ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

          On March 10, 1995, the Registrant acquired from Carefree Learning
          Centers, Inc. ("Carefree"), a Pennsylvania corporation and a
          subsidiary of Medical Service Association of Pennsylvania, doing
          business as Pennsylvania Blue Shield ("Pennsylvania Blue Shield"),
          Carefree's child day-care business and operations, and substantially
          all of its other assets, other than real estate, used in the operation
          of Carefree's business.  Additionally, the Registrant acquired from
          another subsidiary of Pennsylvania Blue Shield (i) a leasehold estate
          at which one of the child day-care centers acquired from Carefree is
          currently in the permitted pre-development stage (the "Leasehold
          Estate"), which Leasehold Estate the Registrant contemporaneously
          assigned to one of its wholly-owned subsidiaries, and (ii) a leasehold
          interest in the land and buildings at which one of the child day-care
          centers acquired from Carefree is currently under construction.

          The child day-care business purchased from Carefree, which generated
          revenues of approximately $4,446,000 in 1994, consists of eight child
          day-care centers currently in operation, and three child day-care
          centers currently under construction or in the pre-development stage,
          all of which are located in Pennsylvania.  The Registrant intends to
          continue to operate the acquired business under the Carefree Learning
          Centers name.

          The purchase price for the business and assets acquired from Carefree
          consisted of (i) $500,000 in cash, (ii) a subordinated promissory note
          of the Registrant in the principal amount of approximately $1,585,000,
          and (iii) the assumption of certain other liabilities of Carefree in
          the amount of approximately $360,000.

          Concurrently with the acquisition of Carefree's business and the
          Leasehold Estate, the Registrant and one of its wholly-owned
          subsidiaries entered into an Agreement of Sale (the "Agreement of
          Sale") with a subsidiary of Pennsylvania Blue Shield, pursuant to
          which the Registrant's subsidiary will acquire (i) the land and
          buildings on which four of the child day-care centers currently in
          operation and acquired from Carefree are located, and (ii) the land
          and buildings at which one of the child day-care centers acquired from
          Carefree is currently under construction

                                      -2-
<PAGE>
 
          (collectively, the "Real Estate").  At the closing under the Agreement
          of Sale, the purchase price to be paid for the Real Estate will
          consist of (i) approximately $1,500,000 in cash, (ii) subordinated
          promissory notes of the Registrant in the aggregate principal amount
          of approximately $600,000, and (iii) the assumption by the Registrant
          of certain other liabilities of the Pennsylvania Blue Shield
          subsidiary in the amount of approximately $2,700,000.  The Registrant
          anticipates closing its acquisition of the Real Estate within 60 days
          of the date of the Agreement of Sale.  Following this closing, the
          Registrant anticipates selling all of the Real Estate to an investor
          group and then leasing the Real Estate from the investor group under
          long term leases.  While discussions are underway between the
          Registrant and various investor groups for this purpose, there can be
          no assurances that the Registrant will enter into any such sale and
          leaseback arrangement.

          The cash portion of the purchase price paid by the Registrant for the
          acquisition of Carefree's business was financed by drawing on the
          Registrant's existing line of credit with CoreStates Bank.

          The Registrant proposes financing the purchase price for the
          acquisition of the Real Estate through a term loan in an amount up to
          $3,705,000 (the "Loan") with First Valley Bank ("First Valley") and
          through borrowings of $1,500,000 under the Registrant's existing line
          of credit with CoreStates Bank.  The Loan will be secured by mortgage
          liens on the Real Estate, by assignments of the Registrant's
          subsidiary's rights to any future leases and licenses affecting any
          parcel of such Real Estate and by security interests in fixtures at
          any parcel of the Real Estate.

          The Registrant is not aware of any material relationship between
          Pennsylvania Blue Shield, Carefree, or any of the other subsidiaries
          of Pennsylvania Blue Shield involved in the Registrant's acquisition
          of the Assets or the Real Estate, on the one hand, and the Registrant,
          any of the Registrant's affiliates, any of the Registrant's directors
          or officers, or any associates of the Registrant's directors or
          officers, on the other hand.

                       REPORT OF INDEPENDENT ACCOUNTANTS


Board of Directors
Carefree Learning Centers, Inc.
Exton, Pennsylvania

We have audited the accompanying balance sheets of Carefree Learning Centers, 
Inc. as of December 31, 1994 and 1993, and the related statements of operations,
changes in stockholder's equity (deficit) and cash flows for the years then 
ended.  These financial statements are the responsibility of the Company's 
management.  Our responsibility is to express an opinion on these financial 
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation. 
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Carefree Learning Centers, Inc.
as of December 31, 1994 and 1993, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting 
principles.

                                    _______


1.  Summary of Significant Accounting Policies:
    ------------------------------------------ 

         Description of the Business:
         --------------------------- 

    Carefree Learning Centers, Inc. (the Company) is a wholly-owned subsidiary
    of Keystone Ventures, Inc.  (KVI, a wholly-owned subsidiary of Pennsylvania
    Blue Shield).  The Company was incorporated in 1989 for the purpose of
    operating child day care centers.  All of the Company's business is
    conducted in Pennsylvania.

           Furniture and Equipment:
           ------------------------

    Furniture, equipment and leasehold improvements are carried at cost.
    Maintenance and repairs are expensed as incurred.  Depreciation is computed
    under the straight-line method over the estimated useful lives.  When assets
    are retired or otherwise disposed of, the cost and related accumulated
    depreciation are removed from the accounts and any resulting gain or loss is
    included in operations.

         Other Assets:
         -------------

    Other assets consist principally of prototype and design costs for the
    center model used by the Company.  These costs are amortized by the
    straight-line method over a five-year period.

         Income Taxes:
         -------------

    The Company files a consolidated federal income tax return   with
    Pennsylvania Blue Shield (PBS) and its other subsidiaries.  Under the tax-
    sharing agreement with PBS, federal income taxes are calculated and
    allocated to the Company as if it were a stand alone entity.  The Company is
    also subject to state income taxes.

                                   Continued

1.  Summary of Significant Accounting Policies, continued:
    ------------------------------------------            

         Income Taxes, continued:
         ------------            

    The Company accounts for income taxes based on the provisions of Statement
    of Financial Accounting Standards No. 109, "Accounting for Income Taxes,"
    which requires recognition of deferred tax liabilities and assets for the
    expected future tax consequences of events that have been recognized in the
    financial statements or tax returns.  Under this method, deferred tax
    liabilities and assets are determined based on the difference between the
    financial statement and tax basis of assets and liabilities using enacted
    tax rates in effect for the year in which the differences are expected to be

    settled or realized.


2.  Cash Management:
    --------------- 

    The Company has a cash management agreement with PBS.  Under the terms of
    the agreement, PBS funds the Company checking account daily as required and
    any excess cash in the Company checking account is invested by PBS.
    Invested balances earn interest at a rate equal to the prime rate minus 2%
    computed monthly based on the average daily balance, as defined.  There were
    no invested balances during 1994 and 1993.


3.  Related Party Transactions:
    -------------------------- 

    The Company shares corporate office space with Keystone Real  Estate
    Development Company, Inc. (KREDCO), a wholly-owned subsidiary of KVI.  The
    Company directly bills KREDCO a pro rata share of the building operating
    expenses on a monthly basis.  KREDCO was charged $9,953 and $9,823 for
    operating expenses during the years ended December 31, 1994 and 1993,
    respectively.

    Certain Company employees spend a portion of their time on the operations of
    KREDCO.  The Company bills a portion of expenses for salaries and benefits
    to KREDCO based on employee time allocation.  The Company charged $144,594
    and

    $132,979 to KREDCO for salaries and benefits during the years ended December
    31, 1994 and 1993, respectively.

    The Company is charged for management fees by KVI.  For the years ended
    December 31, 1994 and 1993, management fee expense was $86,056 and $95,936,
    respectively.

                                   Continued

3.  Related Party Transactions, continued:
    --------------------------            

    The Company incurs a monthly charge from PBS for services performed.  The
    services include investment administration and insurance monitoring.  For
    the years ended December 31, 1994 and 1993, the total service charges were
    $13,525 and $10,820, respectively.

    The Company has an available line of credit with PBS of $2.6 million, of
    which $1,507,111 and $1,717,403 were outstanding at December 31, 1994 and
    1993, respectively.  The credit line expires in September 1997 and renews
    annually thereafter at the discretion of PBS.  The Company is required to
    use excess cash from its checking accounts to repay the credit line.  The
    outstanding balance is classified as a noncurrent liability and bears
    interest at the prime rate plus 1%.  Interest charged on the line of credit
    was $128,931 and $133,546 in 1994 and 1993, respectively.  The prime rate of
    interest was 8.5% and 6% at December 31, 1994 and 1993, respectively.

</TABLE>

    The gross deferred tax assets of $127,112 ($76,557 in 1993) consist
    primarily of future deductible amounts for deferred rent, deferred, tuition
    and depreciation.  Management has concluded, as a result of the Company's
    history of operations, that a full valuation allowance be applied to the
    deferred tax assets.

    The Company's effective tax rates of 17.8% in 1994 and 18.3% in 1993 differ
    from the statutory rate of 34% primarily due to the valuation allowance
    being provided for future deductible amounts.

delivery by each Company of this Agreement on the date hereof, the execution and
delivery by each Company on the Closing Date of the Companies' Transaction
Documents to which it is a party, and the performance by each Company of its
respective obligations hereunder and thereunder have been duly and validly

          5.8. Permits.       Except as set forth on Schedule 5.8
               -------                               ------------
attached hereto and made a part hereof, Schedule 1.1.8 is a true, correct and

<PAGE>
 
arbitrator, and there is no such dispute, claim, action, suit, proceeding,
arbitration, inquiry or investigation pending or, to the best knowledge of any
Company, threatened before any court, governmental unit or arbitrator:  (i) that
questions any of the transactions contemplated by this Agreement or the validity

Company to enter into or perform its respective obligations under this Agreement
or any such Companies' Transaction Documents; (ii) with respect to any of the
Purchased Assets or the Business; or (iii) that allege any incident or

effect on the earnings, business operations or condition (financial or
otherwise) of the Business, Seller or its assets.

          5.11.    Financial Information.
                   --------------------- 

               5.11.1.  Schedule 5.11.1 attached hereto and made a part
                        ---------------                                
hereof contains true, correct and complete copies of Seller's audited balance
sheets as at December 31, 1992, 1993 and 1994, and the related audited
statements of operations, cash-flow and stockholders' equity at and for the
years then ended (Seller's audited balance sheet as at December 31, 1994 is
referred to hereinafter as "Seller's Balance Sheet," and all such financial
statements are hereinafter referred to collectively as the "Annual Statements").
The Annual Statements present fairly in all material respects the financial
position of Seller, the Business and its operations at such dates and the
results of its operations and its cash flow for the periods then ended, in
conformity with GAAP, consistently applied.  For the month ended January 31,
1995, Seller had revenues of not less than $350,000, and a net loss of not more
than $100,000, as determined in conformity with GAAP.

               5.11.2.  Neither Seller nor the Business has any liabilities
or obligations which are required by GAAP to be reflected on Seller's Balance
Sheet as at December 31, 1994 ("Seller's Balance Sheet Date") that are not so
reflected thereon, except for such current liabilities (within the meaning of
GAAP) as have been incurred by Seller in the ordinary course of business,
consistent in nature and amount with past practice since Seller's Balance Sheet
Date.  Without limiting the foregoing, Seller's Balance Sheet at Seller's
Balance Sheet Date contains adequate reserves or other appropriate provisions
for accrued income and other taxes, depreciation and the costs of all

                                     -13-
<PAGE>
 
pension, retirement, incentive, bonus, profit-sharing, vacation, holiday or
other plans or policies (if any) for the benefit of Seller's and/or the
Business's employees.

          5.12.    Tax Matters.  Seller has timely and properly filed all
                   -----------                                           
Federal, state, county and local returns and reports relating to Taxes (as
hereinafter defined) and all such returns and reports were true, correct and
complete in all material respects when filed.  All Federal, state, county and
local income, profits, franchise, sales, use, payroll, premium, occupancy,
property, severance, excise, withholding, customs, unemployment, transfer and
other taxes, including interest, additions to tax and penalties (collectively,
"Taxes") due or properly shown to be due on any return referred to in the
preceding sentence by Seller with respect to taxable periods ending on or prior
to, and the portion of any interim period up to, the date hereof have been fully
and timely paid or, in the case of Taxes not yet due, fully provided for on
Seller's Balance Sheet or, in the case of Taxes accruing after the Balance Sheet
Date, on the books of account of Seller.  There are no levies, liens, or other
encumbrances relating to Taxes existing, pending or, to the knowledge of
Companies, threatened with respect to any asset of Seller.  The tax returns of
Seller have never been audited by the Internal Revenue Service or any other
taxing authority.  No issues have been raised with any representative or
employee of Seller and are currently pending by the Internal Revenue Service or
any other taxing authority in connection with such tax return and no waivers of
statutes of limitations have been given or requested with respect to any such
returns and reports or with respect to any Taxes.  The books and records of
Seller are sufficient to prove in all material respects the correctness of all
tax returns for open tax years and to determine and to prove the adjusted tax
basis for Federal income tax purposes of each asset of Seller.

          5.13.    Absence of Certain Changes.  Since Seller's Balance
                   --------------------------                         
Sheet Date, there has not been any material adverse change in the condition
(financial or otherwise), assets, liabilities, properties or operations of the
Business, and, except as disclosed in Schedule 5.13 attached hereto and made a
                                      -------------                           
part hereof, Seller has not:

               5.13.1.  sold, assigned, leased, transferred, mortgaged,
pledged or imposed any lien or other encumbrance on any of its assets or
properties, except in the ordinary course of business and consistent in nature
and amount with past practice;

               5.13.2.  suffered any material damage, destruction or loss,
whether or not covered by insurance, or suffered any repeated, recurring or

of its business or operations which has had or might have a material adverse
effect on the operations, assets or properties of the Business;

               5.13.3.  increased the salaries or other compensation of, or
made any advance (excluding advances for ordinary and necessary business
expenses) or loan to, any of its shareholders, directors, officers or employees,
or made any increase in, or any additions to, other benefits to which any of its
shareholders, directors, officers or employees may be entitled other than salary
increases to non-management level employees made in the ordinary course of
business;

               5.13.4.  changed any of the accounting principles followed
by it or the methods of applying such principles;

               5.13.5.  entered into any material transaction, or any

registration fees or otherwise collected such fees other than in the ordinary
course of business and consistent in nature and amount with past practice; or

or make, any dividends, distributions or other payments in respect of its stock;

or accelerated the collection of its accounts receivable, made any extraordinary
efforts to collect any of its accounts receivable or otherwise collected its
accounts receivable other than in the ordinary course of business and consistent
in nature with past practice.

          5.14.    Title to Property.  Except as described on Schedule 5.14
                   -----------------                          -------------

Assets, free and clear of any restriction, mortgage, deed of trust, pledge,
lien, security interest or other charge, claim or encumbrance other than the
Permitted Encumbrances.

                   ----------------------------------   --------------

Shield or Seller, as the case may be, to be named as an additional insured on
all policies of insurance maintained by Buyer on the applicable leased
properties.  Blue Shield or Seller, as the case may be, shall not be named loss
payee on any property/casualty insurance, so that Blue Shield or Seller, as the
case may be, shall not control insurance proceeds.

          11.4.    Covenant Not To Compete.

type which is now or hereafter located within a 10-mile radius of any child care
center which constitutes part of the Purchased Assets operated by Buyer at the
Closing Date, or any other child care center owned by Buyer in the Commonwealth
of Pennsylvania, the locations of which will be disclosed to Companies upon
their written request to Buyer.

               11.4.2.  From and after the Closing Date, no Covered Party shall
disclose directly or indirectly to any person or entity outside of the employ of
Buyer, without the express authorization of Buyer in each such instance, any
customer or client lists, pricing strategies, customer, client and employee
files and records, any proprietary data or trade secrets of Buyer or the
Business, or any financial or other information about Buyer or the Business not
in the public domain.

               11.4.3.  For a period of five (5) years from and after the

their association or employment, with Buyer.

               11.4.4.  Notwithstanding the foregoing provisions of this Section

11.4, no Covered Party shall be precluded hereby from purchasing or owning,
----
directly or indirectly, securities of any entity that are publicly traded so
long as the Covered Party does not own beneficially five percent (5%) or more of
any class of securities of such entity. Additionally, notwithstanding the
foregoing, each Covered Party may disclose any information subject to the
provisions of Section 11.4.2 (i) to its employees, counsel, auditors and

entity shall be informed by such Covered Party of the confidential nature of
such proprietary information and shall be directed by such Covered Party not to
disclose to any person or entity or make public such information), (ii) to the
extent required by any applicable laws, rules or regulations, and (iii) in any
action, suit or proceeding between Buyer and such Covered Party.

               11.4.5.  Each Company expressly acknowledges that damages alone
shall be an inadequate remedy for any breach or violation of any of the
provisions of this Section 11.4, and that Buyer, in addition to all other
                   ------------
remedies under this Agreement, shall be entitled as a matter of right to
injunctive relief, including specific performance, with respect to any such
breach or violation, in any court of competent jurisdiction.

warranties of Companies and Buyer hereunder, and the right of Buyer or
Companies, as the case may be, to indemnification for breach thereof, shall not
be affected, limited, eliminated or modified by any investigation of Companies
or Buyer, as the case may be, made by Buyer or Companies or its or their
respective agents or Representatives.

                 --------------- 

               11.6.1.  Companies, jointly and severally, shall indemnify
and hold harmless Buyer, and Buyer shall indemnify and hold harmless Companies
(the party or parties providing such indemnification being hereinafter referred
to individually and collectively as the "Indemnifying Party") against any and
all losses, costs, expenses, claims, damages or liabilities (including the
amount of any settlement approved by such Indemnifying Party and expenses of
enforcing this Agreement), which the party or parties seeking such

reimbursement for actual out-of-pocket expenses incurred as the result of such
request by the Indemnifying Party. If the Indemnifying Party does not elect
either to assume control or otherwise participate in the defense of any third-
party claim, the Indemnifying Party shall be bound by the results obtained by
the Indemnified Party with respect to such claim.

right-of-way, easements, encroachments or violations or exceptions to title or

Seller written notice (a "Survey Defect Notice") of any Survey Defects. If Buyer

after receipt of the Survey for any Site, such Survey Defects with respect to
such Site existing shall be deemed to have been accepted and waived by Buyer.

          4.3. Removal.  Seller shall have fifteen (15) business days

                            ----------                                 
requirement at Closing set forth in Section 16.2.2, and the performance by
                                            ------
Seller of each of the following covenants with respect to a Site therefore
constitutes a condition to Buyer's obligation to purchase each applicable Site.
If title to any Site cannot be conveyed to Buyer at the applicable Closing in
accordance with the requirements of Section 5.2 as to a Site, or if Seller
                                    -----------
breaches its covenants under Section 5.3 or 5.4 of this Agreement as to a Site,
                             -----------    ---

simple title to the Existing Centers and the Chadds Ford Center, all in
accordance with the Title Commitments.

          5.3. Prohibited Acts of Seller re: Condition of Title.  From
               ------------------------------------------------       
the Effective Date until the KREDCO Closing Date (with respect to the Property
other than the Chadds Ford Center) or the Chadds Ford Closing Date (with respect
to the Chadds Ford Center) or earlier termination of this Agreement, Seller will




                                     -18-

not, without first obtaining Buyer's prior written consent in each instance:

               5.3.1.       mortgage or encumber any Site;

restrictions, rights-of-way or leases with respect to any Site;

               5.3.3.       enter into any recorded or unrecorded contracts or
leases (other than this Agreement and the Keystone Lease Amendment) with respect
to any Site;

               5.3.4.       seek any zoning changes or other governmental
approvals with respect to any Site; or

would materially adversely affect the condition of title to the Site from and
after the Effective Date through the completion of the KREDCO Closing (with

(with respect to the Chadds Ford Center).

          5.4. Seller's Covenant re: Existing Mortgage(s) and Taxes.
               ---------------------------------------------------- 
Except as disclosed on Schedule 10.2 attached hereto and made a part hereof,
                       -------------                                        
during the term of this Agreement, Seller will keep any existing mortgage(s)
against each Site current and not in default and will pay in a timely fashion
all taxes and other public charges against each Site so as to avoid a forfeiture
of Buyer's rights under this Agreement as to such Site.

     SECTION 6.       SELLER'S NON-CONDITIONAL COVENANTS

          6.1. Effect of Breach of Non-Conditional Covenants.   Seller's
               ---------------------------------------------            
covenants (including negative covenants) set forth in this Section 6 are NOT
                                                           ----------     ---
subject to the certification requirement at Closing set forth in Section 16.2.2,
                                                                 -------------- 
and the failure by Seller to perform any of the following covenants (or Seller's
breach of any negative covenants) therefore does NOT constitute a condition to,
                                                 ---                           
or in any way void or impair, Buyer's obligation to purchase the Property;
                                                                          
PROVIDED, HOWEVER, that Buyer shall otherwise retain all of its rights and
--------  -------

Buyer's indemnification rights pursuant to Section 22.5.

Landlord) of each of the leases to which the Keystone Lease Amendment relates
(each, a "Keystone Lease"), to the effect that Buyer, as tenant under each such
Keystone Lease, upon paying the rental and performing the covenants to be
performed by the tenant under any Keystone Lease, shall and may peaceably and
quietly have, hold, and occupy the applicable Center for the term of the
applicable Keystone Lease, even in the event that any of Seller's lenders take

result of the Keystone Lease Amendment.

Date (or the earlier termination of this Agreement), Seller shall not take, or
omit to take, any action which would cause any representation and warranty made

other than the Chadds Ford Center) or as of the date of the Chadds Ford Closing
(with respect to representations and warranties made as to the Chadds Ford
Center only).

          6.5. Chadds Ford Covenants.  Between the date hereof and the
               ---------------------

rights under the Chadds Ford Construction Contract, to the extent permitted by
law and under the terms of Chadds Ford Construction Contract.

representation or warranty were made as of the date of the KREDCO Closing Date
or as of the date of the Chadds Ford Closing, as applicable.

          7.3. Evaluation Material.

     SECTION 8.       BUYER'S OPTIONS WITH RESPECT TO INCURABLE SURVEY DEFECTS,

               ---------------------------------                 
pursuant to Section 4.4, fails to have a Survey Defect for any Site removed or
            -----------                                                       
insured over or adequately provided for in accordance with Section 4.3, or (b)
                                                           -----------

deemed waived by Buyer; or

               8.1.2.       terminating this Agreement with respect to such

          SECTION 9.  REPRESENTATION AND WARRANTY OF SELLER AS OF THE
EFFECTIVE DATE AND AS OF EACH CLOSING DATE

          Seller represents and warrants to Buyer, as of the Effective Date and
as of each applicable Closing Date, that Seller has the full legal right, power
and authority to execute, deliver and perform its obligations under this
Agreement, the Escrow Agreement and the other agreements and documents (to which
Seller is a party) required to be delivered into the Escrow by Seller or to
Buyer at either Closing pursuant hereto or thereto (collectively, the "Seller's
Transaction Documents"). The execution and delivery by Seller of this Agreement
on the date hereof, the execution and delivery by Seller on either Closing Date
of the Seller's Transaction Documents to which it is a party, and the
performance by Seller of its respective obligations hereunder and thereunder
have been duly and validly authorized by all necessary action of Seller.  This
Agreement and the Escrow Agreement have been duly executed and delivered by
Seller.  This Agreement and the Escrow Agreement are, and when executed and
delivered at either Closing each of Seller's Transaction Documents will be, the
legal, valid and binding obligations of Seller, enforceable against Seller in
accordance with their respective terms, except as such may be limited by
bankruptcy, insolvency, moratorium, reorganization or other similar laws
relating to or affecting the enforcement of creditors' rights generally, and
except that the availability of specific performance, injunctive relief or other
equitable remedies is subject to the discretion of the court before which any
such proceeding therefor may be brought.

          SECTION 10.  REPRESENTATIONS AND WARRANTIES OF SELLER AS OF THE
EFFECTIVE DATE

          Seller represents and warrants to Buyer, as of the Effective Date (but
not as of any applicable Closing Date), as follows:

          10.1.        Organization; Authority.  Seller has been duly
                       -----------------------                       
incorporated and is a corporation validly subsisting and in good standing under
the laws of the Commonwealth of Pennsylvania and has full corporate power and
authority and to own the Property and to carry on its business as now conducted.
Seller is not qualified to do business as a foreign corporation in any
jurisdiction, and neither the nature of the Property nor the conduct of its
business requires that it be so qualified.  All of the shares of capital stock
of Seller are owned, both beneficially and of record, by Keystone Ventures.  All
of the issued and outstanding shares of capital stock of Seller have been duly
authorized and are validly issued and outstanding.

default under:

or

               10.2.3.      any lease or contract being assigned to Buyer
pursuant hereto, or any other material agreement, indenture, instrument or
contract to which Seller is now a party or by which Seller is bound.

          10.3.        Consents and Approvals.  No consent, waiver, approval,
                       ----------------------                                
license or authorization of, or filing, registration or qualification with, or
notice to, any governmental authority or any other person or entity is required

obtained).

          10.4.        Brokers.  No person or entity acting on behalf of Seller
                       -------

          10.5.        Intentionally omitted.

          10.6.        Compliance with Laws.  Except as reflected in the Phase

operation of the Property and has obtained (or required Carefree to obtain) all
licenses, approvals and permits required for the conduct thereof (other than
permits required for the completion and operation of the Chadds Ford Center).

Federal, state or municipal entity or notice of an intention by any such
government entity to revoke any certificate of occupancy or other certificate,
license, approval or permit issued by it in connection with the use of the
Property that in each case has not been cured or otherwise resolved to the
satisfaction of such government entity, except where such failure or such action
could not or would not have a material adverse effect on the Property.

          10.7.        Permits.  Schedule 10.7 is a true, correct and
                       -------   -------------                       
complete list of all permits, franchises, licenses, patents, copyrights,
trademarks and other governmental authorizations which are necessary for Seller
to own the Property and for the conduct Seller's business as now conducted (the
"Permits").  Seller owns, possesses or has the legal right to use the Permits,
free of all liens, pledges, claims, or other encumbrances of any nature
whatsoever.  All Permits are transferable without the consent of any other
person or entity unless otherwise indicated in Schedule 10.7.  Seller knows of
                                               -------------                  
no default under, nor has Seller received any notice of any claim or default or
any other claim or proceeding relating to, any such Permit.

          10.8.        Encumbrances Created by this Agreement.  The execution

Documents does not, and the consummation by Seller of the transactions
contemplated hereby or thereby will not, create any liens or other encumbrances
on any assets of Seller in favor of third parties other than Buyer.

          10.9.        Judgments and Litigation.  Except for those matters
                       ------------------------                           
disclosed in the Phase I Environmental Report for the Audubon Land and Audubon
Leasehold Estate and otherwise disclosed on Schedule 10.9 attached hereto and

not have a material adverse effect on either the transactions contemplated by
this Agreement or the Property, there is no outstanding order, writ, injunction,
fine, citation, penalty, decree or unsatisfied judgment against Seller, its
assets or the Property, of any court, governmental authority or arbitrator, and
there is no such dispute, claim, action, suit, proceeding, arbitration, inquiry
investigation pending or, to the best knowledge of Seller, threatened before any
court, governmental authority or arbitrator:

               10.9.1.      that questions any of the transactions contemplated
by this Agreement or the validity of this Agreement




                                     -26-
<PAGE>
 
or any of the Seller's Transaction Documents or any of the transactions
contemplated hereby or thereby or which, if adversely determined, could
reasonably be expected to have an adverse effect upon the ability of Seller to
enter into or perform its respective obligations under this Agreement or any of
Seller's Transaction Documents or any such transactions; or

               10.9.2.      with respect to any of the Property.

                                      -------------                            
state of facts or occurrence of any event that might reasonably form the basis
of any claim against Seller, or its business or assets (including, but not
limited to, the Property), which might have a materially adverse effect on its
business or assets (including, but not limited to, the Property).

          10.10.       Financial Information.
                       --------------------- 

                  10.10.1.  Schedule 10.10.1 attached hereto and made a part
                            ----------------                                
hereof contains true, correct and complete copies of Seller's audited balance
sheets as at December 31, 1992, 1993 and 1994, and the related audited
statements of operations, cash flow and stockholders' equity at and for the
years then ended (the Balance Sheet and all such financial statements are
hereinafter referred to collectively as the "Annual Statements").  The Annual
Statements present fairly in all material respects the financial position of
Seller, the business and its operations at such dates and the results of its
operations and its cash flow for the periods then ended, in conformity with
GAAP, consistently applied.

                  10.10.2.  Seller has no liabilities or obligations which are
required by GAAP to be reflected on the Balance Sheet as at December 31, 1994
defined in Section 1.1.2 that are not so reflected thereon, except for such
           -------------                                                   
current liabilities (within the meaning of GAAP) as have been incurred by Seller
in the ordinary course of business, consistent in nature and amount with past
practice since Balance Sheet Date.  Without limiting the foregoing, the Balance
Sheet at the Balance Sheet Date contains adequate reserves or other appropriate
provisions for accrued income and other taxes, depreciation and the costs of all
pension, retirement, incentive, bonus, profit-sharing, vacation, holiday or
other plans or policies (if any) for the benefit of Seller's employees.

          10.11.       Tax Matters.  Seller has timely and properly filed all
                       -----------                                           
Federal, state, county and local returns and reports relating to Taxes (as
hereinafter defined) and all such returns and reports were true, correct and
complete in all material respects when filed.  All Federal, state, county and
local income, profits, franchise, sales, use, payroll, premium,




                                     -27-
<PAGE>
 
occupancy, property, severance, excise, withholding, customs, unemployment,
transfer and other taxes, including interest, additions to tax and penalties
(collectively, "Taxes") due or properly shown to be due on any return referred
to in the preceding sentence by Seller with respect to taxable periods ending on
or prior to, and the portion of any interim period up to, the date hereof have
been fully and timely paid or, in the case of Taxes not yet due, fully provided
for on Seller's Balance Sheet or, in the case of Taxes accruing after the
Balance Sheet Date, on the books of account of Seller.  There are no levies,
liens, or other encumbrances relating to Taxes existing, pending or, to the
knowledge of Seller, threatened with respect to any asset of Seller.  The tax
returns of Seller have never been audited by the Internal Revenue Service or any
other taxing authority.  No issues have been raised with any representative or
employee of Seller and are currently pending by the Internal Revenue Service or
any other taxing authority in connection with such tax return and no waivers of
statutes of limitations have been given or requested with respect to any such
returns and reports or with respect to any Taxes.  The books and records of
Seller are sufficient to prove in all material respects the correctness of all
tax returns for open tax years and to determine and to prove the adjusted tax
basis for Federal income tax purposes of each asset of Seller.

          10.12.       Absence of Certain Changes.  Except for Seller's
                       --------------------------

Ford Note and the creation of its Construction-in-Process account, since
Seller's Balance Sheet Date, there has not been any material adverse change in
the condition (financial or otherwise), assets, liabilities, properties or
operations of the Business, and, except as disclosed in Schedule 10.1.2 attached
                                                        ---------------         
hereto and made a part hereof, Seller has not:

               10.12.1.     sold, assigned, leased, transferred, mortgaged,
pledged or imposed any lien or other encumbrance on any of its assets or
properties other than liens relating to the Chadds Ford Debt, except in the
ordinary course of business and consistent in nature and amount with past
practice;

               10.12.2.     suffered any material damage, destruction or loss,
whether or not covered by insurance, or suffered any repeated, recurring or
prolonged shortage, cessation or interruption of delivery of supplies or utility

or might have a material adverse effect on the operations, assets or properties
of its business;

made any advance (excluding advances for ordinary and necessary business
expenses) or loan to, any of its shareholders, directors, officers or employees,
or made any increase in, or any additions to, other benefits to which any of its
shareholders, directors, officers or employees may be entitled other than salary
increases to non-management level employees made in the ordinary course of
business;

               10.12.4.     changed any of the accounting principles followed
by it or the methods of applying such principles;

Ford Center and in the ordinary course of business and consistent in nature and
amount with past practice; or

without limitation, any amounts of principal or interest payable pursuant to
loans) or otherwise dealt with its accounts payables in a manner not consistent
with past practice; or accelerated the collection of its accounts receivable,
made any extraordinary efforts to collect any of its accounts receivable or
otherwise collected its accounts receivable other than in the ordinary course of
business and consistent in nature with past practice.

          10.13.       Property.
                       -------- 

               10.13.1.     Seller:  (a) is the sole owner of the Property

   ------------ 

          SECTION 12.  REPRESENTATION AND WARRANTY OF BUYER AND ASSIGNEE AS OF

to which Buyer or Assignee is a party or by which it is bound.

Assignee in connection with the execution, delivery and performance by Buyer or
Assignee of this Agreement or any of Buyer's Transaction Documents or for the
consummation by Buyer or Assignee of the transactions contemplated hereby or
thereby.

          13.4.        Litigation.  There is no pending, or to the knowledge of

Buyer or Assignee, threatened suit, action or litigation, or administrative,
arbitration or other proceeding or governmental inquiry or investigation which:
(i) if adversely determined, could reasonably be expected to have a material
adverse effect upon the ability of Buyer or Assignee to perform its obligations
hereunder or under any of Buyer's Transaction Documents; or (ii) questions the
validity of this Agreement or the transactions contemplated hereby.

          13.5.        Brokers.  No person or entity acting on behalf of Buyer,
                       -------

foregoing is, or will be, entitled to any broker's, advisor's or finder's fee or
any other commission or similar fee, directly or indirectly, from any of such
parties in connection with any of the transactions contemplated by this
Agreement or the Asset Purchase Agreement.

          13.6.        Financial Condition.  Buyer's most recent Annual Report
                       -------------------                                    
on Form 10-K filed with the Securities and Exchange Commission for 1993 and
Buyer's Quarterly Reports on Form 10-Q filed with the Securities and Exchange
Commission for the first three quarters of 1994 contain true, correct and
complete copies of Buyer's audited balance sheets as of December 31, 1992 and
1993, and the related audited statements of income, cash flow and stockholders'
equity for the two years then ended, and Buyer's unaudited balance sheets as at
March 31, June 30 and September 30, 1994 (September 30, 1994 being hereinafter
referred to as "Buyer's Balance Sheet Date") and the related unaudited
statements of income, cash flow and stockholders' equity for the quarters then
ended (collectively, the "Financial Statements").  The Financial Statements
present fairly in all material respects the consolidated financial position of
Buyer and its subsidiaries at such dates and the results of their operations and
cash flows for the periods then ended, in conformity with GAAP.  For the fiscal
year ended December 31, 1994, Buyer had consolidated revenues of not less than
$34,300,000, and consolidated net income before preferred dividends of not less
than $2,300,000. Since Buyer's Balance Sheet Date, there has occurred no
material adverse change in the financial condition of Buyer and its subsidiaries
nor any occurrence, circumstance or event which impairs or could reasonably be
expected to impair the ability of Buyer to duly and punctually pay or perform
its obligations under the Working Capital Note or the Chadds Ford Note. Assignee
is a newly formed entity with no current operations.

obligated to carry casualty insurance on the Existing Centers, naming Seller and
its mortgagees as co-loss payees.  In the event that an insured casualty or a

                         ----------------------
this Note to the contrary, the indebtedness evidenced by this Note shall be
subordinate and junior, to the extent and in the manner set forth below, to all
"Senior Indebtedness" of Maker.

               3.1.1     SENIOR INDEBTEDNESS. (a) As used herein, the term
                         -------------------
"Senior Indebtedness" of Maker means (i) all "Existing Senior Indebtedness" of
Maker, as defined in Section 3.1.2 below, (ii) all "Permitted Additional Senior
                     -------------
Indebtedness" of Maker, as defined in Section 3.1.3, and (iii) all interest,
                                      -------------
prepayment premiums, collection charges and expenses, and post-petition interest
accruing after an Insolvency Event as defined in Section 3.2.1 below, payable by

<PAGE>
 
          (b)   Notwithstanding anything herein to the contrary, Senior
Indebtedness does not include (i) accounts payable to trade creditors of Maker
however treated or classified on Maker's balance sheet, (ii) rental obligations
under operating leases, or (iii) any indebtedness which by its express terms is
subordinated or pari passu with the right of payment set forth in this Note.

          3.1.2  EXISTING SENIOR INDEBTEDNESS.  As used herein, the term
                 ----------------------------                           
"Existing Senior Indebtedness" means (i) all indebtedness of Maker to CoreStates
Bank, N.A. and Foothill Capital Corp. under that certain Amended and Restated
Revolving Credit and Term Loan Agreement, dated May 2, 1990, as amended,
restated, substituted, or modified from time to time (the "CoreStates Credit
Facility"), up to a maximum principal amount equal to $12,952,878, which amount
equals 110% of the sum of (i) the principal amount outstanding under the
CoreStates Credit Facility on the date hereof, plus (ii) the maximum additional
principal amount which Maker has the right to borrow under the CoreStates Credit
Facility on the date hereof.

          3.1.3  PERMITTED ADDITIONAL SENIOR INDEBTEDNESS.
                 ---------------------------------------- 

          (a)  Additional indebtedness for borrowed money to a financial
institution in excess of $250,000 in original principal amount and all liability
for rental obligations under any lease which, in accordance with generally
accepted accounting principles, are shown as capitalized obligations on Maker's
balance sheet provided any such liability exceeds $250,000 incurred by Maker
from time to time after the date of this Note, shall constitute "Permitted
Additional Senior Indebtedness" hereunder, if and to the extent, on the date on
which such additional debt is incurred, Maker's Debt-To-Equity Ratio, as
hereinafter defined, does not exceed 4.5 to 1.  If the aforesaid additional debt
so incurred qualifies as Permitted Additional Senior Indebtedness on the date it
is incurred, it shall not thereafter lose that status by reason of Maker's Debt-
To-Equity Ratio on any subsequent date exceeding 4.5 to 1.

          (b)  For purposes hereof, the Maker's Debt-To-Equity Ratio shall be
calculated on any date as the ratio of (i) Maker's total consolidated
liabilities reflected on the liabilities side of its consolidated balance sheet
as of such date, other than accounts payable and accrued liabilities, all as
computed in accordance with generally accepted accounting principles,
consistently applied, and (ii) the Company's stockholder's equity (which
includes all redeemable preferred stock) shown on its balance sheet on such
date, in each case as computed in accordance with generally accepted accounting
principles, consistently applied.

                                      -3-
<PAGE>
 
          (c)  Maker shall deliver written notice to Payee, either prior to or
contemporaneously with the occurrence of Permitted Additional Senior
Indebtedness stating the amount of the Permitted Additional Senior Indebtedness
to be incurred (and considered as Senior Indebtedness) and the name of the
financial institution or other person providing such accommodation and
confirming that immediately after such obligation is incurred, Maker's Debt-To-
Equity Ratio does not exceed 4.5 to 1.

          3.2  SUBORDINATION OF PAYMENTS.  The indebtedness evidenced by
               -------------------------                                
this Note shall be subordinated and junior in right of payment to all Senior
Indebtedness of Maker in the following manner:

               3.2.1     INSOLVENCY, ETC. In the event of any assignment by
                         ---------------
Maker for the benefit of its creditors, any bankruptcy, receivership,
liquidation, reorganization or other similar proceeding, whether instituted by
or against Maker or Maker's business or assets, or any dissolution, liquidation
or other winding-up of the affairs of Maker or of Maker's business (each an
"Insolvency Event"), and in all such cases, then the holders of the Senior
Indebtedness shall be entitled to receive payment in full of all Senior
Indebtedness before Payee is entitled to receive any further payment on account
of principal of or interest on this Note; and to that end the holders of the
Senior Indebtedness shall be entitled to receive, to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid after giving
effect to any concurrent payment or distribution (or provision therefor) to the
holders of the Senior Indebtedness, for application in payment thereof, any
payment or distribution of any kind or character, whether in cash or property or
securities, which may be payable or deliverable in any such proceedings in
respect of this Note.

               3.2.2     DEFAULT ON SENIOR INDEBTEDNESS AND PREPAYMENT AND
                         -------------------------------------------------
ACCELERATION.
------------ 

               (A)  So long as a default exists in the payment of any Senior
Indebtedness whether by acceleration or otherwise, and the giving of written
notice thereof to Payee by the holders of such Senior Indebtedness (a "Payment
Default"), all principal and interest due on such Senior Indebtedness shall
first be paid in full, or such payment duly provided for in a manner
satisfactory to the holders of such Senior Indebtedness, before any further
payment is made on account of the principal of or interest on this Note.

               (B)  Upon the happening of an event of default (other than a
Payment Default) with respect to any Senior Indebtedness (as defined in any
instrument or agreement under which such Senior Indebtedness is outstanding)
which permits the holders of the Senior Indebtedness to accelerate the maturity

thereof, and upon receipt by Payee of written notice thereof and commencement of
a "Payment Blockage Period" (as defined below) by the holders of such Senior
Indebtedness, then, unless and until such event of default shall have been
cured, to the extent that such event of default is curable, or waived or shall
have ceased to exist, no further payment (each such payment, a "Blocked
Payment") shall thereafter be made by Maker with respect to the principal of or
interest on this Note for a period (each a "Payment Blockage Period") commencing
on the date of receipt of such notice and ending 180 days thereafter (unless
such Payment Blockage Period shall be terminated by written notice to Payee from
the holders of Senior Indebtedness).  For purposes of this Section 3.2.2, if one
                                                           -------------        
or more Payment Blockage Periods has been in effect for an aggregate of 60 days
or more (whether or not consecutive) during any six month period, a new Payment
Blockage Period may not be commenced by the holders of Senior Indebtedness,
unless 190 days have lapsed since the expiration or termination of the last of
such previous Payment Blockage Periods.  Additionally, as long as no Payment
Blockage Period is in effect at the end of a Standstill Period and Payee
receives all principal, interest and other sums due to it within five (5) days
of the expiration of such Standstill Period, any Event of Default arising under
                                                                               
Section 4.1 or Section 4.3(ii) which relates to the principal, interest or other
-----------    ---------------                                                  
sums so received shall be deemed to be cured.

               3.2.3     PAYMENTS IMPROPERLY RECEIVED. In the event that any
                         ----------------------------
payment (including any pre-payment) on account of principal of or interest on
this Note shall be received by Payee before all Senior Indebtedness is paid in
full, and at a time when Maker shall be prohibited from making such payment by
Sections 3.2.1 or 3.2.2 hereof, such payment(s) shall be held in trust by Payee
--------------    ----- 
for the benefit of and shall be paid over to the holders of all Senior
Indebtedness ratably according to the aggregate amounts remaining unpaid on
account of the Senior Indebtedness held by each such holder, to the extent
necessary to make payment in full of all Senior Indebtedness. The foregoing
notwithstanding, however, Payee shall not be required to pay any such
distribution of payment to the holders of Senior Indebtedness, if, with respect
to payments or distributions received by Payee during a Payment Default,
Insolvency Event or Payment Blockage Period, Payee has not received written
notice from a holder of the Senior Indebtedness or otherwise does not have
actual knowledge of any applicable Payment Default, Insolvency Event, or Payment
Blockage Period. Notwithstanding anything contained herein to the contrary,
Payee shall be permitted to (i) turn over any payments required to be remitted
to the holders of the Senior Indebtedness to any one or more of the holders of
the Senior Indebtedness and all such holders agree to ratably share such payment
among themselves, and (ii) rely upon the statements of any party reasonably
claiming to be a holder of Senior Indebtedness.

               3.2.4     RIGHTS.
                         ------ 

               (A)  No right of the holders of the Senior Indebtedness to
enforce the subordination provisions contained herein shall be impaired by any
act or failure to act by Maker or Payee. The provisions of this Section 3.2 are
                                                                ----------- 
solely for the purpose of defining the relative rights of the holders of the
Senior Indebtedness, on the one hand, and Payee on the other hand, with respect
to the order in which payments or distributions by or on behalf of Maker shall
be applied to the Senior Indebtedness and the obligations of Maker pursuant to
this Note, and nothing herein shall impair, as between Maker, its creditors
other than the holders of the Senior Indebtedness, and Payee, the obligation of
Maker which is unconditional and absolute, to pay Payee the principal of and
interest on this Note in accordance with its terms, or affect the relative
rights of Payee and creditors of Maker other than the holders of the Senior
Indebtedness. Without limiting the foregoing, Payee has the right to send any
notice described in Section 4.1 hereof at any time Maker fails to make any
                    ----------- 
installments of interest, principal and/or principal and interest or any other
sum due hereunder, including without limitation, during any Payment Blockage
Period, and Standstill Period, any period following any Insolvency Event or any
Payment Default period.

               (B)  Any failure on the part of Maker to make any payment on
account of this Note when due shall, subject to any grace or cure period
applicable under Section 4 or the last sentence of Section 3.2.2 hereof,
                 ---------                         -------------
constitute an Event of Default, even if such failure results from the operation
of this Section 3.2. Payee may accelerate the maturity of, or institute any
        -----------
proceedings to enforce, this Note, or exercise all remedies otherwise permitted
by applicable law or under this Note upon any Event of Default specified in
Section 4 hereof, subject to the rights of the holders of the Senior
---------
Indebtedness under this Section 3.2 to receive cash, property or securities
                        -----------
otherwise payable or deliverable to Payee, and provided that, with respect to
                                               --------
any Event of Default specified herein, Payee shall have first given to the
holders of the Senior Indebtedness one hundred ten (110) days' advance notice
(such 110 day period, a "Standstill Period") of its intention to exercise such
remedies.

               (C)  Upon any payment or distribution of assets of Maker
subsequent to an Insolvency Event, Payee shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which
dissolution, winding-up, liquidation, reorganization, or other similar
proceedings are pending or upon a certificate of the liquidating trustee or
agent or other person or entity making any distribution to Payee for the purpose
of ascertaining the persons or entities entitled to participate in such
distribution, the identity of the holders of the Senior Indebtedness or other
indebtedness of Maker, the

                                      -6-
<PAGE>
 
amount thereof and payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Section 3.2.
                                                         ----------- 

               (D)  Payee hereby agrees that, without any notice to or consent
from Payee, and without any other action in respect of Payee on the part of the
holders of the Senior Indebtedness: (x) the Senior Indebtedness and any
collateral security therefor may (subject to the definition of Senior
Indebtedness) from time to time be renewed, extended, modified, accelerated,
compromised, waived, surrendered or released, (y) documents in connection with
Senior Indebtedness, including collateral security documents and guarantees, may
be amended or modified from time to time, and (z) any collateral security held
by the holder of Senior Indebtedness at any time for the payment of such Senior
Indebtedness may be sold, exchanged, waived, surrendered or released.

               3.2.5  SUBROGATION.  In the event that cash, securities, or other
                      -----------                                               
property otherwise payable or deliverable to Payee shall have been applied
pursuant to this Section 3.2 to the payment of Senior Indebtedness, then,
                 -----------                                             
subject to the payment in full of all Senior Indebtedness, Payee shall (x) be
entitled to receive from the holders of the Senior Indebtedness any payments or
distributions received by the holders of the Senior Indebtedness in excess of
the amount sufficient to pay all Senior Indebtedness in full, and (y) be
subrogated to all rights of the holders of the Senior Indebtedness to receive
any payments or distributions of cash, property, or assets of Maker applicable
to the Senior Indebtedness, until all principal of and interest on this Note
shall be paid in full.  No such payments or distributions received by the
holders of the Senior Indebtedness which, but for the provisions of this Section
                                                                         -------
3.2, would otherwise have been made to Payee shall, as between Maker, its
---                                                                      
creditors other than the holders of the Senior Indebtedness, and Payee, be
deemed to have been made as a payment by Maker to or on account of the Senior
Indebtedness, it being understood that the provisions of this Section 3.2 are
                                                              -----------    
and are intended solely for the purpose of defining the relative rights of
Payee, on the one hand, and the holders of the Senior Indebtedness, on the other
hand.

               3.2.6  WAIVER. No failure to exercise, and no delay in
                      ------
exercising, on the part of the holders of the Senior Indebtedness, any
right, power or privilege hereunder shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies provided in any agreement
relating to any of the Senior Indebtedness, related collateral security
documents and all other agreements, instruments and documents referred to in any
of the foregoing are

                                      -7-
<PAGE>
 
cumulative and shall not be exclusive of any rights or remedies provided by law.

              3.2.7  BINDING EFFECT.  Maker covenants and agrees, and Payee by
                     --------------                                           
acceptance of this Note likewise covenants and agrees that:  (x) this Note is
issued subject to the provisions of this Section 3.2, (y) Payee will be bound by
                                         -----------                            
such provisions, and (z) the holders of the Senior Indebtedness shall be
entitled to enforce the provisions of this Section 3.2 directly against Payee.
                                           -----------                        

          3.3  ENFORCEMENT.  Payee irrevocably authorizes the holders of
               -----------                                              
the Senior Indebtedness (but each such holder of the Senior Indebtedness has no
obligation), upon the occurrence of an Insolvency Event and if Payee shall have
failed to file any proof of claim or similar claim within the earlier of (i)
thirty (30) days after the holders of the Senior Indebtedness have requested
Payee to file such claim, or (ii) fifteen days of any date upon which Payee's
claim would be barred in the applicable proceeding, provided that Payee has
                                                    --------               
received actual notice of the time limitations for filing with respect to such
claim, under the circumstances set forth in Section 3.2.1, to demand, sue for,
                                            -------------                     
collect and receive every such payment or distribution described in that
Section, to file claims and proofs of claims in any statutory or non-statutory
proceeding, to vote the full amount of the indebtedness hereunder in their sole
discretion in connection with any resolution, arrangement, plan of
reorganization, compromise, settlement or extension and to take all such other
action (including, without limitation, the right to participate in any
composition of creditors and the right to vote the amount of the indebtedness
hereunder at creditors' meetings for the election of trustees, acceptances of
plans of reorganization and otherwise), in the name of the holders of the Senior
Indebtedness or in the name of Payee or otherwise, as the holders of the Senior
Indebtedness may deem necessary or advisable for the enforcement of the
subordination provisions of this Note.  Payee agrees to cooperate with the
holders of the Senior Indebtedness as reasonably requested in writing, to the
extent necessary to permit the holders of the Senior Indebtedness to exercise
their rights described in the preceding sentence.  At such time as the holders
of the Senior Indebtedness have exercised their rights under this Section 3.3,
                                                                  ----------- 
they promptly will return any instruments evidencing the indebtedness hereunder
that have been delivered to them by Payee under this Section 3.3, if they have
                                                     -----------              
not been required to deliver such instruments to any other person or entity by
order of court (or other similar authority having jurisdiction over the matter)
or by law.  Notwithstanding the foregoing, payments received by the holders of
the Senior Indebtedness shall not reduce the obligation of Maker to Payee under
this Note, and only payments received by Payee and not subject to any claim by
the holders of the Senior Indebtedness shall reduce the obligation of Maker to
Payee hereunder.

          4.   EVENTS OF DEFAULT.  Each of the following shall constitute an
               -----------------                                            
event of default (each, an "EVENT OF DEFAULT") hereunder:
                            ----------------             

               4.1       PAYMENT FAILURE. If Maker fails to make any payment of
                         --------------- 
any installment of interest, principal and/or principal and interest hereunder
or any other sum due hereunder within five (5) days after Maker's receipt of
notice from Payee of Maker's failure to make such payment on the date such
payment is due.

               4.2       BANKRUPTCY. If any proceeding under the Bankruptcy Code
                         ----------
or any law of the United States or of any state relating to insolvency,
receivership, or debt adjustment is instituted by Maker, or if any such
proceeding is instituted against Maker and is consented to by the respondent or
an order for relief shall be entered in such proceeding or such proceeding shall
remain undismissed for sixty (60) days, or if Maker becomes a debtor under the
Bankruptcy Code or a trustee or receiver is appointed for any substantial part
of its property, or if Maker makes an assignment for the benefit of creditors,
admits in writing its inability to pay debts generally as they become due or
becomes insolvent.

               4.3       OTHER DEFAULTS.  If a default or event of default shall
                         --------------                                         
occur at any time under the terms of any Senior Indebtedness of Maker (i) as a
result of the failure to pay principal or interest on such Senior Indebtedness,
(ii) for which a Payment Blockage Period is instituted, or (iii) in the case of
other defaults which results in the acceleration of the maturity of such Senior
Indebtedness.

               4.4       JUDGMENTS.  If any final unappealable judgment for the
                         ---------                                             
payment of money in excess of $100,000 in the aggregate shall be entered against
Maker by a court having jurisdiction in the premises, which judgment is not paid
or discharged, vacated, bonded or stayed pending appeal within a period of
thirty (30) days from the date of entry.

          5.   REMEDIES.  Upon the occurrence of any Event of Default hereunder,
               --------                                                         
the entire unpaid principal balance of this Note, together with all accrued and
unpaid interest thereon and all other sums owing hereunder shall become
immediately due and payable, without presentation, demand or further action of
any kind, and Payee may forthwith exercise, singly, concurrently, successively
or otherwise, any and all rights and remedies available to Payee hereunder.  The
failure of the holder hereof to accelerate the outstanding principal balance of
this Note upon the occurrence of an Event of Default hereunder shall not
constitute a waiver of such default or of the right to accelerate this Note at
any time thereafter so long as the Event of Default remains uncured. If Payee
retains the services of counsel in

                                      -9-
<PAGE>
 
order to enforce any remedy available to Payee hereunder, all reasonable
attorneys' fees which are actually incurred by Payee shall be payable upon
demand.

          6.   INTEREST LIMITATIONS.  Nothing herein contained nor any
               --------------------                                   
transaction related hereto shall be construed or shall operate either presently
or prospectively to require Maker to pay interest at a rate greater than is now
lawful in such case to contract for, but shall require payment of interest only
to the extent of such lawful rate.  Any interest paid in excess of the lawful
rate shall be refunded to Maker.

          7.   REPORTS.  Maker shall provide Payee with a copy of each report
               -------                                                       
filed with the Securities and Exchange Commission during the term of this Note
within ten (10) days of such filing.

          8.   SEVERABILITY.  In the event that for any reason one or more of
               ------------                                                  
the provisions of this Note or their application to any person or circumstance
shall be held to be invalid, illegal or unenforceable in any respect or to any
extent, such provisions shall, to such extent, be held for naught as though not
herein contained but shall nevertheless remain valid, legal and enforceable in
all such other respects and to such extent as may be permissible.  In addition,
any such invalidity, illegality or unenforceability shall not affect any other
provisions of this Note, but this Note shall be construed as if such invalid,
illegal or unenforceable provisions had never been contained herein.

          9.   SUCCESSORS AND ASSIGNS.  This Note inures to the benefit of
               ----------------------

this Note to the contrary, the indebtedness evidenced by this Note shall be

"Senior Indebtedness" of Maker.

               3.1.1        SENIOR INDEBTEDNESS. (a) As used herein, the term
                            -------------------
"Senior Indebtedness" of Maker means (i) all "Existing Senior Indebtedness" of
Maker, as defined in Section 3.1.2 below, (ii) all "Permitted Additional Senior
                     -------------
Indebtedness" of Maker, as defined in Section 3.1.3, and (iii) all interest,
                                      -------------
prepayment premiums, collection charges and expenses, and post-petition interest
accruing after an Insolvency Event as defined in Section
                                                 ------- 
                                      -2-

-----                                                                          
to Senior Indebtedness.

               (b) Notwithstanding anything herein to the contrary, Senior
Indebtedness does not include (i) accounts payable to trade creditors of Maker
however treated or classified on Maker's balance sheet, (ii) rental obligations
under operating leases, or (iii) any indebtedness which by its express terms is
subordinated or pari passu with the right of payment set forth in this Note.

               3.1.2  EXISTING SENIOR INDEBTEDNESS.  As used herein, the term
                      ----------------------------                           
"Existing Senior Indebtedness" means (i) all indebtedness of Maker to CoreStates
Bank, N.A. and Foothill Capital Corp. under that certain Amended and Restated
Revolving Credit and Term Loan Agreement, dated May 2, 1990, as amended,
restated, substituted, or modified from time to time (the "CoreStates Credit
Facility"), up to a maximum principal amount equal to $12,952,878, which amount
equals 110% of the sum of (i) the principal amount outstanding under the
CoreStates Credit Facility on the date hereof, plus (ii) the maximum additional
principal amount which Maker has the right to borrow under the CoreStates Credit
Facility on the date hereof.

               3.1.3  PERMITTED ADDITIONAL SENIOR INDEBTEDNESS.

               (a) Additional indebtedness for borrowed money to a financial
institution in excess of $250,000 in original principal amount and all liability
for rental obligations under any lease which, in accordance with generally
accepted accounting principles, are shown as capitalized obligations on Maker's
balance sheet provided any such liability exceeds $250,000 incurred by Maker
from time to time after the date of this Note, shall constitute "Permitted
Additional Senior Indebtedness" hereunder, if and to the extent, on the date on
which such additional debt is incurred, Maker's Debt-To-Equity Ratio, as
hereinafter defined, does not exceed 4.5 to 1.  If the aforesaid additional debt
so incurred qualifies as Permitted Additional Senior Indebtedness on the date it
is incurred, it shall not thereafter lose that status by reason of Maker's Debt-
To-Equity Ratio on any subsequent date exceeding 4.5 to 1.

               (b)  For purposes hereof, the Maker's Debt-To-Equity Ratio shall
be calculated on any date as the ratio of (i) Maker's total consolidated
liabilities reflected on the liabilities side of its consolidated balance sheet
as of such date, other than accounts payable and accrued liabilities, all as
computed in accordance with generally accepted accounting principles,
consistently applied, and (ii) the Company's stockholder's equity (which
includes all redeemable preferred stock) shown on its balance sheet on such
date, in each case as computed in accordance with generally accepted accounting
principles, consistently applied.

               (c) Maker shall deliver written notice to Payee, either prior to
or contemporaneously with the occurrence of Permitted Additional Senior
Indebtedness stating the amount of the Permitted Additional Senior Indebtedness
to be incurred (and considered as Senior Indebtedness) and the name of the
financial institution or other person providing such accommodation and
confirming that immediately after such obligation is incurred, Maker's Debt-To-
Equity Ratio does not exceed 4.5 to 1.

               3.2       SUBORDINATION OF PAYMENTS. The indebtedness evidenced
                         -------------------------
by this Note shall be subordinated and junior in right of payment to all Senior
Indebtedness of Maker in the following manner:

                         3.2.1  INSOLVENCY, ETC. In the event of any assignment
                                ----------------                              
by Maker for the benefit of its creditors, any bankruptcy, receivership,
liquidation, reorganization or other similar proceeding, whether instituted by
or against Maker or Maker's business or assets, or any dissolution, liquidation
or other winding-up of the affairs of Maker or of Maker's business (each an
"Insolvency Event"), and in all such cases, then the holders of the Senior
Indebtedness shall be entitled to receive payment in full of all Senior
Indebtedness before Payee is entitled to receive any further payment on account
of principal of or interest on this Note; and to that end the holders of the
Senior Indebtedness shall be entitled to receive, to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid after giving
effect to any concurrent payment or distribution (or provision therefor) to the
holders of the Senior Indebtedness, for application in payment thereof, any
payment or distribution of any kind or character, whether in cash or property or
securities, which may be payable or deliverable in any such proceedings in
respect of this Note.

                         3.2.2  DEFAULT ON SENIOR INDEBTEDNESS AND PREPAYMENT 
                                ---------------------------------------------
AND  ACCELERATION.
----------------- 
                         (A) So long as a default exists in the payment of any
Senior Indebtedness whether by acceleration or otherwise, and the giving of
written notice thereof to Payee by the holders of such Senior Indebtedness (a
"Payment Default"), all principal and interest due on such Senior Indebtedness
shall first be paid in full, or such payment duly provided for in a manner
satisfactory to the holders of such Senior Indebtedness, before any further
payment is made on account of the principal of or interest on this Note.

                         (B) Upon the happening of an event of default (other
than a Payment Default) with respect to any Senior Indebtedness (as defined in
any instrument or agreement under which such Senior Indebtedness is outstanding)
which permits the holders of the Senior Indebtedness to accelerate the maturity

                                      -4-
<PAGE>
 
thereof, and upon receipt by Payee of written notice thereof and commencement of
a "Payment Blockage Period" (as defined below) by the holders of such Senior
Indebtedness, then, unless and until such event of default shall have been
cured, to the extent that such event of default is curable, or waived or shall
have ceased to exist, no further payment (each such payment, a "Blocked
Payment") shall thereafter be made by Maker with respect to the principal of or
interest on this Note for a period (each a "Payment Blockage Period") commencing
on the date of receipt of such notice and ending 180 days thereafter (unless
such Payment Blockage Period shall be terminated by written notice to Payee from
the holders of Senior Indebtedness).  For purposes of this Section 3.2.2, if one
                                                           -------------        
or more Payment Blockage Periods has been in effect for an aggregate of 60 days
or more (whether or not consecutive) during any six month period, a new Payment
Blockage Period may not be commenced by the holders of Senior Indebtedness,
unless 190 days have lapsed since the expiration or termination of the last of
such previous Payment Blockage Periods.  Additionally, as long as no Payment
Blockage Period is in effect at the end of a Standstill Period and Payee
receives all principal, interest and other sums due to it within five (5) days
of the expiration of such Standstill Period, any Event of Default arising under
                                                                               
Section 4.1 or Section 4.3(ii) which relates to the principal, interest or other
-----------    ---------------                                                  
sums so received shall be deemed to be cured.

                         3.2.3 PAYMENTS IMPROPERLY RECEIVED. In the event that
                               ----------------------------
any payment (including any pre-payment) on account of principal of or interest
on this Note shall be received by Payee before all Senior Indebtedness is paid
in full, and at a time when Maker shall be prohibited from making such payment
by Sections 3.2.1 or 3.2.2 hereof, such payment(s) shall be held in trust by
   --------------    -----       
Payee for the benefit of and shall be paid over to the holders of all Senior
Indebtedness ratably according to the aggregate amounts remaining unpaid on
account of the Senior Indebtedness held by each such holder, to the extent
necessary to make payment in full of all Senior Indebtedness. The foregoing
notwithstanding, however, Payee shall not be required to pay any such
distribution of payment to the holders of Senior Indebtedness, if, with respect
to payments or distributions received by Payee during a Payment Default,
Insolvency Event or Payment Blockage Period, Payee has not received written
notice from a holder of the Senior Indebtedness or otherwise does not have
actual knowledge of any applicable Payment Default, Insolvency Event, or Payment
Blockage Period. Notwithstanding anything contained herein to the contrary,
Payee shall be permitted to (i) turn over any payments required to be remitted
to the holders of the Senior Indebtedness to any one or more of the holders of
the Senior Indebtedness and all such holders agree to ratably share such payment
among themselves, and (ii) rely upon the statements of any party reasonably
claiming to be a holder of Senior Indebtedness.

                         3.2.4 RIGHTS.
                               ------ 
                         (A)  No right of the holders of the Senior Indebtedness
to enforce the subordination provisions contained herein shall be impaired by
any act or failure to act by Maker or Payee. The provisions of this Section 3.2
                                                                    -----------

Senior Indebtedness, on the one hand, and Payee on the other hand, with respect
to the order in which payments or distributions by or on behalf of Maker shall
be applied to the Senior Indebtedness and the obligations of Maker pursuant to
this Note, and nothing herein shall impair, as between Maker, its creditors
other than the holders of the Senior Indebtedness, and Payee, the obligation of
Maker which is unconditional and absolute, to pay Payee the principal of and
interest on this Note in accordance with its terms, or affect the relative
rights of Payee and creditors of Maker other than the holders of the Senior
Indebtedness. Without limiting the foregoing, Payee has the right to send any
notice described in Section 4.1 hereof at any time Maker fails to make any
                    -----------
installments of interest, principal and/or principal and interest or any other
sum due hereunder, including without limitation, during any Payment Blockage
Period, and Standstill Period, any period following any Insolvency Event or any
Payment Default period.

                         (B)  Any failure on the part of Maker to make any
payment on account of this Note when due shall, subject to any grace or cure
period applicable under Section 4 or the last sentence of Section 3.2.2 hereof,
                        ---------                         -------------
constitute an Event of Default, even if such failure results from the operation
of this Section 3.2. Payee may accelerate the maturity of, or institute any
        ------------
proceedings to enforce, this Note, or exercise all remedies otherwise permitted
by applicable law or under this Note upon any Event of Default specified in
Section 4 hereof, subject to the rights of the holders of the Senior
--------- 
Indebtedness under this Section 3.2 to receive cash, property or securities
                        -----------
otherwise payable or deliverable to Payee, and provided that, with respect to
                                               --------
any Event of Default specified herein, Payee shall have first given to
the holders of the Senior Indebtedness one hundred ten (110) days' advance
notice (such 110 day period, a "Standstill Period") of its intention to exercise
such remedies.

                         (C)  Upon any payment or distribution of assets of
Maker subsequent to an Insolvency Event, Payee shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction in which
dissolution, winding-up, liquidation, reorganization, or other similar
proceedings are pending or upon a certificate of the liquidating trustee or
agent or other person or entity making any distribution to Payee for the purpose
of ascertaining the persons or entities entitled to participate in such
distribution, the identity of the holders of the Senior Indebtedness or other
indebtedness of Maker, the

                                      -6-
<PAGE>
 
amount thereof and payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Section 3.2.
                                                         ----------- 

                         (D)  Payee hereby agrees that, without any notice to or
consent from Payee, and without any other action in respect of Payee on the part
of the holders of the Senior Indebtedness: (x) the Senior Indebtedness and any
collateral security therefor may (subject to the definition of Senior
Indebtedness) from time to time be renewed, extended, modified, accelerated,
compromised, waived, surrendered or released, (y) documents in connection with
Senior Indebtedness, including collateral security documents and guarantees, may
be amended or modified from time to time, and (z) any collateral security held
by the holder of Senior Indebtedness at any time for the payment of such Senior
Indebtedness may be sold, exchanged, waived, surrendered or released.

                         3.2.5  SUBROGATION. In the event that cash, securities,
                                -----------                              
or other property otherwise payable or deliverable to Payee shall have been
applied pursuant to this Section 3.2 to the payment of Senior Indebtedness,
                         -----------
then, subject to the payment in full of all Senior Indebtedness, Payee shall (x)
be entitled to receive from the holders of the Senior Indebtedness any payments
or distributions received by the holders of the Senior Indebtedness in excess of
the amount sufficient to pay all Senior Indebtedness in full, and (y) be
subrogated to all rights of the holders of the Senior Indebtedness to receive
any payments or distributions of cash, property, or assets of Maker applicable

                                             -----------  
intended solely for the purpose of defining the relative rights of Payee, on the
one hand, and the holders of the Senior Indebtedness, on the other hand.

                         3.2.6  WAIVER. No failure to exercise, and no delay in
                                ------
exercising, on the part of the holders of the Senior Indebtedness, any right,
power or privilege hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. The rights and remedies provided in any agreement relating to any
of the Senior Indebtedness, related collateral security documents and all other
agreements, instruments and documents referred to in any of the foregoing are

                         3.2.7  BINDING EFFECT. Maker covenants and agrees, and
                                --------------
Payee by acceptance of this Note likewise covenants and agrees that: (x) this
Note is issued subject to the provisions of this Section 3.2, (y) Payee will be
                                                 -----------
bound by such provisions, and (z) the holders of the Senior Indebtedness shall
be entitled to enforce the provisions of this Section 3.2 directly against
                                              -----------    
Payee.

                   3.3  ENFORCEMENT. Payee irrevocably authorizes the holders of
                        -----------
the Senior Indebtedness (but each such holder of the Senior Indebtedness has no
obligation), upon the occurrence of an Insolvency Event and if Payee shall have
failed to file any proof of claim or similar claim within the earlier of (i)
thirty (30) days after the holders of the Senior Indebtedness have requested
Payee to file such claim, or (ii) fifteen days of any date upon which Payee's
claim would be barred in the applicable proceeding, provided that Payee has
                                                    --------
received actual notice of the time limitations for filing with respect to such

Section, to file claims and proofs of claims in any statutory or non-statutory
proceeding, to vote the full amount of the indebtedness hereunder in their sole
discretion in connection with any resolution, arrangement, plan of
reorganization, compromise, settlement or extension and to take all such other
action (including, without limitation, the right to participate in any
composition of creditors and the right to vote the amount of the indebtedness
hereunder at creditors' meetings for the election of trustees, acceptances of
plans of reorganization and otherwise), in the name of the holders of the Senior
Indebtedness or in the name of Payee or otherwise, as the holders of the Senior
Indebtedness may deem necessary or advisable for the enforcement of the
subordination provisions of this Note. Payee agrees to cooperate with the
holders of the Senior Indebtedness as reasonably requested in writing, to the
extent necessary to permit the holders of the Senior Indebtedness to exercise
their rights described in the preceding sentence. At such time as the holders of
the Senior Indebtedness have exercised their rights under this Section 3.3, they
                                                               -----------
promptly will return any instruments evidencing the indebtedness hereunder that
have been delivered to them by Payee under this Section 3.3, if they have not
                                                -----------
been required to deliver such instruments to any other person or entity by order
of court (or other similar authority having jurisdiction over the matter) or by
law. Notwithstanding the foregoing, payments received by the holders of the
Senior Indebtedness shall not reduce the obligation of Maker to Payee under this
Note, and only payments received by Payee and not subject to any claim by the
holders of the Senior Indebtedness shall reduce the obligation of Maker to Payee
hereunder.

               4.1       PAYMENT FAILURE. If Maker fails to make any payment of
                         ---------------

notice from Payee of Maker's failure to make such payment on the date such
payment is due.

               4.2       BANKRUPTCY. If any proceeding under the Bankruptcy Code
                         ----------

Bankruptcy Code or a trustee or receiver is appointed for any substantial part

               4.3       OTHER DEFAULTS.  If a default or event of default shall

other defaults which results in the acceleration of the maturity of such Senior
Indebtedness.

                         ---------

unpaid interest thereon and all other sums owing hereunder shall become
immediately due and payable, without presentation, demand or further action of
any kind, and Payee may forthwith exercise, singly, concurrently, successively
or otherwise, any and all rights and remedies available to Payee hereunder.  The
failure of the holder hereof to accelerate the outstanding principal balance of
this Note upon the occurrence of an Event of Default hereunder shall not
constitute a waiver of such default or of the right to accelerate this Note at
any time thereafter so long as the Event of Default remains uncured. If Payee
retains the services of counsel in

                                      -9-

or prospectively to require Maker to pay interest at a rate greater than is now
lawful in such case to contract for, but shall require payment of interest only

-----                                                                          
to Senior Indebtedness.

               (b)  Notwithstanding anything herein to the contrary, Senior
Indebtedness does not include (i) accounts payable to trade creditors of Maker
however treated or classified on Maker's balance sheet, (ii) rental obligations
under operating leases, or (iii) any indebtedness which by its express terms is
subordinated or pari passu with the right of payment set forth in this Note.

               3.1.2  EXISTING SENIOR INDEBTEDNESS.  As used herein, the term
                      ---------------------------- 
"Existing Senior Indebtedness" means (i) all indebtedness of Maker to CoreStates
Bank, N.A. and Foothill Capital Corp. under that certain Amended and Restated
Revolving Credit and Term Loan Agreement, dated May 2, 1990, as amended,
restated, substituted, or modified from time to time (the "CoreStates Credit
Facility"), up to a maximum principal amount equal to $12,952,878, which amount
equals 110% of the sum of (i) the principal amount outstanding under the
CoreStates Credit Facility on the date hereof, plus (ii) the maximum additional
principal amount which Maker has the right to borrow under the CoreStates Credit
Facility on the date hereof.

               3.1.3  PERMITTED ADDITIONAL SENIOR INDEBTEDNESS.
                      ---------------------------------------- 

               (a) Additional indebtedness for borrowed money to a financial
institution in excess of $250,000 in original principal amount and all liability
for rental obligations under any lease which, in accordance with generally
accepted accounting principles, are shown as capitalized obligations on Maker's
balance sheet provided any such liability exceeds $250,000 incurred by Maker
from time to time after the date of this Note, shall constitute "Permitted
Additional Senior Indebtedness" hereunder, if and to the extent, on the date on
which such additional debt is incurred, Maker's Debt-To-Equity Ratio, as
hereinafter defined, does not exceed 4.5 to 1. If the aforesaid additional debt
so incurred qualifies as Permitted Additional Senior Indebtedness on the date it
is incurred, it shall not thereafter lose that status by reason of Maker's Debt-
To-Equity Ratio on any subsequent date exceeding 4.5 to 1.

               (b) For purposes hereof, the Maker's Debt-To-Equity Ratio shall
be calculated on any date as the ratio of (i) Maker's total consolidated
liabilities reflected on the liabilities side of its consolidated balance sheet
as of such date, other than accounts payable and accrued liabilities, all as
computed in accordance with generally accepted accounting principles,
consistently applied, and (ii) the Company's stockholder's equity (which
includes all redeemable preferred stock) shown on its balance sheet on such
date, in each case as computed in accordance with generally accepted accounting
principles, consistently applied.

               (c) Maker shall deliver written notice to Payee, either prior to
or contemporaneously with the occurrence of Permitted Additional Senior
Indebtedness stating the amount of the Permitted Additional Senior Indebtedness
to be incurred (and considered as Senior Indebtedness) and the name of the
financial institution or other person providing such accommodation and
confirming that immediately after such obligation is incurred, Maker's Debt-To-
Equity Ratio does not exceed 4.5 to 1.

               3.2  SUBORDINATION OF PAYMENTS.  The indebtedness evidenced by
                    -------------------------                                
this Note shall be subordinated and junior in right of payment to all Senior
Indebtedness of Maker in the following manner:

                    3.2.1  INSOLVENCY, ETC.  In the event of any assignment by
                           ---------------
Maker for the benefit of its creditors, any bankruptcy, receivership,
liquidation, reorganization or other similar proceeding, whether instituted by
or against Maker or Maker's business or assets, or any dissolution, liquidation
or other winding-up of the affairs of Maker or of Maker's business (each an
"Insolvency Event"), and in all such cases, then the holders of the Senior
Indebtedness shall be entitled to receive payment in full of all Senior
Indebtedness before Payee is entitled to receive any further payment on account
of principal of or interest on this Note; and to that end the holders of the
Senior Indebtedness shall be entitled to receive, to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid after giving
effect to any concurrent payment or distribution (or provision therefor) to the
holders of the Senior Indebtedness, for application in payment thereof, any
payment or distribution of any kind or character, whether in cash or property or
securities, which may be payable or deliverable in any such proceedings in
respect of this Note.

                    3.2.2  DEFAULT ON SENIOR INDEBTEDNESS AND PREPAYMENT AND
                           -------------------------------------------------
ACCELERATION.
------------ 

                    (A)  So long as a default exists in the payment of any
Senior Indebtedness whether by acceleration or otherwise, and the giving of
written notice thereof to Payee by the holders of such Senior Indebtedness (a
"Payment Default"), all principal and interest due on such Senior Indebtedness
shall first be paid in full, or such payment duly provided for in a manner
satisfactory to the holders of such Senior Indebtedness, before any further
payment is made on account of the principal of or interest on this Note.

                    (B)  Upon the happening of an event of default (other than a
Payment Default) with respect to any Senior Indebtedness (as defined in any
instrument or agreement under which such Senior Indebtedness is outstanding)
which permits the holders of the Senior Indebtedness to accelerate the maturity

                                      -4-
<PAGE>
 
thereof, and upon receipt by Payee of written notice thereof and commencement of
a "Payment Blockage Period" (as defined below) by the holders of such Senior
Indebtedness, then, unless and until such event of default shall have been
cured, to the extent that such event of default is curable, or waived or shall
have ceased to exist, no further payment (each such payment, a "Blocked
Payment") shall thereafter be made by Maker with respect to the principal of or
interest on this Note for a period (each a "Payment Blockage Period") commencing
on the date of receipt of such notice and ending 180 days thereafter (unless
such Payment Blockage Period shall be terminated by written notice to Payee from
the holders of Senior Indebtedness).  For purposes of this Section 3.2.2, if one
                                                           -------------        
or more Payment Blockage Periods has been in effect for an aggregate of 60 days
or more (whether or not consecutive) during any six month period, a new Payment
Blockage Period may not be commenced by the holders of Senior Indebtedness,
unless 190 days have lapsed since the expiration or termination of the last of
such previous Payment Blockage Periods.  Additionally, as long as no Payment
Blockage Period is in effect at the end of a Standstill Period and Payee
receives all principal, interest and other sums due to it within five (5) days
of the expiration of such Standstill Period, any Event of Default arising under
                                                                               
Section 4.1 or Section 4.3(ii) which relates to the principal, interest or other
-----------    ---------------                                                  
sums so received shall be deemed to be cured.

                    3.2.3  PAYMENTS IMPROPERLY RECEIVED.  In the event that any
                           ----------------------------
payment (including any pre-payment) on account of principal of or interest on
this Note shall be received by Payee before all Senior Indebtedness is paid in
full, and at a time when Maker shall be prohibited from making such payment by
Sections 3.2.1 or 3.2.2 hereof, such payment(s) shall be held in trust by Payee
for the benefit of and shall be paid over to the holders of all Senior
Indebtedness ratably according to the aggregate amounts remaining unpaid on
account of the Senior Indebtedness held by each such holder, to the extent
necessary to make payment in full of all Senior Indebtedness. The foregoing
notwithstanding, however, Payee shall not be required to pay any such
distribution of payment to the holders of Senior Indebtedness, if, with respect
to payments or distributions received by Payee during a Payment Default,
Insolvency Event or Payment Blockage Period, Payee has not received written
notice from a holder of the Senior Indebtedness or otherwise does not have
actual knowledge of any applicable Payment Default, Insolvency Event, or Payment
Blockage Period. Notwithstanding anything contained herein to the contrary,
Payee shall be permitted to (i) turn over any payments required to be remitted
to the holders of the Senior Indebtedness to any one or more of the holders of
the Senior Indebtedness and all such holders agree to ratably share such payment
among themselves, and (ii) rely upon the statements of any party reasonably
claiming to be a holder of Senior Indebtedness.

subsequent to an Insolvency Event, Payee shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which

power or privilege hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder preclude

FOR IMMEDIATE RELEASE:
--------------------- 

     MEDIA, PENNSYLVANIA, MARCH 13, 1995 . . . NOBEL EDUCATION DYNAMICS, INC.
(NASDAQ:NEDI) announced the completion of the purchase of the Carefree Learning
Centers from a subsidiary of Pennsylvania Blue Shield, according to Jack Clegg,
Nobel's Chairman and CEO.

Carefree is comprised of eight operating learning centers with three in
development.  Carefree is operating at an annual revenue rate of approximately
$5,700,000.

In 1994, Nobel Education Dynamics, Inc. had revenues of $34,371,501 and net
income of $2,339,765 which was 37% over Nobel's 1993 net earnings.  Earnings per
share in 1994 were $0.12 (fully diluted).

The basic terms of the acquisition were $500,000 in cash and the assumption of
Carefree's approximately $1.6 million of subordinated debt to Pennsylvania Blue
Shield in an eight-year note with fixed interest of eight percent (8%) and
skewed principal payments plus a balloon payment at the end of the eight-year
period.

Mr. Clegg stated, "The acquisition of this quality operation in one of Nobel's
core, geographic growth areas is a key component in Nobel's re-growth strategy.
Carefree, in combination with Nobel's schools and centers in Pennsylvania,
provides a preschool cluster which can begin to feed Nobel's grammar school
grades under its Chesterbrook Academy private school entity."
<PAGE>
 
In addition, Nobel entered into an agreement to purchase certain real estate
owned by a subsidiary of Pennsylvania Blue Shield which houses a portion of
Carefree's operations.  Closing of this transaction is anticipated within 60
days.  Mr. Clegg stated that this real estate is being funded through a bridge
loan with First Valley Bank, and Nobel anticipates spinning off the real estate
as a package to real estate investors.  The purpose of acquiring the real estate
was to avoid any delay in the timing of the Carefree acquisition.

Nobel's stated mission is to be the leader in providing safe, quality, private
education and development of children which is affordable to middle income,
working families in the United States.
