ITEM 2.     ACQUISITION OR DISPOSITION OF ASSETS.

            In May of 1995, the board of directors of GTI Corporation, a
Delaware corporation (the "Company"), adopted a formal plan to sell its non-core
business units as part of the Company's strategic focus on the networking and
network access markets. At that time, the Company's non-core business units
consisted of its electronic components and equipment segment and its
distribution products segment.

            Historically, these two business units have been reported as
separate business segments. The two segments each have separate and identifiable
assets, results of operations, and activities that are clearly distinguishable
from each other as well as from the Company's other assets and operations. In
connection with its decision to sell its non-core business units, the Company
began accounting for the electronic components and equipment segment and
distribution products segment as discontinued operations in accordance with
Accounting Principles Board Opinion No. 30.

            As reported in the Company's previously filed form 10-Q for the
quarterly period ended September 30, 1995, during September and October the
Company entered into separate letters of intent to sell the assets of the
electronic components and equipment segment and the stock of the distribution
products segment.

            SALE OF ELECTRONIC COMPONENTS AND EQUIPMENT SEGMENT

            The Company; Component Intertechnologies, Inc., a Delaware
corporation, (the "Buyer"); and the Buyer's wholly-owned subsidiary,
Component-Ireland Holding Corporation, a Delaware corporation (the "Buyer's
Subsidiary"), entered into an asset purchase agreement dated as of December 16,
1995 (the "Agreement"). Pursuant to the Agreement, on December 21, 1995, the
Company sold substantially all of the assets of its electronic components
segment and certain related assets (together the "Division") as a going concern
to the Buyer and to the Buyer's Subsidiary in exchange for $12,500,000 (subject
to certain adjustments) and the assumption of certain liabilities. The Company
determined the amount of consideration for which it was willing to sell the
Division based on an initial estimation by management of the value of the
Division and on the response of various potential purchasers to the estimated
asking price. The Buyer is unrelated to the Company, its affiliates, directors,
officers, and associates of its directors and officers.

            BUSINESS OF THE DIVISION

            The Division develops, manufactures, markets, and sells glass
components, welded leads, glass-to-metal seals, welded resistor elements, pins,
and pinned arrays for the glass diode, resistor, automotive, and component
packaging markets and application-specific printed circuit boards for automotive
and electrical lighting manufacturers. The Division includes manufacturing
facilities in Hadley, Pennsylvania, and Hartselle, Alabama, and 24,999 shares
representing 100% of GTI-Ireland Limited which operates the Division's
manufacturing facility in Abbeyfeale, Republic of Ireland.

            TERMS OF THE DISPOSITION

            The Buyer paid for the Division with cash in the amount of
$11,750,000, a $250,000 payment to an escrow account (subject to the terms of an
escrow agreement), and a promissory note in the principal amount of $500,000
maturing in three years at the latest and bearing interest at the rate of 8% per
annum.

            In the Agreement, the Company undertook not to compete with the
Buyer in the businesses of the Division in the places where the Division does
business or has been doing business in the past five years. The Company also
indemnified the Buyer for losses arising out of any breaches of the Agreement or
certain related documents. Under certain circumstances, the Buyer has recourse
against the amount held in escrow to recover any losses for which the Buyer is
indemnified. The maximum claim under the indemnity in favor of the Buyer is
$12,500,000.

            SALE OF DISTRIBUTION PRODUCTS SEGMENT

            The Company; Insulectro, a California corporation (the "Buyer"); and
the Buyer's wholly-owned subsidiary, QI Electronics, a California corporation
(the "Buyer's Subsidiary"), entered into a stock purchase agreement dated as of
February 15, 1996 (the "Agreement"). Pursuant to the Agreement, on February 16,
1996 (the "Closing Date"), the Company sold all the issued and outstanding
shares of stock of the legal entities which operates the distribution products
segment. In exchange for 100% of the capital stock of ESCO Sales, Inc., a
Delaware corporation ("ESCO") and the 20% of the capital stock held by the
Company of ESCO's 80%-owned subsidiary, Electronic Supply Corporation, Inc., a
Delaware corporation (the "Subsidiary"), the Buyers and the Buyer's Subsidiary
agreed to pay an amount equal to the tangible net book value of ESCO on the
Closing Date. For purposes of determining the amount of consideration to be paid
on the Closing Date, the tangible net book value was estimated to be $4,118,000
(subject to certain adjustments).

            The Buyer is unrelated to the Company, its affiliates, directors,
officers, and associates of its directors and officers.

            BUSINESS OF THE SUBSIDIARY

            The Subsidiary is a stocking distributor of interconnect, passive
and electromechanical components used in the medical instrumentation, power
supply, computer and computer peripheral, communications, controls, and
industrial equipment industries. The Subsidiary also provides value-added
capabilities in the manufacturing of cable assemblies. The Subsidiary serves
original equipment manufacturers located in the Western United Sates through its
principal administrative, marketing and distribution facility located in
Ontario, California, as well as through satellite sales offices located in San
Jose, California; San Diego, California; Tempe, Arizona; and Denver, Colorado.

            TERMS OF THE DISPOSITION

            The Buyer paid for the stock of ESCO and the Subsidiary with cash in
the amount of $2,118,000, (subject to dollar-for-dollar adjustment based on the
difference between the final tangible net-book value and the estimated tangible
net-book value at the Closing Date), and a subordinated promissory note in the
principal amount of $1,900,000 maturing in six years, bearing interest at a rate
of six percent per annum, principal and interest payable semi-annually,
commencing August 1996 and ending February 2002. The promissory note is
subordinated in accordance with the terms of a subordination agreement.

            In the Agreement, the Company agreed that, for a period of five
years from the Closing, in the event that the Company acquires, directly or
indirectly, a business that, in whole or in part, competes with the business of
the Subsidiary, then the Company shall have one year to dispose of such
competing business. The Company shall allow the Buyer the first offer to acquire
such business and if such offer is rejected, the Company will not sell or
transfer such business to a third party on materially more favorable terms to
such third party. The Company also indemnified the Buyer for losses arising out
of any breaches of the Agreement and certain related documents. The Buyer shall
be entitled to set-off against any amount due or payable to the Company under
the promissory note the amount of losses for which the Buyer is indemnified. The
maximum claim under the indemnity in favor of the Buyer is $4,118,000.

       NOTES TO THE PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION
                             (dollars in thousands)

Note 1      Pro Forma Adjustments:

The accompanying pro forma financial statements are presented in accordance with
Article 11 of Regulations S-X.

The unaudited, pro forma, consolidated balance sheet has been prepared as if the
disposal of the E-Group and ESCO were completed as of January 1, 1995.

The unaudited, pro forma, consolidated statements of operations for the year
ended December 31, 1994, and the nine months ended September 30, 1995, were
prepared as if the disposal of the E-Group and ESCO were completed as of
January 1, 1994, and January 1, 1995, respectively. The unaudited, pro forma,
consolidated statements of operations were prepared based upon historical
financial information from the consolidated GTI Corporation, the E-Group, and
ESCO financial statements for the periods indicated above.

The unaudited, pro forma financial information should be read in conjunction
with the historical, consolidated financial statements of GTI Corporation, as
previously filed.

The unaudited, pro forma financial information does not include an adjustment to
reduce or eliminate the Company's secondary public offering of 650,000 shares of
common stock in January 1995 in connection with the Company's acquisition of
approximately 71% of Promptus Communications, Inc. ("Promptus"). The proceeds
from the secondary public offering are assumed to be used to complete the
Promptus acquisition and for general corporate purposes. The unaudited, pro
forma statement of operations for the year ended December 31, 1994, includes an
adjustment related to the interest that could have been earned on the disposal
proceeds. Additionally, the unaudited pro forma statement of operations for the
nine months ended September 30, 1995, includes an adjustment for a reduction in
the interest costs associated with the acquisition of Promptus.

The following pro forma adjustments have been made to the pro forma,
consolidated financial statements:

(A) - Represents the cash proceeds from the disposal of the E-Group.

                            STOCK PURCHASE AGREEMENT

         This Stock Purchase Agreement (this "Agreement"), dated as of February
15, 1996, is made by and among QI Electronics ("QI"), a California corporation,
Insulectro, a California corporation, GTI Corporation, a Delaware corporation
("GTI"), Esco Sales, Inc., a Delaware corporation ("Holdings") and Electronic
Supply Corporation, a Delaware corporation ("ESCO").

                                    RECITALS

         A.   QI Electronics is a wholly owned subsidiary of Insulectro.
Insulectro and QI are referred to hereafter, individually and collectively, as
the "Buyers".

         B.   ESCO is eighty percent owned by Holdings and twenty percent owned
by GTI. Holdings is a wholly owned subsidiary of GTI. ESCO, Holdings and GTI are
referred to hereafter, individually and collectively, as the "Sellers".

         C.   ESCO is engaged in the business of distributing electronic
components (the "Business"). Holdings is a holding company and is not engaged in
any business except that of holding the stock of ESCO.

         D.   QI desires to purchase from GTI and GTI desires to sell to QI all
of the issued and outstanding shares of stock of Holdings and all of the ESCO
stock held by GTI (the "Shares"), pursuant to the terms and conditions set forth
in this Agreement.


                                    AGREEMENT

          In consideration of the mutual covenants, representations, warranties
and agreements set forth in this Agreement, the parties hereto agree as follows:

1.       PURCHASE AND SALE OF STOCK.

         1.1. Acquisition of Shares. Subject to the terms and conditions set
forth in this Agreement, on the Closing Date (as defined in Article 2,) the
Buyers hereby agree to purchase, and the Sellers hereby agree to sell all of the
issued and outstanding stock of Holdings and all of the stock of ESCO held by
GTI.

         1.2. Purchase Price.

                  1.2.1. As consideration for the Shares, the Buyers agree to
pay to GTI an amount equal to the Tangible Net Book Value of Holdings as of the
close of business on the Closing Date (the "Purchase Price"). For this purpose,
"Tangible Net Book Value" means the excess of the consolidated assets of
Holdings and ESCO, but not including (i) goodwill or going concern value, (ii)
cash, or (iii) intercompany accounts, over the consolidated liabilities of
Holdings and ESCO, as adjusted and calculated in accordance with the procedure
established for determining the Closing Balance Sheet in Exhibit C. Tangible Net
Book Value shall be determined by using US generally accepted accounting
principles in a manner consistent with those used in preparing the audited
balance sheet of ESCO as of December 31, 1995 described in Section 6.12 (the
"Accounting Principles"), provided, however, that in determining the Tangible
Net Book Value, the reserve against the accounts receivable shall be $171,000
and the reserve against inventory shall be $156,000.


                                       1
<PAGE>   2
                  1.2.2. For purposes of determining the amount of cash to be
paid at the Closing, the Tangible Net Book Value is hereby estimated to be
$4,118,000 (the "Estimated TNBV").

                  1.2.3. If the Tangible Net Book Value at the close of business
on the Closing Date is less than the Estimated TNBV, then the Purchase Price
shall be reduced dollar-for-dollar by the amount of such deficiency. If the
Tangible Net Book Value at the close of business on the Closing Date is greater
than the Estimated TNBV, then the Purchase Price shall be increased
dollar-for-dollar by the amount of such excess. Such difference is referred to
herein as the "Post-Closing Purchase Price Adjustment".

                  1.2.4. Within five business days after the determination of
the Post-Closing Purchase Price Adjustment is made, Insulectro or GTI, as the
case may be, shall deliver the Post-Closing Purchase Price Adjustment by wire
transfer of federal funds, together with interest on such amount from the
Closing Date until paid at a rate equal to 5% per annum.

         1.3.  Payment Terms. The Purchase Price shall be paid as follows:

                  (i) The first one million nine hundred thousand dollars
($1,900,000) of the Purchase Price shall be paid in the form of a six (6) year,
one million nine hundred thousand dollar ($1,900,000) subordinated promissory
note issued by Insulectro in the form attached hereto as Exhibit A (the
"Promissory Note") bearing interest at rate of six percent (6%) per annum,
principal and interest payable semi-annually. The Promissory Note shall be
subordinated in accordance with the terms of the subordination agreement
attached hereto as Exhibit B (the "Subordination Agreement").

         In the event of an event of default (as defined in the Note) and if GTI
is successful in reducing the Note to a judgment against Insulectro, then the
amount of such judgment shall bear prejudgment interest at the rate of 10% per
annum from the date of the event of default provided that GTI has delivered to
Insulectro within 45 days of the Close, a copy of the policy or the policy
number and a general description thereof, e.g. "general liability" of each
liability insurance policy held by or for the benefit of ESCO, or any
predecessor in interest, since incorporation (the "Insurance Information"). In
the event that GTI fails to provide the Insurance Information during the
required period then there shall be no prejudgment increase in the stated 6%
interest rate payable under the Note in the event of an event of default.

                  (ii)     The sum of $2,218,000 shall be paid by Buyers to GTI 
on the Closing Date by wire transfer as follows:

         1.4      Closing Balance Sheet.

                  1.4.1. Preliminary and Adjusted Closing Balance Sheets.
Promptly after the Closing, GTI, (with such assistance as GTI shall reasonably
request of the Buyers and the other Sellers) shall prepare a consolidated
balance sheet of Holdings and ESCO as of the close of business on the Closing
Date (the "Preliminary Closing Balance Sheet"). The Preliminary Closing Balance
Sheet shall be prepared in accordance with the Accounting Principles. ESCO
conducted a physical inventory count on December 15, 1995 and such count, as
rolled forward to reflect transactions prior to the Closing, will be used as the
inventory count. GTI shall engage Arthur Andersen & Co., LLP, at its sole
expense, to perform the procedures described on Exhibit C hereto with respect to
the Preliminary Closing Balance Sheet and to deliver a report to the Buyers and
GTI of their findings. Based upon such report, GTI shall make such adjustments,
if any, to the Preliminary Closing Balance Sheet as shall be required to cause
the Preliminary Closing Balance Sheet to reflect fairly the adjustments
described in the report in accordance with the Accounting Principles and shall
deliver such revised balance sheet to the Buyers (the "Adjusted Closing Balance
Sheet").

                  1.4.2. Delivery of Adjusted Closing Balance Sheet. As soon as
practicable following the Closing, but in no event later than April 1, 1996, the
Adjusted Closing Balance Sheet shall be delivered by GTI to the Buyers. The
Buyers and their representatives shall be provided complete access to all work
papers and other information used by GTI in preparing the Adjusted Closing
Balance Sheet. The Adjusted Closing Balance Sheet, when delivered by GTI to the
Buyers, shall be deemed conclusive and binding on the parties for purposes of
determining the Post-Closing Purchase Price Adjustment, unless the Buyers notify
GTI in writing within 30 days after receipt of the Adjusted Closing Balance
Sheet of their disagreement therewith, which notice shall state with reasonable
specificity the reasons for any disagreement and identify the items and amounts
in dispute.

                  1.4.3. Arbitration. If any disagreement concerning the
Post-Closing Purchase Price Adjustment is not resolved by the Buyers and GTI
within 30 days following delivery by the Buyers of its notice or objection to
the Adjusted Closing Balance Sheet, the undisputed amount shall be paid in
accordance with Section 1.2, and the Buyers and GTI shall promptly engage on
standard terms and conditions for a matter of such nature a nationally
recognized firm of independent accountants to resolve such dispute. The firm of
independent accountants shall be proposed in writing by the Buyers to GTI. In
the absence of agreement on the identity of the independent accountants within
five (5) business days, the Orange County, California office of the accounting
firm of Price Waterhouse LLP shall be engaged by the parties. The engagement
agreement with the independent accountants shall require the independent
accountants to make their determination with respect to the items in dispute
within 90 days following the delivery by the Buyers of their notice of objection
to the Adjusted Closing Balance Sheet. The Buyers and GTI shall each pay
one-half of the cost of the fees and expenses of such independent accountants at
the time of payment of the Post-Closing Purchase Price Adjustment. The
resolution by the independent accountants of any dispute concerning the
Post-Closing Purchase Price Adjustment shall be final, binding and conclusive
upon the parties and shall be the parties' sole and exclusive remedy regarding
any dispute concerning the Post-Closing Purchase Price Adjustment.

                  1.4.4. Final Closing Balance Sheet. The Adjusted Closing
Balance Sheet, as modified by the parties' agreement and by any determination by
the independent accountants as described in this Section 1.4, shall be the
"Closing Balance Sheet".

ability to compete with the Buyers in the future.

                  5.10.1. In the event, for a period of five (5) years from the
Close, GTI acquires, directly or indirectly, a business that, in whole or in
part, competes with ESCO's existing business, then GTI shall have one (1) year

first offer to acquire such business and if such offer is rejected, GTI will not
sell or transfer such business to a third party on materially more favorable
terms to such third party. Insulectro will have one month from the date GTI
notifies it in writing of the acquisition to make the offer.

                  5.10.4. GTI acknowledges that (1) the covenants and the
restrictions contained in this section 5.10 are necessary, fundamental, and
required for the protection of the goodwill of the Business; (2) such covenants
relate to matters which are of a special, unique and extraordinary character
that gives each of such covenants a special, unique and extraordinary value; and
(3) a breach of such covenants or any other provision of this Section 5.10 will
result in irreparable harm and damages to the affected party which cannot be
adequately compensated by a monetary award. Accordingly, it is expressly agreed
that in addition to all other remedies available at law or in equity, the Buyers
shall be entitled to the immediate remedy of a temporary restraining order,
preliminary injunction, or such other form of injunctive or equitable relief as
may be used by any court of competent jurisdiction to restrain or enjoin any of
the parties hereto from breaching any such covenant or provision or to
specifically enforce the provisions hereof.

                  5.10.5. In the event that any provision of this Section 5.10
is more restrictive than permitted by the law of the jurisdiction in which the
Buyers seek enforcement thereof, the provisions of this Section 5.10 shall be
limited only to the extent that a judicial determination finds the same to be
unreasonable or otherwise unenforceable. Such invalidity or unenforceability
shall not affect any other terms herein, but such terms shall be deemed deleted,
and such deletion shall not affect the validity of the other terms hereof. In
addition, if any one or more of the terms contained in this section 5.10 shall
for any reason be held to be excessively broad, or of an overly long duration,
that term shall be construed in a manner to enable it to be enforced to the
extent compatible with applicable law. Moreover, notwithstanding any judicial
determination that any provision of this section 5.10 is not specifically
enforceable, the parties intend that the Buyers shall nonetheless be entitled to
recover monetary damages as a result of any breach hereof.

         5.11. VALOR Distribution Agreement. Contemporaneously with the Close,
GTI shall cause it subsidiary Valor Electronics, Inc. ("Valor") to amend the
existing distribution agreement extending the term thereof for five years and

employee who became entitled to such COBRA rights prior to the Closing

The income of ESCO and Holdings shall be apportioned for the period up to and

Closing Date. All tax sharing arrangements between GTI and Holdings or ESCO
shall be terminated as of the close of business on the day of the Close, and

and all federal and state income taxes for the period ending on the close of

other, and the Buyers shall cause Holdings and ESCO to provide to GTI, with such
assistance as may reasonably be requested by any of them in connection with the
preparation of any financial statement or tax return, tax audit, or any judicial
or administrative proceedings relating to any financial statements or tax
returns, and each will retain and provide the other with any records or
information that may be relevant to such items. The party requesting assistance

shall reimburse and pay to Insulectro at the Close the sum of $7,975 to
reimburse Insulectro for a portion of the attorney's fees and costs incurred by
Insulectro in connection with the preparation and distribution of this
Agreement, including all prior drafts of this Agreement, resulting from changes
by GTI to the transaction contemplated by this Agreement.

         5.16. Insurance Policies. The Sellers shall use their best efforts to
locate and deliver to the Buyers, following the Close, a copy of each liability
insurance policy held by or for the benefit of ESCO, or any predecessor in
interest, since incorporation or a policy number and a general description, e.g.
"general liability", of each such policy (the" Insurance Information"). After
the close, GTI shall continue to use its best efforts to deliver to Insulectro
all of the Insurance Information within 45 days of the Close not delivered prior
to the Close. In the event GTI fails to deliver all of the Insurance Information
to Insulectro within 45 days of the Close, Insulectro shall have the right, at
GTI's expense, to retain an advisor of its choice to locate or recreate such
missing Insurance Information.

         5.17 Obligations Regarding Write offs. The parties acknowledge that
Sellers have written off approximately nine hundred ten thousand dollars
($910,000) on ESCO's financial statements as described Section 6.12.2 hereof,
and that the purchase price discussed between the parties earlier has been
reduced as a result of such write off. Buyers, Holdings and ESCO agree to
provide such cooperation as GTI may reasonably request in order to investigate
further the cause of such write off and to pursue any recovery from insurers,
employees, or other third parties provided that ESCO shall have the right to
decline to have a lawsuit filed in its name if such would expose ESCO to
unreasonable litigation risks. In the event any portion of such write off is
recovered and received by any party other than GTI, such party shall pay such
amount to GTI. In no event shall ESCO, Holdings and Buyers be liable to GTI for
any portion of such writeoff except to the extent of funds actually received by
them. GTI agrees to reimburse ESCO, Holdings and Buyers for any reasonable out
of pocket expenses, including reasonable compensation for time devoted to the
matter by ESCO employees they may incur and to indemnify them against any loss,
damage, cost or expense they may incur in connection with the matters described

receive an amount sufficient to reimburse expenses incurred by ESCO in
connection with such matters.

         5.18 Leases. GTI is a guarantor on certain leases for the benefit of
ESCO. The parties agree to take such actions as may be reasonable in order to
obtain a release of GTI from any liability thereunder. To the extent necessary
to reduce or eliminate GTI's liability, Insulectro shall assume GTI's liability
as guarantor thereunder with respect to liabilities arising after the Close
unless included in the liabilities on the Closing Balance Sheet. GTI shall bear
the costs of any fees, costs or expenses charged by the lessors to review or
process such releases or assumption of liability.

         9.3.  Indemnification Procedures

                  9.3.1. Any party seeking indemnification (the "Indemnified
Party") shall give the party from whom indemnification is requested (the
"Indemnifying Party") written notice as promptly as practicable after the
Indemnified Party has received notice or knowledge of the matter that has given
or could give rise to a right of indemnification under this Agreement. Such
notice shall state the amount of losses, if any, and the method of computation
thereof, all with reasonable particularity and shall contain a reference to the
provisions of this Agreement in respect of which such right of indemnification
is claimed.

                  9.3.2. With respect to any losses arising from any third party
claim (a "Third Party Claim"), the Indemnified Party shall give the Indemnifying
Party written notice as promptly as practicable after receiving notice of any
Third Party Claim. If the Indemnifying Party acknowledges in writing its
obligation to indemnify the Indemnified Party hereunder against any losses that
may result from any Third Party Claim (subject to the limitations set forth in
this Article 9), then the Indemnifying Party shall be entitled, at its option,
to assume and control the defense of such Third Party Claim at its expense and
through counsel of its choice upon giving written notice of its intention to do
so to the Indemnified Party. In such case, the Indemnified Party shall be 
permitted, at its option, to participate in the defense of any such Third Party
Claim with counsel of its own choosing and at its own expense. If the 
Indemnifying Party does not elect to assume and control the defense of such 
Third Party Claim, then the Indemnified Party may, at its option, elect to 
assume and control such defense at the reasonable expense of the  

                                       24
<PAGE>   25
Indemnifying Party (subject to the consent of the Indemnifying Party, not to be
unreasonably withheld or delayed) and through counsel of the Indemnified Party's
choice. If the Indemnifying Party exercises its right to undertake the defense
of any such Third Party Claim as provided above, the Indemnified Party shall
cooperate with the Indemnifying Party and make available to the Indemnifying
Party all pertinent records, materials and information in its possession or
under its control as is reasonably requested by the Indemnifying Party.
Similarly, if the Indemnified Party rightfully undertakes the defense of any
Third Party Claim, the Indemnifying Party shall cooperate with the Indemnified
Party and make available to it all such records, materials and information in
the Indemnifying Party's possession or under its control relating thereto as are
reasonably requested by the Indemnified Party. No Third Party Claim may be
settled by the Indemnifying Party or the Indemnified Party without the written
consent, not to be unreasonably withheld or delayed, of the other party;
provided, however, that if such settlement involves the payment of money only
and the Indemnified Party is fully indemnified with respect to such payment and
the Indemnified Party refuses to consent thereto, the Indemnifying Party shall
cease to be obligated with respect to such Third Party Claim. In no event will
either party conduct the defense of any Third Party Claim in a manner that will
unreasonably detract from or otherwise interfere with or disrupt the other
party's business or customers.

                  9.3.3. The parties shall make appropriate adjustments for
insurance coverage in determining the amount of losses or claims for purposes of
this Article 9, provided that the indemnifiable losses shall then be increased
by any additional expense or liability associated with the obtaining of benefits
under such coverage, to the extent of and as a result of such losses or claims.

10.      TERMINATION AND ABANDONMENT.

(5) business days after notice of such violation from the Sellers;

                  10.1.4. By the Buyers if the Buyers have reasonably determined
that any of the conditions precedent in Article 6 have not been met or if the
Buyers have reasonably determined that the business, assets, or financial
condition of ESCO or Holdings, taken as a whole, have been materially and
adversely affected, whether by reason of changes, developments, or operations in
the ordinary course of business or otherwise;

                  10.1.5.  By the Sellers if the Sellers have reasonably
determined that any of the conditions precedent in Article 7 have not been met;

                  10.1.6. If the Agreement has not been consummated by February
16, 1996 then this Agreement may be terminated by any party to this Agreement at
any time thereafter, provided that such party seeking to terminate the Agreement
is not in breach of such party's duties and obligations under the Agreement.
