2

--------------------------------------------------------------------------------

                        TO CONVERT MAY NOT BE EXERCISED FOR THE SIX (6) MONTH
PERIOD (THE “NON-CONVERSION PERIOD”) FOLLOWING THE DATE ON WHICH THE BORROWER
FILES A REGISTRATION STATEMENT WITH THE SECURITIES AND EXCHANGE COMMISSION FOR
THE PURPOSE OF REGISTERING SHARES TO BE OFFERED BY THE BORROWER IN A RIGHTS
OFFERING TO ITS STOCKHOLDERS, SO LONG AS AT ALL TIMES DURING THE NON-CONVERSION
PERIOD, THE BORROWER IS TAKING ALL REASONABLE STEPS TO EFFECTUATE THE
CONSUMMATION OF THE RIGHTS OFFERING.  THE NUMBER OF SHARES OF COMMON STOCK INTO
WHICH THIS NOTE MAY BE CONVERTED (THE “CONVERSION SHARES”) SHALL BE DETERMINED
BY DIVIDING THE CONVERSION PRINCIPAL (AS DETERMINED ON THE DATE THAT HOLDER
EXERCISES THIS CONVERSION RIGHT) BY THE CONVERSION PRICE.  THE INITIAL
CONVERSION PRICE SHALL BE $7.50.

II.               HOLDER SHALL BE ENTITLED TO CONVERT THIS NOTE BY SURRENDERING
THIS NOTE AT THE OFFICE OF THE BORROWER AND SHALL GIVE WRITTEN NOTICE TO THE

SHALL BE ENTITLED AS AFORESAID.  SUCH CONVERSION SHALL BE DEEMED TO HAVE BEEN
MADE IMMEDIATELY PRIOR TO THE CLOSE OF BUSINESS ON THE DATE OF SURRENDER OF THIS
NOTE, AND THE PERSON OR PERSONS ENTITLED TO RECEIVE THE CONVERSION SHARES
ISSUABLE UPON SUCH CONVERSION SHALL BE TREATED FOR ALL PURPOSES AS THE RECORD
HOLDER OR HOLDERS OF SUCH CONVERSION SHARES AS OF SUCH DATE.

IV.           NO FRACTIONAL SHARES OF COMMON STOCK SHALL BE ISSUED ON CONVERSION
OF THIS NOTE.

V.              IN THE EVENT THE BORROWER SHOULD AT ANY TIME OR FROM TIME TO
TIME AFTER THE DATE HEREOF FIX A RECORD DATE FOR THE SPLIT OR SUBDIVISION OF THE
OUTSTANDING SHARES OF COMMON STOCK OR THE DETERMINATION OF HOLDERS OF COMMON
STOCK TO RECEIVE DIVIDENDS OR OTHER DISTRIBUTIONS PAYABLE IN ADDITIONAL SHARES
OF COMMON STOCK OR OTHER SECURITIES OR RIGHTS CONVERTIBLE INTO, OR ENTITLING THE
HOLDER THEREOF TO RECEIVE DIRECTLY OR INDIRECTLY, ADDITIONAL SHARES OF COMMON
STOCK (“COMMON STOCK EQUIVALENTS”) WITHOUT PAYMENT OF ANY CONSIDERATION BY SUCH
HOLDER FOR THE ADDITIONAL SHARES OF COMMON STOCK OR THE COMMON STOCK
EQUIVALENTS, THEN, AS OF SUCH RECORD DATE (OR THE DATE OF SUCH DIVIDEND
DISTRIBUTION, SPLIT OR SUBDIVISION IF NO RECORD DATE IS FIXED), THE CONVERSION
PRICE OF THIS NOTE SHALL BE APPROPRIATELY DECREASED SO THAT THE NUMBER OF
CONVERSION SHARES ISSUABLE UPON CONVERSION OF THIS NOTE SHALL BE INCREASED IN
PROPORTION TO SUCH INCREASE OR POTENTIAL INCREASE OF OUTSTANDING SHARES OF
COMMON STOCK.

VI.           IF THE NUMBER OF SHARES OF COMMON STOCK OUTSTANDING AT ANY TIME
AFTER THE DATE HEREOF IS DECREASED BY A COMBINATION OF THE OUTSTANDING SHARES OF
COMMON STOCK, THEN, FOLLOWING THE RECORD DATE OF SUCH COMBINATION, THE
CONVERSION PRICE FOR THIS NOTE SHALL BE APPROPRIATELY INCREASED SO THAT THE
NUMBER OF SHARES OF COMMON

 

3

--------------------------------------------------------------------------------

                        STOCK ISSUABLE ON CONVERSION HEREOF SHALL BE DECREASED
IN PROPORTION TO SUCH DECREASE IN OUTSTANDING SHARES OF COMMON STOCK.

VII.        THE BORROWER SHALL AT ALL TIMES RESERVE AND KEEP AVAILABLE OUT OF
ITS AUTHORIZED BUT UNISSUED SHARES OF COMMON STOCK, SOLELY FOR THE PURPOSE OF
EFFECTING THE CONVERSION OF THIS NOTE, SUCH NUMBER OF ITS SHARES OF COMMON STOCK
AS SHALL FROM TIME TO TIME BE SUFFICIENT TO EFFECT THE CONVERSION OF THIS NOTE;
AND IF AT ANY TIME THE NUMBER OF AUTHORIZED BUT UNISSUED SHARES OF COMMON STOCK
SHALL NOT BE SUFFICIENT TO EFFECT THE CONVERSION OF THE ENTIRE CURRENT
CONVERSION PRINCIPAL OF THIS NOTE, IN ADDITION TO SUCH OTHER REMEDIES AS SHALL
BE AVAILABLE TO HOLDER, THE BORROWER WILL USE ITS BEST EFFORTS TO TAKE SUCH
CORPORATE ACTION AS MAY, IN THE OPINION OF ITS COUNSEL, BE NECESSARY TO INCREASE
ITS AUTHORIZED BUT UNISSUED SHARES OF COMMON STOCK TO SUCH NUMBER OF SHARES AS
SHALL BE SUFFICIENT FOR SUCH PURPOSES.

VIII.     THE BORROWER SHALL USE ITS BEST EFFORTS TO ENSURE THAT ANY FUTURE
ACQUISITIONS OF COMMON STOCK BY HOLDER UPON THE CONVERSION, IN WHOLE OR IN PART,
OF THE OUTSTANDING PRINCIPAL BALANCE OF THIS NOTE SHALL NOT BE SUBJECT TO THE
PROVISIONS OF ANY ANTI-TAKEOVER LAWS AND REGULATIONS OF ANY GOVERNMENTAL
AUTHORITY, INCLUDING WITHOUT LIMITATION, THE APPLICABLE PROVISIONS OF THE NEVADA
REVISED STATUTES, AND ANY PROVISIONS OF AN ANTI-TAKEOVER NATURE ADOPTED BY THE
BORROWER OR ANY OF ITS SUBSIDIARIES OR CONTAINED IN THE BORROWER’S ARTICLES OF
INCORPORATION, BYLAWS, OR THE ORGANIZATIONAL DOCUMENTS OF ANY OF ITS
SUBSIDIARIES, EACH AS AMENDED.

7.                                       NO SECURITY.  THIS NOTE IS AN UNSECURED
OBLIGATION OF THE BORROWER AND NO COLLATERAL ACCOMPANIES THE OBLIGATIONS
HEREUNDER.

INTEREST.  FURTHER, THE NOTES AND ANY NOTES SUBSEQUENTLY ISSUED IN REPLACEMENT

PRESENT AND FUTURE INDEBTEDNESS FOR MONEY BORROWED OF THE BORROWER OTHER THAN
THE SENIOR INDEBTEDNESS.

ACTS, EVENTS OR CIRCUMSTANCES SHALL CONSTITUTE AN EVENT OF DEFAULT (EACH AN

14.                                 SEVERABILITY; INVALIDITY.  THE BORROWER AND
HOLDER INTEND AND BELIEVE THAT EACH PROVISION IN THIS NOTE COMPORTS WITH ALL
APPLICABLE LOCAL, STATE AND FEDERAL LAWS AND JUDICIAL DECISIONS.  HOWEVER, IF
ANY PROVISIONS, PROVISION, OR PORTION OF ANY PROVISION IN THIS NOTE IS FOUND BY
A COURT OF COMPETENT JURISDICTION TO BE IN VIOLATION OF ANY APPLICABLE LOCAL,
STATE OR FEDERAL ORDINANCE, STATUTE, LAW, OR ADMINISTRATIVE OR JUDICIAL
DECISION, OR PUBLIC POLICY, AND IF SUCH COURT WOULD DECLARE SUCH PORTION,
PROVISION OR PROVISIONS OF THIS NOTE TO BE ILLEGAL, INVALID, UNLAWFUL, VOID OR
UNENFORCEABLE AS WRITTEN, THEN IT IS THE INTENT OF ALL PARTIES HERETO THAT SUCH
PORTION, PROVISION OR PROVISIONS SHALL BE GIVEN FORCE AND EFFECT TO THE FULLEST
POSSIBLE EXTENT THEY ARE LEGAL, VALID AND ENFORCEABLE, AND THE REMAINDER OF THIS
NOTE SHALL BE CONSTRUED AS IF SUCH ILLEGAL, INVALID, UNLAWFUL, VOID OR

TRANSCENDING THE LIMIT OF VALIDITY PRESCRIBED BY LAW WHICH A COURT OF COMPETENT

CIRCUMSTANCES THE HOLDER HEREOF SHALL EVER RECEIVE AS INTEREST AN AMOUNT WHICH
WOULD EXCEED THE HIGHEST LAWFUL RATE, SUCH AMOUNT WHICH WOULD BE EXCESSIVE
INTEREST SHALL BE APPLIED TO REDUCTION OF THE UNPAID PRINCIPAL BALANCE DUE
HEREUNDER AND NOT TO THE PAYMENT OF INTEREST.
