The following is a summary of the terms of the transactions contemplated by the Amendment Agreement. This summary is not intended to be complete and is qualified in its entirety by reference to the attachments to this Supplemental Disclosure.
 
1. Amendment Agreement
 
pSivida Limited (“pSivida”) and an institutional investor (the “Investor”) entered into an Amendment Agreement dated as of July 28, 2006, providing for the exchange of the Subordinated Convertible Note, dated November 16, 2005, purchased in connection with the Securities Purchase Agreement, dated October 5, 2005, by and between the same parties, for an Amended and Restated Subordinated Convertible Note and warrants.
 
Under the Amendment Agreement, pSivida will exchange with the Investor its original Subordinated Convertible Note for an Amended and Restated Convertible Note in the amount of $12.5 million that is secured by certain royalty payments and a warrant exercisable for up to 5,700,000 American Depositary Shares (ADSs) of pSivida and will pay the Investor $3.5 million in partial satisfaction and redemption of the original Subordinated Convertible Note, any accrued and unpaid interest on the Subordinated Convertible Note, and any penalties incurred as a result of the delay in effectiveness of the registration statement filed in connection with the Securities Purchase Agreement.
 
The Amendment Agreement was furnished on pSivida’s Form 6-K filed on July 31, 2006. The Amendment Agreement contains representations and warranties that pSivida and the Investor made to each other as of the date of the Amendment Agreement or other specific dates, and such representations and warranties should not be relied upon by any other person.
 
2. Amended and Restated Convertible Note
 
The following is a summary of the terms of the note:
 
·  
The note has a face value of US$12,500,000.
 

 
·  
The note may be converted by the holder into ADSs at any time prior to the third anniversary of the date of the original issuance of the note. The number of shares to be issued upon conversion of the note is to be calculated by dividing the face value of the note to be converted (and any accrued but unpaid interest on the note) by the conversion price, as adjusted, of the ADSs.
 
·  
The conversion price is US$2.00 per ADS and may be adjusted under certain circumstances, including, among others, in the event pSivida issues securities at a lower price than the price at which the note may be converted and based on the market price of pSivida’s ADSs on April 30, 2007.
 
·  
The note matures on November 16, 2008 and bears interest at the rate of 8% per annum.
 
·  
Under certain circumstances, pSivida may make interest payments in the form of ADSs.
 
·  
The note contains certain events of default which allow the Investor to accelerate the maturity of the note and permit the Investor to force payment of the note in the event of a change of control of pSivida.
 
·  
pSivida has the right, in certain specified circumstances, to force the Investor to convert the note into ADSs, including if the ADSs are trading at 200% of the conversion price during a specified period.
 
·  
The Investor has the right to require pSivida to prepay up to 50% of the original principal amount (i.e., $6,250,000) on July 31, 2007 and January 31, 2008.
 
·  
pSivida may redeem the note, at its option, in whole or in part at any time at a price equal to 108% of the outstanding principal to be redeemed. In connection with any such redemption, pSivida will issue warrants exercisable for a number of shares equal to 30% of such redemption amount divided by the then applicable conversion price.
 
·  
There is a limit of 4.99% in respect of the Investor and its affiliates’ beneficial ownership in pSivida, which may prevent it from converting part of the note (this limit may be increased or decreased by the Investor upon written notice to pSivida).
 
·  
The note contains various negative covenants, including limitations on the incurrence of debt and liens, and the maintenance of certain cash levels.
 
The Form of Amended and Restated Convertible Note was furnished on pSivida’s Form 6-K filed on July 31, 2006. The final version of the Amended and Restated Convertible Note is furnished on the Form 6-K to which this Supplemental Disclosure is also an Exhibit.
 
3. Guaranty, Collateral Assignment and Acknowledgment of Collateral Assignment
 
The following is a summary of the security interest granted by pSivida to the Investor:
 
·  
The indebtedness represented by the note will be secured by a first priority lien on the royalty payments received by pSivida Inc., pSivida’s wholly-owned U.S. subsidiary, from Bausch & Lomb Incorporated pursuant to a license agreement.
 
·  
In order to effect the security interest, pSivida Inc. entered into the Collateral Assignment assigning its rights under the license agreement to the Investor. pSivida Inc. also entered into a Guaranty obligating it to guarantee the obligations of pSivida under the Note.
 
·  
Bausch & Lomb Incorporated consented to the assignment of rights pursuant to the Collateral Assignment.
 
·  
The security interest shall be released upon pSivida’s satisfaction of the note.

These agreements contain representations and warranties made between pSivida, pSivida Inc., the Investor and Bausch & Lomb Incorporated as of the date of the such documents or other specific dates, and such representations and warranties should not be relied upon by any other person.
 
4. Warrants:
 
The following is a summary of the terms of the warrants:
 
·  
The warrants constitute options to acquire up to 5,700,000 ADSs at any time on or before the fifth anniversary of the issuance of the warrant.
 
·  
The per ADS exercise price under the warrant is US$1.80 and may be adjusted under certain circumstances, including, among others, in the event pSivida issues securities at a lower price than the price at which the warrant may be exercised or pSivida makes a pro rata issuance to shareholders.
 
·  
There is a limit of 4.99% in respect of the Investor and its affiliates’ beneficial ownership in pSivida, which may prevent it from exercising part of the warrant (this limit may be increased or decreased by the Investor upon written notice to pSivida).
 
·  
If there is a fundamental transaction (such as a transaction which involves a change in control of pSivida or a transfer of substantially all of its assets), pSivida will use its best endeavors to procure that the successor entity assumes all of the obligations of pSivida under the warrant.
 
·  
Additional warrants will be issued in the event that pSivida redeems all or a portion of the note in connection with an optional redemption or a sale of collateral. Such warrants will have an exercise price based on the average market price prior to their issuance.
 
The Form of Series A Warrant and Form of Series B Warrant were furnished on pSivida’s Form 6-K filed on July 31, 2006.
 
5. Amended and Restated Registration Rights Agreement:
 
The following is a summary of the amendments to the registration rights agreement:
 
·  
The effectiveness deadline for registering shares issuable pursuant to the note and warrants issued in November 2005 will be extended to October 15, 2006. If pSivida's registration statement is not effective by that date, pSivida will pay additional penalties of $765,000 and, from October 15, 2006 until the date on which the effectiveness failure is cured, 2.0% of the outstanding principal amount of the note per thirty day period.
 
·  
The effectiveness deadline for registering shares issuable pursuant to the warrants issued on September 14, 2006 will be December 31, 2006. If pSivida's registration statement registering those shares is not effective by that date, pSivida must pay penalties of 7.5% of the outstanding principal amount of the note and, from December 31, 2006 until the date on which the effectiveness failure is cured, 1.0% of the outstanding principal amount of the note per thirty day period.
 
·  
Subsequent registration of shares issuable pursuant to the warrants is required if certain events occur with respect to the trading volume or weighted average trading price of pSivida’s ordinary shares on the Australian Stock Exchange.
 
The Form of Amended and Restated Registration Rights Agreement was furnished on pSivida’s Form 6-K filed on July 31, 2006. The final version of the Amended and Restated Registration Rights Agreement is furnished on the Form 6-K to which this Supplemental Disclosure is also an Exhibit.

pSivida Limited
 
Amended and Restated Convertible Note
 
Issuance Date: November 16, 2005
Principal: U.S. $12,500,000

FOR VALUE RECEIVED, pSivida Limited, an Australian corporation (the "Company"), hereby promises to pay to the order of CASTLERIGG MASTER INVESTMENTS LTD. or registered assigns ("Holder") the amount set out above as the Principal (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the "Principal") when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest ("Interest") on any outstanding Principal at the Interest Rate, from the date set out above as the Issuance Date (the "Issuance Date") until the same becomes due and payable, whether upon an Interest Date (as defined below), the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Subordinated Convertible Note (including all Convertible Notes issued in exchange, transfer or replacement hereof, this "Note") amends, supplements, modifies and completely restates and supersedes the Subordinated Convertible Note, dated as of November 16, 2005 (the "Existing Note"), issued by the Company to the order of the Holder in the principal amount of $15,000,000, but shall not,
 
-1-

 

except as specifically amended hereby or as set forth in the Amendment Agreement (as defined below), constitute a release, satisfaction or novation of any of the obligations under the Existing Note or any other Transaction Document (as defined in the Securities Purchase Agreement, defined below). This Note is one of an issue of Subordinated Convertible Notes issued pursuant to the Amendment Agreement (the "Amendment Agreement") dated as of July 28, 2006 (collectively, the "Notes" and such other Convertible Notes, the "Other Notes" and the holders of the Other Notes, the "Other Holders")). Certain capitalized terms used herein are defined in Section 29.

(1)  MATURITY. On the Maturity Date, the Holder shall surrender this Note to the Company and the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges, if any. The "Maturity Date" shall be the date which is three (3) years after the Issuance Date, as may be extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) pursuant to clause (i), (ii) or (iii) of Section 4(a) shall have occurred and be continuing or any event shall have occurred and be continuing which with the passage of time and the failure to cure would result in an Event of Default pursuant to clause (i), (ii) or (iii) of Section 4(a) and (ii) through the date that is ten (10) Business Days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5) is delivered prior to the Maturity Date.
 
(2)  INTEREST; INTEREST RATE. Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable in arrears for each Calendar Quarter on the first (1st) day of the succeeding Calendar Quarter during the period beginning on the Issuance Date and ending on, and including, the Maturity Date (each, an "Interest Date") with the first Interest Date being January 1, 2006. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in ADRs ("Interest Shares"), or, at the option of the Company, in cash ("Cash Interest"), or a combination thereof. On or prior to the fifth (5th) Trading Day prior to each Interest Date (each, an "Interest Notice Due Date"), the Company shall deliver written notice (each, an "Interest Election Notice") to the Holder confirming that the Equity Conditions have been satisfied as of such Interest Notice Due Date and specifying the amount of Interest that shall be paid as Cash Interest and the amount of Interest that shall be paid in Interest Shares. Notwithstanding the foregoing, unless otherwise waived or consented to in writing by the Holder, the Company will not be permitted to issue on any Interest Date a number of Interest Shares (and must pay any excess in Cash Interest) which exceeds the Maximum Interest Share Amount. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable (rounded to the nearest whole share in accordance with Section 3(a)) ADRs equal to the quotient of (a) the amount of Interest payable on such Interest Date less any Cash Interest paid and (b) the Interest Conversion Price in effect on the applicable Interest Date. If any Interest Shares are to be paid on an Interest Date, then the Company shall (X) provided that the Company's transfer agent (the "Transfer Agent") is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer Program, credit such aggregate number of Interest Shares to which the Holder shall be entitled to the Holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the foregoing shall not apply, issue and deliver on the applicable Interest Date, to the address set forth in the register maintained by the Company for such purpose pursuant to
 
-2-

 

the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least two (2) Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled. In addition, upon payment of any Interest Shares, the Company shall deposit the corresponding number of Ordinary Shares representing the number of American Depositary Shares ("ADSs") underlying the ADRs and pay by wire transfer to the Depositary's account the ADS issuance fee of $0.04 per ADS to be issued, together with all applicable taxes and expenses otherwise payable under the terms of the Deposit Agreement for the deposit of Ordinary Shares and issuance of ADSs (including, without limitation, confirmation that any Australian stock transfer taxes in respect of such deposit (if any) have been paid by the Company), and the Company shall otherwise comply with and cause any other necessary party to comply with all the terms of the Deposit Agreement. Notwithstanding the foregoing, the Company shall not be entitled to pay Interest in Interest Shares and shall be required to pay such Interest in cash as Cash Interest on the applicable Interest Date if, unless consented to in writing by the Holder, during the period commencing on the applicable Interest Notice Due Date through the applicable Interest Date the Equity Conditions have not been satisfied. Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount in accordance with Section 3(b)(i). Upon the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to ten percent (10%). In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default. The Company's obligation to pay any taxes in respect of the issuance and delivery of Interest Shares, or to pay to the Holder any additional amounts associated with such taxes, shall be determined under Section 4(o) of the Securities Purchase Agreement.
 
(3)  CONVERSION OF NOTES. This Note shall be convertible into the Company's ADRs, on the terms and conditions set forth in this Section 3.
 
(a)  Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable ADRs in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of an ADR upon any conversion. If any conversion would result in the issuance of a fraction of an ADR, the Company shall round such fraction of an ADR up to the nearest whole share. The Company's obligation to pay any taxes in respect of the issuance and delivery of ADRs or Ordinary Shares, or to pay to the Holder any additional amounts associated with such taxes, shall be determined under Section 4(o) of the Securities Purchase Agreement.
 
In the event that the Company's Board of Directors should determine that the Company shall transform itself (whether by re-incorporation in the United States or otherwise) from a foreign private issuer (as defined under the Securities Act of 1933, as amended), all references to ADRs or ADSs shall be deemed references to whatever shares are then issued by the re-domiciled Company and all other provisions of this Agreement shall be
 
-3-

 

equitably adjusted by the parties hereto to the extent necessary or appropriate to reflect such new country of incorporation.

(b)  Conversion Rate. The number of ADRs issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the "Conversion Rate").
 
(i)  "Conversion Amount" means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which this (or any other) determination is being made, (B) accrued and unpaid Interest with respect to such Principal and (C) accrued and unpaid Late Charges with respect to such Principal and Interest.
 
(ii)  "Conversion Price" means, as of any Conversion Date (as defined below) or other date of determination, $2.00 per ADR (which is equivalent to $0.20 per Ordinary Share), subject to adjustment as provided herein.
 
(c)  Mechanics of Conversion.
 
(i)  Optional Conversion. To convert any Conversion Amount into ADRs on any date (a "Conversion Date"), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the "Conversion Notice") to the Company and (B) if required by Section 3(c)(iii), surrender this Note to a common carrier for delivery to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the second (2nd) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent. On or before the fifth (5th) Business Day following the date of receipt of a Conversion Notice (the "Share Delivery Date"), the Company shall (X) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate number of ADRs to which the Holder shall be entitled to the Holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the foregoing shall not apply, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of ADRs to which the Holder shall be entitled. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal not converted. The Person or Persons entitled to receive the ADRs issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such ADRs on the Conversion Date. Upon conversion of this Note, the Company shall deposit the corresponding number of Ordinary Shares representing the number of ADSs underlying the ADRs and pay by wire transfer to the Depositary's account the ADS issuance fee of $0.04 per ADS to be issued, together with all applicable taxes and expenses otherwise payable under the terms of the Deposit Agreement for the deposit of Ordinary Shares and issuance of ADSs (including, without
 
-4-

 

limitation, confirmation that any Australian stock transfer taxes in respect of such deposit (if any) have been paid by the Company), and the Company shall otherwise comply with and cause any other necessary party to comply with all the terms of the Deposit Agreement.

(ii)  Company's Failure to Timely Convert. If the Company shall fail to issue a certificate to the Holder or credit the Holder's balance account with DTC for the number of ADRs to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is five (5) Business Days after the Conversion Date (a "Conversion Failure"), then (A) the Company shall pay damages in cash to the Holder for each date of such Conversion Failure in an amount equal to an interest rate equal to 10% per annum applied to the product of (I) the sum of the number of ADRs not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (II) the Closing Sale Price of the ADRs on the Share Delivery Date and (B) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Company's obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the foregoing, if within three (3) Trading Days after the Company's receipt of the facsimile copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder's balance account with DTC for the number of ADRs to which the Holder is entitled upon such holder's conversion of any Conversion Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) ADRs to deliver in satisfaction of a sale by the Holder of ADRs issuable upon such conversion that the Holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three (3) Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions, if any) for the ADRs so purchased (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to issue such ADRs) shall be deemed to have been satisfied and shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such ADRs and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of ADRs, times (B) the Closing Bid Price on the Conversion Date.
 
(iii)  Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal, Interest and Late Charges converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.
 
(iv)  Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder
 
-5-

 

of Notes electing to have Notes converted on such date a pro rata amount of such holder's portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of ADRs issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of ADRs not in dispute and resolve such dispute in accordance with Section 24.

(d)  Limitations on Conversions
 
(i)  Beneficial Ownership. The Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holder's affiliates) would beneficially own (directly or indirectly) in excess of 4.99% (the "Maximum Percentage") of the number of Ordinary Shares outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the number of Ordinary Shares beneficially owned (directly or indirectly) by the Holder and its affiliates shall include the number of Ordinary Shares represented by the ADRs issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude the number of Ordinary Shares represented by the ADRs or otherwise which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company beneficially owned by the Holder or any of its affiliates (including, without limitation, any Other Notes or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this Section 3(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Section 3(d), in determining the number of outstanding Ordinary Shares, the Holder may rely on the number of outstanding Ordinary Shares as reflected in (x) the Company's most recent Form 20-F, Form 6-K or other public filing with the Securities and Exchange Commission, as the case may be (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of Ordinary Shares outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within two (2) Business Days confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder and its affiliates since the date as of which such number of outstanding Ordinary Shares was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes.
 
(ii)  Principal Market Regulation. The Company shall not be obligated to issue any ADRs upon conversion of this Note, and the Holder of this Note shall not have the right to receive upon conversion of this Note any ADRs, if the issuance of such ADRs

would exceed the aggregate number of ADRs which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants or otherwise without breaching the Company's obligations under the rules or regulations of the Principal Market (or such other Eligible Market on which the ADRs or Ordinary Shares are listed) and the ASX (the "Exchange Cap"), except that such limitation shall not apply in the event that the Company obtains the approval of its shareholders as required by the applicable rules of the Principal Market and the ASX listing rules for issuances in excess of such amount. Until such approval is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the "Purchasers") shall be issued in the aggregate, upon conversion or exercise, as applicable, of Notes or Warrants, or otherwise any ADRs in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to the applicable Purchaser pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the "Exchange Cap Allocation"). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser's Notes, the transferee shall be allocated a pro rata portion of such Purchaser's Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Notes shall convert all of such holder's Notes into a number of ADRs which, in the aggregate, is less than such holder's Exchange Cap Allocation, then the difference between such holder's Exchange Cap Allocation and the number of ADRs actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

(4)  RIGHTS UPON EVENT OF DEFAULT.
 
(a)  Event of Default. Each of the following events shall constitute an "Event of Default":
 
(i)  the failure of the applicable Registration Statement required to be filed pursuant to the Registration Rights Agreement to be declared effective by the SEC on or prior to the date that is sixty (60) days after the applicable Effectiveness Deadline (as defined in the Registration Rights Agreement), or, while the applicable Registration Statement is required to be maintained effective pursuant to the terms of the Registration Rights Agreement, the effectiveness of the applicable Registration Statement lapses for any reason (including, without limitation, the issuance of a stop order) or is unavailable to any holder of the Notes for sale of all of such holder's Registrable Securities (as defined in the Registration Rights Agreement) in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of ten (10) consecutive days or for more than an aggregate of thirty (30) days in any 365-day period (other than days during an Allowable Grace Period (as defined in the Registration Rights Agreement));

(iv)  the Company's failure to pay to the Holder any amount of Principal when and as due or any Interest, Late Charges or other amounts within three Business Days of the date when and as due under this Note (including, without limitation, the Company's failure to pay any redemption payments) or any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby to which the Holder is a party;
 
(v)  any Indebtedness, the aggregate of which obligation(s) exceed(s) US$250,000.00 (or the equivalent in one or more other currencies) individually or in the aggregate is declared to be or otherwise becomes due and payable prior to its specified maturity (other than as a result of a mandatory prepayment not attributable to an event of default) or with respect to which the Company or any of its Subsidiaries fails to make any payment at the maturity date as and when due;
 
(vi)  the Company or any of its Material Subsidiaries (as such term is defined under Regulation S-K under the Securities and Exchange Act of 1933, as amended), pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal, foreign or state law for the relief of debtors (collectively, "Bankruptcy Law"), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a "Custodian"), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;
 
(vii)  a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company or any of its Material Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Material Subsidiaries or (C) orders the liquidation of the Company or any of its Material Subsidiaries;
 
(viii)  a final judgment or judgments for the payment of money aggregating in excess of $2,500,000 are rendered against the Company or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however, that any such judgment shall not give rise to an Event of Default under this subsection (viii) if and for so long as (A) the amount of such judgment is covered by a valid and binding policy of insurance between the defendant and the insurer covering full payment thereof and (B) such insurer has been notified, and has not disputed the claim made for payment, of the amount of such judgment;
 
-8-

 
 
(ix)  the Company breaches any material representation, warranty, covenant or other term or condition of any Transaction Document in any material respect, except, in the case of a breach of a covenant which is curable, only if such breach continues for a period of at least ten (10) consecutive Business Days after notice from any Holder or the Company becomes or reasonably should be expected to have become aware of such breach;
 
(x)  any material breach or failure in any respect to comply with either of Sections 8 or 15 of this Note; or
 
(xi)  any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes.
 
(b)  Redemption Right. Promptly after the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall deliver written notice thereof via facsimile and overnight courier (an "Event of Default Notice") to the Holder. At any time after the earlier of the Holder's receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default and until 30 days after such Event of Default has been cured, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (the "Event of Default Redemption Notice") to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (x) the Conversion Amount to be redeemed and (y) the Redemption Premium and (ii) the product of (A) the Conversion Rate with respect to such Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the Closing Sale Price of the ADRs on the date immediately preceding such Event of Default (the "Event of Default Redemption Price"). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 13.
 
(5)  RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.
 
(a)  Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless, and shall use its best endeavors to procure that, (i)  the Successor Entity (if other than the Company) assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of such Successor Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes held by such holder and having similar ranking to the Notes, and reasonably satisfactory to the Required Holders and (ii) the Successor Entity is a publicly traded corporation whose common shares (or whose American Depositary Shares) are quoted on or listed for trading on an
 
-9-

 

Eligible Market. Upon the occurrence of any Fundamental Transaction, such Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the "Company" shall refer instead to such Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, such Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the ADRs (or other securities, cash, assets or other property) purchasable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such publicly traded common shares (or their equivalent) of the Successor Entity (including its Parent Entity), as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(b)  Redemption Right. No sooner than thirty (30) days nor later than ten (10) days prior to the consummation of a Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a "Change of Control Notice"); provided that in no case shall the Company deliver or be required to deliver such Change of Control Notice prior to the public announcement of such Change of Control. At any time during the period beginning after the Holder's receipt of a Change of Control Notice and ending on the date of the consummation of such Change of Control (or, in the event a Change of Control Notice is not delivered at least ten (10) days prior to a Change of Control, at any time on or after the date which is ten (10) days prior to a Change of Control and ending ten (10) days after the consummation of such Change of Control), the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof ("Change of Control Redemption Notice") to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company at a price equal to the greater of (i) the product of (x) the Conversion Amount being redeemed and (y) the quotient determined by dividing (A) the Closing Sale Price of the ADRs immediately following the public announcement of such proposed Change of Control by (B) the Conversion Price and (ii) the product of Change of Control Premium and the Conversion Amount being redeemed (the "Change of Control Redemption Price"). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 13 and shall have priority to payments to shareholders in connection with a Change of Control.
 
(6)  RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.
 
(a)  Purchase Rights. If at any time the Company, directly or indirectly, grants, issues or sells any Options, Convertible Securities or rights to purchase shares, warrants, securities or other property pro rata to the record holders of any class of Ordinary Shares (the "Purchase Rights"), then the Holder will be entitled to acquire, to the extent permitted by applicable Law, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of Ordinary
 
-10-

 

Shares underlying the ADRs acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Ordinary Shares are to be determined for the grant, issue or sale of such Purchase Rights.

(b)  Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of ADRs or Ordinary Shares are entitled to receive securities or other assets with respect to or in exchange for ADRs or Ordinary Shares (a "Corporate Event"), the Company shall make appropriate provision, to the extent not prohibited by applicable law, to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, (i) in addition to the ADRs receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such ADRs had such ADRs been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the ADRs otherwise receivable upon such conversion, such securities or other assets received by the holders of ADRs or Ordinary Shares in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to ADRs) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.
 
(7)  RIGHTS UPON ISSUANCE OF OTHER SECURITIES.
 
(a)  Adjustment of Conversion Price upon Issuance of Ordinary Shares. If and whenever on or after the Subscription Date, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any Ordinary Shares (including those underlying any ADRs and the issuance or sale of Ordinary Shares owned or held by or for the account of the Company, but excluding Ordinary Shares deemed to have been issued or sold by the Company in connection with any Excluded Security) for a consideration per Ordinary Share (the "New Issuance Price") less than a price (the "Applicable Price") equal to (i) one-tenth (1/10th) of the Conversion Price (in the case of ADRs) or (ii) the Conversion Price (in the case that the Conversion Price is determined by reference to the Ordinary Shares) in effect immediately prior to such issue or sale (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Issuance Price. Appropriate and equitable adjustment to the terms and provisions of this Note shall be made in the event of any change to the ratio of ADRs to Ordinary Shares represented thereby. For purposes of determining the adjusted Conversion Price under this Section 7(a), the following shall be applicable:
 
(i)  Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one Ordinary Share is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than
 
 
-11-

 
 
the Applicable Price, then such Ordinary Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the "lowest price per share for which one Ordinary Share is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one Ordinary Share upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Ordinary Shares or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Ordinary Shares upon conversion or exchange or exercise of such Convertible Securities.

(ii)  Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one Ordinary Share is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then such Ordinary Share shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the "price per share for which one Ordinary Share is issuable upon such conversion or exchange or exercise" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one Ordinary Share upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Ordinary Shares upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.
 
(iii)  Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Ordinary Shares changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Subscription Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Ordinary Shares deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

 
-12-

 
 
(iv)  Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Ordinary Shares, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount paid by the purchaser therefor. If any Ordinary Shares, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Ordinary Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Ordinary Shares, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined in good faith by the Board of Directors of the Company.
 
(v)  Record Date. If the Company takes a record of the holders of Ordinary Shares for the purpose of entitling them (A) to receive a dividend or other distribution payable in Ordinary Shares, Options or in Convertible Securities or (B) to subscribe for or purchase Ordinary Shares, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Ordinary Shares deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.
 
(b)  Adjustment of Conversion Price upon Pro Rata Bonus Issue of Ordinary Shares. If the Company makes a pro rata bonus issue of Ordinary Shares to its shareholders prior to conversion of the Note, and the Note is not converted prior to the record date for the issue, the Note will, when converted, entitle the holder to the number of ADRs that would ordinarily be received under Section 3, plus the number of bonus Ordinary Shares which would have been issued to the Holder if the Note had been converted prior to the record date.
 
(c)  Adjustment of Conversion Price upon Subdivision or Combination of Ordinary Shares. If the Company at any time on or after the Subscription Date subdivides (by any share split, share dividend, recapitalization or otherwise) one or more classes of its outstanding ADRs (or Ordinary Shares underlying such ADRs) into a greater number of ADRs (or Ordinary Shares), the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse share split or otherwise) one or more classes of its outstanding ADRs (or Ordinary Shares) into a smaller number of ADRs (or Ordinary Shares), the Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment under this Section 7(d) shall be subject to (and will be
 
-13-

 

correspondingly reorganised in a manner which is permissible under, or necessary to comply with) the ASX Listing Rules or the rules of any Eligible Market in force at the relevant time and shall become effective at the close of business on the date the subdivision or combination becomes effective.
 
(d)  Capital reorganizations. If there is a reorganisation of the capital of the Company, the number of ADRs applicable to the Note and/or the Conversion Price of the Note will be correspondingly reorganised in a manner, which is permissible under, or necessary to comply, with the ASX Listing Rules or the rules of any other Eligible Market in force at the relevant time. Subject to the above, if there is a reorganisation of the capital of the Company, the number of ADRs applicable to the Note or the Conversion Price or both will be reorganised so that the Holder of the Note will not receive a benefit that holders of Ordinary Shares do not receive. The Company shall give notice to the Holder of the Note of any adjustments to the number of ADRs which are to be issued on conversion of the Note or to the Conversion Price. Before a Note is converted, all adjustment calculations are to be carried out including all fractions (in relation to each of the number of ADRs applicable to the Note and the Conversion Price), but on conversion the number of ADRs issued is rounded down to the next lower whole number and the Conversion Price rounded up to the next higher cent.
 
(e)  Other Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of share appreciation rights, phantom share rights or other rights with equity features), then the Company's Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder under this Note; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 7.
 
(f)  Adjustment. If on April 30, 2007, the Subsequent Conversion Price is less than the then applicable Conversion Price, then the Conversion Price shall be reset to the Subsequent Conversion Price.
 
(8)  HOLDER'S RIGHT OF OPTIONAL REDEMPTION. On each Holder Optional Redemption Date, the Holder shall have the right, in its sole discretion, to require that the Company redeem (each a "Holder Optional Redemption") up to $6,250,000 in Principal amount of the Note plus accrued and unpaid Interest with respect to such Principal and accrued and unpaid Late Charges with respect to such principal and Interest (the "Optional Redemption Amount") by delivering written notice thereof (a "Holder Optional Redemption Notice" and, collectively with the Event of Default Redemption Notice and the Change of Control Redemption Notice, the "Redemption Notices" and each a "Redemption Notice") to the Company no later than ten (10) Business Days after the applicable Holder Optional Redemption Date. The Holder Optional Redemption Notice shall indicate the amount of the applicable Optional Redemption Amount the Holder is electing to have redeemed on such Optional Redemption Exercise Date (the "Holder Optional Redemption Amount") and the date of such redemption (the "Optional Redemption Exercise Date"); provided, however, that (a) such Holder Optional Redemption Amount indicated shall not exceed the Optional Redemption Amount and (b) such Optional Redemption Exercise Date shall not be less than ten (10) Business Days after the date of delivery of such Holder Optional Redemption Notice. The portion of this Note subject to redemption pursuant to this Section 8 shall be redeemed by the Company in cash
 
-14-

 

on the applicable Holder Optional Redemption Date at a price equal to the Holder Optional Redemption Amount being redeemed (the "Holder Optional Redemption Price" and, collectively with the Event of Default Redemption Price and the Change of Control Redemption Price, the "Redemption Prices" and, each a "Redemption Price").
 
Such Holder covenants that it will comply with Section 2(j) of the Securities Purchase Agreement.
 
(9)  COMPANY'S RIGHT OF MANDATORY CONVERSION.
 
(a)  Mandatory Conversion. If at any time from and after the sixtieth (60th) day after the Additional Effective Date (as defined in the Registration Statement) (the "Mandatory Conversion Eligibility Date"), (i) the Weighted Average Price of the ADRs exceed for each of any twenty (20) out of twenty-five (25) consecutive Trading Days following the Mandatory Conversion Eligibility Date (the "Mandatory Conversion Measuring Period"), 200% of the applicable Conversion Price (subject to appropriate adjustments for share splits, share dividends, share combinations and other similar transactions after the Subscription Date) and (ii) the Equity Conditions shall have been satisfied (or waived in writing by the Holder), during the period commencing on the Mandatory Conversion Notice Date through the applicable Mandatory Conversion Date (each, as defined below), the Company shall have the right to require the Holder to convert all, or any portion, of the Conversion Amount then remaining under this Note as designated in the Mandatory Conversion Notice into fully paid, validly issued and nonassessable ADRs in accordance with Section 3(c) hereof at the Conversion Rate as of the Mandatory Conversion Date (a "Mandatory Conversion"). The Company may exercise its right to require conversion under this Section 9(a) by delivering within not more than three (3) Business Days following the end of any such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the "Mandatory Conversion Notice" and the date all of the holders received such notice is referred to as the "Mandatory Conversion Notice Date"). The Mandatory Conversion Notice shall be irrevocable. The Mandatory Conversion Notice shall state (i) the Business Day selected for the Mandatory Conversion in accordance with this Section 9(a), which Business Day shall be at least twenty (20) Business Days but not more than sixty (60) Business Days following the Mandatory Conversion Notice Date (the "Mandatory Conversion Date"), (ii) the aggregate Conversion Amount of the Notes subject to mandatory conversion from all of the holders of the Notes pursuant to this Section 9 (and analogous provisions under the Other Notes) and (iii) the number of ADRs to be issued to such Holder on the Mandatory Conversion Date.
 
(b) Pro Rata Conversion Requirement. If the Company elects to cause a conversion of any Conversion Amount of this Note pursuant to Section 9(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. All Conversion Amounts converted by the Holder after the Mandatory Conversion Notice Date shall reduce the Conversion Amount of this Note required to be converted on the Mandatory Conversion Date. If the Company has elected a Mandatory Conversion, the mechanics of conversion set forth in Section 3(c) shall apply, to the extent applicable, as if the Company and the Transfer Agent had received from the Holder on the Mandatory Conversion Date a Conversion Notice with respect to the Conversion Amount being converted pursuant to the Mandatory Conversion.
 
-15-

 
 
(10)  COMPANY'S RIGHT OF OPTIONAL REDEMPTION.
 
(a)  Company Optional Redemption. At any time after the Issuance Date, the Company shall have the right to redeem all or any portion of the Conversion Amount then remaining under this Note (a "Company Optional Redemption"). The portion of this Note subject to redemption pursuant to this Section 10 shall be redeemed by the Company in cash at a price equal to 108% of the Conversion Amount being redeemed (the "Company Optional Redemption Price"). The Company may exercise its redemption right under this Section 10 by delivering a written notice thereof by confirmed facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the "Company Optional Redemption Notice" and the date such notice is delivered to all the holders is referred to as the "Company Optional Redemption Notice Date"). The Company Optional Redemption Notice shall be irrevocable. The Company Optional Redemption Notice shall state (A) the date on which the Company Optional Redemption shall occur (the "Company Optional Redemption Date") which date shall be not less than thirty (30) days nor more than sixty (60) days after the Company Optional Redemption Notice Date, (B) the aggregate Principal amount (the "Company Optional Redemption Amount") of the Notes which the Company has elected to be subject to Optional Redemption from all of the holders of the Notes pursuant to this Section 10 (and analogous provisions under the Other Notes) on the Company Optional Redemption Date, (C) that in connection with the Company Optional Redemption the Company shall issue to the Holder Series B Warrants and (D) the number of ADSs for which such Series B Warrants shall become exercisable shall be equal to the quotient of (1) 30% of the Conversion Amount being redeemed and (2) the then applicable Conversion Price. The Company will make a public announcement containing the information set forth in the Company Optional Redemption Notice on or before the Company Optional Redemption Notice Date. The Company may not effect more than one (1) Company Optional Redemption during any consecutive thirty (30) Trading Day period. Notwithstanding anything to the contrary in this Section 10, until the Company Optional Redemption Price is paid, in full, the Company Optional Redemption Amount may be converted, in whole or in part, by the holders of Notes into ADSs pursuant to Section 3. All Conversion Amounts converted by the Holder after the Company Optional Redemption Notice Date shall reduce the Conversion Amount of this Note required to be redeemed on the Company Optional Redemption Date. Redemptions made pursuant to this Section 10 shall be made in accordance with Section 13.
 
(b)  Pro Rata Redemption Requirement. If the Company elects to cause a Company Optional Redemption pursuant to Section 10(a), then it must simultaneously take the same action with respect to the Other Notes. If the Company elects to cause a Company Optional Redemption pursuant to Section 10(a) (or similar provisions under the Other Notes) with respect to less than all of the principal amount of the Notes then outstanding, then the Company shall require redemption of a Principal amount from the Holder and each holder of the Other Notes equal to the product of (i) the aggregate principal amount of Notes which the Company has elected to cause to be redeemed pursuant to Section 8(a), multiplied by (ii) the fraction, the numerator of which is the sum of the initial principal amount of Notes purchased by such holder and the denominator of which is the initial principal amounts of Notes purchased by all holders holding outstanding Notes (such fraction with respect to each holder is referred to as its "Redemption Allocation Percentage", and such amount with respect to each holder is
 
-16-

 

referred to as its "Pro Rata Redemption Amount"); provided that in the event that the initial holder of any Notes has sold or otherwise transferred any of such holder's Notes, the transferee shall be allocated a pro rata portion of such holder's Redemption Allocation Percentage and Pro Rata Redemption Amount.
 
(11)  NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Constitution, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any Ordinary Shares underlying the Conversion Shares receivable upon the conversion of this Note above the Conversion Price then in effect and (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Conversion Shares upon the conversion of this Note.
 
(12)  SUBORDINATION TO PERMITTED SENIOR INDEBTEDNESS; SECURITY.
 
(a)  Subordination.

If any Guarantor shall be required to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Transaction Document;
 
(i) the amount so payable shall be increased to the extent necessary so that after making all required deductions and withholdings (including Taxes on amounts payable to any Buyer pursuant to this sentence) each Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made,

-7-

 

arise from any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Transaction Document (collectively, "Other Taxes").
 
(b) Each Guarantor hereby indemnifies and agrees to hold the Collateral Agent and each Buyer (each an "Indemnified Party") harmless from and against Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 11) paid by any Indemnified Party  as a result of any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Transaction Document, and any liability (including penalties, interest and expenses for nonpayment, late payment or otherwise) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted.  This indemnification shall be paid within 30 days from the date on which the Collateral Agent or such Buyer makes written demand therefor, which demand shall identify the nature and amount of such Taxes or Other Taxes.
 
(c) If any Guarantor fails to perform any of its obligations under this Section 11, such Guarantor shall indemnify the Collateral Agent and each Buyer for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations of the Guarantors under this Section 11 shall survive the termination of this Guaranty and the payment of the Obligations and all other amounts payable hereunder.

SECTION 12.   Miscellaneous.
 
(a)   Each Guarantor will make each payment hereunder in lawful money of the United States of America and in immediately available funds to each Buyer, at such address specified by such Buyer from time to time by notice to the Guarantors.
 
(b)   No amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by each Guarantor and each Buyer, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.
 
(c)   No failure on the part of any Buyer to exercise, and no delay in exercising, any right hereunder or under any other Transaction Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder or under any Transaction Document preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the Collateral Agent and the Buyers provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights of the Collateral Agent and the Buyers under any Transaction Document against any party thereto are not conditional or contingent on any attempt by the Collateral Agent or any Buyer to exercise any of their respective rights under any other Transaction Document against such party or against any other Person.
 
(d)   Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or
 
-8-

 
 
unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

(e)   This Guaranty shall (i) be binding on each Guarantor and its respective successors and assigns, and (ii) inure, together with all rights and remedies of the Collateral Agent hereunder, to the benefit of the Collateral Agent, the Buyers and their respective successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, the Collateral Agent and any Buyer may assign or otherwise transfer its rights and obligations under the Securities Purchase Agreement or any other Transaction Document to any other Person in accordance with the terms thereof, and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Collateral Agent or Buyer, as the case may be, herein or otherwise. None of the rights or obligations of any Guarantor hereunder may be assigned or otherwise transferred without the prior written consent of each Buyer.
 
(f)   This Guaranty reflects the entire understanding of the transaction contemplated hereby and shall not be contradicted or qualified by any other agreement, oral or written, entered into before the date hereof.
 
(g)   Section headings herein are included for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.
 
(H)   THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED THEREIN WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES.

WHEREAS, pSivida Limited, an Australian corporation (the “Parent”), and each party listed as a “Buyer” on the Schedule of Buyers attached thereto (each a “Buyer”, and collectively, the “Buyers”) are parties to the Securities Purchase Agreement pursuant to which the Parent sold, and the Buyers purchased, the “Notes” (as defined therein, and as such Notes may be amended, restated, replaced or otherwise modified from time to time in accordance with the terms thereof, collectively, the “Notes”);
 
WHEREAS, the Parent owns 100% of the voting stock of the Assignor;
 
WHEREAS, contemporaneously herewith, the Assignor has executed and delivered to the Assignee (for the benefit of the Buyers), a guaranty (the “Guaranty”) guaranteeing payment by Parent of amounts due under the Transaction Documents (as defined in the Amendment Agreement); and
 
WHEREAS, the Assignor is a party to an Amended and Restated License Agreement dated December 9, 2003, as amended by that certain Amendment No. 1 thereto (as amended, the “B&L License Agreement”) with Bausch & Lomb Incorporated (the “Licensee”) pursuant to which it has licensed certain intellectual property rights to the Licensee for, among other things, the purposes of producing the Retisert and Vitrasert product lines and in connection therewith receives certain royalty payments from the Licensee as further described in the B&L License Agreement (the “B&L Royalty Payments”);
 
WHEREAS, pursuant to the terms of the Amendment Agreement, the Assignor has agreed to enter into this Collateral Assignment to secure the payment by the Assignor, as and when due and payable, of all "Guaranteed Obligations" under (and as defined in) the Guaranty, including the punctual payment, as and when due and payable, by stated maturity or otherwise, of all the payments by the Parent, as and when due and payable (by scheduled maturity, required prepayment, acceleration, demand or otherwise), of any and all amounts from time to time owing by Parent in respect of the Notes, including, without limitation, all interest that accrues after the commencement of any proceeding commenced by or against Parent or any Guarantor (as defined in the Guaranty) under any provision of the Bankruptcy Code (Chapter 11 of Title 11 of the United States Code) or under any other bankruptcy or insolvency law, assignments for the

benefit of creditors, formal or informal moratoria, compositions, or extensions generally with creditors, or proceedings seeking reorganization, arrangement, or other similar relief (an “Insolvency Proceeding”), whether or not the payment of such interest is unenforceable or is not allowable due to the existence of such Insolvency Proceeding, and all reasonable fees, commissions, expense reimbursements, indemnifications and all other amounts due or to become due under the Notes (collectively the “Secured Obligations”).

NOW, THEREFORE, in consideration of the premises set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Assignor hereby agrees as follows:
 
1.    ASSIGNMENT AS SECURITY.
 
The Assignor hereby collaterally assigns and grants to the Assignee as security for the payment and performance in full of the Secured Obligations when due, a security interest in all of the Assignor’s right, title and interest in and to the Assignor’s right to receive the B&L Royalty Payments from the Licensee.
 
All capitalized terms used herein and not otherwise defined herein shall have the meanings given to such terms in the Transaction Documents.
 
2.    REPRESENTATIONS, WARRANTIES AND COVENANTS.
 
(a)    Except as referenced herein or as disclosed to the Assignee, the B&L License Agreement, since its execution and delivery by the Assignor, has not been modified or amended.
 
(b)    The Assignor has not delivered or received any notices of default under the B&L License Agreement. The Assignor is not in default under any of the terms of the B&L License Agreement, and there are no events which, with the giving of notice or the passage of time or both, would constitute a material default by the Assignor under the B&L License Agreement.
 
(c)    To the best of the Assignor’s knowledge, the Licensee is not in default under any of the terms of the B&L License Agreement, and there are no events which, with the giving of notice or the passage of time or both, would constitute a default by the Licensee under the B&L License Agreement.
 
(d)    The Assignor has delivered to the Assignee a true and complete copy of the B&L License Agreement and any written amendments or agreements modifying, waiving or otherwise altering the terms thereof.
 
(e)    The Assignor will perform and observe all of the terms, covenants and conditions required to be performed and observed by the Assignor, and do all things required by the B&L License Agreement to preserve and to keep unimpaired its rights, under the B&L License Agreement.

(f)    The Assignor will (i) promptly notify the Assignee of its receipt of any notice from the Licensee of any default by the Assignor in the performance or observance of any of the terms, covenants or conditions on its part to be performed or observed under the B&L License Agreement, and (ii) promptly cause a copy of any such notice received by the Assignor from the Licensee to be delivered to the Assignee.
 
(g)    The Assignor will not, without the prior written consent of the Assignee, which consent shall not be unreasonably withheld or delayed so long as no Event of Default (as defined below) has occurred and is continuing, (i) modify or supplement the B&L License Agreement in any material respect (if such modification or supplement would materially diminish or impair any of the collateral pledged to the Assignee for the Secured Obligations pursuant to this Assignment or the Assignee's security interest therein) or terminate or cancel the B&L License Agreement, or (ii) consent or refuse to consent to any action taken or to be taken by the Licensee or anyone else under the B&L License Agreement, if such consent or refusal to consent would materially diminish or impair any of the collateral pledged to the Assignee for the Secured Obligations pursuant to this Assignment or the Assignee’s security interest therein.
 
3.    INTELLECTUAL PROPERTY COVENANTS.  The Assignor hereby agrees that:
 
(a)    The Assignor may not, to the extent prohibited by the B&L License Agreement or not consented to by B&L, abandon any Licensed Patents or Licensor Improved Patents (as such terms are defined in the B&L License Agreement) without the prior written consent of the Assignee, and if any Licensed Patents or Licensor Improved Patents is infringed or misappropriated or otherwise violated by a third party, the Assignor shall take such action as the Assignee shall reasonably deem appropriate under the circumstances to enforce such Licensed Patents or Licensor Improved Patents.
 
(b)    In the event that, upon a default by the Assignor in the performance of or compliance with any provision of the B&L License Agreement, the Licensee notifies the Assignor that it has elected to terminate the B&L License Agreement as a result of such default: (A) the Assignor shall promptly notify the Assignee in writing of such notice, describing in reasonable detail the nature of such default; (B) the Assignee shall have the right and opportunity, but not the obligation, to cure such default within the period provided for in the B&L License Agreement for cure; and (C) during such period, the Assignor shall not terminate the B&L License Agreement. Any payment made or act done by the Assignee to cure such default shall not constitute an assumption by the Assignee of the B&L License Agreement or of any obligations of the Licensee thereunder.
 
(c)    From and after the occurrence of any Event of Default and until the later of (A) the last day during which such Event of Default is continuing and (B) until such time as all Secured Obligations then due and payable have been paid in full (the “Default Period”):
 
(i)    all royalties, dividends, distributions, interest and other payments that are received by the Assignor pursuant to the B&L License Agreement shall be received in trust for the benefit of the Assignee, shall be segregated from other funds of the Assignor, and shall be forthwith paid over to the Assignee as pledged interests in
 
-3-

 
 
the exact form received with any necessary endorsement, to be held by the Assignee as pledged interests and as further collateral security for the Secured Obligations;

(ii)    the Assignor shall, pursuant to written notice to the Assignor from the Assignee: (A) cease any use of the Licensed Patents or Licensor Improved Patents for any purpose described in such notice that involves the right to make, have made, use, sell, offer to sell, and import First Generation Exclusive Licensed Products and Vitrasert Licensed Product in the Licensed Field (as such terms are defined in the B&L License Agreement) and (B) assign all of the Assignor's right, title and interest in and to the B&L License Agreement to the Assignee for the duration of such Default Period; and
 
(iii)    the Assignor shall grant to the Assignee an exclusive, irrevocable, royalty-free, worldwide right and license, with exclusive right to sublicense, under the Assignee's interest in the Licensed Patents and Licensor Improvement Patents, solely to make, have made, use, sell, offer to sell, and import First Generation Exclusive Licensed Products and Vitrasert Licensed Product in the Licensed Field (as such terms are defined in the B&L License Agreement); such license shall be subject to the B&L License Agreement and terminate on the final day of the Default Period.
 
4.    TERMS AND CONDITIONS.
 
(a)    Prior to any failure by Parent and Assignor to make any payment due under the Note within the applicable cure period (an “Event of Default”), if the Assignor has any right, privilege or claim against the Licensee under the B&L License Agreement and the failure by the Assignor to enforce such right, privilege or claim would be reasonably likely to materially diminish or impair any of the collateral pledged to the Assignee for the Secured Obligations pursuant to this Assignment or the Assignee's security interest therein, the Assignor will take all actions necessary, in its good faith business judgment, to enforce such right, privilege or claim.
 
(b)    The Assignor hereby irrevocably authorizes and empowers the Assignee, at any time during a Default Period, to (i) assert, either directly (to the extent of the Secured Obligations) or on behalf of the Assignor, any claims and demands and enforce, either directly or on behalf of the Assignor, any rights and remedies which the Assignor may have, from time to time, during such period, against the Licensee under the B&L License Agreement, and (ii) to collect any B&L Royalty Payment or other amounts due to the Assignor under the B&L License Agreement up to an amount equal to the amount of any outstanding Secured Obligations then due and payable and apply such amounts to such Secured Obligations in such manner as the Assignee shall elect, until such time as all Secured Obligations then due and payable have been paid in full. Simultaneously with the execution and delivery of this Assignment, the Assignor shall execute a notice to be addressed to the Licensee substantially in the form attached hereto as Exhibit A. (the “Payment Direction Notice”). The Assignee shall be authorized to send the Payment Direction Notice to the Licensee upon the occurrence of an Event of Default directing the Licensee to remit during the Default Period any and all B&L Royalty Payments to the Assignee when payable under the B&L License Agreement up to an aggregate amount equal to the amount of the outstanding Secured Obligations then due and
 
-4-

 
 
payable. The Assignee is authorized to insert in such Payment Direction Notice a description of the account into which any B&L Royalty Payments are to be remitted (which account description may be changed by the Assignee from time to time by delivery of a notice to the Licensee). The Assignee shall execute a cancellation of the Payment Direction Notice promptly following the end of the Default Period.

(c)    The Assignor hereby irrevocably makes, constitutes and appoints the Assignee as the Assignor’s true and lawful attorney-in-fact (such power being coupled with an interest) for the purpose of enabling the Assignee or its designated agent to take any or all of the actions contemplated by clauses (a) and (b) above.
 
(d)    The Assignor hereby acknowledges and agrees that it shall remain liable under the B&L License Agreement to observe and perform all of the conditions and obligations to be observed or performed by the Assignor thereunder, and neither this Assignment, nor any action taken by the Assignee pursuant hereto, shall cause the Assignee to be deemed to have assumed any of the obligations or liabilities of the Assignor under the B&L License Agreement; provided, however, that, notwithstanding anything to the contrary herein, in the event that royalties are owed to a third party based on the B&L Royalty Payments, the Assignee shall, at such time as it is collecting the B&L Royalty payments with respect to products other than products in the Collateral Product Lines (as defined in the Amendment Agreement), be responsible for paying any such royalties from the B&L Royalty Payments. The Assignor further agrees to indemnify, protect, defend and hold the Assignee harmless from and against any claims or demands by the Licensee under the B&L License Agreement, except to the extent such claims or demands result solely and directly from the Assignee’s gross negligence or willful misconduct as determined by a final judgment of a court of competent jurisdiction.
 
(e)    The Assignor hereby agrees to keep the Assignee reasonably informed of all circumstances bearing upon the exercise of the Assignor’s rights and remedies under the B&L License Agreement. In no event shall the Assignor waive, amend, alter or modify any of its rights or remedies under the B&L License Agreement, if such waiver, amendment, alteration or modification would materially diminish or impair any of the collateral pledged to the Assignee for the Secured Obligations pursuant to this Assignment or the Assignee's security interest therein, without the prior written consent of the Assignee, which consent shall not be unreasonably withheld or delayed so long as no Event of Default has occurred and is continuing.
 
(f)    This Collateral Assignment shall continue in full force and effect until all of the Secured Obligations have been indefeasibly paid or performed in full, at which time the Assignee's interest in the B&L License Agreement and any other rights assigned to the Assignee hereunder shall be automatically released. The Assignee shall, promptly upon request by the Assignor, execute such additional documentation to evidence such release.
 
(g)    No delay by the Assignee in the exercise of its rights hereunder shall constitute a waiver of any such rights. A waiver by the Assignee of a particular Event of Default shall not constitute a waiver of any subsequent Event of Default. Any waiver by the Assignee of any right hereunder on one occasion shall not constitute a waiver on any other occasion.
 
-5-

 
 
(h)    The Assignor hereby authorizes the Assignee to file one or more Uniform Commercial Code financing or continuation statements, and amendments thereto, necessary to perfect the security interest granted to the Assignee hereunder. The Assignee shall execute an appropriate release promptly upon the termination of this Assignment
 
5.    GENERAL CONDITIONS.
 
(a)    This Collateral Assignment shall be binding upon, and shall inure to the benefit of, the respective successors and permitted assigns of the parties hereto.
 
(b)    This Collateral Assignment shall be construed and enforced in accordance with the internal laws of the State of New York.
 
(c)    The Assignor shall pay all reasonable attorneys’ fees and expenses which the Assignee may hereafter incur in enforcing any of its rights hereunder.

Each Subsequent Registration Statement prepared pursuant hereto shall register for resale at least that number of ADRs equal to
 
the Subsequent Required Registration Amount as of the date such Registration Statement is initially filed with the SEC.

In the event that an Investor sells or otherwise transfers any of such Investor's Registrable Securities, each transferee shall be allocated a pro rata portion of the then remaining number of Registrable Securities included in such Registration Statement for such transferor. Any ADRs included in a Registration Statement and which remain allocated to any Person which ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Investors, pro rata based on the number of Registrable Securities then held by such Investors which are covered by such Registration Statement. Other than as permitted by Section 4(k) of the Securities Purchase Agreement, in no event shall the Company include any securities other than Registrable Securities on any Registration Statement without the prior written consent of the Required Holders.
 
e.  Legal Counsel. Subject to Section 5 hereof, the Required Holders shall have the right to select one legal counsel to review and oversee any registration pursuant to this Section 2, which shall be Schulte Roth & Zabel LLP or such other counsel as is thereafter designated in writing by the Required Holders prior to the initiation of such other legal counsel's review and oversight of any registration ("Legal Counsel"). The Company and Legal Counsel shall reasonably cooperate with each other in performing the Company's obligations under this Agreement.
 
f.  Ineligibility for Form F-3 or Form S-3. In the event that Form F-3 or Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on another appropriate form reasonably acceptable to the Required Holders and (ii) undertake to register the Registrable Securities on Form F-3 or Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form F-3 or Form S-3 covering the Registrable Securities has been declared effective by the SEC.
 
g.  Sufficient Number of ADRs Registered. In the event the number of ADRs available under a Registration Statement filed pursuant to Section 2(a) is insufficient to cover all of the Registrable Securities required to be covered by such Registration Statement or an Investor's allocated portion of the Registrable Securities pursuant to Section 2(c), the Company shall amend the applicable Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover at least the
 
-6-

 

Required Registration Amount, but as of the Trading Day immediately preceding the date of the filing of such amendment or new Registration Statement, in each case, as soon as practicable, but in any event not later than fifteen (15) Business Days after the necessity therefor arises. The Company shall use its best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof. For purposes of the foregoing provision, the number of ADRs available under a Registration Statement shall be deemed "insufficient to cover all of the Registrable Securities" if at any time the number of ADRs available for resale under the Registration Statement is less than the product determined by multiplying (i) the Required Registration Amount by (ii) 0.90. The calculation set forth in the foregoing sentence shall be made without regard to any limitations on the conversion of the Notes or the exercise of the Warrants and such calculation shall assume that the Notes and the Warrants are then convertible into ADRs and are issuable at the then prevailing Interest Conversion Price (as defined in the Notes), Conversion Rate (as defined in the Notes) or Exercise Price (as defined in the Warrants), as applicable.
 
h.  Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement. On the date hereof, as relief for the damages to the holders by reason of the delay prior to the date hereof in their ability to sell the ADRs (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to the holder of Initial Registrable Securities as of the date hereof an amount in cash equal to $129,166.67 (the "Current Failure"). If a Registration Statement covering all of the Initial Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is not declared effective by the SEC on or before the Initial Effectiveness Deadline (an "Initial Effectiveness Failure") then, as partial relief for the damages to any holder by reason of any such delay in or reduction of its ability to sell the ADRs (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each Investor holding Registrable Securities relating to such Registration Statement an amount in cash equal to (i) on the date of such Initial Effectiveness Failure such Investor's pro rata share of $765,000 (computed by dividing the number of Registrable Securities relating to such Registration Statement of such Investor by the total number of Registrable Securities of the Investors relating to such Registration Statement and multiplying the result by $765,000) and (ii) two percent (2.0%) of the aggregate Purchase Price of such Investor's Registrable Securities included in such Registration Statement on every thirtieth day (pro rated for periods totaling less than thirty days) from the date of an Initial Effectiveness Failure until such Initial Effectiveness Failure is cured. If a Registration Statement covering all of the Additional Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is not declared effective by the SEC on or before the Additional Effectiveness Deadline (an "Additional Effectiveness Failure") then, as partial relief for the damages to any holder by reason of any such delay in or reduction of its ability to sell the ADRs (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each Investor holding Registrable Securities relating to such Registration Statement an amount in cash equal to (i) on the date of such Additional Effectiveness Failure an amount in cash equal to such Investor’s pro rata share of seven and one-half percent (7.5%) of the principal amount of Notes then outstanding (computed by dividing the number of Registrable Securities relating to such Registration Statement of such Investor by the total number of Registrable Securities of the Investors relating to such Registration Statement and multiplying the result by seven and one-half percent (7.5%) of the principal amount of Notes
 
-7-

 
 
then outstanding) and (ii) such Investor’s pro rata share of one percent (1.0%) of the principal amount of Notes then outstanding on every thirtieth day (pro rated for periods totaling less than thirty days) from the date of an Additional Effectiveness Failure until such Additional Effectiveness Failure is cured (computed as to each day by dividing the number of Registrable Securities relating to such Registration Statement of such Investor by the total number of Registrable Securities of the Investors relating to such Registration Statement and multiplying the result by one percent (1%) of the principal amount of Notes then outstanding). If (i) a Registration Statement covering all of the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is not, with respect to a Subsequent Registration Statement, (A) filed with the SEC on or before the Subsequent Filing Deadline (a "Subsequent Filing Failure") or (B) declared effective by the SEC on or before the Subsequent Effectiveness Deadline (a "Subsequent Effectiveness Failure"); (ii) a Registration Statement covering all of the Registrable Securities required to be covered thereby and required to be filed by the Company pursuant to this Agreement is not, with respect to an Additional Registration Statement, filed with the SEC on or before the Additional Filing Deadline (an "Additional Filing Failure") (provided that, no Additional Filing Failure shall be deemed to have occurred in the event that the Company withdraws an Additional Registration Statement at request of the SEC filed on or before the Additional Filing Deadline and files a subsequent Additional Registration Statement after the Additional Filing Deadline and prior to the Additional Effectiveness Deadline); or (iii) on any day after the applicable Effective Date (A) sales of all of the Registrable Securities required to be included on such Registration Statement cannot be made (other than during an Allowable Grace Period (as defined in Section 3(r)) pursuant to such Registration Statement (including, without limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or to register a sufficient number of ADRs), or (B) the Registrable Securities are not listed or included for quotation on an Eligible Market (as defined in the Notes) or trading of the ADRs is suspended or halted thereon (other than during an Allowable Trading Grace Period) (each, a "Maintenance Failure"), then, as partial relief for the damages to any holder by reason of any such delay in or reduction of its ability to sell the ADRs (which remedy shall not be exclusive of any other remedies available at law or in equity), the Company shall pay to each holder of Registrable Securities relating to such Registration Statement an amount in cash equal to one and one half percent (1.5%) of the aggregate Purchase Price of such Investor's Registrable Securities included in such Registration Statement on each of the following dates: (A) every thirtieth day (pro rated for periods totaling less than thirty days) after a Subsequent Filing Failure until such Subsequent Filing Failure is cured; (B) every thirtieth day (pro rated for periods totaling less than thirty days) after an Additional Filing Failure until such Additional Filing Failure is cured; (C) every thirtieth day (pro rated for periods totaling less than thirty days) from the date of a Subsequent Effectiveness Failure until such Subsequent Effectiveness Failure is cured; (D) every thirtieth day (pro rated for periods totaling less than thirty days) from the date of an Additional Effectiveness Failure until such Additional Effectiveness Failure is cured; and (E) every thirtieth day (pro rated for periods totaling less than thirty days) from the date of a Maintenance Failure until such Maintenance Failure is cured; provided however that such amount shall not be duplicative or owed more than once with respect to any day which falls within a period described in more than one of clauses (A) through (D) immediately preceding this proviso in this sentence. The payments to which a holder shall be entitled pursuant to this Section 2(g) are referred to herein as "Registration Delay Payments." Registration Delay Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Registration Delay Payments are incurred and (II) the fifth Business Day after the event or failure giving rise to the Registration Delay Payments is cured. In the event the Company fails to make Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of 1.0% per month (prorated for partial months) until paid in full.
 
3.  Related Obligations.
 
At such time as the Company is obligated to file a Registration Statement with the SEC pursuant to Section 2(a), 2(b) or 2(f), the Company will use its reasonable best efforts to effect the registration of the Registrable Securities consistent with the Plan of Distribution and, pursuant thereto, the Company shall have the following obligations:
 
a.  The Company shall promptly prepare and file with the SEC a Registration Statement with respect to the Registrable Securities and use its reasonable best efforts to cause such Registration Statement relating to the Registrable Securities to become effective as soon as practicable after such filing (but in no event later than the Effectiveness Deadline). The Company shall keep each Registration Statement effective pursuant to Rule 415 at all times until the earlier of (i) the date as of which the Investors may sell all of the Registrable Securities covered by such Registration Statement without restriction pursuant to Rule 144(k) (or successor thereto) promulgated under the 1933 Act or (ii) the date on which the Investors shall have sold all the Registrable Securities covered by such Registration Statement (the "Registration Period"), which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. The term "best efforts" shall mean, among other things, that the Company shall submit to the SEC, within four (4) Business Days after the later of the date that (i) Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further comments on the Registration Statement, as the case may be, and (ii) the approval of Legal Counsel pursuant to Section 3(c) (which approval is immediately sought), a request for acceleration of effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request.
 
b.  The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the 1933 Act, as may be necessary to keep such Registration Statement effective at all times during the Registration Period, subject to Allowable Grace Periods, and, during such period, comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company filing a report on Form 10-K or 10-KSB, as applicable, Form 10-Q or 10-QSB, as applicable, or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended (the "1934 Act"), the Company shall have incorporated such report by
 
-8-

 
 
reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the SEC on the same day on which the 1934 Act report is filed which created the requirement for the Company to amend or supplement such Registration Statement.
 
c.  The Company shall (A) permit Legal Counsel to review and comment upon (i) a Registration Statement at least five (5) Business Days prior to its filing with the SEC and (ii) all amendments and supplements to all Registration Statements (except for reports incorporated by reference therein) within a reasonable number of days prior to their filing with the SEC, and (B) not file any Registration Statement or amendment or supplement thereto in a form to which Legal Counsel reasonably objects. The Company shall not submit a request for acceleration of the effectiveness of a Registration Statement or any amendment or supplement thereto without the prior approval of Legal Counsel, which consent shall not be unreasonably withheld. The Company shall furnish to Legal Counsel, without charge, (i) copies of any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to any Registration Statement, (ii) promptly after the same is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, and all exhibits and (iii) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto. The Company shall reasonably cooperate with Legal Counsel in performing the Company's obligations pursuant to this Section 3.
 
d.  The Company shall furnish to each Investor whose Registrable Securities are included in any Registration Statement, without charge, (i) promptly after the same is prepared and filed with the SEC, at least one copy of such Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference, if requested by an Investor, all exhibits and each preliminary prospectus, (ii) upon the effectiveness of any Registration Statement, ten (10) copies of the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as such Investor may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by such Investor.

f.  The Company shall notify Legal Counsel and each Investor in writing, of the happening of any event, as promptly as practicable after becoming aware of such event, as a result of which the prospectus included in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (provided that in no event shall such notice contain any material, nonpublic information), and, subject to Section 3(r), promptly prepare a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and deliver ten (10) copies of such supplement or amendment to Legal Counsel and each Investor (or such other number of copies as Legal Counsel or such Investor may reasonably request).

The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt written notice to such Investor and allow such Investor, at the Investor's expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

p.  The Company shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC in connection with any registration hereunder.

The provisions of Sections 2(f) and 3(e) hereof shall not be applicable during the period of any Allowable Grace Period. Upon expiration of the Grace Period, the Company shall again be bound by the first sentence of Section 3(f) with respect to the information giving rise thereto unless such material non-public information is no longer applicable. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended certificates for ADRs to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale, and delivered a copy of the prospectus included as part of the applicable Registration Statement, prior to the Investor's receipt of the notice of a Grace Period and for which the Investor has not yet settled.
 
Notwithstanding anything to the contrary herein, the Company may suspend trading of its equity securities on the applicable Eligible Market on which its equity securities are then trading, due to the existence of material, non-public information concerning the Company the disclosure of which at the time is not, in the good faith opinion of the Board of Directors of the Company and its counsel, in the best interest of the Company (a "Trading Grace Period"); provided, that the Company shall promptly (i) notify the Investors in writing of the existence of such suspension (provided that in each notice the Company will not disclose the content of any material, non-public information to the Investors) and the date on which the Trading Grace Period will begin, and (ii) notify the Investors in writing of the date on which the Trading Grace Period ends; and, provided further, that no Trading Grace Period shall exceed 5 consecutive days and during any 365 day period such Trading Grace Periods shall not exceed an aggregate of 15 days and the first day of any Trading Grace Period must be at least 2 Trading Days after the last day of any prior Trading Grace Period (an "Allowable Grace Trading Period").

It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it, as shall be reasonably required to effect and maintain the effectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request.
 
b.  Each Investor, by such Investor's acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor's election to exclude all of such Investor's Registrable Securities from such Registration Statement.
 
c.  Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of 3(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until such Investor's receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(g) or the first sentence of 3(f) or receipt of notice that no supplement or amendment is required. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended certificates for ADRs to a transferee of an Investor in accordance with the terms of the Securities Purchase Agreement in connection with any sale of Registrable Securities with respect to which an Investor has entered into a contract for sale prior to the Investor's receipt of a notice from the Company of the happening of any event of the kind described in Section 3(g) or the first sentence of 3(f) and for which the Investor has not yet settled.

6.  Indemnification.
 
In the event any Registrable Securities are included in a Registration Statement under this Agreement:
 
a.  To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor, the directors, officers, partners, members, employees, agents, representatives of, and each Person, if any, who controls any Investor within the meaning of the 1933 Act or the 1934 Act (each, an "Indemnified Person"), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys' fees, amounts paid in settlement or expenses, joint or several, (collectively, "Claims") incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto ("Indemnified Damages"), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under the securities or other "blue sky" laws of any jurisdiction in which Registrable Securities are offered ("Blue Sky Filing"), or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii) any violation or alleged violation by the Company of the 1933 Act, the 1934 Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement or (iv) any material violation of this Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, "Violations"). Subject to Section 6(c), the Company shall reimburse the Indemnified Persons, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person for such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 3(d); (ii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the prospectus made available by the Company, including a corrected prospectus, if such prospectus or corrected prospectus was timely made available by the Company pursuant to Section 3(d); and (iii) shall not apply to amounts paid in settlement of any Claim if such
 
-15-

 
 
settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9.
 
b.  In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement and each Person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act (each, an "Indemnified Party"), against any Claim or Indemnified Damages to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 6(c), such Investor will reimburse any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld or delayed; provided, further, however, that the Investor shall be liable under this Section 6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented.
 
c.  Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses of not more than one counsel for such Indemnified Person or Indemnified Party to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party
 
-16-

 
 
and any other party represented by such counsel in such proceeding. In the case of an Indemnified Person, legal counsel referred to in the immediately preceding sentence shall be selected by the Required Holders to which the Claim relates. The Indemnified Party or Indemnified Person shall cooperate reasonably with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or Claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such Claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.
 
d.  The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when Indemnified Damages are incurred and applicable bills are received.
 
e.  The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.
 
f.  Nothing herein shall the right of any party to this Agreement to bring a contractual claim against any other party to this Agreement for a breach of this Agreement.
 
7.  Contribution.
 
To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no person involved in the sale of Registrable Securities which person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) in connection with such sale shall be entitled to contribution from any person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in

a.  make and keep public information available, as those terms are understood and defined in Rule 144;
 
b.  file with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the 1934 Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company's obligations under Section 4(c) of the Securities Purchase Agreement) and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and
 
c.  furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, to the extent not available on EDGAR, and (iii) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration.
 
9.  Assignment of Registration Rights.

No such amendment shall be effective to the extent that it applies to less than all of the holders of the Registrable Securities.

e.  All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

Re: PSIVIDA LIMITED
 
Ladies and Gentlemen:
 
We are counsel to pSivida Limited, an Australian corporation (the "Company"), and have represented the Company in connection with that certain Amendment Agreement (the "Purchase Agreement") entered into by and among the Company and the buyers named therein (collectively, the "Holders") pursuant to which the Company issued to the Holders notes convertible into the Company's ADRs (as converted, the "Conversion Shares"), and warrants (the "Warrants") exercisable for Ordinary Shares (the "Warrant Shares"). Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement with the Holders (the "Registration Rights Agreement") pursuant to which the Company agreed, among other things, to register the resale of the Registrable Securities (as defined in the Registration Rights Agreement), including the ADRs issuable upon conversion of the Notes, as interest on the Notes and upon exercise of the Warrants under the Securities Act of 1933, as amended (the "1933 Act"). In connection with the Company's obligations under the Registration Rights Agreement, on ____________ ___, 2006, the Company filed a Registration Statement on Form F-3 (File No. 333-_____________) (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") relating to the Registrable Securities which names each of the Holders as a selling stockholder thereunder.
 
In connection with the foregoing, we advise you that a member of the SEC's staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the SEC's staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable Securities are available for resale under the 1933 Act pursuant to the Registration Statement.
 
A-1

 
 
This letter shall serve as our standing opinion to you that the ADRs are freely transferable by the Holders pursuant to the Registration Statement. You need not require further letters from us to effect any future legend-free issuance or reissuance of ADRs to the Holders as contemplated by the Company's Irrevocable Transfer Agent Instructions dated September 14, 2006. This letter shall serve as our standing instructions to you with regard to this matter.
 
Very truly yours,
 
[ISSUER'S COUNSEL]

EXHIBIT B

SELLING STOCKHOLDERS
 
The ADRs being offered by the selling stockholders are issuable (i) upon conversion of the convertible notes, (ii) as interest on the convertible notes and (iii) upon exercise of the warrants. For additional information regarding the notes and warrants, see "Private Placement of Convertible Notes and Warrants" above. We are registering the ADRs in order to permit the selling stockholders to offer the ADRs for resale from time to time. Except for the ownership of the notes and the warrants, the selling stockholders have not had any material relationship with us within the past three years.
 
The table below lists the selling stockholders and other information regarding the beneficial ownership of the ordinary shares underlying the ADRs by each of the selling stockholders. The second column lists the number of ordinary shares beneficially owned (directly or indirectly through ADRs) by each selling stockholder, based on its ownership of the notes and the warrants, as of ________, 2006, assuming conversion of all the notes and exercise of all warrants held by the selling stockholders on that date, without regard to any limitations on conversions or exercise.
 
The third column lists the ordinary shares being offered by this prospectus by the selling stockholders.
 
In accordance with the terms of registration rights agreements with the holders of the notes and the warrants, this prospectus generally covers the resale of at least 130% of the sum of (i) the maximum number of ADRs issuable upon conversion of the notes (assuming that the notes are convertible at their initial Conversion Price and without taking into account any limitations on the conversion of the notes set forth in such notes), (ii) the maximum number of ADRs issuable upon exercise of the related warrants (without taking into account any limitations on the exercise of the warrants set forth in the warrants) and (iii) as interest on the convertible notes, in each case as of the Trading Day immediately preceding the date this registration statement was initially filed with the SEC. Because the conversion price of the notes and the exercise price of the warrants may be adjusted, the number of ADRs that will actually be issued may be more or less than the number of ADRs being offered by this prospectus. The fourth column assumes the sale of all of the ADRs offered by the selling stockholders pursuant to this prospectus.
 
Under the terms of the notes and the warrants, a selling stockholder may not convert the notes, or exercise the warrants, to the extent such conversion or exercise would cause such selling stockholder, together with its affiliates, to beneficially own a number of ordinary shares (directly or indirectly through ADRs) which would exceed 4.99% of our then outstanding ordinary shares following such conversion or exercise, excluding for purposes of such determination ordinary shares issuable upon conversion of the notes which have not been converted and upon exercise of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The selling stockholders may sell all, some or none of their ADRs in this offering. See "Plan of Distribution."

Sandell Asset Management Corp. and Thomas E. Sandell, its sole shareholder, disclaim beneficial ownership of the securities owned by Castlerigg.

PLAN OF DISTRIBUTION
 
We are registering the ADRs issuable upon conversion of the notes and upon exercise of the warrants and as interest on the convertible notes to permit the resale of these ADRs by the holders of the notes and the warrants from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the ADRs. We will bear all fees and expenses incident to our obligation to register the ADRs.
 
The selling stockholders may sell all or a portion of the ADRs beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the ADRs are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent's commissions. The ADRs may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions,
 
·  
on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;
 
·  
in the over-the-counter market;
 
·  
in transactions otherwise than on these exchanges or systems or in the over-the-counter market;
 
·  
through the writing of options, whether such options are listed on an options exchange or otherwise;
 
·  
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
 
·  
block trades in which the broker-dealer will attempt to sell the ADRs as agent but may position and resell a portion of the block as principal to facilitate the transaction;
 
·  
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
 
·  
an exchange distribution in accordance with the rules of the applicable exchange;
 
·  
privately negotiated transactions;
 
·  
short sales;
 
·  
pursuant to Rule 144 under the Securities Act;
 
·  
broker-dealers may agree with the selling securityholders to sell a specified number of such ADRs at a stipulated price per ADR;
 
·  
a combination of any such methods of sale; and

 
B-3

 
 
·  
any other method permitted pursuant to applicable law.
 
If the selling stockholders effect such transactions by selling ADRs to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the ADRs for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the ADRs or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the ADRs in the course of hedging in positions they assume. The selling stockholders may also sell ADRs short and deliver ADRs covered by this prospectus to close out short positions. The selling stockholders may also loan or pledge ADRs to broker-dealers that in turn may sell such ADRs.
 
The selling stockholders may pledge or grant a security interest in some or all of the notes, warrants or the ADRs owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the ADRs from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the ADRs in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
 
The selling stockholders and any broker-dealer participating in the distribution of the ADRs may be deemed to be "underwriters" within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the ADRs is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of ADRs being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.
 
Under the securities laws of some states, the ADRs may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the ADRs may not be sold unless such ADRs have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
 
There can be no assurance that any selling stockholder will sell any or all of the ADRs registered pursuant to the shelf registration statement, of which this prospectus forms a part.
 
The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange
 
B-4

 

Act, which may limit the timing of purchases and sales of any of the ADRs by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the ADRs to engage in market-making activities with respect to the ADRs. All of the foregoing may affect the marketability of the ADRs and the ability of any person or entity to engage in market-making activities with respect to the ADRs.
 
We will pay all expenses of the registration of the ADRs pursuant to the registration rights agreement, estimated to be $[     ] in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or "blue sky" laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, in accordance with the registration rights agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related registration rights agreements, or we may be entitled to contribution.
 
Once sold under the shelf registration statement, of which this prospectus forms a part, the ADRs will be freely tradable in the hands of persons other than our affiliates.

ASX/MEDIA RELEASE

pSivida completes agreement with existing
Convertible Note Holder
 

 
Boston, MA. and Perth, Australia - Global bio-nanotech company pSivida Limited (ASX:PSD, NASDAQ:PSDV, Xetra:PSI) is pleased to announce that the definitive documentation related to the previously announced renegotiated terms of the Convertible Note dated 16 November 2005 between the Company and Castlerigg Master Investments Ltd. has been completed.

The renegotiated terms provided for the lifting of restrictions on future sales of securities enabling the Company to enter into additional capital raising transactions, which the Company will be seeking to do.

The renegotiated terms also provided for an extension to October 15, 2006 of the registration deadline under the Company’s registration rights agreement with the note holder. The delays in the registration statement being declared effective have been a direct result of complex accounting issues associated with the Company’s recent acquisition and the convertible note, the change-over in Australia from Australian GAAP to Australian IFRS and the reconciliation of the Company’s financial statements prepared under that new accounting scheme to U.S. GAAP.

The Company will hold an Extraordinary General Meeting in Perth on 19 September 2006 to consider resolutions relating to the ratification of the renegotiation of Convertible Notes and the approval of other pending financing transactions.

THIS RELEASE SHALL NOT CONSTITUTE AN OFFER TO SELL OR A SOLICITATION OF AN OFFER TO BUY ANY SECURITIES DESCRIBED HEREIN.

THE SECURITIES DESCRIBED HEREIN HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED OR SOLD IN THE UNITED STATES ABSENT REGISTRATION OR AN APPLICABLE EXEMPTION FROM REGISTRATION REQUIREMENTS.

This document contains forward-looking statements that involve risks and uncertainties. The statements reference potential products, applications and regulatory approvals. Although we believe that the expectations reflected in such forward-looking statements are reasonable at this time, we can give no assurance that such expectations will prove to be correct. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Actual results could differ materially from those anticipated in these forward-looking statements due to many important factors including: our inability to raise additional funds at favourable terms or any terms; our inability to repay the amended notes; issues relating to share registration in the U.S. that may delay our registration; our inability to develop proposed products, including without limitation, in the drug delivery, wound healing, orthopaedics, and tissue engineering, diagnostics and food technology fields; failure of our evaluation agreements to result in license agreements; failure to develop applications for BioSilicon™ due to regulatory, scientific or other issues; failure to complete negotiations for new centers for the BrachySil™ phase IIb clinical trial for inoperable primary liver cancer; failure of our discussions with the FDA for BrachySil™ to continue or to lead to FDA approval; failure of the BrachySil™ phase IIb clinical trial for inoperable primary liver cancer to determine the optimal dose, provide key safety data or support future pivotal efficacy trials or product registration or approval; failure of the BrachySil™ primary liver programme that is in phase IIb clinical trials to provide a valuable platform for the development and commercialisation of BrachySil™ for pancreatic cancer and other indications; failure to commence phase IIa BrachySilTM trials for the treatment of pancreatic cancer; failure of the findings of the pancreatic cancer phase IIa trial to provide a platform for further multicentre efficacy and safety trials; failure of there to be optimisation and standardisation between our two  pancreatic cancer study centres; failure of the results of the Retisert™ for DME trial to be a good indicator of the results of pSivida’s ongoing phase III Medidur™ for DME trial; failure of the Medidur™ trials in DME to show a very similar improvement in visual acuity and diabetic retinopathy severity score as Retisert™ for DME; failure of Medidur™ to release fluocinolone acetonide at the same rate as Retisert™; our inability to recruit patients for the phase III Medidur™ for DME trial. Other reasons are contained in cautionary statements in the Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission, including, without limitation, under Item 3.D, "Risk Factors" therein. We do not undertake to update any oral or written forward-looking statements that may be made by or on behalf of pSivida.
