<PAGE>   10
Assets in Sections 1.1(c), (d), (e), (k), (p), (t), (u), (v) and (w) above does
not imply a representation or warranty that Seller necessarily owns all of the
items included in such global descriptions.

       1.2  Excluded Assets.  Notwithstanding any provision contained in this
Agreement to the contrary, the following assets and properties of Seller shall
be excluded from the Assets to be transferred to Buyer hereunder:

              (a)  the assets and properties of Seller described on Schedule

       agreements not assumed by Buyer pursuant to Section 1.7; and

              (f)  all rights of Seller under or pursuant to this Agreement.

       1.3  Instruments of Conveyance.  In order to effectuate the transfer of
the Assets contemplated by Section 1.1, at the Closing, Seller shall execute
and deliver, or cause to be executed and delivered, to Buyer, dated the Closing

certificates of title, and other documents or instruments of assignment,
transfer, or conveyance as Buyer shall reasonably deem necessary or appropriate
to vest in or confirm to Buyer good and indefeasible title to the Assets, free
and clear of all Encumbrances other than the Permitted Encumbrances.

       1.4  Purchase Price and Payment.  In consideration of the transfer by
Seller to Buyer of the Assets, in addition to the assumption of the Assumed
Liabilities, and subject to adjustment pursuant to Section 1.5 below, at the
Closing Buyer shall pay to Seller the aggregate purchase price of Five Million
Two Hundred Seventy Thousand Six Hundred Twelve Dollars ($5,270,612.00) (the
"Purchase Price").  The Purchase Price shall be paid by (a) Buyer's payment to
Seller of Two Million Six Hundred Thirty-Five Thousand Three Hundred Six
Dollars ($2,635,306.00) in cash in immediately available funds by confirmed
wire transfer to a bank account to be designated by Seller (such designation to
occur no later than the third business day prior to the Closing Date) (such
payment, the "Cash Portion of the Purchase Price"), and (b) Buyer's delivery to
Seller of shares of Buyer's Common Stock, par value $0.01 per share, the number
of which shares (the "Buyer Shares") to be equal to $2,635,306.00 divided by

                                      -5-
<PAGE>   11
share.  In the event the foregoing formula would result in the issuance of a
fractional share of Common Stock to Seller, Buyer shall pay Seller cash at the
Closing in lieu of such fractional share.

       1.5 Adjustment of Purchase Price.

              (a) The Purchase Price to be paid at Closing under Section 1.4
       (before adjustment) is based in part on the aggregate balance reported
       on Schedule 1.5(a) (the "Pre-Closing Statement") which represents the
       net working capital, debt and equipment of Seller for the purposes of
       this agreement ("Net Working Capital, Debt and Equipment").  The amounts
       reflected in Schedule 1.5(a) are (i) the agreed upon value of equipment
       of the Seller as of April 24, 1998; (ii) the agreed upon value of parts
       inventory of the Seller as of December 31, 1997; and (iii) Seller's good
       faith estimate of the accounts receivable, certain accrued expenses and
       liabilities as recorded on the books and records of Seller as of April
       30, 1998.  The Cash Portion of the Purchase Price will be adjusted
       (either up or down) based on the aggregate net change in the Net Working
       Capital, Debt and Equipment as of the Closing Date.  The Net Working
       Capital, Debt and Equipment reflected on the Pre-Closing Statement will
       be adjusted as follows:

                     (x)  The amount allocated to equipment will be adjusted by
              deducting the value of equipment reflected on the Pre-Closing
              statement which is sold or disposed of prior to the Closing Date,
              and by adding Seller's cost (including freight) of equipment
              acquired prior to the Closing Date.

                     (y)  The accounts receivable, accrued expenses and
              liabilities will be adjusted to equal the amount of accounts
              receivable and liabilities as of the Closing Date, calculated in
              accordance with GAAP.

                     (z)  The amount of parts inventory will not be adjusted
              unless Buyer conducts (at Buyer's expense) an inventory of the
              parts inventory (in which Seller may participate) and the actual
              cost of parts on hand on the Closing date differs from the value
              thereof on the Pre-Closing Statement by 15%, or more, in which
              case the amount of the actual inventory will be utilized.

       If, upon completion of the procedures set forth in Section 1.5(b) below,
       it is finally determined that (i) the Net Working Capital, Debt and
       Equipment as of the Closing Date is greater than the Net Working
       Capital, Debt and Equipment as shown on the Pre-Closing Statement, then
       the Cash Portion of the Purchase Price shall be increased by the amount
       of such difference in cash, and Buyer shall pay to Seller the amount of
       such difference within ten (10) days after such final determination, or
       (ii) the Net Working Capital, Debt and Equipment as of the Closing Date
       is less than the Net Working Capital, Debt and Equipment as shown on the
       Pre-Closing Statement, then the Cash Portion of the Purchase Price shall
       be decreased by the amount of such difference, and Seller shall pay to
       Buyer the amount of such difference in cash within ten (10) days after
       such final determination.





                                      -6-
<PAGE>   12
              (b)  Within sixty (60) days after the Closing, Buyer will prepare
       and deliver to Seller a statement of the Net Working Capital, Debt and
       Equipment as of the close of business on the Closing Date (the "Closing
       Statement"), which statement shall be prepared in accordance with
       Sections 1.5(a)(x), 1.5(a)(y) and 1.5(a)(z).  If, within thirty (30)
       days following delivery of the Closing Statement to Seller, Seller has
       not given Buyer notice of its objection to the Closing Statement (such
       notice must contain a detailed statement of the basis of Seller's
       objection), then the Net Working Capital, Debt and Equipment reflected
       in the Closing Statement will be used in computing the adjustment to the
       Cash Portion of the Purchase Price.  If Seller gives Buyer such notice
       of objection and the parties are unable to resolve the subject of such
       objection within fifteen (15) days after such notice, then the issues in
       dispute will be submitted to Coopers & Lybrand, LLP, certified public
       accounts (the "Accountants"), for resolution with instructions to the
       Accountants to resolve such dispute within forty-five (45) days.  If
       issues in dispute are submitted to the Accountants for resolution (i)
       each party will furnish to the Accountants such work papers and other
       documents and information relating to the disputed issues as the
       Accountants may request and are available to that party; (ii) the
       determination by the Accountants, as set forth in a notice delivered to
       both parties by the Accountants, will, in the absence of fraud, be
       binding and conclusive on the parties; and (iii) Buyer and Seller will
       each bear 50% of the fees and expenses of the Accountants for such
       determination.  The final determination of the Net Working Capital, Debt
       and Equipment as of the close of business on the Closing Date shall
       occur on the earliest of (A) thirty (30) days after delivery of the
       Closing Statement to Seller without objection, (B) written agreement of
       Seller and Buyer to the Closing Statement or any modification thereof,
       or (C) written determination by the Accountants.

       1.6  Allocation of Purchase Price.  The Purchase Price shall be
allocated among the Assets as set forth on Schedule 1.6. Seller and Buyer shall
report the transactions contemplated hereby on all Tax Returns (including
information returns and supplements thereto required to be filed by the parties
under Section 1060 of the Code) in a manner consistent with such allocation.

       1.7  Liabilities Assumed by Buyer.  As further consideration for the
transfer of the Assets to Buyer, Buyer agrees, upon the terms and subject to
the conditions set forth herein, to assume, at the Closing, and thereafter to
pay, perform, and discharge, the following liabilities and obligations of

Section are collectively referred to herein as the "Assumed Liabilities".

be conducted.  All the Assets are (i) in the case of tangible assets and
properties, in good operating condition and repair (ordinary wear and tear
excepted) and have been maintained in accordance with standard industry
practice, (ii) suitable for the purposes used, and (iii) adequate and
sufficient for the





                                      -12-
<PAGE>   18
normal operation of the Business, as presently conducted.  Seller owns or has a
valid leasehold interest in, or otherwise has a valid right to use, all the
Assets.  To the best knowledge of Seller, the Assets and their uses conform to
all Applicable Laws.

       3.15  Real Property.

       (a)  The Real Property is all the real property owned by Seller and used
or held for use in connection with the operation of the Business.  There are no
persons (other than Seller) in possession of any portion of the Real Property
as lessees, tenants at sufferance, or trespassers, nor does any person (other
than Seller) have a lease, tenancy, or other right of occupancy or use of any
portion of the Real Property.  The Real Property has full and free access to
and from public highways, streets, and roads, and Seller has no knowledge of
any pending or threatened Proceeding or any other fact or condition which would
limit or result in the termination of such access.  There exists no Proceeding
or court order, or building code provision, deed restriction, or restrictive
covenant (recorded or otherwise), or other private or, to the best of Seller's
knowledge, public limitation, which might in any way impede or adversely affect
the continued use of the Real Property by Seller in the manner it is currently
used.

       (b)  All buildings, improvements, and fixtures situated on the Real
Property conform to all Applicable Laws.  All the Real Property is zoned for
the various purposes for which such Real Property is being used, and there
exists no pending or, to the best knowledge of Seller, threatened Proceeding
which might adversely affect the validity of such zoning.

       (c)  The Real Property is connected to and serviced by water, sewage
disposal, gas, telephone, and electric facilities which are adequate for the
current use of the Real Property and, to the best knowledge of Seller, are in
compliance with all Applicable Laws.  All public utilities required for the
operation of the Real Property enter the Real Property through adjoining public
streets or, if they pass through adjoining private land, do so in accordance
with valid public easements, and all utility lines and mains located on the
Real Property have been properly dedicated to, and are serviced and maintained
by, the appropriate public or quasi-public entity.

       (d)  The buildings, improvements, and fixtures situated on the Real
Property are in good condition and repair (excepting ordinary wear and tear and
minor maintenance and repair problems which would normally be associated with
such assets when used in connection with the operation of the Business), free
of any latent or patent structural defects.

       (e)  Neither the whole nor any part of the Real Property is subject to
any pending Proceeding for condemnation or other taking by any Governmental
Entity, and, to the best knowledge of Seller, no such condemnation or other
taking is contemplated or threatened.

       (f)  There are no unpaid charges, debts, liabilities, claims, or
obligations arising from the construction, occupancy, ownership, use, or
operation of the Real Property, or the buildings, improvements, or fixtures
situated thereon, or the business operated thereon, which could give rise to
any mechanic's or materialmen's or other statutory lien against the Real





                                      -13-
<PAGE>   19
Property, or the buildings, improvements, or fixtures situated thereon, or any
part thereof, or for which Seller will be responsible, except for ad valorem
taxes not yet due and payable.

       (g) To the best of Seller's knowledge, the Real Property is not within
any area determined by the Department of Housing and Urban Development to be
flood prone under the Federal Flood Disaster Protection Act of 1973, except a
portion of the Real Property is within an area determined by the Department of
Housing and Urban Development to be flood prone under the Federal Flood
Disaster Protection Act, as reflected on the survey of the Real Property by
James M. Grant of Ralph Harris Surveyors, Inc. dated April 16, 1998.

       (h)  Seller has delivered or made available to Buyer accurate and
complete copies of all title insurance policies, title reports, other title
documents, surveys, certificates of occupancy, and Permits in the possession of
Seller relating to the Real Property or the buildings, improvements, or
fixtures situated thereon.

       (i)  Seller is not a "foreign person" within the meaning of Sections
1445 and 7701 of the Code.

       3.16  Tangible Personal Property.  Set forth on Schedule 3.16 is a list,
as of the dates indicated on such schedule, of all furniture, equipment,
machinery, computer hardware, materials, motor vehicles, rolling stock,
apparatus, tools, implements, appliances, and other tangible personal property
(other than spare parts, supplies, and inventories) owned or leased by Seller
and used or held for use in connection with the operation of the Business,
except for items having a value individually of less than $1,000 which do not,
in the aggregate, have a value exceeding $10,000.  Except as set forth on
Schedule 3.16, the motor vehicles and rolling stock owned or leased by Seller
and used in connection with the operation of the Business are utilized solely
for the transportation by Seller, for its own account and not for the account
of others, of inventories, supplies, and other items relating to the operation
of the Business, and such activities do not require the obtainment of any
Permit.

       3.17  Leased Property. Set forth on Schedule 3.17 is a list of all
leases under which Seller is the lessee or lessor of real or personal property
used or held for use in connection with the operation of the Business.  Seller
has good and valid leasehold interests in all such properties held by it under
lease.  Seller has been in peaceable possession (or remedied any claims
relating thereto) of the property covered by each such lease since the
commencement of the original term of such lease where Seller is the lessee.  To
the best of Seller's knowledge, with respect to leases where the Seller is the
lessor, the lessee under such lease has been in peaceable possession (or
remedied any claims relating thereto) of the property covered by each such
lease since the commencement of the original term of such lease.  No waiver,
indulgence, or postponement of Seller's obligations under any such lease has
been granted by the lessor or the lessee, or of the lessor's or lessee's
obligations thereunder by Seller.  Seller is not in breach of or in default
under, nor has any event occurred which (with or without the giving of notice
or the passage of time or both) would constitute a default by Seller under, any
of such leases, and Seller has not received any notice from, or given any
notice to, any lessor or lessee indicating that Seller or such lessor or lessee
is in breach of or in default under any of such leases.  To the best knowledge
of Seller, none of the lessors or lessees under any of such leases is in breach
thereof or in default thereunder.

Business as first quality goods at normal mark-ups.  No material part of such
inventory is obsolete, discontinued, returned, damaged, overage, or of below
standard quality or merchantability, except for items that have been written
down to realizable market value.  Each item of such inventory is reflected in
Seller's books and records on the basis of a complete physical count and is
valued at the lower of cost, on a first-in, first-out basis, or market in
accordance with GAAP.  The present quantity of such inventory is sufficient to
serve adequately the customers of the Business in the ordinary course.  Seller
also maintains sufficient inventories of spare and replacement parts to meet
any repair and replacement obligations in the ordinary course of the Business,
under applicable warranties or otherwise.  This Section 3.18 is qualified in
its entirety by the matters set forth in Schedule 3.18 hereto.

       3.19  Receivables.  All receivables of Seller generated by the Business
as reflected on the Latest Balance Sheet or arising since the date thereof are
valid obligations of the respective makers thereof, have arisen in the ordinary
course of the Business for goods or services delivered or rendered, are not
subject to any valid defenses, counterclaims, or set offs, and have been
collected or are collectible in full at their recorded amounts in the ordinary
course of the Business without resort to litigation or other extraordinary
collection efforts, net of all cash discounts and doubtful accounts as
reflected on the Latest Balance Sheet (in the case of receivables so reflected)
or on the books of Seller (in the case of receivables arising since the date
thereof).  Seller will not be deemed to be in breach of the foregoing
representations with any receivable to the extent Seller has purchased such
receivable pursuant to Section 6.7 below.

       3.20 Intellectual Property.  Except for the trademarks, service marks,
and trade names set forth on Schedule 3.20, Seller does not own, hold, use, or

service marks, and trade names, free from burdensome restrictions, that are
necessary for the operation of the Assets and the Business as presently
operated.  Seller has not received any written notice or claim of any
infringement, violation, misuse, or misappropriation by Seller in connection
with the operation of the Assets or the Business of any Intellectual Property
owned or purported to be owned by any other person.

       3.21  Permits.  Set forth on Schedule 3.21 is a list of all Permits held

all the Permits necessary or required for the ownership and operation of the
Assets and the conduct of the Business.  Each of such Permits is in full force
and effect, Seller is in compliance with all its obligations with respect
thereto, and, to the best knowledge of Seller, no event has occurred which
permits, or with or without the giving of notice or the passage of time or both
would permit, the revocation or termination of any thereof.  Except as
disclosed on Schedule 3.21, no notice has been issued by any Governmental
Entity and no Proceeding is pending or, to the best knowledge of Seller,
threatened with respect to any alleged failure by Seller to have any Permit.

party or by which Seller is otherwise bound, regardless of amount or subject
matter, that relate to the Assets or the Business are listed on Schedules
1.1(n), 1.1(o), 1.1(q), and 1.5(a).  Seller has delivered or made available to
Buyer accurate and complete copies of the agreements listed on such Schedules.

thereto, enforceable against them in accordance with its terms.  No breach or
default exists with respect to any of such agreements, and no event has
occurred which, after the giving of notice or the passage of time or otherwise,
will result in any such breach or default.

       3.23  ERISA.  During the past five years, neither Seller nor any of its
affiliates have made or been required to make contributions to any
"multiemployer plan", as defined in Section 3(37) of ERISA.  Seller and all the
affiliates of Seller have paid and discharged promptly when due all liabilities
and obligations arising under ERISA or the Code of a character which if unpaid
or unperformed might result in the imposition of a lien against any of the
Assets.  For purposes of this Section only, an "affiliate" of any person means
any other person which, together with such person, would be treated as a single
employer under Section 414 of the Code.

Applicable Laws, and, in the case of the books of account, have been prepared
and maintained in accordance with GAAP consistently applied, except that
Seller's interim financial statements do not reflect accruals for vacation,
sick leave and employment benefit plan contributions.  Such books and records
accurately and fairly reflect, in reasonable detail, all material transactions,
revenues, expenses, assets, and liabilities of Seller with respect to the
Business.

       3.31  Illegal Payments.  To the best knowledge of Seller, none of Seller
or any director, officer, employee, or agent of Seller has, directly or
indirectly, paid or delivered any fee, commission, or other sum of money or
item of property however characterized to any broker, finder, agent, government
official, or other person, in the United States or any other country, in any
manner related to the Assets or the Business, which Seller or any such
director, officer, employee, or agent knows or has reason to believe to have
been illegal under any Applicable Law.

       3.32  Investment Intent.  Subject to the provisions of Section 3.34,
Seller is acquiring the Buyer Shares for its own account for investment and not
with a view to, or for sale or other disposition in connection with, any
distribution of all or any part thereof, except (i) in an offering covered by a
registration statement filed with the Securities and Exchange Commission under
the Securities Act covering the Buyer Shares or (ii) pursuant to an applicable
exemption under the Securities Act.  In acquiring the Buyer Shares Seller is
not offering or selling, and will not offer or sell, for Buyer in connection
with any distribution of the Buyer Shares, and Seller does not have a
participation and will not participate in any such undertaking or in any
underwriting of such an undertaking except in compliance with applicable
federal and state securities laws.

       3.33  Investment Experience.  Seller acknowledges that it is able to
fend for itself, can bear the economic risk of its investment in the Buyer
Shares, and has such knowledge and experience in financial and business matters
that it is capable of evaluating the merits and risks of an investment in the
Buyer Shares.  Seller represents that it has not been organized for the purpose
of acquiring the Buyer Shares.  Seller is an "accredited investor" as such term
is defined in Regulation D under the Securities Act.  Nothing in this Section
3.33 relieves Buyer from liability with respect to the Buyer's representations
and warranties, including, without limitation, those contained in Section 4.7
below.

       3.34  Restricted Securities.  Seller understands that the Buyer Shares
will not have been registered pursuant to the Securities Act or any applicable
state securities laws, that the Buyer Shares will be characterized as
"restricted securities" under federal securities laws, and that under such laws
and applicable regulations the Buyer Shares cannot be sold or otherwise
disposed of without registration under the Securities Act or an exemption
therefrom.  In this connection, Seller represents that it is familiar with Rule
144 promulgated under the Securities Act, as currently in effect, and
understands the resale limitations imposed thereby and by the Securities Act.
Stop transfer instructions may be issued to the transfer agent for securities
of Buyer (or a notation may be made in the appropriate records of Buyer) in
connection with the





                                      -19-
<PAGE>   25
Buyer Shares.  However, Seller contemplates that it will, prior to December 31,
1998 liquidate and distribute its assets, including the Buyer Shares, to the
Shareholders.  Subject to compliance with applicable securities laws, Buyer
agrees to honor a transfer of the Buyer Shares to the Shareholders when the
certificates representing the Buyer Shares are presented to Buyer, properly
endorsed for transfer to the Shareholders.  Shareholders understand that,
notwithstanding any such transfer, the Buyer Shares will remain restricted
securities under Rule 144 for the period of time provided in that rule, and
that their certificates will contain the legend set forth in Section 3.35.

       3.35  Legend.  It is agreed and understood by Seller that the
certificates representing the Buyer Shares shall each conspicuously set forth
on the face or back thereof, in addition to any legends required by Applicable
Law or other agreement, a legend in substantially the following form:

       THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
       PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
       SECURITIES LAWS.  SUCH SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED
       UNLESS THEY ARE FIRST REGISTERED PURSUANT TO THAT ACT AND APPLICABLE
       STATE SECURITIES LAWS OR UNLESS THE CORPORATION RECEIVES A WRITTEN
       OPINION OF COUNSEL, WHICH OPINION AND COUNSEL ARE SATISFACTORY TO THE
       CORPORATION, TO THE EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.

       3.36  Brokerage Fees.  Neither Seller nor any of its affiliates has
retained any financial advisor, broker, agent, or finder or paid or agreed to
pay any financial advisor, broker, agent, or finder on account of this
Agreement or any transaction contemplated hereby.

       3.37  Representations and Warranties on Closing Date.  The
representations and warranties made in this Article III will be true and
correct on and as of the Closing Date with the same force and effect as if such
representations and warranties had been made on and as of the Closing Date,
except that any such representations and warranties which expressly relate only
to an earlier date shall be true and correct on the Closing Date as of such
earlier date.

                                   ARTICLE IX

                       TERMINATION, AMENDMENT, AND WAIVER

              15, 1998, unless such failure to close shall be due to a breach
              of this Agreement by the party seeking to terminate this
              Agreement pursuant to this clause (i); or

                     (ii)  there shall be any statute, rule, or regulation that
              makes consummation of the transactions contemplated hereby
              illegal or otherwise prohibited or a Governmental Entity shall
              have issued an order, decree, or ruling or taken any other action
              permanently restraining, enjoining, or otherwise prohibiting the
              consummation of the transactions contemplated hereby, and such
              order, decree, ruling, or other action shall have become final
              and nonappealable; or

              (c)  by Seller, if (i) any of the representations and warranties
       of Buyer contained in this Agreement shall not be true and correct in

       Closing as if made at and as of such time, or (ii) Seller or any
       Shareholders shall have failed to fulfill in any respect any of its
       obligations under this Agreement, and, in the case of each of clauses
       (i) and (ii), such misrepresentation, breach of warranty, or failure

       9.2  Effect of Termination.  In the event of the termination of this
Agreement pursuant to Section 9.1 by Seller or Buyer, written notice thereof
shall forthwith be given to the other party specifying the provision hereof
pursuant to which such termination is made, and this Agreement shall become
void and have no effect, except that the agreements contained in this Section
and in Article X and Sections 6.9, 6.14, 12.1, 12.4 and 12.5 shall survive the
termination hereof.  Nothing contained in this Section shall relieve any party
from liability for damages actually incurred as a result of any breach of this
Agreement.

       9.3  Amendment.  This Agreement may not be amended except by an
instrument in writing signed by or on behalf of all the parties hereto.

       9.4  Waiver.  Each of Seller and Buyer may (i) waive any inaccuracies in
the representations and warranties of the other contained herein or in any
document, certificate, or writing delivered pursuant hereto or (ii) waive
compliance by the other with any of the other's agreements or fulfillment of
any conditions to its own obligations contained herein.  Any agreement on the
part of a party hereto to any such waiver shall be valid only if set forth in
an instrument in writing signed by or on behalf of such party.  No failure or
delay by a party hereto in exercising any right, power, or privilege hereunder
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power, or privilege.

       9.5  Remedies Not Exclusive.  The rights and remedies herein provided
shall be cumulative and not exclusive of any rights or remedies provided by
law.  The rights and remedies of any party based upon, arising out of, or
otherwise in respect of any inaccuracy in or breach of any representation,
warranty, covenant, or agreement contained in this Agreement shall in no way be
limited by the fact that the act, omission, occurrence, or other state of facts
upon which any claim of any such inaccuracy or breach is based may also be the
subject matter of any other representation, warranty, covenant, or agreement
contained in this Agreement (or in any other agreement between the parties) as
to which there is no inaccuracy or breach.

                                   ARTICLE X

                          SURVIVAL OF REPRESENTATIONS;
                                INDEMNIFICATION

       10.1  Survival.  The representations and warranties of the parties
hereto contained in this Agreement or in any certificate, instrument, or
document delivered pursuant hereto and the related indemnity provisions shall
survive the Closing and for the two year period thereafter, regardless of any
investigation made by or on behalf of any party.

       10.2  Indemnification by Seller and Shareholder.  Subject to the terms
and conditions of this Article X, Seller and the Shareholders each jointly and
severally shall indemnify, defend, and hold harmless Buyer, the subsidiaries
and parent corporations of Buyer, each director, officer, employee, and agent
of Buyer or any of its subsidiaries or parent corporations, and each affiliate
of Buyer and its subsidiaries and parent corporations, and their respective
heirs, legal representatives, successors, and assigns (collectively, the "Buyer
Group"), from and against any and all claims, actions, causes of action,
demands,





                                      -33-
<PAGE>   39
assessments, losses, damages, liabilities, judgments, settlements, penalties,
costs, and expenses (including reasonable attorneys' fees and expenses), of any
nature whatsoever, whether actual or consequential (collectively, "Damages"),
asserted against, resulting to, imposed upon, or incurred by any member of the
Buyer Group, directly or indirectly, by reason of or resulting from any of the
following:

              (a)  any inaccuracy in or breach of any representation or
       warranty of Seller or any Shareholder contained in this Agreement or in
       any certificate, instrument, or document delivered pursuant hereto;

              (b)  any breach by Seller or any Shareholder of any of its or his
       covenants or agreements contained in this Agreement or in any
       certificate, instrument, or document delivered pursuant hereto;

              (c) except as set forth in Section 3.24(g), any liability or
       obligation of Seller or its affiliates (whether accrued, absolute,
       contingent, unliquidated, or otherwise, whether or not known to Seller
       or any Shareholder, and whether due or to become due), other than the
       Assumed Liabilities;

              (d)  except as set forth in Section 3.24(g), the ownership,
       management, or use of the Assets or the Business prior to the Closing
       Date; or

              (e)  any products or equipment distributed, sold or leased by
       Seller in connection with the Business on or prior to the Closing Date.

       10.3  Indemnification by Buyer.  Subject to the terms and conditions of
this Article X, Buyer shall indemnify, defend, and hold harmless each
Shareholder, Seller, each director, officer, employee, and agent of Seller, and
each affiliate of Seller, and their respective heirs, legal representatives,
successors, and assigns (collectively, the "Seller Group"), from and against
any and all Damages asserted against, resulting to, imposed upon, or incurred
by any member of the Seller Group, directly or indirectly, by reason of or
resulting from any of the following:

              (a)  any inaccuracy in or breach of any representation or
       warranty of Buyer contained in this Agreement or in any certificate,
       instrument, or document delivered pursuant hereto;

              (b)  any breach by Buyer of any of its covenants or agreements
       contained in this Agreement or in any certificate, instrument, or
       document delivered pursuant hereto;

              (c)  the Assumed Liabilities;

              (d)  the ownership, management, or use by Buyer of the Assets
       from and after the Closing Date, except to the extent Buyer is
       indemnified by Seller with respect to such matters pursuant to Section
       10.2; and





                                      -34-
<PAGE>   40
              (e)  any products or equipment leased, distributed or sold by
       Buyer from and after the Closing Date, except to the extent Buyer is
       indemnified by Seller with respect to such matters pursuant to Section
       10.2.

       10.4  Procedure for Indemnification.  Promptly after receipt by an
indemnified party under Section 10.2 or 10.3 of notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to
be made against an indemnifying party under such Section, give written notice
to the indemnifying party of the commencement thereof, but the failure so to
notify the indemnifying party shall not relieve it of any liability that it may
have to any indemnified party except to the extent the indemnifying party
demonstrates that the defense of such action is prejudiced thereby.  In case
any such action shall be brought against an indemnified party and it shall give
written notice to the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it may wish, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party.  If the indemnifying party elects to
assume the defense of such action, the indemnified party shall have the right
to employ separate counsel at its own expense and to participate in the defense
thereof.  If the indemnifying party elects not to assume (or fails to assume)
the defense of such action, the indemnified party shall be entitled to assume
the defense of such action with counsel of its own choice, at the expense of
the indemnifying party.  If the action is asserted against both the
indemnifying party and the indemnified party and there is a conflict of
interests which renders it inappropriate for the same counsel to represent both
the indemnifying party and the indemnified party, the indemnifying party shall
be responsible for paying for separate counsel for the indemnified party;
provided, however, that if there is more than one indemnified party, the
indemnifying party shall not be responsible for paying for more than one
separate firm of attorneys to represent the indemnified parties, regardless of
the number of indemnified parties.  If the indemnifying party elects to assume
the defense of such action, (a) no compromise or settlement thereof may be
effected by the indemnifying party without the indemnified party's written
consent (which shall not be unreasonably withheld) unless the sole relief
provided is monetary damages that are paid in full by the indemnifying party
and (b) the indemnifying party shall have no liability with respect to any
compromise or settlement thereof effected without its written consent (which
shall not be unreasonably withheld).

       10.5   Basket.  Notwithstanding the foregoing, neither party is liable
to the other party for a breach of a representation or warranty until the
amount of the indemnified party's Damages exceeds $25,000, but if such Damages
exceed $25,000, then the indemnifying party is liable for all of the Damages.

                                   ARTICLE XI

                              REGISTRATION RIGHTS

       11.1  Right to Participate in Registration. If, at any time prior to the
first anniversary date of the Closing date, Buyer proposes to register shares
of Common Stock under the Securities Act, on Form S-1, S-2, or S-3 (or any form
which replaces or is substantially similar to such form), the Company shall
give notice of such proposed registration to Seller.  Subject to the terms and
provisions of this Article XI, upon the request of Seller made within





                                      -35-
<PAGE>   41
20 days after the giving of such notice by Buyer, Buyer shall use its best
efforts to cause all shares of Buyer Shares that have been acquired by Seller
or the Shareholders pursuant hereto, which shares Seller shall have requested
to be included in the proposed registration ("Registrable Shares"), to be
included in such registration to the extent requisite to permit the sale or
other disposition by Seller or the Shareholders of such Registrable Shares.  In
the event the offering to be conducted pursuant to the proposed registration is
to be an underwritten public offering, the registration rights provided in this
Article XI shall be subject to the approval of the managing underwriter or
underwriters of such offering, who shall determine the number of Registrable
Shares, if any, that may be included in such registration without adversely
affecting such offering; provided, however, Buyer agrees to use commercially
reasonable efforts to cause all Registrable Shares that the Seller or the
Shareholders desire to register to be included in such offering.

       11.2  Registration Procedures. If and whenever Buyer is required by the
provisions of this Article XI to use its best efforts to cause Registrable
Shares to be included in the registration of securities of Buyer under the
Securities Act, Buyer will, as expeditiously as possible:

              (a)  prepare and file with the Securities and Exchange Commission
       (the "Commission") a registration statement (the "Registration
       Statement") covering such Registrable Shares and use its best efforts to
       cause the Registration Statement to become effective and to remain
       effective for so long as may reasonably be necessary to complete the
       sale or other disposition of such Registrable Shares, provided that the
       Company shall not in any event be required to use its best efforts to
       maintain the effectiveness of the Registration Statement for a period in
       excess of [90] days;

              (b)  prepare and file with the Commission such amendments and
       supplements to the Registration Statement and the prospectus contained
       therein as may be necessary to keep the Registration Statement
       effective, and comply with the provisions of the Securities Act, with
       respect to the sale or other disposition of the Registrable Shares
       whenever Seller or the Shareholders desire to sell or otherwise dispose
       of the same but only to the extent provided in this Section 11.2;

              (c)  furnish to Seller or the Shareholders such numbers of copies
       of the Registration Statement, the prospectus contained therein
       (including each preliminary prospectus), and each amendment and
       supplement to the Registration Statement and such prospectus, in
       conformity with the requirements of the Securities Act, and such other
       documents, as Seller or the Shareholders may reasonably request in order
       to facilitate the sale or other disposition of the Registrable Shares;

              (d)  use reasonable efforts to register or qualify the
       Registrable Shares for sale under the securities or blue sky laws of
       such jurisdictions as the Seller or the Shareholders may reasonably
       request, and do any and all other acts and things that may be necessary
       under such securities or blue sky laws to enable Seller to consummate
       the sale or other disposition of the Registrable Shares in such
       jurisdictions, provided that Buyer shall not in any event be required to
       register or qualify the Registrable Shares for sale under the securities
       or blue sky laws of more than the number of states in which





                                      -36-
<PAGE>   42
       Buyer is registering its own shares, and provided further, that Buyer
       shall not in any event be required to keep any such registration or
       qualification in effect after the expiration of the period during which
       Buyer maintains the effectiveness of the Registration Statement and
       shall not for any such purpose be required to qualify to do business as
       a foreign corporation in any jurisdiction wherein it is not so qualified
       or to subject itself to taxation in any such jurisdiction; and

              (e)  before filing the Registration Statement, any prospectus to
       be used in connection with the offering to be conducted pursuant to such
       registration, or any amendments or supplements to the Registration
       Statement or such prospectus with the Commission, furnish counsel to
       Seller or the Shareholders with copies of all such documents proposed to
       be filed.

       11.3  Required Information.  Buyer shall not be required to use its best
efforts to include any Registrable Shares in a proposed registration of its
securities under the Securities Act unless and until (i) Seller and the
Shareholders furnish to Buyer such information regarding Seller, the
Shareholders and such Registrable Shares and the intended method of disposition
of such Registrable Shares as Seller shall reasonably request in order to
satisfy the requirements applicable to such registration, and (ii) in the event
the offering to be conducted pursuant to such registration is to be an
underwritten public offering, such Seller or the Shareholders agree to the
terms of the underwriting agreed to between Buyer and the underwriter or
underwriters of such offering and executes all documents reasonably required to
effect such offering.

       11.4  Expenses of Registration.  In the event of the inclusion pursuant
to the provisions of this Article XI of Registrable Shares in a registration by
Buyer of its securities under the Securities Act, Seller or the Shareholders'
shall pay any federal and blue sky filing and registration or qualification
fees solely attributable to Seller's or the Shareholders' Registrable Shares,
any brokerage and underwriting discounts and commissions payable in respect of
Registrable Shares sold on Seller's or the Shareholders' behalf, all fees and
expenses of any attorneys and accountants employed by Seller, and any other
costs directly incurred by Seller.

       11.5  Indemnification.  In connection with any registration of
Registrable Shares pursuant to the provisions of this Article XI, Buyer shall
indemnify and hold harmless Seller and the Shareholders to the extent that
companies generally indemnify and hold harmless underwriters in connection with
public offerings under the Securities Act, and Seller and each Shareholder
shall jointly and severally indemnify and hold harmless Buyer, each director
and officer of Buyer, and each person who controls Buyer within the meaning of
the Securities Act to the extent that selling shareholders generally indemnify
and hold harmless issuers of securities in connection with public offerings
under the Securities Act with respect to the written information provided by
Seller for use by Buyer in the preparation of the Registration Statement.
However, the liability of Seller and the Shareholders will not be joint and
several, but will be pro rata based on the number of Registrable Shares
included in the offering.
