validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and has the corporate power to own
and operate its properties, to carry on its business as now
conducted and to enter into and to perform its obligations under
this Agreement, the Registration Rights Agreement between the
Company and Purchaser dated of even date herewith (the

and delivered by Purchaser in connection herewith or therewith
(collectively, the "Operative Documents").  The Company is
qualified to do business and is in good standing in each state or
other jurisdiction in which such qualification is necessary under
applicable provisions of law; except where the failure to so
qualify would not have a material adverse effect on the financial
condition or result of operations of the Company.  The states or
other jurisdictions in which the Company is so qualified are set
forth on Schedule 2.1(a) hereto.  A certified charter of the
Company and a good standing certificate for each state in which
it is qualified to do business are attached to Schedule 2.1(a).

          (b)  Schedule 2.1(b) sets forth a complete list of each
corporation, partnership, joint venture, limited liability
company or other business organization in which the Company owns,
directly or indirectly, any capital stock or other equity
interest (the "Subsidiary" or, collectively, the "Subsidiaries"),
or with respect to which the Company or any Subsidiary, alone or
in combination with others, is in a control position, which list
shows the jurisdiction of incorporation or other organization and
the percentage of stock or other equity interest of each
Subsidiary owned by the Company.  Each Subsidiary is duly
organized, validly existing and in good standing under the laws
of the jurisdiction of incorporation or other organization as
indicated on Schedule 2.1(b), each has all requisite power and
authority and holds all material licenses, permits and other
required authorizations from government authorities necessary to
own its properties and assets and to conduct its business as it
is now being conducted, and is qualified to do business as a
foreign corporation (or business organization) and is in good
standing in every jurisdiction in which such qualification is
necessary under applicable provisions of law; except where the
failure to so qualify would not have a material adverse effect on
the financial condition or results of operations of the company. 
All of the outstanding shares of capital stock, or other equity
interest, of each Subsidiary owned, directly or indirectly, by
the Company have been validly issued, are fully paid and
nonassessable, and are owned by the Company free and clear of all
liens, charges, security interests or encumbrances.  A certified
charter for each Subsidiary and good standing certificates for
each of the states in which each Subsidiary is qualified to do
business are attached to Schedule 2.1(b).

          (c)  Schedule 2.1(c) sets forth a complete list of
"affiliates," of the Company as that term is defined in Rule 405
of Regulation C adopted under the Securities Act of 1933, as
amended (the "Securities Act"), with a brief statement describing
the basis of each affiliation.

     Section 2.2.  Capitalization.
     
          (a)  The authorized capital stock of the Company
consists of (i) 10,000,000 shares of common stock, par value $.10

rights and preferences to be fixed by the Board of Directors in

which, as of the Closing, 25,000 shall have been designated as
"Series A Convertible Preferred Stock," bearing the rights,
preferences and limitations set forth in the Statement With
Respect to Shares and none of which are outstanding.  All shares
of Common Stock outstanding have been validly issued and are
fully paid and nonassessable.  There are no statutory or
contractual pre-emptive rights, rights of first refusal,
antidilution rights or any similar rights held by any party with
respect to the issuance of the Preferred Stock.  The offer, sale
and issuance of the Preferred Stock do not require registration
under the Securities Act or any applicable state securities laws.

          (b)  The Company has not granted, or agreed to grant or
issue, any options, warrants or rights to purchase or acquire
from the Company any shares of capital stock of the Company, and
there are no securities outstanding which are convertible into or
exchangeable for shares of Common Stock, or contracts,
commitments, agreements, understandings, arrangements or
restrictions as to which the Company is a party, or by which it
is bound, relating to any shares of capital stock or other
securities of the Company, whether or not outstanding except for
(i) the conversion privileges of the Preferred Stock to be issued
pursuant to this Agreement, with respect to which 416,666.67
shares of Common Stock have been reserved for issuance upon

a summary of such options, warrants and other rights to acquire
capital stock of the Company.

          (c)  The Preferred Stock that is being purchased by the
Purchaser, when issued, sold, and delivered in accordance with
the terms of this Agreement for the consideration expressed
herein, will be duly and validly issued, fully paid, and
nonassessable, and will be free of restrictions on transfer other
than restrictions on transfer under this Agreement and under
applicable state and federal securities laws.  The Common Stock
issuable upon conversion of the Preferred Stock being purchased
under this Agreement has been duly and validly reserved for
issuance and, upon issuance in accordance with the terms of the
Statement With Respect to Shares and this Agreement, will be duly
and validly issued, fully paid, and nonassessable and will be
free of restrictions on transfer other than restrictions on
transfer under this Agreement and under applicable state and
federal securities laws.

     Section 2.3.  Authorization.

     The Company has full legal right, power and authority to
enter into and perform its obligations under this Agreement and
any of the other Operative Documents, without the consent or
approval of any other person, firm, governmental agency or other
legal entity.  The execution and delivery of this Agreement and
the Operative Documents, the issuance of the Preferred Stock
hereunder, the execution and delivery of each other document in
connection herewith or therewith to which the Company is a party,
and the performance by the Company of its obligations hereunder
and/or thereunder are within the corporate powers of the Company
and have been duly authorized by all necessary corporate action
properly taken, have received all necessary governmental
approvals, if any were required.  The consummation of the
transactions contemplated by this Agreement and the fulfillment
of the terms hereof do not and will not contravene or conflict
with the Articles of Incorporation or Bylaws of the Company or
any material agreement to which the Company or any of its
Subsidiaries is now a party or by which any of them or their
properties is bound, or constitute a default thereunder; or
results in the creation or imposition of any lien, charge,
security interest, or encumbrance of any nature upon any of the
property or assets of the Company or any of its Subsidiaries
pursuant to the terms of any such agreement or instrument; or
violates any provision of law or any applicable judgment,
ordinance, regulation or order of any court or governmental
agency.  The officer(s) executing this Agreement, the Operative
Documents and any other document executed and delivered by
Purchaser in connection herewith or therewith, is duly authorized
to act on behalf of the Company.

     Section 2.4.  Validity and Binding Effect.

     Each of the Operative Documents is the legal, valid and
binding obligation of the Company, enforceable against the
Company in accordance with its terms.

     Section 2.5.  Contracts and Other Commitments.

     Except as disclosed on Schedule 2.5, the Company and its
Subsidiaries do not have and are not bound by any contract,

interests upon which the Company or any Subsidiary is obligated
or by which the Company is bound other than (i) contracts for the
purchase of supplies and services that were entered into in the
ordinary course of business and that do not involve more than
$50,000, and do not extend for more than one (1) year beyond the
date hereof, (ii) sales contracts entered into in the ordinary
course of business, and (iii) contracts terminable at will by the
Company on more than thirty (30) days' notice without cost or
liability to the Company and that do not involve any employment
or consulting arrangement and are not material to the conduct of
the Company's business.  Consummation of the transactions hereby
contemplated and the performance of the obligations of the
Company under and by virtue of the Operative Documents will not
result in any breach of, or constitute a default under, any
material mortgage, security deed or agreement, deed of trust,
lease, bank loan or credit agreement, or any corporate articles,
certificate or bylaws, agreement or certificate of limited
partnership, partnership agreement, limited liability company
agreement, license, franchise or any other material instrument or

or its properties may be bound or, to the knowledge or the
Company, affected or to which the Company has not obtained an
effective waiver.

     Section 2.6.  Litigation.

arbitration, claim, proceeding or investigation pending or
threatened in writing in which the Company or any Subsidiary is a
party or to which any of its respective properties or assets is

Subsidiary, would individually or in the aggregate have a
material adverse effect on the financial position, results of
operations or business of the Company and its Subsidiaries, taken
as a whole.

     Section 2.7.  Financial Statements.

     The consolidated financial statements of the Company and its
Subsidiaries for the fiscal years ended February 25, 1994,
February 24, 1995, and February 23, 1996, and the unaudited
consolidated financial statements as of the nine (9) months ended
November 29, 1996, which the Company previously has heretofore
delivered to Purchaser, fairly present the financial condition of
the Company and its Subsidiaries as at the effective dates of and
for the periods referred to in such financial statements and have
been prepared in accordance with generally accepted accounting
principles ("GAAP") consistently followed throughout the periods
involved.  The consolidated balance sheets and the related notes
fairly present the financial condition of the Company and its
consolidated Subsidiaries as of the respective dates thereof, and
the consolidated statements of income, cash flows and changes in
stockholders' equity and the related notes fairly present the
results of operations of the Company and its consolidated
Subsidiaries for the respective periods indicated.  There has
been no material adverse change in the condition, financial or
otherwise, of the Company and its Subsidiaries taken as a whole
since November 29, 1996.

     The Company's Common Stock is listed on the American Stock
Exchange and has been duly registered with the Securities and
Exchange Commission ("SEC") under the Securities Exchange Act of
1934, as amended (the "Exchange Act")].  Since February 26, 1993,
the Company has filed all reports, registrations, proxy or
information statements and all other documents, together with any
amendments required to be made thereto, required to be filed with
the SEC under the Securities Act and the Exchange Act
(collectively, the "SEC Reports").  Since February 26, 1995, the
Company has timely filed all SEC Reports.  The financial
statements contained in the SEC Reports fairly presented the
financial position of the Company as of the dates mentioned and
the results of operations, changes in stockholders' equity and
changes in financial position or cash flows for the periods then
ended in conformity with GAAP applied on a consistent basis
throughout the periods involved.  The Company previously has
furnished to Purchaser true copies of all the SEC Reports,
together with all exhibits thereto that Purchaser has requested. 
As of their respective dates, the SEC Reports complied (or will
comply, as the case may be) in all material respects with all
rules and regulations promulgated by the SEC and did not (or will
not, as the case may be) contain any untrue statement of a
material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were
made, not misleading.

     Section 2.9.  Absence of Changes.

     Since November 29, 1996, (i) neither the Company nor any of
its Subsidiaries have incurred any liabilities or obligations,
direct or contingent, or entered into any transactions, not in
the ordinary course business, that are material to the Company,
(ii) neither the Company nor any of its Subsidiaries have
purchased any of its outstanding capital stock or declared, paid
or otherwise made any dividend or distribution of any kind on its
capital stock, (iii) there has not been any change in the capital
stock, long-term debt or short-term debt of the Company, and
(iv) there has not been any material adverse change, or any
development involving a prospective material adverse change, in
or affecting the condition (financial or otherwise), results of
operations, business or prospects of the Company or any
Subsidiary, taken as a whole.

     Section 2.
     Except as set forth on Schedule 2.10 and except where a
default or event of default does not and would not constitute a
Material Adverse Event, no default or event of default by the
Company or any Subsidiary exists under this Agreement or any of
the other Operative Documents, or under any other instrument or
agreement to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or its respective properties
may be bound or, to the knowledge of the Company, affected, and
no event has occurred and is continuing that with notice or the
passage of time or both would constitute a default or event of
default thereunder.

     Section 2.11.  Compliance With Law.

     To the Company's knowledge, the Company is in compliance
with all laws, regulations, decrees and orders applicable to it
(including but not limited to laws, regulations, decrees and
orders relating to environmental, occupational and health
standards and controls, antitrust, monopoly, restraint of trade
or unfair competition) to the extent that noncompliance, in the
aggregate, cannot reasonably be expected to cause a Material
Adverse Event.

     Section 2.12.  Taxes.

     Except as set forth on Schedule 2.12, the Company and its
Subsidiaries have filed or caused to be filed all federal, state
and local income, excise and franchise tax returns required to be
filed (except for returns that have been appropriately extended),
and has paid, or provided for the payment of, all taxes shown to
be due and payable on said returns and all other taxes,
impositions, assessments, fees or other charges imposed on it by
any governmental authority, agency or instrumentality, prior to
any delinquency with respect thereto (other than taxes,
impositions, assessments, fees and charges currently being
contested in good faith by appropriate proceedings, for which
appropriate amounts have been reserved), and the Company does not
know of any proposed assessment for additional taxes or any basis
therefor.  No tax liens have been filed against the Company or
any of its properties.  The Company's federal income tax
liability has been finally determined by the Internal Revenue
Service and satisfied for all taxable years up to and including
the taxable year ended February 24, 1995 or closed by applicable
statutes of limitation.

     Section 2.13.  Certain Transactions.

indebtedness incurred in the ordinary course of business and

title to all of real and material personal property owned by it,

encumbrances, equities claims and restrictions of every kind and

except for such liens, security interests, pledges, encumbrances,
equities claims and restrictions which are not in the aggregate
