amount thereof, provided that Purchaser may dispute such Assumed Liability

II.3 The Closing. Subject to the terms and conditions of this
Agreement, the Closing shall take place at the New York offices of ▇▇▇▇▇,
Day, ▇▇▇▇▇▇ & ▇▇▇▇▇, commencing at 9:00 a.m., New York City time, on the
later of (a) December 31, 1998 and (b) the last business day of the first
month during which the satisfaction or waiver of all the conditions set forth
in Articles VIII and IX occurs (or at such other time and/or place and/or on
such other date as the parties may mutually agree) (the "Closing Date").

II.4 Purchase Price and Payment. The aggregate purchase price to
be paid by Purchaser under this Agreement (the "Purchase Price") shall
consist of cash in the amount of $29,000,000 subject to adjustment, as
provided in Section 2.5(e) hereof (the "Purchase Price Adjustment"). Payment
of the Purchase Price (excluding the amount of the Purchase Price Adjustment,
which shall be paid in accordance with Section 2.5(f) hereof) shall be made
no later than 12:00 noon, New York City time, on the Closing Date by wire
transfer in immediately available funds to the account of Bayer specified by
it at least two (2) business days prior to the Closing.

II.5 Purchase Price Adjustment. (a) Promptly after the Closing,
Bayer, with the cooperation of Purchaser, shall prepare schedules (the
"Proposed Closing Net Assets Schedule") setting forth (x) those Assets
constituting total assets ("Total Assets") and those Assumed Liabilities
constituting total liabilities ("Total Liabilities"), in each case as of the
Closing Date, and (y) Closing Net Assets. For purposes of this Agreement,

(i) the Proposed Closing Net Assets Schedule and the Final Closing Net Assets
Schedule shall be prepared (and Total Assets and Total Liabilities shall be
calculated) in accordance with the accounting procedures and policies
followed in preparing the Financial Statements referred to in Section 3.1,
(ii) the term "Total Assets" shall include those assets set forth on
Exhibit 2.5(a), and (iii) the term "Total Liabilities" shall include those
liabilities set forth on Exhibit 2.5(a). Bayer shall consult with Purchaser in
connection with the preparation of the Proposed Closing Net Assets Schedule and
shall have access to the records and working papers of the Business to the
extent necessary to prepare the Proposed Closing Net Assets Schedule. As
promptly as practicable, but no later than sixty (60 days) after closing, Bayer
shall deliver its Proposed Closing Net Assets Scedule to Purchaser.

(b) Within thirty (30) days after delivery of the Proposed Closing
Net Assets Schedule, the parties shall attempt to resolve any items or
amounts of Total Assets or Total Liabilities as to which Purchaser objects
(the "Disputed Items"). Any specific individual discrepancy which amounts to
two thousand five hundred dollars ($2,500) or less shall not be included as a
Disputed Item, and the aggregate of all Disputed Items must exceed twenty-
five thousand dollars ($25,000) before the procedures set forth in Section
2.5(c) hereof will be instituted.

(c) If during such thirty (30) day period any such Disputed Items
cannot be resolved, (i) those items to the extent of the amounts agreed upon
by the parties shall no longer constitute Disputed Items and shall be
conclusive for purposes of preparing the Final Closing Net Assets Schedule
and calculation of Closing Net Assets and (ii) the parties shall promptly
thereafter, but in no event more than ten (10) days thereafter, cause an
independent accounting firm of internationally recognized standing reasonably
satisfactory to Bayer and Purchaser promptly to review the remaining Disputed
Items for purposes of resolving such Disputed Items. Such accounting firm
shall make a determination only of Disputed Items not resolved by the
parties. Such accounting firm shall deliver to Bayer and Purchaser, as
promptly as practicable, a report setting forth its resolution of the
remaining Disputed Items. Such report shall be final and binding upon the
parties hereto and shall be conclusive for purposes of calculating Closing
Net Assets. The cost of such review and report shall be borne by the party
against whom the disagreement is in greater part resolved or, if the
resolution does not favor either party, such costs shall be borne equally by
Bayer and Purchaser. Each party agrees not to select the other party's
primary accounting firm to review Disputed Items pursuant to this Section
2.5(c).

(d) Closing Net Assets agreed to by the parties or as calculated
following resolution of all Disputed Items pursuant to Section 2.5(c) above,
as the case may be, shall be the "Final Closing Net Assets," and the Proposed
Closing Net Assets Schedule, adjusted to reflect Final Closing Net Assets,
shall be the "Final Closing Net Assets Schedule," which shall be conclusive
for all purposes of this Agreement. The determination of Final Closing Net
Assets shall represent the resolution of both the amount of Closing Net
Assets and the effect of Closing Net Assets on the Financial Statements for
all purposes of this Agreement, including any claims made for indemnification
pursuant to Section 12.2 hereof.

(e) If the amount of Final Closing Net Assets exceeds Nine Million
Thirty-Five Thousand dollars ($9,035,000), Purchaser shall promptly pay to
(or as directed by) Bayer the amount of such excess. If the amount of Final
Closing Net Assets is less than Nine Million Thirty-Five Thousand dollars
($9,035,000), Bayer shall promptly pay to (or as directed by) Purchaser the
amount of such deficit. Any such payment pursuant to this Section 2.5(e)
shall be made within ten (10) days after (i) Purchaser and Bayer agree upon
Final Closing Net Assets pursuant to Section 2.5(d) or (ii) if Disputed Items
are referred to a firm of independent accountants pursuant to Section 2.5(c),
the delivery of the report of such firm referred to in Section 2.5(c).

(f) Any payments pursuant to this Section 2.5 shall be made by
wire transfer of immediately available funds to such account of Bayer as
Bayer specifies, or Purchaser as Purchaser specifies, as applicable, at least
two (2) business days prior to the date of such payment. The amount of the
payment to be made pursuant to this Section 2.5 shall bear interest from and
including the date on which Bayer delivers to Purchaser the Proposed Closing
Net Assets Schedule to but excluding the date of payment at a rate per annum
equal to the three (3) month London Interbank Offered Rate as published in
The Wall Street Journal for the Closing Date. Such interest shall be payable
at the same time as the payment to which it relates and shall be calculated
daily on the basis of a year of three hundred sixty-five (365) days and the
actual number of days for which due.

II.6 Purchase Price Allocation. The parties shall allocate the
Purchase Price (as may be adjusted pursuant to Section 2.5) and the
assumption of the Assumed Liabilities among the Assets and the agreements
contained in Sections 7.1 and 7.2 hereof in a manner reasonably determined by
the parties and consistent with Section 1060 of the Code (the "Purchase Price
Allocation"). Bayer and Purchaser shall timely file with the IRS a Form 8594
consistent with the allocations determined by the parties. Bayer and
Purchaser shall report the transfer of the Assets in a manner consistent with
the Purchase Price Allocation and such form 8594 for all federal state, local
and foreign Tax purposes.

COVENANTS OF PURCHASER

Purchaser hereby covenants and agrees with Bayer as follows:

VI.1 Cooperation by Purchaser. (a) From the date hereof and
prior to the Closing, Purchaser will use its reasonable best efforts and will
cooperate with Bayer, to promptly secure all necessary consents, approvals,
authorizations, exemptions and waivers from third parties, including without
limitation, under the HSR Act and the antitrust laws and regulations of any
applicable non-United States jurisdictions, as shall be required in order to
enable Purchaser to promptly effect the transactions contemplated hereby, and
will otherwise use its reasonable best efforts to cause the prompt
consummation of such transactions in accordance with the terms and conditions
hereof. Purchaser shall cooperate with Bayer such that initial filings
required to be made pursuant to the HSR Act in connection with the
transactions contemplated hereby will be made no later than December 1, 1998.

(b) In connection with the foregoing, Purchaser shall use its
reasonable best efforts to resolve objections, if any, as may be asserted
with respect to the transactions contemplated hereby under any antitrust or
trade or regulatory laws or regulations of any Governmental Authority.

VI.2 Books and Records; Personnel. For a period of seven (7)
years from the Closing Date:

(a) Purchaser shall not dispose of or destroy any of the Books and
Records that may be relevant to Bayer without first offering to turn over
possession thereof to Bayer, at Bayer's cost, by written notice to Bayer at
least thirty (30) days prior to the proposed date of such disposition or
destruction.

(b) Purchaser shall allow Bayer and its agents reasonable access
to all Books and Records in Purchaser's possession and not in Bayer's
possession upon prior written notice during normal working hours at the
principal place of business of the Business or at any location where any
Books and Records are stored, and Bayer shall have the right, at its own
expense, to make copies of any such Books and Records; provided, however,
that any such access or copying shall be had or done in such a manner so as
not to unduly interfere with the normal conduct of Purchaser's business, and
provided further that (i) if disclosure of any information contained in the
Books and Records is compelled by legal process, and such information is not
publicly available and disclosure thereof would adversely affect Purchaser,
Purchaser shall have the right to contest the disclosure of such information
(which it shall do promptly and with diligence or it shall forfeit such
right) and shall indemnify Bayer and its Affiliates and hold them harmless
against any Losses incurred by any of them by reason of the non-disclosure of
such information, and (ii) if disclosure of any such information is not
compelled by legal process, Purchaser shall first have the opportunity to
require Bayer not to disclose such information by agreeing in writing, in
form and substance reasonably satisfactory to Bayer, to assume any liability
occasioning Bayer's request or otherwise to indemnify Bayer and its
Affiliates and hold them harmless against any Losses incurred by any of them
by reason of such non-disclosure.

(c) Purchaser shall make available to Bayer upon written request
(i) copies of any Books and Records, (ii) Purchaser's personnel to assist
Bayer in locating and obtaining any Books and Records, and (iii) any of
Purchaser's personnel whose assistance or participation is reasonably
required by Bayer or any of its Affiliates in anticipation of, or preparation
for, existing or future Litigation or other matters in which Bayer or any of
its Affiliates is involved. In addition, Purchaser shall otherwise cooperate
with any reasonable request of Bayer in connection with the performance,
defense or discharge of the Retained Liabilities. Bayer shall reimburse
Purchaser for the reasonable out-of-pocket expenses incurred by it in
performing the covenants contained in this Section 6.2(c).

VI.3 Further Assurances. At any time or from time to time after
the Closing, Purchaser shall, at the request of Bayer, execute and deliver
any further instruments or documents and take all such further action as
Bayer may reasonably request in order to accomplish the consummation of the
transactions contemplated hereby.

ARTICLE VII

ADDITIONAL AGREEMENTS

Bayer and Purchaser hereby covenant and agree with one another as
follows:

VII.1 Ancillary Agreements. Bayer and Purchaser shall execute and
deliver:

(a) a supply agreement in the form attached hereto as Exhibit 7.1
(a) (the "Bayer Supply Agreement"), providing for the supply by Bayer or its
Affiliates to Purchaser of specific products for resale;

(b) a supply agreement in the form attached hereto as Exhibit
7.1(b) (the "Purchaser Supply Agreement"), providing for the supply by
Purchaser to Bayer and its Affiliates of specific products; (c) a
transition services agreement in the form attached hereto as Exhibit
7.1(c) (the "Transition Services Agreement"); and

(d) a processing agreement in the form attached hereto as Exhibit 7.1(d)
(the "Processing Agreement").

VII.2 Covenant Not to Compete. (a) For the period ending on the third
(3rd) anniversary of the Closing Date, neither Bayer nor any Subsidiary or
Affiliate of Bayer, shall engage, in any geographical area in which the
Business currently does business, in the Business through the manufacture
(other than for Bayer's internal use), sale or distribution of any purified
animal blood protein product manufactured, sold or distributed for use in
diagnostic reagents or in culture media for the production of
biopharmaceuticals (other than pursuant to the Ancillary Agreements);
provided, however, that nothing contained herein shall preclude Bayer or any
Affiliate of Bayer from acquiring any interest in any business (the "Acquired
Business") some or all of the operations of which would otherwise violate the
foregoing prohibitions (the "Competing Operations") so long as (i) the annual
revenues attributable to the Competing Operations for its most recently
completed fiscal year exceed neither (x) ten percent (10%) of the annual
revenues of the Acquired Business nor (y) 100% of the annual revenues of the
Business, in each such case, such annual revenues to be the annual revenues
of the most recently completed fiscal year of the Acquired Business or the
Business, as the case may be, or (ii) if they do, the acquiring entity
divests itself of the Competing Operations as soon as practicable, but no
later than twelve (12) months, after such acquisition.

(b) For the period ending on the second (2nd) anniversary of the
Closing Date, neither Bayer nor any Subsidiary or Affiliate of Bayer shall
solicit any person who is an Employee (a "Restricted Employee") to leave the
employ of Purchaser or any of its Subsidiaries. Bayer or any of its
Subsidiaries may rehire any Restricted Employee upon the earlier to occur of
(i) the first (1st) anniversary of the date on which a Restricted Employee
voluntarily terminates his or her employment with Purchaser or (ii) the
second (2nd) anniversary of the Closing Date, and may rehire at any time a
Restricted Employee whose employment is involuntarily terminated by
Purchaser.

(c) Without intending to limit the remedies available to
Purchaser, Bayer agrees that damages at law would be an insufficient remedy
to Purchaser in the event of any breach by Bayer or any Subsidiary of Bayer
of this Section 7.2 and that Purchaser shall be entitled to injunctive relief
or other equitable remedies in the event of any such breach (without the
posting of a bond or other security).

(d) If any of the provisions of this Section 7.2 are held to be
unenforceable because of the scope, term or area of their applicability, then

the court making such determination shall modify such scope, term or area or
all of them to the extent necessary to render this Section 7.2 enforceable
under applicable law, and such provisions shall then be enforced in such
modified form.

(e) Notwithstanding the foregoing, from and after the Closing
Date, Bayer shall not use the names of Pentex or Ex-Cyte or any names similar
thereto or variants thereof or apply to use such names in any jurisdiction.

VII.3 Vehicle Leases. Bayer and Purchaser each covenant and agree
to use reasonable commercial efforts to amend, or cause to be amended, the
leases relating to the vehicles listed on Schedule 2.1(a)(ix) that are
currently leased to Bayer so as to cause Purchaser to become the lessee
thereof.

VII.4 Recall and Notification In the event of a product recall,
corrective action or any other customer notification arising due to a safety
or quality issue and related to products of the Business both (i)
manufactured by Bayer on or prior to the Closing and (ii) sold by Bayer on or
before the Closing Date or sold by Purchaser on or before the one hundred
fiftieth (150th) day after the Closing Date, Purchaser will administer and
perform such recall, corrective action or notification program, and Bayer
will reimburse Purchaser for Purchaser's reasonable, direct, out of pocket
costs and expenses related to such program on the condition that either (a)
such recall, corrective action or notification as performed was mandated by a
Governmental Authority, or (b) such recall, corrective action or
notification was administered and performed in consultation with and approved
in advance by Bayer.

VII.5 Securities Exchange Act Compliance. Bayer shall use its
reasonable efforts to assist Purchaser in preparing audited financial
statements of the Business in connection with the Purchaser's preparation and
filing of such reports as are required under the Securities Exchange Act of
1934 after the Closing. Bayer's efforts shall include, but are not limited
to, authorizing Bayer's accountants and allowing Bayer's personnel to assist
Purchaser, obtaining applicable representation letters and providing such
other cooperation and support as is reasonably necessary.

VII.6 Patent License. If and to the extent Purchaser is unable to
supply Bayer's quantities of cholesterol superstrate 82023 under the
Purchaser Supply Agreement, for a period of three (3) consecutive months,
then for the remaining life of the Patent, Purchaser hereby grants, and by
execution of this Agreement does grant, to Bayer and its Affiliates a non-
exclusive, royalty free, world wide license to make, have made and to use
internally products whose manufacture and/or use would otherwise infringe any
claim of the Patent, subject to the provisions of Section 7.2 hereof. The
provisions hereof shall survive the Closing.

VII.7 Confidentiality. (a) Except as otherwise provided in this
Section 7.7, each of the Purchaser, on the one hand, and Bayer, on the other
hand, shall keep confidential all information and records, whether written or
oral, which were obtained, directly or indirectly, form the other party
concerning the business of the other party ("Confidential Information") for a
period of five (5) years after the Closing Date. Prior to the Closing, each
of the Purchaser and Bayer shall use the Confidential Information solely in
connection with its analysis and review of the transactions contemplated by
this Agreement; provided, that upon and subsequent to the Closing all
Confidential Information included in the Assets or provided Purchaser by
Bayer under the Confidentiality Agreement shall be kept in confidence by
Bayer for a period of three (3) years after the Closing, and Purchaser shall
keep confidential in accordance with the terms of this Section 7.7 the
information and records obtained by Purchaser pursuant to Section 5.5, for a
period of five (5) years after the Closing.

(b) Each of Purchaser and Bayer may disclose Confidential
Information to any of its respective directors, officers, employees, agents,
financing sources, and advisors (each a "Representative" and, collectively,
the "Representatives") who need to know such Confidential Information, for
the purpose of assisting such party in connection with the transactions
contemplated by this Agreement; provided, however, that prior to making such
disclosure, such party shall inform each such Representative of the
provisions of this Section 7.7 and such party shall be responsible for any
breach of this Agreement by any such Representative. The Purchaser and Bayer
(the "Disclosing Party") may disclose Confidential Information if required by
legal process or by operation of applicable law; provided, however, that the
Disclosing Party shall first promptly advise and consult with the other party
(the "Subject Party") and its counsel concerning the information the
Disclosing Party proposes to disclose. The Subject Party shall have the
right to seek an appropriate protective order or other remedy concerning the
Confidential Information that the Disclosing Party proposes to disclose, and
the Disclosing Party will cooperate with the Subject Party to obtain such
protective order. In the event that such protective order or other remedy is
not obtained by the Subject Party, the Disclosing Party will disclose only
that portion of the Confidential Information which, the Disclosing Party is
legally required to disclose, and the Disclosing Party will use all
reasonable efforts to obtain assurances that confidential treatment will be
accorded to such information.

(c) The obligations of Purchaser and Bayer under this Section 7.7
do not apply to information which (i) at the time of disclosure is generally
available to and known by the public or within the industry other than as a
result of disclosure in violation of clause (a) or (b) of this Section 7.7 or
(ii) was or becomes available to a party on a non-confidential basis from a
source other than the other party or its agents or advisors; provided,
however, that such source is not bound by a confidentiality agreement or
obligation of secrecy in respect thereof.

(d) The obligations of Bayer hereunder shall not be construed to
limit Bayer's ability to reenter the Business after the expiration of the
covenant in Section 7.2.

(e) Each party acknowledges and agrees that any breach by it of
the provisions of this Section 7.7 will cause the other party irreparable
injury and damage, for which it cannot be adequately compensated in damages.
Each party, therefore, expressly agrees that the other party shall be
entitled to seek injunctive relief and/or other equitable relief to prevent
any anticipatory breach or continuing breach of the provisions of this
Section 7.7, or any part thereof, and to secure their enforcement.

VII.8 Environmental Matters On or prior to the Closing, Bayer
will engage a third party environmental consulting firm that is reasonably
acceptable to Purchaser to collect and analyze soil samples in the areas of

the Real Property where Bayer removed certain underground storage tanks in
1988 and where Bayer experienced a release in 1998. All costs incurred in
connection with the soil sampling and analysis described in this Section 7.8
shall be borne by Bayer. Purchaser and Bayer expressly acknowledge and agree
that Purchaser's receipt of the analytical results from the soil sampling
described in this Section 7.8 is not a condition of the Closing.

ARTICLE VIII

The obligations of Purchaser to purchase the Assets shall be
subject to the satisfaction (or waiver) on or prior to the Closing Date of

Bayer on or prior to the Closing Date, and the representations and warranties

representations and warranties of Bayer contained herein shall be true and
correct in all material respects as of the date when made and on and as of
the Closing Date with the same effect as though made on and as of the Closing
Date, except (a) where the failure to be true would not (after giving effect
to any adjustment with respect to Final Closing Net Assets Schedule) have a
Material Adverse Effect, except with respect to agreements, obligations,
covenants, representations or warranties which have been previously qualified
by Material Adverse Effect, (b) as otherwise contemplated hereby and (c) to
the extent that any such representations and warranties were made as of a
specified date which are qualified as to materiality or "Material Adverse
Effect" shall be true and correct as of the specified date and as to all
other such representations and warranties, the same shall have been true in
all material respects as of the specified date (except where the failure to
be true would not have a Material Adverse Effect). Purchaser shall have
received the Bayer Certificate.

encouraged any such action.

VIII.4 Documents. Purchaser shall have received the documents
referred to in Section 2.1(c).

Insurance Policy"), insuring that Purchaser is the fee-simple owner of the
Real Property free and clear of all Liens, except for Permitted Liens,
Mechanics' Liens and the matters listed on Exhibit 8.5 attached hereto. If,
prior to Closing, Purchaser obtains a survey that enables the Title Company
to delete the standard survey exceptions from the Title Policy, (an "Approved
Survey"), the term "Permitted Liens" shall also include matters that are
disclosed by such survey; provided, however, that the same do not render
title unmarketable or uninsurable. If, prior to the Closing, Purchaser does
not obtain an Approved Survey, then the term "Permitted Liens" shall also
include the standard survey exceptions and all other matters that would have
been disclosed by an accurate survey and inspection of the Real Property.

VIII.6 Material Adverse Changes No event has occurred which has
caused the Business, operations, assets, properties, or prospects of the
business to have been materially adversely affected as a result of any event
or occurrence.

ARTICLE X

EMPLOYMENT AND EMPLOYEE BENEFITS ARRANGEMENTS

X.1 Employment. Purchaser agrees to offer employment to all
Active Employees (as set forth on Exhibit 10.1 hereto) at a base salary or
wage rate that is initially not less than that provided by Bayer immediately
prior to closing. Purchaser agrees to offer employment to all Inactive
Employees (as set forth on Exhibit 10.1 hereto) when eligible to return to
active status, at a base salary or wage rate that is initially not less than
that provided by Bayer immediately prior to closing. Any and all liabilities
or expenses (i)relating to or arising out of the employment, or cessation of
the employment, of any Active or Inactive Employee on or prior to the Closing
Date or (ii) relating in any manner to employees of Bayer who are eligible
for long-term disability benefits as of the Closing Date will be the sole
responsibility of Bayer; provided, however, that Bayer's obligations with
respect to accrued but untaken vacation and variable holidays will be assumed
by Purchaser to the extent reflected in the Final Closing Net Assets
Schedule. Employees who are employed at locations outside of the United
States will be referred to herein as "Foreign Employees."

X.2 Collective Bargaining Agreement. If and when Purchaser
becomes a successor employer to Bayer under applicable law, it agrees, upon
the request of the bargaining unit, to recognize the bargaining unit as the
collective bargaining unit and negotiate in good faith.

X.3 Employee Benefit Plans.

(a) Purchaser agrees to provide Non Union Represented Employees
with salaries, wages, practices and benefits, which, in its sole discretion,
are generally comparable in the aggregate to the salaries, wages, practices
and benefits, in the aggregate, that they received as employees of Bayer
immediately prior to Closing. Purchaser agrees to provide coverage for
Foreign Employees under its employee benefit plans and programs and its
incentive compensation plans and programs that are offered to its similarly
situated employees employed in those countries. For a period of one year
following the Closing Date, Employees shall be given credit, without
duplication, for all service with Bayer or any Subsidiary or Affiliate of
Bayer (or service credited by Bayer or any Subsidiary or Affiliate of Bayer)
under (i) all employee benefit plans, programs and policies and fringe
benefits of Purchaser in which the Employees become participants for purposes
of eligibility and vesting and (ii) Purchaser's vacation, service award and
severance plans for purposes of calculating the amount of each Employee's
benefits under such plans. Furthermore, for a period of one year following
the Closing Date, Purchaser will maintain a vacation policy and holiday
schedule for the Employees that provides no less vacation than the current
Bayer policy applicable to the Transferred Employees.

(b) Effective as of the Closing Date, Purchaser shall cause its
qualified savings plan (the "Savings Plan") to accept any rollover
contribution that satisfies all applicable requirements of applicable law of
any cash distribution of account balances of Employees who were participants
in the Bayer Corporation Employee Savings Plan (the "Bayer Savings Plan").

(c) Purchaser shall waive any preexisting condition limitations
for such conditions covered under Bayer's medical, health or dental plans and
shall honor any deductible and out-of-pocket expenses incurred by Employees
and their dependents under Bayer's medical, dental or health plans during the
portion of the calendar year preceding the Closing Date. Purchaser shall
waive any medical certification under its group term life insurance plan for
any Employees up to the amount of coverage such Employee had under Bayer's
life insurance plan.

X.4 Severance. Without limiting the generality of the foregoing
provisions of this Article X, Purchaser agrees to provide severance pay and
other severance benefit entitlements which may be owing to each Employee
whose employment is terminated other than for cause by Purchaser or any
Affiliate within one (1) year after the Closing Date, and such severance pay
and severance benefit entitlements shall be determined (on an employee by
employee basis) in accordance with the severance policy of Bayer applicable
to such Employee as of the date hereof (copies of which have been furnished
to Purchaser).

X.5 Indemnity. Notwithstanding anything contained herein to the
contrary, Purchaser shall indemnify Bayer and its Affiliates and hold each of
them harmless from and against any Losses which may be incurred or suffered
by any of them (a) under the Worker Adjustment and Retraining Notification
Act arising out of, or relating to, any actions taken by Purchaser after the
Closing Date, (b) in connection with any claim made by any Employee for any
severance pay or termination pay or other severance benefit or termination

benefit entitlement by reason of any Employee's termination or deemed
termination of employment after the Closing Date for any reason, and (c) in
connection with any claim made by any Employee for wrongful termination,
discrimination or violation of any labor law arising out of facts which occur
after the Closing Date.

prior to the Closing:

(a) By the mutual written consent of Purchaser and Bayer; or

(b) By either Bayer or Purchaser in writing, without liability to
the terminating party on account of such termination (provided the
terminating party is not otherwise in default or in breach of this
Agreement), if the Closing shall not have occurred on or before March 31,
1999; or

(c) By either Bayer or Purchaser in writing, without liability to
the terminating party on account of such termination (provided the

that termination pursuant to clause (b) or (c) of Section 11.1 by reason of
breaches of covenants or agreements, or by reason of a breach by Purchaser of
its representations and warranties contained in Section 4.4 shall not relieve
the defaulting or breaching party from any liability to the other party
hereto.

(d) any product liability arising out of the manufacture, sale or

the Real Property or any off-site location or locations to which Bayer
transported or arranged for the transportation of Hazardous Substances
generated by Bayer during Bayer's operation of the Business, to the extent
arising directly or indirectly from acts, omissions, facts, circumstances,
events or conditions that occurred on or prior to the Closing Date. Bayer's

obligation to indemnify and hold Purchaser harmless as set forth in this
Section 12.2(g) shall terminate and end on the fifth anniversary of the
Closing unless a claim has been made prior thereto; or

(h) any Mechanics' Lien, but only to the extent that it relates to
(i) an obligation that is not an Assumed Liability and (ii) work, materials
or labor that does or do not relate to or arise out of the Project, which was
completed or were delivered prior to the Closing.

XII.3 Indemnification by Purchaser. Subject to Section 12.5, Purchaser shall
indemnify and hold harmless Bayer, its Affiliates, their respective officers,
directors, employees and agents from and against any and all Losses (net of
any Tax Benefits and insurance payments actually received in connection
therewith, less costs of collection) based upon or resulting from any of the

ownership of the Business by the Purchaser after the Closing and not relating
to any period prior to Closing other than Assumed Liabilities; or

(f) any liability or obligation relating to or arising out of the
Project, other than as a result of a breach of the representations in Section
3.28(a) hereof.

XII.4 Claims. When a party seeking indemnification under Sections
12.2 or 12.3 (the "Indemnified Party") receives notice of any claims made by
third parties (individually, a "Third Party Claim" and collectively, "Third
Party Claims") or has any other claim for indemnification other than a Third
Party Claim which is to be the basis for a claim for indemnification
hereunder, the Indemnified Party shall give prompt written notice thereof to
the other party (the "Indemnifying Party") reasonably indicating (to the
extent known) the nature of such claims and the basis thereof; provided,
however, that failure of the Indemnified Party to give the Indemnifying Party
prompt notice as provided herein shall not relieve the Indemnifying Party of
any of its obligations hereunder unless and only to the extent that the
Indemnifying Party shall have been prejudiced thereby. Upon notice from the
Indemnified Party, the Indemnifying Party may, but shall not be required to,
assume the defense of any such Third Party Claim, including its compromise or
settlement, and the Indemnifying Party shall pay all reasonable costs and

expenses thereof and shall be fully responsible for the outcome thereof;
provided, however, that in such case and except as specifically provided
below, the Indemnifying Party shall have no obligation to pay any further
costs or expenses of legal counsel of the Indemnified Party thereafter
incurred in connection with such defense other than reasonable costs of
investigation. No compromise or settlement in respect of any Third Party
Claims may be effected by the Indemnifying Party without the Indemnified
Party's prior written consent (which consent shall not be unreasonably
withheld), unless the sole relief is monetary damages that are paid in full
by the Indemnifying Party. The Indemnifying Party shall give notice to the
Indemnified Party as to its intention to assume the defense of any such Third
Party Claim within thirty (30) days after the date of receipt of the
Indemnified Party's notice in respect of such Third Party Claim. If the
Indemnifying Party does not, within thirty (30) days after the Indemnified
Party's notice is given, give notice to the Indemnified Party of its
assumption of the defense of the Third Party Claim, the Indemnifying Party
shall be deemed to have waived its rights to control the defense thereof. If
the Indemnified Party assumes the defense of any Third Party Claim because of
the failure of the Indemnifying Party to do so in accordance with this
Section 12.4, it may do so in such reasonable manner as it may deem
appropriate, and the Indemnifying Party shall pay all reasonable costs and
expenses of such defense as they are incurred. The Indemnifying Party shall
have no liability with respect to any compromise or settlement thereof
effected without its prior written consent (which consent shall not be
unreasonably withheld or delayed), unless the sole relief granted was
equitable relief for which it would have no liability or to which it would
not be subject. The Indemnified Party may participate in defense of a Third
Party Claim (which has been assumed by the Indemnifying Party) through the
Indemnified Party's own counsel, but at its own expense unless (i) the
employment of such counsel has been specifically authorized in writing by the
Indemnifying Party or (ii) the named parties in such Third Party Claim
include both the Indemnified Party and the Indemnifying Party and such
Indemnified Party has been advised in writing by its counsel that there may
be conflicting interests between the Indemnified Party and the Indemnifying
Party in the legal defense of such Third Party Claim. In connection with any
Environmental Matter, the party defending against the claim shall use all
reasonable efforts to obtain for the non-defending party any applicable
contribution protection.

XII.5 Limitations on Indemnification. (a) The provisions for
indemnity under Sections 12.2(a), 12.2(b), 12.2(g), 12.3(a) and 12.3(b), as
the case may be, shall be effective only when the aggregate amount of all
Losses for which indemnification is sought from Bayer or Purchaser under
Sections 12.2(a), 12.2(b), 12.2(g), 12.3(a) and 12.3(b), as the case may be,
exceeds one and one-half percent (1 1/2%) of the Purchase Price, in which
case the Indemnified Party shall be entitled to indemnification of its Losses
in an amount in excess of three quarters of one percent (.75%) of the
Purchase Price. The indemnification obligations of Indemnified Party's
Losses pursuant to Sections 12.2(a), 12.2(b), 12.2(g), 12.3(a) and 12.3(b),
as the case may be, shall be effective only until the dollar amount paid by
the Indemnifying Party in respect of the Losses indemnified against under
such Sections aggregates to twenty-five percent (25%) of the Purchase Price
("Indemnity Cap"); provided, however, that in no event shall more than
$2,000,000 of such Indemnity Cap be available for indemnification of Losses
related to any breach of the representations and warranties contained in
Section 3.28. The limitations set forth in Section 12.5 shall not apply to a
breach of the covenants in Sections 2.5(e) or (f).

(b) An Indemnifying Party shall not be liable for any individual
claim under Sections 12.2(a), 12.2(b), 12.2(g), 12.3(a) and 12.3(b) that does
not exceed Ten Thousand Dollars ($10,000).

(c) Each of the parties hereto acknowledges and agrees that, from
and after the Closing, its sole and exclusive remedy with respect to any and
all claims relating to the breach of representations, warranties and
covenants contained in this Agreement and in any Ancillary Document shall be
pursuant to the indemnification provisions set forth in this Article XII, in
Section 13.6, Section 10.5 and Section 2.2(c). In furtherance of the
foregoing, each of the parties hereto hereby waives, to the fullest extent
permitted under applicable law, any and all other rights, claims and causes
of action it may have, from and after the Closing, against the other party or
their respective officers, directors, employees, agents, representatives and
Affiliates arising from the breach of representations, warranties and
covenants contained in this Agreement and in any Ancillary Document. Each of
the parties hereto further acknowledges and agrees that the rights accorded
it under this Agreement are its sole and exclusive remedy with respect to any
Environmental Matters relating to the Business, and hereby waives and
releases any other claim, demand or cause of action it may now or in the
future have with respect to any such Environmental Matters, including without
limitation any such claim, demand or cause of action pursuant to any
Environmental Laws (as they have been or may in the future be in effect).

XII.6 Title Defects; Sole Remedy. Notwithstanding anything in
this Agreement to the contrary, if any breach of any covenant, warranty or
representation in this Agreement is caused by reason of the fact that the
Real Property, or any portion thereof, is subject to any lien or encumbrance
(other than a Curable Matter) which is not one of the Permitted Liens, the
sole remedy of Purchaser (i) with respect to any such failure or breach that
is discovered prior to the Closing, shall be to elect promptly either to
terminate this Agreement (but only if such failure or breach is material) or
to proceed with the Closing without any adjustment of the Purchase Price, in
which event the matter(s) which caused such breach shall be deemed for all
purposes to be included within the term "Permitted Liens" and (ii) with
respect to any such failure or breach that is discovered after the Closing,
shall be to pursue its remedies, if any, for breach of the limited warranty
in the Deed. The term "Curable Matter" means any lien created by Bayer in
connection with a monetary debt, but only if the exact amount of such debt
can be ascertained at the time of the Closing or any other lien or
encumbrance, the cure of which (A) can be accomplished prior to the Closing
Date, (B) is within the absolute control of Bayer and (C) will not require
Bayer to spend or incur any sum or obligation that is in excess of forty-five
thousand dollars ($45,000). At the Closing, Bayer shall use reasonable best
efforts to cure any matter that is a Curable Matter at or prior to the
Closing.

XII.7 Right to Contest Mechanics Liens. Notwithstanding anything
in this Agreement to the contrary, Bayer shall have the right, at its option,
to (a) contest (for so long as Bayer reasonably deems necessary) the
validity, amount and any other aspect of any Mechanics' Lien which Bayer, in
its reasonable judgment, determines should be contested and (b) provide a
bond, title insurance and any other relief which Bayer elects to provide with

respect to any Mechanics' Lien in order to mitigate any damages for which it
may be liable to Purchaser under Section 12.2(h) hereof.
