by reason of that Person's right, if any, to vote shares of the Capital Stock of
the Company or any Company Subsidiary it holds, any right to vote on any matter
with the holders of Capital Stock of the Company or any Company Subsidiary.

Related Party Agreements specifically referred to in Schedule 2.11 as "Retained
Related Party Agreements" (the "Retained Related Party Agreements"), each
Related Party Agreement in effect on the date hereof will have been terminated,
and all Indebtedness of each Related Person and its Affiliates owed to any of
the Company and the Company Subsidiaries will have been paid in full, prior to
the Effective Time, and no Related Party Agreement then will exist. The terms
and conditions of each of the Retained Related Party Agreements are no less
favorable to the Company than the Company reasonably could have expected to
obtain in an arm's-length transaction with a Person other than an Affiliate of
the Company, the rentals provided for in the Retained Related Party Agreements
constituting leases of property to the Acquired Business do not and will not
exceed fair market rentals of the properties being rented or leased under those

Company Subsidiary then had any outstanding Indebtedness to any Person or any
liabilities of any kind (including contingent obligations, tax assessments or
unusual forward or long-term commitments), or any unrealized or anticipated
loss, which in the aggregate then were Material to the Company and required to
be reflected in those Financial Statements or in the notes related thereto in
accordance with GAAP which were not so reflected.

the business, operations, properties or assets, liabilities, condition

Subsidiary that could reasonably be expected, either alone or together with all
other such changes, to have a Material Adverse Effect.

Agreement in connection with the transactions contemplated hereby is, taken
together, true and correct in all material respects and does not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein not materially misleading in
light of the circumstances under which those statements were made.

the Code (the "Qualified Plans") are so qualified and the terms of the Plans, as
amended to date, have been determined by the IRS to be so qualified (or
applications for determination letters have been timely submitted to the IRS

these Qualified Plans have not expired and will not expire within 120 days after
the Effective Time. All reports and other documents required to be filed with
any governmental agency or distributed to plan participants or beneficiaries

                 --------------------------------                               
Plan or the Company or any Company Subsidiary has engaged in any Prohibited
Transaction. No Plan has incurred an accumulated funding deficiency, as defined
in section 412(a) of the Code and section 302(a) of ERISA, and no circumstances
exist pursuant to which the Company or any Company Subsidiary could have any
direct or indirect liability whatsoever (including being subject to any
statutory Lien to secure payment of any such liability), to the Pension Benefit
Guaranty Corporation under Title IV of ERISA or to the IRS for any excise tax or
penalty with respect to any Plan or ERISA Affiliate Pension Plan previously,
now, or hereafter maintained or contributed to by the Company, any Company
Subsidiary or any of their ERISA Affiliates. Further:

          (i)    there have been no terminations, partial terminations or

     determination by the IRS that such action does not adversely affect the 
     tax-qualified status of that plan;

          (ii)   no Termination Event has occurred;

          (iii)  no Reportable Event has occurred with respect to any Plan that
     was not timely and properly reported to the Pension Benefit Guaranty

     Effective Time, shall equal or exceed the actuarial present value of all
     "benefit liabilities" (within the meaning of section 4001(a)(16) of ERISA)
     under that plan in accordance with the assumptions contained in the
     regulations of the Pension Benefit Guaranty Corporation governing the
     funding of terminated defined benefit plans;

          (v)    with respect to Plans that are "group health plans" subject to

     regulations (relating to the 

                                     -16-

     benefit continuation rights imposed by "COBRA" or qualified medical child
     support orders), the Company, each Company Subsidiary and the Stockholders
     have complied (and at the Effective Time will have complied) in all
     material respects with all reporting, disclosure, notice, election and
     other benefit continuation and coverage requirements imposed thereunder as
     and when applicable to those plans, and neither the Company nor any Company
     Subsidiary has incurred (or will incur) any direct or indirect liability or
     is (or will be) subject to any loss, assessment, excise tax penalty, loss
     of federal income tax deduction or other sanction, arising on account of or
     in respect of any direct or indirect failure by the Company, any Company
     Subsidiary or any Stockholder, at any time prior to the Effective Time, to
     comply with any such federal or state benefit continuation or coverage
     requirement, which is capable of being assessed or asserted before or after
     the Effective Time directly or indirectly against the Company, any Company
     Subsidiary, any Stockholder, ARS or any Subsidiary of ARS with respect to
     any of those group health plans;

          (vi)   the Financial Statements as of the Current Balance Sheet Date
     reflect the approximate total pension, medical and other benefit liability
     for all Plans, and no material funding changes or irregularities are
     reflected thereon that would cause those Financial Statements to be not
     representative of prior periods; and

          (vii)  neither the Company nor any Company Subsidiary has incurred
     liability under Section 4062 of ERISA.

          (e)    Multiemployer Plans.  Except as set forth in Schedule 2.26,

neither the Company nor any Company Subsidiary, and no ERISA Affiliate of any of
them, is, or at any time during the six-year period ended on the date hereof
was, obligated to contribute to a Multiemployer Plan. Neither the Company nor
any Company Subsidiary, and no ERISA Affiliate of any of them, has made a
complete or partial withdrawal from a Multiemployer Plan so as to incur
withdrawal liability as defined in Section 4201 of ERISA. Schedule 2.26 lists
for each Multiemployer Plan on such Schedule the Company's best estimate of the
amount of withdrawal liability that would be incurred if the Company and each of
its ERISA Affiliates were to make a complete withdrawal from such Multiemployer
Plan as of the Closing Date. Except as set forth in Schedule 2.26, the aggregate
amount of such withdrawal liability if the Company and each of its ERISA
Affiliates were to make a complete withdrawal from each such Multiemployer Plan
would not exceed $25,000.

          (f)    Claims and Litigation.  Except as set forth in Schedule 2.26, 
                 ---------------------        
no Litigation or claims (other than routine claims for benefits) are pending or,
to the knowledge of the Company, threatened against, or with respect to, any of
the Plans or with respect to any fiduciary, administrator or sponsor thereof (in
their capacities as such), or any party-in-interest thereof.

          (g)    Excise Taxes, Damages and Penalties.  No act, omission or
                 -----------------------------------                      
transaction has

occurred which would result in the imposition on the Company or any Company
Subsidiary of (i) breach of fiduciary duty liability damages under section 409
of ERISA, (ii) a civil penalty assessed pursuant to subsection (c), (i) or (l)
of section 502 of ERISA or (iii) any excise tax under applicable provisions of
the Code with respect to any Plan.

          (h)    Welfare Trusts.  Any trust funding a Plan, which is intended 
                 --------------     
to be exempt from federal income taxation pursuant to section 501(c)(9) of the
Code, satisfies the requirements of that section and has received a favorable
determination letter from the IRS regarding that exempt status and has not,
since receipt of the most recent favorable determination letter, been amended or
operated in a way that would adversely affect that exempt status.

                         -----

Company Subsidiary has been timely paid and adequate reserves have been
established on the consolidated books of the Company and the Company
Subsidiaries for all Taxes for which any of the Company and the Company
Subsidiaries is liable, but the payment of which is not yet due. Neither the
Company nor any Company Subsidiary is, or ever has been, liable for any Tax
payable by reason of the income or property of a Person other than the Company
or a Company Subsidiary. Each of the Company and the Company Subsidiaries has
timely filed true, correct and complete declarations of estimated Tax in each
jurisdiction in which any such declaration is required to be filed by it. No
Liens for Taxes exist upon the assets of the Company or any Company Subsidiary
except Liens for Taxes which are not yet due. Neither the Company nor any
Company Subsidiary is, or ever has been, subject to Tax in any jurisdiction
outside of the United States. No Litigation with respect to any Tax for which
the Company or any Company Subsidiary is asserted to be liable is pending or, to
the knowledge of the Company or any Stockholder, threatened and no basis which
the Company or any Stockholder believes to be valid exists on which any claim
for any such Tax can be asserted against the Company or any Company Subsidiary.
There are no requests for rulings or determinations in respect of any Taxes
pending between the Company or any Company Subsidiary and any Taxing Authority.
No extension of any period during which any Tax may be assessed or collected and
for which the Company or any Company Subsidiary is or may be liable has been
granted to any Taxing Authority. Neither the Company nor any Company Subsidiary
is or has been a partor sharing agreement. All amounts required to be withheld
by any of the Company and the Company Subsidiaries and paid to governmental
agencies for income, social security, unemployment insurance, sales, excise, use
and other Taxes have been collected or withheld and paid to the proper Taxing
Authority. The Company and each Company Subsidiary have made all deposits
required by law to be made with respect to employees' withholding and other
employment taxes.

of the Code or any comparable provision of any other tax statute and has not
agreed to have Section 341(f)(2) of the Code or any comparable provision of any
other tax statute apply to any disposition of an asset. The Company has not
made, is not obligated to make and is not a party to any agreement that could
require it to make any payment that is not deductible under Section 280G of the
Code. No asset of the Company or of any Company Subsidiary is subject to any
provision of applicable law which eliminates or reduces the allowance for
depreciation or amortization in respect of that asset below the allowance

rulings or other determinations by Taxing Authorities and records concerning the
ownership and Tax bases of property as are relevant which a party possesses.
Each party will make its employees, if any, reasonably available on a mutually

efforts to ensure that, within 90 days after the Effective Time, either (a) the
Stockholder Guaranties, if any, listed in Schedule 6.02 are terminated or (b)
the Indebtedness to which those Guaranties relate is retired; provided, however,
that if ARS is unable to effect the termination of any of those Guaranties or
the retirement of any of that Indebtedness, ARS will indemnify and hold harmless
each Stockholder from and against any liabilities, claims, demands, judgments,
losses, costs, damages or expenses whatsoever (including reasonable attorneys'
fees) that such Stockholder may sustain, suffer or incur and that result from or
arise out of or relate to that Guaranty or that Indebtedness, as the case may
be.

          Section 6.03. Undertakings by Certain Stockholders.  Each Stockholder
                        ------------------------------------                   
who is a Restricted Person covenants that:  (a) the Stockholder will not
publicly offer or sell or solicit an offer to buy any of the shares of ARS
Common Stock, or any part of the Convertible Notes (or any shares of ARS Common
Stock issued on conversion of those Convertible Notes), issued to the
Stockholder pursuant to Paragraph 2 unless:  (i) those securities are sold in
compliance with paragraphs (c), (e), (f) and (g) of Securities Act Rule 144;
(ii) those securities have been registered under the Securities Act for resale
pursuant to a registration statement then in effect; (iii) the Stockholder is
not an Affiliate of ARS, a period of at least one year (or such shorter period
as the SEC may prescribe for purposes of Securities Act Rule 145(d)(2)) has
elapsed since the Effective Time and ARS meets the requirements of Securities
Act Rule 144(c); or (iv) the Stockholder is not, and has not been for at least
three months, an Affiliate of ARS and a period of at least two years (or such
shorter period as the SEC may prescribe for purposes of Securities Act Rule
145(d)(3)) has elapsed since the Effective Time; and (b) if the Stockholder does
sell, assign, pledge, hypothecate, transfer or otherwise dispose of any of those
securities to any Restricted Person, the Stockholder will cause that Restricted
Person to execute and deliver to ARS a written agreement pursuant to

                                      -32-
<PAGE>
 
which that Restricted Person agrees to be bound by the provisions of this
Section 6.03 with respect to those securities. Each Restricted Person bound by
the provisions of this Section 6.03 agrees with ARS that all certificates
evidencing shares of ARS Common Stock, or Convertible Notes (or any shares of
ARS Common Stock issued on conversion of those Convertible Notes), issued
pursuant to Paragraph 2 will bear the following legend while owned of record or
beneficially by that Restricted Person:

     THE SECURITIES REPRESENTED HEREBY WERE ISSUED IN A TRANSACTION
     CONSTITUTING A "BUSINESS COMBINATION" WITHIN THE MEANING OF RULE
     145 UNDER THE SECURITIES ACT OF 1933 TO A PERSON WHO WAS AN
     "AFFILIATE" OF A PARTY TO THAT TRANSACTION (OTHER THAN THE
     ISSUER) PURSUANT TO THE [TITLE OF ACQUISITION AGREEMENT] AMONG
     THE ISSUER, [NAME OF COMPANY] AND THE OTHER PERSONS PARTIES
     THERETO AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF WITHOUT
     COMPLIANCE WITH THE PROVISIONS OF THAT AGREEMENT AND THE
     REGISTRATION PROVISIONS OF THE SECURITIES ACT OF 1933 OR AN
     APPLICABLE EXEMPTION THEREFROM. A COPY OF THE [TITLE OF
     ACQUISITION AGREEMENT] MAY BE OBTAINED FREE OF CHARGE BY

As used in this Section 6.03, "Restricted Person" means at any time:  (a) each
Stockholder named as an Affiliate of the Company in Schedule 2.06; and (b) each
other Person who, pursuant to Securities Act Rule 144(a)(2), would be treated
together at that time with any Stockholder named as an Affiliate of the Company
in Schedule 2.06 as a single "person" for purposes of determining the compliance
of that "person" with Securities Act Rule 144(e).

                                INDEMNIFICATION

          Section 7.1.  Survival of Representations and Warranties.  All the
                        ------------------------------------------          
provisions of this Agreement will survive the Closing and Effective Time
indefinitely notwithstanding any investigation at any time made by or on behalf
of any party hereto or the provision of any Supplemental Information pursuant to
Section 4.07, provided that the representations and warranties set forth in (or
deemed by any of the Special Provisions to be set forth in) Articles I, II and
III and in any certificate delivered in connection herewith with respect to any
of those representations and warranties will terminate and expire on the second
anniversary of the Effective Date, except as follows:  (a) the representations
and warranties of the Stockholders which relate expressly or by necessary
implication to Taxes, ERISA or other employment or labor matters will survive
until the expiration of the applicable statutes of limitations (including all
periods of extension and tolling); (b) the representations and warranties of the
Stockholders which relate expressly or by necessary implication to the
environment or Environmental Laws will survive for a period of five years from
the Effective Date; (c) the representations and warranties of the

                                      -33-
<PAGE>
 
Stockholders set forth in Sections 1.01 and 1.02 will survive forever; (d) if
the Company is not included in the Acquired Business, the representations and
warranties of the Company specified in Schedule 7.01, if any, will survive
forever and the representations and warranties of the Company in Article II will
expire as when the representations and warranties of the Stockholders to the
same effect expire; and (e) if the Company is included in the Acquired Business,
the representations and warranties of the Company will terminate and expire at
the Effective Time. After a representation and warranty has terminated and
expired, no indemnification will or may be sought pursuant to this Article VII
on the basis of that representation and warranty by any Person who would have
been entitled pursuant to this Article VII to indemnification on the basis of
that representation and warranty prior to its termination and expiration,
provided that: (a) the amount of that claim, if against the Company or any
Stockholder, shall be taken into account in determining whether the aggregate
amount of all claims against the Company or that Stockholder has exceeded the
Threshold Amount or that Stockholder's Pro Rata Share of the Threshold Amount
for purposes of Section 7.06; and (b) in the case of each representation and
warranty that will terminate and expire as provided in this Section 7.01, no
claim presented in writing for indemnification pursuant to this Article VII on
the basis of that representation and warranty prior to its termination and
expiration will be affected in any way by that termination and expiration.

          Section 7.2.  Indemnification of ARS Indemnified Parties.  (a) Subject
                        ------------------------------------------              
to the applicable provisions of Sections 7.01 and 7.06, the Stockholders
covenant and agree that they, jointly and severally, will indemnify each ARS
Indemnified Party against, and hold each ARS Indemnified Party harmless from and
in respect of, all Damage Claims that arise from, are based on or relate or
otherwise are attributable to (i) any breach of the representations and
warranties of the Stockholders or the Company set forth herein (other than in
Article I) or in certificates delivered in connection herewith (other than in
respect of certificates relating only to the representations and warranties in
Article I), (ii) any nonfulfillment of any covenant or agreement on the part of
the Stockholders or the Company under this Agreement or (iii) any Environmental
Liability arising from or related to any event, condition, action or incident
existing or occurring prior to the Closing Date (each such Damage Claim and each
Damage Claim described in Section 7.02(b) being an "ARS Indemnified Loss").

          (b) Each Stockholder, severally and not jointly with any other Person,
covenants and agrees that he will indemnify each ARS Indemnified Party against,
and hold each ARS Indemnified Party harmless from and in respect of, all Damage
Claims that arise from, are based on or relate or otherwise are attributable to
(i) any breach of the representations and warranties of that Stockholder solely
as to that Stockholder set forth in Article I or in certificates delivered by
that Stockholder and relating to those representations and warranties or (ii)
any nonfulfillment of any several agreement on the part of that Stockholder in
this Agreement.

          Section 7.3.  Indemnification of Stockholder Indemnified Parties.  ARS
                        --------------------------------------------------      
covenants and agrees that it will indemnify each Stockholder Indemnified Party
against, and hold each Stockholder Indemnified Party harmless from and in
respect of, all Damage Claims that arise from,

                                      -34-
<PAGE>
 
are based on or relate or otherwise are attributable to (a) any breach by ARS of
its representations and warranties set forth herein or in its certificates, if
any, delivered to the Company or the Stockholders in connection herewith or (b)
any nonfulfillment of any covenant or agreement on the part of ARS or ARS Sub in
this Agreement (each such Damage Claim being a "Stockholder Indemnified Loss").

          Section 7.4.  Conditions of Indemnification.  (a)  All claims for
                        -----------------------------                      
indemnification under this Agreement shall be asserted and resolved as follows
in this Section 7.04.

          (b) A party claiming indemnification under this Agreement (an
"Indemnified Party") shall promptly (i) notify the party from whom
indemnification is sought (the "Indemnifying Party") of any third-party claim or
claims asserted against the Indemnified Party ("Third Party Claim") that could
give rise to a right of indemnification under this Agreement and (ii) transmit
to the Indemnifying Party a written notice ("Claim Notice") describing in
reasonable detail the nature of the Third Party Claim, a copy of all papers
served with respect to that claim (if any), an estimate of the amount of damages
attributable to the Third Party Claim to the extent feasible (which estimate
shall not be conclusive of the final amount of that claim) and the basis for the
Indemnified Party's request for indemnification under this Agreement.  Except as
set forth in Section 7.01, the failure to promptly deliver a Claim Notice shall
not relieve the Indemnifying Party of its obligations to the Indemnified Party
with respect to the related Third Party Claim except to the extent that the
resulting delay is materially prejudicial to the defense of that claim.  Within
15 days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Party shall notify the Indemnified Party (i) whether the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article VII with respect to that Third Party Claim and (ii) if the
Indemnifying Party does not dispute its potential liability to the Indemnified
Party with respect to that Third Party Claim, whether the Indemnifying Party
desires, at the sole cost and expense of the Indemnifying Party, to defend the
Indemnified Party against that Third Party Claim.

          (c) If the Indemnifying Party does not dispute its potential liability
to the Indemnified Party and notifies the Indemnified Party within the Election
Period that the Indemnifying Party elects to assume the defense of the Third
Party Claim, then the Indemnifying Party shall have the right to defend, at its
sole cost and expense, that Third Party Claim by all appropriate proceedings,
which proceedings shall be prosecuted diligently by the Indemnifying Party to a
final conclusion or settled at the discretion of the Indemnifying Party in
accordance with this Section 7.04(c), and the Indemnified Party will furnish the
Indemnifying Party with all information in its possession with respect to that
Third Party Claim and otherwise cooperate with the Indemnifying Party in the
defense of that Third Party Claim; provided, however, that the Indemnifying
Party shall not enter into any settlement with respect to any Third Party Claim
that purports to limit the activities of, or otherwise restrict in any way, any
Indemnified Party or any Affiliate of any Indemnified Party without the prior
consent of that Indemnified Party (which consent may be withheld in the sole
discretion of that Indemnified Party).  The Indemnified Party is hereby
authorized, at the sole cost and expense of the Indemnifying Party, to file,
during the

                                      -35-
<PAGE>
 
Election Period, any motion, answer or other pleadings that the Indemnified
Party shall deem necessary or appropriate to protect its interests or those of
the Indemnifying Party. The Indemnified Party may participate in, but not
control, any defense or settlement of any Third Party Claim controlled by the
Indemnifying Party pursuant to this Section 7.04(c) and will bear its own costs
and expenses with respect to that participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnified Party has
been advised by counsel that there may be one or more legal defenses a different
from or additional to those available to the Indemnifying Party, then the
Indemnified Party may employ separate counsel at the expense of the Indemnifying
Party, and, on its written notification of that employment, the Indemnifying
Party shall not have the right to assume or continue the defense of such action
on behalf of the Indemnified Party.

          (d) If the Indemnifying Party (i) within the Election Period (A)
disputes its potential liability to the Indemnified Party under this Article
VII, (B) elects not to defend the Indemnified Party pursuant to Section 7.04(c)
or (C) fails to notify the Indemnified Party that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 7.04(c) or (ii) elects to
defend the Indemnified Party pursuant to Section 7.04(c) but fails diligently
and promptly to prosecute or settle the Third Party Claim, then the Indemnified
Party shall have the right to defend, at the sole cost and expense of the
Indemnifying Party (if the Indemnified Party is entitled to indemnification
hereunder), the Third Party Claim by all appropriate proceedings, which
proceedings shall be promptly and vigorously prosecuted by the Indemnified Party
to a final conclusion or settled.  The Indemnified Party shall have full control
of such defense and proceedings.  Notwithstanding the foregoing, if the
Indemnifying Party has delivered a written notice to the Indemnified Party to
the effect that the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article VII and if that dispute is resolved in
favor of the Indemnifying Party, the Indemnifying Party shall not be required to
bear the costs and expenses of the Indemnified Party's defense pursuant to this
Section 7.04 or of the Indemnifying Party's participation therein at the
Indemnified Party's request, and the Indemnified Party shall reimburse the
Indemnifying Party in full for all reasonable costs and expenses of such
litigation.  The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 7.04(d), and the Indemnifying Party shall bear its own costs and
expenses with respect to that participation.

          (e) In the event any Indemnified Party should have a claim against any
Indemnifying Party hereunder that does not involve a Third Party Claim, the
Indemnified Party shall transmit to the Indemnifying Party a written notice (the
"Indemnity Notice") describing in reasonable detail the nature of the claim, an
estimate of the amount of Damages attributable to that claim to the extent
feasible (which estimate shall not be conclusive of the final amount of that
claim) and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the Indemnified
Party within 15 days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes the claim specified by the Indemnified Party in the
Indemnity Notice, that claim shall be deemed a liability of the Indemnifying
Party

                                      -36-
<PAGE>
 
hereunder. If the Indemnifying Party has timely disputed that claim, as provided
above, that dispute shall be resolved by proceedings in an appropriate court of
competent jurisdiction if the parties do not reach a settlement of that dispute
within 30 days after notice of that dispute is given.

          (f) Payments of all amounts owing by an Indemnifying Party pursuant to
this Article VII relating to a Third Party Claim shall be made within 30 days
after the latest of (i) the settlement of that Third Party Claim, (ii) the
expiration of the period for appeal of a final adjudication of that Third Party
Claim or (iii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Party's liability to the Indemnified Party under this
Agreement in respect of that Third Party Claim.  Payments of all amounts owing
by an Indemnifying Party pursuant to Section 7.04(e) shall be made within 30
days after the later of (i) the expiration of the 30-day Indemnity Notice period
or (ii) the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

          Section 7.5.  Remedies Not Exclusive.  The remedies provided in this
                        ----------------------                                
Agreement shall not be exclusive of any other rights or remedies available to
any other party, either at law or in equity.

          Section 7.6.  Limitations on Indemnification. (a)  Notwithstanding
                        ------------------------------                        
the provisions of Section 7.02(a), neither the Company nor any of the
Stockholders shall be required to indemnify or hold harmless any of the ARS
Indemnified Parties on account of any ARS Indemnified Loss under Section
7.02(a), other than an ARS Indemnified Loss under Section 7.02(a)(iii), unless
the liability of the Company and the Stockholders in respect of that ARS
Indemnified Loss, when aggregated with the liability of the Company and the
Stockholders in respect of all ARS Indemnified Losses under Section 7.02(a),
other than an ARS Indemnified Loss under Section 7.02(a)(iii), exceeds, and only
to the extent the aggregate amount of all those ARS Indemnified Losses does
exceed, the Threshold Amount.  In no event shall (i) the aggregate joint and
several liability of the Company and the Stockholders under this Agreement,
including Section 7.02(a), exceed the Ceiling Amount or  (ii) the aggregate
liability of each Stockholder under this Agreement, including Sections 7.02(a)
and 7.02(b), exceed that Stockholder's Pro Rata Share of the Ceiling Amount.
Any ARS Indemnified Loss under Section 7.02(a)(iii) shall be indemnified in full
(whether or not disclosed on any schedule attached to this agreement or
otherwise), subject to the Ceiling Amount limitations set forth in the preceding
sentence, and shall be excluded from ARS Indemnified Losses for purposes of
determining if the ARS Indemnified Losses under Section 7.02(a) exceed the
Threshold Amount.  For purposes of determining the amount of ARS Indemnified
Losses, no effect will be given to any resulting Tax benefit to any ARS
Indemnified Party.

          (b) Notwithstanding the provisions of Section 7.03, ARS shall not be
required to indemnify or hold harmless any of the Stockholder Indemnified
Parties on account of any Stockholder Indemnified Loss unless the liability of
ARS in respect of that Stockholder Indemnified Loss, when aggregated with the
liability of ARS in respect of all Stockholder

                                      -37-
<PAGE>
 
Indemnified Losses, exceeds, and only to the extent the aggregate amount of all
those Stockholder Indemnified Losses does exceed, the Threshold Amount. In no
event shall ARS be liable under this Agreement, including Section 7.04, for any
amount in excess of the Ceiling Amount. For purposes of determining the amount
of Stockholder Indemnified Losses, no effect will be given to any resulting Tax
benefit to any Stockholder Indemnified Party.

severally and not jointly with any other Person, that he will not, during the
period beginning on the date hereof and ending on the third anniversary of the
Closing Date, directly or indirectly, for any reason, for his own account or on
behalf of or together with any other Person:

          (a) engage as a director, officer or in any similar managerial
     capacity or as an owner, co-owner, financier or other investor of or in any
     business selling any products or providing any services in competition with
     the Acquired Business or ARS or any Subsidiary of ARS (ARS and its
     Subsidiaries collectively being "ARS" for purposes of this Article VIII)
     within any Territory surrounding any service facility in which the Acquired
     Business was engaged in business on the date hereof or immediately prior to
     the Effective Date (for purposes of this Article VIII, the "Territory"
     surrounding any service facility will be (i) the city,  town or village in
     which that service facility is located, (ii) the county or parish in which
     that service facility is located, (iii) the counties or parishes contiguous
     to the county or parish in which that service facility is located, (iv) the
     area located within 50 miles of that service facility, (v) the area located
     within 100 miles of that service area and (vi) the area in which that
     service facility regularly provides services at the locations of its
     customers);

          (b) call on any natural person who is at that time employed by the
     Acquired Business or ARS in any managerial capacity with the purpose or
     intent of attracting that person from the employ of the Acquired Business
     or ARS, provided that the Stockholder may call on and hire any of his
     family members;

          (c) call on, solicit or perform services for, either directly or
     indirectly, any Person that at that time is, or at any time within one year
     prior to that time was, a customer of the Acquired Business or ARS or any
     prospective customer that had or, to the knowledge of the Stockholder, was
     about to receive a business proposal from ARS, in any case within any
     Territory (i) for the purpose of soliciting or selling any product or
     service in competition with the Acquired Business or ARS in that Territory
     and (ii) with the knowledge of that customer relationship; or

          (d) call on any Entity which has been called on by ARS in connection
     with a possible acquisition by ARS, with the knowledge of that Entity's
     status as such an acquisition candidate, for the purpose of acquiring that
     Entity or arranging the acquisition of that Entity by any Person other than
     ARS.

Notwithstanding the foregoing, any Stockholder may own and hold as a passive
investment up to 5% of the outstanding capital stock of a competing Entity if
that class of capital stock is listed on a national stock exchange or included
in the Nasdaq National Market.

          Section 8.2.  Damages.  Because of the difficulty of measuring
                        -------                                         
economic losses to ARS as a result of any breach by a Stockholder of his
covenants in Section 8.01, and because of the immediate and irreparable damage
that could be caused to ARS for which it would have no other adequate remedy,
each Stockholder agrees that ARS may enforce the provisions of Section 8.01 by
injunctions and restraining orders against that Stockholder if he breaches any
of those provisions.

          Section 8.3.  Reasonable Restraint.  The parties hereto each agree
                        --------------------                                
that Sections 8.01 and 8.02 impose a reasonable restraint on the Stockholders in
light of the activities and business of ARS on the date hereof, the current
business plans of ARS and the investment, if any, by each Stockholder in ARS as
a result of the Acquisition.

          Section 8.4.  Severability; Reformation.  The covenants in this
                        -------------------------                        
Article VIII are severable and separate, and the unenforceability of any
specific covenant in this Article VIII is not intended by any party hereto to,
and shall not, affect the provisions of any other covenant in this Article VIII.
If any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth in Section 8.01 are unreasonable as applied
to any Stockholder, the parties hereto, including that Stockholder, acknowledge
their mutual intention and agreement that those restrictions be enforced to the
fullest extent the court deems reasonable, and thereby shall be reformed to that
extent as applied to that Stockholder and any other Stockholder similarly
situated.

          Section 8.5.  Independent Covenant.  All the covenants in this Article
                        --------------------                                    
VIII are intended by each party hereto to, and shall, be construed as an
agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of any Stockholder against ARS,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by ARS of any covenant in this Article VIII.  It is
specifically agreed that the period specified in Section 8.01 shall be computed
in the case of each Stockholder by excluding from that computation any time
during which that Stockholder is in violation of any provision of Section 8.01.
The covenants contained in this Article VIII shall not be affected by any breach
of any other provision hereof by any party hereto.

          Section 8.6.  Materiality.  The Company and each Stockholder,

VIII is a material and substantial part of the transactions contemplated hereby.

Company and the Stockholders, severally and not jointly with any other Person,
acknowledges that it has or may have had in the past, currently has and in the

Stockholders, severally and not jointly with any other Person, agrees that it
will keep confidential all such Confidential Information furnished to it and,
except with the specific prior written consent of ARS, will not disclose such
Confidential Information to any Person except (a) Representatives of ARS and (b)
its own Representatives, provided that these Representatives (other than
counsel) agree to the confidentiality provisions of this Section 10.01;
provided, however, that Confidential Information shall not include such
information as (i) becomes known to the public generally through no fault of any
Stockholder, (ii) is required to be disclosed by law or the order of any
Governmental Authority under color of law, provided, that prior to disclosing
any information pursuant to this clause (ii), each Stockholder shall, if

believes is required to be disclosed in connection with the defense of a lawsuit
against the disclosing party. In the event of a breach or threatened breach by
any Stockholder of the provisions of this Section 10.01 with respect to any
Confidential Information, ARS shall be entitled to an injunction restraining
such Stockholder from disclosing, in whole or in part, that Confidential
Information. Nothing herein shall be construed as prohibiting ARS from pursuing
any other available remedy for such breach or threatened breach, including the
recovery of damages.

Stockholders entitled to receive at least 80% of the total Acquisition
Consideration, the Company and ARS; provided, however, that no such amendment,
modification, supplement or waiver will be effective unless it is signed by each

(b) reduces the amount, or changes the components, of the Acquisition
Consideration that Stockholder is entitled to receive pursuant to Section 1.4,

to be performed or adhered to by it prior to or on the Closing Date;

          (c)  by the Stockholders or the Company, on the one hand, or by ARS,

observance or in the due and timely performance of any of the covenants,
agreements or conditions contained herein; or

          (d)  by ARS if it is entitled to do so as provided in Section 4.07.
