    WHEREAS, the parties hereto have heretofore entered into the Restructured

    NOW, THEREFORE, the parties hereto agree as follows:

    SECTION 1.  DEFINITIONS; REFERENCES.  Unless otherwise specifically 
defined herein, each term used herein which is defined in the Agreement shall 
have the meaning assigned to such term in the Agreement.  Each reference to 
"hereof ", "hereunder", "herein" and "hereby" and each other similar 
reference and each reference to "this Agreement" and each other similar 
reference contained in the Agreement shall from and after the date hereof 
refer to the Agreement as amended hereby.

    SECTION 2.  BRIDGE LOAN.  The Lenders consent to the execution, delivery 
and performance by the parties thereto of the Term Loan and Guaranty 
Agreement (as amended from time to time, the "Bridge Agreement") to be 
entered into by Cardinal Investment Company, Inc.  (or an affiliated 
partnership or other entity or entities) ("Cardinal"), as lender, the 
Company, as borrower and each of the Obligors, as guarantors, substantially 
in the form of the draft dated January 31, 1996 previously delivered to the 
Lenders, including the granting of Liens by the borrowers and guarantors 
thereunder to secure the loans made thereunder and the loaning by the 
borrowers of the proceeds of such loans to the 



Company. The Lenders also waive Section 6.22 of the Agreement in order to 
allow the Parent to enter into the Definitive Agreement referred to below, it 
being understood that no Obligor shall take any action which would be 
required to be taken pursuant to, or in satisfaction of any condition 
contained in, such Definitive Agreement which is not permitted by the 
Agreement unless and until all necessary amendments or waivers have been 
given or made pursuant to the Agreement.

    SECTION 3.  AMENDMENTS TO COVENANTS AND DEFAULTS.  The Lenders agree that 
as part of the amendment and restatement of the Agreement entered into with 
the consent of each of the parties to the Agreement in connection with the

"Definitive Agreement") among Cardinal Investment Company, Inc., the Parent 
and certain Subsidiaries of the Parent (including the Company) substantially 
in the form of the draft dated January 29, 1996 Previously delivered to the 
Lenders, the covenants set forth in Article VI of the Agreement shall be 
amended substantially as set forth in Annex A hereto and the Events of 
Default set forth in Article VII of the Agreement shall be amended 
substantially as set forth in Annex B hereto.  The effectiveness of such 
amendment and restatement of the Agreement shall be conditioned upon, among 
other things, receipt by the Parent of the proceeds of issuance of at least 
$21,430,000 aggregate principal amount of the Convertible Notes (as defined 
in the Definitive Agreement).

    SECTION 4.  GOVERNING LAW.  This Amendment shall be governed by and 
construed in accordance with the laws of the State of New York.

    SECTION 5.  COUNTERPARTS; EFFECTIVENESS.  This Amendment shall become 
effective as of the date hereof when the Agent shall have received duly 
executed counterparts hereof signed by (i) all parties hereto other than the 
Lenders and (ii) each of the Lenders (or in the case of any party from which 
an executed counterpart shall not have been received, the Agent shall have 
received facsimile, telegraphic, telex or other written confirmation from 
such party). This Amendment may be signed in any number of counterparts, each 
of which shall be an original, with the same effect as if the signatures 
thereto and hereto were upon the same instrument.


                                       2



    IN WITNESS WHEREOF, the parties hereto have caused this Amendment and 
Waiver to be duly executed as of the date first above written.
