Section 2.        Interest.

this Debenture at the rate of 2.5% per annum, payable on the earlier of the

Payment Date"), in cash or shares of Common Stock at the Interest Conversion

Conversion Shares within the time period required by Section 4(d)(ii). Interest
hereunder will be paid to the Person in whose name this Debenture is registered

which will accrue daily, from the date such interest is due hereunder through
and including the date of payment.

     d) Prepayment. Except as otherwise set forth in this Debenture, the Company
may not prepay any portion of the principal amount of this Debenture without the
prior written consent of the Holder.

Section 3.      Registration of Transfers and Exchanges.
----------      ----------------------------------------

     a) Different Denominations. This Debenture is exchangeable for an equal
aggregate principal amount of Debenture of different authorized denominations,
as requested by the Holder surrendering the same. No service charge will be made
for such registration of transfer or exchange.

     b) Investment Representations. This Debenture has been issued subject to
certain investment representations of the original Holder set forth in the
Purchase and Sale Agreement and may be transferred or exchanged only in
compliance with the Purchase and Sale Agreement and applicable federal and state
securities laws and regulations.

     c) Reliance on Debenture Register. Prior to due presentment to the Company
for transfer of this Debenture, the Company and any agent of the Company may
treat the Person in whose name this Debenture is duly registered on the
Debenture Register as the owner hereof for the purpose of receiving payment as
herein provided and for all other purposes, whether or not this Debenture is
overdue, and neither the Company nor any such agent shall be affected by notice
to the contrary.

Section 4.          Conversion.
----------          ----------

     a) Voluntary Conversion. At any time after the Original Issue Date until
this Debenture is no longer outstanding, this Debenture shall be convertible
into shares of Common Stock, at the option of the Holder, in whole or in part at
any time and from time to time. The Holder shall effect conversions by
delivering to the Company the form of Notice of Conversion attached hereto as
Annex A (a "Notice of Conversion"), specifying therein the principal amount of
this Debenture to be converted and the date on which such conversion is to be
effected (a "Conversion Date"). If no Conversion Date is specified in a Notice
of Conversion, the Conversion Date shall be the date that such Notice of
Conversion is provided hereunder. However, the Conversion Date shall not be a
date that is earlier than the date of receipt of the Notice of Conversion by the
Company. To effect conversions hereunder, the Holder shall not be required to
physically surrender this Debenture to the Company unless the entire principal
amount of this Debenture plus all accrued and unpaid interest thereon has been
so converted. Conversions hereunder shall have the effect of lowering the
outstanding principal amount of this Debenture in an amount equal to the
applicable conversion. The Holder and the Company shall maintain records showing
the principal and/or accrued interest amounts converted and the date of such
conversions. The Company shall deliver any objection to any Notice of Conversion
within 1 Business Day of receipt of such notice. In the event of any dispute or
discrepancy, the records of the Company shall be controlling and determinative
in the absence of manifest error. The Holder and any assignee, by acceptance of
this Debenture, acknowledge and agree that, by reason of the provisions of this
paragraph, following conversion of a portion of this Debenture, the unpaid and
unconverted principal amount of this Debenture may be less than the amount
stated on the face hereof.


                                       4
<PAGE>
     b) Conversion Price. The conversion price in effect on any Conversion Date
shall be equal to $2.00 (subject to adjustment herein)(the "Conversion Price").

     c) Intentionally omitted.

     d) Mechanics of Conversion

          i. Conversion Shares Issuable Upon Conversion. The number of shares of
     Common Stock issuable upon a conversion hereunder shall be determined by
     the quotient obtained by dividing (x) the outstanding principal amount of
     this Debenture to be converted by (y) the Conversion Price.

          ii. Delivery of Certificate Upon Conversion. Not later than five (5)
     Trading Days after any Conversion Date (the "Share Delivery Date"), the
     Company will deliver to the Holder (A) a certificate or certificates
     representing the Conversion Shares representing the number of shares of
     Common Stock being acquired upon the conversion of Debenture (including, if
     so elected by the Company, shares of Common Stock representing payment of
     accrued interest) and (B) a check in the amount of accrued and unpaid
     interest (if the Company has elected to pay accrued interest in cash).

          iii. Reservation of Shares Issuable Upon Conversion. The Company
     covenants that it will at all times reserve and keep available out of its
     authorized and unissued shares of Common Stock solely for the purpose of
     issuance upon conversion of this Debenture and payment of interest on this
     Debenture, each as herein provided, free from preemptive rights or any
     other actual contingent purchase rights of persons other than the Holders,
     not less than such number of shares of the Common Stock as shall (subject
     to any additional requirements of the Company as to reservation of such
     shares) be issuable (taking into account the adjustments and restrictions
     of Section 5) upon the conversion of the outstanding principal amount of
     this Debenture and payment of interest hereunder. The Company covenants
     that all shares of Common Stock that shall be so issuable shall, upon
     issue, be duly and validly authorized, issued and fully paid,
     nonassessable.

          iv. Fractional Shares. Upon a conversion hereunder, in the event the
     conversion yields a fractional share, the Holder shall be entitled to
     receive, in lieu of the final fraction of a share, one whole share of
     Common Stock.

          v. Transfer Taxes. The issuance of certificates for shares of the
     Common Stock on conversion of this Debenture shall be made without charge
     to the Holders thereof for any documentary stamp or similar taxes that may
     be payable in respect of the issue or delivery of such certificate,
     provided that the Company shall not be required to pay any tax that may be
     payable in respect of any transfer involved in the issuance and delivery of
     any such certificate upon conversion in a name other than that of the
     Holder of such Debenture so converted and the Company shall not be required
     to issue or deliver such certificates unless or until the person or persons
     requesting the issuance thereof shall have paid to the Company the amount
     of such tax or shall have established to the satisfaction of the Company
     that such tax has been paid.


Section 5.        Certain Adjustments.
----------        --------------------

     a) Stock Dividends and Stock Splits. If the Company, at any time while this
Debenture is outstanding: (A) shall pay a stock dividend or otherwise make a
distribution or distributions on shares of its Common Stock or any other equity
or equity equivalent securities payable in shares of Common Stock (which, for
avoidance of doubt, shall not include any shares of Common Stock issued by the
Company pursuant to this Debenture, the Company's outstanding 2.5% Convertible
Debentures due July 22, 2007, the Company's Series A 18% Cumulative Convertible
Preferred Stock or the Company's Series B 12% Cumulative Convertible Preferred
Stock, including as interest thereon), (B) subdivide outstanding shares of
Common Stock into a larger number of shares, (C) combine (including by way of
reverse stock split) outstanding shares of Common Stock into a smaller number of
shares, or (D) issue by reclassification of shares of the Common Stock any
shares of capital stock of the Company, then the Conversion Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding before such event
and of which the denominator shall be the number of shares of Common Stock
outstanding after such event. Any adjustment made pursuant to this Section shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination or re-classification.


                                       5
<PAGE>
     b) Subsequent Equity Sales. If the Company at any time while this Debenture
is outstanding, shall offer, sell, grant any option to purchase or offer, sell
or grant any right to reprice its securities, or otherwise dispose of or issue
(or announce any offer, sale, grant or any option to purchase or other
disposition) any Common Stock or Common Stock Equivalents entitling any Person
to acquire shares of Common Stock, at an effective price per share less than the
then Conversion Price (such lower price, the "Base Conversion Price" and such
issuances collectively, a "Dilutive Issuance"), as adjusted hereunder (if the
holder of the Common Stock or Common Stock Equivalents so issued shall at any
time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to
warrants, options or rights per share which is issued in connection with such
issuance, be entitled to receive shares of Common Stock at an effective price
per share which is less than the Conversion Price, such issuance shall be deemed
to have occurred for less than the Conversion Price), then the Conversion Price
shall immediately (except in the case of an Exempt Issuance) be reduced to the
price determined by dividing (1) an amount equal to the sum of (A) the number of
shares of Common Stock outstanding immediately prior to such issuance multiplied
by the Conversion Price in effect immediately prior to such issuance and (B) the
consideration, if any, received by the Corporation upon such issuance, by (2)
the total number of shares of Common Stock outstanding immediately after such
issuance. Such adjustment shall be made whenever such Common Stock or Common
Stock Equivalents are issued. The Company shall notify the Holder in writing, no
later than the Business Day following the issuance of any Common Stock or Common
Stock Equivalents subject to this section, indicating therein the applicable
issuance price, or of applicable reset price, exchange price, conversion price
and other pricing terms (such notice the "Dilutive Issuance Notice"). For
purposes of clarification, whether or not the Company provides a Dilutive
Issuance Notice pursuant to this Section 5(b), upon the occurrence of any
Dilutive Issuance, after the date of such Dilutive Issuance the Holder is
entitled to receive a number of Conversion Shares based upon the Base Conversion
Price regardless of whether the Holder accurately refers to the Base Conversion
Price in the Notice of Conversion.

     c) Pro Rata Distributions. If the Company, at any time while this Debenture
is outstanding, shall distribute to all holders of Common Stock (and not to
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Conversion
Price shall be determined by multiplying such Conversion Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the VWAP determined as of the record date mentioned above, and of which
the numerator shall be such VWAP on such record date less the then fair market
value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holders of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.


                                       6
<PAGE>
     d) Fundamental Transaction. If, at any time while this Debenture is
outstanding, (A) the Company effects any merger or consolidation of the Company
with or into another Person, (B) the Company effects any sale of all or
substantially all of its assets in one or a series of related transactions, (C)
any tender offer or exchange offer (whether by the Company or another Person) is
completed pursuant to which holders of Common Stock are permitted to tender or
exchange their shares for other securities, cash or property, or (D) the Company
effects any reclassification of the Common Stock or any compulsory share
exchange pursuant to which the Common Stock is effectively converted into or
exchanged for other securities, cash or property (in any such case, a
"Fundamental Transaction"), then upon any subsequent conversion of this
Debenture, the Holder shall have the right to receive, for each Conversion Share
that would have been issuable upon such conversion absent such Fundamental
Transaction, the same kind and amount of securities, cash or property as it
would have been entitled to receive upon the occurrence of such Fundamental
Transaction if it had been, immediately prior to such Fundamental Transaction,
the holder of one share of Common Stock (the "Alternate Consideration"). For
purposes of any such conversion, the determination of the Conversion Price shall
be appropriately adjusted to apply to such Alternate Consideration based on the
amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the
Conversion Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate
Consideration. If holders of Common Stock are given any choice as to the
securities, cash or property to be received in a Fundamental Transaction, then
the Holder shall be given the same choice as to the Alternate Consideration it
receives upon any conversion of this Debenture following such Fundamental
Transaction. To the extent necessary to effectuate the foregoing provisions, any
successor to the Company or surviving entity in such Fundamental Transaction
shall issue to the Holder a new debenture consistent with the foregoing
provisions and evidencing the Holder's right to convert such debenture into
Alternate Consideration. The terms of any agreement pursuant to which a
Fundamental Transaction is effected shall include terms requiring any such
successor or surviving entity to comply with the provisions of this paragraph
(c) and insuring that this Debenture (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental
Transaction.

     e) Calculations. All calculations under this Section 5 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be. For purposes
of this Section 5, the number of shares of Common Stock deemed to be issued and
outstanding as of a given date shall be the sum of the number of shares of
Common Stock (excluding treasury shares, if any) issued and outstanding.

     f) Exempt Issuance. Notwithstanding the foregoing, no adjustment will be
made under this Section 5 in respect of an Exempt Issuance.

     g) Notice to Holders.

          i. Adjustment to Conversion Price. Whenever the Conversion Price is
     adjusted pursuant to any of this Section 5, the Company shall promptly mail
     to each Holder a notice setting forth the Conversion Price after such
     adjustment and setting forth a brief statement of the facts requiring such
     adjustment. If the Company issues a variable rate security in a Variable
     Rate Transaction (as defined in the Subscription Agreement), despite the
     prohibition thereon in the Subscription Agreement, the Company shall be
     deemed to have issued Common Stock or Common Stock Equivalents at the
     lowest possible conversion or exercise price at which such securities may
     be converted or exercised.


                                       7
<PAGE>
          ii. Notice to Allow Conversion by Holder. If (A) the Company shall
     declare a dividend (or any other distribution) on the Common Stock; (B) the
     Company shall declare a special nonrecurring cash dividend on or a
     redemption of the Common Stock; (C) the Company shall authorize the
     granting to all holders of the Common Stock rights or warrants to subscribe
     for or purchase any shares of capital stock of any class or of any rights;
     (D) the approval of any stockholders of the Company shall be required in
     connection with any reclassification of the Common Stock, any consolidation
     or merger to which the Company is a party, any sale or transfer of all or
     substantially all of the assets of the Company, of any compulsory share
     exchange whereby the Common Stock is converted into other securities, cash
     or property; (E) the Company shall authorize the voluntary or involuntary

Section 8.        Subordination.
----------        --------------

     (a) Agreement to Subordinate. The Company agrees, and the Holder agrees by
accepting the Debenture that the indebtedness evidenced by this Debenture is
subordinated in right of payment, to the extent and in the manner provided in
this Section 8, to the prior payment in full of the Company's 2.5% Convertible
Debentures due July 22, 2007. This agreement to subordinate is for the benefit
of the holders of the 2.5% Convertible Debentures due July 22, 2007. The
provisions of this Section 8 shall be null and void upon full payment of the
2.5% Convertible Debentures due July 22, 2007.

     (b) Liquidation; Dissolution; Bankruptcy. Upon any distribution to
creditors of the Company in a liquidation or dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or any of its properties, in an assignment for the
benefit of creditors or any marshaling of the Company's assets and liabilities,
the holders of the 2.5% Convertible Debentures due July 22, 2007 shall be
entitled to receive payment in full of all obligations due in respect of such
2.5% Convertible Debentures due July 22, 2007 (including interest after the
commencement of any such proceeding at the rate specified in the 2.5%
Convertible Debentures due July 22, 2007, whether or not allowable as a claim in
such proceeding) before the Holder of this Debenture shall be entitled to
receive any payment with respect to the Debenture.

     (c) Change; Extension of Time; Renewal, or Alteration. The holders of the
2.5% Convertible Debentures due July 22, 2007 may, at any time and from time to
time, without the consent of or notice to the Holder of this Debenture, without
incurring responsibility to the Holder of this Debenture and without impairing
or releasing the obligations of the Holder of this Debenture to the holders of
the 2.5% Convertible Debentures due July 22, 2007, change or extend the time of
payment of, or renew or alter, any of the 2.5% Convertible Debentures due July
22, 2007, or otherwise amend in any manner any agreement pursuant to which the
2.5% Convertible Debentures due July 22, 2007 shall have been issued and
exercise or refrain from exercising any rights against the Company and any other
person.

     (e) Failure to Act. No holder of the 2.5% Convertible Debentures due July
22, 2007 shall be prejudiced in its right to enforce subordination of this
Debenture by any act or failure to act by the Company or any other person in the
custody of the assets or property of the Company.

     (f) Purpose. The provisions of this Section 8 regarding subordination are
solely for the purpose of defining the relative rights of the holders of the
2.5% Convertible Debentures due July 22, 2007 on the one hand and the rights of
the Holder of this Debenture on the other hand, and none of such provisions
shall impair, as between the Company and the Holder of this Debenture, the
obligation of the Company, which is unconditional and absolute, to pay to the
Holder of this Debenture the principal of and interest on this Debenture in
accordance with the terms of this Debenture, and no such provisions shall
prevent the Holder of this Debenture from exercising the remedies permitted by
applicable law in accordance with the provisions of this Note.
