ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.

         (a)

                  On April 10, 1998, Heartland Technology, Inc. (the
"Registrant" or the "Company") entered into an Agreement and Plan of
Reorganization (the "Purchase Agreement"), by and among Solder Station-One,
Inc., a California corporation ("Solder Station"), Odilon Cardenas and Enedina
Cardenas (the stockholders of Solder Station, collectively referred to as the
"Founders"), the Company and SS Acquisition Corporation, a California
corporation and newly formed wholly owned subsidiary of the Company ("Merger
Sub").

                  Pursuant to the Purchase Agreement, Solder Station and Merger
Sub filed a Merger Agreement with the Secretary of State of the State of
California, whereupon Merger Sub merged with and into Solder Station (the
"Merger") and Solder Station (as the surviving corporation in the Merger) became
a wholly owned subsidiary of the Company, effective April 10, 1998.

                  Prior to the Merger, neither Solder Station nor the Founders
had any material relationship with the Company or any of its affiliates, any
director or officer of the Company, or any associate of any such director or
officer.

                  Pursuant to the Purchase Agreement and in consideration of the
Merger, the Company purchased from the Founders all of the shares of common
stock of Solder Station that were outstanding prior to the Merger for $7,460,000
(the "Aggregate Consideration"), excluding escrow fees of $5,310. The Aggregate
Consideration was determined as a result of arms-length negotiations and
consisted of the following: (i) cash in the amount of $5,185,000 (the "Cash
Consideration"); (ii) a promissory note made by Solder Station and Merger Sub,
in the aggregate principal amount of $1,700,000, payable in four semiannual
installments (the first three of which will be $400,000 and the last of which
will be $500,000) beginning eighteen months from the closing date of the
transaction (the "Closing Date"), with interest accruing at an annual rate of 8%
payable in arrears on the last day of each calendar quarter commencing on June
30, 1998, and guaranteed by the Company pursuant to a Continuing Guaranty
between Founders and the Company dated as of April 10, 1998 (the "Continuing
Guaranty"); (iii) a promissory note made by Solder Station and Merger Sub, in
the aggregate principal amount of $400,000, payable either one year from the
Closing Date or three years from the Closing Date if, and only if, Solder
Station meets certain operating income goals, and guaranteed by the Company
pursuant to

                                        2

the Continuing Guaranty; and (iv) a promissory note in the amount of $175,000
made by Solder Station and Merger Sub payable when and to the extent Solder
Station is able to collect on certain accounts receivables.

                  The source of $3,000,000 of the Cash Consideration was
financing obtained through a certain Loan and Security Agreement, dated April
10, 1998, by and between Solder Station, Merger Sub, and LaSalle National Bank
(the "Loan Agreement"). The Loan Agreement provides for revolving credit loans
in an aggregate principal amount not to exceed $1,500,000, an acquisition loan
in the principal amount of $900,000, and a term loan in the principal amount of
$1,200,000. The loans are secured by a lien on the assets of Solder Station and
a pledge of its stock. The loans are also guaranteed by the Company pursuant to
a Guaranty, dated as of April 10, 1998.


         (b)

                  In connection with the Merger, the Company acquired Solder
Station's equipment used in providing finishing services for printed circuit
boards. Solder Station will continuing using such equipment in providing such

Agreement and the CGCL, Newco shall be merged with and into the Company (the
"Merger"), which at and after the Effective Time shall be, and is sometimes

Corporations and delivered to and filed with the Secretary of State of the State
of California at the Closing

<PAGE>
in the manner provided under the CGCL. The Merger shall become effective (the
"Effective Time") upon the filing and recording of the Merger Agreement by the
Secretary of State of the State of California in accordance with the CGCL.

2.3 Effect of Merger. At the Effective Time, the separate existence of Newco
shall cease and Newco shall be merged with and into the Company, and the
Company, as the Surviving Corporation, shall possess all of the rights,
privileges, powers and franchises as well of a public as of a private nature,
and be subject to all the restrictions, disabilities and duties of each of the
Constituent Corporations as provided in Section 1107 of the CGCL.

2.4 Charter and Bylaws of Surviving Corporation. From and after the Effective
Time: (i) the Articles of Incorporation of the Surviving Corporation shall be
amended pursuant to the Merger Agreement; and (ii) the Merger shall have all the
effects provided by applicable law.

2.5 Taking of Necessary Action. Prior to the Effective Time, the Parties hereto

               CONSTITUENT CORPORATIONS, EXCHANGE OF CERTIFICATES

3.1 Aggregate Consideration. Subject to the adjustments described in the next
sentence, the entire consideration payable by Newco with respect to the Shares
of the Company shall be Seven Million Two Hundred Sixty Thousand Dollars
($7,260,000) (the "Aggregate Consideration") payable in accordance with Section
 . The Aggregate Consideration will be: (i) decreased by the amount equal to the
difference between Five Hundred Thousand Dollars ($500,000) minus the cash or
cash equivalent assets of the Company available as of the close of business of
the date of Closing; and (ii) increased by the amount equal to the difference
between the cash or cash equivalent assets of the Company available as of the

Million Four Hundred Sixty Thousand Dollars ($7,460,000). If the Company incurs
any undisclosed liability outside the ordinary course of business since November

Closing, and the Parties will negotiate in good faith appropriate adjustments to
be made to the Aggregate Consideration at the Closing without obligation on the
Founders' or the Company's part to agree to such adjustment or to proceed with
the Closing. Not later than the Closing, the Company shall deliver to Heartland
a statement (the "Closing Statement") setting forth the amounts of said cash
assets and liabilities, together with a certificate of an officer of the Company
certifying that the amounts set forth on the Closing Statement are accurate as
of the Closing in all material respects; provided that, any such inaccuracies
shall be reconciled to the actual amounts within ten (10) days after the
Closing. The Company may distribute to Founders any sums on or prior to Closing
so long as such distributions are reflected in the Closing Statement.

default or violation of any order, writ, judgment, injunction or decree of any
court or of any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign which

effect on the business or properties of the Company. There is no action, suit,

necessary permits, licenses, approvals and authorizations required to conduct
its business as conducted. There is no existing law, rule, regulation or order,

regulations or order, whether federal or state, which would prohibit or restrict
the Company in any material respect from, or otherwise materially adversely

5.9      INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS.

         (i) The Company owns or holds sufficient right, title or interest in
and to all patents, copyrights, technology, software, know-how, processes, trade
secrets, trademarks, service marks and trade names (collectively, "Intellectual
Property") used in or necessary for the conduct of the Company's business as
presently conducted (the "Company Intellectual Property") free and clear of all
liens, claims and encumbrances that would prohibit or restrict the Company from
conducting its business as currently conducted. The foregoing representation as
it relates to Third Party Technology (as hereinafter defined) is limited to the

                                       14
<PAGE>
Company's interest pursuant to Third Party Licenses (as hereinafter defined),
all of which are valid and enforceable and in full force and effect. The Company
Schedule contains an accurate and complete list and brief description of: (1)
all patents, trademarks (with separate listings of registered and unregistered
trademarks), tradenames, and registered copyrights, all applications for any of
the foregoing owned by or registered in the name of the Company; (2) all
Contracts relating thereto; (3) all Contracts with Persons relating to products
made, used, sold, marketed and/or distributed by the Company (the "Third Party
Licenses") relating to any Intellectual Property or technology that the Company
is licensed or otherwise authorized by such Persons to use, market, distribute
or incorporate into products or services marketed and distributed by the Company
to the extent, in each case, that the same is material to the conduct of the
business of the Company (such software, technology, know-how and processes being
hereafter collectively referred to as the "Third Party Technology"); and (4) all
Contracts pursuant to which the Company or any Founder agreed to restrictions on
the use or disclosure of any Company's or any Person's Intellectual Property, or
any restrictions from any conduct or business, materially relating to the nature
of the business conducted by the Company to the extent, in each case, that the
same is material to the conduct of the business of the Company. The transactions
expressly contemplated by this Agreement will not alter or impair any Company
Intellectual Property. No claims remain outstanding, are currently pending or,
to the best of the Company's knowledge, have been threatened or asserted against
the Company by any Person: (a) challenging the Company's use or distribution of
any products, software or Intellectual Property utilized by the Company in a
material fashion (including, without limitation, the Third Party Technology);
(b) challenging the validity or effectiveness of any license or agreement
relating thereto (including, without limitation, the Third Party Licenses); or
(c) challenging the scope, validity, enforceability, entitlement or the Company
ownership rights in the Company Intellectual Property. To the best of the
Company's knowledge, there is no valid basis for any claim of the type specified
in the immediately preceding sentence which would be reasonably expected to in
any material way adversely interfere with the continued exploitation by the
Company of any of its products or services. The use by the Company of any the
Company Intellectual Property and the conduct of the Company's business does not
infringe on the rights of, constitute misappropriation of, or unfair competition
with respect to any Intellectual Property or proprietary information or
intangible property right of any Person.

         (ii) The Company Schedule contains an accurate description or copy of
each Contract pursuant to which any Person has the right to manufacture,
reproduce, distribute, market or exploit any products of the Company, any
adaptations, translations, or derivative works based on such products or any
portion thereof or any Company Intellectual Property embodied in any of the
foregoing.

         (iii) Except for Third Party Technology and public domain technology,
all the Company Intellectual Property material to the business of the Company as
presently conducted, including designs, specifications, invention, source code,
object code, documentation, flow charts and diagrams were written, developed and
created solely and

                                       15
<PAGE>
exclusively by employees and consultants of the Company without the material
assistance of any other Person.

         (iv) To the best of the Company's knowledge, no employee or consultant
of the Company is in violation of any term of any employment or consulting
Contract to not disclose or assign any Company Intellectual Property or other
Contract relating to the nature of the business conducted by the Company.

5.10 TITLE TO PROPERTIES AND RELATED MATTERS. Without limiting the provisions of
Section hereof, the Company has good and marketable title to its properties and
assets reflected on the Balance Sheet or acquired by it since the date of the
Balance Sheet (other than properties and assets disposed of in the ordinary
course of business or as expressly contemplated by this Agreement since the date
of the Balance Sheet), and all such properties and assets are free and clear of
mortgages, pledges, security interests, liens, charges, claims, restrictions and
other encumbrances, except for liens for current taxes not yet due and payable
and minor imperfections of title, if any, not material in nature or amount and
not materially detracting from the value or impairing the use of the property
subject thereto or impairing the operations of the Company.

5.11 LEASEHOLD INTERESTS. Each agreement and lease to which the Company is a
Party or under which it is a lessee of any property, real or personal, is listed
in the Company Schedule and is a valid and subsisting agreement without any
material default of the Company thereunder and to the best knowledge of the
Company without any default thereunder of any other party thereto. No event has
occurred and is continuing which, with due notice or lapse of time or both,
would constitute a material default or event of default by the Company under any
such lease or agreement or, to the best knowledge of the Company, by any other
party thereto. The Company's possession of such property has not been disturbed
and no claim has been asserted against the Company adverse to its rights in such
leasehold interests.

5.12 INSURANCE. The Company Schedule lists all insurance policies maintained by
the Company along with types of coverage, the amounts of coverage and the
insurance carriers. To the best of the Company's knowledge, such amounts and
such coverage are reasonable against all risks usually insured against by
persons operating properties and businesses of a similar type, nature and size
to that of the Company in the localities where the Company's properties and
businesses are located. Such insurance is under valid and enforceable policies
issued by insurers of recognized responsibility and such policies will not in
any way be impaired, or terminate or lapse by reason of, this Agreement or the
transactions expressly contemplated herein. The Company has not done anything,
either by way of action or inaction, that invalidates such policies in whole or
in part.

5.13     TAXES.

         (i) The Company has properly and timely elected under Section 1362 of

         permit the borrowing by the Company of any sum of money except those
         reflected in the Financial Statements; and

communicated or threatened against the Company with respect to wrongful
termination of any dealer, distributor or any other marketing entity,
discriminatory pricing, price fixing, unfair competition, false advertising, or
any other violation of any laws or regulations relating to anti-competitive
practices or unfair trade practices of any kind and no specific situation, set
of facts, or occurrence provides any basis for any such claim.

conducted, to execute, deliver and perform its obligations under this Agreement
and the other Transaction Documents to which it is a Party, and this Agreement

Newco will constitute the legal, valid and binding obligations of Heartland and
Newco, enforceable in accordance with their terms, except as enforceability may

(regardless of whether such enforceability is considered in a proceeding in

warranties of the Founders, the Company, Heartland and Newco contained in
Sections , , and hereof and/or in any other certificate delivered by such

warranties in Section (Environmental Matters) shall survive Closing and continue
in full force and effect until five (5) years from the Closing, and the

<PAGE>

Notwithstanding the foregoing, any representation or warranty in respect of
which indemnity may be sought shall survive the time at which it would otherwise
terminate if notice given in good faith of the specific breach or inaccuracy
thereof giving rise to such indemnity may be sought, prior to such time. After
the Closing, the sole and exclusive remedy of any Party for any cause of action
for breach of any such representation or warranty or covenant set forth in
Sections ,
 or or elsewhere in this Agreement or certificates or agreements designated

11.2     INDEMNIFICATION OBLIGATIONS OF THE FOUNDERS.

respect to a person or entity shall mean all claims, demands, losses, costs,

and deficiencies (net of any insurance proceeds actually received) including,
without limitation, interest and penalties, attorneys fees and costs and all
amounts paid in settlement of any claim, action or suit.

         (ii) Each Founder, jointly and severally, agrees to indemnify and hold

officers, directors and shareholders, as the case may be, harmless against and
in respect of any and all Claims which may be asserted against Heartland, Newco

which arise out of: (a) the nonfulfillment of any material agreement, covenant
or obligation of such Founder to be performed under this Agreement or any other
Transaction Document to which such Founder is a Party; (b) the nonfulfillment of
any material agreement, covenant or obligation of the Company to be performed at
or prior to Closing under this Agreement; (c) the nonfulfillment of any material
agreement, covenant or obligation of the Co-Trustee of the Cardenas Family Trust

any breach of any representation or warranty pursuant to Section hereof made by
such Founder and pursuant to Section hereof made by the Founders and/or the
Company and contained herein or in any certificate required to be delivered by
the Company pursuant to Sections , and (excluding in all cases the Loan
Documents), or any other Transaction Document or in any certificate required to
be delivered by the Company pursuant thereto in any material respect (excluding
any and all certificates delivered in connection with or pursuant to the Loan
Documents); (e) any and all claims in respect of any and all Taxes of the
Company (excluding claims relating to sales taxes, real or personal property
taxes, and payroll taxes all of which are accrued but not delinquent as of the
day before the Closing) for all periods (or portions thereof) ending on or prior
to the day before the Closing Date, including a taxable year of the Company that
is deemed to close on the day before the Closing Date pursuant to Section
hereof; and (f) any damages or losses suffered by the Company resulting from any
and all claims of the Company against Stradling Yocca Carlson & Rauth that have

                                       39
<PAGE>
been released by the Founders on behalf of the Company pursuant to the
Engagement Letter and Fee Agreement: Waiver of Conflict of Interest letter from
Nick E. Yocca to the Founders dated March 3, 1998. The Founders shall have no
indemnification liability unless and only to the extent that Claims aggregate
more than One Hundred Fifty Thousand Dollars ($150,000) (provided the foregoing
limitations of this Section shall not apply to Claims arising from Section
(Authorized Capital Stock), Section (Taxes), Section (e) ("Tax Indemnity") or
Section (Transaction Expenses)) and are aggregately less than the amount that
has been paid and delivered to Founders in cash as Aggregate Consideration, net
of all disgorgeable amounts subject to trusts for benefit of the creditors of
the Company.

11.3 INDEMNIFICATION OBLIGATIONS OF HEARTLAND. In connection with this Agreement
and as a condition thereto, Heartland and Newco agree to indemnify and hold each
Founder and their successors, assigns or affiliates harmless against and in
respect of any and all Claims which may be asserted against such Founder or such
Founder shall incur or suffer which arise out of or relate to: (i) the
nonfulfillment of any material agreement, covenant or obligation of Heartland or
Newco to be performed in connection with this Agreement or any other Transaction
Document to which Heartland or Newco is a Party; (ii) any breach of any
representation or warranty made by Heartland or Newco and contained herein or in
any certificate delivered pursuant hereto or any other Transaction Document or
in any certificate delivered pursuant thereto in any material respect; and (iii)
any act or omission of the Company or Heartland or its agents or representatives
after the Closing, except with respect to Claims after the Closing that were
caused by or arose out of: (a) any unlawful act or omission of any Founder prior
to Closing; (b) any lease between the Company and the Founders and/or the
Cardenas Family Trust; and (c) any breach of the Founders' representations,
warranties and covenants under this Agreement at any time, and/or the Company's
representations, warranties, or covenants to be performed by the Company prior
to the Closing under this Agreement.

11.4     INDEMNIFIED CLAIMS.

         (i) Subject to the special procedures for third party claims set forth
in item "ii" listed below, whenever any Claim shall arise for indemnification
hereunder, the Party or Parties seeking indemnification (in each such case, the
"Indemnified Party") shall notify the Party or Parties from whom indemnification
is being sought (in each such case, the "Indemnifying Party") of such claim in
writing promptly and in no case later than thirty (30) days after such
Indemnified Party has actual knowledge of the facts constituting the basis for
such claim. Each Indemnified Party shall also so notify the Indemnifying Party
promptly and in no case later than fifteen (15) days after the commencement of
any legal proceedings with respect to any such Claim. The failure to so notify
the Indemnifying Party shall not relieve the Indemnifying Party from any
liability which it may have to any Indemnified Party to the extent the
Indemnifying Party is not prejudiced as a proximate result of such failure. Such
notice shall specify all facts known to such Indemnified Party giving rise to
the indemnification sought and the amount or an estimate of the amount of the
obligation or liability arising therefrom. Such notice shall also include
photocopies of all relevant communications received from third party claimants
and their attorneys. The right of such

                                       40
<PAGE>
Indemnified Party to indemnification hereunder and the estimated amount thereof,
as set forth in such notice, shall be deemed agreed to by the Indemnifying Party
unless, within sixty (60) days after such notice is given, such Indemnified
Party is notified in writing that the Indemnifying Party disputes the right to
indemnification as set forth or estimated in such notice, in which case the
Parties shall endeavor to settle and compromise the dispute within thirty (30)
additional days. In the event the Parties hereto are unable to agree after said
thirty (30) day period, the Parties shall be entitled to pursue litigation
pursuant to Section
 hereof.

         (ii) In case any action or any Claim is brought by a Person: (a) the
Indemnified Party against whom the Claim is brought shall provide prompt written
notice thereof to the Indemnifying Party obligated to indemnify such Claim; and
(b) the Indemnifying Party shall, upon the demand and at the option of the
Indemnified Party assume the defense thereof (at the expense of the Indemnifying
Party) within thirty (30) days or at least prior to the time a response is due
in such case, which ever occurs first, or, alternatively upon the demand and at
the option of the Indemnified Party, pay to such Party or Parties all costs and
expenses, including attorneys' fees, incurred by such Party or Paries in
defending itself or themselves, provided that the Indemnifying Party shall be
entitled to jointly control such proceedings or participate with and be advised
fully by the Indemnified Party, provided, however, that in any proceeding
relating to a Tax liability for which the Founders are obligated to indemnify
Heartland and Newco hereunder, Founders shall control such proceeding. If a
Party or Parties become obligated to assume the defense of any such Claims
pursuant to the foregoing sentence, then, the Indemnified Party entitled to be
indemnified shall be entitled to participate in said defense (at its or their
own expense). All Parties shall cooperate reasonably with each other in the
defense of any Claim brought by a third party, including making available all
records reasonably necessary to the defense of such Claim. The Indemnifying
Party shall be entitled to reasonable approval of the settlement of any Claim
with respect to which such Party may be liable hereunder.

         (iii) In the event Heartland and/or Newco has a Claim against one or
more Founders, Heartland and/or Newco may pursue the Claim against any such
Founder or all such Founders as Heartland and/or Newco shall determine in the
sole exercise of its discretion. In such an event, the Indemnifying Party or
Indemnifying Parties selected by Heartland and/or Newco shall promptly notify
the other Founders of such Claim and each of such Founders against whom
Heartland and/or Newco has such a Claim shall be entitled to participate in any
defense of such Claim as an Indemnifying Party pursuant to the terms of "ii"
immediately above. Under no circumstances shall a Founder be entitled to
contribution or indemnification from the Company arising from any Claim
hereunder by Heartland and/or Newco.

11.5     CHARACTER, EFFECT AND PAYMENT OF INDEMNITY PAYMENTS.

         (i) All amounts paid pursuant to this Section by a Party or Parties
(other than the Company) to another Party or Parties (other than the Company)
(other than interest payments) shall be treated by such Parties as an adjustment
to the consideration paid with respect to the portion of this Agreement or the
other Transaction Documents to which such indemnification payment (or portion
thereof) relates. If, contrary to the intent of the Parties as expressed in this
Agreement, any payment made pursuant to this Section is treated as taxable
income of the recipient, then the payor shall indemnify and hold harmless the
recipient from any net liability for taxes attributable to the receipt of such
payment. In determining the net liability for taxes of the Indemnified Party,
the Parties agree to take into account the deductibility by the recipient or its
affiliates of the item which gave rise to the indemnity payment. For purposes of
this Section, the Indemnified Party will be considered to be liable for tax in
respect of any payment treated as taxable income and any related deductible
expense at the highest marginal tax rate then in effect for corporations or
individuals, as the case may be, in the jurisdictions so characterizing the
payment for the year such payment is considered to be earned by the Indemnified
Party.

         (ii) Each amount determined to be payable by an Indemnifying Party to
an Indemnified Party under the terms hereof ("Indemnity") shall be paid in cash
to the Indemnified Party within forty-five (45) days after the date on which the
amount of such Indemnity and liability therefor is finally determined in
accordance with the terms hereof. Any notice for Indemnity provided in
accordance with Section hereof shall contain an itemization of the damages,
expenses, costs and liabilities comprising the Indemnity, certified to be true
and correct by the Indemnified Party or its legal representative.

11.6 EQUITABLE RELIEF. Each Party agrees that the breach of any of their
material obligations under this Agreement including, without limitation, the
applicable provisions of Sections , , , and hereof, may cause another Party
irreparable injury for which it would have not adequate remedy at law, and that
such other Party shall be entitled to specific performance or preliminary or
other injunctive relief in addition to any and all remedies it may otherwise be
entitled to at law or in equity.

11.7 CUMULATIVE. No remedy made available to Heartland or Founders hereunder by
and of the provisions of this Agreement is intended to be exclusive of any other
remedy, and each and every remedy shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or otherwise.

11.8     TAX MATTERS.

         (i) Each of the Founders, Heartland and Newco agree to treat any
indemnity payment made pursuant to this Section as an adjustment to the
Aggregate Consideration for federal, state, local and foreign income tax
purposes.


                                       42
<PAGE>
         (ii) For federal income tax purposes, the taxable year of the Company
shall end as of the close of the day immediately preceding the Closing Date and,
with respect to all other Taxes, the Founders, Heartland and Newco will, unless
prohibited by applicable law, close the taxable period of the Company as of the
close of the day immediately preceding the Closing Date. Neither the Founders,
nor Heartland, nor Newco shall take any position inconsistent with the preceding
sentence on any Tax Return. In any case where applicable law does not permit the
Company to close its taxable year on the day immediately preceding the Closing
Date or in any case in which a Tax is assessed with respect to a taxable period
which includes the day immediately preceding the Closing Date (but does not
begin or end on that day), then Taxes, if any, attributable to the taxable
period of the Company beginning before and ending after the day immediately
preceding the Closing Date shall be allocated (i) to the Founders for the period
up to and including the day immediately preceding the Closing Date, and (ii) to
Heartland for the period subsequent to the day immediately preceding the Closing
Date. Any allocation of income or deductions required to determine any Taxes
attributable to any period beginning before and ending after the day immediately
preceding the Closing Date shall be prepared by Heartland and shall be made by
means of a closing of the books and records of the Company as of the close of
the day immediately preceding the Closing Date, provided that exemptions,
allowances or deductions that are calculated on an annual basis (including, but
not limited to, depreciation and amortization deductions) shall be allocated
between the period ending on the day immediately preceding the Closing Date and
the period after the day immediately preceding the Closing Date in proportion to
the number of days in each such period. Heartland shall provide the Founders
with a schedule showing the proposed computation of the allocation at least
thirty (30) days prior to the due date for filing a Tax Return which includes
the day immediately preceding Closing Date. Founders shall be entitled to cash
equal to the amount of any refund or credit for pre-Closing periods and any such
amount shall be payable by Heartland to Founders, other than a refund resulting
from carry backs of any Tax Item from a Post-Closing Taxable Period to a Pre-
Closing Taxable Period (which refund shall be the property of the Company). The
Founders and their representatives shall have the right to review such schedule
and related books and records, and Heartland and Founders shall attempt in good
faith mutually to resolve any disagreements regarding the determination of such
allocation. Any amount owing from Founders or Heartland under this Section shall
be paid no later than five (5) days prior to the filing of the underlying Tax
Return.

         The Parties agree that it is their mutual intention that, for federal
and state income tax purposes, the Founders' receipt of the Aggregate
Consideration and the Notes shall be reported as a sale of the Shares, which are
a capital asset, and that the Parties shall not take a position inconsistent
with the foregoing on any Tax Return, except to the extent required under
applicable law or by controlling legal precedent.

         (iii) Heartland, Newco and the Founders agree to furnish or cause to be
furnished to each other, and each at their own expense, as promptly as
practicable, such information (including access to books and records) and
assistance, including making employees available on a mutually convenient basis
to provide additional information and explanations of any material provided,
relating to the Company as is reasonably necessary for the filing of any

                                       43
<PAGE>
Tax Return, for the preparation for any audit, and for the prosecution or
defense of any claim, suit or proceeding relating to any adjustment or proposed
adjustment with respect to Taxes. Heartland or the Company shall retain in its
possession, and shall provide the Founders reasonable access to (including the
right to make copies of), such supporting books and records and any other
materials that the Founders may specify with respect to Tax matters relating to
any taxable period ending on or prior to the Closing Date until the relevant
statute of limitations has expired. After such time, Heartland may dispose of
such material, provided that prior to such disposition Heartland shall give the
Founders a reasonable opportunity to take possession of such materials.


                             SECTION 12. TERMINATION

12.1 TERMINATION. This Agreement may be terminated and the transactions hereby

material breach by Heartland or Newco of any representation, warranty, covenant
or agreement of Heartland or Newco, respectively, set forth in this Agreement,

warranty, prior to the date on which the Company's conditions to Closing (other

by the Company or the Founders of any representation, warranty, covenant or
agreement of the foregoing set forth in this Agreement, which breach shall not

on which Heartland's or Newco's conditions to Closing (other than the accuracy
of the representation and warranty in question) would be satisfied or, in the
case of a covenant or agreement, within five (5) business days following receipt
by the Company and Founders of notice of such breach; or

         (iv) by either Heartland, Newco, the Company or the Founders:

                  (a) if a court of competent jurisdiction or governmental,
         regulatory or administrative agency or commission shall have issued an
         order, decree or ruling or taken any other action (which order, decree
         or ruling the Parties hereto shall use their best efforts to lift), in
         each case permanently restraining, enjoining or otherwise prohibiting
         the transactions contemplated by this Agreement, and such order,
         decree, ruling or other action shall have become final and
         nonappealable; or


                                       44
<PAGE>
                  (b) if the Closing shall not have occurred on or before April
         10, 1998; provided, however, that the right to terminate this Agreement
         pursuant to this Section 11 shall not be available to any Party whose
         material breach of this Agreement has been the cause of, or resulted
         in, the failure of the Closing to occur on or before such date.

abandonment of this Agreement prior to the Closing Date, written notice thereof

provisions of Section and any nondisclosure or confidentiality agreement

any other Party to this Agreement resulting from such termination except (i) the
provision of this Section
 shall remain in full force and effect and (ii) no Party waives any claim or
right against a breaching Party to the extent that such termination results from

to Chapter 5 of the California General Corporation Law or any statute

and governmental charges imposed upon its properties or upon the income or
profits therefrom (in each before the same become delinquent and before
penalties accrue thereon) and all claims for labor, materials or supplies which

material adverse effect on its business and financial conditions, unless and to
the extent that the same are being contested in good faith and by appropriate
proceedings and adequate reserves, determined in accordance with generally
accepted accounting principles, have been set aside on its books with respect
thereto;

                  (iv) comply with all applicable laws, rules and regulations of

                  (v) continue in force, with good and responsible insurance
companies, adequate insurance covering risks of such types and in such amounts
as are customary for other companies engaged in similar lines of business, the

administered in accordance with GAAP consistently followed, and set aside on its
books and cause each of its operating Subsidiaries to set aside on its books all

meaning assigned to that term in the Loan Agreement) of not less than 1.35:1 or

(the "Company"), and SS ACQUISITION CORPORATION, a California corporation
(collectively, "Borrower"), each jointly and severally hereby promises to pay to
the order of ODILON CARDENAS AND ENEDINA CARDENAS ("Holders"), individuals
residing in California, the principal amount of U.S. Four Hundred Thousand
Dollars (U.S. $400,000.00) (the "Principal"), pursuant to the terms and
conditions hereof.

1. Payment of Principal. Subject to the terms and conditions hereof, the
Principal shall be due and payable if, and only if, on the date that is: (i) one
(1) year from the Closing Date (as defined in the Agreement and Plan of
Reorganization dated as of April 10, 1998 among Solder Station-One, Inc.,
Holders, Heartland Technology, Inc. ("Heartland"), and SS Acquisition
Corporation (the "Purchase Agreement")), the Surviving Corporation's (as that
term is defined in the Purchase Agreement) Operating Income (as defined below)
for calendar year 1998 is equal to or exceeds One Million Five Hundred Nine
Thousand Dollars ($1,509,000.00); or (ii) three (3) years from the Closing Date,
the Company's aggregate Operating Income for calendar years 1998, 1999 and 2000
is equal to or greater than Six Million Twenty-Eight Thousand Dollars
($6,028,000.00). If the Company's Operating Income in calendar year 1998 is less
than One Million Five Hundred Nine Thousand Dollars ($1,509,000.00) and the
Company's aggregate Operating Income for calendar years 1998, 1999 and 2000 is
less than Six Million Twenty-Eight Thousand Dollars ($6,028,000.00), then the
Principal shall not become due and payable and this Note shall automatically
terminate. Operating Income shall be calculated using the income and expense
items incurred by Borrower in the ordinary course of business, which for
illustration are the items included on the income statement attached hereto as
Exhibit A, and shall not include any items derived from or resulting from any
future acquisition of a separate business (but shall include items resulting
from acquisitions of equipment to enhance or expand Borrower's business), any
expenses incurred in connection with the Purchase Agreement and the

transactions contemplated thereby, and any management or similar fees which
Heartland may charge to the Company. Borrower may, at any time and from time to
time, without premium or penalty, prepay all or any portion of the outstanding
Principal provided that partial prepayments shall be in the aggregate amount of
not less than Five Thousand Dollars ($5,000.00) or whole multiples in excess
thereof.

3. Payment Methods. All payments of the Principal hereunder shall be payable in
lawful money of the United States of America to Holders at the location
designated from time to time by Holders pursuant to Section 11 hereof in
immediately available funds by wire transfer to a bank account designated in
writing by Holders to Borrower on or within ten (10) days prior to the due date.
If any payment of Principal or interest on this Note shall become due on a
Saturday, Sunday or a bank or legal holiday, such payment shall be made on the
next succeeding business day.

4. Events of Defaults. To the extent that the conditions set forth in Sections
1(i) or 1(ii) are satisfied, the occurrence of any of the following shall
constitute an "Event of Default" under this Note:

         (a) Borrower defaults in payment of any Principal or interest accrued
thereon, when due and payable pursuant to the terms hereof and such defaults
continue for a period thirty (30) days thereafter without cure; or

         (b) Borrower, pursuant to the United States Bankruptcy Code or any
state or foreign bankruptcy or insolvency law: (1) commences a voluntary case,
consents to the entry of an order for relief against it in an involuntary case
or to the appointment of a trustee, receiver or custodian for all or
substantially all of its assets or makes a general assignment for the benefit of
its creditors; or (2) an involuntary case is commenced against Borrower in a
court of competent jurisdiction and such case is not dismissed within ninety
(90) days; or

         (c) Borrower materially defaults in the performance of any other
covenant, term or provision of this Note, or any representation made in this
Note is or becomes untrue, and such default continues for a period of thirty
(30) days after receipt by Borrower of written notice from Holders without cure;
or

         (d) Borrower fails to maintain a Debt Service Coverage Ratio (within
the meaning assigned to that term in the Loan and Security Agreement dated April
10, 1998 among LASALLE NATIONAL BANK and Borrower (the "Loan Agreement") of
greater than 1.35:1 or such greater ratio as may be required under any other
loan agreement of the Borrower in effect from time to time; provided that any
such failure causes Borrower's failure to make a payment under this Note when
such payment becomes due; or

         (e) The declaration of an "Event of Default" (within the meaning
assigned to that term in the Loan Agreement) or an event of default under any
other loan agreement of the Borrower in effect from time to time, subject in
each case to any applicable grace period; provided that such an Event of Default
under the Loan Agreement or such event of default

                                        2
<PAGE>

under this Note when such payment becomes due or causes such payment to be
disgorged.

         (f) Borrower or any creditor or any shareholder of Borrower, pursuant
to Chapter 5 of the California General Corporation Law or any statute
prohibiting distributions to shareholders or fraudulent conveyances, commences
an action against Holder; provided that if such action is commenced against
Holder by a creditor, it shall not constitute a default unless and until
Borrower shall have failed to defend such action or shall have not prevailed in
defending such action.

         (g) Borrower fails to perform any of its material obligations under the
Agreement Regarding Payment of Creditors dated April 10, 1998 among Borrower,
Heartland Technology, Inc., Solder Station-One, Inc., Odilon Cardenas and
Enedina A. Cardenas, and a creditor commences an action against Borrower in a
court of competent jurisdiction arising out of such Borrower's non-performance
and Heartland and/or Borrower fails to cure such non-performance within ninety
(90) days after its receipt of written notice of such action; provided that such
action shall not constitute a default unless and until Borrower shall have
failed to defend such action or shall have not prevailed in defending such
action.

5. Consequences of Default. Upon the occurrence of an Event of Default and such
Event of Default continues for thirty (30) days after Borrower's receipt of
written notice without cure, the entire amount then owing on this Note shall, at
the option of, and upon written notice from, Holders and, if not already due and
payable, become immediately due and payable. Upon the occurrence of an Event of
Default specified in Section 4(b), the entire amount then owing on this Note
shall become immediately due and payable without the necessity of any action by
Holders.

6. Nature of Note. Other than the condition set forth in Section 1, this Note is
an absolute and unconditional obligation of Borrower made in connection with the

waiver of any such right or remedy or any other right or remedy on any future
occasion.

thereof regarding conflict of laws. Each party hereby consents and submits to

California, and expressly agrees that the venue for any action arising under

faith:

                  (i)  assist in carrying out all those terms of the Note;

                  (ii) cause to be done all things necessary to maintain,
preserve and renew its corporate existence and all material licenses and permits
from government agencies necessary for the conduct of its business except where
the failure to so maintain, preserve or renew would not have a material adverse
effect on its business or financial condition;

                  (iii) pay and discharge, when payable, all taxes, assessments
and governmental charges imposed upon its properties or upon the income or
profits therefrom (in each before the same become delinquent and before
penalties accrue thereon) and all claims for labor, materials or supplies which
if unpaid might by law become a lien upon any of its property and would have a
material adverse effect on its business and financial conditions, unless and to
the extent that the same are being contested in good faith and by appropriate
proceedings and adequate reserves, determined in accordance with generally
accepted accounting principles, have been set aside on its books with respect
thereto;

                  (iv) comply with all applicable laws, rules and regulations of
all foreign and domestic governmental and regulatory authorities, the violation
of which would have a material adverse effect upon its businesses or financial
condition;

                  (v) continue in force, with good and responsible insurance
companies, adequate insurance covering risks of such types and in such amounts
as are customary for other companies engaged in similar lines of business, the

<PAGE>
                  (vi) maintain a system of accounting established and

such proper reserves as shall be required by GAAP;

                  (vii) maintain a Debt Service Coverage Ratio (within the
meaning assigned to that term in the Loan Agreement) of not less than 1.35:1 or
such greater ratio as may be required under any other loan agreement of the
Borrower or a subsidiary in effect from time to time to the extent the failure
to so maintain causes Borrower to fail to make payments under this Note when
such payments become due;

                  (viii) indemnify, defend and hold harmless Holders for any
claim, demand, obligation, loss, cost, expense, lien or judgment, arising from
the Subordination Agreement except to the extent that either Odilon Cardenas or
Enedina Cardenas' knowing and willful non-compliance with the Subordination
Agreement after specific notice and opportunity to cure within ninety (90) days;
and

                  (ix) maintain and keep its material properties in good repair,
working order and condition, and from time to time make all necessary or
desirable repairs, renewals and replacements, so that its business may be
properly conducted at all times, all to the extent consistent with ordinary past

consolidate with or merge into it, except with or into a wholly-owned subsidiary
or where the successor corporation will immediately thereafter have a net worth
of at least the greater of Five Million Dollars ($5,000,000.00) or the net worth
of Borrower immediately prior to such transaction and expressly assumes the
obligations under this Note; and

                  (ii) enter into any agreement which prohibits Borrower from
making the payment of the Note.

for other valuable considerations, the receipt and adequacy of each of which
Guarantor hereby acknowledges, Guarantor hereby unconditionally, irrevocably,
guarantees to Lender and its successors, endorsees, transferees, and assigns,

and performance of the Obligations, whether now or hereafter existing, and
whether for principal, interest, fees, expenses, or otherwise, howsoever
created, arising or evidenced, whether direct or indirect, absolute or
contingent or now or hereafter existing or due or to become due (including in
all cases all such amounts which would become due but for the operation of the
provisions of any Bankruptcy Law) with respect to the Obligations.

                           (b)      This Guaranty  constitutes a guaranty of 
payment and performance when due and not of collection, and Guarantor
specifically agrees that it shall not be necessary or required that Lender or
any of its successors, endorsees, transferees, or assigns assert any claim or
demand or enforce any remedy whatsoever against Borrower or any other Person
before or as a condition to the obligations of Guarantor under this Guaranty.

                  2.2 Absolute Guaranty. The Guaranty Obligations shall remain
                      -----------------
in full force and effect without regard to, and shall not be impaired or

or in part, of Lender's interest in and rights under the Note, including this

<PAGE>
                           (f)      any claim, defense,  counterclaim, or setoff
including, but not limited to, any defense or incapacity, disability, or lack of
corporate or other authority to execute any documents relating to the
Obligations or the Guaranty Obligations;

                           (g)      any cancellation, renunciation, or surrender
of any security or instrument at any time evidencing the Obligations or the
Guaranty Obligations;

                           (h)      Lender's vote, claim, distribution, 
election, acceptance, action, or inaction in any bankruptcy or reorganization
case related to the Obligations or the Guaranty Obligations;

                           (i)      any other action or circumstances that might
otherwise constitute a defense available to, or a legal or equitable discharge
of, any surety, guarantor or pledgor; or

                           (j)      the fact that any of the Obligations or the
Guaranty Obligations may become due or payable in connection with or by reason
of any agreement or transaction that may be illegal, invalid, or unenforceable
in whole or in part, it being agreed by each Guarantor that the Guaranty
Obligations shall not be discharged until the Guaranty Termination Date (and
then after the Guaranty Termination Date, the Guaranty Obligations shall be
subject to reinstatement under Section 5).

                  2.3 Demand by Lender. In addition to the terms set forth in
                      ----------------
Sections 2.1 and 2.2, and in no manner imposing any limitation on such terms,
but subject to the limitations referenced in Section 9, it is expressly
understood and agreed that, if any of the Obligations become immediately due and
payable, then Guarantor shall, upon demand in writing therefor by Lender to
Guarantor, immediately pay the Guaranty Obligations to Lender. Payment by
Guarantor shall be made to Lender to be credited and applied upon the
Obligations, in immediately available funds in lawful money of the United States
of America at 21702 Polynesian Lane, Huntington Beach, California 92646 or at
any other address or to any account designated by Lender that may be specified
in writing from time to time by Lender. Any payment received by Lender with
respect to the Obligations shall reduce the Guaranty Obligations by the amount
of such payment.

                  2.4 Guarantor Waivers.  In addition to any other waivers
                      -----------------
contained herein, Guarantor waives and agrees as follows:

                           (a)      The Guaranty Obligations are the  immediate,
direct, primary, and absolute liabilities of Guarantor. Guarantor expressly
waives any right it may now or in the future have (pursuant to Sections 2845 and
2850 of the California Civil Code or any other law, rule, arrangement or
relationship) to require Lender to, and Lender shall not have any obligations
to, first pursue or enforce against Borrower, any of the properties or assets of
Borrower or any other security, guaranty, or pledge that may now or hereafter be
held by Lender for the Obligations or for the Guaranty Obligations, or to apply
such security, guaranty, or pledge to the Obligations or to the Guaranty
Obligations, or to pursue any other remedy in Lender's power that Guarantor may
or may not be able to pursue itself and that may lighten Guarantor's burden.
Guarantor agrees that any notice or directive given at any time to Lender that
is inconsistent with the waiver in the immediately preceding sentence shall be
null and void and may be ignored by Lender, and, in addition, may not be pleaded
or introduced as evidence in any litigation or other dispute resolution
procedure relating to this Guaranty for the reason that such pleading or
introduction would be at variance with the written terms of this Guaranty,
unless Lender has specifically agreed otherwise in writing. Guarantor shall
remain liable for the Guaranty Obligations, notwithstanding any judgment Lender
may obtain against Borrower or Guarantor, or any other Person, except to the
extent the Obligations have been paid in full and such payment can be retained
by Lender free of any obligation to any creditors of Borrower or Guarantor of
the kind described in Section 5.
 
                                      4
<PAGE>

                           (b)      Guarantor has entered into this Guaranty 
based solely upon its independent knowledge of Borrower's financial condition
and Guarantor assumes full responsibility for obtaining any further information
with respect to such Person or the conduct of its business. Guarantor represents
that it is now, and during the term of this Guaranty will be, responsible for
ascertaining the financial condition of Borrower. Guarantor hereby waives any
duty on the part of Lender to disclose to Guarantor, and agrees that it is not
relying upon or expecting Lender to disclose to it, any fact known or hereafter
known by Lender relating to the operation or condition of Borrower or its
business or relating to the existence, liability, or financial condition of any
other Person. Guarantor knowingly accepts the full range of risk encompassed in
a contract of continuing guaranty, which risk includes the possibility that
Borrower may incur Obligations after Borrower's financial condition or its
ability to pay its debts as they mature has deteriorated.

                           (c)      Lender shall be under no obligation to
marshal any assets in favor of Guarantor or in payment of any or all of the
Obligations or the Guaranty Obligations.

                           (d)      Except as specifically  provided in Section
2.3 or as otherwise provided for in this Guaranty or applicable law, Guarantor
waives, to the fullest extent permitted by applicable law: (i) presentment,
demand and protest, and notice of presentment, dishonor, intent to accelerate,
acceleration, protest, default, nonpayment, maturity, release, compromise,
settlement, extension or renewal of the Note, or any others notes, commercial
paper, accounts, contract rights, documents, instruments, chattel paper and
guaranties at any time held by Lender on which Guarantor may in any way be
liable as a result of the Obligations, and hereby ratifies and confirms whatever
Lender may do in this regard; (ii) the benefit of all evaluation, appraisal and
exemption laws; (iii) notice of any extension, modification, renewal, or
amendment of any of the terms of the Note relating to the Obligations or the
Guaranty Obligations; (iv) notice of the occurrence of any default or event of
default with respect to the Obligations, the Guaranty Obligations or otherwise;
and (v) notice of any exercise or non-exercise by Lender of any right, power, or
remedy with respect to the Obligations or the Guaranty Obligations.

                           (e)      Guarantor  acknowledges  that it has been 
advised by counsel of its choice with respect to this Guaranty, the Note, the
Purchase Agreement and the transactions contemplated thereby.

                           (f)      Guarantor agrees that until the Guaranty
Termination Date it shall have no right of subrogation, reimbursement, indemnity
or contribution, all of which Guarantor expressly waives.

                           (g)      If Lender may, under applicable law, proceed
to realize its benefits under the Note, then Lender may, at its sole option,
determine which of its remedies or rights it may pursue without affecting any of
its rights and remedies under this Guaranty. If Lender bids at any foreclosure
or trustee's sale or at any public or private sale permitted by law, Lender may
bid all or less than the amount of the Obligations or the Guaranty Obligations
and the amount of such bid need not be paid by Lender but shall be credited and
applied as set forth in Section 7 unless such crediting is a violation under
applicable law or a breach by Lender of the Subordination Agreement. The amount
of the successful bid at any such sale, whether Lender or any other party
(including Guarantor) is the successful bidder, shall be deemed to be prima
facie evidence of the fair market value of the assets purchased and the amount
remaining after application of such bid amount in the manner set forth in
Section 7 shall be deemed to be prima facie evidence of the amount of the
Guaranty Obligations guaranteed under this Guaranty, notwithstanding that any
present or future law or court decision or ruling may have the effect of
reducing the amount of any deficiency claim to which Lender might otherwise be
entitled but for such bidding at any such sale.

                                       5
<PAGE>

                           (h)      Guarantor  agrees and represents that the
Obligations and Guaranty Obligations are and shall be incurred by Borrower and
Guarantor for business and commercial purposes only. Guarantor agrees that any
claim of Lender against Guarantor arising out of this Guaranty arises out of the
conduct by Guarantor of its trade, business, or profession. Guarantor undertakes
all the risks encompassed in the Note as they may be now or are hereafter agreed
upon by the parties thereto. Guarantor agrees that prior to the Guaranty
Termination Date (and for any period of reinstatement of this Guaranty after the
Guaranty Termination Date pursuant to Section 5), Lender, in such manner and
upon such terms and at such time as it deems best, and with or without notice to
Guarantor, may subordinate or release any security for the Obligations or the
Guaranty Obligations, whenever such action is taken pursuant to the terms of the
Note.

                           (i)      Guarantor waives and agrees that it shall
not at any time insist upon, plead, or in any manner whatever claim or take the
benefit or advantage of, any appraisal, valuation, stay, extension or redemption
laws, or exemption, whether now or at any time hereafter in force, which may
delay, prevent, or otherwise affect the performance by Guarantor of the Guaranty
Obligations or the enforcement by Lender of this Guaranty.

                           (j)      A separate  action or actions may be brought
and prosecuted by Lender against Guarantor whether or not an action is brought
against Borrower, or whether Borrower is joined in any such action or actions.
Without limiting the generality of the foregoing, Guarantor expressly waives the
benefit of any statute of limitations affecting the Obligations and expressly
agrees that the running of a period of limitation on, or Lender's delay or
omission in, any action by Lender against Borrower or for the enforcement of any
rights shall not exonerate or affect Guarantor's liability to pay and perform
the Guaranty Obligations.

                 2.5 Additional Waivers. Guarantor expressly acknowledges that:
                     ------------------

                           (a)      In  addition  to the  waivers  set forth in
Section 2.4, as solely between Guarantor and Lender and until the Obligations
have been paid in full and such payment can be retained by Lender free of any
obligation to any creditors of Borrower or Guarantor of the kind described in
Section 5, Guarantor also expressly, knowingly and intentionally waives and
relinquishes solely for the benefit of Lender any and all rights, defenses or
benefits Guarantor may have based upon an election of remedies by Lender which
in any manner impairs, affects, reduces, releases, destroys or extinguishes
Guarantor's subrogation rights or Guarantor's rights to proceed against Borrower
or against any other Person or any security for the Guaranty Obligations by way
of subrogation, indemnity, contribution, reimbursement or otherwise. In
particular, Guarantor agrees that, until the Obligations have been paid in full
and such payment can be retained by Lender free of any obligation to any
creditors of Borrower or Guarantor of the kind described in Section 5, this
Guaranty will remain fully effective and Guarantor will be liable to Lender for
any Guaranty Obligations even if Lender enforces any Lien that secures the
Obligations by means of a nonjudicial foreclosure, trustee's sale or power of
sale foreclosure and the effect of such sale is to prevent Guarantor from taking
any action against Borrower to recover any amounts paid by Guarantor to Lender
under this Guaranty or otherwise limits or destroys Guarantor's right of
subrogation.

                           (b) Until all Obligations have been performed in

                                       6
<PAGE>
full, Guarantor shall have no right to subrogation, and Guarantor expressly
waives solely for the benefit of Lender (i) any right (pursuant to Section 2848
of the California Civil Code or any other law, rule, arrangement or
relationship) to enforce any remedy which Lender now has or may hereafter have
against Borrower and (ii) any benefit of, and any right to participate in
(pursuant to Section 2849 of the California Civil Code or any other law, rule,
arrangement or relationship), any security that hereafter may be held by Lender.

         Guarantor also agrees that this Guaranty will remain fully effective
and Guarantor will be liable to Lender for any Guaranty Obligations until the
Obligations have been paid in full and such payment can be retained by Lender
free of any obligation to any creditors of Borrower or Guarantor of the kind
described in Section 5, even if Lender sells real property by judicial
foreclosure action and Guarantor's rights against Borrower are limited by the
operation of law.

                  2.6 Waivers of Defenses. Guarantor waives solely for the
                      -------------------
benefit of Lender any defense based upon or arising by reason of: (a) any
disability or other defense of Borrower or any other Person; (b) the cessation
of liability or limitation from any cause whatsoever of the Obligations or any
portion thereof, other than payment in full; (c) any lack of authority of any
agent or other person acting or purporting to act on behalf of Borrower, or any
defect in the formation of Borrower; (d) the application by Borrower of the
proceeds of the Obligations for purposes other than the purposes represented to,
or intended or understood by, Lender or Guarantor; (e) any act or omission by
Lender that directly or indirectly results in or aids the discharge of Borrower
or any portion of the Obligations by operation of law or otherwise; or (f) any
modification of the Obligations in any form whatsoever, including the renewal,
extension, acceleration or other change in time for payment of the Obligations,
or other change in the terms of the Obligations or any part thereof, including
increase or decrease of the rate of interest thereon.

                  2.7 Benefits of Guaranty. The provisions of this Guaranty are
                      --------------------
for the benefit of Lender and its successors, transferees, endorsees and
assigns, and nothing herein shall impair, as between Borrower, Guarantor, and
Lender, the Obligations. No such transfer, endorsement, or assignment shall
increase or diminish any of the Guaranty Obligations hereunder. This Guaranty
binds Guarantor, and Guarantor may not assign, transfer or endorse this Guaranty
except to any entity resulting from the merger or consolidation with Guarantor
or any entity that acquires substantially all of Guarantor's assets relating to
the Guaranty, provided that this Guaranty is assumed in writing and the
purchaser or resulting entity has a net worth of at least the greater of $5
million or the net worth of Guarantor immediately prior to such transaction. If
all or any part of the Obligations are transferred, endorsed, or assigned by
Lender to any Person or Persons, any reference to "Lender" herein shall be
deemed to refer equally to such Person or Persons.

                  2.8 Continuing Guaranty. Guarantor agrees that (a) this is a
                      -------------------
continuing guaranty, (b) this Guaranty shall remain in full force and effect
until the Guaranty Termination Date (and may be reinstated after the Guaranty
Termination Date pursuant to Section 5), and (c) the Guaranty Obligations
hereunder shall extend to each and every extension or renewal, if any, of the
Obligations.

                  2.9  Subordination.
                       -------------

                           (a)      Guarantor hereby agrees that, until the 
Guaranty Termination Date (and for any period during which this Guaranty is
reinstated pursuant to Section 5), all obligations and all indebtedness of
Borrower to Guarantor, including any and all present and future indebtedness

                                       7
<PAGE>
regardless of its nature or manner of origination now or hereafter to become due
and owing by Borrower to Guarantor (collectively, the "Subordinated
Indebtedness"), are hereby subordinated and postponed and shall be inferior, in
all respects, to the Guaranty Obligations.

                           (b)      In no  circumstance  shall any  Subordinated
Indebtedness be entitled to any collateral security; provided, that if any such
collateral security exists, Guarantor hereby agrees that any now existing or
hereafter arising Lien upon any of the assets of Borrower in favor of Guarantor,
whether created by contract, assignment, subrogation, reimbursement, indemnity,
operation of law, principles of equity or otherwise, shall be junior and
inferior to, and is hereby subordinated in priority to any now existing or
hereafter arising Liens in favor of Lender, regardless of the time, manner or
order of creation, attachment or perfection of the respective Liens.

                           (c)      Guarantor  hereby agrees that,  except as 
permitted by the Note or the Purchase Agreement, Guarantor shall not: (i)
assert, collect, accept payment on or enforce any of the Subordinated
Indebtedness or take collateral or other security to secure payment of the
Subordinated Indebtedness until the Guaranty Termination Date (and for any
period during which this Guaranty is reinstated pursuant to Section 5); (ii)
demand payment of, accelerate the maturity of, or declare a default or event of
default under the Subordinated Indebtedness until the Guaranty Termination Date
(and for any period during which this Guaranty is reinstated pursuant to Section
5); (iii) cause or permit Borrower to make or give, or receive or accept,
payment in any form (direct or indirect, including by transfer to an affiliate
or subsidiary of Borrower or Guarantor) on account of the Subordinated
Indebtedness, or make any transfers in respect of the Subordinated Indebtedness,
or give any collateral security for the Subordinated Indebtedness. Any payment,
transfer, or collateral security so made or given by Borrower and received or
accepted by Guarantor shall be held in trust by Guarantor for Lender, and
Guarantor shall immediately turn over, in kind, any such payment to Lender for
application in reduction of, or (in the case of property other than cash) as
security for, the Guaranty Obligations.

                           (d)      Lender acknowledges that this Guaranty is 
subordinated on and subject to the terms of the Subordination Agreement.

                           (e)      Lender hereby agrees that when and to the 
extent Guarantor commits a default under the two Promissory Notes made payable
by Guarantor to Peter VanHeusden dated May 30, 1997 in the aggregate principal
amount of Three Million Dollars ($3,000,000) plus interest now or hereafter
accruing thereon (the "Senior Notes") and Lender is notified in writing of the
existence of the default, and for such time as the default is continuing, Lender
subordinates any and all claims then or thereafter owing to it by Guarantor
under the Guaranty to any and all claims of Peter VanHeusden then owing under
the Senior Notes such that all events of default under the Senior Notes shall be
cured by Guarantor or waived by the holder of the Senior Notes before any
subsequent payment may be made on the Guaranty. Lender acknowledges that upon
and following written notice by Guarantor of any material default by Guarantor
that occurs after the date hereof as a result of non-payment under the Senior
Notes, any payment thereafter received by Lender from Guarantor pursuant to this
Guaranty will be held in trust for and remitted within a reasonable time to
Peter VanHeusden following such written notice. The subordinations effected, and
the rights created, hereby shall not be affected by (i) any amendment of or any
addition or supplement to any instrument, document or agreement relating to the
Senior Notes that does not accelerate their maturity or materially increase the
financial obligations thereunder, (ii) any exercise or non-exercise of any
right, power or remedy under or in respect of the Senior Notes or any
instrument, document or agreement relating thereto, and (iii) any waiver,
consent, release, indulgence, extension, renewal, modification, delay or other
action, inaction or omission in respect of the Senior Notes or any instrument,
document or agreement relating thereto, whether or not either Lender shall have
had notice or knowledge of any of the foregoing and regardless of whether Lender
shall have consented or objected thereto. Solder Station-One, Inc.'s business is
a "complementary business" as defined in the Senior Notes.

                  2.10 No Setoff, Defense or Counterclaim. Guarantor represents,
                       ----------------------------------
warrants and agrees that, as of the date of this Guaranty, the Guaranty
Obligations are not subject to any setoff or defense of any kind against Lender
or Borrower, and Guarantor specifically waives its right to assert any such
defense or right of setoff. Guarantor further agrees that the Guaranty
Obligations shall not be subject to any counterclaims, setoffs or defenses
against Lender or Borrower that may arise in the future. This Guaranty,
including without limitation this Section 2.10, shall not be deemed to be a
waiver by Guarantor or by or on behalf of Borrower of any term or provision in
the Purchase Agreement.

         3.       FURTHER ASSURANCES
                  ------------------

                  Guarantor agrees that it will, at its expense, upon the
written request of Lender, from time to time, promptly execute and deliver to
Lender any additional instruments or documents reasonably considered necessary
by Lender to cause this Guaranty to be, become, or remain valid and effective in
accordance with its terms.

         4.       PAYMENTS FREE AND CLEAR OF TAXES
                  --------------------------------

                  Any and all payments by or on behalf of Guarantor shall be
made, in accordance with this Section 4, free and clear of and without deduction
for any and all present or future Taxes. If Guarantor is required by law to
deduct any Taxes from or in respect of any sum payable hereunder to Lender, (i)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 4), Lender receives an amount equal to the sum it would have
received had no such deductions been made, (ii) Guarantor shall make such
deductions and (iii) Guarantor shall pay the full amount deducted to the
relevant taxing or other authority in accordance with applicable law. Upon
request by Lender, Guarantor shall furnish to Lender a receipt for any Taxes
paid by Guarantor pursuant to this Section 4 or, if no Taxes are payable with
respect to any payments required to be made by Guarantor hereunder, a
certificate from each appropriate taxing authority, if any. If Taxes are paid by
Lender as a result of payments under this Guaranty, Guarantor will, upon demand
of Lender, and whether or not such Taxes shall be correctly or legally asserted,
indemnify Lender for such payments, together with any interest, penalties, and
expenses in connection therewith plus interest thereon at such rate as agreed
between Lender and Guarantor.

         5.       REINSTATEMENT
                  -------------

                  This Guaranty shall remain in full force and effect and
continue to be effective, as the case may be, if at any time payment or
performance of the Obligations or the Guaranty Obligations, or any part thereof,
is, pursuant to the Subordination Agreement or applicable law, avoided,
rescinded or reduced in amount, or must otherwise be restored or returned by
Lender, or any other obligee of the Obligations or the Guaranty Obligations,
whether as a "voidable preference," "fraudulent conveyance," or otherwise, all
as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is avoided, rescinded, reduced, restored, or
returned, the Obligations or the Guaranty Obligations, as the case may be, shall
be reinstated and deemed reduced only by such amount paid and not so avoided,
rescinded, reduced, restored, or returned.

         6.       DEFAULTS AND REMEDIES
                  ---------------------

                                       9
<PAGE>

                  Upon the occurrence and during the continuance of an Event of
Default, as that term is defined in the Note, Lender may declare all of the
Guaranty Obligations, immediately and without demand, notice or legal process of
any kind, to be, and such Guaranty Obligations shall immediately become, due and
payable, and then, or at any subsequent time, Lender may exercise any or all of
its rights and remedies under this Guaranty, the Note or any applicable law, and
may, in addition make demand upon Guarantor for the payment of the Guaranty
Obligations.

         7.       APPLICATION OF PAYMENTS
                  -----------------------

                  Any payment made by Guarantor under this Guaranty shall be
applied by Lender first, to the satisfaction of Guarantor's indemnification
liabilities pursuant to Section 8, then to the payment of Obligations with
respect to accrued but unpaid interest on the Note, then to the payment of the
principal amount of the Note, and then to all other outstanding Obligations.

         8.       INDEMNIFICATION
                  ---------------

                  Guarantor (i) shall indemnify and hold harmless Lender (an
"Indemnified Person") from and against any and all suits, actions, fines,
deficiencies, penalties, proceedings, claims, damages, losses, liabilities,
expenses and Taxes (including reasonable attorneys' fees and disbursements and
other out-of-pocket costs of investigations or defense, including those incurred
upon any appeal) (each, a "Claim") that may be instituted or asserted against or
incurred by such Indemnified Person (A) arising out of the Guaranty Obligations
or any action to enforce payment of the Guaranty Obligations, or (B) arising out
of the Subordination Agreement except to the extent of Lender's willful and
knowing non-compliance with the Subordination Agreement, and (ii) shall
reimburse each Indemnified Person, for any legal or other out-of-pocket expenses
incurred in connection with investigating, defending or participating in any
such Claim, whether commenced or threatened (whether or not any such Indemnified
Person is a party to any action or proceeding out of which any such expenses
arise); provided, that Guarantor shall not be liable for any indemnification to
such Indemnified Person to the extent that any such Claim results solely from an
Indemnified Person's gross negligence or willful misconduct, as determined by a
final judgment of a court of competent jurisdiction. NEITHER LENDER NOR ANY
OTHER INDEMNIFIED PERSON NOR GUARANTOR NOR BORROWER SHALL BE RESPONSIBLE OR
LIABLE TO ANY OTHER PARTY HERETO, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY
BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY
THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES
WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED UNDER THE NOTE
OR OTHERWISE IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY. The
liabilities of Guarantor under this Section 8 shall survive the termination of
this Guaranty.

         9.       MISCELLANEOUS
                  -------------

                  9.1 Entire Agreement; Amendments. This Guaranty, together with
 
the Note and the Agreement Regarding Payment of Existing Creditors (a)
constitutes the entire agreement between the parties with respect to the subject
matter hereof, and (b) may not be amended or supplemented except by a writing
signed by Lender and Guarantor.

                  9.2 Section Titles. The section titles contained in this
Guaranty are and shall be without substantive meaning or content of any kind
whatsoever and are not a part of the agreement between the parties hereto.

                                       10

<PAGE>
                  9.3 Severability. In the event that any one or more of the
provisions contained in this Guaranty shall be determined to be invalid,
illegal, or unenforceable in any respect for any reason, the validity, legality,
and enforceability of any such provision or provisions in every other respect,
and the remaining provisions of this Guaranty, shall not be in any way impaired.

                  9.4 Conflict of Terms. If any provision of this Guaranty is
inconsistent with any provision of the Note, the Purchase Agreement, or any
other document or agreement contemplated therein, the provisions of this
Guaranty shall govern and control.

                  9.5 Non-Waiver. None of the liabilities of Guarantor, and no
right or remedy of Lender under this Guaranty, shall be deemed to have been
suspended or waived by Lender, nor shall Lender be estopped from asserting any
such right or remedy, by Lender's conduct or oral statements, but any such
suspension or waiver of any such right or remedy by Lender must be in writing
and signed by Lender. Any suspension or waiver by Lender of any of its rights or
remedies under this Guaranty shall not suspend or waive any prior or subsequent
right or remedy, whether of the same or of a different type.

                  9.6 Guaranty Termination Date. This Guaranty is a continuing
Guaranty that shall remain in full force and effect until the Guaranty
Termination Date, at which time this Guaranty shall terminate and be of no
further force and effect, subject to the reinstatement provisions of Section 5.

                  9.7 Limitation of Liability. Neither Lender nor any of its
officers, directors, partners, employees, agents, or counsel shall be liable for
any action lawfully taken or omitted to be taken by it or them under or in
connection with this Guaranty.

                  9.8 Governing Law. In all respects, including all matters of
construction, validity and performance, this Guaranty and the obligations
arising hereunder shall be governed by, and construed and enforced in accordance
with, the laws of the State of California applicable to contracts made and
performed in such state, without regard to principles thereof regarding
conflicts of laws.

                  9.9 Successors and Assigns. All covenants and agreements in
this Guaranty by or on behalf of any of the parties hereto shall bind and inure
to the benefit of the respective successors and assigns of the parties (the
"Transferee") hereto. Lender may assign any and all of its rights under this
Guaranty and the Note to any Transferee in connection with any assignment of all
or any portion of the Note and upon such assignment such Transferee shall be
entitled to all of the rights of Lender hereunder to the same extent as if such
Transferee were an original party hereof. Guarantor may not assign or transfer
its obligations under this Guaranty except as otherwise provided in Section 2.7
of this Guaranty.

                  9.10 Jurisdiction. Guarantor irrevocably consents and submits
to the jurisdiction of the United States District Court for the Central District
of California or a state court of the State of California sitting in Orange
County in any action or proceeding arising out of or in relation to this
Guaranty, and Guarantor irrevocably agrees that all claims in any such action
may be heard and determined in either such court. Guarantor irrevocably waives
any objection to the laying of venue in either such court and any objection on
the grounds that any such proceeding has been brought in an inconvenient forum,
and agrees and acknowledges that this Guaranty is made, delivered and to be
performed in Orange County, California.

         IN WITNESS WHEREOF, each of the parties hereto has caused this
Continuing Guaranty to be executed and delivered by its duly authorized officer
on the date first set forth above.

                           LOAN AND SECURITY AGREEMENT

         THIS LOAN AND SECURITY AGREEMENT (this "Agreement") is made as of the
10th day of April, 1998, by and between SOLDER STATION-ONE, INC., a California
corporation ("Solder Station"), and SS Acquisition Corporation, a California
corporation ("SSA") (together, Solder Station and SSA are referred to herein as
"Borrower"; all references to Borrower shall mean each of them, jointly and

Bank maintained for that purpose, which entries shall be rebuttably presumptive
evidence of such loans in the absence of manifest error.

                   (a) The unpaid principal amount of (i) each Revolving Loan

Loan until maturity (whether by acceleration or otherwise) at a rate per annum
which shall at all times be the Base Rate in effect from time to time, (ii) the
Acquisition Loan shall bear interest from the date of such Acquisition Loan

                   (b) Each LIBOR Loan shall be in a minimum amount of $100,000
or such greater amount which is an integral multiple of $20,000 and shall bear

payable in accordance with Paragraph 4.1(d) below. More than one LIBOR Loan may
be incurred on any Business Day; provided, that at no time shall there be
outstanding more than three (3) LIBOR Loans hereunder.

                   (c) If an Event of Default shall have occurred and be
continuing hereunder, all LIBOR Loans shall convert to Base Rate Loans and all

borrowing or reborrowing of LIBOR Loans for any Interest Period, shall promptly
notify Borrower thereof.

         4.2 Computation of Interest. Interest on each Loan shall be computed

         4.3       Conversion and Reborrowing of Loans; Interest Periods.

                   (a) Subject to the next following sentence, LIBOR Loans shall
mature and become due and payable on the last day of the Interest Period
applicable thereto. Following the end of an Interest Period, provided that no
Event of Default has occurred and is continuing, Borrower shall have the right,
subject to the terms and conditions of this Agreement, to reborrow through a new
LIBOR Loan in whole or in part, subject to Paragraph 4.1(b) above, any LIBOR
Loan from any current Interest Period into a subsequent Interest Period,
provided that Borrower shall give Bank notice of the reborrowing of any such
LIBOR Loan as provided in Paragraph 2.4 hereof; provided, that in the absence of
such notice, such LIBOR Loan shall be reborrowed hereunder as a Base Rate Loan.

                   (b) In the event that Borrower fails to give notice pursuant
to Paragraph 2.4 hereof to specify the Interest Period applicable to such
reborrowing, such Loan shall be reborrowed as a LIBOR Loan for a one (1) month
Interest Period; provided, if an Event of Default has occurred and is continuing
at the time any such LIBOR Loan is to be reborrowed hereunder, then such LIBOR
Loan shall be automatically reborrowed as a Base Rate Loan and interest shall
accrue thereafter at the Default Rate, unless the relevant LIBOR Loan is paid in
full on the last day of the then applicable Interest Period.

                   (c) Notwithstanding anything contained herein to the
contrary: (i) the initial Interest Period for any Borrowing of LIBOR Loans shall
commence on the date of such Borrowing (including the date of any conversion
from a Base Rate Loan) and each Interest Period occurring thereafter in respect
of such Borrowing shall commence on the day on which the next preceding Interest
Period expires; (ii) if any Interest Period begins on a day for which there is
no numerically corresponding day in the calendar month at the end of such
Interest Period, such Interest Period shall end on the last Business Day of such
calendar month; (iii) if any Interest Period would otherwise expire on a day
which is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day, provided if any Interest Period would otherwise expire
on a day which is not a Business Day, but is a day of the month after which no
further Business Day occurs in such month, such Interest Period shall expire on
the next preceding Business Day; (iv) no Interest Period shall extend beyond the
Maturity Date; and (v) no Interest Period may be elected at any time when an
Event of Default is then in existence.

         4.4 Change of Law. Notwithstanding any other provisions of this
Agreement or the Notes, if at any time Bank shall determine in good faith that
any change in applicable law or regulation or in the interpretation thereof
makes it unlawful or impossible for Bank to continue to maintain any LIBOR Loan,
Bank shall promptly give notice thereof (together with an explanation of the
reasons therefor) to Borrower, and the obligation of Bank to effect by
conversion or continue such LIBOR Loan under this Agreement shall terminate
until it is no longer unlawful or impossible for Bank to effect by conversion or
maintain such LIBOR Loan. Upon the receipt of such notice, Borrower may elect to
either (i) pay or prepay, as the case may be, the outstanding principal amount
of any such LIBOR Loan, together with all interest accrued thereon and all other
amounts payable to Bank under this Agreement, or (ii) convert the principal
amount of such affected LIBOR Loan to a Base Rate Loan available hereunder,
subject to the terms and conditions of this Agreement.

                                       16

         4.5 Unavailability of Deposits or Inability to Ascertain the LIBOR Rate
or Adjusted LIBOR Rate. Notwithstanding any other provision of this Agreement or
the Notes to the contrary, if prior to the commencement of any Interest Period
Bank shall determine in good faith (i) that deposits in the amount of any LIBOR
Loan scheduled to be outstanding are not available to Bank in the relevant
market or (ii) by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the LIBOR rate or
Adjusted LIBOR Rate, then Bank shall promptly give notice thereof to Borrower,
and the obligation of Bank to make or effect by conversion or continue any such
LIBOR Loan in such amount and for such Interest Period shall terminate until
deposits in such amount and for the Interest Period selected by Borrower shall
again be readily available in the relevant market and adequate and reasonable
means exist for ascertaining the LIBOR rate or Adjusted LIBOR Rate, as the case
may be. Upon the giving of such notice, Borrower may elect to either (i) pay or
prepay, as the case may be, the outstanding principal amount of any such LIBOR
Loan, together with all interest accrued thereon and all other amounts payable
to Bank in respect of Revolving Loans under this Agreement or (ii) convert the
principal amount of such affected LIBOR Loan to a Base Rate Loan available
hereunder, subject to all the terms and conditions of this Agreement.

         4.6       Yield Protection, Etc.

                   (a) Increased Costs. If (x) Regulation D of the Board of
Governors of the Federal Reserve System, or (y) the adoption of any applicable
law, treaty, rule, regulation or guideline, or any change therein, or any change
in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank or its lending branch with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency,

                           (i) shall subject Bank, its lending branch or any
         Loan to any tax, duty, change, stamp tax, fee, deduction, withholding
         or other charge in respect of this Agreement, any Loan, the Notes or
         the obligation of Bank to make or maintain any Loan, or shall change
         the basis of taxation of payments to Bank of the principal of or
         interest on any Loan or any other amounts due under this Agreement in
         respect of any Loan or its obligation to make or maintain any Loan
         (except for changes in the rate of tax on the overall net income of
         Bank imposed by the federal, state or local jurisdiction in which
         Bank's principal executive office or its lending branch is located);

                           (ii) shall impose, modify or deem applicable any
         reserve (including, without limitation, any reserve imposed by the
         Board of Governors of the Federal Reserve System), special deposit or
         similar requirement against assets of, deposits with or for the account
         of, or credit extended by, Bank; or

                           (iii) shall impose on Bank any penalty with respect
         to the foregoing or any other condition affecting this Agreement, any
         Loan, the Notes or the obligation of Bank to make or maintain any Loan;

and the result of any of the foregoing is to increase the cost to (or to impose
a cost on) Bank of making or maintaining any Loan, or to reduce the amount of
any sum received or receivable by Bank under this Agreement or under the Notes
with respect thereto, then Bank shall notify Borrower after

                                       17

<PAGE>

it receives final notice of any of the foregoing and, within forty-five (45)
days after demand by Bank (which demand shall be accompanied by a statement
setting forth the basis of such demand), Borrower shall pay directly to Bank,
such additional amount or amounts as will compensate Bank for such increased
cost or such reduction.

                   (b) Capital Adequacy. If, after the date hereof, either (i)
the introduction of or any change in or change in the interpretation of any law
or regulation or (ii) compliance by Bank with any guideline or request from any
central bank or other governmental authority (whether or not having the force of
law) affects or would affect the amount of capital required or expected to be
maintained by Bank or any corporation controlling Bank and Bank determines that
the amount of such capital is increased solely by or solely based upon the
existence of Bank's commitment to lend hereunder and other commitments of this
type, then, upon demand by Bank, Borrower shall immediately pay to Bank, from
time to time as specified by Bank, additional amounts sufficient to compensate
Bank in the light of such circumstances, to the extent that Bank reasonably
determines such increase in capital to be allocable to the existence of Bank's
commitment to lend hereunder.

         4.7 Funding Indemnity. In the event Bank shall incur any loss, cost or
expense (including, without limitation, any loss of profit and any loss, cost or
expense incurred by reason of the liquidation or re-employment of deposits or
other funds required by Bank to fund or maintain any LIBOR Loan or the relending
or reinvesting of such deposits or amounts paid or prepaid to Bank) as a result
of:

                   (a) any payment of a LIBOR Loan on a date other than the last
day of the then applicable Interest Period;

                   (b) any failure by Borrower to effect by conversion or
continue any LIBOR Loan on the date specified in the notice given pursuant to
Paragraph 2.4 hereof;

                   (c) any failure by Borrower to make any payment of principal
or interest when due on any LIBOR Loan, whether at stated maturity, by
acceleration or otherwise; or

                   (d) the occurrence of any Event of Default;

then, upon the demand by Bank, Borrower shall pay to Bank such amount as will
reimburse Bank for such loss, cost or expense. If Bank makes such a claim for
compensation under this Paragraph 4.7, Bank shall provide to Borrower a
certificate setting forth the amount of such loss, cost or expense in reasonable
detail.

         4.8 Discretion of Bank as to Manner of Funding. Notwithstanding any
provision of this Agreement to the contrary other than Paragraph 4.7, Bank shall
be entitled to fund and maintain its funding of all or any part of the LIBOR
Loans in any manner it sees fit.

         4.9 Interest Laws. Notwithstanding any provision to the contrary
contained in this Agreement or the Other Agreements, Borrower shall not be
required to pay, and Bank shall not be permitted to collect, any amount of
interest in excess of the maximum amount of interest permitted by law ("Excess
Interest"). If any Excess Interest is provided for or determined by a court of
competent jurisdiction to have been provided for in this Agreement or in any of
the Other
                                       18

<PAGE>
Agreements, then in such event: (a) the provisions of this Paragraph shall
govern and control; (b) Borrower shall not be obligated to pay any Excess
Interest; (c) any Excess Interest that Bank may have received and/or disbursed
to Bank hereunder shall be, at Bank's option, (i) applied as a credit against
the outstanding principal balance of Borrower's Liabilities or accrued and
unpaid interest (not to exceed the maximum amount permitted by law), (ii)
refunded to the payor thereof, or (iii) any combination of the foregoing; (d)
the interest rate(s) provided for herein shall be automatically reduced to the
maximum lawful rate allowed from time to time under applicable law (the "Maximum
Rate"), and this Agreement and the Other Agreements shall be deemed to have been
and shall be reformed and modified to reflect such reduction; and (e) Borrower
shall not have any action against Bank for any damages arising out of the
payment or collection of any Excess Interest. Notwithstanding the foregoing, if
for any period of time interest on any Borrower's Liabilities is calculated at
the Maximum Rate rather than the applicable rate under this Agreement, and
thereafter such applicable rate becomes less than the Maximum Rate, the rate of
interest payable on such Borrower's Liabilities shall remain at the Maximum Rate
until Bank shall have received the amount of interest which Bank would have
received during such period on such Borrower's Liabilities had the rate of
interest not been limited to the Maximum Rate during such period.

                             5. LOANS: GENERAL TERMS

         5.1 Payments to Bank; Defaulting Bank. That portion of Borrower's
Liabilities consisting of: (a) principal payable on account of the Loans made by
Bank to Borrower pursuant to this Agreement shall be payable by Borrower to

(ii) as provided herein in the Acquisition Note in respect of the Acquisition
Loan, and (iii) as provided in the Term Note in respect of the Term Loan; (b)
costs, fees and expenses payable pursuant to this Agreement shall be payable by
Borrower to Bank on demand; (c) interest payable pursuant to this Agreement

as and when provided in this Agreement or the Other Agreements.

         5.2 Automatic Debit. In order to cause timely payment to be made to
Bank of all Borrower's Liabilities as and when due, Borrower hereby authorizes
and directs Bank to debit the amount of such Borrower's Liabilities to any
ordinary deposit account of Borrower at Bank (including, without limitation, by
increasing the principal balance due under the Revolving Loan).

         5.3 Application of Payment. Subject to Paragraph 13.3 below and except
as otherwise specified herein, Borrower shall, at the time of making each
payment under this Agreement or any Note (whether by account debit or
otherwise), specify to Bank the Loan or other amounts payable by Borrower
hereunder to which such payment is to be applied (and in the event that it fails
to so specify, or if an Event of Default has occurred and is continuing, Bank
may allocate such payment in such manner as it may determine to be appropriate).
Notwithstanding the foregoing, all prepayments shall be applied to the amounts
due hereunder in the inverse order of their maturities.

         5.4 Conditions Precedent Events. Each Loan made by Bank to Borrower at
the request of Borrower pursuant to this Agreement or the Other Agreements shall
in any event be subject to the following conditions precedent: (a) there shall
not then exist an Event of Default (as hereinafter defined) or any event or
condition which with notice, lapse of time and/or the making of such Loan would
constitute an Event of Default; (b) the representations and warranties of
Borrower (after

                                       19
<PAGE>



giving effect to the consummation of the Acquisition) contained in this
Agreement shall be true and correct as of the date of such Loan with the same
effect as though made on such date; (c) all of the covenants and agreements of
Borrower in this Agreement, and all of the requirements of this Agreement with
respect to such Loan, shall have been complied with; and (d) there shall not
have occurred, since the date of this Agreement, any material adverse change in
the financial condition, results of operations or business of Borrower. Each
Borrowing by Borrower hereunder shall be deemed a representation and warranty by
Borrower that the foregoing conditions have been fulfilled as of the date of
such borrowing. Bank shall have received upon request a certificate signed by an
Authorized Officer of Borrower dated the date of such requested Loan certifying
satisfaction of the conditions specified in clauses (a)-(d) of this Paragraph
5.4.

         5.5 Offset. Borrower agrees that, in addition to (and without
limitation of) any right of set-off, bankers' lien or counterclaim Bank may
otherwise have, Bank shall be entitled, at its option, to offset balances held
by it for account of Borrower at any of its offices, in United States Dollars or
in any other currency, against any principal of or interest on any of Bank's
Loans, or any other amount payable to such Bank hereunder, which is not paid
when due (regardless of whether such balances are then due to Borrower), in
which case it shall promptly notify Borrower thereof, provided that such Bank's
failure to give such notice shall not affect the validity thereof.

         5.6 Discretionary Disbursements. Bank, in its sole and absolute
discretion, may immediately upon notice to Borrower, disburse any or all
proceeds of Loans made or available to Borrower pursuant to this Agreement
and/or the Other Agreements to pay any fees, costs, expenses or other amounts
required to be paid by Borrower hereunder and not so paid. All monies so
disbursed by Bank shall be a part of Borrower's Liabilities, payable by Borrower
on demand.

         5.7 Credit Termination Date; Continuance of Obligations, Etc. This
Agreement, Bank's obligation to loan monies to Borrower, and Borrower's ability
to borrow monies from Bank shall be in effect until the Termination Date.
Notwithstanding the foregoing and until such date when Borrower's Liabilities
shall be paid in full, Borrower's obligations hereunder and under the Other
Agreements shall continue, interest shall continue to be paid in accordance with
the foregoing, Bank shall be entitled to retain its security interest in the
Collateral and Bank shall retain all of its rights and remedies under this
Agreement.

         5.8 Over-Advances. If, at any time and for any reason, the aggregate
amount of Borrower's Liabilities in respect of Revolving Loans outstanding
hereunder exceeds the Revolving Credit Commitment (an "Over-Advance"), then upon
receipt of notice to Borrower by Bank, Borrower shall immediately pay to Bank,
the amount of such Over-Advance. If such Over-Advance remains outstanding for
more than one (1) Business Day after receipt of the aforesaid notice, until such
Over-Advance is so repaid to Bank, an Event of Default shall be deemed to have
occurred hereunder and the amount of such Over-Advance shall bear interest at
the applicable Default Rate.

         5.9 Lock-Box and Blocked Account. Upon the occurrence of an Event of
Default, upon the written request of Bank, Borrower shall establish a lock box
and cash collateral depository account (collectively, the "Blocked Account") in
Borrower's name with Bank to which all Obligors shall directly remit all
payments on Accounts Receivable and Collateral and in which Borrower will
immediately deposit all payments made for services rendered or other payments
constituting proceeds of Collateral in the identical form in which such payment
was made, whether by cash or

                                       20
<PAGE>

check. All payments made to the Blocked Account shall be the sole and exclusive
property of Bank and no persons shall have a right to setoff against the Blocked
Account. Bank will apply against Borrower's Liabilities two (2) Business Days
after the date of receipt, if received in the Blocked Account and by Bank's
commercial note teller prior to 2:00 p.m., Chicago time, all payments received
thereon, including cash, solvent credits, collections of Accounts Receivable,
proceeds of Collateral and any other amounts; provided that (a) Bank shall
charge back to Borrower any payments that may be required to be returned to the
entity making such payment and Borrower shall continue to pay interest on the
amount charged back from the date that such payment was applied against
Borrower's Liabilities; and (b) Bank shall have the exclusive right to determine
how, when and in what amounts application of such payments and such credits
shall be made on Borrower's Liabilities, and such determination shall be
conclusive upon Borrower.

         5.10      Prepayments; Prepayment Penalty; Etc.

                   (a) Voluntary Prepayments -- Revolving Loans. Borrower shall
have the right to prepay Revolving Loans in whole or in part, without premium or
penalty, from time to time on the following terms and conditions: (i) the
Borrower shall give Bank, at its Address for Notices (on the signature page
hereof), written notice (or telephonic notice promptly confirmed in writing) of
its intent to prepay the Revolving Loans, the amount of such prepayment and (in
the case of LIBOR Loans) the specific Borrowing(s) pursuant to which made, which
notice shall be given by the Borrower at least one (1) Business Day prior to the
date of such prepayment with respect to Base Rate Loans and two (2) Business
Days prior to the date of such prepayment with respect to LIBOR Loans; (ii) each
partial prepayment of any Borrowing shall be in an aggregate principal amount of
at least $200,000 and, if greater in an integral multiple of $100,000; and (iii)
at the time of any prepayment of LIBOR Loans pursuant to this Paragraph 5.10(a)
on any date other than the last day of the Interest Period applicable thereto,
Borrower shall pay the amounts required pursuant to Paragraph 4.1(d) and
Paragraph 4.7.

                   (b) Voluntary Prepayments -- Acquisition Loan and Term Loan.
Borrower shall have the right at any time to prepay in full, but not in part,
either or both of the Acquisition Loan and the Term Loan on the following terms
and conditions: (i) Borrower shall give Bank, at its Address for Notices (on the
signature page hereof), written notice (or telephonic notice promptly confirmed
in writing) of its intent to prepay either or both of such Loans, the amount of
such prepayment and whether such Loan(s) being prepaid is the Acquisition Loan,
the Term Loan or both, which notice shall be given by Borrower at least thirty
(30) Business Days prior to the date of such prepayment. In view of the
impracticality and extreme difficulty of ascertaining actual damages and by
mutual agreement of the parties as to a reasonable calculation of Bank's lost
profits, an early termination fee shall be paid by Borrower on the amount of the
Acquisition Loan and/or Term Loan being prepaid (the "Early Termination Fee"),
which Early Termination Fee shall be equal to:

                           (i) if such termination occurs prior to the first
         anniversary of the date hereof, an amount equal to three percent (3%)
         of the principal amount of Loans being prepaid; or

                           (ii) if such termination occurs on or after the first
         anniversary, but prior to the second anniversary of the date hereof, an
         amount equal to two percent (2%) of the principal amount of Loans being
         prepaid; or

                                       21

<PAGE>

                           (iii) if such termination occurs on or after the
         second anniversary, but prior to the third anniversary hereof, an
         amount equal to one percent (1%) of the principal amount of Loans being
         prepaid.

         5.11 Unused Portion Fee. To compensate Bank for the cost of reserving
funds to be made available to Borrower under this Agreement, Borrower shall pay
to Bank, for the benefit of Bank, on the last day of each fiscal quarter an
unused revolving line fee (the "Unused Portion Fee") equal to the sum of the
daily amounts by which the maximum aggregate principal amount of the Revolving
Credit Commitment exceeds the actual principal amount of all Revolving Loans
made hereunder. The Unused Portion Fee is calculated for each applicable day of
such quarter in an amount equal to the excess of the maximum aggregate principal
amount of the Revolving Credit Commitment over the principal amount of all
outstanding advances under the Revolving Loans on such day, multiplied by
one-quarter of one percent (1/4%). All fees and charges imposed on Borrower
pursuant to this Agreement including, without limitation, the Unused Portion Fee
accrued through the date of termination, shall be nonrefundable to Borrower,
notwithstanding any prepayment and termination by Borrower of this Agreement.

         5.12 Transaction Fee. On or prior to the Closing Date, Borrower shall
pay a fee of Thirty- One Thousand Five Hundred Dollars ($31,500) in the
aggregate (the "Transaction Fee") to Bank, which fee is comprised of Ten
Thousand Dollars ($10,000) in respect of the Revolving Credit Commitment,
Thirteen Thousand Dollars ($13,000) in respect of the Acquisition Credit
Commitment and Eight Thousand Five Hundred Dollars ($8,500) in respect of the
Term Credit Commitment.

                         6. LOANS: CONDITIONS TO LENDING

         6.1 Initial Loan Conditions Precedent. In addition to those conditions
set forth in Paragraph 5.4 above with respect to all Loans and advances
hereunder, prior to or contemporaneously with the making of the initial advance
of funds, Bank's obligation to make any Loan is subject to the satisfaction of
the following conditions precedent:

                   (a) Fees and Expenses. Borrower shall have paid all fees owed
to Bank and reimbursed Bank for all expenses due and payable hereunder on or
before the date hereof including, but not limited to, the Transaction Fee and
counsel fees provided for in Paragraph 13.12 hereof.

                   (b) Documents. Bank shall have received the following
documents, in form and substance satisfactory to Bank, and all of the
transactions contemplated by each such document shall have been consummated or
each condition contemplated by each such document shall have been satisfied:

                           (i) Related Documents. Copies of this Agreement as
         required by Bank and one copy of each of the Revolving Note, the
         Acquisition Note and the Term Note payable to Bank conforming to the
         requirements hereof duly executed by Borrower. The applicable Forms
         UCC-1 and UCC-2 financing statements related to the Collateral (as
         herein defined) shall have been filed in all jurisdictions that Bank
         deems necessary or advisable.

         action taken by Borrower or any other Person in response to (A) any
         Hazardous Material on, under or about any Facility, the existence of
         which is reasonably likely to give rise to an Environmental Claim, or
         (B) any Environmental Claim that could have a material adverse effect
         on Borrower, (iv) Borrower's discovery of any occurrence or condition
         on any real property adjoining or in the vicinity of any Facility that
         could be reasonably expected to cause such Facility or any part thereof
         to be subject to any restrictions on the ownership, occupancy,
         transferability or use there of under any Environmental Laws, and (v)
         any request for information from any governmental agency indicating
         that such agency has initiated an investigation as to whether Borrower
         may be potentially responsible for a Release or threatened Release of
         Hazardous Materials.

                           (iv) Promptly notify Bank of (i) any acquisition of
         stock, assets, or property outside of the ordinary course of business
         by Borrower that reasonably could be expected to expose Borrower to, or
         result in, Environmental Claims that could have a material adverse
         effect or that could be expected to have a material adverse effect on
         any Governmental Authorization then held by Borrower, and (ii) any
         proposed action outside of the normal course of business to be taken by

         that could subject Borrower to additional laws, rules or regulation,
         including, without limitation, laws, rules and regulations requiring
         additional environmental permits or licenses.

                   (f)     Financial Covenants.  Maintain the following 
financial covenants:

                           (i) Maintain a Net Worth (measured as of the end of
         each calendar year) of not less than One Million Five Hundred Thousand
         Dollars ($1,500,000), determined in accordance with GAAP, which amount
         shall increase by Three Hundred Seventy-Five Thousand Dollars
         ($375,000) on January 1, 1999 and Five Hundred Thousand Dollars
         ($500,000) as of January 1 of each year commencing January 1, 2000.

                           (ii) Maintain a Debt Service Coverage Ratio of not
         less than 1.35:1, determined in accordance with GAAP; provided,
         however, that in the event Borrower fails to maintain a Debt Service
         Coverage Ratio of not less than 1.35:1, it shall not be deemed a breach
         of this covenant if, and only if, immediately upon the occurrence of
         such failure, Borrower immediately ceases making any payments in
         respect of the Subordinated Note, whether in respect of principal,
         interest or otherwise, in accordance with the Subordination Agreement.
         Notwithstanding the foregoing, this covenant shall be breached in any
         event (and an Event of Default shall be deemed to have occurred) if
         Borrower fails to maintain a Debt Service Coverage Ratio of not less
         than 1.25:1. Such Debt Service Coverage Ratio shall be measured at the
         end of each calendar quarter on a rolling four (4) quarter basis taking
         into account the immediately preceding four (4) quarters, except that
         for the first three (3) full fiscal quarters after the Closing Date,
         Debt Service Coverage Ratio shall be measured at the end of each
         calendar quarter for the calendar quarter then ended.

                                       38

<PAGE>



                           (iii) Maintain EBITDA of not less than One Million
         Five Hundred Thousand Dollars ($1,500,000), measured at the end of each
         calendar quarter on a rolling four (4) quarter basis taking into
         account the immediately preceding four (4) quarters.

                           (iv) Cause Guarantor to maintain a Tangible Net Worth
         of Guarantor, at all times, at a level equal to or greater than
         Seventeen Million Dollars ($17,000,000).

                   (g)     Insurance.

                           (i) At its sole cost and expense, keep and maintain
         business interruption insurance and public liability and property
         damage insurance relating to its business and properties and their
         ownership and use of the Collateral (the "Insurance Coverage"). All
         such policies of insurance shall be in form and with insurers
         recognized as adequate by prudent business persons and all such
         policies shall be in amounts no less than such policies set forth on
         Schedule 11.1(bb) or as otherwise may be reasonably satisfactory to
         Bank. Borrower shall deliver to Bank the original (or certified) copy
         of each policy of insurance, or a certificate of insurance, and
         evidence of payment of all premiums for each such policy on or prior to
         the date of this Agreement. Such policies shall: (A) contain a lender's
         loss payable clause naming Bank as loss payee and additional insured as
         its interest may appear; (B) be accompanied by a lender's loss payable
         clause endorsement, executed by the applicable insurer, in form and
         substance acceptable to Bank; and (C) provide that the insurance
         companies will give Bank at least thirty (30) days written notice
         before any such policy or policies of insurance shall be altered or
         canceled.

                           (ii) In the event Borrower at any time or times
         hereafter shall fail to obtain or maintain any of the policies of
         insurance required above, provide evidence of Insurance Coverage as
         required by this Agreement or to pay any premium in whole or in part
         relating thereto, then Bank after giving five (5) days' prior notice to
         Borrower, without waiving or releasing any obligation or Event of
         Default by Borrower hereunder, may at any time or times thereafter (but
         shall be under no obligation to) obtain and maintain such policies of
         insurance and pay such premium and take any other action with respect
         thereto which Bank deems advisable to protect Bank's interests in the
         Collateral. All sums so disbursed by Bank, including reasonable
         attorneys fees, court costs, expenses and other charges relating
         thereto, shall be part of Borrower's Liabilities, payable by Borrower
         to Bank on demand. Borrower authorizes Bank, in Bank's sole discretion,
         to cause such sums to be paid by making an advance in the amount
         thereof to Borrower under the Revolving Credit Commitment and paying
         the proceeds thereof to Bank. Such insurance may, but need not, protect
         Borrower's interests, and Bank shall be under no obligation to so
         protect Borrower's interests. The Insurance Coverage that Bank
         purchases on behalf of Borrower may not pay any claim that Borrower
         makes or any claim that is made against Borrower in connection with the
         Collateral. Borrower may later cancel any Insurance Coverage purchased
         by Bank, but only after providing Bank with evidence that Insurance
         Coverage has been obtained as provided for in this Agreement. In the
         event Bank purchases all or any portion of the Insurance Coverage for
         the Collateral or as otherwise required hereunder, Borrower will be
         responsible for all costs and expenses of such Insurance Coverage,
         including, but not limited to, interest and any other charges imposed
         by Bank in connection with the purchase of the Insurance Coverage,
         until the effective date of the cancellation or expiration of the
         Insurance

                                       39

<PAGE>



         Coverage. The costs and expenses of any Insurance Coverage purchased by
         Bank shall be added to Borrower's Obligations. Borrower acknowledges
         that the cost of the Insurance Coverage purchased by Bank pursuant
         hereto may be more than the cost of insurance Borrower may be able to
         obtain on their own. Borrower shall deliver to Bank, in kind, all
         instruments representing proceeds of insurance received by Borrower.
         Bank may apply any insurance proceeds received at any time to the cost
         of repairs to or replacement of any portion of the Collateral and/or,
         at Bank's option, to payment of or as security for any of the
         Obligations, whether or not due, in any order or manner as Bank
         determines.

                   (h) Leases. Maintain and comply with all leases covering the
Collateral used by Borrower, including, without limitation, the leases related
to any leased property, in accordance with their terms so as to prevent any
default thereunder which may result in the exercise or enforcement of any
landlord's or other lien against Borrower.

                   (i) Union Contracts. Provide Bank with copies of all executed
collective bargaining agreements or other union contracts, if any, in effect as
of the date hereof and all additions, modifications or amendments thereto and
shall provide Bank with evidence of the renewal of any such agreements or
contracts prior to their expiration.

         11.3 Negative Covenants. At all times prior to the Termination Date and
thereafter for so long as any amount is due or owing to Bank hereunder, unless
Bank shall otherwise consent in writing, Borrower (after giving effect to the
consummation of the Acquisition) shall not:

                   (a) Liens, Etc. Create or suffer to exist, any Lien, other
charge or encumbrance, or any other type of preferential arrangement, upon or
with respect to any of its Collateral and properties, whether now owned or

Liens of Bank arising under this Agreement and (ii) the permitted Liens set

                   (b) Maintain Existence, Merger, Etc. (i) dissolve or

course of business); or (iii) together with one or more Affiliates convey,
transfer, lease or otherwise dispose of (whether in one transaction or in a
series of transactions) all or substantially all of the assets of Borrower and
such Affiliates (whether now owned or hereafter acquired) to any Person; or (iv)
purchase, lease or otherwise acquire all or substantially all of the assets or
properties of, or acquire any capital stock, equity interests, debt or other
securities of any Person, or enter into any joint venture or become a partner in
any partnership; or (v) engage in any transaction out of the ordinary course of
business; or (vi) merge or consolidate with any Person; provided, however, that
SSA and Solder Station may consummate the Acquisition and the other transactions
contemplated by the Purchase Agreement, pursuant to and in strict accordance
with the Purchase Agreement;

                   (c) Sale and Lease-Back. Enter into any arrangement with any
Person or to which such Person is a party providing for the leasing by Borrower
or any Affiliate of any principal asset which has been or is to be sold or
transferred by Borrower or such Affiliate to such Person or

                                       40

<PAGE>



to any other Person to whom funds have been or are to be advanced by such Person
on the security of such property or rental obligations of Borrower or such
Affiliate, other than sales or transfers between Borrower and any Affiliate or a
lease for a temporary period not to exceed twelve (12) months.

                   (d) Change in Control. Permit any Change in Control to occur.

                   (e) Funded Debt. Incur, create, assume, become or be liable
in any manner with respect to or permit to exist, any Funded Debt, except for

or loans in or to any other Person, except for (i) salaries and reasonable
advances of money to its employees in payment of reasonable expenses incurred by
such employees in the ordinary course of business or (ii) investments in
certificates of deposits of a banking institution having a net worth in excess
of $100,000,000 or in securities of the United States of America or commercial

Investments").

                   (g) Guaranties. Guaranty, endorse or otherwise in any way

liabilities of any other Person, except endorsements of negotiable instruments
for collection in the ordinary course of business.

                   (h) Stock and Dividends. Redeem, retire, purchase or
otherwise acquire, directly or indirectly, any Stock of Borrower or other
evidence of ownership interest, or declare or pay dividends or distributions
upon any Stock of Borrower or make any distribution of Borrower's property or
assets.

                   (i) Transactions with Affiliates or Insiders. Enter into, or
be a party to, any transaction with any Affiliate, stockholder or member of
Borrower, except in the ordinary course of and pursuant to the reasonable
requirements of Borrower's business and upon fair and reasonable terms which are
fully disclosed to Bank and are no less favorable to Borrower than would obtain
in a comparable arm's length transaction with a Person not an Affiliate,
stockholder or member of Borrower, as applicable.

                   (j) Capital Structure and Line of Business. Make any change

<PAGE>



                   (m) Inter-Company Transfers. Make any loans, transfers or
advances of funds to, or borrow any funds from, any Affiliate of Borrower;
provided, however, that prior to the occurrence of an Event of Default, Borrower
may engage in any such inter-company transfers with Affiliates having an
aggregate amount outstanding (whether in one transaction or a series of
transactions) of no more than Three Hundred Thousand Dollars ($300,000).

         11.4 Maintenance of Accounts. Borrower agrees to maintain its primary
operational accounts with Bank and shall maintain an average balance of
collected, available funds in a non-interest bearing demand deposit account with
Bank (the "Operating Account") in an amount at least equal to that amount
required to compensate Bank for its services in maintaining such account.
Borrower acknowledges that Bank will charge Borrower standard service charges in
effect from time to time for various services performed by Bank in connection
with any aspect of the relationship between Borrower and Bank, and Borrower
hereby agrees that if such service charges exceed the credit to Borrower arising
from earnings attributable to funds on deposit with Bank in the applicable
Operating Account, such service charge deficiency shall be deducted by Bank from
Borrower's Operating Account, monthly, in arrears, within ten (10) days
following the end of each month. Bank may cause interest and other amounts
payable on the obligations of Borrower to Bank hereunder to be paid by making a
direct charge to the applicable Operating Account in accordance with the terms
hereof.

<PAGE>



Borrower recognizes that in the event Borrower fails to perform, observe or
discharge any of its obligations or liabilities under this Agreement or the
Other Agreements, no remedy of law will provide adequate relief to Bank, and
agree that Bank shall be entitled to temporary and permanent injunctive relief
in any such case without the necessity of proving actual damages or the posting
of bond, surety or other security.

         12.6 Notice of Collateral Disposition. Any notice required to be given

intended action by Bank, deposited in the United States mail, postage prepaid
and duly addressed to Borrower at its principal place of business specified on

proposed action, shall constitute commercially reasonable and fair notice to
Borrower thereof.

         12.7 Matters Regarding Sale of Collateral. Upon an Event of Default,
Borrower agrees that Bank may, if Bank deems it reasonable, postpone or adjourn
any such sale of the Collateral from time to time by an announcement at the time
and place of sale or by announcement at the time and place of such postponed or
adjourned sale, without being required to give a new notice of sale. Borrower
agrees that Bank has no obligation to preserve rights against prior parties to
the Collateral. Further, Borrower waives and releases any cause of action and
claim against Bank as a result of Bank's possession, collection or sale of the
Collateral, any liability or penalty for failure of Bank to comply with any
requirement imposed on Bank relating to notice of sale, holding of sale, or
reporting of sale of the Collateral, and any right of redemption from such sale;
provided, however, nothing in this Paragraph shall be deemed a waiver of any
cause of action or claim against Bank as a result of Bank's failure to dispose
of the Collateral in a commercially reasonable manner.

         12.8 Replevin. In the event Bank seeks possession of the Collateral
through replevin or other court process, Borrower hereby irrevocably waives: (a)

any demand for possession of the Collateral prior to commencement of any suit or
action to recover possession thereof.

         12.9 Application of Proceeds. Except as otherwise herein expressly
provided, the proceeds of any collection, sale or other realization of all or
any part of the Collateral pursuant hereto, and any other cash of Borrower at
the time held by Bank hereunder, shall be applied by Bank:

                   First, to the payment of the costs and expenses of such
         collection, sale or other realization, including out-of-pocket costs
         and expenses of Bank and the fees and expenses of its representatives
         and counsel, and all expenses incurred and advances made by Bank in
         connection therewith;

                   Next, to the payment in full of Borrower's Liabilities; and

         assigns, or as a court of competent jurisdiction may direct, of any
         surplus then remaining.

         As used in this Paragraph, "proceeds" of Collateral shall mean cash,
securities and other property realized in respect of, and distributions in kind
of, Collateral, including any amount

                                       44

received under any reorganization, liquidation or adjustment of debt of Borrower
or any issuer of or obligor on any of the Collateral.

                                   13. GENERAL

         13.1 Payment Application Date. Any check, draft, or similar item of
payment by or for the account of Borrower delivered to Bank on account of
Borrower's Liabilities shall be applied by Bank on account of Borrower's
Liabilities on the date final settlement thereof is reflected by irrevocable

         13.2 Statement of Account. Each statement of account by Bank delivered
to Borrower relating to Borrower's Liabilities shall be presumed correct and
accurate, absent manifest error, and shall constitute an account stated between
Borrower and Bank unless, within ninety (90) days after Borrower's receipt of
said statement, Borrower delivers to Bank, by registered or certified mail
addressed to Bank at its Address for Notices specified on the signature pages
hereto, written objection thereto specifying the error or errors, if any,
contained in any such statement.

         13.3 Manner of Application; Waiver of Setoff Prohibition. During the
existence of an Event of Default, Borrower waives the right to direct the
application of any and all payments at any time or times hereafter received by
Bank on account of Borrower's Liabilities and Borrower agrees that Bank shall
have the right, in its absolute and sole discretion, to apply and re-apply any
and all such payments in such manner as Bank may deem advisable, notwithstanding
any entry by Bank upon any of its books and records. Borrower further waives any
right under or benefit of any law that would restrict or limit the right or
ability of Bank to obtain payment of Borrower's Liabilities, including any law
that would restrict or limit Bank in the exercise of its right to appropriate
any indebtedness owing from Bank to Borrower and any deposits or other property
of Borrower in the possession or control of Bank and apply the same toward or
setoff the same against the payment of Borrower's Liabilities.

         13.4 Survival of Representations and Warranties. Borrower covenants,
warrants and represents to Bank that all representations and warranties of
Borrower contained in this Agreement and the Other Agreements shall be true at
the time of Borrower's execution of this Agreement and the Other Agreements and
shall survive the execution, delivery and acceptance thereof by the parties
thereto and the closing of the transactions described therein or related
thereto.

         13.5      Integration; Amendment; Assignment.

                   (a) This Agreement and the Other Agreements constitute the
entire agreement and understanding between the parties relating to the subject
matter hereof and supersede all prior agreements, whether oral or written. This
Agreement and the Other Agreements may not be modified, altered or amended
except by an agreement in writing signed by Borrower and Bank, and no provision
of this Agreement may be waived except with the written consent of Bank.

                   (b) Borrower may not sell, assign or transfer this Agreement,
or the Other Agreements or any portion thereof, including without limitation
Borrower's rights, titles, interests, remedies, powers and/or duties hereunder

                   (c) Bank may assign or sell or agree to sell to one or more
other Persons a participation in all or any part of any Loan held by it or Loans
made or to be made by it.

         13.6 No Waiver. Bank's failure at any time or times hereafter to
require strict performance by Borrower of any provision of this Agreement shall
not waive, affect or diminish any right of Bank thereafter to demand strict
compliance and performance therewith. Any suspension or waiver by Bank of an
Event of Default by Borrower under this Agreement or the Other Agreements shall
not suspend, waive or affect any other Event of Default by Borrower under this
Agreement or the Other Agreements, whether the same is prior or subsequent
thereto and whether of the same or of a different type. None of the
undertakings, agreements, warranties, covenants or representations of Borrower
contained in this Agreement or the Other Agreements and no Event of Default by
Borrower under this Agreement or the Other Agreements shall be deemed to have
been suspended or waived by Bank unless such suspension or waiver is by an
instrument in writing by Bank specifying such suspension or waiver and given
pursuant to the requirements of Paragraph 13.5 hereof.

         13.7 Severability. If any provision of this Agreement or the Other
Agreements or the application thereof to any Person or circumstance is held
invalid or unenforceable, the remainder of this Agreement and the Other
Agreements and the application of such provision to other Persons or
circumstances will not be affected thereby and the provisions of this Agreement
and the Other Agreements shall be severable in any such instance.

         13.8 Successors and Assigns. This Agreement and the Other Agreements
shall be binding upon and inure to the benefit of the respective successors and
assigns of Borrower and Bank. This provision, however, shall not be deemed to
modify Paragraph 13.5 hereof.

         13.9 Conflict with Other Agreements. The provisions of the Other
Agreements are incorporated in this Agreement by this reference thereto. Except
as otherwise provided in the Other Agreements by specific reference to the
applicable provision of this Agreement, if any provision contained in this
Agreement is in conflict with, or inconsistent with, any provision in the Other
Agreements, the provision contained in this Agreement shall govern and control.

         13.10 No Impairment by Termination. Except to the extent provided to
the contrary in this Agreement and in the Other Agreements, no termination or
cancellation (regardless of cause or procedure) of this Agreement or the Other
Agreements shall in any way affect or impair the powers, obligations, duties,
rights and liabilities of Borrower or Bank in any way or respect relating to (a)
any transaction or event occurring prior to such termination or cancellation,
(b) the Collateral and/or (c) any of the undertakings, agreements, covenants,
warranties and representations of Borrower contained in this Agreement or the
Other Agreements. All such undertakings, agreements, covenants, warranties and
representations shall survive such termination or cancellation.

         13.11 Waivers. Except as otherwise specifically provided in this

entitled to receive with respect to this Agreement or the Other Agreements by
virtue of any applicable statute or law and waives presentment, demand and
protest and notice of presentment, protest, default, dishonor, non-payment,

submitted by Borrower to Bank (for Bank's acceptance or rejection thereof) at
Bank's principal place of business as an offer by Borrower to borrow monies from

         If in the reasonable judgment of Bank said security or any additions
thereto or substitutes therefor or any part thereof, shall have depreciated in
value, or if Borrower shall have failed or refused to make full and prompt
payments, when due, of any Obligations of Borrower, the payment of which is
guaranteed hereunder, after the expiration of all cure and grace periods, the
Bank, at its option, shall have full power at any time and from time to time to
sell, assign and deliver the whole of said property and all additions thereto
and substitutes therefor, or any part of said property, additions and
substitutes at any public or private sale, and without advertising the same and
without notice to Guarantor, and with the right of the Bank to be a purchaser at
any such sale or sales, and in the event of any sale or purchase hereunder no
matter by or to whom made, all notice thereof, and any and all equity or right
of redemption, whether before or after sale hereunder is hereby expressly
waived; and, after deducting all legal and other costs and expenses, including
reasonable attorneys' fees, from the proceeds of such sale or sales, to apply
the remainder on any Obligations of Borrower, or of Guarantor covered hereby
whether due or not, as the Bank shall deem proper, and return the surplus, if
any, to Guarantor.

         4. Representations, Warranties and Promises. Guarantor represents,
warrants and promises as follows:

                  (a) Guarantor is a duly organized and validly existing
corporation in good standing under the laws of the State of Delaware and has and

and be bound by this Guaranty and has duly executed and delivered this Guaranty.



<PAGE>


                  (b) The execution and delivery by Guarantor of this Guaranty,
Guarantor's performance of all of its obligations hereunder and consummation of
the transactions contemplated hereby do not conflict with or violate any
applicable law or any ruling, judgment or order of any court or other
governmental authority, and do not and will not conflict with or result in or
constitute any breach or default under or result in the creation or imposition
of any lien, charge or encumbrance under any agreement, indenture or undertaking
to which Guarantor is a party or by which Guarantor or any of its property is
bound.

                  (c) There is no action, suit, proceeding, inquiry or
investigation, at law or in equity, before or by any court or other governmental
authority, pending or, to the knowledge of Guarantor, threatened against or
affecting Guarantor or any of its property, which has, or would have, a material
adverse effect upon the financial condition of Guarantor.

                  (d) No approval, consent or authorization of any governmental
authority is required in connection with Guarantor's entering into or performing
its obligations under this Guaranty.

                  (e) This Guaranty constitutes the legal, valid and binding
obligation of Guarantor, enforceable against Guarantor in accordance with its
terms.

         5. Events of Default. The occurrence of any one or more of the
following events shall constitute and be defined as an "Event of Default"
hereunder:

                  (a) Any failure by Guarantor to observe or perform any
covenant, agreement, or condition under, contained in or referred to in this
Guaranty in accordance with the terms hereof, after any cure or grace period has
expired.

                  (b) Any failure of a representation or warranty of Guarantor
contained or referred to in this Guaranty to be true and correct as of the date

occurred.

                  (e) The cessation to do business as a going concern, the
liquidation or the dissolution, of Guarantor.

                  (f) The appointment of a receiver for any part of the property

         6. Rights of Parties Upon Default. Upon the occurrence of an Event of
Default hereunder, all Obligations shall, at the election of Bank, become
immediately due and payable, without notice to Guarantor, together with interest
thereon as provided in the instruments representing such Obligations and, in
addition, Bank shall have all the rights and remedies provided under the Notes,
the Loan Agreement, the Other Agreements, other provisions hereof and any other
applicable law. No remedy of Bank herein is intended to be exclusive of any
other available remedy or remedies, but each and every such remedy shall be
cumulative and shall be in addition to every other remedy given under this
Guaranty or now or hereafter existing at law or in equity or under any other
agreement. Bank, in its sole discretion, shall have the right to proceed first
and directly against Guarantor under this Guaranty without proceeding against
Borrower or any other person or any property, without exhausting any other
remedies which it may have and without resorting to any other security held by
or otherwise available to Bank. Each and every Event of Default shall give rise
to a separate cause of action hereunder, and separate suits may be brought
hereunder as each cause of action arises, but it shall not be necessary for Bank
to sue on each and every cause. No delay or omission to exercise any right or
power accruing upon any Event of Default shall impair any such right or power or
shall be construed to be a waiver thereof, but any such right or power may be
exercised from time to time and as often as may be deemed expedient. No course
of dealing between Guarantor and Bank nor any delay in exercising any rights
hereunder or under the Notes, the Loan Agreement or the Other Agreements shall
operate as a waiver of any rights of Bank. In the event any provision contained
in this Guaranty should be breached by Guarantor and thereafter duly waived by
Bank such waiver shall be limited to the particular breach so waived and shall
not be deemed to waive any other breach hereunder. No waiver, amendment, release
or modification of this Guaranty shall be established by conduct, custom or
course of dealing, but solely by an instrument in writing duly executed by the
parties thereto. In the event any payment by Borrower to Bank is held to be a
preference under the bankruptcy laws, or if for any other reason Bank is
required to refund such payment or pay the amount thereof to any other person,
firm or corporation, such payment by Borrower to Bank shall not constitute a
release of Guarantor from any liability respecting payment of the Obligations
guaranteed hereby, and Guarantor agrees to pay such amount to Bank upon demand.

         7.       Waiver.

                  (a) Waiver by Bank of any Event of Default hereunder, or of
any breach of the provisions of this Guaranty by Guarantor, shall not constitute
a waiver of any other Event of Default or breach, nor of the same Event of
Default or breach on a future occasion. No delay or omission on the part of Bank
in the exercise of any right or remedy hereunder shall operate as a waiver of
such right or remedy, nor shall the exercise of any right or remedy preclude
later or further exercise thereof. All rights or remedies of Bank on account of
the Collateral or on account of any of the Obligations, whether arising under
this Guaranty or otherwise, shall be cumulative and non-exclusive of each other,
and may be exercised by Bank at such times and in such order as Bank may
determine.



<PAGE>


                  (b) Guarantor hereby waives presentment, demand, diligence,
protest and notice of dishonor and protest and any other notice with respect to
any and all of the Obligations and waives acceptance of this Guaranty by Bank
and waives notice of and consent to and agrees that its obligations hereunder
and Bank's rights hereunder shall not be affected by one or more extensions or
renewals or modifications of any of the Obligations or the exercise of any and
all rights, powers, options, privileges and authorities granted to Bank by law
or by the terms of any instruments evidencing such obligations or otherwise. No
waiver or modification or amendment to the terms of this Guaranty shall be
effective as against Bank unless the same is in writing and signed by Bank.

         8. GUARANTOR WAIVES THE BENEFIT OF ANY LAW THAT WOULD OTHERWISE
RESTRICT OR LIMIT BANK IN THE EXERCISE OF ITS RIGHTS, WHICH ARE HEREBY
ACKNOWLEDGED, TO APPROPRIATE WITHOUT NOTICE, AT ANY TIME HEREAFTER, ANY
INDEBTEDNESS MATURED OR UNMATURED, OWING FROM BANK TO GUARANTOR AFTER EXPIRATION
OF ALL CURE PERIODS. BANK MAY, FROM TIME TO TIME, WITHOUT DEMAND OR NOTICE OF
ANY KIND, APPROPRIATE AND APPLY TOWARD THE PAYMENT OF SUCH OF THE OBLIGATIONS,
AND IN SUCH ORDER OF APPLICATION AS THE BANK MAY, FROM TIME TO TIME, ELECT ANY
AND ALL SUCH BALANCES, CREDITS, DEPOSITS, ACCOUNTS, MONEYS, CASH EQUIVALENTS AND
OTHER ASSETS, IN THE NAME OF GUARANTOR, THEN OR THEREAFTER WITH BANK. GUARANTOR
HEREBY ASSIGNS AND TRANSFERS TO BANK ANY AND ALL CASH, NEGOTIABLE INSTRUMENTS,
DOCUMENTS OF TITLE, CHATTEL PAPER, SECURITIES, CERTIFICATES OF DEPOSIT, DEPOSIT
ACCOUNTS, OTHER CASH EQUIVALENTS AND OTHER ASSETS OF GUARANTOR, IN THE
POSSESSION OR CONTROL OF BANK FOR ANY PURPOSE.

         9. GUARANTOR WAIVES THE FILING OF A CLAIM WITH A COURT IN THE EVENT OF
RECEIVERSHIP OR BANKRUPTCY OF BORROWER, AND WAIVES EVERY DEFENSE, CAUSE OF
ACTION, COUNTERCLAIM OR SETOFF WHICH GUARANTOR MAY NOW HAVE OR HEREAFTER MAY
HAVE TO ANY ACTION BY BANK IN ENFORCING THIS GUARANTY, INCLUDING, WITHOUT
LIMITATION, EVERY DEFENSE, COUNTERCLAIM OR SETOFF WHICH GUARANTOR MAY NOW HAVE,
OR HEREAFTER MAY HAVE, AGAINST BORROWER OR ANY OTHER PARTY LIABLE TO BANK IN ANY
MANNER. GUARANTOR RATIFIES AND CONFIRMS WHATEVER BANK MAY DO PURSUANT TO THE
TERMS HEREOF AND WITH RESPECT TO ANY COLLATERAL FOR THE OBLIGATIONS, AND AGREES
THAT BANK SHALL NOT BE LIABLE FOR ANY ERROR IN JUDGMENT OR MISTAKES OF FACT OR
LAW. GUARANTOR HEREBY AGREES THAT IT MAY BE JOINED AS A PARTY DEFENDANT IN ANY
LEGAL PROCEEDING (INCLUDING, BUT NOT LIMITED TO, A FORECLOSURE PROCEEDING)
INSTITUTED BY BANK AGAINST BORROWER. GUARANTOR AND BANK IRREVOCABLY WAIVE THE
RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY SUCH LEGAL PROCEEDING IN WHICH
GUARANTOR AND BANK ARE ADVERSE PARTIES. THIS PROVISION IS A MATERIAL INDUCEMENT
TO BANK GRANTING BORROWER ANY FINANCIAL ACCOMMODATIONS AND ACCEPTING THIS
GUARANTY.



<PAGE>


         10. Repayment Claim. Should a claim be made upon Bank at any time for
repayment of any amount received by Bank in payment of the Obligations, or any
part thereof, whether received from Borrower, Guarantor pursuant hereto, or
otherwise from Borrower, or received by Bank as the proceeds of collateral, by
reason of: (1) any judgment, decree or order of any court or administrative body
having jurisdiction over Bank or any of its property, or (2) any settlement or
compromise of any such repayment claim effected by Bank, in its sole discretion,
with the claimant (including Borrower), Guarantor shall remain liable to Bank
for the amount so repaid to the same extent as if such amount had never
originally been received by Bank, notwithstanding any termination hereof or the
cancellation of any of the Notes or other instruments evidencing any of the
Obligations.

         TO INDUCE BANK TO GRANT FINANCIAL ACCOMMODATIONS TO BORROWER, GUARANTOR
IRREVOCABLY AGREES THAT ALL ACTIONS ARISING DIRECTLY OR INDIRECTLY AS A RESULT
OR IN CONSEQUENCE OF THIS GUARANTY, SHALL BE INSTITUTED AND LITIGATED ONLY IN
COURTS HAVING SITUS IN THE CITY OF CHICAGO, ILLINOIS, AND GUARANTOR HEREBY
CONSENTS TO THE EXCLUSIVE JURISDICTION AND VENUE OF ANY STATE OR FEDERAL COURT
LOCATED AND HAVING ITS SITUS IN SAID CITY, AND WAIVES ANY OBJECTION BASED ON
FORUM NONCONVENIENS, AND GUARANTOR HEREBY WAIVES PERSONAL SERVICE OF ANY AND ALL
PROCESS, AND CONSENT THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE BY CERTIFIED
MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO GUARANTOR AT THE ADDRESS INDICATED
IN THE INTRODUCTORY PARAGRAPH ABOVE OR IN BANK'S RECORDS IN THE MANNER PROVIDED
BY APPLICABLE STATUTE, LAW, RULE OF COURT OR OTHERWISE. FURTHERMORE, GUARANTOR
WAIVES ALL NOTICES AND DEMANDS IN CONNECTION WITH THE ENFORCEMENT OF BANK'S
RIGHTS HEREUNDER, AND HEREBY CONSENTS TO, AND WAIVES NOTICE OF THE RELEASE WITH
OR WITHOUT CONSIDERATION OF BORROWER OR ANY OTHER PERSON RESPONSIBLE FOR PAYMENT
OF THE OBLIGATIONS, OR OF ANY COLLATERAL THEREFOR.

         11. Governing Law. This Guaranty shall be governed by and construed in
accordance with the internal laws of the State of Illinois.

         12. Duration. This Guaranty shall remain and continue in effect
(notwithstanding the nonexistence at any time of any obligations of Borrower to
Bank) until: (i) Guarantor shall have received written notice of termination of
this Guaranty by Bank, (ii) all Obligations have been fully paid and (iii) all
commitments of Bank to lend money to Borrower have terminated.

         13. Successors and Assigns. This Guaranty shall be binding upon
Guarantor, and upon its successors and assigns.

         14. Integration. This Guaranty constitutes the entire agreement and
understanding between the Guarantor and the Bank with respect to the subject
matter hereof and supersedes all prior agreements, whether oral or written.
