ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

     As of August 19, 1999, Aberdeen Road Company, a Pennsylvania corporation
("Aberdeen"), purchased substantially all of the assets (the "Assets") and
assumed substantially all of the liabilities consisting of trade payables (the
"Liabilities") of Herculite Products, Inc., a New York corporation and Hercon
Environmental Corporation, a Delaware corporation (collectively the "Sellers"),
which are second and third-tier subsidiaries, respectively, of Health-Chem
Corporation (the "Company"), pursuant to an Asset Purchase Agreement dated as of
July 20, 1999 (the "Agreement").

     Under the terms of the Agreement, on the Closing Date Aberdeen (a) assumed
the Liabilities and (b) paid the purchase price (the "Purchase Price") of
$14,214,000 in cash on the Closing Date, of which $550,000 was placed in escrow
to secure the Sellers' and the Company's indemnification of Aberdeen as set
forth in the Agreement. The Purchase Price was determined as a result of
arm's-length negotiation between unrelated parties.

     Proceeds from the sale were used: 1) to repay in full the outstanding
indebtedness of the Company and its subsidiaries to their senior secured lender,
IBJ Whitehall Business Credit Corporation; 2) to make a $2 million distribution
of principal to holders of the Company's 10.375% Convertible Subordinated
Debentures (the "Debentures"); and 3) for expenses of the sale of the Assets and
related expenses; and the balance is to be used for working capital purposes.
The Debentures, in the approximate principal amount of $8 million plus accrued
interest, became due at their maturity on April 15, 1999.

     After the Closing, Paul R. Moeller and Steven Bernstein, two directors and
officers of the Company and certain of its subsidiaries, and Peter F. McKernan,
an officer of certain of the Company's subsidiaries, resigned all of their
positions with the Company and its subsidiaries and went into the full-time
employ of Aberdeen.

     The terms of the sale are more fully described in the Asset Purchase
Agreement, a copy of which is filed herewith as Exhibit 2.1 hereto.

     The sale of the Assets of the Sellers effects a divestiture of the
Company's synthetic fabrics and environmental products operations.

ITEM 7.   FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION
          AND EXHIBITS.

          (b)       Pro Forma Financial Information

          It is impractical to provide the required pro forma financial
information at the time of the filing of this report. The required pro forma
financial information will be filed by amendment to this Form 8-K no later than
60 days after September 3, 1999.

                                    ARTICLE I
                                PURCHASE AND SALE
                                -----------------

     Except as otherwise provided and subject to the terms and conditions set
forth in this Agreement, Sellers will sell, assign, transfer and deliver to
Buyer, and Buyer will purchase from Sellers at the Closing, all of Sellers'
right, title and interest in and to the Purchased Assets (as defined in Section

                                   ARTICLE II
                     DESCRIPTION OF ASSETS; EXCLUDED ASSETS
                     --------------------------------------

     Section 2.01   Purchased Assets. The assets to be conveyed to Buyer shall
include all of the assets of Sellers relating to the Business, whether tangible
or intangible, which relate in any way to the operation of the Business, (except
the Excluded Assets as defined in Section 2.02 hereof), and including, without
limitation: (a) the real property located on Aberdeen Road in Emigsville,

<PAGE>


Property of Sellers, including, but not limited to the "Herculite" and "Hercon"
trademarks and any variations thereof, the "Lure'n Kill" trademark and all brand
names or trade names now used by Sellers in connection with the sale of any of
their products, (e) all rights of Sellers under all Contracts listed on Schedule
2.01 and Contracts made in the ordinary course of business, involving the
Business to which either Seller is a party or by which either Seller has rights
(the "Purchased Contracts"), (f) all current and historical financial and
accounting records of the Business, and (g) all computer programs and software
used by Sellers in the Business (the "Software") (together, the "Purchased
Assets").

     Notwithstanding the aforesaid, for a period of seven (7) years following
the Closing, Buyer shall permit Sellers and its authorized agents and
representatives to visit its offices at reasonable times, to examine and make
copies of the financial and accounting records of the Business which are
included as part of the Purchased Assets.

     Additionally, on the Closing Date, Buyer shall grant a non-exclusive
royalty free license to (i) Herculite Products, Inc. solely to continue to use
the Herculite name in its corporate title (but not for any products) for a
period of ten (10) years, and (ii) to Hercon Laboratories Corporation and
Transderm Laboratories Corporation ("Transderm") to continue to use the Hercon
name in its corporate title and on its pharmaceutical, personal care and
cosmetic products. Notwithstanding the foregoing, in the case of Herculite the
license shall be nontransferable and in the case of Hercon an assignment of the
license shall be made only with Buyer's prior written approval, which approval
shall not be unreasonably withheld, provided, however, that such license may be
transferred as part of a sale of the business of Transderm and/or Hercon
Laboratories Corporation. Furthermore, on the Closing Date Buyer shall provide
Health-Chem and Transderm with a one year sub-license to use the Marcam

                                        4

<PAGE>


     Section 5.03   Allocation of Purchase Price. Sellers and Buyer agree that
of the total Purchase Price, (a) $5,000,000 shall be the amount paid for the
Real Property, (b) 90% of the remaining balance shall be the portion to be paid
for the Purchased Assets to be purchased from Herculite and (c) 10% of the
remaining balance shall be the portion to be paid for the Purchased Assets to be
purchased from Hercon. Buyer and Sellers each further agree to file their income
tax returns and their other tax returns and IRS Form 8594 reflecting the
allocations as determined in this Section 5.03.

     Section 5.04   Cash Purchase Price Adjustment. (a) As used in this Section
5.04, the following capitalized terms have the meanings set forth next to their
names:

     "Current Purchased Assets" means all of the Purchased Assets which would be
classified as current assets on Sellers' financial statements in accordance with
GAAP other than the Real Property.

     "Current Liabilities" has the meaning set forth in Section 3.01.

     "Net Operating Assets" means, at a given time, the difference calculated as
(i) Current Purchased Assets minus (ii) Current Liabilities other than
liabilities relating to the Real Property.

          (b)  Based on the information set forth in Sellers' April 30, 1999
balance sheet, the parties have negotiated the Cash Purchase Price, in part on
the basis that as of 12:01 a.m. of the Closing Date, Net Operating Assets of
Sellers will be $5,294,000.00 ("Projected Net Operating Assets"). If Net
Operating Assets, as of 12:01 a.m. of the Closing Date, are less or more than
Projected Net Operating Assets, the Base Price shall be adjusted downward or
upward, as applicable, on a dollar for dollar basis, by an amount equal to the
difference between Projected Net Operating Assets and Net Operating Assets of
Sellers at 12:01 a.m. of the Closing Date (the "Net Operating Assets
Adjustment").

          (c)  Additionally, the Cash Purchase Price shall be adjusted downward,
on the Closing Date, by an amount equal to the damage sustained by Buyer as a
consequence of any misrepresentation or breach of warranty made by Sellers
pursuant to this Agreement, but only to the extent that such damage exceeds
$250,000 (any such damage which does not exceed $250,000 shall, to the aggregate
extent thereof, be referred to herein as the "Non-Excess Damage"). There shall
be no further adjustment to the Cash Purchase Price in the event Buyer opts not
to purchase any or all assets classified under clause (c) in Section 2.01.

          (d)  Sellers shall prepare and submit to Buyer, not later than six (6)
Business Days prior to the Closing Date, a written good faith estimate of the
amount of the Net Operating Assets Adjustment in accordance with this Section
5.04 and Sellers' estimate of the Cash Purchase Price resulting from the Net
Operating Assets Adjustment ("Sellers' Estimate"). Sellers' Estimate shall be
accompanied by supporting documents, work papers, and other data supporting
Sellers' Estimate. The Sellers' Estimate shall be accompanied by a certificate
signed by an executive officer of Sellers certifying that the Sellers' Estimate
was calculated in good faith and in accordance with the provisions of this
Section 5.04. After the delivery of Sellers' Estimate and prior to the Closing,

                                        5

<PAGE>


Buyer and Sellers shall attempt to resolve any disputes between Buyer and
Sellers with respect to Sellers' Estimate. In connection therewith, Buyer shall
have full access to all Sellers' records related to Sellers' Estimate. Two (2)
Business Days prior to Closing, Buyer shall advise Sellers in writing as to any
dispute Buyer has with Sellers' Estimate, and provide Sellers with Buyer's
calculation of the Net Operating Assets Adjustment and the Cash Purchase Price,
accompanied by a certificate signed by an executive officer of Buyer certifying
that Buyer's calculation was made in good faith and supporting documents and
information, to the extent the same is available to Buyer ("Buyer's Estimate").
In the event Buyer's Estimate of the Cash Purchase Price is within $30,000 of
Sellers' Estimate, the Closing shall proceed with the Cash Purchase Price based
upon Sellers' Estimate less fifty percent (50%) of the difference between
Buyer's Estimate and Sellers' Estimate. In the event Buyer's Estimate of the
Cash Purchase Price is less than Sellers' Estimate by an amount in excess of
$30,000, the Closing shall proceed with the Cash Purchase Price based upon the
Sellers' Estimate made in good faith except that the lower of (i) $500,000 and
(ii) the difference between Buyer's Estimate and Sellers' Estimate of the Cash
Purchase Price (the "Estimate Difference") shall be delivered out of the Cash
Purchase Price by Buyer to the Escrow Agent, and not to the Sellers, to be held,
invested and disbursed pursuant to the terms of Escrow Agreement No. 1
substantially in the form of Exhibit E attached hereto ("Escrow Agreement No.
1").

     After the Closing, Buyer and Sellers shall use good faith efforts to
jointly resolve the Estimate Difference. If Buyer and Sellers cannot resolve the
Estimate Difference to their mutual satisfaction within five (5) Business Days
after Closing, then the matter shall be submitted to the Independent Accountants
(as defined in Section 5.05 below). The Independent Accountants shall resolve
the dispute substantially in accordance with the procedures set forth in Section
5.05 below and the decision of the Independent Accountants with respect to the
Net Operating Assets Adjustment shall be final and binding on the parties.

     Within five (5) Business Days of receipt of the Independent Accountants'
decision with respect to such dispute, if Buyer is determined to owe an amount
to Sellers, the Escrow Agent shall pay such amount to Sellers from Escrow No. 1,
and if Sellers are determined to owe an amount to Buyer, the Escrow Agent shall
pay such amount to Buyer from Escrow No. 1, in each case with the excess, if
any, paid over to the other party by the Escrow Agent. All amounts owed by Buyer
or Sellers to the other in accordance with this Section 5.04 shall be paid by
wire transfer of immediately available funds with interest earned.

     Section 5.05   Independent Accountants, Procedures. For the purposes of
this Agreement, the term "Independent Accountants" means the Montvale, New
Jersey office of KPMG LLP. The parties shall cooperate in making the fee
arrangement with that firm based on its estimate. In submitting a dispute to the
Independent Accountants, each of Sellers and Buyer shall furnish, at its own
expense, the Independent Accountants and the other party with such documents and
information as the Independent Accountants may reasonably request. Each party
may also furnish to the Independent Accountants such other information and
documents as it deems relevant with the appropriate copies and notification
being given to the other party. The Independent Accountants may conduct a
conference concerning the disagreements between Sellers and Buyer at which
conference each party shall have the right to present additional documents,
materials and other evidence and to have present its or their advisers,
accountants or counsel. The Independent

                                        6

<PAGE>


Accountants shall promptly render a decision on the issues presented, and such
decision shall be final and binding on the parties, provided, that such decision
may not be more than Sellers' Estimate or less than Buyer's Estimate. Fees and
expenses of the Independent Accountants relating to the matters provided for in
this Agreement shall be shared equally be the parties, unless a party's estimate
varies by more than twelve and one-half percent (12.5%) from the decision
reached by the Independent Accountants, in which case the fees and expenses of
the Independent Accountants shall be paid by such party. Notwithstanding the
foregoing, if each party's estimate varies by more than twelve and one-half
percent (12.5%) from the decision, the fees shall be shared equally by the
parties.

     Section 5.06   Indemnity and Older Inventory Escrow.

          (a)  At the Closing, Buyer and Sellers shall execute and deliver an
escrow agreement substantially in the form of Exhibit F hereto ("Escrow
Agreement No. 2"). Buyer shall deposit with the Escrow Agent $500,000 ("Escrow
Amount No. 2"), out of the Cash Purchase Price payable to the Sellers at the
Closing.

          (b)  Subject to the provisions of Escrow Agreement No. 2, Escrow
Amount No. 2 shall be available to satisfy (i) claims by Buyer for
indemnification under Section 14.02 and (ii)(A) performance of Sellers'
obligation to repurchase unsold Older Inventory and/or (B) payment to Buyer of
the difference between the Closing Date carrying value of the Older Inventory
and the actual price received by Buyer from sales of such Older Inventory, as
the case may be, in each case in accordance with Section 9.06. On the first
anniversary of the Closing Date, Escrow Amount No. 2 less all amounts required
for payment of claims made by Buyer pursuant to the terms of Escrow Agreement
No. 2, shall be paid to the Sellers, together with interest earned on the amount
to be released. Sellers are permitted to credit the amount of their repurchase
obligation under Section 9.06 against the portion of Escrow Amount No. 2 to be
released to Sellers. Notwithstanding the foregoing, if Sellers have not received
the tax clearance certificate described in Section 9.10 by the first anniversary
of the Closing Date, $100,000 of Escrow Amount No. 2 shall continue to be held
by the Escrow Agent until the tax clearance certificate is obtained. Upon
receipt of the tax clearance certificate, Buyer and Sellers shall direct the
Escrow Agent to release $100,000 to Sellers and/or to government agencies, if,
and to the extent required to be paid to a governmental agency in order to
obtain such tax clearance certificate.

     Section 5.07   Real Property Apportionments. At Closing, all real property
taxes shall be apportioned on a calendar year or fiscal year basis, as
appropriate, and sewer, water and trash collection bills, as applicable, shall
be apportioned pro rata between Buyer and Sellers on a per diem basis as of the
Closing Date. Utility meter readings shall be taken as of the Closing Date.
Buyer shall be responsible for all utility costs incurred on or after the
Closing Date.

     Section 7.14   Accounts Receivable and Bad Debts. To Sellers' knowledge,
except as set forth on Schedule 7.14, all of the existing accounts receivable of

made, or services actually performed in the ordinary course of its business.
Unless paid prior to Closing or set forth on Schedule 7.14, the accounts
receivable are current (less than 120 days) and collectible, in full, net of the
respective reserves shown on the April 30, 1999 Interim Statement or on the

payments it collects on receivables of a customer (irrespective of whether such
receivables arose before or after the Closing) against the oldest outstanding
receivables of such customer, irrespective of whether the oldest receivables are

is no contest, claim or right of set-off, other than returns in the ordinary
course of business, with respect to any of the accounts receivable.

do not owe any amount to, or have any contract with or commitment to, any
shareholder, director, officer, employee or consultant of Sellers (other than

due and payable, rent payable to an Affiliate, and reimbursement of expenses
arising in Sellers' ordinary course of business), and no such person owes any
amount of money to Sellers.

     Section 7.16   No Adverse Change. Since the Interim Financial Statement of
April 30, 1999, neither Seller has suffered any material adverse change in its
business, financial condition, operations, prospects or assets, nor has any

expected to have a material adverse affect on the business, financial condition,
operations, prospects or assets of either Seller.

any knowledge or reason to believe, that any customers whose purchases represent
three percent (3%) or more, either individually or in the aggregate, of sales

reduce their relationship with either Seller within the twelve (12) calendar

                          SELLERS'AND BUYER'S COVENANTS
                          -----------------------------

     Section 9.01   Third Party Consents; Closing Conditions.

          (a)  Buyer and Sellers covenant and agree that each of them will
reasonably cooperate with each other, and Buyer will do all things reasonably

Schedule 7.02, including the furnishing of financial and other information with
respect to Buyer, its Affiliates, or Sellers, as the case may be, reasonably
required by the Person whose consent or approval is being sought.
Notwithstanding the foregoing, to the extent that any Purchased Asset is not
capable of being sold, assigned, transferred or conveyed without the consent or
approval of any third Person, and such consent or approval has not been
obtained, this Agreement shall not constitute a sale, assignment, transfer or
conveyance thereof, or an attempted sale, assignment, transfer or conveyance
thereof, provided, however, Sellers shall use their commercially reasonable
efforts to provide Buyer the benefits of any such Purchased Asset as provided in
Section 20.01 and the Cash Purchase Price shall be reduced in an amount equal to
the fair market value of the Purchased Assets not transferred to Buyer.

          (b)  Buyer and Sellers hereby covenant and agree to use all
commercially reasonable efforts to satisfy, or assist the other party (or

such measurements, surveys, borings or tests on the Real Property as Buyer may
deem advisable. Sellers shall furnish Buyer with such information respecting the
Purchased Assets and Business and financial records as Buyer may, from time to
time, reasonably request. Buyer agrees to provide Sellers with prompt written
notice if Buyer determines that, based upon information provided to Buyer or
through its own investigation, Sellers are in breach of any representations,
warranty or covenant of Sellers set forth in this Agreement. Buyer hereby
indemnifies and holds harmless Sellers from any claims or liabilities, including
costs of defense and reasonable attorneys fees, arising out of the actions of

default under, or termination of (except in accordance with its terms), any
Material Contract to which either Seller is a party or by which either Seller is
bound and which is to be assumed by Buyer hereunder;

          (f)  notify Buyer in writing promptly after learning of the
institution or threat of any litigation against either Seller;

          (g)  pay or cause to be paid or provide for all Taxes of or relating

any of such Taxes, then Sellers shall pay such Taxes upon resolution of such
dispute in favor of the opposing party;

          (h)  subject to the provisions of Section 9.04 of this Agreement,

any of the foregoing.

     Section 9.04   Employees.

          (a)  Subject to subsection (h) of this Section 9.04, Buyer may, but
shall have no obligation to, offer employment to any of the current employees of
the Sellers pursuant to this Section 9.04(a). Not less than fourteen (14) days
prior to the Closing Date, Buyer will notify Sellers in writing which employees
will be offered employment by Buyer and setting forth the costs of compensation
("Buyer's List"). On the Closing Date, Buyer shall offer employment to all
employees of Sellers on Buyer's List at such rates, provided, however, that

Date the employment of any employee who

                                       19

<PAGE>


accepts such offer. Any such offers shall be at such salary or wage and benefit
levels and on such other terms and conditions as Buyer shall in its sole
discretion deem appropriate. The employees who accept and report for work with
Buyer as contemplated hereby are hereinafter collectively referred to as the
"Transferred Employees."

          (b)  Sellers shall retain any obligations and liabilities under the
Employee Benefit Plans in respect of each employee or former employee (including
any beneficiary or dependent thereof) who is not a Transferred Employee.

          (c)  With respect to the Transferred Employees (including any
beneficiary or dependent thereof), Sellers shall retain (i) all liabilities and
obligations arising under any group life, accident, medical, dental or
disability plan or similar arrangement to the extent that such liability or
obligation relates to contributions or premiums accrued or to claims incurred on
or prior to the Closing Date, (ii) all liabilities and obligations arising under
any worker's compensation arrangement to the extent such liability or obligation
relates to the period prior to the Closing Date and (iii) all other liabilities
and obligations arising under the Employee Benefit Plans to the extent any such
liability or obligation relates to the period prior to the Closing Date. Buyer
shall assume all other obligation of Sellers to Transferred Employees.

          (d)  Sellers shall, to the date of Closing, fully pay and fund all

plan or other similar arrangements, including severance or pension benefits
owing by either Seller under any union contract, workman's compensation
premiums, all FICA and FUTA taxes for all employees, all employee salary and
wage deferrals and all other employer obligations under Employee Benefit Plans
or any other contract or law to which Sellers are subject.

          (e)  Sellers shall be responsible, and Buyer shall have no
responsibility, for all severance obligations to all employees who do not become
Transferred Employees.

          (f)  No provision of this Section 9.04 shall create any third party
beneficiary or other rights in any employee or former employee (including any
beneficiary or dependent thereof) of Sellers or any of their Affiliates in
respect of continued employment (or resumed employment) with either Buyer,
Sellers or their respective Affiliates, and no provision of this Section 9.04
shall create any such rights in any such persons in respect of any benefits that
may be provided, directly or indirectly, under any Employee Benefit Plan or
other plan or arrangement or any plan or arrangement which may be established by
Buyer or any of its Affiliates.

          (g)  Sellers will not take any action to cause the aggregate number of
employees permanently laid off or fired in the ninety (90) days immediately
preceding the Closing to exceed fifteen (15) and the aggregate number of
employees temporarily laid off in the ninety (90) days immediately preceding the
Closing to exceed fifteen (15).

          (h)  Buyer shall hire within thirty (30) days after the Closing, at a
minimum, such number of individuals employed by Sellers immediately prior to the
Closing, in order to comply with WARN and to avoid, as a result of the Closing,
a mass layoff under WARN. Buyer waives

                                       20

<PAGE>

     Section 9.05   Supplemental Disclosure. Sellers shall have the right from
time to time prior to the Closing Date to supplement in writing the disclosure
schedules hereto with respect to any matter hereafter arising that, if existing
or known as of the date of this Agreement, would have been required to be set
forth or described in the disclosure schedules hereto, provided, however, no
such supplemental disclosure shall be deemed to cure any breach of any
representation or warranty of Sellers made in this Agreement unless Buyer fails
to object in writing to Sellers to any such supplemental disclosure within ten
(10) Business Days after Buyer's receipt thereof. In the event of Buyer's
failure to object, any breach of any representation or warranty shall be deemed
to be cured by such supplemental disclosure. Notwithstanding the foregoing, in
the event that Buyer fails to notify Sellers in writing of any of Buyer's
objections to title to the Real Property within the time period set forth in
Article X hereof, then (a) the Permitted Lien Schedule (referred to in the

inventory of Sellers which as of the Closing Date is one year old or more.
During the one year period following the Closing, Buyer shall use commercially
reasonable efforts to sell the Older Inventory at a price equal to the carrying

accept the best available price for the Older Inventory. On the first
anniversary of the Closing Date: (i) Buyer shall be entitled to receive, from
Escrow No. 2, the difference between the carrying value and the actual price
received by Buyer from sales of Older Inventory, and (ii) Sellers shall
repurchase all of the Older Inventory that has not been sold by Buyer during
such one year period. The purchase price for the Older Inventory shall be the
carrying value.

at reasonable times to access and copy records and consult with employees to the

by Section 9.10 hereof and to assist Sellers with respect to any claim made by a

Assets. Sellers' shall pay all out-of-pocket expenses incurred by Buyer in

commercially reasonable efforts to collect any outstanding accounts receivable

receivables of a customer (irrespective of whether such receivables arose before
or after the Closing) against the oldest outstanding receivables of such
customer, irrespective of whether the oldest receivables are contested by such
customer. After the 180th day following the Closing Date, to the extent Buyer
has not collected (or credited pursuant to the foregoing sentence) accounts
receivable which were outstanding on Sellers' financials as of the Closing Date,
Buyer may elect to have Sellers purchase such accounts receivables at a price
equal to the amount at which they were carried on Sellers' financials as of the
Closing Date, net of any reserves reflected in such financials.

     Section 9.10   Compliance with Bulk Sales Laws. Sellers and Buyer shall
comply with all applicable requirements of the Pennsylvania Fiscal Code, as
amended, relating to bulk transfers and shall comply with all applicable
requirements of the bulk sales provision of the Pennsylvania Tax Reform Code of
1971, as amended, in connection with the transactions contemplated by this
Agreement. Sellers shall indemnify Buyer from, and hold it harmless against, any
liabilities, damages, costs and expenses resulting from or arising out of (i)
Sellers' failure to comply with any of such laws with respect to the
transactions contemplated by this Agreement, including any untimely filing by
Sellers of a bulk sales notice as required by Pennsylvania law, or (ii) any
action brought or levy made as a result of the Sellers' failure to comply with
any of such laws, other than those liabilities which have been expressly
assumed, on such terms as expressly assumed, by the Buyer pursuant to this
Agreement. At the Closing each Seller shall deliver to the Buyer a request for a
tax clearance certificate, fully authorized and executed by the Seller and in
suitable form for purposes of filing with governmental authorities in accordance
with Pennsylvania law. Within five calendar days of receipt of a tax clearance
certificate in response to such request, a copy of the tax clearance certificate
received shall be delivered by Sellers to Buyer.

     Section 9.11   HSR Act Filings. Buyer and Sellers shall use all reasonable
efforts to file, within five (5) Business Days after the date of this Agreement,

Property, inspect the Real Property and take any other actions Buyer deems
reasonably necessary to determine the condition of title to the Real Property.
Within thirty (30) days after the date hereof, Buyer shall provide Sellers with
written notification of any objections to title, other than the Permitted Liens.
If Buyer does not notify Sellers of any objections to title within said thirty
(30) day period, Buyer shall be deemed to have waived its rights to object to

then Sellers shall have the right to cure

                                       22

<PAGE>


such objections. If Sellers elect not to cure the objections, Buyer shall have
the option to elect to either (i) proceed with this Agreement, waive its
objection to the title defect and purchase the Purchased Assets without
abatement in the Cash Purchase Price, or (ii) terminate this Agreement. If
Sellers elect to attempt to cure the title objection and are unable to cure the
title objection within thirty (30) days after Buyer notifies Sellers of such
title defect, Buyer shall have the right to either (y) waive its objection to
the title defect and purchase the Purchased Assets without abatement in the Cash
Purchase Price or (z) terminate this Agreement. Sellers shall not be required to
bring any action or proceeding in order to cure any such objections and shall
not be required to expend any money to cure any such objections, but the
foregoing shall not permit Sellers to refuse to pay at the Closing, to the
extent of the monies payable at the Closing, mortgages, deeds of trust or deeds
to secure debt encumbering the Real Property of which Sellers have actual
knowledge at Closing. Acceptance by Buyer at Closing of the Deed shall be deemed
to fully discharge Sellers of their obligations as to the quality of title to
the Real Property, except as otherwise set forth herein. Any encumbrance or
other matter of record other than a lien shall be a Permitted Lien unless it
would interfere with a continuation of the present use of the building on the
Real Property.

                          CASUALTY LOSSES; CONDEMNATION
                          -----------------------------

     Section 13.01  Casualty. (a) In the event that there shall have been
suffered between the date hereof and the Closing, any casualty loss relating to
the Purchased Assets or the Business, Sellers will promptly notify Buyer of such
event. If such casualty does not result in an inability to continue the

     Section 14.01  Survival. The representations, warranties, covenants, and
agreements made in this Agreement and in any agreement or instrument executed
and delivered in connection with this Agreement shall survive the Closing for a
period of eighteen (18) months, except as specifically provided to the contrary

     Section 14.02  Indemnification by Sellers. Sellers, jointly and severally,
agree to indemnify and to hold Buyer and its shareholders, officers, directors,
employees, representatives and agents harmless from and against and in respect
of any losses, damages, costs, expenses (including costs of investigations and

"Losses") suffered or incurred by them arising from or related to:

          (a)  Any misrepresentation on the part of Sellers or either of them
set forth in this Agreement, the Deed, the Bill of Sale, the Assumption
Agreement or in any closing certificate

                                       27

<PAGE>


delivered by Sellers to Buyer pursuant to Article XI hereof (except to the
extent that Buyer is covered by insurance with respect thereto); and

          (b)  All reasonable costs and expenses (including reasonable
attorneys' fees) incurred by Buyer in connection with any action, suit,
proceeding, demand, assessment or judgment incident to any of the matters Buyer
is indemnified against by Sellers in this Agreement.

     Section 14.03  Indemnification by Buyer. Buyer agrees to indemnify and to
hold Sellers and their shareholders, officers, directors, employees,
representatives and agents harmless from and against and in respect of any
Losses suffered or incurred by them arising from or related to:

          (a)  All liabilities, including all claims and demands relating to or
arising from Buyer's ownership, operation or control of the Purchased Assets
after the Closing and Buyer's assumption of the Assumed Liabilities and
operation by Buyer of the Business;

          (b)  Any misrepresentation on the part of Buyer under this Agreement,
the Assumption Agreement or in any closing certificate delivered by Buyer to
Sellers pursuant to Article XII hereof (except to the extent that Sellers are
covered by insurance with respect thereto); and

          (c)  All reasonable costs and expenses (including reasonable
attorneys' fees) incurred by Sellers in connection with any action, suit,
proceeding, demand, assessment or judgment incident to any of the matters
Sellers are indemnified against by Buyer in this Agreement.

     Section 14.04  Escrow. To partially secure the indemnification provisions
of Section 14.02, at Closing, Sellers shall execute Escrow Agreement No. 2, but
in no event shall Sellers be required by reason of this Section 14.04 to
increase Escrow Amount No. 2 required by Section 5.06(a).

     Section 14.05  Notice of Claims; Defense of Third Party. A party claiming
indemnification under this Article XIV (the "Asserting Party") must promptly
notify (in writing and in reasonable detail) the party from which
indemnification is sought (the "Defending Party") of the nature and basis of
such claim for indemnification not later than eighteen (18) months after the
Closing Date (the "Termination Date") or such party shall lose its rights to
such indemnification. In the event that any legal proceedings, shall be
instituted or that any Third Party Claim (defined below) or demand shall be
asserted by any Person in respect of which indemnity may be sought under Section
14.02 or 14.03, the Asserting Party shall reasonably and promptly cause written
notice of the assertion of any Third Party Claim of which it has knowledge which
is subject to such indemnity to be forwarded to the Defending Party, provided,
however, that the failure to notify the Defending Party shall not affect the
Defending Party's obligation hereunder except to the extent of actual prejudice.
If such claim relates to a claim, suit, litigation or other action by a third
party against the Asserting Party or any fixed or contingent liability to a
third party (a "Third Party Claim"), the Defending Party may elect to assume and
control the defense of the Third Party Claim at its own expense with counsel
selected by the Defending Party from and after such time as the Defending Party
unconditionally agrees in writing to accept, as against the Asserting Party, all
liabilities on account of such Third Party Claim. Assumption of such liability,
as against the Asserting Party, shall not be deemed an

                                       28

<PAGE>


admission of liability as against any such third party. Notwithstanding the
foregoing, the Defending Party may not assume or control the defense if the
named parties to the Third Party Claim (including any impleaded parties) include
both the Defending Party and the Asserting Party and representation of both
parties by the same counsel (in such counsel's reasonable determination) would
be inappropriate due to actual or potential differing interests between them, in
which case the Asserting Party shall have the right to defend the Third Party
Claim and to employ counsel reasonably approved by the Defending Party, and to
the extent the matter is determined to be subject to indemnification hereunder,
the Defending Party shall reimburse the Asserting Party for the reasonable costs
of its counsel. If the Defending Party assumes liability for the Third Party
Claim as against the Asserting Party and assumes the defense and control of the
Third Party Claim pursuant to this Section 14.05, the Defending Party shall not
be liable for any fees and expenses of counsel for the Asserting Party incurred
thereafter in connection with the Third Party Claim (except in the case of
actual or potential differing interests, as provided in the preceding sentence),
but shall not agree to any settlement of such Third Party Claim which does not
include an unconditioned release of the Asserting Party by the third party
claimant on account thereof, provided that such requirement shall be deemed
waived to the extent that the Asserting Party does not undertake to provide and
promptly execute and, concurrently with the delivery of any such release,
deliver a corresponding release of the third party claimant with respect to such
Third Party Claim. If the Defending Party does not assume liability for and the
defense of the Third Party claim pursuant to this Section 14.05, the Asserting
Party shall have the right (i) to control the defense thereof, and (ii) if the
Asserting Party shall have notified the Defending Party of the Asserting Party's
intention to negotiate a settlement of the Third Party Claim (at the Defending
Party's expense to the extent the matter is determined to be subject to
indemnification hereunder), which notice shall include the material terms of any
proposed settlement in reasonable detail, to settle the Third Party Claim (at
the Defending Party's expense to the extent the matter is determined to be
subject to indemnification hereunder) on terms not materially inconsistent with
those set forth in such notice, unless the Defending Party shall have notified
the Asserting Party in writing of the Defending Party's election to assume
liability for and the defense of the Third Party Claim pursuant to this Section
14.05 within ten (10) Business Days after receipt of such notice, and the
Defending Party promptly thereafter shall have taken appropriate action to
implement such defense. The Asserting Party shall not be entitled to settle any
such Third Party Claim pursuant to the preceding sentence unless such settlement
includes an unconditional release of the Defending Party by the third party
claimant on account thereof, provided that such requirements shall be deemed
waived to the extent that the Defending Party does not undertake to provide and
promptly execute and, concurrently with delivery of any such release, deliver a
corresponding release of the third party claimant with respect to such Third
Party Claim. The Asserting Party and the Defending Party shall use all
reasonable efforts to cooperate fully with respect to the defense and settlement
of any Third Party Claim covered by this Article XIV.

     Section 14.06  Limitations. The obligations of Sellers to indemnify Buyer
pursuant to this Article XIV shall be subject to the following limitations:

          (a)  No indemnification shall be required to be made unless the
aggregate amount of Buyer's Losses exceeds Two Hundred Fifty Thousand Dollars
($250,000) minus the Non-Excess Damage (the "Deductible"), and then
indemnification shall only be required to be made to the extent of Buyer's
Losses that exceeds the Deductible.

                                       29

<PAGE>


          (b)  No indemnification shall be required to be made for any Buyer's
Losses that exceed $5,000,000.

          (c)  No indemnification shall be required to be made under Section
14.02 of this Agreement to the extent Buyer (or any of Buyer's officers,
directors, or legal or financial advisors) had actual knowledge of any fact,
information, circumstance or event that would constitute or support a claim that
(i) Sellers misrepresented to Buyer any fact or information covered by any
representation contained in this Agreement, or any of the agreements, documents
or instruments contemplated by this Agreement, or (ii) Sellers breached or, with
the passage of time, would reasonably be expected to breach, any of their
warranties or failed or, with the passage of time, would reasonably be expected
to fail to fulfill any of their agreements or covenants contained in this
Agreement, or in any of the agreements, documents, or instruments contemplated
by this Agreement.

          (d)  The indemnification obligation of a Defending Party shall be
reduced so as to give effect to any net reduction in federal, state, local or
foreign income or franchise tax liability realized at any time by the Asserting
Party in connection with the satisfaction by the Defending Party of a claim with
respect to which indemnification is sought hereunder. The indemnification
obligation of a Defending Party shall also be reduced to the extent of any
available insurance proceeds received by the indemnified party, provided,
however that such reduction shall not be effective until the Asserting Party has
realized the benefit of any such tax reduction or has received any such
insurance proceeds. The Defending Party shall pay its indemnification
obligations as and when required by this Article XIV and the Asserting Party
shall refund to the Defending Party any such amounts determined to be in excess
of the Defending Party's obligations due to reductions pursuant to this Section

     Section 20.10  Waiver. The failure of any party to insist upon strict

     Section 20.13  Governing Law. Any and all issues arising out of or with
respect to Sections 7.01 and 7.02 of this Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to any choice of law or conflicting provision or rule (whether of the
State of New York or any other jurisdiction) that would cause the laws of any
jurisdiction other than the State of New York to be applied. With respect to all
other matters, this Agreement shall be governed by and construed in accordance
with the laws of the Commonwealth of Pennsylvania, without giving effect to any
choice of law or conflicting provision or rule (whether of the Commonwealth of
Pennsylvania or any other jurisdiction) that would cause the laws of any
jurisdiction other than the Commonwealth of Pennsylvania to be applied. In
furtherance of the foregoing, the internal law of the Commonwealth of
Pennsylvania will control the interpretation and construction of this Agreement,
even if under such jurisdiction's choice of law or conflict of law analysis, the
substantive law of some other jurisdiction would ordinarily apply. Any legal
action or proceeding with respect to this Agreement should be brought
exclusively in the courts of the Commonwealth of Pennsylvania or of the United
States that are located in York County, Pennsylvania and, by execution and
delivery of this Agreement, each party hereto hereby irrevocably

                                       41

of counterparts and any party hereto may execute any such counterpart, each of
which when executed and delivered shall be deemed to be an original and all of
which counterparts taken together shall constitute but one and the same
instrument. The execution of this Agreement by any party hereto will not become
effective until counterparts hereof have been executed by all the parties
hereto. It shall not be necessary in making proof of this Agreement or any
counterpart hereof to produce or account for any of the other counterparts.
