurred which with the giving of notice or
the lapse of time would constitute a material default under any covenant or
condition under any Contract. Except as disclosed on Schedule 3.15, the Seller
is not a party to any Contract which would terminate or be adversely affected by
the consummation of the transactions contemplated by this Agreement. The Seller
has provided Purchaser true, correct and complete copies of all written
Contracts requested by Purchaser and descriptions of all oral Contracts. None of

     8.   Covenant Not to Compete.
          ------------------------

          As a material inducement to the Purchaser to enter into this
Agreement, and acknowledging that the Seller and each of the covenanting
Shareholders have established expertise and experience in the Business, the
Seller and Robert Romano and Wayne Ewald (with Messrs. Romano and Ewald
collectively the "Covenanting Shareholders") agree they shall not, at any time
within the three-year period immediately following the date of Closing under
this Agreement (the "Restricted Period"), directly or indirectly, engage in, or
have any interest on behalf of itself or others in any person, firm, corporation
or business (whether as an employee, officer, director, agent, security holder,
creditor, partner, joint venturer, beneficiary under a trust, investor,
consultant or otherwise) that engages within the Restricted Territory (defined
below) in the Business, provided, however, the Covenanting Shareholders shall
not be restricted by this Section from owning securities listed on a National
Securities Exchange or regularly traded by national securities dealers, so long
as such investment does not exceed 1.0% of the market value of the outstanding
securities of such corporation. The "Restricted Territory" means worldwide. If
the provisions of this Section 8 should ever be deemed to exceed the time or
geographic limitations or any other limitations permitted by applicable laws,
then such provisions

<PAGE>
 
shall be deemed reformed to the extent required permitted by applicable laws.

that the remedy at law for any breach of the foregoing covenant will be
inadequate and that the Purchaser or any affiliate thereof, in addition to any
other relief available to it, shall be entitled to temporary and permanent
injunctive relief without the necessity of proving actual damages. In addition,
in any action to enforce the foregoing covenant by the Seller or a Covenanting
Shareholder, the Purchaser shall be entitled to recover from the Seller or such
Shareholder against whom enforcement is sought all costs and expenses incurred
by the Purchaser in connection with such action, including without limitation
reasonable attorneys' fees and expenses incurred by the Purchaser. The Seller
and each Covenanting Shareholder acknowledges and understands that the Purchaser
is relying upon the covenant made by the Seller in this Section 8 in proceeding
with the Closing.

          At the end of the Restricted Period, Purchaser agrees to pay each
Covenanting Shareholder who fully complies with his obligations hereunder, the
sum of $100,000.

     9.   Closing
          -------

          9.1.  Time and Place of Closing.
                --------------------------

          The closing of the purchase and sale of the Assets as set forth herein
(the "Closing") shall be held at the offices of Maselan & Jones, P.C., 50 Milk
Street, Boston, Massachusetts 02109, on June 18, 1996 at 9:00 A.M., local time,
or the earlier of (i) such time mutually agreed upon by Seller and Purchaser or
(ii) sixty (60) days from the execution hereof, provided, however, that the
transactions entered into at the Closing shall be deemed to have occurred
simultaneously, and shall become effective as if they had occurred at 12:01 A.M
on the day after the Closing.

          9.2.  Tax Matters.
                ------------

          All transfer, documentary, sales, use, stamp, registration, value
added and other such Taxes and fees (including any penalties and interest),
incurred in connection with this Agreement shall be borne and paid by the Seller
when due, and the Seller will, at his own expense, file all necessary Tax
Returns and other documentation with respect to all such Taxes and fees, and, if
required by applicable law, the Purchaser will join in the election of any such
Tax Returns and other documentation.

          9.3.  Documents and Items to be Produced at Closing by Purchaser.
                -----------------------------------------------------------

          At the Closing, Purchaser shall (except as provided in subparagraph
(c)) deliver to Seller:

                                      33
<PAGE>
 
          (a) Federal funds wire transfer, certified check or other immediately
available U.S. funds payable to the Seller in the amount of $7,772,182.14.
Seller acknowledges that Purchaser has deposited with State Street Bank (the
"Escrow Holder") $250,000 to be applied against the Purchase Price, which shall
be released to Seller at Closing. If Purchaser defaults under its obligations
under this Agreement and refuses to close the transaction as provided in Section
9.1, Seller will suffer damages and incur costs as a result of such default.
Because it will be difficult to determine the exact amount of such damage, the
parties agree that the deposit in the amount of $250,000 shall be paid to Seller
as liquidated damages which the parties agree is a reasonable estimate of
Seller's costs and damages. Such damages shall be Seller's sole remedy at law,
equity or otherwise with respect to any breach of this Agreement by Purchaser
which results in a failure to close this Agreement as contemplated in Section 9.
If Seller breaches this Agreement or if Purchaser declines to close because of
the failure of any condition set forth in Section 6, such deposit shall
immediately be returned to Purchaser.

          (b) Three share certificates in equal amounts representing the
Acquired Shares or irrevocable instructions to Purchaser's Transfer Agent to
issue and deliver such certificates to Seller. No fractional shares need be
delivered or issued. The value of any fractional shares will be paid to Seller
at Closing by check.

          (c) Purchaser shall deposit with the Escrow Holder by Federal Funds
wire transfer, certified check or other immediately available U.S. Funds the
amount of $750,000, less the adjustment called for under Section 2.2, as
tentatively determined by the parties by Closing, with such amount to be held in
an interest bearing account.

          If the final determination under Section 2.2 increases the cash
portion of the Purchase Price to more than $8,772,182.14 (increased or decreased
by the tentative adjustments made as of the Closing), then the Purchaser shall,
within 5 business days of such final determination, deposit with the Escrow
Holder the additional amount due. If, and to the extent, the cash portion of the
Purchase Price as finally determined is less than $8,772,182.14 (plus or minus
the tentative adjustments determined as of closing), then within 5 business
days after having received notice of such final determination from the
Purchaser, Escrow Holder shall return such difference to Purchaser. The final
determination of the adjustment to the cash portion of the Purchase Price shall
be determined promptly (but in no event later than 45 days after ACT closes its
books) after the Closing by Purchaser's certified public accountants, whose
decision shall be final and binding on the parties; provided, however, that if
Seller disputes such determination, the parties hereto agree to binding
arbitration pursuant to the rules of the American Arbitration Association to
determine the final adjustment pursuant to Section 2.2, with such arbitration to
be held in Boston, Massachusetts. The Escrow Holder

                                      34
<PAGE>
 
shall, within five (5) business days of receiving notice of the final
adjustment, pay to Seller any additional amount necessary to reduce the escrow
to $450,000.

          On January 31, 1997, or 195 days after Closing, whichever is later,
Escrow Holder, shall pay to Seller the balance in the escrow account including
any interest earned during the escrow, but less the costs and fees of the Escrow
Holder. Notwithstanding the preceding sentence, if at any time before the
disbursement of such funds the Purchaser advises the Escrow Holder and Seller in
writing that a claim has been made against the Purchaser for any liability,
obligation or alleged liability or obligation of the Seller which is not an
Assumed Liability, of the name of the creditor and the amount claimed by the
creditor, then Escrow Holder shall hold 150% of the amount claimed in escrow
until Escrow Holder has received Purchaser's written acknowledgment that such
claim has been fully satisfied or finally disposed of by Seller. Notwithstanding
the foregoing, (i) Escrow Holder shall not retain any amounts for claims not
indemnified hereunder by Seller or the Shareholders, and (ii) the defense of any
claims shall be governed pursuant to Section 10 hereunder.

               (d) Registration Rights Agreement in the form of Schedule 2.1,
duly executed by Purchaser.

               (e) Employment Agreements with Robert R. Romano and Wayne R.
Ewald, in the form of Exhibit 9.3.(e), duly executed by Purchaser.

               (f) Escrow Agreement in the form of Exhibit 9.3(f) executed by
Purchaser.

               (g) Opinion of counsel as provided in Section 7.5.

               (h) Corporate Authorization as provided in paragraph 7.3.

          9.4. Documents and Items to be Provided at Closing by Seller and
               -----------------------------------------------------------
               Shareholders.
               -------------

          At the Closing, Seller (and Shareholders, as applicable) shall deliver
to Purchaser:

               (a) Such bills of sale with covenants of warranty, assignments
and other instruments and documents of conveyance and transfer, in a form
reasonably satisfactory to the Purchaser and its counsel, as shall be necessary
and effective to transfer and assign to, and vest in, the Purchaser all of the
Seller's right, title and interest in and to the Assets, and, simultaneously
with such delivery, all such steps will be taken as may be required to put the
Purchaser in operating control of the Assets.

          10.1  Indemnification by the Seller and the Shareholders.
                ---------------------------------------------------

          From and after the Closing, but for a period limited to two years
after the Closing (except for claims, damages, losses, liabilities and
deficiencies relating to Environmental Conditions, Taxes and employment-related
matters which shall have no time limitation), the Seller and each of the
Shareholders shall, jointly and severally, provided, however, the Shareholders
(whether individually or in the aggregate) shall not be personally liable for
any indemnification of Purchaser for any amount greater than the Purchase Price
(except for indemnifications for Environmental Conditions which shall have no
monetary limitation) reimburse and indemnify and hold Purchaser, its affiliates
and its and their respective directors, officers, agents, employees, successors
and assigns (each, an "Indemnified Purchaser Party") harmless against and in
respect of:

          (a) any and all damage, loss, liability or deficiency resulting from
any misrepresentation, breach or failure of warranty or representation or
nonfulfillment of any covenant or agreement on the part of the Seller or the
Shareholders under this Agreement or from any misrepresentation in or omission
from any certificate or other instrument furnished to Purchaser by the Seller or
any Shareholder pursuant to this Agreement, including, but not limited to,
breach or failure of any warranty or representation under Section 3.7(b)
relating to Environmental Conditions;

          (b) any and all Liabilities of the Seller of any nature whatsoever,
including without limitation any and all federal, state or local tax assessments
that relate to the Seller or arise out of the conduct of the Business prior to
the Closing Date other than Assumed Liabilities;

          (c) any and all damage, loss, liability or deficiency resulting from
the Seller's failure to comply with the bulk sales law and other similar laws in
any applicable jurisdiction in respect of the transactions contemplated by this

                                      37
<PAGE>
 
Agreement and any action brought or levy made as a result thereof, and

          (d) any and all actions, suits, claims, proceedings, investigations,
audits, demands, assessments, fines, judgments, settlements, costs and other
expenses (including, without limitation, reasonable audit and legal fees)
incident to any of the foregoing.

Notwithstanding the foregoing, no indemnification is provided hereunder except
for costs, damage, loss, claims or liabilities incident to (a) - (d) above,
which in the aggregate total more than $25,000, at which point Seller shall be
obligated only to indemnify the Purchaser from and against further such costs,
damage, loss, claims or liabilities in excess of $25,000 in the aggregate. It is
further acknowledged by Purchaser that notwithstanding any survival of any
covenant herein, it shall not seek any indemnification by Seller after the
termination of any limitation period provided above.

          10.2.  Purchaser's Method of Asserting Claims.
                 ---------------------------------------

          Except as provided otherwise in Section 9.3(c), all claims for
indemnification by an Indemnified Purchaser Party under this Agreement shall be
asserted and resolved as follows:

          (a) In the event that any claim or demand for which the Seller or the
Shareholders would be liable to an Indemnified Purchaser Party hereunder is
asserted against or sought to be collected from an Indemnified Purchaser Party
by a third party, the Indemnified Purchaser Party shall promptly notify the
Purchaser of such claim or demand, specifying the nature of such claim or demand
(the "Claim Notice"). The Seller shall have 30 days from the personal delivery
or mailing of the Claim Notice (the "Notice Period") to notify the Indemnified
Purchaser Party whether or not the Seller or the Shareholders desire, at their
sole cost and expense, to defend the Indemnified Purchaser Party against such
claim or demand. If the Seller notifies the Indemnified Purchaser Party within
the Notice Period that the Seller and the Shareholders desire to defend the
Indemnified Purchaser Party against such claim or demand, except as hereinafter
provided, the Seller or the Shareholders shall have the right to defend the
Indemnified Purchaser Party by appropriate proceedings, and with counsel
reasonably acceptable to Purchaser, which proceedings shall be promptly settled
or prosecuted to a final conclusion; provided, however, that the Seller and the
Shareholders shall reimburse and indemnify, and hold the Indemnified Purchaser
Party harmless against and in respect of any and all damages arising out of any
such settlement or final conclusion. If the Indemnified Purchaser Party desires
to participate in, but not control, any such defense or settlement it may do so
at its sole cost and expense. If, in the reasonable opinion of the Indemnified
Purchaser Party, any such claim or demand involves an issue or matter which
could have a materially adverse effect on the business, operations, assets,


                                      38
<PAGE>
 
properties or prospects of the Indemnified Purchaser Party, or if there exists
any conflict of interest between the position of any Indemnified Purchaser Party
and Seller or any Shareholder, the Indemnified Purchaser Party shall have the
right to control the defense or settlement of any such claim or demand,  and its
reasonable costs and expenses shall be included as part of the indemnification
obligations of the Seller and the Shareholders hereunder.  If the Seller and
Selling Shareholders elect not to defend the Indemnified Purchaser Party against
such claim or demand, whether by not giving Indemnified Purchaser Party timely
notice as provided above or otherwise, then the amount of any such claim or
demand, or, if the same be contested by the Seller or by the Indemnified
Purchaser Party (but the Indemnified Purchaser Party shall not have any
obligation to do so), then that portion thereof as to which such defense is
unsuccessful,  shall be conclusively deemed to be a liability of the Seller and
the Shareholders hereunder.

          (b) If an Indemnified Purchaser Party should have a claim against the
Seller or the Shareholders hereunder which does not involve a claim or demand
being asserted against or sought to be collected from it by a third party, the
Indemnified Purchaser Party shall promptly send a Claim Notice with respect to
such Claim to the Seller. If the Seller does not notify the Indemnified
Purchaser Party within the Notice Period that the Seller or the Shareholders
dispute such claim, the amount of such claim shall be conclusively deemed a
liability of Seller and the Shareholders hereunder.

          (c) Seller, Robert R. Romano and Wayne R. Ewald, hereby designates,
appoints and authorizes Robert R. Romano, and Kenneth J. Moore hereby
designates, appoints and authorizes Kenneth J. Moore, respectively as his or its
attorney-in-fact to take such actions on his or its behalf on all matters
related to all indemnification claims under Section 10 hereof, and to receive
and respond to all notices delivered in connection herewith.

          10.3  Indemnification by the Purchaser.
                ---------------------------------

          From and after the Closing, for a period limited to two years after
the Closing, the Purchaser shall, reimburse and indemnify and hold the
Shareholders and the Seller, its affiliates and its and their respective
directors, officers, agents, employees, successors and assigns (each, an
"Indemnified Seller Party") harmless against and in respect of the following,
provided however, that the Purchaser shall not in any event be liable for any
indemnification of the Seller or any Shareholders for any amount greater than
the Purchase Price:

                (a) any and all damage, loss, liability or deficiency resulting
from any misrepresentation, breach or failure of warranty or representation or
nonfulfillment of any covenant or agreement on the part of the Purchaser under
this Agreement or from any misrepresentation in or omission from any certificate
or other

                                      39
<PAGE>
 
instrument furnished to Seller by the Purchaser pursuant to this Agreement;

                (b) any and all actions, suits, claims, proceedings,
investigations, audits, demands, assessments, fines, judgments, settlements,
costs and other expenses (including, without limitation, reasonable audit and
legal fees) incident to any of the foregoing.

Notwithstanding the foregoing, no indemnification is provided hereunder except
for costs, damage, loss, claims or liabilities incident to (a)-(b) above, which
in the aggregate total more than $25,000, at which point Seller shall be
obligated only to indemnify the Purchaser from and against such further costs,
damage, loss, claims or liabilities in excess of $25,000 in the aggregate. It is
further acknowledged by Purchaser that notwithstanding any survival of any
covenant herein, it shall not seek any indemnification by Seller after the
termination of any limitation period provided above.

          10.4.  Seller's Method of Asserting Claims.
                 ------------------------------------

          All claims for indemnification by an Indemnified Seller Party under
this Agreement shall be asserted and resolved as follows:

                 (a) In the event that any claim or demand for which the
Purchaser would be liable to an Indemnified Seller Party hereunder is asserted
against or sought to be collected from an Indemnified Seller Party by a third
party, the Indemnified Seller Party shall promptly notify the Purchaser of such
claim or demand, specifying the nature of such claim or demand (the "Claim
Notice"). The Purchaser shall have 30 days from the personal delivery or
mailing of the Claim Notice (the "Notice Period") to notify the Indemnified
Seller Party whether or not the Purchaser desires, at its sole cost and expense,
to defend the Indemnified Seller Party against such claim or demand. If the
Purchaser notifies the Indemnified Seller Party within the Notice Period that
the Purchaser desires to defend the Indemnified Seller Party against such claim
or demand, except as hereinafter provided, the Purchaser shall have the right to
defend the Indemnified Seller Party by appropriate proceedings, and with counsel
reasonably acceptable to Seller, which proceedings shall be promptly settled or
prosecuted to a final conclusion; provided, however, that the Purchaser shall
reimburse and indemnify, and hold the Indemnified Seller Party harmless against
and in respect of any and all damages arising out of any such settlement or
final conclusion. If the Indemnified Seller Party desires to participate in, but
not control, any such defense or settlement it may do so at its sole cost and
expense. If, in the reasonable opinion of the Indemnified Seller Party, any such
claim or demand involves an issue or matter which could have a materially
adverse effect on the business, operations, assets, properties or prospects of
the Indemnified Seller Party, or if there exists any conflict of interest
between the position of any

                                      40
<PAGE>
 
Indemnified Seller Party and Purchaser, the Indemnified Seller Party shall have
the right to control the defense or settlement of any such claim or demand, and
its reasonable costs and expenses shall be included as part of the
indemnification obligations of the Purchaser hereunder. If the Purchaser elects
not to defend the Indemnified Seller Party against such claim or demand, whether
by not giving Indemnified Seller Party timely notice as provided above or
otherwise, then the amount of any such claim or demand, or, if the same be
contested by the Purchaser or by the Indemnified Seller Party (but the
Indemnified Seller Party shall not have any obligation to do so), then that
portion thereof as to which such defense is unsuccessful, shall be conclusively
deemed to be a liability of the Purchaser hereunder.

                (b) If an Indemnified Seller Party should have a claim against
the Purchaser hereunder which does not involve a claim or demand being asserted
against or sought to be collected from it by a third party, the Indemnified
Seller Party shall promptly send a Claim Notice with respect to such Claim to
the Purchaser. If the Purchaser does not notify the Indemnified Seller Party
within the Notice Period that the Purchaser disputes such claim, the amount of
such claim shall be conclusively deemed a liability of Purchaser hereunder.

                (c) Purchaser hereby designates, appoints and authorizes Ronald
H. Donati as its attorney-in-fact to takes such actions on his or its behalf on
all matters related to all indemnification claims under Section 10 hereof, and
to receive and respond to all notices delivered in connection herewith.

          10.5.  Other Rights and Remedies Not Affected.
                 ---------------------------------------

          The indemnification rights of the parties under this Section 10 are
independent of and in addition to such rights and remedies as the parties may
have at law or in equity or otherwise for any actions for fraud, including
without limitation the right to seek specific performance, rescission or
restitution, none of which rights or remedies shall be affected or diminished
hereby.

          11.  Survival of Representations and Warranties.
               -------------------------------------------

          All representations and warranties made by the Seller and the
Shareholders in this Agreement or pursuant hereto shall survive the Closing to
the extent of the indemnification periods set forth in Section 10.1.
Notwithstanding any investigation, due diligence or audit conducted before or
after the Closing Date by or on behalf of Purchaser or the decision of Purchaser
to complete the Closing, Purchaser shall be entitled to rely upon the
representations, warranties and agreements set forth herein or pursuant hereto.

          12.  Compliance with Bulk Sales Laws.
               --------------------------------

          Seller shall furnish to Purchaser a true and complete list of its
existing creditors prepared and sworn to as provided in

                                      41
<PAGE>
 
Section 6-104 of the Massachusetts Bulk Transfers Law ("Section 6-104").
Purchaser shall have the right to give notice of the transfer to such creditors
and any other creditors known to Purchaser. Seller shall take all steps
necessary or appropriate to enable Purchaser to comply with the Massachusetts
Bulk Transfers Law should Purchaser decide to do so, including preparation of
the schedule of property transferred under Section 6-104.

          13.   Additional Matters.
                -------------------

          13.1  Employee Benefits.
                ------------------

          (a) The Seller shall pay directly to each employee of the Seller all
benefits accrued on behalf of that employee (or attributable to expenses
properly incurred by that employee), provided, however, that such employees may
elect to carryover such accrued and unused vacation days as are consistent with
Seller's practices, as of the Closing Date which are not assumed by Purchaser
under this Agreement. No portion of the assets of any plan, fund, program or
arrangement, written or unwritten, heretofore sponsored or maintained by the
Seller (and no amount attributable to any such plan, fund, program or
arrangement) shall be transferred to the Purchaser, and the Purchaser shall not
be required to continue any such plan, fund, program or arrangement after the
Closing Date. The amounts payable on account of all benefit arrangements (other
than as specified in the following subsections) shall be determined with
reference to the date of the event by reason of which such amounts become
payable, without regard to conditions subsequent, and Purchaser shall not be
liable for any claim for insurance, reimbursement or other benefits payable by
reason of any event which occurs prior to, through and including the Closing
Date.

                (b) All amounts, if any, payable directly to employees, or to
any fund, program, arrangement or plan maintained by the Seller shall be paid by
the Seller within 30 days after the Closing Date; provided, however, that if any
Hired Employee (as defined in Section 13.2 hereof) is entitled to accrued
vacation time as of the Closing Date, the Purchaser shall credit such Hired
Employee with such accrued vacation time earned as of the Closing until December
31, 1996, but not thereafter. All employees of the Seller who are employed by
the Purchaser on or after the Closing Date shall be new employees of the
Purchaser and any prior employment by the Seller of such employees shall not
affect entitlement to, or the amount of, salary or other cash compensation,
current or deferred, which the Purchaser may make available to its employees,
provided, however, that for purposes of eligibility and vesting in Purchaser's
401(k) plan and determining seniority for paid vacation, Purchaser will give
Hired Employees full credit for years of service with Seller.

               (c) Except as provided above, from the Closing Date until
December 31, 1996, Purchaser will provide Hired Employees

                                      42
<PAGE>
 
with the same employment benefits they received while employees of Seller,
subject to the following limitations:

                   (i)    Purchaser's obligation to maintain medical, dental,
and life insurance shall be conditioned upon Purchaser's ability to assume
Seller's rights under such existing contracts of insurance;

                   (ii)   Purchaser will not continue to offer Hired Employees
the ability to participate in any 401(k), retirement, profit-sharing, or pension
plan maintained by Seller prior to the Closing Date. Purchaser will, however,
allow Hired Employees to transfer vested balances in profit sharing or 401(k)
plans maintained by Seller to 401(k) accounts established with Purchaser.
Purchaser furthermore agrees to give Hired Employees full credit for years of
service with Seller for purposes of eligibility to participate and vesting in
Purchaser's 401(k) Plan.

          (d) At Purchaser's request, Seller will use its best efforts to permit
Purchaser to assume at and after Closing its rights under its worker's
compensation insurance plan after Closing.

          13.2.  Employees.
                 ----------

                 (a) As of the Closing Date, the Purchaser may, at its option,
offer employment to, and the Seller shall use its best efforts to assist the
Purchaser in employing as new employees of Purchaser, all persons presently
engaged in the Business who are identified by Purchaser prior to the Closing
Date (the "Hired Employees"). The Seller shall terminate effective as of the
Closing Date all employment agreements it has with any of the Hired Employees,
and shall assign to the Purchaser the benefit of any secrecy or confidentiality
agreements it has with any of the Hired Employees. The Purchaser assumes
liability for any act or omission relating to the employment of Hired Employees
which occurs after the Closing.

                 (b) Until the third anniversary of the Closing Date, neither
the Seller nor any of the Shareholders will directly or indirectly solicit or
offer employment to or employ any Hired Employee (a) who is then an employee of
the Purchaser, or (b) who has terminated such employment without the consent of
the Purchaser within 180 days of such proposed solicitation or offer. The
remedial provisions of Section 8 as applicable to Seller shall apply to the
provisions of this Section 13.2(b) as to the Seller and each Shareholder and
they are hereby incorporated by reference.

          13.3.  Discharge of Business Obligations.
                 ----------------------------------

          From and after the Closing Date, the Seller shall pay and discharge,
on a timely basis, all Liabilities incurred prior to the Closing Date in respect
of the Business or the Assets other than the Assumed Liabilities,  its
operations  or  the  assets  and

                                      43
<PAGE>
 
properties used therein, including without limitation any Liabilities to
employees.

          13.4  Maintenance of Financial Records.
                ---------------------------------

          The Seller will maintain, and will make available to the Purchaser
promptly upon request, all financial records and data as may reasonably be
necessary for preparation of audited financial statements of the Seller for
fiscal years through the Closing Date.

          13.5  Non-Use of Name.
                ----------------

          From and after the Closing Date, Seller and Shareholders agree not to
use, or grant any Third Party the right to use, the name "Alternate Circuit
Technology."

          14.  Brokerage; Expenses.
               --------------------

               (a) The parties hereto represent and warrant that except for
Purchaser's representative Gateway Advisors, Inc. and Seller's brokers, Geneva

documentary and other transfer taxes, if any, due as a result of the purchase,
sale or transfer of the Assets in accordance herewith whether imposed by law on
the Seller or the Purchaser, and the Seller shall indemnify, reimburse and hold
harmless the Purchaser in respect of the liability for payment of or failure to

United States Mail or nationally recognized courier service properly addressed
to the appropriate party. Notice shall be deemed to have been given when

          17.  Termination.
               ------------

          17.1.  Basis for Termination.
                 ----------------------

          This Agreement may be terminated by notice of termination at any time
prior to the Closing Date only as follows:

               (a) by mutual consent of the Seller and the Purchaser;

               (b) by the Purchaser, upon written notice to the Seller given at
any time before the date set forth in Section 6.9 (or as extended in accordance
thereof) if any of the conditions

                                      46
<PAGE>
 
precedent set forth in Section 6 hereof have not been materially fulfilled;

                (c)   by the Seller, upon written notice to the Purchaser given 
at any time before Closing if any of the conditions precedent set forth in
Section 7 hereof have not been fulfilled.

          17.2.  Liquidated Damages to Purchaser.
                 --------------------------------

          The parties acknowledge that if Seller sells, transfers or negotiates
to sell or transfer any of its assets except in the ordinary course of business
with a person or entity other than Purchaser before the Closing, Purchaser will
suffer damages as a result of the costs and expenses incurred in connection with
the acquisition described herein and will be entitled to reimbursement of such
amount. Because it would be difficult to determine the exact amount of such
damage, the parties agree that Seller shall pay to Purchaser $250,000, which the
parties agree is a reasonable estimate of Purchaser's costs and damages. Such
damages shall be Purchaser's sole remedy at law, equity or otherwise with
respect to any breach of this Agreement by Seller which results in a failure to
close this agreement as contemplated in Section 9.

          17.3.  Effect of Termination.
                 ----------------------

          If this Agreement is terminated under Section 17.1, this Agreement
shall become void and have no further effect, without any Liabilities on the
part of any party hereto, unless the termination was based on the
representations and warranties of a party being materially incorrect when made
or the material breach by such party of a covenant hereunder, in which event the
party whose representations and warranties were incorrect or who breached such
covenant shall be liable to the other party for all costs and expenses of the
other party in connection with the preparation, negotiation, execution and
performance of this Agreement and the other transaction documents contemplated
hereby.

          18.  Provisions Not Construed Against Party Drafting Agreement.
               ----------------------------------------------------------

          This Agreement shall be deemed to have been drafted by all parties
and, in the event of a dispute, no party hereto shall be entitled to claim that
any provision should be construed against any other party by reason of the fact
that it was drafted by one particular party.

                                      47

          19.  Governing Law.
               --------------

          This Agreement shall be construed and interpreted in accordance with
the laws of the Commonwealth of Massachusetts without regard to its provisions
concerning conflict of laws.

          20.  Section Headings.
               -----------------

          The various section headings are inserted for convenience of reference
only and shall not affect the meaning or interpretation of this Agreement or any
section thereof.

          21.  Counterparts.
               -------------

          This Agreement may be executed in any number of counterparts, each of

     WHEREAS, on June 7, 1996, Zycon Corporation, a Delaware corporation (the

     NOW, THEREFORE, the parties agree as follows:

     Section 6.9 of the Agreement is hereby amended to read in full as follows:

          Purchaser shall be satisfied, in its reasonable discretion, with the

                 SECOND AMENDMENT TO ASSET PURCHASE AGREEMENT

       WHEREAS, on June 7, 1996, Zycon Corporation, a Delaware corporation (the 
"Purchaser"), Alternate Circuit Technology, Inc., a Massachusetts corporation 
(the "Seller"), and each of the shareholders of Seller (the "Shareholders") 
executed an Asset Purchase Agreement (the "Agreement"), pursuant to which the 
Purchaser will purchase certain assets of Seller.

       NOW, THEREFORE, the parties agree as follows:

       1.  Purchaser waives the need to produce item five on Schedule 6.5.

       2.  Purchaser waives the requirement that Seller produce, at Closing, a 
UCC-3 termination statement from CIT Group/Equipment Financing, Inc. based upon 
receipt of CIT letters committing to execute such termination statement dated 
June 14, 1996 and June 17, 1996.

       3.  Because the good standing certificate and waiver of tax lien for 
Seller issued by the MA Department of Revenue has not been received at the time 
of Closing, Purchaser waives production of such document at Closing, provided 
however, that until such certificate is issued, no funds will be released to 
Seller from the escrow.

       4.  The parties modify Section 9.3 of the Agreement to provide that, at 
Closing, the parties have not adjusted the Purchase Price; however neither of 
the parties waives the right to have such adjustment made by the accountants as 
more specifically set forth in paragraph 9.3(c).

       5.  Schedules 1.1(a), 1.1(b), and 1.2 are amended to exclude from the 
Assets acquired and the Liabilities Assumed the Manufacturer's Agreement between
ACT and ISYS Engineering effective March 14, 1996 unless ISYS agrees to a 
modification of the agreement satisfactory to Zycon.

       6.  Purchaser waives the requirement that Seller produce at Closing 
assignments and UCC-3 modifications for a lease held by ICON Cash Flow Partners,
L.P.  The parties agree to endeavor to complete the assignment promptly after 
closing.

       7.  The parties modify Paragraphs 6.12, 9 and other schedules or 
provisions of the Agreement as necessary to conform to the following:  Purchaser
has elected to pay off the Seller's indebtedness to GE Capital Public Finance 
and MIFA under the MIFA Lease Financing.  Purchaser waives and forgoes any 
benefit to it resulting from the loss of the favorable interest rate on such 
financing and shall bear $12,000 of the prepayment penalty resulting from such 
payoff.  seller shall bear the balance of the prepayment penalty.  To effectuate
such transaction, Seller and Purchaser shall cause the release of $100,000 of 
the $850,000 funds heretofore deposited to escrow at State Street Bank and Trust
Company as follows: to Zycon $34,802.40; to ACT $65,197.60.

        IN WITNESS WHEREOF, this Second Amendment to Asset Purchase Agreement 
has been executed by the parties hereto as of this 18th day of June, 1996.

          (b) If a Shareholder delivers a written notice to the Company, within
     15 days after delivery of the foregoing notice, of his desire to have any
     of the Shares included in a Company Registration Statement, such Shares
     shall be included in any Company Registration Statement so filed, subject
     to the other provisions of this Agreement.

          (c) The Company shall have no obligation to effect registration if all
     of the Shareholder's Shares requested to be registered shall be in the
     written opinion of counsel to the Company, addressed to the Shareholder,
     eligible to be sold to the public without registration under the 1933 Act
     and without restriction as to subsequent trading.

          (d) If an underwriter with respect to a Company Registration Statement
     (the "Underwriter") advises the Company that the number of shares proposed
     to be sold by the Company and the Shareholders is greater than the number
     of Shares of common stock which the Underwriter believes feasible to sell
     at that time, at the price and upon the terms approved by the Company, then
     the number of Shares of common stock which the Underwriter in its sole
     discretion believes may be sold shall first be allocated to the Company and
     the remaining number of such Shares of common stock shall then be allocated
     on a pro rata basis to all other holders of common stock being registered,
     including the Shareholders.  In the event a Shareholder is unable to sell
     such of his Shares as he desires to sell in a Company Registration
     Statement due to restrictions or advice to the Company from the
     Underwriter, such Shareholder will not be deemed to have exercised his
     right to have Shares included in a Company Registration Statement to the
     extent his Shares are excluded.

          (e) At the request of the Underwriter, and as a condition to inclusion
     in the Company Registration Statement of any Shares owned by the
     Shareholders, the Shareholders shall agree in writing not to offer or sell
     any Shares not sold pursuant to a Company Registration Statement filed
     pursuant to this Agreement for a period specified by the Underwriter,
     provided that such period shall not exceed 180 days from the effective date
     of such Company Registration Statement and that every other selling
     shareholder subject to a provision identical or substantially similar to
     this paragraph (e) is similarly restricted.

          (f) Notwithstanding the inclusion of any Shares owned by the
     Shareholders in any Company Registration Statement filed pursuant to this

                                       2
<PAGE>
 
     Agreement, the Company shall have no obligation to cause or permit such
     Company Registration Statement to become effective under the 1933 Act at
     any time, and in its sole discretion may withdraw such Company Registration
     Statement at any time prior to the effectiveness thereof for any reason
     whatsoever.  The Company agrees in the event of any such withdrawal of any
     Company Registration Statement to give prompt notice of such withdrawal to
     the Shareholders.  In the event of such withdrawal the Shareholders will
     not be deemed to have exercised their right to have Shares included in a
     Company Registration Statement so withdrawn.

          (g) The Company shall be obligated to cause any effective prospectus
     included in the Company Registration Statement to meet the requirements of
     Section 10 of the 1933 Act for a period of ninety (90) days from the date
     on which the Shareholders were first able to sell Shares pursuant to such
     Company Registration Statement provided, however, that if, as a result of
     interruptions in the offer and sale of Shares covered thereby, the
     aggregate period for which the Shareholders were able to offer and sell
     their Shares pursuant to such Company Registration Statement would be
     reduced to less than 90 days, the Company shall take such action as may be
     necessary to enable the Shareholders to continue such offer and sale for an
     additional period or periods sufficient to produce an aggregate offering
     period of 90 days.

     2.  Selling Expenses.
         ---------------- 

          (a) Except as otherwise set forth in (b) below or as required by the
     SEC or any other federal or state regulatory authority, the costs and
     expenses incurred in connection with the inclusion of the Shareholders'
     Shares in a registration statement shall be borne by the Company with
     respect to any Company Registration Statement filed under this Agreement
     which includes Shares of the Shareholders, including, without limitation,
     all costs and expenses arising from or related to the preparation and
     filing of such registration statements, the prosecution of such filings to
     effectiveness and the maintenance of such registration statements in effect
     for the period determined pursuant to this Agreement.

          (b) Notwithstanding anything to the contrary set forth in subsection
     (a), the Shareholders shall bear the following costs and expenses incurred
     in connection with all registration statements filed pursuant to this
     Agreement in which Shares owned by them are included:

                                       3
<PAGE>
 
               (i)   The fees and disbursements of any separate counsel retained
               by any of the Shareholders;

               (ii)  Any underwriting discounts, commissions and expenses
               relating to Shares sold by the Shareholders; and

               (iii) Any taxes payable with respect to the transfer by the 
               Shareholders.

          (c) Notwithstanding anything to the contrary set forth herein, the
     Company shall have no obligation to bear such fees in connection with the
     inclusion of Shares in a Company Registration Statement in any states where
     the Company was not otherwise intending to register or file with respect to
     shares covered by the Company Registration Statement.

     3.   Reports Under Securities Exchange Act of 1934.  With a view to making
          ---------------------------------------------                        
available to the Shareholders the benefits of Rule 144 promulgated under the
1933 Act and any other rule or regulation of the SEC that may at any time permit
the Shareholders to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3 (or any successor form to
Form S-3 regardless of its designation), the Company agrees to use reasonable
efforts to:

          (a) make and keep public information available, as those terms are
     understood and defined in SEC Rule 144, at all times;

          (b) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Act and the Securities Exchange
     Act of 1934, as amended (the "1934 Act"); and

          (c) furnish to the Shareholders, so long as the Shareholders own any
     Shares, forthwith upon request, whenever applicable (i) a written statement
     by the Company that it has complied with the reporting requirements of SEC
     Rule 144, the 1933 Act, and the 1934 Act, or that it qualifies as a
     registrant whose securities may be resold pursuant to Form S-3 (at any time
     after it so qualifies), (ii) a copy of the most recent annual or quarterly
     report of the Company and such other reports and documents so filed by the
     Company, and (iii) such other information as may be reasonably requested in
     availing the Shareholders of any rule or regulation of the SEC which
     permits the selling of any such securities without registration or pursuant
     to such form.

     4.   Indemnification.  In the event any of the Shares are included in any
          ---------------                                                     
registration statement:

                                       4
<PAGE>
 
          (a) the Company shall indemnify and hold harmless the Shareholders or
     any underwriter (within the meaning of the 1933 Act) for the Company or the
     Shareholders, against any losses, claims, damages or liabilities, joint or
     several, to which they may become subject under the 1933 Act, or the 1934
     Act, state securities laws, other federal or state law or regulation, at
     common law or otherwise, insofar as such losses, claims, damages or
     liabilities (or actions in respect thereof) (i) arise out of or are based
     upon any untrue or alleged untrue statement of any material fact contained
     in such registration statement, including any preliminary prospectus or
     final prospectus contained therein or any amendments or supplements thereto
     or any documents prepared or furnished by the Company incident thereto, or
     (ii) 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
     to make the statements therein not misleading, or (iii) arise out of or are
     based upon any violation by the Company of any rule or regulation
     promulgated under the 1933 Act, the 1934 Act, or other federal or state law
     applicable to the Company and relating to any action or inaction required
     of the Company in connection with such registration. The Company shall
     reimburse the Shareholders or such underwriter for any reasonable and
     actual legal or other expenses, as incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability or
     action. Notwithstanding the foregoing, the Company shall not be liable in
     any such case for any loss, claim, damage, liability or action to the
     extent that it arises out of or is based upon an untrue statement or
     alleged untrue statement or omission or alleged omission made in connection
     with such registration statement, preliminary prospectus, final prospectus
     or amendments or supplements thereto or documents prepared or furnished by
     the Company incident thereto in reliance upon and in conformity with
     information furnished expressly for use in connection with such
     registration by any of the Shareholders or such underwriter.

          (b) each Shareholder shall indemnify and hold harmless the Company,
     each of its directors, each of its officers who have signed such
     registration statement, each person, if any, who controls the Company
     within the meaning of the 1933 Act or the 1934 Act, any underwriter for the
     Company (within the meaning of the 1933 Act) and each other holder and its
     respective officers, directors, partners and controlling persons to the
     same extent as the foregoing indemnity from the Company to the
     Shareholders, in each case to the same extent, but only to the extent, that
     such untrue statement or alleged untrue statement or omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading was made in such
     registration statement,
    
                                       5
 
<PAGE>
 
     preliminary prospectus, final prospectus or amendments or supplements
     thereto or document prepared or furnished by the Company incident thereto
     in reliance upon and in conformity with information furnished by such
     Shareholder expressly for use in connection with such registration.

          (c) promptly after receipt by an indemnified party under this section
     of notice of the commencement of any action, such indemnified party shall,
     if a claim in respect thereof is to be made against any indemnifying party
     under this Section, notify the indemnifying party in writing of the
     commencement thereof; but the omission so to notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party unless such liability is the proximate result of such failure.  In
     case any such action is brought against any indemnified party, and it
     notifies the indemnifying party of the commencement thereof, the
     indemnifying party will be entitled to appoint counsel reasonably
     satisfactory to such indemnified party to represent the indemnified party
     in such action; provided, however, that if the defendants in any such
     action include both the indemnified party and the indemnifying party and
     the indemnified party shall have reasonably concluded based on the written
     opinion of counsel addressed to the indemnifying party that there may be a
     conflict of interest between it and/or other indemnified parties, on the
     one hand, and the indemnifying party, on the other, the indemnified party
     or parties shall have the right to select separate counsel to defend such
     action on behalf of such indemnified party or parties.  Upon receipt of
     notice from the indemnifying party to such indemnified party of its
     election so to appoint counsel to defend such action and approval by the
     indemnified party of such counsel, the indemnifying party will not be
     liable to such indemnified party under this section for any legal or other
     expenses subsequently incurred by such indemnified party in connection with
     the defense thereof unless (i) the indemnified party shall have employed
     separate counsel in accordance with the proviso to the next preceding
     sentence (it being understood, however, the indemnifying party shall not be
     liable for the expenses of more than one separate counsel for all
     Shareholders), or (ii) the indemnifying party shall not have employed
     counsel reasonably satisfactory to the indemnified party to represent the
     indemnified party within a reasonable time after notice of commencement of
     the action.

          (d) In order to provide for just and equitable contribution in
     circumstances in which the indemnification provided for in paragraph (a) or
     (b) of this Section 4 is due in accordance with its terms but is for any
     reason held by a court to be unavailable from the Company on grounds of
     policy or otherwise, the Company and the Shareholders shall contribute to
     the aggregate losses, claims, damages and liabilities (including legal or
     other

                                       6
<PAGE>

     expenses reasonably incurred in connection with investigating or defending
     same) to which the Company and the Shareholders may be subject in such
     proportions as is appropriate to reflect the relative fault of the
     indemnifying party on the one hand of the indemnified party on the other in
     connection with the statements or omissions which resulted in such loss,
     liability, claim, damage or expense as well as any other equitable
     considerations. The relative fault of the indemnifying party and of the
     indemnified party shall be determined by a court of law by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission to state a material fact relates to
     information supplied by the indemnifying party or by the indemnified party
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement of omission. Any party
     entitled to contribution will, promptly after receipt of notice of
     commencement of any action, suit or proceeding against such party in
     respect of which a claim for contribution may be made against another party
     or parties under this paragraph (d), notify such party or parties from whom
     contribution may be sought, but the omission to so notify such party or
     parties shall not relieve the party or parties from whom contribution may
     be sought from any other obligation it or they may have hereunder or
     otherwise than under this paragraph (d).

     5.   Limitation and Expiration of Piggyback Registration Rights.
          ----------------------------------------------------------  
Notwithstanding anything to the contrary herein, the foregoing rights may be
exercised once by each Shareholder, and not later than two (2) years from the
Closing Date as defined in the Asset Purchase Agreement between the Company and
ACT.


     IN WITNESS WHEREOF, the undersigned have executed this Registration Rights
Agreement as of the date first above written.

     If the "cost of living" has increased as shown by the Consumer Price Index
     (Boston, Massachusetts, All Items, All Urban Consumers, Base Year = 1967,
     United States Bureau of Labor Statistics), then the amount of the base rent
     due hereunder during each calendar year of this Lease and any extensions
     thereof shall be annually adjusted in proportion to any increase in the

     each year during the lease term. The base month from which to determine the
     amount of each increase in the Index shall be N/A which figure shall be

     percentage increase, if any, in the base rent to be paid during the
     following calendar year. In no event, however, shall the base rental rate,
     as adjusted, be less than the base rent stated hereinabove. In the event
     that the publication of the Consumer Price Index as presently computed is
     discontinued as a measure of "cost of living" for any reason, then Lessor
     shall designate a comparable alternate index then in general use to compute
     such rental adjustment as provided herein.

     In the event that, (A) Lessee shall be declared bankrupt or insolvent
     according to law, or if any assignment shall be made of Lessee's property
     for the benefit of creditors or, (B) Lessee shall default in the payment of
     his security deposit or any installment of rent or of any invoice for goods
     or services or other sums herein specified and such default shall continue
     for ten (10) days after written notice thereof, or (C) Lessee shall default
     in the observance or performance of any other of Lessee's covenants,
     agreements or obligations hereunder and the effect of any such default
     shall not have been cured or Lessee shall not have commenced and diligently
     prosecuted the same at all times thereafter within thirty (30) days after
     written notice of default from the Lessor, or (D) Lessee vacates the
     premises or permits them to be unoccupied

                                     -14-
<PAGE>
 
     for more than then (10) days, then Lessor shall have the right thereafter
     while such default continues, and without demand or further notice, to re-
     enter and take complete possession of the leased premises, to declare the
     term of this Lease ended and to remove Lessee's effects without being
     guilty of any manner of trespass and without prejudice to any remedies
     which might be otherwise used for arrears of rent or other default or
     breach of covenant.  Lessee shall indemnify Lessor against all loss of rent
     and other payments which Lessor may incur by reason of such termination
     during the remainder of the term.  If Lessee shall default, in the
     observance or performance of any conditions or covenants on Lessee's part
     to be observed or performed under or by virtue of any of the provisions in
     any Article of this Lease, Lessor, upon ten (10) days written notice to
     Lessee, without being under any obligation to do so and without thereby
     waiving such default, may remedy the same for the account of and at the
     expense of Lessee.  If Lessor pays or incurs any obligations for the
     payment of money in connection therewith, including, but not limited to,
     reasonable attorney's fees in instituting, prosecuting or defending any
     action or proceeding, such sums paid or obligations incurred, with interest
     at the rate of eighteen (18%) percent per annum and costs, shall be paid to
     Lessor by Lessee as additional rent.  Upon default of this Lease by Lessee,
     and because the payment of rent in monthly installments is for the sole
     convenience of Lessee, the entire balance of rent which will accrue
     hereunder shall at the option of the Lessor become immediately due and
     payable.  Lessee further agrees to pay all reasonable attorney's fees
     incurred by Lessor in enforcing any and all obligations of Lessee under
     this Lease at any time.

25.  NOTICE
     ------
     All notices or other communications shall be deemed given and delivered to
     the respective parties three (3) days after mailed, by registered or
     certified mail, postage and registration or certification charges prepaid,
     addressed to the parties at the addresses set forth hereinabove, except
     that either party may, by written notice to the other, designate another
     address which shall thereupon become the effective address of such party
     for the purposes of this paragraph.

26.  OCCUPANCY
     ---------
     In the event that Lessee takes possession of said premises prior to the
     commencement of the term of this Lease, Lessee covenants and agrees to
     perform and observe all of Lessee's covenants herein from the date upon
     which Lessee takes possession except its obligation for the payment of
     additional rents for any period of less than one month.  In the event that
     Lessee remains after the agreed expiration date of this Lease without the
     written permission of Lessor, then all other terms of this Lease shall
     continue to apply except that Lessee shall be liable to Lessor, and rent
     shall be due in monthly installments at a rate of one hundred and fifty
     (150%) percent of that which would otherwise be due under this Lease, it
     being understood between the parties that such extended occupancy as a
     tenant at sufferance is solely for the benefit and convenience of Lessee
     and as such has greater value.

27.  FIRE PREVENTION
     ---------------
     Lessee agrees to use every reasonable precaution against fire and agrees to
     provide and maintain approved, labelled fire extinguishers and emergency
     lighting equipment within

                                     -16-

28.  OUTSIDE AREA

     No goods or things of any type or description shall be held or stored
     outside the leased premises at any time without the express written
     approval of Lessor.

29.  ENVIRONMENT
     -----------
     Lessee will so conduct and operate the leased premises as not to interfere
     in any manner with the use and enjoyment of other portions of the same or
     neighboring buildings by other by reason of odors, smells, noise,
     accumulation of garbage or trash, vermin or other pests or otherwise and
     will at its expense employ a professional pest control service if
     necessary.  Lessee agrees to maintain efficient and effective devices for
     preventing damage to heating equipment from harmful solvents, degreasers,
     cutting oils, and similar substances which may be used within the premises.
     No hazardous waste or chemical waste of any sort shall be stored or allowed
     to remain within the leased premises at any time.

30.  RESPONSIBILITY

     Lessor shall not be held liable to anyone for loss or damage caused in any
     way by the use, leakage or escape of water, or for cessation of any service
     or utility rendered customarily to said premises or buildings or agreed to
     by the terms of this Lease, due to any accident, to the making of repairs,
     alterations or improvements, to labor difficulties, weather conditions, or
     mechanical breakdowns, to trouble or scarcity in obtaining fuel,
     electricity, service or supplies from the

                                     -17-

     sources which they are usually obtained for said building or to any cause
     beyond the Lessor's immediate control.

31.  SURRENDER
     ---------
     Lessee shall at the expiration or earlier termination of this Lease remove
     all of Lessee's goods and effects from the leased premises.  Lessee shall
     deliver to Lessor the leased premises and all keys, locks thereto, and
     other fixtures and equipment connected therewith and all alterations,
     additions and improvements made to or upon the leased premises, including,
     but limited to, any offices, partitions, plumbing and plumbing fixtures,

     order and in the same condition as they were at the commencement of the
     term, or as they were put in during the term hereof, reasonable wear and
     tear and damage by fire or other casualty only excepted.  In the event of
     Lessee's failure to remove any of Lessee's property from the leased
     premises, Lessor is hereby authorized, without liability to Lessee for loss
     or damage thereto, and at the sole risk of Lessee, to remove and store any
     such property at Lessee's expense, or to retain the same under Lessor's
     control, or to sell at public or private sale, without notice, any or all
     of the property not so removed and to apply the net proceeds from such sale
     to the payment of any sum due hereunder, or to destroy such property which
     shall be conclusively deemed to

                                     -18-
<PAGE>
 
     have been abandoned.

32.  WAIVER
     ------
     One or more waivers of any covenant, condition or agreement contained
     herein shall not be construed as a waiver of a further breach of the same
     covenant, condition or agreement or of any other covenant, condition or
     agreement, and a consent or approval by one party to any act by the other
     requiring such consent or approval shall not be deemed a waiver or render
     unnecessary consent or approval to any subsequent similar act.

33.  NO ABATEMENT OF RENT
     --------------------
     The obligation of Lessee to make all payments of rent and any additional
     rent in the form of real estate taxes, operating costs or otherwise shall

     Lease shall be deemed special, unique and extraordinary; and any breach
     thereof by the parties shall be deemed to cause the other party irreparable

     rights and remedies of the parties hereunder may therefore 

                                     -19-
<PAGE>
 
     be enforced both at law and in equity, by injunction or otherwise.
     (C) All rights and remedies of each party shall be cumulative, and not
     alternative, in addition to and not exclusive of any other right or remedy
     to which such party may be lawfully entitled in case of any breach or
     threatened breach of any terms or provisions herein except as otherwise
     expressly provided herein.
     (D) The rights and remedies of each party shall be continuing and not
     exhausted by any one or more uses thereof, and may be exercised at any time
     or from time to time and as often as may be expedient; and any option or
     election to enforce any such right or remedy may be exercised or changed at
     any time or from time to time.
     (E) This Lease sets forth the entire agreement by the parties, and no
     custom, act, forbearance, or words of silence at any time, gratuitous or
     otherwise, shall impose any additional obligation or liability upon either
     party or waive or release either party from any default or from the
     performance or fulfillment of any obligation or liability, or operate as
     against either party as a supplement, alteration, amendment or change of
     any term or provision set forth herein, including this cause, unless set
     forth in a written instrument duly executed by such party expressly stating
     that it is intended to impose such an additional obligation or liability or
     to constitute such a waiver or release, or that it is intended to operate
     as such a supplement, alteration, amendment or change.
     (F) If any term or provision of this Lease or the application thereof to
     any person, property or circumstance shall to any extent be invalid or
     unenforceable, the remaining terms and provision shall not be affected
     thereby, and each term and provision of this Lease shall be valid and

                                     -20-
<PAGE>
 
     enforceable to the fullest extent permitted by Law.

     (H) This Lease shall be construed in accordance with the laws of the STATE
     OF MASSACHUSETTS.

36.  OPTION TO RENEW
     ---------------
     In the event that Lessee is not in default of any of the provisions of this
     Lease at the time of its exercise of the option hereunder and for the

     any such renewal term.  Upon the giving of any such notice, the term of
     this Lease shall automatically be extended for an additional period of
     THREE (3) years(s) without the necessity for the execution of any other
     instrument in confirmation thereof.  Lessor and Lessee shall execute and
     deliver any such instrument in recordable form as either may reasonably
     request for the purpose of confirming this Lease and the exercise of any
     such extension right.  Except for the rights of extension which have
     theretofore been exercised and the rent payable during any such extension
     period, any such extension shall be upon all of the same terms, conditions
     and provisions herein contained.  References in this Lease to the term
     hereof shall be deemed to include any renewal term for which the original
     term may be so extended.  The base rent due and payable by Lessee during
     any such renewal terms shall be in an amount as shall 

                                     -21-

     be mutually agreed upon by Lessor and Lessee prior to the commencement of
     said renewal term.

               $12,000.00/month.
         
          C.   Paragraph 7 is amended to clarify that the base year for
determining the increase in property taxes is City of Haverhill, Massachusetts
fiscal year ending June 30, 1996.

          D.   With respect to Paragraph 8, Lessor hereby acknowledges that
water connections have been and shall be provided by Lessor for domestic
sanitary purposes and for process water usage.  Lessor consents to water usage
by Lessee at the premises up to those levels used by Alternate Circuit
Technology, Inc. during the period of its occupancy of the premises, however.
Any significant increase in water usage over such historical levels will require
Lessor's consent, which consent will not be unreasonably withheld.

          E.   With respect to Paragraph 12 the Lessor agrees that Successor
Lessee shall not have an obligation greater than to restore the premises to its
condition existing prior to the date of the assignment of the Lease by Lessee to
Successor Lessee.

          F.   Paragraph 23 is deleted and the following is substituted in its
place:

               "23.  Signs.  Lessee may place signs on the 
                     -----
               premises with Lessor's written consent which 
               will not be unreasonably withheld.  Lessor 
               hereby consents to Lessee placing a new sign 
               on the premises in substantially the same size 
               as the current sign.

          H.   Paragraph 29 of the Lease is clarified as follows:

               "Hazardous materials have been and may in the 
               future be used by Lessee in connection with 
               the manufacturing processes conducted by Lessee 
               at the leased premises provided such use complies 
               with applicable federal and state laws.  No 
               hazardous waste or chemical waste may be 
               permanently stored on the leased premises.
               For purposes of this paragraph "permanently 
               stored" shall mean storage for more than 
               ninety (90) days from the first day of such storage."

          I.   Paragraph 31 of the Lease is clarified to provide that Successor
Lessee shall deliver the leased premises in a clean and neat order and in the
same condition as they were on the date of the assignment of the Lease by Lessee
to Successor Lessee.

          J.   Paragraph 36 of the Lease is amended to provide that Successor
Lessee shall have an option to renew the lease for one additional five-year term
on the expiration of the term of this Lease as set forth in paragraph 2, 
provided, however, that in no event 

                                       4
<PAGE>
 
shall the rental for such extended term be less than the rental in
effect at the end of the prior term.  Such rights shall be subject to the
procedures and conditions set forth in paragraph 36 of the existing Lease.

          K.   Paragraph 37 of the Lease is amended to read in full as follows:

               "37.  Rules and Regulations.  Lessee agrees
                     --------------------- 
               to comply with the rules and regulations set 
               forth in the Exhibit attached to this Lease 
               (as the same may be reasonably amended from 
               time to time) as to the use and/or occupancy 
               of the leased premises and land and buildings 
               of which the same form a part, and the same 
               are incorporated by reference herein and made 
               a part of this Lease."

     5.    Acknowledgment of Storage Tanks and Lessor's Responsibility.  Lessor
           -----------------------------------------------------------         
hereby acknowledges that another tenant has two (2) storage tanks located on the
leased premises. Lessor agrees to perform and/or cause such other tenant to
perform all necessary repairs, maintenance, and replacements of said storage
tanks during the term of the Lease, at Lessor's or such other tenant's sole cost
and expense. Lessor further agrees to maintain and/or cause such other tenant to
maintain the storage tanks in compliance with all applicable federal, state or
local environmental laws or ordinances applicable to or governing storage tanks.

     6.   Indemnity and Hold Harmless by Lessor.  Lessor shall indemnify
          -------------------------------------                         
Successor Lessee and hold Successor Lessee harmless from and against any and all
claims, losses, expenses or costs of any nature, including attorneys' fees and
expert witness fees, which 

                                       5
<PAGE>
 
result, or which arise in any manner from the presence of said two (2) 
storage tanks located on the leased premises. It is understood that Successor
Lessee would not enter into this Consent to Assignment, Certification and Lease
Amendment in the absence of Lessor's agreement to indemnify and hold harmless,
as herein described. It is recognized and agreed that such agreement to
indemnify and hold harmless includes, without limiting the generality of such
provision, all expenses and costs, including attorneys' fees and expert witness
fees, which result from any administrative inquiry by any governmental agency.

     7.   Successor Lessee consents to Lessor transferring its interest in the
Lease to a limited liability company owned by the current beneficial owners of
Lessor.

          ------

          Employee is engaged as                 of Employer and shall perform
                                 ---------------

     10.  Customers of Business
          ---------------------
                                                  
          A.   Employee acknowledges that his employment by Employer will bring
him into close contact with many confidential affairs of Employer, including
information about costs, profits, markets, sales, key personnel, pricing
policies, operational methods and other business affairs, methods and
information, including plans for future developments, not readily available to
the public. Employee further acknowledges that the services to be performed
under this Agreement are of a special, unique, unusual, extraordinary and
intellectual character; that the business of the company is national in scope,
that its services are marketed throughout the United States, and Employer
competes with other organizations that are or could be located in nearly any
part of the Untied States,. In recognition of the foregoing, Employee covenants
and agrees that:

                                       2
<PAGE>
 
               i.   He will not knowingly divulge any material confidential 
matters with respect to Employer which are not otherwise in the public domain 
and will not intentionally disclose them to anyone outside of Employer during 
his  employment by Employer hereunder or following the expiration or 
termination of his employment with Employer for any reason.

               ii.  He will deliver promptly to Employer at the end of the 
Term, or at any other time Employer may so request, all memoranda, notes, 
records, reports and other documents (and all copies thereof) relating to the 
businesses of Employer and which he may then possess or have under this control;

               iii. During the Term and any additional period during which 
Employee may be employed by Employer (whether or not such employment shall be
pursuant to written agreement) Employee will not, unless the Board shall
otherwise consent, alone or together with any other person, firm, partnership,
corporation or other entity whatsoever (except any subsidiaries or affiliates of
Employer), directly or indirectly, whether as an officer, director, shareholder,
partner, proprietor, associate, employee, representative, management consultant
or otherwise engage in, or become or be interest in or associated with any other
person, corporation, firm, partnership or other entity whatsoever engaged in,
any business which is competitive with any business conducted by Employer.

          B.   Employee agrees that the remedy at law for any breach or
threatened breach of any covenant contained in this Section 10 will be
inadequate and that Employer, in addition to such other remedies as may be
available to it, in law or in equity, shall be entitled to injunctive relief
without bond or other security.

     11.  Termination
          -----------

          This agreement may be terminated:

          A.   Death.  In the event of the death of Employee during the Term,
               -----                                                         
employment hereunder shall terminate on the date of Employee's death.

          B.   Disability.  If, because of illness, physical or mental 
               ----------
disability or other incapacity Employee shall fail for a continuous period of 
three months or periods aggregating six months in any twelve month period, to 
render the services provided for in this agreement, then either party may 
terminate this agreement.

          C.   Cause.  Employer may terminate Employee at any time for cause in
               -----                                                           
which event Employer has no further obligation to pay any compensation to
Employee.  For purposes of this agreement 

                                       3

misconduct.

               iii. Gross failure to execute those duties reasonably assigned 
to Employee by Employer within ten days after written notice of such failure.

which were previously the subject of a written notice shall constitute "cause"
without the necessity of a second notice.

               iv.  Conviction of or guilty plea to any felony or crime of 
moral turpitude.

          D.  Without Cause.  If Employee is terminated by Employer for any
              -------------                                                
reason other than death, disability or cause, Employer shall pay to Employee the
base salary (as set forth in Section 3(a)) and employee fringe benefits (as set
forth in Section 5) for the remainder of the term of the Agreement (payable
monthly), but Employee shall not be entitled to any performance incentive
compensation.

     12.  Termination of Agreement
          ------------------------

          Subject to Employer's obligations under Paragraph 5 above, this
agreement shall be terminated by the death of Employee, by mutual agreement of
the parties, or by either party giving the other not less than ninety (90) days'
written notice of termination, and all rights of the parties hereto, for the
last year of employment, or for any part thereof, pursuant to this agreement,
shall survive any such termination.

                               ESCROW AGREEMENT

     This Escrow Agreement (the "Escrow Agreement") is made and entered into as
of this 10th day of June 1996 by and among Zycon Corporation, a Delaware
corporation ("Company A"), Alternate Circuit Technology, Inc., a Massachusetts
corporation ("Company B"), and State Street Bank and Trust Company, a
Massachusetts trust company, as escrow agent (the "Escrow Agent").

     WHEREAS, Company A and Company B have executed an Asset Purchase Agreement
(the "Agreement") dated June 7, 1996 pursuant to which Company A has agreed to
deposit $1,000,000.00 in an escrow account with the Escrow Agent pursuant to the
terms of this Escrow Agreement; and

     WHEREAS, State Street Bank and Trust Company is willing to serve as Escrow
Agent pursuant to the terms and conditions hereinafter set forth.

     NOW, THEREFORE, in consideration of the promises and agreements contained
herein, and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged by each party hereto, it is hereby agreed by
and among Company A, Company B and the Escrow Agent as follows:

     1.  Escrow Amount.  On the date hereof, Company A has delivered to the
Escrow Agent funds in aggregate amount of $250,000.  By June 18, 1996, or such
later date as Company A and Company B mutually agree, Company A will deliver to
the Escrow Agent additional funds in the aggregate amount of $750,000.  The sum
of the $250,000 and $750,000 (or such lesser amount as permitted by Section 2.2
of the Agreement) deposits (together with any interest that may accrue thereon
from and after the date thereof) shall be referred to as the "Escrow Funds."
The Escrow Agent shall not be required to inquire into the propriety of the
Escrow Funds deposited hereunder nor shall the Escrow Agent be required to
investigate any other matter or arrangement between Company A and Company B.

     2.  Disbursement of Escrow Funds.  The Escrow Agent shall release all or a
portion of the Escrow Funds only upon receipt by the Escrow Agent of a letter
(the "Escrow Release Letter") executed by each of Company A and Company B and
then only in the amount and in accordance with the instructions contained in the
Escrow Release Letter.  Except as provided in this Section 2 or in Section 12
hereof or as otherwise agreed upon in writing by Company A and Company B, the
Escrow Agent shall not release all or any portion of the Escrow Funds.

     3.  Investment of Escrow Funds. The Escrow Agent shall invest the Escrow
Funds as directed in writing by Company A in federal funds, certificates of
deposit, or interest bearing accounts with any U.S. bank or trust company,
including the Escrow Agent, incorporated under the laws of the United States or
any state thereof, and either (a) having capital
<PAGE>
 
and surplus in excess of $50,000,000, or (b) whose unsecured short term debt
obligations (or, in the case of a bank or trust company in a bank holding
company system, debt obligations of the bank holding company) at the date of
acquisition thereof have a rating of not less than "A-1" from Standard & Poor's,
a division of The McGraw-Hill Companies, Inc. ("S&P"), and "P-1" by Moody's
Investors Service, Inc. ("Moody's");

     4.  Duties and Responsibilities of Escrow Agent.
 
         (a)  Company A and Company B acknowledge and agree that the Escrow 
Agent (i) shall not be responsible for any of the agreements referred to herein
but shall be obligated only for the performance of such duties as are
specifically set forth in this Escrow Agreement; (ii) shall not be obligated to
take any legal or other action hereunder which might in its judgment involve any
expense or liability unless it shall have been furnished with acceptable
indemnification; (iii) may rely on and shall be protected in acting or
refraining from acting upon any written notice, instruction, instrument,
statement, request or document furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper person, and shall
have no responsibility for determining the accuracy thereof, and (iv) may
consult counsel satisfactory to it, including house counsel, and the opinion of
such counsel shall be full and complete authorization and protection in respect
of any action taken, suffered or omitted by it hereunder in good faith and in
accordance with the opinion of such counsel.

         (b)  Neither the Escrow Agent nor any of its directors, officers or
employees shall be liable to anyone for any action taken or omitted to be taken
by it or any of its directors, officers or employees hereunder except in the
case of gross negligence or willful misconduct. Nor shall the Escrow Agent be
liable for any loss arising from the making or retention of any investment in
accordance with this Escrow Agreement. Company A and Company B, jointly and
severally, covenant and agree to indemnify the Escrow Agent and hold it harmless
without limitation from and against any loss, liability or expense of any nature
incurred by the Escrow Agent arising out of or in connection with this Escrow
Agreement or with the administration of its duties hereunder, including but not
limited to legal fees and other costs and expenses of defending or preparing to
defend against any claim or liability in the premises, unless such loss,
liability or expense shall be caused by the Escrow Agent's willful misconduct or
gross negligence.  In no event shall the Escrow Agent be liable for indirect,
punitive, special or consequential damages.

         (c)  Company A and Company B, jointly and severally, agree to assume 
any and all obligations imposed now or hereafter by any applicable tax law with
respect to the payment of Escrow Funds under this Escrow 

                                       2
<PAGE>
 
Agreement, and to indemnify and hold the Escrow Agent harmless from and against
any taxes, additions for late payment, interest, penalties and other expenses,
that may be assessed against the Escrow Agent on any such payment or other
activities under this Escrow Agreement.  Company A and Company B undertake to
instruct the Escrow Agent in writing with respect to the Escrow Agent's
responsibility for withholding and other taxes, assessments or other
governmental charges, certifications and governmental reporting in connection
with its acting as Escrow Agent under this Escrow Agreement.  Company A and
Company B, jointly and severally, agree to indemnify and hold the Escrow Agent
harmless from any liability on account of taxes, assessments or other
governmental charges, including without limitation the withholding or deduction
or the failure to withhold or deduct same, and any liability for failure to
obtain proper certifications or to properly report to governmental authorities,
to which the Escrow Agent may be or become subject in connection with or which
arises out of this Escrow Agreement, including costs and expenses (including
reasonable legal fees), interest and penalties.

         (d)  The Escrow Agent shall have no more or less responsibility or
liability on account of any action or omission of any book-entry depository or
subescrow agent employed by the Escrow Agent than any such book-entry depository
or subescrow agent has to the Escrow Agent, except to the extent that such
action or omission of any book-entry depository or subescrow agent was caused by
the Escrow Agent's own negligence or bad faith.

         (e)  Company A and Company B jointly and severally agree to pay the 
fees of, and to reimburse all expenses (including the reasonable fees and
expenses of counsel) incurred by, the Escrow Agent in entering into this Escrow
Agreement and performing its duties and responsibilities hereunder, including
the Escrow Agent's reasonable compensation for its normal services hereunder in
accordance with the attached fee schedule. The Escrow Agent shall be entitled to
reimbursement on demand for all expenses incurred in connection with the
administration of the escrow created hereby which are in excess of its
compensation for normal services here under, including without limitation,
payment of any legal fees incurred by the Escrow Agent in connection with
resolution of any claim by any party hereunder. If any such fees or expenses
remain unpaid at the time the Escrow Agent has been directed to release the
Escrow Funds pursuant to Section 2 or Section 12 hereof, it may deduct such
unpaid fees and expenses prior to such release.

         (f)  The Escrow Agent may at any time resign as Escrow Agent hereunder 
by giving thirty (30) days' prior written notice of resignation to Company A and
Company B. Prior to the effective date of the resignation as specified in such
notice, Company A will issue to the Escrow Agent a written instruction
authorizing redelivery of the Escrow Funds to a bank or trust company that it
selects subject to the reasonable consent of Company B.  Such bank or trust
company shall have a principal office in Boston, 

                                       3
<PAGE>
 
Massachusetts, shall have capital, surplus and undivided profits in excess of
$50,000,000, and shall have agreed to act as Escrow Agent hereunder and upon
such additional terms and conditions as it and Company A and/or Company B shall
have agreed, if any, provided that the original Escrow Agent shall have no
responsibility therefor nor any responsibility for the compensation of such
successor Escrow Agent.  If, however, Company A shall fail to name such a
successor escrow agent within twenty (20) days after the notice of resignation
from the Escrow Agent, then Company B shall be entitled to name such successor
escrow agent.  If no successor escrow agent is named by either Company A or
Company B pursuant to the foregoing provisions by the effective date of the
Escrow Agent's resignation, then the Escrow Agent shall deliver the Escrow Funds
to Company A, whereupon all obligations of the Escrow Agent shall be deemed
fulfilled, and the Escrow Agreement shall terminate, provided that the
provisions of paragraph (b) and (c) shall survive the termination of this Escrow
Agreement.

         (g)  This Escrow Agreement sets forth exclusively the duties of the 
Escrow Agent with respect to any and all matters pertinent thereto and no
implied duties or obligations shall be read into this Escrow Agreement against
the Escrow Agent.

     5.  Dispute Resolution.  It is understood and agreed that should any
dispute arise with respect to the delivery, ownership, right of possession,
and/or disposition of the Escrow Funds, or should any claim be made upon such
Escrow Fund by a third party, the Escrow Agent upon receipt of written notice of
such dispute or claim by the parties hereto or by a third party, is authorized
and directed to retain in its possession without liability to anyone, all or any
of the Escrow Funds until such dispute shall have been settled either by the
mutual agreement of the parties involved or by a final order, decree or judgment
of a Court in the United States of America, the time for perfection of an appeal
of such order, decree or judgment having expired.  The Escrow Agent may, but
shall be under no duty whatsoever to, institute or defend any legal proceedings
which relate to the Escrow Funds.  The Escrow Agent shall have the right to
retain counsel of its choice in case it becomes involved in any disagreement,
dispute or litigation related to the Escrow Agreement or the Escrow Funds, or
otherwise determines that it is necessary or desirable to consult counsel, and
the reasonable fees and expenses of such counsel shall be reimbursed to the
Escrow Agent as provided in Section 4 hereof.

     6.  Consent to Jurisdiction and Service.  Company A and Company B hereby
absolutely and irrevocably consent and submit to the jurisdiction of the courts
of the Commonwealth of Massachusetts and of any Federal court located in said
Commonwealth in connection with any actions or proceedings brought against
either or both of them by the Escrow Agent arising out of or relating to this
Escrow Agreement.  In any such action or proceeding, Company A and Company 

                                       4

B hereby absolutely and irrevocably waive personal service of any summons,
complaint, declaration or other process and hereby absolutely and irrevocably
agree that the service thereof may be made by certified or registered first-
class mail directed to Company A or Company B, as the case may be, at their
respective addresses in accordance with Section 8 hereof.

     7.  Force Majeure.  Neither Company A nor Company B nor the Escrow Agent
shall be responsible for delays or failures in performance resulting from acts
beyond its control. Such acts shall include but not be limited to acts of God,
strikes, lockouts, riots, acts of war, epidemics, governmental regulations
superimposed after the fact, fire, communication line failures, power failures,
