 CALYPTE BIOMEDICAL CORPORATION 
 10% UNSECURED CONVERTIBLE DEBENTURE 
 DUE JANUARY 14, 2004 
  

THIS DEBENTURE is issued by Calypte Biomedical Corporation., a Delaware Corporation, with its principal place of business at 1265 Harbor Bay Parkway, Alameda, CA 94502 (the
“Company”), designated as its 10% Unsecured Convertible Debenture, due January 14, 2004, in the aggregate principal amount of One Million Dollars ($1,000,000) (the “Debenture”). 
  
 FOR VALUE RECEIVED, the Company promises to pay to MERCATOR FOCUS FUND, L.P. or its registered assigns (the “Holder”), the principal sum of $1,000,000,
on January 14, 2004 or such earlier date as the Debenture is required or permitted to be repaid as provided hereunder (the “Maturity Date”) and to pay interest to the Holder on the aggregate unconverted and then outstanding principal
amount of this Debenture at the rate of 10% per annum, with interest accruing commencing on January 14, 2003 and payable on the first business day of each month while the Debenture remains outstanding (each an “Interest Payment
Date’”). Subject to the terms and conditions herein, the Holder may elect to receive interest hereunder in shares of Common Stock or cash. If interest is paid by the Company in shares of its Common Stock, then the number of shares of
Common Stock issuable on account of such interest shall equal the cash amount of such interest on such Interest Payment Date divided by the Conversion Price (as defined below) on such date. Interest shall be calculated on the basis on a 360-day year
and shall accrue daily commencing on the Original Issue Date (as defined in Section 5) until payment in full of the principal sum, together with all accrued and unpaid interest and other amounts, which may become due hereunder, has been made.
Interest hereunder will be paid to the Person (as defined in Section 5) in whose name this Debenture is registered on the records of the Company regarding registration and transfers of Debentures (the “Debenture Register”). All overdue








 accrued and unpaid interest to be paid in cash hereunder shall entail a late fee at the rate of 18% per annum (“Late Fee”) (or such
lower maximum amount of interest permitted to be charged under applicable law) which will accrue daily, from the date such interest is due hereunder through and including the date of payment, payable in cash or, at the option of the Holder, in
shares of Common Stock. If such Late Fee is paid by the Company in shares of its Common Stock, then the number of shares of Common Stock issuable on account of such Late Fee shall equal the cash amount of such Late Fee on such Late Fee payment date
divided by the Conversion Price on such date. 
  
 This Debenture is subject to the following additional provisions:

  
 Section 1. This Debenture is exchangeable for an equal aggregate principal amount of Debentures 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. 
  
 Section 2. This Debenture has been issued subject to certain investment representations of the original Holder set forth in the Purchase Agreement (as defined in
Section 5) and may be transferred or exchanged only in compliance with the Purchase Agreement. Prior to due presentment to the Company for transfer of this Debenture, the Company and any agent of the Company may treat the Person (as defined in
Section 5) 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) (i) Conversion at Option of Holder. 
  
 (A)
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, after the Original Issue Date (subject to the limitations on conversion set forth in Section 4(a)(ii)
hereof). The number of shares of Common Stock issuable upon a conversion hereunder equals the sum of (i) the quotient obtained by dividing (x) the outstanding principal amount of this Debenture to be converted by (y) the Conversion Price (see (c)(i)
of this Section 4), and (ii) the amount equal to (1) the product of (x) the outstanding principal amount of this Debenture to be converted and (y) the product of (1) the quotient obtained by dividing .10 by 360 and (2) the number of days for which
such principal amount was outstanding, divided by (II) the Conversion Price on the Conversion Date, provided, that if the Holder shall have elected to receive the interest due on a Conversion Date in cash, subsection (ii) shall not be used in the
calculation of the number of shares of Common Stock issuable upon a conversion hereunder. 
  
 (B) Notwithstanding anything to the contrary
contained herein, if on any Conversion Date: (1) the number of shares of Common Stock at the time authorized, unissued and unreserved for all purposes, or held as treasury stock, is insufficient to pay principal and interest hereunder in








 shares of Common Stock; (2) the Common Stock is not listed or quoted for trading on the OTC or on a Subsequent Market; (3) the Company has
failed to timely satisfy its conversion; or (4) the issuance of such shares of Common Stock would result in a violation of Section 4(a)(ii), then, at the option of the Holder, the Company, in lieu of delivering shares of Common Stock pursuant to
Section 4(a)(i), shall deliver, within three Trading Days of each applicable Conversion Date, an amount in cash equal to the product of the outstanding principal amount of the Debentures to be converted plus any interest due therein divided by the
Conversion Price and multiplied by the highest closing price of the stock from date of the conversion notice till the date that such cash payment is made. 
  
 (C) The Holder shall effect conversions by simultaneously delivering to the Company a completed notice in the form attached hereto as Exhibit A (a “Conversion Notice”), including a completed Conversion Schedule in
the form of Schedule I to the Conversion Notice (on each Conversion Date, the “Conversion Schedule”). The Conversion Schedule shall set forth the remaining principal amount of this Debenture and all accrued and unpaid interest thereon
subsequent to the conversion at issue. The date on which a Conversion Notice is delivered is the “Conversion Date.” Unless the Holder is converting the entire principal amount outstanding under this Debenture, the Holder is not be required
to physically surrender this Debenture to the Company in order to effect conversions. Subject to Section 4(b), each Conversion Notice, once given, shall be irrevocable. Conversions hereunder shall have the effect of lowering the outstanding
principal amount of this Debenture plus all accrued and unpaid interest thereon in an amount equal to the applicable conversion, which shall be evidenced by entries set forth in the Conversion Schedule. The Holder and the Company shall maintain
records showing the principal amount converted and the date of such conversions. In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of manifest error. 
  
 (ii) Certain Conversion Restrictions. 
  
 (A) A Holder may not convert the Debenture or receive shares of Common Stock as payment of interest hereunder to the extent such conversion or receipt of such interest payment would result in the Holder, together with any
affiliate thereof, beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of, and payment of interest on, the Debenture held by such Holder after application of this Section. Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of a
conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 9.999% of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the
limitation contained in this Section applies, the determination of which portion of the principal amount of the Debenture is convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for a
principal amount of the Debenture that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Company shall notify the Holder of this
fact and shall honor the conversion for the maximum principal amount permitted to be converted on such Conversion Date in accordance with the periods described in Section 4(b) and, at the option of the Holder, either retain any principal








 amount tendered for conversion in excess of the permitted amount hereunder for future conversions or return such excess principal amount to the
Holder. The provisions of this Section which limit issuance of Common Stock to Holder not exceeding 9.999% may only be waived by the mutual written consent of Company and Holder (but only as to Holder itself and not to any other Holder.)

  
 (b) (i) Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default
pursuant to Section 3 herein for the Company’s failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at
law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under
applicable law. Further, if the Company shall not have delivered any cash due in respect of conversion of the Debenture or as payment of interest thereon by the third Trading Day after the Conversion Date, the Holder may, by notice to the Company,
require the Company to issue shares of Common Stock pursuant to Section 4(c), except that for such purpose the Conversion Price applicable thereto shall be the lesser of the Conversion Price on the Conversion Date and the Conversion Price on the
date of such Holder demand. Any such shares will be subject to the provisions of this Section. 
  
 (ii) In addition to any other rights
available to the Holder, if the Company fails to deliver to the Holder such certificate or certificates pursuant to Section 4(b)(i) by the third Trading Day after the Conversion Date, and if after such third Trading Day the Holder purchases (in an
open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by such Holder of the Underlying Shares which the Holder anticipated receiving upon such conversion (a “Buy-In”), then the Company shall (A) pay in
cash to the Holder (in addition to any remedies available to or elected by the Holder) the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product
of (1) the aggregate number of shares of Common Stock that such Holder anticipated receiving from the conversion at issue multiplied by (2) the market price of the Common Stock at the time of the sale giving rise to such purchase obligation and (B)
at the option of the Holder, either reissue a Debenture in the principal amount equal to the principal amount of the attempted conversion or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company
timely complied with its delivery requirements under Section 4(b)(i). For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of Debentures with respect to
which the market price of the Underlying Shares on the date of conversion was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company
written notice indicating the amounts payable to the Holder in respect of the Buy-In. Notwithstanding anything contained herein to the contrary, if a Holder requires the Company to make payment in respect of a Buy-In for the failure to timely
deliver certificates hereunder and the Company timely pays in full such payment, the Company shall not be required to pay such Holder liquidated damages under Section 4(b)(ii) in respect of the certificates resulting in such Buy-In. 

 
 (c) (i) The conversion price (the “Conversion Price”) in effect on any Conversion Date shall be 80% of the average of
the lowest three inter-day trading prices (which need not occur on consecutive Trading Days) during the 20 Trading Days immediately preceding the 







 applicable Conversion Date (which may include Trading Days prior to the Original Issue Date), provided, that such 20 Trading Day period shall be
extended for the number of Trading Days during such period in which (A) trading in the Common Stock is suspended by, or not traded on, the OTC or a Subsequent Market on which the Common Stock is then listed, or (B) after the date, the Underlying
Shares Registration Statement is declared effective by the Commission, the Prospectus included in the Underlying Shares Registration Statement may not be used by the Holder for the resale of Underlying Shares. Furthermore, the Conversion Price in no
event shall be higher than $.10 (“the Ceiling). 
  
 (ii) If the Company, at any time while the Debenture is outstanding shall (a) 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, (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 Initial 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. 
  
 (iii) If the Company, at any time while the Debenture is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to the Holder) entitling them to subscribe for or purchase shares of Common Stock
at a price per share less than the Per Share Market Value at the record date mentioned below, then the Conversion Price shall be multiplied by a fraction, of which the denominator shall be the number of shares of the Common Stock (excluding treasury
shares, if any) outstanding on the date of issuance of such rights or warrants (plus the number of additional shares of Common Stock offered for subscription or purchase), and of which the numerator shall be the number of shares of the Common Stock
(excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants, plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such Per Share Market Value.
Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants. However, upon the
expiration of any such night, option or warrant to purchase shares of the Common Stock the issuance of which resulted in an adjustment in the Conversion Price pursuant to this Section, if any such right, option or warrant shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such expiration be recomputed and effective immediately upon such expiration be increased to the price which it would have been (but reflecting any other adjustments in the Conversion
Price made pursuant to the provisions of this Section after the issuance of such rights or warrants) had the adjustment of the Conversion Price made upon the issuance of such rights, options or warrants been made on the basis of offering for
subscription or purchase only that number of shares of the Common Stock actually purchased upon the exercise of such rights, options or warrants actually exercised. 
  
 (iv) If the Company or any subsidiary thereof, as applicable with respect to Common Stock Equivalents (as defined below), at any time while the Debenture is outstanding, shall issue shares








 of Common Stock or rights, warrants, options or other securities or debt that are convertible into or exchangeable for shares of Common Stock
(“Common Stock Equivalents”) entitling any Person to acquire shares of Common Stock, at a price per share less than the Conversion Price (if the holder of the Common Stock or Common Stock Equivalent 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 a 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, at the sole option of the Holder, the Conversion Price shall be adjusted to
mirror the conversion, exchange or purchase price for such Common Stock or Common Stock Equivalents (including any reset provisions thereof) at issue. Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued.
The Company shall notify the Holder and the Escrow Agent in writing, no later than the business day following the issuance of any Common Stock or Common Stock Equivalent subject to this section, indicating therein the applicable issuance price, or
of applicable reset price, exchange price, conversion price and other pricing terms. No adjustment under this Section shall be made as a result of issuances and exercises of options to purchase shares of Common Stock issued for compensatory purposes
pursuant to any of the Company’s stock option or stock purchase plans. 
  
 (v) If the Company, at any time while the Debenture is
outstanding, shall distribute to all holders of Common Stock (and not to the Holder) 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 at which the
Debenture shall thereafter be convertible shall be determined by multiplying the 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 Per Share Market Value determined as of the record date mentioned above, and of which the numerator shall be such Per Share Market Value 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
Holder 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. 
  
 (vi) In case of any reclassification of the Common Stock or any compulsory share
exchange pursuant to which the Common Stock is converted into other securities, cash or property, the Holder shall have the right thereafter to, at its option, (A) convert the then outstanding principal amount, together with all accrued but unpaid
interest and any other amounts then owing hereunder in respect of this Debenture only into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of the Common Stock following such
reclassification or share exchange, and the Holder of the Debenture shall be entitled upon such event to receive such amount of securities, cash or property as the shares of the Common Stock of the Company into which the then outstanding principal
amount, together with all accrued but unpaid interest and any other amounts then owing hereunder in respect of this Debenture could have been converted immediately prior to such reclassification or share exchange would have been entitled, or (B)
require the Company to prepay the outstanding principal amount of the 







 Debenture, plus all interest and other amounts due and payable thereon, at a price determined in accordance with Section 3(b). The entire
prepayment price shall be paid in cash. This provision shall similarly apply to successive reclassifications or share exchanges. 
  
 (vii)
The Company shall maintain a share reserve of not less than 200% of the shares of Common Stock issuable upon conversion of the Debenture; and within three Business Days following the receipt by the Company of a Holder’s notice that such minimum
number of Underlying Shares is not so reserved, the Company shall promptly reserve a sufficient number of shares of Common Stock to comply with such requirement. 
  
 (viii) All calculations under this Section 4 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. No adjustments in either the Conversion Price or the Initial Conversion Price shall be
required if such adjustment is less than $0.01, provided, however, that any adjustments which by reason of this Section are not required to be made shall be carried forward and taken into account in any subsequent adjustment. 

 
 (ix) Whenever either the Initial Conversion Price or the Conversion Price is adjusted pursuant to any of Section 4(c)(ii) - (v), the Company shall
promptly mail to the Holder a notice setting forth the Initial Conversion Price or Conversion Price (as applicable) after such adjustment and setting forth a brief statement of the facts requiring such adjustment. 
  
 (x) 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 dissolution, liquidation or winding up of the affairs of the
Company; then, in each case, the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of the Debenture, and shall cause to be mailed to the Holder at its last address as it shall appear upon the stock
books of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights
or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the
Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall
not affect the validity of the corporate action required to be specified in such notice. The Holder is entitled to convert the Debenture during the 20-day calendar period commencing the date of such notice to the effective date of the event
triggering such notice. 
  
 (xi) In case of any (1) merger or consolidation of the Company with or into another Person, or (2) sale by the
Company of more than one-half of the assets of the Company in one or a series of related transactions, a Holder shall have the right to (A) exercise any rights under Section 3(b), 







 (B) convert the aggregate principal amount of the Debenture then outstanding into the shares of stock and other securities, cash and property
receivable upon or deemed to be held by holders of Common Stock following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as
the shares of Common Stock into which such aggregate principal amount of the Debenture could have been converted immediately prior to such merger, consolidation or sales would have been entitled, or (C) in the case of a merger or consolidation,
require the surviving entity to issue to the Holder a convertible debenture with a principal amount equal to the aggregate principal amount of the Debenture then held by such Holder, plus all accrued and unpaid interest and other amounts owing
thereon, which such newly issued convertible debenture shall have terms identical (including with respect to conversion) to the terms of this Debenture, and shall be entitled to all of the rights and privileges of the Holder of the Debenture set
forth herein and the agreements pursuant to which the Debentures were issued. In the case of clause (C), the conversion price applicable for the newly issued shares of convertible preferred stock or convertible debentures shall be based upon the
amount of securities, cash and property that each share of Common Stock would receive in such transaction and the Conversion Price in effect immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger,
sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or redemption following such event. This provision shall
similarly apply to successive such events. 
  
 (d) 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 the Debenture and payment of interest on the Debenture, each as herein provided, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder, 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 set forth in the Debenture)
be issuable (taking into account the adjustments and restrictions of Section 4(b)) upon the conversion of the outstanding principal amount of the 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 and, if the Underlying Shares Registration Statement has been declared effective under the Securities Act, registered for public sale in

 Section 11. Any waiver by the Company or the Holder of a breach of any provision of this Debenture shall not operate as
or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture. The failure of the Company or the Holder to insist upon strict adherence to any term of this Debenture on one or more
occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Debenture. Any waiver must be in writing. 
  
 Section 12. If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in
effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder shall
violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest. The Company covenants (to the extent that it may lawfully do so) that it shall not
at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or
interest on the Debenture as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and the Company (to the extent it may lawfully do so) hereby expressly
waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impeded the execution of any power herein granted to the Holder, but will suffer and permit the execution of every such as
though no such law has been enacted.

be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

to the Security Agreement (as defined in the Purchase Agreement).

DEBENTURE shall be kept in complete confidence by the Holder, the Company, and each of the affiliates, directors, officers, employees and agents of the Company, and dissemination of the contents of this DEBENTURE or knowledge of its existence and
related information shall only be to those persons as absolutely necessary, or as 







 required by any governmental agencies, including the Commission, pursuant to the Registration of the Debenture.

 REGISTRATION RIGHTS AGREEMENT

  
 AGREEMENT dated as of the 14th day of January, 2003, between MERCATOR FOCUS FUND LP, a California limited partnership (the “Holder”), and CALYPTE BIOMEDICAL
CORPORATION, a Delaware corporation (the “Company”). 
  
 WHEREAS, the Holder has the right to cause
the 10% Unsecured Convertible Debenture (the “Debenture”) purchased by the Holder from the Company to be converted into shares of Common Stock, $.001 par value (the “Common Stock”) of the Company, pursuant to the conversion
formula set forth in the Debenture; and 
  
 WHEREAS, the Company desires to grant to the Holder the
registration rights set forth herein with respect to the shares of Common Stock issuable upon the conversion of the Debenture; 
  
 NOW, THEREFORE, the parties hereto mutually agree as follows: 
  
 1. Registrable
Securities. As used herein the term “Registrable Security” means each of the shares of Common Stock issued upon the conversion of the Debenture; provided, however, that with respect to any particular Registrable Security, such
security shall cease to be a Registrable Security when, as of the date of determination, (a) it has been effectively registered under the Securities Act of 1933, as amended (the “Securities Act”) and disposed of pursuant thereto, or (b)
registration under the Securities Act is no longer required for the immediate public distribution of such security. The term “Registrable Securities” means any and/or all of the securities falling within the foregoing definition of a
“Registrable Security.” In the event of any merger, reorganization, consolidation, recapitalization or other change in corporate structure affecting the Common Stock, such adjustment shall be made in the definition of “Registrable
Security” as is appropriate in order to prevent any dilution or enlargement of the rights granted pursuant to this Section 1. 
  
 2. Registration. The Company agrees to file a registration statement (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) within 60 days of the
Holder’s purchase of the Debenture in order to register the resale of the Registrable Securities under the Securities Act. Once effective, the Company will be required to maintain the effectiveness of the Registration Statement until the
earlier of (a) the date that all of the Registrable Securities have been sold, or (b) the date that the Company receives an opinion of counsel to the Company that all of the Registrable Securities may be freely traded without registration under the
Securities Act, under Rule 144 promulgated under the Securities Act or otherwise. 
  
 3. Covenants of the
Company With Respect to Registration. 
  
 The Company covenants and agrees as follows: 







  
 (a) The Company shall use its best efforts to cause the Registration Statement to
become effective as promptly as possible and, if any stop order shall be issued by the Commission in connection therewith, to use its best reasonable efforts to obtain the removal of such order. Following the effective date of the Registration
Statement, the Company shall, upon the request of the Holder, forthwith supply such reasonable number of copies of the Registration Statement, preliminary prospectus and prospectus meeting the requirements of the Securities Act, and other documents
necessary or incidental to the public offering of the Registrable Securities, as shall be reasonably requested by the Holder to permit the Holder to make a public distribution of the Holder’s Registrable Securities. The obligations of the
Company hereunder with respect to the Holder’s Registrable Securities are subject to the Holder’s furnishing to the Company such appropriate information concerning the Holder, the Holder’s Registrable Securities and the terms of the
Holder’s offering of such Registrable Securities as the Company may reasonably request in writing. 
  
 (b) The
Company shall pay all costs, fees and expenses in connection with the Registration Statement filed pursuant to Section 2 hereof including, without limitation, the Company’s legal and accounting fees, printing expenses, and blue sky fees and
expenses; provided, however, that the Holder shall be solely responsible for the fees of any counsel retained by the Holder in connection with such registration and any transfer taxes or underwriting discounts, commissions or fees applicable to the
Registrable Securities sold by the Holder pursuant thereto. 
  
 (c) The Company will take all necessary action which
may be required to qualify or register the Registrable Securities included in the Registration Statement for the offer and sale under the securities or blue sky laws of such states as are reasonably requested by the Holder of such securities,
provided that the Company shall not be obligated to execute or file any general consent to service of process or to qualify as a foreign corporation to do business under the laws of any such jurisdiction. 
  
 4. Additional Terms. 
  
 (a) The Company shall indemnify and hold harmless the Holder and each underwriter, within the meaning of the Securities Act, who may purchase from or sell for the Holder, any Registrable Securities,
from and against any and all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in the Registration Statement, any other registration statement filed by the Company under the Securities Act with
respect to the registration of the Registrable Securities, any post-effective amendment to such registration statements, or any prospectus included therein or caused by any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission based upon information furnished or required to be furnished in writing to the
Company by the Holder or underwriter expressly for use therein, which indemnification shall include each person, if any, who controls either the Holder or underwriter within the meaning of the Securities Act and each officer, director, employee and
agent of the Holder and underwriter; provided, however, that the indemnification in 







  
 this Section 4(a) with respect to any prospectus shall not inure to the benefit of the Holder or
underwriter (or to the benefit of any person controlling the Holder or underwriter) on account of any such loss, claim, damage or liability arising from the sale of Registrable Securities by the Holder or underwriter, if a copy of a subsequent
prospectus correcting the untrue statement or omission in such earlier prospectus was provided to the Holder or underwriter by the Company prior to the subject sale and the subsequent prospectus was not delivered or sent by the Holder or underwriter
to the purchaser prior to such sale and provided further, that the Company shall not be obligated to so indemnify the Holder or any such underwriter or other person referred to above unless the Holder or underwriter or other person, as the case may
be, shall at the same time indemnify the Company, its directors, each officer signing the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any and all losses, claims,
damages and liabilities caused by any untrue statement of a material fact contained in the Registration Statement, any registration statement or any prospectus required to be filed or furnished by reason of this Agreement or caused by any omission
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission based upon information
furnished in writing to the Company by the Holder or underwriter expressly for use therein. 
  
 (b) If for any reason
the indemnification provided for in the preceding section is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or expense referred to therein, then the indemnifying
party, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only
the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. 
  
 (c) Neither the filing of a Registration Statement by the Company pursuant to this Agreement nor the making of any request for
prospectuses by the Holder shall impose upon the Holder any obligation to sell the Holder’s Registrable Securities. 
  
 (d) The Holder, upon receipt of notice from the Company that an event has occurred which requires a Post-Effective Amendment to the Registration Statement or a supplement to the prospectus included therein, shall promptly discontinue
the sale of Registrable Securities until the Holder receives a copy of a supplemented or amended prospectus from the Company, which the Company shall provide as soon as practicable after such notice. 
  
 (e) If the Company fails to keep the Registration Statement referred to above continuously effective during the requisite period, then the
Company shall, promptly upon the request of the Holder, use its best efforts to update the Registration Statement or file a new registration statement covering the Registrable Securities remaining unsold, subject to the terms and provisions hereof.








  
 (f) The Holder agrees to provide the Company with any information or undertakings
reasonably requested by the Company in order for the Company to include any appropriate information concerning the Holder in the Registration Statement or in order to promote compliance by the Company or the Holder with the Securities Act.

  
 5. Governing Law. The Registrable Securities will be, if and when issued, delivered in California.
This Agreement shall be deemed to have been made and delivered in the State of California and shall be governed as to validity, interpretation, construction, effect and in all other respects by the internal substantive laws of the State of
California, without giving effect to the choice of law rules thereof. 
  
 6. Amendment. This Agreement
may only be amended by a written instrument executed by the Company and the Holder. 
  
 7. Entire
Agreement. This Agreement constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject
matter hereof. 
  
 8. Execution in Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same document.
