endorsement of the Units.

        (4)     The Offering is intended to be exempt from registration under

        7.      CONVERSION.

                (a)     CONVERSION OF THE NOTE.  Upon (i) the  authorization  of
the Company's amended and restated Certificate of Incorporation by the Company's
stockholders  and (ii) the filing of the  Certificate of  Designations  with the
Secretary of State of the State of Delaware (the "EFFECTIVE  DATE"), and subject
to the Company  complying  with the mechanics of conversion set forth in Section
7(b)  hereof,  the  outstanding  Principal of this Note shall  automatically  be
converted into shares of Preferred Stock at the preferred stock conversion price
of $10 per share. Upon conversion, all accrued but unpaid Interest shall be paid
to the Holder in cash,  by check  delivered  to such  Holder at the  address set
forth on the signature page hereto.

                (b)     MECHANICS  OF   CONVERSION.   Promptly   following   the
EffectiveDate,  the Company shall  provide  notice to the Holder  thereof.  Upon
delivery  by the Holder of this Note to the  Company  as  provided  herein,  the
Company shall deliver to such Holder a  certificate,  dated the Effective  Date,
representing  the  shares  of  Preferred  Stock  into  which  this Note has been
converted.

                (c)     NO FRACTIONAL SHARES; RELEASE OF OBLIGATIONS UNDER NOTE.
No fractional  Note Shares shall be issued upon conversion of the portion of the
Principal  of this Note as the case may be, in  accordance  with this Section 7.
Upon  conversion of the Principal of this Note, the due issuance of Note Shares,
and the  payment  to the  Holder  of the  accrued  and  unpaid  Interest  to the
Effective  Date,  the Company shall be forever  released from the portion of its
obligations, undertakings and liabilities under this Note so converted.

                (d)     ISSUANCE OF  CERTIFICATES;  ISSUANCE TAX.  Promptly upon
conversion  of  the  Principal  of  this  Note  (and  all  other  amounts  owing
hereunder),  as the case may be, in accordance  with this Section 8, the Company
shall issue to the Holder  certificates  representing  the number of Note Shares
into which the  Principal  so  converted  have been  converted.  The issuance of
certificates for Note Shares upon conversion of the Principal in accordance with
this Section 7 shall be made  without  charge to the Holder for any issuance tax
in respect thereof, if any.

                (f)     CONVERSION PRICE ADJUSTMENTS.  At any time and from time
to time while this Note is outstanding,  the Conversion Price shall be deemed to
be adjusted in accordance  with Section 4 of the  Certificate of Designations on
the same basis as if such  Certificate of Designations  had been duly authorized
and filed and had become  effective  and the Note  Shares had been issued on the
date hereof and the Conversion  Price,  so adjusted,  shall become the effective
Conversion  Price upon the  conversion of this Note and the issuance of the Note
Shares to the Holder.

        8.      NO WAIVERS BY DELAY OR PARTIAL EXERCISE.  No delay by the Holder
in exercising any powers or rights  hereunder  shall operate as a waiver of such
power or right,  nor shall any single or partial  exercise of any power or right
preclude other or further exercise  thereof,  or the exercise of any other power
or right hereunder or otherwise.
