in the Credit Agreement.

be made in accordance with the terms and conditions set forth in the Credit
Agreement.  Borrower hereby authorizes Purchaser to record on the schedule(s) to
be annexed to this Convertible Note the date and amount of each Advance
(including the Existing Advance) and agrees that all such notations shall
constitute prima facie evidence of the matters noted.

    2.   PRINCIPAL PAYMENT.  All outstanding principal under this Convertible 
NOTE shall be due and payable in one lump sum on the earliest to occur of (i) 
August 29, 1997, (ii) sixty (60) days after the termination of the Investment 
Agreement or (iii) acceleration of this Convertible Note by Purchaser 
pursuant to an Event of Default (and, if applicable, the expiration of the 
sixty (60) day period as provided in the Credit Agreement) (each a "PAYMENT 
EVENT").  Subject to the automatic conversion of this Convertible Note 
described in in Section 5 below, all payments of principal under this 
Convertible Note are payable in lawful money of the United States to 
Purchaser sent to Purchaser's address as indicated in the Credit Agreement, 
or to such other place as Purchaser may designate in writing, in same day or

Any



amounts not paid when due hereunder shall ear interest at a rate per annum equal
to the Interest Rate (as hereinafter defined) plus three percent (3.00%).

    3.   INTEREST.  Interest shall accrue on the unpaid principal balance of
this Convertible Note outstanding from time to time at a rate per annum equal to
Eleven and One-Quarter percent (11.25%) (the "INTEREST RATE"). All computations
of interest under this Convertible Note shall be based on a year of 365 or 366

    4.   PREPAYMENTS.  This Convertible Note may not be prepaid.

    5.   AUTOMATIC CONVERSION.  Notwithstanding the payment provisions set
forth in Section 2 above, upon the Closing, the outstanding principal under this
Convertible Note shall automatically convert into Two Million Four Hundred
Ninety-Nine Thousand Six Hundred Sixty-Four (2,497,184) shares of Common Stock
of UCB.  On and after such automatic conversion and payment by Borrower of all
accrued interest in accordance with Section 3 above, this Convertible Note shall
be deemed to be no longer outstanding, and all rights with respect hereto shall
forthwith cease and terminate, except the right of Purchaser to receive the
Common Stock of UCB to which it shall be entitled upon conversion hereof.  Any
such conversion shall be deemed to have been made immediately prior to the close
of business on the date of conversion, and Purchaser upon such conversion shall
be treated for all purposes as the record holder of such Common Stock upon such
date.

    6.   MAXIMUM AMOUNT.  Notwithstanding anything in this Convertible Note,
the Credit Agreement or any other Credit Document to the contrary, nothing
contained in this Convertible Note, the Credit Agreement or any other Credit
Document shall be deemed to require the payment by Borrower of interest on the
indebtedness evidenced by this Convertible Note in excess of the  amount which
Purchaser may lawfully contract to charge under applicable usury and other laws
(the "MAXIMUM LEGAL RATE").  All agreements between Borrower and Purchaser are
expressly limited so that in no contingency or event shall the amount paid or
agreed to be paid by Borrower hereunder exceed the Maximum Legal Rate.  If,
under any circumstances whatsoever, the fulfillment of any obligation under this
Convertible Note, the Credit Agreement or any other Credit Document shall
involve exceeding the Maximum Legal Rate, the obligation to be fulfilled by
Borrower shall be reduced to the minimum amount required so that such obligation
shall not exceed the Maximum Legal Rate.  This Section 6 shall control every
other provision of this Convertible Note, the Credit Agreement and any other
Credit Document.
