Price on the date of such event, then the Conversion Price in effect immediately
prior thereto shall be adjusted as provided below so that the Conversion Price
therefor shall be equal to the price determined by multiplying (A) the
Conversion Price at which shares of Series A Preferred Stock were theretofore
convertible by (B) a fraction of which (x) the denominator shall be the Current
Market Price per share on the date of such event, and (y) the numerator shall be
the Current Market Price per share on the date of such event less the difference
between (1) the consideration paid by the Corporation per share of Common Stock
(or, in the case of securities convertible into or exchangeable for Common
Stock, the consideration per share of Common Stock into which such security is
convertible or exchangeable) purchased, redeemed or acquired in such event and
(2) the Current Market Price per share on the date of such event. Such
adjustment shall be made whenever such Common Stock is issued or sold, and shall
become effective immediately after the issuance or sale of such securities. The
foregoing notwithstanding, no adjustment shall be made pursuant to this
subparagraph (iv) with respect to any particular purchase, redemption or
acquisition with respect to which a Payout Election is made."

security is convertible or exchangeable greater than the per share Current
Market Price on the date of such event, then the Conversion Price in effect
immediately prior thereto shall be adjusted as provided below so that the
Conversion Price therefor shall be equal to the price determined by multiplying
(A) the Conversion Price at which shares of Series B Preferred Stock were
theretofore convertible by (B) a fraction of which (x) the denominator shall be
the Current Market Price per share on the date of such event, and (y) the
numerator shall be the Current Market Price per share on the date of such event
less the difference between (1) the consideration paid by the Corporation per
share of Common Stock (or, in the case of securities convertible into or
exchangeable for Common Stock, the consideration per share of Common Stock into
which such security is convertible or exchangeable) purchased, redeemed or
acquired in such event and (2) the Current Market Price per share on the date of

Purchase Agreement shall remain in full force and effect, and the execution of
this Amendment is not a waiver by the Company or the Purchasers of any of the
terms or provisions of the Stock Purchase Agreement.
