        1.2 ASSUMPTION OF LIABILITIES. At the Closing, Purchaser shall assume
and agree to pay, perform and discharge Seller from the following liabilities of
Seller as existing on the Closing Date (the "ASSUMED LIABILITIES"):

          (a) All liabilities reflected in the balance sheet of Seller as of
     January 25, 1997, including, without limitation, those for product
     warranties and liabilities arising in the ordinary course of Seller's
     business which generally accepted accounting principles do not require to
     be reflected on the balance sheet dated January 25, 1997 and which do not
     exceed $10,000;

          (b) All of Seller's obligations under the "Assigned Contracts" as
     hereinafter defined;

          (c) All of Seller's liabilities as shown on the DISCLOSURE SCHEDULE
     hereto and made a part hereof; and

          (d) liabilities arising in the ordinary course of Seller's business
     after January 25, 1997, being the date of the most recent balance sheet,
     attached hereto as EXHIBIT A, included in the Financial Statements, as
     hereinafter defined, to the Closing together with any other liabilities not
     reflected on EXHIBIT A which other liabilities do not in the aggregate
     exceed $10,000.

     With respect to any Assumed Liability, such assumption by Purchaser is for
the benefit only of Seller and shall not expand, increase, broaden or enlarge
the rights or remedies of any other party, nor create in any other party any
right against Purchaser which such party would not have against Seller if this
Agreement had not been consummated.

     1.3 OTHER LIABILITIES NOT ASSUMED. Neither AMT nor Purchaser shall assume
any liabilities of Seller which are not described in SECTION 1.2 or set forth on
the DISCLOSURE SCHEDULE and, with respect to each Assumed Liability, neither AMT
nor Purchaser shall assume or be under any liability or obligation over and
above any amount, or after the occurrence of any limitation or expiration date,
of such liability or obligation stated on such schedule. Without limiting the
generality of the foregoing and except as otherwise provided on the DISCLOSURE
SCHEDULE or in SECTION 1.2 hereof, the Assumed Liabilities will not include, and
neither AMT nor Purchaser shall assume under this Agreement, any of the
following obligations or liabilities of Seller:

          (a) Except as otherwise provided in SECTION 4, any cost, expense,
     capital gain or income tax or any similar liability of Seller, any limited
     or general partner of the Seller (each, a "PARTNER" and collectively, the
     "PARTNERS") or any Partner arising from or growing out of the sale provided
     for by this Agreement.

          (b) Any debt, obligation or liability to any Partner, employee, agent,
     officer, director or security holder of Seller or of any entity owned or
     controlled in whole or in part by Seller under any employment, sales,
     representation or similar agreement not identified as an "Assigned
     Contract" (as defined below), or under any employee option plan, stock or
     securities purchase plan, bonus plan or arrangement, pension plan or other
     benefit plan, health plan or other employee welfare plan or arrangement.

                                        3


<PAGE>   8



          (c) Any obligations or amounts owed to any employees of Seller or any
     Partner.

          (d) Any debt, liability or obligation of Seller (or costs and expenses
     in connection therewith) to the extent that such debt, liability or
     obligation is actually satisfied or paid on behalf of Seller by an insurer
     or insurers under a policy issued to Seller.

          (e) Any liability or obligation arising from any violation by Seller
     or by its Partners, officers, employees or agents of any statute (or rule
     or regulation thereunder) or executive regulation of the United States or
     any State or any political subdivision or agency thereof or any statutes
     (or rule or regulation thereunder) or executive, administrative or
     quasi-judicial regulation of any foreign government.

          (f) Any liability or obligation whose existence violates or is
     contrary to any representation or warranty of Seller hereunder.

          (g) Any liability under any Environmental Law, as defined in EXHIBIT B
     hereto, connected in any manner with any products produced by, or events or
     activities produced by Seller prior to the Closing.

          (h) Federal or other domestic or foreign income tax or other tax
     liabilities known or unknown, existing or arising from operations prior to
     the Closing, except for taxes on products not delivered by Seller or paid
     for prior to the Closing.

          (i) Any liability or obligation for or arising under any claim for
     workers compensation or for any tort, breach of any legal duty, breach or
     violation of any contract or violation or breach of any law, statute,
     ordinance, rule, regulation, injunction or decree, or any liability or
     obligation for any "product liability" or other claim connected in any
     manner with any products, events or activities produced or taking place
     prior to the Closing.

          (j) Any liability to Trenwith Capital, Inc. ("TRENWITH"), arising
     under that certain letter agreement, dated June 25, 1996, by and between
     Trenwith and Seller, or otherwise.

     1.4 ASSIGNMENT OF CERTAIN CONTRACTS. At the Closing, Purchaser shall
succeed to the rights and privileges of Seller, and shall assume the obligations
of Seller performable after the Closing, pursuant to those leases, insurance
policies, contracts and other agreements, and only those leases, insurance
policies, contracts and other agreements, of Seller which are listed as
"Assigned Contracts" on the DISCLOSURE SCHEDULE hereto (the "ASSIGNED
CONTRACTS") as and in the form of the copies thereof (or, if oral, as and in the
form of the written statements of the terms thereof) furnished or made available
to Purchaser pursuant to SECTIONS 5.8, 5.9, 5.10, 5.11, 5.12 AND 5.18 hereto.
Without limiting the generality of the foregoing, neither AMT nor Purchaser
shall assume, nor shall either of them have any liability with respect to, any
obligations of Seller under any Assigned Contract (a) required therein to be
performed by Seller at or prior to the Closing or (b) arising out of any breach
thereof occurring prior to the Closing.

<PAGE>   9



     1.5 INSTRUMENTS OF CONVEYANCE, ASSUMPTION OR ASSIGNMENT. The sale,
conveyance, transfer, assignment and delivery of the Assets and the Assigned
Contracts and the assumption of the Assumed Liabilities, as herein provided,
shall be effected by bills of sale, endorsements, assignments, deeds, drafts,
checks, stock powers or other instruments in such reasonable and customary form
as shall be requested by AMT or Purchaser, and Seller shall at any time and from
time to time after the Closing, upon reasonable request, execute, acknowledge
and deliver such additional bills of sale, endorsements, assignments, deeds,
drafts, checks, stock powers or other instruments and take such other actions as
may be reasonably required to effectuate the transactions contemplated by this
Agreement.

2. PURCHASE PRICE
   --------------

     2.1 PURCHASE PRICE. In consideration for the sale, conveyance, transfer and
delivery of the Assets and the Assigned Contracts and upon the terms and subject
to the conditions set forth in this Agreement, Purchaser shall assume the
Assumed Liabilities and AMT shall pay to Seller the "PURCHASE PRICE," which
shall consist of:

          (a) a cash payment of $6,372,793;

          (b) two secured non-negotiable subordinated promissory notes of
     Purchaser, guaranteed by AMT, which notes are in substantially the form
     attached as EXHIBITS C-1 AND C-2 hereto (the "PURCHASE NOTES"), dated as of
     the Closing Date, in the aggregate original principal amounts (i) of
     $800,000 a copy of which is attached is EXHIBIT C-1 hereto (the "$800,000
     NOTE"), and (ii) $747,254 a copy of which is attached as EXHIBIT C-2
     hereto. The $800,000 Note shall be placed in escrow at or prior to the
     Closing, and the principal amount of the $800,000 Note shall be subject to
     adjustment to reflect decreases in Working Capital as described in SECTION
     2.2 hereof;

          (c) 179,492 shares of the common stock, $0.01 par value per share, of
     AMT ("AMT STOCK"), less 9,590 of such shares of AMT Stock which shall be
     placed in escrow at or prior to the Closing and which shall be subject to
     adjustment to reflect decreases in Working Capital as described in SECTION
     2.2; and

          (d) a non-negotiable promissory note in the original principal amount
     of $175,000 a copy of which is attached as EXHIBIT C-3 (the "$175,000
     NOTE").

     2.2 ADJUSTMENTS. For purposes of this Agreement, "WORKING CAPITAL" shall
mean current assets less current liabilities (excluding any reserve for doubtful
accounts) determined in accordance with generally accepted accounting principles
("GAAP") to the extent consistent with Seller's past practices. The Purchase
Price shall be adjusted downward to account for the amount, if any, by which
Working Capital of Seller as of the Closing is less than $150,000 (provided
that, for determining the amount of any such adjustment, such $150,000 amount
shall be increased by the amount by which $110,000 exceeds capital expenditures
made during January and February of 1997), as determined based on the "Working
Capital Audit," as hereinafter defined. Any adjustment to the Purchase Price
pursuant hereto shall be made by allocating 86.74% of such adjustment to the

                                        5


<PAGE>   10



principal amount of the Purchase Note and 13.26% of such adjustment to the
escrowed shares of AMT stock. Any amount by which Working Capital exceeds
$150,000 pursuant to the Working Capital Audit shall be used to immediately
prepay the principal amount outstanding on the $175,000 Note.

     2.3 ADJUSTMENT PROCEDURE. A post-Closing audit (the "WORKING CAPITAL
AUDIT") shall be completed by Purchaser's independent auditors and communicated
in writing to Seller no later than thirty days after the "Closing Date," as
hereinafter defined. If Seller disagrees with the result of the Working Capital
Audit, Seller shall inform Purchaser of such disagreement in writing within ten
business days after results of the Working Capital Audit are communicated to
Seller. Purchaser and Seller shall attempt to resolve their differences through
good faith negotiation. If Purchaser and Seller are unable to resolve such
disagreement within twenty days after Seller informs Purchaser of its
disagreement with the results of the Working Capital Audit, the disagreement
will be submitted to a binding third-party audit, with costs to be shared
equally by Purchaser and Seller. Such audit shall be conducted in San Diego,
California by an auditor who (a) shall be selected by the then current managing
partner of the San Diego office of a so-called "Big Six" accounting firm agreed
upon by AMT and Seller and (b) shall possess a minimum of 10 years' experience
in accounting and auditing.

5. REPRESENTATIONS AND WARRANTIES OF SELLER
   ----------------------------------------

     Seller represents, warrants, covenants and agrees that, except as set forth
in the DISCLOSURE SCHEDULE:

     5.1 ORGANIZATION AND POWER. Seller is a limited partnership duly organized,
validly existing and in good standing under the laws of the State of Delaware
and is duly qualified and in good standing in each other jurisdiction in which
it owns or leases properties, conducts operations or maintains a stock of goods
and where the failure to so qualify would have a material adverse effect on
Seller or its business or property (a true and correct list of each such
jurisdiction is set forth in the DISCLOSURE SCHEDULE), with full partnership
power and authority to carry on the business in which it is engaged and to
execute and deliver and carry out the transactions contemplated by this
Agreement. GEC is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware.

     5.2 DUE AUTHORIZATION; EFFECT OF TRANSACTION. No provision of Seller's
Certificate of Limited Partnership or Fourth Amended and Restated Limited
Partnership Agreement or of any agreement, instrument or understanding, or any
judgment, decree, rule or regulation, to which Seller is a party or by which
Seller is bound, has been or will be violated by the execution and delivery by
Seller of this Agreement or the performance or satisfaction of any agreement or
condition herein contained upon Seller's part to be performed or satisfied, and
all requisite partnership and other authorizations for such execution, delivery,
performance and satisfaction by Seller have been duly obtained. This Agreement
will, upon execution and delivery, be a legal, valid and binding obligation of
Seller, enforceable in accordance with its terms.

     5.3 FINANCIAL STATEMENTS. Seller has delivered to Purchaser true, correct
and complete copies of the audited financial statements of Seller, including the
balance sheet of Seller as at the close of its fiscal year ended December 31,
1996, a related statement of operations, consolidated statement of changes in
partners' equity, and statement of cash flows for the year then ended (the
"AUDITED FINANCIAL STATEMENTS"). Seller has also delivered to Purchaser the
balance sheet of Seller as at January 25, 1997, together with related statement
of operations, consolidated statement of changes in partners' equity, and
statement of cash flows for the period then ended (the "INTERIM FINANCIAL
STATEMENTS").

     The Audited Financial Statements, including the notes to such financial
statements, and the Interim Financial Statements are hereinafter sometimes
collectively referred to as the "FINANCIAL STATEMENTS." All of the Financial
Statements have been prepared in accordance with GAAP consistently followed
throughout the periods (except as set forth in such notes or statements and,
with respect to the Interim Financial Statements, except for normal auditing
adjustments) and fairly present, in all material respects, the financial
condition of Seller and the results of its operations as at the dates thereof
and for the periods covered thereby. To Seller's knowledge and except as set
forth in the DISCLOSURE SCHEDULE, the Financial Statements reflect or provide
for all material claims against, and all debts and liabilities of, Seller, fixed
or contingent, as at the dates thereof, and to Seller's knowledge there has not
been any change between the date of the most recent Financial

                                        7


<PAGE>   12



Statements and the date of this Agreement which has affected materially and
adversely the business or properties or condition or prospects, financial or
other, or results of operations of Seller.

     5.4 ACCOUNTS RECEIVABLE. All customer and trade notes and accounts
receivable (collectively, "ACCOUNTS RECEIVABLE") owned by Seller on the date of
the most recent balance sheet included in the Financial Statements, net of
reserves, are in the aggregate fully collectible in the ordinary course of
business consistent with the past practices of Seller within 120 days of the
Closing, to the extent of the aggregate face value thereof as indicated on such
balance sheet. Purchaser shall attempt to collect all Accounts Receivable in a
manner consistent with Seller's past practices. At the option of the Purchaser
exercisable within ten days after the end of the 120 day period set forth in the
previous sentence, any such Accounts Receivable remaining uncollected 120 days
after the Closing together with supporting documentation may be returned to
Seller for a cash payment in the amount of such Accounts Receivable, and Seller
may thereafter collect such Accounts Receivable in a manner consistent with
Seller's past practices. To the extent that, after the Closing and prior to the
return of receivables to Seller, Purchaser receives payment from customers,
whose receivables Purchaser decides to return to Seller in accordance with this
section, such payments shall be applied to such customer's oldest receivables
first.

     5.5 DISTRIBUTIONS. From January 25, 1997 to the date hereof, Seller has not
declared or made any distribution whatsoever to any holder of its securities,
either in cash, securities, or other property, through purchases or redemptions
of securities or otherwise.

     5.6 SUBSIDIARIES. Except for the GEC Stock, Seller does not own, directly
or indirectly, any of the capital stock of any corporation, association, trust
or similar entity, any interest in the equity of any partnership or similar
entity, any share in any joint venture, or any other equity or proprietary
interest in any entity or enterprise, however organized and however such
interest may be denominated or evidenced.

     5.7 REAL PROPERTY. Seller owns no real property.
         -------------

     5.8 LEASES. The leases listed and described in the DISCLOSURE SCHEDULE and
constituting a portion of the Assigned Contracts constitute all the leases of
real or material items of personal property under which Seller is bound or to
which Seller is a party. Each lease listed in the DISCLOSURE SCHEDULE is valid,
binding, subsisting and enforceable in accordance with its terms, and neither
Seller nor, to the knowledge of Seller, any landlord or lessor is in default or
in arrears in the performance or satisfaction of any agreement or condition on
its part to be performed or satisfied thereunder, and no written waiver or
indulgence or, to the knowledge of Seller, oral or other waiver or indulgence
has been granted by any of the landlords or lessors under said leases. Seller is
not the landlord or lessor under any leases of real or personal property.

     5.9 PERSONAL PROPERTIES. Seller directly or indirectly through GEC owns and
has good title to all the tangible and intangible personal property and assets,
other than the leaseholds or licenses referred to in the DISCLOSURE SCHEDULE,
reflected upon the most recent balance sheet included in the Financial
Statements or used by Seller in its business if not so reflected, free and clear
of all liens, encumbrances and security interests of other persons, of whatever
kind and character, except as set

                                        8


<PAGE>   13



forth in the DISCLOSURE SCHEDULE. The DISCLOSURE SCHEDULE contains an
identification of each item of fixed assets and machinery and equipment on the
books of Seller and GEC. None of the fixed assets and machinery and equipment is
subject to contracts of sale, none is held by Seller directly or indirectly
through GEC as lessee or as conditional sales vendee under any lease or
conditional sales contract and none is subject to any title retention agreement,
except as set forth in the DISCLOSURE SCHEDULE. The production machinery and
equipment currently in use on a regular basis has been maintained in a manner
consistent with Seller's past practice and, to the knowledge of Seller, does
not, and as of the Closing will not, require repairs exceeding a cost of $5,000
with respect to any single such piece of machinery or equipment or $25,000 in
the aggregate. All of Seller's or GEC's inventories of finished goods,
work-in-process, raw materials, and other miscellaneous supplies and materials
("INVENTORY"), are capable of being sold by Seller in the ordinary course of
business at a price equal to the valuation of Inventory in the most recent
balance sheet (net of reserves) included in the Financial Statements.

     5.10 EMPLOYMENT ARRANGEMENTS. Except as set forth on the DISCLOSURE
SCHEDULE, Seller has no obligation, contingent or otherwise, under any
employment agreement, collective bargaining or other labor agreement, any
agreement containing severance or termination pay arrangements, deferred
compensation agreement, retainer or consulting arrangements, pension or
retirement plan, bonus or profit-sharing plan, employee stock option or purchase
plan or other employee contract or non- terminable (whether with or without
penalty) arrangement, group life, health, medical or hospitalization insurance,
plan or program or other employee or fringe benefit plan, including vacation
plans or programs and sick leave plans or programs. The DISCLOSURE SCHEDULE sets
forth the basis of funding, and the current status of, any past service
liability with respect to any such plan or agreement. Seller or its employees
are not now and for the past five years have not been subject to or involved in
or, to Seller's knowledge, threatened with any union elections, petitions
therefor or other organizational activities. Seller has performed all material
obligations required to be performed under all such agreements, plans and
arrangements and is not in breach of or in default or arrears under the terms
thereof.

     5.11 MATERIAL CONTRACTS AND ARRANGEMENTS. Except as set forth in the
DISCLOSURE SCHEDULE or reflected in the Financial Statements, Seller has no
contract or arrangement, including, without limitation, any commitments or
obligations, contingent or otherwise, under any contract or arrangement (a) for
the purchase or sale of inventory in excess of $5000 in any one instance, (b)
for the purchase or sale of supplies, services or other items in excess of $5000
in any one instance, (c) for the purchase, sale or lease of any equipment or
machinery, (d) for the performance of service for others in excess of $5000 in
any one instances or (e) extending beyond June 30, 1997. Each of such contracts
and arrangements is valid, binding, subsisting and enforceable against Seller in
accordance with its terms and Seller has performed all material obligations
required to be performed by it under any such contract or arrangement and is not
in breach or default or in arrears in any material respect or in any other
respect which would permit the other party to cancel such contract or
arrangement under the terms thereof.

     5.12 CARBON FIBER SUPPLY ARRANGEMENTS. The DISCLOSURE SCHEDULE describes
all of Seller's existing executory supply contracts, agreements and other
arrangements with Toray Industries, Inc. for the supply of carbon fiber and
carbon epoxy prepreg.

                                        9


<PAGE>   14



     5.13 ORDINARY COURSE OF BUSINESS. Seller, from the date of the most recent
Financial Statements, to the date hereof,

          (a) has operated its business in the normal, usual and customary
     manner in the ordinary and regular course of its business;

          (b) has not sold or otherwise disposed of any of its properties or
     assets, other than inventory sold in the ordinary course of business;

          (c) has not sold, assigned or transferred any patents, trademarks,
     trade names, trade secrets, copyrights or other intangible assets;

          (d) has not increased the compensation payable or to become payable to
     any of its officers, employees, or agents paid at a rate exceeding $50,000
     annually following such increase;

          (e) has not suffered any material damage, destruction or loss (whether
     or not covered by insurance) or any acquisition or taking of property by
     any governmental authority;

          (f) has not knowingly waived any rights which individually or in the
     aggregate exceed $5000; and

          (g) has not experienced any organized, collective work stoppage or
     industrial action.

     5.14 LITIGATION AND COMPLIANCE WITH LAWS. There is no litigation pending to
which Seller is a party or which concerns any Asset and, to Seller's knowledge,
no such litigation is threatened. Seller is and at all times since its inception
has been in all material respects in compliance with all laws and governmental
rules and regulations, domestic and foreign, and all requirements of insurance
carriers, applicable to its business or affairs or properties or assets,
including, without limitation, those relating to pollution, pollution of public
health, the environment and occupational health and safety.

     5.15 TAXES. "TAXES" means any and all federal, state, local, or foreign
income, gross receipts, license, payroll, employment, excise, severance, stamp,
occupation, premium, windfall profits, environmental (including taxes under
Internal Revenue Code section 59A), customs duties, capital stock, franchise,
profits, withholding, social security (or similar), unemployment, disability,
real property, personal property, sales, use, transfer, registration, value
added, alternative or add-on minimum, estimated, or other tax of any kind
whatsoever, including any interest, penalty, or addition thereto, whether
disputed or not.

     Seller has filed or caused to be filed, or on the date of the Closing will
have filed, all returns, declarations and reports related to Taxes that are
required to be filed by Seller on or prior to the Closing. All Taxes due and
payable by Seller on or before the date of this Agreement with respect to the
Assets have been paid except for any such obligations being contested in good
faith and which are described on the DISCLOSURE SCHEDULE. Seller has not
received any notice or assessment to the

                                       10


<PAGE>   15



effect that there are Taxes due or claimed to be due from Seller. In addition,
to the knowledge of Seller, no such notice is contemplated or under
consideration. Seller has no knowledge nor has Seller received any notice of the
assertion or threatened assertion of any lien on any of the Assets on account of
any unpaid Taxes that are due and payable. No audits of the returns or reports
of Seller by any government authority are pending or, to the knowledge of
Seller, threatened. From January 25, 1997 to the date hereof Seller has not made
any payment of or on account of any federal, state or local income, franchise or
any real or personal property taxes, except as set forth in the DISCLOSURE
SCHEDULE. Seller is not aware of any basis upon which any assessment for a
material amount of additional federal income taxes could be made. The
information shown on the federal income tax returns of Seller heretofore
delivered to AMT fairly presents the information purported to be shown, in all
material respects.

     5.16 ENVIRONMENTAL MATTERS. Without limiting the generality of
 SECTION 5.14:

          (a) Seller is in compliance in all material respects with all
     applicable Environmental Laws (as such term is defined in EXHIBIT B
     hereto);

          (b) Seller has obtained all permits and approvals required under
     Environmental Laws, including, without limitation, all environmental,
     health and safety permits, licenses, approvals, authorizations, variances,
     agreements and waivers of federal, state and local governmental authorities
     ("PERMITS") necessary for the conduct of Seller's business and the
     operation of its facilities, and all such Permits are in full force and
     effect and Seller is in all material respects in compliance with all terms
     and conditions of such Permits;

          (c) To the knowledge of Seller, neither Seller nor any of its
     currently or previously owned or leased property or operations has been
     named as a potentially responsible party or is subject to any outstanding
     written order from or agreement with any federal, state or local
     governmental authority or other person or is subject to any judicial or
     docketed administrative proceeding respecting (i) Environmental Laws, (ii)
     Remedial Action (as such term is defined in EXHIBIT B hereto) or (iii) any
     material Environmental Liabilities and Costs (as such term is defined in
     EXHIBIT B hereto);

          (d) Seller has not received any notice or claim to the effect that it
     is or is reasonably expected to be subject to a demand or claim by any
     person as a result of a Release (as such term is defined in EXHIBIT B
     hereto) or threatened Release or any notice letter or request for
     information under CERCLA (as such term is defined in EXHIBIT B hereto); and

          (e) No Environmental Lien (as such term is defined in EXHIBIT B
     hereto) and no unrecorded Environmental Lien of which Seller has notice has
     attached to any property of Seller.

     5.17 TRADEMARKS, LICENSES, ETC. The DISCLOSURE SCHEDULE sets forth all of
the trademarks, trade names, service marks, patents, copyrights, registrations
or applications with respect thereto, and licenses or rights under the same
owned, used or intended to be acquired or used by Seller, and, to the extent
indicated in the DISCLOSURE SCHEDULE, the same have been duly registered in such
offices

                                       11


<PAGE>   16



as are indicated therein. Seller is the sole and exclusive owner of the
trademarks, trade names, service marks and copyrights, the holder of the full
record title to the trademark registrations and the sole owner of the inventions
covered by the patents and patent applications, all as set forth in the
DISCLOSURE SCHEDULE; Seller has the sole and exclusive right, except as set
forth in the DISCLOSURE SCHEDULE, to use such trademarks, trade names, service
marks, patents and copyrights. Seller's use of such trademarks, trade names,
service marks, patents and copyrights has not infringed, and is presently not
infringing, the rights of any person and, to Seller's knowledge, no person is
currently infringing any of Seller's rights therein.

     5.18 INSURANCE. The insurance policies listed and described briefly (which
description sets forth deductible amounts, if any) in the DISCLOSURE SCHEDULE
constitute all of the policies in force and effect in respect of the business,
properties and assets, including, without limitation, insurance on personnel, of
Seller. Seller is not in default under any such policy.

     5.19 EXTRAORDINARY EVENTS. From January 25, 1997 to the date hereof, none
of the business or properties or condition, financial or other, or results of
operations of Seller have been materially and adversely affected in any way as
the result of any fire, explosion, accident, casualty, labor disturbance,
requisition or taking of property by any governmental body or agency, flood,
embargo, or Act of God or the public enemy, or cessation, interruption or
diminution of operations, whether or not covered by insurance.

     5.20 [Intentionally omitted.]

     5.21 PRODUCTS IN WARRANTY. Attached as part of the DISCLOSURE SCHEDULE are
true and correct copies of Seller's standard warranty agreements used by Seller
in connection with its business operations. Seller's standard warranty
agreements apply to each product in warranty except as otherwise indicated on
the DISCLOSURE SCHEDULE. Seller is not in violation in any material respect of
any such warranty agreement.

     5.22 CERTAIN TRANSACTIONS. None of the Partners, officers, directors or
employees of Seller or the General Partner is presently a party to any
transaction with Seller (other than for services as officers, directors and
employees), including, without limitation, any contract, agreement or other
arrangement providing for the furnishing of services to or by, providing for
rental of real or personal property to or from, or otherwise requiring payments
to or from, any such Partner, officer, director or employee, any member of a
family of any such Partner, officer, director or employee or any corporation,
partnership, trust or other entity in which any such Partner, officer, director
or any employee has a substantial interest or is an officer, director, trustee
or partner.

     5.23 NO GOVERNMENTAL AUTHORIZATIONS OR APPROVALS REQUIRED. No authorization
or approval of, or filing with, any governmental agency, authority or other
regulatory body will be required of Seller in connection with the execution and
delivery of this Agreement or the consummation of the transactions contemplated
hereby.

     5.24 EMPLOYEE BENEFIT PLANS. The DISCLOSURE SCHEDULE contains a true,
correct and complete list of all pension, profit sharing, retirement, deferred
compensation, welfare, insurance disability,

                                       12


<PAGE>   17



bonus, vacation pay, severance pay and other similar plans, programs or
agreements, and every material personnel policy, whether reduced to writing or
not, relating to any persons employed by Seller and maintained at any time by
Seller or the General Partner or by any other member (hereinafter, "AFFILIATE")
of a controlled group of corporations, group of trades or businesses under
common control or affiliated service group that includes Seller or the General
Partner (as defined for purposes of Section 414(b), (c) and (m) of the Code)
(collectively, the "PLANS"). Seller has made available to Purchaser true,
correct and complete copies of all Plans that have been reduced to writing,
together with all documents establishing or constituting any related trust,
annuity contract, insurance contract or other funding instrument, and true,
correct, and complete written summaries of those that have not been reduced to
writing. Except as set forth on the DISCLOSURE SCHEDULE, neither Seller nor the
General Partner nor any Affiliate has any obligation or other employee benefit
plan liability under applicable law; nor has Seller, the General Partner or any
Affiliate ever been obligated to contribute to any "multi-employer plan," as
defined in Section 3(37) of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"). Neither Seller nor the General Partner nor any Affiliate
has incurred any "withdrawal liability" calculated under Section 4211 of ERISA
and there has been no event or circumstance which would cause them to incur any
such liability. Neither Seller nor the General Partner nor any Affiliate has
ever maintained a Plan providing health or life insurance benefits to former
employees. No Plan previously maintained by Seller, the General Partner or any
Affiliate that was subject to ERISA has been terminated; no proceedings to
terminate any such Plan have been instituted within the meaning of Subtitle C of
Title IV of ERISA; and no reportable event within the meaning of Section 4043 of
said Subtitle C has occurred with respect to any such Plan, and no liability to
the Pension Benefit Guaranty Corporation has been incurred. For each Plan,
Seller, the General Partner and every Affiliate are, in all material respects,
in compliance with all requirements prescribed by all statutes, regulations,
orders, or rules currently in effect, and they have in all material respects
performed all obligations required to be performed by them. Neither Seller nor
the General Partner nor any Affiliate, nor any of their Partners, directors,
officers, employees, or agents, nor any trustee or administrator of any trust
created under the Plans, have engaged in or been a party to any "prohibited
transaction" as defined in Section 4975 of the Code and Section 406 of ERISA
that could subject AMT or Purchaser or their affiliates, directors, or employees
or the Plans or the trusts relating thereto or any party dealing with any of the
Plans or trusts to any tax or penalty on "prohibited transactions" imposed by
Section 4975 of the Code.

     Each Plan intended to qualify under Section 401(a) of the Code has been
determined by the Internal Revenue Service to so qualify, and the trusts created
thereunder have been determined to be exempt from tax under Section 501(a) of
the Code; copies of all determination letters have been delivered to Purchaser;
and nothing has occurred since the date of such determination letters that might
cause the loss of such qualification or exemption. There are no qualified profit
sharing or stock bonus plans, all employer contributions accrued for plan years
ending prior to the Closing Date under the Plan terms and applicable law have
been made.

     Except as set forth on the DISCLOSURE SCHEDULE, all of the liabilities with
respect to all of the Plans are accurately reflected in the Financial Statements
or incurred thereafter only in the ordinary course of Seller's business, none of
which are material.

and hold AMT and Purchaser, or any subsidiary of AMT or Purchaser holding title
to any Asset (collectively, the "INDEMNIFIED PERSONS"), harmless from and
against the amount of any actual (or potential in the case of any litigation or
claims by any person not a party to this Agreement) damage, loss, cost or
expense (including reasonable attorneys' fees and settlement costs) to the
Indemnified Persons ("LOSS") occasioned or caused by, resulting from or arising
out of:

          (a) any failure by Seller to perform, abide by or fulfill any of the
     agreements, covenants or obligations set forth in this Agreement to be so
     performed or fulfilled by Seller;

          (b) any material breach of any of the representations or warranties of
     Seller set forth in this Agreement;

          (c) any claim, known or unknown, arising out of or by virtue of or
     based upon any liability or obligation of Seller which is not an Assumed
     Liability including, without limitation, any fees or commissions owed to
     Trenwith, amounts owed by Seller under the California Bulk Sales Law or
     amounts owed by Seller to any taxing authority (other than such amounts
     owed to taxing authorities which are Assumed Liabilities);

PROVIDED, HOWEVER, THAT Loss shall not include any incidental, consequential,
punitive damages, or any amount to the extent that such amount is either an
Assumed Liability or reflected in the working capital adjustment in accordance
with SECTION 2.2 but only to the extent that such adjustment results in a
reduction in the Purchase Price. All claims for indemnification shall be
submitted in writing within 24 months of the Closing Date.

     The amount of any Loss shall be the amount of cash reimbursement that, when
received by the Indemnified Person incurring such loss, shall reimburse such
Indemnified Person for any cost or expense actually incurred by reason of the
Loss.

     11.2 LIMITS ON INDEMNIFICATION BY SELLER
          -----------------------------------

          (a) Subject to SECTION 11.2(d) below, Purchaser's and AMT's sole
     recourse and remedy shall be to indemnification hereunder. The obligation
     of Seller to indemnify the Indemnified Persons hereunder shall not exceed
     in the aggregate $1,250,000, after accounting for taxes in accordance with
     SECTION 11.2(c).

          (b) Subject to SECTION 11.2(d) below, the Seller shall not be liable
     and the Indemnified Persons shall have no right to indemnification until,
     and then only to the extent that, the aggregate amount of losses exceeds
     $100,000 after accounting for taxes in accordance with SECTION 11.2(c)
     below; provided that no single item of loss shall exceed $25,000 not to
     exceed the limitations set forth in this SECTION 11.2. With respect to each
     single item of loss that exceeds $25,000, the Indemnified Persons shall be

<PAGE>   25



          (c) For purposes of this SECTION 11.2(c):

               (i) the term "ACTUAL TAX LIABILITY" shall mean, for any given
          fiscal year, the dollar amount, if any, of the federal income tax paid
          by Purchaser as reflected on Purchaser's consolidated federal income
          tax return for such fiscal year; and

               (ii) the term "EFFECTIVE TAX RATE" shall mean, for any given
          fiscal year, Purchaser's Actual Tax Liability divided by Purchaser's
          net income before taxes as reported on Purchaser's federal income tax
          return.

          The amount of any Loss hereunder shall be reduced by the amount, if
     any, by which such Loss reduces Purchaser's Actual Tax Liability for the
     fiscal year in which such Loss was accrued in accordance with GAAP. The
     amount of such reduction, if any, shall be calculated by multiplying the
     amount of the Loss by the Effective Tax Rate for that year.

          (d) if Purchaser or AMT shall suffer any Loss (including the costs of
     defense) arising out of or in connection with any matter described in
     SECTIONS 11.1(a) OR (c) AMT and/or Purchaser shall be entitled to full
     recourse and indemnification without reference to the limitations set forth
     in SECTIONS 11.2(a) AND (b) above.

     11.3 INDEMNIFICATION BY PURCHASER. Purchaser hereby agrees to indemnify,
defend and hold Seller harmless from and against the amount of any actual (or
potential in the case of any litigation or claims by any person not a party to
this Agreement) damage, loss, cost or expense (including reasonable attorneys'
fees and settlement costs) to Seller ("LOSS") occasioned or caused by, resulting
from or arising out of:

          (a) any failure by Purchaser or AMT to perform, abide by or fulfill
     any of the agreements, covenants or obligations set forth in or entered
     into in connection with this Agreement to be so performed or fulfilled by
     Purchaser or AMT;

          (b) any material breach of any of the representations or warranties of
     Purchaser or AMT set forth in this Agreement; or

          (c) any claim, known or unknown, arising out of or by virtue of or
     based upon any liability or obligation which is an Assumed Liability;

PROVIDED, HOWEVER, THAT Loss shall not include incidental, consequential or
punitive damages.

     Except as otherwise provided for in SECTION 7.6 all claims for
indemnification shall be submitted in writing within 24 months of the Closing
Date.

     The amount of any Loss shall be the amount of cash reimbursement that, when
received by Seller incurring such loss, shall reimburse Seller for any costs or
expenses actually incurred by reason of the Loss.

<PAGE>   26



     11.4 NOTICE OF CLAIM. Seller, AMT or Purchaser, as in the case may be
("CLAIMANT") shall give prompt written notice to Seller, AMT or Purchaser as
appropriate ("INDEMNIFYING PARTY") of any claim (actual or threatened) or other
event which in the judgment of Claimant might result or has resulted in a Loss
by Claimant hereunder, and Indemnifying Party shall have the right to assume the
defense of such claim or any litigation resulting therefrom; PROVIDED THAT (a)
Indemnifying Party confirms in writing its obligation to provide indemnification
with respect to such claim, and (b) counsel for Indemnifying Party, who shall
conduct the defense of such claim (actual, threatened or asserted) or
litigation, shall be reasonably satisfactory to the Claimant, and Claimant may
participate in such defense at its expense, and provided, further, that the
omission by Claimant to give notice as provided herein shall not relieve
Indemnifying Party of its obligations hereunder except to the extent that such
omission results in a failure of actual notice to Indemnifying Party and
Indemnifying Party is damaged or prejudiced as a result of such failure of
actual notice. Indemnifying Party, in the defense of any such claim or
litigation, shall not, except with the consent of Claimant, consent to the entry
of any judgment or decree or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to the
Claimant of a release from all liability in respect to such claim or litigation
(provided that if Claimant does not so consent then any loss in excess of the
proposed settlement shall be paid by Claimant), and Indemnifying Party shall
have no liability with respect to any payment made by Claimant in connection
with the settlement, satisfaction or compromise of any claim unless Indemnifying
Party shall have approved thereof in advance in writing. If Claimant shall not
have received notice that Indemnifying Party shall assume the defense of such
claim within twenty (20) days after the notice is sent to Indemnifying Party of
the existence of such claim, then Claimant shall be free to proceed with the
defense of such claim at the expense of Indemnifying Party. In such case,
Indemnifying Party shall pay all expenses of defense promptly, and in any event
within five (5) days of submission of any invoice or bill for such expenses to
Indemnifying Party. Each such notice shall be accompanied (or followed as
promptly as is reasonably practicable after the amount of such Loss becomes
determinable) by a certificate signed by the President of Claimant, and setting
forth in reasonable detail the calculation of the amount of such Loss in
accordance with the provisions hereof, and accompanied by copies of all relevant
documents and records. The omission to give such notice or provide such
certificate by Claimant shall not relieve Indemnifying Party of its obligations
under this SECTION 11.4 except to the extent such omission results in a failure
of actual notice to Indemnifying Party and Indemnifying Party is damaged or
prejudiced by such failure of actual notice. No Loss shall be considered to have
occurred with respect to any payment made by Claimant in settlement,
satisfaction or compromise of any claim unless Indemnifying Party shall have
approved thereof in advance and in writing.

     11.5 INDEMNITY ESCROW. In order to provide AMT and Purchaser with
assurances that there will be sufficient funds available to meet its indemnity
obligations hereunder, Seller shall escrow $1,500,000 for a period of 12 months
from the date hereof after which $250,000 shall be released and the remaining
$1,250,000 shall remain in escrow for a further 12 months, in accordance with
the provisions of the Escrow Agreement attached as EXHIBIT I hereto (the "ESCROW
AGREEMENT"). Such escrowed funds shall be used solely for the purpose of making
payments to Indemnified Persons pursuant to this SECTION 11.

contemplated hereby, neither AMT or Purchaser nor Seller has taken any steps to
comply with the California Bulk Sales Law. Notwithstanding the foregoing, Seller
covenants and agrees to pay and discharge promptly and when due, and in all
respects to defend AMT and Purchaser against, all claims of creditors (other
than Assumed Liabilities) that are asserted against AMT or Purchaser by reason
of noncompliance with said Bulk Sales Law.

13. BROKERAGE FEE
    -------------

     The parties hereto severally represent that no broker (other than Trenwith)
has been involved in this transaction and each party agrees to indemnify and
hold the others harmless from payment of any brokerage fee, finders fee or
commission claimed by any party who claims to have been involved because of
association with such party; PROVIDED THAT Seller (pursuant to an agreement
between Seller and Trenwith) shall be responsible for payment of any fees owed
to Trenwith in connection with this transaction at the Closing.

14. ENTIRE AGREEMENT; AMENDMENTS; WAIVERS
    -------------------------------------

     This Agreement constitutes the entire agreement of the parties related to
the subject matter of this Agreement, supersedes all prior or contemporary
agreements, representations, warranties, covenants and understandings of the
parties. This Agreement may not be amended, nor shall any waiver, change,
modification, consent or discharge be effected, except by an instrument in
writing executed by or on behalf of the party against whom enforcement of any
amendment, waiver, change, modification, consent or discharge is sought. In
furtherance of the foregoing, the parties hereto acknowledge that (a) there have
been no representations, warranties, covenants, understandings or agreements
related to the subject matter of this Agreement other than as set forth herein
and therefore no reliance can be placed on matters other than as set forth
herein, and (b) no agent of any party has or had authority to make
representation, warranties, covenants or agreements on behalf of such party and
if and to the extent so made, such representations, warranties, covenants or
agreements were not authorized and have not been the subject upon which reliance
has been placed.

     Any waiver of any term or condition of this Agreement, or of the breach of
any covenant, representation or warranty contained herein, in any one instance,
shall not operate as or be deemed to be or construed as a further or continuing
waiver of such term, condition or breach of covenant, representation or
warranty, nor shall any failure at any time or times to enforce or require
performance of any provision hereof operate as a waiver of or affect in any
manner such party's right at a later time to enforce or require performance of
such provision or of any other provision hereof; and no such written waiver,
unless it, by its own terms, explicitly provides to the contrary, shall be
construed to effect a continuing waiver of the provision being waived and no
such waiver in any instance shall constitute a waiver in any other instance or
for any other purpose or impair the right of the party against whom such waiver
is claimed in all other instances or for all other purposes to require full
compliance with such provision.

written consent of the others. This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors and

    ------------

     If any provision or provisions of this Agreement shall be, or be found to
be, invalid, inoperative or unenforceable as applied to any particular case in
any jurisdiction or jurisdictions, or in all jurisdictions or in all cases,
because of the conflict of any provision with any constitution or statute or
rule of public policy or for any other reason, such circumstance shall not have
the effect of rendering the provision or provisions in question invalid,
inoperative or unenforceable in any other jurisdiction or in any other case or
circumstance or of rendering any other provision or provisions herein contained
invalid, inoperative or unenforceable to the extent that such other provisions
are not themselves actually in conflict with such constitution, statute or rule
of public policy, but this Agreement shall be reformed and construed in any such
jurisdiction or case as if such invalid, inoperative or unenforceable provision
had never been contained herein and such provision reformed so that it would be
valid, operative and enforceable to the maximum extent permitted in such
jurisdiction or in such case.

17. TERMINATION
    -----------

     This Agreement may be terminated at any time prior to the Closing without

Seller and AMT. Each of Seller and AMT may extend the Closing Date, in each case
on no more than two occasions, and in each case for a seven-day period, by
either of AMT or Seller giving written notice to the other of such seven-day
extension. Thereafter, this Agreement may be terminated by written notice by
either Seller or AMT if each of the agreements contemplated by this Agreement
have not been executed and delivered and the Closing has not occurred on or
before such extended Closing Date; provided that the failure to close shall not
have occurred as a result of the terminating party's failure to either (a)
fulfill all of its obligations under this Agreement, or (b) take any actions
reasonably required to be taken by it to fulfill the other party's conditions to
closing, as set forth in SECTIONS 9 AND 10 respectively.
