         3.       Ranking. This Note and all other Notes shall rank equally
(pari passu) among themselves as to all rights.

         4.       Mechanics of Conversion. Subject to Sections 2.6(b) and 2.7 of
the Note Purchase Agreement, a Holder of the Medtronic Additional Note may
convert it into shares of Company Common Stock at any time during the period
stated in, and as otherwise provided for in Section 2.6(b) or 2.7 of the Note
Purchase Agreement. The conversion of this Note shall be conducted in the
following manner:

                  (a)      Holder's Delivery Requirements. To convert this Note
(in whole or in part) into shares of Company Common Stock on any date, the
Holder shall transmit by facsimile (or otherwise deliver), on or prior to 11:59
p.m., New York City Time, on such date, a copy of either (A) a fully completed
Conversion Period Notice in the event of a conversion pursuant to Section 2.6(b)
or (B) a fully completed Default Conversion Notice in the event of a conversion
pursuant to Section 2.7, in each case executed by the Holder in the form
attached hereto as Exhibit A-1 and Exhibit A-2 (each a "CONVERSION NOTICE") to
the Borrower and shall surrender this Note to a common carrier for delivery to
the Borrower as soon as practicable following such date.

                  (b)      Company's Response. Upon receipt by the Borrower of
copy of a Conversion Notice, the Borrower shall (A) as soon as practicable, but
in any event within one (1) Business Day, send, via facsimile, a confirmation of
receipt of such Conversion Notice to such holder and shall process such
Conversion Notice in accordance with the terms herein and (B) then on or before
the second (2nd) Business Day following the date of receipt by the Borrower of
such Conversion Notice (the "SHARE DELIVERY DATE"), the Borrower shall issue and
deliver to the address as specified in the Conversion Notice, a certificate,
registered in the name of the Holder or its designee, for the number of shares
of Company Common Stock to which the Holder shall be entitled. If the specified
principal amount submitted for conversion is less than the then Outstanding
Principal Amount of this Note, then the Borrower shall, as soon as practicable
and in no event later than three Business Days after receipt of the Note (the
"NOTE DELIVERY DATE") and at its own expense, issue and deliver to the holder a
new Note representing the Outstanding Principal Amount not converted. The
effective date of conversion (the "CONVERSION DATE") shall be deemed to be the
date on which the Borrower receives by facsimile the Conversion Notice, and the
person or persons entitled to receive the shares of Company Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Company Common Stock on such date. Upon
surrender of a Note that is converted in part, the Borrower shall authenticate
for the holder a new Note equal in principal amount to the unconverted portion
of the Note surrendered. If this Note is converted in part, the remaining
portion of this Note not so converted shall remain entitled to the conversion
rights provided herein. Notwithstanding anything to the contrary expressed or
implied herein or in the Note Purchase Agreement, in the event that a Conversion
Notice is given in accordance herewith on or prior to the date on the 30-day
prepayment notice period referred to Section 3.1(a) of the Note Purchase
Agreement expires, then, in such event, the Borrower shall not be entitled to
prepay this Note and the Holder shall be entitled to convert this Note, in whole
or in part, as stated in such Conversion Notice.

                  (c)      Equity Financing Conversion. In the event of a
conversion of this Note pursuant to Section 2.8 of the Note Purchase Agreement,
(i) this Note shall automatically and without notice or any further action by
any party, convert into that number of shares of equity securities of the
Company as provided for in Section 2.8 of the Note Purchase Agreement, (ii) the
Borrower shall issue and deliver to the address of the Holder as set forth in
the Note Purchase Agreement, a certificate, registered in the name of the Holder
or its designee, for the number of shares of equity securities of the Company to
which the Holder shall be entitled and (iii) the Outstanding Principal Amount
shall automatically and without notice or any further action by any party, be
reduced on the date of such conversion by the dollar amount of the then
Outstanding Principal Amount that is converted at such time.

         5.       Adjustments to Conversion Price.


                                      -2-

<PAGE>

                  (a)      Adjustment of Conversion Price upon Subdivision or
Combination of Company Common Stock. If the Borrower at any time subdivides (by
any stock split, stock dividend, recapitalization or otherwise) its outstanding
shares of Company Common Stock into a greater number of shares, the Conversion
Price in effect immediately prior to such subdivision will be proportionately
reduced. If the Borrower at any time combines (by combination, reverse stock
split or otherwise) its outstanding shares of Company Common Stock into a
smaller number of shares and the Conversion Price in effect immediately prior to
such combination will be proportionately increased.

                  (b)      Notices.

                           (i)      Immediately upon any adjustment of the
Conversion Price pursuant to this Section 5, the Borrower will give written
notice thereof to the Holder, setting forth in reasonable detail, and
certifying, the calculation of such adjustment.

                           (ii)     The Borrower will give written notice to the
Holder at least ten (10) Business Days prior to the date on which the Borrower
closes its books or takes a record (A) with respect to any dividend or
distribution upon the Company Common Stock, (B) with respect to any pro rata
subscription offer to holders of Company Common Stock or (C) for determining
rights to vote with respect to any Organic Change (as hereinafter defined),
dissolution or liquidation, provided that such information shall be made known
to the public prior to or in conjunction with such notice being provided to such
holder.

                           (iii)    The Borrower will also give written notice
to the Holder at least ten (10) Business Days prior to the date on which any
Organic Change, dissolution or liquidation will take place, provided that such
information shall be made known to the public prior to or in conjunction with
such notice being provided to the Holder.

                  (c)      Reorganization, Reclassification, Consolidation,
Merger or Sale. Any recapitalization, reorganization, reclassification,
consolidation, merger, sale of all or substantially all of the Borrower's assets
to another Person or other transaction which is effected in such a way that
holders of Company Common Stock are entitled to receive (either directly or upon
subsequent liquidation) stock, securities or assets with respect to or in
exchange for Company Common Stock is referred to herein as an "ORGANIC CHANGE."
Prior to the consummation of any (i) sale of all or substantially all of the
Borrower's assets to an acquiring Person or (ii) other Organic Change following
which the Borrower is not a surviving entity, the Borrower will secure from the
Person purchasing such assets or the successor, or, if applicable, the parent of
the successor, resulting from such Organic Change (in each case, the "ACQUIRING
ENTITY") a written agreement (in form and substance reasonably satisfactory to
the holders of at least a majority of the Outstanding Principal Amount of the
Notes then outstanding) to deliver to each holder of Notes in exchange for such
shares, a security of the Acquiring Entity evidenced by a written instrument
substantially similar in form and substance to the Notes, including, without
limitation, having a principal amount equal to the Outstanding Principal Amount
and being of rank equal to the Notes held by such holder, and reasonably
satisfactory to the holders of at least a majority of the Outstanding Principal
Amount of the Notes then outstanding. Prior to the consummation of any other
Organic Change, the Borrower shall make appropriate provision (in form and
substance reasonably satisfactory to the holders of at least a majority of the
Outstanding Principal Amount of the Notes then outstanding) to insure that each
of the holders of the Notes will thereafter have the right to acquire and
receive in lieu of or in addition to (as the case may be) the shares of Company
Common Stock immediately theretofore acquirable and receivable upon the
conversion of such holder's Notes such shares of stock, securities or assets
that would have been issued or payable in such Organic Change with respect to or
in exchange for the number of shares of Company Common Stock which would have
been acquirable and receivable upon the conversion of such holder's Notes as of
the date of such Organic Change (without taking into account any limitations or
restrictions on the convertibility of the Notes).
