     1.   SENIOR EXECUTIVE AND CONSULTANT CONVERTIBLE DEBT PLAN; GRANT
AGREEMENT.  This Convertible Debt Unit has been issued under the terms of (a)
the Company's 1996 Senior Executive and Consultant Convertible Debt Plan (the
"Plan") and (b) the Grant Agreement (the "Grant Agreement") dated as of April
11, 1997 between the Company and Jerry Ballah.  The registered holder hereof is
entitled to the benefits of, and subject to the restrictions contained in, the
Plan and the Grant Agreement, and reference is made thereto for a description of
all rights, remedies and restrictions thereunder.  Neither reference to the Plan
or to the Grant Agreement, nor any provision thereof, shall affect or impair the
absolute and unconditional obligation of the Company to pay, when due, the
principal amount hereof, together with all accrued interest thereon.

     2.   MATURITY.  The principal amount of the Convertible Debt evidenced by
this Convertible Debt Unit shall become due and payable on the Maturity Date, if
not previously converted pursuant to Section 3 hereof.  In the event that the
Maturity Date is not a Business Day, the Convertible Debt evidenced by this
Convertible Debt Unit shall be due and payable on the first following day that
is a Business Day.

     3.   CONVERSION RIGHT.  Subject to the provisions of Section 10(b) of the
Plan, the registered holder may, at any time prior to the Maturity Date, convert
this Convertible Debt Unit into shares of the Company's common stock, par value
$.01 per share (the 



"Common Stock") at the rate (the "Conversion Rate") of one Convertible Debt 
Unit for one share of the Common Stock at the conversion price of one cent 
per share of Common Stock.  The Conversion Rate shall be adjusted as 
described in Section 10(a) of the Plan within twenty (20) days following the 
consummation of any of the transactions described in Section 10(a) of the 
Plan.

     4.   MECHANICS OF CONVERSION.  Before the registered holder of this
Convertible Debt Unit will be entitled to convert the same into shares of the
Common Stock, such holder will surrender this Convertible Debt Unit at the
principal office of the Company, and he will give written notice to the Company
in the form of Exhibit A to the Grant Agreement (the "Conversion Notice")
stating (i) the number of the Convertible Debt Units he wishes to convert into
shares of the Common Stock and (ii) the total conversion price for such number
of shares of the Common Stock.  The registered holder of this Convertible Debt
Unit shall include with such Conversion Notice payment of the total conversion
price.  The Company, as soon as reasonably practicable after its receipt of the
Conversion Notice and payment of the total conversion price, will issue and
deliver at such office to such holder, a certificate for the number of shares of
the Common Stock to which such holder will be entitled as aforesaid and if such
holder has elected to convert less than all of his Convertible Debt Units into
shares of the Common Stock, the Company shall deliver to such holder a new
Convertible Debt Unit in the number of the Convertible Debt Units that he did
not elect to convert.  Such conversion will be deemed to have been made
immediately prior to the close of business on the date that the Company receives
the Conversion Notice and payment of the total conversion price from the
registered holder of this Convertible Debt Unit holder, and such registered
holder will be treated for all purposes as the record holder of such shares of
the Common Stock on such date.  If the conversion is in connection with the
initial public offering of shares of the Common Stock, the conversion will be
conditioned upon the closing with the underwriter or underwriters of the sale of
securities pursuant to such offering, in which event the registered holder of
this Convertible Debt Unit shall not be deemed to have converted his Convertible
Debt Unit until immediately prior to the closing of such sale of securities.

     5.   REDEMPTION.  This Convertible Debt Unit is not subject to redemption
or prepayment by the Company in whole or in part, except as otherwise provided
in Section 3 hereof.

     6.   EVENTS OF DEFAULT.  Each of the following events shall be an Event of
Default hereunder:

          a.   The Company shall fail to pay (i) any interest payment hereon
when due or (ii) the principal hereof on the Maturity Date;


                                          2



          b.   The Company files a voluntary petition under the federal
Bankruptcy Code; or

          c.   An involuntary petition under the federal Bankruptcy Code is
filed against the Company and such involuntary petition is not dismissed within
thirty (30) days of the date that such petition was filed.

     7.   RIGHTS OF THE HOLDER FOLLOWING AN EVENT OF DEFAULT.  Upon the
occurrence of any Event of Default, the registered holder of this Convertible
Debt Unit, in his sole discretion, may do either or both of the following: (i)
declare all principal and interest due on the Convertible Debt evidenced by this
Convertible Debt Unit immediately due and payable without demand, protest,
notice of protest, notice of default, presentment for payment or further notice
of any kind; and (ii) proceed to enforce such other and additional rights and
remedies as the registered holder may have under other agreements with the
Company or applicable law.  The failure of the registered holder to exercise any
of the rights and remedies set forth in the preceding sentence shall not
constitute a waiver of the right to exercise the same on any future date.

     8.   REGISTRATION; TRANSFERABILITY; LOCK-UP AGREEMENT.  This Convertible
Debt Unit shall be registered in a Convertible Debt Unit Register maintained by
the Company. This Convertible Debt Unit is subject to the restrictions on the
transfer set forth in the Grant Agreement.  This Convertible Debt Unit and
shares of the Common Stock issued upon the conversion thereof are subject to
provisions regarding a lock-up agreement set forth in the Grant Agreement and to
the Pledge Agreement of even date herewith between the Company and Jerry Ballah.

     9.   RESERVATION OF COMMON STOCK ISSUABLE UPON CONVERSION.  The Company at
all times will reserve and keep available out of its authorized but unissued
shares of Common Stock solely for the purpose of effecting the conversion of
this Convertible Debt Unit such number of shares of Common Stock as from time to
time shall be sufficient to effect the conversion of all of the Convertible Debt
Units evidenced by this Convertible Debt Unit; and if at any time the number of
authorized but unissued shares of Common Stock is not sufficient to effect the
conversion of all of the Convertible Debt Units evidenced by this Convertible
Debt Unit, in addition to such other remedies as may be available to the
registered holder of this Convertible Debt Unit for such failure, the Company
will take such corporate action as, in the opinion of its counsel, may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as will be sufficient for such purpose.
