          On September 1, 1995, the Registrant acquired all of the outstanding
          shares of common stock of Educo, Inc., a Maryland corporation,
          pursuant to a Stock Purchase Agreement with Educo, Inc. and the then
          existing stockholders of Educo, Inc. (collectively, the "Educo
          Stockholders") dated May 23, 1995, as amended. Educo, Inc. is an
          operator of 10 schools and preschools located in Maryland, Virginia,
          North Carolina and South Carolina. The purchase price for the stock
          consisted of (i) $2,000,000 in cash and (ii) an agreement to issue and
          deliver to the Educo Stockholders an aggregate of 1,250,000 shares of
          the Registrant's Common Stock on January 15, 1996. The cash portion of
          the purchase price was financed with proceeds of the Term Loan from
          First Valley Bank described in Item 5 below.

ITEM 5.   Other Events.
          -------------

          Acquisition of Child Care Centers in Indiana.
          ---------------------------------------------

          On August 25, 1995, the Registrant acquired from Corydon Day Care
          Center, Inc., an Indiana corporation d/b/a "Children Today"
          (Corydon"), nine of its child care centers located in the
          Indianapolis, Indiana area (the "Centers") and substantially all of
          the assets (other than real estate) used by Corydon in the business of
          operating the Centers. The Registrant also acquired a leasehold
          interest in the buildings and the land upon which the Centers are
          located. The purchase price for the business and assets acquired from
          Corydon consisted of (i) $1,050,000 in cash and (ii) a subordinated
          promissory note in the principal amount of $1,125,000 secured by a
          security interest in certain assets located at the Centers. The cash
          portion of the purchase price paid by the Registrant was financed by
          drawing on the Registrant's then existing line of credit with
          CoreStates Bank, N.A. which the Registrant repaid on August 31, 1995
          using proceeds of the Term Loan from First Valley Bank described below
          in this Item 5.

          Refinancing.
          ------------

          On August 30, 1995, the Registrant and certain of its subsidiaries
          (collectively, the "Borrowers") entered into a Loan and Security
          Agreement with First Valley

                                      -2-
<PAGE>
 
          Bank (the "Loan Agreement"). Pursuant to the Loan Agreement, First
          Valley Bank lent the Borrowers a five-year term loan in the original
          principal amount of $7,500,000 (the "Term Loan") and established for
          the Borrowers from August 30, 1995 and until September 1, 1998 a
          revolving line of credit in an amount not to exceed $7,500,000 (the
          "Line"). Such loans are secured by liens in favor of the Bank on the
          Borrowers' properties. The proceeds of the Term Loan were used by the
          Borrowers as follows: (i) $5,500,000 was used by the Registrant to
          repay indebtedness of the Registrant to CoreStates Bank, N.A. and (ii)
          $2,000,000 was used to fund the cash portion of the acquisition by the
          Registrant of Educo, Inc. pursuant to the terms of that certain Stock
          Purchase Agreement by and among the Registrant, Educo, Inc. and the
          Educo Stockholders dated May 23, 1995, as amended. The proceeds
          advanced under the Line shall be used for working capital purposes, to
          fund future acquisitions of educational facilities or companies and
          construction of educational facilities by the Borrowers and for the
          issuance of standby letters of credit; provided however, the sum of
          the outstanding amounts of advances under the revolving line of credit
          for working capital purposes and the face amount under outstanding
          standby letters of credit shall not at any time exceed $1,000,000 in
          the aggregate.

          In addition, on August 30, 1995, the Registrant and certain of its
          subsidiaries (collectively, the "Nobel Companies") entered into an
          Investment Agreement with Allied Capital Corporation and its
          affiliated funds (collectively, "Allied"), pursuant to which, on such
          date, the Registrant sold and issued to Allied (i) Senior Subordinated
          Debentures in the aggregate principal amount of $6,000,000 (the
          "Debentures") for a purchase price of $6,000,000; (ii) 1,063,830
          shares of the Registrant's Series D Convertible Preferred Stock (the
          "Preferred Stock") for a purchase price of $2,000,000; and (iii)
          Warrants to acquire an aggregate of 1,236,171 shares of the
          Registrant's Common Stock, subject to certain adjustments under
          antidilution provisions (the "Warrants") for a purchase price of $100.
          The Nobel Companies have granted liens on certain of their properties
          to Allied securing their obligations to Allied under the foregoing
          documents and instruments. A portion of the proceeds of the sale of
          the foregoing securities was used to refinance bank debt existing on
          August 30, 1995; the remainder will be used for acquisitions and new
          campus opening, for transaction expenses and for general corporate
          purposes.

          The Debentures bear interest at the rate of 14% per annum, and
          principal is repayable commencing October 1, 2000 is equal quarterly
          installments. The Preferred Stock is convertible into an aggregate of
          1,063,830 shares of the Common Stock of the Registrant, subject to
          certain adjustments under antidilution provisions.

the State of Kentucky in each fiscal year since 1977.  The Company 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 the Company 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 the books of account of the Company.  There are no
levies, liens, or other encumbrances relating to Taxes existing, pending or, to
the knowledge of any Seller, threatened with respect to any asset of the
Company.  The tax returns of the Company have never been audited by the Internal
Revenue Service or any other taxing authority.  No issues have been raised by
any representative or employee of the Company 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 the Company 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 the Company.

Material" does not include information which (i) becomes generally available to
the public other than as a result of disclosure by Buyer or any Buyer
Representative in violation of the terms hereof, (ii) was available on a non-
confidential basis prior to its disclosure to Buyer by a Seller or a Seller

from the date on which this Agreement terminates, hire or otherwise interfere
with the Company's employment of any of the key management employees of the
Business listed on Schedule 5.17.1 hereto interviewed by Buyer pursuant to this

               11.4.2    From and after the date hereof, the Company and each
Shareholder shall not disclose directly or indirectly to any person or entity

including, but not limited to, the solicitation of Buyer's customers, clients,
suppliers, associates, employees or independent contractors to cease doing
business, or to discontinue their association or employment, with Buyer.

               11.4.4    Notwithstanding the foregoing provisions of this

------------                                                                
from purchasing or owning, directly or indirectly, securities of any entity that

own beneficially in the aggregate five percent (5%) or more of any class of
securities of such entity, and nothing herein shall preclude the Company or any
Shareholder from operating a Purchased Center as permitted under the Lease for
such Purchased Center in the event Buyer is in default of its obligations under

foregoing, the Company and each of the Shareholders may disclose any information
subject to the provisions of Section 11.4.2 (i) to its employees, counsel,
                             --------------                               
auditors and accountants on a need-to-know basis (it being agreed that any such
person or entity shall be informed by the party of the confidential nature of
such proprietary information and shall be directed by the party not to disclose
to any person or entity or make public such information), (ii) to the extent
required by

                                     -30-

any applicable laws, rules or regulations, and (iii) in any action, suit or
proceeding between Buyer and the Sellers.

               11.4.5    Each Seller 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
                   ------------

breach or violation, in any court of competent jurisdiction.

               11.4.6    The Sellers acknowledge and agree that the covenants

                  ------------                                        
consideration paid hereunder and in order to protect Buyer's investment in the
Business, and the invalidity or unenforceability of this provision, or any other
or part of any provision, of this Agreement shall not affect the other
provisions or parts hereof.  If any provision hereof is determined to be invalid
or unenforceable by a court of competent jurisdiction, the Sellers shall
negotiate in good faith to provide Buyer with protection as nearly equivalent to
that found to be invalid or unenforceable and if any such provision shall be so
determined to be invalid or unenforceable by reason of the duration or
geographical scope, or both, shall be considered to be reduced to a duration or
geographical scope to the extent necessary to cure such invalidity.

delivered by any such party pursuant hereto shall survive the Closing, and each
party hereto shall be entitled to rely upon the representations and warranties
of each other party.  Anything in this Agreement to the contrary
notwithstanding, the representations and warranties of the Sellers hereunder,
and the right of Buyer to indemnification for breach thereof, shall not be
affected, limited, eliminated or modified by any investigation of the Company or
any other Seller made by Buyer or its agents or Representatives.

          11.6.     Indemnification.
                    --------------- 

               11.6.1    The Company and the Shareholders, jointly and
severally, shall indemnify and hold harmless Buyer, and Buyer shall indemnify

providing such indemnification being hereinafter referred to individually and

approved by such Indemnifying Party and expenses of enforcing this Agreement),

party against which an Indemnified Parties is seeking indemnification hereunder,
the Indemnifying Parties shall have the right, at its own expense, to
participate in or assume control of the defense of such claim, and the
Indemnified Parties shall cooperate with the Indemnifying Parties subject to
reim bursement for all expenses incurred as the result of such request by the
Indemnifying Parties.  If the Indemnifying Parties do not within 10 days of
written notice thereof elect either to assume control or otherwise participate
in the defense of any third-party claim, the Indemnifying Parties shall be bound
by the results obtained by the Indemnified Parties with respect to such claim.

case of income or other tax claims and claims relating to environmental matters,
notice may be given within the period of the applicable statute of limitations
provided that neither party takes, nor permits to be taken, any voluntary action

This Section 11.6.3 shall not impose any time limitation on the assertion of
     --------------                                                         
claims for breach of any covenant made by any party or for claims for
indemnification asserted by Buyer against any Seller based upon the assertion
against Buyer of a liability or obligation of a Seller which is

                                     -32-
<PAGE>
 
not an Assumed Liability or for claims for indemnification asserted by a Seller
against Buyer based upon the assertion against such Seller of an Assumed
Liability.

               11.6.4    No Indemnifying Party shall be obligated to indemnify
an Indemnified Party pursuant to Section 11.6.1(i) until the aggregate amount of

entitled under Section 11.6) and the amount of any Extraordinary Expenses
               ------------

stockholder or other affiliate of Maker.

          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, or (ii) rental obligations under
operating leases.

               3.2  SUBORDINATION OF UNSECURED 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.  Subject to Section 3.2.8, 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, 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  MATURITY OF OR DEFAULT ON SENIOR INDEBTEDNESS.
                           --------------------------------------------- 

                    (A)  Subject to Section 3.2.8, upon the maturity of any
                                    -------------
Senior Indebtedness by lapse of time, acceleration, or otherwise, and the giving
of written notice thereof to Payee by the holders of such Senior Indebtedness,
all principal and interest 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)  Subject to Section 3.2.8, upon the happening of an
                                    -------------
event of default with respect to any Senior

                                 Sch. 2.2.2-3
<PAGE>
 
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 written notice of such
default given to Payee by the holders of such Senior Indebtedness, then, unless
and until such event of default shall have been cured or waived or shall have
ceased to exist, no further payment shall thereafter be made by Maker with
respect to the principal of or interest on this Note.

                    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 (but in the case of a
--------------    -----
payment prohibited only by Section 3.2.2(b), only until such event of default or
                           ----------------   
default shall have been cured or waived or shall cease to exist), 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.

                    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 (except as otherwise provided in the
Asset Purchase Agreement), 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.

                    (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 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

                                 Sch. 2.2.2-4

under this Note upon any Event of Default specified in Section 4 hereof, at the
                                                       ---------               
times and in the manner set forth in Section 3.2.8 herein and subject to the
                                     -------------                          
rights of the holders of Senior Indebtedness under such Section.

                    (C)  Upon any payment or distribution of assets of Maker
referred to in this Section 3.2, 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 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) any demand for payment of Senior
Indebtedness made by the holder of such Senior Indebtedness may be rescinded,
and the Senior Indebtedness and any collateral security therefor may 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  ALLOCATION OF PAYMENTS.  No 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

                                  Sch 2.2.2-5
<PAGE>
 
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 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.

                    3.2.8  RIGHTS OF PAYEE UPON PAYMENT DEFAULT.  Upon the
                           ------------------------------------ 
occurrence of any default under Section 4.1 herein, before Payee may exercise
                                -----------
any of its remedies provided herein, it must first give the holders of Senior
Indebtedness two hundred and ten (210) days' advance written notice of its
intention to exercise such remedies. For the period commencing on the date the
holders of Senior Indebtedness receive such notice and ending 210 days
thereafter (the "Remedy Block Period"), each holder of Senior Indebtedness shall
have the sole right to enforce the rights and remedies provided in any
agreement, instrument or other document relating to its Senior Indebtedness and
proceed against its collateral (including the Collateral hereunder), provided
that it (i) commences such action prior to the expiration of the Remedy Block
Period, (ii) liquidates the collateral securing its Senior Indebtedness in a
commercially reasonable manner and (iii) notwithstanding the subordination
provisions contained in Section 3.2 herein and regardless of whether or not the
                        -----------
Senior Indebtedness has been paid in full, remits to Payee, for application
hereunder, out of the proceeds from any liquidation of the Collateral, an amount
equal to the lesser of (i) $250,000, (ii) the amount outstanding under the Note,
or (iii) the net amount derived from the liquidation of such Collateral (the
"Liquidation Amount"). Payee will not take any action, or exercise any rights it
may have, against Maker prior to expiration of the Remedy Block Period, provided
that the foregoing will be subject in any event to the obligation of the holder
of Senior Indebtedness to pay to Payee the Liquidation Amount. Upon expiration
of the Remedy Block Period, regardless of whether or not the holders of Senior
Indebtedness have taken any action, and assuming the default under Section 4.1
                                                                   -----------
has not been cured, then, notwithstanding the subordination provisions contained
in Section 3.2 herein, Payee shall be entitled to file suit against Maker and
   -----------                                                               
obtain a judgment on the Note.  Thereafter, provided the holders of Senior
Indebtedness continue to not take any action against Maker, then Payee can
execute on its judgment against Maker and foreclose on the Collateral or on
other assets of Maker and take any other actions available to

                                 Sch. 2.2.2-6
<PAGE>
 
Payee with respect to the Collateral.  If, however, the holders of Senior
Indebtedness take action after the Remedy Block Period, then the only action
which Payee may take is to file suit and obtain a judgment against Maker (but it
may not execute on such judgment) provided, however, that the foregoing is
                                  --------  -------                       
subject to the obligation of the holders of Senior Indebtedness to pay to Payee
the Liquidation Amount.  Nothing contained herein shall preclude any holder of
Senior Indebtedness from taking any action against Maker before or after the
expiration of the Remedy Block Period provided such holders pay the Liquidation
Amount owed to Payee.

               3.3  ENFORCEMENT.  Payee irrevocably authorizes the holders of
                    -----------                                              
the Senior Indebtedness (but each such holder of the Senior Indebtedness has no
obligation), 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 for
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

                                  Sch 2.2.2-7
<PAGE>
 
principal and interest hereunder or any other sum due hereunder within ten (10)
days after Maker's receipt of notice from Payee of Maker's failure to make such
payment on the date such payment is due; or

               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  CROSS-DEFAULT.  If Maker materially breaches any of its
                    -------------                                          
obligations under or specified in (a) the Security Agreement (as defined in
                                                                           
Section 2 herein), (b) any Lease entered into by Maker in connection with the
---------                                                                    
Asset Purchase Agreement as listed on Exhibit C hereto, or (c) any other Buyer's
Transaction Document as defined in the Asset Purchase Agreement, and such
default continues after the expiration of the applicable notice and grace
period, if any, provided in the applicable agreement.  Nothing herein shall
limit any remedies which Payee may have under any Lease with respect to the
leased premises thereunder in the event of a default by Maker under such Lease.

          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, at the option
of the holder hereof, 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 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

                                 Sch. 2.2.2-8
<PAGE>
 
extent of such lawful rate.  Any interest paid in excess of the lawful rate
shall be refunded to Maker.

          7.   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.

          8.   SUCCESSORS AND ASSIGNS.  This Note inures to the benefit of
               ----------------------                                     
Payee, its successors and assigns, and is binding upon Maker, its successors and
assigns, and the words "Payee" and "Maker" whenever used herein shall be deemed
and construed to include such respective successors and assigns.

               -------                                                         
hereunder shall be in writing and shall be deemed to have been sufficiently
given for all purposes when given in accordance with the terms and conditions of
the Asset Purchase Agreement.

               --------                                                        
are for convenience only and shall not control or affect the meaning or
construction of any of the terms or provisions of this Note.

shareholders of the Company, the Company has this day acquired from Secured
Party, nine (9) child care centers in the Indianapolis, Indiana area (the
"Purchased Centers"), together with substantially all of the assets used in the
business of operating the Purchased Centers (together with the Purchased
Centers, the "Business").  In connection with the Company's acquisition of the
Business, the Company has executed a Subordinated Promissory Note of even date
herewith (the "Note") in the principal amount of $1,125,000.  This Agreement has
been executed and delivered to provide security for the Note under the terms set
forth herein.

          NOW, THEREFORE, the parties agree as follows, intending to be legally
bound.

          SECTION 1.  Grant of Security Interest.  As security for payment when
                      --------------------------                               
due of the principal of and interest on the Note, and for the performance of all
of the obligations of the Company under this Agreement (collectively, the
"Secured Obligations"), the Company hereby grants to Secured Party a security
interest in the property described on Exhibit A attached hereto, and all
proceeds and products of the foregoing, including insurance payable by reason of
loss or damage (collectively, the "Collateral").

          SECTION 2.  Further Assurances.
                      ------------------ 

          (a)  The Company will execute such financing or continuation
statements, or amendments thereto, and such other agreements, instruments or
notices, as may be reasonably necessary to perfect and preserve the security
interests granted or purported to be granted hereby.

          (b)  The Company will furnish to Secured Party from time to time
statements and schedules further identifying and describing the Collateral and
such other reports in connection with the Collateral as Secured Party may
reasonably request, all in reasonable detail.

                                 Sch. 2.2.3-1
<PAGE>
 
          SECTION 3.  Insurance.  The Company shall, at its own expense,
                      ---------                                         
maintain property damage and liability insurance and insurance against loss or
damage to the Collateral, including, without limitation loss by fire, theft and
such other risks of loss as are customarily insured against the types of
Collateral covered hereunder, in such amounts, form and with such insurance as
shall be reasonably satisfactory to the Secured Party.  Each insurance policy
shall name the Company as an insured and the Secured Party as an additional
insured and loss payee, as its interests may appear, and shall contain a clause
requiring the insurer to give the Secured Party at least fifteen (15) days prior
written notice of any cancellation or lapse of such policy.  If no Event of
Default exists at the time, the Company shall be entitled to use the proceeds of
property damage insurance for the purpose of repairing the damaged property or
replacing it with property of equivalent value.

          SECTION 4.  Certain Covenants as to Equipment.  With respect to any
                      ---------------------------------                      
equipment that may be included in the Collateral the Company shall:

          (a)  Keep its equipment in the places specified therefor on Schedule 3
hereto or, upon 30 days' prior written notice to Secured Party, at such other
places as shall be identified in such notice and which shall be in jurisdictions
where all action required by Section 2 can and shall be taken with respect to
such equipment.

          (b)  Cause its equipment to be maintained and preserved in the same
condition, repair, and working order as when acquired by it, ordinary wear and
tear excepted, and, in the case of any material loss or damage to any of its
equipment, as quickly as practicable after the occurrence thereof, make or cause
to be made all repairs, replacements, and other improvements in connection
therewith which are necessary or desirable to such end.

          (c)  Pay when due all property and other taxes, assessments, and
governmental charges or levies imposed upon it, and all claims (including claims
for labor, materials and supplies) against its equipment except to the extent
the validity thereof is being contested in good faith and adequate reserves
therefor have been maintained.

          (d)  After the occurrence and during the existence of an Event of
Default (as defined in the Note) upon written request of Secured Party, receive
in trust for the benefit of Secured Party, all amounts and proceeds received or

proceeds from other funds of the Company, and forthwith pay such amounts and

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

          (a)  Sell, assign (by operation of law or otherwise), or otherwise
dispose of any of the Collateral except for worn-out or obsolete Collateral or
Collateral disposed of in the ordinary course of business or as permitted in the
Note and/or Asset Purchase Agreement, or any combination of the above.

          (b)  Create or suffer to exist any lien, security interest, or other
charge or encumbrance upon or with respect to any of the Collateral, other than
the lien of the holders of Senior Indebtedness (as defined in the Note) which
lien is senior to the lien of the Secured Party hereunder, except as may be
permitted in the Note and/or Asset Purchase Agreement.

          SECTION 6.  Secured Party's Duties.  The powers conferred on Secured
                      ----------------------                                  
Party hereunder are solely to protect its interest in the Collateral and shall
not impose any duty to exercise any such powers.  Except for the safe custody of
any Collateral in its possession, and the accounting for moneys actually
received by it hereunder, as may be required under applicable law, Secured Party
shall not have any duty as to any Collateral or as to the taking of any
necessary steps to preserve rights against any parties or any other rights
pertaining to any Collateral.

          SECTION 7.  Inspection Rights.  Secured Party at all times shall have
                      -----------------                                        
access, during regular business hours and upon reasonable notice, to inspect and
make extracts from all of the Company's records, files, and books of account
relating to the Collateral, and the Company shall deliver any document or
instrument necessary for Secured Party to obtain records from any service bureau
maintaining records for the Company.  The Company shall, at Secured Party's
request, take all steps necessary to facilitate such inspection, provided such
inspection shall not interfere with the operation of the Company's business.

          SECTION 8.  Remedies.  If any Event of Default (as defined in the
                      --------                                             
Note) shall have occurred and be continuing:

          (a)  Secured Party may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it, all the rights and remedies

                                 Sch. 2.2.3-3
<PAGE>
 
of a secured party on default under the Uniform Commercial Code (the "Code") and
other applicable laws and agreements.

          (b)  Secured Party may (i) require the Company to, and the Company
hereby agrees that it will at its expense and upon request of Secured Party
forthwith, assemble the tangible Collateral as directed by Secured Party and
make it available to Secured Party at a place or places to be designated by
Secured Party which are reasonably convenient to Secured Party and the Company
and (ii) without notice except as specified below or otherwise required by law,
sell the Collateral or any part thereof in one or more parcels at public or
private sale, at any of Secured Party's offices or elsewhere, for cash, on
credit, or for future delivery, and upon such other terms as may be commercially
reasonable.  The Company agrees that, to the extent notice of sale shall be
required by law, at least 10 days' notice to the Company of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification to the Company.  Secured Party shall not be
obligated to make any sale of the Collateral regardless of notice of sale having
been given.  Secured Party may adjourn any public or private sale from time to
time by announcement at the time and place fixed therefor, and such sale may,
without further notice unless required by law, be made at the time and place to
which it was so adjourned.  The Secured Party may petition a court of competent
jurisdiction for a receiver to be appointed in the event of an Event of Default
to the extent permitted by law.

          (c)  All cash proceeds received by Secured Party in respect of any
sale of, collection from, or other realization upon all or any part of the
Collateral shall be applied by Secured Party against the Secured Obligations in
such order as Secured Party shall elect. Any surplus of such cash or cash
proceeds held by Secured Party and remaining after payment in full of all the
Secured Obligations shall be paid over to the Company or to whosoever may be
lawfully entitled to receive such surplus.

          SECTION 9.  Agreement Subject to Subordination Provisions of Note.
                      -----------------------------------------------------  
Notwithstanding anything herein to the contrary, the obligations, covenants and
agreements of the Company set forth in this Agreement are subject to those
provisions of the Note providing for the subordination of the indebtedness
evidenced by the Note to all Senior Indebtedness, as such term is defined in the
Note, and any and all rights of Secured Party set forth herein are expressly
subject to such provisions and to the rights of the holders of Senior
Indebtedness as provided therein.

          SECTION 10.  Amendments, Indulgences, Etc.  No amendment or waiver of
                       ----------------------------                             
any provision of this Agreement nor consent to any departure by the Company
therefrom shall in any event be effective unless the same shall be in writing
and signed by Secured Party and the Company, and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose
for which given.  No failure or delay on the part of Secured Party in the
exercise of any right, power, or remedy under this Agreement shall constitute a
waiver thereof, or prevent the exercise thereof in that or any other instance.

          SECTION 11.  Addresses for Notices.  All notices and other
                       ---------------------                        
communications provided for hereunder shall be given in the manner and to the
addresses specified in the Note.

          SECTION 12.  Continuing Security Interest; etc.  This Agreement shall
                       ----------------------------------                      
create a continuing security interest in the Collateral and shall (a) be binding
upon the Company and its successors and assigns and (b) be binding upon and
inure to the benefit of Secured Party and its successors, transferees, and
assigns.  Without limiting the effect of the foregoing, and notwithstanding any
provision to the contrary contained herein or elsewhere, Secured Party may
assign or transfer the Note and this Security Agreement and any of its rights,
titles and interests hereunder and thereunder, provided, that Secured Party give
notice to the Company of such assignment and the name and address of the
assignee. The execution and delivery of this Agreement shall in no manner impair
or affect any other security (by endorsement or otherwise) for the payment or
performance of the Secured Obligations and no security taken hereafter as
security for payment or performance of the Secured Obligations shall impair in
any manner or affect this Agreement or the security interest granted hereby, all
such present and future additional security to be considered as one general,
continuing security.  Any of the Collateral may be released from this Agreement
without altering, varying, or diminishing in any way this Agreement or the
security interest granted hereby as to the Collateral not expressly released,
and this Agreement and such security interest shall continue in full force and
effect as to all of the Collateral not expressly released.

          SECTION 13.  Governing Law; Code Definitions; Counterparts.  This
                       -------------------------------- -------------      
Agreement shall be governed by and construed in accordance with the laws of the
State of Indiana. Unless otherwise defined herein, terms defined in the Code as
in effect in Indiana on the date hereof (including the terms "equipment,"
"proceeds," and "products") are used herein as therein defined as of such date.
This Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one

                                 Sch. 2.2.3-5
<PAGE>
 
and the same instrument, and any of the parties hereto may execute this
Agreement by signing any such counterpart.

          SECTION 14.  Severability.  The provisions of this Agreement are
                       ------------                                       
independent of and separable from each other, and no such provision shall be
affected or rendered invalid or unenforceable by virtue of the fact that for any
reason any other such provision may be invalid or unenforceable in whole or in
part.

          SECTION 15.  Release.  Upon the payment in full of the Secured
                       -------                                          
Obligations, the security interest granted by the Company in favor of Secured
Party hereunder shall terminate and all rights of Secured Party in and to the
Collateral shall immediately and without the necessity of any further act revert

                                           ---------

<PAGE>
 
remedies available to Landlord, Tenant shall pay as additional rent an amount
equal five percent (5%) of the unpaid payment.

     4.   Taxes.  Tenant shall be liable for all taxes levied against personal
          -----                                                               
property and trade fixtures placed by Tenant in the Demised Premises.  Tenant
shall, during the initial term and any extended term of this Lease, pay before
any interest or penalties begin to accrue, all taxes, assessments, and
governmental charges of any kind and nature whatsoever levied or assessed
against the Demised Premises or any part thereof, including real estate taxes
and other taxes or charges levied in lieu of such taxes, and general and special
public assessments, but not including Landlord's income taxes.  Tenant shall
have the right to contest the real estate tax assessment of the Land and
Building by legal proceedings or in such other manner as Tenant may deem
suitable which, if instituted, Tenant shall conduct promptly at its own cost and
expense, free of any expense to Landlord.  If necessary, the legal proceedings
will be conducted in the name of and with the cooperation of Landlord, and
Landlord shall execute all documents necessary to accomplish the foregoing.  It
is acknowledged that such taxes in the State of Indiana are based on assessments
performed during the year prior to the year in which the taxes based upon such
assessments become due and payable. It is the intention of the parties that
Tenant shall pay such taxes as may become due and payable during Tenant's actual
occupancy of the Demised Premises, regardless of the date of performance of the
assessments upon which such taxes are based.

     5.   Insurance.  Tenant agrees to provide all risk fire and extended
          ---------                                                      
coverage and liability insurance with respect to the Demised Premises, with
coverage equal to 100% of the full replacement cost of the Building (initially
equal to $395,000.00) and in any event sufficient to ensure that neither
Landlord nor Tenant shall be deemed to be a "co-insurer" with respect to the
risks covered by such insurance.  Tenant shall provide liability insurance for
injuries to any person or persons with minimum limits of $1,000,000 for injuries
to one person and $1,000,000 for injuries to more than one person, in one
occurrence or incident.  Tenant may satisfy the foregoing obligations to furnish
insurance through the use of so called "blanket policies" so long as such
coverage provides the same protection as described above. It is agreed to by the
parties that, the above insurance shall be placed by the Tenant with an
insurance company or companies with a rating of not less than "A" as defined and
determined by A.M Best or equivalent rating agency.  Further, said policies or
policies shall name Landlord as an additional insured as its interests may
appear, and no such policy may cancel, expire or terminate without the company
or companies providing Landlord written notice of same at least ten (10) days
prior to such cancellation, expiration or termination.  In the event of such
notice, Tenant shall provide new coverages as described above prior to such
cancellation, expiration or termination.  If Tenant shall fail to provide such
coverages timely, then Landlord may (at its election but not being required to
do so) obtain such coverages with the cost of same being the responsibility of
Tenant.  Failure of Tenant to provide such insurance coverages [or to pay,
within ten (10) days after demand therefor, the cost of same obtained by the

                                       3
<PAGE>
 
Landlord (such demand being considered as additional rent hereunder)] shall be
deemed a material default hereunder.

     6.   Maintenance.  Except for those portions of the Building which Landlord
          -----------                                                           
is to maintain as provided herein, Tenant agrees, at its own expense, to make
all necessary repairs to the Building, including but not limited to, all
interior and exterior portions thereof, and to do all other necessary
maintenance in connection with the Demised Premises while this Lease is in
effect to the end that the Demised Premises are kept and maintained in a good,
safe and attractive condition at all times, normal wear and tear and damage
caused by condemnation or casualty excepted.  Tenant shall be solely responsible
for snow removal, lawn maintenance and garbage removal.  Notwithstanding
anything to the contrary set forth herein, Landlord, and not Tenant, shall bear
the responsibility for (a) maintaining, repairing and replacing the structural
elements (including the roof), slab floor and foundation of the Building in a
good and safe condition, and (b) all material defects and latent construction
defects in the structural elements (including the roof), slab floor and
foundation of the Building.  Landlord shall not be liable to anyone for
interruption in or cessation of any services rendered to the Demised Premises or
Building due to any accident, making of repairs, alterations or improvements,
labor difficulties, trouble in obtaining fuel, or supplies from the sources from
which they are usually obtained, or any cause beyond Landlord's control if such
interruption or cessation shall be for less than three (3) days.  If such
interruption of cessation shall be for more than three (3) days, Tenant may
abate all Base Rent after the first three (3) days and other obligations of
Tenant under this Lease until such time that service returns to normal.    It is
specifically agreed by the parties that Tenant shall solely be responsible for
and shall provide the above described maintenance to all electrical, HVAC,
plumbing and any other mechanical or electrical system in the Demised Premises.
Tenant hereby acknowledges that it has carefully inspected the Demised Premises
and accepts same and all personal property and trade fixtures therein "as is and
where is", except for latent defects.

     7.   Utilities.  Tenant shall pay all charges for heat, water, gas,
          ---------                                                     
electricity and other utilities used or consumed on the Demised Premises.

     8.   Destruction Of Premises.  a.  In the event the Building or any part
          -----------------------                                            
thereof, shall, during the term of this Lease, be destroyed or damaged by fire,
explosion, the elements or other casualty, Tenant shall give prompt notice
thereof to Landlord.  Landlord and Tenant shall determine the extent of any
damage or destruction (and the time required to repair the damage) within thirty
(30) days after the occurrence of such damage or destruction.

          b.   If the damage or destruction renders the Building untenantable
for Tenant's intended use (in Tenant's judgment, exercised commercially
reasonably), then Tenant may terminate this Lease by written notice to Landlord,
Landlord shall be entitled to receive any proceeds payable out of the all risk
fire and extended coverage insurance to be provided by Tenant pursuant to
Section 5 (without claim of Tenant),

                                       4

and thereupon this Lease shall terminate, and the parties shall have no further
obligation hereunder except Tenant's obligation to pay the rental and other
charges and obligations accrued to the date of such damage.

          c.   If the damage or destruction:

               (1)  renders the Building untenantable for Tenant's intended use
                    (in Tenant's judgment, exercised commercially reasonably),
                    and Tenant does not chose to terminate this Lease; or
                                    ---                                  

               (2)  does not, in Tenant's judgment, exercised commercially
                         ---                                              
                    reasonably, render the Building untenantable for Tenant's
                    intended use;

then, in either such event, Landlord, shall, at Landlord's cost, utilizing its
best efforts and due speed and diligence, proceed to build, rebuild or repair
the Building to substantially the same condition in which the Building existed
prior to such damage or destruction; provided, however, that Landlord shall only
                                     --------  -------                          
be required to build, rebuild or repair to the extent that the proceeds from the
all risk fire and extended coverage insurance to be provided by Tenant pursuant
to Section 5 are made available to Landlord. Base Rent shall be equitably
abated during the period of such building, rebuilding and repair by an amount
proportionate to the area of the Building rendered unusable by Tenant.

     9.   Eminent Domain.  In the event the Building or a portion of the
          --------------                                                
Building and/or the Land is taken under the power of eminent domain for any
public or quasi-public use so as to render the Building and/or the Land
untenantable for Tenant's intended use (in Tenant's judgment, exercised
commercially reasonably), then this Lease shall terminate effective upon the
earlier of the date Tenant thereafter vacates the Demised Premises or the date
that the condemning authority takes possession of the condemned property and,
thereupon, both parties shall be relieved of any further obligation under this
Lease, except that the parties shall fulfill all of their obligations hereunder
to be performed to the date of such termination.  In the event that a portion of
the Building and/or the Land is so taken, but this Lease is not terminated and
canceled as above provided, then the rent thereafter becoming due hereunder
after the date of such taking shall be reduced to a reasonable sum proportionate
to the value of the Demised Premises after the condemnation.

     All condemnation proceeds with respect to the Demised Premises shall be the
sole property of Landlord.  Tenant hereby waives all rights to any award in
condemnation, including, without limitation, rights arising from termination of
all or any part of Tenant's leasehold interest.  Tenant may, however, file a
separate claim for its leasehold improvements, trade equipment, machinery and
fixtures and relocation expenses but not for the value of the unexpired balance
of the term or its leasehold interest.

                                       5

     10.  Alterations.  a.  Landlord agrees that Tenant may, at its own expense,
          -----------                                                           
from time to time during the term hereof, make such interior alterations and
changes in and to the Demised Premises, as it finds necessary or convenient for
its purposes, provided that such interior alterations or changes shall not
lessen the value of the Building.  Any such alterations or changes and any new
structures therein shall remain with the Demised Premises at the end of the term
of this Lease, or any renewal term hereof, and shall be considered as
improvements to and become a part of the real estate of Landlord.  Tenant agrees
that any alterations, or changes aforesaid made by it will be erected or made in
a first-class, workmanlike manner and all shall be subject to the terms and
conditions of this Lease.  Any alterations or changes having a cost in excess of
$10,000 must be approved in writing by the Landlord prior to being made, such
approval shall not be unreasonably withheld or unduly delayed.

          b.   Notwithstanding anything contained in Section 10.a hereof, all
trade equipment, machinery and trade fixtures placed in and upon the Demised
Premises by Tenant during the term of this Lease shall be and remain personal
property belonging to Tenant, and, at the expiration of the term of this Lease,
or any renewal hereof, Tenant shall have the right to remove such personal
property from the Demised Premises, restoring and repairing, at its expense, any
damage to the Demised Premises directly caused by the removal of such items of
personal property.

     11.  Landlord's Access.  During Tenant's normal business hours, and
          -----------------                                             
provided such entry does not unreasonably interfere with Tenant's business
operations, Landlord and its agent may enter upon the Demised Premises (but only
if accompanied by a representative of Tenant) after reasonable notice to Tenant
(a) to exhibit the Demised Premises during the last six (6) months of this
Lease, or (b) for the purpose of maintaining, repairing and inspecting the same,
or (c) showing said Demised Premises to prospective purchasers or lenders.

     12.  Indemnity.  Tenant shall, to the extent not covered by the liability
          ---------                                                           
insurance herein described, indemnify, pay and save harmless Landlord from all
liability for damages or injury to any person, firm or corporation occasioned by
or resulting from all occurrences or incidents on the Demised Premises during
the term of this Lease, except if caused by the negligence or fault of Landlord
or its agents and employees.

     13.  Quiet Enjoyment and Permitted Use.  Landlord warrants that Tenant, so
          ---------------------------------                                    
long as no default has occurred and is then continuing under this Lease beyond
applicable notice and/or cure periods, shall have peaceful possession and quiet
enjoyment of the Demised Premises during the term of this Lease and that Tenant
may use the same for a day care center (the "Permitted Use") and for any other
lawful purpose.  Tenant's use of the Demised Premises shall not violate any
ordinance, law or regulations of any Governmental Authority.  All signs and the
location thereof shall be furnished at the sole cost and expense of Tenant, and
shall be subject to the prior approval of Landlord, such approval not to be
unreasonably

                                       6
<PAGE>
 
withheld or unduly delayed.  Landlord expressly acknowledges that Tenant is
entering into this Lease in reliance upon its ability to conduct the Permitted
Use in compliance with all applicable ordinances, laws and regulations, and
without any limitation or restriction whatsoever by reason of any provision or
restriction which exists as of the date hereof and affected the Demised Premises
(any such limitation or restriction being called a "Restriction").  Landlord
hereby represents and warrants to Tenant that, to the best of Landlord's
knowledge, information and belief, (i) the Demised Premises is currently in
compliance with all such ordinances, laws and regulations which apply or pertain
to the Demised Premises or Tenant's use therein, and (ii) there are no
Restrictions as of the date of this Lease which apply or pertain to the Demised
Premises or Tenant's use therein.  With respect to any present Restrictions,
Landlord agrees to indemnify, defend and hold Tenant harmless from and against
all liability, obligation, claims, suits, expenses, including reasonable
attorney's fees, damages or loss including any civil or (to the extent permitted
by law) criminal fine or penalty incurred or suffered by Tenant by reason of
Landlord's breach of the foregoing warranty.

     14.  Assignment and Subletting.  a.  Except for a "Permitted Transaction"
          -------------------------                                           
(as defined below), Tenant shall not assign, mortgage, pledge or encumber this
Lease or sublet the Building, in whole or part, without the prior written
consent of Landlord, which consent may not be unreasonably withheld or unduly
delayed.  For the purposes of this Section, any mortgage, conveyance, transfer
or encumbrance of this Lease and any transfer by operation of law, other than a
Permitted Transaction, shall be deemed an assignment.

          b.   Tenant may assign this Lease or sublet the Building, in whole or
in part, without Landlord's consent, to a Related Party (as defined below) (such
assignment or subletting, a "Permitted Transaction"). The term "Related Party"
shall mean the following persons or entities:

               (1)  an "Affiliate" of Tenant, which term is defined as a
                    subsidiary, parent or subsidiary of a parent of Tenant. A
                    "subsidiary" is a corporation fifty percent (50%) of whose
                    voting stock is owned by another corporation, which latter
                    corporation is referred to as a "parent";

               (2)  a successor to Tenant by (3) merger or consolidation, or (4)
                    acquisition of all or substantially all of the assets or
                    stock of Tenant; or

               (5)  an Affiliate of any of the entities described in Section
                    14.b.(2) above.

          c.   In the event of any assignment or subletting with the written
consent of Landlord (or in the event of any Permitted Transaction), Tenant will
nevertheless remain liable for the performance of all of the terms, conditions
and

                                       7
<PAGE>
 
covenants of this Lease. In the event of any Permitted Transaction, Tenant will
nevertheless remain liable for the performance of all of the terms, conditions
and covenants of this Lease.  Any permitted assignment or subletting (other than
a Permitted Transaction) shall be by agreement in form and content reasonably
acceptable to Landlord.

     During any period that Tenant remains liable as assignor-guarantor
hereunder, Tenant shall not be bound by any amendment or modification of this
Lease unless Tenant shall have specifically consented thereto in writing.
Landlord shall notify all guarantors of all failures of performance on the part
of the assignee-in-possession which, with the passage of time could ripen into a
default, within thirty (30) days after such failure of performance occurs,
whether or not Landlord has given the assignee-in-possession notice of such
failure.  Following the assignee-in-possession's failure to cure the default,
any guarantor shall be accorded an additional period of five (5) days in the
case of monetary failures and fifteen (15) days in the case of non-monetary
failures (or such longer period of time as may be necessary to cure such non-
monetary failure, so long as such guarantor is proceeding, with due diligence,
to cure such non-monetary failure to comply) in which to cure said failures.

          d.   Consent by Landlord to any assignment (other than a Permitted
Transaction) shall not constitute a waiver of the necessity for such consent to
any subsequent assignment.  If the Premises be occupied by anyone other than
Tenant, whether as assignee, concessionaire or otherwise, Landlord may collect
rent from such occupant and apply the net amount collected to the rent reserved
under this Lease but acceptance of such rent shall not be deemed a consent to
any such occupancy by any such other party.  Any consent by Landlord to any
assignment of this Lease (other than a Permitted Transaction, as to which no
such consent shall be required) may be conditioned upon the assignee assuming
the full and faithful performance of all the terms and conditions of this Lease
and upon the continued liability of Tenant under all the terms hereof.

     15.  Default.  If Tenant shall fail to pay to Landlord the rent and/or
          -------                                                          
other sums of money payable to Landlord as and when due and payable hereunder
and such default shall continue for a period of ten (10) days after written
notice thereof shall be given to Tenant by Landlord, or in the case Tenant shall
fail to comply with any other provisions or conditions of this Lease, upon its
part to be kept and performed, and such default shall continue for a period of
thirty (30) days (or such longer period of time as may be necessary to cure such
non-compliance, so long as Tenant is proceeding, with due diligence, to cure
such nonmonetary failure to comply) after written notice thereof shall be given
to Tenant by Landlord, or if Tenant shall be adjudged bankrupt, or shall make an
assignment for the benefit of creditors, or if a receiver of any property of
Tenant in or upon said Demised Premises or for all or part of Tenant's interest
hereunder be appointed in any action, suit or proceeding, by or against Tenant
and such adjudication, assignment or appointment (unless voluntary) shall not be
vacated or annulled within ninety (90) days, or if the interest of Tenant in the
Demised Premises shall be sold under execution, or other legal process, it shall
be

                                       8
<PAGE>
 
lawful for Landlord, to terminate this Lease and to remove Tenant from
possession of the Demised Premises, and again have, repossess and enjoy the same
as if this Lease had not been made, and everything herein contained on the part
of Landlord to be done and performed shall cease and determine.  The foregoing
rights are without prejudice, however, to the right of Landlord to recover from
Tenant all damages incurred by Landlord as result of Tenant's breach and
additionally Landlord may retake possession of and relet said Demised Premises
for the remainder of said term and may recover from Tenant any deficiency
between the amount so obtained and the rent herein reserved plus all costs
incurred by Landlord as a result of Tenant's default, including without
limitation attorneys' fees, brokerage commissions and remodeling fees; provided,
however, Landlord shall be obligated in such event to make a good faith effort
to mitigate its damages.  Landlord hereby confirms its acknowledgement and
agreement that, except as set forth in the Asset Purchase Agreement identified
below and the Security Agreement and Financing Statements forming a part
thereof, it shall have no right of distraint and no right, title or interest
(including, without limitation, any landlord's lien) in or to any trade
equipment, machinery, trade fixtures, or any other personal property placed upon
the Demised Premises by Tenant or any permitted sublessee, assignee, or
occupant.  It is acknowledged by the parties that this Lease is being entered
into simultaneously with other lease agreements between the parties or their
affiliates.  Attached hereto as and incorporated herein by reference as Exhibit
C is a listing of all of the other lease agreements referenced above.  Further,
in connection with the execution of this Lease and the above referenced other
lease agreements, the parties have executed a Asset Purchase Agreement dated as
of August __, 1995, and other related documents, including the Buyer's
Transaction Documents (as defined in the Asset Purchase Agreement).  It is
agreed to by the parties hereto that in the event of a default by Tenant beyond
applicable notice and/or cure periods, if any, in any of the Buyer's Transaction
Documents or any one or more of the other lease agreements, as set forth on
Exhibit C, then, at the election of Landlord, this Lease shall be in default and
all of the rights and remedies of Landlord as set forth herein shall apply to
this Lease, any and all of the other leases listed on Exhibit C and any of the
Buyer's Transaction Documents.  It is the intention of the parties that there be
a cross-default provision in each of the documents referenced above so that if
there is a default in any one or more such documents beyond applicable notice
and/or cure periods, if any, then, at the election of the Landlord, all or any
of those documents may also be held in default.

     16.  Non Waiver.  No failure to insist on performance in any instance of
          ----------                                                         
any obligation hereunder shall be deemed a waiver of such performance, or any
subsequent performance of such obligation or of the performance of any other
obligation hereunder, and no waiver in any instance of the performance of any
obligation hereunder shall be deemed a waiver of any subsequent performance of
such obligation or of the performance of any other obligation hereunder.

     17.  Notices.  For all purposes hereunder, including the payment of
          -------                                                       
rentals, the addresses of the parties hereto are as follows:

                             Tenant:
                             
                             President
                             Nobel Education Dynamics, Inc.

                             1400 North Providence Road, Suite 3055
                             Media, PA  19063

     Either party may change the foregoing address by notice to the other party
given pursuant to this Section.  All notices required or permitted under this
Lease shall be in writing and shall be given by either certified or registered
mail, return receipt requested, or by express, overnight courier (such as
Federal Express).  Notice given by mail as provided above shall be effective
three (3) days after mailing.  Notice given by express, overnight courier shall
be effective the day after delivery to the courier.

     18.  Subordination.  This Lease and all of the rights of Tenant hereunder
          -------------                                                       
are and shall be subject and subordinate to the lien of any deed of trust,
mortgage or mortgages, now or hereinafter placed on the Demised Premises or any
part thereof, and to any and all renewals, modifications, consolidations,
replacements, extensions or substitutions of any such deeds of trust, mortgage
or mortgages (all of which are hereinafter termed the mortgage or mortgages);
provided, however, that as a condition to such subordination, each holder of
each or all of such mortgages shall enter into a non-disturbance agreement, in
form and content reasonably acceptable to both Tenant and such holder, to the
effect that so long as Tenant is not in default under this Lease, or any renewal
hereof, no foreclosure of the lien of said mortgage or of any other proceeding
in respect thereof shall divest, impair, modify, abrogate, or otherwise
adversely affect any interests or rights whatsoever of Tenant under the said
Lease.  Landlord agrees to obtain from the holders of all existing mortgages
which are senior or superior to Tenant's interest in the Demised Premises under
this Lease a non-disturbance agreement in form acceptable to Tenant, and the
obtaining of such agreement(s) shall be a condition precedent to the validity
and effectiveness of Tenant's obligations under this Lease.

     19.  Liens.  If, because of any act or omission of Tenant or anyone
          -----                                                         
claiming through or under Tenant, any mechanic's or other lien or order for the
payment of money shall be filed against the Demised Premises, Tenant shall, at
its expense, cause the same to be canceled and discharged of record within
thirty (30) days after the date of filing thereof, or file an appropriate bond,
satisfactory to Landlord, in the exercise

                                      10
<PAGE>
 
of commercial reasonableness, which will cause such lien to be discharged as a
lien against the Demised Premises, or deliver to Landlord adequate security,
acceptable to Landlord, in the exercise of commercial reasonableness, for the
discharge thereof, and shall also indemnify and hold harmless Landlord from and
against any and all costs, expenses, claims, losses and damages, (including
reasonable attorneys' fees) in connection therewith.

     20.  Landlord's Default; Additional Representations and Covenants.
          ------------------------------------------------------------ 

          a.   Landlord shall be in default hereunder if Landlord shall fail to
perform any of its obligations under this Lease within thirty (30) days (ten
(10) days in the case of monetary obligations owed by Landlord to Tenant) after
receipt of written notice from Tenant specifying such failure unless the
intrinsic nature of such failure is such that it cannot reasonably be cured
within thirty (30) days in which case Landlord shall have the additional time
reasonably necessary to cure such failure, provided Landlord commences to cure
the failure within such thirty (30) day period and proceeds with diligence and
continuity.  If Landlord fails to cure, then Tenant may, at its option, in
addition to any other remedies at law or equity, incur any expense necessary to
perform the obligations of Landlord specified in such notice and deduct such
expense from the rent and other charges becoming due hereunder.

          b.   Landlord represents and warrants that:

               (1)  Landlord is the fee simple owner of the Building and Leased
Premises;

               (2)  Landlord has full right, power and authority to make,
execute and deliver this Lease;

               (3)  there are no agreements, restrictions, covenants,
encumbrances or easements which will increase any of Tenant's obligations under
this Lease or diminish any of Tenant's rights hereunder.

     21.  Integration.  It is expressly understood and agreed by and between the
          -----------                                                           
parties hereto that this Lease sets forth all the promises, agreements,
conditions and understandings between Landlord and/or its agents and Tenant
relative to the Demised Premises and that there are no oral promises,
agreements, conditions or understandings between the parties with respect
thereto.

     22.  Successors and Assigns.  This Lease and all the covenants, provisions
          ----------------------                                               
and conditions herein contained shall be inure to the benefit of and be binding
upon the parties hereto and their respective heirs, personal representatives,
successors and permitted assigns. Without limiting the effect of the foregoing,
and notwithstanding any provision to the contrary contained herein or elsewhere,
Landlord may assign or transfer this Lease or any amounts to be paid to Landlord
hereunder. Further, Landlord may, in its sole discretion, sell or convey the
real estate which is the subject

                                      11
<PAGE>
 
of this Lease, provided, that the new owner of the real estate shall purchase or
obtain the same subject to the terms and conditions of this Lease. In the event
of an assignment or transfer of this Lease or the sale or conveyance of the real
estate, as described above, then the new holder or owner shall become the
substitute Landlord and is subject to perform all of the duties of "Landlord"
hereunder. Further, in such event, the "Landlord" assigning or transferring this
Lease or selling or conveying the real estate shall be fully released by the
Tenant, and Tenant shall look solely to the new holder or owner for the
performance, of any obligation which accrued or occurred under this Lease.

     23.  Partial Invalidity.  If any term, covenant or condition of this Lease
          ------------------                                                   
or the application thereof to any person or circumstance shall to any extent be
invalid or unenforceable, the remainder of this Lease or the application of such
term, covenant or condition of this Lease shall be valid and enforceable to the
fullest extent permitted by law.

     24.  Headings and Interpretation.  The paragraph headings used throughout
          ---------------------------                                         
this instrument are for convenience and reference only, and words contained
therein shall in no way be held to explain, modify, amplify or aid in the
interpretation, construction, or meaning of the provisions of this Lease.
Whenever herein the masculine gender is used, the same shall include the
feminine and neuter gender.

     25.  Personal Property Financing.  Subject to and in accordance with the
          ---------------------------                                        
terms and conditions of the Asset Purchase Agreement and the Security Agreement
and Financing Statements forming a part thereof, Tenant may finance some or all
of Tenant's trade fixtures, equipment and furnishings which are located at the
Demised Premises.  In this regard, except as set forth in the Asset Purchase
Agreement and the Security Agreement and Financing Statements forming a part
thereof, Landlord agrees that it shall have no lien on such trade fixtures,
equipment and furnishings and that any claim which Landlord may have against
such property shall be and remain junior and inferior to the claim of any third
party providing financing to Tenant for the acquisition of such property.

     26.  Hazardous Substances.  Tenant will comply with all federal, state and
          --------------------                                                 
local environmental laws, rules, regulation and statutes applicable to Tenant's
use and occupancy of the Demised Premises during the term of this Lease.

     Tenant shall not cause or permit any Hazardous Material (as hereinafter
defined) to be brought upon, kept, or used in or about the Demised Premises by
Tenant, its agents, employees, contractors, or invitees, except for such
Hazardous Material as is necessary to Tenant's business.

     Any Hazardous Material permitted on the Demised Premises as provided in
this Section, and all containers therefor, shall be used, kept, stored, and
disposed of in a manner that complies with all federal, state and local laws or
regulations applicable to such Hazardous Material.

               a.   Promptly following the Closing, Buyer, the Company and
Sellers (and their respective affiliates) shall use their best efforts to enable
Sellers promptly to prepare or cause to be prepared, in accordance with United
States generally accepted accounting principles ("GAAP") applied on a basis
consistent with that used in the preparation of the Company's financial
statements referenced in Section 5.12 hereof except as otherwise provided in
                                                                            
Schedule B hereto, a consolidated balance sheet of the Company as of the Closing
----------                                                                      
Date (as herein defined).

                                      -2-
<PAGE>

Such balance sheet prepared and finally determined as provided in this Section
2.2 is referred to herein as the "Closing Statement."  Within 30 days following
the Closing, Sellers shall deliver to Buyer a final draft of the Closing
Statement, together with a calculation of Adjusted Net Worth (as herein defined)
as of the Closing Date.  For the purposes of this Agreement, "Adjusted Net
Worth" shall mean the consolidated assets of the Company, less its consolidated
liabilities, in each case as determined in accordance with GAAP applied on a
basis consistent with that used in the preparation of the Company's financial
statements referenced in Section 5.12 hereof except as otherwise provided in
Schedule B hereto.
----------        

               b.   If Buyer shall have any objections to the Closing Statement
or to the calculation of Adjusted Net Worth, Buyer and Sellers shall attempt in
good faith to reach an agreement as to the matter in dispute. If Buyer and
Sellers shall have failed to resolve such disputed matter within thirty (30)
business days after receipt of notice of such objection, then any such disputed
matter may, at the instance of Buyer or Sellers, be submitted to and determined
by an accounting firm acceptable to Sellers and Buyer (the "Auditors"). The
definitive Closing Statement and calculation of Adjusted Net Worth shall be
audited by the Auditors in accordance with GAAP applied on a basis consistent
with that used in the preparation of the Company's financial statements
referenced in Section 5.12 hereof except as otherwise provided in Schedule B
                                                                  ----------  
hereto and shall be final, binding and conclusive on all parties hereto. Buyer,
Company and Sellers shall cooperate fully with such audit, and shall use best
efforts to cause their respective affiliates so to cooperate, so as to cause the
Auditors to complete such audit within 30 days after commencement of such audit.
The fees and expenses of such audit shall be divided equally between Buyer and
Sellers.

          3.   Post-Closing Adjustment.
               ----------------------- 

               a.   If the Adjusted Net Worth as of the Closing Date as
conclusively determined as provided herein (such conclusive determination is
referred to herein as "Certified Adjusted Net Worth") is less than $400,000 (the
"Minimum Net Worth"), then each Seller shall pay, or cause to be paid, to Buyer
an amount of such deficiency which is proportionate to his or her allocable
share of the Purchase Price. If the Certified Adjusted Net Worth is greater than
the Minimum Net Worth, then Buyer shall pay to each Seller their proportionate
share of such excess amount. Any payment pursuant to this Section shall be made
within five business days following receipt by the parties of the final Closing
Statement and the Certified Adjusted Net Worth calculation.

                                      -3-
<PAGE>
 
               b.   Notwithstanding Section 2.3(a), if Buyer and Sellers dispute
any portion of the Closing Statement or the calculation of Certified Adjusted
Net Worth, but nonetheless agree that, following final determination of
Certified Adjusted Net Worth, a payment will be required to be made pursuant to
Section 2.3(a), the amount of such payment which the parties do not dispute
shall be paid.

               c.   Amounts payable pursuant to this Section 2.3 by Sellers
shall be made by certified check or wire transfer of immediately available funds
to an account designated by the Buyer or, at Buyer's option, by the release to
Buyer of such number of Withheld Shares (as defined in Section 12.5(a) hereof)
equal to the amount payable to Buyer pursuant to this Section 2.3 divided by the
Guaranteed Value Per Share (as defined in Section 11.5 hereof). Amounts payable
pursuant to this Section 2.3 by Buyer shall be made by certified check to
Sellers at their respective addresses set forth on Schedule A hereto.
                                                   ----------

                  --------                                                      
the Company at any time.

          4.   Millbrook Facility.  The parties acknowledge and agree that the
               ------------------                                             
Company and the owner of the facility leased by the Company for the Company's
operation of the Millbrook Country Day School located in Raleigh, North Carolina
are currently negotiating the proposed renovation of that facility or the
construction of a new facility on the existing site.  The parties also
acknowledge and agree that a third party may construct a new facility on a
different site in close proximity to the present site.  Sellers covenant and
agree that on or before August 15, 1996, either the renovation of the facility
or the construction of a new facility (at the present site or at another site in
close proximity to the present site) will be completed (such completion to be
evidenced by the delivery to the Company and Buyer of a certificate of occupancy
or other similar instrument), in each case to the satisfaction of the Company
and Buyer.  If the foregoing covenant is not satisfied by August 15, 1996, the
Sellers will forfeit the 93,750 Nobel Shares held in escrow pursuant to Section
12.5 hereof.  Buyer agrees to negotiate in good faith with the owner of such
facility the terms and conditions of the lease of such facility prior to the
construction of the facility.  The terms and provisions of the lease on the new
facility shall be essentially as set forth in the lease provided for the North
Raleigh school site, in the form attached as Exhibit 4.1(h), with the exception
                                             --------------                    
of the commencement date, termination date, property description, and lease
rental rate.  The lease rate on the facility shall be such that after taking
into account the total costs of construction and ground acquisition, the annual
rental rate shall be equal to the greater of (A) the annual debt service
(principal and interest) on the project based upon a 20-year amortization
schedule, provided that the annual interest rate shall not exceed thirteen
percent (13%), or (B) sixteen percent (16%) of total tuition and registration
fees actually received from the facility.  If the new facility is built on the
current location, the rental rate on the facility shall be the greater of (A)
the annual debt service (principal and interest) on the costs of

                                     -28-
<PAGE>
 
construction (excluding land) based upon a 20-year amortization schedule,
provided that the annual interest rate shall not exceed thirteen percent (13%),
plus $36,000 per year representing the land value or (B) sixteen percent (16%)
of the total tuition and registration fees actually received from the facility.

          5.   Guaranteed Value of Nobel Shares.  In the event that during the
               --------------------------------                               
Effectiveness Period (as defined in Section 13.2(a) hereof) a Seller sells any
Nobel Shares in bona fide Brokers' Transactions (as defined in Section
13.2(i)(8) hereof) at a price less than $1.60 per share (such price, as
appropriately adjusted for any stock dividends, stock splits or similar events,
shall be hereinafter referred to as the "Guaranteed Value Per Share"), then
Buyer shall pay to such Seller the difference between the Guaranteed Value Per
Share and the actual sales price (excluding commissions, fees and other charges
related to such sale) for the Nobel Shares actually sold by such Seller;
                                                                        
provided that the Sellers shall not sell in the aggregate more than 70,000 Nobel
--------                                                                        
Shares during any 30-day period during the Effectiveness Period.  Amounts
payable by Buyer pursuant to this Section 11.5 shall be made by certified check
within 30 days of Buyer's receipt of the written confirmation statement from the
selling broker.

                          SECTION L.  INDEMNIFICATION

          1.   Indemnification by Sellers.  Sellers shall, jointly and
               --------------------------  
severally, indemnify and hold Buyer and its officers, directors and shareholders
harmless against and in respect of any and all losses, costs, expenses, claims,
damages, obligations and liabilities, including interest, penalties and
reasonable attorneys fees and disbursements (collectively, "Damages"), which
Buyer or any such person may suffer, incur or become subject to arising out of,
based upon or otherwise in respect of: (a) any inaccuracy in or breach of
representations or warranties of the Company or any Seller made in or pursuant
to this Agreement or any Sellers' Transaction Document; (b) any breach or non-
fulfillment of any covenant or obligation of the Company or any Seller contained
in this Agreement or any Sellers' Transaction Document; (c) any matters required
to be disclosed on the Disclosure Schedule pursuant to Section 5.11 but not
disclosed; (d) all liabilities of the Company for or with respect to any Taxes
for which consolidated or combined returns are filed (whether or not reserved
against or contested) for taxable periods up to and including the Closing Date;
(e) all liabilities and obligations (whether known or unknown, disclosed or
undisclosed, and whether absolute, accrued, contingent or otherwise) of the
Company existing on the Closing Date, except for Current Liabilities,
liabilities and obligations of the Company reflected on the Balance Sheet and
liabilities and obligations of the Company disclosed on the Disclosure Schedule
which expressly relate to Sections 5.7, 5.9, 5.13(c), 5.14(a),

                                     -29-
<PAGE>
 
5.15(a), 5.15(c), 5.17 and 5.26 hereof; and (f) the presence, use, handling,
generation, processing, treatment, storage, transportation, release, discharge
or disposal of any Hazardous Substances on, about, or beneath any of the Real
Properties by any person on or prior to the Closing Date, regardless of whether
the related claim is asserted prior to, on or after the Closing Date.

          2.   Indemnification by Buyer.  Buyer shall indemnify and hold Sellers
               ------------------------                                         
harmless against and in respect of any and all Damages which Sellers may suffer,
incur or become subject to arising out of, based upon or otherwise in respect of
: (a) any inaccuracy in or breach of any representation or warranty of Buyer
made in or pursuant to this Agreement or any Buyer's Transaction Document; (b)
any breach or nonfulfillment of any covenant or obligation of Buyer contained in
this Agreement or any Buyer's Transaction Document; and (c) the operation of the
Company after the Closing Date.

          3.   Notice; Control of Defense.  Any party (for this purpose the
               --------------------------                                  
Sellers jointly and severally being one party and Buyer being the other party)
seeking indemnification hereunder (an "Indemnified Party") shall promptly notify
in writing the other party from whom such indemnification is sought (an
"Indemnifying Party") of the assertion of any claim or the discovery of any fact
upon which the Indemnified Party intends to base a claim for indemnification
hereunder.  With respect to any claim made by a third party against which an
Indemnified Party is seeking indemnification hereunder, the Indemnifying Party
shall have the right, at its own expense, to participate in or assume  thereof
from the Indemnified Party, and the Indemnified Party shall fully cooperate with
the Indemnifying Party subject to 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 to assume control or otherwise participate
in the defense of any third-party claim after receipt of notice thereof from the
Indemnified Party, the Indemnifying Party, in the absence of gross negligence or
willful misconduct on the part of the Indemnified Party, shall be bound by the
results obtained by the Indemnified Party with respect to such claim.

          4.   Limitations.
               ----------- 

               a.   All claims for breach of any representation or warranty made
by any party must be asserted prior to the second anniversary of the Closing
Date, and no party shall be entitled to indemnity hereunder or other relief at
law or in equity for any such claims asserted after that date; provided,
                                                               --------  
however, that in the case of income and other tax claims and environmental
-------      
claims, claims may be made within the period of the applicable statute of
limitations provided that neither party takes, nor

                                     -30-
<PAGE>
 
permits to be taken, any action to extend such period of limitations without the
other's written consent in advance.  This Section 12.4 shall not impose any time
limitation on the assertion of claims for indemnification under Section 12.1(b),
(c) or (e) or Section 12.2(b) or (c).

               b.   With respect to any claim for indemnification under this
Section 12 arising out of, based upon or otherwise in respect of any inaccuracy
in or breach of representations or warranties, the Indemnified Party shall not
be entitled to indemnification hereunder unless and until the aggregate of all
valid claims of the Indemnified Party for such indemnification exceeds the sum
of $25,000 (the "Threshold"), provided that once the Threshold has been
exceeded, the Indemnified Party shall be entitled to recover the full amount of
its valid claims hereunder, not just the amount in excess of the Threshold.

               c.   The liability of each Seller hereunder shall not exceed the
Purchase Price (including the Nobel Shares) paid to such Seller by Buyer for
such Seller's Educo Shares.

          5.   Escrow.
               -------

                    a.   At Closing, Sellers will deliver to Buyer as escrow
agent (the "Escrow Agent") certificates representing 93,750 Nobel Shares duly
endorsed in blank by Sellers (such shares, the "Withheld Shares"). The Withheld
Shares shall be held by Escrow Agent in escrow, and Buyer is hereby granted a
security interest in such shares, as security for Sellers' timely performance of
(i) Sellers' obligations under Section 2.3 hereof ("Obligations"), (ii) the
covenant set forth in Section 11.4 hereof or (iii) Sellers' obligation to
indemnify Buyer under this Section 12 against any Damages that Buyer may suffer,
incur or become subject to. If it is finally determined (either by agreement of
the parties, by judgment of a court of competent jurisdiction or by award of an
arbitrator) that an amount is owed to Buyer in respect of any matters described
in the immediately preceding sentence, Buyer shall have the right to have
transferred into its name that number of Withheld Shares as is equal to the
quotient obtained by dividing (a)(i)the dollar amount of such Damages or
Obligations, as the case may be, or (ii) $150,000 in the event of the breach of
the covenant set forth in Section 11.4 hereof by (b) the Guaranteed Value Per
Share (as defined in Section 11.5 hereof). The Escrow Agent shall notify Sellers
promptly of the transfer to Buyer of any Withheld Shares.

                    b.   Any Withheld Shares not transferred to Buyer hereunder
shall be delivered by the Escrow Agent to Sellers' Escrow Agent if the covenant
set forth in Section 11.4 is satisfied in accordance with its terms, provided
                                                                     --------
that if on or before the satisfaction of the covenant set forth in Section 11.4

                                     -31-
<PAGE>
 
the Buyer has given written notice to Sellers of any claim or claims by Buyer
hereunder, the Escrow Agent shall continue to withhold such number of the
Withheld Shares as is equal to the estimated total dollar amount of such claim
or claims, calculated as specified in subsection (a), until there has been a
final determination as to the claim.

                    c.   Sellers shall not transfer or convert any of the
Withheld Shares, or any interest therein, or make any other pledge of the
Withheld Shares, so long as the Withheld Shares are held in escrow hereunder.

                    d.   Unless and until Withheld Shares become the property of
Buyer as above provided, any cash dividend thereon shall be delivered, as paid,
to the Seller owning such Shares. In the case of any stock dividend, stock split
or similar event, the additional shares shall be added to the Withheld Shares,
and an appropriate adjustment shall be made in the Guaranteed Value Per Share.
Except as provided in this Section 12.5, all other rights incident to the
Withheld Shares, including voting rights, shall be in Sellers.

          6.   Remedies Not Exclusive.  The indemnification obligations
               ----------------------   
contained in this Section 12 are not intended to waive or preclude any other
claims, rights or remedies which may exist at law (whether statutory or
otherwise) or in equity with respect to the matters covered hereby, except that
the Withheld Shares shall be Buyer's sole remedy against Sellers in the event of
the breach of the covenant set forth in Section 11.4 hereof.


                        SECTION M.  SECURITIES MATTERS

          1.   Investment Representations and Covenants of Sellers.
               ---------------------------------------------------

                    a.   Sellers understand that the issuance of the Nobel
Shares will not be registered under the Securities Act of 1933, as amended (the
"1933 Act"), on the grounds that the issuance of the Nobel Shares is exempt from
registration pursuant to Section 4(2) of the 1933 Act and/or Regulation D
promulgated under the 1933 Act ("Regulation D"), and that the reliance of Buyer
on such exemptions is predicated in part on the Sellers' representations,
warranties, covenants and acknowledgements set forth in this Section.

                    b.   Sellers hereby represent and warrant to Buyer that they
are Accredited Investors, as that term is defined in Regulation D, and that the
Nobel Shares will be acquired by them for their own account, not as a nominee or
agent, for investment and without a view to resale or other distribution within
the meaning of the 1933 Act, and the rules and regulations

                                     -32-
<PAGE>
 
thereunder, and Sellers will not distribute any of the Nobel Shares in violation
of the 1933 Act.

                    c.   Sellers:  (i) acknowledge that the Nobel Shares are not
registered under the 1933 Act and must be held indefinitely by Seller unless the
Nobel Shares are subsequently registered under the 1933 Act (in accordance with
the provisions of Section 13.2 hereof or otherwise) or an exemption from
registration is available, (ii) are aware that any routine sales of the Nobel
Shares made under Rule 144 of the SEC under the 1933 Act may be made only in
limited amounts and in accordance with the terms and conditions of that Rule and
that in such cases where the Rule is not applicable, registration or compliance
with some other registration exemption will be required, (iii) are aware that
Rule 144 is not presently, and for a period of at least two years following the
Closing Date hereof probably will not be, available for use by Sellers for
resale of the Nobel Shares, and (iv) are aware that Buyer is not obligated to
register any sale, transfer or other disposition of the Nobel Shares except in
accordance with the provisions of Section 13.2 hereof.

                    d.   Sellers represent and warrant to Buyer that Sellers
have such knowledge and experience in financial and business matters that they
are fully capable of evaluating the risks and merits of Sellers' investment in
the Nobel Shares.

                    e.   Sellers acknowledge receipt of the SEC filings and
materials referred to in Section 6.8 hereof and confirm and acknowledge that:
(i) Buyer has afforded Sellers the opportunity to ask questions of and receive
answers from Sellers' officers and various directors concerning the terms and
conditions of this Agreement and Sellers' investment in the Nobel Shares and to
obtain such additional information as the Sellers have requested, and (ii)
Sellers have availed themselves of such opportunity to the extent they deem
necessary and have received the information requested.

                    f.   In order to ensure compliance with the provisions of
subsection (b) hereof, each Seller covenants and agrees that, after the Closing,
he or she, as the case may be, will not sell, transfer or otherwise dispose of
any of the Nobel Shares or any interest therein (unless such sale, transfer or
disposition has been registered under the 1933 Act in accordance with the
provisions of Section 13.2 hereof or otherwise) or otherwise without there first
having been compliance with either of the following conditions:

                         (1)  Buyer shall have received a written opinion of
          counsel in form and substance reasonably satisfactory to Buyer, or a
          copy of a "no-action" or interpretive letter of the SEC, specifying
          the nature

                                     -33-
<PAGE>
 
          and circumstances of the proposed transfer and indicating that the
          proposed transfer will not be in violation of any of the provisions of
          the 1933 Act and the rules and regulations promulgated thereunder; or

                         (2)  Buyer shall have received an opinion from its own
          counsel to the effect that the proposed transfer will not be in
          violation of any of the provisions of the 1933 Act and the rules and
          regulations promulgated thereunder.

               g.   Each Seller also acknowledges and agrees that the
certificates representing the Nobel Shares issuable to him or her will contain a
restrictive legend noting the restrictions on transfer described in this Section
13 and under federal and applicable state securities laws, and that appropriate
"stop-transfer" instructions will be given to Buyer's stock transfer agent.

          2.   Registration of Nobel Shares.
               ---------------------------- 

               a.   Registration Statement.  Within ten (10) business days after
                    ----------------------                                      
the Closing Date, Buyer shall prepare and file with the Securities and Exchange
Commission (the "SEC") a registration statement of Form S-3 (the "Registration
Statement") under the 1933 Act to permit the offer and sale of the Nobel Shares
(which term, for the purposes of this Section 13.2, shall include any securities
into which or for which the Nobel Shares subsequently may be converted or
exchanged) by the Sellers from time to time through the facilities of the
National Association of Securities Dealers Automated Quotation System at market
prices current at the time of sale or in other transactions at negotiated
prices; provided, however, that the Sellers agree that they will not sell in the
        -----------------                                                       
aggregate more than 70,000 Nobel Shares during any 30-day period during the
Effectiveness Period (as hereinafter defined).  Buyer shall use reasonable
efforts to cause the Registration Statement to be declared effective promptly
and, except as set forth below, to remain effective under the 1933 Act for 18
months thereafter, and will prepare and file with the SEC any amendments or
post-effective amendments as may be necessary to keep the Registration Statement
effective under the 1933 Act during that period.   Buyer will promptly notify
the Sellers in writing of the date on which the Registration Statement is
declared effective.  Notwithstanding the foregoing, Buyer shall not be obligated
to keep the Registration Statement or any prospectus included therein (the
"Prospectus") current during any period (A) of up to 90 days per calendar year
if Buyer's chief executive officer advises the Sellers that he has determined in
good faith that valid business reasons make doing so inadvisable, provided that
the Effectiveness Period shall be extended for such number of days that the
Prospectus is not kept current pursuant to this clause

                                     -34-
<PAGE>
 
(A), or (B) when financial statements do not satisfy the requirements of the
last sentence of paragraph (b) of Rule 3-12 of Regulation S-X (or any successor
rule) to the extent, and only to the extent, that the SEC interprets such
sentence as being applicable to the continued effectiveness of the Registration
Statement, provided Buyer uses reasonable efforts to satisfy such requirements
as soon as possible.  For purposes of this Agreement, the "Effectiveness Period"
shall be the period during which the Prospectus is kept current pursuant to the
provisions of this Section 13.2(a).

               b.   Copies of Documents.  During the Effectiveness Period, Buyer
                    -------------------                                         
shall furnish to the Sellers such number of copies of the Registration
Statement, the Prospectus (including each preliminary Prospectus) and any
amendments and supplements thereto and any documents incorporated by reference
in the Registration Statement as the Sellers shall reasonably request.

               c.   Blue Sky Compliance.  Buyer shall use reasonable efforts to
                    -------------------                                        
register or qualify or cooperate with the Sellers in connection with the
notification, coordination, registration or qualification (or use reasonable
efforts to obtain exemption from such registration or qualification) of the
Nobel Shares under the securities or blue sky laws of such jurisdictions in the
United States as the Sellers reasonably shall request, up to a maximum of five
states, and do any and all other acts and things which may be reasonably
necessary to enable the Sellers to consummate the disposition of the Nobel
Shares in such jurisdictions during the Effectiveness Period; provided, that in
no event shall Buyer be required to qualify to do business as a foreign
corporation in any jurisdiction where it is not so qualified, to subject itself
to taxation in any jurisdiction where it has not theretofore done so or to take
any action which would subject it to general service of process in any such
jurisdiction where it is not then so subject.

               d.   Notification.  During the Effectiveness Period, Buyer shall
                    ------------                                               
notify the Sellers promptly (i) of any request by the SEC for amendments or
supplements to the Registration Statement or a Prospectus or for additional
information relating thereto, (ii) of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement or the initiation of
any proceedings for that purpose, (iii) of the receipt by Buyer of any
notification with respect to the suspension of the registration, qualification
or exemption from registration or qualification of any of the Nobel Shares
covered by the Registration Statement for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose and (iv) of the
happening of any event which makes any statement made in the Registration
Statement or in the Prospectus or any document incorporated therein by
reference, or

                                     -35-
<PAGE>
 
deemed to be incorporated therein by reference, untrue in any material respect
or which requires the making of any changes in the Registration Statement or the
Prospectus so that such documents will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

               e.   Supplements and Post-Effective Amendments.  Subject to the
                    -----------------------------------------                 
provisions of the last sentence of Section 13.2(a) above, during the
Effectiveness Period, upon the occurrence of any event contemplated by clause
(i) or (iv) of Section 13.2(d) above, Buyer will prepare a post-effective
amendment to the Registration Statement or a supplement to the Prospectus or any
document incorporated therein by reference or file any other required document
so that, as thereafter delivered to the purchasers of the Nobel Shares being
sold thereunder, the Prospectus will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

               f.   Listing.  Buyer shall use reasonable efforts to cause all of
                    -------                                                     
the Nobel Shares covered by the Registration Statement to be listed on each
securities exchange, if any, on which similar securities issued by Buyer are
then listed, provided that the applicable listing requirements are satisfied.

               g.   Correspondence with the SEC.  Buyer shall, upon request from
                    ---------------------------                                 
a Seller, deliver promptly to the Seller copies of all correspondence between
the SEC and Buyer, its counsel or auditors, and all memoranda relating to
discussions with the SEC or its staff with respect to the Registration
Statement.

               h.   Stock Certificates.  Buyer will cooperate with the Sellers
                    ------------------                                        
to facilitate the timely preparation and delivery of certificates representing
Nobel Shares sold under the Registration Statement, which certificates shall not
have any restrictive legends.

               i.   Obligations of the Sellers.  Following the filing of the
                    --------------------------                              
Registration Statement and during any period that the Registration Statement is
effective, each Seller shall:

                    (1)  not effect any stabilization transactions or engage in
any stabilization activity in connection with shares of Common Stock of Buyer in
contravention of Rule 10b-7 under the 1933 Exchange Act of 1934, as amended (the
"Exchange Act");

                    (2)  furnish each broker through whom the Seller offers
Nobel Shares such number of copies of the

<PAGE>
 
Prospectus as the broker may require and otherwise comply with the prospectus
delivery requirements under the 1933 Act;

                    (3)  report to Buyer each month all sales, pledges and other
dispositions of Nobel Shares made by the Seller during said month;

                    (4)  not, and shall not permit any Affiliated Purchaser (as

purchase for any account in which the Seller has a beneficial interest, or
attempt to induce any other person to purchase, any shares of stock of Buyer in
contravention of Rule 10b-6 under the Exchange Act;

                    (5)  not offer or agree to pay, directly or indirectly, to
anyone any compensation for soliciting another to purchase, or for purchasing
(other than for the Seller's own account), any securities of Buyer on a national
securities exchange in contravention of Rule 10b-2 under the Exchange Act;

                    (6)  cooperate with Buyer as Buyer fulfills its obligations
under Section 13.2(c) above;

                    (7)  furnish such information concerning the Seller as Buyer

Act (collectively, "Brokers' Transactions"); and

                    (9)  not sell under the Registration Statement during any
period after Buyer has provided notice to the Seller pursuant to Section
13.2(d)(iv) above and until Buyer provides to the Seller notice that the
Registration Statement no longer fails to state a material fact required to be
stated therein, or no longer misstates a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
made not misleading.

               (j)  Expenses.  Buyer shall bear all expenses incident to Buyer's
                    --------                                                    
performance of or compliance with this Section 13.2, including all registration

          (k)  Indemnification.
               --------------- 

               (1)  Indemnity by Buyer.  Buyer shall (i) indemnify and hold
                    ------------------     
harmless each Seller (each such person being hereinafter referred to in this
Section 13.2(k)(1) as an "Indemnified Party") against any losses, claims,
damages, liabilities or expenses ("Losses"), to which each such Indemnified
Party may become subject, under the 1933 Act or otherwise, insofar as such
Losses (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in the
Registration Statement or underlying Prospectus, as amended or supplemented if
Buyer has furnished any amendments or supplements thereto, or any document filed
under a state securities or blue sky law (each such document individually being
referred to as a "Registration Document" and collectively as "Registration
Documents") or insofar as any Losses (or actions in respect thereof) arise out
of or are based upon the omission or alleged omission to state in any
Registration Document or underlying Prospectus, as amended or supplemented if
Buyer has furnished any amendments or supplements thereto, a material fact
required to be stated therein or necessary to make the statements made therein
(in the case of a Prospectus, in the light of the circumstances under which they
were made), not misleading, and (ii) reimburse each Indemnified Party for all
legal or other expenses reasonably incurred by it in connection with
investigating or defending any Loss, including any amounts paid in settlement of
any litigation, commenced or threatened, if such settlement is effected with the
prior written consent of Buyer; provided, that Buyer shall not be liable for any
Losses arising out of or based upon any untrue statement or omission made in any
Registration Document in reliance upon and in conformity with written
information furnished to Buyer by or on behalf of a Seller stating that it is
for use in the preparation of the Registration Document; and provided further,
that Buyer shall not be liable to a particular Indemnified Party with respect to
any such Prospectus, as amended or supplemented, to the extent that the Loss
arises from the sale of any Nobel Shares by such Indemnified Party to the person

                                     -38-
<PAGE>
 
asserting Loss and to which there was not sent or given, within the time
required by the 1933 Act, a copy of such Prospectus as then amended or
supplemented, if Buyer has previously furnished copies thereof to such
Indemnified Party and such Prospectus as then amended or supplemented has
corrected the misstatement or omission at issue.

               (2)  Indemnity by the Sellers.  Each Seller shall (i) indemnify
                    ------------------------   
and hold harmless Buyer, any officer, director, employee or agent of Buyer, and
each other person, if any, who controls Buyer within the meaning of Section 15
of the 1933 Act (each such person being hereinafter referred to in this Section
13.2(k)(2) as an "Indemnified Party") against any Losses to which each such
Indemnified Party may become subject under the 1933 Act or otherwise, insofar as
such Losses (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Document, or arise out of or are based upon the omission or
alleged omission to state in any Registration Document a material fact required
to be stated therein or necessary to make the statements made therein (in the
case of a prospectus, in the light of the circumstances under which they were
made,) not misleading, and (ii) reimburse each Indemnified Party for all legal
or other expenses reasonably incurred by it in connection with investigating or
defending any such Losses or action, including any amounts paid in settlement of
any litigation, commenced or threatened, if such settlement is effected with the
prior written consent of the Seller; provided, that such indemnification or
reimbursement shall be payable only if, and to the extent that, any Losses arise
out of or are based upon an untrue statement or omission made in any
Registration Document in reliance upon and in conformity with written
information furnished to Buyer by the Seller specifically stating that it is for
use in the preparation thereof.

               (3)  Procedure for Indemnification.  Promptly after receipt by an
                    -----------------------------                               
Indemnified Party (as defined under Sections 13.2(k)(1) or 13.2(k)(2), as the
case may be) of notice of the commencement of any action, the Indemnified Party
shall notify the party from whom indemnification is being sought (the
"Indemnifying Party") in writing of the commencement thereof, if a claim in
respect thereof is to be made against an Indemnifying Party under this Section
13.2(k); provided, that the omission of such notice shall not relieve the
Indemnifying Party from liability which it may have to the Indemnified Party
under this Section 13.2(k), except to the extent that the Indemnifying Party is
actually prejudiced by such failure to give notice, and shall not relieve the
Indemnifying Party from any liability which it may have to any Indemnified Party
otherwise than under this Section 13.2(k).  In case any action is brought
against the Indemnified Party and it shall notify the Indemnifying Party of the
commencement thereof, the Indemnifying Party shall be

                                     -39-
<PAGE>
 
entitled to participate in, and to the extent that it chooses, to assume the
defense thereof with counsel reasonably satisfactory to the Indemnified Party,
and after notice from the Indemnifying Party to the Indemnified Party that it so
chooses, the Indemnifying Party shall not be liable for any legal or other
expenses subsequently incurred by the Indemnified Party in connection with the
defense thereof; provided, that (i) if the Indemnifying Party fails to take
reasonable steps necessary to defend diligently the claim within 20 days after
receiving notice from the Indemnified Party that the Indemnified Party believes
the Indemnifying Party has failed to diligently defend such claim, or (ii) if
the Indemnified Party who is a defendant in any action or proceeding which is
also brought against the Indemnifying Party reasonably shall have concluded that
there are legal defenses available to the Indemnified Party which are not
available to the Indemnifying Party, or (iii) if representation of both parties
by the same counsel is otherwise inappropriate under applicable standards of
professional conduct, then the Indemnified Party shall have the right to assume
or continue its own defense as set forth above.  In no event, however, shall the
Indemnifying Party be responsible for the fees of more than one firm of counsel
for all Indemnified Parties.

               (4)  Non-Exclusive Indemnity.  Any indemnity agreements contained
                    ------------------------ 
in this Section 13.2(k) shall be in addition to any other rights to
indemnification or contribution which any Indemnified Party may have pursuant to
law or contract and shall remain operative and in full force and effect
regardless of any investigation made or omitted by or on behalf of any
Indemnified Party.

               (5)  Contribution.  If for any reason the foregoing indemnity is
                    ------------                                               
unavailable, or is insufficient to hold harmless an Indemnified Party, then the
Indemnifying Party shall contribute to the amount paid or payable by the
Indemnified Party as a result of such Losses (i) in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party on the one
hand and the Indemnified Party on the other (determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Indemnifying Party or the Indemnified Party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission), or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law or provides a
lesser sum to the Indemnified Party than the amount hereinafter calculated, in
such proportion as is appropriate to reflect not only the relative fault of the
Indemnifying Party and the Indemnified Party, but also the relative benefits
received by the Indemnifying Party on the one hand and the Indemnified Party on
the other, as well as any other relevant equitable

                                     -40-
<PAGE>
 
considerations.  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.


                            SECTION N.  TERMINATION

          1.   Termination.   This Agreement may be terminated at any time prior
               -----------                                                      
to the Closing by:

               a.   Buyer, if the conditions set forth in Section 9 hereof have
not been satisfied by the Closing Date;

               b.   Buyer pursuant to Section 16.5(b) hereof;

               c.   Sellers, if the conditions set forth in Section 10 hereof
have not been satisfied by the applicable date or the Closing Date; or

               d.   mutual consent of Buyer and the Sellers.

          2.   Effect of Termination.
               --------------------- 

               a.   If Buyer terminates this Agreement pursuant to Section 16.5,
or if a party terminates this Agreement because one of its conditions precedent
has not been fulfilled, or if this Agreement is terminated by mutual consent,
this Agreement shall become null and void without any liability of any party to
the other, provided, however, that: (i) if such termination is by Sellers
pursuant to Section 14.1(c) as a result of a breach by Buyer of any of its
representations, warranties or covenants in this Agreement, or if such
termination is by Buyer pursuant to Section 7.2 (other than as a result of a
breach by the Company or Sellers of any of their representations, warranties or
covenants in this Agreement), the Deposit Money, together with all interest
thereon, shall be paid to and retained by the Sellers as liquidated damages and
the Buyer shall have no further liability to the Sellers by reason of such
breach (retention of the Deposit Money with interest being Sellers' exclusive
remedy for Buyer's breach of this Agreement); and (ii) if such termination is by
Buyer pursuant to Section 14.1(a) as a result of a breach by the Company or
Sellers of any of their representations, warranties or covenants in this
Agreement, Buyer shall be entitled to recover its damages and to the return of
the Deposit Money and all interest thereon.  In all other cases where this
Agreement is terminated and the Deposit Money is not required to be paid to
Sellers, the Deposit Money, together with all interest thereon, shall be
returned to Buyer.

<PAGE>
 
               b.   Nothing in this Section 14 shall affect either party's right
to specific performance of the other parties' obligations hereunder.

               c.   The provisions of Section 7.1(b) shall survive the
termination of this Agreement.


            SECTION O.  REPRESENTATION OF SELLERS BY SELLERS' AGENT

          1.   Appointment of Sellers' Agent.
               ----------------------------- 

                    a.   Each of the Sellers (herein called the "Represented
Sellers") hereby irrevocably appoints Richard V. McCool (herein called the
"Sellers' Agent") as such Represented Sellers' agent and attorney-in-fact to
take any action required or permitted to be taken by such Represented Seller
under the terms of this Agreement, including, without limiting the generality of
the foregoing, the execution, delivery and receipt of any notices, certificates
or other documents (including without limitation the Escrow Agreement) to be
executed, delivered or received by or on behalf of any or all of the Represented
Sellers, the payment of expenses relating to the transactions contemplated by
this Agreement, the preparation of the Closing Statement and the agreement of
the Represented Sellers as to Certified Adjusted Net Worth as provided in
Section 2.2 hereof, the representation of the Represented Sellers in the
resolution of any disputed matters hereunder or under the Escrow Agreement and
in indemnification proceedings hereunder, and the right to waive, modify or
amend any of the terms of this Agreement and the Escrow Agreement.  Each
Represented Seller agrees to be bound by any and all actions taken by the
Sellers' Agent on such Represented Seller's behalf.  The Represented Sellers
agree jointly and severally to indemnify the Sellers' Agent from and against and
in respect of any and all liabilities, damages, claims, costs and expenses,
including but not limited to attorneys' fees, arising out of or due to any
action as the Sellers' Agent and any and all actions, proceedings, demands,
assessments or judgments, costs and expenses incidental thereto, except to the
extent that the same result from bad faith or gross negligence on the part of
the Sellers' Agent.

                    b.   The Buyer and the Deposit Escrow Agent shall be
entitled to rely exclusively upon any communications given by the Sellers' Agent
on behalf of any Represented Seller and shall not be liable in any manner
whatsoever for any action taken or not taken in reliance upon the actions taken
or not taken or communications made by the Sellers' Agent. The Buyer and the
Deposit Escrow Agent shall be entitled to disregard any notices or
communications given or made by Represented Sellers unless given or made through

          2.   Successor Agent.  In the event of the death or resignation of the
               ---------------                                                  
Sellers' Agent or his inability to perform his functions hereunder, the
Represented Sellers shall promptly appoint a new agent or agents as attorney-in-
fact or attorneys-in-fact, and such appointment or appointments shall be deemed
to have been made when communicated to the Buyer in writing signed by the former
holders (or the personal representatives thereof) of at least 51% of the Educo
Shares owned by Represented Sellers immediately prior to the Closing Date.  If
the Represented Sellers do not within fifteen days appoint a new agent or
agents, then the Represented Seller then living who previously owned the
greatest number of Educo Shares outstanding immediately prior to the Closing
Date shall serve as Sellers' Agent if he or she is able and willing to do so,
until a successor agent or agents shall have been appointed in accordance with
the provisions hereof.

          3.   Sellers' Actions.  The manner and form by which the Represented
               ----------------                                               
Sellers shall decide upon any new agent and attorney-in-fact shall be decided
solely by the former holders (or the personal representatives thereof) of at
least 51% of the Educo Shares owned by Represented Sellers outstanding
immediately prior to the Closing Date.  The Represented Sellers recognize, and
hereby acknowledge, that the Sellers' Agent has an interest in the subject
matter of this Agreement and that the appointment of such Agent (which shall
include any person who becomes the Sellers' Agent pursuant to the provisions of
Section 15.2 above) as the Sellers' Agent constitutes an irrevocable power-of-
attorney coupled with an interest.


                           SECTION P.  MISCELLANEOUS

          1.   Survival of Representations and Warranties.  All representations,
               ------------------------------------------                       
warranties, covenants and agreements made by Buyer and the Sellers (but not the
Company) in this Agreement or in any schedule, certificate, document or list
delivered by any such party pursuant hereto shall survive the Closing and
notwithstanding any investigation conducted before or after the Closing Date or
the decision of any party to complete the Closing, each party hereto shall be
entitled to rely upon the representations and warranties of the other party.

          2.   Best Efforts.  Sellers and Buyer shall use their respective best
               ------------                                                    
efforts with respect to matters within their control to cause the transactions
contemplated by this Agreement to be consummated.

with respect to this Agreement or the transactions contemplated herein shall be
at such time and in such manner as Sellers and Buyer shall agree, provided that
nothing herein shall

                                     -43-
<PAGE>
 
prevent either party upon notice to the other from making such public
announcements as such party's counsel may consider advisable in order to satisfy
that party's legal and contractual obligations in such regard.

          4.   Costs and Expenses.  Any and all costs and expenses (including,
               ------------------

paragraph (a) above or (ii) the destruction or condemnation before the Closing
Date of any portion of the Real Properties such that a school or pre-school, as
the case may be, cannot be carried out at such location for a period of more
than seven days, Buyer may at its option terminate this Agreement, whereupon the
Deposit Money (including all interest thereon) shall be returned to Buyer and
this Agreement shall become null and void without any liability of any party to
the other.

          6.   Performance.  In the event of a default, either party shall have
               -----------                                                     
the right, in addition to any other remedies which may be available, to obtain
specific performance of the terms of this Agreement.  Should any party default
in performance of any of the terms and conditions of this Agreement or any other
agreement referred to herein which results in the filing of a lawsuit for
damages, specific performance, or other remedy, the prevailing party in such
lawsuit shall be entitled to its reasonable attorney's fees and court costs from
the losing party.

          7.   Benefit and Assignment.  This Agreement will be binding upon the

parties hereto.  Prior to Closing, none of the parties hereto may assign its
interest under this Agreement to any other person without the prior consent of
the other parties.

                  FIRST AMENDMENT TO STOCK PURCHASE AGREEMENT

          THIS FIRST AMENDMENT TO STOCK PURCHASE AGREEMENT is dated as of August
31, 1995, by and among Educo, Inc., a Maryland corporation (the "Company"), the
record and beneficial owners of all of the outstanding shares of capital stock
of the Company listed on Schedule A hereto (each, a "Seller," and collectively,
                         ----------                                            
the "Sellers") and Nobel Education Dynamics, Inc., a Delaware corporation
("Buyer").  The Stock Purchase Agreement dated May 23, 1995, between the parties
shall be hereinafter referred to as the "Agreement."  All capitalized terms not
otherwise defined herein shall have the same meanings as are ascribed to them in
the Agreement.

                                   BACKGROUND

     A.   Pursuant to Section 2.1(b) of the Agreement, at Closing the amount
payable by Buyer to Sellers or Sellers' Agent is $1,950,000 and the amount
payable by Buyer to Sellers' Escrow Agent is $50,000. The Sellers have decided
that they desire to increase the amount payable to Sellers' Escrow Agent to
$75,000 thus reducing the amount payable to Sellers or Sellers' Agent to
$1,925,000.

     B.   Pursuant to Section 2.1(c) of the Agreement, Buyer is to issue and
deliver the Nobel Shares at Closing, and pursuant to Section 13.2 of the
Agreement, Buyer is to cause the Registration Statement to filed within ten (10)
business days after the Closing Date.  Buyer and Sellers have decided that it is
in their mutual best interests to modify the Agreement to provide for two
installment payments of the Purchase Price with (i) the cash portion of
$2,000,000 paid at Closing and (ii) the issuance and delivery of the Nobel
Shares occurring on January 15, 1996.

     C.   Pursuant to Section 4.1(p) of the Agreement, the Sellers are obligated
to deliver, or cause to be delivered, to the Buyer at Closing "a letter of
intent addressed to the Company and signed by or on behalf of the owner of the
facility leased by the Company for the Company's operation of the North Raleigh
Country Day School ... [pursuant to which] such owner will ... construct
additional classroom(s) at the site..." Such owner has already agreed to
construct such additional classroom(s), and the parties wish to amend the
Agreement to reflect the terms and conditions pursuant to which such additional
classroom(s) shall be leased to the Company.

     D.   Pursuant to Section 4.1(q) of the Agreement, the Sellers are obligated
to deliver, or cause to be delivered, to the Buyer at Closing "releases of the
Company from all guarantees of indebtedness or other obligations of third
parties, including without limitation those guarantees listed on the Disclosure

                                     - 1 -
<PAGE>
 
Schedule (as hereafter defined) in connection with Sections 5.7 and 5.12(c)" of
the Agreement.

     E.   The Sellers are unable to deliver, or cause to be delivered to the
Buyer at Closing a release of the Company from a certain portion of such
indebtedness; namely, that certain Small Business Administration (SBA) Guaranty
dated June 10, 1987 (the "SBA Guaranty"), from the Company and certain other
guarantors to and for the benefit of the Small Business Administration (the
"SBA") in order to induce the SBA to make a loan in the amount of $153,000 (the
"Loan") to ILM Joint Venture, a North Carolina general partnership ("ILM").

     F.   Pursuant to Section 4.1(h) of the Agreement, the Sellers are obligated
to deliver, or cause to be delivered, to the Buyer at Closing, the Leases.

     G.   The Buyer is willing to release Seller from its obligation to deliver
to the Buyer at Closing a release of the Company from the SBA Guaranty; SUBJECT
                                                                        -------
TO THE CONDITION PRECEDENT that the Lease (the "Wilmington Lease") pertaining to
--------------------------                                                      
the Wilmington, North Carolina, property (e.g., Early Childhood Learning Center,
                                          ----                                  
ILM Joint Venture, Wilmington, North Carolina) be amended:

          1.     to provide for a reduction of $1,000 in each monthly
installment of Annual Basic Rent for the first 12 monthly installments of the
lease term (representing an aggregate reduction of $12,000); and

          2.   to permit the tenant under the Wilmington Lease to offset,
against Annual Basic Rent and any and all other sums that may become due and
payable under the Wilmington Lease, any and all sums paid or costs incurred by
the Company under or pursuant to the SBA Guaranty.


          NOW THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements herein contained, the
parties hereto, intending to be legally bound, agree as follows:

     1.   Section 2.1(b) of the Agreement is hereby amended by replacing the
ninth word on the twelfth line of such Section with the following "$1,925,000"
and by replacing the last word of such Section with the following "$75,000" and

fourth and fifth words on the first line of such Section with the following "on
January 15, 1996".

                 SECOND AMENDMENT TO STOCK PURCHASE AGREEMENT

          THIS SECOND AMENDMENT TO STOCK PURCHASE AGREEMENT is dated August 31,
1995, by and among Educo, Inc., a Maryland corporation (the "Company"), the
record and beneficial owners of all of the outstanding shares of capital stock
of the Company listed on Schedule A hereto (each, a "Seller," and collectively,
                         ----------                                            
the "Sellers") and Nobel Education Dynamics, Inc., a Delaware corporation
("Buyer").  The Stock Purchase Agreement dated May 23, 1995, between the
parties, as amended by the First Amendment to Stock Purchase Agreement dated
August 31, 1995, shall be hereinafter referred to as the "Agreement." All
capitalized terms not otherwise defined herein shall have the same meanings as
are ascribed to them in the Agreement.

                                   BACKGROUND

     A.   Pursuant to Section 5.9 of the Agreement, the Sellers represented and
warranted to Buyer, among other things, that "no Permit will be adversely
affected by the consummation of the transactions contemplated by this
Agreement."

     B.   The Sellers have subsequently discovered that the operating permit
(the "Existing Millbrook Permit") for the facility currently leased by the
Company for the Company's operation of the Millbrook Country Day School in
Raleigh, North Carolina (the "Existing Millbrook Facility") may be adversely
affected by the consummation of the transactions contemplated by this Agreement.

     C.   Section 11.4 of the Agreement sets forth certain rights and
obligations of the parties after Closing with respect to the Existing Millbrook
Facility and the possible replacement of the Existing Millbrook Facility with a
new facility (the "New Millbrook Facility") on a different site in close
proximity to the Existing Millbrook Facility.

     D.   The parties wish to amend the Agreement to reflect the rights and
obligations of the parties with respect to the Existing Millbrook Permit, the
Existing Millbrook Facility and the New Millbrook Facility.

          NOW THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements herein contained, the
parties hereto, intending to be legally bound, agree as follows:

     1.   Schedule A of the Agreement is hereby amended and restated in its
entirety in the form attached to this Amendment.

     2.   Section 2.1(b) of the Agreement is hereby amended and restated in its
entirety as follows:

                                     - 1 -
<PAGE>
 
     (b) At the Closing, Buyer shall deliver: (i) to Sellers or Sellers' Agent
(as defined in Section 16.16 hereof), as the case may be, the aggregate amount
of One Million Eight Hundred Thousand Dollars ($1,800,000), by wire transfer
pursuant to instructions previously given by Sellers to Buyer for that purpose
in the respective amounts set forth beside each Seller's name on Schedule A
hereto, such that the aggregate amount payable at the Closing to Sellers or
Sellers' Agent shall equal $1,725,000 and the amount payable at the Closing to
Sellers' Escrow Agent shall equal $75,000 and (ii) to Escrow Agent (as defined
in Section 12.5 hereof) $200,000 pursuant to Section 12.5 hereof.

     3.   Section 5.9 of the Agreement is hereby amended to insert the phrase
"except as disclosed in Section 11.4," immediately prior to the phrase "no
Permit will be adversely affected by the consummation of the transactions
contemplated by this Agreement."

     4.   Section 11.4 of the Agreement is hereby amended and restated in its
entirety as follows:

          "11.4.   Millbrook Facility.
                   ------------------ 

               11.4.1.  The parties acknowledge and agree that the operating
permit (the "Existing Millbrook Permit") for the facility currently leased by
the Company for the Company's operation of the Millbrook Country Day School in
Raleigh, North Carolina (the "Existing Millbrook Facility") may be adversely
affected by the consummation of the transactions contemplated by this Agreement.

               11.4.2.  Buyer is currently negotiating in good faith with the
owner of the Existing Millbrook Facility (the "Millbrook Owner") the terms and
conditions of a lease (the "New Millbrook Lease") pursuant to which the
Millbrook Owner would construct and lease to Buyer a new facility (the "New
Millbrook Facility") on a different site in close proximity to the Existing
Millbrook Facility. The terms and provisions of the New Millbrook Lease shall be
essentially as set forth in the lease provided for the North Raleigh school
site, in the form attached as Exhibit 4.1(h), with the exception of the
commencement date, termination date, property description, and lease rental
rate. The lease rate on the New Millbrook Facility shall be such that after
taking into account the total costs of construction and ground acquisition, the
annual rental rate shall be equal to the greater of (A) the annual debt service
(principal and interest) on the project based upon a 20-year amortization
schedule, provided that the annual interest rate shall not exceed thirteen
percent (13%), or (B) sixteen percent (16%) of total tuition and registration
fees actually received from the New Millbrook Facility. If the New Millbrook
Facility is built on the current

                                     - 2 -
<PAGE>
 
location, the rental rate on the New Millbrook Facility shall be the greater of
(A) the annual debt service (principal and interest) on the costs of
construction (excluding land) based upon a 20-year amortization schedule,
provided that the annual interest rate shall not exceed thirteen percent (13%),
plus $36,000 per year representing the land value or (B) sixteen percent (16%)
of the total tuition and registration fees actually received from the New
Millbrook Facility.

          11.4.3.  At Closing, Sellers shall place in escrow, pursuant to
Section 12.5 of this Agreement, (a) $200,000 in cash (the "Withheld Cash"), and
(b) certificates representing 125,000 Nobel Shares duly endorsed in blank by
Sellers (such shares, the "Withheld Shares"). The Withheld Cash shall be held in
an interest-bearing account, and all interest earned thereon shall follow the
principal.

          11.4.4.  Sellers covenant and agree that on or before August 15, 1996,
the construction of the New Millbrook Facility will be completed (such
completion ("Completion") to be evidenced by the delivery to the Company and
Buyer of a certificate of occupancy or other similar instrument and operating
permit for the New Millbrook Facility in such period of time as to permit Buyer
to move its operations from the Existing Millbrook Facility to the New Millbrook
Facility without any interruption in operations), in each case to the
satisfaction of the Company and Buyer.

          11.4.5.  Sellers covenant and agree that the Existing Millbrook Permit
shall remain in full force and effect and shall not be revoked prior to
Completion.

          11.4.6.  If the Existing Millbrook Permit is revoked prior to
commencement of construction of the New Millbrook Facility (such commencement
("Commencement") to be evidenced by the installation of footings and
foundations), then:

               (a)  the Escrow Agent shall immediately transfer to Buyer 62,500
of the Withheld Shares (but shall retain the remaining 62,500 Withheld Shares
for further disposition in accordance with the terms hereof);

               (b)  if Completion subsequently occurs on or before August 15,
1996, then, upon such Completion, the Escrow Agent shall transfer to Sellers the
remaining 62,500 Withheld Shares; and

               (c)  if Completion does not subsequently occur on or before
                                       ---
August 15, 1996, then, on August 16, 1996, the Escrow Agent shall transfer to
Buyer the remaining 62,500 Withheld Shares; PROVIDED, HOWEVER, that, if
                                            --------  -------

that

                                     - 3 -

then the performance dates set forth in this Section 11.4.6(c) shall be extended
for a commercially reasonable period of time to permit the correction of such
non-material items.

          11.4.7.  If the Existing Millbrook Permit is not revoked, but
Commencement does not occur on or before August 15, 1996, then, on August 16,
1996, the Escrow Agent shall transfer (a) to Buyer 93,750 of the Withheld Nobel
Shares held in escrow pursuant to Section 12.5 hereof, and (b) to Sellers all of
the Withheld Cash, together with the remaining 31,250 Withheld Shares held in
escrow pursuant to Section 12.5 hereof; PROVIDED, HOWEVER, that, if Completion
                                        --------  -------

such Completion, the Escrow Agent shall transfer to Sellers all of the Withheld
Shares held in escrow pursuant to Section 12.5 hereof.

          11.4.10. If, after Commencement occurs, the Existing Millbrook Permit
is not revoked, but Completion does not occur on or before August 15, 1996,
                                    ---

substantially performed except for minor, non-material items that will not
materially adversely affect Buyer's use of the New Millbrook Facility, then the
performance dates set forth in this Section 11.4.10 shall be extended for a
commercially reasonable period of time to permit the correction of such non-
material items.

          11.4.11. If, after Commencement occurs, the Existing Millbrook Permit

          11.4.12.  A graphic representation of the terms and conditions of this

          "12.5     At Closing, Sellers will deliver to Buyer as escrow agent
(the "Escrow Agent") (a) the Withheld Cash, and (b) the Withheld Shares duly
endorsed in blank by Sellers. The Withheld Shares shall be held by Escrow Agent

security for Sellers' timely performance of (i) Sellers' obligations under
Section 2.3 hereof ("Obligations"), (ii) the covenants set forth in Section 11.4
hereof (the "Millbrook Covenants"), or (iii) Sellers' obligation to indemnify
Buyer under this Section 12 against any Damages that Buyer may suffer, incur or

                              Any Withheld Shares not transferred to Buyer
hereunder shall be delivered by the Escrow Agent to

                       select an appraiser who shall each determine a value;

               (ii)    If the values determined by such two appraisers are the
                       same (or the lower value determined by an appraiser is
                       within one percent of the value determined by the other),
                       then such value (or the average of such two values) shall
                       be the Appraised Value;

               (iii)   If the foregoing two appraisals are not the same and the
                       lower value determined by an appraiser differs by more
                       than one percent of the value determined by the other,
                       then the appraisers shall together select a third
                       appraiser to determine a value;

               (iv)    If the determination of the third appraiser is greater
                       than the largest of the first two appraisals or less than
                       the smallest of the first two appraisals, then the

                       Appraised Value; and

<PAGE>
 
           (v) If the determination of the third appraiser is between the first
               two appraisals, then the average of the third appraisal and the
               closest of the first two appraisals shall be the Appraised Value.

Each party shall pay the fees and costs of the appraiser it selects, and the
fees and costs of the third appraiser, if any, shall be paid equally by Company
and the Lenders.

           (c) Remedies.  Failure to comply with the terms of the put right set
               --------                                                        
forth in this Section 3.03 within 30 days of Lenders' demand thereunder shall
entitle the Lenders to all of the rights and remedies available to Lenders under
this Agreement and at law or equity, including, without limitation, the right of
specific performance.

           (d) Financing of Put.  Upon the exercise of the put rights described
               ----------------                                                
in this section, the Company shall pay the Put Price in cash, to the extent the
Company (i) has funds legally available, and (ii) has available cash or short
term investments which may be liquidated.  To the extent the Company is unable
to pay the Put Price in cash, the Company may finance the Put Price in the form
of senior debt, subordinated debt without equity (at an interest rate of 13% per
annum or less) or with a note payable to Allied on commercially reasonable
terms.  The Company shall not be required to finance the Put Price by issuing
additional equity securities.

           (e) Limitation on Exercise of Put.  In no event may the Lenders
               -----------------------------                              
exercise their rights hereunder if doing so would cause the Company to violate
the terms of the Bank Loan Agreement, or any successor document, or any similar
agreement entered into by the Company with a lender of Permitted Senior Debt.

Company's Business, then any personal gain relating to such Transfer of the
Company's Business and flowing to any officer, director or principal shareholder
of the Company otherwise than through direct payment for their equity ownership
in the Company or through dividends or return of capital paid in respect
thereof, shall be added to the direct consideration for the sale in calculating
the total sale price for purposes of determining any share thereof which the
Lenders may be entitled to receive.  Such personal gain shall include without
limitation any salaries or consulting fees in excess of fair market compensation
payable in connection with the Company's operations after such sale or any
points or fees paid to induce such sale.  In the event of any disputes arising
hereunder, the parties shall obtain a fairness opinion from an investment banker
chosen by the parties.  In the event the parties cannot agree on an investment
banker, the Company shall select one investment banker, the Lenders shall select
one investment banker and the two investment bankers shall select a third
investment banker who shall be retained to render the fairness opinion.  The
Company and the Lenders shall equally share the expenses related hereto.

------------                                                                   
been no "reportable events" as set forth in Section 4043(b) of ERISA with
respect to any such plan, and no termination of any such plan since the
effective date of ERISA which could result in any tax, penalty or liability
being imposed upon the Company.  The Company has not participated in, and the
execution and delivery of this Agreement by the Company will not involve, any
"prohibited transaction" (as defined in Section 4975 of the Internal Revenue
Code of 1986, as amended) that could subject the Company to any tax or penalty
imposed by Section 4975 of the Internal Revenue Code of 1986, as amended.  To
the best knowledge of the Company, no predecessor-in-interest to the Company has
participated in any "prohibited transaction" (as defined in Section 4975 of the
Internal Revenue Code of 1986, as amended) that could subject the Company to any
tax or penalty imposed by Section 4975 of the Internal Revenue Code of 


                                    - 20 -

1986, as amended. Since the effective date of ERISA, neither the Company, nor,
to the best knowledge of the Company, any predecessor-in-interest to the
Company, has incurred any "accumulated funding deficiency", as such term is
defined in Section 302 of ERISA, to which the Company could be subject or for
which it might be liable. The Company is not, and immediately after the Closing
will not be, a party to, and none of the operations of the Company is, or after
the Closing will be, covered by, a "multiemployer plan", as defined in Section
3(37) of ERISA.

          4.29  Collective Bargaining.  The Company is not, and after the
                ---------------------                                    
Closing will not be, a party to or subject to any collective bargaining
agreements or union contracts.  There are no labor disputes pending or
threatened against the Company or, to the best knowledge of the Company, between
the Company and its employees which have affected, or so far as the Company can
reasonably foresee may affect, materially and adversely the business or
condition of the Company or the Company's business or prospects.

          4.30  Employees.  Attached hereto as Exhibit 4.30 is an accurate and
                ---------                      ------------                   
complete list of all employment and compensation contracts, including all
retirement benefit agreements not disclosed on Exhibit 4.28, between the Company
                                               ------------                     
and officers and executives of the Company.  The Company has made available to
the Lenders accurate and complete copies of all such contracts.  No officer of
the Company has advised the Company (orally or in writing) that he or she
intends to terminate employment with the Company.

          4.31  Brokers.  Except for a fee payable by the Company as set forth
                -------                                                       
in the engagement letter between the Company and Legg Mason Wood Walker,
Incorporated, the Company has no knowledge of any brokerage fees due for the
transactions contemplated hereby and will indemnify Lenders for any claims with
respect thereto.

          ----------                                                        
certain Security Documents executed and delivered pursuant thereto, this
Debenture is secured by the Collateral.

     5.   Subordination.  The indebtedness represented by this Debenture is
          -------------

          -------------------------                                           
rights under this Debenture nor delegate any of its duties under this Debenture

long as any indebtedness is outstanding hereunder, it will, unless the Holder

rescind the declared default if the Borrower has paid a sum sufficient to pay
all overdue interest and overdue principal amounts, all interest on the overdue
installments of interest and/or principal at the penalty rate, and the Holder's
reasonable costs of enforcing its rights hereunder (including attorneys' fees
and disbursements).

party hereto or any failure or delay on the part of the Holder in exercising any
rights or remedies hereunder shall operate as a waiver of any rights or remedies
of the Holder under this or any other applicable instrument.  No single or
partial exercise of any rights or remedies hereunder shall operate as a waiver
or preclude the exercise of any other rights or remedies hereunder.

     1.   Exercise and Conversion of Warrant.
          ---------------------------------- 

          1.1  Exercise.  Subject to Section 1.3 hereof, this Warrant may be
               --------                                                     
exercised in full or in part at any time or from time to time until the
Expiration Date by the holder hereof either (a) by surrender of this Warrant and
the subscription form annexed hereto (duly executed) by such holder, to the
Company at its principal office, accompanied by payment, in cash, by the
surrender of any promissory note or notes or other instruments evidencing any
indebtedness outstanding from the Company to the holder hereof or by certified
or official bank check payable to the order of the Company in the amount
obtained by multiplying (x) the number of shares of Common Stock designated by
the holder in the subscription form by (y) the Exercise Price then in effect, or
(b) if in connection with a registered public offering of the Company's
securities, the surrender of this Warrant (with the subscription form annexed
hereto duly executed) at the principal office of the Company together with
notice of arrangements reasonably satisfactory to the Company for payment to the
Company either by check or from the proceeds of the sale of shares to be sold by
the holder in such public offering of an amount equal to the then applicable
Exercise Price per share multiplied by the number of shares of Common Stock then
being purchased.  On any partial exercise the Company at its expense will
forthwith issue and deliver to or upon the order of the holder hereof a new
Warrant or Warrants of like tenor, in the name of the holder hereof or as such
holder (upon payment by such holder of any applicable transfer taxes) may
request, providing in the aggregate on the face or faces thereof for the number
of shares of Common Stock for which such Warrant or Warrants may still be
exercised.

          1.2  Conversion.
               ---------- 

               (a) The holder of this Warrant shall have the right to require
the Company to convert this Warrant (the "Conversion Right"), in whole or in
part, at any time prior to the Expiration Date, into shares of Common Stock as
provided for in this Section 1.2. Upon exercise of the Conversion Right, the
Company shall deliver to the holder (without payment by the holder of any
Exercise Price) such number of fully paid and nonassessable shares of Common
Stock as is computed using the following formula:

                                  X = Y (A-B)
                                      --------
                                        A

where X =  the number of shares of Common Stock to be issued to the holder
           hereof pursuant to this Section 1.2.

      Y =  the number of shares of Common Stock then issuable upon the exercise
           of this Warrant that the holder hereof is surrendering in connection
           with the exercise of the Conversion Right.

      A =  the Fair Market Value of one share of Common Stock, at the time the
           Conversion Right is exercised pursuant to this Section 1.2.

                                     - 2 -
<PAGE>
 
      B = the Exercise Price in effect under this Warrant at the time the
          Conversion Right is exercised pursuant to this Section 1.2.

                      (b)  The Conversion Right may be exercised by the holder,
at any time, or from time to time, prior to the Expiration Date, on any business
day by delivering a written notice (the "Conversion Notice") to the Company
exercising the Conversion Right and specifying (i) the total number of shares of
Common Stock the holder wishes to acquire pursuant to such conversion and (ii) a
place and a date not less than one nor more than 20 business days from the date
of the Conversion Notice for the closing of such purchase.

                      (c)  Upon any exercise of the Conversion Right under
Section 1.2(b) hereof, (i) the holder will surrender the Warrant and (ii) the
Company will deliver to the holder a certificate or certificates for the number
of shares of Common Stock issuable upon such conversion, together with cash, in
lieu of any fraction of a share, as provided in Section 2 below. Upon any
partial exercise of such Conversion Right, the Company at its expense will
forthwith issue and deliver to or upon the order of the holder hereof a new
Warrant or Warrants of like tenor, in the name of the holder hereof or as such
holder (upon payment by such holder of any applicable transfer taxes) may
request, providing in the aggregate on the face or faces thereof for the number
of shares of Common Stock for which such Warrant or Warrants may still be
exercised or converted after giving effect to the exercise of the Conversion
Right.

                      (d)  Fair Market Value of a share of Common Stock as of a
particular date (the "Determination Date") shall mean:

                        (i)  If the Company's Common Stock is traded on an
          exchange or is quoted on The Nasdaq National Market, then the average
          of the sale prices reported for the 20 business days immediately
          preceding the Determination Date.

                       (ii)  If the Company's Common Stock is not traded on an
          exchange or on The Nasdaq National Market but is traded in the over-
          the-counter market, then the average of the means of the closing bid
          and asked prices reported for the 20 business days immediately
          preceding the Determination Date.

                      (iii)  Except as provided in subsections 1.2(d)(iv) below,
          if the Company's Common Stock is not publicly traded, then the
          Appraised Fair Market Value, pursuant to Section 1.2(e) below.

                       (iv)  If the Determination Date is the date of a
          liquidation, dissolution or winding up of the Company, or any event
          deemed to be a liquidation, dissolution or winding up pursuant to the
          Company's Certificate of Incorporation, as amended (the "Charter"),
          then the amount specified in the Charter upon liquidation, dissolution
          or winding up, assuming for purposes of this 

                                     - 3 -
<PAGE>
 
          subsection 1.2 that all of the shares of Common Stock issuable upon
          exercise of all of the Warrants are outstanding at the Determination
          Date.

               (e)  Appraised Fair Market Value.  The "Appraised Fair Market
                    ---------------------------                             
Value" shall be determined by the following method:

                    (i)  If the Company and the Holder agree on the selection of
          an appraiser, such appraiser shall determine a value, and such value
          shall be the Appraised Fair Market Value;

                    (ii)  If the Company and the Holder shall not agree on the
          selection of an appraiser within 10 days, each of the Company and the
          Holder, shall select an appraiser who shall each determine a value;

                    (iii)  If the values determined by such two appraisers are
          the same (or the lower value determined by an appraiser is within one
          percent of the value determined by the other), then such value (or the
          average of such two values) shall be the Appraised Fair Market Value;

                    (iv)  If the foregoing two appraisals are not the same and
          the lower value determined by an appraiser differs by more than one
          percent of the value determined by the other, then the appraisers
          shall together select a third appraiser to determine a value;

                    (iv)  If the determination of the third appraiser is greater
          than the largest of the first two appraisals or less than the smallest
          of the first two appraisals, then the average of the first two
          appraisals shall be the Appraised Fair Market Value; and

                    (v)  If the determination of the third appraiser is between
          the first two appraisals, then the average of the third appraisal and
          the closest of the first two appraisals shall be the Appraised Fair
          Market Value.

Each party shall pay the fees and costs of the appraiser it selects, and the
fees and costs of the third appraiser, if any, shall be paid equally by Company
and the Holder.

          1.3  Trustee for Warrant Holders.  In the event that a bank or trust
               ---------------------------                                    
company shall have been appointed as trustee for the holder of the Warrant
pursuant to subsection 4.2 hereof, such bank or trust company shall have all the
powers and duties of a warrant agent appointed pursuant to Section 15 and shall
accept, in its own name for the account of the Company or such successor person
as may be entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise or conversion of this Warrant

notice of the appointment of any trustee and any change thereof.

     2.   Delivery of Stock Certificates.  As soon as practicable after the
          ------------------------------                                   
exercise or conversion of this Warrant, and in any event within 30 days
thereafter, the Company at its expense (including the payment by it of any
applicable issue or stamp taxes) will cause to be issued in the name of and
delivered to the holder hereof, or as such holder (upon payment by such holder
of any applicable transfer taxes) may direct, a certificate or certificates for
the number of fully paid and nonassessable shares of Common Stock to which such
holder shall be entitled on such exercise or conversion, in such denominations
as may be requested by such holder, plus, in lieu of any fractional share to
which such holder would otherwise be entitled, cash equal to such fraction

is entitled upon such exercise or conversion pursuant to Section 1 or otherwise.

Common Stock shall have received, or (on or after the record date fixed for the
determination of shareholders eligible to receive) shall have become entitled to
receive, without payment therefor,

          (a)  other or additional stock or other securities or property (other
than cash) by way of dividend, or

conversion hereof as provided in Section 1, shall be entitled to receive the
amount of stock and other securities and property (including cash in the cases
referred to in subdivisions (b) and (c) of this Section 3) which such holder
would hold on the date of such exercise or conversion if on the date hereof he
had been the holder of record of the number of shares of Common Stock called for
on the face of this Warrant and had thereafter, during the period from the date
hereof to and including the date of such exercise or conversion retained such
shares and all such other or additional stock and other securities and property
(including cash in the cases referred to in subdivisions (b) and (c) of this
Section 3) receivable by him as aforesaid during such period, giving effect to

     4.   Adjustment for Reorganization, Consolidation, Merger, etc.
          ----------------------------------------------------------

from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then in each such
case, the holder of this Warrant, on the exercise or conversion hereof as
provided in Section 1 at any time after the consummation of such reorganization,
consolidation or merger or the effective date of such dissolution, as the case
may be, shall receive, in lieu of the Common Stock issuable on such exercise or
conversion prior to such consummation or such effective date, the stock and
other securities and property (including cash) to which such holder would have
been entitled upon such consummation or in connection with such dissolution, as
the case may be, if such holder had so exercised or converted this Warrant,
immediately prior thereto, all subject to further adjustment thereafter as
provided in Sections 3 and 5.

          4.2  Dissolution.  In the event of any dissolution of the Company
               -----------

merger or transfer followed by dissolution referred to in this Section 4 (where,
in the case of a transfer followed by a dissolution, the transferee is paying
for the Company's assets all or in part with its equity securities), this
Warrant shall continue in full force and effect and the terms hereof shall be
applicable to the shares of stock and other securities and property receivable
on the exercise or conversion of this Warrant after the consummation of such
reorganization, consolidation or merger or the effective date of dissolution
following any such transfer, as the case may be.  The Company shall be
obligated, prior to and as a condition of such transaction, to enter into an
agreement for the benefit of the Warrant holders that is binding upon the issuer
of any such stock or other securities, including, in the case of any such
transfer, the person acquiring all or substantially all of the properties or
assets of the Company, pursuant to which such person shall expressly assume the

Stock, then, in each such event, the Exercise Price shall, simultaneously with
the happening of such event be adjusted by multiplying the then Exercise Price
by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such event and the denominator of which
shall be the number of shares of Common Stock outstanding immediately after such
event, and the product so obtained shall thereafter be the Exercise Price then
in effect. The Exercise Price, as so adjusted, shall be readjusted in the same
manner upon the happening of any successive event or events described herein in
this Section 5. The Holder of this Warrant shall thereafter, on the exercise
hereof as provided in Section 1, be entitled to receive that number of shares of
Common Stock determined by multiplying the number of shares of Common Stock
issuable upon the exercise of this Warrant immediately prior to such issuance by
a fraction of which (i) the numerator is the Exercise Price in effect
immediately prior to the issuance resulting in an adjustment to the Exercise
Price and (ii) the denominator is the Exercise Price in effect after giving
effect to any adjustment resulting from such issuance.

          5.2  Adjustment for Issuances Below Exercise Price.  If the Company
               ---------------------------------------------                 
shall at any time or from time to time after August 30, 1995 issue or sell any
shares of Common Stock (other than (i) shares issued in transactions to which
Section 5.1 of this Warrant applies, (ii) up to 792,450 shares of Common Stock
(appropriately adjusted for subdivisions, combinations, stock dividends and the
like) issued as compensation or pursuant to the exercise of options granted as
compensation to employees, officers, directors or consultants of the Company in
connection with their service to the Company, (iii) shares of Common Stock
issuable upon conversion of the Series A Convertible Preferred Stock, Series C
Convertible Preferred Stock, or Series D Convertible Preferred Stock, (iv)
shares of Common Stock to be issued to shareholders of Educo, Inc. and (v)
shares of Common Stock issuable pursuant to subscriptions, warrants, options,
convertible securities, or other rights outstanding as of August 30, 1995 and
not included in clauses (i), (ii) or (iii) above) for a consideration per share
less than the Exercise Price in effect for this Warrant immediately prior to the
time of such issue or sale, then forthwith upon such issue or sale the Exercise
Price shall (until another such issue or sale) be reduced to a price (calculated
to the nearest cent) determined by dividing (i) an amount equal to the sum of
(X) the number of shares of Common Stock outstanding immediately prior to such
issue or sale, multiplied by the Exercise Price in effect immediately prior to
such event plus (Y) the consideration, if any, received by the Company upon such
issue or sale, by (ii) the total number of shares of Common Stock outstanding
immediately after such issue or sale.  Further, the number of shares purchasable
thereunder shall be increased to a number determined by dividing (i) the number
of shares purchasable hereunder immediately prior to such issue or sale,
multiplied by a fraction of which (x) the numerator is the Exercise Price
hereunder immediately prior to such event, and (y) the denominator is the
Exercise Price in effect immediately after the foregoing adjustment.

          For the purposes of this Section 5.2, the following provisions shall
also be applicable:

                                     - 7 -
<PAGE>
 
          A.   In case the Company shall in any manner offer any rights to
subscribe for or to purchase shares of Common Stock, or grant any options for
the purchase of shares of Common Stock, at a price less than the Exercise Price
in effect immediately prior to the time of the offering of such rights or the
granting of such options, as the case may be, all shares of Common Stock which
the holders of such rights or options shall be entitled to subscribe for or
purchase pursuant to such rights or options shall be deemed to be issued or sold
as of the date of the offering of such rights or the granting of such options,
as the case may be, and the minimum aggregate consideration named in such rights
or options for the Common Stock covered thereby, plus the consideration received
by the Company for such rights or options, shall be deemed to be the
consideration actually received by the Company (as of the date of the offering
of such rights or the granting of such options, as the case may be) for the
issue or sale of such shares.

          B.   In case the Company shall in any manner issue or sell any shares
of any class or obligations directly or indirectly convertible into or
exchangeable for shares of Common Stock and the price per share for which Common
Stock is deliverable upon such conversion or exchange (determined by dividing
(i) the total minimum amount received or receivable by the Company in
consideration of the issue or sale of such convertible or exchangeable shares or
obligations, plus the total minimum amount of premiums, if any, payable to the
Company upon conversion or exchange, by (ii) the total number of shares of
Common Stock necessary to effect the conversion or exchange of all such
convertible or exchangeable shares of obligations) shall be less than the
Exercise Price in effect immediately prior to the time of such issue or sale,
then such issue or sale shall be deemed to be an issue or sale (as of the date
of issue or sale of such convertible or exchangeable shares or obligations) of
the total maximum number of shares of Common Stock necessary to effect the
conversion or exchange of all such convertible or exchangeable shares or
obligations, and the total minimum amount received or receivable by the Company
in consideration of the issue or sale of such convertible or exchangeable shares
or obligations, plus the total minimum amount of premiums, if any, payable to
the Company upon exchange or conversion, shall be deemed to be the consideration
actually received (as of the date of the issue or sale of such convertible or
obligations) for the issue or sale of Common Stock.

          C.   In determining the amount of consideration received by the
Company for Common Stock, securities convertible thereinto or exchangeable
therefor, or rights or options for the purchase thereof, expenses or
underwriting discounts or commissions paid by the Company shall be excluded.
The Board shall determine in good faith the fair value of the amount of
consideration other than money received by the Company upon the issue by it of
any of its securities.  The Board shall also determine in good faith the fair
value of any dividend or other distribution made upon Common Stock payable in
property, securities of the Company other than Common Stock or securities of a
corporation other than the Company.  The Board shall, in case any Common Stock,
securities convertible thereinto or exchangeable therefor, or rights or options
for the purchase thereof are issued with other stock, securities or assets of
the Company, determine in good faith what part of the consideration received
therefor is applicable to the issue of the Common Stock, securities convertible
thereinto or exchangeable therefor, or rights or options for the purchase
thereof.

                                     - 8 -
<PAGE>
 
          D.   If there shall be any change in (i) the minimum aggregate
consideration named in the rights or options referred to in Subsection A above,
(ii) the consideration received by the Company for such rights or option, (iii)
the price per share for which Common Stock is deliverable upon the conversion or
exchange of the convertible or exchangeable shares or obligations referred to in
Subsection B above, (iv) the number of shares which may be subscribed for or
purchased pursuant to the rights or options referred to in Subsection A above,
or (v) the rate at which the convertible or exchangeable shares or obligations
referred to in Subsection B above are convertible into or exchangeable for
Common Stock, then the Exercise Price in effect at the time of such event shall
be readjusted to the Exercise Price which would have been in effect at such time
had such rights, options, or convertible or exchangeable shares or obligations
still outstanding provided for such changed consideration, price per share,
number of shares, or rate of conversion or exchange, as the case may be, at the
time initially offered, granted, issued or sold.

          E.   Upon the expiration of the right to convert or exchange any
convertible securities, or upon the expiration of any rights, options or
warrants, without conversion, exchange or exercise, the issuance of which
convertible securities, rights, options or warrants effected an adjustment in
the Exercise Price, the Exercise Price shall forthwith be readjusted and
thereafter be the price which it would have been (but reflecting any other
adjustments in the Exercise Price made pursuant to the terms hereof after the
issuance of such convertible securities, rights, options or warrants) had the
adjustment of the Exercise Price made upon the issuance or sale of such
convertible securities or issuance of rights, options or warrants been made on
the basis of the issuance only of the number of additional shares of Common
Stock actually issued upon conversion or exchange of such convertible
securities, or upon the exercise of such rights, options or warrants, and
thereupon only the number of additional shares of Common Stock actually so
issued, if any, shall be deemed to have been issued and only the consideration
actually received by the Company (computed as set forth herein) shall be deemed
to have been received by the Company.

          5.3  Adjustment for Monetary Defaults.  If the Company shall be in
               --------------------------------                             
default under the payment terms of the Debentures as defined in the Investment
Agreement for a continuous period of 270 days, the Exercise Price shall
immediately thereafter be reduced to the lesser of $1.00 per share or the Fair
Market Value of a share of Common Stock on the last day of such 270 day period,
as determined pursuant to Section 1.2(d).

     6.   No Impairment.  The Company will not, by amendment of its charter or
          -------------                                                       
through any reorganization, transfer of assets, consolidation, merger,
dissolution, or any other similar voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the holder of the Warrant against impairment due to such event.
Without limiting the generality of the foregoing, the Company (a) will not
increase the par value of any shares of stock receivable

                                     - 9 -
<PAGE>
 
on the exercise or conversion of the Warrant above the amount payable therefor
on such exercise or conversion, (b) will take all action that may be necessary
or appropriate in order that the Company may validly and legally issue fully
paid and nonassessable shares of stock, free from all taxes, liens and charges
with respect to the issue thereof, on the exercise or conversion of all or any
portion of this Warrant from time to time outstanding, and (c) will not
consolidate with or merge into any other person or permit any such person to
consolidate with or merge into the Company (if the Company is not the surviving
person) or transfer all or substantially all the assets of the Company to
another person, unless such other person shall expressly assume in writing and
will be bound by all the terms of this Warrant, including the provisions of
Section 4.

     7.   Certificate as to Adjustments.  In each case of any adjustment or
          -----------------------------                                    
readjustment in the number or type of shares or securities issuable on the
exercise or conversion of this Warrant, an officer of the Company will promptly
compute such adjustment or readjustment in accordance with the terms of this
Warrant and prepare a certificate setting forth such adjustment or readjustment,
the Exercise Price resulting therefrom and the increase or decrease, if any, or
the number of shares purchasable at such price upon exercise or conversion of
the Warrant, and showing in detail the facts and computation upon which such
adjustment or readjustment is based.  The Company will forthwith mail a copy of
each such certificate to each registered holder of this Warrant, and will, on
the written request at any time of the holder of this Warrant, furnish to such
holder a like certificate setting forth the Exercise Price at the time in effect
and showing how such Exercise Price was calculated.

     8.   Notices of Record Date, Etc.  In the event of
          ---------------------------                  

          (a)  any taking by the Company of a record of the holders of any class
of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend on, or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, or
 
          (b)  any capital reorganization of the Company, any reclassification
or recapitalization of the capital stock of the Company or any transfer of all
or substantially all the assets of the Company to or consolidation or merger of
the Company with or into any other person, or

          (c)  any voluntary or involuntary dissolution, liquidation or winding-
up of the Company,

then and in each such event the Company will mail or cause to be mailed to the
registered holder of this Warrant a notice specifying (i) the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock 

                                     - 10 -
<PAGE>
 
shall be entitled to exchange their shares of Common Stock for securities or
other property deliverable on such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up, and (iii) the amount and character of any stock or other securities,
or rights or option with respect thereto, proposed to be issued or granted, the
date of such proposed issue or grant and the persons or class of persons to whom
such proposed issue or grant is to be offered or made. Such notice shall also
state that the action in question or the record date is subject to the
effectiveness of a registration statement under the Securities Act of 1933, as
amended (the "Securities Act"), or a favorable vote of stockholders if either is
required. Such notice shall be mailed at least 20 days prior to the date
specified in such notice on which any such action is to be taken or the record
date, whichever is earlier.

     9.   Reservation of Stock, etc., Issuable on Exercise of Warrants.  The
          ------------------------------------------------------------      
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise or conversion of the Warrant, all shares of Common
Stock from time to time issuable on the exercise or conversion of this Warrant.

     10.  Registration.  If the issuance of any shares of Common Stock required
          ------------                                                         
to be reserved for purposes of exercise or conversion of this Warrant or for the
conversion of such shares requires registration with, or approval of, any
Federal governmental authority under any Federal or state law (other than any
registration under the Securities Act) or listing on any national securities
exchange, before such shares may be issued upon exercise or conversion of this
Warrant or such conversion, the Company will, at its expense, use its best
efforts to cause such shares to be duly registered or approved, or listed on the
relevant national securities exchange, as the case may be, at such time, so that
such shares may be issued in accordance with the terms hereof and so converted.

     11.  Transfer of Warrant.  The transfer of this Warrant and all rights
          -------------------

Warrant, on delivery of an indemnity agreement or security reasonably

mutilation, on surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor;
                                                                               
provided, however, if this Warrant of which the original holder of this Warrant,
--------  -------

Warrant in replacement of such lost, stolen or destroyed Warrant other than the
registered holder's written agreement to indemnify the Company.

     15.  Warrant Agent.  The Company may, by written notice to the registered
          ------- -----                                                        
holder of this Warrant, appoint an agent for the purpose of issuing Common Stock
on the exercise or conversion of the Warrant pursuant to Section 1, exchanging

     16.  Remedies.  The Company stipulates that the remedies at law of the
          --------                                                        
holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that such terms may be
specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms
hereof or otherwise.

     17.  Closing of Books.  The Company will at no time close its transfer
          ----------------                                                 
books against the transfer of any Warrant or of any shares of Common Stock
issued or issuable upon 

                                     - 12 -
<PAGE>
 
the exercise or conversion of any Warrant in any manner which interferes with
the timely exercise or conversion of this Warrant.

     18.  No Rights or Liabilities as a Stockholder.  This Warrant shall not
          -----------------------------------------                         
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Common Stock, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a stockholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

     19.  Notice, etc.  All notices and other communications from the Company to
          -----------                                                           
the registered holder of this Warrant shall be mailed by first class registered
or certified mail, postage prepaid, at such address as shall have been furnished
to the Company in writing by such holder.

     20.  Investment Representations.  The holder hereof (and each subsequent
          --------------------------                                         
holder) represents to the Company that this Warrant is being acquired for the
holder's own account and for the purpose of investment and not with a view to,
or for sale in connection with, the distribution thereof, nor with any present
intention of distributing or selling the Warrant or the Common Stock issuable
upon exercise or conversion of the Warrant.  The holder hereof acknowledges and
agrees that the Warrant and the Common Stock issuable upon exercise or
conversion of the Warrant (if any) have not been (and at the time of acquisition
by such holder, will not have been or will not be) registered under the
Securities Act or under the securities laws of any state, in reliance upon
certain exemptive provisions of such statutes.  The holder hereof recognizes and
acknowledges that because the Warrant and the Common Stock issuable upon
exercise or conversion of the Warrant (if any) are unregistered, they are not
presently eligible for resale, and may only be resold in the future pursuant to
an effective registration statement under the Securities Act and any applicable
state securities laws, or pursuant to a valid exemption from such registration
requirements.  Each subsequent holder hereof shall be required to make all of
the representations which are required by this Section 20 to be made by the
initial holder hereof, including without limitation the representations which
are contained in the Agreement.  The Company shall not be required to register
the transfer of the Warrant or any Common Stock into which the Warrant may be
converted on the books of the Company unless the Company shall have been
provided at the transferor's expense with an opinion of counsel reasonably
satisfactory to the Company prior to such transfer to the effect that
registration under the Securities Act of 1933, as amended, or any applicable
state securities laws is not required in connection with the transaction
resulting in such transfer.  The Warrant shall bear the restrictive legend set
forth at the beginning of this Warrant, and any share certificate issued upon
conversion shall bear a comparable legend, except that such restrictive legend
shall not be required if the opinion of counsel reasonably satisfactory to the
Company referred to above is to the further effect that such legend is not
required in order to establish compliance with the provisions of the Securities
Act of 1933, as amended, and any applicable state securities laws, or if the
transfer is made in accordance with the provisions of Rule 144 under such act.

     21.  Binding Effect on Successors.  This Warrant shall be binding upon any
          ----------------------------                                         
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets (to the extent provided in
Section 4), and all of the obligations of the Company relating to the Common
Stock issuable upon the exercise or conversion of this Warrant shall survive the
exercise, conversion, and termination of this Warrant and all of the covenants
and agreements of the Company shall inure to the benefit of the successors and
assigns of the holder hereof.  The Company will, at the time of the exercise or
conversion of this Warrant, in whole or in part, upon request of the holder
hereof but at the Company's expense, acknowledge in writing its continuing
obligation to the holder hereof in respect of any rights (including, without
limitation, any right to registration of the shares of Registrable Securities)
to which the holder hereof shall continue to be entitled after such exercise or
conversion in accordance with this Warrant; provided, that the failure of the
                                            --------                         
holder hereof to make any such request shall not affect the continuing
obligation of the company to the holder hereof in respect of such rights.

     22.  Miscellaneous.  This Warrant and any term hereof may be changed,
          -------------                                                  
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought, subject to the provisions of the Agreement.  This Warrant shall be
construed and enforced in accordance with and governed by the internal laws of
the State of Delaware.  The headings in this Warrant are for purposes of
reference only, and shall not limit or otherwise affect any of the terms hereof.
This Warrant is being executed as an instrument under seal.  The invalidity or
unenforceability of any provision hereof shall in no way affect the validity or
enforceability of any other provision.

or any similar federal statute, and the rules and regulations of the Commission

     "Restricted Stock" shall mean the Conversion Shares and Warrant Shares,

          ------------------                                                  
Conversion Shares or Warrant Shares and each Warrant shall, except as otherwise
provided in this Section 2 or in Section 3, be stamped or otherwise imprinted
with a legend substantially in the following form:

     "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND
     MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN
     REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE."

A certificate or Warrant shall not bear such legend if in the written opinion of

     3.   Notice of Proposed Transfer.  Prior to any proposed transfer of any

Preferred Shares, Conversion Shares, Warrants or Warrant Shares (other than
under the circumstances described in Sections 4, 5 or 6), the holder thereof
shall give written notice to the Company of its intention to effect such
transfer.  Each such notice shall describe the manner of the proposed transfer
and, if requested by the Company, shall be accompanied by an opinion of counsel
satisfactory to the Company (it being agreed that Piper & Marbury, L.L.P. shall
be satisfactory) to the effect that the proposed transfer may be effected
without registration under the Securities Act, whereupon the holder thereof
shall be entitled to transfer such stock or Warrant in accordance with the terms
of its notice.  Each certificate for Preferred Shares, Conversion Shares or
Warrant Shares and each Warrant transferred as above provided shall bear the
legend set forth in Section 2, except that such certificate or Warrant shall not
bear such legend if the opinion of counsel referred to above is to the effect
that the transferee and any subsequent transferee would be entitled to transfer
such securities in a public sale without registration under the Securities Act.
The restrictions provided for in this Section 3 shall not apply to securities
which are not 

                                     - 2 -
<PAGE>
 
required to bear the legend prescribed by Section 2 in accordance with the
provisions of that Section.

     4.   Required Registration.  (a)  Subject to the limitation expressed in
          ---------------------                                              
Section 5(b), at any time after the date of this Agreement that the Company is
ineligible to use a Form S-3 to effect the registrations contemplated by Section
6 below, the holders of Restricted Stock constituting at least 50% of the total
shares of Restricted Stock then outstanding may request the Company to register
under the Securities Act all or any portion of the shares of Restricted Stock
held by such requesting holder or holders for sale in the manner specified in
such notice, provided that the shares of Restricted Stock for which registration
             --------                                                           
has been requested shall constitute at least 50% of the total shares of
Restricted Stock originally issued if such holder or holders shall request the
registration of less than all shares of Restricted Stock then held by such
holder or holders.  For purposes of this Section 4 and Sections 5, 6, 13(a) and
13(d), the term "Restricted Stock," shall be deemed to include the number of
shares of Restricted Stock which would be issuable to a holder of Preferred
Shares upon conversion of all Preferred Shares held by such holder at such time
and the number of shares of Restricted Stock which would be issuable to a holder
of Warrants upon exercise of all Warrants held by such holder at such time,
                                                                           
provided, however, that the only securities which the Company shall be required
--------  -------                                                              
to register pursuant hereto shall be shares of Common Stock, and provided,
                                                                 -------- 
further, however, that, in any underwritten public offering contemplated by this
-------  -------                                                                
Section 4 or Sections 5 and 6, the holders of Preferred Shares shall be entitled
to sell such Preferred Shares to the underwriters for conversion and sale of the
shares of Common Stock issued upon conversion thereof.  Notwithstanding anything
to the contrary contained herein, no request may be made under this Section 4 or
under Section 6 within 120 days after the effective date of a registration
statement filed by the Company covering a firm commitment underwritten public
offering in which the holders of Restricted Stock shall have been entitled to
join pursuant to Sections 5 or 6 and in which there shall have been effectively
registered all shares of Restricted Stock as to which registration shall have
been requested.

     (b) Following receipt of any notice under this Section 4, the Company shall
immediately notify all holders of Restricted Stock from whom notice has not been
received and shall use its best efforts to register under the Securities Act,
for public sale in accordance with the method of disposition specified in such
notice from requesting holders, the number of shares of Restricted Stock
specified in such notice (and in all notices received by the Company from other
holders within 30 days after the giving of such notice by the Company).  If such
method of disposition shall be an underwritten public offering, the holders of a
majority of the shares of Restricted Stock to be sold in such offering may
designate the managing underwriter of such offering, subject to the approval of
the Company, which approval shall not be unreasonably withheld or delayed.  The
Company shall be obligated to register Restricted Stock pursuant to this Section
4 and pursuant to Section 6 on a total (for both sections) of two occasions
only, provided, however, that such obligation shall be deemed satisfied only
      --------  -------                                                     
when a registration statement covering all shares of Restricted Stock specified
in notices received as aforesaid, for sale in accordance with the method of
disposition specified by the requesting holders, shall have 

                                     - 3 -
<PAGE>
 
become effective and, if such method of disposition is a firm commitment
underwritten public offering, 75% of all such shares shall have been sold
pursuant thereto.

     (c) The Company may not include in any registration statement referred to
in this Section 4 any shares of Common Stock to be sold for the account of any
person not entitled as of August 30, 1995 to registration rights with respect to
such shares.  The Company may include in any registration statement referred to
in this Section 4 shares of Common Stock to be sold for its own account or for
the account of any other holders of Common Stock who as of August 30, 1995 are
entitled to "piggyback" or "incidental" rights to be included in the
registration statement, in which case such registration statement shall be
deemed to be a registration statement initiated by the Company and shall be
governed by the provisions of Section 5 below.  Except for registration
statements on Form S-4, S-8 or any successor thereto, registration statements
registering securities to be issued by the Company to the seller or sellers in
connection with an acquisition by the Company and registration statements
required to be filed for holders of Common Stock who as of August 30, 1995 are
entitled to "demand" registration rights, the Company will not file with the
Commission any other registration statement with respect to its Common Stock,
whether for its own account or that of other stockholders, from the date of
receipt of a notice from requesting holders pursuant to this Section 4 until the
completion of the period of distribution of the registration contemplated
thereby, as described in Section 7.

     5.  Incidental Registration.
         ----------------------- 

     (a) If the Company at any time (other than pursuant to Section 4 or Section
6) proposes to register any of its securities under the Securities Act for sale
to the public, whether for its own account or for the account of other security
holders or both (except with respect to registration statements on Forms S-4, S-
8 or another form not available for registering the Restricted Stock for sale to
the public, and the registration statement to be filed by the Company to
register the shares of Common Stock to be issued to the stockholders of Educo,
Inc.), each such time it will give written notice to all holders of outstanding
Restricted Stock of its intention so to do.  Upon the written request of any
such holder, received by the Company within 30 days after the giving of any such
notice by the Company, to register any of its Restricted Stock (which request
shall. state the intended method of disposition thereof), the Company will use
its best efforts to cause the Restricted Stock as to which registration shall
have been so requested to be included in the securities to be covered by the
registration statement proposed to be filed by the Company, all to the extent
requisite to permit the sale or other disposition by the holder (in accordance
with its written request) of such Restricted Stock so registered.  In the event
that any registration pursuant to this Section 5 shall be, in whole or in part,
an underwritten public offering of Common Stock, the number of shares of
Restricted Stock to be included in such an underwriting may be reduced (pro rata
among the requesting holders based upon the number of shares of Restricted Stock
owned by such holders) if and to the extent that the managing underwriter shall
be of the opinion that such inclusion would adversely affect the marketing of
the securities to be sold by the Company therein, provided, however, that such
                                                  --------  -------           
number of shares of Restricted Stock shall not be reduced if any shares are to
be included in such underwriting for 

                                     - 4 -
<PAGE>
 
the account of any person other than (i) the Company, (ii) requesting holders of
Restricted Stock or (iii) any other holders of Common Stock who as of August 30,
1995 are entitled to contractual "piggyback" or "incidental" rights to be
included in the registration statement. Whenever a registration statement is
deemed (pursuant to the provisions of Section 4 or Section 6) to be a
registration statement initiated by the Company and therefore governed by the
provisions of this Section 5, such registration statement shall nevertheless be
deemed to count as one of the two registration statements required to be filed
by the Company under Section 6 and Section 4 if the registration statement
covers all shares of Restricted Stock specified in the notices from the
requesting holders thereof for sale in accordance with the method of disposition
specified in such notice, becomes effective and, if such method of disposition
is a firm commitment underwritten public offering, 75% of all such shares are
sold pursuant thereto.

     (b)  Notwithstanding anything herein to the contrary, the Company shall not
be required to file any registration statement registering the Restricted Stock
upon the demand of the holders of the Restricted Stock made under Section 4 or
Section 6 of this Agreement during the period beginning on the date of the
Company's receipt of a notice from requesting holders pursuant to Section 4 or
Section 6 of the Registration Rights Agreement by and among the Company, Edison
Venture Fund II, L.P. and Edison Venture Fund, II-Pa., L.P. and ending on the
date on which the distribution of the securities included in such registration
has been completed.

     6.   Registration on Form S-3.  Subject to the limitation set forth in
          ------------------------                                         
Section 5(b) and in the last sentence of Section 4(a), if at any time (i) a
holder or holders of Restricted Stock constituting at least 50% of the total
shares of Restricted Stock then outstanding request the Company to register
under the Securities Act all or any portion of the shares of Restricted Stock
held by such requesting holder or holders for sale in the manner specified in
such notice (provided that the shares of Restricted Stock for which registration
            ---------                                                           
has been requested shall constitute at least 50% of the total shares of
Restricted Stock originally issued if such holder or holders shall request the
registration of less than all shares of Restricted Stock then held by such
holder or holders) on Form S-3 or any successor thereto for a public offering of
shares of Restricted Stock held by such requesting holder or holders and (ii)
the Company is a registrant entitled to use Form S-3 or any successor thereto to
register such shares, then the Company shall use its best efforts to register
under the Securities Act on Form S-3 or any successor thereto, for public sale
in accordance with the method of disposition specified in such notice, the
number of shares of Restricted Stock specified in such request.  Whenever the
Company is required by this Section 6 to use its best efforts to effect the
registration of Restricted Stock, each of the procedures and requirements of
section 4 (including but not limited to the requirement that the Company notify
all holders of Restricted Stock from whom notice has not been received and
provide them with the opportunity to participate in the offering) shall apply to
such registration, provided, however, that the requirements contained in the
first sentence of Section 4(a) shall not apply to any registration on Form S-3
which may be requested and obtained under this Section 6. The Company may not
include in any 

                                     - 5 -
<PAGE>
 
registration statement referred to in this Section 6 any shares of Common Stock
to be sold for the account of any person not entitled as of August 30 1995 to
registration rights with respect to such shares. The Company may include in any
registration statement referred to in this Section 6 shares of Common Stock to
be sold for its own account or for the account of any other holders of Common
Stock who as of August 30, 1995 are entitled to "piggyback" or "incidental"
rights to be included in the registration statement, in which case such
registration statement shall be deemed to be a registration-statement initiated
by the Company and shall be governed by the provisions of Section 5 above.
Except for registration statements on Form S-4, S-8 or any successor thereto,
registration statements registering securities to be issued by the Company to
the seller or sellers in connection with an acquisition by the Company and
registration statements required to be filed for holders of Common Stock who as
of August 30, 1995 are entitled to "demand" registration rights, the Company
will not file with the Commission any other registration statement with respect
to its Common Stock, whether for its own account or that of other stockholders,
from the date of receipt of a notice from requesting holders pursuant to this
Section 6 until the completion of the period of distribution of the registration
contemplated thereby, as described in Section 7.

     7.   Registration Procedures.  If and whenever the Company is required by
          -----------------------                                             
the provisions of Sections 4, 5 or 6 to use its best efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

     (a)  prepare and file with the Commission a registration statement (which,
in the case of an underwritten public offering pursuant to Section 4, shall be
on Form S-1 or other form of general applicability satisfactory to the managing
underwriter selected as therein provided) with respect to such securities and
use its best efforts to cause such registration statement to become and remain
effective for the period of the distribution contemplated thereby (determined as
hereinafter provided);

     (b)  prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective for the period
specified in paragraph (a) above and comply with the provisions of the
Securities Act with respect to the disposition of all Restricted Stock covered
by such registration statement in accordance with the sellers' intended method
of disposition set forth in such registration statement for such period;

     (c)  furnish to each seller of Restricted Stock and to each underwriter
each number of copies of the registration statement and the prospectus included
therein (including each preliminary prospectus) as such persons reasonably may
request in order to facilitate the public sale or other disposition of the
Restricted Stock covered by such registration statement;

     (d)  use its best efforts to register or qualify the Restricted Stock
covered by such registration statement under the securities or "blue sky" laws
of such jurisdictions as the sellers of Restricted Stock or, in the case of an
underwritten public offering, the managing underwriter reasonably shall request,
provided, however, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;

                                  - 6 -     
<PAGE>
 
     (e)  use its best efforts to list the Restricted Stock covered by such
registration statement with any securities exchange on which the Common Stock of
the Company is then listed;

     (f)  immediately notify each seller of Restricted Stock and each
underwriter under such registration statement, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event of which the Company has knowledge as a result of which
the prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, whereupon each such
seller shall refrain from making any sales of Restricted Stock until a
prospectus supplement describing such event has been forwarded to such seller by
the Company;

     (g)  if the offering is underwritten and at the request of any seller of
Restricted Stock, use its best efforts to furnish on the date that Restricted
Stock is delivered to the underwriters for sale pursuant to such registration:
(i) an opinion dated such date of counsel representing the Company for the
purposes of such registration, addressed to the underwriters and to such seller,
stating that such registration statement has become effective under the
Securities Act and that (A) to the best knowledge of such counsel, no stop order
suspending the effectiveness thereof has been issued and no proceedings for that
purpose have been instituted or are pending or contemplated under the Securities
Act, (B) the registration statement, the related prospectus and each amendment
or supplement thereof comply as to form in all material respects with the
requirements of the Securities Act (except that such counsel need not express
any opinion as to financial statements contained therein) and (C) to such other
effects as reasonably may be requested by counsel for the underwriters or by
such seller or its counsel and (ii) a letter dated such date from the
independent public accountants retained by the Company, addressed to the
underwriters and to such seller, stating that they are independent public
accountants within the meaning of the Securities Act and that, in the opinion of
such accountants, the financial statements of the Company included in the
registration statement or the prospectus, or any amendment or supplement
thereof, comply as to form in all material respects with the applicable
accounting requirements of the Securities Act, and such letter shall
additionally cover such other financial matters (including information as to the
period ending no more than five business days prior to the date of such letter)
with respect to such registration as such underwriters reasonably may request;
and

     (h)  make available for inspection by each seller of Restricted Stock, any
underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such seller
or underwriter, all financial and other records, pertinent corporate documents
and properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such seller,
underwriter, attorney, accountant or agent in connection with such registration
statement.

                                     - 7 -
<PAGE>
 
     For purposes of Section 7(a) and 7(b) and of Section 4(c), the period of
distribution of Restricted Stock in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all securities purchased by it, and the period of distribution
of Restricted Stock in any other registration shall be deemed to extend until
the earlier of the sale of all Restricted stock covered thereby and 120 days
after the effective date thereof.

     In connection with each registration hereunder, the sellers of Restricted
Stock will furnish to the Company in writing such information with respect to
themselves and the proposed distribution by them as reasonably shall be
necessary in order to assure compliance with federal and applicable state
securities laws.

     In connection with each registration pursuant to Sections 4, 5 or 6
covering an underwritten public offering, the Company and each seller agree to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

     8.   Expenses.  All expenses incurred by the Company in complying with
          --------                                                        
Sections 4, 5 and 6, including, without limitation, all registration and filing

incurred in connection with complying with state securities or "blue sky" laws,
fees of the National Association of Securities Dealers, Inc., transfer taxes,
fees of transfer agents and registrars, and costs of insurance for the sellers
of Restricted Stock, but excluding any Selling Expenses, are called

     The Company will pay all Registration Expenses in connection with each
registration statement under Sections 4, 5 or 6.  All Selling Expenses in
connection with each registration statement under Sections 4, 5 or 6 shall be
borne by the participating sellers in proportion to the number of shares sold by
each, or by such participating sellers other than the Company (except to the
extent the Company shall be a seller) as they may agree.

     9.   Indemnification and Contribution.  (a) In the event of a registration
          --------------------------------                                     
of any of the Restricted Stock under the Securities Act pursuant to Sections 4,
5 or 6, the Company will indemnify and hold harmless each seller of such
Restricted Stock thereunder, each underwriter of such Restricted Stock
thereunder and each other person, if any, who controls such seller or
underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such seller,
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or 

                                     - 8 -
<PAGE>
 
alleged untrue statement of any material fact contained in any registration
statement under which such Restricted Stock was registered under the Securities
Act pursuant to Sections 4, 5 or 6, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each such seller, each such
underwriter and each such controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action, provided, however, that the
Company will not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by any such seller, any such underwriter
or any such controlling person in writing specifically for use in such
registration statement or prospectus.

     (b)  In the event of a registration of any of the Restricted Stock under
the Securities Act pursuant to Sections 4, 5 or 6, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Sections 4, 5 or 6, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon, the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company and each such officer, director, underwriter and controlling person
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action,
provided, however, that such seller will be liable hereunder in any such case if
and only to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission made in reliance upon and in conformity with information
pertaining to such seller, as such, furnished in writing to the Company by such
seller specifically for use in such registration statement or prospectus, and
provided, further, however, that the liability of each seller hereunder shall be
limited to the proportion of any such loss, claim, damage, liability or expense
which is equal to the proportion that the public offering price of the shares
sold by such seller under such registration statement bears to the total public
offering price of all securities sold thereunder, but not in any event to exceed
the proceeds received by such seller from the sale of Restricted Stock covered
by such registration statement.

                                     - 9 -
<PAGE>
 
     (c)  Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party other than under this Section 9 and shall only relieve it
from any liability which it may have to such indemnified party under this
Section 9 if and to the extent the indemnifying party is prejudiced by such
omission.  In case any such action shall be brought against any indemnified
party and it shall notify the indemnifying party of the commencement thereof,
the indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 9 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected, provided,
however, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying party, the indemnified party shall have the
right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

     (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Restricted Stock exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 9 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 9 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling holder or any such controlling
person in circumstances for which indemnification is provided under this Section
9; then, and in each such case, the Company and such holder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Restricted Stock offered by the registration statement
bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the public offering price of all
such Restricted Stock offered by it pursuant to such registration statement; and
(B) no person or entity guilty of fraudulent misrepresentation (within the
meaning 

                                    - 10 -
<PAGE>
 
of Section 11(f) of the Securities Act) will be entitled to contribution
from any person or entity who was not guilty of such fraudulent
misrepresentation.

     10.  Changes in Common Stock or Preferred Shares.  If, and as often as,
          -------------------------------------------                       
there is any change in the Common Stock or the Preferred Shares by way of a
stock split, stock dividend, combination or reclassification, or through a
merger, consolidation, reorganization or recapitalization, or by any other
means, appropriate adjustment shall be made in the provisions hereof so that the
rights and privileges granted hereby shall continue with respect to the Common
Stock or the Preferred Shares as so changed.

     11.  Rule 144 Reporting.  With a view to making available the benefits of
          ------------------                                                  
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, the Company
agrees to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

     (b)  use its best efforts to file with the Commission in a timely manner
all reports and other documents required of the Company under the Securities Act
and the Exchange Act; and

     (c)  furnish to each holder of Restricted Stock forthwith upon request a
written statement by the Company as to its compliance with the reporting
requirements of such Rule 144 and of the Securities Act and the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed by the Company as such holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any Restricted Stock without
registration.

     12.  Representations and Warranties of the Company.  The Company represents
          ---------------------------------------------

or other instrument or result in the creation or imposition of any lien, charge
or encumbrance of any nature whatsoever upon any of the properties or assets of

the Company, should not be disclosed, and no sales of Restricted Stock shall be

                         NOBEL EDUCATION DYNAMICS, INC.

          Nobel Education Dynamics, Inc., a corporation organized and existing
under the General Corporation Law of the State of Delaware (the "Corporation"),
DOES HEREBY CERTIFY:

     A.  That, pursuant to authority conferred upon the Board of Directors
by the Certificate of Incorporation of the Corporation (the "Certificate of
Incorporation"), and pursuant to the provisions of Section 151 of Title 8 of the
Delaware Code of 1953, said Board of Directors, at a duly convened meeting of
the Board held on August 22, 1995, adopted a resolution providing for the
designations, preferences and relative, participating, optional and other
special rights, and the qualifications, limitations and restrictions of the
Series D Convertible Preferred Stock, which resolution is as follows:
 
          WHEREAS, the Certificate of Incorporation of this Corporation provides
     for two classes of shares known as Common Stock and Preferred Stock; and

          WHEREAS, the Board of Directors of this Corporation is authorized by
     the Certificate of Incorporation to provide for the issuance of the shares
     of Preferred Stock in series, and by filing a certificate pursuant to the
     applicable law of the State of Delaware, to establish from time to time the
     number of shares to be included in each such series, and to fix the
     designation, preferences and rights of the shares of each such series and
     the qualifications, limitations and restrictions thereof.

          NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors deems it
     advisable to, and hereby does, designate a Series D Convertible Preferred
     Stock and fixes and determines the preferences, rights, qualifications,
     limitations and restrictions relating to the Series D Convertible Preferred
     Stock as follows:
 
          1.   Designation.  The shares of such series of Preferred Stock shall
               -----------                                                     
be designated as "Series D Convertible Preferred Stock" (referred to herein as
the "Series D Convertible Preferred Stock").

          2.   Authorized Number.  The number of shares constituting Series D
               -----------------                                             
Convertible Preferred Stock shall be 1,063,830.

          3.   Dividends.  Holders of shares of Series D Convertible Preferred
               ---------                                                      
Stock shall not be entitled to dividends, except as provided below.  If a
dividend on the Common Stock is declared by the Board of Directors, the Board of
Directors shall simultaneously declare a dividend on the Series D Convertible
Preferred Stock in an amount per share equal

                                     - 1 -
<PAGE>
 
to (a) the product of (i) the dividend per share of Common Stock, multiplied by
(ii) the number of shares of Common Stock into which all of the outstanding
Series D Convertible Preferred Stock could then be converted, divided by (b) the
number of Series D Convertible Preferred Stock then outstanding, and rounded to
the nearest cent, each such determination to be made as of the record date for
the determination of the dividend.  The term "dividend," when used in this
Section 3, shall refer to any dividend which is not as stock dividend described
in Section 8(d) hereof.

          4.   Liquidation.  Upon any liquidation, dissolution or winding up of
               -----------                                                     
the Corporation, whether voluntary or involuntary, the holders of the shares of
Series D Convertible Preferred Stock shall be entitled, before any distribution
or payment is made upon any Common Stock or any other class or series of stock
ranking junior to the Series D Convertible Preferred Stock as to distribution of
assets upon liquidation, to be paid an amount equal to $1.88 per share plus an
amount equal to all unpaid dividends, without interest, which have been declared
on such outstanding shares of Series D Convertible Preferred Stock prior to the
date of the liquidation payment, such amounts being sometimes referred to as the
"Liquidation Payments", and the holders of Series D Convertible Preferred Stock
shall not be entitled to any further payment.  If upon such liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed among the holders of Series D Convertible Preferred
Stock of the Corporation and any other class or series of stock ranking equal to
the Series D Convertible Preferred Stock as to distribution of assets upon
liquidation shall be insufficient to permit payment to the holders of Series D
Convertible Preferred Stock of the entire amount of the Liquidation Payment,
then the entire assets of the Corporation available for distribution to the
stockholders shall be distributed ratably among the holders of Series D
Convertible Preferred Stock and any other class or series of stock ranking equal
to the Series D Convertible Preferred Stock as to distribution of assets upon
liquidation in accordance with the sums that would be payable on such
distribution if all sums payable thereon to holders of all shares of such series
were paid in full.  Upon any such liquidation, dissolution or winding up of the
Corporation, after the holders of Series D Convertible Preferred Stock and any
other class or series of stock ranking equal to the Series D Convertible
Preferred Stock as to distribution of assets upon liquidation shall have been
paid in full the amounts to which they shall be entitled, the remaining net
assets of the Corporation may be distributed to the holders of Common Stock and
any other class or series of stock ranking junior to the Series D Convertible
Preferred Stock as to the distribution of assets upon liquidation.  Written
notice of such liquidation, dissolution or winding up, stating a payment date,
the amount of the Liquidation Payment and the place where said Liquidation
Payment shall be payable, shall be given by mail, postage prepaid, not less than
30 days prior to the payment date stated therein, to the holders of record of
Series D Convertible Preferred Stock, such notice to be addressed to each such
holder at his post office address as shown by the records of the Corporation.  A
consolidation or merger of the Corporation into or with any other corporation or
corporations shall not be deemed to be a liquidation, dissolution or winding up
of the Corporation within the meaning of the provisions of this Section 4.

          The Corporation's Series D Convertible Preferred Stock shall rank
equal to its Series A Convertible Preferred Stock, and Series C Convertible
Preferred Stock with respect

                                     - 2 -
<PAGE>
 
to payment upon liquidation.

          5.   Optional Conversion.  Any or all of the shares of Series D
               -------------------                                       
Convertible Preferred Stock shall be convertible at any time and from time to
time until 5:00 p.m., Washington D.C. time, on August 31, 2003 (the "Expiration
Date")(provided however, that such Expiration Date shall not apply, and the
shares of Series D Convertible Preferred Stock shall continue to be convertible,
in the event of an Act of Bankruptcy, as defined in that certain Investment
Agreement dated on or about August 30, 1995 (the "Investment Agreement"), of the
Corporation or in the event of a payment default under the Investment Agreement)
at the option of each holder of record thereof, into fully paid and
nonassessable shares of Common Stock of the Corporation upon surrender to the
Corporation of the certificate or certificates representing the Series D
Convertible Preferred Stock to be converted; and, upon receipt by the
Corporation of such surrendered certificate or certificates with any appropriate
endorsement thereon as may be prescribed by the Board of Directors, such holder
shall be entitled to receive a certificate or certificates representing the
shares of Common Stock into which such shares of Series D Convertible Preferred
Stock are convertible.  Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of Series D Convertible Preferred Stock to be converted, and the person
or persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock as of such date.  The basis for such conversion
shall be the "conversion rate" in effect at the time of conversion, which for
the purposes hereof shall mean the number of shares of Common Stock issuable for
each share of Series D Convertible Preferred Stock surrendered for conversion.
Initially, the conversion rate shall be 1, i.e., 1 share of Common Stock for
                                           ----                             
each share of Series D Convertible Preferred Stock being converted; and such
conversion rate shall be subject to adjustment as provided in Section 8 below.
In connection with effecting any transfer to the Corporation for cancellation of
any Series D Convertible Preferred Stock upon conversion of the same into Common
Stock, if any fractional interest in a share of Common Stock would be
deliverable upon such conversion of Series D Convertible Preferred Stock, the
Corporation shall pay in lieu of such fractional share an amount equal to the
"conversion price" (as defined in the following sentence) of such fractional
share (computed to the nearest one thousandth of a share) in effect at the close
of business on the date of conversion.  As used herein, the term "conversion
price" shall be an amount computed by dividing $1.88 by the conversion rate then
in effect.  Initially, the conversion price shall be $1.88 per share.  The Board
of Directors of the Corporation shall at all times reserve a sufficient number
of authorized but unissued shares of Common Stock, which shall be issued only in
satisfaction of the conversion rights and privileges aforesaid.

          6.   Issue Taxes.  The Corporation shall pay all issue taxes, if any,
               -----------                                                     
incurred in respect of the issue of shares of Common Stock on conversion.  If a
holder of shares surrendered for conversion specifies that the shares of Common
Stock to be issued on conversion are to be issued in a name or names other than
the name or names in which such surrendered shares stand, the Corporation shall
not be required to pay any transfer or other taxes incurred by reason of the
issuance of such shares of Common Stock to the name of another, and if the
appropriate transfer taxes shall not have been paid to the Corporation or

                                     - 3 -

the transfer agent for the Series D Convertible Preferred Stock at the time of
surrender of the shares involved, the shares of Common Stock issued upon
conversion thereof may be registered in the name or names in which the
surrendered shares were registered, despite the instructions to the contrary.

          7.   [Intentionally omitted]

          8.   Adjustment of Conversion Price and Conversion Rate.  The number
               --------------------------------------------------             
and kind of securities issuable upon the conversion of the Series D Convertible
Preferred Stock, the conversion price and the conversion rate shall be subject
to adjustment from time to time upon the happening of certain events as follows:

               (a)  Reorganization, Reclassification.  In the event of a
                    --------------------------------                    
reorganization, share exchange, or reclassification, other than a change in par
value, or from par value to no par value, or from no par value to par value or a
transaction described in subsection (b) or (c) below, each share of Series D
Convertible Preferred Stock shall, after such reorganization, share exchange or
reclassification, be convertible into the kind and number of shares of stock or
other securities or property of the Corporation to which the holder of Series D
Convertible Preferred Stock would have been entitled if the holder had held the
Common Stock issuable upon conversion of his Series D Convertible Preferred
Stock immediately prior to such reorganization, share exchange, or
reclassification.

               (b)  Consolidation, Merger.  In the event of a merger or
                    --------------------- 
consolidation to which the Corporation is a party, each share of Series D
Convertible Preferred Stock shall, after such merger or consolidation, be
convertible into the kind and number of shares of stock and/or other securities,
cash or other property to which the holder of such share of Series D Convertible
Preferred Stock would have been entitled if the holder had held the Common Stock
issuable upon conversion of his share of Series D Convertible Preferred Stock
immediately prior to such consolidation or merger.
 
               (c)  Subdivision or Combination of Shares.  In case outstanding
                    ------------------------------------
shares of Common Stock shall be subdivided or combined, the conversion price
shall be proportionately reduced, in case of subdivision of such shares, as of
the effective date of such subdivision, or as of the date a record is taken of
the holders of Common Stock for the purpose of so subdividing, whichever is
earlier, or shall be proportionately increased, in case of combination of such
shares, as of the effective date of such combination, or as of the date a record
is taken of the holders of Common Stock for the purpose of so combining,
whichever is earlier.

               (d)  Stock Dividends.  In case shares of Common Stock are issued
                    ---------------
as a dividend or other distribution on the Common Stock, then the conversion
price shall be adjusted, as of the date a record is taken of the holders of
Common Stock for the purpose of receiving such dividend or other distribution
(or if no such record is taken, as at the date of such payment or other
distribution), to that price determined by multiplying the conversion price in
effect immediately prior to such payment or other distribution by a fraction (i)
the numerator of which shall be the number of shares of Common Stock outstanding
immediately

                                     - 4 -
<PAGE>
 
prior to such dividend or other distribution, and (ii) the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
after such dividend or other distribution.


          (e)  Issuance of Additional Shares of Common Stock.  If the
               --------------------------------------------- 
Corporation shall issue any Additional Shares of Common Stock (as defined herein
and other than as provided in the foregoing subsections (a) through (d)) for a
consideration per share less than the conversion price in effect on the date of
and immediately prior to such issue, then and in such event, such conversion
price shall be reduced, concurrently with such issue, to a price equal to the
quotient obtained by dividing:

               (i)   an amount equal to (x) the total number of shares of Common
     Stock outstanding immediately prior to such issuance or sale multiplied by
     the conversion price in effect immediately prior to such issuance or sale,
     plus (y) the consideration, if any, received or deemed to be received by
     the Corporation upon such issuance or sale, by

               (ii)  the total number of shares of Common Stock outstanding
     immediately after such issuance or sale.

For purposes of this formula, all shares of Common Stock issuable upon the
exercise of outstanding warrants, options or other rights described in paragraph
(f) below or issuable upon the conversion of the Corporation's outstanding
Series A, Series C and Series D Preferred Stock and any other convertible
securities, shall be deemed outstanding shares of Common Stock.

No adjustment of the conversion price shall be made under this subsection 8(e)
upon the issuance of any Additional Shares of Common Stock which are issued
pursuant to the exercise of any warrants, options or other subscription or
purchase rights or pursuant to the exercise of any conversion or exchange rights
in any convertible securities if any such adjustments shall previously have been
made upon the issuance of any such warrants, options or other rights or upon the
issuance of any convertible securities (or upon the issuance of any warrants,
options or any rights therefor) pursuant to subsections 8(f) or 8(g) hereof.

          (f)  Issuance of Warrants, Options or Other Rights.  If the
               ---------------------------------------------
Corporation at any time shall issue any warrants, options or other rights to
subscribe for or purchase any Additional Shares of Common Stock and the price
per share for which Additional Shares of Common Stock may at any time thereafter
be issuable pursuant to such warrants, options or other rights shall be less
than the conversion price per share in effect immediately prior to such
issuance, then upon such issuance the conversion price shall be adjusted as
provided in subsection 8(e) hereof on the basis that the aggregate consideration
for the Additional Shares of Common Stock issuable pursuant to such warrants,
options or other rights, shall be deemed to be the consideration received by the
Corporation for the issuance of such warrants, options, or other rights plus the
minimum consideration to be received by the Corporation for the issuance of
Additional Shares of Common Stock pursuant

                                     - 5 -
<PAGE>
 
to such warrants, options, or other rights.

          (g)  Issuance of Convertible Securities.  In case the Corporation
               ----------------------------------
shall issue any securities convertible into Common Stock and the consideration
per share for which Additional Shares of Common Stock may at any time thereafter
be issuable pursuant to the terms of such convertible securities shall be less
than the conversion price per share in effect immediately prior to such
issuance, then upon such issuance the conversion price shall be adjusted as
provided in subsection 8(e) hereof on the basis that (i) the maximum number of
Additional Shares of Common Stock necessary to effect the conversion or exchange
of all such convertible securities shall be deemed to have been issued as of the
date of issuance of such convertible securities, and (ii) the aggregate
consideration for such maximum number of Additional Shares of Common Stock shall
be deemed to be the consideration received by the Corporation for the issuance
of such convertible securities plus the minimum consideration received by the
Corporation for the issuance of such Additional Shares of Common Stock pursuant
to the terms of such convertible securities. No adjustment of the conversion
price shall be made under this subsection upon the issuance of any convertible
securities which are issued pursuant to the exercise of any warrants, options or
other subscription or purchase rights therefor, if any such adjustment shall
previously have been made upon the issuance of such warrants, options or other
rights pursuant to subsection 8(f) hereof.

          (h)  Adjustment of Conversion Rate.  Upon each adjustment of the
               -----------------------------                              
conversion price under the provisions of this Section 8, the conversion rate
shall be adjusted to an amount determined by dividing $1.88 by such adjusted
conversion price.

          (i)  Other Provisions Applicable to Adjustments Under this Section.
               -------------------------------------------------------------  
The following provisions will be applicable to the making of adjustments in
conversion price hereinabove provided in this Section 8:

               (i)  Computation of Consideration.  To the extent that any
                    -----------------------------                        
     Additional Shares of Common Stock or any convertible securities or any
     warrants, options or other rights to subscribe for or purchase any
     Additional Shares of Common Stock or any convertible securities shall be
     issued for a cash consideration, the consideration received by the
     Corporation therefor shall be deemed to be the amount of the cash received
     by the Corporation therefor, or, if such Additional Shares of Common Stock
     or convertible securities are offered by the Corporation for subscription,
     the subscription price, or, if such Additional Shares of Common Stock or
     convertible securities are sold to underwriters or dealers for public
     offering without a subscription offering, or through underwriters or
     dealers for public offering without a subscription offering, the initial
     public offering price, in any such case excluding any amounts paid or
     incurred by the Corporation for and in the underwriting of, or otherwise in
     connection with the issue thereof.  To the extent that such issuance shall
     be for a consideration other than cash, then, the amount of such
     consideration shall be deemed to be the fair value of such consideration at
     the time of such issuance as determined in good faith by the Corporation's
     board of directors.  The consideration for any Additional Shares of Common
     Stock issuable pursuant to any warrants, options or other rights to
     subscribe for or purchase the same shall be the consideration

                                     - 6 -
<PAGE>
 
     received by the Corporation for issuing such warrants, options or other
     rights, plus the additional consideration payable to the Corporation upon
     the exercise of such warrants, options or other rights.  The consideration
     for any Additional Shares of Common Stock issuable pursuant to the terms of
     any convertible securities shall be the consideration paid or payable to
     the Corporation in respect of the subscription for or purchase of such
     convertible securities, plus the additional consideration, if any, payable
     to the Corporation upon the exercise of the right of conversion or exchange
     of such convertible securities.  In case of the issuance at any time of any
     Additional Shares of Common Stock or convertible securities in payment or
     satisfaction of any dividend upon any class of stock preferred as to
     dividends in a fixed amount, the Corporation shall be deemed to have
     received for such Additional Shares of Common Stock or convertible
     securities a consideration equal to the amount of such dividend so paid or
     satisfied.

               (ii)   Readjustment of Conversion Price.  Upon the expiration of
                      --------------------------------                         
     the right to convert or exchange any convertible securities, or upon the
     expiration of any rights, options or warrants, without conversion, exchange
     or exercise, the issuance of which convertible securities, rights, options
     or warrants effected an adjustment in the conversion price, such conversion
     price shall forthwith be readjusted and thereafter be the price which it
     would have been (but reflecting any other adjustments in the conversion
     price made pursuant to the provisions of this Section 8 after the issuance
     of such convertible securities, rights, options or warrants) had the
     adjustment of the conversion price made upon the issuance or sale of such
     convertible securities or issuance of rights, options or warrants been made
     on the basis of the issuance only of the number of Additional Shares of
     Common Stock actually issued upon conversion or exchange of such
     convertible securities, or upon the exercise of such rights, options or
     warrants, and thereupon only the number of Additional Shares of Common
     Stock actually so issued, if any, shall be deemed to have been issued and
     only the consideration actually received by the Corporation (computed as
     set forth in subsection (i) hereof) shall be deemed to have been received
     by the Corporation.  If the purchase price provided for in any rights,
     options or warrants, or the additional consideration (if any) payable upon
     the conversion or exchange of any convertible securities, or the rate at
     which any convertible securities are convertible into or exchangeable for
     shares of Common Stock changes at any time (other than under or by reason
     of provisions designed to protect against dilution), the conversion price
     in effect at the time of the change shall be adjusted to the conversion
     price that would have been in effect at such time had such rights, options,
     warrants or convertible securities still outstanding provided for such
     changed purchase price, additional consideration or conversion rate, as the
     case may be, at the time initially granted, issued or sold.

               (iii)  Treasury Shares.  The number of shares of Common Stock at
                      ---------------                                          
     any time outstanding shall not include any shares thereof then directly or
     indirectly owned or held by or for the accounts of the Corporation.

               (iv) Other Action Affecting Common Stock.  In case the
                    -----------------------------------              

                                     - 7 -
<PAGE>
 
     Corporation shall take any action affecting the outstanding number of
     shares of Common Stock, other than an action described in any of the
     foregoing subsections 8(a) to 8(g) hereof, inclusive, which in the opinion
     of the Corporation's board of directors would have a materially adverse
     effect upon the rights of the holders of the Series D Convertible Preferred
     Stock, the conversion price shall be adjusted in such manner and at such
     time as the board of directors on the advice of the Corporation's
     independent public  accountants may in good faith determine to be equitable
     in the circumstances.

                    (v)  Certain Definitions.  For purposes of this Section 8:
                         -------------------                                  

                         a)  The term "Common Stock" shall be deemed to mean (i)
          the Common Stock, $.001 par value, and (ii) the stock of the
          Corporation of any other class, or series within such a class, whether
          now or hereafter authorized, which is not convertible or exercisable
          into or for Common Stock, $.001 par value, and has the right to
          participate in the distribution of either earnings or assets of the
          Corporation without limit as to the amount or percentage.

                         b)  The term "Additional Shares of Common Stock" shall
          mean all shares of Common Stock issued by the Corporation after the
          initial issuance of the Series D Convertible Preferred Stock, except:

                               (i)    shares of Common Stock issuable upon
          conversion of the Series D Convertible Preferred Stock, the Series C
          Convertible Preferred Stock or the Series A Convertible Preferred
          Stock;

                               (ii)   shares of Common Stock, warrants, options
          and other rights to purchase shares of Common Stock and securities
          convertible into shares of Common Stock, issued to officers, directors
          and employees of, and consultants to, the Corporation as compensation
          for bona fide services provided to the Corporation by such persons;

                               (iii)  shares of Common Stock issuable upon
          exercise of warrants issued on or outstanding on the original issue
          date of the Series D Convertible Preferred Stock; and

                               (iv)   shares of Common Stock to be issued to the
          stockholders of Educo, Inc.

               No reduction of the conversion price shall be made if the amount
          of any such reduction would be an amount less than $.05, but any such
          amount shall be carried forward and reduction with respect thereof
          shall be made at the time of and together with any subsequent
          reduction which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate $.05 or more.

                                     - 8 -
<PAGE>
 
                             (j)  Special Adjustment.   In the event that on
                                  ------------------
the seventh anniversary date (the "Determination Date") of the original issue
date of the Series D Convertible Preferred Stock, the Fair Market Value (as
defined below) of a share of Common Stock is less than the conversion price per
share, the Corporation shall adjust the conversion price to equal the Fair
Market Value of a share of Common Stock. This provision shall not affect the
conversion price and conversion rate applied to any conversions of the Series D
Convertible Preferred Stock prior to the Determination Date.

                                  "Fair Market Value" of a share of Common
Stock as of the Determination date shall mean:

                                  (i)    If the Corporation's Common Stock is
traded on an exchange or is quoted on The Nasdaq National Market, then the
average of the sale prices reported for the 20 business days immediately
preceding the Determination Date.

                                  (ii)   If the Corporation's Common Stock is
not traded on an exchange or on The Nasdaq National Market but is traded in the
over-the-counter market, then the average of the means of the closing bid and
asked prices reported for the 20 business days immediately preceding the
Determination Date.

                                  (iii)  If the Corporation's Common Stock is
not publicly traded, then the Appraised Fair Market Value, pursuant to
subparagraph (iv) below.

                                  (iv)   Appraised Fair Market Value. The
"Appraised Fair Market Value" shall be determined by the following method:

                                         (A)  If the Corporation and the holders
of shares of Series D Convertible Preferred Stock agree on the selection of an
appraiser, such appraiser shall determine a value, and such value shall be the
Appraised Value;

                                         (B)  If the Corporation and the holders
shall not agree on the selection of an appraiser within 10 days, each of the
Company and the holders, as a group, shall select an appraiser who shall each
determine a value;

                                         (C)  If the values determined by such
two appraisers are the same (or the lower value determined by an appraiser is
within one percent of the value determined by the other), then such value (or
the average of such two values) shall be the Appraised Fair Market Value;

                                         (D)  If the foregoing two appraisals
are not the same and the lower value determined by an appraiser differs by more
than one percent of the value determined by the other, then the appraisers shall
together select a third appraiser to determine a value;
 
                                         (E)  If the determination of the third
appraiser

                                     - 9 -
<PAGE>
 
is greater than the largest of the first two appraisals or less than the
smallest of the first two appraisals, then the average of the first two
appraisals shall be the Appraised Fair Market Value; and

                                         (F)  If the determination of the third
appraiser is between the first two appraisals, then the average of the third
appraisal and the closest of the first two appraisals shall be the Appraised
Fair Market Value.

Each party shall pay the fees and costs of the appraiser it selects, and the
fees and costs of the third appraiser, if any, shall be paid equally by Company
and the holders.


                               (k)  Notices of Adjustments.    Whenever the 
                                    ----------------------        
conversion rate and conversion price is adjusted as herein provided, an officer
of the Corporation shall compute the adjusted conversion rate and conversion
price in accordance with the foregoing provisions and shall prepare a written
instrument setting forth such adjusted conversion rate and conversion price and
showing in detail the facts upon which such adjustment is based, and such
written instrument shall promptly be delivered to the record holders of the
Series D Convertible Preferred Stock.

          9.  Notices of Record Dates and Effective Dates.  In case at any time:
              -------------------------------------------
(a) the Corporation shall declare a dividend (or any other distribution) on the
Common Stock payable otherwise than in shares of Common Stock; or (b) the
Corporation shall authorize the granting to the holders of Common Stock of
rights to subscribe for or purchase any shares of capital stock of any class or
any other rights; or (c) of any reorganization, share exchange or
reclassification of the capital stock of the Corporation (other than a
subdivision or combination of outstanding shares of Common Stock), or of any
consolidation or merger to which the Corporation is party or of the sale, lease
or exchange of all or substantially all of the property of the Corporation; or
(d) of the voluntary or involuntary dissolution, liquidation or winding up of
the Corporation, then the Corporation shall cause to be mailed to the record
holders of the Series D Convertible Preferred Stock at least 20 days prior to
the applicable record date or effective date thereafter specified, a notice
stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights, or, if a record is not to be taken, the date
as of which the holders of record of Common Stock to be entitled to such
dividend, distribution or rights are to be determined or (ii) the date on which
such reclassification, reorganization, share exchange, consolidation, merger,
sale, lease, exchange, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that holders of record
of Common Stock shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,
reorganization, share exchange, consolidation, liquidation, merger, sale, lease,
exchange, dissolution, liquidation or winding up.

          10.  Voting Rights.  Holders of Series D Convertible Preferred Stock
               -------------

required by law, at any annual or special meeting of the Corporation's
stockholders, or in connection with any written consent in lieu of any such
meeting, each outstanding share of Series D

                                     - 10 -
<PAGE>
 
Convertible Preferred Stock shall be entitled to the number of votes equal to
the number of full shares of Common Stock into which such share of Series D
Convertible Preferred Stock is then convertible (calculated by rounding any
fractional share down to the nearest whole number).  Initially, each share of
Series D Convertible Preferred Stock shall have one vote.  Except as otherwise
required by law, the Series D Convertible Preferred Stock, the Series C
Convertible Preferred Stock, the Series A Convertible Preferred Stock and the
Common Stock shall vote together on each matter submitted to the stockholders,
and not by separate class or series.

          B.   The recitals and resolutions contained herein have not been

          IN WITNESS WHEREOF, the undersigned has executed this Certificate this
30th day of August, 1995.

advance under the Line by delivering to the bank officer designated by Bank no
later than 11:00 a.m. Philadelphia time on the Business Day such advance is
requested to be funded, such documentation as Bank may from time to time
require.  Subject to the terms and conditions of this Agreement, Bank will make
the proceeds of an advance available to Obligors by crediting such proceeds to
any Obligor's deposit account with Bank or by advancing such proceeds to such
Persons as Obligors shall designate.  Each request for an advance under the Line
shall be conclusively presumed to be made by a person authorized by Obligors to
do so.  However, Bank may require that specified officers of Obligors sign each
borrowing base certificate.

     1.6  CLOSING.  Closing hereunder will take place at the offices of Lesser &
          -------

     Obligors will execute a letter of credit application and letter of credit
agreement, and such other documents as may be required by Bank in connection
with the issuance of letters of credit hereunder.  The outstanding face amount
of all letters of credit issued by Bank pursuant hereto will reduce Obligors'
ability to borrow under the Line as if such face amount were an advance under
the Line.  In the event that Bank pays any sums due pursuant to such letters of
credit for any reason, such payment shall be deemed to be an advance under the
Line repayable by Obligors pursuant to the terms hereof.

     In the event that the Line is terminated for any reason or demand is made
thereunder, Obligors will deposit with Bank an amount equal to the face amount
of all letters of credit then outstanding which have been issued hereunder, plus
all fees related thereto or to accrue thereunder.  Such funds will be held by
Bank as cash collateral to secure Obligors' obligations hereunder.

          ------------                                                       
Event of Default, at the option of Bank after ten (10) days notice to Obligors,
interest will accrue on the outstanding principal balance of the Line and the
Term Loan at a per annum rate which is three percent (3%) in excess of the
highest rate in effect for the Line and the Term Loan, respectively,  at the
time the Event of Default occurs.  During the continuance of any Event of
Default, Obligors shall no longer have the ability to elect interest rate
options.

     2.14 POST JUDGMENT INTEREST.  Any judgment obtained for sums due hereunder
          ----------------------                                               
or under the Loan Documents will accrue interest at the applicable default rate
set forth above until paid.

     2.15 CALCULATION.  Interest will be computed on the basis of a year of 360
          -----------                                                          
days and paid for the actual number of days elapsed.

     2.16 LIMITATION OF INTEREST TO MAXIMUM LAWFUL RATE.  In no event will the
          ---------------------------------------------                       
rate of interest payable hereunder exceed the maximum rate of interest permitted
to be charged by applicable law (including the choice of law rules) and any
interest paid in excess of the permitted rate will be refunded to Obligors.
Such refund will be made by application of the excessive amount of interest paid
against any sums outstanding hereunder and will be applied in such order as Bank
may determine.  If the excessive amount of interest paid exceeds the sums
outstanding, the portion exceeding the sums outstanding will be refunded in cash
by Bank.  Any such crediting or refunding will not cure or waive any default by
Obligors.  Obligors agree, however, that in determining whether or not any
interest payable hereunder exceeds the highest rate permitted by law, any non-
principal payment, including without limitation prepayment fees and late
charges, will be deemed to the extent permitted by law to be an expense, fee,
premium or penalty rather than interest.

     2.17 REQUEST BY ONE OBLIGOR.  Any requests to be made by Obligors under

will be equal to that set forth in

                                     -10-

terms hereof shall be due and payable immediately.

accruing interest at the Term LIBOR Rate which are prepaid with borrowed money,
equity infusions or other funds not obtained from Obligors' operations (which
operations shall include sales of assets permitted under SECTION 6.5 below),

which with the giving of notice or the passage of time or both would become an
Event of Default shall have occurred, Obligors shall not be required to pay the
prepayment premiums set forth in SECTIONS 3.9(C)(II) AND 3.9(C)(III) above.
                                 -----------------------------------       

     In the event Bank exercises its right to accelerate payments under the Term
Loan following an Event of Default, any tender of payment of the amount
necessary to repay all or part of the Term Loan made thereafter at any time by
Obligors, their successors or assigns or by anyone on behalf of Obligors and any
receipt by Bank of proceeds of Collateral in payment of the Term Loan shall be
deemed to be a voluntary prepayment and in connection therewith Bank shall be
entitled to receive the premium required to be paid under the foregoing
prepayment restrictions.

     3.10 PAYMENT METHOD.  Obligors irrevocably authorize Bank to debit all
          --------------                                                   
payments required to be made by Obligors hereunder, under the Line or the Term
Loan, on the date due, from any deposit account maintained by Obligors or any of
them, with Bank; provided, however, prior to the occurrence of an Event of
                 --------  -------                                        
Default or an event which with the giving of notice or the passage of time or
both would become an Event of Default, Obligors may designate which accounts
maintained with Bank shall be so debited.  Otherwise, Obligors will be obligated
to make such payments directly to Bank.  All payments are to be made in
immediately available funds.  If Bank accepts payment in any other form, such
payment shall not be deemed to have been made until the funds comprising such
payment have actually been received by or made available to Bank.

     3.11 APPLICATION OF PAYMENTS.  Any and all payments on account of the Bank
          -----------------------                                              
Indebtedness will be applied to accrued and unpaid interest, outstanding
principal and other sums due hereunder or under the Loan Documents, in such
order as Bank, in its discretion, elects.  If Obligors make a payment or
payments and such payment or payments, or any part thereof, are subsequently
invalidated, declared to be fraudulent or preferential, set aside or are
required to be repaid to a trustee, receiver, or any other person under any
bankruptcy act, state or federal law, common law or equitable cause, then to the
extent of such payment or payments, the obligations or part thereof hereunder
intended to be satisfied shall be revived and continued in full force and effect
as if said payment or payments had not been made.

     3.12 LOAN ACCOUNT.  Bank will open and maintain on its books a loan account
          ------------                                                          
(the "LOAN ACCOUNT") with respect to advances made, repayments, prepayments, the
computation and payment of interest and fees and the computation and final
payment of all other amounts due and sums paid to Bank under this Agreement.
Except in the case of manifest error in computation, the Loan Account will be
conclusive and binding on the Obligors as to the amount at any time due to Bank
from Obligors under this Agreement or the Notes.

     3.13 INDEMNITY; LOSS OF MARGIN.  Obligors will indemnify Bank against any
          -------------------------                                           
direct loss or expense which Bank sustains or incurs as a consequence of an
Event of Default, including, without limitation, any failure of Obligors to pay
when due (at maturity, by acceleration or otherwise) any principal, interest,
fee or any other amount due under this Agreement or the other Loan Documents.
If Bank sustains or incurs any such loss or expense it will from time to time
notify Obligors in writing of the amount determined in good faith by the Bank to
be necessary to indemnify Bank for the loss or expense.  Such amount will be due
and payable by Obligors to Bank within ten (10) days after presentation by Bank
of a statement setting forth a brief explanation of and Bank's calculation of
such amount, which statement shall be conclusively deemed correct absent
manifest error.  Any amount payable to the Bank under this Section will bear
interest at the default rate payable under the Line from the due date until
paid, both before and after judgment.

     In the event that any present or future law, rule, regulation, treaty or
official directive or the interpretation or application thereof by any central
bank, monetary authority or governmental authority, or the compliance with any
guideline or request of any central bank, monetary authority or governmental
authority (whether or not having the force of law):

          (A)  subjects Bank to any tax with respect to any amounts payable
under this Agreement or the other Loan Documents by Obligors or otherwise with
respect to the transactions contemplated under this Agreement or the other Loan
Documents (except for taxes on the overall net income of Bank imposed by the
United States of America or any political subdivision thereof); or

          (B)  imposes, modifies or deems applicable any deposit insurance,
reserve, special deposit, capital maintenance, capital adequacy, or similar
requirement against assets held by, or deposits in or for the account of, or
loans or advances or commitment to make loans or advances by, or letters of
credit issued or commitment to issue letters of credit by, the Bank; or

          (C)  imposes upon Bank any other condition with respect to advances or
extensions of credit or the commitment to make advances or extensions of credit
under this Agreement,

and the result of any of the foregoing is to increase the costs of Bank, reduce
the income receivable by or return on equity of Bank or impose any expense upon
Bank with respect to any advances or extensions of credit or commitments to make
advances or extensions of credit under this Agreement, Bank shall so notify
Obligors in writing.  Obligors agree to pay Bank the amount of such increase in
cost, reduction in income, reduced return on equity or capital, or additional
expense (such amount being the "REIMBURSEMENT AMOUNT") suffered or incurred by
Bank within thirty (30) days after presentation by Bank of a statement
concerning such increase in cost, reduction in income, reduced

                                     -14-
<PAGE>
 
return on equity or capital, or additional expense.  Such statement shall set
forth a brief explanation of the Reimbursement Amount and Bank's calculation of
the Reimbursement Amount (in determining such Reimbursement Amount the Bank may
use any reasonable averaging and attribution methods), which statement shall be
conclusively deemed correct absent manifest error.  Notwithstanding the
foregoing, if an event of the nature described in SECTION 3.13(A), (B) OR (C)
                                                  ---------------------------
above occurs, Obligors shall have the right to repay in full all Bank
Indebtedness without any prepayment premium (other than an amount equal to the
economic loss suffered by Bank with respect to that portion of the Bank
Indebtedness accruing interest at the Line LIBOR Rate or the Term LIBOR Rate at
the time of such prepayment), provided that, (i) within thirty (30) days of the
presentation of such statement to Obligors, Obligors pay to Bank the
Reimbursement Amount then due Bank through such date, (ii) such repayment to
Bank is made on or before the one hundred twentieth (120th) day following the
presentation of such statement to Obligors, and (iii) at the time of such
repayment, Obligors shall also pay to Bank the Reimbursement Amount then due
Bank through the date of such repayment.

     If the amount set forth in such statement is not paid in full as set forth
above within thirty (30) days after such presentation of such statement, or the
amount due in connection with a repayment of the Bank Indebtedness as described
above is not paid in full within one hundred twenty (120) days after such
presentation of such statement, interest will be payable on the unpaid amount at
the default rate payable under the Line from the due date until paid, both
before and after judgment.

delivered to Bank, with appropriate endorsement and assignment to Bank with full

property) used or useful in the conduct of its business in good working order
and condition, reasonable wear and tear excepted, and will pay and discharge
when due the cost of repairs to and maintenance of the same.

     With respect to any and all trademarks, registrations, copyrights, patents,
patent rights and applications for any of the foregoing, each Obligor shall
maintain and protect the same and shall take and assert any and all remedies
available to that Obligor to prevent any other Person from infringing upon or
claiming any interest in any such trademarks, registrations, copyrights,
patents, patent rights or application for any of the foregoing.

     Obligors will notify Bank immediately of (a) the creation by any Obligor or
any of its employees (during the course of employment with such Obligor) of any
inventions; (b) any changes or improvements made to an invention created or
owned by any Obligor or any of its employees (during the course of employment

execute and deliver to Bank an agreement permitting Bank to exercise all of any
Obligor's rights in, to and under any patent or trademark owned by any Obligor

insurer acceptable to Bank, in amounts acceptable to Bank (at least adequate to
comply with any co-insurance provisions) and against all such liability and
hazards as are usually carried by entities engaged in the same or a similar
business similarly situated or as may be required by Bank, and in addition, will
carry business interruption insurance in such amounts as may be required by
Bank.  In the case of insurance on any of the Collateral, Obligors shall carry
insurance in the full insurable value thereof and cause Bank to be named as
insured mortgagee with respect to all real property, loss payee (with a lender's
loss payable endorsement) with respect to all personal property, and additional
insured with respect to all liability insurance, as its interests may appear
with thirty (30) days' notice to be given Bank by the insurance carrier prior to
cancellation or material modification of such insurance coverage.

     Obligors shall cause to be delivered to Bank the insurance policies
therefor or in the alternative, evidence of insurance and at least five (5)
business days prior to the expiration of any such insurance, additional policies
or duplicates thereof or in the alternative, evidence of insurance evidencing
the renewal of such insurance and payment of the premiums therefor.  Obligors
shall direct all insurers that in the event of any loss thereunder or the
cancellation of any insurance policy, the insurers shall make payments for such
loss and pay all return or unearned premiums directly to Bank and not to
Obligors, or any of them, and Bank jointly.

     In the event of any loss, Obligors will give Bank immediate notice thereof
and Bank may make proof of loss whether the same is done by Obligors.  Bank is
granted a power of attorney by each Obligor with full power of substitution to
file any proof of loss in any Obligor's or Bank's name, to endorse any Obligor's
name on any check, draft or other instrument evidencing insurance proceeds, and
to take any action or sign any document to pursue any insurance loss claim.
Such power being coupled with an interest is irrevocable.

     In the event of any loss, Bank, at its option, may (a) retain and apply all
or any part of the insurance proceeds to reduce, in such order and amounts as
Bank may elect, the Bank Indebtedness, or (b) disburse all or any part of such
insurance proceeds to or for the benefit of any Obligor for the purpose of
repairing or replacing Collateral after receiving proof satisfactory to Bank of
such repair or replacement, in either case without waiving or impairing the Bank
Indebtedness or any provision of this Agreement.  Any deficiency thereon shall
be paid by Obligors to Bank upon demand.  No Obligor shall take out any
insurance without having Bank named as loss payee or additional insured

disposition of the Collateral, or any part thereof, by Bank after an Event of

purchase all or any part of the Collateral at public or, if permitted by law,
private sale, and in lieu of actual payment of such purchase price, may set-off
the amount of such purchase price against the Bank Indebtedness then owing.  Any
sales of the Collateral may be adjourned from time to time with or without
notice.  The Bank may cause the Collateral to remain on any Obligor's premises
or otherwise or to be removed and stored at premises owned by other persons, at
Borrower's expense, pending sale or other disposition of the Collateral.
Obligors, at Bank's request, shall assemble the Collateral consisting of
inventory and tangible assets and make such assets available to Bank at a place
to be designated by Bank.  Bank shall have the right to conduct such sales on
any Obligor's premises, at Obligors' expense, or elsewhere, on such occasion or

otherwise disposing of the Collateral incurred by Bank in connection therewith
and all other costs and expenses related thereto including attorney fees, shall

surplus realized upon such sale or other disposition, and Obligors shall remain
liable for any deficiency.  The commencement of any action, legal or equitable,
or the rendering of any judgment or decree for any deficiency shall not affect
Bank's security interest in the Collateral.  Obligors agree that Bank has no
obligation to preserve rights to the Collateral against any other parties.  Bank
is hereby granted a license or other right to use, after an Event of Default,
without charge, any Obligor's labels, general intangibles, intellectual
property, equipment, real estate, patents, copyrights, rights of use of any
name, trade secrets, trade names, trademarks, service marks and advertising

the part of Bank to exercise any right, remedy, power or privilege under the
Loan Documents upon the occurrence of any Event of Default or otherwise shall
operate as a waiver thereof or impair any such right, remedy, power or

Section, in the event Obligors fail to pay such amount on demand, Obligors shall
also pay to Bank interest thereon at the highest default rate set forth in

          The final payment hereunder due on September 1, 2000 shall include the
