any violation or alleged or potential violation; provided, that to the extent
the representations contained in other sections of this Agreement address
compliance with specific Rules (including without limitation, representations

this SECTION 3.10 are qualified to the extent set forth in such other sections
of this Agreement. The Company holds and at all times has held all of the
material Permits necessary, desirable or useful for the current use, occupancy
or operation of the Business or ownership of the Assets, all of which are set
forth on Schedule 3.10. The Company is and at all times has been in full

                                       9
   15


REAL PROPERTY," and the improvements and fixtures thereon are hereinafter

              (b) Except as set forth on Schedule 3.11(a), the Company is the
sole legal and equitable owner of the leasehold interests in the Leased Real
Property and the Leased Improvements, free and clear of all Liens (other than

benefits of the rights provided to it under its lease of the Leased Real
Property and the Leased Improvements. The lease applicable to the Leased Real
Property is valid and in full force and effect and no event has occurred which
with the giving of notice or the passage of time or both could constitute a
default under such lease.

              (c) There are no adverse or other parties in possession of the
Leased Real Property, the Leased Improvements, or any portion or portions
thereof, and the leasehold interests in the Leased Real Property and the Leased

tenants except as set forth on Schedule 3.11(a). To the knowledge of the
Company, there are no pending or threatened condemnation, eminent domain or
similar proceedings, or litigation or other proceedings affecting the Leased
Real Property, the Leased Improvements or any portion or portions thereof. To
the knowledge of the Company, there are no pending or threatened requests,
applications or proceedings to alter or restrict any zoning or other use
restrictions applicable to the Leased Real Property or the Leased Improvements
that would interfere with the conduct of the Business, which interference would
have a Material Adverse Effect. Except as set forth on Schedule 3.11(a), all
water, sewer, gas, electric, telephone, drainage and other utility equipment,
facilities and services required by law or necessary for the operation of the
Leased Improvements are installed and connected, and no notice has been received

service. All equipment and fixtures associated with the Leased Improvements have
been properly maintained in accordance with industry standards and are in good
operating condition and repair. To the knowledge of the Company, all necessary
easements exist and are in full force and effect. The Leased Real Property has
access, in accordance with past practice, to and from a public right of way or

relating to the termination or impairment of such access (including applicable

furnished to Buyer (except for oral contracts, written descriptions in detail of
which have been previously furnished to Buyer). Each Material Contract is

by the Company, under any Material Contract. The Company has performed all
obligations required to



                                       10
   16

has occurred which with the giving of notice or the passage of time or both

instruments, purchase orders, relationships or commitments, written or oral,

         3.16 EMPLOYEE BENEFIT PLANS.

              (a) Except as set forth in Schedule 3.16, the Company has not

agreement, employment agreement, consulting agreement or any other benefit,
program or contract (collectively, "EMPLOYEE BENEFIT PLANS"), whether or not
written or pursuant to a collective bargaining agreement, which could give rise
to or result in the Company having any material debt, liability, claim or
obligation of any kind or nature, whether accrued, absolute, contingent, direct,
indirect, known or unknown, perfected or inchoate or otherwise and whether or
not due or to become due unless properly recorded on the Financial Statements or
unless such obligation or liability arose after the Closing Date Balance Sheet
Date in the ordinary course of business.

              (b) There has been no waiver (or application for a waiver) of the
minimum funding standards imposed by Section 412 of the Code with respect to any
Employee Benefit Plan other than any multi-employer plans, and there are no
facts or circumstances that would materially change the funded status of any
such Employee Benefit Plan other than any multi-employer plans. No asset of the
Company is subject to any lien under ERISA or the Code. The Company (i) has not
incurred any liability on account of a "partial withdrawal" or a "complete
withdrawal" (within the meaning of Sections 4205 and 4203, respectively, of
ERISA) from any Employee Benefit Plan subject to Title IV of ERISA which is a
"multi-employer plan" (as such term is defined in Section 3(37) of ERISA), and
no such liability has been asserted; and (ii) is not bound by any contract or
agreement or has any obligation or liability described in Section 4204 of ERISA.

              (c) Each Employee Benefit Plan other than any multi-employer plan
that is intended to be qualified under Section 401(a) of the Code has received a
determination from the Internal Revenue Service that such Employee Benefit Plan
is so qualified, and nothing has occurred since the date of such determination
that could adversely affect the qualified status of such Employee Benefit Plan.
No Employee Benefit Plan is a multi-employer plan or is subject to Title IV of
ERISA.

              (d) Each of the Employee Benefit Plans other than any
multi-employer plan and all related trusts, insurance contracts and funds have
been maintained, funded and administered in material compliance with their terms
and the terms of any applicable collective bargaining agreement, and in
compliance with the applicable provisions of ERISA, the Code, and any other
applicable laws. With respect to each Employee Benefit Plan, all required
payments, premiums, contributions, distributions, or reimbursements for all
periods ending prior to or as of the date hereof have been made or properly
accrued.

              (e) Neither the Company nor any other "disqualified person"
(within the meaning of Section 4975 of the Code) or any "party in interest"
(within the meaning of Section 3(14) of ERISA) has engaged in any "prohibited
transaction" (within the meaning of Section 4975 of the Code or Section 406 of
ERISA) with respect to any of the Employee Benefit Plans other than any
multi-employer plans which could subject any such Employee Benefit Plans, the
Company or any officer, director or employee of the Company to a penalty or tax
under Section 502(i) of ERISA or Section 4975 of the Code.



                                       13
   19


              (f) To the knowledge of the Company, other than any multi-employer
plan, each Employee Benefit Plan which is subject to the health care
continuation requirements of Part 6 of Subtitle B of Title I of ERISA or Section
4980B of the Code ("COBRA") has been administered in material compliance with
such requirements. No Employee Benefit Plan provides medical or life or other
welfare benefits to any current or future retired or terminated employee (or any
dependent thereof) of the Company other than as required pursuant to COBRA or
applicable state law.

              (g) With respect to each Employee Benefit Plan other than any
multi-employer plans, the Company has provided Buyer with true, complete and
correct copies of (to the extent applicable): (i) all documents pursuant to
which the Employee Benefit Plan is maintained, funded and administered
(including the plan and trust documents, any amendments thereto, the summary
plan descriptions, and any insurance contracts or service provider agreements);
(ii) the three most recent annual reports (IRS Form 5500 series) filed with the
Internal Revenue Service (with applicable attachments); and (iii) the most
recent determination letter, if any, received from the Internal Revenue Service.

              (h) The Company does not have any liability (or potential
liability, including potential liability under, because of another entity's
participation in a defined benefit plan or multi- employer plan) with respect to
any "employee benefit plan" (as defined in Section 3(3) of ERISA) solely by
reason of being treated as a single employer under Section 414 of the Code with
any trade, business or entity other than the Company.

         3.17 EMPLOYEES. Schedule 3.17 is a complete and correct list setting
forth (i) the names and current compensation rate and compensation of all
individuals presently employed by the Company on a salaried basis whose current
annual compensation is in excess of $25,000 and (ii) the names and total annual
compensation for all independent contractors who render services on a regular or
seasonal basis to the Company whose current annual compensation is in excess of
$25,000. Except as set forth on Schedule 3.17, no person listed thereon has
received any bonus or increase in compensation since and there has been no
"general increase" in the compensation or rate of compensation payable to any
such employees since the Closing Date Balance Sheet Date nor since such date has
there been any promise to the employees listed on Schedule 3.17, orally or in
writing, of any bonus or increase in compensation, whether or not legally
binding.

          (a) Indemnification by the Company and the Stockholders. Subject to
the indemnification limits described under subparagraph 6.4(h) below, from and

Affiliates and Plan Affiliates, and each of their respective officers,

liabilities, obligations, deficiencies, demands, claims, suits, actions, or
causes of action, assessments, losses, costs, expenses, interest, fines,

resulting from, arising out of or otherwise by virtue of any of the following:

              (i)   any misrepresentation or breach of a representation or
     warranty made herein or in the Company Transaction Documents by the
     Company;

                                       26
   32


              (ii)  any non-compliance with or breach by the Company of any of
     the covenants or agreements contained in this Agreement or the Company
     Transaction Documents to be performed by the Company;

              (iii) any liability or obligation of the Company or any assertion
     against a Buyer Indemnified Party, arising out of or relating, directly or
     indirectly, to any of the Excluded Liabilities; and

              (iv)  any claim for payment of fees and/or expenses as a broker or
     finder in connection with the origin, negotiation, execution or
     consummation of this Agreement based upon an alleged agreement between
     claimant and the Company or any of its Affiliates.

          (b) Indemnification by Buyer. From and after the Closing, Buyer agrees
to indemnify, defend and save the Company, its Affiliates, the Stockholders, and
the Company's officers, directors, employees, attorneys, agents and fiduciaries

promptly pay to a Company Indemnified Party or reimburse a Company Indemnified
Party for, any and all Losses sustained or incurred by any Company Indemnified
Party relating to, resulting from, arising out of or otherwise by virtue of any
of the following:

              (i)   any misrepresentation or breach of a representation or
     warranty made herein or in the Transaction Documents by Buyer;

              (ii)  non-compliance with or breach by Buyer of any of the

     or indirectly, to any of the Assumed Liabilities;

              (iv)  any claim for payment of fees and/or expenses as a broker or
     finder in connection with the origin, negotiation, execution or

     claimant and Buyer; and

              (v)   any obligation of Buyer arising out of the conduct of the
     Business after the Closing Date.

          (c) Indemnification Procedure for Third Party Claims. In the event
that subsequent to the Closing any person or entity entitled to indemnification
under this Agreement (an "INDEMNIFIED PARTY") receives notice of the assertion
of any claim or of the commencement

                                       27
   33


of any action or proceeding by any person or entity who is not a party to this
Agreement or an Affiliate of a party to this Agreement (including, but not
limited to, any domestic or foreign court or governmental authority, federal,
state or local) (a "THIRD PARTY CLAIM") against such Indemnified Party, against
which a party to this Agreement is required to provide indemnification under
this Agreement (an "INDEMNIFYING PARTY"), the Indemnified Party shall give
written notice together with a statement of any available information regarding
such claim (and attaching a copy of all papers served with respect to such
claim) to the Indemnifying Party within fifteen (15) days after learning of such
claim (or within such shorter time as may be necessary to give the Indemnifying
Party a reasonable opportunity to respond to such claim) (the "CLAIM NOTICE").
The Indemnifying Party shall have the right, upon written notice to the
Indemnified Party (the "DEFENSE NOTICE") within fifteen (15) days after receipt
from the Indemnified Party of notice of such claim, which notice by the
Indemnifying Party shall specify the counsel it will appoint to defend such
claim ("DEFENSE COUNSEL"), to conduct at its expense the defense against such
claim in its own name, or if necessary in the name of the Indemnified Party;
provided, however, that the Indemnified Party shall have the right to approve
the Defense Counsel, and in the event the Indemnifying Party and the Indemnified
Party cannot agree upon such counsel within ten (10) days after the Defense
Notice is provided, then the Indemnifying Party shall propose an alternate
Defense Counsel, which shall be subject again to the Indemnified Party's
approval, provided that the Indemnifying Party shall be entitled to take such
action as is reasonable under the circumstances to protect its rights pending
agreement upon the selection of Defense Counsel. Notwithstanding the foregoing,
the Indemnifying Party shall not be entitled to assume control of a Third Party
Claim and shall pay the reasonable fees and expenses of counsel retained by the
Indemnified Party if the Third Party Claim seeks injunctive or other equitable
relief or if the Indemnified Party, in the Claim Notice, states that, based on
advice of counsel, it believes that its interests in the Third Party Claims are
or can reasonably be expected to be adverse to the interests of Indemnifying
Party.

              (i)  In the event that the Indemnifying Party shall fail to give
     the Defense Notice within the time period described above, it shall be
     deemed to have elected not to conduct the defense of the subject claim, and
     in such event the Indemnified Party shall have the right to conduct such
     defense in good faith and to compromise and settle the claim without prior
     consent of the Indemnifying Party and such Indemnifying Party will be
     liable for all costs, expenses, settlement amounts or other Losses paid or
     incurred in connection therewith. If the Indemnifying Party is not entitled
     to assume the defense of a Third Party Claim because of reasons set forth
     in the last sentence of the preceding paragraph, the Indemnified Party may
     not settle the Third Party Claim without the written consent of the
     Indemnifying Party, which consent shall not be unreasonably withheld, if
     such settlement would lead to any liability or create any other obligation
     of the Indemnifying Party.

              (ii) In the event that the Indemnifying Party does deliver a
     Defense Notice within the time period described above and thereby elects to
     conduct the defense of the subject claim, the Indemnifying Party shall
     diligently conduct such defense and the Indemnified Party will cooperate
     with and make available to the Indemnifying Party such

                                       28
   34


     assistance and materials as it may reasonably request, all at the expense
     of the Indemnifying Party, and the Indemnified Party shall have the right
     at its expense to participate in the defense assisted by counsel of its own
     choosing.

              (iii) The Indemnifying Party may enter into any settlement of any
     Third Party Claim or cease to defend against such claim; provided, however,
     the Indemnifying Party may not enter into any settlement of any Third Party
     Claim or cease to defend against such claim without the prior written
     consent of the Indemnified Party if pursuant to or as a result of such
     settlement or cessation, (A) injunctive or other equitable relief would be
     imposed against the Indemnified Party, or (B) such settlement or cessation
     would lead to liability or create any financial or other obligation on the
     part of the Indemnified Party for which the Indemnified Party is not
     entitled to indemnification hereunder.

              (iv)  Any final judgment entered or settlement agreed upon in the
     manner provided herein shall be binding upon the Indemnifying Party, and
     shall conclusively be deemed to be an obligation with respect to which the
     Indemnified Party is entitled to prompt indemnification hereunder.

It is understood and agreed that if the Indemnifying Party is the Company and/or
the Stockholders collectively for purposes of this paragraph (c) the
Stockholders' Representative shall be the agent of such persons respect to the
matters arising hereunder in accordance with the provisions of SECTION 7.16.

          (d) Direct Claims. It is the intent of the parties hereto that all
direct claims by an Indemnified Party against a party hereto not arising out of
Third Party Claims shall be subject to and benefit from the terms of this
SECTION 6.4. Any claim under this SECTION 6.4 by an Indemnified Party for
indemnification other than indemnification against a Third Party Claim (a
"DIRECT CLAIM") will be asserted by giving the Indemnifying Party reasonably
prompt written notice thereof, and the Indemnifying Party will have a period of
thirty (30) calendar days within which to satisfy such Direct Claims, which
satisfaction shall, in the case of the Indemnifying Party being the Company and
the Stockholders, be in accordance with the offset provisions of SECTION 6.4(H).
If the Indemnifying Party disputes the Direct Claim asserted by the Indemnified
Party, such dispute shall be resolved in accordance with the provisions of
SECTION 7.8 herein. If the Indemnifying Party does not so respond within such
thirty (30) calendar day period, the Indemnifying Party will be deemed to have
rejected such claim, in which event the Indemnified Party will be free to pursue
such remedies as may be available to the Indemnified Party under this SECTION
6.4 or otherwise.

          (e) Failure to Give Timely Notice. A failure by an Indemnified Party
to give timely, complete or accurate notice as provided in SECTION 6.4(C) will
not affect the rights or obligations of any party hereunder except and only to
the extent that, as a result of such failure, any party entitled to receive such
notice was deprived of its right to recover any payment under

                                       29
   35


its applicable insurance coverage or was otherwise damaged as a result of such
failure to give timely notice.

          (f) Survival of Representations and Warranties: Time Limits on
Indemnification Obligations. All of the representations and warranties set forth
in this Agreement or in any of the other Transaction Documents shall survive the
execution and delivery of this Agreement and the consummation of the
transactions until they expire and terminate on the fourth (4th) anniversary of
this Agreement, except the representations and warranties contained in (i)
SECTION 3.1 (AUTHORITY), SECTION 3.2 (ORGANIZATION AND QUALIFICATION) and
SECTION 3.9(A) (TITLE TO ASSETS) shall survive indefinitely, (ii) SECTION 3.26
(TAXES) shall survive until thirty (30) days after the expiration of all
applicable statutes of limitations (including extensions of said statutes) and
(iii) SECTION 3.15 (INTELLECTUAL PROPERTY) shall survive until the third (3rd)
anniversary of the date of this Agreement. In the event Buyer incurs a Loss (or
asserts that a Loss may result from a contingent or unliquidated claim) and a
claim is filed, prior to the end of such applicable period, the termination date
shall be extended until such claim is fully resolved and Buyer appropriately
indemnified for such Loss.

          (g) Adjustment to Purchase Price. Any indemnification received under
SECTION 6.3 or this SECTION 6.4 shall be, to the extent permitted by law, an
adjustment to the Purchase Price.

          (h) Indemnification Limits. The foregoing provisions of this SECTION
6.4 notwithstanding:

              (i)  the Company and the Stockholders shall not be liable under
     the indemnification obligations set forth in SECTION 6.4(A)(I) of this
     Agreement until, and then only to the extent that, the aggregate amount of
     such indemnification obligation of the Company and the Stockholders exceeds
     $110,000 (the "BASKET AMOUNT"); provided, however, that the Basket Amount
     shall not apply to any indemnification arising under SECTION 6.4(A)(I) as a
     direct or indirect result of any fraudulent acts committed by the Company,
     or arising as a result of a breach of SECTION 3.7 (with regard to breaches
     relating to the Closing Date Balance Sheet), SECTION 3.9(A) (TITLE TO
     ASSETS), or SECTION 3.26 (TAXES);

              (ii) with respect to all indemnification obligations of the
     Company and the Stockholders other than for fraudulent acts committed by
     the Company or arising as a result of a breach of SECTION 3.1 (AUTHORITY),
     SECTION 3.2 (ORGANIZATION), SECTION 3.9(A) (TITLE TO ASSETS) and SECTION
     3.26 (TAXES) the aggregate indemnification obligation of the Company and
     the Stockholders shall not be greater than the remaining aggregate
     Quarterly Payments owed the Stockholders pursuant to SECTION 2.1(B) (the
     "CEILING AMOUNT") and the only source of recovery for such indemnification
     obligations shall be to withhold payment of and offset amounts due under
     the Notes severally payable to the



                                       30
   36


     Stockholders, which Buyer is hereby authorized to do, subject to the
     provisions of SECTION 7.8;

              (iii) the Ceiling Amount with respect to a breach of SECTION 3.15
     shall be, notwithstanding the provisions of subparagraph (ii) above,
     $4,500,000 (the "IP CEILING AMOUNT"), at all times during the three year
     period ending on the third anniversary date of the Closing Date except that
     the IP Ceiling Amount shall not apply with respect to a breach of SECTION
     3.15 resulting, directly or indirectly, from any fraudulent acts committed
     by the Company; and

              (iv)  Buyer shall not be liable under the indemnification
     obligations set forth in SECTION 6.4(B)(I) of this Agreement after the
     aggregate amount of such indemnification obligation of Buyer exceeds
     $4,500,000 (the "BUYER INDEMNIFICATION CEILING AMOUNT"); provided, however,
     that the Buyer Indemnification Ceiling Amount shall not apply to any
     indemnification arising under SECTION 6.4(B)(I) as a direct or indirect
     result of any fraudulent acts committed by Buyer.

     6.5  RESTRICTIVE COVENANTS.

          (a) Company's Acknowledgment. The Company agrees and acknowledges that
it is necessary that the Company undertake not to utilize its special knowledge
of the Business and its relationships with customers and suppliers of the
Company to compete with Buyer and the Company.

          (b) Non-Compete. The Company hereby agrees that for a period
commencing on the Closing Date and ending five (5) years from the Closing Date
(the "RESTRICTED PERIOD"), the Company will not, directly or indirectly, as
agent, consultant, stockholder, manager, partner or in any other capacity, own,
operate, manage, control, engage in, invest in or participate in any manner in,
act as a consultant or advisor to, render services for (alone or in association
with any Person), or otherwise assist any Person that engages in or owns,
invests in, operates, manages or controls any venture or enterprise that
directly or indirectly engages or proposes to engage in the Business anywhere in
the world (the "TERRITORY").

          (c) Non-Solicitation. Without limiting the generality of the
provisions of SECTION 6.5(B) above, the Company hereby agrees that during the
Restricted Period they will not, directly or indirectly, solicit, or participate
as agent, consultant, stockholder, manager, partner or in any other capacity in
any business which solicits, business from any Person which is or was a customer
or supplier of the Business during the three (3) year period preceding the date
of such solicitation, or from any successor in interest to any such Person for
the purpose of securing business or contracts related to the Business. In
addition, the Company hereby agrees that during the Restricted Period they will
not directly or indirectly buy or engage in any discussions with any acquisition
candidate with which the Company has engaged in discussions in the two (2) year
period preceding the Closing.


                                       31
   37


          (d) Confidential Information. During the term of this Agreement and
thereafter, the Company shall keep secret and retain in strictest confidence,
and shall not, without the prior written consent of Buyer, furnish, make
available or disclose to any third party or use for the benefit of the Company
or any third party, any Confidential Information. As used in this SECTION
6.5(D), "CONFIDENTIAL INFORMATION" shall mean any information relating to the
business or affairs of Buyer or the Business, and information relating to
financial statements, customer identities, potential customers, employees,
suppliers, servicing methods, equipment, programs, strategies and information,
analyses, profit margins or other proprietary information used by the Company or
the Buyer in connection with the Business; provided, however, that Confidential
Information shall not include any information which is in the public domain or
enters the public domain through no wrongful act on the part of the Company.

          (e) Interference with Relationships. During the Restricted Period, the
Company shall not, directly or indirectly, as agent, consultant, stockholder,
manager, partner or in any other capacity without the prior written consent of
Buyer employ, or engage, recruit or solicit for employment or engagement, any
person who is employed or engaged by the Company on the date hereof and who is
employed by the Buyer following the Closing, or otherwise seek to influence or
alter any such person's relationship with Buyer.

          (f) Blue-Pencil. If any court of competent jurisdiction shall at any
time deem the term of any particular restrictive covenant contained in this
SECTION 6.5 too lengthy or the Territory too extensive, the other provisions of
this SECTION 6.5 shall nevertheless stand, the Restricted Period shall be deemed
to be the longest period permissible by law under the circumstances and the
Territory shall be deemed to comprise the largest territory permissible by law
under the circumstances. The court in each case shall reduce the Restricted
Period and/or Territory to permissible duration or size.

          (g) Property of the Business. All memoranda, notes, lists, records and
other documentation or papers (and all copies thereof), including such items
stored in computer memories, or microfiche or by any other means, which will
become Buyer's property (after the consummation of transactions contemplated by
this Agreement), shall become Buyer's property and shall be delivered to Buyer
promptly on the request of Buyer.

          (h) Remedies. The Company acknowledges and agrees that the covenants
set forth in this SECTION 6.5 hereof are reasonable and necessary for the
protection of Buyer's business interests, that irreparable injury will result to
Buyer if the Company breaches any of the terms of this SECTION 6.5, and that in
the event of the Company's actual or threatened breach of any of the provisions
contained in this SECTION 6.5, Buyer will have no adequate remedy at law. The
Company accordingly agrees that in the event of any actual or threatened breach
by it of any of the provisions contained in this SECTION 6.5, Buyer shall be
entitled to such injunctive and other equitable relief, without the necessity of
showing actual monetary damages or posting of a bond, as may be deemed necessary
or appropriate by a court of competent jurisdiction. Nothing contained herein
shall be construed as prohibiting Buyer from pursuing any other remedies


                                       32
   38


available to them for such breach or threatened breach, including the recovery
of any damages which it is able to prove.

Closing, either (i) cease to use the name "THM Biomedical" and commence
dissolution proceedings, or (ii) change its legal name to a name dissimilar to
"THM Biomedical".

REPRESENTATIVE") with full power and authority to act as the representative,
agent and attorney-in-fact of each such Stockholder in connection with
fulfilling the obligations of such Stockholders under this Agreement and to
perform all acts required hereunder, including, but not limited to, (i) making
all decisions relating to the resolution and settlement of any disputes under
this Agreement, whether relating to such Stockholders' indemnification
obligations hereunder or otherwise, and, in connection therewith, without
limitation, receiving and delivering all notices, giving all approvals and
waivers, signing and entering into all agreements, releases, certificates and
instruments and exercising all rights of each such Stockholder in regard to his
rights and obligations under this Agreement, (ii) directing Buyer to pay funds
otherwise payable pursuant to the Notes delivered under SECTION 2.1, paragraph

duties hereunder; and (iii) taking in general all action which the Stockholders'
Representative, in his sole discretion, considers necessary or proper in
connection with or to carry out the transactions contemplated herein. Each of
the Stockholders signing this Agreement acknowledges and agrees that any payment

Representative or the Alternate Stockholders' Representative shall be binding
upon all of the Stockholders and no Stockholder shall have the right to object,
dissent from, protest or otherwise contest the same. The Buyer shall be
permitted to rely upon any written instrument or document executed by the
Stockholders' Representative or Alternative Stockholders' Representative. Buyer
agrees and acknowledges that the Stockholders' Representative, the Alternate
Stockholders' Representative and their respective affiliates shall have no
liability to Buyer for any act or omission in their capacity as the
Stockholders' Representative and the Alternate Stockholders' Representative.
Each Stockholder agrees and acknowledges that the Stockholders' Representative,
the Alternate Stockholders' Representative and their respective affiliates shall
have no liability to such Stockholder for any act or omission in their capacity
as the Stockholders' Representative and the Alternate Stockholders'
Representative except acts or omissions of the Stockholders' Representative or
the Alternate Stockholders' Representative which constitute gross negligence,
fraud or willful violation of law. To the extent Stockholders' Representative
requires funds to fulfill his obligations under this SECTION 7.16 in addition to
funds derived from Buyer's payment obligations under the Notes, each Stockholder
severally covenants to reimburse the Stockholders' Representative or the
Alternate Stockholders' Representative on demand for such Stockholder's pro rata
share (determined in proportion to the percentage of Company shares owned as
shown on Schedule 3.3) of all expenses incurred by the Stockholders'
Representative or the Alternate

                                       39
   45


Stockholders' Representative in the performance of his duties hereunder. The
Stockholders' Representative, the Alternate Stockholders' Representative and
their affiliates shall be and hereby are indemnified and held harmless by each
Stockholder from and against any and all claims, demands, liabilities, costs,
expenses, damages, losses, suits, proceedings and actions, whether judicial,
administrative, investigative or otherwise, of any nature whatsoever known or
unknown, liquidated or unliquidated, that may be asserted against the
Stockholders' Representative, the Alternate Stockholders' Representative or any
of their affiliates or in which any of such persons may become involved, as a
party or otherwise, arising out of the performance of the duties set forth in
this SECTION 7.16; provided, that, the maximum liability of any Stockholder
pursuant to this SECTION 7.16 to the Stockholders' Representative shall be
limited to and not exceed the portion of the Purchase Price payable to such
Stockholder less the amount paid to Buyer to fulfill the indemnification
obligation of such Stockholder pursuant to this Agreement (it being understood
that nothing in this SECTION 7.16 shall affect or diminish any Stockholder's
indemnification obligation to Buyer pursuant to this Agreement), provided
further, that, neither the Stockholders' Representatives, the Alternate
Stockholders' Representative nor any of their affiliates shall be entitled to
indemnification hereunder if it shall have been determined by a court of
competent jurisdiction or as part of a settlement that such person acted so as
to be liable for gross negligence, fraud or willful violation of law.

     7.17 GUARANTY. KNSY hereby unconditionally guarantees (the "GUARANTY") to
the Company and the Stockholders (collectively, the "BENEFICIARIES") the full
and complete performance and observance by Buyer of all covenants, conditions
and agreements contained in this Agreement to be performed and/or observed by
Buyer hereunder, including, without limitation, the obligations of Buyer to make
the Quarterly Payments pursuant to SECTION 2.1(B) (the "OBLIGATIONS"). The
undersigned further covenants and agrees that this Guaranty shall remain and
continue in full force and effect as to any amendment or modification of this
Agreement.

     KNSY hereby agrees that its liability under this Guaranty shall not be
affected or reduced by any agreement between the Beneficiaries and Buyer in
regard to the compromise, settlement, surrender, release, discharge, renewal,
extension, modification, amendment, alteration, subordination, or indulgence
with respect to or failure, neglect or omission to collect or enforce the
Obligations. KNSY hereby expressly waives diligence in collection or
prosecution, presentment, demand or protest or in giving notice to anyone of
protest, dishonor, default, or nonpayment or of the creation or existence of any
Obligation or of the acceptance of this Guaranty or any other matters or things
whatsoever relating to the Obligations. In their discretion, Beneficiaries may
proceed to collect any and all Obligations directly from KNSY without first
making demand upon Buyer.

     This is a continuing Guaranty and shall not be revoked by dissolution,
merger, bankruptcy or insolvency of KNSY with respect to all Obligations arising
prior to any such event. In the event that this Guaranty is revoked by KNSY,
said revocation shall have no effect on the continuing liability of KNSY to
guarantee unconditionally the prompt payment of all Obligations

                                       40
   46


which arose before the revocation became effective, including such prior
Obligations which were subsequently renewed, modified, or extended after the
revocation became effective. If KNSY shall become the subject of any bankruptcy
or insolvency proceedings, KNSY's liability hereunder to pay the Obligations
shall become immediately due and payable whether or not the Obligations are then
due and payable by the Buyer.

     This Guaranty shall inure to the benefit of the Beneficiaries, their
successors and assigns and shall be binding on the administrators, successors
and assigns of KNSY.

     Upon request, KNSY shall deliver a guaranty, substantially the same as the
foregoing, specifically applicable to each of the Notes.

                            [SIGNATURE PAGE FOLLOWS]
